Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, and in particular relates to a warping machine warp breakage automatic stop device. Background Technology

[0002] Warping is a crucial step in the pre-processing of textile manufacturing. Its function is to wind a certain number of yarn cones parallel to the warp beam or weaving beam according to the designed length and arrangement width, preparing them for subsequent sizing and weaving processes. During the warping process, warp breakage is a common defect. If it is not detected and handled in time, it will lead to quality problems such as missing warp threads and warp strands on the warp beam, seriously affecting subsequent production efficiency and fabric quality.

[0003] Existing warp breakage automatic stop devices rely on photoelectric sensors mounted on the transport rollers of the warping machine to detect warp yarn breakage. When a warp yarn breaks, the sensor sends an electrical signal to the machine, causing it to shut down. However, in actual production, the transport rollers continue to rotate due to inertia after power is cut off, resulting in a slower stop and the continued entrapment of broken warp yarns, affecting their evenness. Furthermore, existing warp breakage automatic stop devices cannot monitor warp yarn tension, making it impossible to predict potential risks. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-3 This utility model provides a warping machine warp breakage automatic stop device, including a base 1, and also includes:

[0024] The intermediate plate 6 is vertically fixed to the base 1. Several through holes 7 are arranged side by side on the intermediate plate 6. Rollers 11 are respectively arranged in the several through holes 7. A height detection component is arranged between the rollers 11 and the intermediate plate 6. The height detection component is used to detect the height of the rollers 11 in the through holes 7.

[0025] Two sets of transport rollers 4 are horizontally rotatably connected to the base 1, and the two transport rollers 4 are located on both sides of the middle plate 6. Several textile threads 5 are wound between the two transport rollers 4, and the textile threads 5 pass through several through holes 7. The roller 11 abuts against the top of the textile threads 5. A braking assembly is provided between the transport rollers 4 and the base 1.

[0026] The main function of the through hole 7 is to allow warp yarns to pass through and achieve winding between the two transport rollers 4. The main function of the roller 11 is to reduce friction with the warp yarns. Simultaneously, by pressing down on the warp yarns, when a warp breakage occurs, the roller 11 will automatically fall to the bottom of the through hole 7 because it is no longer supported by the warp yarns. The main function of the height detection component is to detect the height of the roller 11 in the through hole 7. Therefore, when a warp breakage occurs, the falling roller 11 immediately indicates that the corresponding warp yarn has broken. Furthermore, by comparing the heights of the corresponding rollers 11 monitored by several height detection components, the tension of each warp yarn can be determined, facilitating a prediction of warp breakage. The main function of the braking component is to immediately stop the transport rollers 4 when a warp breakage occurs. Overall, this invention can monitor warp breakage in real time, and can also predict warp yarns at risk of breakage by comparing the height differences between the rollers. When a warp breakage occurs, the braking component can immediately stop the transport rollers, achieving a self-stopping effect for warp breakage.

[0027] The solution is further optimized. The height detection component includes a slide 12 opened in the middle plate 6. The bottom of the slide 12 is connected to the through hole 7. A lifting frame 10 slides vertically in the slide 12. A roller 11 is rotatably connected to the bottom of the lifting frame 10. A distance monitoring component is set between the top of the lifting frame 10 and the middle plate 6.

[0028] like Figure 1 As shown, when warp yarns pass through, roller 11 and lifting frame 10 are lifted by the warp yarns. When a warp break occurs, roller 11, without support, will fall down along the slide groove 12 with lifting frame 10. In this embodiment, both lifting frame 10 and roller 11 are made of lightweight materials.

[0029] The solution is further optimized. The distance monitoring component includes a displacement sensor 8 fixedly connected to the top of the intermediate plate 6. The displacement sensor 8 passes through the top of the slide 12 and is set correspondingly to the top of the lifting frame 10. The displacement sensor 8 is used to monitor the distance between the top of the slide 12 and the lifting frame 10.

[0030] Further optimization of the scheme also includes a control module (not shown in the figure), which can receive monitoring signals from several displacement sensors 8 and control the operation of the braking components.

[0031] In this embodiment, the displacement sensor 8 can be a laser rangefinder. For example... Figure 1 and Figure 2 As shown, during normal operation, the roller 11 is supported by the warp yarn, and the lifting frame 10 and the displacement sensor 8 are in a relatively close position. When a yarn breakage causes the lifting frame 10 to fall, and the distance between the lifting frame 10 and the displacement sensor 8 exceeds the threshold, the controller alarms and controls the braking component to operate, so that the transport roller 4 stops rotating.

[0032] During normal production, several displacement sensors 8 can monitor the height change trend of the corresponding lifting frame 10. By comparing the detection values ​​of each displacement sensor 8 through the control module, the position of abnormally high or low height can be compared, thereby achieving the purpose of monitoring warp tension and predicting yarn risks.

[0033] In a further optimized design, a lever 9 is fixedly connected to the side wall of the lifting frame 10. The lever 9 is slidably set inside the intermediate plate 6, and the end of the lever 9 away from the lifting frame 10 extends outward through the intermediate plate 6.

[0034] like Figure 1 As shown, the user can easily lift the roller 11 using the lever 9, which facilitates the passing of the warp yarns before production begins.

[0035] The design is further optimized by fixing several support plates 2 on the base 1, rotating the transport roller 4 between two support plates 2, and setting the braking assembly on one support plate 2.

[0036] The braking assembly is further optimized by including a mechanical box 3 fixedly connected to the side wall of a support plate 2. A brake wheel 13 is provided inside the mechanical box 3. The brake wheel 13 is fixedly connected to one end of the transport roller 4 via a transmission shaft 14. The mechanical box 3 is provided with a braking actuator, which is correspondingly provided with the brake wheel 13.

[0037] In a further optimized design, the braking actuator includes a slide rail 18 fixedly connected to the bottom of the mechanical box 3. A slide plate 17 is slidably connected to the slide rail 18 along the direction of the drive shaft 14. A second brake plate 16 is fixedly connected to one end of the slide plate 17. A first brake plate 15 is slidably connected to the slide plate 17 along the direction of the drive shaft 14. The first brake plate 15 and the second brake plate 16 are located on both sides of the brake wheel 13. A pushing member for pushing the first brake plate 15 to move is provided between the first brake plate 15 and the slide plate 17.

[0038] Further optimization of the scheme: the pushing component includes a motor 19 fixedly connected to the slide plate 17. The motor 19 is located on the side of the first brake plate 15 away from the brake wheel 13. A screw 20 is horizontally fixedly connected to the side of the first brake plate 15 close to the motor 19. A threaded tube 21 is driven connected to the motor 19. The screw 20 is threadedly connected inside the threaded tube 21.

[0039] like Figure 1 and Figure 3 As shown, when the conveyor roller 4 rotates, the brake wheel 13 rotates synchronously. When the roller 11 falls off, the control module controls the motor 19 to rotate. The motor 19 drives the threaded tube 21 to rotate and pushes the screw 20 away from the motor 19 through the threaded transmission, causing the first brake plate 15 to move to the right and fit against the left side of the brake wheel 13. Then, as the first brake plate 15 continues to move, the motor 19 pulls the slide plate 17 to the left under the action of the reaction force, causing the second brake plate 16 to fit against the right side of the brake wheel 13. As the motor 19 continues to rotate, the two brake plates fit tightly against the two sides of the brake wheel 13 respectively, achieving the braking purpose.

[0040] In a further optimized design, one end of the slide rail 18, away from the second brake plate 16, is fixedly connected to one end of the spring 22, and the other end of the spring 22 is fixedly connected to the end of the slide plate 17, away from the second brake plate 16. In its free state, the spring 22 tends to push the slide plate 17 to the right, thus preventing the second brake plate 16 from contacting the brake wheel 13 in the non-braking state.

[0041] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0042] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
