In the above process, the part of the glue material of the second composite coiled material 5 near the edge part also has a moving trend towards the center line of the second composite coiled material 5, and compared with the pressing roller with a longer length, in this embodiment, only the glue material of the position of the second composite coiled material 5 near the edge part has an outward moving condition, and the glue material on the inner side of the pressing roller 22 at the front end basically moves inwards under the stop action of the pressing roller 22.
The length of the laminating roller 22 at the end is greater than the width of the second composite web 5 to achieve a full lamination of the second composite web 5 after inward polymerization, and a small amount of glue that is excessively polymerized around the center line of the second composite web 5 can be pushed out or flattened, and the laminating roller 22 at the end functions similarly to the forming press roller 23.
As shown in fig. 6 and 8, the pressing assembly 6 includes a mounting frame 21 disposed above and below the second composite web 5, and a plurality of movable press rolls 26 mounted on the mounting frame 21, the length direction of the movable press rolls 26 is parallel to the transport direction of the second composite web 5, a pair of forming press rolls 23 are disposed at the downstream end of the movable press rolls 26, the second composite web 5 is disposed between the movable press rolls 26 and between the forming press rolls 23, and the gap width between the movable press rolls 26 is the thickness of the second composite web 5 formed.
Likewise, the forming press roller 23 is capable of pressing the second composite web 5 after polymerization, except that the movable press roller 26 is capable of pushing the corresponding glue material inward along the width direction of the second composite web 5, the position of the pressing roller 22 is fixed, the relative movement of the second composite web 5 and the pressing roller 22 realizes the pressing, the direction of the relative movement is along the direction of transportation of the second composite web 5, and the movable press roller 26 is operated along the width direction of the second composite web 5, so that the pressing is realized by the relative movement.
The forming press roller 23 adopts the same pressing mode as that of the first embodiment, the first embodiment can be regarded as active pressing (the second composite coiled material 5 actively moves to realize pressing), the second embodiment can be regarded as passive pressing, the movable press roller 26 moves to press the second composite coiled material 5, the position of the pressed second composite coiled material 5 needs to be unchanged in the process, and the second embodiment also has the corresponding active pressing mode of the forming press roller 23, so the second embodiment can be regarded as a pressing mode of combining the passive and the active.
With the area around the center line of the second composite coiled material 5 as a boundary, two movable press rolls 26 are arranged, and the two sides of the center line of the second composite coiled material 5 are respectively pressed from outside to inside, so that the distance between the movable press rolls 26 is fixed along the width direction of the second composite coiled material 5 and is larger than the width of the second composite coiled material 5.
Because the length direction of the movable press roller 26 is consistent with the transportation direction of the second composite coiled material 5, the movable press roller 26 is arranged above the second composite coiled material 5 in transportation to generate dynamic friction with the second composite coiled material 5, so that the surface of the second composite coiled material 5 is worn, and the position of the movable press roller 26 is limited so that the movable press roller 26 can not cause a stop to the second composite coiled material 5 in the non-pressing process.
The movable press roller 26 is driven to move so as to drive the movable press roller 26 to press along the width direction of the second composite coiled material 5, a movable seat 27 is arranged on the mounting frame 21, mounting shafts 28 are symmetrically arranged on the movable seat 27, the movable press roller 26 is coaxially connected with the mounting shafts 28, a threaded screw rod 29 is arranged on the movable seat 27, a driving motor 210 is arranged on the mounting frame 21, and the threaded screw rod 29 is connected to the output end of the driving motor 210.
The driving motor 210 drives the threaded screw rod 29 to rotate, and under the rotation action of the threaded screw rod 29, the movable seat 27 and the movable press roller 26 can be driven to move left or right, and the position of the left or right movement should be limited by the position of the bottom of the movable press roller 26 contacting with the second composite coiled material 5 at least reaching the position of the center line of the second composite coiled material 5.
The second composite web 5 is required to be kept from being transported in the outside-in pressing manner in the second embodiment, and the transportation state of the whole second composite web 5 is unchanged, for which purpose the present invention provides a transportation roller line 7, and the transportation roller line 7 adopts the following preferred embodiment, as shown in fig. 4, wherein the transportation roller line 7 comprises a first roller group 71, a second roller group 72 and a third roller group 73 which are sequentially arranged along the transportation direction of the second composite web 5, the first roller group 71, the second roller group 72 and the third roller group 73 are arranged between the pre-cooling and the mounting frame 21, the second composite web 5 passes through the first roller group 71, the second roller group 72 and the third roller group 73, the positions of the first roller group 71 and the third roller group 73 are fixed, and the second roller group 72 moves along the width direction of the second composite web 5.
The driving states of the first roller set 71 and the third roller set 73 are adjustable, that is, the first roller set 71 and the third roller set 73 can drive the second composite coiled material 5 to transport forward, and can stop driving to stop transporting the second composite coiled material 5 at the corresponding position.
In order to ensure the tension of the second composite web 5, the present invention is also designed such that a driving cylinder 74 is provided on the second roller group 72, and the driving end of the driving cylinder 74 is provided along the width direction of the second composite web 5.
The second roller group 72 can be operated by the driving cylinder 74 so that the second composite web 5 between the first roller group 71 and the second roller group 72 becomes longer, and the downstream end of the third roller group 73 is suitably brought to a stopped conveyance state.
That is, when the movable press roller 26 is pressed actively, the driving is stopped from the third roller group 73 so that the second composite web 5 at the rear end of the third roller group 73 is in a stopped transportation state, at this time, the transportation state of the first roller group 73 is unchanged, the continuous transportation of the front portion of the second composite web 5 is ensured, the second roller group 72 moves along the width direction of the second composite web 5, the length of the second composite web 5 between the first roller group 71 and the third roller group 73 is lengthened, the lengthened second composite web 5 can be always in a stretched state by the second roller group 72, and after the pressing of the second composite web 5 is completed, the third roller group 73 can be run in an accelerated manner so that the second composite web 5 between the first roller group 71 and the third roller group 73 is shortened to restore the initial state.
In the above embodiment, the length of the movable platen roller 26 needs to be set long enough to enable the second composite web 5 between the first roller group 71 and the third roller group 73 to be reset to a state of being initially in line just when a certain section of the second composite web 5 is being nipped and moved away from the movable platen roller 26, and the next section of the second composite web 5 just reaches the movable platen roller 26 under the driving control of the first roller group 71 and the third roller group 73, so that the stop transportation and the nip of the next stage can be performed.
