Description

Technical Field

[0001] This utility model relates to the technical field of cigarette air separation equipment, and in particular to a secondary air separation mechanism for cigarette machines with adjustable air inlet compensation holes. Background Technology

[0002] The secondary air separation mechanism of the ZJ17 cigarette machine further separates the stems and tobacco shreds separated by the primary air separation. It utilizes the different suspension velocities of the stems and tobacco shreds to separate and utilize the tobacco. The suspension velocity of the suction air is V. 风 When the levitation speed of the tag is V 梗 <V 风 At that time, the stem stick will fall into the stem receiving box; when the suspension speed of the tobacco is V 梗 <V 风 At that time, the tobacco will be sucked onto the suction belt and enter the suction duct along with the suction belt.

[0003] There are two methods to adjust the suction volume in a secondary air separation mechanism: one is to adjust the lower throttling damper, thereby adjusting the suspension velocity of the suction air by opening and closing the damper; the other is to adjust the number of upper air inlet compensation holes to change the suspension velocity of the suction air. The bottom throttling damper can be adjusted arbitrarily, while the number of upper air inlet compensation holes is generally adjusted by partially blocking some holes with adhesive materials such as tape. Adjusting the number of upper air inlet compensation holes using adhesive materials is not easy to do flexibly and easily, and the adhesive material will leave the surface of the secondary air separation mechanism covered with glue residue. Therefore, the technical problem to be solved is how to achieve a quick and convenient adjustment of the number of upper air inlet compensation holes. Utility Model Content

[0025] Example 1

[0026] like Figures 1-4 As shown:

[0027] A secondary air separation mechanism for a cigarette machine with adjustable air inlet compensation holes includes a secondary air separation mechanism and a device for adjusting the number of compensation holes, wherein:

[0028] like Figure 4 As shown, the secondary air separation mechanism includes a baffle plate 10, a throttling damper 11 at the bottom of the baffle plate 10, and several air inlet compensation holes 12 at the top of the baffle plate 10. Specifically, as... Figure 4 As shown, the lower part of the baffle plate 10 is vertically arranged, and the lower part of the baffle plate 10 is provided with an air outlet. A throttling damper 11 is provided on the air outlet. The size of the air outlet can be adjusted by raising and lowering the throttling damper 11, thereby adjusting the air volume.

[0029] The upper and lower parts of the baffle plate 10 are inclined, with the upper part of the baffle plate 10 tilted backward. A number of air inlet compensation holes 12 are evenly arranged on the upper part of the baffle plate 10 in a matrix arrangement. In order to change the suspension speed of the suction air, it is necessary to adjust the number of air inlet compensation holes. Therefore, a compensation hole number adjustment device is provided on the upper part of the baffle plate.

[0030] like Figure 1 and Figure 2 As shown, the compensation hole quantity adjustment device includes a cover plate 1, a guide block 2, and an adjusting bolt 6. The cover plate 1 has two parallel elongated slots 13. The cover plate 1 is completely parallel to the plane where the air inlet compensation hole is located, and the contact surface is smooth. The two elongated slots 13 on the cover plate 1 are parallel, and the width of the elongated slots 13 is slightly larger than the width of the guide block 2, but without causing obvious shaking. There are no specific requirements for the size of the cover plate 1, as long as it can completely cover the air inlet compensation hole.

[0031] like Figure 3As shown, there are two guide blocks 2. Each guide block 2 is cuboid in shape, with a blind hole 8 containing a screw thread at its upper part. The internal thread within the blind hole 8 engages with a fastening screw 5. Two countersunk holes are located in the area of ​​the air inlet compensation hole on the wind deflector. The fastening screw 5 passes through these two countersunk holes to fix the guide block 2 to the wind deflector. The distance between the two countersunk holes is the same as the distance between the two elongated slots 13, ensuring that the distance between the two guide blocks 2 is the same as the distance between the two elongated slots 13, allowing the two guide blocks 2 to be embedded into the corresponding elongated slots 13. The guide blocks 2 are fixed in the air inlet compensation hole area without interfering with the air inlet compensation hole, and the guiding direction is vertical.

[0032] Two parallel elongated slots 13 are provided on the cover plate 1 so that the guide block 2 can be embedded in them; the cover plate 1 slides relative to the two guide blocks 2 through the two elongated slots, so that the cover plate 1 can slide relative to the wind baffle 10, and then cover an appropriate number of air inlet compensation holes 12 by the up-and-down sliding cover plate 1, thereby adjusting the number of air inlet compensation holes.

[0033] To secure the cover plate 1 after it slides into place, a through hole 9 is provided at the bottom of the guide block 2. An adjusting bolt 6 passes through the air inlet compensation hole on the baffle plate and the through hole on the guide block 2, and is tightened by a nut 7. Simultaneously, two washers 3 and a spring 4 are also provided on the adjusting bolt 6. One washer 3 is placed on the outer surface of the guide block 2, and then the spring 4 and the other washer 3 are sequentially placed on the adjusting bolt, which is then tightened by the nut 7. Under the pressure of the nut 7, the spring 4 presses against the cover plate 1, causing the cover plate 1 to be pressed against the air inlet compensation hole area.

[0034] The cover plate 1 is pressed down by washers 3 and springs 4, which keeps the cover plate 1 in a state of compression with the air inlet compensation hole area. The degree of compression is adjusted by nuts 7. The cover plate 1 can slide back and forth along the guide direction of guide block 2 under the action of external force, so as to adjust the number of air inlet compensation holes, and finally adjust and fix it by nuts 7.

[0035] This invention, by setting a compensation hole number adjustment device, can quickly adjust the air separation effect of the secondary air separation mechanism of the ZJ17 cigarette machine, and can arbitrarily adjust the number and size of the air inlet compensation holes.

[0036] This utility model installs a compensation hole number adjustment device on the secondary air separation mechanism of the ZJ17 cigarette machine. When the filament content in the stem stick that falls out of the bottom of the secondary air separation mechanism is less than the process requirement, the cover plate 1 is slid down until the filament content in the stem stick reaches the process requirement; when the filament content in the stem stick that falls out of the bottom of the secondary air separation mechanism is greater than the process requirement, the cover plate 1 is slid up until the filament content in the stem stick reaches the process requirement.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
