Rubber cord cutting quality inspection device and method for tires

Abstract

The invention discloses a detection device for cutting quality of a rubberized fabric for a tire. The detection device comprises a detection vehicle main body, a rubberized fabric unwinding device, a rubberized fabric winding device and a digital display angle measuring instrument; the detection vehicle main body comprises an inspection operation table, a vehicle frame and a universal wheel; the universal wheel is installed below the vehicle frame; the vehicle frame is connected with the inspection operation table into a whole; the inspection operation table is provided with a width measuring line b2, a width measuring line b1 and a width measuring line b3; the digital display angle measuring instrument is placed on the inspection operation table; the rubberized fabric unwinding device is arranged at one end of the detection vehicle main body, and the rubberized fabric winding device is arranged at the other end of the detection vehicle main body; and a detection method for cutting quality of the rubberized fabric for the tire comprises the steps of unwinding a fabric roll, starting a motor, measuring a cutting angle, cutting width and big head and small tail, checking the surface quality of the rubberized fabric, determining whether the surface quality is qualified, and winding the fabric roll. The detection device and the detection method disclosed by the invention have the characteristics of easiness in operation, high practicability and the like.

Description

technical field [0001] The invention relates to the detection of rubber cord cutting, in particular to a rubber cord cutting quality detection device and method for tires, belonging to the field of tire manufacturing and processing. Background technique [0002] The tire carcass is the skeleton layer of the tire, which bears 50-80% of the tire's strength, and the tire carcass is made of rubber cord after cutting. Rubber cord cutting is the process of punching and cutting the rubber cord into a semi-finished product with a certain shape, a certain angle, and a certain width through the cutting machine. The quality of cutting is very important to the quality of tires. The key points of cutting quality inspection include the cutting angle, cutting width, cutting head and tail, surface quality, etc. of the cut rubber cord. [0003] The cutting angle refers to the angle between the cutting line and the vertical line in the direction of the rubber cord warp, that is, the complem...

AI Technical Summary

Problems solved by technology

If the unqualified rubber cord with large head and small tail is applied to the tire carcass, the stress distribution will be uneven, and the bearing strength of the carcass will decrease, resulting in partial hollowing out of the carcass or early damage

[0006] The quality measurement of tire cutting angle, width and big end and small tail is very important. Now many companies have set up special cutting quality inspection personnel to carry out quality sampling inspection and on-site quality control of the cut rubber cord, but the inspection of cutting width, cutting angle and big end and small tail are all in Carry out on the conveyor belt of the cutting machine. If the cutting machine is not shut down, the cut cord will be checked on the moving conveyor belt. The inspection data will definitely be inaccurate. If the cutting machine is shut down to ensure the random inspection rate, the cutting efficiency will be affected.

[0007] The existing detection platform for cutting rubber cord mostly adopts a fixed method, which is limited to the detection of this section and cannot be transferred to other required sections, resulting in idle equipment
