Description

Technical Field

[0001] This utility model relates to a grid steering mechanism for a film cutting and stacking machine. Background Technology

[0002] Currently, Chinese patent application CN202410154348.X discloses a film stacking device for an industrial film cutting and stacking machine. This device completes the film stacking operation through the cooperation of a swing feeding mechanism, an upper traction mechanism, a lower traction mechanism, and a clamping device. The swing feeding mechanism clamps the head of the grid and pulls it to rotate from a horizontal direction to a vertically downward direction. However, in actual use, it has been found that the swing feeding mechanism only clamps the head of the grid using left and right gripper components, which only clamps the left and right ends of the grid head. This results in insufficient clamping and a risk of loosening. Summary of the Invention

Detailed Implementation

[0042] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0043] like Figures 1-4 As shown, a grid turning mechanism for a film cutting and stacking machine includes a mounting frame 100, a rotating seat 200, a fixed clamping plate 1, a movable clamping plate 2, a clamping drive mechanism 300, and a rotation drive mechanism 400.

[0044] The rotating base 200 is rotatably connected to the mounting bracket 100;

[0045] The fixed clamping plate 1 is connected to the rotating seat 200, the movable clamping plate 2 is connected to the clamping drive mechanism 300, and a clamping gap 4 is provided between the fixed clamping plate 1 and the movable clamping plate 2 for the grid 3 to extend into.

[0046] The clamping drive mechanism 300 is connected to the rotating seat 200 and is used to drive the movable clamping plate 2 to move toward the fixed clamping plate 1 so that the fixed clamping plate 1 and the movable clamping plate 2 clamp the head of the grid 3 that extends into the clamping gap 4. The clamping drive mechanism 300 is also used to drive the movable clamping plate 2 to move away from the fixed clamping plate 1 to release the grid 3.

[0047] The rotary drive mechanism 400 is connected to the rotary seat 200 and is used to drive the rotary seat 200 to rotate, thereby causing the head of the grid 3, which is clamped by the fixed clamping plate 1 and the movable clamping plate 2, to turn.

[0048] Specifically, the mounting bracket 100 can be fixedly installed on the frame 5 of the film cutting and stacking machine. In the film cutting and stacking machine, the head of the grid 3 is first pulled into the clamping gap 4. Then, the clamping drive mechanism 300 drives the movable clamping plate 2 to move towards the fixed clamping plate 1 so that the fixed clamping plate 1 and the movable clamping plate 2 clamp the head of the grid 3 that extends into the clamping gap 4. Then, the rotation drive mechanism 400 drives the rotating seat 200 to rotate, thereby causing the head of the grid 3 clamped by the fixed clamping plate 1 and the movable clamping plate 2 to turn, so that the head of the grid 3 moves away from the attached... Figure 2 The horizontal direction in the middle turns to the attached Figure 3The grid 3 is vertically downward. Then, the traction mechanism in the film cutting and stacking machine clamps the head of the vertically downward-facing grid 3. The clamping drive mechanism 300 then drives the movable clamping plate 2 to move away from the fixed clamping plate 1 to release the grid 3. The traction mechanism in the film cutting and stacking machine then pulls the grid 3 downward. In this embodiment, the fixed clamping plate 1 and the movable clamping plate 2 can stably and reliably clamp the head of the grid 3, increasing the firmness of the clamping when the head of the grid 3 is turned, thus preventing the grid 3 from loosening after being clamped. The traction mechanism in the film cutting and stacking machine can, but is not limited to, the upper traction mechanism described in Chinese patent application CN202410154348.X.

[0049] like Figure 1 As shown, the fixed clamping plate 1 is provided with a fixed clamping end face 6 for abutting against the grid 3 when clamping it. The distance D between the rotation axis of the rotating seat 200 relative to the mounting frame 100 and the fixed clamping end face 6 is ≤10cm. Specifically, the swing feeding mechanism in the Chinese patent application with application number CN202410154348.X also has the following disadvantages: due to the long length of the left and right swing arms, the swing arm length is long when driving the grid 3 to turn and move, which leads to poor stability during swing. This makes it easy for the grid 3 to deviate after it turns and moves into place. Consequently, the grid 3 will not be uniform in position within the diaphragm after being stacked with the diaphragm, and there will be deviations, which will affect the quality and performance of the final product. In this embodiment, the head of the grid 3 is clamped onto the fixed clamping end face 6 in the fixed clamping plate 1 by the movable clamping plate 2. The distance between the rotation axis of the rotating seat 200 relative to the mounting frame 100 and the fixed clamping end face 6 is small. Therefore, the arm length of the rotation is greatly reduced when the grid 3 is turned, resulting in better stability during rotation and higher positional accuracy of the grid 3 after it is turned into position, eliminating positional deviation after the grid 3 is turned into position. In addition, because the arm length of the rotation is small and the stability during rotation is better in this embodiment, the rotation speed of the rotating seat 200 can be increased, thereby speeding up the production cycle and improving the speed and efficiency of the grid 3 head turning. In some embodiments, the distance D is preferably less than 5cm; in this embodiment, the distance D=0.

[0063] like Figures 1-4 As shown, the rotary drive mechanism 400 may further include a limiting block 16, a first elastic buffer 17, and a second elastic buffer 18.
