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
The present invention relates to a kind of surveying instrument, relate in particular to a kind of constant-speed descending thickness gauge of the thickness measurement for flaky materials such as paper, cardboard and corrugated boards.
Background technology
The paper and Board thickness measuring instrument is applicable to the flaky materials such as paper, cardboard and corrugated board.It is a kind of analyzer that adopts the contact method detect thickness.Analyzer meets standard QB/T1055-2004, non-adopting by equivalent standard ISO 534-1998.
In standard QB/T1055-2004, containing has two kinds of thickness measuring instruments, and a kind of is manually to control, and a kind of is electronic control.But require the decline rate of upper measuring head of dual mode thickness measuring instrument all constant.Manual control mode is controlled upper measuring head decline rate fully by experience, can not guarantee each constant airspeed; Electronic control mode is because drag moving up and down of upper measuring head by motor, so speed can be protected, but must consume electric energy, environmental protection not, and increased the manufacturing cost of thicknessmeter, uneconomical.
Summary of the invention
The technical problem to be solved in the present invention is that existing thicknessmeter decline rate is non-constant, perhaps need expend a large amount of electric energy for reaching constant effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of constant-speed descending thickness gauge, comprise control gear and measuring head, and described control gear comprises handwheel, coupling shaft and gearing, gearing and measuring head are connected, and the drive measuring head moves up and down; Coupling shaft one end connects handwheel, and an end is provided with damper, passes gearing and is connected with it in the middle part of coupling shaft.
One aspect of the present invention drives by rotation hand wheel the rising that gearing is realized measuring head; Utilize on the other hand measuring head deadweight to descend, and in addition damping, to realize that the measuring head decline rate is less than 3mm/s; Described damper can use existing flexible member, torsion spring for example, and torsion spring set is on coupling shaft, and its a end is fixed on external shell, and an end and gear are affixed, and the force direction when its force direction moves downward with measuring head is opposite; The present invention realizes measuring head constant-speed descending on thicknessmeter mechanically, has both guaranteed the constant of upper measuring head decline rate, and drags more more economical, environmental protection with respect to motor.
As a modification of the present invention scheme, described gearing comprises pitch wheel, tooth bar, and gear and coupling shaft are connected; Tooth bar vertically arranges, and its lower end is connected with measuring head.
Advantage of the present invention is: simple in structure, and realize mechanically measuring head constant-speed descending on thicknessmeter, and need not consume electric power.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of gearing of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Fig. 1-2, the gearing 4 lower ends measuring head 5 that is connected, and drive measuring head 5 and move up and down; Coupling shaft 2 one ends connect handwheel 1, one end and are provided with damper 3, and its middle part is passed gearing 4 and is connected with it; Described gearing 4 comprises pitch wheel 4-1 and tooth bar 4-2,, gear 4-1 and coupling shaft 2 are connected; Tooth bar 4-2 vertically arranges, and its lower end is connected with measuring head 5; Described damper 3 is torsion spring, and torsion spring set is on coupling shaft, and the two ends of torsion spring connect respectively external shell and gear 4-1, and when the force direction of torsion spring descends with measuring head 5, the sense of rotation of gear 4-1 is opposite.
During work, but shake handwheel 1 driven gear 4-1 rotation, thereby band carry-over bar 4-2 moves upward, the measuring head 5 that is connected to tooth bar 4-2 bottom also makes progress thereupon; Then, detected materials is placed on below measuring head 5, unclamps handwheel 1, under the double reaction plus of measuring head 5 deadweights and damper 3, the slow constant-speed descending of measuring head 5 is until contact with detected materials.
