Description

Technical Field

[0001] The invention relates to the field of textile machinery, in particular to an air-jet spinning device. Background Art

[0002] In the air-spinning device, cotton strips are spun into yarn through a spinning machine, the formed yarn is wound on a bobbin, and after being wound to a predetermined length or weight, the yarn is cut and the full yarn roll is removed from the spinning station. This series of actions is called yarn doffing.

[0003] Some yarns need to be waxed before being wound onto the bobbin to increase the toughness of the yarn. However, since the yarn needs to be connected to the hook on the edge of the winding mechanism during the wiring process when the yarn is dropped, the yarn will interfere with the clamping block used to fix the wax block and cause the yarn to break, making it impossible to continuously produce and replace the bobbin yarn. Summary of the invention

[0004] The purpose of the present invention is to provide an air-spinning device which solves the problem of how to prevent yarn breakage during yarn dropping.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: The present invention provides an air-spinning device, comprising: A winding mechanism, the winding mechanism comprising a clamping jaw and a driving wheel for driving the bobbin on the clamping jaw; A wax block, the wax block is located at a position where the yarn passes before reaching the winding mechanism, and the wax block is supported by a clamping block; An auxiliary support bow is arranged on the side of the wax block, located on the side of the wax block that is closer to the hook position on the clamping claw. The auxiliary support bow is supported on the yarn so that the lower section of the yarn is not excessively deflected when the yarn is hung on the hook during the yarn dropping process.

[0006] Preferably, the auxiliary support bow is formed by bending a round rod.

[0007] Preferably, the position of the auxiliary support arch is adjustable.

[0008] Preferably, it also includes a yarn doffing trolley, which is provided with a suction tube and an anti-slip hook. The anti-slip hook is provided with barbs to prevent the yarn from slipping out after entering the anti-slip hook. The suction tube is used to suck the yarn head formed after the yarn is cut during yarn doffing.

[0009] Preferably, the surface of the auxiliary support arch is hardened.

[0010] Preferably, the auxiliary support bow extends to a set length in a direction perpendicular to the yarn swinging direction.

[0011] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The air-jet spinning device of the present invention is provided with an auxiliary support bow, which is located on the side of the wax block. When the yarn is dropped, the auxiliary support bow supports the yarn, so that when the yarn is hung on the hook on the clamping claw, it will not interfere with the clamping block of the wax block, so that the yarn is not easy to break, and the continuous production and replacement of the bobbin yarn can be achieved.

[0013] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] like Figure 1 In the air spinning device shown, after the yarn passes through the yarn sensor 7, it passes through the wax block 2, the surface of the yarn is waxed, and then the yarn is wound onto the bobbin 4. The two ends of the bobbin 4 are clamped by a pair of clamps 11 in the winding mechanism 1, and the bobbin 4 is in contact with the surface of the driving wheel 12, and the bobbin 4 is driven to rotate by the rotation of the driving wheel 12. After the yarn is wound onto the bobbin 4 to a certain extent, the yarn is doffed, that is, the yarn is cut, the clamp 11 releases the bobbin 4 and uses the push rod (not shown) on the doffing trolley to push the bobbin 4 out, and then a new bobbin 4 is loaded and connected to the cut yarn, leaving the yarn head. The yarn doffing operation can be referred to the Chinese patent document "CN117418336A".

[0015] When the yarn is wound on the bobbin 4, the yarn will swing back and forth along the axis of the bobbin 4. Figure 1 It swings back and forth between line A and line B.

[0016] During the yarn dropping process, after replacing the new bobbin 4, when wiring is required and the yarn head is connected to the hook (not shown) on the clamping jaw 11, the swing amplitude of the yarn will increase, which may interfere with the clamping block 5 used to fix the wax block 2, making the yarn easy to break, thereby preventing continuous production.

[0017] In this example, an auxiliary support bow 3 is provided on the side of the wax block 2. The auxiliary support bow 3 is located on the side of the wax block 2 that is biased toward the hook position on the clamping jaw 11. The auxiliary support bow 3 can support the yarn so that the lower section of the yarn will not be excessively deflected when the yarn is hung on the hook during the doffing process, so that the yarn will not interfere with the clamping block 5, and the yarn will not be scraped off by the clamping block 5, which is conducive to continuous production.

[0018] Figure 1 It is shown that the auxiliary support bow 3 is formed by bending a round rod, which not only protects the yarn and prevents the yarn from being worn off, but also makes the structure of the auxiliary support bow 3 light. Figure 2 The auxiliary support bow 3 extends a set length L in a direction perpendicular to the swinging direction of the yarn, which makes it easy for the yarn to be supported by the auxiliary support bow 3 and prevents the yarn from not being supported by the auxiliary support bow 3 due to the uncertainty of the swing.

[0019] The surface of the auxiliary support bow 3 may also be hardened to improve the durability of the auxiliary support bow 3. The position of the auxiliary support bow 3 is adjustable. In this example, the auxiliary support bow 3 is screwed to the frame by bolts, and the auxiliary support bow 3 can be adjusted by rotating, which is conducive to adjusting the auxiliary support bow 3 to a suitable position.

[0020] like Figure 2 and Figure 3 As shown, since the yarn is waxed, the broken yarn end is not easily sucked by the suction tube 61 when the yarn is dropped, so an anti-drop hook 62 is provided on the doffing trolley 6. The anti-drop hook 62 has barbs, and when the yarn swings into the anti-drop hook 62, it is not easy to fall out, thereby maintaining the position of the yarn, which is not only conducive to the scissors 63 cutting the yarn, but also makes it easy for the yarn end to be sucked by the suction tube 61 after the yarn is cut.

[0021] In summary, if Figure 1 In the air-jet spinning device of this example, an auxiliary support bow 3 is provided, so that when the cut yarn end is reconnected to the new bobbin 4 during yarn dropping, when the yarn swings to the hook on the clamp 11, the yarn is supported by the auxiliary support bow 3, and the lower section of the yarn will not swing to interfere with the right clamp block 5, so that the yarn will not be scraped off by the clamp block 5, thereby ensuring continuous production.

[0022] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
