Description

Technical Field

[0001] This invention relates to a ceramic blank forming production equipment, and more specifically to a structurally sound ceramic blank forming production line that can process ceramic blanks with small size limitations, good drying effect and consistency, and high production efficiency. Background Technology

[0002] Currently, the method for manufacturing ceramic blanks using clay usually involves feeding a clay rod into a mold, then integrating it into a rolling station, using a rolling machine to roll the clay rod inside the mold, then sending it into an oven to dry to obtain a ceramic blank, and finally trimming the ceramic blank to obtain the finished ceramic blank.

[0003] To maximize the production efficiency of ceramic blank production lines using the aforementioned method, the applicant improved the structure of traditional ceramic blank production lines and applied for a patent, publication number CN210850775U, entitled "A Ceramic Rolling and Drying Production Line." This ceramic rolling and drying production line includes a mold conveying mechanism, a rolling mechanism, and a drying mechanism. Its key features are: the rolling mechanism has a mold feeding station, a clay placement station, a rolling station, and a mold delivery station arranged sequentially in the working order; the mold conveying mechanism includes a mold feeding lifting unit and a mold lowering delivery unit, with the inlet of the mold feeding lifting unit located at the mold delivery station of the rolling mechanism, and the outlet of the mold feeding lifting unit connected to the inlet of the mold lowering delivery unit, and the outlet connected to the outlet of the mold lowering delivery unit located at the mold feeding station of the rolling mechanism; the drying mechanism includes a sealing cover and a heating device, with the sealing cover covering the heating device and the mold conveying mechanism. The above technology significantly reduces the footprint of the mold conveying mechanism due to improvements, and further reduces the overall machine footprint due to improvements in the rolling mechanism, effectively reducing production costs.

[0004] However, the applicant discovered that the above technology also has problems such as a limited range of applicable product sizes, difficulty in controlling the drying effect, etc., as detailed below:

[0005] 1. Because the mold conveying mechanism adopts a spiral-shaped ascending and descending structure design, the height of the product is limited. Once the height of the product exceeds the allowable range, production is impossible.

[0006] 2. Since the drying time of ceramic blanks is controlled by the conveyor speed, different sizes of products require different drying times. If the volume of the ceramic blank increases too much and the conveyor speed decreases too much, it will seriously affect the production efficiency, thus making it difficult to guarantee the production efficiency.

[0007] 3. Due to the complex structure of the mold conveying mechanism and the fact that many of its components are located at a relatively high position, the installation, debugging, maintenance, and replacement of parts of the mold conveying mechanism are quite troublesome.

[0008] 4. Due to the lack of hot air reuse design, the energy consumption of the above-mentioned mold conveying mechanism is difficult to reduce significantly, and it is impossible to eliminate the adverse environmental impact as much as possible. In addition, the mold conveying mechanism needs to continuously transport the mold to a high place, which requires more energy compared with the traditional solution of transporting the mold in the horizontal plane. Summary of the Invention

[0009] The purpose of this invention is to provide a reasonably structured ceramic blank forming production line. This production line can process ceramic blanks with minimal size limitations, achieve good drying results and consistency, and has high production efficiency. The technical solution adopted is as follows:

[0010] A reasonably structured ceramic blank forming production line includes a mold conveying mechanism, a clay rod feeding mechanism, a rolling mechanism, and a drying mechanism. The ceramic blank forming production line has a closed-loop conveying processing line consisting of a forward conveying processing line and a reverse conveying processing line connected end-to-end. The feeding station and rolling station are sequentially arranged on the forward conveying processing line, and the drying station is arranged on the reverse conveying processing line. The mold conveying mechanism includes a frame, a longitudinal conveying unit, a transverse array conveying unit, a first mold transfer device, and a second mold transfer device. The longitudinal conveying unit, transverse array conveying unit, first mold transfer device, and second mold transfer device are respectively mounted on the frame. The longitudinal conveying unit carries multiple molds and moves intermittently along the longitudinal direction of the ceramic blank forming production line. The process involves sequentially sending each mold to the feeding station and the rolling station. The first mold transfer device sequentially sends the molds located at the outlet of the longitudinal conveying unit into the inlet of the transverse array conveying unit to obtain transverse mold groups. The transverse array conveying unit carries multiple transverse mold groups in an intermittent reverse motion along the longitudinal direction of the ceramic blank forming production line, passing through the drying station in sequence. The second mold transfer device sequentially sends all the molds of the transverse mold groups leaving the drying station outlet into the inlet of the longitudinal conveying unit one by one. The clay rod feeding mechanism sequentially feeds clay rods into the molds located at the feeding station. The rolling mechanism sequentially rolls the clay rods in the molds located at the rolling station to obtain ceramic blanks to be dried. The drying mechanism dries the ceramic blanks in the molds of all transverse mold groups located in the drying station to obtain ceramic blanks.

[0011] In a preferred embodiment, the mold conveying mechanism further includes multiple mold support plates for supporting the mold. Each mold support plate is respectively disposed on the longitudinal conveying unit, the transverse array conveying unit, the first mold transfer device, and the second mold transfer device. Each mold support plate holds a mold, forming a mold unit to be conveyed. The longitudinal conveying unit, the transverse array conveying unit, the first mold transfer device, and the second mold transfer device convey the mold by pushing the entire mold unit to be conveyed.

[0012] In a preferred embodiment, the longitudinal conveying unit is a longitudinal mold conveyor belt extending longitudinally along the ceramic blank forming production line. The longitudinal mold conveyor belt includes a first drive unit, a single-mold longitudinal conveyor track group, a first annular conveyor chain group, two first conveyor sprocket groups, two first rotating shafts, and multiple actuating frames. The single-mold longitudinal conveyor track group includes two first tracks, the first annular conveyor chain group includes two first annular conveyor chains, each first conveyor sprocket group includes two first conveyor sprockets, and the two first tracks are respectively mounted on a frame. The two first tracks extend longitudinally along the ceramic blank forming production line and are parallel to each other. Two first rotating shafts are rotatably mounted on the frame. Two first conveyor sprocket sets are mounted on the two first rotating shafts and are respectively located at the left and right ends of the frame. A first annular conveyor chain is respectively fitted onto one of the first conveyor sprockets of the two first conveyor sprocket sets, and another first annular conveyor chain is respectively fitted onto the other first conveyor sprocket of the two first conveyor sprocket sets. Each actuating frame is connected to two first annular conveyor chains at both ends, and all actuating frames are evenly distributed along the extension direction of the two first annular conveyor chains. A first drive unit is mounted on the frame and drives a first rotating shaft to rotate.

[0013] A preferred embodiment is that the transverse array conveyor unit is an array mold conveyor belt extending longitudinally along the ceramic blank forming production line; the array mold conveyor belt includes a second drive mechanism, an array mold pushing mechanism, and multiple array conveyor mold support rail groups. Each array conveyor mold support rail group includes two second rails respectively mounted on a frame. The two second rails extend longitudinally along the ceramic blank forming production line and are parallel to each other. All array conveyor mold support rail groups are evenly distributed transversely along the ceramic blank forming production line; the array mold pushing mechanism includes two... The system comprises a second rotating shaft, multiple push rods, and multiple chain push units. The two second rotating shafts are rotatably mounted on the left and right ends of the frame, respectively. The second drive mechanism has a second output shaft connected to the second rotating shaft. Each chain push unit includes a second annular conveyor chain and two second conveyor sprockets. The two second conveyor sprockets are respectively mounted on the two second rotating shafts, and the second annular conveyor chain is fitted onto the two second conveyor sprockets. Each push rod is connected to the outer side of the second annular conveyor chain of all chain push units, and all push rods extend laterally along the ceramic blank forming production line, and all push rods are parallel to each other.

[0014] A better solution is that the distance between any two push rods is greater than the length of the mold support plate.

[0015] A preferred solution is to have the same number of molds in all horizontal mold groups, ranging from 3 to 10. Since the purpose of the horizontal mold groups is to change the traditional conveying mode of individual molds sequentially passing through the drying mechanism to a mode of multiple molds being conveyed simultaneously, thereby improving drying efficiency and reducing the length of the drying mechanism, the number of molds in each horizontal mold group cannot be too small, otherwise the goal of improving drying efficiency and reducing the length of the drying mechanism will not be achieved. However, the number of molds in each horizontal mold group cannot be too large either, otherwise the width of the drying mechanism will be too large, resulting in an excessively large footprint for the entire production line, making it difficult to place in the producer's factory and increasing production costs. Therefore, 3-10 molds is a suitable range.

[0016] In a preferred embodiment, the drying mechanism includes a housing, a drying gas supply device, and two heat recovery pipes. The housing is mounted on a frame and forms a drying space within it. The inlet and outlet of this drying space are located on the left and right sides of the frame, respectively. The drying gas supply device is mounted on the housing, which has a heat gas inlet. The heat gas outlet of the drying gas supply device is connected to the heat gas inlet of the housing. The two heat recovery pipes are mounted on the housing, with their inlets connected to the inlet and outlet of the drying space, respectively, and their outlets connected to the drying gas supply device. This design allows the drying gas supply device to input hot gas into the drying space through the heat gas inlet of the housing. Furthermore, the dried and cooled heat gas is recovered and reused at the inlet and outlet of the drying space, effectively saving energy consumption and minimizing the adverse environmental impact of exhaust gases.

[0017] A better solution is that the housing is equipped with multiple hot air guiding devices, each including a fan bracket and multiple fans. The fan bracket is mounted on the frame, and each fan is mounted on the fan bracket.

[0018] A better solution is that the number of hot air guiding devices and the number of horizontal mold groups located inside the box are the same and correspond one-to-one, and all the fans of each hot air guiding device are located above the corresponding horizontal mold group.

[0019] A better solution is that the number of fans in the corresponding hot air guiding device and the number of molds in the horizontal mold group are the same and correspond one-to-one, with each fan located above the corresponding mold.

[0020] The advantages of this invention compared to existing technologies are that, because the mold conveying mechanism uses a longitudinal conveying unit to sequentially transport individual molds through the feeding and rolling stations, and a transverse array conveying unit to transport transverse mold groups through the drying station, the entire mold conveying mechanism completes mold transport within a single plane. This minimizes restrictions on the size of the molds to be processed, and particularly effectively eliminates limitations on mold height. Furthermore, the transverse array conveying unit uses transverse mold groups arranged in an array to intermittently transport molds through the drying mechanism, significantly increasing the number of molds that can be dried simultaneously at the drying station. Therefore, it ensures that each mold receives a sufficient amount of time at the drying station to complete the drying process. The horizontal array conveyor unit outputs molds at a speed that keeps pace with the vertical conveyor unit, ensuring high production efficiency without excessively increasing the overall floor space of the production line. The drying mechanism outputs hot air from the center of the box to the inlet and outlet sides, and uses a fan to blow hot air onto the molds below, ensuring that each mold is dried relatively evenly by a hot airflow moving from top to bottom. Moreover, within the drying mechanism, each mold receives a hot airflow for drying after each intermittent movement stops, resulting in excellent drying performance. The mold conveying mechanism and the drying mechanism work closely together to ensure high production efficiency of the production line while guaranteeing the drying effect.

[0031] like Figure 1 , 2 As shown, a structurally sound ceramic blank forming production line in one embodiment of this application includes a mold conveying mechanism 1, a clay rod feeding mechanism 2, a rolling mechanism 3, and a drying mechanism 4. The ceramic blank forming production line has a closed-loop conveying processing line consisting of a forward conveying processing line and a reverse conveying processing line connected end-to-end. Feeding station A and rolling station B are sequentially arranged on the forward conveying processing line, and the drying station is arranged on the reverse conveying processing line. In this application, the direction from right to left of the mold conveying mechanism 1 is the longitudinal forward direction of the ceramic blank forming production line, and the direction from left to right of the mold conveying mechanism 1 is the longitudinal reverse direction of the ceramic blank forming production line.

[0032] like Figure 1-8 As shown in the above embodiment, the mold conveying mechanism 1 includes a frame 101, a longitudinal conveying unit 102, a transverse array conveying unit 103, a first mold transfer device 104, and a second mold transfer device 105. The longitudinal conveying unit 102, the transverse array conveying unit 103, the first mold transfer device 104, and the second mold transfer device 105 are respectively mounted on the frame 101. The longitudinal conveying unit 102 carries multiple molds and moves intermittently along the longitudinal direction of the ceramic blank forming production line, sequentially sending each mold to the feeding station A and the rolling station B. The first mold transfer device 104 sequentially sends the molds located at the outlet of the longitudinal conveying unit 102 into the rolling station. A transverse mold group is obtained at the entrance of the transverse array conveyor unit 103. The transverse array conveyor unit 103 carries multiple transverse mold groups in an intermittent reverse motion along the longitudinal direction of the ceramic blank forming production line, passing through the drying station in sequence. The second mold transfer device 105 sends all the molds of the transverse mold group leaving the drying station outlet into the entrance of the longitudinal conveyor unit 102 one by one. The mud rod feeding mechanism 2 feeds mud rods into the mold located at the feeding station A in sequence. The rolling mechanism 3 rolls the mud rods in the mold located at the rolling station B in sequence to obtain the ceramic blank to be dried. The drying mechanism 4 dries the ceramic blanks in the molds of all transverse mold groups located in the drying station to obtain the ceramic blank.

[0033] like Figure 1-3 As shown, in an alternative embodiment, the mold conveying mechanism 1 further includes a plurality of mold support plates 106 for supporting the mold. Each mold support plate 106 is respectively disposed on the longitudinal conveying unit 102, the transverse array conveying unit 103, the first mold transfer device 104, and the second mold transfer device 105. Each mold support plate holds a mold to form a mold unit to be conveyed. The longitudinal conveying unit, the transverse array conveying unit, the first mold transfer device, and the second mold transfer device convey the mold by conveying the entire mold unit to be conveyed. In other words, the longitudinal conveying unit 102 moves with multiple mold support plates 106, thereby conveying the mold units to be conveyed intermittently and sequentially sending the molds of each mold unit to the feeding station A and the rolling station B. The first mold transfer device 104 sequentially sends the mold units to be conveyed located at the outlet of the longitudinal conveying unit 102 into the inlet of the transverse array conveying unit 103, resulting in a group of mold units to be conveyed. The group of mold units to be conveyed is a group of mold units to be conveyed arranged horizontally and conveyed synchronously. It consists of a transverse mold group at the top and a mold support plate group at the bottom. The transverse array conveying unit 103 carries the group of mold units to be conveyed sequentially through the drying station in the reverse direction of the longitudinal direction of the ceramic blank forming production line. The second mold transfer device 105 sequentially sends all the mold units to be conveyed from the drying station outlet into the inlet of the longitudinal conveying unit 102. At the inlet of the longitudinal conveying unit 102, the producer uses manual labor or equipment to remove and send out the ceramic blanks of the mold units to be conveyed after all processing has been completed.

[0034] like Figure 4 , 5 As shown, in one alternative embodiment, the longitudinal conveying unit 102 is a longitudinal mold conveyor belt extending longitudinally along the ceramic blank forming production line. The longitudinal mold conveyor belt conveys multiple molds sequentially along the positive longitudinal direction of the ceramic blank forming production line.

[0035] like Figure 4 , 5As shown, in one alternative embodiment, the longitudinal mold conveyor belt includes a first drive unit 1021, a single mold longitudinal conveyor track group 1022, a first annular conveyor chain group 1023, two first conveyor sprocket groups 1024, two first rotating shafts 1025, and multiple actuating frames 1026. The single mold longitudinal conveyor track group 1022 includes two first tracks 10221, the first annular conveyor chain group 1023 includes two first annular conveyor chains 10231, each first conveyor sprocket group 1024 includes two first conveyor sprockets 10241, the two first tracks 10221 are respectively mounted on the frame 101, the two first tracks 10221 extend longitudinally along the ceramic blank forming production line and are parallel to each other, and the two first rotating shafts 1025 are rotatably mounted on the frame. On frame 101, two first conveyor sprocket sets 1024 are respectively mounted on two first rotating shafts 1025, and the two first conveyor sprocket sets 1024 are respectively located at the left and right ends of frame 101. A first annular conveyor chain 10231 is respectively fitted onto one of the first conveyor sprockets 10241 of the two first conveyor sprocket sets 1024, and another first annular conveyor chain 10231 is respectively fitted onto the other first conveyor sprocket 10241 of the two first conveyor sprocket sets 1024. Each actuating frame 1026 is connected to two first annular conveyor chains 10231 at both ends, and all actuating frames 1026 are evenly distributed along the extension direction of the two first annular conveyor chains 10231. A first drive unit 1021 is mounted on frame 101 and drives a first rotating shaft 1025 to rotate.

[0036] like Figure 4 , 5 As shown, in one alternative embodiment, the first drive unit 1021 includes a first motor 10211 and a first reducer 10212. The first motor 10211 is connected to the first reducer 10212. The first reducer 10212 has a first output shaft, and the first output shaft is connected to a first rotating shaft 1025. The first output shaft of the first motor 10211 rotates, driving the first rotating shaft 1025 to rotate, thereby driving two first conveyor sprockets 10241 mounted on the first rotating shaft 1025 to rotate, causing two first annular conveyor chains 10231 to move. The two first annular conveyor chains 10231 respectively drive the first conveyor sprockets 10241 of two first conveyor sprocket groups 1024 mounted on another first rotating shaft 1025 to rotate.

[0037] like Figure 3-5As shown, in one alternative embodiment, the longitudinal mold conveyor belt has a single mold conveying zone. The two first tracks 10221 within the single mold conveying zone are at the same height, the two first annular conveyor chains 10231 within the single mold conveying zone are at a height lower than the two first tracks 10221, and all the actuating frames 1026 within the single mold conveying zone are at a height higher than the two first tracks 10221. The single mold conveying zone refers to the zone in which a single mold unit to be conveyed (only one mold unit to be conveyed laterally, corresponding to the synchronous conveying of multiple mold units to be conveyed laterally by the transverse array conveyor unit 103) is conveyed sequentially.

[0038] like Figure 7 As shown, in one alternative embodiment, the transverse array conveyor unit 103 is an array mold conveyor belt extending longitudinally along the ceramic blank forming production line. The array mold conveyor belt sequentially conveys multiple transverse mold groups in the opposite direction along the longitudinal direction of the ceramic blank forming production line, with all molds in each transverse mold group distributed transversely along the ceramic blank forming production line.

[0039] like Figure 7 As shown, in an alternative embodiment, the array-type mold conveyor belt includes a second drive mechanism 1031, an array-type mold pushing mechanism 1032, and multiple array-type conveyor mold support track groups 1033. Each array-type conveyor mold support track group 1033 includes two second tracks 10331 respectively mounted on the frame 101. The two second tracks 10331 extend longitudinally along the ceramic blank forming production line and are parallel to each other. All array-type conveyor mold support track groups 1033 are evenly distributed transversely along the ceramic blank forming production line. The array-type mold pushing mechanism 1032 includes two second rotating shafts 10321, multiple pushing rods 10322, and multiple chain pushing units 10323. The 321 are rotatably mounted on the left and right ends of the frame 101 respectively. The second drive mechanism 1031 has a second output shaft, which is connected to a second rotating shaft 10321. Each chain pushing unit 10323 includes a second annular conveyor chain 103231 and two second conveyor sprockets 103232. The two second conveyor sprockets 103232 are respectively mounted on two second rotating shafts 10321. The second annular conveyor chain 103231 is sleeved on the two second conveyor sprockets 103232. Each push rod 10322 is connected to the outside of the second annular conveyor chain 103231 of all chain pushing units 10323. All push rods 10322 extend laterally along the ceramic blank forming production line and are parallel to each other.

[0040] The second drive mechanism 1031 includes a second motor and a second reducer. The second motor and the second reducer are respectively mounted on the frame 101, and the second motor is connected to the second reducer.

[0041] like Figure 3 , 7 As shown, in one alternative embodiment, the distance between any two push rods 10322 is greater than the length of the mold support plate 106.

[0042] like Figure 1-3 As shown, in an alternative embodiment, the direction in which the transverse mold assembly conveyor belt drives the transverse mold assembly to move is opposite to the direction in which the mold conveyor belt drives the mold to move, so that the movement trajectory of the longitudinal conveyor unit 102 and the movement trajectory of the transverse array conveyor unit 103 form a closed annular conveyor trajectory.

[0043] like Figure 6 As shown, in one alternative embodiment, the first mold transfer device 104 includes a third drive mechanism 1041, two third tracks 1042, two third rotating shafts 1043, two third annular conveyor chains 1044, two third conveyor sprocket sets 1045, and multiple first transfer levers 1046. The two third tracks 1042 are respectively mounted parallel to each other on the frame 101. The two third rotating shafts 1043 are respectively rotatably mounted on the frame 101. The two third conveyor sprocket sets 1045 each include two third conveyor sprockets 10451. Each third conveyor... The two third conveying sprockets 10451 of the sprocket assembly 1045 are respectively mounted on two third rotating shafts 1043. The third drive mechanism 1041 has a third output shaft, which is connected to a third rotating shaft 1043. Two third annular conveying chains 1044 are respectively sleeved on the two third conveying sprockets 10451 of the two third conveying sprocket assemblies 1045. The two third annular conveying chains 1044 are parallel to each other. The two ends of each first transfer lever 1046 are respectively connected to the outside of the two third annular conveying chains 1044, and all the first transfer levers 1046 are parallel to each other.

[0044] The third drive mechanism 1041 includes a third motor and a third reducer. The third motor and the third reducer are respectively mounted on the frame 101, and the third motor is connected to the third reducer.

[0045] like Figure 8As shown, in one alternative embodiment, the second mold transfer device 105 includes a fourth drive mechanism 1051, two fourth tracks 1052, two fourth rotating shafts 1053, two fourth annular conveyor chains 1054, two fourth conveyor sprocket sets 1055, and multiple second transfer levers 1056. The two fourth tracks 1052 are respectively mounted parallel to each other on the frame 101, the two fourth rotating shafts 1053 are respectively rotatably mounted on the frame 101, and the two fourth conveyor sprocket sets 1055 each include two fourth conveyor sprockets 10551. Each fourth conveyor sprocket group 1055 has two fourth conveyor sprockets 10551 mounted on two fourth shafts 1053 respectively. The fourth drive mechanism 1051 drives one of the fourth shafts 1053 to rotate. Two fourth annular conveyor chains 1054 are respectively fitted onto the two fourth conveyor sprockets 10551 of the two fourth conveyor sprocket groups 1055. The two fourth annular conveyor chains 1054 are parallel to each other. The two ends of each second transfer lever 1056 are respectively connected to the outside of the two fourth annular conveyor chains 1054, and all the second transfer levers 1056 are parallel to each other.

[0046] like Figure 8 As shown, in an alternative embodiment, the fourth drive mechanism 1051 includes a fourth motor 10511, a fourth reducer 10512, an annular transmission chain 10513, and two transmission gears 10514. The fourth motor 10511 and the fourth reducer 10512 are respectively mounted on the frame 101. The fourth motor 10511 is connected to the fourth reducer 10512. The two transmission gears 10514 are respectively mounted on the output shaft of the reducer 10512 and the aforementioned fourth rotating shaft 1053. The annular transmission chain 10513 is sleeved on the two transmission gears 10514.

[0047] like Figure 1-3 As shown, in one alternative embodiment, all transverse mold groups have the same number of molds, namely five. Since the purpose of the transverse mold groups is to change the traditional conveying mode of single molds sequentially passing through the drying mechanism 4 to a mode of multiple molds being conveyed synchronously, thereby improving drying efficiency and reducing the length of the drying mechanism 4, the number of molds in the transverse mold groups cannot be too small, otherwise the goal of improving drying efficiency and reducing the length of the drying mechanism 4 will not be achieved. However, the number of molds in the transverse mold groups cannot be too large either, otherwise the width of the drying mechanism 4 will be too large, resulting in an excessively large footprint for the entire production line, making it difficult to accommodate the producer's factory and leading to excessively high production costs. Therefore, five molds are a more suitable number.

[0048] In one alternative embodiment, all transverse mold groups have the same number of molds, which is 3.

[0049] In one alternative embodiment, all transverse mold groups have the same number of molds, which is 8.

[0050] In one alternative embodiment, all transverse mold groups have the same number of molds, 10 each.

[0051] like Figure 1-3 As shown, in an alternative embodiment, the mud rod feeding mechanism 2 is located at the feeding station A of the transverse array conveying unit 103, the rolling mechanism 3 is located at the rolling station B of the transverse array conveying unit 103 (the rolling mechanism 3 is located outside the transverse array conveying unit 103, and in this embodiment, the rolling station B covers a portion of the transverse array conveying unit 103 directly opposite the rolling mechanism 3 and the rolling mechanism 3), and the drying mechanism 4 is located at the drying station.

[0052] like Figure 1 , 2 As shown, in an alternative embodiment, a third mold transfer device 107 is further provided between the rolling mechanism 3 and the transverse array conveying unit 103 for transferring molds between the rolling mechanism 3 and the transverse array conveying unit 103. That is, the third mold transfer device 107 transfers the molds of the transverse array conveying unit 103 to the rolling mechanism 3, and at the same time transfers the molds of the rolling mechanism 3 to the transverse array conveying unit 103, so that the molds of the two (rolling mechanism 3 and transverse array conveying unit 103) are interchangeable.

[0053] like Figure 9 , 10 As shown, in one alternative embodiment, the drying mechanism 4 includes a housing 401, a drying gas supply device 402, and two heat recovery pipes 403. The housing 401 is mounted on the frame 101 and forms a drying space within the housing 401. The inlet 4011 and outlet 4012 of the drying space are located on the left and right sides of the frame 101, respectively. The drying gas supply device 402 is mounted on the housing 401 and has a heat inlet (in this embodiment, the heat inlet is located on the left side of the drying gas supply device 402). The heat outlet of the drying gas supply device 402 (in this embodiment, the heat outlet is located on the left side of the drying gas supply device 402) is connected to the heat inlet of the housing 401. The two heat recovery pipes 403 are respectively mounted on the housing 401, and the inlets of the two heat recovery pipes 403 are respectively connected to the inlet 4011 and outlet 4012 of the drying space, and the outlets of the two heat recovery pipes 403 are respectively connected to the drying gas supply device 402. This design allows the drying gas supply device 402 to input hot gas into the drying space through the hot gas inlet of the housing 401, and the hot gas that has completed the drying work and cooled down can be recovered and reused at the inlet and outlet of the drying space, effectively saving heat energy consumption and minimizing the adverse environmental impact of the exhaust gas.

[0054] like Figure 10As shown, in an alternative embodiment, a plurality of hot air guiding devices 404 are installed inside the housing 401. The hot air guiding device 404 includes a fan bracket 4041 and a plurality of fans 4042. The fan bracket 4041 is mounted on the frame 101, and each fan 4042 is mounted on the fan bracket 4041.

[0055] like Figure 10 As shown, in an alternative embodiment, the number of hot air guiding devices 404 and the number of horizontal mold groups located in the housing 401 are the same and correspond one-to-one, and all the fans 4042 of each hot air guiding device 404 are located above the corresponding horizontal mold group.

[0056] like Figure 10 As shown, in an alternative embodiment, the number of fans 4042 of the corresponding hot air guiding devices 404 and the molds of the horizontal mold group are the same and correspond one-to-one, with each fan 4042 located above the corresponding mold.

[0057] like Figure 9 , 10 As shown, in one alternative embodiment, the drying gas supply device 402 is located in the middle of the top surface of the housing 401.

[0058] In an alternative embodiment, the drying gas supply device 402 is equipped with heating equipment and a blower. The heating equipment heats the air inside the drying gas supply device 402, and the blower outputs hot air at a suitable temperature downwards to dry the ceramic blanks in the drying space.

[0059] like Figure 9 , 10 As shown, in one alternative embodiment, the drying gas supply device 402 has a hot gas inlet pipe 4021 connected to an external hot gas delivery device. The drying gas supply device 402 is able to receive hot gas from an external hot gas delivery device (such as hot air from a ceramic sintering production line) through the hot gas inlet pipe 4021.

[0060] like Figure 1-3 As shown, in an alternative embodiment, the ceramic blank forming production line further includes a trimming station C and a trimming mechanism 5, which trims the ceramic blank located at the trimming station C. In this embodiment, after the ceramic blank is transferred to the trimming mechanism 5 by a robotic arm to complete the trimming process, it is manually fed out, while the mold support plate 106 and the mold on it (i.e., the mold unit to be conveyed) continue to be conveyed forward.

[0061] like Figure 1 , 2As shown, in an alternative embodiment, the ceramic blank forming production line further includes a ceramic blank finished product feeding mechanism 6. In this embodiment, the ceramic blank finished product feeding mechanism 6 uses a conveyor belt to receive the ceramic blank finished product from the trimming mechanism 5 and feeds the ceramic blank finished product out.

[0062] The following is combined Figure 1-10 Let me introduce the work process:

[0063] The ceramic blank forming production line uses a longitudinal conveying unit 102 to convey the mold (mold unit to be conveyed) to the feeding station A for feeding, and then to the rolling station B for rolling to form a ceramic blank to be dried. Then, a transverse array conveying unit 103 conveys the transverse mold group (mold unit group to be conveyed) to the drying station for drying to obtain the finished ceramic blank.

[0064] This structural design allows the entire mold conveying mechanism 1 to transport molds within a single plane, minimizing restrictions on the size of the molds to be processed. In particular, it effectively eliminates limitations on mold height. Furthermore, the use of an array-type transverse array conveying unit 103 to transport molds through the drying mechanism 4 significantly increases the number of molds that can be dried simultaneously at the drying station. Therefore, while ensuring that each mold has sufficient time to dry at the drying station, the speed at which the transverse array conveying unit 103 outputs molds can keep up with the speed at which the longitudinal conveying unit 102 transports molds. This ensures high production efficiency of the production line without excessively increasing its floor space.

[0065] Since this application achieves mold conveying by pushing the left or right end of the mold support plate 106 (i.e., pushing the mold unit to be conveyed), and the drying mechanism 4 outputs hot air from the middle to both the inlet and outlet sides, and uses a fan to blow air onto the mold below, each mold is dried relatively evenly by a hot airflow moving from top to bottom. Moreover, within the drying mechanism, each mold receives a hot airflow for drying after each intermittent movement stops, resulting in good drying effect. In some other alternative embodiments, the producer can control each fan separately to adjust the flow rate of the hot airflow at certain locations, improve the drying effect at one or more locations, and further enhance the drying effect. This adjustment is relatively easy to implement and has good results, making it suitable for producers with high product requirements.

[0066] The mold conveying mechanism 1 and the drying mechanism 4 work closely together, thus ensuring high production efficiency of the production line while guaranteeing the drying effect.

[0067] Furthermore, it should be noted that the names of the various parts of the specific embodiments described in this specification may differ. All equivalent or simple variations made to the structure, features, and principles described in this invention are included within the scope of protection of this invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this invention or exceed the scope defined in these claims, all of which should fall within the scope of protection of this invention.
