Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic product manufacturing technology, and in particular to a cooling rack for plastic product manufacturing. Background Technology
[0002] In the production process of plastic products, especially after the injection molding process, the products that have just been demolded usually have a high temperature (usually between 60°C and 150°C). In order to ensure the dimensional stability of the products, prevent them from deforming or warping due to internal stress, and allow them to enter the subsequent packaging, quality inspection or secondary processing stages as soon as possible, they must be cooled quickly and evenly.
[0003] In the production of plastic products, traditional cooling methods occupy a lot of production space and time. Moreover, uneven cooling can easily lead to defects such as internal stress and deformation in products, which seriously affect product quality. In order to improve efficiency, some companies have begun to adopt water cooling. However, existing water cooling devices are often simple in structure, and the water after rinsing flows everywhere, making the workshop environment wet, slippery and dirty. In addition, the direct discharge of wastewater also causes water waste and environmental pollution. Furthermore, water stains often remain on the surface of the cooled products, requiring an additional air drying process. The entire cooling process is separate, discontinuous, and has a low degree of automation, which seriously restricts the production efficiency and quality improvement of plastic products.
[0004] To address the above problems, a cooling rack for plastic product manufacturing needs to be designed to overcome them. Utility Model Content
[0005] The main objective of this invention is to provide a cooling rack for the production of plastic products, which can effectively solve the problems in the background art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A cooling rack for plastic product manufacturing includes a cooling rack with an open conveyor belt fixedly installed on its upper side. A rinsing box is fixedly installed at one end of the upper side of the cooling rack, and side plates are fixedly installed on both sides of the other end of the upper side of the cooling rack. Support frames are fixedly installed at equal intervals on the outer walls of the side plates. A connecting rod is rotatably connected to the upper side of the support frame via a bearing. A fan box is fixedly installed at one end of the connecting rod, and a regulating valve is fixedly connected to the other end of the connecting rod. Electric telescopic rods are fixedly installed on both sides of the side plates, and a guide plate is fixedly installed at one end of the electric telescopic rod. A water pipe is fixedly installed in the middle of the rinsing box.
[0007] As a preferred embodiment of this utility model, one end of the water pipe is fixedly connected to a curved water pipe, and a support plate is fixedly installed on the outer wall of the curved water pipe.
[0008] As a preferred embodiment of this utility model, high-pressure nozzles are arranged at equal intervals at the bottom of the curved water pipe, and a protective shell is fixedly installed on one side of the outer wall of the rinsing box.
[0009] As a preferred embodiment of this utility model, the water pipe passes through the middle of the protective shell, and a connecting plate is fixedly installed on one side of the outer wall of the rinsing box.
[0010] As a preferred embodiment of this utility model, a water pump is fixedly installed on the upper side of the connecting plate, and a water receiving tank is fixedly installed on one end of the upper side of the cooling rack.
[0011] As a preferred embodiment of this utility model, an electric push rod is fixedly installed at one end of the water receiving tank, and an inclined scraper is fixedly installed at one end of the electric push rod.
[0012] As a preferred embodiment of this utility model, a drain plate is fixedly installed at one end of the water receiving tank, and three sets of fan boxes are provided.
[0013] As a preferred embodiment of this utility model, the number of electric telescopic rods is two sets, and the number of guide plates is two sets. Beneficial effects
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, a cooling rack for plastic product production is designed, which integrates water cooling and air drying functions on the same conveyor line, forming a continuous operation process of "water washing-air drying". During the conveying process, the plastic products are successively sprayed with high-pressure water and dried by strong air. By utilizing the rapid cooling of water and the evaporation and heat absorption principle of air, the surface of the products is deeply and rapidly cooled, which greatly shortens the cooling cycle and improves the overall production efficiency.
[0015] 2. In this utility model, a cooling rack for plastic product production is designed. A water collection tank is set under the conveyor belt to collect wastewater after washing. An electric push rod drives an inclined scraper to push the sediment and liquid at the bottom of the tank to the drain plate for unified collection, filtration and recycling. This design not only avoids slippery conditions and sewage overflow in the production workshop, but also saves water resources and promotes environmentally friendly discharge, thereby reducing production costs.
[0016] 3. In this utility model, a cooling rack for plastic product production is designed. The fan box is rotatably connected to the support frame through connecting rods and bearings, and the angle is locked by adjusting valve. The operator can flexibly adjust the blowing angle of the fan box according to the shape, size and weight of different plastic products to ensure that the wind energy acts on the surface of the product most effectively, eliminate the dead corners of drying, thereby improving the drying and cooling effect and enhancing the versatility and adaptability of the equipment.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] like Figure 1-8 As shown, a cooling rack for plastic product manufacturing includes a cooling rack 1. An open-type conveyor belt 2 is fixedly installed on the upper side of the cooling rack 1. A rinsing box 7 is fixedly installed at one end of the upper side of the cooling rack 1. Side plates 15 are fixedly installed on both sides of the other end of the upper side of the cooling rack 1. Support frames 18 are fixedly installed at equal intervals on the outer wall of the side plates 15. A connecting rod 19 is rotatably connected to the upper side of the support frame 18 via a bearing. A fan box 20 is fixedly installed at one end of the connecting rod 19, and a regulating valve 21 is fixedly connected to the other end of the connecting rod 19. Electric telescopic rods 16 are fixedly installed on both sides of the side plates 15. A guide plate 17 is fixedly installed at one end of the electric telescopic rod 16. A water pipe 11 is fixedly installed in the middle of the rinsing box 7.
[0021] Please see the appendix Figure 1 Appendix Figure 2and attached Figure 3 As shown, one end of the water pipe 11 is fixedly connected to a curved water pipe 9, and a support plate 8 is fixedly installed on the outer wall of the curved water pipe 9. High-pressure nozzles 10 are arranged at equal intervals at the bottom of the curved water pipe 9. A protective shell 12 is fixedly installed on one side of the outer wall of the rinsing box 7, and the water pipe 11 passes through the middle of the protective shell 12. A connecting plate 13 is fixedly installed on one side of the outer wall of the rinsing box 7, and a water pump 14 is fixedly installed on the upper side of the connecting plate 13. A water receiving tank 3 is fixedly installed on one side of the upper end of the cooling rack 1. An electric push rod 4 is fixedly installed on one end of the water receiving tank 3. An inclined scraper 5 is fixedly installed on one end of the electric push rod 4. A drain plate 6 is fixedly installed on one end of the water receiving tank 3. The number of fan boxes 20 is three, the number of electric telescopic rods 16 is two, and the number of guide plates 17 is two. Among them, the cooling rack 1 is the main frame and support structure of the entire device, bearing all functional modules of conveying, rinsing and drying. Its structure must have sufficient strength, rigidity and stability to withstand the weight of the equipment, the weight of the conveyed products and the vibration generated during operation, to ensure the smooth operation of the entire cooling process. The main frame is preferably welded from rectangular carbon steel pipes to obtain good structural strength and cost-effectiveness. The surface can be powder coated or painted to enhance the corrosion resistance in humid environments. Among them, the perforated conveyor belt 2 is the core component for carrying and conveying plastic products. Its "perforation" design is crucial. It allows the rinsing water to penetrate the belt without obstruction and fall smoothly into the water receiving tank 3 below, realizing the immediate separation of water and material, which is the basis for subsequent water recycling. At the same time, the perforated structure also enhances the air circulation during air drying and improves the air drying efficiency. Considering the continuous rinsing of water and possible chemical cleaning agents, corrosion-resistant, high-strength and rust-resistant materials are selected, with stainless steel such as SUS304 or 316L being the first choice. They have a long service life and meet the hygiene requirements of food or medical grade plastic products. The water receiving tank 3 is located directly below the conveyor belt 2. It is a water collection container used to collect all the rinsing wastewater. Its design ensures that the production workshop is dry and clean, and prevents sewage from polluting the ground and the environment. It is a key prerequisite for realizing the recycling of water resources. Since it is in long-term contact with water, the material must be rust-proof and corrosion-proof. It is recommended to use stainless steel plates such as SUS304 welded together. The weld seam needs to be treated to prevent leakage. PPH or PVC engineering plastics can also be made by hot melt welding, which has better acid and alkali corrosion resistance. Among them, the electric push rod 4 is the power source that drives the tilting scraper 5 to reciprocate. It converts electrical energy into linear motion, providing stable and controllable power for the automatic drainage function of the tilting scraper 5, replacing manual operation and realizing the automation of the drainage process. The outer shell is usually made of aluminum alloy or carbon steel with powder coating, and the internal transmission mechanism is mostly made of steel. When selecting the model, the appropriate model should be selected according to the thrust and stroke. Its protection level should meet the requirements of use in humid environments. Under the drive of the electric push rod 4, the tilting scraper 5 reciprocates at the bottom of the water tank 3. Its tilting angle and reciprocating motion can effectively "scrape" the sediment and accumulated liquid at the bottom of the tank towards the drain plate 6, preventing impurities from accumulating and clogging at the bottom of the tank, and ensuring smooth and thorough drainage. Among them, the connecting rod 19 is the connecting part between the support frame 18 and the fan box 20. It passes through the bearing, enabling the fan box 20 to rotate 360 degrees around its axis. It is the core mechanical component for realizing the wind direction adjustment function.
[0022] The working process of this utility model is as follows: Using the cooling rack designed in this solution for plastic product production, during operation, the injection-molded plastic product is placed on the surface of the perforated conveyor belt 2 and conveyed into the washing tank 7. A water pump 14 draws cold water from an external cooling water tank into water pipe 11, which then enters a curved water pipe 9. High-pressure nozzles 10 spray the water onto the surface of the plastic product for washing. The washed liquid falls through the perforated conveyor belt 2 into the receiving tank 3. An external controller controls the extension and retraction of an electric push rod 4 to push... An inclined scraper 5 at one end pushes the liquid inside the water tank 3 toward the drain plate 6, facilitating its discharge. The washed plastic products continue to be conveyed by the perforated conveyor belt 2 and are air-dried and cooled by multiple fan boxes 20. The angle of the fan box 20 can be adjusted by adjusting the regulating valve 21. An external controller controls the extension and retraction of the electric telescopic rod 16 to move the guide plate 17 at one end, which can guide the conveyed plastic products and prevent them from deviating. The combination of water cooling and air cooling accelerates the cooling efficiency of the plastic product surface, thereby improving the cooling effect on the plastic products.
