Description

Conveying transition device and cutting equipment after tread cutting

Technical Field

The utility model relates to the field of tire manufacturing, in particular to a tread conveying transition device after cutting and cutting equipment.

Background

The tread is an essential component of the tire. The tread is a flat long strip-shaped structure in the production and processing process, and in order to facilitate the processing and shaping of subsequent tires, the tread needs to be cut into individual small treads by a cutting device.

The output side of backup pad 40 is provided with cylinder 70, and the tread that cuts out is carried outwards through cylinder 70, is provided with transition board 80 between cylinder 70 and the backup pad 40, and transition board 80 fixed mounting is on frame 10, and the upper surface of transition board 80 is high parallel and level with the roller 70 upper end for the tread can be smooth and easy through transition board 80 entering cylinder 70 in, in addition, is provided with pressure strip 50 above transition board 80 in the output side of backup pad 40, and pressure strip 50 compresses tightly the tread on transition board 80 when cutting to ensure that the tread can not remove.

The spacing between the support plate 40 and the drum 70 can be reduced by providing the transition plate 80, thereby preventing the subsequent tread from entering the gap between the drum 70 and the support plate 40 during movement. As shown in fig. 3, the side of the transition plate 80 facing the drum 70 is provided with a slope 82, and by providing the slope 82, the gap between the transition plate 80 and the drum 70 becomes smaller, i.e., the transition plate 80 and the drum 70 are disposed immediately adjacent.

The conveying component 20 may be a conveying belt, and the width of the conveying belt needs to be greater than or equal to the width of the tread, because the tread can be spread on the conveying component 20 in a fully-unfolded manner, the conveying of the tread is convenient, more importantly, the subsequent cutting quality can be ensured, and the problems of poor shape of the incision and the like caused by incomplete unfolding of the tread are avoided.

When the tread cutting device is used, the tread (not shown) is laid on the conveying component 20 and driven by the conveying component 20 to move to the position where the roller 70 is located until the conveying component 20 conveys the tread by a preset length (the length is determined according to the specification of the tire), and at this time, the conveying component 20 stops moving; the compacting plates 50 move downwards to compact the tread, so that the tread is ensured not to be displaced; then the cutter 33 moves from one side of the tread to the other side to cut the tread; the cut small tread is driven by external equipment to move forward on the roller 70; finally, the cutter 33 is reset, and a cutting action is realized.

As shown in fig. 2, the cutting portion 331 at the left end of the cutter 33 is disposed above the supporting plate 40, and when the cutter 33 cuts the tread along the upper side of the supporting plate 40, that is, the position of the supporting plate 40 is the position of the tread cutting position.

As shown in fig. 2, the supporting plate 40 is in an elongated plate structure, and the length of the supporting plate 40 needs to be greater than or equal to the width of the tread, so that the tread can be tiled on the supporting plate 40, and the tread is fully unfolded, so that the cutting of the cutter 33 is facilitated. Further, in order to ensure that the lower surface of the tread is completely cut off, the upper surface of the support plate 40 is provided with a cutting groove recessed downward, the extending direction of the cutting groove is identical to the direction in which the tread is to be cut, in this embodiment, both the left and right ends of the cutting groove extend to the end portions of the support plate 40, so that openings for the cutting blade 33 to enter and exit are formed at both end portions of the support plate 40, so that the cutting blade can cut the lower surface of the tread in the process of moving from one side of the tread to the other side. The rest of the upper surface of the support plate 40 except the position where the cutting groove is located is used for supporting the tread during cutting, which is also called a support surface, and the shape of the support surface can adopt the shape that the inclined surface and the plane of Chinese patent (CN 216099185U) are connected with each other so as to facilitate the conveying of the tread.

In addition, the supporting plate 40 in the present embodiment is liftable, specifically referring to fig. 2 and 3, a through hole 81 penetrating up and down is provided on the transition plate 80, the supporting plate 40 is provided in the through hole 81, and a lifting assembly 41 is provided below the supporting plate 40, and the lifting assembly 41 controls the supporting plate 40 to lift in the through hole 81. When cutting, lifting assembly 41 drive backup pad 40 upwards removes for the upper surface of backup pad 40 is higher than the upper surface of transition board 80, and then tread is upwards promoted by backup pad 40, and then the tread is closer to the position that cut-off knife 33 is located, and the cut-off knife 33 of being convenient for cuts and makes the tread groove that cuts and form reduce, small-angle cuts promptly, and such advantage lies in: the contact area in the time of follow-up laminating roll-in can be increased, the possibility that splits after the tread laminating is reduced. When the tread is not cut, the lifting assembly drives the supporting plate 40 to descend, so that the upper surface of the supporting plate does not exceed the transition plate 80, the tread can smoothly pass through the transition plate 80 with smaller resistance, and at the moment, a height difference exists between the tread and the cutter, and the cutter is prevented from cutting the tread.

As shown in fig. 4, the elevation assembly 41 includes an elevation cylinder disposed longitudinally, a piston rod of which is fixedly coupled to a lower surface of the support plate 40, thereby driving the support plate 40 to perform an elevation motion. In addition, a guide assembly including a guide bar may be provided on the support plate 40 to ensure that the support plate moves along a predetermined trajectory when lifted and lowered, thereby preventing the support plate from being deflected.

As shown in fig. 2, the compacting plate 50 has a flat plate structure and a flat lower surface, so that the compacting plate 50 can be stably compacted on the tread when moving downwards to a compacting position, ensuring that the tread is stably fixed and preventing the tread from moving. And the length of the pressing plate 50 is preferably close to the width of the tread, so that the whole width direction of the tread can be pressed, and the situation that the whole position of the tread in the width direction is not deviated during cutting is ensured.
