Description

Technical Field

[0001] This invention relates to the field of printer use, specifically to an efficient and uniform automatic paper dispenser and its usage method. Background Technology

[0002] Printers are tools used in daily life to transfer text information onto paper. Many businesses, when faced with a large volume of printing tasks, typically operate multiple printers simultaneously. Since the daily printing workload is the same, the amount of paper required by each printer is also the same. This necessitates manual sorting of the paper into specific portions before printing, feeding them to the respective printer's paper inlet, making the overall operation relatively cumbersome.

[0003] Chinese invention patent application number 201610780523.1 proposes a paper feeding mechanism for a medical laser film printer, capable of feeding materials for various printer models, thereby improving the independent load-bearing capacity of materials and reducing the cost of installing a paper feeding mechanism in the printer. However, the above technology can only achieve unidirectional paper feeding, which is difficult to meet actual printing needs. Summary of the Invention

[0004] To meet the need for feeding paper to multiple printers, this invention proposes an efficient and uniform automatic paper dispenser and its usage method.

[0005] The technical problem to be solved by this invention is achieved by the following technical solution:

[0006] An efficient and uniform paper dispenser includes a dispensing platform with several inclined slides and a sliding hanger. A double-layer paper storage rack is fixedly installed at the bottom of the hanger. A hydraulic cylinder I connected to the hanger is also installed on the dispensing platform. A drive assembly is mounted on the hanger, connected to a lifting plate, and a paper feed control assembly is mounted on the lifting plate. A printer can be installed in front of each inclined slide. The upper part of the double-layer paper storage rack is used to store printing paper. The drive assembly drives the lifting plate to move, thereby providing subsequent paper feeding. The paper feed control assembly is used for paper feeding and separation. The inclined slides are closely arranged in the horizontal direction.

[0007] As a further improvement of the present invention, the inclined slides are arranged horizontally; the dispensing platform is provided with a bottom groove for slidingly mounting the double-layer paper storage rack. The above structure is a conventional design for a sliding structure.

[0008] As a further improvement of the present invention, the driving assembly includes a No. I motor mounted on the hanger, a lead screw connected to the No. I motor, and a guide rail fixedly mounted on the upper side of the hanger; a lifting plate is connected to the lead screw, and the lifting plate is slidably mounted on the guide rail. The lead screw is rotatably mounted on the hanger. The lifting plate can be driven to move back and forth through the lead screw and nut transmission.

[0009] As a further improvement of the present invention, the paper feeding control assembly includes a push rod hinged to the upper side of the lifting plate and a hydraulic cylinder II; the hydraulic cylinder II is hinged to the middle of the push rod. That is, by pushing and pulling the hydraulic cylinder II, the lower part of the push rod can be moved.

[0010] As a further improvement of the present invention, the paper feeding control assembly further includes a drive assembly mounted on the lower part of the push rod and a paper feeding roller connected to the drive assembly; the drive assembly includes two steering shafts rotatably mounted on the lower part of the push rod; the lower steering shaft of the two steering shafts is connected to the paper feeding roller. That is, the movement of the lower part of the push rod allows the paper feeding roller to press the uppermost piece of paper, thereby ensuring effective paper feeding. The drive assembly is used to drive the paper feeding roller to rotate.

[0011] As a further improvement of the present invention, the drive assembly also includes two pulleys respectively mounted on the steering shaft, a drive belt connecting the two pulleys, and a No. II motor connected to the upper steering shaft of the two steering shafts. That is, the rotation of the paper feed roller is achieved by the drive of the No. II motor and the transmission of the drive belt.

[0012] As a further improvement of the present invention, motor II is fixedly mounted on the push rod; of the two pulleys, the diameter of the upper pulley is larger than that of the lower pulley. That is, differential transmission can be formed through the diameter difference of the two pulleys, driving the paper feeding roller to rotate at high speed.

[0013] As a further improvement of the present invention, the upper part of the double-layer paper storage rack is provided with a U-shaped groove, and a U-shaped limiting plate that can be raised and lowered and slidably is provided in the U-shaped groove. The U-shaped limiting plate is connected to a cylinder installed at the lower part of the double-layer paper storage rack. The function of the U-shaped limiting plate is to limit the printing paper stored on the double-layer paper storage rack, so that the printing paper is stacked neatly. The ability to raise and lower the U-shaped limiting plate is to ensure that the push rod will not interfere with the U-shaped limiting plate when the height of the paper stack is reduced as paper is supplied.

[0014] As a further improvement of the present invention, the upper right end of the double-layer paper holder abuts against the upper left end of any inclined slide. This structure is a conventional design for receiving printing paper.

[0015] The beneficial effects of this invention are:

[0016] This invention, by controlling the rotation, forward and backward movement, and downward pressure of the paper feed rollers, and by controlling the translation of the hanger and the slight descent of the U-shaped limiting plate, can achieve automatic paper delivery to multiple printers, meet the needs of actual emergency printing, and also efficiently and evenly distribute the paper.

[0025] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described more clearly and completely below with reference to the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present invention and not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0026] like Figure 1As shown, an automatic paper dispenser for efficient and uniform paper distribution includes a dispensing platform 1, on which several inclined slides 18 and a slidable hanger 3 are mounted. A double-layer paper storage rack 2 is fixedly mounted on the lower part of the hanger 3. A hydraulic cylinder 4 connected to the hanger 3 is also mounted on the dispensing platform 1. A drive assembly is mounted on the hanger 3, which is connected to a lifting plate 5. A paper feed control assembly is mounted on the lifting plate 5. A printer can be installed in front of each inclined slide 18. The upper part of the double-layer paper storage rack 2 is used to store printing paper. The drive assembly is used to drive the lifting plate 5 to move, thereby providing subsequent paper feeding. The paper feed control assembly is used for paper feed and separation. The inclined slides 18 are closely arranged in the horizontal direction.

[0027] like Figure 1 As shown, the inclined slides 18 are arranged horizontally; the dispensing table 1 is provided with a bottom groove 1a for slidingly mounting the double-layer paper storage rack 2. The above structure is a conventional design of a sliding structure.

[0028] like Figure 2 and Figure 4 As shown, the driving assembly includes a No. 1 motor 6 mounted on the hanger 3, a lead screw 7 connected to the No. 1 motor 6, and a guide rail 8 fixedly mounted on the upper side of the hanger 3; the lifting plate 5 is connected to the lead screw 7 and is slidably mounted on the guide rail 8. The lead screw 7 is rotatably mounted on the hanger 3. The lifting plate 5 can be driven to move back and forth through the lead screw nut transmission.

[0029] like Figure 4 As shown, the paper feeding control assembly includes a push rod 9 and a hydraulic cylinder II 10, both hingedly mounted on the upper side of the suspended frame 5; the hydraulic cylinder II 10 is hinged to the middle of the push rod 9. That is, by pushing and pulling the hydraulic cylinder II 10, the lower part of the push rod 9 can be moved.

[0030] like Figure 1 and Figure 3 As shown, the paper feeding control assembly further includes a drive assembly mounted on the lower part of the push rod 9 and a paper feeding roller 11 connected to the drive assembly. The drive assembly includes two steering shafts 12 rotatably mounted on the lower part of the push rod 9; the lower steering shaft 12 is connected to the paper feeding roller 11. That is, the movement of the lower part of the push rod 9 allows the paper feeding roller 11 to press against the uppermost piece of paper, thereby ensuring effective paper feeding. The drive assembly is used to drive the paper feeding roller 11 to rotate.

[0031] like Figure 3 As shown, the drive assembly also includes two pulleys 13 respectively mounted on the steering shaft 12, a drive belt 14 connecting the two pulleys 13, and a No. II motor 15 connected to the upper steering shaft 12 of the two steering shafts 12. That is, the rotation of the paper feed roller 11 is achieved by the drive of the No. II motor 15 and the transmission of the drive belt 14.

[0032] like Figure 3 As shown, motor II 15 is fixedly mounted on push rod 9; of the two pulleys 13, the diameter of the upper pulley 13 is larger than that of the lower pulley 13. That is, differential transmission can be formed through the diameter difference of the two pulleys 13, driving the paper feeding roller 11 to rotate at high speed.

[0033] like Figure 5 and Figure 6 As shown, the upper part of the double-layer paper storage rack 2 is provided with a U-shaped groove 2a, and a U-shaped limiting plate 16 that can be raised and lowered and slidably is provided in the U-shaped groove 2a. The U-shaped limiting plate 16 is connected to a cylinder 17 installed at the lower part of the double-layer paper storage rack 2. The function of the U-shaped limiting plate 16 is to limit the printing paper stored on the double-layer paper storage rack 2, so that the printing paper is stacked neatly. The ability to be raised and lowered of the U-shaped limiting plate 16 is to ensure that the push rod 9 will not interfere with the U-shaped limiting plate 16 when the height of the paper stack is reduced as paper is supplied.

[0034] like Figure 1 As shown, the upper right end of the double-layer paper holder 2 abuts against the upper left end of any inclined slide 18. This structure is a conventional design for receiving printing paper.

[0035] Before using this invention, simply set the inlets of several printers on the front side of each inclined slide 18.

[0036] The specific steps for using it are as follows:

[0037] Step 1: Neatly stack the printing paper on the double-layer paper holder 2, and use the U-shaped limiting plate 16 to limit the printing paper on three sides.

[0038] Step 2: Hydraulic cylinder 10 pushes push rod 9, causing paper feed roller 11 to press against the rear of the top sheet of the printed paper stack.

[0039] Step 3: While the paper feed roller 11 is driven to rotate at high speed by motor II 15, motor I 6 drives the lead screw 7 to rotate, so that the paper feed roller 11 pushes the uppermost sheet of printing paper forward onto the corresponding inclined slide 18, so that the printing paper enters the corresponding paper inlet of the printer.

[0040] Step 4: Move the paper feed roller 11 back to its original position, and the cylinder 17 drives the U-shaped limit plate 16 to lower the thickness of a single sheet of printing paper.

[0041] Step 5: Hydraulic cylinder 4 pushes and pulls the hanger 3, so that the hanger moves from the rear side of an inclined slide 18 to the rear side of its adjacent inclined slide 18.

[0042] Step 6: Repeat steps 2 through 5 above.

[0043] As another embodiment of the present invention, based on the above, by controlling the horizontal reciprocating sliding of the hanger 3, the paper can be evenly distributed to all printers to meet the needs of efficient printing.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely prisms of the invention.
