Description

Technical Field

[0001] The utility model relates to the technical field of pole piece manufacturing equipment, in particular to a thermal composite device. Background Art

[0002] The thermal composite mechanism will lift the composite roller through the cylinder to prevent the diaphragm and the pole piece from being embossed. Due to the uncertainty factors, the shutdown operation is too frequent, and the cylinder lifts the composite roller many times. In addition, the structural design of the thermal composite mechanism is unreasonable. After the cylinder lifts the composite roller, the position accuracy between the upper and lower composite rollers is affected. After the thermal composite mechanism resumes normal operation, wrinkles will appear on the surface of the diaphragm behind the composite pole piece. In addition, every time the composite roller is installed, it is difficult to ensure the parallelism between the upper and lower composite rollers. There is a certain offset between the two composite rollers, and the pole piece will deviate, resulting in poor composite effect. The defective material strip will be transferred to the subsequent station, and the product defect rate will increase. Utility Model Content

In this way, both ends of the first pressing roller 2 can be fine-tuned in the horizontal direction, and can guide the lifting and lowering of the mounting frame. At the same time, the installation of the mounting plate 11 can provide a mounting base for the first pressing roller 2 on the one hand, and on the other hand, its cooperation with the frame 1 is also conducive to the arrangement of the first guide mechanism 4.

[0040] The first guide mechanism 4 of this embodiment has a specific structure. Figures 1 to 4 The first guide mechanism 4 includes guide plates 41 disposed at both ends of each mounting plate 11 in the horizontal direction, that is, guide plates 41 are respectively disposed at both ends of each mounting plate 11 in the horizontal direction. Each guide plate 41 is detachably connected to the mounting plate 11, and a guide end surface 410 is disposed on one side of each guide plate 41 close to the frame 1. The guide end surface 410 is disposed on the guide plate 41, and the guide plate 41 is detachably connected to the mounting plate 11, which can facilitate the preparation of the mounting plate 11 on the one hand, and facilitate the disassembly and assembly of the guide plate 41 on the other hand, so that the first guide mechanism 4 has a simple structure and is more convenient to assemble and replace.

[0041] As a preferred embodiment, in this embodiment, the guide plate 41 has a first plate body 411 connected to the mounting plate 11, and a second plate body 412 connected to the end of the first plate body 411 and extending toward one side of the first plate body 412.

In specific implementation, the first plate body 411 and the second plate body 412 are connected in an L-shape, and a first connecting hole 4110 is provided on the first plate body 411. The first plate body 411 is fixedly connected to the mounting plate 11 by a threaded connector, such as a bolt or a screw, that is inserted through the first connecting hole 4110.

And as a preference, the long hole 421 and the second connecting hole 422 are both arranged at intervals, and the long hole 421 and the second connecting hole 422 are arranged alternately, so that the length of the follower plate 42 is set shorter, making the structure more compact.

[0044] Furthermore, in a specific implementation, each first bearing 52 can be fixed on the follower plate 42 by bolts or screws installed in the second connection holes 422.

When adjusting the horizontal position of the first bearing 52, the follower plate 42 is pushed by external force to move horizontally relative to the frame 1. At this time, the long hole 421 moves relative to the connecting member and drives the first rolling body on the follower plate 42 to move horizontally, thereby adjusting the horizontal position of the first bearing 52. The horizontal direction is also Figure 2 Directions shown in .

[0045] To facilitate the movement of the follower plate 42, in this embodiment, a tightening member for pushing the follower plate 42 to move is provided on the frame 1.

In addition, the detachable connection of the limit plate 43 can facilitate the arrangement and installation of the tightening member, and also facilitate the installation and replacement of the first guide mechanism 4 on the frame 1.

In addition, the axis of each second bearing 53 is arranged perpendicular to the axis of the first pressure roller 2. The threaded connecting member mentioned may be, for example, a bolt or a screw.

[0050] In addition, in the thermal composite device of this embodiment, the first pressing rollers 2 and the second pressing rollers 3 are arranged in multiple groups at intervals along the material conveying path. And corresponding to the first pressing rollers 2 in each group, a first guide mechanism 4 is provided between the frame 1 and the mounting frame, so that not only the relative positions of the first pressing rollers 2 and the second pressing rollers 3 in each group can be adjusted, but also the parallelism of the center planes of the first pressing rollers 2 and the second pressing rollers 3 between two adjacent groups can be adjusted, which is conducive to improving the composite efficiency and composite quality.

[0051] At the same time, as a preferred embodiment, in the thermal composite device of this embodiment, corresponding to the first pressing roller 2 in each group, a second guide mechanism 5 is also provided between the mounting plate 11 and the frame 1.

[0052] The thermal composite device of this embodiment can ensure the accuracy of the first roller 2 during the lifting and lowering process by setting the first guide mechanism 4 and the second guide mechanism 5, and is conducive to eliminating the problem of pole piece or diaphragm wrinkles.
