A telescopic auxiliary tool for slitting a grating printed piece

Abstract

This utility model belongs to the field of lenticular printing processing technology and discloses a telescopic lenticular printing slitting auxiliary tool to solve the problems of difficult and error-prone manual lenticular card slitting and positioning. It includes two sets of parallel limiting strips, telescopic push blocks, telescopic rods, handles, and a fixed-distance extension component. The fixed-distance extension component includes two types of staggered fixed-distance stops and a movable stop fixed on the telescopic rod. It is also equipped with auxiliary structures such as a vertical structural plate, a telescopic rod support plate, an anti-detachment structural component, and an anti-tilting cover. In use, the large sample is pressed against the telescopic push block, and the telescopic rod is pushed to move the sample towards the slitting cutter. When the movable stop is pressed against the fixed-distance stop, the sample extends beyond the single-plate size, and can be slitting. Rotating the movable stop changes the posture to press against another type of fixed-distance stop, and the reciprocating operation completes continuous slitting. This tool does not require a ruler, avoids positioning errors caused by visual interference from lenticular patterns, and improves slitting efficiency and accuracy. It is suitable for lenticular printing sample slitting.

Description

Technical Field

[0001] This utility model relates to the field of lenticular printing processing technology, specifically a telescopic lenticular printing cutting auxiliary tool. Background Technology

[0002] In the field of card printing production, slitting is a key step in finished product processing, and its technological maturity has reached a level that meets the needs of large-scale mass production. Currently, large-scale automated slitting equipment, with its advantages of high efficiency and precision, is widely used in the batch slitting of standardized card printing parts. It can quickly cut regular cards, and the slitting size error is controlled within a very small range, effectively ensuring production efficiency and product quality in the mass production stage. However, the situation is quite different in the prototyping stage of card production. The core requirement of the prototyping stage is to quickly verify the design scheme, ink compatibility, and printing effect. Usually, only a small number of samples need to be made, without large-scale production. At this time, if large-scale slitting equipment is used, it not only requires complex equipment debugging and parameter settings, but also consumes a certain amount of preparation time and cost. The operation process is cumbersome and lacks flexibility, making it difficult to adapt to the small-batch, multi-batch, and fast-turnaround operation characteristics of the prototyping stage. Therefore, in the prototyping stage, the industry still generally uses manual slitting to complete the cutting of lenticular card printing parts. Although this method can meet the flexibility requirements of prototyping, it faces many unavoidable technical pain points. Among these challenges, the manual slitting of lenticular card printing presents a particularly prominent problem. This issue stems from the unique physical properties of lenticular cards themselves. Unlike regular cards, lenticular cards are covered with a lenticular layer, and their internal microstructures cause the patterns on the card to exhibit dynamic changes as the viewing angle changes, such as pattern displacement, deformation, and color transitions. This dynamic visual characteristic poses a significant challenge to the positioning process in manual slitting. During the manual slitting process, to ensure that the dimensions of the lenticular cards meet design standards, operators must use a ruler to precisely measure and position the cards. Due to the dynamic changing nature of the lenticular card patterns, operators cannot quickly align and position them using a fixed pattern reference as they would with regular cards; they must rely on the scale on the ruler for measurement. However, in practice, operators need to simultaneously focus on the fine scale on the ruler and the dynamically changing lenticular patterns for extended periods, and the superposition of these two visual information can easily cause eye strain. As the work time increases, operators' eye muscles remain under constant tension, easily leading to blurred vision and other visual disturbances. This visual fatigue directly results in a significant decrease in measurement and positioning accuracy, frequently causing errors in scale reading and positioning reference misalignment. The dynamic changes in the grating pattern also make it difficult to accurately determine whether the positioning lines perfectly coincide with the cutting lines. These positioning errors directly cause the grating cards to exceed size limits after cutting. Some samples cannot be used for proofing verification due to excessive dimensional deviations, wasting printing materials, extending the proofing cycle, increasing proofing costs, and negatively impacting subsequent design verification and customer confirmation processes. This severely restricts the efficiency and quality stability of the grating card printing proofing process. Utility Model Content

[0014] 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.

[0015] Please see Figure 1-4 This utility model provides a technical solution: A telescopic lenticular printing slitting auxiliary tool includes a cutting plate 1, a slitting cutter 2 on one side of the cutting plate 1, and further includes: Two sets of limiting strips 3 are fixedly set on the cutting plate 1. The two sets of limiting strips 3 are parallel to each other, and the two sets of limiting strips 3 form a limiting groove corresponding to the large plate sample. Telescopic push block 4 is set between two sets of limit bars 3, and the cutting plate 1 can move forward and backward relative to the cutting guillotine 2. Telescopic rod 5 is located on the side of telescopic push block 4 away from slitting cutter 2, and a handle 6 is provided at the end of telescopic rod 5; The fixed-distance extension component 7 is located on the outside of the limiting strip 3. The fixed-distance extension component 7 includes multiple sets of first fixed-distance stops 8, multiple sets of second fixed-distance stops 9, and movable stops 10. The first fixed-distance stops 8 and the second fixed-distance stops 9 are arranged alternately and fixedly, and the movable stops 10 are fixedly mounted on the telescopic rod 5.

[0016] Furthermore, the first fixed-distance stop 8 is fixedly mounted on the cutting plate 1, and the first fixed-distance stop 8 is perpendicular to the cutting plate 1. The height of the first fixed-distance stop 8 is higher than the height of the movable stop 10 facing the first fixed-distance stop 8.

[0017] Furthermore, a vertical structural plate 11 is provided on the outer side of the cutting plate 1 near the first fixed-distance stop 8. The vertical structural plate 11 is perpendicular to the cutting plate 1. The second fixed-distance stop 9 is fixedly provided on the side of the vertical structural plate 11 near the first fixed-distance stop 8. The second fixed-distance stop 9 is perpendicular to the vertical structural plate 11. The height of the second fixed-distance stop 9 is higher than the height of the movable stop 10 facing the side of the second fixed-distance stop 9. The first fixed-distance stop 8 and the second fixed-distance stop 9 are staggered. In use, the large sample to be cut is placed between the slitting guillotine 2 and the telescopic pusher 4, and the sample is pressed against the telescopic pusher 4. The operator holds the handle 6 and pushes the telescopic rod 5 to one side of the slitting guillotine 2. Due to the presence of the movable stop 10, when the movable stop 10 presses against a set of the first fixed-distance stops 8, the sample extends a fixed distance. The sample can be pressed down for cutting. After cutting, the movable stop 10 is rotated (to the position corresponding to the second fixed-distance stop 9) and the telescopic rod 5 is pushed to one side of the slitting guillotine 2. At this time, the movable stop 10 presses against the second fixed-distance stop 9, and the sample extends a fixed distance again. Then the movable stop 10 is rotated again (to the position corresponding to the first fixed-distance stop 8). This process is repeated until the sample is cut. The whole process does not require the use of a ruler, making the operation convenient and quick.

[0018] Furthermore, the distance between the first fixed-distance stop 8 and the adjacent second fixed-distance stop 9 is equal. The spacing is set according to the single-plate pattern, so that one advance allows the telescopic push block 4 to push out a row of patterns, which is convenient for direct cutting with the slitting cutter 2.

[0019] Furthermore, a telescopic rod support plate 12 is provided on the side of the vertical structural plate 11 opposite to the slitting cutter 2. The telescopic rod support plate 12 has a relief hole 13, through which the telescopic rod 5 passes. No bearing is needed at the relief hole 13; the diameter of the relief hole 13 only needs to be slightly larger than that of the telescopic rod 5. The function of the telescopic rod support plate 12 is to support the telescopic rod 5 (the other end of the telescopic rod 5 is supported by the telescopic push block 4), which can greatly improve the comfort of use.

[0020] Furthermore, an anti-detachment structure 14 is provided at the connection between the telescopic rod 5 and the telescopic push block 4. The anti-detachment structure 14 has a recessed groove 15, and an anti-detachment male ring 16 is provided at the end of the telescopic rod 5. The anti-detachment male ring 16 is rotatably engaged within the recessed groove 15. Connecting the telescopic rod 5 to the telescopic push block 4 significantly improves ease of use; not only can its extension change the position of the telescopic push block 4, but its retraction also drives the telescopic push block 4 to move.

[0021] Furthermore, an anti-tilting cover 17 is provided above the vertical structural plate 11. The anti-tilting cover 17 is fixedly connected to the vertical structural plate 11 by bolts, and the bottom of the anti-tilting cover 17 abuts against the top of the telescopic push block 4. The main function of the anti-tilting cover 17 is to maintain balance and prevent the telescopic push block 4 from tilting due to the weight of the handle 6 on the telescopic rod 5. The anti-tilting cover 17 must be installed, especially when a wooden handle is used. If the telescopic rod 5 and handle 6 are made of lightweight plastic material, the anti-tilting cover 17 is not required. The side of the anti-tilting cover 17 near the front should not be blocked, and the status of the internal stop and the movable stop 10 can be observed through this gap.

[0022] Structural Description: Cutting plate 1: The basic load-bearing structure of the tool, with a slitting guillotine 2 set on one side, a fixed limit strip 3 and a first fixed distance stop 8 fixed on it, and a vertical structural plate 11 installed to provide installation support for each component and ensure the stability of the overall structure; Slitting cutter 2: Located on one side of the cutting plate 1, it is a cutting component for lenticular printed samples, used to precisely cut the samples pushed to the appropriate position; Limiting strip 3: Two sets of parallel structures fixed on the cutting plate 1. The two sets form a limiting groove corresponding to the large sample, which can limit the sample displacement laterally and prevent the sample from shifting during the cutting process. Telescopic push block 4: Set between two sets of limiting strips 3, it can move forward and backward relative to the slitting guillotine 2. One side is connected to the telescopic rod 5, and the other side abuts against the sample. It is used to push the sample towards the slitting guillotine 2 under the action of the telescopic rod 5. Telescopic rod 5: It is set on the side of the telescopic push block 4 away from the slitting guillotine 2. The end is provided with a handle 6 and a relief hole 13 passing through the telescopic rod support plate 12. The end is connected to the telescopic push block 4 through the anti-detachment structure 14, which is used to drive the telescopic push block 4 to move back and forth. Handle 6: Fixed to the end of the telescopic rod 5, for the operator to hold and push the telescopic rod 5 to push the sample, or rotate to drive the movable stop 10 to switch the posture; Fixed-distance advance component 7: set on the outside of the limiting strip 3, including multiple sets of first fixed-distance stops 8, multiple sets of second fixed-distance stops 9 and movable stops 10, used to realize fixed-distance pushing of samples to ensure accurate cutting size each time; First fixed-distance stop 8: Multiple sets of structures vertically fixed on the cutting plate 1, arranged alternately with the second fixed-distance stop 9, with a height higher than the height of the movable stop 10 facing one side, used to block the movable stop 10 and make the sample extend a fixed distance. Second fixed distance stop 9: Multiple sets of structures are vertically fixed on the side of the vertical structure plate 11 near the first fixed distance stop 8, and are staggered with the first fixed distance stop 8. The height is higher than the posture height of the movable stop 10 facing its side, and works with the first fixed distance stop 8 to achieve reciprocating fixed distance. Movable stop 10: A structure fixed on the telescopic rod 5, which can rotate with the telescopic rod 5 to switch postures, and cooperate with the first fixed distance stop 8 and the second fixed distance stop 9 to limit the movement and control the fixed distance of the sample each time it extends. Vertical structure plate 11: A structure that is vertically fixed to the outside of the first fixed distance stop 8 near the cutting plate 1, with a second fixed distance stop 9 on one side, a telescopic rod support plate 12 on the side away from the slitting guillotine 2, and an anti-tilting cover 17 on the top, used to install and fix related components and provide support; Telescopic pole support plate 12: A structure fixed on the side of the vertical structural plate 11 away from the slitting guillotine 2, with an opening 13 on the top for bearing the telescopic pole 5, and together with the telescopic push block 4, it supports both ends of the telescopic pole 5, improving the comfort of operation; Hole 13: A hole-like structure opened on the telescopic rod support plate 12, with a hole diameter slightly larger than the telescopic rod 5, allowing the telescopic rod 5 to pass through, so that the telescopic rod 5 can slide smoothly without bearings; Anti-detachment structural component 14: A structure installed at the connection between the telescopic rod 5 and the telescopic push block 4, with an internal groove 15 for connecting the telescopic rod 5 and the telescopic push block 4 to prevent them from detaching during movement; Groove 15: A groove-shaped structure inside the anti-detachment structural component 14, which allows the anti-detachment male ring 16 at the end of the telescopic rod 5 to rotate and engage, thereby realizing the rotational connection between the telescopic rod 5 and the telescopic push block 4 and preventing detachment. Anti-detachment male ring 16: A ring-shaped structure set at the end of the telescopic rod 5, which is rotatably engaged in the female groove 15 of the anti-detachment structure 14, ensuring that the telescopic rod 5 can rotate relative to the telescopic push block 4, while preventing the two from detaching. Anti-tilting cover 17: A structure that is fixed to the top of the vertical structural plate 11 by bolts. The bottom of the cover abuts against the top of the telescopic push block 4 to balance the weight of the handle 6 and prevent the telescopic push block 4 from tilting up. The bottom side near the front is not blocked, so the internal stop and the status of the movable stop block 10 can be observed.

[0023] Working principle: Before operation, initial preparations must be completed. The operator first places the large sample of the grating card to be slit into the limiting groove of the cutting plate 1. This limiting groove consists of two sets of mutually parallel limiting strips 3 fixed on the cutting plate 1. Its size is adapted to the large sample and can limit the sample displacement laterally to prevent the sample from shifting during the slitting process. When placing the sample, ensure that one end of the sample is tightly against the telescopic push block 4 (the telescopic push block 4 is located between the two sets of limiting strips 3 and can move back and forth relative to the slitting cutter 2 during operation), and the other end faces the slitting cutter 2, so as to provide a reference positioning for subsequent pushing and slitting. At the same time, it must be confirmed that the bottom of the anti-tilting cover 17 (fixed to the top of the vertical structure plate 11 by bolts) is against the top of the telescopic push block 4. If the handle 6 is made of a heavier material such as wood, the anti-tilting cover 17 can balance the weight of the handle 6, prevent the telescopic push block 4 from tilting upward due to uneven force, and ensure the stability of the pushing process. If the telescopic rod 5 and handle 6 are made of lightweight plastic, this balancing structure can be omitted, but it is still necessary to ensure that all components are firmly connected.

[0024] During the actual slitting, the operator holds the handle 6 at the end of the telescopic rod 5 and pushes the telescopic rod 5 towards the slitting guillotine 2. One end of the telescopic rod 5 passes through the relief hole 13 on the telescopic rod support plate 12 on the side of the vertical structural plate 11 away from the slitting guillotine 2 (the relief hole 13 has a diameter slightly larger than the telescopic rod 5, allowing for smooth sliding without bearings, while also supporting the telescopic rod 5 and working together with the telescopic push block 4 to support both ends of the telescopic rod 5, improving operational comfort). The other end is connected to the telescopic push block 4 through the anti-detachment structure 14 (the anti-detachment male ring 16 at the end of the telescopic rod 5 rotates and engages in the female groove 15 of the anti-detachment structure 14, ensuring that the telescopic rod 5 can rotate relative to the telescopic push block 4 while preventing them from detaching, achieving a two-way linkage of "push-retract"). Pushing the telescopic rod 5 simultaneously drives the telescopic push block 4 forward, thereby pushing the sample closer to the slitting guillotine 2.

[0025] At this point, the fixed-distance advance assembly 7 begins to play a precise positioning role: the fixed-distance advance assembly 7 consists of multiple sets of first fixed-distance stops 8 and second fixed-distance stops 9 arranged in an alternating fixed manner, and a movable stop 10 fixed on the telescopic rod 5. In the initial state, the movable stop 10 is in the posture corresponding to the first fixed-distance stop 8. As the telescopic rod 5 is pushed, the movable stop 10 moves forward synchronously with the telescopic rod 5. When the movable stop 10 abuts against a certain set of first fixed-distance stops 8 (the first fixed-distance stops 8 are vertically fixed on the cutting plate 1, and their height is higher than the height of the corresponding posture of the movable stop 10, which can effectively prevent the movable stop 10 from moving forward), the sample just extends a fixed distance - this distance is consistent with the sample size of the single-plate grating card. The operator does not need to use a ruler to measure, but can directly press the sample to operate the slitting cutter 2 to complete a slitting operation, ensuring accurate slitting dimensions.

[0026] After the first slitting is completed, the operator turns handle 6, causing the telescopic rod 5 and the movable stop 10 fixed thereon to rotate, so that the movable stop 10 switches to the posture corresponding to the second fixed-distance stop 9 (the second fixed-distance stop 9 is vertically fixed on the side of the vertical structural plate 11 near the first fixed-distance stop 8, and its height is higher than the height of the corresponding posture of the movable stop 10, and the distance between the first fixed-distance stop 8 and the adjacent second fixed-distance stop 9 is equal, all matching the size of the single-plate sample). Then, the telescopic rod 5 is pushed towards the slitting guillotine 2, and the movable stop 10 moves forward with the telescopic rod 5 until it hits the next set of second fixed-distance stops 9. The sample extends again to the fixed distance matching the single-plate sample. The operator repeats the action of pressing the sample and operating the slitting guillotine 2 to complete the second slitting.

[0027] Following the repetitive operation of the above-described process of "rotating the movable stop 10 to switch postures – pushing the telescopic rod 5 to the stop limit – cutting," the first fixed-distance stop 8 and the second fixed-distance stop 9 are used alternately to continuously push the sample at a fixed distance until the entire large sample sheet is cut into several single-sheet grating cards that meet the size requirements. Throughout the process, the cooperation of the movable stop 10 and the staggered stops replaces the use of a ruler for measurement, which not only avoids visual interference and positioning errors caused by dynamic changes in the grating pattern, but also achieves rapid and accurate positioning through the mechanical structure, greatly improving cutting efficiency and quality stability.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
