Pipe maker for all-plastic hose forming

Abstract

The present invention discloses a pipe maker for all-plastic hose forming. The pipe maker comprises a frame. The pipe maker is characterized in that: the pipe maker further comprises a sheet material conveying apparatus forming a fixed connection on the frame, a sheet material overlapping apparatus, a hose forming apparatus, an interface welding apparatus, a hose conveying apparatus and a hose cutting apparatus. The sheet material overlapping apparatus is arranged below the sheet material conveying apparatus. The sheet material conveying apparatus is arranged in front of the hose forming apparatus. The hose forming apparatus is arranged in front of the interface welding apparatus and the hose conveying apparatus. The hose interface welding apparatus is arranged above the hose conveying apparatus. The hose cutting apparatus is arranged on the rear of the hose conveying apparatus. According to the present invention, the pipe maker for the all-plastic hose forming has high automaticity; an aerodynamic and servo system is adopted; the actions are precise and smooth; the operation adopts a man-machine interface; the parameter setting can be completed on the interface; the pipe maker has functions of cumulative shift production, fault displaying, work state displaying, automatic and manual switching and flexible operation.

Description

technical field [0001] The invention relates to a pipe making machine, in particular to a pipe making machine used for forming all-plastic hoses. Background technique [0002] All-plastic hose is currently the packaging form commonly used in industries such as daily necessities, cosmetics, food, and pharmaceuticals. The annual demand is huge. Improving its production efficiency and reducing its production cost are of great significance to industries such as daily necessities, cosmetics, food, and pharmaceuticals. . At present, the existing domestic pipe-making machines for forming all-plastic hoses are relatively old. At the same time, the degree of automation of the equipment is low, and manual operation is often required, resulting in low production efficiency and increased production costs, which cannot meet the requirements of modern production for production automation, high efficiency and low cost. [0003] The Chinese patent No. 0021996.1 discloses an aluminum-plast...

AI Technical Summary

Problems solved by technology

The above-mentioned aluminum-plastic composite hose pipe making machine has the following disadvantages: when in use, the paper pressing mechanism puts the soft roll material on the stocker, and the soft roll material is sent to the pressing device through the moving mechanism. During the feeding process, there are many mistakes in feeding soft coils, which greatly reduces the production efficiency of the hose making machine; moreover, the bent soft coils are easy to get stuck in the forming mechanism, causing the hose making machine to stop, and even damage the hose Pipe making machine, the stuck soft coiled pipe becomes waste product, which increases the production cost

However, this device has a low degree of automation and cannot perform automatic sheet lapping and roll changing. The use of multiple short belt conveying devices is likely to cause disconnection of hose friction and affect its production quality. At the same time, its heating transducer adopts The form of heat conduction can only heat a short distance, which affects the welding quality of its interface

[0005] Ordinary high-frequency heating melts the outer surface of the aluminum-plastic hose, leaving deep or shallow welding marks on the surface of the hose, resulting in poor appearance of the product, and easily causing burns and wrinkles on the surface of the hose, resulting in a lot of hose waste

At the same time, the ordinary high-frequency induction current cannot directly heat the all-plastic hose

[0006] In the production process of hose forming, there are certain requirements for the thickness of the welding joint. The welding of the overlapping joint is double-layer thickness. After welding, it should be as close as possible to the thickness of a single layer. This requirement must be met regardless of internal welding or external welding. However, the previous hose forming machines did not consider this requirement, resulting in a decrease in the quality of the hose

[0007] In short, the equipment for forming all-plastic hoses in the prior art cannot meet the needs of modern processing and production
