Description

Technical Field

[0001] This utility model relates to the field of fabric spraying technology, specifically to a seat fabric spraying device. Background Technology

[0002] To improve the tactile feel of seat fabrics, a PA coating is usually sprayed onto the fabric surface. This coating can significantly improve the fabric's hand feel, making it softer, and also provides windproof and drape properties, as well as enhancing the fabric's down-proof, color-fixing, and sand-fixing functions.

[0003] A prior art fabric spraying device, such as the utility model patent document with authorization announcement number "CN221132848U" and patent name "A fabric surface antibacterial agent spraying device", discloses a fabric spraying device including a support frame. The support frame is equipped with a spraying device and a drying device. The spraying device includes a first spraying pipe and a second spraying pipe, which are arranged from top to bottom on the support frame. The first spraying pipe and the second spraying pipe are respectively provided with a first spray nozzle and a second spray nozzle. The first spray nozzle is inclined downward and the second spray nozzle is inclined upward.

[0004] In the aforementioned patent documents, the fabric may have wrinkles during the spraying process. The raised parts of the fabric wrinkles will excessively absorb the paint, resulting in local accumulation, clumping, or dripping, forming thick wrinkles. For the concave areas, it is easy to cause missed spraying or an excessively thin coating, thereby reducing the fabric spraying effect. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a seat fabric spraying device. This device solves the technical problems mentioned in the background art, such as the possibility of wrinkles in the fabric during the spraying process. The raised parts of the wrinkles may excessively absorb paint, leading to local accumulation, clumping, or dripping, resulting in thick wrinkles. For the recessed areas, it can easily cause missed spraying or an excessively thin coating, thereby reducing the effectiveness of the fabric spraying.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A seat fabric spraying device includes a frame, on which two first fixed rollers are rotatably mounted, and on which a second fixed roller is rotatably mounted, the second fixed roller being located between the two first fixed rollers and parallel to each other. A first adjusting rod and a second adjusting rod for adjusting fabric tension are provided between one of the first fixed rollers and the second fixed roller. A drive assembly for synchronously driving the first adjusting rod and the second adjusting rod to move is provided on the frame. A spraying pipe for spraying the fabric surface is provided between another first fixed roller and the second fixed roller. A heating lamp for drying the sprayed fabric surface is provided on the frame.

[0008] Working principle:

[0009] First, the operator passes the fabric to be coated through the first fixed roller, the first adjusting roller, the second adjusting roller, the second fixed roller, and the first fixed roller in sequence. Then, the end of the fabric is fixed to the external fabric winding machine. The operator then drives the fabric to move by starting the external winding machine. When it is necessary to adjust the surface tension of the fabric, the operator can move the first and second adjusting rollers through the drive assembly to change the tension of the fabric. Subsequently, the spraying pipe on the frame can spray the fabric between the second fixed roller and the first fixed roller. After the fabric is coated, it passes through the heating lamp, which dries the coated surface of the fabric, causing the sprayed PA coating to solidify on the fabric surface. Finally, the coated fabric is wound up on the external winding machine.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] First, a first adjusting roller and a second adjusting roller are provided. The tension of the fabric can be adjusted by the first adjusting roller and the second adjusting roller, thereby reducing wrinkles on the fabric surface and facilitating the uniformity of the subsequent spraying of the fabric by the spraying pipe.

[0012] Second, a driving component is provided, through which the positions of the first adjusting roller and the second adjusting roller can be adjusted, thereby changing the tension of the fabric by changing the positions of the first adjusting roller and the second adjusting roller.

Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example:

[0018] like Figure 1 As shown, a seat fabric spraying device includes a frame 1, on which two first fixed rollers 2 are rotatably mounted, and a second fixed roller 3 is rotatably mounted. The second fixed roller 3 is located between the two first fixed rollers 2 and is parallel to the two first fixed rollers 2. A first adjusting rod 4 and a second adjusting rod 5 for adjusting the fabric tension are provided between one of the first fixed rollers 2 and the second fixed roller 3. The fabric passes sequentially over the two first fixed rollers 2, the first adjusting roller, the second adjusting roller, and the second fixed roller 3. The first adjusting roller and the second adjusting roller serve as tension fulcrums and work together with the first fixed rollers 2 and the second fixed roller 3 to guide the movement direction of the fabric and prevent the fabric from slack during transport.

[0019] like Figure 1 and Figure 2 As shown, both sides of the frame 1 are provided with sliding grooves 8. A first guide rod 9 is fixed in each of the two sliding grooves 8. A first slider 10 is slidably mounted on each of the two first guide rods 9. The two first sliders 10 are slidably mounted in the two sliding grooves 8 respectively. The two ends of the first adjusting rod 4 are rotatably mounted on the two first sliders 10 respectively. Two second guide rods 11 are fixed on the frame 1. A second slider 12 is slidably mounted on each of the two second guide rods 11 respectively. The two ends of the second adjusting rod 5 are slidably mounted on the two second sliders 12 respectively. The first slider 10 moves horizontally along the sliding groove 8, causing the first adjusting rod 4 to move horizontally, thereby forcing the second adjusting rod 5 to move synchronously through the guide groove 15 of the connecting block 14.

[0020] like Figure 1 and Figure 2As shown, the frame 1 is equipped with a drive assembly for synchronously driving the first adjusting rod 4 and the second adjusting rod 5 to move. The drive assembly includes two electric push rods 13 and two connecting blocks 14. The two electric push rods 13 are fixed on the frame 1 and their telescopic ends are respectively fixed to the two first sliders 10. The two connecting blocks 14 are fixed on the two first sliders 10. Each of the two connecting blocks 14 has a guide groove 15. The two ends of the second adjusting rod 5 slide through the two guide grooves 15 and rotate to abut against the guide grooves 15. The telescopic ends of the electric push rods 13 extend out and drive the first sliders 10 to move horizontally. The movement of the first sliders 10 drives the first adjusting roller to move. Thus, the guide grooves 15 of the connecting blocks 14 on the first sliders 10 guide the second adjusting roller to move directionally along the second guide rod 11, thereby synchronously adjusting the positions of the first adjusting roller and the second adjusting roller.

[0021] like Figure 1 and Figure 2 As shown, a spray pipe 6 for spraying the fabric surface is provided between another first fixed roller 2 and the second fixed roller 3. A material box 22 is provided outside the frame 1. The material in the material box 22 can be transported to the spray pipe 6 by a diaphragm pump 21. The spray pipe 6 is provided with several spray nozzles, so that the material in the spray pipe 6 can be sprayed onto the fabric surface through the spray nozzles. A heating lamp 7 is provided on the frame 1 for drying the fabric surface after spraying. After the fabric is sprayed, the heating lamp 7 can heat and cure the fabric, thereby drying the coating on the fabric surface and making it solidify quickly on the fabric surface.

[0022] like Figure 1 As shown, each of the two second guide rods 11 is fitted with a first spring 16. One end of each of the two second springs 20 is fixed to the frame 1, and the other end is fixed to the two second sliders 12. The first spring 16 is a compression spring, which can provide a pushing force to the second sliders 12.

[0023] like Figure 1 As shown, two fixed rods 17 are fixedly mounted on the frame 1, and fixed blocks 18 are slidably mounted on both fixed rods 17. A squeezing roller 19 is rotatably mounted between the two fixed blocks 18. The squeezing roller 19 is located above the second fixed roller 3 and abuts against the second fixed roller 3. A second spring 20 is sleeved on both fixed rods 17. One end of the two second springs 20 is fixedly mounted on the frame 1, and the other end is fixedly connected to the two fixed blocks 18. When the fabric passes through the second fixed roller 3, the squeezing roller 19 presses the fabric under the action of the second spring 20 to form a roller gap, thereby further improving the flatness of the fabric.

[0024] Working principle:

[0025] First, the operator passes the fabric to be sprayed sequentially through the first fixed roller 2, the first adjusting roller, the second adjusting roller, the second fixed roller 3, and the first fixed roller 2. Then, the end of the fabric is fixed to an external fabric winding machine. The operator then drives the fabric to move by starting the external winding machine. When it is necessary to adjust the fabric surface tension, the operator activates the electric push rod 13. The telescopic end of the electric push rod 13 extends, and the first slider 10 is pushed by the electric push rod 13. Therefore, the first slider 10 can move along the axial direction of the first guide rod 9 within the groove 8. This drives the first adjusting roller to move, which in turn moves the fabric towards the fabric feed end. Simultaneously, the connection on the first slider 10... Block 14 can drive the second slider 12 to move. The guide groove 15 on the connecting block 14 can force the second adjusting roller to move along the axial direction of the second guide rod 11, so that the first adjusting roller and the second adjusting roller can adjust the tension of the fabric. Then the tension-adjusted fabric passes between the second fixed roller 3 and the squeeze roller 19. The squeeze roller 19 squeezes the fabric surface under the action of the second spring 20, so that the fabric becomes flatter. Then the spraying pipe 6 on the frame 1 can spray the fabric between the second fixed roller 3 and the first fixed roller 2. The sprayed fabric passes through the heating lamp 7, which can dry the sprayed surface of the fabric, causing the sprayed PA coating to cure on the fabric surface. Then the sprayed fabric is wound up on the external winding machine.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
