Abstract
Description
[Technical Field]
[0001] This invention belongs to the technical field of filling and sealing machines, and in particular relates to a disc-type high-efficiency fully automatic powder filling and sealing machine. [Background Technology]
[0002] Filling and sealing machines are widely used in many fields such as food and pharmaceuticals. Filling and sealing machines are divided into disc type and single-row linear type. Most of the existing disc type filling and sealing equipment is a single-head structure, which has low filling and sealing efficiency and low degree of automation. Moreover, there are many problems with filling and sealing.
[0003] Therefore, in order to improve filling efficiency, there are multi-head disc filling machines designed, such as the four-head disc filling and sealing equipment disclosed in Chinese Patent Publication No. CN213008984U, which includes a working platform, cup receiving holes, cup dropping device, feeding device, sealing device, film dispensing device, and discharge device. Multiple sets of cup receiving holes are opened on the working platform, and the cup dropping device, feeding device, sealing device, and discharge device are arranged in sequence on the working platform. A suction device is provided at the bottom of the working platform below the cup dropping device, and a film dispensing device is provided on the sealing device. Although the scheme has a four-head structure and can complete the filling action of four cups at the same time, the scheme still has the following problems: (1) The disc has the problem of wasted space. Since the disc is characterized by a small inner diameter and a large outer diameter, and the multiple sets of cup receiving holes are arranged in a straight line along the radial direction in this scheme, (1) The distance between the cup-holding holes increases sequentially from the inner circle to the outer circle in the circumferential direction. Therefore, the space of the disc is not fully utilized, resulting in a relatively small number of cup-holding holes on the disc, and the production efficiency is limited. (2) A suction device is also required below the cup dropping device to suck out the cup. The suction device includes a suction cup, a hydraulic telescopic rod, an air guide pipe and a negative pressure pump. If the cup spacing is too small or the cups are too tight, there will be a phenomenon of not being able to suck them out. (3) The feeding device is equipped with four feeding cylinders. The liquid storage tank and the feeding cylinders are connected by a conduit. If the feeding cylinders are directly fed downwards, powder blockage will occur, resulting in inaccurate feeding. (4) After feeding, the sealing operation is carried out directly. If there is powder left at the mouth of the cup when feeding, the sealing will not be tight, and there will be air leakage, which will reduce the filling and sealing yield and thus increase the production cost.
[0004] Therefore, it is necessary to provide a disc-type high-efficiency fully automatic powder filling and sealing machine to solve the above-mentioned technical problems. [Summary of the Invention]

[0023] Compared with the prior art, the beneficial effects of the disc-type high-efficiency fully automatic powder filling and sealing machine of the present invention are as follows: (1) The disc body is provided with at least two rings of receiving grooves for supporting cups. All the receiving grooves can be divided into several groups of accommodating units with the same structure at equal angles along the circumference of the disc body. The receiving grooves provided on the accommodating unit are arranged in the smallest periodic arrangement unit. Moreover, the total number of receiving grooves in each accommodating unit is at least three and the number of receiving grooves in the outermost ring is at least two. Since the disc body has the characteristic of having a small inner circumference and a large outer circumference, the number of receiving grooves provided in the inner ring is small and the number of receiving grooves provided in the outer ring is large. The reasonable layout of the receiving grooves and the provision of as many receiving grooves as possible for placing cups can improve the space utilization rate of the disc body; Moreover, each Each accommodating unit is equipped with a corresponding processing device, and each processing device is equipped with multiple processing heads corresponding to multiple receiving slots on each accommodating unit to work simultaneously, which can improve the efficiency of filling and sealing; (2) The cup-separating module includes a rotating seat for blocking the bottom cup and a shifting support plate for separating the bottom cup from the second to last cup and supporting the second to last cup at the same time. The rotating seat and the shifting support plate are designed separately and have a simple structure, which is easy to process and has a low production cost; If the thickness of the cup remains unchanged, and only the cup of different size is changed, if only the diameter of the cup body and the diameter of the cup mouth are changed, the distance between the two rotating seats and / or the two shifting support plates of the corresponding two cup-separating modules can be adjusted to adapt to different sizes. (3) The feeding screw on the feeding device is installed inside the stirring shaft. The layout design of the stirring module and the feeding module is compact and occupies little space. Moreover, the stirring blades set on both sides of the stirring shaft can continuously stir the powder in the receiving hopper, avoiding the powder entering the feeding screw from clumping and blocking the feeding screw. (4) The pressing module is set above the mold plate, while the pushing module for pushing the cup is set below the rotating disc. The upper and lower settings can save space above the mold plate and are beneficial to the layout of processing mechanisms on other workstations. When the cup enters the pressing and suction device, each pressing module and the cup form a space for containing residual powder. Each space is gathered into the gathering channel. Inside, the residual powder flows out through the collection channel, which has a high powder absorption efficiency. Moreover, multiple powder pressing modules surround the outer periphery of the collection channel, which is compact and saves space. (5) The drive module set on the film cutting and pre-sealing mechanism is set as an eccentric linkage structure, which can convert the rotary drive into a linear drive. Compared with the linear motor drive, it can save space and reduce the space occupied by the whole device. Moreover, only one first rotary motor is set to drive the first heat sealing head, the cutter and the elastic pressing component to move up and down at the same time, which can improve the rhythm of movement and improve production efficiency. The film cutting and pre-sealing module is equipped with several elastic pressing components to press the film on the cup mouth, which can ensure the integrity of the cut when the cutter is cutting and improve the quality of film cutting and pre-sealing.(6) The gripper mechanism on the unloading device has several pairs of grippers. The two grippers in each pair are hinged to the moving bracket via connecting rods. A drive cylinder moves the moving bracket, causing the grippers to simultaneously clamp the cups. A drive motor rotates the mounting plate to complete the material handling. The structure is simple and the drive method is even simpler. The grippers extend horizontally, allowing the gripper mechanism to reach horizontally into the processing table to move upright cups to the next process. This is suitable for handling on machines with limited vertical space, making it highly adaptable. [Attached Image Description]

Detailed Implementation Methods
[0053] Please refer to Figures 1-29 This embodiment is a disc-type high-efficiency fully automatic powder filling and sealing machine, which is used to fill powder into cups 200 and seal them to obtain the filled finished product. The disc-type high-efficiency fully automatic filling and sealing machine 100 includes a rotating disc 1 that carries and transports the cups 200, and a plurality of processing devices arranged sequentially around the outer circumference of the rotating disc 1 along the conveying direction of the rotating disc 1. The processing devices include a cup dropping device 3 for dropping the cup, a feeding device 4 for adding powder into the cup 200, a powder pressing and suction device 5 for flattening the powder in the cup and sucking away residual powder at the cup mouth 201, a film cutting and pre-sealing device 6 for cutting the film and pre-sealing the cup mouth 201, a heat sealing device 7 for heat sealing the cup mouth 201, and a feeding device 8 for transporting the sealed finished product on the rotating disc 1 to the conveyor line.
[0054] The rotating disk 1 includes a disk body 11 and at least two rings of support grooves 12 arranged in a ring on the disk body 11 for supporting the cup 200. In this embodiment, the disk body 11 is made of metal.
[0055] The receiving groove 12 extends through the upper and lower surfaces of the disc body 11. The upper end of the groove wall of the receiving groove 12 is provided with an annular support protrusion 121 that supports the upper end of the cup 200. The annular support protrusion 121 extends from the groove wall of the receiving groove 12 toward the center. The upper edge of the cup 200 rests on the annular support protrusion 121 to prevent it from falling out of the receiving groove 12.
[0056] All the receiving slots 12 can be divided into several groups of identical receiving units 13 arranged at equal angles along the circumference of the disc 11. The receiving slots 12 arranged on the receiving unit 13 are the smallest periodic arrangement units and cannot be further subdivided. The number of receiving modules 131 on each receiving unit 13 is equal to the number of rings of the receiving slots 12 on the disc 11. Therefore, the receiving unit 13 includes at least two receiving modules 131 arranged radially from the center of the disc 11 outwards. Since the disc 11 is annular with a smaller inner circumference and a larger outer circumference, the number of receiving slots 12 arranged in the inner ring is small, while the number of receiving slots 12 arranged in the outer ring is large. By rationally arranging the positions of the receiving slots 12 and providing as many receiving slots 12 as possible for placing cups 200, the space utilization rate of the disc 11 can be improved.
[0057] The total number of receiving slots 12 in each receiving unit 13 is at least three, and the number of receiving slots 12 in the outermost ring is at least two. If there are two rings of receiving slots 12, the inner ring receiving module 131 has one receiving slot 12 and the outer ring has two receiving slots 12. In this case, there are three receiving slots 12 in each receiving unit 13, which is the minimum periodic arrangement unit and cannot be further divided. If there are three rings of receiving slots 12, the inner ring receiving module 131 has at least one receiving slot 12, the middle ring can have at least one receiving slot 12, and the outer ring has at least two receiving slots 12. In this case, there are at least four receiving slots 12 in each receiving unit 13. As many receiving slots 12 as possible are arranged in the same receiving unit 13. The more receiving slots 12 arranged in a receiving unit 13, the higher the utilization rate of the rotating disk 1 can be, and the higher the production efficiency can be.
[0058] In this embodiment, the number of rings of the receiving groove 12 is set to two, and the corresponding number of receiving modules 131 is set to two. The receiving module 131 includes a first receiving module 1311 and a second receiving module 1312 arranged radially from the center of the disc body 11 outward. Both the first receiving module 1311 and the second receiving module 1312 are provided with receiving grooves 12. The first receiving module 1311 is provided with one receiving groove 12, and the second receiving module 1312 is provided with two receiving grooves 12. Therefore, each receiving unit 13 has two receiving modules and a total of three receiving grooves 12. Cups 200 can be placed in the three receiving grooves 12 at the same time, and the three receiving grooves 12 are arranged in a triangular structure. Therefore, during filling and sealing, three processing heads can be set at each station to work simultaneously. Therefore, this solution can improve the filling and sealing efficiency while setting as many receiving grooves 12 as possible on the disc body 11.
[0059] In other embodiments, the number of rings of the receiving groove 12 can be set to correspond to the number of receiving modules 131, and the number of receiving grooves 12 on the multiple receiving modules 131 increases from the center of the disc 11 to the outer periphery. However, the specific number of each receiving module 131 is not limited and can be adjusted according to the actual layout. As long as the position of the receiving grooves 12 is reasonably arranged and as many receiving grooves 12 for placing cups 200 as possible are provided, the space utilization rate of the disc 11 can be improved.
[0060] The cup dropping device 3 includes a cup dropping mounting frame 31 disposed above the rotating disc 1, a cup holder 32 disposed on the cup dropping mounting frame 31 for storing vertically stacked cups 200, a cup separating module 33 disposed below the cup holder 32, a cup dropping drive mechanism 34 for driving the cup separating module 33 to rotate to realize the cup dropping action, and a cup suction module 35 disposed below the rotating disc 1 and corresponding to the cup dropping drive mechanism 34. Each cup holder 32 has two corresponding cup separating modules 33, and the two cup separating modules 33 are disposed opposite each other on the left and right sides of the cup holder 32.
[0061] The cup holder 32 includes several guide posts, which together form a vertical channel for accommodating cups 200. Cups 200 are stacked in the cup holder 32 with their openings facing upwards. The cup-dropping mounting bracket 31 includes a through hole 311 at the bottom of the cup holder 32 for dropping the cups 200, and a second clearance hole 312 for avoiding the cup-separating module 33. The second clearance hole 312 has an opening on the side facing the through hole 311, allowing the second clearance hole 312 to communicate with the through hole 311. This allows the cup-separating module 33 to enter the through hole 311 through the opening to block the cups 200 or separate them, thus achieving the cup-dropping action. A storage compartment 321 for temporarily storing cups 200 is provided on one side of the cup holder 322, and a conveying groove 3211 corresponding to the cup holder 32 is provided on the storage compartment 321.
[0062] The cup-dropping drive mechanism 34 includes several cup-dropping rotating shafts 341 rotatably mounted on a cup-dropping mounting frame 31 for mounting several cup-dividing modules 33, a cup-dropping driven wheel 342 fixed to the upper end of the cup-dropping rotating shafts 341, a cup-dropping rotating drive component 343 mounted on the cup-dropping mounting frame 31, and a cup-dropping driving wheel 344 driven by the cup-dropping rotating drive component 343. The cup-dropping driving wheel 344 and the cup-dropping driven wheel 342 are connected together by a cup-dropping transmission belt 345 to achieve rotational transmission. Several bearings are provided on the outer periphery of the cup-dropping rotating shafts 341, and the cup-dropping rotating shafts 341 are mounted on the cup-dropping mounting frame 31 through the bearings. The cup-dropping rotating shafts 341 are provided with mounting bosses 3411 for mounting the cup-dividing modules 33. A tensioning wheel 347 is rotatably disposed between two adjacent cup-dropping driven wheels 342 to control the tension of the cup-dropping transmission belt 345. The tensioning wheel 347 is rotatably disposed on a pin, and the lower end of the pin is mounted on the cup-dropping mounting bracket 31.
[0063] The cup-dividing module 33 is roughly cylindrical and is installed on the lower surface of the mounting boss 3411. The middle of the cup-dividing module 33 is provided with a first mounting hole 333 that mates with the lower end of the cup-dropping rotating shaft 341. The cup-dividing module 33 is also provided with an oblong hole 334 that is vertically opposite to the threaded hole 3412. The cup-dividing module 33 is inserted into the lower end of the cup-dropping rotating shaft 341 through the first mounting hole 333 and contacts the lower surface of the mounting boss 3411. Then, bolts or pins are inserted into the threaded hole and oblong hole 334 of the mounting boss 3411 to fix the cup-dividing module 33 on the lower surface of the mounting boss 3411, thereby realizing the installation and fixation of the cup-dividing module 33 and the cup-dropping rotating shaft 341. The cup-separating module 33 includes a rotating base 331 for blocking the bottom cup 200 and a toggle support plate 332 for separating the bottom cup 200 from the second-to-last cup 200 and supporting the second-to-last cup 200. The toggle support plate 332 is fixed to the upper end of the rotating base 331 by a cylindrical pin.
[0064] The rotating base 331 is roughly cylindrical in shape. A cup-dispensing notch 336 extending from the upper to the lower end face is provided on one side of the outer periphery of the rotating base 331. The cup-dispensing notch 336 is formed by cutting a vertical plane from the upper to the lower end face of the rotating base 331 to allow the cup 200 to fall from this point. Therefore, when the two cup-dispensing notches 336 of the corresponding two cup-separating modules 33 are opposite each other, the distance between the two cup-dispensing notches 336 is greater than the diameter of the cup opening 201. An annular groove 337 is provided on the upper outer edge of the rotating base 331 to avoid the cup opening 201. The vertical height of the annular groove 337 is similar to the vertical height of the cup opening 201. The groove 337 is on the opposite side of the cup outlet 336, which is the cup inlet 338 for the cup 200 to fall into. After the cup 200 falls, the cup opening 201 is supported on the bottom of the annular groove 337 at the cup inlet 338. Therefore, when the two cup inlets 338 of the two corresponding cup-separating modules 33 are opposite each other, the distance between the two cup inlets 338 is less than the diameter of the cup opening 201. The vertical height of the annular groove 337 is similar to the vertical height of the cup opening 201 so that only one cup 200 falls into the cup inlet 338 at a time, and the rotating seat 331 can rotate and extend into the through hole 311 at the cup inlet 338 to support the cup 200.
[0065] The actuating support plate 332 has a circular structure. The second mounting hole 3321 is offset from the center of the actuating support plate 332, so that the actuating support plate 332 is eccentrically positioned above the rotating seat 331. Therefore, one side of the actuating support plate 332 is provided with an actuating support part 3324 that extends out of the cup outlet notch 336 and into the through hole 311 to separate the bottom cup 200 from the second to last cup 200 and simultaneously support the second to last cup 200. The other opposite side of the actuating support part 3324 is located inside the annular groove 337 so that the cup 200 can fall into the cup inlet 338. By eccentrically positioning the actuating support plate 332, the cup 200 can be dropped, and the cups can be separated and supported at the same time. The outer circumferential edge of the actuating support plate 332 is provided with a guide surface 3325 that can be smoothly inserted into the two cup openings 201. The thickness of the guide surface 3325 increases from the outer edge to the inner side, so that the actuating support plate 332 can smoothly enter between the two cup openings 201. The increasing thickness can separate the bottom cup 200 from the second to last cup 200, so that the bottom cup 200 can fall smoothly.
[0066] If the thickness of the cup 200 remains unchanged, and only a different size cup 200 is replaced, only the diameter of the cup body and the diameter of the cup mouth 201 are changed. The position of the rotating seat 331 and the support plate 332 can be adjusted to adapt to different sizes without the need for a complete replacement, making it more versatile.
[0067] The cup suction module 35 includes several cup sleeves that can extend into the receiving groove 12 on the disc 2 and a cup suction drive component that drives the cup sleeves to move up and down. Each cup sleeve has a suction cup at its top.
[0068] When the cup dropping device 3 is working, the cups 200 placed in the storage compartment 321 are pushed towards the cup holder 32. The cups 200 enter the cup holder 32 and move upward along the upright of the cup holder 32, so that all the cups 200 in the storage compartment 321 enter the vertical channel in the cup holder 32, and the cups 200 are stacked in the cup holder 32 with their openings facing upwards. The cup dropping drive mechanism 34 starts to work. The cup dropping rotation drive 343 drives the cup dropping drive wheel 344 to drive the cup dropping rotation shaft 341 to rotate, so that the cup inlets 338 of the cup separating modules 33 on both sides are facing each other. At this time, the bottom cup 200 is blocked at the two cup inlets 338, and the cup opening 201 of the bottom cup 200 is supported on the bottom of the annular groove 337 at the cup inlet 338. The cup dropping rotation drive 343 drives the cup dropping drive wheel 344 to rotate. 4. The rotating shaft 341 drives the cup-dropping mechanism to rotate, causing the two cup-dispensing notches 336 of the cup-separating modules 33 on both sides to face each other. During the rotation of the cup-separating modules 33, the actuating support plate 332 is gradually inserted horizontally between the cup opening 201 of the bottom cup 200 and the cup opening 201 of the second to last cup 200. When the actuating support plate 332 is facing each other, it presses the bottom cup 200 downward while supporting the second to last cup 200. At this time, because the two cup-dispensing notches 336 are facing each other, the actuating support part 3324 is inserted to the deepest depth. After the actuating support plate 332 presses the bottom cup 200 downward, the bottom cup 200 automatically falls from the cup-dispensing notch 336. All three cups 200 fall at the same time. At the same time, the suction module 35 moves upward to suck the cups into the three receiving slots 12 on the rotating disc 1 below.
[0069] The feeding device 4 includes a storage module 41 for storing powder, a receiving hopper 42 located below the storage module 41, a conveying pipe 43 for conveying powder from the storage module 41 to the receiving hopper 42, a second support frame 44 for fixing the storage module 41 and the receiving hopper 42, a stirring module 45 for stirring the powder in the receiving hopper 42, and several feeding modules 46 for quantitatively adding powder from the receiving hopper 42 into a cup. A first pusher is also provided below the disc 1 to push the cup 200 upwards. The cup module 48; the stirring module 45 includes several stirring shafts 451 whose lower ends extend into the receiving hopper 42, and a pair of stirring blades 456 are installed opposite each other on both sides of the stirring shafts 451; the feeding module 46 includes a feeding screw 461 inserted inside the stirring shafts 451 and extending out of the upper and lower ends of the stirring shafts 451, and a feeding motor 462 fixed on the second support frame 44 and driving the feeding screw 461 to rotate; the lower end of the receiving hopper 42 is provided with several feeding nozzles 421 that correspond to the upper and lower ends of the feeding screw 461.
[0070] In this embodiment, powder needs to be added to three cups 200 at the same time, so three feeding modules 46 need to be set up. Therefore, three stirring shafts 451 and three feeding nozzles 421 are set up accordingly. The three feeding screws 461 of the three feeding modules 46 extend into the stirring shafts 451 and extend out of both ends of the stirring shafts 451 at the same time.
[0071] The lower end of the receiving hopper 42 is provided with several feeding nozzles 421 corresponding to the feeding screw 461. The lower end of the feeding screw 461 extends into the lower end of the corresponding feeding nozzle 421 to realize the feeding action. The discharge funnel is provided with a material level detector 422.
[0072] The second support frame 44 includes a second support plate 441 for mounting the storage module 41 and a third support plate 442 located below the first support plate 42 for mounting the receiving hopper 42. The second support plate 441 and the third support plate 442 are fixed together by Z-shaped support plates 443 on both sides, and the receiving hopper 42 is fixed to the lower surface of the third support plate 442.
[0073] The stirring module 45 also includes a driven stirring wheel 452 fixed to the upper end of the stirring shaft 451, a stirring motor 453 mounted on the third support plate 442, and a driving stirring wheel 454 driven by the stirring motor 453. In this embodiment, since there are three stirring shafts 451, there are three driven stirring wheels 452. The driving stirring wheel 454 and the three driven stirring wheels 452 are connected together by several meshing gears 455 to achieve meshing transmission. There are three meshing gears 455. The stirring shaft 451 has a shaft hole that passes through the upper and lower ends and allows the feeding screw 461 to pass through. The upper surface of the third support plate 442 is fixed with a bearing sleeve 457 by studs. Several bearings are provided on the outer periphery of the stirring shaft 451. The stirring shaft 451 is installed in the bearing sleeve 457 through the bearings. A first sealing ring is provided on the outer periphery of the stirring shaft 451 to achieve a seal between the stirring shaft 451 and the bearing sleeve 457. Limiting sleeves are installed between several bearings to limit their movement; the upper end of the bearing sleeve 457 is fixed to the third support plate 442, and the lower end extends into the receiving hopper 42; the first sealing ring is located on the inner side of the lower end of the bearing sleeve 457, and the first sealing ring is used to seal between the stirring shaft 451 and the bearing sleeve 457 to prevent powder from entering the bearing sleeve 457 and hindering the rotation of the stirring shaft 451, thereby affecting the stirring of the powder in the receiving hopper 42. The stirring shaft 451 is a stepped shaft, and the lower outer circumference of the stirring shaft 451 is provided with a vertical stirring blade mounting groove for mounting the stirring blade 456. The stirring drive wheel 454 and several stirring driven wheels 452 are located on the upper surface of the third support plate 442. The meshing gear 455 is rotatably mounted on the meshing gear shaft 4551, which is fixed to the third support plate 442. The feeding motor 462 is fixed to the third support plate 442. The third support plate 442 is equipped with a silencer 47 for reducing noise, thereby preventing the feeding device from generating excessive noise that may affect the workers' operations.
[0074] The feeding screw 461 is mounted inside the stirring shaft 451 via a bearing. A second sealing ring is fitted around the outer circumference of the feeding screw 461 on the stirring shaft 451. The lower end of the stirring shaft 451 has a mounting groove for mounting the bearing and the second sealing ring. The second sealing ring is used to seal between the feeding screw 461 and the stirring shaft 451, preventing powder from entering between the stirring shaft 451 and the feeding screw 461 and obstructing the rotation of the stirring shaft 451 and the feeding screw 461, thus avoiding affecting the mixing and feeding of powder.
[0075] After the cup 200 is placed in the container, it is conveyed by the rotating disc 1 to the feeding device 4. The feeding device 4 then starts working. The vacuum feeder 411 conveys the powder into the storage hopper 412. The feeding motor 413 drives the rotating conical platform 414 to drive the stirring blades 415 to stir the powder in the storage hopper 412. At the same time, the stirring blades 415 push the powder into the inlet hole 4121 and into the receiving hopper 42 below through the conveying pipe 43. The stirring motor 453 drives the stirring drive wheel 454 to rotate the stirring shaft 451, thereby driving a pair of stirring blades 456 fixed on the stirring shaft 451 to stir the powder in the receiving hopper 42. The powder is stirred so that it enters the spiral groove of the feeding screw 461 evenly. When feeding is needed, the weight of feeding can be adjusted by controlling the number of rotations of the feeding motor 462. The three feeding motors 462 drive the three feeding screws 461 to rotate simultaneously, so that the powder enters the cup 200 below through the feeding nozzle 421. At the same time, the first cup pusher module 48 pushes the cup 200 upward to catch the powder, thus completing the feeding of the three cups 200. When feeding is not needed, the feeding motors 462 stop driving the feeding screws 461 to rotate, and the powder is stored in the spiral groove of the feeding screw 461 and will not fall.
[0076] The powder pressing and suction device 5 includes a mounting base 52 disposed above the rotating disk 1, several powder pressing modules 53 disposed inside the mounting base 52, a pushing module 54 disposed below the rotating disk 1 for driving the cup 200 to move upward to contact the powder pressing modules 53 to achieve powder pressing, and a suction tube 51 mounted on the mounting base 52; the mounting base 52 includes a converging channel 521 extending upward through the upper surface and a plurality of first clearance holes 522 extending downward through the lower surface and allowing the cup 200 to enter, converging... A powder suction tube 51 is installed at the upper end of the channel 521. The first clearance hole 522 is open on the side facing the converging channel 521 and communicates with the converging channel 521. When the pushing module 54 pushes the cup 200 upward into place, the outer wall of the powder pressing module 53, the cup mouth 201, and the hole wall of the first clearance hole 522 together form a residual powder receiving space 55. A powder movement channel 56 is formed inside the mounting base 52, which enters the converging channel 521 from multiple receiving spaces 55 and then enters the powder suction tube 51 through the converging channel 521.
[0077] The mounting base 52 includes a bottom support base 523 and a mounting upper seat 524 mounted on top of the support base 523 for mounting the powder pressing module 53. A first clearance hole 522 is provided on the support base 523 and penetrates the upper and lower surfaces of the support base 523. An annular support 5221 for supporting the cup mouth 201 is provided at the lower end of the first clearance hole 522. The annular support 5221 extends from the hole wall of the first clearance hole 522 towards the center. The support base 523 is provided with a converging groove 5231 that extends upward and penetrates the upper surface. The mounting upper seat 524 is provided with a through hole 5241 that penetrates the upper and lower surfaces. The converging groove 5231 and the through hole 5241 are connected vertically to form a converging channel 521. The first clearance hole 522 is open on the side facing the converging groove 5231 and communicates with the converging groove 5231. The mounting base 524 has a second mounting hole 5242 for mounting the powder pressing module 53 at the location of the first clearance hole 522. The diameter of the first clearance hole 522 is larger than the diameter of the second mounting hole 5242. An annular protrusion 5243 is provided at the bottom of the second mounting hole 5242, protruding from the lower surface of the support base 523 and extending into the first clearance hole 522 to achieve sealing.
[0078] The powder pressing module 53 includes a powder pressing head 531 installed in the second mounting hole 5242 for pressing the powder in the cup 200 flat, and a pusher sleeve 532 elastically fitted around the outer periphery of the powder pressing head 531 for pushing the cup 200 downward after powder intake. The powder pressing head 531 is installed into the second mounting hole 5242 of the fixed mounting base 524 by screws. The powder pressing head 531 includes an upper powder pressing head mounting part, a middle conical connecting part, and a lower pressing part that extends into the cup 200. The diameter of the powder pressing head mounting part is smaller than the diameter of the pressing part; therefore, the middle conical connecting part has a conical structure that is smaller at the top and larger at the bottom. The powder pressing head mounting part has a threaded hole inside for screw mounting. The powder pressing head 5312 has a cylindrical structure with a flat bottom. The pusher sleeve 532 has a through hole inside that conforms to the lower end of the powder pressing head 531. The push sleeve 532 includes a first section at the upper end and a second section at the lower end. The diameter of the first section is smaller than the diameter of the second section, thus forming a stepped plane at the connection between the first and second sections. A first spring 533 is sleeved on the outer periphery of the first section. The lower end of the first spring 533 abuts against the stepped plane, and the upper end abuts against the inner wall of the second mounting hole 5242. The lower end of the second section is provided with a tapered tip 5321 with a gradually decreasing diameter that can extend into the cup 200 and achieve a contour seal with the inner wall of the cup 200. The outer wall of the tapered tip 5321 is a smooth plane.
[0079] This design includes three powder pressing modules 53, with three corresponding first clearance holes 522 on the mounting base 52. The three powder pressing modules 53 are arranged in a triangle, and the converging channel 521 is located at the center of the three powder pressing modules 53. The layout is compact and occupies very little space.
[0080] When the powder is added to the cup 200 and conveyed to the powder pressing and suction device 5 via the rotating disk 1, the powder pressing and suction device 5 starts working. Multiple cups 200 on the rotating disk 1 contain powder. The pushing module 54 simultaneously pushes the multiple cups 200 on the rotating disk 1 upwards, causing the cups 200 to enter the first clearance hole 522 on the support base 523. During the upward pushing process, the conical tip 5321 of the pushing sleeve 532 abuts against the inner wall of the cup 200, thus moving upwards, and the first spring 533 is compressed. When the cup 200 is pushed into place, the pressing part of the powder pressing head 531 presses tightly against the upper end of the powder inside the cup 200, flattening the powder. The cup mouth 201 is supported on the annular support 5221 of the first clearance hole 522, and the cup mouth 201 contacts and seals with the annular support 5221. Therefore, the outer wall of the second section of the pushing sleeve 532, the cup mouth 201, the hole wall of the first clearance hole 522, and the annular protrusion 5243 at the bottom of the mounting seat 524 together form a residual powder receiving space 55. Multiple cups 200 are located in multiple first clearance holes 55. Multiple receiving spaces 55 are formed within the mounting base 52, and these multiple receiving spaces 55 are simultaneously connected to the converging channel 521. Therefore, a powder movement channel 56 is formed inside the mounting base 52, from which powder enters the converging channel 521 through the multiple receiving spaces 55 and then enters the powder suction pipe 51 through the converging channel 521. This powder movement channel 56 is a sealed channel, and a vacuum generator is connected to the other end of the powder suction pipe 51. When the vacuum generator starts working, the air in the powder movement channel 56 is rapidly discharged, and the amount of air in the powder movement channel 56 increases accordingly. As the air volume decreases, the vacuum level of the powder movement channel 56 increases rapidly. Once a certain vacuum level is reached, the powder at the cup opening 201 of the powder movement channel 56 is sucked clean. After the work is completed, the vacuum generator stops working, and the push module 54 descends. At this time, the cup 200 tends to descend due to its own gravity, and the reset of the first spring 533 will cause the push sleeve 532 to move downward. Thus, the push sleeve 532 pushes the cup 200 down and drops it to its original position on the rotating disk 1. The powder pressing and suction action is completed, and it waits to enter the next cycle.
[0081] The film cutting and pre-sealing device 6 includes a first mounting frame 61 disposed on the outside of the rotating disk 1, a film supply module 62 fixed on the first mounting frame 61, a film cutting and pre-sealing mechanism 63 that simultaneously performs film cutting and pre-sealing actions, a traction module 64 disposed on one side of the film cutting and pre-sealing mechanism 63 for guiding the film from the film supply module 62 to the film cutting and pre-sealing mechanism 63, a film receiving module 65 disposed on the other opposite side of the film cutting and pre-sealing mechanism 63, and a second cup pushing module 66 for pushing the cup 200 into the lower part of the film cutting and pre-sealing mechanism 63.
[0082] The film cutting and pre-sealing mechanism 63 includes a linkage drive module 631 mounted on a first mounting frame 61, a first support frame 632 driven by the linkage drive module 631 to move up and down, a film cutting and pre-sealing module 633 fixed on the first support frame 632 for performing film cutting and pre-sealing actions, and a positioning module 634 located below the film cutting and pre-sealing module 633 for positioning the cup and film. The first support frame 632 includes a fourth support plate 6321 for fixing a plurality of film cutting and pre-sealing modules 633, and a fifth support plate 6323 fixed below the fourth support plate 6321 by a support column 6322. Both the fourth support plate 6321 and the fifth support plate 6323 are horizontally arranged. To improve the stability of the first support frame 632's vertical movement, several vertical guide posts 6324 are provided on the fifth support plate 6323. A first linear bearing is fitted onto each guide post 6324 at the position on the fifth support plate 6323. A sixth support plate 6325 is provided at the upper end of the fifth support plate 6323, and the upper ends of the guide posts 6324 are fixed to the sixth support plate 6325. A clearance through hole 6326 is provided in the middle of the sixth support plate 6325 to allow the fourth support plate 6321 to move vertically. A clearance opening 6327 is provided on the fifth support plate 6323 to allow the pre-sealing module 633 to move vertically. The linkage drive module 631 includes a cutting and sealing rotary motor 6311, a rotating wheel 6312 driven by the cutting and sealing rotary motor 6311, an eccentric shaft 6313 eccentrically fixed to one side of the rotating wheel 6312, a swing link 6314 rotatably mounted on the eccentric shaft 6313 at one end, and a support base 6315 fixed on the fourth support plate 6321. The other end of the swing link 6314 is rotatably mounted on the support base 6315 via a support shaft 6316. This eccentric linkage structure allows the rotary drive to be converted into a linear drive, saving space compared to a linear motor drive. The film-cutting and pre-sealing module 633 includes a first support plate 6331 located at the lower end of the fifth support plate 6323, and a plurality of first heat-sealing heads 6332 whose upper ends are fixed to the first support plate 6221 and whose lower ends extend movably to the lower side of the first support plate 6331. A plurality of cutters 6333 and a plurality of elastic pressing components 6334 for pressing the film against the cup opening are provided on the lower side of the first support plate 6331. The cutters 6333 are all movably sleeved on the outer periphery of the first heat-sealing heads 6332, and the elastic pressing components 6334 are all movably sleeved on the outer periphery of the cutters 6333. In this embodiment, three first heat-sealing heads 6332 are provided on the fourth support plate 6321. The first support plate 6331 is horizontally set, and several hanging rods 6335 are fixedly connected to the first support plate 6331. The first support plate 6331 is movably hung on the fifth support plate 6323 through the hanging rods 6335. A third spring is sleeved on the outer periphery of the hanging rods 6335. The upper end of the third spring abuts against the fifth support plate 6323 and the lower end abuts against the first support plate 6331.To improve the stability of the vertical movement of the first support plate 6331, a second linear bearing is fitted onto the guide post 6324 at the position of the first support plate 6331. Since the first heat-sealing head 6332 continuously performs heat-sealing operations, its bottom temperature is relatively high, which may affect the film-cutting pre-sealing module 633. Therefore, a heat insulation plate 6336 is provided on the lower surface of the first support plate 6331, and the heat insulation plate 6336 is provided with clearance holes for the clamping member of the elastic clamping assembly 6334. The elastic clamping assembly 6334 includes a clamping block 63341, a third sealing ring 63342 disposed at the bottom of the clamping block 63341, a guide screw 63343 whose lower end is fixed to the clamping block 63341 and whose upper end is disposed on the first support plate 6331, and a second spring 63344 sleeved around the guide screw 63343. The pressing block 63341 is provided with a heat sealing head clearance hole 63345 for the first heat sealing head 6332 to move up and down. The third sealing ring 63342 can be used to press the film at the edge of the cup mouth to ensure the integrity of the cut. The second spring 63344 can play a buffering role. The pressing block 63341 can make up-down elastic floating so that the third sealing ring 63342 can automatically and elastically adapt to the film at the edge of the cup mouth, which can press the film at the edge of the cup mouth well without damaging the film. The positioning module 634 includes a positioning plate 6341 fixed to the lower end of the guide post 6324. The positioning plate 6341 includes an upper clearance groove 6342 for the pre-sealing module 633 to extend into, a number of cup inlets 6347 for cups to extend into, a film inlet 6343 on the right side communicating with the clearance groove 6342 and for the film to enter, and a film outlet 6344 on the left side communicating with the clearance groove 6342 and for the film to flow out. The positioning plate 6341 has guide bars 6345 at both the film inlet 6343 and the film outlet 6344 to guide the film. Limiting pins 6346 are provided on the front and rear sides of the positioning plate 6341 to limit the lower position of the first support plate 6331. When the cutter 6333 descends to the lower position, the first support plate 6331 is supported against the upper end of the limiting pins 6346. The widths of the clearance groove 6342, the inlet 6343, and the outlet 6344 are all contoured to the width of the film. In this embodiment, the three inlet holes 6347 are arranged in a triangular structure, which can make full use of the film and reduce the amount of waste film cut off.
[0083] When the cup 200, after powder pressing and suction, is conveyed by the rotating disk 1 to directly below the film pre-sealing device 6, the film cutting and pre-sealing device 6 starts working. The film module 62 conveys the uncut film into the positioning module 634. At the same time, the second cup pushing module 66 below the rotating disk 1 pushes the cup upward into the cup inlet 6347 of the positioning component 34 so that the cup mouth contacts the film. The film cutting and pre-sealing module 633 starts working, and the cutting and sealing rotary motor 6311 drives the rotating wheel 6312 to drive the pendulum. The moving link 6314 causes the first support frame 632 and the first support plate 6331 to move downwards. At this time, the first heat sealing head 6332, the cutter 6333, and the elastic pressing assembly 6334 all move downwards. The elastic pressing assembly 6334 is the first to contact the film, so the elastic pressing assembly 6334 is at its lowest position. The cutting and sealing rotary motor 6311 continues to drive the elastic pressing assembly 6334 downwards and elastically presses it. The third sealing ring 63342 at the bottom of the pressing block 63341 will... The film is completely pressed against the cup rim, while the lower surface of the first support plate 6331 is restrained by the limiting pin 6346. At this time, the cutter 6333 contacts the film, and the cutting and sealing rotary motor 6311 continues to drive the cutter 6333 downward to cut the film. At this time, the first heat sealing head 6332 is still above the cup rim. After the film is cut, the cutting and sealing rotary motor 6311 continues to drive the first heat sealing head 6332 downward to contact the film and achieve pre-sealing. At the same time, the first support plate 63... 31 is always restricted to the limit pin 6346, and the third spring is compressed; after the pre-sealing is completed, the cutting and sealing rotary motor 6311 drives the rotating wheel 6312 to drive the swing linkage 6314 to make the first support frame 632 and the first support plate 6331 move upward, so that the first heat sealing head 6332, the cutter 6333 and the elastic pressing assembly 6334 move upward to return to their original positions. At the same time, the film taking module 65 rolls up the cut film to take it up, ready for the next film cutting and pre-sealing.
[0084] The heat-sealing device 7 includes a second mounting frame 71, several heat-sealing modules 72 fixed on the second mounting frame 71, and a third cup-pushing module 73 located below the rotating disk 1 for pushing the cup 200 upwards. Each heat-sealing module 72 includes a second heat-sealing head 721 for performing the heat-sealing action, a heat-sealing cylinder 722 for driving the second heat-sealing head 721 up and down, and a heat-insulating sleeve 723 fitted onto the upper end of the heat-sealing head 721 and located below the heat-sealing cylinder 722. After the film-cutting and pre-sealing device 6 completes the film-cutting and pre-sealing actions, the cup 200 is transported to the bottom of the heat-sealing device 7. After the third cup-pushing module 73 pushes the cup 200 upwards into position, the heat-sealing cylinder 722 drives the second heat-sealing head 721 downwards to contact the cup rim and achieve the heat-sealing action.
[0085] The feeding device 8 includes a waste removal conveying track 82 set on the outer periphery of the rotating disk 1 and a conveying mechanism 81 that transports the sealed finished products on the rotating disk 1 to the waste removal conveying track 82.
[0086] The conveying mechanism 81 includes a mounting base 811, a rotary conveying motor 812 fixed on the mounting base 811, a mounting plate 813 driven by the rotary conveying motor 812 to rotate, and a gripper module 814 fixed on the mounting plate 813.

The gripper module 814 includes a gripper moving bracket 8142 movably disposed above the mounting plate 813, several pairs of grippers 8143 hinged to the gripper moving bracket 8142 and extending horizontally, and a gripper cylinder 8141 that drives the gripper moving bracket 8142 to move left and right and drives the several pairs of grippers 8143 to clamp or open simultaneously; the gripper cylinder 8141 is fixedly mounted on the horizontal plate 8132; the grippers 8143 are all horizontally arranged, which is suitable for machine tools with limited vertical space and has strong applicability. The horizontal plate 8132 is provided with mutually perpendicular sliding grooves 81321 and slide rails 81328. The sliding grooves 81321 are horizontally arranged left and right, and the slide rails 81328 are arranged front and back. The gripper moving bracket 8142 is slidably arranged in the sliding grooves 81321. Each pair of grippers 8143 has a slider on its lower surface, and the slider is slidably arranged on the slide rails 81328. One end of each pair of grippers 8143's two claw bodies 81431 is hinged to the gripper moving bracket 8142 through a rotating connecting rod 8144. The first end of the rotating connecting rod 8144 is fixedly connected to the gripper moving bracket 8142, and the second end is hinged to one end of the claw body 81431. The other ends of the two claw bodies 81431 are provided with contact arc surfaces 81432 that conform to the outer wall of the cup 200. When moving cup 200 on the disc, the three grippers 8143 are horizontally positioned and need to extend into the horizontally positioned disc to grip cup 200. Therefore, the horizontal plate 8132 needs to have openings at the locations of the grippers 8143 to allow them to pass. The horizontal plate 8132 has clearance openings 81322 at the locations of the three grippers 8143. The horizontal plate 8132 has an "I"-shaped structure, including a first mounting part 81325 on the left, a crossbeam 81326 in the middle, and a second mounting part 81327 on the right. Both the first mounting part 81325 and the second mounting part 81327 are provided with slide rails 81328. The slide groove 81321 is fixed on the crossbeam 81326 in the middle, and the gripper moving bracket 8142 is slidably disposed in the slide groove 81321.Correspondingly, the gripper moving bracket 8142 includes a first extension rod 81421 extending forward, a second extension rod 81422 extending backward, and a third extension rod 81423 extending from the middle to the right.

If a defective product appears on a conveyor track 821, the reject driving component drives the reject plate 8221 to flip upwards, and the defective product falls directly into the reject receiving bin 8224 below the reject plate 8221. If each conveyor track 821 carries good products, the reject plate 8221 is flush with the track plane of the conveyor track 821 and forms part of the conveyor track 821, conveying the good products to the next conveyor line, thus completing the transport of good products.
[0088] After heat sealing, the filled finished product is obtained. When the finished product is conveyed to the unloading device 8, the rotary conveying motor 812 drives the rotary arm 8131 to rotate, causing the horizontal plate 8132 to extend into the disc, so that the finished product is located inside the gripper 8143. The gripper cylinder 8141 drives the gripper moving bracket 8142 to move to the left. Each pair of grippers 8143 slides on the slider and moves closer to each other to clamp the cup body. The rotary conveying motor 812 drives the rotary arm 8131 to rotate in the opposite direction to transport the finished product taken from the disc to the waste conveying track 82. The gripper cylinder 8142 drives the gripper moving bracket to move to the left. The frame 8142 moves in the opposite direction, and each pair of grippers 8143 slides on the slider and moves away from each other, so that the finished product enters the rejection conveyor track 82. If a defective product appears on a certain conveyor track 821, the rejection drive drives the rejection plate 8221 to flip up, and the defective product falls directly into the waste receiving bin 8224 below the rejection plate 8221. If each conveyor track 821 is conveying good products, the rejection plate 8221 is flush with the track plane of the conveyor track 821 and forms part of the conveyor track 821, conveying the finished product to the next conveyor line, completing the conveying of the finished product.

In this embodiment, the transmission shaft mechanism 22 includes three parallel transmission shafts 221. Adjacent transmission shafts 221 are rotated via a pair of sprocket and chain assemblies 222. One transmission shaft 221 is fixed to the output shaft of the drive motor. Each of the three transmission shafts 221 has a drive cam 223 that corresponds to and engages with the first cup-pushing module 48, the second cup-pushing module 66, and the third cup-pushing module 73. Each of the first cup-pushing module 48, the second cup-pushing module 66, and the third cup-pushing module 73 has a transmission roller that engages with the drive cam 223. The transmission shafts 221 drive the drive cam 223 to rotate, and the drive cam 223, with its varying diameter outer circumference, drives the transmission roller to move up and down. The first cup-pushing module 48, the second cup-pushing module 66, and the third cup-pushing module 73 have the same structure and each includes a cup-pushing holder and several cup-pushing sleeves fixed to the cup-pushing holder.
[0090] The disc-type high-efficiency fully automatic filling and sealing machine 100 also includes an air blowing device 9 located between the cup dropping device 3 and the feeding device 4 for blowing air into the cup 200; a sealing detection device located after the heat sealing device 7 for detecting whether the seal is complete; a weighing device 20 for detecting whether the weight of the sealed finished product meets the requirements; and a cleaning device 30 located after the unloading device 8 for cleaning the surface of the rotating disc 1. The weighing device 20 is equipped with a gravity sensor. The air blowing device 9 serves two purposes: firstly, it blows air to clean the cup, and secondly, it fills the cup with inert gas to prevent the powder inside the cup from deteriorating.
[0091] When using the disc-type high-efficiency fully automatic powder filling and sealing machine 100 provided in this solution, cups 200 are placed in the storage bin 321, and the cups 200 are pushed towards the cup rack 32 so that the cups 200 are stacked in the cup rack 32 with their openings facing upwards. The cup dropping drive mechanism 34 of the cup dropping device 3 drives the cup separating module 33 to complete the cup dropping action. The air blowing device 9 blows air into the inside of the cups 200. The cups 200 are transported by the rotating disc 1 to the bottom of the feeding device 4, and the feeding module 46 of the feeding device 4 completes the feeding action. When the feeding process is complete, and the powder is conveyed to the bottom of the powder pressing and suction device 5 via the rotating disk 1, the powder pressing and suction device 5 starts working. The powder pressing module 53 flattens the powder in the cup and simultaneously suctions the powder. When the cup 200, after powder pressing and suction, is conveyed to the bottom of the film pre-sealing device 6 via the rotating disk 1, the film cutting and pre-sealing device 6 starts working. The cutter 6333 of the film cutting and pre-sealing device 6 cuts the film, and the first heat sealing head 6332 pre-seales the cup opening. After the sealing device 6 completes the film cutting and pre-sealing actions, the cup 200 is conveyed to the bottom of the heat sealing device 7. The third cup pushing module 73 pushes the cup 200 upward into position, and then the heat sealing cylinder 722 drives the second heat sealing head 721 to move downward and contact the cup mouth to achieve the heat sealing action. After heat sealing is completed, the sealing detection device checks whether the cup mouth heat sealing is complete, and the weighing device 20 checks whether the weight of the sealed finished product meets the requirements. After heat sealing is completed, the filled finished product is obtained. When the finished product is conveyed to the unloading device 8, The conveying mechanism 81 transports the heat-sealed finished products to the rejection conveying track 82. If a defective product appears on a certain conveying track 821, the rejection drive drives the rejection plate 8221 to flip upward, and the defective product falls directly into the waste receiving bin 8224 below the rejection plate 8221. If each conveying track 821 is carrying good products, the rejection plate 8221 is flush with the track plane of the conveying track 821 and forms part of the conveying track 821, thus conveying the good products to the next conveying line and completing the conveying of good products.
