Description

Technical Field

[0001] This invention relates to the field of winding device technology, specifically a winding device for producing weft-knitted base fabric with self-adjusting tension function. Background Technology

[0002] Weft-knitted base fabric is a widely used woven substrate in the automotive interior industry. It is usually made of synthetic fiber materials such as polyester filament or nylon, which are wound in a loop along the width of the fabric to form loops. Each loop is formed continuously by one or more needles. Compared with warp-knitted fabric, weft-knitted fabric has better elasticity, softness and extensibility, so it is suitable for applications that need to be worn close to the body or have certain elasticity requirements. At present, in the process of fabric production, manual winding is usually used. It is difficult to control the tension of the fabric roll during manual winding, which can cause the fabric roll to have indentations or collapse, affecting the quality of the product. At the same time, manual winding is labor-intensive and has low winding efficiency. Summary of the Invention

The second pawl then rests against the second ratchet, which drives the intermediate gear to rotate. The intermediate gear drives the fourth gear to rotate, which in turn drives the take-up roller to rotate. The take-up roller then winds up the fabric. When the fabric winding is complete, the fourth motor is reversed, driving the first and second rotating plates to rotate in reverse. The first rotating plate drives the first pawl to rotate, which in turn drives the first ratchet to rotate. The first ratchet drives the switching disc to rotate, at which point the first pawl rests against the first ratchet. The second rotating plate drives the second pawl to rotate, and the second pawl slides on the second ratchet. The switching disc then rotates the full fabric cylinder to the next winding position.

[0038] Working principle of the invention:

[0039] The control system starts the first motor 23, which drives the conveyor belt 22 and the first pinion to rotate. The conveyor belt 22 transports the fabric out. The first pinion drives the first belt 25 to rotate, which in turn drives the second pinion 28 to rotate. The second pinion 28 drives the first gear 24 to rotate, which in turn drives the second gear 26 to rotate. The second gear 26 drives the third gear and the first cleaning roller 27 to rotate, which in turn drives the second cleaning roller to rotate. The rotation speeds of the first and second cleaning rollers are different from those of the conveyor belt 22. The first and second cleaning rollers sweep the dust adhering to the synthetic fiber fabric toward the suction fan 33, sweeping the dust that is difficult to be directly sucked up by the suction fan 33 into the air, making it easier for the suction fan 33 to suck up the dust and clean the fabric. The control system starts the second motor, which drives the first lead screw 32 to rotate. The first lead screw 32 drives the first slider to slide on the first lead screw 32, which in turn moves the suction fan 33. The suction fan 33 absorbs the dust brushed off the fabric by the soft brush into the waste box 39.

[0040] When a roll needs to be changed, the suction fan 33 is controlled to increase the airflow, and the suction fan 33 sucks up the fabric. The third motor is controlled to start the second lead screw 35 to rotate. The second lead screw 35 drives the second slider to slide on the second lead screw 35. The second slider drives the fabric cutter 36 and the glue sprayer 37 to move. The fabric cutter 36 cuts the fabric, and at the same time, the glue sprayer 37 sprays glue on one side of the fabric. After the cutting is completed, the second motor is controlled to start, so that the suction fan 33 moves the fabric to the empty fabric tube and sticks the fabric to the fabric tube.

[0041] When the fabric is wound, the fourth motor 43 is activated. The fourth motor 43 drives the first rotating plate 45 and the second rotating plate 48 to rotate. The first rotating plate 45 drives the first pawl to rotate, at which point the first pawl slides on the first ratchet. The second rotating plate 48 drives the second pawl to rotate, and the second pawl drives the second ratchet to rotate. At this point, the second pawl abuts against the second ratchet, and the second ratchet drives the intermediate gear 47 to rotate. The intermediate gear 47 drives the fourth gear to rotate, and the fourth gear drives the take-up roller 46 to rotate. The take-up roller 46 winds up the fabric. The fourth gear drives the sixth gear 53 to rotate, and the sixth gear 53 drives the first rotating shaft to rotate. The first rotating shaft drives the torsion spring to store energy, and the first rotating shaft drives the fourth pinion 59 to rotate. The pinion 59 drives the fifth pinion 54 to rotate, the fifth pinion 54 drives the second rotating shaft to rotate, the second rotating shaft drives the first bevel gear 58 to rotate, the first bevel gear 58 drives the second bevel gear 55 to rotate, the second bevel gear 55 drives the third lead screw 56 to rotate, and the third lead screw 56 drives the third slider 571 to slide on the third lead screw 56. As the fabric is wound up, the height increases accordingly. When the tension of the fabric roll changes, the floating plate 574 slides inside the first limit block 573. The floating plate 574 drives the lever 575 to rotate around the support column. The lever 575 drives the tension roller 576 to slide in the arc groove 577, adjusting the pressure of the tension roller 576 on the fabric roll so that the tension of the fabric roll is maintained within a suitable range.

[0042] When the fabric winding is complete, the fourth motor 43 is reversed. The fourth motor 43 drives the first rotating plate 45 and the second rotating plate 48 to reverse. The first rotating plate 45 drives the first pawl to rotate, the first pawl drives the first ratchet to rotate, and the first ratchet drives the switching disc 42 to rotate. At this time, the first pawl abuts against the first ratchet, and the second rotating plate 48 drives the second pawl to rotate. At this time, the second pawl slides on the second ratchet. The switching disc 42 drives the full fabric cylinder to the lower winding position. When the take-up roller 46 switches, the torsion spring releases energy and drives the third slider 571 back to the initial position. Starting from the initial position, the switching disk 42 drives the cylinder to rotate, which in turn drives the intermittent gear 491 to rotate. The intermittent gear 491 drives the fifth gear 492 to rotate, which in turn drives the third pinion 494 to rotate. The third pinion 494 drives the second belt 493 to rotate, which in turn drives the sixth pinion 64 to rotate. The sixth pinion 64 drives the third pawl to rotate, which in turn drives the third rotating plate to rotate. The third rotating plate drives the third rotating shaft to reverse, which in turn drives the rotating cylinder 67 to reverse. The rotating cylinder 67 then lifts the weight block back to the initial position.

[0043] When the full fabric cylinder rotates to the lower roll position, the fabric cylinder drives the trigger block 682 to rotate on the base frame 681. The trigger block 682 drives the fourth rotating shaft to rotate, which in turn drives the seventh gear and the rotating block 687 to rotate. The rotating block 687 drives the extension block to rotate, which in turn compresses the arc spring 688. The seventh gear drives the eighth gear 684 to rotate, and the eighth gear 684 drives the rack 685 to move downward within the second limit block 689. The rack 685 drives the fourth pawl to move downward, disengaging the fourth pawl from the fourth ratchet 686. The weight block then drives the rotating drum 67 to rotate. The rotating drum 67 then... The third rotating shaft rotates, which drives the fourth lead screw to rotate. The fourth lead screw drives the fourth slider to slide within the track 65. The fourth slider drives the push block 66 to push the fabric tube along the take-up roller 46, thus unloading the fabric tube. When the full take-up roller 46 rotates and approaches the trigger block 682, the intermittent gear 491 disengages from the fifth gear 492. When the fabric tube rotates away from the unwound position, the arc spring 688 drives the extension plate to reverse, which in turn drives the rotating block 687 to reverse. The rotating block 687 drives the fourth rotating shaft to reverse, and the fourth rotating shaft drives the trigger block 682 to rotate back to the initial position.

Those skilled in the art can still modify the technical solutions described in the foregoing embodiments.
