Description

Horizontal automatic rewinding machine Technical Field The utility model relates to the technical field of rewinding machines, in particular to a horizontal automatic rewinding machine. Background For copper and copper alloy processing industry, slitting packaging is an indispensable process, products are often required to be packaged into various specifications according to customer needs, free conversion from large rolls to small rolls can be achieved through rewinding, although the existing slitting machine can achieve production of products with various specifications through replacing rear-end winding drums, the more the product specifications are, the more winding drums are needed, the more the winding drums are, the more tens of thousands of winding drums are added, and the cost is not small for enterprises, so that a rewinding machine is required to solve the problems. The existing rewinding machine cannot effectively position the placed coiled material, is easy to cause the condition of slipping when the coiled material is rewound, is unfavorable for use of people, is inconvenient to assemble and disassemble, and needs to consume a large amount of time, so that the unreeling efficiency is reduced. Disclosure of utility model The utility model aims to provide a horizontal automatic rewinding machine, which aims to solve the problems of insufficient practicability and inconvenience in assembly and disassembly in the background technology. The horizontal automatic rewinding machine comprises a frame and two turntables arranged on two opposite sides of the top end of the frame, wherein positioning components are arranged on the two turntables, each positioning component comprises a rotating shaft, three fixing rods, a disc, a first bevel gear, a stepping motor, a driving shaft and a second bevel gear, the rotating shafts are rotatably arranged at the center of the upper surface of the turntables, cavities are formed in the inner sides of the turntables, three sliding grooves are formed in the upper surfaces of the sliding grooves, sliding blocks are slidably arranged in the sliding grooves, three arc-shaped sliding grooves which are uniformly distributed in the circumference are formed in the upper ends of the discs in a penetrating mode, the outer surfaces of the three fixing rods are in sliding fit with the inner walls of the arc-shaped sliding grooves, the bottom ends of the three fixing rods are fixedly connected to the upper ends of the sliding blocks, the lower ends of the rotating shafts penetrate through the turntables and extend to the inner sides of the cavities, the first bevel gears are fixedly arranged at the lower ends of the rotating shafts, the stepping motor is fixedly arranged on the side walls of the turntables, the driving shafts are rotatably arranged on the inner sides of the rotating shafts and are in transmission connection with the stepping motor, and the second bevel gears are fixedly arranged on the side walls of the first bevel gears and are meshed with the first bevel gears. Further, the positioning shaft is arranged at the top end of the frame, three groups of positioning shafts are arranged, and the three groups of positioning shafts are positioned in the middle of the front side of the frame and distributed in a triangular shape. Further, a sleeve is sleeved on the positioning shaft positioned on the right side, and a limiting plate is arranged on the sleeve.
