Description
Technical field
The utility model relates to a kind of tire building machinery, specifically a kind of gapless belt drum.
Background technology
Existing belt drum, form primarily of main shaft, left and right positioning disk, air cylinder device, slide block 7, drum surface plate 5, it all adopts the drum surface plate of same size, because the size of drum surface plate is all identical, in order to ensure under the effect of air cylinder device, drum surface plate can open and shrink, therefore, seam drum surface plate must have been adopted to design, when opening, to gap be left between drum surface plate and drum surface plate, therefore must mix the base part of rubber cushion to overcome clearance issues.Owing to mixing rubber cushion on drum surface plate, belt drum is made to be apertured non-real round shape state when opening, thus produce the girth error of pressure roller roll extrusion rear tyre tread rubber composite members and cause the inhomogeneities of the rear packing of its laminating, affect laminating quality and the form accuracy of tire tread glue composite members.
Summary of the invention
The purpose of this utility model is the shortcoming overcoming existing belt drum, provides a kind of gapless belt drum.Be intended to make belt drum be seamless proper circle state when opening, thus reduce the girth error of pressure roller roll extrusion rear tyre tread rubber composite members, greatly promote quality and the form accuracy of tire tread glue composite members, make its more smooth, rounding, thus improve the qualification rate of tire tread glue composite members.
The utility model, mainly comprise main shaft, left and right positioning disk, air cylinder device, line slideway auxiliary, slide block, drum surface plate and connecting rod, left and right positioning disk and air cylinder device are arranged on main shaft, air cylinder device is between left positioning disk and right positioning disk, interstage sleeve is provided with between left positioning disk and right positioning disk, described air cylinder device is by cylinder, cylinder cap and piston composition, piston is fixedly connected on main shaft, cylinder cap fixed seal connection is in cylinder port, wherein cylinder can horizontally slip on main shaft, cylinder block is divided into left air chamber and right air chamber by described piston, main shaft is respectively equipped with the left pore and right pore that are communicated with left air chamber and right air chamber, the large slide block of plural block that described slide block is equal and alternate successively by block number and small slide block form, in the outside of large slide block and small slide block, correspondence is fixedly connected with big drum panel and side drum panel respectively, in the inner side of large slide block and small slide block, is articulated and connected by pin is corresponding corresponding with large small rod respectively, on the lateral wall of cylinder, be provided with supporting seat, large small rod is connected with large small slide block with supporting seat respectively by pin, and line slideway auxiliary is arranged between left and right positioning disk and slide block, is used for realizing rising and the decline of slide block.
The utility model, is provided with Limit screw at main shaft left end, and screw rod is provided with adjusting nut and position-arresting disk, by them and the maximum gauge be arranged on when the sprue be positioned at inside left positioning disk on main shaft opens to limit laminating drum and shrinks and minimum diameter; In the left side of cylinder, be provided with spacing ring; Described position-arresting disk is provided with complex root guide post, and described guide post is connected with cylinder through left positioning disk.
The utility model, the length of big connecting rod is longer than small rod, and during assembling, big connecting rod, large slide block are connected successively with big drum panel; Small rod, small slide block are connected successively with side drum panel.
The utility model, its operation principle is: when laminating drum does not work, and size drum surface plate is contraction state, forms certain difference in height diametrically, and there is certain gap each other.During work, size drum surface plate opens and forms seamless proper circle state, and adsorbs laminating tread rubber composite members by the magnet base that drum surface plate assembles.Owing to have employed the large small rod that length differs, make connecting rod in swing process different from the angle between gripper shoe all the time, this ensures that there size drum surface plate non-interference in motion process.During laminating drum work, compressed air on forming machine enters the right chamber of cylinder by the pore on main shaft, cylinder drives supporting seat to slide to the right under compressed-air actuated effect, connecting rod swings certain angle along with the motion of supporting seat, slide block circumferentially opens under the guiding of left and right positioning disk simultaneously, when reach adjusting nut adjust the maximum functional diameter of gapless belt drum time, cylinder stops sliding, drum surface plate is raised to extreme higher position, gapless belt drum opens up into maximum functional diameter, at this moment start on gapless belt drum, be wound around laminating tread rubber composite members.Tread rubber composite members, after the roll forming of winding layer pressing roller, sends command adapted thereto control transmission ring by forming machine and moves to assigned address and tread rubber composite members is clamped.At this moment, forming machine sends instruction and enters the left chamber of cylinder to pneumatic system control compressed air, cylinder drives supporting seat to slide left under compressed-air actuated effect, and slide block is circumferentially retracted, drum surface plate drops to extreme lower position, now laminating drum is contracted to minimum diameter, and be wound around superincumbent tread rubber composite members and be separated with it, then transmission ring removes tread rubber composite members.So far, a working cycles of tire tread glue composite members assembly under proper circle state is completed.
The utility model, owing to being employing gapless drum surface plate structure, instead of originally has seam drum surface plate structure, belt drum is made to be seamless proper circle state when opening, thus reduce the girth error of pressure roller roll extrusion rear tyre tread rubber composite members and the inhomogeneities of packing, greatly promote quality and the form accuracy of tire tread glue composite members, make its more smooth, rounding, thus improve the qualification rate of tire tread glue composite members, create more market efficiency.
The utility model, its major advantage is: 1, adopt gapless drum surface plate structure to replace traditional having seam drum surface plate structure, improve tire tread glue composite members shaping time quality and precision; 2, gapless drum surface plate structure is adopted, tire tread glue composite members is made to be assembly under seamless proper circle state, precision is high, effectively prevent the inhomogeneities of polygon situation that tire tread glue composite members occurs after pressure roller roll extrusion and packing, be particularly suitable for the production of high-performance meridian tire.
