Embodiment Construction
[0021] The following is a detailed description in conjunction with the drawings:
[0022] in figure 1 , The entire suction ribbon tensioning device 2 is installed on the upper surface of the air chamber 1 through the bottom plate 9. in Figure 2A , Figure 2B Among them, the suction ribbon tensioning device 2 can be roughly divided into five parts, which are a power part, a limit part, a tension part, a cleaning part and a control part.
[0023] The power part includes a leverless cylinder 11, a slider I12, a support II10, a bottom plate 9, and a sealing strip 15. The slider I12 is linearly slidably installed in the cylinder body of the leverless cylinder 11, and the leverless cylinder 11 is fixed on the support. On Ⅱ10, the support Ⅱ10 is installed on the upper surface of the bottom plate 9; the bottom plate 9 is installed on the upper surface of the air chamber 1. The upper surface of the air chamber 1 is provided with a square groove, and the bottom plate 9 is provided with a sq...

The invention discloses a tobacco shred absorbing band tensioning device and a tensioning method. The tobacco shred absorbing band tensioning device is arranged on the upper surface of an air compartment through a bottom plate. A power part comprises a rodless air cylinder, a sliding block I, a support II, the bottom plate and a sealing strip. The sliding block I is arranged inside a rodless air cylinder body in a linear sliding manner, the rodless air cylinder is fixed to the support II, and the support II is arranged on the upper surface of the bottom plate. The bottom plate is arranged on the upper surface of the air compartment, a square groove is formed in the upper surface of the air chamber, a square groove is formed in the bottom plate, and the sliding block I can stretch into the air chamber and is connected with the support I through a screw. When cigarette production is normally started, a cover plate of the air compartment is automatically closed, and a hand-operated direction valve communicates with an air path; and when the pressure on the side of a pressure adjusting valve II is higher than the pressure on the side of a pressure adjusting valve I, the pressure adjusting valve II communicates with the rodless air cylinder. The tobacco shred absorbing band tensioning device is compact in structure and stable and reliable in running and occupies less space, and the air path is easy to distribute.
Description
Technical field [0001] The invention relates to a tobacco machinery and equipment, in particular to a tensioning device and a tensioning method of a suction ribbon. Background technique [0002] In the production of cigarettes, it is necessary to tension the suction ribbon of the suction forming system to make the tensioned suction ribbon run smoothly without slipping or deviation. In the existing automatic production line of cigarette making machines, the tensioning of the suction ribbon is mostly a sliding rod type. In the sliding rod tensioning device, the sliding rod is directly driven to move by the air cylinder, thereby driving the tension wheel to move to achieve the purpose of adjusting the tension of the suction ribbon. This sliding rod type adjusting device has a simple structure and can be hidden inside the air chamber, but the positioning accuracy of the sliding rod is not high, and there is a small swing, which is easy to cause the tension wheel connected with the sl...
