Ceramic green body production line

Abstract

This invention belongs to the technical field of ceramic production equipment, specifically disclosing a ceramic body production line. In the front-to-back direction, the first, second, and third powered roller conveyors are aligned to facilitate the transition of molds and fixture assemblies from right to left. The first powered roller conveyor moves the fixture assembly containing the dry mold from right to left onto the second powered roller conveyor, where slurry is injected into the dry mold via a slurry injection device, transforming it into a slurry-filled mold. The second powered roller conveyor moves the fixture assembly containing the slurry-filled mold from right to left onto the third powered roller conveyor. Then, through the lifting and lowering of a third lifting mechanism, the fixture assembly containing the slurry-filled mold, currently resting on the third powered roller conveyor, is transferred to the body forming device, completing the transition of the mold and fixture assembly. The entire process, through automated mechanical operation, significantly reduces manual labor and improves production efficiency.

Description

Technical Field

[0001] This invention relates to the field of ceramic production equipment technology, and particularly to a ceramic blank production line. Background Technology

[0002] In the ceramics industry, the shaping of everyday ceramics (such as ceramic figurines and toys) often employs slip casting. This involves pouring slurry, made from raw clay, into a dried plaster mold. Because plaster molds are absorbent, the slurry near the inner wall of the mold absorbs water, forming a layer of clay that mirrors the shape of the mold's inner wall. This layer thickens over time. After a period of time, the excess slurry is poured out of the mold, while the clay layer near the inner wall remains inside. After even longer, the clay layer naturally shrinks and detaches from the mold's inner wall, thus shaping the ceramic body.

[0003] In existing technologies, the above processes are mostly operated manually, resulting in low automation and low production efficiency. Therefore, it is necessary to design production lines to transform them. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides a ceramic green body production line, which solves the problems of low automation and low production efficiency in ceramic green body production.

[0024] A fourth powered roller conveyor is mounted on the third frame and can be moved up and down via a fourth lifting mechanism. The mechanical structure of the fourth lifting mechanism is the same as that of the third lifting mechanism, and in the front-to-back direction, the fourth lifting mechanism is located behind the third lifting mechanism.

[0025] A fixture assembly release device is located between the wet mold drying device and the blank forming device, and in the front-rear direction, it is located behind the dry mold grouting device. It includes a fourth frame and a release mechanism. The release mechanism is used to release the blank forming mold from the fixture assembly. The release mechanism is vertically movable on the fourth frame via a fifth lifting mechanism. The fifth lifting mechanism includes a second servo motor, a column, and a mounting box. The mounting box is installed on the top of the fourth frame. The column passes through the mounting box and is connected to the mounting box via a first sliding mechanism.

The second servo motor is installed on the side wall of the mounting box, and the output end of the second servo motor is equipped with a gear that meshes with a rack fixed on the column.

[0026] A fifth powered roller conveyor is installed on the fourth frame and located below the loosening mechanism;

[0027] The sixth powered roller conveyor is mounted on the first frame and can be moved up and down via a sixth lifting mechanism.

[0032] As a further embodiment, the drying mechanism includes a combustion chamber, a blower, an air distribution box, and air ducts. The combustion chamber is located at the front end of the first frame, and the air outlet of the combustion chamber is connected to the air inlet of the blower. The air outlet of the blower is connected to the air inlet of the air distribution box. The air distribution box has two or more air outlets. There are two or more air ducts located below the first frame, and the front end of the air duct is connected to the air outlet of the air distribution box. The rear end of the air duct is closed, and multiple air nozzles are provided on the air duct.

[0033] The beneficial effects of this invention are as follows: The first, second, and third powered roller conveyors are aligned in the front-to-back direction, facilitating the transition of the mold and fixture assembly from right to left. The first powered roller conveyor moves the fixture assembly containing the dry mold from right to left onto the second powered roller conveyor, where slurry is injected into the dry mold via a slurry injection device, transforming it into a slurry-filled mold. The second powered roller conveyor moves the fixture assembly containing the slurry-filled mold from right to left onto the third powered roller conveyor. Then, through the lifting and lowering of the third lifting mechanism, the fixture assembly containing the slurry-filled mold, which is currently resting on the third powered roller conveyor, is transferred to the billet forming device, completing the transition of the mold and fixture assembly. Finally, on the billet forming device, the slurry in the mold is formed into a billet. The entire process, through automated mechanical operation, significantly reduces manual labor, thereby improving production efficiency. Attached Figure Description

[0061] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0062] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," "third," "fourth," "fifth," "sixth," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0063] Unless otherwise explicitly specified and limited, when terms such as "set," "set in," "connected," and "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0064] When directional terms appear, they are used to facilitate the description of the present invention and to simplify the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific scope of protection of the present invention.

[0065] It should be noted that the usage status of mold 15 changes as follows: dry mold has been dried – mold for slip casting – mold for forming the blank – wet mold has removed the blank and is awaiting drying. Furthermore, the blank is taken to the kiln for firing to form daily-use ceramics. The mold, on the other hand, is taken to dry and dehydrate for the next slip casting.

[0066] As attached Figure 1-2 As shown, the ceramic blank production line provided in this embodiment includes a wet mold drying device 1, a first powered roller conveyor 2, a dry mold grouting device 3, a second powered roller conveyor 4, a blank forming device 5, and a third powered roller conveyor 6.

[0067] As attached Figure 3As shown, the wet mold drying device 1 includes a first frame 11, a drying mechanism 12, and a first chain conveyor 13 disposed on the first frame 11. The first chain conveyor 13 enables the clamping assembly 7 containing the wet mold 15 to move counterclockwise around the first frame 11. The drying mechanism 12 is used to dry the wet mold 15. Therefore, in the feasible solution, the drying mechanism 12 includes a combustion chamber 121, a blower 122, an air distribution box 123, and air ducts 124. The combustion chamber 121 is located at the front end of the first frame 11. The air outlet of the combustion chamber 121 is fixedly connected to the air inlet of the blower 122. The air outlet of the blower 122 is fixedly connected to the air inlet of the air distribution box 123. The air distribution box 123 has two or more air outlets. There are two or more air ducts 124 located below the first frame 11. The front end of the air duct 124 is fixedly connected to the air outlet of the air distribution box 123, the rear end of the air duct 124 is closed, and multiple air nozzles 1241 are provided on the air duct 124. The hot air generated by the combustion chamber 121 is blown into the air distribution box 123 by the blower 122. The air is buffered and pressurized in the air distribution box 123, so that the hot air can be stably and continuously blown out through the air nozzles 1241 of the air duct 124. Since the air duct 124 is located below the first frame 11 and the combustion chamber 121 is located at the front end of the first frame 11, the mold 15 can always be in contact with hot air at a high temperature as the clamping assembly 7 containing the wet mold 15 moves counterclockwise around the first frame 11 by the first chain conveyor 13. After being dried into a dry mold 15, the mold 15 is still a long distance away from the dry mold grouting device 3 when it continues to move counterclockwise above the first frame 11. This allows the mold 15 to be fully dried into a dry mold 15 and also allows the mold 15 to cool down during the movement, which is convenient for subsequent grouting.

[0068] As attached Figure 2 , 5 As shown, the first powered roller conveyor 2 is mounted on the first frame 11 and can be moved up and down via the first lifting mechanism 21. The first powered roller conveyor 2 is a self-powered roller conveyor. The first lifting mechanism 21 drives the first powered roller conveyor 2 to rise, thereby transferring the clamp assembly 7 containing the dry mold from the first chain conveyor 13 to the first powered roller conveyor 2.

[0069] As attached Figure 6As shown, the dry mold grouting device 3 is located on the left side of the wet mold drying device 1. It includes a second frame 31, a grouting gun 32, and a buffer tank 33 for holding grout. The inlet of the grouting gun 32 is connected to the buffer tank 33 through a pipe. A switch control valve is provided at the inlet of the grouting gun 32. The buffer tank 33 provides a stable supply of grout to the grouting gun 32, and the switch control valve can control whether the grout enters the grouting gun 32. Multiple grouting guns 32 can be installed as needed. In actual application, the grout in the buffer tank 33 is pumped into the buffer tank 33 from the grout pool through a pump body, providing a continuous supply of grout. The grouting gun 32 is mounted on the second frame 31 and can be moved up and down via a second lifting mechanism 35. The buffer tank 33 is installed on top of the second frame 31. The second lifting mechanism 35 drives the grouting gun 32 to rise and fall, thereby adjusting the grouting gun 32 to the height of the grout level and reducing air bubbles generated during grouting.

[0070] As attached Figure 2 , 6 As shown, the second powered roller conveyor 4 is installed on the second frame 31 and located below the grouting gun 32. The second powered roller conveyor 4 can stop the clamp assembly 7 equipped with the dry mold. After the grouting gun 32 injects grout, it can push the clamp assembly 7 equipped with the grouting mold to move.

[0071] As attached Figure 1-2 As shown, the blank forming device 5 is located to the left of the dry mold grouting device 3, so that the dry mold grouting device 3 is positioned between the wet mold drying device 1 and the blank forming device 5. In an embodiment where the dry mold grouting device 3 is installed above the blank forming device 5, the grouting time differs from the mold pouring time during the blank forming process, causing interference and affecting the blank forming (during pouring, some parts of the blank become too thick). This solution separates the grouting operation of the dry mold grouting device 3 from the blank forming operation of the blank forming device 5, ensuring they do not interfere with each other and do not affect production progress or product quality. The billet forming device 5 includes a third frame 51 and a second chain conveyor 52 disposed on the third frame 51. Since the second chain conveyor 52 enables the clamp assembly 7 with the grouting mold to move clockwise around the third frame 51, during this movement, when the clamp assembly 7 with the grouting mold moves to the front end of the third frame 51, the grouting mold will tilt, thereby pouring out the excess mud in the mold. During the subsequent clockwise movement of the mold 15, the mud layer in the mold gradually forms a billet.

[0072] Additionally, as attached Figure 2 , 7As shown in Figure 8, the third powered roller conveyor 6 is mounted on the third frame 51 and can be moved up and down via the third lifting mechanism 61. Specifically, by lifting and lowering the third lifting mechanism 61, the clamping assembly 7 with the grouting mold, which is parked on the third powered roller conveyor 6, is transferred to the second chain conveyor 52 of the billet forming device 5, thus completing the transition between the grouting mold and the clamping assembly 7.

[0073] In this design, the first powered roller conveyor 2, the second powered roller conveyor 4, and the third powered roller conveyor 6 are aligned in the front-to-back direction, facilitating the transition of the mold and fixture assembly 7 from right to left. The first powered roller conveyor 2 moves the fixture assembly 7 containing the dry mold from right to left onto the second powered roller conveyor 4, where slurry is injected into the dry mold via the dry mold slurry injection device 3, transforming it into a slurry-filled mold. The second powered roller conveyor 4 moves the fixture assembly 7 containing the slurry-filled mold from right to left onto the third powered roller conveyor 6, and then, through the lifting and lowering of the third lifting mechanism 61, transfers the fixture assembly 7 containing the slurry-filled mold, which is currently resting on the third powered roller conveyor 6, onto the billet forming device 5, completing the transition of the mold and fixture assembly 7. Then, on the billet forming device 5, the slurry in the mold is formed into a billet. The entire process, through automated mechanical operation, significantly reduces manual labor, thereby improving production efficiency.

[0074] It should be noted that, as shown in the attached document Figure 2 As shown, the first chain conveyor 13 and the second chain conveyor 52 have the same mechanical structure and achieve the same structural benefits. The difference lies in that the first chain conveyor 13 moves the clamping assembly 7 containing the mold 15 counterclockwise around the first frame 11, while the second chain conveyor 52 moves the clamping assembly 7 containing the mold 15 clockwise around the third frame 51. This can be achieved by adjusting the direction of rotation of the reduction motor 131 in the first chain conveyor 13 and the second chain conveyor 52.

[0075] In some embodiments, as shown in the appendix Figure 2-4 As shown, the first chain conveyor 13 includes a geared motor 131 and sprockets 132 disposed on both sides and at the front and rear ends of the first frame 11. The sprockets 132 on both sides of the first frame 11 are connected by a coupling 133, and the sprockets 132 at the front and rear ends of the first frame 11 are connected by a chain 134. The geared motor 131 is mounted on the first frame 11, and its output end is connected to the coupling 133 for transmission. Multiple spaced-apart drag blocks 135 are fixed on the chain 134, and each drag block 135 has a positioning groove 1351. The geared motor 131 drives the coupling 133, thereby causing the sprockets 132 to drive the chain 134 to rotate, and the drag blocks 135 move accordingly.

[0076] Furthermore, as attached Figure 2-4 As shown, the first chain conveyor 13 also includes a first linear guide rail 136 and a second linear guide rail 137 fixedly connected to both sides of the first frame 11, and C-shaped guide rails 138 disposed on both sides and at the front and rear ends of the first frame 11. The first linear guide rail 136 and the second linear guide rail 137 are distributed vertically, with the first linear guide rail 136 above the second linear guide rail 137. This vertical distribution design effectively shortens the length of the first frame 11 in the front-rear direction, saving space and making effective use of space. The C-shaped guide rail 138 is coaxial with the sprocket 132, and the upper end of the C-shaped guide rail 138 is above the first linear guide rail 136, thereby effectively connecting the rails. This allows the pulley 74 to abut against the C-shaped guide rail 138, and when the pulley 74 transitions from the C-shaped guide rail 138 to the first linear guide rail 136, the pulley 74 can accurately land on the first linear guide rail 136, preventing it from detaching from the guide rail. The lower end of the C-shaped guide rail 138 is flush with the second linear guide rail 137, thereby connecting the first linear guide rail 136 and the second linear guide rail 137 through the C-shaped guide rail 138 to form a closed track.

[0077] As attached Figure 14 As shown, the clamping assembly 7 includes a support plate 71 and multiple clamping mechanisms 72 disposed on the support plate 71. The clamping mechanisms 72 are used to clamp and fix the mold 15. Positioning posts 73 and two pulleys 74 are provided at both ends of the support plate 71. Specifically, the positioning posts 73 are welded and fixed to the support plate 71, while the pulleys 74 are rotatably connected to the support plate 71. The positioning posts 73 are located between the two pulleys 74 and can be placed in the positioning groove 1351. The two pulleys 74 can be slidably disposed on the first linear guide rail 136, the C-shaped guide rail 138, and the second linear guide rail 137. The reduction motor 131 drives the coupling shaft 133, thereby causing the sprocket 132 to drive the chain 134 to rotate, and the drag block 135 moves accordingly, thereby moving the entire clamping assembly 7. Furthermore, since the positioning post 73 is located between the two pulleys 74, which can be slidably mounted on the first linear guide rail 136, the C-shaped guide rail 138, and the second linear guide rail 137, it can not only bear the weight of the clamping assembly 7, but also provide lateral force for the positioning post 73, thus solving the problem that the entire clamping assembly 7 will swing when only the positioning post 73 is placed in the positioning groove 1351.

[0078] It should be noted that, as shown in the attached document Figure 2-4As shown, the first linear guide 136 is away from the opening of the positioning groove 1351. At this time, the opening of the positioning groove 1351 of the drag block 135 above the first linear guide 136 faces upward, and the opening of the positioning groove 1351 faces away from the first linear guide 136. For the first powered roller conveyor 2, the first lifting mechanism 21 drives the first powered roller conveyor 2 to rise, which facilitates the positioning post 73 of the clamp assembly 7 to disengage from the positioning groove 1351. For the third powered roller conveyor 6, the third lifting mechanism 61 drives the third powered roller conveyor 6 to fall, which facilitates the positioning post 73 of the clamp assembly 7 to be placed in the positioning groove 1351, and the drag block 135 stably drives the clamp assembly 7 to move.

[0079] Meanwhile, as attached Figure 2-4 As shown, the C-shaped guide rail 138 is close to the opening of the positioning groove 1351. That is, when the clamping assembly 7 moves to the C-shaped guide rail 138, the opening of the positioning groove 1351 of the drag block 135 in the C-shaped guide rail faces the C-shaped guide rail 138. The sprocket 132 supports the drag block 135 on the chain 134, so that the pulley 74 of the clamping assembly 7 abuts against the C-shaped guide rail 138, realizing the transition of the clamping assembly 7 from the first linear guide rail 136 to the C-shaped guide rail 138, and preventing the positioning post 73 of the clamping assembly 7 from disengaging from the positioning groove 1351.

[0080] As attached Figure 2-4 As shown, the second linear guide 137 is close to the opening of the positioning groove 1351. That is, when the clamping assembly 7 moves to the second linear guide 137, the opening of the positioning groove 1351 of the dragging block 135 above the second linear guide 137 faces downward and the opening of the positioning groove 1351 faces the second linear guide 137. The sprocket 132 supports the dragging block 135 on the chain 134, so that the pulley 74 of the clamping assembly 7 abuts against the second linear guide 137, which enables the dragging block 135 to stably drive the clamping assembly 7 to move, realizing the transition of the clamping assembly 7 from the C-shaped guide 138 to the second linear guide 137.

[0081] In some embodiments, as shown in the appendix Figure 1 As shown, the distance between adjacent clamping assemblies 7 on chain 134 is half the circumference of sprocket 132. The distance between adjacent clamping assemblies 7 is also the distance between the front and rear molds. For the second chain conveyor 52, since it conveys grouted molds, when the clamping assembly 7 containing the grouted mold moves to the front end of the third frame 51, it will cause the grouted mold to tilt, thereby dumping the excess slurry in the mold. When the distance between adjacent clamping assemblies 7 on chain 134 is half the circumference of sprocket 132, the slurry dumped from the later mold will not fall onto the earlier mold, thus avoiding contamination of the earlier mold.

[0082] In some embodiments, as shown in the appendix Figure 5As shown, the first lifting mechanism 21 includes a first servo motor 211, a transmission shaft 212, and a guide mechanism 213. The first servo motor 211 is mounted on the first frame 11, and its output end is connected to the middle of the transmission shaft 212. The transmission shaft 212 is rotatably mounted on the first frame 11, and both ends of the transmission shaft 212 are provided with eccentric cams 214. The eccentric cams 214 abut against the rollers 215 located at the bottom of the first powered roller conveyor 2. The guide mechanism 213 includes a guide rod 2131 located at the bottom of the first powered roller conveyor 2 and a guide sleeve 2132 located on the first frame 11. The guide sleeve 2132 is fitted onto the guide rod 2131. The first servo motor 211 drives the eccentric cams 214 to cooperate with the rollers 215 at the bottom of the first powered roller conveyor 2, thereby raising and lowering the first powered roller conveyor 2. The cooperation of the guide rod 2131 and the guide sleeve 2132 makes the raising and lowering of the first powered roller conveyor 2 more stable.

[0083] In some embodiments, as shown in the appendix Figure 6 As shown, the second lifting mechanism 35 is a worm gear jack. The lead screw of the worm gear jack is connected to the top of the grouting gun 32. The worm gear jack provides stable lifting and relatively accurate lifting height.

[0084] In some embodiments, as shown in the appendix Figure 7-8As shown, the third lifting mechanism 61 includes a support frame 611 and a support cylinder 612. The support frame 611 is mounted on the third frame 51. Both sides of the support frame 611 are hinged to the third powered roller conveyor 6 via a first connecting rod 613 and a second connecting rod 614. One end of the support cylinder 612 is hinged to the third frame 51, and the other end is hinged to the left end of the third powered roller conveyor 6, enabling the third powered roller conveyor 6 to move synchronously up and down and left and right. Driven by the support cylinder 612, and guided by the connection of the first connecting rod 613 and the second connecting rod 614, the third powered roller conveyor 6 can move synchronously up and down and left and right. Specifically, the mold clamped on the clamping assembly 7 at the second powered roller conveyor 4 is relatively heavy after being grouted by the grouting gun 32. If the third lifting mechanism 61 only drives the third powered roller conveyor 6 to rise, the distance between the third powered roller conveyor 6 and the second powered roller conveyor 4 will be relatively large, and the weight of the clamping assembly 7 with the grouting mold will be relatively heavy. During the process of the second powered roller conveyor 4 pushing the clamping assembly 7 with the grouting mold towards the third powered roller conveyor 6, the clamping assembly 7 is prone to instability and overturning. Therefore, one end of the support cylinder 612 is hinged to the third frame 51, and the other end of the support cylinder 612 is hinged to the left end of the third powered roller conveyor 6. When the support cylinder 612 is driven, the third powered roller conveyor 6 rises while moving from left to right, approaching the second powered roller conveyor 4, thereby catching the clamping assembly 7 with the grouting mold and ensuring that the clamping assembly 7 with the grouting mold moves stably from the second powered roller conveyor 4 to the third powered roller conveyor 6. Afterwards, the third powered roller conveyor 6 descends while resetting from right to left.

[0085] It should be noted that the height of the second powered roller conveyor 4 is higher than that of the first powered roller conveyor 2 and the third powered roller conveyor 6. Thus, through the first lifting mechanism 21, the height of the first powered roller conveyor 2 is made to be the same as that of the second powered roller conveyor 4, which facilitates the movement of the clamping assembly 7 from the first powered roller conveyor 2 to the second powered roller conveyor 4. Through the third lifting mechanism 61, the height of the third powered roller conveyor 6 is made to be the same as that of the second powered roller conveyor 4, which facilitates the movement of the clamping assembly 7 from the second powered roller conveyor 4 to the third powered roller conveyor 6.

[0086] In some embodiments, as shown in the appendix Figure 11 , 14As shown, the clamping mechanism 72 includes a base plate 721, a vertical rod 723, and a clamping unit 724. The base plate 721 is fixed on the support plate 71. A positioning protrusion 722 is provided on the upper end face of the base plate 721, and a positioning groove is provided on the bottom of the mold. The positioning protrusion 722 cooperates with the positioning groove, and the clamped mold is stably fixed on the base plate 721. The vertical rod 723 is vertically fixed on the base plate 721 and is located near one edge of the base plate 721. The clamping unit 724 is slidably connected to the vertical rod 723. The clamping unit 724 includes a movable sleeve 7241, a pressure arm 7245, a locking piece 7243, and a spring 7244. The movable sleeve 7241 is slidably fitted onto the vertical rod 723. The interior of the movable sleeve 7241 has a cavity 7242 with an opening at one end. One end of the pressure arm 7245 is slidably fitted onto the vertical rod 723. 23 is fixedly connected to the upper end of the movable sleeve 7241. The other end of the pressure arm 7245 is located above the positioning protrusion ring 722. One end of the locking plate 7243 is sleeved on the upright 723 and fixedly connected in the cavity 7242. The other end of the locking plate 7243 extends out of the cavity 7242. The spring 7244 is slidably sleeved on the upright 723. The upper end of the spring 7244 abuts against the top wall of the cavity 7242, and the lower end of the spring 7244 abuts against the locking plate 7243. Specifically, the mold is placed on the base plate 721, and one end of the pressure arm 7245 is slid down to the top surface of the mold. At this time, since the other end of the locking piece 7243 protruding from the cavity 7242 is suspended, under the pressure of the spring 7244, the locking piece 7243 tilts and deforms and presses against the upright 723. In this way, the locking piece 7243 and the upright 723 are rigidly pressed together, forming static friction. The static friction is further transmitted to the pressure arm 7245 and restricts the sliding of the pressure arm 7245, thereby making the pressure arm 7245 press the mold tightly.

[0087] In some embodiments, as shown in the appendix Figure 14 As shown, at least two uprights 723 are provided, each with a clamping unit 724. The two uprights 723 are spaced apart and positioned opposite each other on the base plate 721, and the same connecting block 7246 is slidably fitted onto both uprights 723. The two ends of the connecting block 7246 are respectively fixedly connected to the bottom of the movable sleeves 7241 of the two clamping units 724. The movable sleeves 7241 on the two uprights 723 are connected by the same connecting block 7246, maintaining the stability of static friction. Furthermore, the two pressure arms 7245 press against the mold 15, which can more firmly fix the mold 15.

[0088] It should be noted that, as shown in the attached document Figure 1-2 As shown, the ceramic green body production line also includes:

[0089] The fourth powered roller conveyor 8 is mounted vertically on the third frame 51 via a fourth lifting mechanism 81. Because the distance between the fourth powered roller conveyor 8 and the fifth powered roller conveyor 10 is relatively large, the clamping assembly 7, which carries the blank forming mold, is prone to instability and tipping over during the process of moving it from the fourth powered roller conveyor 8 to the fifth powered roller conveyor 10. However, the clamping assembly 7 carrying the blank forming mold is heavy, and the blank cannot be violently shaken. Therefore, the mechanical structure of the fourth lifting mechanism 81 is consistent with that of the third lifting mechanism 61. When the support cylinder 612 is driven, the fourth powered roller conveyor 8 rises while moving from left to right, approaching the fifth powered roller conveyor 10. This ensures that the clamping assembly 7 carrying the blank forming mold moves stably from the fourth powered roller conveyor 8 to the fifth powered roller conveyor 10.

[0090] And in the front and back directions, as shown in the appendix Figure 1-2 As shown, the fourth lifting mechanism 81 is located behind the third lifting mechanism 61. That is, after the third power roller conveyor 6 transmits the clamp assembly 7 containing the grouting mold to the second chain conveyor 52, the clamp assembly 7 containing the grouting mold moves clockwise around the third frame 51 to the fourth power roller conveyor 8 through the second chain conveyor 52. At this time, the grouting mold becomes a blank forming mold.

[0091] As attached Figure 9-13 As shown, the clamp assembly release device 9 is located between the wet mold drying device 1 and the blank forming device 5, and in the front-rear direction, it is located behind the dry mold grouting device 3. It includes a fourth frame 91 and a release mechanism 92. The release mechanism 92 is used to release the blank forming mold from the clamp assembly 7. The number of release mechanisms 92 can be determined according to the number of molds. The release mechanism 92 is vertically movable on the fourth frame 91 via a fifth lifting mechanism 925. The fifth lifting mechanism 925 includes a second servo motor 9251, a column 9252, and a mounting box 9253. The mounting box 9253 is installed on the top of the fourth frame 91. The column 9252 passes through the mounting box 9253 and is connected to the mounting box 9253 through the first sliding mechanism. The first sliding mechanism is a slider and a slide rail. The bottom end of the column 9252 is fixedly connected to the loosening mechanism 92. The second servo motor 9251 is installed on the side wall of the mounting box 9253. The output end of the second servo motor 9251 is provided with a gear 9254. The gear 9254 meshes with the rack 9255 fixed on the column 9252, so that the loosening mechanism 92 can be driven to rise and fall through the fifth lifting mechanism 925.

[0092] For details, see attached. Figure 12-13As shown, the loosening mechanism 92 includes a mounting plate 921, a locking plate pulling unit 923, and a positioning cylinder 924. The mounting plate 921 is fixed to the bottom of the column 9252, and the mounting plate 921 has a clearance hole 922 for cooperating with the column 723. The locking plate pulling unit 923 includes a pull plate 9231 and a front-to-back moving cylinder 9232. The pull plate 9231 has a notch 9233 for cooperating with the column 723. The pull plate 9231 has a first pad 9234 and a second pad 9235 near the notch 9233. The first pad 9234 can support the end of the locking plate 7243 located outside the cavity 7242. The second pad 9235 can support the connecting block 7246. The upper end of the pull plate 9231 passes through the travel limit port 9236 of the mounting plate 921 and is connected to the mounting plate 921 through a second sliding mechanism. The second sliding mechanism is a slider cooperating with a slide rail. The front and rear moving cylinder 9232 is mounted on the mounting plate 921, and the output end of the front and rear moving cylinder 9232 is fixedly connected to the upper end of the pull plate 9231.

[0093] The specific operation is as follows: The fifth lifting mechanism 925 drives the loosening mechanism 92 to descend, causing the mounting plate 921 and the locking plate pulling unit 923 to descend. At this time, the upright 723 is inserted into the clearance hole 922 of the mounting plate 921. At the same time, the forward and backward moving cylinder 9232 drives the notch 9233 of the pulling plate 9231 to rest against the upright 723. The first pad 9234 is located below the end of the locking plate 7243 outside the cavity 7242, and the second pad 9235 is located below the connecting block 7246. The fifth lifting mechanism 925 drives the loosening mechanism 92 to rise, causing the first pad 9234 to support the end of the locking plate 7243 outside the cavity 7242. The locking plate 7243 is in a horizontal state and loses the static friction between it and the upright 723. The movable sleeve 7241 loses the static friction between it and the upright 723. The second pad 9235 supports the connecting block 7246, thereby driving the pressure arm 7245 to detach from the top surface of the blank forming mold.

[0094] Furthermore, the positioning cylinder 924 is mounted on the mounting plate 921. The output end of the positioning cylinder 924 passes through the mounting plate 921 and is located above the other end of the pressure arm 7245, which is away from the upright 723. When the second pad 9235 supports the connecting block 7246, the pressure arm 7245 may tilt, causing it to press against the upright 723. Therefore, the output end of the positioning cylinder 924 drives and abuts against the other end of the pressure arm 7245 to keep the pressure arm 7245 horizontal, reducing the static friction between it and the upright 723 and facilitating the release of the clamping mechanism 72.

[0095] It should be noted that during the process of loosening the clamping mechanism 72, the gripper and finger cylinder installed on the fifth power roller conveyor 10 drive the gripper to clamp the base plate 721 of the clamping mechanism 72, thereby keeping the entire clamping assembly 7 stable.

[0096] After the clamping mechanism 72 is released, the blank forming mold can be removed manually or by machine, the blank forming mold can be opened, the blank can be taken out, and the mold can be put back in its original position so that the clamping mechanism 72 continues to clamp the mold. At this time, the mold is a wet mold.

[0097] Fifth powered roller conveyor 10, as attached Figure 2 , 9 As shown, the fifth powered roller conveyor 10 is disposed on the fourth frame 91 and located below the loosening mechanism 92. The fifth powered roller conveyor 10 is used to convey the clamp assembly 7 containing the wet mold.

[0098] The sixth powered roller conveyor 14, as attached. Figure 1-2 As shown, the sixth power roller conveyor 14 is mounted on the first frame 11 and can be moved up and down via the sixth lifting mechanism 141. The mechanical structure of the sixth lifting mechanism 141 is the same as that of the first lifting mechanism 21, and in the front-back direction, the sixth lifting mechanism 141 is located behind the first lifting mechanism 21.

[0099] In the front-to-back direction, the fourth powered roller conveyor 8, the fifth powered roller conveyor 10, and the sixth powered roller conveyor 14 are aligned to facilitate the transition of the clamping assembly 7 containing the mold from left to right. The fourth powered roller conveyor 8 can move the clamping assembly 7 containing the blank forming mold from left to right onto the fifth powered roller conveyor 10. At the fifth powered roller conveyor 10, the clamping assembly 7 is released by the clamping assembly releasing device 9, and the blank is removed from the blank forming mold, becoming a wet mold. The fifth powered roller conveyor 10 can move the clamping assembly 7 containing the wet mold from left to right onto the sixth powered roller conveyor 14. The entire process, through automated mechanical operation, greatly reduces manual operation, thereby improving production efficiency.

[0100] In summary, the production process of this invention is as follows:

[0101] As attached Figure 1-2As shown, the clamping assembly 7 containing the dry mold is lifted by the first lifting mechanism 21 and placed against the first powered roller conveyor 2. The first powered roller conveyor 2 transports the clamping assembly 7 containing the dry mold from right to left to the second powered roller conveyor 4. Grout is injected into the dry mold by the dry mold injection device 3, transforming it into a grout-injected mold. The second powered roller conveyor 4 transports the clamping assembly 7 containing the grout-injected mold from right to left to the third powered roller conveyor 6. The clamping assembly 7 containing the grout-injected mold is lowered by the third lifting mechanism 61 and transferred to the second chain conveyor 52 of the blank forming device 5. The second chain conveyor 52 moves the clamping assembly 7 containing the grout-injected mold clockwise around the third frame 51, undergoing grouting and forming processes. The grout-injected mold becomes a blank forming mold, and the clamping assembly 7 containing the blank forming mold is transferred to the fourth powered roller conveyor 8. The fourth lifting mechanism 81 raises the fourth powered roller conveyor 8, which supports the clamping assembly 7 containing the blank forming mold. The fourth powered roller conveyor 8 transports the clamping assembly 7 containing the blank forming mold from left to right to the fifth powered roller conveyor 10. The clamping assembly 7 containing the blank forming mold is released by the clamping assembly releasing device 9, so that the blank can be removed manually or by machine. At this time, it becomes a wet mold. The fifth powered roller conveyor 10 transports the clamping assembly 7 containing the wet mold to the sixth powered roller conveyor 14. The sixth lifting mechanism 141 lowers the clamping assembly 7 containing the wet mold, which stops on the first chain conveyor 13 of the wet mold drying device 1. The first chain conveyor 13 moves the clamping assembly 7 containing the wet mold counterclockwise around the first frame 11. After being dried by the drying mechanism 12, the wet mold is dried into a dry mold.

[0102] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
