Description

Technical Field

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

[0002] The circular loom gate assembly 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. Abutment rollers for abutting the shuttle plate are rotatably sleeved on the support rollers. However, the abutment rollers currently on the market do not have supporting force in the middle, so they are prone to deformation after long-term use. 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. By setting a support plate in the middle of the support roller, the structural rigidity is further increased, the deformation of the support roller is prevented, and the service life of the support roller is increased.

[0004] This utility model discloses a door ring assembly for a shuttleless circular loom, including an upper door ring, a lower door 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. Each support roller includes an abutment roller and a support shaft. The characteristic feature is that support rods are provided between the upper and lower door rings corresponding to the support roller positions. One end of each support rod is fixedly connected to the upper door ring, and the other end is fixedly connected to the lower door ring. A support plate extending inwards is provided in the middle of each support rod. The support shaft passes through the support plate, with its top end passing through and fixed to the upper door ring, and its bottom end passing through and fixed to the lower door ring. The abutment rollers are rotatably sleeved on the support shaft and are located on the upper and lower sides of the support plate, respectively.

[0005] A further feature of this invention is that the outer surface of the abutting roller is tapered, with the smaller end facing the support plate, thereby causing the abutting rollers on the same support shaft to form a V-shaped abutting surface.

[0006] A further feature of this invention is that the inner side of the support plate is provided with an extension block, a brake component is sleeved on the extension block, the shuttle plate is provided with a clearance groove, the extension block is inserted into the clearance groove, and the brake component is suspended in the clearance groove.

[0007] A further feature of this invention is that the support rod is located outside the upper and lower door rings, and the support rod is fixed to the upper and lower door rings by a fastener, with the support rods spaced apart along the circumferential direction, and a wire-threading hole is formed between two adjacent support rods.

[0008] The beneficial effects of this utility model are as follows: by setting a support plate in the middle of the support roller, the structural rigidity is further increased, the support roller is prevented from deforming, the service life of the support roller is increased, and the main supporting force of the upper and lower door rings is further distributed by the support rod, which further prevents the support shaft from deforming.

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 door ring assembly for a shuttleless circular loom, including an upper door ring 1, a lower door ring 2, support rollers 3, and a shuttle plate 4. 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 4 to pass through. Each support roller 3 includes an abutment roller 31 and a support shaft 32. Preferably, the abutment roller 31 is fitted onto the support shaft using a bearing. In this embodiment, support rods 5 are provided between the upper door ring 1 and the lower door ring 2 at positions corresponding to the support rollers 3. One end of each support rod 5 is fixedly connected to the upper door ring 1, and the other end is fixedly connected to the lower door ring 2. On ring 2, and in the middle of the support rod 5, there is an inwardly extending support plate 6. The support shaft 32 passes through the support plate 6, and the top of the support shaft 32 passes through and is fixed to the upper door ring 1. The bottom of the support shaft 32 passes through and is fixed to the lower door ring 2. The abutting roller 31 is rotated and sleeved on the support shaft 32 and is located on the upper and lower sides of the support plate 6 respectively. By setting the support plate 6 in the middle of the support roller 3, the structural rigidity is further increased, the support roller 3 is prevented from deforming, and the service life of the support roller 3 is increased. The upper door ring 1 and the lower door ring 2 are further supported by the support rod 5, which further prevents the support shaft 32 from deforming.

[0012] The outer surface of the abutting roller 31 is tapered, with the smaller end facing the support plate 6, causing the abutting roller 31 on the same support shaft 32 to form a V-shaped abutting surface, so that the shuttle plate 4 abuts against the V-shaped abutting surface when it shuttles, which has a certain guiding and supporting function.

[0013] The inner side of the support plate 6 is provided with an extension block 7, and a brake component 8 is sleeved on the extension block 7. The shuttle plate 4 is provided with a clearance groove 41. The extension block 7 is inserted into the clearance groove 41, and the brake component 8 is suspended in the clearance groove 41. When the shuttle plate 4 shuttles normally, the shuttle plate 4 abuts against the V-shaped abutment surface. The brake component 8 is separated from the clearance groove 41 and does not contact it. When the shuttle plate 4 is tilted, the inner wall of the clearance groove 41 will abut against the brake component 8. The brake component 8 is preferably made of rubber. By rubbing against the shuttle plate 4, the shuttle plate 4 can stop more quickly.

[0014] The support rod 5 is located on the outside of the upper door ring 1 and the lower door ring 2, and the support rod 5 is fixed to the upper door ring 1 and the lower door ring 2 by the fixing member 9. The support rod 5 is distributed at intervals along the circumference (the fixing member 9 is preferably a bolt or screw). A threading hole is formed between two adjacent support rods 5. The support rod 5 is installed from the outside, which makes it easy to observe and operate during installation. In addition, it can also separate the warp threads while providing support, which has multiple benefits.
