Description

Technical Field

[0001] This utility model relates to the field of adhesive bandage production and processing technology, specifically to a rolling cutting device for medical adhesive bandages. Background Technology

[0002] A band-aid is a cleverly designed medical product, usually in the form of a rectangular strip of adhesive tape with a layer of gauze soaked in a special medicine attached to the center. This unique structure gives band-aids multiple functions: they can effectively protect exposed wounds, prevent direct stimulation from the external environment, reduce the risk of wound infection, and act as a physical barrier to prevent the wound from being damaged again during the healing process due to unintentional friction or touch.

[0003] A Chinese patent with publication number CN213440096U discloses a band-aid cutting device. A working backplate is installed at the rear end of the cutting table.

A cutting and forming roller is installed on one side of the auxiliary rotating roller. A conveying roller is installed on the other side of the cutting and forming roller. Band-aid tape is installed inside the conveying roller. A fixed mounting base is installed inside the front end of the working backplate. A second motor is installed inside the front end of the fixed mounting base. The cutting roller is installed at the front end of the second motor.

[0004] However, the above-mentioned roller cutting device has the following disadvantages: the device moves the adhesive bandage roll to be cut by setting a cutting forming roller, an auxiliary rotating roller, a conveying roller and a cutting roller. However, the device can only cut out one size of adhesive bandage. It cannot cut out different sizes of adhesive bandage according to needs, which has low practicality. When cutting other sizes of adhesive bandage, the cutting roller needs to be replaced, which reduces the cutting efficiency. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this invention provides a roller cutting device for medical adhesive bandages, which effectively solves the problem of reduced cutting efficiency caused by the need to replace the cutting roller when cutting adhesive bandages of different sizes.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: Refer to Figures 1 to 4 A medical adhesive bandage cutting device includes a support plate 1. A winding motor 15 is fixedly installed on the side of the support plate 1 away from the cutting barrel 2. Two placement rollers 16 are symmetrically rotatably installed on the side wall of the support plate 1 near the cutting barrel 2. The output end of the winding motor 15 movably passes through the support plate 1 and is fixedly connected to one of the placement rollers 16. The cutting barrel 2 is rotatably installed on one side of the support plate 1. A drive motor 18 is fixedly installed on the side of the support plate 1 away from the cutting barrel 2. The output end of the drive motor 18 movably passes through the support plate 1 and is fixedly connected to a rotating shaft 19. The end of the rotating shaft 19 away from the drive motor 18 is fixedly connected to the cutting barrel 2. A cutting roller 17 is rotatably installed on the side of the support plate 1 away from the winding motor 15, and the cutting roller 17 is used for cutting. Roller 17 is positioned directly below cutting barrel 2. An adjusting column 3 is rotatably mounted inside cutting barrel 2. Multiple adjusting plates 4 are fixedly mounted on the outer side of adjusting column 3. Multiple adjusting grooves 5 arranged in a circular array are formed on the outer wall of adjusting plate 4. Multiple placement grooves 6 arranged in a circular array are formed on the inner wall of cutting barrel 2. A fixing plate 7 is slidably mounted inside the placement groove 6. Multiple sets of cutting blades 8 are fixedly mounted on the side of fixing plate 7 away from adjusting column 3, with adjacent sets of cutting blades 8 having different sizes. Each set of cutting blades 8 has a different number depending on its size. Cutting grooves 9 are formed on the side wall of cutting barrel 2, each corresponding to a different cutting blade 8. This is necessary to cut adhesive bandages into different sizes. When applying the adhesive bandage, one end is fixedly wrapped around the outside of the placement roller 16 (not fixedly installed to the take-up motor 15), and the other end is fixedly installed on the outside of the placement roller 16 (fixedly connected to the take-up motor 15) after passing over the cutting roller 17. During cutting, the drive motor 18 drives the cutting barrel 2 to rotate, and the take-up motor 15 drives the placement roller 16 to rotate, causing the adhesive bandage to move. When the adhesive bandage moves, friction is generated between it and the cutting roller 17, causing the cutting roller 17 to rotate as well. When the cutting barrel 2 rotates, it drives the cutting blade 8 to rotate, cutting the adhesive bandage to the required size on the moving adhesive bandage. When different sizes of adhesive bandage need to be cut, the operator rotates the adjusting column 3 to rotate the adjusting plate 4. When the adjusting plate 4 rotates, it drives the adjusting groove 5 to rotate. When the adjusting groove 5 rotates, it pushes the cutting blade 8 of the required size outward through the cutting groove 9 by squeezing the fixing plate 7. The cutting blades 8 of other sizes are placed inside the support plate 1 through the adjusting groove 5. If there are n different sizes of cutting blades 8 and m groups of each size, then the number of adjusting grooves 5 opened on the outside of the adjusting plate 4 is (n-1)m. The adjusting groove 5 can push out the cutting blades 8 of the adjacent group by rotating 360 / (n·m) degrees each time. The adjustment of the cutting blades 8 by the rotation of the adjusting column 3 and the adjusting plate 4 allows it to cut different sizes of bandages without the need to replace the cutting blades 8. The operation is simple and the cutting efficiency is improved.

[0024] Two sliding columns 10 are symmetrically fixedly installed on the side of the fixed plate 7 away from the adjusting column 3. The end of the sliding column 10 away from the fixed plate 7 moves through the side wall of the cutting barrel 2. A spring 11 is fitted on the outside of the sliding column 10. One end of the spring 11 is fixedly connected to the fixed plate 7, and the other end of the spring 11 is fixedly connected to the inner wall of the mounting groove 6. When the fixed plate 7 and the cutting blade 8 are pushed and squeezed by the adjusting plate 4, the corresponding spring 11 is compressed. When the adjusting plate 4 releases the squeeze, the elastic force of the spring 11 causes it to return to its original position. The sliding column 10 is used to prevent the spring 11 from twisting and tangling.

[0025] The end of the adjusting column 3 away from the support plate 1 moves through the side wall of the cutting barrel 2 and is fixedly installed with a rotating handle 12. A bolt 13 is threaded onto the rotating handle 12. Multiple limiting holes 14 arranged in a ring array are opened on the side wall of the cutting barrel 2 away from the support plate 1. The end of the bolt 13 near the cutting barrel 2 is adapted to the limiting hole 14. By rotating the rotating handle 12, the adjusting column 3 can be rotated. After adjusting the position of the adjusting plate 4, rotating the bolt 13 can rotate it into the corresponding limiting hole 14 to prevent the adjusting column 3 and the adjusting plate 4 from shaking when the cutting blade 8 cuts the adhesive bandage.

[0026] The working principle of this utility model is as follows:

[0027] When it is necessary to cut adhesive bandages into different sizes, one end of the bandage is fixedly wrapped around the outside of the placement roller 16 (not fixedly installed with the take-up motor 15), and the other end is fixedly installed on the outside of the placement roller 16 (fixedly connected to the take-up motor 15) after passing over the cutting roller 17. During cutting, the cutting barrel 2 is rotated by the drive motor 18, and the placement roller 16 is rotated by the take-up motor 15 to move the adhesive bandage. When the adhesive bandage moves, friction is generated between it and the cutting roller 17, causing the cutting roller 17 to rotate as well. When the cutting barrel 2 rotates, it drives the cutting blade 8 to rotate, cutting the required size of adhesive bandage on the moving adhesive bandage. When it is necessary to cut adhesive bandages of different sizes, the operator rotates the adjusting column 3 to drive the adjusting plate 4 to rotate. When the adjustment plate 4 rotates, it drives the adjustment groove 5 to rotate. When the adjustment groove 5 rotates, it pushes the cutting blade 8 of the required size outward through the cutting groove 9 by squeezing the fixing plate 7. Cutting blades 8 of other sizes are placed inside the cutting groove 9 through the adjustment groove 5 under the action of the spring 11. After adjusting the position of the adjustment plate 4, the rotating bolt 13 can rotate it into the corresponding limiting hole 14 to prevent the adjustment column 3 and the adjustment plate 4 from shaking when the cutting blade 8 cuts the adhesive bandage. The adjustment of the cutting blade 8 by the rotation of the adjustment column 3 and the adjustment plate 4 allows it to cut adhesive bandages of different sizes without the need to replace the cutting blade 8. The operation is simple, greatly simplifies the operation process, improves the cutting efficiency, makes the production process smoother, and optimizes the cost-effectiveness.
