Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The embodiment of the utility model provides a conveyor 10 is used for carrying the formation of image medium. Of course, in other embodiments of the present invention, the conveying device 10 can also be used for conveying other products, and is not limited herein. Specifically, the media is paper media or photosensitive photothermographic film media. In this embodiment, the imaged media is an imaged film.

Referring to fig. 1 to 9, a conveying device 10 according to the present invention will now be described. A delivery device 10 includes a housing 100, a first channel 110 received within the housing 100. A transmission 200 is also included. The first end 111 of the first channel 110 is disposed opposite the imaged media exit at the rear end of the printer. First end 111 is for receiving imaged media at an imaged media outlet. The second end 112 of the first channel 110 is located above the front end of the printer. The actuator 200 is used to transport the imaged media from the first end 111 along the first path 110 to the second end 112 and out the second end 112. The moving trajectory of the imaged medium is shown as a in fig. 5. The imaged medium at the rear end of the printer is conveyed from the first end 111 to the second end 112 along the first channel 110 by the transmission device 200 and is guided out from the second end 112, so that the imaged medium is prevented from being wound around the rear end of the printer or bent over to be wound around the upper part of the printer to be taken out. The housing 100 includes two side plates 120 disposed opposite to each other and a cavity case 130 between the two side plates 120. The chamber case 130 is fixed to the side plate 120 by bolts. The chamber housing 130 encloses the first passage 110.

Referring to fig. 1 to 4, a first sensor 300 for detecting the passing of the imaged medium is disposed in front of the first end 111 to turn on the driving device 200. A second sensor 400 for detecting the passage of the imaged media is provided behind the second end 112 to turn off the transmission 200 after a preset delay time. The imaged media is directed out of the imaged media outlet and detected by the first sensor 300, which controls the first sensor 300 to control the actuator 200 to open to transport the imaged media from the first end 111 along the first path 110 to the second end 112 and out of the second end 112. The imaged media is detected by the second sensor 400 before being directed out of the second end 112. The second sensor 400 controls the transmission 200 to be turned off after a preset delay time. The preset delay time takes into account the speed at which the actuator 200 conveys the imaged media and the size of the imaged media. In this embodiment, the preset delay time is 10S.

Referring to fig. 1 to 6, the first end 111 has a guiding opening 500. The guide port 500 is used to guide the third end of the imaged media into the first end 111. Specifically, the guide opening 500 includes an upper guide plate 510 and a lower guide plate 520 disposed at an acute angle. The small open end of the guide port 500 communicates with the first end 111. The upper guide plate 510 is a flat plate. The lower guide 520 is a flap. The lower guide plate 520 includes a first leg 521 connected to the first end 111 and a second guide plate 522 for forming a larger angle with the upper guide plate 510. In this embodiment, the first plate 521 is disposed horizontally, it being understood that in other embodiments, the first plate 521 may be disposed obliquely to facilitate guiding the imaged medium toward the first end 111. Further, the distance between the first end 111 and the imaged medium outlet should be as close as possible so that the imaged medium exiting from the imaged medium outlet has a certain inertia, and the third end can be guided into the first end 111 along the first fulcrum plate 521. Or the imaged medium led out from the imaged medium outlet is still elastic when the imaged medium is led into the first end 111 at the third end, so that the transmission device 200 can smoothly lead the imaged medium into the first channel 110. In this embodiment, the first sensor 300 and the second sensor 400 are both plastic bow-type photosensors. The first sensor 300 is disposed on the first plate 521 with its probe passing through the guide opening 500. A second sensor 400 is disposed on the cavity housing 130 with its probe passing through the first passage 110.

Further, the transmission 200 includes a driving mechanism 210, a first transmission mechanism 220 at the first end 111, and a plurality of second transmission mechanisms 230 sequentially disposed along the first passage 110. The first transmission mechanism 220 includes a first driving shaft 221 and a first driven shaft 222. A first roller 2211 is fixed to the first driving shaft 221. The first driven shaft 222 is provided with a second roller 2221. The second transmission mechanism 230 includes a second driving shaft 231 and a second driven shaft 232. A third roller 2311 is fixed to the second driving shaft 231. The second driven shaft 232 is provided with a fourth roller 2321. The first and

second driving shafts

221 and 231 are provided at both ends with first flange bearings 2212. The side plate 120 is provided with a first through hole matching with the first flange bearing 2212 and further limits the axial play of the first driving shaft 221 and the second driving shaft 231 by a snap spring phi 7. The first driven shaft 222 and the second driven shaft 232 are each provided with a second flange bearing 2222 at both ends. The side plate 120 is provided with a second through hole which is in clearance fit with the second flanged bearing 2222 and further limits the axial play of the first driven shaft 222 and the second driven shaft 232 by a snap spring phi 7. In this embodiment, the first flange bearing 2212 and the second flange bearing 2222 are each model MF148 ZZ.

Further, the working surfaces of the first and

second rollers

2211 and 2221 are attached to form a first attachment surface. The first abutment surface has a first side 113 remote from the first passage 110. The third end can be inserted in the first side 113. The working surfaces of the third roller 2311 and the fourth roller 2321 are abutted to form a second abutting surface. The first, second, third, and

fourth rollers

2211, 2221, 2311, and 2321 are EPDM sheaves. The EPDM is a rubber material, and thus the first contact surface is formed by elastically contacting the first roller 2211 and the second roller 2221. Similarly, the second contact surface is formed by elastically contacting the third roller 2311 and the fourth roller 2321. The first and second mating surfaces have a degree of "tackiness" to the imaged media to facilitate passage of the imaged media past the first/second mating surfaces. And the elastic fit can accommodate different thicknesses of imaged media, making the conveyor 10 more versatile in application.

Further, the first roller 2211, the second roller 2221, the third roller 2311 and the fourth roller 2321 are all partially received in the first channel 110. The cavity housing 130 is provided with a corresponding third through hole. The driving mechanism 210 is used to drive the first and

second driving shafts

221 and 231 to rotate. Due to the existence of the first contact surface and the second contact surface, when the first driving shaft 221 and the second driving shaft 231 rotate, the corresponding first driven shaft 222 and the second driven shaft 232 also rotate, and thus the imaged medium is conveyed.

Further, a first adjusting spring is provided between the first driving shaft 221 and the first driven shaft 222. The first adjusting spring is used to adjust the attaching force between the first roller 2211 and the second roller 2221. A second adjusting spring 233 is provided between the second driving shaft 231 and the second driven shaft 232. The second adjustment spring 233 is used to adjust the attaching force between the third roller 2311 and the fourth roller 2321. Through setting up first regulating spring and second regulating spring 233 for the medium of having formed images that gets into between first binding face/the second binding face is laminated the centre gripping all the time, can adapt to the medium of having formed images of different thickness, avoids causing contact failure, the problem of skidding because of the medium of having formed images is too thin. In this embodiment, the first flange bearing 2212 is matched with the first through hole, that is, the first flange bearing 2212 and the first through hole do not move radially; and the second flange bearing 2222 and the second through hole are clearance-matched, i.e., a radial adjustment space is reserved, so as to adapt to imaged media with different thicknesses. In the present embodiment, the first adjustment spring is bridged on the first driven shaft 222. First annular grooves are formed at two ends of the first driven shaft 222. The first annular groove is provided integrally with or separately from the first driven shaft 222. The first adjusting spring is overlapped in the first annular groove.
