[0001] The invention relates to the field of ceramic processing, in particular to an improved blank repairing machine. Background Art

[0002] Repairing the blank is one of the processes in the production of porcelain products. Since the surface of the blank is not very smooth, there are burrs on the edges, and some even have mold seams or slurry flow, etc., the blank needs to be further processed and smoothed with tools after it is dried in the shade. The main purpose is to make the surface of the blank smooth, the shape coherent, and regular, so that it can be suitable for glazing operations and kiln firing. It is the key link in finally determining the shape of the porcelain.

[0003] However, most of the current blank trimming machines use a carousel to drive the blank to rotate, and at the same time use a fixed-position blank trimming knife to trim the blank surface. However, during the blank trimming process driven by the carousel to rotate, the blank is prone to shifting, which will result in an insufficient trimming effect. After the blank surface is trimmed, the staff is required to trim the blank bottle mouth, which wastes time and manpower, resulting in low blank trimming efficiency. Summary of the invention

[0029] The stabilizing mechanism includes a transmission assembly 71, a transmission assembly 71 is provided between the bottom end of the turntable 4 and the output shaft of the servo motor 6, a worm 72 is welded on the top of the output shaft of the servo motor 6, a bidirectional screw 73 is welded on the top of the worm 72, a nut 74 is threadedly connected to the bidirectional screw 73, a sliding frame 75 is slidably connected to the support frame 2, and the sliding frame 75 is fixedly connected to the nut 74, two movable frames 76 are slidably connected to the mounting plate 3, and the two movable frames 76 are symmetrically arranged, and a reset spring 77 is connected between the mounting plate 3 and the two movable frames 76 by a hook, and three rollers 78 are rotatably connected to the two movable frames 76, and the three rollers 78 form a group, and the two groups of rollers 78 are used to limit the blank 5, and the two movable frames 76 are connected to a bevel frame 79 by bolts on the side away from each other, and the two bevel frames 79 are provided with a guide bevel.

[0030] The transmission assembly 71 is composed of two transmission wheels and a transmission belt. The bottom end of the turntable 4 is connected to a transmission wheel via a flat key, and the output shaft of the servo motor 6 is connected to a transmission wheel via a flat key. A transmission belt is sleeved between the two transmission wheels.

[0031] The trimming mechanism includes a mounting rod 81, the mounting rod 81 is welded to the two movable frames 76, a tool holder 82 is slidably connected to the mounting plate 3, the ends of the two mounting rods 81 close to each other are rotatably connected to a connecting rod 83, the tool holder 82 is rotatably connected to the two connecting rods 83, and a plurality of trimming knives 84 are fixedly connected to the tool holder 82, and the trimming knives 84 are used to trim the blank 5.

[0032] Initially, the blank 5 is placed on the turntable 4. First, the staff starts the servo motor 6, which drives the transmission assembly 71, the worm 72 and the bidirectional screw 73 to rotate. The rotation of the transmission assembly 71 drives the turntable 4 to rotate, and the rotation of the turntable 4 drives the blank 5 to rotate. The rotation of the bidirectional screw 73 drives the nut 74 to move up and down through the thread, and the up and down reciprocating movement of the nut 74 drives the sliding frame 75 to move up and down. When the nut 74 drives the sliding frame 75 to move upward, the sliding frame 75 will contact both bevel frames 79, and the sliding frame 75 will squeeze the two bevel frames 79 towards each other. The two movable frames 76 move in the direction of approaching each other, and the two movable frames 76 drive the two sets of rollers 78 to move in the direction of approaching each other. The blank 5 will contact the side of the two sets of rollers 78 that are close to each other. The two sets of rollers 78 will limit the blank 5, and the reset spring 77 will be compressed. The movement of the two movable frames 76 will drive the two mounting rods 81 to move away from each other, and the movement of the two mounting rods 81 will drive the two connecting rods 83 to swing away from each other. The swing of the two connecting rods 83 will jointly drive the tool holder 82 and a plurality of blank repairing The blade 84 moves in the direction away from the support frame 2, and the blank 5 will contact with the plurality of trimming blades 84. As the turntable 4 drives the blank 5 to rotate continuously, the plurality of trimming blades 84 will jointly trim the surface of the blank 5. When the blank 5 is trimmed, the nut 74 will drive the sliding frame 75 to move downward and reset, and the sliding frame 75 will be out of contact with the two bevel frames 79, and the reset spring 77 will reset. The reset spring 77 will reset and drive the two movable frames 76 to move and reset in the direction away from each other. The reset of the two movable frames 76 will respectively drive the two sets of rollers 78 and the two bevel frames 79 to move in the direction away from each other. The blank 5 will be out of contact with the two sets of rollers 78 when it is reset. The reset of the two movable frames 76 will respectively drive the two mounting rods 81 to move away from each other and reset. The reset of the two mounting rods 81 will respectively drive the two connecting rods 83 to swing toward each other and reset. The reset of the two connecting rods 83 will jointly drive the tool holder 82 and several trimming knives 84 to move and reset in the direction close to the support frame 2. The blank 5 will be out of contact with several trimming knives 84. In this way, the blank 5 is limited by the two sets of rollers 78, which can make the blank 5 more stable during the trimming process, thereby achieving a better trimming effect on the blank 5.

[0039] Initially, the soft-bristle brush roller 102 contacts the surface of the blank 5. When the worm gear 92 drives the bidirectional screw 73 to rotate, the bidirectional screw 73 will drive the pulley set 103 to rotate. The rotation of the pulley set 103 will drive the soft-bristle brush roller 102 to rotate. The brush roller will brush off the blank chips attached to the surface of the blank 5, thereby further improving the blank repairing efficiency of the blank 5.
