Description

Technical Field

[0001] This utility model relates to the field of PVC film technology, and in particular to a PVC film printing and flocking integrated machine. Background Technology

[0002] Due to its excellent physical and chemical properties, such as wear resistance, corrosion resistance, insulation, and ease of processing, PVC film is widely used in many fields, including packaging, advertising, decoration, automotive interiors, and medical supplies. To enhance the added value and aesthetics of products, surface treatments of PVC film, such as printing patterns and flocking, have become common processes. Printing gives the film rich colors and patterns, while flocking provides a unique velvety texture and feel, increasing the product's grade and functionality, such as providing anti-slip, sound absorption, or heat insulation effects. Utility Model Content

[0003] The purpose of this invention is to solve the problem in the existing production model where PVC film is first printed with patterns on a dedicated printing machine, and after the ink dries, the semi-finished product is removed from the printing machine and transported to a flocking machine for subsequent flocking processing. This segmented operation leads to significant drawbacks. First, the process of transporting, positioning, and waiting for the ink to dry between different machines consumes a lot of time and manpower, greatly reducing production efficiency. Second, each transport and repositioning requires additional effort for calibration, and it is difficult to ensure high consistency, which can easily cause bottlenecks in the production line.

[0004] This utility model achieves the above objectives through the following technical solutions: A PVC film printing and flocking integrated machine includes a support frame. A flocking device is mounted on one side of the support frame, and a printing device is mounted on the other side of the flocking device. A PVC film conveyor line is mounted on the support frame. The printing device includes a Z-axis servo motor lifting device, a transverse servo motor moving device on one side of the Z-axis servo motor lifting device, and pressing and fixing devices at the upper and lower ends of the transverse servo motor moving device. A scraping device is mounted on one side of the transverse servo motor moving device. The pressing and fixing device includes two opposing fixing arms. A first lifting cylinder is mounted on the upper end of each fixing arm, and a pressing and fixing frame is mounted at the output end of each first lifting cylinder. A fixing locking plate is mounted on the inner side wall of each pressing and fixing frame. The fixed locking plate is equipped with locking bolts, integrating the two core processes of printing and flocking into one machine. This eliminates the time spent on handling, positioning, and waiting in intermediate steps, greatly improving production efficiency and reducing production costs and labor input. The PVC film conveyor line enables automated and continuous transmission of the film from printing to flocking, reducing human intervention, operational difficulty, and errors caused by manual operation. During the printing process, two opposing fixed arms, in conjunction with a lifting cylinder and a downward pressing frame, firmly press and fix the PVC film onto the worktable. The lifting cylinder provides rapid, uniform, and stable downward pressure, effectively preventing the film from shifting, wrinkling, or deforming during printing, ensuring the clarity and accuracy of the printed pattern.

[0005] Furthermore, the scraping device includes a fixed back plate, on one side of which are symmetrically arranged second lifting cylinders. Each of the second lifting cylinders has a guide rod at its output end, and a first scraper and a second scraper are arranged on the lower side of the guide rod. The two second lifting cylinders control the first and second scrapers respectively. The two independent lifting cylinders control the lifting and lowering of the first and second scrapers, meaning that the pressing and lifting of each scraper can be controlled individually according to printing needs, improving the flexibility of the printing process. The independently controlled dual-scraper system allows different scrapers to be used in the same printing process; for example, one scraper can be used for pre-coating or base color printing, while the other can be used for detail or special effects printing, thus achieving more complex and refined printing effects. The guide rods ensure that the scrapers remain vertically stable during lifting and lowering, avoiding wobbling, thereby ensuring the uniformity and consistency of ink scraping and improving printing quality.

[0006] Furthermore, both the first and second doctor blades have curved edges, with the first doctor blade having a greater curvature than the second doctor blade. This allows for different ink scraping effects. Compared to traditional right-angle doctor blades, the curved blades provide better control over ink rolling and transfer, reducing ink splashing and bubble formation, resulting in more delicate, uniform, and full printed patterns. The first doctor blade with a larger curvature (which is less sharp) may be suitable for scraping thicker ink layers, achieving better coverage and smoothness, such as for underprinting or large-area solid color printing. Conversely, the second doctor blade with a smaller curvature (which is sharper) may be suitable for scraping thinner ink layers, achieving finer lines, textures, or special effects printing. By adjusting the use of doctor blades with different curvatures, areas with different ink thicknesses, gloss levels, or tactile textures can be achieved on the same product, providing a richer visual and tactile experience and increasing the product's added value and market competitiveness.

[0007] Furthermore, the fixed back plate is also provided with an ink storage tank, which is connected to the first and second doctor blades through a pipe, and an ink flow control valve is provided on the pipe to adjust the ink supply. The introduction of the ink flow control valve allows the operator to accurately adjust the amount of ink supplied to the doctor blade according to the printing process, ink type and printing effect requirements, which is crucial for controlling the color depth, ink thickness and uniformity of the printed matter.

[0008] Furthermore, the support frame is also equipped with a waste collection trough, which is located below the end of the PVC film conveyor line and is used to collect waste and excess fluff generated during the printing and flocking process.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This integrated machine achieves fully automated continuous transmission from printing to flocking through a PVC film conveyor line, and precise fixation of the film by a pressing and fixing device. The equipment can effectively eliminate the errors and instabilities caused by manual handling, positioning and operation, which ensures that the printed pattern position of each batch of products is accurate and clear, and the flocking is uniform and firm, thereby greatly improving the uniformity and stability of product quality, reducing the scrap rate, and providing customers with high-quality and consistent products.

[0010] 2. The independently controlled dual-blade system (especially with differentiated blade curvature) combined with precise ink flow control gives the equipment extremely high printing process flexibility. It can not only achieve composite printing of base colors and details, thick and thin ink, creating complex patterns with different textures, gloss levels, or three-dimensional effects, but also meet customers' demands for personalized, high-end products. This allows companies to develop more creative and value-added products, thus gaining a competitive edge in the fierce market.

[0011] 3. The waste collection tank enables the centralized collection of waste materials and excess flocking generated during the printing and flocking processes. This not only greatly improves the cleanliness of the production site, reduces the wear and pollution of equipment caused by dust and debris, and lowers the workload of daily cleaning and maintenance, but also facilitates potential waste recycling, meets environmental protection requirements, and provides operators with a safer and more hygienic working environment.

Detailed Implementation

[0013] 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.

[0014] Combination Figure 1-4As shown, a PVC film printing and flocking integrated machine includes a support frame 1, a flocking device 2 on one side of the support frame 1, a printing device 3 on one side of the flocking device 2, a PVC film conveyor line on the support frame 1, and a printing device 3 including a Z-axis servo motor lifting device 31, a transverse servo motor moving device 32 on one side of the Z-axis servo motor lifting device 31, a pressing and fixing device 33 at the upper and lower ends of the transverse servo motor moving device 32, a scraping device 34 on one side of the transverse servo motor moving device 32, and a pressing and fixing device 33 including two fixing arms 331 in an opposing position. A first lifting cylinder 332 is provided at the upper end of each fixing arm 331, and a pressing and fixing frame 333 is provided at the output end of the first lifting cylinder 332. A pressing and fixing frame 333 is provided on the inner side wall of the pressing and fixing frame 333. The fixed locking plate 334, equipped with locking bolts 335, integrates the two core processes of printing and flocking into one machine. This eliminates the time spent on handling, positioning, and waiting in intermediate steps, greatly improving production efficiency and reducing production costs and labor input. The PVC film conveyor line enables automated and continuous transmission of the film from printing to flocking, reducing human intervention, operational difficulty, and errors caused by manual operation. During the printing process, two opposing fixed arms, in conjunction with a lifting cylinder and a downward pressing frame, firmly press and fix the PVC film onto the worktable. The lifting cylinder provides rapid, uniform, and stable downward pressure, effectively preventing the film from shifting, wrinkling, or deforming during printing, ensuring the clarity and accuracy of the printed pattern.

[0015] The scraping device 34 includes a fixed back plate 341. Two second lifting cylinders 342 are symmetrically arranged on one side of the fixed back plate 341. Each second lifting cylinder 342 has a guide rod 343 at its output end. A first scraper 344 and a second scraper 345 are arranged on one side of the lower end of each guide rod 343. The two second lifting cylinders 342 control the first scraper 344 and the second scraper 345 respectively. The two independent lifting cylinders control the raising and lowering of the first and second scrapers, meaning that the pressing and raising of each scraper can be controlled individually according to printing needs, improving the flexibility of the printing process. The independently controlled dual-scraper system allows for simultaneous printing... Different doctor blades are used during the process. For example, one doctor blade is used for pre-coating or base color printing, while another is used for detail or special effects printing, thus achieving more complex and refined printing effects. The guide rod ensures that the doctor blade remains vertically stable during lifting and lowering, avoiding wobbling and ensuring the uniformity and consistency of ink scraping, thereby improving printing quality. The cutting edges of both the first doctor blade 344 and the second doctor blade 345 are curved, with the curvature of the first doctor blade 344 being greater than that of the second doctor blade 345, to achieve different ink scraping effects. Compared to traditional right-angle doctor blades, the curved cutting edge can better control the rolling and transfer of ink, reducing ink smearing. The splashing and bubble generation make the printed pattern more delicate, uniform, and full. The first squeegee with a larger curvature (more blunt) may be suitable for scraping a thicker ink layer, achieving better coverage and smoothness, such as for underprinting or large-area solid color printing. The second squeegee with a smaller curvature (more sharp) may be suitable for scraping a thinner ink layer, achieving finer lines, textures, or special effects printing. By adjusting the use of different squeegee curvatures, areas with different ink thicknesses, gloss levels, or tactile textures can be achieved on the same product, giving the product a richer visual and tactile experience, increasing its added value and market competitiveness; Fixed backplate 341 The support frame 1 is also equipped with an ink storage tank 346, which is connected to the first doctor blade 344 and the second doctor blade 345 via a pipe. An ink flow control valve 347 is installed on the pipe to regulate the ink supply. The introduction of the ink flow control valve allows the operator to precisely adjust the amount of ink supplied to the doctor blade according to the printing process, ink type and printing effect requirements. This is crucial for controlling the color depth, ink thickness and uniformity of the printed matter. The support frame 1 is also equipped with a waste collection tank, which is located below the end of the PVC film conveyor line and is used to collect waste and excess flocking generated during the printing and flocking processes.

[0016] Working principle: When the PVC film is transferred to the worktable below the printing device, the Z-axis servo motor lifting device 31 is activated, precisely lowering the upper horizontal servo motor moving device 32 and the lower pressing and fixing device 33 above the film. The two opposing fixing arms 331 cooperate, and the first lifting cylinder 332 at their upper ends extends synchronously, driving the pressing and fixing frame 333 to move downward. The fixing locking plate 334 on the inner wall of the pressing and fixing frame 333 fixes the printing template with locking bolts 335. The stable downward pressure provided by the lifting cylinder effectively prevents the film from shifting, wrinkling or deforming during the printing process, ensuring the accuracy of printing. The horizontal servo motor moving device 32 drives the entire squeegee device 34 to move horizontally above the film, so that the selected squeegee evenly scrapes the ink across the screen and transfers it to the fixed PVC film, completing the pattern printing. The arc-shaped squeegee blade optimizes the rolling and transfer of ink, reduces splashing and bubbles, and makes the printing effect more delicate and full.
