Description

Technical Field

[0001] The utility model relates to the technical field of water cooling devices, in particular to a water cooling device for PP yarn production. Background Art

[0002] PP yarn, also known as polypropylene general strength yarn, is mainly used for various civilian webbings such as webbings and ropes, mobile phone straps, shoelaces and backpack straps. When producing PP yarn, the polypropylene particles are first melted and extruded into a film, and then cut and stretched into yarn. In this process, the PP film needs to be input into the cooling water for cooling, so a water cooling device is used, because water is soft, which helps to cool the PP yarn without deformation, and the cost is relatively low.

[0003] However, since the temperature of water rises rapidly during the cooling process, flowing water is often used for cooling, which not only causes a large waste of water resources, but also increases production costs. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a water cooling device for PP yarn production, which can realize the recycling of water resources, thereby avoiding the waste of water resources and achieving the effect of reducing production costs.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water cooling device for PP yarn production, comprising a shell, wherein guide rollers are rotatably connected to the inside of the shell, and conveying rollers rotatably connected to the inside of the shell are arranged between the guide rollers, a base is embedded and fixed at the bottom of the shell, and a first water chamber and a second water chamber that are connected to each other are respectively opened inside the base, a driving motor is arranged on the front of the shell, a first pulley is fixedly connected to the front of the driving motor, a second pulley is arranged on the outside of the first pulley, and a rotating shaft extending to the inside of the first water chamber is fixedly connected to the inside of the second pulley on the lower side, and a cam is fixedly connected to the outside of the rotating shaft, and a piston plate arranged in the first water chamber and adapted to the second water chamber is arranged on the lower side of the cam, and a return spring is fixedly connected to the lower side of the piston plate, and a driving shaft extending to the inside of the shell and fixedly connected to the conveying roller is fixedly connected to the inside of the second pulley on the upper side, and a transmission belt is arranged between the first pulley and the second pulley, and a cooling mechanism is arranged inside the shell.

[0006] Preferably, the left and right sides of the shell are respectively provided with openings adapted to the size of the PP film.

[0007] Preferably, semiconductor refrigerators communicating with the first water chamber are respectively arranged on the front side of the shell.

[0008] Preferably, a door is provided on the back side of the shell.

[0009] Preferably, water guide holes communicating with the first water cavity are respectively formed on the upper surface of the base.

[0010] Preferably, the cooling mechanism comprises a diverter plate fixedly connected to the inside of the shell, a diverter cavity is provided inside the diverter plate, and nozzles communicating with the diverter cavity are respectively provided on the lower surface of the diverter plate.

[0011] Preferably, flow guide pipes communicating with the flow diversion cavity and extending to the interior of the second water cavity are respectively inserted on both sides of the diversion plate.

[0012] The beneficial effects of the utility model are:

[0013] 1. When in use, first open the door, let the PP film to be cooled be introduced through the opening on the left side of the shell, and then pass through the guide roller and conveying roller arranged inside the shell in turn, and then lead out through the opening on the right side of the shell, then close the door and start the drive motor, the first pulley is driven by the drive motor to rotate, and the first pulley drives the second pulleys on the upper and lower sides to rotate through the transmission cooperation with the transmission belt. When the second pulley on the upper side rotates, it can drive the conveying roller to rotate through the driving shaft to provide power for the advancement of the PP film, and when the second pulley on the lower side rotates, it will drive the cam to rotate through the rotating shaft. When the cam rotates, it drives the piston plate to reciprocate up and down through the cooperation with the reset spring. When the piston plate moves downward, it extends into the second water chamber and squeezes the water inside the second water chamber, so that the water inside the second water chamber enters the diversion chamber through the guide pipe and is sprayed on the PP film passing through the shell through the nozzle, thereby cooling the PP film. At the same time, the sprayed water will enter the first water chamber through the water guide hole and flow back to the second water chamber when the piston plate moves up again to the inside of the first water chamber. In this process, the water can be cooled by the semiconductor refrigerator to achieve the recycling of water resources, and the water circulating through the guide pipe will exchange heat with the outside world, thereby improving the cooling effect of the water, so as to better cool the PP film.
