Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of circular weaving machines, in particular to a door ring assembly of a suspension circular weaving machine. BACKGROUND

[0002] The suspension circular weaving machine is a new type of plastic weaving equipment. By adopting a suspension design, the weft shuttle is separated from the traditional rubber wheel fixed track during operation, and dynamic balance is achieved through a swing rod and a roller system, thereby greatly reducing the problem of rubber wheel wear.

[0003] In related technologies, the suspension circular weaving machine includes a door ring assembly and a shuttle. The door ring assembly includes an upper door ring and a lower door ring. A roller is rotatably arranged between the upper door ring and the lower door ring. The roller is connected to the upper door ring and the lower door ring through a rotating shaft. An axle sleeve for rotatably arranging the rotating shaft is arranged on the upper door ring and the lower door ring. The shuttle makes circular motion in the track formed by the roller to weave weft on the warp, and the roller also supports the upper door ring and the lower door ring.

[0004] However, when the roller of the above-mentioned suspension circular weaving machine is damaged, the upper door ring, the lower door ring, and all the rollers need to be completely separated, so that the distance between the upper door ring and the lower door ring is increased to replace the roller. It is not convenient to individually disassemble and replace a single roller, resulting in low fault maintenance efficiency, and thus needs to be improved. SUMMARY

[0005] In order to improve the maintenance efficiency of the roller of the suspension circular weaving machine, the present application provides a door ring assembly of a suspension circular weaving machine.

[0006] The door ring assembly of the suspension circular weaving machine provided by the present application adopts the following technical scheme: A door ring assembly of a suspension circular weaving machine includes an upper door ring and a lower door ring. A plurality of rollers are arranged between the upper door ring and the lower door ring. The roller includes a roller shaft arranged through the upper door ring and the lower door ring, and a sleeve rotatably arranged on the roller shaft. Threaded self-locking nuts are connected to both ends of the roller shaft. The two self-locking nuts are arranged on the sides of the upper door ring and the lower door ring away from each other. An upper cover and a lower cover are arranged through the roller shaft. The upper cover and the lower cover are arranged on both sides of the sleeve. The upper cover and the lower cover are arranged between the upper door ring and the lower door ring. The sleeve is rotatably arranged on the upper cover and the lower cover.

[0007] By adopting the above technical scheme, when a single roller needs to be replaced due to damage, only the two self-locking nuts need to be loosened, then the roller shaft is pulled out from the upper door ring and the lower door ring, the sleeve, the upper cover and the lower cover are taken out from between the upper door ring and the lower door ring, then the new sleeve is arranged in rotation between the new upper cover and the lower cover, the new upper cover, the lower cover and the sleeve are installed between the upper door ring and the lower door ring, then the new roller shaft is arranged in the upper door ring and the lower door ring, and the new roller shaft is arranged in the upper cover, the lower cover and the sleeve, and finally the self-locking nuts are tightened at both ends of the roller shaft. By the above way of replacing the roller, the upper door ring and the lower door ring do not need to be completely separated from all the rollers, and the replacement of a single roller can be realized, which simplifies the maintenance process, facilitates the replacement of the roller, and improves the maintenance efficiency of the roller.

[0008] Optionally, a deep groove ball bearing is arranged between the roller shaft and the sleeve, and rotating bearings are arranged at both ends of the sleeve, and the two rotating bearings are partially arranged in the upper cover and the lower cover and partially arranged in the sleeve.

[0009] By adopting the above technical scheme, when the roller rotates, the deep groove ball bearing can reduce the friction between the sleeve and the roller shaft, and the rotating bearing can reduce the friction between the sleeve and the upper cover and the lower cover, so that the rotation of the sleeve is more smooth, the rotation resistance of the sleeve is reduced, and the service life of the roller is prolonged, so that the shuttle rotates more smoothly in the circumferential track formed by the roller, and is not easy to jam, thereby improving the weaving quality of the circular weaving machine.

[0010] Optionally, a plurality of supporting members are arranged between the upper door ring and the lower door ring, both ends of the supporting member are fixedly connected to the upper door ring and the lower door ring, and the supporting member is arranged on both sides of each roller.

[0011] By adopting the above technical scheme, when one or more rollers are replaced individually, after the roller is removed from between the upper door ring and the lower door ring, the supporting member is supported between the upper door ring and the lower door ring, so that after part of the rollers are removed, the upper door ring and the lower door ring are not easy to collapse due to local lack of support, so that the upper door ring and the lower door ring are not easy to deform, and the service life of the door ring assembly is prolonged. When reinstalling the roller, the upper cover, the lower cover and the sleeve can be placed in the space formed between the two supporting members, the supporting member can limit the upper cover, the lower cover and the sleeve, so that the upper cover, the lower cover and the sleeve are not easy to dislocate or separate from the upper door ring and the lower door ring before the roller shaft is arranged, which facilitates the arrangement of the roller shaft, thereby facilitating the reinstallation of the roller, and further improving the maintenance efficiency of the roller.

[0012] Optionally, the outer side of the upper door ring and the lower door ring is rotationally provided with an unlocking ring, the unlocking ring comprises coaxially arranged mounting portions and unlocking portions, the mounting portions are rotationally connected with the upper door ring and the lower door ring, the unlocking portions are arranged on the sides of the two mounting portions away from each other, the side of the unlocking portion close to the upper door ring and the lower door ring is provided with transmission teeth, the circumference of the self-locking nut is provided with a transmission gear, the transmission gear is engaged with the transmission teeth, the two ends of the roller shaft are provided with connecting columns, the roller shaft is provided with a self-locking thread between the two connecting columns for threadedly connecting the self-locking nut, and the height of the transmission teeth in the vertical direction is greater than the height of the transmission gear in the axial direction.

[0013] By adopting the above technical scheme, when all the rollers need to be disassembled, the unlocking ring on the upper door ring and the lower door ring can be directly rotated, so that all the self-locking nuts are rotated in the loosening direction, without the need to manually loosen the self-locking nuts one by one, thereby saving the time for disassembling the rollers and further improving the efficiency of maintaining the rollers. When the rollers are installed, the self-locking nuts can be first arranged on the connecting columns at the two ends of the roller shaft, so that the transmission gear is engaged with the transmission teeth, and then the unlocking ring is rotated, so that all the self-locking nuts are rotated in the tightening direction, thereby synchronously tightening all the self-locking nuts without the need to use a screwdriver or other tools to tighten the self-locking nuts one by one. When the self-locking nuts are loose during use, the unlocking ring can be directly rotated to tighten the self-locking nuts, which is simple to operate. The all rollers can be quickly installed and disassembled, thereby improving the disassembly efficiency. The unlocking ring is arranged on the inner side of the door ring, and the operator does not need to touch the self-locking nuts in the narrow area, thereby reducing the maintenance difficulty.

[0014] Optionally, the mounting portion and the unlocking portion are detachably connected, a plurality of mounting grooves are formed in the mounting portion, and a plurality of mounting blocks are arranged on the unlocking portion, and the mounting blocks are in interference fit with the mounting grooves when the mounting portion and the unlocking portion are connected together.

[0015] By adopting the above technical scheme, when a certain roller needs to be individually disassembled or installed, the unlocking portion of the unlocking ring can be first disassembled from the mounting portion, that is, the mounting blocks are pulled out of the mounting grooves, so that the transmission teeth on the unlocking portion are separated from all the transmission gears, and then each transmission gear can be individually rotated, so that a certain self-locking nut can be individually loosened or tightened, thereby enabling a certain roller to be individually disassembled or replaced. When the number of self-locking nuts is small and the unlocking ring is not needed, the unlocking ring can be disassembled, and the self-locking nuts can be tightened in a normal manner, so that the unlocking ring is flexible in use and suitable for door ring assemblies of various types. When the transmission teeth of the unlocking portion are worn, the unlocking portion can be disassembled from the mounting portion, so that the unlocking portion can be individually replaced without replacing the mounting portion, thereby avoiding scrapping the entire unlocking ring and reducing the maintenance cost.

[0016] Optionally, the upper door ring and the lower door ring are both threadedly connected with a fixing bolt, the fixing bolt is used for fixing the unlocking ring and the upper door ring and the lower door ring, and the upper door ring, the lower door ring and the mounting portion are all provided with a fixing screw hole for threadedly connecting with the fixing bolt.

[0017] By adopting the technical scheme, when all the self-locking nuts are fastened, the fixing bolt can be screwed in the fixing screw hole, so that the position of the mounting portion is fixed relative to the upper door ring and the lower door ring, and the position of the unlocking ring is fixed, the unlocking ring is not easy to rotate randomly in the process of the shuttle making circumferential movement, so that the self-locking nut is not easy to loosen, and the stability of the door ring assembly is improved.

[0020] Optionally, the groove wall of the accommodating groove is provided with a limiting groove, the limiting piece comprises a limiting block slidingly arranged in the limiting groove and a return spring arranged between the limiting block and the groove wall of the limiting groove, the return spring has a tendency to drive the limiting block to extend into the accommodating groove, the limiting block is provided with a guide inclined surface, and the guide inclined surface is used for guiding the limiting block to retract into the limiting groove.

[0021] By adopting the above technical solution, when the linkage rod needs to be rotated out of the receiving slot, the limit block can be pushed into the limit slot so that the limit block no longer hinders the linkage rod from rotating out of the receiving slot. Then, the linkage rod will automatically rotate into the fixing slot under the action of gravity, thereby connecting the two unlocking rings. When the linkage rod needs to be locked in the receiving slot, the linkage rod can be directly rotated in the direction of entering the receiving slot so that the side wall of the linkage rod abuts against the guide inclined surface. Then, the limit block will enter the limit slot under the push of the linkage rod. When the linkage rod rotates to the side where the limit block is away from the lower door ring, the limit block will extend out of the limit slot under the action of the return spring and block the side of the linkage rod close to the lower door ring, thereby preventing the linkage rod from rotating out of the receiving slot at will and ensuring the stability of the linkage rod.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to remove a roller individually, you can simply loosen the self-locking nut and then pull out the roller. You can then remove the upper cover, lower cover, and sleeve of one of the rollers individually, improving the maintenance efficiency of a single roller. 2. When all or most rollers need to be disassembled, multiple self-locking nuts can be loosened or tightened simultaneously by turning the unlocking ring, further improving maintenance efficiency; 3. The fixing bolts fix the unlocking ring on the upper door ring and the lower door ring, so that the transmission teeth are always engaged with the transmission gear, so that the self-locking nut is not easy to loosen during the operation of the circular loom, thereby improving the stability of the door ring assembly.
