Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, and in particular to a hanging type bagged flour loading and conveying device. Background Art

[0002] In the field of grain processing, the production and transportation of bagged flour show significant characteristics of high-level production and low-level loading. The packaging production line of a grain processing plant is usually set up on a high platform. After the finished flour is packaged by an automatic packaging machine, it needs to be dropped from a high position to the truck compartment on the ground floor through conveying equipment. In this process, the conveying equipment is the key hub connecting the production end and the transportation end. Its performance directly affects the loading efficiency, material loss and operation safety.

[0003] Traditional loading equipment mostly uses rigid slides with fixed angles, which have significant defects. The landing point of traditional fixed slides is fixed, and the material receiving position must be adjusted by the lateral translation of the truck, or manual handling is required on the truck. However, it is easy for the truck to move forward and backward, but translation requires multiple directional adjustments, which is cumbersome and time-consuming. If the truck is in a narrow space, it is difficult for the truck to achieve flexible translation, resulting in large deviations in the landing point of the flour bags, requiring manual secondary handling and adjustment, 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 problem that traditional loading equipment mostly adopts a rigid slideway with a fixed angle, resulting in low loading efficiency and high labor intensity.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A suspended bagged flour loading and conveying device comprises a receiving tray, a material drop-out hole for bagged flour to pass through is provided in the middle of the receiving tray, a rotating ring is rotatably connected to 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, the surface of the support plate is rotatably connected to a feeding slide, and a traction rope for pulling the feeding slide is installed on the surface of the support rod.

[0007] Preferably, the outer ring of the rotating ring is fixedly sleeved with an outer gear ring, the bottom end of the receiving tray is rotatably connected to a transmission gear, the transmission gear is meshed with the rotating ring, and 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.

[0008] Preferably, the surface of the support rod is connected to a horizontally sliding adjustment slider, the bottom end of the adjustment slider is fixedly connected to a fixed pulley, one end of the traction rope is rotationally connected to the feeding slide, and the other end is fixedly connected to the support rod after passing around the outer groove of the fixed pulley.

[0009] Preferably, a threaded rod is rotatably connected to the surface of the support rod, a threaded hole matching the threaded rod is provided on the surface of the adjusting slider, and a second motor for driving the threaded rod to rotate is installed on the surface of the support rod.

[0010] Preferably, the inner wall of the feeding slide is fixedly connected to a limit cover, the bottom end of the limit cover is rotatably connected to a resettable buffer plate, and the limit cover is located directly below the through hole of the receiving tray.

[0011] Preferably, a torsion spring is fixedly connected between the limiting cover and the buffer plate.

[0012] Preferably, a resettable positioning plate is rotatably connected to the surface of the support plate, the positioning plate is located at the lower end of the feeding slide, and a locking pin for locking the positioning plate is installed inside the support plate.

[0013] Preferably, a spline shaft is fixedly connected to the side of the positioning plate, and the spline shaft is rotationally connected to the support plate. The locking pin is inserted between two spline teeth of the spline shaft through the bottom end and presses against the tooth surface to complete the locking of the positioning plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The loading position is adjustable to accommodate complex loading scenarios. The rotating feed slide allows the end of the slide to be flexibly adjusted in the horizontal plane, overcoming the limitations of truck translation. The placement of bagged flour across the width of the truck can be controlled without relying on lateral movement. This solves the problem of placement deviation caused by the inability of traditional fixed slides to translate, improving loading efficiency and space utilization.

[0016] 2. The angle of the feeding slide is steplessly adjustable to match different loading stages. In the early loading stage, when the truck is relatively empty, the slide angle is increased to bring the bottom of the slide closer to the bottom of the truck compartment to prevent the flour bags from impacting the compartment due to a large drop. In the later loading stage, when the flour is stacked at a higher position, the slide angle is decreased to adapt to the height of the flour stack, achieving adaptive matching at different loading stages, balancing efficiency and stacking quality.

[0017] 3. The positioning plate and locking pin provide double safety protection. During normal operation, the positioning plate automatically fits as the slide angle is adjusted, assisting in supporting the slide load, dispersing the force on the traction rope, and reducing the fatigue loss of the traction rope. When the traction rope breaks or becomes loose, the locking pin quickly locks the positioning plate to prevent the slide from falling out of control, thus avoiding safety accidents and equipment damage.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 9 , the present invention provides a technical solution.

[0030] A hanging type bagged flour loading and conveying device includes a receiving tray 2, a feeding hole for the bagged flour to pass through is provided in the middle of the receiving tray 2, the bottom end of the receiving tray 2 is rotatably connected to a rotating ring 4, the bottom end of the rotating ring 4 is fixedly connected to a support rod 9, the bottom end of the support rod 9 is fixedly connected to a support plate 20, the surface of the support plate 20 is rotatably connected to a feeding chute 16, and a traction rope 14 for pulling the feeding chute 16 is installed on the surface of the support rod 9. By driving the rotating ring 4 to rotate, the support rod 9, the support plate 20 and the feeding chute 16 can be driven. Synchronous rotation allows for flexible adjustment of the orientation of the end of the feeding chute 16. For scenarios where the truck cannot move laterally, the landing point of the bagged flour can be controlled in the width direction of the truck, solving the position deviation problem during loading using traditional fixed chutes and significantly improving loading efficiency. The inclination angle of the feeding chute 16 can be dynamically adjusted, allowing for real-time adjustment of the inclination angle of the chute so that the height of the bagged flour as it slides down from the end of the chute avoids both the shattering of the powder due to excessive drop and the impact of insufficient height on stacking order, achieving adaptive matching at different loading stages.

[0031] An embodiment of the rotating connection relationship of the rotating ring 4: a T-shaped shaft 7 is fixedly connected to the bottom end of the receiving tray 2, and an annular T-shaped slide groove 8 for matching the T-shaped shaft 7 is provided at the top end of the rotating ring 4. The horizontal flange of the T-shaped shaft 7 is engaged in the annular T-shaped slide groove 8, and the vertical axis passes through the vertical guide hole of the slide groove, so that the rotating ring 4 can rotate freely around the central axis of the receiving tray 2. At the same time, the axial separation is limited by the horizontal flange to ensure the structural stability during the rotation process.

[0032] An embodiment of controlling the rotation operation of the rotating ring 4: the outer ring of the rotating ring 4 is fixedly sleeved with an outer gear ring, the bottom end of the receiving tray 2 is rotatably connected to the transmission gear 5, the transmission gear 5 is meshed with the rotating ring 4, and a first motor 6 is installed at the bottom of the receiving tray 2, and its output shaft is coaxially fixedly connected with the transmission gear 5. When the first motor 6 is started, the motor torque is transmitted to the outer gear ring of the rotating ring 4 through the transmission gear 5, driving the rotating ring 4 to rotate at a uniform speed around the central axis, thereby realizing the direction adjustment of the feeding slide 16.

[0033] Furthermore, a reinforcement ring 3 is fixedly connected to the bottom end of the receiving tray 2, and the rotating ring 4 is coaxially rotatably connected to the reinforcement ring 3. The setting of the reinforcement ring 3 can disperse the radial load of the rotating ring 4 to the overall structure of the receiving tray 2, ensuring the stability of the feeding slide 16 during rotation and positioning.

[0034] An 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, and the rotating shaft movably penetrates the surface of the feeding chute 16, so that the feeding chute 16 rotates about 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 about the rotating shaft.

[0035] When the adjusting block 10 is driven to slide horizontally, the fixed pulley 13 moves synchronously, changing the effective rope length of the traction rope 14 on both sides of the fixed pulley 13. If the adjusting block 10 is moved 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 is reduced, and the height of the end is increased. Conversely, the adjusting block 10 is moved to the right, resulting in the length of the traction rope 14 on the right side of the fixed pulley 13 becoming longer, the inclination angle of the feeding chute 16 is increased, and the height of the end is lowered. By continuously sliding the adjusting block 10, the inclination angle of the feeding chute 16 can be steplessly adjusted within the range of 0°~45°.

[0036] An embodiment of the sliding connection relationship of the adjusting slider 10: T-shaped plates are fixedly connected to both sides of the support rod 9, and the inner surface of the adjusting slider 10 is provided with a T-shaped slot for the T-shaped plate to slide. The T-shaped plate is located in the T-shaped slot, which has the functions of carrying the guide load and constraining the rotational freedom, thereby providing a stable motion reference for subsequent angle adjustment.

[0037] An embodiment of controlling the sliding operation of the adjusting slider 10: the surface of the support rod 9 is rotatably connected to the threaded rod 11, and the surface of the adjusting slider 10 is provided with a threaded hole matching the threaded rod 11 to form a screw-nut transmission pair. The surface of the support rod 9 is installed with a second motor 12 for driving the threaded rod 11 to rotate. When the second motor 12 is energized and rotated, the torque is transmitted to the threaded rod 11, and the adjusting slider 10 performs a linear motion along the axial direction of the threaded rod 11. The forward and reverse rotation control of the second motor 12 can realize the reciprocating sliding adjustment of the adjusting slider 10 within the range of the support rod 9.

[0038] An embodiment of the rotational connection relationship of the traction rope 14: the end of the traction rope 14 is fixedly connected to the connecting shaft block 15, and the connecting shaft block 15 is rotationally connected to the feeding chute 16. The installation position of the connecting shaft block 15 is located near the end of the lower end of the feeding chute 16, forming an eccentric pulling point, ensuring that the tension action line of the traction rope 14 deviates from the center of gravity of the chute, generating an effective rotational torque.

[0039] Furthermore, the inner wall of the feeding chute 16 is fixedly connected to a limit cover 17, and the bottom end of the limit cover 17 is rotatably connected to a resettable buffer plate 18. The limit cover 17 is located directly below the through hole of the receiving tray 2, and the limit cover 17 is located at the end close to the highest point of the feeding chute 16. When the bagged flour falls freely from the through hole of the receiving tray 2, it falls onto the buffer plate 18. The gravity of the flour overcomes the initial torque of the buffer plate 18 and drives the buffer plate 18 to rotate downward around the axis. In this process, the torsional damping effect of the buffer plate 18 absorbs the impact energy of the flour and reduces 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 is reset to a horizontal state, ready for the next drop, thereby buffering the bagged flour and avoiding the problem of flour bag damage or powder overflow caused by direct impact of traditional rigid slides.

[0040] An embodiment of the resettable connection relationship of the buffer plate 18: a torsion spring 19 is fixedly connected between the limit cover 17 and the buffer plate 18. In the initial state, the torsion spring 19 maintains a pre-twisted angle of 5° to keep the buffer plate 18 in a horizontal position. 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 produces 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 in the opposite direction around the axis. The torque overcomes the rotational inertia and friction resistance of the buffer plate 18 itself, and resets the buffer plate 18 to the initial horizontal position, completing a buffer cycle.

[0041] Furthermore, a resettable 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 slide 16. The positioning plate 25 has a tendency to reset to a horizontal state. By setting the positioning plate 25 to be resettable, when the feeding slide 16 is tilted downward to adjust the angle, it will press the positioning plate 25 to rotate with it. When the feeding slide 16 is tilted upward to adjust the angle, the positioning plate 25 will automatically reset under the action of elastic force, and always remain close to the lower end of the feeding slide 16. A locking pin 23 for locking the positioning plate 25 is installed inside the support plate 20. When the feeding slide 16 is adjusted to the target angle, the positioning plate 25 is locked by the locking pin 23. 5 prevents 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 a two-way support in the upper and lower directions. When the traction rope 14 breaks or becomes loose, the locking structure of the positioning plate 25 can independently bear the load of the chute, preventing the chute from falling out of control. In high-frequency angle adjustment scenarios, the traction rope 14 can be used alternately to drive and lock the positioning plate 25, reducing fatigue loss of the traction rope 14 and extending its service life. For multiple bags of flour sliding down at a time, the two-way support can distribute the load to the upper and lower structures of the support plate 20, reducing stress concentration on a single component.

[0042] The embodiment of the resettable connection relationship of the positioning plate 25 may be the same as the resettable connection relationship of the buffer plate 18 .

[0043] An embodiment of the connection relationship of the locking pin 23 locking the positioning plate 25: a spline shaft 24 is fixedly connected to the side of the positioning plate 25, and the spline shaft 24 is rotatably connected to the support plate 20. The inside of the support plate 20 is rotatably connected to a threaded sleeve 22, and the threaded sleeve 22 is coaxially sleeved on the outside of the locking pin 23, and the threaded sleeve 22 and the locking pin 23 are threadedly connected. When the threaded sleeve 22 is rotated, the threaded transmission drives the locking pin 23 to move axially, so that its bottom end is stuck between the two spline teeth of the spline shaft 24 and pressed against the tooth surface, thereby limiting the rotation of the spline shaft 24 and achieving the locking of the positioning plate 25.

[0044] An 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, and the output end of the third motor 21 is coaxially fixedly connected to the end of the threaded sleeve 22, and the threaded sleeve 22 is driven to rotate by starting the third motor 21.

[0045] It also includes a roller conveyor 1, which 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 to the receiving tray 2. The surface of the roller conveyor 1 is provided with multiple drop points. The receiving tray 2 slides at the bottom end of the roller conveyor 1 to switch the corresponding drop points as needed. The embodiment of the sliding of the receiving tray 2 can be the same as the embodiment of the sliding of the adjustment slider 10.

[0046] The specific scheme is as follows: before the roller conveyor 1 is started, the motor installed on the side of the roller conveyor 1 is driven to drive the screw threadedly connected to the receiving tray 2 to rotate, so that the receiving tray 2 slides along the T-shaped guide rail at the bottom end of the roller conveyor 1, and the blanking hole is aligned with the target dropping point of the roller conveyor 1. The bagged flour moves to the target dropping point with the roller of the roller conveyor 1, and falls freely through the blanking hole of the receiving tray 2, impacting the buffer plate 18, causing the buffer plate 18 to rotate downward around the axis, and the torsion spring 19 stores elastic potential energy to avoid direct impact on the feeding chute 16. After the flour bag slides into the feeding chute 16 along the inclined buffer plate 18, the load disappears, the torsion spring 19 releases the elastic potential energy, generates a reset torque, and drives the buffer plate 18 to reset to a horizontal state, waiting for the next material to be received.

[0047] When there is a lateral deviation between the docking position of the truck and the central axis of the device, the operator starts the first motor 6, which drives the rotating ring 4 to rotate through the engagement of the transmission gear 5 with the outer gear ring of the rotating ring 4. At this time, the support rod 9, the support plate 20 and the feeding slide 16 rotate synchronously to complete the angle adjustment, and the end is aligned with the truck compartment.

[0048] Adaptive adjustment of loading height: The second motor 12 rotates, the threaded rod 11 drives the adjusting 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, and the feeding slide 16 rotates around the rotation axis 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 stuck between the teeth of the spline shaft 24, forming a rigid lock. At this time, the positioning plate 25 and the traction rope 14 jointly bear the slide load.

[0049] Automatic 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:

[0050] Roller conveyor 1 suspends conveying to avoid material blockage;

[0051] The first motor 6 drives the rotating ring 4 to rotate 15 degrees in the opposite direction and switch to the stacking area at other positions in the carriage;

[0052] The second motor 12 adjusts the inclination angle of the feeding slide 16 and the height of the end;

[0053] After the workstation switching is completed, roller conveyor 1 resumes operation, realizing alternating loading in the left and right areas.

[0054] Emergency handling of abnormal working conditions: if the traction rope 14 tension sensor detects a sudden change in tension, the system immediately executes:

[0055] The second motor 12 stops angle adjustment;

[0056] The third motor 21 is started to lock the positioning plate 25;

[0057] The buzzer will sound an alarm, and the lock will be unlocked after manual replacement to continue working.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
