Device for using ultrasonic waves to detect wall thickness of rubber tube

Abstract

The invention provides a device for using ultrasonic waves to detect the wall thickness of a rubber tube. The device includes a probe, a pre-amplifier, a band-pass filter and a single-chip microcomputer, a water tank is arranged right under the probe, the front end of the probe is located under a water surface of the water tank, the water tank is internally provided with a rubber tube, the rubber tube is submerged in the water tank, an ultrasonic transmitting device and an ultrasonic receiving device are arranged on the probe, the probe is connected with the pre-amplifier, the pre-amplifier is connected with the band-pass filter, the band-pass filter is connected with the single-chip microcomputer, and a timer is arranged on the single-chip microcomputer. The device for using the ultrasonic waves to detect the wall thickness of the rubber tube provided by the invention has the beneficial effects that by use of the device, a process of on-line detection of the wall thickness of the rubber tube is more convenient, and parameters of an extruder can be adjusted in time by use of data that are obtained, thereby obtaining the rubber tube with qualified wall thickness, and saving raw materials.

Description

technical field [0001] The invention belongs to the field of rubber hose quality detection devices, in particular to a device for detecting the wall thickness of rubber hoses by ultrasonic waves. Background technique [0002] The size of the rubber hose is one of the important indicators for the qualification of the rubber hose. The existing rubber hose size detection device such as the laser caliper is expensive, and generally directly detects the finished product. It cannot be directly detected on the production line and the results are fed back in time to make a Adjustment. The extruder is the equipment in the rubber hose production process. During the extrusion process, the viscosity of the rubber material, the size of the rubber strip, the temperature of the extruder, the number of revolutions, the pressure and other factors will affect the size of the extruded rubber hose. Online testing is extremely important. Ultrasonic ranging is a traditional, easy-to-operate, an...
