Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and more specifically, to a high-speed inkjet printing device with a curved surface mode. Background Technology

[0002] Curved surface inkjet printing equipment is a specialized device capable of inkjet printing on curved surfaces. It can be used to print brand logos and decorative patterns on the curved parts of specially shaped packaging products, such as cylindrical cosmetic bottles and irregularly shaped gift boxes, enhancing the packaging's aesthetics and recognizability to attract consumers.

[0003] To achieve accurate printing on curved surfaces, the printhead needs to move precisely in space to match the shape of the surface. Through a high-precision mechanical transmission system and advanced motion control algorithms, the printhead can move along the contour of the surface, ensuring that ink droplets are evenly distributed across different positions. Existing inkjet printing devices, to adapt to the curved surface structure of products, require a high-precision transmission structure to change the spatial position of the printhead and maintain a consistent distance between the printhead and the surface to be printed. However, this sensor-controlled approach suffers from poor synchronization among multiple printheads, easily leading to errors that affect production quality. Therefore, we propose a high-speed inkjet printing device for curved surfaces. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a high-speed inkjet printing device with a curved surface mode to solve the technical problem that the current transmission structure adjusts the spatial position of the printhead, resulting in poor synchronization of multiple printheads and easily affecting production quality.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a high-speed inkjet printing device with curved surface mode, including a retainer, a rotating ring, a plastic sheet, and a frame assembly. Two retainers are provided, and each retainer has a pin end at both ends. The pin ends of the retainers are mounted on the base of an assembly plate. A linkage component is provided inside each pin end, and an adjustment groove is opened at the inner end of each pin end. A screw is rotatably installed in the adjustment groove. The rotating ring is rotatably mounted on the two retainers, and baffles are fixed to the upper ends of both sides of the rotating ring. A drive tooth is provided in the middle of the upper surface of the retainer. Two frame assemblies are provided, and the frame assemblies are mounted on the retainers. Each frame assembly consists of a column and a spring crossbar, and a sliding column is fixed to the lower end of the column. The sliding column is slidably installed in the corresponding adjustment groove, and the plastic sheet is slidably installed between the spring crossbars.

[0006] In use, the workpiece is placed into the inner cavity of the rotating ring, and then adjusted to fit the curvature of the workpiece surface. The motor inside the base is started to drive the drive wheel, which in turn drives the driven wheel to rotate synchronously via belt transmission. The driven wheel drives the screw to rotate through the first meshing tooth engaging the second meshing tooth. The screw thread drives the sliding column to move, and the two columns at both ends of the frame assembly expand outward synchronously, causing the spring steel horizontal column to plastically expand and change its curvature to fit the curved surface of the workpiece. The plastic sheet expands in the same way to fit the curvature through the sliding sleeve. Through the above structural design, the spring horizontal column that drives the nozzle movement changes shape and its movement trajectory is adapted to the workpiece. The machined workpiece has a curved surface, eliminating the need for sensors and mechanical transmission structures to change the spatial position of the nozzle, thus reducing the error rate. The motor that starts the drive teeth drives the rotation, and the drive teeth mesh with the meshing groove to drive the rotating ring to complete the rotation. During the rotation of the ring, the baffle deflects, and the deflection of the baffle pushes the bottom of the lower extension rod, causing the plastic sheet to move. The plastic sheet slides on the spring crossbar through a sliding sleeve, and the plastic sheet drives the nozzle to change the printing position, expanding the spraying area. Through the above structural design, the nozzle is moved during the rotation of the ring, and the distance between the nozzle and the curved surface of the workpiece is always consistent, ensuring the quality of the finished product. The nozzles on both sides are moved relative to each other at the same time, reducing the difficulty of operation.

The inner cavity of the base is rotatably equipped with a drive wheel. The linkage component is composed of a driven wheel and a first meshing tooth, and the drive wheel is connected to the two corresponding driven wheels by belt drive.

[0009] Preferably, one end of the screw is provided with a second meshing tooth, and the second meshing tooth is engaged with the first meshing tooth, and the screw thread passes through the sliding post.
