[0027] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0028] Example 1

[0029] As introduced in the background technology, by analyzing the problems existing in the cleaning of the suction ribbon roller, it is concluded that the main problem is that the cleaning scraper cannot effectively clean the dirt in the grid groove of the suction ribbon roller. Based on this, this embodiment proposes a new type of cigarette machine suction ribbon roller cleaning device, which can effectively clean the suction ribbon roller and make it clean and free of dirt.

[0030] like Figure 2 As shown, in one embodiment of the utility model, a device for cleaning the roller of the suction belt 6 of a cigarette making machine is proposed. The cigarette making machine has a cover shell 1, and a roller for driving the suction belt 6 to move is arranged in the cover shell 1. The circumferential surface of the roller is provided with a groove, and the two sides of the groove are positioning edges, and the bottom surface of the groove is a grid groove.

[0031] The cleaning device includes a transmission shaft 3 and a roller brush 2. The transmission shaft 3 is arranged on the cover shell 1. The roller brush 2 is installed at the end of the transmission shaft 3. The roller brush 2 is embedded in the groove of the roller, and the rotation direction of the roller brush 2 is the same as the rotation direction of the roller. The outer cylindrical surface of the roller brush 2 has bristles. The side surfaces of the bristles are located between the two positioning edges, and the outer ends of the bristles have a predetermined compression amount with the grid groove.

[0032] In this embodiment, by adding a transmission shaft 3 and a roller brush 2, the transmission shaft 3 drives the roller brush 2 to rotate on the groove of the roller. The roller brush 2 cleans the grid groove and the side through friction, so that the grid groove surface of the suction ribbon 6 roller remains clean, reducing the slippage of the suction ribbon 6 during operation. Moreover, the bristles of the roller brush 2 can penetrate into the grid groove, and at the same time, there is a certain amount of compression between the bristles and the groove of the cleaned roller, so as to achieve a thorough cleaning effect without dead angles. Furthermore, the roller brush 2 has the same rotation direction as the roller, so the roller brush 2 and the roller move in opposite directions at the contact point, which makes it easier to clean dirt and more thoroughly, avoids the accumulation of dirt on the roller surface, reduces the slippage of the suction ribbon 6, ensures the stable transportation of the tobacco bundle, reduces defective products and ensures product quality.

[0033] like Figure 2 As shown, the roller wheel includes a driving wheel 5 and a driven wheel 4, and the suction belt 6 moves around the driving wheel 5 and the driven wheel 4 in sequence. Since there is a suction belt 6 between the driving wheel 5 and the driven wheel 4, the transmission shaft 3 and the roller brush 2 are set in two groups, each group includes a transmission shaft 3 and a roller brush 2, and the roller brush 2 is divided into a first roller brush and a second roller brush, the first roller brush is embedded in the driving wheel 5, and the second roller brush is embedded in the driven wheel 4. Among them, the first roller brush has the same rotation direction as the driving wheel 5, the second roller brush has the same rotation direction as the driven wheel 4, and the first roller brush and the second roller brush have opposite rotation directions. The driving wheel 5 and the driven wheel 4 are cleaned respectively by two first roller brushes and second roller brushes with opposite rotation directions, so as to ensure the cleaning state of the two rollers and prevent the suction belt 6 from slipping.

[0034] The housing 1 has an air chamber 7, and the roller is arranged in the air chamber 7 of the housing 1. Specifically, the housing 1 includes a side plate and an outer contour plate, and the side plate and the outer contour plate enclose the air chamber 7 for accommodating the roller, the first end of the transmission shaft 3 is mounted on the side plate of the housing 1, and the roller brush 2 is mounted on the second end of the transmission shaft 3. A negative pressure air suction port 8 is arranged on the side plate of the housing 1, and the negative pressure air suction port 8 is connected to the air chamber 7 of the housing 1. When the roller brush 2 rotates, the roller brush 2 cleans the grid groove and the side of the roller by friction, and because the negative pressure in the air chamber 7 is very large, the dirt such as tobacco dust that is cleaned and falls can be sucked away by the negative pressure air suction port 8 in the air chamber 7 in time to keep it clean.

[0035] The first end of the transmission shaft 3 extends out of the side plate of the housing 1 and is driven by a servo motor or by the power system of the cigarette making machine. The bristles of the roller brush 2 are made of nylon. The compression amount between the outer end of the bristles and the grid groove is 1mm-3mm, for example, the compression amount is 2mm.

[0036] In this embodiment, the roller brush 2 is made of nylon material, which has good wear resistance and elasticity and will not damage the roller surface. The compression amount between the roller brush 2 and the surface to be cleaned is 2 mm, ensuring the cleaning effect.

[0037] Working process: The roller drives the suction belt 6 to move through friction, and the roller brush 2 rotates at the same time. The roller brush 2 cleans the grid groove and the side through friction, and the fallen smoke and dust are sucked away by the negative pressure suction port 8 in the wind chamber 7.

[0038] Example 2

[0039] Based on Example 1, this example provides a specific installation method for the roller brush 2: the cleaning device further includes a pneumatic locking assembly 9, which is installed at the end of the transmission shaft 3 and is used to install the roller brush 2. Figure 3 , Figure 4 As shown, the pneumatic locking device includes a cylinder 91, a mounting seat 94, a piston 92 rod and a slider 93. The mounting seat 94 is arranged at the end of the cylinder 91. The piston 92 rod is installed in the cylinder 91 to form a cylinder. The outer end of the piston 92 rod is a frustum. Slide grooves are arranged on both sides of the mounting seat 94. The slider 93 is slidably installed in the slide groove, and both the inner and outer sides of the slider 93 are inclined surfaces. Figure 5 As shown, the roller brush 2 includes a roller 21, and bristles (not shown in the figure) are arranged on the outer periphery of the roller 21. One end of the roller 21 has a mounting hole, and both sides of the mounting hole have slots 22. The slots 22 are oblique slots, and the mounting hole is sleeved on the mounting seat 94, and the slider 93 can be snapped into the slot 22 of the roller 21.

[0040] When in use, the roller brush 2 is sleeved on the mounting seat 94, and the piston 92 rod moves downward under the action of air pressure, and the sliders 93 on both sides are pushed outward through the cone to be clamped in the clamping groove 22 of the roller brush 2, thereby fixing the roller brush 2. When replacing the roller brush 2, the piston 92 rod moves upward under the action of air pressure, and the roller brush 2 is pulled outward along the axis. Since the bristles have a certain flexibility, they can be pulled out along the axis. Under the action of the inclined surface, the sliders 93 on both sides slide inward to remove the roller brush 2. The setting of the pneumatic locking assembly 9 facilitates the replacement of the roller brush 2, ensures a stable connection, and shortens the replacement time.

[0043] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
