[0003] In the existing cigarette box production process, the outermost transparent film is an important part of improving the appearance quality of the cigarette box. The transparent film needs to have the characteristics of high brightness and low haze to highlight the quality of the cigarette, and the production of the transparent film involves multiple processes such as batching, extrusion, casting, vertical drawing, horizontal drawing and winding, which together ensure the optical performance and physical properties of the transparent film to meet the specific requirements of the cigarette packaging.

Since the thickness, width and length of the material change, the tension changes, and therefore the existing tensioning method cannot adapt to these changes, resulting in poor tension adjustment of the top of the transparent film. Therefore, the application provides a cigarette box tensioning mechanism. CONTENT OF THE INVENTION

[0037] In use, firstly, the servo motor 5 is started to drive the rotating shaft 4 to rotate, with the continuous rotation of the rotating shaft 4, the two bevel gears one 6 at both ends are driven to rotate together, due to the meshing between the two bevel gears one 6 and the two bevel gears two 9, with the rotation of the two bevel gears one 6, the two bevel gears two 9 are driven to rotate together, at this time, through the rotation of the two bevel gears two 9, the two lead screws 8 are driven to move continuously, thus through the guidance of the two moving blocks 10, the tensioning roller 12 is driven to move in the fixed frame 1, so as to adjust the position of the tensioning roller 12 in real time according to the tension of the film, through the change of the position of the tensioning roller 12, the tension change of the film material can be effectively balanced, wrinkles can be prevented from being generated, thus product deformation and film tearing can be avoided, and the processing precision is greatly improved.

[0038] With reference to Figure 1 and Figure 3The cleaning assembly comprises two fixed blocks 13 fixedly connected on the top of the two moving blocks 10, a sliding plate 14 slidably connected in the two sliding grooves, a cleaning brush 15 clamped on the bottom of the sliding plate 14, a buckle assembly symmetrically arranged on the top of the cleaning brush 15, a guide rod 16 fixedly connected in the sliding groove on one side of the two fixed blocks 13, the two ends of the sliding plate 14 slidably connected on the two guide rods 16, and a spring 17 sleeved on the outer wall of the two guide rods 16.

[0039] In use, since the tensioning roller 12 is attached to the upper side of the film, the tensioning roller 12 will slightly rotate with the movement of the film, so that the outer wall of the tensioning roller 12 is in contact with the cleaning brush 15 in a circulating manner. The spring 17 is always elastically pressed against the sliding plate 14, so that the sliding plate 14 pushes the cleaning brush 15 to be arranged above the tensioning roller 12, and the cleaning brush 15 can always wipe and clean the outer wall of the tensioning roller 12, so that the dust adhered to the tensioning roller 12 is cleaned, the tensioning roller 12 is kept clean, and the working efficiency is improved, so as not to affect the normal production.

[0040] Referring to Figure 3 and Figure 4 The buckle assembly comprises a clamping block 18 fixedly connected on the top of the cleaning brush 15, two clamping grooves 19 penetratingly arranged on the sliding plate 14, a recess 20 formed on the two sides of the clamping block 18, a spring 21 fixedly connected in the recess 20, a sliding block 22 slidably connected in the recess 20, and the end of the spring 21 fixedly connected with the end of the sliding block 22. The shape and size of the clamping groove 19 are consistent with those of the clamping block 18, and the end of the sliding block 22 away from the spring 21 is arc-shaped.

[0041] In use, if the cleaning brush 15 needs to be replaced, the arc-shaped end of the sliding block 22 can be manually pressed to be pressed into the recess 20, so that the sliding block 22 is separated from the top surface of the sliding plate 14. At this time, the sliding plate 14 can be pulled upward on the guide rod 16, and the clamping block 18 can be pulled out of the clamping groove 19, so that the cleaning brush 15 can be replaced.

[0042] Referring to Figure 1 and Figure 2The bottom of each of the plurality of supporting legs 3 is fixedly connected with an anti-skid pad 24.

[0043] In use, the anti-skid pad 24 can keep the stability between the fixing frame 1 and the ground, preventing the fixing frame 1 from being displaced in use.

[0044] The implementation principle of the cigarette box tensioning mechanism is as follows: in use, first, the produced film is transmitted from the feeding plate 23, at this time, the top tensioning roller 12 can be used to abut against the top surface of the film, and the tensioning degree of the film can be kept all the time by the tensioning roller 12. Due to the performance of the film itself, the elastic modulus of the film will fluctuate during transportation, and according to the situation of the produced film, the width and length of the film will change at any time, thus causing the tension of the film to change. At this time, in order to prevent the film from wrinkling or piling up, the servo motor 5 can be started to drive the rotating shaft 4 to rotate, and with the continuous rotation of the rotating shaft 4, the two bevel gears one 6 at both ends will also rotate. Since the two bevel gears one 6 and the two bevel gears two 9 are meshed with each other, the two bevel gears two 9 will also rotate at the same time as the two bevel gears one 6 rotate. At this time, the rotation of the two bevel gears two 9 will drive the two lead screws 8 to move continuously, so that the two moving blocks 10 will guide the tensioning roller 12 to move inside the fixing frame 1, so as to adjust the position of the tensioning roller 12 in real time according to the tension of the film. The change of the position of the tensioning roller 12 can effectively balance the tension change of the film material, prevent wrinkles from being generated, avoid product deformation and film tearing, greatly improve the processing precision, and in the use process, the tensioning assembly is easy to generate static electricity due to contact with the film, so that dust in the air is adhered. At this time, since the tensioning roller 12 is attached to the film above, the tensioning roller 12 will slightly rotate with the movement of the film, so that the outer wall of the tensioning roller 12 is in contact with the cleaning brush 15 in circulation, and the sliding plate 14 is always pressed downward by the elastic feature of the spring one 17, so that the sliding plate 14 pushes the cleaning brush 15 to be arranged above the tensioning roller 12, so that the cleaning brush 15 can always wipe and clean the outer wall of the tensioning roller 12, to clean the dust adhered to the tensioning roller 12, keep the tensioning roller 12 clean, improve the work efficiency, and avoid affecting the normal production.

[0045] Secondly, if the cleaning brush 15 needs to be replaced, the arc-shaped end of the two sliding blocks 22 can be manually squeezed into the inside of the recess 20 to separate the sliding blocks 22 from the top surface of the sliding plate 14, at this time the sliding plate 14 can be pulled up to slide on the guide rod 16, the clamping block 18 can be pulled out of the clamping groove 19, and the cleaning brush 15 can be replaced, after replacement, the clamping block 18 can be inserted into the clamping groove 19 again, the arc-shaped end of the sliding block 22 can be squeezed by the inner wall of the clamping groove 19 and pushed into the recess 20, when the clamping block 18 is completely inserted into the clamping groove 19, the sliding block 22 can be pushed out and attached to the top of the sliding plate 14 according to the rebound of the second spring 21, the cleaning brush 15 can be fixed on the guide rod 16 again through the ejection of the two sliding blocks 22 for next use.
