Description

Technical Field

[0001] This utility model relates to the field of printing press automation technology, and in particular to a connection structure between a printing press encoder and a printing roller. Background Technology

[0002] During the printing process, the encoder is connected to the end of the printing roller to control the automatic dispensing of ink and adhesive, thus achieving automated printing. In existing printing presses, the connection between the encoder and the printing roller is rather crude; some manufacturers even use tape or glue for connection. This often results in the encoder failing to detect the rotation of the printing roller, thus preventing automatic ink and adhesive dispensing. Furthermore, it's worth noting that the encoder is typically fixed to the printing press frame using an L-shaped steel plate. This crude connection leads to poor coaxiality between the encoder and the printing roller, ultimately causing frequent downtime for maintenance.

[0003] To solve the above problems, a connection structure between the encoder and the printing roller of a printing press is provided. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a connection structure between the encoder and the printing roller of a printing press, which effectively solves the problems of poor coaxiality between the printing roller and the encoder and the need for frequent maintenance and repair.

[0005] The technical solution includes a printing roller and an encoder. A connecting component is fastened to the printing roller. The connecting component includes a circular plate with multiple U-shaped plates evenly distributed around its left edge. The openings of the U-shaped plates face right. The multiple U-shaped plates and the circular plate form a buckle, which is fastened to the end of the printing roller. The encoder has a cylinder with its sidewall placed inside the cavity of the U-shaped plate. A steel ring is located on the outside of the buckle, which can tighten and fix the U-shaped plate, the cylinder, and the printing roller.

[0006] Furthermore, the right end of the U-shaped plate on the outer side plate is inclined inward, so that the outer edge of the buckle is a conical surface with a larger diameter at the left end than at the right end.

[0007] Furthermore, the outer wall of the buckle is provided with multiple grooves, and the steel ring is located in the grooves.

[0008] Furthermore, the steel ring is formed by bending a single steel bar, with both ends of the steel bar fixedly connected together by a bolt and nut structure, which controls the diameter of the steel ring.

[0009] This utility model has an ingenious structure that enables the encoder and the printing roller to be securely fixed together while ensuring their coaxiality. It is not only easy to disassemble but also easy to install, making it highly practical. Attached Figure Description

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 4 The present invention includes a printing roller 1 and an encoder 2. A connecting component is fastened to the printing roller 1. The connecting component includes a circular plate 3. Multiple U-shaped plates 4 are evenly distributed around the left edge of the circular plate 3. The openings of the U-shaped plates 4 face to the right. The multiple U-shaped plates 4 and the circular plate 3 form a buckle, which is fastened to the end of the printing roller 1. The encoder 2 has a cylinder 5. The side wall of the cylinder 5 is placed inside the cavity of the U-shaped plate 4. A steel ring 6 is located on the outside of the buckle. The steel ring 6 can tighten and fix the U-shaped plates 4, the cylinder 5 and the printing roller 1.

[0016] In order to achieve a reliable connection between the printing roller 1 and the encoder 2, the right end of the U-shaped plate 4 on the outer side is inclined inward, so that the outer edge of the cap is a conical surface with a larger diameter at the left end than at the right end.

[0017] To prevent the steel ring 6 from falling off, multiple grooves 7 are provided on the outer wall of the buckle, and the steel ring 6 is placed in the grooves 7.

[0018] In order to adjust the size of the steel ring 6, the steel ring 6 is made by bending a steel bar, and the two ends of the steel bar are fixedly connected together by a bolt and nut structure 8, which controls the diameter of the steel ring 6.

[0019] It is worth noting that multiple steel rings 6 can be set, and the bolts on the multiple steel rings 6 are evenly distributed around the printing roller 1 to prevent vibration during rotation.

[0020] When using, such as Figure 2As shown, first, the cap is fastened to the end of the printing roller 1. Then, the ring on the encoder 2 is inserted into the cavity of the U-shaped plate 4. At this time, multiple U-shaped plates 4 clamp the cylinder 5. Subsequently, multiple steel rings 6 are fitted onto the outside of the cap, and the bolts are tightened, causing the steel rings 6 to press the outer plates of the U-shaped plates 4 towards the center, ultimately making the printing roller 1 and the cylinder 5 on the encoder 2 coaxially and securely connected. When disassembly is required, the encoder 2 can be easily and quickly removed by loosening the steel rings 6.

[0021] This utility model has an ingenious structure that enables the encoder 2 and the printing roller 1 to be securely fixed together while ensuring their coaxiality. It is not only easy to disassemble but also easy to install, making it highly practical.
