Description

Technical Field

[0001] The utility model relates to the technical field of cigarette rod packaging, in particular to a packaging film adjusting device of a cigarette rod packaging machine. Background Art

[0002] In the process of cigarette distribution, the cigarette cartons required by each merchant need to be packaged to facilitate fast delivery by drivers. In order to improve packaging efficiency, film wrapping machines are usually used for automatic packaging.

[0003] After searching, the publication number is CN214356987U, a tobacco packaging equipment with integrated label and thinness. The scheme discloses a support frame, a mixed stacking output rack, a packaging film, a transfer rack, an output mechanism, an input belt, a first-class standard cigarette assembly rack, a primary speed difference belt, a second-class standard cigarette assembly rack, a secondary speed difference belt, and a pushing mechanism. The input belt is installed on the upper end of the support frame, and the mixed stacking output rack is arranged on one side of the first-class standard cigarette assembly rack. The tobacco packaging equipment pushes the cigarette rods on the second-class standard cigarette assembly racks on both sides through the opening into the lower end of the first-class standard cigarette assembly rack through the pushing mechanism, so that the cigarette rods on the two assembly racks are stacked with labels and thinness and output through the output mechanism, thereby completing the stacked tobacco packaging with integrated label and thinness. Figure 1 As shown, in the process of pushing the cigarette rod 10 to the packaging machine 9 by the pushing member 11, the cigarette rod 10 completes the wrapping action by pressing the packaging film 3. However, since the upper end of the packaging film is in a taut state, force will be applied when the packaging film is pulled to make the cigarette rod 10 move backward, thereby affecting the relative position of the cigarette rod 10 in the packaging film 3, so that after the cigarette rod is packaged, the quality does not meet the process requirements, resulting in poor packaging quality, and rework and repackaging are required, which further affects the packaging efficiency and is also prone to cause equipment failure.

[0018] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0019] See also Figure 1-3 As shown, a packaging film adjusting device of a cigarette strip packaging machine of the present invention comprises a mounting frame 1 for placing a packaging film 3, a plurality of guide rollers 2 for tensioning the packaging film 3 are rotatably provided on the mounting frame 1, the packaging film 3 passes through the plurality of guide rollers 2 in an S shape in sequence, a support frame 4 is provided between the mounting frame 1 and a film packaging machine 9, sliders 6 are provided on both sides of the support frame 4 and are slidably connected thereto, a supporting roller 7 is rotatably provided between the two sliders 6, a driving device for driving the slider 6 to move up and down is provided above the slider 6, the packaging film 3 passes through the guide rollers 2 in sequence after passing through the support rollers 7 from above, and is perpendicular to one side of a conveyor belt 8, and the packaging film 3 passes through the guide rollers 2 in sequence, The packaging film 3 plays a tensioning role to prevent the packaging film 3 from being too loose when pulled and affecting the packaging quality. When the pushing member 11 pushes the tobacco rod to the film wrapping machine 9, the cylinder 5 also works at the same time, driving the slider 6 to move downward, thereby driving the supporting roller 7 to move downward as well, so that the packaging film 3 passing over it becomes loose, so that the tobacco rod 10 is no longer affected by the tensioning force of the packaging film 3 during the pushing process, thereby ensuring that the tobacco rod 10 and the packaging film 3 are in a preset position, thereby ensuring that after passing through the film wrapping machine, a product that meets the process requirements can be packaged, effectively improving the packaging quality.

[0020] Specifically, the driving device includes a cylinder 5 , the upper end of the cylinder 5 is mounted on the support frame 4 , the output end of the cylinder 5 is connected to a slider 6 , and the slider 6 is driven to move up and down with the support roller 7 , so as to tension and relax the packaging film 3 .

[0021] Preferably, a telescopic rod 12 is provided between the cylinder 5 and the slider 6, and a locking screw is provided on the telescopic rod 12. One end of the telescopic rod 12 is connected to the output end of the cylinder 5, and the other end of the telescopic rod 12 is connected to the slider 6. Since the stroke of the cylinder 5 is fixed, the required length of the packaging film for packaging tobacco rods 10 of different specifications is inconsistent. By setting the telescopic rod 12 and adjusting the extension distance of the telescopic rod 12, the descending height of the slider 6 can be adjusted, thereby adjusting the relaxation length of the packaging film 3, thereby meeting the production requirements of tobacco rods 10 of different specifications, thereby increasing the practicality of the device.

[0022] Furthermore, a scale 13 for adjusting the lowering height of the support roller 7 is provided on the sliding end of the telescopic rod 12, which is used to refer to the extension distance of the telescopic rod 12 for adjustment so that the extension distances on both sides are consistent, thereby keeping the heights of both sides of the support roller 7 consistent, so that the packaging film 3 is in a horizontal state on the support roller 7, thereby ensuring the packaging quality.

[0023] Furthermore, a T-shaped slide groove 14 is provided on the side plate of the support frame 4, and a T-shaped block is provided behind the slider 6. The T-shaped block is slidably installed on the T-shaped slide groove 14. The T-shaped slide groove 14 plays a guiding role, so that the slider 6 runs more smoothly.

[0024] Furthermore, there are three guide rollers 2, which are arranged parallel to each other on the mounting frame 1. The three guide rollers 2 guide the packaging film 3 in an interlaced manner, so that the packaging film 3 is stably output in a taut state, thereby ensuring the smooth operation of the entire device.

[0025] When in use, the packaging film adjusting device of a cigarette strip packing machine of the present embodiment passes the packaging film 3 through the guide roller 2 in sequence, which plays a role of tensioning the packaging film 3, preventing the packaging film 3 from being too loose when pulled, thereby affecting the packaging quality. When the pusher 11 pushes the cigarette strip to the film wrapping machine 9, the cylinder 5 also works at the same time, driving the slider 6 to move downward, thereby driving the support roller 7 to follow the downward movement, so that the packaging film 3 passing over it becomes loose, so that the cigarette strip 10 is no longer affected by the tensioning force of the packaging film 3 during the pushing process, thereby ensuring that the cigarette strip 10 and the packaging film 3 are in a preset position, thereby ensuring that after passing through the film wrapping machine, a product that meets the process requirements can be packaged, effectively improving the packaging quality. The packaging film adjusting device of a cigarette strip packing machine of the present utility model effectively improves the packaging quality, reduces the failure rate, and has the characteristics of a wide range of applications and strong practicality.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
