DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0027] like Figures 1 to 9 As shown, the present embodiment discloses an automatic oil injection false twist device, comprising a housing 1 and a plurality of false twist units 2, wherein the false twist unit 2 comprises a false twist shaft 21, a bearing 22 is arranged on the outer side of the false twist shaft 21, a gear 26 is fixed to the lower end of the false twist shaft 21, and the gear 26 is located below the housing 1, a mounting hole 11 corresponding to the false twist unit 2 is arranged inside the housing 1, the false twist shaft 21 passes through the mounting hole 11, the bearing 22 is located in the mounting hole 11, the outer wall of the bearing 22 is sealed with the inner wall of the mounting hole 11, a top plate 6 is fixed to the upper part of the housing 1, the top plate 6 comprises a plurality of annular sleeves 61 corresponding to the mounting hole 11, the lower part of the annular sleeve 61 abuts against the upper part of the bearing 22, a positioning sleeve 23 is arranged on the outer side of the false twist shaft 21, and the annular sleeve 61 is sleeved on the outer side of the positioning sleeve 23, a bottom plate 7 is fixed to the lower part of the housing 1, a plurality of limiting plates 71 corresponding to the mounting hole 11 are arranged on the side of the bottom plate 7, and the limiting plates 71 abut against the lower part of the bearing 22.

[0028] In this embodiment, by providing the top plate 6 and the bottom plate 7, not only can the false twist unit 2 be fixed to the housing 1, but also the false twist unit 2 can be easily disassembled, thereby facilitating the maintenance and replacement of the false twist unit 2, and the operation is convenient. There are three false twist units 2, and the angle between the three false twist units 2 is 120°. An external driving gear (not shown in the figure) can be inserted between the gears 26 of the three false twist units 2, and the false twist shafts 21 of the three false twist units 2 can be synchronously driven to rotate through the external driving gear to realize the false twist operation.

[0029] like Figures 3 to 5 As shown, an oil groove 13 and a refueling channel 14 corresponding to the mounting hole 11 are provided inside the shell 1, the oil groove 13 is located between the multiple false twist units 2, the oil groove 13 is located at the center of the three false twist units 2, and lubricating oil is provided in the oil groove 13. One end of the refueling channel 14 is connected with the mounting hole 11 and the other end is connected with the oil groove 13. The refueling channel 14 is inclined downward from the oil groove 13 toward the mounting hole 11. An oil guide groove 25 is provided on the side of the bearing 22, and an oil inlet hole 24 is provided at the lower part of the oil guide groove 25. The oil inlet hole 24 is connected with the oil guide groove 25, and the oil inlet hole 24 is connected with the inside of the bearing 22. The refueling channel 14 is located at one end of the mounting hole 11 and can be connected with the oil guide groove 25.

[0030] The mounting hole 11 is connected to or blocked by the oil groove 13 through the partition 4. A guide groove 171 corresponding to the refueling channel 14 is provided in the shell 1. The refueling channel 14 is divided into a first channel 141 and a second channel 142 by the corresponding guide groove 171. The partition 4 includes a partition 41. The partition 41 is inserted into the guide groove 171. A through hole 42 is provided inside the partition 41. The partition 41 can move to connect the first channel 141, the through hole 42 and the second channel 142 or block the first channel 141 and the second channel 142.

[0031] When it is necessary to oil the bearing 22, the first oiling method is that the false twister stops working, the second channel 142 is connected to the oil guide groove 25, the partition 4 moves downward, driving the through hole 42 to move downward, and the first channel 141, the through hole 42 and the second channel 142 are connected. At this time, the lubricating oil in the oil groove 13 can flow from the first channel 141, the through hole 42 and the second channel 142 into the oil guide groove 25, and finally enter the bearing 22 from the oil inlet hole 24, so as to realize automatic oiling of the bearing 22. After the oiling is completed, the partition 4 moves upward to block the first channel 141 and the second channel 142. When the twisting unit 2 is working, the lubricating oil located at the bearing 22 will gradually deteriorate. Therefore, by setting a partition 41 that can move up and down, the mounting hole 11 and the oil groove 13 can be connected or blocked, so that not only the automatic oil filling operation of the bearing 22 can be realized, but also after the oil filling is completed, the lubricating oil in contact with the false twisting unit 2 and the clean lubricating oil located in the oil groove 13 are blocked, and the mixing of the lubricating oil in the two areas is effectively avoided, which effectively ensures the cleanliness of the oil in the oil groove 13 and sets a downwardly inclined refueling channel 14, which not only facilitates the refueling of the bearing 22, but also effectively prevents the lubricating oil from flowing back.

[0032] like Figure 5 As shown, a mounting groove 15 is provided at the bottom of the shell 1, and a partition rib 16 is provided in the mounting groove 15. A plurality of mounting cavities 17 are formed in the mounting groove 15 by the partition rib 16. The partition 4 is installed in the corresponding mounting cavity 17. A support plate 43 is provided at the lower part of the partition 41. A cover plate 5 is covered at the bottom of the mounting groove 15. A driving mechanism corresponding to the partition 4 is provided at the upper part of the cover plate 5. The driving mechanism includes an electromagnet 53 and a second spring 52 located on both sides of the electromagnet 53. The partition 4 is a metal part. The electromagnet 53 is used to attract the corresponding partition 4 to move the partition 4 downward. The lower end of the second spring 52 abuts against the upper part of the cover plate 5 and the upper end abuts against the lower part of the support plate 43. The second spring 52 pushes the partition 4 to move upward. A convex plate 51 is provided on the side of the cover plate 5. The convex plate 51 is fixed to the bottom of the shell 1 by bolts. A limit platform 44 corresponding to the second spring 52 is provided at the lower part of the support plate 43. The second spring 52 is sleeved on the outer side of the limit platform 44.

[0033] The driving method of the separator 4 is that when the corresponding separator 4 needs to be lowered, the electromagnet 53 below the corresponding separator 4 is energized, and the electromagnet 53 attracts the separator 4 located above it, so that the separator 4 is lowered; when the oil injection is completed, the electromagnet 53 is powered off, and the separator 4 can move upward and reset due to the elastic force of the second spring 52. By setting a driving mechanism composed of the second spring 52 and the electromagnet 53, not only can the automatic up and down movement of the separator 4 be realized, but also the structure is simple, the installation is convenient, and it is easy to assemble. In addition, the number of driving mechanisms is consistent with the number of separators 4, so that the movement of a single separator 4 can be realized, thereby realizing the oiling operation of a single false twist unit 2.

[0034] like Figure 1 and Figure 4 As shown, the upper part of the oil groove 13 is an opening and the opening is covered with a gas nozzle 3, the gas nozzle 3 includes an air inlet hole 34, the air inlet hole 34 is communicated with the oil groove 13, a steel ball 35 is arranged in the air inlet hole 34, and the end of the air inlet hole 34 away from the oil groove 13 is sealed by the steel ball 35, the upper part of the housing 1 is provided with a boss 18, the gas nozzle 3 includes an annular surface 31, the annular surface 31 abuts against the upper part of the boss 18, the lower part of the annular surface 31 is provided with an annular rib 32, the annular rib 32 is inserted into the oil groove 13 and is threadedly connected to the inner wall of the oil groove 13, and a sealing ring 38 is sleeved on the outer side of the annular rib 32, which is sealed The sealing ring 38 abuts against the inner wall of the oil groove 13, a connector 33 is provided on the upper part of the annular surface 31, the air inlet hole 34 passes through the connector 33, the upper end diameter of the air inlet hole 34 is smaller than the diameter of the steel ball 35, a first spring 36 is provided in the air inlet hole 34, a limit pin 37 is fixed at the lower end of the connector 33, the upper end of the first spring 36 abuts against the steel ball 35 and the lower end abuts against the upper part of the limit pin 37, an air pipe 9 is connected to the air nozzle 3, compressed air can pass through the air pipe 9, a fixing frame 12 is provided on the side of the shell 1, a bracket 100 is fixed on the upper part of the fixing frame 12, and the air pipe 9 passes through the bracket 100.

[0035] In this embodiment, through the cooperation of the steel ball 35, the first spring 36 and the air inlet hole 34, the air nozzle 3 is a structure similar to a one-way valve, which can effectively prevent the lubricating oil in the oil tank 13 from leaking out. When filling the oil tank 13 with lubricating oil, it is only necessary to unscrew the air nozzle 3 to directly add oil to the oil tank 13, which is easy to operate.

[0036] When the first refueling method is adopted, in order to improve the refueling efficiency, compressed air can be passed through the air pipe 9 during refueling. The compressed air can push the steel ball 35 to move downward, so that the oil groove 13 is connected with the air pipe 9, and the compressed air enters the oil groove 13, thereby achieving the purpose of rapid refueling; the present embodiment also has a second refueling method, that is, refueling during use. Specifically, when the false twist unit 2 is working, due to the high-speed rotation of the false twist shaft 21, the lubricating oil cannot directly enter the bearing 22. Therefore, pressure can be applied to the oil groove 13 by compressed air, and the lubricating oil in the oil groove 13 can be squeezed into the bearing 22 from the oil inlet hole 24, thereby realizing refueling during use. There is no need to stop the texturizing machine equipment, and the method of refueling while using can be realized, which can ensure production efficiency.

[0037] like Fig. 9 As shown, the oil guide groove 25 is vertically arranged, and the oil guide groove 25 includes an oil inlet section 251. The lower part of the oil inlet section 251 is provided with an oil passing section 252. The cross-sectional size of the oil passing section 252 is smaller than the cross-sectional size of the oil inlet section 251. The oil inlet hole 24 is located at the lower part of the oil passing section 252. The refueling channel 14 can be connected with the oil inlet section 251. Since the oil inlet hole 24 is connected with the inside of the bearing 22, when the false twist shaft 21 rotates at a high speed, part of the lubricating oil in the bearing 22 will overflow from the oil inlet hole 24. By reducing the area of ​​the section where the oil guide groove 25 and the oil inlet hole 24 are connected, the amount of lubricating oil in the bearing 22 can be effectively reduced, thereby ensuring the lubrication effect of the bearing 22 during operation.

[0038] When the false twist unit 2 is in use, the lubricating oil located inside the bearing 22, the oil inlet hole 24, the oil guide groove 25 and the oil use section of the second channel 142 is affected by the bearing 22, and the impurities inside the lubricating oil will increase. In the long run, it will cause wear of the bearing 22 and affect the service life of the bearing 22. When the bearing 22 is damaged, the false twist unit 2 needs to be replaced as a whole, which is relatively expensive.

[0039] like Figure 7 As shown, a liquid outlet 27 is provided on the side of the bearing 22, and the liquid outlet 27 is connected to the inside of the bearing 22, and the liquid outlet 27 is connected to the oil inlet 24. The internal structure of the bearing 22 is the prior art, and its specific structure is not repeated in this specification. A drainage hole 19 corresponding to the liquid outlet 27 is provided inside the housing 1, and one end of the drainage hole 19 is connected to the liquid outlet 27 and a sealing member 8 is installed on the other end. When it is necessary to drain the lubricating oil in the oil use section, the sealing member 8 is opened, and the drainage hole 19 is connected to the outside of the housing 1, so that the drainage operation can be realized to discharge the lubricating oil containing impurities, thereby improving the service life of the bearing 22. At the same time as the drainage, the inside of the bearing 22 needs to be injected with liquid.

[0040] The sealing member 8 comprises a pin sleeve 81 and a liquid outlet 82, wherein one end of the pin sleeve 81 is fixed to the housing 1 and the other end is threadedly connected to a plugging cover 83, a plug 84 is provided on the inner side of the plugging cover 83, and the plugging cover 84 can penetrate the liquid outlet 82 and be inserted into the drainage hole 19. By providing the plugging cover 83, the drainage hole 19 can be sealed. When draining, the plugging cover 83 is removed, and a negative pressure joint (not shown in the figure) is connected to the pin sleeve 81, and the lubricating oil inside the bearing 22 is drained by means of negative pressure, thereby improving the drainage effect.

[0041] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
