Description

Technical Field

[0001] This utility model belongs to the field of resin-impregnated canvas softening technology, specifically relating to a resin-impregnated canvas softening treatment device. Background Technology

[0002] A PVC-coated canvas softening treatment device is a mechanical device used to soften PVC-coated canvas. Its working principle is mainly based on physical friction and chemical action to soften the PVC-coated canvas. By using the softening treatment device to soften the PVC-coated canvas, the bonding force between the PVC-coated canvas fibers can be adjusted, making the PVC-coated canvas softer overall, easier to fold, roll and transport. It also makes the PVC-coated canvas easier to process and cut, making it suitable for making various products that require softness and durability, such as tents, awnings, and sunshades, and better maintaining their shape and stability.

[0003] Chinese Patent Publication No. CN219410231U discloses a device for softening PVC-impregnated canvas, comprising a lower base, with support columns installed at the four corners of the lower end face of the lower base, and square grooves at the four corners of the upper end face of the lower base. A square block is installed inside each square groove, and an upper base is installed on the upper end face of each square block. A transverse groove is provided on one side of the outer surface of the lower and upper bases, with multiple high-pressure nozzles installed on one side of the inner surface of the transverse groove, and a strip-shaped groove on the other side of the inner surface of the transverse groove. A fan body is installed on the inner wall of the strip-shaped groove, and an electric heating plate is installed on one side of the two fan bodies facing each other. Two grooves are provided in the middle of the inner surface of the transverse groove, and two spray nozzles are installed on one side of the inner wall of each groove. This invention can simultaneously pat and soften the upper and lower surfaces of the PVC-impregnated canvas, improving the softening effect.

[0004] In practical use, this utility model typically requires wetting and softening the PVC-impregnated canvas before drying it. However, existing PVC-impregnated canvas softening devices generally employ simple drying structures, often relying on traditional hot air drying of a fixed position on the canvas. This results in a lengthy drying process, making it difficult to meet the demands of high-efficiency production. If the drying time is shortened to improve drying efficiency, the canvas is often not thoroughly dried, leaving a significant amount of moisture inside. This not only affects the softening effect of the canvas but may also lead to mold, deformation, and other defects during subsequent use, thus compromising the practicality and efficiency of the PVC-impregnated canvas softening device.

[0027] 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.

[0028] Example 1:

[0029] Please see Figure 1-5 This utility model provides a device for softening impregnated canvas, comprising:

[0030] Processing box 1 and cover 2;

[0031] A partition plate 3 is disposed inside the processing box 1. Multiple first guide rollers 4 are rotatably connected inside the processing box 1 located on one side of the partition plate 3, and multiple second guide rollers 5 are rotatably connected inside the processing box 1 located on the other side of the partition plate 3.

[0032] The dipped canvas body 6 is set inside the processing box 1. The dipped canvas body 6 passes through the partition plate 3. Both ends of the dipped canvas body 6 are respectively wrapped around the outside of multiple first guide rollers 4 and multiple second guide rollers 5, and all extend to the outside.

[0033] The drain pipe 7 is located on one side of the bottom of the treatment box 1. The dipped canvas body 6 on one side of the treatment box 1 is arranged in a "U" shape, and the dipped canvas body 6 on the other side of the treatment box 1 is arranged in a meandering shape.

[0034] Specifically, such as Figure 2 and Figure 4 As shown, two squeegee blades 8 are rotatably connected to one side of the treatment box 1. The two squeegee blades 8 abut against both sides of the dipped canvas body 6. Two positioning plates 9 are provided on one side of the treatment box 1. Two positioning grooves that are adapted to the positioning plates 9 are opened on both sides of the inner wall of the treatment box 1. The two ends of the two positioning plates 9 are located in the two positioning grooves on both sides and are slidably connected to the side wall of the positioning groove.

[0035] Through its design, the squeegees 8 on both sides of the dipped canvas body 6 can remove excess water from the dipped canvas body 6 after water comes out, thereby enabling the subsequent drying process of the dipped canvas body 6 to be completed more quickly.

[0036] Specifically, such as Figure 2 and Figure 4 As shown, each of the two positioning plates 9 has a contact plate 10 on one side. One end of each contact plate 10 is arc-shaped and rests against one side of each of the two wiper blades 8. The two contact plates 10 with arc-shaped ends can better push the two wiper blades 8 to rotate, so that the two wiper blades 8 can effectively remove excess water from the dipped canvas body 6.

[0037] Specifically, such as Figure 2 and Figure 5 As shown, both ends of the two positioning plates 9 are provided with limiting springs 11, and the other ends of the two limiting springs 11 on both sides are respectively set on one side of the two positioning grooves on both sides. The limiting springs 11 at both ends of the two positioning plates 9 can ensure that the two abutting plates 10 can always abut against one side of the two wiper blades 8, and that the two wiper blades 8 can always abut against the outside of the dipped canvas body 6, thereby ensuring the effect of removing water from the dipped canvas body 6.

[0038] Specifically, such as Figure 3 As shown, a U-shaped ventilation plate 12 is provided on one side of the treatment box 1. Multiple nozzles 13 are provided on both sides of the inner wall of the ventilation plate 12. The multiple nozzles 13 are located on both sides of the dipped canvas body 6. The multiple nozzles 13 located on both sides of the dipped canvas body 6 in a meandering arrangement can ensure the drying effect of the dipped canvas body 6. A heater 14 is provided on one side of the treatment box 1. The heater 14 is existing technology and will not be described in detail here. The air outlet of the heater 14 is connected to the ventilation plate 12.

[0039] Specifically, such as Figure 2 As shown, a ventilation pipe 15 is provided on one side of the treatment box 1. The ventilation pipe 15 can introduce the warm air sprayed from multiple nozzles 13 to the other side of the treatment box 1. The bottom end of the ventilation pipe 15 extends through the bottom of the partition plate 3 to the other side of the treatment box 1 and is arranged in a meandering shape. Multiple air outlets 16 are provided through the upper end of the ventilation pipe 15. The meandering ventilation pipe 15 can evenly introduce warm air to the other side of the treatment box 1. When the bubbles rise in the water, they will drive the surrounding water flow and form a local stirring effect, which helps to remove the dirt and impurities loosened and attached to the surface of the dipped canvas body 6, thereby improving the cleaning effect. An exhaust pipe 17 is provided on one side of the upper end of the treatment box 1.

[0040] See Figure 1-5When using the PVC-impregnated canvas softening treatment device to soften the PVC-impregnated canvas body 6, the PVC-impregnated canvas body 6 is first wrapped around the outside of multiple first guide rollers 4 and multiple second guide rollers 5. Then, softening liquid is added to one side of the treatment box 1. When the PVC-impregnated canvas body 6 moves inside the treatment box 1, it will pass through the softening liquid. When the PVC-impregnated canvas body 6 leaves the softening liquid, two squeegees 8 will remove excess water from the PVC-impregnated canvas body 6. The squeegeed PVC-impregnated canvas body 6 will enter the other side of the treatment box 1. When drying the PVC-impregnated canvas body 6, the heater 14 needs to be turned on. The air outlet of the heater 14 will introduce warm air into the ventilation plate 12, which will be evenly sprayed onto the PVC-impregnated canvas body 6 through multiple nozzles 13, thereby quickly and thoroughly drying the PVC-impregnated canvas body 6 and ensuring the softening effect of the PVC-impregnated canvas softening treatment device on the PVC-impregnated canvas body 6.
