Description

Technical Field

[0001] This utility model relates to the field of battery plate cutting technology, and in particular to a plate roller-type cutting device. Background Technology

[0002] Battery plates are the core components of a battery, responsible for storing and releasing electrical energy through electrochemical reactions during charging and discharging. They mainly consist of positive plates, negative plates, current collectors, and separators. During discharge, the active material at the positive electrode oxidizes and releases lithium ions, while the negative electrode receives and reduces the ions. During charging, the reverse reaction restores the stored energy state.

[0003] To adapt to battery design, the plates need to be cut to specific sizes. The mainstream cutting method is disc shearing, which uses the rolling shearing action of upper and lower disc cutters to cut the plates. It is low-cost and efficient, but it is easy to generate metal burrs during the cutting process. In addition, since the plates are not pressed down and fixed by other mechanisms during the cutting process, the downward pressure of the cutter alone cannot ensure the stability of the plate position during the cutting. This causes the edges of the plates to curl up when cutting the middle connector of multiple rows of plates, resulting in large dimensional errors of the plates after cutting and easily producing scrap.

[0004] To address this issue, we propose a plate roller-type cutting device. Utility Model Content

[0005] The main purpose of this utility model is to provide a plate roller-type cutting device. By pressing down the edge of the plate with the pressing component, the plate and its edge will not curl up when the first and second cutters are cutting, thereby ensuring that the plate is cut neatly and reducing the possibility of defective products.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A plate roller cutting device includes a roller cutter disc and a rotary drive device for driving the roller cutter disc to rotate. Several cross-cutting blades are fixed on both sides of the circumference of the roller cutter disc, and several blade holders are fixed at the center of the circumference of the roller cutter disc. A first cutting blade is fixed at one end of the top of the blade holder, and a second cutting blade is fixed at the other end of the top of the first cutting blade. Pressing components for pressing down the plate frame are respectively provided on both sides of the blade holder.

[0008] Furthermore, the pressing assembly includes a threaded hole on the cutter head, a screw is threadedly connected to the threaded hole, a spring is provided at the bottom of the threaded hole, a plug is fixed at the top of the spring, and a plug hole is provided at the bottom of the screw, with the plug and the plug hole being rotatably connected.

[0009] Furthermore, an elastic pressure head is fixed to the top of the screw.

[0010] Furthermore, the first cutter and the second cutter are located on both sides of the cutter holder.

[0011] Furthermore, the rotary drive device includes a motor and a reducer, the power output shaft of the motor is connected to the power input end of the reducer, and the power output end of the reducer is connected to the shaft on one side of the hobbing disc.

[0012] Furthermore, a bearing housing is connected to the shaft on the other side of the hobbing disc.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The pressing component of this invention presses down on the edge of the electrode plate, so that the electrode plate and its edge will not curl up when the first and second cutters are cutting, thereby ensuring that the electrode plate is cut neatly and reducing the possibility of defective products.

[0015] The spring of this invention is always in a retracted state. Therefore, the compressed spring will exert a force on the screw, thereby causing the screw thread teeth to face the thread groove of the bottom threaded hole, thus improving the stability of the screw and preventing the length of the screw extending out of the threaded hole from changing during the operation of this device.

[0016] The rubber ball of this invention has good deformation capability. Therefore, during the rotation of the roller cutter disc, the elastic pressure head can fully press down on the edge of the electrode plate through its own deformation, ensuring the stability of the electrode plate during cutting.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-3 As shown, a roller-type cutting device for electrode plates includes a roller cutter disc 2 and a rotary drive device 1 for driving the roller cutter disc 2 to rotate. Several cross-cutting blades 3 are fixed on both sides of the circumference of the roller cutter disc 2, and several blade holders 4 are fixed at the center of the circumference of the roller cutter disc 2. A first cutter 401 is fixed at one end of the top of the blade holder 4, and a second cutter 402 is fixed at the other end of the top of the first cutter 401. Pressing components 5 for pressing down the electrode plate frame are respectively provided on both sides of the blade holder 4. When the first cutter 401 and the second cutter 402 cut the edge of the electrode plate, the pressing components 5 will press down the edge of the electrode plate, so that the electrode plate and its edge will not curl up when the first cutter 401 and the second cutter 402 are cutting, thereby ensuring that the electrode plate is cut neatly.

[0024] In this embodiment, such as Figure 2 and Figure 3 As shown, the pressing component 5 includes a threaded hole 501 opened on the roller disc 2, a screw 505 is threadedly connected to the threaded hole 501, a spring 502 is provided at the bottom of the threaded hole 501, an insert rod 503 is fixed at the top of the spring 502, and an insertion hole 504 is opened at the bottom of the screw 505. The insert rod 503 and the insertion hole 504 are rotatably connected.

[0025] like Figure 2 and Figure 3 As shown, the length of the screw 505 extending out of the threaded hole 501 can be adjusted, so that when the device is cutting electrode plates of different thicknesses, the end of the screw 505 can effectively press down on the edge of the electrode plate. Furthermore, since the spring 502 is always in a retracted state, the compressed spring 502 will apply a force to the screw 505, thereby causing the thread teeth of the screw 505 to face the thread groove of the bottom threaded hole 501, thus improving the stability of the screw 505 and preventing the length of the screw 505 extending out of the threaded hole 501 from changing during the operation of the device.

[0026] The insertion rod 503 is inserted into the insertion hole 504. When the screw 505 rotates, the insertion rod 503 will rotate inside the insertion hole 504. The insertion hole 504 is located at the bottom center of the screw 505, and the insertion rod 503 is located at the top center of the spring 502. Therefore, even if the screw 505 rotates multiple times, the spring 502 will not be tilted.

[0027] like Figure 3As shown, an elastic pressure head 506 is fixed to the top of the screw 505. The elastic pressure head 506 is made of rubber and is spherical. It has good deformation ability. Therefore, during the rotation of the roller cutter 2, the elastic pressure head 506 can fully press down on the edge of the electrode plate through its own deformation to ensure the stability of the electrode plate during cutting.

[0028] The first cutter 401 and the second cutter 402 are located on both sides of the cutter holder 4, and the electrode plate before cutting is as follows: Figure 4 As shown, the two columns of electrode plates are connected by a connector between the frame. The first cutter 401 and the second cutter 402 cut off both ends of the connector, thereby cutting the connector off the electrode plate frame to separate the two columns of electrode plates.

[0029] The rotary drive device 1 includes a motor 101 and a reducer 102. The power output shaft of the motor 101 is connected to the power input end of the reducer 102. The power output end of the reducer 102 is connected to the shaft on one side of the roller cutter disc 2. The motor 101 drives the roller cutter disc 2 to rotate through the reducer 102, thereby causing the cross-cutting blade 3, the first cutter 401 and the second cutter 402 on the roller cutter disc 2 to generate cutting force to cut the electrode plate.

[0030] Among them, such as Figure 1 As shown, the shaft on the other side of the roller cutter 2 is connected to a bearing seat. The bearing seat and the rotary drive device 1 are connected to the frame on the conveyor line, thereby fixing the device on the conveyor line. At this time, the electrode plate is conveyed by the conveyor line and passes under the roller cutter 2. When the roller cutter 2 rotates, the electrode plate can be cut.

[0031] Working principle: First, the bearing housing and rotary drive device 1 are connected to the frame on the conveyor line, thereby fixing the device on the conveyor line. At this time, the electrode plate is conveyed by the conveyor line and passes under the roller cutter 2. At the same time, the motor 101 drives the roller cutter 2 to rotate through the reducer 102, thereby causing the cross-cutting blade 3, the first cutter 401 and the second cutter 402 on the roller cutter 2 to generate cutting force. When the electrode plate is conveyed to the bottom of the roller cutter 2, the cross-cutting blade 3, the first cutter 401 and the second cutter 402 will cut the electrode plate. The cross-cutting blade 3 cuts the electrode plates in the same row apart. The first cutter 401 and the second cutter 402 cut the two ends of the connecting piece respectively, thereby cutting the connecting piece off the edge of the electrode plate to separate the two rows of electrode plates. During the cutting process, the elastic pressure head 506 will substantially press down on the edge of the electrode plate under the action of the screw 505 to ensure the stability of the electrode plate during cutting.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
