Abstract

This invention relates to an adjustable compression closing means, which includes ballast, upper bear, bearing wedge, bar, and fixed bear, the pressure output shaft of the ballast connects with the roll on one end of the bar, the other end of the bar supports the upper part of the bearing wedge, the bottom of the bearing wedge forms the rolling bear with the upper bear, and the bearing wedge can slide on the alley which forms from the upper bear, and it forms a fixed distance pressure space with the fixed bear. This invention uses the bar and the wedge to do two level mechanical pressurizing, wherein it can produce enough close force to achieve the instant load, and using the spring to pressurize amortizes the huge reaction force that is produced by small change and go back near to the normal working place. And this invention can achieve the grip guiding through the bearing wedge and the roller guide-channel that is on the fixed bear.

Description

Pressure adjustable pressurizing and sealing device

Technical field

What the present invention relates to is a kind of pressure device of field of mechanical technique, particularly a kind of pressure adjustable pressurizing and sealing device.

Background technology

Aseptic packaging (Aseptic Packaging) is present more common a kind of liquid food packing preservation technology.It is meant that packaged liquid food passes through the sterilization of short time before packing, carry out a kind of packing technique of can, involution then under all aseptic condition of packing (generally being the packing that are composited by polyethylene, paper, aluminium foil, sarin resin etc.), packed article, packaging facilities and pack environment.As everyone knows, the above-mentioned can involution process of introducing can be divided into: packing enter in the sterile sealing storehouse through after disinfecting, be formed by belt-like form and be longitudinally sealed in straight cartridge form by formation system, food liquid is delivered directly in the straight tube by delivery duct through pasteurization or uht (UHT) back, be cut to inner wrapping then at the lateral part of spaced at equal intervals back seal, and at the transverse sealing position.

The continuous canning means of normal employing in high-speed canning, two chain type motion assemblies define corresponding circulating path and many heating member and pressing means to jaw are housed respectively.These two paths comprise relative and parallel individual path, and between feeding packaging material paper web.Heating jaw pressurization jaw in the branch in the described individual path of respective paths and another path cooperates, clamps also involution paper web one group of transverse part office in proper order.In above-mentioned technological process, processes such as pressurization, involution, cut-out are to be full of under the situation of liquid beverage to finish in cylindric straight tube container, and filling apparatus is often at a high speed and require to move under the state of high reliability, and pressure device must be stablized pressurization to the straight tube that liquid beverage is housed in the short time at the utmost point.This pressure must be enough to extrude the liquid beverage between the packing and form enough involution pressure.Because said process pressed object successively to move, and requirement can have certain buffering to adapt to and automatic small adjustment the microsize of object, has adjustability simultaneously.

Find by prior art documents, Chinese invention patent application number 98115128, name is called: the continuous irrigation assembling device, this technology comprises that decide unit frame by two sidewalls and two transverse walls has installed two pairs of general chain exercise group parts in form, the packaging material paper web passes from the middle opening that two pairs of general chain exercise group parts form, comprise the heating jaw and the pressurization jaw that cooperatively interact on the two pairs of general chain exercise group parts, by the induction heating plant on the heating jaw at continuous transverse part office heat-sealing tube.Jaw guiding adopts the cam slave state, the contact front portion of cam a contact angle feature arranged, be convenient to enter by the nip territory when paper web.For guaranteeing that roller contacts with this cam on the jaw, disposed chain tensioning device.Designed the cross joggle piece on one-sided limit when pressurization jaw and heating jaw involution, this device jaw guiding adopts the cam slave state, and has disposed chain tensioning device, makes the variation of chain mode of operation greatly.The pressure that is scattered in each pressurization jaw adjusts that not only adjustment process is long, and conformability is poor.
