Description
Technical field
The present invention relates to a kind of cord calender draw-gear.
Background technology
Casing ply is airtyred skeleton, and by which floor rubberized cord being fitted forms, and it bears the most of load acted on tire.
For conventional tyre, the number of plies of casing ply is generally even number as 4-18 layer.The number of plies of radial is odd-level, as 1-5 layer.Tire texture is produced by cord calender.Calender comprises left frame and right frame, between left frame and right frame, be provided with roller, is coated with cord fabric sizing material from calender cord surface out.So that bonding multi-layer cord fabric, upper end on front side of left frame and right frame is respectively equipped with the traction roll stand of stretching out forward, be separately installed with carry-over pinch rolls and lower carry-over pinch rolls between the top and bottom of the described carry-over pinch rolls of left and right sides, coat the cord of sizing material, draw then rolling by carry-over pinch rolls.After gluing, easily form bubble in the middle of cord, if bubble removes not in time, finally will cause the cord delamination of tire, even cause cord and tyre surface delamination.
Summary of the invention
For existing problem, the object of the present invention is to provide a kind of can in time by the cord calender draw-gear of the removal of bubbles in cord.
To achieve these goals, technical scheme of the present invention is: a kind of cord calender draw-gear, comprise left frame and right frame, upper end on front side of described left frame and right frame is respectively equipped with the traction roll stand of stretching out forward, carry-over pinch rolls and lower carry-over pinch rolls are separately installed with between the top and bottom of the described traction roll stand of left and right sides, it is characterized in that: the middle part on front side of the described traction roll stand of left and right sides is stretched out all forward and formed punching roller installing plate, this punching roller installing plate has the strip through-hole extended before and after length, extend about the center line of this strip through-hole, the leading inside of described punching roller installing plate is provided with screw rodb base, screw mandrel is connected with punching roller bearing seats through screw rodb base, described punching roller bearing seat is in the inner side of punching roller installing plate, described punching roller bearing seats is also provided with slide block, described slide block reaches in strip through-hole, and be slidably connected with strip through-hole, the roll shaft at punching roller two ends is set in the bearing in the punching roller bearing seats of left and right sides,
The roll surface of described punching roller is distributed with some bolt blind holes, in these bolt blind holes, is provided with perforating needle, described perforating needle is made up of lower thread section and upper taper section, and described perforating needle is threaded in bolt blind hole by lower thread section.
Adopt such scheme, punching roller is set between drawing rolls, allows cord in distraction procedure, through punching roller.Perforating needle on punching roller pricks out some pin holes on cord, thus by the removal of bubbles between casing ply.Ensure the quality of tire production.
By turning screw mandrel, thus make the slide block of punching roller movable in strip through-hole, thus the front and back position of adjustment punching roller.
Perforating needle adopts with roller and is threaded, and is convenient for changing like this.
In technique scheme: described traction roll stand is the T-shaped frame be made up of transverse plate and longitudinal plate, the described traction roll stand of left and right sides is connected in left frame and right frame respectively by transverse plate, described longitudinal plate is obliquely installed, and described upper carry-over pinch rolls and lower carry-over pinch rolls are arranged between longitudinal plate of described traction roll stand of left and right sides.
In technique scheme: the transverse plate of described traction roll stand, longitudinal plate and punching roller installing plate are one-body molded.Produce easy for installation.
In such scheme: the center line of described screw rod, base and perforating needle on the same line.Be convenient to processing like this.
The invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, between the drawing rolls of cord calender draw-gear, arrange perforated roll, like this, just bubble is wherein got rid of by punching when cord is produced, ensure the quality of tire product, avoid delamination.The present invention simultaneously can easily adjust the front and back position of punching roller, is more suitable for producing.
