Referring to fig. 1, the embodiment of the application discloses a joint method of a slitting machine, which comprises the following steps:

opening the pedal part 3;

cutting the processed film section and the film section to be processed on the cutting part 63 in the pedal part 3;

after cutting, the waste material is moved out of the pedal part 3;

after the waste material is moved out of the pedal part 3, the processed film section and the film section to be processed are butted through an adhesive tape.

By the method, the space in the pedal part 3 can be fully utilized, and the positions of the two films to be butted can be controlled by controlling the films, so that the butting quality can be controlled.

And closing the pedal part 3 after the processed film section is butted with the film section to be processed.

In the step "cutting the processed film piece and the film piece to be processed placed on the cut portion 63 in the step portion 3", the processed film piece is partially wound around the dividing mechanism 2, and the film piece to be processed is partially wound around the winding mechanism 1.

The step of cutting the processed film segment and the film segment to be processed placed on the cut portion 63 in the step portion 3 includes: the processed film section and the film section to be processed are partially overlapped, and the overlapped part of the film section and the film section to be processed is cut off according to the cutting part 63. The step of partially overlapping the processed film segment and the film segment to be processed and cutting the overlapped portion according to the cutting part 63 includes synchronously pressing the processed film segment and the film segment to be processed by two pressing blocks (a first pressing block 66 and a second pressing block 67) which can move in the vertical direction, respectively.

Referring to fig. 2 to 4, the embodiment of the application discloses a strip separator easy to connect, which includes a rolling mechanism 1 and a strip separating mechanism 2, a pedal portion 3 is disposed between the rolling mechanism 1 and the strip separating mechanism 2, and the pedal portion 3 includes a base 31 and a pedal cover 32 rotatably disposed around the base 31; a joint mechanism 6 is arranged in the pedal portion 3, the joint mechanism 6 comprises a bottom plate 61 and a pressing plate 62 capable of moving relative to the bottom plate 61 along the vertical direction, and a cutting portion 63 for cutting is formed on the bottom plate 61.

By means of the structure, when the film joint is needed, the pedal cover 32 can be turned up, then the two layers of films are overlapped, the two layers of films are pressed through the pressing plate 62, then the two layers of films are cut through the cutting part 63, and the two films are butted after being cut. With the structure, the lower space of the pedal cover 32 is used, so the working space is greatly saved, and the working environment is facilitated. Meanwhile, the cutting part 63 and the pressing plate 62 can provide a good positioning and supporting effect for the two layers of films, and the joint operation can be efficiently realized with high quality only by one operator.

Referring mainly to fig. 2 and 3, specifically, the rolling-in mechanism 1 is located on the side of the pedal portion 3, and the rolling-in mechanism 1 is located above the pedal portion 3. The strip dividing mechanism 2 is arranged on the other side of the pedal part 3, and the strip dividing mechanism 2 is arranged above the pedal part 3. That is, the reel-in mechanism 1, the stripping mechanism 2, and the pedal portion 3 extend in the X-axis direction. Specifically, the stripping mechanism 2 includes a stripping shaft, and a control system 21 and an operation portion 22 provided at both ends of the stripping shaft, and a length of the pedal portion 3 in a direction perpendicular to the X axis is the same as a length of the stripping shaft in a direction perpendicular to the X axis.

Preferably, a first guide wheel 4 may be provided between the reel-in mechanism 1 and the pedal portion 3, and a second guide wheel 5 may be provided between the striping mechanism 2 and the pedal portion 3. The film fed from the winding mechanism 1 to the slitting mechanism 2 can horizontally pass through the inside of the step portion 3 by the first guide wheel 4 and the second guide wheel 5. Of course, in other alternative structures, the film may be provided so as to pass through the inside of the step portion 3.

The reel-in mechanism 1 includes an input shaft rotatable about its axis. Under the action of the rotation of the input shaft, the film roll arranged thereon can be gradually output to the slitting mechanism 2. The structure of the slitting mechanism 2 is similar to that of the slitting mechanism 2 in the prior art, and is used for cutting the film passing over the slitting mechanism in a direction perpendicular to the X-axis (i.e., the width direction of the film).

Referring to fig. 3, the step portion 3 includes a base 31 and a step cover 32 rotatably provided around the base 31. In the present embodiment, the pedal cover 32 can rotate relative to the base 31 about a pivot. In particular, a base is arranged on one side of the slitting mechanism 2. When the pedal cover 32 is in the open state, the stand can give support to the pedal cover 32 to facilitate positioning of the pedal cover 32.

In particular, the base 31 may extend in the film width direction (the direction perpendicular to the X axis). The base 31 is a rectangular parallelepiped frame made of a plurality of bar members. The membrane may pass through the hollow portion of the frame.

Referring mainly to fig. 4, the joint mechanism 6 includes a base plate 61 and a pressing plate 62. The base plate 61 is fixedly disposed on the base 31. And a base plate 61 is located below the film. During normal operation of the film, the film does not contact the base plate 61. The bottom plate 61 comprises a first lining plate 64 fixed on the base 31 and a second lining plate 65 fixedly arranged on the first lining plate 64, the second lining plate 65 is positioned above the first lining plate 64, and the cutting part 63 is formed by an inclined surface of the second lining plate 65 positioned above the first lining plate 64. Of course, in other alternative embodiments, the first liner 64 and the second liner 65 may be arranged in parallel, and the first liner 64 and the second liner 65 may form the cut-out 63 with a gap therebetween. The cutting part 63 can guide the cutting of the films in the cutting process, and the matching degree of the shapes of the two films needing to be butted after cutting is guaranteed. Preferably, the cut-out 63 is inclined. That is, the extending direction of the cutting portion 63 forms an angle different from 0 degree or 90 degrees with the X-axis.

The pressing plate 62 can reciprocate in the vertical direction by the driving mechanism. The driving mechanism can be a power device with a driving function, such as an air cylinder or an oil cylinder. During the docking process, the drive mechanism may drive the pressure plate 62 against the two films to be docked. Therefore, the two films can be ensured to be in a stable state, so that the butt joint operation is facilitated.

In the present embodiment, the driving mechanism can drive a connecting unit to reciprocate along the vertical direction, and the connecting unit is fixedly connected with the two pressing blocks (the first pressing block 66 and the second pressing block 67). And these two pressing pieces (first pressing piece 66 and second pressing piece 67) correspond to the first liner plate 64 and the second liner plate 65, respectively. During the pressing process of the briquette, one film to be butted is mainly covered on the first lining plate 64, and the other film to be butted is mainly covered on the second lining plate 65. However, an overlapping portion is required between the two films. More preferably, the first pressing block 66 and the second pressing block 67 move synchronously and are always on the same plane. Therefore, the two films can be ensured to be relatively flat.

Specifically, the butt joint operation method of the easy-to-joint slitting machine is as follows:

turning up the pedal cover 32 to open the pedal portion 3;

the pressing plate 62 is lowered by the driving part, so that the processed film segment and the film segment to be processed are respectively pressed on the first lining plate 64 and the second lining plate 65 by the pressing plate 62;

cutting the overlapped part of the processed film section and the film section to be processed by a cutting part 63;

after cutting, the waste material is moved out of the pedal part 3;

In a preferred embodiment, the easy-to-splice slitting machine may further include a cutter, an adsorption mechanism, and an adhesion mechanism. The cutter can be inserted into the base 31 when the step cover 32 is in the open state, and cut the front and rear films to be joined based on the cutting portion 63. The suction mechanism can cut the front and rear films to be connected in the cutting part 63, and then extend into the base 31, and suck out the waste materials formed by cutting. The bonding mechanism can stretch into the base 31 after the waste materials are sucked out by the suction mechanism, and butt joint is carried out on the front film and the rear film which need to be jointed through adhesive tapes. Therefore, the cutting machine, the adsorption mechanism and the bonding mechanism can realize the whole or partial automatic butt joint operation.

The embodiments in the present specification are described in a progressive manner, and the same or similar parts in the embodiments are referred to each other, and each embodiment focuses on differences from other embodiments. While the present application has been described by way of examples, those of ordinary skill in the art will appreciate that there are numerous variations and permutations of the present application that do not depart from the spirit of the present application and that the appended embodiments are intended to include such variations and permutations without departing from the present application.
