Description
Technical Field
[0001] The invention relates to the technical field of high-pressure hose production, in particular to a core-removing and pressure-testing integrated machine for manufacturing high-pressure hoses using recycled plastics. Background Art
[0002] In the production process of high-pressure hoses, traditional processes usually adopt a step-by-step operation method, including wire winding, plastic film coating, coating treatment, core removal and pressure testing. These processes often require a lot of manual operation, which not only has low production efficiency, but also easily leads to unstable product quality due to human factors. In addition, the raw materials used in traditional processes are mostly new plastics, which are costly, and fail to make full use of recycled plastic resources, failing to meet the needs of green manufacturing and sustainable development.
[0003] In the production of traditional high-pressure hoses, the bonding strength between steel wire and plastic film mainly relies on simple mechanical winding, lacking effective coating treatment and inner wall strengthening means, resulting in insufficient pressure resistance, wear resistance and corrosion resistance of the hose. At the same time, the coating liquid in the traditional process is sprayed unevenly, and problems such as missing coating or bubbles are prone to occur, which affects the sealing and service life of the hose. In addition, the core removal and pressure testing processes usually require separate equipment to complete, which increases the complexity and cost of the production line, and it is difficult to achieve real-time quality inspection, resulting in a high defective rate. In terms of environmental protection, the acidic gas generated by the pickled steel wire and the volatile organic compounds in the coating liquid in the traditional process have not been effectively treated, which can easily cause pollution to the environment. For this reason, we propose a core removal and pressure testing integrated machine for making high-pressure hoses using recycled plastics. Summary of the invention

The second spring 549 resets the mounting block 548 through its own elastic force. The air pump 533 at the upper end of the second fixed plate 521 is started, and the input port of the air pump 533 sucks in air through the first exhaust pipe 534. The steel wire 6 will be pickled before use to remove some impurities, and the acid gas in the installation sleeve 4 is absorbed by the first exhaust pipe 534, and then adsorbed by the activated carbon adsorption box 535, and then the air flow is output through the exhaust pipe 540. The output air flow quickly dries the inner wall of the hose to solidify the coating on the inner wall, and the air flow is used to spread the coating liquid more evenly. When the first exhaust pipe 534 inputs air flow, the air flow enters the fixed sleeve 536 and drives the second blade 537 to rotate through the air pressure, and the second blade 537 drives the rotating plate 538 to rotate, and the rotating plate 538 drives The L-shaped brush 539 is driven to rotate, and the L-shaped brush 539 passes through the gap of the cleaning groove 519 to clean the outside of the steel wire 6. Some impurities remaining in the steel wire 6 are collected by the L-shaped design of the L-shaped brush 539. After the L-shaped brush 539 is aligned with the collecting tube 544, the output shaft of the first electric telescopic rod 52 drives the fixed connecting rod 542 to move, and the fixed connecting rod 542 drives the second exhaust pipe 543 to slide into the collecting tube 544. The second exhaust pipe 543 sucks the impurities collected by the L-shaped brush 539 into the collecting tube 544 through the airflow, and the third electric telescopic rod 545 is started to drive the cleaning brush 546 to move in the collecting tube 544, and the impurities inside the collecting tube 544 are pushed into the collecting tank 547 for centralized collection.
