Tubular product rolling device

Abstract

The invention relates to a tubular product rolling device. The tubular product rolling device comprises a rack, a motor arranged on the rack and a rotating shaft rotatably arranged on the rack. The motor drives the rotating shaft to rotate at a uniform speed, a sleeve is further rotatably connected on the rotating shaft in a sleeving manner, and a friction pair is formed between the inner circumference of the sleeve and the rotating shaft. With a tubular product being rolled, the actual rolling radius of the tubular product is increased gradually, the tubular product blocks rotation of the sleeve, and the sleeve and an elastic part slide relatively, that is, the rotating speed of the sleeve is lower than that of the rotating shaft, so that the rolling linear speed of the tubular product isconstant. The rolling linear speed of the tubular product is equal to an output speed of a first extruder, the tubular product is prevented from being deforming as a result of a too large tensile force, and follow-up normal production is guaranteed, so that a product part is relatively high in production quality.

Description

technical field [0001] The invention relates to the technical field of winding equipment, in particular to a pipe winding device. Background technique [0002] PVC is a low-cost resin material with good physical and chemical properties. After adding plasticizers, stabilizers and various performance additives to the formula, it can be made into a PVC hose with a bright appearance. It is widely used in Agricultural irrigation, household cleaning, industrial transmission of fluid media and pneumatic tools and other fields. [0003] Commonly used PVC reinforced hoses include inner and outer layers of PVC material, and a layer of polyester fiber mesh is wound between the inner and outer layers of PVC materials, and a negative pressure is formed through the vacuum forming head to make the inner and outer layers can be glued together tightly. [0004] The existing Chinese patent with the notification number CN105906981B discloses a method for preparing a high-temperature-resistan...

AI Technical Summary

Problems solved by technology

[0012] The above-mentioned existing technical solutions have the following defects: the working efficiency of the first extruder is constant, that is, the production and output line speed of the PVC inner pipe body is constant, and when the existing pipe material winding machine is used to wind the PVC inner pipe body , the rotation speed of the motor is constant, the PVC inner pipe body is gradually wound onto the roll, and the actual winding radius of the PVC inner pipe body gradually increases, that is, the linear speed of the PVC inner pipe body gradually increases, and the first extruder The output rate remains unchanged, causing the winder to pull the PVC inner pipe body, which in turn causes the PVC inner pipe body to deform, affecting the production quality of PVC reinforced hose
