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 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 shortcomings of the prior art and provide a door ring assembly for a shuttleless circular loom. With this design, 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 shaft can be removed to replace only one of them. It is not necessary to remove the whole machine. Replacement is more convenient and the structure is relatively simple, which can reduce mold opening costs.

[0004] This utility model discloses a gate ring assembly for a shuttleless circular loom, including an upper gate ring, a lower gate ring, support rollers, and a shuttle plate. Several support rollers are spaced apart along the circumferential direction, and these support rollers cooperate to form a shuttle track for the shuttle plate to pass through. The support rollers are characterized by: a first shaft and a second shaft that are separately configured; the top of the first shaft is detachably connected to the upper gate ring, and a first abutting wheel is rotatably fitted onto the bottom of the first shaft; the bottom of the second shaft is detachably connected to the lower gate ring, and a second abutting wheel is rotatably fitted onto the top of the second shaft; the first and second shafts are spaced apart vertically, so that the first and second abutting wheels are spaced apart to form an abutting cavity; the bottom portion of the shuttle plate protrudes outward to form a raised portion, which is located within the abutting cavity, with the upper side of the raised portion abutting against the first abutting wheel and the lower side of the raised portion abutting against the second abutting wheel.

[0005] With the above technical solution and design, 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 shaft can be 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, which can reduce mold opening costs.

[0006] A further feature of this invention is as follows: a first inclined abutment surface is provided on the upper side of the raised portion, a second inclined abutment surface is provided on the first abutment wheel corresponding to the position of the first inclined abutment surface for abutting against it, a third inclined abutment surface is provided on the lower side of the raised portion, and a fourth inclined abutment surface is provided on the second abutment wheel corresponding to the position of the third inclined abutment surface for abutting against it.

[0007] By adopting the above technical solution, this design can prevent the raised part from contacting the first shaft and the second shaft, and facilitate the rotation of the first abutting wheel and the second abutting wheel, thereby reducing slippage and making the shuttle plate move more smoothly.

[0008] A further feature of this invention is that protective sleeves are provided on the upper and lower door rings corresponding to the positions of the first and second abutting wheels, and the protective sleeves include partitions located on opposite sides of the first and second abutting wheels.

[0009] By adopting the above technical solution, it is possible to prevent the warp threads from getting caught on the first and second abutting wheels.

[0010] A further feature of this invention is that it includes a first threaded sleeve and a second threaded sleeve, with the top of the first shaft locked to the upper door ring by the first threaded sleeve and the bottom of the second shaft locked to the lower door ring by the second threaded sleeve.

[0011] Using the above technical solution, the corresponding shaft can be removed when the corresponding screw sleeve is removed, making maintenance and replacement more convenient.

[0012] A further feature of this invention is that anti-slip sleeves are fitted on both the first and second abutting wheels, and the second and fourth inclined abutting surfaces are provided on the corresponding anti-slip sleeves.

[0013] By adopting the above technical solution, slippage during shuttle rotation can be further prevented, thus increasing its stability. Attached Figure Description
