Description

Technical Field

[0001] The invention relates to the technical field of coating devices, in particular to a non-woven fabric surface coating and gluing system. Background Art

[0002] Weftless fabric is a flexible composite material with unidirectionally arranged fibers. It uses imported ultra-high-strength fibers as raw materials, and is made by applying special equipment technology and environmentally friendly special matrix through precision technology. In the weftless fabric production line, a gluing device is needed to gluing the fibers to achieve subsequent film laying and composite processing. The existing gluing devices generally impregnate or surface coat the fibers, but both of these gluing methods have certain disadvantages in actual processing. The surface coating method is to apply the adhesive to the fiber surface with a brush or roller. During the gluing process, uneven coating often occurs, affecting the subsequent composite processing; while the dipping gluing is to immerse the fibers in the adhesive so that they are fully in contact with the adhesive. Although this method is evenly coated, the soaked fibers will drip adhesive during the transmission process, and the production line needs to be cleaned frequently, which is time-consuming and labor-intensive.

[0003] With the iteration of technology, a coating and gluing device for recovering excess glue on the surface of the weftless fabric has been derived. Specifically, a glue roller is connected and rotated horizontally below the liquid level of the glue in the glue pool. The weftless fabric enters the glue pool at a certain angle and obliquely downward, bypasses the outer wall of the rotating glue roller, and then moves out at an oblique upward path. The weftless fabric moved out of the glue pool will pass through the pressure roller. The pressure rollers on both sides of the weftless fabric can squeeze out excess glue. Since the pressure roller is placed horizontally, the angle formed by the outer wall of the pressure roller and the direction of the weftless fabric will retain overflowed glue. The glue is difficult to flow out under the action of gravity due to the obstruction of the weftless fabric or the outer wall of the pressure roller. Over a long period of time, the glue at the angle will solidify. On the one hand, the solidified glue will contaminate the surface of the weftless fabric, causing product defects and uneven coating. On the other hand, it will cause the rotation of the pressure roller to be blocked, affecting the production of the weftless fabric. Summary of the invention

[0004] In order to make up for the shortcomings of the prior art, the present invention proposes a surface coating and gluing system for the weftless cloth. The present invention drives two vertical transition columns to rotate through a motor, so that the excess glue adhered to the weftless cloth on the transition columns can drip under the action of its own gravity. The dripped glue is thrown out by centrifugal force and gathered at the bottom wall position inside the gluing barrel, thereby realizing timely and effective recovery of the excess glue on the weftless cloth, avoiding waste and pollution caused by the glue dripping from the weftless cloth removed from the gluing barrel.

After releasing the two transition columns 3, the first spring 63 and the second spring 18 begin to reset, and the first spring 63 will push the bottom block 6 to slide in the bottom groove 13, so that the two bottom blocks 6 approach each other along the corresponding bottom groove 13, the two bottom blocks 6 will drive the two bottom rods 61 and the bottom gear 62 to approach each other, and the two bottom rods 61 will drive the two rounded tables 2 and the transition column 3 to approach each other during the process of approaching each other, so that the non-weft fabrics on the outer walls of the two transition columns 3 are in contact with each other, and are suitable for non-weft fabrics of different thicknesses. The second spring 18 pushes the tensioning block 15 to slide away from the motor 5 in the tensioning groove 14, and the tensioning block 15 will drive the tensioning rod 16 and the slave gear 17 on the tensioning rod 16 away from the main gear 51, so that the chain 52 is tightened again, completing the loading process of the non-weft fabric; The rubber material is transported to the rubber barrel 1 along the material change joint 12. A heating unit is provided in the rubber barrel 1 to heat the rubber material in the rubber barrel 1 to ensure the fluidity of the rubber material in the rubber barrel 1. The liquid surface of the rubber material is flush with the upper end of the rounding table 2, so that the non-woven fabric on the outer wall of the rounding table 2 is immersed in the rubber material. As the motor 5 rotates, the motor 5 drives the main gear 51 to rotate. During the rotation of the main gear 51, the chain 52 is driven to transmit.

[0032] In this embodiment, the square groove 21 is slidably and sealingly connected to the square rod 22; the bottom rod 61 is rotationally and sealingly connected to the bottom block 6; a folding bladder 64 is sleeved on the outer wall of the first spring 63; one end of the folding bladder 64 is connected to the bottom block 6, and the other end is connected to the wall of the bottom groove 13; the inside of the folding bladder 64 is communicated with the inside of the square groove 21 through a third air duct 65. Before the weft-free fabric is wrapped around the outer wall of the right truncated table 4, the transition column 3 and the inverted truncated table 2, the two right truncated tables 4 are lifted upwards. The upward movement of the two right truncated tables 4 will drive the transition column 3 upwards, and the upward movement of the two transition columns 3 will drive the inverted truncated table 2 upwards, so that the square rod 22 and the square groove 21 slide vertically, and negative pressure is formed during the expansion of the internal space of the square groove 21, so that the gas inside the folding bag 64 enters the square groove 21 along the third airway 65, so that the folding bag 64 overcomes the first spring 63 and starts to shrink, so that the two bottom blocks 6 slide along the bottom groove 13 and overcome the elastic force of the first spring 63, and the two bottom blocks 6 will drive the corresponding bottom bars 61 to move away from each other, and the two bottom bars 61 will drive the two square bars 22 to move away from each other, and the two square bars 22 will drive the transition columns 3 to move away from each other, so that the gap between the two transition columns 3 is increased, which is convenient for loading the non-weft cloth. After the non-weft cloth is wound, the right circular table 4, the transition column 3 and the inverted circular table 2 are released, and the three move downward under the action of gravity, and the gas in the square groove 21 is squeezed by the square rod 22 and enters the folding bag 64 along the third air channel 65, so that the folding bag 64 is unfolded, and the two bottom blocks 6 are close to each other, and the two transition columns 3 are also close to each other.

[0033] Embodiment 5: A limiting component is provided on the outer wall of the right circular table 4 and the inverted circular table 2 to limit the weft-free cloth, and the limiting component is rotatably connected to the outer wall of the right circular table 4 and the inverted circular table 2.
