Description

Technical Field

[0001] The utility model relates to the technical field of cooling structures, in particular to a cooling structure of a plastic foam product. Background Art

[0002] Plastic foam products are a kind of lightweight, heat-insulating and sound-absorbing material, which are often used in packaging, protection, insulation and filling. Foam products are usually hot-pressed using special molds, and need to be cooled after being taken out to achieve the shaping effect.

[0003] There are many ways to cool down plastic foam products in the prior art, including direct natural cooling, water cooling, coolant cooling and air cooling. For water cooling, when cooling plastics with water, since the foam floats on the water surface, a spray water cooling method is usually adopted. However, the spray method has a small contact area on the surface of the foam product, and some dead corners are difficult to spray. As a result, after cooling after a predetermined spraying time, a small part of the foam position is likely to not be fully formed. If the subsequent processing operation is carried out before it is fully formed, it is easy to cause deformation of the foam, resulting in a decrease in quality. Therefore, the utility model proposes a cooling structure for plastic foam products to solve the problems existing in the prior art. Utility Model Content

[0004] In view of the above problems, the utility model proposes a cooling structure for plastic foam products. The cooling structure for plastic foam products achieves effective cooling operation on the product through the cooperation of a pre-spraying mechanism, an impeller and an air cooling mechanism.

[0005] In order to solve the above-mentioned problems, the utility model proposes a cooling structure for plastic foam products, comprising a water pool, a pre-spraying mechanism is provided above the feed end of the water pool, an impeller is rotatably provided at the upper position in the water pool, a plurality of impellers are provided at intervals, a discharge conveyor belt is provided inside the discharge end of the water pool, an agitation mechanism is provided below the water pool, the agitation mechanism is located directly below the impeller, the agitation mechanism comprises a spray plate and a first nozzle, a nozzle is provided inside the spray plate, the first nozzle is arranged above the spray plate and connected with the nozzle, the output end of the first nozzle faces the impeller, a pump body is provided in the water pool, the output end of the pump body is connected with the nozzle inside the spray plate through a first water pipe, and an air cooling mechanism is provided on the water pool above the discharge conveyor belt.

[0007] A further improvement is that the blades of the impeller are arranged in an arc shape, and a through hole is provided on the surface of the impeller. There are multiple through holes evenly arranged. By arranging the blades of the impeller in an arc structure, the product can be lifted up to prevent it from slipping during the rotation of the impeller. At the same time, the through holes provided on the surface of the impeller can discharge the water on the blades from the through holes after the impeller blades rotate out of the water surface, so as to prevent it from leaking to the outside of the pool.

[0008] A further improvement is that a filter frame is provided inside the water pool, the pump body is arranged inside the filter frame, and the filter frame is composed of a combination of polytetrafluoroethylene filter plates. Through the provided filter frame, impurities generated in the water pool after long-term use can be filtered to prevent them from being discharged through the pump body again and causing blockage of the nozzle.

[0009] A further improvement is that the pre-spray mechanism comprises a first bracket and a second nozzle, the first bracket is arranged above the water pool, and the second nozzle is connected to the pump body through a second water pipe.

The set air cooling mechanism facilitates the final air cooling operation of the product that is about to be unloaded after the water is discharged. On the one hand, it can carry out the final cooling, and on the other hand, it can remove a large amount of water stains on the surface of the product.

[0011] Further improvements are: a limit bar is provided on the surface of the discharging conveyor belt, a plurality of limit bars are provided at intervals, the discharging conveyor belt is arranged at an angle, and the output end of the discharging conveyor belt extends above the output end of the water pool. Through the limit bars, the products above the discharging conveyor belt are limited to avoid slipping under water fluctuations and wind agitation.

[0012] The beneficial effects of the utility model are as follows: the cooling structure of the plastic foam product pre-cools the product through the pre-spraying mechanism, pre-cools and shapes the product to avoid damage to deformation in the following steps, and then passes through the impeller, and the product is pressed into the water for immersion through the rotation of the impeller.

[0021] Mounting plates 8 are symmetrically provided above the inner wall of the water pool 1, and both ends of the impeller 2 are rotatably connected to the two mounting plates 8. The end faces of adjacent impellers 2 are linked by belts. One end of an impeller 2 is driven by a motor 9. By driving the motor 9, an impeller 2 is driven to rotate, and then the impeller 2 linked with it is driven to rotate synchronously in the same direction.

[0022] The blades of the impeller 2 are arranged in an arc shape, and a through hole is arranged on the surface of the impeller 2. There are multiple through holes evenly arranged. By arranging the blades of the impeller 2 in an arc structure, the product can be lifted up to prevent it from slipping during the rotation of the impeller 2. At the same time, the through holes arranged on the surface of the impeller 2 can discharge the water on the blades from the through holes after the blades of the impeller 2 rotate out of the water surface, so as to prevent it from leaking to the outside of the pool 1.

[0023] A filter frame 10 is provided inside the water pool 1, and the pump body 6 is arranged inside the filter frame 10. The filter frame 10 is composed of a combination of polytetrafluoroethylene filter plates. The filter frame 10 can filter impurities generated in the water pool 1 after long-term use to prevent them from being discharged again through the pump body 6 and causing blockage of the nozzle.

[0024] The pre-spraying mechanism includes a first bracket 11 and a second nozzle 12. The first bracket 11 is arranged above the water pool 1. The second nozzle 12 is connected to the pump body 6 through a second water pipe 13. The pre-spraying mechanism is arranged to facilitate pre-cooling of the product and achieve basic shaping of the external surface. There are multiple second nozzles 12, and the spraying range is large, which is convenient for cooling a large area of ​​the product.

[0025] The air cooling mechanism includes a second bracket 14 and a third nozzle 15. The second bracket 14 is arranged above the water pool 1. A fan 16 is arranged outside the water pool 1. The third nozzle 15 is connected to the output end of the fan 16 through an air duct 17. The air cooling mechanism is arranged to facilitate the final air cooling operation of the product that is about to be discharged after the water is discharged. On the one hand, the final cooling is carried out, and on the other hand, a large amount of water stains on the surface of the product can be removed.

[0026] The surface of the discharging conveyor belt 3 is provided with a limiting strip 18, and a plurality of limiting strips 18 are provided at intervals. The discharging conveyor belt 3 is arranged obliquely, and the output end of the discharging conveyor belt 3 extends above the output end of the water pool 1. The limiting strips 18 are provided to limit the products above the discharging conveyor belt 3 to avoid sliding down under water fluctuations and wind agitation.

[0027] The cooling structure of the plastic foam product introduces the newly processed plastic foam product from the feed end of the water pool 1 into the water pool 1, and pre-sprays the product through a pre-spraying mechanism to pre-cool and shape the product to avoid damage and deformation in the following steps. The initially shaped product drives the water to move to the output end of the water pool 1 under the continuous rotation of the impeller 2, and then drives the product to move to the impeller 2. When the product is close to the impeller 2, the impeller 2 continues to rotate slowly counterclockwise, and the product close to the impeller 2 can be driven into the water below the impeller 2 and pressed into the water. The slow rotation of the impeller 2 can make the product stay in the water for a longer time. Due to the limitation of the adjacent blades of the impeller 2, the product will move with the rotation of the impeller 2. The product is brought to the position of the next impeller 2 by the previous impeller 2, and the plastic product will float up and approach the next impeller 2. The above steps are continued until it is moved out from the last impeller 2 and floats to the surface. In this process, the product is mostly underwater, and Because the impeller 2 drives it to flip, and cooperates with the pump body to supply water to the spray plate 4, the water is evenly sprayed from the first nozzle 5, which can achieve the continuous flipping and adjustment of the position of the foam product when it is underwater, so that the cooling water in the water pool 1 can contact the product in all directions without dead angles, so as to achieve a good cooling effect. There is no violence in the whole process mentioned above. The pre-spraying mechanism is not a high-pressure spray. The rotation speed of the impeller 2 is relatively low, usually one rotation per three seconds. At the same time, the speed of the impeller 2 can be appropriately adjusted according to the thickness and complexity of the plastic foam product to achieve the time when the product passes through the position of the impeller 2, thereby changing the time when the product is immersed in water to achieve a better cooling effect. After the cooling is completed, the product moves to the discharge end under the rotation of the impeller 2, and drives the product to move onto the discharge conveyor belt 3. The discharge conveyor belt 3 rotates to realize the unloading operation. Through the set air cooling mechanism, the product to be discharged can be air-cooled, and most of the water droplets can be blown off.
