Abstract
Description
Technical Field
[0001] This utility model relates to the field of bandage production technology, specifically an automatic roll changing device for bandage production. Background Technology
[0002] In the bandage production process, the continuous supply of bandage rolls is a key link to ensure production continuity, while the bandage roll replacement operation directly affects production efficiency and product quality.
[0003] In existing technologies, the replacement of bandage rolls mostly relies on manual operation or simple auxiliary devices. When the old bandage rolls at the workstation are used up, the operator must first stop the machine, then manually remove the remaining part of the old roll from the equipment, and then move the new bandage roll to the side of the equipment and manually put it onto the subsequent unwinding shaft. After the unwinding is completed, the head of the new roll must be manually pulled into the subsequent conveyor rollers, tension adjusting rollers and other mechanical structures to manually complete the winding and tension adjustment of the bandage. This process is time-consuming, so there is a problem of low bandage production efficiency.
[0004] To address this problem, the present invention provides an automatic roll-changing device for bandage production. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an automatic roll-changing device for bandage production, which solves the aforementioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic roll-changing device for bandage production, comprising a first support, a roll-changing mechanism fixedly connected to the outer surface of the first support, and a connecting mechanism fixedly connected to the side surface of the first support. The roll-changing mechanism includes a support plate fixedly connected to the outer surface of the first support, a first motor fixedly connected to the outer surface of the support plate, a cube fixedly connected to the output shaft of the first motor passing through the outer surface of the support plate, a support shaft fixedly connected to the outer surface of the cube, and the outer surface of the support shaft penetrating the outer surface of the first support. A rotating frame is fixedly connected, and a fixed shaft is fixedly connected to the outer surface of the rotating frame. A bandage roll is sleeved on the outer surface of the fixed shaft. The connecting mechanism includes a second bracket fixedly connected to the side surface of the first bracket. An ultrasonic generator is fixedly connected to the side surface of the second bracket. A fixed plate is fixedly connected to the upper surface of the ultrasonic generator. A second electric telescopic rod is fixedly connected to the upper surface of the fixed plate. A vibrating head is fixedly connected to the output end of the second electric telescopic rod. An anvil is fixedly connected to the outer surface of the second bracket. The anvil is positioned below the vibrating head. An infrared distance sensor is fixedly connected to the side surface of the anvil.
[0007] Furthermore, a bolt is threaded to one end of the fixed shaft away from the rotating frame, and a barrier plate is fitted on the outer surface of the bolt, with the outer surface of the barrier plate fitting against the outer surface of the bandage roll.
[0008] By adopting the above technical solution, the position of the baffle plate can be adjusted by bolts to limit the bandage roll, ensuring accurate axial positioning of the bandage roll on the fixed shaft and preventing the bandage from deviating during roll changing or transportation.
[0009] Furthermore, a first electric telescopic rod is fixedly connected to the lower surface of the support plate, and the output shaft of the first electric telescopic rod passes through the upper surface of the support plate and is fixedly connected to a limiting plate. The upper surface of the limiting plate is in contact with the outer surface of the cube.
[0010] By adopting the above technical solution, the limiting plate is raised by the first electric telescopic rod, which can fit tightly with the cube to achieve rigid limiting and prevent the rotating frame from shifting due to inertia or vibration after the roll is changed.
[0011] Furthermore, a first limiting rod is fixedly connected to the lower surface of the limiting plate, the outer surface of the first limiting rod is slidably connected to the outer surface of the support plate, and a control panel is fixedly connected to the outer surface of the first bracket.
[0012] By adopting the above technical solution, the movement trajectory of the limiting plate can be restricted by the first limiting rod, so as to prevent it from tilting during the lifting and lowering process and ensure the fit between the limiting plate and the cube.
[0013] Furthermore, a second limiting rod is fixedly connected to the upper surface of the vibrating head, and the outer surface of the second limiting rod is slidably connected to the outer surface of the fixing plate.
[0014] By adopting the above technical solution, the movement direction of the vibrating head can be constrained by the second limiting rod, ensuring that it always moves perpendicular to the anvil under the drive of the second electric telescopic rod, thus avoiding misalignment between the vibrating head and the anvil.
[0015] Furthermore, a fixed frame is fixedly connected to the side surface of the second bracket, a second motor is fixedly connected to the outer surface of the fixed frame, a drive gear is fixedly connected to the output shaft of the second motor, a driven gear is meshed with the outer surface of the drive gear, and rubber roller shafts are fixedly connected to the outer surfaces of both the drive gear and the driven gear. The rubber roller shafts are rotatably connected to the inner side of the second bracket, and a bandage body is provided between the rubber roller shafts.
[0016] Using the above technical solution, the rubber roller shaft is driven to rotate synchronously by a second motor through gear transmission. The rubber material can increase the friction with the bandage, ensuring that the bandage does not slip during the conveying process.
[0017] Beneficial effects
[0018] This invention provides an automatic roll-changing device for bandage production. Compared with the prior art, it has the following advantages:
[0019] 1. This automatic roll-changing device for bandage production uses a first motor to drive a cube and a support shaft to rotate a frame, precisely switching the positions of new and old bandage rolls. Combined with the rigid positioning of the first electric telescopic rod and the limiting plate, the rotating frame is firmly fixed, ensuring no deviation after the new roll is moved to the working position. The barrier plate, adjusted by bolts, fits against the side of the bandage roll, achieving axial positioning and preventing conveying deviation. The entire structure works collaboratively, ensuring roll-changing accuracy, reducing production interruptions, effectively connecting subsequent processes, and improving the continuity and stability of bandage production.
[0020] 2. The automatic roll-changing device for bandage production uses an ultrasonic generator to convert electrical energy into high-frequency mechanical vibration through an internal phasor. This vibration head, driven by a second electric telescopic rod, clamps the overlapping area of the new and old bandages together with the cutting board. Through frictional heat generation, a secure connection without consumables is achieved, avoiding the hygiene hazards of adhesives or tapes. This mechanism works in conjunction with the roll-changing mechanism to achieve a fast and reliable connection between the new and old bandages, ensuring continuous production.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0029] Reference Figures 1 to 4This application provides an automatic roll-changing device for bandage production, including a first support 1. A roll-changing mechanism 2 is fixedly connected to the outer surface of the first support 1, and a connecting mechanism 3 is fixedly connected to the side surface of the first support 1. The roll-changing mechanism 2 includes a support plate 209 fixedly connected to the outer surface of the first support 1. A first motor 208 is fixedly connected to the outer surface of the support plate 209. A cube 211 is fixedly connected through the outer surface of the support plate 209. A support shaft 202 is fixedly connected to the outer surface of the cube 211. The outer surface of the support shaft 202 extends through the outer surface of the first support 1, and a rotating frame 201 is fixedly connected to the outer surface of the support shaft 202. A fixed shaft 207 is fixedly connected to the outer surface of the rotating frame 201. The outer surface of the second bracket 207 is fitted with a bandage roll 206. The connecting mechanism 3 includes a second bracket 309 fixedly connected to the side surface of the first bracket 1. An ultrasonic generator 308 is fixedly connected to the side surface of the second bracket 309. A fixing plate 303 is fixedly connected to the upper surface of the ultrasonic generator 308. A second electric telescopic rod 304 is fixedly connected to the upper surface of the fixing plate 303. A vibrating head 306 is fixedly connected to the output end of the second electric telescopic rod 304. An anvil 307 is fixedly connected to the outer surface of the second bracket 309. The anvil 307 is located below the vibrating head 306. An infrared distance sensor 213 is fixedly connected to the side surface of the anvil 307. The infrared distance sensor 213 and the fixed shaft 207 have the same axial height, which facilitates the detection of the amount of bandage roll used.
[0030] Furthermore, a bolt 204 is threadedly connected to one end of the fixed shaft 207 away from the rotating frame 201. A barrier plate 205 is sleeved on the outer surface of the bolt 204. The outer surface of the barrier plate 205 is in contact with the outer surface of the bandage roll 206. A first electric telescopic rod 210 is fixedly connected to the lower surface of the support plate 209. The output shaft of the first electric telescopic rod 210 passes through the upper surface of the support plate 209 and is fixedly connected to a limit plate 212.

The outer surface of the first limit rod 203 is slidably connected to the outer surface of the support plate 209. A control panel 4 is fixedly connected to the outer surface of the first bracket 1.
[0031] In this embodiment, the first motor 208 drives the cube 211, and the support shaft 202 drives the rotating frame 201 to accurately switch the positions of the old and new bandage rolls 206. With the rigid limiting of the first electric telescopic rod 210 and the limiting plate 212, the rotating frame 201 can be firmly fixed to ensure that there is no deviation after the new roll is changed to the working position. At the same time, the baffle plate 205 can be adjusted by the bolt 204 to fit the side of the bandage roll 206 to achieve axial limiting and prevent the conveyor from deviating. The overall structure works in concert to ensure the accuracy of roll changing, reduce production interruption, effectively connect with subsequent processes, and improve the continuity and stability of bandage production.
[0032] Reference Figures 1 to 4 In one aspect of this embodiment, a second limiting rod 305 is fixedly connected to the upper surface of the vibrating head 306, and the outer surface of the second limiting rod 305 is slidably connected to the outer surface of the fixing plate 303.
[0033] Furthermore, a fixed frame 311 is fixedly connected to the side surface of the second support 309, a second motor 310 is fixedly connected to the outer surface of the fixed frame 311, a drive gear 312 is fixedly connected to the output shaft of the second motor 310, a driven gear is meshed with the outer surface of the drive gear 312, and a rubber roller shaft 301 is fixedly connected to the outer surfaces of both the drive gear 312 and the driven gear. The rubber roller shaft 301 is rotatably connected to the inner side of the second support 309, and a bandage body 302 is provided between the rubber roller shafts 301.
[0034] In this embodiment, the ultrasonic generator 308 converts electrical energy into high-frequency mechanical vibration through an internal ionizer. The vibration head 306 is driven by the second electric telescopic rod 304 and together with the anvil 307, it clamps the overlapping area of the new and old bandages. The friction generates heat to achieve a solid connection without consumables, avoiding the hygiene hazards of adhesive or tape. This mechanism works in conjunction with the roll-changing mechanism 2 to achieve a fast and reliable connection between the new and old bandages, ensuring continuous production.
[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0036] Working principle: After the equipment starts, the old bandage roll 206 is stably conveyed in the working position by the clamping of the rubber roller shaft 301. The baffle plate 205 is attached to the side of the bandage roll 206 to ensure its axial positioning does not deviate. When the infrared distance sensor 213 detects that the bandage on the bandage roll 206 is almost used up, it sends a roll change signal through the control panel 4 to start the roll change program. The equipment first stops subsequent production operations to prevent the end position of the old roll from being offset due to the continued pulling of the bandage in subsequent processes. At this time, the first electric telescopic rod 210 retracts, driving the limit plate 212 to descend and release the obstruction. When the cube 211 is positioned, the first motor 208 drives the cube 211, support shaft 202, and rotating frame 201 to rotate, rotating the fixed shaft 207 of the new roll to the working position, while the old roll moves to the standby position. Then, the first electric telescopic rod 210 extends, pushing the limiting plate 212 upward under the guidance of the first limiting rod 203, tightly fitting with the cube 211 to achieve rigid fixation of the rotating frame 201, preventing the new roll from shifting position. Next, the tail of the old roll is conveyed to the upper surface of the anvil 307 and kept taut, while the operator pulls the head of the new roll. The bandage is aligned with the end of the old roll at the same position. Then, the ultrasonic generator 308 is activated, and the second electric telescopic rod 304 pushes the vibrating head 306 vertically downwards under the guidance of the second limit rod 305, transmitting high-frequency vibration to the overlapping area. Frictional heat causes the materials to fuse together. After welding, the vibrating head 306 resets, and the rubber roller 301 continues to transport the joined bandage to subsequent processes. Simultaneously, the operator replaces the old roll with a new one at a spare position. The entire process is cyclical, enabling continuous production. The ultrasonic generator 308 converts electrical energy into high-frequency electrical signals. The signal is transmitted to the transducer built into the vibrating head 306. The transducer converts the high-frequency electrical signal into high-frequency mechanical vibration. When the second electric telescopic rod 304 pushes the vibrating head 306 down, the vibrating head 306 and the cutting board 307 together clamp the overlapping area of the new and old bandages. The high-frequency vibration causes intense friction between the fibers or material molecules in the overlapping area. The heat generated by the friction softens the material locally. Under the pressure of the vibrating head 306, the softened material molecules permeate and fuse with each other. After the vibration stops and the bandages cool down, the new and old bandages form a firm, integrated connection.
