Description

Technical Field

[0001] The invention relates to the field of ceramic production equipment, in particular to a special-shaped ceramic production line. Background Art

[0002] The ceramic production process usually includes molding, trimming, drying, edge washing and other processes. Among them:

[0003] The trimming process is to scrape off the excess clay at the end of the roll-formed ceramic body to make the end of the roll-formed body flat. In order to trim the end of the body, a scraper is generally installed in the ceramic roll-forming machine. During the process of rolling the body, the scraper on the ceramic roll-forming machine will scrape off the excess clay at the end of the rotating body. For conventional shapes such as round bodies, their ends are usually round. Due to the regular shape of the round body, the excess clay can be scraped off at one time when it is rotated on the ceramic roll-forming machine. When an oval, square or other special-shaped body is rotated and formed on a ceramic rolling forming machine, in order to ensure that the scraper on the ceramic rolling forming machine does not hinder the rotation of the ceramic rolling forming machine mold and the ceramic rolling forming machine can operate normally, the scraper on the ceramic rolling forming machine can only extend to the rotation path of the part with a larger width of the body to scrape off the excess mud at the part with a larger width of the body, and the excess mud at other parts of the body cannot be scraped off. In other words, an oval, square or other special-shaped body cannot be trimmed completely at one time on a ceramic rolling forming machine. After the body is roll-formed, it is usually necessary to perform secondary trimming in the subsequent process, or it is not trimmed on the ceramic rolling forming machine directly, and the rolling forming and trimming operations are completed separately. That is, for an oval, square or other special-shaped body, whether it is trimmed on a ceramic rolling forming machine or not, a trimming operation is required in the subsequent process. However, due to the shape of oval, square or other special-shaped blanks, as mentioned above, the trimming method of circular blanks cannot be used to trim the blanks completely. Currently, they can only be trimmed manually, which is cumbersome, labor-intensive, and has high labor costs. In addition, the instability of manual operation often makes it impossible to guarantee the quality of trimming of special-shaped blanks.

[0004] The edge washing process is to polish the port of the green body to make the port of the green body round and smooth. The edge washing process of the ceramic green body is usually completed by an edge washing machine. An ordinary automatic edge washing machine generally includes a turntable. Several turntables for placing green bodies are arranged on the periphery of the turntable. Different working positions are divided at fixed positions around the turntable, and cooperating with equipment with different functions at each working position, related operations such as feeding, alignment, edge washing, and discharging are completed. Since the alignment operation and the edge washing operation have certain requirements for the placement position of the green body on the turntable, that is, when the turntable rotates to the alignment working position and the edge washing working position, the placement position of the green body on the turntable needs to correspond one by one to the corresponding operations such as the alignment operation and the edge washing operation, then the alignment operation and the edge washing operation can be carried out. In the above-mentioned edge washing machine, during the process of the turntable rotating with the turntable, since it can rotate, the circumferential position of the turntable and the green body on it is uncertain. Therefore, it can only carry out edge washing work on circular green bodies whose positions always remain unchanged no matter how they rotate and are placed, and cannot carry out edge washing on other non-circular special-shaped green bodies such as oval and square green bodies. For special-shaped green bodies such as oval and square, currently, usually only an edge washing machine with manual feeding and manual discharging can be used for edge washing, that is, manually place the special-shaped green body on the turntable, adjust the position, and after the edge washing machine finishes edge washing, manually take the special-shaped green body off the turntable; this way of washing the special-shaped green body has low automation, cumbersome operation, large labor intensity, and relatively high labor cost.

[0005] It can be seen from the above that the production lines of circular ceramics and non-circular special-shaped ceramics such as oval and square are not only different in the rolling dies in the rolling forming machine. In production, it is not possible to directly use the rolling die of the rolling forming machine in the circular ceramic production line to produce non-circular special-shaped ceramics such as oval and square after simply replacing the rolling die. As the mainstream shape of ceramics, circular ceramics have a huge market flow; the production technology of circular ceramics is relatively simple and mature, and basically all the existing ceramic production lines on the market are circular ceramic production lines. Due to technical difficulties in the production of special-shaped ceramics, a highly automated production line cannot be formed at present. A large number of workers are often required in its production to complete work such as trimming and edge washing, with low work efficiency and high production cost. Summary of the Invention

[0006] The purpose of the present invention is to provide a production line for special-shaped ceramics.

[0007] The technical solution for achieving the object of the present invention is: a special-shaped ceramic production line, including a side washing device. The side washing device includes a turntable, and a number of turntable mechanisms are distributed on the periphery of the turntable. 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. On the rotation path of the turntable mechanism, the turntable is sequentially provided with a calibration station and a side washing station. Below the turntable at the calibration station and the side washing station, there is a turntable rotation mechanism respectively. 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 realize lifting. The lifting mechanism is installed on a side washing device 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 of the transmission rotation mechanism corresponds to a turntable mechanism one by one. Each lower rotating shaft is coaxially clamped with the rotating shaft of the corresponding turntable mechanism in a non-relative rotatable manner.

[0008] 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 can be that the positioning groove is arranged on the turntable assembly and the positioning member is arranged on the bearing seat; or it can be that the positioning groove is arranged on the bearing seat and the bearing seat is arranged on the turntable assembly. Compared with the former where the positioning groove is arranged on the turntable assembly, it is more convenient to arrange the positioning member on the rotating shaft of the turntable assembly in the latter. And the positioning member is usually a positioning rod.

[0009] 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 lower rotating shaft in each of the turntable rotating mechanisms, the rotating shaft is coaxially inserted into the axial hole of each lower rotating shaft 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 edge washing device of the present invention has a variety of coaxial clamping structures between each lower rotating shaft in the transmission rotating 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 automatically cooperate to complete the correction work and edge washing work at the correction station and the edge washing station.

[0010] Furthermore, 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 provided on the transmission sleeve. The cross section of the lower rotating shaft body is usually small, and it is inconvenient to provide 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.

[0011] Further, 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 mounted 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 blanks 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 edge washing device of the present invention simultaneously drives all the lower rotating shafts in the same turntable rotating mechanism through the same transmission belt, and 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.

[0012] 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 the number of the lower rotating shafts in each of the turntable rotating mechanisms is more than one, 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, and the working efficiency is higher.

[0013] 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.

[0014] Further, vertical guide rods are provided on the lifting seat, and guide sleeves are vertically installed on the edge washing device frame. The vertical guide rods and the guide sleeves are in one-to-one correspondence, 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, so that the up and down movement of the transmission rotating mechanism is more stable.

[0015] Further, vacuum holes are provided on the turntable assembly. In the edge washing device of the present invention, during operation, continuous suction is performed through the vacuum holes, so that the green body placed on the turntable assembly can be adsorbed on the turntable assembly, preventing 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.

[0016] 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.

[0017] Furthermore, the special-shaped ceramic production line further includes a conveying device, and a first transfer device is provided between the edge washing device and the conveying device for transferring the green body on the conveying device to the edge washing device. During operation, after the conveying device transports the ceramic green body near the edge washing device, the first transfer device transfers the ceramic green body on the conveying device to the edge washing device for edge washing operation. Further, the special-shaped ceramic production line further includes a mud feeding device located on the side of the conveying device. The mud feeding device and the edge washing device are sequentially distributed along the conveying direction of the conveying device. The mud feeding device includes a mud feeding device and a clay kneading device. The feeding end of the clay kneading device is located at the discharging end of the mud feeding device. A second transfer device is provided between the clay kneading device and the conveying device for transferring the mud output by the clay kneading device to the conveying device. In the mud feeding device, the mud feeding device is mainly used for mud feeding to make the mud feeding operation automated; the clay kneading device can stir and press the mud to improve the vacuum degree and compactness of the mud, increasing the yield of the product. The setting of the mud feeding device and the second transfer device can not only make the ceramic quality better, but also greatly improve the automation degree of the production line.

[0018] Furthermore, the special-shaped ceramic production line further includes a mud patting mechanism. The mud feeding device, the mud patting mechanism and the edge washing device are sequentially distributed along the conveying direction of the conveying device. After the mud fed by the mud feeding device is transferred by the second transfer device into the mold cylinder on the conveying device, it is transported to the mud patting mechanism by the conveying device and is patted by the mud patting mechanism so that the mud in the mold cylinder on the conveying device is evenly spread out and closely adheres to the inside of the mold cylinder, thereby facilitating the more uniform mud on the peripheral wall of the green body for subsequent rolling forming.

[0019] Furthermore, the special-shaped ceramic production line further includes a first rolling forming device. The first rolling forming device and the edge washing device are sequentially distributed along the conveying direction of the conveying device. The first rolling forming device is used for rolling and forming the mud in the mold cylinder conveyed on the conveying device.

[0020] Furthermore, a second rolling forming device is further provided on one side of the conveying device. The second rolling forming device and the edge washing device are sequentially distributed along the conveying direction of the conveying device. In the special-shaped ceramic production line, the first rolling forming device can be mainly used for rolling and forming special-shaped ceramics, and the second rolling forming device can be mainly used for rolling and forming circular ceramics; the first rolling forming device for rolling and forming special-shaped ceramics and the second rolling forming device for rolling and forming circular ceramics usually only have different shapes of rolling dies, and other structures are basically the same. When the special-shaped ceramic production line produces two different-shaped ceramic green bodies at different times, the selection and use of the first rolling forming device and the second rolling forming device can enable the production to change the program at any time without having to change the die back and forth on the same rolling forming device.

[0021] Furthermore, the special-shaped ceramic production line also includes a trimming device, and the trimming device and the washing device are distributed in sequence along the conveying direction of the conveying device; the trimming device includes a trimming device frame, a vertical guide rail is provided on the trimming device frame, a lifting slide driven by a third driving mechanism and movable along the vertical guide rail is slidably installed on the vertical guide rail, a rotating table mechanism is provided on the lifting slide, the rotating table mechanism includes a swivel seat and a first driving mechanism, the swivel seat can be rotatably installed on the lifting slide, the first driving mechanism is fixedly installed on the lifting slide and is transmission-connected with the first driving mechanism, a horizontal guide rail located on one side of the rotating table mechanism is provided on the trimming device frame, a horizontal slide driven by a second driving mechanism and movable along the horizontal guide rail is slidably installed on the horizontal guide rail, a lifting screw is installed on the horizontal slide, a lifting mechanism is installed on the lifting screw, a tool holder driven by the lifting mechanism and movable and movable is installed on the lifting mechanism, and a scraper located above the swivel seat is installed on the tool holder. In the trimming device of the special-shaped ceramic production line of the present invention, by setting up a scraper and arranging a horizontal guide rail and a lifting mechanism, the scraper can be driven by the lifting mechanism to actively move closer to or away from the blank in the rotating mold barrel located on the rotating seat, and trim or not trim the blank in the mold barrel; and in the process of trimming, the scraper can be driven by the second driving mechanism to move horizontally, so that the scraper can scrape off the excess mud at various parts of the port of the special-shaped blank, and ensure the complete trimming of various parts of the port of the special-shaped blank. The trimming device has a high degree of automation, a fast working speed, and a mechanically unified trimming operation, so that the trimming quality of each blank is consistent, and the trimming effect of the blank is more guaranteed. Moreover, when the trimming device is applied to the special-shaped ceramic production line, the device cannot be moved, and the trimming device can fully automatically lift and trim the blank in the mold barrel without the need for a transfer device. Its convenient and fully automated operation makes the trimming efficiency extremely high.

[0022] Furthermore, the third driving mechanism is a cylinder.

[0023] Furthermore, a vacuum suction hole is provided on the rotating seat. The vacuum suction hole is convenient for connecting an air pump. After the rotating seat of the rotating table mechanism lifts the mold cylinder and the blank in the mold cylinder, air can be sucked to adsorb the mold cylinder, so that during the trimming process, the mold cylinder and the blank in the mold cylinder can be stably located on the rotating seat of the rotating table mechanism, and will not fall out of the rotating seat due to rotation or the action of the scraper.

[0024] Furthermore, the first driving mechanism is a motor.

[0025] Further, the second driving mechanism is a servo motor, and the second driving mechanism is usually connected to the horizontal slide by a lead screw. To drive the horizontal slide to move along the horizontal guide rail, the second driving mechanism can be a cylinder, a motor, etc. When the second driving mechanism is a motor, it is connected to the horizontal slide by a lead screw, and the lead screw converts the rotation of the second driving mechanism into the linear movement of the horizontal slide. Compared with a cylinder, the driving force of the motor is large, and when the second driving mechanism is a servo motor, the servo motor is not only easy to control, but also has high control precision, which is convenient for the fine movement of the scraper during the trimming process.

[0026] Further, the lifting mechanism is a cylinder, and the scraper is installed at the end of the piston rod of the lifting mechanism. The cylinder is small in size and convenient to install.

[0027] Further, the lifting mechanism is inclined. When trimming the special-shaped blank in the mold cylinder, the scraper needs to contact the special-shaped blank in the mold cylinder downward under the drive of the lifting mechanism, and there is a vertical force between the scraper and the special-shaped blank in the mold cylinder; and in order to cut off all the excess mud at the entire port of special-shaped blanks such as oval and square blanks, during the trimming process, the scraper also needs to move horizontally in a straight line along with the horizontal slide under the drive of the second driving mechanism. The horizontally moving scraper has a horizontal force with the blank in the mold cylinder. That is to say, during the trimming of the special-shaped blank in the mold cylinder, there are both vertical and horizontal forces between the scraper and the special-shaped blank in the mold cylinder. In this case, if the lifting mechanism is completely vertically arranged, at this time, although the vertical force can be transferred to the axis of the lifting mechanism, the horizontal force acts completely along the transverse direction of the lifting mechanism, which is likely to break the lifting mechanism; when the lifting mechanism is inclined, whether it is the vertical force or the horizontal force, both can be partially transferred to the axis of the lifting mechanism, thereby reducing the force on the transverse direction of the lifting mechanism, and effectively avoiding the lifting mechanism from being broken or damaged due to excessive transverse force.

[0028] Further, a lifting lead screw is installed on the horizontal slide, and a lifting mechanism is installed on the lifting lead screw. The lifting mechanism installed on the lifting lead screw on the horizontal slide can be adjusted up and down by the lifting lead screw. For the trimming of different blanks, this setting can make the use of the special-shaped ceramic production line of the present invention more convenient and have a wider application range.

[0029] Further, the tool rest includes a mounting plate, a mud cutting shaft, and a tool mounting bracket. The mounting plate is fixedly installed on the lifting mechanism. The mounting plate has a U-shaped notch. The mud cutting shaft passes through the U-shaped notch. The mounting plate clamps the mud cutting shaft in the U-shaped notch through a bolt passing through both side walls of the U-shaped notch. The tool mounting bracket is installed on the mud cutting shaft, and the scraping knife is installed on the tool mounting bracket. In this setting, by loosening or tightening the bolt passing through both side walls of the U-shaped notch, the mud cutting shaft can be made not to be clamped by the mounting plate, or clamped in the U-shaped notch of the mounting plate, that is, the mud cutting shaft and the mounting plate are detachably installed. The detachable installation of the mud cutting shaft enables the position of the scraping knife installed on the tool mounting bracket to be adjustable as needed, thus making the use of the trimming device of the present invention more flexible and having a wider application range.

[0030] Further, a finished product conveyor belt is also provided on one side of the edge washing device. A third transfer device is provided between the finished product conveyor belt and the edge washing device for transferring the ceramic blank that has been edge-washed on the edge washing device to the finished product conveyor belt. After the blank is edge-washed on the edge washing device, the third transfer device transfers the ceramic blank that has been edge-washed on the edge washing device to the finished product conveyor belt, and the finished product conveyor belt conveys the edge-washed ceramic blank out. This setting enables the special-shaped ceramic production line to be free of manual discharging and has a higher degree of automation.

[0031] Further, a fourth transfer device is provided between the finished product conveyor belt and the conveying device for transferring the ceramic blank on the conveying device to the finished product conveyor belt. The ceramic blanks that do not need to be edge-washed on the conveying device, such as round blanks, can be directly transferred to the finished product conveyor belt through the fourth transfer device and conveyed out by the finished product conveyor belt. The setting of the fourth transfer device can meet more different production requirements.

[0032] Further, an oven is provided on the conveying device. An oven is usually provided on the conveying device. The setting of the oven enables the blank after roll forming and edge trimming to enter the oven for drying as it is conveyed by the conveying device.

[0033] The special-shaped ceramic production line of the present invention provides a production device that can be used to produce special-shaped ceramics. In this production device, the automatic edge washing of the special-shaped blank by the edge washing device greatly improves the degree of automation of special-shaped ceramic production, thereby greatly improving the production efficiency of special-shaped ceramics, reducing manual operations in special-shaped ceramic production, and improving the production quality of special-shaped ceramics.

[0057] The following is a detailed description of the preferred implementation mode of the special - shaped ceramic production line of the present invention with reference to the accompanying drawings:

[0058] As Figure 1 shown, a special - shaped ceramic production line includes a conveying device 10, a mud - feeding device 1, a mud - patting mechanism 2, a first rolling - forming device 3, a second rolling - forming device 3', an edge - trimming device 4, and a side - washing device 5.

When the lower rotating shafts 5222 of the transmission rotating mechanism 522 in the turntable rotating mechanism 52 at the correction station 5101 and the edge washing station 5102 lift the corresponding turntable mechanism 51, each of the lower rotating shafts 5222 in the transmission rotating mechanism 522 at the correction station 5101 and the edge washing station 5102 is coaxially connected with the rotating shaft 5131 of the corresponding turntable mechanism 51 so as to be non-rotatable relative to each other, and the positioning member 5133 in the turntable mechanism 51 after being lifted is no longer located in the positioning groove 5111.

[0062] In the special-shaped ceramic production line of the present invention, in the edge washing device 5, a number of turntable mechanisms 51 are distributed on the periphery of the turntable 510. In each turntable mechanism 51, the turntable assembly 513 can revolve around the turntable 510 as the rotation center under the drive of the turntable 510. During the revolution of the turntable mechanism 51 with the turntable 510, the positioning member 5133 in each turntable mechanism 51 is located in the positioning groove 5111.

[0063] In the turntable mechanism 51 of the present invention, the rotating sleeve 512 is vertically and rotatably installed in the bearing seat 511. The rotating shaft 5131 passes through the rotating sleeve 512 movably and is key-connected to the rotating sleeve 512. The rotating shaft 5131 can move up and down relative to the rotating sleeve 512 but cannot rotate relatively. The rotating shaft 5131 and the rotating sleeve 512 can rotate together in the bearing seat 511.

[0064] In the turntable rotation mechanism 52 at the calibration station 5101 and the edge washing station 5102 of the special-shaped ceramic production line of the present invention, the transmission rotation mechanism 522 can be driven by the lifting mechanism 521 to realize lifting operation; the lower rotating shaft 5222 in the transmission rotation mechanism 522 can rotate under the drive of the rotation drive mechanism 5223; when the lower rotating shaft 5222 rotates, since each lower rotating shaft 5222 is coaxially clamped with the rotating shaft 5131 of the corresponding turntable mechanism 51 and cannot rotate relatively, the rotating lower rotating shaft 5222 drives the rotating shaft 5131 and the turntable 5132 at the upper end of the rotating shaft 5131, so that the turntable 5132 can rotate.

[0065] Special-shaped ceramic production line of the present invention. The edge washing device 5 is mainly used for edge washing of ceramic blanks. During specific operation, after the blank in the die barrel 100 is conveyed to the edge washing device 5 by the conveying device 10, the first transfer device 61 transfers the in-place die barrel 100 and the blank in the die barrel 100 to the turntable 5132 on the turntable 510 in the edge washing device 5. The ceramic blank transferred to the turntable 5132 rotates with the turntable 5132 under the drive of the turntable 510, and the rotating ceramic blank successively passes through the calibration station 5101 and the edge washing station 5102. At the calibration station 5101, the position calibration device 530 calibrates the position of the blank on the turntable 5132 driven by the turntable 510 and rotated to the calibration station 5101. At the edge washing station 5102, the edge washing device 540 performs edge washing on the blank on the turntable 5132 driven by the turntable 510 and rotated to the calibration station 5101. After the edge washing is completed and the ceramic blank is taken away from the edge washing station 5102, the edge-washed ceramic blank can be taken out from the turntable 5132.

[0066] In the special-shaped ceramic production line of the present invention, during the edge washing process, when the ceramic blank on the turntable 5132 rotates with the turntable 5132 to the calibration station 5101 for calibration or rotates to the edge washing station 5102 for edge washing, specifically, after the ceramic blank rotates with the turntable 5132 to the in-place position, the lifting mechanism 521 in the turntable rotation mechanism 52 below the turntable 510 drives the transmission rotation mechanism 522, causing the transmission rotation mechanism 522 to move upward. In the upward-moving transmission rotation mechanism 522, each lower rotating shaft 5222 jacks up the turntable assembly 513 in the corresponding turntable mechanism 51. After the turntable assembly 513 in the corresponding turntable mechanism 51 is jacked up, the positioning member 5133 on the jacked-up turntable assembly 513 in the turntable mechanism 51 is not in the positioning groove 5111, and the jacked-up turntable assembly 513 in the turntable mechanism 51 is no longer restricted by the positioning groove 5111 and has the condition for self-rotation; and when each lower rotating shaft 5222 jacks up the turntable assembly 513 in the corresponding turntable mechanism 51, each lower rotating shaft 5222 in the transmission rotation mechanism 522 is coaxially clamped with the rotating shaft 5131 of the corresponding turntable mechanism 51 without relative rotation. Then, driven by the rotation drive mechanism 5223, each lower rotating shaft 5222 in the transmission rotation mechanism 522, the rotating shaft 5131 of the corresponding turntable mechanism 51, and the turntable 5132 can be driven in sequence, so that the turntable 5132 and the ceramic blank thereon at the calibration station 5101 and the edge washing station 5102 rotate with the turntable 5132 for self-rotation. During the self-rotation of the ceramic blank, the position calibration device 530 calibrates the blank on the turntable assembly 513 that is driven by the turntable 510 to rotate to the calibration station 5101; the edge washing device 540 washes the blank on the turntable assembly 513 that is driven by the turntable 510 to rotate to the calibration station 5101.

[0067] In the special-shaped ceramic production line of the present invention, due to the differences in the alignment operation and the edge washing operation, the turntable 5132 and the ceramic blank thereon located at the alignment station 5101 usually rotate non-continuously with the turntable 5132. Specifically, at the alignment station 5101, after the turntable 5132 and the ceramic blank thereon rotate to each position, they stop, and the position calibration device 530 performs an alignment operation on the stopped ceramic blank. While the turntable 5132 and the ceramic blank thereon located at the edge washing station 5102 usually rotate continuously with the turntable 5132. Specifically, at the alignment station 5101, the turntable 5132 and the ceramic blank thereon rotate continuously without interruption. During the continuous rotation of the ceramic blank, the edge washing device 540 performs an edge washing operation on the stopped ceramic blank. The non-continuous rotation of the turntable 5132 at the alignment station 5101 and the continuous rotation of the turntable 5132 at the edge washing station 5102 can be obtained by driving and controlling the rotation drive mechanism 5223 in the two turntable rotation mechanisms 52.

[0068] In the special-shaped ceramic production line of the present invention, after the alignment operation at the alignment station 5101 or the edge washing operation at the edge washing station 5102 is completed, the lifting mechanism 521 in the corresponding turntable rotation mechanism 52 under the turntable 510 drives to drive the transmission rotation mechanism 522, the corresponding turntable 5132, and the ceramic blank on the turntable 5132 to move downward, so that the turntable assembly 513 falls back onto the turntable 510. After the positioning member 5133 in the turntable assembly 513 that has fallen back onto the turntable 510 returns to the positioning groove 5111, the turntable 510 rotates again.

[0069] In the special-shaped ceramic production line of the present invention, by arranging a limiting structure in each of the turntable mechanisms 51 where the positioning member 5133 cooperates with the positioning groove 5111, each of the turntable mechanisms 51 located on the turntable 510 cannot rotate freely under the limiting structure of the positioning member 5133 and the positioning groove 5111. Thus, during the rotation of the turntable 510, the relative positions of each of the turntable mechanisms 51 and the turntable 510 will not change, that is, it is ensured that during the rotation of the turntable 510, the relative positions of each of the turntable mechanisms 51 and the turntable 510 are unique and determined, thereby providing feasible conditions for subsequent alignment operations. At the same time, by arranging the turntable rotation mechanism 52 at the calibration station 5101 and the edge washing station 5102, each of the turntable mechanisms 51 rotated to the calibration station 5101 and the edge washing station 5102 can be lifted by the turntable rotation mechanism 52. After being lifted, the turntable mechanism 51 is no longer restricted by the limiting structure composed of the positioning member 5133 and the positioning groove 5111 and can rotate under the drive of the turntable rotation mechanism 52 to complete corresponding alignment and edge washing operations.

[0070] In the special-shaped ceramic production line of the present invention, the edge washing device 5 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 elliptical and square blanks, enabling special-shaped blanks to no longer be limited to manual feeding and blank 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.

[0071] In the special-shaped ceramic production line of the present invention, preferably, as Figure 7 and Figure 9 shown, when the positioning groove 5111 is provided on the bearing seat 511 and the positioning member 5133 is provided on the turntable assembly 513, the positioning groove 5111 is opened on the surface of the bearing seat 511, and the positioning member 5133 is located above the turntable 510 and horizontally arranged on the rotating shaft 5131 of the turntable assembly 513. In each of the turntable mechanisms 51, it can be that the positioning groove 5111 is provided on the turntable assembly 513 and the positioning member 5133 is provided on the bearing seat 511; or it can be that the positioning groove 5111 is provided on the bearing seat 511 and the bearing seat 511 is provided on the turntable assembly 513. Compared with the former where the positioning groove 5111 is provided on the turntable assembly 513, it is more convenient to provide the positioning member 5133 on the rotating shaft 5131 of the turntable assembly 513. And the positioning member 5133 is usually a positioning rod.

[0072] In the special-shaped ceramic production line of the present invention, as Figure 8 and Figure 9As shown, a deep groove ball bearing 51311 is generally sleeved on the rotating shaft 5131 of the turntable assembly 513 in each turntable mechanism 51. The deep groove ball bearing 51311 is located above the turntable 510 and below the turntable 5132. When the turntable assembly 513 of each turntable mechanism 51 is seated on the turntable 510, the deep groove ball bearing 51311 is supported on the bearing seat 511. The deep groove ball bearing 51311, which can bear a large axial load, serves as the direct load-bearing member of the turntable assembly 513, and the installation is more reliable.

[0073] The special-shaped ceramic production line of the present invention, preferably, as Figure 4 , Figure 5 and Figure 7 As shown, a limiting cross bar 5134 is provided at the lower end of the rotating shaft 5131 in each turntable mechanism 51. An axial hole 5224 and a limiting cross groove 5225 communicating with the axial hole 5224 are provided at the upper end of each lower rotating shaft 5222 in each turntable rotating mechanism 52. The axial hole 5224 of each lower rotating shaft 5222 in the transmission rotating mechanism 522 at the calibration station 5101 and the edge washing station 5102 coaxially inserts the rotating shaft 5131, and the limiting cross bar 5134 at the lower end of the rotating shaft 5131 is inserted into the limiting cross groove 5225. In the special-shaped ceramic production line of the present invention, there are various coaxial clamping structures between each lower rotating shaft 5222 in the transmission rotating mechanism 522 at the calibration station 5101 and the edge washing station 5102 and the rotating shaft 5131 of the corresponding turntable mechanism 51. It can be a common key connection, or the above-mentioned limiting cross bar 5134 is clamped in the limiting cross groove 5225 to limit the relative rotation between the lower rotating shaft 5222 and the rotating shaft 5131, so that the lower rotating shaft 5222 can drive the rotating shaft 5131 under the drive of the rotation drive mechanism 5223, and then the rotating shaft 5131 and the turntable 5132 thereon can automatically cooperate to complete the calibration work and edge washing work at the calibration station 5101 and the edge washing station 5102.

[0074] The special-shaped ceramic production line of the present invention, preferably, as Figure 12As shown, the lower rotating shaft 5222 includes a lower rotating shaft body 52221 and a transmission sleeve 52222 installed at the upper end of the lower rotating shaft body 52221. The shaft hole 5224 and the limiting transverse groove 5225 are formed in the transmission sleeve 52222. The cross-section of the lower rotating shaft body 52221 is generally small, making it inconvenient to provide the shaft hole 5224 and the limiting transverse groove 5225, and it is not easy to replace them when the shaft hole 5224 and the limiting transverse groove 5225 are damaged. Therefore, preferably, a transmission sleeve 52222 is sleeved on the lower rotating shaft body 52221, and the shaft hole 5224 and the limiting transverse groove 5225 are provided on the transmission sleeve 52222.

[0075] In the special-shaped ceramic production line of the present invention, preferably, the rotation driving mechanism 5223 is a motor. The rotation driving mechanism 5223 is drivingly connected to the lower rotating shaft 5222 through a belt mechanism 5226. The belt mechanism 5226 includes a main synchronous pulley 52261 connected to the rotation driving mechanism 5223, a slave synchronous pulley 52262 installed at the lower end of the lower rotating shaft 5222, and a transmission belt 52263 sleeved on the main synchronous pulley 52261 and all the slave synchronous pulleys 52262 in the same turntable rotation mechanism 52. During operation, the rotation driving mechanism 5223, which is a motor, rotates, successively driving the main synchronous pulley 52261, the transmission belt 52263, all the slave synchronous pulleys 52262 in the same turntable rotation mechanism 52, all the lower rotating shafts 5222 in the same turntable rotation mechanism 52, the rotating shaft 5131 clamped to the lower rotating shaft 5222, and the turntable 5132, so that the turntable 5132 and the green body thereon can rotate self, and cooperate to complete the calibration work and the edge washing work at the calibration station 5101 and the edge washing station 5102. In the special-shaped ceramic production line of the present invention, all the lower rotating shafts 5222 in the same turntable rotation mechanism 52 are simultaneously driven by the same transmission belt 52263, with high transmission efficiency, and the synchronization rate of all the lower rotating shafts 5222 in the same turntable rotation mechanism 52 and the turntable assembly 513 driven by them is higher.

[0076] In the special-shaped ceramic production line of the present invention, preferably, as Figure 10 shown, the number of the lower rotating shafts 5222 in each turntable rotation mechanism 52 is several. The number of the lower rotating shafts 5222 in each turntable rotation mechanism 52 can be one, two or more. When there are multiple lower rotating shafts 5222 in each turntable rotation mechanism 52, the green bodies on the corresponding multiple turntable assemblies 513 rotate simultaneously to complete the calibration work and the edge washing work at the calibration station 5101 and the edge washing station 5102, with higher working efficiency.

[0077] For the special-shaped ceramic production line of the present invention, preferably, the lifting mechanism 521 is a cylinder. The lifting mechanism 521 can be a structure with a motor driving a lead screw, or a cylinder, or other lifting mechanisms. In comparison, a cylinder has a large load-bearing capacity, a simple structure, and convenient control.

[0078] For the special-shaped ceramic production line of the present invention, preferably, as Figure 10 and Figure 11 shown, a vertical guide rod 5227 is provided on the lifting seat 5221, and a guide sleeve 5228 is vertically installed on the edge-washing device frame 520. The vertical guide rods 5227 and the guide sleeves 5228 correspond to each other one by one, and the vertical guide rods 5227 are movably inserted into the corresponding guide sleeves 5228. When the transmission and rotation mechanism 522 performs a lifting motion driven by the lifting mechanism 521, the vertical guide rods 5227 move within the guide sleeves 5228, and the guide sleeves 5228 limit and guide the vertical guide rods 5227, which can make the lifting motion of the transmission and rotation mechanism 522 more stable.

[0079] For the special-shaped ceramic production line of the present invention, preferably, as Figures 7 to 9 shown, the turntable assembly 513 is provided with vacuum holes 5135. During operation, by continuously sucking air through the vacuum holes 5135, the green body placed on the turntable assembly 513 can be adsorbed on the turntable assembly 513, preventing the green body on the turntable assembly 513 from falling off the turntable assembly 513 due to the revolution of the turntable 510 or its own rotation.

[0080] For the special-shaped ceramic production line of the present invention, a first transfer device 61 is provided between the edge-washing device 5 and the conveying device 10 for transferring the green body on the conveying device 10 to the edge-washing device 5. During operation, after the conveying device 10 conveys the ceramic green body to the vicinity of the edge-washing device 5, the first transfer device 61 transfers the ceramic green body on the conveying device 10 to the edge-washing device 5 for edge-washing operation.

[0081] For the special-shaped ceramic production line of the present invention, the conveying device 10 is usually an annular conveying device, which is mainly used to convey the mold cylinders, so that the mud or the formed green bodies in the mold cylinders are conveyed to various places, and corresponding production operations of various processes are carried out under the action of various different mechanisms such as the mud patting mechanism 2, the first rolling forming device 3, the second rolling forming device 3', the trimming device 4, and the edge-washing device 5, etc. For the special-shaped ceramic production line of the present invention, the conveying device 10 is a conventional existing structure, and the specific structure is not elaborated too much in the present invention.

[0082] In the special-shaped ceramic production line of the present invention, the mud feeding can be carried out manually or a mud feeding device 1 can be set up to complete it. In an embodiment of the special-shaped ceramic production line of the present invention, a mud feeding device 1 is arranged on the side of the conveying device 10. The mud feeding device 1 generally includes a mud feeding device 11 and a mud refining device 12. The feeding end of the mud refining device 12 is located at the discharging end of the mud feeding device 11. A second transfer device 62 is provided between the mud refining device 12 and the conveying device 10 for transferring the mud material output by the mud refining device 12 onto the conveying device 10.

[0083] In a preferred embodiment of the special-shaped ceramic production line of the present invention, the mud feeding device 1 is mainly used for mud feeding. Specifically, during mud feeding, the mud strip is placed on the mud feeding device 11 of the mud feeding device 1 and is lifted and conveyed by the mud feeding device 11. After being conveyed into the mud refining device 12, it is stirred and pressed by the mud refining device 12. After the stirring and pressing, the mud material output by the mud refining device 12 is transferred by the second transfer device 62 into the mold cylinder on the conveying device 10.

[0084] In the special-shaped ceramic production line of the present invention, the setting of the mud feeding device 1 can automate the mud feeding operation. While improving the automation degree of the production line, the stirring and pressing of the mud refining device 12 can improve the vacuum degree and compactness of the mud material, increase the yield of products, and make the ceramic quality better.

[0085] In the special-shaped ceramic production line of the present invention, after the mud material is put into the mold cylinder on the conveying device 10, the mud material in the mold cylinder on the conveying device 10 can be patted or not patted. When patting the mud material in the mold cylinder on the conveying device 10, it can be patted manually or mechanically.

[0086] In an embodiment of the special-shaped ceramic production line of the present invention, it further includes a mud patting mechanism 2. The mud feeding device 1, the mud patting mechanism 2 and the edge washing device 5 are arranged in sequence along the conveying direction of the conveying device 10. During the specific production process, after the mud material fed by the mud feeding device 1 is transferred by the second transfer device 62 into the mold cylinder on the conveying device 10, it is conveyed to the mud patting mechanism 2 by the conveying device 10 and is patted by the mud patting mechanism 2 so that the mud material in the mold cylinder on the conveying device 10 is evenly spread out and closely adheres to the inside of the mold cylinder, thereby facilitating the more uniform mud material on the peripheral wall of the ceramic blank for subsequent rolling forming. In the special-shaped ceramic production line of the present invention, the mud patting mechanism 2 generally includes a vertical reciprocating mechanism and a patting plate driven by the vertical reciprocating mechanism.

[0087] In an embodiment of the special-shaped ceramic production line of the present invention, it further includes a first rolling forming device 3. The first rolling forming device 3 and the edge washing device 5 are arranged in sequence along the conveying direction of the conveying device 10. The first rolling forming device 3 is used for rolling and forming the mud material in the mold cylinder conveyed by the conveying device 10.

[0088] In the special-shaped ceramic production line of the present invention, only one first roll-forming device 3 may be provided on one side of the conveying device 10, or a second roll-forming device 3' may be provided. In the embodiment of the special-shaped ceramic production line of the present invention, a second roll-forming device 3' is also included. In the special-shaped ceramic production line, the first roll-forming device 3 can be mainly used for roll-forming of special-shaped ceramics, and the second roll-forming device 3' can be mainly used for roll-forming of round ceramics; the first roll-forming device 3 used for roll-forming of special-shaped ceramics and the second roll-forming device 3' used for roll-forming of round ceramics usually differ only in the shape of the rolling mold, and the other structures are basically the same. When two ceramic blanks of different shapes are produced in time-sharing on the special-shaped ceramic production line, the selective use of the first roll-forming device 3 and the second roll-forming device 3' can enable the production program to be changed at any time without having to change the mold back and forth on the same roll-forming device.

[0089] The special-shaped ceramic production line of the present invention is characterized in that it can be used for the production of special-shaped ceramics such as oval ceramics and square ceramics, but is not limited to the production of special-shaped ceramics, but can also be used for the production of round ceramics. When the special-shaped ceramic production line of the present invention is used to produce round ceramics, the trimming of the round ceramic blank can usually be completed on a rolling forming device; the trimming of the special-shaped ceramic blank can be completed manually or mechanically.

[0090] In the special-shaped ceramic production line of the present invention, the first roll-forming device 3 and the second roll-forming device 3' are existing equipment, and their specific structures are not described in detail in the present invention.

[0091] In the embodiment of the special-shaped ceramic production line of the present invention, a trimming device 4 is also provided on one side of the conveying device 10. Figures 14 to 22As shown in the figure, the trimming device 4 includes a trimming device frame 410. A vertical guide rail 4102 is provided on the trimming device frame 410. A lifting slide 413 is slidably mounted on the vertical guide rail 4102 and can be driven by a third driving mechanism 4131 to move along the vertical guide rail 4102. A rotating table mechanism 41 is provided on the lifting slide 413. The rotating table mechanism 41 includes a turntable 411 and a first driving mechanism 412. The turntable 411 is rotatably mounted on the lifting slide 413. The first driving mechanism 412 is fixedly mounted on the lifting slide 413 and is in transmission connection with the first driving mechanism 412. A horizontal guide rail 4101 is provided on the trimming device frame 410 on one side of the rotating table mechanism 41. A horizontal slide 42 is slidably mounted on the horizontal guide rail 4101 and can be driven by a second driving mechanism 421 to move along the horizontal guide rail 4101. A lifting lead screw 422 is mounted on the horizontal slide 42. A lifting mechanism 43 is mounted on the lifting lead screw 422. A tool holder 44 that can be lifted by the lifting mechanism 43 is mounted on the lifting mechanism 43. A scraping knife 45 located above the turntable 411 is mounted on the tool holder 44.

[0092] In the preferred embodiment of the special-shaped ceramic production line of the present invention, during operation, after the green body after pressure molding in the mold cylinder 100 is conveyed to directly above the rotating table mechanism 41 by the conveying device 10, the rotating table mechanism 41 can be driven by the third driving mechanism 4131 to move upward, so that the turntable 411 lifts the mold cylinder 100 on the conveying device 10 and the green body in the mold cylinder 100, lifts them off the conveying device 10, and lifts them to a certain height. After reaching the trimming station, the scraping knife 45 can be driven by the second driving mechanism 421 and the lifting mechanism 43 to approach the mold cylinder 100 and the green body in the mold cylinder 100, and trim the green body in the mold cylinder 100; after trimming is completed and the scraping knife 45 is retracted under the drive of the second driving mechanism 421 and the lifting mechanism 43, the rotating table mechanism 41 can be driven by the third driving mechanism 4131 to move downward, so that the trimmed mold cylinder 100 and the green body in the mold cylinder 100 move downward and fall onto the conveying device 10, and are conveyed to the next process by the conveying device 10.

[0093] In the trimming device 4 of the special-shaped ceramic production line of the present invention, by setting up the scraper 45, and setting the horizontal guide rail 4101 and the lifting mechanism 43, the scraper 45 can be driven by the lifting mechanism 43 to actively move closer to or away from the blank in the rotating mold cylinder 100 located on the rotating seat 411, and trim or not trim the blank in the mold cylinder 100; and in the trimming process, the scraper 45 can be driven by the second driving mechanism 421 to move horizontally, so that the scraper 45 can scrape off the excess mud at various parts of the port of the special-shaped blank, and ensure the complete trimming of various parts of the port of the special-shaped blank. The trimming device 4 has a high degree of automation, a fast working speed, and a mechanically unified trimming operation, so that the trimming quality of each blank is consistent, and the trimming effect of the blank is more guaranteed. Moreover, when the trimming device 4 is applied to the special-shaped ceramic production line, the device cannot be moved. The trimming device 4 can automatically lift and trim the blank in the mold barrel 100 without the need for a transfer device. Its convenient and fully automated operation makes the trimming efficiency extremely high.

[0094] The special-shaped ceramic production line of the present invention is preferably as follows: Figure 18 As shown, a vacuum suction hole 4111 is provided on the rotating seat 411. The vacuum suction hole 4111 is provided to facilitate the connection of an air pump. After the rotating seat 411 of the rotating table mechanism 41 lifts the mold cylinder 100 and the blank inside the mold cylinder 100, air can be sucked to adsorb the mold cylinder 100, so that during the trimming process, the mold cylinder 100 and the blank inside the mold cylinder 100 can be stably located on the rotating seat 411 of the rotating table mechanism 41, and will not fall out of the rotating seat 411 due to rotation or the action of the scraper 45.

[0095] In the special-shaped ceramic production line of the present invention, the first driving mechanism 412 for driving the rotating seat 411 to rotate is usually a motor.

[0096] In the special-shaped ceramic production line of the present invention, the third driving mechanism 4131 that drives the rotating table mechanism 41 to move up and down along the vertical guide rail 4102 is usually a cylinder.

[0097] In the special-shaped ceramic production line of the present invention, preferably, the second driving mechanism 421 is a servo motor, and the second driving mechanism 421 is usually connected to the horizontal slide 42 by a screw. In order to drive the horizontal slide 42 to move along the horizontal guide rail 4101, the second driving mechanism 421 can be a cylinder, a motor, etc. When the second driving mechanism 421 is a motor, it is connected to the horizontal slide 42 by a screw, wherein the screw converts the rotation of the second driving mechanism 421 into a linear movement of the horizontal slide 42. Compared with the cylinder, the driving force of the motor is large, and when the second driving mechanism 421 is a servo motor, the servo motor is not only easy to control, but also has high control accuracy, which is convenient for the fine movement of the scraper 45 during the trimming process.

[0098] The special-shaped ceramic production line of the present invention, the lifting mechanism 43 is usually a cylinder, and the tool holder 44 is installed at the end of the piston rod of the lifting mechanism 43. The cylinder is small in volume and convenient to install.

[0099] In the special-shaped ceramic production line of the present invention, the lifting mechanism 43 can be vertically arranged or inclined. Preferably, the lifting mechanism 43 is inclined.

[0100] In the special-shaped ceramic production line of the present invention, when trimming the special-shaped blank in the mold cylinder 100, the scraping knife 45 needs to contact the special-shaped blank in the mold cylinder 100 downward under the drive of the lifting mechanism 43, and there is a vertical force between the scraping knife 45 and the special-shaped blank in the mold cylinder 100; and in order to cut off the redundant mud at the entire port of special-shaped blanks such as oval and square blanks, during the trimming process, the scraping knife 45 also needs to move horizontally in a straight line along with the horizontal slide 42 under the drive of the second drive mechanism 421. The scraping knife 45 moving horizontally in a straight line has a horizontal force with the blank in the mold cylinder 100. That is to say, during the trimming of the special-shaped blank in the mold cylinder 100, there are both vertical and horizontal forces between the scraping knife 45 and the special-shaped blank in the mold cylinder 100. In this case, if the lifting mechanism 43 is completely vertically arranged, at this time, although the vertical force can be transferred to the axis of the lifting mechanism 43, the horizontal force acts completely along the transverse direction of the lifting mechanism 43, which is likely to break the lifting mechanism 43; when the lifting mechanism 43 is inclined, whether it is the vertical force or the horizontal force, both can be partially transferred to the axis of the lifting mechanism 43, thereby reducing the force on the transverse direction of the lifting mechanism 43, and effectively avoiding the lifting mechanism 43 from being broken or damaged due to excessive transverse force.

[0101] In the special-shaped ceramic production line of the present invention, the lifting mechanism 43 can be directly installed on the horizontal slide 42; or a lifting lead screw 422 can be installed on the horizontal slide 42, and then the lifting mechanism 43 is installed on the lifting lead screw 422. Compared with the former, when the lifting mechanism 43 is installed on the lifting lead screw 422 on the horizontal slide 42, the up and down position can be adjusted by the lifting lead screw 422. For the trimming of different blanks, this setting can make the use of the special-shaped ceramic production line of the present invention more convenient and have a wider application range.

[0102] The special-shaped ceramic production line of the present invention, such as Figures 19 to 23As shown, preferably, the tool rest 44 includes a mounting plate 441, a mud cutting shaft 442, and a tool mounting bracket 443. The mounting plate 441 is fixedly mounted on the lifting mechanism 43. The mounting plate 441 has a U-shaped notch 4411. The mud cutting shaft 442 passes through the U-shaped notch 4411. The mounting plate 441 clamps the mud cutting shaft 442 within the U-shaped notch 4411 by a bolt 4412 passing through both side walls of the U-shaped notch 4411. The tool mounting bracket 443 is mounted on the mud cutting shaft 442, and the scraping knife 45 is mounted on the tool mounting bracket 443. In this setting, by loosening or tightening the bolt 4412 passing through both side walls of the U-shaped notch 4411, the mud cutting shaft 442 can be unclamped or clamped within the U-shaped notch 4411 of the mounting plate 441, that is, the mud cutting shaft 442 and the mounting plate 441 are detachably mounted. The detachable mounting of the mud cutting shaft 442 enables the position of the scraping knife 45 mounted on the tool mounting bracket 443 to be adjustable, making the use of the special-shaped ceramic production line of the present invention more flexible and having a wider application range.

This setting enables the special-shaped ceramic production line to be automatically discharged without manual operation, with a higher degree of automation.

The ceramic blank that does not need to be edge washed on the transfer device 10, such as a circular blank, can be directly transferred to the finished product conveyor belt 7 through the fourth transfer device 64 and conveyed out by the finished product conveyor belt 7. The setting of the fourth transfer device 64 can meet more different production requirements.

[0107] In a preferred embodiment of the special-shaped ceramic production line of the present invention, the process of producing special-shaped ceramics is generally as follows: After the mud material is lifted by the mud feeding device 1, it is transferred by the second transfer device 62 into the mold cylinder on the conveying device 10; the mud material in the mold cylinder is conveyed to the mud patting mechanism 2 along with the conveying device 10 and then patted by the mud patting mechanism 2; the mud material in the mold cylinder, after being patted by the mud patting mechanism 2, is further conveyed to the first rolling forming device 3 along with the conveying device 10 and rolled into shape by the first rolling forming device 3; the green body in the mold cylinder, after being rolled into shape by the first rolling forming device 3, is conveyed to the edge trimming device 4 along with the conveying device 10 and edge trimming operation is carried out by the edge trimming device 4; then, the green body with trimmed edges in the mold cylinder is further conveyed into the oven 8 along with the conveying device 10 for drying; the dried green body in the mold cylinder is output from the oven 8 and conveyed to the vicinity of the edge washing device 5, and then the first transfer device 61 removes the green body in the mold cylinder and transfers it to the edge washing device 5 for edge washing operation; the edge-washed green body is transferred by the third transfer device 63 to the finished product conveyor belt 7 and output by the finished product conveyor belt 7.

[0108] In a preferred embodiment of the special-shaped ceramic production line of the present invention, the process of producing circular ceramics is generally as follows: After the mud material is lifted by the mud feeding device 1, it is transferred by the second transfer device 62 into the mold cylinder on the conveying device 10; the mud material in the mold cylinder is conveyed to the mud patting mechanism 2 along with the conveying device 10 and then patted by the mud patting mechanism 2; the mud material in the mold cylinder, after being patted by the mud patting mechanism 2, is further conveyed to the second rolling forming device 3' along with the conveying device 10 and rolled into shape and trimmed by the second rolling forming device 3'; the green body in the mold cylinder, after being rolled into shape and trimmed by the second rolling forming device 3', is conveyed to the oven 8 along with the conveying device 10 for drying; the dried green body in the mold cylinder is output from the oven 8 and conveyed to the vicinity of the fourth transfer device 64; the fourth transfer device 64 removes the green body in the mold cylinder and transfers it to the finished product conveyor belt 7 and output by the finished product conveyor belt 7.

[0109] In the special-shaped ceramic production line of the present invention, the setting of the edge washing device 5 enables the edge washing of the special-shaped ceramic blank to be automated. After automation, the edge washing device 5 is arranged in the special-shaped ceramic production line for the production of special-shaped ceramic blanks, which can greatly improve the production efficiency of special-shaped ceramics, reduce manual operations in the production of special-shaped ceramics, and improve the production quality of special-shaped ceramics.
