Description

Technical Field

[0001] This utility model relates to the field of product packaging technology, specifically to a packaging material printing equipment. Background Technology

[0002] Packaging materials refer to the materials used to manufacture packaging containers, packaging decoration, packaging printing, packaging transportation, etc., to meet the packaging requirements of products. They include major packaging materials such as metals, plastics, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, chemical fibers, and composite materials, as well as auxiliary materials such as strapping, decoration, and printing materials. In order to display product information, various patterns or texts need to be printed on packaging materials to facilitate consumers' understanding and purchase of products.

[0003] A search revealed that Chinese patent application CN 216659263U discloses a packaging material printing apparatus. This apparatus features a quick-drying mechanism located on the upper right side of the printing unit. The quick-drying mechanism is arc-shaped, with a stainless steel plate on its top. Inside, a heating plate and a silicone plate are installed. The heating plate is heated by electrodes, and the silicone plate transfers the heat to the stainless steel plate. The silicone plate has excellent thermal conductivity, allowing for rapid heat transfer. When the printed packaging material passes through the stainless steel plate, the heat enables the ink to dry quickly, reducing subsequent drying time.

[0004] However, the following technical problems still exist when implementing the above technical solutions: the printing spacing cannot be flexibly adjusted during the printing process; when different sizes or different thicknesses of the printed objects need to be printed, the printing spacing cannot be adjusted quickly and accurately; in addition, if the packaging material is placed directly on the printing area for printing, once dust or other impurities adhere to the surface of the packaging material, they will transfer and adhere to the printing cylinder after contacting it, which will affect the printing effect on the surface of the packaging material.

[0005] Therefore, the problem that this utility model urgently needs to solve is to provide a packaging material printing equipment that can flexibly adjust the printing spacing during use, improve printing efficiency, and clean the surface of packaging materials to meet diverse printing needs. Utility Model Content

When printing different sizes or objects with varying thicknesses, it is impossible to quickly and accurately adjust the printing spacing. Furthermore, when packaging materials are directly placed on the printing area for printing, dust and other impurities adhering to the surface of the packaging material will transfer and adhere to the printing cylinder, affecting the printing effect on the packaging material surface. Therefore, this utility model provides a packaging material printing device that allows for flexible adjustment of the printing spacing during use, improving printing efficiency, and also enabling the cleaning of the packaging material surface, thus meeting diverse printing needs.

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0028] Reference Figures 1-6As shown, a packaging material printing device includes: a printing device body 101, a printing inlet 102 on one side of the printing device body 101, a winding roller 103 rotatably disposed near the printing inlet 102 inside the printing device body 101, and a traction roller 112 rotatably disposed away from the printing inlet 102. A printing element is disposed inside the printing device body 101 between the winding roller 103 and the traction roller 112. A pressure roller 110, parallel to and cooperating with the printing element, is disposed on the printing device body 101 via a lifting adjustment mechanism 200 for printing packaging materials of different thicknesses. Multiple sets of carrier rollers 104 are rotatably disposed at intervals in front of the printing element inside the printing device body 101. A cleaning mechanism 300 is disposed between two sets of carrier rollers 104 inside the printing device body 101 for cleaning the surface of packaging materials of different thicknesses as the pressure roller 110 rises and falls.

[0029] In operation, the packaging material is fed into the printing equipment body 101 through the printing inlet 102. The material first passes over the winding roller 103, which provides initial guidance and tension, allowing the material to enter the subsequent processing stage with appropriate tension. Subsequently, the packaging material passes through multiple sets of support rollers 104, which support and guide the material forward, ensuring a stable material transport path. While the packaging material is passing between two sets of support rollers 104, the cleaning mechanism 300 cleans the material surface. Since the cleaning mechanism 300 is linked to the pressure roller 110, when the height of the pressure roller 110 is adjusted according to the thickness of the packaging material via the lifting adjustment mechanism 200, the cleaning mechanism 300 will also rise and fall accordingly to accommodate the cleaning needs of materials of different thicknesses. The cleaning mechanism 300 removes dust, impurities, etc., from the material surface, providing a clean surface for subsequent printing and ensuring print quality. The cleaned packaging material continues to be conveyed forward between the printed part and the pressure roller 110. The height of the pressure roller 110 is adjusted via the lifting adjustment mechanism 200 to create a suitable gap between it and the printed part, accommodating the printing needs of packaging materials of different thicknesses. The pressure roller 110 works in conjunction with the printed material to perform printing operations on the material surface, printing the required patterns, text, etc., onto the packaging material. After printing is completed, the traction roller 112 rotates, pulling the printed packaging material out from the printing equipment body 101, completing the entire printing process. The traction roller 112 provides a stable traction force, ensuring that the material moves at a uniform speed during the printing process and guaranteeing the consistency of the printing effect.

[0030] Reference Figures 2-5As shown, the lifting and adjusting mechanism 200 includes: a slide rod 203 that slides through the top wall of the printing equipment body 101; a mounting frame 204 that slides and engages with the side wall of the printing equipment body 101 is fixedly mounted on the bottom surface of the slide rod 203; the pressure roller 110 is rotatably mounted within the mounting frame 204; a limiting plate 205 is fixedly mounted at one end of the slide rod 203 that passes through the top wall of the printing equipment body 101; springs 206 are sleeved on the slide rod 203, with both ends abutting against the side wall of the limiting plate 205 and the side wall of the printing equipment body 101 respectively; and a driving component for driving the slide rod 203 to slide is provided on the printing equipment body 101. The driving component includes: a rotary motor 201 fixedly mounted on the top wall of the printing equipment body 101; the output shaft of the rotary motor 201 is horizontally positioned, and a cam 202 that contacts the limiting plate 205 is fixedly mounted at its top end.

[0031] In the above scheme, when it is necessary to adjust the height of the pressure roller 110 to accommodate packaging materials of different thicknesses, the rotary motor 201 is started, and the output shaft of the rotary motor 201 drives the cam 202 to rotate. As the cam 202 rotates, the change in its contour shape pushes the spring 206 and the slide rod 203 in contact with it. When the protruding part of the cam 202 contacts the limiting plate 205, it squeezes the spring 206, causing the spring 206 to compress and push the slide rod 203 to slide downwards. The slide rod 203 drives the mounting frame 204 and the pressure roller 110 to descend. When the protruding part of the cam 202 rotates away from the limiting plate 205, under the action of the spring 206's own elasticity, the spring 206 restores its deformation and pushes the slide rod 203 to slide upwards, causing the pressure roller 110 to rise. By controlling the rotation angle and speed of the rotary motor 201, the rotation of the cam 202 can be precisely controlled, thereby achieving precise adjustment of the lifting height and speed of the pressure roller 110.

[0032] Reference Figures 4-6 As shown, the cleaning mechanism 300 includes: a mounting plate 307 slidably disposed within the printing equipment body 101 via a guide rod 306; a second limiting groove 310 for sliding the guide rod 306 is provided on the inner sidewall of the printing equipment body 101 that is far apart from each other; a plurality of cleaning heads 308 that are fixed at intervals on the mounting plate 307 and contact the surface of the packaging material; and the mounting plate 307 is connected to the mounting frame 204 via a linkage to achieve synchronous lifting and lowering with the mounting frame 204 for cleaning packaging materials of different thicknesses.

[0033] In the above scheme, when the height of the pressure roller 110 is adjusted by the lifting adjustment mechanism 200, the linkage connected to the mounting frame 204 will move synchronously, causing the mounting plate 307 to slide along the second limiting groove 310 on the inner side wall of the printing equipment body 101 under the guidance of the guide rod 306. During the rising or falling of the mounting plate 307, the cleaning heads 308 fixed at intervals on it will move closer to or further away from the surface of the packaging material accordingly. During the conveying of the packaging material, the cleaning heads 308 contact the surface of the packaging material and clean away dust, impurities, etc. on the surface of the material through physical friction, ensuring that the surface of the packaging material is clean and providing a good foundation for subsequent printing. After the height of the pressure roller 110 is adjusted, the cleaning mechanism 300 also stabilizes in the corresponding position and continues to clean the passing packaging material.

[0034] Reference Figures 4-6 As shown, the linkage includes: a transmission rack 301 vertically fixed on the side wall of the mounting frame 204; a first limiting groove 309 for sliding the transmission rack 301 is provided on the side wall of the printing equipment body 101; a gear 302 rotatably meshing with the transmission rack 301 is provided on the outer side wall of the printing equipment body 101; a drive rod 304 is slidably provided on the printing equipment body 101; a guide groove 305 for sliding the guide rod 306 is provided in the drive rod 304; and a rack 303 meshing with the gear 302 is fixed on the bottom surface of the drive rod 304.

[0035] In the above scheme, when the mounting frame 204 in the lifting adjustment mechanism 200 rises and falls with the slide rod 203, the transmission rack 301 fixed on the side wall of the mounting frame 204 slides in the first limiting groove 309. The movement of the transmission rack 301 drives the gear 302 meshing with it to rotate. When the gear 302 rotates, it meshes with the rack 303 on the bottom surface of the drive rod 304, thereby driving the inclined drive rod 304 to slide on the printing equipment body 101. Since the drive rod 304 has a guide groove 305 for the guide rod 306 to slide, the sliding of the drive rod 304 will drive the guide rod 306 to move through the guide groove 305, thereby causing the mounting plate 307 to rise and fall along the second limiting groove 310, realizing the synchronous rise and fall of the cleaning head 308 and the mounting frame 204. In the whole process, through the meshing transmission of the gear and rack, the lifting movement of the mounting frame 204 is accurately transmitted to the cleaning mechanism 300, ensuring that the cleaning mechanism 300 can respond to the change in the height of the pressure roller 110 in a timely manner.

[0036] Reference Figures 4-6As shown, the printed material includes: an ink cartridge 105 fixedly disposed within the printing equipment body 101 and located between the winding roller 103 and the traction roller 112; both the printing equipment body 101 and the ink cartridge 105 are provided with ink inlets 113; and a printing roller 106 for printing on packaging materials is rotatably disposed within the ink cartridge 105; the pressure roller 110 is parallel to and cooperates with the printing roller 106.

[0037] In the above scheme, ink is injected into the ink cartridge 105 through the ink inlet 113 on the printing equipment body 101 and the ink cartridge 105. Packaging material enters from the printing inlet 102, passes sequentially through the winding roller 103 and the support roller 104, and reaches between the printing roller 106 and the pressure roller 110. The printing roller 106 rotates inside the ink cartridge 105, its surface continuously absorbing ink from the cartridge. When the packaging material is conveyed between the printing roller 106 and the pressure roller 110, the pressure roller 110 presses the packaging material firmly onto the printing roller 106. As the printing roller 106 rotates, ink is transferred to the surface of the packaging material, thus completing the printing process. Afterwards, the printed packaging material continues to be conveyed forward under the traction of the traction roller 112.

[0038] Reference Figures 4-6 As shown, an ink transfer roller 107 is fixedly provided on the inner wall of the printing equipment body 101, and a scraper 109 is fixedly provided on the circumferential surface of the ink transfer roller 107. The scraper 109 is in contact with the surface of the printing roller 106, and a guide plate 108 is inclinedly provided on the side of the ink box 105 near the ink transfer roller 107.

[0039] In the above scheme, during the ink printing process, the scraper 109 fixed on the circumferential surface of the ink transfer roller 107 contacts the surface of the printing roller 106. The scraper 109 scrapes off the excess ink on the surface of the printing roller 106, so that the ink layer thickness on the surface of the printing roller 106 is uniform. Under the action of gravity, the scraped ink flows along the inclined guide plate 108 to the ink box 105.

[0040] Reference Figure 4 As shown, a drying component 111 for drying the printed packaging material is fixedly provided inside the printing equipment body 101 between the printing roller 106 and the traction roller 112.

[0041] In the above scheme, after the packaging material is printed between the printing roller 106 and the pressure roller 110, it continues to be conveyed forward to the drying unit 111. The drying unit 111 starts working to dry the printed packaging material, accelerating the drying speed of the ink on the surface of the packaging material.

[0042] In summary, the packaging material printing equipment provided by this utility model, during use, feeds the packaging material into the equipment through the printing inlet 102 on one side of the printing equipment body 101. The packaging material first passes around the winding roller 103 near the printing inlet 102, which provides initial guidance and tension to maintain appropriate tension. Subsequently, the packaging material passes sequentially through multiple sets of spaced rotating support rollers 104 positioned in front of the printing workpiece. The support rollers 104 support and drive the material forward smoothly, preparing for subsequent cleaning and printing processes. Based on the thickness of the packaging material, the drive component in the lifting adjustment mechanism 200 is activated. The rotary motor 201 drives the cam 202 to rotate, and the cam 202 pushes the spring 206 and the slide bar 203, causing the slide bar 203 to slide on the top wall of the printing equipment body 101, thereby driving the mounting frame 204 and the pressure roller 110 to rise and fall. Simultaneously, the transmission rack 301 on the side wall of the mounting frame 204 slides within the first limiting groove 309, driving the gear 302 to rotate. The gear 302 meshes with the rack 303 on the bottom surface of the drive rod 304, driving the inclined drive rod 304 to slide. The drive rod 304 drives the guide rod 306 to move through the guide groove 305, causing the mounting plate 307 to rise and fall along the second limiting groove 310, thus achieving synchronous rising and falling of the cleaning mechanism 300 and the pressure roller 110. When the packaging material passes between the two sets of bearing rollers 104, the cleaning head 308 on the mounting plate 307 contacts the material surface. The cleaning head 308 removes dust and impurities from the material surface through physical friction and other methods, ensuring the cleanliness of the material surface. Ink is injected into the ink cartridge 105 through the ink inlet 113 on the printing equipment body 101 and the ink cartridge 105. The printing roller 106 rotates and picks up ink for printing. Simultaneously, the scraper 109 on the circumferential surface of the ink transfer roller 107 contacts the surface of the printing roller 106, scraping away excess ink to ensure a uniform ink layer thickness. The cleaned packaging material continues to be conveyed between the printing roller 106 and the pressure roller 110. The pressure roller 110, adjusted to the appropriate height, presses the packaging material firmly onto the printing roller 106. As the printing roller 106 rotates, ink is transferred to the surface of the packaging material, completing the printing process. The printed packaging material continues to be conveyed forward to the drying unit 111 located between the printing roller 106 and the traction roller 112. The drying unit 111 is activated, using heating and blowing to dry the printed packaging material, accelerating ink drying. After drying, the traction roller 112 rotates, pulling the dried packaging material out of the printing equipment body 101, completing the entire printing process.
