Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a high-precision tension control device for roving frames. Background Technology

[0002] In the textile industry, the roving frame is an important piece of equipment for processing cotton slivers or other fiber slivers into roving. During the operation of the roving frame, the tension control of the roving is crucial. Appropriate tension can ensure the quality and production efficiency of the roving, while improper tension can lead to problems such as roving breakage, looseness, and uneven thickness, affecting subsequent spinning processes. Currently, some tension control equipment has a complex structure and is cumbersome to operate, requiring operators to spend a lot of time and energy on adjustment and maintenance. Utility Model Content

[0003] In view of the problems existing in the current high-precision roving frame tension control equipment, this utility model is proposed.

[0004] Therefore, the purpose of this invention is to provide a high-precision tension control device for roving frames, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-precision tension control device for a roving frame includes a base plate and a tensioning wheel. Two grooves are symmetrically arranged on both sides of the upper surface of the base plate, with a slider slidably disposed inside each groove. A vertical rod is rotatably disposed on the upper side of each slider. The tensioning wheel is rotatably sleeved on the upper end of the vertical rod. A rotating rod is rotatably disposed in the middle of the upper surface of the base plate. A rotating strip is fixedly sleeved on the wall of the rotating rod. A strip-shaped opening is formed on the surface of the rotating strip. The upper ends of both vertical rods pass through the strip-shaped opening. A limiting mechanism is provided in the middle of the upper surface of the base plate to restrict the rotation of the rotating rod.

[0007] Preferably, the limiting mechanism includes a first gear and a second gear. The first gear is fixedly sleeved on the lower end of the rotating rod, and the second gear is meshed on one side of the first gear. A square hole is opened in the middle of the second gear, and a square rod is slidably sleeved inside the square hole. The lower end of the square rod is fixedly connected to the base plate.

[0008] Preferably, a stop block is fixedly sleeved on the upper end of the square rod, and a spring is movably sleeved on the rod wall of the square rod. The upper end of the spring is fixedly connected to the stop block, and the lower end of the spring is fixedly connected to the second gear.

[0009] Preferably, the longitudinal section of both the slider and the groove is rectangular, and both sides of the slider abut against the inner wall of the groove.

[0010] Preferably, a sliding rod is horizontally arranged inside the slide groove, and both ends of the sliding rod are fixedly connected to the inner wall of the slide groove. The slider is movably sleeved with the rod wall.

[0011] Preferably, the sidewalls of both tensioning wheels are provided with annular grooves, and the bottom of the annular grooves are both provided with arc-shaped chamfers.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. This utility model, by rotating the rotating rod, drives the rotating bar to rotate. Since the upper ends of the two vertical rods pass through the strip opening of the rotating bar, the rotation of the rotating bar will push the vertical rods to move. The vertical rods drive the slider to slide in the groove, thereby adjusting the distance between the two tensioning wheels, realizing convenient control of the roving tension. Compared with the traditional complex tension control method, this structural design is simpler to operate and greatly saves the time and effort of operators to adjust the tension.

[0014] 2. This utility model, through the setting of the limiting mechanism, can effectively limit the rotation of the rotating rod. After the position of the rotating rod is adjusted, the meshing of the first gear and the second gear, as well as the limiting effect of the square rod on the second gear, can prevent the rotating rod from rotating unnecessarily due to external force or equipment vibration, ensuring the stability of the tension wheel position, thereby ensuring that the roving maintains a suitable and stable tension during the processing, adapting to the strict requirements of high-precision roving machines for tension stability, and meeting different processing conditions.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model discloses a high-precision tension control device for roving frames.

[0023] Reference Figure 1-3 A high-precision tension control device for a roving frame includes a base plate 1 and a tensioning wheel 3. Two grooves are symmetrically formed on both sides of the upper surface of the base plate 1, about the center of the base plate 1. A slider 5 is slidably mounted inside the grooves. Both the slider 5 and the grooves have rectangular longitudinal sections, and both sides of the slider 5 abut against the inner wall of the groove, allowing the slider 5 to slide stably along the groove. A sliding rod 6 is horizontally mounted inside the groove, with both ends of the sliding rod 6 fixedly connected to the inner wall of the groove. The slider 5 is movably sleeved with the rod wall of the sliding rod 6 to minimize the sliding contact. 5. The slider 5 slides out of the groove. A vertical rod 4 is rotatably mounted on the upper side of the slider 5. The tensioning wheel 3 is rotatably sleeved on the upper end of the vertical rod 4. Both side walls of the tensioning wheels 3 are provided with annular grooves. The bottom of the annular grooves is chamfered on both sides to prevent wear on the yarn as much as possible. A rotating rod 2 is rotatably mounted in the middle of the upper surface of the base plate 1. A rotating strip 7 is fixedly sleeved on the rod wall of the rotating rod 2. A strip-shaped opening is provided on the surface of the rotating strip 7. The upper ends of the two vertical rods 4 pass through the strip-shaped opening. A limiting mechanism is provided in the middle of the upper surface of the base plate 1 to limit the rotation of the rotating rod 2.

[0024] Reference Figure 1-3 The limiting mechanism includes a first gear 8 and a second gear 9. The first gear 8 is fixedly sleeved on the lower end of the rotating rod 2, and the second gear 9 is meshed on one side of the first gear 8. A square hole is opened in the middle of the second gear 9, and a square rod 12 is slidably sleeved inside the square hole. The lower end of the square rod 12 is fixedly connected to the base plate 1.

[0025] Reference Figure 1-3 A stop block 10 is fixedly sleeved on the upper end of the square rod 12, and a spring 11 is movably sleeved on the rod wall of the square rod 12. The upper end of the spring 11 is fixedly connected to the stop block 10, and the lower end of the spring 11 is fixedly connected to the second gear 9 to facilitate the reset of the second gear 9.

[0026] In this invention, during use, the tension of the roving needs to be adjusted according to the processing requirements of the high-precision roving frame. The operator rotates the rotating rod 2, which drives the rotating bar 7, which is fixedly sleeved on its wall, to rotate. The strip-shaped opening on the surface of the rotating bar 7 engages with the upper ends of the two vertical rods 4. During the rotation of the rotating bar 7, it pushes the vertical rods 4 to move, and the slider 5 at the lower end of the vertical rods 4 slides in the groove. Since the longitudinal section of the slider 5 and the groove are both rectangular, and the sides of the slider 5 abut against the inner wall of the groove, and the limiting effect of the sliding rod 6 on the slider 5, the slider 5 is ensured to slide stably along the groove. As the slider 5 moves, the vertical rod 4 drives the tension wheel 3 to move, thereby adjusting the distance between the two tension wheels 3 and changing the tension on the roving. When the appropriate tension is adjusted, the first gear 8 and the second gear 9 at the lower end of the rotating rod 2... In the meshing state, the square hole in the middle of the second gear 9 is slidably sleeved with the square rod 12. The square rod 12 is fixed on the base plate 1, which restricts the rotation of the second gear 9, and in turn restricts the rotation of the first gear 8 and the rotating rod 2, thus fixing the position of the tension wheel 3 and maintaining a stable tension of the roving. During the roving process, the roving runs in the annular groove on the side wall of the tension wheel 3. The arc-shaped chamfers on both sides of the bottom of the annular groove can reduce the wear on the roving and ensure the quality of the roving. If it is necessary to readjust the tension, the operator overcomes the elastic force of the spring 11 and lifts the second gear 9 upward, so that the first gear 8 is disengaged from the second gear 9. Then the rotating rod 2 can be rotated again for adjustment. After the adjustment is completed, the second gear 9 is released. Under the action of the spring 11, the second gear 9 resets and re-meets with the first gear 8, thereby limiting the rotation of the rotating rod 2.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
