Description

Technical Field

[0001] The present invention relates to the technical field of ceramic production and processing, and particularly relates to a feeding device for ceramic processing. Background Art

[0002] Ceramic production and processing is a process of shaping and firing non-metallic minerals (such as clay) at high temperatures. It encompasses a series of processes from raw material preparation to the finished product coming out of the kiln, including quarrying, clay refining, blank making (such as throwing, die stamping, slip casting, etc.), air drying, trimming, biscuit firing, glazing (dipping, spraying, pouring, etc.), bottom wiping, glaze firing, and kiln discharging, etc.

[0003] In ceramic production and processing, first, a filter press is used to filter the muddy water to obtain a mud cake. Subsequently, workers need to carry the mud cake to the side of the hydraulic extrusion molding machine and manually break the mud cake into small pieces and feed them into the hydraulic extrusion molding machine. Through the hydraulic extrusion action of the machine, the small mud cakes are extruded into mud columns. Then, a cutting tool is used to evenly cut the mud columns into mud blanks of the same size. This series of steps completes the preliminary treatment work of ceramic production and processing.

[0004] When workers put the mud cake into the hydraulic extrusion molding machine, they need to carry the mud cake from the loading vehicle to the molding machine, manually break the mud cake into small pieces and feed them into the molding machine, which requires a lot of physical strength and increases the labor intensity of the workers. This process is not only inefficient, but also workers perform repetitive and high-intensity physical labor for a long time, which is likely to have an adverse impact on the physical health of the workers. Summary of the Invention

[0005] The purpose of the present invention is to provide a feeding device for ceramic processing, which solves the technical problem that workers need to carry the mud cake from the loading vehicle to the molding machine, manually break the mud cake into small pieces and feed them into the molding machine, which requires a lot of physical strength and increases the labor intensity of the workers.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A feeding device for ceramic processing includes a driving slide rail for driving the loading vehicle to move. A handling mechanism for feeding the mud cake into the hydraulic extrusion molding machine is arranged on one side of the driving slide rail. The handling mechanism includes a support assembly. A handling gripper for grasping the mud cake, a transport arm for driving the handling gripper to move, and an electric guide rail for driving the transport arm and the handling gripper to lift and lower are arranged on the support assembly.

[0008] As a further solution of the present invention: The handling gripper includes a fixing plate arranged at the mobile end of the transport arm. Connecting plates are symmetrically and rotatably arranged on both sides of the fixing plate. A handling finger plate for supporting the mud cake is fixedly arranged at the bottom of each group of connecting plates. A pushing component capable of pushing the connecting plates to rotate relative to each other is arranged on the fixing plate.

[0009] As a further solution of the present invention: The pushing component includes an electric telescopic rod fixedly connected to the fixing plate. A push plate is fixedly connected to the extending end of the electric telescopic rod. Rotating plates are fixedly arranged on the adjacent sides of the two groups of connecting plates. A downward pressing chute is opened on the rotating plate. Limit columns that are slidably matched with the downward pressing chute are rotatably arranged on both sides of the push plate.

[0010] As a further solution of the present invention: A pressing plate is horizontally and fixedly arranged at the bottom of the push plate. The extending direction of the pressing plate is the same as that of the handling finger plate. The longitudinal section of the pressing plate is in a T-shaped setting.

[0011] As a further solution of the present invention: The driving slide rail includes a track arranged on the side of the handling mechanism away from the hydraulic extrusion molding machine. Pillars are fixedly arranged at both ends of the track. Gears are rotatably arranged on each group of pillars. A toothed belt is arranged in cooperation with the corresponding gears. A driving device for driving the gears to rotate is fixedly arranged on the pillar. A positioning mechanism for pushing the loading cart to move to the corresponding position is detachably installed on the toothed belt.

[0012] As a further solution of the present invention: There are four groups of the pillars, and they are symmetrically arranged at both ends of the track respectively. There are two groups of the toothed belts, which are respectively arranged in cooperation with the gears on the same side of the track. The positioning mechanism includes an intercepting rod. Tooth blocks that are matched with the toothed belt are fixedly arranged at both ends of the intercepting rod. U-shaped sliders are slidably matched with both ends of the intercepting rod. Springs are arranged in cooperation between the upper ends of each group of U-shaped sliders and the corresponding tooth blocks. The gap between the lower ends of the U-shaped sliders and the tooth blocks is matched with the corresponding toothed belt.

[0013] As a further solution of the present invention: The supporting component includes a base and a supporting column. The supporting column is fixedly arranged on the base. The base is located between the hydraulic extrusion molding machine and the track. The electric guide rail is longitudinally arranged on the supporting column.

[0014] As a further solution of the present invention: The transport arm includes a sliding arm and an extending arm. The sliding arm is connected in cooperation with the electric guide rail. A motor is fixedly arranged at the end of the sliding arm. An extending arm that can be electrically telescopic is fixedly arranged at the output end of the motor. The end of the extending arm is fixedly connected to the fixing plate.

[0015] As a further solution of the present invention: A slope for facilitating insertion between adjacent mud cakes is arranged at the end of the handling finger plate.

[0016] As a further solution of the present invention: Each of the connecting plates is fixedly connected to two sets of handling finger plates.

[0017] Advantages of the present invention:

[0018] 1. In the present invention, when handling the mud cake, the electric guide rail drives the sliding arm to the corresponding height position of the mud cake to be transported. The extension arm extends and drives the handling gripper to move forward, so that the handling finger plates are inserted between adjacent mud cakes. Then the electric guide rail drives the handling gripper to move upward, separating the transported mud cake from the bottom mud cake. The motor drives the extension arm to rotate, and at the same time the extension arm contracts, sending the mud cake directly above the input end of the hydraulic extrusion molding machine. The electric telescopic rod extends and drives the push plate to move downward. The downward movement of the push plate drives the limit post to move downward. The downward movement of the limit post drives one end of the rotating plate to move downward. The downward movement of one end of the rotating plate drives the connecting plate to rotate. The rotation of the connecting plate drives the handling finger plates to rotate around the axis of the connecting plate, weakening the intermediate supporting force of the mud cake. The downward movement of the push plate drives the pressing plate to move downward. The downward movement of the pressing plate squeezes the middle position of the mud cake, breaking the mud cake in half. Then the mud cake falls into the input port of the hydraulic extrusion molding machine under the action of gravity, realizing the automatic feeding operation. Overall, it reduces the input of labor costs, and since the machine does not need to rest due to heavy labor, it can improve the overall feeding efficiency and ensure the production efficiency.

[0019] 2. In the present invention, when feeding is required, the loading vehicle can be pushed onto the track, the positioning mechanism is taken out, the upper end of the U-shaped slider is pressed, the spring contracts, so that the lower end of the U-shaped slider is separated from the tooth block to form a bite. Align the bite with the toothed belt, make the tooth block buckle on the toothed belt, release the U-shaped slider, and the spring pushes the U-shaped slider upward, so that the lower end of the U-shaped slider and the bottom of the tooth block bite the toothed belt, thus realizing the positioning of the intercepting rod. The two driving devices drive the gears on the same side to rotate. The gears drive the toothed belt to move. The toothed belt drives the intercepting rod to move. The intercepting rod pushes the loading vehicle to move. When the loading vehicle is transported to the material-taking position on one side of the support column, the driving device stops running, completing the automatic transportation operation.

The driving device 205 can be a servo system that is electrically connected to each other. A positioning mechanism 4 for pushing the loading vehicle 1 to move to a corresponding position is detachably installed on the tooth belt 204. In this embodiment, as Figure 1 shown, there are four groups of pillars 202, which are symmetrically provided at both ends of the rail 201 respectively. There are two groups of tooth belts 204, which are respectively cooperatively provided on the gears 203 on the same side of the rail 201 for driving the stable operation of the loading vehicle 1.

[0030] The positioning mechanism 4 includes an intercepting rod 401. Tooth blocks 402 that cooperate with the tooth belt 204 are fixedly provided at both ends of the intercepting rod 401. Meshing teeth that cooperate with the tooth belt 204 are provided at the bottom of the tooth block 402. U-shaped sliders 403 are slidably engaged at both ends of the intercepting rod 401. AsFigure 5 As shown, a spring 404 is arranged between the upper end of each U-shaped slider 403 and the corresponding tooth block 402 in a matching manner, and the gap between the lower end of the U-shaped slider 403 and the tooth block 402 is matched with the corresponding tooth belt 204. The spring 404 squeezes the U-shaped slider 403 to move upward, so that the bottom of the U-shaped slider 403 bites the tooth belt 204, thereby realizing the positioning of the intercepting rod 401. The driving device 205 drives the gear 203 on the same side to rotate, the gear 203 drives the tooth belt 204 to move, the tooth belt 204 drives the intercepting rod 401 to move, and the intercepting rod 401 pushes the loading vehicle 1 to move, completing the transportation effect.

[0031] The handling mechanism 5 includes a support assembly, and a handling gripper 505 for grasping the mud cake 3, a transport arm 504 for driving the handling gripper 505 to move, and an electric guide rail 503 for driving the transport arm 504 and the handling gripper 505 to lift and lower are arranged on the support assembly.

[0032] As Figure 3 shown, the handling gripper 505 includes a fixing plate 5051 arranged at the mobile end of the transport arm 504. Connecting plates 5052 are symmetrically and rotatably arranged on both sides of the fixing plate 5051, and handling finger plates 5054 for supporting the mud cake 3 are fixedly arranged at the bottom of each group of connecting plates 5052. A pushing assembly for pushing the connecting plates 5052 to rotate relatively is arranged on the fixing plate 5051. The pushing assembly includes an electric telescopic rod 5053 fixedly connected to the fixing plate 5051. A push plate 5057 is fixedly connected to the extending end of the electric telescopic rod 5053. Rotating plates 5055 are fixedly arranged on the adjacent sides of the two groups of connecting plates 5052. A downward pressure chute 5056 is formed in the rotating plate 5055. Limit posts 5058 that are slidably matched with the downward pressure chute 5056 are rotatably arranged on both sides of the push plate 5057. A pressing plate 5059 is fixedly arranged horizontally at the bottom of the push plate 5057. The extending direction of the pressing plate 5059 is the same as the extending direction of the handling finger plate 5054, and the longitudinal section of the pressing plate 5059 is arranged in a T shape. The extension of the electric telescopic rod 5053 drives the push plate 5057 to move downward. The downward movement of the push plate 5057 drives the limit posts 5058 to move downward. The downward movement of the limit posts 5058 drives one end of the rotating plate 5055 to move downward. The downward movement of one end of the rotating plate 5055 drives the connecting plate 5052 to rotate. The rotation of the connecting plate 5052 drives the handling finger plate 5054 to rotate around the axis of the connecting plate 5052, so that the intermediate supporting force of the mud cake 3 is weakened. The downward movement of the push plate 5057 drives the pressing plate 5059 to move downward. The downward movement of the pressing plate 5059 squeezes the middle position of the mud cake 3, breaking the mud cake 3 into two halves. Then, the mud cake 3 falls to the input port of the hydraulic extrusion molding machine 6 under the action of gravity.

[0033] As Figure 2As shown in the figure, the support assembly includes a base 501 and a support column 502. The support column 502 is fixedly arranged on the base 501. The base 501 is located between the hydraulic extrusion molding machine 6 and the track 201. The electric guide rail 503 is longitudinally arranged on the support column 502. The transport arm 504 includes a sliding arm 5041 and an extension arm 5042. The sliding arm 5041 is cooperatively connected with the electric guide rail 503. The electric guide rail 503 can drive the sliding arm 5041 to move up and down. A motor 5043 is fixedly arranged at the end of the sliding arm 5041. An extension arm 5042 that can be electrically extended and retracted is fixedly arranged at the output end of the motor 5043. The end of the extension arm 5042 is fixedly connected to a fixing plate 5051. When the transport arm 504 transports the mud cake 3, first, the electric guide rail 503 drives the sliding arm 5041 to the corresponding height position of the mud cake 3 to be transported. The extension arm 5042 extends to drive the handling gripper 505 to move forward, so that the handling finger plate 5054 is inserted between adjacent mud cakes 3. Then, the electric guide rail 503 drives the handling gripper 505 to move up, so that the transported mud cake 3 is separated from the bottom mud cake 3. The extension arm 5042 contracts, and the motor 5043 drives the extension arm 5042 to rotate, and the mud cake 3 is sent directly above the input end of the hydraulic extrusion molding machine 6.

[0034] The end of the handling finger plate 5054 is provided with a slope that is convenient for inserting between adjacent mud cakes 3. There are two groups of handling finger plates 5054 fixedly connected to each group of connecting plates 5052, so as to ensure the stability when the mud cake 3 is lifted. A group of photoelectric sensors are arranged on the sliding arm 5041 to detect the height of the mud cake 3 stack. A group of photoelectric sensors are arranged on one side of the support column 502 to detect the position of the loading vehicle 1, which is convenient for positioning the loading vehicle 1.

[0035] The working principle of the present invention: When feeding is required, the loading vehicle 1 can be pushed onto the track 201, the positioning mechanism 4 is taken out, the upper end of the U-shaped slider 403 is pressed, the spring 404 contracts, so that the lower end of the U-shaped slider 403 is separated from the tooth block 402 to form a bite. The bite is aligned with the toothed belt 204, and the tooth block 402 is buckled on the toothed belt 204. The U-shaped slider 403 is released, and the spring 404 pushes the U-shaped slider 403 to move up, so that the lower end of the U-shaped slider 403 and the bottom of the tooth block 402 bite the toothed belt 204, thereby realizing the positioning of the intercepting rod 401. Two groups of driving devices 205 drive the gears 203 on the same side to rotate. The gears 203 drive the toothed belt 204 to move. The toothed belt 204 drives the intercepting rod 401 to move. The intercepting rod 401 pushes the loading vehicle 1 to move. When the loading vehicle 1 is transported to the material-taking position on one side of the support column 502, the driving device 205 stops operating, and the automatic transportation operation is completed;

[0036] When transporting the mud cake 3, the electric guide rail 503 drives the sliding arm 5041 to the corresponding height position of the mud cake 3 to be transported. The extension arm 5042 extends to drive the handling gripper 505 to move forward, so that the handling finger plate 5054 is inserted between adjacent mud cakes 3. Then the electric guide rail 503 drives the handling gripper 505 to move upward, so that the transported mud cake 3 is separated from the bottom mud cake 3. The motor 5043 drives the extension arm 5042 to rotate, and at the same time the extension arm 5042 contracts to send the mud cake 3 directly above the input end of the hydraulic extrusion molding machine 6. The electric telescopic rod 5053 extends to drive the push plate 5057 to move downward. The downward movement of the push plate 5057 drives the limit post 5058 to move downward. The downward movement of the limit post 5058 drives one end of the rotating plate 5055 to move downward. The downward movement of one end of the rotating plate 5055 drives the connecting plate 5052 to rotate. The rotation of the connecting plate 5052 drives the handling finger plate 5054 to rotate around the axis of the connecting plate 5052, weakening the intermediate supporting force of the mud cake 3. The downward movement of the push plate 5057 drives the pressing plate 5059 to move downward. The downward movement of the pressing plate 5059 squeezes the middle position of the mud cake 3 to break the mud cake 3 into two halves. Then the mud cake 3 falls into the input port of the hydraulic extrusion molding machine 6 under the action of gravity, realizing the automatic feeding operation.
