Description

Technical Field

[0001] The utility model relates to the technical field of adsorption mechanisms, in particular to a fan adsorption mechanism and a conveying device for a production line conveyor belt. Background Technique

[0002] The fan adsorption mechanism is a common conveying device that uses the principle of vacuum adsorption to achieve the conveying of objects. This device usually consists of a negative pressure fan, a vacuum pump, a conveyor belt housing, and a perforated conveyor belt, etc. During operation, the negative pressure fan generates negative pressure, and the tobacco leaves or other light and thin materials are adsorbed on the conveyor belt through the perforated conveyor belt, thereby achieving continuous conveying. This mechanism has the advantages of high automation, fast working efficiency, and low labor intensity.

[0003] In the prior art, when adsorbing products on the suction belt, the negative pressure source generally used is a high-pressure fan. In order to avoid the situation of too high negative pressure, it is often necessary to install a manually adjustable air inlet on the air duct. However, the method of manually adjusting the air inlet can only rely on human experience to adjust the aperture size to limit the maximum negative pressure, and the manual operation efficiency is low. Moreover, if the adjustment operation is not carried out in time, it will cause too high negative pressure due to momentary negligence and damage the equipment. Content of the Utility Model

The fixing pin is sleeved in the upper arc-shaped groove and is slidably connected with the upper arc-shaped groove. A lower arc-shaped groove is formed on the surface of the adjusting plate.

[0011] Preferably, one side of the adjusting plate is sleeved on the fixing pin and is rotatably connected with the fixing pin. The other side of the adjusting plate is slidably connected with a sliding pin through the lower arc-shaped groove. The sliding pin is fixedly sleeved in the toothed ring.

[0025] Embodiment 3: On the basis of Embodiment 2, a reduction motor 13 is fixedly installed on one side of the positioning plate 12. The output end of the reduction motor 13 is fixedly connected to a small gear 14. A toothed ring 15 is meshed on one side of the small gear 14. The toothed ring 15 is rotatably sleeved on the fixed ring 16. The reduction motor 13 is electrically connected to an external terminal control device. The reduction motor 13 is fixedly installed on the positioning plate 12. The positioning plate 12 is fixedly installed in the air suction box 5. The reduction motor 13 drives the small gear 14 to rotate, so that the small gear 14 meshes and drives with the toothed ring 15.
