Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, and particularly relates to a plastic production cooling device. Background Technique

[0002] Plastic pipes refer to the general term for pipes made of plastic materials. Plastic pipes are light in weight. In the early production process, a variety of equipment will be used for processing, and the cooling device is also one of the various production steps. The plastic production cooling device is a device used to quickly reduce the temperature of plastic products after they are formed to ensure the quality and stability of the products. This device usually includes a cooling water tank, a cooling water circulation system, a heat exchanger, and a temperature control system. After the plastic products come out of the extruder, they enter the cooling device through a conveyor belt. The cooling water circulates through the pipeline and takes away the heat on the surface of the products. Effective cooling can prevent the products from deforming, warping or having other quality problems during the cooling process. The plastic production cooling device plays a key role in improving production efficiency and product quality and is applicable to the production lines of various plastic products.

[0003] The prior art (publication number: CN 217196863 U) discloses a circulating cooling device for plastic production, including a cooling box. At both ends of one side of the upper part of the cooling box, fixed blocks are fixedly arranged, and a first guide roller is rotatably arranged between the two fixed blocks. Inside the cooling box, a partition is vertically fixed at one end close to the first guide roller, and the partition divides the inside of the cooling box into two water storage areas. On the inner walls of the opposite sides of the cooling box at the upper edge position of the partition, a second guide roller is rotatably arranged. On the inner wall of one side of the cooling box close to the first guide roller, a rotating ring is rotatably arranged, and a rotating connection assembly is arranged between the rotating ring and the inner wall of one side of the cooling box. A plurality of water spraying pipes are rotatably arranged along one circle on the side of the rotating ring close to the partition.

[0004] Although the above patent realizes the pre-cooling of the extruded plastic through the cooperation of multiple water spraying pipes for repeated water spraying, and then guides it into the cooling box by a pressure roller for cooling after pre-cooling, avoiding the extruded plastic from directly entering the cooling box and adhering to impurities, there are the following disadvantages. The cooling water used for a long time will absorb a large amount of heat and the temperature will gradually rise, resulting in a poor cooling effect. It is necessary to regularly add cold water to cool down the cooling water. Due to the lack of a stirring process, the cold water may concentrate in certain areas, resulting in uneven cooling. The part of the plastic pipeline in contact with the cold water has a lower temperature, while other parts may be overheated, affecting the product quality. Therefore, further improvement is needed. For this reason, we propose a plastic production cooling device. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a plastic production cooling device, which can effectively solve the problems in the background technique.

[0006] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0007] A plastic production cooling device includes a water tank. A support plate is installed at the lower end of the water tank.

The driving component drives the injection component and the stirring blades to rotate, so that cold water is sprayed to different positions of the water tank and the water in the water tank is stirred.

[0008] Preferably, the injection component includes a water pipe. The water pipe is movably connected to the left inner wall of the water tank. A plurality of groups of nozzles distributed in a linear array are inserted through the outer surface of the water pipe. Each of the several groups of nozzles has several nozzles and is distributed in a circular array. The right end of the water pipe is movably inserted to the right side of the water tank.

[0009] Preferably, the driving component includes a motor. The motor is installed on the support plate. The output end of the motor is fixedly connected with a first gear.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. By setting the water injection component, the driving component and the stirring blade, the cold water can be evenly mixed with the water in the water tank. During use, the cold water is conveyed into the water pipe and then discharged through the nozzle, flowing into the water tank, so that the cold water is mixed with the water in the water tank, thereby reducing the temperature of the cooling water. At the same time, the control motor drives the first gear to rotate, and the first gear drives the water pipe to rotate through the second gear, so that the nozzle can spray the cold water to different positions of the water tank. At the same time, the water pipe drives the stirring blade to rotate, stirring the water in the water tank, so that the cold water can be fully mixed with the cooling water, quickly reducing the temperature of the cooling water, and improving the cooling efficiency and product quality;

[0016] 2. By setting the filtering component, the water entering the water pipe can be filtered. During use, the cold water enters the filtering box, and after being filtered by the filter screen, it then enters the water pipe, avoiding the surface of the plastic product being contaminated by impurities and also avoiding the inside of the nozzle being blocked by impurities.

[0025] As Figures 1-4 shown, a plastic production cooling device includes a water tank 1. Cooling water is provided inside the water tank 1. A support plate 10 is installed at the lower end of the water tank 1. A plurality of roller racks 2 distributed in a linear array are commonly installed between the front inner wall and the rear inner wall of the water tank 1. The roller racks 2 are used to support the movement of the plastic pipeline. An injection component 11 is provided inside the water tank 1. A plurality of stirring blades 12 are arranged on the outer surface of the injection component 11. The injection component 11 extends to the right side of the water tank 1. A driving component 7 is installed at the upper end of the support plate 10. The driving component 7 extends to the injection component 11. The driving component 7 drives the injection component 11 and the stirring blades 12 to rotate, so that cold water is sprayed to different positions of the water tank 1 and the water in the water tank 1 is stirred.

[0026] When the water in the water tank 1 gradually rises in temperature due to cooling the plastic pipeline, cold water is injected into the water tank 1 by setting the water injection component 11. At the same time, through the driving component 7 and the stirring blade 12, the cold water can be evenly mixed with the water in the water tank 1, quickly reducing the temperature of the cooling water and improving the cooling efficiency and product quality. The specific structure is as follows: The water injection component 11 includes a water pipe 111, and the water pipe 111 is movably connected to the left inner wall of the water tank 1. A number of groups of nozzles 112 distributed in a linear array are inserted on the outer surface of the water pipe 111. Each of the several groups of nozzles 112 has a number of nozzles and is distributed in a circular array. The right end of the water pipe 111 is movably inserted into the right side of the water tank 1. The driving component 7 includes a motor 71, and the motor 71 is installed on the support plate 10. The output end of the motor 71 is fixedly connected to a first gear 72, and the first gear 72 is meshed with a second gear 73. The second gear 73 is fixedly sleeved on the right part of the outer cylindrical surface of the water pipe 111. When in use, cold water is transported into the water pipe 111 by a water pump, and then discharged through a number of nozzles 112 and flows into the water tank 1, so that the cold water is mixed with the water in the water tank 1, thereby reducing the temperature of the cooling water. At the same time, the motor 71 is controlled to drive the first gear 72 to rotate. The first gear 72 drives the water pipe 111 and the nozzles 112 to rotate through the second gear 73, so that the nozzles 112 can spray the cold water to different positions of the water tank 1. At the same time, the water pipe 111 drives the stirring blade 12 to rotate, stirring the water in the water tank 1. A number of stirring blades 12 are fixedly connected to the water pipe 111, and the stirring blades 12 are located between adjacent two groups of nozzles 112. The stirring blades 12 are welded to the water pipe 111.

[0027] A rotary joint 9 is movably connected to the right end of the water pipe 111. The rotary joint 9 is installed on the set support plate 10. The rotary joint 9 is used to support the rotation of the water pipe 111, so that water can be transported into the rotating water pipe 111.

[0028] A filter box 81 is installed at the right end of the support plate 10. A filter screen 82 is arranged in the filter box 81. The filter box 81 is communicated with the rotary joint 9. The filter box 81 and the filter screen 82 cooperate together to filter the water entering the water pipe 111. When in use, the drainage end of the water pump is connected to the right side of the filter box 81. After the water enters the filter box 81, the filter screen 82 filters the cold water, and then enters the water pipe 111, avoiding the surface of the plastic product being contaminated by impurities and avoiding the inside of the nozzles 112 being blocked by impurities, ensuring the normal operation of the water injection component 11.

[0029] A box body 3 is installed at the right end of the water tank 1. Through holes 4 are opened at both the left and right ends of the water tank 1. A discharge hole 6 is opened at the right end of the box body 3. The through holes 4 and the discharge hole 6 are used to facilitate the movement of plastic products. Drain pipes 13 are inserted and connected to the rear ends of both the water tank 1 and the box body 3. The drain pipes 13 are used to discharge excess cooling water. During use, the just-extruded plastic product is sequentially passed through the two through holes 4, placed on the roller frame 2, cooled by the water in the water tank 1, and finally passed through the discharge hole 6 and connected to the traction device, so that the plastic product continuously moves.
