A kind of sheet material stretching thickness adjusting apparatus
[technical field]
The utility model relates to the sheet material stretching device, relates in particular to a kind of sheet material stretching thickness adjusting apparatus that the thickness of sheet material is regulated.
[background technology]
Two-way extension phenylethylene (being BOPS) sheet production flow process generally is: feeding system → extrusion system → vertical pull system → horizontal pull system → crane span structure → thickness measuring → corona → coating → oven dry → rolling, because the thickness of sheet material is directly connected to the credit rating of sheet material, need constantly to monitor the thickness of sheet material in process of production, according to traditional BOPS thickness technology controlling and process, all be at extrusion system, vertical pull system (MDO) temperature, links such as horizontal pull system (TDO) width is provided with are regulated, but these means still can not solve the problem that sheet thickness is evenly accurately controlled fully in actual mechanical process, also exist thickness measuring and governing loop that relative sluggish phenomenon is arranged as adjustment; Regulate also respective process complexity of die head bolt, control inaccurate; Also can't avoid occurring situation in uneven thickness or that the limit is thick and regulate casting roller.
[summary of the invention]
The utility model provides a kind of direct, directly perceived, accurate and effective control sheet thickness device according to the deficiencies in the prior art.
The utility model is that the technical scheme that addresses the above problem is: described sheet material stretching thickness adjusting apparatus is divided into cooling segment and heating part, its characteristics are, described device integral body adds and is located at MDO curtain coating outlet, described heating part is by support, line slideway, travelling carriage, the heat block support, heat block constitutes, line slideway is erected on the support, line slideway slide guide direction is vertical with the sheet material trend, travelling carriage is installed in the line slideway, can in guide rail, slide, described heat block support can be provided with 1-3 according to the fabric width and the needs of sheet material, described heat block support and travelling carriage are hinged, can be central point with the pin joint, realize 180 ° rotation; Heat block is installed on the heat block frame, and the heat block in described each heat block support is the 2-6 piece; And described cooling segment is made of movable pedestal, blower fan, motor, and motor is electrically connected with blower fan, and the blower fan opening upwards, and is close below sheet material.
Described heat block support can be one or more, and 2-6 piece heat block is installed in each heat block support, and described heat block is ceramic infrared heating watt.
Described line slideway has guide runner, and the slide guide direction of guide runner is vertical with the sheet material trend;
Described travelling carriage is provided with sliding part, and sliding part is installed in the groove, and described sliding part is slide block or pulley;
Described movable base bottom is equipped with pulley.
The beneficial effects of the utility model: more perfect sheet thickness regulating system on single MDO and TDO mode basis, detect sheet material by thickness detection apparatus, grasp instant sheet thickness data, heating part can move towards direction at sheet material and vertically move and 180 ° of rotations of horizontal direction, can give sheet material any one corresponding slub heating, cooling segment moves flexibly, can give the cooling of sheet material weakness rapidly.The utility model is intuitively simple, and the staff is easy to operate and control, and effect is obvious, significantly reduces product disqualification rate and percent defective.

[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
With reference to accompanying drawing, sheet material stretching thickness adjusting apparatus among the embodiment is divided into cooling segment 2 and heating part 1, its characteristics are, described device integral body adds and is located at MDO curtain coating outlet, described heating part 1 is by support 1.1, line slideway 1.2, travelling carriage 1.3, heat block support 1.4, heat block 1.5 constitutes, line slideway 1.2 is erected on the support 1.1, line slideway 1.2 slide guide directions are vertical with sheet material 3 trends, travelling carriage 1.3 is installed in the line slideway 1.2, can in line slideway 1.2, slide, described heat block support 1.4 can be provided with 1-3 according to the fabric width and the needs of sheet material 3, demonstration in the present embodiment is provided with 2, heat block support 1.4 is hinged with travelling carriage 1.3, can be central point with the pin joint, realizes 180 ° rotation; Heat block 1.5 is installed on the heat block support 1.4, and the heat block 1.5 in described each heated holder 1.4 is 4.
Described heat block support 1.4 can be one or more, and 2-6 piece heat blocks 1.5 are installed in each heat block support 1.4, and described heat block 1.5 is ceramic infrared heating watt.
Described line slideway 1.2 has guide runner 1.21, and the slide guide direction of guide runner 1.21 is vertical with the trend of sheet material 3, and described travelling carriage 1.3 is provided with sliding part, and described sliding part is installed in the guide runner 1.21, and in the present embodiment, described sliding part is a slide block 1.31.
In practical operation, there is thickness detection apparatus to detect the thickness of the sheet material 3 that MDO curtain coating mouth 1 comes out immediately, the thickness that can accurately know sheet material 3 which position exceeds standard, this moment is along the mobile travelling carriage 1.3 of line slideway 1.2, drive moving of heat block support 1.4, rotation heat block support 1.4 allows heat block 1.5 aim at sheet material 3 desires heating position.Set the heat block temperature as required, regulate the control temperature at any time, satisfy technological requirement.
And described cooling end 2 minutes is made of movable base 2.1, blower fan 2.2, motor 2.3, and motor 2.3 is electrically connected with blower fan 2.2, blower fan opening 2.4 upwards, near below sheet material 3.Described movable base bottom is equipped with pulley 2.5.
Cooling down operation is similar to heating process, and by the movable base 2.1 of mobile blower fan 2.2, the location needs the cooling position, control sheet material 3 thickness.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
