Description

Technical Field

[0001] The present invention relates to the field of ceramic production equipment, and particularly to an automatic ceramic edge trimming machine. Background Art

[0002] During the ceramic production process, after the ceramic blank is roll-formed, in order to make the port of the blank round and smooth, the edge of the blank needs to be trimmed. The edge trimming process of the ceramic blank is usually completed by an edge trimming machine. A common automatic edge trimming machine generally includes a turntable. Several turntables for placing blanks are arranged on the periphery of the turntable. Different working positions are divided at fixed positions around the turntable, and cooperate with equipment with different functions at each working position to complete related operations such as feeding, alignment, edge trimming, and discharging. Since the alignment operation and the edge trimming operation have certain requirements for the placement position of the blank on the turntable, that is, when the turntable rotates to the alignment station and the edge trimming station, the placement position of the blank on the turntable needs to correspond one by one to the corresponding operations such as the alignment operation and the edge trimming operation, so that the alignment operation and the edge trimming operation can be carried out. In the above-mentioned edge trimming machine, since the turntable can rotate during the rotation of the turntable, the circumferential position of the turntable and the blank thereon is uncertain. Therefore, it can only trim circular blanks whose positions always remain unchanged regardless of how they rotate and are placed, and cannot trim other non-circular special-shaped blanks such as oval and square blanks. For special-shaped blanks such as oval and square, currently, an edge trimming machine with manual feeding and manual discharging is usually used for edge trimming, that is, the special-shaped blank is manually placed on the turntable, the position is adjusted, and after the edge trimming machine finishes trimming, the special-shaped blank is manually taken off the turntable again; this method of trimming special-shaped blanks has low automation, is more cumbersome in operation, has a large labor volume, and the labor cost is quite high. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic ceramic edge trimming machine.

[0004] The technical solution for achieving the object of the present invention is: a ceramic automatic edge trimming machine, including a turntable, on the periphery of which a number of turntable mechanisms are distributed. Each turntable mechanism includes a bearing seat, a rotating sleeve and a turntable assembly. The bearing seat is fixedly installed on the turntable. The rotating sleeve is vertically and rotatably installed in the bearing seat. The turntable assembly includes a rotating shaft and a turntable. The rotating shaft is movably inserted into the rotating sleeve and is key-connected to the rotating sleeve. Both ends of the rotating shaft extend out of the bearing seat and the turntable. The turntable is fixedly installed at the top end of the rotating shaft. One of the turntable assembly and the bearing seat is provided with a positioning groove, and the other is provided with a positioning member. In each turntable mechanism, the positioning member is located in the positioning groove. The turntable is successively provided with a calibration station and an edge trimming station on the rotation path of the turntable mechanism. Below the turntable at the calibration station and the edge trimming station, there is respectively a turntable rotation mechanism. Each turntable rotation mechanism includes a lifting mechanism and a transmission rotation mechanism connected to the lifting mechanism and capable of being driven by the lifting mechanism to achieve lifting. The lifting mechanism is installed on a frame. The transmission rotation mechanism includes a lifting seat, a lower rotating shaft and a rotation driving mechanism. The lifting seat is fixedly connected to the lifting mechanism. The lower rotating shaft is vertically and rotatably installed on the lifting seat. The rotation driving mechanism is in transmission connection with the lower rotating shaft. Each lower rotating shaft in the transmission rotation mechanism corresponds to a turntable mechanism one by one, and each lower rotating shaft is coaxially clamped with the rotating shaft of the corresponding turntable mechanism without relative rotation.

[0005] Further, when the bearing seat is provided with a positioning groove and the turntable assembly is provided with a positioning member, the positioning groove is opened on the surface of the bearing seat, and the positioning member is located above the turntable and horizontally arranged on the rotating shaft of the turntable assembly. In each turntable mechanism, it is possible that the positioning groove is provided on the turntable assembly and the positioning member is provided on the bearing seat; or the positioning groove is provided on the bearing seat and the bearing seat is provided on the turntable assembly. Compared with the former where the positioning groove is provided on the turntable assembly, it is more convenient to provide the positioning member on the rotating shaft of the turntable assembly in the latter. And the positioning member is usually a positioning rod.

[0006] Furthermore, a limiting cross bar is provided on the lower end of the rotating shaft of the turntable assembly in each of the turntable mechanisms, an axial hole and a limiting cross groove intersecting the axial hole are provided on the upper end of each of the lower rotating shafts in each of the turntable rotating mechanisms, the rotating shaft is coaxially inserted into the axial hole of each of the lower rotating shafts in the transmission rotating mechanism at the correction station and the edge washing station, and the limiting cross bar on the lower end of the rotating shaft is inserted into the limiting cross groove. The automatic ceramic edge washing machine of the present invention has a variety of coaxial clamping structures between each lower rotating shaft in the transmission rotation mechanism at the correction station and the edge washing station and the rotating shaft of the corresponding turntable mechanism, which can be a conventional key connection or the above-mentioned limit cross bar clamped in the limit cross groove to limit the relative rotation of the lower rotating shaft and the rotating shaft, so that the lower rotating shaft can transmit the rotating shaft under the drive of the rotation drive mechanism, and then the rotating shaft and the turntable thereon can rotate by themselves, so as to cooperate to complete the correction work and edge washing work at the correction station and the edge washing station.

[0007] Further, the lower rotating shaft comprises a lower rotating shaft body and a transmission sleeve mounted on the upper end of the lower rotating shaft body, and the shaft hole and the limit transverse groove are both provided on the transmission sleeve. The cross section of the lower rotating shaft body is usually small, and it is inconvenient to set the shaft hole and the limit transverse groove, and it is not easy to replace the shaft hole and the limit transverse groove when they are damaged. Therefore, preferably, the transmission sleeve is mounted on the lower rotating shaft body, and the shaft hole and the limit transverse groove are provided on the transmission sleeve.

[0008] Furthermore, the rotary drive mechanism is a motor, and the rotary drive mechanism is connected to the lower rotating shaft through a belt mechanism, and the belt mechanism includes a main synchronous wheel connected to the rotary drive mechanism, a slave synchronous wheel installed on the lower end of the lower rotating shaft, and a transmission belt simultaneously sleeved on the main synchronous wheel and all the slave synchronous wheels in the same turntable rotating mechanism. When working, the rotary drive mechanism of the motor rotates, and sequentially drives the main synchronous wheel, the transmission belt, all the slave synchronous wheels in the same turntable rotating mechanism, all the lower rotating shafts in the same turntable rotating mechanism, the rotating shaft connected to the lower rotating shaft, and the turntable, so that the turntable and the blank thereon can rotate, and cooperate to complete the correction work and the edge washing work at the correction station and the edge washing station. The automatic ceramic edge washing machine of the present invention simultaneously drives all the lower rotating shafts in the same turntable rotating mechanism through the same transmission belt, has high transmission efficiency, and the synchronization rate of the rotation of all the lower rotating shafts in the same turntable rotating mechanism and the turntable components driven by them is higher.

[0009] Further, the number of the lower rotating shafts in each of the turntable rotating mechanisms is several. The number of the lower rotating shafts in each of the turntable rotating mechanisms can be one, two or more. When there are multiple lower rotating shafts in each of the turntable rotating mechanisms, the green bodies on the corresponding multiple turntable assemblies rotate simultaneously, completing the calibration work and the edge washing work at the calibration station and the edge washing station, with higher working efficiency.

[0010] Further, the lifting mechanism is a cylinder. The lifting mechanism can be a structure of a motor-driven lead screw, or a cylinder, or other lifting mechanisms. In comparison, the cylinder has a large load-bearing capacity, a simple structure and convenient control.

[0011] Further, vertical guide rods are provided on the lifting seat, and guide sleeves are vertically installed on the frame. The vertical guide rods and the guide sleeves correspond to each other one by one, and the vertical guide rods are movably inserted into the corresponding guide sleeves. When the transmission rotating mechanism moves up and down under the drive of the lifting mechanism, the vertical guide rods move in the guide sleeves, and the guide sleeves limit and guide the vertical guide rods, which can make the up and down movement of the transmission rotating mechanism more stable.

[0012] Further, vacuum holes are provided on the turntable assembly. When the automatic ceramic edge washing machine of the present invention is working, continuous suction is carried out through the vacuum holes, so that the green body placed on the turntable assembly can be adsorbed on the turntable assembly, avoiding the green body on the turntable assembly from falling out of the turntable assembly due to the revolution of the turntable or its own rotation.

[0013] Further, a position calibration device and an edge washing device are provided on the side of the turntable. The position calibration device is located at the calibration station, and the edge washing device is located at the edge washing station. The position calibration device calibrates the position of the green body on the turntable assembly driven by the turntable to the calibration station; the edge washing device washes the edge of the green body on the turntable assembly driven by the turntable to the calibration station.

[0014] The automatic ceramic edge-washing machine of the present invention is provided with a limiting structure in which the positioning member cooperates with the positioning groove in each of the turntable mechanisms, so that each of the turntable mechanisms located on the turntable cannot rotate freely under the limiting structure of the positioning member and the positioning groove, thereby ensuring that during the rotation of the turntable, the relative position between each turntable mechanism and the turntable will not change, that is, ensuring that the relative position between each turntable mechanism and the turntable during the rotation of the turntable is unique and determined, thereby providing an implementable condition for subsequent alignment operations; at the same time, through the setting of the turntable rotation mechanism at the calibration station and the edge-washing station, each of the turntable mechanisms rotated to the calibration station and the edge-washing station can be lifted by the turntable rotation mechanism. After being lifted, the turntable mechanism is no longer restricted by the limiting structure composed of the positioning member and the positioning groove, and can rotate self-driven under the drive of the turntable rotation mechanism to complete the corresponding alignment and edge-washing operations. The automatic ceramic edge-washing machine of the present invention provides a ceramic blank edge-washing device with a relatively high degree of automation. It can not only wash the edges of circular blanks, but especially can also wash the edges of non-circular special-shaped blanks such as oval and square, so that the special-shaped blanks are no longer limited to manual feeding and washing. Its high degree of automation makes the operation of special-shaped blanks simpler, greatly improving the edge-washing efficiency of special-shaped blanks and at the same time greatly reducing the labor intensity of workers.

[0028] The following will make a detailed description of the preferred embodiments of the ceramic automatic edge-washing machine of the present invention with reference to the accompanying drawings:

[0029] Such as Figures 1 to 12As shown, a ceramic automatic edge washing machine includes a turntable 10, and a plurality of turntable mechanisms 1 are distributed on the periphery of the turntable 10. Each of the turntable mechanisms 1 includes a bearing seat 11, a rotating sleeve 12 and a turntable assembly 13. The bearing seat 11 passes through the turntable 10 and is fixedly installed on the turntable 10. The rotating sleeve 12 is vertically and rotatably installed in the bearing seat 11. The turntable assembly 13 includes a rotating shaft 131 and a turntable 132. The rotating shaft 131 is movably passed through the rotating sleeve 12 and is key-connected to the rotating sleeve 12. Both ends of the rotating shaft 131 extend out of the bearing seat 11. The turntable 132 is fixedly mounted on the top of the rotating shaft 131. A positioning groove 111 is provided on one of the turntable assembly 13 and the bearing seat 11, and a positioning member 133 is provided on the other. The positioning member 133 in each turntable mechanism 1 is located in the positioning groove 111. The turntable 10 is sequentially provided with a correction station 101 and a washing station 102 on the rotation path of the turntable mechanism 1. A turntable rotating mechanism 2 is respectively provided below the turntable 10 at the correction station 101 and the washing station 102. Each turntable rotating mechanism 2 includes a lifting mechanism 21, a and a transmission rotating mechanism 22 connected to the lifting mechanism 21 and driven by the lifting mechanism 21 to achieve lifting and lowering. The lifting mechanism 21 is installed on a frame 20. The transmission rotating mechanism 22 includes a lifting seat 221, a lower rotating shaft 222 and a rotating driving mechanism 223. The lifting seat 221 is fixedly connected to the lifting mechanism 21. The lower rotating shaft 222 is vertically and rotatably installed on the lifting seat 221. The rotating driving mechanism 223 is transmission-connected to the lower rotating shaft 222. The rotating mechanism 223 in the turntable rotating mechanism 2 at the correction station 101 and the edge washing station 102 is Each of the lower rotating shafts 222 of the transmission rotating mechanism 22 corresponds to a turntable mechanism 1 one by one. When the lower rotating shafts 222 of the transmission rotating mechanism 22 in the turntable rotating mechanism 2 at the correction station 101 and the edge washing station 102 lift the corresponding turntable mechanism 1, each of the lower rotating shafts 222 on the transmission rotating mechanism 22 in the turntable rotating mechanism 2 is coaxially connected with the rotating shaft 131 of the corresponding turntable mechanism 1 so as to be non-rotatable relative to each other. After being lifted, the positioning member 133 in the turntable mechanism 1 is no longer located in the positioning groove 111.

[0030] In the automatic edge-washing machine for ceramics of the present invention, a position calibration device 30 and an edge-washing device 40 are provided on the side of the turntable 10, the position calibration device 30 is located at the correction station 101, and the edge-washing device 40 is located at the edge-washing station 102. The position calibration device 30 calibrates the position of the blank on the turntable assembly 13 driven by the turntable 10 to rotate to the correction station 101; the edge-washing device 40 washes the edge of the blank on the turntable assembly 13 driven by the turntable 10 to rotate to the correction station 101.

[0031] For the automatic ceramic edge-washing machine of the present invention, the position calibration device 30 and the edge-washing device 40 are of existing structures, and the specific structures of the position calibration device 30 and the edge-washing device 40 will not be elaborated in detail in the present invention.

[0032] For the automatic ceramic edge-washing machine of the present invention, a number of turntable mechanisms 1 are distributed on the periphery of the turntable 10. In each turntable mechanism 1, the turntable assembly 13 can revolve around the turntable 10 as the rotation center under the drive of the turntable 10. During the revolution of the turntable mechanism 1 with the turntable 10, the positioning member 133 in each turntable mechanism 1 is located in the positioning groove 111.

[0033] For the automatic ceramic edge-washing machine of the present invention, in the turntable mechanism 1, the rotating sleeve 12 is vertically and rotatably installed in the bearing seat 11. The rotating shaft 131 passes through the rotating sleeve 12 movably and is key-connected to the rotating sleeve 12. The rotating shaft 131 can move up and down relative to the rotating sleeve 12 but cannot rotate relatively. The rotating shaft 131 and the rotating sleeve 12 can rotate together in the bearing seat 11.

[0034] For the automatic ceramic edge-washing machine of the present invention, in the turntable rotating mechanism 2 at the calibration station 101 and the edge-washing station 102, the transmission rotating mechanism 22 can be driven by the lifting mechanism 21 to realize lifting operation; the lower rotating shaft 222 in the transmission rotating mechanism 22 can rotate under the drive of the rotation driving mechanism 223; when the lower rotating shaft 222 rotates, since each lower rotating shaft 222 is coaxially clamped with the rotating shaft 131 of the corresponding turntable mechanism 1 and cannot rotate relatively, the rotating lower rotating shaft 222 drives the rotating shaft 131 and the turntable 132 at the upper end of the rotating shaft 131, so that the turntable 132 can rotate self.

[0035] When the automatic ceramic edge-washing machine of the present invention works, the ceramic blank is placed on the turntable 132 on the turntable 10. The ceramic blank placed on the turntable 132 rotates together with the turntable 132 under the drive of the turntable 10. The rotating ceramic blank passes through the calibration station 101 and the edge-washing station 102 in sequence. At the calibration station 101, the position calibration device 30 calibrates the blank on the turntable 132 driven by the turntable 10 to the calibration station 101; at the edge-washing station 102, the edge-washing device 40 washes the edge of the blank on the turntable 132 driven by the turntable 10 to the calibration station 101. After the edge-washing is completed and the ceramic blank is taken away from the edge-washing station 102, the washed ceramic blank can be taken out from the turntable 132.

[0036] In the automatic ceramic edge cleaning machine of the present invention, when the ceramic blank on the turntable 132 rotates with the turntable 132 to the calibration station 101 for calibration or rotates to the edge cleaning station 102 for edge cleaning, specifically, after the ceramic blank rotates in place with the turntable 132, the lifting mechanism 21 in the turntable rotation mechanism 2 below the turntable 10 drives the transmission rotation mechanism 22, causing the transmission rotation mechanism 22 to move upward. In the upwardly moving transmission rotation mechanism 22, each lower rotating shaft 222 jacks up the turntable assembly 13 in the corresponding turntable mechanism 1. After the turntable assembly 13 in the corresponding turntable mechanism 1 is jacked up, the positioning member 133 on the jacked-up turntable assembly 13 in the turntable mechanism 1 is not in the positioning groove 111, and the jacked-up turntable assembly 13 in the turntable mechanism 1 is no longer restricted by the positioning groove 111 and has the condition for self-rotation; and when each lower rotating shaft 222 jacks up the turntable assembly 13 in the corresponding turntable mechanism 1, each lower rotating shaft 222 in the transmission rotation mechanism 2 is coaxially clamped with the rotating shaft 131 of the corresponding turntable mechanism 1 in a non-rotatable manner. Then, driven by the rotation drive mechanism 223, each lower rotating shaft 222 in the transmission rotation mechanism 2, as well as the rotating shaft 131 and the turntable 132 of the corresponding turntable mechanism 1, can be driven in sequence, so that the turntable 132 and the ceramic blank thereon at the calibration station 101 and the edge cleaning station 102 rotate self with the turntable 132. During the self-rotation of the ceramic blank, the position calibration device 30 calibrates the blank on the turntable assembly 13 driven by the turntable 10 to the calibration station 101; the edge cleaning device 40 cleans the edge of the blank on the turntable assembly 13 driven by the turntable 10 to the calibration station 101.

[0037] For the ceramic automatic edge-washing machine of the present invention, due to the differences in the alignment operation and the edge-washing operation, the turntable 132 and the ceramic green body thereon located at the alignment station 101 usually rotate non-continuously with the turntable 132. Specifically, at the alignment station 101, after the turntable 132 and the ceramic green body thereon rotate to a position, they stop, and the position calibration device 30 performs an alignment operation on the stopped ceramic green body; while the turntable 132 and the ceramic green body thereon located at the edge-washing station 102 usually rotate continuously with the turntable 132. Specifically, at the edge-washing station 102, the turntable 132 and the ceramic green body thereon rotate continuously without interruption, and during the continuous rotation of the ceramic green body, the edge-washing device 40 performs an edge-washing operation on the continuously rotating ceramic green body. The non-continuous rotation of the turntable 132 at the alignment station 101 and the continuous rotation of the turntable 132 at the edge-washing station 102 can be obtained by driving and controlling the rotation driving mechanism 223 in the two turntable rotation mechanisms 2.

[0038] For the ceramic automatic edge-washing machine of the present invention, after the alignment operation at the alignment station 101 or the edge-washing operation at the edge-washing station 102 is completed, the lifting mechanism 21 in the corresponding turntable rotation mechanism 2 below the turntable 10 is driven to drive the transmission rotation mechanism 22, the corresponding turntable 132, and the ceramic green body on the turntable 132 to move downward, so that the turntable assembly 13 falls back onto the turntable 10. After the positioning member 133 in the turntable assembly 13 that has fallen back onto the turntable 10 returns to the positioning groove 111, the turntable 10 rotates again.

[0039] For the ceramic automatic edge-washing machine of the present invention, by setting a limiting structure in which the positioning member 133 cooperates with the positioning groove 111 in each turntable mechanism 1, each turntable mechanism 1 located on the turntable 10 cannot rotate randomly under the limiting structure of the positioning member 133 and the positioning groove 111, so as to ensure that during the rotation of the turntable 10, the relative position between each turntable mechanism 1 and the turntable 10 will not change, that is, to ensure that the relative position between each turntable mechanism 1 and the turntable 10 is unique and determined during the rotation of the turntable 10, thereby providing feasible conditions for the subsequent alignment operation; at the same time, through the setting of the turntable rotation mechanism 2 at the alignment station 101 and the edge-washing station 102, each turntable mechanism 1 rotated to the alignment station 101 and the edge-washing station 102 can be lifted by the turntable rotation mechanism 2. After being lifted, the turntable mechanism 1 is no longer restricted by the limiting structure composed of the positioning member 133 and the positioning groove 111, and can rotate under the drive of the turntable rotation mechanism 2 to complete the corresponding alignment and edge-washing operations.

[0040] The ceramic automatic edge trimming machine of the present invention provides a ceramic blank edge trimming device with a relatively high degree of automation. It can not only perform edge trimming on circular blanks, but especially on non-circular special-shaped blanks such as oval and square blanks, enabling special-shaped blanks to no longer be limited to manual feeding and edge trimming. Its high degree of automation makes the operation of special-shaped blanks simpler, greatly improving the edge trimming efficiency of special-shaped blanks and at the same time greatly reducing the labor intensity of workers.

[0041] In the ceramic automatic edge trimming machine of the present invention, preferably, when a positioning groove 111 is provided on the bearing seat 11 and a positioning member 133 is provided on the turntable assembly 13, the positioning groove 111 is opened on the surface of the bearing seat 11, and the positioning member 133 is located above the turntable 10 and horizontally arranged on the rotating shaft 131 of the turntable assembly 13. In each turntable mechanism 1, it can be that the positioning groove 111 is provided on the turntable assembly 13 and the positioning member 133 is provided on the bearing seat 11; or it can be that the positioning groove 111 is provided on the bearing seat 11 and the bearing seat 11 is provided on the turntable assembly 13. Compared with the former where the positioning groove 111 is provided on the turntable assembly 13, it is more convenient to set the positioning member 133 on the rotating shaft 131 of the turntable assembly 13 in the latter. And the positioning member 133 is usually a positioning rod.

[0042] In the ceramic automatic edge trimming machine of the present invention, a deep groove ball bearing 1311 is usually sleeved on the rotating shaft 131 of the turntable assembly 13 in each turntable mechanism 1. The deep groove ball bearing 1311 is located above the turntable 10 and below the turntable 132. When the turntable assembly 13 of each turntable mechanism 1 is seated on the turntable 10, the deep groove ball bearing 1311 is carried on the bearing seat 11. The deep groove ball bearing 1311 that can bear a large axial load is used as the direct load-bearing member of the turntable assembly 13, and the installation is more reliable.

[0043] The ceramic automatic edge washing machine of the present invention. Preferably, a limiting cross bar 134 is provided at the lower end of the rotating shaft 131 in each of the turntable mechanisms 1. An axial hole 224 and a limiting cross groove 225 communicating with the axial hole 224 are provided at the upper end of each lower rotating shaft 222 in each of the turntable rotating mechanisms 2. The rotating shaft 131 is coaxially inserted into the axial hole 224 of each lower rotating shaft 222 in the transmission rotating mechanism 22 at the calibration station 101 and the edge washing station 102, and the limiting cross bar 134 at the lower end of the rotating shaft 131 is inserted into the limiting cross groove 225. In the ceramic automatic edge washing machine of the present invention, there are various coaxial clamping structures between each lower rotating shaft 222 in the transmission rotating mechanism 22 at the calibration station 101 and the edge washing station 102 and the rotating shaft 131 of the corresponding turntable mechanism 1. It can be a common key connection, or it can be the above-mentioned structure that the limiting cross bar 134 is clamped in the limiting cross groove 225 to limit the relative rotation of the lower rotating shaft 222 and the rotating shaft 131, so that the lower rotating shaft 222 can drive the rotating shaft 131 under the drive of the rotation driving mechanism 223, and then the rotating shaft 131 and the turntable 132 thereon can rotate self, cooperating to complete the calibration work and the edge washing work at the calibration station 101 and the edge washing station 102.

[0044] In the ceramic automatic edge washing machine of the present invention, preferably, the lower rotating shaft 222 includes a lower rotating shaft body 2221 and a transmission sleeve 2222 installed at the upper end of the lower rotating shaft body 2221. The axial hole 224 and the limiting cross groove 225 are both provided on the transmission sleeve 2222. The cross section of the lower rotating shaft body 2221 is usually small, it is inconvenient to set the axial hole 224 and the limiting cross groove 225, and it is not easy to replace them when the axial hole 224 and the limiting cross groove 225 are damaged. Therefore, preferably, a transmission sleeve 2222 is sleeved on the lower rotating shaft body 2221, and the axial hole 224 and the limiting cross groove 225 are provided on the transmission sleeve 2222.

[0045] The ceramic automatic edge washing machine of the present invention. Preferably, the rotary drive mechanism 223 is a motor. The rotary drive mechanism 223 is in transmission connection with the lower rotating shaft 222 through a belt mechanism 226. The belt mechanism 226 includes a main synchronous pulley 2261 connected to the rotary drive mechanism 223, a slave synchronous pulley 2262 installed at the lower end of the lower rotating shaft 222, and a transmission belt 2263 sleeved on the main synchronous pulley 2261 and all the slave synchronous pulleys 2262 in the same rotary table rotating mechanism 2. During operation, the rotary drive mechanism 223, which is a motor, rotates, successively driving the main synchronous pulley 2261, the transmission belt 2263, all the slave synchronous pulleys 2262 in the same rotary table rotating mechanism 2, all the lower rotating shafts 222 in the same rotary table rotating mechanism 2, the rotating shaft 131 clamped with the lower rotating shaft 222, and the rotary table 132, so that the rotary table 132 and the green body thereon can rotate self - sufficiently, and cooperate to complete the calibration work and the edge washing work at the calibration station 101 and the edge washing station 102. In the ceramic automatic edge washing machine of the present invention, all the lower rotating shafts 222 in the same rotary table rotating mechanism 2 are simultaneously driven by the same transmission belt 2263, with high transmission efficiency, and the synchronization rate of all the lower rotating shafts 222 in the same rotary table rotating mechanism 2 and the rotary table assembly 13 driven by them is higher.

[0046] In the ceramic automatic edge washing machine of the present invention, preferably, the number of the lower rotating shafts 222 in each rotary table rotating mechanism 2 is several. The number of the lower rotating shafts 222 in each rotary table rotating mechanism 2 can be one, two or more. When there are multiple lower rotating shafts 222 in each rotary table rotating mechanism 2, the green bodies on the corresponding multiple rotary table assemblies 13 rotate simultaneously to complete the calibration work and the edge washing work at the calibration station 101 and the edge washing station 102, with higher working efficiency.

[0047] In the ceramic automatic edge washing machine of the present invention, preferably, the lifting mechanism 21 is a cylinder. The lifting mechanism 21 can be a structure of a motor - driven lead screw, or a cylinder, or other lifting mechanisms. In comparison, the cylinder has a large load - bearing capacity, a simple structure and convenient control.

[0048] In the ceramic automatic edge washing machine of the present invention, preferably, vertical guide rods 227 are provided on the lifting seat 221, and guide sleeves 228 are vertically installed on the frame 20. The vertical guide rods 227 and the guide sleeves 228 correspond to each other one by one, and the vertical guide rods 227 movably pass through the corresponding guide sleeves 228. When the transmission and rotation mechanism 22 moves up and down under the drive of the lifting mechanism 21, the vertical guide rods 227 move in the guide sleeves 228. The limit and guidance of the guide sleeves 228 to the vertical guide rods 227 can make the up - and - down movement of the transmission and rotation mechanism 22 more stable.

[0049] For the automatic ceramic edge trimming machine of the present invention, preferably, vacuum holes 135 are provided on the turntable assembly 13. Specifically, the vacuum holes 135 communicate with the bearing seat 11, the bearing seat 11 communicates with the air cavity 103 in the turntable 10 through an air pipe 136, the air cavity 103 in the turntable 10 communicates with the air chamber 105 in the turntable fixing seat 104, and the air chamber 105 is connected to an air pump through a suction pipe, as Figure 13 shown.

[0050] During the operation of the automatic ceramic edge trimming machine of the present invention, continuous suction through the vacuum holes 135 can cause the green body placed on the turntable assembly 13 to be adsorbed on the turntable assembly 13, preventing the green body on the turntable assembly 13 from falling off the turntable assembly 13 due to the revolution of the turntable 10 or its own rotation.

[0051] For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should all be regarded as falling within the protection scope of the present invention.
