Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper cutting technology, specifically an adjustable printing paper cutting machine. Background Technology
[0002] In industries such as printing and packaging, paper cutters are essential processing equipment used to cut rolls of paper or single sheets into the required sizes. Traditional paper cutters typically employ a fixed blade holder structure, achieving cutting through mechanical transmission or hydraulic drive.
[0003] An existing patent (authorization announcement number: CN222537740U) discloses an adjustable paper cutting device for printing processing. The key technical points of this device are: the output end of a cylinder moves downwards, causing a connecting plate to move downwards. A lifting block, driven by the connecting plate, slides downwards on the outside of a sliding rod. The lifting block and sliding rod prevent the cutting blade from wobbling during the cutting process. The connecting plate drives a support plate downwards, which in turn drives a connecting rod and a support column downwards. The bottom of the pressing plate contacts the top of the paper being cut. As the output end of the cylinder continues to move downwards, the connecting rod enters the interior of the support column. The slider slides downwards inside the support column, compressing a first spring. Under the tension of the first spring, the pressing plate continuously presses down on the paper to be cut. Under the action of the pressing mechanism, before the cutting blade cuts the paper, the pressing plate can press the paper on both sides of the cutting blade firmly, preventing the paper from bulging due to uneven force and avoiding slight paper deviation, thus ensuring cutting accuracy.
[0004] However, the above technical solutions still have certain defects. Paper scraps and dust are easily generated during the paper cutting process. Accumulation in the cutting area will affect the blade life and cutting quality. At the same time, the cleaning intensity of the paper cannot be adjusted during cleaning, which can easily cause paper damage or inadequate cleaning of the paper surface. Therefore, an adjustable printing paper cutting machine is proposed. Utility Model Content
[0005] The purpose of this invention is to provide an adjustable printing paper cutting machine to solve the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An adjustable printing paper cutting machine includes a frame, an unwinding roller fixedly disposed on one side of the frame, a winding assembly disposed on the other side of the frame, a cleaning assembly for cleaning the paper fixedly disposed on the frame, and a cutting assembly for cutting the paper also disposed on the frame.
[0008] The cutting assembly includes a fixed plate fixedly mounted on a frame, a driven plate rotatably mounted on one side of the fixed plate, three sets of rotating rollers rotatably mounted on the driven plate, a fixed rod rotatably mounted on the top of the fixed plate, multiple sets of cutters mounted on the fixed rod, and an adjustment assembly mounted on the side of the fixed plate away from the driven plate.

[0010] Based on the above technical solutions, this utility model also provides the following optional technical solutions:
[0011] As a further embodiment of this utility model: the adjustment assembly includes a rotating handle rotatably mounted on the fixed plate on the side away from the driven plate. A driven shaft is fixedly mounted at the end of the rotating handle. The driven shaft is fixedly connected to the driven plate.

Multiple sets of springs are provided at the bottom of the inner wall of the mounting base. Two sets of limiting blocks are provided at the top of the springs. A sliding block is provided through the two sets of limiting blocks. A groove is provided on the mounting base to facilitate the sliding of the sliding block.
[0012] As a further improvement of this utility model: the spacing between the two sets of limiting blocks is equal to the width of the extension strip, the limiting blocks slide within the mounting base, and the top corners of the limiting blocks are rounded.

[0017] As a further improvement of this utility model, the take-up roller is made of silicone material.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. This utility model, by setting an adjustment component, drives the driven shaft to rotate by rotating the rotating handle, and the driven shaft drives the extension strip to rotate. When the extension strip rotates past the limit block, the spring pushes the limit block to reset. The limit block and the extension strip make lateral contact to form a self-locking mechanism. By driving the rotating roller to rotate, the height of the paper is adjusted, thereby adjusting the distance between the paper and the air blowing pipe to prevent paper damage or inadequate cleaning.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0034] In one embodiment, such as Figures 1-6 As shown, an adjustable printing paper cutting machine includes a frame 2, an unwinding roller 1 fixedly disposed on one side of the frame 2, a winding assembly 5 disposed on the other side of the frame 2, a cleaning assembly 3 for cleaning the paper fixedly disposed on the frame 2, and a cutting assembly 4 for cutting the paper also disposed on the frame 2.
[0035] In this embodiment, the unwinding roller 1 carries the roll of paper or continuous paper to be cut. The paper is smoothly conveyed to the cutting area under tension control. At the same time, the winding assembly 5 is responsible for pulling the paper and winding the cut finished product to ensure that the paper runs stably during the cutting process. Before the paper enters the cutting area, the cleaning assembly 3 blows the paper surface to remove paper scraps, dust and other impurities to prevent them from affecting the cutting accuracy or damaging the blade. The cutting assembly 4 cuts the paper surface to make the paper into multiple strips.
[0036] In one embodiment, such as Figure 2As shown, the take-up assembly 5 includes a drive motor 51 fixedly mounted on the side of the frame 2 away from the unwinding roller 1. A gear 52 is fixedly mounted on the output end of the drive motor 51. The gear 52 is connected to a first driven roller and a second driven roller via a toothed belt. A driven roller 53 and a take-up roller 54 are fixedly connected to the central axis of the first and second driven rollers. The central axes of the driven roller 53 and the take-up roller 54 are on the same vertical plane, and the diameter of the driven roller 53 is larger than that of the take-up roller 54. The take-up roller 54 is made of silicone material. The drive motor 51 serves as a power source, and its output end is connected to the gear 52, which drives the gear 51 via a toothed belt. Power is transmitted to the first driven roller and the second driven roller. The central shaft of the first driven roller is connected to the driven roller 53, which is mainly used to assist in traction of the paper and ensure that the paper remains flat before entering the take-up roller 54. The central shaft of the second driven roller is connected to the take-up roller 54, which is directly responsible for winding up the cut paper. Since the diameter of the driven roller 53 is larger than that of the take-up roller 54, the linear speed of the driven roller 53 is slightly faster than that of the take-up roller 54, so that the paper maintains appropriate tension before winding and prevents loosening or wrinkling. At the same time, the take-up roller 54 is made of silicone material, whose high coefficient of friction and elasticity can effectively prevent the paper from slipping and avoid paper indentations or damage that may be caused by hard roller surfaces.
[0037] In one embodiment, such as Figure 3 As shown, the cleaning component 3 includes a mounting bracket 31 fixedly installed on the top of the frame 2. An air pump 32 is fixedly installed on the mounting bracket 31. The air pump 32 is connected to an air collection pipe 33. Multiple sets of air blowing pipes 34 are fixedly installed at the bottom of the air collection pipe 33. The air blowing pipes 34 are connected to the air collection pipe 33. The high-pressure airflow output by the air pump 32 is collected and distributed through the air collection pipe 33. The air collection pipe 33 serves as a transfer hub for the airflow, ensuring uniform airflow distribution. The multiple sets of air blowing pipes 34 connected to the bottom of the air collection pipe 33 precisely guide the high-pressure airflow to the paper surface, forming a continuous blowing force. When the paper passes through the cleaning area, the high-speed airflow ejected by the air blowing pipes 34 effectively removes dust, paper scraps and other impurities from the paper surface.
[0038] In one embodiment, such as Figure 4 As shown, the cutting assembly 4 includes a fixed plate 41 fixedly mounted on the frame 2. A driven plate 42 is rotatably mounted on one side of the fixed plate 41. Three sets of rotating rollers 43 are rotatably mounted on the driven plate 42. A fixed rod 44 is also rotatably mounted on the top of the fixed plate 41. Multiple sets of cutters 45 are mounted on the fixed rod 44. An adjustment assembly 46 is also provided on the side of the fixed plate 41 away from the driven plate 42. The three sets of rotating rollers 43 are distributed on the driven plate 42 to form a stable paper conveying plane. The driven plate 42 and the fixed plate 41 form a rotating pair. By rotating the driven plate 42, the three sets of rotating rollers 43 rotate to adjust the tension of the paper. When the paper passes through the cutting assembly 4, it is cut by the multiple sets of cutters 45.
[0039] As a supplement: the cutter 45 consists of a fixing block 451 and a cutting blade 452; the fixing blocks 451 are arranged in an array on the fixing rod 44, and the ends of the fixing blocks 451 are provided with limiting heads to limit the cutting blade 452, and the middle of the cutting blade 452 is provided with three sets of circular holes corresponding to the limiting heads; the fixing blocks 451 are made of high-strength aluminum alloy, and form a transition fit with the limiting heads through the three sets of positioning circular holes. The blade is installed by aligning with the limiting heads through the circular holes, so that the blade can be installed at any of the three sets of positioning circular holes. By adjusting the position of the circular hole where the blade is located, the paper is cut. By different blade positions, different parts of the corresponding blades can be adjusted for paper of different hardness to achieve the best cutting position.
[0040] In one embodiment, such as Figure 5 and Figure 6 As shown, the adjusting assembly 46 includes a rotating handle 461 rotatably mounted on a fixed plate 41 on the side away from the driven plate 42. A driven shaft 462 is fixedly mounted at the end of the rotating handle 461. The driven shaft 462 is fixedly connected to the driven plate 42. Multiple sets of extension strips 463 are arranged in a circular array around the center of the driven shaft 462. A mounting base 464 is also provided at the bottom of the fixed plate 41. Multiple sets of springs 465 are provided at the bottom of the inner wall of the mounting base 464. Two sets of limiting blocks 466 are provided at the top of the springs 465. A sliding block 467 is provided through the two sets of limiting blocks 466. A groove is provided on the mounting base 464 to facilitate the sliding of the sliding block 467. By rotating the rotating handle 461, the driven shaft 462 is driven. The driven shaft 462 rotates, causing the extension bar 463 to rotate. When the extension bar 463 rotates past the limit block 466, the spring 465 pushes the limit block 466 to reset. The limit block 466 and the extension bar 463 make lateral contact to form a self-locking mechanism. When unlocking is required, the sliding block 467 is pressed down, causing the limit block 466 to move downward along the side wall of the mounting base 464, thus completing the unlocking. Continuing to rotate the driven shaft 462 can be used to adjust the angle between the driven plate 42 and the fixed plate 41, causing the rotating roller 43 to rotate and adjusting the height of the paper, thereby adjusting the distance between the paper and the air pipe 34. Rotating the rotating handle clockwise moves the paper away from the air pipe 34 to prevent paper damage, while rotating the rotating handle counterclockwise moves the paper closer to the air pipe 34 to prevent inadequate cleaning of the paper surface.
[0041] In one embodiment, such as Figure 6As shown, the spacing between the two sets of limiting blocks 466 is equal to the width of the extension strip 463. The limiting blocks 466 slide within the mounting base 464, and the top corners of the limiting blocks 466 are rounded. The cleaning component 3 is located diagonally above the cutting component 4. The spacing between the limiting blocks 466 and the width of the extension strip 463 form a precise transition fit. At the same time, the top corners of the limiting blocks 466 are rounded to ensure that the extension strip 463 can accurately engage between the limiting blocks 466 each time it is positioned. The diagonal upward arrangement allows the blowing airflow to form the optimal impact angle with the paper, ensuring that the cleaning range is maximized.
[0042] The above embodiment discloses an adjustable printing paper cutting machine, wherein a motor drive is responsible for pulling the paper and winding the cut finished product to ensure that the paper maintains stable operation during the cutting process. Before the paper enters the cutting area, the air pump 32 drives the air pipe 34 to blow the paper surface to remove paper scraps, dust and other impurities, preventing them from affecting the cutting accuracy or damaging the blade. At the same time, the fixed plate 41 serves as a support structure, on which a rotatable fixed rod 44 is installed. When the paper passes through the cutting component 4, the cutter 45 cuts the paper, and the tension of the paper and the distance between the paper and the air pipe 34 are adjusted by rotating the angle of the three sets of rotating rollers 43 to prevent the paper from breaking and to prevent the paper from being not cleaned properly.
[0043] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
