Abstract
The invention discloses a novel traction perforating device of a cord fabric calender. The novel traction perforating device comprises a left frame and a right frame, wherein traction roller racks extending forwards are respectively arranged at the upper ends of the front sides of the left frame and the right frame; upper traction rollers and lower traction rollers are respectively mounted between the upper ends and the lower ends of the traction roller racks at the left side and the right side; perforating roller mounting plates extending forwards are both arranged in the middle of the front sides of the traction roller racks at the left side and the right side; perforating rollers are mounted between the perforating roller mounting plates at the left side and the right side; a plurality of bolt blind holes are formed in the surfaces of the perforating rollers; perforating needles are in threaded connection with the surfaces of the perforating rollers. The novel traction perforating device disclosed by the invention is reasonable in design; the perforating rollers are arranged between the upper traction rollers and the lower traction rollers of the novel traction perforating device of the cord fabric calendar, so that in the cord fabric production process, the bubbles can be eliminated by perforation, the quality of the tire product can be ensured, and the delamination can be avoided.
Description
Technical field
The present invention relates to a kind of novel cord calender traction perforating device.
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 novel cord calender of the removal of bubbles in cord traction perforating device.
To achieve these goals, technical scheme of the present invention is: a kind of novel cord calender traction perforating device, 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 equipped with the punching roller installing plate stretched out forward, between the described punching roller installing plate of left and right sides, punching roller is installed, the roll surface of described punching roller is distributed with some bolt blind holes, in these bolt blind holes, perforating needle is installed, described perforating needle is made up of lower thread section and upper taper section, described perforating needle is threaded in bolt blind hole by lower thread section, the length of described thread segment is greater than the half of perforating needle length.
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.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.
The invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, perforated roll is set between the drawing rolls of novel cord calender traction perforating device, like this, just bubble is wherein got rid of by punching when cord is produced, ensure the quality of tire product, avoid delamination.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of punching roller.
Fig. 3 is the structural representation of perforating needle.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described:
Embodiment 1
As Figure 1-3: novel cord calender traction perforating device of the present invention is made up of parts such as left frame 1, right frame 2, traction roll stand 3, upper carry-over pinch rolls 4, lower carry-over pinch rolls 5, punching roller installing plate 3a, punching rollers 6.
Stretcher roll (not shown in FIG.) is provided with between left frame 1 and right frame 2.Cord is fitted between these rollers.This does not repeat at this for prior art.
Upper end on front side of left frame 1 and right frame 2 is respectively equipped with the traction roll stand 3 of stretching out forward, traction roll stand 3 is the T-shaped frame be made up of transverse plate and longitudinal plate, the traction roll stand 3 of left and right sides is connected in left frame 1 and right frame 2 respectively by transverse plate, longitudinal plate top is obliquely installed side backward, and upper carry-over pinch rolls 4 and lower carry-over pinch rolls 5 are arranged between longitudinal plate of the traction roll stand 3 of left and right sides.Middle part on front side of the traction roll stand 3 of left and right sides is equipped with the punching roller installing plate 3a stretched out forward, draws longitudinal plate of roll stand 3, transverse plate and punching roller installing plate 3a and is formed in one.Carry-over pinch rolls 4 and lower carry-over pinch rolls 5 are separately installed with between the top and bottom of the traction roll stand 3 of left and right sides, punching roller 6 is installed between the punching roller installing plate 6 of left and right sides, specifically, the upper and lower sides and punching roller installing plate 6 of longitudinal plate are respectively equipped with bearing block, and the roll shaft of upper carry-over pinch rolls 4, lower carry-over pinch rolls 5 and punching roller 6 is set in the bearing in bearing block.
