Description

U-turn device for filling machine

technical field

The invention relates to the technical field of cigarette stick filling, in particular to a U-turn device for a filling machine.

Background technique

Low-temperature non-burning cigarettes (commonly known as "cigarette bombs") are currently the best-selling new tobacco products in Southeast Asian countries. They are different from electronic cigarettes that are inhaled after being heated and atomized by electronic devices. , because the heating temperature can be precisely controlled at about 300°C, the composition of the smoke is relatively stable, and the harm of harmful substances is relatively small, so it is favored by smokers. During the production of low-temperature non-combustible tobacco, firstly, fiber rods, cooling rods and empty tube rods are made into composite filter rods through a composite machine, and then low-temperature non-combustible tobacco particles are filled in the cavities at both ends of the composite filter rods through a filling machine In the process, wrap the tipping paper after sealing, and then divide everything into two to get the finished cigarettes. Since the composite filter rods in the filling machine are mostly transported horizontally, and the filling port is required to be upward during filling, in order to realize continuous automatic production, it is necessary to design a device that can change the posture of the composite filter rods.

a transmission unit having a continuous input for connection to the drive mechanism and an output for intermittent movement in the circumferential direction;

The accommodating unit is arranged at the output end and has a plurality of storage positions for tobacco sticks, the storage positions for the tobacco sticks are arranged in groups, and the storage positions for the tobacco sticks of adjacent groups are sequentially arranged along the rotation direction of the output end;

The suction unit has an access end for connecting to the negative pressure mechanism, and a suction end connected to the storage position of the cigarette stick;

Wherein, the number of groupings of the storage positions of the cigarette rod is equal to the number of times that the output end runs in the circumferential direction and stops for a week.

The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods, but the scope of protection of the present invention is not limited to the following embodiments.

As shown in Figures 1-3, a Maltese mechanism is installed in the frame 1 of the present invention, and an input shaft 22 (i.e. a continuous input end) is installed on the driving wheel 21 of the above-mentioned Maltese mechanism (that is, the driving mechanism), and the driven wheel of the Maltese mechanism 23 is equipped with output shaft 24 (i.e. the output end of circumferential intermittent motion), input shaft 22 and output shaft 24 are connected with the frame 1 through rotating bearings respectively, and both are horizontally arranged and pass outside the frame 1. In this embodiment, the driven wheel 23 is a grooved wheel with four radial grooves at an included angle of 90°, and when the driving wheel 21 rotates once, there will be four rotation and stop cycles.

An annular pumping chamber 31 is fixedly installed on the frame 1 outside the output shaft 24 , and a U-turn block 41 is installed on the output shaft 24 passing through the central hole of the pumping chamber 31 . The above-mentioned U-turn block 41 adopts an annular structure arranged concentrically with the output shaft 24, and four groups of tangential through holes 42 are evenly arranged on its outer peripheral surface as storage positions for cigarette rods, and each group of tangential through holes 42 is arranged in parallel with ten, and the top There is an air supply hole 43 communicating with the atmosphere, and the bottom communicates with three radial holes 44 arranged side by side. The radial hole 44 is open on one side, and the outlet end communicates with the pumping chamber 31 . An inlet 32 connected to the negative pressure mechanism is provided on the side wall of the pumping chamber 31 , and a suction port 33 connected to the radial hole 44 is provided on the annular surface opposite to the U-turn block 41 . Normally, all the radial holes 44 are arranged on the U-turn block 41 with equal diameters, and the suction port 33 of the pumping chamber 31 is an annular port matching the radial holes 44 .

In order to realize the transfer of the tobacco rod between the horizontal transport mechanism and the vertical storage tank of the filling machine, a propulsion unit is usually installed on the inlet side of the U-turn block 41, and a pushing unit is installed on the outlet side. For example, when one group of tangential through holes 42 is rotated to the cigarette stick side of the horizontal transport mechanism, the cigarette stick is pushed into the tangential through holes 42 by the propulsion unit, and then the U-turn block 41 is rotated 90° or 270° to make the smoke The stick filling port faces upwards. At this time, the push-out unit located above or below the vertical storage tank of the filling machine pushes the cigarette stick out of the tangential through hole 42, so that it enters the vertical storage tank of the filling machine.
