Description

Technical Field

[0001] This utility model relates to the technical field of roller press equipment, specifically a roller angle adjustment device for a roller press. Background Technology

[0002] In the luggage manufacturing industry, the case shell is typically manufactured by heating and roll forming thermoplastic sheets. Existing roll forming machines usually consist of multiple sets of rollers at fixed angles, through which the sheet material is passed in sequence and gradually bent into the desired arc shape; In response, Chinese utility model patent CN220940980U discloses a roller press with an easily adjustable initial gap, relating to the field of roller press technology, and solving the technical problem of inconvenient adjustment. The invention includes a base with two mounting plates fixedly installed on its top. A first pressure roller is rotatably mounted on the side of the base near the mounting plates, and a second pressure roller is rotatably mounted between the two mounting plates. An adjustment assembly is provided on the base, including an adjustment plate. A reciprocating groove is formed on the side of the base near the first pressure roller, and a bidirectional screw is rotatably mounted within the reciprocating groove. Reciprocating blocks are threaded through the bidirectional screw near both ends. The adjustment plate is fixedly mounted on the side of the reciprocating groove away from the base. A first motor is fixedly mounted on one side of the base. Rectangular through holes are formed on the two mounting plates. This design facilitates adjustment and improves the adjustability and flexibility of the device. When adjusting the rollers on a roller press is required, the machine must be stopped and the entire roller assembly manually replaced or adjusted. Manual adjustment relies on the operator's experience, making it difficult to ensure consistent angles each time, and the replacement process is quite cumbersome. Therefore, we propose a roller press roller angle adjustment device to solve the above problems. Utility Model Content

Multiple telescopic grooves 203 are evenly provided on the inner wall of the adjustment port 201 near the fixing screw 6. The bottom surface of the telescopic grooves 203 is provided with through holes 204. Positioning components 7 are provided in the through holes 204. The side wall of the movable frame 4 is provided with a positioning groove 402 corresponding to the telescopic grooves 203. An indicator block 403 is fixed to the outer wall of the movable frame 4 near the fixing screw 6. A label 8 is provided on the outer wall of the mounting plate 2 corresponding to the positioning component 7. Please see Figure 2 and Figure 3 One end of the movable frame 4 is symmetrically fixed to one end of the protective enclosure 9 near the fixed screw 6. The fixed screw 6 is located inside the protective enclosure 9. The other end of the protective enclosure 9 is engaged in the annular engagement groove 205 provided on the inner wall of the adjustment port 201. The inner wall of the annular engagement groove 205 is provided with a limiting groove 206. A limiting block 901 is engaged in the limiting groove 206.
