A hydraulic cylinder is located at the bottom of the support frame, and a rolling head is fixedly mounted at the output end of the hydraulic cylinder. A clamping structure, including a first threaded rod, is provided on the surface of the rotating plate. This invention allows workers to easily change different forming molds according to the different sizes and shapes of the ceramic handicrafts. It also allows for the installation and limiting clamping of the forming mold, preventing it from shaking during use and affecting the production of the handicrafts. Furthermore, it accelerates the forming efficiency of ceramic handicrafts and improves production efficiency.

[0004] However, after the ceramic blank is rolled and formed in this equipment, it is difficult to remove the ceramic blank from the forming mold because the mold is a whole, which in turn affects the production efficiency of the ceramic blank. Summary of the Invention

[0008] As an improvement, the spinning unit includes a spindle, a blade disposed in front of the spindle, a spindle drive unit disposed behind the spindle, a blade drive unit disposed behind the spindle drive unit and poweredly connected to the blade, and a spinning block mounted on the blade.

[0009] As an improvement, the mobile frame assembly includes a mounting bracket mounted on the frame, a sprocket drive unit disposed on the mounting bracket, and a power pair disposed on the mounting bracket and driving the sprocket drive unit to rotate.

[0010] As an improvement, the main turntable includes a hollow rotating shaft rotatably mounted on the pallet, a support tray disposed on the hollow rotating shaft, and a support plate disposed outside the hollow rotating shaft and capable of abutting against the pallet.

[0011] As an improvement, the secondary turntable includes a rotating shaft rotatably mounted inside the hollow rotating shaft and a rotating disk disposed at the top of the hollow rotating shaft and rotatably mounted above the support tray, the rotating disk being positioned above the support tray.

[0012] As an improvement, the power unit includes a bevel gear a connected to the hollow rotating shaft and sleeved outside the rotating shaft, a bevel gear b connected to the rotating shaft, a motor mounting base b disposed at the bottom of the support plate, a motor b disposed on the motor mounting base b, and a bevel gear c disposed at the power output end of the motor b and meshing with the bevel gear a and the bevel gear b.

The fixed strip can scrape the outside of the ceramic blank, thereby improving the quality of the ceramic blank. (3) In this invention, the module assembly moves with the moving frame assembly, thereby enabling the mold cavity to move between the loading and unloading station and the spinning station, which improves production safety and further improves the production efficiency of ceramic blanks.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Example: like Figure 1 As shown, a ceramic craft forming machine includes: Rack 1; Spinning assembly 2, the spinning assembly 2 includes a column 21 disposed on the frame 1, a slide table unit 22 slidably disposed on the column 21, and a spinning unit 23 disposed on the slide table unit 22; Mobile frame assembly 3, the mobile frame assembly 3 being disposed on the frame 1; and The mold assembly 4 moves with the movable frame assembly 3 and passes through the spinning unit 23. It includes a support plate 41 mounted on the movable frame assembly 3, a main turntable 42 rotatably mounted on the support plate 41 and rotatably disposed, a mold unit 43 disposed on the main turntable 42 and rotatably disposed, a secondary turntable 44 rotatably mounted at the middle position of the main turntable 42, a power unit 45 driving the main turntable 42 and the secondary turntable 44 to rotate in opposite directions, and a limiting unit 46 for controlling the opening and closing of the mold unit 43. The mold unit 43 includes several sets of circumferentially arranged side plates 431 and fixing rods 432. The side plates 431 and the fixing rods 432 are spaced apart. The side plates 431 are rotatably arranged. The several sets of side plates 431 and fixing rods 432, the main turntable 42 and the auxiliary turntable 44 form a mold cavity 40 that can be aligned with the spinning unit 23.

[0024] Furthermore, such as Figure 1As shown, the slide unit 22 includes a slider rail structure pair 221 disposed on the column 21, a slide plate 222 mounted on the slider rail structure pair 221, a lead screw pair 223 mounted on the column 21 and poweredly connected to the slide plate 222, a motor mounting base a224 disposed on the top of the column 21, and a motor a225 disposed on the motor mounting base a224 and poweredly connected to the lead screw pair 223 via a coupling.

[0025] It should be noted that the slider and slide rail structure 221 is a slider and slide rail of the HIWIN brand; the motor a225 is a servo motor of the Mitsubishi brand. The motor a225, together with the lead screw 223, can more accurately control the position of the slide plate 222 and the spinning unit 23.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, the spinning unit 23 includes a main shaft 231, a blade 232 disposed in front of the main shaft 231, a main shaft drive pair 233 disposed in rear of the main shaft 231, a blade drive pair 234 disposed in rear of the main shaft drive pair 233 and poweredly connected to the blade 232, and a spinning block 235 mounted on the blade 232.

[0027] It should be noted that when the spinning unit 23 is working, the spinning block 235 can enter the mold cavity 40 to press the ceramic slurry.

[0028] It should also be noted that the blade 232, the spindle drive unit 233, and the blade drive unit 234 are all existing technologies and will not be described in detail in this invention.

[0029] It is worth mentioning that the spinning block 235 can move radially while rotating with the spreading blade 232, thereby achieving eccentric rotation to press the ceramic slurry and improving the pressing efficiency.

[0030] Furthermore, such as Figure 1 As shown, the mobile frame assembly 3 includes a mounting frame 31 mounted on the frame 1, a sprocket drive unit 32 disposed on the mounting frame 31, and a power pair 33 disposed on the mounting frame 31 and driving the sprocket drive unit 32 to rotate.

[0031] It should be noted that the power pair 33 is a motor drive device.

[0032] It should also be noted that the sprocket drive unit 42 can transport the pallet 41. When the mold unit 43 is sent to the bottom of the spinning unit 23, the spinning unit 23 performs spinning. When the mold unit 43 leaves the bottom of the spinning unit 23, the mold cavity 40 can be loaded and unloaded. The loading and unloading operation space is increased and the process is safer after the mold unit 43 leaves the spinning unit 23.

[0033] Furthermore, such as Figure 6 As shown, the main turntable 42 includes a hollow rotating shaft 421 rotatably mounted on the pallet 41, a support tray 422 disposed on the hollow rotating shaft 421, and a support plate 423 disposed outside the hollow rotating shaft 421 and capable of abutting against the pallet 41.

[0034] Furthermore, such as Figure 6 As shown, the secondary turntable 44 includes a rotating shaft 441 rotatably installed inside the hollow rotating shaft 421 and a rotating disk 442 disposed at the top of the hollow rotating shaft 421 and rotatably installed above the support tray 422. The rotating disk 442 is positioned above the support tray 422.

[0035] It should be noted that the rotating disk 442 is positioned higher than the support tray 422, which creates a step at the bottom of the ceramic craft.

[0036] Furthermore, such as Figure 5 As shown, the power unit 45 includes a bevel gear a451 connected to the hollow rotating shaft 421 and sleeved outside the rotating shaft 441, a bevel gear b452 connected to the rotating shaft 441, a motor mounting base b453 disposed at the bottom of the support plate 41, a motor b454 disposed on the motor mounting base b453, and a bevel gear c455 disposed at the power output end of the motor b454 and meshing with the bevel gear a451 and the bevel gear b452.

[0037] It should be noted that the rotation of the motor b454 drives the bevel gear c455 to rotate, and the bevel gear c455 drives the bevel gear a451 and the bevel gear b452 to rotate. The hollow main shaft 421 and the rotating shaft 441 rotate in opposite directions. Since the ceramic blank has a large contact area with the rotating disk 442 after it is formed, the ceramic blank will rotate with the rotating disk 442.

[0038] Furthermore, the mold unit 43 also includes a mounting groove 433 formed on the support tray 422 and corresponding to the side plate 431, and a connecting plate 434 disposed at the bottom of the side plate 431 and rotatably mounted in the mounting groove 433.

[0039] It should be noted that the mounting groove 433 is designed to allow the connecting plate 434 to better drive the side plate 431 to rotate outward.

[0040] Furthermore, such as Figure 4 and Figure 7 As shown, the limiting unit 46 includes limiting rings 461 that can abut against the outer sides of several sets of side plates 431, four sets of guide rods 462 that are vertically and slidably disposed on the support plate 41 and connected to the limiting rings 461, connecting rods 463 connected to the bottom of two sets of guide rods 462, and cylinders 464 disposed at the bottom of the support plate 41 and whose power output end is poweredly connected to the connecting rods 463.

[0041] It should be noted that, as Figure 7 As shown, the cylinder 464 drives the connecting rod 463 and the guide rod 462 to move downward, which in turn drives the limiting ring 461 to move downward and disengage from the several sets of side plates 431. When the support tray 422 rotates, the side plates 431 can rotate smoothly outward under their own weight and centrifugal force, thereby opening the mold cavity 40.

[0042] It is also necessary to explain that, such as Figure 8 As shown, because there is a gap at the joint of the side plate 431 and the fixing rod 432, after the side plate 431 is flipped downward, the gap will leave a mark on the outer surface of the ceramic blank. When the ceramic blank rotates with the rotating disk 442, several sets of fixing rods 432 rotate in the opposite direction with the support tray 422, which can quickly scrape the outer side of the ceramic blank.

[0043] Furthermore, the mold assembly 4 also includes a baffle plate 47 disposed on the pallet 41 and surrounding the mold unit 43.

[0044] It should be noted that there is a rotational seal between the hollow rotating shaft 421 and the pallet 41, a rotational seal between the rotating disk 442 and the support tray 422, a sliding seal between the guide rod 462 and the pallet 41, and a seal between the baffle plate 47 and the pallet 41, so that sewage and stains will not spill out.

[0045] Work process: The cylinder 464 drives the connecting rod 463 and the guide rod 462 to move upward, which in turn drives the limiting ring 461 to move upward and causes several sets of side plates 431 to flip inward until the mold cavity 40 is formed between the several sets of side plates 431, the fixing rod 432, the main turntable 42, and the auxiliary turntable 44. The ceramic slurry is manually placed into the mold cavity 40. Then, the moving frame assembly 3 sends the mold cavity 40 to the bottom of the spinning unit 23. The spinning block 235 spins the ceramic slurry into a ceramic blank. Then, the moving frame assembly 3 takes the mold cavity 40 away from the bottom of the spinning unit 23. After that, the cylinder 464 drives the connecting rod 463 and the guide rod 462 to move upward. Rod 462 moves downward, which in turn drives the limiting ring 461 to move downward. The motor b454 rotates, driving the bevel gear c455 to rotate. The bevel gear c455 drives the bevel gear a451 and the bevel gear b452 to rotate. The hollow main shaft 421 and the rotating shaft 441 rotate in opposite directions. The side plate 431 can rotate smoothly outward under its own weight and centrifugal force, thereby opening the mold cavity 40. When the ceramic blank rotates with the rotating disk 442, several sets of fixed rods 432 rotate in the opposite direction with the support tray 422, thereby quickly scraping the outer side of the ceramic blank. Then, the worker can easily remove the ceramic blank and repeat the above production process.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
