Description

Technical Field

[0001] This utility model relates to the field of packaging and printing, and in particular to a printing composite coating equipment. Background Technology

[0002] Printing laminating equipment is a type of machinery used in the printing process to uniformly coat the surface of substrates such as paper, film, and metal foil with coating liquids (such as paints, inks, varnishes, and adhesives) to achieve specific functions (such as decoration, protection, and performance enhancement). It is widely used in packaging printing, book and magazine printing, label printing, and specialty printing.

[0003] In the pharmaceutical packaging and printing industry, slot coating equipment is widely used because it can achieve uniform coating. For slot coating equipment with a long, narrow coating tank, the coating needs to be thoroughly stirred to avoid layering. In existing technology, the common practice is to use multiple stirring mechanisms to stir the coating in the tank.

[0004] However, this approach of using multiple mixing mechanisms has several drawbacks. Firstly, the multiple mixing mechanisms complicate the equipment structure, increasing manufacturing difficulty and production costs. Secondly, each mixing mechanism requires an independent drive source, which not only significantly increases energy consumption and operating costs, but also, if the mixing density is insufficient, some coatings inside the tank may still fail to be effectively mixed. Furthermore, the complex structure makes equipment maintenance and upkeep more difficult, requiring more manpower and resources.

[0005] Therefore, it is necessary to provide a printing and coating equipment to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a printing and coating equipment that solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a printing composite coating equipment comprising: a frame, a coating component, a power take-off component, a substrate, and a printing component. The coating component is disposed on the top of the frame and is used for storing coating and coating. The power take-off component is disposed on the roller assembly. The substrate is located inside the frame. The printing component is installed between the frames and is used for printing on the coated substrate. The equipment also includes: a moving block, a stirring column, a guide rod, a lead screw, a spur gear, and a gear. The moving block is threadedly connected to the lead screw, one end of which is fixedly connected to the power take-off component. The lead screw has a reciprocating thread groove on its surface to drive the moving block to reciprocate on the lead screw. The moving block is slidably connected to the surface of the guide rod to maintain the angle of the moving block during sliding. The stirring column is rotatably connected to the bottom of the moving block for stirring the coating. The gear is fixedly connected to the top of the side surface of the stirring column and meshes with the spur gear.

[0008] Preferably, the coating assembly includes: a silo body, a silo cover, a slot coating device, and a material inlet. The silo body is fixedly connected to the top of the frame and is used to store coating. The silo cover is located on the top of the silo body. The slot coating device is fixedly connected to the bottom of the silo body. The material inlet is located on the top of the silo cover. The guide rod and the spur gear are both fixedly connected to the inner wall of the silo body. The lead screw is rotatably connected to the silo body.

[0009] Preferably, the frame is equipped with a roller assembly, which includes a drive motor, a coating roller, and a coating pressure roller. The coating roller is fixedly connected to the drive end of the drive motor and rotatably connected to the frame. The drive motor is mounted on the frame, and the coating pressure roller is rotatably connected to the frame. It is used to press down on the substrate to apply pressure. The drive motor drives the coating roller to rotate, conveying the substrate and allowing it to pass under the slit coating equipment. The coating pressure roller applies pressure to the substrate to ensure that the substrate is flat and maintains tension, which facilitates uniform coating.

[0010] Preferably, the power take-off assembly includes: a transmission pulley, a belt, and a power take-off pulley. The transmission pulley is connected to the power take-off pulley via the belt. The transmission pulley is fixedly connected to the lead screw. The power take-off pulley is fixedly connected to the coating roller. The power take-off pulley is coaxially fixed with the coating roller and rotates with the coating roller. The power take-off pulley drives the transmission pulley via the belt, thereby driving the lead screw to rotate.

[0011] Preferably, the printing assembly includes: an ink fountain, a gravure roller, and an impression roller. The ink fountain is fixedly connected between the frames, the gravure roller is rotatably connected to the frame and located directly above the ink fountain, and the impression roller is rotatably connected to the frame and rotates in the opposite direction to the gravure roller.

[0012] Preferably, a drying chamber is installed on the frame for drying the liquid coating after the substrate has been coated, and the substrate passes through the drying chamber.

[0013] Compared with related technologies, the printing composite coating equipment provided by this utility model has the following beneficial effects:

[0014] The stirring column simultaneously achieves a combined rotational and horizontal movement within the chamber. The rotational motion, through the impellers or protrusions on the surface of the stirring column, agitates the coating, while the horizontal movement drives the coating to circulate axially within the elongated chamber. This synergistic effect of rotation and translation ensures that the coating at any position within the chamber can be mixed, effectively solving the stratification problem that easily occurs in elongated chambers. It is particularly suitable for the rapid homogenization of high-viscosity, multi-component coatings. Furthermore, using a single drive source to simultaneously control the rotation and horizontal movement of the stirring column eliminates the need for independent power systems for multiple stirring mechanisms, directly reducing equipment manufacturing costs.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 4A printing and coating equipment includes: a frame 1, roller sets 2, a coating component 3, a power take-off component 5, a substrate 6, a printing component 7, and a drying chamber 8. The roller sets 2 are arranged between the frames 1 for conveying the substrate 6. The coating component 3 is arranged on the top of the frame 1 for storing coating and applying it. The power take-off component 5 is arranged on the roller sets 2 for transmitting the power output from the roller sets 2. The substrate 6 is located inside the frame 1 and is conveyed, coated, dried, and printed by the roller sets 2, coating component 3, drying chamber 8, and printing component 7. The printing component 7 is installed between the frames 1 for printing on the coated substrate 6. The drying chamber 8 is installed on the top of the frame 1 for drying the coating, which is still in a liquid state after coating. The equipment also includes: a movable stirring component 4, which is located inside the coating component 3 and connected to the power take-off component 5 for stirring the coating stored in the coating component 3.

[0022] refer to Figure 1 , Figure 3 The movable stirring assembly 4 includes: a movable block 401, a stirring column 402, a guide rod 403, a lead screw 404, a spur gear 405, and a gear 406. The movable block 401 is threadedly connected to the lead screw 404. One end of the lead screw 404 is fixedly connected to the power take-off assembly 5, which drives the lead screw 404 to rotate. The surface of the lead screw 404 has reciprocating thread grooves to drive the movable block 401 to reciprocate on the lead screw 404. The movable block 401 is slidably connected to the surface of the guide rod 403 to maintain the moving block 401. The moving block 401 slides at an angle. Under the pressure of the reciprocating threaded groove and the angle limitation of the guide rod 403, the moving block 401 reciprocates along the surface of the lead screw 404, so that the stirring column 402 can move horizontally and move back and forth in the paint. The stirring column 402 is rotatably connected to the bottom of the moving block 401 for stirring the paint. The gear 406 is fixedly connected to the top of the side surface of the stirring column 402. The gear 406 meshes with the spur gear 405 so that the stirring column 402 will also rotate when it moves horizontally.

[0023] refer to Figures 1-3 The coating component 3 includes: a hopper 301, a hopper cover 302, a slot coating device 303, and a feed inlet 304. The hopper 301 is fixedly connected to the top of the frame 1 and is used to store the coating. The hopper cover 302 is located on the top of the hopper 301 to prevent impurities from entering the coating. The slot coating device 303 is fixedly connected to the bottom of the hopper 301 to facilitate coating the substrate 6. The feed inlet 304 is located on the top of the hopper cover 302 to facilitate the addition of coating. The guide rod 403 and the straight tooth rod 405 are both fixedly connected to the inner wall of the hopper 301. The lead screw 404 is rotatably connected to the hopper 301 so that the stirring column 402 can stir the coating inside the hopper 301. The coating is added to the hopper 301 through the feed inlet 304. After being stirred evenly, it is extruded from the slot coating device 303 at the bottom of the hopper.

[0024] The coating material in the container 301 enters the internal cavity of the slot coating equipment 303 through the pump body. The mold is equipped with a flow channel and a slot outlet. The slot outlet is a narrow slit with a width of tens to hundreds of micrometers. When the coating material passes through this point, it is squeezed into a thin film and adheres to the surface of the moving substrate 6.

[0025] The roller assembly 2 includes a drive motor 201, a coating roller 202, and a coating pressure roller 203. The coating roller 202 is fixedly connected to the drive end of the drive motor 201 and rotatably connected to the frame 1. The drive motor 201 is mounted on the frame 1. The coating pressure roller 203 is rotatably connected to the frame 1 and is used to press down on the substrate 6 to apply pressure, ensuring that the substrate 6 maintains tension during conveying. The substrate 6 moves at a constant speed through the drive of the roller assembly 2, so that the slot coating equipment 303 can coat the substrate 6.

[0026] The power take-off assembly 5 includes: a transmission pulley 501, a belt 502, and a power take-off pulley 503. The transmission pulley 501 is connected to the power take-off pulley 503 via the belt 502. When the power take-off pulley 503 rotates, the belt 502 causes the transmission pulley 501 to rotate synchronously. The transmission pulley 501 is fixedly connected to the lead screw 404, and the power take-off pulley 503 is fixedly connected to the coating roller 202, so as to transmit the power of the coating roller 202 to the lead screw 404 to make it rotate.

[0027] The drying chamber 8 is set on the frame 1 and is used to dry the liquid coating after the substrate 6 is coated. The substrate 6 will pass through the drying chamber 8. The drying chamber 8 is equipped with electric heating tubes and fans. The coated substrate 6 needs to be dried and cured by the hot air generated by the drying chamber to form the final solid coating.

[0028] Substrate 6 enters the device from the inlet end on the left side of the frame 1, passes under the coating roller 203 to maintain tension, passes over the coating roller 202 to be coated, and then enters the drying oven 8 to dry the coating. It then enters the gravure roller 702 and the printing roller 703 for printing. The substrate 6, which has completed coating, drying and printing, is output from the right side of the device and enters the subsequent winding or slitting process.

[0029] refer to Figure 4The printing assembly 7 includes an ink fountain 701, a gravure roller 702, and an impression roller 703. The ink fountain 701 is fixedly connected to the frame 1 and stores solvent-based ink. The ink dries quickly through solvent evaporation. The gravure roller 702 is rotatably connected to the frame 1 and is located directly above the ink fountain 701 so that the ink can be transferred to the substrate 6 when the gravure roller 702 rotates. The impression roller 703 is rotatably connected to the frame 1 and rotates in the opposite direction to the gravure roller 702 so that the impression roller 703 can apply pressure, allowing the ink in the cells of the gravure roller 702 to be better transferred to the surface of the substrate 6, ensuring the clarity and integrity of the printed pattern and text. Both the gravure roller 702 and the impression roller 703 are driven by a printing motor to rotate.

[0030] The working principle of the printing composite coating equipment provided by this utility model is as follows:

[0031] The drive motor 201 drives the coating roller 202 to rotate, and the power is transmitted to the lead screw 404 through the power take-off component 5. The reciprocating thread groove on the surface of the lead screw 404 forces the moving block 401 to make reciprocating linear motion along the guide rod 403 (the guide rod 403 restricts the direction and angle of movement), so that the stirring column 402 moves horizontally back and forth in the bin 301. The gear 406 at the top of the stirring column 402 meshes with the spur gear 405 fixed on the inner wall of the bin 301. When moving horizontally, the gear 406 rolls along the spur gear 405, which drives the stirring column 402 to rotate. The stirring column 402, through the coordinated motion of rotation and translation, stirs the coating in the bin 301 in all directions to avoid stratification.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
