Description

Technical Field

[0001] The present application relates to the technical field of PVC pipe processing, and in particular to a PVC pipe hot-melt butt joint device. Background Art

[0002] Since the lengths of pipelines are different during laying, PVC pipes need to be cut and butt-jointed according to the required length during the actual installation process. Hot-melt butt-jointing is a method used to butt PVC pipes. The principle is to use a heating plate to melt the ends of two sets of PVC pipes, and then fit the ends of the two sets of PVC pipes together, allowing them to bond naturally after cooling.

[0003] After searching, the Chinese patent number is CN202211731403.4, a PVC pipe hot-melt butt joint device with a dustproof structure, including a base frame, the base frame is welded by four parallel square cylinders; a fixed frame, the fixed frame is fixedly welded on the upper side of the front end of the base frame; a movable frame, the movable frame is slidably connected to the rear side of the upper end of the base frame, and the movable frame is arranged in parallel with the fixed frame; a clamping plate, the clamping plate is provided with four groups in total, and the four groups of clamping plates are respectively arranged on the upper left and right sides of the fixed frame and the movable frame, and the clamping plates opposite to each other on the front and rear sides can slide back and forth, and the clamping plates on the left and right sides of the front end can slide left and right. The present invention uses a threaded connection between a bidirectional screw and a first sliding seat, so that the clamping plates on the left and right sides can move synchronously in opposite directions, so as to realize the opposite movement of the two groups of PVC pipes close to the fitting heating plate or docking, and because the two groups of PVC pipes move synchronously, the movement efficiency is higher, the docking speed is faster, and the operation is convenient.

[0004] However, the above scheme still has defects. When the heating plate heats the end of the PVC pipe until it melts, the bidirectional screw is rotated to make the ends of the two groups of PVC pipes slightly move apart, and then the handle is lifted to make the heating plate enter the fixed baffle and the rotating baffle, and the handle is lifted to the upper side of the guide frame and rotated ninety degrees so that it is stuck in the groove at the upper end of the guide frame. Then, the bidirectional screw is rotated in the opposite direction to make the ends of the two groups of PVC pipes come together to achieve the docking of the pipes. The heating plate is lifted manually, and the process of manually operating the bidirectional screw is too time-consuming and laborious. In addition, the PVC pipe is clamped by two left and right clamps, and the two clamps cannot be released until they touch the PVC pipe, resulting in too long time for manual lifting of the PVC pipe, increased manual labor, and a bad user experience.

After a certain period of time, the second hydraulic cylinder will work to separate the arc-shaped clamping plate from the base, and finally the PVC pipe that has been docked can be removed. The PVC pipe hot-melt docking device uses an electric control cabinet to control the first hydraulic cylinder, the heating plate, the motor and the second hydraulic cylinder, that is, there is no need for manual operation of the heating plate and the bidirectional screw, which saves time and effort. In addition, two clamping rings are used to clamp and fix the PVC pipe.
