The outer wall is rotatably connected to a pushing device 54, and the inner wall of the pushing device 54 is rotatably connected to an extrusion device 55. The output end of the DC motor 2 is fixedly connected to the inner wall of the connecting flange 52, and the outer wall of the fixing device 53 is fixedly connected to the inner wall of the fixing cylinder 41. When the DC motor 2 on the splicing plate 1 is started, the output end of the DC motor 2 will drive the connecting flange 52 to rotate, thereby driving the extrusion device 5 to start. Since the connecting flange 52 is fixedly connected to the driving rod 51, the driving rod 51 starts to rotate. When the driving rod 51 rotates, it will drive some components on the driving rod 51 to rotate synchronously. When the driving rod 51 rotates, the rotating disk 541 of the pushing device 54 will be driven to rotate synchronously, and the rotating disk 541 is fixed to the driving rod 51 through the connecting hole 542, and the spiral blades 543 on the outer wall of the rotating disk 541 will also rotate accordingly. Since the tip of the spiral blades 543 is conical and matches the conical guide groove 44 in the fixed cylinder 41, the copper is pushed toward the extrusion port position, which can more accurately guide the flow direction of the copper material. Through the left and right guide structure formed by the pushing device 54 and the protective shell 4, the copper material can be pushed toward the extrusion port position in an orderly manner.

[0028] The fixing device 53 includes a fixing ring 531, the outer wall of which is fixedly connected to a fixing gear 532, the inner walls of the fixing gear 532 and the fixing ring 531 are both provided with connecting holes 533, the outer wall of the fixing ring 531 is fixedly connected to the inner wall of the fixing cylinder 41, and the inner wall of the fixing gear 532 is rotatably connected to the outer wall of the driving rod 51 through the connecting hole 533.

During the rotation of the driving rod 51, the rotating rod 552 driven by the spiral blade 543 and the rotating disk 541 will start to rotate under the engagement of the fixed gear 532 because it is fixed on the rolling gear 551, and the rotating rod 552 drives the engaging block 553 to rotate together, and the protruding setting of the engaging block 553 realizes the extrusion and pushing of the copper material.

[0030] The extrusion device 55 includes a rolling gear 551, the inner wall of which is fixedly connected to a rotating rod 552, the inner wall of which is fixedly connected to a fitting block 553, the rolling gear 551 meshes with the fixed gear 532, and the outer wall of the rotating rod 552 is rotatably connected to the inner wall of the spiral blade 543 via a through hole 544.

[0031] Example 2: Please refer to Figure 1-Figure 9 The present invention provides a technical solution: on the basis of embodiment 1, the auxiliary device 6 includes a first fixed sleeve 61, the outer wall of the top of the first fixed sleeve 61 is fixedly connected to the servo motor 62, the output end of the servo motor 62 is fixedly connected to the transmission rod 63, the outer wall of the transmission rod 63 is fixedly connected to the driving gear 64, the outer wall of the transmission rod 63 is fixedly connected to the arc-shaped stirring plate 67, the end of the transmission rod 63 away from the servo motor 62 is rotatably connected to the second fixed sleeve 68, a rotating sleeve 66 is arranged below the transmission rod 63, the outer wall of the rotating sleeve 66 is fixedly connected to the driven gear 65, the first fixed sleeve 61 and the second fixed sleeve 68 are stably fixed on the base 3, providing stable positioning and fixing for the fixed cylinder 41.

[0032] The outer wall at the bottom of the first fixed sleeve 61 and the outer wall at the bottom of the second fixed sleeve 68 are fixedly connected to the outer wall at the top of the base 3, the inner side wall of the first fixed sleeve 61 and the inner side wall of the second fixed sleeve 68 are fixedly connected to the outer wall of the fixed cylinder 41, the driving gear 64 is meshed with the driven gear 65, the outer wall of the driving gear 64 is rotatably connected to the inner wall of the fixed cylinder 41 through the limit groove 43, the outer side wall of the rotating sleeve 66 is rotatably connected to the inner wall of the fixed cylinder 41 through the rotating groove 42, the inner side wall of the rotating sleeve 66 is rotatably connected to the outer wall of the spiral blade 543, the outer wall of the transmission rod 63 is rotatably connected to the inner wall of the connecting pipe 45, and the servo motor 62 is started. The output end of the drive rod 63 drives the drive rod 63 to rotate. Due to the setting of the limit groove 43, the driving gear 64 on the drive rod 63 is stably meshed with the driven gear 65. At the same time, the rotating sleeve 66 rotates in the rotating groove 42 of the fixed cylinder 41. The rotating sleeve 66 and the spiral blade 543 rotate in opposite directions, which increases the friction on the copper material, thereby assisting the copper in being pushed and maintaining stable fluidity. At the same time, the drive rod 63 also drives the arc-shaped stirring plate 67 to rotate together, turning over the copper material at the internal position of the connecting tube 45, reducing the air gap between the copper materials, and also preventing the copper materials from being piled up or blocked during the feeding process.

[0033] Working principle:

[0034] When in use, the DC motor 2 on the splicing plate 1 is started, and the output end of the DC motor 2 will drive the connecting flange 52 to rotate, thereby driving the extrusion device 5 to start. Since the connecting flange 52 is fixedly connected to the driving rod 51, the driving rod 51 starts to rotate. When the driving rod 51 rotates, it will drive some components on the driving rod 51 to rotate synchronously. Since the fixing ring 531 in the fixing device 53 is fixed to the inner wall of the fixing cylinder 41, the fixing device 53 is immovable, and the fixing gear 532 is fixed to the fixing ring 531. Therefore, the fixing gear 532 will not rotate synchronously with the driving rod 51 at this time. At this time, the driving rod 51 transmits force to the pushing device 54 through the connecting hole 533;

[0035] When the driving rod 51 rotates, it will drive the rotating disk 541 of the pushing device 54 to rotate synchronously, and the rotating disk 541 is fixed to the driving rod 51 through the connecting hole 542, and the spiral blade 543 on the outer wall of the rotating disk 541 also rotates accordingly. Since the tip of the spiral blade 543 is tapered and matched with the tapered guide groove 44 in the fixed cylinder 41, the copper is pushed to the extrusion port position in a concentrated manner, which can more accurately guide the flow direction of the copper material. The guiding structure formed by the joint action of the pushing device 54 and the protective shell 4 can push the copper material to the extrusion port position in an orderly manner, avoiding the situation that the copper material is scattered and the flow is disordered during the transportation process, thereby improving the transportation efficiency of the copper material in the extruder, so that the copper material can be quickly and smoothly gathered to the extrusion port, reducing the retention and accumulation of the copper material during transportation, and effectively avoiding the blockage caused by accumulation. At the same time, this special matching design enables the copper material to be extruded more concentratedly at the extrusion port position, ensuring that the extruded copper material is more uniform in shape and size, and improving the quality and stability of the extruded product;

[0036] The through hole 544 on the spiral blade 543 cooperates with the rotating rod 552. The rotating rod 552 driven by the spiral blade 543 and the rotating disk 541 will start to rotate under the meshing of the fixed gear 532 because it is fixed on the rolling gear 551. The rotating rod 552 drives the engaging block 553 to rotate together. The convex setting of the engaging block 553 realizes the extrusion and pushing of the copper material, and at the same time increases the fluidity of the copper material, making the transportation process of the copper material smoother.

[0037] During the extrusion of the copper material, the first fixed sleeve 61 and the second fixed sleeve 68 are stably fixed on the base 3, providing a stable positioning and fixing effect for the fixed cylinder 41. At this time, some components in the auxiliary device 6 start to work, and the servo motor 62 is started. Its output end will drive the transmission rod 63 to rotate. Due to the setting of the limit groove 43, the driving gear 64 on the transmission rod 63 is stably meshed with the driven gear 65. At the same time, the rotating sleeve 66 rotates in the rotating groove 42 of the fixed cylinder 41. The rotating rotating sleeve 66 and the spiral blade 543 rotate in opposite directions, which increases the friction on the copper material, thereby assisting the copper to be pushed and maintaining stable fluidity. At the same time, the transmission rod 63 also drives the arc-shaped stirring plate 67 to rotate together, flipping the copper material in the internal position of the connecting tube 45, reducing the air gap between the copper materials, and also preventing the copper materials from being piled up or blocked during the feeding process;

[0038] A protective shell 4 is provided to assist the raw material input and extrusion operations during the copper processing. In the input part, a hopper 47 and an inner sleeve 46 are provided to work together. A layer of air-filled cavity is provided between the inner sleeve 46 and the connecting pipe 45. The different thermal conductivity of air and metal makes it difficult for the copper material feeding position to cool down quickly, thereby allowing the copper material to maintain a stable flow state and enter the extruder. The discharge position is adapted to the extrusion die by providing a sealing ring 48 and a threaded groove 49. When the extrusion die is screwed into the extrusion port position through the threaded groove 49, the sealing ring 48 is used to further improve the sealing of the equipment to prevent the extruded copper material from falling.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
