Abstract
The utility model discloses a sheet material thickness secondary adjustment device, and in particular relates to a heat compensation device positioned in a sheet material production line. The heat compensation device is positioned between a longitudinal stretching unit and a transverse stretching unit in the sheet material production line. By applying the sheet material thickness secondary adjustment device, the yield is improved by 3 percent; according to the current productivity of producing 50 tonnages of products every day, 1.5 tonnages of qualified products can be increased, and the economical benefit can be increased by 15,000 RMB or so every day, and therefore, the application prospect is very wide.
Description
Technical field
The utility model relates to a kind of sheet thickness adjusting device, specifically, relates to a kind of sheet thickness secondary adjusting device.
Background technology
Existing polystyrene sheet material is when THICKNESS CONTROL, adopt thickness measuring system to detect, the data result that detects is transferred to the die head control system, the aperture of carrying out die lip by the die head control system is regulated again, realize the control of thickness, this is the most basic control method.In use experience for many years, often run into the adjusting of various special factor affecting thickness.All have influence on the adjusting of thickness as the variation of the water yield or the difference of water temperature etc. in certain regional variation of ambient temperature and the somewhere chill roll in the production line.Thickness measuring testing result feedback distortion phenomenon appears when serious.
The utility model content
At the problems referred to above that prior art exists, the purpose of this utility model provides a kind of sheet thickness adjusting device, and the secondary thickness that is particularly useful for the biaxially oriented polystyrene sheet material is regulated.
For realizing above-mentioned utility model purpose, the technical solution adopted in the utility model is as follows:
A kind of sheet thickness secondary adjusting device is specially a heat compensation device that is arranged in sheet production line.
Preferably, described sheet material is the biaxially oriented polystyrene sheet material.
Preferably, between the longitudinal stretching unit and cross directional stretch unit of described heat compensation device in described sheet production line.
More preferably, be provided with at least one group of heater in the described heat compensation device.
More preferably, every group of described heater moves according to the width of sheet material behind longitudinal stretching by a moving assembly.
More preferably, the moving assembly of described heater comprises heater bracing frame, slide block, line slideway and movable stand, described heater bracing frame is positioned at described heater base, and described slide block and line slideway are slidingly connected, and described movable stand is used for mobile described heat compensation device.
More preferably, the heating-up temperature of described heater is according to each the regional thickness adjustment in the sheet material.
Compared with prior art, the utility model provides a kind of sheet thickness secondary adjusting device, be specially a heat compensation device, the position of its every group of heater can be moved according to the width behind the longitudinal stretching, and according to the different heater of the thickness of a certain part in the sheet material behind the longitudinal stretching, and heating-up temperature can arrange adjusting, thereby makes the sheet material behind the longitudinal stretching obtain entering the uniform cross directional stretch of energy in the cross directional stretch baking oven after the amount of localized heat compensation, realizes the even regulation of thickness.After the sheet thickness secondary adjusting device that application the utility model provides, yield rate has improved 3%, calculates by existing production capacity 50 tons of products every day, can increase by 1.5 tons certified products, increase about 1.5 ten thousand yuan of economic benefits every day, so its application prospect is very wide.
Description of drawings
The structural representation of the sheet thickness secondary adjusting device that Fig. 1 provides for the utility model;
Among the figure: 1, heater, 2, the heater bracing frame, 3, slide block, 4, line slideway, 5, movable stand.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing to the utility model do further in detail, intactly explanation.
The structural representation of the sheet thickness secondary adjusting device that Fig. 1 provides for the utility model, as shown in Figure 1, described sheet thickness secondary adjusting device, be one to be arranged in the heat compensation device of sheet production line, between the longitudinal stretching unit and cross directional stretch unit of described heat compensation device in described sheet production line; Be provided with many group heaters in the described heat compensation device; Every group of described heater moves according to the width of sheet material behind longitudinal stretching by a moving assembly; The moving assembly of described heater comprises heater bracing frame, slide block, line slideway and movable stand, and described heater bracing frame is positioned at described heater base, and described slide block and line slideway are slidingly connected, and described movable stand is used for mobile described heat compensation device.The heating-up temperature of described heater is according to each the regional thickness adjustment in the sheet material.
Polystyrene sheet material drawing process carries out in two steps, carries out longitudinal stretching earlier, then carries out cross directional stretch.Behind longitudinal stretching and before the cross directional stretch in this section transition period, because sheet material is to expose in air, heat post bake by this sheet thickness secondary adjusting device as accurately locating, thereby make the sheet material behind the longitudinal stretching obtain entering the uniform cross directional stretch of energy in the cross directional stretch baking oven after the amount of localized heat compensation, realize the even regulation of thickness.
Be necessary at last in this explanation to be: above embodiment only is used for the technical solution of the utility model is done explanation in further detail; can not be interpreted as the restriction to the utility model protection domain, some nonessential improvement and adjustment that those skilled in the art makes according to foregoing of the present utility model all belong to protection domain of the present utility model.
