Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cigarette rod filling, in particular to a turning device for a filling machine. BACKGROUND

[0002] Low-temperature non-combustion cigarettes (commonly known as "cigarettes") are currently popular new tobacco products in Southeast Asian countries. Unlike electronic cigarettes, which are inhaled after being atomized by heating tobacco oil through electronic devices, low-temperature non-combustion cigarettes are inhaled after being smoked by directly heating tobacco raw materials through electronic devices. Since the heating temperature can be accurately controlled at about 300℃, the smoke composition is relatively stable, and the harm of harmful substances is relatively small, so it is favored by smokers. In the production of low-temperature non-combustion cigarettes, first, a composite machine is used to make a composite filter rod from a fiber rod, a cooling rod and an empty tube rod, and then a filling machine is used to fill low-temperature non-combustion tobacco particles into the cavities at both ends of the composite filter rod. After sealing and wrapping with tipping paper, the finished cigarette is obtained by cutting it into two. Since the composite filter rod in the filling machine is transported horizontally, the filling port is required to be upward during filling. In order to realize continuous and automatic production, a device is needed to change the posture of the composite filter rod. SUMMARY

[0003] In order to solve the above problems, the present application provides a filling machine turning device with simple structure, convenient turning and no influence on the appearance of the composite filter rod, which can adopt the following technical solutions:

[0020] The filling machine head turning device provided by the application comprises a rack, and further comprises:

[0021] The transmission unit has a continuous input end for connecting a driving mechanism and an output end moving intermittently in a circumferential direction.

[0022] The accommodating unit is located at the output end and has multiple cigarette stick storage positions. The cigarette stick storage positions are arranged in groups, and the cigarette stick storage positions of adjacent groups are arranged sequentially along the rotation direction of the output end.

[0023] The suction unit has an access end for connecting to the negative pressure mechanism and a suction end that communicates with the cigarette stick storage position.

[0024] The number of groups of the cigarette stick storage positions is equal to the number of times the output end stops after one circumferential rotation.

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments are based on the technical solutions of the present invention and provide detailed implementation methods. However, the scope of protection of the present invention is not limited to the following embodiments.

[0026] like Figures 1-3 As shown, a Maltese mechanism is installed inside the frame 1 of the present invention. An input shaft 22 (i.e., a continuous input end) is mounted on the driving wheel 21 of the Maltese mechanism (i.e., the drive mechanism), and an output shaft 24 (i.e., a circumferentially intermittently moving output end) is mounted on the driven wheel 23 of the Maltese mechanism. The input shaft 22 and the output shaft 24 are rotatably connected to the frame 1 via rotating bearings, and both are horizontally positioned and extend beyond the frame 1. In this embodiment, the driven wheel 23 is a grooved wheel with four radial grooves at an included angle of 90°, which undergoes four rotation-stop cycles during one revolution of the driving wheel 21.

[0027] An annular suction chamber 31 is fixedly installed on the frame 1 outside the output shaft 24. A turning block 41 is installed on the output shaft 24, which passes through the central hole of the suction chamber 31. The turning block 41 adopts an annular structure concentrically arranged with the output shaft 24. Four sets of tangential through holes 42 are evenly arranged on its outer circumference as storage positions for cigarette sticks. Each set of tangential through holes 42 has ten holes arranged in parallel. The top has a gas inlet 43 communicating with the atmosphere, and the bottom is connected to three parallel radial holes 44. The radial holes 44 are open on one side, and the outlet end is connected to the suction chamber 31. The side wall of the suction chamber 31 is provided with an inlet 32 ​​connected to the negative pressure mechanism, and the annular surface opposite to the turning block 41 is provided with a suction port 33 connected to the radial holes 44. Normally, all radial holes 44 are set with equal diameter on the turning block 41, and the suction port 33 of the suction chamber 31 is an annular port that matches the radial holes 44.

[0028] In order to realize the transfer of the cigarette rod between the horizontal transport mechanism and the vertical storage groove of the filling machine, a pushing unit is usually arranged at the entrance side of the turning block 41, and a pushing-out unit is arranged at the exit side. For example, when one group of tangential through holes 42 is turned to the side of the cigarette rod of the horizontal transport mechanism, the cigarette rod is pushed into the tangential through hole 42 by the pushing unit, then the turning block 41 is turned by 90° or 270° to make the filling port of the cigarette rod face upward, at this time, the pushing-out unit located above or below the vertical storage groove of the filling machine pushes the cigarette rod out of the tangential through hole 42 to make it enter the vertical storage groove of the filling machine.

[0029] In the description of the present application, it should be noted that the terms "left", "right", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.
