Technical Field
[0001] This invention relates to a multi-head slurry injection production line for ceramic blanks. Background Technology
[0002] In existing technologies, the manufacturing of ceramic blanks is generally semi-automated. The main workflow is as follows: the operator places the molds one by one on the conveyor belt; when the mold is sent to the bottom of the injection head, the injection head injects slurry into the mold through the injection hole; then the operator removes the mold and lets it stand; after the slurry in the mold has initially solidified, the operator flips the mold to pour out the excess slurry, and lets it stand again; until the slurry in the mold has formed, the operator opens the mold and removes the ceramic blank to demold; after demolding, the mold is air-dried or oven-dried, and the dried mold can be reused; It is easy to see from the above description that the manufacturing method still requires a lot of manual labor, the operators have a high workload and low automation efficiency. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-head slurry injection production line that can realize the automated continuous manufacturing of ceramic blanks.
[0004] The technical solution of the present invention is: a multi-head slurry injection production line for ceramic blanks, comprising a left conveyor belt, a right conveyor belt, a mold drying mechanism, a multi-head slurry injection mechanism, a slurry pouring mechanism, a turning mechanism, an elastic belt transfer mechanism, and a demolding worktable; Both the left and right conveyor belts are equipped with multiple rows of molds; The right conveyor belt consists of a first right conveyor belt and a second right conveyor belt; The mold drying mechanism includes a drying chamber with open ends, through which the first right conveyor belt passes; The multi-head grouting mechanism includes a rotatable grouting platform and multiple grouting heads arranged above one side of the grouting platform. The grouting platform has four sets of rotating turntables arranged in an array. The top of the mold has a bowl-shaped grout guide port, which is connected to the grouting port of the mold. When grouting, one set of the four turntables is located below each grouting head. Each grouting head is eccentrically set with the grouting port of the corresponding mold. Each turntable drives the mold to rotate while grouting. The first right conveyor belt and the second right conveyor belt are respectively located in front of and behind the grouting platform. A first lifting and lowering robotic arm assembly is connected above the grouting platform and moves back and forth. The first robotic arm assembly, in coordination with the rotation of the grouting platform, transfers the mold from the first right conveyor belt to the grouting platform or from the grouting platform to the second right conveyor belt. The pouring mechanism includes a tank, a pouring conveyor belt disposed above the tank, a support disposed above the pouring conveyor belt, and a second robotic arm assembly and a third robotic arm assembly respectively connected to both sides of the support. The second robotic arm group transfers the mold on the second right conveyor belt and flips it over to secure it onto the pouring conveyor belt; the third robotic arm group transfers the mold secured on the pouring conveyor belt to the left conveyor belt. The left conveyor belt consists of a first left conveyor belt, a second left conveyor belt, and a third left conveyor belt; The first left conveyor belt has a long groove in the middle corresponding to the guide port of each inverted mold. The second left conveyor belt and the third left conveyor belt are located in front of and behind the flipping mechanism, respectively. The flipping mechanism includes a frame and a fourth robotic arm group set in the frame. The fourth robotic arm group picks up the mold from the second left conveyor belt, flips the mold upright, and transfers it to the third left conveyor belt. The mold remains in a snapped state when it is located on the first left conveyor belt and the second left conveyor belt; The elastic band transfer mechanism is located above the end of the first right conveyor belt and the third left conveyor belt away from the pouring mechanism. The elastic band transfer mechanism includes a frame and a fifth mechanical arm group that moves left and right on the frame. The mechanical arm in the fifth mechanical arm group can be raised and lowered. The mechanical arm is also provided with four openable and closeable claws. The middle part of the mold is provided with a groove corresponding to the elastic band. The outer side of the mold is also provided with a clearance groove corresponding to each claw. The demolding workbench is located at the end of the third left conveyor belt away from the pouring mechanism.
[0005] Furthermore, the drying chamber is equipped with heating elements or hot air outlets evenly distributed inside. Multiple internal drying mechanisms for the molds are also vertically connected to the top of the drying chamber. Each internal drying mechanism includes an inverted frustum-shaped air guide hood and an air suction pipe fixed at one end inside the air guide hood and coaxially arranged with it. The air outlet of the air guide hood is positioned downwards. A hot air blower is connected to the outside of the air guide hood via a connecting pipe. The air suction pipe consists of a diatomaceous earth shell and a cylindrical heating core disposed inside the diatomaceous earth shell. The upper end of the air suction pipe is connected to a negative pressure blower via a connecting pipe. When the internal drying mechanism for the molds is working, the air guide hood is positioned close to the slurry inlet of the mold. The air suction pipe is inserted into the mold through the slurry inlet. The bottom of the air suction pipe maintains a distance from the bottom of the mold hole inside the mold, and the peripheral wall of the air suction pipe maintains a distance from the peripheral wall of the slurry inlet. The hot air blown out by the air guide hood enters the mold through the gap between the air suction pipe and the slurry inlet and is then discharged through the air suction pipe, thus rapidly drying the inside of the mold in conjunction with the moisture absorption capacity of the diatomaceous earth.
[0006] Specifically, the heating core is a cylindrical porous copper core, and the diatomaceous earth shell covers the heating core and fills the holes on the copper core.
[0007] Furthermore, the second robotic arm assembly includes a movable frame that moves back and forth within a support, a rotating frame that moves up and down on the movable frame, and a second robotic arm fixed on the rotating frame.
[0008] Furthermore, the fourth robotic arm assembly consists of a lifting frame, a rotating frame mounted on the lifting frame, and a fourth robotic arm connected to the rotating frame.
[0009] Furthermore, a baffle is also connected to the end of the third left conveyor belt away from the pouring mechanism, and when the baffle is lowered, it aligns with the mold on the third left conveyor belt.
[0010] Furthermore, a positioning plate is provided at the end of the first right conveyor belt away from the pouring mechanism, and a positioning groove corresponding to the mold is provided at the front end of the positioning plate.
[0011] Furthermore, an arc-shaped conveyor belt is provided between the third left conveyor belt and the demolding workbench, and the demolding workbench is located between the ends of the arc-shaped conveyor belt and the first right conveyor belt.
[0012] Furthermore, the grouting platform consists of a base, a servo motor, and a grouting platform body rotatably connected to the base, with the servo motor driving the grouting platform body to rotate.
[0013] Preferably, each set of turntables includes two turntable bodies, and the bottom of the grouting platform body is provided with a drive motor corresponding to each turntable body. Two rows of molds are respectively provided on the first right conveyor belt, the second right conveyor belt, the first left conveyor belt, the second left conveyor belt and the third left conveyor belt.
[0014] The beneficial effects of this invention are: it enables automated continuous manufacturing of ceramic blanks with a reasonable layout; it can simultaneously perform slurry injection operations on two or more sets of molds, thereby saving labor and effectively improving processing efficiency. The invention also features a specially designed internal drying mechanism for the mold. By spraying and absorbing hot air simultaneously, hot air passes quickly through the mold, which, combined with the moisture absorption capacity of diatomaceous earth, effectively dries the inside of the mold, allowing the inside and outside of the mold to dry at the same time. During the lifting and lowering process of the internal drying mechanism, the diatomaceous earth shell rapidly expels moisture under the action of the internal heating core and airflow, thus maintaining its optimal moisture absorption capacity. The mold was improved by setting a clearance groove to cooperate with the fifth robotic arm to release and bind the elastic band, and the groove corresponding to the elastic band is also used for positioning the gripper on other robotic arms. An elastic band transfer mechanism was designed to enable the quick exchange of elastic bands between the mold to be demolded and the mold that has already been demolded. A mold drying mechanism is set up upstream of the multi-head grouting mechanism to quickly dry the mold, avoiding the phenomenon of ceramic blank bubbles and difficulty in demolding caused by mold dampness. Compared with the air drying of mold in the existing technology, it is beneficial to improve processing efficiency. The multi-head grouting mechanism is equipped with a rotatable grouting platform that works with the first robotic arm to transfer two or more molds simultaneously. Multiple grouting heads simultaneously grout the mold located below. During the grouting process, the grouting holes of each grouting head and the mold are eccentrically set to pour the slurry onto the slurry guide port. The rotation of the mold causes the slurry on the pouring port to flow into the mold in a vortex shape, which can avoid the generation of air holes on the ceramic blank. The second robotic arm of the pouring mechanism transfers the mold on the second right conveyor belt and flips it to be placed on the pouring conveyor belt. During the flipping process, most of the excess mud in the mold is poured out with the tilt of the mold when it is flipped, and a small amount of residual mud is poured out with the placed mold during the conveying process of the pouring conveyor belt. The mold output by the pouring mechanism is inverted and continued to be conveyed on the first left conveyor belt and the second left conveyor belt to avoid slurry accumulation in the mold. Finally, it is flipped right-side up by the flipping mechanism and waits for demolding, which can ensure the quality of the ceramic blank. Attached Figure Description

[0017] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0018] Combination Figure 1-8 As shown, a multi-head slurry injection production line for ceramic blanks includes a left conveyor belt, a right conveyor belt, a mold drying mechanism 1, a multi-head slurry injection mechanism 2, a slurry pouring mechanism 3, a flipping mechanism 4, an elastic belt transfer mechanism 5, and a demolding worktable 6. Both the left and right conveyor belts are equipped with multiple rows of molds 7; The right conveyor belt consists of a first right conveyor belt 8 and a second right conveyor belt 9; The mold drying mechanism 1 includes a drying chamber with open ends, through which the first right conveyor belt 8 passes; The purpose of setting up the drying chamber is to quickly dry the mold 7 after demolding and reduce the moisture inside the mold 7; The multi-head grouting mechanism 2 includes a rotatable grouting platform 10 and multiple grouting heads 11 arranged above one side of the grouting platform 10. The grouting platform 10 has four sets of rotatable turntables 12 arranged on it. The top of the mold 7 has a bowl-shaped grout guide port 13, which is connected to the grouting port 14 of the mold 7. When grouting is performed, one set of the four turntables 12 is located below each grouting head 11. Each grouting head 11 is eccentrically set with the corresponding grouting port 14 of the mold 7. Each turntable 12 drives the mold 7 to rotate while performing grouting. The first right conveyor belt 8 and the second right conveyor belt 9 are respectively arranged in front of and behind the grouting platform 10. A track is also provided above the grouting platform 10. A first lifting and lowering mechanical arm group 15 is connected to the track and moves back and forth. The first mechanical arm group 15, in coordination with the rotation of the grouting platform 10, transfers the mold 7 from the first right conveyor belt 8 to the grouting platform 10 or from the grouting platform 10 to the second right conveyor belt 9. Specifically, every time the grouting platform 10 rotates 90°, a set of turntables 12 rotates to a position below each grouting head 11, and each mold 7 located on the turntables 12 is ready for grouting. When the mold 7 on the turntables 12 is grouting, the first robotic arm group 15 moves to a position above the first right conveyor belt 8 and transfers the mold 7 to another set of turntables 12 on the grouting platform 10 near the first right conveyor belt 8. When the mold 7 located below the grouting head 11 has finished grouting, the grouting platform 10 rotates 90° and rotates the grouting mold 7 to a position near the second right conveyor belt 9. The first robotic arm group 15 moves and transfers the grouting mold 7 to the second right conveyor belt 9. At this time, another set of molds 7 located below the grouting port 14 is grouting, and this cycle continues. It is worth mentioning that each mold 7 rotates under the drive of the turntable 12 to perform grouting. The grouting head 11 and the grouting port 14 of the mold 7 are eccentrically set. The slurry sprayed from the grouting head 11 falls on the bowl-shaped slurry guide port 13 and rotates into the grouting port 14 under the action of centrifugal force, which can avoid the introduction of air during the grouting process and prevent air bubbles from being generated in the slurry inside the mold 7. The pouring mechanism 3 includes a tank 16, a pouring conveyor belt 17 disposed above the tank 16, a support 18 disposed above the pouring conveyor belt 17, and a second robotic arm group and a third robotic arm group respectively connected to both sides of the support 18. The second robotic arm group transfers the mold 7 on the second right conveyor belt 9 and flips it over to be placed on the slurry pouring conveyor belt 17. During the flipping process, excess slurry inside the mold 7 is poured out. The third robotic arm group transfers the mold 7 placed on the slurry pouring conveyor belt 17 to the left conveyor belt. During this process, most of the excess mud in the mold 7 is poured out and falls into the tank 16 during the turning process. When the mold 7 is placed on the mud pouring conveyor belt 17 and conveyed from right to left, the remaining mud is also discharged from the mold 7. The left conveyor belt is composed of a first left conveyor belt 20, a second left conveyor belt 21 and a third left conveyor belt 22; The first left conveyor belt 20 has a long groove 23 in the middle corresponding to the guide port 13 of each inverted mold 7. The second left conveyor belt 21 and the third left conveyor belt 22 are located in front of and behind the flipping mechanism 4, respectively. The flipping mechanism 4 includes a frame and a fourth robotic arm assembly set in the frame. The fourth robotic arm assembly picks up the mold 7 from the second left conveyor belt 21, flips the mold 7 upright, and transfers it to the third left conveyor belt 22. In this structure, the mold 7 is kept in a snapped state when it is on the first left conveyor belt 20 and the second left conveyor belt 21. The purpose is to prevent the slurry from accumulating at the bottom of the mold 7, and the mold 7 can continue to discharge any excess slurry that may exist on the first left conveyor belt 20. The elastic band transfer mechanism 5 is located above the end of the first right conveyor belt 8 and the third left conveyor belt 22 away from the pouring mechanism 3. The elastic band transfer mechanism 5 includes a frame and a fifth mechanical arm group that moves left and right on the frame. The mechanical arm in the fifth mechanical arm group can be raised and lowered. The mechanical arm is also provided with four openable claws. The mold 7 has a groove in the middle corresponding to the elastic band 19. The outer side of the mold 7 is also provided with a clearance groove corresponding to each claw. When the fifth robotic arm group performs the operation of releasing the elastic band 19 on the mold 7 on the third left conveyor belt 22, the claws on the robotic arm are first in a retracted state. The robotic arm is lowered so that the claws are inserted into the inner circumference of the elastic band 19 along the respective clearance grooves. Then the claws are opened so that the elastic band 19 is disengaged from the groove. The robotic arm rises back and drives the elastic band 19 away from the mold 7. When the fifth robotic arm group binds the elastic band 19 to the mold 7 on the first right conveyor belt 8, the robotic arm that has acquired the elastic band 19 is moved above the mold 7. By performing the above operation in reverse, the elastic band 19 can be transferred to the mold 7 on the first right conveyor belt 8. The demolding workbench 6 is located at the end of the third left conveyor belt 22 away from the pouring mechanism 3. The operator opens the mold 7 with the elastic band 19 released from the conveyor belt and demolds the ceramic blank inside the mold 7. After demolding, the operator closes the mold 7 and places it on the first right conveyor belt 8 for repeated operation.
[0019] The beneficial effects of the above structure are: it enables automated continuous manufacturing of ceramic blanks, has a reasonable layout, and can simultaneously perform slurry injection operations on two or more sets of molds 7, which can save labor and effectively improve processing efficiency; Among them, the mold 7 was improved by setting a clearance groove to cooperate with the fifth robotic arm to release and bind the elastic band 19, and the groove corresponding to the elastic band 19 is also used for positioning the gripper on other robotic arms. An elastic band transfer mechanism 5 was designed to enable the quick exchange of elastic bands 19 between the mold to be demolded and the mold that has already been demolded. A mold drying mechanism 1 is set upstream of the multi-head grouting mechanism 2 to quickly dry the mold 7, avoiding the phenomenon of ceramic blank bubbles and difficulty in demolding caused by the dampness of the mold 7. Compared with the air drying of the mold 7 in the prior art, it is beneficial to improve processing efficiency. The multi-head grouting mechanism 2 is equipped with a rotatable grouting platform 10, which works in conjunction with the first robotic arm group 15 to transfer two or more molds 7 at the same time. Multiple grouting heads 11 simultaneously grout the mold 7 located below. During the grouting process, the grouting holes of each grouting head 11 and the mold 7 are eccentrically set to pour the slurry onto the grout guide port 13. The rotation of the mold 7 causes the slurry on the pouring port to be guided into the mold 7 in a vortex shape, which can avoid the generation of air holes on the ceramic blank. The second robotic arm of the pouring mechanism 3 transfers the mold 7 on the second right conveyor belt 9 and flips it to be placed on the pouring conveyor belt 17. During the flipping process, most of the excess mud in the mold 7 is poured out with the tilt of the mold 7 when it is flipped, and a small amount of residual mud is poured out with the placed mold 7 during the conveying process of the pouring conveyor belt 17. The mold 7 output by the pouring mechanism 3 is also inverted on the first left conveyor belt 20 and the second left conveyor belt 21 to continue conveying, so as to avoid the accumulation of slurry in the mold 7. Finally, it is flipped right by the flipping mechanism 4 and waits for demolding, which can ensure the quality of the ceramic blank.
[0020] In another embodiment, combined Figure 1 , Figure 5 and Figure 6As shown, the drying chamber is equipped with heating elements or hot air outlets evenly distributed inside. Multiple internal drying mechanisms for molds are also vertically connected to the top of the drying chamber. Each internal drying mechanism includes an inverted frustum-shaped air guide hood 24 and an air suction pipe 25, one end of which is fixed inside the air guide hood 24 and coaxially arranged with it. The air outlet of the air guide hood 24 is positioned downwards. A hot air blower is connected to the outside of the air guide hood 24 via a connecting pipe. The air suction pipe 25 consists of a diatomaceous earth shell 26 and a cylindrical heating core 27 disposed inside the diatomaceous earth shell 26. The upper end is connected to a negative pressure fan via a connecting pipe. When the internal drying mechanism of the mold is working, the air guide hood 24 is set close to the slurry inlet 13 of the mold 7, and the suction pipe 25 is inserted into the mold 7 through the slurry inlet 14. The bottom of the suction pipe 25 and the bottom of the mold hole inside the mold 7 are kept at a distance, and the peripheral wall of the suction pipe 25 and the peripheral wall of the slurry inlet 14 are kept at a distance. The hot air blown out by the air guide hood 24 enters the mold 7 through the gap between the suction pipe 25 and the slurry inlet 14 and is then discharged through the suction pipe 25. Combined with the moisture absorption capacity of diatomaceous earth, the interior of the mold 7 is dried quickly. In the above structure, hot air is rapidly passed through the interior of mold 7 by spraying and suctioning simultaneously. Combined with the moisture absorption capacity of diatomaceous earth, the interior of mold 7 can be effectively dried, allowing the interior and exterior of mold 7 to be dried at the same time. During the lifting and lowering process of the drying mechanism inside the mold, the diatomaceous earth itself is rapidly dehumidified under the action of the internal heating core 27 and airflow to maintain its optimal moisture absorption capacity.
[0021] Specifically, the heating core 27 is a cylindrical porous copper core, and the diatomaceous earth shell 26 covers the heating core 27 and fills the holes on the copper core. The heating core 27 also provides support for the diatomaceous earth shell 26.
[0022] In another embodiment, such as Figure 2 As shown, the second robotic arm assembly includes a movable frame 28 that is moved back and forth within the support 18, a rotating frame 29 that is lifted and lowered on the movable frame 28, and a second robotic arm 30 fixed on the rotating frame 29. Its workflow is as follows: Initially, the second robotic arm 30 is positioned towards the second right conveyor belt 9 to grip the mold 7 on the second right conveyor belt 9. Then, the second robotic arm 30 rises and swings towards the pouring conveyor belt 17 under the drive of the rotating frame 29. The moving frame 28 drives the second robotic arm assembly to move towards the pouring conveyor belt 17. After the displacement is appropriate, the mold 7 gripped by the second robotic arm 30 is inverted. The second robotic arm 30 descends and places the mold 7 on the pouring conveyor belt 17.
[0023] Since the third robotic arm group does not need to flip the mold 7, but only to transfer the position of the mold 7, the structure of the third robotic arm group is the same as that of the second robotic arm group, except that it does not have a rotating frame 29.
[0024] In another embodiment, such as Figure 4 As shown, the fourth robotic arm assembly consists of a lifting frame 31, a rotating frame 29 mounted on the lifting frame 31, and a fourth robotic arm 32 connected to the rotating frame 29. Its working principle is similar to that of the second robotic arm assembly, except that it cannot move forward or backward, which will not be described in detail here.
[0025] In another embodiment, a baffle is also connected to the end of the third left conveyor belt 22 away from the pouring mechanism 3. When the baffle is lowered, it is used to align the mold 7 on the third left conveyor belt 22 so that the fifth robotic arm group can release the elastic band 19 on the mold 7 in the same row.
[0026] In another embodiment, combined Figure 1 and Figure 7 As shown, the first right conveyor belt 8 is provided with a positioning plate 33 at the end away from the pouring mechanism 3. The front end of the positioning plate 33 is provided with a positioning groove 34 corresponding to the mold 7. The positioning groove 34 facilitates the positioning of the mold 7 after demolding and closing by the operator, so that the molds 7 in the same row are aligned.
[0027] In another embodiment, such as Figure 1 As shown, an arc-shaped conveyor belt 35 is also provided between the third left conveyor belt 22 and the demolding worktable 6. The demolding worktable 6 is located between the ends of the arc-shaped conveyor belt 35 and the first right conveyor belt 8, so that the operator's working position is more reasonable and convenient for operation.
[0028] In another embodiment, such as Figure 3 As shown, the grouting platform 10 consists of a base 36, a servo motor 37, and a grouting platform body rotatably connected to the base 36. The servo motor 37 drives the grouting platform body to rotate.
[0029] Preferred, combined Figure 1 and Figure 3 As shown, each set of turntables 12 includes two turntable bodies. The bottom of the grouting platform 10 body is provided with a drive motor 38 corresponding to each turntable body. Two rows of molds 7 are respectively provided on the first right conveyor belt 8, the second right conveyor belt 9, the first left conveyor belt 20, the second left conveyor belt 21 and the third left conveyor belt 22.
