The described button dynamics adjusting device of beating comprises a regulating part 6 and a movable holder 7 that cooperates with it, described movable holder 7 is arranged on above-mentioned spring 3 belows, this activity holder 7 has a sliding end 71 and positive stop end 72, upwards be provided with at least one projection 711 in 71 weeks of sliding end, in the present embodiment, be arranged with two projections 711, this projection 711 may be stuck in the described elongated slot 12 and along these elongated slot 12 displacements; This activity holder 7 is concaved with a spring base 73 vertically in sliding end 71 1 sides and is installed with the location for above-mentioned spring 3.Described positive stop end 72 radially is penetrated with a through hole 722, one needle roller axles 74 and is arranged in this through hole 722, and the length of this needle roller axle 74 is greater than through hole 722 length of activity holder 7, so that the two ends of needle roller axle 74 manifest outside this through hole 722.

The above-mentioned button dynamics adjusting device of beating comprises a regulating part 6, and its positive stop end 72 with above-mentioned movable holder 7 links to each other.Described regulating part 6 has a link 61 and an operating side 62, this regulating part 6 is concaved with a connecting hole 63 in link 61 1 sides along central shaft, positive stop end 72 for above-mentioned movable holder 7 is ccontaining, this regulating part 6 is provided with twice groove 64 at least in the end face of link 61, set for above-mentioned needle roller axle 74, the weight of each groove 64 differs, and is preferably smooth excessively (shown in Fig. 5,6) therebetween.Wherein, also can be at the two ends of needle roller axle 74 sheathed needle bearing 741 respectively, reduce the friction of itself and regulating part 6.

Above-mentioned buffer cover 5 also is provided with a shoulder hole 51 that connects along its central shaft, and near dsah-pot 1 one sides than the diameter of large through-hole 511 greater than away from the diameter of dsah-pot 1 than small through hole 512, the annulus wall of this buffer cover 5 is provided with and the corresponding through hole 52 of screwed hole 13 on the dsah-pot 1, and this buffer cover 5 is fixedly connected on the dsah-pot 1 by suitable fixtures such as screws 53.The operating side 62 of above-mentioned regulating part 6 passes above-mentioned shoulder hole 51 and outside being revealed in, and its link 61 be located in this buffer cover 5 than in the large through-hole 511 and blocks on this end wall than small through hole 512.In addition, also can between above-mentioned regulating part 6 and buffer cover 5, plane bearing 54 be set, to reduce the friction of regulating part 6.

Described die shoe 2 down is arranged in the shoulder hole 11 of this dsah-pot 1, and its stiff end 22 blocks are on the end wall than small through hole 112; Above-mentioned spring 3 is enclosed within the above-mentioned binding end 21 of die shoe 2 down, above-mentioned movable holder 7 is inserted in the elongated slot 12 of above-mentioned dsah-pot 1 by its projection 711, above-mentioned spring 3 one ends are resisted against down the stiff end 22 of die shoe 2, and the other end is by spring base 73 and contact is positioned above-mentioned movable holder 7; In the through hole 722 of above-mentioned needle roller axle 74 insertion activity holders 7, and in its two ends installation needle bearing 741, above-mentioned regulating part 6 is enclosed within on the positive stop end 72 of movable holder 7 by connecting hole 63, and needle roller axle 74 correspondences are established in the groove 64 of regulating part 6.Link 61 blocks and make the screwed hole 13 corresponding settings of its through hole 52 and dsah-pot 1 on the end wall than small through hole 512 of buffer cover 5.Screw 53 passes the through hole 52 of above-mentioned buffer cover 5 and is screwed into the screwed hole 13 of dsah-pot 1, so that above-mentioned buffer cover 5 is fixedlyed connected with dsah-pot 1; Above-mentioned die shoe 4 penetrates and is positioned in the shrinkage pool 23 of above-mentioned die shoe 2 down from the shoulder hole 11 of above-mentioned dsah-pot 1.By screw 14 buffer unit of the present invention is installed on dozen button machine, as shown in Figure 4.

Thicker or the number of plies needs to increase the button dynamics of beating more at most when cloth, this moment manually or the operating side 62 by the above-mentioned regulating part 6 of instrument (for example spanner) rotation spring 3 is compressed.Because the projection 711 of above-mentioned movable holder 7 is embedded in the elongated slot 312 of dsah-pot 1, promptly movable holder 7 can not be rotated, above-mentioned regulating part 6 rotates relative to movable holder 7, so that the darker groove 64 of needle roller axle 74 degree of depth from regulating part under the bias voltage of spring 3 in the movable holder 7 turns to the more shallow groove of the degree of depth 64, thereby promotion activity holder 7 outside motion compresses springs 3, and then increase the button dynamics of beating.

And when cloth thin slightly or number of plies attenuation more after a little while since beat the button dynamics be set at bigger, then because the existence of buffer unit does not then need to transfer once more machine to alleviate dozen button dynamics.And work as the fabric thickness attenuation more for a long time, cross senior general's cloth and punch for fear of beating the button dynamics, then need to reduce the button dynamics of beating, need to rotate regulating part 6 this moment, needle roller axle 74 is turned to the darker groove of the degree of depth from the more shallow groove of the degree of depth under the bias voltage of spring 3, spring 3 length are increased, thereby reduced to beat the button dynamics.

When buffer unit of the present invention is used, can two kinds of dynamics be set: 1500 newton and 3800 newton on buffer unit according to playing the needs of button dynamics at present.Wherein dark groove 64 is corresponding with above-mentioned regulating part 6 for 1500 newton's dynamics, is fit to beat lightweight product this moment; 3800 newton's dynamics and above-mentioned regulating part 6 are wherein one corresponding than shallow grooves 64, are fit to beat Heavy Product this moment.Wherein, the position correspondence of each groove 64 can be embodied on the angle of relative buffer cover 5 rotations in operating side 62 of regulating part 6, for example be 50 degree.The dynamics that is the buffer unit start position is 1500 newton, and the dynamics to anticlockwise regulating part 62 about 50 degree positions is 3800 newton, if need convert 1500 newton to again, then gets final product to right rotation regulating part 62 about 50 degree positions.Same those skilled in the art can understand, also the mode of above-mentioned angle position by mark can be arranged on the buffer cover 5.Dynamics measurement through accurate instrument is set, not only accurately but also quick, corresponding dynamics acts on the corresponding product, can guarantee to get qualified product when the conversion dynamics.

In sum, buffer unit of the present invention can be guaranteed the safe handling of product, can alleviate operator's labour intensity again, and the accent machine settles at one go; And the present invention is simple to operate, and general operating personnel will operate through simple training, needn't use senior technical operation, thereby improve its production efficiency, provide cost savings simultaneously.
