Description
Technical Field
[0001] This utility model relates to the field of special printing technology, specifically to a glue coating device used in a special printing machine. Background Technology
[0002] Specialty printing is a printing method that uses different plate-making, printing, post-printing processing methods and materials than general printing, and is intended for special purposes. This clearly indicates that the main differences between specialty printing and general printing lie in five aspects: plate-making, printing, post-printing processing methods, material production, and application. Any printing that differs from general printing in any of these five aspects should be classified as specialty printing. Specialty printing possesses features not found in general printed materials, injecting elements that influence the five senses into the printed material, enhancing its expressive effect and better fulfilling its unexpected functions as a printed product. In the process of conveying the printing adhesive liquid, the adhesive storage container works in conjunction with a delivery pump (such as a peristaltic pump or gear pump), adjusting the flow rate according to the required amount of adhesive, and then delivering the adhesive liquid to the coating head through pipelines.
[0003] Existing glue applicators require frequent shutdowns to check their feeding status after a period of use, and timely disassembly, maintenance, and replacement are necessary. This inspection method severely reduces the working efficiency of the printing press. To address this, we designed a special glue applicator for printing presses, improving the glue applicator head to increase the efficiency of head replacement, thereby increasing the overall efficiency of the printing press. Utility Model Content
[0004] The purpose of this invention is to provide a gluing device for use in special printing machines to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating device for a special printing machine, comprising a conveying pipe for conveying coating material, a stabilizing plate fixedly connected to the discharge end of the conveying pipe, sliders fixedly connected to both the front and back sides of the conveying pipe, and protective covers slidably connected to the sliders, small and large clamping plates snapped onto the protective covers, a plug rod fixedly connected to the lower surface of the small clamping plate, a coating head snapped onto the lower surface of the protective cover, a groove formed on the coating head, a return spring fixedly connected to the inner bottom wall of the groove, a convex plate fixedly connected to the top of the return spring, a limiting ring fixedly connected to the side of the coating head, and a support plate provided on the side of the limiting ring.
[0006] Based on the above technical solution, the present invention can be further improved as follows.
[0007] Preferably, the inner wall of the protective cover is provided with a groove to facilitate the lateral movement of the slider, and the lower part of the protective cover is provided with a groove that matches the glue applicator. By setting sliders on the front and back of the protective cover, it is convenient to limit the movement of the pipe by the sliders, and at the same time, it increases the connection between the conveying pipe and the protective cover.
[0008] Preferably, the small card plate is spliced with the large card plate, and the opposite surfaces of the small card plate and the large card plate are provided with semi-circular holes adapted to the conveying pipe. The lower surfaces of the small card plate and the large card plate are provided with multiple plug-in rods, and the upper surface of the protective cover is provided with plug-in holes adapted to the plug-in rods. By setting the small and large card plates, it is convenient to limit the conveying pipe. When the conveying pipe is moved, the position of the small and large card plates can be adjusted to limit the conveying pipe again.
[0009] Preferably, two glue-applying heads are snapped onto the underside of the protective cover, and four protrusions are evenly spaced around the circumference of each glue-applying head. By providing two glue-applying heads, it is convenient to quickly replace the glue-applying heads, increasing the efficiency of maintenance and repair of the glue-applying heads and improving the efficiency of the glue-applying head coating.
[0010] Preferably, both of the glue applicator heads are provided with limiting rings on their sides, and the surface of the limiting rings and the surface of the glue applicator heads are on the same horizontal plane. By providing the glue applicator heads and limiting rings, it is easy to make the top of the glue applicator head be locked inside the protective cover by the limiting rings.
[0011] Preferably, the support plate is located between the two limiting rings and is on the same horizontal plane as the limiting rings. Both sides of the support plate are provided with arc-shaped grooves that are adapted to the sides of the limiting rings. By setting the support plate, it is easy for the conveying pipeline to smoothly transition the stabilizing plate to another glue applicator, thereby increasing the stability of changing the glue applicator.
[0012] Preferably, the support plate is fixedly connected to the inner bottom wall of the protective cover, and the inner bottom wall of the protective cover is provided with a limiting groove that matches the limiting ring. A magnetic block is embedded on the surface of the limiting groove. By setting the limiting ring, it is easy to make the limiting ring snapped and fixed to the protective cover. At the same time, the protective cover is fixed by secondary magnetic attraction of the limiting ring through the magnetic block.
[0013] Preferably, the surface of the stabilizing plate has a liquid passage hole with the same inner diameter as the conveying pipe in the middle. The stabilizing plate is in contact with the surface of the coating head, and the lower surface of the stabilizing plate has a semi-circular groove that matches the top of the convex plate. By setting the stabilizing plate, it is convenient for the conveying pipe to enter the coating head through the liquid passage hole on the surface of the stabilizing plate and flow out. At the same time, the movable convex plate has a certain auxiliary positioning and docking effect for the connection between the conveying pipe and the coating head.
[0014] Beneficial effects
[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0016] This invention, through its conveying pipe, stabilizing plate, and coating head, facilitates the flow of coating material from the coating head. The inclusion of small and large clamping plates provides protection above the protective cover and limits the movement of the conveying pipe. Two coating heads located below the protective cover allow for quick replacement of the coating heads at the ends of the conveying pipe. Furthermore, a limiting ring at the top of the coating head allows it to engage with the protective cover, thus enabling the coating head of this special printing machine to be easily replaceable.
