Description

Rod-shaped object conveying device

Technical Field

The invention relates to the field of machine manufacturing, in particular to a conveying device for rod-shaped objects.

Background

At present, on domestic cigarette production equipment, in the traditional cigarette production process, only two cutting and separating processes are needed for cigarettes. Firstly, cutting and separating double-length cigarettes, then putting a filter tip in the middle of the separated cigarettes, wrapping the filter tip with coated tipping paper, and carrying out secondary cutting to form two filter tip cigarettes without carbon rods or batteries and atomized raw materials. Different from the novel cigarette production process, the traditional cigarette does not need to put smoke components such as carbon rods or batteries into the cigarette head, so that the cigarette does not need to be turned around after the cigarette is cut for the first time.

On traditional cigarette production equipment, because production needs, can separate the function that turns around and turn to the cigarette respectively on different drums, the drum function is comparatively single. To perform the separating and turning functions, it is necessary to perform the separating and turning functions on a plurality of drums, and the structure is complex and occupies much space.

At present, a cigarette separating device and a turning device which are adopted on cigarette production equipment mainly separate one row of cigarettes in inner and outer rows or turn to the direction.

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 rotated and turned by two conical drums, so that two rows of cigarettes which are symmetrically placed inside and outside the drum are placed on the same side and in the same direction of the drum. 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 traditional cigarette, the processes of conveying, cutting, turning and separating cigarette are all carried out on the surface of a series of rotating cylindrical drums. 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.
