Description

Technical Field

[0001] The utility model relates to the technical field of thermoplastic pipe production, in particular to a traction discharging device for thermoplastic pipes. Background Art

[0002] Thermoplastic pipes, also known as heat shrinkable pipes or heat shrinkable sleeves, are mainly used for the insulation protection of wires, cables and wire terminals. The main uses of heat shrinkable pipes include providing an insulating envelope for bare metal wires, protecting wires from abrasion and environmental pollution. It can also be used to repair the insulation layer on wires or bundle wires together to form a cable inlet seal and provide environmental seal protection.

[0003] In the production process of thermoplastic pipes, the thermoplastic pipes are processed through feeding equipment, extrusion equipment and cooling equipment. For the feeding and transfer of thermoplastic pipes, a traction device is usually used. The traction device is usually arranged in front of the extrusion outlet of the extruder or at the final discharging stage. At present, after the traction discharging device conveys the pipe material out of the material, it directly falls freely into the stacking box for stacking. During the free fall, the pipe material is easily damaged.

[0004] After retrieval, a Chinese patent discloses a traction discharging device for thermoplastic pipes (authorization publication number CN217891785U), which includes a working frame. A traction discharging device and a material receiving mechanism are successively arranged on the working frame from front to back. The material receiving mechanism includes a bracket. The bracket is installed on the rear side of the working frame. A rotatable rotating cylinder is arranged on the rear side of the bracket. A driving motor is also arranged on the rear side of the bracket. The driving motor drives the rotating cylinder to rotate. A rotating shaft is arranged in the rotating cylinder. The rotating shaft is coaxially driven with the rotating cylinder. A material receiving plate is arranged on the rotating shaft. The material receiving plate is used for receiving the plastic pipe after discharging. Although this patented technology can solve the problem that the traction discharging device conveys the pipe material out of the material and then directly falls freely into the stacking box for stacking, and it is easy to cause damage to the pipe material during the free fall.

[0005] However, there are still some disadvantages in the actual use of the above device. The more obvious one is that the above plastic pipe is received by the material receiving plate after discharging. After receiving, the plastic pipe is clamped and fixed by a first clamping hand and a second clamping hand. Then, the driving motor drives the rotating cylinder to rotate downward, so that the material receiving plate, the first clamping hand and the second clamping hand face downward, and the first clamping hand and the second clamping hand are loosened, so that the plastic pipe is placed at the stacking position. However, the above operation cannot continuously discharge the thermoplastic pipe, reducing the production efficiency of the thermoplastic pipe. Summary of the Utility Model

A servo motor one is fixedly installed on the outside of one of the traction discs, and a replacement mechanism is arranged inside the traction disc and within the inner circle of the rotating roller.
