Problems solved by technology

[0003] Plastic welding refers to the connection method that melts the contact surfaces of two plastic parts at the same time by heating, so that they are combined into a whole; at present, most of the welding between the nozzles of plastic pipes adopts the method of hot-melt butt joint of plastic pipes 1. Heat the welding interface of the two plastic pipes to a viscous state with a heating plate, then remove the heating plate; then manually apply opposing pressure to the two plastic pipes, and cool and solidify under this pressure state to form a firm connection; In the prior art, if the welding round holes on the two plastic pipes cannot be positioned accurately during the process of manual pressure, the welding will fail and cause defective products; and when using a heating plate that can only be heated on one side, The two plastic pipes cannot be heated at the same time. In this state, during butt welding, one of the two plastic pipes will be heated first. After the heating is completed, in the process of heating the other plastic pipe, if the time If it is too long, the previously heated plastic pipe will solidify, resulting in welding failure

Abstract

The invention belongs to the technical field of plastics, and particularly relates to a plastic tube hot-melting welding machine. The plastic tube hot-melting welding machine comprises a mounting shell, a return spring, a hot-melting block, driving arms, a limiting plate, a driving mechanism, a trigger mechanism and a driving swing rod. The plastic water tube welding machine firstly controls the driving swing rod to swing downward so that a fuser can heat two plastic tubes, and then controls the driving swing rod to swing upward so that the two driving arms can drive the plastic tubes to firstmove to both sides, and then the driving swing rod can swing upward to control the hot-melting block to move upward; when the hot-melting block is completely moved to the upper side, the driving swing rod is driven to swing downward again, and the driving swing rod swings to control the two driving arms to drive the plastic tubes to move, and finally the contact pressure is applied to weld the two plastic tubes together; the situation that tube openings cannot be aligned because the two plastic tubes are artificially stressed, the welding effect is influenced, and leakage of the welding is caused is reduced; and meanwhile, the situation that the welding effect is influenced due to the curing of originally heated plastic tubes due to two times of heating is prevented.

Description

[0001] Technical field [0002] The invention belongs to the technical field of plastics, in particular to a plastic pipe hot-melt welding machine. Background technique [0003] Plastic welding refers to the connection method that melts the contact surfaces of two plastic parts at the same time by heating, so that they are combined into a whole; at present, the welding between the nozzles of plastic pipes mostly adopts the method of hot-melt butt joint of plastic pipes 1. Heat the welding interface of the two plastic pipes to a viscous state with a heating plate, then remove the heating plate; then manually apply opposite pressure to the two plastic pipes, and cool and solidify under this pressure state to form a firm connection; In the prior art, if the welding round holes on the two plastic pipes cannot be positioned accurately during the manual pressure application, the welding will fail and cause defective products; and when using a heating plate that can only be heated on...
