Operation principle:By plastic film tube 200 sleeve in plastic foil reel support roller 140, and pass through two fairleads 141
Carry out two ends spacing, then, the film of plastic film tube 200 pulls downward on to polybag forming tube 2 and along being vertically directed pipe 25
Move down, the film of plastic film tube 200 carries out bending so that two ends are closed around polybag forming tube 2 with being vertically directed pipe 25
And locate to carry out moving after heating merges and being clamped between the first pinch roller 281 and the second pinch roller 283 by two heat blocks 214;
Operation conditions between first pinch roller 281 and the second pinch roller 283 is the second pinch roller 283 is to rotate turning handle by hand
Hand 233, so that rotating bar 234 rotates, catch bar 235 is lifted up, so that the first pinch roller 281 and the second pinch roller 283
Mutually it is not pressed against, and be rotated further by swing handle 233 so that push-jump lever 234 is no longer press against catch bar 235 so that under catch bar 235
Drop back to position, now, the first pinch roller 281 is mutually pressed against with the second pinch roller 283, wherein, the front end of the output shaft of the first rotary electric machine 28
It is fixed with the first pinch roller 281, the rear end of the output shaft of the first rotary electric machine 28 is fixed with the first drive, rotates block 282
Output shaft be fixedly arranged at the front end with the second pinch roller 283, the rear end rotating the output shaft of block 282 is fixed with driven pulley, the first transmission
Wheel is mutually pressed against with driven pulley and realizes transmission by frictional force, thus realizing 283 relative turns of the first pinch roller 281 and the second pinch roller
Dynamic;
Then move to foot, run by two heating cut-out blocks 227, the lower end of film is cut away, simultaneously so that
Sealing is melted in the bottom of film, so that the bottom of film is shaped to the polybag of three-side-sealed, polybag is in weighing plate
On 103, then, powder is poured in feeding warehouse 14, be fixed on the control of frame 100 in the control main frame control main frame of this device
After the middle setting data such as weight parameter on plate, pass through during some warming-up exercises before the operation of its middle front part of unlatching equipment description
Artificial control is carried out, and its concrete principle is identical with the automatic principle describing below, is not described in detail.
First, screw drives stepper motor 12 run so that feeding spiro rod 121 rotate (its turning collar several according to set into
OK), material is carried out being delivered to discharge nozzle 1, wherein, conveyed by feeding spiro rod 121 so that its delivery precision is high, weight is accurate
Really, and blanking is stable;The material of discharge nozzle 1 enters polybag forming tube 2 and enters under film along being vertically directed pipe 25
In the polybag of three-side-sealed of end shaping, now, the weighing plate 103 on weight transmitter 104 pushes, thus obtaining weight
(rotating several weight enclosing blanking by feeding spiro rod 121 is to record weight by weight transmitter 104, thus control main frame
Record its weight), meanwhile, motor 221 runs, so that vertical drive link 26 carries out eccentric rotary so that two are above heated
The front end of bar 211 and lower heating pole 226 is homogeneously drawn close so that two heat blocks 214 are pressed against the first pinch roller 281 and the second pinch roller
The downstream of the film of 283 tops carries out heating and melting phase and glues, and simultaneously, two heating cut-out blocks 227 are mutually drawn close so that thin
The bottom of film is between two heating cut-out blocks 227, and two heating cut-out blocks 227 are mutually pressed against so that having heater strip 35
Heating cut-out block 227 retreats, and two guide rods 32 and heater strip 35 enter the corresponding secondary heating of another heating cut-out block 227
In groove 37, by heater strip 35 and heating plate 380, film bottom is cut off, so that the polybag of the three-side-sealed of bottom
Top seal complete to pack, promoted by scraping wings 228 meanwhile, packaged product released, complete to pack, then, the
One pinch roller 281 and the second pinch roller 283 run, and by film drag down, meanwhile, film that top heating and melting phase is glued is to moving down
Move between the first pinch roller 281 and the second pinch roller 283, because the first pinch roller 281 is mutually pressed against with the second pinch roller 283, so that
The lower end of film is molded the polybag of new three-side-sealed so that this polybag is on weighing plate 103, and remaining is same as above,
Thus realizing follow-up packaging, pack in this way successively, very convenient.
Meanwhile, electric heating fan can be fixed with the rear portion top surface of lower horizontal board 22 as needed to be radiated.
Finally, embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, relevant technical field
Those of ordinary skill, without departing from the spirit and scope of the present invention, can also make a variety of changes and modification, therefore
All equivalent technical schemes fall within scope of the invention, and the scope of patent protection of the present invention should be defined by the claims.
