[0003] At present, the length of the powder processing system from mixing to filling on the market is too large, which on the one hand leads to an increase in equipment investment cost, and on the other hand easily causes problems such as powder scattering and leakage, resulting in waste of powder. SUMMARY

[0004] The present application provides a powder processing system and a processing method thereof, which is used to reduce the production cost of equipment and reduce the risk of powder scattering and leakage.

[0005] In order to achieve the above-mentioned purpose, the main technical scheme adopted by the present application comprises:

[0006] In a first aspect, the present application provides a powder processing system for mixing and filling powder, comprising a powder mixing device and a filling device. The powder mixing device comprises a powder screening device, a mixing device and a vibrating device. The powder screening device is installed on the mixing device and is in communication with the mixing device, so that the powder in the powder screening device is transported into the mixing device. The vibrating device is installed on the mixing device and vibrates the powder screening device and the mixing device simultaneously. The filling device comprises a rotating device and a filling device. The filling device is connected to the mixing device to transport the powder in the mixing device to the filling device. The filling device is installed above the rotating device. The rotating device comprises a bag clamping mechanism for clamping a packaging bag and a rotating table for driving the packaging bag to move. A plurality of bag clamping mechanisms are installed on the rotating table. The filling device is located above the bag clamping mechanism to fill the powder into the packaging bag clamped by the bag clamping mechanism.

[0007] Further, the powder screening device is installed above the mixing device along the height direction of the powder mixing device, and has a lifting degree of freedom relative to the mixing device to maintain the height difference between the opening of the powder screening device facing the mixing device and the powder in the mixing device.

[0008] Further, the powder screening device comprises a powder screening hopper, a powder screening assembly and a powder screening lifting member. The powder screening hopper is installed above the mixing device by the powder screening lifting member and at least partially extends into the mixing device. The powder screening assembly is installed on the top of the powder screening hopper, and the powder screening assembly is formed with a powder screening hole for screening the size of the powder particles.

[0009] Further, the mixing device comprises a mixing bin, a mixing stirring assembly and a mixing discharge assembly. The mixing bin is installed on the vibrating device, so that the screening device is installed on the vibrating device through the mixing bin. The mixing stirring assembly is installed on the mixing bin and at least partially extends into the mixing bin. The mixing discharge assembly is installed on the mixing bin and controls the opening and closing of the mixing bin and the filling device.

[0010] Further, the vibrating device comprises a vibrating base, a vibrating assembly and a mounting seat. The mounting seat is installed on the vibrating base and has a movement degree of freedom relative to the vibrating base. The vibrating assembly is installed on the mounting seat and drives the mounting seat to reciprocally move relative to the vibrating base.

[0011] Further, the rotating device comprises a bag clamping mechanism for clamping the packaging bag and a rotating table for driving the packaging bag to move. A plurality of bag clamping mechanisms are installed on the rotating table and at least partially extend out of the rotating table, so that the packaging bag clamped on the bag clamping mechanism is tangent to the outer edge of the rotating table and has a gap between the outer edge of the rotating table. The rotating table has a rotation degree of freedom with its axis as the rotation center.

[0012] Further, the filling device comprises a filling guide mechanism and a filling conveying mechanism. The filling guide mechanism is installed on the rotating table and has a rotation degree of freedom relative to the rotating table. The filling conveying mechanism is used for filling the packaging bag clamped on the bag clamping mechanism.

[0013] Further, the filling device further comprises a bag supporting device located upstream of the filling device. The bag supporting device comprises a suction head having a movement degree of freedom along the radial direction of the rotating table for supporting the packaging bag. The filling guide mechanism comprises a guiding state of being inserted into the packaging bag and an idle state of being located outside the packaging bag. When the filling guide mechanism is switched from the idle state to the guiding state, the filling guide mechanism is at least partially inserted into the packaging bag supported by the bag supporting device. The rotating table and the filling guide mechanism rotate simultaneously, so that the supported packaging bag and the filling guide mechanism move to below the filling conveying mechanism.

[0014] Further, the filling guide mechanism comprises a swing arm, a guide arm and a guide driving member.

[0021] At the bag-opening station, the opening of the packaging bag is opened;

[0022] Step S3.2: The expanded packaging bag is conveyed to the filling station. During the process of the expanded packaging bag moving from the expansion station to the filling station, the filling guide mechanism is inserted into the opening of the packaging bag to keep the packaging bag in an expanded state.

[0023] In step S3.3, the discharge port of the filling conveyor descends and is then guided by the filling guide machine to be inserted into the opening of the packaging bag, and quantitative filling is performed on the packaging bag. After filling is completed, the discharge port of the filling conveyor and the filling guide machine rise and leave the opening of the packaging bag.

[0024] Step S3.4: The packaging bag is transported to the sealing station. At the sealing station, the opening of the packaging bag is first closed and then sealed.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] like Figure 1 As shown, in one implementation, this application provides a powder processing system, including a powder mixing device and a filling device. The powder mixing device is used to sieve and mix the powder. The filling device is connected to the powder mixing device. The powder processed by the powder mixing device is transported to the filling device, and the mixed powder is filled into packaging bags by the filling device.

[0053] The powder mixing equipment includes a sieving device 9, a mixing device 10, and a vibration device 11. The sieving device 9 is installed on the mixing device 10 and is connected to the mixing device 10 so that the powder is conveyed into the mixing device 10 after being sieved by the sieving device 9. The vibration device 11 is installed on the mixing device 10 and vibrates the sieving device 9 and the mixing device 10 simultaneously to improve the sieving efficiency of the sieving device 9 and facilitate the conveying of the powder in the sieving device 9 to the mixing device 10 and the conveying of the powder in the mixing device 10 to the filling equipment.

[0054] By simultaneously vibrating the powder screening device 9 and the mixing device 10 using the vibration device 11, the working efficiency of the powder mixing equipment can be improved, and the production line length of the powder processing system can be shortened, reducing the risk of powder scattering and leakage.

[0055] The filling equipment includes a rotating device 1 and a filling device 4. The rotating device 1 is used to clamp the packaging bag 6 and transport the packaging bag 6 to the bottom of the filling device 4. The filling device 4 is used to fill the powder into the packaging bag on the rotating device 1. The filling device 4 is connected to the mixing device 10 to transport the powder from the mixing device 10 to the filling device 4. The filling device 4 is installed above the rotating device 1 so that the filling device 4 can fill the powder into the packaging bag on the rotating device 1.

[0056] It should be noted that the filling device 4 and the mixing device 10 are conveyed by a conveying device, which can be a conveyor belt or a screw conveyor. This application does not involve any improvement to the conveying device.

[0057] The rotating device 1 includes a bag clamping mechanism 101 for clamping the packaging bag and a rotating table 102 for driving the packaging bag to move. Multiple bag clamping mechanisms 101 are installed on the rotating table 102. The filling device 4 is located above one of the bag clamping mechanisms 101 to fill the packaging bag clamped by the bag clamping mechanism 101 with powder.

[0058] like Figure 2 and Figure 3 As shown, in one implementation, the powder sieving device 9 is installed above the mixing device 10. Along the height direction of the powder mixing device, the powder sieving device 9 has the freedom to rise and fall relative to the mixing device 10, so as to maintain the height difference between the opening of the powder sieving device 9 facing the mixing device 10 and the powder inside the mixing device 10. That is, the powder sieving device 9 can rise and fall relative to the mixing device 10, and the height of the powder sieving device 9 rises and falls with the height of the powder inside the mixing device 10, so that the distance between the opening of the powder sieving device 9 facing the mixing device 10 and the powder inside the mixing device 10 is kept within a small and constant range, thereby reducing the risk of powder dispersion and leakage.

[0059] As one implementation, the powder sieving device 9 includes a powder sieving hopper 901, a powder sieving assembly 902, and a powder sieving lifting component 903. The powder sieving hopper 901 is installed above the mixing device 10 via the powder sieving lifting component 903, so that the powder sieving hopper 901 can be raised and lowered relative to the mixing device 10. The powder sieving hopper 901 extends at least partially into the mixing device 10, so as to reduce the distance between the powder sieving hopper 901 and the powder in the mixing device 10, thereby reducing the risk of powder dispersion and leakage.

[0060] Specifically, a flange ring is formed on the outer circumference of the powder sieving hopper 901, and a flange ring is also formed on the outer wall of the mixing device 10. The powder sieving lifting component 903 is connected to the flange ring of the powder sieving hopper 901 and the flange ring of the mixing device 10 respectively, thereby driving the powder sieving device 9 to rise and fall relative to the mixing device 10.

[0061] The powder sieving lifting component 903 is a cylinder component, and a distance sensor is installed on the powder sieving hopper 901. The distance sensor is set towards the powder in the mixing device 10. The distance sensor detects the distance between the powder sieving hopper 901 and the powder in the mixing device 10. By controlling the operation of the powder sieving lifting component 903, the distance between the powder sieving hopper 901 and the powder in the mixing device 10 is kept within a certain range, thereby reducing the risk of powder scattering and leakage.

[0062] The powder sieving component 902 is installed on the top of the powder sieving hopper 901. The powder sieving component 902 has sieving holes for screening the size of powder particles. The powder is sieving through the powder sieving component 902 to prevent large powder particles from entering the powder sieving hopper 901 and improve the uniformity of powder mixing.

[0063] Specifically, the powder sieving assembly 902 includes a powder sieving plate 9021, a scraper 9022, a powder sieving motor 9023, a powder sieving stirring rod 9024, and a powder sieving agitator 9025. The powder sieving plate 9021 and the powder sieving motor 9023 are respectively installed on the powder sieving hopper 901. Multiple powder sieving holes are formed on the powder sieving plate 9021. The scraper 9022, the powder sieving stirring rod 9024, and the powder sieving agitator 9025 are respectively installed on the powder sieving motor 9023. The scraper 9022 is used to scrape the powder on the powder sieving plate 9021 to improve the powder sieving efficiency of the powder sieving plate 9021. At the same time, the scraper 9022 can crush large powder clumps during the scraping process, reducing the particle size of the powder so that the powder can pass through the powder sieving plate 902. The powder sieving stirring rod 9024 and the powder sieving agitator 9025 are both used to disperse the powder, so that the powder can enter the mixing device 10.

[0064] In one implementation, the mixing device 10 includes a mixing chamber 1001, a mixing and stirring assembly 1002, and a mixing and discharging assembly 1003. The powder sieving hopper 901 extends at least partially into the mixing chamber 1001. The mixing chamber 1001 is mounted on the vibration device 11, so that the powder sieving device 9 is mounted on the vibration device 11 through the mixing chamber 1001.

[0065] The mixing and stirring assembly 1002 is installed in the mixing chamber 1001, and the mixing and stirring assembly 1002 extends at least partially into the mixing chamber 1001 so as to stir the powder in the mixing chamber 1001 by the mixing and stirring assembly 1002.

[0066] Specifically, the mixing assembly 1002 includes a mixing motor 10021 and a mixing agitator 10022. The mixing motor 10021 is installed outside the mixing chamber 1001, and the motor shaft of the mixing motor 10021 extends into the mixing chamber 1001. The mixing agitator 10022 is installed on the motor shaft of the mixing motor 10021, and the mixing agitator 10022 stirs and mixes the powder in the mixing chamber 1001.

[0067] The mixing discharge assembly 1003 is installed in the mixing chamber 1001, and the mixing discharge assembly 1003 controls the connection and disconnection between the mixing chamber 1001 and the filling device 4.

[0068] Specifically, the mixing and discharging assembly 1003 includes a discharging channel 10031, a control board 10032, and a discharging cylinder 10033. The discharging channel 10031 is connected to and communicates with the mixing chamber 1001. The control board 10032 is oscillatingly installed at the outlet of the discharging channel 10031. The discharging cylinder 10033 is installed outside the mixing chamber 1001 and connected to the control board 10032. The discharging cylinder 10033 drives the control board 10032 to oscillate, thereby switching the discharging channel 10031 between the powder discharging and closed states.

[0069] As one implementation, the vibration device 11 includes a vibration base 1101, a vibration component 1102, and a mounting base 1103. The mounting base 1103 is mounted on the vibration base 1101 via a guide rod 1104, and the mounting base 1103 has a degree of freedom of movement relative to the vibration base 1101.

[0070] The mixing chamber 1001 is fixed on the mounting base 1103. The reciprocating shaking of the mounting base 1103 drives the mixing chamber 1001 and the powder screening device 9 to shake, thereby improving the powder screening and powder discharge efficiency.

[0071] Vibration component 1102 is mounted on mounting base 1103 and drives mounting base 1103 to reciprocate relative to vibration base 1101.

[0072] Specifically, the vibration assembly 1102 includes a vibration motor 11021 and an eccentric wheel 11022. The vibration motor is mounted on the vibration base 1101, and the eccentric wheel 11022 is mounted on the motor shaft of the vibration motor 11021. The rotation of the eccentric wheel 11022 generates an eccentric force, which drives the mounting base 1103 to move back and forth along the guide rod 1104, thereby realizing the vibration of the powder screening device 9 and the mixing device 10.

[0073] like Figure 1 As shown, the filling equipment also includes a bag feeding device 2, a bag supporting device 3, and a bag sealing device 5. The rotating device 1 is used to clamp the packaging bag 6 and to transport the packaging bag 6 to different workstations. The bag feeding device 2, the bag supporting device 3, the filling device 4, and the bag sealing device 5 are sequentially connected to one side of the rotating device 1. The bag feeding device 2 is used to transport the packaging bag 6 into the rotating device 1. The rotating device 1 rotates, causing the packaging bag 6 to move under the bag supporting device 3. The bag supporting device 3 is used to open the packaging bag 6. After the bag supporting device 3 works, the rotating device 1 rotates, causing the packaging bag 6 to move under the filling device 4. During the process of the packaging bag 6 moving from under the bag supporting device 3 to under the filling device 4, the filling guide mechanism 401 of the filling device 4 maintains the size of the opening of the packaging bag 6. The filling device 4 is used to fill the powder into the packaging bag 6. After the filling device 4 works, the rotating device 1 rotates, causing the packaging bag 6 to move under the bag sealing device 5. The bag sealing device 5 is used to seal the opening of the packaging bag 6.

[0074] The bag clamping mechanism 101 extends at least partially outside the rotary table 102, such that the packaging bag 6 clamped on the bag clamping mechanism 101 is tangent to the outer edge of the rotary table 102, and there is a gap between the packaging bag 6 and the outer edge of the rotary table 102, so as to facilitate the bag supporting device 3 and the bag sealing device 5 to perform bag supporting and bag sealing operations on the packaging bag 6.

[0075] The rotary table 102 has rotational freedom with its axis as the center of rotation. The rotation of the rotary table 102 drives the packaging bag 6 on the bag clamping mechanism 101 to pass through the bag supporting device 3, the filling device 4 and the sealing device 5 in sequence.

[0076] The number of bag clamping mechanisms 101 is at least 4, ensuring that the bag feeding device 2, bag supporting device 3, filling device 4 and bag sealing device 5 can simultaneously operate on the packaging bags 6 of the bag clamping mechanisms 101 at different workstations, thereby improving the working efficiency of the powder filling equipment.

[0077] The bag-opening device 3 includes at least two suction heads 301. Along the diameter direction of the vertical rotating table 102, both suction heads 301 have a degree of freedom of movement that can move radially along the rotating table 102. The two suction heads 301 are located on the outside of the packaging bag 6, and the two suction heads 301 move in opposite directions, so as to open the packaging bag by moving the suction heads 301.

[0078] The filling device 4 includes a filling guide mechanism 401 and a filling conveying mechanism 402. The filling guide mechanism 401 is mounted on the rotary table 102 and has a rotational degree of freedom to rotate relative to the rotary table 102. The filling conveying mechanism 402 is located above the bag clamping mechanism 101.

[0079] The filling guide mechanism 401 includes a guiding state that is inserted into the packaging bag 6 and an empty state that is located outside the packaging bag.

[0080] When the filling guide mechanism 401 is in an idle state, the filling guide mechanism 401 is located above the bag support device 3.

[0081] When the filling guide mechanism 401 switches from the idle state to the guiding state, the filling guide mechanism 401 is at least partially inserted into the packaging bag opened by the bag support device 3. The rotary table 102 and the filling guide mechanism rotate simultaneously, so that the opened packaging bag 6 and the filling guide mechanism 401 move to the bottom of the filling conveying mechanism 402.

[0082] When the filling guide mechanism 401 is in the guiding state, the filling guide mechanism 401 is located below the filling conveying mechanism 402, and the filling conveying mechanism 402 is guided and inserted into the packaging bag 6 through the filling guide mechanism 401.

[0083] like Figure 4As shown, in one implementation, the bag feeding device 2 includes a bag feeding column 201, a drive rod 202, a bag feeding arm 203, a swing limiting rod 204, and a bag feeding gripper 205. The drive rod 202 and the swing limiting rod 204 are rotatably mounted on the bag feeding column 201. The middle part of the bag feeding arm 203 is connected to the end of the drive rod 202 opposite to its swing center. One end of the bag feeding arm 203 is connected to the end of the swing limiting rod 204 opposite to its swing center. The bag feeding gripper 205 is mounted on the other end of the bag feeding arm 203.

[0084] The bag feeding device 2 also includes a conveyor belt 206 for conveying the packaging bag 6 toward the bag feeding arm 203, and a bag feeding column 201 located between the conveyor belt 206 and the rotating device 1.

[0085] A rotary motor is installed inside the bag-feeding column 201. The rotary motor drives the drive rod 202 to swing, which in turn drives the middle part of the bag-feeding arm 203 to move. The swing limit rod 204 restricts the movement of the end of the bag-feeding arm 203. Through the cooperation of the drive rod 202 and the swing limit rod 204, the bag-feeding arm 203 can swing between the bag-grabbing position and the bag-releasing position.

[0086] When the bag-feeding arm 203 is in the bag-grabbing position, the bag-feeding arm 203 is perpendicular to the conveying plane of the conveyor belt 206 so that the bag-feeding claw 205 can clamp the horizontal packaging bag 6 on the conveyor belt 206.

[0087] When the bag feeding arm 203 is in the bag feeding position, the bag feeding arm 203 is perpendicular to the bag clamping mechanism 101 so that the bag clamping mechanism 101 can clamp the packaging bag 6 on the bag feeding claw 205.

[0088] like Figure 5 and Figure 6 As shown, as one implementation method, the bag-supporting device 3 also includes a bag-supporting column 302, a bag-supporting pneumatic finger 303, and a bag-supporting connecting rod 304. The bag-supporting column 302 is located on one side of the rotating device 1. The bag-supporting pneumatic finger 303 is installed on the bag-supporting column 302. The two bag-supporting connecting rods 304 are respectively connected to the bag-supporting pneumatic finger 303. The distance between adjacent bag-supporting connecting rods 304 is changed by the bag-supporting pneumatic finger 303. The suction head 301 is fixed on the inner side of the bag-supporting connecting rod 304.

[0089] The bag-supporting column 302 extends at least partially into the bag-clamping mechanism 101, and the line connecting the ends of the bag-supporting column 302 extending into the bag-clamping mechanism 101 is parallel to the radial direction of the rotating device 1, so that the movement direction of the bag-supporting pneumatic finger 303 is parallel to the radial direction of the rotating device 1, thereby facilitating the suction head 301 to open the packaging bag 6 located between the suction heads 301.

[0090] Specifically, the rotating device 1 rotates, causing the packaging bag 6 held on the bag clamping mechanism 101 to move between adjacent suction heads 301. The pneumatic fingers 303 operate, causing the suction heads 301 to move closer together until the two suction heads 301 abut against the two end faces of the packaging bag 6 respectively. At this time, the suction heads 301 suck air, causing the packaging bag 6 to adhere to the suction heads 301. The pneumatic fingers 303 operate further, causing the suction heads 301 to separate, thus opening the packaging bag 6. The suction heads 301 separate from the packaging bag 6. The pneumatic fingers 303 operate further, creating a certain gap between the suction heads 301 and the packaging bag 6, so that the rotating device 1 can transport the opened packaging bag 6 to the filling device 4.

[0091] It should be noted that the suction head 301 is connected to an external air source, and the external air source is used to suck and blow air onto the suction head 301 so as to adsorb the packaging bag 6 onto the suction head 301 or separate the packaging bag 6 from the suction head 301.

[0092] like Figure 5 and Figure 7 As shown, in one implementation, the filling guide mechanism 401 includes a swing arm 4011, a guide arm 4012, a guide pneumatic finger 4015, and a guide lifting cylinder 4014. The guide arm 4012 is used to guide the filling conveying mechanism 402. The guide pneumatic finger 4015 is used to drive the two guide arms 4012 to move closer or apart. The swing arm 4011 is used to drive the guide arm 4012 to move between the bag supporting device 3 and the filling conveying mechanism 402. The guide lifting cylinder 4014 is used to drive the guide arm 4012 to rise and fall so that the guide arm 4012 can extend into the packaging bag 6.

[0093] The guide lifting cylinder 4014 is installed at the swing center of the swing arm 4011, and the swing arm 4011 is installed on the rotary table 102 through the guide lifting cylinder 4014. The swing arm 4011 has a rotational degree of freedom to rotate relative to the rotary table 102, so that the end of the swing arm 4011 away from its swing center swings back and forth between the bag supporting device 3 and the filling conveying mechanism 402.

[0094] The guide pneumatic finger 4015 is installed at the end of the swing arm 4011 away from its swing center, and two guide arms 4012 are respectively installed on the guide pneumatic finger 4015, so that the guide arms 4012 are installed at the end of the swing arm 4011 facing the bag clamping mechanism 101, and the guide pneumatic finger 4015 drives the two guide arms 4012 to move closer to each other or separate.

[0095] Along the stepping direction of the rotary table 102, the guide arm 4012 includes an extension 40121 for guiding the filling and conveying mechanism 402. The extension 40121 prevents the swing arm 4011 from interfering with the filling and conveying mechanism 402. At the same time, the extension 40121 can guide the filling and conveying mechanism 402 into the open packaging bag 6.

[0096] As one implementation, the filling guide mechanism 401 also includes a guide drive 4013, with the guide arm 4012 mounted on the guide drive 4013, which drives the swing arm 4011 to move circumferentially along the rotary table 102.

[0097] like Figure 5 and Figure 8 As shown, in one implementation, the filling and conveying mechanism 402 includes a filling component 4021, which is located above the bag clamping mechanism 101 and has a degree of freedom of movement to move up and down relative to the filling guide mechanism 401. During the descent of the filling component 4021, the filling guide mechanism 401 guides the filling component 4021 to be inserted into the packaging bag 6 held by the bag clamping mechanism 101.

[0098] As one implementation, the filling assembly 4021 includes a filling funnel 40211 and a lifting drive 40212. The filling funnel 40211 is installed on the lifting drive 40212. The lifting drive 40212 drives the filling funnel 40211 to rise and fall relative to the filling guide mechanism 401, thereby inserting the filling funnel 40211 at least partially into the opened packaging bag 6 to prevent the powder from scattering or leaking during filling.

[0099] During filling, the lifting drive 40212 drives the filling funnel 40211 to move downward, so that the filling funnel 40211 is at least partially inserted into the opened packaging bag 6.

[0100] It should be noted that the lifting drive component 40212 is a cylinder.

[0101] As one implementation, the filling and conveying mechanism 402 also includes a hopper 4022 and a quantitative conveying component 4023. The hopper 4022 is used to store powder, and the quantitative conveying component 4023 is used to quantitatively convey the powder to the filling component 4021 to ensure that the filling amount is consistent each time. The hopper 4022 is connected to the filling component 4021 through the quantitative conveying component 4023.

[0102] It should be noted that the silo 4022 is equipped with components such as a conveying pump to transport the powder to the metering conveying component 4023, ensuring that the metering conveying component 4023 can stably output the powder in a metered manner.

[0103] The metering conveying component 4023 extends at least partially into the filling component 4021. The filling component 4021 has a degree of freedom of movement relative to the metering conveying component 4023, that is, the filling funnel 40211 can be raised and lowered relative to the metering conveying component 4023, so that the filling funnel 40211 can be inserted into the opened packaging bag 6.

[0104] As one implementation, the quantitative conveying component 4023 includes a conveying hopper 40234, a spiral column 40232, and a buffer hopper 40233. The conveying hopper 40234 is connected to the silo 4022, and the powder in the silo 4022 is conveyed to the conveying hopper 40234. A conveying channel 40231 is formed in the conveying hopper 40234. The spiral column 40232 is installed in the conveying channel 40231 and has a rotational degree of freedom to rotate relative to the conveying channel 40231. The powder is quantitatively output from the conveying hopper 40234 through the spiral column 40232. The buffer hopper 40233 is connected to the conveying hopper 40234 through a pipe fitting, and the buffer hopper 40233 is at least partially inserted into the filling funnel 40211.

[0105] Spiral blades are formed on the circumferential sidewall of the spiral column 40232. The rotation of the spiral column 40232 causes the powder to be conveyed in the conveying channel 40231. The amount of powder flowing through the conveying channel 40231 is controlled by controlling the rotation angle of the spiral column 40232.

[0106] In one implementation, a stirring paddle is installed inside the hopper 4022 to stir the powder inside the hopper 4022, thereby preventing the powder from clumping.

[0107] like Figure 9 As shown, as one implementation method, the sealing device 5 includes two sealing mechanisms, which are arranged along the rotation direction of the rotating device 1, so as to perform two sealing operations on the same packaging bag 6 through the two sealing mechanisms, thereby improving the sealing performance of the packaging bag 6.

[0108] Specifically, the sealing mechanism includes a first clamping block 501, a second clamping block 502, a first guide rod 503, a second guide rod 504, a gear 505, a sealing cylinder 506, and a sealing base 507. The first guide rod 503 and the second guide rod 504 are slidably mounted on the sealing base 507 via a slider. The first clamping block 501 is mounted on the end of the first guide rod 503, and the second clamping block 502 is mounted on the end of the second guide rod 504. Racks are connected to the opposite surfaces of the first guide rod 503 and the second guide rod 504, and the gear 505 meshes with the racks on the first guide rod 503 and the second guide rod 504, thereby realizing the movement of the first clamping block 501 and the second clamping block 502 towards or away from each other.

[0109] Heating wires are installed on the first clamping block 501 and the second clamping block 502 respectively. Under the action of the heating wires, the temperature of the first clamping block 501 and the second clamping block 502 rises, so that when the first clamping block 501 and the second clamping block 502 clamp the packaging bag 6, the opening of the packaging bag 6 is heat-sealed.

[0110] Alternatively, an ultrasonic generator may be installed on the first clamping block 501 and the second clamping block 502. When the first clamping block 501 and the second clamping block 502 clamp the packaging bag 6, the opening of the packaging bag 6 may be sealed by ultrasonic waves.

[0111] As one implementation method, the sealing cylinder 506 and the bag clamping mechanism 101 work simultaneously. When the sealing cylinder 506 drives the first clamping block 501 and the second clamping block 502 to move closer to each other, the bag clamping mechanism 101 works, causing the two ends of the packaging bag 6 to move away from each other, reducing the opening of the packaging bag 6 until the opening of the packaging bag 6 is in a straight line, so that the sealing device 5 can seal the packaging bag 6.

[0112] like Figure 1 As shown, as one implementation method, the powder filling equipment also includes an output conveyor belt 7, which is installed below the end sealing mechanism. After the end sealing mechanism is working, the packaging bag 6 separates from the bag clamping mechanism 101 and falls to the output conveyor belt 7, through which the packaged powder is output.

[0113] like Figure 1 As shown, as one implementation method, the powder filling equipment also includes a weighing device 8, which is located in the middle or at the end of the output conveyor belt 7, and is used to weigh the packaged powder so as to facilitate screening of the packaged powder according to its weight.

[0114] As one implementation method, a rotary motor is installed at the bottom of the rotary table 102, which drives the rotary table 102 to rotate.

[0115] like Figure 10 and Figure 11 As shown, in one implementation, the bag clamping mechanism 101 includes a gathering component 1011, a reset drive component 1012, two clamping components 1013, and a bag clamping base 1014. The clamping components 1013 and the gathering component 1011 are slidably mounted on the bag clamping base 1014, and the moving direction of the clamping component 1013 is perpendicular to the moving direction of the gathering component 1011. The two clamping components 1013 are respectively connected to the gathering component 1011, and the reset drive component 1012 is connected to the gathering component 1011.

[0116] Under the action of the reset drive 1012, the retraction assembly 1011 includes a directional retraction state and a reset state.

[0117] When the gathering component 1011 is in the gathered state, the two clamping components 1013 are connected to the gathering component 1011 respectively. The clamping components 1013 have the freedom of movement to move closer to each other. That is, the two clamping components 1013 are clamped at both ends of the packaging bag 6. The bag supporting device 3 works, which reduces the distance between the two ends of the packaging bag 6, thereby making the clamping components 1013 move closer to each other.

[0118] When the retracting component 1011 is in the reset state, the two clamping components 1013 are separated from the retracting component 1011, so that the retracting component 1011 loses its limiting effect on the two clamping components 1013, thereby giving the two clamping components 1013 the freedom of movement to move closer to each other or separate from each other, that is, the two clamping components 1013 can move closer to each other or separate from each other.

[0119] As one implementation, the bag clamping mechanism 101 also includes a return spring 1016, which is located between adjacent clamping assemblies 1013. The return spring 1016 applies a separating force to each of the two clamping assemblies 1013.

[0120] When the closing component 1011 is in the reset state, the two clamping components 1013 separate from each other under the action of the reset spring 1016, thereby closing the opening of the packaging bag 6, which makes it easier for the sealing device 5 to seal the packaging bag 6.

[0121] As one implementation, the clamping assembly 1013 includes a slider 10131, a connecting post 10132, a clamping fixing block 10133, a clamping swing block 10134, and a clamping motor 10135. The clamping swing block 10134 is oscillatingly mounted on the clamping fixing block 10133 via a rotating shaft. The clamping motor 10135 is connected to the clamping swing block 10134, so that the clamping swing block 10134 can swing relative to the clamping fixing block 10133, thereby achieving the clamping of the packaging bag 6 on the clamping assembly 1013 or the separation of the packaging bag 6 from the clamping assembly 1013.

[0122] The slider 10131 is connected to the clamping and fixing block 10133 via the connecting post 10132. The slider 10131 is slidably mounted on the bag base 1014, and the sliding direction of the slider 10131 is parallel to the tangent of the rotation direction of the rotary table 102, so that adjacent clamping components 1013 can move closer to each other or move apart from each other.

[0123] In one implementation, the retracting component 1011 includes a limiting block 10111 and a retracting rack 10112. The limiting block 10111 is mounted on the clamping component 1013 and has a degree of freedom of movement to move toward or away from the retracting rack 10112, so that the limiting block 10111 can move in a direction perpendicular to the retracting rack 10112, thereby facilitating the movement of the limiting block 10111 relative to the retracting rack 10112.

[0124] The retracting rack 10112 has a first tooth 10112a and a second tooth 10112b, which face opposite directions.

[0125] The limiting blocks 10111 on the two clamping components 1013 extend to the first tooth 10112a and the second tooth 10112b respectively, so as to bring the two clamping components 1013 closer to each other.

[0126] During the process of opening the packaging bag 6, the first tooth 10112a and the second tooth 10112b limit the limiting block 10111, causing the two clamping components 1013 to move closer to each other.

[0127] In one implementation, the reset drive 1012 is a cylinder, which is connected to the retracting rack 10112 and drives the retracting rack 10112 to move radially along the rotating device 1.

[0128] When the gathering component 1011 is in the reset state, the gathering rack 10112 separates from the limiting block 10111. Under the action of the reset spring 1016, the two clamping components 1013 separate from each other, causing the opening of the packaging bag 6 to close.

[0129] As one implementation, a mounting post 1015 is installed on the bag clamping base 1014, and the bag clamping base 1014 is installed on the lower end face of the rotary table 102 via the mounting post 1015.

[0130] This application also provides a powder processing method, including the following steps:

[0131] Step S1: Vibrate and sieve the powder.

[0132] Specifically, the reciprocating vibration frequency of the vibrating device is 300-500 times / minute, the sieve hole size of the sieve plate 9021 is 2-3mm, and the sieve plate 9021 can be replaced as needed to meet the sieve requirements of different powders.

[0133] Step S2: Mix and stir the sifted powder.

[0134] Specifically, the sifted powder falls into the mixing device 10 through the bottom opening of the sifting hopper 901. The mixing device 10 further mixes the powder, and the agitator 10022 rotates at 100-120 rpm. As the powder falls into the mixing device 10, its height gradually increases. During this process, the sifting hopper 901 moves upward under the action of the sifting lifting component 903, maintaining the distance between the sifting hopper 901 and the top of the powder.

[0135] Step S3: The mixed powder is quantitatively filled. During the quantitative filling process, the packaging bag is moved sequentially to the bag opening station, the filling station, and the sealing station. The bag opening station is used to open the opening of the packaging bag, the filling station is used to fill the packaging bag with powder, and the sealing station is used to close the opening of the packaging bag.

[0136] Step S3 includes the following steps:

[0137] Step S3.1: The packaging bag is clamped to the bag clamping mechanism 101 of the rotating device 1 by the bag feeding device 2, and the packaging bag is moved to the bag opening station. At the bag opening station, the opening of the packaging bag is opened by the bag opening device 3.

[0138] Step S3.2: The expanded packaging bag is conveyed to the filling station. During the process of the expanded packaging bag moving from the expansion station to the filling station, the filling guide mechanism 401 is inserted into the opening of the packaging bag to keep the packaging bag in an expanded state.

[0139] In step S3.3, the discharge port of the filling conveying mechanism 402 descends and is then guided into the opening of the packaging bag by the filling guide 401, and quantitative filling is performed on the packaging bag. After filling is completed, the discharge port of the filling conveying mechanism 402 and the filling guide mechanism 401 rise away from the opening of the packaging bag.

[0140] Step S3.4: The packaging bag is transported to the sealing station. At the sealing station, the opening of the packaging bag is first closed by the bag clamping mechanism 101, and then the opening of the packaging bag is sealed by the sealing device 5.

[0141] For example, this powder processing method can be fully automated by the powder processing system in this embodiment.

Various modifications and variations can be made to this application by those skilled in the art.
