The specific embodiment
Referring to Fig. 1-Fig. 3, a kind of safety-type dotter comprises frame 2, fixed mould 22, Impact mould 21, mould transmission mechanism 1, clutch, pedal switch 12 and safety device.Its safety device mainly is a U-shaped protective plate 20, and is divided into up and down two parts, and is connected as a single entity by screw, and the two ends hinge on top is connected on the frame 2 of Impact mould 21 tops, and with horizontal struts 24 vertical being connected as a single entity.It is the end that hook solid hangs over a waling stripe 8 that one vertical links, 10 upper ends are arranged, insert in the jack of pedal switch 12 pedal the inners the lower end of vertical links 10, but be with a up-down adjustment and the external diameter spacing collar 11 greater than pedal switch 12 jacks on the vertical links 10.Regulate the high and low position of spacing collar 11, can change the amplitude of fluctuation of U-shaped protective plate 20.The middle part of waling stripe 8 is connected with frame 2 hinges, in frame 2 upper hinge junctions one torsion spring 9 that waling stripe 8 free ends are upwards lifted is housed, the joint pin 23 on waling stripe 8 free ends rides on the horizontal struts 24 or inserts in the elongated slot that is provided with on the horizontal struts 24.Depress pedal switch 12, U-shaped protective plate 20 is swung forward, unclamps and steps on formula switch 12, and U-shaped protective plate 20 is swung backward.On the horizontal struts 24 of U-shaped protective plate 20 upper ends connection a horizontal pressure foot 18 is housed, connects an extension spring 17 on it, the other end of extension spring 17 is fixed on the frame 2, and U-shaped protective plate 20 is swung backward.Pilot hole and the vertical depression bar 16 that guide ring 15 can move down on frame of passing 2 are arranged, withstand on it on cam 25 bottom surfaces on mould transmission mechanism rotating shaft 6 one ends, the lower end withstands on the horizontal pressure foot 18 of horizontal struts 24, and U-shaped protective plate 20 is swung forward.
Described pedal switch 20 is middle and frame 2 hinged pedals, and the pedal outer end is manually to hold, and inner push rod 7 lower ends with a upper end promotion clutch are connected.Described clutch comprises the axle sleeve 4 that is contained in the mould transmission mechanism rotating shaft 6, the latch 3 that one spring 26 promotes along horizontal movement is housed on the axle sleeve 4, latch slot 14 is set on the driving pulley 5, wedge-like clutch 12 lower ends are connected with frame 2 hinges, one side is provided with horizontal pin, have an end of a clutch extension spring 27 to be connected in wedge-like clutch 13 middle parts, the other end is connected with frame 2; Push rod 7 upper ends that are connected with an end of pedal switch 12 withstand on the horizontal pin of wedge-like clutch 13.
During use, keep rotating by driven by motor belt pulley 5 always, earlier clasp is put in the following fixed mould 22, put the clothing that needs to beat button well, with pedal switch 12 under the hand, pedal switch 12 makes horizontal struts 24 drive U-shaped protective plates 20 and swings certain angle forward by vertical links 10 and waling stripe 8 free end to the horizontal struts 24 that presses down U-shaped protective plate 20, and the hand that can block the operator can not enter the spatial dimension that Impact mould 21 moves downward.Simultaneously, promote the horizontal pin of wedge-like clutch 13 by push rod 7, wedge-like clutch 13 is moved down, latch 3 front ends in the mould transmission mechanism rotating shaft axle sleeve 4 are under spring 26 effects, insert in the latch slot 14 on the driving pulley 5, belt pulley 5 just can drive 1 work of mould transmission mechanism like this, above the less planar section of cam 25 radiuses on mould transmission mechanism rotating shaft 6 one ends goes to, the arc surface that radius is bigger goes to the bottom to pressing down vertical depression bar 16 upper ends, vertical depression bar 16 lower ends withstand on the horizontal pressure foot 18 of horizontal struts 24, the angle that U-shaped protective plate 20 is swung forward remains unchanged, move downward until Impact mould 21, beat button.
At this moment, pedal switch 12 has unclamped, and wedge-like clutch 13 upwards resets under the effect of clutch extension spring 27, the pointed part in the upper end of wedge-like clutch 13 pushes latch 3 in the mould transmission mechanism rotating shaft axle sleeve 4, makes mould transmission mechanism 1 no longer along with belt pulley 5 rotates.U-shaped protective plate 20 also under its extension spring 17 effects, is swung certain angle backward and is resetted, and reserves the space of placing clasp and clothing with hand.At this moment, below the less planar section of cam 25 radiuses on mould transmission mechanism rotating shaft 6 one ends went to, vertical depression bar 16 was promoted to move up by the horizontal pressure foot 18 of horizontal struts 24, and vertical depression bar 16 upper ends just withstand on the less plane of cam 25 radiuses and reset.So far, finish and once play button work.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
