Description

Technical Field

[0001] The present application relates to the technical field of printing devices, and specifically to a printing device for pharmaceutical packaging. Background Art

[0002] Pharmaceutical packaging refers to the general term for the process of using appropriate materials or containers and packaging technology to divide (fill), seal, package, label and other operations on semi-finished or finished pharmaceutical preparations, providing quality assurance, identification trademarks and instructions for drugs. According to the packaging level or function, it can be divided into inner packaging and outer packaging. Among them, outer packaging usually includes cartons, paper boxes, plastic bags, aluminum foil bags, etc., which are used to contain and protect inner packaging (such as medicine bottles, medicine boxes, etc.) and the drugs themselves;

[0003] During the outer packaging process, it is necessary to print the surface of the carton or paper box used for the outer packaging to provide necessary information on the use of the drug;

[0004] For example, patent publication number CN208993259U specifically discloses a fully automatic screen printing device. The device uses a motor to drive a roller to rotate, thereby transporting the substrate on the roller to between the printing fixed plate and the screen printing plate. Then, a third cylinder pushes the second scraper downward to apply a certain pressure to the ink area on the screen printing plate. The second cylinder pushes the first scraper upward to a suspended state. At the same time, the first cylinder drives the mounting table from right to left, causing the second scraper to move toward the right end of the screen printing plate. During the movement, the ink is squeezed by the scraper from the mesh of the image part to the substrate for printing;

[0005] However, during printing, the second scraper needs to be frequently scraped on the screen printing plate, which causes the scraper to wear easily. The worn scraper cannot ensure the uniform distribution of ink when scraping ink, resulting in color difference, spots or stripes on the printed product. Therefore, it needs to be replaced regularly. The current replacement method is mostly manual replacement. Manual replacement of the scraper requires stopping the production line, which will cause long interruptions in the production line. The increase in downtime will significantly reduce production efficiency.

[0006] Therefore, it is necessary to provide a printing device for medicine packaging to solve the above problems.

[0031] The ink scraping assembly 3 includes a first driving unit 31 provided on the workbench 1. A second driving unit 301 is mounted at the output end of the first driving unit 31. The second driving unit 301 can move up and down in the vertical direction. It should be noted that the first driving unit 31 is a prior art, such as the lifting slide rail device mentioned in the patent with the authorization announcement number CN211164743U, and will not be described in detail in this application.

[0032] At the same time, the second driving part 301 can be a translation mechanism driven by a hydraulic cylinder. When in use, a base can be installed at the output end of the first driving part 31, and a hydraulic cylinder can be installed on the base. At the same time, a fixed base 35 is installed at the output end of the hydraulic cylinder, and a track is installed on the base. The fixed base 35 is slidably arranged on the track, and then driven by the hydraulic cylinder, the fixed base 35 can move on the track;

[0033] At the same time, connecting plates 32 are installed at both ends of the base. When the second driving part 301 moves up and down, the connecting plates 32 are synchronously driven to move. Clamping plates 33 are fixedly installed on the two sets of connecting plates 32. Grooves 331 are opened inside the two sets of clamping plates 33. Printing frame plates 34 are slidably installed inside the two sets of grooves 331. The printing frame plates 34 are provided with a printing area to facilitate subsequent printing operations.

[0034] like Figure 2 As shown, multiple sets of screws 332 are threadedly mounted on the clamping plate 33, and a pressure plate (not shown) is fixedly mounted on one end of the screw 332 to facilitate screwing the screw 332 into the groove 331 to fix the printing frame 34;

[0035] At the same time, a first mounting platform 37 is fixedly mounted on one end of the fixed base 35 so that the fixed base 35 can synchronously drive the first mounting platform 37 to perform lifting and translation operations. At the same time, a cylinder 36 is fixedly mounted on the first mounting platform 37. A mounting plate 38 is fixedly mounted on the output end of the cylinder 36. The mounting plate 38 is slidably arranged inside the first mounting platform 37. A scraper 39 is detachably mounted on the end of the first mounting platform 37 away from the cylinder 36. So that under the drive of the cylinder 36, the mounting plate 38 drives the scraper 39 to perform lifting operations, and when the scraper 39 is lowered, it can abut against the printing frame 34.

[0036] At the same time, a printing assembly 4 is provided on the mounting table, and the printing assembly 4 is suitable for performing a printing operation on the packaging to be printed;

[0037] like Figure 3-Figure 4 As shown, the printing assembly 4 includes a second mounting platform 42 fixedly mounted on one side of the fixing base 35. An electric cylinder 41 is fixedly mounted on the second mounting platform 42. The electric cylinder 41 is located on one side of the air cylinder 36. A slide 43 is fixedly mounted on the output end of the electric cylinder 41. The slide 43 is slidably arranged in the second mounting platform 42 so that the slide 43 can be raised and lowered in the second mounting platform 42 under the drive of the electric cylinder 41. A switching box 44 is fixedly mounted on the bottom of the slide 43, and a motor 49 is fixedly mounted on the switching box 44.

[0038] like Figure 3 and Figure 6 As shown, a belt drive mechanism 411 is provided at the output end of the motor 49, and two sets of sliding plates 46 are fixedly mounted at both ends of the belt drive structure. At the same time, two sets of slide rails 47 are fixedly mounted on the switch box 44. The sliding plates 46 are slidably mounted on the slide rails 47, and the two sets of sliding plates 46 are arranged opposite to each other. At the same time, two sets of movable grooves 45 suitable for sliding of the sliding plates 46 are opened on the switch box 44.

[0039] Then, driven by the motor 49, the driving belt transmission mechanism 411 drives the two sets of sliding plates 46 to slide synchronously in the two sets of sliding grooves 45. Due to the relative arrangement of the sliding plates 46, the movement directions of the two sets of sliding plates 46 are opposite.

[0040] Continue to refer Figure 4 , a mounting seat 471 is fixedly mounted on both sets of sliding plates 46, and a jacket 48 is fixedly mounted on one side of both sets of mounting seats 471, and a scraper 410 is detachably mounted inside the jacket 48. When the mounting seat 471 moves, the two sets of scrapers 410 are driven to move relative to each other through the two sets of jackets 48, thereby realizing the position switching of the two sets of scrapers 410;

[0041] At the same time, the workbench 1 is provided with a bearing assembly 2 for placing the object to be printed;

[0042] As shown in Figure 1 and Figure 5 The bearing assembly 2 comprises a printing table 21 fixedly installed on the workbench 1, and a plurality of groups of air hole joints 22 are arranged on the printing table 21 to facilitate connection with external negative pressure equipment, so as to place the object to be printed on the printing table 21 for pneumatic adsorption;

[0043] As described above, before printing, ink is applied to one end of the printing frame plate 34, and the ink is located between the ink scraping plate 410 and the scraping plate 39. At this time, the scraping plate 39 abuts against the printing frame plate 34, and the ink scraping plate 410 is in a suspended state. The ink scraping assembly 3 drives the ink scraping plate 410 and the scraping plate 39 to move synchronously. At this time, the scraping plate 39 scrapes the ink to be uniformly distributed on the printing area of the printing frame plate 34. Then, the object to be printed is placed on the bearing assembly 2 for adsorption and fixation, and the printing frame plate 34 is moved downward.

[0044] At this time, the air cylinder 36 drives the scraping plate 39 to rise to be suspended, the electric cylinder 41 drives the ink scraping plate 410 to abut against the printing frame plate 34, the ink scraping assembly 3 drives the ink scraping plate 410 and the scraping plate 39 to move synchronously. During the movement of the ink scraping plate 410, the ink is extruded through the printing area and printed on the object to be printed. When continuous printing is required, the above steps are repeated. When the ink scraping plate 410 is worn after long-term use, the ink scraping plate 410 can be switched by the printing assembly 4.

[0045] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes.
