[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] See also Figure 1-3 As shown, the present invention is a raw material drying device for ceramic production, including a shell 1, a feed port 2, a stirring shaft 3, a stirring rod 4, a heating wire 5 and a driving motor 11. The feed port 2 and the driving motor 11 are arranged outside the shell 1, and a first transmission wheel 17 is arranged on the output end of the driving motor 11. The first transmission wheel 17 is connected to the second transmission wheel 19 through a belt 18. The second transmission wheel 19 is fixedly connected to a rotating rod 20. A fixed bracket is arranged on the top of the shell 1. The rotating rod 20 is rotatably connected to the fixed bracket. The other end of the rotating rod 20 on which the second transmission wheel 19 is installed is fixedly installed with a first bevel gear 22. A stirring shaft 3 is arranged inside the shell 1, one end of the stirring shaft 3 extends from the top of the shell 1 to the outside of the shell 1, a second bevel gear 23 is fixedly arranged on the outside, the first bevel gear 22 is meshed and connected with the second bevel gear 23, a plurality of stirring rods 4 are arranged on the stirring shaft 3, and a heating wire 5 is arranged on the plurality of stirring rods 4; a compression spring 10 is arranged inside the shell 1, a heat shrink film 9 is arranged on the outside of the compression spring 10, the other side of the compression spring 10 installed with the shell 1 is fixedly connected with the slide bar 7, the slide bar 7 is slidably connected with the slide groove 8, and an arc-shaped clamping block 6 is fixedly installed on the other side of the slide bar 7 connected to the compression spring 10.

[0034] Among them, the stirring rods 4 should be arranged in parallel so that the heating wire 5 can be installed on the stirring rods 4; the heating wire 5 should be arranged symmetrically about the circumference of the rotation center to make the device more stable during the rotation and stirring process; the compression spring 10 in the shell 1 is always in a compressed state to ensure that the clamp 6 can be close to the stirring shaft 3, and the ceramic raw material above will not leak into the lower chamber.

[0035] When using this raw material drying device, the ceramic raw material is put into the feed port 2, and then the switch of the driving motor 11 is turned on. The output end of the driving motor 11 drives the first transmission wheel 17 to rotate, and the first transmission wheel 17 drives the second transmission wheel 19 to rotate through the belt 18. The second transmission wheel 19 drives the first bevel gear 22 to move through the rotating rod 20, and the first bevel gear 22 is meshed with the second bevel gear 23 to drive the stirring shaft 3 to rotate; the stirring shaft 3 rotates to drive the stirring rod 4 to stir the ceramic raw material in the chamber, and at the same time, the switch of the heating wire 5 is turned on to dry the ceramic raw material in the chamber; because the clamping spring 10 is always in a compressed state, the clamping block 6 is always close to the stirring shaft 3 to prevent the upper ceramic raw material from leaking into the lower chamber. As the temperature in the chamber continues to rise, the heat shrinkable film 9 also begins to shrink until the heat shrinkable film 9 shrinks to a tension greater than the elastic force of the clamping spring 10, and the clamping block 6 begins to separate from the stirring shaft 3, so that the fully dried ceramic raw material above enters the lower chamber from the gap.

[0036] Example 2

[0037] See also Figure 1-5 As shown, this raw material drying device for ceramic production also includes a crankshaft 12, a rotating block 13, a hammer handle 14, a spring 15 and a hammer head 16. The output end of the driving motor 11 extends into the shell 1, and the output end is fixedly connected to the crankshaft 12. The other end of the crankshaft 12 connected to the driving motor 11 is rotatably connected to the shell 1, so that the crankshaft 12 can rotate in the chamber; the crankshaft 12 is sleeved with a rotating block 13, and the bottom of the rotating block 13 is fixedly connected to the hammer handle 14, and the end of the hammer handle 14 away from the rotating block 13 is fixedly connected to the spring 15, and the end of the spring 15 connected to the hammer handle 14 is fixedly connected to the hammer head 16; an electric push rod 25 is arranged at the bottom of the shell 1, and the push rod of the electric push rod 25 is fixedly provided with a push plate 26, and a mounting groove is arranged at the bottom of the device, and a discharge door 24 is detachably installed on the mounting groove.

[0038] Among them, a groove is provided on the crankshaft 12, and the rotating block 13 is sleeved with the crankshaft 12 at the groove, so that when the crankshaft 12 rotates, the groove can play a positioning role for the rotating block 13; when the crankshaft 12 has not rotated to the bottom, the hammer head 16 has already contacted with the bottom surface of the device, ensuring that the crankshaft 12 continues to rotate, driving the hammer head 16 to contact the ceramic raw material on the bottom surface and squeeze it; in order to make the push plate 26 and the hammer head 16 work together, the working cycle of the electric push rod 25 is adapted to the drive motor 11.

[0039] When this raw material drying device is used, the drive motor 11 is started, and the output end of the drive motor 11 drives the crankshaft 12 to rotate. Due to the influence of the gravity of the hammer head 16, the hammer handle 14 is always vertically downward during the rotation of the crankshaft 12. Before the convex shaft of the crankshaft 12 rotates to the lowest point, the hammer head 16 has already contacted the ceramic raw material on the bottom surface of the device, and then the crankshaft 12 continues to rotate to drive the ceramic raw material in the chamber of the hammer head 16, and at the same time the spring 15 is squeezed and compressed; during the squeezing process, the hammer head 16 will push the bottom ceramic raw material to the front of the push plate 26, and in the drive After the motor 11 controls the crankshaft 12 to rotate the hammer head 16 to the top of the electric push rod 25, the electric push rod 25 starts to drive the push plate 26 to flatten the ceramic raw materials in front in the device. Before the hammer head 16 falls again, the electric push rod 25 completes its contraction. As the electric push rod 25 starts periodically, it cooperates with the hammer head 16 controlled by the crankshaft 12; after the device stops, the discharge gate 24 is removed, and the electric push rod 25 is manually started. The push plate 26 of the electric push rod 25 extends out to push all the squeezed and dried ceramic raw materials in the device out of the slot where the discharge gate 24 is installed.

[0040] Example 3

[0041] Based on the above-mentioned embodiments 1 and 2, the method for using the raw material drying device for ceramic production comprises the following steps:

[0042] Step 1: Put the ceramic raw material into the feed port 2, then turn on the switch of the driving motor 11, the output end of the driving motor 11 drives the first transmission wheel 17 to rotate, the first transmission wheel 17 drives the second transmission wheel 19 to rotate through the belt 18, the second transmission wheel 19 drives the first bevel gear 22 to move through the rotating rod 20, the first bevel gear 22 is meshed with the second bevel gear 23, and drives the stirring shaft 3 to rotate;

[0043] Step 2: The stirring shaft 3 rotates to drive the stirring rod 4 to stir the ceramic raw materials in the chamber, and at the same time, the switch of the heating wire 5 is turned on to dry the ceramic raw materials in the chamber;

[0044] Step 3: The compression spring 10 is always in a compressed state, so the clamp block 6 is always close to the stirring shaft 3 to prevent the upper ceramic raw material from leaking into the lower chamber. As the temperature in the chamber continues to rise, the heat shrink film 9 also begins to shrink until the heat shrink film 9 shrinks to a tension greater than the elastic force of the compression spring 10, and the clamp block 6 begins to separate from the stirring shaft 3, allowing the fully dried ceramic raw material above to enter the lower chamber from the gap;

[0045] Step 4: Start the drive motor 11, which drives the crankshaft 12 to rotate in the chamber of the device, and drives the rotating block 13 set on the crankshaft 12 to move. Due to the influence of the gravity of the hammer head 16, the hammer handle 14 is always vertically downward. Before the convex shaft of the crankshaft 12 rotates to the lowest point, the hammer head 16 has already contacted the ceramic raw material at the bottom of the device. The crankshaft 12 continues to rotate, the spring 15 is compressed, and the hammer head 16 squeezes and flattens the ceramic raw material at the bottom. The hammer head 16 pushes the bottom ceramic raw material to the front of the push plate 26 as the crankshaft 12 rotates, and then the hammer head 16 moves upward with the crankshaft 12, and the electric push rod 25 extends to drive the push plate 26 to flatten the ceramic raw material in front of the device, and then quickly resets;

[0046] Step 5: After the ceramic raw materials are squeezed and dried, the discharge gate 24 is removed from the device, and the electric push rod 25 is manually started to push the ceramic raw materials in the device out of the installation slot of the discharge gate 24, thereby completing the collection of the processed ceramic raw materials.

[0047] The working principle of the present invention is as follows: while the driving motor 11 drives the crankshaft 12 to rotate, it also drives the stirring shaft 3 to rotate through the wheel belt transmission. The stirring shaft 3 is provided with a stirring rod 4 and a heating wire 5 to stir and dry the ceramic raw materials in the chamber. A clamping block 6, a heat shrinkable film 9 and a compression spring 10 are provided at the bottom of the chamber. When the temperature is just rising and drying begins, the elastic force of the compression spring 10 is greater than the tension of the heat shrinkable film 9, so that the clamping block 6 is tightly attached to the stirring shaft 3 to prevent the upper ceramic raw materials from entering the lower chamber. The heat shrinkable film 9 will shrink as the temperature in the chamber rises, until the heat shrinkable film 9 shrinks to the point where its tension is greater than the elastic force of the compression spring 10, and the clamping block 6 begins to separate from the stirring shaft 3, so that the ceramic raw materials stirred and dried in the chamber enter the lower chamber from the gap; the output of the driving motor 11 The end is connected to the crankshaft 12, driving the crankshaft 12 to rotate inside the device, and the crankshaft 12 drives the hammer handle 14 and the hammer head 16 to move. When the cam of the crankshaft 12 has not yet rotated to the lowest point, the hammer head 16 has already contacted the ceramic raw material. As the crankshaft 12 continues to rotate, the spring 15 is compressed, and the hammer head 16 squeezes the ceramic raw material and pushes it to the front of the push plate 26. After the crankshaft 12 drives the hammer head 16 to separate from the ceramic raw material, the electric push rod 25 starts to drive the push plate 26 to flatten the ceramic raw material accumulated in the front in the device, and then quickly completes the reset. After the drying of the ceramic raw material is completed, the discharge door 24 of the device is disassembled, and the electric push rod 25 is manually started. The electric push rod 25 pushes the processed ceramic raw material in the device out of the mounting groove of the discharge door 24 through the push plate 26.

[0048] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
