Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a yarn unwinding stabilizing device for a yarn evenness tester. Background Technology

[0002] The yarn evenness tester is a high-performance, high-efficiency textile testing device. It is used to test the linear density unevenness of yarns, rovings, and slivers, and to analyze the causes of unevenness. It is suitable for testing the evenness of pure and blended yarns made from cotton, wool, linen, and short chemical fibers.

[0003] Chinese Patent Publication No. (CN204112140U) discloses a yarn evenness tester, belonging to the field of textile machinery technology. It includes a yarn guiding mechanism, an evenness testing mechanism, and a yarn take-up mechanism. The left end of the yarn guiding plate of the yarn guiding mechanism is hinged to a yarn guiding bracket and secured by adjusting screws. A yarn guiding hole is provided at the right end of the yarn plate. The evenness testing mechanism includes a yarn feeding roller and a yarn feeding pressure roller, which are adjacent but not in contact. A rack is vertically mounted on a rack support, and the rack meshes with a gear. The left end of a pointer is fixed to the gear, and the right end points to a graduated instrument. A spectrometer roll is coaxially and rotatably mounted on a spectrometer support. A first roller shaft and a second roller shaft are both rotatably mounted on a take-up support, adjacent but not in contact. The yarn take-up mechanism includes a take-up wheel and a take-up pressure roller, which are rotatably mounted at the left end of the take-up bracket and adjacent but not in contact with the take-up wheel. This invention can effectively detect yarn evenness, has a simple structure, and is low in cost.

[0004] However, the above-mentioned utility model still has the following problems: Since the yarn roll itself has a certain height, and the yarn is evenly wound on the outer surface of the yarn roll, the yarn will frequently swing up and down on the surface of the yarn roll when it is unwound. The unwinding mechanism in the above-mentioned utility model is relatively simple and does not have a guiding mechanism for the yarn during the unwinding process. In actual use, when the yarn is unwound at high speed, the up and down swinging of the yarn will cause the yarn to knot or entangle, thus affecting the stability of the yarn unwinding. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a yarn unwinding stabilization device for a yarn evenness tester, which has the effect of strong unwinding stability.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a yarn unwinding stabilizing device for a yarn evenness tester, comprising a base, a yarn evenness tester body fixedly connected to the upper surface of the base, a support platform provided on the top of the base, a controller fixedly connected to the top of the support platform, a high-speed camera electrically connected to the top of the controller, a rotating seat fixedly connected to the top of the support platform, an unwinding roller fixedly connected to the top of the rotating seat, a transmission housing provided on the top of the support platform, a transmission assembly provided inside the transmission housing, a servo motor fixedly connected to one side of the transmission housing, a movable seat provided on the outer surface of the transmission housing, a support rod fixedly connected to the outer surface of the movable seat, and a yarn guide ring fixedly connected to one end of the support rod.

[0007] By adopting the above technical solution, and by setting up a controller, high-speed camera, rotating seat, unwinding roller, transmission housing, transmission components, servo motor, moving seat, support rod, and yarn guide ring, this device allows the high-speed camera to monitor the yarn roll on the unwinding roller throughout the unwinding process and transmit its real-time yarn exit position to the controller. The controller then controls the servo motor, which, through the transmission of the drive gear, driven gear, lead screw, lead screw slide, and limit rod in the transmission components, drives the moving seat to move the yarn guide ring vertically, ensuring that the yarn guide ring is level with the real-time yarn exit height of the yarn roll on the unwinding roller. This design utilizes a high-speed camera to monitor the yarn exit height of the yarn roll on the unwinding roller in real time, and then uses the controller to control the servo motor to adjust the height of the yarn guide ring, ensuring that the yarn guide ring always maintains the same yarn exit height as the yarn roll. This prevents tangling and knotting caused by the yarn swinging up and down during unwinding, thus achieving the high unwinding stability of this device.

[0008] A further feature of this invention is that the transmission assembly includes a drive gear, which is fixedly connected to a servo motor. A driven gear meshes with the bottom of the drive gear. A lead screw is inserted into the inner wall of the driven gear. A lead screw slide is threaded onto the outer wall of the lead screw. A limit rod is fixedly connected to one side of the lead screw slide. The limit rod is fixedly connected to a movable seat.

[0009] By adopting the above technical solution, the drive gear, driven gear, lead screw, lead screw slide and limit rod form a transmission component that can control the moving seat to move up and down. The position of the moving seat can be controlled by the forward and reverse rotation of the servo motor.

[0010] A further feature of this invention is that a strip groove is formed on the outer surface of the transmission housing, and the limiting rod is slidably connected to the strip groove.

[0011] By adopting the above technical solution and setting the strip groove, it is easy to fix the limiting rod and the moving seat.

[0012] A further feature of this invention is that the inner top wall and inner bottom wall of the transmission housing are both fixedly connected to bearing seats, the inner wall of the bearing seats is fixedly connected to bearings, and the lead screw is rotatably connected to the bearing seats through the bearings.

[0013] By adopting the above technical solution and setting a bearing seat, the lead screw is supported and fixed.

[0014] A further feature of this invention is that a strip rail is fixedly connected to the inner wall of the transmission housing, and a sliding block is slidably connected to the outer surface of the strip rail, the sliding block being fixedly connected to the lead screw slide.

[0015] By adopting the above technical solution and setting a strip-shaped sliding block, the stability of the lead screw slide table when sliding on the lead screw is enhanced.

[0016] A further feature of this invention is that: a slide rail is fixedly connected to the upper surface of the base, a slide groove is provided on the lower surface of the support platform, the support platform is slidably connected to the slide rail through the slide groove, and a handle is fixedly connected to one side of the support platform.

[0017] By adopting the above technical solution, and by setting up a slide rail, slide groove, support platform, handle, drive cylinder, pressure plate, and anti-slip pad, the device can be used by pulling the handle to move the support platform laterally on the slide rail. When it moves to the desired position, the drive cylinder works to lower the pressure plate and anti-slip pad until the anti-slip pad contacts the upper surface of the base, thus fixing the position of the support platform. This design achieves the effect of lateral adjustment of the position of the unwinding roller on the support platform. In actual use, the position of the unwinding roller can be flexibly adjusted, thereby enhancing the practicality of the device.

[0018] A further feature of this invention is that there are two slide rails and two slide grooves, and the inner walls of the two slide grooves are fixedly connected to limit sliders, and the number of limit sliders is four.

[0019] By adopting the above technical solution and setting a limit slider, the tightness between the support platform and the slide rail can be improved, thereby improving the stability of the support platform when moving laterally.

[0020] A further feature of this invention is that a cylinder mounting base is fixedly connected to the upper surface of the support platform, and a drive cylinder is fixedly installed on the top of the cylinder mounting base.

[0021] By adopting the above technical solution and setting a cylinder mounting base, the driving cylinder is fixed.

[0022] A further feature of this invention is that a pressure plate is fixedly connected to the output end of the driving cylinder, and an anti-slip pad is fixedly connected to the bottom of the pressure plate.

[0023] By adopting the above technical solution and setting anti-slip pads, the friction between the pressure plate and the base surface is increased, thereby improving the fixing force of the pressure plate on the support platform.

[0024] A further feature of this invention is that a support block is fixedly connected to the lower surface of the base, and the number of the support blocks is eight.

[0025] By adopting the above technical solution and setting up support blocks, the entire device can be supported.

[0026] The beneficial effects of this utility model are as follows: By setting up a controller, a high-speed camera, a rotating seat, an unwinding roller, a transmission housing, a transmission assembly, a servo motor, a moving seat, a support rod, and a yarn guide ring, this device allows the high-speed camera to monitor the yarn roll on the unwinding roller throughout the unwinding process and transmit its real-time yarn exit position to the controller. The controller then controls the servo motor. When the servo motor is working, the transmission assembly, through the drive gear, driven gear, lead screw, lead screw slide, and limit rod, drives the moving seat to move the yarn guide ring vertically, ensuring that the yarn guide ring is level with the real-time yarn exit height of the yarn roll on the unwinding roller. This design utilizes a high-speed camera to monitor the yarn exit height of the yarn roll on the unwinding roller in real time, and then controls the servo motor through the controller to move the yarn guide ring vertically. The height is adjustable to ensure that the guide ring remains at the same height as the yarn exit point of the yarn roll, preventing tangling and knotting caused by the yarn swinging up and down during unwinding, thus achieving the high unwinding stability of the device. By incorporating a slide rail, chute, support platform, handle, drive cylinder, pressure plate, and anti-slip pad, the device allows for lateral movement of the support platform on the slide rail by pulling the handle. Once the desired position is reached, the drive cylinder lowers the pressure plate and anti-slip pad until the anti-slip pad contacts the upper surface of the base, fixing the support platform in place. This design enables lateral adjustment of the unwinding roller position on the support platform, allowing for flexible adjustment of the unwinding roller position during actual use, thereby enhancing the device's practicality.

During operation, the high-speed camera 5 monitors the unwinding process of the yarn roll on the unwinding roller 7, transmitting the real-time yarn exit position to the controller 4. The controller 4 then controls the servo motor 10. When the servo motor 10 operates, it drives the moving base 11 to move the yarn guide ring 13 vertically through the transmission assembly 9, via the drive gear 901, driven gear 902, lead screw 903, lead screw slide 904, and limit rod 905. This ensures that the yarn guide ring 13 is level with the real-time yarn exit height of the yarn roll on the unwinding roller 7. This design utilizes a high-speed camera... The head 5 monitors the yarn exit height on the unwinding roller 7 in real time, and then controls the servo motor 10 through the controller 4 to adjust the height of the yarn guide ring 13 to ensure that the yarn guide ring 13 always maintains the same yarn exit height as the yarn roll, preventing tangling and knotting caused by the up-and-down swing of the yarn during unwinding. This achieves the high unwinding stability of the device. The transmission component 9 includes a drive gear 901, which is fixedly connected to the servo motor 10. A driven gear 902 meshes with the bottom of the drive gear 901. A lead screw 903 is inserted into the inner wall of the driven gear 902. A lead screw slide 904 is threaded onto the outer wall of the lead screw 903. A limit rod 905 is fixedly connected to one side of the lead screw slide 904. The limit rod 905 is connected to the movable seat. The transmission assembly consisting of a drive gear 901, a driven gear 902, a lead screw 903, a lead screw slide 904, and a limit rod 905 forms a fixed connection, enabling the movable seat 11 to move up and down. The position of the movable seat 11 can be controlled by the forward and reverse rotation of the servo motor 10. A strip groove 14 is provided on the outer surface of the transmission housing 8, and the limit rod 905 is slidably connected to the strip groove 14. The strip groove 14 facilitates the fixed connection between the limit rod 905 and the movable seat 11. Bearing seats 15 are fixedly connected to the inner top and bottom walls of the transmission housing 8, and bearings are fixedly connected to the inner walls of the bearing seats 15. The lead screw 903 is rotatably connected to the bearing seats 15 through the bearings. The bearing seats 15 provide support and fixation for the lead screw 903.A strip rail 16 is fixedly connected to the inner wall of the transmission housing 8. A sliding block 17 is slidably connected to the outer surface of the strip rail 16. The sliding block 17 is fixedly connected to the lead screw slide 904. By setting the strip rail 16 with the sliding block 17, the stability of the lead screw slide 904 when sliding on the lead screw 903 is enhanced. A slide rail 18 is fixedly connected to the upper surface of the base 1. A slide groove 19 is opened on the lower surface of the support platform 3. The support platform 3 is slidably connected to the slide rail 18 through the slide groove 19. A handle 20 is fixedly connected to one side of the support platform 3. The device includes a slide rail 18, a slide groove 19, a support platform 3, a handle 20, a drive cylinder 23, a pressure plate 24, and an anti-slip pad 25. In use, pulling the handle 20 moves the support platform 3 laterally along the slide rail 18. Once the desired position is reached, the drive cylinder 23 lowers the pressure plate 24 and anti-slip pad 25 until the anti-slip pad 25 contacts the upper surface of the base 1, thus fixing the position of the support platform 3. This design achieves the effect of lateral adjustment of the position of the unloading roller 7 on the support platform 3. In actual use, the position of the unwinding roller 7 can be adjusted flexibly, thereby enhancing the practicality of the device. There are two slide rails 18 and two slide grooves 19. The inner walls of the two slide grooves 19 are fixedly connected to limit sliders 21. There are four limit sliders 21. By setting the limit sliders 21, the tightness between the support platform 3 and the slide rail 18 can be improved, thereby improving the stability of the support platform 3 when moving laterally. A cylinder fixing seat 22 is fixedly connected to the upper surface of the support platform 3. A drive is fixedly installed on the top of the cylinder fixing seat 22. The cylinder 23 is fixed in place by a cylinder mounting base 22. A pressure plate 24 is fixedly connected to the output end of the cylinder 23, and an anti-slip pad 25 is fixedly connected to the bottom of the pressure plate 24. The anti-slip pad 25 increases the friction between the pressure plate 24 and the surface of the base 1, thereby increasing the fixing force of the pressure plate 24 on the support platform 3. Eight support blocks 26 are fixedly connected to the lower surface of the base 1, providing support for the entire device.

[0035] In this invention, by setting up a controller 4, a high-speed camera 5, a rotating seat 6, an unwinding roller 7, a transmission housing 8, a transmission assembly 9, a servo motor 10, a moving seat 11, a support rod 12, and a yarn guide ring 13, the device allows the high-speed camera 5 to monitor the yarn roll on the unwinding roller 7 throughout the unwinding process and transmit its real-time yarn exit position to the controller 4. The controller 4 then controls the servo motor 10. When the servo motor 10 is working, through the transmission assembly 9 (drive gear 901, driven gear 902, lead screw 903, lead screw slide 904, and limit rod 905), it drives the moving seat 11 to move the yarn guide ring 13 vertically, ensuring that the yarn guide ring 13 is level with the real-time yarn exit height of the yarn roll on the unwinding roller 7. This design utilizes the high-speed camera 5 to monitor the yarn exit height of the yarn roll on the unwinding roller 7 in real time, and then controls the servo motor 10 through the controller 4. The height of the yarn guide ring 13 is adjusted to ensure that it remains consistent with the yarn exit height of the yarn roll, preventing tangling and knotting caused by the yarn swinging up and down during unwinding, thus achieving the high unwinding stability of the device. By setting up a slide rail 18, a slide groove 19, a support platform 3, a handle 20, a drive cylinder 23, a pressure plate 24, and an anti-slip pad 25, the device allows the support platform 3 to move laterally on the slide rail 18 by pulling the handle 20. Once the desired position is reached, the drive cylinder 23 lowers the pressure plate 24 and anti-slip pad 25 until the anti-slip pad 25 contacts the upper surface of the base 1, thus fixing the position of the support platform 3. This design enables lateral adjustment of the position of the unwinding roller 7 on the support platform 3. In actual use, the position of the unwinding roller 7 can be flexibly adjusted, enhancing the practicality of the device.
