Description

Technical Field

[0001] This utility model relates to a slip-cast ceramic blank production line. Background Technology

[0002] Slip casting is a commonly used method for forming ceramic blanks. It involves suspending ceramic particles in a liquid and then injecting the slurry into a porous mold. The liquid is then drawn out through the mold's pores, leaving a ceramic blank inside the mold. This method can produce arbitrarily complex shapes and large, thin-walled castings, and is therefore widely used in the manufacture of various ceramic products.

[0003] To meet the demands of large-scale industrial production, automated equipment is used to complete each step of the processing. For example, a grouting production line is disclosed in Chinese patent document CN116551831A, entitled "An Automated Grouting Production Line".

[0004] However, the applicant found that the above-mentioned grouting production line has an unreasonable structure. Due to the different structures of the clamping and transfer molds of each processing equipment and the different structures of each transfer equipment, there are too many types and quantities of parts. The manufacturing requires too many types of parts, resulting in a large number of spare parts and high manufacturing costs that are difficult to reduce.

[0005] To address this, the applicant improved the aforementioned technology and applied for a patent, publication number CN221872491U, entitled "Ceramic Slurry Casting Production Line." This ceramic slurry casting production line includes a frame, a mold conveying mechanism, a slurry casting mechanism, a mold drying mechanism, a mold opening mechanism, a mold bottom wiping mechanism, and two mold transfer mechanisms. Multiple workstations are sequentially arranged on the frame according to the processing order, forming a closed loop. The mold conveying mechanism is mounted on the frame and passes through the aforementioned workstations sequentially. This technology, due to the inclusion of a mold transfer mechanism, can effectively clamp and move the mold. Furthermore, the use of a mold transfer mechanism for all mold clamping and movement further optimizes the structure, reduces the types of parts, and decreases the variety of spare parts required for the manufacturing production line. The use of a single mold conveying mechanism to carry the mold through a loop through each workstation allows for more precise mold transport, facilitating control of each piece of equipment, ensuring good processing quality, and maintaining sufficient stability.

[0006] However, the applicant found that the above-mentioned technology, because the mold conveying mechanism can only move on the same horizontal plane, makes it impossible to further reduce the floor space of the production line. The floor space of the production line (which determines the length of the mold conveying mechanism) limits the size range of ceramic blanks that can be processed, and the working efficiency of the production line is also difficult to improve significantly. Utility Model Content

[0007] The purpose of this invention is to provide a slip-casting ceramic blank production line that can significantly reduce the floor space required, greatly expand the range of sizes of ceramic blanks that can be processed, and effectively improve work efficiency. The technical solution adopted is as follows:

[0008] A slip-cast ceramic blank production line includes a slip-casting forming device, a drying device, a mold operating device, and multiple mold transfer devices. The drying device includes a drying chamber, a hot air supply mechanism, and a mold conveying mechanism. The hot air supply mechanism is connected to the drying chamber and supplies hot air into it. The mold conveying mechanism is located inside the drying chamber. The slip-casting forming device and the mold operating device are respectively located on the left and right sides of the drying device. At least one mold transfer device is located between the slip-casting forming device and the drying device, and at least one mold transfer device is located between the mold operating device and the drying device. The mold conveying mechanism is vertical. The vertical rotary mold conveying mechanism includes a drive unit, two conveyor chains, multiple sprocket drive units, and multiple suspended mold support frames. Each sprocket drive unit includes a shaft and two sprockets. The shaft is rotatably mounted inside the drying chamber, and the two sprockets are respectively mounted on the shaft. The two conveyor chains correspond one-to-one with the two sprockets of each sprocket drive unit. Each conveyor chain is fitted onto all corresponding sprockets. The two conveyor chains are arranged parallel to each other. All suspended mold support frames are suspended between the two conveyor chains. The drive unit drives the shaft of one sprocket drive unit to rotate.

[0009] In a preferred embodiment, the conveyor chain bends and reciprocates at least twice in the vertical direction, forming multiple horizontally extended zones.

[0010] A more preferred embodiment is that the drying device has at least one left mold transfer station on the left side and at least one right mold transfer station on the right side. At least one mold transfer device transfers the mold between the slurry forming device and the suspended mold support frame of the vertical rotary mold conveying mechanism located at the left mold transfer station; at least one mold transfer device transfers the mold between the mold operating device and the suspended mold support frame of the vertical rotary mold conveying mechanism located at the right mold transfer station.

[0011] A better embodiment is that the grouting molding device is provided with a mold feeding station and a mold sending station, and the number of left mold transfer stations is one. The mold transfer device transfers all the molds located on the suspended mold support frame at the left mold transfer station to the mold feeding station, and then the mold transfer device transfers all the molds located at the mold sending station to the suspended mold support frame at the left mold transfer station.

[0012] A better embodiment is that the mold operating device is equipped with a mold bidirectional transfer station, with one mold transfer station on the right side. The mold transfer device transfers all the molds located on the suspended mold support frame at the right mold transfer station to the mold bidirectional transfer station. Then, the mold transfer device transfers all the empty molds that the mold operating device sent to the mold bidirectional transfer station to the suspended mold support frame (located at the right mold transfer station).

[0013] In a preferred embodiment, the suspended mold support frame includes a horizontal mounting frame, two suspension tripods, and at least one mold support plate. The horizontal mounting frame is positioned between two conveyor chains. The two suspension tripods are respectively mounted on the front and rear sides of the horizontal mounting frame, with their tops rotatably mounted on the two conveyor chains. The mold support plate is mounted on the horizontal mounting frame. The mold is placed onto the mold support plate.

[0014] A better solution is that the mold support plate has at least one ventilation hole.

[0015] The advantages of this invention compared to the prior art are that, because the vertical rotary mold conveying mechanism bends and extends back and forth in the vertical direction, it can significantly reduce the floor space and greatly expand the size range of ceramic blanks that can be processed. Therefore, by using the vertical rotary mold conveying mechanism to transport the molds in the drying device, and by setting the slip casting device and the mold operating device on the left and right sides of the drying device respectively, and by using different mold transfer devices to transfer the molds between the two devices and the drying device, the structure of the production line can be optimized, the floor space of the drying device can be significantly reduced, and the hot air can be fully utilized, resulting in a good energy-saving and emission-reduction effect.

[0025] like Figure 1-9As shown, in one embodiment of this application, a slip-cast ceramic blank production line includes a slip-casting forming device 1, a drying device 2, a mold operating device 3, and multiple mold transfer devices 4. The drying device 2 includes a drying chamber 201, a hot air supply mechanism 202, and a mold conveying mechanism. The hot air supply mechanism 202 connects to the drying chamber 201 and supplies hot air into the drying chamber 201. The mold conveying mechanism is disposed inside the drying chamber 201. The slip-casting forming device 1 and the mold operating device 3 are respectively disposed on the left and right sides of the drying device 2. At least one mold transfer device 4 is disposed between the slip-casting forming device 1 and the drying device 2, and at least one mold transfer device 4 is disposed between the mold operating device 3 and the drying device 2. The mold conveying mechanism is a vertical rotary mold conveying mechanism 203, which includes a drive mechanism. The unit comprises a 2031 unit, two conveyor chains 2032, multiple sprocket drive units 2033, and multiple suspended mold support frames 2034. Each sprocket drive unit 2033 includes a rotating shaft 20331 and two sprockets 20332. The rotating shaft 20331 is rotatably installed inside the drying chamber 201, and the two sprockets 20332 are respectively installed on the rotating shaft 20331. The two conveyor chains 2032 correspond one-to-one with the two sprockets 20332 of each sprocket drive unit 2033. Each conveyor chain 2032 is fitted onto all the corresponding sprockets 20332. The two conveyor chains 2032 are arranged parallel to each other. All suspended mold support frames 2034 are suspended between the two conveyor chains 2032. The drive unit 2031 drives the rotating shaft 20331 of one sprocket drive unit 2033 to rotate. Because the suspended mold support frame 2034 is suspended between two conveyor chains 2032, the chains can bend and extend back and forth in the vertical direction without affecting the mold placed on the suspended mold support frame 2034. The chain still moves smoothly along with the suspended mold support frame 2034. The drying device 2 is used for drying the mold after slurry injection (drying the slurry inside to form a ceramic blank) and also for drying the empty mold (removing the ceramic blank and cleaning the inside of the mold). Because the vertical rotary mold conveyor mechanism 203 is used to convey the mold and the empty mold, it can significantly save floor space, effectively utilize heat, and greatly reduce energy consumption.

[0026] like Figure 6 As shown, in an alternative embodiment, the drive unit 2031 includes a servo motor 20311, a reduction gearbox 20312, a transmission belt 20313, and two pulleys 20314 (only one is visible in the figure). The servo motor 20311 is connected to the reduction gearbox 20312. One pulley 20314 (not visible in the figure) is mounted on the output shaft of the reduction gearbox 20312, and the other pulley 20314 is mounted on the rotating shaft 20331 of a sprocket drive unit 2033. The transmission belt 20313 is looped around the two pulleys 20314.

[0027] like Figure 5 As shown, in one alternative embodiment, the conveyor chain 2032 bends vertically at least twice, forming multiple horizontal extension zones. In this embodiment, the conveyor chain 2032 bends vertically six times, forming five horizontal extension zones.

[0028] like Figure 3 , 4 As shown, in an alternative embodiment, the drying device 2 has at least one left mold transfer station A on the left side and at least one right mold transfer station B on the right side. At least one mold transfer device 4 transfers the mold between the injection molding device 1 and the suspended mold support frame 2034 of the vertical rotary mold conveying mechanism 203 located at the left mold transfer station A; at least one mold transfer device 4 transfers the mold between the mold operating device 3 and the suspended mold support frame 2034 of the vertical rotary mold conveying mechanism 203 located at the right mold transfer station B.

[0029] like Figure 1-4 As shown, in an alternative embodiment, the grouting molding device 1 is provided with a mold feeding station C, a mold sending station D, and a left mold transfer station A. A mold transfer device 4 transfers all the molds located at the left mold transfer station A to the mold feeding station C, and then the mold transfer device 4 transfers all the molds located at the mold sending station D to the suspended mold support frame 2034 (located at the left mold transfer station A).

[0030] In one alternative embodiment, the positions of the mold feeding station C and the mold ejection station D are... Figure 1 The embodiment shown is the opposite, that is, the mold feeding station C is located to the left of the left mold transfer station A, and the mold sending station D is located to the right of the left mold transfer station A.

[0031] like Figure 1 , 2 As shown in Figures 8 and 9, in an alternative embodiment, the mold operating device 3 is provided with a mold bidirectional transfer station E, and the number of right mold transfer stations B is one. A mold transfer device 4 transfers all the molds located on the suspended mold support frame at the right mold transfer station B to the mold bidirectional transfer station E. Then, the mold transfer device 4 transfers all the empty molds sent by the mold operating device 3 to the mold bidirectional transfer station E to the suspended mold support frame located at the right mold transfer station B.

[0032] like Figure 7As shown, in one alternative embodiment, the suspended mold support frame 2034 includes a horizontal mounting frame 20341, two suspended tripods 20342, and at least one mold support plate 20343. The horizontal mounting frame 20341 is disposed between two conveyor chains 2032. The two suspended tripods 20342 are respectively mounted on the front and rear sides of the horizontal mounting frame 20341, and the tops of the two suspended tripods 20342 are rotatably mounted on the two conveyor chains 2032. The mold support plate 20343 is mounted on the horizontal mounting frame 20341. The mold is placed on the mold support plate 20343.

[0033] like Figure 7 As shown, in one alternative embodiment, the mold support plate 20343 has at least one vent hole 203431. In this embodiment, there are multiple vent holes 203431. This structure facilitates the flow of hot air to heat the mold located on the mold support plate 20343.

[0034] like Figure 8 , 9 As shown, in one alternative embodiment, the mold operating device 3 includes a horizontal closed-loop mold conveying mechanism 301 and at least one mold opening device 302 disposed on one side of the horizontal closed-loop mold conveying mechanism 301. In this embodiment, the number of mold opening devices 302 is two.

[0035] The following is combined Figure 1-9 Let me introduce the work process:

[0036] The drive unit 203 of the vertical rotary mold conveying mechanism 203 of the drying device 2 operates, driving all the suspended mold support frames 2034 to follow the two conveying chains 2032 to make intermittent movements.

[0037] At the start of the operation, empty molds 5 are directly placed into the mold feeding station C of the grouting molding device 1 (in this embodiment, a conveyor belt and a robotic arm are used to feed the molds into the grouting molding device 1). During the operation, when a suspended mold support frame 2034 moves to the left mold transfer station A, the mold transfer device 4 (in this embodiment, the mold transfer mechanism of CN221872491U is used; in other alternative embodiments, other mechanical structures with the same function can also be used) transfers all empty molds 5 on the suspended mold support frame 2034 located at the left mold transfer station A to the mold feeding station C of the grouting molding device 1 in sequence; then the mold transfer device 4 transfers all molds 5 (which have completed grouting processing) located at the mold delivery station D to the suspended mold support frame 2034 (located at the left mold transfer station A);

[0038] The suspended mold support frame 2034 follows the two conveyor chains 2032 of the vertical rotary mold conveying mechanism 203 in an intermittent motion. It moves from left to right at the bottom of the drying chamber 201 to the right mold transfer station B. During this process, the ceramic blanks in all the molds 5 located on the suspended mold support frame 2034 are dried.

[0039] The mold transfer device 4 transfers the mold 5 (containing a dried ceramic blank) located on the suspended mold support frame 2034 at the right mold transfer station B to the mold bidirectional transfer station E of the mold operation device 3. The horizontal closed-loop mold conveying mechanism 301 of the mold operation device 3 delivers these molds 5 to the operation station. The mold opening device 302 (in this embodiment, the mold opening mechanism of CN221872491U) is used to open the mold 5. Then, the ceramic blank inside the mold 5 is removed, the mold 5 is cleaned, and the mold is closed. The horizontal closed-loop mold conveying mechanism delivers these empty molds 5 to the mold bidirectional transfer station E. The mold transfer device 4 transfers the empty molds 5 located at the mold bidirectional transfer station E to the suspended mold support frame 2034 at the right mold transfer station B.

[0040] The suspended mold support frame 2034 follows the two conveyor chains 2032 of the vertical rotary mold conveying mechanism 203 in an intermittent motion. It bends and moves back and forth from bottom to top on the right side of the bottom of the drying chamber 201 and then moves down to the left mold transfer station A on the left side of the bottom of the drying chamber 201.

[0041] This process, repeated continuously, allows for the continuous processing and transport of ceramic blanks.

[0042] In this embodiment, the grouting molding device 1, the mold operating device 3, and the mold transfer device 4 simultaneously process two molds 5.

[0043] In other alternative embodiments, the grouting molding device 1, the mold operating device 3, and the mold transfer device 4 can process one mold 5 or other numbers of molds 5 simultaneously.

[0044] Because a vertical rotary mold conveying mechanism 203, which bends and extends repeatedly in the vertical direction, is used to convey the mold 5 within the drying device 2, and the slip casting device 1 and mold operating device 3 are respectively located on the left and right sides of the drying device 2 and the mold 5 is transferred between the two devices and the drying device 2 through different mold transfer devices 4, the structure of the production line is more reasonable. This significantly reduces the floor space occupied by the drying device 2 (because the vertical rotary mold conveying mechanism 203 bends and extends repeatedly in the vertical direction, which can significantly reduce the floor space), greatly expands the size range of processable ceramic blanks (the size of the ceramic blanks is not easily limited by the length of the mold conveying mechanism of the drying device 2), and allows for full utilization of hot air, resulting in excellent energy saving and emission reduction effects. In addition, since the structure of the slip casting device 1, mold operating device 3, and mold transfer device 4 is not significantly different from that of CN221872491U, it will not be described in detail in this paper.

[0045] 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 utility model patent concept are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may 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 utility model or exceed the scope defined in these claims, they should all fall within the protection scope of this utility model.
