Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a cable extrusion device. Background Art

[0002] Cables generally consist of a wire core and an outer insulating layer that wraps the wire core to provide insulation. During the continuous production of cables, the wire core (mostly metal) is usually manufactured, and then the outer protective layer is fused with the wire core using wrapping equipment to obtain a complete cable. When manufacturing the outer protective layer, an extrusion device such as an extruder is often used.

[0003] In the prior art, when extruding, raw material particles are generally directly put into the extrusion equipment for corresponding melting, extrusion and other works to finally obtain the finished product. However, when a large amount of raw material particles are put in at one time, the raw material particles are uneven, which can easily cause blockage at the feed point, affecting the efficiency of the cable extrusion work. Therefore, a cable extrusion device is proposed to solve the above problem. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a cable extrusion device to prevent blockage caused by excessive accumulation of large particles. It can continuously scrape the raw material particles piled at the outlet of the feed box to loosen the accumulation, further prevent the accumulation of particles at the feed port, and ensure the working efficiency of the cable extrusion.

[0005] The technical solution for achieving the purpose of the utility model is: a cable extrusion device, comprising a mounting plate, a screw extrusion device is arranged on the mounting plate, a feed box is arranged on the mounting plate, the bottom end of the feed box is connected to the feed port of the screw extrusion device, a screening bin is arranged in the feed box, an anti-blocking component is arranged on the feed box, and the anti-blocking component is connected to the screening bin.

[0006] In some embodiments, the screening bin is slidably connected to the front inner wall of the feed box, a hollow groove is penetrated through the rear inner wall of the feed box, and the anti-blocking component includes a connecting plate slidably connected to the inner wall of the hollow groove, and the front side of the connecting plate is fixedly connected to the back side of the screening bin.

[0007] In certain embodiments, the anti-blocking component includes a mounting shell fixedly connected to the back side of the feed box, a driving motor is fixedly connected to the back side of the mounting shell, and a driving wheel is fixedly connected to the output end of the driving motor.

[0008] In some embodiments, the anti-blocking assembly further comprises a driving rod rotatably connected to the front side of the driving wheel, and an end of the driving rod away from the driving wheel is rotatably connected to the back side of the connecting plate.

[0009] In certain embodiments, the anti-blocking assembly further comprises a scraping wheel rotatably connected to the back side of the feed box, the driving wheel is connected to the scraping wheel via a belt drive, and a scraping rod is rotatably connected to the surface of the scraping wheel.

[0010] In some embodiments, the anti-clogging assembly further comprises a combing plate fixedly connected to the bottom end of the scraper rod, wherein the combing plate is located in the bottom outlet of the feed box.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First, the utility model sets an anti-blocking component, starts the driving motor, and the driving motor drives the driving wheel to rotate, and the driving wheel drives the driving rod to move. Under the limit of the empty slot, the moving plate will reciprocate left and right with the driving rod, so that the screening bin moves left and right, and the raw material particles are screened, which can leave larger and uneven raw material particles in the screening bin, and prevent excessive large particles from accumulating and causing blockage;

[0013] Secondly: The utility model provides a scraping wheel. When the driving wheel rotates, the scraping wheel is driven to rotate through a belt. The rotation of the scraping wheel causes the scraping rod to reciprocate and perform a pendulum-like motion at the outlet of the feed box under the condition of being limited (limiting groove).

[0014] The invention solves the problem that when a large amount of raw material particles are fed into the existing extrusion equipment at one time, the feed point is easily blocked due to uneven raw material particles, thereby affecting the efficiency of cable extrusion.
