Description

Technical Field

[0001] This utility model relates to the field of printing processing technology, specifically to a printing surface gloss treatment device. Background Technology

[0002] Gloss treatment of printed materials is a processing technique that adds a layer of glossy material to the surface of printed materials. For example, depending on the characteristics of the advertised goods or inner packaging items, specific varnishing effects can be selected to highlight the inherent characteristics of the goods and give people a refreshing feeling, such as spot varnishing, matte treatment, pearlescent effect, etc.

[0003] As disclosed in authorization announcement number CN213830955U, a device for partial surface gloss treatment of environmentally friendly printed materials includes a conveying platform, a varnishing mechanism, a drying mechanism, and an electrical control cabinet. The varnishing mechanism and the drying mechanism are sequentially installed at the upper end of the conveying platform along the conveying direction. The beneficial effects of this utility model are: by setting up the varnishing mechanism and the drying mechanism, the varnishing mechanism can automatically varnish the passing printed materials, eliminating the need for manual varnishing, saving time and effort while improving work efficiency.

[0004] Although the aforementioned patent eliminates the need for manual varnishing, the device relies on the absorption and compression of an oil-absorbing sponge to complete the varnishing process. Once the sponge is saturated, any additional varnish cannot be effectively absorbed and is prone to dripping from the edges of the template. This not only wastes the varnish but also contaminates the conveyor belt, the printed materials to be processed, and the equipment itself, leading to a decrease in product yield and additional cleaning costs.

The detection end of the liquid level sensor 8 extends into the interior of the transfer box 5. A horizontal support 9 is fixedly connected inside the transfer box 5. A movable hole 10 is provided through the middle of the support 9. The guide rod 11 is slidably connected to the inside of the 10. The bottom end of the guide rod 11 is fixedly connected to the valve core 12. The guide rod 11 is movably sleeved with a spring 13. The two ends of the spring 13 abut against the valve core 12 and the bracket 9, respectively. The top end of the guide tube 6 is provided with a stepped groove 14 that matches the valve core 12. The top center of the coating box 4 is fixedly connected to the connecting pipe 15. The middle of the connecting pipe 15 is provided with a connecting groove 16, and the top ends of both sides are provided with openings that communicate with the connecting groove 16. The lifting frame 3 is raised and lowered on the front of the frame 2 and located below the supply mechanism by a lifting mechanism. The lifting mechanism includes an electric push rod 17 that is vertically fixedly connected to the outside of the right side of the top of the frame 2, and a through-hole is provided in the middle of the frame 2. The sliding groove 18 is fixedly connected to the middle right side of the lifting frame 3, and a slider 19 that slides with the sliding groove 18 is fixedly connected to the slider 19. The output shaft of the electric push rod 17 is fixedly connected to the slider 19. A guide groove 20 is opened through the middle of the top of the frame 2. A rack 21 that slides with the guide groove 20 is fixedly connected to the middle of the top of the lifting frame 3. A gear 22 that meshes with the rack 21 is rotatably connected to the front of the frame 2 via a bearing. A sleeve 23 is fixedly connected to the middle of the front of the gear 22. Dovetail guide rails 24 are fixedly connected to both sides of the bottom of the front of the frame 2. A receiving hopper 25 is provided between the two dovetail guide rails 24. Dovetail guide bars 26 that slide with the dovetail guide rails 24 are fixedly connected to both ends of the receiving hopper 25. The bottom of the back of the receiving hopper 25 is fixedly connected to the dovetail guide rails 24. A discharge pipe 27 is fixedly connected to the top of the back of the receiving hopper 25, and a screw 28 threadedly connected to the sleeve 23 is fixedly connected to the top of the back. The coating box 4 is fixedly connected to the front of the lifting frame 3. A coating mechanism is provided below the coating box 4. The coating mechanism includes a rolling groove 29 that runs through the middle of the bottom end of the coating box 4, and a transfer roller 30 that is rotatably connected to the inside of the rolling groove 29 through a bearing. Sealing strips 31 that contact the circumference of the transfer roller 30 are fixedly connected to both sides of the inner wall of the rolling groove 29. A coating roller 32 is rotatably connected to the bottom end of the coating box 4 through a bearing. The coating roller 32 and the transfer roller 30 roll in contact. Several support seats 33 are evenly distributed on the outer periphery of the belt of the belt conveyor 1. The length of the transfer roller 30 matches the support seat 33. In this embodiment, by setting up a coating box 4 and a transfer box 5, and utilizing the dynamic docking structure of the connecting pipe 15 and the conduit 6, the automatic and quantitative replenishment of varnish is realized, solving the problem of oil dripping caused by adsorption saturation in the traditional sponge oil storage method.

[0014] Furthermore, by adopting a rolling coating mechanism consisting of a transfer roller 30 and a coating roller 32, the traditional sponge pressing method of coating is replaced by roller contact and rotation coating, which solves the problem of uneven coating thickness caused by sponge elastic deformation and uneven oil absorption.

[0015] Working principle: The belt conveyor 1 transports the printed matter fixed by the support 33 in a step-by-step manner. When the printed matter moves directly below the coating roller 32, the conveying stops. The electric push rod 17 drives the lifting frame 3 to descend via the slider 19, so that the coating roller 32 fixed at the bottom of the coating box 4 abuts against the upper surface of the printed matter. Then the belt conveyor 1 restarts. During the horizontal movement of the printed matter, the friction drives the coating roller 32 to rotate. At this time, the varnish in the coating box 4 is transferred to the coating roller 32 via the transfer roller 30 and is finally evenly coated on the surface of the printed matter. When the printed matter is completely removed from the coating roller 32, the electric push rod 17 immediately drives the lifting frame 3 to rise. At this time, the connecting pipe 15 fixed on the lifting frame 3 moves upward and inserts into the guide pipe 6 at the bottom of the transfer box 5. The top of the connecting pipe 15 pushes open the valve core 12 to disengage it from the stepped groove 14. Spring 1 The varnish in the transfer box 5 is compressed and flows into the coating box 4 through the conduit 6 and the connecting groove 16 to complete the automatic replenishment. During this docking process, as the lifting frame 3 rises, the rack 21 fixed at its top moves upward synchronously and drives the gear 22 to rotate, which in turn drives the sleeve 23 fixed to the gear 22 to rotate. The screw 28 threadedly connected to the sleeve 23 then drives the receiving hopper 25 to slide backward along the dovetail guide rail 24 through the dovetail guide bar 26, thereby making room for the space below the transfer box 5. When the coating box 4 is replenished and descends to disengage, the valve core 12 re-seals the stepped groove 14 under the reset action of the spring 13. At the same time, the lifting frame 3 descends and drives the receiving hopper 25 to return to the ground directly below the transfer box 5 through the meshing transmission of the rack 21 and the gear 22. At this time, if there is residual varnish dripping at the conduit 6, it will be picked up by the receiving hopper 25 and collected.

[0016] In the specific implementation of this technical solution, the coordinated control of the belt conveyor 1 and the electric push rod 17 can be configured with conventional PLC controllers, microprocessors, or relay control systems found in existing technologies. Although such control systems are not described in detail in this technical solution, they are control units that can be conventionally selected by those skilled in the art based on actual intermittent conveying and precise positioning requirements. Their signal interaction and program logic follow well-known technologies in this field and do not affect the implementation of the core innovation of this solution. In practical applications, the control system is mainly used to coordinate the start and stop of the conveyor and the lifting sequence of the lifting frame, but its specific type and connection method can be adjusted according to production requirements, all of which fall within the reasonable extension scope of this technical solution.

[0017] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
