[0045] As Figure 2 and Figure 3 As shown in the figure, the brushing part 4 includes glue storage bin 41, which is slid up and down through slide column 411 and arranged inside the mounting frame 3, the mounting frame 3 is fixed with electric push rod 412 in the middle of the upper side, and the top end of the electric push rod 412 is fixedly connected with the glue storage bin 41, the inside of the glue storage bin 41 is symmetrically slidably provided with main baffle 42 in front and back, the back surfaces of the opposite faces of the two main baffles 42 are respectively provided with rectangular sliding grooves, the rectangular sliding grooves of the main baffles 42 are provided with return springs 421, the upper ends of the auxiliary baffles 422 are slidably arranged in the rectangular sliding grooves of the main baffles 42, and the left and right side surfaces of the auxiliary baffles 422 are respectively slidably provided with blocking blocks 423, the front and back side surfaces of the glue storage bin 41 are respectively provided with rectangular sliding grooves, the front and back ends of the glue roller 43 are respectively rotatably installed in the rectangular sliding grooves of the glue storage bin 41, and the rectangular sliding grooves of the glue storage bin 41 are provided with return springs 431, the lower side of the glue storage bin 41 is a rectangular opening, the initial position of the glue roller 43 closes the rectangular opening, the lower side and the left and right side surfaces of the inside of the glue storage bin 41 are respectively provided with glue outlets, the blocking blocks 423 are matched with the outlines of the glue outlets and can move forward and backward in the glue outlets.

[0046] The glue roller 43 of the brushing part 4 is used for brushing PA glue on the polyester fabric to be glued. In work, PA glue is added between the two main baffles 42 of the glue storage bin 41 in a manual manner. When the conveying belt 2 drives the polyester fabric to be glued to pass from the lower side of the glue roller 43, the glue roller 43 rotates by friction and moves upward to press the return spring 431. The glue roller 43 also compresses the reset spring 421 through the auxiliary baffle 422. At the same time, the rectangular opening of the glue storage bin 41 will be opened, so that the PA glue flows out through the glue outlet groove. The rotating glue roller 43 can uniformly apply the PA glue to the surface of the polyester fabric to be glued. In non-working state, the return spring 431 pushes the glue roller 43 to keep in the initial position, preventing the rectangular opening of the glue storage bin 41 from leaking glue. The reset spring 421 pushes the lower side of the auxiliary baffle 422 to tightly fit the outer side of the glue roller 43. The block 423 can block the glue outlet grooves on the left and right sides of the auxiliary baffle 422 to prevent the PA glue from flowing to the back surface between the two auxiliary baffles 422. The glue roller 43 can be pressed on the polyester fabric to be glued to the extent by the electric push rod 412. The size of the rectangular opening is adjusted, and the amount of PA glue flowing out of the glue outlet groove is changed, so that the glue thickness of the glue roller 43 is controlled, and the glue application effect and applicability of the glue roller 43 are increased.

[0047] It should be noted that the left and right sides of the auxiliary baffle 422 are tightly fitted between the lower inner wall of the glue storage bin 41, and the lower side of the auxiliary baffle 422 is tightly fitted with the outer side of the glue roller 43 to prevent glue leakage.

[0048] As shown in Figure 4 , the main baffle 42 is rotatably installed with a moving gear 45 at the upper end. The moving gear 45 is fixedly connected with a rotating rod 451. The left end of the rotating rod 451 extends out of the glue storage bin 41. A rack 452 is fixedly arranged on the inner top surface of the glue storage bin 41. The moving gear 45 is in meshing transmission with the rack 452. In work, the left end of the rotating rod 451 can be manually rotated to drive the moving gear 45 to mesh with the rack 452, so that the main baffle 42 can move left and right, and the width of the PA glue added in the glue storage bin 41 and the glue receiving area of the glue roller 43 are changed, so that the glue application width of the glue roller 43 can be adjusted, and the applicability of the glue application of the glue roller 43 is increased.

[0049] It should be noted that, referring to Figure 4 , a rectangular groove is formed in the left side of the glue storage bin 41. Two sliding blocks are slidably arranged in the rectangular groove. The rotating rod 451 passes through the sliding blocks. Elastic limiting protrusions are arranged on the sliding blocks. The rectangular groove is provided with clamping grooves matched with the elastic limiting protrusions, which are not shown in the figure. When the rotating rod 451 is rotated, the elastic limiting protrusions need to be pressed down and moved to a set position, and then the elastic limiting protrusions are released to be clamped with the clamping grooves, so as to limit the main baffle 42 and prevent the problem of sliding.

[0050] As Figure 4 shown, the left side of the storage compartment 41 is hinged to the upper end of the hinge rod 46, the lower end of the hinge rod 46 is rotatably connected to the front and rear ends of the roller 461, and the middle part of the hinge rod 46 is hinged to the lower end of the left side of the storage compartment 41 through the tension spring 462. When the conveyor belt 2 drives the coated polyester fabric to pass from the lower side of the roller 461, the roller 461 spreads the PA glue again to increase the flatness of the glue layer. The tension spring 462 is used to pull the roller 461 to adhere to the coated polyester fabric, thereby increasing the flattening ability of the roller 461.

[0051] As Figure 5 , Figure 6 , Figure 8 and Figure 12 shown, the right side of the storage compartment 41 is fixed with a mounting frame 44, the inside right side of the mounting frame 44 is slidably installed with a toothed frame 441 on the front and rear sides, the inside of the toothed frame 441 is distributed with meshing teeth, the gear shaft 442 passes through the toothed frame 441 and is installed on the mounting frame 44, the rear end of the gear shaft 442 is connected and driven by the motor 443 through the shaft coupling, the incomplete gear 444 is symmetrically fixed on the gear shaft 442, the incomplete gear 444 is respectively engaged and driven with the meshing teeth in the toothed frame 441, the left end of the toothed frame 441 is hinged to the upper end of the connecting rod 445, the lower end of the connecting rod 445 is hinged to the slide rod 446, the mounting frame 44 is provided with inclined sliding grooves on the front and rear sides, the slide rod 446 is slidably arranged in the inclined sliding grooves, the upper blade 447 is arranged on the lower side of the slide rod 446 through the spring rod 448, the shovel plate 449 is fixed inside the mounting frame 44 and below the upper blade 447, the shovel plate 449 is divided into an inclined structure in the middle part and a flat and pointed guide section at the end part, as Figure 12 shown, the guide section of the shovel plate 449 is uniformly provided with notches, and the above structure of the shovel plate 449 can scrape and push the impurities on the fabric to the inclined structure.

[0052] The upper blade plate 447 of the brushing part 4 cooperates with the shovel plate 449 to clean the debris, fuzz balls and other impurities on the polyester fabric to be coated before coating. In operation, the motor 443 is started, the gear shaft 442 rotates and alternately engages with the meshing teeth inside the tooth frame 441 through the incomplete gear 444, so that the tooth frame 441 moves back and forth, the tooth frame 441 pulls the slide rod 446 to move up and down along the inclined sliding groove of the mounting frame 44, when the conveying belt 2 drives the polyester fabric to be coated to pass through the shovel plate 449, the shovel plate 449 shovels the debris, fuzz balls and other impurities on the polyester fabric to be coated to the slide rod 446, the slide rod 446 moves downward along the inclined sliding groove, so that the upper blade plate 447 is located at the intersection of the inclined structure of the shovel plate 449 and the guide section and moves to the left, and then the debris, fuzz balls and other impurities shovelled by the shovel plate 449 are separated from the coated polyester fabric, wherein the spring rod 448 enables the upper blade plate 447 and the shovel plate 449 to be in flexible contact, preventing the shovel plate 449 from being damaged under pressure.

[0053] It should be noted that in other embodiments, the position of the slide rod 446 can be lifted when it moves to the right, so that the upper blade plate 447 and the shovel plate 449 are in a separated state when the slide rod 446 moves to the right, preventing the slide rod 446 from pushing the impurities accumulated on the shovel plate 449 out when it moves to the right. The specific structure of the above function is described as follows Figure 14 and Figure 15 The mounting frame 44 rear side is fixed with a layered plate 6, which is divided into a guide section and a fixed section, the guide section of the layered plate 6 extends into the inclined sliding groove of the mounting frame 44, and the lower end of the layered plate 6 is hinged with an inclined guide plate 7, which is lifted by the slide rod 446 when it slides downward, and passes through when the slide rod 446 slides from the lower left end to the upper right end of the inclined sliding groove, so that the upper blade plate 447 is lifted when the slide rod 446 moves upward to reset, avoiding the upper blade plate 447 from pushing the impurities out of the shovel plate 449.

[0054] As shown in Figure 7 and Figure 8 The inclined upper side of the shovel plate 449 is provided with a sweeping roller 47, which is distributed with a plurality of groups of flexible bristles, the sweeping roller 47 is rotatably installed in the mounting frame 44, the front end of the sweeping roller 47 is fixedly connected with a driven gear 471, a driving gear 472 is fixedly connected with the front end of the gear shaft 442, and the driving gear 472 and the driven gear 471 are connected and driven through a belt, in operation, the rotation of the gear shaft 442 drives the driving gear 472, the driving gear 472 drives the driven gear 471 through the belt, and the driven gear 471 drives the sweeping roller 47 to rotate clockwise, the rotating sweeping roller 47 sweeps the debris, fuzz balls and other impurities separated from the upper blade plate 447 to the left side of the mounting frame 44 for collection, increasing the effect of cleaning the debris, fuzz balls and other impurities.
