As an embodiment of the invention, belt pulleys 23 are arranged on the rotating shafts 22 on the upper part and the lower part of the workbench 1, and the two belt pulleys 23 are in transmission connection through belts 24 which are crossed in a splay shape; the left rotating shaft 22 is in transmission connection with an external driving motor through a transmission assembly. The belt pulley 23 and the belts 24 crossed in a splay shape can enable the rotation direction of the finished product die 5 to be opposite to that of the blank 2, and enable the relative angles and relative positions between the ejector head 34 and the spray head 6 and the finished product die 5 or the blank 2 to be the same at the same time, so that the angle of the spray head 6 towards the blank 2 can be always unchanged no matter the blank is in an oval structure or an asymmetric structure (such as a cam shape), and the glaze spraying quality is ensured.

As an embodiment of the invention, a first fixing rod 35 is vertically arranged at the lower end of the top 34, a second fixing rod 37 is fixedly arranged on the workbench 1 at the right front of the left first rotary table 21, an elastic friction belt 36 is arranged on the first fixing rod 35, the elastic friction belt 36 bypasses the rear side of the left rotary shaft 22 and is connected with the second fixing rod 37, the rotating speed of the rotary shaft 22 can be changed in real time according to the appearance of the blank 2, the glaze spraying thickness is uniform, and the glaze spraying quality is greatly improved. When in use, the rotating shaft 22 rotates by the same angle, the arc length of the blank 2 which runs through one side of the long shaft is larger than that of the short shaft, namely, the speed of the long shaft which runs through the spray head 6 is higher, the total spraying speed of the spray head 6 in unit time is constant, so that the thickness of the glaze spraying on the side of the major axis is smaller than that on the side of the minor axis, the thickness of the glaze spraying is uneven, the quality of the glaze spraying is affected, and therefore, through the arrangement of the elastic friction belt 36, when the long shaft side contacts with the top head 34, the first fixing rod 35 pulls the elastic friction belt 36 and presses the surface of the rotating shaft 22, the rotation speed of the rotation shaft 22 is slowed down by the frictional force between the elastic friction band 36 and the rotation shaft 22, and the friction force is larger on the side closer to the long shaft, so that the rotating speed of the rotating shaft 22 can be changed in real time according to the appearance of the blank body 2, the glaze spraying thickness is uniform, and the glaze spraying quality is greatly improved.

During the use, outside driving motor starts and drives pivot 22 synchronous rotation, and then makes finished product mould 5 and body 2 synchronous rotation on the first carousel 21, and the rotation of finished product mould 5 will drive its left mounting panel 3 through top 34 and remove again, if: initially, one side of a short shaft of the finished product mold 5 is abutted against the top head 34, when the finished product mold 5 rotates, the outer wall of the finished product mold 5 extrudes the mounting plate 3 on the left side leftwards through the top head 34, so that the rotating arm 42 on the left side is expanded outwards, the guide rod 45 moves backwards and simultaneously drives the rotating arm 42 on the right side to synchronously expand outwards, and the mounting plate 3 on the right side and the spray head 6 above the mounting plate 3 are driven to move rightwards; through the arrangement of the stop block 46 and the compression spring 47, the compression spring 47 can reset in the process that one side of the long axis of the finished product die 5 is in contact with the ejector head 34 and the other side of the short axis is in contact with the ejector head 34, the guide rod 45 is driven by the stop block 46 to move forwards, then the rotating arm 42 is closed inwards, and the ejector head 34 is enabled to be in contact with the outer surface of the finished product die 5 all the time, so that the distance from the spray head 6 to the blank body 2 is ensured to be constant all the time, and the glaze spraying quality is ensured; because the end part of the top head 34 always touches the outer wall of the finished product die 5 in use, the finished product die 5 and the top head 34 are worn, especially when one side of the long shaft of the finished product die 5 touches the top head 34, the pressure of the spring 47 is maximum at the moment, so that the friction force between the end part of the top head 34 and the finished product die 5 is larger, and the wear is easier, therefore, the friction force between the end part of the top head 34 and the finished product die 5 can be reduced through the arrangement of the rollers, the finished product die 5 is prevented from being worn, and the service life is prolonged; because the cantilever beam is hinged with the rotating arm 42, if the rotating arm 42 is fixedly connected with the mounting plate 3, along with the rotation of the finished mold 5, the mounting plate 3 will swing around the hinge point of the rotating arm 42 and the cantilever beam under the action of the rotating arm 42, at this time, although the distance between the mounting plate 3 and the outer wall of the finished mold 5 is not changed, but the angle between the mounting plate 3 and the outer wall of the finished product mold 5 can be slightly changed, the glaze spraying quality is influenced, therefore, the angle between the mounting plate 3 and the outer wall of the finished product mold 5 is ensured to be unchanged by arranging the slide block 31 and the slide groove, meanwhile, the installation plate 3 can drive the rotating arm 42 to rotate through the arrangement of the connecting block 32, the second strip-shaped groove 43 and the second upright post 44, the synchronous action is not influenced, therefore, the angle of the spray head 6 towards the blank body 2 is always unchanged through the arrangement of the connecting block 32 and the sliding block 31, and the glaze spraying quality is ensured; fixing the spray head 6 and adjusting the initial distance between the spray head 6 and the blank 2 through the binding band 64, then adjusting the initial angle of the spray head 6 by rotating the second turntable 61, connecting the second turntable 61 with the workbench 1 through the positioning hole 62 and the positioning pin 63 after the angle adjustment is finished, and limiting the second turntable 61; the belt pulley 23 and the belts 24 crossed in a splay shape can enable the rotation direction of the finished product die 5 to be opposite to that of the blank 2, and enable the relative angles and relative positions between the ejector head 34 and the spray head 6 and the finished product die 5 or the blank 2 to be the same at the same time, so that the angle of the spray head 6 towards the blank 2 can be always unchanged no matter the blank is in an elliptical structure or an asymmetric structure (such as a cam shape), and the glaze spraying quality is ensured; the rotation of the rotating shaft 22 by the same angle leads the arc length of the blank 2 on one side of the long axis to be larger than that of the blank on one side of the short axis, namely, the speed is higher when one side of the long axis passes through the spray head 6, the total spraying speed of the spray head 6 in unit time is constant, so that the thickness of the glaze spraying on the side of the major axis is smaller than that on the side of the minor axis, the thickness of the glaze spraying is uneven, the quality of the glaze spraying is affected, and therefore, through the arrangement of the elastic friction belt 36, when the long shaft side contacts with the top head 34, the first fixing rod 35 pulls the elastic friction belt 36 and presses the surface of the rotating shaft 22, the rotation speed of the rotation shaft 22 is slowed down by the frictional force between the elastic friction band 36 and the rotation shaft 22, and the friction force is larger on the side closer to the long shaft, so that the rotating speed of the rotating shaft 22 can be changed in real time according to the appearance of the blank body 2, the glaze spraying thickness is uniform, and the glaze spraying quality is greatly improved.
