Description

Technical Field

[0001] The invention relates to the technical field of color card production, in particular to a color card cutting and polishing process. Background Art

[0002] Color cards, also often called color cards, are a type of printed material that is widely used in various occasions. They are usually made of high-quality paper, plastic or other composite materials, and use professional printing technology to achieve colorful designs and information display.

[0003] Traditional mechanical cutting of color card cutting relies on physical knives, which will wear out after long-term use, resulting in reduced cutting quality, burrs, irregular edges and other problems, and prone to mechanical inaccuracy. When the moving parts of the mechanical cutting equipment produce errors due to long-term use or improper maintenance, it will lead to problems such as inaccurate cutting position and size deviation.

[0004] On the other hand, in order to prevent deformation and facilitate blanking when making color cards, the traditional punching method usually requires a large margin on both sides of the color card. This method leads to a large amount of excess waste, increases the production cost, and the traditional mechanical cutting and punching method has poor adaptability to composite paper and thin plastics, which can easily cause deformation or damage to the material. Therefore, the inventors have proposed a color card cutting and polishing process to solve the above-mentioned technical problems. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings, the invention aims to provide a technical solution that can solve the above-mentioned problems.

[0006] A color card cutting and polishing process, the process comprising the following steps:

[0007] (a) Preparation stage: Select color card raw materials that meet the specifications;

[0008] In this stage, raw materials that meet the specifications for making color cards are selected to ensure the basic quality of subsequent processing and the quality of the finished products. Accurate selection helps reduce waste in the production process caused by unqualified materials and improve resource utilization;

[0009] (b) Cutting stage: using high-precision cutting equipment to cut the color card raw material to form a color card of a predetermined shape and size, wherein the cutting equipment is equipped with an automatic pressure adjustment system to ensure that the surface of the material is not damaged during the cutting process;

[0010] In this stage, high-precision cutting equipment is used to cut the raw materials of color cards, which can form color cards of predetermined shapes and sizes to meet the needs of different application scenarios. The cutting equipment is equipped with an automatic pressure adjustment system to ensure that the surface of the material is not damaged during the cutting process, maintain the original characteristics of the material, and improve the yield rate;

[0011] In addition, this stage improves the process steps of obtaining color card products by traditional punching. The traditional punching method requires that when punching color card products, margins must be left on both sides to avoid deformation of the color card and facilitate blanking of the color card. However, this method results in too much residual waste after the punching process is completed, thereby increasing the production cost;

[0012] (c) Initial polishing stage: Put the cut color cards into the color card polishing machine, use a low-roughness polishing wheel to perform preliminary polishing on the edge of the color card, remove burrs and initially smooth the edge. In this stage, a low-roughness polishing wheel is used to perform preliminary polishing on the edge of the color card, effectively remove burrs and initially smooth the edge, laying a good foundation for subsequent fine polishing. The preliminary polishing can not only improve the appearance of the color card, but also provide a smoother working surface for subsequent processing, reducing the difficulty of subsequent processes;

[0013] (d) Fine polishing stage: Based on the initial polishing, a higher precision polishing wheel is used to perform a secondary polishing on the edge of the color card until the preset smoothness standard is reached;

[0014] In this stage, based on the initial polishing, a higher-precision polishing wheel is used to perform a secondary polishing on the edge of the color card until the preset smoothness standard is reached, making the edge of the color card more rounded and smooth, improving the overall aesthetics. The finely polished color card feels good and has no sharp edges, which enhances the user's comfort and satisfaction;

[0015] (e) Quality inspection stage: The polished color cards are visually inspected to ensure that there are no obvious flaws or defects, thus ensuring the quality of the products leaving the factory. Through precise material selection and efficient production processes, the scrap rate and rework times are reduced, production costs are reduced, and economic benefits are improved.

[0016] Furthermore, in the cutting stage (b), the high-precision cutting equipment includes a laser cutting device, and the laser cutting can achieve a cutting accuracy of micrometer level;

[0017] This method ensures that the size and shape of the color card are extremely accurate, meeting the product requirements of quality and standards. Compared with traditional mechanical cutting methods, laser cutting reduces the errors caused by tool wear or inaccurate mechanical movement, and improves the consistency and reliability of the finished product.

[0018] Moreover, laser cutting is a non-contact processing method, which avoids the scratches or damage that may be caused by direct contact between traditional cutting tools and the material surface, and maintains the original appearance and physical properties of the color card material. At the same time, the laser cutting equipment can be equipped with a cooling system or use a short-pulse laser. The use of this structure can effectively control the heat-affected zone and reduce the risk of material deformation or discoloration.

[0019] Furthermore, in the initial polishing stage (c), the low-roughness polishing wheel is made of a diamond coating, and its surface roughness is controlled between 0.1 μm and 0.5 μm;

[0020] Diamond coated polishing wheels are used to polish the color cards so that the surface roughness is controlled between 0.1μm and 0.5μm, achieving fine surface treatment and ensuring the smoothness and consistency of the edges of the color cards. This polishing process helps to remove burrs and smooth the edges, laying a good foundation for subsequent fine polishing. In addition, due to the extremely high hardness and wear resistance of the diamond coating, the polishing wheel can maintain a consistent surface roughness during the working process, ensuring that each color card edge can obtain a uniform and consistent polishing effect;

[0021] In addition, diamond is one of the hardest materials in nature, and its coating gives the polishing wheel extremely high wear resistance. Compared with traditional grinding wheels or ceramic wheels, diamond-coated polishing wheels can still maintain good performance after long-term use, reducing replacement frequency, reducing maintenance costs, reducing wear and deformation, and making the polishing wheel less likely to wear or deform during processing, ensuring long-term and stable polishing quality.

[0022] Furthermore, in the fine polishing stage (d), the higher precision polishing wheel is made of ceramic fiber material, and its surface roughness is 0.02 μm-0.05 μm;

[0023] The use of ceramic fiber as a polishing wheel makes the polishing wheel wear-resistant and pressure-resistant, and can maintain good performance after long-term use, reducing the frequency of replacement and maintenance costs. The ceramic fiber polishing wheel can effectively remove the tiny burrs remaining after the initial polishing and the fine flaws on the flat edge, thereby improving the polishing efficiency;

[0024] In addition, due to the precise control during the polishing process, secondary defects such as scratches and dents caused by improper polishing are reduced, and the yield and product quality of color cards are improved. The ceramic fiber polishing wheel produces less waste during the polishing process and does not require the use of chemical solvents, which is more environmentally friendly. At the same time, its efficient cutting and grinding capabilities also reduce unnecessary material waste.

[0025] Furthermore, a cleaning step is included between the cutting stage (b) and the initial polishing stage (c) to remove debris and dust remaining after cutting;

[0026] The detailed process of this cleaning step is:

[0027] ① Prepare cleaning equipment: Use ultrasonic cleaning machine, high-pressure air gun or special cleaning brush to make the equipment in normal working condition, and prepare the required cleaning liquid, deionized water, alcohol or other cleaning agents suitable for cleaning color card materials;

[0028] ② Preliminary cleaning: Use a soft brush or compressed air gun to gently remove large debris and dust left after cutting to prevent large particles of impurities from entering the subsequent fine cleaning process;

[0029] ③ Classification treatment: Arrange the cut color cards by batches to ensure that each batch of products can be evenly cleaned. Put the preliminarily cleaned color cards into an ultrasonic cleaning tank filled with an appropriate amount of cleaning liquid, set an appropriate cleaning time and frequency, the time is 3 minutes to 12 minutes. After the cleaning is completed, rinse the color cards thoroughly with clean water or deionized water to remove the residual cleaning liquid;

[0030] ④ Drying: Use a high-pressure air gun to thoroughly dry the moisture and residue on the surface of the color card to ensure that there is no water stain or residual liquid, and check whether the color card is completely dry. Then, perform an appearance inspection on the cleaned color card to ensure that there is no obvious dust, debris or other contaminants remaining;

[0031] ⑤Classification and storage: The cleaned color cards are classified and stored according to specifications and batches, ready to enter the next step of initial polishing.

[0032] Furthermore, the quality inspection stage (e) further includes a packaging step, using dustproof bags or vacuum packaging to protect the finished color cards from external contamination;

[0033] The detailed process of this packaging step is:

[0034] ① Prepare packaging materials: use dust-proof bags, vacuum packaging bags, labels, and sealing machines, and check whether they meet environmental protection standards and product quality requirements;

[0035] ②Classify and organize the finished color cards: Classify and organize the finished color cards that have passed the quality inspection according to different specifications and batches to ensure that the products of the same batch can be evenly packaged;

[0036] ③ Remove surface dust: Before packaging, use a clean soft cloth or compressed air gun to gently wipe the surface of the color card again to ensure that there is no dust or other contaminants remaining. For color cards that need to be packaged separately, use dustproof bags to package them one by one, and carefully place the color cards in the dustproof bags to ensure that the edges are not damaged;

[0037] ④ Sealing: Use a sealing machine to heat-seal or tape-seal the dust-proof bag to ensure that the bag is well sealed to prevent dust from entering. For color cards that need to be packaged in batches, vacuum packaging can be used. Place a certain number of color cards neatly in a vacuum packaging bag, and pay attention to avoid overlapping or squeezing. Use a vacuum packaging machine to vacuum the packaging bag to remove the air in the bag, ensure that the color card fits tightly but is not deformed by pressure. After vacuuming, immediately use a sealing machine to seal the vacuum packaging bag to ensure that the packaging bag is completely closed to prevent air from re-entering.

[0038] ⑤ Add logos and labels: Add necessary logos and labels on each packaging bag, including product name, specifications, batch number, production date, and expiration date information, to facilitate subsequent management and tracking. Put the packaged color cards into appropriate outer packaging boxes and use foam boards or bubble films for buffering protection to prevent collision or extrusion during transportation;

[0039] ⑥ Warehousing or delivery: Store the packaged finished color cards in a dry, well-ventilated warehouse, avoid direct sunlight and humid environment, to ensure long-term storage; or take the finished color cards out of the warehouse according to the order requirements and prepare for delivery. Before delivery, check again whether the packaging is intact to ensure safe delivery to the designated user's location.

[0040] Furthermore, the raw material of the color card is one or more combinations of PVC, PET or composite paper materials;

[0041] When using PVC (polyvinyl chloride), PVC material has high tear strength and is suitable for cards that need to be used for a long time, such as membership cards and coupons. PVC also has good chemical corrosion resistance and is not easily affected by daily chemicals, making it suitable for use in a variety of environments. In addition, PVC is a thermoplastic that can be formed by heating and cooling, which is convenient for cutting, polishing and other post-processing processes. It is suitable for high-resolution printing and can present bright colors and clear text patterns.

[0042] When using PET (polyethylene terephthalate), PET is recyclable, in line with the concept of green production, and helps reduce environmental pollution. PET releases fewer harmful substances during production and use, and has high mechanical strength and rigidity. It can withstand large external forces without being easily deformed. It also has good transparency and is suitable for application scenarios that require a transparent effect, such as transparent business cards or display cards.

[0043] When composite paper materials are used, composite paper materials have a unique natural texture, comfortable feel, and give people a high-end feeling, which is suitable for high-end product design. Composite paper can be combined with other materials, such as metal foil and plastic film, to create a variety of visual and tactile effects to enhance the attractiveness of the product. It is suitable for various printing technologies, including offset printing, screen printing and digital printing, and can achieve highly customized designs. Compared with plastic materials, composite paper has a lower cost and is suitable for large-scale production while maintaining a high-quality appearance and feel;

[0044] By combining two or more of PVC, PET and composite paper materials, the advantages of each material can be fully utilized to make up for their respective shortcomings. The durability of PVC and the transparency of PET can be combined to produce cards that are both sturdy and beautiful. The combination of different materials makes color cards adaptable to a wider range of application needs. The combination of composite paper and PVC can produce membership cards that have both high-end texture and good durability.

[0045] Furthermore, the process is suitable for making business cards, membership cards, and coupons, and the process steps cover various color card products or card products.

[0046] Compared with the prior art, the beneficial effects of the present invention are: improving the traditional mechanical cutting method, reducing the error caused by tool wear or inaccurate mechanical movement through laser cutting, and improving the consistency and reliability of the finished product;

[0047] It also avoids scratches or damages that may be caused by direct contact between traditional cutting tools and the material surface, and maintains the original appearance and physical properties of the color card material. In addition, this process improves the traditional process steps of obtaining color card products using punching. The traditional punching method requires that when punching color card products, margins must be left on both sides to avoid deformation of the color card and facilitate the blanking of the color card. However, this method results in too much remaining waste after the punching process is completed, thereby increasing the production cost. DETAILED DESCRIPTION

[0056] (d) Fine polishing stage: Based on the initial polishing, a higher precision polishing wheel is used to perform a secondary polishing on the edge of the color card until the preset smoothness standard is reached;

[0057] In this stage, based on the initial polishing, a higher-precision polishing wheel is used to perform a secondary polishing on the edge of the color card until the preset smoothness standard is reached, making the edge of the color card more rounded and smooth, improving the overall aesthetics. The finely polished color card feels good and has no sharp edges, which enhances the user's comfort and satisfaction;

[0058] (e) Quality inspection stage: The polished color cards are visually inspected to ensure that there are no obvious flaws or defects, thus ensuring the quality of the products leaving the factory.

[0059] In the cutting stage (b), the high-precision cutting equipment includes a laser cutting device, and the laser cutting can achieve a cutting accuracy of micrometer level;

[0060] This method ensures that the size and shape of the color card are extremely accurate, meeting the product requirements of quality and standards. Compared with traditional mechanical cutting methods, laser cutting reduces the errors caused by tool wear or inaccurate mechanical movement, and improves the consistency and reliability of the finished product.

[0061] Moreover, laser cutting is a non-contact processing method, which avoids the scratches or damage that may be caused by direct contact between traditional cutting tools and the material surface, and maintains the original appearance and physical properties of the color card material. At the same time, the laser cutting equipment can be equipped with a cooling system or use a short-pulse laser. The use of this structure can effectively control the heat-affected zone and reduce the risk of material deformation or discoloration.

[0062] In the initial polishing stage (c), the low-roughness polishing wheel is made of a diamond coating, and its surface roughness is controlled between 0.1 μm and 0.5 μm;

[0063] Diamond coated polishing wheels are used to polish the color cards so that the surface roughness is controlled between 0.1μm and 0.5μm, achieving fine surface treatment and ensuring the smoothness and consistency of the edges of the color cards. This polishing process helps to remove burrs and smooth the edges, laying a good foundation for subsequent fine polishing. In addition, due to the extremely high hardness and wear resistance of the diamond coating, the polishing wheel can maintain a consistent surface roughness during the working process, ensuring that each color card edge can obtain a uniform and consistent polishing effect;

[0064] In addition, diamond is one of the hardest materials in nature, and its coating gives the polishing wheel extremely high wear resistance. Compared with traditional grinding wheels or ceramic wheels, diamond-coated polishing wheels can still maintain good performance after long-term use, reducing replacement frequency, reducing maintenance costs, reducing wear and deformation, and making the polishing wheel less likely to wear or deform during processing, ensuring long-term and stable polishing quality.

[0065] In the fine polishing stage (d), the higher precision polishing wheel is made of ceramic fiber material, and its surface roughness is 0.02 μm-0.05 μm;

[0066] The use of ceramic fiber as a polishing wheel makes the polishing wheel wear-resistant and pressure-resistant, and can maintain good performance after long-term use, reducing the frequency of replacement and maintenance costs. The ceramic fiber polishing wheel can effectively remove the tiny burrs remaining after the initial polishing and the fine flaws on the flat edge, thereby improving the polishing efficiency;

[0067] In addition, due to the precise control during the polishing process, secondary defects such as scratches and dents caused by improper polishing are reduced, and the yield and product quality of color cards are improved. The ceramic fiber polishing wheel produces less waste during the polishing process and does not require the use of chemical solvents, which is more environmentally friendly.
