Description

Technical Field

[0001] This utility model relates to the field of lithium belt extrusion technology, specifically to a lithium belt extrusion machine with an adjustable extrusion nozzle. Background Technology

[0002] The extrusion device for lithium strip processing is the main equipment for realizing lithium strip extrusion processing. Lithium strip extrusion processing is an important method of forming metal by plastic pressure. With the rapid development of lithium replenishment technology, the demand for ultra-thin metal lithium strips has increased dramatically. At present, the industry mainly produces lithium strips of different specifications and models by extruding lithium ingots.

[0003] Chinese Patent Publication No. CN218963647U discloses a lithium strip extrusion device, which includes an extrusion cylinder, a vacuum chamber, and an extrusion section. The extrusion cylinder has an extrusion chamber with a lithium outlet at one end. The vacuum chamber is located on the upper part of the extrusion cylinder and has an openable and closable communication port between the vacuum chamber and the extrusion chamber. The vacuum chamber is used to hold lithium ingots and has a heating section capable of heating the lithium ingots. The heated lithium ingots can enter the extrusion chamber through the communication port. The extrusion section is located at the other end of the extrusion chamber and has an extrusion end extending into the extrusion chamber, which can extrude the lithium ingots toward the lithium outlet. The lithium strip extrusion device of this invention uses a vacuum chamber to heat and melt the lithium ingots, which then enter the extrusion cylinder, and the extrusion section extrudes the lithium strips toward the lithium outlet. This lithium strip extrusion device can reduce the extrusion pressure, improve production efficiency, reduce production costs, and achieve the production of ultra-thin lithium strips.

[0004] When the above-mentioned device needs to produce lithium strips of different widths, it can change extrusion nozzles of different thicknesses by working with bolts and fixing holes. However, when it is necessary to produce lithium strips of various thicknesses, it is necessary to change the extrusion nozzles frequently, which not only increases the production interruption time, but also reduces the additional costs that may be incurred due to changing tools, such as the need to prepare multiple extrusion nozzles of different thicknesses. Utility Model Content

[0005] To address the aforementioned issues, a lithium strip extruder with an adjustable extrusion nozzle is provided. By rotating a bidirectional screw, two threaded blocks are brought closer together, and simultaneously, a connecting block on the side wall of the threaded blocks moves. The other end of the connecting block presses an adjusting plate, causing the adjusting plate to move and thus adjusting the width of the discharge port inside the extrusion nozzle. This allows lithium strips of different widths to be extruded, avoiding the need for operators to change the extrusion nozzle multiple times.

[0006] To address the problems of existing technologies, this utility model provides a lithium strip extruder with an adjustable extrusion nozzle, comprising an extrusion base, a support base on the top of the extrusion base, an annular heating plate on the top of the support base, an extrusion tank inside the annular heating plate, a pusher plate for extruding material movably disposed inside the extrusion tank, an extrusion rod on one side of the pusher plate, one end of the extrusion rod extending to the outside of the extrusion tank and disposed of with an extrusion device, an extrusion nozzle connected to the discharge end of the extrusion tank, and an adjustment component for adjusting the extrusion width of the material inside the extrusion nozzle.

[0007] Preferably, the adjusting assembly includes a bidirectional screw rotatably disposed inside the extrusion nozzle, both ends of the bidirectional screw being threaded with threaded blocks, the sidewalls of the threaded blocks being rotatably disposed with connecting blocks, and the other end of the connecting blocks being rotatably disposed with an adjusting plate for adjusting the material extrusion width.

[0008] Preferably, the adjusting plate is internally equipped with a circular discharge plate for extruding cylindrical materials.

[0009] Preferably, a rotating rod is rotatably provided at the front end of the circular discharge plate, a rotating block is provided at one end of the rotating rod, a positioning rod is movably provided at one end of the rotating block, a limiting plate is provided outside the positioning rod, a compression spring is sleeved on the outside of the rotating rod, one end of the compression spring is connected to the rotating block, and the other end of the compression spring is connected to the limiting plate. The adjusting plate and the extrusion nozzle are both provided with positioning holes that are adapted to the positioning rod.

[0010] Preferably, the top of the extrusion tank is provided with a feed hopper for feeding materials.

[0011] Preferably, the extrusion device is a hydraulic rod.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. By rotating the bidirectional screw, the two threaded blocks are driven to move closer to each other. At the same time, the connecting block on the side wall of the threaded block will also move. The other end of the connecting block is used to squeeze the adjustment plate, so that the adjustment plate moves and adjusts the width of the discharge port inside the extrusion nozzle. At this time, lithium strips of different widths can be extruded, avoiding the need for workers to change the extrusion nozzle multiple times.

[0014] 2. By pulling the positioning rod upward, the positioning rod is moved away from the positioning hole inside the adjusting plate. Then, the rotating block is pulled to move the circular discharge plate. After that, the positioning rod is inserted into the positioning hole inside the extrusion nozzle. At this time, the extruded lithium strip will form a cylindrical shape under the action of the circular discharge plate. Thus, a circular lithium strip can be extruded without changing the extrusion equipment, which improves the practicality of the device. Attached Figure Description

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 7 As shown, this utility model provides:

[0025] An adjustable extrusion nozzle lithium strip extruder includes an extrusion base 1, a support base 7 on the top of the extrusion base 1, an annular heating plate 5 on the top of the support base 7, an extrusion tank 2 inside the annular heating plate 5, a pusher plate 8 for extruding material movably arranged inside the extrusion tank 2, an extrusion rod 6 on one side of the pusher plate 8, one end of the extrusion rod 6 extending to the outside of the extrusion tank 2 and equipped with an extrusion device, an extrusion nozzle 3 connected to the discharge end of the extrusion tank 2, and an adjustment component for adjusting the extrusion width of the material inside the extrusion nozzle 3.

[0026] The material inside the extrusion tank 2 can be heated by the annular heating plate 5, which can better produce lithium strips. Externally, the extrusion rod 6 is moved by external equipment, and the pusher plate 8 at one end of the extrusion rod 6 also moves, thereby pushing the lithium ingot to move. Finally, it is extruded from the discharge port inside the extrusion nozzle 3, thus producing lithium strips. Then, the width of the discharge port inside the extrusion nozzle 3 can be adjusted by the adjustment component, thereby extruding lithium strips of different widths.

[0027] like Figure 4 As shown, the adjustment assembly includes a bidirectional screw 9 rotatably disposed inside the extrusion nozzle 3. Both ends of the bidirectional screw 9 are threaded with threaded blocks 11. A connecting block 12 is rotatably disposed on the side wall of the threaded block 11. An adjustment plate 10 for adjusting the material extrusion width is rotatably disposed on the other end of the connecting block 12.

[0028] The two-way screw 9 drives the two threaded blocks 11 to move closer to each other. At the same time, the connecting block 12 on the side wall of the threaded block 11 also moves. The other end of the connecting block 12 presses the adjusting plate 10, causing the adjusting plate 10 to move and adjust the width of the discharge port inside the extrusion nozzle 3. At this time, lithium strips of different widths can be extruded, avoiding the need for workers to replace the extrusion nozzle 3 multiple times.

[0029] like Figure 6 and Figure 7 As shown, the regulating plate 10 is internally equipped with a circular discharge plate 13 for extruding cylindrical materials.

[0030] By using the circular discharge plate 13, which is set inside the regulating plate 10, the lithium strip is formed into a cylindrical shape under the action of the circular discharge plate 13 during extrusion, so that a circular lithium strip can be extruded without changing the extrusion equipment.

[0031] like Figure 7 As shown, a rotating rod 14 is rotatably mounted on the front end of the circular discharge plate 13. A rotating block 15 is mounted on one end of the rotating rod 14. A positioning rod 16 is movably mounted on one end of the rotating block 15. A limiting plate 18 is mounted on the outside of the positioning rod 16. A compression spring 17 is sleeved on the outside of the rotating rod 14. One end of the compression spring 17 is connected to the rotating block 15, and the other end of the compression spring 17 is connected to the limiting plate 18. Positioning holes that are compatible with the positioning rod 16 are opened inside the adjusting plate 10 and the extrusion nozzle 3.

[0032] By pulling the positioning rod 16 upward, the positioning rod 16 is moved away from the positioning hole inside the adjusting plate 10. Then, the rotating block 15 is pulled to move the circular discharge plate 13. After that, the positioning rod 16 is inserted into the positioning hole inside the extrusion nozzle 3 to prevent the circular discharge plate 13 from sliding randomly during the extrusion operation.

[0033] like Figure 1 As shown, the top of the extrusion tank 2 is provided with a feed hopper 4 for feeding.

[0034] The feed hopper 4 facilitates the feeding of materials into the extrusion tank 2.

[0035] like Figure 1 As shown, the extrusion equipment includes hydraulic rods, etc.

[0036] The extrusion process is carried out by hydraulic rods, which further improves the extrusion efficiency. At the same time, hydraulic rods can be replaced by electric push rods and other equipment that can realize automated extrusion.

[0037] Working principle: When lithium strip needs to be produced, lithium ingots are first fed into the extrusion tank 2 through the feed hopper 4. Then, external equipment drives the extrusion rod 6 to move, and the pusher plate 8 at one end of the extrusion rod 6 also moves accordingly, thus pushing the lithium ingot to move. Finally, it is extruded from the discharge port inside the extrusion nozzle 3, thus producing lithium strip. When lithium strips of different widths need to be produced, the bidirectional screw 9 is rotated to drive the two threaded blocks 11 to move closer to each other. At the same time, the connecting block 12 on the side wall of the threaded block 11 also moves. The other end of the connecting block 12 presses the adjusting plate 10, causing the adjusting plate 10 to move and thus adjust the extrusion nozzle. The width of the internal discharge port 3 allows for the extrusion of lithium strips of different widths, avoiding the need for operators to repeatedly replace the extrusion nozzle 3. When a round lithium strip needs to be extruded, first pull the positioning rod 16 upwards to move it away from the positioning hole inside the adjusting plate 10. Then pull the rotating block 15 to move the round discharge plate 13. After that, insert the positioning rod 16 into the positioning hole inside the extrusion nozzle 3. The extruded lithium strip will then form a cylindrical shape under the action of the round discharge plate 13. This allows for the extrusion of round lithium strips without changing the extrusion equipment, improving the practicality of the device.
