Detailed ways

The automatic step-by-step feeding mechanism includes a feeding conveyor belt 2 and a feeding manipulator 3 fixed on the feeding mechanism frame body 1, and a feeding conveyor belt 6 and a feeding manipulator 3 fixedly arranged on the feeding mechanism frame body 5. The transmission mechanism 4 provided between the feeding conveyor belt 2 and the unloading conveyor belt 6, the transmission mechanism 4 is formed by a vertical cross-section that is fixed between the loading mechanism frame body 1 and the unloading mechanism frame body 5. body and a transmission plate 8, the transmission plate 8 is movably arranged in the groove between the two upper beams 20 of the square-shaped frame body, and the two lower beams 21 of the square-shaped frame body are arranged at intervals from left to right The first jack-up cylinder 10, the second jack-up cylinder 11 and the 3rd jack-up cylinder 12, the output shafts of these three jack-up cylinders are all connected with the lower bottom surface of the transmission plate 8 by the fixed block 13, in the shape of a square Two lower beams 21 of the frame body are fixedly provided with two lead screw bearing blocks 15, and a lead screw 14 is arranged between the two lead screw bearing blocks 15, and the lead screw 14 is fixedly connected with the lead screw motor 16. A lead screw nut 17 is arranged on the lead screw nut 17, and a cam follower 18 is fixedly arranged on the lead screw nut 17. The two cams of the cam follower 18 are movable respectively arranged in two 1-shaped cam lugs 19, and the two cam lugs 19 The upper end of the upper end is fixedly arranged on the front and rear sides of the lower bottom surface of the transmission plate 8.

On the two upper beams 20 of the frame body of the square shape, there are material basket support blocks 9, and every four material basket support blocks 9 form a positioning station for the material basket. A basket positioning station.

The biggest advantage of this mechanism is that the loading and unloading process does not take time alone. The traditional automatic loading and unloading and punching method is the "serial mode" of "loading - punching - unloading", but the fully automatic loading and unloading process and the punching process in this patent are "parallel mode", that is, in the equipment The loading and unloading movement is completed during the drilling process, which can effectively save time and improve equipment production efficiency. Secondly, the traditional automatic loading and unloading punching machine usually cannot load more than 40 pieces at a time, resulting in the need for frequent manual loading and unloading. However, the patented loading and unloading mechanism can place raw porcelain to be processed at the loading position each time. 200 tablets.

Put the bracket with the green tile tray on the feeding side of the timing belt 2 of the feeding mechanism, run the equipment, the timing belt motor starts, and the timing belt drives the green tile bracket to move; when the bracket moves to the feeding manipulator 3 When it is directly below, the positioning cylinder lifts up to position the bracket; a pair of tray sorting cylinders stretch out to tidy up the stacked green ceramic trays; The transmission plate 8 can move left and right under the action of the transmission plate lead screw motor 16 and the leading screw 14. In addition, the three transmission plates installed below the transmission plate lift up the cylinder to make the transmission plate move up and down; After one station, the conveying plate is lifted up, the conveying plate is moved to the right, and the conveying plate is lowered, so that the green ceramic sheet tray moves from the positioning pit of the conveying plate to the first basket positioning station, and from the first station of the conveying mechanism Move to the second station and reciprocate in this way to make the green ceramic sheet tray move backwards to punch holes for the green ceramic sheet. After the punching of the green ceramic sheet is completed, the transmission mechanism will continue to move it to the right to reach the unloading mechanism. The unloading mechanism has the same structure and working principle as the loading mechanism, and is used to complete the output of the product.
