A cutting device is installed between the housing and the base, and the cutting device includes a ring-shaped cutting blade. A horizontally distributed worktable is installed on the top surface of the base, and a horizontally movable pressing and blocking device is slidably connected to the worktable. A horizontally distributed first displacement device is installed on the frame, and a horizontally distributed second displacement device is slidably connected to the first displacement device. The movement direction of the second displacement device is parallel to the movement direction of the pressing and blocking device, and a feeding table is slidably connected to the second displacement device. The feeding table moves in a direction perpendicular to the pressing and blocking device. A pressing device is installed at the end of the feeding table near the worktable, opposite to the pressing and blocking device. The blade of the cutting blade is located between the pressing and blocking device and passes through the worktable. This utility model uses a wire saw to cut the bandage roll. However, although the wire saw can cut the bandage roll, it occupies a large space and needs to be set up as a long strip from top to bottom. Moreover, the cut surface of the bandage roll is relatively rough and has many burrs. This not only reduces the cutting yield of the bandage roll, but also causes some discomfort to the patient when using it for bandaging.
[0004] Based on the above background, a bandage roll slitting machine is proposed to solve the problem. Utility Model Content

Detailed Implementation
[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 embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0023] Please see Figure 1-3 This utility model provides a bandage roll slitting machine, including: a machine housing 1, a conveyor 2 installed on the machine housing 1 for conveying bandage rolls, two pressing devices 3 located on the right side of the conveyor 2, and a cutting saw blade 4 inserted on the machine housing 1. There is a gap between the two pressing devices 3 through which the cutting saw blade 4 passes. A discharge platform 5 is provided on the conveyor 2 and located on the right side of the conveyor 2. A drive assembly 6 and a linear module assembly 7 are installed inside the machine housing 1. The drive assembly 6 is connected to the cutting saw blade 4 and is installed on the linear module assembly 7.
[0024] In operation, the cutting saw blade 4 is inserted into the housing 1 and positioned between the two pressing devices 3. The long bundle of bandage is conveyed forward by the conveyor 2, passing through the two pressing devices 3. The pressing devices 3 move down to press down on the bandage and stop conveying. The drive assembly 6 then controls the cutting saw blade 4 to rotate at high speed. The linear module assembly 7 controls the drive assembly 6 to move with the saw blade 4. During the movement, the pressed bandage is cut into segments. Then, the pressing devices 3 release the pressure on the bandage, and the conveyor 2 continues to convey the bandage forward, so that the cut bandage is pushed onto the discharge table 5 until it is discharged.
[0025] According to some embodiments of this application, optionally, the discharge table 5 is installed below the rightmost of the two pressing devices 3. It has the function of pressing the bandage roll to be cut onto the discharge table 5, so that the cut bandage roll can be fed out from the discharge table 5.
[0026] According to some embodiments of this application, optionally, the pressing device 3 includes a pressing cylinder and a pressing plate. The pressing cylinder is mounted on the housing 1, and the pressing plate is connected to the pressing cylinder. The discharge platform 5 is located below the pressing plate, and the cutting saw blade 4 is located between the two pressing cylinders. By controlling the movement of the pressing plate through the pressing cylinder, the pressing plate is pressed down to prevent the bandage roll from shifting, making the bandage roll more stable and the cut surface smoother when the cutting saw blade 4 cuts through it.
[0027] According to some embodiments of this application, optionally, the cutting saw blade 4 is a metal cutting saw blade. Metal cutting saw blades have the advantages of high hardness and strong wear resistance. They distribute force more evenly during cutting, can separate materials more accurately, reduce the squeezing and tearing of the workpiece, avoid burrs caused by local stress concentration when cutting the bandage roll, and make the cut surface of the bandage roll smoother, thus improving the cutting quality.
[0028] According to some embodiments of this application, optionally, the drive assembly 6 includes a support frame 61 located inside the housing 1, a first motor 62 mounted on the support frame 61, a bearing seat 63 disposed on the support frame 61, and a rotating rod 64 inserted through the bearing seat 63. The first motor 62 is connected to the rotating rod 64 via a belt, and the cutting saw blade 4 is connected to the side of the rotating rod 64. By controlling the rotation of the first motor 62, the rotating rod 64 will smoothly rotate with the cutting saw blade 4 under the action of the bearing seat 63, enabling it to smoothly cut the bandage roll.
[0029] According to some embodiments of this application, optionally, the support frame 61 is mounted on the linear module assembly 7. This serves to mount the drive assembly 6 on the linear module assembly 7.
[0030] According to some embodiments of this application, optionally, the linear module assembly 7 includes a second motor 71 located inside the housing 1, a screw 72 connected to the drive rod of the second motor 71, a base plate 73, a slide rail 74, a slider 75, and a limiting seat 76. The limiting seat 76 is mounted on the base plate 73. The screw 72 is rotatably mounted on the limiting seat 76. A threaded block is provided at the bottom of the support frame 61 and is threadedly connected to the screw 72. The two sides of the bottom of the support frame 61 are connected to the slider 75. The slider 75 is clearance-fitted with the slide rail 74, and the slide rail 74 is mounted on the base plate 73. The second motor 71 controls the screw 72 to rotate in place on the limiting seat 76. When rotating, the support frame 61 is limited by the slider 75 and the slide rail 74, so the support frame 61 does not rotate with it. Instead, the screw 72 and the threaded block drive the support frame 61 to translate, thereby moving the drive assembly 6, and then moving the cutting saw blade 4 to contact the bandage roll for a stable cutting process.
[0031] According to some embodiments of this application, optionally, a shim plate 8 is bolted to the discharge platform 5. The height of the shim plate 8 on the discharge platform 5 is flush with the feeding height of the conveyor 2. Since there is a certain height difference between the discharge platform 5 and the conveyor 2, this height difference will cause the bandage roll to be pressed down by the pressing device 3 when it is conveyed to the discharge platform 5, pressing it onto the lower discharge platform 5, causing the bandage roll to bend or curl up. This will be extremely detrimental to the cutting process, and the cut surface will be crooked and uneven.
[0032] According to some embodiments of this application, optionally, a baffle cylinder 9 is installed on the right-side pressing device 3, and a baffle plate 10 is connected below the baffle cylinder 9. When multiple bundles of bandages are placed on the conveyor 2, the movable end of the baffle cylinder 9 can be extended so that the baffle plate 10 falls on the discharge table 5. In this way, when the ends of the multiple bundles of bandages are aligned manually, the baffle plate 10 can prevent misalignment between the ends of the multiple bundles of bandages. Therefore, when cutting each group of bandages, no defective products will be produced in the first and last cuts, thereby improving the yield of bandages and reducing production costs. In addition, the baffle cylinder 9 only operates before the first cut of each group of bandages and does not operate during subsequent cuts of that group of bandages until the first cut of the next group of bandages.
