Description

Technical Field

[0001] The present invention relates to the field of cigarette manufacturing, and more particularly, to a cleaning device for an inner lining paper embossing roller. Background Art

[0002] The inner lining paper is a composite material of aluminum foil and paper, and is used to wrap the formed cigarette rods during the cigarette manufacturing process. Before entering the cutting device, the inner lining paper needs to be rolled by an embossing roller, and the reticulate pattern formed on the inner lining paper after rolling can make the inner lining paper softer, thereby improving the folding smoothness and folding quality during the wrapping and folding process.

[0003] Due to the large amount of tobacco dust in the working environment and the dust carried on the inner lining paper, the reticulate pattern of the embossing roller is prone to sticking dirt, resulting in unqualified embossing quality. In order to ensure the embossing quality, it is necessary to clean the embossing roller.

[0004] The existing method for cleaning the embossing roller requires first disassembling the embossing roller, soaking it with alcohol, and then cleaning the dirt with a copper brush. Not only is the workload large and the labor intensity high, but also the parallelism and clearance between the rollers need to be adjusted when reinstalling the embossing roller, and the installation and adjustment are extremely troublesome.

[0005] Therefore, how to provide a cleaning device that can clean the inner lining paper embossing roller in a time-saving and labor-saving manner has become a technical problem that needs to be solved urgently in this field. Summary of the Invention

Detailed implementation manners

[0032] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and in no way limits the present invention, its application, or its use.

[0034] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and devices should be regarded as part of the specification.

[0035] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0036] As Figures 1 to 4 shown, the inner - lining - paper embossing - roller cleaning device of the present disclosure includes a first brush mechanism, a first dirt - removing mechanism, a second brush mechanism, and a second dirt - removing mechanism.

[0037] The first brush mechanism includes a brush shaft 1, a brush sleeve 2, and a brush - shaft drive unit 3. The brush sleeve 2 is sleeved outside the brush shaft 1, and the brush sleeve 2 is provided with first bristles 22. The first bristles 22 are generally evenly distributed along the circumferential direction of the brush sleeve 2. The first bristles 22 are in contact with the outer surface of the active embossing roller 01, so that the dirt on the active embossing roller 01 can be brushed off. The brush - shaft drive unit 3 can be used to drive the brush shaft 1 to drive the brush sleeve 2 to rotate in the same direction as the rotation direction of the active embossing roller 01. The brush - shaft drive unit 3 can be, for example, a motor, etc. Driving the brush shaft 1 to rotate in the same direction as the rotation direction of the active embossing roller 01 is beneficial to reducing the wear rate of the first bristles 22.

[0038] The first dirt - removing mechanism is located downstream of the first brush mechanism along the rotation direction of the active embossing roller 01, so that the same surface of the active embossing roller 01 first passes through the first brush mechanism and then through the first dirt - removing mechanism. As Figure 1As shown by the arrow in the figure, the active embossing roller 01 on the left rotates in the clockwise direction, and the driven embossing roller 02 on the right rotates in the counterclockwise direction. The lining paper 03 passes between the active embossing roller 01 and the driven embossing roller 02. As the active embossing roller 01 rotates, the surface of the active embossing roller 01 first passes through the first brush mechanism and then through the first dirt removal mechanism.

[0039] The first dirt removal mechanism includes an air suction chamber 4 and an air suction unit (not shown in the figure). The air suction chamber 4 includes a dirt retaining plate 41 and an air suction groove 42. The dirt retaining plate 41 is an arc-shaped plate, and the dirt retaining plate 41 is adapted to the outer surface of the active embossing roller 01. That is to say, the dirt retaining plate 41 can cover a certain area of the surface of the active embossing roller 01, but the dirt retaining plate 41 does not directly contact the surface of the active embossing roller 01. The dirt retaining plate 41 can block the dirt scattered from the active embossing roller 01 by the first brush mechanism and direct these dirt to the air suction groove 42. Specifically in implementation, the surface area of the active embossing roller 01 covered by the dirt retaining plate 41 is 5%-10% of the lateral surface area of the active embossing roller 01 to more effectively direct the dirt to the air suction groove 42.

[0040] The air suction groove 42 is located on the side of the dirt retaining plate 41 adjacent to the first brush mechanism. The air suction groove 42 is provided with air suction holes 4220. The dirt directly brushed off the active embossing roller 01 by the first brush mechanism and the dirt led out by the dirt retaining plate 41 can be sucked into the air suction chamber 4 through the air suction holes 4220.

[0041] The air suction unit can be used to pump air out of the air suction chamber 4 so that the air suction chamber 4 sucks the dirt brushed off the active embossing roller 01 by the first brush mechanism through the air suction holes 4220. The air suction unit can be, for example, an air extraction pump or the like.

[0042] The second brush mechanism includes a brush 5 and a brush fixing bracket (not shown in the figure). The brush 5 is in contact with the outer surface of the driven embossing roller 02, and the brush 5 is installed on the brush fixing bracket. The brush 5 is fixed on the brush fixing bracket, and the brush 5 can usually only swing slightly driven by the driven embossing roller 02 and cannot move actively. Since the dirt on the driven embossing roller 02 is usually less and the dirt on the driven embossing roller 02 is easier to remove than the dirt on the active embossing roller 01, the brush 5 that cannot move actively can effectively clean the dirt on the driven embossing roller 02.

[0043] The second dirt removal mechanism can be used to remove the dirt brushed off the driven embossing roller 02 by the second brush mechanism. The second dirt removal mechanism can be, for example, an air suction mechanism that can suck away the dirt brushed off the driven embossing roller 02, or the second dirt removal mechanism can be, for example, a collection bag that can collect the dirt.

[0044] The embossed paper liner cleaning device of the present disclosure is directed at the characteristics of dirt on the active embossing roller 01 and the driven embossing roller 02, and removes the dirt on the embossing rollers through the first brush mechanism and the first dirt removal mechanism with different structures, as well as the second brush mechanism and the second dirt removal mechanism, while improving the cleaning effect and reducing the cost.

[0045] The embossed paper liner roller cleaning device of the present disclosure can clean the active embossing roller 01 through the first brush mechanism and the first dirt removal mechanism, and remove the dirt on the driven embossing roller 02 through the second brush mechanism and the second dirt removal mechanism, thereby efficiently and thoroughly cleaning the embossed paper liner roller.

[0046] In an embodiment of the embossed paper liner roller cleaning device of the present disclosure, the brush shaft 1 is an eccentric shaft. The eccentric shaft structure of the brush shaft 1 is beneficial to adjusting the distance between the first bristles 22 and the active embossing roller 01 by rotating the brush shaft 1 after the first bristles 22 are worn, so as to ensure good contact between the first bristles 22 and the active embossing roller 01.

[0047] In an embodiment of the embossed paper liner roller cleaning device of the present disclosure, the brush sleeve 2 includes a brush sleeve body 21 and first bristles 22. The ratio of the length of the first bristles 22 to the distance between the brush sleeve body 21 and the outer surface of the active embossing roller 01 is (1.05 - 1.1):1. This ratio of the length of the first bristles 22 to the distance between the brush sleeve body 21 and the outer surface of the active embossing roller 01 is beneficial to ensuring the cleaning effect while not affecting the normal rotation of the active embossing roller 01 and avoiding interfering with the embossing effect on the paper liner 03.

[0048] In an embodiment of the embossed paper liner roller cleaning device of the present disclosure, in order to avoid affecting the rotation of the active embossing roller 01, the ratio of the rotation speed of the brush shaft 1 to the rotation speed of the active embossing roller 01 is (0.85 - 0.95):1.

[0049] In an embodiment of the embossed paper liner roller cleaning device of the present disclosure, in order to improve the efficiency of sucking dirt, the included angle between the suction direction of the suction holes 4220 and the tangent of the outer surface of the active embossing roller 01 is less than or equal to 45°.

[0050] In an embodiment of the inner liner paper embossing roll cleaning device of the present disclosure, the air suction groove 42 includes a wind baffle 421 and an air suction plate 422. There is an included angle between the wind baffle 421 and the air suction plate 422. The wind baffle 421 extends in a direction away from the active embossing roll 01 from the side of the dirt blocking plate 41 adjacent to the first brush mechanism. The air suction plate 422 extends in a direction towards the first bristles 22 from the side of the wind baffle 421 away from the active embossing roll 01. The air suction holes 4220 are only located on the air suction plate 422. The setting of the wind baffle 421 is beneficial to form a greater negative pressure at the air suction groove 42, so as to clean the active embossing roll 01 more thoroughly, especially the dirt that has been brushed off the surface of the active embossing roll 01 but is adsorbed back onto the active embossing roll 01, and the dirt that is loose on the surface of the active embossing roll 01 but has not been completely brushed off.

[0051] Further, in order to improve the cleaning efficiency, the included angle between the wind baffle 421 and the air suction plate 422 is an acute angle, the included angle between the wind baffle 421 and the tangent plane of the outer surface of the active embossing roll 01 is an acute angle, and the included angle between the wind baffle 421 and the air suction plate 422 is greater than the included angle between the wind baffle 421 and the tangent plane of the outer surface of the active embossing roll 01. The tangent plane of the outer surface of the above-mentioned active embossing roll 01 refers to the tangent plane on the active embossing roll 01 closest to the wind baffle 421.

[0052] Further, in order to improve the cleaning efficiency, the ratio of the distance between the dirt blocking plate 41 and the active embossing roll 01 to the diameter of the active embossing roll 01 is 1:(20 - 60). The ratio of the distance between the edge of the air suction plate 422 and the first bristles 22 to the length of the first bristles 22 is 1:(2 - 4). The distance between the edge of the air suction plate 422 and the first bristles 22 refers to the shortest distance between the air suction plate 422 and the first bristles 22.

[0053] In an embodiment of the inner liner paper embossing roll cleaning device of the present disclosure, the brush 5 has a single row of second bristles or multiple rows of parallel second bristles, and the included angle between the second bristles and the tangent plane of the outer surface of the driven embossing roll 02 is an obtuse angle. The tangent plane of the outer surface of the above-mentioned driven embossing roll 02 refers to the tangent plane at the position where the second bristles are in contact with the surface of the driven embossing roll 02. The included angle between the second bristles and the tangent plane of the outer surface of the driven embossing roll 02 being an obtuse angle is beneficial to more efficiently brush the dirt on the driven embossing roll 02.

[0054] The second dirt removal mechanism includes a dirt collecting hopper 6. The dirt collecting hopper 6 is provided with a dirt collecting port (not shown in the figure) for collecting the dirt brushed off the driven embossing roll 02 by the second brush mechanism. The dirt collecting hopper 6 is located upstream of the second brush mechanism along the rotation direction of the driven embossing roll 02, so that the same surface position on the driven embossing roll 02 first passes through the second brush mechanism and then passes through the second dirt removal mechanism. As Figure 1As shown by the arrow in , the driven embossing roller 02 on the right rotates counterclockwise, and the driving embossing roller 01 on the left rotates clockwise. The inner liner paper 03 passes between the driving embossing roller 01 and the driven embossing roller 02. As the driven embossing roller 02 is driven to rotate by the inner liner paper 03, the surface of the driven embossing roller 02 first passes through the second brush mechanism and then through the second dirt removal mechanism. Due to the setting that the angle between the second bristles and the tangent plane of the outer surface of the driven embossing roller 02 is an obtuse angle, the dirt brushed off from the driven embossing roller 02 by the second bristles slides along the surface of the driven embossing roller 02 into the dirt collection hopper 6.

[0055] In specific implementation, an air suction mechanism may also be provided in the dirt collection hopper 6 to more efficiently suck the dirt into the dirt collection hopper 6.

[0056] Furthermore, the contact position of the brush 5 with the outer surface of the driven embossing roller 02 is located on the side of the driven embossing roller 02 away from the driving embossing roller 01. The side of the driven embossing roller 02 away from the driving embossing roller 01 refers to the side away from the driving embossing roller 01 of the interface parallel to the tangent plane that is tangent to both the driving embossing roller 01 and the driven embossing roller 02 and is located between the driving embossing roller 01 and the driven embossing roller 02, and the central axis of the driven embossing roller 02 is located on this interface.

[0057] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for the purpose of illustration and not for the purpose of limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
