Description

Technical Field

[0001] The utility model relates to the technical field of cable extruders, in particular to an anti-blocking nozzle of a wire and cable extruder. Background Art

[0002] Cable extruder is a device used to produce cables. Its main function is to extrude plastic or other insulating materials and coat them on the surface of wires or cables to provide insulation and protection. The nozzle of the cable extruder is prone to blockage after long-term use. The channel of the nozzle is blocked by impurities, residues or other substances, resulting in poor extrusion effect or production interruption. The existing clearing work can only remove the nozzle and use external force to infuse to squeeze out the impurities, which is time-consuming and labor-intensive. Utility Model Content

[0005] Preferably, the blockage clearing structure includes a connecting rod, which is inserted through the sleeve and the inner wall of the nozzle barrel, the lower end of the connecting rod is fixedly equipped with a scraper, the outer wall of the connecting rod is fixedly equipped with a connecting plate, the lower end of the connecting plate is fixedly equipped with a sliding rod, the outer wall of the nozzle barrel is fixedly equipped with a support plate, the sliding rod is inserted through the inner wall of the support plate, the lower end of the sliding rod is fixedly equipped with a bottom plate, the outer wall of the sliding rod is sleeved with a spring, one end of the spring is connected to the bottom plate, and the other end of the spring is connected to the support plate.

[0007] Preferably, a soft sleeve is arranged between the support plate and the bottom plate, and the soft sleeve is sleeved on the outer wall of the spring.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: a cable extruder nozzle component is formed by the nozzle barrel and the nozzle, and the cable extruder is connected through the action of the connecting section, and different nozzles are adjusted to work according to the needs of the cable extruder. Due to the long-term use of the nozzle, raw materials and impurities in the pipeline itself will accumulate, causing the nozzle to be blocked, affecting the molding effect. At this time, the action of the clearing structure can effectively drive the movement of raw materials and impurities inside the nozzle to solve the blockage problem, and the blocked raw materials and impurities are pushed away to be extruded through the nozzle. The action of the ring ensures that the raw materials can effectively enter the nozzle, while limiting the clearing structure to maintain a fixed trajectory displacement.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-3 The utility model provides an anti-blocking nozzle for a wire and cable extruder, comprising a nozzle barrel 1, a nozzle 2 is inserted into the upper end of the inner wall of the nozzle barrel 1, a connecting section 3 is fixedly connected to the lower end of the nozzle barrel 1, the outer wall of the connecting section 3 is threaded, a sleeve ring 6 is fixedly assembled at the lower end of the nozzle 2, the sleeve ring 6 is fitted to the inner wall of the nozzle barrel 1, and clearing structures 4 are symmetrically assembled on both sides of the inner wall of the sleeve ring 6, and the clearing structure 4 passes through the nozzle barrel 1 and is connected to the outer wall of the nozzle barrel 1.

[0015] The nozzle barrel 1 and the nozzle 2 form a complete cable extruder nozzle component, and the cable extruder is connected through the action of the connecting section 3. Different nozzles are adjusted according to the needs of the cable extruder. Since the nozzle 2 is used for a long time, raw materials and impurities in the pipeline itself will accumulate, causing the nozzle 2 to be blocked, affecting the molding effect. At this time, the clearing structure 4 can effectively drive the raw materials and impurities inside the nozzle 2 to move, solve the blockage problem, and push away the blocked raw materials and impurities to extrude them through the nozzle 2. The ring 6 ensures that the raw materials can effectively enter the nozzle 2, while limiting the clearing structure 4 to maintain a fixed trajectory displacement.

[0016] The clearing structure 4 includes a connecting rod 41, which is inserted through the collar 6 and the inner wall of the nozzle tube 1, a scraper 47 is fixedly mounted on the lower end of the connecting rod 41, a connecting plate 42 is fixedly mounted on the outer wall of the connecting rod 41, a slide rod 44 is fixedly mounted on the lower end of the connecting plate 42, a support plate 43 is fixedly mounted on the outer wall of the nozzle tube 1, the slide rod 44 is inserted through the inner wall of the support plate 43, a bottom plate 45 is fixedly mounted on the lower end of the slide rod 44, a spring 46 is sleeved on the outer wall of the slide rod 44, one end of the spring 46 is connected to the bottom plate 45, and the other end of the spring 46 is connected to the support plate 43.

[0017] When the clearing structure 4 is needed, first pull the connecting plate 42 on one side to drive the connecting rod 41 to move, and at the same time drive the sliding rod 44 to move. At this time, the connecting rod 41 drives the scraper 47 to move, stirs the impurities and raw materials in the nozzle tube 1 to move, pushes them to the position of the nozzle 2, and stirs and pushes the blocked position away. At the same time, the sliding rod 44 drives the bottom plate 45 to squeeze the spring 46 to deform it. As the connecting plate 42 is released, the bottom plate 45 will be squeezed back to its original position again according to the elastic force of the spring 46. This is repeated, which can effectively stir the raw materials inside the nozzle tube 1 for effective displacement, thereby achieving a good clearing work. When the sliding rod 44 is displaced, it will be restricted by the support plate 43 to maintain a fixed trajectory displacement.
