Summary of the invention

At above-mentioned situation, the purpose of this utility model provides the manual wiper mechanism of a kind of label printing machine dabber, it is the further measure that realizes manual cleaning function on the basis of patent power washer structure formerly, it not only can make the power washer structure but also can make standardization, generalization degree height as required, be convenient to production, management, the manual wiper mechanism that convenient for maintaining and product cost reduce.

For achieving the above object, the manual wiper mechanism of a kind of label printing machine dabber, it comprises the chain of transferring power, little driven sprocket, big driven sprocket, dabber axle and the cushion cover that is fixed on the dabber axle, driving lever, the dabber that rotates by the driving lever band, be contained in the axle sleeve in the end plate of the dabber left and right sides, be fixed in the little axle on the dabber first member plate, be contained in the sliding sleeve that is stuck in again on the little axle in the driving lever groove, be fixed in the key on the dabber end plate, bearing and be positioned on the bearing the axle and roller, be fixed in the left riser on the printing machine lathe bed, right riser, be fixed in the left bearing on the left riser, be fixed in the left bearing cover on the left bearing, be fixed in the right bearing on the right riser, be fixed in the right bearing cover on the right bearing, be individually fixed in a pair of hinge wheel that left bearing cover and right bearing put, be fixed in the outer grooved cam that right bearing puts, its medium and small driven sprocket is fixed on left bearing and puts, big driven sprocket is fixed on the dabber axle through unilateral bearing, they are connected with a synchronous chain gear apparatus through the chain of transferring power, this synchronous sprocket wheel device comprises the chain wheeling support that is fixed in the printing machine lathe bed, be fixed in the sprocket sleeve on the chain wheeling support, screw rod and T type nut and be fitted in plain washer on the screw rod, spring washer installs sprocket shaft bearing and synchronous sprocket wheel on the described sprocket sleeve.

For implementation structure optimization, its further step is: the unilateral bearing outer end is provided with back-up ring and screw, and unilateral bearing is radially established connecting key and holding screw.Be provided with the bearing spacer between the sprocket shaft bearing of synchronous sprocket wheel internal diameter.

The utility model is used on the basis of patent " label printing machine dabber power washer structure " formerly and has removed parts such as two-way small machine and frequency converter, replace to have designed and comprise that little driven sprocket is fixed on left bearing to put, big driven sprocket is fixed on the dabber axle through unilateral bearing, they are connected with a synchronous chain gear apparatus through the chain of transferring power, this synchronous sprocket wheel device comprises the chain wheeling support that is fixed in the printing machine lathe bed, be fixed in the sprocket sleeve on the chain wheeling support, screw rod and T type nut and be fitted in plain washer on the screw rod, spring washer, install the technical scheme of sprocket shaft bearing and synchronous sprocket wheel on the sprocket sleeve, solved the manual wiper mechanism complex structure of existing label printing machine dabber, power washer structure adaptation marketability is narrow and can't adapt to standardization, the modern production that the generalization degree is had relatively high expectations, management and defective such as be inconvenient to keep in repair; Also solved the difficult problem that the protoplanet gear is bad easily, need frequent replacing simultaneously.

The utility model is compared the beneficial effect that is produced with background technology:

1, owing to having adopted the main drum part of former power washer structure constant, only on machine main drive regulating wheel, having done partly to improve, just realized the purpose that dabber manually cleans, and then replaced the manual wiper mechanism that utilizes the freewheel clutch principle, complex parts such as big internal gear in the former mechanism, planetary gear, central gear have been cancelled, make part processing simple, the operation noise reduces, and working service is convenient, and product cost obviously descends.2, because electronic and manually all shared a kind of dabber has improved generalization of parts and standardization level, give and produce and manage and keep in repair and brought convenience, improved production efficiency and management benefit.Protoplanet gear defective bad easily, that need often to change has also obtained solution.

Clear Xian that it is fit to the label printing machine dabber of different model, specification uses.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
