Description

Technical Field

[0001] The utility model relates to a card mounting machine, in particular to a multiple paper feeding detection mechanism of the card mounting machine. Background Art

[0002] A card laminating machine is a special device used to laminate paper. During the processing, a single sheet of paper needs to be fed into the processing station for laminating through a paper feeding mechanism. At present, during the paper feeding process, due to the friction between the stacked papers, two or more sheets of paper may be fed in at the same time in the card laminating machines on the market, affecting the subsequent normal laminating operation. Moreover, this situation of multiple sheets of paper being mis-fed can only be discovered when the paper is stuck or fed out, which will cause paper waste. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a multiple paper feeding detection mechanism of a card mounting machine for solving the above-mentioned problem.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0005] A multiple paper feed detection mechanism for a card mounting machine, characterized in that it includes a first wheel seat and a second wheel seat, a first paper feeding wheel is rotatably arranged on the first wheel seat, a second paper feeding wheel is rotatably arranged on the second wheel seat, one end of the first wheel seat is rotatably arranged on a frame, a first elastic member is arranged between the first wheel seat and the frame, the second wheel seat is slidably arranged on the frame, a second elastic member is arranged between the second wheel seat and the frame, the first paper feeding wheel presses the second paper feeding wheel, and the fed paper can pass between the first and second paper feeding wheels, a position sensor is arranged on the second wheel seat, and the position sensor is connected to the device operation controller signal.

[0006] The first elastic member and the second elastic member are both springs.

[0007] The first wheel seat is connected to a first installation shaft, the first installation shaft is provided with a first bearing, and the first paper feeding wheel is sleeved outside the first bearing.

[0008] The second wheel seat is connected with a second installation shaft, the second installation shaft is provided with a second bearing, and the second paper feeding wheel is sleeved outside the second bearing.

[0009] The second mounting shaft is provided with a threaded hole, the mounting plate is screwed to the second mounting shaft through a fastener and the threaded hole, and the position sensor is arranged on the mounting plate.

[0010] The second wheel seat is connected to the slider via a connecting shaft, and the slider is movably arranged in a slide groove on the frame.

[0011] A multiple paper feed detection mechanism of a card mounting machine in the above technical solution elastically sets the positions of the first and second wheel seats and cooperates with a position sensor. When multiple sheets of paper pass between the first and second rollers at the same time, the second wheel seat will be squeezed to move a greater distance. At this time, the position sensor can immediately feedback information to the controller. After receiving the information, the controller can control the equipment to stop, ensuring that the paper will not be misprocessed or jammed, thereby avoiding paper waste.

[0015] As shown in the figure, the utility model discloses a multi-paper feeding detection mechanism of a card mounting machine, comprising a first wheel seat 13 and a second wheel seat 6, a first paper feeding wheel 10 is rotatably arranged on the first wheel seat 13, a first mounting shaft 12 is connected to the first wheel seat 13, a first bearing 11 is arranged on the first mounting shaft 12, the first paper feeding wheel 10 is sleeved outside the first bearing 11, and the first paper feeding wheel 10 is rotatably supported. A second paper feeding wheel 9 is rotatably arranged on the second wheel seat 6, a second mounting shaft is connected to the second wheel seat 6, a second bearing 7 is arranged on the second mounting shaft, the second paper feeding wheel 9 is sleeved outside the second bearing 7, and the second paper feeding wheel 9 is rotatably supported. One end of the first wheel seat 13 is rotatably arranged on the frame 1, a first elastic member 14 is arranged between the first wheel seat 13 and the frame 1, the second wheel seat 6 is slidably arranged on the frame, the second wheel seat 6 is connected to the slider 15 through the connecting shaft 16, and the slider 15 is movably arranged in the slide groove 3 on the frame to guide the sliding of the second wheel seat 6. A second elastic member 2 is provided between the second wheel seat 6 and the frame, the first paper-feeding wheel 10 presses the second paper-feeding wheel 9, and the fed paper can pass between the first and second paper-feeding wheels. A position sensor 4 is provided on the second wheel seat 6. Specifically, a threaded hole 8 is provided on the second mounting shaft, and the mounting plate 5 is screwed to the threaded hole 8 through a fastener, and the position sensor 4 is provided on the mounting plate 5. In this embodiment, the first elastic member 14 and the second elastic member 2 are both springs, and the position sensor 4 is a photoelectric sensor. The frame can be provided with a sensing part that cooperates with the photoelectric sensor.

[0016] The working principle of the utility model is: when only a single sheet of paper passes between the first paper-passing wheel 10 and the second paper-passing wheel 9, the second wheel seat 6 is squeezed and drives the position sensor 4 to move, and the position sensor 4 feeds back the movement information to the controller. The controller receives a reasonable distance moved by the position sensor 4, indicating that only a single sheet of paper has passed and the equipment is operating normally; when at least two sheets of paper pass between the first and second paper-passing wheels at the same time, the second wheel seat 6 is squeezed and drives the position sensor 4 to move, and the position sensor 4 feeds back the movement information to the controller. When the controller receives a reasonable distance moved by the position sensor 4 exceeding the set value, it means that at least two sheets of paper have entered the equipment at the same time, and the controller will control the equipment to stop and sound an alarm, notifying the staff to take away the multiple sheets of paper fed in at the same time.
