Description

Technical Field

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

[0002] Current plastic circular looms typically use a shuttle that runs directly on a track formed by upper and lower gate rings. Alternatively, existing suspended circular looms may have a frame including a circular track with multiple connecting brackets. However, the connection between these brackets and the upper and lower gate rings usually involves drilling holes around the gate rings. The connecting brackets are then fixed to nuts at both ends of a shaft passing through through holes. Due to the large diameter of the gate rings and the numerous through holes, ensuring that the connecting brackets can be assembled into a circular track with zero roundness is challenging. Circumferential drilling makes it impossible to adjust the position of the connecting brackets, resulting in low tolerance and inconvenience. Furthermore, the existing connection between rollers and connecting brackets is unstable, structurally complex, and difficult to assemble, which are also problems that urgently need to be solved. Utility Model Content

[0003] In summary, to overcome the shortcomings of the prior art, this utility model provides a door ring assembly for a shuttleless suspension circular loom.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a door ring assembly for a shuttleless suspended circular loom, comprising an upper door ring, a lower door ring, and an annular track disposed between the upper and lower door rings. The annular track includes multiple connecting brackets arranged in a ring and a roller assembly disposed on the connecting brackets. The connecting brackets include a mounting shell connected to the upper and lower door rings and a mounting frame for mounting the roller assembly. The mounting frame is detachably connected to the mounting shell. The mounting frame includes an upper connecting column, a lower connecting column, and a connecting part connecting the upper and lower connecting columns. The roller assembly includes an upper roller sleeved on the upper connecting column and coaxially disposed with the upper connecting column, and a lower roller sleeved on the lower connecting column and coaxially disposed with the lower connecting column. The mounting shell has L-shaped mounting recesses symmetrically disposed at its upper and lower ends. The mounting recesses engage with the outer circumferential surface of the corresponding upper or lower door ring. The back of the mounting shell has assembly holes for detachable connection with the upper and lower door rings at positions corresponding to the two mounting recesses.

[0005] By adopting the above technical solution, the connecting brackets are set on the outside of the upper and lower door rings, so that the connecting brackets are distributed along the outer circumference of the upper and lower door rings. There is no need to locate the position of each round hole, forming a circular track with zero roundness. The back of the mounting shell is provided with assembly holes, and assembly is carried out from the outside. It is convenient to quickly replace and assemble individual connecting brackets without disassembling the whole machine. The entire upper door ring can be removed for replacement, which is convenient for maintenance. The L-shaped mounting recess abuts against the upper and lower door rings, further positioning the distance between the upper and lower door rings, which is convenient for assembly and has high stability.

[0006] The present invention further includes: adjustment holes for adjusting the position of the mounting shell are provided on both sides of the assembly hole, and the adjustment holes are located at opposite corners of the mounting shell.

[0007] By adopting the above technical solution and setting adjustment holes, since the circular track is composed of multiple connecting brackets and roller groups, the height of the assembled track must be consistent, which requires high precision in assembly. In actual production and use, the position of the connecting brackets (the height difference is generally a few micrometers) can be adjusted by adjusting the tightness of the adjustment holes, which can reduce the high precision requirements for the quality of the brackets and make it more applicable.

[0008] The present invention further comprises: the upper connecting column and the lower connecting column are symmetrically arranged, one end of the upper and lower connecting columns are connected to the connecting part, and the other end is open. The upper and lower connecting columns are provided with dust covers for limiting the upper and lower rollers at the corresponding open ends. The dust covers are detachably connected to the mounting shell.

[0009] By adopting the above technical solution, the dust cover can serve both as a dust cover and as a limiter for the upper and lower rollers. It is a dual-purpose device with a simple structure, high stability, and prevents dust from accumulating and entering the upper and lower rollers, thus improving the service life of the rollers.

[0010] The present invention further includes: both the upper and lower rollers include rolling bearings, and the rolling bearings are wrapped with elastic shock absorbers.

[0011] By adopting the above technical solutions, it is possible to facilitate quick replacement, reduce maintenance and replacement costs, reduce noise during shuttle operation, and extend service life.

[0012] The present invention further comprises: the dust cover having an installation through hole adapted to the upper or lower connecting post; the side of the dust cover corresponding to the rolling bearing having a first protrusion abutting against the rolling bearing; the outer diameter of the first protrusion being smaller than the outer diameter of the rolling bearing; the dust cover being sleeved on the upper or lower connecting post and abutting against the rolling bearing; and the side of the dust cover corresponding to the rolling bearing also having a second protrusion adapted to the inner diameter of the elastic damping body.

[0013] By adopting the above technical solution, the dust cover is sleeved on the upper or lower connecting column and abuts against the rolling bearing, facilitating quick positioning and assembly of the dust cover. Then, a first protrusion is provided to abut against the rolling bearing, facilitating quick positioning of the dust cover and aligning the second connecting hole with the second mounting hole. The dust cover is then fixed by engaging fasteners through the second connecting hole, further preventing rotation. The second protrusion further improves the tightness of the connection between the dust cover and the elastic damping body, preventing dust from entering the rolling bearing through gaps and improving the service life of the rolling bearing.

[0014] The present invention further includes: the open ends of the upper and lower connecting columns are provided with fasteners for fixing the dust cover, and the open ends of the upper and lower connecting columns are hollow and provided with internal threads that are compatible with the fasteners.

[0015] By adopting the above technical solution, the (upper or lower) roller is inserted through the opening of the (upper or lower) connecting column, and then the dust cover is installed. The dust cover and the (upper or lower) roller are limited by tightening the fasteners, so that the (upper or lower) roller can rotate stably at this height. The structure is simple, easy to assemble, and highly stable.

[0016] The present invention further comprises: a working cavity for accommodating the upper and lower rollers respectively on the front side of the mounting shell; a mounting part for fixing the connecting part between the two working cavities; a mounting groove adapted to the connecting part on the mounting part; the diameter of the upper and lower connecting columns is smaller than the diameter of the connecting part; a dustproof gasket for abutting against the rolling bearing is provided at one end of the upper and lower rollers corresponding to the connecting part; the two ends of the connecting part protrude from the upper and lower end faces of the mounting part respectively; and a gap is provided between the dustproof gasket and the upper or lower end face of the mounting part.

[0017] By adopting the above technical solution, a gap is created between the upper and lower rollers and the mounting part, making the rotation of the upper and lower rollers more stable and smooth, and reducing friction.

[0018] The present invention further comprises: the outer diameter of the dustproof pad is adapted to the inner diameter of the elastic shock absorber, and the elastic shock absorber is sleeved on the outside of the dustproof pad.

[0019] By adopting the above technical solution, the dustproof pad is set inside the elastic damping body, which further enhances the dustproof function at both ends of the elastic damping body.

[0020] The present invention further comprises: a first connecting hole for detachable connection with the mounting shell on the connecting part; a second connecting hole for detachable connection with the mounting shell on the back of the dust cover; a first mounting hole for mounting fasteners on the back of the mounting shell corresponding to the third connecting hole; and a second mounting hole for mounting fasteners on the back of the mounting shell corresponding to the second connecting hole.

[0021] By adopting the above technical solution, the assembly is carried out from the outer periphery of the door ring, and the mounting bracket and dust cover are fixedly connected by screwing in fasteners from the back of the mounting shell. The three-point connection has higher stability. The back assembly method makes assembly easier and maintenance and replacement more convenient, while not affecting the rotation of the upper and lower rollers.

[0022] This utility model further comprises: a working cavity for accommodating the upper and lower rollers and a mounting groove for fixing the mounting bracket on the front side of the mounting shell; a mounting component for fixing the connecting part is provided in the mounting groove; a mounting groove adapted to the connecting part is provided on the side of the mounting component opposite to the mounting groove; a second connecting hole for detachable connection with the mounting shell is provided on the back side of the dust cover; a third connecting hole for detachable connection with the mounting shell is provided on the mounting component; a first mounting hole for installing fasteners is provided on the back side of the mounting shell corresponding to the third connecting hole; and a second mounting hole for installing fasteners is provided on the back side of the mounting shell corresponding to the second connecting hole.

[0023] By adopting the above technical solution, the mounting bracket is first clamped between the mounting component and the mounting slot. Then, fasteners are installed from the back through the first connecting hole and the first mounting hole, so that the mounting component and the mounting slot are connected by the fasteners, thereby fixing the mounting bracket. The structure is simple and convenient for processing and assembly.
