Description

Technical Field

[0001] This utility model relates to the field of compact spinning technology, specifically to a wear-resistant sheet for a compact spinning negative pressure tube. Background Technology

[0002] In compact spinning technology, the negative pressure tube is the core component for achieving fiber aggregation. It uses negative pressure airflow to tightly arrange the drafted fibers, thereby reducing yarn hairiness and improving yarn quality. However, during long-term operation, the surface of the negative pressure tube is in direct contact with the high-speed moving fibers, which can easily lead to wear due to friction, thus affecting airflow stability and equipment lifespan.

[0003] Publication No. CN112481754A discloses a wear-resistant component for a compact spinning negative pressure tube. The wear-resistant sheet used combines the wear resistance of ceramics with the plasticity of plastics, which can significantly improve the service life of existing wear-resistant components. Moreover, its structure is simple and easy to install. However, this patent still has the following problems in actual use:

[0004] Although this type of wear-resistant sheet for a compact spinning negative pressure tube combines the wear resistance of ceramics with the plasticity of plastics, which can significantly improve the service life of existing wear-resistant parts and is easy to install, the lack of anti-deviation measures on the wear-resistant sheet makes it easy for the mesh ring that plays the role of conveying sliver to move left and right during the operation of the compact spinning equipment, resulting in unstable sliver conveying, which in turn leads to a decrease in spinning quality and affects the performance of the compact spinning device.

[0005] A wear-resistant sheet for use in compact spinning negative pressure tubes is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a wear-resistant sheet for a negative pressure tube in compact spinning, so as to solve the problem mentioned in the background art. The wear-resistant sheet of the current wear-resistant parts has both the wear resistance of ceramics and the plasticity of plastics, which can greatly improve the service life of existing wear-resistant parts and is easy to install. However, the wear-resistant sheet does not have anti-deviation measures, which can easily cause the mesh ring that plays the role of conveying sliver to move left and right during the operation of the compact spinning equipment, resulting in unstable sliver conveying, which in turn leads to a decrease in spinning quality and affects the performance of the compact spinning device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant sheet for a compact spinning negative pressure tube, comprising a guiding mechanism and a wear-resistant sheet body mounted on the surface of the guiding mechanism;

[0008] One end of the guide mechanism is provided with a self-locking mechanism, and the inner wall of the self-locking mechanism is attached to the outer side of one end of the negative pressure pipe body.

[0009] Also includes:

[0010] The guiding mechanism includes a negative pressure tube body, and an airflow hole is provided on one side of the negative pressure tube body;

[0011] Among them, a wear-resistant plate body is attached to the surface of the negative pressure tube body near the airflow hole, and the two ends of the wear-resistant plate body are engaged with the negative pressure tube body.

[0012] The wear-resistant sheet body has a negative pressure through hole at the center of its surface, and the position of the negative pressure through hole is aligned with the position of the airflow hole.

[0013] Preferably, baffles are fixedly connected to both sides of the wear-resistant sheet body near the negative pressure through hole.

[0014] Preferably, the self-locking mechanism includes a first retaining ring, both sides of the inner wall of the first retaining ring are fitted and connected to the negative pressure pipe body, one end of the first retaining ring is fitted and connected to a second retaining ring, and the front and rear sides of the upper and lower ends of the second retaining ring are fitted and connected to a first splicing block.

[0015] Preferably, an arc groove is formed on one side of the first splicing block, a rubber column is fitted inside the arc groove, a lever is rotatably connected to the outside of the rubber column, and the outside of the lever is slidably connected to the first splicing block.

[0016] Preferably, a first hemisphere is fixedly connected to one end of the lever, the outer side of the first hemisphere is rotatably connected to the first splicing block, and a second hemisphere is attached to the side of the first hemisphere away from the lever.

[0017] Preferably, a second splicing block is provided on the outer side of the second hemisphere, the internal structure of the second splicing block is consistent with the internal structure of the first splicing block, and one side of the outer side of the second splicing block is fitted and connected to the first retaining ring.

[0018] Preferably, countersunk holes are provided inside both the upper and lower ends of the first splicing block.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This wear-resistant sheet for a tightly spun negative pressure tube, by setting a guiding mechanism, can not only reduce fuzz and fly waste, but also prevent the mesh ring from swaying left and right. By setting a self-locking mechanism, it can facilitate the disassembly and assembly of the negative pressure tube body, thereby facilitating the replacement of the wear-resistant sheet body and the mesh ring in the future. The specific details are as follows:

[0020] 1. By setting a guiding mechanism, not only can fuzz and fly waste be reduced, but the left and right swaying of the mesh ring can also be prevented. By using the negative pressure through holes on the wear-resistant plate body and the cooperation of the negative pressure system, the airflow distribution in the gathering area can be adjusted to ensure that the fibers are tightly arranged before twisting, thereby reducing fuzz and fly waste. By using the cooperation between the baffle and the wear-resistant plate body, the left and right swaying of the mesh ring can be restricted. By setting the wear-resistant plate body, the direct friction between the fibers and metal parts during high-speed operation can be reduced, and the gathering device can be prevented from deforming or being damaged due to long-term friction, thus reducing equipment maintenance costs.

[0021] 2. The self-locking mechanism facilitates the disassembly and assembly of the negative pressure pipe body, thereby facilitating the replacement of the wear-resistant sheet body and the mesh ring later. The first and second hemispheres in an inclined state can limit the first and second splicing blocks, thereby keeping the first and second retaining rings in a closed state, which can realize the splicing between the negative pressure pipe bodies. The friction between the rubber column and the first splicing block can limit the position of the hemispheres, thereby improving the stability of the closure of the first and second retaining rings.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-9 The present invention provides a technical solution: a wear-resistant sheet for a compactly spun negative pressure tube, comprising a guide mechanism 1 and a wear-resistant sheet body 103 mounted on the surface of the guide mechanism 1; a self-locking mechanism 2 is provided at one end of the guide mechanism 1, and the inner wall of the self-locking mechanism 2 is attached to the outer side of one end of the negative pressure tube body 101; the guide mechanism 1 includes a negative pressure tube body 101, and an airflow hole 102 is provided on one side of the negative pressure tube body 101. The edge of the airflow hole 102 guides the fibers to be tightly arranged along the axial direction, reducing lateral diffusion. The airflow speed and direction are adjusted by the geometry of the airflow hole 102 to optimize the fiber aggregation effect.

[0034] A wear-resistant plate body 103 is attached to the surface of the negative pressure tube body 101 near the airflow hole 102. The two ends of the wear-resistant plate body 103 are engaged with the negative pressure tube body 101. The two ends of the wear-resistant plate body 103 are arc-shaped to facilitate them being snapped onto the surface of the negative pressure tube body 101.

[0035] A negative pressure through hole 104 is provided at the center of the surface of the wear-resistant sheet body 103. The position of the negative pressure through hole 104 is aligned with the position of the airflow hole 102. By connecting the airflow hole 102 with the negative pressure through hole 104, a local negative pressure zone is formed to adsorb the fiber into the groove.

[0036] Baffles 105 are fixedly connected to both sides of the wear-resistant plate body 103 near the negative pressure through hole 104. By setting baffles 105, the mesh ring on the surface of the wear-resistant plate body 103 can be prevented from swaying left and right during operation, thus affecting the quality of the product.

[0037] The self-locking mechanism 2 includes a first retaining ring 201. Both sides of the inner wall of the first retaining ring 201 are attached to the negative pressure pipe body 101. A second retaining ring 202 is attached to one end of the first retaining ring 201. A first splicing block 203 is attached to both the front and rear sides of the upper and lower ends of the second retaining ring 202. The external structures of the two components, the first retaining ring 201 and the second retaining ring 202, are the same.

[0038] An arc groove 204 is provided on one side of the first splicing block 203. A rubber column 205 is fitted inside the arc groove 204. A lever 206 is rotatably connected to the outside of the rubber column 205. The outside of the lever 206 is slidably connected to the first splicing block 203. By setting the rubber column 205, the friction can be increased to prevent the hemisphere from rotating.

[0039] One end of the lever 206 is fixedly connected to a first hemisphere 207. The outer side of the first hemisphere 207 is rotatably connected to the first splicing block 203. The side of the first hemisphere 207 away from the lever 206 is fitted with a second hemisphere 208. By using the first hemisphere 207 and the second hemisphere 208 in an inclined state, the first splicing block 203 and the second splicing block 209 can be limited, thereby making the first retaining ring 201 and the second retaining ring 202 in a closed state, thus realizing the splicing and fixing between the negative pressure pipe body 101.

[0040] A second splicing block 209 is provided on the outer side of the second hemisphere 208. The internal structure of the second splicing block 209 is the same as that of the first splicing block 203. One side of the outer side of the second splicing block 209 is fitted and connected to the first retaining ring 201. The upper and lower ends of the first splicing block 203 are provided with countersunk holes 210. Bolts are provided inside the countersunk holes 210. By using the thread action between the bolts and the first retaining ring 201 and the second retaining ring 202, the first splicing block 203 and the second splicing block 209 can be fixed to the outside of the second retaining ring 202 and the first retaining ring 201, respectively.

[0041] Working principle: Before using this type of wear-resistant sheet for compact spinning negative pressure tubes, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 9 As shown, when fiber debris or dust accumulates in the airflow hole 102, it can easily lead to uneven negative pressure. If the wear-resistant plate body 103 needs to be replaced, the negative pressure tube body 101 must be disassembled first, and then the wear-resistant plate body 103 and the mesh ring can be replaced.

[0042] First, the rubber column is moved in the arc groove by the lever, thereby causing the first hemisphere 207 and the second hemisphere 208 to rotate. When the horizontal plane of the first hemisphere 207 and the second hemisphere 208 is flush with the side of the splicing block, the first splicing block 203 and the second splicing block 209 can release the restriction on the first retaining ring 201 and the second retaining ring 202, thereby realizing the disassembly of the negative pressure pipe body 101.

[0043] Next, remove the mesh ring from the surface of the wear-resistant plate body 103, and then remove the wear-resistant plate body 103 from the negative pressure tube body 101 to expose the airflow hole 102 and align it for cleaning.

[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
