Abstract

The invention discloses a constant-speed descending thickness gauge comprising a control mechanism and a measuring head, wherein the control mechanism comprises a hand wheel, a connecting shaft and a transmission device; the transmission device is fixedly connected with the measuring head and drives the measuring head to move vertically; one end of the connecting shaft is connected with the hand wheel, and the other end of the connecting shaft is provided with a damper; and the middle part of the connecting shaft passes through the transmission device and is fixedly connected with the transmission device. The constant-speed descending thickness gauge has a simple structure, realizes the constant-speed descending operation of the measuring head on the thickness gauge in a mechanical way, and does not need to consume electric energy.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a constant-speed descending thickness gauge used for measuring the thickness of sheet materials such as paper, cardboard and corrugated cardboard. Background technique [0002] The paper and board thickness gauge is suitable for sheet materials such as paper, cardboard and corrugated board. It is a measuring instrument that uses the contact method to measure thickness. The measuring instrument conforms to the standard QB / T1055-2004, and the standard ISO534-1998 is adopted for non-equivalent. [0003] In the standard QB / T1055-2004, there are two kinds of thickness measuring instruments, one is manual control and the other is electric control. However, it is required that the descending speed of the upper measuring head of the thickness measuring instrument in both methods should be constant. The manual control mode controls the descending speed of the upper measuring head entirely by e...
