The volume of 211b.Multiple first matrix 211a close-packed arrays, recessing groove 212 are located between two the second matrix 211b.At other
In alternative embodiment, the single piece of pedestal 21 or an annular, the single piece can be opened up on outer peripheral surface it is several can
For the container 211c and a recessing groove 212 passed through for positioning mechanism 3 of 220 first end 220a of counter-wrapping rod pivot joint.
Such as Fig. 9 to Figure 10 is simultaneously combined shown in Fig. 6 to Fig. 8, and each positioning mechanism 3 includes the fixation for being fixed on fixing seat 20
The company of block 30, the output end 310 of the driving unit 31 being fixed on fixed block 30 and connection driving unit 31 and fixed block 30
Bar assembly 32.Specifically, fixed block 30 includes body part 301 and prolongs from 301 one end of body part towards what recessing groove 212 extended
Extending portion 302, body part 301 can be fixed in fixing seat 20 by screw, and extension 302 passes through recessing groove 212.Further,
Extension 302 is equipped with spaced two pivoting points, respectively the first pivoting point A and the second pivoting point B, link assembly 32
Fixed block 30 is pivotally connected to by two pivoting points.In the present embodiment, driving unit 31 be cylinder, driving unit 31 it is defeated
Outlet 310 is telescopic rod, and the seat of cylinder is fixed on body part 301, and telescopic rod 310 is parallel to main shaft 1 and connects link assembly
32.When telescopic rod 310 is shunk, link assembly 32 is in initial contraction state, and link assembly 32 will not compress tyre element 4
Head end.When telescopic rod 310 stretches out, link assembly 32 is in extended state, can compress the head end of tyre element 4.
As shown in FIG. 9 and 10, link assembly 32 includes the first swing rod 320 for being articulated in the first pivoting point A, is articulated in the
The second swing rod 321 of two pivoting point B and the pressing plate 322 for connecting the first swing rod 320 and the second swing rod 321.Driving unit 31 is also
Equipped with the connector 311 being slidably arranged on the second swing rod 321.Wherein, connector 311 connects the telescopic rod 310 of cylinder.?
In other alternative embodiments, connector 311 can be wholely set with telescopic rod 310.Pressing plate 322 includes the first swing rod of pivot joint
320, the interconnecting piece 322a of the second swing rod 321 and flat part 322b for pressing 4 head end of tyre element.Further, even
Socket part 322a is set there are two pivoting point, respectively third pivoting point C and the 4th pivoting point D.Wherein, the first swing rod 320 pivot joint the
Four pivoting point D, the second swing rod 321 is pivotally connected third pivoting point C, in this way, the first pivoting point A, the second pivoting point B, third pivoting point C
With the 4th pivoting point D-shaped at four vertex of a mobilizable quadrangle.Extension 302, the first swing rod of fixed block 30
320, the interconnecting piece 322a of the second swing rod 321 and pressing plate 322 is four sides of movable quadrangle, and between two adjacent sides
It is pivotally connected, meanwhile, the extension 302 of fixed block 30 is fixedly connected on pedestal 20.In addition, the extension of fixed block 30
302 one of side as movable quadrangle, it is irremovable since it belongs to a part of fixed block 30.Driving
Unit 31 is fixed on fixed block 30, and driving unit 32 is pivotally connected the second swing rod 321 (i.e. a side of quadrangle), to drive
Moving cell 31 can drive the second swing rod 321 to rotate around the second pivoting point B, the second swing rod 321 can with dynamic pressure plate 322 move axially,
Pressing plate 322 can drive the first swing rod 320 to rotate around the first pivoting point A.In short, driving unit 31 can drive it is above-mentioned mobilizable
Quadrangle changes shape in the same plane, so that link assembly 32 has aforementioned contraction state and extended state.
As shown in Fig. 9 to Figure 10, the first swing rod 320 is in V-shape, with two side (not labeled) that angle is obtuse angle.

The rotation of sliding and the second swing rod 321 of drive within the scope of certain angle in sliding slot 321a.It should be noted that sliding slot
The length of 321a can influence the rotation angle range of the second swing rod 321, i.e. sliding slot 321a is longer, and the second swing rod 321 chooses to install angle
Degree is bigger, and sliding slot 321a is shorter, and the rotation angle of the second swing rod 321 is smaller.The rotation angle of second swing rod 321 also influences pressing plate
322 shaft orientation moving range.
For tire assembly drum 100 of the invention before accessing tyre element 4, positioning mechanism 3 is in original state, works as tire
When the head end of component 4 accesses tire assembly drum 100, the 31 drive link component 32 of driving unit of positioning mechanism 3 is by original state
Switch to stitching state, then the head end of 32 pressable tyre element 4 of link assembly and holding, until tire assembly drum 100 rotates
One circle (completes coiled strip), and the 31 drive link component 32 of driving unit of positioning mechanism 3 is switched from first stitching state to original state,
Then link assembly 32 is in the state for not pressing tyre element 4, so that tire assembly drum 100 can carry out suturing tire portion in next step
The movement of part 4 head end and tail end.
The beneficial effects of the present invention are: the quadrilateral structure formed by cylinder drive link component 32, so that connection rod set
Part 32 has original state and stitching state, and link assembly 32 can press two and half drum devices 2 under stitching state
Outer surface, so that link assembly 32 can be by the head end of tyre element 4 when two and half drum device 2 of the head end of tyre element 4 access
It is maintained on two and half drum devices 2, thus when two and half drum devices 2 and two positioning mechanisms 3 rotate simultaneously, tyre element 4
Head end without departing from two and half drum devices 2, and then tire assembly drum 100 of the invention can smoothly complete coiled strip movement.
