Description

Technical Field

[0001] This utility model belongs to the field of cutting machine technology, specifically, it relates to an integrated paper picking and feeding mechanism for a cutting machine. Background Technology

[0002] In the cutting and processing of printing, packaging, and other industries, automatic paper picking and delivery are key upstream steps to ensure continuous and efficient production. Traditional cutting equipment generally uses independent paper picking and delivery mechanisms to complete paper transfer: the paper picking mechanism (such as negative pressure adsorption or friction pickup devices) is responsible for separating and picking up individual sheets of paper from the paper storage platform; subsequently, the delivery mechanism (such as guillotine wheels, rollers, or gripping robots) receives the paper and accurately transports it to the cutting table for positioning and cutting. Although this separate design can basically achieve the function, with the increase in production speed and process requirements, its inherent defects have become increasingly prominent, becoming a bottleneck restricting the overall performance improvement of the equipment.

[0003] Specifically, the separate design results in a serial workflow, leading to inefficiency. Because paper picking and delivery are performed sequentially by two independent mechanisms, the equipment must wait for the current paper cutting operation to completely finish before initiating the next picking action after each work cycle. This means that the two mechanisms typically require independent drive, control, and support systems, increasing mechanical complexity and manufacturing costs, and imposing stringent requirements on the precision of motion coordination. In actual operation, paper jams, inaccurate transfers, or damage can easily occur during paper transfer between mechanisms due to timing or positional deviations, affecting operational stability and reliability.

[0004] Therefore, the existing separate design of paper picking and paper delivery mechanisms can hardly meet the urgent needs of modern production for high efficiency, high collaboration and optimized space utilization. There is an urgent need to break through these limitations through integrated innovation. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated paper picking and feeding mechanism for a cutting machine, which solves the technical problem in the prior art where the paper picking and feeding mechanisms are designed separately, resulting in low equipment integration and stringent requirements for the coordination accuracy between the various mechanisms.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An integrated paper feeding and delivery mechanism for a cutting machine includes a cutting machine body, wherein the cutting machine body is provided with a vertically movable paper storage platform and a cutting table for cutting paper. The main body of the cutting machine is equipped with a vertically movable paper picking mechanism above the paper storage platform. A paper feeding mechanism is provided between the cutting table and the paper feeding mechanism, and the paper feeding mechanism and the paper feeding mechanism are connected to each other via a connecting block; A first guide plate is provided above the paper taking mechanism and the paper delivery mechanism, and the first guide plate is connected to the paper taking mechanism. The main body of the cutting machine is fixedly connected with symmetrically arranged adjustment mechanisms.

[0007] The above technical solution further includes: The paper-taking mechanism includes a negative pressure air box, one end of which is equipped with a negative pressure generator; both sides of the negative pressure air box are rotatably connected to a drive shaft via bearing seats; a perforated conveyor belt is rotatably connected to the drive shaft.

[0008] The perforated conveyor belt surrounds the negative pressure air box; an X-axis conveyor motor is installed at the other end of the negative pressure air box.

[0009] The paper feeding mechanism includes a paper feeding worktable; a paper pressing rod is rotatably connected to the upper and lower surfaces of the paper feeding worktable via bearing seats; multiple paper feeding spikes are fixedly connected to the paper pressing rods, and the paper feeding spikes located on the upper and lower surfaces of the paper feeding worktable abut against each other through the paper feeding worktable.

[0010] The paper feeding workbench is fixedly equipped with a paper feeding drive motor at its end, and the paper feeding drive motor drives one of the paper pressing rods through a pulley, causing it to rotate.

[0011] The negative pressure air box is fixedly connected to both ends with lead screw nuts; the adjustment mechanism includes a fixed frame; a ball screw is rotatably connected to the fixed frame, and the ball screw is rotatably connected to the corresponding lead screw nut; the upper part of the ball screw is driven by pulleys and synchronous belts.

[0012] The main body of the cutting machine is equipped with an adjustment drive motor located below the fixed frame, and the adjustment drive motor is driven by a pulley to the lower end of one of the ball screws.

[0013] A second guide plate is fixedly installed at the end of the first guide plate near the cutting table, and the second guide plate is fixedly connected to the main body of the cutting machine.

[0014] This utility model has the following beneficial effects: 1. This utility model integrates the traditionally separate paper picking and paper delivery mechanisms into a single unit, greatly improving the integration of the equipment and enabling the mechanisms to work together. This achieves a tight connection and seamless transition between the paper picking and delivery processes, laying the foundation for subsequent time optimization.

[0015] 2. This utility model, through the integrated design of the paper picking mechanism and the paper delivery mechanism, allows the new work cycle to be carried out synchronously with the current paper cutting process. This parallel working mode effectively "hides" the auxiliary processing time within the main processing time, thereby significantly shortening the total processing cycle of a single sheet of paper.

[0016] 3. Because the first guide plate of this utility model is connected to the paper picking mechanism and the paper delivery mechanism, the first guide plate can follow the paper picking mechanism and the paper delivery mechanism downwards, so as to make room for the paper to return backwards during the paper handling process, avoid positional interference with the paper storage platform, and achieve high space utilization.

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.

[0020] Please see Figure 1 - Figure 2As shown, this utility model proposes an integrated paper feeding and delivery mechanism for a cutting machine, including a cutting machine body 1; a vertically movable paper storage platform 2 is provided inside the cutting machine body 1; a cutting table 6 for cutting paper is provided inside the cutting machine corresponding to the side of the paper storage platform 2; a vertically movable paper feeding mechanism 3 is provided inside the cutting machine body 1 above the paper storage platform 2; a paper delivery mechanism 4 is provided between the cutting table 6 and the paper feeding mechanism 3, and the paper feeding mechanism 3 and the paper delivery mechanism 4 are connected to each other via a connecting block 5; as shown... Figure 5 As shown, a first guide plate 7 is provided above the paper taking mechanism 3 and the paper delivery mechanism 4, and the first guide plate 7 is connected to the paper taking mechanism 3.

[0021] Please refer to it again. Figure 3 As shown, the paper-taking mechanism 3 includes a negative pressure air box 31. A negative pressure generator 35 is installed at one end of the negative pressure air box 31 to provide continuous suction air for the negative pressure air box 31. A drive shaft 32 is rotatably connected to both sides of the negative pressure air box 31 via bearing seats. A perforated conveyor belt 33 is rotatably connected to the drive shaft 32, and the perforated conveyor belt 33 surrounds the negative pressure air box 31. An X-axis conveyor motor 34 is installed at the other end of the negative pressure air box 31, and the X-axis conveyor motor 34 drives the drive shaft 32 to rotate via a pulley.

[0022] Please refer to it again. Figure 3 As shown, the paper feeding mechanism 4 includes a paper feeding worktable 41; paper pressing rods 42 are rotatably connected to the upper and lower surfaces of the paper feeding worktable 41 via bearing seats; multiple paper feeding spikes 43 are fixedly connected to the paper pressing rods 42, and the paper feeding spikes 43 located on the upper and lower surfaces of the paper feeding worktable 41 abut against each other through the paper feeding worktable 41; a paper feeding drive motor 44 is fixedly provided at the end of the paper feeding worktable 41, and the paper feeding drive motor 44 drives one of the paper pressing rods 42 via a pulley, driving it to rotate.

[0023] Please refer to it again. Figure 3 As shown, the paper feeding workbench 41 is connected to the negative pressure air box 31 via the connecting block 5, so that the paper picking mechanism 3 and the paper feeding mechanism 4 are connected to each other.

[0024] Please refer to it again. Figure 4 As shown, the negative pressure air box 31 is fixedly connected to both ends with screw nuts 81; the main body 1 of the cutting machine is fixedly connected with symmetrically arranged adjustment mechanisms 8, which include a fixed frame 82; a ball screw 83 is rotatably connected to the fixed frame 82, and the ball screw 83 is rotatably connected to the corresponding screw nut 81; the upper part of the ball screw 83 is driven by a pulley and a synchronous belt 84; an adjustment drive motor 85 is provided in the main body 1 of the cutting machine corresponding to the lower part of the fixed frame 82, and the adjustment drive motor 85 is driven by a pulley to the lower end of one of the ball screws 83.

[0025] Please refer to it again. Figure 6As shown, a second guide plate 71 is fixedly installed at the end of the first guide plate 7 near the cutting table 6, and the second guide plate 71 is fixedly connected to the main body 1 of the cutting machine.

[0026] In practical applications, this embodiment includes the following steps: Paper collection stage S100, the adjustment mechanism 8 drives the ball screw 83 to rotate by adjusting the drive motor 85, and the ball screw 83 drives the paper picking mechanism 3 to move downward through the screw nut 81; at the same time, the paper storage platform 2 moves upward through the operation of the screw, and the paper position sensor senses the height of the paper on the paper storage platform 2. After reaching the sensing point, the paper storage platform 2 stops moving upward and waits for the adjustment mechanism 8 to drive the paper picking mechanism 3 to move downward to pick up the paper.

[0027] S200 and the negative pressure generator 35 generate suction on the negative pressure air box 31. When the conveyor belt contacts the topmost paper on the paper storage platform 2, the paper is easily adsorbed and grabbed by the perforated conveyor belt 33. After ensuring that only one paper is adsorbed and grabbed, the lifting mechanism indirectly drives the paper delivery mechanism 4 to move to the first height position through the connecting block 5 (e.g., Figure 6 (As shown).

[0028] S300, the X-axis conveyor motor 34 drives the perforated conveyor belt 33 to rotate, causing it to quickly move the paper to the pressure cutting table 6. When the paper extends a certain length from the front end, the paper front end is slightly bent due to the suspension of the paper front end. At this time, the paper front end is just close to the paper feeding guillotine wheel 43. The X-axis conveyor motor 34 will convey the paper between the upper and lower paper feeding guillotine wheels 43. The paper feeding drive motor 44 will receive the paper through the paper pressing rod 42 and the paper feeding guillotine wheel 43.

[0029] Paper delivery stage S400. Since the upper and lower paper feeding pins 43 of the paper feeding mechanism 4 are at the same height as the pressure cutting table 6, if the cutting process of the previous paper on the pressure cutting table 6 has not been completed, the paper feeder waits in place under the action of the paper feeding drive motor 44 until the cutting of the previous paper is completed, and then the paper feeder is conveyed to the pressure cutting table 6 under the guidance of the second guide plate 71; if the cutting process of the previous paper on the pressure cutting table 6 has been completed, the paper feeding drive motor 44 will directly convey the paper feeder to the pressure cutting table 6.

[0030] Paper handling process S500, the upper and lower pressure rollers on the pressure cutting table 6 quickly receive the paper being fed by the paper feeding mechanism 4. At this time, under the fixed operating procedure of the system, the camera simultaneously performs two operations: determining the position of the paper being fed and reading the QR code information of the paper being fed.

[0031] S600 After the system determines the paper feeding position and the cutting program carried by the QR code information, the carriage beam system of the cutting machine performs full-width operation (referring to the paper feeding and unloading process of full-width paper) through the upper and lower paper pressing rollers on the cutting table 6.

[0032] To prevent the paper-taking mechanism 3 from interfering with the movement path of the paper during the paper handling process, this embodiment indirectly drives the paper-feeding spike wheel 43 downward by adjusting the drive motor 85 in conjunction with the connecting block 5, moving it to the second height position (e.g., Figure 6 As shown, the end of the first guide plate 7 is aligned with the height of the pressure cutting table 6, so that it can unfold towards the first guide plate 7 when the paper is being handled and returned, thus providing a return path for the paper.

[0033] S700 After the paper handling is completed, the trolley beam system cuts the ends of the paper through the cutting trolley. The paper unfolded on the first guide plate 7 gradually moves towards the pressure cutting table 6 until the cutting is completed. At the same time, the paper picking mechanism 3, the paper delivery mechanism 4, and the paper storage platform 2 carry out a new round of operations simultaneously during the cutting process.

[0034] It is worth noting here that since the first guide plate 7, the paper picking mechanism 3, and the paper delivery mechanism 4 are not directly connected, the downward operation of the paper picking mechanism 3 and the paper delivery mechanism 4 does not affect the unfolding and movement of the first guide plate 7.

[0035] The integrated paper picking and feeding mechanism for a cutting machine provided by this utility model greatly improves the integration of the equipment by integrating the traditionally independent paper picking mechanism 3 and paper feeding mechanism 4 into a complete unit. The mechanisms can work together to achieve a tight connection and seamless transition of the paper picking and feeding process, laying the foundation for subsequent time optimization.

[0036] This invention provides an integrated paper picking and feeding mechanism for a cutting machine, which changes the traditional serial mode where the next work cycle cannot begin until the entire cutting (press-cutting) process is completed. Through the integrated design of the paper picking mechanism 3 and the paper feeding mechanism 4, the new work cycle (the processes of paper picking, paper feeding, and the paper storage platform 2) can be performed synchronously with the current paper cutting process. This parallel working mode effectively "hides" auxiliary processing time within the main processing time, thereby significantly shortening the total processing cycle for a single sheet of paper.

[0037] The integrated paper picking and feeding mechanism for a cutting machine provided by this utility model has a first guide plate 7 connected to the paper picking mechanism 3 and the paper feeding mechanism 4. Therefore, when the paper picking mechanism 3 and the paper feeding mechanism 4 move downward, the first guide plate 7 can follow and move downward, making room for the paper to return backward during the paper handling process, avoiding positional interference with the paper storage platform 2, and achieving high space utilization.
