[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figures 1 to 3 As shown, it includes a frame 1 and a conveyor belt 11 rotatably arranged on the frame 1. The rotation mode of the conveyor belt 11 is the prior art and will not be described in detail here. The plate cutting device also includes a roller 2 rotatably arranged on the frame 1 and located above the conveyor belt 11. There is a first gap between the roller 2 and the conveyor belt 11 for materials to pass through, and the roller 2 can move up and down relative to the conveyor belt 11. Two screw rods 21 are relatively arranged on the frame 1, and two nuts 22 are threadedly connected on each of the screw rods 21. The top of each screw rod 21 passes through one end of a bearing rod 23 and one end of each bearing rod 23 is located between the two nuts 22. The two ends of the roller 2 are respectively fixedly connected to the bearings at the other ends of the two bearing rods 23. A spring 24 is sleeved on each of the screw rods 21 and the spring 24 is located between the bearing rod 23 and the nut 22 above. The single plate obtained after cutting enters the conveyor belt 11, and the conveyor belt 11 transports it. When the single plate moves to the bottom of the pressing roller 2 under the drive of the conveyor belt 11, the pressing roller 2 further presses the lead paste on the single plate, and finally the conveyor belt 11 drives the pressed single plate to be unloaded.

[0022] When it is necessary to adjust the height of the pressing roller 2 according to the thickness of the single-piece electrode plate, first adjust the positions of the two nuts 22 on the screw 21, and then adjust the position of the bearing rod 23 on the screw 21, and finally change the height of the pressing roller 2. The setting of the spring 24 also allows the bearing rod 23 to have a certain displacement space. When the single-piece electrode plate moves to the bottom of the pressing roller 2, the pressing roller 2 can adapt to the thickness of the single-piece electrode plate so as to better press the lead paste onto the single-piece electrode plate.

[0023] The electrode plate cutting device of this embodiment can further press the lead paste on the single electrode plate obtained after cutting; it can also realize the pressing operation on single electrode plates of different thicknesses, and has a wide range of applications.

[0024] As an implementation method, the plate slitting device also includes a slitting mechanism 3, which includes a slitting roller 31 and a supporting roller 32 that are relatively rotatably arranged on one side of the frame 1, and a second gap for material to pass through is provided between the slitting roller 31 and the supporting roller 32. A chain rope group is rotatably arranged on the frame 1, and the chain rope group is inclined. One end of the chain rope group corresponds to the second gap, and the other end is located above one end of the conveyor belt 11, and the other end of the conveyor belt 11 is located below the pressure roller 2.

[0025] First, the continuous plate enters the middle of the slitting roller 31 and the supporting roller 32 from the right side of the frame. The slitting roller 31 and the supporting roller 32 rotate relative to each other to slit the plate in the middle, thereby obtaining a single plate. Then the single plate enters the chain rope group. Since the chain rope group is set at an angle (the single plate moves on the chain rope group by its own gravity), the single plate can enter the conveyor belt 11 through the chain rope group. The single plate is finally driven by the conveyor belt 11 to move directly below the pressure roller 2.

[0026] As an implementable embodiment, the slitting roller 31 and the supporting roller 32 are provided with a plurality of transverse grooves in the circumferential direction, and each of the transverse grooves is provided with a transverse cutting blade; the slitting roller 31 and the supporting roller 32 are provided with a plurality of vertical grooves in the axial direction, and each of the vertical grooves is provided with a vertical cutting blade. The pole plate is cut into single-piece pole plates by the action of the transverse cutting blades and the vertical cutting blades on the slitting roller 31 and the supporting roller 32, and the pole plate cutting efficiency is improved. The pole plate slitting device of this embodiment can not only realize the rapid slitting of the pole plate, but also can further compress the lead paste on the manufactured single-piece pole after slitting.

[0027] As an implementable embodiment, two rotating rollers 12 are rotatably arranged on the frame 1, and both rotating rollers 12 are rotatably arranged on the frame 1 through bearing seats, and the height of the horizontal plane where the rotating roller 12 close to the supporting roller 32 is located is greater than the height of the horizontal plane where the other rotating roller 12 is located, and the chain rope group includes a plurality of chain ropes 13, and the plurality of chain ropes 13 are evenly sleeved on the two rotating rollers 12. The plurality of chain ropes 13 of this embodiment support the single plate obtained after slitting, and since the height of the horizontal plane where the rotating roller 12 close to the supporting roller 32 is located is greater than the height of the horizontal plane where the other rotating roller 12 is located, the plurality of chain ropes 13 are in an inclined state, and the single plate is moved on the plurality of chain ropes 13 by its own gravity, and finally enters the conveyor belt 11.

[0028] As an implementable embodiment, the electrode plate slitting device further includes a receiving mechanism 4 located at the other end of the conveyor belt 11, the receiving mechanism 4 includes a receiving roller 41 rotatably arranged on the frame 1 and a receiving plate 42 slidably arranged on the frame 1, the receiving roller 41 is rotatably arranged on the frame 1 through a bearing seat, the receiving roller 41 is located at the front end of the receiving plate 42, the height of the horizontal plane where the receiving roller 41 is located is greater than the height of the horizontal plane where the receiving plate 42 is located and is less than the height of the horizontal plane where the conveyor belt 11 is located, the frame 1 is provided with a first linear module 14 and the slider of the first linear module 14 is fixedly connected to the receiving plate 42. The conveyor belt 11 drives the compacted single electrode plate to be unloaded, the receiving roller 41 guides so that the compacted single electrode plate passes through it and enters the receiving plate 42, the first linear module 14 is started, and drives the compacted single electrode plate on the receiving plate 42 to move to wait for the next operation.

[0029] As an implementation method, a plurality of receiving racks 421 are arranged at equal intervals on the receiving plate 42, and the plurality of receiving racks 421 are all located below the receiving roller 41. Specifically, the receiving roller 41 guides the compressed single-piece plate to pass through the receiving racks 421, and the plurality of receiving racks 421 support the compressed single-piece plate. The contact area between the plurality of receiving racks 421 and the compressed single-piece plate is small, which effectively avoids excessive wear of the compressed single-piece plate, and secondly, it is convenient for other stations to carry out the single-piece plate picking operation.

[0030] As an implementation method, multiple layers of protective cloth are wound around the pressure roller 2. The protective cloth can be made of non-woven fabric or PVC material, but is not limited to the above materials. The purpose of providing the protective cloth is to prevent the single piece of lead paste on the single plate from sticking to the pressure roller 2. After long-term use, the old protective cloth can be torn off manually, so that the new protective cloth is exposed to continue the operation.

[0031] As an implementation method, the slitting roller 31 and the supporting roller 32 are both rotatably arranged on the frame 1 through a bearing seat. A motor is arranged on the frame 1, and the output shaft of the motor is fixedly connected to one end of the slitting roller 31. When the motor is started, the slitting roller 31 is driven to rotate, thereby driving the pole plate and the supporting roller 32 to rotate.

[0032] The operation process of the plate cutting device is that the continuous plate first enters the middle of the cutting roller 31 and the supporting roller 32 from the right side of the frame. The cutting roller 31 and the supporting roller 32 rotate relative to each other to cut the plate located in the middle, thereby obtaining a single plate. After that, the single plate enters the chain rope group. Since the height of the horizontal plane where the rotating roller 12 close to the supporting roller 32 is located is greater than the height of the horizontal plane where the other rotating roller 12 is located, the multiple chains 13 are in an inclined state. The single plate moves on the multiple chains 13 by its own gravity and finally enters the conveyor belt 11. When the single plate moves to the right below the pressing roller 2 driven by the conveyor belt 11, the pressing roller 2 further presses the lead paste on the single plate on it. Finally, the conveyor belt 21 drives the pressed plate to unload, and the receiving roller 41 guides the pressed single plate to enter the receiving plate 42 through it. The first linear module 14 is started to drive the pressed single plate on the receiving plate 42 to move to wait for the next operation.

[0033] The embodiments described above are only preferred embodiments of the present invention and are only used to explain the present invention, not to limit the scope of implementation of the present invention. For those skilled in the art, other implementation methods can certainly be easily made by replacement or modification based on the technical contents disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of the present invention should be included in the scope of the patent application of the present invention.
