[0034] like Figures 1 to 5 As shown in the figure, this embodiment provides a feeding and mixing device for the preparation of nicotine salt, including a mixing chamber 1, a conveying channel 2 at the top of the mixing chamber 1, a filter chamber 3 on one side of the conveying channel 2, a first motor 4 on the other side of the filter chamber 3, a spiral conveying blade 5 connected to the output end of the first motor 4, a filter assembly 6 inside the filter chamber 3, a stirring and mixing assembly 7 inside the mixing chamber 1, and a pushing assembly 8 located below the filter assembly 6 inside the filter chamber 3.

[0035] The filter assembly 6 includes a first filter screen 61, which is located inside the filter chamber 3. A second filter screen 62 is located below the first filter screen 61. Two sets of first fixing plates 63 are symmetrically arranged on the inner wall of the filter chamber 3 below the first filter screen 61. A first sliding rod 64 is provided on the top of the first fixing plate 63 and is slidably connected to the first filter screen 61. A first spring 65 is sleeved on the outer surface of the first sliding rod 64. A first T-shaped block 66 is provided at the bottom of the first filter screen 61. Two sets of second fixing plates 67 are symmetrically arranged on the inner wall of the filter chamber 3 below the second filter screen 62. A second sliding rod 68 is provided on the top of the second fixing plate 67 and is slidably connected to the second filter screen 62. A second spring 69 is sleeved on the outer surface of the second sliding rod 68. A second T-shaped block 610 is provided on the top of the second filter screen 62. A pushing mechanism is provided between the first T-shaped block 66 and the second T-shaped block 610. The raw material is filtered through the first filter screen 61 and the second filter screen 62, and impurities in the raw material are filtered out through two filtrations.

[0036] The first spring 65 is located between the first fixed plate 63 and the first filter screen 61, and the second spring 69 is located between the second fixed plate 67 and the second filter screen 62. The first spring 65 and the second spring 69 respectively drive the first filter screen 61 and the second filter screen 62 to vibrate, so as to avoid the first filter screen 61 and the second filter screen 62 from becoming blocked.

[0037] The driving mechanism includes a second motor 611, which is located at one end of the filter chamber 3. The output end of the second motor 611 is connected to a rotating shaft 612, which is rotatably connected to the filter chamber 3. A cam 613 is provided on the rotating shaft 612. The second motor 611 drives the cam 613 on the rotating shaft 612 to rotate. The cam 613 intermittently pushes the first filter screen 61 and the second filter screen 62, thereby realizing the transmission of motion.

[0038] like Figure 1 and Figure 4 As shown, the mixing assembly 7 includes a motor mounting plate 71, which is located on the top of the mixing chamber 1. A third motor 72 is located on the top of the motor mounting plate 71. The output end of the third motor 72 is connected to the main stirring shaft 73. The main stirring shaft 73 is provided with several main stirring blades 74. A secondary stirring shaft 75 is symmetrically provided on the mixing chamber 1. The secondary stirring shaft 75 is provided with several secondary stirring blades 76. The main stirring shaft 73 is provided with a connecting mechanism. The main stirring blades 74 and secondary stirring blades 76 are used to mix and stir the raw materials in the mixing chamber 1, making the raw materials more uniformly mixed, thus not affecting the purity of the nicotine salt.

[0039] The connecting mechanism includes a first gear 77, which is mounted on the main stirring shaft 73 and located inside the motor mounting plate 71. A second gear 78 is provided at the top of the auxiliary stirring shaft 75. The first gear 77 and the second gear 78 mesh with each other. The main stirring shaft 73 drives the first gear 77 to rotate, and the first gear 77 drives the auxiliary stirring shaft 75 to rotate through the second gear 78, thus realizing motion transmission.

[0040] like Figure 1 and Figure 5 As shown, the feeding assembly 8 includes a feeding ramp 81, which is located at the bottom of the filter chamber 3. A push plate 82 is provided above the feeding ramp 81, and a movable block 83 is provided on the top of the push plate 82. A drive mechanism is provided on the movable block 83. The push plate 82 pushes the raw material accumulated on the feeding ramp 81 to the bottom of the filter chamber 3, thus avoiding waste of raw material.

[0041] The drive mechanism includes a fourth motor 84, which is located on one side of the filter chamber 3. The output end of the fourth motor 84 is connected to a lead screw 85. Vertical plates 86 are symmetrically arranged on the top of the feeding inclined surface 81. The lead screw 85 is rotatably connected to one of the vertical plates 86 and threadedly connected to a movable block 83. A guide rod 87 is provided between the other vertical plate 86 and the filter chamber 3. The guide rod 87 is slidably connected to the movable block 83. The fourth motor 84 drives the lead screw 85 to rotate, and the lead screw 85 drives the push plate 82 to move along the feeding inclined surface 81 through the movable block 83, thus realizing the transmission of motion.

[0042] During use, the operator adds the raw material into the filter chamber 3, where it is filtered through the first filter screen 61 and the second filter screen 62. Impurities are removed through these two filtration processes. Simultaneously, the second motor 611 is activated, driving the cam 613 on the rotating shaft 612 to rotate. The rotating cam 613 intermittently pushes the first filter screen 61 and the second filter screen 62. The first filter screen 61 moves upward along the first slide rod 64, stretching the first spring 65 and generating tension. The tension of the first spring 65 causes the first filter screen 61 to move downward. The combined action of the cam 613 and the first spring 65 causes the first filter screen 61 to vibrate. Simultaneously, the second filter screen 62 moves downward along the second slide rod 68, compressing the second spring 69 and generating tension. The tension of the second spring 69 causes the second filter screen 62 to move upward. The combined action of the cam 613 and the second spring 69 causes the second filter screen 62 to vibrate, thus preventing clogging of the first and second filter screens 61 and 62. The filtered raw material falls onto the discharge slope 81. At the bottom of filter chamber 3, the first motor 4 is started, driving the spiral conveyor blade 5 to rotate. The spiral conveyor blade 5 transports the raw material to the mixing chamber 1. Then, the fourth motor 84 is started, driving the lead screw 85 to rotate. The lead screw 85 drives the push plate 82 to move along the feeding slope 81 through the movable block 83. The push plate 82 pushes the raw material accumulated on the feeding slope 81 to the bottom of filter chamber 3, avoiding waste of raw materials and reducing production costs. After the raw material enters the mixing chamber 1, the third motor 72 is started. The motor 72 drives several main stirring blades 74 on the main stirring shaft 73 to rotate. The main stirring shaft 73 drives the first gear 77 to rotate. The first gear 77 drives the auxiliary stirring shaft 75 to rotate through the second gear 78. The auxiliary stirring shaft 75 drives several auxiliary stirring blades 76 to rotate. The main stirring blades 74 and auxiliary stirring blades 76 mix and stir the raw materials in the mixing chamber 1, making the raw materials more uniformly mixed. This does not affect the purity of the nicotine salt, thus not affecting subsequent use. At the same time, it can save a lot of time and improve work efficiency.

[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
