Abstract
The utility model relates to a heating furnace used for shrinkable film packing. Because the utility model adopts the complex layout forms of the downward arrangement of a blower, the central heating, an adjustable air door and the downward arrangement of an air outlet, the structure is particularly compact and reasonable.
Description
The utility model relates to a kind of holding tray shrinking packaging that is used for heat-shrinkable film is heated the heating furnace that makes its contraction, is in the utility model (patent No.: the 922180113) improvement of carrying out on the basis that the inventor has invented.
In above-mentioned patent, adopted the hot air circulating oven of double air passage bottom air draught type.Place the blower fan at heating furnace top, will after in mixing chamber, mixing, enter interior air flue through being arranged in four strands of thermal currents that temperature does not wait after four groups of heating element heaters heating in four side angles fall in the exterior air drain of furnace wall.Mixed thermal current, via several sizable upper wind doors and the crosswind door on the interior air flue inwall, after blowing to the packing workpiece that is with heat-shrinkable film in the burner hearth, discharge, enter the exterior air drain that four groups of heating element heaters are housed and circulate more than by the inlet scoop of burner hearth below.Though this kind structure obtains good packing and ties up performance, because of putting on the blower fan, and, make heating furnace structure compact inadequately because heating element heater is divided into four groups, maintaining is convenient inadequately.
It is more reasonable, compact that the purpose of this utility model provides a kind of structure, and the also more good double air passage bottom air draught type hot air circulating oven of performance is tied up in shrink wrapping.
Fig. 1 is its fundamental diagram, and arrow is represented thermal current among the figure.
Describe structure of the present utility model and working condition in detail below in conjunction with Fig. 1.
This heating furnace comprises the furnace wall, has fire door before and after the furnace wall, makes the turnover of packing workpiece.Be installed on the blower fan 1 in heating furnace bottom or the furnace sidewall, after the air-flow that burner hearth bottom inlet scoop 8 is discharged boosts, deliver to the heater 3 (heating of heating wire, electrothermal tube or other equivalent effect) that is installed in the outer exterior air drain 2 of furnace sidewall or stove.Be admitted to exterior air drain through the thermal current after the heater heating, enter the interior air flue 6 that constitutes by between furnace wall 4 and the double wall 5 by the furnace roof top again, and by several sizable upper wind doors and crosswind door 7 on the interior airway walls, blow to the workpiece 9 that is with shrinkable film in the stove, discharge by the inlet scoop under the burner hearth 8 again.The air-flow that flows out from the inlet scoop enters the blower fan air intake vent again, and circulation is more than.
Compare with existing technology, the utlity model has following advantage:
1. because no matter moving component underlyings such as blower fan are to place furnace bottom or furnace side, body of heater stability is improved, equipment lightness, structure are more compact.
2. blower fan places the front side of heater, and the condition of work of blower fan is made moderate progress, and power consumption also decreases.
3. adopt and concentrate heating, no matter heater is to place stove interior as a whole with structure of furnace body, still heater is placed the outer independent independently parts that form of stove, it is more flexible, compact that entire equipment is arranged, owing to concentrate heating that computer-controlled controlling unit has been reduced, can also make the hot stream temperature that enters in the stove more even simultaneously.
Claims (3)
1. film shrink wrapping heating furnace, this stove is by the furnace wall 4 of fire door before and after being provided with, underlying be installed on blower fan 1 in heating furnace bottom or the furnace sidewall, heater 3, the double wall 5 of centralized arrangement in exterior air drain 2 formed, air flue 6 in it is characterized in that constituting between furnace wall 4 and the double wall 5, several sizable upper wind doors and crosswind door 7 are arranged on the interior air flue inwall, offer the inlet scoop under the burner hearth.
2. heating furnace according to claim 1 is characterized in that: the blower fan underlying can place in furnace bottom or the furnace sidewall.
3. heating furnace according to claim 1 is characterized in that: adopt concentrated heat form, after heater places the blower fan outlet.
