Description
Technical field
The utility model relates to a kind of cotton tyre cord calender.
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.
Utility model content
For existing problem, the purpose of this utility model be to provide a kind of can in time by the cotton tyre cord calender of the removal of bubbles in cord.
To achieve these goals, the technical solution of the utility model is: a kind of cotton tyre cord calender, 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 perforating needles.
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.
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 beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, between the drawing rolls of cotton tyre cord calender, 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.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Embodiment 1
As shown in Figure 1: cotton tyre cord calender of the present utility model 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.Be separately installed with carry-over pinch rolls 4 and lower carry-over pinch rolls 5 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, the roll surface of punching roller 6 is distributed with some perforating needle 6a.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.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
