[0032] In order to make the invention purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0034] The embodiment of the present invention provides a textile surface coating device, including a conveyor frame and a coating mechanism arranged on the conveyor frame, and the coating mechanism includes a feeding component, a distributing component, a scraping component and a rotating component. The feeding component includes a material box and a driving part for driving the material box to reciprocate, and a plurality of coating heads are arranged at intervals below the material box, and the material box is connected to the conveyor frame through the driving part; the distributing component is arranged at the rear end of the feeding component, and the distributing component includes a first rotating shaft and a plurality of distributing rings arranged equidistantly on the first rotating shaft, and the plurality of distributing rings are symmetrically distributed in two groups around the axis of the first rotating shaft; the scraping component is arranged at the rear end of the distributing component, and the scraping component includes a second rotating shaft and two groups of coating plates symmetrically arranged on the second rotating shaft; the rotating component is arranged on the conveyor frame, and is connected to the first rotating shaft and the second rotating shaft by transmission, and the rotating component realizes the continuous operation of distributing and scraping while completing the rotation of the two groups of distributing rings and the two groups of coating plates.

[0035] The driving unit drives the material box to move back and forth, so that the paint output by multiple coating heads to the textile forms a continuous S-shaped trajectory to cover the surface of the textile, and multiple equidistantly arranged distribution rings diffuse the paint on the S-shaped trajectory laterally. The paint is staggered and overlapped, so that the paint can be evenly spread on the surface of the textile to achieve preliminary uniformity. After that, the coating plate finally scrapes the paint flat, so that the paint can be evenly coated on the surface of the textile, effectively improving the uniformity of the coating; at the same time, the rotation component can drive the first rotating shaft and the second rotating shaft to rotate, so that the distribution ring and the coating plate can rotate, and when rotating, they can be seamlessly connected with the previous working trajectory, which can effectively avoid the accumulation of paint at the front end of the distribution ring and the coating plate, and further improve the uniformity of the coating.

[0036] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an embodiment of the present invention provides a textile surface coating device, including a conveyor frame 1 and a coating mechanism 2 arranged on the conveyor frame 1, and the coating mechanism 2 includes a feeding component 21, a distribution component 22, a scraping component 23 and a rotation component 24. The feeding component 21 includes a material box 211 and a driving part 213 for driving the material box 211 to reciprocate, and a plurality of coating heads 212 are arranged at intervals below the material box 211, and the material box 211 is connected to the conveyor frame 1 through the driving part 213; the distribution component 22 is arranged at the rear end of the feeding component 21, and the distribution component 22 includes a first rotating shaft 221 and a plurality of distribution rings 222 equidistantly arranged on the first rotating shaft 221, and the plurality of distribution rings 222 are symmetrically distributed in two groups around the axis of the first rotating shaft 221; The scraping component 23 is arranged at the rear end of the spreading component 22, and the scraping component 23 includes a second rotating shaft 231 and two groups of coating plates 232 symmetrically arranged on the second rotating shaft 231; the rotation component 24 is arranged on the conveying frame 1, and is transmission-connected with the first rotating shaft 221 and the second rotating shaft 231. The rotation component 24 drives the first rotating shaft 221 and the second rotating shaft 231 to rotate simultaneously, thereby realizing continuous operation of spreading and scraping, and completing the rotation of the two groups of spreading rings 222 and the two groups of coating plates 232 at the same time.

[0038] Specifically, the conveyor frame 1 is used to continuously convey textiles. The conveyor frame 1 inputs the textiles from the front end, and outputs and reels the textiles from the rear end after coating. A protective cover can be provided on the conveyor frame 1. The protective cover can cover the coating mechanism 2 inside, which can effectively prevent debris and dust in the outside air from falling on the surface of the textiles and then being covered by the coating during coating, thereby affecting the quality of the textiles.

[0039] like Figure 3 , Figure 4 As shown, the feeding assembly 21 includes a material box 211, a driving unit 213 and a coating head 212. The material box 211 is arranged above the textile and connected to the conveying frame 1 through the driving unit 213. The setting direction of the material box 211 is perpendicular to the conveying direction X of the textile. A plurality of coating heads 212 are arranged at intervals below the material box 211. The interior of the material box 211 is used to hold the paint. An air pump conveying component and a metering component can be arranged inside the material box 211 so that the paint can be continuously output from the coating head 212. The driving unit 213 can drive the material box 211 to reciprocate along the length direction. Thus, when the textile is continuously conveyed forward, the feeding assembly 21 can output the paint continuously and in an S-shaped track on the surface of the textile.

[0040] The distribution assembly 22 includes a first rotating shaft 221 and a plurality of distribution rings 222. The first rotating shaft 221 is longitudinally arranged above the textile, and both ends are connected to the conveying frame 1. The distribution ring 222 is in a circular ring shape at one end close to the textile, and there is a gap between the bottom of the distribution ring 222 and the surface of the textile, so that when the first rotating shaft 221 rotates, the distribution ring 222 will not contact the textile, so as to avoid the distribution ring 222 squeezing the textile. At the same time, the circular distribution ring 222 can also effectively reduce the accumulation of paint. The plurality of distribution rings 222 are divided into two groups, and each group of distribution rings 222 is equidistantly distributed along the length direction of the first rotating shaft 221 and fixedly connected to the first rotating shaft 221. The two groups of distribution rings 222 are symmetrically distributed around the axis of the first rotating shaft 221. When the textile is continuously conveyed, the plurality of distribution rings 222 can diffuse the paint of the S-shaped track laterally, so that the paint can be staggered and superimposed on the surface of the textile, so that the surface of the textile can be covered, and the initial uniformity of the paint is achieved.

[0041] The scraping assembly 23 includes a second rotating shaft 231 and two groups of coating plates 232. The second rotating shaft 231 is longitudinally arranged above the textile, and its two ends are connected to the conveying frame 1. There may be a gap between the bottom of the coating plate 232 and the textile. The coating plate 232 may be a strip plate structure with an arc-shaped cross section or a trapezoidal strip plate structure with an arc-shaped hypotenuse. The end surface of the coating plate 232 close to the apportionment assembly 22 is arc-shaped and smoothly transitions with the bottom, which is convenient for the paint to enter the bottom of the coating plate 232, can improve the scraping effect, and the paint is not easy to accumulate on the coating plate 232. The coating plate 232 is arranged along the length direction of the second rotating shaft 231, the length of the coating plate 232 is greater than or equal to the width of the textile, and the two groups of coating plates 232 are symmetrically arranged around the axis of the second rotating shaft 231. At the same time, a bearing plate 13 may be arranged below the textile, and the textile is placed on the bearing plate 13. When the coating plate 232 is coating the paint on the surface of the textile, the bearing plate 13 can support it to prevent the textile from being stretched due to its own ductility. While the textile is being continuously transported forward, the coating plate 232 can evenly coat the coating on the surface of the textile.

[0042] The rotation assembly 24 is arranged on the conveying frame 1 and is in transmission connection with the first rotating shaft 221 and the second rotating shaft 231. The first rotating shaft 221 and the second rotating shaft 231 are indirectly connected to the conveying frame 1 through the conversion assembly. The rotation assembly 24 can drive the first rotating shaft 221 and the second rotating shaft 231 to rotate simultaneously. The first rotating shaft 221 and the second rotating shaft 231 rotate 180°, so that the rotation of the two groups of apportionment rings 222 and the two groups of coating plates 232 can be realized. In the rotation process, the apportionment ring 222 and the coating plate 232 after the rotation can be connected to the working track of the apportionment ring 222 and the coating plate 232 before the rotation without interval, so that the apportionment ring 222 and the coating plate 232 can continuously and uninterruptedly disperse and flatten the paint. Thereby, the uniformity of the coating can be improved while effectively avoiding the accumulation of the paint.

[0043] like Figure 5 , Figure 6 As shown, in the embodiment of the present invention, the driving part 213 includes a connecting plate 2131, a fixed sleeve 2132, a movable shaft 2134 and a first motor 2136. The connecting plate 2131 is connected to one end of the material box 211 and is movably connected to the conveying frame 1; the fixed sleeve 2132 is connected to the other end of the material box 211; the movable shaft 2134 is arranged in the fixed sleeve 2132, and an annular and wavy sliding groove 2135 is provided on the outer wall of the movable shaft 2134, and a slider 2133 sliding in the sliding groove 2135 is provided inside the fixed sleeve 2132; the first motor 2136 is connected to the conveying frame 1, and the output shaft of the first motor 2136 is connected to the movable shaft 2134.

[0044] Specifically, the connecting plate 2131 is fixedly connected to one end of the material box 211, and a strip hole may be opened on the connecting plate 2131. A positioning column is fixedly provided on the conveying frame 1, and the positioning column is located in the strip hole; the fixed sleeve 2132 is fixedly connected to the other end of the material box 211, and the movable shaft 2134 is arranged in the fixed sleeve 2132. The movable shaft 2134 is cylindrical, and a wavy annular groove 2135 is opened on the outer wall of the movable shaft 2134. A slider 2133 sliding in the groove 2135 is arranged on the inner wall of the fixed sleeve 2132. When the first motor 2136 drives the movable shaft 2134 to rotate around the axis, the fixed sleeve 2132 can be driven to reciprocate along the axial direction of the movable shaft 2134 through the groove 2135 and the slider 2133, thereby driving the material box 211 to reciprocate.

[0045] like Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, in the embodiment of the present invention, the first rotating shaft 221 is connected to the second rotating shaft 231 through a transmission belt 241 , and the rotation assembly 24 includes a mounting cover 242 , a gear 243 , a rack 244 , a cylinder 245 and a reset portion 246 . The mounting cover 242 is slidably connected to the conveying frame 1, and the ends of the first rotating shaft 221 and the second rotating shaft 231 both pass through the mounting cover 242 and are located inside the mounting cover 242; the gear 243 is movably sleeved on the first rotating shaft 221; the rack 244 is fixedly connected to the conveying frame 1 and meshes with the gear 243; the fixed end of the cylinder 245 is fixedly connected to the conveying frame 1, and the telescopic end is connected to the mounting cover 242; the reset part 246 is arranged between the gear 243 and the first rotating shaft 221; wherein, when the cylinder 245 drives the mounting cover 242 to move away from the material box 211, the first rotating shaft 221 and the second rotating shaft 231 are driven to rotate through the gear 243 to realize the rotation of the sharing ring 222 and the coating plate 232, and when the cylinder 245 contracts, the reset part 246 is used to disengage the gear 243 from the first rotating shaft 221.

[0046] Specifically, an installation groove can be fixed on the conveying rack 1. The installation cover 242 is slidably arranged in the installation groove, and the installation covers 242 are arranged on both sides of the conveying rack 1. Both ends of the first rotating shaft 221 and the second rotating shaft 231 penetrate through the installation cover 242 and are inside the installation cover 242. The gear 243 is movably sleeved on one end of the first gear 243. The rack 244 is fixedly connected to the conveying rack 1. The gear 243 meshes with the rack 244. When the air cylinder 245 expands and contracts, it drives the installation cover 242 to reciprocate along the direction of textile conveying. The installation cover 242 covers the gear 243, the rack 244, etc. inside, which can play a protective role. When the air cylinder 245 drives the installation cover 242 to move away from the material box 211, it can drive the gear 243 to move and mesh with the rack 244, thereby driving the gear 243 to rotate, and then driving the first rotating shaft 221 and the second rotating shaft 231 to rotate; when the air cylinder 245 contracts, the reset part 246 can disconnect the gear 243 from the transmission connection with the first rotating shaft 221, so that the first rotating shaft 221 and the second rotating shaft 231 will not be driven to rotate, and the rotated sharing ring 222 and the coating plate 232 will not be reset.

[0047] For example, in the normal coating state, the installation cover 242 does not move, the distance between the installation cover 242 and the material box 211 is at the minimum value and will not change; when the sharing ring 222 and the coating plate 232 need to be rotated, the air cylinder 245 is started to push the installation cover 242 to move away from the material box 211. When the installation cover 242 moves, the gear 243 meshes with the rack 244, and the gear 243 rotates, then drives the first rotating shaft 221 to rotate, and further drives the second rotating shaft 231 to rotate simultaneously through the transmission belt 241. When the first rotating shaft 221 and the second rotating shaft 231 rotate, the sharing ring 222 and the coating plate 232 are rotated. After the gear 243 rotates 180°, the sharing ring 222 and the coating plate 232 complete the rotation; after the sharing ring 222 and the coating plate 232 complete the rotation, the air cylinder 245 drives the installation cover 242 to reset for the next rotation. Before the air cylinder 245 contracts, the reset part 246 can disconnect the gear 243 from the transmission connection with the first rotating shaft 221. Thus, when the air cylinder 245 contracts, the gear 243 will not drive the first rotating shaft 221 to rotate, and further, the rotated sharing ring 222 and the coating plate 232 will not be reset.

[0048] It can be understood that the sliding speed of the cylinder 245 pushing the mounting cover 242 is greater than the conveying speed of the textile. Thus, after the sharing ring 222 and the coating plate 232 complete the rotation, the starting point of the sharing ring 222 and the coating plate 232 after rotation to start working is located after the end point of the sharing ring 222 and the coating plate 232 before rotation. Therefore, the sharing ring 222 and the coating plate 232 after rotation can be seamlessly connected to the working track of the sharing ring 222 and the coating plate 232 before rotation, enabling the sharing ring 222 and the coating plate 232 to continuously and uninterruptedly disperse and scrape the coating, which is beneficial to improving the uniformity of coating.

[0049] As Figure 9 , Figure 10 and Figure 11 shown, further, a limiting groove 247 is formed on the conveying frame 1, and the reset portion 246 includes a bushing 2461, a limiting block 2464 and a reset ejector rod 2466. The bushing 2461 is fixedly sleeved on the first rotating shaft 221. A driving tooth 2462 is arranged on one side of the outer peripheral surface of the bushing 2461. The gear 243 is sleeved on the bushing 2461, and a driven tooth 2463 is arranged on the inner ring of the gear 243. The driving tooth 2462 meshes with the driven tooth 2463. The limiting block 2464 is slidably arranged in the limiting groove 247. The ends of the first rotating shaft 221 and the second rotating shaft 231 are both rotatably connected to the limiting block 2464. The reset ejector rod 2466 is fixedly connected to the limiting block 2464. When the cylinder 245 contracts, the reset ejector rod 2466 pushes the gear 243 to disengage the driving tooth 2462 from the driven tooth 2463.

[0050] Specifically, a limiting groove 247 is formed in the conveying rack 1 along the telescopic direction of the air cylinder 245. The limiting block 2464 slides in the limiting groove 247. The ends of the first rotating shaft 221 and the second rotating shaft 231 are both rotatably connected to the limiting block 2464. The air cylinder 245 can also be arranged in the limiting groove 247 or fixed on the conveying rack 1. The telescopic end of the air cylinder 245 is fixedly connected to the limiting block 2464. The air cylinder 245 can push the limiting block 2464 to slide back and forth and drive the gear 243 to rotate. A sleeve 2461 is sleeved on the first rotating shaft 221 and fixedly connected to the first rotating shaft 221. A driving tooth 2462 is arranged on one side of the outer peripheral surface of the sleeve 2461 close to the limiting block 2464, and the other side is a circumferential surface. The gear 243 is sleeved on the sleeve 2461, and a driven tooth 2463 is arranged on the inner ring of the gear 243. The driving tooth 2462 meshes with the driven tooth 2463. When the gear 243 rotates, it can drive the sleeve 2461 to rotate together, and then drive the first rotating shaft 221 to rotate. The reset ejector rod 2466 is connected to the limiting block 2464. The reset ejector rod 2466 can be an electric push rod. After the sharing ring 222 and the coating plate 232 complete the rotation, the reset ejector rod 2466 is activated and pushes the gear 243 in a direction away from the limiting block 2464, so that the driving tooth 2462 is disengaged from the driven tooth 2463. At this time, the gear 243 is sleeved on the side of the outer peripheral surface of the sleeve 2461 that is the circumferential surface. At this time, when the gear 243 rotates, it will rotate idly relative to the sleeve 2461 and will not drive the sleeve 2461 and the first rotating shaft 221 to rotate. Therefore, when the air cylinder 245 contracts, the gear 243 will not drive the first rotating shaft 221 to rotate, and then the rotated sharing ring 222 and the coating plate 232 will not be reset.

[0051] As Figure 10 , Figure 11 shown, furthermore, the reset portion 246 further includes a contact switch 2465 and an electromagnet 2467. The contact switch 2465 is electrically connected to the reset ejector rod 2466. Contact switches 2465 are arranged on both side walls of the limiting block 2464 along the sliding direction, and contacts corresponding to the contact switches 2465 are arranged on both side walls of the limiting groove 247. The electromagnet 2467 is arranged at the end of the reset ejector rod 2466. When the contact switch 2465 is connected, the electromagnet 2467 is energized. Among them, a slot 2431 is formed in the gear 243, and a magnetic block is arranged at the bottom of the slot 2431. When the air cylinder 245 does not expand or contract, the contact switch 2465 is connected, the reset ejector rod 2466 extends and is inserted into the slot 2431, and when the contact switch 2465 is disconnected, the reset ejector rod 2466 contracts.

[0052] It should be noted that before and after the rotation of the sharing ring 222 and the coating plate 232 starts and is completed, the two side walls of the limiting block 2464 are respectively in contact with the side walls of the limiting groove 247. The slot 2431 is located on the side of the gear 243 facing the limiting block 2464, and in the normal coating state, a slot 2431 is provided at the position on the gear 243 corresponding to the reset ejector rod 2466.

[0053] For example, in the normal coating state, the air cylinder 245 does not expand or contract. The contact switch 2465 on the limiting block 2464 close to the material box 211 is in contact with and connected to the contact on the side wall of the limiting groove 247. At this time, the reset ejector rod 2466 extends and is inserted into the slot 2431. The electromagnet 2467 at the end of the reset ejector rod 2466 is energized and attracts the magnetic block at the bottom of the slot 2431, so that the driving gear 2462 and the driven gear 2463 will not disengage from the meshing; when the air cylinder 245 starts to expand or contract, the contact switch 2465 is disconnected, the electromagnet 2467 is de-energized, the reset ejector rod 2466 contracts, and when the limiting block 2464 moves away from the material box 211, the gear 243 drives the first rotating shaft 221 to rotate; when the gear 243 rotates 180°, the sharing ring 222 and the coating plate 232 complete the rotation, and the contact switch 2465 on the side of the limiting block 2464 away from the material box 211 is in contact with the contact on the side wall of the limiting groove 247, the contact switch 2465 is connected, the reset ejector rod 2466 extends, so as to push the gear 243 and disengage the driving gear 2462 from the driven gear 2463; during the contraction process of the air cylinder 245, the gear 243 idles relative to the first rotating shaft 221 and will not drive the first rotating shaft 221 to rotate; after the air cylinder 245 completes the contraction, the gear 243 idles 180°, and the slot 2431 rotates to the position corresponding to the reset ejector rod 2466 again. The contact switch 2465 on the limiting block 2464 close to the material box 211 is in contact with the contact on the side wall of the limiting groove 247 again and makes the contact switch 2465 connected. The electromagnet 2467 is energized, the reset ejector rod 2466 extends, and the electromagnet attracts the magnetic block at the bottom of the slot 2431, so as to attract the gear 243 to move in the direction close to the limiting block 2464, so that the driving gear 2462 and the driven gear 2463 are meshed again and return to the normal coating state for the next rotation.

[0054] Furthermore, the edges of the sides where the driving gear 2462 and the driven gear 2463 approach each other are processed into rounded corners. When the sharing ring 222 and the coating plate 232 complete the rotation and the air cylinder 245 completes the contraction, and the contact switch 2465 and the electromagnet 2467 are connected, and the electromagnet attracts the gear 243 to move in the direction close to the limiting block 2464, the rounded corners provided at the edges of the driving gear 2462 and the driven gear 2463 can facilitate the insertion of the driving gear 2462 and the driven gear 2463.

[0055] Such as Figure 3, Figure 4 and Figure 7 As shown in Figure 4 and Figure 7 , in the embodiment of the present invention, the coating mechanism 2 further includes a cleaning component 25, and the cleaning component 25 includes a rotating rod 251, a screw rod 253 and a second motor 255. The rotating rod 251 is rotatably connected to the mounting cover 242. The rotating rod 251 is located directly above the first rotating shaft 221, and a cleaning brush 252 is provided on the rotating rod 251; the screw rod 253 is rotatably connected to the mounting cover 242. The screw rod 253 is located directly above the second rotating shaft 231, and a cleaning block 254 is threadedly connected to the screw rod 253. The cleaning block 254 is attached to the upper surface of the coating plate 232 located above; the second motor 255 is fixedly connected to the mounting cover 242, and the output shaft of the second motor 255 is connected to the screw rod 253, and the rotating rod 251 is in transmission connection with the screw rod 253.

[0056] Specifically, both ends of the rotating rod 251 and the screw rod 253 are rotatably connected to the mounting covers 242 on both sides. The rotating rod 251 and the screw rod 253 can be connected by belt drive. The second motor 255 is arranged in the mounting cover 242. When the second motor 255 is started, it can drive the screw rod 253 and the rotating rod 251 to rotate simultaneously. When the screw rod 253 rotates, it can drive the cleaning block 254 to slide along the length direction of the coating plate 232 to clean the coating plate 232; when the rotating rod 251 rotates, it can use the cleaning brush 252 to clean the distribution ring 222. By using the cleaning block 254 and the cleaning brush 252 to clean the coating plate 232 and the distribution ring 222 after rotation respectively, the coating accumulated on the coating plate 232 and the distribution ring 222 is cleaned up, which is convenient for the next rotation, so that the distribution ring 222 and the coating plate 232 in operation are always kept clean, which is beneficial to improving the coating uniformity.

[0057] Exemplarily, a limiting rod can be arranged above the screw rod 253. Both ends of the limiting rod are fixedly connected to the mounting covers 242 on both sides, and the limiting rod passes through the cleaning block 254. Through the limiting rod, the cleaning block 254 can only move along the length direction of the screw rod 253 and will not squeeze the coating plate 232 during the movement. In addition, a material receiving groove can be arranged on the mounting covers 242 on both sides. The cleaning block 254 can push the coating accumulated on the coating plate 232 to both ends of the coating plate 232 and drop into the material receiving groove, so as to avoid the cleaned coating from falling on the textile. At the same time, a baffle can also be arranged below the first rotating shaft 221 and the second rotating shaft 231. The baffle is fixedly connected to the conveying frame 1, and holes for the distribution ring 222 and the coating plate 232 to pass through are opened on the baffle. The coating residues cleaned by the cleaning brush 252 and the cleaning block 254 can fall on the baffle, so as to avoid the coating from directly falling on the textile.

[0058] Such as Figure 2 , Figure 3 and Figure 12As shown, in an embodiment of the present invention, the textile surface coating device further includes a first conveying roller 11 and a second conveying roller 12 provided at the inlet end of the conveying rack 1. A spreading assembly 3 is arranged between the first conveying roller 11 and the second conveying roller 12. The spreading assembly 3 includes a fixed seat 31, clamping blocks 32 and adjusting bolts 33. The fixed seat 31 is fixedly connected to the conveying rack 1; the clamping blocks 32 are movably connected to the fixed seat 31. There are two symmetrically arranged clamping blocks 32. The textile is located between the two clamping blocks 32. The side of the clamping block 32 close to the first conveying roller 11 bends away from the textile; the adjusting bolt 33 is rotationally connected to the fixed seat 31 and is threadedly connected to both clamping blocks 32. Screwing the adjusting bolt 33 can drive the two clamping blocks 32 to move in opposite directions.

[0059] Specifically, the height of the first conveying roller 11 is lower than the height of the second conveying roller 12. After the textile successively bypasses the first conveying roller 11 and the second conveying roller 12, it is continuously conveyed towards the coating mechanism 2, which is conducive to the complete unfolding of the textile before entering the coating mechanism 2, avoiding wrinkles and overlaps, and is conducive to the subsequent uniform coating by the coating mechanism 2. The two clamping blocks 32 clamp the textile in the middle. The distance between the two clamping blocks 32 gradually decreases along the textile conveying direction X. The end face of the clamping block 32 facing the textile is provided with an arc-shaped protrusion bending outward, which is convenient for spreading the wrinkled or overlapped textile. Screwing the adjusting bolt 33 can drive the two clamping blocks 32 to move in opposite directions to facilitate adapting to textiles of different thicknesses.

[0060] As Figure 3 As shown, in another embodiment of the present invention, the textile surface coating device further includes a dust suction mechanism 4. The dust suction mechanism 4 is arranged at the rear end of the second conveying roller 12. The dust suction mechanism 4 includes a vacuum cleaner 41 and an electrostatic adsorption roller 42. There are two vacuum cleaners 41, which are respectively arranged above and below the textile in a staggered manner; the electrostatic adsorption roller 42 is arranged at the rear end of the vacuum cleaner 41.

[0061] Specifically, the suction inlets of the vacuum cleaners 41 are close to or in contact with the upper and lower surfaces of the textile. The vacuum cleaners 41 can be used to clean the dust or debris on the surface of the textile, avoiding the dust being coated by the paint and affecting the quality of the textile. The electrostatic adsorption roller 42 is arranged above the textile. An energized electrostatic rod is arranged directly below the electrostatic adsorption roller 42 and below the textile. The electrostatic adsorption roller 42 can be used to adsorb the charged dust or hair sticking to the textile, improving the cleaning effect of the dust suction mechanism 4.

[0062] At the same time, the dust suction mechanism 4 may further include an atomizer 43. The atomizer 43 is used to spray mist on the textile to make the surface of the textile wet. On the one hand, it can effectively avoid dust adsorption, and on the other hand, it can facilitate the adhesion of the paint to the surface of the textile during subsequent coating.

[0063] Exemplarily, the textile surface coating device further includes a drying mechanism 5, which is arranged at the rear end of the coating mechanism 2 and is used for drying the coating on the surface of the coated textile to facilitate subsequent winding.

[0064] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
