Description

Technical Field

[0001] The present invention relates to the technical field of celadon processing, in particular to a celadon blank repairing device. Background Art

[0002] Celadon is a type of porcelain with a green glaze on the surface and is a treasure of Chinese ceramic firing technology.

[0003] Celadon's hue is primarily due to the presence of a certain amount of iron oxide in the body and glaze, resulting from firing in a reducing flame atmosphere. However, some celadons, due to impure iron and insufficient reducing atmosphere, may exhibit a yellow or yellowish-brown hue. Celadon is renowned for its delicate texture, crisp, flowing lines, elegant and simple shapes, and pure, vibrant colors.

[0004] Currently in the celadon production process, the initially formed celadon blanks are of uneven thickness and have burrs, and require a trimming process, which requires a trimming device.

[0005] Traditionally, the celadon blank is trimmed by placing it on a rotating plate. As the rotating plate rotates, the trimming plate and the celadon blank come into contact, thereby generating relative movement to trim the celadon blank. However, since the trimming mechanism mostly adopts a non-adjustable structure, it cannot be adjusted according to the specifications and shape differences of the celadon blank, resulting in poor trimming effect and limited applicability of the trimming device.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0044] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0045] The present invention provides a celadon blank repairing device, which can adapt to celadon of different specifications and shapes, has wide applicability, and the repairing mechanism has higher fit with the celadon blank, thereby improving the celadon blank repairing effect.

[0046] Figures 1-9 The figure shows the structure of the first embodiment of the invention of a device for repairing celadon blanks. Figures 1-9 A celadon trimming device according to this embodiment includes a workbench 100 , a pressing mechanism 200 , a flexible cover 300 , a locking assembly 500 and a suction mechanism 400 .

[0047] The workbench 100 includes a table top 110, a base 120 supporting the table top 110, and a vertical frame 130. The table top 110 has a turntable 110a, which is used to carry the celadon H and drive the celadon H to rotate. In this embodiment, the base 120 is hollow inside and is used to install the suction mechanism 400. The vertical frame 130 is installed perpendicular to the table top 110, and has a bent portion on the top parallel to the table top 110. The bent portion is used to install the pressing mechanism 200.

[0048] The pressing mechanism 200 is installed on the top of the vertical frame 130 and can be raised and lowered to extend into the celadon bottle H placed on the turntable 110a and fix the celadon bottle H to the turntable 110a. Figure 7In this embodiment, the pressing mechanism 200 is composed of a lifting drive component 210, a carrying platform 220 and a pressing panel 240a, wherein the lifting drive component 210 is installed on the bent portion of the vertical frame 130, the carrying platform 220 is installed at the end of the lifting drive component 210 and is parallel to the table 110, the pressing rod 240 is installed at the bottom of the carrying platform 220, and the bottom of the pressing rod 240 has a pressing panel 240a parallel to the table 110. When the lifting drive component 210 is driven to descend, the pressing rod 240 follows the lifting drive. Component 210 descends, and during the descending process extends to the opening at the top of the celadon H placed on the turntable 110a and continues to move downward until the pressure panel 240a is in pressure contact with the bottom of the celadon H. At this time, due to the pressure of the pressure panel 240a, the celadon H is fixed on the turntable 110a. Preferably, the lifting drive component 210 can be an electric telescopic rod, a hydraulic telescopic rod or a pneumatic telescopic rod, and the pressure panel 240a can be supported by a rubber material to ensure soft contact with the bottom of the celadon H and avoid damage to the celadon H due to hard contact.

[0049] The top of the flexible cover 300 is mounted on the pressing mechanism 200 and can follow the pressing mechanism 200 to rise and fall to surround the celadon bottle H. Figure 8 As shown, in this embodiment, the flexible cover 300 includes a strip 310 whose top is fixed to the bottom of the supporting platform 220 and arranged in a circle, a flexible bag 320 arranged in a circle between two adjacent strips and sealed at the top, a ring 330 fixed to the bottom end of the strip 310 and connected to the bottom of the flexible bag 320, and a rotating component 340 arranged on the inner wall of each strip 310 at equal distances from top to bottom, wherein the flexible bag 320 is fan-shaped and has a frosted inner surface. In this embodiment, the strip 310 and the flexible bag 320 can be made of PVC material, which ensures both softness and toughness. In the process of the pressing mechanism 200 descending to press the celadon H, the flexible cover 300 descends together with the supporting platform 220, covering the celadon H, and at the same time the ring 330 falls onto the table 110, waiting for the locking component 500 to lock it.

[0050] The locking assembly 500 is installed on the table 110 and locks the bottom of the flexible cover 300 on the table 110 by horizontal rotation, so that the flexible cover 300, the celadon bottle H and the table 110 form a closed space.

[0051] The suction mechanism 400 is installed in the base 120 and extends into the enclosed space to continuously extract the air in the enclosed space while driving the turntable 110a to rotate. Figure 1 、 Figure 3 and Figure 9As shown, a through hole 110b is provided on the top of the table 110, which surrounds the turntable 110a and is connected to the closed space. The suction mechanism 400 includes a circular pipe 410, an air delivery pipe 420 with one end connected to the circular pipe 410 and the other end connected to the through hole 110b, an air induced draft shell 430 located at the bottom of the circular pipe 410 and connected to the inside of the circular pipe 410 at the top, an air induced draft fan blade 440 arranged inside the air induced draft shell 430, a driven wheel 450 located at the bottom of the air induced draft shell 430 and fixed coaxially with the air induced draft fan blade 440, a driving wheel 460 engaged with the driven wheel 450 and surrounded by the driven wheel 450, and a driving motor 470 installed in the hollow chamber of the base 120 and with the output end key-connected to the driving wheel 460, and fixed at the top to the bottom of the turntable 110a. In the specific blank repairing process, the driving motor 470 drives the active wheel 460 to rotate, and at the same time drives the turntable 110a to rotate. The turntable 110a mainly drives the celadon bottle H to rotate, and the active wheel 460 drives the driven wheel 450 to rotate synchronously. During the rotation of the driven wheel 450, the driven wheel 450 drives the induced draft fan blades 440 to rotate in the induced draft shell 430, and discharges the air in the induced draft shell 430 outward at a high speed, thereby generating a negative pressure inside the induced draft shell 430, and continuously discharges the air in the enclosed space outward through the return pipe 410, the air delivery pipe 420 and the through hole 110b. During the process of continuous outward discharge of the gas in the enclosed space, the strips 310 and the flexible bag 320 of the flexible cover 300 gradually gather toward the outer wall of the celadon bottle H until they fit into the outer wall of the celadon bottle H, as shown in FIG. Figure 4 As shown, at this time, the frosted surface of the flexible bag 320 is in contact with the outer wall of the celadon bottle H. During the rotation of the celadon bottle H, the frosted surface of the flexible bag 320 rubs against the outer wall of the celadon bottle H, thereby removing the burrs on the celadon bottle H and trimming the outer wall of the celadon bottle H. In the trimming process, since the flexible cover 300, the celadon bottle H and the table 110 form a closed space, the burrs and dust rubbed off the outer wall of the celadon bottle H fall onto the table 110 instead of drifting to the outside, thereby avoiding pollution to the external environment. In this embodiment, the diameter of the driving wheel 460 is greater than the diameter of the driven wheel 450, so that the rotation speed of the driven wheel 450 is greater than the rotation speed of the driving wheel 460, and then the driven wheel 450 drives the induced draft fan blades 440 to rotate at high speed in the induced draft shell 430.

[0052] like Figure 1The figure shows a schematic diagram of the present invention in a non-working state. When the present invention is working, the pressing mechanism 200 descends to press the celadon bottle H placed on the turntable 110a and fixes it on the turntable 110a. In the process of the pressing mechanism 200 descending, the flexible cover 300 follows the pressing mechanism 200 and descends to cover the celadon H. At the same time, the ring 330 descends and falls onto the table 110. The locking assembly 500 locks it, so that the flexible cover 300, the celadon bottle H and the table 110 form a closed space. When the suction mechanism 400 is started, the flexible cover 300, the celadon bottle H and the table 110 are closed. During operation, the suction mechanism 400 drives the turntable 110a to rotate and continuously discharges the gas in the enclosed space outward, making the enclosed space gradually smaller, so that the strip 310 of the flexible cover 300 and the flexible bag 320 gradually gather toward the outer wall of the celadon bottle H until the frosted surface of the flexible bag 320 fits the outer wall of the celadon bottle H. During the rotation of the celadon bottle H, the frosted surface of the flexible bag 320 rubs against the outer wall of the celadon bottle H, removing the burrs on the celadon bottle H and trimming the outer wall of the celadon bottle H. At this time, the state of the present invention is as follows: Figure 2 、 Figure 3 and Figure 4 shown.

[0053] Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The second embodiment of the invention is also shown. Figure 1 、 Figure 2 、 Figure 5 and Figure 6 On the basis of the first embodiment described above, the locking assembly 500 includes a rotary pressing component 510 provided on the table 110 and arranged in a circumferential manner, and a rotary driving component 520 for driving the rotary pressing component 510 to rotate. The rotary pressing component 510 includes a second shaft 510a provided perpendicular to the table 110 and rotating horizontally relative to the table 110, a pressing plate 510b provided perpendicular to and fixed to the second shaft 510a, and a first tooth portion 510c provided radially on the outer wall of the second shaft 510a. The rotary driving component 520 includes a driving ring 520a located in the annular groove 110c, an L-shaped supporting handle 520b provided on the outer wall of the driving ring 520a, a ball grip 520c rotatably connected to the top of the supporting handle 520b, and a second tooth portion 520d provided on the inner wall of the annular groove 110c and meshing with the first tooth portion 510c. In the unlocked state, as shown in FIG. Figure 1As shown, at this time, the angle between the rotating pressing component 510 and the rotary driving component 520 is in a relatively small state. When the ring 330 of the flexible cover 300 falls onto the table 110, the ball grip 520c is held and pushed. At this time, the driving ring 520a rotates in the ring groove 110c, and the second shaft 510a is driven to rotate by the second tooth portion 520d and the first tooth portion 510c, thereby causing the pressing plate 510b to rotate along with the second shaft 510a, pressing the ring 330 onto the table 110. The pressed state is shown in FIG. Figure 2 shown.

[0054] Figure 10 and Figure 11 The third embodiment of the invention is also shown. Figure 10 and Figure 11, different from the above embodiment, the rotating assembly 340 of the celadon trimming device of this embodiment includes a C-shaped frame 340a installed on the inner wall of the strip 310, a first shaft 340b arranged between the two ends of the C-shaped frame 340a and rotatable relative to the C-shaped frame 340a, and a ball 340c installed on the first shaft 340b, the ball 340c is elastic and hollow inside, and a plurality of pressure sensors 340d are arranged radially and equidistantly on the outer wall of the first shaft 340b, the sensing portion of the pressure sensor 340d is in contact with the inner wall of the ball 340c, and the contact point between the sensing portion of the pressure sensor 340d and the inner wall of the ball 340c is located at the maximum inner diameter of the ball 340c. On the plane, the pressure sensor 340d is electrically connected to the controller, and the controller is electrically connected to the drive motor 470. Although the current blank trimming device can trim the celadon blank, the smoothness of the outer wall of the celadon blank is generally judged by the workers based on their experience and cannot be accurately controlled, which can easily lead to excessive trimming or seemingly burr removal, but after the trimming is completed, the smoothness is not enough. For this reason, the present invention sets a rotating component 340. During the process of the celadon bottle H rotating and rubbing the frosted surface of the flexible bag 320 to trim the blank, the sphere 340c fits the outer wall of the celadon bottle H and continuously rotates synchronously with the outer wall of the celadon bottle H. During the rotation of the sphere 340c, the sphere 340c Different parts of the radial outer wall of the maximum diameter contact different parts of the outer wall of the celadon bottle H on the same plane. If there are burrs on a certain part of the celadon bottle H on the plane, while other parts are smooth and burr-free, then when the part of the celadon bottle H with the burrs contacts the sphere 340c, it will squeeze the contact part of the sphere 340c. After the squeezed part of the sphere 340c is deformed, it will exert a pressing force on the sensing part of the pressure sensor 340d that is in contact with the position. However, other parts of the celadon bottle H on the same plane that are smooth and burr-free will not squeeze the sphere 340c after contacting the sphere 340c. Therefore, the pressure sensors 340d in the sphere 340c at other parts will not be squeezed. 0d will not receive the resistance pressure, so the pressure value of the pressure sensor 340d installed in the sphere 340c will be different. If all parts of the celadon bottle H on the plane have no burrs, at this time, all the pressure sensors 340d installed in the same plane in the same sphere 340c transmit the same pressure value to the controller, indicating that the outer wall of the celadon bottle H in the plane is already in a smooth state. When the pressure values ​​transmitted by the pressure sensors 340d in each sphere 340c are equal, it means that the parts of the celadon bottle H in contact with the sphere 340c are all in a smooth state. At this time, the controller controls the drive motor 470 to stop and stop trimming the celadon bottle H to avoid excessive trimming.

[0055] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
