Description

Lead sealing pliers

Technical field

The invention belongs to industrial packaging case envelope note field, and in particular to a kind of lead sealing tonger of packing case, suitable for weight Want article encapsulate after lead sealing to packing case.

Background technology

With the development of scientific and technological level, the industrial circle level of informatization increasingly strengthens, but in foreseeable future, Informationization technology means still can not substitute the handwork of the mankind completely, especially need high safety guarantee relate to core, The fields such as involving explosives, the design and manufacture for the staple product such as be involved in drug traffic, processing transport, maintaining, traditional artificial detection, are encapsulated manually Still it is presently the most the Safety Insurance being widely recognized as.The storage of such product, generally there is special packing case, using iron wire and Lead cake carry out seal, by check suppress after the seal of lead cake confirm packing case it is intact, this be current army relate to core, involving explosives, relate to One of the most commonly used envelope note technological means of the important departments such as poison.Lead sealing pliers is the specific purpose tool for suppressing lead cheese into envelope note, is passed For the lead sealing pliers of system without only control measure, compacting dynamics is uncontrollable, the lead cake poor quality of compacting, lead cake crushing chip off-falling, lead easily occurs The quality problems such as cake seal is fuzzy to be not easy to recognize, lead pieshape is strange, influence envelope note quality, meanwhile, traditional lead sealing pliers is also deposited Dehisce the problem of excessive, take care of and using very inconvenient in pressure handle.

The content of the invention

The purpose of the present invention is in view of the above-mentioned problems existing in the prior art, there is provided a kind of new lead sealing pliers, is being improved While lead sealing quality, guarantee envelope note effect, it is also convenient for keeping and uses.

To achieve these goals, the present invention uses following technical scheme：

A kind of lead sealing pliers, including base, base handle, pressure handle, it is upper label module, it is lower label module and only control device.Base is V-shaped, Base handle, pressure handle are rotatablely connected with base respectively, and the fixing end of pressure handle and base is cam structure, and pressure handle is provided with reclinate pressure Handle turns to area, is provided with spring in base, the both ends of spring are connected with base handle, base respectively；Base handle is provided with only control device, including only Boss, positioning screw, Self-locking screw, observation window are controlled, installing screwed hole in the centre bit of only control boss is used to install positioning screw, Positioning screw is locked by Self-locking screw, described screwed hole is provided with band perpendicular to base handle, and in the side of screwed hole The observation window of scale；Upper label module is perpendicularly fixed at the front end of base handle, including upper label mould, upper adjust pad, upper Self-locking screw, on Moulding, upper label mould is the cylinder provided with ring screw, and seal type matrix is carved with bottom, the hold-down support insertion base that top is provided with The slotted eye of handle front end is simultaneously locked by upper label mould fastener, and upper moulding is reducing annulus that big footpath annulus, path annulus form, Its inner ring surface is provided with screw thread, and the anchor ring of big footpath annulus is provided with breach, and upper moulding is set in label mould and by upper Self-locking screw Locking, upper adjust pad are set in label mould and positioned at the tops of upper Self-locking screw；Lower label module matches with upper label module, position In on base, including lower label mould, lower adjust pad, lower Self-locking screw, under moulding, lower label mould is the cylinder provided with ring screw Seal type matrix is carved with body, top, and the slotted eye for the hold-down support insertion base front end that bottom is provided with simultaneously is locked by lower label mould fastener Tightly, moulding is big footpath annulus, the reducing annulus of path annulus composition under, and its inner ring surface is provided with screw thread, the anchor ring of big footpath annulus Provided with breach, under moulding be set in lower label mould and locked by lower Self-locking screw, lower adjust pad is set in lower label mould and position In the bottom of lower Self-locking screw.

Further, base is perpendicular to the upward length L=2H of lower label mold shaft₁+3.6H₀+ (10~30), H₁For lower label Mould height, H₀For lead cake height.

Further, base handle is away from the side length L of base one_p≥k·σ·π·r²L/400, nargin coefficient k=1~3, σ =16Mpa, r are lead cake radius, and L is base perpendicular to the upward length of lower label mold shaft.

Further, upper moulding and under moulding big footpath internal radius R, the height H and lead cake radius of big footpath annulus R, the high h in lead cake hole₀With lead cake height H₀Relation meetWith

Compared with prior art, the present invention has advantages below and beneficial effect：

1st, upper and lower label module has detachable and replaceability, the lead cake of compatible original specification, technology upgrading cost low；

2nd, lead sealing pliers of the present invention has only control device, and the compacting dynamics to lead cake is controllable, is not in lead cake pressure Go to sticks and staves block, the seal of lead cake it is fuzzy be not easy to recognize, the problems such as lead pieshape is strange, can ensure to suppress seal stable operation consistent；

3rd, pressure handle is designed as bending-type, so that lead sealing pliers highly folds in no load state, floor space is small, It is easy to keeping, preservation and packed and transported.
