Detailed Description

The embodiment of the invention provides a device and a method for improving the water staining fastness of woven fabric, and relates to a device and a method for improving the water staining fastness of woven fabric, which are used for the woven fabric 6, as shown in figures 1-8. The device comprises a box body 1, a plurality of front flattening mechanisms 2, a traction wheel 3, a bearing plate 4 and a back flattening mechanism 5. A plurality of front smoothing mechanisms 2 are fixedly arranged on the top of the inner wall of the box body 1. The traction wheel 3 is positioned below the front flattening mechanism 2, and the traction wheel 3 is hinged with the inner wall of the box body 1. The traction wheel 3 is used for driving the woven fabric 6 to move forwards. The bearing plate 4 is located below the traction wheel 3, and the end of the bearing plate 4 is aligned with the traction wheel 3. The bearing plate 4 is welded with the inner wall of the box body 1. The front side of the woven fabric is smoothed by a front side smoothing mechanism 2.

With reference to fig. 2, the back-side smoothing mechanism 5 is symmetrically and fixedly installed at one end of the bearing plate 4. The woven fabric 6 sequentially passes through the front smoothing mechanism 2, the traction wheel 3, the back smoothing mechanism 5 and the receiving plate 4 along the fabric moving direction. The back-side leveling mechanism 5 includes a bracket 21, a roller 22, a leveling assembly, and a lifting assembly. The upper end of the bracket 21 is fixedly connected with the top of the inner wall of the box body 1. The roller 22 is hinged below the bracket 21. The smoothing assembly is located between the bracket 21 and the roller 22. The fabric 6 passes around the roller, and the front surface of the fabric 6 is contacted with the smoothing component. When the woven fabric 6 passes through the rolling shaft 22, the smoothing assembly is unfolded towards two sides to smooth the woven fabric 6, the lifting assembly is located on the support 21, and the lifting assembly is used for controlling the smoothing assembly to reset. The turning of the traction wheel 3 is slow, so that woven fabric is smoothed conveniently, but the specific rotating speed of the traction wheel 3 needs to be adjusted according to actual conditions.

Accept the top of board 4 and be equipped with the space of placing wet lifting agent sprinkler that rubs, because this scheme does not make improvement innovation to wet lifting agent sprinkler that rubs, consequently wet lifting agent sprinkler adopts prior art, and consequently concrete structure, relation of connection are the same with prior art and do not do detailed description.

With reference to fig. 3 and 4, the leveling assembly includes a first leveling plate 23, a second leveling plate 24, a push rod 26 and a telescopic rod 27. A spreader plate 23 is located between the bracket 21 and the roller 22. The first flattening plate 23 is spatially vertical to the roller 22, and the hinged end of the first flattening plate 23 is hinged with the lifting assembly. The push rod 26 is located above the first leveling plate 23, the sliding groove 25 is formed in the bottom of the support 21, and the push rod 26 is welded in the sliding groove 25. Since the slide groove 25 is parallel to the roller 22, the push rod 26 is parallel to the roller 22. The bottom of the movable end of the push rod 26 is welded with the telescopic rod 27. The first smoothing plate 23 is provided with a sliding groove 231 along the length direction of the first smoothing plate, and the lower end of the telescopic rod 27 is in sliding fit with the first smoothing plate 23 through the sliding groove 231. When the telescopic rod 21 is in operation, the movable end of the push rod 21 drives the telescopic rod 27 to move when the push rod 21 stretches. Because the hinged end of the first strike plate 23 is immovable but rotatable, the first strike plate 23 makes a circular motion around the hinged end.

As can be seen from fig. 5 and 6, the second smoothing plate 24 is located on one side of the first smoothing plate 23, and the hinged end of the second smoothing plate 24 is hinged to the lifting assembly. The hinge ends of the first smoothing plate 23 and the second smoothing plate 24 are provided with tooth grooves 28, and the hinge ends of the second smoothing plate 24 are meshed with the hinge end of the first smoothing plate 23. The first smoothing plate 23 and the second smoothing plate 24 perform circumferential telemechanical movement simultaneously, so that the effect of smoothing the woven fabric is achieved. During operation, the push rod 21 drives the telescopic rod 27 to move, so that the first smoothing plate 23 makes circular motion, and the first smoothing plate 23 is hinged to one end of the second smoothing plate 24. The first flattening plate 23 drives the second flattening plate 24, so that the second flattening plate 24 makes circular motion opposite to the direction of the first flattening plate 23, and the whole flattening assembly is unfolded. When the push rod 26 extends to the longest length, the movable range of the stroking plate reaches the maximum value and touches the bracket 21, and then the lifting assembly is reset for one period. The wrinkles on the front surface of the fabric are smoothed out through a plurality of cycles.

Because the lifting assembly is provided, when the push rod 26 contracts the two smoothing plates to close each other, in order to avoid wrinkles generated in the fabric during the closing process, the two smoothing plates need to be lifted up before closing. The lifting assembly comprises two shaft rods 7 and a cylinder 8, and the cylinder 8 is welded on a bracket 21. The expansion end of cylinder 8 welds with two axostylus axostyles 7 respectively, and two axostylus axostyles 7 all run through support 21 and extend to support 21 below, and one of them axostylus axostyle 7 is articulated with pacifying dull and stereotyped 23 articulated end, and another axostylus axostyle 7 transmission end is articulated with pacifying two 24 articulated ends of board. The motor 52 is rotated towards the edge of the fabric 6. During operation, after the push rod 26 extends to the longest length, the cylinder 8 drives the shaft lever 7 to ascend, and the shaft lever 7 drives the stroking plate to ascend. The push rod 26 is then retracted to bring the two plates together towards the middle.

As can be seen from the above, since the leveling plate needs to move up and down, the movable end of the push rod 26 is a telescopic rod in sliding fit with the first leveling plate 23.

As can be seen from the attached figures 2 and 3, the upper end of the bracket 21 penetrates through the inner wall of the box body 1 and extends to the box body 1, the upper end of the bracket 21 is provided with threads, and the upper end of the bracket 21 is connected with a nut 29 in a threaded manner. The bracket 21 is fixed on the top of the inner wall of the box body 1 by adopting a thread fixing mode. The support 21 is welded with the single chip microcomputer 9, and the model of the single chip microcomputer 9 is stm32f407zgt 6. The single chip microcomputer 9 is electrically connected with the push rod 26 and the air cylinder 8 through a lead, and the single chip microcomputer 9 is used for controlling the push rod 26 and the air cylinder 8 to work. The push rod 26 is a common electric push rod with the model of LAP22 and the model of an air cylinder of MHL 2-10D. Since the single chip microcomputer 9, the push rod 26 and the air cylinder 8 are all in the prior art, the specific structure and the connection mode are the same as those in the prior art and are not described in detail.

The back smoothing mechanism 5 is arranged, the wrinkles of the woven cloth have another condition that the edges of the woven cloth are turned upwards, the front smoothing mechanism 2 cannot smooth the wrinkles of the woven cloth, and therefore the back smoothing mechanism which is used for smoothing the back of the edges of the woven cloth is arranged.

The two gears 53 are drivingly connected by a chain 54. A plurality of smoothing hooks 55 are welded to the chain 54 at equal intervals, and the smoothing hooks 55 are used for smoothing wrinkles on the reverse edge of the fabric 6. When the fabric edge flattening device works, the motor 52 drives the gear 53 to rotate, the chain 54 is driven to rotate, and the flattening hook 55 pushes out the downward-turned wrinkles of the fabric edges because the motor 52 rotates towards the fabric edges.
