Description

Technical Field

[0001] The invention relates to the technical field of polyethylene composite pipe production equipment, and in particular to automatic winding equipment for polyethylene composite pipe production. Background Art

[0002] Polyethylene pipe is a commonly used plastic pipe made from a highly crystalline, non-polar thermoplastic resin. It has a wide range of applications, including electrical wiring, water supply pipes, and drainage pipes. To expand its applications, further improvements are needed to its performance. To increase its overall strength, steel wire is repeatedly wrapped around the pipe to create a high-strength polyethylene composite pipe with an outer steel mesh layer. To improve the thermal insulation of polyethylene pipe, unidirectional tape is wrapped around the pipe's exterior, creating a thick insulation layer in the middle with joints retaining their original dimensions at both ends. Current winding equipment is primarily based on improved steel wire winding equipment. The polyethylene pipe is rotated by a motor, while the unidirectional tape is fixed in position. A lever adjusts the tape's direction and angle, resulting in variable angle adjustment. This method results in wrinkles between the tape wraps and loose seams, which can lead to the tape's insulation shedding during use. Gluing and cutting are both performed manually, resulting in a low degree of automation, high production costs, and low efficiency. Therefore, there is an urgent need to design an automatic winding equipment for the production of polyethylene composite pipes to solve the problems of poor winding quality, low degree of automation and low production efficiency of the existing polyethylene composite pipes with thermal insulation layers.

The operating method of the automatic winding equipment for producing polyethylene composite pipes according to any one of claims 1 to 6, characterized in that: The following steps are involved: 1) First, set the winding angle and winding spacing of the belt on the polyethylene tube on the electronic control system, that is, determine the position of the proximity switch to start working and the distance limited by the laser rangefinder; 2) Manually clamp one end of the polyethylene tube into the limiting groove of baffle 1, and use the remote control to control the cylinder rod of the clamping cylinder to extend, so that baffle 2 presses against the other end of the polyethylene tube; 3) Start the lifting cylinder to control the two semicircular sleeves to descend. The cylinder rod of the sleeve cylinder extends to control the two semicircular sleeves to close inward. The glue on the brush is applied to the outer wall of the polyethylene tube. The sleeve cylinder and the lifting cylinder control the semicircular sleeves to return to their original position. 4) Determine the tightness of the tape by adjusting the screw and the tape clamping cylinder according to the width and thickness of the tape, and stick the head of the tape to the edge of the polyethylene tube where the tape needs to be wrapped; 5) Start the equipment switch, the rotary motor drives the polyethylene tube to rotate one circle, the two drive motors simultaneously drive the clamping cylinder and the rotary motor to the specified proximity switch position, and the shaft motor drives the rotary motor to rotate, so that the rotary motor, polyethylene tube and clamping cylinder remain coaxial, and the polyethylene tube continues to rotate. At the same time, the moving motor drives the tape box to move, so that the tape is wound around the polyethylene tube at a set angle. When the tape is wound to the edge of the winding tape set on the other side of the polyethylene tube, the drive motor drives the polyethylene tube to reset to the horizontal direction and perpendicular to the tape. The polyethylene tube rotates one circle, and the two drive motors simultaneously drive the clamping cylinder and the rotary motor to the specified reverse proximity switch position. The polyethylene tube continues to rotate and starts reverse winding, and the tape is wound back and forth in sequence; 6) After the polyethylene tube is wound, turn off the equipment switch, start the lifting cylinder to control the two semicircular sleeves to descend, extend the cylinder rod of the sleeve cylinder to control the two semicircular sleeves to close inward, cut the tape with a cutter, apply the glue on the brush to the outer layer of the tape to stick and fix it, control the semicircular sleeve to reset with the sleeve cylinder and the lifting cylinder, retract and reset the clamping cylinder, remove the composite tube, replace the new polyethylene tube and repeat steps 1) to 6).
