Description

Technical Field

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

[0002] In the prior art, the gate ring assembly of a circular loom includes an upper gate ring, a lower gate ring, support rollers, and a shuttle plate. Several support rollers are spaced apart along the circumference, and these support rollers cooperate to form a shuttle track for the shuttle plate to pass through. An abutment roller for abutting the shuttle plate is rotatably sleeved on the support roller. However, the abutment roller is usually installed using two horizontally arranged shafts. These shafts are usually relatively thin and prone to deformation after long-term use. For example, Chinese utility model patent application number 202422331183.7 uses an installation plane to set the mounting shaft and installs the abutment roller through the mounting shaft. If the diameter of the mounting shaft is too small, it is prone to deformation; if the diameter of the mounting shaft is too large, the abutment roller cannot be installed. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a door ring assembly for a shuttleless circular loom, in which the abutment roller is directly sleeved on the support shaft. The support shaft has a large diameter and good stability, which can increase the stability of the abutment roller.

[0004] This utility model discloses a door ring assembly for a shuttleless circular loom, including an upper door ring, a lower door ring, and support rollers. Several support rollers are spaced apart along the circumference, and these support rollers cooperate to form a shuttle track for the shuttle plate to pass through. Each support roller includes an abutment roller and a support shaft. The upper and lower door rings each have a support column corresponding to the position of each support roller. The support column has an inwardly extending mounting plate. The support shaft passes through the mounting plate, and the abutment roller is rotatably sleeved on the support shaft. The abutment roller includes an upper roller group and a lower roller group. The upper and lower roller groups are spaced apart and located on opposite sides of the mounting plate, forming a guide groove for the shuttle plate to partially enter. Both the upper and lower roller groups have conical abutment surfaces that abut against the shuttle plate, and these conical abutment surfaces cooperate to form a figure-eight abutment surface.

[0005] A further feature of this invention is that both the upper roller assembly and the lower roller assembly include a first abutting wheel and a second abutting wheel. The first abutting wheel is located close to the mounting plate and on opposite sides of the guide groove. The second abutting wheel is located outside the first abutting wheel, and a conical abutting surface is provided on the second abutting wheel.

[0006] A further feature of this invention is that: bearings are provided at both ends of the support shaft corresponding to each of the second abutting wheels; the first abutting wheel is sleeved on the second abutting wheel and rotates synchronously with it; the first abutting wheel covers the bearing at one end of the second abutting wheel; and a dust cover is provided on the bearing at the other end of the second abutting wheel, so that the dust cover covers the top and bottom of the support shaft.

[0007] A further feature of this invention is as follows: a first pull rod is provided on the upper door ring at the top corresponding to the support shaft, one end of the first pull rod is pulled on the support shaft, and the other end is fixedly provided on the upper door ring; a second pull rod is provided on the lower door ring at the bottom corresponding to the support shaft, one end of the second pull rod is pulled on the support shaft, and the other end is fixedly provided on the lower door ring; and both the first pull rod and the second pull rod are located inside the support shaft.

[0008] A further feature of this invention is that one end of the first pull rod that mates with the support shaft is fixed or integrally mounted on the dust cover at the top of the support shaft, and one end of the second pull rod that mates with the support shaft is fixed or integrally mounted on the dust cover at the bottom of the support shaft.

[0009] The beneficial effects of this utility model are as follows: it is supported between the upper and lower door rings by the support column, and the support shaft is installed by the mounting plate. The abutment roller is directly sleeved on the support shaft. The guide groove allows the shuttle plate to enter and play a role in shuttle guidance, preventing the shuttle plate from moving up and down. The upper roller group and the lower roller group can be used for the shuttle plate to abut when it shuttles. The figure-eight abutment surface can increase the contact area with the shuttle plate.

[0012] This utility model discloses a door ring assembly for a shuttleless circular loom, including an upper door ring 1, a lower door ring 2, and support rollers 3. Several support rollers 3 are spaced apart along the circumference, and these support rollers 3 cooperate to form a shuttle track for the shuttle plate to pass through. Each support roller 3 includes an abutment roller 31 and a support shaft 32. In this embodiment, support columns 4 are provided at the positions of each support roller 3 on the upper door ring 1 and lower door ring 2. The support columns 4 are provided with inwardly extending mounting plates 5. The support shaft 32 passes through the mounting plate 5 (preferably, the support shaft 32 is segmented and threaded onto the mounting plate 5; alternatively, the support shaft 32 can be welded to the mounting plate 5 or injection molded integrally with it). The abutment roller 31 is rotatably sleeved on the support shaft 32, and the abutment roller 31 includes an upper roller assembly. The upper roller group 311 and the lower roller group 312 are spaced apart and located on opposite sides of the mounting plate 5 to form a guide groove 6 for the shuttle plate to enter. Both the upper roller group 311 and the lower roller group 312 are provided with a conical abutment surface 7 that abuts against the shuttle plate. The conical abutment surfaces 7 of the upper roller group 311 and the lower roller group 312 cooperate to form a figure-eight abutment surface. They are supported between the upper and lower door rings by the support column 4 and the support shaft 32 is installed by the mounting plate 5. The abutment roller 31 can be directly sleeved on the support shaft 32. The guide groove 6 allows the shuttle plate to enter and plays a role in guiding the shuttle and preventing the shuttle plate from moving up and down. The upper roller group 311 and the lower roller group 312 can be used for the shuttle plate to abut against when it moves. The figure-eight abutment surface can increase the contact area with the shuttle plate and also has a certain guiding and anti-movement effect.

[0013] Both the upper roller assembly 311 and the lower roller assembly 312 include a first abutting wheel 81 and a second abutting wheel 82. The first abutting wheel 81 is located near the mounting plate 5 and on opposite sides of the guide groove 6. The second abutting wheel 82 is located outside the first abutting wheel 81, and a conical abutting surface 7 is provided on the second abutting wheel 82. The first abutting wheel 81 can abut against the shuttle plate located in the guide groove 6, thereby allowing the first abutting wheel 81 to rotate and reduce friction. The second abutting wheel 82 can be provided with a conical abutting surface 7, thereby providing a surface for the shuttle plate to abut.

[0014] Bearings 9 are provided at both ends of each second abutment wheel 82 on the support shaft 32. The first abutment wheel 81 is sleeved on the second abutment wheel 82 and rotates synchronously with it. The first abutment wheel 81 covers the bearing 9 at one end of the second abutment wheel 82, and a dust cover 10 is provided on the bearing 9 at the other end of the second abutment wheel 82. The dust cover 10 covers the top and bottom of the support shaft 32, which can prevent dust or dirt from entering the bearing 9, making it more stable during use and increasing its service life.

[0015] A first pull rod 20 is provided on the upper door ring 1 corresponding to the top of the support shaft 32. One end of the first pull rod 20 is attached to the support shaft 32, and the other end is fixed to the upper door ring 1. A second pull rod 30 is provided on the lower door ring 2 corresponding to the bottom of the support shaft 32. One end of the second pull rod 30 is attached to the support shaft 32, and the other end is fixed to the lower door ring 2. Both the first pull rod 20 and the second pull rod 30 are located inside the support shaft 32. Because the shuttle plate is located inside when it is shuttling, there will be a centrifugal force that pushes the second abutment wheel 82 outward. Although the diameter of the support shaft 32 is relatively large, it will still deform after long-term use, affecting the shuttle plate's shuttling. Therefore, the pull rods are used to directly hold both ends of the support shaft 32 to further prevent its deformation, further improve the structural strength, and increase stability.

[0016] One end of the first pull rod 20 that mates with the support shaft 32 is fixed or integrally mounted on the dust cover 10 at the top of the support shaft 32. The other end of the second pull rod 30 that mates with the support shaft 32 is fixed or integrally mounted on the dust cover 10 at the bottom of the support shaft 32. Directly mounting it on the dust cover 10 simplifies the structure and eliminates the need for an additional cover to be fitted onto the support shaft 32, resulting in a more reasonable structural layout.
