Description

Technical Field

[0001] This utility model belongs to the field of winding machine technology, and in particular relates to a rubber roller for lithium battery winding machines. Background Technology

[0002] Lithium-ion batteries are widely used in consumer electronics, electric vehicles and other fields. The rollers of existing lithium battery winding machines are mainly made of rubber materials. Their surface characteristics, such as hardness, viscosity and wear resistance, directly affect the effective tension of the substrate and the bonding accuracy of the anode and cathode during the winding process.

[0003] The existing lithium battery winding machines use ordinary rubber rollers available on the market. Long-term use of these rollers can easily lead to aging and contamination of raw materials. In addition, the internal shafts of these rollers are mostly made of solid material, which increases manufacturing costs. Utility Model Content

[0004] This invention addresses the problems in existing technologies where prolonged use of rubber rollers easily leads to aging and contamination of raw materials, and the internal shafts of rubber rollers are mostly made of solid material, increasing manufacturing costs. The following technical solution is proposed:

[0005] A rubber roller for a lithium battery winding machine includes: a roller body, with end caps symmetrically arranged inside the roller body, each of the two end caps having a locking block integrally formed around its perimeter, a rotating shaft fixedly installed on one side of each of the two end caps, and a screw rotatably connected inside each of the two end caps. The end of the screw away from the end cap is threadedly connected to a threaded tube, and the end of the threaded tube away from the screw is fixedly connected to a movable frame. A groove is formed inside the roller body at a position corresponding to the movable frame, a locking strip is integrally formed on the outer surface of the movable frame, and a sliding groove is formed inside the roller body at a position corresponding to the locking strip.

[0006] As a preferred embodiment of the above technical solution, a slot is provided at the center of each of the two end caps, and a gasket is provided inside each of the two slots.

[0007] As a preferred embodiment of the above technical solution, the two gaskets are square in shape and are both made of stainless steel.

[0008] As a preferred embodiment of the above technical solution, the end of the screw near the end cap slides in contact with the outer surface of the gasket.

[0009] As a preferred embodiment of the above technical solution, the number of the movable frames is set to two, and the positions of the two movable frames are symmetrically distributed.

[0010] As a preferred embodiment of the above technical solution, a film layer is provided on the outer surface of the roller body, and the film layer is bonded to the outer surface of the roller body by an adhesive.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention utilizes a movable bracket installed inside the roller body. During the rotation of the screw, the bracket is moved closer to the end cover, thereby fixing the end cover inside the roller body. This facilitates the installation and removal of the end cover. Furthermore, the rotating shaft is fixedly installed on one side of the end cover, reducing the use of shaft material and saving costs. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example 1

[0021] This utility model provides a rubber roller for a lithium battery winding machine, such as... Figures 1 to 5As shown, the roller body 1 includes end caps 2 symmetrically arranged inside the roller body 1. Each end cap 2 has a locking block 21 integrally formed around its perimeter. A rotating shaft 3 is fixedly installed on one side of each end cap 2. A screw 5 is rotatably connected inside each end cap 2. The end of the screw 5 away from the end cap 2 is connected to a threaded tube 6 via a thread. The end of the threaded tube 6 away from the screw 5 is fixedly connected to a movable frame 7. A groove 71 is formed inside the roller body 1 at the position corresponding to the movable frame 7. A locking strip 73 is integrally formed on the outer surface of the movable frame 7. A sliding groove 72 is formed inside the roller body 1 at the position corresponding to the locking strip 73. By rotating the screw 5, in conjunction with the action of the threaded tube 6, the screw 5 and the movable frame 7 move simultaneously toward the end cap 2. Due to the setting of the groove 71 inside the roller body 1, when the movable frame 7 moves to the end position of the groove 71, the closest distance between one end of the screw 5 and one side of the end cap 2 is 0.5 cm. A film layer 4 is provided on the outer surface of the roller body 1. The film layer 4 is bonded to the outer surface of the roller body 1 by an adhesive.

[0022] like Figure 5 As shown, a slot 8 is provided at the center of each of the two end caps 2. A gasket 81 is provided inside each of the two slots 8. The two gaskets 81 are square in shape and made of stainless steel. The thickness of the two gaskets 81 is 0.5cm. By rotating the screw 5, the end of the screw 5 that is close to the end cap 2 slides into contact with the outer surface of the gasket 81. With the setting of the gasket 81, the friction between the screw 5 and the end cap 2 is increased, which improves the stability of the screw 5 when the roller 1 rotates and prevents the screw 5 from deflecting.

[0023] like Figure 2 As shown, there are two movable frames 7 in total, and the positions of the two movable frames 7 are symmetrically distributed. By symmetrically setting the movable frames 7, the centrifugal force on the entire roller 1 is evenly distributed when the roller 1 rotates, which improves the stability of the roller 1 when it rotates and prevents it from shaking.

[0024] Working principle: The end cap 2 is engaged with the inside of the roller body 1 by the locking block 21. Then, the screw 5 passes through the end cap 2 and the gasket 81, so that one end of the screw 5 is inserted into the inside of the threaded tube 6. Rotating the screw 5, in conjunction with the action of the threaded tube 6, causes the screw 5 and the moving frame 7 to move towards the end cap 2. When the moving frame 7 moves to the end position of the groove 71 and can no longer move, the screw 5 is in contact with the outer surface of the gasket 81, thereby fixing the end cap 2 inside the roller body 1. This facilitates the installation and removal of the roller body 1. At the same time, the rotating shaft 3 is no longer provided inside the roller body 1, reducing the use of material for the rotating shaft 3 and saving costs.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
