Vertical type vacuum packing machine

Abstract

This invention relates to a vertical type packing machine, in which film-bag delivering, material feeding, evacuation and film-bag sealing processes are conducted in vertically conveying mode, wherein the object to be packed, after weight control through the weighing device, is fed into the vacuum packing device through an inlet hopper having a packing film-bag inserted from the top end thereof, the packing film-bag being cut by a primary cutting section of a blade set in the primary mould-closing state of the vacuum packing device so as to make a bag-opening, the air within the film-bag being exhausted to ambience by the evacuation process conducted in complete mould-closing state, simultaneously the bag-opening of the precedent packing film-bag and the bottom of the subsequent packing film-bag being sealed separately, then a cutting process being conducted between the sealed bag-opening of the precedent packing film-bag and the sealed bottom of the subsequent packing film-bag by a secondary cutting section of the blade set, finally the mould being opened so that the vacuum packing of the material delivered in vertical direction is completed.

1 . A vertical type packing machine, essentially comprising:
 a material incoming device, which is a inlet hopper provided on the upper side of the frame-base for delivering object to be packed, said inlet hopper having a delivering channel therefrom;   a weighing device oppositely disposed at the upper side of the inlet hopper for weighing the feeding object to be packed each time;   a film-bag delivering device which is a film-bag roller provided on the frame-base, the film-bag roller introducing a packing film-bag to the inlet hopper for accommodating the weighed object to be packed;   a vacuum packing device oppositely disposed at the lower side of the material incoming device for receiving the packing film-bag already filled with object to be packed, which essentially is provided with a case body having a left half and a right half capable of closing with each other, an evacuation device being provide within the case body which is also provided with a blade set having a primary cutting section for produce a bag-opening and a secondary cutting section for severing, a first sealing blade for sealing the bottom of the subsequent packing film-bag and a second sealing blade for sealing the bag-opening of the precedent packing film-bag being provided at the upper and lower ends of the blade set respectively.   
     
     
         2 . A vertical type packing machine as claimed in  claim 1 , wherein said blade set has, on the blade, a primary cutting section for produce a bag-opening of the packing film-bag and a secondary cutting section for the severing of the packing film-bag 
     
     
         3 . A vertical type packing machine as claimed in  claim 1 , wherein said blade set has a primary cutter directed for producing the bag-opening and a secondary cutter directed for the severing of the packing film-bag. 
     
     
         4 . A vertical type packing machine as claimed in  claim 1 , wherein a sensor for sensing the entry of the packing film-bag into the case body is provided on the case body of the vacuum packing device. 
     
     
         5 . A vertical type packing machine as claimed in  claim 1 , wherein said material incoming device is provided with more than one inlet hopper and the film-bag delivering device introduces corresponding numbers of the packing film-bag with respect to the quantity of the inlet hopper. 
     
     
         6 . A vertical type packing machine as claimed in  claim 1 , wherein a vibratory mechanism is provided in the case body of the vacuum packing device, which produce vibration on a disk body driven by a power source for abutting with the object to be packed. 
     
     
         7 . A vertical type packing machine as claimed in  claim 1 , wherein said weighing device is a flow rate detection meter. 
     
     
         8 . A vertical type packing machine as claimed in  claim 1 , wherein said weighing device is a timer. 
     
     
         9 . A vertical type packing machine as claimed in  claim 1 , wherein said weighing device is a scale. 
     
     
         10 . A vertical type packing machine as claimed in  claim 3 , wherein said primary cutter of said blade set is a needle shape design.
