[0002] The lithium battery bell jar type liquid injection machine is a special liquid injection device used in the production of lithium batteries, mainly used for the electrolyte injection process. In the lithium battery bell jar type liquid injection machine, roller supports and transmission jigs are usually installed on the jig placement platform inside the bell jar.

[0003] Some existing traditional jig placement platforms inside the bell jar generally use roller jigs without resistance, which will change their positions due to the lifting of the bell jar and the internal gas flow, thus affecting the positioning position when the jig is removed from the bell jar for the second time. In severe cases where the jig position deviation is large, the jig will even be directly damaged when pressed by the bell jar. Using rollers directly with external springs, their large volume cannot effectively utilize the internal space of the bell jar. Therefore, a damping roller is proposed to solve the above problems. Summary of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 3 As shown in the figure, an embodiment provided by the present utility model: a damping roller includes a placing platform 1 for supporting the fixture and assisting the forward and backward movement of the fixture. The upper part of the placing platform 1 is provided with a damping roller assembly for assisting the movement of the fixture. The damping roller assembly includes a wheel body 2, which is the main body of the damping roller. The middle part of the wheel body 2 is penetrated and rotatably connected with a fixed shaft 3 for cooperating with the installation of the wheel body 2 and the mounting plate 11. The middle part of the fixed shaft 3 is provided with a ring groove 31 for cooperating with the connection of the ball plunger 5. Snap rings 4 are arranged on both the left and right sides of the wheel body 2 for cooperating with fixing the position of the wheel body 2. The upper part of the wheel body 2 is provided with a ball plunger 5. By adjusting the position of the hollow column 51 of the ball plunger 5, resistance can be applied to the fixed shaft 3 through the ball 53, thereby changing the resistance of the roller.

[0032] Furthermore, the placing platform 1 includes a mounting plate 11 and the number is multiple, which are used to form the placing platform 1 for cooperating with the installation of the damping roller. The top of the mounting plate 11 is provided with multiple mounting grooves 12, and the damping roller assembly is installed inside.

[0033] As Figure 3 - Figure 5As shown in the figure, a fixing opening 21 is provided in the middle of the wheel body 2 for cooperating with the connection of the fixing shaft 3. The fixing shaft 3 is movably connected thereto. A fixing groove 23 is provided in the upper part of the wheel body 2 for cooperating with the connection of a plurality of limiting rings 24. The limiting rings 24 at different heights have different colors, so as to facilitate determining the position adjustment condition of the hollow column 51. An auxiliary groove 22 is provided in the lower part of the fixing groove 23 for cooperating with the position adjustment of the hollow column 51. A plurality of limiting rings 24 are fixedly connected to the inner wall of the fixing groove 23, and the diameter of the opening in the middle thereof is adapted to the diameter of the hollow column 51. Auxiliary openings 241 are provided on both the front and rear sides of the limiting ring 24 for cooperating with the movement of the clamping block 512. Clamping grooves 242 are provided on both the left and right parts of the lower side of the limiting ring 24 for cooperating with the fixing of the clamping block 512.

[0034] Furthermore, the ball head plunger 5 includes a hollow column 51 for connecting various components. The hollow column 51 is movably connected to the auxiliary groove 22. A connecting column 52 is slidably connected to the inner wall of the hollow column 51 for cooperating with the hollow column 51. A ball 53 is movably connected to the lower part of the connecting column 52 for contacting the fixing shaft 3, and it fits the inner wall of the ring groove 31. A spring 54 is fixedly connected between the connecting column 52 and the hollow column 51 for cooperating with the hollow column 51 and the connecting column 52 to adjust the resistance when the ball 53 contacts the fixing shaft 3. A control groove 511 is provided at the top of the hollow column 51 for cooperating with the connection of an adjusting tool. The adjusting tool can be a screwdriver or other tools. Clamping blocks 512 are fixedly connected to both the left and right sides of the upper part of the outer wall of the hollow column 51 for cooperating with the limiting ring 24 to control the position of the hollow column 51 to cooperate with restricting the resistance of the roller. The clamping block 512 is movably connected to the clamping groove 242.

[0035] Working principle: When in use, insert the adjusting tool into the control groove 511 to slightly press down the hollow column 51, so that the clamping block 512 disengages from the clamping groove 242. Then rotate the adjusting tool, which will drive the hollow column 51 to rotate accordingly. When the clamping block 512 on the outer wall of the hollow column 51 rotates to the auxiliary opening 241, according to the requirement, if it is necessary to reduce the resistance, slightly reduce the pressure applied to the hollow column 51, so that the spring 54 can be restored to a certain extent, and the spring 54 pushes the hollow column 51 to move upward. When it is necessary to increase the resistance, increase the force applied to the hollow column 51 to press the hollow column 51 towards the fixing shaft 3, so as to further compress the spring 54. The spring 54 will then apply a force to the connecting column 52, thereby increasing the resistance between the ball 53 and the fixing shaft 3. When reaching the lower part of the limiting ring 24 at the appropriate height, use the adjusting tool to rotate the hollow column 51 to drive the clamping block 512 to rotate 90 degrees, so that the clamping block 512 comes to the lower part of the clamping groove 242. Then release the hollow column 51, and the spring 54 will apply an upward force to the hollow column 51, so that the clamping block 512 is clamped into the clamping groove 242, thereby fixing the position of the hollow column 51 to complete the adjustment of the resistance of the damping roller assembly.
