Description
Technical field
The present invention relates to a kind of rotating disc type vacuum packing machine, be specifically related to the unit clamp assembly in a kind of rotating disc type vacuum chamber of vacuum packaging machine.
Background technology
At present, a lot of packaging for foodstuff adopts vacuum packaging, and vacuum-packed food can improve the shelf-life greatly, and vacuum packaging has been sealed after being vacuumized in vacuum chamber by non-sealing package bag, at present, market has adopted rotating disc type vacuum packing machine to carry out the vacuum packaging of food.Rotating disc type vacuum packing machine is generally made up of multiple vacuum chambers of a rotating disk and circumference laying on rotating disk, during work, rotating disk calibration rotates and drives all vacuum chamber synchronous axial system, in the indexing process of rotating disk, packaging bag is clamped by unit in vacuum chamber, carries out the heat-sealing of packing bag mouth after evacuation.Due to the film thickness of packaging bag and sack width different, so very thin for some film thickness or that sack width is larger packaging bag, when unit folder is clamped it, unavoidably there is gauffer situation in sack, such sack is after carrying out heat sealing through hot knife, also unavoidably there is gauffer in various degree, affect vacuum packaging quality.
Summary of the invention
In view of the deficiency that background technology exists, object of the present invention is intended to provide in a kind of vacuum chamber being applied to rotating disc type vacuum packing machine, has unit and presss from both sides monolateral tension function, and unit that is simple and reasonable, that improve vacuum packaging quality presss from both sides monolateral strain component.
The present invention implements by following technical solution:
Unit presss from both sides monolateral strain component, comprise inner splint, external splint, pendulum plate and fork, the relative inner splint of external splint makes horizontal hunting, external splint is connected on pendulum plate, pendulum plate is fixedly connected with fork, fork rotates and is located in vacuum chamber, it is characterized in that: inner splint is by fixing inner splint and floating inner splint forms, fixing inner splint is fixedly located on interior holder, the inner splint that floats floats and is located on interior holder, interior holder fixedly mounts at vacuum chamber inwall, the floating action of floating inner splint is promoted by connecting rod, connecting rod one end connects the inner splint that floats, the other end connects the push rod joint of heat-sealing push broach cylinder, external splint is fixed the float floating external splint of inner splint of the fixing external splint of inner splint and correspondence by correspondence and is formed, fixing external splint is fixedly located on pendulum plate, the external splint that floats floats and is located on pendulum plate.
The bottom of floating external splint is provided with floating clamping frame, the relative position floated between external splint and floating clamping frame is fixed, float and be articulated and connected by round pin between clamping frame and floating inner splint, before the action of heat-sealing push broach cylinder, round pin center and fork center are on same line of centers.
After adopting technique scheme, the present invention is simple and reasonable, opening that in vacuum chamber, unit presss from both sides is substantially identical with prior art with closing action, but seal push broach cylinder start to promote heat-sealing push broach cushion block carry out the heat sealing action of packing bag mouth time, first packing bag mouth can be carried out suitable tension by unit folder, so, no matter be the packaging bag that film thickness is very thin or sack width is larger, sack all can be smooth because of tension, would not be there is gauffer situation in such sack, thus improve vacuum packaging quality after carrying out heat sealing through hot knife.In technique scheme, when floating external splint swings with pendulum plate, the center of oscillation of floating external splint is center of oscillation and the round pin center of floating clamping frame in fact, but because round pin center and fork center are on same line of centers, so float, the center of oscillation of external splint is still centered by the center of fork, thus guarantee that the inside and outside clamping plate of unit folder are to the reliable grip of packing bag mouth, are also beneficial to the monolateral tension of unit folder to packing bag mouth.
As decision design, the bottom of the inner splint that floats is fixed with slide block, and interior holder is provided with chute, and skid is located in chute.
As decision design, the external splint that floats is provided with machine clamp pin axle, and pendulum plate is provided with elongated hole groove, and machine folder pin slide is located in elongated hole groove.
As decision design, the rotation of described fork in vacuum chamber by lower bearing support carry out pivoting support, upper branching holder near pendulum plate bottom arrange.Above-mentioned design can strengthen the support stiffness of fork, improves action stability when fork rotates.
