Description

Technical Field

[0001] This utility model relates to the technical field of medical film processing equipment, and in particular to a cleaning device based on medical dry film processing. Background Technology

[0002] Medical dry film is a high-precision imaging material that can output medical images via laser or thermal methods without chemical processing, and is widely used in medical diagnostic scenarios such as radiology, ultrasound, and MRI. Because its imaging layer is extremely sensitive to surface cleanliness, even minute dust, particles, or fingerprints can cause defects such as black spots, streaks, or localized blurring in the image, seriously affecting the accuracy of doctors' interpretations and the quality of clinical diagnosis. Therefore, during the production, cutting, and packaging of medical dry film, efficient, clean, and non-destructive cleaning of the film surface is essential to ensure the imaging quality and reliability of the final product. For this reason, specialized cleaning equipment has become an indispensable key component of automated medical film production lines.

[0003] Existing technologies, such as utility model patent CN 220027900 U, disclose a cleaning device for the production of medical dry films. This device, by setting up a structure such as a guide roller, mounting base, wiping cloth, spring and guide sleeve, makes the film come into contact with the elastically pressed wiping cloth during the transmission process, thereby wiping away the dust on the surface.

[0004] Although the solution addresses the basic needs of online film cleaning, it still faces significant operational inconvenience in practical applications: the device is equipped with only a single set of wiping cloth components, and after long-term continuous operation, the wiping cloth is prone to becoming saturated with dust and losing its cleaning ability, resulting in incomplete cleaning of subsequent films. Due to the lack of a quick replacement structure, the machine must be stopped and the mounting frame and guide sleeve must be disassembled when the wiping cloth needs to be replaced, which is cumbersome and time-consuming, significantly reducing the overall production efficiency of the line. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device based on medical dry film processing, which solves the problem that in the prior art, the device is only equipped with a single set of wiping cloth components. After long-term continuous operation, the wiping cloth is easily saturated with dust and loses its cleaning ability, resulting in incomplete cleaning of subsequent films. Due to the lack of a quick replacement structure, when the wiping cloth needs to be replaced, the machine must be stopped and the mounting frame and guide sleeve must be disassembled, which is cumbersome and time-consuming, and significantly reduces the overall production efficiency.

[0006] To achieve the above objectives, this utility model provides a cleaning device based on medical dry film processing, including a base and two vertical plates fixedly connected to the top of the base. A guide roller is rotatably connected between the two vertical plates. A top frame is provided on the top of the two vertical plates. The bottom sides of the top frame are slidably engaged with the vertical plates through sliding structures. A vertical lifting structure is provided on one side of the top of the base to cooperate with the top frame. The top frame is internally connected to a rotating rod. The top and bottom of the rotating rod are detachably connected to mounting plates via a connecting structure. Wiping cloths that cooperate with guide rollers are detachably connected to the two mounting plates on opposite sides. One end of the rotating rod rotatably passes through the side wall of the top frame and is connected to a positioning structure. The positioning structure is detachably connected to the side wall of the top frame.

[0007] The guide roller is provided with scrapers on both sides, and a side plate is fixedly connected to one side of the scraper. Both ends of the side plate are fixedly connected to the adjacent vertical plate with bolts.

[0008] The sliding structure includes a lifting groove on the top of the vertical plate, and the bottom of the top frame is slidably connected to the inside of the lifting groove.

[0009] The vertical lifting structure includes a lifting cylinder installed on the top of the base. The output end of the lifting cylinder is connected to a fixing plate, and one side of the fixing plate is connected to the top frame.

[0010] The positioning structure includes a circular plate fixedly connected to one end of the rotating rod and a positioning plate fixedly connected to one side of the circular plate. A positioning screw with one end threaded through the positioning plate is provided on one side of the positioning plate. Several positioning holes adapted to the positioning screw are opened on the side wall of the top frame.

[0011] The circular plate has a rotating handle on one side, and the rotating handle is fixedly connected to the circular plate with bolts.

[0012] This utility model discloses a cleaning device based on medical dry film processing. This technical solution effectively solves the problems of inconvenient replacement, reduced cleaning quality, and long downtime in existing cleaning devices that only have a single set of wiping cloths. By installing detachable mounting plates and wiping cloths at both the top and bottom of the rotating rod, a coaxial symmetrical layout of two cleaning units is achieved. This allows for rapid switching to a spare set of wiping cloths after one set is used, significantly improving the device's continuous operation capability. The rotational engagement between the rotating rod and the top frame, combined with the positioning structure design, allows operators to quickly switch wiping cloth positions, avoiding the need to disassemble the mounting frame and guide sleeve in traditional methods. The simplified operation reduces manual intervention and maintenance time, improving production efficiency. Simultaneously, since each use of the cleaning cloth is pre-replaced and clean, it avoids the risk of secondary contamination or scratches caused by overuse, ensuring the cleanliness consistency and surface integrity of each batch of film. The combination of the vertical lifting and sliding structures allows the top frame to be raised and lowered as a whole, facilitating not only the adjustment of the pressure of the cleaning cloth on the film to accommodate dry films of different thicknesses, but also allowing for complete separation of the cleaning components for maintenance or large-scale cloth replacement when needed. All connections involving cloth installation and fixing are detachable, further enhancing the maintainability and operational flexibility of the equipment. Attached Figure Description

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Example 1 Please see Figure 1-5 As shown, a cleaning device based on medical dry film processing in this embodiment includes a base 1 and two vertical plates 4 fixedly connected to the top of the base 1. A guide roller 3 is rotatably connected between the two vertical plates 4. A top frame 2 is provided on the top of the two vertical plates 4. Both sides of the bottom of the top frame 2 are slidably engaged with the vertical plates 4 through a sliding structure. A vertical lifting structure that engages with the top frame 2 is provided on one side of the top of the base 1. The top frame 2 is internally connected to a rotating rod 5. The top and bottom of the rotating rod 5 are detachably connected to mounting plates 6 via a connecting structure. The two mounting plates 6 are detachably connected to a wiping cloth 7 that cooperates with the guide roller 3 on opposite sides. One end of the rotating rod 5 rotates through the side wall of the top frame 2 and is connected to a positioning structure. The positioning structure is detachably connected to the side wall of the top frame 2. The connecting structure includes a connecting frame 17. One side of the connecting frame 17 is bolted to the mounting plate 6, and the other end is bolted to the rotating rod 5.

[0022] When surface cleaning of medical dry films is required, the top frame 2 is first driven downward along the sliding structure on the vertical plate 4 by the vertical lifting structure. This reduces the gap between the mounting plate 6 connected to the bottom of the rotating rod 5 installed in the top frame 2 and the wiping cloth 7 on it, and the guide roller 3 on the base 1. This clamps the film to be cleaned between the guide roller 3 and the wiping cloth 7 below. The film is then horizontally transported along the surface of the guide roller 3 under the traction of the production line. Its upper and lower surfaces contact the guide roller 3 and the wiping cloth 7 respectively. During this process, dust, particles, and other contaminants are effectively wiped away by the wiping cloth 7. As the equipment continues to operate, the wiping cloth 7 gradually becomes saturated with dust due to prolonged contact with the film, reducing its cleaning effect. At this point, it can be cleaned by... The vertical lifting structure moves the top frame 2 upwards, causing the wiping cloth 7 on that side to detach from the film. The operator then manually rotates the rotating rod 5 180 degrees within the top frame 2. A positioning structure at one end of the rotating rod 5 locks the rotated position, ensuring its stability. At this point, the other mounting plate 6 and the unused clean wiping cloth 7, originally located at the top, move to the lower working position. The vertical lifting structure is then activated again, driving the top frame 2 downwards, allowing the newly installed wiping cloth 7 to press firmly against the film surface again, continuing the cleaning task. The entire replacement process requires no disassembly of any fixed parts or prolonged downtime, enabling rapid switching of the wiping cloth 7 and ensuring the continuity of cleaning operations.

[0023] Example 2 Please see Figure 1-5 As shown in this embodiment, a cleaning device based on medical dry film processing is provided on both sides of the guide roller 3. A scraper 10 is provided on one side of the scraper 10, and a side plate 9 is fixedly connected to one side of the scraper 10. Both ends of the side plate 9 are bolted to the adjacent vertical plate 4. Specifically, through the cooperation of the scraper 10 provided on both sides of the guide roller 3 with the side plate 9 and the vertical plate 4, the scraper 10 is fixed on the side plate 9, and the side plate 9 is rigidly connected to the vertical plate 4 by bolts. During the process of medical dry film being transported along the surface of the guide roller 3, the scraper 10 physically scrapes away the dust and debris that may be carried on the edge of the film, preventing them from entering the cleaning area with the film or adhering to the surface of the guide roller 3. This achieves the effect of avoiding secondary contamination of the film surface by impurities, improving the overall cleaning effect, and protecting the surface of the guide roller 3 from scratches.

[0024] The vertical lifting structure includes a lifting cylinder 12 installed on the top of the base 1. The output end of the lifting cylinder 12 is connected to a fixing plate 11. One side of the fixing plate 11 is connected to the top frame 2. Specifically, through the cooperation of the lifting cylinder 12 installed on the base 1, the fixing plate 11 connected to its output end, and the top frame 2, after the lifting cylinder 12 is started, it pushes the fixing plate 11 to drive the top frame 2 to rise or fall along the lifting groove 8, thereby realizing the automated vertical displacement control of the top frame 2. This achieves the effect of accurately adjusting the clamping force between the wiping cloth 7 and the guide roller 3, adapting to the cleaning needs of films of different thicknesses, and improving the automation level and ease of operation of the equipment.

[0025] Example 3 Please see Figure 1-5 As shown in the figure, this embodiment of a cleaning device based on medical dry film processing includes a sliding structure comprising a lifting groove 8 opened at the top of a vertical plate 4. The bottom of the top frame 2 is slidably connected to the inside of the lifting groove 8. Specifically, through the cooperation between the lifting groove 8 opened at the top of the vertical plate 4 and the bottom of the top frame 2, the two sides of the top frame 2 are embedded in the lifting groove 8 and slide up and down along its inner wall. When the vertical lifting structure drives the top frame 2 to move, the lifting groove 8 provides stable guiding support for the top frame 2, restricting its horizontal displacement, thereby ensuring the smooth lifting process of the top frame 2, preventing uneven contact pressure between the wiping cloth 7 and the film due to shaking, and ensuring consistent cleaning.

[0026] The positioning structure includes a circular plate 16 fixedly connected to one end of the rotating rod 5 and a positioning plate 13 fixedly connected to one side of the circular plate 16. A positioning screw 14 with one end threaded through the positioning plate 13 is provided on one side of the positioning plate 13. Several positioning holes adapted to the positioning screw 14 are opened on the side wall of the top frame 2. Specifically, through the cooperation of the circular plate 16, positioning plate 13, positioning screw 14 connected to the end of the rotating rod 5 and the multiple positioning holes on the side wall of the top frame 2, when the rotating rod 5 rotates 180 degrees to switch the wiping cloth 7 position, the positioning screw 14 is screwed into the corresponding positioning hole, so that the positioning plate 13 and the top frame 2 form a detachable rigid connection, thereby locking the current angle position of the rotating rod 5. This achieves the effect of ensuring the accurate working position of the wiping cloth 7 after rotation, preventing the rotating rod 5 from rotating unexpectedly due to vibration during operation, and ensuring the stability of equipment operation and cleaning reliability.

[0027] A rotating handle 15 is provided on one side of the circular plate 16. The rotating handle 15 is bolted to the circular plate 16. Specifically, through the cooperation of the rotating handle 15 on one side of the circular plate 16 and the circular plate 16 being bolted together, the operator can directly hold the rotating handle 15 to apply torque, causing the circular plate 16 and the rotating rod 5 fixed thereto to rotate synchronously, realizing the manual and quick switching of the top and bottom wiping cloth 7 stations. This achieves the effects of facilitating manual operation, reducing the labor intensity of switching, and improving the efficiency of wiping cloth 7 replacement.

[0028] When surface cleaning of medical dry films is required, first activate the lifting cylinder 12 installed on top of the base 1. Its output end pushes the fixed plate 11, which is fixedly connected. Since one side of the fixed plate 11 is connected to the top frame 2, it drives the entire top frame 2 to slide up or down along the lifting grooves 8 opened on the top of the two vertical plates 4. At this time, the bottom sides of the top frame 2 slide with the vertical plates 4 through the lifting grooves 8, ensuring that the lifting process is smooth and without deviation. When cleaning is performed, the lifting cylinder 12 drives the top frame 2 to move downward, so that the mounting plate 6 connected to the bottom of the rotating rod 5 located inside the top frame 2 and the detachable cleaning device on it... The cloth 7 gradually approaches and presses against the medical dry film placed on the guide roller 3, which is rotatably connected between the two vertical plates 4, thereby stably clamping the film between the guide roller 3 and the wiping cloth 7 below. Under the traction force of the production line, the film is horizontally transported along the surface of the guide roller 3, with its lower surface in contact with the guide roller 3 and its upper surface fully adhering to and sliding relative to the pressed-down wiping cloth 7, achieving effective wiping and removal of dust, particles, and other contaminants from both sides of the film. During this process, the scrapers 10 set on both sides of the guide roller 3 are rigidly connected to the adjacent vertical plate 4 by bolts through the side plate 9 fixed on one side. The scrapers 10 physically scrape away the debris or dust carried by the edges of the film. To prevent impurities from spreading to the cleaning area or adhering to the surface of the guide roller 3 and causing cross-contamination; as the equipment continues to run, the currently working wiping cloth 7 gradually becomes saturated due to continuous dust absorption, and its cleaning ability decreases. At this time, the lifting cylinder 12 is activated again, and the top frame 2 is moved upward through the fixed plate 11, so that the wiping cloth 7 on this side is separated from the film and the cleaning action stops; then the operator manually holds the rotating handle 15 fixed to one side of the circular plate 16, and the rotating handle 15 is fastened to the circular plate 16 with bolts, and the rotational torque is applied to drive the circular plate 16 and the rotating rod 5 fixed to it to rotate 180 degrees within the top frame 2, so that the previously unused cloth at the top is rotated. Another set of mounting plates 6 and clean cloths 7 are rotated to the lower working position; after being rotated into place, one end of the positioning screw 14 set on the positioning plate 13 is screwed into the positioning hole at the corresponding position on the side wall of the top frame 2 to achieve detachable locking between the positioning plate 13 and the top frame 2, thereby fixing the angle position of the rotating rod 5 and preventing loosening or displacement during operation; finally, the lifting cylinder 12 is started again to drive the top frame 2 to move down, so that the newly replaced cloths 7 can press the film surface again and continue to perform the cleaning task. The entire replacement process does not require disassembling any major structural components, and the quick switching of the dual-station cloths 7 can be completed, ensuring the continuity and efficiency of the cleaning operation.

[0029] This technical solution uses base 1 as the overall support foundation, providing an installation benchmark for all structures. Two vertical plates 4 are fixedly connected to the top of base 1 to support guide rollers 3 and provide lifting guidance for the top frame 2. The guide rollers 3 are rotatably connected between the two vertical plates 4 to achieve smooth conveying of the film and support of the lower surface. The top frame 2 is set on top of the vertical plates 4 and slides with the lifting grooves 8 on the vertical plates 4 through its bottom sides to ensure stable movement trajectory during lifting. The lifting cylinder 12 serves as the power source for the vertical lifting structure, driving the top frame 2 to achieve automated lifting by pushing the fixed plate 11, improving the ease of operation and the accuracy of clamping force adjustment. The rotating rod 5 is rotatably connected inside the top frame 2, and its top and bottom are both equipped with mounting plates 6 through detachable connection structures for easy maintenance and replacement. The side of the mounting plates 6 that is far apart from each other is detachable. The detachable wiping cloth 7 allows for individual replacement based on usage, avoiding resource waste. One end of the rotating rod 5 passes through the side wall of the top frame 2 and connects to the positioning structure, which consists of a circular plate 16, a positioning plate 13, and a positioning screw 14. Combined with multiple positioning holes on the side wall of the top frame 2, it can achieve precise angle positioning and secure locking after a 180-degree rotation, ensuring stable operation. The rotating handle 15 is fixed to one side of the circular plate 16, facilitating manual rotation and reducing labor intensity. The scraper 10 is located on both sides of the guide roller 3 and is bolted to the vertical plate 4 via the side plate 9, enabling pre-cleaning of contaminants on the film edges and preventing secondary contamination. All detachable connection designs, including the mounting plate 6 and rotating rod 5, the wiping cloth 7 and mounting plate 6, and the rotating handle 15 and circular plate 16, enhance the equipment's maintenance convenience and operational flexibility.
