Abstract

The utility model discloses a preheating device of in-mould ornamental plate material. The utility model comprises a temperature controller, an air heater, an air pump and an air pipeline, wherein the temperature controller is electrically connected with the air heater. An air outlet of the air pump is connected with an air inlet of the air heater. An air outlet of the air heater is connected with the air pipeline. The air pipeline is provided with an air outlet which is used for outputting hot air. The utility model uses an air heating method for the plate material, directly controls the temperature of the hot air, uses the air pipeline to isolate the hot air and basically generates no heat convection with the ambient air to lose heat. Thus, the utility model has little error and high control precision on controlling the temperature.

Description

Mold Decoration Sheet Pre-Heating Device
[technical field]
The utility model relates to a kind of pre-heated device of sheet material that is used for in-mold decoration (IML is In Mold Label) production technology.
[background technology]
At present, in-mold decoration (IML) technology is mainly used in the production fields such as control panel of mobile phone, automotive upholstery, household electrical appliance, control has strict requirement to the IML technology to sheet temperature, before the mould matched moulds, need sheet material that certain temperature is arranged, and temperature must have good stable, traditional embodiment utilizes the thermal resistance heating mould exactly, passes to sheet material by mould more then, perhaps heats for sheet material in advance by heat radiation.As shown in Figure 1, thermal resistance 2 heating mould dies 4, sheet material 1 is given in the heat conduction then, thermal resistance is heated to after the design temperature, because the departure of temperature control system itself, mould can be continued heating, and this just causes existing between temperature and the design temperature bigger error.And the electric radiation heating, as shown in Figure 2, be air by sheet material 1 top as conductor, the air of sheet material 1 top is heated after plate 3 heating the heat transferred sheet material, because the air of sheet material top and the convection current of ambient air occurrence of large-area, so the error that exists is bigger.
Because these two kinds heating and temperature-controlled process exist direct defective, often cause mold temperature and design temperature to have bigger error, and error and unstable, have therefore caused the defective products rate rising of product, have strengthened product cost.
[summary of the invention]
The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, and a kind of control accuracy height, Mold Decoration Sheet Pre-Heating Device that error is little are provided.
For achieving the above object, the utility model proposes a kind of Mold Decoration Sheet Pre-Heating Device, comprise temperature controller, air heater, air pump, air duct, described temperature controller is electrically connected with air heater, described air pump air outlet and described air heater air inlet join, described air heater air outlet and described air duct join, and described air channel is provided with an air outlet, are used for the heat outputting air.
Above-mentioned Mold Decoration Sheet Pre-Heating Device, described temperature controller comprises temperature collecting cell, this unit is arranged at the air outlet place of described air duct.Described air duct air outlet place is a bell mouth shape.
Owing to adopted above scheme, the utility model adopts the air heat mode to sheet material, and directly hot air temperature is controlled, adopt air pipe line that hot-air is isolated, make it substantially produce thermal convection current and loses heat with surrounding air, therefore little, control accuracy is high to temperature controlled error.
The temperature collecting cell of temperature controller is arranged at the air outlet place, accurately gathers the real work temperature to the sheet material preheating, can improve temperature controlled precision; The air outlet place is made as bell mouth shape, can increase the volume of air that covers in the sheet material place, and the thermal loss of hot-air can be ignored, to guarantee preheat temperature.
[description of drawings]
Fig. 1 is an electrical bar preheating schematic diagram of the prior art.
Fig. 2 is an electric radiation preheating schematic diagram of the prior art.
Fig. 3 is heater of the present utility model and preheating schematic diagram.
[specific embodiment]
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
As shown in Figure 3, the utility model mainly comprises: air pump 8, and it will make the air in the pipeline flow; Air flow line 9 guarantees that the air after the heating does not carry out the heat conduction with the external world; Air heater 7 heats air; Temperature controller 6 by the temperature that its temperature collecting cell 5 is gathered hot-air, is controlled air heater.As shown in Figure 3, in this process, sheet material is to be fixed on the die 4 by alignment pin in advance, then this device is forwarded to the die top, the air duct air outlet places the die top, utilizes hot-air that sheet material 1 is heated, after heating finished, this device was withdrawn, and begins moulding then.
Air pump 8 passes to air heater 7 with inhaled air by pipeline, after reaching design temperature after the air heater via is heated, blow to sheet material 1 through air pipe line 9, because air pipe line has been taked good provision for thermal insulation, air after the heating can not carry out the heat conduction with the external world, therefore the air themperature and the temperature difference between the air themperature after the air heater heating that blow on the sheet material are very little, within acceptable scope, so sheet material can reach the temperature of hope.The air duct opening is set to bell mouth shape, can increase the volume of air that covers in the sheet material place, and the thermal loss of hot-air can be ignored, to guarantee preheat temperature.Preheating scheme compared to prior art, the utility model temperature control error is little, control accuracy is high.
