Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to a feeding mechanism of a packaging machine. Background Art

[0002] A packaging machine is a special equipment used to package materials, in which the feeding mechanism is used to feed the materials to the packaging station for packaging processing. At present, a type of feeding mechanism on the market needs to use a mechanical arm structure to drive the material to transfer. Its structure is relatively complex, the production cost is high, and the speed of the mechanical arm is limited, resulting in low efficiency in material transportation. In addition, the traditional feeding mechanism, when placed downward, is in direct contact with the feeding conveyor belt, which results in a large contact friction between the material and the moving conveyor belt, causing the material to deform or shift in position, affecting the stability of material transportation. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a feeding mechanism of a packaging machine for solving the above-mentioned problem.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0005] A feeding mechanism of a packaging machine, characterized in that it includes a stacking rack, a material blocking piece is arranged at the opening at the bottom of the stacking rack, a feeding platform is arranged below the stacking rack, a feeding belt is arranged corresponding to the feeding platform, pushing blocks are arranged on the feeding belt, the feeding platform is provided with a clearance hole at a position corresponding to the stacking rack, a suction nozzle is arranged at the corresponding clearance hole, the suction nozzle is connected to the lifting drive assembly, driving the suction nozzle to reciprocate between the stacking rack and the feeding platform, a supporting piece is arranged at the clearance hole near the feeding platform, the supporting piece is higher than the feeding belt, and the supporting piece has a clearance groove for the suction nozzle to pass through.

[0006] A plurality of feeding belts are arranged at intervals.

[0007] The material blocking member comprises an L-shaped material blocking plate, which comprises a material blocking portion horizontally extending to the bottom opening of the material stacking rack, and a guide portion extending downwardly at the end of the material blocking portion.

[0008] The feeding platform is provided with side baffles extending upwards near the feeding belts on both sides.

[0009] It also includes a first motor, which is drivingly connected to a feeding belt wheel, and the feeding belt passes around the feeding belt wheel.

[0010] The lifting drive assembly includes a second motor, which is drivingly connected to a drive shaft. A turntable is connected to the drive shaft. The turntable is eccentrically hinged to one end of a transmission arm, and the other end of the transmission arm is hinged to a lifting seat. A sliding seat is connected to the lifting seat, and a slide rail cooperating with the sliding seat is provided on the frame. The suction nozzle is provided at the top of the lifting seat.

[0011] The feeding mechanism of a packaging machine with the above technical solution has a simple structure and reasonable design. Only by setting a liftable suction nozzle, a feeding platform and a feeding belt can the suction and transfer of materials be cooperatively carried out, replacing the structure of a mechanical hand for transfer, effectively reducing its production cost, making its feeding efficiency higher and the feeding stability better. At the same time, a material supporting member is provided to avoid the direct contact between the material and the moving feeding belt, which can effectively eliminate the contact friction between the material and the feeding belt, thereby ensuring that the material will not be deformed or its position will not shift, and ensuring the stability of material transportation.

[0018] As shown in the figure, the feeding mechanism of a packaging machine disclosed in the utility model includes a stacking rack 1, and a material blocking member is arranged at the opening at the bottom of the stacking rack 1. In this embodiment, the material blocking member includes an L-shaped material blocking plate, and the material blocking plate has a material blocking portion 6 extending horizontally to the bottom opening of the stacking rack, and a guide portion 7 extending downward at the end of the material blocking portion 6. A feeding platform 3 is arranged below the stacking rack 1, and a feeding belt 4 is arranged corresponding to the feeding platform 3. Pushing blocks 5 are arranged on the feeding belt 4. In this embodiment, a plurality of feeding belts 4 are arranged at intervals, and a synchronous feeding operation of multiple materials can be realized at one time. It also includes a first motor 13, and the first motor 13 is connected to the feeding pulley 12 through the first synchronous belt transmission group 2. The feeding belt 4 bypasses the feeding pulley 12. By controlling the first motor 13 to start, the feeding pulley 12 is driven to rotate, and the action of the feeding belt 3 can be realized. The feeding platform 3 is provided with a clearance hole 11 at a position corresponding to the stacking rack 1, and a suction nozzle 8 is arranged at the corresponding clearance hole 11. The suction nozzle 8 is connected to the lifting drive assembly to drive the suction nozzle 8 to reciprocate between the stacking rack 1 and the feeding platform 3. In summary, the lifting drive assembly includes a second motor 14, and the second motor 14 is connected to the driving shaft through a second synchronous belt transmission assembly 15. A turntable 16 is connected to the driving shaft, and the turntable 16 is eccentrically hinged to one end of a transmission arm 17. The other end of the transmission arm 17 is hinged to a lifting seat 18. A slide seat 19 is connected to the lifting seat 18, and a slide rail 20 cooperating with the slide seat 19 is arranged on the frame. The suction nozzle 8 is arranged on the lifting seat 18, and the turntable 16 is driven to rotate by controlling the second motor 14. The transmission is transmitted through the transmission arm 17, so that the lifting seat 18 can be driven to lift and lower under the guidance of the slide rail 20. Furthermore, the feeding platform 3 has side baffles 10 extending upward near the feeding belts on both sides, which can achieve the limitation on both sides, prevent the material from escaping from the feeding platform 3 during the conveying process, and improve the stability of material conveying. A support piece 9 is provided near the clearance hole 11 of the feeding platform 3. The support piece 9 is higher than the feeding belt 4. The support piece 9 has a clearance groove 21 for the suction nozzle to pass through. By providing the support piece 9, the material can be placed on the support piece 9 first after being sent down, avoiding the material from directly contacting the moving feeding belt 4, and can effectively eliminate the contact friction between the material and the feeding belt 4, thereby ensuring that the material will not be deformed or shifted, and ensuring the stability of material conveying.

[0019] The working principle of the utility model is as follows: materials are stacked in the stacking rack 1, and the materials at the bottom are placed on the material blocking part 6, the lifting seat 18 drives the suction nozzle 8 to rise to the materials at the bottom of the stacking rack 1 and suck the materials, and then the lifting seat 18 drives the suction nozzle 8 to descend, pulling the materials downward to leave the material blocking part 6 and guide them down to the material supporting part 9 through the guide part 7, when the pushing block 5 on the feeding belt 4 moves to the vicinity of the material supporting part 9, it pushes the materials away from the material supporting part 9 and onto the feeding belt 3, and drives the materials to be transported outward as the feeding belt 3 moves.

[0020] With this structure of the utility model, only a liftable suction nozzle, a feeding platform and a feeding belt need to be set up, which can cooperate to suck and transfer materials, replacing the structure of mechanical hand transfer, effectively reducing its production cost, making its feeding efficiency higher and the feeding stability better. At the same time, a material supporting member is set to prevent the material from directly contacting the moving feeding belt, which can effectively eliminate the contact friction between the material and the feeding belt, thus ensuring that the material will not be deformed or displaced, and ensuring the stability of material transportation.
