Description

Technical Field

[0001] This utility model relates to the field of medical film printing technology, specifically to a pressure-adjustable medical film output roller. Background Technology

[0002] The medical film output roller is the core component of the medical film printer output system. Its core function is to stably and accurately transport the printed film from inside the equipment to the outside, while ensuring that the film is not damaged during the transmission process and guaranteeing image quality.

[0003] The existing conveyor rollers are mainly composed of a drive roller and a driven roller. When the front end of the film moves between the drive roller and the driven roller, the rotation of the drive roller can be controlled to drive the driven roller to rotate at the same time, thereby driving the film to move, thus ensuring the continuity and smoothness of the film during the transmission process.

[0004] However, because different types of film have different thicknesses, when printing with different films, the distance between the drive roller and the driven roller is fixed, and the pressure on the film is also fixed. This results in thicker films bearing greater pressure, which may damage the film surface and affect the film's performance. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pressure-adjustable medical film output roller, which can solve the existing problems.

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

[0007] An adjustable pressure medical film output roller includes: a mounting frame with a drive roller and a driven roller, and a film pick-up tray; an adjustment assembly mounted on the mounting frame, comprising a lead screw mounted on the mounting frame, a slide plate mounted on the lead screw, an actuating component mounted on the slide plate, a lower connecting plate, and an upper connecting plate; and a support assembly mounted on the lower connecting plate, comprising a pressure roller and a support plate, the pressure roller being mounted on the upper connecting plate and the support plate being mounted on the lower connecting plate.

[0008] Furthermore, the adjustment assembly also includes a drive motor located on one side of the mounting bracket, with a lead screw located at the output end of the drive motor and passing through the mounting bracket.

[0009] Furthermore, sliders are symmetrically arranged on both sides of the skateboard, and grooves are provided on the mounting bracket corresponding to the sliders. The sliders are movably arranged in the grooves, and the slider threads are located on the outside of the lead screw.

[0010] Furthermore, two sets of spring rods are symmetrically arranged on the inner sides of both the lower and upper connecting plates, and one side of each spring rod is connected to the mounting bracket.

[0011] Furthermore, the actuator also includes a drive motor disposed on one side of the slide plate. The output end of the drive motor is provided with a drive wheel, and a belt is meshed with the outer side of the drive wheel. The two sides of the drive roller are disposed through the upper connecting plate, and the two sides of the drive roller are symmetrically provided with second belt gears. The two sides of the driven roller are disposed through the lower connecting plate, and the two sides of the driven roller are symmetrically provided with first belt gears.

[0012] Furthermore, two sets of tensioning pulleys are symmetrically arranged on the mounting frame. The second belt gear and the tensioning pulley are both meshed with the inner side of the belt, and the first belt gear is meshed with the outer side of the belt.

[0013] Furthermore, the support assembly also includes a rotating rod rotatably mounted on one side of the upper connecting plate, and a pressure roller rotatably mounted on the rotating rod.

[0014] Furthermore, multiple sets of rollers are evenly rotated on the support plate.

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

[0016] 1. When conveying films of different specifications, the operator starts the drive motor according to the thickness of the film. This drives the slide plate to move through the rotation of the lead screw. During the movement of the slide plate, the elastic force of the spring rod drives the lower connecting plate and the upper connecting plate to move. At this time, the belt is engaged with the first belt gear and the second belt gear, thereby adjusting the distance between the driving roller and the driven roller. This allows different pressures to be applied to films of different thicknesses.

[0017] 2. To prevent the film from bending due to lack of support during the movement of the film driven by the drive roller and driven roller, a support plate is installed on the lower connecting plate to support the film. Through the cooperation of the rotating rod and the pressure roller, the film can be kept in close contact with the support plate while moving forward, so that the film can be smoothly moved into the film receiving tray, making it easier for the staff to pick up the film.

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.

[0027] like Figure 1 - Figure 5 As shown, this utility model provides a pressure-adjustable medical film output roller, including: a mounting frame 1, a driving roller 3 and a driven roller 4 mounted on the mounting frame 1, and a film pick-up tray 2 mounted on the mounting frame 1; it also includes: an adjustment assembly mounted on the mounting frame 1, the adjustment assembly including a lead screw 16 mounted on the mounting frame 1, a sliding plate 5 mounted on the lead screw 16, and an actuating component mounted on the sliding plate 5; a lower connecting plate 21 and an upper connecting plate 22 mounted on the mounting frame 1; a support assembly mounted on the lower connecting plate 21, the support assembly including a pressure roller 12 and a support plate 13, the pressure roller 12 being mounted on the upper connecting plate 22, and the support plate 13 being mounted on the lower connecting plate 21.

[0028] In the above scheme:

[0029] 1. By starting the drive motor 6, the drive roller 3 and the driven roller 4 can be driven to rotate simultaneously via the belt 8, so that the driven roller 4 can cooperate with the drive roller 3 to drive the film to move smoothly.

[0030] 2. During the process of the lead screw 16 driving the slide plate 5 to move, the elastic force of the spring rod 18 can keep the belt 8 meshing with the first belt gear 9 and the second belt gear 10, thereby realizing the adjustment of the distance between the driving roller 3 and the driven roller 4, so as to realize the adjustment of the pressure of the driving roller 3 and the driven roller 4 on the film of different thicknesses.

[0031] 3. The support plate 13 can support the film, and the cooperation between the pressure roller 12 and the roller 19 allows the film to move along the support plate 13, while also restricting the movement of the film.

[0032] In this embodiment, the adjustment assembly also includes a drive motor 15 disposed on one side of the mounting frame 1, and a lead screw 16 disposed at the output end of the drive motor 15, and the lead screw 16 passes through the mounting frame 1.

[0033] In the above scheme, starting the drive motor 15 makes it easier for the operator to stably control the rotation of the lead screw 16.

[0034] In this embodiment, sliders 14 are symmetrically arranged on both sides of the slide plate 5, and a groove 17 is provided on the mounting bracket 1 corresponding to the slider 14. The slider 14 is movably disposed in the groove 17, and the slider 14 is threaded on the outside of the lead screw 16.

[0035] In the above scheme, the slide plate 5 can be moved by rotating the lead screw 16.

[0036] In this embodiment, two sets of spring rods 18 are symmetrically arranged on the inner sides of both the lower connecting plate 21 and the upper connecting plate 22, and one side of each spring rod 18 is connected to the mounting bracket 1.

[0037] In the above scheme, the distance between the driving roller 3 and the driven roller 4 can be easily adjusted by the elastic force of the spring rod 18.

[0038] In this embodiment, the execution component also includes a drive motor 6 disposed on one side of the slide plate 5. The output end of the drive motor 6 is provided with a drive wheel 7. A belt 8 is meshed with the outer side of the drive wheel 7. The two sides of the drive roller 3 are disposed through the upper connecting plate 22, and the two sides of the drive roller 3 are symmetrically provided with second belt gears 10. The two sides of the driven roller 4 are disposed through the lower connecting plate 21, and the two sides of the driven roller 4 are symmetrically provided with first belt gears 9.

[0039] In the above scheme: the rotation of belt 8 can drive the second belt gear 10 and the first belt gear 9 to rotate, thereby driving the driven roller 4 and the driving roller 3 to rotate simultaneously.

[0040] In this embodiment, two sets of tensioning wheels 11 are symmetrically arranged on the mounting frame 1. The second belt gear 10 and the tensioning wheel 11 are both meshed with the inner side of the belt 8, and the first belt gear 9 is meshed with the outer side of the belt 8.

[0041] In the above scheme, the tensioning wheel 11 facilitates the meshing connection between the outer side of the belt 8 and the first belt gear 9.

[0042] In this embodiment, the support assembly also includes a rotating rod 20 rotatably disposed on one side of the upper connecting plate 22, and a pressure roller 12 rotatably disposed on the rotating rod 20.

[0043] In the above scheme, the setting of the pressure roller 12 can not only apply pressure to the film, but also facilitate the movement of the film.

[0044] In this embodiment, multiple sets of rollers 19 are evenly rotatably arranged on the support plate 13.

[0045] In the above scheme, the rotation of multiple sets of rollers 19 facilitates the movement of the film along the support plate 13.

[0046] In the specific implementation of this embodiment:

[0047] When the printed film needs to be transported from inside the printer, the pressure required for the active roller 3 and driven roller 4 to move films of different thicknesses is different. According to the thickness of the film, the operator starts the drive motor 15, which drives the slider 14 to slide in the slide groove 17 through the rotation of the lead screw 16, thereby moving the slide plate 5. At this time, due to the elasticity of the spring rod 18, the belt 8, the first belt gear 9, the second belt gear 10, and the drive wheel 7 are always engaged. At the same time, the distance between the driven roller 4 and the active roller 3 changes, which causes the pressure of the active roller 3 and the driven roller 4 on the film to change. This ensures that the surface of the film will not be damaged when the active roller 3 and the driven roller 4 move the film. When the film passes between the active roller 3 and the driven roller 4, the support plate 13 supports the film, which can prevent the film from bending. The pressure roller 12 presses the film onto the support plate 13, allowing the film to move along the support plate 13.
