Description

Technical Field

[0001] This utility model relates to the field of circular loom technology, and in particular to a shuttleless circular loom door ring assembly. Background Technology

[0002] In the prior art, the door ring assembly includes an upper door ring, a lower door ring, support rollers, and a shuttle plate. Several support rollers are spaced apart along the circumference, and the several support rollers cooperate to form a shuttle track for the shuttle plate to pass through. The support rollers are rotatably fitted with abutment rollers for abutting the shuttle plate. However, during assembly, the support rollers are usually assembled by using a main shaft that runs through the upper and lower door rings and is locked with a nut. In this way, when a single abutment roller on the support roller is damaged, the entire support roller needs to be removed and replaced, which is relatively troublesome during assembly and disassembly. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a shuttleless circular loom door ring assembly. The shuttle plate does not need to be equipped with a shuttle wheel. It can shuttle between the first abutting wheel and the second abutting wheel through the raised part. When one of the first abutting wheel and the second abutting wheel is damaged and needs to be replaced, the corresponding abutting wheel can be directly removed to replace one of them. It is not necessary to remove the whole thing. Replacement is more convenient and the structure is relatively simple.

[0004] This utility model discloses a shuttleless circular loom door ring assembly, including an upper door ring, a lower door ring, and a shuttle plate. The upper door ring is detachably connected to a suspension shaft, which is spaced out along the circumference. Each suspension shaft has a first abutting wheel rotatably mounted on it. The lower door ring is detachably connected to a support shaft, which is also spaced out along the circumference. Each support shaft has a second abutting wheel rotatably mounted on it. The first and second abutting wheels correspond one-to-one and are spaced apart to form a first shuttle channel. The shuttle plate has a raised portion corresponding to the first shuttle channel. The first and second abutting wheels gradually decrease in size from the end furthest from the first shuttle channel to the end closest to the first shuttle channel, forming a conical surface. Anti-slip sleeves are fitted onto the conical surface, and these anti-slip sleeves are also conical in shape. The conical surfaces cooperate to form a second shuttle channel, and the bottom of the shuttle plate abuts against the second shuttle channel.

[0005] A further feature of this invention is that the suspension shaft is provided with a first threaded section, which is threadedly engaged with the upper door ring, and the support shaft is provided with a second threaded section, which is threadedly engaged with the lower door ring. The threads of the first threaded section and the second threaded section are arranged in opposite directions.

[0006] A further feature of this invention is that bearings are provided on both the suspension shaft and the support shaft, and the first abutting wheel and the second abutting wheel are sleeved on the corresponding bearings.

[0007] A further feature of this invention is that anti-detachment snap rings are provided on both the suspension shaft and the support shaft, with the anti-detachment snap rings located at opposite ends of the first and second abutting wheels.

[0008] Using the above technical solution, the upper and lower door rings are fixed on the circular loom during use. The first and second abutment wheels are separately designed, allowing them to be replaced individually, thus simplifying the replacement process and reducing replacement costs. When the shuttle moves along the loom, it rests against the anti-slip sleeve. The conical surface provides support and guidance, preventing the shuttle from wobbling and ensuring stable movement of the shuttle in the second shuttle channel. Furthermore, the raised portion is located within the first shuttle channel, further preventing the shuttle from wobbling during movement. Currently, the conical surface on the market is directly formed from the anti-slip sleeve, resulting in inconsistent thickness and reduced stability. The first and second abutment wheels are directly conical, and the anti-slip sleeve only needs to be fitted onto the corresponding abutment wheel, avoiding inconsistent anti-slip sleeve thickness.

Detailed Implementation

[0010] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0011] This utility model discloses a shuttleless circular loom door ring assembly, including an upper door ring 1, a lower door ring 2, and a shuttle plate 3. In this embodiment, a suspension shaft 4 is detachably connected to the upper door ring 1, and several suspension shafts 4 are spaced apart along the circumferential direction. Each suspension shaft 4 is rotatably equipped with a first abutment wheel 5. A support shaft 6 is detachably connected to the lower door ring 2, and several support shafts 6 are spaced apart along the circumferential direction. Each support shaft 6 is rotatably equipped with a second abutment wheel 7. The abutting wheel 5 and the second abutting wheel 7 are arranged in a one-to-one correspondence and at intervals to form the first shuttle channel 8. The shuttle plate 3 is provided with a raised part 9 corresponding to the position of the first shuttle channel 8. The first abutting wheel 5 and the second abutting wheel 7 gradually become smaller from the end away from the first shuttle channel 8 to the end closer to the first shuttle channel 8 to form a conical surface. The anti-slip sleeve 10 is fitted on the conical surface, and the anti-slip sleeve 10 is also formed in a conical distribution. The conical surface cooperates to form the second shuttle channel 11. The bottom of the shuttle plate 3 abuts against the second shuttle channel 11.

[0012] Using the above technical solution, when in use, the upper door ring 1 and the lower door ring 2 are fixed on the circular loom. The first abutting wheel 5 and the second abutting wheel 7 are set separately, so they can be replaced individually, thereby simplifying the replacement process and reducing the replacement cost. When the shuttle plate 3 shuttles, it abuts against the anti-slip sleeve 10. The conical surface can play a supporting and guiding role to prevent the shuttle plate 3 from shaking, so that the shuttle plate 3 can shuttle stably in the second shuttle channel 11. Furthermore, the raised part 9 is located in the first shuttle channel 8, which can further prevent the shuttle plate 3 from shaking when it shuttles. Currently, the conical surface on the market is directly formed by the anti-slip sleeve, which makes the thickness of the anti-slip sleeve inconsistent and reduces its stability. The first abutting wheel 5 and the second abutting wheel 7 are directly conical, and the anti-slip sleeve only needs to be fitted onto the corresponding abutting wheel, which can avoid the situation of inconsistent thickness of the anti-slip sleeve.

[0013] The suspension shaft 4 is provided with a first threaded section 12, which is threaded onto the upper door ring 1. The support shaft 6 is provided with a second threaded section 13, which is threaded onto the lower door ring 2. The threads of the first threaded section 12 and the second threaded section 13 are reversed. Using threaded engagement can further simplify the assembly process. With the threads of the first threaded section 12 and the second threaded section 13 reversed, when the shuttle plate 3 moves through, it will simultaneously tighten the suspension shaft 4 and the support shaft 6 to prevent one of them from loosening. Of course, a nut can also be used to lock the suspension shaft 4 and the support shaft 6.

[0014] Bearings 14 are provided on both the suspension shaft 4 and the support shaft 6. The first abutting wheel 5 and the second abutting wheel 7 are sleeved on the corresponding bearings 14, which can reduce the friction of the rotation of the first abutting wheel 5 and the second abutting wheel 7, and also prevent the first abutting wheel 5 and the second abutting wheel 7 from coming off.

[0015] Both the suspension shaft 4 and the support shaft 6 are equipped with anti-detachment snap rings 15. The anti-detachment snap rings 15 are located at opposite ends of the first abutting wheel 5 and the second abutting wheel 7, which can further prevent the first abutting wheel 5 and the second abutting wheel 7 from detaching.
