Description

Technical Field

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

[0002] Medical dry film processing is a key technological step in the production of medical imaging materials. It primarily involves coating, drying, slitting, and cutting rolls of substrate to create finished films that meet clinical diagnostic standards. These films are widely used for the output and archiving of medical images such as X-rays, CT scans, and MRIs. As a crucial component of the medical imaging industry chain, its processing quality, stability, and degree of automation have a decisive impact on the clarity, ease of use, and production efficiency of the final images. Particularly in the core process of film cutting, existing cutting equipment has gradually revealed a series of significant limitations and technical problems when handling rolls of medical dry film.

[0003] Existing medical dry film cutting devices generally lack effective roll stretching during actual operation. Because medical dry films are thin, smooth, and have a certain degree of flexibility, manual unwinding is extremely inconvenient, severely impacting subsequent positioning and cutting accuracy. Therefore, to address the numerous shortcomings of existing technologies, we urgently need an innovative cutting device to solve the technical challenge of effectively stretching medical dry film rolls during processing. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for processing medical dry film, which solves the problem that the existing technology generally lacks effective roll stretching. Because medical dry film is thin, has a smooth surface and a certain degree of flexibility, it is extremely inconvenient to unwind manually, which seriously affects the subsequent positioning and cutting accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cutting device for processing medical dry film includes a frame, a support frame slidably connected to one inner side of the frame, a winding rod rotatably connected to one inner side of the frame, and film wound on the winding rod. A top frame is fixedly connected to one top side of the frame, and a second cylinder is fixedly connected to one top side of the top frame by bolts. A support plate is provided on the inner side of the top frame, and the output shaft of the second cylinder passes through the top of the top frame and is fixedly connected to the top of the support plate. A cutter is fixedly connected to the bottom of the support plate. A hydraulic cylinder is fixedly connected to one outer wall of the frame by bolts, and the output shaft of the hydraulic cylinder passes through the side wall of the frame and is fixedly connected to one side of the support frame. A clamping plate is elastically connected to the inner side of the support frame.

[0006] Preferably, a first cylinder is fixedly connected to the top side of the support frame by bolts, and the output shaft of the first cylinder passes through the top of the support frame and is fixedly connected to the top of the clamping plate.

[0007] Preferably, compression springs are fixedly connected to both sides of the top of the clamping plate, and the top ends of the two compression springs are fixedly connected to the top inner side of the bearing frame.

[0008] Preferably, a support plate is fixedly connected to the bottom inner side of the frame, and a cutting groove is provided on the top of the support plate, which is located at the bottom of the cutter.

[0009] Preferably, one end of the winding rod is rotatably connected to the inner wall of the frame via a pivot, a guide frame is fixedly connected to one side of the inner side of the frame, and one end of the film passes through the guide frame.

[0010] Preferably, a slider is fixedly connected to one side of the support frame, and the slider is slidably connected to the side wall of the frame through a groove. Two telescopic rods are fixedly connected to one side of the support frame, and one end of each telescopic rod is fixedly connected to the inner wall of the frame.

[0011] This utility model has the following beneficial effects: By incorporating a sliding support frame and elastic clamping plates, reliable fixing and active stretching of the rolled film ends are achieved, effectively solving the technical defects of inconvenient manual unwinding and easy wrinkling or stacking of the film. The horizontal movement of the support frame driven by a hydraulic cylinder applies stable and controllable tension to the film, ensuring it is fully stretched and flat before cutting. This significantly improves the flatness and stability of the film in the cutting area, preventing uneven cuts, edge burrs, or tearing caused by film looseness, thus improving cutting accuracy and product qualification rate. The clamping plates use an elastic connection method, providing buffer pressure during clamping to adapt to the clamping needs of films of different thicknesses, preventing damage to the surface coating or insecure clamping, and enhancing the adaptability and safety of the equipment. The sliding movement of the support frame within the frame, combined with the free rotation of the winding rod, forms a stable unwinding and traction system, ensuring uniform force and smooth operation of the film during stretching. It reduces vibration and offset; the cutter is driven vertically downward by a second cylinder, with rapid and accurate positioning. This, combined with the stretching action of the support frame, ensures the film is completely fixed and flattened at the moment of cutting, further improving cutting quality. The overall structure is rationally laid out, with all components such as the frame, support frame, winding rod, clamping plate, hydraulic cylinder, top frame, second cylinder, support plate, and cutter working together. This not only achieves automatic stretching and precise cutting of the film roll, but also significantly reduces manual intervention and operational complexity, shortens cutting preparation time, and improves production cycle and processing efficiency. This device is particularly suitable for the high-efficiency processing needs of hospital radiology departments, third-party testing institutions, and film manufacturers for large-volume, multi-specification medical dry films. It effectively solves the prominent problems of low cutting efficiency, high scrap rate, and inconvenient operation caused by insufficient stretching and poor tension control in traditional equipment, demonstrating good practical value and promising prospects for promotion.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Reference Figure 1-5 A cutting device for processing medical dry film includes a frame 1, a support frame 2 slidably connected to one side of the inner side of the frame 1, and a winding rod 11 rotatably connected to one side of the inner side of the frame 1, with film 12 wound on the winding rod 11. A top frame 14 is fixedly connected to one side of the top of the frame 1, and a second cylinder 17 is fixedly connected to one side of the top of the top frame 14 by bolts. A support plate 15 is provided on the inner side of the top frame 14, and the output shaft of the second cylinder 17 passes through the top of the top frame 14 and is fixedly connected to the top of the support plate 15. A cutter 16 is fixedly connected to the bottom of the support plate 15. A hydraulic cylinder 18 is fixedly connected to one side of the outer wall of the frame 1 by bolts, and the output shaft of the hydraulic cylinder 18 passes through the side wall of the frame 1 and is fixedly connected to one side of the support frame 2. A clamping plate 6 is elastically connected to the inner side of the support frame 2.

[0017] First, the rolled film 12 is mounted on the winding rod 11 on one side of the inner side of the frame 1, ensuring that the roll can be freely rotated and unwound. Then, the free end of the film 12 is led out horizontally, passes through the guide path inside the frame 1, and extends into the inner cavity of the support frame 2. The support frame 2 is provided with a clamping plate 6, which is elastically connected to the inner wall of the support frame 2 through an elastic element. After the end of the film 12 enters, the clamping plate 6 automatically presses the edge of the film 12 under the action of elastic restoring force, realizing a stable clamping of the end of the film 12. After clamping is completed, the hydraulic cylinder 18 fixed on one side of the outer wall of the frame 1 is activated. Its output shaft passes through the side wall of the frame 1 and is fixedly connected to one side of the support frame 2. The piston rod of the hydraulic cylinder 18 extends outward, pushing the support frame 2 to move horizontally away from the winding rod 11 along the sliding structure inside the frame 1. During the movement of the support frame 2, the clamping plate 6 firmly clamps the end of the film 12. In the first section, the film 12 is continuously pulled out and flattened from the winding rod 11, achieving effective extension of the roll material. At the same time, the stretching length can be precisely controlled by the stroke of the hydraulic cylinder 18 to meet the needs of different cutting sizes. When the carrier frame 2 moves to the preset cutting position, it stops. At this time, the film 12 is in a fully stretched, flat and wrinkle-free state. Then, the second cylinder 17, which is fixed on one side of the top of the top frame 14, is activated. Its output shaft passes through the top of the top frame 14 and is fixedly connected to the top of the carrier plate 15, driving the carrier plate 15 to move downward in the vertical direction. The cutter 16, which is fixedly connected to the bottom of the carrier plate 15, descends accordingly to vertically cut the film 12 located below, completing a single cutting operation. After the cutting is completed, the second cylinder 17 resets, driving the cutter 16 to rise, the piston rod of the hydraulic cylinder 18 retracts, pulling the carrier frame 2 to reset, and the clamping plate 6 releases the end of the film 12 to prepare for the next feeding.

[0018] Furthermore, a first cylinder 5 is fixedly connected to the top side of the support frame 2 by bolts, and the output shaft of the first cylinder 5 passes through the top of the support frame 2 and is fixedly connected to the top of the clamping plate 6. When the end of the film 12 enters the support frame 2, the first cylinder 5 is activated, and its piston rod extends downward, pushing the clamping plate 6 to overcome the resistance of the elastic element and press down quickly, applying an active clamping force to the film 12. This achieves the effect of automating the clamping action, improving clamping reliability and response speed, and avoiding the problem of insufficient clamping force or lag response caused by relying solely on the elastic element. It ensures that the end of the film 12 is firmly fixed during the stretching process, preventing slippage or displacement.

[0019] Furthermore, compression springs 7 are fixedly connected to both sides of the top of the clamping plate 6, and the top ends of the two compression springs 7 are fixedly connected to the inner top of the bearing frame 2. When the first cylinder 5 drives the clamping plate 6 to press down and clamp the film 12, the compression springs 7 are compressed and store elastic potential energy, providing continuous buffer pressure during the clamping process. This achieves the effect of uniformly distributing the clamping force and preventing rigid compression from damaging the coating on the surface of the film 12. At the same time, when the first cylinder 5 retracts and releases the clamping plate 6, the restoring force of the compression springs 7 assists the clamping plate 6 to quickly reset, improving the stability and repeatability of the clamping and releasing actions.

[0020] Furthermore, a support plate 8 is fixedly connected to the bottom inner side of the frame 1, and a cutting groove 9 is provided on the top of the support plate 8. The cutting groove 9 is located at the bottom of the cutter 16. When the second cylinder 17 drives the cutter 16 to move down to cut the film 12, the blade of the cutter 16 is embedded in the cutting groove 9, which achieves the effect of providing precise guidance and support for the cutter 16 and avoiding deformation or chipping of the blade due to the blade being suspended in the air. At the same time, the presence of the cutting groove 9 enables the cutter 16 to completely cut the film 12 without damaging the worktable below, ensuring the flatness of the cutting edge and the long-term safety of the equipment.

[0021] Furthermore, one end of the winding rod 11 is rotatably connected to the inner wall of the frame 1 via a pivot. A guide frame 10 is fixedly connected to one side of the inner side of the frame 1, and one end of the film 12 passes through the guide frame 10. The guide frame 10 limits and guides its travel path, thereby ensuring that the unwinding direction of the film 12 is consistent and preventing deviation or twisting. This improves the stability and straightness of the feeding, provides a good initial state for subsequent clamping and stretching, and reduces the problem of jamming or wrinkling caused by deviation.

[0022] Furthermore, a slider 3 is fixedly connected to one side of the support frame 2, and the slider 3 is slidably connected to the side wall of the frame 1 through a groove 4. Two telescopic rods 13 are fixedly connected to one side of the support frame 2, and one end of each telescopic rod 13 is fixedly connected to the inner wall of the frame 1. The slider 3 is fixedly connected to one side of the support frame 2, and the slider 3 is embedded in the groove 4 of the side wall of the frame 1 to achieve sliding guidance. At the same time, two telescopic rods 13 are fixedly connected to the other side of the support frame 2, and their free ends are fixedly connected to the inner wall of the frame 1. During the process of the hydraulic cylinder 18 pushing the support frame 2 to move back and forth, the slider 3 slides along the groove 4 to provide the main guiding support, while the telescopic rods 13 play an auxiliary guiding and limiting role, thereby enhancing the movement stability of the support frame 2 and preventing it from shaking or deviating during long-stroke movement. At the same time, the telescopic rods 13 can integrate springs or damping structures to provide reset buffer, extend the service life of the equipment, and ensure smooth and reliable stretching action. In summary: First, the rolled medical dry film 12 is mounted on the winding rod 11 on one side of the inner side of the frame 1. One end of the winding rod 11 is rotatably connected to the inner wall of the frame 1 via a pivot, ensuring that it can rotate freely and smoothly for unwinding. Then, the free end of the film 12 is led out horizontally and passed through the guide frame 10 fixed on one side of the inner side of the frame 1. The guide frame 10 limits and guides the initial travel direction of the film 12 to prevent it from deviating or twisting. Next, the end of the film 12 is inserted into the inner cavity of the support frame 2. The support frame 2 is provided with a clamping plate 6 on the inner side, and its top two sides are connected to the top of the inner side of the support frame 2 through compression springs 7 to form an elastic clamping structure. When the film 12 is in place, the first cylinder 5 fixed on one side of the top of the support frame 2 is activated. Its output shaft passes through the top of the support frame 2 and is fixedly connected to the top of the clamping plate 6, pushing the clamping plate 6 to move downward, compressing the compression spring 7, and applying a stable clamping force to the end of the film 12 by the clamping plate 6 to achieve reliable fixation; after clamping, the hydraulic cylinder 18 fixed on one side of the outer wall of the frame 1 is activated, its output shaft passes through the side wall of the frame 1 and is fixedly connected to one side of the support frame 2, pushing the support frame 2 to move horizontally away from the winding rod 11 along the sliding path inside the frame 1; during this process, the slider 3 fixed on one side of the support frame 2 is embedded in the sliding groove 4 on the side wall of the frame 1 and slides along it, providing the main guide support, while the two telescopic rods 13 fixed on the other side of the support frame 2 extend synchronously, their free ends connecting to the inner wall of the frame 1, and playing a role in... The auxiliary guide and limiting function ensures that the carrier frame 2 maintains a stable linear movement without swaying or tilting during long-stroke movement. As the carrier frame 2 moves, the clamped film 12 is continuously pulled out from the winding rod 11 and flattened, achieving effective extension of the roll material. The stretching length is precisely controlled by the stroke of the hydraulic cylinder 18 to meet different cutting size requirements. When the carrier frame 2 reaches the preset cutting position, it stops moving. At this time, the film 12 is in a fully stretched, flat, and wrinkle-free state. Then, the second cylinder 17, which is fixed to one side of the top of the top frame 14, is activated. Its output shaft passes through the top of the top frame 14 and is fixedly connected to the top of the carrier plate 15, driving the carrier plate 15 and the cutter 16 fixed at the bottom to move vertically downward. The blade of the cutter 16 is precisely... The film 12 is vertically cut into the cutting groove 9 at the top of the bottom support plate 8 inside the frame 1. After cutting, the second cylinder 17 retracts, driving the cutter 16 to rise to the initial position. The piston rod of the hydraulic cylinder 18 retracts, pulling the support frame 2 back to its original position. The first cylinder 5 retracts simultaneously. The clamping plate 6 moves upward under the restoring force of the compression spring 7 to release the end of the film 12, preparing for the next feeding. Through the cooperation of the winding rod 11 and the rotating shaft, the roll material is smoothly rotated and unwound, reducing unwinding resistance and jamming risk. The guide frame 10 effectively guides the initial path of the film 12, preventing it from deviating or wrinkling before entering the support frame 2, thus improving the stability and consistency of feeding.The automatic control of the clamping action is achieved through the cooperation of the first cylinder 5 and the clamping plate 6, improving the clamping response speed and reliability, and avoiding the problem of insufficient clamping force caused by manual intervention or reliance solely on elastic elements. The compression spring 7 provides buffer pressure during clamping, ensuring uniform distribution of clamping force and preventing rigid compression from damaging the photosensitive coating on the film 12 surface. Simultaneously, it assists the clamping plate 6 in rapid resetting during release, improving the repeatability and stability of the action. The hydraulic cylinder 18 drives the carrier frame 2 to move horizontally, achieving active stretching and tensioning of the film 12, significantly improving the flatness before cutting. The cooperation of the slider 3 and the slide groove 4 provides a stable main directional structure for the carrier frame 2, ensuring it maintains straightness during long-stroke movements. Linearity; the telescopic rod 13 further enhances the motion stability of the support frame 2, preventing it from swaying or tilting during reciprocating movement. It can also integrate damping or spring structures for buffering and resetting, extending the equipment's lifespan. The cooperation between the support plate 8 and the cutting groove 9 provides precise guidance and support for the cutter 16, preventing deformation or chipping due to unloaded force, ensuring neat, burr-free cutting edges, and protecting the worktable from damage. This not only achieves the extension, precise stretching, and stable cutting of the film 12, but also significantly improves the automation level and ease of operation of the equipment, effectively solving the technical problems of low cutting efficiency, high scrap rate, and complex operation caused by insufficient extension, unreliable clamping, and unstable material feeding in traditional cutting devices.
