[0002] PVC, that is, polyvinyl chloride, is a polymer formed by the polymerization of vinyl chloride monomer under the action of initiators such as peroxides and azo compounds or under the action of light and heat according to the free radical polymerization reaction mechanism. PVC materials have excellent corrosion resistance and can resist the erosion of most acids, alkalis, salts and other chemical substances. At the same time, it is also a material with good electrical insulation performance and can be used for the insulation layer of wires and cables. In addition, PVC materials also have excellent processing performance and are easy to be made into products of various shapes and specifications through processes such as injection molding, extrusion, and calendering. Moreover, they are relatively light and have a certain degree of softness, which is convenient for use and carrying.

The rotating seat is rotatably installed on the inner wall of the first bracket.

When the transmission shaft aligns with the transmission tubes and transmission grooves of the lower traction roller and the upper traction roller, release the limiting plate, and the transmission shaft slides into the transmission grooves of the lower traction roller and the upper traction roller by the elasticity of the first spring, and is limited by the limiting plate, thereby facilitating the replacement and installation of the lower traction roller, the upper traction roller and the auxiliary moving mechanism.

By the elasticity of the second spring, the second sliding bracket is pushed to slide on the auxiliary bracket, and then the auxiliary upper roller is pressed, so that the rotation of the auxiliary upper roller and the auxiliary lower roller assists in moving PVC hoses of different diameters.

[0013] Preferably, the detection mechanism includes a turntable, a plurality of bumps, and a proximity switch. It is rotatably installed on the outer wall of the auxiliary bracket. The turntable is connected to the auxiliary rotating seat. The plurality of bumps are evenly installed on the turntable.

The guide rod 53 is installed on the second sliding frame 52. The guide rod 53 is slidably installed on the auxiliary frame 51. The second spring 54 connects the auxiliary frame 51 and the second sliding frame 52;

[0032] The auxiliary moving mechanism 06 includes an auxiliary rotating seat 61, an auxiliary lower roller 62 and an auxiliary upper roller 63. The auxiliary rotating seat 61 is rotatably installed on the auxiliary frame 51. The auxiliary lower roller 62 and the auxiliary upper roller 63 are installed on the auxiliary rotating seat 61 through the installation mechanism 03, and the way that the auxiliary lower roller 62 and the auxiliary upper roller 63 are installed on the auxiliary rotating seat 61 through the installation mechanism 03 is the same as the way that the traction lower roller 22 and the traction upper roller 23 are installed on the rotating seat 21 through the installation mechanism 03;

[0033] The detection mechanism 07 includes a turntable 71, a plurality of bumps 72 and a proximity switch 73, and is rotatably installed on the outer wall of the auxiliary frame 51.

Push the second sliding frame 52 to slide on the auxiliary frame 51 through the elasticity of the second spring 54, and then press the auxiliary upper roller 63, so that the rotation of the auxiliary upper roller 63 and the auxiliary lower roller 62 assists in moving PVC hoses of different diameters. When the PVC hose moves, it drives the auxiliary lower roller 62 to rotate, and then drives the turntable 71 to rotate. When the proximity switch 73 detects that an electrical signal will be generated on the bump 72, and when the proximity switch 73 does not detect the bump 72, the proximity switch 73 does not generate an electrical signal, thus causing the proximity switch 73 to intermittently generate an electrical signal. When the electrical signal remains unchanged, it proves that the PVC hose has not moved.
