Description

TECHNICAL FIELD

[0001] The present application relates to the field of printing and dyeing equipment, in particular to a multifunctional large printing and dyeing equipment light weight high precision ink cartridge. BACKGROUND

[0002] Carbon fiber composite material as a new type of structural material is one of the ideal materials for high-performance products. Carbon fiber composite material has excellent physical properties, and has good specific strength and large specific stiffness. The mechanical properties can be controlled by designing raw materials to change the performance requirements of the product. The conventional components are usually made of conventional metal materials. The environmental factors have a greater impact on the accuracy of the ink cartridge. Carbon fiber composite material has more design flexibility and can have the desired physical properties.

[0003] In the field of high-end equipment manufacturing, carbon fiber composite material has become an ideal choice to replace traditional metal materials due to its excellent specific strength (strength / density), specific stiffness (stiffness / density) and designability.

[0004] However, the traditional metal cavity: adopts solid customized aluminum alloy extrusion forming, and is treated by anodic hard oxidation and internal cavity Teflon coating. Although it has certain corrosion resistance, the inherent weight (density about 2.7g / cm³) of the metal material leads to high equipment load and high energy consumption. Changes in environmental temperature / humidity easily cause thermal expansion and cold contraction deformation (aluminum alloy thermal expansion coefficient about 23x10⁻ 6 / ℃), which directly affects the ink coating accuracy. The existing non-metal cavity: is made by laying and pressing a carbon fiber cloth preform mold. Although it realizes lightweight (density about 1.6g / cm³), it is limited by the anisotropic properties of carbon fiber and traditional laying process, and has problems such as high surface roughness (Ra≥1.6μm), uncontrollable small deformation (deformation amount>0.15mm after long-term use), etc. It is difficult to meet the uniform ink supply demand under the condition of high-speed printing (>500m / min).

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution of the present application, and the advantages are more clear and obvious, the following will be further described in detail with the help of the attached drawings.

The scraper pressure plate 2 and the ink block seat 3 are of the same thickness and are processed by a machining center to ensure the thickness size. The surface is coated with a Teflon process. The scraper pressure plate 2 is provided with two groups, and the two groups of scraper pressure plates 2 are symmetrically distributed about the cavity body 1. The inside of the cavity body 1 is laid with 0° artificial laying, the second layer is 90°, and then the laying direction is changed to ±45° after reaching the middle value, and then 90° and 0° in turn. The angle of the processing step on the surface of the cavity body 1 meets the requirement of 18° angle (product performance layer design structure diagram).

[0020] Product performance layer design structure diagram

[0021] I. Cavity body —— lightweight and high-precision core carrier Material system: adopt special carbon fiber composite material (T700 level carbon fiber + high performance epoxy resin base) with modulus matching, fiber volume fraction 60%-65%, density only 1.6g / cm³ (40%-50% lighter than aluminum alloy), at the same time, with bending strength≥800MPa (far more than 300-400MPa of aluminum alloy), thermal expansion coefficient≤1.5×10⁻ 6 / ℃ (only 1 / 15 of aluminum alloy), double advantages, from the essence of materials to inhibit the deformation caused by environmental factors (such as temperature fluctuation).

[0022] Molding process: Break through the traditional layering process, using "digital mold flow analysis + high-precision mold integrated molding" technology: Optimize the fiber layering path through CAE mold flow simulation (accuracy up to 0.1°), ensure that the fiber orientation is highly matched with the stress direction; Use high-precision mold (processing accuracy ±0.005mm), realize the full-size integrated molding of the cavity body and the installation interface (scraper pressure plate, ink block seat, etc.), completely eliminate the assembly error of traditional splicing process (traditional process assembly error >0.03mm); Surface roughness Ra≤0.8μm (no secondary processing), directly meet the requirements of precise coating on the smoothness of the cavity surface.

[0023] Second, the limit adjustment system - high-precision dynamic protection In view of the need for real-time accurate adjustment of the gap between the cavity and the scraper in high-speed printing, a collaborative limit adjustment system is designed: Limit tube assembly: The main body is made of carbon fiber reinforced thermoplastic plastic (CFRTP), with a density of 1.5g / cm³ (60% lighter than metal tube), and also has fatigue resistance (10 6 cycle without cracking); The positioning rod is threaded through the side through hole, realizing the rapid locking of the axial position (positioning error ≤0.005mm); The inner wall integrates the guide rod and the elastic limit card plate, forming a "axial - radial - circumferential" three-dimensional limit structure, cooperating with the surface thread groove (pitch 0.05mm) and the precision adjusting nut (accuracy ±0.002mm), which can dynamically control the gap between the cavity and the scraper (adjusting accuracy up to ±0.01mm); and the positioning card slot (tolerance ±0.003mm) of the cavity ink block seat forms a linkage cooperation, ensuring the stability of the ink path system (dynamic deformation <0.02mm) during high-speed printing (>800m / min).

[0024] Core innovation advantage (lightweight + high-precision dual breakthrough)

[0025] Through the above design, the invention not only realizes the performance leap of "lighter than existing non-metallic cavity (density reduction 11%), more accurate than traditional metal cavity (deformation reduction 90%)", but also through the deep binding of material formula, layering design and molding process, builds a technical barrier that is difficult to replicate by peers, providing core component support for the upgrading of large-scale printing and dyeing equipment to high-speed and precision.

[0026] A manufacturing procedure of a multifunctional lightweight high-precision ink box for large-scale printing and dyeing equipment S1, outer mold: a special steel mold capable of withstanding heat without deformation and having high precision is used during molding. After the mold is finished, anti-aging treatment and surface electron polishing treatment are performed. Before molding, a layer of special release liquid is applied to the surface to ensure that the product can be easily removed after curing. The corresponding carbon cloth model is taken out from the freezer, and it is confirmed whether the exposure time of the carbon cloth exceeds the standard required time. The carbon cloth is thawed at room temperature for 12 hours. The box needs to be opened during thawing. It is confirmed that there is no water droplet residue on the carbon cloth after thawing, and the carbon cloth is flat without wrinkles and material defects. The carbon cloth is placed on the cutting machine and cut according to the cutting size of the cavity design. After cutting, it is confirmed that the size is correct, and the size label is marked on the release paper; S2, appearance forming: pre-impregnated material is used to lay on the mold. The total number of steps is 12+N layers. The overall appearance is divided into two parts, each part has 3+N layers; S3, product forming: the inner and outer molds are formed by using high-strength and high-modulus carbon fiber pre-impregnated material in different directions (0°, 45°, 90°, etc.). The mold is divided into A and B two types. The two molds start with 7.5mm thick carbon cloth. According to the thickness of one layer of pre-impregnated material, which is 0.24mm, a total of 31+N layers need to be laid. Among them, 31+N layers need to ensure their symmetry, and then different angle unidirectional pre-impregnated material is inserted. The strength and rigidity of each direction are fully guaranteed, and the number of layers and pieces laid is recorded on the work report; S4, vacuumizing: each layer of carbon fiber layering needs to be combined with vacuumizing to make the carbon fiber pre-impregnated cloth tightly combined and the gap between layers is closed. The value of each vacuum is recorded. The outer mold uses high-precision metal products combined with film vacuumizing process; S5, curing: heat pressing tank is used for heating and pressing to cure. Carbon fiber maintains uniform stress state, maintains inherent precision, ensures that there is no gap between each layer of carbon fiber pre-impregnated material, and releases internal stress. After heating in the furnace again, the composite carbon fiber product is naturally cooled to room temperature, further releasing internal stress, avoiding deformation in the subsequent use of the product; S6, mechanical finishing: super-hard alloy tools are used for high-precision machining, and the hole deviation is confirmed after machining according to the drawing data. After that, the appearance of the product is polished and released; S7, measurement: quality management personnel use a series of measurement tools to measure the accuracy of the product and whether there are small errors, after subtle correction to make the product more in line with the standard, the appearance of the surface is bright without pores, the product as a whole is not scratch burr, the product is placed on the water platform and requires 0.01mm within the plug gauge, the step parallelism and flatness reach 0.0025mm requirements.
