Description

Technical Field

[0001] This application relates to the field of tobacco conveying equipment technology, specifically to an extension device for a cigarette box opening conveyor. Background Technology

[0002] In tobacco production, cigarette box unpacking conveyors are an indispensable piece of equipment. However, traditional cigarette box unpacking conveyors have certain limitations in practical use. With the expansion of production scale and the increase in production efficiency requirements, the length of existing cigarette box unpacking conveyors often cannot meet the needs of the conveying distance. For example, in some large tobacco production workshops, the distance from the cigarette box storage area to the unpacking and processing area is relatively long. Ordinary conveyors cannot directly transport the cigarette boxes to their destination, requiring multiple transfers. This not only increases labor and time costs but also easily damages the cigarette boxes during transfers, affecting the quality of the tobacco inside.

[0003] Furthermore, traditional cigarette box unpacking conveyors have shortcomings in the connection between conveying links at different heights. For example, when conveying cigarette boxes from a lower buffer area to a higher processing equipment, an efficient and smooth transition cannot be achieved, which can easily lead to problems such as cigarette boxes jamming or falling, affecting the continuity and stability of production.

[0027] Specifically, the bottom of the first support frame 4, the second support frame 6, and the support base 8 are all fixed with adjustable feet 13 by bolts, which are used to adjust according to the ground conditions to ensure the stability of the device. The adjustable feet 13 are existing technology and can be purchased from the market.

[0028] Example 2:

[0029] like Figure 1-4 As shown, this utility model discloses another technical solution, an extension device for a cigarette box opening conveyor. The difference from embodiment 1 is that the first conveying component 5, the second conveying component 7, and the third conveying component 10 have the same structure, all including a support frame 14 arranged at the front and rear. Multiple sets of conveying rollers 15 are rotatably connected between the two support frames 14 along their length direction via bearings, and the conveying rollers 15 are driven to rotate by a drive motor 16 to achieve stable conveying of the cigarette box. In this embodiment, each set is provided with eleven sets of conveying rollers 15, and three drive motors 16 are installed on each conveying component. Two conveying rollers 15 are provided between two adjacent drive motors 16, which saves costs while ensuring the conveying of the cigarette box.

[0030] Specifically, the second sensor group 11 uses a grating sensor and is installed on the front and rear sides of the upper surface of the support frame 14. Two symmetrically arranged guide rods 17 are also installed between the front and rear support frames 14 along their length to guide the conveying direction of the smoke box and prevent the smoke box from deviating.

[0031] Example 3:

[0032] like Figure 1-4 As shown, this utility model discloses another technical solution, a cigarette box opening conveyor extension device. The difference from embodiment 1 is that the bottom of the third conveying component 10 is fixedly connected to a support platform 18 by bolts. Slider blocks 19 are symmetrically installed on the left and right sides of the rear side of the support platform 18. The front side of the third support frame 9 is provided with a slide rail 20 that works with the slider 19. The slide rail 20 is vertically arranged, and the slider 19 can move up and down along the slide rail 20, which further ensures the stability and reliability of the lifting and lowering of the third conveying component 10. The support base 8 and the third support frame 9 are also equipped with a first sensor group 12 for detecting the position of the third conveying component 10, including two proximity switches, which are respectively installed on the upper part of the third support frame 9 and the upper surface of the support base 8, so that the control system can accurately control the lifting and lowering position of the third conveying component 10.

[0033] Specifically, the lifting assembly consists of a linear drive assembly 21, a support block 22, a support shaft 23, a sprocket 24, and a chain 25. The linear drive assembly 21 can be a push rod motor, a hydraulic cylinder, or a pneumatic cylinder. The fixed end of the linear drive assembly 21 is fixedly installed on the upper surface of the support base 8 by bolts.

The lower conveyor module 1 and the upper conveyor module 2 are located at different heights to meet the conveying needs at different heights within the workshop. The lifting conveyor module 3 is located between the lower conveyor module 1 and the upper conveyor module 2. The lifting assembly enables the third conveyor component 10 to move up and down to dock with the first conveyor component 5 and the second conveyor component 7. During the conveying process, the first sensor group 12 detects the position information of the third conveyor component 10 in real time and transmits the signal to the control system. The control system controls the lifting assembly to perform lifting operations based on the position information of the third conveyor component 10, ensuring accurate docking of the third conveyor component 10 with the first conveyor component 5 and the second conveyor component 7. At the same time, the second sensor group 11 detects the position information of the cigarette box in real time and transmits the signal to the control system.
