Abstract

The utility model discloses a wall paper foaming oven, which comprises an oven which is horizontally arranged along a longitudinal direction. Heat insulation layers are arranged on the four sides of the oven. A material film outlet and a material film inlet are respectively arranged at the front end and the rear end of the oven along the longitudinal direction. An upper group of air bellows and a lower group of air bellows which face to each other are installed in the oven along the moving direction of material films. Evenly arranged air outlet nozzles which face towards the material films are arranged on each group of air bellows. The two groups of air bellows are communicated with the outlet of a fan through a common air inlet pipe. A radiator is installed at an opening on the upper surface of one end of the oven. One outlet of the radiator is communicated with the inlet of the fan. A waste exhaust pipe is installed at an opening on the upper surface of the other end of the oven. The wall paper foaming oven has the advantages that the structure is more reasonable, the evenness of temperature on two sides of the oven is further improved by using the single fan for air supply, the heat loss is reduced because a hot air circulating system is not provided with a cooling air inlet, the temperature of the oven is increased rapidly and the oven is energy-saving and environmental-friendly.

Description

The wallpaper blowing oven

Technical field

The utility model belongs to the printing machinery technical field, is specifically related to a kind of wallpaper blowing oven.

Background technology

The wallpaper blowing oven is in wallpaper printing; With the device of the foaming of the PVC coated and dried on the wallpaper, this equipment is mainly used in various need the oven dry in the production line of material, and conventional device exists transverse temperature difference big; The thermal efficiency is low; The bigger problem that consumes energy causes inefficiency, has influenced product quality.

Summary of the invention

The purpose of the utility model provides a kind of wallpaper blowing oven, has solved to exist transverse temperature difference big in the prior art technical problem that the thermal efficiency is low.

The technical scheme that the utility model adopted is; A kind of wallpaper blowing oven comprises a longitudinally horizontally disposed baking oven, and the four sides of baking oven is provided with heat-insulation layer; Baking oven longitudinally front and back end respectively is provided with the export and import of expecting film; In baking oven, along material film trend two opposite groups blow box up and down is installed, every group of blow box is provided with towards material film evenly distributed and goes out tuyere, and two groups of blow boxs are communicated with the outlet of blower fan through blast pipe; One end upper surface open of baking oven is equipped with radiator, and another outlet of radiator is communicated with the import of blower fan, and baking oven is equipped with waste pipe.

The beneficial effect of the utility model is, transverse temperature difference reduces, and the thermal efficiency improves, and product quality improves, and realized the effect of energy-saving and emission-reduction.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.

With reference to Fig. 1, Fig. 2; The wallpaper blowing oven structure of the utility model is; Comprise a longitudinally horizontally disposed baking oven 9, the four sides of baking oven 9 is provided with heat-insulation layer 2, and baking oven 11 longitudinally front and back end respectively is provided with the export and import of expecting film; In baking oven 9, two opposite groups blow box 3 up and down is installed along material film trend; Every group of blow box 3 is provided with towards evenly distributed 8, the two groups of blow boxs of tuyere 3 that go out of expecting film and is communicated with the outlet of blower fan 4 through a common blast pipe 6, is provided with blast regulator 7 separately in the passage of two groups of blow boxs 3; One end upper surface open of baking oven 9 is equipped with radiator 5, and another outlet of radiator 5 is communicated with the import of blower fan 4, and the other end upper surface open of baking oven 9 is equipped with waste pipe 1.Arrow among the figure is that air or waste gas flow to.

The wallpaper blowing oven operation principle of the utility model is; The heat of the heated dry air in the baking oven 9 is delivered to the top of baking oven 9 through radiator 5; Blower fan 4 passes through blast pipe 6 with the heat that radiator 5 gives out; Circulating transfer is in blow box 3, and the tuyere 8 that goes out on the blow box 3 finally blows to material film upper and lower surfaces with hot blast, reaches the purpose of oven dry material film.Wherein the upper and lower surfaces of baking oven 9 and side all are coated with heat-insulation layer 2, guarantee that heat can not be dispersed into the baking oven outside; Waste pipe 1 is used for the useless cigarette that produces behind the heating material film is discharged baking oven, and blast regulator 7 is used for regulating two ends air intake size, guarantees that the blow box wind speed is even, thereby guarantees that baking oven both sides temperature is even.

The device of the utility model, structure is more reasonable, and the utilization of single blower fan air-supply further improves the uniformity of baking oven both sides temperature, and hot air circulating system does not have ad hoc cold wind air inlet, has reduced thermal loss, the fast and energy-conserving and environment-protective of baking oven programming rate.
