Description

Technical Field

[0001] This utility model relates to the field of thin film cutting technology, specifically to a device for cutting thin films. Background Technology

[0002] A thin film is a thin, flexible, transparent sheet. It is made of plastics, adhesives, rubber, or other materials. Scientifically, a thin film is a two-dimensional material formed by the deposition of atoms, molecules, or ions onto the surface of a substrate. Examples include optical thin films, composite thin films, superconducting thin films, polyester films, nylon films, and plastic films. Thin films are widely used in the electronics, machinery, and printing industries.

[0003] In the early stages of existing material research and development, to obtain a 5mm wide wrapping film with smooth edges and small width error, it is only possible to manually cut long films of several tens of centimeters in length along the edge of a steel ruler using scissors or utility knives. This results in uneven force, making it difficult to control precision and causing burrs after cutting.

[0004] Therefore, a solution is needed. Utility Model Content

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] Example 1

[0027] To address the aforementioned problems: In the early stages of existing material research and development, to obtain a 5mm wide wrapping film with smooth edges and minimal width error, it is only possible to manually cut long films, which are tens of centimeters in length, along the edge of a steel ruler using scissors or utility knives. This results in uneven force, making it difficult to control precision and causing burrs after cutting.

[0028] The solution is as follows: A device for cutting a film includes a device body 1, the device body 1 includes a mounting rod 2 and a cutting device 3, the cutting device 3 is sleeved on the mounting rod 2; the cutting device 3 includes a first side mounting plate 4, a second side mounting plate 5, a blade mounting plate 6, a cutting blade 7 and a through bolt 17, the blade mounting plate 6 is provided in several groups, the several groups of blade mounting plates 6 are installed in a transversely equidistant manner between the first side mounting plate 4 and the second side mounting plate 5, the first side mounting plate 4, the second side mounting plate 5 and the several groups of blade mounting plates 6 are connected by locking bolts 18, the locking bolts 18 are equipped with locking nuts 19; the blade mounting plate 6 has a rectangular structure, the blade mounting plate 6 has an inner plate blade mounting groove 16 on one side, the inner plate blade mounting groove 16 has a set of blade through holes 10, and the blade mounting plate 6 has a set of embedding holes 15 on its surface.

[0029] Analysis of the above: During installation, the operator can embed the cutting blade 7 into the inner blade mounting groove 16 on the blade mounting plate 6. Multiple blade mounting plates 6 with cutting blades 7 are then stacked. The operator sequentially passes the locking bolt 18 through the blade insertion holes 10 of the second side mounting plate 5 and the blade mounting plate 6, then through the blade hole 13 of the cutting blade 7, and finally into the blade insertion hole 10 of the first side mounting plate 4. The operator then uses the locking nut 19 to tighten it, and finally installs the bolt body 17 into the blade insertion hole 10 for further fixation. This method improves the stability between the second side mounting plate 5, the blade mounting plate 6, the cutting blade 7, and the first side mounting plate 4. The fixture is installed on the frame for film operation. The blade is adjusted to a suitable height and angle to maintain uniform film speed. The blade naturally cuts the film, resulting in a film strip of uniform width, flatness, and no burrs.

[0030] Example 2:

The surfaces of the first side mounting plate 4 and the second side mounting plate 5 are also provided with bolt through holes 9.

[0032] Analysis of the above content: The side plate blade mounting groove 8 on the outer side of the first side mounting plate 4 and the second side mounting plate 5 is also for the purpose of facilitating the embedding of the cutting blade 7. Then, the insertion of the inserting bolt 17 is used for limiting, and then the two ends of the inserting bolt 17 can be locked with nuts.

[0035] Analysis of the above content: When the first side mounting plate 4 and the second side mounting plate 5 are installed onto the mounting rod 2, the socket holes 11 of the first side mounting plate 4 and the second side mounting plate 5 are fitted onto the mounting rod 2. Then, the worker uses a bolt to insert into the locking hole 12 at the rear end of the first side mounting plate 4 and the second side mounting plate 5. Then, the front end of the bolt can be rotated to push against the mounting rod 2. In this way, the cutting device 3 can be installed onto the mounting rod 2.

[0037] Please see Figure 1-5 The present invention provides a technical solution based on Embodiment 1: the cutting blade 7 has a trapezoidal structure, and the surface of the cutting blade 7 has a blade hole 13, which has a long groove structure.

[0038] Analysis of the above content: The cutting blade 7 has a hole 13 on its surface to facilitate the insertion of the bolt 17, thereby limiting and fixing the cutting blade 7.

[0040] Please see Figure 1-5 The present invention provides a technical solution based on Embodiment 1: the inserting pin 17 has a cylindrical structure, and the inserting pin 17 passes through the blade hole 13 and the blade insertion hole 10 respectively.

[0041] Analysis of the above content: The insert pin 17 is inserted into the blade insertion hole 10 of the second side mounting plate 5 and the blade mounting plate 6 in sequence, then through the blade hole 13 of the cutting blade 7, and then into the blade insertion hole 10 of the first side mounting plate 4, thereby improving the stability between the second side mounting plate 5, the blade mounting plate 6, the cutting blade 7 and the first side mounting plate 4, and also to achieve the purpose of limiting the position.

[0042] To further demonstrate the novelty and feasibility of this solution, the following relevant data is provided:

[0043] Comparison of technical effects of thin film cutting devices

[0044] Comparison Projects Existing manual cutting technology This utility model device Cutting width error ±0.8-1.2mm ±0.1-0.3mm Edge roughness length 1-2mm ≤0.5mm Time required for a single cut 15-20 seconds / 10cm 5-8 seconds / 10cm Continuous operation stability Accuracy decreases with prolonged operation time Maintain high precision Width consistency (n=50) Error fluctuation range ±1mm Error fluctuation range ±0.2mm

[0045] Data Description

[0046] Cutting width error

[0047] Existing technology: When manually cutting along a steel ruler using scissors or a utility knife, the width error is relatively large due to uneven human force control, with a typical value of ±0.8-1.2mm, which is difficult to meet the 5mm precision width requirement.

[0048] Improved solution: By using equally spaced blade mounting plates (lateral spacing accuracy ±0.1mm) and locking bolts to fix the structure, and in conjunction with uniform speed film operation, the width error can be controlled within ±0.3mm to meet high precision requirements.

[0049] Edge roughness length

[0050] Existing technology: Uneven cutting force during manual cutting causes the film edges to tear, with rough edges typically ranging from 1 to 2 mm in length, requiring secondary processing.

[0051] Improved solution: The scalpel blades are arranged horizontally and fixed firmly, forming a neat cutting surface when slicing through the membrane, with a burr length of ≤0.5mm, requiring no subsequent trimming.

[0052] Time required for a single cut

[0053] Existing technology: Manually aligning the steel ruler and controlling the cutting speed, it takes 15-20 seconds to cut a 10cm film, which is inefficient.

[0054] Improved solution: After the device is fixed to the film running frame, it can continuously and automatically cut, and a 10cm cut only takes 5-8 seconds, improving efficiency by about 3 times.

[0055] Continuous operation stability

[0056] Existing technology: Long-term manual operation can easily lead to fatigue, resulting in a decrease in cutting accuracy in the later stages, with error fluctuations reaching ±1mm.

[0057] Improvement solution: The 3D resin-printed fixture module has high rigidity, and the bolt locking structure prevents the blade from shifting. After 50 consecutive operations, the error is still kept within ±0.2mm.

[0058] Width Consistency

[0059] Test conditions: 50 10cm long films were cut using two different methods, and the width data was measured.

[0060] Current technology: Among 50 samples, the width fluctuation range reached ±1mm, and the pass rate (5±0.5mm) was only 62%.

[0061] Improved solution: The width of all 50 samples was within the range of 5±0.3mm, with a pass rate of 100%, demonstrating a high degree of consistency.

[0062] Summary of technical advantages

[0063] This invention improves cutting precision from millimeters (manual operation) to sub-millimeter level through an equidistant blade arrangement structure and a rigid clamping system, while simultaneously solving the problems of burrs and efficiency. Data shows that this device can significantly improve product quality and production efficiency in precision thin film processing scenarios, and is particularly suitable for the high-precision requirements of thin films with specific widths such as 5mm in the early stages of R&D.

Side plate blade mounting groove; 9. Bolt insertion hole; 10. Blade insertion hole; 11. Sleeve hole; 12. Locking hole; 13. Blade hole itself; 16. Inner plate blade mounting groove; 17. Insertion bolt; 18. Locking bolt; 19. Locking nut. All components are general standard parts or parts known to those skilled in the art, and their structure and principle can be understood by those skilled in the art through technical means. As learned from the book or through conventional experimental methods, the problem solved by this utility model is that in the early stages of existing material research and development, in order to obtain a wrapping film with a 5mm width, smooth edges, and small width error, it is only possible to manually cut long films of tens of centimeters in length along the edge of a steel ruler using scissors or utility knives. This results in uneven force, making it difficult to control the precision and causing burrs after cutting. This utility model, through the combination of the above-mentioned components, uses horizontally arranged and tightly secured surgical blades with equal spacing to cut across the film surface, which can effectively ensure the precise cutting width.
