Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a carding machine for cotton yarn production. Background Art

[0002] The carding machine is mainly used to remove impurities and comb cotton fibers, combing the curled cotton fibers into a stretched and fluffy state. During operation, the carding machine can also remove impurities such as cotton seeds and dead leaves mixed in the cotton fibers.

[0003] Before the carding machine combs the cotton, the staff needs to tear and loosen the cotton in a ball and finally lay it flat on the feeding board. The feeding board is actually a conveyor belt, which can input the cotton to the entrance of the carding machine. Finally, the cotton roller at the entrance of the carding machine will transport the cotton to the inside of the carding machine for combing.

[0004] The purpose of tearing the cotton loose and spreading it on the cotton feeding board is to prevent the cotton from piling up and affecting the cotton conveying by the cotton rollers. Moreover, spreading the cotton on the cotton feeding board in advance can facilitate the combing of the cotton by the combing rollers and combing plates inside the cotton carding machine, thereby improving the efficiency of cotton combing. However, the initial spreading of the cotton still requires the staff to tear and spread it manually, which is a time-consuming process. If the cotton is relatively moist, the moisture will increase the toughness of the cotton, making it more laborious for the staff to pull the cotton into small balls and spread them flat.

[0036] The disengagement component includes a plurality of straight grooves 29 which are arranged on the upper end surface of the feed cylinder 7 and are distributed in a straight line and at equal intervals, and each straight groove 29 is respectively located between two adjacent limiting sleeves 18, and a positioning column 9 is fixedly mounted on the upper side of the two edge guards 1, and a limiting column cylinder 11 is fixedly sleeved on the outer surface of the positioning column 9, and a limiting disk 10 is fixedly arranged on both end surfaces of the limiting column cylinder 11, and a rotating cylinder 12 is rotatably sleeved between the two limiting disks 10, and a plurality of groups of cotton disengaging needles 16 which are distributed in a straight line and at equal intervals are assembled inside the rotating cylinder 12, and each group of cotton disengaging needles 16 The number of the cotton picking needles 16 is at least two and they are equidistantly distributed around the circumference. The cotton picking needle 16 radially slides through the rotating drum 12. A dome piece is fixedly provided at one end of the cotton picking needle 16 extending into the interior of the rotating drum 12, and a first spring 17 is fixedly provided between an end surface of the dome piece away from the axis of the rotating drum 12 and the inner wall of the rotating drum 12. The cotton picking needle 16 is in sliding contact with the straight groove 29. A driving member is also provided on the outside of the rotating drum 12. When the cotton picking needle 16 slides in the straight groove 29, the cotton stuck between two adjacent limit needles 22 can be torn, thereby achieving a dispersing effect.

[0037] The driving member includes a gear differential 26 fixedly mounted on the end of the edge guard plate 1 away from the cotton roller 5, and a third gear 27 is fixedly sleeved on the output end of the gear differential 26. A plurality of teeth 28 equidistantly distributed around the circumference are fixedly arranged on the outer surface of the end of the drum 12, and the third gear 27 is meshed with the teeth 28. The end of a first transmission roller 3 away from the cotton roller 5 and the input end of the gear differential 26 are assembled through a synchronous gear and a synchronous toothed belt transmission. The gear differential 26 can drive the drum 12 to rotate by touching the first transmission roller 3 and meshing the third gear 27 with the teeth 28.

[0038] The limiting cylinder 11 includes a small arc portion 30, a large arc portion 31, an arc surface transition portion 32 and a straight edge portion 33. The arc surface transition portion 32 is located between the small arc portion 30 and the large arc portion 31. The straight edge portion 33 and the arc surface transition portion 32 are oppositely distributed, and the straight edge portion 33 is radially distributed inside the rotating drum 12. When the rotating drum 12 rotates counterclockwise with the cotton picking needle 16, the cotton picking needle 16 contacts the small arc portion 30, the arc surface transition portion 32, the large arc portion 31 and the straight edge portion 33 respectively, so that the position state of the cotton picking needle 16 will change.

[0039] The adjusting member includes a rack 25 that slides through the edge guard plate 1, one end of which is fixedly provided with a hollow cylinder 34, and the lower end surface of the hollow cylinder 34 is slidably fitted with the upper end surface of the edge guard plate 1, and the upper end surface of the edge guard plate 1 is provided with two positioning holes 38, and a movable disk 35 is slidably mounted inside the positioning holes 38, and a positioning rod 37 that slides through the hollow cylinder 34 is fixedly provided at the bottom of the movable disk 35, and the positioning rod 37 is slidably mounted with the positioning hole 38, and a second spring 36 is fixedly provided between the top of the movable disk 35 and the hollow cylinder 34, and the hollow cylinder 34 is provided with a second spring 36.

The lower end surface of each connecting rod 19 is fixedly sleeved with a second gear 24, and the second gear 24 is meshed with the rack 25. When the two movable plates 39 are pressed, the movable disk 35 can be lifted up by the tilting piece 40, thereby separating the positioning rod 37 from the positioning hole 38.

[0040] Working principle: the staff can use a stick-shaped tool to transport the cotton to be processed into the inside of the feed barrel 7 through the flaring barrel 8, or install a feeding structure commonly used in the prior art on the flaring barrel 8 frame to automatically transport the cotton in the flaring barrel 8 toward the inside of the feed barrel 7. Since the feed barrel 7 is close to one end of the cotton roller 5, it is limited by a plurality of limiting sleeves 18 and limiting needles 22 extending from the inside, so that the cotton cannot pass through the feed barrel 7 directly and can only be stopped by the limiting sleeves 18 and limiting needles 22. Due to the driving action of the motor, the first transmission roller 3 drives the first conveyor belt 4 to run continuously clockwise, and the action of the synchronous gear and the synchronous toothed belt can trigger the gear differential 26, and the gear differential 26 can drive the rotating drum 12 to rotate counterclockwise through the meshing of the third gear 27 and the teeth 28;

[0041] See attached Figure 7As shown, when the drum 12 rotates counterclockwise with a plurality of cotton-picking needles 16, the dome sheet at the end of the cotton-picking needle 16 will contact the small arc portion 30, the arc transition portion 32, and the large arc portion 31 in sequence, that is, when the cotton-picking needle 16 is in the state inside the drum 12, it gradually extends out, and in the process of extending, it will also move to the inside of the straight groove 29, tearing out a part of the cotton stuck between two adjacent limiting sleeves 18. Since the cotton-picking needle 16 and the straight edge portion 33 are radially distributed with the drum 12, when the dome sheet is about to contact the straight edge portion 33, under the action of the compressed first spring 17, the cotton-picking needle 16 will directly elastically reset and contact the small arc portion 30, and the cotton hanging on the surface of the cotton-picking needle 16 will also directly fall onto the first conveyor belt 4;

[0042] Therefore, by the reciprocating rotation of the rotating drum 12 with the plurality of cotton removing needles 16, the cotton accumulated inside the feed drum 7 can be torn out piece by piece by the cotton removing needles 16, thereby dividing and dispersing the cotton, thereby replacing the manual cotton splitting process by the staff.

[0043] When cotton is not fed into the net feed tube 7 and the amount of cotton in the feed tube 7 gradually decreases, the staff can adjust the position of the rack 25 to retract the limit pin 22 into the limit sleeve 18. The operation method is:

[0044] The staff can pinch the two movable plates 39 to swing the movable plates 39 toward the inside of the hollow cylinder 34, and move the movable disk 35 upward through the lift plate 40. At this time, the positioning rod 37 is separated from the positioning hole 38, and the rack 25 can be moved until the positioning rod 37 is inserted into the inside of the other positioning hole 38 under the action of the compressed second spring 36. The spacing between the two positioning holes 38 allows the rack 25 to be displaced a short distance, and its displacement allows the rack 25 to drive the second gear 24 to rotate ninety degrees. Since the limit pin 22 is restricted by the limit sleeve 18, when the connecting rod 19 rotates ninety degrees with the elliptical disk 20, the limit pin 22 can be retracted to the inside of the limit sleeve 18, and no longer hinders a small amount of cotton. At this time, a small amount of cotton can be directly moved to the upper surface of the first conveyor belt 4 under the action of the cotton-moving needle 16.

[0045] Example 2: Please refer to Figure 1 and Figure 2This embodiment is a further explanation of the first embodiment. The auxiliary feeding unit includes three second transmission rollers 13 rotatably mounted between two edge guard plates 1. The three second transmission rollers 13 are all located above the first conveyor belt 4, and a second conveyor belt 14 is transmission-assembled between the outer surfaces of the three second transmission rollers 13. The ends of one of the first transmission rollers 3 and the second transmission roller 13 close to the cotton roller 5 are fixedly mounted with a first gear 15, and the two first gears 15 are meshed with each other. Through the cooperation of the two first gears 15, the second conveyor belt 14 can be synchronously transmitted in the reverse direction with the first conveyor belt 4.

[0046] The cross section of the second conveyor belt 14 is an obtuse triangle shape, the bottom surface of the second conveyor belt 14 is parallel to the upper end surface of the first conveyor belt 4, and the raised edge of the second conveyor belt 14 faces the feed barrel 7. The purpose of the raised edge facing the feed barrel 7 is to suppress and move the cotton just separated.

[0047] The side of the second conveyor belt 14 away from the feed cylinder 7 is spaced 20-50 mm from the cotton roller 5. The end of the second conveyor belt 14 is brought close to the cotton roller 5 so that the cotton roller 5 can more smoothly convey the cotton into the carding machine.

[0048] In the present embodiment, when the cotton removing needle 16 is about to touch the surface of the second conveyor belt 14 while following the rotation of the drum 12, it will directly retract into the inside of the drum 12, i.e. no collision will occur. Moreover, through the guidance of the second conveyor belt 14 and the compression of the fluffy cotton, the evenly dispersed cotton can be stably moved toward the direction of the cotton roller 5, and finally the cotton is transported to the inside of the cotton carding machine for combing through the cotton roller 5.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
