Description

Technical Field

[0001] This utility model relates to the field of medical film printer technology, specifically to a medical film printer anti-deviation film feeding mechanism. Background Technology

[0002] In core imaging diagnostic departments such as radiology and ultrasound, medical film, as the physical carrier of patient image information, has always been an important tool for doctors to quickly obtain key diagnostic information. Its clinical value is reflected in the multi-dimensional and highly timely information transmission process. For example, when using film, the spatial relationship of structures such as bones, soft tissues, and blood vessels can be intuitively displayed by comparing gray levels and density.

[0003] When performing batch printing with a medical film printer, operators typically stack a certain number of films on the feed plate and use the continuous drive of the feed rollers to achieve automated film feeding, thereby significantly improving printing efficiency.

[0004] However, due to the difference in width between different film specifications, when multiple films are stacked, the friction between the films and the traction force of the feed roller may create dynamic interference. Furthermore, the lack of limiting on both sides of the film causes lateral displacement or relative sliding between the stacked films, resulting in the film shifting on the feed plate. This can cause the film to jam when the feed roller moves the film, leading to feed failure and affecting printing efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a film feeding mechanism for medical film printers that prevents film deviation, which can solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A medical film printer anti-deviation film feeding mechanism includes: a printer body, a film feed plate on the printer body, a film body on the film feed plate, and an anti-deviation component, which is mounted on the film feed plate and includes a square rod on the film feed plate, a sliding block on the square rod, a positioning plate on the sliding block, a crank on the sliding block, a connecting plate on the crank, and a roller on the connecting plate; and a cleaning component, which is mounted on the film feed plate and includes a torsion spring on the film feed plate, a mounting plate on the torsion spring, and a cleaning roller on the mounting plate.

[0008] Furthermore, the anti-deviation assembly also includes two sets of sliding blocks symmetrically arranged on the square rod, and an elastic element between the sliding blocks and the feed plate, with the elastic element located on the outside of the square rod.

[0009] Furthermore, the positioning plate is set on one side of the elastic element, and multiple sets of rolling columns are evenly arranged on the outer side of the positioning plate.

[0010] Furthermore, a rotating plate is rotatably mounted on the sliding block, and a locking post is fixedly mounted on one side of the rotating plate. Multiple sets of locking holes are provided on the square rod corresponding to the locking post, and the locking post and locking holes are matched.

[0011] Furthermore, a rotating component is provided on one side of the sliding block corresponding to the crank. The rotating component is rotatably mounted on the sliding block, and the crank and the rotating component are rotatably connected.

[0012] Furthermore, multiple sets of rollers are rotatably mounted on one side of the connecting plate, and a handle is provided on the outer side of the connecting plate.

[0013] Furthermore, the cleaning assembly also includes a rotating shaft disposed on the inner side of the mounting plate, the rotating shaft being rotatably connected to the feed plate, and a torsion spring disposed between the mounting plate and the feed plate, with the torsion spring disposed on the outer side of the rotating shaft.

[0014] Furthermore, the mounting plate is rotatably connected to the cleaning roller, a collection box is provided on the inner side of the mounting plate, and a scraper is provided on one side of the collection box, which is in contact with the cleaning roller.

[0015] Compared with the prior art, the beneficial effects of this utility model include:

[0016] 1. When the film body needs to be placed on the film feed plate, the operator presses or pulls the connecting plate according to the width of the film body, so that the crank drives the sliding block to move on the square rod. At this time, the positioning plate also moves with the sliding block, so that the distance between the two sets of positioning plates corresponds exactly to the width of the film body. This can prevent the film body from swaying left and right on the film feed plate. By placing the connecting plate above the film body, the vertical direction of the film body can be restricted, which can effectively prevent the film body from shifting on the film feed plate.

[0017] 2. To prevent dust on the film surface from affecting the printing effect, the torsion spring keeps the cleaning roller in constant contact with the film. The movement of the film causes the cleaning roller to clean the surface of the film. At the same time, the scraper removes the dust from the cleaning roller and causes the dust to fall into the collection box for centralized disposal by the staff. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1 - Figure 5As shown, this utility model provides a medical film printer anti-deviation film feeding mechanism, including: a printer body 1, a film feeding plate 2 on the printer body 1, a film body 3 on the film feeding plate 2, and an anti-deviation component on the film feeding plate 2. The anti-deviation component includes a square rod 4 on the film feeding plate 2, a sliding block 20 on the square rod 4, a positioning plate 6 on the sliding block 20, a crank 7 on the sliding block 20, a connecting plate 8 on the crank 7, and a roller 9 on the connecting plate 8.

[0027] A cleaning assembly is provided on the feed plate 2. The cleaning assembly includes a torsion spring 15 provided on the feed plate 2, a mounting plate 5 provided on the torsion spring 15, and a cleaning roller 11 provided on the mounting plate 5.

[0028] In the above scheme:

[0029] 1. By controlling the movement of the connecting plate 8, the crank 7 can drive the two sets of sliding blocks 20 to move, which in turn can drive the positioning plate 6 to move, so that the distance between the two sets of positioning plates 6 matches the width of the film body 3, thereby preventing the film body 3 from shifting left and right.

[0030] 2. The vertical movement of the film body 3 can be limited by the cooperation of the connecting plate 8 and the roller 9;

[0031] 3. The cleaning roller 11 can clean the dust on the surface of the film body 3, thus preventing dust from affecting the subsequent printing effect.

[0032] In this embodiment, the anti-deviation component also includes two sets of sliding blocks 20 symmetrically arranged on the square rod 4, and an elastic element 21 between the sliding block 20 and the feed plate 2, the elastic element 21 being arranged on the outside of the square rod 4.

[0033] In the above scheme, the elastic force of the elastic element 21 facilitates the positioning plate 6 to quickly position the film body 3.

[0034] In this embodiment, the positioning plate 6 is disposed on one side of the elastic member 21, and multiple sets of rolling columns 22 are evenly disposed on the outer side of the positioning plate 6.

[0035] In the above solution, the friction between the positioning plate 6 and the film body 3 is reduced by the setting of the rolling column 22, allowing the film body 3 to move smoothly.

[0036] In this embodiment, a rotating plate 16 is rotatably mounted on the sliding block 20, and a locking post 17 is fixedly mounted on one side of the rotating plate 16. The square rod 4 is provided with multiple sets of locking holes 18 corresponding to the locking post 17, and the locking post 17 matches the locking hole 18.

[0037] In the above scheme, the position of the positioning plate 6 can be fixed by the cooperation of the card hole 18 and the card post 17, so as to avoid the remaining film body 3 on the film feeding plate 2 being squeezed and damaged when the film body 3 is used more.

[0038] In this embodiment, a rotating member 19 is provided on one side of the sliding block 20 corresponding to the crank 7. The rotating member 19 is rotatably mounted on the sliding block 20, and the crank 7 and the rotating member 19 are rotatably connected.

[0039] In the above scheme, the crank 7 is designed to facilitate the simultaneous control of the movement of the two sets of sliding blocks 20 by the operator.

[0040] In this embodiment, a plurality of rollers 9 are rotatably provided on one side of the connecting plate 8, and a handle 10 is provided on the outer side of the connecting plate 8.

[0041] In the above scheme, the handle 10 makes it easier for staff to control the connecting plate 8.

[0042] In this embodiment, the cleaning assembly also includes a rotating shaft 14 disposed on the inner side of the mounting plate 5, the rotating shaft 14 being rotatably connected to the feed plate 2, and a torsion spring 15 disposed between the mounting plate 5 and the feed plate 2, and the torsion spring 15 being disposed on the outer side of the rotating shaft 14.

[0043] In the above scheme, the spring force of the torsion spring 15 can drive the cleaning roller 11 to always keep in contact with the surface of the film body 3.

[0044] In this embodiment, the mounting plate 5 is rotatably connected to the cleaning roller 11. A collection box 12 is provided on the inner side of the mounting plate 5, and a scraper 13 is provided on one side of the collection box 12. The scraper 13 is in contact with the cleaning roller 11.

[0045] In the above scheme, the dust on the cleaning roller 11 can be scraped off by the scraper 13.

[0046] In this embodiment, when a certain number of film bodies 3 are stacked on the feed plate 2, the operator, based on the width of the film bodies 3, presses or pulls the handle 10 to rotate the connecting plate 8 and the crank 7. This simultaneously moves the two sets of sliding blocks 20 on the square rod 4. Then, the film bodies 3 are placed on the feed plate 2. At this time, the handle 10 is released, and the elastic force of the elastic element 21 can drive the positioning plate 6 to restrict the film bodies 3 to the center position of the feed plate 2. Then, by rotating the rotating plate 16, the locking pin 17 is inserted into the corresponding locking hole 18, thereby fixing the position of the positioning plate 6. This prevents the positioning plate 6 from being squeezed when a small number of film bodies 3 remain on the feed plate 2. The film body 3 is then placed on the surface of the film body 3 by placing the connecting plate 8. At this time, the roller 9 contacts the film body 3, allowing the film body 3 to move smoothly. As the film body 3 moves into the printer body 1, the spring force of the torsion spring 15 ensures that the cleaning roller 11 remains in contact with the film body 3. This allows the cleaning roller 11 to rotate as the film body 3 moves, cleaning the surface of the film body 3 and removing dust from the surface. During the rotation of the cleaning roller 11, the scraper 13 scrapes the dust and impurities on the cleaning roller 11 into the collection box 12, thus enabling the cleaning roller 11 to continuously clean the dust on the film body 3.
