Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage be more easily understood, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.

Such as Fig. 1-4, a kind of hot blast packaging shrinker, including body 11, the heating chamber 13 with heater, self-heating chamber 13 entrances 131 are to exporting 132 conveyer belts 3 being radially arranged, being arranged at heating chamber 13 entrance 131 and the chiller of outlet 132 5, some blower fans 6, operating board 12, its heating medial wall, chamber 13 is symmetrical set the wind deflector that energy is upper and lower, left and right guides air-flow, Described wind deflector is arranged at conveyer belt 3 left and right sides, and wind deflector does not contacts with each other with the inwall heating chamber 13；Described adds Thermal is symmetrical set between heating chamber 13 sidewall and wind deflector；Described blower fan 6 is arranged at below heater, and The air-flow outbound course of blower fan 6 is from wind conduit below left and right heater the most respectively, wind deflector and left and right heating to left and right The air channel enclosing formation between the inwall of chamber 13 is transmitted to the direction of heating chamber 13 inner roof wall.

In the present embodiment, as Fig. 2,5, in order to improve wind deflector up and down, left and right guide the effect of air-flow, described wind-guiding Plate includes that framework 21, some guiding wind-engaging blades 23 up and down and some left and right guide wind-engaging blades 22, and described guiding up and down is drawn Air blade 23 and left and right are guided wind-engaging blades 22 and can be overturn around framework about 21, left and right by rotating shaft respectively, guide air-flow respectively Upper and lower, left and right flow to, under folded position, adjacent guide between wind-engaging blades 23 up and down and adjacent left and right guides air inducing Blade 22 can mutually cover；The blade end of the blade end and left and right guiding wind-engaging blades 22 that guide wind-engaging blades 23 up and down divides Do not extend to contrary both sides from framework 21.

Such as Fig. 5, enclosed the air channel of formation, the gas of blower fan 6 conveying by heating 13 medial walls, chamber-heater-wind deflector Stream along air channel to the inner roof wall conveying of heating chamber 13, and can carry to conveyer belt 3 from roof, thus adds the roof position of hot product； Thermal current transmits to conveyer belt 3 from wind deflector, adds the sidewall position of hot product, by regulating upper and lower, the left and right air-flow of wind deflector Flow to, while have adjusted air flow direction, it is also possible to limit the flow velocity of air-flow.

Described heater is the electrothermal tube 4 of tubulose, and self-heating chamber 13 entrance 131 is uniformly arranged to outlet 132, makes to add Steam effect in hot chamber 13 is more uniform.

Such as Fig. 4, described conveyer belt 3 is roller type conveyer belt 3, and the roll surface 31 of each roller bearing is outside is coated with high-temperature fibre Pipe 32, two ends, axle portion 34 cladding high temperature resistant silicon sebific duct 341.Roller type conveyer belt 3 has stable laser propagation effect, the roll surface of roller bearing 31, the exotic material of axle portion 34 cladding can promote the resistance to elevated temperatures of roller bearing.

For the operating function of further lifting operation platform 12, except blower fan 6, conveyer belt 3, heater, chiller 5 Switch outside, described operating board 12 has that wind frequency control transported by blower fan 6, conveyer belt 3 transmits frequency control, gradient of temperature control System, emergency stop switch function.

In order to further ensure heats, and it is too high to prevent heating chamber 13 outside wall temperature, described heating chamber 13 Heat-barrier material it is filled with inside cavity wall.When using heat insulation cord, can reduce heat losses, heat insulation effect is good, is greatly reduced Heat energy loss.

When product completes contraction process in heating chamber 13, by the inspected heating chamber arranged in the cavity wall in heating chamber 13 Visual windows within 13, can be observed the overall process that product shrinks, it is simple to rationally set according to the contraction situation of product heat shrinkage film Put the relevant parameter such as heating-up temperature, fortune air quantity, improve the packaging effect of heat shrinkage film.
