When the spiral conveying rod rotates, the blade pushes the protrusion, causing the outer cylinder to move toward the direction close to the upper cylinder body, and the protrusion moves toward the outside of the inner cylinder. When the side of the protrusion close to the axis of the inner cylinder collides with the blade, the outer cylinder moves away from the upper cylinder body, and the outer cylinder moves left and right to hit the hopper, causing the hopper and the inner cylinder to vibrate. When the side of the protrusion close to the axis of the inner cylinder separates from the blade, the protrusion moves into the inner cylinder to cut and crush the material in the inner cylinder.

[0007] Furthermore, a quantitative unloading mechanism is provided in the barrel body, and the quantitative unloading mechanism includes a receiving plate, an electronic scale and a baffle; a lower cylinder coaxial with the upper cylinder is fixedly installed in the barrel body, and there is a gap between the lower end of the upper cylinder and the upper end of the lower cylinder; the receiving plate is arranged in the lower cylinder for up and down movement, an electric push rod is fixed in the lower cylinder, a fixing seat is fixed on the upper end of the electric push rod, the electronic scale is arranged on the fixing seat, the receiving plate is arranged on the electronic scale, and the baffle is elastically slidably connected to the lower end of the upper cylinder.

[0008] Furthermore, the fixing seat is in sealing sliding contact with the inner wall of the lower cylinder, and the lower cylinder below the fixing seat is in communication with the barrel body.

[0009] Furthermore, a piston plate is elastically and sealingly slidably arranged up and down on the upper part of the upper cylinder.

[0010] Furthermore, a third inclined surface is provided at the upper end of the material receiving plate for allowing the material to slide down.

[0011] Furthermore, a second slide groove is provided at the lower end of the upper cylinder, an electromagnet is fixed on the top wall of the second slide groove, an iron plate slidably arranged in the second slide groove is connected to the upper end of the baffle, and a fourth spring is fixedly connected between the electromagnet and the iron plate; The receiving plate is provided with a second contact, the inner wall of the lower cylinder is provided with a first contact, and the second contact and the first contact are both connected to the control circuit of the electromagnet.

[0012] Furthermore, the upper end surface of the lower cylinder is provided with a second inclined surface, the outer side of the second inclined surface is inclined downward, and the lower end of the upper cylinder is provided with a fourth inclined surface adapted to the second inclined surface.

[0013] Furthermore, the cross section of the blade is inclined toward the upper cylinder at one end close to the spiral conveying rod.

[0015] Furthermore, one end of the outer cylinder close to the upper cylinder is inclined upward.

[0016] Compared with the prior art, the present invention has the following beneficial effects: when the feeding mechanism is conveying materials, the outer cylinder and the inner cylinder reciprocate left and right and hit the hopper, causing the inner cylinder and the hopper to vibrate. The vibration of the hopper allows the materials in the hopper to fall smoothly and has the effect of shaking the materials in the hopper apart. The vibration of the inner cylinder has the effect of shaking the materials in the inner cylinder apart.

[0017] The protrusion moves back and forth along the second opening, and when the protrusion moves into the inner cylinder, the protrusion cuts and crushes the material in the inner cylinder. At the same time, the protrusion drives the inner cylinder to vibrate, thereby shaking the material in the inner cylinder apart.

[0018] After the material enters the upper cylinder and falls onto the receiving plate, the electronic scale weighs the material. When the set weight is reached, the receiving plate moves up, and negative pressure is generated in the barrel. When the material on the receiving plate slides into the barrel, the negative pressure in the barrel generates suction force on the material on the receiving plate, and at the same time, the piston plate moves down to blow out the material on the receiving plate, so that the material on the receiving plate quickly and smoothly enters the barrel, completing quantitative feeding.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0022] like Figure 1-Figure 8 A graphene lead-acid battery conductive slurry preparation device is shown.

[0023] Example 1: Figure 1-Figure 8 As shown, the technical solution adopted by the present invention is as follows: a graphene lead-acid battery conductive slurry preparation device includes a barrel 1 and a feeding mechanism.

[0024] The barrel body 1 is provided with a liquid inlet 2, and a first control valve 3 is provided in the liquid inlet 2, and liquid material is added into the barrel body 1 through the liquid inlet 2. A stirring rod 12 is rotatably provided in the barrel body 1, and a first motor 4 is installed at the upper end of the barrel body 1, and the first motor 4 is drivingly connected to the stirring rod 12. A discharge port 14 is provided at the lower end of the barrel body 1, and a second control valve 15 is provided in the discharge port 14.

[0025] The barrel body 1 is fixedly connected with an upper barrel body 5 and a hopper 8. The upper barrel body 5 is communicated with the inside of the barrel body 1. A feeding structure is arranged between the upper barrel body 5 and the hopper 8. When the material is put into the hopper 8, the feeding mechanism transports the material from the hopper 8 to the upper barrel body 5.

[0026] The feeding mechanism includes an outer cylinder 7, a protrusion 23 and a screw conveying rod 19. The outer cylinder 7 is elastically slidably connected between the upper cylinder 5 and the hopper 8, and the end of the outer cylinder 7 close to the upper cylinder 5 is tilted upward. Specifically, a first opening is provided on one side of the hopper 8, and one end of the outer cylinder 7 extends into the hopper 8 through the first opening. A third opening is provided on one side of the upper cylinder 5, and the end of the outer cylinder 7 away from the hopper 8 extends into the upper cylinder 5 through the third opening.

[0027] A first chute 22 is provided on the outer circumference of the outer cylinder 7, and a limit block is slidably arranged in the first chute 22, and the limit block is fixedly connected to the hopper 8. A spring groove is provided on one end wall of the first chute 22, and a second spring 21 is fixedly connected between the limit block and the end wall of the spring groove away from the first chute 22. An arc block adapted to the outer cylinder 7 is fixedly connected to the hopper 8, and the arc block is located in the hopper 8. The arc block is used to block the first chute 22 to prevent the material in the hopper 8 from falling into the first chute 22. Figure 3 As shown, when the outer cylinder 7 slides left and right, the outer cylinder 7 hits the limit block through the end wall of the first slide groove 22, and then the hopper 8 vibrates, which is conducive to making the material in the hopper 8 fall and also conducive to shaking the material in the hopper 8 apart.

[0028] The inner cylinder 20 is coaxially fixedly installed in the outer cylinder 7. Both ends of the inner cylinder 20 are fixedly connected with flanges, and the inner cylinder 20 is fixedly connected to the outer cylinder 7 through the flanges, so that there is a gap between the inner wall of the outer cylinder 7 and the inner cylinder 20. A plurality of second openings are provided on the side wall of the inner cylinder 20, and a protrusion 23 is elastically slidably provided in each second opening, and a third spring 24 is fixedly connected between the protrusion 23 and the outer wall of the inner cylinder 20. Under the action of the third spring 24, one end of the protrusion 23 passes through the second opening and extends into the inner cylinder 20. A first inclined surface is provided on the side of the protrusion 23 close to the hopper 8.

[0029] The plurality of protrusions 23 are distributed at intervals along the spiral line 37 , and the length of the protrusions 23 is smaller than the pitch of the spiral line 37 . The spiral line 37 is coaxial with the inner cylinder 20 .

[0030] The screw conveying rod 19 is coaxially rotatably arranged in the inner cylinder 20. The second motor 9 is fixedly mounted on the hopper 8. One end of the screw conveying rod 19 extends outside the inner cylinder 20 and is coaxially fixedly connected to the second motor 9. A blade 25 is fixedly mounted on the screw conveying rod 19. The pitch of the blade 25 is equal to the pitch of the helix 37. Figure 8 As shown, the side of the blade 25 close to the screw conveying rod 19 is inclined toward the direction close to the upper cylinder 5. That is, there is an angle a between the cross section of the blade 25 and the axis of the screw conveying rod 19. In this way, when the side of the protrusion 23 close to the screw conveying rod 19 is separated from the blade 25, the protrusion 23 can move smoothly into the inner cylinder 20, avoiding interference of the blade 25 on the protrusion 23.

[0031] Working principle: Initially, if Figure 3 As shown, under the action of the second spring 21, the limit block abuts against the left end of the first slide groove 22. Under the action of the third spring 24, one end of the protrusion 23 extends into the moving inner cylinder 20.

[0032] During preparation, liquid material is introduced into the barrel 1 through the liquid inlet 2. The first motor 4 is started, and the first motor 4 stirs and mixes the material in the barrel 1. After the solid material is added into the hopper 8, the feeding mechanism conveys the solid material in the hopper 8 into the upper barrel 5. Some solid materials need to be added during the preparation process, because pouring all the solid materials into the barrel 1 at one time is likely to cause material agglomeration and uneven mixing, affecting the preparation effect.

[0033] When the feeding mechanism is working, the second motor 9 is started, and the second motor 9 drives the spiral conveying rod 19 to rotate, and the blade 25 rotates, so that the left side of the blade 25 is against the first inclined surface of the protrusion 23. As the blade 25 rotates, the blade 25 pushes the protrusion 23 to move left, and then the inner cylinder 20 and the outer cylinder 7 move left, and the limit block slides in the first slide groove 22 until the limit block hits the outer cylinder 7 and abuts against the right end of the first slide groove 22.

[0034] As the blade 25 rotates, under the action of the first inclined surface, the projection 23 overcomes the elastic force of the third spring 24 and moves away from the screw conveying rod 19 until the side of the projection 23 close to the screw conveying rod 19 abuts against the side of the blade 25 away from the screw conveying rod 19. At this time, because the blade 25 no longer limits the right side of the projection 23, the outer cylinder 7 moves quickly to the right under the action of the second spring 21 until the outer cylinder 7 hits the hopper 8.

[0035] As the blade 25 rotates, when the protrusion 23 is separated from the blade 25 on the side close to the spiral conveying rod 19 , the protrusion 23 quickly moves into the inner cylinder 20 under the action of the third spring 24 , and the protrusion 23 cuts and crushes the material in the inner cylinder 20 .

[0036] Therefore, as the blades 25 rotate, the outer cylinder 7 and the inner cylinder 20 move back and forth, so that the outer cylinder 7 continuously hits the hopper 8, causing the hopper 8 to vibrate, which is conducive to shaking out the materials in the hopper 8 and making the materials in the hopper 8 fall smoothly. At the same time, the left and right movement of the inner cylinder 20 and the impact of the hopper 8 also cause the inner cylinder 20 to vibrate, which is conducive to shaking out the materials in the inner cylinder 20. The protrusion 23 slides back and forth along the second opening. When the protrusion 23 moves quickly into the inner cylinder 20, the protrusion 23 cuts and crushes the materials in the inner cylinder 20. At the same time, when the protrusion 23 slides along the second opening, it also causes the inner cylinder 20 to vibrate, which is conducive to shaking out the materials in the inner cylinder 20.

[0037] Embodiment 2: This embodiment is a further improvement on the basis of embodiment 1.

[0038] A quantitative material discharging mechanism is arranged in the barrel body 1. The quantitative material discharging mechanism comprises a material receiving plate 35, an electronic scale 34 and a baffle 30.

[0039] like Figure 3 , Figure 5 , Figure 6 As shown, a lower cylinder 10 with openings at both ends is fixedly installed in the barrel body 1 through a connecting block 36, the lower end of the upper cylinder 5 is open, the upper cylinder 5 is coaxially arranged with the lower cylinder 10, and the lower end of the upper cylinder 5 is opposite to the upper end of the lower cylinder 10. And there is a gap between the upper cylinder 5 and the lower cylinder 10. A second slide groove 27 is vertically opened at the lower end of the upper cylinder 5. An electromagnet 26 is fixed on the top wall of the second slide groove 27, and an iron plate 29 is slidably connected in the second slide groove 27, and the iron plate 29 is fixedly connected to the baffle 30. A fourth spring 28 is fixedly connected between the iron plate 29 and the electromagnet 26. When the electromagnet 26 is disconnected, under the action of the fourth spring 28, the baffle 30 blocks the gap between the upper cylinder 5 and the lower cylinder 10.

[0040] The upper end of the lower cylinder 10 is provided with a second inclined surface, and the outer side of the second inclined surface is inclined downward. The lower end of the baffle 30 is provided with a fourth inclined surface adapted to the second inclined surface. When the baffle 30 contacts the lower cylinder 10, the second inclined surface and the fourth inclined surface match.

[0041] The receiving plate 35 is arranged in the lower cylinder 10 for vertical movement. A support plate 17 is fixed to the bottom end of the barrel 1, and an electric push rod 18 is fixedly installed on the support plate 17. The telescopic end of the electric push rod 18 is vertically upward, and a fixed seat 33 is fixedly installed on the telescopic end of the electric push rod 18. The fixed seat 33 is in sealing and sliding contact with the inner wall of the lower cylinder 10. An electronic scale 34 is installed on the fixed seat 33, and the receiving plate 35 is installed on the electronic scale 34.

[0042] The receiving plate 35 is provided with a second contact 32, and the upper inner wall of the lower cylinder 10 is provided with a first contact 31. The first contact 31 and the second contact 32 are both connected to the control circuit of the electromagnet 26. When the first contact 31 and the second contact 32 are in contact, the electromagnet 26 is energized.

[0043] A piston plate 6 is provided in a sealing and sliding manner up and down in the upper part of the upper cylinder 5. Specifically, a mounting plate is fixedly installed on the inner wall of the upper cylinder 5, and a first spring 16 is fixedly connected between the piston plate 6 and the mounting plate.

[0044] The upper end surface of the receiving plate 35 is provided with a third inclined surface, and the third inclined surface is inclined upward near the middle of the receiving plate 35 , that is, the middle of the receiving plate 35 bulges upward.

[0045] Working principle: Initially, the electromagnet 26 is powered off, and the first control valve 3 blocks the gap between the upper cylinder 5 and the lower cylinder 10. The second contact 32 is located below the first contact 31.

[0046] As the blade 25 rotates, the material in the hopper 8 is gradually transported into the upper cylinder 5, and the material entering the upper cylinder 5 falls onto the receiving plate 35, and the electronic scale 34 weighs the material on the receiving plate 35. When the material on the receiving plate 35 reaches the set weight, the second motor 9 is turned off first. The electric push rod 18 is started to move the receiving plate 35 upward, and the second contact 32 gradually moves upward. When the second contact 32 contacts the first contact 31, the electromagnet 26 is energized. Under the attraction of the electromagnet 26, the iron plate 29 moves upward, and the baffle 30 moves into the second chute 27. When the first contact 31 contacts the second contact 32, the electric push rod 18 is stopped. At this time, the receiving plate 35 corresponds to the interval between the upper cylinder 5 and the lower cylinder 10, and the upper end surface of the receiving plate 35 is above the top of the lower cylinder 10, and the material on the receiving plate 35 slides into the barrel 1.

[0047] During the upward movement of the receiving plate 35, the space in the lower cylinder 10 below the fixed seat 33 gradually increases, causing negative pressure in the barrel body 1. At the same time, the space in the lower cylinder 10 above the fixed seat 33 gradually decreases, causing the piston plate 6 to overcome the elastic force of the first spring 16 and move upward.

[0048] When the baffle 30 moves upward, the negative pressure in the barrel body 1 sucks the material on the receiving plate 35 into the barrel body 1. At the same time, the piston plate 6 moves downward under the action of the first spring 16, and the air in the upper cylinder 5 flows out through the gap between the upper cylinder 5 and the lower cylinder 10, which is conducive to blowing the material on the receiving plate 35 into the barrel body 1. This is conducive to making the material on the receiving plate 35 enter the barrel body 1 quickly and smoothly.

[0049] Afterwards, the electric push rod 18 is started to move the receiving plate 35 downward, the first contact 31 and the second contact 32 are separated, the electromagnet 26 is powered off, and the baffle 30 moves downward to block the gap between the upper cylinder 5 and the lower cylinder 10.

[0050] Embodiment 3: This embodiment is an improvement based on the embodiment barrel 1.

[0051] A temperature measuring module 13 is provided on the stirring rod 12. A heating plate 11 is provided on the inner wall of the barrel body 1. The material in the barrel body 1 is heated by the heating plate 11.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
