The specific embodiment:
Below in conjunction with accompanying drawing the utility model is elaborated.
Referring to Fig. 1, the utility model connecting device is used to be connected the cooling body and the rewinding mechanism of roller drum offset machine, comprises hold-down mechanism, cut paper 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 S. A. 2, pivot arm 10, left support abutment 8 and right support abutment 6.Driven wheel S. A. 2 is rotatably connected on the support 13, and links to each other with the actuating device transmission of rewinding mechanism through the driven wheel that is fixed on both sides.Left support abutment 8 and right support abutment 6 are located at the left and right sides of driven wheel live spindle 2 respectively.Pivot arm 10 is three, is that center fixation is located on left support abutment 8 and the right support abutment 6 with driven wheel S. A. 2 respectively, and between adjacent angle be 120 degree be evenly distributed on driven wheel S. A. 2 around.Each pivot arm 10 comprises two supports of being located at driven wheel S. A. 2 both sides respectively.Be equipped with a hold-down mechanism and a paper splicing mechanism on each pivot arm 10.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 cooresponding pivot arm 10.Compressing support 4 links to each other with the cylinder rod of clamping cylinder 9 through hold-down roller 5.Paper splicing mechanism comprises little paper web 7 and inflatable mandrel 16.Little paper web 7 is placed on the inflatable mandrel 16.Inflatable mandrel 16 two ends are installed in respectively on two side stands of cooresponding pivot arm 10.
Referring to Fig. 2 and Fig. 3, cut paper mechanism comprises splicing roller support 1, drives cut paper cylinder 3, S. A. 12, splicing roller 15 and hand papercutter 17.S. A. 12 is rotatably connected between the left wallboard 14 and right wallboard 11 of cooling body, and links to each other with the actuating device transmission of cooling body through the transmission gear that is fixed on both sides.Splicing roller 15 links to each other with S. A. 12 through splicing roller support 1.Drive cut paper cylinder 3 and be located at the lower end of splicing roller support 1, hand papercutter 17 links to each other with the cylinder rod that drives cut paper cylinder 3.
During initialization; The actuating device of rewinding mechanism (motor) rotates through driving gear drives S. A. 2 driven rotary arms 10; Make one of them pivot arm 10 and the angle of horizontal direction be 30 degree; Simultaneously the drive device drives S. A. 12 of cooling body rotates, and makes the little paper web 7 on the above-mentioned pivot arm 10 be in tangent state with the splicing roller of being located on the cooling body 15, and an end of paper is connected on the little paper web 7 from splicing roller 15.
After accomplishing splicing, the actuating device of cooling body (rotating machine) is through gear drive S. A. 12 left-hand revolution certain angles, and splicing this moment roller 15 moves to lower position; The actuating device of the mechanism of rewinding simultaneously passes through driven wheel; Drive driven wheel S. A. 2 clickwises 120 degree; Go to the position of below with accomplishing little paper web after the splicing, the little paper web 7 of the not splicing on this moment another pivot arm 10 arrives the position of former little paper web, is in the splicing state of treating.18 rollings of paper on the splicing roller 15 to the little paper web 7 of splicing, are carried out the paper rolling, referring to Fig. 5.
When the rolling paper web arrived certain diameter, S. A. 12 dextrorotations go to initial position, and were tangent with the little paper web 7 of treating splicing, and once more join to paper this moment.Clamping cylinder 9 compresses paper to be cut (this section paper is between little paper web that has just joined and the little paper web of having spooled) through compressing support 4 drive hold-down rollers 5; Then; Driving is in the cut paper cylinder 3 that the band cut paper is opened opposite side, and the latter drives hand papercutter 17, and paper is cut off; Referring to Fig. 4, accomplish whole paper handshaking.After paper cuts off, can unload the little paper web that more renews simultaneously automatically through the little paper web that inflatable mandrel 16 will be spooled paper.
After accomplishing cut paper, the certain angle of rotating machine driven in rotation axle 12 left-hand revolutions of cooling body, driven by motor driven wheel S. A. 2 clickwises 120 degree of the mechanism of rewinding simultaneously carry out the rolling of paper.Repeat the handing-over of paper thus.
Through the connecting device of the utility model, can effectively realize the automatic handing-over of paper, thereby reach the serialization of whole process of production.
