Description

Technical Field

[0001] The invention relates to the field of textile equipment, in particular to a twist-free yarn feeding mechanism. Background Art

[0002] The textile industry processes natural and chemical fibers into various yarns, threads, tapes, fabrics, and dyed and finished products. Based on the type of textile produced, it can be categorized into the cotton textile industry, linen textile industry, wool textile industry, silk textile industry, and chemical fiber textile industry. Based on the production process, it can be divided into the spinning industry, weaving industry, printing and dyeing industry, knitting industry, and textile reproduction industry.

[0003] With the development of the times and technology, the textile industry has also developed rapidly at this stage. Among them, textile technology and textile equipment have developed the fastest. The use of more complete textile technology combined with more modern textile equipment can not only effectively reduce the difficulty of textile production, but also improve the output and quality of textile production. One of the most representative technological equipment in the textile industry is the texturizing machine. By using the texturizing machine, untwisted yarns such as polyester and polypropylene can be processed into elastic yarns with medium elasticity and low elasticity through false twist deformation, so that the formed elastic yarns meet the needs of textile production and greatly improve the performance of the formed elastic yarns.

[0004] During use, traditional texturing machines need to feed untwisted yarns such as polyester and polypropylene. Due to the lack of leads and guides for the untwisted yarns during the feeding process, if a large number of untwisted yarns need to be fed at the same time, feeding blockage may occur. That is, during the feeding process, a large number of untwisted yarns may become entangled or knotted under the action of wind or machine vibration, thereby causing feeding blockage of the texturing machine.

[0064] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0066] The fixed base 9 is arranged in a horizontal state; the base mounting mechanism 1 is arranged in a horizontal state on the fixed base 9; a number of single-layer brackets 11, two of which are fixedly arranged at the top ends of the fixed base 9 and parallel to the axis of the base mounting mechanism 1, and the remaining single-layer brackets 11 can be stacked in sequence to form multi-layer brackets, one of the multi-layer brackets is provided with a wire drum material rack assembly 10, then the multi-layer bracket is a wire drum material rack, and the other multi-layer bracket is provided with an outlet assembly 41, then the multi-layer bracket is an outlet rack; the wire drum material rack and the outlet rack have the same number of layers; the wire drum material rack assembly 10 includes a number of double-position racks 20 fixedly arranged in a horizontal state on each layer of the single-layer bracket 11 and arranged at equal intervals along the width side direction parallel to the fixed base 9, and a pair of vertical pay-off mechanisms 23 are fixedly provided in the middle of each double-position rack 20, and the plane positions of the two pay-off mechanisms 23 are centrally symmetrical, and the center of symmetry is the center point of the double-position rack 20, and each pay-off mechanism 23 includes a locking device The locking device 24 and the feeding shaft 36 are fixedly arranged in the middle of the wire-releasing mechanism 23. The top of the locking device 24 is fixedly provided with a wire-leading ring 30. The wire-leading ring 30 is parallel to the width direction of the fixed base 9. The wire-out assembly 41 includes a plurality of stoppers 42 fixedly arranged on each single-layer bracket 11 in a vertical state and arranged at equal intervals along the width direction parallel to the fixed base 9. Each stopper 42 includes a lower wire seat 43 and an upper wire seat 45. And a lifting locking mechanism 46, the lifting locking mechanism 46 is fixedly arranged at the bottom of the fixed end of the single-layer bracket 11, and the upper wire seat 45 is fixedly arranged in a horizontal state on the lifting output end of the lifting locking mechanism 46, and the bottom of the upper wire seat 45 is formed with a pair of semicircular through holes 44 parallel to the length side direction of the fixed base 9, and the top of the supporting end of the single-layer bracket 11 is provided with a lower wire seat 43, and the top of the lower wire seat 43 is formed with a pair of semicircular through holes 44 for receiving the semicircular through holes 44 at the bottom of the upper wire seat 45.

[0067] Before starting loading, install the fixed base 9 of the loading mechanism on the machine through the base mounting mechanism 1, install several layers of single-layer brackets 11 on the fixed base 9 according to the loading requirements, open the locking device 24 on the wire-releasing mechanism 23, release the loading shaft 36, install the wire bobbin on the loading shaft 36, and then use the locking device 24 to lock the loading shaft 36.

[0068] After completing the installation of all the wire bobbins, the wire on the wire bobbin of the wire-releasing mechanism 23 away from the center of the fixed base 9 is passed through the wire lead ring 30 to prevent the wire bobbin from being blocked during loading. After raising the upper wire seat 45 using the lifting and locking mechanism 46 on the limiter 42, the wires drawn out from the two wire bobbins on the double-position material rack 20 are respectively placed into a pair of semicircular through holes 44 of the lower wire seat 43, and then the upper wire seat 45 is lowered to the specified position using the lifting and locking mechanism 46. The loading process of the wire is limited by the closing of the lower wire seat 43 and the upper wire seat 45, thereby realizing the anti-blocking function of the feeding mechanism.

[0069] In order to achieve the effect that the lifting output end of the lifting locking mechanism 46 drives the thread feeder 45 to automatically lock and stop moving when it rises and falls to a specified position, the following features are specifically set:

[0070] The lifting and locking mechanism 46 includes: a shell 47, which is fixedly arranged at the bottom of the fixed end of the single-layer bracket 11, and the top and bottom of the inner side of the shell 47 are respectively formed with a first fixed seat 49 and a second fixed seat 50 in a horizontal state; a rotating dial 51, which is in a vertical state, and the bottom of the rotating dial 51 is axially connected to the middle part of the inner side of the shell 47, and the top center position of the rotating dial 51 is formed with a knob 52 extending to the outside of the shell 47, and the lower half of the rotating dial 51 is formed with a short tilting rod 53 perpendicular to the extension direction of the knob 52 and extending outward, and the upper half of the rotating dial 51 is formed with a long tilting rod 54 perpendicular to the extension direction of the knob 52 and the short tilting rod 53 and extending outward; a third spring 59, which is in a vertical state, and the top end of the third spring 59 is fixedly connected to the first fixed seat 49; a fourth spring 63, which is in a horizontal state, and one end of the fourth spring 63 is fixed It is connected to one side of the second fixed seat 50 close to the third spring 59; the wedge block 60 is in a vertical state, the bottom axis of the top of the wedge block 60 is connected to the inner side of the shell 47, and one side of the middle part of the wedge block 60 is fixedly connected to the other end of the above-mentioned fourth spring 63, and the top of the wedge block 60 is formed with an unlocking rod 61 extending toward the rotating dial 51 for colliding with the tip of the short cocking rod 53, and the bottom of the wedge block 60 is formed with a stop block 62; the movable snap bar 55 is in a vertical state, the top of the movable snap bar 55 is fixedly connected to the bottom end of the third spring 59, the height of the movable snap bar 55 is equal to the height of the rotating dial 51, and the upper half of the side surface of the top of the movable snap bar 55 toward the rotating dial 51 is formed with a first snap 57 for colliding with the tip of the long cocking rod 54, and the upper half of the side surface of the middle part of the movable snap bar 55 toward the rotating dial 51 is formed with a second snap 58 for colliding with the stop block 62.

[0071] The knob 52 outside the rotating housing 47 drives the rotating dial 51 to rotate clockwise in the housing 47. Because the relative height of the long tilting rod 54 in the upper half of the rotating dial 51 is higher than the height of the wedge block 60, the long tilting rod 54 cannot collide with the unlocking rod 61. The long tilting rod 54 that continues to rotate collides with the first buckle 57 on the movable buckle bar 55, driving the movable buckle bar 55 to move upward as a whole. During the rising process of the movable buckle bar 55, the second buckle 58 will move above the stop block 62. When the movable buckle bar 55 rises to a certain height, the collision between the long tilting rod 54 and the first buckle 57 ends. At this time, the movable buckle bar 55 will move downward under the action of the third spring 59, but the second buckle 58 will collide with the stop block 62, resulting in the movable buckle bar 55 being unable to descend. This process is the locking effect of the lifting output end driving the upper wire seat 45 after rising.

[0072] Continue to rotate the knob 52, and the short cocking rod 53 in the lower half of the rotating dial 51 collides with the unlocking rod 61, driving the entire wedge block 60 to rotate counterclockwise with the top as the center. After rotating to a certain position, the stop block 62 will be misaligned with the second buckle 58, thereby ending the collision. The movable buckle bar 55 will continue to descend to the specified position under the action of the third spring 59, and end the movement after the upper line seat 45 contacts the lower line seat 43. After the short cocking rod 53 and the unlocking rod 61 end the collision, the wedge block 60 will rotate clockwise under the action of the fourth spring 63, so that the stop block 62 returns to the position close to the movable buckle bar 55. This process is the locking effect of the upper line seat 45 driven by the lifting output end after it descends.

[0073] In order to achieve the effect that the movable buckle strip 55 can move up and down in a specified area, the following features are specifically set:

[0074] A strip-shaped limiting block 48 is formed on the inner side of the housing 47 , and a strip-shaped through groove 56 is formed in the middle of the movable buckle strip 55 for the strip-shaped limiting block 48 to limit the movable buckle strip 55 .

[0075] The width of the strip through groove 56 is consistent with the width of the strip limit block 48, ensuring that the strip limit block 48 is placed in the strip through groove 56, and at the same time limits the movable buckle strip 55. The length of the strip through groove 56 is longer than the length of the strip limit block 48, ensuring that the movable buckle strip 55 can move up and down while being limited.

[0076] In order to solve the problem of loading and installing the bobbin and how to perform double-position loading on the basis of only one station, the following features are specifically set:

[0077] The double-position material rack 20 also includes: two Z-shaped bases 21, the middle parts of the two Z-shaped bases 21 are fixedly arranged on the top of the support end of the single-layer bracket 11; two top plates 22, which are in a horizontal state, and one end of each top plate 22 is fixedly arranged on the bottom of the fixed end of the single-layer bracket 11. The distance between the two top plates 22 is greater than the distance between the two Z-shaped bases 21. At the same time, the two top plates 22 are centrally symmetrical, and the center of symmetry is the center point of the double-position material rack 20; the wire-releasing mechanism 23 includes: a limiting column sleeve 40, which is in a vertical state, the top end of the limiting column sleeve 40 is fixedly arranged on the bottom of one end of the top plate 22, and the bottom end of the limiting column sleeve 40 is fixedly arranged on one end of the Z-shaped base 21. At the top, a fault is formed in the middle of the limiting column sleeve 40; the locking device 24 includes: a locking column 25, the bottom of the locking column 25 is fixedly set on the top of the end of the Z-shaped base 21 where the limiting column sleeve 40 is not set, and the unlocking surface of each locking column 25 is facing away from the single-layer bracket 11; the middle axis of the feeding shaft 36 is connected to the roller 37, and the horizontal height of the roller 37 away from the center of the fixed base 9 is higher than the horizontal height of the other roller 37. The feeding shaft 36 also includes: a vertical shaft 39, which is in a vertical state, and the middle part of the vertical shaft 39 is fixedly set at one end of the feeding shaft 36. At the same time, the upper and lower ends of the vertical shaft 39 are connected to the inside of the limiting column sleeve 40 through the fault axis of the limiting column sleeve 40.

[0078] The two Z-shaped bases 21 are fixed at a certain distance from each other on the top of the supporting end of the single-layer bracket 11, and the non-fixed end of the first top plate 22 is connected to the end of the upper half of the Z in the first Z-shaped base 21 through a limiting column sleeve 40. Similarly, the non-fixed end of the first top plate 22 is connected to the end of the lower half of the Z in the first Z-shaped base 21 through a limiting column sleeve 40. The two locking columns 25 respectively fix the idle ends of the two Z-shaped bases 21, and the feeding shaft 36 is connected to the limiting column sleeve 40 through a vertical shaft. The roller 37 is axially connected to the middle part of the feeding shaft 36, and the end of the feeding shaft 36 is locked in the locking column 25. At the same time, the horizontal height of the wire-releasing mechanism 23 away from the center of the fixed base 9 is higher than the horizontal height of the other wire-releasing mechanism 23. This solves the problem of loading and installing the wire bobbin and how to perform double-position loading based on only one work station.

[0079] In order to achieve the effect of quick locking and fixing of the feeding shaft 36 after the bobbin is installed and convenient unlocking after the feeding is completed, the following features are specifically set:

[0080] The locking device 24 also includes: a movable locking block 33, which is in a vertical state and is slidably arranged inside the locking column 25. The side of the movable locking block 33 is formed with a horizontal lever 34, and one side of the bottom of the movable locking block 33 is formed with a vertical rounded corner portion 35; a second spring 32 is in a vertical state, and the bottom end of the second spring 32 is fixedly connected to the top of the movable locking block 33; the end of the feeding shaft 36 away from the vertical shaft 39 is formed with a rod-shaped lock head 38 for forcing the rounded corner portion 35 to slide, and the locking column 2 A lock receiving groove 26 for receiving a rod-shaped lock 38 is formed in the middle portion of the lock post 25.

A plug-in baffle 29 for fixing the top of the second spring 32 is slidably provided in the slot 28. A vertical avoidance groove 31 for accommodating the movement of the deflector rod 34 is formed at the bottom of one side of the slot 28. The vertical avoidance groove 31 is connected to the longitudinal receiving groove 27.

[0081] The movable locking block 33 is placed in the longitudinal accommodating groove 27, the lever 34 extends to the outside of the lock column 25 by avoiding the vertical groove 31, and the second spring 32 is between the insert baffle 29 and the movable locking block 33. When the insert baffle 29 is inserted into the slot 28, the movable locking block 33 moves from the longitudinal accommodating groove 27 to the bottom of the lock head accommodating groove 26 under the action of the second spring 32.

[0082] When locking, the feeding shaft 36 rotates clockwise and collides with the movable locking block 33. The rod-shaped lock head 38 presses the rounded corner portion 35 to slide upward.
