Description

Technical Field

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

[0002] Plastic products are made from plastics, which are resins (such as polyethylene, polypropylene, etc.) with additives added and then molded by heating. Common types of plastics include polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC).

[0003] Existing plastic products, such as plastic pipes, are all produced by extrusion. During operation, molten plastic raw material is placed in the extruder and then pushed and extruded by a screw conveyor shaft to form a tubular structure at the extrusion head. However, because the plastic pipe itself is relatively soft at high temperatures, it is easily bent and damaged due to its own weight as it is continuously conveyed. Therefore, it is necessary to cool the extruded plastic pipe to ensure proper forming. However, commonly used cooling equipment mainly consists of a water tank containing coolant. Although a circulation mechanism ensures the operating temperature of the coolant, this still requires the coolant in the tank to be pumped back into the cooling water tank. During this process, a certain temperature remains on the plastic pipe, preventing the coolant in the tank from reaching a lower temperature, significantly affecting the cooling effect on the plastic pipe. Therefore, we propose a processing cooling device for plastic products. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by providing a processing cooling device for plastic products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a processing and cooling device for plastic products, comprising a box with an opening at the top, the box being a long rectangular shell, an inlet pipe installed at the bottom of one end of the box, an outlet pipe installed at the bottom of the other end of the box, and slots opened at the top of both ends of the box. Multiple spaced first heat spreaders are installed on the bottom of the chamber, and a second heat spreader is connected to the bottom of the first heat spreaders. The second heat spreader is installed through the bottom of the chamber. A crossflow fan is provided on one side of the bottom of the housing. The air outlet of the crossflow fan corresponds to the side of the second heat exchange plate. The crossflow fan is mounted on a support frame, which is fixed to the bottom of the housing.

[0006] Preferably, a rectangular groove is provided at the bottom of the box body, and a bottom plate corresponding to the rectangular groove is provided at the bottom of the box body. A first heat dissipation plate is placed on the bottom plate and fixed vertically, and a second heat dissipation plate is provided through the bottom plate. A skirt is installed along the top edge of the bottom plate, the skirt corresponds to the side of the box body, and the skirt is detachably fixed to the box body.

[0007] Preferably, support legs are installed at the bottom corners of the base plate, and mounting holes are provided on the support legs.

[0008] Preferably, an arc-shaped groove is formed on the top of the first heat spreader.

[0009] Preferably, a through groove is provided at the bottom of the first heat spreader.

[0011] Preferably, an arc-shaped plate is connected to the bottom of the slot near the liquid inlet pipe, and a flange is installed at the other end of the arc-shaped plate.

[0012] The design scheme proposed in this utility model has the following beneficial effects in application: 1. This utility model, through the combined design of the first heat-spreading plate and the second heat-spreading plate, can quickly absorb heat from the coolant and force heat dissipation from the second heat-spreading plate through a cross-flow fan, ensuring that the coolant is always at a low temperature, thereby improving the cooling efficiency of plastic products.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example Reference Figures 1-4 A processing cooling device for plastic products includes a box 1 with an opening at the top. The box 1 is a long rectangular shell. An inlet pipe 16 is installed at the bottom of one end of the box 1, and a drain pipe 17 is installed at the bottom of the other end of the box 1. In actual use, a cooling water tank is also installed next to the box 1. The cooling water tank is filled with coolant, wherein the density of the coolant is greater than that of the plastic pipe. The cooling water tank is connected to the inlet pipe 16 and the drain pipe 17 through two conduits respectively, so that the coolant is introduced into the box 1 from the inlet pipe 16 and then discharged back into the cooling water tank from the drain pipe 17. A condenser is also installed on the cooling water tank to cool the returned coolant.

[0018] Slots 2 are provided at the top of both ends of the box 1. Support pads 3 are installed on the slots 2. The support pads 3 are high-temperature resistant rubber pads. If the plastic tube is affected, it will collide with the inner wall of the slot 2 and cause damage to the plastic tube.

[0019] An arc-shaped plate 4 is connected to the bottom of the slot 2 near the liquid inlet pipe 16, and a flange 5 is installed at the other end of the arc-shaped plate 4. In use, the housing 1 can be connected to the extrusion head of the extruder through the flange 5. After the plastic tube is extruded at the extrusion head, it can directly enter the housing 1 and come into contact with the coolant inside to start cooling.

[0020] Multiple spaced first heat spreaders 8 are installed on the bottom of the housing 1. A second heat spreader 11 is connected to the bottom of the first heat spreaders 8. The second heat spreader 11 is set through the bottom of the housing 1. As the coolant is sent into the housing 1, as the plastic tube comes into contact with the coolant, the coolant will absorb the heat on the plastic tube. The heat spreader, which is also in direct contact with the coolant, will absorb the heat in the coolant and transfer the heat to the outside of the housing 1. This ensures that the coolant in use will not affect the cooling effect on the plastic tube due to excessive temperature.

[0021] The bottom of the housing 1 has a rectangular groove 6, and a base plate 7 corresponding to the rectangular groove 6 is provided at the bottom of the housing 1. The first heat spreader 8 is placed on the base plate 7 and fixed vertically, and the second heat spreader 11 is provided through the base plate 7. A skirt 14 is installed along the top edge of the base plate 7. The skirt 14 corresponds to the side of the housing 1 and is detachably fixed to the housing 1. In actual use, the skirt 14 is fitted with the outer wall of the housing 1 with a clearance, and the skirt 14 is fixed to the housing 1 by bolts so that the heat spreader can be removed and cleaned on the housing 1. In order to ensure the sealing between the base plate 7 and the housing 1, a sealing gasket is provided between the base plate 7 and the housing 1, and the sealing gasket is fixed to the bottom of the housing 1.

[0022] It should be noted that an arc-shaped groove 9 is provided at the top of the first heat spreader 8 and a through groove 10 is provided at the bottom of the first heat spreader 8 to ensure the rapid transfer of coolant in the housing 1 and reduce the impact of the first heat spreader 8 on the flow of coolant.

[0023] After the heat is transferred to the second heat spreader 11, a crossflow fan 12 is provided on one side of the bottom of the housing 1. The air outlet of the crossflow fan 12 corresponds to the side of the second heat spreader 11, and the crossflow fan 12 is mounted on the support frame 13. The support frame 13 is fixed to the bottom of the housing 1. The crossflow fan 12 blows air onto the second heat spreader 11 to heat the second heat spreader 11, ensuring that the heat spreader can continuously cool the coolant in the housing 1.

[0024] When using the housing 1, support legs 15 are installed at the bottom corners of the base plate 7. Mounting holes are provided on the support legs 15, so that the support legs 15 can be placed on the support of the extruder, and then bolts can be taken and passed through the mounting holes to fix the support legs 15.

[0025] 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.
