Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a paper box that can automatically feed paper. Background Technology

[0002] With the continuous advancement of technology, the technology of self-service printers is also constantly being upgraded. As printers become more widely used, their specifications are constantly improving, with the paper trays being able to hold more and more paper. However, the more paper there is, the more complex the paper tray design becomes, leading to problems such as paper feeding failures and paper jams. Therefore, a convenient paper feeding device is needed to automatically feed paper into the paper tray after the original paper tray has run out, thus allowing printing to continue and ensuring the normal operation of the printer.

[0003] Chinese utility model patent with publication number CN108217282A discloses a printer layered paper feeding mechanism and its working method. The layered design separates the paper during printing, reducing the error rate. However, the device lacks design in terms of paper capacity and paper supply. Therefore, this utility model provides a paper tray that can automatically feed paper. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a paper box that can automatically feed paper, thus overcoming the problems in existing technologies.

[0005] The technical solution adopted by this utility model is as follows: a paper box capable of automatic paper feeding, including a paper dispensing mechanism and a paper supply mechanism connected to the paper dispensing mechanism. The paper supply mechanism includes a spare box body and a sliding plate slidably mounted on the spare box body. The paper dispensing mechanism includes a separation component and a main box body mounted on the spare box body, with a paper dispensing port installed on the main box body. A placement plate is slidably mounted on the sliding plate and fixedly connected to a pull door. Under normal conditions, a paper tray is inserted into the placement plate. The sliding plate is slidably connected to a toothed U-shaped plate, which is connected to the sliding plate via a long spring. The toothed U-shaped plate has toothed structures on both sides, each toothed structure engaging with a lifting gear. The lifting gears are coaxially and fixedly connected to a transport screw, and the threaded section on the transport screw engages with the threaded section of the lifting plate. The push plate is slidably mounted on the spare box body. The push plate is slidably engaged with the slide rod. A short spring is sleeved on the slide rod. The toothed U-shaped plate is threadedly engaged with the threaded section of the one-way lead screw. The one-way lead screw is connected to the two-way lead screw through a belt. The two-way lead screw is threadedly engaged with the upper push plate. The upper push plate is slidably mounted on the spare box body. The upper push plate corresponds to the position of the separation component. The main box body is fixedly mounted with a vertical rod and a vertical plate. A lower clamping plate is slidably mounted on the vertical rod. A middle plate is slidably mounted on the lower clamping plate. A clamping spring is installed on the middle plate. The middle plate is located between the lower clamping plate and the separation component. An upper clamping plate is slidably mounted on the vertical rod. A separation component is installed on the upper clamping plate. The separation component is used to push the paper on the middle plate one sheet at a time towards the paper dispensing port. The upper clamping plate and the lower clamping plate move relative to or away from each other.

[0006] Furthermore, an upper rack is provided on the upper clamping plate, and a lower rack is provided on the lower clamping plate. Both the upper and lower racks mesh with the drive gear, which is mounted on the main housing and rotates along the axial direction.

[0007] Furthermore, the first end of the clamping spring is connected to the intermediate plate, and the second end of the clamping spring is connected to the lower clamping plate.

[0008] Furthermore, the separation assembly includes a separation roller rotatably mounted on an upper clamping plate, and multiple movable blades rotatably mounted on the separation roller. The movable blades are evenly distributed on the separation roller, and each movable blade is connected to the separation roller through multiple separation springs.

[0009] Furthermore, multiple plastic sheets are installed on the movable blades.

[0010] Furthermore, the separation component corresponds to the position of the pressure roller, and there are two pairs of pressure rollers, with the two pairs of pressure rollers rotating in opposite directions.

[0011] Furthermore, each pressure roller is coaxially and fixedly connected to a second pressure feeding gear, and the second pressure feeding gear on each pair of pressure rollers meshes with a first pressure feeding gear. The two first pressure feeding gears mesh with each other, and one of the first pressure feeding gears is coaxially and fixedly connected to a second bevel gear. The second bevel gear meshes with the first bevel gear, and the first bevel gear is coaxially and fixedly connected to a transmission gear.

[0012] Furthermore, transmission gear one and transmission gear two mesh with each other, and transmission gear two is connected to a double-acting lead screw via belt two.

[0013] The advantages of this utility model compared with the prior art are: (1) This utility model moves the lifting plate towards the direction of the upper pushing plate, and the two lifting plates move up to contact the paperboard on the placement plate, pushing the paperboard to rise and separate from the placement plate. When the toothed structure on the toothed U-shaped plate disengages from the lifting gear, the lifting plate moves the paperboard to the position corresponding to the upper pushing plate and stops moving; (2) This utility model drives the double-direction screw to rotate through the belt, and the double-direction screw rotates to drive the upper pushing plate to reciprocate on the spare box. When the lifting plate moves to the position corresponding to the upper pushing plate, the paperboard moves up to the position corresponding to the upper pushing plate and stops moving. When the upper push plate is in the position corresponding to the upper push plate, the upper push plate moves in the direction of the pressure roller. The upper push plate pushes the paper on the cardboard between the two pairs of pressure rollers. (3) This utility model drives the three-drive active gear of the starting motor to rotate, which drives the upper rack and the lower rack to move relative to each other. The upper rack drives the upper clamping plate and the separation component to move down, and the lower rack drives the lower clamping plate to move up. The lower clamping plate and the separation component press the paper on the middle plate. During this process, the clamping spring is compressed. As the paper is consumed and the thickness decreases, the middle plate will rise under the elastic force of the clamping spring to maintain the clamping force on the paper.

[0028] There are two lifting plates 107, two transport screws 108, and two lifting gears 109; two pairs of short springs 110 and sliding rods 111.

[0029] An upper rack 207 is provided on the upper clamping plate 206, and a lower rack 209 is provided on the lower clamping plate 212. Both the upper rack 207 and the lower rack 209 mesh with the drive gear 208. The drive gear 208 is rotatably mounted on the main housing 202 along the axial direction. The drive gear 208 is connected to the output shaft of the motor 224. The motor 224 is mounted on the main housing 202.

[0030] The first end of the clamping spring 211 is connected to the intermediate plate 213, and the second end of the clamping spring 211 is connected to the lower clamping plate 212.

[0031] The separation assembly includes a separation roller 217, movable blades 218, plastic sheet 219, separation spring 220, separation gear one 221, separation gear two 222, and motor two 223. The separation roller 217 is rotatably mounted on the upper clamping plate 206. Multiple movable blades 218 are rotatably mounted on the separation roller 217. The movable blades 218 are evenly distributed on the separation roller 217. Each movable blade 218 is connected to the separation roller 217 through multiple separation springs 220.

[0032] There are two separating rollers 217. Each separating roller 217 is coaxially fixedly connected to a separating gear 221. Both separating gears 221 mesh with separating gear 222. Separating gear 222 is connected to the output shaft of motor 223. Motor 223 is mounted on the upper clamping plate 206.

[0033] Multiple plastic sheets 219 are provided on the movable blade 218.

[0034] The separation component corresponds to the pressure roller 203. There are two pairs of pressure rollers 203, and the two pairs of pressure rollers 203 rotate in opposite directions.

[0035] Each pressure roller 203 is coaxially and fixedly connected to a second pressure gear 205. The second pressure gear 205 on each pair of pressure rollers 203 meshes with a first pressure gear 204. The first pressure gear 204 and the second pressure gear 205 are rotatably mounted on the main box 202. The two first pressure gears 204 mesh with each other. One of the first pressure gears 204 is coaxially and fixedly connected to a second bevel gear 216. The second bevel gear 216 meshes with a first bevel gear 215. The first bevel gear 215 is coaxially and fixedly connected to a first transmission gear 118. The first transmission gear 118 is rotatably mounted on the spare box 102.

[0036] The first transmission gear 118 and the second transmission gear 119 mesh with each other. The second transmission gear 119 is rotatably mounted on the spare box 102. The second transmission gear 119 is connected to the double-acting lead screw 114 through the second belt 115.

[0037] The working principle of this utility model is as follows: Open the sliding door 101, pull the placement plate 104 to slide on the sliding plate 105, pull out the placement plate 104 and the placement cardboard 121 on the placement plate 104 to the spare box 102, place a stack of papers 3 on the placement cardboard 121 and push it back.

[0038] When the paper output mechanism 2 needs to replenish paper 3, the motor 112 is started to drive the one-way lead screw 106 to rotate, causing the toothed U-shaped plate 116 to slide on the sliding plate 105, compressing the long spring 117. When the long spring 117 is compressed to a certain extent, the toothed U-shaped plate 116 pushes the long spring 117 and the sliding plate 105 together to move towards the motor 112, causing the placement plate 104, the paperboard 121, and the paper 3 to move; the toothed U-shaped plate 116 moves towards the motor 112. When moving in direction 2, the toothed structure on the toothed U-shaped plate 116 contacts the lifting gear 109, causing the lifting gear 109 to rotate, which in turn causes the transport screw 108 to rotate, causing the lifting plate 107 to slide on the spare box 102. At this time, the lifting plate 107 slides on the slide rod 111, compressing the short spring 110, until the sliding plate 105 slides above the lifting plate 107. Then, the motor 112 reverses, causing the one-way screw 106 to reverse, and the toothed U-shaped plate... 116 moves toward the sliding door 101. At this time, since the long spring 117 is in a compressed state, during the process of the toothed U-shaped plate 116 moving a preset distance toward the sliding door 101, the sliding plate 105 is still above the push plate 107. During this process, the toothed structure on the toothed U-shaped plate 116 drives the lifting gear 109 to reverse when it moves, which drives the transport screw 108 to reverse. The push plate 107 maintains contact with the threaded section on the transport screw 108 under the elastic force of the short spring 110. The transport screw 108 reverses and drives the push plate 107 to move toward the upward push plate 120. The two push plates 107 move upward and contact the placement plate 121 on the placement plate 104, pushing the placement plate 121 to rise and separate from the placement plate 104. When the toothed structure on the toothed U-shaped plate 116 disengages from the lifting gear 109, the push plate 107 drives the placement plate 121 to move to the position corresponding to the upward push plate 120 and no longer moves.

[0039] The rotation of the unidirectional lead screw 106 drives the rotation of the bidirectional lead screw 114 via the belt 113. The rotation of the bidirectional lead screw 114 drives the upper push plate 120 to reciprocate on the spare box 102. When the push plate 107 moves to the position corresponding to the upper push plate 120, the upper push plate 120 moves towards the pressure roller 203. The upper push plate 120 pushes the paper 3 on the cardboard 121 between the two pairs of pressure rollers 203. The rotating bidirectional lead screw 114 drives the transmission gear 119 to rotate via the belt 115, which in turn drives the transmission gear 118 to rotate, the bevel gear 215 to rotate, the bevel gear 216 to rotate, the pressure feeding gear 204 to rotate, and the two pairs of pressure feeding gears 205 and the pressure rollers 203 to rotate. The two pairs of rotating pressure rollers 203 transport the paper 3 towards the separation roller 217 until the paper 3 is transported onto the intermediate plate 213.

[0040] The starter motor 224 drives the drive gear 208 to rotate, causing the upper rack 207 and the lower rack 209 to move relative to each other. The upper rack 207 drives the upper clamping plate 206 and the separation component to move downward, while the lower rack 209 drives the lower clamping plate 212 to move upward. The lower clamping plate 212 and the separation component press the paper 3 tightly onto the intermediate plate 213. During this process, the clamping spring 211 is compressed. As the thickness of the paper 3 decreases due to wear, the intermediate plate 213 will rise under the elastic force of the clamping spring 211, maintaining the clamping force on the paper 3.

[0041] The start motor 223 drives the separation gear 222 to rotate, which in turn drives the separation gear 221 and the separation roller 217 to rotate. When the separation roller 217 rotates, the movable blade 218 on the separation roller 217 contacts the paper 3 closest to the separation roller 217. The movable blade 218 swings, and the compression separation spring 220 on the movable blade 218 adsorbs the paper 3 through the plastic sheet 219 and drives the paper 3 forward to perform the separation operation. The separated single sheet of paper 3 is pushed to the paper pick-up port 201 by the movable blade 218.

Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
