Description

Technical Field

[0001] This utility model relates to the field of cable extrusion technology, and more specifically to cable multi-extruder collaborative production equipment. Background Technology

[0002] Cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and so on. They are all composed of single or multiple strands of conductors and insulation layers, used to connect circuits, electrical appliances, etc. Cable extruders are equipment used to thermally extrude conductor cores to wrap them with insulation layers or sheaths.

[0003] During cable extrusion, plastic materials such as polyethylene and polyvinyl chloride decompose at high temperatures, releasing small-molecule organic compounds and forming organic waste gases. These organic waste gases include harmful gases such as benzene, toluene, and xylene, which are volatile and toxic. Existing cable extruders are unable to treat the generated organic waste gases, resulting in large amounts of these gases being emitted into the ambient air, posing a direct threat to the atmospheric environment and human health. Utility Model Content

[0004] The purpose of this invention is to provide a multi-extruder collaborative production equipment for cables, in order to solve the problem mentioned in the background art that existing cable extruders are unable to treat the generated organic waste gas, resulting in a large amount of organic waste gas being emitted into the ambient air, posing a direct threat to the atmospheric environment and human health.

[0005] To achieve the above objectives, this utility model provides a multi-extruder collaborative production equipment for cables, including a base, an extrusion cylinder fixedly mounted on the top of the base, a feed hopper fixedly mounted on the top of the extrusion cylinder, an extrusion port provided on the side end of the extrusion cylinder, a cooling pipe fixedly mounted on one side of the extrusion cylinder, a feed pipe fixedly mounted on the bottom end of the feed hopper, a purification mechanism provided on one side of the extrusion port, the purification mechanism including a purification chamber, an exhaust fan provided on the side of the purification chamber away from the base, a connecting pipe fixedly mounted between the exhaust fan and the purification chamber, a sleeve fixedly mounted at the end of the cooling pipe, multiple exhaust pipes fixedly mounted on the outer wall of the sleeve, all of the multiple exhaust pipes communicating with the inside of the sleeve, the bottom ends of the multiple exhaust pipes fixedly communicating with the purification chamber, three filter layers provided inside the purification chamber, and an exhaust pipe fixedly mounted on the side of the exhaust fan away from the purification chamber.

[0006] By adopting the above scheme, the organic waste gas is transported to the purification box, where it is adsorbed and purified by three filter layers to remove harmful substances and odors, thereby reducing the emission of organic waste gas into the ambient air.

[0007] As a further improvement to this technical solution, a crushing mechanism for cutting cable material is provided inside the feeding hopper. The crushing mechanism includes a fixed plate, which is fixedly installed on the top of the inner side of the feeding hopper. A motor is fixedly installed on the fixed plate, and the output shaft of the motor passes through the fixed plate and is fixedly installed on a rotating shaft. Multiple cutters are fixedly installed on the rotating shaft.

[0008] By adopting the above solution, multiple cutters are used to cut and crush the cable material, thereby avoiding the cable material from becoming too large and causing blockage inside the feed pipe.

[0009] As a further improvement to this technical solution, the bottom end of the rotating shaft extends into the feed pipe, and a conveying spiral blade is fixedly installed near the bottom end of the rotating shaft.

[0010] By adopting the above solution, the conveying screw is driven to rotate by the rotating shaft, so that the conveying screw can guide the material in the feed pipe and avoid excessive material causing internal blockage.

[0011] As a further improvement to this technical solution, multiple scrapers are fixedly installed on the rotating shaft, and the bottom ends of the multiple scrapers are in contact with the bottom of the inner side of the feed hopper.

[0012] By adopting the above scheme, the shaft is supported by multiple scrapers, which improves the stability of the shaft. The shaft drives the multiple scrapers to rotate, scraping the material from the bottom of the inner side of the feed hopper.

[0013] As a further improvement to this technical solution, all three filter layers are activated carbon mesh layers, and the top of the purification box has three openings for installing the three filter layers.

[0014] By adopting the above solution, and by setting up a three-layer detachable filter, it is convenient to remove the three filter layers for maintenance and replacement.

[0015] As a further improvement to this technical solution, each of the three filter layers has a sealing plate fixedly installed at its upper end through the purification box. The sealing plate contacts the top of the purification box and is used to seal the opening. By adopting the above solution, the connection between the filter layer and the purification box is sealed by the sealing plate.

[0016] As a further improvement to this technical solution, an auger is provided inside the extrusion cylinder, and multiple heating rings are fixedly provided on the outer wall of the extrusion cylinder.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This multi-extruder collaborative production equipment for cables uses a crushing mechanism to cut and crush the cable material with multiple cutters. The rotating shaft drives the conveying spiral blades to rotate, which guides the material in the feed pipe and avoids internal blockage caused by excessive material. This ensures that the cable material in the feed hopper is fed into the extrusion cylinder in an orderly manner, effectively guaranteeing the normal operation of the extrusion cylinder.

[0019] 2. This multi-extruder collaborative production equipment for cables is equipped with a purification mechanism that transports organic waste gas to the purification chamber. The organic waste gas in the purification chamber is adsorbed and purified by three filter layers to remove harmful substances and odors from the waste gas, thereby reducing the emission of organic waste gas into the ambient air and minimizing harm to the atmospheric environment and human health.
