Description

Inflation film coats drying unit

Technical field

The utility model belongs to plastic film processing machinery field, coats drying dress more particularly to a kind of inflation film It sets.

Background technique

Film Blowing Process in well-known technique, the material of molten are squeezed out from mold (head) and are propelled the price of, by Conduction enters thin film winder still further below after upper traction.On the basis of blown film, use paint-on technique for the newest of current agricultural film Technique.After film conducts downwards, it is submerged initially in liquid tank, function additive is coated in film surface layer, is equipped with number row's temperature along two sides Implement drying in 80 DEG C of quartz ampoule constent temperature heaters and air blower.Since drying cabinet uses leveled heating and air blast form, Heating heating device excessively disperse, integral heat insulation and the sealing effect for drying cabinet are undesirable, cause thin film coated layer cannot and When dry, and drying effect is undesirable, causes coat not to be stained with securely with film completely and is integrated, function additive and water It mixes.When by upper traction clamp roll, part coating powders are stained on nip rolls, and then affect the function of film product.In addition, by Leveled heating and air blast form are used in cabinet, not only structure is complicated, waste of energy and space, and constructs and attended operation is numerous It is trivial.

Summary of the invention

The utility model is to solve technical problem present in well-known technique and provide a kind of inflation film coating drying dress It sets, which can make coat sufficiently dry, guarantee thin film coated drying effect, realize firm with film after the auxiliary agent of coating is dry Admittedly be stained with and be combined；Space utilization rate is improved, reduces production cost and convenient for construction and attended operation.

The utility model is adopted the technical scheme that solve technical problem present in well-known technique:

Inflation film coating drying unit, cabinet, heating mechanism and centrifugal blower including the affixed composition of multiple drying boxes, It is characterized by: the cabinet is upper on the outside of the drying box two of lower part to be equipped with mutual corresponding heating mechanism, the heater It is connected with the air compartment in drying box on the inside of structure, centrifugal blower is housed on the outside of the heating mechanism, on the inner wall of cabinet Equipped with fire protection flame retarding insulation board and baffle plate.

The utility model can also adopt the following technical scheme that

The cabinet is upper on the outside of the drying box two of lower part to be equipped with the two groups of heating mechanisms corresponded to each other in being arranged above and below.

The air compartment in the drying box is fixed with filter screen in the border the great Kou portion of air compartment in pyramidal.

Sawtooth is formed on the surface of the baffle plate.

The utility model has the advantages and positive effects of: by adopting the above technical scheme due to the utility model, that is, drying Dry cabinet concentrates heat blowing form using lower part, increases Unit heating and air quantity output frequency, and in drying cabinet setting two The insulation board and baffle plate of side seal, rising cold suction decline principle and baffle plate using hot-air more can sufficiently make hot wind Circulation repeatedly utilizes, and insulation board keeps heat losses slack-off, not only ensure that and reach good coated in the coat on thin-film body Effect is air-dried, the quality of film product is increased substantially, reduces consumption, saves equipment occupation space；And convenient for construction and Attended operation.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the side view of Fig. 1.

In figure: 1, drying box；2, heating mechanism；3, centrifugal blower；4, baffle plate；5, fire protection flame retarding insulation board；6, it filters Net；7, air compartment.

Specific embodiment

For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates Detailed description are as follows for attached drawing:

Please refer to Fig. 1 and Fig. 2, inflation film coats drying unit, cabinet including the affixed composition of multiple drying boxes 1 plus Heat engine structure 2 and centrifugal blower 3, the cabinet is upper on the outside of the drying box two of lower part to be equipped with mutual corresponding heating mechanism 2, institute The air compartment 7 being connected in drying box on the inside of heating mechanism is stated, centrifugal blower 3 is housed on the outside of the heating mechanism, in case The inner wall of body is equipped with fire protection flame retarding insulation board 5 and baffle plate 4.

In the present embodiment, the cabinet is in be arranged above and below equipped with corresponding to each other on 1 liang of outside of drying box of lower part Two groups of heating mechanisms 2.

In the present embodiment, the air compartment 7 in the drying box is fixed with double in pyramidal in the border the great Kou portion of air compartment The filter screen 6 of layer, the filter screen use the stainless steel filter screen of 40 mesh and 60 mesh.By installing filter screen, it can not only make heat Wind is uniformly spread, and avoids the intracorporal local wind of case excessive；And the impurity will in air may also be filtered, it is thin to prevent stopping loss wound Film.

In the present embodiment, sawtooth is formed on the surface of the baffle plate 4, the sawtooth tilts upwards.

The working principle of the utility model are as follows:

The film for immersing drying course after liquid tank coats is pulled up among a pair of of constant temperature dehydration facility, by drying The heating mechanism 2 of case 1 and the heated at constant temperature of air compartment 7 increase Unit heating and air quantity are defeated in this way using heat blowing form is concentrated Frequency out eliminates the moisture content of thin-film body substantially.Wind is blown into air compartment 7 by centrifugal blower, is risen using hot-air, cold air The principle of decline, while baffle plate being cooperated more sufficiently hot air circulation to be made repeatedly to utilize, it is slowed down using fire protection flame retarding insulation board 5 Heat losses.It not only ensure that and reach good air-dried effect coated in the coat on thin-film body, increase substantially film production The quality of product reduces consumption, saves equipment occupation space；And convenient for construction and attended operation.

Embodiment described in the utility model attached drawing is exemplary, and is only used for explaining the utility model, and cannot be managed Solution is limitations of the present invention.
