Description

Technical Field

[0001] The present invention relates to the technical field of tobacco processing equipment, and specifically relates to a tobacco strand conveying device for tobacco processing. Background Art

[0002] Tobacco strands refer to tobacco products that are cut into filaments, granules, flakes, powders or other shapes, then added with auxiliary materials, fermented and stored, and can be sold and smoked without being rolled, such as pipe tobacco, Mohe tobacco, tobacco powder, water tobacco, yellow and red tobacco strands, etc. There are various ways to use tobacco strands. It can be directly rolled into any shape with cigarette paper for smoking, or rolled into a cigarette shape with a special cigarette rolling device, or even used in combination with smoking devices such as pipes.

[0003] In factories, when it is necessary to blend tobacco strands, during the transportation process, the tobacco strands are wound together. During the transportation process, since the tobacco strands will accumulate together to form a high-density accumulation, not only will blockage occur, but it may also hinder the progress of subsequent processes, and the tobacco strands may fall off the conveyor belt, resulting in waste and other problems.

Pulley wheels are respectively and fixedly sleeved on the worm, the rotating rod, the rotating shaft and the rotating rod. A synchronous belt is wound around the plurality of pulley wheels.

[0015] The present invention has the following beneficial effects:

[0016] (1) The present invention provides a tobacco shred conveying device for tobacco processing. The driving motor is started, and the driving motor drives the rotating rod to rotate. The rotating rod drives the rotating rod and the rotating shaft to rotate under the action of the pulley and the synchronous belt. The rotating rod drives the convex roller to rotate. The convex roller drives the conveyor belt to rotate. During the process of the conveyor belt transporting the tobacco shreds, the rotating shaft drives the disc to rotate. The disc drives the connecting rod to move on the disc with the rotating shaft as the center of the circle. During the movement of the connecting rod, the semi-arc block is pushed to move in an arc on the rotating shaft. The semi-arc block drives a plurality of dispersing rods to move in an arc, and the parts of the tobacco shreds that are piled up higher during transportation are scattered, so as to avoid transportation blockage caused by excessive accumulation, and to avoid the tobacco shreds that are higher than the limiting plate and fall and cause waste;

[0017] (2) The present invention provides a tobacco shred conveying device for tobacco processing. After placing tobacco shreds into a feed port, a rotating rod rotates to drive a round roller to rotate, and the round roller drives a plurality of feed rods to rotate, so that the tobacco shreds in the feed port are pushed onto a conveyor belt for transportation. During the process of the feed rod rotating to push the tobacco shreds, a small amount of tobacco shreds will be entangled on the feed rod. During the rotation of the round roller, the push rod in the annular groove will push the tobacco shreds entangled on the feed rod to avoid a large amount of tobacco shreds entangled on the feed rod to affect the feed efficiency.

[0018] (3) The present invention provides a tobacco shred conveying device for tobacco processing. When the rotating rod rotates, the worm is driven to rotate synchronously under the action of the pulley and the synchronous belt. The worm is driven to rotate the round shaft under the action of the turbine. The rotation of the round shaft generates a suction force. Dust is sucked from the unloading position and the dropping position through two suction pipes, two suction hoods and a plurality of air inlet holes, thereby avoiding a large amount of harmful smoke and dust in the unloading and dropping process that may affect the human body. The inhaled smoke and dust are discharged into the water tank through the air outlet pipe, and the smoke and dust are treated in a dust-free manner.

[0019] (4) The present invention provides a tobacco conveying device for tobacco processing. When the tobacco falls onto the conveyor belt, impurities and heavy dust and sand on the tobacco will fall off. During the conveyor belt transportation, when the raised portion on the convex roller contacts the conveyor belt, the conveyor belt will be instantly tightened, thereby achieving a vibration effect to vibrate the dust and sand on the conveyor belt and drop them into the dust collecting box through a plurality of dust filter holes on the conveyor belt for collection. This can reduce impurities in the tobacco and effectively improve the purity of the tobacco.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
