Technical Field

[0001] This utility model relates to the field of pipe welding technology, specifically a polyethylene pipe welding heating device. Background Technology

[0002] In recent years, polyethylene pipes have been widely promoted and applied in industries such as water supply and gas supply due to their outstanding advantages such as economy and durability. Polyethylene pipes are lightweight, corrosion-resistant, and easy to install. While meeting engineering requirements, they can also reduce maintenance costs. With the widespread application of polyethylene pipes in various industries, the welding equipment technology that undertakes the fusion function of polyethylene pipes is also developing rapidly.

[0003] Most existing hot-melt welding equipment can only perform hot-melt treatment on matching pipes. When fixing pipes of different sizes, it is necessary to replace the clamps to achieve the fixed installation of the pipes. The whole operation process increases the production cost of the equipment and is also very inconvenient to use. Utility Model Content

Several rubber blocks are provided on the outer surface of the limiting block, and the several rubber blocks are arranged in an annular array on the outer surface of the limiting block. A drive motor is fixedly provided on one side of the connecting shaft, and a lead screw is rotatably provided on the side of the connecting shaft away from the drive motor. The drive end of the drive motor is fixedly connected to one end of the lead screw through a coupling, and the lead screw thread passes through the connecting block.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a drive motor to rotate a lead screw, which moves a connecting block on its sleeve surface.

A rotating shaft 42 is rotatably mounted on one side of the fixed ring 23. A rotating rod 43 is fixedly sleeved on the outer surface of the rotating shaft 42. A connecting sleeve 44 is rotatably mounted inside the annular frame 41. The rotating rod 43 passes through the connecting sleeve 44 and slides against the inner surface of the connecting sleeve 44. A limiting block 45 is fixedly mounted at the other end of the rotating rod 43. A U-shaped block 411 is fixedly mounted on the outer surface of the annular frame 41. A connecting block 48 is rotatably mounted on one side of the U-shaped block 411. A connecting shaft 49 is rotatably mounted on one side of the fixed ring 23.

The drive end of the drive motor 5 is fixedly connected to one end of the lead screw 52 via a coupling drive shaft. The lead screw 52 is threaded through the connecting block 48. When the drive motor 5 is started, the drive end drives the lead screw 52 to rotate via the coupling drive shaft. The lead screw 52 can move the connecting block 48 on its sleeve surface. The moving connecting block 48 can cause the ring frame 41 to rotate. By rotating the connecting sleeve 44 inside it and the rotating shaft 42 set on one side of the fixed ring 23, the rotating rod 43 can rotate. The rubber block 46 on the outer surface of the limiting block 45 contacts the pipe, thereby limiting the pipe and clamping and fixing pipes of different models. A fixed housing 51 is fixedly provided on one side of the connecting shaft 49. The drive motor 5 is installed inside the fixed housing 51 to protect the drive motor 5. An anti-detachment block 6 is fixedly provided at the end of the lead screw 52 away from the drive motor 5 to prevent the lead screw 52 from detaching from the connecting block 48. The lower surface of the processing base 1 is fixedly provided with four support legs 7. The four support legs 7 are symmetrically arranged on the lower surface of the processing base 1 to support the equipment. The processing base 1 is fixedly provided with opposing slide rails 2, and an electric slider 21 is slidably provided in the opposing slide rails 2. The electric slider 21 is fixedly connected to the second fixed frame 22, which can make the two second fixed frames 22 move in opposite directions. The outer surface of the limiting block 45 is provided with a number of rubber blocks 46. The number of rubber blocks 46 are arranged in a ring array on the outer surface of the limiting block 45. The multiple rubber blocks 46 can stably limit the pipe.

[0016] Working principle: When in use, this utility model can be inserted into the fixing ring 23 through a pipe. Then, the drive motor 5 can be started to drive the lead screw 52 to rotate through the coupling drive shaft. The lead screw 52 can move the connecting block 48 on its sleeve surface. The moving connecting block 48 can make the ring frame 41 rotate. By rotating the connecting sleeve 44 inside it and the rotating shaft 42 set on one side of the fixing ring 23, the rotating rod 43 can be rotated. The rubber block 46 on the outer surface of the limiting block 45 contacts the pipe, thereby limiting the pipe and clamping and fixing pipes of different models. By activating the opposing slide rail 2, the two electric sliders 21 can be moved towards the center, and the electric sliders 21 can drive the clamped pipe to move towards the center. By activating the heating tube 13, the end of the pipe can be heated. Activating the opposing slide rail 2 again can drive the two electric sliders 21 to move the clamped pipe towards the center again. When the two pipes come into contact with each other, they can be fused together.
