Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to an automatic diameter-changing yarn core and a yarn fluffing device. Background Art

[0002] The textile yarn bobbin is one of the necessary devices in the textile industry, but the traditional textile yarn bobbin has the following shortcomings during use: the diameter of the textile yarn bobbin (cotton core) is constant and cannot be adjusted. After the yarn is wound on the bobbin, it is very tight due to the high tension. If it is dyed directly, it is not conducive to the penetration of the dye, which greatly affects the dyeing effect. Therefore, before dyeing, it is necessary to replace the large diameter bobbin with a small diameter hollow bobbin to reduce the tension of the yarn and make it fluffy. This is not only a complicated process, time-consuming, and inefficient, but also after the bobbin is replaced, the yarn fluffiness is inconsistent, which will lead to uneven dyeing (there is a color difference between the inner and outer yarns, and the dyeing is not thorough).

[0003] Patent document CN114229095A discloses an integrated device for automatically replacing yarn tube cores and socks. The core changing device of the device is used to press down the core so that the core enters the yarn tube and causes the original old core in the yarn tube to detach from the yarn tube and fall downward into the silo. The invention can realize fully automatic yarn tube core changing. However, the device occupies a large space, the process is complicated, and two specifications of cores need to be prepared each time the device is used, which is costly. After replacing the new core, it is impossible to ensure that the cotton yarn wrapped on the new core is consistent in fluffiness, which will result in poor dyeing effect in the next step. At present, there is still a lack of a highly automated integrated yarn winding and loosening device. Summary of the invention

[0047] observe Figure 2 and Figure 3The first driving part includes a mounting seat fixed on the back side of the desktop 1.5, and a large pulley 1.3 and a driving wheel 1.2 connected by a belt drive are installed on the panel of the mounting seat facing the desktop 1.5 through an axis core. A first motor 1.1 is installed on the panel of the mounting seat away from the desktop 1.5. The output shaft of the first motor 1.1 passes through the mounting seat and is fixedly connected to the axis core of the driving wheel 1.2 through a coupling. When the first motor 1.1 is started, the driving wheel 1.2 is driven to rotate. Under the drive of the belt, the large pulley 1.3 rotates to drive the fixed base 1.9 to rotate rapidly.

[0058] The specific use and principle of this device,

[0059] 1) When in use, the upper die on the arm bar 2.4 is initially placed at the top, and the lower end of the fixed base 19 in the cotton core module 1 is manually inserted into the lower die 1.6 and passed through the table 1.5 until the semicircular convex card 1.12 on the convex body of the lower support seat of the mounting frame 1.14 is elastically released from the card slot on the inner wall of the perforation of the lower die 1.6. At the same time, the rotating shaft on the center line of the fixed base 19 is inserted into the plug rod 1.13 fixed to the surface of the large pulley 1.3 through the plug hole on it. At this time, the fixed base 19 is temporarily locked.

[0060] 2) Then start the first cylinder 2.9 to retract the piston rod of the first cylinder 2.9. At this time, the rack 2.10 moves to drive the cylindrical gear to rotate clockwise, and finally drives the upper die 2.6 to move toward the upper support seat convex body of the mounting frame 1.14, until the semicircular convex card 1.12 on the upper support seat convex body is pressed into the card slot in the upper die 2.6. At this time, the arm rod 2.4 is perpendicular to the limit block 2.3.

[0061] 3) Start the first motor 1.1 to drive the large pulley 1.3 to rotate clockwise. At this time, the semicircular convex card 1.12 on the lower support seat convex body of the installation frame 1.14 will leave the corresponding slot under the drive of the first motor 1.1. The semicircular convex card 1.12 will not be stuck in the slot under the continuous drive of the first motor 1.1. The yarn core curved outer wall 1.8 is expanded outward along the S-shaped cam groove in the self-locking cam 1.7 until it reaches the outermost end of the S-shaped cam groove. After the short rod of the L-shaped support rod 1.15 on the yarn core curved outer wall 1.8 and the center of the self-locking cam 1.7 are connected to form a straight line, the center line of the end of the S-shaped cam groove forms a 90-degree angle with this straight line, achieving the self-locking effect of the yarn core curved outer wall 1.8. After the core curved outer wall 1.8 is fully expanded, the cotton thread (yarn) is wound around the yarn core curved outer wall 1.8 until the cotton coil reaches a qualified diameter.

[0062] 4) Stop the first motor 1.1, and the cotton core module 1 will slowly stop rotating under the action of the semicircular convex card 1.12 and the card slot until it is fixed by the semicircular convex card 1.12 and the card slot. At this time, start the first motor 1.1 to rotate in the opposite direction. At this time, the curved outer wall 1.8 of the yarn core is gathered along the center line of the S-shaped cam groove in the self-locking cam 1.7 until it reaches the innermost end of the S-shaped cam groove. Similarly, the curved outer wall 1.8 of the yarn core is self-locked again, and the inner side of the cotton coil begins to loosen.

[0063] 5) Keep the rotation direction of the first motor 1.1 in step 4), and start the second motor 3.2 to drive the four cams 3.15 on the table 1.5 to rotate. Each cam 3.15 drives the corresponding connecting rod mechanism to make a reciprocating motion in the direction of the corresponding yarn core curved outer wall 1.8, and finally drives the push plate 3.6 to continuously beat the cotton coil, making the cotton coil as a whole more fluffy.

[0064] When the winding diameter of the cotton coil changes, the second cylinder 3.9 can be started to push the push frame 3.23, driving the limit slider 3.11 to move, so that the two hinge rods are closed to lift the height of the arc top plate 3.8, and the top block 3.7 on the arc top plate 3.8 is placed in the top lifting hole and abuts against the push rod 3.12 in the connecting rod mechanism. At this time, the position of the screw in the U-shaped groove adjusting rod is adjusted, and the pressure sensor 3.20 on the push plate 3.6 is used to adjust the appropriate stroke of the push plate 3.6. The device can also be used for cotton coils with different diameters.

[0065] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
