Description

Technical Field

[0001] This utility model relates to the field of woven bag production technology, specifically to a warp and weft tension balance adjuster in the woven bag production process. Background Technology

[0002] In the production of woven bags, the tension control of the warp and weft threads plays a decisive role in the quality of the bags. An imbalance in warp and weft tension can lead to problems such as dimensional deviations, uneven surfaces, and inconsistent strength.

[0003] Existing tension adjustment devices typically wrap a rubber layer around the rotating rod to increase friction between the rod and the material. However, the rubber layer is prone to accumulating impurities, and after prolonged use, its friction decreases, leading to slippage and consequently reducing the accuracy of tension adjustment. Utility Model Content

[0004] To address the problem of slippage caused by reduced friction due to impurities adhering to the rubber layer, resulting in inaccurate tension adjustment, this utility model aims to provide a warp and weft tension balance adjuster for woven bag production.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a warp and weft tension balance regulator in the woven bag production process, including a processing table and tension sensors. Symmetrically distributed support plates are fixedly mounted on the upper surface of the processing table. Tension sensors are symmetrically distributed and rotatably mounted on opposite sides of the support plates. The tension sensors convert tension signals into electrical signals by strain gauges deforming under force. Symmetrically distributed rotating rods are rotatably mounted on opposite sides of the support plates. A cleaning assembly is provided on the support plates. A deceleration assembly is provided on the outer side of the support plates. The cleaning assembly includes an adsorption roller. Symmetrically distributed grooves are opened on the outer side of the support plates. A slider is slidably mounted inside the grooves. The two ends of the adsorption roller are rotatably mounted on opposite sides of two sliders. A symmetrically distributed fixing plate is fixedly mounted on the outer side of one of the support plates. A threaded rod is rotatably mounted on the opposite side of the fixing plate. A connecting plate is threaded onto the outer side of the threaded rod. One end of the connecting plate is fixedly connected to one side of the slider. A third motor is fixedly mounted on the slider away from the connecting plate. The output shaft of the third motor drives a component fixedly connected to one end of the adsorption roller. A connecting rod is fixedly provided at one end of the threaded rod opposite to the connecting rod. A limiting plate is fixedly sleeved on the outside of the connecting rod. One side of the limiting plate is in contact with the end of the threaded rod near the connecting rod. The connecting rod can drive the two threaded rods to rotate synchronously. The limiting plate can limit the movement of the connecting plate. Symmetrically distributed guide rods are fixedly provided inside the slide groove. One end of the guide rod moves through the slider. The guide rod can keep the slider moving stably. Symmetrically distributed connecting shafts rotate through the support plate near the fixed plate. One end of the connecting shaft is fixedly connected to one end of the rotating rod. Gears are fixedly sleeved on the outside of the connecting shaft. The outer sides of the two gears mesh with each other. The connecting shaft can drive the rotating rod to rotate. The gears can drive the rotating rod to rotate in the opposite direction. A second motor is fixedly provided on the upper surface of the fixed plate. The end of the output shaft of the second motor is fixedly connected to the top of one of the threaded rods. The second motor can provide power for the rotation of the threaded rod. The outside of the rotating rod is wrapped with a rubber ring. The rubber ring can increase the friction between the rotating rod and the woven bag. The threads of the two threaded rods are opposite in direction, which can drive the two connecting plates to move in opposite directions.

[0006] Preferably, the deceleration assembly includes a housing, which is fixedly mounted on one side of a support plate. A worm gear is rotatably mounted inside the housing, and a worm wheel meshes with the outer side of the worm gear. A rotating shaft is fixedly passed through the middle of the worm wheel. One end of the rotating shaft is rotatably mounted on the inner wall of the housing, and the end of the rotating shaft away from the inner wall of the housing passes through the support plate and is fixedly connected to one end of one of the rotating rods. A first motor is fixedly mounted on the outer side of the housing, and the end of the output shaft of the first motor is fixedly connected to one end of the worm gear.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. The connecting rod drives two threaded rods to rotate synchronously. The threaded rods drive the connecting plate to move in opposite directions. The connecting plate drives the slider to move in the groove. The slider drives the adsorption roller to fit against the outside of the rotating rod, so that the adsorption roller adsorbs the impurities on the outside of the rotating rod. This can prevent the rotating rod from slipping due to the adsorption of impurities, thereby improving the accuracy of adjustment.

[0009] 2. The first motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate at a reduced speed. The worm wheel then drives the rotating shaft to rotate at a reduced speed. This avoids the situation where the speed is adjusted too high, thus making it easier to control the rotating rod. Attached Figure Description

A cleaning assembly 2 is provided on the support plates 3, and a deceleration assembly 6 is provided on the outer side of the support plates 3. The cleaning assembly 2 includes an adsorption roller 21.

The two ends of 21 are rotatably mounted on opposite sides of two sliders 23. A symmetrically distributed fixing plate 25 is fixedly mounted on the outer side of one of the support plates 3. A threaded rod 26 is rotatably mounted on the opposite side of the fixing plate 25. A connecting plate 24 is threaded onto the outer side of the threaded rod 26. One end of the connecting plate 24 is fixedly connected to one side of the slider 23. A third motor 211 is fixedly mounted on the slider 23 away from the connecting plate 24. The output shaft of the third motor 211 drives one end of the adsorption roller 21 to rotate synchronously. The threaded rod 26 drives the connecting plate 24 to move in opposite directions. The connecting plate 24 drives the slider 23 to move within the groove 22. The slider 23 drives the adsorption roller 21 and the outer side of the rotating rod 4 to move. The adhesive roller 21 adheres to the outer side of the rotating rod 4, making it easy to clean the impurities from the rotating rod 4. A connecting rod 28 is fixedly provided at one end of the threaded rod 26, and a limiting plate 29 is fixedly sleeved on the outer side of the connecting rod 28. One side of the limiting plate 29 is in contact with the end of the threaded rod 26 near the connecting rod 28. The connecting rod 28 can drive the two threaded rods 26 to rotate synchronously, and the limiting plate 29 can limit the connecting plate 24. Symmetrically distributed guide rods 27 are fixedly provided inside the slide groove 22. One end of the guide rod 27 moves through the slider 23, and the guide rod 27 can keep the slider 23 moving stably. Symmetrically distributed connecting rods are rotatably passed through the support plate 3 near the fixed plate 25. Shaft 7, one end of which is fixedly connected to one end of rotating rod 4. Gear 8 is fixedly sleeved on the outer side of connecting shaft 7. The outer sides of the two gears 8 mesh with each other. The connecting shaft 7 can drive rotating rod 4 to rotate, and the gear 8 can drive rotating rod 4 to rotate in the opposite direction. A second motor 210 is fixedly mounted on the upper surface of fixed plate 25. The end of the output shaft of the second motor 210 is fixedly connected to the top of one of the threaded rods 26. The second motor 210 can provide power to rotate threaded rod 26. The outer side of rotating rod 4 is wrapped with rubber ring 9. The rubber ring 9 can increase the friction between the rod and the woven bag. The threads of the two threaded rods 26 are opposite, which can drive the two connecting plates 24 to move in opposite directions.

[0019] The reduction gear assembly 6 includes a housing 61, which is fixedly mounted on one side of the support plate 3. A worm gear 62 is rotatably mounted inside the housing 61, and a worm wheel 63 meshes with the outer side of the worm gear 62. A rotating shaft 64 is fixedly passed through the middle of the worm wheel 63. One end of the rotating shaft 64 is rotatably mounted on the inner wall of the housing 61, and the other end of the rotating shaft 64 away from the inner wall of the housing 61 passes through the support plate 3 and is fixedly connected to one end of one of the rotating rods 4. A first motor 65 is fixedly mounted on the outer side of the housing 61. The end of the output shaft of the first motor 65 is fixedly connected to one end of the worm gear 62. The first motor 65 drives the worm gear 62 to rotate, which in turn drives the worm wheel 63 to rotate at a reduced speed. The worm wheel 63 then drives the rotating shaft 64 to rotate at a reduced speed. This avoids the situation where the speed is adjusted too high.

[0020] Working principle: First, the woven bag is passed between two rotating rods 4 and two tension sensors 5. When the tension changes, the strain gauges of the tension sensors 5 deform under force, converting the tension signal into an electrical signal, which is then transmitted to the back-end computer for calculation. The computer then sends a control signal to the first motor 65, causing the first motor 65 to speed up or slow down. The first motor 65 drives the worm gear 62 to rotate, which in turn drives the worm wheel 63 to rotate at a reduced speed. The worm wheel 63 drives the rotating shaft 64 to rotate at a reduced speed, thus avoiding excessive speed. The rotating shaft 64 drives the rotating rods 4 to rotate, and simultaneously, through the gear 8, drives the two connecting shafts 7 to rotate in opposite directions. This causes the connecting shafts 7 to drive the two rotating rods 4 to rotate in opposite directions, thus speeding up or slowing down the conveying of the woven bag by the rotating rods 4. This allows for easy adjustment of the tension of the woven bag behind the rotating rods 4.

[0021] When the rotating rod 4 needs cleaning, the third motor 211 is started first. The end of the output shaft of the third motor 211 drives the adsorption roller 21 to rotate in the opposite direction to the rotating rod 4. Then the second motor 210 is started, so that the second motor 210 starts working. The end of the output shaft of the second motor 210 drives the threaded rod 26 to rotate. Through the connecting rod 28, the two threaded rods 26 rotate synchronously. The threaded rods 26 drive the connecting plate 24 to move in opposite directions. The connecting plate 24 drives the slider 23 to move in the groove 22. The slider 23 drives the adsorption roller 21 to fit against the outside of the rotating rod 4, so that the adsorption roller 21 adsorbs the impurities on the outside of the rotating rod 4. This makes it easy to clean the impurities on the rotating rod 4.
