Wrapping machine motor braking device

Abstract

The invention discloses a wrapping machine motor braking device. A horizontal synchronous belt wheel I (4) is connected on the output shaft of a motor (5). A synchronous belt wheel II (2) is arranged at the side surface of the synchronous belt wheel I (4). The synchronous belt wheel II (2) sleeves a wrapping main shaft (1). The synchronous belt wheel I (4) and the synchronous belt wheel II (2) are connected in a transmission way through a synchronous belt (3). A braking disc (6) is arranged on the upper part of the synchronous belt wheel I (4). A braking cylinder is installed at one side of the braking disc (6). An air pipe (9) is connected on the braking cylinder (7). One end of the air pipe (9) is connected with the braking cylinder (7), and the other end of the air pipe (9) is provided with an electromagnetic valve (10). A PLC (11) is connected on the electromagnetic valve (10).

Description

technical field [0001] The invention relates to a motor braking device for an outer winding machine. Background technique [0002] The outer winding machine is an important equipment in the steel cord production equipment, which is used to wind a thinner monofilament on the surface of the cord, so that the cord is easier to attach glue. When the outer winding machine is in normal production, the spindle speed is above 10000r / min. The function of the outer winding head on the main shaft is to evenly wind the 0.15mm outer winding wire on the strand produced in the previous process. The stress is greater than the friction force on the tension friction plate. In the production process, the outer winding head often turns around after parking, which leads to the loose twisting of the outer winding wire, and even accumulation in serious cases, which directly affects the product quality of the cord; in addition , some employees are not standardized during operation, they will light...

Problems solved by technology

When the outer winding machine is in normal production, the spindle speed is above 10000r / min. The function of the outer winding head on the main shaft is to evenly wind the 0.15mm outer winding wire on the strand produced in the previous process. The stress is greater than the friction force on the tension friction plate. In the production process, the outer winding head often turns around after parking, which leads to the loose twisting of the outer winding wire, and even accumulation in serious cases, which directly affects the product quality of the cord; in addition , some employees are not standardized during operation, they will lightly touch the flywheel of the outer winding head with their hands before the inertia of the main shaft stops, so that the main shaft stops and prevents the outer winding head from turning, so there are potential safety hazards during the operation; Floating will report for repairs, and the technicians can only repair by adjusting the tension of the outer winding head, which will not achieve good results and affect the production efficiency of the machine tool
