[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0025] Reference Figure 1-6 As shown, an extruder for brass rod processing comprises an extruder body 1, a mounting frame 2 arranged outside the discharge end of the extruder body 1, and a connecting cylinder 3 rotatably arranged inside the mounting frame 2, a turntable 4 is fixedly sleeved on one end of the connecting cylinder 3 facing the extruder body 1, an electric push rod 5 is installed on the inner wall of the turntable 4, a telescopic rod of the electric push rod 5 faces the center of the turntable 4 and is installed with a cutter 6, and the discharge port of the extruder body 1 corresponds to the center of the connecting cylinder 3;

[0026] When in use, the brass rod after extrusion enters the connecting cylinder 3 from the discharge port of the extruder body 1, and then the connecting cylinder 3 and the turntable 4 are rotated as a whole, and the electric push rod 5 and the cutter 6 rotate along the brass rod as the center of the circle at the same time, and then the electric push rod 5 is turned on, and the electric push rod 5 pushes the cutter 6 to make slow linear motion, gradually increasing the cutting amount of the cutter 6, thereby realizing the cutting of the brass rod. The circular gradually advancing cutting structure can effectively avoid the traditional shearing mechanism, the poor treatment of the brass rod incision, the excessive shearing pressure is easy to cause the brass deformation at the incision, the density and texture are very different from the middle part of the brass rod, affecting the subsequent use of the brass rod, and the actual cutting effect is poor. The problems such as the incision of the brass rod is smooth and not deformed, and the cutting effect is good.

[0027] Further, refer to Figure 1-3As shown, it is worth noting that the outer cover of the turntable 4 is provided with a first protective cover 7 and a second protective cover 12 which are hingedly connected to each other from top to bottom, and a large semi-annular groove adapted to the connecting tube 3 is provided on one side of the open end of the first protective cover 7 and the second protective cover 12, and a small semi-annular groove corresponding to the discharge port of the extruder body 1 is provided on the other side of the open end of the first protective cover 7 and the second protective cover 12, and a driven gear disc 11 is fastened and sleeved on the outer wall of the turntable 4, and a motor 8 is installed on one side of the first protective cover 7, and the output shaft of the motor 8 rotates and penetrates into the first protective cover 7 and is fixed with a transmission rod 9, and a transmission gear 10 meshing with the driven gear disc 11 is fastened and sleeved on the rod body of the transmission rod 9;

[0028] By setting the motor 8, the transmission rod 9 and the driven gear plate 11, the motor 8 is turned on, and the output shaft of the motor 8 drives the transmission rod 9 and the transmission gear 10, so that the transmission gear 10 is meshed with the driven gear plate 11, thereby providing a rotational force for the rotating disk 4 and the connecting cylinder 3 as a whole, so that the electric push rod 5 and the cutting machine 6 rotate around the brass rod as the center of the circle;

[0029] By setting the first protective cover 7 and the second protective cover 12, a relatively closed space can be effectively provided for the driven sprocket 11 and the transmission gear 10, reducing the influence of external dust and impurities on the driven sprocket 11 and the transmission gear 10. In addition, by pulling the second protective cover 12 and flipping the second protective cover 12 to one side and separating it from the first protective cover 7, the interior of the first protective cover 7 can be exposed to the outside, thereby facilitating manual daily inspection and maintenance of the transmission gear 10 and the driven sprocket 11.

[0030] Although the above-mentioned embodiment utilizes the first protective cover 7 and the second protective cover 12 to seal and protect the driven sprocket 11 and the transmission gear 10, in practice, the driven sprocket 11 and the transmission gear 10 mesh and move in a sealed space, which is likely to generate a large amount of heat. Once the temperature inside the first protective cover 7 and the second protective cover 12 is too high, it is very easy to endanger the service life of the driven sprocket 11 and the transmission gear 10.

[0031] Further, refer to Figure 2-3 As shown, it is worth noting that the ends of the first protective cover 7 and the second protective cover 12 away from each other are both provided with ventilation grooves, and the bottom of the inner side of the first protective cover 7 is provided with a reciprocating air induction mechanism;

[0032] The reciprocating air induction mechanism comprises a fan 14 slidably disposed below the driven gear plate 11, a power component disposed on one side of the fan 14, and a guide component disposed on the other side of the fan 14;

[0033] By setting the ventilation groove and the reciprocating triggering mechanism, when the driven gear plate 11 is continuously meshed with the transmission gear 10, the fan 14 is turned on. The fan 14 can continuously suck the outside air from the ventilation groove on the first protective cover 7, and discharge the air outward from the ventilation groove on the second protective cover 12, thereby allowing the air inside the first protective cover 7 and the second protective cover 12 to flow, which is beneficial to heat dissipation. At the same time, the power component in the reciprocating triggering mechanism is used to cause the fan 14 to slide back and forth on the inner bottom of the first protective cover 7, so that the first protective cover 7 and the second protective cover 12 can be cooled from multiple places to improve the heat dissipation effect.

[0034] Further, refer to Figure 3-5 As shown, it is worth noting that the power component includes a transmission screw 15 that is laterally rotatably arranged between the inner walls on both sides of the first protective cover 7, a threaded sleeve that is fixedly connected to the outer wall of the turntable 4 is threadedly connected on the rod body of the transmission screw 15, an intermittent transmission component is arranged between the transmission screw 15 and the transmission rod 9, and an elastic re-rotation component is arranged on the outer side of the first protective cover 7;

[0035] The intermittent transmission assembly includes a rotating rod 19 vertically arranged between the transmission rod 9 and the transmission screw 15, a rotating seat 18 vertically fixed to the inner wall of the first protective cover 7 is rotatably sleeved on the rod body of the rotating rod 19, first bevel gears 20 are fixed at both ends of the rotating rod 19, a second bevel gear 21 meshing with one of the first bevel gears 20 is fixedly sleeved on the rod body of the transmission screw 15, and an incomplete gear 22 meshing with another first bevel gear 20 is also tightly sleeved on the rod body of the transmission rod 9;

[0036] The elastic re-rotation assembly includes a fixing sleeve 23 vertically fixed on the side wall of the first protective cover 7 and a torsion rod 24 arranged in the fixing sleeve 23. The torsion rod 24 rotates and penetrates into the first protective cover 7 and is fixedly connected to one end of the transmission screw 15. The rod body of the torsion rod 24 is sleeved with a torsion spring 25. One end of the torsion spring 25 is fixedly connected to the inner wall of the fixing sleeve 23, and the other end of the torsion spring 25 is fixedly connected to the rod body of the torsion rod 24.

[0037] During the rotation of the transmission rod 9, the incomplete gear 22 can intermittently mesh with one of the first bevel gears 20, thereby intermittently rotating the rotating rod 19. During the rotation of the rotating rod 19, the other first bevel gear 20 can mesh with the second bevel gear 21, thereby transmitting the transmission screw 15, so that the threaded sleeve can slide the fan 14 to one side by the threaded structure during the rotation of the transmission screw 15, and the torsion rod 24 synchronously deforms the torsion spring 25 on the inner side of the fixed sleeve 23, and then when the incomplete gear 22 moves to no longer mesh with the first bevel gear 20, the torsion rod 24 can rotate with the transmission screw 15 under the elastic force of the torsion spring 25, and similarly make the fan 14 slide in the opposite direction, thereby achieving the effect of reciprocating movement of the fan 14.

[0038] Further, refer to Figure 3 As shown, the guide component includes a guide rod 16 transversely fixed between the inner walls of both sides of the first protective cover 7, and a sliding sleeve 17 fixedly connected to the outer wall of the fan 14 is slidably sleeved on the rod body of the guide rod 16;

[0039] During the sliding of the fan 14 , the sliding sleeve 17 can synchronously slide along the rod body of the guide rod 16 , and the cooperation of the two can limit the moving track of the turntable 4 and ensure the stability of the turntable 4 during movement.

[0040] Further, refer to Figure 3 As shown, it is worth noting that a filter plate 13 is installed in the ventilation groove;

[0041] The filter plate 13 can be provided to effectively prevent dust and impurities in the external air from entering the first protective cover 7 and the second protective cover 12 through the ventilation grooves and contaminating the transmission gear 10 and the driven gear plate 11 .

[0042] Further, refer to Figure 2 As shown, it is worth noting that the four corners of the bottom surface of the first protective cover 7 are vertically fixed with 026;

[0043] Through the setting of 026, the distance between the first protective cover 7 and the ground can be expanded to a certain extent, avoiding the first protective cover 7 directly contacting the ground and affecting the external air extraction effect of the turntable 4.
