Description

Technical Field

[0001] The present invention relates to the technical field of decorative printing, and in particular to a decorative printing method and equipment for executing the method. Background Art

[0002] Decorative printing methods mainly include the following common processes: hot stamping / silvering, spot UV, embossing / embossing, hollowing / die-cutting, relief effect, frosted UV, etc. These decorative printing methods not only enhance the visual effect and tactile feel of printed products, but also allow the appropriate process to be selected according to specific needs to achieve the desired decorative effect.

[0003] The above-mentioned decoration scheme is mainly aimed at the decorative printing of soft printed materials such as paper, cloth and film. For some hard and posted materials, such as decorative wall panels, curtain wall panels, etc., once the panels of such materials are constructed and formed, their decorative style is difficult to change at will. Some people with higher artistic pursuits ask professional painters to paint on the panels of such materials in order to obtain decorative wall panels with ideal pictures.

[0004] However, for some people who have limited budgets or want to temporarily change the decoration style, the cost of hiring a painter is relatively high, and it is difficult to achieve their own expectations, and they cannot change the decoration style at any time according to their preferences. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a decoration printing method and an apparatus for performing the method.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: A decorative printing method comprising the following steps: S1. Use special printing equipment for decorative wall panels to paste decorative films with specific shapes on the decorative surface of the equipment as needed, and ensure that the decorative films are flat and fixed; S2. Using the decorative film adjustment mechanism, adjust the decorative film to be in close contact with the surface of the decorative panel, and using the pigment delivery assembly to spray pigment onto the area of ​​the decorative film below the specific shape; S3. The paint on the decorative film is scraped upward by a paint scraping mechanism. When the paint passes through a specific shape area on the decorative film, the paint is scraped flat by the paint scraping mechanism, and the excess paint is scraped to the area of ​​the decorative film above the specific shape; S4. Control the paint scraping mechanism and the decorative film adjusting mechanism to reset in sequence, remove the decorative film, and then replace the decorative film according to different decorative styles.

[0007] By adopting the above technical solution, the special printing equipment for decorative wall panels is moved in front of the decorative wall panels that need decorative printing, and the decorative film is posted according to user needs. The paint delivery component can spray paint on the area of ​​the decorative film under the specific shape, and then the paint on the decorative film is evenly scraped in the specific shape area through the paint leveling mechanism, thereby meeting the needs of decorative printing patterns on the decorative panels and improving the user experience.

[0008] Furthermore, it includes a base and a mounting frame fixed to one side of the base, the mounting frame is provided with a mounting frame for installing the decorative film, the mounting frames are provided with multiple and respectively correspond to the decorative plates of the decorative patterns to be printed, one side of the mounting frame is provided with a mounting block for installing the paint delivery component, the number of the mounting blocks is equal to the number of the mounting frames and the positions correspond one to one, and the base is provided with a paint scraping mechanism for scraping the paint sprayed by the paint delivery component onto the decorative film into a specific modeling area.

[0009] Furthermore, the edges on both sides of the decorative film are bent to fit the outer wall at the corner of the mounting frame, and the four corners of the mounting frame are provided with fixing components for fixing the decorative film. The fixing components include a screw fixed to the outer wall of the mounting frame near the corner of the mounting frame, a nut sleeved on the screw and threadedly connected, and a clamping plate sleeved on the screw and clearance-fitted, and the clamping plate is located between the nut and the side wall of the mounting frame.

[0010] By adopting the above technical solution, after loosening the nut, the distance between the clamping plate and the outer wall of the mounting frame can be adjusted. After a decorative film with a suitable shape is posted on the side of the mounting frame away from the mounting block, the edges on both sides of the decorative film are bent until they fit the outer wall at the corner of the mounting frame. After tightening the nut, the decorative film can be fixed by the compression between the clamping plate and the mounting frame, so that the paint leveling mechanism can level the paint sprayed onto the decorative film by the paint delivery assembly within a specific shape area.

[0011] Furthermore, the clamping plate is integrally formed with an arc-shaped ridge on the side close to the mounting frame, the outer wall of the mounting frame is provided with an arc-shaped groove that engages with the arc-shaped ridge, a circular hole is provided through the clamping plate, and a sleeve is fixed on the side wall of the clamping plate away from the mounting frame near the circular hole, and a first spring is fixed between the inner wall of the sleeve away from the mounting frame and the outer wall of the mounting frame.

[0012] By adopting the above technical solution, after loosening the nut, the clamping plate pops open under the elastic force of the first spring, eliminating the tedious operation of the staff to manually adjust the position of the clamping plate. The arc-shaped convex strips on the clamping plate cooperate with the arc-shaped grooves on the mounting frame to press the decorative film, thereby enhancing the stability of the decorative film during the fixing process.

[0013] Furthermore, the paint scraping mechanism includes a scraper assembly, which includes a hollow sleeve fixed to the side wall of the mounting block close to the decorative film, a connecting sleeve slidingly engaged with the inner wall of the hollow sleeve, a scraper block fixed to the side wall of the connecting sleeve away from the mounting block and pressed against the side wall of the decorative film close to the mounting block, and a second spring fixed between the scraper block and the inner wall of the hollow sleeve. The paint scraping mechanism also includes a driving assembly for driving the mounting block to move obliquely upward toward the side close to the mounting frame or obliquely downward away from the mounting frame.

[0014] By adopting this technical solution, when the drive assembly drives the mounting block to move upward toward the mounting frame, the scraper block, under the action of the second spring, can maintain contact with the decorative film. As the mounting block continues to move, the scraper block gradually completes the paint scraping action. When the drive assembly drives the mounting block to move downward toward the mounting frame, the scraper block gradually moves away from the decorative film, making it easier for workers to replace the decorative film.

[0015] Furthermore, the driving assembly includes a guide rod fixed to the top of the base, a threaded rod rotatably installed on the top of the base, a movable plate jointly provided on the threaded rod and the guide rod, a connecting rod fixed on the guide rod, a cross rod fixed on the connecting rod and parallel to the movable plate, a driven gear fixedly sleeved on the threaded rod, a motor fixed to the top of the base, and a driving gear fixed to the output end of the motor and meshing with the driven gear, the threaded rod passes through the movable plate and is threadedly connected, the guide rod passes through the movable plate and is clearance-fitted, the movable plate and multiple mounting blocks in the same row are all slidably fitted with slide rails, and the mounting blocks slide toward or away from the mounting frame under the action of the slide rails, and multiple mounting blocks in the same row are all penetrated by an oblique through hole slidably fitted with the cross rod, and the distance between the oblique through hole and the threaded rod gradually increases from bottom to top.

[0016] By adopting the above technical solution, the motor drives the driving gear to rotate after working, so that the driven gear meshing with it and the threaded rod fixed to the driven gear both rotate. Since the threaded rod is threadedly connected to the movable plate, the guide rod and the movable plate are clearance-matched, so that the movable plate can be raised and lowered. Since the oblique through holes on multiple mounting blocks in the same row are slidingly matched with the cross bar, the cross bar is fixed on the connecting rod, so that the mounting block can move upward in an inclined vertical direction. During this process, the scraping block can be kept tightly against the decorative film under the action of the second spring, and gradually completes the scraping action of the pigment on the surface of the decorative film, and finally completes the printing operation of the decorative pattern on the surface of the decorative wall panel.

[0017] The cam is secured to the side panel that is located adjacent to the guide rail and has a first end secured thereto so that the cam can move relative to the guide rail when the cam is in the forward position.

[0018] Furthermore, the column linkage assembly includes an electric push rod fixed on the side wall of the mounting frame, a connecting plate fixed to the push rod end of the electric push rod, a rack fixed to the top of the connecting plate, and a transmission gear fixedly sleeved on the threaded shaft and meshing with the rack. The number of the transmission gears is equal to the number of the threaded shafts and their positions correspond one to one.

[0019] By adopting the above technical solution, when the electric push rod works and drives the connecting plate to move upward, the rack drives the transmission gear, the threaded shaft fixed to the transmission gear, the synchronous wheel fixed to the threaded shaft, and the synchronous belt engaged with the synchronous wheel to rotate, so that the threaded shafts in each row and column rotate synchronously. Since the threaded shaft is threadedly connected to the first L-shaped rod, the guide rod slides with the second L-shaped rod, and the first L-shaped rod and the second L-shaped rod are both fixed to the mounting frame, so that the mounting frame moves toward or away from the decorative wall panel that needs decorative printing, so as to control the decorative films on multiple mounting frames to be close to the decorative wall panel, so as to facilitate the subsequent pigment delivery component to cooperate with the pigment scraping mechanism and complete the printing of the decorative pattern.

[0020] Furthermore, the slide rail is a U-shaped rod structure, both ends of the slide rail are fixed to the side wall of the mounting block away from the mounting frame, and the inner top wall and inner bottom wall of the slide rail are slidably matched with the movable plate.

[0021] Furthermore, the thickness of the first L-shaped rod and the thickness of the second L-shaped rod are both smaller than the distance between the upper inner surface of the synchronous belt and the lower inner top surface of the synchronous belt.

[0022] In summary, the present invention has the following beneficial effects: 1. In this application, a special printing device for decorative wall panels is moved in front of the decorative wall panels that need decorative printing, and a decorative film is pasted according to user needs. The pigment delivery component can spray pigment to the area of ​​the decorative film below the specific shape. Then, the pigment on the decorative film is evenly scraped in the specific shape area by the pigment leveling mechanism, thereby completing the decorative printing pattern requirements of the decorative panel and improving the user experience. 2. In this application, when the drive assembly drives the mounting block to move upward toward the side close to the mounting frame, the scraper block can be kept in contact with the decorative film under the action of the second spring. As the mounting block continues to move, the scraper block gradually completes the scraping action of the paint. When the drive assembly drives the mounting block to move downward toward the side away from the mounting frame, the scraper block gradually moves away from the decorative film, allowing staff to replace the decorative film. 3. In the present application, after the motor works, it drives the driving gear to rotate, thereby causing the driven gear meshing with it and the threaded rod fixed to the driven gear to rotate. Since the threaded rod is threadedly connected to the movable plate, the guide rod and the movable plate are clearance-matched, thereby allowing the movable plate to be raised and lowered. Since the oblique through holes on multiple mounting blocks in the same row are slidingly matched with the cross bar, the cross bar is fixed on the connecting rod, thereby allowing the mounting blocks to move upward in an inclined vertical direction. During this process, the scraper block can be kept tightly against the decorative film under the action of the second spring, and gradually completes the scraping action of the pigment on the surface of the decorative film, and finally completes the printing operation of the decorative pattern on the surface of the decorative wall panel.

[0028] This embodiment also discloses a device for executing the above-mentioned decorative printing method, including a base 1 and a mounting frame 2 fixed to one side of the base 1, the mounting frame 2 is provided with a mounting frame 3 for mounting a decorative film 31, and the mounting frame 3 is provided with multiple and respectively corresponds to the decorative plate of the decorative pattern to be printed, and one side of the mounting frame 2 is provided with a mounting block 4 for mounting a pigment delivery component, the number of the mounting blocks 4 is equal to the number of the mounting frames 3 and the positions correspond one to one, and the base 1 is provided with a pigment scraping mechanism 5 for scraping the pigment sprayed by the pigment delivery component onto the decorative film 31 into a specific modeling area.

[0029] The edges on both sides of the decorative film 31 are bent to fit the outer wall at the corner of the mounting frame 3. The four corners of the mounting frame 3 are provided with fixing components 6 for fixing the decorative film 31. The fixing components 6 include a screw 61 fixed to the outer wall of the mounting frame 3 near the corner of the mounting frame 3, a nut 62 sleeved on the screw 61 and threadedly connected, and a clamping plate 63 sleeved on the screw 61 and clearance-fitted. The clamping plate 63 is located between the nut 62 and the side wall of the mounting frame 3.

[0030] After loosening the nut 62, the distance between the pressing plate 63 and the outer wall of the mounting frame 3 can be adjusted. After a decorative film 31 with a suitable shape is posted on the side of the mounting frame 3 away from the mounting block 4, the edges on both sides of the decorative film 31 are bent until they fit the outer wall at the corner of the mounting frame 3. After tightening the nut 62, the decorative film 31 can be fixed by the compression between the pressing plate 63 and the mounting frame 3, so that the paint leveling mechanism 5 can level the paint sprayed onto the decorative film 31 by the paint delivery assembly within a specific shape area.

[0032] After loosening the nut 62, the clamping plate 63 pops open under the elastic force of the first spring 331, eliminating the tedious operation of the staff manually adjusting the position of the clamping plate 63. The arc-shaped ridge 631 on the clamping plate 63 cooperates with the arc-shaped groove 32 on the mounting frame 3 and presses the decorative film 31, thereby enhancing the stability of the decorative film 31 during the fixing process.

[0033] The paint scraping mechanism 5 includes a scraper assembly 51, which includes a hollow sleeve 511 fixed to the side wall of the mounting block 4 close to the decorative film 31, a connecting sleeve 512 slidingly engaged with the inner wall of the hollow sleeve 511, a scraper block 513 fixed to the side wall of the connecting sleeve 512 away from the mounting block 4 and pressed against the side wall of the decorative film 31 close to the mounting block 4, and a second spring 514 fixed between the scraper block 513 and the inner wall of the hollow sleeve 511. The paint scraping mechanism 5 also includes a driving assembly 52 for driving the mounting block 4 to move obliquely upward toward the side close to the mounting frame 3 or obliquely downward away from the mounting frame 3.

[0034] When the drive assembly 52 drives the mounting block 4 to move upwardly and at an angle toward the mounting frame 3, the scraper block 513, under the action of the second spring 514, can maintain contact with the decorative film 31. As the mounting block 4 continues to move, the scraper block 513 gradually completes the scraping of the paint. When the drive assembly 52 drives the mounting block 4 to move downwardly and at an angle away from the mounting frame 3, the scraper block 513 gradually moves away from the decorative film 31, allowing staff to replace the decorative film 31.

[0035] The driving assembly 52 includes a guide rod 521 fixed to the top of the base 1, a threaded rod 522 rotatably mounted on the top of the base 1, a movable plate 523 jointly provided on the threaded rod 522 and the guide rod 521, a connecting rod 524 fixed to the guide rod 521, a cross bar 525 fixed to the connecting rod 524 and parallel to the movable plate 523, a driven gear 526 fixedly sleeved on the threaded rod 522, a motor 527 fixed to the top of the base 1, and a driving gear 528 fixed to the output end of the motor 527 and meshing with the driven gear 526.

The inner top wall and the inner bottom wall of the slide rail 8 are slidingly fitted with the movable plate 523.) The mounting block 4 slides toward or away from the mounting frame 3 under the action of the slide rail 8. The multiple mounting blocks 4 in the same row are all penetrated by an oblique through hole 41 that is slidingly fitted with the crossbar 525. The distance between the oblique through hole 41 and the threaded rod 522 gradually increases from bottom to top.

[0036] After the motor 527 works, it drives the driving gear 528 to rotate, so that the driven gear 526 meshing with it and the threaded rod 522 fixed to the driven gear 526 both rotate. Since the threaded rod 522 is threadedly connected to the movable plate 523, the guide rod 521 and the movable plate 523 are clearance-matched, so that the movable plate 523 can be raised and lowered.

The control mechanism 7 includes a row linkage assembly 71, which includes a threaded shaft 711 rotatably mounted on the mounting frame 2, a first L-shaped rod 712 fixed to the side wall of the mounting frame 3 close to the mounting block 4 and close to the position of the threaded shaft 711, a guide rod 713 fixed to the side wall of the mounting frame 2 and parallel to the threaded shaft 711, a second L-shaped rod 714 fixed to the side wall of the mounting frame 3 close to the mounting block 4 and close to the position of the guide rod 713, and a second L-shaped rod 715 fixedly sleeved on the threaded shaft 711. The synchronous wheel 715 on the threaded shaft 711 and the threaded shaft 711 extend through the first L-shaped rod 712 and are threadedly connected thereto. The guide rod 713 extends through the second L-shaped rod 714 and is slidably engaged therewith. Three second L-shaped rods 714 and guide rods 713 are provided for each mounting frame 3. The first L-shaped rod 712 and the three second L-shaped rods 714 are located at the four corners of the mounting frame 3. The row linkage assembly 71 also includes a synchronous belt 716 that meshes with the synchronous wheels 715 corresponding to the other threaded shafts 711 in the same row. The control mechanism 7 also includes a row linkage assembly 72 for driving the rotation of the multiple threaded shafts 711 in the same row. In this embodiment, the thickness of the first L-shaped rod 712 and the thickness of the second L-shaped rod 714 are both less than the distance between the upper inner surface of the synchronous belt 716 and the lower inner top surface of the synchronous belt 716.

[0038] The column linkage assembly 72 includes an electric push rod 721 fixed to the side wall of the mounting frame 2, a connecting plate 722 fixed to the push rod end of the electric push rod 721, a rack 723 fixed to the top of the connecting plate 722, and a transmission gear 724 fixedly sleeved on the threaded shaft 711 and meshing with the rack 723. The number of the transmission gears 724 is equal to the number of the threaded shafts 711 and their positions correspond one to one.

[0039] When the electric push rod 721 works and drives the connecting plate 722 to move upward, the rack 723 drives the transmission gear 724, the threaded shaft 711 fixed to the transmission gear 724, the synchronous wheel 715 fixed to the threaded shaft 711, and the synchronous belt 716 engaged with the synchronous wheel 715 to rotate, so that the threaded shafts 711 in each row and column rotate synchronously. Since the threaded shaft 711 is threadedly connected to the first L-shaped rod 712, the guide rod 713 slides with the second L-shaped rod 714, and the first L-shaped rod 712 and the second L-shaped rod 714 are both fixed to the mounting frame 3, so that the mounting frame 3 moves toward or away from the decorative wallboard that needs decorative printing, so as to control the decorative films 31 on multiple mounting frames 3 to be close to the decorative wallboard, so that the subsequent pigment delivery component and the pigment scraping mechanism 5 cooperate to complete the printing of the decorative pattern.
