Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a cooling device for plastic flooring substrate. Background Technology

[0002] Plastic flooring is a floor covering material made primarily from polymer compounds (mainly resins). It is typically made of materials such as polyvinyl chloride (PVC), and features a wide variety of patterns and colors, making it highly decorative and suitable for various personalized needs. However, the production process of plastic flooring requires cooling the base material.

[0003] Currently, water cooling is commonly used to cool plastic flooring substrates. However, this requires a large amount of cooling water, resulting in significant water waste. Furthermore, the substrates need to be dried after water cooling, which increases the cooling process and costs. Therefore, we propose a cooling device for plastic flooring substrates. Utility Model Content

[0004] The purpose of this invention is to provide a cooling device for plastic flooring substrates. This device can rapidly cool the plastic flooring substrates using air cooling, saving water resources and eliminating the need for subsequent drying processes. It improves cooling efficiency and reduces costs. This invention solves the problem that currently, water cooling is commonly used for cooling plastic flooring substrates, but this requires a large amount of cooling water, resulting in significant water waste. Additionally, the substrates need to be dried after water cooling, which increases the cooling process and costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for plastic flooring material, comprising a cooling box, the cooling box being vertically connected, a feeding hopper being fixedly installed on the lower surface of the cooling box, a lock-type feeding valve being fixedly installed on the lower surface of the feeding hopper, a plurality of inclined plates being fixedly installed at equal intervals from top to bottom on both sides of the inner wall of the cooling box, and the inclined plates on both sides of the inner wall of the cooling box being staggered, and an air inlet pipe being fixedly connected to one side of the outer surface of the cooling box near the lower surface, and a cold zone fan being fixedly installed inside the air inlet pipe.

[0006] Preferably, a feeding hopper is fixedly installed on the upper surface of the cooling box, and the plastic flooring material is fed into the cooling box from the feeding hopper.

[0007] Preferably, the upper surface of the inclined plate is uniformly provided with a number of ventilation holes. The cooling air inside the cooling box passes through the ventilation holes and comes into contact with the plastic floor material on the inclined plate, which increases the contact area between the material and the cooling air. This allows the cooling air to better remove the heat from the material and reduce its temperature.

[0008] Preferably, the angle between the inclined plate and the inner wall of the cooling box is 90° > a > 75°, so that the inclined plate maintains a certain inclination, so that the plastic flooring material can slide down the inclined plate.

[0009] Preferably, the upper and lower surfaces of the air inlet duct are provided with through-holes near the outer side of the cold zone fan. A filter frame is movably inserted into the through-hole, and a dust filter is fixedly installed inside the filter frame. The dust filter is located inside the air inlet duct. When outside cold air enters the cooling box from the air inlet duct, it passes through the dust filter to remove dust and other impurities from the air. When it is necessary to clean the dust filter, the filter frame can be pulled out directly from the through-hole by the limiting cross plate. After cleaning, the filter frame can be inserted back into the through-hole.

[0010] Preferably, a limiting cross plate is fixedly installed on the upper surface of the filter frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up a cooling box, a feeding hopper, an airlock feeding valve, inclined plates, a feeding pipe, and a cooling zone fan, achieves rapid cooling of the plastic flooring material through air cooling, saving water resources and eliminating the subsequent drying process. It improves cooling efficiency and reduces costs. The plastic flooring material is fed into the cooling box from the top and slides down along multiple inclined plates distributed from top to bottom inside the cooling box. At the same time, the cooling zone fan works to allow cold air from the outside to enter the cooling box and flow from bottom to top inside the cooling box, contacting the material and exchanging heat to remove the heat from the material. The cooled material falls into the feeding hopper and is discharged through the airlock feeding valve.

[0013] 2. This utility model improves the cooling efficiency of the plastic flooring substrate by setting vent holes. The cooling air inside the cooling box passes through the vent holes and comes into contact with the plastic flooring substrate on the inclined plate, increasing the contact area between the substrate and the cooling air. This allows the cooling air to better remove the heat from the substrate and reduce its temperature.

[0014] 3. This utility model, by setting a through-hole, a filter frame, a dust filter, and a limiting cross plate, achieves the function of filtering the cold air entering the cooling box, so as to prevent dust and impurities from entering the cooling box. At the same time, it facilitates the disassembly and cleaning of the dust filter. When the outside cold air enters the cooling box from the air inlet pipe, the dust filter removes dust and other impurities from the air. When the dust filter needs to be cleaned, the filter frame can be pulled out directly from the through-hole by using the limiting cross plate. After cleaning, the filter frame can be inserted back into the through-hole. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-4 As shown, this utility model proposes a cooling device for plastic flooring substrate, including a cooling box 3, which is vertically connected. A feeding hopper 4 is fixedly installed on the upper surface of the cooling box 3, through which the plastic flooring substrate is fed into the cooling box 3. A discharging hopper 2 is fixedly installed on the lower surface of the cooling box 3, and an airlock discharging valve 1 is fixedly installed on the lower surface of the discharging hopper 2. Several inclined plates 5 are fixedly installed at equal intervals from top to bottom on both sides of the inner wall of the cooling box 3. The angle between the inclined plates 5 and the inner wall of the cooling box 3 is 90° > a > 75°, so that the inclined plates 5 maintain a certain inclination to facilitate the plastic flooring substrate to slide down on the inclined plates 5. The inclined plates 5 on both sides of the inner wall of the cooling box 3 are staggered. Several ventilation holes 6 are evenly arranged on the upper surface of the inclined plate 5. The cooling air inside the cooling box 3 passes through the ventilation holes 6 and comes into contact with the plastic floor material on the inclined plate 5, which increases the contact area between the material and the cooling air. This allows the cooling air to better remove the heat from the material and reduce its temperature. If the inclined plate 5 is made of aluminum or copper, which have good thermal conductivity, the cooling air can remove the heat from the material through heat transfer between the inclined plate 5 and the material. An air inlet pipe 7 is fixedly connected to one side of the outer surface of the cooling box 3 near the lower surface. A cold zone fan 8 is fixedly installed inside the air inlet pipe 7. When the cold zone fan 8 works, the cooling air from the outside enters the cooling box 3 from the air inlet pipe 7.

[0023] In use, the plastic flooring material is fed into the cooling box 3 from the feeding hopper 4. The material slides down along multiple inclined plates 5 distributed from top to bottom inside the cooling box 3. At the same time, the cooling zone fan 8 works to allow cold air from the outside to enter the cooling box 3 and flow from bottom to top inside the cooling box 3. The air comes into contact with the material and exchanges heat, carrying away the heat from the material. The cooled material falls into the discharge hopper 2 and is discharged through the airlock discharge valve 1.

[0024] Example 2

[0025] like Figure 3 and Figure 4 As shown, the present invention proposes a cooling device for plastic flooring material. Compared with Embodiment 1, this embodiment further includes through-holes 10 located on the upper and lower surfaces of the air inlet pipe 7 near the outer side of the cold zone fan 8. A filter frame 11 is movably inserted into the through-hole 10. The filter frame 11 is open on both sides and has a U-shape when viewed from the side. The top and bottom of the filter frame 11 are located inside the two through-holes 10 respectively. A dust filter 12 is fixedly installed inside the filter frame 11 and is located inside the air inlet pipe 7. A limiting plate 9 is fixedly installed on the upper surface of the filter frame 11. The length and width of the limiting plate 9 are larger than the through-hole 10 to prevent the filter frame 11 inside the through-hole 10 from slipping off.

[0026] In this embodiment, when cold air from the outside enters the cooling box 3 through the air inlet pipe 7, dust and other impurities in the air are filtered out by the dust filter screen 12. When it is necessary to clean the dust filter screen 12, the filter screen frame 11 can be pulled out directly from the through-hole 10 by the limiting horizontal plate 9. After cleaning, the filter screen frame 11 can be inserted into the through-hole 10.

[0027] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
