Abstract

The utility model relates to a touch switch device for packing machine, comprising a micro switch and a press sheet, wherein, the press sheet is a spring sheet, one end of the press sheet is fixed on a switch base, and the other end is arranged on the slide way of the packing belt; the micro switch is fixedly arranged on the base and is positioned on one side of the press sheet. The micro switch can be arranged on the other side opposite to the slide way of the packing belt. The spring sheet of the utility model can be fixed on the base only by two screw nails. The structure is extremely simple. The spring sheet is reset according to the elasticity of the spring sheet. The phenomenon that a shaft is clamped and thus the resetting of the micro switch is influenced can not be produced.

Description

The banding machine trigger switch device

The utility model belongs to and is exclusively used in the banding machine trigger switch device of tightening packing tape.

The operation sequence of banding machine as shown in Figure 1, 2, after tape-feed 10 is sent packing tape 11, through the operator with its pile warp working substance 12, again it is imported lower right side slotted eye slideway, its top is pressed by sheet 13, touch sensitive switches 1 through press sheet 13,, and then drive to push up and cut portion 15 and weld part 16 and tighten and weld, cut off operation with what finish packing tape with control transmission mechanism 14.

At present the sensitive switch mechanism that uses its by sheet 13 be one with nut 132 be axle freely link compressing tablet, its action is subjected to about the resilient contact of packing tape 11 and sensitive switch 1.The shortcoming that exists is the articulated structure complexity, and the axis phenomenon easily takes place, and the faint elastic force of sensitive switch 1 contact can not make pressing tablet 13 reset, so that the machine operation troubles takes place.

The purpose of this utility model is the technical scheme that proposes a kind of novel banding machine trigger switch device, makes that it is simple in structure, operation is reliable, does not produce the axis phenomenon.

Banding machine trigger switch device of the present utility model comprises sensitive switch and by sheet, is a spring leaf by sheet, by sheet one end be fixed on the base, another free end places on the packing tape slideway, sensitive switch is installed on the base, is positioned at by sheet one side.Sensitive switch can be located at the opposite side relative with packing tape.

Embodiment of the present utility model is as shown in drawings:

The end view of Fig. 1, traditional banding machine

Fig. 2, traditional banding machine trigger switch device constructing stereo axis side view

Fig. 3, the design's banding machine trigger switch device structure decomposition view

Fig. 4, the design's banding machine trigger switch device constructing stereo assembled view

One of Fig. 5, the design's banding machine trigger switch device action schematic diagram

Two of Fig. 6, the design's banding machine trigger switch device action schematic diagram

Number in the figure is represented respectively:

1, sensitive switch, 2, base, 21, slotted eye, 22, screw, 3, spring leaf, 31, the free contravention of spring leaf, 32, the spring leaf stiff end, 4, screw, 5, pad.

In conjunction with the accompanying drawings the utility model is specified:

Consult shown in Fig. 3,4: base 2 is provided with screw 22, and available screw 4 locks a sensitive switch 1, a metal spring sheet 3 respectively on it.An oval slotted eye 21 is established in the appropriate location of base 2, but ammunition feed reed 3 front ends 31 therefrom wear service position to base.The rear end 32 of spring leaf 3 is stiff ends, is fixed on the base 2 with screw 4.Pad 5 can increase coupling mechanism force.

Spring leaf 3 of the present utility model only needs two screws 4 just can be installed on the base 2, and structure is extremely simple.Rely on the elastic reset of spring leaf self, also can not produce the axis phenomenon.

Method of operation of the present utility model is shown in Fig. 5,6, and when packing tape 11 touched the top 31 of spring leafs 3, the side of spring leaf 3 was pushed sensitive switch 1 and made tightening, welding of packing tape and cut off action and be accomplished.When taking parcel away, spring leaf 3 is according to self elastic reset, and switch 1 also automatically resets.Can not produce the axis phenomenon.

Claims

1, a kind of banding machine trigger switch device, comprise sensitive switch and by sheet, it is characterized in that by sheet be a spring leaf, by sheet one end be fixed on the switch pedestal, the other end places on the packing tape slideway, sensitive switch is fixedly installed on the base, is positioned at by sheet one side.

2, trigger switch device as claimed in claim 1, its feature is arranged on the relative side in addition of packing tape slideway in sensitive switch.
