Description

Technical Field

[0001] The present invention relates to the technical field of textiles, and particularly to a cotton feeding adjustment device for textile yarns. Background Art

[0002] In the field of textiles, during the spinning process of a spinning machine for making canvas yarns, the sliver passes through a feeding channel, passes through the holding area composed of a feeding roller and a feeding plate, and is then grabbed by a carding roller for carding and impurity removal. The holding area composed of the feeding plate and the feeding roller needs to apply a certain pressure to the passing sliver to ensure that the sliver is evenly transported to the grabbing range of the high-speed rotating carding roller. Under long-term operation, the distance between the feeding plate and the feeding roller in the holding area will become wider due to the transportation of the sliver, resulting in the sliver being unable to be stably transported to the grabbing range of the carding roller, reducing the carding efficiency of the carding roller.

[0003] Currently, the patent with the application number CN201420300331.2 discloses a cotton feeding adjustment device for canvas spinning. In the existing market, when using the distance adjustment device between the feeding plate and the feeding roller, it is difficult to achieve precise adjustment through the bolt adjustment method, and the tightening force of the nut is limited. After a period of time, it will inevitably become loose, and it is difficult to ensure that the gauge between the feeding roller and the feeding plate remains unchanged. On the other hand, the surface of the feeding plate will inevitably be worn after long-term use. At this time, the distance between the adjusted feeding plate and the feeding roller also changes with the wear, making it difficult to monitor it in real time, and the staff cannot adjust the distance between the two in real time. Therefore, the present invention provides a cotton feeding adjustment device for textile yarns to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a cotton feeding adjustment device for textile yarns. It adopts a combined design of an inner tube and an outer tube structure, and a lubrication mechanism is configured on the outer side of the inner tube to inject lubricating fluid between the inner and outer tubes to reduce friction during operation, thereby increasing the overall service life in effect. At the same time, the detachable inner and outer tubes can be separated after the overall use is scrapped, and the inner tube can be discarded while the outer tube continues to be used, reducing the overall use cost, with obvious practical effects.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A cotton feeding adjustment device for textile yarns, comprising a cotton feeding plate and a cotton feeding roller docked to the cotton feeding plate. Connecting blocks are fixedly connected to both sides of the cotton feeding plate, and fixing plates are symmetrically arranged on both sides of the cotton feeding plate. A horizontal chute connected to the connecting block penetrates through the outer side of the fixing plate. A rotating shaft that movably penetrates the connecting block is rotatably connected in each of the two groups of horizontal chutes. One group of rotating shafts movably penetrates and extends to the back of the fixing plate and is fixedly connected to a large gear disc. A connecting plate is fixedly connected between the two fixing plates. A small gear disc that meshes and drives the large gear disc to rotate is rotatably connected to the outer side of the connecting plate, and a limiting mechanism for clamping and limiting the small gear disc is fixedly installed on the outer side of the connecting plate. An arc-shaped piece is attached to the side of the cotton feeding plate that docks to the cotton feeding roller, and an installation mechanism for adjusting the position of the arc-shaped piece is arranged on the outer side of the cotton feeding plate near the bottom.

[0007] Preferably, outer grooves are provided on the contact surfaces of the upper and lower ends of the connecting block with the inner wall of the chute. Ball bearings are embedded in the outer grooves, and limiting grooves that are in rolling contact with the ball bearings are horizontally arranged on the upper and lower groove walls of the chute.

[0008] Preferably, the diameter of the ball bearing is larger than the diameter of the notch of the outer groove.

[0009] Preferably, the limiting mechanism includes a fixed seat fixedly connected to the outer side of the connecting plate. Two groups of symmetrically arranged movable rods are movably arranged on the outer side of the fixed seat, and a clamp that docks to the outer side of the small gear disc is movably arranged on the inner wall of the movable rod.

[0010] Preferably, a threaded rod horizontally penetrates through the fixed seat, and the outer end of the threaded rod is rotatably connected to a movable block. The outer side of the movable block is connected to the inner wall of the movable rod through an adjusting rod.

[0011] Preferably, the fixed seat and the movable rod, the movable rod and the clamp, and the adjusting rod and the movable block and the movable rod are all rotatably connected through rotating shafts.

[0012] Preferably, a friction layer and a tooth layer are sequentially arranged on the outer wall of the small gear disc from the inside to the outside. The tooth layer on the outer side of the small gear disc meshes with the large gear disc, and the friction layer on the outer side of the small gear disc is in frictional contact with the clamp.

[0013] Preferably, the installation mechanism includes an inner groove arranged on the outer side of the cotton feeding plate. A threaded shaft is movably inserted into the inner groove, and a connecting rod is fixedly connected to the outer end of the threaded shaft. The connecting rod is fixedly connected to the bottom of the arc-shaped piece.

[0014] Preferably, a rotating sleeve is rotatably connected to the outer side of the inner groove, and the rotating sleeve is threadedly sleeved on the outer side of the threaded shaft.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In the present invention, the feed plate is arranged between two fixing plates, and the distance between the feed plate and the feed roller is adjusted by the principle of screw drive. On this basis, a large gear disk with a relatively large diameter is fixedly arranged at the outer end of the "screw" for transmission, and is driven by meshing with a small gear disk with a smaller outer diameter, so that the distance between the feed plate and the feed roller can be finely adjusted. The adjusted small gear disk can be limited and fixed by means of an external limiting mechanism, so as to limit the distance between the two after adjustment, avoid structural loosening affecting the stability of the feed plate, and stabilize the distance between the feed plate and the feed roller. In addition, the present invention also provides a fitting arc-shaped piece on the outside of the feed plate, and the pressure sensor at the bottom of the arc-shaped piece contacts the feed plate. After the surface of the arc-shaped piece is slightly worn for a long time, the buzzer can be alerted in time through the pressure change of the pressure sensor, which is convenient for the staff to adjust again or replace the arc-shaped piece to ensure the normal use of the whole.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the 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 of the embodiments.

[0030] A cotton feeding adjustment device for textile yarns, comprising a cotton feeding plate 1 and a cotton feeding roller 2 docked to the cotton feeding plate 1. Connecting blocks 3 are fixedly connected to both sides of the cotton feeding plate 1, and fixing plates 4 are symmetrically arranged on both sides of the cotton feeding plate 1. A horizontal sliding groove 5 connected to the connecting block 3 is penetrated through the outside of the fixing plate 4. A rotating shaft 7 that movably penetrates the connecting block 3 is rotatably connected in both groups of horizontal sliding grooves 5. A thread is arranged on the outside of one group of rotating shafts 7, and the connecting block 3 is driven by the thread on the outside of this group of rotating shafts 7. This group of rotating shafts 7 movably penetrates and extends to the fixing plate 4 and is fixedly connected to a large gear disc 8. A connecting plate 6 is fixedly connected between the two fixing plates 4. A small gear disc 9 that meshes and drives the large gear disc 8 to rotate is rotatably connected to the outside of the connecting plate 6, and a limiting mechanism 10 for clamping and limiting the small gear disc 9 is fixedly installed on the outside of the connecting plate 6. An arc-shaped piece 12 is attached to the side of the cotton feeding plate 1 docked to the cotton feeding roller 2, and an installation mechanism 11 for adjusting the position of the arc-shaped piece 12 is arranged on the outside of the cotton feeding plate 1 near the bottom.

[0031] When the present invention is in use, the yarn passes between the arc-shaped piece 12 outside the cotton feeding plate 1 and the cotton feeding roller 2. When the distance needs to be adjusted, the small gear disc 9 meshes and drives the large gear disc 8. The large gear disc 8 drives a group of rotating shafts 7 to rotate and drives the connecting block 3 by the thread on the outside, so that the connecting block 3 is limited and slides in the outer groove 301 and drives the cotton feeding plate 1 to move in position to adjust the distance from the cotton feeding roller 2. After the adjustment, the limiting mechanism 10 is used to frictionally clamp the small gear disc 9 to fix the adjusted distance. And subsequently, the arc-shaped piece 12 can be disassembled through the installation mechanism 11, which is convenient for the overall long-term use.

[0032] Wherein, outer grooves 301 are arranged on the contact surfaces of the upper and lower ends of the connecting block 3 with the inner wall of the sliding groove 5. Ball bearings 302 are embedded in the outer grooves 301. Limiting grooves 303 that are in rolling contact with the ball bearings 302 are horizontally arranged on the upper and lower groove walls of the sliding groove 5. The diameter of the ball bearings 302 is larger than the notch diameter of the outer groove 301. When the cotton feeding plate 1 is adjusted in position, the outer connecting block 3 is slidably limited by the outer groove 301, and the limiting sliding between the ball bearings 302 and the limiting grooves 303 can reduce the overall moving friction and facilitate the smooth sliding for adjustment.

[0033] The limiting mechanism 10 includes a fixing seat 1001 fixedly connected to the outside of the connecting plate 6, two sets of symmetrical movable rods 1002 are movably arranged on the outside of the fixing seat 1001, and a clamp 1003 connected to the outside of the small toothed plate 9 is movably arranged on the inner wall of the movable rod 1002, a threaded rod 1004 is arranged through the transverse thread in the fixing seat 1001, and a movable block 1005 is rotatably connected to the outer end of the threaded rod 1004, and the outer side of the movable block 1005 is adjusted by the adjusting rod 1006. The inner wall of the movable rod 1002 is connected, and the fixed seat 1001 and the movable rod 1002, the movable rod 1002 and the clamp 1003, and the adjusting rod 1006 and the movable block 1005 and the movable rod 1002 are all rotatably connected through the rotating shaft 1007. The outer wall of the small toothed disc 9 is provided with a friction layer and a tooth layer in sequence from the inside to the outside. The tooth layer at the outer end of the small toothed disc 9 is meshed with the large toothed disc 8, and the friction layer on the outer side of the small toothed disc 9 is in friction contact with the clamp 1003. The threaded rod 1004 is threadedly rotated on the outer side of the fixed seat 1001 and the movable block 1005 is pushed to move through the bearing at the outer end. The movable block 1005 adjusts the angle of the movable rod 1102 through the outer adjusting rod 1006. The two sets of clamps 1003 on the inner wall of the movable rod 1002 are used to make secondary friction contact with the friction layer of the small toothed disc 9 after adjustment, thereby preventing the small toothed disc 9 from rotating and ensuring its stability after adjustment to the large toothed disc 8, that is, reinforcing the distance between the cotton feeding plate 1 and the cotton feeding roller 2 after adjustment.

[0034] Among them, the mounting mechanism 11 includes an inner groove 1101 arranged on the outer side of the cotton feeding plate 1, a threaded shaft 1102 is movably inserted in the inner groove 1101, and the outer end of the threaded shaft 1102 is fixedly connected to a connecting rod 1103, and the connecting rod 1103 is fixedly connected to the bottom of the arc-shaped piece 12, and the outer side of the inner groove 1101 is rotatably connected to a rotating sleeve 1104, and the rotating sleeve 1104 is threadedly sleeved on the outer side of the threaded shaft 1102, and a rectangular rod 1105 with a rectangular cross-section is fixedly connected to the inner wall of the inner groove 1101, and the rectangular rod 1105 slides through and is connected to the inner end of the threaded shaft 1102. During use, by rotating the rotating sleeve 1104, the threaded shaft 1102 is driven by the rotating sleeve 1104 thread, and the threaded shaft 1102 is extended and retracted in the inner groove 1101 between the inner side of the threaded shaft 1102 and the limit of the rectangular rod 1105, so as to facilitate the detachable installation of the arc piece 12 to fit the outer side of the cotton feeding plate 1. During actual use, the yarn is located on the outer side of the arc piece 12 and between the cotton feeding roller 2, and the arc piece 12 can be replaced and used through the above structure after long-term use.

[0035] Among them, a pressure sensor 13 is arranged on the contact surface bracket between the bottom of the arc-shaped piece 12 and the surface of the feeding plate 1, a buzzer 14 is arranged outside the fixing plate 4, and the buzzer 14 is electrically connected to the pressure sensor 13 through a PLC controller. With long-term spinning use, the surface of the arc-shaped piece 12 will be worn, and then the distance between the arc-shaped piece 12 and the feeding roller 2 will also increase. At this time, the pressure generated by the yarn on the arc-shaped piece 12 when passing between the arc-shaped piece 12 and the feeding roller 2 will also decrease. At this time, the pressure sensor 13 will detect the pressure decrease and drive the buzzer 14 to give an alarm through the PLC controller, so as to adjust the staff. The staff can rotate the small gear disk 9 and cooperate with the above transmission structure to finely adjust the distance between the feeding plate 1 and the feeding roller 2 again.

[0036] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and shall be included in the protection scope of the present invention. In addition, it should be understood that the terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.
