Description

Technical Field

[0001] This utility model relates to the technical field of paper cutting equipment for printing, and in particular to a paper cutting device for printing samples. Background Technology

[0002] In the printing production process, to improve production efficiency, multiple products are usually produced on a single sheet of printing plates. To control printing quality, frequent sampling and inspection of printed samples are necessary during production to control aspects such as image quality, defects, color difference, smoothness, and abrasion resistance. Simultaneously, to ensure consistency in quality across all printed products on the same sheet, standardized cutting processes are implemented on the sampled sheets according to printing quality inspection standards. This involves cutting a large sheet into several smaller prints as needed, facilitating targeted inspections of critical quality areas such as color variations, color bleeding, and smoothness.

[0003] Currently, the cutting of printed sheets for random inspection mainly relies on manual paper cutters. While this method is flexible, it lacks precision, and each printed product on the sheet needs to be trimmed, which greatly reduces inspection efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a printing sample cutting device that can cut printing samples into multiple sheets at one time, thereby improving cutting efficiency.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: A printing sample cutting device includes a cutting platform, a suction assembly, and a cutting blade assembly. The cutting blade assembly is slidably and swingably disposed on the cutting platform. The suction assembly is connected to the cutting platform. During cutting, the suction assembly opens to fix the paper, and the cutting blade assembly swings to the cutting position to make it contact the paper and slides to cut the paper into at least two pieces.

[0006] The printing sample cutting device further includes a locking component for locking the cutting blade assembly, the locking component being disposed at one end or one side of the cutting platform.

[0007] In the aforementioned printing sample cutting device, the cutting blade assembly includes at least one blade, a blade holder, and a blade shank. The blade is disposed on the blade shank, and both ends of the blade shank are fixed to the blade holder.

Sample sheet Detailed Implementation 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. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] It should be noted that when a component is referred to as being "mounted on," "fixed to," or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0022] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of this utility model are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0023] Please see Figure 1 , Figure 2 and Figure 3 The printing sample cutting device provided by this utility model includes a cutting platform 1, a suction component (not shown in the figure) and a cutting blade component 2. The cutting blade component 2 is slidably and swingably disposed on the cutting platform 1. The suction component is connected to the cutting platform 1 and can adsorb the paper on the cutting platform 1 when the suction component is activated, preventing the paper from moving during the cutting process.

[0024] During cutting, the suction assembly activates to fix the paper (i.e., sample 100), and the cutting blade assembly 2 swings to the cutting position to contact the paper, then slides to cut the paper into at least two pieces. Specifically, during the cutting process, the cutting platform 1 provides a stable reference surface for cutting, and the suction assembly ensures that the paper receives uniform suction force, effectively preventing the paper from moving during cutting. Then, the cutting blade assembly 2 is swung to the cutting position (e.g., sample 100). Figure 1From the perspective of the cutting assembly 2, the blade of the cutting assembly 2 swings upward, so that the blade of the cutting assembly 2 is in the cutting position, so that the blade contacts the paper, and then the paper is cut into at least two pieces by sliding action. This design not only improves the cutting flexibility, but also enables multiple pieces of paper to be cut at once, which greatly improves production efficiency.

[0025] The cutting assembly 2 includes at least one blade 20, a blade holder 21, and a blade shank 22. The blade 20 is mounted on the blade shank 22, and both ends of the blade shank 22 are fixed to the blade holder 21. When the cutting assembly 2 swings to the cutting position, the blade 20 can be operated to cut by pushing the blade holder 21. To further improve the convenience of operation, a handle 23 is provided on the blade holder 21. During the cutting process, the operator only needs to hold the handle 23 to freely swing and push the blade holder 21, making the cutting process simple and efficient.

[0026] Of course, the printing sample cutting device of this utility model not only supports manual control of the swing and movement of the blade holder 21 via the handle 23, but also possesses high flexibility and expandability. For example, the swing and movement of the blade holder 21 can be automatically controlled using automated structures such as robotic arms, motors, or cylinders. This automated control method can further improve cutting efficiency and is particularly suitable for large-scale production. The specific implementation method can be selected according to actual needs and is not limited here.

[0027] Please continue reading. Figure 1 and Figure 3 The bottom of the blade holder 21 is provided with a slider 24, and the two sides of the cutting platform 1 have sliding grooves 11. The slider 24 is set in the sliding grooves 11. Through the cooperation of the slider 24 and the sliding grooves 11, the blade holder 21 can move smoothly from the sliding grooves 11, effectively avoiding the problem of uneven paper cutting edges caused by jamming during the cutting process.

[0028] Furthermore, the bottom of the blade holder 21 is connected to the slider 24 via a pivot 25. A first spring 26 is also provided at the bottom of the blade holder 21, with one end abutting against one side of the blade holder 21 and the other end abutting against the slider 24. During cutting, holding the handle 23 allows the blade holder 21 to swing around the slider 24 as a fulcrum, facilitating cutting. When the blade holder 21 swings to the height of the cutting platform 1, the first spring 26 is compressed, providing resistance to the cutting and preventing the operator from damaging the blade 20 by applying excessive force. After releasing the handle 23, the blade holder 21 quickly returns to an upright position using the spring's restoring force.

[0029] Specifically, the lower part of the blade holder 21 has a recess (not labeled in the figure) that engages with the cutting platform 1 when it is upright. When the blade holder 21 is in an upright state, it is shaped like a "7", with the upper part being larger and the lower part being smaller, forming a "top-heavy" structure. This makes it easier and less strenuous for the operator to swing the blade holder 21 using the handle 23, greatly improving the convenience and efficiency of cutting.

[0030] Preferably, the design of the cutting blade assembly 2 not only considers the practicality of cutting but also takes into account the precision of operation. In addition to the basic blade 20, blade holder 21, and blade shank 22, it is also specially equipped with a blade retainer 27 and a scale 28. The scale 28 is mounted on the blade shank 22, and the blade 20 is detachably mounted on the blade retainer 27. For example, the blade 20 can be fixed to the blade retainer 27 with screws to prevent the blade 20 from moving during cutting. The blade retainer 27 is provided with a locking fastener 271 (such as a bolt), which can adjust the tightness between the blade retainer 27 and the blade shank 22 by adjusting the screw-in state of the locking fastener 271, allowing the blade retainer 27 to move along the blade shank 22, thereby adjusting the cutting position of the blade shank 22. In this invention, the detachable mounting method of the blade 20 and the blade retainer 27 makes the replacement of the blade 20 and the adjustment of the cutting position extremely convenient.

[0031] Before cutting, the operator can adjust the cutting position of the blade 20 and the spacing between adjacent blades by moving the blade holder 27 to ensure that the cutting edge of the blade 20 is precisely aligned with the cutting line of the paper, thereby achieving precise cutting. The auxiliary function of the scale 28 makes this adjustment process more intuitive and accurate, even for beginners, ensuring that every cut achieves the desired effect. Specifically, the blade holder 27 may also be provided with dotted or solid lines. When installing the blade 20, align the blade edge of the blade 20 with the dotted line (not labeled in the figure) or solid line to facilitate aligning the blade edge of the blade 20 with the cutting line on the paper when adjusting the blade holder 27.

[0032] The scale 28 is located at the blade fixing member 27, allowing the operator to visually observe the specific distance that each blade fixing member 27 can be adjusted. During pre-cutting preparation, the operator can easily and precisely adjust the position of the blade 20 using the scale 28, ensuring that each cut achieves ideal precision. This intuitive visual assistance not only improves cutting accuracy but also greatly enhances operational convenience and efficiency, making the cutting process more intuitive and efficient.

[0033] Please refer to the following: Figure 4The printing sample cutting device also includes a locking component 3 for locking the cutting blade assembly 2. The locking component 3 is located at one end or one side of the cutting platform 1. The locking component 3 can lock the cutting blade assembly 2 when it is idle, effectively avoiding the risk of misoperation.

[0034] The locking assembly 3 includes a knob 31, a latch 32, a second spring 33, a locking hook 34, and a control component 35. The locking hook 34 is connected to the latch 32, the second spring 33 is sleeved on the latch 32, and the knob 31 is connected to the control component 35. The bottom of the tool holder 21 has a latch hole 29 for inserting the front end of the latch 32. In the locked state, the front end of the latch 32 is inserted into the latch hole 29, thus fixing the tool holder 21 and preventing it from being accidentally unfolded. When it is necessary to unfold the tool holder 21, simply turn the knob 31 gently to return the locking hook 34 to its original position, and the latch 32 will retract, allowing the tool holder 21 to unfold smoothly. After unfolding, thanks to the elasticity of the second spring 33, the latch 32 can automatically reset. The entire process is simple to operate and very convenient to use. Since the specific structure and locking method of the locking assembly 3 are existing technologies, they will not be described in detail here.

[0035] like Figure 1 As shown, the cutting platform 1 has a recess 12 for accommodating the knob 31, so that the knob 31 is not exposed outside the cutting platform 1, effectively avoiding the risk of the knife holder 21 accidentally popping open due to misoperation, and enhancing the safety of the printing sample cutting device.

[0036] The cutting platform 1 is provided with a blade groove 13 at the starting end of the slide 11 to accommodate the blade shank 22 and the blade 20. In the initial state, the latch 32 is inserted into the latch hole 29 at the bottom of the blade holder 21, so that the blade holder 21 is kept in a downward tilted state (e.g., Figure 1 From the perspective of the downward tilt (even when the tool holder 21 is in a laid-down state), the blade 20 and the tool holder 22 are placed in the tool holder groove 13, which not only provides safe protection for the blade 20, but also avoids accidental damage to the blade 20 when it is idle.

[0037] When the blade holder 22 is placed in the blade holder groove 13, the blade fixing member 27 abuts against the cutting platform 1 and is partially exposed on the cutting platform 1. When the paper is placed on the cutting platform 1, one end of the paper abuts against the blade fixing member 27, which not only helps to align the paper and ensure the accuracy of cutting, but also makes it easier for the operator to align the blade 20 with the cutting line on the paper, thereby achieving efficient and accurate cutting operations.

[0038] The cutting platform 1 is provided with a plurality of ventilation holes 14 evenly distributed on it. The suction assembly is connected to the ventilation holes 14, which are evenly distributed on the cutting platform 1. During the cutting process, the suction assembly generates a uniform negative pressure through these ventilation holes 14, firmly adhering the paper to the cutting platform 1. The evenly distributed design ensures that the paper is subjected to uniform force during cutting, effectively preventing paper displacement during the cutting process, thereby improving the accuracy and quality of cutting. Since the structure and principle of the suction assembly are common methods for fixing paper, they will not be described in detail here.

[0039] Furthermore, the bottom of the cutting platform 1 is also provided with an anti-slip pad 15, which can effectively prevent the risk of uneven cutting or the printing sample cutting device falling due to the movement of the cutting blade assembly 2 during the cutting process.

[0040] To make the structure and operation process of the printing sample cutting device of this utility model clearer, the following describes the operation method in detail using the cutting of 100 printing samples as an example: 1. Place sample 100: Lay the sample 100 to be tested flat on the cutting platform 1, ensuring that the gripper edge of the sample 100 is aligned with the closed blade holder 27. Then turn on the suction assembly to use negative pressure to firmly fix the sample 100 to the cutting platform 1 and prevent the paper from shifting during cutting.

[0041] 2. Adjust the position of blade 20: Based on the cutting line on the printed sample 100, flexibly adjust the position of the blade fixing part 27 until the dotted or solid line on the blade fixing part 27 is precisely aligned with the cutting line. At this time, the cutting edge of blade 20 is also aligned with the cutting line, ready for precise cutting. Of course, depending on the width or length of the cut sample, you can first adjust the cutting position of blade 20, then place the sample and align the cutting line on the printed sample 100 with the cutting edge of the blade.

[0042] 3. Cutting operation: Gently turn knob 31 to unlock and open the closed blade holder 21. At this time, the blade holder 21 can be swung upwards to the cutting angle (e.g., Figure 1 As shown, the blade holder 21 is at an upright angle. Then, hold the handle 23 to tilt the blade holder 21 slightly, allowing the blade 20 to gently contact the printed sample 100. Subsequently, move the blade holder 21 smoothly to cut the sample 100 along the predetermined cutting line.

[0043] 4. Repeated cutting: After one cutting is completed, the paper direction can be adjusted as needed, and the above cutting steps can be repeated multiple times to meet different testing requirements.

[0044] 5. Finishing steps: After cutting, reset and close the blade holder 21, locking it with the locking component 3. Turn off the suction component, collect and organize the cut samples, and you can proceed to the next testing step.

[0045] In summary, the printing sample cutting device provided by this utility model includes a cutting platform, a suction assembly, and a cutting blade assembly. The cutting blade assembly is slidably and swingably mounted on the cutting platform. The suction assembly is connected to the cutting platform. During cutting, the suction assembly opens and fixes the paper, and the cutting blade assembly swings to the cutting position to contact the paper, then slides to cut the paper into at least two pieces. Specifically, during the cutting process, the cutting platform provides a stable reference surface for cutting. The suction assembly ensures that the paper receives uniform suction force, effectively preventing the paper from moving during cutting. The cutting blade assembly is then swinged to the cutting position so that its blade contacts the paper, and then the paper is cut into at least two pieces through a sliding motion. This design not only improves the flexibility of cutting but also enables multiple pieces of paper to be cut at once, greatly improving production efficiency.

[0046] Furthermore, this invention features a simple structure and easy operation. The adjustable blade fixing component and the safety features of the locking assembly further optimize the user experience, resulting in high practicality and reliability in real-world applications.
