Description

TECHNICAL FIELD

[0001] The utility model relates to battery production technical field, concretely relates to a kind of active edge pulling flattening device. BACKGROUND

[0002] The base material such as pole piece and film of lithium battery will generally go through unwinding-coating-drying-correcting-pulling-winding processes in the production process, and the base material will curl and deform in the drying process under the action of thermal stress and temperature gradient, so a flattening device needs to be set at the position of the inlet and outlet of drying oven to flatten the base material, otherwise wrinkles and other adverse problems will be caused.

[0003] The existing flattening device generally adopts two driven roller mechanisms arranged in an eight-shaped manner, and the driven roller mechanism generally includes two driven rollers arranged oppositely in an up-down manner. When flattening the base material, the two driven rollers of the two driven roller mechanisms clamp the two sides of the base material respectively to generate friction between the driven rollers and the base material, and the friction is static friction. Under the action of the static friction, the two driven rollers of the two driven roller mechanisms can pull the base material to move to both sides respectively, so as to flatten the base material.

[0004] Since the static friction will change with the change of external force, when the base material appears unstable running in the drying process due to curling, drumming and shaking, the static friction between the driven rollers and the base material will change, so it is impossible to ensure that the static friction between the two driven rollers of the two driven roller mechanisms and the base material is consistent. When the two driven rollers of the two driven roller mechanisms pull the base material to move to both sides respectively, the base material will often appear deviation. SUMMARY

[0032] The active roller mechanism 40 comprises a supporting seat 41, a moving driving member 42, two rotating driving members 43 arranged up and down, and two active rollers 44 arranged up and down.

[0033] The support base 41 of the two active roller mechanisms 40 is connected with the angle adjusting mechanism 50 at the top end of the two mounting bases 30. The moving driving member 42 is arranged at one side of the support base 41 (i.e. the side of the support base 41 close to the center of the mounting shaft), above the corresponding mounting base 30 and partially protruding from the end of the corresponding mounting base 30 close to the center of the mounting shaft. The two rotating driving members 43 are arranged between the moving driving member 42 and the center of the mounting shaft, and are connected with the upper end and the lower end of the moving driving member 42 respectively. The two active rollers 44 are correspondingly arranged with the two rotating driving members 43, between the corresponding rotating driving member 43 and the center of the mounting shaft, and are connected with the output end of the corresponding rotating driving member 43, so that the rotating driving member 43 drives the corresponding active roller 44 to rotate. The moving driving member 42 drives the two rotating driving members 43 to move close to or away from each other, so as to drive the two active rollers 44 to move close to or away from each other. The angle adjusting mechanism 50 drives the support base 41 of the corresponding active roller mechanism 40 to rotate, so as to drive the moving driving member 42, the two rotating driving members 43 and the two active rollers 44 of the corresponding active roller mechanism 40 to rotate.

[0034] In the embodiment, the two rotating driving members 43 are connected with the upper end and the lower end of the moving driving member 42 through the two mounting plates 45, and the moving driving member 42 drives the two rotating driving members 43 to move close to or away from each other through the two mounting plates 45.

The rotating driving member 43 is arranged between the vertical part of the corresponding mounting plate 45 and the moving driving member 42, and is arranged at the side of the vertical part of the corresponding mounting plate 45 close to the moving driving member 42. The output end of the rotating driving member 43 passes through the hole of the vertical part of the corresponding mounting plate 45 and is connected with the corresponding active roller 44.

[0035] Through the above structure, in actual application, the base material 100 is carried along the front-to-back direction, first, the two rotating driving members 43 and the two driving rollers 44 are driven to move away from each other by the moving driving members 42 of the two driving roller mechanisms 40, so that a space is formed between the two driving rollers 44. After the base material 100 passes through the space between the two driving rollers 44 of the two driving roller mechanisms 40, the left driving roller mechanism 40 is driven to rotate in the counterclockwise direction by the angle adjusting mechanism 50 at the top of the left mounting seat 30, and the right driving roller mechanism 40 is driven to rotate in the clockwise direction by the angle adjusting mechanism 50 at the top of the right mounting seat 30, so that the two driving roller mechanisms 40 are in the shape of a splay, and an angle is formed between the axial direction of the driving roller 44 and the carrying direction of the base material 100. Then, the two rotating driving members 43 and the two driving rollers 44 are driven to move close to each other by the moving driving members 42 of the two driving roller mechanisms 40, so that the two driving rollers 44 of the two driving roller mechanisms 40 clamp the two sides of the base material 100 respectively. Then, the two driving rollers 44 are driven to rotate in the counterclockwise direction by the two rotating driving members 43 of the two driving roller mechanisms 40 respectively, and at this time, the friction between the two driving rollers 44 of the two driving roller mechanisms 40 and the base material 100 is generated respectively, which is sliding friction. Under the action of the sliding friction, the base material 100 is pulled to move to the two sides by the two driving rollers 44 of the two driving roller mechanisms 40 respectively, so that the base material 100 is flattened.

[0043] In the embodiment, the two mounting shafts are a first mounting shaft 20a and a second mounting shaft 20b, which are arranged side by side in front and back. The mounting seat 30 is provided with a first through hole 31a and a second through hole 31b corresponding to the first mounting shaft 20a and the second mounting shaft 20b respectively, and the mounting seat 30 is sleeved on the outer periphery of the first mounting shaft 20a and the second mounting shaft 20b through the first through hole 31a and the second through hole 31b, so that the mounting seat 30 can move left and right along the first mounting shaft 20a and the second mounting shaft 20b. The left and right movement of the mounting seat 30 can drive the angle adjusting mechanism 50 and the corresponding driving roller mechanism 40 to move left and right. Through the left and right movement of the two driving roller mechanisms 40, the distance between the two driving roller mechanisms 40 can be adjusted, so that the base material 100 of different widths can be adapted.

When the width of the base material 100 is relatively narrow and the distance between the two driving roller mechanisms 40 needs to be adjusted, the driving roller mechanism 40 on the left is moved to the right to a predetermined position, and the driving roller mechanism 40 on the right is moved to the left to a predetermined position, so that the distance between the two driving roller mechanisms 40 is reduced. Moreover, the mounting seat 30 is sleeved on the outer periphery of the two mounting shafts, which can improve the stability of the movement of the mounting seat 30, and further improve the stability of the movement of the angle adjusting mechanism 50 and the corresponding driving roller mechanism 40.

The two second handles and the two third handles 72 can fix the mounting base 30 on the first mounting shaft 20a and the second mounting shaft 20b, so as to prevent the mounting base 30 from moving, thereby preventing the corresponding driving roller mechanism 40 from moving.
