[0020] Technical effects and advantages of the present invention:

[0021] 1. When the first rotating shaft rotates, it will synchronously drive the needle, the connecting plate and the falling clay to contact each other. The needle can penetrate into the clay to facilitate faster discharge of the air inside the clay. At the same time, the connecting plate and the needle can break the whole clay into multiple small clay segments. The multiple small clay segments are then recombined by squeezing the inner wall of the funnel, so that the moisture and solid particles in the clay are distributed more evenly through decomposition and compounding. At the same time, the decomposition process is also conducive to the discharge of air in the clay.

[0022] At the same time, because the needle is set in a spiral structure, when the clay material collides with the gap of the spiral structure, the clay material will be cut into smaller pieces, so that the air inside the clay material can be discharged. At the same time, when it contacts larger particles, the particles can be broken by colliding with the gap.

[0023] In addition, when the spiral structure comes into contact with the clay, if the clay contains hair or other longer impurities, the puncture needle will rotate and be entangled to the outside of the spiral structure, and can stay on the puncture needle through the blocking block, making it easy for subsequent personnel to clean it.

[0024] 2. In addition, when the connecting plate rotates, it can drive the sweeping plate to rotate, so that the sweeping plate can sweep the mud on the inner wall of the funnel, so that the mud pushes the thrust of the sweeping plate and can be smoothly discharged into the interior of the conveying tube, reducing the adhesion and accumulation of the mud.

[0025] 3. The second rotating shaft can rotate synchronously with the first rotating shaft. The second rotating shaft can transport the mud falling from the funnel through the spiral conveying blade. At the same time, the mud is squeezed and contacted with the inner wall of the conveying cylinder, making the mud closer. At the same time, the squeezed mud can be output. Driven by a motor, other driving structures can be reduced, which can reduce the use cost and save energy.

[0026] 4. While the first rotating shaft is rotating, it can also drive the third gear to rotate. The teeth of the third gear will intermittently mesh with the rack, thereby intermittently driving the baffle to rise. When the teeth of the third gear are not meshing with the rack, the baffle will drop by its own gravity, thereby driving the cutter to cut off the mud segment output from the output port, and at the same time it can play a role in blocking the mud. When the cutting plate is extended, the outer edge of the spiral conveying blade will extend into the material blocking groove, and through contact friction, the mud adhering to the outer edge of the spiral conveying blade can be removed, thereby playing a cleaning role.

[0027] 5. Since the rotation speed of the third gear matches the rotation speed of the first shaft and the second shaft, when the second shaft rotates one circle, the mud material is output through the spiral conveying blade, and the third gear is also driven to rotate one circle at the same time to complete a single cutting work. The cutting speed of the cutter is determined by the rotation speed of the second shaft, and changes adaptively with the rotation speed of the second shaft, that is, the output speed of the mud material.

[0028] 6. By starting the electric push rod, the electric push rod can drive the cutting plate into the through groove, thereby isolating the connection between the conveying cylinder and the funnel, so as to form a closed space inside the conveying cylinder, so as to facilitate the vacuum pump to suck the internal air and reduce air residue. In addition, the pushing in of the cutting plate can cut off the falling mud material, so that the mud material can be divided into multiple parts for separate mud kneading work, thereby reducing the mud kneading pressure of the conveying cylinder.

[0029] 7. By heating the cutter, the stickiness of the mud during cutting can be reduced. At the same time, since one side of the cutter is in close contact with the output port, the heat will be transferred to the output port, which can reduce the stickiness between the mud section and the output port.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The present invention provides Figures 1 to 9 An energy-saving mud kneading machine for producing porcelain insulators shown in the figure comprises a base plate 1, an axis fixer 5 and a fixing seat 31 are respectively arranged at the top of the base plate 1 along the length direction, a conveying cylinder 9 is fixed at the top of the fixing seat 31, a funnel 4 is connected to the top of the conveying cylinder 9, the conveying cylinder 9 is distributed along the length direction of the fixing seat 31, a first rotating shaft 10 and a second rotating shaft 11 are respectively rotatably connected in the funnel 4 and the conveying cylinder 9, a feeding port 3 is connected at the top of the through opening 29, and the top area of ​​the feeding port 3 is larger than the bottom area.

[0042] The clay required for producing porcelain insulators is input from the feed port 3, and falls through the feed port 3 and the funnel 4 in sequence until it falls into the conveying tube 9. The internal structure of the funnel 4 can preliminarily squeeze and stir the falling clay to reduce the air in the clay and relieve the clay kneading pressure of the internal mechanism of the conveying tube 9.

[0043] One end of the first rotating shaft 10 and the second rotating shaft 11 extend out of the corresponding funnel 4 and the conveying cylinder 9 respectively, and the first gear 12 and the second gear 13 are respectively sleeved on the outside of the two extended ends, the first gear 12 and the second gear 13 are meshed with each other, the first rotating shaft 10 and the second rotating shaft 11 are both rotatably connected to the inside of the shaft holder 5, and the first rotating shaft 10 is arranged directly above the second rotating shaft 11, one end of the second rotating shaft 11 extends out of the shaft holder 5, a motor 6 is fixed on the bottom plate 1, and the extended end of the second rotating shaft 11 is fixedly connected to the driving shaft of the motor 6.

[0044] In the actual operation of the present invention, when the motor 6 is started, it can drive the second shaft 11 to rotate. When the second shaft 11 rotates, the first gear 12 and the second gear 13 mesh and rotate, thereby driving the first shaft 10 to rotate.

[0045] Specifically, a plurality of connecting plates 19 are fixed at equal distances on the outside of the first rotating shaft 10, sweeping plates 20 are fixed at the ends of the plurality of connecting plates 19, a needle 18 is arranged between each two connecting plates 19, and the needle 18 is fixed on the outside of the first rotating shaft 10, and a spiral conveying blade 17 is arranged on the outside of the second rotating shaft 11;

[0046] The needle 18 is configured as a spiral structure, and a blocking block 33 is fixedly connected to the top of the needle 18;

[0047] When the first rotating shaft 10 rotates, it will synchronously drive the needle 18, the connecting plate 19 and the falling mud to contact. The needle 18 can penetrate into the interior of the mud, so that the air inside the mud can be discharged faster. At the same time, the connecting plate 19 and the first rotating shaft 10 are distributed at a vertical angle. The multiple rotating connecting plates 19 are equivalent to the role of a blade, which can break the whole piece of mud and decompose it into multiple small mud segments. The multiple small mud segments are then recombined together through squeezing with the inner wall of the funnel 4, so that the moisture and solid particles in the mud are distributed more evenly through decomposition and compounding. At the same time, the decomposition process is also conducive to the discharge of air in the mud.

[0048] At the same time, since the needle 18 is set as a spiral structure, when the clay material collides with the gap of the spiral structure, the clay material will be cut into smaller pieces, so that the air inside the clay material can be discharged. At the same time, when it contacts larger particles, the particles can be broken by colliding with the gap.

[0049] In addition, when the spiral structure contacts the mud material, if the mud material contains hair or other longer impurities, the puncture needle 18 will rotate and be entangled to the outside of the spiral structure, and can stay on the puncture needle 18 through the blocking of the blocking block 33, which is convenient for subsequent personnel to clean.

[0050] In addition, when the connecting plate 19 rotates, the sweeping plate 20 can be driven to rotate, so that the sweeping plate 20 sweeps the mud on the inner wall of the funnel 4, so that the mud pushes the sweeping plate 20 and can be smoothly discharged into the interior of the conveying tube 9, reducing the adhesion and accumulation of the mud.

[0051] And the second rotating shaft 11 can rotate synchronously with the first rotating shaft 10. The second rotating shaft 11 can convey the mud material falling from the funnel 4 through the spiral conveying blade 17. At the same time, the mud material is squeezed and contacted with the inner wall of the conveying tube 9, so that the mud materials are closer together, and the squeezed mud material can be output at the same time.

[0052] By driving with a motor 6, other driving structures can be reduced, which can reduce the use cost and save energy.

[0053] In addition, a vacuum pump 7 is fixed on the bottom plate 1, and the vacuum pump 7 is connected to an air pipe 8. The air pipe 8 is connected to the interior of the conveying tube 9 and the funnel 4 respectively. The vacuum pump 7 can suck the interior of the conveying tube 9 to suck the air discharged from the mud. The specific connection position of the air pipe 8 and the conveying tube 9 and the supporting mechanism when the vacuum pump 7 is used can be selected and arranged according to actual needs.

[0054] It should be noted that, in conjunction with the vacuum pump 7, a detachable sealing cover may be provided at the top of the funnel 4, which is prior art and will not be described in detail.

[0055] At the same time, when the mud material is decomposed in the funnel 4, the suction force generated can absorb the exhausted air.

[0056] A through groove is provided on one side of the connection between the conveying cylinder 9 and the funnel 4, a supporting vertical plate 14 is fixed to one side of the top of the fixed seat 31, an electric push rod 16 is fixed to the side of the supporting vertical plate 14 away from the conveying cylinder 9, the telescopic end of the electric push rod 16 extends out of the supporting vertical plate 14, and a cutting plate 15 is fixed to the extended end of the electric push rod 16, the cutting plate 15 extends into the through groove, and the cutting plate 15 is used to cut off the connection between the conveying cylinder 9 and the funnel 4.

[0057] In the actual operation of the present invention, by starting the electric push rod 16, the electric push rod 16 can drive the cutting plate 15 to enter the through groove, thereby isolating the connection between the conveying cylinder 9 and the funnel 4, so as to form a closed space inside the conveying cylinder 9, so that the vacuum pump 7 can absorb the internal air and reduce air residue. In addition, the pushing in of the cutting plate 15 can cut off the falling mud material, so that the mud material can be divided into multiple parts for separate mud kneading work, thereby reducing the mud kneading pressure of the conveying cylinder 9.

[0058] The other end of the second rotating shaft 11 extends out of the end of the conveying cylinder 9, and a third gear 28 is sleeved on the outer side of the second rotating shaft 11. The third gear 28 is configured as a toothless gear, that is, the number of teeth on the outer side of the third gear 28 is less than half of the outer circle of the third gear 28. Specifically, the number of teeth is set according to needs.

[0059] The end of the conveying cylinder 9 away from the shaft fixer 5 is connected to the output port 22, and the end of the output port 22 away from the conveying cylinder 9 is attached to the baffle 23. A rack 26 is fixed to the top of the baffle 23, that is, when the third gear 28 rotates, it can intermittently mesh with the rack 26.

[0060] The rack 26 is meshed with the third gear 28, a fixed frame 21 is fixed to the outside of the output port 22, a slide rail mechanism is fixed on the fixed frame 21 for the other side of the rack 26 to slide up and down, the slide rail mechanism includes a fixed plate 27, the fixed plate 27 is fixedly connected to the fixed frame 21, and a slide groove 30 is provided on the side of the fixed plate 27 facing the rack 26, a slider is fixed to the side of the rack 26 close to the slide groove 30, the slider is slidably fitted in the inside of the slide groove 30, and a cutter 25 is fixed to the bottom end of the baffle 23.

[0061] A material blocking groove 34 is formed at the bottom end of the cutting plate 15 , and the outer edge of the spiral conveying blade 17 cooperates to extend into the material blocking groove 34 .

[0062] When the cutting plate 15 is extended, the outer edge of the spiral conveying blade 17 will extend into the material blocking groove 34, and the mud material adhering to the outer edge of the spiral conveying blade 17 can be removed through contact friction, thereby playing a cleaning role.

[0063] In the actual operation of the present invention, while the first rotating shaft 10 rotates, it can also drive the third gear 28 to rotate. The teeth of the third gear 28 will intermittently mesh with the rack 26, thereby intermittently driving the baffle 23 to rise. When the teeth of the third gear 28 are not meshed with the rack 26, the baffle 23 descends due to its own gravity, thereby driving the cutter 25 to cut off the mud segments output from the output port 22, and at the same time can play a role in blocking the mud material. The cut mud segments are convenient for subsequent production into insulator blanks.

[0064] And because the rotation speed of the third gear 28 matches the rotation speed of the first rotating shaft 10 and the second rotating shaft 11, when the second rotating shaft 11 rotates one circle, the mud material is output through the spiral conveying blade 17, and the third gear 28 is also driven to rotate one circle at the same time to complete a single cutting operation. The cutting speed of the cutter 25 is determined according to the rotation speed of the second rotating shaft 11, and changes adaptively with the rotation speed of the second rotating shaft 11.

[0065] If a pushing device or other cutting device is used directly, it is also necessary to set corresponding cutting times for mud materials with different output speeds, which saves production costs and reduces energy consumption.

[0066] The cutter 25 is set to be semicircular, and the cutter 25 matches the lower half of the output port 22 to facilitate blocking the mud. A groove is opened inside the baffle 23, and an electric heating tube 24 is arranged in the groove. One side of the cutter 25 fits tightly with the output port 22. By heating, the stickiness between the mud segment and the output port 22 can be reduced.

[0067] A support frame 2 is disposed outside the fixing seat 31 . The bottom end of the support frame 2 is fixed on the bottom plate 1 . A through opening 29 is formed at the top end of the support frame 2 . The through opening 29 is communicated with the top end of the funnel 4 .

[0068] The spiral conveying blades 17 are distributed along the length direction of the conveying cylinder 9 , and the outer surface of the spiral conveying blades 17 has an anti-sticking coating layer.

[0069] A fixing block 32 is protruding from one side of the fixing frame 21 away from the conveying cylinder 9. The baffle 23 is set in an L shape, and the bending part of the baffle 23 is in contact with the top of the fixing block 32. When the baffle 23 drops due to gravity, the fixing block 32 can block the baffle 23 to facilitate the next cutting action.
