Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, and particularly relates to a film supply cassette with an anti-displacement device and a medical film printing device. Background Technique

[0002] Medical film printing equipment is an indispensable imaging instrument in the medical field. It plays a key role in converting digital medical images into physical printed images. This conversion not only provides doctors with detailed visual materials for more accurate diagnosis of diseases and formulation of treatment plans, but also preserves important medical records for patients. As the main output medium of medical printing equipment, the quality and state of the film directly affect the effect of the printed image. Usually, dozens to hundreds of films are stacked in a film supply cassette, which not only ensures the continuity of printing but also avoids the trouble of frequent replacement. As a storage container for films, the design of the film supply cassette needs to consider ease of use and convenience. The design of the drawer-type film supply cassette enables the cassette to be easily taken out or inserted into the printing equipment, which not only simplifies the process of loading and replacing films but also improves work efficiency, meeting the needs of medical institutions for high-efficiency and high-quality printed images.

[0003] However, the design of the drawer-type film supply cassette has some drawbacks. For example, the utility model patent CN215100813U discloses a drawer film cassette. As Figure 1 shown, when the user finishes loading a stack of films and pushes the film supply cassette forcefully into the printer, due to the smooth and low-friction characteristics of the films themselves, the friction between the films is not sufficient to resist inertia, and one or more top films in a stack of films will slide into the film conveying channel from the direction of the front side plate of the film supply cassette. That is, before the printing task is executed, there are already films in the conveying channel connected to the film supply cassette. Once the printing task is executed, it will cause the conveying channel to be blocked and unable to execute printing, or cause problems such as film double-sheet feeding, continuous sheet feeding, and / or inclined feeding, resulting in problems such as missing information in the printed image. Once the above problems occur, it not only causes frequent power-on for maintenance, reducing the working efficiency of the printing equipment, but also may lead to medical accidents such as misdiagnosis and missed diagnosis, causing adverse consequences such as legal disputes. Therefore, it is urgently necessary and realistic to solve the problem of preventing films from slipping into the conveying channel due to inertia when the drawer-type film supply cassette is inserted into the printing equipment.

[0004] In response to this, the utility model patent CN210377018U discloses a transmission and sheet-splitting structure of a medical dry film recording device. As Figure 2 shown, a dialing device 9 is added to the front side wall of the drawer-type film supply cassette, and the utility model patent CN216101096U discloses a film storage cassette and a film printer. As Figure 3As shown in the figure, a flexible bump 12 is added to the front side wall of the drawer-type film supply cassette to solve the above problems. This design can, on the one hand, reduce the occurrence of double-sheet problems during film slicing, and on the other hand, prevent the top film of a stack of films from entering the conveying channel due to inertia. However, the above design of the drawer-type film supply cassette is only applicable to printers with a suction cup film rubbing type film supply, and cannot be adapted to film rubbing type film supply printers, which has obvious limitations. Moreover, printers with a suction cup film rubbing type film supply adopt a film slicing and conveying scheme that combines mechanisms such as suction cups, fans, paddles or separation blocks with conveying rollers. The overall mechanism is complex, and the requirements for the processing and assembly accuracy of components are high, which increases the purchase and maintenance costs. Moreover, since the overall mechanism is adjacent to the film supply cassette, considering scenarios such as film loading, slicing and conveying, in order to avoid interference, the effective accommodation space of the film supply cassette is inevitably compressed, resulting in an increase in the frequency of film loading, and the practicability and economy are poor.

[0032] Embodiment 1

[0033] Referring to Figures 4-7 , the film supply cassette 1 is a disk-shaped component integrally formed by resin with a rectangular bottom plate 14 that forms a film storage space and a pair of front walls 11, side walls 12, and a rear wall 13 that surround the four faces of the bottom plate 14. A pair of side walls 12 are respectively arranged at both ends in the width direction of the film supply cassette 1. Linear sliding grooves are formed on the outer side surfaces of the side walls 12 along the length direction of the film supply cassette 1 for sliding connection with the sliding rails of the printing device accommodating part. The front wall 11 is arranged at the forward side end of the film supply cassette 1 in the direction of being fed into the printing device. After the film supply cassette 1 is fed into the accommodating part of the printing device, the front wall 11 contacts the printing device main body, thereby completing the connection of the conveying channel. In addition, the width direction refers to the direction orthogonal to the direction in which the film is sent out of the film supply cassette and the film stacking direction, and the length direction refers to the direction parallel to the direction in which the film is sent out of the film supply cassette and orthogonal to the film stacking direction. A rear wall 13 is arranged at one end of the upper surface of the film supply cassette 1 corresponding to the front wall 11. The rear wall 13 has two sections separated by a retaining portion 44 in the width direction, and the two sections are respectively connected to the adjacent side walls 12. Preferably, a pair of side walls 12, the front wall 11, and the rear wall 13 have the same height and the same thickness, so that it is easier to be integrally formed.

[0034] The anti-displacement device includes a pressing plate part 2, a locking release part 3, and a limiting part 4. The pressing plate part 2 is pivotally connected to both end faces of the front wall 11 along the width direction of the film supply cassette 1, and is used to open or close the film feeding port of the film supply cassette 1; the locking release part 3 is fixedly connected to the shelf plate 5 of the printing device accommodating part, and is used to make the pressing plate part 2 rotate counterclockwise to open the film feeding port when the film supply cassette 1 is fed into the preset position of the printing device accommodating part, and make the pressing plate part 2 rotate clockwise to close the film feeding port when the film supply cassette 1 disengages from the preset position; the limiting part 4 is arranged on the upper surface of the bottom plate 14 to prevent the film from moving due to inertia in the width direction.

[0035] The pressing plate part 2 includes a pressing plate 21 and a counterweight shaft 22. The pressing plate 21 is made of resin and is a long "U"-shaped integrally formed structural part with two parallel ear plates 211 and a bridge plate 212. The two ear plates 211 are respectively pivotally connected to both end faces of the front wall 11 along the width direction. The bridge plate 212 is generally in the shape of a long strip rectangle, and a groove 2121 is provided on its upper end face along the width direction. A plurality of ribs are arranged at intervals on the upper surface of the groove 2121; the counterweight shaft 22 is made of metal and is in the shape of a long strip cylinder, and is detachably buckled with a plurality of ribs along the width direction. When the pressing plate part 2 is acted on by an external force, it can rotate counterclockwise around the pivot axis of the ear plate 211 and the front wall 11, and its bridge plate 212 is disengaged from the front wall 11 and maintains a preset gap. When the film feeding port of the film supply cassette 1 is opened (open state), the film supply cassette 1 is communicated with the conveying channel of the printing device. When a printing task is executed, a film splitting device arranged above the front wall 11 in the printing device will send the film into the conveying channel of the printing device along the film feeding port. Due to the setting of the counterweight shaft 22, the pressing plate part 2 can rotate clockwise around the pivot axis of the ear plate 211 and the front wall 11 under the action of its own gravity until the bridge plate 212 abuts against the front wall 11 and closes the film feeding port of the film supply cassette (sealing state). At this time, the film supply cassette is disconnected from the conveying channel of the printing device. Combining the above description, that is, at this time, it is possible to prevent the top film of a stack of films in the film supply cassette 1 from entering the conveying channel due to inertia.

[0036] The locking release part 3 is slidably connected to the side wall 12 by means of a linear slide rail and a chute, and includes a connecting block 31, an unlocking block 32 and a guiding block 33. The locking release part 3 is made of resin and is a strip-shaped integrally formed structural component. On the end face of the guiding block 33 adjacent to the side wall 12, a slide rail is provided along the length direction, which is slidably connected to the chute provided on the side wall 12 to ensure that the film supply cassette 1 can be smoothly withdrawn and inserted into the printing device; on the end face of the guiding block 33 away from the side wall 12, a number of rectangular grooves are spaced apart for weight reduction; on the end face of the guiding block 33 away from the side wall 12, rectangular connecting blocks are also spaced apart, and the connecting blocks are used for fixedly connecting with the shelf plate 5 of the accommodating part of the printing device to support the film supply cassette 1; the unlocking block 32 is in the shape of a horizontally inverted trapezoidal block and is connected to the end face of the guiding block 33 along the length direction. When the film supply cassette 1 is inserted into the accommodating part of the printing device, the lower edge of the ear plate 211 slides and abuts against the upper end face of the guiding block 33, and the guiding block 33 will not apply an upward force to cause displacement or rotation to the ear plate 211. Under the action of its own gravity, the pressing plate part 2 keeps the bridge plate 212 in contact with the front wall 11, and at this time the film supply port is in a sealed state; as the film supply cassette continues to be inserted, until the lower edge of the ear plate 211 slides and abuts against the unlocking block 32, due to the unlocking block 32 being in the shape of a horizontally inverted trapezoidal block, the bridge plate 212 rotates counterclockwise upward around the pivot axis of the ear plate 211 and the front wall 11, the bridge plate 212 is separated from the front wall 11 and the film supply port gradually opens; when the film supply cassette 1 is completely inserted into the printing device, that is, when it reaches the preset position, the gap between the bridge plate 212 and the front wall 11 reaches the preset value and remains, and the film supply port is in an open state. When the film supply cassette 1 is withdrawn from the printing device, the above process is reversed, and the film supply port changes from the open state to the sealed state, which will not be elaborated.

[0037] In order to correspond to various sizes of films and prevent the films from moving due to inertia in the width direction, a limiting part 4 is provided in the film supply cassette. The limiting part 4 includes a first frame body 41, a second frame body 42, a locking part 43 and a retaining part 44 that can move in the width direction relative to the bottom plate 14 of the film supply cassette.

[0038] The first frame body 41 includes a first limiting part 411 provided on one side of the bottom plate 14 along the width direction and a first rack part 412 extending from one side along the width direction towards the center. The first limiting part 411 is slidably connected to the bottom plate 14, and the first limiting part 411 is detachably connected to the first rack part 412.

[0039] Correspondingly, the second frame body 42 includes a second limiting part 421 provided on the other side of the bottom plate 14 along the width direction and a second rack part 422 extending from the side opposite to the first rack part 412 towards the center. The second limiting part 421 is slidably connected to the bottom plate 14, and the second limiting part 421 is detachably connected to the second rack part 422.

[0040] The second rack portion 422 is disposed parallel and opposite to the first rack portion 412. A gear 45 is provided between the first rack portion 412 and the second rack portion 422. The gear 45 is meshed and connected to the first rack portion 412 and the second rack portion 422. The rotation axis of the gear 45 is disposed at the bottom. Preferably, the axis of the rotation axis of the gear is orthogonal to the center line of the film supply cassette 1 along the feeding direction and is located on the side close to the front wall 11.

[0041] The locking portion 43 includes a fastening bolt 431 for locking and releasing the first frame body 41 and the second frame body 42. When the fastening bolt 431 is adjusted downward, the lower part of the bolt 431 is in close contact with the upper surface of the second rack portion 422, thereby locking the first frame body 41 and the second frame body 42. On the contrary, when the fastening bolt 431 is adjusted upward, the first frame body 41 and the second frame body 42 are released.

[0042] One retreat stop portion 44 is centrally provided on the upper surface of the bottom plate 14 on the side where the rear wall 13 is located. Cooperating with the use of the first frame body 41, the second frame body 42 and the locking portion 43, it can be used to limit the displacement of the film in the length direction, prevent the film from sliding out or moving from the film supply cassette 1 when the film supply cassette 1 is carried or tilted along with the printing device, and can also meet the loading of films with different specifications and sizes.
