Description

Technical Field

[0001] This utility model relates to the field of medical casting film processing technology, and in particular to an adjustable cutting device for medical casting film processing. Background Technology

[0002] Medical cast film is a thin film material prepared by casting process. In the medical field, it is often used for surgical wrapping, medical dressings, etc. During the processing of medical cast film, it is necessary to cut the medical cast film, so an adjustable cutting device for medical cast film processing is used.

[0003] To address this, patent CN217915651U discloses an adjustable cutting device for cast film processing, comprising a support leg, a main body, a film feeding roller, a driven roller, and a moving roller. The main body is mounted on the upper end of the support leg, and the film feeding roller and driven roller are installed inside the main body. The moving roller is also installed inside the main body, and a conveyor belt is fitted around its outer side. Support blocks are mounted on the outer sides of both ends of the main body, and hydraulic push rods are mounted on the upper ends of the support blocks. Two sets of rotating rods are installed through the interior of the connecting plate, and limit rods are installed inside the rotating rods. In this adjustable cutting device for cast film processing, the operator can rotate the left rotating rod to move the rotating block vertically. During this movement, the mounting plate rotates around the lower end of the mounting block, causing the cutting blade to rotate synchronously. This completes the angle adjustment process of the cutting blade, thereby effectively improving the cutting effect of the device.

[0004] Although the adjustable cutting device for casting film processing described above completes the angle adjustment process of the cutting blade, thereby effectively improving the cutting effect of the device, its applicability is low because it is inconvenient to fix and it is difficult to ensure that the cutting edge of the casting film is neat. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable cutting device for medical casting film processing, in order to solve the defect of existing adjustable cutting devices for medical casting film processing being inconvenient to fix.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable cutting device for medical casting film processing, including a worktable and a film roller;

[0007] A film feeding frame is provided on one side of the workbench, a film roller is provided on the top of the film feeding frame, and a feeding structure is fixed on one side of the top of the workbench.

[0008] The top of the workbench on one side of the feeding structure is fixed with a fixing structure, which includes a fixing frame fixed to the top of the workbench. A first electric push rod passes through one side of the top of the fixing frame, and a second electric push rod passes through the other side of the top of the fixing frame. A fixing plate is fixed to the bottom of the second electric push rod, and a sliding rod passes through the interior of the fixing frame on both sides of the second electric push rod.

[0009] The bottom of the workbench is provided with a positioning structure.

[0010] When using this device, the fixed structure facilitates neat cutting, thereby improving the applicability of the adjustable cutting device for medical cast film processing; the feeding structure facilitates film feeding, ensuring the continuity of medical cast film delivery; and the positioning structure facilitates limiting the cutting length, further enhancing the ease of use of the adjustable cutting device for medical cast film processing.

[0011] Preferably, a cutter is fixed to the bottom end of the first electric push rod, and slide blocks are fixed to both sides of the cutter. A sliding groove is formed inside the fixing frame on one side of each slide block, a blade groove is formed at the bottom of the fixing frame below the cutter, and pre-reserved grooves are evenly formed inside the fixing frame at the top of the blade groove. Under the action of the slide rod, the stability of the fixing plate during movement is enhanced. After movement, the fixing plate causes the anti-slip pad to press against the top of the cast film. The anti-slip pad increases the friction between the cast film and the fixing plate, thus facilitating the fixing of the cast film.

[0012] Preferably, the slide block and the fixing frame form a sliding structure through a sliding groove, and the slide rod and the fixing frame form a sliding structure. The bottom end of the slide rod is fixedly connected to the top end of the fixing plate, and an anti-slip pad is fixed to the bottom end of the fixing plate. At this time, the cutter starts to work. Under the action of the slide block and the sliding groove, the stability of the cutter during movement is enhanced. After moving, the cutter cooperates with the cutter groove to complete the cutting of the cast film. Under the action of the fixing plate, the cutting edge is kept neat.

[0013] Preferably, the feeding structure includes a support, movable rods, a return spring, a movable frame, a first conveying roller, a drive motor, and a second conveying roller. The support is fixed to the top of the worktable, and the second conveying roller is located at the bottom of the support. A drive motor is installed on the outer wall of the support at one end of the second conveying roller. Movable rods are evenly distributed through the top of the support, and movable frames are fixed to the bottom ends of the movable rods. Return springs are sleeved on the outer sides of the movable rods, and the first conveying roller is rotatably connected to the bottom of the movable frame. When the second conveying roller rotates, it drives the cast film to move, and the cast film drives the first conveying roller to rotate. Under the elastic force of the return spring, the top end of the first conveying roller is always in contact with the top end of the cast film.

[0014] Preferably, the movable rod and the bracket form a sliding structure, with a baffle fixed to the top of the movable rod, and one end of the second conveying roller extending to the outside of the bracket and fixedly connected to the output end of the drive motor. Simultaneously, the distance between the first and second conveying rollers can be adjusted according to the thickness of the cast film, ensuring that the cast film is smoothly and stably pulled from the film rollers to the worktable, providing continuous and stable feeding for subsequent positioning and cutting.

[0015] Preferably, the positioning structure includes a support frame, a movable plate, a movable slot, a movable seat, a connecting seat, a servo motor, a threaded rod, a movable frame, a third electric push rod, a fixed rod, a pressure plate, and a support rod. The support frame is fixed to the bottom of the worktable. Movable slots are passed through both sides of the interior of the worktable. Connecting seats are passed through the interior of each movable slot. A threaded rod is provided on one side of the interior of the support frame. A movable seat is threaded to the outer side of the threaded rod. A support rod is passed through one side of the interior of the movable seat. A servo motor is installed on the outer wall of the support frame at one end of the threaded rod. A movable plate is fixed to the top of the connecting seat. Movable frames are uniformly fixed on one side of the movable plate. A third electric push rod is passed through the top of each movable frame. A pressure plate is fixed to the bottom of each third electric push rod. Fixed rods are passed through both ends of one side of the pressure plate.

[0016] Preferably, the connecting seat and the worktable form a sliding structure through a movable groove. The bottom end of the connecting seat is fixedly connected to the top end of the movable seat. The movable frame and the fixed frame form a sliding structure through a reserved groove. One end of the threaded rod extends to the outside of the support frame and is fixedly connected to the output end of the servo motor. When the movable frame moves into the interior of the reserved groove, the stability of the pressure plate during movement is enhanced by the action of the fixed rod. The moved pressure plate causes the rubber pad to press against the top of the cast film. Under the action of the rubber pad, the friction between the movable frame, the pressure plate, and the cast film is increased, thereby facilitating the fixing of the cast film.

[0017] Preferably, the movable seat and the support rod form a sliding structure, with both ends of the support rod fixedly connected to the inner wall of the support frame. The fixed rod and the pressure plate form a sliding structure, with both ends of the fixed rod fixedly connected to the inner wall of the movable frame. Rubber pads are fixed to the bottom of the movable frame and the bottom of the pressure plate. At this time, the fixed plate causes the anti-slip pad to separate from the cast film, and the threaded rod starts to work. Under the action of the support rod, the movable seat is prevented from rotating with the threaded rod. The movable seat will drive the movable plate to move through the connecting seat, and the movable plate will drive the cast film to move through the movable frame, thereby achieving precise positioning of the cast film and ensuring the consistency of the cutting length. At the same time, the moving position of the movable seat can be adjusted by the threaded rod to adapt to the needs of different cutting lengths.

[0018] The adjustable cutting device for medical casting film processing provided by this utility model has the following advantages:

[0019] By incorporating a fixed structure, the stability of the fixed plate during movement is enhanced by the sliding rod. After movement, the fixed plate causes the anti-slip pad to press against the top of the cast film. The anti-slip pad increases the friction between the cast film and the fixed plate, thus facilitating the fixation of the cast film. At this point, the cutter begins to work. The stability of the cutter during movement is enhanced by the sliding block and the sliding groove. After movement, the cutter cooperates with the cutting groove to cut the cast film. The fixed plate ensures that the cut edges are neat, thus realizing the function of easy and neat cutting and improving the applicability of this adjustable cutting device for medical cast film processing.

[0020] With a feeding structure, when the second conveyor roller rotates, it drives the cast film to move. At the same time, the cast film drives the first conveyor roller to rotate. Under the elastic force of the return spring, the top of the first conveyor roller is always in contact with the top of the cast film. The distance between the first and second conveyor rollers can be adjusted according to the thickness of the cast film to ensure that the cast film is pulled flat and stably from the film roller to the worktable. This provides a continuous and stable supply for subsequent positioning and cutting, realizing the function of easy film feeding of the device and thus ensuring the continuity of medical cast film feeding.

[0021] With its positioning structure, when the moving frame moves into the pre-reserved slot, the stability of the pressure plate during movement is enhanced by the fixing rod. The moved pressure plate then presses the rubber pad against the top of the cast film. The rubber pad increases the friction between the moving frame, the pressure plate, and the cast film, facilitating the fixing of the cast film. At this point, the fixing plate separates the anti-slip pad from the cast film, and the threaded rod begins to work. Under the action of the support rod, the moving seat is prevented from rotating with the threaded rod. The moving seat moves the movable plate through the connecting seat, and the movable plate moves the cast film through the moving frame, thus achieving precise positioning of the cast film and ensuring consistent cutting length. Simultaneously, the moving position of the moving seat can be adjusted via the threaded rod to accommodate different cutting length requirements, enabling the device to easily limit the cutting length and improving the ease of use of this adjustable cutting device for medical cast film processing.
