[0043] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0044] According to some embodiments of this utility model, refer to Figures 1 to 7 The sodium electrode anode powder forming equipment includes a housing 100, a forming plate 110, a feeding assembly 200, a pressing assembly 300, a lifting assembly 400, and a sweeping assembly 500. The forming plate 110 is located inside the housing 100, is horizontally positioned, and has multiple forming holes 111. Figure 3 In this embodiment, the forming holes 111 are arranged in an 11×12 array. The forming holes 111 extend through the upper and lower sides of the forming plate 110 in the vertical direction. The feeding assembly 200 is used to transport powder to the upper surface of the forming plate 110. The pressing assembly 300 is disposed inside the housing 100. The pressing assembly 300 includes a first driving component 310 and a pressure plate 320. The pressure plate 320 is located above the forming plate 110. The lower end surface of the pressure plate 320 is provided with a plurality of pressing blocks 321. The first driving component 310 can drive the pressure plate 320 to move in the vertical direction so that the pressing blocks 321 enter or leave the forming holes 111. The lifting assembly 400 is located inside the housing 100. The lifting assembly 400 includes a second driving component 410 and a lifting plate 420. The lifting plate 420 is located below the forming plate 110. Multiple lifting blocks 421 are provided on the upper surface of the lifting plate 420. The second driving component 410 can drive the lifting blocks 421 to move vertically, causing them to enter or exit the forming holes 111. The multiple forming holes 111, multiple pressing blocks 321, and multiple lifting blocks 421 correspond one-to-one. The lifting height of the lifting blocks 421 can be continuously varied and can be locked and stopped at any height. The pushing and sweeping assembly 500 is used to push and sweep powder located on the upper surface of the forming plate 110 into the forming holes 111, or to push and sweep compacted material 120 located on the upper surface of the forming plate 110 out of the forming plate 110.
[0045] In this embodiment, the forming hole 111 is a round hole, and the pressing block 321 and the lifting block 421 are cylindrical; the forming hole 111 can be changed to a square hole as required, while the pressing block 321 and the lifting block 421 are square columns, etc.
[0046] Understandably, referring to Figure 4 The second driving component 410 drives the lifting plate 420 to move upward, causing the lifting block 421 to insert upward into the forming hole 111, as shown in the figure. Figure 2 and Figure 3The feeding component 200 transports the powder to the left side of the upper surface of the forming plate 110. At this time, the powder accumulates on the upper surface of the forming plate 110 and is located to the right of the pushing component 500. The pushing component 500 moves from left to right and pushes the powder on the upper surface of the forming plate 110 to the right, so that the powder is pushed into multiple forming holes 111, and all forming holes 111 are filled with powder. Since the upper end of the lifting block 421 is located in the forming hole 111, the lifting block 421 supports the powder and prevents the powder from falling out of the forming hole 111. The pushing component 500 then moves back to the initial position from right to left. Next, refer to Figure 4 and Figure 5 The first driving component 310 drives the pressure plate 320 to move downward, causing the pressure block 321 to insert downward into the forming hole 111. During the downward movement of the pressure block 321, the pressure block 321 and the lifting block 421 gradually approach each other, thereby compressing the powder. The powder located in the forming hole 111 is compacted into compacted material 120. (Refer to...) Figure 5 and Figure 6 The first driving component 310 then drives the pressure plate 320 to move upward and disengage from the forming hole 111. The second driving component 410 then drives the lifting plate 420 to move upward. The lifting block 421 pushes out the compacted material 120 upward, causing the compacted material 120 to disengage from the forming hole 111 and move to the upper end face of the forming plate 110. The pushing and sweeping component 500 then moves from left to right to push the compacted material 120 located on the upper end face of the forming plate 110 to the right and out of the forming plate 110.
[0047] To improve the molding quality and demolding efficiency of the compacted material 120 and prevent powder leakage during the compaction process, this embodiment optimizes the fit between the molding hole 111, the pressing block 321, and the lifting block 421. Specifically, the inner wall of the molding hole 111 is polished to reduce the frictional resistance when the pressing block 321 and the lifting block 421 move up and down, and to help the compacted material 120 be smoothly ejected after compaction, avoiding sticking or breakage.
[0048] More preferably, a precise fit clearance is maintained between the outer wall of the pressing block 321 and the inner wall of the forming hole 111, as well as between the outer wall of the lifting block 421 and the inner wall of the forming hole 111. This ensures that the pressing block 321 and the lifting block 421 are accurately guided and run smoothly without jamming during reciprocating motion, and also effectively blocks and seals the powder, preventing it from falling down through the gap between the lifting block 421 and the wall of the forming hole 111. This ensures the accuracy of powder metering in each forming hole 111, and improves the density uniformity and material utilization rate of the final product.
[0049] This sodium-ion battery anode powder forming equipment can fill multiple forming holes 111 with powder, thereby producing multiple compacted materials 120 at one time. It can automatically and continuously produce materials. From material distribution to finished product collection, it can be fully automated through a set program, ensuring continuous production, meeting the needs of large-scale production, and improving production efficiency.
[0050] Furthermore, refer to Figure 2 The housing 100 is equipped with a collection hopper 600, which is located on the right side of the molding plate 110. The push-sweep assembly 500 can push the compacted material 120 located on the upper surface of the molding plate 110 to the right into the collection hopper 600.
[0051] Furthermore, refer to Figure 2 The sodium-ion battery anode powder forming equipment also includes a nitrogen pipe 630, the outlet of which is inserted into the housing 100. Before the sodium-ion battery anode powder forming equipment starts producing compacted material 120, the nitrogen pipe 630 supplies nitrogen into the housing 100. Oxygen in the housing 100 is discharged through the outlet of the collecting hopper 600, increasing the nitrogen content in the housing 100, thereby reducing the risk of dust explosion and improving the safety of the production process.
[0052] Preferred, refer to Figure 2 The discharge end of the collecting hopper 600 is located outside the housing 100. The discharge end of the collecting hopper 600 is equipped with a rotary valve 610. When it is necessary to discharge gas, or to discharge powder and compacted material 120 from the collecting hopper 600, the rotary valve 610 is opened, allowing the powder and compacted material 120 to be discharged. Before producing compacted material 120, the rotary valve 610 is opened, and nitrogen gas is supplied to the housing 100 through the nitrogen pipe 630 to displace oxygen. The oxygen then leaves the housing 100 through the rotary valve 610. During the production of compacted material 120, the rotary valve 610 is closed, allowing the compacted material 120 to be temporarily stored in the collecting hopper 600.
[0053] Preferred, refer to Figure 2The sodium electrode anode powder forming equipment also includes a screen 620, which is located below the discharge end of the collecting hopper 600. The screen 620 is used to screen the powder and compacted material 120. It is understood that when the pushing device pushes the powder into the forming hole 111, some powder remains on the upper surface of the forming plate 110. During the process of the pushing device pushing the compacted material 120 to the right into the collecting hopper 600, the powder is also pushed into the collecting hopper 600. When the mixture of compacted material 120 and powder leaves the collecting hopper 600 and is screened on the screen 620, the powder passes through the screen 620 into the collecting bin 640 and is subsequently recycled to the storage tank 210 of the feeding assembly 200 for reuse, reducing powder loss. The compacted material 120 remaining on the screen 620 is collected and moved to another designated location.
[0054] Furthermore, refer to Figure 2 The feeding assembly 200 includes a storage bin 210 and a screw feeder 220. The feed end of the screw feeder 220 is connected to the storage bin 210. The screw feeder 220 passes through the housing 100 and its discharge end is inserted into the housing 100. The discharge end of the screw feeder 220 faces the left side of the forming plate 110. Preferably, the screw feeder 220 includes a barrel, a feeding screw, and a third drive component. The feeding screw is located inside the barrel. The feed end of the barrel is connected to the storage bin 210, and the discharge end of the barrel is inserted into the housing 100 and faces the forming plate 110. The third drive component drives the feeding screw to rotate around its own axis. The barrel is inclined downward from left to right, with the right end of the barrel being the discharge end, and the right end of the barrel facing downward toward the forming plate 110. The feeding screw and the barrel are coaxially arranged. When the feeding screw rotates, it can push the powder from left to right and downward onto the forming plate 110. The spiral feeding component 220 can control the single discharge amount by controlling the start time of the third drive component, thus preventing too much or too little powder from falling into the forming plate 110. Preferably, the discharge end of the material cylinder is equipped with an electromagnetic valve, which is opened during the feeding process and closed when feeding stops, preventing the powder in the material cylinder from automatically detaching from the cylinder under gravity. Preferably, an appropriate amount of water can be added to the storage tank 210 as a binder, the amount added ensuring that the mixture can be formed under pressure and has fluidity in the mixed state. The third drive component is a servo motor.
[0055] Preferably, the top of the housing 100 is a sealing cover, and the first driving component 310 passes through the sealing cover. The first driving component 310 and the sealing cover are flexibly connected by a hose. When the first driving component 310 moves in the up and down direction, the hose expands and contracts to ensure stable sealing between the sealing cover and the first driving component 310 and prevent leakage.
[0056] Furthermore, refer to Figure 2 and Figure 3The pusher assembly 500 includes a pusher plate 520 and a fourth drive component 510. The pusher plate 520 extends in the front-rear direction. The front end of the pusher plate 520 is located in front of the front side of the forming plate 110, and the rear end of the pusher plate 520 is located behind the rear side of the forming plate 110. The fourth drive component 510 is used to drive the pusher plate 520 to move in the left-right direction. The lower side of the pusher plate 520 can fit against the upper end surface of the forming plate 110, thereby ensuring that the pusher plate 520 can push the powder. When the powder passes through the forming hole 111, it will fall into the forming hole 111. When the forming hole 111 on the left is full, the remaining powder will continue to move to the right and enter the next forming hole 111.
[0057] Furthermore, refer to Figures 4 to 6 The diameter of the pressing block 321 is smaller than the diameter of the forming hole 111, ensuring that the pressing block 321 can be inserted into the forming hole 111. The diameter of the lifting block 421 is smaller than the diameter of the forming hole 111, ensuring that the lifting block 421 can be inserted into the forming hole 111. The height of the lifting block 421 is greater than the thickness of the forming plate 110 in the vertical direction, ensuring that the lifting block 421 can lift the compacted material 120 located in the forming hole 111 upwards out of the forming hole 111.
[0058] Furthermore, the forming plate 110 is detachably connected to the housing 100 by bolts, the pressure plate 320 is detachably connected to the first drive component 310 by bolts, and the lifting plate 420 is detachably connected to the second drive component 410 by bolts. The forming plate 110, pressure plate 320, and lifting block 421 are replaceable, thereby simultaneously changing the shape and number of the forming hole 111, pressure block 321, and lifting block 421 to accommodate the production needs of compacted materials 120 in multiple shapes.
[0059] In this embodiment, the first driving component 310, the second driving component 410, and the fourth driving component 510 are hydraulic push rods, cylinders, or electric push rods.
[0060] The workflow of this embodiment includes:
[0061] Open the rotary valve 610, and the nitrogen pipe 630 supplies nitrogen to the chamber 100 to replace the oxygen, so that the oxygen concentration in the chamber is less than 5%. Use corn starch as raw material and add 1.2% water as a binder, mix evenly to form powder, and add it to the storage tank 210. Oxygen leaves the chamber 100 through the rotary valve 610. Then close the rotary valve 610, and the second drive component 410 drives the lifting plate 420 to move upward, so that the lifting block 421 is inserted into the forming hole 111. The third drive component drives the feeding screw to rotate around its own axis. When the feeding screw rotates, it pushes the powder in the barrel from left to right and downward, so that the powder falls on the left side of the upper end face of the forming plate 110. Add 20kg of powder to the upper end face of the forming plate 110. At this time, the powder accumulates on the upper surface of the forming plate 110 and is located to the right of the pushing and sweeping assembly 500. The fourth driving component 510 drives the pusher plate 520 to move from left to right and pushes the powder on the upper surface of the forming plate 110 to the right, so that the powder is pushed into multiple forming holes 111. The depth of the forming holes 111 is 12mm. When the powder passes through the forming holes 111, it will fall into the forming holes 111. When the forming hole 111 on the left is full, the remaining powder will continue to move to the right and enter the next forming hole 111, so that multiple forming holes 111 are filled with powder. Since the upper end of the lifting block 421 is located in the forming hole 111, the lifting block 421 supports the powder and prevents the powder from falling out of the forming hole 111. The fourth driving component 510 then drives the pusher plate 520 to move from right to left back to the initial position. Next, the first driving component 310 drives the pressure plate 320 to move downward, causing the pressure block 321 to insert downward into the forming hole 111. During the downward movement of the pressure block 321, the pressure block 321 and the lifting block 421 gradually approach each other, thereby compressing the powder. The extrusion pressure is 10 MPa, and the time lasts for 10 seconds. At this time, the lifting block 421 remains stationary while the pressure block 321 extrudes downward, or the lifting block 421 extrudes upward while the pressure block 321 extrudes downward. The powder in the forming hole 111 is compacted into compacted material 120. The first driving component 310 then drives the pressure plate 320 to move upward and disengage from the forming hole 111. The second driving component 410 then drives the lifting plate 420 to move upward. The lifting block 421 pushes the compacted material 120 upward, causing the compacted material 120 to disengage from the forming hole 111 and move to the upper end face of the forming plate 110. The fourth driving component 510 then drives the push plate 520 to move from left to right, pushing the compacted material 120 located on the upper end face of the forming plate 110 to the right and sweeping it into the collection hopper 600. At this time, the upper end face of the lifting block 421 is flush with the upper end face of the forming plate 110, preventing the compacted material 120 from falling back into the forming hole 111. Then, the lifting block 421 lowers again to a certain height as a support for the powder in the forming hole 111.After repeated cycles, the collection hopper 600 contains multiple compacted materials 120. When the rotary valve 610 is opened, the mixture of compacted materials 120 and powder leaves the collection hopper 600 and falls onto the screen 620 for screening. The powder passes through the screen 620 and enters the collection bin 640, and is subsequently recycled to the storage bin 210 of the feeding assembly 200 for reuse, reducing powder loss. The compacted materials 120 remaining on the screen 620 are collected and moved to another designated location. The particles on the screen are those with a density of 1.04 g / cm3 and a thickness of 5 mm.
[0062] In another embodiment, potato starch is used as the raw material, with a water content of 0.8%. The depth of the forming hole 111 is adjusted to 15mm by the lifting block 421 and the pressing block 321; the discharge rate of the feeding screw is controlled at 23kg. The mutual extrusion pressure between the lifting block 421 and the pressing block 321 is 15MPa for 10s. Particles with a density of 1.12g / cm3 and a thickness of 5.8mm are obtained.
