Wirecord fabric low-angle cutting machine bag welt device
Technical field
The utility model relates to a kind of novel bag welt device of producing tire with wirecord fabric.
Background technology
Along with present domestic automobile sales volume ground increases, what bring is more and more stricter to the requirement of automobile tyre security energy and manufacturing technology level thereupon.The main make-up machine that adopts is realized carcass applying, moulding and anti-package in tire production.Wherein, on carcass drum, carry out before the sidewall composite members fits, need be to the two-sided enforcement bag welt operation (the less use of the tire of single face bound edge) of wirecord fabric.
As accompanying shown in Figure 1, existing tire is with the cutting machine bag welt device of wirecord fabric, its mainframe 11 and hanging between the frame 12 by being with 13 to connect synchronously, be with synchronously 13 by steering spindle 14, from mainframe 11 be delivered to hang form on the frame 12 Z-shaped.During operation, at first be that the A face on the mainframe 11 is carried out bound edge, after the part wirecord fabric is transferred on the suspension frame 12, again the B face carried out bound edge.In operating process, when the starting end of wirecord fabric entered the conveyer belt that hangs frame 12, production line integral body was in operating condition, and the operator need stand in the draw operations of carrying out the cord starting end on the mainframe 11, industrial accident very easily occurs.
As accompanying shown in Figure 2, the existing another kind of wirecord fabric bag welt device that adopts, its mainframe 21 be with 22 synchronously by steering spindle 23, be connected with conveyer belt 24 laterally.During operation, directly the A face curtains cloth on mainframe 21 carries out the bound edge processing; After treating that the A face all wraps welt and finishes, by conveyer belt 24 the B face of wirecord fabric is delivered to its bottom again, then the operator carries out bound edge with half crouch.There is no danger though the workman is positioned at conveyer belt 24 belows, wrapping process is had relatively high expectations, so labour intensity is bigger.
The two-sided bag welt quality of above-mentioned wirecord fabric directly has influence on the workmanship of sidewall moulding and final decision tire and safe in utilization, and the bag welt processing technology that therefore improves wirecord fabric is the technical task that must solve.
The utility model content
The purpose of this utility model is to solve the shortcoming and defect that above-mentioned existing bag welt device exists, provide and to realize 180 ° of upsets of cord, and carry out the cutting machine bag welt device of two-sided bag welt at grade, thereby under the prerequisite that guarantees the wrapping process quality, make the operator can operate, can't occur any dangerous hidden danger with normal stance.
Described wirecord fabric low-angle cutting machine bag welt device, it mainly has:
Move towards the identical frame of a pair of structure of arrangement along whole machining production line;
Be arranged on the turning operation cavity between the frame.
Wherein, described machine frame at two sides structure is identical and have a supporting frame respectively;
Two ends are fixed with leading block respectively on supporting frame;
The conveying that is wrapped between the leading block of two ends is with synchronously;
Be fixed with two running rollers between the conveyer belt, on supporting frame;
With the concentric belt pulley that is connected of running roller, belt pulley is connected with a motor by belt.
As the frame of above-mentioned structure, when motor rotation, the output shaft of motor rotates thereby drive running roller in the same way by the rotation of the belt wheel of band drive synchronously; When running roller rotated, the wheel sour jujube of running roller imposed on conveying synchronously with certain friction, and then band can correspondingly drive wirecord fabric along being with forward synchronously or carrying backward synchronously.
When wirecord fabric when band is transported to the opposite side frame synchronously along the conveying of a side frame, can its stage casing part be extended downward in the turning operation cavity by the operator, and utilize manual 180 ° of wirecord fabric upsets.Then above the conveying of opposite side frame is with synchronously, the another side of cord can be presented in face of the operator, the operator adopts normal stance, adopts conventional processing technology can implement the bag welt operation of wirecord fabric another side.
Aforesaid wirecord fabric low-angle cutting machine bag welt device has the following advantages and effect:
1, cutting machine bag welt device overall structure is simple, is easy to promote the use of.
2, need not to change existing wirecord fabric bag welt technology, and use described bag welt device to be easier to guarantee crudy.
When 3, the operator wraps welt to cord is two-sided, can adopt normal stance, not have any production safety hidden danger and can effectively reduce labour intensity.
Description of drawings
Fig. 1 is a kind of structural representation of existing wirecord fabric bag welt device;
Fig. 2 is the another kind of structural representation of existing wirecord fabric bag welt device;
Fig. 3 is the structure chart of wirecord fabric low-angle cutting machine bag welt device described in the utility model.
As shown in Figure 1-Figure 3, mainframe 11 hangs frame 12, is with 13 synchronously, steering spindle 14; Mainframe 21 is with 22 synchronously, steering spindle 23, conveyer belt 24;
Machine frame at two sides 31, turning operation cavity 32, supporting frame 33, leading block 34 is carried and is with 35 synchronously, running roller 36, belt wheel 37 is with 38 synchronously, motor 39.
The specific embodiment
Embodiment 1, and as shown in Figure 3, described wirecord fabric low-angle cutting machine bag welt device has a pair of symmetrically arranged machine frame at two sides 31.Between frame 31, be provided with a melt pit to serve as turning operation cavity 32.
Machine frame at two sides 31 has a supporting frame 33 respectively, and the leading block 34 at supporting frame 33 two ends is wound with conveying and is with 35 synchronously.
Be fixed with a running roller 36 between conveyer belt 35, the running roller 36 concentric earth's axis are established and are connected with a belt pulley 37.
When motor 39 runnings, motor 39 drives belt pulley 37 rotations by belt 38, thereby driving running roller 36 rotates in the same way, then utilize to carry synchronously with 35 friction the A face of wirecord fabric from a side frame 31, after 180 ° of turning operation cavity 32 upsets, the conveying that the B face of wirecord fabric is presented in opposite side frame 31 is with on 35 synchronously, and then the operator can wrap the welt operation to the B face of wirecord fabric.
More than get final product the major programme of wirecord fabric low-angle cutting machine bag welt device described in the utility model.
