AI Technical Summary
During the existing plastic pipe forming process, the bottom area of the plastic pipe is difficult to be fully cooled, resulting in a temperature difference, which in turn causes the plastic pipe to deform when cooling.
A plastic pipe forming cooling device was designed. Utilizing a water distributor and an air distributor structure, water is sprayed through the first circular ring to evenly cool the surface of the plastic pipe. The meshing of the gear and rack allows the water to repeatedly contact the surface of the plastic pipe. The arc-shaped distributor and spherical structure are combined to expand the water flow range and enhance the cooling effect. Meanwhile, a collection box is used for water resource recovery and impurity filtering.
It achieves uniform cooling of the plastic pipe surface, reduces deformation caused by temperature differences, improves cooling effect, and enhances water resource recycling and equipment stability.

At this time, the rack 23 will be reset under the elastic force of the spring 24. When the gear 22 rotates to mesh with the rack 23, the position of the rack 23 is the initial meshing position, so that the gear 22 and the rack 23 will mesh again, and the first ring 17 will also reciprocate with the rack 23; during normal operation, the rack 23 will come into contact with the positioning block 3. When the meshing of the rack 23 and the gear 22 is completed, the rack 23 will be reset under the elastic force of the spring 24 until the rack 23 comes into contact with the positioning block 3. At this time, the position of the rack 23 is the initial position meshing with the gear 22; when the water flow passes through the first ring 17 and is ejected from the first circular hole 111, the water flow will reach the surface of the diverter plate 42. Because the surface of the diverter plate 42 is an arc structure, the water flow The water will flow out from both sides of the diverter plate 42, increasing the flow range of the water flow; if the plastic tube comes into contact with the fixed rod 4 during the transmission process, the plastic tube will first come into contact with the ball 5, and the ball 5 will rotate under the action of friction, reducing the damage to the plastic tube caused by friction.
