Abstract
The utility model relates to a hot roller heater of a plastic packing machine, comprising a metal bracket and an electric heating element arranged on the back of the metal bracket, which is characterized in that the cross section of the metal bracket is approximately in the shape of a C; a PTC heating component is adopted by the electric heating element and is vertically embedded in a corresponding caulking groove on the side of the back of the metal bracket. The PTC heating component comprises a PTC element, a positive and negative electrode tablet with the PTC element in the middle and an insulating film covered the outside of the PTC element. Adopting the PTC heating element, the heating temperature is always invariably at the setting PTC working temperature (commonly 135 DEG C plus or minus 5DEG C), therefore, the utility model has the advantages of no need for extra temperature control device and even heating compared with the prior art.
Description
Technical field
The utility model relates to a kind of parts of hot-rolling formula plastic packaging machine, particularly a kind of hot-rolling heater that is used for plastic packaging machine.
Background technology
The principle of plastic packaging machine is involutory plastic sheet to be packaged to be carried and through the gap between a pair of hot-rolling, by hot-rolling to its heating and with its encapsulation one.The hot-rolling heater commonly used adopts heating wire as heating element heater, its temperature height, causes overheatedly easily, therefore must be equipped with attemperating unit, and its heat be delivered on the hot-rolling also even inadequately, thereby cause bad plastic packaging effect.
Summary of the invention
Technical problem to be solved in the utility model is the hot-rolling heater that a kind of novel plastic packaging machine is provided at above-mentioned prior art present situation, and its homogeneous heating and temperature to hot-rolling is constant relatively.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the hot-rolling heater that is used for plastic packaging machine includes a metallic support and is arranged on the electrical heating elements at its back side, it is characterized in that described metallic support cross section roughly is the C font, described electrical heating elements adopts the PTC heating component, and longitudinally is embedded in the corresponding caulking groove of the metallic support back side one side.
Described PTC heating component is by the PTC element and with its positive and negative electrode sheet that is clipped in the middle and be coated on outer dielectric film and constitute.
Compared with prior art, the utility model is owing to adopted the PTC heating element heater, and its heating-up temperature is constant all the time on the PTC operating temperature of setting (being generally 135 ℃ ± 5 ℃), therefore need not the optional equipment attemperating unit, and homogeneous heating.
Description of drawings
Fig. 1 is the cross-sectional structural representation of the utility model embodiment.
Fig. 2 is the I portion enlarged drawing of Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the hot-rolling heater that is used for plastic packaging machine roughly is C font shape 1 (can adopt aluminium alloy) as support by a cross section, partly wrap in hot-rolling to be heated 3 peripheries, its back side one side is provided with a caulking groove 11 longitudinally, be equipped with in it by PTC element 23 and with its positive and negative electrode sheet 22 that is clipped in the middle and be coated on the PTC heating component 2 that outer dielectric film 21 constitutes, referring to Fig. 2.4 is plastic sheet to be packaged among the figure.
Claims (2)
1, a kind of hot-rolling heater that is used for plastic packaging machine, include a metallic support and be arranged on the electrical heating elements at its back side, it is characterized in that described metallic support cross section roughly is the C font, described electrical heating elements adopts the PTC heating component, and longitudinally is embedded in the corresponding caulking groove of the metallic support back side one side.
2, the hot-rolling heater that is used for plastic packaging machine according to claim 1 is characterized in that described PTC heating component is by the PTC element and with its positive and negative electrode sheet that is clipped in the middle and be coated on outer dielectric film and constitute.
