[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is a contact part embodiment of the utility model, not all embodiments.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please refer to the attached Figure 1-4 , this embodiment provides a pole piece anti-flying belt device 10, which is used for preventing the pole piece from flying on the conveying roller 20. The conveying roller 20 is generally arranged along the tape running direction of the pole piece 60, and is used to transport the pole piece 60. The pole piece anti-flying belt device 10 includes a moving component 11 and a pressing roller 12. The moving component 11 is used to drive the pressing roller 12 to move. The moving component 11 is connected to the pressing roller 12 by transmission to drive the pressing roller 12 to move back and forth in the direction of the conveying roller 20. Specifically, the moving component 11 can be a cylinder, a screw guide rail, a linear moving module, a gear rack, etc. This embodiment is not limited here, and it only needs to drive the pressing roller 12 to move. Exemplarily, the moving component 11 can be a cylinder, and the driving end of the cylinder is respectively connected to the two ends of the pressing roller 12 by transmission, so as to drive the pressing roller 12 to move in the direction of the conveying roller 20, thereby pressing the pole piece 60 on the pressing roller 12. It can be understood that the connection method can also be that one end of the pressing roller 12 is connected to a driving mechanism such as a cylinder or a screw rod, and the other end is connected to a mechanism such as a guide rail slider.

[0032] The pressing roller 12 includes a roller body 121 and a roller shaft 122 disposed at the end of the roller body 121. An elastic member 123 is sleeved on the roller shaft 122, and one end of the elastic member 123 abuts against the roller body 121. An adjusting member 124 is disposed on one side of the elastic member 123 to deform the elastic member 123. Exemplarily, the elastic member 123 may be a spring, which is sleeved on the roller shaft 122, and one end of which abuts against the roller body 121. The adjusting member 124 may be a push block, a pressing block, etc., which is mainly used to press the elastic member 123 to cause elastic deformation, apply resistance to the roller body 121, and make the pressing roller 12 less likely to rotate. By controlling the adjusting member 124, the size of the resistance applied to the roller body 121 can be controlled, and the degree of easy rotation of the pressing roller 12 can be adjusted, so that the pressing roller 12 can adapt to a variety of different conveying rollers 20 and prevent the pole piece 60 from flying.

[0033] During use, the pole piece 60 is running on the conveying roller 20. At this time, the pressing roller 12 is not in contact with the conveying roller 20. The compression degree of the elastic member 123 is adjusted in advance so that the resistance provided to the roller body 121 adapts to the rotation speed of the conveying roller 20. When the pole piece 60 breaks, the moving assembly 11 drives the pressing roller 12 to move and press on the conveying roller 20, and contacts the pole piece 60 to prevent the pole piece 60 from flying.

[0034] The moving assembly 11 is provided to drive the pressing roller 12 to press the conveying roller 20, thereby preventing the pole piece on the conveying roller 20 from flying; wherein, elastic members 123 are provided on both sides of the pressing roller 12, and the elastic members 123 apply resistance to the roller body 121 of the pressing roller 12, so that it is not easy to rotate. Compared with the existing motor drive, the pressing roller 12 will move synchronously with the conveying roller 20 after pressing the conveying roller 20, preventing the pole piece 60 from wrinkling due to asynchronous movement, and reducing the waste of the pole piece 60. And by adjusting the compression amount of the elastic member 123, the ease of rotation of the pressing roller 12 can be adjusted, so that it can be applied to a variety of different conveying rollers 20.

[0035] Example 2

[0036] The difference between Example 2 and Example 1 is that the present embodiment further optimizes the pole piece anti-flying belt device 10. Figure 1-4Furthermore, the adjusting member 124 is a nut, which is sleeved on the roller shaft 122, and the nut abuts against one end of the elastic member 123 facing away from the roller body 121. The nut is rotatably arranged on the roller shaft 122, and by rotating the nut clockwise or counterclockwise, the deformation amount of the elastic member 123 can be adjusted, and the resistance applied by the elastic member 123 to the roller body 121 can be controlled, so that the pressing roller 12 can be suitable for the conveying roller 20 of different speeds. This setting is simple to operate, has a stable adjustment effect, and can well reduce the manufacturing cost of the pole piece anti-flying belt device 10.

[0037] In some embodiments, a buffer is further provided between the elastic member 123 and the roller body 121. The buffer may be an end cap, a rubber product, a buffer, etc., which is mainly used to buffer the roller body 121. The end of the elastic member 123 abuts against the buffer, and the other side of the buffer abuts against the roller body 121, thereby increasing the service life of the roller body 121 and preventing the elastic member 123 from rubbing against the surface of the roller body 121 and causing damage to the roller body 121.

[0038] In some embodiments, the moving assembly 11 includes a driving member 111 and a limiting member 112. The driving member 111 is transmission-connected to the pressing roller 12, and the limiting member 112 is disposed on one side of the pressing roller 12 to limit the pressing roller 12. The driving member 111 may be an air cylinder, an oil cylinder, etc., and the limiting member 112 is a limiting block. Exemplarily, the limiting member 112 is disposed at the end of the pressing roller 12. When the driving member 111 drives the pressing roller 12 to descend, one end of the pressing roller 12 or one end of the driving member 111 abuts against the limiting member 112, so that it cannot move downward, which can effectively prevent the contact force between the pressing roller 12 and the conveying roller 20 from being too large, thereby damaging the pole piece 60, or even damaging the roller body 121.

[0039] In some embodiments, the moving assembly 11 further includes a first connecting block 113 and a second connecting block 114, a rotating shaft 115 is provided on one side of the first connecting block 113, one end of the second connecting block 113 is connected to the rotating shaft 115, and the other end is connected to the driving end of the driving member 111. The connecting block is provided to connect with the pressing roller 12, wherein the first connecting block and the second connecting block are block-shaped, and the first connecting block 113 can be fixedly provided on the outside. For example, if the driving member 111 is a cylinder, the pressing roller 12 is provided on the second connecting block 114, and when the cylinder is extended, the second connecting block can be driven to swing through the rotating shaft 115, thereby driving the pressing roller 12 to swing.

[0040] In some embodiments, the pressing roller 12 is a rubber roller, which is less likely to damage the pole piece 60.

[0041] Example 3

[0042] This embodiment provides a pole piece anti-flying belt device, referring to Figure 5, including a frame 1 and a pole piece anti-flying belt device 10, a conveying roller 20 is provided on the frame 1, and the pole piece anti-flying belt device 10 is arranged on one side of the conveying roller 20. There can be multiple conveying rollers 20, and multiple conveying rollers 20 are arranged on the frame 1 along the tape-feeding direction of the pole piece 60. There can be multiple pole piece anti-flying belt devices 10, and the specific number is determined according to the actual situation, which are arranged above the conveying roller 20. This device can prevent the pole piece 60 from flying around when the pole piece 60 breaks, and at the same time, during the working process of the anti-flying belt, it can prevent the pole piece 60 from wrinkling due to asynchronous movement, thereby improving the efficiency and stability of the transmission of the pole piece 60, significantly reducing the waste of the pole piece 60, saving costs for the enterprise, and improving production efficiency.

[0043] In some embodiments, adjustment limit blocks 30 are respectively provided on both sides of the first connection block to limit the installation position of the first connection block. The first connection block is arranged on the frame 1, and the limit blocks are arranged on the upper and lower sides of the first connection block. When the installation position of the first connection block needs to be adjusted, its installation position can be limited to prevent the driving member 111 from being unable to drive the pressing roller 12 to abut against the conveying roller 20 due to the large difference in the installation position. The setting method of the first limit member 112 can be to set a connection groove on the frame 1, and fix the first limit member 112 by means of bolts passing through the connection groove. This method is conducive to adjusting the position of the first installation member, or directly installing it on the frame 1 through a clamping block or a bolt. This embodiment does not limit this.

[0044] In some embodiments, a gap is left between the pressing roller 12 and the conveying roller 20, and a protective member 40 is provided on one side of the gap to prevent the hand from being pinched. The protective member 40 may be in a block shape, specifically, an angle iron, and is mainly used to protect the staff. During operation, since the conveying roller 20 moves too fast, and a gap is left between the conveying roller 20 and the pressing roller 12 in a normal state, the staff is prevented from accidentally placing their hands in the gap, thereby causing injury to the hands, or the moving components 11 such as the cylinder move the pressing roller 12 and press the staff. The protective member 40 may also be provided on both sides of the gap to protect both sides and improve the safety of the equipment.

[0045] In some embodiments, the frame 1 is further provided with a tape splicing platform 50 for splicing the pole piece 60. The tape splicing platform 50 is arranged on the upper side of the frame 1 to splice the pole piece 60 after the tape is broken. The tape splicing platform 50 can press the ends of the broken tape and another pole piece 60 by pressing to complete the tape splicing. By providing the tape splicing platform 50, the pole piece 60 after the tape is broken can be spliced ​​immediately, thereby improving production efficiency.

[0046] In some embodiments, the frame 1 is also provided with a sensor for sensing whether the pole piece 60 is broken. The sensor can be provided on one side of the conveying roller 20 to sense the conveying condition of the pole piece 60. When the pole piece 60 is broken, the sensor can transmit a signal to the anti-flying belt device, and the anti-flying belt device is pressed down. By providing the sensor, the automation degree of the equipment can be improved.
