Description

Technical Field

[0001] The invention relates to the technical field of conveying, in particular to a clamping and conveying device for graphite crucible forming processing. Background Art

[0002] Graphite crucibles are widely used in metallurgy, casting, chemical industry and other fields. The performance of its forming, processing and conveying equipment directly affects the production efficiency and quality of graphite crucibles. With the continuous advancement of science and technology, various types of graphite crucible forming, processing and conveying equipment have appeared on the market, and these conveying equipment have their own advantages and disadvantages. For example, chain conveyors can improve their conveying capacity by increasing the length and width of the chain, and are suitable for large-scale production and the transportation of large quantities of materials. They can transport materials over longer distances, are not restricted by terrain and space, and can flexibly arrange conveying routes according to production layouts. However, during the use of chain conveyors, the side wall of the graphite crucible is gripped by a clamping structure. The side wall of the graphite crucible is a curved surface, resulting in fewer points of force between the clamping structure and the graphite crucible. The graphite crucible is prone to falling and damage during transportation. If the clamping end of the clamping structure is changed to an arc shape, it cannot adapt to graphite crucibles of different shapes, resulting in higher transportation costs.

[0021] Specifically, the conveying equipment 1, chain conveying structure, telescopic position control component, motion guide component, emptying component, camera 9 and other structures are connected to the human-computer interaction device to realize automatic control. This is an existing public technology and will not be described in detail here.

[0022] Specifically, a forward and reverse motor 5 is fixedly installed on one side of the conveying device 1, and a material blocking frame 6 is fixedly installed on the output end of the forward and reverse motor 5. A pressure sensor 7 fixedly inserted on the material blocking frame 6 is arranged on the movement path of the graphite crucible forming mold 2. When the graphite crucible forming mold 2 conveyed by the conveying device 1 moves against the material blocking frame 6, the pressure sensor 7 is pressurized by the graphite crucible forming mold 2, and the pressure sensor 7 detects the pressure change. The human-computer interaction device receives the feedback of the pressure sensor 7, and the human-computer interaction device controls the conveying device 1 to suspend work, so that the graphite crucible forming mold 2 stays on the demolding station. The lower mold clamping structure and the upper mold clamping structure pre-installed on the outside of the equipment 1 work, the upper mold clamping structure is installed on the top of the conveying equipment 1 through a bracket, the lower mold clamping structure clamps and fixes the lower mold of the graphite crucible forming mold 2, and the upper mold clamping structure absorbs and fixes the upper mold of the rear graphite crucible forming mold 2 and then drives the upper mold to move up. There is sufficient space between the two mounting frames 3 11 in the chain conveying structure, so that the upper mold can move up and away from between the two mounting frames 3 11, providing space for the grasping structure composed of the telescopic positioning control component, the motion guide component, the emptying component, the camera 9 and other structures conveyed by the chain conveying structure to work; In the chain conveying structure, two mounting frames 3 11 are fixedly mounted on the building, two transmission shafts 13 are rotatably mounted between the two mounting frames 3 11, chains 14 are arranged on opposite sides of the two mounting frames 3 11, two sprocket wheels 12 are meshed inside each chain 14, and the sprocket wheels 12 are fixedly mounted on the outer sides of the adjacent transmission shafts 13, and the two chains 14 are supported by the two transmission shafts 13 and the four sprocket wheels 12, and a transmission motor 15 is fixedly mounted on one end of one of the transmission shafts 13, and the transmission motor 15 is fixedly mounted on the side of the chain 14 away from one of the mounting frames 3 11 to control the operation of the transmission motor 15, and the transmission motor 15 drives the two chains 14 to rotate in the same direction through the transmission shaft 13 fixedly mounted at the output end, and the chain conveying structure works; The two mounting frames 4 16 in the telescopic position control assembly are respectively fixedly connected to a certain link in the two chains 14, and two support rods 18 are fixedly installed between the two mounting frames 4 16. The two support rods 18 both penetrate the support frame 17, and the pneumatic cylinder 19 is fixedly inserted on the support frame 17. The piston end of the pneumatic cylinder 19 is fixedly connected to one of the mounting frames 4 16. When the pneumatic cylinder 19 is not working, the chain conveying structure conveys the two mounting frames 4 16 to move left and right, and the support frame 17 moves left and right. And the above-mentioned human-computer interaction device controls the conveying device 1 to suspend work, so that the graphite crucible forming mold 2 stays on the demolding station, and the chain conveying structure works to convey the support frame 17 to the demolding station, and the chain conveying structure suspends work to grab the graphite crucible after demolding. After the graphite crucible forming mold 2 conveyed by the conveying device 1 is demolded, the chain conveying structure drives the grabbing structure to move to a preset position, shortening the graphite crucible processing cycle, and the chain conveying structure and the conveying of the conveying device 1 and the demolding of the graphite crucible forming mold 2 will not cause malicious interference.

[0023] Specifically, a pneumatic cylinder 21 and four telescopic rods 22 are fixedly installed at the bottom of the support frame 17. The piston end of the pneumatic cylinder 21 21 and the piston end of the telescopic rod 22 that can be telescoped up and down are fixedly connected to the support frame 20. After the pneumatic cylinder 21 is controlled to work, the pneumatic cylinder 21 controls the support frame 20 to move up and down, and the pneumatic cylinder 3 23 and the telescopic rod 24 fixedly inserted on the support frame 20 move up and down synchronously, and the clamping member 30 can move up and down. The pneumatic cylinder 21 cooperates with the pneumatic cylinder 3 23 to ensure the up and down movement of the clamping member 30, and ensure that the clamping member 30 can adapt to different graphite crucible processing needs.

[0024] Specifically, a support frame three 25 is fixedly installed between the piston end of the telescopic rod two 24 and the piston end of the pneumatic cylinder three 23, and an air pump 27 is fixedly penetrated through the support frame three 25. An electromagnetic valve 28 is fixedly installed at the air inlet end of the air pump 27. The electromagnetic valve 28 is fixedly connected to an air guide pipe 29 fixedly installed on the outer side of the guide frame 26. Both ends of the guide frame 26 are fixedly connected to the support frame three 25. Therefore, when the pneumatic cylinder three 23 is controlled to control the support frame three 25 to move up and down, the guide frame 26 and the partition plate 33 fixedly installed inside the guide frame 26 and the clamping member 30 fixedly installed at the bottom of the air guide pipe 29 move up and down synchronously to control the up and down position of the clamping member 30 so that the clamping member 30 can enter the graphite crucible.

[0025] Specifically, the guide pipe 232 in the motion guide assembly is fixedly installed on the top of one side of the guide frame 26, and a telescopic tube 242 that can be extended and retracted is fixedly installed at one end of the guide pipe 232, and a one-way valve 43 that can only conduct in one direction is fixedly installed at the bottom end of the telescopic tube 242; a mounting frame 546 is fixedly installed on the top of the support frame 20, and a pneumatic cylinder 545 is fixedly installed inside the mounting frame 546, and a connecting frame 244 is fixedly installed between the piston end of the pneumatic cylinder 545 and the water inlet end of the one-way valve 43, and a fixed bent plate 47 is fixedly installed between the one-way valve 43 and the connecting frame 244. Under the action of the connecting frame 244, the extension or contraction of the mounting frame 546 can drive the one-way valve 43 to move downward or upward, thereby controlling the position of the water inlet end of the one-way valve 43.

[0026] Specifically, the guide pipe 4 36 in the emptying component is fixedly installed on the side of the guide frame 26 away from the guide pipe 2 32, and the guide pipe 5 37 fixedly installed at one end of the guide pipe 4 36 is fixedly installed with a water pump 2 38 at one end. The outer bottom of the telescopic pipe 1 39 fixedly installed at the water inlet end of the water pump 2 38 is fixedly sleeved with a connecting frame 1 41, and the piston end of the pneumatic cylinder 4 40 fixedly installed at the bottom of the shell of the water pump 2 38 is fixedly connected to the connecting frame 1 41, and the telescopic pipe 1 39 can be extended and retracted to control the pneumatic cylinder 4 40 to work. The pneumatic cylinder 40 drives the bottom end of the telescopic tube 39 to move up and down through the connecting frame 41 to control the bottom position of the telescopic tube 39; and the guide pipe 34 is provided at the bottom of the guide pipe 2 32 and the guide pipe 4 36. The guide pipe 34 is fixedly installed at a relatively lower position on the outside of the guide frame 26, and a partition plate 33 is fixedly installed inside the guide frame 26. The partition plate 33 divides the inside of the guide frame 26 into two parts. The two guide pipes 34 are respectively connected to the spaces on both sides of the partition plate 33. The working principle of the crawling structure in this application is as follows: After the support frame 17 stays at the demolding station, the grabbing structure stays at the top of the graphite crucible, and the diversion pipe 14 fixedly installed at the outlet end of the water pump 13 is arranged on the moving path of the moving diversion component, and at this time, the water inlet end of the one-way valve 43 is aligned with the diversion pipe 14; Subsequently, the pneumatic cylinder three 23 is controlled to work to push the support frame three 25 downward, and the clamping member 30 moves downward, and the working extension stroke of the pneumatic cylinder three 23 is calculated and preset in advance according to the processing needs of the graphite crucible, and the bottom end of the clamping member 30 enters the inside of the graphite crucible; when the pneumatic cylinder three 23 stops working, the rubber pad one 31 fixed at the bottom end of the clamping member 30 contacts the inside of the graphite crucible and deforms; after the pneumatic cylinder three 23 stops working, the human-computer interaction device controls the vacuum pump 27 to work, and the vacuum pump 27 extracts air from the inside of the clamping member 30 through the electromagnetic valve 28 and the air guide pipe 29, and a negative pressure is generated inside the clamping member 30 to clamp and fix the graphite crucible. After a period of time, the electromagnetic valve 28 is controlled to stop working and enter a closed state, completing the connection between the chain conveying structure and the graphite crucible, and ensuring the stability of the clamping and fixing; When the pneumatic cylinder 3 23 pushes the support frame 3 25 downward, the pneumatic cylinder 5 45 is controlled to work and extend, the connecting frame 2 44 and the water inlet end of the one-way valve 43 move downward, so that the water inlet end of the one-way valve 43 is inserted into the inside of the guide pipe 1 4. After the pressure sensor 2 51 is fixedly inserted on the connecting frame 2 44 and presses against the top of the guide pipe 1 4, the pressure value detected by the pressure sensor 2 51 changes, and the human-computer interaction device receiving the feedback of the pressure sensor 2 51 controls the pneumatic cylinder 5 45 to stop working, and controls the water pump 1 3 to work to supply water to the inside of the graphite crucible through the guide pipe 1 4, the one-way valve 43, the telescopic tube 2 42, the guide pipe 2 32, the guide frame 26 and the guide pipe 3 34 at the bottom of the guide pipe 2 32. The water seals the deformed rubber pad 1 31 and the graphite crucible to ensure the stability of the clamp 30 fixing the graphite crucible and prevent the graphite crucible from falling.

[0027] After a period of time, when a certain amount of water is stored in the graphite crucible, the water pump 1 3 is controlled to stop working, and the pneumatic cylinder 5 45 is controlled to contract. The pneumatic cylinder 5 45 drives the connecting frame 2 44 and the one-way valve 43 to move upward. The setting of the one-way valve 43 prevents the water inside the telescopic tube 2 42 from flowing out and spilling; then the pneumatic cylinder 3 23 is controlled to work and contract, and the supporting frame 3 25, the clamping member 30 and the graphite crucible adsorbed and fixed by the clamping member 30 move upward; then the chain conveying structure is controlled to work to convey the graphite crucible, so that the graphite crucible leaves the top of the conveying device 1; multiple grabbing structures can be installed on the chain conveying structure, and the chain conveying structure, the multiple grabbing structures cooperate with the conveying device 1, so that the formed graphite crucible can be conveyed away from the top of the conveying device 1 after the graphite crucible forming mold 2 is opened, thereby improving the speed of the graphite crucible forming process.

[0028] After the chain conveying structure conveys the graphite crucible away from the demolding station, the upper mold clamping structure closes the upper mold of the graphite crucible forming mold 2 with the lower mold of the graphite crucible forming mold 2 and then resets it, controls the lower mold clamping structure to release the lower mold of the graphite crucible forming mold 2, and makes the graphite crucible forming mold 2 lose its fixation, controls the forward and reverse motors 5 to work forward, and makes the material blocking rack 6 rotate clockwise to leave the top of the graphite crucible forming mold 2, and the conveying equipment 1 works to convey the graphite crucible forming mold 2 away from the demolding station, and then controls the forward and reverse motors 5 to work reversely, and the material blocking rack 6 rotates counterclockwise, and the material blocking rack 6 and the pressure sensor 7 are reset.

[0029] Two cameras 9 are arranged on the forward path of the grasping structure, wherein a mounting frame 1 8 is fixedly installed between one of the cameras 9 and the mounting frame 3 11 on the same side, and a mounting frame 2 10 is fixedly installed between the other camera 9 and the mounting frame 3 11 on the same side. The camera 9 installed on the mounting frame 1 8 is tilted upward, and the camera 9 is located at the bottom of the graphite crucible to shoot the video of one side and the bottom of the graphite crucible. The camera 9 installed on the mounting frame 2 10 is tilted downward to shoot the situation on the other side of the graphite crucible. The two cameras 9 take a comprehensive picture of the outside of the graphite crucible, and the shooting situation of the camera 9 is fed back to the human-machine interaction. The graphite crucible is provided with a liquid for increasing the sealing between the clamping member 30 and the graphite crucible. If there are cracks or holes in the graphite crucible, the liquid will leak and the leakage will be photographed by the two cameras 9 and fed back to the human-machine interaction device. The human-machine interaction device determines whether the graphite crucible is leaking. The clamping and conveying device composed of a chain conveying structure, a gripping structure, two cameras 9 and other structures provided in the present application uses water to increase the gripping firmness during the conveying process of the graphite crucible to check and determine whether the graphite crucible is leaking, thereby increasing the economic benefit of using the clamping and conveying device.

[0030] A rubber pad 2 35 is fixedly installed at the bottom end of the guide pipe 3 34. After the guide pipe 3 34 enters the inside of the graphite crucible, the rubber pad 2 35 is deformed to ensure that the bottom end of the guide pipe 3 34 is connected with the bottom of the inner cavity of the graphite crucible. After the graphite crucible passes through between the two cameras 9, the pneumatic cylinder 4 40 is controlled to work and extend, so that the connecting frame 1 41 and the bottom end of the telescopic tube 1 39 move downward, so that the bottom end of the telescopic tube 1 39 moves downward close to the preset water tank, and the water pump 2 38 is controlled to work. The water pump 2 38 pumps water from the inside of the graphite crucible through the guide pipe 5 37, the guide pipe 4 36, the guide frame 26, and the guide pipe 3 34 set at the bottom of the guide pipe 4 36 to discharge the water inside the graphite crucible. After a period of time, the pneumatic cylinder 4 40 is controlled to shrink and the connecting frame 1 41 is reset.

[0031] After the inside of the graphite crucible is emptied, if the human-computer interaction device determines that there are cracks or holes in the graphite crucible, the pneumatic cylinder 19 is controlled to drive the support frame 17 to move forward, and the graphite crucible moves forward to the top of the preset recovery conveyor belt. The pneumatic cylinder 3 23 is controlled to push the support frame 3 25 to move downward, and then the solenoid valve 28 is controlled to open, the clamping member 30 is deflated, and the graphite crucible is placed on the top of the recovery conveyor belt. In the present application, the clamping and conveying device can place the graphite crucible at different positions according to whether it is leaking during the conveying process of the graphite crucible, thereby reducing the cost investment required for later sorting.

[0032] In addition, an empty slot three 50 is opened at the bottom of the support frame 20, and the empty slot three 50 is arranged at the top of the vacuum pump 27, and the empty slot three 50 provides space for the up and down movement of the vacuum pump 27; an empty slot one 48 is opened at the top of the support frame 20, and the telescopic tube 2 42 passes through the empty slot one 48, and the empty slot one 48 provides space for the movement of the one-way valve 43; an empty slot two 49 is opened at the bottom of the support frame 20, and the water pump 2 38 is arranged at the top of the empty slot two 49 to provide space for the up and down movement of the water pump 2 38.
