Description

Technical Field

[0001] This application relates to the field of new tobacco technology, and in particular to a passive stirring device for nicotine powder. Background Technology

[0002] According to the FDA, a nicotine pouch is a small fibrous pouch placed between the gums and upper lip for use, allowing nicotine to be absorbed through the oral mucosa. Unlike traditional tobacco products, nicotine pouches do not require combustion or heating and do not produce smoke, making them environmentally friendly.

[0003] Currently, most nicotine pouch sealing machines in China adopt traditional oral cigarette sealing equipment or are modified from food pouch and carton sealing equipment combined with traditional oral cigarette sealing processes. Early on, because nicotine pouches were mostly produced using dry processes, the equipment could basically meet production needs. However, the vulnerability of dry processes to the oral mucosa led to wet processes gradually dominating the market. The high humidity and high viscosity characteristics of wet processes meant that these machines could not adequately meet market demands, resulting in frequent shutdowns, material blockages, and low production efficiency. Existing solutions use guide plates to mix and guide the material, but due to the high humidity of the material, it frequently accumulates and adheres to the guide plates, making the prevention of adhesion and blockage ineffective. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a passive stirring device for nicotine powder that prevents nicotine powder from sticking together, accumulating, and overflowing from the hopper.

[0005] The technical solution provided by this utility model is as follows: A passive stirring device for nicotine powder is provided for stirring nicotine powder in a silo. A graduated disc, rotating continuously during operation, is located below the silo. The passive stirring device includes a roller, a linkage mechanism, a stirring rod, and stirring bars. The outer edge of the roller abuts against the graduated disc, and the roller shaft is connected to the stirring rod via the linkage mechanism. The stirring bars are mounted on the stirring rod and extend into the silo, causing the roller to roll under the rotation of the graduated disc. This rotation is transmitted to the stirring rod via the linkage mechanism, causing the stirring rod to rotate and thus stirring the nicotine powder in the silo.

[0006] Preferably, the linkage mechanism includes a first synchronous pulley group, a transmission rod, and a second synchronous pulley group. The first synchronous pulley group connects the axle and the transmission rod, and the second synchronous pulley group connects the transmission rod and the stirring rod.

[0007] Preferably, it further includes a swing arm, a tension spring, and a frame; the frame is fixed to the top plate and is provided with a rod sleeve and a synchronous pulley assembly mounting bracket; the transmission rod is rotatably fixed in the rod sleeve, and the second synchronous pulley assembly is mounted on the synchronous pulley assembly mounting bracket; the swing arm is pivotally connected to the transmission rod, and the roller and tension spring are respectively mounted at both ends of the swing arm, so that the outer edge of the roller abuts against the indexing plate under the force of the tension spring.

[0008] Preferably, it also includes a swing arm and a tension spring. The roller and the tension spring are respectively installed at both ends of the swing arm, and the outer edge of the roller abuts against the indexing plate under the action of the tension spring.

[0009] Preferably, there are multiple stirring bars.

[0010] Preferably, the roller is a rubber roller.

[0011] Compared with existing technologies, the nicotine powder passive stirring device of this utility model, by setting rollers, linkage mechanism, stirring rod and stirring bar, can prevent the filling accuracy from being affected by the adhesion and blockage of materials. It also cleverly uses the rotation of the indexing plate to achieve passive stirring, without the need to add a new power source device. It can be used to modify nicotine bag sealing machines or traditional oral cigarette sealing machines. Attached Figure Description

[0019] like Figure 1 , Figure 2 As shown, this embodiment of the invention provides a passive stirring device for nicotine powder, which can be applied to a nicotine bag sealing machine for stirring nicotine powder in a hopper 10. A dividing plate 1, which rotates continuously during equipment operation, is provided below the hopper 10.

[0020] The nicotine powder passive mixing device includes roller 2, linkage mechanism, mixing rod 7, mixing bar 9, swing arm 11, tension spring 3, and frame 8.

[0021] Roller 2 (a rubber roller in this embodiment) and tension spring 3 are respectively installed at both ends of the swing arm 11. Under the force of tension spring 3, the outer edge of roller 2 abuts against the indexing plate 1 (of course, in other embodiments, other structures can also be used to make the outer edge of roller 2 abut against the indexing plate 1). The axle of roller 2 is connected to the stirring rod 7 through a linkage mechanism. The stirring bar 9 is installed on the stirring rod 7 and extends into the hopper 10, so that roller 2 rolls under the rotation of the indexing plate 1. The rotation is transmitted to the stirring rod 7 through the linkage mechanism, causing the stirring rod 7 to rotate, so that the stirring bar 9 stirs the nicotine powder in the hopper 10. This can prevent the filling accuracy from being affected by the adhesion and blockage of the material, and promote the material feeding stability of the entire equipment. Moreover, the rotation of the indexing plate 1 is cleverly used to achieve passive stirring, without the need to add a new power source device. It can be used to modify nicotine bag sealing machines or traditional oral cigarette sealing machines. In this embodiment, there are four stirring bars 9, but other numbers are also possible. The number and spacing can be reasonably selected according to the moisture content of the nicotine powder.

[0022] In this embodiment, the linkage mechanism includes a first set of synchronous pulleys 4, a transmission rod 5, and a second set of synchronous pulleys 6. The first set of synchronous pulleys 4 connects the axle to the transmission rod 5, and the second set of synchronous pulleys 6 connects the transmission rod 5 to the stirring rod 7. This allows the rotation of the indexing disc 1 to be transmitted from the outside of the hopper 10 to the stirring bar 9 extending into the hopper 10. Furthermore, depending on the equipment from different manufacturers, only the length of the transmission rod 5 and the center distance of the second set of synchronous pulleys 6 need to be adjusted to ensure compatibility with all relevant equipment for stirring high-humidity nicotine powder.

[0023] In this embodiment, the frame 8 is fixed to the top plate 12 of the equipment, and is equipped with a rod sleeve 13 and a synchronous pulley assembly mounting bracket 14. The transmission rod 5 is rotatably fixed in the rod sleeve 13, and the synchronous pulley assembly 6 is mounted on the synchronous pulley assembly mounting bracket 14; the swing arm 11 is pivotally connected to the transmission rod 5. These structures position the transmission rod 5, the synchronous pulley assembly 6, the swing arm 11, etc., ensuring smooth operation of the roller 2, the linkage mechanism, etc. Of course, in other embodiments, other structures can be used instead.

[0024] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
