Description

Technical Field

[0001] This utility model relates to the field of circular loom technology, specifically a tension adjustment device for circular looms. Background Technology

[0002] A circular loom is a shuttle-type loom specifically designed for weaving tubular fabrics. It gets its name from the circular arrangement of its weaving mechanism. Its working principle is as follows: warp yarns are unwound from the central bobbin, and weft yarns are introduced radially by the shuttle. The warp and weft yarns interweave on a circular track to form a tubular fabric, which is then drawn and cut to form packaged fabric. Main products include woven bags, container bags, geotextiles, and shade nets, widely used in packaging, building materials, and agriculture. Circular looms typically operate at speeds of 40–120 rpm and can achieve widths exceeding 3000 mm. They are characterized by high output, low cost, and strong adaptability, making them the mainstream equipment for woven bag production.

[0003] When adjusting the yarn tension on a circular loom, the operator needs to use one hand to hold a testing instrument to check the yarn tension and the other hand to operate a hex wrench for adjustment. In traditional circular loom tension adjustment structures, the adjusting screw is usually located on top of the adjusting seat. The accumulation of dust on the top of the adjusting seat, combined with the screw's unusual position, makes it inconvenient for operators to use the hex wrench. If the hex wrench comes loose and falls into the machine, it can easily cause direct malfunctions. Furthermore, the micro-vibrations of the loom frame during operation can easily loosen the adjusting screw, requiring frequent checks and adjustments by the operator, resulting in high labor intensity. Therefore, to address these problems, a tension adjustment device for circular looms is proposed. Utility Model Content

[0006] The adjustment mechanism includes an adjustment block and a mounting base. The mounting base is fixedly installed on the outside of the frame. The adjustment block is slidably connected to one side of the mounting base via a slide groove. A screw is rotatably connected to the inside of the slide groove. One end of the screw is threaded to the inside of the adjustment block. A wire frame is fixedly installed on one side of the adjustment block. An assembly cavity is opened on the inside of the mounting base. A second rotating rod is rotatably connected to the inside of the assembly cavity. A first bevel gear is fixedly installed at the end of the second rotating rod. A mounting shell is fixedly installed on the top of the mounting base. A first rotating rod is rotatably connected to the inside of the mounting shell. A rotating block is fixedly installed at one end of the first rotating rod. A second bevel gear is fixedly installed at one end of both the first rotating rod and the screw. The second bevel gear at one end of the screw and the first bevel gear at one end of the second rotating rod are meshed together. The first bevel gear at the other end of the second rotating rod is meshed with the second bevel gear at one end of the first rotating rod. A limiting mechanism is provided on the outside of the mounting shell.

[0007] Preferably, a limiting block is symmetrically fixedly installed on one side of the adjusting block, and a limiting groove is formed on the inner side of the sliding groove. The limiting block and the limiting groove are slidably connected.

[0008] Preferably, the limiting mechanism includes a pusher, which is slidably connected to one end of the mounting shell. A square hole is provided on the inner side of the pusher. Blocks are fixedly installed on both sides of the mounting shell. A spring is symmetrically fixedly installed on one side of each block. The other end of the spring is fixedly installed to the inner wall of the square hole.

[0013] The advantages of this utility model are:

[0014] 1. This utility model improves the adjustment structure of a traditional circular loom, eliminating the need for tools when adjusting tension. Simply operate the rotating block to engage the second bevel gear on the first rotating rod with the first bevel gear on the second rotating rod. Simultaneously, the first bevel gear at the lower end of the second rotating rod engages with the second bevel gear at one end of the screw, allowing the screw to rotate within the groove. The rotation of the screw causes the adjusting block connected by the outer thread to slide, thereby pulling the yarn on the wire frame to adjust the tension. This greatly facilitates operation and use by the workers.

[0015] 2. This utility model, based on the adjustment mechanism, utilizes a pusher that slides on the mounting shell, while simultaneously employing a spring added between the block and the square hole. This allows the first toothed ring on one side of the pusher to insert into the second toothed ring on the rotating block, thus preventing the first rotating rod from loosening due to frame vibration and resulting in poor tension. By setting a positioning mechanism on the pusher, when operating the rotating block, it is only necessary to use the knob to pull the connecting frame, causing it to separate the first and second toothed rings on the pusher. Then, by rotating the knob, one end of the hanging rod at the rotating shaft is hooked into the guide positioning rod, thereby facilitating the limiting of the pusher's position.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0025] Example 1

[0026] This application discloses a tension adjusting device for a circular loom. (Refer to...) Figures 1-5 A tension adjustment device for a circular loom includes a frame 1, and an adjustment mechanism 3 is provided on the outer side of the frame 1;

[0027] The adjustment mechanism 3 includes an adjustment block 301 and a mounting base 304. The mounting base 304 is fixedly installed on the outside of the frame 1. The adjustment block 301 is slidably connected to one side of the mounting base 304 via a slide groove 302. A screw 303 is rotatably connected to the inside of the slide groove 302. One end of the screw 303 is threaded to the inside of the adjustment block 301. A wire frame 2 is fixedly installed on one side of the adjustment block 301. An assembly cavity 3010 is opened on the inside of the mounting base 304. A second rotating rod 308 is rotatably connected to the inside of the assembly cavity 3010. A first bevel gear 309 is fixedly installed at the ends of the second rotating rod 308. A mounting shell 305 is fixedly installed on the top of the mounting base 304. A first rotating rod 307 is rotatably connected to the inside of the mounting shell 305. A rotating block 306 is fixedly installed at one end of the first rotating rod 307. A rotating block 306 is fixedly installed at one end of both the first rotating rod 307 and the screw 303. The second bevel gear 3011 is meshed with the first bevel gear 309 at one end of the screw 303 and the first bevel gear 309 at one end of the second rotating rod 308. The first bevel gear 309 at the other end of the second rotating rod 308 is meshed with the second bevel gear 3011 at one end of the first rotating rod 307. A limiting mechanism 4 is provided on the outer side of the mounting housing 305. By rotating the rotating block 306, the second bevel gear 3011 on the first rotating rod 307 meshes with the first bevel gear 309 on the second rotating rod 308. At the same time, the first bevel gear 309 at the lower end of the second rotating rod 308 meshes with the second bevel gear 3011 at one end of the screw 303, so that the screw 303 can rotate in the sliding groove 302. The rotation of the screw 303 causes the adjusting block 301 connected by the outer thread to slide, thereby facilitating the tension adjustment of the wire body of the wire frame 2 on the adjusting block 301.

[0028] Reference Figure 2 A limiting block 6 is symmetrically fixedly installed on one side of the adjusting block 301, and a limiting groove 5 is opened on the inner side of the slide 302. The limiting block 6 and the limiting groove 5 are slidably connected. By allowing the limiting block 6 on the adjusting block 301 to slide in the limiting groove 5 at the slide 302, the adjusting block 301 can be prevented from slipping out of the slide 302.

[0029] Example 2

[0030] Reference Figure 4The limiting mechanism 4 includes a pusher 403, which is slidably connected to one end of the mounting shell 305. A square hole 404 is provided on the inner side of the pusher 403. Square blocks 405 are fixedly installed on both sides of the mounting shell 305. Springs 406 are symmetrically fixedly installed on one side of each block 405. The other end of each spring 406 is fixedly installed to the inner wall of the square hole 404. A first toothed ring 401 is fixedly installed on one side of the pusher 403, and a second toothed ring 402 is fixedly installed on one side of the rotating block 306. The first toothed ring 401 and the second toothed ring... The toothed part of 402 is a plug-in part. The top of the pusher 403 is provided with a positioning mechanism 9. By using the pusher 403 to slide on the mounting shell 305, and with the spring 406 added between the block 405 and the square hole 404, the first toothed ring 401 on one side of the pusher 403 is inserted into the second toothed ring 402 on the rotating block 306. This can prevent the frame 1 from vibrating and causing the first rotating rod 307 to loosen, thus affecting the stability after the tension adjustment of the line. One end of the first rotating rod 307 passes through the pusher 403 and the first toothed ring 401.

[0031] Reference Figure 4 and Figure 5 The positioning mechanism 9 includes a connecting frame 901, which is fixedly installed at the ends of the connecting frame 901 and the push frame 403. A through hole 902 is opened on the inner side of the connecting frame 901, and a rotating shaft 903 is rotatably connected to the inner side of the through hole 902. A knob 904 is fixedly installed at the other end of the rotating shaft 903, and a hanging rod 905 is fixedly installed on the outer side of the rotating shaft 903. A positioning rod 906 is fixedly installed on the top of the mounting shell 305. The other end of the hanging rod 905 is hooked to the positioning rod 906. When operating the rotating block 306, the connecting frame 901 is pulled by the knob 904, which causes the first toothed ring 401 and the second toothed ring 402 on the push frame 403 to separate. Then, the knob 904 is rotated so that one end of the hanging rod 905 at the rotating shaft 903 is hooked into the guide positioning rod 906, which can limit the position of the push frame 403.

[0032] Reference Figure 5Guide rails 10 are fixedly installed on both sides of the mounting shell 305. The pusher 403 and the guide rails 10 are slidably connected. A groove 8 is symmetrically opened on one side of the inner wall of the square hole 404. The end of the spring 406 away from the block 405 is fixedly installed with the groove 8. A guide rod 7 is fixedly installed on the inner side of the groove 8. One end of the guide rod 7 passes through the middle of the spring 406, and the other end of the guide rod 7 slides through the block 405. A hanging groove 11 is opened at one end of the hanging rod 905. One end of the hanging rod 905 is connected to the positioning rod 906 through the hanging groove 11. The guide rail 10 on the 5 allows the pusher 403 to slide horizontally at one end of the mounting shell 305. The spring 406 is installed through the slot 8 at the square hole 404, which can limit the spring 406 externally. One end of the guide rod 7 passes through the middle of the spring 406, which can limit the spring 406 internally, thereby ensuring the stability and service life of the spring 406. The hanging groove 11 at one end of the hanging rod 905 makes it easy for the knob 904 to be pulled to an appropriate position, and then the pusher 403 is limited by hanging the hanging rod 905 at the pivot 903 on the positioning rod 906.

[0033] Working principle: During adjustment, firstly, when operating the rotary block 306, the connecting frame 901 is pulled by the knob 904, causing it to separate the first gear ring 401 and the second gear ring 402 on the push frame 403. Then, the knob 904 is rotated so that one end of the hanging rod 905 on the rotating shaft 903 is engaged with the guide positioning rod 906, which limits the position of the push frame 403, causing the first gear ring 401 and the second gear ring 402 to separate. Subsequently, by rotating the rotary block 306, the second bevel gear 3011 on the first rotating rod 307 meshes with the first bevel gear 309 on the second rotating rod 308, and at the same time, the second rotating rod 308 lowers... The first bevel gear 309 at one end meshes with the second bevel gear 3011 at one end of the screw 303, allowing the screw 303 to rotate within the slide groove 302. The rotation of the screw 303 causes the adjusting block 301 connected by the outer thread to slide, thereby adjusting the tension of the wire frame 2 on the adjusting block 301. After adjustment, the knob 904 is operated, causing the hanging rod 905 to disengage from the positioning rod 906. In conjunction with the spring 406 added between the square block 405 and the square hole 404, the first toothed ring 401 on one side of the push frame 403 is inserted into the second toothed ring 402 on the rotating block 306, thus limiting the position of the rotating block 306.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
