Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable production technology, and in particular to a cooling device for plastic products. Background Technology
[0002] During the manufacturing and processing of cables, insulation coating is required. This is achieved by using a screw of a specific shape rotating within an insulated barrel, forcing plastic fed from a hopper forward. This process causes the plastic to melt uniformly and is then extruded through a die head and various shaped molds into continuous plastic layers of the desired shape, which are then wrapped around the cable core and exterior. During the insulation coating process, because the insulation layer is initially in a molten state, its surface temperature is high after it adheres to the circumference of the cable. Therefore, cooling treatment is necessary, typically using cooling water.
[0003] In the existing technology, circulating water is used to cool cables in order to save water. However, circulating water requires a chiller for cooling, which is not only bulky but also consumes a lot of energy during use, thus increasing production costs. Therefore, further improvement is needed. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cooling device for plastic products.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cooling device for plastic products, comprising a base plate, with support rods fixed at the four corners of the upper surface of the base plate, and a cooling water tank fixedly connected to the top of a plurality of support rods. A water storage tank is fixed on one side of the upper surface of the base plate, and an overflow pipe is fixedly connected between the top of the water storage tank and the cooling water tank. A diversion assembly is fixed on the other side of the upper surface of the base plate, and a pump body is fixed on the upper surface of the base plate. A pumping pipe is connected between the inlet of the pump body and the water storage tank, and a drain pipe is connected between the outlet of the pump body and the diversion assembly. A cooling assembly is fixed in the middle of the drain pipe. A return water pipe is fixedly connected between the diversion assembly and the cooling water tank. A temperature sensor is fixed on the inner wall of the cooling water tank, and a controller is installed on the outer wall of the cooling water tank.
[0006] Furthermore, the cooling water tank has an inlet and an outlet on both sides, and a first guide wheel is rotatably connected inside the cooling water tank near the inlet and outlet, and a second guide wheel is rotatably connected at both ends of the bottom of the cooling water tank.
[0007] Furthermore, the diversion assembly includes two vertical pipes, with several capillary tubes fixedly connected between the two vertical pipes. The bottom end of the vertical pipe near the pump body is connected to the drain pipe, and the top end of the vertical pipe near the return pipe is connected to the return pipe.
[0008] Furthermore, a fan is fixedly installed on the upper surface of the base plate and near several capillary tubes.
[0009] Furthermore, the cooling assembly includes a box fixed in the middle of the drain pipe, a thermoelectric cooler is fixed on the upper surface of the box, the cooling side of the thermoelectric cooler is attached to the upper surface of the box, and a plurality of fins are fixed on the cooling side of the thermoelectric cooler. The plurality of fins extend through the top wall of the box into the interior of the box, and a cooling fan is fixed on the heat dissipation side of the thermoelectric cooler.
[0010] Furthermore, both the semiconductor cooling chip and the temperature sensor are electrically connected to the controller.
[0011] The beneficial effects of this utility model are:
[0012] 1. In use, this utility model is a plastic product cooling device, which includes a cooling water tank, a water storage tank, an overflow pipe, a diversion component, a pump body, a return water pipe, and a fan. The pump body draws water from the water storage tank into the diversion component, and the fan cools the water flowing through the diversion component. The cooled water enters the cooling water tank through the return water pipe. The cable is cooled when it passes through the cooling water tank. Diverting the water increases the heat dissipation area, and the cooling effect of the fan can be guaranteed. Moreover, the energy consumption is lower, which is conducive to its widespread use.
[0013] 2. When in use, this utility model is a plastic product cooling device, which is equipped with a cooling component, a cooling water tank and a temperature sensor. The temperature sensor monitors the water temperature inside the cooling water tank in real time. When the temperature is lower than the preset value, the cooling component does not work. When the temperature is higher than the upper limit, the cooling component works. While ensuring the cooling effect, energy consumption is reduced as much as possible. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-4 As shown, a cooling device for plastic products is disclosed, comprising a base plate 1, with support rods 2 fixed at each of the four corners of the upper surface of the base plate 1. A cooling water tank 3 is fixedly connected to the top of the multiple support rods 2. A water storage tank 4 is fixed to one side of the upper surface of the base plate 1. An overflow pipe 5 is fixedly connected between the top of the water storage tank 4 and the cooling water tank 3. A diversion assembly 6 is fixed to the other side of the upper surface of the base plate 1. A pump body 7 is fixed to the upper surface of the base plate 1. A water inlet of the pump body 7 is connected to the water storage tank 4. A drain pipe 72 is connected between the outlet of the pump body 7 and the diversion assembly 6. A cooling assembly 8 is fixed in the middle of the drain pipe 72. A return water pipe 9 is fixedly connected between the diversion assembly 6 and the cooling water tank 3. A temperature sensor 11 is fixed to the inner wall of the cooling water tank 3, and a controller is installed on the outer wall of the cooling water tank 3.
[0023] The cooling water tank 3 has an inlet 31 and an outlet 32 on both sides. The inside of the cooling water tank 3 is rotatably connected to the inlet 31 and the outlet 32. The bottom ends of the cooling water tank 3 are rotatably connected to the second guide wheel 13.
[0024] In this embodiment, the height of the two first guide rollers 12 is the same as that of the inlet 31 and the outlet 32, and the height of the second guide roller 13 is lower than that of the first guide roller 12. After the cable enters the cooling water tank 3 from the inlet 31, it first passes over the top of the first guide roller 12 at the inlet 31, then passes under the two second guide rollers 13 in sequence, and finally passes over the first guide roller 12 at the outlet 32 and is pulled out from the outlet 32. This ensures that the water in the cooling water tank 3 can completely immerse the cable, guaranteeing that the cable can be completely cooled.
[0025] The diversion component 6 includes two vertical pipes 61, and several capillary tubes 62 are fixedly connected between the two vertical pipes 61. The bottom end of the vertical pipe 61 near the pump body 7 is connected to the drain pipe 72, and the top end of the vertical pipe 61 near the return water pipe 9 is connected to the return water pipe 9.
[0026] After the pump body 7 is started, the pump body 7 draws water out of the water storage tank 4. The water enters the nearest vertical pipe 61 along the drain pipe 72, and then flows through several capillary tubes 62, thereby increasing the heat dissipation area of the water. The water discharged from the capillary tubes 62 enters another vertical pipe 61 and then enters the cooling water tank 3 along the return water pipe 9. The water in the cooling water tank 3 returns to the water storage tank 4 through the overflow pipe 5, thus realizing water circulation.
[0027] A fan 10 is fixedly installed on the upper surface of the base plate 1 and near several capillary tubes 62.
[0028] When water passes through the inside of capillary tube 62, the fan 10 blows air onto capillary tube 62, thereby improving the heat dissipation effect of the water inside capillary tube 62.
[0029] The cooling assembly 8 includes a box 81 fixed in the middle of the drain pipe 72. A thermoelectric cooler 82 is fixed on the upper surface of the box 81. The cooling side of the thermoelectric cooler 82 is attached to the upper surface of the box 81, and a number of fins 83 are fixed on the cooling side of the thermoelectric cooler 82. The fins 83 extend through the top wall of the box 81 into the interior of the box 81. A cooling fan is fixed on the heat dissipation side of the thermoelectric cooler 82.
[0030] The semiconductor cooling chip 82 can cool the fins 83, and the fins 83 can then cool the water passing through the drain pipe 72 and inside the box 81, thus improving the cooling effect of the water. In addition, the cooling fan can ensure the heat dissipation effect of the semiconductor cooling chip 82 itself.
[0031] Both the thermoelectric cooler 82 and the temperature sensor 11 are electrically connected to the controller.
[0032] In this embodiment, the temperature sensor 11 is a DS18B20 (digital temperature sensor), the thermoelectric cooler 82 is a TEC1-12705 from the TEC1-127XX series, and the controller is a Siemens PLC controller, specifically an S7-1200 CPU 1214C. The temperature sensor 11 monitors the water temperature inside the cooling water tank 3 in real time. The controller has a temperature range setting. When the temperature sensor 11 detects that the water temperature inside the cooling water tank 3 is lower than the lower limit of the temperature range, the controller controls the thermoelectric cooler 82 to stop working; when the detected temperature is higher than the upper limit of the temperature range, the controller controls the thermoelectric cooler 82 to work, thereby cooling the circulating water and minimizing energy consumption.
[0033] Working principle: The cable enters the cooling water tank 3 through the inlet 31, passes through the first guide wheel 12 and the second guide wheel 13, and is pulled out through the outlet 32. The cable is cooled by the water in the cooling water tank 3. During this process, the pump body 7 works continuously. Driven by the pump body 7, water enters the diversion assembly 6 from the water storage tank 4 along the pump pipe 71 and the drain pipe 72, then enters the cooling water tank 3 through the return pipe 9, and finally returns to the cooling water tank 3 through the overflow pipe 5, thus realizing water circulation. During this period, the fan 10 works continuously, cooling the water flowing through the capillary tube 62. When the temperature sensor 11 detects that the water temperature in the cooling water tank 3 is higher than the upper limit of the temperature range, the controller controls the semiconductor cooling chip 82 to work, improving the cooling effect; when the temperature sensor 11 detects that the water temperature inside the cooling water tank 3 is lower than the lower limit of the temperature range, the controller controls the semiconductor cooling chip 82 to stop working.
