Super-long copper tube plastic wrapping machine with small specification

Abstract

The invention discloses a super-long copper tube plastic wrapping machine with small specification, comprising a tube inlet guide position and a tube outlet guide position which are respectively arranged at the front end and the back end of a machine frame, wherein a clamping delivery device, a preheating device, a plastic extruding machine and a cooling device are sequentially arranged between the tube inlet guide position and the tube outlet guide position, a roller rectification device is arranged between the tube inlet guide position and the clamping delivery device, a traction device is arranged between the cooling device and the tube outlet guide position, the speed of the traction device is synchronous to the speed of the clamping delivery device, and an automatic sawing device is arranged between the traction device and the tube outlet guide position and sequentially comprises a length counting coder, a clamping device and a sawing device. When the length counting coder counts to a set length, the clamping device clamps a copper tube wrapped with plastics and the sawing device automatically saws the clamped copper tube wrapped with the plastics. The invention has reasonable design, simple structure, convenient and practical operation and reliable work, greatly enhances the production, also improves the product quality, shortens the production period and lowers the production cost.

Description

technical field [0001] The invention relates to an automatic plastic wrapping machine for outer plastic packaging of copper pipes. Background technique [0002] With the development of society, the utilization rate of green and environmentally friendly new materials is getting higher and higher. Copper water pipes with long life and easy installation are also widely used in the construction of office facilities and residential buildings at home and abroad. In order to have a longer service life of the copper water pipe, a layer of polyvinyl chloride engineering plastic is wrapped on the outside of the copper water pipe by injection molding, so that the copper water pipe is protected. The plastic-coated pipes currently produced are all made of fixed-length hard copper pipes. Since the length of straight pipes can only be 6m, the length of plastic-coated copper pipes is generally about 6m, and the pipe diameter is generally above φ28mm; now The market demands plastic-coated c...
