The support rollers are arranged on the opposite sides of the abutting rollers, and the support rollers are placed in the guiding groove, which can not only prevent the support rollers from contacting the warp threads, but also prevent the abutting rollers from contacting the warp threads. The structural layout is more reasonable, and wire jamming can be further prevented.

[0004] The utility model discloses a circular loom door ring assembly, which includes an upper door ring, a lower door ring, support rollers and a shuttle plate. A number of support rollers are arranged at intervals along the circumferential direction, and the number of support rollers cooperate to form a shuttle track for the shuttle plate to shuttle through. An abutting roller for abutting against the shuttle plate is rotatably sleeved on the support roller. The characteristics are that: Two groups of support rollers are arranged at intervals one above the other on the inner side of the support roller, the abutting roller is arranged between the two groups of support rollers, a convex rib is arranged on the shuttle plate corresponding to the position of the abutting roller, the outer side of the convex rib abuts against the abutting roller, the upper and lower sides of the convex rib respectively abut against the corresponding support rollers. The support roller on the upper side is the upper support roller, and the support roller on the lower side is the lower support roller. A first shielding piece is arranged on the top of the shuttle plate corresponding to the upper support roller, and a second shielding piece is arranged on the bottom of the shuttle plate corresponding to the lower support roller.

[0005] With the above technical solution, during use, the shuttle plate shuttles on the shuttle track. At this time, the upper support roller and the lower support roller on the corresponding support roller can clamp and support the convex rib of the shuttle plate. At the same time, the corresponding abutting roller abuts against the outer side of the convex rib. When the shuttle plate shuttles, the abutting roller can rotate relatively, thereby reducing the friction. At the same time, the first shielding piece shields the top of the upper support roller, and the second shielding piece shields the bottom of the lower support roller, thereby preventing the warp threads from contacting the upper support roller and the lower support roller, making it more stable during use and preventing wire jamming.

Therefore, it should not be construed as a limitation to the present utility model.

[0018] The present disclosure relates to a circular loom door ring assembly, including an upper door ring 1, a lower door ring 2, support rollers 3, and a shuttle plate 4. A plurality of support rollers 3 are arranged at intervals along the circumferential direction. The plurality of support rollers 3 cooperate to form a shuttle track for the shuttle plate 4 to shuttle through. A contact roller 6 for abutting against the shuttle plate 4 is rotatably sleeved on the support roller 3. In the embodiment of the present utility model, two groups of support rollers 5 are arranged at intervals, one above the other, on the inner side of the support roller 3. The contact roller 6 is arranged between the two groups of support rollers 5. A rib 41 is arranged on the shuttle plate 4 at the position corresponding to the contact roller 6. The outer side of the rib 41 abuts against the contact roller 6, and the upper and lower sides of the rib 41 respectively abut against the corresponding support rollers 5. The support roller 51 located on the upper side is the upper support roller 51, and the support roller 52 located on the lower side is the lower support roller 52. A first shielding piece 42 is arranged on the top of the shuttle plate 4 corresponding to the upper support roller 51, and a second shielding piece 43 is arranged on the bottom of the shuttle plate 4 corresponding to the lower support roller 52.

[0019] With the above technical solution, during use, the shuttle plate 4 shuttles through the shuttle track. At this time, the upper support roller 51 and the lower support roller 52 on the corresponding support roller 3 can clamp and support the rib 41 of the shuttle plate 4. At the same time, the corresponding contact roller 6 abuts against the outer side of the rib 41. When the shuttle plate 4 shuttles, the contact roller 6 can rotate relatively, thereby reducing the friction force. At the same time, the first shielding piece 42 shields the top of the upper support roller 51, and the second shielding piece 43 shields the bottom of the lower support roller 52, thereby preventing the warp yarn from contacting the upper support roller 51 and the lower support roller 52, making it more stable during use and preventing wire jamming. The support roller and the contact roller are most preferably installed using bearings, which can reduce the friction force. The specific installation method belongs to the prior art and will not be described in detail herein.

[0020] There is a gap between the inner sides of the upper support roller 51 and the lower support roller 52 and the shuttle plate 4, which can prevent friction between the inner sides of the upper support roller 51 and the lower support roller 52 and the shuttle plate 4, making the shuttle of the shuttle plate 4 smoother.

[0021] There is a gap between the top of the upper support roller 51 and the first shielding piece 42, and a gap between the bottom of the lower support roller 52 and the second shielding piece 43, which can further reduce the contact area and thus reduce the friction force.

[0022] An installation base 71 is arranged on the support roller 3 corresponding to the positions of the upper support roller 51 and the lower support roller 52. An installation plane 72 is arranged on the installation base 71. The upper support roller 51 and the lower support roller 52 are arranged on the installation plane 72. The installation of the upper support roller 51 and the lower support roller 52 can be facilitated through the installation base 71 and the installation plane 72, making them more stable during operation.
