Description

Technical Field

[0001] This invention relates to tobacco machinery and equipment, and in particular to a double-roller compaction device for cigarette box labels. Background Technology

[0002] In the field of tobacco machinery technology, finished tobacco boxes after leaf re-drying need to be coded and labeled before leaving the production line for subsequent tracking, transportation, and tobacco processing formulas. This work is done by an automatic labeling device on the production line. These labeling devices mostly use non-contact labeling, using air pressure to blow the label paper onto the finished tobacco box. This method is prone to problems such as labels not adhering firmly to the tobacco box, unevenness, and corner defects. During subsequent warehousing, transportation, and stacking, these issues can lead to peeling, wrinkles, or even loss, seriously affecting the product's appearance quality and the quality tracking throughout its entire life cycle.

[0003] To ensure product quality, manual pressing with a brush is currently the only option, but the label application effect varies from person to person and results in significant manpower waste. Some manufacturers use an elastic pull ring that rolls across the cigarette box to press the label onto the box, but this method cannot move the pressing device up and down, cannot adapt to different labeling positions, cannot move the pressing roller back and forth, and cannot adjust the adhesion, resulting in less than ideal labeling results. This invention develops a double-roller pressing device for cigarette box labels, installed after the automatic labeling device on the production line. This device presses the label firmly and evenly onto the cigarette box, preventing labels from curling, wrinkling, or falling off during warehousing, transportation, and stacking. This ensures the product's appearance quality and the smooth operation of subsequent processes.

[0004] The current labeling method uses an elastic pull ring to tighten a rotating arm, which in turn causes the label attachment point, which is flat and fitted onto the cigarette box, to roll and press the label onto the cigarette box. This method cannot move the labeling structure up and down, cannot adapt to different labeling positions, cannot move the labeling roller back and forth, and cannot adjust the adhesion of the label, resulting in a less than ideal labeling effect. Summary of the Invention

[0005] The purpose of this invention is to provide a double-roller compaction device for cigarette box labels, which solves the problems of labels curling, wrinkling, or falling off and being lost during the process of cigarette box entry and exit, transportation and stacking, etc., so as to achieve labels intact and smooth, and provide assurance for the appearance quality of the product and the quality tracking of the entire product life cycle.

[0006] To achieve the above technical objectives, the present invention provides a double-roller compaction device for cigarette box labels, comprising: a base, a support, and a label-pressing roller located on the upper part of the support, further comprising: a connecting support and a label-pressing body; the label-pressing body has a cubic box structure and is provided with a dustproof cover plate, the bottom plate of the label-pressing body is installed and connected to the support via the connecting support, the label-pressing roller has two rollers arranged parallel to each other and spaced apart, the two label-pressing rollers are arranged on the outside of the label-pressing body; inside the label-pressing body is arranged: a movable shaft, the movable shaft has two sets arranged parallel to each other and spaced apart, the two sets of movable shafts are connected to the label-pressing rollers via a lever arm with an arc shape, and a spring is provided between the two sets of movable shafts and offset inward, so that the two label-pressing rollers are linked back and forth through the lever arm, the two sets of movable shafts and the spring.

[0033] In such Figures 1 to 2 In the preferred embodiment shown, the present invention provides a double-roller compaction device for cigarette box labels, mainly comprising a base 10, a bracket 20, a connecting bracket 30, and a label pressing body 40. The label pressing body 40 is surrounded by a dustproof cover, and its internal structure includes a base plate 2, four fixed shafts 3, two label pressing rollers 4, four movable shafts 5, four lever arms 6, one spring 7 and two auxiliary springs 11, two fork bars 8, and two hanging pins 9.

[0034] like Figure 1The base 10 is used to fix the label-pressing device to the ground. One end of the bracket 20 is fixed to the base 10 by welding, and the other end is connected to the connecting bracket 30 by screws through an opening. The connecting bracket 30 is at a 90-degree right angle, with one end connected to the bracket 20 and the other end connected to the label-pressing body 40. The bracket 20 has a waist hole, and the height of the label-pressing body 40 can be adjusted by adjusting the position of the connecting bracket 30 to adapt to different labeling heights.

[0035] like Figure 2 The connecting bracket 30 is connected to the base plate 2 of the label pressing body 40 by screws. Four fixed shafts 3 are located at the four corners of the base plate 2, used to fix the four dust covers to prevent dust from affecting the internal mechanical structure of the label pressing body 40. The two label pressing rollers 4 are connected vertically by left and right lever arms 6 and four movable shafts 5. There is a fork 8 between the two movable shafts 5, connected by a spring 7 in the middle. There is also an auxiliary spring 11, connected at one end to the movable shaft 5 and at the other end to a hanging pin 9. The two hanging pins 9 are fixed to the base plate 2 and the upper dust cover, respectively. Both the connecting bracket 30 and the base plate 2 have waist holes, allowing for adjustment of the overall position of the label pressing body 40, thereby adjusting the adhesion of the label and preventing damage to the label or box due to insufficient pressure or excessive pressure. The two rollers of the label pressing rollers 4 are made of rubber, which is elastic and maintains good compaction even on uneven surfaces.

[0036] The specific working process of the double-roller compaction device for cigarette box labels provided by this invention is as follows:

[0037] Under normal circumstances, the label roller 4 is in its initial state, i.e., the first roller is in front and the second roller is behind. When the cigarette box passes through:

[0038] 1. The front end of the cigarette box first touches the first roller of the pressure roller 4. The first roller moves to the right, and the left axis of the movable shaft 5 is pulled to the left by the lever arm 6.

[0039] 2. The movement of the left axis of the movable shaft 5 is driven by the middle spring 7 to move the right axis of the movable shaft 5 to the left.

[0040] 3. The movement of the right side of the movable shaft 5 drives the second roller of the label roller 4 to extend forward through the lever arm 6. The roller presses against the side of the cigarette box and rolls. Then the first roller of the label roller 4 also moves to the side of the cigarette box and rolls.

[0041] 4. When the two rollers of the label pressing roller 4 press parallel to each other on the side label of the cigarette box, the roller of the label pressing body 40 moves forward with the cigarette box. Under the rolling of the two rollers, the label is evenly attached to the box.

[0042] After the cigarette box passes through, the tension of the upper and lower auxiliary springs 11, through the movable shaft 5 and the lever arm 6, returns the two rollers of the label pressing roller 4 to their initial state. The two rollers of the label pressing roller 4 can press the label twice in succession, making the label adhere more firmly. Moreover, when the label pressing roller 4 presses the label, the spring is not working at its limit; the rollers will adaptively adjust the pressure on the label according to the spring tension, resulting in a better label pressing effect.

[0043] This invention develops a double-roller compaction device for cigarette box labels. Installed after the automatic labeling device on the production line, it presses the labels firmly and evenly onto the cigarette boxes, preventing labels from curling, wrinkling, or falling off during warehousing, transportation, and stacking. This ensures the product's appearance quality and provides quality tracking throughout its entire lifecycle. The double rollers compact the label twice, resulting in a stronger adhesion. Furthermore, the springs are not at their limit when pressing the label; the rollers adaptively adjust the pressure on the label based on the spring tension, resulting in better label compaction.

[0044] The connection of this invention has longitudinal and horizontal waist holes, which can be adjusted up and down and back and forth. At the same time, it has a double pressure roller design to protect the product by pressing it back and forth. The mechanical connection of the pressure roller, movable shaft, arm 6, spring and other workpieces forms a back and forth linkage, which can work continuously and reliably.

[0045] This invention provides a double-roller compaction device for cigarette box labels, which can compact the labels, ensuring they adhere firmly and flat, preventing labels from curling, wrinkling, or falling off during warehousing, transportation, and stacking. This invention uses two pressure rollers to compact the labels, resulting in a more secure adhesion. When the rollers press the label, the springs are not at their limit; the rollers adaptively adjust the pressure on the label according to the spring tension, resulting in better label compaction.

[0046] It should be understood that the scope of protection sought by this invention is not limited to the non-limiting embodiments, which are merely illustrative examples. The substantive scope of protection claimed in this application is further embodied in the scope provided by the independent claims and their dependent claims.
