A frame 1, on which a film material placement plate 14 is provided, and a slot 141 is provided in the center of the film material placement plate 14;

The conveying module shown in FIG6 includes a moving seat 21 and a first driving device for driving the moving seat 21 to move in a vertical direction, and a clamping device is provided on the moving seat 21;

The film pressing assembly 3 includes a pair of sliding seats 32, which are horizontally slidably arranged on the frame 1, a pair of sliding seats 32 are arranged on both sides below the insertion slot 141, and a pair of sliding seats 32 are symmetrically arranged on both sides of the moving seat 21. A roller body 31 driven by rotation is arranged on the sliding seat 32, and a transmission connecting rod 33 is rotatably connected to the sliding seat 32. The transmission connecting rod 33 is rotatably arranged on the moving seat 21 at one end away from the sliding seat 32;

The clamping device is used to clamp the bottom of the sheet material 9 inserted into the insertion slot 141, and the first driving device is used to drive the movable seat 21 to move downward until the position to be coated of the clamped material is consistent with the center height of the roller body 31. Due to the transmission connection of the transmission connecting rod 33, a pair of sliding seats 32 move synchronously relative to each other in the horizontal direction until a pair of roller bodies 31 are attached to both sides of the material.

The double-sided laminating process of the sheet material is to press the vertically arranged sheet material down to the center of the horizontally placed film material, and pass it through a pair of pressing rollers to achieve double-sided laminating of the sheet material. Before performing the laminating action, it is necessary to clamp the lower end of the sheet material and move the sheet material and the film material as a whole, so that the lower ends of the sheet material and the film material move between the pair of pressing rollers, and then move the pair of pressing rollers to press the film material on both sides of the sheet material. The above action requires two working cycles to complete. The inventor believes that the above action is complex to control and the work efficiency is not high, which needs to be improved.

Based on the above structure, a double-sided laminating device for a flat sheet of film material includes the following steps when used:

S1. Lay the flat sheet of film 8 flat on the film placement plate 14. A groove 81 is preset in the center of the flat sheet of film 8. The groove 81 is aligned with the insertion slit 141. An extension plate 91 passing through the groove 81 is provided at the lower end of the sheet 9. A pair of bottom edges 92 are provided on both sides of the sheet 9 corresponding to the proximal end of the extension plate 91 (i.e., the extension plate 91 is close to one end of the sheet 9). The sheet 9 is vertically placed above the insertion slit 141. The extension plate 91 penetrates the groove 81 from top to bottom so that the bottom edge 92 fits the upper end of the flat sheet of film 8. At this time, the extension plate 91 penetrates the insertion slit 141.

S2, as shown in FIG16 , clamping the bottom of the sheet material 9 by a clamping device;

S3, as shown in FIG17, the first driving device is used to drive the moving seat 21 to move downward to the position where the clamped material is to be coated, that is, the proximal end of the extension plate 91 is consistent with the center height of the roller body 31, at this time, the pair of sliding seats 32 synchronously move relative to each other in the horizontal direction until the pair of roller bodies 31 are attached to both sides of the sheet material 9, and the lower end of the flat film material 8 is pressed onto the sheet material 9;

S4, the clamping device releases the sheet 9;

S5. As shown in Figure 18, a pair of rollers 31 are driven to rotate, and the pair of rollers 31 rotate in opposite directions. The pair of rollers 31 press the film materials on both sides of the groove 81 onto both sides of the sheet material 9 respectively, and at the same time push the sheet material 9 that has completed the coating to move downward. After the sheet material 9 and the flat film material 8 completely pass through the pair of rollers 31, the flat film material 8 adheres to both sides of the sheet material 9.

Therefore, a double-sided laminating device for flat sheet film material of the present application realizes the synchronous operation of vertical positioning of the sheet material 9 and horizontal positioning of the roller body 31 by realizing the linkage movement of the movable seat 21 and the sliding seat 32 through the transmission connecting rod 33, and uses one driving device as a whole, thereby reducing manufacturing costs and improving production efficiency.

In this embodiment, the first driving device is a driving cylinder 4, the fixed component of the driving cylinder 4 is installed on the frame 1, the movable component of the driving cylinder 4 is connected to one of the sliding seats 32, and the driving cylinder 4 is used to drive the sliding seat 32 to move horizontally. The driving cylinder 4 is arranged as a whole laterally on the outside of the sliding seat 32, and drives the horizontal movement of the sliding seat 32 to drive the synchronous vertical movement of the moving seat 21. In other embodiments, the driving cylinders 4 are arranged in pairs, and each pair of sliding seats 32 is synchronously driven.

In this embodiment, the hinge point of the transmission connecting rod 33 at one end of the sliding seat 32 is the rotating axis of the roller body 31 , and the hinge point of the transmission connecting rod 33 at one end of the sliding seat 32 is located obliquely above the hinge point on the moving seat 21 .

In this embodiment, as shown in FIG6 , a positioning block 321 is provided between a pair of sliding seats 32. When the pair of sliding seats 32 move horizontally in relative directions, they are finally limited on both sides of the positioning block 321. At this time, the pair of rollers 31 are attached to both sides of the material. The positioning block 321 is used to limit the movement of the pair of sliding seats 32 in relative directions. In this embodiment, a top plate 3211 is provided on the upper end of the positioning block 321. The top plate 3211 is fixed on the sliding seat 32. The positioning block 321 extends to the front end of the sliding seat 32. The positioning block 321 is arranged on the sliding seat 32 near the driving cylinder 4.

As shown in FIG3 , in this embodiment, a group of right-angle positioning blocks 142 are further included. The right-angle positioning blocks 142 are arranged on the film material placement plate 14. The group of right-angle positioning blocks 142 respectively correspond to the four right angles of the rectangular placement area on the film material placement plate 14. The right-angle profile of the right-angle positioning blocks 142 increases linearly from bottom to top. The right-angle positioning blocks 142 are used to position the four corners of the flat film material 8 placed on the film material placement plate 14. The right-angle profile of the right-angle positioning blocks 142 increases linearly from bottom to top, so as to facilitate the placement of the flat film material 8 from top to bottom into the placement cavity formed by the right-angle positioning blocks 142.

As shown in FIGS. 4 and 5 , in this embodiment, a pressing wheel assembly 15 is further included. The pressing wheel assembly 15 includes:

The pressing wheel assemblies 15 are arranged in pairs on both sides of the film material placement plate 14 .

When in use, the pressing wheel 151 is pressed against the upper end of the flat film material 8 by rotating the mounting rod 153. The rotation direction of the pressing wheel 151 corresponds to the moving direction of the flat film material 8 on the film material placement plate 14, ensuring that the flat film material 8 is in contact with the film material placement plate 14 before entering the insertion slot 141, and preventing the flat film material 8 from warping or wrinkling during movement. In this embodiment, when the pressing wheel 151 is pressed against the flat film material 8, the rotating axis of the pressing wheel 151 is parallel to the film material placement plate 14 and perpendicular to the moving direction of the flat film material 8 on the film material placement plate 14. Specifically, the radial cross-section of the outer edge of the pressing wheel 151 is semicircular. Two pairs of pressing wheel assemblies 15 are provided on both sides of the insertion slot 141. In order to prevent the pressing wheel 151 from leaving marks on the flat film material 8, the flat film material 8 is wider than the lateral dimension of the sheet material 9 in the width direction, and the pressing wheel 151 is pressed against the portion of the flat film material 8 that exceeds the outer edge of the sheet material 9. In this embodiment, the pressure wheel frame 152 includes a hinged seat 1521, and the mounting rod 153 is arranged on the hinged seat 1521.

Subsequently, the mounting rod 153 is rotated to within the range of the arc groove 1520 and pressed on the flat film material 8. The mounting rod 153 is locked on the arc groove 1520 by the locking component to ensure the stability of the pressing wheel 151 pressing on the flat film material 8. In this embodiment, the locking component includes a limit screw 154 and a locking nut 155. The limit screw 154 is installed on the mounting rod 153. The radial dimension of the limit screw 154 is adapted to the width of the arc groove 1520. The locking nut 155 is arranged at the front end of the mounting rod 153. When the mounting rod 153 is rotated to within the range of the arc groove 1520, the limit screw 154 is axially penetrated in the arc groove 1520. At this time, the locking nut 155 is tightened, and the mounting rod 153 can be locked on the arc groove 1520.

Specifically, the movable block 22 is rotatably disposed on the movable seat 21, and the movable block 22 can switch between a first posture, a second posture and a third posture; the rotating shaft of the movable block 22 is disposed on one side of the cavity 210, and the positioning tongue 221 and the chuck 222 are extended and disposed on the movable block 22;

As shown in FIG. 13 , when the movable block 22 is in the first posture, the positioning tongue 221 extends into the cavity 210 from one side of the cavity 210 , and the positioning tongue 221 is used to support the bottom of the sheet material 9 that penetrates into the cavity 210 ;

As shown in FIG. 14 , when the movable block 22 is in the second posture, the chuck 222 extends into the cavity 210 from one side of the cavity 210 , and the sheet material 9 that penetrates into the cavity 210 is pressed against the side wall of the cavity 210 away from the movable block 22 by the chuck 222 ;

As shown in FIG. 15 , when the movable block 22 is in the third posture, the positioning tongue 221 and the clamping head 222 rotate out of the cavity 210 .

As shown in FIG8 , in this embodiment, one of the clamping plates 211 is a mounting plate 2111, and the movable block 22 is arranged on the mounting plate 2111. Correspondingly, the mounting plate 2111 is provided with an active cavity 2110 for accommodating the movable block 22 for rotation, and the movable block 22 is provided with a transmission guide surface 223; the mounting plate 2111 is provided with a first cylinder 23 which is transmission-connected with the movable block 22, and the upper end of the telescopic rod of the first cylinder 23 is provided with a roller 231; when the movable block 22 is in the first posture, the transmission guide surface 223 extends out of the mounting plate 2111 away from the side of the cavity 210, and the first cylinder 23 is arranged below the transmission guide surface 223, and the transmission guide surface 223 and the roller 231 are arranged opposite to each other;

When the telescopic rod of the first cylinder 23 is pushed out, the roller 231 can push the transmission guide surface 223 extending from the mounting plate 2111 to rotate the movable block 22 to the second posture. Specifically, the number of the first cylinders 23 is 2, which are symmetrically arranged along the width direction of the movable block 22. In this embodiment, the transmission guide surface 223 is an inwardly concave arc surface tangent to the limiting hook 224. When the movable block 22 is in the first posture and is clamped, the roller 231 is pushed out by the first cylinder 23 to push the transmission guide surface 223, so that the movable block 22 rotates along the B direction to the second posture. It should be noted that in this embodiment, during the process of the movable block 22 switching from the first posture to the second posture, the sheet material 9 will have a certain degree of falling tendency, and the pressure wheel assembly 15 presses the flat film material 8 to generate a certain pulling force, which can overcome the falling of the sheet material 9 in this process. In this embodiment, a limit hook 224 is extended from the far end of the transmission guide surface 223. When the movable block 22 is in the second posture, the transmission guide surface 223 rotates to the inside of the movable cavity 2110, and the limit hook 224 extends out of the mounting plate 2111. The roller 231 abuts against the limit hook 224, and the limit hook 224 is attached to the oblique upper part of the roller 231. It should be noted that the "far end" of the rotating component defined in this application is the end of each component away from the rotating axis. In this embodiment, the inner side of the limit hook 224 is an arc surface adapted to the outer edge of the roller 231. The limit hook 224 is used to limit the roller 231 from extending too far forward, and convert the thrust of the roller 231 from the front to the torque for rotating the movable block 22 in the pressing direction.

In this embodiment, a positioning surface 2211 is provided on one side of the positioning tongue 221. When the movable block 22 is in the first posture, the positioning surface 2211 faces upward to support the bottom of the sheet material 9;

As shown in FIGS. 13 and 15 , a driving surface 2212 is provided on the side of the positioning tongue 221 away from the positioning surface 2211; the positioning tongue 221 also includes a top piece 12, which is fixed to the frame 1, and is vertically arranged. The top piece 12 is arranged below the movable block 22, and a through groove 21110 is provided at the lower end of the mounting plate 2111 corresponding to the top piece 12, and the through groove 21110 vertically extends into the movable cavity 2110;

When the movable block 22 is in the second posture, the driving surface 2212 is located at the lower end of the movable block 22, and the upper end of the top member 12 is directly opposite to the driving surface 2212. At this time, after the second driving device drives the movable seat 21 to descend a preset distance, the top member 12 is used to push the driving surface 2212 to make the movable block 22 rotate to the third posture. Specifically, the driving surface 2212 is arc-shaped, one end of the driving surface 2212 extends to intersect with the far end of the positioning surface 2211, and the other end of the driving surface 2212 is connected to the transmission guide surface 223. The driving surface 2212 on the movable block 22 is resisted by the top member 12, so that the movable block 22 rotates from the second posture to the third posture. During this process, the positioning tongue 221 rotates toward the side of the cavity 210, and on the contrary, the chuck 222 rotates toward the side away from the cavity 210. In the third posture, the positioning tongue 221 is still in the movable cavity 2110 as a whole, and the chuck 222 rotates into the movable cavity 2110 as a whole. At the same time, the limit hook 224 rotates downward synchronously, and the roller 231 is pressed by the limit hook 224, so that the telescopic rod of the first cylinder 23 is retracted as a whole. It should be noted that when the roller 231 is pressed downward when the first cylinder 23 is in the extended state, the roller 231, i.e., the telescopic rod of the cylinder, can be retracted to a preset size when the downward pressure on the roller 231 is greater than the outward thrust of the cylinder body on the telescopic rod of the first cylinder 23. At this time, the limit hook 224 is used to convert the force generated by the movable block 22 rotating toward the third posture into a force to press the roller 231 downward.

As shown in FIG15 , a roller 121 is rotatably provided at the upper end of the top member 12. When the roller 121 is in contact with the driving surface 2212, it is tangent to point A in the cross section. Point A is on the side of the straight line near the cavity 210 where the rotation center of the movable block 22 is located. Specifically, the top member 12 is always arranged in the through groove 21110. The top member 12 is a vertically arranged plate.

As shown in FIG8 , in this embodiment, torsion springs 24 are provided on both sides of the movable block 22, and the torsion springs 24 are coaxially arranged with the rotating shaft of the movable block 22. A pair of extension legs 241 are provided at both ends of the torsion spring 24, and the pair of extension legs 241 are connected to the movable block 22 and the moving seat 21 respectively. Specifically, spring grooves adapted to the extension legs 241 are provided on the movable block 22 and the moving seat 21, and a limiting surface 21101 is provided in the movable cavity 2110; the torsion spring 24 is used to apply a torque to the movable block 22 so that the movable block 22 abuts against the limited surface 21101 in a natural state, and the movable block 22 is in the first posture at this time; when the movable block 22 is in the second posture and the third posture, the torsion spring 24 is in a compressed energy storage state. When the first cylinder 23 retracts until the roller 231 is disengaged from the transmission guide surface 223, the torsion spring 24 can reset the movable block 22 to the first posture. In addition, in this embodiment, the mounting plate 2111 is connected to the mounting block 21111, the mounting block 21111 is embedded in the mounting plate 2111, the movable block 22 is rotatably arranged on the mounting block 21111, and the movable cavity 2110 is arranged on the mounting block 21111. Correspondingly, the torsion spring 24 is also arranged on the mounting block 21111, and the processing difficulty of the mounting plate 2111 can be reduced by the split mounting block 21111.
