Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a plastic strip cooling tank for plastic processing. Background Technology

[0002] Plastics are a class of synthetic polymer materials with plasticity. In plastic processing and production, plastic masterbatch and additives are melted and mixed in a twin-screw extruder and then extruded to form strips of plastic. The strips fall into the cooling water in a cooling tank, where the cooling water cools the plastic strips. They are then cut into uniform plastic granules by a pelletizer.

[0003] Currently, the cooling water in the cooling tank rises in temperature after absorbing heat from the plastic strips for a long time, which reduces the cooling effect on subsequent plastic strips. Furthermore, some cooling water adheres to the plastic strips when they leave the cooling water, affecting the subsequent cutting of the plastic strips by the pelletizer. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a cooling tank for plastic processing that can improve the cooling effect of the cooling tank on plastic strips and dry the cooled plastic strips.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cooling tank for plastic strips in plastic processing, comprising:

[0007] The water storage tank contains cooling water for cooling the plastic strips;

[0008] A heat exchange assembly is installed on one side of a water storage tank. The heat exchange assembly includes two fixed boxes and multiple heat exchange tubes. The two fixed boxes are arranged opposite each other, and each heat exchange tube is arranged between the two fixed boxes. The two ends of the heat exchange tubes are respectively connected to the two fixed boxes, and the two fixed boxes are respectively connected to the two ends of the water storage tank.

[0009] And a cooling fan, which is located below the heat exchange assembly so that air passes through the heat exchange assembly and the plastic strip in sequence.

[0010] Furthermore, the heat exchange tubes are made of copper.

[0011] Furthermore, the heat exchange tubes are evenly spaced.

[0012] Furthermore, one of the fixed boxes is provided with a water outlet pipe on one side, one end of which extends to one end of the interior of the water storage tank, and the other fixed box is provided with a connecting pipe on one side, one end of which connects to the other end of the interior of the water storage tank.

[0013] Furthermore, a water pump is installed on the water storage tank and is mounted on the connecting pipe. The water pump is used to transport the cooling water in the water storage tank to the heat exchange components.

[0014] Furthermore, a ventilation duct is provided on one side of the water storage tank, a cooling fan is located inside the ventilation duct, and a heat exchange component is located on the top of the ventilation duct.

[0015] Furthermore, a filter screen is installed at the bottom of the ventilation duct.

[0016] Furthermore, it also includes a rotating roller, which is located on the top side of the water storage tank. The rotating roller is supported on the bottom of the plastic strip, and the outside of the rotating roller is provided with an absorbent sponge.

[0017] Furthermore, a squeezing roller is rotatably connected to the water storage tank. The squeezing roller is located below the rotating roller and is in close contact with the rotating roller. A drive motor is provided on the water storage tank, and the output shaft of the drive motor is connected to the rotating roller.

[0018] Furthermore, the interior of the water storage tank is equipped with multiple support rollers at horizontal intervals, each of which is used to support the plastic strip.

[0019] The beneficial effects of this utility model are as follows:

[0020] In this invention, a cooling tank for plastic strips used in plastic processing cools the plastic strips with cooling water. A water pump delivers the used cooling water from the storage tank to the heat exchange components. The cooling water passes through multiple heat exchange tubes. As the cooling water passes through the heat exchange tubes, a cooling fan drives air through each heat exchange tube, thereby carrying away the heat from each heat exchange tube and cooling the cooling water. The cooled water returns to the storage tank to continue cooling the plastic strips. After the air carries away the heat from each heat exchange tube, the air temperature rises. The hot air passes through the plastic strips that have left the cooling water, thereby drying them and facilitating subsequent pelletizing of the dried plastic strips.

[0021] Furthermore, after the plastic strip leaves the cooling water, it will first slide over the rotating roller. The water-absorbing sponge on the outside of the rotating roller will absorb the residual cooling water on the outside of the plastic strip, which will facilitate the subsequent drying of the plastic strip and improve the drying effect.

[0031] Example 1

[0032] Reference Figure 1-4 A cooling tank for plastic strips used in plastic processing is applied to improve the processing effect of plastic strips and facilitate the drying of plastic strips after cooling with cooling water.

[0033] The plastic strip cooling tank for plastic processing includes a water storage tank 1, a heat exchange component 4, and a cooling fan 501;

[0034] The water storage tank 1 is equipped with cooling water for cooling the plastic strips 8. The plastic strips 8 can be extruded into strips by a twin-screw extruder, and then each plastic strip is immersed in the cooling water for cooling.

[0035] The heat exchange assembly 4 is located on one side of the water storage tank 1. The heat exchange assembly 4 includes two fixed boxes 401 and multiple heat exchange tubes 402. The two fixed boxes 401 are arranged opposite each other, and each heat exchange tube 402 is arranged between the two fixed boxes 401. Both ends of the heat exchange tube 402 are connected to the two fixed boxes 401 respectively. The heat exchange tubes 402 are copper tubes, and each heat exchange tube 402 is evenly spaced.

[0036] One of the fixed boxes 401 has a water outlet pipe 403 on one side, with one end of the water outlet pipe 403 extending into one end of the interior of the water storage tank 1. The other fixed box 401 has a connecting pipe 6 on one side, with one end of the connecting pipe 6 connected to the other end of the interior of the water storage tank 1. The water storage tank 1 is equipped with a water pump 7, which is mounted on the connecting pipe 6. The water pump 7 is used to transport the cooled water used in the water storage tank 1 to one of the fixed boxes 401 through the connecting pipe 6. After being cooled by multiple heat exchange pipes 402, the water enters the other fixed box 401 and finally returns to the water storage tank 1 through the water outlet pipe 403 to continue cooling the plastic strips that have entered the water storage tank 1.

[0037] A ventilation duct 5 is provided on one side of the water storage tank 1. A cooling fan 501 is installed inside the ventilation duct 5, and a heat exchange component 4 is installed on the top of the ventilation duct 5. This allows the cooling fan 501 to be located below the heat exchange component 4. Since the heat exchange component 4 is located below the plastic strip 8, the cooling fan 501 can drive the air, allowing the air to pass through the heat exchange component 4 and the plastic strip 8 in sequence. When the air passes through the heat exchange component 4, it will carry away the heat from each heat exchange tube 402. On the one hand, it cools down the cooling water inside the heat exchange tube 402, and on the other hand, it heats the air. This makes it easier for the hot air to dry the plastic strip 8 after it leaves the cooling water. A filter screen 502 is provided at the bottom of the ventilation duct 5. The filter screen 502 can filter the air and prevent dust from adhering to the plastic strip 8.

[0038] Multiple support rollers 101 are horizontally spaced inside the water storage tank 1. Each plastic strip 8 is arranged in parallel and moves inside the water storage tank 1, thereby cooling it with cooling water. Each support roller 101 can support the plastic strip 8 submerged in the cooling water.

[0039] Example 2

[0040] A cooling tank for plastic strips used in plastic processing further enhances the drying effect on plastic strips after they leave the cooling water by including a rotating roller 2. The rotating roller 2 is located on the top side of a water storage tank 1, and an absorbent sponge 201 is provided on the outside of the rotating roller 2. The rotating roller 2 is supported on the bottom of the plastic strip 8. After the plastic strip 8 leaves the cooling water, it slides over the rotating roller 2. The absorbent sponge 201 on the outside of the rotating roller 2 absorbs the residual cooling water on the outside of the plastic strip 8, thereby facilitating the subsequent drying of the plastic strip 8 and improving the drying effect of the plastic strip 8.

[0041] A squeezing roller 3 is rotatably connected to the water storage tank 1. The squeezing roller 3 is located below the rotating roller 2 and is in close contact with the rotating roller 2. A drive motor (not shown in the figure) is provided on the water storage tank 1. The output shaft of the drive motor is connected to the rotating roller 2. The drive motor can drive the rotating roller 2 to rotate. Since the squeezing roller 3 is in close contact with the rotating roller 2, it can squeeze the water-absorbing sponge 201 outside the rotating roller 2, squeezing out the cooling water absorbed by the water-absorbing sponge 201 and letting it fall into the water storage tank 1.

[0042] The working principle of the plastic strip cooling tank used for plastic processing is as follows: When in use, plastic strips 8 are extruded by a twin-screw extruder. Each plastic strip 8 is arranged in parallel and moved while immersed in the cooling water in the water storage tank 1, thereby cooling the plastic strips 8 by the cooling water.

[0043] After the plastic strip 8 is cooled and leaves the cooling water, it will slide over the rotating roller 2. The water-absorbing sponge 201 on the outside of the rotating roller 2 will absorb the residual cooling water on the outside of the plastic strip 8, which will facilitate the subsequent drying of the plastic strip 8 and improve the drying effect of the plastic strip 8. At this time, the squeezing roller 3 will squeeze the water-absorbing sponge 201 on the outside of the rotating roller 2, squeezing out the cooling water absorbed by the water-absorbing sponge 201 and letting it fall into the water storage tank 1, so that the water-absorbing sponge 201 can continuously absorb the residual cooling water of the plastic strip 8 after it is drained.

[0044] When cooling the plastic strip 8, the water pump delivers the used cooling water from the water storage tank 1 to a fixed box 401 through the connecting pipe 6. Then, the cooling water enters another fixed box 401 through multiple heat exchange pipes 402. When the cooling water passes through the heat exchange pipes 402, the cooling fan 501 can drive the air, so that the air passes through each heat exchange pipe 402, thereby taking away the heat from each heat exchange pipe 402 and cooling the cooling water. Then, the cooled water returns to the water storage tank 1 through the outlet pipe 403 to continue cooling the plastic strip entering the water storage tank 1.

[0045] When the cooling water passes through the heat exchange tube 402, it carries away the heat from each heat exchange tube 402 and heats the air passing through the heat exchange tube 402, so that the hot air can dry the plastic strip 8 that has left the cooling water when it passes through the plastic strip 8.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
