Technical Field
[0001] This utility model relates to the field of medical bandage production technology, specifically a cutting device for medical bandage production. Background Technology
[0002] Medical bandages are gauze strips used to wrap wounds or affected areas. They are common medical supplies and come in many different types and with various bandaging methods. The appropriate type and method must be selected based on the location of the injury. Currently, medical bandages are produced by cutting the gauze into specific lengths using a cutter before being rolled up.
[0003] In the related technology, Chinese patent document with application number CN202221487932.X proposes a medical bandage cutting device. When the length between two sets of cutting blades needs to be adjusted, a fixing rod is pressed down. During this pressing process, a second return spring is compressed, and simultaneously, a locking plate is pressed down from inside the first locking groove into the groove. Then, the fixing rod is rotated. When the connecting block rotates to engage with one of the limiting blocks, the locking plate rotates to the bottom of the second locking groove, releasing the force on the fixing rod. Under the force of the second return spring, the locking plate engages at the top of the second locking groove. At this point, the end of the fixing rod is pulled out from inside the fixing hole. After adjusting the distance, the fixing rod is pressed down again, rotating the locking plate into the first locking groove. At this point, the end of the fixing rod is inserted into the fixing hole, and the fixing block is fixed. When there are too many cutting blades, the fixing block can be slid into the inside of the protective sleeve to protect the cutting blades. When removing the fixing block from inside the protective sleeve, push the protective sleeve backward. The protective sleeve will compress the first return spring, and the fixing block inside the protective sleeve will be exposed.
[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: during the bandage cutting process, the internal mechanical operation of the cutting device will generate vibration, which will cause the material roller to shift, resulting in the bandage deviating during the cutting process, which may affect the cutting accuracy and quality. In view of this, a cutting device for medical bandage production is proposed to solve the above problems. Summary of the Invention

[0027] 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.
[0028] Please see Figure 1-4 and Figure 7This embodiment of a cutting device for producing medical bandages includes a base plate 1, on which a mounting frame 2 and two fixing frames 7 are fixed respectively. A support frame 8 is fixedly connected to one side of the upper end of the base plate 1. A feeding roller 9 is rotatably connected to the upper end of the support frame 8. When in use, the raw material to be cut needs to be placed on the upper end of the feeding roller 9. The feeding roller 9 is rotatably installed inside the mounting frame 2, and a rotating roller 5 is rotatably installed inside the fixing frame 7. An adjustment mechanism 3 is provided on the mounting frame 2, and an installation mechanism 6 is provided on the fixing frame 7.
[0029] The adjustment mechanism 3 includes a fixed box 307. The fixed box 307 is fixed at the upper end of the mounting frame 2. A rotatable adjustment gear 303 is provided inside the fixed box 307. The adjustment gear 303 is located in the middle of the inner side of the fixed box 307. Tooth plates 301 are meshed on both the upper and lower sides of the adjustment gear 303. A connecting plate 304 is fixed on one side of the tooth plate 301. An anti-deviation ring 305 is fixed at the lower end of the connecting plate 304. The anti-deviation ring 305 is slidably connected to the guide roller 4.
[0030] The device starts an external motor, which drives the adjusting gear 303 to rotate. The adjusting gear 303 then meshes with the toothed plates 301 on both sides. The toothed plates 301 drive the anti-deviation rings 305 to move relative to or away from each other, so that the distance between the two anti-deviation rings 305 matches the specifications of the bandage. During use, the two anti-deviation rings 305 can prevent the bandage from shifting during processing, which would affect the cutting accuracy.
[0031] One end of the adjusting gear 303 is driven to rotate by an external motor, which enables the external motor to drive the adjusting gear 303 to rotate. The fixed box 307 is provided with a limiting groove that slides with the toothed plate 301, so that the toothed plate 301 slides more smoothly.
[0032] Meanwhile, a fixed base plate 309 is fixed on one side of each of the two toothed plates 301. A plurality of elastic balls 308 are fixed on one side of the fixed base plate 309, and a buffer plate 306 is fixed on the other side of the elastic balls 308. By setting the elastic balls 308 and the buffer plate 306, the fixed base plate 309 can be shock-absorbing and protected. The toothed plate 301 and the fixed base plate 309 collide for a long time, causing the limit frame to be damaged.
[0033] In addition, the buffer plate 306 and the fixed base plate 309 are slidably connected to the inside of the fixed box 307. The fixed box 307 is provided with multiple sets of rotatable auxiliary gears 302. The multiple sets of auxiliary gears 302 are respectively set on both sides of the adjusting gear 303. By setting the auxiliary gears 302, the auxiliary gears 302 play an auxiliary support role during the movement of the toothed plate 301, making the toothed plate 301 more stable when it moves.
[0034] Please see Figure 5-6 and Figure 8-9In this embodiment, the adjustment mechanism 3 includes a fixed cylinder 603 and a cutting roller 601. The cutting roller 601 is rotatably mounted inside the fixed frame 7. Both the rotating roller 5 and the cutting roller 601 are driven by external drives. Multiple cutting rings 602 are slidably mounted on the cutting roller 601.
[0035] Two fixing cylinders 603 are fixed on one side of the cutting ring 602 and are arranged vertically. A sliding plate 606 is slidably installed inside the fixing cylinder 603. An insert rod 604 is fixed at the lower end of the sliding plate 606. A spring 605 is sleeved on the insert rod 604. The two ends of the spring 605 are fixed to one side of the sliding plate 606 and one side of the inner cavity of the fixing cylinder 603, respectively.
[0036] The cutting roller 601 has grooves 609 on both the upper and lower sides. Multiple slots 608 are provided in the grooves 609 and are evenly distributed. One end of the insertion rod 604 is engaged with the insertion rod 604.
[0037] The device moves the push rod 607 along the L-shaped groove 609 in the limiting shell, from one end to the other. Simultaneously, the spring 605 moves the slide plate 606, causing the slide plate 606 to move the insertion rod 604 outside the slot 608. Then, by pushing the cutting ring 602 to the appropriate position, the push rod 607 is moved along the L-shaped groove 609 in the limiting shell, from one end to the other and locked in place. As the push rod 607 moves, it moves the insertion rod 604 toward one end of the cutting ring 602, and then moves the insertion rod 604 into the groove 609. During this process, the spring 605 is compressed, thus limiting the push rod 607.
[0038] The fixed cylinder 603 has a cavity for the sliding of the push rod 607. The push rod 607 is rotatably connected to the top center of one end of the push column near the fixed cylinder 603. The fixed cylinder 603 is correspondingly provided with a sliding groove for the push rod 607 to move. The sliding groove 609 is an L-shaped sliding groove. The part of the L-shaped sliding groove arranged in the same direction as the axis is for pushing and the other part is for locking. This realizes that by pushing the push rod 607, the sliding plate 606 drives the insertion rod 604 to work, thereby fixing the cutting ring 602.
[0039] The working principle of the above embodiments is as follows:
[0040] In use, the bandage to be cut is first placed on the feeding roller 9. The external motor is started to drive the adjusting gear 303 to rotate. The adjusting gear 303 then meshes with the toothed plates 301 on both sides. The toothed plates 301 drive the anti-deviation rings 305 to move relative to or away from each other, so that the distance between the two anti-deviation rings 305 matches the specifications of the bandage. Then, the bandage is passed through the two guide rollers 4 and placed between the cutting roller 601 and the rotating roller 5. The external device then drives the cutting roller 601 to rotate and cut the bandage.
