AI Technical Summary
In the existing lithium battery industry slitting equipment, the jumping accuracy of the material roll mandrel is difficult to reach high standards, which leads to frequent jumping of the material roll during the operation of the equipment, affecting the tension stability of the product during the operation. There is a back gap in the mechanical transmission structure of the adjustment device, which leads to high-frequency vibration of the roller surface and affects the stability of the equipment.
A roller adjustment mechanism without back gap is designed. By setting a fixed plate, guide rail and bearing seat at both ends of the roller body, and using a driving adjustment assembly and a spring assembly, the back gap in the mechanical adjustment structure at both ends of the roller is eliminated, ensuring that the roller surface rotates stably when the external tension changes.
By eliminating the back gap at both ends of the roller, the roller surface jumping caused by tension fluctuations is avoided, the stability of the equipment is ensured during operation, and the plastic deformation of the product is prevented due to jumping and tension fluctuations.

Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of metal foil slitting in the lithium battery industry, and in particular relates to a backlash-free roller adjustment mechanism and slitting equipment. Background Art
[0002] The existing slitting equipment in the lithium battery industry has difficulty in achieving high runout accuracy for the core shaft of the material roll of the slitting product, which causes the material roll to run significantly and frequently during the unwinding process of the equipment, thereby affecting the tension of the product during operation. At present, there is backlash in the mechanical transmission structure of the adjustment device in the industry. Backlash refers to a performance parameter of the reducer. The backlash in the reducer, that is, the return clearance: when the input end is fixed and the output end rotates clockwise and counterclockwise to produce a rated torque of ±2% at the output end, there is a small angular displacement at the output end of the reducer. This angular displacement is the return clearance, and the unit is arcmin. The lower this value, the better. Due to the backlash in the mechanical structure of the adjustment device, the change in tension during product operation will cause the roller to vibrate at high frequency, affecting the stability of the equipment. Summary of the invention
[0003] In view of this, an object of the present invention is to provide a roller adjustment mechanism and a slitting device without backlash to solve the deficiencies in the prior art.
[0004] In order to achieve the above object, the present invention is achieved through the following technical solutions:

The guide rail is arranged vertically, and one end face of the bearing seat is rotatably connected to the end of the roller body, and the other end face is slidably connected to the guide rail. A driving adjustment component is provided above the bearing seat, and a spring component is provided below. The driving adjustment component adjusts and drives the bearing seat to slide along the guide rail. The spring component is provided on the sliding path of the bearing seat and generates a tightening force on the bearing seat.
[0006] As described in the backlash-free roller adjustment mechanism, wherein the driving adjustment component includes an adjustment fixing block and an adjustment handwheel and an adjustment screw connected in sequence, the adjustment fixing block is fixed to the top surface of the fixed plate, and the adjustment fixing block is provided with a screw hole suitable for the adjustment screw, and the adjustment screw passes through the screw hole and then is connected to the top surface of the bearing seat.
[0007] As described in the backlash-free roller adjustment mechanism, wherein the spring assembly includes a fixed seat and a spring body, the lower end of the spring body is fixed on the fixed seat, and the upper end is connected to a push rod, and the upper end of the push rod is connected to the bottom surface of the bearing seat.
[0008] As described in the backlash-free roller adjustment mechanism, a locking and limiting assembly is provided on one side of the bearing seat to keep the position of the bearing seat on the guide rail unchanged.

[0010] On the other hand, a slitting device is provided, which includes a backlash-free roller adjustment mechanism as described in any one of the items.
[0011] The beneficial effects of the technical solution of the present invention are:
[0012] The spring generates pre-pressure on the mechanism to eliminate the backlash in the mechanical adjustment structure at both ends of the roller, so that the roller surface can rotate stably when the external tension keeps changing, avoiding plastic deformation of the product on the roller surface due to vibration and tension fluctuation, thus achieving the purpose of eliminating roller surface vibration caused by tension fluctuation during equipment operation.

The adjustment screw 7 passes through the screw hole and is connected to the top surface of the bearing seat 4. By rotating the adjustment hand wheel 6, the adjustment screw 7 moves downward as shown in the figure to push the bearing seat 4 to slide downward along the guide rail 3 to complete the displacement control.
[0022] The guide rails 3 may appear in pairs.
[0023] The spring assembly includes a fixing seat 8 and a spring body 9 . The lower end of the spring body 9 is fixed on the fixing seat 8 , and the upper end is connected to a push rod 10 . The upper end of the push rod 10 is connected to the bottom surface of the bearing seat 4 .
