An extruder for facilitating uniform extrusion of a cable

Abstract

This utility model relates to the field of extrusion machine technology and discloses an extruder that facilitates uniform extrusion of cables. It includes an extruder body and a feed box connected to the top of the extruder body. It also includes a hollow rod rotatably connected to the front and rear of the feed box cavity, with several stirring rods connected to the surface of the hollow rod. When workers process cables through the extruder body, the filter screen filters impurities from the material, causing them to fall into a waste box, thus preventing excessive impurities from affecting the extruder body's discharge speed. Simultaneously, the rotating structure, in conjunction with the air inlet pipe, the housing, and the connecting pipe, allows the heat generated by the extruder body during operation to enter the interior of the stirring rods. During stirring, the stirring rods not only break up clumps of plastic particles but also provide a preheating effect.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6 As shown, an extruder for uniform extrusion of cables includes an extruder body 1 and a feed box 2 connected to the top of the extruder body 1. Hollow rods 8 are rotatably connected to the front and rear sides of the inner cavity of the feed box 2. Several stirring rods 9 are connected to the surface of the hollow rods 8. A rotating structure 14 is provided on one side of the hollow rods 8. The rotating structure 14 includes a first gear 141 fixed to one end of the hollow rod 8. A motor 142 is fixedly connected to one side of the feed box 2 through a fixing plate. A second gear 143 is fixedly connected to the output end of the motor 142. The first gear 141 and the second gear 143 mesh. The second gear 143 is fixed to another hollow rod 8. Through the rotating structure 14, the operator can start the motor 142, which drives the first gear 141, the hollow rods 8 and the stirring rods 9 to rotate through the second gear 143, thereby causing the stirring rods 9 to stir and disperse the material inside the feed box 2.

[0016] A connecting pipe 4 is connected to the other side of the hollow rod 8. An air inlet pipe 10 is connected to the inside of the extruder body 1. A housing 3 is connected to the top of the air inlet pipe 10. The housing 3 is connected to the connecting pipe 4. A housing 5 is fixedly connected to the top of the feed box 2. A feed box 6 is provided on one side of the housing 5. A filter screen 7 is slidably connected to the inner cavity of the feed box 6. A first slide groove 13 is opened on one side of the feed box 6. A transmission structure 15 is provided inside the first slide groove 13. The transmission structure 15 includes a first slider 151 slidably connected inside the first slide groove 13. A fixing rod 153 is fixedly connected inside the first slide groove 13. The fixing rod 153 is slidably connected to the first slider 151. A spring 154 is sleeved on the surface of the fixing rod 153. The two ends of the spring 154 are fixed to the first slider 151 and the inside of the first slide groove 13, respectively. A telescopic rod is fixedly connected to the bottom of one end of the first slider 151. 152, the bottom of the telescopic rod 152 is fixed to the filter screen 7, the bottom of the other end of the first slider 151 is fixedly connected to the transmission plate 156, the other end of the hollow rod 8 is fixedly connected to the cam 155, the cam 155 works in conjunction with the transmission plate 156, through the setting of the transmission structure 15, the rotation of the hollow rod 8 drives the cam 155 to rotate, and then the cam 155 applies force to the transmission plate 156, so that the transmission plate 156 drives the filter screen 7 to move through the first slider 151 and the telescopic rod 152. When the cam 155 stops applying force to the transmission plate 156, the spring 154 then uses its own elastic force to drive the first slider 151, the telescopic rod 152 and the filter screen 7 to reset. Repeat the above operation, so as to speed up the material falling speed on the surface of the filter screen 7. The waste box 18 is slidably connected inside the feed box 6.

[0017] The feed box 6 has a second slide groove 16 on both sides. The second slide groove 16 is slidably connected to the inside of the second slide groove 16. The two ends of the filter screen 7 are in contact with the inner wall of the feed box 6. Through the setting of the second slide groove 16 and the second slide groove 17, the filter screen 7 can move inside the feed box 6 through the second slide groove 17 and limit the filter screen 7. It can also prevent particles from falling into the gap between the filter screen 7 and the feed box 6.

[0018] The interior of the housing 3 is slidably connected to a rack 11, and the surface of the rack 11 is provided with an activated carbon plate 12. By setting up the rack 11 and the activated carbon plate 12, the gas discharged through the air inlet pipe 10 can be filtered, thereby reducing the harm to the environment. After multiple uses, the activated carbon plate 12 can be replaced through the rack 11.

[0019] The hollow rod 8 has an exhaust port 19 on its surface, and a dustproof net is installed inside the exhaust port 19. The pore size of the dustproof net is smaller than the size of the plastic particles. By setting the exhaust port 19, the gas can be discharged through the exhaust port 19 after the hot air preheats the hollow rod 8 and the stirring rod 9. The dustproof net can prevent material from falling into the exhaust port 19.

[0020] It is worth noting that the technical features proposed in this technical solution, such as the extruder body 1 and the feed box 2, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0021] Working principle: When the operator starts the extruder body 1, the material is first poured into the feed hopper 6. Then, impurities inside the material are filtered through the filter screen 7, causing them to fall into the waste box 18. At this time, the operator can start the motor 142, which drives the first gear 141, hollow rod 8, and stirring rod 9 to rotate via the second gear 143. This stirs the material in the feed hopper 2, ensuring even feeding. The hollow rod 8 then drives the cam 155 to rotate, applying force to the transmission plate 156. This causes the transmission plate 156 to move the filter screen 7 via the first slider 151 and the telescopic rod 152. When the cam 155 releases its force on the transmission plate 156... When the force is applied, the spring 154 then uses its own elastic force to drive the first slider 151, the telescopic rod 152 and the filter screen 7 to reset. Repeating the above operation can accelerate the material falling speed on the surface of the filter screen 7. As the extruder body 1 works, the hot air generated at this time will enter the box 3 through the air inlet pipe 10 and be filtered by the activated carbon plate 12. Then, the hollow rod 8 and the stirring rod 9 are preheated through the connecting pipe 4, which can dry and preheat the material to prevent the material from sticking together and causing blockage of the feed box 2. After preheating, the gas can be discharged through the exhaust port 19. After long-term operation, the staff can clean the impurities inside the waste box 18 and replace the activated carbon plate 12.
