Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, specifically to an acceleration wheel assembly applied to hollow filter rods. Background Technology

[0002] With the development of the tobacco industry, consumers' personalized needs have driven the development of unique and complex filter rods, and various forms of specialized filter rod products have gradually emerged in cigarette products. Among them, compared with traditional solid filter rods, hollow filter rods have appeared, and hollow and solid filter rods are combined to form a complete filter tip.

[0003] When transferring solid filter rods, two acceleration wheels arranged side by side are needed to separate the front and rear filter rods. Since the two acceleration wheels can only accelerate the filter rods after clamping the solid rods, when the filter rods are hollow, the two acceleration wheels cannot clamp the hollow filter rods, thus failing to effectively accelerate the hollow filter rods. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides an acceleration wheel assembly for hollow filter rods, with the aim of accelerating the hollow filter rods.

[0005] An accelerating wheel assembly for hollow filter rods includes two accelerating wheels arranged side by side. The circumferential surfaces of the two accelerating wheels are provided with arc-shaped grooves, forming a transmission channel for transporting the hollow filter rods between the arc-shaped grooves. The accelerating wheel has an annular disc structure. A first channel connecting its outer and inner rings is evenly arranged around its circumference within the accelerating wheel. A second channel is provided at the inner ring of the accelerating wheel. The inner end of the second channel is attached to the inner ring of the accelerating wheel and corresponds vertically to the transmission channel. When the accelerating wheel rotates, at least one inner end of the first channel corresponds to and connects with the inner end of the second channel. The outer end of the second channel is connected to a negative pressure source, generating a negative pressure at the outer end of the first channel within the transmission channel, which is used to adsorb the hollow filter rods located within the transmission channel.

[0006] Furthermore, a groove is formed within the arc-shaped groove at a position between two adjacent outer ports of the first channel, and the groove is connected to the outer port of the first channel located at the front position in the transmission direction.

[0007] Furthermore, the groove is strip-shaped, and the outer end port of the first channel is located at the end of the groove.

[0008] Furthermore, the inner ring of the acceleration wheel is fitted with a fixed sleeve and is in contact with it, the second channel is located inside the side wall of the fixed sleeve, and the inner end port of the second channel is located on the outer ring of the fixed sleeve.

[0009] Furthermore, the acceleration wheel is sleeved on the right end of the fixed sleeve, and the outer end of the second channel is located on the left end of the fixed sleeve; a connecting plate is fixedly connected to the acceleration wheel at the position corresponding to the right end face of the fixed sleeve, and the drive shaft is fixedly connected to the connecting plate.

[0010] Furthermore, the connecting plate and the acceleration wheel are integrated into one unit.

[0011] Furthermore, the fixed sleeve includes a first cylinder and a second cylinder. The middle part of the second channel forms a first chamber and a second chamber in the first cylinder and the second cylinder, respectively, thereby leading the outer end port of the second channel to the side of the fixed sleeve.

[0012] Furthermore, the drive shaft passes through the fixed sleeve, and a bearing is rotatably mounted between the two.

[0013] Furthermore, the fixed sleeve is fixedly connected to the fixed frame, and a servo motor is fixedly installed on the fixed frame. The output shaft of the servo motor is fixedly connected to the drive shaft through a coupling.

[0014] The beneficial effects of this utility model are as follows: By forming a negative pressure adsorption structure in the transmission channel formed by the second channel and the two acceleration wheels, the problem of not being able to accelerate the hollow filter rod by clamping is solved. The hollow filter rod can be effectively and consistently accelerated by adsorption, which meets industrial needs. Attached Figure Description

[0020] An acceleration wheel assembly applied to hollow filter rods, such as Figure 1 and Figure 2 As shown, it includes two parallel accelerating wheels 1, each with an arc-shaped groove 11 on its circumferential surface. The diameter of the arc-shaped groove 11 is 0.2mm to 1mm larger than the diameter of the hollow filter rod 4. A transmission channel for transmitting the hollow filter rod 4 is formed between the arc-shaped grooves 11 of the two accelerating wheels 1. Figure 3 As shown, the acceleration wheel 1 has an annular disc structure. A first channel 12 connecting the outer and inner rings is evenly arranged around the circumference of the acceleration wheel 1. A second channel 24 is provided at the inner ring of the acceleration wheel 1. The inner end port of the second channel 24 is attached to the inner ring of the acceleration wheel 1 and corresponds vertically to the transmission channel. When the acceleration wheel 1 rotates, at least one inner end port of the first channel 12 corresponds to and is connected to the inner end port 243 of the second channel 24. The outer end port of the second channel 24 is connected to a negative pressure source, which generates a negative pressure at the outer end port of the first channel 12 located in the transmission channel and is used to adsorb the hollow filter rod 4 located in the transmission channel. To facilitate the amplification of the adsorption effect of the outer end port of the first channel 12 on the hollow filter rod 4, a groove 13 is provided in the arc-shaped groove 11 between two adjacent outer end ports of the first channel 12. The groove 13 is connected to the outer end port of the first channel 12 located in the forward position in the transmission direction. When the outer end port of the first channel 12 is close to the hollow filter rod 4, the hollow filter rod 4 can be adsorbed by the groove 13. The groove 13 is strip-shaped, and the outer end port of the first channel 12 is located at the end of the groove 13, which can improve the overall adsorption effect of the transmission channel on the hollow filter rod 4 and help to increase the speed of the acceleration wheel 1.

[0021] Specifically, to facilitate the setting of a second channel 24 at the inner ring of the acceleration wheel 1, a fixing sleeve 2 is fitted and attached to the inner ring of the acceleration wheel 1. The second channel 24 is located inside the side wall of the fixing sleeve 2, and the inner end port 243 of the second channel 24 is located on the outer ring of the fixing sleeve 2. To facilitate driving the acceleration wheel 1, the acceleration wheel 1 is fitted onto the right end of the fixing sleeve 2, and the outer end port of the second channel 24 is located on the left end of the fixing sleeve 2. Figure 4 As shown, a connecting plate 7 is fixedly connected to the acceleration wheel 1 at the position corresponding to the right end face of the fixed sleeve 2. The connecting plate 7 is integrated with the acceleration wheel 1. The drive shaft 6 is fixedly connected to the connecting plate 7 and drives the acceleration wheel 1 through the connecting plate 7.

[0022] To achieve a compact design between the drive shaft 6 and the fixed sleeve 2, the drive shaft 6 passes through the fixed sleeve 2, and a bearing 5 is rotatably mounted between them, thereby improving the stability of the drive shaft 6 within the fixed sleeve 2. The fixed sleeve 2 is fixedly connected to a fixed frame 21, on which a servo motor 3 is fixedly mounted. The output shaft of the servo motor 3 is fixedly connected to the drive shaft 6 via a coupling 32. Furthermore, the fixed sleeve 2 includes a first cylindrical body 22 and a second cylindrical body 23. The middle portion of the second channel 24 forms a first chamber 241 and a second chamber 242 within the first cylindrical body 22 and the second cylindrical body 23, respectively, thereby leading the outer end of the second channel 24 to the side of the fixed sleeve 2, facilitating the horizontal arrangement of the quick-connect fittings for the negative pressure pipeline.

[0023] In use, after connecting the second channel 24 to an external negative pressure source, the continuous hollow filter rods 4 are sent into the transmission channel. The outer end port of the first channel 12 adsorbs the hollow filter rods 4, and the acceleration wheel 1 accelerates the hollow filter rods 4 so that they create a gap with the subsequent hollow filter rods 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
