Description

[0002] After various existing commodities are produced, labels need to be attached to the commodities. Depending on the products, the requirements for the labels are also different. To meet the diverse needs of the market, some labels are no longer single-layer structures but multi-layer folding structures. To produce multi-layer folding labels, in order to process a wide-width label roll with printed patterns into individual labels, it is usually necessary to first slit the wide-width label roll, then fold it according to the slits, then cut it to a certain length, and finally, to prevent the folds between the multiple layers of the cut labels from opening, it is necessary to fix the multiple layers together; currently, although some processing links use automated equipment, effective connection between different equipment cannot be achieved. As a result, after the labels are processed on different equipment, it is necessary to manually transfer the semi-finished products processed by the previous equipment to the next equipment for processing, resulting in low automation and low production efficiency.

[0032] The present invention will be further described and explained below in conjunction with specific embodiments and the accompanying drawings of the specification:

[0033] Please refer to Figure 1, A multi-layer folding label processing device, comprising a feeding mechanism 10, a slitting mechanism 20, a folding mechanism 30, an edge-sealing mechanism 40, a cutting mechanism 50, a material collecting assembly 60, a pulling shaft 70, a traction roller 80 and an adjustment assembly 90. The pulling shaft 70 is located between the slitting mechanism 20 and the folding mechanism 30, and the traction roller 80 is located between the edge-sealing mechanism 40 and the cutting mechanism 50. Both the pulling shaft 70 and the traction roller 80 are driven by motors.

[0034] Please refer to Figure 1 , The feeding mechanism 10 includes a first bracket 11, a material-releasing disk 12, a third rotating shaft 13, a no-material sensor 14, a deviation rectifier 15 and a deviation induction sensor 16. The material-releasing disk 12 is located inside the first bracket 11, and the third rotating shaft 13, the no-material sensor 14, the deviation rectifier 15 and the deviation induction sensor 16 are located on one side of the first bracket 11. After the wide-width label roll is placed on the material-releasing disk 12, one end is smoothly extended, and then successively bypasses the third rotating shaft 13, the no-material sensor 14, the deviation rectifier 15 and the deviation induction sensor 16, and then extends to the slitting mechanism 20. The material-releasing disk 12 and the third rotating shaft 13 are arranged side by side. The no-material sensor 14, the deviation rectifier 15 and the deviation induction sensor 16 are located above the third rotating shaft 13. The third rotating shaft 13 guides the wide-width label material to be smoothly conveyed to the slitting mechanism 20. The deviation rectifier 15 cooperates with the deviation sensor 16 to correct the deviation of the running wide-width label material, preventing the wide-width label from running off and affecting the subsequent processes or causing failures. The no-material sensor 14 is used to stop the operation of the entire device through the system control when there is no material or the material is cut off in the wide-width label. Thus, it ensures the stable conveyance of the wide-width label to the slitting mechanism 20 without manual conveyance by the staff.

[0035] Please refer to Figure 1 and Figure 2, The slitting mechanism 20 is arranged side by side on the first support 11. The slitting mechanism 20 includes a slitting base 21, a slitting knife 22, a pneumatic throttle valve 23, and a pressure roller 24 installed above the slitting base 21. The pulling shaft 70 is installed on the slitting base 21. The pneumatic throttle valve 23 controls the clamping or loosening of the wide-width label material by the slitting knife 22 on the slitting base 21. The slitting knife 22 is disc-shaped, and its outer periphery is serrated at equal intervals. One end of the wide-width label material passes through the feeding mechanism 10 and then lies flat on the slitting base 21, passing successively between the pressure roller 24 and the slitting base 21, between the slitting knife 22 and the slitting base 21, and between the pulling shaft 70 and the slitting base 21, and lies flat on the slitting base 21. The pressure roller 24 presses the wide-width label flat. When the pulling shaft 70 rotates, it drives the wide-width label material to move, and the pressure roller 24 assists the wide-width label material to move smoothly on the slitting base 21. By adjusting the gap between the slitting knife 22 and the slitting base 21 through the pneumatic throttle valve 23, it is ensured that when the wide-width label material moves, it drives the slitting knife 22 to rotate. After the serrated slitting knife 22 cuts the wide-width label material into several strips, a dotted folding line is formed between different slittings. Since the different strips are not completely separated, it is convenient for the wide-width label material to be folded along the slitting line. The number of slitting knives 22 can be increased or decreased according to the number of slittings required, and the distance between each slitting knife 22 can be adjusted as needed, generally set at equal intervals. Thus, the automatic slitting of the wide-width label is completed without manual slitting and conveying by workers.

[0036] Please refer to Figure 1 and Figure 3 , The folding mechanism 30 includes a second support 31 and a folding assembly 32. The adjustment assembly 90 includes two guide rails 91, a winding shaft 92, a balance assembly 93, and a sensor combination 94. The two guide rails 91 are arranged side by side and vertically installed inside the second support 31. The two ends of the winding shaft 92 are respectively fixed directly above the two guide rails 91. The balance assembly 93 includes two sliders 931, a first rotating shaft 932, and a second rotating shaft 933. The two sliders 931 are respectively slidably connected to the two guide rails 91. The two ends of the first rotating shaft 932 are respectively fixed on the two sliders 931. The two ends of the second rotating shaft 933 are respectively fixed on the two sliders 931. The first rotating shaft 932 and the second rotating shaft 933 are respectively located on both sides of the two guide rails 91. The sensor combination 94 includes an upper sensor 941 and a lower sensor 942. The upper sensor 941 and the lower sensor 942 are respectively installed on the upper and lower sides of the second support 31 and correspond to the guide rails 91.

[0037] Please refer to Figure 1 , Figure 3 and Figure 4, the folding assembly 32 includes a folder combination 321 and a shaping hub 322. The shaping hub 322 is located above the folder combination 321 and is rotatably connected to the second bracket 31. The folder combination 321 includes two clamping plates 3211 and a plurality of partition plates 3212 located between the two clamping plates 3211. The folder combination 321 is arranged side by side with the guide rail 741. The distances between the two clamping plates 3211 and the two guide rails 91 are equal respectively. The width between the two clamping plates 3211 is less than the length of the second rotating shaft 933. The number of partition plates 3212 is the same as the number of slitting knives 22. The thickness of the partition plates 3212 gradually decreases from the side far away from the guide rail 91 to the side close to the guide rail 91. Chamfers are provided at the bottoms of the opposite sides of the two partition plates 3212. The space between the two partition plates 3212 is in the shape of a funnel with a wider bottom and a narrower top.

[0038] One end of the wide-width label material bypasses the material pulling shaft 70, then successively bypasses the lower side of the first rotating shaft 932 from below the first rotating shaft 932, bypasses the upper side of the winding shaft 92 from above the winding shaft 92, bypasses the lower side of the second rotating shaft 933 from below the second rotating shaft 933, passes through between the two clamping plates 3211, then bypasses the shaping hub 322 from above the shaping hub 322, and then successively passes through the edge sealing mechanism 40, the traction roller 80 and the cutting mechanism 50. When the wide-width label material passes through between the two clamping plates 3211, the wide-width label is folded along the folding line. At the same time, when the folded label bypasses the shaping hub 322, the label is twisted into a lying state and continues to move. The arc of the shaping hub 322 can be increased to ensure that the folded label remains in the folded state during the movement. Thus, the wide-width label is automatically transported to the folding combination 321 and automatically folded without manual folding by the staff.

[0039] During the movement of the wide-width label, when the speed at which the traction roller 80 drives the wide-width label to move is faster than the speed at which the material pulling shaft 70 drives the wide-width label to move, the length of the wide-width label between the material pulling shaft 70 and the traction roller 80 gradually becomes shorter. The wide-width label pulls the first rotating shaft 932 and the second rotating shaft 933 to move upward along the guide rail 91 through the slider 931. When the balance assembly 93 moves upward to the position where it is sensed by the upper sensor 941, the traction roller 80 stops running. As the material pulling shaft 70 rotates continuously, the length of the wide-width label between the material pulling shaft 70 and the traction roller 80 gradually becomes longer. Under the action of its own gravity, the first rotating shaft 932 and the second rotating shaft 933 move downward along the guide rail 91 through the slider 931. When the balance assembly 93 moves downward to the position where it is sensed by the lower sensor 942, the traction roller 80 starts to run and the material pulling shaft 70 stops rotating. As the length of the wide-width label between the material pulling shaft 70 and the traction roller 80 gradually becomes shorter again, the balance assembly 93 moves upward along the guide rail 91 again. Thus, under the adjustment of the adjustment assembly 90, the coordinated operation of the material pulling shaft 70 and the traction roller 80 is realized, ensuring the smooth movement of the wide-width label.

[0040] Please refer to Figure 1 and Figure 5 As shown in Figure 5 , the edge sealing mechanism 40 includes a third bracket 41 and an edge sealing assembly 42 mounted on the third bracket 41. The third bracket 41 is connected to the second bracket 31. The edge sealing assembly 42 includes an edge sealing base 421, an adjusting handwheel 422, an ultrasonic vibrator 423, and an edge sealing knife 424. The ultrasonic vibrator 423 is fixed on the edge sealing base 421, and the edge sealing knife 424 is located above the ultrasonic vibrator 423. One end of the folded label bypasses the shaping hub 322 and then passes between the edge sealing knife 424 and the ultrasonic vibrator 423. Driven by the motor, the edge sealing knife 424 moves towards the ultrasonic vibrator 423 until it presses down and touches the surface of the folded label and the ultrasonic vibrator 423, and uses ultrasonic vibration to fuse and seal the multi-layer folded label to form a sealed fixed-length label, completing the automatic edge sealing of the label without manual edge sealing by the staff. By adjusting the handwheel 422, the horizontal distance between the edge sealing base 421 and the cutting mechanism 50 is adjusted to ensure that the edge sealing position of the folded label corresponds to the cutting position.

[0041] Please refer to Figure 1 and Figure 6 As shown in Figure 6 , the cutting mechanism 50 includes a fourth bracket 51 and a cutting assembly 52. The cutting assembly 52 includes a cutting knife 521 and a cutting knife base 522. The cutting knife base 522 is fixed on the fourth bracket 51, and the cutting knife 521 is located above the cutting knife base 522. The traction roller 80 is mounted on the cutting knife base 522. After passing through the edge sealing assembly 42, the folded label passes between the traction roller 80 and the cutting knife base 522, and between the cutting knife 521 and the cutting knife base 522 in sequence. When the motor drives the traction roller 80 to rotate, it pulls the folded label to move smoothly on the cutting knife base 522. Driven by the motor, the cutting knife 521 moves downward. When it touches the surface of the folded label and the cutting knife base 522, it cuts the folded label at the set break point of the folded label; Driven by the motor, the cutting knife 521 moves upward. When the folded label moves past the set length, the cutting knife 521 moves downward again to cut the folded label. By setting the interval time of the up and down movement of the cutting knife 521 and the moving speed of the folded label on the cutting knife base 522, a fixed-length single folded label can be cut out. Thus, the traction roller 80 automatically conveys the folded label to the cutting assembly 52 and automatically cuts out a single folded label without manual operation.

[0042] Please refer to Figure 1 and Figure 7 As shown in Figure 7 , the material receiving assembly 60 includes a pusher 61 and a material receiving groove 62. The pusher 61 is located between the cutting knife base 522 and the material receiving groove 62. After the cutting knife 521 cuts out a fixed-length single folded label, the motor drives the pusher 61 to push the single folded label into the material receiving groove 62, thus realizing the automatic collection of a single folded label without manual collection by the staff.

[0043] In summary, through the pulling of the material pulling shaft 70 and the traction roller 80, and the adjustment of the adjustment assembly 90, the smooth movement of the wide-width label on the loading mechanism 10, the slitting mechanism 20, the folding mechanism 30, the edge sealing mechanism 40, and the cutting mechanism 50 is realized. The loading mechanism 10 continuously and stably supplies a flat wide-width label to the slitting mechanism 20. The slitting mechanism 20 slits the wide-width label and forms a folding line. The folding mechanism 30 folds the wide-width label along the folding line. The edge sealing mechanism 40 fuses the folded label at a fixed length to prevent the folded label from naturally unfolding. The cutting mechanism 50 cuts the edge-sealed folded label at a fixed length at a set position. The material receiving assembly 60 collects the cut single folded labels. The above transmission process from the wide-width label raw material to the formation of a single folded label is fully automated without manual operation by workers, improving the automation degree of the production of multi-layer folded labels and the production efficiency.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
