Abstract

The utility model relates to a thin-film electric weak point testing instrument capable of eliminating static electricity, which comprises a rack and a wind-up roller installed on the rack through a rotating shaft, wherein one side below the wind-up roller is provided with a static electricity eliminating device, the static electricity eliminating device comprises a conductive rubber plate, an upper clamping plate and a lower clamping plate, the upper clamping plate and the lower clamping plate are fixed on the conductive rubber plate, the lower end of the conductive rubber plate is fixed between the upper lamping plate and the lower clamping plate, the lower clamping plate is a metal plate, both ends of the lower clamping plate are rotatably fixed on the rack through rotating shafts, and the position enables the upper end of the conductive rubber plate to be obliquely leaned against a wound film roll of the wind-up roller. A thin film can eliminate the static electricity while winding on the wind-up roller, thereby being capable of ensuring the safety of operators.

Description

Can eliminate the thin-film electro weak point test instrument of static

Technical field

The utility model relates to the electric weak point test instrument of plastic sheeting electric property for a kind of detecting electric, specifically a kind of thin-film electro weak point test instrument of eliminating static.

Background technology

Existingly electricly with plastic sheeting electricity weak point test instrument, generally comprise sample roller, guide roller, top electrode, bottom electrode, wind-up roll, and control section forms.CN201017020Y is disclosed is exactly a kind of so electric with plastic sheeting electricity weak point test instrument.This test need to apply high voltage direct current on film.When sample roller film is all wound on wind-up roll, form after film volume, need to manually unload the wind-up roll of coiled film, and again change wind-up roll.During due to replacing wind-up roll, on the film of coiling, with static, operating personnel often suffer damage by static electricity.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, and a kind of thin-film electro weak point test instrument of eliminating static is provided, and can eliminate the static that is wound on the film on wind-up roll, improves the artificial security of changing wind-up roll operation.

For foregoing invention object, the technical solution adopted in the utility model is: it comprises frame, and by the rack-mounted wind-up roll of rotating shaft, below wind-up roll, a side is provided with elimination electrostatic equipment, described elimination electrostatic equipment comprises conductive rubber slab and fixedly conductive rubber slab upper, lower plate, conductive rubber slab lower end is fixed on, between lower plate, lower plate is sheet metal, lower plate two ends are provided with metal rotation axis and are rotatably mounted in frame by rotation axis, its position makes conductive rubber slab upper end can lean against obliquely wind-up roll on the film volume of rolling part.Film contacts with conductive rubber slab when reeling on wind-up roll, and its electric charge passes to frame through conductive rubber slab, metal lower plate and rotation axis, by the ground wire in frame, takes away.

Further, the width of conductive rubber slab is at least 4/5ths of thin-film width.This structural conductive rubber slab and film contact area are large, are easy to take away electric charge.

Further, train wheel bridge is sheet metal.Upper and lower clamping plate are all conductive metal sheet, when being connected with bolt, being convenient to electric charge and flowing to lower plate.

Preferably, lower plate is the balancing weight of thickness thickening, has the screw being connected with train wheel bridge on lower plate.Because lower plate weight is heavier, make conductive rubber slab be pressed on film volume surface, so that electric charge flows on conductive rubber slab, make to eliminate static more thorough.

The beneficial effects of the utility model are: film in volume, can be eliminated in time static on wind-up roll, can guarantee operator safety.And conductive rubber slab can be adjacent on film volume surface by deadweight, eliminates electrostatic equipment structure very simple.

Accompanying drawing explanation

Fig. 2 is the right view of eliminating electrostatic equipment in Fig. 1.

Embodiment

Guide roller, wind-up roll that the electric sample roller with plastic sheeting electricity weak point test instrument of the utility model and being used for is reeled, and be used for the modular constructions such as electrode roller, conduction conductive rubber slab of test can be referring to patent documentation CN201017020Y.

As depicted in figs. 1 and 2, wind-up roll 2 is arranged in frame 1 by rotating shaft 3.

Eliminate electrostatic equipment and be arranged on wind-up roll 2 below rolling part one sides, eliminate electrostatic equipment and comprise conductive rubber slab 4 and the fixing upper and

lower clamping plate

43,42 of conductive rubber slab, train wheel bridge 43 is copper coin, the balancing weight of the thickness thickening that lower plate 42 is made by metallic iron, has the screw being connected with train wheel bridge 43 on lower plate 42.Conductive rubber slab 4 lower ends are fixed between upper and

lower clamping plate

43,42 by bolt 44.Lower plate 42 is fixed by welding on metal rotation axis 41, and rotation axis 41 two ends are rotatably mounted in frame 1, and its position makes conductive rubber slab 4 upper ends can lean against obliquely wind-up roll 2 on the film volume 3 of rolling part.

The width of conductive rubber slab 4 is at least 4/5ths of film 31 width.

In Fig. 2, arrow 5 represents the sense of rotation of wind-up roll 2, and film 31 is by being wound on wind-up roll 2 under wind-up roll 2 one side direction, and conductive rubber slab 4 upper ends lean against on the film volume 3 of the part of rolling obliquely.Static charge on film is through conductive rubber slab 4 and upper and

lower clamping plate

43,42, and rotation axis 41 is passed to frame 1, then derived by the ground wire being electrically connected to frame.
