Description

Technical Field

[0001] This utility model relates to the technical field of unwinding devices for cotton towel production, specifically an intelligent unwinding control device for cotton towel production. Background Technology

[0002] Cotton wipes are soft, highly absorbent cleaning products made primarily of cotton, widely used in personal care, household cleaning, and infant care. Their core material is typically natural cotton fibers or a blend of cotton and synthetic fibers, woven together using a hydroentangling process to create a non-woven fabric structure, forming a sheet material that combines softness and strength. In the production of cotton towels, an unwinding device is required. This device unwinds the cotton towels rolled on rollers into subsequent equipment for further processing. However, existing unwinding devices typically require replacement just before the unwinding is complete. This involves removing the roller with the unwound cotton towels from the equipment and replacing it with a new roller with unwound cotton towels. In current technology, monitoring the unwinding progress of the unwinding device relies heavily on manual labor or periodic checks based on worker experience. This method is highly dependent on the workers, and if the unwound cotton towels on the rollers are not replaced in time, it will not only affect the normal material supply of subsequent equipment but also cause the unwinding device to run idle, wasting energy.

[0016] 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.

[0017] Please see Figure 1-8 A smart unwinding control device for cotton towel production includes a support base 1. A movable plate 8 is disposed on the other side of the top of the support base 1. Feedback component 1 9 and feedback component 2 10 are fixed to the top of the movable plate 8. Feedback component 1 9 includes a fixed rod 901, a movable seat 902 movably connected to one side of the fixed rod 901, a pressure rod 903 threadedly connected to one side of the movable seat 902, and a feedback box 904 fixed to the bottom of one side of the fixed rod 901. A conductive block 15 is fixed inside the feedback box 904. A [missing information - likely a component name or component] is fixed to the bottom of the movable seat 902. The first contact rod 16 and the top of the movable seat 902 are equipped with an audible and visual alarm 14; the second feedback assembly 10 includes a second fixed rod 1001, a second movable seat 1002 movably connected to one side of the second fixed rod 1001, a second pressure rod 1003 threadedly connected to one side of the second movable seat 1002, and a second feedback box 1004 fixed to the bottom of one side of the second fixed rod 1001. A pressure sensor 21 is installed inside the second feedback box 1004. The first contact rod 16 is fixed to the bottom of the second movable seat 1002. A controller 1005 is also installed on the bottom of the other side of the second fixed rod 1001.

[0018] Please see Figure 1 and Figure 8In this embodiment, the top of the support base 1 is provided with two support plates 2, and a servo motor 3 is installed on one side of the top of one of the support plates 2. The two support plates 2 are rotatably connected to an unwinding assembly 4 driven by the servo motor 3. The unwinding assembly 4 includes an unwinding roller 401 and a cotton towel body 402 wound on the unwinding roller 401.

[0019] Specifically, each of the two support plates 2 has a mating plate rotatably connected to its inner cavity. One of the mating plates is fixed to the power output shaft of the servo motor 3. The two ends of the unwinding roller 401 are respectively inserted into and limited in the two mating plates. When the servo motor 3 is started, it can drive the unwinding roller 401 to rotate and realize the unwinding of the cotton towel body 402. The bottoms of the two support plates 2 are slidably connected to the support base 1 away from each other. The bottoms of the two support plates 2 are threaded with positive and negative screws. Using another motor installed on the side of the support base 1, the positive and negative screws can be driven to rotate, thereby causing the two support plates 2 to move closer or further apart, which facilitates the disassembly and replacement of the unwinding assembly 4.

[0020] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the top of the feedback box 904 has a through hole 9041 that corresponds to and fits the contact rod 16, and the top of the conductive block 15 has a groove to facilitate the bottom of the contact rod 16 to enter. The top of the contact rod 16 is electrically connected to the sound and light alarm 14 through a wire. The contact rod 16 is an iron rod, and its bottom is electrically connected after it is attached to the conductive block 15. The bottom of the conductive block 15 is connected to the mains power through a wire.

[0021] Specifically, when the contact rod 16 descends, it can enter the interior of the feedback box 904 through the through hole 9041, thereby making smooth contact with the conductive block 15, thus connecting the circuit and activating the sound and light alarm 14. The contact rod 16 is an iron rod and can conduct electricity. For safety, an insulating rubber sleeve is fitted on the surface of the contact rod 16.

[0022] Please see Figure 6 and Figure 7 In this embodiment, the top of the feedback box 2 1004 is provided with a perforation 2 10041 that corresponds to and is adapted to the contact rod 22. The pressure sensor 21 is electrically connected to the controller 1005 through a wire, and the controller 1005 is signal connected to the servo motor 3 through a wire.

[0023] Specifically, when the contact rod 22 descends, it can enter the interior of the feedback box 2 1004 through the perforation 2 10041, thereby contacting the pressure sensor 21 inside and providing a pressure signal, so that the servo motor 3 can be turned off by the controller 1005.

[0024] Please see Figure 3 , Figure 4 and Figure 5 In this embodiment, a limiting groove 11 is provided on one side of the fixed rod 901. A limiting rod 1101 is fixed inside the limiting groove 11. A limiting slider 12 fixed on the movable seat 902 is movably sleeved on the limiting rod 1101. A return spring 13 sleeved on the limiting rod 1101 is fixed at the top of the limiting slider 12. The top of the return spring 13 is fixed to the inner top wall of the limiting groove 11.

[0025] Specifically, as the cotton towel body 402 is unwound on the unwinding roller 401, its thickness becomes thinner and thinner. Since the pressure rod 903 presses on the cotton towel body 402, when the thickness of the cotton towel body 402 becomes thinner, it is pushed by the reset action of the reset spring 13 to push the limit slider 12 down, thereby pushing the movable seat 902 to drop in height, which in turn drives the pressure rod 903 and the contact rod 16 to drop in height until the cotton towel body 402 is about to be unwound completely, at which point the contact rod 16 contacts the conductive block 15 to trigger an alarm.

[0026] Please see Figure 6 and Figure 7 In this embodiment, a limiting groove 17 is provided on one side of the fixed rod 1001. A limiting rod 20 is fixed inside the limiting groove 17. A limiting slider 18 fixed on the movable seat 1002 is movably sleeved on the limiting rod 20. A return spring 19 sleeved on the limiting rod 20 is fixed on the top of the limiting slider 18. The top of the return spring 19 is fixed to the inner top wall of the limiting groove 17.

[0027] Specifically, as the cotton towel body 402 is unwound on the unwinding roller 401, its thickness becomes thinner and thinner. Since the pressure rod 1003 presses on the cotton towel body 402, when the thickness of the cotton towel body 402 becomes thinner, it is pushed by the reset spring 19 to push the limit slider 18 down, thereby pushing the movable seat 1002 to descend in height, which in turn drives the pressure rod 1003 and the contact rod 22 to descend in height until the cotton towel body 402 is unwound. Then the contact rod 22 contacts the pressure sensor 21, thereby turning off the control servo motor 3.

[0028] Please see Figure 1In this embodiment, the top of the support base 1 is also provided with a movable groove 6. A servo motor 2 5 is installed on one side of the support base 1 at a position corresponding to the movable groove 6. The power output shaft of the servo motor 2 5 movably passes through the interior of the movable groove 6 and is connected to a lead screw 501. The end of the lead screw 501 away from the servo motor 2 5 is rotatably connected to the inner wall of the other side of the movable groove 6. A movable block 7 is fixed at the center of the bottom of the movable plate 8. The movable block 7 is slidably connected in the movable groove 6 and threaded together with the lead screw 501.

[0029] Specifically, the movable plate 8 can move on top of the support base 1 by being driven by the second servo motor 5, thereby moving the first feedback component 9 and the second feedback component 10 away from the unwinding component 4, making it easier to replace the unwinding component 4 and avoiding obstruction. After the second servo motor 5 is started, it can drive the lead screw 501 to rotate, thereby causing the movable block 7 threaded with it to slide in the movable groove 6, thereby moving the movable plate 8.

[0030] Please see Figure 2 and Figure 6 In this embodiment, both pressure rod 903 and pressure rod 1003 are cylindrical rods, and the surfaces of both pressure rod 903 and pressure rod 1003 are designed to be smooth.

[0031] Specifically, the cylindrical pressure bar 903 and the pressure bar 1003 with smooth surfaces can contact the cotton soft towel body 402 to avoid affecting the unrolling of the cotton soft towel body 402.

[0032] When using: The cotton towel body 402 that needs to be unrolled is placed between two support plates 2 via the unrolling roller 401; Start the servo motor 2 5. The power output shaft of the servo motor 2 5 drives the lead screw 501 to rotate, thereby causing the movable plate 8 to move towards the side of the unwinding assembly 4 on the top of the support base 1. Then, pull the movable seat 1 902 upward, thereby causing the return spring 13 to compress and thread the pressure rod 1 903 to the side of the movable seat 1 902. After releasing the movable seat 1 902, the pressure rod 1 903 presses on the cotton soft towel body 402 of the unwinding roller 401. Similarly, the pressure rod 2 1003 can be threaded onto the movable seat 2 1002 and press on the cotton soft towel body 402 of the unwinding roller 401. After servo motor 3 starts, it enables the unwinding of the cotton towel body 402 from the unwinding roller 401. As the unwinding time increases, the thickness of the cotton towel body 402 on the unwinding roller 401 gradually decreases. The movable seat 902 gradually descends under the reset effect of the return spring 13, thereby driving the pressure rod 903 and the contact rod 16 to descend. Similarly, the movable seat 1002 gradually descends under the reset effect of the return spring 19, thereby driving the pressure rod 1003 and the contact rod 22 to descend. When the thickness of the cotton towel body 402 reaches the point where the unwinding is about to end, the contact rod 16 enters the feedback box 904 and contacts the conductive block 15, thereby enabling the energization of the audible and visual alarm 14 (e.g., Figure 4 As shown), the sound and light alarm 14 is used to remind nearby staff to replace the unwinding assembly 4. When there are no staff nearby or no time to replace the towel, the cotton towel body 402 continues to unroll. When the cotton towel body 402 is completely unrolled from the unwinding roller 401, the pressure rod 1003 contacts the unwinding roller 401, and the contact rod 22 enters the feedback box 1004, thereby contacting the pressure sensor 21 (e.g., Figure 7 As shown, when the pressure sensor 21 receives a pressure signal, it can use the controller 1005 to shut down the servo motor 3 through signal transmission with the controller 1005, thereby avoiding the continuous idling of the servo motor 3. This realizes the monitoring of the unwinding device on the unwinding of the cotton towel body 402, which not only serves to remind the staff, but also realizes the effect of intelligent control to stop the servo motor 3.

[0033] It should be noted that the controller 1005, the audible and visual alarm 14 and the pressure sensor 21 are all common knowledge in the field, and their working principles are known technologies. The specific model and specifications can be selected and determined according to the device and the actual situation, so they will not be described in detail.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
