[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figures 1 to 3As shown, a fabric coating device includes: a feed roller 2, a scraper 3 and a feed head 4, the scraper 3 is arranged on one side of the feed roller 2; the feed head 4 has a storage cavity 41, and a discharge channel 42 connected to the storage cavity 41 is provided at the bottom of the feed head 4, the discharge channel 42 is aligned between the scraper 3 and the feed roller 2, and the feed head 4 is provided with an elimination device 5 for eliminating bubbles in the storage cavity 41.

[0027] In the present application, by providing an elimination device 5, the bubbles in the storage chamber 41 can be effectively reduced, and can be eliminated before the paint enters the fabric, thereby avoiding bubbles remaining on the fabric during the coating process to form bulges or bubble marks, ensuring the flatness and beauty of the fabric appearance and improving product quality.

[0028] Specifically, the elimination device 5 includes a fixed frame 51, a screw 52, ​​a drive motor 53, a movable frame 54 and a defoaming component 55. The fixed frame 51 is fixed on the feed head 4, the screw 52 is rotatably connected to the fixed frame 51 and is arranged along the length direction of the feed head 4, the drive motor 53 is fixed on the fixed frame 51 and is transmission-connected to the screw 52 for driving the screw 52 to rotate, the movable frame 54 is threadedly connected to the screw 52, ​​and the screw 52 drives the movable frame 54 to move back and forth; the defoaming component 55 is fixed on the movable frame 54 and the lower end of the defoaming component 55 extends into the storage chamber 41, the lower end of the defoaming component 55 has an elimination head 551, and the elimination head 551 gradually becomes larger from top to bottom.

[0029] In the present application, the drive motor 53 drives the screw 52 to rotate. Since the screw 52 is threadedly connected to the movable frame 54, the movable frame 54 moves back and forth along the screw 52. The defoaming component 55 fixed to the movable frame 54 also moves accordingly, and the elimination head 551 at the lower end of the defoaming component 55 moves within the storage chamber 41. The design of the elimination head 551 gradually increasing in size from top to bottom can better contact and process bubbles at different positions in the storage chamber 41, eliminating bubbles through physical action and pushing them upward, thereby preventing bubbles from flowing out of the discharge channel 42.

[0030] By driving the motor 53 and related mechanical structures to achieve active movement of the defoaming component 55, bubbles in the storage chamber 41 can be eliminated more comprehensively and promptly. The special shape of the elimination head 551 can adapt to bubbles of different positions and sizes in the storage chamber 41, thereby improving the defoaming effect.

[0031] Specifically, the cross-section of the eliminating head 551 is triangular, the tip of the eliminating head 551 is facing upward, and the eliminating head 551 has a first inclined guide surface 5511 and a second inclined guide surface 5512. The first inclined guide surface 5511 and the second inclined guide surface 5512 are mirror-imaged and respectively face the two ends of the storage chamber 41 along the length direction.

[0032] The design of the first inclined guide surface 5511 and the second inclined guide surface 5512 can guide the bubbles to move toward the upper end of the storage chamber 41, so that all the bubbles move upward, thereby improving the defoaming effect.

[0033] Specifically, the width of the storage cavity 41 is greater than the width of the discharge channel 42 .

[0034] Specifically, a accommodating groove 421 is opened on the inner wall of the discharge channel 42 of the feed head 4, and a sealing block 43 is slidably arranged in the accommodating groove 421. A push rod motor 44 is fixed on the feed head 4. The output shaft of the push rod motor 44 is connected to the sealing block 43 and can drive the sealing block 43 to move. The sealing block 43 can seal or open the discharge channel 42.

[0035] By driving the sealing block 43 with the push rod motor 44 to seal or open the discharge channel 42, precise control of the discharge can be achieved, allowing the timing and amount of discharge to be flexibly adjusted according to actual needs. When discharge is not required, the sealing block 43 can reliably seal the discharge channel 42, effectively preventing accidental leakage of paint, reducing waste and pollution to the working environment.

[0036] Specifically, the feed head 4 has a heating plate 6 therein.

[0037] It can prevent the paint from solidifying or agglomerating in the feed head 4, ensure the normal coating work, and reduce malfunctions caused by poor paint condition.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
