Description
Technical field
The utility model relates to a kind of coating machine, specifically refers to a kind of Wheel-type retractable frame of coating machine.
Background technology
Coating machine is produced for the coating of non-drying glue or double faced adhesive tape etc.The base cloth of rolling is coated with to glue, coating or the ink etc. of last layer specific function, and rolling after drying.Wherein retractable frame is for the base cloth of rolling being unreeled or by the specialized equipment of the finished product rolling that gluing machines.The connect material structure of retractable frame of the change of lap of some coating machines is generally: include one and rotate the cross frame arranging, the two ends of cross frame horizontal direction are respectively equipped with forward and backward change of lap axle, and cross frame vertical direction two ends are respectively equipped with upper and lower deflector roll.In the time of change of lap, cross frame rotates, and the position of forward and backward change of lap axle is replaced mutually.The shortcoming that this traditional retractable frame exists: before its horizontal direction, spacing between rear change of lap axle is longer than, spacing between lower guide roll, the shape that entirety retractable frame assumes diamond in shape, in the time that change of lap operates, it is very high that it rotates needed height, space hold volume is large, and, along with constantly unreeling of rear change of lap axle, the upper base cloth amount of rear change of lap axle is fewer and feweri, and base cloth on front change of lap axle volume also keeps complete, therefore, before, stressed difference on rear change of lap axle is increasing, but, the retractable frame that entirety assumes diamond in shape, before making, between rear change of lap axle, torque difference is exaggerated, balance between the two is also very difficult to keep, rear change of lap axle can be shaken because of unbalance in the time unreeling, thereby affect the subsequent job of coating machine.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and a kind of Wheel-type retractable frame that can improve the coating machine that unreels balance is provided.
For achieving the above object, the technical solution of the utility model is to be provided with the relative left side of pair of parallel in described frame, right support, a described left side, between right support, rotate and be provided with central rotating shaft, the both sides of described central rotating shaft and relatively left, the inner side of right support is linkedly set with a pair of round turntable, on described round turntable, be symmetrically arranged with at least two air-expanding shafts take central rotating shaft as axis of symmetry circumference, and these two air-expanding shafts rotate and are arranged on round turntable, the both sides of described frame are respectively arranged with the first motor and the second motor, this first motor drives two air-expanding shafts to rotate, the second described motor drives round turntable to rotate.
By this setting, adopt the supporter of round turntable as air-expanding shaft, due to its circular symmetric structure, therefore, there will not be moment amplification effect, balance is good, and round turntable overall volume is large, can keep better the balance of air-expanding shaft.
Further arrange is that described right support is the frame type support of sealing, this frame type support includes left and right wall and inner chamber, on described central rotating shaft, be linkedly set with the big gear wheel that is positioned at inner chamber, in the inner chamber of described frame type support, rotate and be provided with pinion shaft with respect to the avris of big gear wheel, on this pinion shaft, be provided with the miniature gears engaging with big gear wheel transmission, and the right-hand member of this pinion shaft stretches out on the right wall of frame type support and its and is linkedly set with power input gear, and the second described motor coordinates with this power input gear transmission.
By this setting; right support is set to the frame type support of sealing, and big gear wheel and miniature gears engagement are arranged in the inner, therefore; prevent that the dust accretions in coating machine workshop is on big gear wheel and miniature gears ideally; keep the clean of big gear wheel and miniature gears, thereby reduced transmission resistance, improved driving efficiency; in addition; the noise of large big gear wheel and miniature gears engaged transmission is also sealed by frame type support, greatly reduces the noise in workshop, protection workman's hearing safety.
In sum, the utility model has the advantages that structure arranges rationally, balance is good, and driving efficiency is high, and noise is low.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
