Description

Technical Field

[0001] This utility model relates to the field of circular loom technology, specifically a protective mechanism for a circular loom. Background Technology

[0002] A circular loom is an industrial device used for weaving tube fabric. The warp frame of a circular loom has many spindles. Depending on the width of the fabric and the width of the flat yarn, a specified number of warp yarns are used. Most current circular looms are automatic, with multiple yarns fed synchronously into the loom during weaving. Due to the tension of the yarns, uneven yarn tension or quality issues such as dirt or clumps can cause yarn breakage. When a breakage occurs, because of the large number of yarns involved in the weaving process, timely troubleshooting is necessary to prevent continued machine operation and potential equipment damage, which can also affect the quality of the finished product. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a protective mechanism for circular looms, which solves the problem that current circular looms, due to the large number of threads involved, are difficult to quickly locate when a thread breaks, thus affecting equipment lifespan and finished product quality.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: a protective mechanism for a circular loom, comprising a protective net covering the outside of the circular loom, a protective cover for protecting the yarn above the protective net, a plurality of connecting posts connecting the protective net and the protective cover, a turning ring horizontally provided on the connecting posts for the yarn to turn toward the center, and a threading part for the yarn to pass through and be protected outside the turning ring.

[0007] The threading part includes a mounting ring horizontally positioned above the outer side of the steering ring. Several detachable and installable rotating rings are sleeved on the outer side of the mounting ring. A thread loop extending into the steering ring for the thread to pass through is provided on the side of the rotating ring facing the steering ring. A counterweight bar extending horizontally outward is provided on the outer side of the rotating ring opposite to the thread loop.

[0008] Preferably, the rotating ring includes two sets of opposing semi-circular retaining rings. The top of the semi-circular retaining rings is provided with a connecting strip that movably connects the two sets of semi-circular retaining rings. The bottom of one set of semi-circular retaining rings is provided with a movable connecting plate, and the bottom of the other set of semi-circular retaining rings is provided with a connecting plate that fits into the movable connecting plate.

[0009] Preferably, the movable connecting plate includes a fixed plate fixed to the bottom of the semi-circular retaining ring and extending downward, and the two ends of the fixed plate are rotatably connected to rotating sleeve rods that are sleeved with the connecting plate.

[0010] The connecting plate and the fixed plate have protruding strips on their opposite sidewalls that engage with the rotating sleeve rod.

[0011] Preferably, the loop includes a horizontal bar fixedly connected to the side wall of a semi-circular retaining ring facing the steering ring. The horizontal bar extends toward the center of the steering ring and has a hollow ring at its end for the thread to pass through. The hollow ring is oriented perpendicular to the steering ring.

[0012] Preferably, the counterweight bar includes a second horizontal bar fixed to the side wall of a semi-circular retaining ring facing outward, and a counterweight ball is fixedly connected to the outer end of the second horizontal bar. The weight of the counterweight ball is greater than the weight of the loop.

[0013] Preferably, a gap is provided between the protective net and the protective cover to allow the threading part to move.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a protective mechanism for a circular loom, which has the following beneficial effects:

[0016] By setting up a threading section that connects to the thread during transmission, the thread passes through a hollow ring when transported smoothly, keeping multiple threading sections at the same height. When one of the threads breaks, it will dislodge from the ring, and the heavier counterweight at the outer end will droop below the height of the unbroken counterweight, making it easy for staff to quickly detect and preventing damage from continued operation.

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Figure 1-4 In one embodiment of this utility model, a protective mechanism for a circular loom includes a protective net 1 covering the outside of the circular loom. The protective net 1 protects the yarn being pulled into the circular loom. A protective cover 2 is provided above the protective net 1 to protect the yarn. Several connecting posts 3 are provided between the protective net 1 and the protective cover 2 to connect the protective net 1 and the protective cover 2. A gap is provided between the protective net 1 and the protective cover 2 for the yarn threading part 5 to move. A turning ring 4 is horizontally provided on the connecting posts 3 for the yarn to turn towards the center. A yarn threading part 5 is provided on the outside of the turning ring 4 for the yarn to pass through and for protection. In actual operation... The yarn is pulled into the circular loom through the yarn spool holder on the outside of the loom. It first enters the lower part of the circular loom, and then moves upward through the turning ring 4 to the braiding section in the middle of the circular loom for weaving. When the yarn passes through the turning ring 4, it changes from moving vertically upward to moving horizontally towards the braiding section in the middle. When the yarn turns, the worker passes a single yarn through a single threading part 5. When the yarn is running smoothly, multiple threading parts 5 maintain the same height. When a yarn breaks, the threading part 5 will change in time to facilitate the worker to quickly locate the break.

[0026] The threading part 5 includes a mounting ring 51 horizontally positioned above the outer side of the steering ring 4. Several detachable rotating rings 52 are fitted around the outer side of the mounting ring 51. The diameter of the rotating rings 52 is larger than the diameter of the mounting ring 51. On the side of the rotating rings 52 facing the steering ring 4, there is a thread loop 53 extending into the steering ring 4 for the yarn to pass through. On the opposite side of the thread loop 53, there is a counterweight rod 54 extending horizontally outward on the outer side of the rotating ring 52. In actual operation, the yarn that has moved horizontally after passing through the steering ring 4 passes through the thread loop 53. When multiple yarns pass through the thread loop 53 for weaving, the height of the thread loop 53 is consistent, and the height of the counterweight rod 54 at the other end is also consistent. When a straight yarn breaks, this yarn will dislodge from the thread loop 53, causing the height of the thread loop 53 and the counterweight rod 54 to change, thus making it easier for workers to quickly find the location of the broken yarn.

[0027] The rotating ring 52 includes two sets of opposing semi-circular retaining rings 521. The top of each semi-circular retaining ring 521 has a connecting strip 522 that movably connects the two sets of semi-circular retaining rings 521. One set of semi-circular retaining rings 521 has a movable connecting plate 523 at its bottom, and the other set of semi-circular retaining rings 521 has a connecting plate 524 that engages with the movable connecting plate 523 at its bottom. The movable connecting plate 523 includes a fixed plate 5231 fixed to the bottom of the semi-circular retaining rings 521 and extending downwards. Rotating sleeve rods 5232 that engage with the connecting plate 524 are rotatably connected to both ends of the fixed plate 5231. The sidewalls of the connecting plate 524 and the fixed plate 5231 facing opposite directions have protruding strips 5241 that engage with the rotating sleeve rods 5232. In actual operation, the semi-circular retaining rings 521 are flipped open along the connecting strip 522 to open the two sets of semi-circular retaining rings 521, and the rotating ring 52 is fitted onto the outside of the mounting ring 51. Then, along... The connecting bar 522 presses the two sets of semi-circular retaining rings 521 together, so that the fixing plate 5231 contacts the connecting plate 524. Then, the sleeve rod 5232 is manually rotated to move towards the connecting plate 524. The bottom end of the connecting plate 524 is sleeved on the outside of the connecting plate 524, and pressure is applied to make the connecting plate 524 pass through the protruding bar 5241, so that the upper side of the connecting plate 524 and the protruding bar 5241 are engaged, thereby realizing the merging and limiting of the two sets of semi-circular retaining rings 521. When it is necessary to remove the threading part 5, the operator moves the rotating sleeve rod 5232 downward, so that the rotating sleeve rod 5232 contacts the protruding bar 5241. Then, the sleeve rod 5232 is continuously rotated, so that the rotating sleeve rod 5232 is sleeved on the connecting plate 524, thereby separating the two sets of semi-circular retaining rings 521 and thus removing the threading part 5, which is convenient for installing the number of threading parts 5 according to the actual number of threads.

[0028] The thread loop 53 includes a horizontal rod 531 fixedly connected to the side wall of a semi-circular retaining ring 521 facing the steering ring 4. The horizontal rod 531 extends toward the center of the steering ring 4 and has a hollow ring 532 at its end for the thread to pass through. The hollow ring 532 is oriented perpendicularly to the steering ring 4 and its height is the same as that of the steering ring 4. In actual operation, the thread passes through the hollow ring 532 and moves toward the circular loom. Since the direction of the thread movement is horizontal, the height of the hollow ring 532 is consistent with that of the thread. When multiple threads work synchronously, their heights are consistent, thus ensuring that the heights of multiple sets of hollow rings 532 are consistent.

[0029] The counterweight bar 54 includes a second horizontal bar 541 fixed to the side wall of a semi-circular retaining ring 521 facing outward. A counterweight ball 542 is fixedly connected to the outer end of the second horizontal bar 541. The weight of the counterweight ball 542 is greater than the weight of the loop 53. In actual operation, since the height of multiple hollow loops 532 that have passed through the yarn is consistent, the height of the counterweight bar 54 in the opposite direction to the loop 53 is also consistent. When a yarn breakage occurs, the yarn releases the restriction on the height of the hollow loop 532. Since the weight of the counterweight ball 542 is greater than the weight of the loop 53, the counterweight ball 542 hangs down accordingly, making the height of the threaded part 5 of the broken yarn lower than that of other threaded parts 5 that have not broken yarn, making it easier for workers to find.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
