Description

Technical Field

[0001] This utility model relates to the field of book and periodical printing technology, specifically a paper cutter for book and periodical printing. Background Technology

[0002] Book and periodical printing is a technology that uses processes such as plate making, inking, and pressing to transfer ink to paper and mass-produce the content of the original manuscript, including text, pictures, photos, and anti-counterfeiting materials. When printing books and periodicals, we usually need to use a paper cutter to cut the paper into the required size.

[0003] Traditional paper cutters for book and magazine printing consist of a paper cutter frame with a paper cutter blade at the top. The paper is cut by applying downward pressure to the paper cutter blade. A pusher plate is located at the rear of the paper cutter frame to push the cut paper forward for easy cutting again.

[0004] The paper cutter used for book and magazine printing has the following disadvantages: in order to ensure the flatness of the paper cut, the paper needs to be arranged manually before each cut, resulting in low cutting efficiency. Therefore, we propose a paper cutter for book and magazine printing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a paper cutter for book printing. The paper cutter uses a motor to drive a lead screw to drive a slider, so that the top plate on the slider presses the paper between the top plate and the baffle to assist in the flatness of the two sides of the paper. This reduces manual intervention and improves the efficiency of paper cutting, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a paper cutter for book and periodical printing, including a paper cutting table;

The left end of the lead screw is rotatably connected to the left side wall of the paper cutting table. The lead screw passes through the threaded hole in the middle of the slider and is threadedly connected to the slider. The input end of the second motor is electrically connected to the output end of the microcontroller to facilitate driving the slider.

[0010] Furthermore, a first electric push rod is provided at the lower rear end of the mounting base on the right side. The telescopic end of the first electric push rod is fixedly connected to the rear end of the guide block, and the front end of the guide block is slidably connected in the guide groove. The input end of the first electric push rod is electrically connected to the output end of the microcontroller to drive the paper cutter to cut the paper.

[0011] Furthermore, each of the left and right front ends of the mounting shell is provided with a sliding groove II, and a pressing plate is slidably connected between the two sliding groove IIs.

A rotating rod is rotatably connected inside the mounting shell, and a uniformly distributed cam is sleeved on the outer surface of the rotating rod to facilitate pressing the paper.

[0012] Furthermore, a first motor is provided at the front right side of the mounting housing. The output shaft of the first motor passes through the round hole on the right side of the mounting housing and is fixedly connected to the rotating rod. The input end of the first motor is electrically connected to the output end of the microcontroller, driving the cam to press down on the pressing plate.

[0013] Furthermore, a second electric push rod is provided at the middle of the rear end of the mounting shell. A push plate is fixedly connected to the front side of the telescopic end of the second electric push rod, and the input end of the second electric push rod is electrically connected to the output end of the microcontroller to push the paper forward.

[0014] Furthermore, an infrared sensor is installed on the upper front side of the mounting base on the right side. The output of the infrared sensor is electrically connected to the input of the microcontroller to detect non-paper objects in front of the paper cutter.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The paper cutter for printing this book and periodical has the following advantages:

[0016] Activate the second electric push rod, causing its telescopic end to push the push plate and move the pre-cut paper to the lower end of the paper cutter. Then, set the length of each movement of the telescopic end of the second electric push rod according to the required paper cutting length. Start the second motor, which drives the lead screw to rotate through its output shaft. This drives the slider to slide to the left within the groove, pushing the paper towards the baffle. This flattens the sides of the paper. The motor drives the lead screw to drive the slider, causing the top plate on the slider to hold the paper between the top plate and the baffle, thus assisting in flattening the sides of the paper. This reduces manual intervention and improves paper cutting efficiency. Attached Figure Description

Sliding grooves 1 are formed on the opposite inner surfaces of the two mounting bases 2. A knife holder 3 is slidably connected between the two sliding grooves 1. A paper cutter 4 is fixedly installed in the mounting groove at the lower end of the knife holder 3. A guide groove 5 is formed at the upper end of the knife holder 3. A sliding groove 20 is formed in the middle of the table surface of the paper cutting table 1. A slider 16 is slidably connected in the sliding groove 20. A top plate 17 is fixedly connected to the upper end of the slider 16. A baffle 24 is provided on the left side of the table surface of the paper cutting table 1, with the baffle 24 corresponding to the left and right positions of the top plate 17. A mounting shell 8 is provided in the middle of the upper end of the paper cutting table 1. A microcontroller 19 is provided in the middle of the right side of the mounting shell 8. The input terminal of the microcontroller 19 is electrically connected to an external power supply. A second motor 1 is provided on the right side inside the paper cutting table 1. 4. A lead screw 15 is provided on the left side of the output shaft of the second motor 14. The left end of the lead screw 15 is rotatably connected to the left side wall of the paper cutting table 1. The lead screw 15 passes through the threaded hole in the middle of the slider 16 and is threadedly connected to the slider 16. The input end of the second motor 14 is electrically connected to the output end of the microcontroller 19. A first electric push rod 6 is provided at the lower rear end of the mounting base 2 on the right side. The telescopic end of the first electric push rod 6 is fixedly connected to the rear end of the guide block 7. The front end of the guide block 7 is slidably connected in the guide groove 5. The input end of the first electric push rod 6 is electrically connected to the output end of the microcontroller 19. Sliding grooves 2 are provided on the front ends of both sides of the mounting shell 8. A pressing plate 21 is slidably connected between the two sliding grooves 2. A guide post 23 is slidably connected to the bottom of each sliding groove 2. The outer surface of the guide post 23 is... Springs 22 are fitted on all surfaces. A rotating rod 10 is rotatably connected inside the mounting shell 8. The outer surface of the rotating rod 10 is fitted with evenly distributed cams 11. A first motor 9 is located at the front right side of the mounting shell 8. The output shaft of the first motor 9 passes through a round hole on the right side of the mounting shell 8 and is fixedly connected to the rotating rod 10. The input end of the first motor 9 is electrically connected to the output end of the microcontroller 19. A second electric push rod 12 is located in the middle of the rear end of the mounting shell 8. A push plate 13 is fixedly connected to the front side of the telescopic end of the second electric push rod 12. The input end of the second electric push rod 12 is electrically connected to the output end of the microcontroller 19. An infrared sensor 18 is located at the upper front side of the mounting base 2 on the right side. The output end of the infrared sensor 18 is electrically connected to the input end of the microcontroller 19. The pre-cut paper is placed on the paper cutting table 1. On the table, the second electric push rod 12 is activated by the microcontroller 19, causing its telescopic end to move forward. This pushes the pre-cut paper to the lower end of the paper cutter 4 via the push plate 13. The telescopic end of the second electric push rod 12 is then set to travel the required length each time. The microcontroller 19 then activates the second motor 14, whose output shaft drives the lead screw 15 to rotate. This drives the slider 16 to slide the top plate 17 to the left within the groove 20, pushing the paper towards the baffle 24. This flattens both sides of the paper. The front end of the paper is then neatly arranged. Finally, the microcontroller 19 activates the first motor 9, which drives the cam 11 on the rotating rod 10 to rotate. When the center end of the cam 11 reaches the lower end...Cam 11 contacts and presses the pressing plate 21, causing the pressing plate 21 to slide downwards within the sliding groove, thereby compressing the spring 22, causing the spring 22 to contract, and forcing the guide post 23 to slide downwards. At this time, the lower end of the pressing plate 21 contacts and presses the paper. Then, the microcontroller 19 activates the infrared sensor 18, which emits infrared detection information at the front end of the paper cutter 4. If an object approaches the paper cutter 4 before it cuts, the infrared sensor 18 will feed back the information to the microcontroller 19, causing the microcontroller 19 to adjust... All electrical appliances are shut down to prevent accidents. Then, the microcontroller 19 activates the first electric push rod 6. The telescopic end of the first electric push rod 6 drives the guide block 7 to move to the left within the guide groove 5. When the guide block 7 moves to the high groove on the left side of the guide groove 5, it drives the knife holder 3 to move downwards within the sliding groove, thus cutting the paper. The motor drives the lead screw to power the slider, causing the top plate on the slider to hold the paper between the top plate and the baffle, assisting in smoothing the flatness of the paper's sides. This reduces manual intervention and improves paper cutting efficiency.

[0027] The working principle of the paper cutter for book and magazine printing provided by this utility model is as follows: When paper cutting is required for book and magazine printing, the paper cutting operator first places the pre-cut paper on the cutting table 1. Then, the microcontroller 19 starts the second electric push rod 12, causing the telescopic end of the second electric push rod 12 to move forward. The push plate 13 pushes the pre-cut paper to the lower end of the paper cutter 4. Then, the telescopic end of the second electric push rod 12 is set to travel a certain length each time according to the required cutting length. The microcontroller 19 then starts the second motor 14. The output shaft of the second motor 14 drives the lead screw 15 to rotate, thereby driving the slider 16 to slide the top plate 17 to the left in the slide groove 20, thus pushing the paper towards the baffle 24, thereby flattening both sides of the paper. Then, the front end of the paper is neatly arranged. The microcontroller 19 then starts the first motor 9, which drives the cam 11 on the rotating rod 10. When the cam 11 rotates to its lower end, it contacts and presses the pressing plate 21, causing the pressing plate 21 to slide downwards in the sliding groove 2. This compresses the spring 22, causing it to contract and forcing the guide post 23 to slide downwards. At this time, the lower end of the pressing plate 21 contacts and presses the paper. Then, the microcontroller 19 activates the infrared sensor 18, which emits infrared detection information at the front end of the paper cutter 4. If an object approaches the paper cutter 4 before it cuts, the infrared sensor 18 will send the information back to the microcontroller 19, causing the microcontroller 19 to control all electrical components to stop operating to prevent accidents. Then, the microcontroller 19 activates the first electric push rod 6. The telescopic end of the first electric push rod 6 drives the guide block 7 to move to the left in the guide groove 5. When the guide block 7 moves to the high groove on the left side of the guide groove 5, it will drive the knife holder 3 to move downwards in the sliding groove 1, thereby cutting the paper.

[0028] It is worth noting that the microcontroller 19 disclosed in the above embodiments can be an STM32 series, the second electric actuator 12 can be an FY011D, the first electric actuator 6 can be an LAP, the first motor 9 can be a QDTG62-24 (36 / 48), the second motor 14 can be an 110BYGH1.8, and the infrared sensor 18 can be an NI10-EM18WD-AP6X. The microcontroller 19 controls the operation of the second electric actuator 12, the first electric actuator 6, the second motor 14, and the first motor 9 using methods commonly used in the prior art.
