Description

Technical Field

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

[0002] After injection molding, plastic products typically require cooling to ensure shape stability and facilitate subsequent processing. Currently, the common cooling method involves using a conveyor belt to transport the freshly molded plastic products to a cooling zone, where natural or forced air cooling is employed to achieve temperature reduction.

[0003] However, after injection molding, plastic products may have a small amount of plastic debris, burrs, or other impurities remaining on their surface. These impurities can easily fall off and adhere to the conveyor belt during transport. With prolonged operation, these impurities gradually accumulate, affecting not only the cleanliness of the conveyor belt but also potentially causing secondary contamination of subsequently transported plastic products, or even scratching the product surface and affecting product quality. Furthermore, the scattered impurities falling inside the equipment are difficult to clean. 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 after injection molding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cooling device for injection-molded plastic products includes a housing with two round rods rotatably connected to it. A sprocket is fixedly connected to one end and the other end of each of the two round rods. Multiple sprockets mesh with a chain of a mesh belt. The housing has an opening with a drawer slidably connected to it. The drawer is located below the mesh belt and has a mesh plate fixedly connected to it. A brush is fixedly connected to one end and the other end of the mesh plate, and both brushes are in contact with the bottom of the mesh belt.

[0006] Preferably, a water pump and an air pump are fixedly connected to one end and the other end of the housing. A pipe and a second pipe assembly are fixedly connected to one end and the other end of the water pump, respectively. The pipe is fixedly connected through the housing, and the second pipe assembly is fixedly connected through the housing. Multiple second nozzles are fixedly connected to the second pipe assembly at equal intervals. A first pipe assembly is fixedly connected to one end of the air pump. The first pipe assembly is fixedly connected through the housing, and multiple first nozzles are fixedly connected to the first pipe assembly at equal intervals.

[0007] Preferably, a rubber pad is fixedly connected to the outer wall of the drawer, the rubber pad is in contact with the drawer body, and a handrail is fixedly connected to the drawer.

[0008] Preferably, the housing is rotatably connected to multiple rollers, all of which are in contact with the mesh belt.

[0009] Preferably, a motor is fixedly connected to the housing, and the output end of the motor is fixedly connected to a corresponding round rod.

[0010] Preferably, the box body has openings at both one end and the other end.

[0011] Preferably, a valve body is fixedly connected to one end of the housing.

[0012] The beneficial effects of this utility model are as follows: 1. Through the coordination of the set box body, round rod, sprocket, mesh belt, opening body, drawer, mesh plate, and brushes, plastic products are transported by a transmission method of sprocket and mesh belt. The drawer located below the mesh belt is slidably connected at the opening body of the box body. The drawer is equipped with a mesh plate and two brushes. During the process of conveying plastic products by the mesh belt and sprocket, the relative movement of the mesh belt and brushes allows the two brushes to sweep away plastic debris, burrs, and other debris attached to the mesh belt. The debris falls directly onto the mesh plate in the drawer for centralized collection. This not only effectively prevents the long-term accumulation of debris on the mesh belt, which affects its cleanliness and prevents secondary pollution or scratches on the surface of the plastic products being transported later, but also ensures the stability of product quality. Moreover, the sliding design of the drawer allows the operator to easily pull it out of the opening body of the box body and easily clean the debris collected on the mesh plate. This solves the problem of scattered debris falling into the equipment and being difficult to clean in traditional equipment, and significantly reduces the difficulty and workload of equipment maintenance. 2. Through the coordinated operation of an air pump, a first pipe assembly, a first nozzle, a pipe body, a water pump, a second pipe assembly, and a second nozzle, water is drawn from the bottom of the inner wall of the tank by the water pump through the pipe body. The second nozzle of the second pipe assembly then sprays water onto the plastic products conveyed by the mesh belt for cleaning and cooling. Finally, air is sprayed through the first pipe assembly and the first nozzle by the air pump to dry the products, forming a continuous process of cleaning followed by drying. This effectively removes residual stains and debris from the product surface through spraying and rapidly dries the products using airflow, preventing moisture residue from affecting subsequent processing. The integrated design also shortens the processing path, improves overall processing efficiency, and ensures the cleanliness and dryness of the plastic products, thus contributing to product quality stability.

[0015] 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.

[0016] Example 1, referring to Figures 1 to 5 A cooling device for injection-molded plastic products includes a housing 1. Two round rods 2 are rotatably connected to the housing 1. Each round rod 2 has a sprocket 3 fixedly connected to one end and the other end. Multiple sprockets 3 mesh with the chain of a mesh belt 4, forming a complete transmission mechanism. The mesh belt 4 can convey the plastic products. The housing 1 has an opening 5, and a drawer 6 is slidably connected to the opening 5. The inner wall of the opening 5 is machined with guide grooves to facilitate the sliding of the drawer 6, ensuring that the drawer 6 can move smoothly along a fixed trajectory after installation. The drawer 6 is located on the mesh belt 4. Below, to ensure that debris falling from the conveyor belt 4 can fall into the drawer 6, the drawer 6 is fixedly connected to a mesh plate 7. The mesh plate 7 can intercept plastic scraps, burrs and other debris, and can also allow water to pass through, thus separating the debris from the water. Brushes 8 are fixedly connected to one end and the other end of the mesh plate 7. When the conveyor belt 4 moves, the brush bristles can use the friction generated by the relative movement to sweep the debris attached to the surface of the conveyor belt 4 away from the conveying direction, ensuring that the debris can be smoothly removed from the conveyor belt 4 and fall onto the mesh plate 7. Both brushes 8 are in contact with the bottom of the conveyor belt 4.

[0017] In this embodiment, a water pump 13 and an air pump 9 are fixedly connected to one end and the other end of the housing 1. The models of the water pump 13 and the air pump 9 are selected according to actual working requirements. A pipe body 12 and a second pipe group 14 are fixedly connected to one end and the other end of the water pump 13, respectively. The pipe body 12 is fixedly connected through the housing 1, and the second pipe group 14 is fixedly connected through the housing 1. Multiple second nozzles 15 are fixedly connected at equal intervals to the second pipe group 14. The second nozzles 15 are used to spray water flow from top to bottom to clean and cool the products conveyed on the mesh belt 4. The water can also pass through the mesh belt 4 and fall back into the housing 1 for recycling. A first pipe group 10 is fixedly connected to one end of the air pump 9. The first pipe group 10 is fixedly connected through the housing 1. Multiple first nozzles 11 are fixedly connected at equal intervals to the first pipe group 10. The first nozzles 11 are used to spray airflow to dry the products. A rubber pad 19 is fixedly connected to the outer wall of the drawer 6. The rubber pad 19 is connected to the opening body 5. The rubber pad 19 has the same outer dimensions as the outer wall of the drawer 6. When the drawer 6 is fully pushed into the box 1, the rubber pad 19 can fit tightly against the inner wall of the opening 5. The drawer 6 is fixedly connected to the handle 20. The operator can easily pull out the drawer 6 by holding the handle 20 without directly contacting the drawer 6 body, which is both convenient and hygienic. The box 1 is rotatably connected to multiple rollers 17, all of which are in contact with the mesh belt 4 and can support the mesh belt 4 to ensure the stability of the mesh belt 4 in conveying the products. The box 1 is fixedly connected to the motor 21. The model of the motor 21 is selected according to the actual working requirements. The output end of the motor 21 is fixedly connected to the corresponding round rod 2. The box 1 has a box opening 16 at one end and the other end. The two ends of the length direction of the box 1, that is, the inlet end and the outlet end along the conveying direction of the mesh belt 4, are fixedly connected to a valve body 18 at one end of the box 1, which can discharge the wastewater in the box 1.

[0018] The working principle of this embodiment is as follows: In use, the motor 21, air pump 9, and water pump 13 are all connected to an external power supply and control device. The motor 21 drives the corresponding round rod 2 to rotate, which in turn drives the corresponding sprocket 3 to rotate, cooperating with the other sprockets 3 and rollers 17 to rotate the mesh belt 4. At the same time, the water pump 13 uses the pipe 12 to draw water from the bottom of the inner wall of the box 1, and sprays it out through the second pipe group 14 and the second nozzle 15. The air pump 9 delivers airflow to the first pipe group 10, and it flows out through the first nozzle 11. At this time, the mesh belt 4 is conveying... In the process of cleaning plastic products, two brushes 8, with the relative movement of the mesh belt 4 and the box 1 5 below the mesh belt 4, sweep plastic debris, burrs and other impurities attached to the mesh belt 4 onto the mesh plate 7 of the drawer 6 for collection. The operator can easily clean the debris by pulling out the drawer 6. At the same time, the water pump 13 sprays water to clean and cool the plastic products, and then the air pump 9 uses air to dry the cleaned products, forming a continuous process from debris cleaning, spray cleaning to air drying.
