Abstract
Description
Technical Field
[0001] The invention relates to the technical field of alumina powder feeding, and in particular to an automatic feeding device for alumina powder processing. Background Art
[0002] Alumina powder is made from nano-alumina through deep processing. It can be added to the aqueous liquid of various resins to increase the hardness of the resin. Alumina powder is usually white powder with very small particle size.
[0003] At present, when alumina powder is fed into a receiving barrel, it is first fed into the receiving barrel and then blown. However, due to the small particle size of alumina powder, it is easy to scatter, so some alumina powder will float out of the feeding barrel during feeding, which not only pollutes the environment but also causes waste.

[0018] The present invention has the following beneficial effects:
[0019] 1. By setting up a feeding mechanism and starting the motor, the glass hemisphere rotates and rubs against the silk adsorption layer to generate static electricity. After the alumina powder enters the collecting barrel, it will be adsorbed on the surface of the silk adsorption layer under the action of static electricity, thereby preventing the alumina powder from flying around and causing environmental pollution and waste;
[0020] 2. By setting the pump air cavity, the one-way air extraction pipe and the one-way pump air pipe, during the extraction process, the reciprocating sealing sliding of the sliding plug can draw the external hot air into the pump air cavity through the one-way air extraction pipe, and then the hot air will enter the receiving barrel through the one-way pump air pipe, which can heat the alumina powder to make it drier. After the temperature in the receiving barrel increases, it is easier for the silk adsorption layer to generate static electricity, thereby improving the adsorption capacity of alumina powder.
[0021] 3. By setting a blowing mechanism and a trigger mechanism, as more and more alumina powder is adsorbed in the receiving barrel, the weight of the receiving barrel will become larger and larger, and then under the action of gravity, the mounting rod will overcome the elastic force of the fourth spring and slowly slide downward in the vertical slot. When the mounting rod contacts the delay switch, the delay switch will be turned on. At this time, the first electromagnet will be energized to generate magnetism, thereby generating magnetic repulsion, pushing the first magnetic rod into the first slot. At this time, the rotation of the shaft will drive the rotation of the first sleeve, and then drive the rotation of multiple fan blades, so as to blow the material. The alumina powder adsorbed on the surface of the silk adsorption layer will be blown off and then discharged through the discharge pipe, so as to load the material. The delay switch will be disconnected after the delay, and the blowing will stop. This reciprocating process can be used for intermittent loading.
[0022] 4. By setting up a discharge mechanism, when feeding, the second electromagnet will also be energized to generate magnetism, generate magnetic repulsion, and then push the second magnetic rod to move into the second slot. At this time, the shaft will synchronously drive the second sleeve to rotate, and then drive multiple stirring rods to rotate, and hit the alumina powder. Since the alumina powder may clump under the action of static electricity, it can be dispersed by the beating of the stirring rod, thereby preventing the alumina powder from clogging the discharge pipe and affecting the feeding. When the stirring rod rotates, it will collide with multiple rubber rods, causing the rubber rods to vibrate. The vibration will be transmitted to the receiving barrel, and then the alumina powder can be vibrated, making it easier to fall off the silk adsorption layer;
[0023] 5. By setting the first breaking rod, the mounting plate, the third shaft sleeve, the second breaking rod, the first bevel gear, the second bevel gear, the third bevel gear and the rotating rod, after the alumina powder enters the collecting barrel, the filter plate will filter it. If the alumina powder is agglomerated, it will not be able to pass through the filter plate and will stay at the upper end of the filter plate. The rotation of the rotating shaft will drive multiple first breaking rods to rotate, and the rotating shaft will also synchronously drive the first bevel gear to rotate, and then drive the third bevel gear to rotate, thereby driving the second bevel gear to rotate, and driving the third shaft sleeve to rotate. The third shaft sleeve rotates in the opposite direction to the rotating shaft, thereby driving multiple second breaking rods to rotate in the opposite direction. The first breaking rod cooperates with the second breaking rod to break up the alumina powder agglomerates on the filter plate to facilitate its loading. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.
[0032] Reference Figure 1 - Figure 6 , an automatic feeding device for processing alumina powder, comprising a base 1 and a receiving barrel 2;
[0033] The feeding mechanism includes a rotating shaft 3 rotatably connected to the top of the receiving barrel 2, a plurality of fixed rods 4 are fixedly connected to the side wall of the rotating shaft 3, and a glass hemisphere 5 is fixedly connected to the end of each of the plurality of fixed rods 4 away from the rotating shaft 3. A plurality of silk adsorption layers 46 are fixedly connected to the inner wall of the receiving barrel 2, and the glass hemisphere 5 is fitted with the silk adsorption layer 46. A box body 6 is fixedly connected to the side wall of the receiving barrel 2, and a sliding plug 7 is sealingly and slidably connected to the inner wall of the box body 6. The sliding plug 7 divides the interior of the box body 6 into two parts: a pumping chamber 701 and a pump air chamber 702. A one-way pumping pipe 8 is fixedly connected to the inner wall of the pumping chamber 701, and the other end of the one-way pumping pipe 8 is connected to an external silo for storing alumina powder, and the one-way pumping pipe 8 only allows external alumina powder to enter the pumping chamber 701. The pumping chamber 701 is connected to the inside of the receiving barrel 2 through a one-way feeding pipe 9, and the one-way feeding pipe 9 only allows the alumina powder in the pumping chamber 701 to enter the receiving barrel 2.
[0034] The feeding mechanism also includes a cross bar 10 fixedly connected to the side wall of the sliding plug 7, the other end of the cross bar 10 passes through the inner wall of the receiving barrel 2 and is fixedly connected to a semicircular head 11, the side wall of the cross bar 10 is sleeved with a first spring 12, the two ends of the first spring 12 are respectively fixedly connected to the side wall of the sliding plug 7 and the inner wall of the box body 6, a filter plate 15 is fixedly connected to the inner wall of the receiving barrel 2, and a motor 16 is fixedly connected to the upper end of the receiving barrel 2, and the output end of the motor 16 passes through the upper end of the receiving barrel 2 and is fixedly connected to the rotating shaft 3.
[0035] Furthermore, by starting the motor 16, the rotating shaft 3 is driven to rotate, and then the multiple fixed rods 4 are driven to rotate, and then the multiple glass hemispheres 5 are driven to rotate. During the rotation of the glass hemisphere 5, friction will be generated with the silk adsorption layer 46. Since the electron confinement capacity of glass is smaller than that of silk, during the friction process, the glass hemisphere 5 loses electrons, while the silk adsorption layer 46 gains electrons, and then the silk adsorption layer 46 generates static electricity. In addition, during the rotation of the glass hemisphere 5, it will intermittently abut against the semicircular head 11, pushing the semicircular head 11 to move, and in conjunction with the first spring 12, the cross bar 10 will move back and forth, thereby driving the sliding plug 7 to slide back and forth in a sealed manner. Under the action of the sliding plug 7, the alumina powder in the external silo will be drawn into the extraction chamber 701 through the one-way extraction pipe 8, and then the alumina powder in the extraction chamber 701 will enter the receiving barrel 2 through the one-way feeding pipe 9. After the alumina powder enters the receiving barrel 2, it will adhere to the silk adsorption layer 46 under the action of static electricity, thereby preventing the alumina powder from scattering everywhere and causing environmental pollution and waste.
[0036] A one-way exhaust pipe 13 is fixedly connected to the inner wall of the pump air cavity 702, the other end of which is connected to an external device storing hot air, and the one-way exhaust pipe 13 only allows external hot air to enter the pump air cavity 702. The pump air cavity 702 is connected to the inside of the receiving barrel 2 through a one-way pump air pipe 14, and the one-way pump air pipe 14 only allows the hot air in the pump air cavity 702 to enter the receiving barrel 2.
[0037] Furthermore, during the extraction process, the reciprocating sealed sliding of the slide plug 7 can draw external hot air into the pump air chamber 702 through the one-way exhaust pipe 13, and then the hot air will enter the receiving barrel 2 through the one-way pump air pipe 14, which can heat the alumina powder to make it drier. After the temperature in the receiving barrel 2 increases, it is easier for the silk adsorption layer 46 to generate static electricity, thereby improving the adsorption capacity of alumina powder.
[0038] A blowing mechanism is installed on the receiving barrel 2, and the blowing mechanism includes a first sleeve 17 rotatably connected to the top of the receiving barrel 2. The first sleeve 17 is sleeved on the side wall of the rotating shaft 3. A plurality of fan blades 18 are fixedly connected to the side wall of the first sleeve 17. A plurality of ventilation holes 24 are opened at the upper end of the receiving barrel 2.
[0039] The blowing mechanism also includes two first slide grooves 19 symmetrically opened on the side wall of the rotating shaft 3, the inner walls of the two first slide grooves 19 are slidably connected with the first magnetic rod 20, the inner wall of the first sleeve 17 is opened with a plurality of first card grooves 21 cooperating with the first magnetic rod 20, the inner wall of the first slide groove 19 is fixedly connected with the first electromagnet 22, and the second spring 23 is fixedly connected between the inner wall of the first slide groove 19 and the first magnetic rod 20.
[0040] A discharge mechanism is installed on the receiving barrel 2, and the discharge mechanism includes a discharge pipe 25 fixedly connected to the lower end of the receiving barrel 2, a cross plate 26 is fixedly connected to the inner wall of the discharge pipe 25, a second shaft sleeve 27 is rotatably connected to the upper end of the cross plate 26, the lower end of the rotating shaft 3 extends to be arranged in the second shaft sleeve 27, and two second sliding grooves 28 are symmetrically provided on the side wall of the rotating shaft 3, a second magnetic rod 29 is slidably connected to the inner wall of the second sliding groove 28, a plurality of second card grooves 30 cooperating with the second magnetic rod 29 are provided on the inner wall of the second sleeve 27, a second electromagnet 31 is fixedly connected to the inner wall of the second sliding groove 28, and a third spring 32 is fixedly connected between the inner wall of the second sliding groove 28 and the second magnetic rod 29.
[0041] The discharge mechanism further includes a plurality of stirring rods 38 fixedly connected to the side wall of the second sleeve 27 , and a plurality of rubber rods 39 fixedly connected to the inner wall of the discharge pipe 25 .
[0042] A trigger mechanism is installed on the base 1, and the trigger mechanism includes a fixed seat 33 fixedly connected to the upper end of the base 1, a vertical groove 34 is opened at the upper end of the fixed seat 33, and a mounting rod 35 is slidably connected to the inner wall of the vertical groove 34, the receiving barrel 2 is fixedly connected to the side wall of the mounting rod 35, and a fourth spring 36 is fixedly connected between the bottom of the vertical groove 34 and the mounting rod 35.
[0043] The trigger mechanism further includes a time delay switch 37 fixedly connected to the bottom of the vertical slot 34 . The time delay switch 37 , the first electromagnet 22 and the second electromagnet 31 are electrically connected via a wire.
[0044] Furthermore, as more and more alumina powder is adsorbed in the receiving barrel 2, the weight of the receiving barrel 2 will become larger and larger, and then under the action of gravity, the mounting rod 35 will overcome the elastic force of the fourth spring 36 and slowly slide downward in the vertical slot 34. When the mounting rod 35 contacts the delay switch 37, the delay switch 37 will open (the delay switch 37 can remain closed for a period of time after opening and then automatically disconnect). At this time, the first electromagnet 22 is energized to generate magnetism, and then generate magnetic repulsion, pushing the first magnetic rod 20 into the first slot 21. At this time, the rotation of the rotating shaft 3 will drive the first shaft sleeve 17 to rotate, and then drive the multiple fan blades 18 to rotate, thereby blowing the material. The alumina powder adsorbed on the surface of the silk adsorption layer 46 will be blown off and then discharged through the discharge pipe 25, thereby loading the material. The delay switch 37 will disconnect after the delay, and the blowing will stop. This reciprocating process can be used for intermittent loading.
[0045] It is worth mentioning that when loading, the second electromagnet 31 will also be energized to generate magnetism, generating magnetic repulsion, thereby pushing the second magnetic rod 29 to move into the second slot 30. At this time, the rotating shaft 3 will synchronously drive the second sleeve 27 to rotate, and then drive the multiple stirring rods 38 to rotate, so as to hit the alumina powder. Since the alumina powder may clump together under the action of static electricity, it can be dispersed by the beating of the stirring rods 38, thereby preventing the alumina powder from clumping together and blocking the discharge pipe 25, affecting the loading. When the stirring rods 38 rotate, they will collide with the multiple rubber rods 39, causing the rubber rods 39 to vibrate. The vibration will be transmitted to the receiving barrel 2, thereby vibrating the alumina powder, making it easier to fall off from the silk adsorption layer 46.
[0046] A plurality of first breaking rods 40 are fixedly connected to the side wall of the rotating shaft 3, a mounting plate 47 is fixedly connected to the inner wall of the receiving barrel 2, a third shaft sleeve 48 is rotatably connected to the upper end of the mounting plate 47, the rotating shaft 3 and the third shaft sleeve 48 are both arranged through the mounting plate 47, and the third shaft sleeve 48 is sleeved on the side wall of the rotating shaft 3, a plurality of second breaking rods 41 are fixedly connected to the side wall of the third shaft sleeve 48, a first bevel gear 42 is fixedly connected to the side wall of the rotating shaft 3, a second bevel gear 43 is fixedly connected to the side wall of the first shaft sleeve 17, a rotating rod 44 is rotatably connected to the inner wall of the receiving barrel 2, a third bevel gear 45 is fixedly connected to the side wall of the rotating rod 44, and the third bevel gear 45 is meshed with the first bevel gear 42 and the second bevel gear 43, respectively.
[0047] Furthermore, after the alumina powder enters the collecting barrel 2, the filter plate 15 will filter it. If the alumina powder is clumped, it will not be able to pass through the filter plate 15, but will stay on the upper end of the filter plate 15. The rotation of the rotating shaft 3 will drive the multiple first breaking rods 40 to rotate, and the rotating shaft 3 will also synchronously drive the first bevel gear 42 to rotate, and then drive the third bevel gear 45 to rotate, thereby driving the second bevel gear 43 to rotate, and driving the third shaft sleeve 48 to rotate, and the third shaft sleeve 48 rotates in the opposite direction to the rotating shaft 3, thereby driving the multiple second breaking rods 41 to rotate in the opposite direction. The first breaking rod 40 cooperates with the second breaking rod 41 to break up the alumina powder clumps on the filter plate 15 to facilitate its loading.
[0048] In the present invention, by starting the motor 16, the rotating shaft 3 is driven to rotate, and then the multiple fixed rods 4 are driven to rotate, and then the multiple glass hemispheres 5 are driven to rotate. During the rotation of the glass hemisphere 5, friction is generated with the silk adsorption layer 46. Since the electron confinement capacity of glass is smaller than that of silk, during the friction process, the glass hemisphere 5 loses electrons, while the silk adsorption layer 46 gains electrons, and then the silk adsorption layer 46 generates static electricity. In addition, during the rotation of the glass hemisphere 5, it will intermittently abut against the semicircular head 11, pushing the semicircular head 11 to move, and in conjunction with the first spring 12, the cross bar 10 will move back and forth, thereby driving the sliding plug 7 to slide back and forth in a sealed manner. Under the action of the sliding plug 7, the alumina powder in the external silo will be drawn into the extraction chamber 701 through the one-way extraction pipe 8, and then the alumina powder in the extraction chamber 701 will enter the receiving barrel 2 through the one-way feeding pipe 9. After the alumina powder enters the receiving barrel 2, it will adhere to the silk adsorption layer 46 under the action of static electricity, thereby preventing the alumina powder from scattering everywhere and causing environmental pollution and waste.
[0049] Furthermore, during the extraction process, the reciprocating sealed sliding of the slide plug 7 can draw external hot air into the pump air chamber 702 through the one-way exhaust pipe 13, and then the hot air will enter the receiving barrel 2 through the one-way pump air pipe 14, which can heat the alumina powder to make it drier. After the temperature in the receiving barrel 2 increases, it is easier for the silk adsorption layer 46 to generate static electricity, thereby improving the adsorption capacity of alumina powder.
[0050] In addition, after the alumina powder enters the collecting barrel 2, the filter plate 15 will filter it. If the alumina powder is clumped, it will not be able to pass through the filter plate 15, but will stay on the upper end of the filter plate 15. The rotation of the rotating shaft 3 will drive the multiple first breaking rods 40 to rotate, and the rotating shaft 3 will also synchronously drive the first bevel gear 42 to rotate, and then drive the third bevel gear 45 to rotate, thereby driving the second bevel gear 43 to rotate, and driving the third shaft sleeve 48 to rotate. The third shaft sleeve 48 rotates in the opposite direction to the rotating shaft 3, and then drives the multiple second breaking rods 41 to rotate in the opposite direction. The first breaking rod 40 cooperates with the second breaking rod 41 to break up the alumina powder clumps on the filter plate 15 to facilitate its loading.
[0051] As more and more alumina powder is adsorbed in the receiving barrel 2, the weight of the receiving barrel 2 will become heavier, and then under the action of gravity, the mounting rod 35 will overcome the elastic force of the fourth spring 36 and slowly slide downward in the vertical slot 34. When the mounting rod 35 contacts the delay switch 37, the delay switch 37 will open (the delay switch 37 can remain closed for a period of time after opening and then automatically disconnect). At this time, the first electromagnet 22 is energized to generate magnetism, and then generate magnetic repulsion, pushing the first magnetic rod 20 into the first slot 21. At this time, the rotation of the rotating shaft 3 will drive the first shaft sleeve 17 to rotate, and then drive the multiple fan blades 18 to rotate, thereby blowing the material. The alumina powder adsorbed on the surface of the silk adsorption layer 46 will be blown off and then discharged through the discharge pipe 25, thereby loading the material. The delay switch 37 will disconnect after the delay, and the blowing will stop. This reciprocating process can be used for intermittent loading.
[0052] During feeding, the second electromagnet 31 will also be energized to generate magnetism, generating magnetic repulsion, thereby pushing the second magnetic rod 29 to move into the second slot 30. At this time, the rotating shaft 3 will synchronously drive the second sleeve 27 to rotate, and then drive multiple stirring rods 38 to rotate, thereby hitting the alumina powder. Since the alumina powder may clump together under the action of static electricity, it can be dispersed by the beating of the stirring rod 38, thereby preventing the alumina powder from clumping together and blocking the discharge pipe 25, affecting feeding.
[0053] When the stirring rod 38 rotates, it collides with the multiple rubber rods 39, causing the rubber rods 39 to vibrate. The vibration is transmitted to the receiving barrel 2, which can further vibrate the alumina powder, making it easier to fall off from the silk adsorption layer 46.
[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
