Thermocompression bonding wheel for drip irrigation belt

Abstract

The invention discloses a thermocompression bonding wheel for a drip irrigation belt. The thermocompression bonding wheel of the drip irrigation belt comprises an oil supply and distributing joint, a central shaft, an oil feeding pipe, a wheel strake, an oil channel baffle plate, a right side wheel flange, a left side wheel flange, a heat sealing pressing wheel, an external stainless steel protecting plate, a first joint, a second joint and a hose; the oil supply and distributing joint is fixedly connected to one end of the central shaft, and the other end of the central shaft is connected with a motor; the oil feeding pipe is positioned into an internal chamber of the central shaft; one end of the oil feeding pipe is connected with the oil supply and distributing joint while the other end of the oil feeding pipe is connected with a temperature control device; the wheel strake is arranged outside the central shaft in a sleeving way and is fixedly connected with the central shaft; a left annular groove and a right annular groove are respectively arranged on the edges of both sides of the wheel strake; the left side wheel flange and the right side wheel flange are respectively arranged in the left annular groove and the right annular groove, and moreover, the heat sealing pressing wheel is mounted in a clearance formed between the left side wheel flange and the right side wheel flange; and the heat sealing pressing wheel is arranged outside the wheel strake in the sleeving way. The thermocompression bonding wheel of the drip irrigation belt disclosed by the invention integrates the heating function and the extruding function, therefore, good effect of heating is achieved; and a copper-made heat sealing pressing wheel is adopted, by which the surface layer of a film can be prevented from being adhered to other layers.

Description

technical field [0001] The invention belongs to the technical field of drip irrigation, and in particular relates to a drip irrigation belt hot-press welding wheel. Background technique [0002] At present, in the field of drip irrigation technology, a flat extruder is usually used for the production equipment of the drip irrigation belt. When using a flat extruder to extrude a flat PE film to form a drip irrigation belt, it must go through processes such as wrapping, hot-press welding, etc. In the hot-press welding process, the stability of the process technology has an impact on the drip irrigation belt product Very big. The current hot-press welding methods mainly include ultrasonic cold welding technology. Although this technology is fast and convenient, the phenomenon of missing welding is very obvious when running at high speed; The technology is simple and the bonding effect is better, but all the extruded film layers are bonded together during the bonding process, ...

AI Technical Summary

Problems solved by technology

The current hot-press welding methods mainly include ultrasonic cold welding technology. Although this technology is fast and convenient, the phenomenon of missing welding is very obvious when running at high speed; The technology is simple and the bonding effect is better, but all the extruded film layers are bonded together during the bonding process, while the wrapping thin-walled drip irrigation tape only allows the outer two layers of film layers to be bonded together. Connected together, the outer innermost layer cannot be bonded with other layers. In addition, this technology does not have a heating device, so it is not suitable for bonding of wrapping thin-walled drip irrigation tape
