Description

Technical Field

[0001] This utility model relates to the technical field of extrusion equipment for cable production, and in particular to an extrusion equipment for power cable production. Background Technology

[0002] Extruders are important plastic machinery. Most plastic products can be produced and manufactured through extrusion molding. Extruded products include filaments, tapes, tubes, strips, and sheets. In the production of power cables, extrusion equipment plays a crucial role, as it is responsible for processing plastic granules into cable sheaths.

[0003] In the process of using extrusion equipment in cable production, the feeding structure design of traditional cable production extrusion equipment is relatively simple. During the process of heating and melting, the plastic particles are not stirred and crushed. The plastic particles accumulate together, which can easily cause the plastic particles to not melt completely, thus affecting the quality of cable production.

[0004] Therefore, to address the aforementioned problem of difficulty in improving the dissolution efficiency of plastic granules, an extrusion device for power cable production can be designed. During the use of the cable production extrusion device, the device can crush and pulverize the plastic granules, which can not only prevent the plastic granules from clogging during the discharge process, but also improve the dissolution efficiency of the plastic granules, thereby making the plastic granules melt more completely and having the characteristics of high efficiency and stability. Utility Model Content

[0005] In order to overcome the problem that plastic granules are prone to clogging during the discharge process of cable extrusion equipment, which not only affects production efficiency and reduces the quality of cable sheath, but also that incomplete dissolution of plastic granules can affect the uniformity and strength of cable sheath, thus adversely affecting the overall performance of the cable, it is necessary to improve the plastic granule dissolution efficiency.

[0006] The technical solution of this utility model is as follows: an extrusion device for power cable production, comprising an extrusion cylinder, a heating layer, a protective shell, a storage tank, a discharge pipe, an extrusion auger, a drive motor, a drive shaft, an arc-shaped filter plate, a driven shaft, a crushing wheel, a drive gear, a driven gear, and a transmission gear chain. The extrusion cylinder has a heating layer inside. A protective shell is fixedly installed on the rear side wall of the extrusion cylinder. A storage tank is installed at the top of the rear end of the extrusion cylinder, and a discharge pipe is installed below the storage tank. An extrusion auger is rotatably installed inside the extrusion cylinder. A drive motor is fixedly installed on the side wall of the protective shell, and a drive shaft is installed at the output end of the drive motor. An arc-shaped filter plate is fixedly installed inside the discharge pipe. A driven shaft is rotatably installed inside the discharge pipe. A crushing wheel is fixedly installed on one side wall of the driven shaft. A drive gear is fixedly installed on the side wall of the drive shaft, and a driven gear is fixedly installed on the other side wall of the driven shaft. A transmission gear chain is installed inside the protective shell.

[0007] Preferably, during the operation of the cable production extrusion device, plastic granules first enter the discharge pipe, which is equipped with an arc-shaped filter plate for preliminary screening and interception of the plastic granules. Simultaneously, the drive motor is started, and its output end drives the drive gear to rotate via the drive shaft. Since the drive gear and driven gear mesh with the inner walls of the upper and lower ends of the transmission gear chain, the drive gear drives the driven gear to rotate via the transmission gear chain. The driven gear, in turn, drives the crushing wheel to rotate via the driven shaft. This crushes the larger particles intercepted by the arc-shaped filter plate, ensuring that the particles are fine and uniform. The crushed plastic granules then fall through the arc-shaped filter plate into the extrusion chamber. Inside the extrusion cylinder, the plastic granules are then dissolved through a heating layer. Simultaneously, the drive shaft rotates the extrusion auger, which transports the solvent from the rear to the front of the cylinder. Finally, the plastic solvent is extruded through the extrusion head at the front of the cylinder. This entire process achieves mixing, crushing, heating, and extrusion of the plastic granules, ensuring the quality and performance of the cable sheath. In summary, this device can crush and grind plastic granules, preventing blockages during discharge and improving the dissolution efficiency, resulting in more complete melting and exhibiting high efficiency and stability.

[0008] Preferably, the lower end of the discharge pipe is fixedly connected to the top of the rear end of the extrusion cylinder, one end of the drive shaft is fixedly connected to one end of the extrusion auger, the other end of the driven shaft is rotatably connected to the inner wall of the protective shell, the drive gear meshes with the lower inner wall of the transmission gear chain, and the driven gear meshes with the upper inner wall of the transmission gear chain.

[0009] Preferably, a stirring motor is fixedly installed on the top of the storage tank, a stirring shaft is installed at the output end of the stirring motor, and a stirring frame is installed on the side wall of the stirring shaft.

[0010] Preferably, an extrusion head is fixedly installed on the front side wall of the extrusion cylinder, a feed pipe is installed above the storage tank, and a tank cover is installed above the feed pipe.

[0011] Preferably, a handle is fixedly provided on the top of the can lid, and a connecting edge is fixedly provided on the top side wall of the feed pipe, with a connecting hole opened inside the connecting edge.

[0012] Preferably, a connecting shaft is provided inside the connecting hole, the connecting shaft is rotatably connected to the connecting hole, and one side of the can lid is fixedly connected to the two side walls of the connecting shaft.

[0013] Preferably, a hinge spring is provided on the outside of the connecting shaft, one end of which is fixedly connected to the side wall of one end of the connecting shaft, and the other end of which is fixedly connected to the inner wall of the connecting hole.

[0014] The beneficial effects of this utility model are:

[0015] During the operation of the extrusion unit in cable production, plastic granules first enter the discharge pipe, where an arc-shaped filter plate is installed to initially screen and intercept the granules. Simultaneously, the drive motor is activated, and its output shaft drives the drive gear to rotate. Since the drive gear and driven gear mesh with the inner walls of the upper and lower ends of the transmission gear chain, the drive gear drives the driven gear to rotate, which in turn drives the crushing wheel to rotate via the driven shaft. This crushing process crushes the larger granules intercepted by the arc-shaped filter plate, ensuring the granules are fine and uniform. The crushed plastic granules then fall through the arc-shaped filter plate into the extrusion cylinder. Inside, the plastic granules inside the extrusion cylinder are then dissolved through a heating layer. Simultaneously, the drive shaft rotates the extrusion auger synchronously, transporting the solvent from the rear to the front of the extrusion cylinder. Finally, the plastic solvent is extruded through the extrusion head at the front of the cylinder. This entire process achieves mixing, crushing, heating, and extrusion of the plastic granules, ensuring the quality and performance of the cable sheath. In summary, this device can crush and grind plastic granules, preventing blockages during discharge and improving the dissolution efficiency, resulting in more complete melting and exhibiting high efficiency and stability.

The extrusion tube 5 and extrusion cylinder 1 are equipped with an extrusion auger 6 that rotates inside. The protective shell 3 is fixedly mounted on the side wall of the extrusion tube 5. The output end of the extrusion tube 7 is equipped with a drive shaft 8. The discharge tube 5 is fixedly mounted with an arc-shaped filter plate 9. The discharge tube 5 is also equipped with a driven shaft 10 that rotates inside. One end of the driven shaft 10 is fixedly mounted with a crushing wheel 11. The drive shaft 8 is fixedly mounted with a drive gear 12 on the side wall of the drive shaft 8. The other end of the driven shaft 10 is fixedly mounted with a driven gear 13. The protective shell 3 is equipped with a transmission gear chain 14.

[0024] Please see Figure 1 and Figure 4The lower end of the discharge pipe 5 is fixedly connected to the top of the rear end of the extrusion cylinder 1. One end of the drive shaft 8 is fixedly connected to one end of the extrusion auger 6. The other end of the driven shaft 10 is rotatably connected to the inner wall of the protective shell 3. The drive gear 12 meshes with the lower inner wall of the transmission gear chain 14, and the driven gear 13 meshes with the upper inner wall of the transmission gear chain 14. The drive gear 12 can drive the driven gear 13 to rotate through the transmission gear chain 14. The driven gear 13 can drive the crushing wheel 11 to rotate through the driven shaft 10. A stirring motor 15 is fixedly installed on the top of the storage tank 4. The output end of the stirring motor 15 is set with... There is a stirring shaft 16, and a stirring frame 17 is provided on the side wall of the stirring shaft 16. When the stirring motor 15 is started, its output end can drive the stirring frame 17 to rotate through the stirring shaft 16. The stirring frame 17 can mix and stir the plastic granules inside the storage tank 4 to ensure that the granules are uniform. An extrusion head 18 is fixedly provided on the front side wall of the extrusion cylinder 1. A feed pipe 19 is provided above the storage tank 4, and a tank cover 20 is provided above the feed pipe 19. First, the plastic granules are added into the storage tank 4 through the feed pipe 19. Finally, the plastic solvent is extruded through the extrusion head 18 at the front end of the extrusion cylinder 1.

[0025] Please see Figure 4 and Figure 5 A handle 21 is fixedly installed on the top of the can lid 20, and a connecting edge 22 is fixedly installed on the top side wall of the feed pipe 19. A connecting hole 23 is opened inside the connecting edge 22. Pulling the handle 21 upwards will allow the can lid 20 to rotate and open. A connecting shaft 24 is installed inside the connecting hole 23 and is rotatably connected to the connecting hole 23. One side of the can lid 20 is fixedly connected to the two side walls of the connecting shaft 24. The can lid 20 can be rotated and opened through the connecting shaft 24. A hinge spring 25 is installed outside the connecting shaft 24. One end of the hinge spring 25 is fixedly connected to one side wall of the connecting shaft 24, and the other end of the hinge spring 25 is fixedly connected to the inner wall of the connecting hole 23. Under the action of the hinge spring 25, the can lid 20 can be driven to rotate and close.

[0026] When the cable production extrusion device is in use, firstly, pull the handle 21 upwards, which will allow the can cover 20 to be rotated and opened via the connecting shaft 24. Then, plastic granules are added into the storage tank 4 through the feed pipe 19.

[0027] At this time, the stirring motor 15 is started, and its output end can drive the stirring frame 17 to rotate through the stirring shaft 16. The stirring frame 17 can mix and stir the plastic particles inside the storage tank 4 to ensure that the particles are uniform. Then, the plastic particles enter the discharge pipe 5. The discharge pipe 5 is equipped with an arc-shaped filter plate 9 to perform preliminary screening and interception of the plastic particles.

[0028] At the same time, the active motor 7 is started, and its output end can drive the active gear 12 to rotate through the active shaft 8. Since the active gear 12 and the driven gear 13 mesh with the inner walls of the upper and lower ends of the transmission gear chain 14 respectively, the active gear 12 can drive the driven gear 13 to rotate through the transmission gear chain 14. The driven gear 13 can drive the crushing wheel 11 to rotate through the driven shaft 10. This can crush the larger particles intercepted by the arc-shaped filter plate 9, ensuring that the particles are small and uniform. The crushed plastic particles then fall into the interior of the extrusion cylinder 1 through the arc-shaped filter plate 9. Subsequently, the plastic particles inside the extrusion cylinder 1 are dissolved through the heating layer 2.

[0029] At this time, the drive shaft 8 can drive the extrusion auger 6 to rotate synchronously. The solvent can be transported from the rear end of the extrusion cylinder 1 to the front end of the extrusion cylinder 1 through the extrusion auger 6. Finally, the plastic solvent is extruded through the extrusion head 18 at the front end of the extrusion cylinder 1.

[0030] The entire process achieves the mixing, crushing, heating, and extrusion of plastic granules, ensuring the quality and performance of the cable sheath. In summary, this device can crush and grind plastic granules, which not only prevents blockage during the discharge process but also improves the dissolution efficiency of plastic granules, resulting in more complete melting and exhibiting high efficiency and stability.

[0031] Through the above steps, during the operation of the cable production extrusion device, firstly, plastic granules enter the discharge pipe 5. The discharge pipe 5 is equipped with an arc-shaped filter plate 9, which performs preliminary screening and interception of the plastic granules. Simultaneously, the drive motor 7 is started, and its output end can drive the drive gear 12 to rotate via the drive shaft 8. Since the drive gear 12 and driven gear 13 mesh with the inner walls of the upper and lower ends of the transmission gear chain 14 respectively, the drive gear 12 can drive the driven gear 13 to rotate via the transmission gear chain 14. The driven gear 13 can then drive the crushing wheel 11 to rotate via the driven shaft 10. This crushing process crushes the larger particles intercepted by the arc-shaped filter plate 9, ensuring that the particles are fine and uniform. The crushed plastic granules are then further crushed by the arc-shaped filter plate 9. The filter plate 9 falls into the extrusion cylinder 1. Then, the plastic particles inside the extrusion cylinder 1 are dissolved by the heating layer 2. At this time, the drive shaft 8 can drive the extrusion auger 6 to rotate synchronously. The extrusion auger 6 can transport the solvent from the rear end of the extrusion cylinder 1 to the front end of the extrusion cylinder 1. Finally, the plastic solvent is extruded through the extrusion head 18 at the front end of the extrusion cylinder 1. The whole process realizes the mixing, crushing, heating and extrusion of plastic particles, ensuring the quality and performance of the cable sheath. In summary, this device can crush and grind plastic particles, which can not only prevent the plastic particles from clogging during the discharge process, but also improve the dissolution efficiency of plastic particles, so that the plastic particles melt more completely, and has the characteristics of high efficiency and stability.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
