Description

Technical Field

[0001] The invention belongs to the technical field of lithium battery industry and slitting equipment with variable forms, and specifically relates to a pressing wheel mechanism with adjustable pressing force used on a slitting machine. Background Art

[0002] A slitting machine is a mechanical device specially used for cutting film materials. Its main function is to slit wide films into products of specific width for further processing or use. In the lithium battery industry, different materials (such as diaphragms, copper foils, and aluminum foils, etc.) need to be cut. Specifically, the edge thickness is left at the edges on both sides to compress the materials. After cutting, the edge materials are collected under negative pressure. The pressing mechanism needs to meet the following functions: 1. When changing products, the pressing wheel is easy to adjust to free up space for practical operation; 2. Since the width and thickness of the materials are different, the pressing wheel structure needs to be designed to be movable in the axial direction of the roller body and rotatable on the fixed axis of the pressing wheel. It is locked after being adjusted to the specified position, that is, the position in the axial direction of the roller surface can be adjusted arbitrarily to meet the production of products of different widths; 3. The materials need to be pressed during the slitting production process, and the pressing wheel always maintains a constant pressing force on the materials to ensure that the incision position is flat; 4. For different products, the pressing force of the pressing wheel can be adjusted to ensure that the cut material is in a pressed state between the pressing wheel and the roller surface. Different materials need to be pressed with different pressing forces to meet the pressing requirements of materials of different widths, thicknesses, and different pressing forces.

[0021] See also Figure 1 As shown, the pressure wheel mechanism with adjustable pressing force for the slitting machine of the present invention comprises a base, a guide rod 1 and a pressure wheel 2, wherein the guide rod 1 is arranged at one side of the transmission roller 3, the axis of the guide rod 1 is parallel to the axis of the transmission roller 3, the pressure wheel 2 is arranged on the base, the base can move left and right along the guide rod 1 and can be stopped at any position on the guide rod 1. A pressing force adjusting device is arranged on the base, and the pressure wheel 2 can rotate with the transmission roller 3 through the pressing force adjusting device to achieve pressing.

[0022] Furthermore, the base includes a fixed seat 8 and a connecting seat 9. The fixed seat 8 is sleeved on the guide rod 1. The pressure wheel 2 is rotatably connected to the fixed seat 8 through the connecting seat 9. The connecting seat 9 can rotate relative to the fixed seat 8.

[0023] In a preferred embodiment, the clamping force adjustment device includes a first support 4, a tightening screw 5, a second support 6 and a spring sheet 7. The first support 4 is arranged on a fixed seat 8, the second support 6 is arranged on a connecting seat 9, the tightening screw 5 is rotatably connected to the first support 4, the spring sheet 7 is arranged on the second support 6, the pressing wheel 2 and the spring sheet 7 are both located on the rotational movement path of the tightening screw 5, and the tightening screw 5 is adjusted to deform the spring sheet 7, so that the pressing wheel 2 generates a torque moving toward the roller surface of the transmission roller 3, thereby realizing the clamping function. Even when the thickness of the edge material is different, the pressing wheel 2 always maintains a clamping state. The pressing wheel 2 is preferably a rubber wheel. After the clamping function is adjusted, it is fixed by the clamping screw 5. Specifically, the pressure wheel 2 can rotate around the axis of the guide rod 1. After the pressure wheel 2 is pressed against the material, the spring sheet 7 is deformed by rotating the clamping screw 5. Since the connecting seat 9 can rotate relative to the fixing seat 8, the pressure wheel 2 is driven to rotate toward the transmission roller 3, thereby achieving the compression of the material, and the compression force is constant. It is easy to understand that if there are different requirements for the compression force, the spring sheet 7 can be adjusted to achieve the compression force adjustment.

[0024] See also Figure 2 As shown, the fixing seat 8 is cylindrical, and an arc-shaped lock buckle 10 is provided along the outer circumference of the fixing seat 8. The arc-shaped lock buckle 10 is provided with a first lock hole, and the fixing seat 8 is provided with a second lock hole at a position corresponding to the first lock hole. The first lock hole and the second lock hole are relatively locked by a locking screw 11. When the locking screw 11 is loosened, the fixing seat 8 can drive the pressing wheel 2 to slide on the guide rod 1, thereby realizing the cutting of products of different widths.

[0025] When working:

[0026] a. Before threading the material, loosen the locking screw 11 and rotate the fixing seat 8 to separate the pressing wheel 2 from the roller surface. The separation distance should be based on the convenience of operation.

[0027] b. After the material passes through, adjust the position of the pressing wheel 2 on the guide rod 1 according to the actual width of the material and the mold path, so as to ensure that the pressing wheel 2 contacts the material as much as possible;

[0028] c. After determining the positions of the left and right pressing wheels, rotate the fixing seat 8 to make the pressing wheel 2 fit the material, and then lock it with the locking screw 11;

[0029] d. By adjusting the tightening screw 5, the spring sheet 7 is deformed, and at the same time the connecting seat 9 rotates relative to the fixing seat 8, so that the pressing wheel 2 rotates toward the roller surface to achieve the clamping function.

[0030] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
