Description

Technical Field

[0001] This invention relates to tobacco packaging equipment, specifically to a label paper inner tongue folding mechanism for a YB45 type hard box packaging machine. Background Technology

[0002] In the YB45 hard-pack packaging machine, when the small cigarette pack reaches the position directly above wheel number five for folding, the inner flap of the label should normally be folded inside the lid, so that the front of the lid should be the thickness of two layers of label paper. In actual production, the inner flap of the label paper often opens up, and the opened flap is just pressed down by pattern 12 on the front of the small box, inserting into the interior position of pattern 12 on the front of the small box. Figure 1 The inner tab of the label paper inserted inside is stuck to the adhesive dots on the front, preventing the small box lid from opening properly; this is known as a small box lid insertion defect. This defect is classified as a Class A quality defect by the process quality department, seriously affecting product quality. Currently, most locomotives use an arc-shaped plate at the fifth position of the fifth wheel to prevent this. However, current technical improvements, such as adding an arc-shaped plate above the fifth wheel, result in non-standard workpieces that, after long-term wear, can scratch the label paper on the small box and also easily cause large diagonal seams on the sides of the small box, a quality defect. Summary of the Invention

[0003] This invention proposes a label paper inner tongue folding mechanism for the YB45 hard box packaging machine. This structure can realize the pre-bending of the label paper. After the pre-bending, the label paper is folded by the folder, which solves the problem of quality defects in the small box lid of the YB45 packaging machine and ensures the product quality of small box packaging.

[0004] Specifically, a label paper inner tongue folding mechanism for a YB45 type hard box packaging machine is proposed, including a label paper inner tongue pre-bending station and a folding station, with the pre-bending process located before the folding station; the label paper inner tongue pre-bending station includes a label paper transverse conveying guide and a bracket, the label paper transverse conveying guide and the bracket being arranged opposite to each other, the bracket including a first bracket and a second bracket arranged perpendicularly to each other, the first bracket including a vertically arranged elongated hole for installing a pressure roller; the second bracket is provided with a bending groove, the width of which is set to half the length of the label paper inner tongue; the pressure roller includes a rubber roller wheel, with a ball bearing embedded in the middle of the rubber roller wheel. The pressure roller is installed in the elongated hole; the folding station includes a label paper inner tongue folder, which includes a positioning push plate, a folding plate, and a bracket. The bracket has a hollowed-out part with screws inside. The positioning push plate and the folding plate have through holes through which the screws pass. The positioning push plate and the folding plate are fixed to the bracket by the cooperation of nuts and screws. The folding plate is positioned above the positioning push plate. The positioning push plate is designed to be adjustable. The positioning push plate includes a fixing part and a positioning part. The fixing part and the positioning part are connected by a pin hinge structure, which allows the positioning part to rotate around the pin shaft. The fixing part and the positioning part can be fixed at a certain angle by the pin hinge structure.

[0005] As a preferred technical solution, the folding plate is configured in a "T" shape, with the head of the "T" shape passing through the inner tongue of the trademark paper between it and the positioning component.

[0006] As a preferred technical solution, the positioning component is provided with spaced protrusions to hold the inner tongue of the label paper in place, making it easy to fold.

[0007] As a preferred technical solution, the positioning push plate also includes a fastening structure. After the position of the positioning component is adjusted by the adjustable structure, the positioning component can be fixed by the fastening structure.

[0008] As a preferred technical solution, the fastening structure is a fastening screw, and the process of tightening the fastening screw further fixes the positioning component.

[0009] As a preferred technical solution, the head side of the positioning component is provided with a through hole, through which the fastening screw can pass. When the fastening screw is tightened, it abuts against the pin wall that penetrates the head of the positioning component, thereby further fixing the angle of the positioning component.

[0010] As a preferred technical solution, one end of the second bracket is provided with a slope, and the inner tongue of the trademark paper enters the bracket along the slope.

[0011] As a preferred technical solution, the transverse conveying guide bar of the trademark paper is equipped with a positioning roller, which is arranged in parallel and staggered with the pressure roller, and the positioning roller is located on the outside of the pressure roller.

[0012] As a preferred technical solution, the positioning roller is located on the edge of the bending groove of the first bracket, the pressure roller is pressed into the bending groove for pre-bending the inner tongue of the trademark paper, and the positioning roller is used to fix and position the inner tongue of the trademark paper.

[0013] As a preferred technical solution, the width of the pressure roller is 3-4 cm smaller than the width of the bending groove.

[0014] This invention achieves the following technical advantages over existing technologies: This patent discloses a label paper inner tongue folding mechanism for a YB45 type hard box packaging machine, comprising a pre-bending station and a folding station. At the pre-bending station, the label paper inner tongue can be bent to different angles by adjusting the height of the pressure roller. Furthermore, at the folding station, the positioning push plate structure of the label paper inner tongue folder is adjusted, and the positioning element of the positioning push plate is adjusted to an adjustable angle structure. After the angle is adjusted, it is fixed to adapt to the bending angle of the label paper inner tongue.

[0015] Therefore, by pre-bending the inner flap of the label paper, the curved plate in the existing process is no longer needed when folding above the No. 5 wheel, preventing the small box from being inserted into the lid. This ensures the squareness of the small box packaging and avoids quality defects such as large diagonal seams on the sides. The design of the micro-bending process for the inner flap of the label paper solves the problem of small box lid insertion defects in the YB45 packaging machine, ensuring the product quality of small box packaging and reducing market feedback on small cigarette packs. The micro-bending process for the inner flap of the label paper is an industry first, pioneering experience in process improvement and providing a reference for future process refinement.

"Multiple" should be understood as two or more.

[0032] Example

[0033] Currently, in the YB45 hard-pack packaging machine, defects in the small box lid are all caused by an excessively large opening angle of the inner tongue at the fifth station directly above the fifth wheel, when the inner tongue contacts the aluminum foil cigarette pack. The opening angle of the inner tongue is related to factors such as the material of the label paper, the pressure of the inner tongue metal pressure roller 23, and the machine's running speed. Among these, only the pressure of the inner tongue metal pressure roller 23 is adjustable, and adjusting its pressure cannot completely eliminate the quality defects in the small box lid. Therefore, designing a device for slight bending of the inner tongue can effectively overcome various adverse factors leading to an excessively large opening angle, causing the inner tongue to bend slightly inward when folding at the fifth station of the fifth wheel, thus avoiding the occurrence of quality defects in the small box lid. Based on the above considerations, the packaging machine is improved without adding any equipment or components. Since the inner tongue is in an unfolded state on the label paper before it folds in the transverse channel, designing and modifying a slight bending device at this location is most suitable.

[0034] Specifically, based on the above technical analysis, the technical solution of this invention improves the glue coating device for the inner tongue 11 of the trademark paper by disassembling the glue coating claw and the corresponding glue coating roller in the existing glue coating device, making it easier to design and install a new roller. This is achieved by modifying the glue coating roller bracket, such as... Figure 2 As shown, the bracket includes a first bracket 21 and a second bracket 22 arranged perpendicularly to each other. The first bracket 21 includes a hole for mounting the roller. Currently, the hole is a round hole, which is improved by being a vertically arranged elongated hole 211. The round hole is replaced with a vertically arranged elongated hole 211, through which the pressure roller 23 for bending the inner tongue 11 of the label paper can be installed and fixed. In the YB45 type hard box packaging machine, the size of the elongated hole 211 can be set to an elongated elliptical hole with a width of about 6mm and a length of 8mm to 14mm. The pressure roller 23 is installed in the elongated hole 211, and the height of the pressure roller 23 can be adjusted through the elongated hole 211.

[0035] Furthermore, such as Figure 3 As shown, the pressure roller 23 is configured as a rubber roller (material can be PU polyurethane) including an outer ring, with a ball bearing embedded in the center of the rubber roller. The center of the ball bearing passes through the roller shaft, and the pin 313 is fixed in the elongated hole 211. In the YB45 type hard box packaging machine, the width of the rubber roller is set to 7mm, and the diameter of the entire pressure roller 23 is set to 32mm. By adjusting the roller shaft of the pressure roller 23 up and down, the thickness of a label paper is maintained between the rubber roller and the bracket. When the inner tongue 11 of the label paper is conveyed laterally, it can pass smoothly through the gap between the rubber roller and the bracket, and also play a role in stabilizing the label paper when the inner tongue bends.

[0036] Further reference Figure 2 The second bracket 22 is provided with a bending groove 221, the width of which is set to half the length of the inner tongue 11 of the label paper. This arrangement ensures that the bending position of the inner tongue 11 is precisely at the middle of the inner tongue. Furthermore, one end of the second bracket 22 is sloped. During operation, the inner tongue 11 of the label paper enters the bracket along the slope, facilitating the lateral transport of the label paper. Further, as... Figure 2-5As shown, the transverse conveyor guide 24 for label paper has a hole (not shown) for mounting a positioning roller 242. The positioning roller 242 is arranged parallel to and staggered with the pressure roller 23, and the positioning roller 242 is located outside the pressure roller 23. Furthermore, the positioning roller 242 is positioned along the edge of the bending groove 221 of the first bracket 21. When the pressure roller 23 is pressed into the bending groove 221 for pre-bending the inner tongue 11 of the label paper, the positioning roller 242 positions the inner tongue 11 of the label paper, working together with the pressure roller 23 to bend the inner tongue 11 of the label paper. Furthermore, the width of the roller of the pressure roller 23 is designed to be 3-4 cm smaller than the width of the bending groove 221 to facilitate bending operations. The transverse conveyor guide 24 for label paper is also arranged opposite to the bracket. Furthermore, the first bracket 21 also includes a first hole 212, and correspondingly, the transverse conveyor guide 24 for label paper has a second hole 241 for mounting screws 34 to connect and fix it to the transverse conveyor guide 24. The positioning roller 242, pressure roller 23, and second bracket 22 are located in the space between the transverse conveying guide 24 of the label paper and the support 33 of the first bracket 21. The inner tongue 11 of the label paper passes under the transverse conveying guide 24 of the label paper and is pre-bent by the action of the positioning roller 242 and pressure roller 23. The above design forms the pre-bending station of the label paper inner tongue 11 folding mechanism of the present invention. By adjusting the height of the pressure roller 23, the inner tongue 11 of the label paper can be bent to different angles in the pre-bending station designed above. Moreover, the synergistic effect between the components in the pre-bending station design makes the pre-bending station stable and prevents the angular deviation of the inner tongue 11 of the label paper from occurring during bending.

[0037] After the inner tongue 11 of the trademark paper emerges from the pre-bending station, it enters the folding station, where the pre-bent inner tongue 11 of the trademark paper is folded. For example... Figure 6-7 As shown, the folding station includes a label paper inner tongue 11 folder. Specifically, the folder includes a positioning push plate, a folding plate 32, and a bracket 33. The bracket 33 has a cutout 331, in which a screw 34 is installed. Correspondingly, the positioning push plate and the folding plate 32 have through holes through which the screw 34 passes. The positioning push plate and the folding plate 32 are fixed to the bracket 33 by the cooperation of the nut 35 and the screw 34. The positioning push plate is designed to be adjustable and includes a fixing member 311 and a positioning member 312. After the fixing member 311 is fixed to the cutout 331, the fixing member 311 and the positioning member 312 are connected by a pin hinge structure, allowing the positioning member 312 to rotate around the pin shaft 313. The fixing member 311 and the positioning member 312 can be set at a certain angle after being fixed by the pin hinge structure. Those skilled in the art will recognize that the pin hinge structure includes a pin 313 with a threaded end. After the pin 313 passes through the through hole, the end is tightened with a screw. The gradual tightening process fixes the positioning member 312 at a certain angle.

[0038] The folding plate 32 is arranged in a "T" shape, with the head of the "T" shape passing through the inner tongue 11 of the trademark paper between it and the positioning member 312. Furthermore, the folding plate 32 is located above the positioning push plate, with the head of the folding plate 32 and the positioning member 312 at a certain angle. The pre-bent inner tongue 11 of the trademark paper abuts against the positioning member 312 and the folding plate 32, and is folded.

[0039] Preferably, the positioning member 312 has a spaced-apart protrusion structure (not shown in the figure) on the side facing the inner tongue 11 of the trademark paper. The protrusion structure can be used to hold the inner tongue 11 of the trademark paper in place, making it easy to fold. The protrusion structure can be set as a row of protrusions, or it can be set as multiple protrusions arranged in a row.

[0040] Preferably, the positioning push plate may further include a fastening structure. After the position of the positioning element 312 is adjusted by the adjustable structure, the positioning element 312 can be fixed by the fastening structure. The fastening structure can be a fastening screw 314. Those skilled in the art will understand that the tightening process of the fastening screw 314 can fix the positioning element 312 for the first time. However, in actual production, to prevent loosening during the production process, a through hole can be provided on the side of the head of the positioning element 312. The fastening screw 314 is inserted through the through hole, and then the fastening screw 314 passes through the head of the positioning element 312. During the tightening process, it abuts against the wall of the through pin 313, thereby further fixing the angle of the positioning element 312.

[0041] In actual operation, after the pre-bent inner tongue 11 of the trademark paper enters the folding station, it enters between the positioning plate and the folding plate 32 of the folder according to the preset path. The folder extends forward as a whole and presses down to fold the pre-bent inner tongue 11 of the trademark paper.

[0042] The above folding mechanism is suitable for the YB45 hard box packaging machine. When the inner tongue 11 of the label paper folds above the No. 5 roller, the curved plate in the existing production line is not required, and it can also prevent the small box lid from being inserted. It can ensure the squareness of the small box packaging and avoid quality defects such as large diagonal seams on the sides.

[0043] The design of a micro-bending process for the inner tongue 11 of the label paper solved the quality defect problem of the small box lid insertion in the YB45 packaging machine, ensuring the product quality of small box packaging and reducing market feedback on small cigarette packs. This micro-bending process for the inner tongue 11 of the label paper is an industry first, pioneering experience in process improvement and providing a reference for future process refinement.

[0044] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
