The utility model is described further combined with specific embodiments below, however persons familiar with the art should
Solution, is to preferably explain here in connection with the detailed description that attached drawing provides, the structure of the utility model has necessarily had exceeded
These embodiments of limit, and for some equivalents or common approach, it is no longer described in detail herein, but still fall within this
The protection scope of application.
As shown in Fig. 1 ~ 4: platform 4 is arranged at intervals on equal 5 downside of bellows, and the two sides of equal bellows 5 are symmetrically arranged with briquetting 2,
Briquetting setting is between platform 4 and bellows 5.The downside of equal bellows 5 is provided with horizontal gas outlet 501, gas outlet 501 and flat
The upper parallel of platform 4 is arranged, and the spacing of the upside of gas outlet 501 and platform 4 is less than or equal to 1cm, and gas outlet 501 is avoided to blow out
Hot wind diffusion lead to heat loss, and then influence heat-sealing effect.Briquetting 2 can also be not provided between equal bellows 5 and platform 4.
Each briquetting 2 is coated with teflon cloth, sticks together after being heated so as to avoid briquetting 2 and plastic foil, influences plastics
The heat-sealing of film, and influence the quality after heat-sealing.The coincidence part of plastic foil can either be sealed, and can be avoided in plastic barrel
There is the problem of adhesion.
After the color closed at both ends of equal bellows 5, the top of equal bellows 5 is horizontally disposed cylindrical shape, the lower part of equal bellows 5
Two sides are the taper that from top to bottom width is gradually reduced, to form gas outlet 501 in the downside of equal bellows 5.The two of equal bellows 5
End downside is the rake by end to middle part gradually downward, and two rakes of equal bellows 5 close setting, can be guaranteed whole
The hot wind that a gas outlet 501 is blown out is uniform.
Hot air pipe 1 is opening up " Contraband " shape, and the length of the vertical portion of hot air pipe 1 is less than the length of equal bellows 5, and big
Length in gas outlet 501.The vertical portion of hot air pipe 1 is co-axially located at the top of equal bellows 5, and the both ends of hot air pipe 1 are upward
Tank wall and stretching across equal bellows 5, hot air pipe 1 and equal bellows 5 are tightly connected.It is spaced on the tube wall of the vertical portion of hot air pipe 1
Multiple ventholes 101 are provided with, 1 inner cavity of hot air pipe is connected to by venthole 101 with equal 5 inner cavity of bellows, makes the hot wind in hot air pipe 1
It uniformly enters in equal bellows 5, and then the hot wind for guaranteeing that gas outlet 501 is blown out is uniform.
The upper end of two horizontal parts of hot air pipe 1 is bent outward respectively, forms horizontal docking section, and a docking section is used
In connection hot wind air inlet pipe, another docking section is for connecting hot wind escape pipe.It is provided with valve on two docking sections, thus
Facilitate the flow velocity of hot wind in control hot air pipe 1, and then facilitates the speed of the hot wind of the blowout of control gas outlet 501.Gas outlet 501
The temperature of the hot wind of blowout is 120 ~ 190 DEG C, and the wind pressure in bellows 5 is 0.2 ~ 0.4Mpa, by adjust hot air pipe 1 two
The wind pressure in equal bellows 5 is adjusted in the valve of a docking section, and then the hot wind for adjusting gas outlet 501 blows out speed, adjusting side
Just.The hauling speed of plastic foil is 40 ~ 120m/min, to guarantee to seal effect, can either avoid bonding loosely, and can be avoided
It seals overlong time and damages plastic foil.
Hot air pipe 1 is coated with insulating layer 3, and insulating layer 3, the top of equal bellows 5 are stretched out in two docking sections of hot air pipe 1
It is arranged in insulating layer 3, to avoid heat-sealing temperature in hot air pipe 1 from reducing, and then convenient for controlling the hot wind that equal bellows 5 are blown out
Temperature, guarantee temperature uniformly and stablize.
Two briquettings 2 gradually lean outward from the bottom to top close to the side of equal bellows 5, the i.e. adjacent side of two briquettings 2
Tiltedly setting so that the spacing of two briquettings 2 be made to be gradually increased from the bottom to top, and then guarantees extra hot wind by two briquettings 2
Inclination side flows away, and guarantees the hot wind even width blown on plastic foil, and the width for the hot wind for facilitating control to blow on plastic foil
Degree, and then facilitate the width in the heat-sealing portion on control plastic foil.Spacing of two briquettings 2 close to the side of platform 4 is 1 ~ 5mm,
So as to control plastic foil heat-sealing portion width.
The downside of briquetting 2 and the upside interval of platform 4 are arranged, and the upside of each briquetting 2 is respectively connected with distance regulating mechanism,
In the present embodiment, distance regulating mechanism is vertically arranged cylinder 6, and cylinder 6 and briquetting 2 correspond, and cylinder 6 is arranged right
2 upside of briquetting of side is answered, the piston rod of cylinder 6 is connected with briquetting and briquetting 2 is driven to go up and down, to adjust briquetting 2 and platform 4
Spacing.Distance regulating mechanism can also use oil cylinder or electric pushrod.
When being sealed using this polybag or plastic tube heat-sealing device to plastic foil, plastic foil is placed on 4 downside of platform,
In the two sides of plastic foil are folded upward at and are coated on platform 4, and two side superimposeds of plastic foil and be arranged briquetting and platform 4 it
Between interval in, draw plastic foil and advanced with the speed of 40 ~ 120m/min, while being passed through hot wind in hot air pipe 1, and guarantee equal wind
Pressure in case 5 is 0.2 ~ 0.4Mpa, and the temperature of hot wind is 120 ~ 190 DEG C, thus under conditions of realizing that plastic foil continuously moves
Heat-sealing, heat-sealing effect are good.Plastic foil can be PE film, can also be other plastic foils.
