Description

Technical Field

[0001] The utility model belongs to the field of battery pole piece recycling and relates to a chain-guided multi-blade saw. Background Art

[0002] With the continuous growth of new energy vehicle ownership and the rapid development of the 3C market, there is a demand for large-scale lithium battery applications. The pole piece is an important component of lithium batteries. During the manufacturing process, the pole piece will inevitably be scrapped due to process flow or equipment failure. If the scrapped battery pole piece adopts ordinary garbage disposal methods such as landfill, incineration, composting, etc., the cobalt, nickel, lithium, manganese and other metals in the pole piece will inevitably cause serious pollution to the atmosphere, water and soil, which is extremely harmful. In addition to environmental considerations, the recycling of pole piece materials has multiple economic values, including energy value re-exploitation and material regeneration value. After the battery pole piece is scrapped, it is an indispensable strategic mineral resource in today's new energy era because it contains rich valuable metal elements such as nickel, cobalt, and lithium. Therefore, the recycling of battery pole pieces is imminent.

[0003] The main steps of the current domestic scrap electrode recycling program are: collection and transportation, shredding and sorting, and material recycling. However, in the practice of battery electrode recycling, it is found that some heavy coiled electrode materials cannot be directly fed into the shredder. If they are directly fed into the shredder, the shredder will be stuck and the production line will be affected. Therefore, before this part of the coiled material is fed into the shredder, the industry currently uses manual chopping and band saw cutting, which is inefficient and unsafe. Utility Model Content

[0004] The utility model aims to provide a chain-guided multi-blade saw to solve the problems of low efficiency and unsafety in the prior art that the heavy coiled core pole pieces need to be manually chopped and cut with a cutting saw before being fed into a shredder.

[0006] When the above-mentioned chain-guided multi-blade saw is working, after the battery electrode is placed on the first conveyor, it is conveyed under the action of the first conveyor. When the battery electrode is conveyed to the position of the saw blade, the conveyor belt of the second conveyor above can contact and press the battery electrode. The battery electrode can continue to be conveyed in the pressed state and finally be cut by the saw blade. Since there are multiple saw blades, the saw blades can be set to an equally spaced arrangement structure, so that the battery electrode can be evenly cut, thereby replacing the low efficiency and unsafe problems caused by manual chopping, and replacing the low efficiency caused by using a single cutting saw.

[0007] As a preferred solution of the present utility model, the first conveyor is a chain-guided conveyor, and the saw blade is located between two adjacent chains.

[0008] As a preferred solution of the utility model, the second conveyor includes a conveyor frame, both ends of which are provided with rotatable conveying shafts, and a clamping wheel that can elastically extend and retract in the vertical direction is provided at the lower middle position of the conveyor frame, and a conveying belt is wound around the two conveying shafts and the clamping wheel.

[0009] As a preferred solution of the utility model, a fixing rod is threadedly connected at the lower middle part of the conveyor frame, a support frame is sleeved on the fixing rod, the pressure wheel is rotatably connected to the lower end position of the support frame, and a spring is sleeved on the fixing rod between the conveyor frame and the support frame, and the spring can exert a downward force on the support frame in a natural state.

[0010] As a preferred solution of the utility model, a main shaft is connected to the center of the plurality of saw blades, and the main shaft is installed on the first conveyor by means of a bearing connection.

[0011] As a preferred solution of the utility model, a first transmission wheel is installed on the main shaft, a transmission motor is installed under the first conveyor, a second transmission wheel is connected to the shaft end of the transmission motor, and the first transmission wheel and the second transmission wheel are connected through a conveyor belt.

[0013] The utility model has the following beneficial effects: the utility model has a simple design structure and is easy to use. The chain conveyor is adopted to place multiple saw blades in the middle of the conveyor, and the saw blades are used to evenly cut the battery pole pieces.

DETAILED DESCRIPTION

[0017] like Figure 1-2 As shown, a chain-guided multi-blade saw includes a first conveyor 1, wherein the middle part of the first conveyor 1 has a plurality of concentric and synchronously rotating saw blades 6, wherein the first conveyor 1 is used to convey the battery electrodes placed on the first conveyor 1, and when conveyed to the position of the saw blade 6, a plurality of saw blades 6 can be used to cut the battery electrodes at the same time, replacing the traditional cutting method of a single saw blade 6, and having the advantage of high cutting efficiency.

[0018] A second conveyor 2 is provided above the first conveyor 1, and the conveyor belt 17 of the second conveyor 2 can convey the battery electrodes on the first conveyor 1 in a compressed state, wherein the second conveyor 2 is mainly used to achieve a pressing effect on the battery electrodes, and when the battery electrodes are pressed, it does not affect the normal transportation of the battery electrodes, so that the battery electrodes remain stable during the cutting process to avoid material leakage problems.

[0019] A dustproof isolation cover 3 is arranged in the middle of the first conveyor 1. The dustproof isolation cover 3 can be welded by stainless steel plates, or a glass cover or a transparent plastic cover. Setting it to a transparent state can facilitate the staff to observe the working condition of the internal saw blade 6. The saw blade 6 and the second conveyor 2 are both located inside the dustproof isolation cover 3. The dustproof isolation cover 3 can prevent sawdust, debris, dust, etc. generated during cutting from spreading outward. On the other hand, it can also avoid unnecessary safety accidents caused by the saw blade 6 being exposed, thereby achieving the effect of safety protection.

[0020] Specifically, the first conveyor 1 is a guide chain conveyor, and the saw blade 6 is located between two adjacent chains. The guide chain conveyor is a chain conveyor, which adopts sprockets and chains to achieve transmission effects. More specifically, this guide chain conveyor includes a frame, rotatable shafts at both ends of the frame, a motor is installed on the shaft at one end, and multiple sprockets are installed on the shaft, and chains are installed on the sprockets. In this example, there are multiple chains, and sprockets are provided at both ends of the chain. The sprockets at each end are concentric and synchronously rotated. The multiple sprockets can be connected by the same main shaft. In this way, an independent gap will be formed between the two chains, which is convenient for the installation of the saw blade 6, so that the saw blade 6 can extend upward from the gap between the two chains, thereby cutting the conveyed battery electrode, wherein two adjacent saw blades 6 can be provided with one chain, or multiple chains can be provided, which can be specifically set according to the actual width of the battery electrode to be cut. The structure and principle of this guide chain conveyor belong to conventional technologies in the prior art and will not be elaborated here.

[0021] Specifically, the second conveyor 2 includes a conveyor frame 12, and rotatable conveying shafts 11 are provided at both ends of the conveyor frame 12. The coaxial bearings at both ends of the conveying shaft 11 are connected to the conveyor frame 12 to achieve a rotation effect. One of the conveying shafts 11 is connected to a motor to realize power drive. A clamping wheel 16 that can elastically extend and retract in the vertical direction is provided at the lower middle position of the conveyor frame 12. A conveying belt 17 is wound around the two conveying shafts 11 and the clamping wheel 16. The clamping wheel 16 can be used to protrude the conveying belt 17 downward to contact the battery electrode below. Since the conveying belt 17 itself can rotate, when the moving speed of the conveying belt 17 is set to be consistent with the moving speed of the battery electrode, the battery electrode can be firmly pressed, and the problem of material leakage will not occur during the cutting process of the saw blade 6.

[0022] More specifically, a fixing rod 14 is threadedly connected to the lower middle part of the conveyor frame 12, and a support frame 15 is sleeved on the fixing rod 14. Both sides of the support frame 15 are slidably matched with the guide rods installed under the conveyor frame 12, so that the support frame 15 only has the freedom of axial movement relative to the fixing rod 14, and the clamping wheel 16 is rotatably connected to the lower end of the support frame 15, and is specifically installed at the lower end of the support frame 15 through a bearing. A spring 13 is sleeved on the fixing rod 14 between the conveyor frame 12 and the support frame 15, and the spring 13 can exert a downward force on the support frame 15 in a natural state, such as Figure 2 As shown, the spring 13 moves the clamping wheel 16 downward in a natural state, which can keep the conveyor belt 17 in an unfolded state as a whole on the one hand, and on the other hand, can press the lower surface of the conveyor belt 17 against the surface of the battery electrode to keep the battery electrode stable during the cutting process.

[0023] In addition, in order to be suitable for the compression and transportation of battery electrodes of different thicknesses, a bearing seat that can move horizontally is also provided at one end of the conveyor frame 12. By moving the left and right positions of the bearing seat, the tension of the conveyor belt 17 can be adjusted, and then combined with the elastic force of the spring 13, the position of the lower end of the conveyor belt 17 can be changed. Among them, the structure and principle of tightening the conveyor belt 17 by moving the position of the bearing seat belong to the conventional technology in the prior art and will not be elaborated here.

[0024] Specifically, a main shaft 4 is connected to the center of several saw blades 6, and the main shaft 4 is installed on the first conveyor 1 through a bearing connection. Both ends of the main shaft 4 are installed on the frame of the first conveyor 1 through bearings, or the main shaft 4 can also be installed on an independent frame. It does not affect the normal operation of the first conveyor 1. It only needs to ensure that the main shaft 4 can rotate to drive the saw blades 6 to rotate.

[0025] Specifically, a first transmission wheel 5 is installed on the main shaft 4, a transmission motor 8 is installed under the first conveyor 1, and a second transmission wheel 9 is connected to the shaft end of the transmission motor 8. The first transmission wheel 5 and the second transmission wheel 9 are connected by a conveyor belt 7, which is mainly used to drive the main shaft 4 to rotate, and then the main shaft 4 drives all the saw blades 6 to rotate together to achieve the cutting effect of the battery pole piece. Among them, the first transmission wheel 5 and the second transmission wheel 9 can be V-type pulleys, and the conveyor belt 7 matched therewith is a V-type belt, or the two transmission wheels are synchronous pulleys, and the conveyor belt 7 matched therewith is a synchronous belt. Other power transmission methods can also be used, which are not limited here.

[0026] Specifically, a dust removal port 10 is provided at the bottom of the dustproof isolation cover 3, and the dust removal port can be connected to an external vacuum cleaner to collect the dust generated during the cutting process. More specifically, the lower plane of the dustproof isolation cover 3 can be set as a conical structure, and the dust removal port 10 is set at the lowest end of the conical structure, so that the dust and other debris generated during the cutting process can be discharged from the dust removal port 10 under the action of its own gravity.

[0027] The use process of this chain-guided multi-blade saw is as follows: first place the battery electrode core material to be processed on the first conveyor 1, open the dust removal port 10, and the material is conveyed to the position of the saw blade 6 under the action of the first conveyor 1. When the battery electrode moves to the position of the saw blade 6, the conveyor belt 17 of the second conveyor 2 above can press the battery electrode so that the battery electrode can be cut in a compressed state, and the battery electrode is cut into strips, and then the first conveyor 1 is used to convey the material to the subsequent shredder equipment.

[0028] Although the specific embodiments of the present invention are described in detail above, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the present invention, and modifications or deformations without creative labor are still within the scope of protection of the present invention.
