[0023] Such as Figure 1As shown in the figure, the present utility model provides a technical solution: a novel square-back device, which includes a mounting bracket 1. A driving mechanism 2 is installed on the upper side in the middle of the mounting bracket 1. A square-back mechanism 3 is installed at the bottom of the driving mechanism 2. A limiting mechanism 4 is installed on the left side of the square-back mechanism 3. A photoelectric sensor 5 is installed in the middle on the right side of the driving mechanism 2. A plurality of proximity switches 6 are installed on each of the left and right sides of the driving mechanism 2. Among them, three proximity switches 6 are installed on the left side and one proximity switch 6 is installed on the right side. The photoelectric sensor 5 is connected to the driving mechanism 2 to drive the driving mechanism 2 to convey exercise books at fixed points. The proximity switches 6 are connected to the limiting mechanism 4 and the square-back mechanism 3 to reciprocally press the exercise books by the square-back mechanism 3, so as to reduce the square-back processing time, ensure that the back flatness of each page is consistent, avoid local unevenness, and at the same time drive the limiting mechanism 4 to rise to align the exercise books and drive the limiting mechanism 4 to descend to convey the exercise books that have been pressed by the square-back mechanism 3 out.
[0024] As Figure 2 and Figure 4As shown, the driving mechanism 2 includes a servo motor 21, seven guide rollers 22, two drive belts 23 and twenty-eight conveyor belts 24. The servo motor 21 is installed on the upper front side of the outer surface of the mounting frame 1. The seven guide rollers 22 are spaced in two rows, upper and lower, on the upper side inside the mounting frame 1, with three guide rollers 22 in the upper row and four guide rollers 22 in the lower row. And the four guide rollers 22 on the left and the three guide rollers 22 on the right are each in a group on the left and right. The two guide rollers 22 on the right side of the upper row and the two guide rollers 22 in the middle of the lower row protrude from the mounting frame 1 at the front side, and pulley wheels are sleeved on the protruding ends. Among them, one pulley wheel is sleeved on the front and back of the guide roller 22 on the right side in the middle of the lower row. A long drive belt 23 is sleeved between the pulley wheels on the left and right guide rollers 22 in the upper row, the pulley wheel on the rear side of the guide roller 22 on the right side in the middle of the lower row, and the servo motor 21. A short drive belt 23 is sleeved between the pulley wheels on the two guide rollers 22 in the middle of the lower row. Fourteen conveyor belts 24 are spacedly sleeved on the four guide rollers 22 on the left, with seven conveyor belts 24 on each of the upper and lower guide rollers 22. Another fourteen conveyor belts 24 are spacedly sleeved on the three guide rollers 22 on the right, with seven conveyor belts 24 sleeved on the upper guide roller 22 and seven conveyor belts 24 provided on the two lower guide rollers 22. A bracket 25 is installed on the top inside the mounting frame 1. An optoelectronic sensor 5 is installed at the bottom in the middle on the left side of the bracket 25. Three proximity switches 6 are spacedly installed at the top in the middle on the left side of the bracket 25. A proximity switch 6 is installed at the bottom on the right side of the bracket 25. A number of mounting holes are provided on the right side of the bracket 25, and seven pulley wheels are spacedly installed in the mounting holes. Among them, the left ends of the seven conveyor belts 24 sleeved on the guide roller 22 on the upper right side are successively sleeved on the seven pulley wheels on the right side of the bracket 25. During use, the servo motor 21 is started to drive the long drive belt 23 to rotate. The rotation of the long drive belt 23 drives the three guide rollers 22 in the upper row to rotate, and at the same time drives the two guide rollers 22 on the right side of the lower row to rotate. The rotation of the two guide rollers 22 on the right side of the lower row further drives the two guide rollers 22 on the left side of the lower row to rotate synchronously through the short drive belt 23. The synchronous rotation of the guide rollers 22 further drives the conveyor belts 24 to rotate synchronously to convey the exercise books between the upper and lower conveyor belts 24 to the square-back mechanism 3. When it is close to the square-back mechanism 3 during transportation, the optoelectronic sensor 5 receives a signal to start the square-back mechanism 3 for reciprocating wheel pressing.
[0025] As Figure 3As shown in the figure, the square back mechanism 3 includes a first cylinder 31, a mounting plate 32, twenty-seven pressure wheels 33, two second cylinders 34 and a pressing plate 35. The first cylinder 31 is installed inside the bracket 25. At the bottom of the front output end of the first cylinder 31, there is a mounting plate 32. Twenty-seven pressure wheels 33 are rotatably installed at equal intervals at the bottom of the mounting plate 32. A connecting plate is installed in the middle of the mounting frame 1. Second cylinders 34 are symmetrically installed on the connecting plate in the front and back. The pressing plate 35 is installed on the second cylinders 34. When in use, when the limiting mechanism 4 blocks and aligns the exercise books, the second cylinder 34 pushes upward to drive the pressing plate 35 to push upward, so that when the exercise books are conveyed by the conveyor belt 24, the pressing plate 35 can support the bottom of the exercise books. At this time, the first cylinder 31 reciprocates forward twice, driving the twenty-seven pressure wheels 33 on the mounting plate 32 to reciprocate twice. The single push stroke is 100 Cm each time and the total stroke is 400 Cm. High-density walking for four strokes generates 120 pressure points. Doubling the pressure points and pressing back and forth makes it flatter. After the reciprocating motion is completed, the 90-degree plate and the pressing plate 35 descend simultaneously to complete the back pressing action. The limiting mechanism 4 moves downward, and the exercise books continue to be conveyed forward under the action of the conveyor belt 24.
[0026] As Figure 4 shown in the figure, the limiting mechanism 4 includes two third cylinders 41, two guide rails 42 and a baffle 43. The third cylinders 41 are symmetrically installed in the front and back on the left side of the pressing plate 35. A guide rail 42 is installed at the corresponding position on the left side of the pressing plate 35. The guide rail 42 is located outside the third cylinder 41. A baffle 43 is installed on the tops of the two third cylinders 41. The baffle 43 slides on the guide rail 42. When the proximity switch 6 receives a signal and starts to push the pressing plate 35 upward, after the proximity switch 6 senses a change in the signal, it starts the third cylinder 41 to push the baffle 43 to move upward along the guide rail 42 to block the exercise books conveyed by the conveyor belt 24, so as to facilitate flattening the exercise books reciprocally by the pressure wheels 33 after alignment. After the wheel pressing is completed, when the proximity switch 6 senses the signal change again, it starts the third cylinder 41 to drive the baffle 43 to reset downward, and the exercise books continue to be conveyed forward under the action of the conveyor belt 24.
[0027] Working principle: When in use, install them in sequence. Start the servo motor 21 to drive the long drive belt 23 to rotate. The rotation of the long drive belt 23 drives the three upper guide rollers 22 to rotate, and at the same time drives the two guide rollers 22 on the right side of the lower row to rotate. The rotation of the two guide rollers 22 on the right side of the lower row further drives the two guide rollers 22 on the left side of the lower row to rotate synchronously through the short drive belt 23. The synchronous rotation of the guide rollers 22 further drives the conveyor belt 24 to rotate synchronously to convey the exercise books between the upper and lower conveyor belts 24 to the square back mechanism 3. When approaching the square back mechanism 3, after the proximity switch 6 senses the signal change, it starts the third cylinder 41 to push the baffle 43 to move upward along the guide rail 42 to block the exercise books transmitted by the conveyor belt 24. When the baffle 43 blocks and aligns the exercise books, the second cylinder 34 pushes upward to drive the pressing plate 35 to push upward, so that when the exercise books are transmitted by the conveyor belt 24, the pressing plate 35 supports the bottom of the exercise books. At this time, the first cylinder 31 reciprocates forward twice, driving the twenty-seven pressure wheels 33 on the mounting plate 32 to reciprocate twice. Each pushing stroke is 100 Cm for a single time and the total stroke is 400 Cm. High-density walking for four strokes generates 120 pressure points. Doubling the pressure points and pressing back and forth makes it flatter. After the reciprocating motion is completed, the 90-degree plate and the pressing plate 35 descend simultaneously to complete the back pressing action. When the proximity switch 6 senses the signal change again, it starts the third cylinder 41 to drive the baffle 43 to reset downward, and the exercise books continue to be conveyed forward under the action of the conveyor belt 24.
