Description

Technical Field

[0001] The utility model relates to the technical field of cigarette equipment, in particular to a horizontally movable cigarette package belt conveyor. Background Art

[0002] At present, in the cigarette silk production line, cigarette pack belt conveyors are used to transport cigarette pack raw materials, providing stable and uniform cigarette pack raw materials for subsequent production processes. Cigarette pack belt conveyors are divided into three types: fixed, horizontally movable, and rotary. In cigarette factories, in order to realize the corner transportation of cigarette packs, horizontally movable cigarette pack belt conveyors and rotary cigarette pack belt conveyors are usually used together to achieve this.

[0003] Generally, the main function of the existing horizontal movable cigarette pack belt conveyor is to carry the cigarette pack and the belt conveyor to realize horizontal movement together, so as to facilitate the transportation of the cigarette pack to the rotating cigarette pack belt conveyor. However, there are generally 2 to 3 cigarette packs that need to be transported at the same time on the existing horizontal movable cigarette pack belt conveyor, and each cigarette pack weighs about 100 kilograms. After long-term use, it is found that the existing horizontal movable cigarette pack belt conveyor has the following problems:

[0004] 1. The telescopic mechanism of the horizontal mobile cigarette bag belt conveyor is driven by a cylinder, and the moving position detection device uses a magnetic detection switch installed at the front and rear ends of the cylinder. By detecting whether the cylinder is extended and retracted, it can detect whether the horizontal mobile belt conveyor is in place. The detection stroke of the existing magnetic detection switch is short, and the detection device often misdetects and misses the movement in the process of extending and retracting the cylinder. When the moving position detection device misdetects and misses the movement, maintenance personnel need to drill into the belly of the horizontal mobile conveyor to repair the magnetic detection switch on the cylinder. The space in the belly of the horizontal mobile conveyor is narrow, which is inconvenient for maintenance personnel to repair, and the maintenance time is long and there are safety risks.

[0005] 2. After the horizontal mobile cigarette pack belt conveyor is extended and retracted, there is a 30mm gap between the belt conveyor and the upstream and downstream equipment. The broken cigarette pieces on the cigarette packs can easily fall to the ground from this gap, causing pollution of the cigarette pack materials and increasing the labor intensity of the operators to clean up the fallen cigarette pack materials.

[0006] 3. During the extension and retraction process of the horizontal mobile cigarette package belt conveyor, due to the heavy weight of the cigarette packages and the belt conveyor, the air intake pressure of the cylinder is generally 5 bar. After the cylinder is extended and retracted, there is a lack of shock-absorbing blocks to unload the force on the cylinder, causing the cylinder to be easily damaged after long-term use.

[0038] Belt conveyor receiving stage:

[0039] Open the stop valve 16, and the pressure regulating valve 13 adjusts the air pressure to 5 bar. The compressed air enters the air inlet of the three-position five-way solenoid valve 11 through the stop valve 16 and the pressure regulating valve 13. When the PLC controller controls to open the extension solenoid valve 10, close the retraction solenoid valve 12. The compressed air then enters the extension air port of the cylinder 9 from the air inlet of the three-position five-way solenoid valve 11 through the extension air port of the three-position five-way solenoid valve 11 and the extension air pipe 15. Under the action of the compressed air, the cylinder 9 performs the extension action and pushes the first beam 25 forward. The first beam 25 moves forward, driving the pulley of the first pulley set 7 and the pulley of the third pulley set 26 to move forward at the same speed along the first U-shaped pulley groove 21 and the second U-shaped pulley groove 24 respectively. The first beam 25 moves forward and drives the first belt conveyor support leg 6 to move forward at the same time. And the first beam 25 moves forward to drive the third beam 29 to move forward at the same speed at the same time, and it is only necessary for the first beam 25 and the third beam 29 to be connected, which is not shown in the figure. The third crossbeam 29 moves forward, driving the pulleys of the second pulley set 18 and the pulleys of the fourth pulley set 28 to move forward at the same speed along the first U-shaped pulley groove 21 and the second U-shaped pulley groove 24 respectively. The third crossbeam 29 moves forward and drives the second belt conveyor support leg 17 to move forward. When the first crossbeam 25 moves to the first shock-absorbing block 2, the first belt conveyor support leg 6 just blocks the extended-in-place detection proximity switch 4. After the PLC controller receives the signal that the horizontal movable cigarette pack belt conveyor has extended into place, the PLC controller counts for 2 seconds and then controls the reduction motor 8 to run forward, driving the belt 1 to run forward. The first receiving tray 3 catches the broken cigarette pieces on the cigarette pack that fall from the gap between the belt 1 and the upstream equipment, completing the feeding stage of the belt conveyor.

[0040] Belt conveyor feeding stage:

[0041] Open the stop valve 16, and the pressure regulating valve 13 adjusts the air pressure to 5 bar. The compressed air enters the air inlet of the three-position five-way solenoid valve 11 through the stop valve 16 and the pressure regulating valve 13. When the PLC controller controls to open the retracting solenoid valve 12, close the extending solenoid valve 10. The compressed air then enters the retracting air port of the cylinder 9 from the air inlet of the three-position five-way solenoid valve 11 through the retracting air port of the three-position five-way solenoid valve 11 and the retracting air pipe 14. Under the action of the compressed air, the cylinder 9 performs the retracting action and pulls the first crossbeam 25 to move backward. The first crossbeam 25 moves backward, driving the pulley of the first pulley set 7 and the pulley of the third pulley set 26 to move backward at the same speed along the first U-shaped pulley groove 21 and the second U-shaped pulley groove 24 respectively. The first crossbeam 25 moves forward and drives the first belt conveyor support leg 6 to move backward at the same time. The first crossbeam 25 moves backward and drives the third crossbeam 29 to move backward at the same speed. The third crossbeam 29 moves backward, driving the pulleys of the second pulley set 18 and the pulleys of the fourth pulley set 28 to move backward at the same speed along the first U-shaped pulley groove 21 and the second U-shaped pulley groove 24 respectively. The third crossbeam 29 moves backward and drives the second belt conveyor support leg 17 to move backward. When the third crossbeam 29 moves to the second shock-absorbing block 19, the first belt conveyor support leg 6 just blocks the retracted position detection proximity switch 5. After the PLC controller receives the retracted position signal of the horizontal movable cigarette pack belt conveyor, the PLC controller counts for 2 seconds and then controls the reduction motor 8 to run forward, driving the belt 1 to run forward. The second receiving tray 20 catches the broken cigarette pieces on the cigarette pack that fall from the gap between the belt 1 and the downstream equipment, completing the feeding stage of the belt conveyor.
