Utility Model Content

[0003] In summary, in order to overcome the deficiencies of the prior art, the utility model provides a shuttle-less wheel suspended circular loom.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a shuttleless wheel suspended circular loom, comprising a shuttle and a ring-shaped frame, the frame comprising an upper door ring, a lower door ring and a ring track arranged between the upper door ring and the lower door ring, the shuttle is arranged in the ring track, the upper end face and the lower end face of the shuttle are respectively provided with gaps between the upper door ring and the lower door ring, the ring track comprises a plurality of connecting brackets distributed in a ring shape and a roller group arranged on the connecting bracket, the connecting bracket comprises an upper connecting column, a lower connecting column and a roller group connecting the upper connecting column and the lower connecting column The transition connecting section is arranged at an angle between the upper connecting column and the lower connecting column, and the roller group includes an upper roller sleeved on the upper connecting column and coaxially arranged with the upper connecting column and a lower roller sleeved on the lower connecting column and coaxially arranged with the lower connecting column. The shuttle is provided with a shuttle back on one side corresponding to the transition connecting section, and a sliding ridge is provided in the middle of the shuttle back. The sliding ridge is detachably connected to the shuttle, and the sliding ridge is provided between the upper and lower rollers. The upper and lower rollers are respectively in rolling contact with the shuttle back, and a shock-absorbing layer is provided between the roller group and the shuttle back.

[0005] By adopting the above technical solution, the shuttle is set to slide in the circular track, so that there is no contact between the shuttle and the upper door ring and the lower door ring, which solves the problem of flat yarn fuzzing, cracking and broken yarn caused by the shuttle wheel rolling the warp yarn during the weaving process of the circular loom that has troubled the plastic weaving industry. The molding quality of the woven bag is improved, and at the same time, the broken yarn fault is avoided, and there is no need to stop the machine for sorting, which greatly improves the production efficiency; and the upper and lower rollers are respectively in rolling contact with the shuttle back. Compared with the existing roller contact with the sliding ridge, the contact area becomes larger, and the wear on the sliding ridge is reduced. At the same time, the existing roller is changed from being parallel to the shuttle back to the roller contacting the shuttle back. The hardness of the shuttle is higher than the sliding ridge, which reduces the centrifugal force of the shuttle on the roller under high-speed operation and extends the service life of the roller group.

[0006] The utility model is further provided with: the connecting bracket includes a mounting shell connected to the upper door ring and the lower door ring, the transition connecting section is connected to the mounting shell, the upper connecting column and the lower connecting column are symmetrically arranged, one end of the upper and lower connecting columns is connected to the transition connecting section, and the other end is open, the length of the upper connecting column is adapted to the upper roller, the upper connecting column is hollow and provided with a connecting channel, the corresponding open end of the connecting channel is provided with an internal thread, the corresponding open end of the upper connecting column is provided with a fastener for limiting the upper roller, and the fastener is detachably connected to the connecting channel.

[0008] The utility model is further configured that: the upper and lower rollers both include rolling bearings, and the rolling bearings are wrapped with elastic shock-absorbing bodies.

[0009] By adopting the above technical solution, when the shock-absorbing layer is set on the roller, it is convenient and quick to replace, reducing the maintenance and replacement costs. At the same time, the shock-absorbing layer is set to reduce the noise during the operation of the shuttle and extend its service life.

[0010] The utility model is further provided with dustproof gaskets at the upper and lower ends of the rolling bearing.

[0011] By adopting the above technical solution, the service life of the rolling bearing is increased and dust is prevented from accumulating and entering the rolling bearing.

[0012] The utility model is further provided with: the diameter of the transition connection section is larger than the diameter of the upper and lower connection columns; a sleeve is provided at the other end of the upper and lower connection columns relative to the transition connection section; the sleeve is sleeved on the upper connection column or the lower connection column and forms a mounting groove for limiting the upper and lower rollers between the transition connection section; the length of the upper and lower rollers is adapted to the spacing between the sleeve and the transition connection section.

[0014] The utility model is further provided with: a shock-absorbing plate is provided on the back of the shuttle, the shock-absorbing plate is in contact with the roller group, and the shock-absorbing plate and the boat shuttle are detachably connected.

[0015] By adopting the above technical solution, the friction between the shuttle boat and the roller is reduced, the noise is reduced, and the service life of the roller and the shuttle boat is extended.

[0016] The utility model is further configured that the angle between the upper connecting column and the lower connecting column is a, 95°<a<180°.

[0017] By adopting the above technical solution, compared with parallel abutment and angle abutment, the abutment force is stronger and the stability is higher, which can avoid the deviation of the shuttle.

[0018] The utility model is further provided with: a mounting groove for mounting a sliding ridge is provided in the middle of the shuttle back; a plurality of connecting holes for connecting with the mounting groove are provided on the sliding ridge; the sliding ridge and the mounting groove are detachably connected by fasteners; the connecting hole is a mounting countersunk hole; the fastener is arranged in the mounting countersunk hole.

[0019] By adopting the above technical solution, the shuttle can be disassembled and easily repaired and replaced without having to scrap the entire shuttle. The cost is low, and the connection holes and fasteners are used to facilitate assembly. The fasteners are set in the mounting countersunk holes to avoid the fasteners protruding from the sliding ridges, avoiding collision between the fasteners and the rollers, and improving stability.
