Description

Technical Field

[0001] This invention relates to the field of cigarette equipment technology, and in particular to a pre-forming device for cigarette label paper. Background Technology

[0002] The FOCKE350 packaging machine's cigarette pack conveyor chain transports cigarette packs from the folding turret mold box into the cigarette pack channel. As the packs pass the large glue cylinder, glue is applied to the outer bevels and outer edges of the cigarette pack label paper on both sides, and the packs continue to be conveyed above the cigarette pack elevator. The elevator lifts the glued cigarette packs from the guide rails into the mold box of the cigarette pack conveying turret. At this point, the folding device completes the folding of the two outer bevels and two outer edges of the cigarette pack, and rejects any defective packs. The cigarette packs, folded by the pre-folding device, continue to be conveyed forward in the cigarette pack conveying channel via the second propulsion chain, entering the pre-forming device at the transfer turret. Finally, the elevator at the bottom of this pre-forming device lifts the cigarette packs and transfers them to the compression mold box of the turret, completing the final shaping of the cigarette packs.

[0003] The currently used medium-sized cigarette pack packaging machine is a modified FOCKE350 standard packaging machine adapted to produce medium-sized cigarette packs. Because the cigarette pack size has been reduced from large to small, the two outer bevels and two outer edges of the label paper are pre-folded by a pear-shaped pre-folding device before being conveyed by a lug chain to the existing pre-forming device for lifting. To prevent the pre-folded outer bevels and outer edges from springing open, the existing pre-forming device uses two flat guide plates. However, in actual operation, it has been found that the top of the label paper tends to curl upwards under tension, causing the pre-folded outer bevels and outer edges to detach from the flat guide plates. The two flat guide plates cannot effectively prevent the pre-folded outer bevels and outer edges from springing open, resulting in lower cigarette pack forming quality. Summary of the Invention

[0004] The purpose of this invention is to provide a pre-forming device for cigarette label paper to solve the problems mentioned in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A preforming device for cigarette label paper, comprising:

[0007] The left-side forming component includes a left-side support, a left-side guide bar, and a left-side crossbar. The left-side guide bar and the left-side crossbar are mounted on the left-side support, and the working surface of the left-side guide bar is perpendicular to the working surface of the left-side crossbar.

[0008] The right-side forming component includes a right-side support and a right-side guide block. The right-side guide block is mounted on the right-side support. The working surface of the right-side support is perpendicular to the working surface of the right-side guide block, and the working surface of the right-side support is parallel to the working surface of the left-side guide bar. The working surface of the right-side guide block is flush with the working surface of the left-side horizontal bar.

[0009] Optionally, the left guide bar is provided with a first connecting plate, the first connecting plate is perpendicular to the left guide bar, and the first connecting plate has a first connecting hole;

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figures 1 to 6 As shown, the present invention provides a pre-forming device for cigarette label paper, including a left forming component 100 and a right forming component 200. The left forming component 100 includes a left support 110, a left guide strip 120, and a left crossbar 130, which are mounted on the left support 110. The working surface of the left guide strip 120 is perpendicular to the working surface of the left crossbar 130. The right forming component 200 includes a right support 210 and a right guide block 220, which are mounted on the right support 210. The working surface of the right support 210 is perpendicular to the working surface of the right guide block 220 and parallel to the working surface of the left guide strip 120. The working surface of the right guide block 220 is flush with the working surface of the left crossbar 130.

[0035] The cigarette label paper preforming device provided by this invention, in use, involves installing the left support 110 in the left mounting hole of the existing FOCKE350 forming device, and the right support 210 in the right mounting hole of the existing FOCKE350 forming device. The cigarette pack is conveyed forward in the cigarette pack conveying channel and enters between the left forming component 100 and the right forming component 200. The left outer bevel and the left outer edge of the label paper are attached to the working surface of the left guide strip 120, and the right outer bevel and the right outer edge of the label paper are attached to the working surface of the left guide strip 120. The top of the label paper is attached to the working surface of the right support 210 and the working surface of the left horizontal bar 130 and the right guide block 220. The top of the label paper is limited by the left horizontal bar 130 and the right guide block 220 to prevent the top of the label paper from tilting upward under tension. This prevents the pre-folded outer corners and outer edges of the label paper from detaching from the cigarette label paper pre-forming device. The cigarette label paper pre-forming device can effectively keep the pre-folded outer corners and outer edges of the label paper from popping open, ensuring the quality of the cigarette pack forming.

[0036] In some embodiments, the left guide strip 120 is provided with a first connecting plate 121, which is perpendicular to the left guide strip 120. The first connecting plate 121 has a first connecting hole 122. The top of the left support 110 has a first screw hole 111, and a first screw passes through the first connecting hole 122 and is threaded into the first screw hole 111. This structure enables a detachable connection between the first connecting plate 121 and the left support 110, facilitating the assembly and disassembly of the left guide strip 120. For example, the first connecting hole 122 can be a strip-shaped hole extending towards the right forming component 200, allowing the left guide strip 120 to be adjusted in the direction of the right forming component 200, thereby adjusting the distance between the left guide strip 120 and the right support 210 to accommodate trademark paper of different widths. Of course, in other embodiments, the first screw hole 111 can also be located at the bottom of the left support 110.

[0037] In some specific embodiments, a limiting platform 112 is provided at the top of the left support 110, and the side wall of the first connecting plate 121 abuts against the side wall of the limiting platform 112. The limiting platform 112 limits the first connecting plate 121, preventing the first connecting plate 121 from deflecting relative to the left support 110 during use, thus ensuring the stability of the left guide bar 120. Of course, in other embodiments, the limiting platform 112 can also be provided at the bottom of the left support 110.

[0038] The front end of the left guide bar 120 is provided with an arc-shaped transition section 123 to ensure that the left outer bevel and the left outer edge of the label paper can move smoothly to the working surface of the left guide bar 120. Specifically, the end of the arc-shaped transition section 123 away from the left guide bar 120 gradually bends away from the right support 210.

[0039] In some embodiments, the left horizontal bar 130 is provided with a second connecting plate 131, which is parallel to the left horizontal bar 130 and has a second connecting hole 132. The top of the left support 110 has a second screw hole 113, and a second screw passes through the second connecting hole 132 and is threaded into the second screw hole 113. This structure enables a detachable connection between the second connecting plate 131 and the left support 110, facilitating the assembly and disassembly of the left horizontal bar 130.

[0040] In some specific embodiments, the left horizontal bar 130 is also provided with a through hole 134 that aligns with the first screw hole 111. The first screw passes through the through hole 134, and the first connecting hole 122 is threadedly connected to the first screw hole 111 to prevent the second connecting plate 131 from deflecting relative to the left support 110, thereby ensuring the stability of the left horizontal bar 130.

[0041] To ensure that the top of the label paper moves smoothly to the working surface of the left horizontal bar 130, in some embodiments, an arc-shaped transition strip 133 is provided at the front end of the left horizontal bar 130. Specifically, the end of the arc-shaped transition strip 133 away from the left horizontal bar 130 gradually curves upward.

[0042] In some embodiments, the right guide block 220 is provided with a third connecting plate 221, the third connecting plate 221 having a third connecting hole 222, and the right support 210 having a third screw hole. A third screw passes through the third connecting hole 222 and is threaded into the third screw hole. This structure enables a detachable connection between the third connecting plate 221 and the right support 210, facilitating the assembly and disassembly of the right guide block 220. Specifically, there are at least two third connecting holes 222, and the third screw hole is aligned with the third connecting holes 222 to prevent the third connecting plate 221 from deflecting relative to the right support 210 during use, thus ensuring the stability of the right guide block 220.

[0043] The pre-forming device for cigarette label paper provided by this invention is tailored to the compact structure of the FOCKE350. It utilizes the existing mounting holes of the FOCKE350 forming device, avoiding the need to drill holes again in the already narrow channel plate, and can effectively solve the quality defects of poor forming of cigarette label paper and exposed white at the bevel angle.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
