Description

Technical Field

[0001] This utility model relates to the field of book cutter technology, specifically a high-efficiency paper conveying and pressing book cutter. Background Technology

[0002] In the printing, binding, and paper processing industries, book trimmers are key equipment for batch, high-precision cutting of books and stacks of paper. Their core function is to ensure neat edges and uniform dimensions of the finished products. Simultaneously, their automated design significantly improves production efficiency, making them widely used in large printing plants, bookbinding plants, and packaging plants. Existing book trimmers typically use a movable pusher to move the books to be cut under the cutters, and then three sets of cutters cut the three sides of the book to meet the required dimensions. However, current book cutters have significant technical challenges in actual operation: On the one hand, the movable pusher plate needs to stop after pushing the book to be cut to a designated position below the cutter so that the cutter can perform the cutting action. However, the book generates inertia during the pusher plate's movement, which can cause the book to continue moving forward after the pusher plate stops, resulting in the book deviating from the preset cutting position. This directly affects the cutting accuracy and leads to quality problems such as finished product size deviation and rough edges. On the other hand, after cutting, the movable pusher plate needs to continue pushing the cut book to the conveyor mechanism for subsequent transport. If a structure is set up to block the book in the travel path to prevent it from shifting due to inertia, it will hinder the normal transport of the book and cause the equipment to jam. If a mechanically automated blocking structure is used to dynamically control the blocking timing, it can alleviate the above problems, but it will significantly increase the manufacturing cost and maintenance difficulty of the equipment, which is not conducive to the large-scale promotion and application of the equipment.

[0003] Therefore, this utility model provides a high-efficiency paper conveying and book cutting machine. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a high-efficiency paper conveying and book cutting machine to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency paper conveying and book cutting machine, comprising a book cutting machine and a cutting chamber. A book feeding platform is embedded in the book cutting machine. A slider is located at the top of the book feeding platform. A track hole is opened at the top of the book feeding platform. The slider is slidably connected to the inner wall of the track hole and the top of the book feeding platform. A push plate is installed at one end of the slider. A pressure plate for pressing and fixing the book is slidably connected to one side of the push plate. A trapezoidal plate is installed on the inner wall of the bottom side of the book feeding platform. A column is installed at the top of the slider. A pry bar is rotatably connected to the inner side of the column. A movable slide rod for adjusting the up and down movement of the pressure plate is slidably connected to the inner wall of the pry bar. A support bracket that connects to the movable slide rod is installed at the top of the pressure plate. A top rod is hinged to one end of the pry bar. One end of the top rod is located inside the book feeding platform. The top rod is slidably connected to the top surface and two inclined surfaces of the trapezoidal plate. The top rod penetrates the bottom of the slider.

[0006] Preferably, the inner wall of the book delivery platform is equipped with two fixed support plates, and a U-shaped bottom bracket is provided between the two fixed support plates. A lead screw is threadedly connected to the inner wall of the U-shaped bottom bracket, and the lead screw is rotatably connected between the two fixed support plates. A drive part corresponding to the position of the lead screw is installed on the side wall of one of the fixed support plates, and the slider is installed on the top of the U-shaped bottom bracket.

[0007] Preferably, the push plate has a clearance hole, and the movable slide rod is slidably connected to the inner wall of the clearance hole.

[0008] Preferably, two T-shaped sliders are installed on one side of the pressure plate, and two guide grooves are opened on the push plate. The two T-shaped sliders are slidably connected to the inner wall of the corresponding guide groove.

[0009] Preferably, a roller is installed at the bottom of the top rod, and the top rod contacts the surface of the trapezoidal plate through the roller. Beneficial effects

[0010] Compared with the prior art, the present invention has the following advantages: This invention utilizes the mechanical linkage of a trapezoidal plate, a top rod, a pry bar, a movable slide bar, a support bracket, and a pressure plate. When the book reaches the cutting station, the pressure plate automatically presses down and fixes it, solving the problem of cutting position deviation caused by the book's forward movement due to inertia after the push plate stops, thus ensuring cutting accuracy. At the same time, after cutting, the pressure plate automatically moves upward, eliminating the need for fixed obstruction structures or complex automated obstruction devices. This avoids obstructing the normal transport of books and eliminates the need for additional high costs, solving the problems of obstruction structures affecting transport or excessive costs in traditional solutions, and facilitating the large-scale promotion of the equipment.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 A high-efficiency paper conveying and book cutting machine includes a book cutter 1 and a cutting chamber 11. A book feeding platform 2 is embedded in the book cutter 1, and a slider 3 is provided at the top of the book feeding platform 2.

[0015] The top of the book delivery platform 2 has a track bar hole 21. The slider 3 is slidably connected to the inner wall of the track bar hole 21 and the top of the book delivery platform 2. One end of the slider 3 is equipped with a push plate 31, and one side of the push plate 31 is slidably connected to a pressure plate 32 that presses down and fixes the book.

[0016] It should be noted that after the slider 3 described in this embodiment pushes the book to the cutting station, the pressure plate 32 presses down on the book to prevent it from moving forward due to inertia and shaking.

[0017] A trapezoidal plate 22 is installed on the inner wall of the bottom side of the book delivery platform 2. A column 4 is installed on the top of the slider 3. A pry bar 41 is rotatably connected to the inner side of the column 4. A movable slide bar 42 for adjusting the pressure plate 32 is slidably connected to the inner wall of the pry bar 41. A support bracket 321 that connects with the movable slide bar 42 is installed on the top of the pressure plate 32.

[0018] It should be noted that the trapezoidal plate 22 described in this embodiment corresponds vertically to the position of the cutting tool inside the cutting chamber 11.

[0019] One end of the pry bar 41 is hinged to a push rod 43. One end of the push rod 43 is inside the book feeding platform 2. The push rod 43 is slidably connected to the top surface and the two inclined surfaces of the trapezoidal plate 22. The push rod 43 passes through the bottom of the slider 3.

[0020] Specifically, when the book cutter 1 is running, the slider 3 on the book feeding platform 2 slides along the inner wall of the track slot 21 and the top of the book feeding platform 2. The push plate 31 at one end of the slider 3 pushes the book towards the cutting station in the cutting chamber 11. When the slider 3 moves to the trapezoidal plate 22 installed on the bottom inner wall of the book feeding platform 2, the top rod 43, which passes through the bottom of the slider 3 and has one end inside the book feeding platform 2, slides along the top surface and the two inclined surfaces of the trapezoidal plate 22. The lever 41, which is hinged at the other end of the top rod 43, rotates, thereby driving the movable slide rod 42, which is slidably connected to its inner wall, to move up and down. The movable slide rod 42 connects with the support bracket 321 at the top of the pressure plate 32, thus realizing the up and down adjustment of the pressure plate 32 slidably connected to one side of the push plate 31. When the book is pushed to the cutting station, the pressure plate 32 moves downward under the linkage of the above structure, pressing down and fixing the book to prevent it from moving forward and shaking due to inertia, and ensuring the position of the book during cutting. Stable; after cutting, slider 3 continues to drive push plate 31 to move, top rod 43 slides along the inclined surface of trapezoidal plate 22 until it disengages, pry bar 41 resets and causes movable slide bar 42 to drive pressure plate 32 to move upward, no longer pressing on the book, and push plate 31 can smoothly push the cut book to the conveying mechanism. This structure, through the mechanical linkage of trapezoidal plate 22, top rod 43, pry bar 41, movable slide bar 42, support bracket 321 and pressure plate 32, automatically presses down and fixes the book when it reaches the cutting station, solving the problem of the book moving forward due to inertia after push plate 31 stops, which causes the cutting position deviation, and ensures the cutting accuracy; at the same time, after cutting, pressure plate 32 automatically moves upward, without the need to set up a fixed shielding structure or complex automated shielding device, which avoids obstructing the normal transport of books and does not require additional high costs. It solves the problem of shielding structure affecting transport or excessive cost in traditional solutions, which is conducive to the large-scale promotion of equipment.

[0021] In one embodiment of this utility model, such as Figures 1-4 As shown, two fixed support plates 23 are installed on the inner wall of the book delivery platform 2. A U-shaped bottom hanger 5 is provided between the two fixed support plates 23. A lead screw 51 is threadedly connected to the inner wall of the U-shaped bottom hanger 5. The lead screw 51 is rotatably connected between the two fixed support plates 23. A drive part 52 corresponding to the position of the lead screw 51 is installed on the side wall of one of the fixed support plates 23. The slider 3 is installed on the top of the U-shaped bottom hanger 5.

[0022] It should be noted that, in this embodiment, a guide rod symmetrical to the lead screw 51 is provided between the two fixed support plates 23, and the U-shaped bottom hanger 5 slides on the side wall of the guide rod.

[0023] Specifically, the two fixed support plates 23 on the inner wall of the book delivery platform 2 provide installation support for the lead screw 51. When the drive unit 52 runs, it drives the lead screw 51 to rotate between the two fixed support plates 23. Since the inner wall of the U-shaped bottom bracket 5 is threadedly connected to the lead screw 51, and under the constraint of the guide rods symmetrically arranged between the two fixed support plates 23, the U-shaped bottom bracket 5 slides smoothly along the side wall of the guide rod, thereby driving the slider 3 installed at its top to slide along the track strip hole 21 of the book delivery platform 2, so as to realize the push plate 31 to push the book.

[0024] In one embodiment of this utility model, such as Figures 1-4 As shown, a clearance hole 311 is provided on the push plate 31, and the movable slide rod 42 is slidably connected to the inner wall of the clearance hole 311.

[0025] Specifically, a clearance hole 311 is provided on the push plate 31, and the movable slide rod 42 is slidably connected to the inner wall of the clearance hole 311. When the pry bar 41 drives the movable slide rod 42 to move up and down to adjust the pressure plate 32, the clearance hole 311 provides a moving channel and guide for the movable slide rod 42, ensuring that the movable slide rod 42 can slide stably along the preset path, avoiding interference between the movable slide rod 42 and the push plate 31 during the movement, ensuring the docking stability of the movable slide rod 42 and the support bracket 321, thereby making the up and down movement of the pressure plate 32 smoother and more precise, ensuring that the pressure plate 32 can accurately press down and fix the book when it reaches the cutting station, and can move up smoothly after cutting without affecting the subsequent pushing of the book by the push plate 31.

[0026] In one embodiment of this utility model, such as Figures 1-4 As shown, two T-shaped sliders 322 are installed on one side of the pressure plate 32, and two guide grooves 312 are opened on the push plate 31. The two T-shaped sliders 322 are slidably connected to the inner wall of the corresponding guide grooves 312.

[0027] Specifically, when the movable slide bar 42 drives the pressure plate 32 to move up and down, the T-shaped slider 322 slides along the inner wall of the guide groove 312, providing precise guidance and limiting for the movement of the pressure plate 32. This ensures that the pressure plate 32 can only move smoothly in the vertical direction, preventing it from shifting or wobbling to the left or right during its up and down movement. This ensures that the pressure plate 32 accurately presses down on the book and maintains a uniform pressure, further improving the book's fixing effect and preventing the book from shifting during cutting due to unstable fixing. It also makes the up and down movement of the pressure plate 32 smoother and prevents it from interfering with the push plate 31, ensuring the stability of the entire cutting process.

[0028] In one embodiment of this utility model, such as Figures 1-4 As shown, a roller 44 is installed at the bottom of the top rod 43, and the top rod 43 contacts the surface of the trapezoidal plate 22 through the roller 44.

[0029] Specifically, a roller 44 is installed at the bottom of the push rod 43. When the slider 3 moves the push rod 43 to the trapezoidal plate 22, the push rod 43 contacts the top surface and the inclined surfaces on both sides of the trapezoidal plate 22 through the roller 44. As the push rod 43 moves with the slider 3, the roller 44 rolls along the surface of the trapezoidal plate 22, converting the sliding friction between the push rod 43 and the trapezoidal plate 22 into rolling friction. This significantly reduces the friction between the two, reduces the resistance and wear of the push rod 43 during movement, and makes the sliding of the push rod 43 along the surface of the trapezoidal plate 22 smoother and more stable. This ensures that the linkage action of the pry bar 41, the movable slide bar 42 and the pressure plate 32 is more precise and reliable, and ensures that the pressure plate 32 can accurately press down or move up at the right time, improving the fixing effect on the book and the stability of the entire equipment operation.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Working principle: When the book cutter 1 is running, the drive unit 52, supported by the fixed support plate 23 on the inner wall of the book feeding platform 2, drives the lead screw 51 to rotate. The U-shaped bottom hanger 5 slides smoothly under the action of the thread of the lead screw 51 and the limiting of the symmetrical guide rod, driving the top slider 3 to slide along the track strip hole 21. The push plate 31 then pushes the book to the cutting position of the cutting chamber 11, which corresponds vertically with the trapezoidal plate 22. As the slider 3 moves, the top rod 43 rolls along the surface of the trapezoidal plate 22 through the bottom roller 44, carrying... The lever 41 rotates, causing the movable slide bar 42 to slide along the clearance hole 311 of the push plate 31. Combined with the support bracket 321, it drives the pressure plate 32 to move. The pressure plate 32 slides vertically along the guide groove 312 through the T-shaped slider 322. After the book arrives at the cutting station, the pressure plate 32 presses down to fix the book and prevents it from shifting due to inertia. After cutting is completed, the top rod 43 disengages from the trapezoidal plate 22, the lever 41 resets and causes the pressure plate 32 to move upward. The push plate 31 pushes the book to the conveying mechanism, achieving efficient and precise cutting.
