[0033] The following is a further detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention, and are not intended to limit the present invention.

[0034] In the description of the present invention, it should be noted that the terms "front", "convex", and "outer" orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0035] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, it can mean direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model based on specific circumstances.

[0036] Figure 1 This is the main view of the smoke separation wheel of the utility model. In the following description, Figure 1 The direction reference defines the axial direction of the smoke separation drum 2 as the front-to-back direction, and the flange 3 is located at the front end of the smoke separation drum 2.

[0037] The utility model provides a smoke separating wheel of a filter rod forming machine, which is used for receiving filter rods and driving the filter rods to rotate. After the filter rods reach a designated position, the smoke receiving wheel receives the filter rods.

[0038] like Figure 1-Figure 2 As shown, the smoke separation wheel of the filter rod forming machine of the present invention includes a smoke separation drum 2 and an end cover 1. The smoke separation drum 2 is provided with a negative pressure chamber 21. The outer wall of the smoke separation drum 2 is provided with a plurality of suction grooves 23 spaced apart along the circumference of the smoke separation drum 2. Each suction groove 23 extends in the front-to-back direction. The side wall is provided with a plurality of negative pressure holes 22 spaced apart along the extension direction of the suction groove 23. Each negative pressure hole 22 is connected to the negative pressure chamber 21. A partition 24 is also provided between two adjacent suction grooves 23.

[0039] Specifically, the negative pressure chamber 21 is connected to a negative pressure extraction mechanism, which continuously extracts gas from the negative pressure chamber 21, creating a negative pressure environment at the negative pressure holes 22 and suction grooves 23. Filter rods received by the smoke separation drum 2 are then attracted to the suction grooves 23 and rotate synchronously with the smoke separation drum 2. The isolation portion 24 is used to separate adjacent filter rods and limit their circumferential displacement along the smoke separation drum 2. The negative pressure extraction mechanism is conventional technology, and a negative pressure fan can be used as an alternative.

[0040] The end cover 1 is detachably connected to the front end of the cigarette dividing drum 2, and a plurality of air holes 11 are formed on the end cover 1 and spaced along the circumferential direction of the end cover 1. The axial direction of the air holes 11 is parallel to the front-rear direction, and the air holes 11 are in communication with the air suction groove 23, and the number of the air holes 11 is the same as that of the air suction groove 23 and arranged one by one in correspondence. The air holes 11 are in communication with the outside, and when a negative pressure environment is formed near the air suction groove 23, the outside air will flow to the air suction groove 23 through the air holes 11, and the filter rod will be subjected to a backward thrust in addition to the suction force of the air suction groove 23. Therefore, the air holes 11 can play a buffering role for the filter rod, which can prevent the filter rod from colliding with the end cover 1 and avoid quality problems such as head collision and crease, and help the filter rod to reach the predetermined position in the air suction groove 23 for subsequent receiving by the cigarette receiving wheel. At the same time, the surface of the end cover 1 is provided with an anti-sticking layer, which can effectively reduce the accumulation of glue and prevent the filter rod from sticking to the end cover 1. The anti-sticking layer is specifically made of Teflon material, which has the characteristics of low friction, high temperature resistance and aging resistance, thereby effectively reducing the accumulation of glue. The end cover 1 is preferably made of aluminum alloy material, which has the characteristics of high strength, corrosion resistance and light weight.

[0041] Specifically, the flange 3 connected with the cigarette dividing drum 2 and the end cover 1 is further provided with a sealing cover, which can seal one end of the negative pressure cavity 21 close to the end cover 1.

[0042] Specifically, the end cover 1 is further provided with a plurality of first connecting holes 12 and second connecting holes 13. The axial direction of the first connecting holes 12 is parallel to the axial direction of the cigarette dividing drum 2, and the axial direction of the second connecting holes 13 is parallel to the radial direction of the cigarette dividing drum 2. The flange 3 is further provided with a plurality of third connecting holes 31 and fourth connecting holes 33. The axial direction of the third connecting holes 31 is parallel to the axial direction of the cigarette dividing drum 2, and the third connecting holes 31 are arranged on the side (i.e. the front side) of the flange 3 away from the cigarette dividing drum 2. The flange 3 is further provided with a first protruding portion 32 at the end (i.e. the rear end) close to the cigarette dividing drum 2, and the fourth connecting holes 33 are arranged on the first protruding portion 32 and have an axial direction parallel to the radial direction of the cigarette dividing drum 2. The front end of the cigarette dividing drum 2 is provided with a first clamping groove 27, and the flange 3 and the end cover 1 are sequentially arranged on the first clamping groove 27 from inside to outside. The first clamping groove 27 is provided with a sixth connecting hole 26 and a fifth connecting hole 25. The fifth connecting hole 25 is connected with the first connecting hole 12 by a bolt, the sixth connecting hole 26 is connected with the third connecting hole 31 by a bolt, and the fourth connecting hole 33 is connected with the second connecting hole 13 by a bolt. In this way, the relative fixation between the cigarette dividing drum 2, the end cover 1 and the flange 3 is achieved.

[0043] In addition to the above-mentioned detachable connection by bolt fastening, other ways can also be selected by those skilled in the art, such as the clamping connection between the clamping groove and the buckle.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
