Description

Technical Field

[0001] This utility model relates to the field of edge trimming structure improvement technology for binding drawings, specifically a horizontal and vertical trimming mechanism for the edges of binding drawings. Background Technology

[0002] Blueprints are important documents in industries such as architecture and manufacturing. After they are made, they need to be folded, that is, large-format blueprints are folded according to certain size rules. These folded blueprints can only be archived after being bound, so it is necessary to leave binding edges when folding the blueprints and to trim away any excess edges according to the specifications of the horizontal fold.

[0003] Currently, the cutting equipment is a cutting machine, whose main structure includes a drawing feeding mechanism, a bending mechanism, and a cutting mechanism. The drawing feeding mechanism includes multiple spaced-apart paper pressure rollers. The rotation of these rollers transports the stacked drawing towards the cutting mechanism. The bending mechanism includes guide bending structures that guide the end edges of the stacked drawing towards the cutting mechanism. The cutting mechanism includes transverse and longitudinal trimming structures, which trim the folded ends of the drawing within the cutting mechanism. The above-mentioned cutting mechanism has the following problems:

[0004] 1. The integration of the transverse and longitudinal cutting edge structures is low, and the positioning and operational stability need to be improved;

[0005] 2. The longitudinal cutting edge structure often uses hinge technology, that is, cutting the edge through a scissor-like hinge method. This has poor stability and requires frequent adjustment of the gap between the blades in the longitudinal cutting edge structure.

[0006] 3. The cutting edge range of the longitudinal cutting edge structure is small (≤35 mm), resulting in poor versatility;

[0007] In summary, there is an urgent need for a cutting mechanism that is stable in operation, has a large cutting range, high integration, and good control. Utility Model Content

[0008] The purpose of this utility model is to provide a horizontal and vertical cutting mechanism for the edges of bound drawings, so as to solve the technical problems mentioned in the background art.

[0009] This utility model provides the following technical solution:

[0010] A horizontal and vertical cutting mechanism for the edges of bound drawings includes a fixed frame, characterized in that: a cutting mounting frame is provided on the fixed frame and can slide back and forth along the fixed frame limit, and a horizontal cutting module and a vertical cutting module are provided in the cutting mounting frame;

[0011] The horizontal cutting module and the vertical cutting module can slide synchronously with the cutting and mounting frame, and the vertical cutting module can perform vertical cutting after the horizontal cutting module has cut the horizontal edge.

[0012] Furthermore, the longitudinal cutting module can clamp the longitudinally cut paper strip after completing the longitudinal cutting, and tear off and discard the longitudinally cut paper strip when the cutting and mounting frame is reset.

[0013] Furthermore: the longitudinal cutting module includes a longitudinal moving blade and a longitudinal stationary blade. The longitudinal stationary blade is arranged approximately vertically in the cutting mounting frame below the fixed frame, and its cutting edge is close to or attached to the rear side of the end edge of the stacked pattern that is guided and bent down from above the fixed frame. The longitudinal moving blade is arranged in the cutting mounting frame in front of the front side of the end edge of the stacked pattern. It can slide back and forth in the front-back direction of the cutting mounting frame. When the longitudinal moving blade and the longitudinal stationary blade are in shearing cooperation, they can longitudinally cut the end edge of the stacked pattern.

[0014] Furthermore, the longitudinal cutting module also includes a slider, a longitudinal cutting tool slide rail, a swivel block, a connecting rod, and a longitudinal cutting tool mounting plate;

[0015] A longitudinal blade drive motor is installed on one of the two side walls at the rear of the cutting mounting frame, and a longitudinal blade slide rail that gradually slopes downward from back to front is installed on the other side of the side wall. A slider is slidably installed on the longitudinal blade slide rail, and the slider is connected to the rear end of the longitudinal blade mounting plate. The longitudinal blade is mounted on the side of the longitudinal blade mounting plate located on the front side of the cutting mounting frame, which is extended upward and bent, near the longitudinal stationary blade. The front end of the longitudinal blade mounting plate in front of the slider is hinged to the front end of the connecting rod, and the rear end of the connecting rod is hinged to the front end of the swing block. The rear end of the swing block is connected to the output shaft of the longitudinal blade drive motor.

[0016] Furthermore: the cutting edge of the stationary blade is inclined to the front of the cutting mounting frame, and the cutting edge of the moving blade is inclined to the front of the cutting mounting frame; there is an included angle between the cutting edges of the stationary blade and the moving blade.

[0017] The preferred option is that the included angle is 5-10 degrees.

[0018] A preferred embodiment is that a pressure roller is installed on the side of the longitudinal moving blade near the longitudinal stationary blade. This pressure roller can clamp the longitudinally cut paper strip when the longitudinal moving blade and the longitudinal stationary blade cut the end edge of the stacked image. After the cutting mounting frame starts to reset, the longitudinally cut paper strip can be torn off from the end edge of the stacked image. After the pressure roller resets with the longitudinal moving blade, the paper strip can be discarded.

[0019] A preferred embodiment is that a trigger plate is provided on the bottom side of the longitudinal blade mounting plate, and a longitudinal blade position detection sensor module is installed next to the trigger plate.

[0020] Furthermore: A longitudinal blade compression spring is provided between the side of the longitudinal stationary blade and the longitudinal blade mounted on the side of the upwardly extending bent front end of the longitudinal blade mounting plate located on the front side of the cutting mounting frame.

[0021] Furthermore: the transverse cutting module includes a transverse moving blade and a transverse stationary blade. The transverse stationary blade is mounted transversely on the bottom surface of the fixed frame, and the transverse moving blade is mounted on the cutting mounting frame above the longitudinal moving blade. A portion of the cutting edge of the transverse moving blade is located at the bottom surface of the transverse stationary blade, and the upper end surface of this portion of the cutting edge is spaced apart from or attached to the bottom surface of the transverse stationary blade. The transverse moving blade slides synchronously with the cutting mounting frame and performs transverse cutting on the end edge of the stacked image through shearing cooperation with the transverse stationary blade.

[0022] Furthermore: the transverse blade is a circular blade, which is rotatably mounted on the cutting mounting frame above the longitudinal blade. A portion of the cutting edge of the outer edge of the circular blade is located at the bottom surface of the transverse stationary blade, and the upper end face of this portion of the cutting edge is spaced apart from or attached to the bottom surface of the transverse stationary blade.

[0023] A preferred embodiment is as follows: a roughly vertical transverse blade mounting post is provided on the front end of the cutting mounting frame. The lower end of the transverse blade mounting post, located inside the cutting mounting frame, is fitted with a rotating wheel, a circular blade, a transverse blade spring, and a fixing nut from top to bottom. The fixing nut can tighten the transverse blade spring, which can press the circular blade against the rotating wheel and make the upper end face of the circular blade fit against the bottom face of the transverse stationary blade.

[0024] A preferred embodiment is that an edge detection sensor module for detecting the end of the overlay image is provided in the cutting mounting frame next to the transverse blade mounting column.

[0025] Furthermore: A pressure plate wheel is provided on the cutting mounting frame next to the transverse knife mounting column. The pressure plate wheel slides with the cutting mounting frame and can press down the pressure plate provided on the front side of the fixed frame when sliding. The pressure plate can press down the end of the stacked pattern that is guided and bent down from the top of the fixed frame during cutting.

[0026] Furthermore, the upper rear end of the cutting and mounting frame is provided with a mounting part, which is connected to a traction module arranged horizontally on the fixing frame. The traction module drives the cutting and mounting frame to move horizontally back and forth through the mounting part.

[0027] The preferred solution is that the traction module uses a belt drive or a chain drive.

[0028] A preferred embodiment is that a cutting and mounting frame position detection sensor module is provided below the bottom of the cutting and mounting frame.

[0029] The beneficial effects of this utility model are:

[0030] 1. In this utility model, the transverse cutting structure and the longitudinal cutting structure are integrated and installed inside the cutting and mounting frame. The cutting and mounting frame is set below the fixed frame for transverse limiting and reciprocating sliding. The cutting and mounting frame makes the overall structure more stable, which is beneficial to the stability during high-speed movement and avoids cutting errors caused by vibration, displacement and other factors. The relative positions of the transverse cutting structure and the longitudinal cutting structure are fixed, which is beneficial to the accurate positioning of the cutting position.

[0031] 2. In this invention, the longitudinal blade is driven by a slide rail, connecting rod, and other structures. Compared to traditional hinged methods, it offers better stability during operation, effectively reducing wobbling and deviation during the cutting process and ensuring neat and uniform cutting edges. Furthermore, due to the use of a connection structure different from traditional hinged methods, the cutting edges of both the longitudinal blade and the stationary blade are longer, providing a higher cutting size with a cutting range of 12-50 mm.

[0032] 3. In this utility model, the bent front end of the longitudinal blade mounting plate is connected to the longitudinal blade by two upper and lower fixing bolts. The surface of the fixing bolts located between the bent front end and the longitudinal blade is fitted with a longitudinal blade compression spring. These two longitudinal blade compression springs can hold the longitudinal blade in place and provide it with a stable elastic force, so that the longitudinal blade always maintains a close fit with the longitudinal stationary blade during long-term, high-intensity work. This not only improves the cutting stability but also achieves long-term maintenance-free operation, significantly reducing equipment maintenance costs and downtime.

[0033] 4. In this utility model, the transverse cutting structure and the longitudinal cutting structure are integrated together, making the whole more stable. The longitudinal cutting structure adopts a connection structure that is different from the traditional hinge method, making the operation more stable and the cutting range larger. The two blades of the longitudinal cutting structure can maintain a tight fit for a long time under the action of the compression spring, resulting in a longer service life.

[0040] 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.

[0041] A mechanism for cutting the edges of bound drawings horizontally and vertically includes a fixed frame 9, on which a cutting mounting frame 10 is provided that can slide back and forth along the fixed frame. A horizontal cutting module and a vertical cutting module are provided within the cutting mounting frame. The horizontal cutting module and the vertical cutting module can slide synchronously with the cutting mounting frame, and the vertical cutting module can cut the vertical edge after the horizontal cutting module has cut the horizontal edge.

[0042] A traction module is provided at the rear of the fixing frame, and the traction module uses belt drive or chain drive. Preferably, [the traction module is]... Figure 1 , 2 The belt drive shown includes a driving synchronous pulley 2, a driven synchronous pulley 13, a synchronous belt 6, a sliding block 51, a motor 1, a mounting part 16, and a connecting block 15. The motor is mounted on one end of the fixed frame. Figure 1 The driving synchronous pulley is driven by the output shaft of the motor (a coupling, reducer, or other structure can be used). The driven synchronous pulley is rotatably mounted in the synchronous pulley mounting frame 8 located on the rear surface of the other end of the fixed frame. A synchronous belt is wound around the driving and driven synchronous pulleys. The synchronous belt is fixedly connected to the synchronous pulley at the lower end near the motor. The connecting block is connected to the mounting part located at the upper rear end of the cutting mounting frame. When the synchronous belt moves, it can drive the cutting mounting frame to reciprocate along the guide rail 12 set in the transverse direction of the bottom surface of the fixed frame through the connecting block and the mounting part.

[0043] The above-mentioned cutting and mounting frame is as follows Figure 2 , 3 As shown in Figure 4, the device includes a rear U-shaped plate 20 and a front end plate 25. The upper ends of the two side walls 18 of the U-shaped plate are fixed to the aforementioned mounting portion. A bent section 26 integrally formed on one side wall of the U-shaped plate extends towards the front of the U-shaped plate, and the upper front end of the bent section integrally forms the front panel 30. The lower end of the front end plate is aligned with the front end of the bottom plate of the U-shaped plate, and the upper end of the bent extension of the front end plate integrally forms a frame plate 28. The front side of the frame plate is embedded in the front panel of the U-shaped plate, and the front end plate is provided with multiple openings 39.

[0044] like Figure 2As shown, a cutting and mounting frame position detection sensor module 21 is installed below the U-shaped base plate. When the cutting and mounting frame leaves the mounting frame position detection sensor module, the mounting frame position detection sensor module will generate a departure signal; and when the cutting and mounting frame resets, the mounting frame position detection sensor module will generate a reset signal. These two signals enable the detection of the cutting and mounting frame position.

[0045] The longitudinal cutting module includes a longitudinal moving blade 23 and a longitudinal stationary blade 22. The longitudinal stationary blade is set roughly vertically in the cutting mounting frame below the fixed frame, and its cutting edge is close to or attached to the rear side of the end edge of the stacked pattern that is guided and bent down from above the fixed frame. The longitudinal moving blade is set in the cutting mounting frame in front of the front side of the end edge of the stacked pattern. It can slide back and forth in the front-back direction of the cutting mounting frame. When the longitudinal moving blade and the longitudinal stationary blade are in shearing cooperation, they can cut the end edge of the stacked pattern longitudinally.

[0046] like Figure 4 , 5 As shown, the longitudinal cutting module also includes a slider 44, a longitudinal blade slide rail 17, a swing block 43, a connecting rod 45, and a longitudinal blade mounting plate 24. A longitudinal blade drive motor 19 is installed on one of the two side walls 18 on the rear of the U-shaped plate 20, and a longitudinal blade slide rail that gradually slopes downward from back to front is installed on the other side of the side wall. A slider is slidably installed on the longitudinal blade slide rail, and the slider is connected to the rear end of the longitudinal blade mounting plate. The longitudinal blade mounting plate is located on the side of the upwardly extending bent front end 49 of the cutting mounting frame near the longitudinal stationary blade 22, and a roughly vertical longitudinal blade is installed. The front end of the longitudinal blade mounting plate in front of the slider is hinged to the front end of the connecting rod, the rear end of the connecting rod is hinged to the front end of the swing block, and the rear end of the swing block is connected to the output shaft 42 of the longitudinal blade drive motor.

[0047] The cutting edge of the stationary blade is inclined towards the front of the cutting mounting frame (front panel direction), and the cutting edge of the moving blade is also inclined towards the front of the cutting mounting frame (front panel direction); there is an included angle β between the cutting edges of the stationary blade and the moving blade. Figure 5 (As shown). A preferred solution is an included angle β of 5-10 degrees. A more preferred solution is an included angle β of 7 degrees. The function of this included angle β is that when the longitudinal moving blade moves towards the longitudinal stationary blade, it is equivalent to the lower ends of the two cutting edges contacting each other first, and then gradually moving upwards to contact each other at the upper ends, which is equivalent to the cutting process of scissors.

[0048] A pressure roller 40 is installed on the side of the longitudinal moving blade near the longitudinal stationary blade. When the longitudinal moving blade and the longitudinal stationary blade cut the end edge of the stack A, the pressure roller can press against the clamping plate 41 next to the longitudinal stationary blade to clamp the longitudinally cut paper strip B. After the cutting mounting frame starts to reset, the longitudinally cut paper strip can be torn off from the end edge of the stack A. After the pressure roller resets with the longitudinal moving blade, it separates from the clamping plate, and the torn paper strip falls naturally into the collection box on the ground.

[0049] A trigger plate 47 is provided on the bottom side of the longitudinal blade mounting plate, which is located between the detection components of the longitudinal blade position detection sensor module 46 mounted next to it. When the longitudinal blade mounting plate is displaced, the position of the trigger plate also changes, causing the longitudinal blade position detection sensor module to output different signals, thereby realizing the detection of the longitudinal blade position.

[0050] The upwardly extending bent front end 49 of the longitudinal blade mounting plate is located on the front side of the cutting mounting frame and is connected to the longitudinal blade by two upper and lower fixing bolts 48. The surface of the fixing bolt located between the bent front end and the longitudinal blade is fitted with a longitudinal blade compression spring 50. These two longitudinal blade compression springs can hold the longitudinal blade in place, so that the cutting edge of the longitudinal blade and the cutting edge of the longitudinal stationary blade fit more tightly and can maintain the correct relative position even after long-term operation.

[0051] The cross-cutting module includes a transverse moving blade 29 and a transverse stationary blade 14. The transverse stationary blade is mounted transversely on the bottom surface of the fixed frame, and the transverse moving blade is mounted on the cutting mounting frame above the longitudinal moving blade. Figure 2 As shown, a portion of the cutting edge of the transverse moving blade is located at the bottom surface of the transverse stationary blade, and the upper end surface of this portion of the cutting edge is spaced apart from or attached to the bottom surface of the transverse stationary blade; the transverse moving blade slides synchronously with the cutting mounting frame and performs transverse cutting on the end edge of the stacked image through shearing cooperation with the transverse stationary blade.

[0052] like Figure 3 , 4 As shown in Figure 5, the transverse blade is a circular blade, which is rotatably mounted on the cutting mounting frame above the longitudinal blade. The outer edge of the circular blade is a complete circumference of the cutting edge. A portion of this cutting edge is located at the bottom surface of the transverse stationary blade, and the upper end face of this portion of the cutting edge is spaced apart from or attached to the bottom surface of the transverse stationary blade.

[0053] The specific installation structure of the transverse blade is shown in the figure. A fixing plate 31 is installed on the frame plate 28 at the upper end of the front end plate. A roughly vertical transverse blade mounting post 32 is installed on the fixing plate. The transverse blade mounting post passes through the lower end of the frame plate and, from top to bottom, is fitted with a rotating wheel 33, a circular blade (transverse blade 29), a transverse blade spring 37, and a fixing nut 38. The specific structure and connection relationship are as follows: The rotating wheel uses a rubber wheel, and an upper bearing is embedded in its central through hole. This upper bearing enables the rotating wheel to be supported by the transverse blade mounting post. As the shaft rotates, a lower bearing is installed in the central through hole of the circular blade. This lower bearing allows the circular blade to rotate around the transverse blade mounting post. A gap is maintained between the bottom surface and the upper end surface of the upper bearing. The bottom surface of the rotating wheel is in contact with the upper end surface of the circular blade. The upper end of the transverse blade spring, which is fitted on the transverse blade mounting post below the circular blade, is held in place by a washer or other annular structure against the inner ring (stationary ring, fixed to the transverse blade mounting post). The lower end of the transverse blade spring is limited by a fixing nut screwed onto the lower end of the transverse blade mounting post. The fixing nut is screwed onto the external thread of the lower end of the transverse blade mounting post, and the fixing nut holds the lower end of the transverse blade spring. The upper end of the transverse blade spring, through the lower bearing (holding the stationary ring of the lower bearing), presses the circular blade tightly against the rotating wheel. This achieves a close fit between the upper end surface of the circular blade and the bottom surface of the transverse blade, ensuring accurate transverse cutting.

[0054] An edge detection sensor module 27 for detecting the end of the overlay pattern is installed in the cutting mounting frame next to the transverse blade mounting column (in the transverse cutting direction of the transverse blade). When the transverse blade moves in the cutting direction along with the cutting mounting frame, it starts to accumulate the transverse distance once the end of the overlay pattern is detected, thereby realizing the calculation of the transverse cutting length dimension.

[0055] The transverse cutting blade is mounted on the side of the column (the transverse cutting direction of the transverse cutting blade). Figure 1 A pressure plate wheel 11 is provided on the fixed plate 31 (to the right of the frame). This pressure plate wheel slides with the cutting mounting frame and presses down on the pressure plate 5 located above the front of the fixed frame during sliding. This pressure plate can press down on the end of the stacked pattern that is guided and bent down from above the fixed frame during cutting. The lower bent end 34 of a swing arm 3 is connected to each side of the pressure plate. A pivot (not shown in the figure, labeled 4) is threaded through the upper end of each swing arm. The two pivots are respectively installed on other structures above the fixed frame (not shown in the figure). Figure 3As shown, a wedge-shaped guide block 36 is provided in the cutting mounting frame next to the end of the pressure plate near the motor 1. The most protruding part of the inclined surface 35 of the wedge-shaped guide block facing the front of the cutting mounting frame is roughly flush with the surface of the end of the pressure plate on that side. Moreover, the inclined surface is aligned with the pressure plate wheel on the cutting mounting frame when it is reset. When the cutting mounting frame moves in the transverse cutting direction, the pressure plate wheel moves along the inclined surface of the wedge-shaped guide block and eventually rolls onto the end of the pressure plate on that side. Since the distance between the pressure plate wheel and the fixed frame is fixed, the pressure plate wheel presses the pressure plate towards the fixed frame (the wedge-shaped guide block is fixed, and only the pressure plate swings along the axis of rotation of the two side swing arms towards the fixed frame), thereby pressing the lower end of the stack A above the transverse knife onto the fixed frame.

[0056] The cutting mounting frame position detection sensor module 21, the longitudinal blade position detection sensor module 46, and the edge detection sensor module 27 all use photoelectric sensors as their core, and their data output terminals are all connected to the control module, which collects various position data and outputs control commands.

[0057] The process of using this utility model is as follows:

[0058] In the drawing, the horizontal dotted line at the lower left corner of the overlay A is the position of the horizontal cut edge, and the dashed line on the back is the position of the vertical cut edge. The area B formed by the two is the aforementioned paper strip.

[0059] 1. The cutting and mounting frame is located in the reset position next to the motor. Multiple spaced paper pressing rollers (not shown in the figure) in the paper feeding mechanism (not shown in the figure) above the fixed frame rotate and convey the lower end of the stacked paper A towards the cutting and mounting frame. The guide bending structure (not shown in the figure) in the bending mechanism (not shown in the figure) on the front side of the paper feeding mechanism (not shown in the figure) (approximately above the cutting and mounting frame) bends the lower end of the stacked paper A downward along the guide plate 7 and passes through the gap between the pressing plate and the fixed frame. Finally, the lower end of the bent stacked paper A enters the gap between the longitudinal moving knife and the longitudinal stationary knife.

[0060] The height dimension of the lower end of the stacked diagram A entering between the longitudinal moving knife and the longitudinal stationary knife is identified and confirmed by other mechanisms. These mechanisms are all existing technologies and will not be described in detail here. For example, the internationally accepted 15 mm margin, the domestic A4 paper margin of about 25 mm, and the A2 and A3 paper margin of about 40 mm, etc.

[0061] 2. After completing step 1, the synchronous belt rotates, driving the cutting mounting frame to move in the horizontal cutting direction. The cutting mounting frame position detection sensor module 21 detects that the cutting mounting frame has left the reset position. The edge detection sensor module 27 also moves with the cutting mounting frame. When it detects the left edge of the stacked image A, it outputs the start counting data to the control module. Then, the rearward circular blade and the horizontal stationary blade on the bottom of the fixing frame cooperate to start the horizontal edge cutting. When the length of the horizontal edge cutting reaches the required length, the control module stops the motor 1 and the cutting mounting frame stops. At this time, the edge cutting at the dotted line at the top of the paper strip B is completed.

[0062] 3. The output shaft 42 of the longitudinal blade drive motor 19 rotates and drives the swing block 43 to swing. The swing block drives the rear end of the connecting rod 45 to swing and pull its front end. The front end of the connecting rod drives the longitudinal blade mounting plate 24 and the slider 44 to slide back and forth along the longitudinal blade slide rail 17. The bent front end 49 of the longitudinal blade mounting plate drives the longitudinal blade to move towards the longitudinal stationary blade, completing the cutting edge at the dotted line on the right side of the paper strip B. After the longitudinal blade cuts the edge, a 0.2-0.5 connection is left between the upper right corner of the paper strip and the stacked diagram A. At this time, the swing block 43 that drives the longitudinal blade rotates 180 degrees. The uppermost end of the longitudinal blade and the longitudinal stationary blade are completely in contact. The longitudinal blade position detection sensor module 46 detects that the longitudinal blade has cut in place. The pressure roller 40 and the clamping plate 41 on the longitudinal blade clamp the paper strip B.

[0063] 4. The cutting and mounting frame returns to the position of motor 1. The paper strip B held by the pressure roller and clamping plate is torn off the stacked image A. After the cutting and mounting frame moves a certain distance, the longitudinal blade returns to its original position (the oscillating block rotates 180 degrees again, the longitudinal blade moves away from the longitudinal stationary blade, and the longitudinal blade position detection sensor module 46 detects the longitudinal blade's return). The pressure roller and clamping plate separate, and the paper strip B falls downwards. When the longitudinal blade is fully returned to its original position, the longitudinal blade position detection sensor module detects the return. When the cutting and mounting frame moves to the side of motor 1, the cutting and mounting frame position detection sensor module detects the return.

[0064] 5. Wait for the next cut.
