[0002] Fabric sanding machine is an important equipment for fabric finishing, which can grind the fabric surface to produce fluff. The sand roller sanding mechanism on the market uses sandpaper with sharp diamond grains on the surface to repeatedly rub the fabric surface, so that short and dense fluff is produced on the fabric surface to complete the sanding finishing. However, there is no dust suction or dust removal unit in the sand roller sanding mechanism, which makes the fabric surface not clean enough, and causes fluff or dust to fill the working environment, resulting in a poor working environment and affecting the health of the staff.

[0003] In response to the above technical problems, a Chinese invention patent with authorization announcement number CN106012402A discloses a sanding roller type sanding mechanism for fabrics, in which a sanding box is provided with a tension adjusting roller, a sanding roller group, a cloth pressing roller group, a transmission unit, an adsorption bin and an adsorption fan, the feeding roller feeds the fabric to the tension adjusting roller, and the fabric is fed to between the sanding roller group and the cloth pressing roller group via the tension adjusting roller, the sanding roller group includes a plurality of sanding rollers distributed at equal intervals and in close contact with the lower surface of the fabric, the cloth pressing roller group includes a plurality of cloth pressing rollers distributed at equal intervals and in close contact with the upper surface of the fabric, the transmission unit is arranged in the sanding box above the cloth pressing roller group, the adsorption bin is arranged in the sanding box below the sanding roller group, and the adsorption fan is arranged at the bottom of the adsorption bin.

[0004] Although the above invention can absorb the fluff or dust generated by the friction of the sand roller on the surface of the fabric, thereby improving the cleanliness of the fabric and the working environment, the fluff is too fluffy and the storage structure of the adsorption fan can only store a small amount of fluff. Workers need to frequently transfer the fluff out of the storage structure or replace the storage structure to ensure the continuous operation of the above adsorption fan. Utility Model Content

[0025] The waste compression collection device 5 includes a collection hopper 51 fixed inside the chassis 1 and in a prism shape, a U-shaped box body 52 connected to the lower end outlet of the collection hopper 51, a rotating shaft 53 rotating inside the U-shaped box body 52, a rotating assembly 54 driving the rotating shaft 53 to rotate intermittently, a plurality of blades 531 vertically connected to the side wall of the rotating shaft 53 and uniformly surrounding the axis of the rotating shaft 53, a compression hopper 55 fixed to one side of the U-shaped box body 52 and in a truncated cone shape, a fan-shaped through hole 521 opened on one side wall of the U-shaped box body 52 and connecting it with the inside of the compression hopper 55, and a push rod 56 slidably plugged into the other side wall of the U-shaped box body 52 , a fan-shaped push plate 57 fixed to one end of the push rod 56 and located inside the U-shaped box body 52, and a reciprocating push component 58 that drives the push rod 56 to push the fan-shaped push plate 57 to slide reciprocatingly relative to the U-shaped box body 52. ​​The bottom of the U-shaped box body 52 is semicircular and coaxial with the rotating shaft 53. The blade 531 is rectangular, and its three sides respectively slide in contact with the inner wall of the U-shaped box body 52. ​​The fan-shaped push plate 57, the fan-shaped through hole 521 and the gap between adjacent blades 531 on the rotating shaft 53 are of the same shape and are located directly below the rotating shaft 53. The inner wall of the U-shaped box body 52 is provided with a fan-shaped groove 522 for accommodating the fan-shaped push plate 57.

[0026] Among them, a partition 14 is fixedly arranged at the connection between the collecting hopper 51 and the U-shaped box body 52 inside the chassis 1, and the rotating component 54, the reciprocating driving component 58 and the compression hopper 55 are all located below the partition 14, which can prevent the fluff from falling onto the transmission components such as the rotating component 54 and the reciprocating driving component 58, affecting the transmission safety of the transmission components; an inspection port 18 is opened on the front of the chassis 1, and a pair of glass doors 7 for opening and closing the inspection port 18 are hingedly installed on the front of the chassis 1, and handles 71 and door locks 72 are fixedly installed on the two glass doors 7, which not only allows the staff to conveniently inspect the parts inside the chassis 1, but also allows the staff to clean the fluff and dust inside the chassis 1 in time.

By adopting the sliding connection structure of the sliding baffle 6 and the L-shaped plate 13, when the compression hopper 55 is full and the fluff is compressed too much, the sliding baffle 6 is pulled out from between the two L-shaped plates 13, so that part of the fluff can be released in time to prevent the compression hopper 55 from having insufficient space; when the compression hopper 55 is not full and the fluff is not completely compressed, the sliding baffle 6 is inserted back between the two L-shaped plates 13 to prevent the fluff from overflowing from the discharge port of the compression hopper 55.

[0028] like Figure 2 , Figure 3 As shown, the rotating assembly 54 includes a rotating shaft 2 541 rotating in the chassis 1, a motor 2 542 fixed on the chassis 1 and having an output end connected to the rotating shaft 2 541, an incomplete driving gear 1 543 fixed on the rotating shaft 2 541, a rotating shaft 3 544 rotating in the chassis 1 and parallel to the rotating shaft 2 541, a driven gear 1 545 fixed on the rotating shaft 3 544 and capable of meshing with the incomplete driving gear 1 543, a worm 546 fixed on the rotating shaft 3 544, and a worm wheel 547 fixed on the rotating shaft 1 53 and meshing with the worm 546. One end of the rotating shaft 1 53 rotates to pass through the side wall of the U-shaped box body 52 and is fixedly connected to the worm wheel 547. The motor 2 542 is fixed on The outer wall of the chassis 1, and the output end passes through the side wall of the chassis 1 to connect the rotating shaft 2 541; the reciprocating pushing assembly 58 includes an incomplete driving gear 2 581 fixed on the rotating shaft 2 541, a rotating shaft 4 582 rotating inside the chassis 1, a driven gear 2 583 fixed on the rotating shaft 4 582 and meshing with the incomplete driving gear 2 581, a crank 584 with one end fixedly hinged to the rotating shaft 4 582, and a connecting rod 585 with the other end of the crank 584 and one end of the push rod 56 movably hinged at both ends, the length of the connecting rod 585 is greater than the width of the U-shaped box body 52, and the meshing teeth of the incomplete driving gear 1 543 and the meshing teeth of the incomplete gear 2 are respectively located on both sides of the axis of the rotating shaft 2 541.

[0029] By adopting the above technical solution, when the motor 2 542 drives the rotating shaft 2 541 to rotate, first the meshing teeth on the incomplete driving gear 1 543 on the rotating shaft 2 541 will rotate and mesh with the driven gear 1 545, so that the driven gear 1 545 drives the rotating shaft 3 544 and the worm 546 to rotate, and then the worm 546 will rotate and mesh with the worm wheel 547, so that the worm wheel 547 drives the rotating shaft 1 53 to rotate, and after a round of rotation and meshing of the meshing teeth on the incomplete driving gear 1 543 and the driven gear 1 545 is completed, at this time, a pair of adjacent blades 1 531 on the rotating shaft 1 53 just rotate to the two sides of the fan-shaped opening and keep this position unchanged, and at the same time, the meshing teeth on the incomplete gear 2 on the rotating shaft 2 541 will start to rotate and mesh with the driven gear 1 545. The driven gear 2 583 causes the driven gear 2 583 to drive the rotating shaft 4 582 to rotate, and then the crank 584 fixedly hinged to the rotating shaft 4 582 will flip with it as the rotation center, and drive the connecting rod 585 to pull or push the push rod 56. After a round of rotational meshing between the teeth on the incomplete gear 2 and the driven gear 2 583 is completed, the driven gear 2 583 will rotate exactly one circle, and at the same time, the connecting rod 585 pulls or pushes the push rod 56 to intersperse the side wall of the U-shaped box body 52 back and forth, thereby achieving the effect of the fan-shaped push plate 57 pushing the fluff and automatically returning to the fan-shaped groove 522. Finally, the teeth on the incomplete active gear 1 543 and the driven gear 1 545 start the next round of rotational meshing, thereby starting the subsequent transfer of the fluff.

[0030] like Figure 2 , Figure 3 As shown, a support seat 15 and a support seat 2 16 are fixedly arranged at the bottom of the partition 14, the rotating shaft 2 541 rotates through the supporting seat 15, and the incomplete driving gear 1 543 and the incomplete driving gear 2 581 on the rotating shaft 2 541 are respectively located on both sides of the supporting seat 1 15, the rotating shaft 3 544 rotates through the supporting seat 2 16, and the driven gear 1 545 and the worm 546 on the rotating shaft 3 544 are located on the same side of the supporting seat 2 16, and a support seat 3 17 is fixedly arranged at the bottom of the chassis 1, the rotating shaft 4 582 rotates through the supporting seat 3 17, and the driven gear 2 583 and the crank 584 on the rotating shaft 4 582 are respectively located on both sides of the supporting seat 3 17. By adopting the above-mentioned supporting seat 15, supporting seat 2 16 and supporting seat 3 17, the rotation of each shaft in the rotating assembly 54 and the reciprocating driving assembly 58 can be stably supported, thereby ensuring the transmission stability of the transmission components in the two.

[0031] like Figure 3As shown, one end of the rotating shaft 1 53 rotates out of the side wall of the U-shaped box body 52 and penetrates into the compression hopper 55. The rotating shaft 1 53 is located on the side of the compression hopper 55 and is evenly and vertically connected with a plurality of right-angled trapezoidal blades 2 532. The top and inclined surface of the blade 2 532 are parallel to the inner wall of the compression hopper 55, and each blade 2 532 is aligned with the blade 1 531 in sequence. By adopting the above-mentioned blade 2 532, when the stirring shaft rotates, the blade 1 531 and the blade 2 532 will rotate synchronously, and at the same time, the fluff transferred to the fan-shaped opening by the adjacent blade 1 531 will be stuffed into the gap of the corresponding adjacent blade 2 532 by the fan-shaped push plate 57, and then taken away from the fan-shaped opening by the blade 2 532, so as to ensure that the fluff is evenly distributed in the compression hopper 55, and prevent the fluff from accumulating too much at the fan-shaped opening in the early stage of filling the compression hopper 55, thereby affecting the subsequent entry of the fluff.

[0032] like Figure 4 As shown, the synchronous drive device 4 includes a motor 41 fixed on the chassis 1 and connected to a sanding roller 3 at its output end, a plurality of transmission gears 42 respectively fixedly mounted on one end of the sanding roller 3, a plurality of transmission pinions 43 rotating on the side wall of the chassis 1 and located between the gaps of the transmission gears 42, the transmission pinions 43 respectively meshing with two adjacent transmission gears 42, the motor 41 and the transmission gear 42 respectively located on both sides of the chassis 1, and the two ends of the sanding roller 3 respectively rotate through the two side walls of the chassis 1 to connect the motor output end and the transmission gear 42. By adopting the above-mentioned synchronous drive device 4, it is possible to effectively ensure that each sanding roller 3 rotates synchronously and stably.

[0033] The working principle of this embodiment:

[0034] When the fabric needs to be polished, first pass the fabric through the fabric inlet 11 and the fabric outlet 12 of the chassis 1, and make the conveying roller 2 and the sanding roller 3 located at the upper and lower sides of the fabric respectively. Since the outer diameter of the conveying roller 2 is smaller than the outer diameter of the sanding roller 3, and the lowest point of the conveying roller 2 is lower than the highest point of the sanding roller 3, the lower surface of the fabric will be close to the top of each sanding roller 3, and then the motor 41 drives a sanding roller 3 to rotate, so that the transmission gear 42 at one end of the sanding roller 3 rotates to engage the transmission pinion 43, and then the transmission pinion 43 will rotate to engage the transmission gear 42 at one end of the other sanding roller 3, so that the sanding roller 3 rotates together, and preferably by analogy, each sanding roller 3 will rotate synchronously in the opposite direction of the fabric conveying, so as to quickly polish the lower surface of the fabric; at the same time, the fluff polished off the fabric will naturally fall into the collecting hopper 51, and then the rotating component 54 drives the rotating shaft 53 in the U-shaped box body 52 to rotate, so that each blade 531 will The fluff accumulated at the bottom outlet of the collecting hopper 51 is transferred to the bottom of the U-shaped box body 52 until a pair of adjacent blades 531 and the two sides of the fan-shaped through hole 521 or the fan-shaped push plate 57 are aligned, the rotating assembly 54 stops working, and the reciprocating pushing assembly 58 drives the push rod 56 to extend into the U-shaped box body 52, and then the push rod 56 pushes the fan-shaped push plate 57 in the U-shaped box body 52 to leave the fan-shaped groove 522 and slide relative to the gap between the adjacent blades 531, and the adjacent blades 531 are located at the adjacent blades. The fluff between the collecting hopper 51 and 531 will be pushed into the compression hopper 55 from the fan-shaped opening by the fan-shaped push plate 57. When the fan-shaped push plate 57 is flush with the fan-shaped opening, the reciprocating push assembly 58 will reversely drive the push rod 56 to exit the U-shaped box body 52, so that the fan-shaped push plate 57 returns to the fan-shaped groove 522 again to prepare for subsequent work. Finally, by analogy, the fluff that falls into the collecting hopper 51 will be continuously transferred and stuffed into the compression hopper 55, thereby achieving the effect of compressing and storing the fluff.
