[0033] When the present invention is in use, the bagged drag reducer is put into the feeding bin 4 through the feeding port 6, and the drag reducer is supported by the adjacent partition plates 11 and push plates 12; the cutting shaft is rotated, and the cutting shaft divides the packaging bag through the inner cutting knife 10, so that the drag reducer in the packaging bag flows into the space between adjacent partition plates 11; at the same time, a pair of push plates 12 rotate along the dividing shaft to squeeze the packaging bag, so that the drag reducer in the packaging bag quickly flows out; in addition, the rotating bin 15 is rotated, and the rotating bin 15 drives the packaging bag to rotate through the partition plates 11, push plates 12, etc. and contacts the outer cutting knife 13, so that the outer cutting knife 13 divides the packaging bag again; the packaging bag is separated by the cooperation of the inner cutting knife 10 and the outer cutting knife 13, and the packaging bag is reciprocally squeezed by the cooperation of a pair of push plates 12, so that the drag reducer in the packaging bag flows into the storage bin 1 for storage, realizing the feeding process of the storage bin 1; in addition, through the cooperation of the bag discharging bin 7 and the bag discharging structure 8, the packaging bag is assisted to separate from the feeding bin 4, realizing the collection of the packaging bag.

[0034] Further, as Figure 3 shown, in order to intermittently rotate the rotating bin 15, an intermittent motor 5 is fixedly connected to the feeding bin 4, a dial rod 17 is fixedly connected to the output end of the intermittent motor 5, and a sheave 16 corresponding to the dial rod 17 is coaxially fixedly connected to the rotating bin 15; through the cooperation of the dial rod 17 and the sheave 16, the rotating bin 15 intermittently rotates; a limiting disk is coaxially fixedly connected to the dial rod 17, and a limiting groove corresponding to the limiting disk is provided on the sheave 16, and the sheave 16 is limited through the cooperation of the limiting disk and the limiting groove to improve the stability of the sheave 16 and the rotating bin 15.

[0035] Further, as Figure 4 and Figure 6As shown, in order to synchronously rotate multiple said cutting shafts, a driving motor 19 is fixedly connected to the feeding bin 4, the output end of the driving motor 19 is fixedly connected to a driving wheel 22, and an external gear ring 21 meshing with the driving wheel 22 is rotatably connected to the feeding bin 4; a synchronous gear ring 23 is rotatably connected in the rotating bin 15, and cutting wheels 26 meshing with the synchronous gear ring 23 are coaxially and fixedly connected to multiple said cutting shafts; the external gear ring 21 is coaxially and fixedly connected to an internal gear ring 18, and a driving wheel 20 coaxially and fixedly connected to one of the cutting wheels 26 is meshed with the internal gear ring 18.

[0036] Specifically, when the cutting shaft needs to rotate, start the driving motor 19, the driving motor 19 drives the driving wheel 22 to rotate, the driving wheel 22 drives the external gear ring 21 to rotate, and the external gear ring 21 drives the driving wheel 20 to rotate through the internal gear ring 18; the driving wheel 20 drives one of the cutting wheels 26 to rotate, and the cutting wheel 26 drives the remaining cutting wheels 26 to rotate synchronously through the synchronous gear ring 23, thereby driving the cutting shafts to rotate synchronously, and the cutting shafts cut the drag reducer packaging bags through the internal cutting knives 10.

[0037] Furthermore, as Figure 5 and Figure 6 shown, in order to make the push plate 12 reciprocate along the cutting shaft, multiple sliders 29 evenly distributed along the circumference are slidably connected to the rotating bin 15, and the multiple sliders 29 slide radially of the rotating bin 15 as the gear ring rotates, and a pair of push rods 14 are rotatably connected to each of the multiple sliders 29, and the pair of push rods 14 are respectively rotatably connected to a pair of push plates 12; by making the sliders 29 slide radially of the rotating bin 15, the sliders 29 drive the push plates 12 to rotate along the cutting shaft through the push rods 14.

[0038] Furthermore, in order to make the multiple sliders 29 slide radially of the rotating bin 15 synchronously, a sleeve is rotatably connected to the rotating bin 15, and multiple rocker arms 27 are evenly distributed along the circumference of the sleeve; a traction rod 28 is rotatably connected to each of the multiple rocker arms 27, and the other end of the traction rod 28 is rotatably connected to the slider 29; when the sleeve rotates by a certain angle, the sleeve drives the traction rod 28 to rotate through the rocker arms 27, and the traction rod 28 drives the slider 29 to slide radially of the rotating bin 15.

[0039] Further, to enable the sleeve to rotate reciprocally within a certain angular range, an output wheel 24 meshing with the synchronous gear ring 23 is also rotatably connected within the rotating chamber 15. The output wheel 24 is coaxially and fixedly connected with a synchronous crank 30. A connecting rod 25 is rotatably connected to the synchronous crank 30, and the other end of the connecting rod 25 is rotatably connected to one of the rockers 27. As the synchronous gear ring 23 rotates, the output wheel 24 rotates within the rotating chamber 15. The output wheel 24 drives the synchronous crank 30 to rotate. The synchronous crank 30, the connecting rod 25, and the rocker 27 form a crank-rocker mechanism, enabling the synchronous crank 30 to drive the rocker 27 to swing within a certain angular range through the connecting rod 25, and the rocker 27 drives the sleeve to reciprocally swing within a certain angular range.

[0040] Further, inner notches corresponding to the inner cutting knife 10 and the outer cutting knife 13 are provided on the push plate 12, and outer notches corresponding to the outer cutting knife 13 are provided on the partition plate 11. Inner through-holes are evenly distributed on the push plate 12, and outer through-holes are evenly distributed at the end of the partition plate 11 near the outer notch. Through the setting of the inner through-holes, the drag reducer can flow within the partition plate 11. Through the setting of the outer through-holes, when the drag reducer rotates with the partition plate 11, the drag reducer can flow into the other side of the partition plate 11 through the outer through-holes on the partition plate 11. After the drag reducer packaging bag is divided, the drag reducer can quickly flow to the storage bin 1 through the outer through-holes. A discharge port communicating with the storage bin 1 is provided at the bottom of the feeding bin 4, and a filter screen 9 corresponding to the discharge port is provided on the feeding bin 4. The drag reducer is filtered through the filter screen 9 to prevent packaging bag debris from flowing into the feeding bin 4.

[0041] Further, as Figure 9 and Figure 10 shown, the bag discharging structure 8 includes path structures provided at both ends of the bag discharging chamber 7. The output end of the path structure is connected with a connecting frame 35, and the path structure can drive the connecting frame 35 to move along a semicircular path. A clamping chamber 36 capable of reciprocally swinging is rotatably connected to the connecting frame 35, and a clamping structure for clamping the packaging bag is provided on the clamping chamber 36. A swinging motor 37 is fixedly connected to the connecting frame 35, and the output end of the swinging motor 37 is coaxially and fixedly connected with the clamping chamber 36.

[0042] The path structure drives the clamping structure to move along a semicircular path, enabling the clamping structure to first move along the circumference of the semicircle to the position in contact with the packaging bag. The swinging motor 37 drives the clamping structure on the clamping chamber 36 to extend into the feeding bin 4 to clamp the packaging bag. Secondly, the radial movement during the movement along the semicircular path drives the packaging bag away from the feeding bin 4, causing the packaging bag to flow out through the feeding bin 4 and the bag discharging chamber 7.

[0043] Further, the path structure includes a path motor 31 fixedly connected to the bag outlet bin 7, and an input rod 32 is fixedly connected to the output end of the path motor 31; both ends of the bag outlet bin 7 are rotatably connected with sliding cylinders 34, and sliding rods 33 perpendicular to the connecting frame 35 are slidably connected to a pair of the sliding cylinders 34; when the path structure is in use, the path motor 31 is started, the path motor 31 drives the input rod 32 to rotate, while the input rod 32 drives the sliding rod 33 to slide along the sliding cylinder 34, the sliding rod 33 drives the sliding cylinder 34 to rotate along the bag outlet bin 7, so that the sliding rod 33 drives the connecting frame 35 to move along a semi-circular path.

[0044] Further, as Figure 11 and Figure 12 shown, the clamping structure includes a clamping motor 38 fixedly connected to the clamping chamber 36, and a driving bevel gear 41 is fixedly connected to the output end of the clamping motor 38; a synchronous shaft is rotatably connected in the clamping chamber 36, and a plurality of connecting bevel gears 42 are fixedly connected to the synchronous shaft, and the driving bevel gear 41 meshes with one of the connecting bevel gears 42; a plurality of the connecting bevel gears 42 are all meshed with driven bevel gears 43, and a plurality of the driven bevel gears 43 are all coaxially fixedly connected with double-direction cranks 44; a moving rod 45 is rotatably connected to the double-direction crank 44, a clamping block 46 slidably connected to the clamping chamber 36 is rotatably connected to the moving rod 45, and a plurality of clamping rods 39 are fixedly connected to the clamping block 46; a guiding rod 40 is fixedly connected in the clamping chamber 36, and the clamping block 46 is slidably connected to the guiding rod 40.

[0045] When the clamping structure is in use, the clamping motor 38 is started, the clamping motor 38 drives the driving bevel gear 41 to rotate, the driving bevel gear 41 drives one of the connecting bevel gears 42 to rotate, and the connecting bevel gear 42 drives the remaining connecting bevel gears 42 to rotate through the synchronous shaft; the connecting bevel gear 42 drives the double-direction crank 44 to rotate through the driven bevel gear 43, the double-direction crank 44 drives the clamping block 46 to slide along the guiding rod 40 through the moving rod 45, and the clamping block 46 clamps the packaging bag through the clamping rods 39.

[0046] The working process of the present invention is as follows:

[0047] When the present invention is in use, the bagged drag reducer is put into the feeding bin 4 through the feeding port 6, and the drag reducer is supported by the adjacent partition plates 11 and the pushing plates 12; the driving motor 19 is started, the driving motor 19 drives the driving wheel 22 to rotate, the driving wheel 22 drives the external gear ring 21 to rotate, and the external gear ring 21 drives the driving wheel 20 to rotate through the internal gear ring 18; the driving wheel 20 drives one of the cutting wheels 26 to rotate, the cutting wheel 26 drives the remaining cutting wheels 26 to rotate synchronously through the synchronous gear ring 23, thereby driving the cutting shaft to rotate synchronously, and the cutting shaft cuts the drag reducer packaging bag through the internal cutting knife 10, so that the drag reducer in the packaging bag flows between the adjacent partition plates 11.

[0048] Meanwhile, the synchronous gear ring 23 drives the output wheel 24 to rotate. The output wheel 24 rotates the synchronous crank 30 synchronously. The synchronous crank 30 drives the rocker 27 to swing within a certain angle range through the connecting rod 25. The rocker 27 drives the sleeve to reciprocate within a certain angle range. The sleeve drives a plurality of traction rods 28 to rotate through a plurality of rockers 27. The traction rod 28 drives the slider 29 to slide radially along the rotating chamber 15. The slider 29 drives the push plate 12 to rotate along the cutting shaft through the push rod 14, so that a pair of push plates 12 cooperate to squeeze the packaging bag, and the drag reducer in the packaging bag flows out quickly.

[0049] In addition, the intermittent motor 5 is started. The intermittent motor 5 drives the rotating chamber 15 to rotate a certain angle through the cooperation of the dial rod 17 and the grooved wheel 16. The rotating chamber 15 drives the packaging bag to rotate through the partition plate 11, the push plate 12, etc. and contacts the outer cutting knife 13, so that the outer cutting knife 13 divides the packaging bag again. During the rotation of the partition plate 11, the drag reducer flows into the storage bin 1 through the outer through holes and the filter screen 9 on the partition plate 11 under the action of the partition plate 11 and its own gravity.

[0050] When the packaging bag rotates with the partition plate 11 to correspond to the bag outlet bin 7, the path motor 31 is started. The path motor 31 drives the input rod 32 to rotate. While the input rod 32 drives the slide rod 33 to slide along the sliding cylinder 34, the slide rod 33 drives the sliding cylinder 34 to rotate along the bag outlet bin 7, so that the slide rod 33 drives the connecting frame 35 to move along a semicircular path. The clamping structure first moves along a semicircular circumference to the contact position with the packaging bag, and the clamping structure on the clamping chamber 36 is driven by the swing motor 37 to extend into the feeding bin 4 to clamp the packaging bag. Secondly, the radial movement during the movement along the semicircular path drives the packaging bag away from the feeding bin 4, so that the packaging bag flows out through the feeding bin 4 and the bag outlet bin 7.
