Description

Technical Field

[0001] This utility model relates to the technical field of papermaking, and in particular to a side support device for a papermaking mesh weaving machine. Background Technology

[0002] In the weaving process of papermaking felt, the two sides of the felt need to be supported to stretch it outwards and ensure the quality of the weaving. Chinese utility model patent CN212357542U discloses a side support device for a papermaking felt loom. This device includes a fixed frame, with a drive motor fixedly connected to the top of the frame. The left end of the drive motor's output shaft is fixedly connected to a rotating shaft via a coupling. This utility model relates to the field of weaving equipment technology. The edge support device of this papermaking blanket loom has a fixed frame installed next to the shuttle of the blanket loom. By loosening the fastening bolts and pulling the sleeve outward, the sleeve slides on the surface of the drive shaft, allowing the support hook of the edge support plate to hook the intersection of the warp and weft threads. This allows for quick adjustment of the position of the edge support plate. When the loom is weaving, the tension of the edge warp and weft threads is transferred to the support hook, which can maintain consistent selvage tension and achieve neat selvage. At the same time, it ensures uniform weft tension during the weaving process, improves the weaving quality of the papermaking blanket, and can be adapted to the use of various blanket looms, thus expanding its application range.

[0003] However, the side support device of the aforementioned papermaking netting loom is relatively troublesome to operate when adjusting the position of the side support plate, and it requires stopping the machine, which delays normal production. Therefore, it needs to be improved. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a side support device for a papermaking mesh weaving machine that can adjust the position of the side support plate and multiple side hooks without stopping the machine, is simple to operate, does not delay normal production, and has good practicality.

[0005] This utility model discloses a side support device for a papermaking mesh weaving machine, comprising a motor frame and a motor. The motor frame is mounted on the machine frame, and the motor is mounted on the motor frame. It also includes a mounting plate, a telescopic shaft, a side support disc, multiple side hooks, a bearing disc, and a telescopic component. The mounting plate is mounted on the motor frame, and the telescopic shaft is rotatably mounted on the mounting plate. The telescopic shaft has a telescopic structure, and its input end is connected to the output shaft of the motor via a coupling. The side support disc is concentrically mounted on the output shaft end of the telescopic shaft. Multiple side hooks are evenly distributed circumferentially on the side support disc. The rotating disc of the bearing disc is concentrically mounted on the end face of the side support disc facing the mounting plate. One end of the telescopic component is connected to the mounting plate, and the other end of the telescopic component is connected to the fixed disc of the bearing disc. The motor frame is mounted on the loom frame. The motor's output shaft drives the telescopic shaft to rotate, which in turn drives the edge support plate and multiple edge hooks to rotate. These edge hooks sequentially hook onto the intersections of the warp and weft threads of the papermaking net, thus tightening the edges of the net. As the edge support plate rotates, the rotating disc of the bearing plate follows it, while the fixed disc of the bearing plate remains stationary with the telescopic components. To adjust the position of the edge support plate and the multiple edge hooks, the length of the telescopic components is adjusted. This allows the telescopic components to push the edge support plate through the bearing plate, which in turn drives the telescopic shaft to extend and retract adaptively. This allows for adjustment of the position of the edge support plate and the multiple edge hooks without stopping the motor. The operation is simple, does not disrupt normal production, and is highly practical.

[0006] Preferably, the telescopic shaft includes a sleeve and an inner shaft. The sleeve is rotatably mounted on a mounting plate, and the inner end of the sleeve is connected to the output shaft of the motor via a coupling. The inner wall of the sleeve is provided with multiple spline grooves. The inner shaft is slidably inserted into the sleeve, and the support plate is concentrically mounted on the outer end of the inner shaft. The outer wall of the inner shaft is provided with multiple splines, and the multiple splines of the inner shaft are slidably connected to the multiple spline grooves of the sleeve. The inner shaft extends and retracts along the sleeve, adjusting the position of the support plate and multiple side hooks. The sleeve and the inner shaft are connected by a spline groove and a spline drive, thereby causing the sleeve to drive the inner shaft, the support plate, and the multiple side hooks to rotate. This technology is mature and has a good driving effect.

[0007] Preferably, it also includes a bearing, which is mounted on a mounting plate, and the sleeve is concentrically mounted in the inner ring of the bearing; by installing the bearing, the sleeve rotates smoothly.

[0008] Preferably, the telescopic component is an electric actuator, a cylinder, or a lead screw assembly.

[0009] Preferably, the assembly also includes multiple rotating shafts (first type), multiple rotating shafts (second type), a dial, an internal gear ring, a push rod, and a spring. Rotating shafts (first type) are installed at the inner ends of multiple hook-shaped parts, and are rotatably connected to the support plate. Rotating shafts (second type) are installed at the middle of multiple hook-shaped parts, and are slidably installed in multiple arc-shaped grooves of the support plate. The dial is concentrically rotatably mounted on the end face of the support plate, and has multiple sliding grooves arranged radially along the dial. The outer ends of multiple rotating shafts (second type) are slidably installed in the sliding grooves of the dial. The internal gear ring is concentrically mounted on the inner wall of the dial. The push rod is slidably mounted on the end face of the support plate. One end of the spring is connected to the push rod, and the other end is mounted on the support plate. The spring force will... The push rod pushes the inner gear ring; when it is necessary to adjust the tilt of multiple edge hooks, thereby adjusting the distance between the outer ends of multiple edge hooks and the center of the support plate, the dial is rotated, causing multiple sliding grooves of the dial to move multiple rotating shafts two, causing multiple rotating shafts two to move along multiple arc grooves of the support plate, causing multiple rotating shafts two to drive multiple edge hooks to rotate around multiple rotating shafts one, thereby adjusting the tilt of multiple edge hooks. When the dial rotates, it drives the inner gear ring to rotate, and the inner tooth peaks of the inner gear ring press the push rod, causing the push rod to compress the spring. When the dial stops, the spring force presses the push rod tightly in the tooth valley of the inner gear ring, elastically positioning the dial, thereby allowing multiple edge hooks to adapt to papermaking wire mesh of different thicknesses, with good versatility.

[0010] Preferably, it also includes an external gear ring, a gear, and a handwheel. The external gear ring is installed on the outer wall of the dial, and the gear is rotatably installed on the end face of the support plate. The gear meshes with the external gear ring, and the handwheel is installed on the gear. When the dial needs to be rotated, the gear is rotated by the handwheel, and the gear meshes and drives the external gear ring to rotate. The external gear ring drives the dial to rotate, thereby adjusting the angle of the dial, simplifying the operation and making it more practical.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The motor frame is installed on the frame of the loom. The output shaft of the motor drives the telescopic shaft to rotate, and the telescopic shaft drives the edge support plate and multiple edge hooks to rotate, so that the multiple edge hooks hook the intersection of the warp and weft threads of the papermaking netting in sequence, thereby tightening the edge of the papermaking netting. When the edge support plate rotates, the rotating disc of the bearing disc follows the edge support plate to rotate, and the fixed disc of the bearing disc and the telescopic component remain stationary. When it is necessary to adjust the position of the edge support plate and multiple edge hooks, the length of the telescopic component is adjusted, so that the telescopic component pushes the edge support plate through the bearing disc, and the edge support plate drives the telescopic shaft to extend and retract adaptively. Thus, the position of the edge support plate and multiple edge hooks can be adjusted without stopping the motor. The operation is simple, does not delay normal production, and has good practicality.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] Example 1

[0020] like Figures 1 to 4As shown, a side support device for a papermaking mesh weaving machine includes a motor frame 1 and a motor 2. The motor frame 1 is mounted on the frame of the weaving machine, and the motor 2 is mounted on the motor frame 1. It also includes a mounting plate 3, a telescopic shaft 4, a side support disc 5, multiple side hooks 6, a bearing disc 7, and a telescopic component 8. The mounting plate 3 is mounted on the motor frame 1, and the telescopic shaft 4 is rotatably mounted on the mounting plate 3. The telescopic shaft 4 is a telescopic structure, and its input end is connected to the output shaft of the motor 2 via a coupling. The side support disc 5 is concentrically mounted on the output shaft end of the telescopic shaft 4. The multiple side hooks 6 are evenly circumferentially mounted on the side support disc 5. The rotating disc of the bearing disc 7 is concentrically mounted on the end face of the side support disc 5 facing the mounting plate 3. The telescopic component 8... One end of the telescopic component 8 is connected to the mounting plate 3, and the other end of the telescopic component 8 is connected to the fixed plate of the bearing disc 7; the telescopic shaft 4 includes a sleeve 9 and an inner shaft 10. The sleeve 9 is rotatably mounted on the mounting plate 3. The inner end of the sleeve 9 is connected to the output shaft of the motor 2 via a coupling. The inner wall of the sleeve 9 is provided with multiple spline grooves. The inner shaft 10 is slidably inserted into the sleeve 9. The support plate 5 is concentrically mounted on the outer end of the inner shaft 10. The outer wall of the inner shaft 10 is provided with multiple splines. The multiple splines of the inner shaft 10 are slidably connected to the multiple spline grooves of the sleeve 9 respectively; it also includes a bearing 11, which is mounted on the mounting plate 3. The sleeve 9 is concentrically mounted in the inner ring of the bearing 11; the telescopic component 8 is an electric actuator, cylinder, or lead screw assembly.

[0021] The motor frame 1 is installed on the frame of the loom. The output shaft of the motor 2 drives the inner shaft 10 to extend and retract along the sleeve 9, adjusting the position of the edge support plate 5 and multiple edge hooks 6. The sleeve 9 and the inner shaft 10 are connected by a spline groove and spline transmission, so that the sleeve 9 drives the inner shaft 10, the edge support plate 5 and multiple edge hooks 6 to rotate. By installing the bearing 11, the sleeve 9 rotates smoothly, so that the multiple edge hooks 6 hook the intersection of the warp and weft threads of the papermaking netting in sequence, thereby tightening the edge of the papermaking netting. When the edge support plate 5 rotates, the rotating disk of the bearing disk 7 follows the rotation of the edge support plate 5. The fixed disk of the bearing disk 7 and the telescopic component 8 remain stationary. When it is necessary to adjust the position of the edge support plate 5 and multiple edge hooks 6, the length of the telescopic component 8 is adjusted, so that the telescopic component 8 pushes the edge support plate 5 through the bearing disk 7. The edge support plate 5 drives the telescopic shaft 4 to extend and retract adaptively, thereby adjusting the position of the edge support plate 5 and multiple edge hooks 6 without stopping the motor 2. The operation is simple, does not delay normal production, and has good practicality.

[0022] Example 2

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, based on Embodiment 1, it further includes multiple rotating shafts 12, multiple rotating shafts 13, a dial 14, an internal gear ring 15, a push rod 16, and a spring 17. Rotating shafts 12 are installed on the inner ends of multiple side hooks 6, and the multiple rotating shafts 12 are rotatably connected to the support plate 5. Rotating shafts 13 are installed in the middle of multiple side hooks 6, and the multiple rotating shafts 13 are slidably installed in multiple arc-shaped grooves of the support plate 5. The dial 14 is concentrically rotatably installed on the end face of the support plate 5, and multiple sliding grooves are provided on the dial 14, arranged radially along the dial 14. The multiple rotating shafts 13... The outer ends are slidably installed in multiple grooves of the dial 14. The inner gear ring 15 is concentrically installed on the inner wall of the dial 14. The push rod 16 is slidably installed on the end face of the support plate 5. One end of the spring 17 is connected to the push rod 16, and the other end of the spring 17 is installed on the support plate 5. The elastic force of the spring 17 pushes the push rod 16 toward the inner gear ring 15. It also includes an outer gear ring 18, a gear 19 and a handwheel 20. The outer gear ring 18 is installed on the outer wall of the dial 14. The gear 19 is rotatably installed on the end face of the support plate 5. The gear 19 meshes with the outer gear ring 18. The handwheel 20 is installed on the gear 19.

[0024] When it is necessary to adjust the tilt of multiple edge hooks 6 to adjust the distance between the outer ends of the multiple edge hooks 6 and the center of the support plate 5, the handwheel 20 is used to rotate the gear 19. The gear 19 meshes and drives the outer gear ring 18 to rotate. The outer gear ring 18 drives the dial 14 to rotate, thereby adjusting the angle of the dial 14. This causes the multiple sliding grooves of the dial 14 to move multiple rotating shafts 13, causing the multiple rotating shafts 13 to move along the multiple arc-shaped grooves of the support plate 5, thus allowing the multiple rotating shafts 13 to move. Multiple edge hooks 6 are driven to rotate around multiple rotating shafts 12, thereby adjusting the tilt state of the multiple edge hooks 6. When the dial 14 rotates, it drives the inner gear ring 15 to rotate. The inner tooth peaks of the inner gear ring 15 press against the push rod 16, causing the push rod 16 to compress the spring 17. When the dial 14 stops, the elastic force of the spring 17 presses the push rod 16 tightly into the tooth valley of the inner gear ring 15, elastically positioning the dial 14. This allows the multiple edge hooks 6 to adapt to papermaking wire mesh of different thicknesses, resulting in good versatility.

[0025] like Figures 1 to 5As shown, this utility model discloses an edge support device for a papermaking netting loom. During operation, the output shaft of the motor 2 drives the sleeve 9 to rotate. The sleeve 9 and the inner shaft 10 are connected via a spline groove and spline transmission. This causes the sleeve 9 to drive the inner shaft 10, the edge support plate 5, and multiple edge hooks 6 to rotate. The multiple edge hooks 6 sequentially hook onto the intersections of the warp and weft threads of the papermaking netting, thus tightening the edge of the papermaking netting. Then, as the edge support plate 5 rotates, the rotating disc of the bearing disc 7 follows the rotation of the edge support plate 5. The fixed disc of the bearing disc 7 remains stationary with the telescopic component 8. When it is necessary to adjust the position of the edge support plate 5 and the multiple edge hooks 6, the length of the telescopic component 8 is adjusted. This allows the telescopic component 8 to push the edge support plate 5 through the bearing disc 7, and the edge support plate 5 drives the inner shaft 10 along... The sleeve 9 adapts to expansion and contraction, thereby adjusting the position of the support plate 5 and multiple edge hooks 6 without stopping the motor 2. Finally, when it is necessary to adjust the tilt of multiple edge hooks 6 to adjust the distance between the outer end of multiple edge hooks 6 and the center of the support plate 5, the handwheel 20 rotates the gear 19. The gear 19 meshes and drives the outer gear ring 18 to rotate. The outer gear ring 18 drives the dial 14 to rotate, thereby adjusting the angle of the dial 14. When the dial 14 rotates, it drives the inner gear ring 15 to rotate. The inner tooth peak of the inner gear ring 15 presses the top rod 16, causing the top rod 16 to compress the spring 17. When the dial 14 stops, the elastic force of the spring 17 presses the top rod 16 tightly in the tooth valley of the inner gear ring 15, elastically positioning the dial 14, so that multiple edge hooks 6 can adapt to papermaking wire mats of different thicknesses.

[0026] The main functions achieved by this utility model are:

[0027] 1. The position of the support plate 5 and multiple edge hooks 6 can be adjusted without stopping the machine. The operation is simple, does not delay normal production, and is highly practical.

[0028] 2. It can flexibly adjust the tilt state of multiple edge hooks 6, thereby adjusting the distance between the outer ends of multiple edge hooks 6 and the center of the support plate 5, adapting to papermaking wire mesh of different thicknesses, and has good versatility.
