[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0030] Embodiment 1:
[0031] like Figure 1-5 As shown, a feeding balancing device of a laminating machine comprises two symmetrically arranged supporting plates 1.
[0032] Two groups of feeding components 3 are arranged on the opposite side of the two support plates 1, and a clamping component 4 is arranged on the outer wall of each group of feeding components 3. The clamping component 4 includes an axis 5 and a pressure roller 6. The pressure roller 6 is fixedly connected to a connecting component 7 through the axis 5. The connecting component 7 is fixed to the outer wall of the feeding component 3.
[0033] The adhesive film is placed between the two feeding assemblies 3, and then the two feeding assemblies 3 are started. The two feeding assemblies 3 rotate in opposite directions, driving the corresponding clamping assemblies 4 to rotate in opposite directions. When the two pressing rollers 6 both contact the adhesive film, the adhesive film is clamped and conveyed along with the feeding assemblies 3 until the two pressing rollers 6 in contact with the adhesive film move to the other end of the feeding assemblies 3, at which time the laminating operation is performed. After the laminating operation is completed, the feeding assemblies 3 are started again to continue conveying the adhesive film, so that the two pressing rollers 6 that clamped the adhesive film before are no longer in contact with the adhesive film, and at the same time, the two pressing rollers 6 at the other end of the feeding assemblies 3 begin to clamp the adhesive film for the next film conveying, and this reciprocating process is repeated until the laminating operation is completed.
[0034] The device is provided with two sets of feeding components 3 for reverse conveying. The two sets of feeding components 3 respectively drive two nip rollers 6 to move to clamp the rubber film and convey it for a distance. After the laminating operation is completed, the feeding components 3 are started again to use the other two nip rollers 6 to convey the rubber film for the next time, so that the nip rollers 6 are used to realize "clamping conveying" of the rubber film, avoiding the axial deviation of the rubber film and the roller during conveying due to roller conveying, thereby improving the stability of the film conveying.
[0035] In this embodiment, the feeding assembly 3 includes two fixed plates 11, a conveying roller 1 23 and a conveying roller 25, and the two fixed plates 11 are fixedly connected to the two supporting plates 1 respectively.
[0036] The conveying roller 1 23 and the conveying roller 2 25 are rotatably connected to the opposite sides of the two fixed plates 11 through the shaft 3 22 and the shaft 4 24 respectively, and a motor 2 is fixed to the side wall of one of the fixed plates 11 by bolts, and the output shaft of the motor 2 is fixedly connected to the shaft 3 22 through a coupling.
[0037] A plurality of auxiliary rollers 8 are arranged between the conveying roller 1 23 and the conveying roller 2 25. The auxiliary rollers 8 are rotatably connected to the opposite sides of the two fixed plates 11 through the shaft 2 9, and the conveying rollers 1 23, the conveying rollers 25 and the outer wall of the shaft 2 9 are driven by the same conveyor belt 10.
[0038] The motor 2 is started to drive the shaft 3 22 and the conveying roller 1 23 to rotate, and the conveying belt 10 is used to drive the auxiliary roller 8 and the conveying roller 2 25 to rotate, so that the conveying belt 10 and the connecting component 7 are used to drive the pressing roller 6 to move.
[0039] Embodiment 2:
[0040] A feeding balance device for a laminating machine. This embodiment makes the following improvements on the basis of embodiment 1: Figure 1-5 As shown:
[0041] The connecting assembly 7 includes two fixed blocks 12 and a moving block 16 , and the two fixed blocks 12 are fixedly connected to the outer wall of the conveyor belt 10 .
[0042] The movable block 16 is slidably fitted on the top of the fixed block 12 through the guide rod 13, and the shaft 5 is fixedly connected to the opposite side of the two movable blocks 16. The top of the fixed block 12 is fixedly connected with a threaded rod 17, and the outer wall of the threaded rod 17 is threadedly connected with an adjusting nut 14. The top of the adjusting nut 14 is contacted with a spring 15, and the other end of the spring 15 is fixedly connected to the bottom of the movable block 16.
[0043] The tops of the guide rod 13 and the threaded rod 17 are fixedly connected to the limiting block 21 and the limiting block 19 respectively. The inner side of the moving block 16 is provided with a limiting groove 18 and a limiting groove 20. The limiting block 19 and the limiting block 21 are slidably matched with the limiting groove 18 and the limiting groove 20 respectively.
[0044] In this embodiment, rotating the adjusting nut 14 can change the initial compression state of the spring 15, thereby changing the pressure of the nip roller 6 on the rubber film.
[0045] The device is provided with an adjusting nut 14 and a spring 15. The initial compression state of the spring 15 can be changed by rotating the adjusting nut 14. Thus, on the one hand, the pressure of the pressing roller 6 on the rubber film can be adjusted to avoid that too little pressure reduces the clamping effect on the rubber film, and at the same time, avoid that too much pressure causes excessive clamping and damages the rubber film. On the other hand, the wear of the pressing roller 6 can be compensated.
[0046] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
