Description

Technical Field

[0001] This utility model relates to the field of extruder cooling technology, specifically a plastic extrusion cooling device for producing nose bridge strips for face masks. Background Technology

[0002] Plastic nose bridge strips are produced through extrusion. During the extrusion process, the material is first melted at high temperature and then extruded to obtain a high-temperature strip. This extruded strip must be cooled and hardened before being fed into a pelletizer for further processing. In the plastic production equipment, a water tank filled with cooling water cools and hardens the freshly extruded, high-temperature strip, resulting in a plastic with optimized strength, impact resistance, heat resistance, hardness, and aging resistance.

[0003] After the nose bridge strip is extruded, it is placed in a water-filled tank for cooling. The water, in prolonged contact with the heated nose bridge strip, will also heat up. Furthermore, the water inside the tank needs constant circulation—that is, a continuous flow of cool water—making traditional cooling methods quite wasteful. Therefore, we propose a plastic extrusion cooling device for producing nose bridge strips for face masks. Utility Model Content

[0004] This invention provides a plastic extrusion cooling device for producing nose bridge strips for face masks, which has the advantage of saving cooling water and solves the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A plastic extrusion cooling device for producing nose bridge strips for face masks is designed, including a cooling pipe and a strip groove. The top of the strip groove is detachably equipped with a sealing cap. The cooling pipe is set inside the strip groove. The top of the cooling pipe is provided with a strip-shaped opening that passes through both ends. Several nozzles are arranged along the length of the cooling pipe on its side. The spraying ends of the nozzles are all located inside the cooling pipe. Several nozzles are connected to a water supply device through connecting pipes. The water supply device delivers water to each nozzle at a certain pressure. The nozzles spray water into the cooling pipe.

[0006] Preferably, a certain distance is provided between the two ends of the cooling pipe and the strip groove.

[0007] Preferably, the bottom of the cooling pipe is provided with multiple supports, and the bottom of the supports can be detachably installed on the bottom of the strip groove.

[0008] Preferably, the bottom of the strip groove is provided with a support.

[0009] Preferably, at least one drain outlet is provided on one side of the bottom of the strip groove.

[0010] Preferably, both ends of the strip groove are provided with openings corresponding to the cooling pipes.

[0011] Preferably, one end of the strip groove is provided with a water collection trough, which is connected to the opening. At least one support frame is detachably installed inside the water collection trough. An elastic rubber sleeve is installed in the middle of the support frame. The middle of the rubber sleeve is provided with a hole for the nose bridge strip to pass through. The end of the water collection trough away from the strip groove is provided with an outlet.

[0012] Preferably, a guide wheel is provided at the end of the strip groove away from the water collection tank, and both ends of the guide wheel are rotatably connected to the strip groove, with the guide wheel located at the opening.

[0013] Preferably, the bottom of the cooling pipe is provided with multiple water flow holes.

[0014] Compared with existing technologies, this invention, when in use, involves holding the freshly extruded nose strip in one's hand. As the extruder continues to extrude, the operator holds one end of the nose strip and inserts it into the slot through the opening. The nose strip is then placed further into the slot. Because atomized water is present within the slot, the heat of the nose strip is completely dissipated as it moves from one end to the other, thus completely cooling it. Due to the limited internal space of the cooling pipe, the nozzle can spray atomized water into the cooling pipe, filling it completely and significantly reducing water consumption.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 5 This utility model provides a technical solution: a plastic extrusion cooling device for producing nose bridge strips for face masks. The device is installed at the outlet of a plastic extruder. Its main structure includes a strip-shaped groove 1, with a detachable sealing cover 13 on the top. Specifically, the sealing cover 13 is connected to the strip-shaped groove 1 via a locking mechanism, facilitating the installation and opening of the sealing cover 13. The bottom of the strip trough 1 is provided with a support 5. With the support of the support 5, the strip trough 1 is roughly at the same height as the discharge port of the plastic extruder. The main function of the strip trough 1 is to collect cooling water. At least one drain outlet 6 is provided on one side of the bottom of the strip trough 1. The drain outlet 6 diverts the water in the strip trough 1 to another place through a pipe.

[0024] like Figure 3 and Figure 4 As shown, the top of the cooling pipe 7 is provided with a strip-shaped opening 9 that runs through both ends. The strip-shaped opening 9 is wider than the nose strip, so that when the operator holds the free end of the nose strip, he can easily place the nose strip that has just been extruded into the cooling pipe 7 through the strip-shaped opening 9. like Figure 3 As shown, the cooling pipe 7 is installed inside the strip groove 1, as follows: Figure 3 As shown, the bottom of the cooling pipe 7 is provided with multiple supports 11. The bottom of the supports 11 is detachably mounted on the bottom of the strip groove 1. The supports 11 have a T-shaped structure and are connected to the bottom of the strip groove 1 by bolts. Several nozzles 12 are arranged along the length of the cooling pipe 7 on its side. The nozzles 12 can be located on one side or both sides of the cooling pipe 7. Specifically, mounting holes matching the nozzles 12 are provided on the side of the cooling pipe 7. The nozzles 12 are installed in the mounting holes, so that the spray ends of the nozzles 12 are all located inside the cooling pipe 7. Several nozzles 12 are connected to a water supply device through connecting pipes 10, such as... Figure 1 and Figure 2As shown, the water supply device is a high-pressure water pump, which introduces external water into each nozzle 12. That is, the water supply device delivers water to each nozzle 12 at a certain pressure, and the nozzle 12 sprays water into the cooling pipe 7. At this time, the cooling pipe 7 can be filled with water droplets or atomized water.

[0025] Specifically, both ends of the strip groove 1 are provided with openings 8 corresponding to the cooling pipes 7. In actual use, the nose strip that has just been extruded by the extruder is held in the hand. As the extruder gradually extrudes, the nose strip also elongates. The operator holds one end of the nose strip and enters it into the strip groove 1 through the opening 8, and then continues to place the nose strip into the strip opening 9. Since there is atomized water in the strip opening 9, the heat of the nose strip can be completely dissipated when it moves from one end of the strip opening 9 to the other end. After cooling, the nose strip can be connected to the winding machine for winding and storage. It should be emphasized that the bottom of the cooling pipe 7 is provided with multiple water flow holes (not shown in the figure). The water sprayed from the nozzle 12 will flow into the strip groove 1 through the water flow holes and finally be discharged from the drain outlet 6. The water sprayed from each nozzle 12 is cold water, so the nose bridge strip can be completely cooled after passing through the cooling pipe 7. At the same time, the internal space of the cooling pipe 7 is small, and the nozzle 12 can spray water into the cooling pipe 7 in the form of atomized water, without filling the cooling pipe 7 with water, thereby greatly reducing the amount of water used.

[0026] It should also be noted that since the nose bridge strip is not very wide, the width of the strip opening 9 is also very small. Therefore, most of the water sprayed from the nozzle 12 will be concentrated in the cooling pipe 7, but a small amount of water will still splash out from the strip opening 9. So after the nose bridge strip is placed, the sealing cover 13 is put on, and the water splashed out from the strip opening 9 can be sealed in the strip groove 1.

[0027] Furthermore, a certain distance is provided between the two ends of the cooling pipe 7 and the strip groove 1, so as to prevent the water flowing out from both ends of the cooling pipe 7 from flowing out of the opening 8.

[0028] Based on the above embodiments, it should be further explained that water should be avoided from adhering to the nose bridge strip exiting the cooling pipe 7. To remove moisture from the surface of the nose bridge strip, such as... Figure 1 As shown, a water collection trough 4 is provided at one end of the strip groove 1. The water collection trough 4 is connected to the opening 8. At least one support frame 2 is detachably installed inside the water collection trough 4. Specifically, slots are provided on both sides of the water collection trough 4. During installation, the two sides of the support frame 2 are inserted into the slots. There is a gap between the support frame 2 and the bottom of the water collection trough 4. An elastic rubber sleeve 14 is installed in the middle of the support frame 2. The rubber sleeve 14 has a hole in the middle for the nose bridge strip to pass through. When the nose bridge strip passes through the hole, the hole tightens on the nose bridge strip. As the nose bridge strip passes through the rubber sleeve 14, the water cup rubber sleeve 14 on the nose bridge strip is scraped off, and the water flows into the strip groove 1 through the water collection groove 4. like Figure 1 As shown, an outlet 3 is provided at the end of the water collection tank 4 away from the strip trough 1, and the water flows out from the outlet 3 through the nose strip in the water collection tank 4.

[0029] Based on the above embodiments, further improvements can be made by providing a guide wheel 15 at the end of the strip groove 1 away from the water collection tank 4. The surface of the guide wheel 15 has a groove for the nose bridge strip to pass through. Both ends of the guide wheel 15 are rotatably connected to the strip groove 1, and the guide wheel 15 is located at the opening 8. In actual use, a guide wheel 15 (not shown in the figure) can also be provided at the outlet 3 to support the nose bridge strip.

[0030] Based on the above embodiments, further improvements can be made, with the high-pressure water pump mounted on bracket 5. In actual use, to conserve water resources, water can be piped from drain outlet 6 into the water chiller, and then the inlet of the high-pressure water pump can be connected to the water chiller. Alternatively, a radiator can be installed on the pipe, including a finned radiator or an automatic cooling radiator. When using a finned radiator, a fan needs to be installed next to it to blow air. Therefore, after the water is cooled by the water chiller or radiator, it flows back into the high-pressure water pump, thus achieving circulation. It should be noted that both water chillers and radiators used for cooling are existing technologies.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
