[0035] A hand support plate 35 is provided at the top of the sliding sleeve block 32, a push block 36 is fixedly connected to one side of the hand support plate 35 and located above the sliding sleeve block 32, and an electric cylinder 37 is fixedly installed at the bottom end of the push block 36, the electric cylinder 37 and the sliding sleeve block 32 are fixedly connected, the electric cylinder 37 and the sliding sleeve block 32 are fixedly connected, the hand support plate 35 and the electric cylinder 37 are slidably connected, and the inner wall of the hand support plate 35 is a smooth surface.

[0036] The working principle of the anti-throw-out ceramic wheel throwing machine of the present invention is as follows:

[0037] Step 1: When the hand is supported and positioned, first, the concave support plate 1 is fixed to the ground platform with bolts, and at the same time, the controller 11 starts the reduction motor 27, and the reduction motor 27 drives the transmission screw 25 to rotate. The transmission screw 25 rotates inside the support frame 24, and the transmission screw 25 drives the connecting sleeve 26 to move left under the action of the thread transmission force, and the connecting sleeve 26 can drive the concave block 28 to move left. The concave block 28 causes the two connecting shafts 29 to move left, and the two connecting shafts 29 drive the right ends of the two sleeve rods 30 to move left respectively, and the other end of the sleeve rod 30 drives the push shaft 31 to move forward along the arc, and the push shaft 31 drives the sliding sleeve 32 to move forward along the arc. Another sliding sleeve 32 moves backward along the inner wall of the arc guide rail 34 along the arc, and the sliding sleeve 32 moves forward along the arc along the outer wall of the arc track 33 and the inner wall of the arc guide rail 34.

[0038] At the same time, the sliding sleeve block 32 drives the electric cylinder 37 to move forward along the arc, and the electric cylinder 37 drives the push block 36 to move forward along the arc, and the push block 36 makes the hand support plate 35 move forward along the arc, and the electric cylinder 37 pushes the push block 36 to move upward, and the push block 36 drives the hand support plate 35 to move upward, and a gap is generated between the hand support plate 35 and the sliding sleeve block 32. In this way, the height of the two hand support plates 35 and the distance between the two hand support plates 35 are adjusted so that both hands are respectively located on the two hand support plates 35.

[0039] Step 2: During sensing positioning, the protective cover 8 supports the sleeve plate 18, and the controller 11 starts the transmission motor 20. The transmission motor 20 drives the adjusting screw 19 to rotate. The adjusting screw 19 drives the sleeve slider 21 to move right under the action of the thread transmission force, and the sleeve slider 21 drives the vertical distance sensor 22 to move right. The sleeve slider 21 also drives the lateral distance sensor 23 to move right, so that the vertical distance sensor 22 performs distance sensing on the top of the ceramic blank, and the lateral distance sensor 23 can perform tilt distance sensing on the top of the ceramic blank. When the vertical distance sensor 22 and the lateral distance sensor 23 can sense the ceramic blank at a specified distance, the transmission motor 20 is turned off by the controller 11.

[0040] Step three, when throwing ceramics, the rotating motor 14 is started through the controller 11, and the concave support plate 1 supports the support block 12, the support block 12 supports the rotating motor 14, the rotating motor 14 drives the rotating shaft 13 to rotate, the rotating shaft 13 rotates inside the socket concave plate 15, and the concave support plate 1 provides a stable supporting force for the socket concave plate 15.

[0041] Then the rotating shaft 13 drives the sleeve concave plate 15 to rotate, the sleeve concave plate 15 makes the rotating block 16 rotate, the rotating block 16 drives the rotating table 17 to rotate, the rotating table 17 makes the throwing platform 10 rotate, and the throwing platform 10 rotates stably on the inner wall of the rubber sleeve 9. Then both hands are placed on both sides of the outer wall of the ceramic embryo body to squeeze, so that the ceramic embryo body can be squeezed upward and lengthened under the action of the rotating squeezing force, and at the same time, the outer wall of the rubber sleeve 9 blocks the impurities thrown out of the ceramic embryo body.

[0042] Step 4: During positioning and preventing the ceramic blank from being thrown out, when the top of the ceramic blank becomes higher, the driving motor 5 is started through the controller 11, and the driving motor 5 drives the linkage screw 4 to rotate, and the linkage screw 4 drives the threaded sleeve 6 to move up under the action of the thread transmission force, and the threaded sleeve 6 moves up along the inner wall of the support frame 3, and the threaded sleeve 6 drives the linkage bar 7 to move up, and the linkage bar 7 makes the protective cover 8 move up, and the protective cover 8 drives the rubber sleeve 9 to move up, and the rubber sleeve 9 is squeezed and moved up along the outer wall of the blank drawing platform 10. At the same time, the protective cover 8 drives the sleeve plate 18 to move up, and the sleeve plate 18 drives the adjusting screw 19 to move up, and the adjusting screw 19 makes the sleeve slider 21 move up, and the sleeve slider 21 drives the vertical distance sensor 22 and the lateral distance sensor 23 to move up synchronously, so that the vertical distance sensor 22 and the lateral distance sensor 23 can sense the distance of the top of the ceramic blank, until the distance value sensed by the lateral distance sensor 23 is the same as the distance value set by the controller 11, and then the driving motor 5 is turned off through the controller 11.

[0043] At the same time, the protective cover 8 drives the arc guide rail 34 to move upward, the arc guide rail 34 drives the arc track 33 to move upward, the arc track 33 makes the two sliding sleeves 32 move upward synchronously, the two sliding sleeves 32 respectively drive the electric cylinder 37 to move upward, the electric cylinder 37 makes the push block 36 move upward, the push block 36 drives the hand support plate 35 to move upward, which can ensure that the two hands move up with it, thereby ensuring that the soil of the ceramic body is prevented from being thrown out from the outside, and the effect of preventing impurities of the ceramic body from being thrown out is better.
