Description

Technical Field

[0001] This invention relates to the field of dough forming technology, specifically to a powder pressing and forming machine and method. Background Technology

[0002] In the food processing industry, powder pressing and forming is a key production process, widely used in the manufacture of various products such as dough cakes, feed cakes, and food additive cakes.

[0003] However, existing powder compact forming equipment still has the following problems:

[0004] 1. Most equipment uses a single feeding mode for its feeding mechanism. The replenishment of empty material trays requires frequent manual intervention, which cannot achieve continuous tray feeding, resulting in long production interruption time and limited overall production efficiency.

[0005] Second, powder is prone to clumping during storage and transportation. The equipment lacks an effective powder dispersing structure. When clumped powder directly enters the pressing process, it will cause problems such as uneven powder density and poor forming effect, which will affect product quality.

[0006] Third, spillage is prone to occur during the powder conveying process, which not only wastes raw materials but also requires additional manual labor for cleaning, increasing production and maintenance costs;

[0007] Fourth, the existing equipment's processes of pressing, receiving, unloading, and stacking are not smoothly connected, relying heavily on manual assistance for transfer, resulting in low automation integration and difficulty in meeting the needs of large-scale continuous production.

[0008] Based on this, the present invention designs a powder pressing and forming machine and method to solve the above problems. Summary of the Invention

[0023] The lower end of the main hopper is higher than the upper end of the baffle plate;

[0024] Furthermore, a first powder receiving tray for receiving residual powder in the powder separation chamber can be detachably installed on the upper left side of the frame;

[0025] Furthermore, the powder feeding mechanism includes a powder receiving and pushing component and an automatic stirring and carrying component; both the powder receiving and pushing component and the automatic stirring and carrying component are connected to the frame; and the powder receiving and pushing component is connected to the automatic stirring and carrying component.

[0026] Furthermore, the automatic stirring and bearing assembly includes a powder receiving tray and a powder stirring assembly; the front and rear sides of the powder receiving tray are slidably connected to the feeding guide rod; the output end of the first rigid chain pusher is fixedly connected to the middle of the left end of the powder receiving tray.

[0027] The powder mixing assembly is connected to the powder receiving tray;

[0028] Furthermore, the movable lower mold assembly includes a third cylinder slide assembly, a movable pad, a powder receiving tray sealing plate, a powder cake sealing plate, a second powder leakage receiving tray, and a Z-shaped receiving rod; the third cylinder slide assembly is fixedly installed in the middle left side of the frame; the movable pad is fixedly connected to the moving end of the third cylinder slide assembly; the powder receiving tray sealing plate and the powder cake sealing plate are sequentially fixedly installed on the upper left and right sides of the movable pad.

[0035] To better achieve the objectives of this invention, a method of use is also provided, comprising the following steps:

[0036] Step 1: The continuous empty material tray feeding mechanism first controls the empty material tray to move to the feeding station; the powder feeding mechanism moves to the right to the powder receiving station, and the movable lower mold assembly moves to the right along with the powder feeding mechanism;

[0037] Step 2: The continuous empty material tray feeding mechanism pushes the empty material tray at the feeding station to the left onto the movable lower mold assembly; and while the movable lower mold assembly moves to the right, it controls the follow-up powder blocking mechanism to move to the left, blocking the right side of the pressing mechanism.

[0038] Step 3: The powder storage mechanism moves the powder, causing it to fall into the powder feeding mechanism. During the powder receiving process, the powder feeding mechanism also breaks up any clumps of powder inside. After the powder feeding mechanism has completed the set amount of powder receiving, the powder storage mechanism stops working. Then, the powder feeding mechanism continues to move to the right and separates from the left side of the movable lower mold assembly, and comes into contact with the pressing mechanism. The powder in the powder feeding mechanism then falls into the pressing mechanism, and the movable lower mold assembly also collects the powder that spills during the movement of the powder feeding mechanism.

[0039] Step 4: The powder feeding mechanism resets to the left; the pressing mechanism then presses the powder to form the powder cake.

[0040] Step 5: After the powder compact is pressed into shape, the movable lower mold assembly will drive the empty material tray to move to the left until the empty material tray moves to the lower side of the pressing mechanism; the follow-up powder blocking mechanism will also reset to the right to release the blockage on the right side of the pressing mechanism.

[0041] Step 6: The receiving mechanism pushes the empty material tray upward until the empty material tray completely covers the lower side of the pressing mechanism, and the pressing mechanism pushes the powder cake into the empty material tray;

[0042] Step 7: The cake receiving mechanism moves the full-load tray filled with powder cakes back to the movable lower mold assembly; the movable lower mold assembly moves the full-load tray to the right to the position of the finished product tray unloading and stacking mechanism; then the finished product tray unloading and stacking mechanism lifts the full-load tray, separating it from the movable lower mold assembly, and then the movable lower mold assembly resets to the left; the finished product tray unloading and stacking mechanism moves the full-load tray down and to the right to perform the stacking operation.

[0043] Compared with existing technologies, the advantages of this invention are as follows: Through the coordinated operation of a continuous empty material tray feeding mechanism, a multi-station powder transfer mechanism, a separate powder cake pressing mechanism, and a finished product tray unloading and stacking mechanism, a fully automated production process is constructed, from empty material tray replenishment, powder conveying, cake pressing to finished product stacking. This reduces production downtime, improves overall production efficiency, and can meet the needs of large-scale continuous production. The powder storage mechanism achieves quantitative powder conveying through a powder separation chamber composed of a belt conveyor and baffles, avoiding uneven feeding. The powder feeding mechanism effectively breaks up clumps formed during storage and conveying, ensuring uniform powder distribution. Simultaneously, the follow-up powder blocking mechanism can block the right side of the cake pressing mechanism during powder conveying, preventing powder from spilling into the empty material tray. The powder leakage channel of the movable lower mold assembly, in conjunction with the powder leakage receiving plate, can collect the powder spilled during conveying, reducing powder waste and ensuring a clean pressing environment.

[0060] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0061] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0062] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-13 A powder cake forming machine includes a frame 1, and also includes a continuous empty material tray feeding mechanism, a multi-station powder transfer mechanism, a separate powder cake pressing mechanism and a finished product tray unloading and stacking mechanism.

[0063] The continuous empty material tray feeding mechanism, used to control the movement of the empty material tray to achieve continuous tray feeding operation, is located on the front right side of the frame 1 and is connected to the frame 1.

[0064] A multi-station powder transfer mechanism for supplying powder for the pressing of powder cakes is installed on the left side of the frame 1;

[0065] The multi-station powder transfer mechanism includes a powder storage mechanism 4 and a powder feeding mechanism 5; both the powder storage mechanism 4 and the powder feeding mechanism 5 are installed on the left side of the frame 1.

[0066] A separate powder pressing mechanism for pressing powder cakes is mounted on frame 1.

[0067] The separate powder cake pressing mechanism includes a movable lower mold assembly 6 for receiving empty material trays and assisting in the pressing operation, a pressing mechanism 7 for pressing powder to achieve powder cake forming operation, a follow-up powder blocking mechanism 8 for preventing powder from falling into the empty material tray, and a receiving mechanism 12 for controlling the upward movement of the empty material tray to receive powder cakes.

[0068] The movable lower mold assembly 6 is installed on the left side of the frame 1; the cake pressing mechanism 7 is installed in the middle of the frame 1; the follow-up powder blocking mechanism 8 is connected to the movable lower mold assembly 6 and the frame 1; the cake receiving mechanism 12 is installed on the lower side of the frame 1 and aligned with the cake pressing mechanism 7;

[0069] The finished product tray unloading and stacking mechanism for automatically unloading and stacking full trays containing powder cakes is installed on the right side of the frame 1;

[0070] The area behind the first transplanting frame 2 of the frame 1 is set as the feeding station; the area where the follow-up powder blocking mechanism 8 is located of the frame 1 is set as the waiting station; the area where the pressing mechanism 7 is located of the frame 1 is set as the pressing station; the area to the left of the pressing mechanism 7 of the frame 1 is set as the powder receiving station.

[0071] In this invention, the continuous empty material tray feeding mechanism first controls the empty material tray to move to the feeding station; then the powder feeding mechanism 5 moves to the right to the powder receiving station, and the movable lower mold assembly 6 also moves to the right along with the powder feeding mechanism 5; until the left side of the movable lower mold assembly 6 moves to the powder receiving station, the middle part of the movable lower mold assembly 6 moves to the pressing station, and the right side of the movable lower mold assembly 6 moves to the waiting station; at this time, the left side of the movable lower mold assembly 6 blocks the bottom of the powder feeding mechanism 5; the middle part of the movable lower mold assembly 6 blocks the bottom of the pressing mechanism 7.

[0072] Subsequently, the continuous empty material tray feeding mechanism pushes the empty material tray at the feeding station to the left onto the active lower mold assembly 6 at the waiting station;

[0073] Furthermore, as the moving lower mold assembly 6 moves to the right, it also controls the follow-up powder blocking mechanism 8 to move to the left, blocking the right side of the pressing mechanism 7, thereby preventing the powder in the powder feeding mechanism 5 from falling from the right side of the pressing mechanism 7 into the empty material tray in the waiting position during subsequent powder pressing operations.

[0074] Then the powder storage mechanism 4 will move the powder, causing the powder to fall into the powder feeding mechanism 5 at the powder receiving station. During the powder receiving process, the powder feeding mechanism 5 will also break up the clumps of powder inside, thereby improving the quality of the powder cake pressing.

[0075] After the powder feeding mechanism 5 completes the set amount of powder receiving operation, the powder storage mechanism 4 stops working. Then, the powder feeding mechanism 5 continues to move to the right and separates from the left side of the movable lower mold assembly 6, and comes into contact with the pressing mechanism 7. Then, the powder in the powder feeding mechanism 5 will fall into the pressing mechanism 7, and the movable lower mold assembly 6 will also collect the powder that is spilled during the movement of the powder feeding mechanism 5.

[0076] Then the powder feeding mechanism 5 returns to the left to the powder receiving position; then the pressing mechanism 7 will press the powder to complete the forming of the powder cake.

[0077] After the powder compact is pressed into shape, the movable lower mold assembly 6 will move the empty material tray at the waiting station to the left until the empty material tray moves to the pressing station and is located below the pressing mechanism 7; at this time, the follow-up powder blocking mechanism 8 will also reset to the right to release the blockage on the right side of the pressing mechanism 7, thereby ensuring that the empty material tray can fit with the pressing mechanism 7 when it moves upward.

[0078] Then the receiving mechanism 12 pushes the empty material tray upward, thereby shortening the distance between the lower side of the pressing mechanism 7 and the bottom of the empty material tray, reducing the probability of the powder cake falling loosely, until the empty material tray completely covers the lower side of the pressing mechanism 7, and then the pressing mechanism 7 pushes the powder cake into the empty material tray.

[0079] Then, the cake receiving mechanism 12 moves the full-load tray filled with powder cakes down back onto the movable lower mold assembly 6; the movable lower mold assembly 6 moves the full-load tray to the right back to the waiting position; then the finished product tray unloading and stacking mechanism lifts the full-load tray, separating it from the movable lower mold assembly 6, and then the movable lower mold assembly 6 resets to the left; at this time, the finished product tray unloading and stacking mechanism moves the full-load tray down and to the right to perform the stacking operation;

[0080] By repeating the above steps, the fully automated production of pressed powder can be achieved.

[0081] The continuous empty material tray feeding mechanism includes a first transfer frame 2 and an alternating feeding mechanism 3; the first transfer frame 2 is located on the right front of the frame 1;

[0082] The alternating feeding mechanism 3 is installed on the first transfer frame 2 and connected to the frame 1;

[0083] The right side of the first transplanting frame 2 is set as the empty material tray moving station;

[0084] The alternating feeding mechanism 3 includes a first cylinder slide assembly 31, a limiting frame 32, a conveying assembly 33, a bidirectional pushing assembly 34, and a lifting assembly; the first cylinder slide assembly 31 is fixedly installed on the upper end of the first transfer frame 2; two limiting frames 32 for storing empty material trays are symmetrically fixedly installed on the left and right sides of the moving end of the first cylinder slide assembly 31; the conveying assembly 33 is installed on the frame 1; the bidirectional pushing assembly 34 is connected to the conveying assembly 33; and the lifting assembly is installed on the upper right side of the first transfer frame 2.

[0085] In this invention, empty material trays are stacked inside the limiting frame 32. The first cylinder slide assembly 31 controls the left and right limiting frames 32 to move alternately to the empty material tray moving position. The lifting assembly also pushes the empty material trays inside the limiting frame 32 at the empty material tray moving position to move upward, thereby enabling the conveying assembly 33 to perform continuous empty material tray conveying operations. At this time, the conveying assembly 33 can drive the empty material trays to flow between the limiting frame 32 and the frame 1. Then, the bidirectional pushing assembly 34 can perform the empty material tray pushing operation.

[0086] The conveying assembly 33 includes a lifting frame 331, a synchronous belt and synchronous pulley transmission assembly 332, a conveying drive motor 333, a first linear guide rail assembly 334, a second cylinder slide assembly 335, and a feeding suction cup 336; the lifting frame 331 is fixedly installed on the upper right side of the frame 1; the two synchronous pulleys of the synchronous belt and synchronous pulley transmission assembly 332 are respectively rotatably installed on the front and rear sides of the left end of the lifting frame 331; the conveying drive motor 333 is fixedly installed on the rear right side of the lifting frame 331; and the output end of the conveying drive motor 333 is fixedly connected to the rear synchronous pulley.

[0087] The guide rail of the first linear guide rail assembly 334 is fixedly installed on the lower left side of the lifting frame 331; the slider of the first linear guide rail assembly 334 is fixedly connected to the synchronous belt of the synchronous belt pulley transmission assembly 332.

[0088] The second cylinder slide assembly 335 is fixedly mounted on the slider of the first linear guide assembly 334; the feeding suction cup 336 is fixedly mounted on the moving end of the second cylinder slide assembly 335; and the feeding suction cup 336 is connected to an external air pump (not shown in the figure) through an air pipe.

[0089] In this invention, the transport drive motor 333 controls the synchronous belt and synchronous pulley transmission assembly 332 to operate, thereby causing the second cylinder slide assembly 335 to move forward along the first linear guide assembly 334 until the loading suction cup 336 moves above the empty material tray. Then, the second cylinder slide assembly 335 drives the loading suction cup 336 to move downward until the loading suction cup 336 contacts the bottom of the empty material tray. Then, the air pump controls the loading suction cup 336 to adsorb and fix the empty material tray. Then, the second cylinder slide assembly 335 and the synchronous belt and synchronous pulley transmission assembly 332 drive the empty material tray to move backward and place the empty material tray at the loading station of the frame 1.

[0090] Subsequently, the lifting component will push all the empty material trays in the limit frame 32 at the empty material tray moving upward, so that the feeding suction cup 336 can always perform empty material tray adsorption operation from the same height.

[0091] The bidirectional pushing assembly 34 includes a first pushing cylinder 341, a second pushing cylinder 342, a lower guide rod 343, an upper guide rod 344, a first push plate 345, a receiving mounting plate 346, and a second push plate 347. The left ends of the lower guide rod 343 and the upper guide rod 344 are both fixedly installed on the lower side of the lifting frame 331. The receiving mounting plate 346 is fixedly installed on the right end of the lower guide rod 343. The first pushing cylinder 341 is fixedly installed on the lower side of the lifting frame 331. The first push plate 345 is fixedly connected to the output end of the first pushing cylinder 341. The first push plate 345 is also slidably connected to the lower guide rod 343.

[0092] The second pusher cylinder 342 is fixedly installed on the left end of the receiving mounting plate 346; the second pusher plate 347 is fixedly connected to the output end of the second pusher cylinder 342; and the second pusher plate 347 is limited and slidably connected to the upper guide rod 344.

[0093] In this invention, after the feeding suction cup 336 places the empty material tray at the feeding station of the frame 1, and waits for the material cake pressing operation to be completed, the first pushing cylinder 341 will push the first pushing plate 345 to move horizontally to the left along the lower guide rod 343. At this time, the first pushing plate 345 will push the empty material tray at the feeding station to the active lower mold assembly 6 at the waiting station.

[0094] When it is necessary to unload all the full-load pallets in the finished product pallet unloading and stacking mechanism, the second pusher cylinder 342 pushes the second pusher plate 347 to move horizontally to the right along the upper guide rod 344. During the movement, the second pusher plate 347 will push all the full-load pallets on the finished product pallet unloading and stacking mechanism to the right away from the finished product pallet unloading and stacking mechanism.

[0095] The lifting assembly includes an empty material tray rigid chain pusher 35, an empty material tray push drive motor 36, a pusher guide rod 37, and a pusher plate 38. The empty material tray rigid chain pusher 35 and the empty material tray push drive motor 36 are both fixedly installed on the upper right side of the first transplanting frame 2. The output end of the empty material tray push drive motor 36 is fixedly connected to the input end of the empty material tray rigid chain pusher 35. The output end of the empty material tray rigid chain pusher 35 is fixedly connected to the bottom of the pusher plate 38. The pusher guide rod 37 is symmetrically fixedly installed on the front and rear sides of the first transplanting frame 2. The pusher plate 38 and the pusher guide rod 37 are in a limited sliding connection.

[0096] The empty material tray rigid chain pusher 35 adopts mature technology in the industry; for example, the pusher rigid chain in application number CN217179395U.

[0097] In this invention, the empty material tray push drive motor 36 controls the operation of the empty material tray rigid chain pusher 35, causing the rigid chain in the empty material tray rigid chain pusher 35 to move upward. The upward movement of the rigid chain will push the push plate 38 to move upward along the push guide rod 37, thereby causing all the empty material trays in the limit frame 32 to move upward together.

[0098] The powder storage mechanism 4 includes a main hopper 41, a first belt conveyor 42, baffle plates 43, and a first powder receiving tray 44; the main hopper 41 and the first belt conveyor 42 are both fixedly installed on the upper left side of the frame 1; the first belt conveyor 42 is located below the main hopper 41; multiple baffle plates 43 are fixedly installed linearly and at equal intervals on the moving end of the first belt conveyor 42; adjacent baffle plates 43 constitute a powder separation chamber;

[0099] The lower end of the main hopper 41 is higher than the upper end of the baffle plate 43;

[0100] Furthermore, a first powder receiving plate 44 for receiving residual powder in the powder separation chamber can be detachably installed on the upper left side of the frame 1;

[0101] In this invention, the powder is poured into the main hopper 41, and then the powder moves along the main hopper 41 into the powder separation chamber. When the pressing operation is required, the first belt conveyor 42 controls multiple baffles 43 to move simultaneously, so that the powder moves from the right side of the first belt conveyor 42 into the powder feeding mechanism 5.

[0102] When the powder separation bin moves to the lower side of the first belt conveyor 42, the residual powder in the powder separation bin will fall into the first powder leakage receiving plate 44, which is convenient for the operator to collect.

[0104] In this invention, the powder receiving and pushing component controls the automatic stirring and carrying component 54 to move between the powder receiving station and the pressing station, thereby realizing continuous powder pressing operation; and the automatic stirring and carrying component 54 can also stir the powder to prevent the powder from clumping.

[0106] In this invention, the first push drive motor 52 controls the operation of the first rigid chain pusher 51, so that the rigid chain of the first rigid chain pusher 51 pushes the automatic stirring bearing assembly 54 to move along the feeding guide rod 53.

[0107] The automatic stirring bearing assembly 54 includes a powder receiving tray 541, a synchronous chain and synchronous sprocket transmission assembly 542, a powder stirring drive motor 543, a commutator 544, a drive shaft 545, a stirring rod 546, and a connecting sleeve 547; the front and rear sides of the powder receiving tray 541 are slidably connected to the feeding guide rod 53; the output end of the first rigid chain pusher 51 is fixedly connected to the middle of the left end of the powder receiving tray 541;

[0108] Multiple drive shafts 545 are linearly and equally spaced along the length of the inner walls of the front and rear of 541.

[0109] A stirring rod 546 is provided between the two front and rear drive shafts 545; the stirring rod 546 is rectangular.

[0110] The connecting sleeve 547 is symmetrically sleeved on the outer end of the stirring rod 546, and the connecting sleeve 547 is slidably connected to the front and rear sides of the stirring rod 546.

[0111] Furthermore, the front and rear connecting sleeves 547 are detachably connected to the front and rear drive shafts 545 respectively by bolts;

[0112] The powder mixing drive motor 543 and the commutator 544 are symmetrically fixedly installed on the front and rear sides of the left end of the powder receiving tray 541; the output end of the powder mixing drive motor 543 is fixedly connected to the input end of the commutator 544; the synchronous chain and synchronous sprocket transmission assembly 542 is symmetrically installed on the front and rear sides of the powder receiving tray 541; one end of the synchronous chain and synchronous sprocket transmission assembly 542 is fixedly connected to the output end of the commutator 544; the other end of the synchronous chain and synchronous sprocket transmission assembly 542 is fixedly connected to the drive shaft 545; through the synchronous chain and synchronous sprocket transmission assembly 542, the commutator 544 and the drive shaft 545 are connected in a transmission manner.

[0113] The lower end of the powder receiving tray 541 is provided with a discharge port to facilitate the movement of internal powder.

[0114] The inner wall of the powder receiving tray 541 is detachably fitted with multiple sheet metal parts for easy cleaning.

[0115] In this invention, the rigid chain of the first rigid chain pusher 51 pushes the powder receiving tray 541 to move along the feeding guide rod 53; during the movement, the powder stirring drive motor 543 controls the commutator 544 to operate, so that the commutators 544 on the front and rear sides drive multiple drive shafts 545 to rotate synchronously, and the drive shafts 545 will drive the connecting sleeve 547 to rotate together; since the stirring rod 546 is rectangular, the connecting sleeve 547 will drive the stirring rod 546 to rotate synchronously, thereby causing the stirring rod 546 to rotate and break up the clumps of powder in the powder receiving tray 541.

[0116] When cleaning the device after the pressing operation is completed, remove the bolts connecting the front and rear connecting sleeves 547 to the front and rear drive shafts 54, and pull the two connecting sleeves 547 along the stirring rod 546 in a direction closer to each other, thereby disconnecting the connection between the stirring rod 546 and the drive shaft 54. At this time, the stirring rod 546 can be taken out and cleaned. Then, the sheet metal of the inner wall of the powder receiving tray 541 is disassembled and cleaned, thereby achieving a comprehensive cleaning of the powder receiving tray 541.

[0117] The movable lower mold assembly 6 includes a third cylinder slide assembly 61, a movable pad 62, a powder receiving tray sealing plate 63, a powder cake sealing plate 64, a second powder leakage receiving tray 66, and a Z-shaped receiving rod 67; the third cylinder slide assembly 61 is fixedly installed in the middle left side of the frame 1; the movable pad 62 is fixedly connected to the moving end of the third cylinder slide assembly 61; the powder receiving tray sealing plate 63 and the powder cake sealing plate 64 are sequentially fixedly installed on the upper left and right sides of the movable pad 62; the installation position of the powder receiving tray sealing plate 63 is higher than that of the powder cake sealing plate 64;

[0118] A powder leakage channel 65 is provided in the middle of the movable pad 62;

[0119] The second powder receiving tray 66 can be detachably installed on the lower left side of the frame 1;

[0120] Z-shaped receiving rods 67 are symmetrically fixedly installed on the front and rear sides of the lower end of the movable pad 62;

[0121] In this invention, the third cylinder slide assembly 61 controls the movement of the movable pad 62, and the powder receiving tray sealing plate 63 can block the discharge port at the lower end of the powder receiving tray 541 to prevent the powder from being moved out from the lower side of the powder receiving tray 541 when the powder receiving tray 541 is performing powder receiving operation; the powder cake sealing plate 64 can block the lower side of the pressing mechanism 7, thereby ensuring the quality of the powder cake pressing.

[0122] Furthermore, when the powder receiving tray 541 moves from the receiving station to the pressing station, the powder that escapes from the discharge port of the powder receiving tray 541 will move into the second powder receiving tray 66 through the powder leakage channel 65. This not only facilitates the collection of powder by the operator, but also ensures the cleanliness of the movable pad 62, reducing the extra workload required for manual cleaning.

[0123] Furthermore, when the movable pad 62 moves, it will also drive the Z-shaped receiving rod 67 to move synchronously. When the Z-shaped receiving rod 67 is in the waiting position, the first push plate 345 can push the empty material tray at the feeding position to the Z-shaped receiving rod 67 in the waiting position, thus facilitating the powder cake receiving operation.

[0124] The pressing mechanism 7 includes a stand 71, a pressing cylinder 72, a pressing guide rod 73, a pressing plate 74, a pressing die head 75, a powder cake forming template 76, and a vibration shaking assembly; the stand 71 is fixedly installed in the middle of the upper end of the frame 1; the pressing cylinder 72 is fixedly installed in the upper end of the stand 71; the output end of the pressing cylinder 72 is fixedly connected to the pressing plate 74; the pressing guide rod 73 is symmetrically fixedly installed on the front and rear sides of the pressing plate 74; the pressing guide rod 73 is slidably connected to the upper end of the stand 71.

[0125] Multiple pressing die heads 75 are fixedly installed at the lower end of the pressing plate 74;

[0126] The powder forming template 76 is fixedly installed in the middle of the frame 1; and the powder forming template 76 is provided with forming grooves 761 that correspond one-to-one with the pressing die head 75;

[0127] The material pressing guide rod 73 is connected to the vibrating material shaking assembly;

[0128] The vibration shaking assembly includes a vibration fixing plate 77, a vibration motor fixing frame 78, a vibration motor 79, a fixing ear plate 710, a vibration shaft 711, and a synchronous transmission assembly 712.

[0130] The vibration motor mounting bracket 78 is fixedly installed on the upper rear side of the vibration mounting plate 77; the vibration motor 79 is fixedly connected to the vibration motor mounting bracket 78;

[0131] The fixed ear plate 710 is symmetrically fixedly installed on the front and rear front sides of the upper left side of the vibration fixing plate 77;

[0132] The front and rear ends of the vibration shaft 711 are rotatably connected to the front and rear fixed lugs 710;

[0133] One end of the synchronous transmission assembly 712 is installed on the rear side of the vibration motor mounting bracket 78 and is fixedly connected to the output end of the vibration motor 79; the other end of the synchronous transmission assembly 712 is installed on the rear fixed ear plate 710 and is fixedly connected to the vibration shaft 711.

[0134] The output end of the vibration motor 79 is connected to the vibration shaft 711 via the synchronous transmission component 712.

[0135] The synchronous transmission assembly 712 adopts a synchronous belt and synchronous belt pulley transmission assembly;

[0136] In this invention, after the powder cake sealing plate 64 moves to the lower end of the powder cake forming template 76, the first rigid chain pusher 51 continues to push the powder receiving tray 541 to the right along the feeding guide rod 53 until the powder receiving tray 541 moves above the powder cake forming template 76. Then, the powder in the powder receiving tray 541 will move from the discharge port at the lower end of the powder receiving tray 541 into the forming groove 761. Then, the powder receiving tray 541 resets to the left. During the reset process, the powder remaining in the powder receiving tray 541 changes from the powder leakage channel 65 to the second powder leakage receiving tray 66.

[0137] Subsequently, the pressing cylinder 72 controls the pressing plate 74 to move downwards following the pressing guide rod 73, thereby causing the pressing die head 75 to squeeze the powder in the forming groove 761, and with the cooperation of the powder cake sealing plate 64, the pressing and forming operation of the powder cake is completed.

[0138] After a single pressing operation is completed, the vibration motor 79 is started. The vibration motor 79 then drives the vibration shaft 711 to rotate synchronously through the synchronous transmission component 712, which causes the vibration fixing plate 77 to vibrate. This, in turn, controls the pressing guide rod 73 to drive multiple pressing dies 75 to vibrate, so that the residual powder on the pressing dies 75 falls into the second powder leakage receiving plate 66 below. This not only reduces the extra workload of manual cleaning, but also ensures the quality of the next pressing.

[0139] The follow-up powder blocking mechanism 8 includes a trigger rod 81, a rocker arm 82, a trigger roller 83, an elastic element 84, a powder blocking plate 85, and a second linear guide rail assembly 86; the trigger rod 81 is symmetrically fixedly installed on the front and rear sides of the lower end of the movable pad 62; the rocker arm 82 is rotatably installed on the front and rear inner walls of the right side of the frame 1; one end of the elastic element 84 is fixedly connected to the rocker arm 82; the other end of the elastic element 84 is fixedly connected to the frame 1.

[0140] The elastic element 84 ensures that the joystick 82 always tends to rotate to the right.

[0141] The elastic element 84 is a tension spring;

[0142] The trigger roller 83 is mounted on the lower end of the rocker arm 82; the upper end of the rocker arm 82 is hinged to the lower end of the powder baffle plate 85.

[0143] The guide rails of the second linear guide rail assembly 86 are symmetrically fixedly installed on the front and rear sides of the upper end of the frame 1; the front and rear sides of the lower end of the powder baffle plate 85 are fixedly connected to the sliders of the front and rear second linear guide rail assemblies 86.

[0144] In this invention, when the movable pad 62 drives the trigger rod 81 to move to the right, the trigger rod 81 will touch the trigger roller 83 at the lower end of the rocker arm 82, thereby controlling the rocker arm 82 to rotate to the left around the hinge point with the frame 1 and stretch the elastic element 84, thereby causing the powder baffle 85 to move horizontally to the left along the second linear guide assembly 86 until the left end of the powder baffle 85 abuts against the right end of the powder cake forming template 76, thereby sealing the right side area of ​​the powder cake forming template 76 and preventing the powder from moving into the empty material tray;

[0145] The cake receiving mechanism 12 includes a cross frame 121, a cake receiving drive cylinder 122, an I-frame 123, and cake receiving suction cups 124. The cross frame 121 is fixedly installed on the lower left side of the frame 1. The cake receiving drive cylinder 122 is fixedly installed at the lower end of the cross frame 121. The I-frame 123 is fixedly connected to the output end of the cake receiving drive cylinder 122. Multiple cake receiving suction cups 124 are fixedly installed at the upper end of the I-frame 123. The cake receiving suction cups 124 are connected to an air pump (not shown in the figure) through an air pipe.

[0146] In this invention, the movable pad 62 drives the Z-shaped receiving rod 67 to pull the empty material tray of the waiting station to the pressing station. At this time, the trigger rod 81 will also separate from the trigger roller 83. Then the elastic element 84 drives the rocker arm 82 to rotate to the right, so that the powder baffle plate 85 resets to the right and releases the blockage on the right side of the powder forming template 76.

[0147] Then the cake receiving drive cylinder 122 pushes the I-frame 123 upward until the cake receiving suction cup 124 contacts the lower end of the empty material tray; then the cake receiving suction cup 124 adsorbs and fixes the empty material tray; and the I-frame 123 continues to move upward, shortening the distance between the lower end of the cake forming template 76 and the bottom of the empty material tray.

[0148] Until the empty material tray completely covers the lower side of the powder cake forming template 76, the pressing cylinder 72 then pushes the pressing die head 75 down, so that the pressing die head 75 pushes the powder cake formed in the forming groove 761 into the empty material tray.

[0149] Subsequently, the cake receiving drive cylinder 122 drives the I-frame 123 to reset downwards, thereby causing the full-load material tray loaded with the cake to move back onto the Z-shaped receiving rod 67;

[0150] The finished product tray unloading and stacking mechanism includes a tray receiving mechanism 9, a tray feeding mechanism 10, and a tray stacking mechanism 11; the tray receiving mechanism 9 and the tray feeding mechanism 10 are both installed on the lower right side of the frame 1; the tray stacking mechanism 11 is located on the right side of the frame 1.

[0151] In this invention, the receiving mechanism 9 controls the separation of the full-loaded material tray in the waiting position from the Z-shaped receiving rod 67, and drives the full-loaded material tray to move down to the feeding mechanism 10. Then the feeding mechanism 10 controls the full-loaded material tray to move to the right to the position of the material tray stacking mechanism 11. Then the material tray stacking mechanism 11 can automatically stack the full-loaded material tray.

[0152] The receiving mechanism 9 includes a vertical lifting assembly and a receiving plate 94; the vertical lifting assembly is installed on the lower side of the frame 1; the receiving plate 94 is connected to the vertical lifting assembly;

[0153] The vertical lifting assembly includes a second rigid chain pusher 91, a second push drive motor 92, and a receiving guide rod 93; the second rigid chain pusher 91 and the second push drive motor 92 are both fixedly installed on the lower side of the frame 1; the output end of the second push drive motor 92 is fixedly connected to the input end of the second rigid chain pusher 91.

[0154] The output end of the second rigid chain pusher 91 is fixedly connected to the receiving plate 94; the receiving guide rods 93 are symmetrically fixedly installed on the lower front and rear sides of the frame 1; and the receiving plate 94 and the receiving guide rods 93 are in a limited sliding connection.

[0155] In this invention, after the Z-shaped receiving rod 67 moves the full-loaded material tray back to the waiting position, the second push drive motor 92 controls the operation of the second rigid chain pusher 91, so that the second rigid chain pusher 91 pushes the receiving plate 94 to move upward along the receiving guide rod 93. During the movement, the lower end of the receiving plate 94 will contact the lower end of the full-loaded material tray and separate it from the Z-shaped receiving rod 67.

[0156] Then the Z-shaped receiving rod 67 moves to the left, at which point the second rigid chain pusher 91 can drive the full-load material tray to move downward until the lower end of the full-load material tray separates from the receiving plate 94 and is transferred to the feeding mechanism 10.

[0157] The tray feeding mechanism 10 includes a second belt conveyor 101, a guide frame 102, and guide rollers 103; the second belt conveyor 101 is fixedly installed on the lower right side of the frame 1; the guide frame 102 is symmetrically fixedly installed on the front and rear right sides of the frame 1; multiple guide rollers 103 are linearly and equally spaced and rotatably installed inside the guide frame 102.

[0158] The distance between the front and rear guide frames 102 is the same as the width of the full-load tray;

[0159] An L-shaped baffle for preventing the movement of a fully loaded material tray is fixedly installed at the right end of the second belt conveyor 101;

[0160] In this invention, when the second rigid chain pusher 91 drives the full-loaded tray to move downward, the full-loaded tray will move to the moving end on the left side of the second belt conveyor 101 and separate from the receiving plate 94; then the second belt conveyor 101 drives the full-loaded tray to move to the right along the guide roller 103 until the full-loaded tray moves to the position of the tray stacking mechanism 11, and then the full-loaded tray stacking operation can be carried out.

[0161] The material tray stacking mechanism 11 includes a second transfer frame 111, a bidirectional screw slide module 112, a main moving plate 113, a fourth cylinder slide module 114, a unidirectional screw slide module 115, a lifting plate 116, and a partition plate 117; the second transfer frame 111 is located on the right side of the frame 1;

[0162] The bidirectional screw slide module 112 is fixedly installed on the upper end of the second transplanter 111; the main moving plate 113 is symmetrically fixedly installed on the front and rear moving ends of the bidirectional screw slide module 112.

[0163] The fourth cylinder slide module 114 is fixedly installed on the upper end of the main moving plate 113; the one-way screw slide module 115 is fixedly connected to the moving end of the fourth cylinder slide module 114.

[0164] The lifting plate 116 is fixedly connected to the moving end of the one-way screw slide module 115; multiple partition plates 117 are fixedly installed at equal intervals along the height direction at the close ends of the two lifting plates 116; the distance between adjacent partition plates 117 is the same as the height of a full-load tray.

[0165] In this invention, when the second belt conveyor 101 drives the full-loaded material tray to move to the right along the guide roller 103 to the lower area between the front and rear lifting plates 116; and the front and rear ends of the full-loaded material tray will be inserted into the lowest partition plate 117 between the front and rear lifting plates 116.

[0166] Subsequently, the one-way screw slide module 115 controls the lifting plate 116 to move upward, thereby causing the partition plate 117 to drive the full-load tray to move upward.

[0167] Then, after the next full-load tray moves to the lower area between the front and rear lifting plates 116, the front and rear fourth cylinder slide modules 114 push the one-way screw slide module 115 to move in a direction away from each other, thereby separating the partition plate 117 from the upper full-load tray. At this time, the upper full-load tray will be stacked on top of the lower full-load tray. Then, the one-way screw slide module 115 controls the lifting plate 116 to reset downwards. Then, the fourth cylinder slide module 114 pulls the one-way screw slide module 115 to reset, so that the partition plate 117 is reinserted into the front and rear ends of the lower full-load tray. Then, the one-way screw slide module 115 drives the lifting plate 116 to move upwards, thereby moving the full-load trays that are now stacked upwards together.

[0168] Then repeat the above operation until all partition plates 117 are evenly covered with full-load trays;

[0169] The second pusher cylinder 342 will push the receiving mounting plate 346 to move horizontally to the right along the upper guide rod 344. During the movement, the receiving mounting plate 346 will push all the full-loaded material trays except the bottom layer in the lifting plate 116 to the right away from the partition plate 117, so that the material cakes in the full-loaded material trays can continue to undergo subsequent processing.

[0170] Example 2: In some embodiments, such as Figures 1-13 As shown, in a preferred embodiment of the present invention, a method of using a powder compact forming machine includes the following steps:

[0172] Step 2: The continuous empty material tray feeding mechanism pushes the empty material tray at the feeding station to the left onto the movable lower mold assembly 6; and while the movable lower mold assembly 6 moves to the right, it controls the follow-up powder blocking mechanism 8 to move to the left, blocking the right side of the pressing mechanism 7.

[0173] Step 3: The powder storage mechanism 4 moves the powder, causing it to fall into the powder feeding mechanism 5. During the powder receiving process, the powder feeding mechanism 5 will also break up any clumps of powder inside. After the powder feeding mechanism 5 has completed the set amount of powder receiving, the powder storage mechanism 4 stops working. Then, the powder feeding mechanism 5 continues to move to the right and separates from the left side of the movable lower mold assembly 6, and comes into contact with the pressing mechanism 7. Then, the powder in the powder feeding mechanism 5 will fall into the pressing mechanism 7, and the movable lower mold assembly 6 will also collect the powder that is spilled during the movement of the powder feeding mechanism 5.

[0174] Step 4: The powder feeding mechanism 5 returns to its original position to the left; the pressing mechanism 7 then presses the powder to form the powder cake.

[0175] Step 5: After the powder compact is pressed and formed, the movable lower mold assembly 6 will drive the empty material tray to move to the left until the empty material tray moves to the lower side of the pressing mechanism 7; the follow-up powder blocking mechanism 8 will also reset to the right to release the blockage on the right side of the pressing mechanism 7.

[0176] Step 6: The receiving mechanism 12 pushes the empty material tray upward until the empty material tray completely covers the lower side of the pressing mechanism 7, and the pressing mechanism 7 pushes the powder cake into the empty material tray;

[0177] Step 7: The receiving mechanism 12 moves the full-load tray filled with powder cakes back down to the movable lower mold assembly 6; the movable lower mold assembly 6 moves the full-load tray to the right to the position of the finished product tray unloading and stacking mechanism; then the finished product tray unloading and stacking mechanism lifts the full-load tray, separating it from the movable lower mold assembly 6, and then the movable lower mold assembly 6 resets to the left; the finished product tray unloading and stacking mechanism moves the full-load tray down and to the right to perform the stacking operation.

10. A method of use with the powder compacting machine of claim 1, comprising: Includes the following steps: Step 1: The continuous empty material tray feeding mechanism first controls the empty material tray to move to the feeding station; the powder feeding mechanism (5) moves to the right to the powder receiving station, and the movable lower mold assembly (6) moves to the right along with the powder feeding mechanism (5); Step 2: The continuous empty material tray feeding mechanism pushes the empty material tray at the feeding station to the left to the movable lower mold assembly (6); and while the movable lower mold assembly (6) moves to the right, it controls the follow-up powder blocking mechanism (8) to move to the left to block the right side of the pressing mechanism (7); Step 3: The powder storage mechanism (4) moves the powder, causing it to fall into the powder feeding mechanism (5). During the powder receiving process, the powder feeding mechanism (5) will also break up any clumps of powder inside. After the powder feeding mechanism (5) has completed the set amount of powder receiving, the powder storage mechanism (4) stops working. Then the powder feeding mechanism (5) continues to move to the right and separates from the left side of the movable lower mold assembly (6), and comes into contact with the pressing mechanism (7). Then the powder in the powder feeding mechanism (5) will fall into the pressing mechanism (7), and the movable lower mold assembly (6) will also collect the powder that is spilled during the movement of the powder feeding mechanism (5). Step 4: The powder feeding mechanism (5) resets to the left; the pressing mechanism (7) then presses the powder to complete the forming of the powder cake; Step 5: After the powder cake is pressed and formed, the movable lower mold assembly (6) will drive the empty material tray to move to the left until the empty material tray moves to the lower side of the pressing mechanism (7); the follow-up powder blocking mechanism (8) will also reset to the right to release the blockage on the right side of the pressing mechanism (7); Step 6: The receiving mechanism (12) pushes the empty material tray upward until the empty material tray completely covers the lower side of the pressing mechanism (7), and the pressing mechanism (7) pushes the powder cake into the empty material tray; Step 7: The receiving mechanism (12) moves the full-load tray filled with powder cakes back down to the movable lower mold assembly (6); the movable lower mold assembly (6) moves the full-load tray to the right to the position of the finished product tray unloading and stacking mechanism; then the finished product tray unloading and stacking mechanism will lift the full-load tray, so that the full-load tray is separated from the movable lower mold assembly (6), and then the movable lower mold assembly (6) resets to the left; the finished product tray unloading and stacking mechanism moves the full-load tray down and to the right to perform the stacking operation.
