Description

Technical Field

[0001] This invention relates to the field of printing and processing technology, and more specifically, to an automatic embossing printing device. Background Technology

[0002] In many fields such as printing and packaging, cultural and creative products, and food packaging, automatic embossing printing equipment is a core processing equipment for enhancing product added value. It can combine printed patterns with three-dimensional embossing effects, giving products a unique visual texture and tactile experience.

[0003] Most commercially available automatic embossing printing equipment employs a separate, independent operation model for printing and embossing. According to authorization announcement number CN223685589U, an automatic edge trimming device for printing is disclosed, comprising two upright plates and printed material. An adjustment mechanism is located in the middle of one side of the two upright plates facing each other. Extrusion mechanisms are located on the lower left and right sides of the upright plates, and conveying mechanisms are located on the upper left and right sides of the upright plates. In this automatic edge trimming device, a servo motor drives a bidirectional threaded rod to rotate, causing the support plates to move closer or further apart, thereby adjusting the distance between the two cutting blades. This allows for arbitrary edge trimming of the printed material as needed. Two reduction motors drive the shaft to rotate the auger blades, which in turn move the printed material to the right via rubber rollers. The auger blades flatten the printed material to the front and back sides. The spring force on the left side is less than that on the right side, resulting in greater pressure from the right extrusion roller on the printed material compared to the left, keeping the printed material taut and improving the trimming effect.

[0004] Currently, most embossing and printing processes are operated with independent equipment. This not only increases the distance the substrate is transported, but also easily causes continuous substrates to shift during transport. This reduces the registration accuracy of subsequent embossing and printing processes, resulting in problems such as pattern misalignment and embossing deviation, which affects the consistency of the product's appearance.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example Reference Figures 1-7 The present invention provides a technical solution: an automatic embossing printing device, including a guiding mechanism 1, on which a printing mechanism 2 and an embossing mechanism 3 are respectively provided. The guiding mechanism 1 is used to accurately guide and stably transport the continuously conveyed substrate 15 to be processed. The printing mechanism 2 is responsible for printing ink patterns on the surface of the substrate. The embossing mechanism 3 is used to press the required three-dimensional texture on the surface of the printed substrate. The guiding mechanism 1 includes a table 10 and two guide frames 11 of the same size. The guide frames 11 are symmetrically fixed on both sides of the upper end of the table 10. Bearings 12 are symmetrically fixed through both sides of the guide frames 11 at the upper and lower positions. The same shaft 13 is interference-fitted on the inner ring wall of the two bearings 12 located on the same horizontal plane. The surface of the shaft 13 is fixedly sleeved with a guide roller 14. The substrate 15 to be processed is rolled and conveyed between the two guide rollers 14 distributed at the upper and lower positions. A guide table 110 is also fixedly installed on the surface of the table 10. The substrate 15 to be processed is slidably attached to the guide table 110. The guide table 110 provides a flat support plane for the substrate 15 to be processed. With the clamping and conveying of the upper and lower guide rollers 14, the stability of the material position in the printing and embossing area is ensured. Two shafts 13 are respectively fixedly mounted with a drive block 16 and a linkage block 17 at their outer ends. A drive gear 18 is fixedly sleeved on the surface of the drive block 16, and a linkage gear 19 is fixedly sleeved on the surface of the linkage block 17. The linkage gear 19 and the drive gear 18 are meshed and driven together. A motor 111 is fixedly mounted on one side of the guide frame 11 via a bracket. The motor 111 has a drive shaft inside, and the end of the drive shaft is connected to the shaft 13 via a coupling. When the motor 111 is powered on, it drives the shaft 13 connected to it to rotate. The drive gear 18 on the shaft 13 drives the linkage gear 19 meshing with it to rotate in the opposite direction, so that the upper and lower guide rollers 14 can rotate synchronously and in opposite directions, and the substrate 15 to be processed is smoothly conveyed forward.

[0022] The printing mechanism 2 includes a frame 20, with servo cylinders 21 symmetrically fixed through the upper end of the frame 20. The servo cylinder 21 has a piston rod for driving inside, and a lifting plate 22 is fixedly installed at the end of the piston rod. The vertical position of the lifting plate 22 can be controlled by extending and retracting the piston rod of the servo cylinder 21.

[0023] The frame 20 has a built-in hole 23 in the middle and a built-in hole 24 in the center of the lifting plate 22. The built-in hole 24 is connected to the built-in hole 23. The two built-in holes provide clearance for the lifting and lowering movement of the ink cartridge 2001 and related components.

[0024] Among them, servo cylinders 25 are symmetrically installed on the upper end of the table 10. The servo cylinders 25 have piston rods 2 for extension and retraction inside, and printing plate 27 is fixedly installed at the end of piston rod 2. The printing plate 27 is located below the lifting plate 22. The printing plate 27 is used as a back pressure support during printing to ensure that the substrate 15 being processed is in close contact with the printing roller 2003.

[0025] Among them, a linear guide rail assembly is symmetrically installed at the lower end of the lifting plate 22. The linear guide rail assembly includes a slide rail 201, a slide base 202, and an anti-detachment block 203. The slide rail 201 is symmetrically installed and fixed along the lower end of the lifting plate 22. Anti-detachment blocks 203 are symmetrically fixed at both ends of the slide rail 201. The slide base 202 is slidably disposed on the surface of the slide rail 201. By sliding the slide base 202 based on the slide rail 201, the printing roller 2003 can cooperate with the printing plate 27 to perform printing processing. The anti-detachment block 203 can prevent the slide base 202 from slipping.

[0026] Ink cartridges 2001 are fixedly mounted on the lower ends of the two slides 202. A roller 2002 is rotatably mounted inside the ink cartridge 2001. A printing roller 2003 is fixedly sleeved on the surface of the roller 2002. The surface of the printing roller 2003 is in close contact with the inner wall of the opening of the ink cartridge 2001. A motor 2004 is fixedly mounted on the outer end of the ink cartridge 2001 through a bracket. A rotating shaft 2004 is provided inside the motor 2004 for driving. The end of the rotating shaft 2004 is connected to the roller 2002 through a coupling. After the motor 2004 is powered on, the roller 2002 can be rotated, and the printing roller 2003 can rotate based on the opening of the ink cartridge 2001. During the rotation, the ink in the ink cartridge 2001 can be carried out for roller printing.

[0027] The ink cartridge 2001 is equipped with an ink pump 2005 fixedly mounted on its upper end via a bracket. The discharge end flange of the ink pump 2005 is connected to a delivery pipe 2007. The other end of the delivery pipe 2007 passes through the interior of the ink cartridge 2001. A level gauge 2006 is also embedded in the upper end of the ink cartridge 2001. The inlet end of the ink pump 2005 can be connected to an external ink container via a pipe for ink supply and delivery. The level gauge 2006 is used to monitor the ink level in real time to prevent ink shortage.

[0028] The embossing mechanism 3 includes a side frame 30. The side frame 30 is also fixedly installed on the upper end of the table 10. A servo cylinder 31 is symmetrically fixed through the upper end of the side frame 30. The servo cylinder 31 has a rotating shaft 3 for driving inside. A support frame 32 is fixedly installed at the end of the rotating shaft 3. The support frame 32 can be driven to move up and down as a whole by extending and retracting the piston rod of the servo cylinder 31.

[0029] The support frame 32 has bearings 33 embedded and fixed on both sides. The inner ring walls of the two bearings 33 are fitted with the same shaft 34. The support frame 32 is fixedly mounted with a bracket. The motor 35 is equipped with a rotating shaft for driving. The end of the rotating shaft is connected to the shaft 34 through a coupling. When the motor 35 is powered on, the rotating shaft can rotate, which will cause the shaft 34 to move in conjunction and drive the embossing roller 301 to roll and form patterns.

[0030] The shaft 34 has a fixedly fitted embossing roller 301. Several heating elements 302 are embedded inside the embossing roller 301. The ends of the heating elements 302 are connected to power transmission lines 303. The shaft 34 has an inner cavity 304. An electric slip ring 305 is fixedly installed on the outside of the support frame 32 by a bracket. The electric slip ring 305 has an inner core for power transmission. The inner core is fixed to the inner wall of the inner cavity 304 and is connected to the power transmission lines 303. When the embossing roller 301 rotates, the electric slip ring 305 provides a stable power input to the heating elements 302 inside. After the heating elements 302 heat up, the surface of the embossing roller 301 is heated evenly, thereby achieving hot pressing during the pressing of the texture and improving the clarity and durability of the embossing.

[0031] In practice After the equipment is started, the substrate 15 to be processed is fed between the upper and lower guide rollers 14. The guide frames 11, which are symmetrically fixed on both sides of the upper end of the table 10, support the shaft 13 through the bearing 12, so that the guide rollers 14 remain parallel. After the motor 111 is powered on, it drives one of the shafts 13 to rotate. The drive block 16 at the outer end of the shaft 13 drives the drive gear 18 to rotate. The drive gear 18 meshes with the linkage gear 19 on the linkage block 17, so that the upper and lower shafts 13 rotate synchronously in opposite directions. The upper and lower guide rollers 14 are thus clamped and rolled in opposite directions, and the substrate 15 to be processed is smoothly conveyed forward. At the same time, the guide table 110 fixed on the surface of the table 10 slides and fits against the substrate 15 to provide a flat support plane for the substrate, ensuring that the substrate does not deviate or shake when entering the subsequent processing area, thereby achieving continuous guidance and stable conveying. When the substrate 15 is conveyed above the printing plate 27, the second servo cylinder 25 drives the second piston rod to push the printing plate 27 upward, so that the substrate 15 is in close contact with the printing roller 2003 above. The first servo cylinder 21 drives the first piston rod to drive the lifting plate 22 to descend. The ink box 2001, which is connected to the lower end of the lifting plate 22 through the slide rail 201 and the slide seat 202, descends accordingly. The second motor 2004 drives the roller shaft 2002 to rotate, so that the printing roller 2003 rotates tightly against the inner wall of the opening of the ink box 2001, bringing out the ink inside the ink box 2001. The ink pump 2005 replenishes ink to the ink box 2001 through the delivery pipe 2007. The liquid level gauge 2006 monitors the liquid level in real time to prevent ink shortage. The slide seat 202 slides horizontally along the slide rail 201, driving the printing roller 2003 to roll and move on the surface of the substrate 15. With the back pressure support of the printing plate 27, accurate ink pattern printing is completed. After printing, the substrate 15 is continued to be conveyed to the bottom of the embossing roller 301. The servo cylinder 31 at the upper end of the side frame 30 drives the piston rod 3 to push the support frame 32 down, so that the embossing roller 301 is pressed against the surface of the substrate. The electric heating tube 302 is embedded inside the embossing roller 301 and is connected to the inner core of the electric slip ring 305 in the inner cavity 304 of the shaft 2 through the power transmission line 303. The electric slip ring 305 continuously and stably supplies power when the embossing roller 301 rotates, so that the electric heating tube 302 heats up and heats the surface of the embossing roller 301 evenly. The motor 35 drives the shaft 2 34 to rotate in the bearing 2 33. The shaft 2 34 drives the embossing roller 301 to rotate. Under the heating state, the printed substrate surface is rolled to form a clear and durable three-dimensional texture. The support frame 32 can be moved up and down to adjust the embossing depth to ensure consistent texture effect.
