The structure of the semi-automatic plate rolling machine is a three roll symmetrical type. The upper roller performs vertical lifting motion at a symmetrical position between the two lower rollers, and the lifting of the upper roller is achieved through a screw, which deforms the material being rolled. This rolling machine is a universal equipment used for bending and deforming metal sheet profiles. It uses special tools or other equipment to pre bend the end face of the sheet and can roll circular and curved workpieces. It has a wide range of applications in the petroleum, chemical, boiler, hydropower, shipbuilding, industrial equipment installation, and mechanical manufacturing industries. The machine uses the reversing switch (installed on the coiling machine) to realize the forward and reverse rotation of the coiling plate. After checking that the machine is correct, adjust the lead screw to make the upper roll press to the surface of the plate. Turn the reversing switch to "reverse" and "forward". Depending on the end of the plate placed on the site, let the motor rotate forward or reverse. After coiling one side, manually adjust the lead screw to make the upper roll press the plate and roll it in "reverse" and "forward", so on until the requirements are met.

Mechanical automatic three roll plate rolling machine, used to roll steel plates into cylindrical, curved, and conical shapes.

The upper roller presses down and is driven by an attached motor through a reducer to transmit power to the worm gear, screw and nut pair, causing the plate to bend and deform. The rolling transmission is driven by the main motor through the main reducer and open gear to rotate the lower roller, and becomes the main power source during plate rolling. The upper roller device consists of an upper roller, an upper roller bearing seat, etc. Sliding bearings are installed on the bearing seats at both ends of the upper roller. The upper roller lifting is driven by a worm gear, and the pressing device is powered by an attached motor. The torque is transmitted through the mechanical linkage of the reducer, worm gear, screw nut to move the upper roller up and down. The lower roller device consists of a lower roller, a lower roller bearing seat, a lower roller gear, and sliding bearings. The lower roller is the active roller, and the gear on the output shaft of the main transmission reducer drives the lower roller gear to transmit torque to the lower roller. It is mainly composed of a reverse handle, a flip head body, a movable hinge, etc. The function of the flipping device is to facilitate the removal of the finished product.

The equipment is made of welded steel plates, with high mechanical strength, precision, and practicality. The adjustment and operation of the parallelism between the upper and lower rollers are simple, and the equipment maintenance is convenient.
