A kind of heat-circulation type cardboard drying baker
Technical field
The present invention relates to paper board processing equipment technical field, specifically a kind of heat-circulation type cardboard drying baker.
Background technology
Carton is made of the paper peace facial tissue combination of tooth form, in large-scale carton packed layer, or many modern furnitures
In often use the paper products inserts that tooth form paper is made, tooth form paper is first-selected by cutting and laminating, compose tabular, Ran Houke
To use.
, it is necessary to by cardboard by baking oven after tooth form quires is pressed into cardboard, so as to by the glue drying between tooth form paper,
It is firmly fixed together the tooth form paper for overlapping together.
Existing drying plant is fixed on drying chamber interior wall using heating wire, to being added by the cardboard in baking oven
Heat, and the glue for stacking is located inside tooth plate, it is not easy to it is heated to, so this mode of heating can not be directed to tooth form paper
Structure effectively dried, and be very easy to paperboard surface superheated, the drying effect to glue is reduced, while easily
Tooth form paper surface is scorched, makes tooth form curl.
The content of the invention
For the defect of above-mentioned technology, the present invention proposes a kind of heat-circulation type cardboard drying baker.
A kind of heat-circulation type cardboard drying baker, including oval housing, rear are provided with backboard, and housing front portion sets
There is front apron, material mouth was equipped with backboard and front apron.
The enclosure interior is provided with grillage, and the grillage is fixed in inner walls, is offered in the plate face of grillage
Hot hole, grillage upper surface is provided with electrical heating wire, and the electrical heating wire top is provided with the cardboard propulsion road being fixed on grillage, institute
State the propulsion wheel that cardboard propulsion road upside is provided with propulsion cardboard reach.
The left and right sides of the grillage is provided with a side shield by way of being hinged respectively, and the side shield can be around
It is hinged on the axis of rotation on grillage.
The case inside wall top is fixed with the heat backflow road for extending downward side shield upper edge, the heat backflow
Road extends to lower housing portion along housing insertion;Lower housing portion is installed with a blower fan, and the blower fan is towards diathermanous hole.
The rotating shaft of the side shield can on grillage front and rear play, the rear end of the rotating shaft is provided with spline structure, the plate
The rearward end of frame is fixed with the spline housing in the rotating shaft for being enclosed within respective side, and the front end of rotating shaft is fixed with through the front apron of housing and turns
Moving plate.
The propulsion wheel is connected with drive chain, and the drive chain is driven by motor.
The side shield is made of ceramic material.
The beneficial effects of the invention are as follows:
The present invention is heated from bottom using targetedly mechanical structure to cardboard, and heat is along the cardboard of tooth form
Gap, so as to heat is substantially passed into cardboard, improves emphatically the heating effect to the glue inside tooth form paper, and it is right to greatly improve
The drying effect of glue, while using thermal cycle mode, heat recovery is recycled, improves heat utilization efficiency, reducing energy consumption.

Specific embodiment
In order that the technological means realized of the present invention, creation characteristic, reached purpose and effect are easy to understand, below it is right
The present invention is expanded on further.
As shown in Figures 1 to 8, a kind of heat-circulation type cardboard drying baker, including oval housing 1, oval housing 1
So as to heat smooth flow, it is to avoid produce dead angle, the rear portion of housing 1 to be provided with backboard 2, the front portion of housing 1 is provided with front apron 3, keeps off afterwards
It is equipped with by the mistake material mouth 4 of cardboard on plate 2 and front apron 3.
Grillage 5 is installed, the grillage 5 is fixed on the inwall of housing 1, is opened up in the plate face of grillage 5 inside the housing 1
There is diathermanous hole 6, the upper surface of grillage 5 is provided with electrical heating wire 7, and the top of the electrical heating wire 7 is provided with the cardboard being fixed on grillage 5
Propulsion road 8, the upside of cardboard propulsion road 8 is provided with the propulsion wheel 9 of propulsion cardboard reach.
The left and right sides of the grillage 5 is provided with a side shield 10, the side shield 10 by way of being hinged respectively
Can be around the axis of rotation being hinged on grillage 5.
The madial wall of the housing 1 top is fixed with the heat backflow road 11 for extending downward the upper edge of side shield 10, described
Heat backflow road 11 extends to the bottom of housing 1 along the insertion of housing 1;The bottom of housing 1 is installed with a blower fan 12, the wind
Machine 12 is towards diathermanous hole 6.
The rotating shaft of the side shield 10 can on grillage 5 front and rear play, the rear end of the rotating shaft is provided with spline structure, described
The rearward end of grillage 5 is fixed with the spline housing 13 in the rotating shaft for being enclosed within respective side, and the front end of rotating shaft passes through the front apron 3 of housing 1
It is fixed with the rotation dish 14 for being easy to rotating shaft.
The propulsion wheel 9 is connected with drive chain (not shown), and the drive chain is driven by motor.
The side shield 10 is made of ceramic material, to improve the heat resistance of side shield 10 and heat insulating ability.
When using, by cardboard through the middle part of housing 1, and cardboard is advanced using frictional force using propulsion wheel 9, electrical heating wire
After 7 heating, heat, through the cardboard at the middle part of housing 1, glue is dried under the acceleration of blower fan 12, and the gas of heat passes through cardboard
On space after enter into heat backflow road 11, and being located at the side shield 10 of both sides is then used to limit heat, makes heat stream
To heat backflow road 11.The blower fan 12 forms negative pressure in the heat backflow bottom of road 11, so that the heat on the heat backflow top of road 11 is smooth
It is back to bottom.
General principle of the invention, principal character and advantages of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not limited to the above embodiments, the simply present invention described in above-described embodiment and specification
Principle, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these change and
