Detailed Implementation
[0027] refer to Figures 1 to 10 The printer paper tray structure shown includes a paper placement component 1 for placing printing paper. The paper placement component 1 adjusts the position of the printing paper and keeps the printing paper in contact with the paper feed rollers. The paper placement component 1 is equipped with a paper separating component 2 to ensure that the printing paper is fed one sheet at a time. At the same time, the paper separating component 2 automatically collects damaged printing paper. The paper placement component 1 is also equipped with a detection component 3 to detect the printing paper. The detection component 3 prevents the printing paper from piling up too much or having uneven thickness, which would affect the printing effect.
[0028] The placement component 1 includes a base 101. Two sets of adjustment brackets 102 are slidably mounted on the side of the base 101. When the adjustment brackets 102 slide on the base 101, they push the two sides of the printing paper to ensure that the printing paper is in the middle position of the base 101. A second adjustment bracket 103 is slidably mounted on the base 101. When the second adjustment bracket 103 moves on the base 101, it pushes the printing paper to move on the base 101, ensuring that the printing paper is on the top plate 104 and in contact with the paper feed rollers. The top plate 104 is rotatably mounted on the base 101. A torsion spring is provided between the top plate 104 and the base 101. An adsorption plate 108 is provided at the lower end of the base 101, and an adsorption plate 108 is provided at the lower end of the top plate 104. An electromagnet block 107 is provided. When the electromagnet block 107 is activated, it attracts the adsorption plate 108, causing the top plate 104 to rotate on the base 101. When the electromagnet block 107 is deactivated, the top plate 104, through a torsion spring, causes the printing paper to adhere to the paper feed roller. A waste paper bin 106 is provided at one end of the base 101 to store waste and broken printing paper. A set of movable boxes 109 are slidably installed inside both sides of the base 101. An adsorption head 110 is slidably installed inside the movable box 109 to adsorb debris such as paper scraps and dust inside the base 101. Two sets of air separators 105 are also provided on the side of the base 101. During paper feeding, the air separators 105... 5. Blow air onto the printing paper to spread it out, improving single-sheet feeding efficiency. Place the printing paper on the base 101, then drive the adjustment frame 2 103 and adjustment frame 102 to adjust the position of the printing paper, so that the printing paper is in the middle of the base 101. At the same time, push the printing paper onto the top plate 104. In the initial state, the electromagnet block 107 is attracted to the suction plate 108, and the torsion spring on the top plate 104 is under force. When using the base 101, place the base 101 into the printer. At this time, turn off the electromagnet block 107, releasing the fixation between the electromagnet block 107 and the suction plate 108. The torsion spring on the top plate 104 drives the top plate 104 to rotate on the base 101, and the top plate 104 moves the printing paper. When the paper feed rollers are in contact with the paper feed rollers, the air separator 105 is driven to blow multiple sets of printing paper when paper needs to be fed. When the base 101 is removed from the printer, the electromagnet 107 is driven to attract the adsorption plate 108. The electromagnet 107 drives the top plate 104 to move and is in contact with the adsorption plate 108. When it is necessary to clean the inside of the base 101, the moving box 109 is driven to slide inside the base 101, and the adsorption head 110 is driven to adsorb the debris inside the base 101. The adsorption head 110 is driven to slide on the moving box 109 to increase the adsorption range of the adsorption head 110 and ensure the cleaning efficiency of the adsorption head 110.
[0029] The paper separating assembly 2 includes a paper separating bracket 201 mounted on the side of the base 101. A fixing bolt 205 is provided on the paper separating bracket 201, which is fixed to the base 101 by the fixing bolt 205. A separating plate 204 is detachably mounted on the paper separating bracket 201. The separating plate 204 is an injection-molded part that adheres to the printing paper. Pressure is applied to the printing paper during adhesion to ensure single-sheet feeding. The adhesion pressure is provided by the elastic deformation of the plastic of the separating plate 204. Two sets of movable frames 202 are slidably mounted on the paper separating bracket 201, and two sets of lifting frames 206 are slidably mounted on the movable frames 202. Both sets of lifting frames 206 are equipped with rotatable paper separating rollers 203. The paper separating rollers 203 are in contact with the printing paper, and the paper separating rollers 203 transport the printing paper as they rotate. A baffle 208 is slidably mounted on the paper separating bracket 201, and the baffle 208 blocks the printing paper. When the paper is fed, the paper feeding roller is driven to move, and the top plate 104 drives the printing paper to contact the paper feeding roller. At this time, the paper feeding roller drives the printing paper to move, and the printing paper contacts the separating plate 204. The separating plate 204 applies pressure and friction to the printing paper, leaving the excess printing paper behind. At the same time, the baffle 208 is driven to move and extend, and the baffle 208 blocks the excess printing paper. To prevent insufficient friction from preventing the paper from being stuck, the baffle 208 blocks the paper, driving the paper separating roller 203 to rotate. The paper separating roller 203 carries the paper back to the top plate 104, driving the lifting frame 1 206 to slide on the moving frame 202, thus processing paper of different thicknesses. The paper separating bracket 201 is slidably equipped with a pusher plate 211 and a lifting frame 209. The lifting frame 209 is equipped with multiple suction heads 210, which suction the paper. The paper separating bracket 201 is equipped with a detection camera, which detects the paper. When damaged or broken paper is found, the camera will detect it. The lifting frame 209 moves, and the lifting frame 209 moves the suction head 210 to the top of the paper separating bracket 201. The suction head 210 then suctions the printing paper. After the paper separating bracket 201 has finished suctioning the printing paper, the lifting frame 209 is reset. The lifting frame 209 moves the printing paper and drives the pusher plate 211 to move on the paper separating bracket 201. The pusher plate 211 pushes the printing paper between the two sets of recycling wheels 207, and drives the two sets of recycling wheels 207 to rotate. When the two sets of recycling wheels 207 rotate, they roll the printing paper into the waste paper bin 106, completing the processing of waste printing paper.
[0030] The detection component 3 includes two sets of detection frames 301 slidably mounted on the base 101. Each set of detection frames 301 has a slidably mounted lifting plate 305, and a support head 306 slidably mounted on the lifting plate 305. A second spring 307 is disposed between the lifting plate 305 and the support head 306. A third lifting frame 303 is slidably mounted on the base 101, and a support plate 302 is slidably mounted on the third lifting frame 303. A first spring 304 is disposed between the support plate 302 and the third lifting frame 303. Pressure sensors are disposed on both the first spring 304 and the support head 306. When printing paper is placed on the base 101, the third lifting frame 303 is driven to slide on the base 101, causing the first spring 304 to move. When the third lifting frame 303 is flush with the base 101, the driving of the third lifting frame 303 stops. 03. At this point, the printing paper is placed on the support plate 302. The printing paper applies pressure to the support plate 302, and the support plate 302 is pressed onto the lifting frame 303 and slides. The spring 304 is compressed. The pressure sensor on the support plate 302 detects the weight of the printing paper to avoid overloading. After the detection is completed, the lifting frame 303 is driven to reset. At this time, the support plate 302 is reset by the deformation restoring force of the spring 304, and the two sets of detection frames 301 are driven to slide on the base 101. The detection frame 301 drives the support head 306 to be located at the top of the printing paper, and drives the lifting plate 305 to slide on the detection frame 301. The lifting plate 305 drives the support head 306 to fit with the printing paper. The printing paper presses against the support head 306, and the support head 306 detects the thickness of the printing paper according to the pressure detector value.
[0031] Working principle: In the initial state, the electromagnet block 107 is attracted and fixed to the adsorption plate 108. The printing paper is placed on the base 101. Then, the adjustment frame 2 103 and adjustment frame 102 are driven to adjust the position of the printing paper, so that the printing paper is in the middle of the base 101. At the same time, the printing paper is pushed onto the top plate 104, and the lifting frame 303 is driven to slide on the base 101. The lifting frame 303 drives the spring 104 to move. When the lifting frame 303 is aligned with the base 101, the driving of the lifting frame 303 is stopped. At this time, the printing paper is placed on the support plate 302. The printing paper applies pressure to the support plate 302, and the support plate 302 is pressed onto the lifting frame 303 and slides. The spring 104 is compressed. The pressure sensor on the support plate 302 detects the weight of the printing paper to prevent it from being placed in the wrong position. If there are too many, after the detection is completed, drive the lifting frame 303 to reset. At this time, the support plate 302 is reset by the deformation restoring force of the spring 304, and drive the two sets of detection frames 301 to slide on the base 101. The detection frame 301 drives the support head 306 to be located at the top of the printing paper, and drives the lifting plate 305 to slide on the detection frame 301. The lifting plate 305 drives the support head 306 to stick to the printing paper. The printing paper presses the support head 306. The support head 306 detects the thickness of the printing paper according to the pressure detector value. Then, place the base 101 in the printer, turn off the electromagnet block 107, and release the fixation between the electromagnet block 107 and the adsorption plate 108. At this time, the top plate 104 rotates through the internal torsion spring. The top plate 104 drives the printing paper to stick to the paper feed roller, completing the paper detection and position adjustment.
[0032] When paper is fed, the paper feed roller is driven to move, and the top plate 104 causes the printing paper to come into contact with the paper feed roller. At this time, the paper feed roller drives the printing paper to move, and drives the air separator head 105 to blow multiple sets of printing paper. The printing paper comes into contact with the separating plate 204, and the separating plate 204 applies pressure and friction to the printing paper to leave the excess printing paper. At the same time, the baffle 208 is driven to move and extend, blocking the excess printing paper to prevent insufficient friction from preventing the printing paper from being left. After the baffle 208 blocks the printing paper, the paper separating roller 203 is driven to rotate, and the paper separating roller 203 drives the printing paper back to the top plate 104. The lifting frame 206 is driven to slide on the moving frame 202 to process printing paper of different thicknesses.
[0033] When damaged or broken printing paper appears, the second lifting frame 209 is moved, which in turn moves the second suction head 210 to the top of the paper separating bracket 201. Multiple sets of suction heads 210 are then driven to absorb the printing paper. After the paper separating bracket 201 has finished absorbing the printing paper, the second lifting frame 209 is reset. The second lifting frame 209 then moves the printing paper and drives the pusher plate 211 to move on the paper separating bracket 201. The pusher plate 211 pushes the printing paper between the two sets of recycling wheels 207, which then rotate. As the two sets of recycling wheels 207 rotate, they roll the printing paper into the waste paper bin 106, completing the processing of the waste printing paper.
[0034] When cleaning the inside of the base 101, the drive moving box 109 slides inside the base 101, driving the adsorption head 110. The adsorption head 110 adsorbs the debris inside the base 101. The drive adsorption head 110 slides on the moving box 109 to increase the adsorption range of the adsorption head 110 and ensure the cleaning efficiency of the adsorption head 110.
[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
