Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and particularly to a suspended bagged flour loading and conveying device. Background Art

[0002] In the field of grain processing, the production and transportation of bagged flour exhibit significant characteristics of high-level production and low-level loading. The packaging production line of grain processing plants is usually erected on a high platform. After the finished flour is encapsulated by an automatic packaging machine, it needs to fall from a high position to the truck carriage on the ground floor through a conveying device. In this process, as a key hub connecting the production end and the transportation end, the performance of the conveying device directly affects the loading efficiency, material loss, and operation safety.

[0003] Traditional loading equipment mostly uses rigid chutes with fixed angles, which have significant defects. The landing position of traditional fixed chutes is fixed, and it is necessary to rely on the lateral translation of the truck to adjust the material receiving position, or manually follow and carry on the truck. However, it is easy for the truck to move forward and backward, but it requires multiple direction adjustments for translation, and the operation is cumbersome and time-consuming. In a narrow space, it is difficult for the truck to achieve flexible translation, resulting in a large deviation in the landing point of the flour bag, and manual secondary handling and adjustment are required, with low loading efficiency and high labor intensity. Summary of the Invention

[0004] The purpose of the present invention is to provide a suspended bagged flour loading and conveying device to solve the problems of low loading efficiency and high labor intensity of traditional loading equipment that mostly uses rigid chutes with fixed angles.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A suspended bagged flour loading and conveying device includes a receiving tray. A blanking through hole for bagged flour to pass through is provided in the middle of the receiving tray. The bottom end of the receiving tray is rotatably connected to a rotating ring. The bottom end of the rotating ring is fixedly connected to a support rod. The bottom end of the support rod is fixedly connected to a support plate. A feeding chute is rotatably connected to the surface of the support plate. A traction rope for pulling the feeding chute is installed on the surface of the support rod.

[0006] Preferably, an outer gear ring is fixedly sleeved on the outer circle of the rotating ring. A transmission gear is rotatably connected to the bottom end of the receiving tray. The transmission gear is meshed with the rotating ring. A first motor is installed at the bottom of the receiving tray, and its output shaft is coaxially and fixedly connected to the transmission gear.

[0007] Preferably, an adjustable slider that can slide horizontally is connected to the surface of the support rod. A fixed pulley is fixedly connected to the bottom end of the adjustable slider. One end of the traction rope is rotatably connected to the feeding chute, and the other end is fixedly connected to the support rod after passing around the outer peripheral groove of the fixed pulley.

[0008] Preferably, a threaded rod is rotatably connected to the surface of the support rod, a threaded hole matching the threaded rod is formed in the surface of the adjustment slider, and a second motor for driving the threaded rod to rotate is installed on the surface of the support rod.

[0009] Preferably, a limiting cover is fixedly connected to the inner wall of the feeding chute, a resetable buffer plate is rotatably connected to the bottom end of the limiting cover, and the limiting cover is located directly below the through hole of the material receiving tray.

[0010] Preferably, a torsion spring is fixedly connected between the limiting cover and the buffer plate.

[0011] Preferably, a resetable positioning plate is rotatably connected to the surface of the support plate, the positioning plate is located at the lower end of the feeding chute, and a locking bolt for locking the positioning plate is installed inside the support plate.

[0012] Preferably, a spline shaft is fixedly connected to the side surface of the positioning plate, the spline shaft is rotatably connected to the support plate, and the locking bolt is locked to the positioning plate by being inserted between two spline teeth at the bottom end of the spline shaft and pressing against the tooth surface.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The loading position can be adjusted to adapt to complex loading scenarios. Through the rotating feeding chute, the orientation of the end of the chute can be flexibly adjusted in the horizontal plane, breaking through the limitation of the truck's translation. Without relying on the truck's lateral movement, the landing position of the bagged flour in the width direction of the truck can be controlled, solving the problem of landing deviation caused by the inability of the traditional fixed chute to translate the truck, and improving the loading efficiency and space utilization rate. 2. The angle of the feeding chute can be adjusted steplessly to match different loading stages. At the initial stage of loading: the truck is relatively empty, the chute angle is adjusted larger to make the sliding bottom closer to the bottom of the truck carriage, avoiding the impact of the flour bag on the carriage due to too large a drop. At the later stage of loading: the flour has been stacked to a relatively high position, the chute angle is adjusted smaller to adapt to the height of the flour stack, realizing the adaptive matching of different loading stages and taking into account both efficiency and stacking quality. 3. The positioning plate and the locking bolt build a double safety guarantee. During normal operation, the positioning plate automatically fits as the chute angle is adjusted, assisting in supporting the load of the chute, dispersing the force on the traction rope, and reducing the fatigue loss of the traction rope. When the traction rope breaks or becomes slack, the locking bolt quickly locks the positioning plate to prevent the chute from falling out of control, avoiding safety accidents and equipment damage.

Detailed implementation manners

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1 to 9 , the present invention provides a technical solution.

[0018] A suspension type bagged flour loading and conveying device, including a material receiving tray 2. A blanking through hole for bagged flour to pass through is provided in the middle of the material receiving tray 2. The bottom end of the material receiving tray 2 is rotatably connected with a rotating ring 4. The bottom end of the rotating ring 4 is fixedly connected with a support rod 9. The bottom end of the support rod 9 is fixedly connected with a support plate 20. A feeding chute 16 is rotatably connected to the surface of the support plate 20. A traction rope 14 for pulling the feeding chute 16 is installed on the surface of the support rod 9. By driving the rotation of the rotating ring 4, the support rod 9, the support plate 20 and the feeding chute 16 can be driven to rotate synchronously, flexibly adjusting the orientation of the end of the feeding chute 16. For the scenario where the truck cannot be horizontally translated, the landing position of the bagged flour can be controlled in the width direction of the truck, solving the position deviation problem during traditional fixed chute loading, significantly improving the loading efficiency. The inclination angle of the feeding chute 16 can be dynamically adjusted, and the chute inclination angle can be adjusted in real time, so that the height when the bagged flour slides down from the end of the chute can avoid the powder being scattered due to too large a drop and prevent insufficient height from affecting the stacking neatness, realizing the adaptive matching in different loading stages.

[0019] Embodiment of the rotational connection relationship of the rotating ring 4: The bottom end of the material receiving tray 2 is fixedly connected with a T-shaped shaft 7. The top end of the rotating ring 4 is provided with a circular T-shaped chute 8 for the T-shaped shaft 7 to match. The horizontal flange of the T-shaped shaft 7 is engaged in the circular T-shaped chute 8, and the vertical shaft body penetrates the vertical guiding hole of the chute, so that the rotating ring 4 can freely rotate around the central axis of the material receiving tray 2. At the same time, the axial detachment is restricted by the horizontal flange, ensuring the structural stability during the rotation process.

[0020] Embodiment of the operation of controlling the rotation of the rotating ring 4: An external gear ring is fixedly sleeved on the outer ring of the rotating ring 4. The bottom end of the material receiving tray 2 is rotatably connected with a transmission gear 5. The transmission gear 5 is meshed with the rotating ring 4. A first motor 6 is installed at the bottom of the material receiving tray 2, and its output shaft is fixedly connected coaxially with the transmission gear 5. When the first motor 6 is started, the motor torque is transmitted to the external gear ring of the rotating ring 4 through the transmission gear 5, driving the rotating ring 4 to rotate uniformly around the central axis, realizing the orientation adjustment of the feeding chute 16.

[0021] Furthermore, a reinforcing ring 3 is fixedly connected to the bottom end of the material receiving tray 2. The rotating ring 4 is rotatably connected coaxially with the reinforcing ring 3. The setting of the reinforcing ring 3 can disperse the radial load of the rotating ring 4 to the overall structure of the material receiving tray 2, ensuring the stability when the feeding chute 16 rotates and positions.

[0022] Embodiment of the rotational connection relationship of the feeding chute 16: A rotating shaft is fixedly connected to the surface of the support plate 20. The rotating shaft movably penetrates the surface of the feeding chute 16, so that the feeding chute 16 rotates around the axis of the rotating shaft. The setting position of the rotating shaft is close to the end of the highest point of the feeding chute 16, forming an eccentric pivot center. When the lower end of the feeding chute 16 is pulled by the traction rope 14, the chute rotates around the rotating shaft.

[0023] Embodiment of controlling the rotation operation of the feeding chute 16: An adjustable slider 10 that can slide horizontally is connected to the surface of the support rod 9. A fixed pulley 13 is fixedly connected to the bottom end of the adjustable slider 10. One end of the traction rope 14 is rotatably connected to the feeding chute 16, and the other end is fixedly connected to the support rod 9 after passing around the outer peripheral groove of the fixed pulley 13. When the adjustable slider 10 is driven to slide horizontally, the fixed pulley 13 moves synchronously, changing the effective rope lengths of the traction ropes 14 on both sides of the fixed pulley 13. If the adjustable slider 10 moves to the left, the length of the traction rope 14 on the right side of the fixed pulley 13 becomes shorter, the inclination angle of the feeding chute 16 decreases, and the height of the end rises. On the contrary, if the adjustable slider 10 moves to the right, the length of the traction rope 14 on the right side of the fixed pulley 13 becomes longer, the inclination angle of the feeding chute 16 increases, and the height of the end drops. By continuously sliding the adjustable slider 10, stepless adjustment of the inclination angle of the feeding chute 16 within the range of 0° to 45° can be achieved.

[0024] Embodiment of the sliding connection relationship of the adjustable slider 10: T-shaped plates are fixedly connected to both sides of the support rod 9. T-shaped grooves for the T-shaped plates to slide are formed by matching on the inner surface of the adjustable slider 10. By the T-shaped plates being located in the T-shaped grooves, it has the functions of bearing the guiding load and restricting the rotational freedom, providing a stable motion reference for subsequent angle adjustment.

[0025] Embodiment of controlling the sliding operation of the adjustable slider 10: A threaded rod 11 is rotatably connected to the surface of the support rod 9. A threaded hole matching the threaded rod 11 is formed on the surface of the adjustable slider 10, forming a lead screw-nut transmission pair. A second motor 12 for driving the threaded rod 11 to rotate is installed on the surface of the support rod 9. When the second motor 12 is energized and rotates, the torque is transmitted to the threaded rod 11, and the adjustable slider 10 moves linearly along the axial direction of the threaded rod 11. By controlling the forward and reverse rotation of the second motor 12, reciprocating sliding adjustment of the adjustable slider 10 within the range of the support rod 9 can be achieved.

[0026] Embodiment of the rotational connection relationship of the traction rope 14: A connecting shaft block 15 is fixedly connected to the end of the traction rope 14. The connecting shaft block 15 is rotatably connected to the feeding chute 16. The installation position of the connecting shaft block 15 is near the end of the lower end of the feeding chute 16, forming an eccentric pulling point to ensure that the pulling force line of the traction rope 14 deviates from the center of gravity of the chute, generating an effective rotational torque.

[0027] Furthermore, a limiting cover 17 is fixedly connected to the inner wall of the feeding chute 16. A resetable buffer plate 18 is rotatably connected to the bottom end of the limiting cover 17. The limiting cover 17 is located directly below the through hole of the receiving tray 2 and at the end of the feeding chute 16 close to the highest point. When the bagged flour freely falls from the through hole of the receiving tray 2, it drops onto the buffer plate 18. The gravity of the flour overcomes the initial torque of the buffer plate 18, driving the buffer plate 18 to rotate downward around the axis. During this process, the torsional damping effect of the buffer plate 18 absorbs the impact energy of the flour, reducing the impact load on the feeding chute 16. When the flour slides into the feeding chute 16 along the inclined buffer plate 18, the load on the buffer plate 18 disappears, and the buffer plate 18 resets to the horizontal state, preparing for the next material drop, achieving buffering of the bagged flour and avoiding problems such as damage to the flour bag or spillage of powder caused by direct impact in traditional rigid chutes.

[0028] Embodiment of the resetable connection relationship of the buffer plate 18: A torsion spring 19 is fixedly connected between the limiting cover 17 and the buffer plate 18. In the initial state, the torsion spring 19 maintains a pre-torsion angle of 5°, keeping the buffer plate 18 in a horizontal posture. When the bagged flour impacts the buffer plate 18, the buffer plate 18 rotates downward around the axis, driving the torsion spring 19 to further twist. The torsion spring 19 undergoes elastic deformation and then stores elastic potential energy. When the flour slides off the buffer plate 18, the elastic potential energy of the torsion spring 19 is converted into a reset torque, driving the buffer plate 18 to rotate reversely around the axis. This torque overcomes the moment of inertia and frictional resistance of the buffer plate 18 itself, causing the buffer plate 18 to reset to the initial horizontal position, completing a buffering cycle.

[0029] Furthermore, a resetable positioning plate 25 is rotatably connected to the surface of the support plate 20. The positioning plate 25 is located at the lower end of the feeding chute 16 and has a tendency to reset to the horizontal state. By setting the positioning plate 25 to be resetable, when the feeding chute 16 adjusts the angle downward, it will press the positioning plate 25 to rotate accordingly. When the feeding chute 16 adjusts the angle upward, the positioning plate 25 will automatically reset under the action of elastic force, always keeping close to the lower end of the feeding chute 16. A locking pin 23 for locking the positioning plate 25 is installed inside the support plate 20. After the feeding chute 16 is adjusted to the target angle, the positioning plate 25 is locked by the locking pin 23 to prevent the positioning plate 25 from rotating. At this time, the positioning plate 25 can support the feeding chute 16 to prevent the feeding chute 16 from tilting downward. In the locked state, the positioning plate 25 and the traction rope 14 form an up-and-down two-way support. When the traction rope 14 breaks or becomes slack, the locking structure of the positioning plate 25 can independently bear the chute load, preventing the chute from falling out of control. In high-frequency angle adjustment scenarios, the traction rope 14 can be alternately used for driving and the positioning plate 25 can be locked to reduce the fatigue loss of the traction rope 14 and extend its service life. For multiple bags of flour sliding down at a single time, the two-way support can disperse the load to the upper and lower structures of the support plate 20, reducing stress concentration on a single component.

[0030] The embodiment of the reset connection relationship of the positioning plate 25 can be the same as that of the buffer plate 18.

[0031] Embodiment of the locking pin 23 locking the connection relationship of the positioning plate 25: A spline shaft 24 is fixedly connected to the side surface of the positioning plate 25. The spline shaft 24 is rotatably connected to the support plate 20. A threaded sleeve 22 is rotatably connected inside the support plate 20. The threaded sleeve 22 is coaxially sleeved outside the locking pin 23, and the threaded sleeve 22 is threadedly connected to the locking pin 23. When the threaded sleeve 22 is rotated, the threaded drive drives the locking pin 23 to move axially, so that its bottom end is caught between two spline teeth of the spline shaft 24 and presses against the tooth surface, thereby restricting the rotation of the spline shaft 24 and realizing the locking of the positioning plate 25.

[0032] Embodiment of controlling the rotation operation of the threaded sleeve 22: A third motor 21 is fixedly connected to the surface of the support plate 20. The output end of the third motor 21 is coaxially and fixedly connected to the end of the threaded sleeve 22. By starting the third motor 21, the threaded sleeve 22 is driven to rotate.

[0033] It further includes a roller conveyor 1. The roller conveyor 1 is fixedly installed on a high wall. The receiving tray 2 is slidably connected to the bottom end of the roller conveyor 1. The roller conveyor 1 is used to transport bagged flour into the receiving tray 2. A plurality of dropping points are provided on the surface of the roller conveyor 1. The receiving tray 2 slides at the bottom end of the roller conveyor 1 to switch the corresponding dropping points as needed. The embodiment of the sliding of the receiving tray 2 can be the same as that of the sliding of the adjusting slider 10.

[0034] The specific solution of this scheme is as follows: Before the roller conveyor 1 is started, by driving the motor installed on the side of the roller conveyor 1, the screw rod threadedly connected to the receiving tray 2 is driven to rotate, so that the receiving tray 2 slides along the T-shaped guide rail at the bottom end of the roller conveyor 1, aligning the material dropping through hole with the target dropping point of the roller conveyor 1. The bagged flour moves along the rollers of the roller conveyor 1 to the target dropping point and freely falls through the material dropping through hole of the receiving tray 2, impacting the buffer plate 18, causing the buffer plate 18 to rotate downward around the shaft, and the torsion spring 19 stores elastic potential energy to avoid directly hitting the feeding chute 16. After the flour bag slides into the feeding chute 16 along the inclined buffer plate 18, the load disappears, and the torsion spring 19 releases the elastic potential energy, generating a reset torque to drive the buffer plate 18 to reset to the horizontal state and wait for the next material to be received.

[0035] When there is a lateral deviation between the parking position of the truck and the central axis of the device, the operator starts the first motor 6, and through the meshing transmission of the transmission gear 5 and the outer gear ring of the rotating ring 4, drives the rotating ring 4 to rotate. At this time, the support rod 9, the support plate 20 and the feeding chute 16 rotate synchronously to complete the angle adjustment, and the end is oriented towards the truck carriage.

[0036] Loading height adaptive adjustment: By rotating the second motor 12, the threaded rod 11 drives the adjustment slider 10 to slide, and drives the fixed pulley 13 to move, changing the effective rope length of the traction rope 14 on the right side of the fixed pulley 13. The feeding chute 16 rotates around the rotating shaft to meet the requirements of flour stacking. When the angle is adjusted to the target value, the third motor 21 drives the threaded sleeve 22 to rotate, and the locking pin 23 moves axially, so that the bottom end is inserted into the teeth of the spline shaft 24 to form a rigid lock. At this time, the positioning plate 25 and the traction rope 14 jointly bear the chute load.

[0037] Automation linkage logic. When the sensor detects that the stacking height of flour bags at the end of the feeding chute 16 exceeds the loading height of the truck, the central control system triggers the following actions: The roller conveyor 1 pauses conveying to avoid material blockage; The first motor 6 drives the rotating ring 4 to rotate reversely by 15°, switching to other stacking areas in the carriage; The second motor 12 adjusts the inclination angle of the feeding chute 16 to adjust the height of the end; After completing the station switching, the roller conveyor 1 resumes operation to realize alternative loading in the left and right areas. Emergency handling for abnormal working conditions. If the traction rope 14 tension sensor detects a sudden change in tension, the system immediately executes: The second motor 12 stops angle adjustment; The third motor 21 starts to complete the locking of the positioning plate 25; The buzzer alarms, and after manual replacement, the lock is released to continue the operation.
