Abstract
The plastic sheet heating apparatus includes two, including one upper and one lower, heating boxes, and one horizontal plastic sheet conveying track between these two heating boxes. Of these two heating boxes, one has longitudinal strip heating elements arranged in parallel and separated into several groups connected separately to heating power controlling elements; and the other has transverse strip heating elements. The plastic sheet heating apparatus can heat the plastic sheet homogeneously.
Description
Technical field
The invention belongs to a kind of matching component of device of plastic processing, be specifically related to a kind of heating equipment of plastic sheet material.
Background technology
The plastic sheet parison can be that various finished products such as plastic containers, plastic sheet are processed into and at first must be sent to heater heating in the finished product process through being thermally processed into, and makes it softening even half melt.Be provided with the strip heater element of some parallel placements in the existing heater, as infrared lamp.Travel direction was called vertically when the plastic sheet parison was sent into heater, then was called laterally perpendicular to direction longitudinally.Be heated the temperature in transverse center zone, back apparently higher than the temperature of two side areas for fear of plastic sheet, the strip heater element of existing heating equipment of plastic sheet material all is placed to vertically, and be divided into the heater circuit that several is independently regulated and control power, every road heater circuit is only controlled two heater elements up and down, transfer lowly more the closer to the power of the heater circuit of horizontal centre in use, so just can avoid the temperature of the horizontal zone line of plastic sheet apparently higher than both sides.In order more specifically to investigate the temperature height situation of plastic sheet at the back each point that is heated, can be from transversely plastic sheet being divided into several unit areas, each unit area correspondence is each strip heater element up and down.Ensemble average temperature between each unit area that existing heater can only be controlled is basic identical, but in each concrete inside, unit area, because each point is bigger with the center position difference of corresponding heater element, thereby the temperature between the each point still has bigger difference, the difference of the temperature that some is local also can badly influence the evenness of wall thickness and the exterior quality of manufactured goods, causes producing defect ware.
Summary of the invention
The objective of the invention is to provide a kind of heating equipment of plastic sheet material, and it can make plastic sheet less in the temperature contrast amplitude of being heated between each lateral cell intra-zone each point of back.
Its purpose can realize by following scheme: this heating equipment of plastic sheet material comprises two heating cabinets up and down, between two heating cabinets, be provided with plastic sheet horizontal transmission guide rail, all be provided with the some strip heater elements that are arranged in parallel in two heating cabinets, strip heater element in one of them heating cabinet is vertical placement, and the strip heater element in this heating cabinet is divided into some groups, every group of component that is connected with its heating power of control respectively, its main feature is that the strip heater element in another heating cabinet is horizontal placement.
The scheme preferably that realizes above-mentioned purpose is: laterally heating element heater of placing and the distance between the plastic sheet horizontal transmission guide rail are less than the distance of vertically placing between heating element heater and the plastic sheet horizontal transmission guide rail.
Realize that the better scheme of above-mentioned purpose is: the maximum general power of laterally placing heating element heater is greater than the maximum general power of vertically placing heating element heater.
The present invention has following effect:
When 1, using heater of the present invention, the main effect of laterally placing heater element is that plastic sheet is heated, and the main effect of vertically placing heater element is to reduce the central area that horizontal heating element heater causes and the temperature difference of both sides on the whole.As long as will transfer more for a short time the closer to the power of vertical heating element heater of lateral mid-point, and just can realize that the ensemble average temperature in each lateral cell zone will be basic identical.
2, the amplitude of the fluctuation of the temperature value between each concrete lateral cell intra-zone each point variation is less.This mainly contains the reason of two aspects: the first, and at each concrete lateral cell intra-zone, the main priming factors of temperature value generation difference is vertical heater between the each point, has only the heater element of a heating cabinet to be placed to vertically among the present invention; Second, at each lateral cell intra-zone, laterally heater element is more even to the power ratio of heated at various points, basic not fluctuation, and laterally the general power of heater element can play a leading role the temperature level that internal temperature difference amplitude is cut down each point on the plastic sheet greater than vertical heater element.

Fig. 3 is a B-B cross-sectional view among Fig. 1.
The specific embodiment
Fig. 1, Fig. 2, heating equipment of plastic sheet material shown in Figure 3 comprise 1, following heating cabinet 5, between two heating cabinets 1,5, be provided with plastic sheet horizontal transmission guide rail 2, all be provided with the some strip heater elements that are arranged in parallel in two heating cabinets 1, strip heater element 3 in the wherein top heating cabinet is vertical placement, and the strip heater element in this heating cabinet is divided into some groups, every group of component that is connected with its heating power of control respectively, below strip heater element 4 in heating cabinet be horizontal placement.Laterally heating element heater of placing 4 and the distance between the plastic sheet horizontal transmission guide rail 2 are less than the distance of vertically placing between heating element heater 3 and the plastic sheet horizontal transmission guide rail 2.All laterally place the maximum general power of heating element heater 4 greater than the maximum general power of vertically placing heating element heater 3.
Claims (3)
1, a kind of heating equipment of plastic sheet material, comprise two heating cabinets up and down, between two heating cabinets, be provided with plastic sheet horizontal transmission guide rail, all be provided with the some strip heater elements that are arranged in parallel in two heating cabinets, strip heater element in one of them heating cabinet is vertical placement, and the strip heater element in this heating cabinet is divided into some groups, every group of component that is connected with its heating power of control respectively, it is characterized in that the strip heater element in another heating cabinet is horizontal placement.
2, according to the heating equipment of plastic sheet material of claim 1, it is characterized in that: laterally heating element heater of placing and the distance between the plastic sheet horizontal transmission guide rail are less than the distance of vertically placing between heating element heater and the plastic sheet horizontal transmission guide rail.：
