Description

Technical Field

[0001] This invention relates to the field of label die-cutting technology, and in particular to a die-cutting device. Background Technology

[0002] Label tape is the base tape for making labels, consisting of a backing paper tape and a face paper tape adhered to the backing paper tape. The face paper tape has an adhesive layer, which bonds the face paper tape and the backing paper tape together. The face paper tape is composed of waste tape and multiple spaced labels. In the technological development of die-cutting of this type of label tape, early methods primarily used separate die-cutting. The specific process of separate die-cutting is as follows: first, the label tape is separated into a face paper tape and a backing paper tape; then, a die-cutting mechanism cuts the face paper tape to form waste tape and multiple labels; after the waste tape is wound up, the labels are pressed and adhered to the backing paper tape; finally, the backing paper tape and labels are wound up. This die-cutting method arose because early die-cutting mechanisms had limited precision and could not accurately die-cut the face paper tape without separating the label tape; therefore, a separation step was necessary to ensure the die-cutting effect. Its application range is wide, especially suitable for products with complex shapes, high cutting precision requirements, and strict positioning requirements for the label and backing paper tape. However, the separate die-cutting process is cumbersome. With the advancement of laser die-cutting technology, laser mechanisms have begun to be applied to label tape die-cutting, thus giving rise to non-separate die-cutting. In this die-cutting method, the label tape remains in a state where the face paper tape and backing paper tape are not separated. The laser mechanism directly cuts the face paper tape to form waste tape and multiple labels. After the waste tape is wound up, the backing paper tape containing the labels is wound up directly. The core of this transformation is that the laser die-cutting mechanism can precisely control the cutting depth, cutting only the face paper tape without damaging the backing paper tape, eliminating the need for label tape separation. Non-separate die-cutting is more suitable for simple shapes and can meet the needs of standardized label products for high-speed, large-scale continuous production. However, non-separate die-cutting is not suitable for products with high requirements for the positioning of the label and backing paper tape.

[0003] Current die-cutting equipment has limited functionality, only capable of performing either separate or non-separate die-cutting. To meet different die-cutting processing needs, some companies often need to equip themselves with both types of die-cutting equipment, which not only significantly increases equipment procurement costs but also increases the floor space required for their workshops. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a die-cutting equipment that can simultaneously meet different die-cutting processing needs, which helps to reduce equipment procurement costs and workshop floor space for enterprises.

[0005] According to an embodiment of the present invention, a dual-process laser die-cutting equipment includes a frame, on which are arranged: a separation mechanism; a conveyor belt; a laser die-cutting mechanism for laser-cutting labels and waste strips from the face paper strip in the label material strip or the face paper strip on the conveyor belt, the conveyor belt being able to support and transport the cut labels; a peeling mechanism being able to peel the waste strip from the back paper strip or the conveyor belt; and a pressing mechanism; the label material strip can first pass through the separation mechanism, the separation mechanism separating the face paper strip and the back paper strip in the label material strip from each other, the conveyor belt supporting the face paper strip and pressing it against the back paper strip. In a synchronous motion, the laser die-cutting mechanism laser-cuts labels and waste strips from the face paper tape on the conveyor belt. The conveyor belt supports and transports the cut labels. The peeling mechanism peels the waste strip from the conveyor belt, and the pressing mechanism presses and adheres the labels on the conveyor belt to the back paper tape, thus completing the separate die-cutting of the label tape. Alternatively, the label tape can pass directly through the laser die-cutting mechanism, which laser-cuts labels and waste strips from the face paper tape in the label tape. The peeling mechanism peels the waste strip from the back paper tape, thus completing the non-separate die-cutting of the label tape.

[0006] It has at least the following beneficial effects:

[0007] This dual-process laser die-cutting equipment, through its rational structural design, can achieve both separate and non-separate die-cutting of label strips. When separate die-cutting is required, the label strip can be processed according to the corresponding feeding sequence and processing steps; when non-separate die-cutting is needed, it can also be operated through the corresponding process. This eliminates the need for companies to purchase two separate machines; a single dual-process laser die-cutting machine can meet different die-cutting processing needs, not only reducing equipment procurement costs but also saving workshop floor space.

[0008] The dual-process laser die-cutting equipment according to an embodiment of the present invention further includes an unwinding mechanism and a winding mechanism, wherein the unwinding mechanism is used to unwind the label material tape and the winding mechanism is used to wind up the backing paper tape with the label attached.

[0009] According to an embodiment of the present invention, a dual-process laser die-cutting equipment further includes two sixth rollers, which are arranged vertically on the frame and positioned between the unwinding mechanism and the conveyor belt. In the case of separate die-cutting of label tape, the separating mechanism consists of the two sixth rollers. The label tape released by the unwinding mechanism first enters the gap between the two sixth rollers, and the two sixth rollers respectively guide the face paper tape and the back paper tape in the label tape to separate from each other. In the case of non-separate die-cutting of label tape, a guide channel is formed between the two sixth rollers. The label tape released by the unwinding mechanism first passes through the guide channel and then through the laser die-cutting mechanism.

[0010] The dual-process laser die-cutting equipment according to an embodiment of the present invention further includes a fifth roller, which is disposed on the frame and located above the rear end of the conveyor belt. In the case of separate die-cutting of label tape, the pressing mechanism is the fifth roller. The bottom paper tape is first wound around the fifth roller, and the fifth roller guides the bottom paper tape and the label on the conveyor belt to pass through the gap between the fifth roller and the conveyor belt from front to back, so that the label on the conveyor belt is pressed and adhered to the bottom paper tape. In the case of non-separate die-cutting of label tape, the label tape released by the unwinding mechanism can first pass through the gap between the fifth roller and the conveyor belt, and the conveyor belt supports the label tape and moves forward synchronously with it.

[0011] The dual-process laser die-cutting equipment according to an embodiment of the present invention further includes a third roller and a fourth roller, both of which are mounted on the frame. The third roller is located above the front end of the conveyor belt, and the fourth roller is located above the conveyor belt and behind the third roller. In the process of separating and die-cutting label tape, the peeling mechanism is the fourth roller. The face paper tape, after being separated from the back paper tape, is first wound around the third roller. The third roller guides the face paper tape into the conveyor belt with the adhesive layer of the face paper tape facing upwards. The conveyor belt supports the face paper tape and moves backwards synchronously with it. The laser... The die-cutting mechanism laser-cuts labels and waste tape from the face paper tape on the conveyor belt. The conveyor belt supports and conveys the cut labels backward. The fourth roller guides the waste tape to peel off from the conveyor belt. In non-separable die-cutting of label tape, the peeling mechanism is the third roller. The label tape released by the unwinding mechanism can first pass through the gap between the fourth roller and the conveyor belt. The conveyor belt supports the label tape and moves forward synchronously with the label tape. The laser die-cutting mechanism laser-cuts labels and waste tape from the face paper tape in the label tape on the conveyor belt. The third roller guides the waste tape to peel off from the back paper tape.

[0012] According to an embodiment of the present invention, the dual-process laser die-cutting equipment further includes a first roller and a second roller, both of which are mounted on the frame. The second roller and the first roller are located on the front and rear sides above the laser die-cutting mechanism, respectively. When the label tape is die-cut in a separate manner, the label tape released by the unwinding mechanism can first pass through the separating mechanism. The separating mechanism separates the face paper tape and the back paper tape in the label tape. The face paper tape is sequentially wound around the first roller, the second roller, and the third roller. The conveyor belt supports the face paper tape and moves backward synchronously with the face paper tape.

[0013] According to an embodiment of the present invention, the dual-process laser die-cutting equipment includes a fourth roller body comprising a roller section, multiple rolling components, and multiple elastic components. During the separate die-cutting of label tape, the outer wall of the roller section can be wound around a waste tape. The multiple rolling components are movably connected to the roller section via the elastic components, allowing each rolling component to approach or move away from the outer wall of the roller section. The multiple rolling components are circumferentially distributed along the axis of the roller section. The multiple elastic components are respectively used to drive the multiple rolling components away from the outer wall of the roller section. The roller section is rotatably connected to the frame, enabling the multiple rolling components to sequentially roll the label between the roller section and the conveyor belt, and to peel the waste tape from the label.

[0014] According to an embodiment of the dual-process laser die-cutting equipment of the present invention, the fourth roller further includes an adjustment component, an installation cavity is formed in the roller, the adjustment component is disposed in the installation cavity, and the adjustment component is used to adjust the compression degree of the plurality of elastic components so that the rolling force applied to the label by the plurality of rolling components can be adjusted.

[0015] According to an embodiment of the present invention, the dual-process laser die-cutting equipment includes an adjusting assembly comprising a cam, a rotating shaft, two mounting plates, multiple push plates, and multiple tension springs. Both mounting plates are connected to the inner wall of the mounting cavity. The left and right ends of the multiple push plates are slidably connected to the two mounting plates, respectively. The multiple push plates are circumferentially distributed along the axis of the roller section. One end of each of the multiple elastic components abuts against multiple rolling components, and the other end of each of the multiple elastic components abuts against multiple push plates. The axis of the rotating shaft coincides with the axis of the roller section and is rotatably connected to one of the rollers. On the mounting plate, the cam is located within the area enclosed by the multiple push plates and connected to the rotating shaft. One end of each of the multiple tension springs is connected to one of the multiple push plates, and the other end of each of the multiple tension springs is connected to one of the mounting plates. The multiple tension springs are used to drive the multiple push plates closer to each other so that the multiple push plates are in contact with the cam. The rotating cam can drive the multiple push plates closer to or further away from each other, so that the compression degree of the multiple elastic components is reduced or increased, and the rolling force applied to the label by the multiple rolling components is reduced or increased.

[0016] According to an embodiment of the present invention, the dual-process laser die-cutting equipment includes a rolling assembly comprising multiple guide cylinders and multiple pressure blocks, and an elastic assembly comprising multiple compression springs. The multiple guide cylinders are evenly distributed on the outer wall of the roller in a left-right direction, and each of the multiple guide cylinders communicates with the mounting cavity. The multiple pressure blocks are slidably disposed within the multiple guide cylinders, so that each of the multiple pressure blocks can approach or move away from the outer wall of the roller. One end of each of the multiple compression springs abuts against the multiple pressure blocks, and the other end of each of the multiple compression springs abuts against the push plate. The multiple compression springs are in a compressed state, and each of the multiple compression springs is used to drive the multiple pressure blocks away from the outer wall of the roller. The multiple pressure blocks are used to roll the label between the roller and the conveyor belt.

[0036] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0037] refer to Figures 1 to 4This invention discloses a dual-process laser die-cutting equipment, including a frame 100. The frame 100 is equipped with an unwinding mechanism 110, a separating mechanism, a conveyor belt 120, a laser die-cutting mechanism 140, a peeling mechanism, a pressing mechanism, and a rewinding mechanism 130. The unwinding mechanism 110 releases the label material tape 10; the separating mechanism separates the face paper tape 11 and the back paper tape 12 from each other in the label material tape 10; the conveyor belt 120 supports the face paper tape 11 and moves synchronously with it; and the laser die-cutting... Mechanism 140 is used to laser cut labels 14 and waste tape 13 from the face paper tape 11 in the label tape 10 or the face paper tape 11 on the conveyor belt 120. The conveyor belt 120 can support and transport the cut labels 14. The peeling mechanism can peel the waste tape 13 from the back paper tape 12 or the conveyor belt 120. The pressing mechanism is used to press and adhere the labels 14 on the conveyor belt 120 to the back paper tape 12. The winding mechanism 130 is used to wind up the back paper tape 12 with the labels 14 attached. The label tape 10 released by the unwinding mechanism 110 first passes through the separation mechanism, which separates the face paper tape 11 and the back paper tape 12 in the label tape 10. The conveyor belt 120 supports the face paper tape 11 and moves synchronously with it. The laser die-cutting mechanism 140 laser-cuts the face paper tape 11 on the conveyor belt 120 to produce labels 14 and waste tape 13. The conveyor belt 120 supports and conveys the cut labels 14. The peeling mechanism peels the waste tape 13 off the conveyor belt 120. The pressing mechanism presses and adheres the labels 14 on the conveyor belt 120. On the base paper tape 12, the winding mechanism 130 winds up the base paper tape 12 with the label 14 attached to it to complete the separate die-cutting of the label material tape 10; the label material tape 10 released by the unwinding mechanism 110 can directly pass through the laser die-cutting mechanism 140, the laser die-cutting mechanism 140 laser cuts the label 14 and waste tape 13 from the face paper tape 11 in the label material tape 10, the peeling mechanism peels the waste tape 13 from the base paper tape 12, and the winding mechanism 130 winds up the base paper tape 12 with the label 14 attached to it to complete the non-separate die-cutting of the label material tape 10.

[0038] Understandably, during the separate die-cutting of the label tape, the unwinding mechanism 110 releases the label tape 10, maintaining the initial adhesion between the face paper tape 11 and the back paper tape 12. The label tape 10 then enters the separating mechanism, separating the face paper tape 11 from the back paper tape 12. The back paper tape 12 is conveyed separately, while the face paper tape 11 is supported by the conveyor belt 120. The conveyor belt 120 supports the face paper tape 11 and moves synchronously. The laser die-cutting mechanism 140 performs laser cutting on the face paper tape 11 on the conveyor belt 120. The label 14 and waste tape 13 are formed. The cut label 14 is still supported and transported by the conveyor belt 120. Then the peeling mechanism peels and processes the waste tape 13 from the conveyor belt 120. Next, the conveyor belt 120 transports the label 14 to the pressing mechanism. The backing paper tape 12 also arrives at the same time. The pressing mechanism presses and adheres the label 14 to the backing paper tape 12. Finally, the backing paper tape 12 with the label 14 is wound up by the winding mechanism 130 to complete the separate die-cutting of the label tape 10. In the non-separable die-cutting of label tape, the unwinding mechanism 110 releases the label tape 10 while maintaining the front paper tape 11 and back paper tape 12 in a non-separated state and conveys it directly. The label tape 10 then passes under the laser die-cutting mechanism 140, which only laser-cuts the front paper tape 11, forming the label 14 and waste tape 13 without damaging the back paper tape 12. The die-cut label tape 10 then enters the peeling mechanism, which peels the waste tape 13 from the back paper tape 12 and processes it. Finally, the back paper tape 12 with the label 14 attached is wound up by the winding mechanism 130, completing the non-separable die-cutting of the label tape 10. This dual-process laser die-cutting equipment, through its reasonable structural design, can achieve both separable and non-separable die-cutting of the label tape 10. When separate die-cutting is required, the label tape 10 can be processed according to the corresponding feeding sequence and processing steps; when non-separate die-cutting is required, it can also be operated through the corresponding process, so that enterprises no longer need to purchase two types of equipment separately. Only one dual-process laser die-cutting equipment can meet different die-cutting processing needs, which not only helps to reduce the enterprise's equipment procurement costs, but also saves workshop floor space.

[0039] In the separate die-cutting process, the label tape 10 is first separated into a face paper tape 11 and a back paper tape 12 at the separation mechanism. The face paper tape 11 is stably supported by the conveyor belt 120 along an independent path. The laser die-cutting mechanism 140 cuts the face paper tape 11 only. At this time, the face paper tape 11 is wrinkle-free and the cutting parameters can be precisely optimized, avoiding white or yellow edges caused by tape shaking or energy runaway. In addition, the laser cutting is on the back of the material, which will not directly burn the printed surface and cause white or yellow edges. The back paper tape 12 moves along another independent path and does not pass through the laser die-cutting area. The laser energy only acts on the face paper tape 11, thus completely eliminating laser burning marks. Finally, the label 14 and the back paper tape 12 are accurately bonded through the pressing mechanism, completing the defect-free die-cutting process.

[0040] It should be noted that backing paper strip 12 is glassine paper, which has a smooth and flat surface. (Reference) Figure 10 The laser die-cutting mechanism 140 can laser-cut the face paper tape 11 along a preset path. The face paper tape 11 within the cutting area becomes the label 14, and the remaining part becomes the waste tape 13, thus forming the face paper tape 11 into waste tape 13 and multiple labels 14. In this embodiment of the invention, the back side of the face paper tape 11 refers to the side of the face paper tape 11 away from the adhesive layer. It should be explained that when performing separate die-cutting on the label material tape 10, the parameters of the laser die-cutting mechanism 140 are adjusted to cut only the face paper tape 11 without cutting the conveyor belt 120; when performing non-separate die-cutting on the label material tape 10, the parameters of the laser die-cutting mechanism 140 are adjusted to cut only the face paper tape 11 without cutting the bottom paper tape 12.

[0041] refer to Figure 3 and Figure 4 The dual-process laser die-cutting equipment also includes two sixth rollers 300, which are arranged vertically on the frame 100 and positioned between the unwinding mechanism 110 and the conveyor belt 120. In the case of separate die-cutting of label tape, the separation mechanism consists of two sixth rollers 300. The label tape 10 released by the unwinding mechanism 110 first enters the gap between the two sixth rollers 300, and the two sixth rollers 300 respectively guide the face paper tape 11 and the back paper tape 12 in the label tape 10 to separate from each other. In the case of non-separate die-cutting of label tape, a guide channel is formed between the two sixth rollers 300. The label tape 10 released by the unwinding mechanism 110 first passes through the guide channel and then passes through the laser die-cutting mechanism 140.

[0042] Understandably, in the case of separate die-cutting of label tape, the separation mechanism consists of two sixth rollers 300. The label tape 10 released by the unwinding mechanism 110 first enters the gap between the two sixth rollers 300, and the face paper tape 11 and the back paper tape 12 of the label tape 10 are respectively wound around the upper and lower sixth rollers 300. The two sixth rollers 300 guide the face paper tape 11 and the back paper tape 12, respectively, so that the conveying directions of the face paper tape 11 and the back paper tape 12 are different, thereby causing the face paper tape 11 and the back paper tape 12 to separate at the two sixth rollers 300. In the case of non-separate die-cutting of label tape, the label tape 10 released by the unwinding mechanism 110 first passes through the guide channel, that is, the two sixth rollers 300 can guide the label tape 10, so that the label tape 10 can be smoothly conveyed forward. On the other hand, the two sixth rollers 300 can limit the label strip 10 in the vertical direction to prevent the label strip 10 from shaking up and down during the conveying process, and ensure that the laser die-cutting mechanism 140 can smoothly laser cut the face paper strip 11 in the label strip 10.

[0043] refer to Figure 3 and Figure 4 The dual-process laser die-cutting equipment also includes a fifth roller 200, which is mounted on the frame 100 and located above the rear end of the conveyor belt 120. In the case of separate die-cutting of label tape, the pressing mechanism is the fifth roller 200. The bottom paper tape 12 is first wound around the fifth roller 200. The fifth roller 200 guides the bottom paper tape 12 and the label 14 on the conveyor belt 120 to pass through the gap between the fifth roller 200 and the conveyor belt 120 from front to back, so that the label 14 on the conveyor belt 120 is pressed and bonded to the bottom paper tape 12. In the case of non-separate die-cutting of label tape, the label tape 10 released by the unwinding mechanism 110 can first pass through the gap between the fifth roller 200 and the conveyor belt 120. The conveyor belt 120 supports the label tape 10 and moves forward synchronously with the label tape 10.

[0044] Understandably, in the separate die-cutting of label tape, after the backing paper tape 12 and the face paper tape 11 separate, the backing paper tape 12 wraps around the fifth roller 200. The fifth roller 200 guides the backing paper tape 12, allowing it to pass between the fifth roller 200 and the conveyor belt 120, thus pressing and adhering the label 14 on the conveyor belt 120 onto the backing paper tape 12. In the non-separate die-cutting of label tape, the label tape 10 released by the unwinding mechanism 110 can first pass through the gap between the fifth roller 200 and the conveyor belt 120. The fifth roller 200 guides the label tape 10, allowing it to be smoothly supported by the conveyor belt 120, thus ensuring stable transport of the label tape 10 and enabling the laser die-cutting mechanism 140 to smoothly laser-cut the face paper tape 11 in the label tape 10.

[0045] refer to Figure 3 and Figure 4The dual-process laser die-cutting equipment also includes a third roller 600 and a fourth roller 700, both mounted on the frame 100. The third roller 600 is located above the front end of the conveyor belt 120, and the fourth roller 700 is located above the conveyor belt 120 and behind the third roller 600. During the separate die-cutting of the label tape, the peeling mechanism is the fourth roller 700. The face paper tape 11, after separating from the base paper tape 12, is first wound around the third roller 600. The third roller 600 guides the face paper tape 11 into the conveyor belt 120 with the adhesive layer of the face paper tape 11 facing upwards. The conveyor belt 120 supports the face paper tape 11 and moves backwards synchronously with it. The laser die-cutting mechanism 140 controls the conveyor belt... The face paper tape 11 on 120 is laser-cut into label 14 and waste tape 13. The conveyor belt 120 supports and conveys the cut label 14 backward. The fourth roller 700 guides the waste tape 13 to peel off from the conveyor belt 120. In non-separable die-cutting of label tape, the peeling mechanism is the third roller 600. The label tape 10 released by the unwinding mechanism 110 can pass through the gap between the fourth roller 700 and the conveyor belt 120. The conveyor belt 120 supports the label tape 10 and moves forward synchronously with the label tape 10. The laser die-cutting mechanism 140 laser-cuts the face paper tape 11 in the label tape 10 on the conveyor belt 120 into label 14 and waste tape 13. The third roller 600 guides the waste tape 13 to peel off from the back paper tape 12.

[0046] Understandably, in the separate die-cutting of label strips, the peeling mechanism is the fourth roller 700. After the face paper strip 11 and the back paper strip 12 separate, the face paper strip 11 is wound around the third roller 600. The third roller 600 guides the face paper strip 11, allowing it to be supported by the conveyor belt 120 and move backward together with it. The laser die-cutting mechanism 140 laser-cuts the face paper strip 11 on the conveyor belt 120 into label 14 and waste strip 13. Then, the label strip 10 is wound around the fourth roller 700. The fourth roller 700 guides the waste strip 13, changing its conveying direction and thus peeling it off from the label 14 and the conveyor belt 120. In the non-separable die-cutting of label tape, the peeling mechanism is the third roller 600. The label tape 10 released by the unwinding mechanism 110 can first pass through the gap between the fourth roller 700 and the conveyor belt 120. The fourth roller 700 plays a limiting role in the label tape 10, preventing the label tape 10 from shaking in the up and down direction. After the laser die-cutting mechanism 140 laser-cuts the face paper tape 11 of the label tape 10 on the conveyor belt 120 into label 14 and waste tape 13, the waste tape 13 is wound around the third roller 600. The third roller 600 plays a guiding role in the waste tape 13, which changes the conveying direction of the waste tape 13, thereby causing the waste tape 13 to peel off from the back paper tape 12.

[0047] refer to Figures 1 to 4 In a preferred embodiment of the present invention, the dual-process laser die-cutting equipment further includes a first roller 400, a second roller 500, a third roller 600, a fourth roller 700, and a waste collection mechanism 150. The pressing mechanism includes a fifth roller 200, and the separating mechanism includes two sixth rollers 300. The unwinding mechanism 110, the conveyor belt 120, and the winding mechanism 130 are arranged from back to front on the frame 100. The conveyor belt 120 is parallel to the front-back direction. The laser die-cutting mechanism 140 is located above the middle of the conveyor belt 120, and the waste collection mechanism 150 is located above the rear end of the conveyor belt 120 and behind the laser die-cutting mechanism 140. The waste collection mechanism 150 is used to wind up the waste material belt 13. The first roller 400 and the second roller 500 are both positioned above the laser die-cutting mechanism 140 and the waste collection mechanism 150. The first roller 400 is positioned behind the waste collection mechanism 150, and the second roller 500 is positioned in front of the laser die-cutting mechanism 140. The third roller 600 is positioned above the front end of the conveyor belt 120, and its outer wall is tangent to the upper surface of the conveyor belt 120. The fifth roller 200 is positioned above the rear end of the conveyor belt 120, and is positioned between the conveyor belt 120 and the waste collection mechanism 150. The fourth roller 700 is positioned between the fifth roller 200 and the third roller 600, and is positioned between the conveyor belt 120 and the waste collection mechanism 150. Two sixth rollers 300 are evenly distributed vertically on the frame 100, and are positioned between the unwinding mechanism 110 and the conveyor belt 120.

[0048] The gap between the two sixth rollers 300 allows the label material strip 10 to pass through. The upper and lower sixth rollers 300 allow the face paper strip 11 and the back paper strip 12 of the label material strip 10 to be wound around, respectively. The fifth roller 200 allows the back paper strip 12 to be wound around. The gap between the fifth roller 200 and the conveyor belt 120 allows the label 14 and the back paper strip 12 to pass through. The gap between the fifth roller 200 and the conveyor belt 120 allows the label material strip 10 to pass through. The gap between the fourth roller 700 and the conveyor belt 120 allows the label 14 and the waste material strip 13 to pass through. The fourth roller 700 allows the waste material strip 13 to be wound around. The gap between the fourth roller 700 and the conveyor belt 120 allows the label material strip 10 to pass through.

[0049] refer to Figure 2 and Figure 3In the process of separating and die-cutting label tape, the unwinding mechanism 110 releases the label tape 10 from back to front. The label tape 10 first moves to the gap between the two sixth rollers 300, and the face paper tape 11 and the back paper tape 12 in the label tape 10 are respectively wound around the upper and lower sixth rollers 300 to change the conveying direction of the face paper tape 11 and the back paper tape 12. This causes the face paper tape 11 and the back paper tape 12 in the label tape 10 to separate at the two sixth rollers 300. Then, the back paper tape 12 is wound around the fifth roller 200, and the face paper tape 11 is wound around the first roller 400, the second roller 500, and the third roller 600 in sequence. The third roller 600 changes the conveying direction of the face paper tape 11, so that the conveyor belt 120 supports the face paper tape 11 and moves backward synchronously with the face paper tape 11. At this time, the adhesive layer of the face paper tape 11 on the conveyor belt 120 faces upward. The laser die-cutting mechanism 140 laser-cuts the face paper strip 11 on the conveyor belt 120, cutting it into waste strip 13 and labels 14. The conveyor belt 120 then supports and conveys the cut labels 14 backwards. The waste strip 13 and labels 14 on the conveyor belt 120 pass through the gap between the fourth roller 700 and the conveyor belt 120, with the waste strip 13 wrapped around the fourth roller 700. The fourth roller 700 changes the conveying direction of the waste strip 13, causing it to peel off from the conveyor belt 120 and the labels 14, allowing the waste collection mechanism 150 to rewind the waste strip 13. The labels 14 remain on the conveyor belt 120, which continues to convey them from back to front. The bottom paper strip 12 is wrapped around the fifth roller 200, passing through the gap between the fifth roller 200 and the conveyor belt 120. Under the conveying action of the conveyor belt 120, the label 14 moves into the gap between the fifth roller and the conveyor belt 120. The adhesive layer of the label 14 can abut against the bottom paper tape 12 wrapped on the fifth roller body 200, so that the label 14 is pressed and bonded to the bottom paper tape 12. Then, the winding mechanism 130 can wind up the bottom paper tape 12 with the label 14 bonded to it, so as to complete the separate die-cutting of the label material tape 10.

[0050] refer to Figure 4In the non-separable die-cutting of label tape, the unwinding mechanism 110 releases the label tape 10 from back to front. The label tape 10 first passes through the gap between the two sixth rollers 300 and moves to the conveyor belt 120, so that the conveyor belt 120 supports the label tape 10 and moves forward synchronously with the label tape 10, and the label tape 10 passes through the gap between the fourth roller 700 and the conveyor belt 120. The laser die-cutting mechanism 140 can laser cut only the face paper tape 11 of the label tape 10 on the conveyor belt 120, so that the face paper tape 11 is cut into waste tape 13 and label 14, and then the conveyor belt 120 supports and conveys the cut label 14 backward. Waste tape 13 is sequentially wound around the third roller 600, the second roller 500 and the first roller 400 to change the conveying direction of waste tape 13, so that the conveying direction of waste tape 13 and label 14 is different, thereby causing waste tape 13 to peel off from label 14 and backing paper tape 12. Waste collection mechanism 150 winds up waste tape 13 and winding mechanism 130 winds up backing paper tape 12 with label 14 attached, so as to complete the non-separation die-cutting of label tape 10.

[0051] refer to Figure 4 In non-separable die-cutting of label tape, the label tape 10 passes sequentially through the gap between the two sixth rollers 300 and the gap between the fourth roller 700 and the conveyor belt 120. This allows the sixth rollers 300 and the fourth roller 700 to limit the label tape 10, preventing it from swaying vertically during movement. This ensures that the subsequent laser die-cutting mechanism 140 can accurately laser-cut the face paper strip 11 within the label tape 10, avoiding processing errors caused by label tape 10 misalignment. In non-separable die-cutting of label tape, the conveyor belt 120 supports the label tape 10 and moves forward synchronously with it. The conveyor belt 120 keeps the label tape 10 stable during cutting, ensuring the quality of laser cutting. In this embodiment, the unwinding mechanism 110, the winding mechanism 130, the laser die-cutting mechanism 140, and the waste collection mechanism 150 are all common mechanisms in the field of label tape die-cutting, and will not be further described here.

[0052] In this embodiment of the invention, the conveyor belt 120 is an adsorption conveyor belt. During the separate die-cutting of the label material, as the adsorption conveyor belt supports and moves backward synchronously with the face paper belt 11, it continuously adsorbs the face paper belt 11. When the waste collection mechanism 150 winds up the waste material belt 13, the waste material belt 13 is peeled off from the label 14 and the adsorption conveyor belt. The label 14 is then adsorbed and remains on the adsorption conveyor belt, allowing it to be conveyed backward to the fifth roller 200 to complete the pressing and bonding of the base paper belt 12 and the label 14. Similarly, during the non-separate die-cutting of the label material, the adsorption conveyor belt can adsorb, support, and move forward synchronously with the label material belt 10, ensuring the label material belt 10 remains stable and does not shake. Further details are omitted here.

[0053] refer to Figure 1 and Figure 2 The dual-process laser die-cutting equipment also includes a first correction mechanism 160, which is mounted on the frame 100 and located between the unwinding mechanism 110 and the conveyor belt 120. In the separate die-cutting of label tape, the label tape 10 unwound from the unwinding mechanism 110 is wound around the first correction mechanism 160 and then moved to the two sixth rollers 300. The first correction mechanism 160 can correct the label tape 10 in the left-right direction to prevent it from shifting during movement, ensuring that the label tape 10 is smoothly and accurately conveyed along a preset path. This allows the subsequent laser die-cutting mechanism 140 to accurately die-cut the paper tape 11, avoiding processing errors caused by label tape 10 shifting. Similarly, in the non-separate die-cutting of label tape, the label tape 10 unwound from the unwinding mechanism 110 is wound around the first correction mechanism 160 and then passed between the two sixth rollers 300.

[0054] refer to Figure 1 and Figure 2 The dual-process laser die-cutting equipment also includes a second correction mechanism 170, which is mounted on the frame 100 and located below the conveyor belt 120 and the sixth roller 300. During the separate die-cutting of the label material, the base paper tape 12 is first wound around the second correction mechanism 170, and then around the fifth roller 200. This allows the second correction mechanism 170 to correct the base paper tape 12 in the left-right direction, ensuring that the base paper tape 12 can be smoothly and accurately conveyed along the preset path, guaranteeing that the subsequent label 14 can be accurately pressed and adhered to the base paper tape 12. The first correction mechanism 160 and the second correction mechanism 170 are common adjustment mechanisms in film material conveying equipment. They typically consist of sensors and actuators, and can dynamically calibrate the conveying of film materials to ensure that the film materials can move accurately along the preset path. Further details are omitted here.

[0055] In the prior art, during the laser die-cutting process, the label 14 needs to be cut from the face paper tape 11, which may result in tiny connection residues (such as incompletely cut adhesive layers or fibers) at the cut edge between the waste tape 13 and the label 14. As the waste tape 13 wound on the fourth roller 700 is wound by the waste collection mechanism 150, the connection residues will drag the label 14, causing the label 14 to be easily wound by the waste collection mechanism 150 along with the waste tape 13, thus reducing the processing quality of the laser die-cutting equipment.

[0056] refer to Figures 5 to 10 In another embodiment of the present invention, the fourth roller body 700 includes a roller portion 710, a plurality of rolling components 720 and a plurality of elastic components 730. When the label tape is die-cut separately, the outer wall of the roller portion 710 can be wound around the waste tape 13. The plurality of rolling components 720 are movably connected to the roller portion 710 through the elastic components 730 so that the plurality of rolling components 720 can approach or move away from the outer wall of the roller portion 710. The plurality of rolling components 720 are circumferentially distributed along the axis of the roller portion 710. The plurality of elastic components 730 are respectively used to drive the plurality of rolling components 720 away from the outer wall of the roller portion 710. The roller portion 710 is rotatably connected to the frame 100 so that the plurality of rolling components 720 can sequentially roll the label 14 between the roller portion 710 and the conveyor belt 120, and peel the waste tape 13 off from the label 14 and the conveyor belt 120. It should be explained that during the separate die-cutting of the label strip, the laser die-cutting mechanism 140 can laser-cut the face paper strip 11 moving from front to back on the conveyor belt 120, so that multiple rows of labels 14 are evenly distributed on the conveyor belt 120 in the front-back direction, and each row of labels 14 includes multiple labels 14 evenly distributed in the left-right direction. Under the conveying action of the conveyor belt 120, the multiple rows of labels 14 move backward sequentially between the fourth roller 700 and the conveyor belt 120, that is, multiple labels 14 in the same left-right direction can move simultaneously between the fourth roller 700 and the conveyor belt 120. In this embodiment of the invention, the dual-process laser die-cutting equipment also includes a motor (not shown in the figure) mounted on the frame 100, the output end of the motor is connected to the roller 710, and the motor is used to drive the roller 710 to rotate around its own axis.

[0057] Understandably, during the separate die-cutting of label strips, the conveyor belt 120 transports labels 14 backward, causing multiple rows of labels 14 in the same left-right direction to move sequentially backward between the roller section 710 and the conveyor belt 120. The outer wall of the roller section 710 is used for the waste strip 13 to be wound around, so that the waste strip 13 separates from the labels 14 at the roller section 710 and is wound up by the waste collection device. During the rotation of the roller section 710, the rolling assembly 720 on the roller section 710 can simultaneously abut against the multiple labels 14 between the roller section 710 and the conveyor belt 120. As the roller section 710 rotates, the elastic assembly 730 begins to compress and the rolling assembly 720 approaches the outer wall of the roller section 710. Under the pushing force of the elastic component 730 and with the cooperation of the roller 710 and the conveyor belt 120, the rolling component 720 can roll the multiple labels 14 between the roller 710 and the conveyor belt 120, forcing the waste tape 13 to peel off from the multiple labels 14, causing the connection residue between the labels 14 and the waste tape 13 to break, preventing the labels 14 from being wound up by the waste collection mechanism 150 along with the waste tape 13, thus ensuring the processing quality of the dual-process laser die-cutting equipment. Matching the rotational speed of the roller 710 with the conveying speed of the conveyor belt 120 allows the multiple rolling components 720 on the roller 710 to sequentially roll the multiple labels 14 between the roller 710 and the conveyor belt 120.

[0058] refer to Figures 6 to 8 The fourth roller body 700 also includes an adjustment component 740. A mounting cavity is formed within the roller portion 710, and the adjustment component 740 is disposed within the mounting cavity. The adjustment component 740 is used to adjust the compression degree of the multiple elastic components 730, so that the rolling pressure applied to the label 14 by the multiple rolling components 720 can be adjusted. It is understood that the thickness of the face paper strip 11 varies with different specifications of label material strip 10, resulting in different thicknesses of the cut labels 14. The adjustment component 740 can adjust the compression degree of the multiple elastic components 730. The greater the compression degree of the elastic component 730, the greater the pushing force it applies to the rolling component 720, allowing the pushing force applied by the elastic component 730 to the rolling component 720 to be adjusted, thereby allowing the rolling pressure of the rolling component 720 on the label 14 to be adjusted. For thicker face paper strip 11, the compression degree of the elastic component 730 can be increased, thereby increasing the rolling pressure of the rolling component 720 on the label 14. For the thinner face paper tape 11, the compression degree of the elastic component 730 can be adjusted to reduce the rolling pressure of the roller assembly 720 on the label 14. The adjustment component 740 can adjust the rolling pressure of the roller assembly 720 on the label 14, so that the roller assembly 720 can match the thickness characteristics of the label tape 10, improving the operational flexibility of the fourth roller body 700.

[0059] refer to Figure 7 and Figure 9The adjusting assembly 740 includes a cam 741, a rotating shaft 742, two mounting plates 743, multiple push plates 744, and multiple tension springs 745. Both mounting plates 743 are connected to the inner wall of the mounting cavity. The left and right ends of the multiple push plates 744 are slidably connected to the two mounting plates 743, respectively. The multiple push plates 744 are circumferentially distributed along the axis of the roller section 710. One end of each of the multiple elastic components 730 abuts against multiple rolling components 720, and the other end of each elastic component 730 abuts against multiple push plates 744. The axis of the rotating shaft 742 coincides with the axis of the roller section 710 and is rotatably connected to one of the mounting plates 745. On the 3rd floor, the cam 741 is located in the area enclosed by multiple push plates 744 and is connected to the rotating shaft 742. One end of multiple tension springs 745 is connected to multiple push plates 744 respectively, and the other end of multiple tension springs 745 is connected to one of the mounting plates 743. The multiple tension springs 745 are used to drive the multiple push plates 744 to move closer to each other so that the multiple push plates 744 are all in contact with the cam 741. The rotating cam 741 can drive the multiple push plates 744 to move closer to each other or further away from each other, so that the compression degree of multiple elastic components 730 is reduced or increased, and the rolling force applied by multiple rolling components 720 to the label 14 is reduced or increased.

[0060] Understandably, under the tension of multiple tension springs 745, multiple push plates 744 remain in contact with cam 741. When it is necessary to increase the compression of multiple elastic components 730, the worker can rotate the shaft 742 forward and drive the cam 741 to rotate. The rotating cam 741 can simultaneously push multiple push plates 744, causing the multiple push plates 744 to move away from each other. Since one end of each elastic component 730 is in contact with multiple rolling components 720, and the other end of each elastic component 730 is in contact with multiple push plates 744, after the multiple push plates 744 move away from each other, the multiple push plates 744 can push multiple elastic components 730 respectively, thereby increasing the compression of multiple elastic components 730, which increases the rolling pressure of multiple rolling components 720 on label 14. When the compression degree of multiple elastic components 730 needs to be reduced, the worker can rotate the shaft 742 in the opposite direction and drive the cam 741 to rotate. Since the multiple push plates 744 are in contact with the cam 741, the multiple push plates 744 move closer to each other. Since one end of each elastic component 730 is in contact with multiple rolling components 720, and the other end of each elastic component 730 is in contact with multiple push plates 744, after the multiple push plates 744 move closer to each other, the multiple elastic components 730 begin to extend, thereby reducing the compression degree of the multiple elastic components 730 and reducing the rolling pressure of the multiple rolling components 720 on the label 14.

[0061] This example uses one of the push plates, 744, for illustration. (Refer to...) Figure 6 and Figure 7The push plate 744 has two guide rods 747 at both its left and right ends. Each of the two mounting plates 743 has two oblong holes 748 corresponding to the push plate 744. The two guide rods 747 at the left end of the push plate 744 pass through the two oblong holes 748 on the left mounting plate 743, and the two guide rods 747 at the right end of the push plate 744 pass through the two oblong holes 748 on the right mounting plate 743, allowing the push plate 744 to slide relative to the two mounting plates 743. Further details are omitted here. One end of the rotating shaft 742 is rotatably connected to one of the mounting plates 743, and the other end is rotatably connected to the other mounting plate 743. The middle part of the rotating shaft 742 passes through the area formed by the multiple push plates 744. One end of the rotating shaft 742 is provided with a gripping part, and the other end of the rotating shaft 742 is provided with a stud 749. A fastener is threaded onto the stud 749, which can press against another mounting plate 743 to restrict the rotation of the rotating shaft 742 relative to the two mounting plates 743. It can be understood that when the fastener is tightened, the rotating shaft 742 and the cam 741 remain stationary relative to the two mounting plates 743 to prevent the push plate 744 from moving relative to the mounting plate 743 during the rotation of the roller 710. The fastener can be loosened when the rolling pressure of the rolling assembly 720 needs to be adjusted. Each of the two mounting plates 743 has a mounting sleeve 746 on its opposite side, and the rotating shaft 742 passes through the two mounting sleeves 746. The left ends of the multiple push plates 744 are connected to the mounting sleeves 746 on the left mounting plate 743 via tension springs 745, and the right ends of the multiple push plates 744 are connected to the mounting sleeves 746 on the right mounting plate 743 via tension springs 745.

[0062] refer to Figure 6 , Figure 8 and Figure 9The rolling assembly 720 includes multiple guide cylinders 721 and multiple pressure blocks 723. The elastic assembly 730 includes multiple compression springs 731. The multiple guide cylinders 721 are evenly distributed on the outer wall of the roller section 710 in the left-right direction. The multiple guide cylinders 721 are all in communication with the mounting cavity. The multiple pressure blocks 723 are slidably disposed in the multiple guide cylinders 721 so that the multiple pressure blocks 723 can approach or move away from the outer wall of the roller section 710. One end of the multiple compression springs 731 abuts against the multiple pressure blocks 723, and the other end of the multiple compression springs 731 abuts against the push plate 744. The multiple compression springs 731 are all in a compressed state. The multiple compression springs 731 are used to drive the multiple pressure blocks 723 away from the outer wall of the roller section 710. The multiple pressure blocks 723 are used to roll the label 14 between the roller section 710 and the conveyor belt 120. Here, we take one of the cooperating guide cylinders 721, pressure blocks 723 and compression springs 731 as an example for illustration. During the rotation of the roller 710, the pressure block 723 abuts against the label 14. The pressure block 723 moves within the guide cylinder 721 and approaches the surface of the roller 710, causing the compression spring 731 to compress. Under the pushing force of the compression spring 731, the pressure block 723 presses against the label 14. As the roller 710 rotates, the pressure block 723 completes the rolling of the label 14. Further details are omitted here. In this embodiment of the invention, the pressure block 723 has an arc surface, which allows it to roll the label 14.

[0063] It should be explained that the guide cylinder 721 and the pressure block 723 can extend into the holes on the waste belt 13, and as the roller 710 rotates, the guide cylinder 721 and the pressure block 723 can be pulled out from the holes on the waste belt 13, allowing the waste belt 13 to wrap around the outer wall of the roller 710, thereby enabling the outer wall of the roller 710 to exert a traction effect on the waste belt 13. Here, we take one of the cooperating components—the guide cylinder 721, the pressure block 723, and the compression spring 731—as an example. A limiting step 722 is formed inside the guide cylinder 721, and a limiting flange 724 is provided on the outer wall of the pressure block 723. Under the action of the compression spring 731, the limiting flange 724 can abut against the limiting step 722, thereby preventing the pressure block 723 from dislodging from the guide cylinder 721 in a direction away from the outer wall of the roller 710. The compression spring 731 is in a compressed state, so under the pushing action of the compression spring 731, the limiting flange 724 on the pressure block 723 abuts against the limiting step 722 inside the guide cylinder 721. After the multiple push plates 744 move away from each other under the action of the cam 741, the compression degree of the compression spring 731 increases, and the rolling force of the pressure block 723 on the label 14 increases; after the multiple push plates 744 move closer to each other under the action of the cam 741, the compression degree of the compression spring 731 decreases, and the rolling force of the pressure block 723 on the label 14 decreases, which will not be further elaborated here. Multiple limiting sleeves are evenly distributed on the push plate 744 in the left-right direction. The multiple limiting sleeves are used for the other end of multiple compression springs 731 to extend into, so that the limiting sleeves can limit and guide the compression springs 731.

[0064] In this embodiment of the invention, both ends of the roller 710 are connected to detachable end caps. The roller 710 is rotatably connected to the frame 100 via the two end caps, and both end caps can be removed from the frame 100. When the adjustment assembly 740 needs to be operated, the worker can first remove the two end caps from the frame 100, and then remove the two end caps from the roller 710, allowing the worker to reach into the mounting cavity on the roller 710 and rotate the rotating shaft 742. End caps are a common feature in roller technology and will not be described further here.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.

In non-separable die-cutting of label tape, the label tape released by the unwinding mechanism can first pass through the gap between the fifth roller and the conveyor belt, and the conveyor belt supports the label tape and moves forward synchronously with the label tape.

4. The dual-process laser die-cutting equipment according to claim 1, characterized in that: It also includes a first roller and a second roller, both of which are mounted on the frame. The second roller and the first roller are located on the front and rear sides above the laser die-cutting mechanism, respectively. In the process of separating and die-cutting label tape, the label tape released by the unwinding mechanism can first pass through the separating mechanism. The separating mechanism separates the face paper tape and the back paper tape in the label tape. The face paper tape is sequentially wound around the first roller, the second roller and the third roller. The conveyor belt supports the face paper tape and moves backward synchronously with the face paper tape.

5. The dual-process laser die-cutting equipment according to claim 1, characterized in that: The adjusting assembly includes a cam, a rotating shaft, two mounting plates, multiple push plates, and multiple tension springs. Both mounting plates are connected to the inner wall of the mounting cavity. The left and right ends of the multiple push plates are slidably connected to the two mounting plates, respectively. The multiple push plates are circumferentially distributed along the axis of the roller section. One end of each of the multiple elastic components abuts against the multiple rolling components, and the other end of each elastic component abuts against the multiple push plates. The axis of the rotating shaft coincides with the axis of the roller section and is rotatably connected to one of the mounting plates. A cam is located within the area enclosed by the multiple push plates and connected to the rotating shaft. One end of each of the multiple tension springs is connected to one of the multiple push plates, and the other end of each of the multiple tension springs is connected to one of the mounting plates. The multiple tension springs are used to drive the multiple push plates closer to each other so that the multiple push plates are in contact with the cam. The rotating cam can drive the multiple push plates closer to each other or further away from each other, so that the compression degree of the multiple elastic components is reduced or increased, and the rolling force applied to the label by the multiple rolling components is reduced or increased.

6. The dual-process laser die-cutting equipment according to claim 5, characterized in that: The rolling assembly includes multiple guide cylinders and multiple pressure blocks. The elastic assembly includes multiple compression springs. The multiple guide cylinders are evenly distributed on the outer wall of the roller section in the left-right direction. The multiple guide cylinders are all in communication with the mounting cavity. The multiple pressure blocks are slidably disposed in the multiple guide cylinders so that the multiple pressure blocks can be close to or away from the outer wall of the roller section. One end of the multiple compression springs abuts against the multiple pressure blocks, and the other end of the multiple compression springs abuts against the push plate. The multiple compression springs are all in a compressed state. The multiple compression springs are used to drive the multiple pressure blocks away from the outer wall of the roller section. The multiple pressure blocks are used to roll the label between the roller section and the conveyor belt.
