In order to meet the customer's efficient production technology needs, it is necessary for us to develop an automated equipment for it, which is convenient for automatic hot-melt bonding of segmented HDPE pipes and automatic reeling to provide customers with production efficiency. Utility Model Content

The clamping cylinder clamps the tube material in the tube material box, and under the drive of the lifting cylinder and the feeding cylinder, a single tube material is clamped and fed to the automatic heating welding assembly.

[0007] The automatic heating and welding assembly receives the pipe material fed at a uniform speed, and includes an electric heater, a hot melt sheet and a cooling fan. The hot melt sheet is heated by the electric heater, and the horizontal cylinder arranged on the slide pulls the automatic heating and welding assembly to move the hot melt sheet to the upper part of the fed pipe material, and makes the hot melt sheet tangent to the upper end surface of the pipe, so as to heat and soften the upper part of the pipe material by hot melting.

[0008] The automatic rotating coil assembly includes a pipe reel, a rotating motor, a pipe reel, a pushing wheel pushed by a pushing cylinder, and an auxiliary wheel. The pipe reel is provided with an inner diameter disk and an outer diameter disk. The inner diameter disk is used for winding the pipe material, and the outer diameter disk is used for pushing the rolled pipe material to be unloaded. After the pushing wheel is lifted up, it clamps the pipe material in the opposite direction to the auxiliary wheel, and driven by the rotating motor, the rotating disk rotates at a constant speed, so that the pipe material is spirally rotated around the outer periphery of the inner diameter disk set on the rotating disk for one circle, and the hot-melt pipe material at the upper end is radially bonded to the inner diameter disk, and after the protected pipe material is coiled into a circle, it is hot-melt bonded to the upper end of the pipeline of the second circle.

[0009] Furthermore, the twist wheel is driven to rotate by the feed motor, and cooperates with the driven wheel tangentially matched below to twist the pipe material inserted from the feed port and feed it to the limit port at a uniform speed.

[0010] Furthermore, a plurality of pushing and unloading cylinders are arranged on the inner side of the outer diameter disk of the pipe reel, and the pushing and unloading cylinders synchronously perform horizontal pushing actions on the outer diameter disk and push the rolled pipe material to be unloaded.

[0011] Furthermore, a protective rod is provided on the outer side of the pipe reel, and the protective rod is used to protect the rolled pipe material so as to ensure a stable posture for unloading.

[0012] Furthermore, the feed motor is positioned by the feed frame and cooperates with the slide rail slot vertically arranged on the feed frame to realize vertical lifting and lowering action, and the vertical displacement is controlled by the adjusting bolt to ensure the stability of the pressing force of the twist wheel and the driven wheel to press the pipe material.

[0013] The beneficial effects of the utility model are:

[0014] The catheter coil machine uses an automatic clamping and feeding component to feed the pipe material to the automatic heating and welding component at a stable and uniform speed. The hot melt sheet heat-melts the upper end of the pipe, and cooperates with the automatic rotating coil component to coil the pipe material into a circle, and continuously coils to form a complete pipe material coil, which is highly practical.
