the specific embodiment:
Below in conjunction with accompanying drawing, the present invention is described in detail.
Referring to Fig. 1, connecting device of the present invention, for being connected cooling body and the rewinding mechanism of roller drum offset machine, comprises hold-down mechanism, paper cutting mechanism and paper splicing mechanism.Hold-down mechanism and paper splicing mechanism belong to rewinding mechanism, and paper splicing mechanism belongs to cooling body.
In conjunction with Fig. 2, rewinding mechanism comprises support 13, driven wheel rotating shaft 2, turning arm 10, left support abutment 8 and right support abutment 6.Driven wheel rotating shaft 2 is rotatably connected on support 13, and by being fixed on the driven wheel of both sides and the drive unit transmission of rewinding mechanism is connected.Left support abutment 8 and right support abutment 6 are located at respectively the left and right sides of driven wheel rotary main shaft 2.Turning arm 10 is three, be fixed on left support abutment 8 and right support abutment 6 respectively, and between adjacent, angle is 120 degree and is evenly distributed on driven wheel rotating shaft 2 around centered by driven wheel rotating shaft 2.Each turning arm 10 comprises two supports of being located at respectively driven wheel rotating shaft 2 both sides.On each turning arm 10, be equipped with a hold-down mechanism and a paper splicing mechanism.Wherein hold-down mechanism comprises clamping cylinder 9, hold-down roller 5 and compresses support 4.Clamping cylinder 9 is located on the support of corresponding turning arm 10.Compressing support 4 is connected with the cylinder rod of clamping cylinder 9 by hold-down roller 5.Paper splicing mechanism comprises the gentle expansion core axle 16 of little paper web 7.Little paper web 7 is placed on inflatable mandrel 16.Inflatable mandrel 16 two ends are arranged on respectively on two side stands of corresponding turning arm 10.
Referring to Fig. 2 and Fig. 3, paper cutting mechanism comprises splicing roller support 1, drives cut paper cylinder 3, rotating shaft 12, splicing roller 15 and hand papercutter 17.Rotating shaft 12 is rotatably connected between the left wallboard 14 and right wallboard 11 of cooling body, and by being fixed on the travelling gear of both sides and the drive unit transmission of cooling body is connected.Splicing roller 15 is connected with rotating shaft 12 by splicing roller support 1.Drive cut paper cylinder 3 to be located at the lower end of splicing roller support 1, hand papercutter 17 is connected with driving the cylinder rod of cut paper cylinder 3.
During initialization, the drive unit of rewinding mechanism (motor) rotates by driving gear drives rotating shaft 2 driven rotary arms 10, make one of them turning arm 10 and the angle of horizontal direction be 30 degree, the drive unit driven rotary axle 12 of cooling body rotates simultaneously, make little paper web on above-mentioned turning arm 10 7 and be located at splicing roller 15 on cooling body in tangent state, one end of paper is connected to little paper web 7 from splicing roller 15.
Complete after splicing, the drive unit of cooling body (electric rotating machine) is rotated counterclockwise certain angle by gear drive rotating shaft 12, and now splicing roller 15 moves to lower position; The drive unit of rewinding mechanism passes through driven wheel simultaneously, drive driven wheel rotating shaft 2 120 degree that turn clockwise, by completing little paper web after splicing, go to the position of below, the little paper web 7 of the now not splicing on another turning arm 10 arrives the position of former little paper web, in treating splicing state.18 rollings of paper on splicing roller 15, to the little paper web 7 of splicing, are carried out to paper rolling, referring to Fig. 5.
When rolling paper web arrives certain diameter, rotating shaft 12 dextrorotations go to initial position, tangent with the little paper web 7 for the treatment of splicing, now paper are joined again.Clamping cylinder 9 drives hold-down rollers 5 to compress paper to be cut (between little paper web in just having joined of this section of paper and the little paper web spooled) by compressing support 4, then, driving is in opening the cut paper cylinder 3 of opposite side with cut paper, the latter drives hand papercutter 17, paper is cut off, referring to Fig. 4, complete whole paper handshaking.Paper cutting is had no progeny, and can little paper web that spool paper be unloaded automatically by inflatable mandrel 16 to the little paper web more renewing simultaneously.
Complete after cut paper, the electric rotating machine of cooling body drives rotating shaft 12 to be rotated counterclockwise certain angle, and the driven by motor driven wheel rotating shaft 2 of rewinding mechanism 120 degree that turn clockwise, carry out the rolling of paper simultaneously.Repeat thus the handing-over of paper.
By connecting device of the present invention, can effectively realize the automatic handing-over of paper, thereby reach the serialization of whole production process.
