Abstract
The utility model relates to a plastic sheet material rim charge cutting apparatus, comprising a frame, a knife rest, a guide rail, a lower rotor and a disc cutting knife; two ends of the lower rotor are respectively in connection with the frame through bearings; two ends of the guide rail are in connection with the frame and are located above the lower rotor; the disc cutting knife is located between the lower rotor and the guide rail and is in connection with the guide rail through the knife rest; the lower rotor is axially provided with a plurality of position-restricted discs in connection with the lower rotor; a cylinder is provided in the knife rest; a piston rod end of the cylinder is vertically downward and the end portion is provided with a radial shaft aperture; the disc cutting knife is in connection with the radial shaft aperture through a central shaft which is in connection with the disc cutting knife through a bearing; the central shaft between the radial shaft aperture and the disc cutting knife is sleeved with a spring.
Description
Technical field
The utility model relates to a kind of plastic sheet rim charge Scissoring device.
Background technology
Sheet extruder is through the die head extrusion sheet, and the sheet material both sides of extruding tend to occur phenomenons such as waste material is piled up, crooked wrinkling and flange, therefore before the rolling sheet material, need through the unnecessary rim charge in trimming device excision sheet material both sides.
Traditional trimming device, wing plate adopt blade type cutting knife excision rim charge, and its operation principle is: when needs excision rim charge, at first cutting knife is pressed and is worn sheet material, and cutter location is fixed then; Sheet material moves under the traction table that is provided with wrap-up front traction only, is cut by cutting knife during through cutting knife, and the unnecessary rim charge in its both sides is excised.But along with the development of extrusion sheet industry, the sheet forming linear velocity is more and more faster, and sheet thickness is also increasing.Therefore above-mentioned traditional trimming device tends to occur blade cutter relieving phenomenon when the cutting sheet material, causes the same phenomenons such as burr, bending and flange that occur of sheet material behind the excision rim charge.
Summary of the invention
The purpose of the utility model is exactly the weak point in the background technology, and a kind of plastic sheet rim charge Scissoring device is provided.
For achieving the above object, the utility model adopts following technical scheme: plastic sheet rim charge Scissoring device comprises frame, knife rest, guide rail, following rotor and disc cutter; Following rotor two ends are connected with frame through bearing respectively; The guide rail two ends are connected with frame and are positioned at rotor top down, and disc cutter is between following rotor and guide rail, and said disc cutter is connected with guide rail through knife rest; Said rotor down is axially arranged with the position-arresting disk that some and following rotor is connected; Be provided with cylinder in the knife rest, the tailpiece of the piston rod of cylinder vertically downward and its end be provided with radially axis hole, disc cutter is connected with axis hole radially through central shaft; Central shaft is connected with disc cutter through bearing, radially is arranged with spring on the central shaft between axis hole and the disc cutter.
For a kind of optimization of the utility model, said guide rail laterally is provided with scale.
For a kind of optimization of the utility model, said central shaft stretches out the radial axle nose end and is connected with snap close.
The utility model is compared with background technology, have rational in infrastructure, when excision sheet material rim charge; By cylinder disc cutter is moved down to following rotor outer rim, knife rest is moved along guide rail disc cutter and position-arresting disk are connected outside axially, and the central shaft of disc cutter is stretched out radially outside the axis hole; Spring shrinks, this moment the autobiography through position-arresting disk and disc cutter to rolling motion, thereby cut off machine edge material; Because the effect of spring makes disc cutter paste position-arresting disk all the time and rotates, and the cutter relieving phenomenon can not occur; The sheet cutting place is smooth, wrinkle resistant, can effectively avoid sheet material phenomenons such as burr, bending and flange to occur.

The specific embodiment
Embodiment 1: with reference to Fig. 1 ~ 3.Plastic sheet rim charge Scissoring device; Comprise frame 1, knife rest 4, guide rail 2, rotor 3 and disc cutter 6 down, following rotor 3 two ends are connected with frame 1 through bearing respectively, and guide rail 2 two ends are connected with frame 1 and are positioned at following rotor 3 tops; Disc cutter 6 is down between rotor 3 and the guide rail 2; And said disc cutter 6 is connected with guide rail 2 through knife rest 4, and said rotor 3 down is axially arranged with the position-arresting disk 7 that some and following rotor 3 is connected, and is provided with cylinder 9 in the knife rest 4; The tailpiece of the piston rod 9a of cylinder 9 vertically downward and its end be provided with radially axis hole 9a1; Disc cutter 6 is connected with axis hole 9a1 radially through central shaft 5, and central shaft 5 passes through bearing 8 and is connected with disc cutter 6, radially is arranged with spring 11 on the central shaft 5 between axis hole 9a1 and the disc cutter 6.Said guide rail 2 laterally is provided with scale 2a., said central shaft 5 stretches out radially axis hole 9a1 end and is connected with snap close 10.
What need understand is: though present embodiment is to the detailed explanation of contrasting of the utility model patent; But these explanations; It is simple declaration to the utility model; Rather than, anyly do not exceed innovation and creation in the utility model connotation to the restriction of the utility model, all fall in the protection domain of the utility model.
Claims (3)
