Background technique

In schools, especially universities, students are faced with more and more types of examinations, and the number of papers required for each examination is also different. When preparing test papers, the workers in the printing room need to classify and print them according to the number of papers and scores required by the teacher. If the teacher requires 3 test papers, 60 copies are required, and the workers need to print 60 copies of the 3 test papers respectively. Then, according to the binding order of the roll surface, manual twisting of the paper is carried out manually, followed by manual operation with a stapler to complete the binding of a test paper. Therefore, the binding task of the test paper requires a total of 180 times of manual twisting and 60 times of manual binding. After the exam, the teacher also needs to remove the staples of each test paper, bind them neatly and seal them, and then mark the papers. Therefore, each test paper needs to be manually twisted and bound when printing, and it still needs to be manually disassembled after the test. The overall work process has a large workload, time-consuming and labor-intensive, and inconvenient to operate.

See Figures 1, 2, 3 and 6, a paper pick-up mechanism 9 is arranged on the side of the round table top 11, and the paper pick-up mechanism 9 is assembled on the frame 21, and its structure is: a roller bracket 902 is assembled at the paper pick-up port of the frame , the roller bracket 902 is assembled with the paper taking roller 901 driven by the stepper motor II 905, the roller bracket 902 is assembled on the frame through the bracket guide rod 904, and the bracket spring 903 is worn on the bracket guide rod 904; the bracket spring 903 can be Make the paper-fetching roller 901 adapt to the thickness of the paper in the paper storage bin 1, and rotate under the drive of the stepper motor II905 to realize paper-fetching, ensuring that one piece of paper is picked up at a time.

See Figures 1, 2 and 4, a supporting plate 12 is arranged on the top of the frame 21, one end of the supporting plate 12 is hinged on the frame, and the other end is connected with the push-pull electromagnet 15 assembled on the frame, and the push-pull electromagnet 15 controls Whether the supporting plate 12 is opened or not; the gripper mechanism 13 is set on the top of the frame 21: that is, the eccentric wheel 18 driven by the stepper motor III 16 is set on the frame, and the eccentric drive arm 18-1 is set on the eccentric wheel 18, and the eccentric The driving arm 18-1 is inserted into the chute on the rocker 5, the upper end of the rocker 5 is connected to the gripper frame 1302 (see Figure 8), and the gripper frame 1302 is connected to the gripper 1301; the gripper 1301 is two A sharp and small steel needle, when the paper-feeding mechanism 9 completes the paper-fetching, and one end of the paper passes through the paper-feeding roller 14, the paper-grip pin 1301 will pierce the paper, pick up the paper, and extract it to the pallet 12.

See Fig. 1, 2, 7, on the side wall of the frame 21, there is an arc-shaped slot 17, the gripper needle holder 1302 passes through the arc-shaped notch 17 and moves along the arc-shaped notch, and the gripper rocker 5 drives the gripper The paper needle swings back and forth to realize the reciprocating gripping of the gripper mechanism 13; a rubber groove 8 is arranged at the exit end of the test paper binding of the frame, and a paper pressing mechanism 7 is arranged below the glue groove 8, and the paper pressing mechanism 7 is provided with a hinged joint on the frame. Press plate 701 , one end of press plate 701 is connected to press stopper 704 , reset spring 702 and binding rubber tube 703 are arranged under the platen 701 , and binding rubber tube 703 is connected to glue tank 8 . The test paper receiving box 6 is arranged below the pallet 12 . When the gripper rocker 5 moves to the end of the binding, it is pressed against the platen stopper 704 to realize the downward swing of the platen mechanism 7,

The platen 701 presses out the paper on the gripper pin 1301, so that the paper stays on the pallet 12, and then the binding glue tube 703 flows out a certain amount of glue to bond the binding paper; when the gripper rocker 5 returns, the paper stopper The sheet 704 resets under the drive of the spring, and realizes the upward swing of the paper pressing mechanism 7, and the reset elastic sheet 702 on the pressing baffle plate 701 also resets thereupon, preventing the binding of the binding rubber tube 703 and the paper.

See Fig. 1, 4, on frame 21, circuit control box 10 is set, and this circuit control box 10 adopts existing circuit technology. Corresponding switches and gear positions are provided to coordinately control the operation of each stepping motor, push-pull electromagnet 15 and the motor.

The working process of the automatic test paper binding machine of the present invention is as follows:

Suppose you need to complete the binding of 80 5-page paper test papers:

First put 5 dozen sheets of paper into the paper storage bin 1 on the round table top 11 in sequence, and set the number of copies to be bound as 80 copies. Start the test paper binding machine, and the motor drives the pulley to make all the paper storage slots 1 on the round table 11 start to move.

When a paper storage bin 1 moved below the paper taking mechanism 9, the motor stopped moving. The stepper motor I 403 drives the cam 401 to rotate, and the cam 401 raises the paper storage bin 1, so that one end of the paper storage bin 1 contacts the paper pickup roller 901 in the paper pickup mechanism 9, and rotates under the drive of the stepper motor II 905 The paper is picked up, and the paper is pulled into the paper feed roller 14. At the other end of the paper feed roller 14, the paper is pierced by the gripper needle 1301 in the gripper device 13, and the paper is picked up and pulled to the bottom of the paper press mechanism 7. .

When the gripper rocker 5 moves to the binding end point, it works together with the press stopper 704, the press plate 701 presses out the paper on the gripper pin 1301, and the binding glue tube 703 flows out a certain amount of glue for bonding and binding Paper; when the gripper rocker 5 returns, the paper platen 704 resets under the drive of the spring, and the paper platen 7 swings upwards, and the reset spring 702 on the press plate 701 also resets accordingly, and the binding rubber tube 703 and the paper Separate, gripper rocking bar 5 returns according to original track.

Repeat the above process 5 times, after finishing the binding of 5 test papers in sequence, the push-pull electromagnet 15 pulls down one end of the binding baffle 12, so that the 5 bound test papers slide into the test paper receiving box 6, and the round table 11 moves rapidly , to move the paper bin 1 to the initial position.

So far, the above has explained in detail the complete process of delivery, assembly, and binding of a test paper. By repeating the above process 80 times, the binding of 80 5-page test papers is completed.
