Description

Technical Field

[0001] The invention relates to the technical field of spinning machinery, in particular to a quick-replacement grid ring mechanism for concentrated spinning. Background Art

[0002] Compact spinning is a new spinning process based on the upgrade of traditional ring spinning technology. Its core is to add a fiber gathering area after the drafting device of the ring spinning frame. According to the gathering principle, it can be divided into airflow gathering type and mechanical gathering type. The airflow gathering type uses airflow to gather the fiber bundles on the grid ring to a fixed range, forming tightly arranged fiber strands, reducing edge fiber diffusion and hairiness. The pore structure on its surface, combined with the lateral airflow, promotes the fiber to gather towards the center, optimizing the fiber arrangement density.

[0003] In the prior art, the patent with announcement number: CN108754699B discloses a support mechanism for a mesh ring of a shaped tube for concentrated spinning, which is used to replace the traditional mesh ring tension mechanism. The mesh ring is loosely sleeved between the shaped tube, the gathering roller and the support mechanism, so that the accumulated flowers generated on the inner surface of the mesh ring can easily pass over the high point (support arm wear-resistant sheet) of the support mechanism and move with the mesh ring to the gathering groove position of the shaped tube to be sucked away in time, thereby reducing the accumulation of flowers in the concentrated spinning device, greatly extending the spinning cleaning cycle, and keeping the mesh ring rotating flexibly, thereby effectively ensuring the yarn hairiness index and yarn strength;

[0004] However, the mesh rings are consumed quickly during the spinning process, and need to be replaced when they are damaged or severely worn. When replacing the mesh rings, the mesh ring support mechanism described in the above technology needs to pull the support arm and rotate it to the other side of the lower limit stop of the support arm mounting plate before the mesh rings can be removed or installed. A group of special-shaped tubes are usually equipped with multiple groups of mesh rings. When replacing the mesh rings located on the inner side of the special-shaped tube, the support arms on the outer side of the mesh ring to be replaced need to be pulled down in turn before replacement can be carried out. The operation is inconvenient and the replacement efficiency is low. In addition, the above-mentioned support mechanism is not convenient for adjusting the tension according to different types of mesh rings, and its scope of application is small.

[0042] A quick-change licker-in mechanism for compact spinning proposed by the present invention. When the licker-in 3 needs to be replaced, by pressing the main end cap 72, the main telescopic rod 7 is driven to retract into the inside of the telescopic hole 43. The main telescopic rod 7 drives the auxiliary telescopic rod 8 to move towards the right plug 6 through the extension rod 73 and the threaded rod 74, so that the main positioning column 71 disengages from the inside of the main positioning groove 53, and at the same time the auxiliary positioning column 82 disengages from the inside of the auxiliary positioning groove 63. At this time, the fixed base support plate 4 is controlled to rotate around the support plate rotating shaft 42, so that the side of the fixed base support plate 4 close to the licker-in 2 rotates towards the direction close to the profiled tube 1, so that all the fixed bases 9 on the surface of the fixed base support plate 4 move synchronously, reducing the diameter of the frame composed of the support body, the profiled tube 1 and the licker-in 2, enabling the licker-in 3 to quickly disengage from the position close to the inner side of the profiled tube 1 or quickly install the licker-in 3 to the position close to the inner side of the profiled tube 1, avoiding the problem of needing to pull down multiple groups of support arms 92 in sequence when replacing the licker-in 3, and improving the efficiency of replacing the licker-in 3.

When cleaning the inside of the profiled tube 1, the main telescopic rod 7 and the auxiliary telescopic rod 8 are rotated through the main end cap 72 and the auxiliary end cap 83, so that the threaded rod 74 disengages from the inside of the threaded hole 81, thereby facilitating the removal of the left plug 5 and the right plug 6 from both ends of the profiled tube 1.

[0045] Working principle: Compact spinning is a new spinning process based on the upgrade of traditional ring spinning technology. For a quick grid ring replacement mechanism for compact spinning proposed in the present invention, when it is necessary to replace the grid ring 3, pressing the main end cap 72 drives the main telescopic rod 7 to retract into the interior of the telescopic hole 43. The main telescopic rod 7 drives the auxiliary telescopic rod 8 to move towards the right plug 6 through the extension rod 73 and the threaded rod 74, causing the main positioning column 71 to disengage from the interior of the main positioning groove 53. At the same time, the auxiliary positioning column 82 disengages from the interior of the auxiliary positioning groove 63. At this time, control the fixed base support plate 4 to rotate around the support plate rotating shaft 42, so that the side of the fixed base support plate 4 close to the compact roller 2 rotates towards the direction close to the profiled tube 1. Thus, all the fixed bases 9 on the surface of the fixed base support plate 4 move synchronously, reducing the diameter of the frame formed by the support body, the profiled tube 1, and the compact roller 2, enabling the grid ring 3 to quickly disengage from the position close to the inner side of the profiled tube 1 or quickly install the grid ring 3 to the position close to the inner side of the profiled tube 1, avoiding the problem of needing to pull down multiple groups of support arms 92 in sequence when replacing the grid ring 3. The main positioning column 71 and the auxiliary positioning column 82 (please verify how the hole is inserted into the positioning groove) are respectively inserted into the corresponding main positioning groove 53 and auxiliary positioning groove 63, realizing the fixation of the side of the fixed base support plate 4 close to the compact roller 2 at different heights, thereby realizing the change of the diameter of the frame formed by the support body, the profiled tube 1, and the compact roller 2, and further being able to adapt to more models of grid rings 3, improving its applicability.
