Description

Technical Field

[0001] This utility model relates to the field of PVC board surface anti-oxidation technology, and more specifically, to a PVC floor surface anti-oxidation device. Background Technology

[0002] During the processing of PVC flooring, an anti-fouling coating is usually sprayed onto the surface of the flooring to protect it from dirt. Afterward, a protective gas is sprayed onto this coating to prevent it from oxidizing.

[0003] The existing protective gas is sprayed directly from the nozzle, resulting in a small contact time and area between the protective gas and the anti-fouling coating, and a poor anti-oxidation effect. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a PVC floor surface anti-oxidation device to solve the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An anti-oxidation device for PVC flooring surfaces, comprising:

[0007] Conveyor belts are used to carry and transport PVC sheets.

[0008] Sprayer; the sprayer applies an anti-fouling coating to the surface of PVC boards;

[0009] S-shaped air passage; the protective gas flows from one end of the S-shaped air passage to the other end, and the protective gas is located above the PVC board and diffuses into the PVC board.

[0010] Furthermore, it also includes a bracket installed on the conveyor belt, with multiple brackets, a rectangular box on the bracket, an opening on the lower surface of the rectangular box, and partitions on the inner wall of the rectangular box, with multiple partitions and the upper end of the partitions fixedly connected to the rectangular box.

[0011] One end of the partition has a notch, and the notch is located at one end of the partition. The notch on the adjacent partition is located at the other end of the partition. The PVC board moves close to the opening on the lower surface of the rectangular box.

[0012] The S-shaped airway forms a cavity between the rectangular box and the partition;

[0013] The width of the PVC board is equal to that of the rectangular box.

[0014] Furthermore, an annular box is provided on the side surface of the rectangular box, and an annular opening is opened at the lower end of the annular box, through which protective gas is discharged to form an air curtain.

[0015] Furthermore, the lower end of the annular box is constricted.

[0016] Furthermore, gas supply pipes are installed on both the annular and rectangular boxes.

[0017] The beneficial effects of this utility model are: the rectangular box allows the protective gas flow to diffuse along the S-shaped airway, which can effectively increase the contact time of the anti-fouling coating, extend the protection time, and improve the quality of the anti-fouling coating.

[0018] Through the action of the annular box, protective gas is discharged along the annular opening to form an air curtain, which can protect the anti-fouling layer in all directions. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] This application provides a device for preventing oxidation on the surface of PVC flooring. Please refer to [link / reference]. Figures 1-4 :include;

[0026] Conveyor belt 1 is used to carry and transport PVC board 2;

[0027] Sprayer 3; Sprayer 3 applies an anti-fouling coating to the surface of PVC board 2;

[0028] S-shaped air passage 4; the protective gas flows from one end of the S-shaped air passage 4 to the other end, and the protective gas is located above the PVC board 2 and diffuses into the PVC board 2.

[0029] In practical applications, the PVC board can be moved to the position of the sprayer 3 by the conveyor belt 1. The surface spraying operation (anti-fouling coating) is carried out by the sprayer 3. As the PVC board continues to move to the bottom of the S-shaped air channel 4, the S-shaped air channel 4 is connected to the external protective gas. The protective gas is blown onto the surface of the PVC board to prevent the freshly sprayed PVC board surface from oxidizing.

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 It also includes a bracket 11 provided on the conveyor belt 1. Multiple brackets 11 are provided. A rectangular box 5 is provided on the bracket 11. The lower surface of the rectangular box 5 is open. The inner wall of the rectangular box 5 is provided with a partition 6. Multiple partitions 6 are provided. The upper end of the partition 6 is fixedly connected to the rectangular box 5.

[0031] One end of the partition 6 has a notch 7, and the notch 7 is located at one end of the partition 6. The notch 7 on the adjacent partition 6 is located at the other end of the partition 6. The PVC board 2 moves close to the opening on the lower surface of the rectangular box 5.

[0032] The S-shaped airway 4 forms a cavity between the rectangular box 5 and the partition 6;

[0033] The width of PVC board 2 is equal to that of rectangular box 5.

[0034] In practical applications, the rectangular box 5 is kept in a stable state by the support 11. The partition 6 has a notch 7 at one end, and the notch 7 on the adjacent partition 6 is located at the other end of the partition 6. When the protective gas is input from one end of the rectangular box 5.

[0035] The protective gas moves from one end of the S-shaped air passage 4 to the other end; although there is a gap between the PVC board 2 and the rectangular box 5, the protective gas is continuously pushed into the S-shaped air passage 4 to maintain a certain air pressure.

[0036] The protective gas is then discharged from the gap between the PVC board 2 and the rectangular box 5;

[0037] By setting the width of PVC board 2 and rectangular box 5 to be equal, the gap between PVC board 2 and rectangular box 5 can be prevented from becoming larger; the gap between PVC board 2 and rectangular box 5 should be as small as possible so that the air pressure in S-shaped air passage 4 can be better maintained.

[0038] Reference Figure 1 , Figure 2 and Figure 3 An annular box 51 is provided on the side surface of the air curtain, and an annular opening 52 is opened at the lower end of the annular box 51. The protective gas is discharged along the annular opening 52 to form an air curtain.

[0039] In practical applications, the annular box 51 can blow air onto the PVC board 2 below it, which is then discharged from the annular opening 52. The airflow is in a vertically downward state, forming an air curtain that is perpendicular to the airflow direction of the gas discharged from the air curtain, thus minimizing contact between the air and the PVC board 2.

[0040] Reference Figure 3 The lower end of the annular box 51 is constricted 53.

[0041] In practical applications, the flow rate of the protective gas can be accelerated by setting the constricted 53.

[0042] Reference Figure 1 , Figure 2 and Figure 3 An air supply pipe 54 is installed on both the annular box 51 and the rectangular box 5.

[0043] In practical applications, the gas pipe 54 delivers high-pressure protective gas from the outside to the annular box 51 and the rectangular box 5.
