Description

Technical Field

[0001] This utility model relates to the field of book printing technology, specifically to a paper cutting machine. Background Technology

[0002] Books, as carriers of knowledge and wisdom, play a vital role, and book printing is an indispensable part of this cultural transmission process. From ancient woodblock printing to modern digital printing, book printing technology has undergone a long and glorious history, continuously promoting the progress and development of human civilization. In the book printing process, books need to be cut by a cutting machine to achieve the specified size and specifications.

[0003] Existing devices have some drawbacks during use. For example, during the cutting process, the cutting blades of existing cutting machines have a certain thickness. In addition, when the cutting blades press down, they exert downward pressure on the paper stack. When cutting relatively thick paper stacks, the thickness of the cutting blades and the downward pressure generated during cutting cause the top of the paper stack to tilt. The tilted part of the paper collapses and scatters on the cutting device's worktable. Therefore, it is necessary to manually collect and sort the collapsed paper, which increases the workload of the operators and reduces cutting efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a paper cutting machine that solves the problem that existing cutting machines have a certain thickness of cutting blade during the cutting process. In addition, when the cutting blade presses down, it will exert downward pressure on the paper stack. When cutting a relatively thick paper stack, the thickness of the cutting blade and the downward pressure generated during cutting will cause the paper at the top of the stack to tilt. The tilted part of the paper will collapse and scatter on the worktable of the cutting device. Therefore, it is necessary to manually collect and sort the collapsed paper, which increases the workload of the operator and reduces the cutting efficiency.

[0005] This utility model provides the following technical solution: a printing paper cutting machine, comprising: Four bases; A cutting table, wherein the cutting table is disposed on the top of four bases; A cutting mechanism, wherein the cutting mechanism is disposed on one side of the upper surface of the cutting table; A limiting component is provided on the cutting table to prevent the printed paper from tipping over when it is being cut by the cutting mechanism.

[0006] As a preferred embodiment of the above technical solution, the limiting component includes support plates fixedly connected to both sides of the upper surface of the cutting table. A transverse moving groove is provided on the inner walls of the two opposing sides of the support plates. A motor is fixedly connected to the outer wall of the two support plates on the side away from the cutting mechanism. An adjusting screw is fixedly connected to the output end of each of the two motors. The ends of the two adjusting screws away from the motors pass through the corresponding outer wall of the support plate and are rotatably connected to it. The ends of the two adjusting screws away from the motors are rotatably connected to the inner wall of the corresponding transverse moving groove. A transverse moving block is slidably connected to the inner side of each of the two transverse moving grooves. The two transverse moving blocks are threaded onto the outer side of the corresponding adjusting screw.

[0007] As a preferred embodiment of the above technical solution, the limiting component includes mounting plates fixedly connected to the inner walls of opposite sides of two transverse moving blocks. A rotating rod is provided between the tops of the two mounting plates. The two opposite ends of the rotating rod transversely penetrate the corresponding mounting plates and are rotatably connected to them. Mounting seats are fixedly connected to the outer walls of opposite sides of the tops of the two mounting plates. Cylinders are fixedly connected to the upper surfaces of the two mounting seats. Connecting plates are fixedly connected to the telescopic ends of the two cylinders. Gears are fixedly sleeved on the outer sides of the opposite ends of the rotating rod. Racks are fixedly connected to the bottom ends of the two connecting plates near the cylinders. The two racks mesh with the corresponding gears for transmission.

[0008] As a preferred embodiment of the above technical solution, the limiting component includes a limiting baffle fixedly sleeved on the outside of the rotating rod. Connecting rods are fixedly connected to the outer walls of the opposite sides of the bottom of the limiting baffle. Rollers are rotatably sleeved on the outer sides of the two connecting rods. Arc-shaped guide grooves are opened on the inner walls of the opposite sides of the two mounting plates. The two rollers are slidably connected to the inner side of the corresponding arc-shaped guide groove.

[0009] As a preferred embodiment of the above technical solution, both mounting bases have sliders fixedly connected to their lower end faces, and both racks have grooves on their upper end faces corresponding to the sliders. The two racks are slidably connected to their respective sliders through the corresponding grooves.

[0010] As a preferred embodiment of the above technical solution, a rubber protective pad is fixedly connected to the outer wall of the limiting baffle near the cutting mechanism.

[0011] As a preferred embodiment of the above technical solution, both the limiting baffle and the rubber protective pad have gaps between them and the upper surface of the cutting table.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, before cutting, the limiting baffle rotates around the axis of the rotating rod through the cooperation of the cylinder and rack and pinion transmission mechanism in the limiting assembly, changing from a horizontal state to a state perpendicular to the cutting table. Through the cooperation of the motor and the adjusting screw, the position of the limiting baffle can be precisely controlled and adjusted according to the paper size, ensuring that the limiting baffle can effectively hold the paper stack in place during the cutting process. A rubber protective pad is set on the limiting baffle, which increases the friction with the paper stack, preventing the paper stack from tipping over, and also protects the paper stack from damage to a certain extent. In addition, the distance between the rubber protective pad on the limiting baffle and the paper stack is reserved according to the thickness of the cutting blade, thereby ensuring the accuracy of cutting.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Example like Figures 1-4As shown, this utility model provides a technical solution: a printing paper cutting machine, including four bases 10; a cutting table 11, which is disposed on the top of the four bases 10; a cutting mechanism 12, which is disposed on one side of the upper surface of the cutting table 11; and a limiting component 2, which is disposed on the cutting table 11. The limiting component 2 is used to prevent the printing paper from tipping over when it is cut by the cutting mechanism 12. In specific use, the paper stack to be cut is neatly placed on the cutting table 11, the cutting mechanism 12 is started and the paper stack is cut by the cutting mechanism 12. During the cutting process, the limiting component 2 prevents the paper stack from tipping over. After the cutting is completed, the cutting mechanism 12 is turned off and the cut paper stack is taken out.

[0017] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 4As shown, the limiting component 2 includes support plates 201 fixedly connected to both sides of the upper surface of the cutting table 11. Horizontal moving grooves 202 are laterally formed on the inner walls of opposite sides of the two support plates 201. Motors 203 are fixedly connected to the outer walls of the two support plates 201 away from the cutting mechanism 12. Adjusting screws 204 are fixedly connected to the output ends of the two motors 203. The ends of the two adjusting screws 204 away from the motors 203 pass through the corresponding outer walls of the support plates 201 and are rotatably connected to them. The ends of the two adjusting screws 204 away from the motors 203 are rotatably connected to the inner walls of the corresponding horizontal moving grooves 202. Horizontal moving blocks 205 are slidably connected to the inner sides of the two horizontal moving grooves 202. The moving blocks 205 are threaded onto the outer sides of the corresponding adjusting screws 204. The limiting assembly 2 includes mounting plates 206 fixedly connected to the inner walls of the opposite sides of the two transverse moving blocks 205. A rotating rod 207 is provided between the tops of the two mounting plates 206. The two opposite ends of the rotating rod 207 transversely penetrate the corresponding mounting plates 206 and are rotatably connected to the corresponding mounting plates 206. Mounting seats 208 are fixedly connected to the outer walls of the opposite sides of the tops of the two mounting plates 206. Cylinders 209 are fixedly connected to the upper surfaces of the two mounting seats 208. Connecting plates 210 are fixedly connected to the telescopic ends of the two cylinders 209. Gears 211 are fixedly sleeved on the outer sides of the opposite ends of the rotating rod 207. The bottom of the two connecting plates 210 near the cylinders 209 are fixedly... The two mounting bases 208 are fixedly connected with racks 212, which mesh with corresponding gears 211. Slider blocks 30 are fixedly connected to the lower surfaces of both mounting bases 208. Sliding grooves 31 are formed on the upper surfaces of the two racks 212 corresponding to the sliders 30. The two racks 212 are slidably connected to their respective sliders 30 via the corresponding sliding grooves 31. The limiting assembly 2 includes a limiting baffle 213 fixedly sleeved on the outside of the rotating rod 207. Connecting rods 214 are fixedly connected to the outer walls of the opposite sides of the bottom of the limiting baffle 213. Rollers 215 are rotatably sleeved on the outer sides of the two connecting rods 214. Arc-shaped guide grooves 216 are formed on the inner walls of the opposite sides of the two mounting plates 206. The two rollers 215 are slidably connected to the inner sides of their respective arc-shaped guide grooves 216. A rubber protective pad 40 is fixedly connected to the outer wall of the limiting baffle 213 near the cutting mechanism 12. Both the limiting baffle 213 and the rubber protective pad 40 have gaps between themselves and the upper surface of the cutting table 11. In actual use, before cutting the paper stack, the cylinder 209 is in the extended state, and the limiting baffle 213 and the cutting table 11 are horizontal. Simultaneously, the two cylinders 209 are activated, causing their extension ends to retract and move the corresponding connecting plates 210 towards the cylinders 209. The movement of the two connecting plates 210 causes the corresponding racks 212 to move. The cooperation between the slider 30 and the groove 31 ensures the stability of the racks 212 during movement. The movement of the two racks 212 respectively drives the corresponding gears 211, causing the rotating rod 207 to rotate.The rotation of the rotating rod 207 causes the limiting baffle 213 on it to rotate around the rotating rod 207 as the axis. In addition, the rotation of the limiting baffle 213 is moved along the corresponding arc-shaped guide groove 216 by the rollers 215 that are rotatably sleeved on the outer side of the two connecting rods 214, ensuring the stability of the limiting baffle 213 during rotation. A gap is left to ensure that the limiting baffle 213 and the rubber protective pad 40 are not obstructed by the surface of the cutting table 11 when rotating. When the limiting baffle 213 moves to a position perpendicular to the cutting table 11... When the paper is turned 90 degrees, both cylinders 209 are simultaneously closed. To cut the paper to the required size, both motors 203 are simultaneously started. The outputs of the two motors 203 drive the corresponding adjusting screws 204 to rotate. The rotation of the two adjusting screws 204 causes the corresponding transverse moving blocks 205 to move along the inner side of the corresponding transverse moving grooves 202. The movement of the two transverse moving blocks 205 drives the corresponding mounting plates 206 and the rotating rods 207, limit baffles 213, and mounting bases 2 on the two mounting plates 206. Components such as 08 move. When the limit baffle 213 moves to the appropriate position, the rubber protective pad 40 approaches the paper stack. At this time, both motors 203 are simultaneously turned off, causing the corresponding adjusting screws 204 to stop rotating. The distance between the rubber protective pad 40 and the paper stack is maintained according to the thickness of the cutting blade of the cutting mechanism 12. When the cutting mechanism 12 cuts the paper stack, the rubber protective pad 40 on the limit baffle 213 will press against the paper stack to prevent it from being launched and tipped over. After the paper stack is cut, the mechanism is started simultaneously. Two motors 203 move the limit baffle 213 away from the paper stack. When the limit baffle 213 has moved a certain distance away from the paper stack, both motors 203 are simultaneously turned off. At this time, two cylinders 209 are activated to extend the telescopic end, causing the limit baffle 213 to rotate again around the rotating rod 207 as its axis, until the limit baffle 213 rotates to a horizontal position with the cutting table 11. Then, both cylinders 209 are simultaneously turned off, and the entire system returns to its initial state, ready for the next cutting operation.

[0018] Working principle: The paper stack to be cut is neatly placed on the cutting table 11. Before cutting, the cylinder 209 is in the extended state and the limiting baffle 213 is horizontal with the cutting table 11. Simultaneously, the two cylinders 209 are activated, causing their extension ends to retract and move the corresponding connecting plates 210 towards the cylinders 209. The movement of the two connecting plates 210 causes the corresponding racks 212 to move. The movement of the two racks 212 respectively drives the corresponding gears 211, causing the rotating rod 207 to rotate. The rotation of the rotating rod 207 causes the limiting baffle 213 on it to rotate around the rotating rod 207 as the axis. The rotation of the stop plate 213 is achieved by the rollers 215, which are rotatably connected to the outer sides of the two connecting rods 214, moving along the corresponding arc-shaped guide grooves 216 to ensure the stability of the stop plate 213 during rotation. When the stop plate 213 moves to a 90-degree angle perpendicular to the cutting table 11, the two cylinders 209 are simultaneously closed. Based on the required paper size, the two motors 203 are simultaneously started. The outputs of the two motors 203 drive the corresponding adjusting screws 204 to rotate. The rotation of the two adjusting screws 204 drives the corresponding transverse moving blocks 205 to move along the inner side of the corresponding transverse moving grooves 202. The movement of the two transverse moving blocks 205... The motor drives the corresponding mounting plate 206 and the rotating rods 207, limit baffles 213, and mounting bases 208 on the two mounting plates 206 to move. When the limit baffle 213 moves to the appropriate position, the rubber protective pad 40 approaches the paper stack. At this time, the two motors 203 are simultaneously turned off, causing the corresponding adjusting screws 204 to stop rotating. The distance between the rubber protective pad 40 on the limit baffle 213 and the paper stack is maintained according to the thickness of the cutting blade of the cutting mechanism 12. At this time, the cutting mechanism 12 is started and the paper stack is cut by the cutting mechanism 12. When the cutting mechanism 12 cuts the paper stack, the limit baffle 213... The rubber protective pad 40 will hold the paper stack in place to prevent it from tipping over. After the paper stack is cut, the cutting mechanism 12 is turned off, and then the two motors 203 are started simultaneously to move the limit baffle 213 away from the paper stack. When the limit baffle 213 moves away from the paper stack, and after it has moved a certain distance, the two motors 203 are turned off simultaneously. At this time, the two cylinders 209 are started to extend the telescopic end, so that the limit baffle 213 rotates again around the rotating rod 207 as the axis until the limit baffle 213 rotates to a state that is horizontal with the cutting table 11. At this time, the two cylinders 209 are turned off simultaneously, and the entire system returns to the initial state, ready for the next cut.
