A magnetic levitation support structure and adjustment method for the bell mouth of a cigarette machine

Abstract

The invention discloses a magnetic levitation support structure and an adjustment method for the bell mouth of a cigarette machine. The support structure includes a bell mouth seat, a support and a connecting rod. One end of the rod is rotatably connected to the support, and the other end of the connecting rod is connected to the crank drive mechanism. A guide plate is provided at the position above and below the support, which are respectively an upper guide plate and a lower guide plate; several electromagnetic devices are evenly arranged in the guide plate; There is an installation cavity in the support, the left and right sides of the installation cavity are set as open, the upper and lower sides and the front and rear sides of the installation cavity are all set to be blocked, and an electromagnetic device is also installed in the installation cavity; the two guide plates are connected with the support The electromagnetic devices on the top are mutually exclusive, so that the support is suspended between the two guide plates. The invention adopts the magnetic levitation method to support the bell mouth and the connecting rod, cancels the structure of the carbon fiber support rod, thereby effectively avoiding the problems such as the fatigue fracture of the existing carbon fiber support rod device, and can meet the needs of high-speed dynamic follow-up cutting.

Description

technical field [0001] The invention relates to the technical field of tobacco processing machinery, in particular to a magnetic levitation support structure for a bell mouth of a cigarette making machine and an adjustment method thereof. Background technique [0002] The role of the bell mouth of the cigarette maker is to provide support for the cutter head to cut the tobacco rod, and prevent the tobacco rod from drooping and deforming due to force when cutting the tobacco rod. Since the blade has a certain horizontal component speed when cutting, the horn mouth should move correspondingly to the direction of the tobacco rod. When in the cutting position, the maximum speed of the forward stroke of the horn mouth mechanism should be consistent with the speed of the tobacco rod. [0003] The trumpet mechanism of the ZJ17 cigarette maker is mainly driven by a crank and a connecting rod to reciprocate the horn. The structure supporting the horn mouth is a carbon fiber support ...

AI Technical Summary

Problems solved by technology

[0005] For example, the utility model patent with the notification number CN207821071U discloses a tobacco rod cutting device, which uses a hollow cylinder as the tobacco rod guide, so that the cigarette branch guide can not only block the upward movement of the tobacco rod, but also prevent the downward movement of the tobacco rod. The trend of movement has a blocking effect, which solves the problem that the shape of the existing cigarette pipe is inverted U-shaped, and only controls the upward movement of the tobacco rod. In actual production, the tobacco rod will be attached to the circular arc of the rotating horn mouth However, during the rotation process, even if the rotating speed is fast, the tobacco rods will intermittently swing downwards due to the gaps between the horn mouths, resulting in the cut tobacco rods not being able to smoothly enter the cigarette branch and cross the bridge, resulting in Cigarette contact, in severe cases, it will cause technical problems of cigarette running

[0006] In the prior art, a similar vibrating plate structure is used to support the bell mouth, which cannot meet the needs of high-speed dynamic follow-up cutting
