[0020] As Figures 1-4 shown, a specific embodiment of the present utility model provides an automatic blank turning machine for a ceramic toilet, which includes a frame 1, a rotating mechanism 2, a rotating frame 3, a lifting drive mechanism 4, a first clamping assembly 5 and a second clamping assembly 6; wherein, the rotating frame 3 is connected to the frame 1 through the rotating mechanism 2, and the rotating frame 3 can be driven by the rotating mechanism 2 to turn up and down relative to the frame 1; the lifting drive mechanism 4 is arranged in the rotating frame 3, the first clamping assembly 5 and the second clamping assembly 6 are arranged in the rotating frame 3 facing each other, and the first clamping assembly 5 and the second clamping assembly 6 can be driven by the lifting drive mechanism 4 to move away from or close to each other; a conveying roller 51 is arranged on the first clamping assembly 5, and at least one of the conveying rollers 51 is a power conveying roller 511. Among them, the power conveying roller 511 can adopt an existing electric roller with a built-in drive device, or a power roller driven by an external motor and a chain commonly used in industry.

[0021] Adopting the above solution, the rotating mechanism 2 can drive the first clamping assembly 5 and the second clamping assembly 6 to turn, and cooperate with the opening and closing action of the lifting drive mechanism 4 to complete the clamping and 180-degree turning of the ceramic blank. The structure is simple and compact, the action is accurate and reliable, the manufacturing cost is low, and the occupied space is small. A conveying roller 51 is arranged on the first clamping assembly 5, and at least one of the conveying rollers 51 is a power conveying roller 511. The external tooling plate can be automatically sent into the first clamping assembly 5 through the power conveying roller 511, and the blank in the first clamping assembly 5 can also be automatically sent out to the equipment of the subsequent process through the power conveying roller 511 without an additional conveying mechanism, with high integration and comprehensive functions.

[0022] Among them, the rotation mechanism 2 includes a pedestal bearing 21, a rotation motor 22, and a speed reducer 23. The pedestal bearing 21 is provided on the frame 1, and the rotation shafts 31 symmetrically arranged on the side of the rotation frame 3 extend into the pedestal bearing 21; the rotation motor 22 is connected to the rotation shaft 31 through the speed reducer 23. Preferably, a passive wheel 24 is fixedly provided on one of the rotation shafts 31, a driving wheel 25 is connected to the output shaft of the speed reducer 23, and the driving wheel 25 meshes with the passive wheel 24.

[0023] The lifting drive mechanism 4 includes a lead screw 41, a guide rail 42, and a lifting motor 43 provided on the side columns of the rotation frame 3. The first clamping assembly 5 and the second clamping assembly 6 are both provided with sliding grooves 44 that cooperate with the guide rail 42, and lifting nuts 45 that cooperate with the lead screw 41; the lifting motor 43 is connected to the lead screw 41 and is used to drive the lead screw 41 to rotate.

[0024] The first clamping assembly 5 includes a first cantilever frame 52. The first cantilever frame 52 includes a first lifting seat 521 provided with the sliding groove 44 and the lifting nut 45, and a roller mounting frame 522 that horizontally extends from the first lifting seat 521. The conveying roller 51 is provided on the roller mounting frame 522. The second clamping assembly 6 includes a second cantilever frame 61. The second cantilever frame 61 includes a second lifting seat 611 provided with the sliding groove 44 and the lifting nut 45, and a mounting arm 612 that horizontally extends from the second lifting seat 611. Two parallel support bars 613 are provided on the mounting arm 612.

[0025] In order to fix the tooling plate on the surfaces of the support bars 613 or the roller mounting frame 522, clamping cylinders 7 are provided on both the support bars 613 and the roller mounting frame 522. The clamping cylinders 7 are provided at a certain distance from the corresponding surfaces of the support bars 613 or the roller mounting frame 522.

[0027] It should be noted that by setting the connecting plate 72, the structure of the frame 1 can be simplified, and the clamping cylinder 7 can be fixed above the corresponding supporting strip 613 or the roller mounting bracket 522 at the lowest cost. An avoidance groove 721 is provided inside the connecting plate 72, which can prevent the edge of the tooling plate from contacting the connecting plate 72, meet the use requirements of larger-sized tooling plates without increasing the coverage area of the supporting strip 613 and the roller mounting bracket 522, and achieve a balance between manufacturing cost and application range.

[0028] Preferably, the power transmission rollers 511 can be arranged at the frontmost and rearmost ends of the conveying rollers 51. The two power transmission rollers 511 at the frontmost and rearmost ends of the conveying rollers 51 can completely feed the tooling plate and the blank into or out of the turning machine, and ordinary conveying rollers 51 with lower usage costs are used in the middle rollers, which can further save costs.

[0029] The following takes the production of a toilet as an example to describe the working process of the equipment in detail:

[0030] After the toilet is blanked from the high-pressure workstation, it is transported to the buffer rack by the robotic arm. At this time, a dry tooling plate is sent to the first clamping assembly 5 through the external transmission line. The power transmission rollers 511 of the first clamping assembly 5 rotate to send the tooling plate to the predetermined position of the first clamping assembly 5, and the corresponding clamping cylinder 7 presses the tooling plate tightly on the conveying rollers 51. Then, the rotating motor 22 of the rotating mechanism 2 drives the driven wheel 24 to rotate through the driving wheel 25 of the speed reducer 23, driving the rotating frame 3 to flip 180 degrees. Then, the robotic arm places the dried blank on the buffer rack onto the second clamping assembly 6 of the turning machine. The lifting motor 43 of the lifting drive mechanism 4 drives the lead screw 41 to rotate, causing the first clamping assembly 5 and the second clamping assembly 6 to approach each other and clamp and fix the blank. Then, the rotating mechanism 2 drives the first clamping assembly 5 and the second clamping assembly 6 to rotate 180 degrees to flip the blank. Finally, the clamping cylinder 7 at the conveying rollers 51 releases the tooling plate, the lifting drive mechanism 4 drives the first clamping assembly 5 and the second clamping assembly 6 to move away from each other to open the blank, and the power transmission rollers 511 send the flipped blank out.

[0031] The above blank flipping method overcomes the dependence on multi-layer transmission lines of existing equipment, has its own function of feeding and discharging blanks, closely cooperates with the robotic arms widely used in the ceramic processing site, completes the automatic conveying and flipping work of brick blanks, and has low cost and convenient maintenance.

[0032] The above is the preferred implementation mode of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
