[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. The utility model is provided with a lifting plate. When the waste metal after extrusion is located at the top of the lifting plate, the hydraulic cylinder 1 is started. The output shaft of the hydraulic cylinder 1 drives the rack to slide, the rack drives the gear to rotate, the gear drives the rotating rod to rotate.

Under the repeated extrusion of the pushing block and the pushing plate, the waste metal can be fully extruded into a block, enabling the lifting plate to transport the waste metal block upward. Compared with the traditional device, the design of the sliding baffle allows the waste metal to be initially and stably extruded on the extrusion table, ensuring that the waste metal does not move around when subjected to force, thus achieving a more uniform and sufficient primary compression. Subsequently, when the sliding baffle slides backward, the intervention of the pushing block and the pushing plate performs a secondary precise extrusion on the waste metal, further enhancing the density and block quality of the waste metal and maintaining the stability and safety of the operation of the lifting plate.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 5 shown, the present invention provides a briquetting device for waste metal recycling, including a bottom table 1 of the machine. A lifting groove 14 is opened at the top right of the bottom table 1 of the machine. A fixed block 12 is fixedly installed at the top of the lifting groove 14. A fixed rod 11 is rotatably installed in the middle of the fixed block 12 and the fixed rod 11 penetrates through the fixed block 12.

First hinge blocks 4 are fixedly sleeved at both ends of the first hinge rod 5. A rising plate 3 is fixedly installed at the top of the first hinge block 4.

[0021] The staff places the scrap metal in the extrusion table 2 and starts the device. The output shaft of the third hydraulic cylinder 29 pushes the extrusion plate 25 to turn and extrude the scrap metal. The scrap metal is extruded downward on the left side of the sliding baffle 15. The output shaft of the third hydraulic cylinder 29 retracts, driving the extrusion plate 25 to turn upward. Then the motor 23 is started. The output shaft of the motor 23 drives the second pulley 20 to rotate. The second pulley 20 drives the first pulley 18 to rotate through the belt 19. The first pulley 18 drives the threaded rod 16 to rotate. The threaded rod 16 drives the sliding baffle 15 to slide backward. The second hydraulic cylinder 27 is started. The output shaft of the second hydraulic cylinder 27 drives the pushing block 26 to move to the right. The pushing block 26 moves to the right and moves relative to the pushing plate 32 to extrude the scrap metal, so that the scrap metal is extruded on the top of the rising plate 3. The output shaft of the second hydraulic cylinder 27 retracts, driving the pushing block 26 to move to the left. The first hydraulic cylinder 22 is started. The output shaft of the first hydraulic cylinder 22 pushes the rack 13 to slide at the bottom of the lifting groove 14. The sliding of the rack 13 drives the gear 10 to rotate. The gear 10 drives the rotating rod 9 to rotate. The rotating rod 9 and the rotating column 6 are hinged through the second hinge block 8 and the second hinge rod 7 to drive the rotating column 6 to rotate. The rotating column 6 and the first hinge block 4 are hinged through the first hinge rod 5 to push the rising plate 3 to move upward. The rising plate 3 drives the extruded scrap metal block to move upward.

[0022] By providing the rising plate 3, when the extruded scrap metal is located on the top of the rising plate 3, the first hydraulic cylinder 22 is started. The output shaft of the first hydraulic cylinder 22 drives the rack 13 to slide. The rack 13 drives the gear 10 to rotate. The gear 10 drives the rotating rod 9 to rotate. Through the hinged cooperation between the rotating rod 9 and the rotating column 6, the rotating column 6 pushes the rising plate 3 to rise, driving the extruded scrap metal block to rise, completing automatic discharging, which is convenient for handling. Compared with the traditional device, it does not require manual handling, significantly reducing the labor intensity and improving the automation level of the production line. This not only reduces the labor cost but also avoids the safety risks that may be brought by manual operation, thus improving the overall production efficiency. The scrap metal block is removed through a stable rising action, reducing physical collision and wear, protecting the integrity of the scrap metal block, being beneficial to subsequent processing and utilization, and improving the resource recovery rate.

[0023] Among them, the top of the machine base table 1 is fixedly installed with the extrusion table 2. The right side of the extrusion table 2 is rotatably installed with the threaded rod 16 and the threaded rod 16 penetrates through the extrusion table 2. A sliding baffle 15 is threadedly sleeved on the outer surface of the threaded rod 16. A chute 21 is opened on the back of the extrusion table 2. The sliding baffle 15 is slidably installed on the right side of the extrusion table 2 through the chute 21.

The first pulley 18 is fixedly connected with the threaded rod 16. A belt 19 is fixedly sleeved on the outer surface of the first pulley 18. The bottom inner surface of the belt 19 is fixedly sleeved with the second pulley 20.

[0024] The staff places the scrap metal on the extrusion table 2, starts the third hydraulic cylinder 29, and the telescopic output shaft of the third hydraulic cylinder 29 drives the extrusion plate 25 to flip, so that the extrusion plate 25 squeezes the scrap metal downward on the left side of the sliding baffle 15. After one extrusion is completed, the extrusion plate 25 flips upward. Then, the motor 23 is started, and the output shaft of the motor 23 drives the second pulley 20 to rotate. The second pulley 20 drives the first pulley 18 to rotate through the belt 19. The first pulley 18 drives the threaded rod 16 to rotate, and the threaded rod 16 drives the sliding baffle 15 to slide on the outer surface of the threaded rod 16. Then, the second hydraulic cylinder 27 is started, and the output shaft of the second hydraulic cylinder 27 pushes the pushing block 26 to move rightward on the surface of the extrusion table 2, so that the pushing block 26 moves rightward to relatively squeeze the scrap metal block with the pushing plate 32 for the second time.

[0025] By providing the sliding baffle 15, the scrap metal can be subjected to a primary extrusion on the top of the extrusion table 2. The stability of the extrusion table 2 enables the scrap metal block to be fully extruded for the first time. After the first extrusion is completed, by starting the motor 23, the motor 23 drives a series of accessories to cooperate with each other to make the sliding baffle 15 slide backward on the surface of the extrusion table 2. Under the repeated extrusion of the pushing block 26 and the pushing plate 32, the scrap metal can be fully extruded into blocks, enabling the lifting plate 3 to transport the scrap metal blocks upward. Compared with traditional devices, the design of the sliding baffle 15 allows the scrap metal to be initially and stably extruded on the extrusion table 2, ensuring that the scrap metal does not move around when subjected to force, thereby achieving a more uniform and full initial compression. Subsequently, when the sliding baffle slides backward, the intervention of the pushing block 26 and the pushing plate 32 performs a secondary and precise extrusion on the scrap metal, further improving the density and block quality of the scrap metal and maintaining the stability and safety of the operation of the lifting plate 3.

[0026] Among them, a rack 13 is slidably installed at the bottom of the gear 10. The rack 13 is slidably installed at the bottom of the lifting groove 14. A first hydraulic cylinder 22 is fixedly installed on the back of the rack 13, and the output shaft of the first hydraulic cylinder 22 penetrates through the bottom machine table 1.

[0027] By providing the rack 13, the telescopic output shaft of the first hydraulic cylinder 22 drives the rack 13 to slide at the bottom of the lifting groove 14. The sliding of the rack 13 drives the gear 10 to rotate. The gear 10 drives a series of accessories to cooperate with each other to make the lifting plate 3 rise stably. By precisely controlling the telescopic amount of the output shaft of the first hydraulic cylinder 22, the sliding distance of the rack 13 can be precisely controlled. This precise control enables the rising height of the lifting plate 3 to be adjusted according to actual needs, meeting the processing requirements of scrap metal blocks of different specifications.

[0028] Among them, the extrusion plate 25 is hingedly installed on the left side of the extrusion table 2. The pushing block 26 is slidably installed at the bottom of the extrusion plate 25. A second hydraulic cylinder 27 is fixedly installed on the left side of the pushing block 26. A large fixing block 31 is fixedly installed at the right end of the limit fixing block 17.

[0029] By placing the scrap metal block on the surface of the extrusion table 2, the hydraulic cylinder three 29 pushes the extrusion plate 25 to flip, completing one extrusion. The hydraulic cylinder two 27 pushes the pushing block 26 to move to the right, completing the second extrusion. The hydraulic cylinder three 29 can quickly and powerfully push the extrusion plate 25 to flip, performing an initial rapid extrusion on the scrap metal block for preliminary shaping. Subsequently, the hydraulic cylinder two 27 pushes the pushing block 26 for the second extrusion to further refine and enhance the density of the scrap metal block. This continuous and efficient extrusion process greatly shortens the processing time of a single scrap metal block and improves the overall production efficiency.

[0030] Among them, a pushing table 30 is fixedly installed at the left top of the machine bottom table 1, a pushing plate 32 is fixedly installed on the right side of the machine bottom table 1.

The output shaft of the hydraulic cylinder three 29 is hingedly installed on the left side of the extrusion plate 25. The pushing table 30 is fixedly installed outside the hydraulic cylinder two 27.

[0031] By providing the pushing table 30, the hydraulic cylinder two 27 can operate inside the pushing table 30. Two support blocks 28 are fixedly installed on the top of the pushing table 30, which can enable the hydraulic cylinder three 29 to output stably. This design ensures that the hydraulic cylinder will not be displaced or deformed due to vibration or external impact during operation, thus ensuring the accuracy and stability of the pushing action. At the same time, the two support blocks 28 on the top of the pushing table 30 provide a firm support point for the hydraulic cylinder three 29, enabling it to maintain horizontal stability when flipping the extrusion plate 25 and preventing uneven extrusion or equipment damage caused by tilting or shaking.

[0032] Among them, a motor 23 is fixedly installed on the back of the machine bottom table 1. The output shaft of the motor 23 is fixedly installed in the middle of the belt pulley two 20. A motor protection box 24 is fixedly installed on the back of the machine bottom table 1. The motor protection box 24 is fixedly installed outside the motor 23 and the hydraulic cylinder one 22. The motor protection box 24 is fixedly installed at the bottom of the limit fixing block 17.

[0033] By fixedly providing the motor protection box 24, the motor protection box 24 provides a relatively enclosed and controlled environment for the motor 23 and the hydraulic cylinder one 22, effectively isolating harmful factors such as dust, moisture, and corrosive gases in the external environment. If these factors directly act on the motor and the hydraulic cylinder, it may cause electrical failures, accelerated mechanical wear, or hydraulic system contamination, thus affecting the normal operation and lifespan of the equipment. The existence of the motor protection box greatly reduces these risks and ensures the stable operation of the equipment in different environments.
