Description

Technical Field

[0001] The present invention relates to the technical field of purple clay teapot preparation devices, and in particular to a purple clay teapot shaping device and a working method thereof. Background Art

[0002] In the production process of purple clay teapots, the shaping of the body is the core step that determines the smoothness of the lines and the uniformity of the curvature of the body. Traditional manual shaping relies on the craftsman holding a bamboo comb or a knife, observing the position of the body on the turntable with the naked eye, manually adjusting the center of the body and gradually trimming the surface. This process has significant flaws: first, the center alignment relies entirely on manual experience, and alignment errors can easily lead to eccentricity of the body; second, the angle and position of the shaping tool are fixed, making it difficult to adapt to the curved surface requirements of different teapot shapes; third, the turntable speed and trimming force are entirely controlled by feel, resulting in poor consistency of the finished product and low production efficiency, making it difficult to meet the needs of industrial production.

[0003] In existing technology, some ceramic shaping equipment uses a rotating disk to drive the green body and is equipped with fixed shaping tools, which improves shaping efficiency to a certain extent. For example, the motor drives the turntable to rotate at a constant speed, reducing the instability of manual rotation.

[0004] However, existing equipment still has the following shortcomings: the position of the blank on the tray needs to be manually adjusted repeatedly to ensure that it is aligned with the center of the turntable, which is inefficient and prone to errors; the tool installation position is fixed and cannot be adapted to different blanks.

[0027] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1-4As shown, a shaping device for preparing purple clay teapots comprises a workbench 1, on which a shaping tray 2 is provided. The lower end of the shaping tray 2 is provided with a cross mechanism 3 for controlling the horizontal movement of the shaping tray 2. The cross mechanism 3 is fixedly mounted on a rotating disk 4, which is connected to a rotating mechanism 5 for controlling its rotation, thereby driving the shaping tray to rotate. A vertical mounting shaft 6 is also provided at the side end of the workbench 1. A first fixed frame 7 is provided on the vertical mounting shaft 6 extending toward the center of the rotating disk. A visual sensor 8 is mounted on the first fixed frame 7. The detection direction of the visual sensor 8 faces directly downward and coincides with the center of the rotating disk 4. A shaping member 9 is also mounted on the vertical mounting shaft 6. By integrating the cross mechanism into the turntable, the tray has the ability to perform a combination of rotation and translation, achieving automatic calibration of the center of the blank, breaking through the limitation of traditional equipment that relies on manual fine-tuning. The angle of the shaping member is adjusted by rotating the connecting member, and the position of the shaping member is adjusted by the mounting slot in conjunction with the connecting rod, making it suitable for purple clay teapots of different sizes.

[0030] Furthermore, the shaping member 9 is a bamboo grate or a cutting tool.

[0031] Furthermore, the vertical installation shaft 6 is sleeved with a rotating connector 10, and the rotating connector 10 is horizontally provided with a mounting groove 11 at a position deviated from the vertical installation shaft 6. A connecting rod 12 is installed in the mounting groove 11, and a shaping member 9 is installed at one end of the connecting rod 12.

[0032] Furthermore, the rotating connector 10 is provided with a first bolt hole, and the vertical mounting shaft 6 and the rotating connector 10 are fastened together by a first bolt 13 ; the mounting groove 11 is provided with a second bolt hole, and the connecting shaft 12 and the mounting groove 11 are fastened together by a second bolt 14 .

[0033] Furthermore, both ends of the installation groove 11 are open.

[0034] Furthermore, the cross mechanism 3 includes a transverse movement component and a longitudinal movement component. The transverse movement component includes a first drive member 301, a first guide rail 302, and a first movable seat 303. The first movable seat 303 is slidably connected to the first guide rail 302, and the first movable seat 303 is connected to the first drive member 301 via a screw transmission. The longitudinal movement component includes a second drive member 311, a second guide rail 312, and a second movable seat 313 installed on the first movable seat 303. The second movable seat 313 is slidably connected to the second guide rail 312, and the second movable seat 313 is connected to the second drive member 311 via a screw transmission. The shaping tray 2 is installed on the second movable seat. The X-axis and the Y-axis are perpendicular and orthogonal to form a rectangular coordinate system in the horizontal plane. The positioning of the shaping tray 2 at any point in the plane is achieved by superimposing the displacement of the two axes. The screw-nut pair converts rotational motion into linear motion, and has the characteristics of high transmission accuracy and small backlash, ensuring the accuracy of tray movement. Instead of the traditional manual adjustment of the blank position, the blank center is quickly calibrated to the geometric center of the turntable 4 through automated two-dimensional movement.

[0035] Furthermore, the first driving member 301 and the second driving member 311 are pneumatic cylinders or electric cylinders.

[0036] Furthermore, the rotating mechanism 5 includes a servo motor 51 , and a rotating shaft is provided at the lower end of the rotating disk 4 , and the rotating shaft is connected to the output shaft of the servo motor via a gear set.

[0037] Example 2

[0038] The present invention also discloses a working method of a shaping device for preparing a purple clay teapot, comprising the following steps:

[0039] S1. Blank placement and initial inspection: Place the purple clay teapot blank on the shaping tray 2, use the visual sensor 8 to capture the bottom image of the blank in real time, and calculate the deviation between the geometric center of the blank and the center of the rotating disk 4;

[0040] S2. Automatic centering adjustment: The controller drives the lateral moving component and the longitudinal moving component of the cross mechanism 3 to work together according to the deviation value, and drives the shaping tray 2 along the X-axis and Y-axis through the screw drive until the center of the blank coincides with the center of the rotating disk 4;

[0041] S3. Debugging the shaping tool: According to the desired shape of the teapot, rotate the rotating connector 10 around the vertical mounting axis 6 to adjust the angle of the connecting rod 12. Slide the connecting rod 12 in the mounting slot 11 to adjust the position of the shaping member 9 to ensure that the working contact point and contact angle with the purple clay teapot body meet the shaping process requirements. Tighten the tool with the first and second bolts 13 and 14.

[0042] S4, automated shaping operation: the servo motor 51 drives the rotating disk 4 to rotate at a set speed through the gear set, driving the blank to rotate, and the shaping member 9 trims the surface of the blank.

[0043] Furthermore, in step S4, the visual sensor 8 continuously monitors the center position of the blank. If an offset is detected, the cross mechanism 3 is driven to compensate and adjust in real time until the turntable 4 stops rotating after the shaping is completed, and the cross mechanism 3 drives the tray to automatically reset to a coaxial position with the rotating disk.

[0044] like Figure 5 As shown, the purple clay teapot is replaced with a larger one. In step S3, it is only necessary to rotate the rotating connecting member 10 by a certain angle, and then move the shaping member 9 to the rear end of the workbench through the sliding connecting rod 12, so that the shaping member can still be aligned with the purple clay teapot, which is convenient for trimming.

[0045] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
