Description

Technical Field

[0001] The utility model relates to the technical field of textile machines, in particular to a front locking structure of a swing arm of a chenille spinning machine. Background Art

[0002] The chenille spinning machine is an efficient textile equipment specially used for producing and processing chenille yarn, and the swing arm is an important component of the textile machine. In related technologies, the swing arm is generally used in conjunction with a bracket, and the swing arm needs to be installed on the bracket through the main shaft and connecting components.

[0003] During use, when the swing arm is installed and used, long-term use may easily cause the front end of the installation to loosen. Therefore, a special locking structure is generally required to stabilize it and increase its service life. Traditional locking parts are mostly directly installed by bolts and protected by gaskets. The locking part is prone to loosening due to long-term friction and wear, and the tightening and stabilization effects are reduced. At the same time, the installation method of the above-mentioned bolts is also relatively fixed, single and complicated, which is not convenient for subsequent disassembly and replacement, thereby reducing the use effect.

[0004] Therefore, we propose a front locking structure for the swing arm of a chenille spinning machine to solve the above problems. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0029] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0030] The following describes a front locking structure for a swing arm of a chenille spinning machine provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0031] Example 1:

[0032] Combine Figure 1-Figure 3 As shown, the utility model provides a front locking structure of the swing arm of a chenille spinning machine.

[0033] Specifically, it includes a swing arm body 1, a main shaft 2, a connecting sleeve 3 and a locking sleeve 4. The swing arm body 1 is sleeved on the outside of the main shaft 2 through the connecting sleeve 3. The inner ring of the locking sleeve 4 is provided with a mounting groove 9. The upper and lower end surfaces of the inner part of the mounting groove 9 are symmetrically installed with multiple groups of support columns 11. The outer sides of the multiple groups of support columns 11 are all sleeved on the extrusion springs 12. One end of the multiple groups of support columns 11 is located on the inner side of the mounting groove 9 and is slidably provided with a top plate 13. One end of the top plate 13 is aligned with the multiple groups of support columns 11. There are multiple groups of extrusion grooves 19 at the corresponding locations. One end of each group of support columns 11 is located inside the multiple groups of extrusion grooves 19 and is connected to an extrusion plunger 20. The locking sleeve 4 is embedded with an embedded column 15. The locking sleeve 4 is embedded with an extruded arc-shaped embedded plate 14 connected to the other end of the top plate 13 at the abutment point. The left end of the main shaft 2 is provided with an embedded hole 10. The right end of the embedded hole 10 is located inside the main shaft 2 and is provided with a card that is locked with the side end face extending from the right end of the embedded column 15. The outer side of the right end extending end surface of the embedded column 15 is located inside the card slot 8 and is sleeved with an inflatable airbag 17. The inner side of the embedded column 15 is embedded with an air guide tube 22. The two end surfaces of the extruded arc panel 14 are provided with multiple through holes 21 connected to the multiple groups of extrusion grooves 19 and the left end of the air guide tube 22. The right side extending end of the air guide tube 22 is connected to the middle of the inflatable airbag 17. One end of the multiple groups of support columns 11 and the extrusion plunger 20 are slidably clamped inside the extrusion groove 19. When the locking sleeve 4 vibrates due to the use of the above components, the elastic action of the extrusion spring 12 on the outer side of the support column 11 inside the mounting groove 9 causes the top plate 13 to push the extruded arc-shaped panel 14 to continuously bounce, and the extrusion plunger 20 connected to one end of the support column 11 is continuously compressed and injected into the extrusion groove 19, and the gas is injected into the inflatable airbag 17 through the through hole 21 and the air guide tube 22, thereby maintaining the fastening effect and increasing the stability of the connection fastening.

[0034] Example 2:

[0035] Combine Figure 2 and Figure 3 As shown, based on the first embodiment,

[0036] Specifically, arc-shaped embedding grooves 18 are symmetrically formed at the upper and lower ends of the left side of the embedding column 15, and the arc-shaped surface of the extruded arc-shaped insert 14 is closely fitted into the arc-shaped embedding groove 18. By using the above-mentioned components and the components in Example 1, the left end of the embedding column 15 is installed inside the locking sleeve 4 by elastically squeezing the arc-shaped embedding groove 18 by extruding the arc-shaped insert 14, and at the same time, the right side of the embedding column 15 is embedded in the embedding hole 10. After flipping, the right end of the embedding column 15 is engaged with the engaging groove 8 and is fastened by the inflatable airbag 17 to complete the installation, thereby improving the convenience of installation and disassembly and improving the use effect.

[0037] Combine Figure 1 and Figure 2 As shown, in the above embodiment,

[0038] Specifically, the left side of the connecting sleeve 3 is located on the outside of the main shaft 2 and is sleeved on the pad 6. The pad 6 and the elastic ring 7 mainly squeeze the left side of the connecting sleeve 3 through the locking sleeve 4. At the same time, the wear resistance is enhanced by the protective wear-resistant effect of the extruded rubber pad 16. The right end of the connecting sleeve 3 is located on the outside of the main shaft 2 and is sleeved with a limiting baffle 5. The limiting baffle 5 is mainly used to limit and block the right side of the connecting sleeve 3 to prevent the swing arm body 1 from shifting its position. An elastic ring 7 is provided on the outside of the main shaft 2 between the pad 6 and the locking sleeve 4. The side surfaces of the pad 6 and the limiting baffle 5 are embedded with extruded rubber pads 16 at the connection between the left and right sides of the connecting sleeve 3.

[0039] The working principle and use process of the present invention are as follows: First, when the swing arm body 1 is used, the locking sleeve 4 vibrates, and the elastic action of the extrusion spring 12 outside the support column 11 inside the mounting groove 9 causes the top plate 13 to push the extruded arc-shaped panel 14 to continuously bounce, so that the extrusion plunger 20 connected to one end of the support column 11 is continuously compressed and injected into the extrusion groove 19 opened on the top plate 13, and the air is injected into the inflatable airbag 17 through the through hole 21 and the air guide tube 22, continuously maintaining the fastening effect and increasing the stability of the connection fastening. Secondly, the left end of the embedded column 15 is first embedded into the interior of the locking sleeve 4, and the air is injected into the airbag 17 through the through hole 21 and the air guide tube 22. The arc-shaped panel 14 is squeezed and inserted into the inner side of the arc-shaped embedding groove 18 of the embedding column 15. The top plate 13 inside the installation groove 9 and the extrusion spring 12 outside the support column 11 elastically squeeze the arc-shaped panel 14 and fix the embedding column 15. The right side of the embedding column 15 is then embedded in the embedding hole 10 and turned over and rotated so that the right end extension surface of the embedding column 15 is engaged with the engaging groove 8. The operation of the above-mentioned components, especially the continuous inflation of the inflatable airbag 17, improves the connection and fastening effect of the embedding column 15, and completes the installation. This embedded installation method is relatively convenient and also facilitates subsequent disassembly and replacement, thereby improving the use effect.

[0040] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
