Description

Technical Field

[0001] This utility model relates to the technical field of bagging machine equipment, specifically a three-cylinder circulating bagging device. Background Technology

[0002] This design addresses the main process factors contributing to low bagging efficiency. Currently, due to limitations in the rigidity of the core shaft material inside the agitator, the agitator blades lack sufficient rigidity at high speeds, leading to a swirl effect. The longer the agitator, the greater the deflection of the core shaft and agitator blades, increasing the likelihood of this swirl effect. Therefore, the current agitator length is generally no longer than 380mm. This results in a problem where the bag-supporting claws used in the current bag-insertion method cannot detach from the agitator after the mushroom bag is placed inside. The bag can only be removed from the agitator after the substrate is filled and the bag retracts, allowing the agitator to proceed to the next step. This waiting time affects the overall bagging efficiency.

[0003] Currently, the bagging mechanisms of mushroom bagging machines have two-way operation along the Z-axis and X-axis. For example, Chinese patent CN209275004U discloses a bagging device for an edible mushroom bagging machine, and Chinese patent CN222030791U discloses a bag feeding device for an edible mushroom bagging machine. There are also two-way operation along the Z-axis and Y-axis, such as Chinese patent CN221104326U, which discloses a fully automatic mushroom bagging device with a rocker arm movement. All three methods suffer from the problem of the bag-supporting mechanism holding the mushroom bag while waiting for the bag-holding mechanism to dispense the material. Therefore, a three-cylinder circulating bagging device is needed to solve these technical problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 1-10 This utility model provides a three-cylinder circulating bagging device, including: a hopper 1, a frame 2, a filling agitator 3, a bag supporting device 4, an auxiliary bagging cylinder 5, and a circulating bagging cylinder 6. The hopper 1 is fixedly installed on the outer side of the frame 2, and the filling agitator 3 is threadedly connected to the bottom of the hopper 1. The auxiliary bagging cylinder 5 is also provided on the inner side of the frame 2 near the hopper 1. A hook stop 30 is provided on the bottom of the frame 2 near the auxiliary bagging cylinder 5. An outer frame 7 is fixedly connected to the outer side of the frame 2. The bag supporting device 4 is slidably connected to the outer frame 7. A hook stop 29 is provided on the inner side of the outer frame 7 near the circulating bagging cylinder 6. A traveling track 16 is also provided inside the frame 2, and the traveling track 16 is slidably connected to the circulating bagging cylinder 6.

[0033] Since the auxiliary bagging cylinder 5 is not located in the filling chamber, the length of the auxiliary bagging cylinder 5 can be unrestricted during machine layout. This allows the bag-supporting device 4 to have enough space to put the mushroom bag on the auxiliary bagging cylinder 5 before continuing to move forward to detach the mushroom bag and proceed to the next step of bag removal.

[0034] Preferably, the auxiliary bagging cylinder 5 includes an octagonal bag-supporting mechanism 8 and a ventilation cylinder 9, wherein the octagonal bag-supporting mechanism 8 and the ventilation cylinder 9 are slidably connected.

[0035] Preferably, the octagonal bag-supporting mechanism 8 includes a rotating base 10, a sliding sleeve 11, a return spring 12, and a bag-supporting plate 13. The air cylinder 9 includes a threaded air pipe 14 and an empty bucket 15. One end of the threaded air pipe 14 is connected to an air pump, and the other end passes through the sliding sleeve 11 and the return spring 12 in sequence and is slidably connected to the empty bucket 15. The bag-supporting plate 13 is hinged on the sliding sleeve 11, and the bag-supporting plate 13 is hinged to the rotating base 10.

[0036] The octagonal bag-supporting mechanism 8 ensures that no matter which of the eight bag-supporting plates 13 rotates inward or outward under force, the remaining bag-supporting plates 13 will rotate inward or outward simultaneously. This ensures that when the circulating bag-covering cylinder 6 covers the mushroom bag onto the octagonal bag-supporting mechanism 8, the mushroom bag opens into a regular octagon, and the center of the octagon is located at the exact center of the auxiliary bag-covering cylinder 5, thus positioning the mushroom bag and ensuring the accuracy of bag removal.

[0037] One end of the threaded vent pipe 14 is connected to a throttling connector to high-pressure gas, and the high-pressure gas is controlled by an electromagnetic pneumatic valve, while the throttling valve controls the gas flow rate. During operation, the bag-supporting claws of the bag-supporting device 4 support the mushroom bag and move it from the bottom of the auxiliary bag-covering cylinder 5 to the octagonal bag-supporting mechanism 8. The bag-supporting claws of the bag-supporting device 4 touch and squeeze six of the eight bag-supporting plates 13 on the left and right sides. The eight bag-supporting plates 13 simultaneously rotate inward, pushing against the sliding sleeve 11 and compressing the return spring 12 to move backward. The bag-supporting claws of the bag-supporting device 4 continue to carry the mushroom bag forward until the bottom of the mushroom bag can cover the bottom of the auxiliary bag-covering cylinder 5. At this time, the mushroom bag stops moving forward, while the bag-supporting claws of the bag-supporting device 4 continue to move forward. During the forward movement, the bag-supporting claws of the bag-supporting device 4 disengage from the mushroom bag until they disengage from the auxiliary bag-covering cylinder 5. At this time, the bag-supporting plates 13 are released, and the sliding sleeve 11 moves forward under the action of the return spring 12, thereby driving the eight bag-supporting plates 13 to rotate outward simultaneously to support the mushroom bag. The bag-supporting device 4 retracts, completing the bag-covering process of the bag-supporting device 4 on the auxiliary bag-covering cylinder 5.

[0038] When the circulating bagging cylinder 6 removes the bag, its eight hooking plates 22 are positioned on the same side of the eight supporting plates 13. After hooking the bag, it moves backward, and at the same time, the ventilation solenoid valve opens, allowing air to rush out from the bottom of the auxiliary bagging cylinder 5, filling the bag with air and separating the bag from the ventilation cylinder 9 of the auxiliary bagging cylinder 5 with air. This prevents the bag from sticking to the auxiliary bagging cylinder 5 due to static electricity or moisture, and prevents the bag from turning outward during the process of exiting the auxiliary bagging cylinder 5. After the circulating bagging cylinder 6 completely exits the auxiliary bagging cylinder 5, the solenoid valve shuts off the air supply, completing the bag removal process of the circulating bagging cylinder 6 from the auxiliary bagging cylinder 5.

[0039] Preferably, the circulating bagging cylinder 6 includes a slider, a frame, a walking motor 17, a rotary control motor 18, a base 19, a bagging structure, and a closing track 35. The slider is slidably connected to the walking track 16. The output end of the walking motor 17 is electrically connected to the input end of the slider. The frame is fixedly connected to the slider. The walking motor 17, the rotary control motor 18, and the closing track 35 are all fixedly connected to the frame. The output end of the rotary control motor 18 is rotatably connected to the base 19 through a rotating shaft. The three bagging structures are circumferentially fixed to the base 19. The closing track 35 has a notch and is slidably connected to the bagging structure.

[0040] Preferably, the packaging structure includes a bag hooking mechanism 20, a spring actuation mechanism, and a flapping and closing tube 21. The flapping and closing tube 21 is provided with a spring actuation mechanism on its outer side, and the spring actuation mechanism is fixedly connected to the bag hooking mechanism 20.

[0041] Each opening and closing cylinder 21 and a bag hooking mechanism 20 are located at the same workstation, working together to complete the processes of bag removal, bagging, filling, and bag dropping for a mushroom bag. The three bagging structures are respectively aligned with the auxiliary bagging cylinder 5, the filling agitator 3, and the bag dropping position. When the three sets are rotated clockwise in the right view, they complete the process cycle of bag removal → filling → bag dropping in sequence, and then continue to cycle.

[0042] Preferably, the bag hooking mechanism 20 includes bag hook pieces 22, bag hook retainers 23, connecting pieces 24, and a ring frame 36. The bag hook retainer 23 is ring-shaped, and a plurality of bag hook pieces 22 are circumferentially distributed on the inner side of the bag hook retainer 23. The plurality of bag hook pieces 22 are hinged to the bag hook retainer 23 and the connecting pieces 24. The connecting pieces 24 are hinged to the ring frame 36. The bag hook retainer 23 and the ring frame 36 are both fixedly connected to a spring actuation mechanism.

[0043] Preferably, the spring actuator includes a sliding base 26, a retaining spring 27, a contact rod 28, a sliding bearing seat 34, and a sliding connecting rod 25. The sliding bearing seat 34 is fixedly connected to the outer side of the opening and closing cylinder 21. The sliding connecting rod 25 is slidably connected to the sliding bearing seat 34. The sliding connecting rod 25 is fixedly connected to the sliding base 26 and the ring frame 36. A sliding groove is provided on the sliding base 26, and a rotating shaft is provided in the sliding groove. The rotating shaft is fixedly connected to the opening and closing cylinder 21. The contact rod 28 is hinged to the rotating shaft. The two ends of the retaining spring 27 are respectively fixed to the sliding base 26 and the contact rod 28.

[0044] Since the base 19, the hooking mechanism 20, and the opening and closing clamping cylinder 21 all need to rotate to a certain extent when the circulating bagging cylinder 6 is working, and the three hooking mechanisms 20 need to be controlled separately, the cylinder and motor cannot achieve the required functions. Therefore, the hooking plate 22 is used to ensure that the bag is always hooked without loosening when hooking the bag by the force provided by a spring-driven mechanism. In each reciprocating motion of the circulating bagging cylinder 6, the contact rod 28 on the spring-driven mechanism will touch different blocks (open hook block 29 and closed hook block 30), thereby enabling each hooking mechanism 20 to maintain the corresponding state (hooked state or open state) in different positions.

[0045] Preferably, the opening and closing cylinder 21 includes a movable half-cylinder, a fixed half-cylinder, a closing cylinder bearing 31, a torsion spring 32, and a hinge 33. The movable half-cylinder and the fixed half-cylinder are hinged together by the hinge 33. The closing cylinder bearing 31 and the torsion spring 32 are both mounted on the movable half-cylinder. The spring actuation mechanism is mounted on the fixed half-cylinder. The closing cylinder bearing 31 is slidably connected to the closing cylinder track 35.

[0046] Because the torsion spring extends to two pressure points, one fixed to the fixed half-cylinder and the other attached to the movable half-cylinder, it can provide a continuous opening force to the movable half-cylinder.

[0047] When the circulating bag sleeve 6 rotates, the closing bearing 31 travels within the closing track 35 and presses the movable half-sleeve together. One of the three bagging structures will always be in the bag-dropping position. At this position, because there is a notch on the closing track 35, the closing bearing 31 will be released from its restraint, and the movable half-sleeve will open under the action of the torsion spring 32. When it rotates again, the closing bearing 31 will return to the closing track 35 and close the movable half-sleeve.

[0048] Preferably, the opening hook stop 29 and the closing hook stop 30 abut against the touch rod 28.

[0049] When the circulating bagging cylinder 6 moves forward from the bag dropping position to the bag hooking position, the contact rod 28 will collide with the hooking block 30. The contact rod 28 will first tilt, and under the action of the tension spring 27, it will drive the sliding base 26 to shift towards the base 19, which will then drive the sliding connecting rod 25 to move towards the base 19. Finally, the connecting piece 24 on the ring frame 36 will pull the eight bag hook pieces 22, which will rotate inward synchronously on the bag hooking holder 23, so that the bag hook pieces 22 are in the bag hooking state and hook the mushroom bag.

[0050] Furthermore, under the tension of the tension spring 27, the eight hook-shaped bag pieces 22 always exert an opening force on the mushroom bag to hold it in place.

[0051] When the circulating bagging cylinder 6 moves forward from the filling position to the bag dropping position, the contact rod 28 will collide with the hook opening block 29. The contact rod 28 will first tilt, and under the action of the tension spring 27, it will drive the sliding base 26 to shift in the opposite direction of the base 19, which will then drive the sliding connecting rod 25 to move in the opposite direction of the base 19. Finally, the connecting piece 24 on the ring frame 36 will pull the eight hook bag pieces 22, which will rotate outward synchronously on the hook bag retainer 23, so that the hook bag pieces 22 are in the open state and the mushroom bag is released.

[0052] When the circulating bag sleeve 6 rotates under the drive of the rotary motor, the contact rod 28 will also touch the hook stop 29. Since it is a one-way hinge and will rotate from back to front, the spring actuation mechanism will not be triggered here.

[0053] Preferably, the circulating bag sleeve 6 corresponds to the packing agitator 3 and the auxiliary bag sleeve 5.

[0054] The specific method of using this utility model is as follows:

[0055] First, the bag-supporting device 4 places the mushroom bag onto the auxiliary bag-supporting cylinder 5. The octagonal bag-supporting mechanism 8 on the auxiliary bag-supporting cylinder 5 supports the mushroom bag, keeping it open and fixed on the auxiliary bag-supporting cylinder 5. Second, after placing the mushroom bag onto the auxiliary bag-supporting cylinder 5, the circulating bag-supporting cylinder 6 removes the bag from the auxiliary bag-supporting cylinder 5. Third, after removing the bag, the circulating bag-supporting cylinder 6 rotates to prepare for filling. After filling, the circulating bag-supporting cylinder 6 rotates again to prepare for dropping the bag. After dropping the bag, the circulating bag-supporting cylinder 6 rotates again. This process is repeated, with each bag-supporting cylinder completing the three processes of bag removal, filling, and dropping in sequence. This cycle continues until the bag-supporting machine completes its bag-supporting work.

[0056] The specific operation of the bag-supporting device 4 in bagging the auxiliary bagging cylinder 5 is as follows: The bag-supporting claws of the bag-supporting device 4 support the mushroom bag and move it from the bottom of the auxiliary bagging cylinder 5 towards the octagonal bag-supporting mechanism 8. The bag-supporting claws of the bag-supporting device 4 touch and squeeze the six pieces on the left and right sides of the eight bag-supporting pieces 13. At the same time, the eight bag-supporting pieces 13 rotate inward and push against the sliding sleeve 11 to compress the return spring 12 and move backward. The bag-supporting claws of the bag-supporting device 4 continue to carry the mushroom bag forward until the bottom of the mushroom bag can cover the auxiliary bagging cylinder 5. At the bottom, the mushroom bag stops moving forward, while the bag-supporting claw of the bag-supporting device 4 continues to move forward. During the forward movement, the bag-supporting claw of the bag-supporting device 4 disengages from the mushroom bag until it disengages from the auxiliary bag-covering cylinder 5. At this point, the bag-supporting piece 13 is released, and the sliding sleeve 11 moves forward under the action of the return spring 12, thereby driving the eight bag-supporting pieces 13 to rotate outward simultaneously to support the mushroom bag. The bag-supporting device 4 retracts, completing the bag-covering process of the bag-supporting device 4 on the auxiliary bag-covering cylinder 5.

[0057] The specific operation of the circulating bagging cylinder 6 in completing the three processes of bag removal, filling, and bag dropping is as follows: After the mushroom bag is placed on the auxiliary bagging cylinder 5, the circulating bagging cylinder 6 moves forward from the bag dropping position to the filling hook position. The first bagging structure of the three bagging cylinders on the circulating bagging cylinder 6 is placed on the auxiliary bagging cylinder 5. The contact rod 28 on the first bagging structure will collide with the hook stop block 30. The contact rod 28 will first tilt, and under the action of the tension spring 27, it will drive the sliding base 26 towards the base 19. The directional shift causes the sliding connecting rod 25 to move towards the base 19, ultimately causing the connecting piece 24 on the ring frame 36 to pull the eight hooking pieces 22, which then rotate synchronously inward on the hooking bag retainer 23, so that the hooking pieces 22 are in the hooking bag state and hook the mushroom bag. The hooking pieces 22 will remain in the hooking bag state. At the same time, the second bagging structure on the circulating bagging cylinder 6 fills the filling cage 3. The third bagging structure on the circulating bagging cylinder 6 opens its two halves under the action of the torsion spring for bag dropping. After the filling is finished, the circulating bagging cylinder 6 begins to retreat under the reaction force of the walking motor 17. At this time, the first bagging structure, driven by the walking motor 17, hooks the mushroom bag on the auxiliary bagging cylinder 5 with the hooking piece 22 and begins to retreat to the bag dropping position. The air pipe on the auxiliary bagging cylinder 5 stops supplying air, and at the same time, the threaded air pipe 14 connected to the auxiliary bagging cylinder 5 starts supplying air, so that the inside of the mushroom bag that is being released is filled with gas. When the first bagging structure retracts to the bag dropping position, the contact rod 28 on the second bagging structure will collide with the hook opening block 29. The contact rod 28 will first tilt, and under the action of the tension spring 27, it will drive the sliding base 26 to shift in the opposite direction of the base 19, which will then drive the sliding connecting rod 25 to move in the opposite direction of the base 19. Finally, the connecting piece 24 on the ring frame 36 will pull the eight hook bag pieces 22, which will rotate outward synchronously on the hook bag retainer 23, so that the hook bag pieces 22 are in the open state and the mushroom bag is released.

[0058] The above states represent the first state: the first packaging structure removes the bag, the second packaging structure fills the bag, and the third packaging structure drops the bag.

[0059] Then, the circulating bagging cylinder 6 rotates 120 degrees under the drive of the rotary motor, causing the first bagging structure, which is in the hooked bag state, to rotate to the position of the second bagging structure before it, aligning with the seasoning mixing cage to prepare for filling; the second bagging structure, which contains the filled mushroom bags, rotates to the bag dropping position of the third bagging structure before it. At this time, because the closing bearing 31 on the second bagging structure is released from the restraint of the closing track 35, the movable half-cylinder opens under the action of the torsion spring, and the mushroom bag falls at the bag dropping position; the third bagging structure after the bag drops rotates to the position of the first bagging structure before it. At this time, because the closing bearing 31 on the third bagging structure will re-enter the restraint track, the movable half-cylinder will close, and the third bagging structure will align with the auxiliary bagging cylinder 5, ready to remove the bag.

[0060] After the second state (first bagging structure filling, second bagging structure dropping, third bagging structure removing) is completed, the circulating bagging cylinder 6 rotates 120 degrees under the drive of the rotary motor, adjusting the state to the third state (first bagging structure dropping, second bagging structure removing, third bagging filling). After the third state is completed, the circulating bagging cylinder 6 rotates another 120 degrees under the drive of the rotary motor, adjusting the state to the first state (first bagging structure removing, second bagging structure filling, third bagging structure dropping). This cycle repeats continuously, with each bagging cylinder sequentially completing the three processes of bag removal, filling, and dropping, and then repeating the cycle again to complete the bagging operation of the bagging machine.
