Description

Technical Field

[0001] This utility model relates to a waste discharge separation mechanism, and more particularly to a waste discharge separation mechanism for a die-cutting machine. Background Technology

[0002] During label production, die-cutting machines need to remove waste label material containing adhesive, that is, separate the waste portion that forms the label shape. In this process, appropriately heating and softening the adhesive on the label paper is a crucial step to ensure that the adhesive can be smoothly and completely peeled off from the backing paper.

[0003] In existing technologies, heating is often achieved by having a heating roller directly contact the label material. This method has several inherent drawbacks: First, softened adhesives easily adhere to the surface of the heating roller, requiring frequent shutdowns for cleaning, which severely impacts production efficiency; second, when dealing with label materials of varying widths, the entire heating roller is heated, leading to energy waste; third, traditional heating rollers have a fixed structure, making it difficult to quickly adjust the heating area according to the material's location, resulting in poor heating uniformity control and inconvenient maintenance and replacement.

[0004] Therefore, this utility model aims to solve the core technical problems of easy adhesion of colloids, high heating energy consumption, and inconvenient maintenance in the waste discharge heating process of existing die-cutting machines. Utility Model Content

[0005] The main purpose of this utility model is to provide a waste separation mechanism for a die-cutting machine to solve the problems raised in related technologies.

[0006] To achieve the above objectives, according to one aspect of the present invention, a waste separation mechanism for a die-cutting machine is provided, comprising a machine housing, a conveying mechanism fixedly mounted on the machine housing, the conveying mechanism including at least a rotatably mounted conveyor belt, two upright plates symmetrically fixedly mounted on the machine housing, a conveying roller rotatably mounted between the two upright plates, the conveying roller including at least a rotating roller rotatably mounted between the two upright plates, and an air plate inserted into the rotating roller, the conveying roller being used for initial heating of the label paper with adhesive, a heating roller for further heating the label paper with adhesive being rotatably mounted between the two upright plates, a plurality of heating plates being snapped into the heating roller, a plurality of sets of protrusions being fixedly mounted in a circular array on the outer wall of the heating roller, and a release transfer roller for removing the adhesive from the label paper being rotatably mounted between the two upright plates.

[0007] Furthermore, the rotating roller has an annular slot, and the rotating roller has several sets of through holes arranged in an annular array, the through holes communicating with the slot.

[0008] Furthermore, the air plate is inserted into the slot, and the insertion end of the air plate is annular. An annular slot is opened in the air plate. The air plate is arranged in an annular array with several sets of air outlets. The air outlets are connected to the slots. A column groove is also opened on the inner wall of the air plate. The rotating shaft of the rotating roller is rotatably arranged in the column groove.

[0009] Furthermore, a fan is fixedly installed on the outside of a vertical plate on the chassis, and a duct is fixedly connected to the fan. The duct is fixedly connected to the air plate, and one end of the duct is connected to the empty slot.

[0010] Furthermore, a cavity is formed inside the heating roller, and several partitions are fixedly arranged inside the cavity. A slot is formed between two adjacent partitions on the heating roller, and the heating plate is inserted into the cavity along the slot.

[0011] Furthermore, an arc-shaped fixing plate is fixedly connected to the top of the heating plate, and connecting plates are fixedly connected to both sides of the fixing plate, with elastic protrusions fixedly provided on the sidewalls of the connecting plates.

[0012] Furthermore, the heating roller has a slot on both sides of each slot that communicates with it, the connecting plate is inserted into the slot, and a groove is provided on one side of the slot.

[0013] Furthermore, the release transfer roller is coated with a fluorosilicone rubber coating, and a pressure roller is fixedly arranged between the two vertical plates, while a take-up roller for collecting the cooled colloid is rotatably arranged between the two vertical plates.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In this die-cutting machine waste separation mechanism, a multi-stage heating system consisting of non-contact hot air initial softening by conveyor rollers and contact further softening by heating rollers, combined with the Teflon coating of the release transfer roller and the protrusion design on the surface of the heating roller, significantly reduces the risk of colloid sticking to the roller surface during heating and transfer, ensuring the continuity and stability of production.

[0015] 2. In this die-cutting machine waste separation mechanism, an independent heating zone is formed by a partition set inside the heating roller, and with the independently insertable partition heating plate, the area where the label material of different widths is located can be precisely heated, avoiding energy loss in ineffective areas, realizing intensive use of energy, and effectively reducing energy consumption.

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] This embodiment provides a waste separation mechanism for a die-cutting machine, including a housing 1, which is located after the die-cutting station of the die-cutting machine; a conveying mechanism is fixedly installed on the housing 1, the conveying mechanism including at least a rotatable conveyor belt 2 for carrying and conveying label paper with adhesive; two upright plates 11 are symmetrically fixedly installed on the housing 1, and a conveying roller 3 is rotatably installed between the two upright plates 11; the conveying roller 3 includes at least a rotating roller 31 rotatably installed between the two upright plates 11, and a wind plate 32 inserted into the rotating roller 31; the conveying roller 3 is used for preliminary heating of the label paper with adhesive; a heating roller 4 is also rotatably installed between the two upright plates 11 for further heating of the label paper with adhesive; a plurality of heating plates 44 are snapped into the heating roller 4; a plurality of sets of protrusions 41 are fixedly installed in a ring array on the outer wall of the heating roller 4; and a release transfer roller 5 for removing the adhesive from the label paper is also rotatably installed between the two upright plates 11.

[0020] like Figure 3 and Figure 4 As shown, the rotating roller 31 has an annular slot 311 inside, and the rotating roller 31 has several sets of through holes 312 arranged in an annular array. The through holes 312 communicate with the slot 311. The rotating shafts at both ends of the rotating roller 31 are rotatably mounted on the upright plate 11, and a first motor 12 is fixedly installed on one side of one of the upright plates 11. The first motor 12 is fixedly connected to the rotating shaft of the rotating roller 31 and is used to drive the rotating roller 31 to rotate at a uniform speed.

[0021] like Figure 3 and Figure 4 As shown, the air plate 32 is inserted into the slot 311, and the insertion end of the air plate 32 is annular. An annular slot 321 is opened in the air plate 32. The air plate 32 has several sets of air outlets 322 arranged in an annular array. The air outlets 322 are connected to the slots 321. A column groove 323 is also opened in the inner wall of the air plate 32. The rotation shaft of the rotating roller 31 is rotatably arranged in the column groove 323, so as to keep the air plate 32 stationary inside the rotating roller 31.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, a fan 8 is fixedly installed on the outside of a vertical plate 11 on the chassis 1. A duct 81 is fixedly connected to the fan 8, and the duct 81 is fixedly connected to the air plate 32. One end of the duct 81 is connected to the empty slot 321. The fan 8 can generate hot air and continuously supply it into the empty slot 321 through the duct 81. The hot air is then blown out from the air outlet 322 and blown evenly onto the adhesive surface of the label paper passing below it through the through hole 312, thereby initially softening the adhesive. Since the hot air is blown out through the through hole 312, the outer surface of the rotating roller 31 does not contact the label paper, thus avoiding the adhesive from sticking to the surface of the rotating roller 31 during the initial heating stage. The rotation of the rotating roller 31 is driven by the first motor 12, while the internal air plate 32 remains stationary, effectively preventing the duct 81 connected to the fan 8 from twisting.

[0023] like Figure 6 and Figure 7 As shown, the heating roller 4 has a cavity 42 inside, and several partitions 43 are fixedly installed inside the cavity 42, dividing the cavity 42 into several heating zones. The heating roller 4 has a slot between two adjacent partitions 43, and the heating plate 44 is inserted into the cavity 42 along the slot. This partition design allows the operator to selectively install the heating plate 44 and independently control its temperature according to the width of the label paper and its specific position on the conveyor belt 2, so as to achieve precise heating of the colloidal target and avoid energy waste caused by heating ineffective areas. At the same time, the partitions 43 also play a good role in heat insulation, reducing mutual interference between the hot zones.

[0024] like Figure 5 , Figure 6 and Figure 7 As shown, an arc-shaped fixing plate 45 is fixedly connected to the top of the heating plate 44, and connecting plates 451 are fixedly connected to both sides of the fixing plate 45. An elastic protrusion 452 is fixedly provided on the side wall of the connecting plate 451.

[0025] like Figure 6 and Figure 7As shown, the heating roller 4 has a slot 46 on both sides of each slot, and the connecting plate 451 is inserted into the slot 46. The inner wall of the slot 46 has a limiting groove. When the heating plate 44 needs to be installed, it is aligned with the slot and inserted inward. The connecting plates 451 on both sides of the fixing plate 45 slide into the slot 46. During the insertion process, the elastic protrusion 452 is squeezed by the inner wall of the slot 46 and undergoes elastic deformation until the heating plate 44 reaches the predetermined position. The elastic protrusion 452 is exactly in contact with the limiting groove of the inner wall of the slot 46. The mounting slots are aligned and, under their own elastic force, they are snapped into the limiting slots, thus firmly fixing the heating plate 44 onto the heating roller 4. A groove 47 is provided on one side of the mounting slot 46. When disassembly is required, maintenance personnel can easily insert their fingers or tools into the groove 47 and apply outward force to pull out the fixing plate 45 together with the heating plate 44. Furthermore, the protrusions 41 on the outer wall of the heating roller 4 contact the surface of the label paper that has passed through. Through multi-point contact, the contact area between the adhesive and the entire surface of the heating roller 4 is further reduced, effectively preventing the adhesive from sticking together.

[0026] like Figure 1 and Figure 2 As shown, the release transfer roller 5 is coated with a fluorosilicone rubber coating. The adhesive on the label paper is adhered to the surface of the release transfer roller 5. A pressure roller 6 is fixedly arranged between the two vertical plates 11. A cooling plate is fixedly arranged inside the pressure roller 6. A take-up roller 7 is rotatably arranged between the two vertical plates 11 to collect the cooled adhesive. A second motor 13 is fixedly arranged on the outer wall of one of the vertical plates 11. The output shaft of the second motor 13 is fixedly connected to the rotation shaft of the take-up roller 7 to drive the take-up roller 7 to rotate for easy winding. The adhesive, which is still in a softened state and has been transferred from the surface of the release transfer roller 5, first passes around the release transfer roller 5 and then passes under the pressure roller 6. During this process, the pressure roller 6 applies pressure to the softened adhesive, and at the same time, the cooling plate inside it cools the adhesive rapidly and hardens it. Finally, the hardened adhesive is neatly wound up by the continuously rotating take-up roller 7, completing the entire waste separation process.

[0027] In practical use, the first motor 12 and the second motor 13 are turned on to drive the rotating roller 31 and the take-up roller 7 to rotate, respectively. Simultaneously, the fan 8 is started and hot air is heated. The fan 8 continuously supplies hot air to the slot 321 of the air plate 32 through the duct 81. The label paper with adhesive enters the waste discharge area along the conveyor belt 2, passing under the conveyor roller 3. Hot air is blown onto the adhesive surface of the label paper through the air outlet 322 and the through hole 312, performing non-contact preliminary heating and softening of the adhesive. The label paper continues to move forward to the area of ​​the heating roller 4. Depending on the width and position of the label strip... The heating plate 44 is used to achieve zoned temperature control, which further heats and softens the colloid. The softened colloid is adsorbed and carried away by the running release transfer roller 5. After the colloid passes around the release transfer roller 5, it passes under the pressure roller 6, and pressure is applied to the softened colloid and it is cooled and hardened to solidify and shape it. The cooled and hardened colloid is neatly wound up by the take-up roller 7. When it is necessary to replace or clean the heating plate 44, the fixing plate 45 can be manually pulled out through the groove 47 on the heating roller 4. The quick disassembly and assembly can be achieved by the snap-fit ​​structure of the elastic protrusion 452 and the limiting groove, which is convenient for maintenance.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
