Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of powder production related equipment, and in particular to an extraction device. BACKGROUND

[0002] With the industrialization process of energy, chemical, medical, food and other industries, the powder industry has experienced rapid development in the automation degree from production to transportation. During the process of powder from production to transportation, the pollution of powder to the environment is a major problem to be solved, especially during powder transportation.

[0003] As for the powder transportation method, it is mainly divided into dry conveying method and wet conveying method, among which the dry conveying method is more commonly used. The dry conveying method can be further divided into mechanical force conveying, pneumatic conveying or container conveying methods. Mechanical force conveying is a method of conveying powder materials by mechanical force of mechanical devices (such as belt conveyors, chain conveyors, screw conveyors, vibrating conveyors or bucket elevators, etc.). Pneumatic conveying is a method of conveying powder materials in a pipeline by means of air flow. Container conveying is a method of conveying powder by means of special conveying tools (such as special tank trucks or containerized containers, etc.).

[0004] In related technologies, in order to improve the powder conveying efficiency and avoid the problem of dust leakage, and to ensure the health of on-site workers, for example, CN217807560U discloses a mobile vehicle-mounted powder collecting system, which comprises a negative pressure feeding module, a positive pressure conveying module and a vacuum extraction module. The negative pressure feeding module is used to suck powder by negative pressure. The conveying module is connected with the negative pressure feeding module and is used to convey the powder sucked in the negative pressure feeding module to an external powder tank truck. The vacuum extraction module is connected with the negative pressure feeding module and the positive pressure conveying module, and is used to extract vacuum from the negative pressure feeding module and convey the extracted air to the positive pressure conveying module.

[0005] For another example, CN111301731A discloses a lithium hydroxide micro-powder vacuum extraction and bagging device, which comprises a vacuum material suction gun corresponding to a semi-finished material bag, a dust collector, and a vacuum pump communicating with the dust collector. The vacuum material suction gun communicates with the inlet of the dust collector. It also includes a finished material bag corresponding to the outlet of the dust collector.

[0006] For example, CN113620062A discloses a negative pressure dust-free feeding and quantitative discharging device, which comprises a tank body and an upper cover. The outer side of the tank body is provided with a weighing platform, a suction gun, a negative pressure fan, a ventilation hard pipe and a suction hose. The upper cover is provided with an air-material separation assembly and a respirator. The tank body is internally provided with an auger shaft and externally provided with a driving assembly. The auger shaft is provided with a positioning assembly, auger blades and a connecting rod. One end of the connecting rod is connected with a scraping plate. The negative pressure fan forms negative pressure in the tank body, and then the suction gun can realize dust-free feeding. The air-material separation assembly prevents the material from being sucked out of the tank body by the negative pressure fan. The driving assembly, the auger shaft, the auger blades and the connecting rod can realize quantitative discharging, and the material can also be crushed.

[0007] It should be noted that after the creation of the present scheme, the following technical documents are provided for reference:

[0008] 1. CN104670904A - A negative pressure feeding device;

[0009] 2. CN107323703A - Dust-free powder filling device and method.

[0010] However, the above-mentioned comparative documents do not solve the following two problems:

[0011] 1) For powdery materials with small particle size, the powdery materials in the barrel are sucked by pneumatic conveying. The powdery materials are prone to be left on the inner wall of the cylinder, and the materials cannot be quickly and reliably extracted from the barrel;

[0012] 2) Manual grabbing of the suction gun is required for suction operation, that is, manual intervention is required for the suction operation, and the labor intensity is high.

[0013] Therefore, there is an urgent need for an extraction device that can quickly extract materials and has low labor intensity. SUMMARY

[0014] The purpose of the present disclosure is to provide an extraction device that can quickly extract materials and has low labor intensity.

[0024] In one embodiment, the lifting drive includes a drive source, a first sprocket, a second sprocket, and a transmission chain. The drive source is fixed at a first height position of the frame. The first sprocket is connected to the power shaft of the drive source. The second sprocket is rotatably connected to a second height position of the frame. The transmission chain is connected to the first sprocket and the second sprocket respectively. The movable frame is connected to the transmission chain.

[0025] In one embodiment, the extraction device further includes a first guide slide, the frame having a guide hole, the first guide slide passing through the guide hole and slidably connected to the frame, and the first guide slide being fixedly connected to the transmission chain and the movable frame respectively.

[0026] In one embodiment, the extraction device further includes a second guide slide, which is fixedly connected to the frame. The second guide slide is provided with an auxiliary guide rod, and the movable frame is provided with a guide sleeve. The guide sleeve is sleeved inside the auxiliary guide rod and slidably connected to the auxiliary guide rod.

[0027] In one embodiment, the translation drive includes a servo motor, a first support base, a lead screw, a nut, and a second support base. The servo motor is fixed to the movable frame. The first support base and the second support base are both mounted on the movable frame. The first support base has a first rotating hole, and the second support base has a second rotating hole.

The tumbling cylinder is mounted on the cylinder frame, and the hammer is connected to the power output end of the tumbling cylinder.

[0031] Compared with the prior art, this disclosure has at least the following advantages:

[0032] 1. The aforementioned extraction device has its control mechanism electrically connected to the control terminals of the negative pressure component, the lifting drive component, the translation drive component, the rotation drive component, and the vibration mechanism. When it is necessary to extract or convey material from the hopper on the rotating weighing platform, the control mechanism first controls the lifting drive component and the translation drive component to operate. Since the translation drive component is fixedly mounted on the power output terminal of the lifting drive component, there is an angle between the power output direction of the lifting drive component and the power output direction of the translation drive component. The suction gun is connected to the power output terminal of the translation drive component to drive the suction gun to move from outside the hopper to... The material is positioned within the hopper; then, the control mechanism controls the negative pressure component and the rotary drive component to operate. The negative pressure component draws material in as the hopper rotates with the rotary weighing base. Even if the hopper rotates one full revolution relative to the suction gun, the suction gun can effectively draw material from the current height position of the hopper. Then, the control mechanism again controls the lifting drive component to lower the suction gun to a predetermined height. Simultaneously, the control mechanism controls the vibration mechanism to vibrate the outer wall of the hopper, thereby drawing material from the next height position. This process of automatic powder material suction is repeated.

[0033] 2. When the suction gun descends to the predetermined height to suction material, the vibration mechanism vibrates against the outer wall of the material barrel, which avoids the situation where powder remains on the inner wall of the material barrel or accumulates in the middle and cannot be sucked up temporarily, thus improving the material extraction efficiency and enabling fast and thorough material suction.

[0034] 3. Through the combined action of the lifting drive component and the translation drive component, the suction gun is moved in the vertical plane. At the same time, the rotation drive component drives the rotating weighing seat to rotate relative to the fixed seat, which in turn drives the material bucket to rotate relative to the fixed seat. In addition, the vibration mechanism acts on the outer wall of the material bucket. No manual intervention is required in the middle, which greatly reduces the intensity of manual labor.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0047] like Figures 1 to 3As shown, one embodiment of the extraction device 10 includes a suction mechanism 100, a material bin 200, a weighing platform 300, a frame 400, a moving drive mechanism 500, a vibration mechanism 600, and a control mechanism 700. The suction mechanism 100 includes a suction gun 110 and a negative pressure assembly (not shown). The suction gun 110 is connected to one end of the negative pressure assembly, allowing the negative pressure assembly to suction material through the suction chamber. The material bin 200 is placed on the weighing platform 300.

[0048] In one embodiment, the moving drive mechanism 500 includes a lifting drive assembly 510 and a translation drive assembly 520. The lifting drive assembly 510 is mounted on the frame 400, and the translation drive assembly 520 is fixedly mounted to the power output end of the lifting drive assembly 510. There is an angle between the power output direction of the lifting drive assembly 510 and the power output direction of the translation drive assembly 520. The suction gun 110 is connected to the power output end of the translation drive assembly 520.

[0049] In one embodiment, the included angle is 60° to 120°. In this embodiment, the included angle is 90°. Specifically, the power output direction of the lifting drive assembly 510 is parallel to the Z-axis direction, and the power output direction of the translation drive assembly 520 is parallel to the X-axis direction.

[0050] In one embodiment, the weighing platform 300 includes a fixed base 310, a rotary weighing seat 320, and a rotary drive assembly 330. The rotary drive assembly 330 is mounted on the fixed base 310, and its power output end is connected to the rotary weighing seat 320 to drive the rotary weighing seat 320 to rotate relative to the fixed base 310. The rotary weighing seat 320 is supported on the material bin 200 and is used to weigh the material bin 200.

[0051] In one embodiment, the vibration mechanism 600 is mounted on the fixed base 310 and is used to vibrate the outer wall of the material bucket 200. The control mechanism 700 is electrically connected to the control terminals of the negative pressure component, the lifting drive component 510, the translation drive component 520, the rotation drive component 330, and the vibration mechanism 600.

[0052] The aforementioned extraction device 10 and control mechanism 700 are electrically connected to the control terminals of the negative pressure component, the lifting drive component 510, the translation drive component 520, the rotation drive component 330, and the vibration mechanism 600, respectively. When it is necessary to extract or deliver material from the material bin 200 on the rotating weighing seat 320, the control mechanism 700 first controls the lifting drive component 510 and the translation drive component 520 to operate. Since the translation drive component 520 is installed and fixed to the power output terminal of the lifting drive component 510, there is an angle between the power output direction of the lifting drive component 510 and the power output direction of the translation drive component 520. The suction gun 110 is connected to the power output terminal of the translation drive component 520 to drive the suction gun 110 from the material bin 200. The material is moved from the external position to the suction position inside the material hopper 200. Then, the control mechanism 700 controls the negative pressure component to work, and simultaneously controls the rotary drive component 330 to work. In this way, the negative pressure component sucks up the material as the material hopper 200 rotates with the rotary weighing base 320. Even if the current height position of the material hopper 200 rotates one revolution relative to the suction gun 110, the suction gun 110 can effectively suck up the material at the current height position of the material hopper 200. Then, the control mechanism 700 controls the lifting drive component 510 to move again, so that the suction gun 110 descends to the predetermined height. At the same time, the control mechanism 700 controls the vibration mechanism 600 to vibrate against the outer wall of the material hopper 200, thereby sucking up the material at the next height position. Then, the above suction operation is repeated to realize the automatic suction of powder.

[0053] When the suction gun 110 descends to a predetermined height to suction material, the vibration mechanism 600 vibrates against the outer wall of the material bucket 200, preventing powder from remaining on the inner wall of the material bucket 200 or accumulating in the middle and being unable to be suctioned temporarily, thus improving the material extraction efficiency. At the same time, it can achieve fast and thorough material suction. Through the combined action of the lifting drive component 510 and the translation drive component 520, the suction gun 110 is driven to move in the vertical plane. At the same time, the rotation drive component 330 drives the rotating weighing seat 320 to rotate relative to the fixed seat 310, which in turn drives the material bucket 200 to rotate relative to the fixed seat 310. With the vibration mechanism 600 vibrating against the outer wall of the material bucket 200, no manual intervention is required, greatly reducing the intensity of manual labor.

[0054] It should be noted that the rotary weighing stand 320 has a weighing function, and the structure related to the weighing function of the rotary weighing stand 320 is prior art, which will not be described in detail in this application.

[0055] like Figures 1 to 3As shown, in one embodiment, the lifting drive assembly 510 includes a lifting drive component 512 and a movable frame 514. The lifting drive component 512 is mounted and fixed on the frame 400, and the movable frame 514 is slidably connected to the frame 400. The movable frame 514 is connected to the power output end of the lifting drive component 512, so that the lifting drive component 512 drives the movable frame 514 to slide relative to the frame 400. In this embodiment, the lifting drive component 512 drives the movable frame 514 to slide relative to the frame 400 in a direction parallel to the Z-axis.

[0056] like Figures 1 to 3 As shown, in one embodiment, the translation drive assembly 520 includes a translation drive member 522, a movable tray 524, and a suction gun arm 526. The translation drive member 522 is mounted on the movable frame 514, and the movable tray 524 is slidably connected to the movable frame 514. The movable tray 524 is connected to the power output end of the translation drive member 522, causing the translation drive member 522 to drive the movable tray 524 to slide relative to the movable frame 514. The suction gun arm 526 is mounted and fixed to the side of the movable tray 524 opposite to the movable frame 514, and the suction gun 110 is fixedly connected to the suction gun arm 526. In this embodiment, the translation drive member 522 drives the movable tray 524 to slide relative to the movable frame 514 along a direction parallel to the X-axis. Furthermore, two sliders 5242 protrude from the lower part of the movable pallet 524, and two guide rails 5142 protrude from the movable frame 514. The two sliders are slidably connected to the two guide rails in a one-to-one correspondence, allowing the movable pallet 524 to slide more smoothly onto the movable frame 514. Furthermore, the suction gun arm 526 is fixed above the movable pallet 524. The suction gun 110 is fixedly connected to one end of the suction gun arm 526 to avoid interference between the suction gun 110 and the frame 400.

[0057] like Figures 1 to 3 As shown, further, the suction gun arm 526 includes an arm body 5262, a clamping block 5264, and a fixing member (not shown). The clamping block 5264 is fixedly connected to the arm body 5262 by the fixing member, so that the clamping block 5264 and the arm body 5262 together form a receiving groove 5263. The suction gun 110 passes through the receiving groove 5263, so that the suction gun 110 is fixed on the suction gun arm 526. In this embodiment, the receiving groove 5263 includes a first receiving groove opened in the arm body 5262 and a second receiving groove opened in the clamping block 5264. The second receiving groove communicates with the first receiving groove. Specifically, the clamping block 5264 has a connecting hole, and the end of the arm body 5262 has a screw hole. The fixing member passes through the connecting hole, and one end of the fixing member is located in the screw hole and screwed to the arm body 5262, so that the clamping block 5264 and the arm body 5262 are detachably connected.

[0058] like Figures 1 to 3As shown, in one embodiment, the lifting drive component 512 includes a drive source 5122, a first sprocket 5124, a second sprocket 5126, and a transmission chain (not shown). The drive source 5122 is fixed at a first height position on the frame 400. The first sprocket 5124 is connected to the power shaft of the drive source 5122. The second sprocket 5126 is rotatably connected to a second height position on the frame 400. The transmission chain is connected to both the first sprocket 5124 and the second sprocket 5126. The movable frame 514 is connected to the transmission chain. In this embodiment, when the drive source 5122 drives the first sprocket 5124 to rotate, the first sprocket 5124 drives the second sprocket 5126 to rotate relative to the frame 400 via the transmission chain. The transmission chain also drives the movable frame 514 to slide relative to the frame 400. It can be understood that the drive source 5122 can be a motor or an electric cylinder.

[0059] like Figures 1 to 3 As shown, in one embodiment, the extraction device 10 further includes a first guide slide 518. The frame 400 has a guide slide hole 402. The first guide slide 518 passes through the guide slide hole 402 and is slidably connected to the frame 400. The first guide slide 518 is fixedly connected to the transmission chain and the movable frame 514, so that the transmission chain is connected to the movable frame 514 through the first guide slide 518. Furthermore, the first guide slide 518 passing through the guide slide hole 402 and being slidably connected to the frame 400 allows the first guide slide 518 to drive the movable frame 514 to slide smoothly relative to the frame 400. In this embodiment, the guide slide hole 402 is located on the top plate 402 of the frame 400.

[0060] like Figures 1 to 3 As shown, the first guide rail 518 further includes a lifting support rod 5182 and a seat plate 5184 connected to each other. The lifting support rod 5182 passes through the guide rail hole 402 and is slidably connected to the frame 400. The seat plate 5184 and the movable frame 514 are located on both sides of the top plate 402, respectively. See also... Figure 4 The base plate 5184 has a clearance hole 822 and a fixed plate 5185 protruding from it. The fixed plate is located near the clearance hole. The transmission chain passes through the clearance hole and is fixed to the fixed plate, so that the transmission chain can drive the base plate to move up and down. At the same time, the base plate drives the movable frame 514 to slide relative to the frame 400 through the lifting support rod 5182.

[0061] like Figures 1 to 3 As shown, furthermore, there are multiple lifting support rods 5182 and multiple guide holes 402. Multiple lifting support rods 5182 are correspondingly inserted into multiple guide holes 402, making the sliding of the first guide frame 518 relative to the frame 400 more stable. See also... Figure 4Furthermore, the first guide slide 518 also includes a reinforcing column 5186. The top plate 402 has a reinforcing guide hole 4022. The reinforcing column passes through the reinforcing guide hole and is slidably connected to the top plate 402. The two ends of the reinforcing column are respectively connected to the seat plate 5184 and the movable frame 514, so that the first guide slide 518 has good structural strength.

[0062] like Figure 4 and Figure 5 As shown, in one embodiment, the extraction device 10 further includes a second guide slide 900, which is fixedly connected to the frame 400. The second guide slide 900 is provided with an auxiliary guide rod 910, and the movable frame 514 is provided with a guide sleeve 514a. The guide sleeve is sleeved inside the auxiliary guide rod 910 and slidably connected to the auxiliary guide rod 910, so that the movable frame 514 can slide better along the predetermined direction.

[0063] like Figure 4 and Figure 5 As shown, in one embodiment, the translation drive 522 includes a servo motor 522a, a first support 522b, a lead screw (not shown), a nut 522c, and a second support 522d. The servo motor 522a is fixed to the movable frame 514. The first support 522b and the second support 522d are both mounted on the movable frame 514. The first support 522b has a first rotating hole, and the second support 522d has a second rotating hole. The lead screw passes through the first rotating hole and the second rotating hole, and is rotatably connected to the first support 522b and the second support 522d, respectively. One end of the lead screw is connected to the power output shaft of the servo motor 522a. The nut 522c is sleeved on the lead screw and screwed to the lead screw. The nut 522c is connected to the movable support plate 524. When the servo motor 522a drives the lead screw to rotate relative to the first support 522b and the second support 522d respectively, the lead screw rotates relative to the nut 522c, causing the nut 522c to drive the movable tray 524 to slide relative to the movable frame 514.

[0064] like Figures 1 to 3 As shown, in one embodiment, the fixed base 310 has a connecting through hole 302. The rotary drive assembly 330 includes a rotary power component 332 and a bearing seat 334. The rotary power component 332 is installed below the fixed base 310. The outer ring of the bearing seat 334 passes through the connecting through hole 302. The inner ring of the bearing seat 334 is sleeved on the rotating shaft of the rotary power component 332. The rotating shaft of the rotary power component 332 is fixedly connected to the rotary weighing base 320, so that the rotating shaft of the rotary power component 332 is rotatably connected to the fixed base 310, and the rotating shaft of the rotary power component 332 drives the rotary weighing base 320 to rotate relative to the fixed base 310.

[0065] like Figures 1 to 3As shown, in one embodiment, the vibration mechanism 600 includes a cylinder frame 610, a vibration cylinder 620, and a hammer 630. One end of the cylinder frame 610 is connected to the fixed base 310, and the cylinder frame 610 is disposed adjacent to the outer side of the material barrel 200. The vibration cylinder 620 is mounted on the cylinder frame 610, and the hammer 630 is connected to the power output end of the vibration cylinder 620, causing the vibration cylinder 620 to drive the hammer 630 to reciprocate, thereby periodically vibrating the outer wall of the material barrel 200 to prevent powder from remaining on the inner wall of the material barrel 200, thus allowing the suction gun to better suck up the powder. Further, the time of each cycle of the reciprocating motion of the vibration cylinder 620 is the first time, and the rotation cycle of the material barrel 200 relative to the fixed base 310 with the rotating weighing seat 320 is the second time. The first time is equal to 0.1 to 0.2 times the second time. In this embodiment, the first time is equal to 0.1 times the second time, that is, for every 36° rotation of the material bucket 200 relative to the fixed base 310 with the rotating weighing base 320, the vibrating cylinder 620 completes one vibration action on the material bucket 200. Thus, during one rotation of the material bucket, the vibrating cylinder completes 10 vibration actions on the material bucket, ensuring that the residual powder on the circumferential wall of the material bucket 200 is effectively vibrated and separated from the bucket wall. In this embodiment, the vibrating cylinder 620 vibrates multiple height circumferential positions of the material bucket, which are spaced apart along the height of the material bucket. When the suction gun finishes suctioning the powder at the first height circumferential position of the material bucket, the vibrating cylinder 620 drives the hammer to complete one rotation of the third height circumferential position, and the suction gun 110 begins to descend to a predetermined height, i.e., the second height circumferential position, from the first height circumferential position. When the suction gun 110 is at the second height circumferential position, the vibrating cylinder 620 repeats the above steps, while the material bucket 200 rotates relative to the fixed base 310 with the rotating weighing seat 320. The third height circumferential position is greater than the first height circumferential position, and the first height circumferential position is greater than the second height circumferential position. In this embodiment, the vibrating cylinder 620 can always be at the third height circumferential position.

[0066] It is understandable that the oscillating cylinder 620 is not limited to always being at the third height circumferential position. For example, the oscillating cylinder 620 can start from the third height circumferential position and descend in sync with the descending steps of the suction gun. Figure 6 and Figure 7As shown, the cylinder frame 610 further includes a telescopic drive member 612, a cylinder frame body 614, and a support frame 616. The telescopic drive member 612 is mounted on the fixed base 310, and the support frame 616 is slidably connected to the cylinder frame body 614. The cylinder frame body 614 is connected to the fixed base 310. The telescopic drive member 612 is mounted on the cylinder frame body 614, and its power output end is connected to the support frame 616 to drive the support frame 616 to slide relative to the cylinder frame body 614. A vibration cylinder 620 is mounted and fixed on the support frame 616, making its height position relative to the fixed base adjustable, thereby enabling the vibration cylinder 620 to vibrate at different height positions of the material bucket. In this embodiment, the cylinder frame body 614 is sleeved on the outer peripheral wall of the support frame 616 and slidably connected to the cylinder frame body 614. Specifically, a sliding hole 6142 is provided at the end of the cylinder frame body 614 away from the fixed seat 310. Multiple guide ribs (not shown) are spaced circumferentially along the inner wall of the sliding hole. Multiple guide grooves are provided on the outer peripheral wall of the support frame 616, with each guide rib corresponding to one of the guide grooves, ensuring the support frame 616 is reliably slidably connected to the cylinder frame body 614 within the sliding hole. Furthermore, when the suction gun arm 526 descends a predetermined height relative to the material container 200, the telescopic drive member 612 drives the support frame 616 to descend a predetermined height relative to the cylinder frame body 614, allowing the vibration cylinder 620 to effectively strike the material container 200. It is understandable that when the suction gun 110 first sucks up the powder, the height of the vibrating cylinder 620 relative to the fixed base 310 is greater than or equal to the height of the suction gun 110 relative to the fixed base 310, so that the vibrating cylinder 620 can better knock on the powder on the inner wall of the material barrel 200, thereby enabling the suction gun to better suck up the powder in the material barrel.

[0067] Furthermore, a first infrared sensor is provided on the top plate, and a second infrared sensor corresponding to the first infrared sensor is provided on the movable frame. The first and second infrared sensors are used together to detect the distance between the movable frame and the top plate, so as to detect the real-time height position of the suction gun 110. Both the first and second infrared sensors are electrically connected to the control mechanism. The control mechanism controls the extension length of the telescopic drive component according to the real-time height of the suction gun, so that the height position of the hammer head acting on the material barrel of the vibrating cylinder 620 changes in real time according to the height position of the suction gun, thereby realizing automatic control of the vibrating cylinder and improving the automation of the extraction device 10. In this embodiment, the distance between the suction end of the suction gun and the fixed seat is less than or equal to the distance between the vibrating cylinder and the fixed seat, so that the vibrating cylinder can better match the suction position of the suction end of the suction gun for timely adjustment, thereby improving the effectiveness of the vibrating action of the vibrating cylinder. In this embodiment, the control end of the telescopic drive component is electrically connected to the control mechanism. Furthermore, the control mechanism can be a touch panel display, and the user can preset the control parameters of the control mechanism as needed, such as the value of the first or third height circumferential position of the initial suction position of the suction gun.

[0068] Furthermore, when the suction gun 110 descends a predetermined height relative to the material bucket 200, the material bucket 200 rotates again relative to the fixed seat 310 with the rotating weighing base 320. At the same time, the vibration position of the vibration cylinder 620 changes, that is, the vibration position of the vibration cylinder 620 is no longer the second height circumferential position. This allows the vibration position of the vibration cylinder to adapt to the descent position of the suction gun, thereby improving the effectiveness of the vibration action of the vibration cylinder.

[0069] Furthermore, a fixing plate protrudes from the outer wall of the cylinder frame body 614, and the fixing plate is equipped with a displacement sensor. The displacement sensor is used to sense the amount of telescopic displacement of the support frame 616 relative to the cylinder frame body 614. The control mechanism obtains the amount of telescopic displacement within a predetermined time so that the control mechanism can control the displacement of the lifting drive assembly 510 according to the amount of telescopic displacement.

[0070] Furthermore, the weighing platform 300 also includes a clamping assembly, which is mounted on the fixed base 310 and is used to clamp the material bucket 200 on the outer peripheral wall so that the material bucket is reliably fixed on the fixed base.

[0071] Furthermore, the clamping assembly includes multiple clamping members and multiple elastic members, with each clamping member and elastic member corresponding to the other. The fixed base has multiple elastic grooves, and each clamping member is slidably connected to the corresponding elastic groove. Each clamping member is connected to the corresponding elastic groove through a corresponding elastic member, so that the clamping assembly is elastically slidably connected to the fixed base to adapt to the clamping needs of material buckets 200 of different diameters.

[0072] Compared with the prior art, this disclosure has at least the following advantages:

[0073] 1. The aforementioned extraction device 10 and control mechanism 700 are electrically connected to the control terminals of the negative pressure component, the lifting drive component 510, the translation drive component 520, the rotation drive component 330, and the vibration mechanism 600, respectively. When it is necessary to extract or deliver material from the material bin 200 on the rotating weighing seat 320, the control mechanism 700 first controls the lifting drive component 510 and the translation drive component 520 to operate. Since the translation drive component 520 is fixed to the power output terminal of the lifting drive component 510, there is an angle between the power output direction of the lifting drive component 510 and the power output direction of the translation drive component 520. The suction gun 110 is connected to the power output terminal of the translation drive component 520 to drive the suction gun 110 from the material bin 200. The material gun 110 moves from the external position to the suction position inside the material hopper 200. Then, the control mechanism 700 controls the negative pressure component to work, and simultaneously controls the rotary drive component 330 to work. In this way, the negative pressure component sucks up the material as the material hopper 200 rotates with the rotary weighing base 320. Even if the current height position of the material hopper 200 rotates one revolution relative to the suction gun 110, the suction gun 110 can effectively suck up the material at the current height position of the material hopper 200. Then, the control mechanism 700 controls the lifting drive component 510 to move again, so that the suction gun 110 descends to the predetermined height. At the same time, the control mechanism 700 controls the vibration mechanism 600 to vibrate against the outer wall of the material hopper 200, thereby sucking up the material at the next height position. Then, the above suction operation is repeated to realize the automatic suction of powder.

[0074] 2. When the suction gun 110 descends to the predetermined height to suction material, the vibration mechanism 600 vibrates against the outer wall of the material barrel 200, which avoids the situation where powder remains on the inner wall of the material barrel 200 or accumulates in the middle and cannot be sucked up temporarily, thus improving the material extraction efficiency and achieving fast and thorough material suction.

[0075] 3. Through the combined action of the lifting drive component 510 and the translation drive component 520, the suction gun 110 is moved in the vertical plane. At the same time, the rotation drive component 330 drives the rotating weighing seat 320 to rotate relative to the fixed seat 310, which in turn drives the material bucket 200 to rotate relative to the fixed seat 310. In addition, the vibration mechanism 600 vibrates the outer wall of the material bucket 200. No manual intervention is required in the middle, which greatly reduces the labor intensity.

[0076] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
