Abstract
The utility model discloses a heating device for heat molding machine of plastic sheet material, which comprises a box (1). The bottom of the box (1) is made by reflector panel (2). The reflector panel (2) is provided with an infrared radiator (3) underneath. The reflector panel is provided with a tube cooling hole (4) and a tube heat cooling hole (5) corresponding respectively to the infrared radiator and tow ends of the infrared radiator. The top of the box (1) is arranged with a cooling fan (6) and a ventilation port (7) corresponding to the fan (6). Air blown out of the cooling fan enters the box through a ventilation port. Energy generated by the infrared radiator is transmitted to a plastic sheet material after self collineation and reflection of the reflector panel. After the energy penetrates quickly and completely through the surface of the plastic sheet material, the material is heated and softened. The utility model has a fast speed in energy transmission and good effect in heating, improves the heating efficiency by a large margin and saves electricity and energy.
Description
One, technical field
The utility model relates to and a kind of plastic sheet or sheet material is carried out the hot-forming machine for plastic sheet of thermoforming (utilizing malleation, negative pressure or mold pressing principle), specifically relates to the heater that a kind of hot-forming machine for plastic sheet is used.
Two, background technology
Existing hot-forming machine for plastic sheet 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, and the heat transmission speed is slower, causes the surface of plastic sheet and the temperature inside temperature difference bigger, to plastic sheet 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, utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and the heater of the hot-forming machine for plastic sheet that a kind of energy transmission speed is fast, heating is effective is provided.
The purpose of this utility model realizes by following technical solution: a kind of heater of hot-forming machine for plastic sheet, 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 the utility model structure, the energy that infrared radiator sends can pass to plastic sheet rapidly through self direct projection and reflection of reflecting, and is penetrated into the bottom from the surface of plastic sheet fast, all sidedly and makes its Fast Heating and soften.Open when this infrared radiator uses, do not use and to close.Therefore, the utility model energy transmission speed is fast, heating is effective, can increase substantially heat efficiency, and electricity saving and energy saving, has significant technological progress.
Four, description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the structural representation of the heater of the utility model hot-forming machine for plastic sheet.
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 the utility model hot-forming machine for plastic sheet, 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 utility model is: plastic sheet 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 rapidly through self direct projection and reflection of reflecting, and reaches design temperature at 1--2 in second, is penetrated into the bottom from the surface of plastic sheet fast, all sidedly and makes 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 enters unlatching again.
