Description

Technical Field

[0001] The invention relates to the technical field of self-service equipment printing, and in particular to a layer paper box of an embedded laser printer. Background Art

[0002] The laser printers currently used in self-service equipment are traditional desktop laser printers: the direction of printing paper is from the back to the front, as shown in the attached Figure 1 As shown in the figure, the paper finally stays in the groove on the upper surface of the laser printer, and the front end of the paper is basically flush with the front end of the printer; when adding paper, pull the paper box forward, and push it back to reset after the paper is loaded, as shown in the attached figure. Figure 2 As shown. This type of laser printer is installed inside the self-service device. If the front end is close to the front door of the device, the printed paper is far away from the outer surface of the device, and there is a long paper output channel, which makes it inconvenient to take paper. Now, it is usually adopted to add a paper feeder to output the paper in a relay manner. This method increases the cost and the probability of paper jams, and paper jams often occur. If the paper output direction of the printer is changed to backward (rotated 180 degrees), that is, the rear cover of the laser printer is opened, and the paper comes out from the rear cover, the channel can be shorter, and there is no need to add a paper feeder, and it is more convenient to take paper. However, the paper box of the desktop laser printer can only be pulled out to the front. After the printer is placed inside the device, the paper box can only be pulled out toward the inside of the cabinet, which is very inconvenient when loading paper. Summary of the invention

[0003] In order to overcome the deficiencies of the above technologies, the present invention provides an embedded laser printer layer paper box which can directly output paper from the rear of the printer and reduce the probability of paper jam.

[0004] The technical solution adopted by the present invention to overcome the technical problems is:

[0005] An embedded laser printer laminate paper box, comprising:

[0006] A fixed layer, a laser printer without a paper box is installed on the fixed layer, a front paper baffle is arranged at the front end of the upper end of the fixed layer in the vertical direction, and side paper baffles are arranged at the left and right sides of the upper end in the vertical direction, the two side paper baffles are parallel, and the distance between the two side paper baffles matches the width of A4 paper;

[0007] A slot I is provided at the rear end of the fixed layer plate, and a movable paper baffle is provided in the slot I along the vertical direction;

[0008] A longitudinal slide groove is arranged at the rear end of the fixed layer plate along the front-back direction, and the handle is slidably installed in the longitudinal slide groove;

[0009] A slot II is arranged on one side of the fixed layer plate, and a paper pickup wheel driving block is arranged in the slot II;

[0010] and a linkage driving device, which is connected to the handle, the movable baffle and the paper feed roller driving block. When the handle is at the rearmost end of the longitudinal chute, the movable baffle is at the rear end of the slot Ⅰ, and the paper feed roller driving block does not contact the tail end of the driving rod of the paper feed roller of the laser printer. When the handle slides forward to the foremost end of the longitudinal chute, the movable baffle is at the front end of the slot Ⅰ, and the distance between the movable baffle and the front baffle matches the length of the A4 paper. The paper feed roller driving block contacts the tail end of the driving rod of the paper feed roller of the laser printer, and the driving rod swings until the paper feed roller contacts the upper surface of the A4 paper.

[0011] For precise positioning, it further includes a positioning pin vertically arranged at the upper end of the fixed layer board, and a pin hole is correspondingly arranged at the lower end of the laser printer. After the laser printer is installed on the fixed layer board, the positioning pin is inserted into the corresponding pin hole.

[0012] To ensure the normal operation of the printer, it further includes a sensor baffle installed at the upper end of the fixed layer board. After the laser printer is installed on the fixed layer board, the sensor baffle is inserted into the sensor groove of the laser printer.

[0013] Furthermore, the above-mentioned linkage driving device includes a limit pin Ⅰ installed at the lower end of the fixed layer board, a bearing Ⅰ rotatably installed on the limit pin Ⅰ, a slide plate, a rotating shaft installed at the lower end of the fixed layer board, and a swing arm. A long hole Ⅰ is arranged on the slide plate in the front-back direction, and the bearing Ⅰ is rollingly arranged in the long hole Ⅰ. The movable baffle is vertically installed on the slide plate. The handle passes through the longitudinal chute in a vertical state and is connected to the slide plate. The middle part of the swing arm is rotatably installed on the rotating shaft. A connecting plate is connected to the outer side end of the swing arm in the vertical direction. The paper feed roller driving block is installed at the upper end of the connecting plate. A long hole Ⅱ is arranged at the inner side end of the swing arm along its length direction. A limit pin Ⅱ is vertically installed at the lower part of the front end of the slide plate. A bearing Ⅱ is rotatably installed on the limit pin Ⅱ, and the bearing Ⅱ is rollingly arranged in the long hole Ⅱ.

[0014] To make the driving process smooth, a guiding inclined surface is arranged at the rear end of the above-mentioned paper feed roller driving block.

[0015] To achieve locking, it further includes a horizontal chute Ⅰ horizontally arranged on the fixed layer board in the left-right direction. The horizontal chute Ⅰ is connected to the front end of the longitudinal chute to form an L-shaped chute. A horizontal chute Ⅱ is horizontally arranged on the slide plate in the left-right direction. The lower end of the handle is slidably installed in the horizontal chute Ⅱ.

[0016] The beneficial effects of the present invention are as follows: When the longitudinal handle moves, it drives the movable baffle forward through the linkage driving device. During the forward movement of the movable baffle, the A4 paper is gradually pushed forward and contacts the front baffle, completing the positioning of the A4 paper. The linkage driving device synchronously drives the paper feed roller driving block to move, making it contact the tail end of the driving rod of the paper feed roller of the laser printer. The paper feed roller driving block moves the tail of the driving rod of the paper feed roller upward, causing the paper feed roller to press down on the A4 paper, which can ensure that the laser printer completes paper feeding and printing. It can achieve adding paper at the back end of the laser printer in the self-service device, meet the direct paper output at the back of the printer, remove the paper feeder, shorten the paper feed channel of the printer, and can achieve paper positioning without paper jamming.

[0026] The following is combined with the attached Figure 1To the appendix Figure 8 To further explain the present invention.

[0027] As shown in the appendix Figure 3 And the appendix Figure 4 As shown, an embedded laser printer laminar paper tray includes: a fixed laminar 2, a laser printer 1 without a paper tray is installed on the fixed laminar 2. At the front end of the upper end of the fixed laminar 2, a front baffle 3 is arranged vertically. On the left and right sides of its upper end, side baffles 6 are respectively arranged vertically. The two side baffles 6 are parallel to each other, and the distance between the two side baffles 6 matches the width of the A4 paper 24. A slot Ⅰ 4 is arranged at the rear end of the fixed laminar 2. An active baffle 5 is arranged vertically in the slot Ⅰ 4. A longitudinal chute 9 is arranged at the rear end of the fixed laminar 2 in the front-rear direction. A handle 11 is slidably installed in the longitudinal chute 9. A slot Ⅱ 26 is arranged on one side of the fixed laminar 2. A paper feed roller driving block 12 is arranged in the slot Ⅱ 26. And a linkage driving device is connected to the handle 11, the active baffle 5 and the paper feed roller driving block 12. When the handle 11 is at the rearmost end of the longitudinal chute 9, the active baffle 5 is at the rear end of the slot Ⅰ 4, and the paper feed roller driving block 12 does not contact the tail end of the driving rod of the paper feed roller of the laser printer 1. When the handle 11 slides forward to the foremost end of the longitudinal chute 9, the active baffle 5 is at the front end of the slot Ⅰ 4. The distance between the active baffle 5 and the front baffle 3 matches the length of the A4 paper 24. The paper feed roller driving block 12 contacts the tail end of the driving rod of the paper feed roller of the laser printer 1, and the driving rod swings to make the paper feed roller contact the upper surface of the A4 paper 24. As shown in the appendix Figure 5 As shown, when in use, the A4 paper 24 is placed on the fixed laminar 2 from the rear end of the laser printer 1 and is located between the two side baffles 6. Then, the handle 11 is driven to slide forward along the longitudinal chute 9. When the longitudinal handle 11 moves, the active baffle 5 is driven to move forward through the linkage driving device. As shown in the appendix Figure 6 As shown, during the forward movement of the active baffle 5, the A4 paper 25 is gradually pushed forward, and it contacts the front baffle 3 to complete the positioning of the A4 paper 25. The linkage driving device synchronously drives the paper feed roller driving block 12 to move, so that it contacts the tail end of the driving rod of the paper feed roller of the laser printer 1. The paper feed roller driving block 12 moves the tail of the driving rod of the paper feed roller upward, so that the paper feed roller presses down on the A4 paper 24, which can ensure that the laser printer 1 completes paper feeding and printing. It can realize adding paper at the rear end of the laser printer 1 in a self-service device, meet the requirement of directly discharging paper at the rear of the printer, can remove the paper feeder, shorten the paper feeding channel of the printer, and can realize the positioning of the paper without paper jamming.

[0028] Preferably, it further includes a positioning pin 7 vertically arranged at the upper end of the fixed layer board 2, and a pin hole is correspondingly arranged at the lower end of the laser printer 1. After the laser printer 1 is installed on the fixed layer board 2, the positioning pin 7 is inserted into the corresponding pin hole. By setting the positioning pin 7, the accuracy of the connection and positioning between the laser printer 1 and the fixed layer board 2 can be improved, and the situation of paper jamming caused by connection misalignment can be prevented.

[0029] Furthermore, it further includes a sensor baffle 8 installed at the upper end of the fixed layer board 2. After the laser printer 1 is installed on the fixed layer board 2, the sensor baffle 8 is inserted into the sensor groove of the laser printer 1. Since the laser printer 1 detects whether the paper tray is installed through the sensor, when the original paper tray is removed, the laser printer 1 can use the fixed layer board 2 as the paper tray by inserting the sensor baffle 8 into the sensor groove of the laser printer 1 to meet the working requirements.

[0030] As shown in the attachment Figure 8 As shown in the figure, the linkage driving device can be of the following structure, which includes a limit pin Ⅰ 16 installed at the lower end of the fixed layer board 2, a bearing Ⅰ 17 rotatably installed on the limit pin Ⅰ 16, a slide plate 14, a rotating shaft 21 installed at the lower end of the fixed layer board 2, and a swing arm 20. A long hole Ⅰ 15 is arranged on the slide plate 14 in the front-back direction, and the bearing Ⅰ 17 is rollingly arranged in the long hole Ⅰ 15. The movable baffle 5 is vertically installed on the slide plate 14. The handle 11 passes through the longitudinal chute 9 in a vertical state and is connected to the slide plate 14. The middle part of the swing arm 20 is rotatably installed on the rotating shaft 21. A connecting plate 23 is connected to the outer end of the swing arm 20 in the vertical direction. The paper feed roller driving block 12 is installed at the upper end of the connecting plate 23. A long hole Ⅱ 22 is arranged at the inner end of the swing arm 20 along its length direction. A limit pin Ⅱ 18 is vertically installed at the lower front part of the slide plate 14. A bearing Ⅱ 19 is rotatably installed on the limit pin Ⅱ 18, and the bearing Ⅱ 19 is rollingly arranged in the long hole Ⅱ 22. When the handle 11 slides forward along the longitudinal chute 9, it drives the slide plate 14 to move forward. When the slide plate 14 moves, the bearing Ⅰ 17 rotates in the long hole Ⅰ 15 to achieve guiding and ensure its movement in the front-back direction. When the slide plate 14 moves forward, its front end drives the swing arm 20 to rotate around the rotating shaft 21 by rolling the bearing Ⅱ 19 in the long hole Ⅱ 22, so as to drive the paper feed roller driving block 12 to rotate until it contacts the tail end of the driving rod of the paper feed roller of the laser printer 1 and drives it to move upward.

[0031] Preferably, a guiding inclined surface 13 is arranged at the rear end of the paper feed roller driving block 12. When the paper feed roller driving block 12 contacts the tail end of the driving rod of the paper feed roller, it can contact the driving rod through the guiding inclined surface 13 to achieve the guiding effect and ensure that the paper feed roller driving block 12 can smoothly contact the paper feed roller driving rod and drive the paper feed roller driving rod to move upward.

[0032] Furthermore, as shown in the attachmentFigure 7 As shown, it further includes a horizontal chute Ⅰ 10 horizontally arranged on the fixed layer board 2 in the left-right direction. The horizontal chute Ⅰ 10 is connected to the front end of the longitudinal chute 9 to form an L-shaped chute. A horizontal chute Ⅱ 25 is horizontally arranged on the slide plate 14 in the left-right direction. The lower end of the handle 11 is slidably installed in the horizontal chute Ⅱ 25. When the handle 11 slides forward to the foremost end of the longitudinal chute 9, at this time, the movable baffle 5 moves to the foremost end, and it and the front baffle 3 limit the A4 paper 24. At this time, slide the handle 11 outward along the horizontal chute Ⅰ 10, and at the same time, the lower end of the handle 11 slides along the horizontal chute Ⅱ 25 to realize the position limit of the handle 11, ensure the locking of the position of the movable baffle 5, prevent its free movement, and improve the reliability of use.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
