Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipeline cooling, in particular to a plastic pipeline cooling device. Background Art

[0002] Plastic pipes are the general name for pipes made of plastic materials, which are connected by pipes, pipe fittings, valves and other connectors. Plastic pipes have the characteristics of light weight, sanitation and safety, small water flow resistance, energy saving, metal saving, improvement of living environment, long service life, safety and convenience, etc. Therefore, they are favored by the pipeline engineering industry. In the process of plastic pipe production, cooling devices are usually used to help plastic pipes cool down;

[0003] When existing cooling devices cool down plastic pipes, they generally spray coolant on the surface of the plastic pipes. However, since the plastic pipes are placed on a workbench, the coolant cannot contact the lower end of the plastic pipe. Since the lower end of the plastic pipe cannot contact the cooling coolant, its cooling speed will be significantly slower than the part that can directly contact the coolant. This will not only cause uneven cooling of the entire pipe, affecting the performance and quality of the pipe, such as causing problems such as uneven stress and different shrinkage rates of the pipe, but also, if the lower end cannot be effectively cooled, the lower end of the pipe will be damaged due to excessive temperature, and will melt and deform.

[0004] Therefore, we proposed a plastic pipe cooling device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1-4 As shown, a plastic pipe cooling device includes a cooling table 1, a water tank 2 is fixedly connected to the center of the upper end surface of the cooling table 1, a mounting frame 3 is fixedly connected to the upper end surface of the cooling table 1, a water pipe 4 is fixedly connected to the side wall of the water tank 2, a shunt pipe 5 is fixedly connected to the end of the water pipe 4 away from the water tank 2, the shunt pipe 5 is fixedly connected to the mounting frame 3, and a nozzle 6 is fixedly connected to the end of the shunt pipe 5 away from the water pipe 4, auxiliary rollers 7 are symmetrically arranged in the cooling table 1, and a pipe body 8 is placed between the auxiliary rollers 7.

[0025] In this embodiment, Figure 2 As shown, transverse grooves 10 and vertical grooves 11 are symmetrically provided on both sides of the cooling table 1, and moving blocks 13 are slidably connected in the transverse grooves 10. A rotating shaft 12 is rotatably connected to the moving blocks 13. The rotating shaft 12 is fixedly connected to the auxiliary roller 7. The outer surface of the rotating shaft 12 is fixedly connected to a main pulley 14, and a belt 15 is sleeved between the main pulleys 14.

[0026] In this embodiment, Figure 2 As shown, the side of the belt 15 away from the main pulley 14 is transmission-connected with an auxiliary pulley 18, the side of the auxiliary pulley 18 away from the cooling table 1 is fixedly connected with a drive shaft 17, the end of the drive shaft 17 away from the auxiliary pulley 18 is fixedly connected with a drive motor 16, the lower end of the drive motor 16 is fixedly connected with a support plate 19, and the support plate 19 is slidably connected in the vertical groove 11.

[0027] In this embodiment, Figure 2 As shown, there are lifting blocks 20 vertically slidably connected in the vertical grooves 11, one of the lifting blocks 20 is fixedly connected to the upper end surface of the support plate 19, and the lifting blocks 20 are fixedly connected to a cylinder 22 on the side close to the auxiliary roller 7. The outer surface of the cylinder 22 is symmetrically rotatably connected to a connecting rod 21, and the end of the connecting rod 21 away from the cylinder 22 is rotatably connected to the outer surface of the rotating shaft 12.

[0028] In this embodiment, Figure 3 and Figure 4 As shown, the end of the cylinder 22 away from the lifting block 20 is rotatably connected to a lifting plate 23, and the end of the lifting plate 23 away from the connecting rod 21 is rotatably connected to a moving frame 24. The moving frame 24 is horizontally slidably connected to the upper end surface of the cooling table 1. During the movement of the moving frame 24, the lifting block 20 can be pushed to rise and fall through the lifting plate 23 and the cylinder 22.

[0029] In this embodiment, Figure 4 As shown, a threaded rod 25 is threadedly connected through the center of the movable frame 24, one end of the threaded rod 25 is rotatably connected to the cooling table 1, and one end of the threaded rod 25 is fixedly connected to a knob 9 that is inserted through the cooling table 1. When the knob 9 is turned to drive the threaded rod 25 to rotate, the threaded connection between the threaded rod 25 and the movable frame 24 can enable the movable frame 24 to move on the outer surface of the threaded rod 25.

[0030] The effects achieved by this embodiment are as follows: in the prior art, the cooling device cannot evenly cool the bottom of the plastic pipe, which not only causes uneven cooling of the entire pipe, affecting the performance and quality of the pipe, such as causing problems such as uneven stress and different shrinkage rates of the pipe, but also if the lower end cannot be effectively cooled, the lower end of the pipe will be damaged due to excessive temperature, melting and deformation. Compared with the prior art, the pipe body 8 can be driven to rotate at the same time during the cooling process of the pipe body 8, which can not only ensure that all parts of the pipe body 8 are evenly sprayed with the coolant, avoiding the problem of local overheating or insufficient cooling, and reducing the stress concentration and cracking of the pipe body 8 due to temperature differences, thereby extending the service life of the pipe body 8, but also helps to distribute the coolant more evenly on the surface of the pipe body 8, thereby improving the performance and quality of the pipe body 8 after cooling;

[0031] By cooperating with the connecting rod 21 and the lifting plate 23, the distance between the auxiliary rollers 7 can be changed, so that the auxiliary rollers 7 can drive the pipe bodies 8 of different thicknesses to rotate during the cooling process. Not only can the cooling process be flexibly adjusted to meet the cooling requirements of pipe bodies 8 of different thicknesses, making the production process more flexible and changeable, but also all parts of the surface of different pipe bodies 8 can be evenly cooled, reducing stress concentration and deformation, thereby reducing the risk of cracks and damage to the pipe body 8.

[0032] The working process and principle involved in the overall content of the above embodiment are as follows:

[0033] When the staff needs to use the cooling table 1 to cool the pipe body 8, first turn the knob 9 according to the thickness of the pipe body 8 to drive the threaded rod 25 to rotate on the cooling table 1, and drive the moving frame 24 to move horizontally on the upper end surface of the cooling table 1 through the threaded connection between the threaded rod 25 and the moving frame 24. During the movement of the moving frame 24, the lower end of the jacking plate 23 can be driven to move horizontally synchronously, so that the jacking plate 23 can be converted between a horizontal state and a vertical state. As the state of the jacking plate 23 changes, the jacking plate 23 can drive the lifting block 20 to rise and fall synchronously in the vertical groove 11 through the cylinder 22 connected to one end away from the moving frame 24, and the cylinder 22 can move up and down synchronously with the lifting block 20. During the up and down movement of the cylinder 22, the connecting rod 21 connected by the rotation of the outer surface can push the rotating shaft 12 to move closer or farther from each other, thereby changing the distance between the auxiliary rollers 7 connected to the rotating shaft 12, so that the pipe body 8 can be placed between the two auxiliary rollers 7.

[0034] In the process of the lifting block 20 driving the cylinder 22 to lift and lower to change the distance between the auxiliary rollers 7, since one of the lifting blocks 20 is installed on the upper end surface of the support plate 19, it can drive the support plate 19 to move up and down synchronously, and change the height of the drive motor 16 installed on the upper end surface of the support plate 19. When the height of the drive motor 16 changes, the drive motor 16 drives the auxiliary pulley 18 to rise and fall synchronously through the drive shaft 17 connected to the output end, so that the auxiliary pulley 18 can change synchronously when the position of the main pulley 14 connected to the two rotating shafts 12 changes, so that the belt 15 set between the auxiliary pulley 18 and the outer surface of the main pulley 14 always maintains tension;

[0035] When the distance between the auxiliary rollers 7 is adjusted, the staff can use the carrying tool to carry the pipeline body 8 to between the two auxiliary rollers 7, and then spray the coolant in the water tank 2 from the top of the pipeline body 8 through the nozzle 6 through the water pipe 4 and the diversion pipe 5. While the coolant is spraying, turn on the drive motor 16, and drive the auxiliary pulley 18 to rotate through the drive shaft 17 connected to the output end. At this time, the auxiliary pulley 18 can drive the two main pulleys 14 to slide synchronously in the same direction through the belt 15 wrapped around the outer surface. During the rotation of the two main pulleys 14, the auxiliary rollers 7 can be driven to rotate synchronously through the rotating shaft 12 connected to the main pulley 14. Since the pipeline is placed between the auxiliary rollers 7, during the movement of the auxiliary rollers 7 in the same direction, the friction between the auxiliary rollers 7 and the pipeline body 8 can make the pipeline body 8 rotate synchronously with the auxiliary rollers 7, so that the coolant sprayed by the upper nozzle 6 can be evenly sprayed on the surface of the pipeline body 8.
