Non-joint automatic connecting device for PVC pipes

Abstract

The invention discloses a non-joint automatic connecting device for PVC pipes. The device comprises a main body box, a left-right through PVC pipe through cavity is formed in the main body box, a clamping box sliding cavity communicates with the outer side of the PVC pipe through cavity, a guide ring moving cavity communicating with the PVC pipe through cavity inwards is formed in the right side of the clamping box sliding cavity, an annular gear cavity communicating with the PVC pipe through cavity inwards is formed in the right side of the guide ring moving cavity; the softening compaction box rotates to achieve automatic heating softening and guarantee even softening at the same time, the guide rod plays a role in guiding and assists a left PVC pipe in being inserted into a right softened PVC pipe, automatic inserting connection is achieved, after inserting is completed, the guide rod is automatically pulled out to prevent interference with pulling out of the PVC pipes, meanwhile, acompaction wheel extends out and rotates to compact the softened PVC pipe, so that the risk of scalding possibly caused by manual operation is avoided while tight connection of the softened PVC pipeis ensured.

Description

technical field [0001] The invention relates to the related technical field of PVC pipes, in particular to a non-joint automatic connection device for PVC pipes. Background technique [0002] In order to take care of the transportation and storage of PVC pipes, the length of a single piece is usually not long, and in some cases it needs to be connected and used together, while the traditional PVC pipe connection mostly uses joints for bonding or flange connection, but the use of joints will increase the diameter of the PVC pipe , which is not conducive to the laying in some narrow scenes. At the same time, the purchase of the joint itself will increase the cost. On the other hand, there is also a way to use heated PVC pipes to soften them and then connect them. However, both heating and connection insertion are done manually. Insertion It is more difficult, and the heated PVC pipe is easy to burn the workers. Contents of the invention [0003] Aiming at the deficiencies o...
