[0001] This utility model relates to the field of feeding machine technology, and in particular to a feeding machine for the synthesis of nano copper powder. Background Technology
[0002] Nano copper powder is a purplish-brown or purplish-black powder used in the production of microelectronic devices, for manufacturing terminals of multilayer ceramic capacitors, and as a catalyst in the reaction process of carbon dioxide and hydrogen to synthesize methanol. It can also be used as a petroleum lubricant and in the pharmaceutical industry. Chalcocite is required as a raw material in the production of nano copper powder, so a feeder is needed to convey and feed chalcocite.
[0003] When feeding chalcocite, in order to obtain chalcocite powder that meets the particle size requirements, chalcocite needs to be screened. In the existing technology, the material is relatively concentrated on the screening box during the chalcocite screening process, resulting in low screening efficiency. Furthermore, if the material blocks the screening holes during the screening process, the screening efficiency of the device will decrease. Therefore, we propose a feeder for the synthesis of nano copper powder to solve the above-mentioned problems. Utility Model Content

[0006] To solve the above technical problems, this utility model provides a feeding machine for synthesizing nano copper powder, which adopts the following technical solution: it includes a feeding box, and a screening box is set inside the feeding box by a placement component. There is a gap between the outer side wall of the screening box and the inner side wall of the feeding box. The vertical center lines of the feeding box and the screening box are on the same vertical line. A vibration component is set on the feeding box. Several uniformly arranged screening holes are fixedly opened at the bottom of the screening box. An anti-clogging component is set inside the screening box.
[0007] The anti-clogging component includes an internal gear ring, which is rotatably mounted on the inner wall of the top of the screening box. A fixing plate is fixedly mounted on the top of the screening box, and a first motor is fixedly mounted on the top of the fixing plate. The drive end of the first motor movably passes through the bottom of the fixing plate, and a gear is fixedly connected to the lower end of the drive end of the first motor.

A brush is fixedly mounted on the lower surface of the stirring rod, and the brush is movably attached to the inner wall of the bottom of the screening box.
[0008] Preferably, the placement assembly includes two placement blocks, which are symmetrically distributed about the center line of the feeding box. The placement blocks are fixedly installed on the inner wall of the feeding box. Two mounting blocks symmetrically distributed about the center line of the screening box are fixedly installed on the outer wall of the screening box. A rod is fixedly installed at the bottom of the mounting block. A limiting hole is fixedly opened in the middle of the placement block. The rod and the limiting hole are adapted to each other. A spring is fixedly installed at the bottom of the mounting block. The spring is movably sleeved on the outer ring of the rod. The bottom of the spring and the placement block are movably fitted together.
[0009] Preferably, the vibration assembly includes an electric push rod fixedly mounted on the outer wall of the feeding box, a second motor fixedly mounted on the telescopic end of the electric push rod, a rotating shaft fixedly connected to the drive end of the second motor, and a cam fixedly mounted on the outer ring of the rotating shaft, the cam being located directly above the mounting block.
[0010] Preferably, a sleeve rod is fixedly provided on the outer wall of the feeding box, the electric push rod and the sleeve rod are symmetrically distributed about the center line of the feeding box, a movable rod is slidably provided inside the sleeve rod, a support block is fixedly provided on the top of the movable rod, the end of the rotating shaft away from the second motor is rotatably connected to the support block through a bearing, and two cams are provided, the two cams are symmetrically distributed about the center line of the cam.

[0015] 1. By installing the anti-clogging component, the first motor is started during the vibration of the screening box, driving the gear to rotate, which in turn drives the internal gear ring, connecting rod, stirring rod and brush to rotate synchronously. This allows the brush to stir the chalcocite powder inside the screening box, so that the chalcocite powder can be evenly spread inside the screening box, improving the screening efficiency. In addition, the brush cleans the screening holes, thus avoiding the problem of the screening holes being blocked by material. This solves the problem that in the existing nano copper powder synthesis feeder for chalcocite screening, the material is relatively concentrated on the screening box, resulting in low screening efficiency. Furthermore, if the material blocks the screening holes during the screening process, it will cause the screening efficiency of the device to decrease.
[0016] 2. When it is necessary to clean the chalcocite powder inside the screening box that does not meet the particle size requirements, start the electric push rod to drive the second motor and rotating shaft to move upward and reset. Then hook the two lifting rings to remove the screening box from the feed box. This makes it easy to pour out the chalcocite powder that does not meet the particle size requirements and crush it again, thus improving the practicality of the device. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 The present invention provides an embodiment of a feeding machine for synthesizing nano-copper powder, comprising a feeding box 1, a connecting pipe 2, a conveying pipe 3, and a reaction vessel 4. The connecting pipe 2 is fixedly installed at the bottom of the feeding box 1, and the conveying pipe 3 is connected between the connecting pipe 2 and the reaction vessel 4. Chalcocite powder raw material is poured into the feeding box 1, and then enters the reaction vessel 4 through the connecting pipe 2 and the conveying pipe 3 in sequence, and other reactants are added to synthesize and produce nano-copper powder.
[0026] When feeding chalcocite powder, in order to obtain chalcocite powder that meets the particle size requirements, chalcocite needs to be screened. Therefore, a screening box 5 is set inside the feeding box 1 by a placement component. There is a gap between the outer wall of the screening box 5 and the inner wall of the feeding box 1. Several uniformly arranged screening holes 6 are fixedly opened at the bottom of the screening box 5. The vertical center lines of the feeding box 1 and the screening box 5 are on the same vertical line. A vibration component is set on the feeding box 1. The screening box 5 is placed inside the feeding box 1 by the placement component, and then the vibration component drives the screening box 5 to vibrate, so that the chalcocite powder that meets the particle size requirements falls into the feeding box 1 through the screening holes 6, and then enters the reaction tank 4 through the connecting pipe 2 and the conveying pipe 3 in sequence.
[0027] Considering that the material is relatively concentrated on the screening box 5 during the screening process of chalcocite, resulting in low screening efficiency, and that the screening efficiency of the device will decrease if the material blocks the screening holes 6 during the screening process, this utility model provides an anti-blocking component inside the screening box 5. The anti-blocking component includes an internal gear ring 7, which is rotatably mounted on the inner wall of the top of the screening box 5. A fixing plate 8 is fixedly mounted on the top of the screening box 5, and a first motor 9 is fixedly mounted on the top of the fixing plate 8. The drive end of the first motor 9 moves through the bottom of the fixing plate 8, and a gear 10 is fixedly connected to the lower end of the drive end of the first motor 9. The gear 10 and the internal gear ring 7 mesh with each other. Two connecting rods 11 are fixedly mounted on the bottom of the internal gear ring 7. The two connecting rods 11 are symmetrically distributed about the center line of the internal gear ring 7. A stirring rod 12 is fixedly connected between the lower ends of the two connecting rods 11. A brush 13 is fixedly mounted on the lower surface of the stirring rod 12, and the brush 13 moves and fits against the inner wall of the bottom of the screening box 5.
[0028] Specifically, during the vibration of the screening box 5, the first motor 9 is started, driving the gear 10 to rotate, which in turn drives the internal gear ring 7, connecting rod 11, stirring rod 12, and brush 13 to rotate synchronously. This allows the brush 13 to stir the chalcocite powder inside the screening box 5, ensuring that the chalcocite powder is evenly distributed inside the screening box 5, thus improving screening efficiency. In addition, the brush 13 cleans the screening holes 6, preventing the screening holes 6 from being blocked by material. This solves the problem that in the existing nano-copper powder synthesis feeder for chalcocite screening, the material is concentrated on the screening box 5, resulting in low screening efficiency. Furthermore, if the material blocks the screening holes 6 during the screening process, it will cause a decrease in the screening efficiency of the device.
[0029] Furthermore, the placement assembly includes two placement blocks 14, which are symmetrically distributed about the center line of the feeding box 1. The placement blocks 14 are fixedly installed on the inner wall of the feeding box 1. Two mounting blocks 15 are fixedly installed on the outer wall of the screening box 5, which are symmetrically distributed about the center line of the screening box 5. A rod 16 is fixedly installed at the bottom of the mounting block 15. A limiting hole is fixedly opened in the middle of the placement block 14. The rod 16 is adapted to the limiting hole. A spring 17 is fixedly installed at the bottom of the mounting block 15. The spring 17 is movably sleeved on the outer ring of the rod 16. The two rods 16 are respectively inserted into the limiting hole, so that the bottom of the spring 17 and the placement block 14 move and fit together, thereby completing the placement of the screening box 5.
[0030] Furthermore, the vibration assembly includes an electric push rod 18 fixedly mounted on the outer wall of the feeding box 1. A second motor 19 is fixedly mounted on the telescopic end of the electric push rod 18. A rotating shaft 20 is fixedly connected to the drive end of the second motor 19. A cam 21 is fixedly mounted on the outer ring of the rotating shaft 20. The cam 21 is located directly above the mounting block 15. A sleeve rod 22 is fixedly mounted on the outer wall of the feeding box 1. The electric push rod 18 and the sleeve rod 22 are symmetrically distributed about the center line of the feeding box 1. A movable rod 23 is slidably mounted inside the sleeve rod 22. A support block 24 is fixedly mounted on the top of the movable rod 23. The end of the rotating shaft 20 away from the second motor 19 is rotatably connected to the support block 24 through a bearing. There are two cams 21, which are symmetrically distributed about the center line of the cam 21.
[0031] After the screening box 5 is placed, the electric push rod 18 is started, which drives the second motor 19, rotating shaft 20, cam 21, support block 24 and movable rod 23 to move downward synchronously, so that the two cams 21 are respectively in contact with the two mounting blocks 15. Then the electric push rod 18 is stopped, and the second motor 19 is started, which drives the rotating shaft 20 and cam 21 to rotate. With the cooperation of the spring 17, the mounting block 15 and screening box 5 are driven to move up and down repeatedly, which in turn drives the screening box 5 to vibrate, so that the chalcocite powder that meets the particle size requirements falls into the interior of the feeding box 1 through the screening hole 6.
[0032] When it is necessary to clean the chalcocite powder inside the screening box 5 that does not meet the particle size requirements, the electric push rod 18 is started in reverse, which drives the second motor 19 and the rotating shaft 20 to move upward and reset. Since there are two symmetrically arranged lifting rings 25 fixed on the top of the screening box 5, the screening box 5 can be taken out from the feed box 1 by hooking the two lifting rings 25, so that the chalcocite powder that does not meet the particle size requirements can be poured out and crushed again.
[0033] Furthermore, three support rods 26 evenly distributed in a ring are fixedly installed at the lower end of the feeding box 1.
[0034] Working principle: The chalcocite powder raw material is poured into the screening box 5. The electric push rod 18 is started, which drives the second motor 19, rotating shaft 20, cam 21, support block 24 and movable rod 23 to move downward synchronously. After the two cams 21 are respectively in contact with the two mounting blocks 15, the electric push rod 18 is stopped. The second motor 19 is started, which drives the rotating shaft 20 and cam 21 to rotate. With the cooperation of the spring 17, the mounting block 15 and screening box 5 are driven to move up and down repeatedly, which in turn drives the screening box 5 to vibrate. This allows the chalcocite powder that meets the particle size requirements to fall into the feed box 1 through the screening hole 6. Then, it enters the reaction tank 4 through the connecting pipe 2 and the conveying pipe 3 in sequence. Other reactants are added to synthesize and produce nano copper powder.
[0035] During the vibration of the screening box 5, the first motor 9 is started simultaneously, driving the gear 10 to rotate, which in turn drives the internal gear ring 7, connecting rod 11, stirring rod 12 and brush 13 to rotate synchronously. This allows the brush 13 to stir the chalcocite powder inside the screening box 5, so that the chalcocite powder can be evenly spread inside the screening box 5, improving screening efficiency. In addition, the brush 13 cleans the screening holes 6, thereby preventing the screening holes 6 from being blocked by material.
[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
