Description

Technical Field

[0001] The present invention relates to the technical field of ceramic appliance production equipment, and particularly relates to a ceramic appliance edge washer. Background Art

[0002] After ceramics are pressed and fired, since the peripheries of their formed blanks are not regular enough, edge grinding equipment is usually required to polish the edges of bowls and dishes to make them smooth and round, avoid sharp burrs, and improve the use safety, aesthetics and tactile comfort of ceramic appliances.

[0003] As the ceramic edge grinder disclosed in the invention patent CN105364662B, existing ceramic edge washing equipment generally adopts a turntable form: a turntable drives a plurality of materials arranged in a circle to move on an annular path, so as to realize the continuous supply of edge washing materials. The materials are fixed by a rotating shaft with a vacuum adsorption function on the turntable and the materials are driven to rotate to cooperate with an edge washing appliance arranged beside the turntable to realize edge washing or grinding.

[0004] During the edge washing process, the coaxiality between the material and the rotating shaft has a great influence on the edge washing effect. To ensure the coaxiality between the ceramic material and the rotating shaft, the manufacturer either feeds the material through a high-precision feeding device to ensure the placement accuracy during feeding, or adds a position correction device between the feeding station and the edge washing station to trim the coaxiality between the ceramic material and the rotating shaft.

[0005] However, high-precision feeding has high requirements for the shape of the ceramic material itself, and it is difficult to ensure the dimensional accuracy of the ceramic material itself before edge washing, especially for special-shaped ceramic appliances, the difficulty of high-precision feeding is high; moreover, the versatility of this feeding device is low, and after the specifications or shapes of the materials change, the feeding device often needs to be redesigned or a large number of components need to be replaced.

[0006] In the existing ceramic edge washing equipment, the rotating shaft that drives the material to rotate self is synchronously connected through a transmission mechanism along the entire circle path and is synchronously started and stopped by a driving element. For example, a plurality of rotating shafts are synchronously rotated by driving a plurality of sprockets through an entire-circle chain. Similarly, the on-off of the negative pressure of multiple rotating shafts is also uniformly controlled by an air slip ring. This results in a high degree of consistency in the adsorption and rotation actions of each rotating shaft and low flexibility. During the position correction process, the rotating shaft needs to disconnect the negative pressure and maintain a low rotation speed, so edge washing processing cannot be carried out simultaneously, which has a great impact on the processing cycle time. Summary of the Invention

[0007] The purpose of the present invention is to provide a ceramic appliance edge washer to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0008] The technical solutions adopted to solve the above technical problems: A ceramic utensil edge washing machine, comprising: a turntable device, a calibration device and an edge washing device; The turntable device includes a revolving turntable, a revolving driving member and a plurality of rotating shaft mechanisms. The revolving turntable has a central axis extending vertically. The plurality of rotating shaft mechanisms are uniformly arranged around the central axis on the revolving turntable. The rotating shaft mechanism includes a rotating shaft and a self-rotating transmission wheel. The rotating shaft is rotatably connected to the revolving turntable, and the self-rotating transmission wheel is coaxially and fixedly connected to the rotating shaft. The revolving driving member is used to drive the revolving turntable to rotate, so that the plurality of rotating shaft mechanisms move synchronously along a first circular path; The first circular path includes a first self-rotating section, a second self-rotating section and a non-self-rotating section; the turntable device further includes two self-rotating driving members. The self-rotating driving member includes a transmission belt driven by a motor and moving along a circular path. At least one section of the transmission belts of the two self-rotating driving members are respectively in transmission engagement with the self-rotating transmission wheels in the first self-rotating section and the second self-rotating section; The calibration device and the edge washing device are respectively arranged beside the first self-rotating section and the second self-rotating section. The calibration device is provided with a rotatable centering wheel, and the edge washing device is provided with a rotatable edge washing wheel.

[0009] The ceramic utensil edge washing machine provided by the present invention has at least the following beneficial effects: The revolving driving member can drive the revolving turntable to rotate, so that the plurality of rotating shaft mechanisms move along the first circular path. When the rotating shaft mechanism moves to the first self-rotating section or the second self-rotating section, its self-rotating transmission wheel contacts the transmission belt of the corresponding self-rotating driving member to achieve transmission connection, so that the rotating shaft can rotate. The two self-rotating driving members can respectively drive the rotating shaft mechanisms in the first self-rotating section or the second self-rotating section to rotate. The rotation speeds of the rotating shaft mechanisms in the first self-rotating section and the second self-rotating section can be set according to different needs. The rotating shaft mechanism in the first self-rotating section can rotate at a lower speed to achieve centering calibration through the centering wheel, avoiding the material falling off the rotating shaft due to too high a rotation speed; while the rotating shaft mechanism in the second self-rotating section can rotate at a higher speed to perform cleaning and polishing through the edge washing wheel, improving the edge washing efficiency. The ceramic utensil edge washing machine of the present invention sets the rotation speeds of the rotating shaft mechanisms at different positions in a partitioned manner, so that the rotation speeds of the rotating shaft mechanisms during the centering calibration process and the edge washing process can be inconsistent, reducing the feeding difficulty while maintaining the edge washing processing efficiency.

[0023] In the description of the present invention, if there are descriptions with words such as "several", its meaning is one or more, and the meaning of multiple is more than two. Understandings such as greater than, less than, exceeding, etc. do not include the present number, and understandings such as above, below, within, etc. include the present number.

[0024] In the description of the present invention, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0025] Refer toFigures 1 to 9 , the following embodiments are made for the ceramic ware edge washing machine of the present invention: A ceramic ware edge washing machine, comprising: a turntable device 100, a calibration device 200 and an edge washing device 400.

[0026] The turntable device 100 includes: a revolving turntable 110, a revolving driving member 120, a rotating shaft mechanism 130 and two self-rotating driving members 140.

[0027] The revolving turntable 110 is in a disc shape, and the revolving turntable 110 has a central axis extending vertically. The revolving driving member 120 has a revolving driving end that is in transmission connection with the revolving turntable 110 and makes the revolving turntable 110 rotate around its own central axis.

[0028] The number of the rotating shaft mechanisms 130 is multiple. The multiple rotating shaft mechanisms 130 are uniformly arranged around the central axis on the revolving turntable 110. The rotating shaft mechanism 130 includes: a rotating shaft 131 and a self-rotating transmission wheel 132. The rotating shaft 131 is in a cylindrical shape extending vertically, and the rotating shaft 131 is rotatably connected to the revolving turntable 110 around its own axis. The self-rotating transmission wheel 132 is coaxially and fixedly connected to the rotating shaft 131.

[0029] When the revolving driving member 120 drives the revolving turntable 110 to rotate, the multiple rotating shaft mechanisms 130 move synchronously along a first circular path. The first circular path includes a first self-rotating section, a second self-rotating section and a non-rotating section.

[0030] The self-rotating driving member 140 is provided with a transmission belt 145 that is driven by a motor and moves along a circulating path. At least one section of the transmission end of one of the self-rotating driving members 140 is in transmission engagement with the self-rotating transmission wheel 132 in the first self-rotating section to drive the rotating shaft 131 in the first self-rotating section to rotate. At least one section of the transmission end of the other self-rotating driving member 140 is in transmission engagement with the self-rotating transmission wheel 132 in the second self-rotating section to drive the rotating shaft 131 in the second self-rotating section to rotate.

[0031] The calibration device 200 is provided with a rotatable alignment pulley 210, and the calibration device 200 is arranged beside the first self-rotating section; the edge washing device 400 is provided with a rotatable edge washing wheel 410, and the edge washing device 400 is arranged beside the second self-rotating section.

[0032] During actual use, the revolution driving member 120 drives the revolution turntable 110 to rotate, so that the plurality of rotating shaft mechanisms 130 move along a first annular path. When the rotating shaft mechanism 130 moves to the first self-rotation section or the second self-rotation section, its self-rotation transmission wheel 132 contacts the transmission belt 145 of the corresponding self-rotation driving member 140 to achieve a transmission connection, so that the rotating shaft 131 can rotate. The two self-rotation driving members 140 can respectively drive the rotating shaft mechanisms 130 in the first self-rotation section or the second self-rotation section to rotate. The rotation speeds of the rotating shaft mechanisms 130 in the first self-rotation section and the second self-rotation section can be set according to different needs respectively. The rotating shaft mechanism 130 in the first self-rotation section can rotate at a lower speed to achieve centering correction through the centering transfer wheel 210 and prevent the material from falling off the rotating shaft due to too high a rotation speed; while the rotating shaft mechanism 130 in the second self-rotation section can rotate at a higher speed to perform cleaning and grinding through the edge cleaning wheel 410, improving the edge cleaning efficiency. The edge cleaning machine for ceramic utensils of the present invention sets the rotation speeds of the rotating shaft mechanisms 130 at different positions in a partitioned manner, so that the rotation speeds of the rotating shaft mechanisms 130 during the centering correction process and the edge cleaning process can be inconsistent, reducing the feeding difficulty while maintaining the edge cleaning processing efficiency.

[0033] In this embodiment, the edge cleaning machine for ceramic utensils further includes a shaping device 300, and the shaping device 300 is used for grooving and / or trimming and shaping the ceramic material. The shaping device 300 is arranged beside the first self-rotation section, and the correction device 200 and the shaping device 300 are arranged in sequence along the circumferential direction of the revolution turntable 110. Specifically, when observing in the direction from top to bottom, the revolution turntable 110 rotates in the counterclockwise direction. Refer to the attached Figure 2 , the correction device 200, the shaping device 300 and the edge cleaning device 400 are arranged in sequence along the counterclockwise direction on the outside of the revolution turntable 110.

[0034] The shaping device 300 includes a shaping member 310 and a shaping driving member 320, and the shaping driving member 320 is used to drive the shaping member 310 to approach or move away from the central axis of the revolution turntable 110. The shaping member 310 in this embodiment includes a grooving knife 311 and a trimming knife 312. During actual use, the connection position between the main body of the ceramic utensil and the bottom foot is processed by the grooving knife 311; the edge of the ceramic utensil is trimmed by the trimming knife 312.

[0035] The shaping device 300 includes a shaping table 330, and the grooving knife 311 and the trimming knife 312 are both adjustably mounted on the shaping table 330. The adjustable structures of the grooving knife 311 and the trimming knife 312 can refer to existing adjustable structures, such as bolts, top screws, slides or linear guides to achieve position adjustment in the linear direction, or adopt rotary joints, arc grooves or universal joints to achieve angle adjustment, or realize adjustable connection through modular standard parts such as threaded columns, telescopic sleeves, rotary joints, micro-slides, etc.

[0036] The shaping drive component 320 is used to drive the shaping table 330 to move relative to the revolving turntable 110, and the shaping drive component 320 includes: a transverse drive component 321 and a longitudinal drive component 322, the transverse drive component 321 is used to drive the shaping table 330 to move along a first direction toward the center of the revolving turntable 110, and the longitudinal drive component 322 is used to drive the shaping table 330 to move along a second direction perpendicular to the first direction.

[0037] Specifically, the shaping device 300 includes a fixed shaping frame, and a connecting plate 340 is provided between the shaping platform 330 and the shaping frame.

[0038] The transverse drive assembly 321 includes a transverse drive motor and a transverse drive member. The connecting plate 340 is slidably connected to the shaping frame along the first direction, and the two ends of the transverse drive member are respectively rotatably hinged to the shaping frame and the connecting plate 340. The output shaft of the transverse drive motor is in transmission connection with the transverse drive member, so that the transverse drive member rotates relative to the shaping frame, and the connecting plate 340 moves relative to the shaping frame along the first direction.

[0039] Similarly, the longitudinal drive assembly 322 includes a longitudinal drive motor and a longitudinal drive member. The shaping table 330 is slidably connected with the connecting plate 340 along the second direction, and the two ends of the longitudinal drive member on opposite sides are respectively rotatably hinged with the connecting plate 340 and the shaping table 330. The output shaft of the longitudinal drive motor is in transmission connection with the longitudinal drive member, so that the transverse drive member rotates relative to the connecting plate 340, and the shaping table 330 moves relative to the connecting plate 340 along the second direction.

[0040] The transverse drive assembly 321 and the longitudinal drive assembly 322 of this embodiment both adopt an eccentric swing arm drive structure, which is simple and compact. The movement range can be adjusted by adjusting the eccentricity, that is, the size of the transverse drive member and the longitudinal drive member. Figure 8 and 9 The transverse driving assembly 321 is arranged below the connecting plate 340 , and the longitudinal driving assembly 322 is arranged below the shaping table 330 , which greatly reduces the occupied space of the shaping device 300 .

[0041] The transverse drive assembly 321 and the longitudinal drive assembly 322 can drive the shaping table 330 to move in a first direction and a second direction perpendicular to each other respectively. The transverse drive assembly 321 and the longitudinal drive assembly 322 cooperate to act synchronously, so that the grooving tool 311 and the trimming tool 312 can approach the ceramic ware along a curved path, avoiding over-cutting.

[0042] In a further embodiment, the trimming tool 312 is elastically swingably arranged. One end of the trimming tool 312 is provided with a steel wire for trimming. The other end of the trimming tool 312 is rotatably arranged and elastically arranged by a torsion spring or a spring. During actual use, the shaping drive member 320 drives the shaping table 330 to move, so that the steel wire of the trimming tool 312 elastically abuts against the edge of the ceramic ware. The elastic arrangement of the trimming tool 312 can ensure that the abutting pressure of the steel wire is not too large, thus avoiding over-trimming.

[0043] The calibration device 200 of this embodiment includes a calibration slide table 220 and a calibration feed drive unit 230. The alignment idler wheel 210 is adjustably arranged on the calibration slide table 220. The calibration feed drive unit 230 is used to drive the calibration slide table 220 to approach or move away from the central axis of the revolving turntable 110. The edge cleaning device 400 includes an edge cleaning slide table 420 and an edge cleaning feed drive unit 430. The edge cleaning wheel 410 is adjustably arranged on the edge cleaning slide table 420. The edge cleaning feed drive unit 430 is used to drive the edge cleaning slide table 420 to approach or move away from the central axis of the revolving turntable 110.

[0044] The adjustable mounting structures of the alignment idler wheel 210 and the edge cleaning wheel 410 can refer to the adjustable structures of the grooving tool 311 and the trimming tool 312, or refer to existing adjustable structures, and no examples are given here. Considering facilitating the control of the rotation speed and accuracy, the alignment idler wheel 210 and the edge cleaning wheel 410 in this embodiment are both driven by servo motors to achieve rotation. The calibration feed drive unit 230 and the edge cleaning feed drive unit 430 can adopt linear drive members such as cylinders, electric push rods, hydraulic push rods or screw-nut drive assemblies. When the calibration feed drive unit 230 drives the calibration slide table 220 to approach the revolving turntable 110, the ceramic ware can be centered and positioned by the rotating alignment idler wheel 210. When the edge cleaning feed drive unit 430 drives the edge cleaning slide table 420 to approach the revolving turntable 110, the grooving line or the mold closing line of the ceramic ware can be cleaned and polished by the edge cleaning wheel 410.

[0045] In this embodiment, the edge-washing wheel 410 is made of sponge material. The edge-washing slide 420 is further provided with a pressing wheel 440, and the pressing wheel 440 presses against one side of the edge-washing wheel 410 away from the revolving turntable 110. When the edge-washing wheel 410 rotates, the side close to the revolving turntable 110 can perform edge-washing processing on the ceramic ware. When the edge-washing wheel 410 with muddy water rotates to the side away from the revolving turntable 110, it can be extruded by the pressing wheel 440 to squeeze out the muddy water.

[0046] In this embodiment, the rotating shaft 131 rotatably penetrates through the revolving turntable 110, and the upper and lower ends of the rotating shaft 131 are respectively arranged on the upper and lower sides of the revolving turntable 110. The upper end of the rotating shaft 131 supports and holds the material, and the self-rotating transmission wheel 132 is coaxially and fixedly arranged at the lower end of the rotating shaft 131.

[0047] To prevent the material from shifting under force during processing, the rotating shaft mechanism 130 needs to fix the material thereon. An adsorbing member 133 for adsorbing the material is provided at the upper end of the rotating shaft 131. A gas guide bushing 134 is provided on the lower side of the revolving turntable 110. The gas guide bushing 134 is in a cylindrical shape, and the gas guide bushing 134 is coaxially sleeved on the rotating shaft 131 one by one to form an annular gas guide space outside the rotating shaft 131.

[0048] The upper end of the gas guide bushing 134 is fixedly and sealingly connected to the revolving turntable 110, and the lower end of the gas guide bushing 134 is rotatably and sealingly connected to the rotating shaft 131, so that the upper and lower ends of the gas guide space are sealed and airtight. The side surface of the gas guide bushing 134 is provided with a gas guide port, the gas guide port extends radially, one end of the gas guide port communicates with the gas guide space, and the other end is connected to a negative pressure generating element.

[0049] A gas guide channel communicating the adsorbing member 133 and the gas guide space is provided in the rotating shaft 131. The gas guide channel includes a first channel and a second channel that are interconnected. The first channel extends along the axial direction of the rotating shaft 131, the upper end of the first channel is connected to the adsorbing member 133, the lower end of the first channel is connected to the second channel, the second channel extends radially, and the second channel communicates the first channel and the gas guide space.

[0050] In this embodiment, a ring-shaped supporting platform 135 is provided at the upper end of the rotating shaft 131. An annular sealing ring is provided on the upper side of the supporting platform 135. The adsorbing member 133 is disposed in the middle space of the supporting platform 135. The adsorbing member 133 is an upwardly disposed vacuum suction cup having a bellows structure. In the non-adsorbing state, the upper end of the adsorbing member 133 is higher than the annular sealing ring. In the adsorbing state, the adsorbing member 133 contracts and deforms, and its upper end moves downward to press the adsorbing surface of the material tightly against the annular sealing ring.

[0051] To adapt to different ceramic ware products, the supporting platform 135 is detachably mounted on the upper end of the rotating shaft 131. When changing the product model or specification, different supporting platforms 135 and adsorbing members 133 can be replaced according to the size of the adsorbing surface of the ceramic ware, so as to improve the product matching degree and avoid the situation of product dropping.

[0052] During actual use, when the rotating shaft 131 rotates, the adsorbing member 133 is always in communication with the negative pressure space through the air guide channel. The negative pressure generated by the negative pressure generating element can be transmitted to the adsorbing member 133 through the negative pressure space and the air guide channel, so as to adsorb and fix the material at the upper end of the rotating shaft 131.

[0053] During the centering and correction process, the rotating shaft 131 needs to release the vacuum adsorption to loosen the ceramic ware product thereon. And during the edge washing process, the ceramic product needs to be adsorbed and fixed. In some other embodiments, the revolution turntable 110 adopts a central rotation structure with a fixed central axis and a rotating outer disk. Each of the rotating shaft mechanisms 130 realizes the on-off control of the negative pressure through corresponding control elements, such as solenoid valves, mechanical valves, regulating valves, etc.

[0054] To avoid the complex layout of the air pipes and control lines, in this embodiment, the revolution turntable 110 is provided with a gas distribution mechanism 150. The gas distribution mechanism 150 is disposed on the lower side of the revolution turntable 110. The gas distribution mechanism 150 includes: a gas distribution fixed disk 152 and a gas distribution rotating disk 151. The gas distribution fixed disk 152 and the gas distribution rotating disk 151 are both coaxially disposed with the revolution turntable 110. The gas distribution rotating disk 151 and the gas distribution fixed disk 152 are arranged vertically, and the gas distribution rotating disk 151 is disposed above the gas distribution fixed disk 152.

[0055] The gas distribution rotating disk 151 is provided with a plurality of gas distribution channels 1512, and the number of the gas distribution channels 1512 is the same as the number of the rotating shaft mechanisms 130. The gas distribution channels 1512 have a first port 1511 and a second port 1513. The first ports 1511 of the plurality of gas distribution channels 1512 are in one-to-one correspondence and communicate with the air guide ports. The plurality of first ports 1511 are evenly distributed on the side surface of the gas distribution rotating disk 151, and the second ports 1513 are evenly distributed in the circumferential direction on the lower side surface of the gas distribution rotating disk 151. When the revolution rotating disk 110 rotates, the gas distribution rotating disk 151 rotates synchronously, and the plurality of second ports 1513 move synchronously along the second annular path.

[0056] The upper side surface of the gas distribution rotating disk 151 is fixedly connected to the lower side surface of the revolution rotating disk 110, and the upper end surface of the gas distribution fixed disk 152 is hermetically abutted against the lower end surface of the gas distribution rotating disk 151. The upper end surface of the gas distribution fixed disk 152 is provided with a gas distribution groove 1521 and a gas leakage groove 1522. Both the gas distribution groove 1521 and the gas leakage groove 1522 extend in an arc shape and are vertically aligned with a section of the second annular path. The second port 1513 can communicate with the gas distribution groove 1521 or the gas leakage groove 1522 during the rotation process.

[0057] The gas distribution groove 1521 is communicated with the negative pressure generating element, and the gas leakage groove 1522 is communicated with the outside atmosphere. The radian angles of the gas distribution groove 1521 and the gas leakage groove 1522 are set according to requirements so that the rotating shaft mechanism 130 at the corresponding position can achieve adsorption or release. When the second port 1513 rotates into the upper side of the gas distribution groove 1521 and communicates, the adsorbing member 133 of the rotating shaft mechanism 130 corresponding to it is communicated with the negative pressure generating element through the gas distribution groove 1521 to adsorb the material. When the second port 1513 rotates into the upper side of the gas leakage groove 1522 and communicates, the rotating shaft mechanism 130 corresponding to it is communicated with the normal atmospheric pressure to release the negative pressure adsorption.

[0058] In this embodiment, the turntable device 100 includes a base frame, and the revolution rotating disk 110 and the gas distribution rotating disk 151 are rotationally connected to the base frame. The base frame of this embodiment is a frame structure welded by square tubes. Specifically, the gas distribution rotating disk 151 is in a disk shape, the upper side of the gas distribution rotating disk 151 is coaxially and fixedly connected to the revolution rotating disk 110, and a central shaft is coaxially and fixedly arranged on the lower side of the gas distribution rotating disk 151. The base frame is provided with a bearing seat rotationally connected to the central shaft. The gas distribution fixed disk 152 is in a circular ring shape, and an avoidance hole is provided in the middle of the gas distribution fixed disk 152, and the central shaft coaxially and movably passes through the avoidance hole.

[0059] The air distribution fixed disk 152 is elastically connected to the base frame in the vertical direction, so that the upper end surface of the air distribution fixed disk 152 abuts against the lower end surface of the air distribution rotating disk 151. Specifically, a plurality of guide holes are evenly provided at the lower end of the air distribution fixed disk 152, and guide posts are fixedly provided on the base frame, and the guide posts extend in the vertical direction. The guide posts correspond to the guide holes one by one, the upper ends of the guide posts are embedded in the guide holes, and springs are sleeved outside the guide posts, and the upper and lower ends of the springs are elastically abutted against the air distribution fixed disk 152 and the base frame respectively, so that the air distribution fixed disk 152 abuts upward against the air distribution rotating disk 151.

[0060] In a further embodiment, a pre-ventilation groove 1523 is provided between the end of the air distribution groove 1521 and the end of the air leakage groove 1522. Specifically, when viewed from top to bottom, both the air distribution groove 1521 and the air leakage groove 1522 extend counterclockwise along the second annular path, and the pre-ventilation groove 1523 is provided between the head end of the air distribution groove 1521 and the tail end of the air leakage groove 1522, and between the tail end of the air distribution groove 1521 and the head end of the air leakage groove 1522, and the two pre-ventilation grooves 1523 are communicated with each other as annular air grooves.

[0061] During the process that the second port 1513 corresponding to one of the rotating shaft mechanisms 130 rotates from the air distribution groove 1521 to the air leakage groove 1522, the second port 1513 corresponding to the other rotating shaft mechanism 130 rotates from the air leakage groove 1522 to the air distribution groove 1521. Among the above two rotating shaft mechanisms 130, one needs to be converted from normal pressure to negative pressure, and the other needs to be converted from negative pressure to normal pressure. When the above two second ports 1513 are respectively communicated with the two pre-ventilation grooves 1523, the suction accessories 133 of the two rotating shaft mechanisms 130 are communicated to make the air pressure average to a "slight negative pressure" state, realizing the pre-release before one rotating shaft mechanism 130 rotates to the non-self-rotating section, and the pre-suction of the other rotating shaft mechanism 130 rotating to the first self-rotating section, thereby reducing the negative pressure demand, saving energy, and making the suction and release actions more stable.

[0062] Further, the air distribution groove 1521 includes a weak adsorption groove and a strong adsorption groove, the weak adsorption groove and the strong adsorption groove are not communicated with each other, and the weak adsorption groove and the strong adsorption groove are respectively communicated with different negative pressure generating elements. During actual use, the radian angles and negative pressure intensities of the weak adsorption groove and the strong adsorption groove can be set according to needs, so as to improve flexibility.

[0063] In this embodiment, the radian angle and position of the weak adsorption groove match those of the correction device 200, and the radian angle and position of the strong adsorption groove match those of the shaping device 300 and the edge washing device 400. During the correction process, the adsorbing member 133 is connected to the weak adsorption groove, and the ceramic utensil is adsorbed by a relatively weak negative pressure, which neither affects the centering correction nor easily causes the ceramic utensil to fall off. During the shaping and edge washing processes, the adsorbing member 133 is connected to the strong adsorption groove, and the ceramic utensil is adsorbed and fixed by a relatively strong negative pressure to avoid deflection.

[0064] In this embodiment, the self-rotation driving member 140 includes: a self-rotation driving unit 141, a driving pulley 142, a driven pulley 143, a tension pulley 144, and the transmission belt 145. The self-rotation driving unit 141 is drivingly connected to the driving pulley 142, and the transmission belt 145 is wound around the driving pulley 142, the driven pulley 143, and the tension pulley 144 in a transmission manner. The driving pulley 142, the driven pulley 143, and the tension pulley 144 are all disposed on the side of the first annular path away from the center of the circle.

[0065] Considering the convenience of controlling the rotation speed and accuracy, the self-rotation driving unit 141 in this embodiment adopts a servo motor. When the self-rotation driving unit 141 drives the driving pulley 142 to rotate, the transmission belt 145 moves cyclically, so that the self-rotation transmission wheel 132 of the contact shaft mechanism 130 rotates.

[0066] In this embodiment, the correction device 200 and the shaping device 300 are disposed beside the first self-rotation section, and the edge washing device 400 is disposed beside the second self-rotation section.

[0067] In this embodiment, the correction device 200, the shaping device 300, and the edge washing device 400 all adopt a double-station structure. The correction device 200 is provided with paired centering rollers 210, the grooving knives 311 and trimming knives 312 of the shaping device 300 are both paired, and the edge washing wheels 410 of the edge washing device 400 are paired. The revolution turntable 110 is evenly distributed with twelve working stations, and the working stations include two loading stations, two correction stations, two shaping stations, two edge washing stations, two unloading stations, and two spare stations. The correction device 200 is disposed beside the two correction stations, the shaping device 300 is disposed beside the two shaping stations, and the edge washing device 400 is disposed beside the two edge washing stations.

[0068] Two loading stations, two calibration stations, two shaping stations, two edge washing stations, two unloading stations and two spare stations are evenly distributed on the edge of the revolving turntable 110 in sequence. The number of the rotating shaft mechanisms 130 is twelve, and the revolving driving member 120 drives the revolving turntable 110 to rotate 60 degrees each time, so that two adjacent rotating shaft mechanisms 130 can be moved to match with each device in sequence.

[0069] Two calibration stations and two shaping stations are within the range of the first self-rotating section, two edge washing stations are within the range of the second self-rotating section, and two spare stations, two unloading stations and two loading stations are all within the range of the non-self-rotating section.

[0070] When actually using the ceramic ware edge washing machine of the present invention to process ceramic bowls and dishes: First, two ceramic bowls and dishes are respectively loaded onto the rotating shaft mechanisms 130 of the two loading stations.

[0071] Then, the revolving driving member 120 drives the revolving turntable 110 to rotate 60 degrees around its central axis, and the two ceramic bowls and dishes are rotated from the loading stations to the calibration stations. During this process, the self-rotating transmission wheels 132 at the lower ends of the two rotating shaft mechanisms 130 both enter the first self-rotating section and are in transmission connection with the transmission belt 145 of the self-rotating driving member 140. Moreover, the second ports 1513 communicated with the two rotating shaft mechanisms 130 rotate to be communicated with the weak adsorption grooves, so that the two ceramic bowls and dishes can be slightly adsorbed and rotated at a low speed at the calibration stations. At this time, the calibration feeding driving unit 230 drives the calibration slide 220 to feed, so that the rotating centering wheel 210 contacts with the ceramic bowl and dish to improve the coaxiality with the rotating shaft 131.

[0072] Then, the revolving turntable 110 rotates 60 degrees again, and the two ceramic bowls and dishes are rotated from the calibration stations to the shaping stations. The self-rotating transmission wheels 132 at the lower ends of the two rotating shaft mechanisms 130 move from the first half section of the first self-rotating section to the second half section of the first self-rotating section, and are still in transmission connection with the transmission belt 145 of the same self-rotating driving member 140. And the second ports 1513 communicated with the two rotating shaft mechanisms 130 rotate to be communicated with the strong adsorption grooves, so that the two ceramic bowls and dishes can be firmly adsorbed and rotated at a low speed at the shaping stations. At this time, the shaping driving member 320 drives the shaping table 330 to move, so that the grooving knife 311 and the edge trimming knife 312 can contact with the ceramic bowl and dish to realize grooving processing and edge trimming processing.

[0073] Next, the revolution turntable 110 rotates 60 degrees again, and the two ceramic bowls and dishes are rotated from the shaping station to the edge washing station. The self-rotation drive wheels 132 at the lower ends of the two rotating shaft mechanisms 130 are transferred from the first self-rotation section to the second self-rotation section and are drivingly connected to the transmission belt 145 of another self-rotation drive member 140, while the second ports 1513 communicated with the two rotating shaft mechanisms 130 are still communicated with the strong adsorption groove, so that the two ceramic bowls and dishes can be firmly adsorbed and rotated at high speed at the shaping station. At this time, the edge washing feed drive unit 430 drives the edge washing slide 420 to feed, so that the rotating edge washing wheel 410 performs edge washing processing on the ceramic bowls and dishes.

[0074] After that, the revolution turntable 110 rotates 60 degrees again, and the two ceramic bowls and dishes are rotated from the edge washing station to the blanking station. The self-rotation drive wheels 132 at the lower ends of the two rotating shaft mechanisms 130 are rotated from the second self-rotation section to the non-self-rotation section, and the second ports 1513 communicated with the two rotating shaft mechanisms 130 are rotated to be communicated with the air release groove 1522, so that the two ceramic bowls and dishes are not adsorbed and do not rotate at the blanking station, which is convenient for unloading.

[0075] In some embodiments, the two spare stations can be used to clean the rotating shaft mechanism 130 to avoid affecting the placement and processing of ceramic materials. In some other embodiments, the two spare stations can be arranged between the blanking station and the edge washing station, and the ceramic ware products after edge washing are detected at the spare station, and the self-rotation drive member 140 and the air distribution groove 1521 are set to be matched.
