Bend winding device with three-section heating function

Abstract

The invention discloses a bend winding device with a three-section heating function. The bend winding device comprises a winding disc, a drive guide rail, a centering device, a winding disc temperature control device and outer flame heating devices. The winding disc is arranged at the middle position of the drive guide rail. The drive guide rail is arranged at the bottom position and is in a sector shape. The winding disc is arranged at the middle position of the drive guide rail and fixedly arranged on the drive guide rail. The centering device is arranged in the winding disc and fixedly arranged in the winding disc. The wining disc temperature control device is arranged on the inner side of a connecting plate and fixed to the connecting plate. The two outer flame heating devices are arranged, one outer flame heating device conducts preheating, the other outer flame heating device conducts tail end heating, the outer flame heating device for preheating is fixedly arranged at the left end of the drive guide rail, and the outer flame heating device for tail end heating is arranged at the right end of the drive guide rail. According to the bend winding device with the three-section heating function, the winding quality of an antiseptic thermal shrinkage rubber belt is greatly improved, the work efficiency is improved, the labor intensity is lowered, and the service life of a bend is prolonged.

Description

technical field [0001] The invention belongs to the technical field of elbow wrapping heating technology, and in particular relates to an elbow winding device with three-stage heating function. Background technique [0002] Bend pipe is a typical asymmetric part, and the processing difficulty of bent pipe is more difficult than that of straight pipe. Equipment oil, hydraulic system application. [0003] In order to improve the service life of the elbow, a layer of heat-shrinkable anti-corrosion tape is usually wrapped on the surface of the elbow to resist the corrosion of the elbow by humid air and corrosive liquid in the environment. The anti-corrosion heat-shrinkable tape has a three-layer structure, the inner layer is a two-component solvent-free epoxy primer coated on the surface of the elbow, the middle layer is an anti-corrosion hot-melt adhesive with excellent performance, and the outer base material is low-density polyethylene ; As the adhesive of anti-corrosion he...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides an elbow winding device with three-stage heating function, which has scientific and reasonable design, simple structure, high winding precision, and good use effect; it can solve the problem that the temperature cannot be controlled during the heating process of the elbow, If the temperature is too high, the anti-corrosion heat-shrinkable tape will be scorched, and if the temperature is too low, the melt will not overflow. At the same time, it also solves the problem of low efficiency and high labor intensity of manual heating, which is easy to cause deviation and winding of the anti-corrosion heat-shrinkable tape. The problem of not being tight, the surface of the anti-corrosion heat shrinkable tape is uneven, and the problem of affecting the service life of the elbow
