Description

Technical Field

[0001] The invention relates to the field of cloth transmission, and in particular to a cloth feeding device and a cloth feeding method for mosquito repellent gauze cloth. Background Art

[0002] The cloth feeding device is a device used in the textile industry to feed cloth into subsequent processing equipment. It is used to transport cloth. Its main function is to ensure that the cloth can maintain appropriate tension and position when entering the subsequent processing procedures to ensure processing quality. The cloth feeding device usually includes various cloth guide rollers, tension rollers, expansion rollers and other components. They work together to enable the cloth to smoothly and evenly enter the subsequent processing equipment, such as printing machines, setting machines, etc.

[0003] The fabrics in the workshop stacking car are basically in a tension-free, folded and stacked state. If the fabrics are directly put into the machine for finishing, wrinkles and skewness will easily occur, which will inevitably affect the smooth progress of dyeing and finishing and the quality of printing and dyeing products. In order to overcome the above phenomenon, the fabrics must be processed by the cloth feeding device before entering the machine for finishing. The purpose is to: give the fabrics appropriate tension so that the fabrics can enter the machine flatly without wrinkles; guide the fabrics to run in the normal position of the machine to prevent the fabrics from deviating too much to the left and right; make the dust and debris caught in the fabrics fall naturally, or make it easy for the operator to find and remove them in time, to prevent dust and other debris from entering the machine and damaging the rollers or affecting the product quality. In addition, if the fabrics are found to be knotted or not sewn, the machine can be stopped in time to play a buffering role.

[0004] Chinese patent application CN103112744A discloses a fabric feeding device, including a frame, a fabric guide frame, a fabric guide roller, a tensioning mechanism, an adjusting rod, a suction device, a suction adjusting mechanism, a wire separation mechanism and a protective rod. By installing the tensioning mechanism, the suction device and the wire separation mechanism on the fabric feeding machine, the non-woven fabric can be adjusted in tension, the fabric surface can be sucked and the wire separation operation can be performed during the fabric feeding process, so that the fabric surface is clean, flat and has no defects; the tensioning mechanism can be manually adjusted by the adjusting rod, so that the adjustment is more convenient and effective; by installing the suction adjusting mechanism on both sides of the suction device, the distance between the suction device and the fabric surface can be quickly and conveniently adjusted, the operation is simple, and the suction effect is improved; in addition, a protective rod is installed on one side of the frame to ensure the personal safety of workers during operation;

[0005] Chinese Patent Application CN109928243A discloses a fabric feeding structure of a spreading machine, including a frame moving on a spreading platform through wheels and a fabric feeding frame arranged on one side in the length direction of the spreading platform. A spreading motor connected to the wheels is arranged on the frame, and a cloth clamping assembly electrically connected to the spreading motor is arranged on the frame. An air shaft is rotatably arranged at one end of the fabric feeding frame away from the frame. A magnetic powder brake connected to the air shaft and electrically connected to the spreading motor is also arranged on the fabric feeding frame. The fabric roll is fixedly sleeved on the air shaft. Through the settings of the air shaft and the magnetic powder brake, the fabric roll is in a suspended state, and the fabric is kept in a certain tension state during the conveying process, and the remaining amount of unwinding is also greatly reduced. Thus, the probability of wrinkles and creases can be greatly reduced, the scrap rate of the fabric is reduced, and the cost is reduced.

[0006] The above patent application and the prior art also have the following defects:

[0007] On one side of the fabric feeding device, there is often fabric without tension. The fabric is prone to curling, folding, and wrinkling on the conveying rollers. The anti-curling structure in the prior art cannot continuously flatten the fabric, cannot unfold the folded fabric during the flattening process of the fabric, and cannot unfold the fabric with inconsistent folding directions at the edges.

[0008] Therefore, the present application provides a fabric feeding device and a fabric feeding method for mosquito repellent netting fabric to meet the requirements. Summary of the Invention

[0049] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0050] Embodiment 1: Refer to Figures 1 - 13 A fabric feeding device as shown, which includes a base 1 and a plurality of conveyor assemblies 2. The plurality of conveyor assemblies 2 are installed on the base 1 and can drive the fabric to move. A plurality of anti-curling edge assemblies 3 are also provided on the base 1;

[0051] The anti-curling edge assembly 3 includes a rotating shaft 31 and a plurality of pushing units 32. The pushing unit 32 includes a pushing plate 321 and a pushing rod 322. The rotating shaft 31 can drive the pushing plate 321 and the pushing rod 322 to rotate, and the pushing plate 321 is arc-shaped;

[0052] The anti-curling edge assembly 3 further includes a pushing ring 33. The pushing ring 33 is provided with a pushing protrusion. When the pushing rod 322 rotates, it moves circumferentially on the pushing ring 33, and the pushing protrusion is arranged at the position where the rotating shaft 31 contacts the fabric;

[0053] The pushing unit 32 further includes a return spring 323. When the pushing ring 33 moves to the position of the pushing protrusion, it can push the return spring 323 to compress;

[0054] Two edge-suction assemblies 4 are also provided on the base 1. The two edge-suction assemblies 4 are arranged on both sides of the fabric. The edge-suction assembly 4 includes two edge-suction shells 41. The side edge of the fabric is located between the two edge-suction shells 41. A negative pressure can be generated inside the edge-suction shell 41. The edge-suction assembly 4 further includes an adjusting unit 42, and the adjusting unit 42 can adjust the distance between the two edge-suction shells 41.

[0055] The fabric is conveyed on the base 1 through the conveying component 2. The movement of the fabric drives the rotation of the rotating shaft 31. The rotating shaft 31 drives the pushing plate 321 and the pushing rod 322 to rotate. The pushing rod 322 moves circumferentially on the pushing ring 33. When the pushing rod 322 moves circumferentially on the pushing ring 33 to the pushing protrusion, the pushing protrusion squeezes the pushing rod 322 to move. The pushing rod 322 squeezes the return spring 323 to store energy. The pushing rod 322 drives the pushing plate 321 to move. Since the pushing protrusion is arranged at the position where the rotating shaft 31 contacts the fabric, when the pushing rod 322 moves to the position of the pushing protrusion, the pushing plate 321 contacts the fabric, and the pushing plate 321 moves away from the fabric, unfolding the folded part of the fabric edge. Then the fabric continues to move. The two edge suction shells 41 attract the edges of the fabric through negative pressure to prevent the fabric from re-curling until the next conveying component 2. The two conveying components 2 tighten the fabric, so that the flat driving screen fabric will not re-curl during subsequent transmission.

[0056] Through the rotation of the rotating shaft 31, the rotating shaft 31 drives the pushing plate 321 to rotate. When the pushing plate 321 rotates and contacts the fabric, it moves outward from the fabric edge. The pushing plate 321 drives the folded part of the fabric to move, unfolding the folded part of the fabric, which can prevent the fabric from folding at the edge during the transmission process, especially at the initial fabric feeding stage, improving the fabric processing quality and reducing worker intervention. The edge suction component 4 is provided on the two conveying components 2. The edge suction component 4 continuously attracts the fabric edge through negative pressure to prevent the fabric from wrinkling and re-curling until the two conveying components 2 tighten the fabric, so that the tightened flat fabric will not wrinkle and curl during subsequent transmission and processing.

[0058] The rotating shaft 31 drives the rotating rod 35 to rotate. The rotating rod 35 drives the rotating plate 36 to rotate. The rotating plate 36 drives the pushing rod 322 to move circumferentially. When the pushing rod 322 moves to the position of the pushing protrusion on the pushing ring 33, the pushing protrusion squeezes the pushing rod 322 to move. The pushing rod 322 drives the rectangular rod 324 to move. The rectangular rod 324 slides in the rotating plate 36.

The pushing rod 322 drives the pushing plate 321 to move. Since the pushing protrusion is arranged at the contact position between the rotating shaft 31 and the mosquito-repellent netting fabric, when the pushing rod 322 moves to the position of the pushing protrusion, the pushing plate 321 contacts the mosquito-repellent netting fabric, and the pushing plate 321 moves away from the mosquito-repellent netting fabric, unfolding the folded part of the edge of the mosquito-repellent netting fabric;

[0079] The pushing plate 321 continues to rotate, and the return spring 323 drives the pushing plate 321 to reset;

[0080] After that, the mosquito-repellent netting fabric continues to move, and the two edge-suction shells 41 attract the edges of the mosquito-repellent netting fabric through negative pressure to prevent the mosquito-repellent netting fabric from curling again until the next conveying component 2. The two conveying components 2 tighten the mosquito-repellent netting fabric, and the flat driving netting fabric will not curl again during subsequent transmission;

[0081] Among them, the fabric is a plain weave fabric with a width of 208 cm, a warp density of 11 threads per centimeter, a weft density of 14 threads per centimeter. The warp yarn is polyester single-hole yarn, and the 11th steel reed is adopted with a process of staggered distribution of four-piece two-through and two-piece one-through; the weft yarn is alternately sprayed and woven with polyester single-hole yarn and 600 / 96F FDY at a ratio of 1:1. The total number of warp threads is 2280, the reed number is the 11th steel reed, the number of warp threads per reed is 2, the reed width on the loom is 228 cm, and the weft density on the loom is 13.5 picks.

[0082] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
