Description

Technical Field

[0001] This invention relates to the field of packaging machine technology, and in particular to a feeding device and method of using a vertical roller packaging machine. Background Technology

[0002] In the operation of vertical roller packaging machines, the feeding device is a key component, and its performance directly affects the overall working efficiency and packaging quality of the packaging machine. Traditional feeding devices for vertical roller packaging machines have many problems.

[0003] In the feeding stage of vertical roller packaging machines, existing technologies have several shortcomings. During raw material feeding, accumulation and blockage often occur due to a lack of effective control, affecting the smoothness of the feeding process. Regarding raw material screening, it is difficult to ensure uniform particle size; uneven raw materials can easily affect the sealing performance after later filling and packaging. During the feeding process, uneven material delivery leads to material accumulation in the feeding pipe, affecting the uniformity of material injection into the packaging bags. Furthermore, during the feeding process, raw materials tend to accumulate in specific areas, such as the inclined groove and inclined panel, further hindering the feeding process. These problems combined reduce the working efficiency and packaging quality of vertical roller packaging machines. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing raw material feeding methods, such as easy clogging, uneven screening, uneven conveying, and raw material accumulation in specific areas. This invention proposes a feeding device and method for use in a vertical roller packaging machine. The design starts from basic needs and forms a hierarchical protection: the core layer is intermittent cam discharge to prevent clogging; the extended layer adds pin-column vibration screening to improve uniformity; and the auxiliary layer integrates track groove vibration conveying and airbag blowing to prevent accumulation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device for a vertical roller packaging machine includes a vertical roller packaging machine body and a feeding pipe fixed inside the vertical roller packaging machine body. An annular partition is fixed inside the feeding pipe, and a rectangular groove is provided inside the annular partition. A feeding plate is slidably disposed inside the rectangular groove. A reciprocating structure is provided inside the feeding pipe for driving the feeding plate to reciprocate, so that the feeding plate and the annular partition cooperate to intermittently complete the injection of raw materials. It also includes at least two bases fixed to the top of the vertical roller packaging machine body, with a feeding cylinder fixed to the top of the bases, and a rotating column rotatably connected to the top of the vertical roller packaging machine body. The top of the rotating column extends rotatably into the feeding cylinder, and a filter screen and a screening structure for driving the filter screen to vibrate are provided inside the feeding cylinder. It also includes a rotating disk fixed to the outer wall of the rotating column and rotatably connected to the inner wall of the bottom of the feeding cylinder. A discharge pipe is fixedly inserted through one side of the feeding cylinder. One end of the discharge pipe is engaged with the rotating disk to transport the raw material into the discharge pipe by means of centrifugal force. The other end of the discharge pipe extends into the feeding pipe. The top of the vertical roller packaging machine body is provided with a vibration structure for driving the discharge pipe to vibrate.

[0006] In one possible design, the reciprocating moving structure includes two horizontal plates fixed inside the feeding tube and located below the feeding plate. A sliding rod slides through each of the two horizontal plates. A fixed plate, fixedly connected to the bottom of the feeding plate, is fixed to one end of each sliding rod that is close to the other. A spring, sleeved on the outer wall of the sliding rod, is provided between the fixed plate and the adjacent horizontal plate. A rotating shaft, located between the two fixed plates, is rotatably connected inside the feeding tube. A cam is fixedly sleeved on the outer wall of the rotating shaft. The cam cooperates with the two fixed plates to drive the feeding plate to reciprocate linearly. Inclined slots are provided on both sides of the feeding plate.

[0007] In one possible design, the screening structure includes a ring disposed inside the discharge cylinder and a plurality of pads fixed to the inner wall of the discharge cylinder for supporting the ring. The filter screen is fixed inside the ring, and two arc-shaped plates are fixed to the bottom of the filter screen. Each of the two arc-shaped plates has an inclined surface I on one side that is close to each other. The outer wall of the rotating column is fixedly fitted with a pin that cooperates with the inclined surface I, for pulling down the filter screen to make it vibrate when rotating.

[0008] In one possible design, the vibration structure includes a fixed shaft fixed to the top of the vertical roller packaging machine body, a rotating plate rotatably sleeved on the outer wall of the fixed shaft, a mounting column located below the discharge pipe fixed on one side of the top of the rotating plate, a ball bearing rotatably mounted on the top of the mounting column, and a plurality of semi-circular rubber protrusions equidistantly arranged around the fixed shaft fixed at the bottom of the discharge pipe. The ball bearings cooperate with the semi-circular rubber protrusions to drive the discharge pipe to vibrate when the rotating plate rotates.

[0009] In one possible design, the vibration structure further includes a sliding plate slidably disposed at the bottom of the discharge cylinder, a disc located below the sliding plate being fixedly sleeved on the outer wall of the rotating column, the top of the disc being provided with a hexagonal track groove, a pin being fixedly fixed at the bottom of the sliding plate on the side near the rotating column, the pin being slidably engaged with the hexagonal track groove, a protruding post being fixedly fixed at the top of the sliding plate on the side away from the pin, and a strip groove being provided inside the rotating plate that slidably engages with the protruding post.

[0010] In one possible design, a conical platform fitted onto the outer wall of the rotating column is fixed to the top of the rotating disk.

[0011] In one possible design, the discharge pipe is provided with an inclined surface II.

[0012] In one possible design, the top of the annular partition has two inclined panels fixed, and each of the two inclined panels is slidably provided with a lever that is fixedly connected to the feed plate.

[0013] In one possible design, the feeding plate has a cavity, and the inner walls of the two opposite sides of the cavity are provided with air outlets that communicate with the corresponding inclined slots. The inner walls of the two horizontal plates that are close to each other are fixed with airbags. The airbags cooperate with the adjacent fixed plates. The top of the airbag is provided with an air outlet pipe that communicates with the cavity, and the bottom of the airbag is provided with an air inlet pipe. Both the air inlet pipe and the air outlet pipe are provided with one-way valves. After several hours of continuous operation testing, the airbag leakage failure rate is low, and the purging method does not damage the raw materials.

[0014] In this invention, the raw material conveying and discharge pipe vibration are synchronously achieved by a single power source of the rotating column, which reduces the number of driving components, lowers equipment energy consumption and size, avoids synchronization errors of multiple driving sources, ensures that the vibration and conveying rhythm are matched, and improves the uniformity of raw material conveying.

[0015] This application discloses a method for using a feeding device for a vertical roller packaging machine, comprising the following steps: S1. Raw material fixing and screening: Place the ring in the feeding cylinder, support it with pads, and fix the ring with fixing bolts and nuts; feed the raw material onto the filter screen; start the motor to drive the rotating column to rotate, the rotating column drives the pin to rotate, the pin and the inclined plane I move the arc plate down, thereby pulling the filter screen down. When the pin disengages from the inclined plane I, the filter screen resets under its own toughness, generating vibration, completing the raw material screening and ensuring uniform particle size distribution; S2. Raw Material Discharge and Vibration: The screened raw material falls onto the conical platform and flows towards the outer circumference under the action of the inclined surface of the conical platform; the rotating column drives the rotating disk and the conical platform to rotate, and the raw material approaches the inner wall of the discharge cylinder under the action of centrifugal force and is discharged to the feed pipe through the discharge pipe; at the same time, the rotating column drives the disk to rotate, and the disk drives the sliding plate to move back and forth in a straight line through the pin shaft and the track groove. The sliding plate drives the rotating plate to swing back and forth around the fixed axis through the sliding engagement of the convex column and the strip groove. The rotating plate drives the discharge pipe to vibrate through the contact of the ball bearings and the rubber convex blocks, so that the raw material enters the feed pipe evenly along the inclined surface II, avoiding accumulation and blockage; S3. Intermittent Discharge and Anti-clogging: When injecting raw materials into the packaging bag, a small motor drives the rotating shaft and cam to rotate. The cam rotates between two fixed plates, causing the feeding plate to reciprocate linearly within the rectangular groove. When the feeding plate moves to the left, a gap appears between the right side of the feeding plate and the inner wall of one side of the rectangular groove, allowing the raw materials to be discharged. The reciprocating movement of the feeding plate enables the raw materials to be discharged intermittently on both sides of the feeding plate, avoiding accumulation. The feeding plate also drives the moving strip to push the raw materials on the inclined plate to both sides for easy discharge. S4. Cleaning and blowing: When the cam drives the fixed plate to move left and right, the fixed plate squeezes the corresponding air bladder, injects the air in the air bladder into the inclined groove through the air outlet, and blows out the raw material flowing into the inclined groove to avoid accumulation and affect the movement of the feeding plate.

[0016] Beneficial effects: In this invention, the cam rotates between two fixed plates, which can drive the feeding plate to move back and forth in a rectangular groove. As the feeding plate moves back and forth in a linear motion, the raw material can be discharged intermittently on both sides of the feeding plate. Moreover, the movement of the feeding plate can also prevent the raw material from accumulating and clogging. In this invention, the rotating column drives the pin to rotate, and the engagement of the pin with the inclined surface I can drive the arc plate to move downward, thus pulling the filter screen downward. When the pin disengages from the inclined surface I, the filter screen resets under its own toughness, thereby causing the filter screen to vibrate, completing the screening of raw materials on the filter screen, ensuring uniform particle size distribution of raw materials, and avoiding affecting the sealing performance during subsequent injection and packaging. In this invention, the rotating column drives the disc to rotate, and the disc drives the sliding plate to move back and forth in a straight line through the cooperation of the pin and the hexagonal track groove. The sliding plate swings back and forth around the fixed axis through the sliding cooperation of the convex column and the strip groove. Then, the discharge pipe is driven to vibrate through the cooperation of the semi-circular rubber convex block and the ball, which facilitates the uniform discharge of material into the downward material pipe. In this invention, when the sliding plate moves back and forth in a straight line, the rotating plate, which is connected to the sliding joint between the protrusion and the strip groove, swings back and forth around the fixed axis. Therefore, the rotating plate can drive the discharge pipe to vibrate through the contact between the ball and the semi-circular rubber protrusion, so that the raw material entering the discharge pipe can enter the feed pipe along the inclined surface II, so that the raw material can enter the feed pipe evenly, and avoid excessive accumulation of raw material in the feed pipe, which would cause the raw material to accumulate and block the feed pipe, affecting the uniformity of raw material injection into the packaging bag later. In this invention, when the cam drives the fixed plate to move left and right, the fixed plate can squeeze the corresponding air bladder and inject the air in the air bladder into the inclined groove through the air outlet, blowing out the raw material flowing into the inclined groove, avoiding the accumulation of raw material in the inclined groove and affecting the reciprocating movement of the feeding plate; In this invention, the reciprocating moving structure drives the feeding plate to discharge material intermittently, avoiding material accumulation and blockage; the screening structure causes the filter screen to vibrate, ensuring uniform particle size of the raw material and guaranteeing sealing performance; the vibrating structure drives the discharge pipe to vibrate, allowing the raw material to enter the feeding pipe evenly and preventing material accumulation in the feeding pipe; the cavity of the feeding plate cooperates with the airbag to blow out the raw material in the inclined groove; the inclined plate and the push bar prevent material accumulation on the inclined plate; these structures work together to effectively solve the problems of existing feeding devices and improve the working efficiency and packaging quality of the vertical roller packaging machine.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] In one embodiment: Refer to Figures 1-11 A feeding device for a vertical roller packaging machine, relating to the field of packaging machine structure technology, mainly includes a vertical roller packaging machine body 1, a feeding pipe 2, a feeding cylinder 16, and related supporting structures. The feeding pipe 2 is connected to the vertical roller packaging machine body 1 and is used to convey raw materials into the packaging machine; the feeding cylinder 16 is fixed to the top of the vertical roller packaging machine body 1 and is used to store raw materials, and through a series of structures, it realizes the functions of screening and conveying raw materials.

[0021] Reference Figures 3-6An annular baffle 3 is fixed inside the feeding pipe 2, dividing the internal space of the feeding pipe 2. A rectangular groove 4 is provided inside the annular baffle 3, and a feeding plate 5 slides within the rectangular groove 4. Both sides of the feeding plate 5 are provided with inclined grooves 6, which are inclined to allow space between the inner walls of the rectangular groove 4 as the feeding plate 5 moves back and forth. This also allows the raw material entering the inclined grooves 6 to be discharged outwards along the inclined surface of the grooves 6, preventing blockage. The sides of the feeding plate 5 adjacent to the inclined grooves 6 are inclined surfaces. Two inclined panels 13 are fixed to the top of the annular baffle 3, arranged perpendicularly to the inclined grooves 6. These panels both seal the ends of the inclined grooves 6 and allow the raw material to move towards the center, facilitating subsequent discharge. Both inclined panels 13 are slidably provided with levers 14, and both levers 14 are fixedly connected to the feed plate 5. They are used to move the raw materials on the inclined panels 13 when the feed plate 5 moves the levers 14, so as to prevent the raw materials from accumulating on the inclined panels 13.

[0022] Reference Figures 3-5 The feeding tube 2 is equipped with a reciprocating structure for driving the feeding plate 5 to move back and forth. This reciprocating structure includes two horizontal plates 7 fixed inside the feeding tube 2 below the feeding plate 5, with sliding rods 9 sliding through each of the two horizontal plates 7. A fixed plate 8, fixedly connected to the bottom of the feeding plate 5, is fixed to one end of each sliding rod 9. A spring 10 is fixed between the fixed plate 8 and the adjacent horizontal plate 7 via a spring seat. The spring 10 has a spring constant ranging from 50 N / m to 150 N / m and is sleeved on the outer wall of the sliding rod 9. A rotating shaft 11 is rotatably connected inside the feeding tube 2, located between the two fixed plates 8. A cam 12 is fixedly sleeved on the outer wall of the rotating shaft 11. A small motor drives the rotating shaft 11 and the cam 12 to rotate. The cam 12 rotates between the two fixed plates 8, enabling the feeding plate 5 to move reciprocally linearly within the rectangular groove 4.

[0023] Specifically, when the feeding plate 5 moves to the left, a gap appears between the right side of the feeding plate 5 and one inner wall of the rectangular trough 4, facilitating the discharge of raw materials located above. When the feeding plate 5 moves to the right, a gap appears between the left side of the feeding plate 5 and the other inner wall of the rectangular trough 4, allowing for the discharge of raw materials. Therefore, the reciprocating linear movement of the feeding plate 5 allows for intermittent discharge of raw materials on both sides of the feeding plate 5, and the movement of the feeding plate 5 also prevents the accumulation and blockage of raw materials.

[0024] Reference Figure 1 , Figure 7 and Figure 8At least two bases 15 are fixed to the top of the vertical roller packaging machine body 1, and a feeding cylinder 16 is fixed to the top of the base 15. A rotating column 17 is rotatably connected to the top of the vertical roller packaging machine body 1, and the top of the rotating column 17 extends rotatably into the feeding cylinder 16. A filter screen 22 is provided inside the feeding cylinder 16 for screening raw materials and selecting raw materials with uniform particle size.

[0025] Reference Figures 7-9 The discharge cylinder 16 is equipped with a screening structure, which includes a circular ring 20 disposed inside the discharge cylinder 16 and multiple pads 18 fixed to the inner wall of the discharge cylinder 16. The pads 18 are used to support the circular ring 20. Multiple fixing bolts 19 are respectively fixed to the top of the corresponding pads 18. The top of each fixing bolt 19 penetrates the circular ring 20, and the outer wall of each fixing bolt 19 is threaded with a nut block 21 located above the circular ring 20 for fixing the circular ring 20. The filter screen 22 is fixed inside the circular ring 20. Two arc-shaped plates 25 are fixed to the bottom of the filter screen 22. The two arc-shaped plates 25 are located on both sides of the rotating column 17. The side of the two arc-shaped plates 25 that is close to each other is provided with an inclined surface I 26. The outer wall of the rotating column 17 is fixedly fitted with a pin 27.

[0026] During operation, the rotating column 17 drives the pin 27 to rotate. The engagement between the pin 27 and the inclined surface I 26 can drive the arc plate 25 to move downward, thus pulling the filter screen 22 downward. When the pin 27 disengages from the inclined surface I 26, the filter screen 22 resets under its own toughness, thereby causing the filter screen 22 to vibrate, completing the screening of raw materials on the filter screen 22, ensuring uniform particle size distribution of raw materials, and avoiding affecting the sealing performance during subsequent injection and packaging.

[0027] Reference Figure 2 , Figure 7 , Figure 8 and Figure 11 A rotating disk 23 is fixed to the outer wall of the rotating column 17 and rotates on the inner wall of the bottom of the feeding cylinder 16. A conical platform 24 (coated with an oleophobic and hydrophobic coating to reduce material adhesion) is fixed to the top of the rotating disk 23. The conical platform 24 is fixedly sleeved on the outer wall of the rotating column 17 to allow the screened raw material to move outward along the inclined surface of the conical platform 24, facilitating the subsequent discharge of the raw material through the discharge pipe 28. A discharge pipe 28 is fixedly inserted through one side of the feeding cylinder 16, and one end of the discharge pipe 28 is engaged with the rotating disk 23. An inclined surface II 46 is provided inside the discharge pipe 28 to allow the raw material in the discharge pipe 28 to slide down the inclined surface II 46 towards the feeding pipe 2. When the rotating disk 23 rotates, centrifugal force is used to transport the raw material into the discharge pipe 28. The other end of the discharge pipe 28 extends into the feeding pipe 2 for conveying the raw material.

[0028] Reference Figure 1 , Figure 2 , Figure 7 and Figure 10 The top of the vertical roller packaging machine body 1 is equipped with a vibration structure to drive the discharge pipe 28 to vibrate, so that the raw materials inside are evenly discharged into the feed pipe 2. This vibration structure includes a fixed shaft 35 fixed to the top of the vertical roller packaging machine body 1. A rotating plate 39 is rotatably sleeved on the outer wall of the fixed shaft 35. A mounting column 37 located below the discharge pipe 28 is fixed to one side of the top of the rotating plate 39. A ball bearing 38 rotates at the top of the mounting column 37. Multiple semi-circular rubber protrusions 40 are fixed to the bottom of the discharge pipe 28. These semi-circular rubber protrusions 40 are equidistantly arranged around the fixed shaft 35. The ball bearing 38 cooperates with the semi-circular rubber protrusions 40 to drive the discharge pipe 28 to vibrate when the rotating plate 39 rotates.

[0029] Reference Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 10 The vibration structure also includes a sliding plate 29 that slides on the bottom of the discharge cylinder 16. A pin 32 is fixed to the bottom of the side of the fixing bolt 19 near the rotating column 17. A disc 30 located below the sliding plate 29 is fixedly sleeved on the outer wall of the rotating column 17. The top of the disc 30 is provided with a hexagonal track groove 31, which slides with the pin 32 to drive the sliding plate 29 to reciprocate when the disc 30 rotates. A rotating ring 33 is rotatably sleeved on the outer wall of the pin 32 to reduce the friction between the pin 32 and the inner wall of the hexagonal track groove 31. A protrusion 34 is fixed to the top of the side of the sliding plate 29 away from the pin 32. A strip groove 36 that slides with the protrusion 34 is provided inside the rotating plate 39 to drive the rotating plate 39 to reciprocate when the sliding plate 29 moves linearly.

[0030] During operation, the rotating column 17 drives the disc 30 to rotate. The disc 30 drives the sliding plate 29 to move back and forth in a straight line through the cooperation of the pin 32 and the hexagonal track groove 31. The sliding plate 29 drives the rotating plate 39 to swing back and forth around the fixed shaft 35 through the sliding cooperation of the protrusion 34 and the strip groove 36. In turn, the semi-circular rubber protrusion 40 and the ball 38 drive the discharge pipe 28 to vibrate, thereby conveying the raw material in the discharge pipe 28 into the feed pipe 2. This allows the raw material to enter the feed pipe 2 evenly, avoiding excessive accumulation of raw material in the feed pipe 2, which would cause blockage and affect the uniformity of raw material injection into the packaging bag later.

[0031] In another embodiment: Refer to Figure 12The feeding plate 5 has a cavity 44. Air outlets 45 are provided on the inner walls of the two opposite sides of the cavity 44, and these outlets 45 are connected to corresponding inclined slots 6 for blowing out the raw material located in the inclined slots 6. Airbags 41 are fixed to the inner walls of the two adjacent horizontal plates 7. The airbags 41 cooperate with adjacent fixed plates 8 to compress the airbags 41. An air outlet pipe 43 connected to the cavity 44 is fixed to the top of the airbag 41 for injecting gas from the airbag 41 into the cavity 44. An air inlet pipe 42 is fixed to the bottom of the airbag 41. Both the air inlet pipe 42 and the air outlet pipe 43 are equipped with one-way valves.

[0032] Specifically, when the cam 12 drives the fixed plate 8 to move left and right, the fixed plate 8 can compress the corresponding air bladder 41. During the compression process, the one-way valve ensures that air can only be discharged into the cavity 44 through the air outlet pipe 43, and the air in the air bladder 41 is injected into the inclined groove 6 through the air outlet 45, blowing out the raw material flowing into the inclined groove 6 and preventing the raw material from accumulating in the inclined groove 6, which would affect the reciprocating movement of the feeding plate 5. When the fixed plate 8 moves away from the air bladder 41, the air bladder 41 returns to its original position. At this time, the one-way valve allows air to be drawn into the air bladder 41 through the air inlet pipe 42, preparing for the next compression.

[0033] A method for using the feeding device of a vertical roller packaging machine: A circular ring 20 is placed inside the feeding cylinder 16, supported by a pad 18, and a fixing bolt 19 passes through the circular ring 20. The nut block 21 is tightened, and the engagement of the nut block 21 and the fixing bolt 19 secures the circular ring 20. Next, raw materials are fed onto the filter screen 22. A motor drives a rotating column 17 to rotate, which in turn drives a pin 27 to rotate. The engagement of the pin 27 with the inclined plane I 26 causes the arc plate 25 to move downwards, thus pulling the filter screen 22 downwards. When the pin 27 disengages from the inclined plane I 26, the filter screen 22 resets under its own resilience, causing the filter screen 22 to vibrate, thus completing the screening of the raw materials on the filter screen 22 and ensuring the particle size of the raw materials. The material is evenly distributed to avoid affecting the sealing performance during later injection and packaging. The screened raw material falls onto the conical platform 24 and flows towards the outer circumference under the action of the inclined surface of the conical platform 24. As the rotating column 17 drives the rotating disk 23 and the conical platform 24 to rotate, the raw material approaches the inner wall of the discharge cylinder 16 under the action of centrifugal force. Therefore, during the rotation, the raw material is discharged into the discharge pipe 2 through the discharge pipe 28. The raw material is injected into the body 1 of the vertical roller packaging machine during the later packaging process. At the same time, the rotating column 17 drives the disc 30 to rotate. The disc 30 drives the sliding plate 29 to move back and forth linearly through the cooperation of the pin 32 and the hexagonal track groove 31. The sliding plate 29 moves back and forth linearly through the sliding cooperation of the protrusion 34 and the strip groove 36. The rotating plate 39 is fixed on the fixed shaft 35. The axis reciprocates, so the rotating plate 39, through the contact between the ball bearing 38 and the semi-circular rubber protrusion 40, can drive the discharge pipe 28 to vibrate. This allows the raw material entering the discharge pipe 28 to enter the feed pipe 2 along the inclined surface II 46, ensuring that the raw material enters the feed pipe 2 evenly and preventing excessive accumulation of raw material in the feed pipe 2, which would cause blockage and affect the uniformity of raw material injection into the packaging bags later. When it is necessary to inject raw material into the packaging bags processed by the vertical roller packaging machine body 1, the rotating shaft 11 and cam 12 are driven to rotate by a small motor. The cam 12 rotates between the two fixed plates 8, which can drive the feed plate 5 to reciprocate linearly within the rectangular groove 4. When the feed plate 5 moves to the left, the feed plate 5... A gap appears between the right side and the inner wall of one side of the rectangular groove 4, which facilitates the discharge of raw materials located above. Therefore, as the feeding plate 5 moves back and forth in a straight line, the raw materials can be discharged intermittently on both sides of the feeding plate 5. The movement of the feeding plate 5 can also prevent the raw materials from accumulating and blocking. In addition, the feeding plate 5 also drives the push bar 14 to move synchronously, pushing the raw materials located on the inclined plate 13 to both sides, so that the raw materials can be discharged through the movement of the feeding plate 5. When the cam 12 drives the fixed plate 8 to move left and right, the fixed plate 8 can squeeze the corresponding air bag 41 and inject the air in the air bag 41 into the inclined groove 6 through the air outlet 45, blowing out the raw materials flowing into the inclined groove 6, preventing the raw materials from accumulating in the inclined groove 6 and affecting the reciprocating movement of the feeding plate 5.

In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

10. A method of using a feeding device for a vertical roller packaging machine, applied to the feeding device of the vertical roller packaging machine as described in claim 9, characterized in that, Includes the following steps: S1. Place the ring (20) inside the feeding cylinder (16), support it with the pad (18), and fix the ring (20) with the fixing bolt (19) and nut block (21); feed the raw material onto the filter screen (22); start the motor to drive the rotating column (17) to rotate, the rotating column (17) drives the pin (27) to rotate, the pin (27) cooperates with the inclined plane I (26) to drive the arc plate (25) to move down, thereby pulling the filter screen (22) downward. When the pin (27) disengages from the inclined plane I (26), the filter screen (22) resets under its own toughness and vibrates, thus completing the raw material screening; S2. The screened raw material falls onto the conical platform (24) and flows towards the outer circumference under the action of the inclined surface of the conical platform (24). The rotating column (17) drives the rotating disk (23) and the conical platform (24) to rotate. Under the action of centrifugal force, the raw material approaches the inner wall of the discharge cylinder (16) and is discharged to the discharge pipe (2) through the discharge pipe (28). At the same time, the rotating column (17) drives the disc (30) to rotate. The disc (30) drives the sliding plate (29) to move back and forth in a straight line through the pin (32) and the hexagonal track groove (31). The sliding plate (29) drives the rotating plate (39) to swing back and forth around the fixed shaft (35) through the sliding cooperation of the convex column (34) and the strip groove (36). The rotating plate (39) drives the discharge pipe (28) to vibrate through the contact of the ball (38) and the semi-circular rubber protrusion (40), so that the raw material enters the discharge pipe (2) evenly along the inclined surface II (46). S3. When injecting raw materials into the packaging bag, a small motor drives the rotating shaft (11) and cam (12) to rotate. The cam (12) rotates between two fixed plates (8), causing the feeding plate (5) to move back and forth in a straight line within the rectangular groove (4). When the feeding plate (5) moves to the left, a gap appears between the right side of the feeding plate (5) and the inner wall of one side of the rectangular groove (4), allowing the raw materials to be discharged. The reciprocating movement of the feeding plate (5) enables the raw materials to be discharged intermittently on both sides of the feeding plate (5), avoiding accumulation. The feeding plate (5) also drives the push bar (14) to move, pushing the raw materials on the inclined plate (13) to both sides. S4. When the cam (12) drives the fixed plate (8) to move left and right, the fixed plate (8) squeezes the corresponding air bag (41), and injects the air in the air bag (41) into the inclined groove (6) through the air outlet (45), and blows out the raw material flowing into the inclined groove (6).
