Description

Rod-shaped object steering device

Technical Field

The invention relates to the field of machine manufacturing, in particular to a rod-shaped object steering device.

Background

Filter cigarettes are produced in a number of processes carried out on the surface of a cylindrical drum. The production process of the traditional filter tip cigarette is to cut a double-length cigarette from the middle part and then separate the cigarette, then put a double-length filter into the middle of two cigarettes, wrap the filter and the two cigarettes with filter tipping paper, and finally cut along the center of the filter, thereby forming two filter tip cigarettes, and the two cigarettes are symmetrically distributed along the cutting plane of the filter tip. The two filter cigarettes must be realigned so that their filter directions are aligned before being handed over to the downstream machine. This process is generally carried out by three wheel trains comprising two cone drums. This process is relatively decentralized and must be accomplished by the participation of multiple drums.

A novel cigarette, which mainly refers to a production process of a low-temperature non-combustible filter cigarette, is to cut and separate a cigarette with double length from the middle, then put the cigarette into a smoking section with double length, and then cut the cigarette from the middle of the smoking section for the second time. After cutting, the two sections of cigarettes with the cigarette sending sections are turned around in a rotating way and are symmetrically separated for a distance. After putting into double length filter in the separation department, with the filter tipping paper parcel, carry out the cubic at the filter middle part and cut to finally form two branch and have the novel filter cigarette of filter tip and section of fuming respectively.

In the production process of the novel low-temperature non-combustible filter tip cigarette, after the smoke generation section is cut according to the process requirements, the cut smoke generation section and the cigarette have to be rapidly turned around and separated on the same drum wheel, and then the next procedure can be timely carried out. Therefore, a device is necessary to simultaneously perform the turning and separating functions during the delivery of the smoking segments.

On traditional cigarette production equipment, to accomplish separation and turn round function, need separate the function that turns round the cigarette and turn to on a plurality of drums respectively, the structure is more complicated, and the drum function is more single, occupies more space.

A cigarette separating device, the technique of which can be referred to the related patent, patent application No. CN 102188046A. In this patent, the device can separate two rows of cigarettes on the surface of the roller along the axial direction, so that the requirements of the production process and the flow are met. The technology can only carry out the separation process on the cigarettes on the surface of the roller and can not carry out the turning and turning processes.

The technology of the cigarette turning device can refer to the patent document with the patent application number 94106909.5. In the technology, three drums are mutually matched, cigarettes originally positioned on the inner side or the outer side of one drum are placed on the outer side or the inner side of the drum after being rotationally turned around through two conical drums, so that two rows of cigarettes which are symmetrically placed inside and outside the drum are placed on the drum in the same side and in the same direction. The technology can realize the turning function only by using three drums, but can not separate cigarettes.

In the production process of some novel cigarettes, such as low-temperature non-combustion cigarettes, because of the requirement of the production process, a cigarette which is adsorbed on the surface of a drum wheel and has double length is cut off from the middle and then separated, smoke components such as carbon rods or batteries, atomized raw materials and the like are filled in the separation position, after the separation position is wrapped with a packaging material, the cigarette is cut off from the middle again, two cut-off cigarettes are simultaneously turned and separated, a filter tip with certain length is placed in the separation position again, and filter tip tipping paper (commonly called 'tipping paper') which is coated with glue and has proper width is wrapped outside, so that the separated cigarette and the filter tip are tightly wrapped to prevent falling. And finally, cutting off the filter tip from the middle part by using a cutter to form two symmetrically arranged filter tip cigarettes with smoking sections such as carbon rods or batteries and atomized raw materials at the heads.

In the production process of the novel cigarette, after the cigarettes are cut for the second time, a device is needed, and meanwhile, the turning and separating functions of the two cigarettes are quickly realized, so that the process flow of the whole cigarette production is prevented from being influenced. If the processes of turning, separating and the like can be realized on the same drum wheel for the two cut cigarettes, the method is very beneficial to the rapidness and the conciseness of the cigarette production process.

The production equipment of the traditional cigarette process cannot meet the production process of the novel filter tip cigarette, cannot implement separation and turning steering process on the cigarette synchronously in the conveying process of the cigarette on the same drum wheel, and cannot produce the novel low-temperature non-combustible filter tip cigarette.
