DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0045] Please refer to 1-8, the preparation method of the antistatic fiber fabric, the preparation method of the antistatic fiber fabric comprises the following steps:

[0046] S1: Open and comb the fibers to ensure parallel arrangement of the fibers;

[0047] S2: stretching, twisting and spinning the fibers to form long and thin yarns;

[0048] S3: Weaving yarn into fabric by plain, twill or satin weaving;

[0049] S4: The formed cloth is rolled onto the outer side of the crossbar 2 through the hook 31 on the rotating beam 3 to form a cloth roll, and the cloth roll is placed in a dyeing vat to be dyed at high temperature;

[0050] S5: calendering, shrinking and waterproofing the dyed fabric;

[0051] S6: Test the elasticity, strength, thickness, fastness, pH value and other data of the fabric and package it.

[0052] The device for preparing antistatic fiber fabric is used to implement the above-mentioned method for preparing antistatic fiber fabric, including a support frame 1 and a cross bar 2, a plurality of rotating beams 3 are fixedly arranged on the cross bar 2, and a plurality of hooks 31 are slidably arranged on the plurality of rotating beams 3; a vertical plate 5 is slidably arranged on the rotating beam 3, and a plurality of hooks 31 are slidably connected with the vertical plate 5, a first spring 32 is arranged between the hook 31 and the vertical plate 5, and the two ends of the first spring 32 are respectively fixedly connected with the hook 31 and the vertical plate 5; it also includes a lifting component, which is used to push the hook 31 in turn to extend it, and fix the hook 31 after the fabric is rolled up; a limiting component, which is used to ensure the stability of the hook 31 during the process of dyeing and moving the fabric by rotating the cross bar 2, and to rotate the cross bar 2 and the rotating beam 3 when the fabric is laid, and during the rotation process, the plurality of hooks on the rotating beam 3 are moved by the lifting component. The first spring 32 is compressed and the hook 31 is retracted to fix the two sides of the cloth on the hook 31. Then, the cross bar 2 and the rotating beam 3 continue to rotate, and the first spring 32 is reset to retract the hook 31, so that the hook 31 cooperates with the rotating beam 3 to clamp and fix the two sides of the cloth, and at the same time, the hook 31 of the next rotating beam 3 is opened to fix the next fixed point of the cloth. With the rotation of the rotating beam 3 and the cross bar 2, the opening and tightening of the hook 31 are completed, which not only facilitates the fixation of the cloth during the cloth rolling process, but also makes the cloth more stable after being rolled and fixed, and makes the cloth more stable during the dyeing process, thereby improving the dyeing quality and efficiency of the cloth. At the same time, after the cloth is rolled, the first spring 32 is compressed by sliding the vertical plate 5, thereby increasing the clamping force of the hook 31 on the cloth, and further improving the stability of the cloth during the dyeing process.

[0053] In an embodiment further provided by the present invention, the lifting assembly includes a lifting block 4, a third inclined surface 41 and a fourth inclined surface 42 are provided on the lifting block 4, a first inclined surface 33 and a second inclined surface 34 are provided on the hook 31, the fourth inclined surface 42 is in contact with the first inclined surface 33, and the third inclined surface 41 is in contact with the second inclined surface 34. During the cloth rolling process, the cross bar 2 and the rotating beam 3 rotate, and the lifting block 4 slides. Under the action of the fourth inclined surface 42 and the first inclined surface 33, the hook 31 is extended to facilitate hanging the cloth on the hook 31, and when the cross bar 2 and the rotating beam 3 continue to rotate, the lifting tube is disengaged from the hook 31, the hook 31 is retracted, and cooperates with the rotating beam 3 to clamp the cloth, thereby improving the stability of the cloth during the rolling process, and disassembling the cloth after dyeing. When the cloth is removed, the cross bar 2 and the rotating beam 3 are rotated in the opposite direction, and the lifting block 4 slides in the opposite direction, and the hook 31 is extended through the abutment between the third inclined surface 41 and the second inclined surface 34, so as to facilitate the removal of the cloth from the hook 31; it should be noted that the lifting block 4 in the present invention, when sliding, the cross bar 2 and the rotating beam 3 rotate one circle, the lifting block 4 slides from the hook 31 position to the next hook 31 position, and the initial position of the lifting block 4 on each rotating beam 3 arranged in a circle, and the distance between the first hook 31 on the rotating beam 3 is increased equidistantly in sequence, so that during the rotation of the cross bar 2 and the rotating beam 3, the hook 31 on the rotating beam 3 will not be extended until each rotating beam 3 rotates to a specified position, which greatly improves the portability of rolling up the cloth.

[0054] Furthermore, a first abutment block 43 is fixedly provided on the lifting block 4, and a second abutment block 51 is fixedly provided on the vertical plate 5, and both the first abutment block 43 and the second abutment block 51 are provided with inclined surfaces, and are in contact with each other through the inclined surfaces. After the cloth is rolled up, the inclined surfaces of the first abutment block 43 and the second abutment block 51 abut against each other, and under the action of the inclined surfaces, the vertical plate 5 slides and squeezes the first spring 32, thereby further improving the clamping stability of the hook 31 on the cloth. It should be noted that the second abutment block 5 on the vertical plate 5 of each rotating beam 3 arranged in a circle 1, and the distance between the outermost hook 31 on the rotating beam 3 is reduced in sequence and at equal intervals, so that after the cloth is rolled up, the vertical plates 5 on each rotating beam 3 can slide simultaneously by the rotation of the horizontal bar 2 with each rotating beam 3, thereby improving the clamping stability of all hooks 31 on the cloth; further, when the cloth is removed, the lifting block 4 slides the first abutment block 43 to disengage from the second abutment block 51. At this time, under the action of the first spring 32, the vertical plate 5 is reset, and when the lifting block 4 extends a single hook 31, it has no effect on the vertical plate 5.

[0055] Furthermore, a second reel 8 is rotatably provided on the rotating beam 3, a second steel wire rope 81 is provided between the second reel 8 and the lifting block 4, and the two ends of the second steel wire rope 81 are respectively fixedly connected to the second reel 8 and the lifting block 4, and are wound around the second reel 8; a volute spring is provided between the second reel 8 and the rotating beam 3, a fixed shaft 6 is rotatably provided on the cross bar 2, a first reel 61 is fixedly provided on the fixed shaft 6, a first steel wire rope 62 is provided between the first reel 61 and the lifting block 4, and the two ends of the first steel wire rope 62 are respectively connected to the second reel 8 and the lifting block 4 The first reel 61 is fixedly connected to the lifting block 4 and is wound around the first reel 61. When the cross bar 2 and the rotating beam 3 rotate, the first steel wire rope 62 on the first reel 61 is loosened. At this time, under the action of the volute spring, the second reel 8 reels the second steel wire rope 81 to make the lifting block 4 slide. When the cross bar 2 and the rotating beam 3 rotate in the opposite direction, the first reel 61 reels the first steel wire rope 62 to pull the lifting block 4 to slide and overcome the action of the volute spring to make the second reel 8 loosen the second steel wire rope 81.

[0056] In an embodiment further provided by the present invention, the limiting assembly includes a tooth block 72 slidably arranged on the fixed shaft 6, a tooth groove 21 is arranged on the cross bar 2, and the tooth block 72 is engaged with the tooth groove 21. When the tooth block 72 is engaged with the tooth groove 21, the fixed shaft 6 and the cross bar 2 rotate synchronously to ensure the stability of the first reel 61, thereby improving the clamping stability of the hook 31 on the cloth, and also avoiding relative rotation between the cross bar 2 and the fixed shaft 6 when the cloth is dyed, thereby causing instability. When the cloth is laid, the tooth block 72 is disengaged from the tooth groove 21, and the cross bar 2 and the rotating beam 3 are supported by the fixed shaft 6, and when the cross bar 2 and the rotating beam 3 rotate, the fixed shaft 6 does not move, so that when the cross bar 2 and the rotating beam 3 are rotated, the first reel 61 completes the winding and loosening of the first steel wire rope 62.

[0057] In the embodiment provided by the present invention, a sliding rod 7 is slidably provided on the fixed shaft 6, a connecting block 73 is provided between the sliding rod 7 and the tooth block 72, and the two ends of the connecting block 73 are rotatably connected to the sliding rod 7 and the tooth block 72 respectively; a second spring 71 is provided between the sliding rod 7 and the fixed shaft 6, and the two ends of the second spring 71 are fixedly connected to the sliding rod 7 and the fixed shaft 6 respectively, a telescopic block 75 is slidably provided on the fixed shaft 6, and a convex block 76 is fixedly provided on the telescopic block 75, and the sliding rod 7 is provided with an inclined groove 74, and the convex block 76 is slidably provided in the inclined groove 74, and when the cloth is pressed When laying, the second spring 71 is in a compressed state, and the sliding rod 7 slides through the cooperation of the protrusion 76 and the inclined groove 74, and the tooth block 72 slides and disengages from the tooth groove 21 through the connecting block 73, so that the cross bar 2 and the rotating beam 3 can rotate without being restricted by the fixed shaft 6. When the cloth is dyed, under the action of the second spring 71, the sliding rod 7 slides and the tooth block 72 is engaged with the tooth groove 21 through the connecting block 73, so that the cross bar 2 and the fixed shaft 6 rotate synchronously. When the second spring 71 is in a normal state, the telescopic block 75 is in an extended state.

[0058] Specifically, a plug-in portion 11 is fixedly provided on the support frame 1, and a plug-in block 63 is fixedly provided on the fixed shaft 6, and the plug-in block 63 is slidably plugged with the plug-in portion 11; the telescopic block 75 abuts against the inner wall of the plug-in portion 11. When the cloth is laid or removed, the plug-in block 63 is plugged with the plug-in portion 11, and the telescopic block 75 abuts against the inner wall of the plug-in portion 11. Under the action of gravity, the telescopic block 75 slides and retracts into the fixed shaft 6. At the same time, through the cooperation of the protrusion 76 and the inclined groove 74, the second spring 71 is compressed to make the sliding rod 7 slide, and the tooth block 72 is separated from the tooth groove 21. When the plug-in block 63 is separated from the plug-in portion 11, under the resetting action of the second spring 71, the sliding rod 7 slides, the telescopic block 75 extends, and the tooth block 72 is engaged with the tooth groove 21.

[0059] The dye vat mentioned in the present invention is used to hold dyes and cooperate with the present invention to dye the cloth. The present invention can arrange transmission devices at both ends of the fixed shaft 6 or the cross bar 2 to cooperate with the dye vat to complete the rotation of the cloth roll during the dyeing process. All of them can be achieved through existing technologies and are common knowledge of technicians in this field, so no further elaboration is made.

[0060] Working principle: in the process of rolling up the cloth, the plug-in block 63 is plugged into the plug-in portion 11, and the cross bar 2 is supported by the support frame 1. At this time, the telescopic block 75 abuts against the inner wall of the plug-in portion 11 and slides into the interior of the fixed shaft 6. Through the cooperation of the protrusion 76 and the inclined groove 74, the sliding rod 7 slides to squeeze the second spring 71, and at the same time, the tooth block 72 slides and disengages from the tooth groove 21 through the connecting rod. Subsequently, the cloth is rolled up, and the cross bar 2 and the rotating beam 3 are rotated, and the fixed shaft 6 and the first reel 61 do not rotate. In the process of rotation of the rotating beam 3, the first steel wire rope 62 of the first reel 61 is relaxed, and under the action of the spiral spring, the second reel 8 reels the second steel wire rope 81 to This makes the lifting block 4 slide, and in the sliding process, the fourth inclined surface 42 contacts the first inclined surface 33, so that the hook 31 slides out and squeezes the first spring 32. When the hook 31 is extended, the cloth is hung on the hook 31. Then the cross bar 2 and the rotating beam 3 continue to rotate, and the hook 31 on the next rotating beam 3 is extended, and the two sides of the cloth are also hung on the extended hooks 31. Moreover, when the hook 31 on the rotating beam 3 is extended, the hook 31 located on the previous rotating beam 3 is separated from the corresponding lifting block 4. At this time, the hook 31 retracts and cooperates with the rotating beam 3 to clamp the cloth, thereby improving the stability of the cloth during and after rolling. Through this operation, multiple rotating beams 3 are used. And the hook 31 on the rotating beam 3 is cooperated to complete the winding of the cloth. After the cloth is rolled up, the first abutment block 43 on the lifting block 4 abuts against the second abutment block 51 on the vertical plate 5. Under the action of the inclined surface, the vertical plate 5 slides to compress the multiple first springs 32. Under the compression of the first springs 32, the hook 31 fixes the cloth more firmly; after the cloth is rolled up, the cross bar 2 is lifted. At this time, under the action of the second spring 71, the sliding rod 7 slides, and the tooth block 72 slides and engages with the tooth groove 21 through the connecting block 73, completing the fixed limit between the fixed shaft 6 and the cross bar 2, so that during the cloth dyeing process, the cross bar 2, the rotating beam 3 and the fixed shaft 6 rotate synchronously, and then Place it in the dye vat to dye the cloth; after completion, place it back on the support frame 1, plug the plug-in block 63 into the plug-in part 11, disengage the tooth block 72 from the tooth groove 21, and make the cross bar 2 and the rotating beam 3 rotate in the opposite direction. At this time, because the first reel 61 does not rotate, during the reverse rotation of the rotating beam 3, the first steel wire rope 62 is wound around the first reel 61, and the second reel 8 relaxes the second steel wire rope 81 under the action of tension, and makes the lifting block 4 slide in the opposite direction. During the sliding process, the hook 31 is extended through the abutment of the third inclined surface 41 and the second inclined surface 34, and the cloth is disengaged from the hook 31, and the cloth is taken off, thus completing the dyeing of the cloth.

[0061] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
