Description

Technical field

[0001] The utility model belongs to the technical field of powder filling, in particular to a staggered feeding device suitable for filling multiple material cups with small spacing. [Background Technology]

[0002] After coffee powder is produced, it needs to be added to cups and then sealed to form coffee capsules. To improve filling and sealing efficiency, existing filling machines are capable of filling and sealing multiple cups simultaneously. Therefore, it is necessary to design a corresponding feeding device that can simultaneously feed powder to multiple cups without leakage or clogging.

[0003] In the prior art, a new type of integrated filling machine disclosed in Chinese patent authorization announcement number CN216709877U includes a frame, a chain transmission structure, a coil sheet traction and feeding device, a fixed-point heating device, a sheet forming device, an easy-tear punching device, a material filling device, a film release mechanism, a heat sealing machine, a cutting mechanism and a belt line. The material filling device includes an upper mounting plate mounted on the top of the frame, a vacuum loader mounted on the upper mounting plate and a mixing and unloading barrel. The two discharge ports at the lower part of the vacuum loader are connected to the mixing and unloading barrel through a pneumatic butterfly valve. The lower ends of the two mixing and unloading barrels are each provided with a row of three-station unloading ports, and the unloading ports at the two mixing and unloading barrels are staggered. Although this solution can realize the simultaneous feeding of multiple material cups, it still has the following problems:

[0004] (1) The two mixing and discharging barrels are set separately on the left and right, and both need to be provided with material pipes connected to the two discharge ports at the bottom of the vacuum feeder. The material filling device occupies a large space in the length direction, resulting in a long length of the entire filling machine and a large space occupied;

[0005] (2) The lower end of the mixing barrel is provided with a row of three-station feeding ports, and the feeding port is only provided with a spiral rotating feeding screw. The screw will only rotate when feeding, and incidentally, the powder in the feeding barrel will be stirred. Since it is necessary to feed the three cups at the same time, if stirring is only performed when feeding, there will be insufficient stirring, powder blockage, difficulty in screw movement, and inconsistent feeding of the three cups, or even the problem of failure to discharge the material from the lower end of the screw.

[0006] (3) The material filling device is located directly above the chain transmission structure. If the material filling device is to be cleaned or repaired, it is necessary to manually enter the interior of the frame and come to the top of the chain transmission structure to clean or repair the material filling device. This operation is difficult and inefficient.

[0007] Therefore, it is necessary to provide a staggered feeding device suitable for filling multiple material cups with small spacing to solve the above technical problems. [Utility Model Content]

[0036] Please refer to Figure 1-Figure 3The present embodiment is a staggered feeding device suitable for filling multiple material cups with small spacing. The staggered feeding device 3 suitable for filling multiple material cups with small spacing includes a lifting frame 31, a lifting drive member 32 for driving the lifting frame 31 to move up and down, a mounting frame 33 movably arranged on the lifting frame 31, a receiving hopper 34 arranged below the mounting frame 33, a feeding pipe 35 arranged on the mounting frame 33 and conveying powder to the receiving hopper 34, and a stirring module 36 and a feeding module 37 jointly arranged on the mounting frame 33. The stirring module 36 stirs the powder in the receiving hopper 34, and the feeding module 37 adds the powder in the receiving hopper 34 to the material cup in a quantitative manner. Several feeding modules 37 are staggered and arranged to form at least two rows, and at least two feeding modules 37 are provided on each row.

[0037] In this embodiment, six material cups are arranged in each row on the conveyor line, and six feeding modules 37 are arranged accordingly in this scheme. The six feeding modules 37 are divided into two rows, left and right, and three feeding modules 37 are arranged in each row. The three feeding modules 37 in the left row are staggered with the three feeding modules 37 in the right row. For example, the three feeding modules 37 in the right row simultaneously complete the feeding of the first, third and fifth material cups in the right row. At the same time, the three feeding modules 37 in the left row simultaneously complete the feeding of the second, fourth and sixth material cups on the adjacent left. Multiple feeding modules 37 are staggered and divided into two rows and compactly installed on a mounting frame 33, which can save space. Moreover, the six feeding modules 37 are divided into two rows to fill and complete the feeding of six material cups at the same time. It is suitable for situations where there are multiple material cups and the spacing between each material cup is small. Therefore, this scheme can not only solve the problem that the spacing between material cups is small and it is difficult to feed at the same time, but also the layout of the entire feeding device is compact and saves space.

[0038] In other embodiments, the number of cups in each row and the number of feeding modules 37 on the conveyor line can be set according to the actual number, and several feeding modules 37 are staggered and distributed to fill in several rows, which is not limited here. For example, there are nine feeding modules 37, and the nine feeding modules 37 are divided into three rows on the left and right, and each of the three rows on the left and right is provided with three feeding modules 37. The three feeding modules 37 in each row are staggered. For example, the three feeding modules 37 in the right row simultaneously complete the feeding of the first, fourth and seventh cups in the right row. At the same time, the three feeding modules 37 in the middle row simultaneously complete the feeding of the second, fifth and eighth cups on the adjacent left. At the same time, the three feeding modules 37 in the left row simultaneously complete the feeding of the third, sixth and ninth cups on the adjacent left. The nine feeding modules 37 are divided into three rows for filling and simultaneously complete the feeding of nine cups.

[0039] The lifting drive 32 is configured to drive the lifting frame 31 to move the stirring module 36 and the feeding module 37 up and down, thereby positioning the stirring module 36 and the feeding module 37 above the material cup to add powder into the material cup. The lifting drive 32 can be configured to be driven by a motor, a cam, or other driving methods, which are not limited here.

[0040] The mounting frame 33 is movably arranged on the lifting frame 31 in the forward and backward directions and is locked by a locking assembly 38. Slide rails 333 are provided on both sides of the mounting frame 33. The lifting frame 31 is provided with a support rod 311 that matches the slide rails 333. The lower end of the support rod 311 is provided with a plurality of sliders 312, and the sliders 312 are slidably arranged on the slide rails 333.

[0041] The locking assembly 38 includes a support plate 381 connected to the mounting frame 33 and the lifting frame 31, and a screw 382 arranged on the support plate 381 and extending horizontally. When the stirring module 36 and the feeding module 37 need to be replaced or repaired, the screw 381 is loosened and the mounting frame 33 is pulled out. Compared with the existing technology, during maintenance, it is not necessary for humans to enter the interior of the frame and come to the top of the chain transmission structure. The mounting frame 33 can be directly pulled out. The human body can stand on the side of the chain transmission structure to complete the maintenance work of the stirring module 36 and the feeding module 37. The operation is simple and convenient. Moreover, in order to facilitate pulling out the mounting bracket 33, a handle 331 is provided at the outer end of the mounting bracket 33. After maintenance is completed, the mounting bracket 33 is pushed inward to position the stirring module 36 and the feeding module 37 above the material cup. A positioning pin 332 is provided on the side of the mounting bracket 33. When the mounting bracket 33 is pushed inward so that the positioning pin 332 abuts against the screw 382, ​​it means that the mounting bracket 33 has moved inward into place. At this time, the stirring module 36 and the feeding module 37 are just positioned above the material cup, which is convenient for subsequent feeding operations.

[0042] The stirring module 36 includes a plurality of stirring shafts 361 whose lower ends extend into the receiving hopper 34 , and a pair of stirring blade assemblies 362 are installed on both sides of the stirring shafts 361 .

[0043] The feeding module 37 includes a feeding transmission shaft 374 inserted into the inside of the stirring shaft 361, a feeding screw 371 installed at the lower end of the feeding transmission shaft 374 and extending out from the upper and lower ends of the stirring shaft 361, a feeding motor 372 arranged on the mounting frame 33 and driving the feeding transmission shaft 374 and the feeding screw 371 to rotate, and a plurality of feeding nozzles 373 arranged at the lower end of the receiving hopper 34 and provided with corresponding lower ends of the feeding screw 371.

[0044] The stirring module 36 also includes a driven pulley 367 fixed to the upper end of the stirring shaft 361, a stirring motor 363 mounted on the mounting frame 33, and a driving pulley 364 driven by the stirring motor 363. In this embodiment, six stirring shafts 361 are provided, and the six stirring shafts 361 are staggered in two rows on the left and right sides, so six driven pulleys 367 are provided. The driving pulley 364 and the six driven pulleys 367 are connected together by a plurality of meshing gears 365 to achieve meshing transmission. The driving pulley 364 and the plurality of driven pulleys 367 are located above the mounting frame 33. The meshing gears 365 are rotatably mounted on a rotating shaft, which is fixed to the mounting frame 33.

[0045] The interior of the stirring shaft 361 is provided with an axial hole extending through the upper and lower ends and through which the feeding drive shaft 374 passes. A bearing sleeve 366 is fixed to the upper surface of the mounting bracket 33 via studs. Several first bearings are provided on the outer periphery of the stirring shaft 361. The stirring shaft 361 is mounted within the bearing sleeve 366 via the first bearings. A first sealing ring is provided on the outer periphery of the stirring shaft 361 to seal between the stirring shaft 361 and the bearing sleeve 366. Limiting sleeves are provided between the several first bearings to limit the position of the first bearings. The upper end of the bearing sleeve 366 is fixed to the mounting bracket 33, and the lower end extends into the receiving hopper 34. The first sealing ring is located inside the lower end of the bearing sleeve 366 and is provided to seal between the stirring shaft 361 and the bearing sleeve 366, preventing powder from entering the bearing sleeve 366 and hindering the rotation of the stirring shaft 361, thereby affecting the stirring of the powder in the receiving hopper 34.

[0046] The stirring blade assembly 362 includes a first stirring blade 3621 fixed on one side of the stirring shaft 361 and a second stirring blade 3622 fixed on the other opposite side of the stirring shaft 361. The blade body of the first stirring blade 3621 extends downward and extends into the upper end of the feeding nozzle 373, which can fully stir the powder beside the feeding screw 371 and the powder entering the feeding nozzle 373, and can prevent the feeding screw 371 from clumping and clogging during feeding; the second stirring blade 3622 is provided with two blade bodies facing each other up and down, which can fully stir the powder in the receiving hopper 34, and can prevent the powder entering the feeding nozzle 373 from clumping and clogging.

[0047] The feeding drive shaft 374 is mounted within the stirring shaft 361 via a second bearing. A second sealing ring is sleeved around the lower end of the feeding drive shaft 374. A mounting groove for the second bearing and the second sealing ring is provided within the lower end of the stirring shaft 361. The second sealing ring is provided to seal the feeding drive shaft 374 with the stirring shaft 361, preventing powder from entering between the stirring shaft 361 and the feeding drive shaft 374 and obstructing their rotation, thereby preventing the mixing and feeding of the powder. The feeding screw 371 is provided with a spiral groove structure on its outer circumference. This structure allows for quantitative addition of powder to the feeding nozzle 373. Furthermore, when feeding is not required, the feeding motor 372 stops driving the feeding screw 371, storing the powder within the spiral groove of the feeding screw 371 and preventing it from falling.

[0048] When the staggered feeding device 3 provided by the present invention is applied and is suitable for filling multiple material cups with small spacing, the powder in the storage bin (not shown in the figure) enters the receiving hopper 34 below through the feeding pipe 35, and the stirring motor 363 drives the driving wheel 364 to drive the stirring shaft 361 to rotate, thereby driving a pair of stirring blade assemblies 362 fixed on the stirring shaft 361 to stir the powder in the receiving hopper 34, so that the powder enters the spiral groove of the feeding screw 371 evenly. When feeding is needed, the weight of the feeding can be adjusted by controlling the number of revolutions of the feeding motor 372. The six feeding motors 372 drive the six feeding screws 371 at the same time. The rod 371 rotates to allow the powder to enter the cup below through the feeding nozzle 373. The three feeding modules 37 in the right row simultaneously complete the feeding of the first, third and fifth cups in the right row. At the same time, the three feeding modules 37 in the left row simultaneously complete the feeding of the second, fourth and sixth cups on the adjacent left sides, completing the feeding of six cups at the same time. When no feeding is needed, the pair of stirring blade assemblies 362 on the stirring shaft 361 continue to stir the powder in the receiving hopper 34, and the feeding motor 372 stops driving the feeding screw 371 to rotate. The powder is stored in the spiral groove of the feeding screw 371 and the powder will not fall.

[0049] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
