Abstract
The invention discloses a heating device of plastic sheet (plate) thermal molding machine, which comprises: a box (1) whose bottom is formed by reflecting plates and an infrared radiator (3) is mounted under the reflecting plate (2). In addition, the reflecting plate, the relative infrared radiator and its two ends are all mounted with tube heat emission holes (4), tube-end heat emission holes (5); the upper part of said box (1) is mounted with heat emission fan (6) and relative intakes (7); the wind blown by the heat emission fan via said intake enters into the box; and the heat out of said infrared radiator via itself emission and the reflection of reflecting plate are transmitted to the plastic sheet (plate), and spread from the surface to bottom to heat and soften the plastic sheet quickly. The invention has the advantages that: quick energy transmission speed, better heating effect, improved heating effect and saved electricity.
Description
One, technical field
The present invention relates to a kind of plastic sheet (plate) sheet (panel) hot-forming that plastic sheet or sheet material are carried out thermoforming (utilizing malleation, negative pressure or mold pressing principle), specifically relate to the heater that a kind of plastic sheet (plate) sheet (panel) hot-forming is used.
Two, background technology
Existing plastic sheet (plate) sheet (panel) hot-forming can be divided into plastic tab, sheet thermoforming machine, have functions such as feeding, heating, moulding, cooling, the demoulding, stamping-out, can finish whole operations of plastic sheet or plate thermal forming, extensively utilize plastic sheets such as PVC, PET, PS, PP, ABS, acrylic, sheet material to make food, hardware ﹠ tools packing plastics goods, automotive upholstery, motorcycle decorative panel, inner container of icebox, light fixture etc.Its heater (can be described as baking oven) is to utilize ceramic heating piece on the casing (or pipe) that plastic sheet or sheet material are heated to make it softening.In heating process, heat slowly is delivered to inside from the surface of plastic sheet (plate) material, and the heat transmission speed is slower, causes the surface and the temperature inside temperature difference of plastic sheet (plate) material bigger, to plastic sheet (plate) material to add thermal effect not really desirable, influenced the quality of its thermoforming.And ceramic heating piece (or pipe) need be in febrile state for a long time during the work of this thermoforming machine, and the energy has been caused waste.
Three, summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, and the heater that a kind of energy transmission speed is fast, heat effective plastic sheet (plate) sheet (panel) hot-forming is provided.
Purpose of the present invention realizes by following technical solution: the heater of a kind of plastic sheet (plate) sheet (panel) hot-forming, comprise casing, the bottom of described casing is made of reflector, under reflector, infrared radiator is housed, on reflector, corresponding infrared radiator and end positions place thereof respectively be provided with body louvre, tube head louvre; The top of described casing is equipped with radiator fan and is provided with the ventilating opening corresponding with radiator fan, and the wind that radiator fan blows out enters casing by this ventilating opening.
After adopting structure of the present invention, the energy that infrared radiator sends can pass to plastic sheet (plate) material rapidly through self direct projection and reflection of reflecting, and is penetrated into the bottom from the surface of plastic sheet (plate) material fast, all sidedly and makes its Fast Heating and soften.Open when this infrared radiator uses, do not use and to close.Therefore, energy transmission speed of the present invention is fast, heating is effective, can increase substantially heat efficiency, and electricity saving and energy saving, has significant technological progress.
Four, description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of the heater of plastic sheet of the present invention (plate) sheet (panel) hot-forming.
Fig. 2 is the upward view (not comprising infrared radiator) of Fig. 1.
Fig. 3 is the left view of Fig. 2.
Fig. 4 is the partial enlarged drawing of the mark I among Fig. 2.
Five, the specific embodiment
Referring to figs. 1 through Fig. 4 as can be known, the heater of plastic sheet of the present invention (plate) sheet (panel) hot-forming, comprise casing 1, the bottom of described casing 1 is made of reflector 2, at reflector 2 times (by anchor clamps 10) infrared radiator 3 is housed, on reflector, corresponding infrared radiator and end positions place thereof respectively be provided with body louvre 4, tube head louvre 5; The top of described casing 1 is equipped with radiator fan 6 and is provided with the ventilating opening 7 corresponding with radiator fan 6, and the wind that radiator fan blows out enters casing by this ventilating opening.
Wherein the material of reflector 2 can adopt stainless steel, and reflecting effect is good; Infrared radiator 3 can be installed several as required, the radiator pressure regulation temperature control equipment of it and this thermoforming machine links, control the energy size of sending by regulating its voltage, it can adopt the twin tubular type infrared radiator of medium wave (or carbon medium wave), and (energy that sends is higher, transmission effect is good, and moderate), (energy that sends is very high also can to adopt shortwave single tube (or twin pipe) formula infrared radiator, transmission effect is splendid, but price is higher); The periphery of casing 1 is provided with heat-insulation layer 11 (can adopt asbestos material), as shown in Figure 1.The body louvre corresponding with the body of infrared radiator is some groups (corresponding with the number of infrared radiator), every group is made of several apertures, the tube head louvre corresponding with the two ends of infrared radiator also is some groups, and every group is made of two apertures, as shown in Figure 4.On the reflector 2, locate to be provided with anchor clamps hole 8 between body louvre 4 and the tube head louvre 5, be used for placing the anchor clamps 10 that infrared radiator is contained on the reflector and use; On reflector 2, the outside of tube head louvre 5 can be provided with wire hole 9, be used for placing relevant electric wire and use, as shown in Figure 4.
Operation principle of the present invention is: plastic sheet (plate) material after the feeding operation of above-mentioned thermoforming machine, be placed on this heater under.Open infrared radiator and send energy, this energy passes to plastic sheet (plate) material rapidly through self direct projection and reflection of reflecting, and reach design temperature in second at 1--2, be penetrated into the bottom from the surface of plastic sheet (plate) material fast, all sidedly and make its Fast Heating and soften.Simultaneously, start radiator fan, the wind that radiator fan blows out enters into casing steadily, equably behind ventilating opening, and by apertures such as body louvre, tube head louvres infrared radiator is played the heat radiation protection effect.Then close infrared radiator after heating process is finished, wait for that new plastic sheet (plate) material enters unlatching again.
