Description

Technical Field

[0001] This utility model relates to the field of photocopier technology, specifically to a paper separation device for photocopiers. Background Technology

[0002] Copiers operate on an analog basis and can only accurately copy documents. Their functions generally include copying, printing, scanning, and network connectivity. The copier's paper feed system separates the paper entering the copier to prevent multiple sheets from entering the copier at the same time and causing a paper jam.

[0003] However, the paper separators used in existing copiers can only separate one sheet of paper at a time. In high humidity conditions, multiple sheets of paper can easily stick together. When feeding paper, the paper separator blocks the bottom sheet, and the multiple sheets above continue to enter the copier, which can easily cause paper jams and malfunctions.

[0004] As disclosed in Chinese Patent CN219771243U, a paper separation device for a copier feeds paper into the copier after the paper feed roller contacts the paper. The paper separation roller below rotates in the opposite direction to push the stuck paper back into the paper tray. If multiple sheets of paper enter, the paper separation roller at the rear can push the remaining paper into the paper tray. This avoids the problem that the paper separator used in existing copiers can only separate one sheet of paper at a time. In high humidity conditions, multiple sheets of paper are easily stuck together. When feeding paper, the paper separator blocks the bottom sheet, and the multiple sheets above continue to enter the copier, which can easily cause paper jams and malfunctions.

[0005] However, when using paper feed rollers to transport paper in existing technologies, it is necessary to ensure that a certain pressure is maintained between the paper and the paper feed rollers, so as to provide a certain friction between the paper feed rollers and the paper and ensure the paper separation effect.

[0006] Therefore, we urgently need to provide a paper separation device for photocopiers. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0027] When using paper feed rollers to transport paper in existing technologies, it is necessary to maintain a certain pressure between the paper and the paper feed rollers to provide sufficient friction and ensure effective paper separation. Please refer to [reference needed]. Figures 1-5 The embodiment provides a paper separation device for a copier, which can effectively improve the maintenance of friction between the paper and the paper feeding structure during the paper separation process. The paper separation device for a copier includes a paper tray 1, a paper feeding device is installed at the left end inside the paper tray 1, an auxiliary device is connected to the right side of the paper feeding device, and an adsorption device is connected to the bottom of the auxiliary device.

[0028] The paper feeding device includes a paper feeding structure and a stress structure, with the paper feeding structure installed in the center of the top surface of the stress structure. The stress structure includes a telescopic rod 101, with a spring 102 installed at the top of the telescopic rod 101. A paper bin 103 is connected to the top of the telescopic rod 101, and slide rods 105 are connected to the bottom of the paper bin 103 near its four corners. A slot 104 is connected to the bottom of the outer surface of the slide rod 105. The paper feeding structure includes a micro motor 106, with a rotating shaft 107 connected to the output end of the micro motor 106. A paper feeding roller 108 is installed on the outer surface of the rotating shaft 107, and a wheel sleeve 109 is installed on the outer surface of the paper feeding roller 108.

[0029] The bottom of the telescopic rod 101 and the slot 104 are fixedly connected to the bottom surface of the paper tray 1. The top of the spring 102 is fixedly connected to the bottom surface of the paper compartment 103. The outer surface of the slide rod 105 is slidably connected to the slot 104 in the middle of the slide groove. The micro motor 106 is detachably installed on the front of the paper tray 1. The two ends of the rotating shaft 107 are connected to the round holes on the front and back of the paper tray 1 through bearings.

[0030] By using the paper feeding device, the stress of the spring 102 causes the paper bin 103 to move accordingly as the weight of the paper inside decreases, thereby maintaining the friction between the paper and the paper feeding roller 108 and the roller sleeve 109.

[0031] When separating the paper inside the paper bin 103, the stress of the spring 102 causes the telescopic rod 101 to extend and retract. At the same time, the sliding of the slide rod 105 inside the slot 104 ensures the stability and balance of the lifting and lowering of the paper bin 103, so that the paper inside the paper bin 103 comes into contact with the wheel sleeve 109. The micro motor 106 is started to drive the rotating shaft 107 and the paper-feeding wheel 108 to rotate. When the paper-feeding wheel 108 drives the wheel sleeve 109 to rotate, the friction between the wheel sleeves 109 is used to achieve the paper-feeding separation effect. As the amount of paper decreases and the weight decreases, the stress of the spring 102 extends, ensuring that the friction between the paper and the wheel sleeve 109 is maintained. Example

[0032] Based on Implementation 1, the existing technology still has the problem that two sheets of paper can be fed simultaneously during the paper feeding process. Please refer to [link / reference needed]. Figures 1-5This embodiment provides a paper separation device for a copier, which can effectively solve the problem of two sheets of paper being fed simultaneously during the paper feeding process. The copier paper separation device includes an auxiliary device including a guide plate 201. A paper feed board 202 is connected to the right end of the guide plate 201. A slider 203 is fixedly installed on the front and back of the paper feed board 202. A guide rod 204 is connected to the outer surface of the slider 203. The left end of the guide plate 201 is hinged to the bottom right end of the paper tray 103, and the right end of the guide plate 201 is hinged to the left end of the paper feed board 202. The outer surface of the slider 203 is slidably connected to the guide rod 204 through a convex groove. The guide rod 204 is fixedly installed inside the top right end of the paper feed tray 1.

[0033] The adsorption device includes an adsorption box 301, a diversion pipe 302 connected to the middle of the bottom surface of the adsorption box 301, an air suction pipe 303 connected to the middle of the diversion pipe 302, and an air pump 304 connected to the bottom end of the air suction pipe 303. The top surface of the adsorption box 301 is connected to the bottom surface of the paper feed board 202, and the bottom of the air pump 304 is connected to the middle of the bottom surface of the paper feed box 1 near the right end.

[0034] By setting up auxiliary devices and adsorption devices, the friction layer on the top surface of the paper feeder 202 is used to facilitate the separation of excess paper, and the air pump 304 is used to pump air into the adsorption box 301 to prevent excessive paper feeding and paper jams.

[0035] During the paper feeding process, the guide plate 201 and the paper feeding board 202 guide the paper feeding. The guide plate 201, the paper feeding board 202, and the hinge between the guide plate 201 and the paper bin 103, along with the sliding of the slider 203 and the guide rod 204, adjust the position of the paper feeding board 202 accordingly. During the feeding process, the friction layer on the top surface of the paper feeding board 202 increases the friction of the excess paper at the bottom, preventing two sheets of paper from being fed simultaneously. At the same time, the air pump 304 is activated to adsorb the air inside the adsorption box 301 through the suction pipe 303 and the diversion pipe 302. The negative pressure inside the adsorption box 301 and the connection between the adsorption box 301 and the adsorption holes in the paper feeding board 202 adsorb the paper at the bottom, preventing paper jams caused by the simultaneous feeding of two sheets of paper.
