Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to an air-spinning box. Background Art

[0002] The spinning box is an important machine for cotton yarn processing. Its principle is to use a high-speed spinning rotor to wind cotton fibers into yarn. The lower side of the spinning box is generally open and provided with a cover plate, which is used to promptly remove the waste yarn stored in the spinning box. In the prior art, the cover plate is often directly driven to rotate by a cylinder, or the cover plate is driven by a cam connecting rod mechanism driven by a cylinder. These driving methods are all directly connected between the motion mechanism and the cover plate. After long-term operation, cotton fibers will enter the hinge between the cover plate and the cylinder or cam connection mechanism, and gradually accumulate and affect the formation of blockage. In order to ensure the smooth movement of the motion mechanism, the connection generally needs to be lubricated regularly. Lubricating oil is also easy to be contaminated with cotton fibers to form blockages, affecting the movement of the connection. It needs to be cleaned frequently, otherwise the cover body will not open smoothly or even get stuck, resulting in the cover body being unable to open, greatly affecting production efficiency.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0016] See also Figure 1 This embodiment provides an air-jet spinning box, which includes a box body 1, a cover body 2, a first magnet 3, a second magnet 4 and a driving component 5. The box body 1 is the air-jet spinning box, the cover body 2 is used to cover the lower opening of the box body 1, the first magnet 3 and the second magnet 4 attract or repel to close or open the cover body 2, and the driving component 5 is used to drive the first magnet 3 to rotate.

[0017] The lower side of the box body 1 is open, and the opening is used to release the contents of the box body 1. The cover body 2 is arranged below the box body 1 and is hinged to the box body 1 at one end, so that the cover body 2 can be rotated to open or close the opening. The cover body 2 is made of a non-magnetic material, such as a plastic cover or an aluminum cover.

[0018] The first magnet 3 is rotatably arranged on the side of the box body 1; the second magnet 4 is arranged on the side of the cover body 2 and is arranged opposite to the first magnet 3. When the first magnet 3 and the second magnet 4 attract each other, the cover body 2 and the box body 1 are closed; when the first magnet 3 and the second magnet 4 repel each other, the cover body 2 and the box body 1 are separated. When the cover body 2 is opened, the first magnet 3 and the second magnet 4 are at relatively far positions. In order to ensure that the first magnet 3 can attract the second magnet 4 after rotation, the positions of the first magnet 3 and the second magnet 4 cannot be too far apart. Therefore, the first magnet 3 and the second magnet 4 are generally arranged at a position close to the hinge between the box body 1 and the cover body 2, so that the distance between the first magnet 3 and the second magnet 4 will not be too far when the cover body 2 is opened. In order to ensure that there is sufficient attraction force when the cover 2 and the box body 1 are closed, the first magnet 3 and the second magnet 4 are magnets with greater magnetic force. Preferably, the first magnet 3 and the second magnet 4 are permanent magnets. Further preferably, the first magnet 3 and the second magnet 4 are neodymium iron boron magnets, and the magnetic force between the first magnet 3 and the second magnet 4 can be increased by setting multiple groups of neodymium iron boron magnets.

[0019] The driving assembly 5 can drive the first magnet 3 to rotate so that the first magnet 3 can be switched to a state of attraction or repulsion with the second magnet 4. In this embodiment, the two poles of the first magnet 3 are located on both sides. Therefore, rotating the first magnet 3 180 degrees can switch the first magnet 3 to a state of attraction or repulsion with the second magnet 4. Specifically, the driving assembly 5 includes a gear 51 and a rack 52. The gear 51 is fixedly connected to the first magnet 3 and is rotatably connected to the side of the housing 1; the rack 52 is slidably connected to the side of the housing 1 and meshes with the gear 51. Generally, a linear slide is used to connect the rack 52 to the housing 1. The gear 51 can be rotated by driving the rack 52 to move in a straight line, thereby rotating the first magnet 3. Generally, a linear drive device such as an electric cylinder or a pneumatic cylinder 53 can be used. Specifically, in this embodiment, the driving assembly 5 also includes a pneumatic cylinder 53. The fixed end of the cylinder 53 is fixedly connected to the side of the housing 1, and the driving end of the cylinder 53 is fixedly connected to the rack 52.

[0020] The protective cover 6 is arranged on the side of the box body 1, and the first magnet 3 and the driving assembly 5 are both arranged in the protective cover 6. The protective cover 6 can prevent cotton fibers from entering the first magnet 3 and the first driving assembly 5.

[0021] As a preferred embodiment, the first magnet 3, the second magnet 4, and the drive assembly 5 are each provided in two sets, one on each of two opposite sides of the housing 1. Providing two sets of the first magnet 3, the second magnet 4, and the drive assembly 5 can prevent uneven force on one side of the cover 2, which could result in the cover 2 not being able to fully close or open.

[0022] As a preferred embodiment, the air-jet spinning box further includes a limiting piece 7 and a limiting bolt 8. The limiting piece 7 is fixedly connected to the side of the cover body 2. The limiting piece 7 defines an arc-shaped limiting groove 71. A limiting hole 11 is defined on the side of the box body 1. The limiting hole 11 corresponds to the limiting groove 71. The limiting bolt 8 is disposed in the limiting groove 71 and is threadedly connected to the limiting hole 11. When the cover body 2 is opened, the limiting bolt 8 abuts against the upper portion of the limiting groove 71, limiting the cover body 2 from further downward rotation.

[0023] As a preferred embodiment, multiple limiting holes 11 are provided, and the multiple limiting holes 11 are arranged along the forming direction of the limiting groove 71. Providing multiple limiting holes 11 can place the limiting bolt 8 in different positions, thereby changing the opening degree of the cover body 2 and adapting to more application scenarios.

[0024] As a preferred embodiment, there are two limit plates 7 and two limit bolts 8, one on each of the two opposite sides of the box body 1. The presence of limit plates 7 and limit bolts 8 on both sides provides double-sided guidance, preventing the cover body 2 from being subjected to unilateral force and allowing the cover body 2 to rotate more smoothly.

[0025] The utility model provides an air-jet spinning box, in which a driving component drives the first magnet 3 to rotate, so that the first magnet 3 can switchably maintain an attractive or repulsive state with the second magnet 4, indirectly driving the cover 2 to close or open, and the first magnet 3 and the driving component 5 are both protected by a protective cover 6, preventing cotton fibers from entering the moving mechanism and accumulating to form a blockage, resulting in unsmooth movement of the moving mechanism.

[0026] The above specific embodiments of the present invention do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
