Description

Technical Field

[0001] This utility model relates to the field of tobacco handling and loading stacking technology, specifically to a tobacco bag lifting, transfer and stacking device with adjustable cantilever shape. Background Technology

[0002] The handling and temporary storage of tobacco bales are routine tasks at tobacco purchasing stations. Each day, the purchased tobacco leaves are baled by a baler and then immediately transported to designated temporary storage locations. Due to the large daily production volume and frequent transport, with each bale weighing a constant 40-50 kg, the current practice is to manually handle and stack each bale one by one. This requires a significant amount of manpower and physical strength, resulting in a substantial daily physical strain. Furthermore, in some areas, hand hooks are used to drag the bales, which inevitably damages the tobacco leaves to some extent, hindering the development of modern tobacco processing. The application of a tobacco bale transfer and stacking device can greatly reduce manual labor intensity, improve efficiency, require fewer personnel, and alleviate manual labor, making it an ideal auxiliary device for the tobacco purchasing process at tobacco purchasing stations.

[0020] like Figure 1 Figure 2 As shown, a cigarette pack lifting and stacking device includes a movable support base 1. The support base 1 includes a frame-type support 101. The bottom of the support 101 is equipped with pulleys 102, which are installed at the four corners of the bottom of the support 101.

[0021] The mobile support base 1 is equipped with counterweights 2. Generally, there are two counterweights 2 to ensure the balance of the center of gravity of the support base 1. The counterweights 2 are symmetrically distributed on both sides of the support 101 to ensure the stability of the equipment during movement.

[0022] The column 3 is vertically fixed in the center of the bracket 101. A rotating shaft 4 is installed on the top, which can rotate counterclockwise or clockwise. A crank arm 5 is installed on the rotating shaft 4. A lever arm 6 is hinged to the end of the crank arm 5 away from the column 3. The lever arm 6 is hinged to the crank arm 5 through a cylindrical hinge. The lever arm 6 can swing up and down along the hinge point. A lever arm cylinder 7 is hinged to the lower side of the lever arm 6 on the crank arm 5. The lever arm cylinder 7 is connected to the crank arm 5 through a hinge seat 8. The extension and retraction point of the lever arm cylinder 7 is hinged to the lever arm 6. The extension and retraction of the lever arm cylinder 7 drives the lever arm 6 to swing up and down. The structure is similar to the boom system of an excavator.

[0023] A lifting cylinder 8 is installed at the end of the lever arm 6 away from the column 3. The telescopic end of the lifting cylinder 8 is hinged to the end of the lever arm 6, and the lower base end of the lifting cylinder 8 is hinged to the base plate 902 of the gripping mechanism 9.

[0024] The gripping mechanism 9 includes a base plate 902, and grippers 903 for holding cigarette packs are rotatably mounted on both sides of the base plate 902. The grippers 903 are mounted on the base plate 902 via a rotating shaft 905, that is, the two ends of the rotating shaft 905 are inserted into the bearing seats on the base plate 902.

[0025] The gripping mechanism 9 is equipped with two clamping cylinders 904, whose telescopic rod ends move towards each other. A rotating shaft 905 is hinged to the telescopic ends of the clamping cylinders 904; that is, a connecting rod is fixedly mounted on the rotating shaft 905, and the connecting rod is hinged to the telescopic ends of the clamping cylinders 904. The opening and closing of the gripper 903 is controlled by the extension and retraction of the cylinders, achieving a stable gripping of the cigarette pack. The clamping cylinders 904 are hinged to the mounting base 906 (not shown in the figure) via cylinder seats. The mounting base 906 is fixed to the base plate 902, ensuring stable operation of the clamping cylinders 904.

[0026] It also includes an operating handle 10, which is mounted on the gripping mechanism 9. The operating handle 10 has a control panel 11 mounted on it, which controls the lever arm cylinder 7, lifting cylinder 8, and clamping cylinder 904. The pipelines of the lever arm cylinder 7 and clamping cylinder 904 are arranged along the column 3, etc. To reduce the impact of the pipelines on operation, the pipelines can be routed inside the column 3 using a hollow tube structure, and a pipeline inlet is provided on the lower side of the column 3. Figure 3 As shown, this design ensures flexible operation. The control panel 11 is equipped with buttons and switches, allowing operators to precisely control cylinder movements and improve work efficiency. The overall design is compact, combining aesthetics and practicality, and is suitable for various working environments.

[0027] In use, the operator grips handle 10 with both hands, rotates lever 6 to the desired position, and controls lever cylinder 7 via control panel 11 to retract and extend lever 6 above the cigarette pack. Then, the operator controls lifting cylinder 8 to lower or raise the cigarette pack, and clamping cylinder 904 to push clamp 903 to hold the cigarette pack. This achieves the clamping, lifting, lowering, and rotating of the cigarette pack, allowing it to be placed in a designated location for transport and stacking. The machine is safe, reliable, simple, practical, and easy to transport, fundamentally solving the problems of large quantities of cigarette packs, high labor intensity, and high manual labor input in transporting and stacking.
