Automatic polypropylene random (PPR) pipe assembly hot-melt welding device

Abstract

The invention discloses an automatic polypropylene random (PPR) pipe assembly hot-melt welding device which comprises a base, wherein a portal frame is arranged above the middle of the base; a hot melt machine is arranged on a beam; a hot-melt die head is arranged below the hot melt machine; pipe transfer mechanisms are symmetrically arranged on the front and rear sides of the portal frame; the pipe transfer mechanisms comprise sliding seats capable of moving back and forth; two groups of pipe assembly clamping mechanisms are arranged on the left and right sides of the sliding seats in parallel; down pressing pipe mechanisms are arranged on the sliding seats between the two groups of pipe assembly clamping mechanisms; the pipe assembly clamping mechanisms comprise positioning blocks and telescopic cylinders; the positioning blocks are arranged at one ends, which are close to the portal frame, of the sliding seats; the telescopic cylinders are arranged at one ends, which are far away from the portal frame, of the sliding seats; piston rods of the telescopic cylinders are connected with top pipe columns of the positioning blocks. The invention has the beneficial effects that the hot-melting and fitting operations of the pipe assemblies can be mechanically completed, the hot-melting effect is good, the fitting is accurate, high sealing property is guaranteed, the manual labor is saved, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to an automatic hot-melt welding device for a PPR pipe assembly. Background technique [0002] PPR pipes are widely used in industrial and residential buildings, sanitary drinking water supply and hot water heating, and have been widely used and popularized in people's real life. The long-term working temperature of the PPR pipe cannot exceed 70°C; the length of each section is limited, and it cannot be bent for construction. If the pipe laying distance is long or there are many corners, a large number of joints will be used in the construction. The hot-melt technology of PPR pipe can make There is a good seal between the tubes to ensure that the tubes are not air-tight. But now it is generally used to manually heat-melt the PPR pipe, the heat-melting effect is poor, and the work efficiency is relatively low. Contents of the invention [0003] In order to solve the above technical deficiencies, the present invention provides a...
