Description

Technical Field

[0001] The invention relates to the technical field of insulating porcelain sleeve production, in particular to a roughing machine for producing insulating porcelain sleeves of electrical components. Background Art

[0002] Insulating porcelain sleeves are ceramic components used to physically isolate conductors in electrical or electronic circuits. They also provide mechanical support for conductors, provide heat dissipation, and protect the circuit environment. Insulating porcelain sleeves have high resistivity, low high-frequency loss, and high electrical strength, so they are widely used in the installation, support, protection, insulation, isolation, and physical connection of electrical components in the power and electronics industries, such as insulators, insulating bushings, resistor substrates, coil frames, sockets for power tubes, integrated circuit substrates, etc. The production process of insulating porcelain sleeves usually includes raw material preparation, iron removal, mud squeezing, rough smelting, vacuum smelting, sintering, and other steps.

[0003] In the production process of existing insulating porcelain sleeves, the clay is kneaded by a vacuum clay kneading machine after rough kneading. During the previous processing step, the clay contains many bubbles inside, and the vacuum clay kneading machine is used to remove the bubbles from the clay. Sometimes the bubble removal effect is not ideal. Some clays also contain air, which leads to the formation of pores in the later processing, affecting the integrity and continuity of the insulating sleeve. The bubbles can easily cause weak points in the insulating layer, affecting the overall insulation strength. In addition, since rough kneading is a process that requires a long time to process, the clay waiting for subsequent kneading will lose moisture and dry out due to long-term exposure to the air. During the rough kneading process, water needs to be added to ensure the bonding degree of the clay, which brings certain adverse effects to people's use process. In order to solve the deficiencies of the prior art, we propose a rough kneading machine for the production of insulating porcelain sleeves for electrical components. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] The extrusion conveying device 4 includes a conveying box 41, and a cutting assembly 46 is fixedly connected to the left side of the top of the conveying box 41;

[0034] like Figure 3 - Figure 4 As shown, the cutting assembly 46 includes a feed hopper 461, a limit rail 462 and an extrusion motor 463. The feed hopper 461 is fixedly installed on the left side of the top of the conveying box 41. Both ends of the bottom of the feed hopper 461 are fixedly connected to the limit rail 462. The top of the conveying box 41 is fixedly connected to the extrusion motor 463. The inner walls on both sides of the lower end of the feed hopper 461 are provided with sliding grooves 469. The first extrusion roller 464 and the second extrusion roller 465 are rotatably installed at both ends of the feed hopper 461. Both ends of the second extrusion roller 465 and the first extrusion roller 464 are fixedly sleeved. It is connected to a transmission half gear 466, and the second extrusion roller 465 and the first extrusion roller 464 are fixedly sleeved with a second transmission gear 4610 on one side close to the extrusion motor 463, and the outer surfaces of the two second transmission gears 4610 are meshed with each other, and one side of the first extrusion roller 464 is connected to the output end of the extrusion motor 463, and sliding bars 467 are slidably installed inside the limiting rails 462 at both ends, and a cutting wire rope 468 is fixedly connected between the sliding bars 467 at both ends through a connecting piece, and the cutting wire rope 468 is slidably installed inside the sliding groove 469 through the connecting piece.

[0035] By meshing the outer surfaces of the two second transmission gears 4610, when the extrusion motor 463 controls the first extrusion roller 464 to rotate counterclockwise, the first extrusion roller 464 and the second extrusion roller 465 rotate towards each other through the transmission between the two second transmission gears 4610, and the mud entering the conveying box 41 is squeezed to achieve preliminary exhaust of the mud and discharge larger bubbles in the mud.

[0036] Among them, fixed racks are fixedly installed on both sides of the top of the sliding bar 467, and the transmission half gears 466 at both ends of the first squeezing roller 464 and the second squeezing roller 465 have the same tooth direction and are respectively meshed with the fixed racks on both sides of the top of the sliding bar 467.

[0037] During the initial exhaust process, when the transmission half gears 466 with the same tooth direction at both ends rotate in the opposite direction, the transmission half gear 466 at the end of the second squeezing roller 465 meshes with the fixed rack at the top of the left end of the sliding bar 467, pushing the sliding bar 467 to move to the left inside the limiting track 462. When the transmission half gear 466 at the end of the second squeezing roller 465 rotates out of the sliding bar 467, the transmission half gear 466 at the end of the first squeezing roller 464 rotates in the opposite direction and meshes with the fixed rack at the top of the right end of the sliding bar 467, so that the sliding bar 467 drives the cutting wire rope 468 to move to the right inside the sliding groove 469. When the transmission half gear 466 at the end of the first squeezing roller 464 rotates out of the sliding bar 467, the transmission half gear 466 at the end of the second squeezing roller 465 engages with the fixed rack at the top of the left end of the sliding bar 467, pushing the sliding bar 467 to move to the left inside the limiting track 462, so that the cutting wire rope 468 reciprocates between the first squeezing roller 464 and the second squeezing roller 465, and the cutting wire rope 468 is used to cut the mud materials that are stuck together, so as to avoid excessive one-time mud input, which will cause blockage inside the extrusion and conveying device 4 and affect the stirring and conveying of the mud materials.

[0038] like Figure 2 As shown, the first spiral extrusion rod 42 and the second spiral extrusion rod 45 are rotatably installed on both sides of the interior of the conveying box 41, and the first spiral extrusion rod 42 and the second spiral extrusion rod 45 are staggered with each other, and the left ends of the first spiral extrusion rod 42 and the second spiral extrusion rod 45 are fixedly sleeved with the first transmission gear 43, and the outer surfaces of the two first transmission gears 43 are meshed, and one side of the first spiral extrusion rod 42 is fixedly connected with a rotating shaft, and the first spiral extrusion rod 42 is connected to the reduction box 3 through the rotating shaft, and a feed port 44 is opened at the left end of the top of the conveying box 41, and is communicated with the bottom of the cutting assembly 46.

[0039] The first spiral extrusion rod 42 and the second spiral extrusion rod 45 are respectively staggeredly distributed inside the conveying box 41. At the same time, the conveying motor 2 causes the second spiral extrusion rod 45 and the first spiral extrusion rod 42 to rotate towards each other through the reduction box 3. The first spiral extrusion rod 42 and the second spiral extrusion rod 45 rotate and extrude in an staggered manner, so that the material is extruded and mixed, and then conveyed to the inside of the mixing box 5.

[0040] Embodiment 2, as Figure 1 - Figure 5As shown, a roughing machine for producing insulating porcelain sleeves of electrical components, the mixing box 5 includes a wetting box 51 and a water adding spray head 58, the left side of the upper end of the wetting box 51 is connected to the conveying box 41, the top of the wetting box 51 is fixedly connected to the water adding spray head 58, one end of the water adding spray head 58 is fixedly connected to a water pump 55 through a pipeline, the top of the water pump 55 is fixedly connected to a controller 56, one end of the controller 56 is fixedly connected to a water inlet pipe 57, one side of the bottom of the wetting box 51 is fixedly connected to a first kneading motor 52, one side of the first kneading motor 52 is fixedly connected to a torque sensor 53, one side of the torque sensor 53 is fixedly connected to a first stirring blade 54, the first stirring blade 54 is rotatably installed inside the wetting box 51, and the torque sensor 53 is electrically connected to the controller 56.

[0041] When the mud is transported to the interior of the moistening box 51, the first kneading motor 52 controls the first stirring blade 54 to stir the mud inside the moistening box 51 through the torque sensor 53. When the torque sensor 53 senses that the resistance of the stirring of the first stirring blade 54 increases and reaches a certain threshold, the controller 56 and the water pump 55 are controlled to start through an electrical signal, so that the water connected to the water inlet pipe 57 is sprayed out through the water adding spray head 58. Since it takes a certain amount of time for the mud to mix with water, the controller 56 is set to start within a unit time. When the set time is reached, the water supply will be automatically stopped in advance to avoid the mud from being too thin, and automatic water replenishment will be achieved. While keeping the mud at a certain viscosity, it is convenient for the subsequent discharge of bubbles. The water is replenished in a spray form through the water adding spray head 58, which improves the uniformity of the mud mixing and saves the mixing time of the mud.

[0042] Embodiment three, as Figure 1 , Figure 6 - Figure 8 As shown, a roughing machine for producing insulating porcelain sleeves of electrical components, the vacuum mixing assembly 6 includes a cylinder frame 61 and a vacuum box 63, the interior of the cylinder frame 61 is fixedly connected with a fixed pipe 66, a blanking chute 62 is provided on the right side of the top of the cylinder frame 61, the top of the blanking chute 62 is connected to the bottom of the mixing box 5, the right end of the cylinder frame 61 is fixedly connected to the vacuum box 63, a vacuum pump 64 is provided on one side of the vacuum box 63, and a support sleeve 613 is fixedly connected to the upper end of the interior of the vacuum box 63.

[0043] Among them, a partition plate 67 is fixedly connected to the interior of the cylinder frame 61 near one end of the vacuum box 63, a through hole is opened inside the partition plate 67, a limiting groove 610 is opened inside the end of the fixed tube 66 away from the partition plate 67, a first hydraulic cylinder 65 is fixedly connected to the left side of the cylinder frame 61, the first hydraulic cylinder 65 is fixedly installed in the middle of the support frame 1, one end of the first hydraulic cylinder 65 is fixedly connected to a moving frame 611, a fixed screw 612 is fixedly connected to the middle of the right side of the moving frame 611, an extrusion block 69 is fixedly connected to the right side of the moving frame 611, a rotating block 68 is rotatably installed between the partition plate 67 and the support sleeve 613, and cutting scrapers 615 are fixedly connected to both sides of the rotating block 68, and the cutting scraper 615 is rotatably installed on the outer surface of the right side of the partition plate 67.

[0044] When the mud enters the interior of the cylindrical frame 61 through the feeding chute 62, the first hydraulic cylinder 65 controls the movable frame 611 to move toward the direction of the partition plate 67, so that the extrusion block 69 squeezes the internal mud on one side of the partition plate 67, and divides the mud into multiple portions through the through holes inside the partition plate 67. During the extrusion process of the extrusion block 69, the vacuum box 63 is placed in a vacuum state through the vacuum pump 64. At this time, the air pressure inside the air bubbles in the mud is greater than the air pressure inside the vacuum box 63, the bubbles burst, and the air is sucked away in the vacuum box 63, further discharging the air in the mud.

[0045] Among them, the extrusion block 69 is slidably installed inside the cylindrical frame 61, and the length of the extrusion block 69 corresponds to the length of the blanking trough 62. The extrusion block 69 is movably sleeved on the outer surface of the fixed tube 66, the movable frame 611 is slidably installed inside the limit groove 610, the fixed screw 612 is movably sleeved inside the support sleeve 613, and the rotating block 68 is threadedly installed on the outer surface of the fixed screw 612.

[0046] The mud material is divided into thin strips by utilizing the through holes inside the partition plate 67, and through the interaction between the fixed screw 612 and the rotating block 68, the cutting scraper 615 rotates and cuts the mud material extruded from the through holes inside the partition plate 67, so that the mud material is divided into small pieces, which facilitates the discharge of bubbles inside the mud material, makes the mud material more compact, and improves the quality of the mud material.

[0047] like Figure 8 As shown, the discharge device 7 includes a discharge nozzle 71, the bottom of the vacuum box 63 is arc-shaped, and a through groove is opened at the bottom of the vacuum box 63, and is connected to the left side of the top of the discharge nozzle 71, and an electric actuator is arranged at the lower end of the vacuum box 63, and the electric actuator is connected to a switch valve 614, and the switch valve 614 is movably installed inside the through groove, and a second kneading motor 72 is fixedly connected to one side of the lower end of the vacuum box 63, and a second stirring knife 73 is fixedly connected to the output end of the second kneading motor 72, and the second stirring knife 73 is rotatably installed at the lower end of the vacuum box 63.

[0048] Among them, a fixed cover 76 is fixedly connected to the left side of the lower end of the vacuum box 63, a hydraulic pushing cylinder 74 is fixedly connected to the left side of the fixed cover 76, a pushing block 75 is fixedly connected to one side of the hydraulic pushing cylinder 74, the pushing block 75 is movably sleeved inside the discharge nozzle 71, and the pushing block 75 is embedded and installed inside the fixed cover 76.

[0049] The divided clay materials are mixed again inside the vacuum box 63. Mixing and extrusion in a vacuum environment prevents the clay materials from inhaling gas from the air again during the mixing process, thereby effectively improving the compactness of the clay materials and improving the quality of the clay materials.

[0050] It should be noted that the present invention is a roughing machine for producing insulating porcelain sleeves of electrical components. When in use, the raw materials of the insulating porcelain sleeves are squeezed to form mud, and enter the interior of the conveying box 41 through the cutting component 46. At this time, through the transmission between the two second transmission gears 4610, the first extrusion roller 464 and the second extrusion roller 465 rotate in opposite directions to extrude the mud entering the interior of the conveying box 41. When the transmission half gears 466 with the same tooth direction at both ends rotate in opposite directions, the extrusion motor 463 controls the transmission half gear 466 at one end of the first extrusion roller 464 to rotate counterclockwise with the first extrusion roller 464, and the transmission half gear 466 at one end of the second extrusion roller 465 rotates clockwise, and rotates with the sliding The fixed rack at the top left end of the movable bar 467 is meshed, pushing the sliding bar 467 to move to the left inside the limiting track 462. When the transmission half gear 466 at the end of the second squeezing roller 465 rotates out of the sliding bar 467, the transmission half gear 466 at the end of the first squeezing roller 464, which rotates in the opposite direction, is meshed with the fixed rack at the top right end of the sliding bar 467, so that the sliding bar 467 drives the cutting wire rope 468 to move to the right inside the sliding groove 469. The cutting wire rope 468 reciprocates between the first squeezing roller 464 and the second squeezing roller 465, and the cutting wire rope 468 is used to cut the mud materials bonded together, so that the mud materials are broken into small pieces and fall into the inside of the conveying box 41 through the feed port 44.

[0051] The conveying motor 2 rotates the second screw extrusion rod 45 and the first screw extrusion rod 42 toward each other through the reduction box 3, and the first screw extrusion rod 42 and the second screw extrusion rod 45 rotate and extrude alternately, so that the small pieces of mud that fall are extruded and mixed, and at the same time, the mud is driven to be conveyed to the inside of the mixing box 5;

[0052] The water inlet pipe 57 is connected to an external water source, and the first mixing motor 52 controls the first mixing blade 54 to rotate inside the moistening box 51 to mix the mud again. During the mixing process, the resistance of the first mixing blade 54 is sensed by the torque sensor 53. When the torque sensor 53 senses that the resistance of the first mixing blade 54 increases and reaches a certain threshold, the controller 56 and the water pump 55 are controlled to start through an electrical signal, so that the water connected to the water inlet pipe 57 is sprayed out through the water adding spray head 58. Since it takes a certain time for the mud to mix with water, the controller 56 is set to start within a unit time. When the set time is reached, the water supply will be automatically stopped in advance to avoid the mud from being too thin.

[0053] After the mud material is mixed, the first hydraulic cylinder 65 controls the moving frame 611 and the extrusion block 69 to move to the left side, so that the bottom of the blanking chute 62 is opened, and the mud material falls into the inside of the cylinder frame 61 through the blanking chute 62. The first hydraulic cylinder 65 controls the moving frame 611 to move toward the direction of the partition plate 67 again, and through the extrusion block 69, the extrusion block 69 squeezes the internal mud material on one side of the partition plate 67, and through the through hole inside the partition plate 67, the mud material is divided into multiple parts, and in the process of extrusion by the extrusion block 69, the vacuum box 63 is made in a vacuum state through the vacuum pump 64. At this time, the air pressure inside the air bubble in the mud material is greater than the air pressure inside the vacuum box 63, the bubble bursts, and the air is sucked out in the vacuum box 63, and the air in the mud material is further discharged. The divided mud material is mixed again in the vacuum box 63 by the stirring of the second mixing knife 73, so that the mud material is in a vacuum environment when it is mixed, and air is prevented from entering when the mud material is mixed.

[0054] Finally, the switch valve 614 is opened by controlling the electric actuator, so that the mud material passes through the through groove at the bottom of the vacuum box 63 to reach the inside of the discharge nozzle 71, and the push block 75 is squeezed by the hydraulic push cylinder 74 to discharge the mud material from the discharge nozzle 71.
