Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a rotating document feeding and printing platform for a document printer. Background Art

[0002] A printer is one of the output devices of a computer, used to print the processing results of the computer on relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed, and noise. There are many types of printers, which are classified into column printers, spherical printers, inkjet printers, thermal printers, laser printers, electrostatic printers, magnetic printers, light-emitting diode printers, etc. according to the technologies adopted. Currently, when many documents need to be printed and copied or something needs to be printed on the documents, printing is required. Currently, when printing documents, generally the documents are placed on the printing platform. However, since there are many types of current documents and most documents are thick, the number of documents stacked on the document feeding platform of the printer is small, and it is necessary to frequently replenish the documents, and the continuity of replenishing materials is poor.

[0003] For example, a rotating document feeding and printing platform for a document printer disclosed in Chinese patent literature (Publication No.: CN220482885U). Although this patent monitors the documents through an infrared sensor, if the documents on the left side are used up, the infrared sensor will transmit a signal to the controller and control the motor to work through the controller. Then, through the transmission of the second gear, the first gear, and the connecting shaft, the documents stacked full on the right side are used for replacement. Through the cyclic alternate replenishment of two groups of documents, the continuity of document feeding is ensured.

[0004] However, in the actual operation process, when the documents on one-sided feeding plate are consumed, the other side rotates for feeding. At this time, it is necessary to replenish the documents. Although the problem of stopping the machine for replenishing materials after the documents are consumed is avoided, a single replenishment of documents is still required frequently through two feeding plates, which will consume a lot of time in document replenishment, and thus reduce the document printing efficiency.

[0005] Therefore, we propose a rotating document feeding and printing platform for a document printer. Content of the Utility Model

[0029] Example 1

[0030] like Figures 1-6 As shown, the utility model provides a technical solution: a rotating card printing platform of a document printer, comprising a fixed base 1, a rotating tube 2 is installed on the upper surface of the fixed base 1 through a bearing, the rotating tube 2 is positioned and rotated by the cooperation of the bearing, one end of the rotating tube 2 passes through and extends to the inside of the fixed base 1, a driving wheel 3 is fixedly sleeved on the outer surface of one end of the rotating tube 2, and a toggle groove 4 and an arc-shaped limit groove 5 distributed in a ring array are respectively opened on the outer surface of the driving wheel 3, the outer surface of the rotating tube 2 is fixedly connected with a connecting block 6 distributed in a ring array, and one end of the connecting block 6 is fixedly connected with a material storage box 7;

[0031] The inner bottom wall of the fixed base 1 is provided with a rotating card pushing device, and the rotating card pushing device includes a column 8 , and the lower end of the column 8 is fixedly connected to the inner bottom wall of the fixed base 1 .

[0032] Example 2

[0033] As Figures 1-6 shown, the utility model provides a technical solution: the upper end of the vertical column 8 penetrates through the rotating pipe 2 and extends to the upper surface of the fixed base 1. The upper end of the vertical column 8 is fixedly connected with a mounting plate 81. The upper surface of the mounting plate 81 is fixedly installed with a servo electric cylinder 82. One end of the piston rod of the servo electric cylinder 82 is fixedly connected with a push plate 83. The vertical column 8 plays a role in fixedly supporting the mounting plate 81.

[0034] One end of the push plate 83 is provided with a mounting groove. The inner wall of the mounting groove is fixedly installed with an infrared sensor 84. The upper surface of the mounting plate 81 is fixedly connected with a detection rod 85. The infrared sensor 84 works after the push plate 83 retracts each time, and the working time each time can be controlled within three seconds.

[0035] The lower surface of one end of the detection rod 85 is fixedly installed with a first infrared pair of light switches 86. The upper surface of the fixed base 1 is fixedly installed with a second infrared pair of light switches 87. The inner bottom wall of the fixed base 1 is fixedly installed with a servo motor 88. After the first infrared pair of light switches 86 and the second infrared pair of light switches 87 receive signals by opposite irradiation, an external warning light is started through an external PLC controller to remind the operator to add certificates.

[0036] The output shaft of the servo motor 88 is fixedly installed with a rotating shaft 89 through a coupling. One end of the rotating shaft 89 is fixedly connected with a mounting sleeve 810. The inner wall of the mounting sleeve 810 is movably sleeved with a telescopic block 811. The upper surface of the telescopic block 811 is fixedly connected with a lever 812. The telescopic block 811 contracts into the mounting sleeve 810 when the lever 812 is subjected to extrusion force.

[0037] One end of the telescopic block 811 is fixedly connected with a compression spring 813. One end of the compression spring 813 is fixedly connected with one side inner wall of the mounting sleeve 810. The front and back of the mounting sleeve 810 are fixedly connected with symmetrically distributed support rods 814. One end of each of the two support rods 814 is fixedly connected with an arc-shaped limiting block 815. The rotation of the mounting sleeve 810 drives the arc-shaped limiting block 815 to rotate through the support rod 814.

[0038] The outer surface of the arc-shaped limiting block 815 is in rotational contact with the inner wall of one of the arc-shaped limiting grooves 5. An arc-shaped blocking block 816 is arranged between adjacent two storage boxes 7. The inner bottom wall of the storage box 7 is provided with a through hole 817. The two side surfaces of the storage box 7 are provided with symmetrically distributed push card slots 818. The storage box 7 is provided with symmetrically distributed through grooves to facilitate the placement of certificates.

[0039] By rotating the card pushing device, the automatic pushing and loading of the documents is achieved, and the multiple storage boxes 7 are rotated and switched for use, thereby avoiding the need for operators to frequently load the documents and improving the efficiency of document printing. When the last document in the storage box 7 is used, the signal reception of the first infrared beam switch 86 and the second infrared beam switch 87 reminds the staff to load the documents in time.

[0040] The utility model workflow:

[0041] Step 1: When loading, the push plate 83 is driven to extend through the piston rod of the servo electric cylinder 82. The movement of the push plate 83 allows it to be inserted into the push card slot 818 and pushes out the document at the bottom of the storage box 7 for loading. After loading, the piston rod of the servo electric cylinder 82 drives the push plate 83 to retract. After retraction, the infrared sensor 84 works to detect whether there are any documents in the storage box 7 through the push card slot 818. At this time, the upper document moves downward by gravity to facilitate subsequent pushing. When the last document in one of the storage boxes 7 is pushed out, the infrared sensor 84 detects that the material has been used up, and starts the servo motor 88 to drive the rotating shaft 89 to rotate one circle.

[0042] Step 2: The rotation of the rotating shaft 89 drives the lever 812 to rotate through the installation sleeve 810. The rotation of the lever 812 inserts it into the toggle slot 4 to drive the driving wheel 3 to rotate. When the lever 812 rotates, the elastic force of the contraction spring 813 drives the telescopic block 811 to retract and cooperate. After the driving wheel 3 rotates a quarter of a circle, the lever 812 disengages from the toggle slot 4, and the arc-shaped limit block 815 rotates to limit the driving wheel 3 in the arc-shaped limit slot 5. The rotation of the driving wheel 3 drives the material storage box 7 to rotate and switch through the connecting block 6. When rotating and switching, the first infrared radiation switch 86 and the second infrared radiation switch 87 are blocked by the arc-shaped stop block 816.

[0043] Step three, when the last storage box 7 containing the documents moves to one end of the push plate 83, one of the remaining three storage boxes 7 will move between the first infrared beam switch 86 and the second infrared beam switch 87, and receive the signal through the connection of the through hole 817, so as to activate the external prompt light through the external PLC controller to light up, reminding the staff to add documents and load the materials.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
