Plate 34 is two pieces, and two pressure plates 34 are abutted with the both ends of cross bar 32 respectively;Third fastening screw 07 connects stand 33 and pressing plate 34
And fastened by third fastening nut 08, for cross bar 32 to be fixed on stand 33.Band transmission unit further includes being set in conveyer belt 2
Driving wheel, driven wheel, and driving driving wheel rotation rotary power part.Rotary power part is motor.Pressure roller 31 and cross bar
Bearing is equipped between 32.Bearing is two, is respectively arranged on the both ends of cross bar 32.The external cylindrical surface of pressure roller 31 is metal cylinder.Pressure roller
31 include rubber roller, and rubber roller is set to cross bar 32 by bearing holder (housing, cover), and metal cylinder is sheathed on rubber roller and the two is fixedly linked.
In the application, it is connected through a screw thread part and stand 33 is fixed on support 1.Specifically: it is adjusted by being set to first
Threaded connector at hole 331 and the threaded connector at the second adjustment hole 332 consolidate stand 33 from two different directions
It is fixed, guarantee that a kind of food bag automatic flattening press of the application after long-term operation, is still able to maintain firm.First adjustment hole, 331 He
Second adjustment hole 332 is that the structure in rectangle or long waist shaped hole is conducive to the adjusting of 33 height of stand.When needing to adjust pressure roller 31
When the distance between conveyer belt 2, it can be realized by adjusting the height of stand 33.Specific adjustment process are as follows: by unclamping first
Fastening nut 03 and the second fastening nut 06, are adjusted the relative altitude of stand 33 with support, to adjust pressure roller 31 and transmission
The distance between band 2 is adapted to the packaging bag 4 of different-thickness.First adjustment hole 331 and the second adjustment hole 332 are in food bag
It is arranged in a staggered manner in the short transverse of automatic flattening press.On the one hand the design is conducive to reduce influence of the aperture to 33 intensity of stand,
On the other hand, so that fixed position is staggered, be conducive to firm fixed stand 33.33 structure of stand of hollow structure is conducive to loss of weight, rectangle
33 structure of column stand is conducive to provide smoothly installation supporting surface.In the application, the first backing plate 02 and the second backing plate 05 are length
Square plate, the design are conducive to it and support stand 33, bear the coupling mechanism force of the first fastening nut 03 and the second fastening nut 06.First
The length of backing plate 02 and the second backing plate 05 is to consistent with a kind of short transverse of food bag automatic flattening press of the application, the design
Conducive to the first backing plate 02 and the setting concordant with stand 33 of the second backing plate 05 is made, makes compact overall structure, eliminate because of the first backing plate
02 causes to scratch the security risk of related operating personnel to 05 evagination of the second backing plate.The pressure of cross bar 32 is set to by pressing plate 34 and is stood
Frame 33 recycles third fastening screw 07, third fastening nut 08 that cross bar 32 is fixed on stand 33, which is conducive to assembling.
It is rubber roller inside pressure roller 31 in the application, is conducive to loss of weight and reduces equipment cost, be metallic roll outside pressure roller 31, surface is smooth,
Conducive to force of rolling friction is reduced, bag pressing effect is improved.Bearing between pressure roller 31 and cross bar 32, be conducive to pressure roller 31 and cross bar 32 it
Between flexible rotating, when motor drive driving wheel, driven wheel to drive conveyer belt 2 move when, on conveyer belt 2 equipped with food
The food bag of product follows conveyer belt 2 mobile and advances to the direction close to compression roller unit 3, when by compression roller unit 3, food bag
Top contacted with the metallic roll of the pressure roller 31 in compression roller unit 3, force of rolling friction is generated between food bag and pressure roller 31, at this time
The lower part of food bag is still contacted with conveyer belt 2, due to having had been loaded into food in food bag, has certain self weight, therefore
There is enough force of sliding frictions between the lower part and conveyer belt 2 of food bag.When design, it need to guarantee that the value of force of sliding friction is greater than
The value of force of rolling friction, when so ensuring food bag by pressure roller 31, substantially without relative motion, food between conveyer belt 2
The top energy band dynamic pressure roller 31 of bag rolls.At this point, pressure roller 31 generates downward rolling power to food bag, the fold of food bag is rolled
It is flat.Food bag after the rolling of pressure roller 31 follows conveyer belt 2 to continue to flow into next process, completes automatic pressing operation.It needs
Illustrate: when design, need to rationally adjust the gap width between pressure roller 31 and conveyer belt 2, which need to guarantee to be greater than food
The maximum gauge value of bag state of applanation so guarantees that food bag can pass through;The gap width also needs to guarantee to be less than food bag pleat
The maximum gauge value of corrugation state, when so can guarantee food bag by pressure roller 31, pressure roller 31 can roll the food bag of fold
Pressure, fold is flattened.Specific gap width can be according to the weight of food, pressure roller 31 rotate in food bag flexibility ratio, conveyer belt 2
The actual conditions such as coefficient of friction are adjusted.
Compared with the relevant technologies, the application can be real in food packaging by setting compression roller unit above tape transport system
Now automatic bag pressing operation, food bag is flattened, then flow into next procedure.Production efficiency is improved, saves manually, reduces
Whole production cost.
