By setting the water pipe 14 and the spray pipe 15, external cleaning water can enter the spray pipe 15 through the water pipe 14, and is sprayed downward by the nozzle on the spray pipe 15 to clean the polyester knitted fabric. For cleaning, a water tank 16 is fixedly installed on the bottom wall of the cleaning box 1. By setting the water tank 16, the water tank 16 can collect the cleaning water.

By setting the scrubbing mechanism 3 and the beating mechanism 5, the scrubbing mechanism 3 can scrub the upper and lower surfaces of the polyester knitted fabric entering the cleaning box 1, and the beating mechanism 5 can beat the polyester knitted fabric, so that the cleaning water on the polyester knitted fabric quickly falls into the water tank 16, which is convenient for subsequent drying of the polyester knitted fabric and improves the subsequent drying efficiency.

[0031] Two box doors 11 are hingedly installed on the other side of the cleaning box 1, and a drain pipe 17 is fixedly installed on the bottom wall of the water storage tank 16.

[0032] The feeding mechanism 2 includes two traction rollers 21 and two guide rollers 22. The two guide rollers 22 are rotatably mounted on the inner wall of the feed port 12. The two traction rollers 21 are rotatably mounted on the inner wall of the discharge port 13. By setting the two traction rollers 21 and the two guide rollers 22, when the two traction rollers 21 rotate synchronously in the opposite direction, the two traction rollers 21 can move and transmit the polyester knitted fabric. The two guide rollers 22 passively rotate to guide the polyester knitted fabric. One end of the two traction rollers 21 is fixedly mounted with a first gear 23. The two first gears 23 are meshed and connected. By setting the two first gears 23, the two traction rollers 21 can be brought into a synchronous reverse rotation state.

By turning on the servo motor 24, the driving shaft of the servo motor 24 can rotate the first rotating rod 25, and the first rotating rod 25 can rotate the fan gear 26. The fan gear 26 can drive the first gear 23 to rotate intermittently, so that the two traction rollers 21 intermittently rotate synchronously in the opposite direction, thereby realizing the intermittent movement transmission of the polyester knitted fabric.

The outer walls of the two upper rotating rollers 31 and the three lower rotating rollers 32 are fixedly mounted with a plurality of protrusions 33 distributed in a ring array. By arranging the two upper rotating rollers 31 and the three lower rotating rollers 32 and the protrusions 33, when the upper rotating rollers 31 and the lower rotating rollers 32 keep synchronously rotating in the opposite direction, the upper rotating rollers 31 and the lower rotating rollers 32 scrub the upper and lower surfaces of the polyester knitted fabric through the protrusions 33, thereby improving the cleaning efficiency. To improve the cleaning effect, a first transmission gear 34 is fixedly installed at one end of the two upper rotating rollers 31, and a first toothed belt 35 is installed between the two first transmission gears 34 for meshing transmission. By setting the first transmission gear 34 and the first toothed belt 35, the two upper rotating rollers 31 can keep rotating synchronously, and a second transmission gear 36 is fixedly installed at one end of the three lower rotating rollers 32, and a second toothed belt 37 is installed between the three second transmission gears 36 for meshing transmission. By setting the second transmission gear 36 and the second toothed belt 37, the three lower rotating rollers 32 can keep rotating synchronously.

[0034] A first transmission rod 38 is rotatably installed on the other side of the cleaning box 1, and a first synchronous wheel 39 is fixedly installed on one end of the first transmission rod 38 and one end of one of the upper rotating rollers 31, and a first synchronous belt 4 is transmission-installed between the two first synchronous wheels 39, and a second gear 41 is fixedly installed on one end of the first transmission rod 38 and one end of one of the lower rotating rollers 32, and the two second gears 41 are meshingly connected.

[0035] A second transmission rod 42 is rotatably installed on the other side of the cleaning box 1, and a third gear 43 is fixedly installed on the second transmission rod 42. The third gear 43 corresponds to the sector gear 26. By setting the third gear 43, when the sector gear 26 is disengaged from the first gear 23, it meshes with the third gear 43, and the second transmission rod 42 is rotated through the third gear 43. A second synchronous wheel 44 is fixedly installed on one end of the second transmission rod 42 and the other end of the first transmission rod 38. A second synchronous belt 45 is transmission-installed between the two second synchronous wheels 44. By setting the second synchronous wheel 44 and the second synchronous belt 45, when the second transmission rod 42 rotates, the second transmission rod 42 can rotate the first transmission rod 38 through the two second synchronous wheels 44 and the second synchronous belt 45.

[0036] The beating mechanism 5 includes a beating ball 51, a U-shaped seat 52 is fixedly installed on the side wall of the cleaning box 1, a rotating shaft 53 is rotatably installed on the U-shaped seat 52, a fixed sleeve 54 is fixedly installed in the middle of the rotating shaft 53, and a connecting plate 55 is fixedly installed on the outer wall of the fixing sleeve 54, one end of the connecting plate 55 is fixedly connected to the outer wall of the beating ball 51, and both ends of the rotating shaft 53 are sleeved with torsion springs 56, one end of the torsion spring 56 is fixedly connected to one end of the U-shaped seat 52, and the other end of the torsion spring 56 is fixedly connected to one end of the fixing sleeve 54. By pushing the connecting plate 55 to flip around the axis of the rotating shaft 53 as the center of the circle, the connecting plate 55 can make the beating ball 51 reciprocate up and down. When the beating ball 51 moves downward, it can beat the polyester knitted cloth, so that the excess cleaning water on the polyester knitted cloth quickly flows into the water storage tank 16. By setting the torsion spring 56, the torsion spring 56 can quickly reset the downward-turned connecting plate 55 upward through the fixing sleeve 54.

[0037] A second rotating rod 57 is rotatably installed on the other side of the cleaning box 1, and a cam 58 is fixedly installed on one end of the second rotating rod 57. An arc panel 59 is fixedly installed on the upper surface of the connecting plate 55. The cam 58 and the arc panel 59 correspond vertically. By driving the second rotating rod 57 to rotate, the second rotating rod 57 can rotate the cam 58, and the protruding part of the cam 58 can push the connecting plate 55 to flip downward through the arc surface of the arc panel 59.

[0038] The third synchronous wheel 6 is fixedly installed on the middle part of the first transmission rod 38 and the other end of the second rotating rod 57, and the third synchronous belt 61 is installed for transmission between the two third synchronous wheels 6. By setting the third synchronous wheel 6 and the third synchronous belt 61, when the first transmission rod 38 rotates, the first transmission rod 38 can rotate the second rotating rod 57 through the two third synchronous wheels 6 and the third synchronous belt 61.

[0039] The present invention also provides a polyester knitted fabric, which is prepared by using the production equipment for the polyester knitted fabric.

[0040] Working principle: When it is necessary to clean the semi-finished polyester knitted fabric, the operator first opens the two box doors 11, and then passes one end of the polyester knitted fabric between the two guide rollers 22, and then passes between the two upper rotating rollers 31 and the three lower rotating rollers 32, and then pulls one end of the polyester knitted fabric to pass the end of the polyester knitted fabric between the two traction rollers 21, and then closes the two box doors 11, and connects the external water delivery pump to the water delivery pipe 14, and the external water delivery pump delivers the cleaning water to the multiple spray pipes 15 through the water delivery pipe 14, and the cleaning water is sprayed downward through the nozzles on the multiple spray pipes 15 to rinse the polyester knitted fabric in the cleaning box 1;

[0041] At the same time, the operator turns on the servo motor 24, the driving shaft of the servo motor 24 rotates the first rotating rod 25, the first rotating rod 25 rotates the fan gear 26, and the fan gear 26 drives the corresponding first gear 23 to rotate intermittently. At this time, through the cooperation of the two first gears 23, the two traction rollers 21 intermittently rotate synchronously in the opposite direction. The two traction rollers 21 intermittently move and transmit the polyester knitted fabric during the intermittent synchronous reverse rotation, thereby conveniently realizing the intermittent transportation of the polyester knitted fabric, and further facilitating the further cleaning of the polyester knitted fabric during the stagnation process;

[0042] At the same time, when the sector gear 26 is disengaged from the first gear 23, the sector gear 26 meshes with the third gear 43, the sector gear 26 drives the third gear 43 to rotate, the third gear 43 rotates the second transmission rod 42, the second transmission rod 42 rotates the first transmission rod 38 through the two second synchronous wheels 44 and the second synchronous belt 45, the first transmission rod 38 rotates the two upper rotating rollers 31 synchronously in the same direction through the two first synchronous wheels 39, the first synchronous belt 4, the two first transmission gears 34 and the first toothed belt 35, the first transmission rod 38 rotates the three lower rotating rollers 32 synchronously in the opposite direction through the two second gears 41, the three second transmission gears 36 and the second toothed belt 37, at this time, the two upper rotating rollers 31 and the three lower rotating rollers 32 scrub the upper and lower surfaces of the polyester knitted fabric through the multiple protrusions 33, thereby conveniently realizing the synchronous scrubbing of the polyester knitted fabric during the rinsing process, thereby effectively improving the cleaning effect of the polyester knitted fabric;

[0043] At the same time, the first transmission rod 38 rotates the second rotating rod 57 through the two third synchronous wheels 6 and the third synchronous belt 61, and the second rotating rod 57 rotates the cam 58. The protruding part of the cam 58 pushes the connecting plate 55 to flip downward through the arc surface of the arc panel 59. The connecting plate 55 flips with the axis of the rotating shaft 53 as the center through the fixed sleeve 54, and at the same time, the two torsion springs 56 are deformed. The connecting plate 55 causes the beating ball 51 to move downward to beat the polyester knitted cloth, so that the excess cleaning water on the polyester knitted cloth quickly flows into the water storage tank 16, thereby conveniently realizing the dehumidification of the polyester knitted cloth after cleaning and improving the subsequent drying efficiency of the polyester knitted cloth.
