Referring to fig. 1 to fig. 3, in an embodiment, the sheet feeding device 10 includes a sheet cassette magazine 100, a driving power source 200, a picking mechanism 300, and an abutting mechanism 400. Wherein the magazine 100 is used to load a plurality of films 20; the pick-up mechanism 300 is in contact with the first portion 21 of the film 20, and the driving power source 200 drives the pick-up mechanism 300 to feed the film 20 into the magazine 31 of the printer 30; and the abutting mechanism 400 is disposed in the film cartridge compartment 100 and abuts against the second portion 22 of the film 20, and the driving power source 200 drives the abutting mechanism 400 to apply a paper feeding supporting force F to the film 20, so that the film 20 in the film cartridge compartment 100 smoothly enters the film storage compartment 31.

Specifically, the pickup mechanism 300 uses friction in contact with the first portion 21 of the film 20 to feed the film 20 into the magazine 31 of the printer 30. However, during the film 20 being transported, due to the gravity of the film 20 itself, the film 20 to be transported at the back exerts a pressure on the film 20 being transported at the front, so that the film 20 at the front cannot naturally fall into the magazine 31 of the printer 30 by gravity. Therefore, the second portion 22 of the film 20 to be fed at the back is pressed by the pressing mechanism 400 to exert a feeding force F toward the back or upward direction to cancel the pressing force on the film 20 at the front, so that the film 20 can be continuously fed into the magazine 31. This effectively solves the problem of cards in the film 20 transport process and is simple in construction and easy to implement.

Further, referring to fig. 1 and 3, in an embodiment, the pickup mechanism 300 includes a driving gear 310 and a pickup roller 320, the driving gear 310 includes a first rotating shaft 311 and is driven to rotate by the driving power source 200, the pickup roller 320 is mounted on the first rotating shaft 311, the pickup roller 320 contacts with the first portion 21, the abutting mechanism 400 includes a driven gear 410 and an abutting roller 420, the driven gear 410 includes a second rotating shaft 411 and is linked with the driving gear 200 to realize reverse rotation, the abutting roller 420 is mounted on the second rotating shaft 411, and the abutting roller 420 is disposed in the magazine 100 and abuts against the second portion 22.

Specifically, in the present embodiment, the pick-up roller 320 and the resisting roller 420 are preferably finger-shaped rollers, so as to generate sufficient force when contacting the film 20, thereby ensuring that the film 20 can be smoothly fed into the magazine 31. In order to further secure the effect of use, the number of the pick roller 320 and the knock roller 420 is preferably two or more. The driving power source 200 is preferably a servo motor, and the output end of the servo motor drives the first rotating shaft 311 to rotate, so as to drive the pick-up roller 320 to rotate simultaneously, and to flap the first portion 21, so as to shift the film 20 from the magazine 31 by friction. The urging roller 420 is also rotated in the opposite direction by the driven gear 410 to flap the second portion 22 of the film 20 to generate a backward or upward feeding force F. The mechanism has simple design, is ingenious and practical, needs fewer parts and has low manufacturing cost.

Further, referring to fig. 1 and fig. 2, in an embodiment, the sheet feeding device 10 further includes a transmission mechanism 500, and the driving gear 310 is linked with the driven gear 410 through the transmission mechanism 500. The transmission mechanism 500 includes a first synchronous pulley 510, a second synchronous pulley 530, a third synchronous pulley 540, a first synchronous belt 520 and a second synchronous belt 550, an output end of the driving power source 200 is connected with the first synchronous pulley 510, the first synchronous pulley 510 is in transmission connection with the driving gear 310 through the first synchronous belt 520, the second synchronous pulley 530 is installed on the first rotating shaft 311, the third synchronous pulley 540 is arranged on the cassette compartment 100 and is in mesh transmission with the driven gear 410, and the second synchronous pulley 530 is in transmission connection with the third synchronous pulley 540 through the second synchronous belt 550. Specifically, through the multi-stage transmission arrangement of the transmission mechanism 500, the picking roller 320 and the abutting roller 420 are driven to rotate in opposite directions simultaneously by only one servo motor, so as to achieve different functions, and the multi-stage transmission mechanism is simple in structure and low in manufacturing cost.

Further, with reference to fig. 3, in an embodiment, the film storage 31 has a bin inlet 32, the bottom of the film cassette compartment 100 is provided with an output opening 110 for outputting the film 20 corresponding to the bin inlet 32, the pick-up roller 320 is disposed at the bottom of the film cassette compartment 100 and is close to the output opening 110, and the inner side of the bottom of the film cassette compartment 100 is gradually inclined downward from the end far away from the output opening 110 toward the output opening 110. With the arrangement, the film 20 can slide to the picking roller 320 along the inclined angle of the inner side of the bottom of the film cassette bin 100, so that the film 20 can be continuously output, and the film cassette bin is simple in structure and easy to realize.

Further, with continued reference to fig. 1 and fig. 2, in an embodiment, the sheet feeding device 10 further includes a first warehousing sensor 600, and the first warehousing sensor 600 is configured to detect a warehousing status of the sheet storage 31. The sheet feeding apparatus 10 further includes a second stocker sensor 700, and the second stocker sensor 700 is used to detect the stocker status of the magazine stocker 100. Specifically, the controller 40 may monitor the warehousing status of the magazine 31 and the cassette magazine 100 in real time according to the first and

second warehousing sensors

600 and 700. If the magazine 31 is empty, the controller 40 controls the driving power source 200 to start operating to automatically replenish the printer 30 with the film 20. If the magazine 100 is empty, the controller 40 controls the driving power source 200 to stop working, or may alert the user by an alarm or the like.

Referring to fig. 2 and 3, in an embodiment, the sheet feeding device 10 further includes a mounting rack 800, the mounting rack 800 includes a chassis and a support connected to the chassis, the printer 30 is disposed on the chassis, and the sheet cassette compartment 100 is fixedly mounted on the support. The printer 30 presses on the chassis by its own weight, so that the cassette magazine 100 mounted on the support is positioned at one side of the printer 30, ensuring the normal use of the cassette magazine 100.

An embodiment of a specific operation mode of the sheet feeding device 10 is as follows:

when the first storage sensor 600 detects that the inside of the film storage compartment 31 in the printer 30 is empty, the servo motor starts to work, the driving gear 310 is driven to rotate by the first synchronous pulley 510 and the first synchronous belt 520, the pickup roller 320 is driven to rotate in the forward direction by the first rotating shaft 311, and then the driven gear 410 is driven to rotate by the second synchronous pulley 530, the third synchronous pulley 540 and the second synchronous belt 550, and the ejection roller 420 is driven to rotate in the reverse direction.

The pick-up roller 320 rotates forward toward one side of the film storage 31 of the printer 30, the pick-up roller 320 is configured such that the pick-up teeth push the last film 20 printed in the film storage 31 forward, and simultaneously pull a portion of the film 20 in the film cartridge 100 forward toward the printer 30, so that the film 20 is pulled above the film storage 31 and falls down into the film storage 31 by the gravity of the film 20 for the next printing, and the pick-up teeth push the last film 20 printed in the printer 30 forward, so that the film 20 pulled from the film cartridge 100 does not fall to the front end of the last film 20 printed, and normal printing of the printer is not affected.

In addition, the abutting roller 420 is rotated reversely and disposed in the cartridge magazine 100 to abut against the front end of the film 20, so that the film 20 can be inclined to the rear side. The function of the device is that, because the bottom of the magazine 100 is an inclined plane, the film 20 in the magazine 100 is in a state of high-low fall, when the resisting roller 420 rotates reversely, the film 20 at the front end in the magazine 100 can be pulled downwards, and the height of the film 20 at the back in the magazine 100 is higher than that of the resisting roller 420, so that the teeth on the resisting roller 420 simultaneously pull the film 20 at the back in the magazine 100 backwards, so as to prevent the film 20 at the back in the magazine 100 from generating pressure on the film 20 at the front, thereby affecting the film 20 at the front to fall into the magazine 31 of the printer 30.

When a portion of the film 20 in the magazine 100 enters the magazine 31, the first storage sensor 600 detects that there is sufficient film 20 in the magazine 31, the controller 40 controls the servo motor to stop working, the pick-up roller 320 and the lower resisting roller 420 stop rotating at the same time, and at this time, the teeth on the pick-up roller 320 protrude out of the bottom surface of the magazine 100 and are stationary, so as to block the remaining film 20 in the magazine 100 to prevent it from falling down.

The invention also provides a medical film printer device 50, the medical film printer device 50 comprises a controller 40, a printer 30 and a film feeding device 10 installed in a film storage bin 31 of the printer 30, the specific structure of the film feeding device 10 refers to the above embodiments, and as the film feeding device 10 adopts all technical solutions of all the above embodiments, the medical film printer device at least has all beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein. The controller 40 is connected to the printer 30 and the driving power source 200 of the sheet feeding device 10.

The film feeding device 10 and the medical film printer device 50 provided by the invention have the following beneficial effects:

in the film feeding device 10, after the first stocker sensor 600 detects that the film 20 in the magazine 31 of the printer 30 has been printed, the driving power source 200 drives the pickup roller 320 of the pickup mechanism 300 to rotate and contact the first portion 21 of the film 20, thereby feeding the film 20 in the magazine 100 into the magazine 100. When the transport is completed, the pick roller 320 stops rotating and may also act as a stop for the film 20 in the cartridge magazine 100. Meanwhile, the driving mechanism 500 is linked to drive the supporting roller 420 of the supporting mechanism 400 to rotate reversely and support against the second portion 22 of the film 20, so that the film 20 in the magazine 100 exerts a paper feeding supporting force F, which facilitates the film 20 to smoothly enter the magazine 100. By the design, the novel portable solar water heater is reasonable in overall structure design, simple and portable, good in using effect, simple to operate, low in manufacturing cost and suitable for popularization and application.
