Detailed Description of the Embodiments

[0033] 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 values set forth in these embodiments do not limit the scope of the present invention.

[0034] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present invention or its application or use.

[0035] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0036] In all examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0037] As Figures 1 to 4 shown, the inner liner paper embossing roll cleaning device of the present disclosure includes a brush mechanism, a vibration mechanism, and a dirt removal mechanism.

[0038] The brush mechanism includes a brush shaft 1 and a brush sleeve 2. The brush sleeve 2 is sleeved outside the brush shaft 1, and bristles 22 are provided on the brush sleeve 2. The bristles 22 are generally evenly distributed along the circumferential direction of the brush sleeve 2. The bristles 22 are in contact with the outer surface of the embossing roll. Through the contact between the bristles 22 and the outer surface of the embossing roll, the dirt on the embossing roll can be brushed off.

[0039] The vibration mechanism can be used to drive the brush mechanism to vibrate in the tangential direction with respect to the outer surface of the embossing roll. The vibration mechanism can be, for example, a mechanical vibration mechanism or an ultrasonic vibration mechanism. The setting of the vibration mechanism is conducive to the brush mechanism more efficiently brushing off the dirt on the embossing roll.

[0040] The dirt removal mechanism is located downstream of the brush mechanism along the rotation direction of the embossing roll, so that the same surface of the embossing roll first passes through the brush mechanism and then through the dirt removal mechanism. As Figure 1 shown by the arrows in, the embossing roll on the left rotates clockwise, the embossing roll on the right rotates counterclockwise, and the inner liner paper 01 passes through the middle of the embossing rolls on the left and right. As the embossing roll on the left rotates, the surface of the embossing roll first passes through the brush mechanism and then through the dirt removal mechanism.

[0041] The dirt removal mechanism includes a suction chamber 7 and a suction unit (not shown in the figure). The suction chamber 7 includes a dirt retaining plate 71 and a suction groove 72. The dirt retaining plate 71 is an arc-shaped plate, and the dirt retaining plate 71 is adapted to the outer surface of the embossing roller. That is to say, the dirt retaining plate 71 can cover a certain area of the surface of the embossing roller, but the dirt retaining plate 71 does not directly contact the surface of the embossing roller. The dirt retaining plate 71 can block the dirt scattered by the brush mechanism from being brushed off the embossing roller and direct this dirt to the suction groove 72. Specifically in implementation, the surface area of the embossing roller covered by the dirt retaining plate 71 is 5%-10% of the surface area of the side surface of the embossing roller, so as to more effectively direct the dirt to the suction groove 72.

[0042] The suction groove 72 is located on the side of the dirt retaining plate 71 adjacent to the brush mechanism. Suction holes 7220 are provided in the suction groove 72. The dirt directly brushed off the embossing roller by the brush mechanism and the dirt led out by the dirt retaining plate 71 can be sucked into the suction chamber 7 through the suction holes 7220.

[0043] The suction unit can be used to pump air out of the suction chamber 7, so that the suction chamber 7 sucks the dirt brushed off the embossing roller by the brush mechanism through the suction holes 7220. The suction unit can be, for example, an air extraction pump or the like.

[0044] The inner liner paper embossing roller cleaning device of the present disclosure can brush off the dirt on the embossing roller through the brush mechanism driven by the vibration mechanism, and suck away the brushed-off dirt through the dirt removal mechanism, thereby cleaning the inner liner paper embossing roller in a time-saving and labor-saving manner.

[0045] In an embodiment of the inner liner paper embossing 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 bristles 22 and the embossing roller by rotating the brush shaft 1 after the bristles 22 are worn, so as to ensure good contact between the bristles 22 and the embossing roller.

[0046] In an embodiment of the inner liner paper embossing roller cleaning device of the present disclosure, the brush sleeve 2 includes a brush sleeve body 21 and bristles 22. The ratio of the length of the bristles 22 to the distance between the brush sleeve body 21 and the outer surface of the embossing roller is (1.05 - 1.1):1. This ratio of the length of the bristles 22 to the distance between the brush sleeve body 21 and the outer surface of the embossing roller is beneficial to ensuring the cleaning effect while not affecting the normal rotation of the embossing roller and avoiding interfering with the embossing effect on the inner liner paper 01.

[0047] In an embodiment of the inner liner paper embossing roller cleaning device of the present disclosure, in order to improve the cleaning efficiency of the brush mechanism on the embossing roller while avoiding abnormal wear of the bristles 22, the ratio of the vibration frequency of the brush mechanism to the rotation speed of the embossing roller is (2 - 4):1. The unit of the vibration frequency of the brush mechanism is Hz, and the unit of the rotation speed of the embossing roller is cm / s.

[0048] In an embodiment of the inner liner paper embossing roll cleaning device of the present disclosure, the vibration mechanism includes a horn 3, a piezoelectric ceramic sheet 4, an end cap 5, and a fixing member 6. The fixing member 6 can be, for example, a bolt. The horn 3 is connected to the brush shaft 1. The horn 3 can be connected to the brush shaft 1 by means of fitting or the like. The piezoelectric ceramic sheet 4 is located at the end of the horn 3. The number of the piezoelectric ceramic sheets 4 can be flexibly set according to actual needs. The end cap 5 is located on the side of the piezoelectric ceramic sheet 4 away from the horn 3. The fixing member 6 can press and fix the end cap 5 on the horn 3. The piezoelectric ceramic sheet 4 can be fixed on the horn 3 by the fixing member 6.

[0049] The vibration mechanism in this embodiment has a simple structure and can conveniently and effectively realize the vibration of the brush mechanism.

[0050] In an embodiment of the inner liner paper embossing roll 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 hole 7220 and the tangent of the outer surface of the embossing roll is less than or equal to 45°.

[0051] In an embodiment of the inner liner paper embossing roll cleaning device of the present disclosure, the suction slot 72 includes a wind blocking plate 721 and a suction plate 722. There is an included angle between the wind blocking plate 721 and the suction plate 722. The wind blocking plate 721 extends from the side of the dirt blocking plate 71 adjacent to the brush mechanism in a direction away from the embossing roll. The suction plate 722 extends from the side of the wind blocking plate 721 away from the embossing roll in the direction of the brush bristles 22. The suction holes 7220 are only located on the suction plate 722. The setting of the wind blocking plate 721 is beneficial to forming a greater negative pressure at the suction slot 72, so as to clean the embossing roll more thoroughly, especially the dirt that has been brushed off but adsorbed back onto the embossing roll on the surface of the embossing roll and the dirt that is loose but not completely brushed off on the surface of the embossing roll.

[0052] Furthermore, in order to improve the cleaning efficiency, the included angle between the wind blocking plate 721 and the suction plate 722 is an acute angle, the included angle between the wind blocking plate 721 and the tangent plane of the outer surface of the embossing roll is an acute angle, and the included angle between the wind blocking plate 721 and the suction plate 722 is greater than the included angle between the wind blocking plate 721 and the tangent plane of the outer surface of the embossing roll. The tangent plane of the outer surface of the above-mentioned embossing roll refers to the tangent plane on the embossing roll closest to the wind blocking plate 721.

[0053] Furthermore, in order to improve the cleaning efficiency, the ratio of the distance between the dirt blocking plate 71 and the embossing roll to the diameter of the embossing roll is 1:(20 - 60). The ratio of the distance between the edge of the suction plate 722 and the brush bristles 22 to the length of the brush bristles 22 is 1:(2 - 4). The distance between the edge of the suction plate 722 and the brush bristles 22 refers to the shortest distance between the suction plate 722 and the brush bristles 22.

[0054] The present disclosure also provides an inner lining paper embossing system, including a driving embossing roller 8, a driven embossing roller 9, and the inner lining paper embossing roller cleaning device of the present disclosure. The inner lining paper embossing roller cleaning device is correspondingly arranged with the driving embossing roller 8.

[0055] During specific implementation, the brush mechanism of the inner lining paper embossing roller cleaning device only vibrates relative to the tangential direction of the outer surface of the embossing roller under the drive of the vibration mechanism, and will not make an active rotational motion. In this case, the brush mechanism can only make a rotational motion driven by the driving embossing roller 8. This setting is beneficial to avoid excessive wear of the bristles 22 and / or the embossing roller.

[0056] In addition, since there is more and more stubborn dirt accumulated on the driving embossing roller 8, setting the inner lining paper embossing roller cleaning device to only clean the driving embossing roller 8 is beneficial to controlling the cost while effectively cleaning the embossing roller.

[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 illustration and not for 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.
