Description

Technical Field

[0001] The invention relates to the technical field of die-cutting machinery, in particular to a multifunctional slitting device integrating edge scraping and drying. Background Art

[0002] The raw materials of the die-cutting industry, such as single-sided tape and double-sided tape, are supplied in the form of rolls, that is, the materials are wound on a long round roll core (usually a plastic roll core), with a length of about 0.5-1.2m. When making die-cut products, the raw materials need to be cut into the required specifications and then sent to the workshop for production. When the required specifications are cut, they need to be cut with a slitting knife. When slitting, it is also necessary to spray water at the lower cutting knife position to prevent the waste residue on the material from sticking to the slitting knife and causing damage to the slitting knife. When the slitting knife is damaged or not sharp, it will affect the smoothness of the cut material. There will be burrs or residual glue at the lower cutting position of the edge of the cut material. This leads to the problem of product dirtiness due to burrs when the subsequent production line is used. Glue materials, especially double-sided adhesives without substrates, will cause glue pulling on the edges during production and use, resulting in the product being scrapped due to lack of glue.

[0003] Therefore, there is an urgent need for a method that can solve the problems of burrs or residual glue at the cutting position of the material to be cut after die-cutting, thereby affecting the normal operation of the subsequent production line and the integrity of the product. Summary of the invention

[0004] The purpose of the present invention is to provide a multifunctional slitting device integrating edge scraping and drying in order to solve the defects of the prior art that the die-cut products may have burrs or residual glue at the cutting position after die-cutting.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] The technical solution of the present invention is to provide a multifunctional slitting device integrating scraping and drying, including a rotating shaft mechanism for transporting raw materials, a slitting knife arranged in sequence on one side of the rotating shaft mechanism and used for die-cutting the raw materials, a water spray pipe for cleaning the slitting knife, a scraping mechanism for removing residual materials at the edge of the cut part of the raw material, an air inflation mechanism arranged on the rear side of the scraping mechanism and connected to the rotating shaft mechanism, and a heating mechanism arranged at the end of the rotating shaft mechanism.

[0007] In some specific embodiments, the rotating shaft mechanism includes a machine tool and a rotating shaft disposed on the machine tool and loaded with the raw material, and the machine tool is used to provide power for the rotating shaft to transport the raw material.

[0008] In some specific embodiments, the slitting knife moves vertically in a direction approaching and / or away from the rotating shaft.

[0009] In some specific embodiments, the water spray port of the water spray pipe is aligned with the slitting knife and is perpendicular to the rotating shaft.

[0010] In some specific embodiments, the scraping mechanism includes a grinding wheel and a mechanical arm that drives the grinding wheel to move along the rotating shaft.

[0011] In some specific embodiments, the mechanical arm drives the grinding wheel to move horizontally along the rotating shaft.

[0012] In some specific embodiments, the robot arm also drives the grinding wheel to move closer to and / or away from the rotating shaft.

[0013] In some specific embodiments, the air inflation mechanism includes an air inflation shaft disposed between the two sections of the rotating shaft and connected to the rotating shafts at both ends at the head and tail, respectively, and an air source component for inflating the air inflation shaft.

[0014] In some specific embodiments, the outer diameter of the inflatable shaft when not inflated is consistent with the outer diameter of the rotating shaft, and the outer diameter of the inflatable shaft when inflated is larger than the inner diameter of the knife-cut portion of the raw material;

[0015] When the cut part of the raw material is transported to the air shaft, the air shaft is inflated to prevent the cut part of the raw material from continuing to move, so that the grinding wheel removes the residual material on the cut part of the raw material; when the grinding wheel operation is completed, the air shaft is deflated to allow the cut part of the raw material to continue to move.

[0016] In some specific embodiments, the heating mechanism includes a baking oven, and when the knife-cut portion of the raw material moves into the baking oven, the baking oven is used to dry the moisture on the knife-cut portion of the raw material.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The device of the present invention processes the cut part of the raw material through a scraping mechanism and a heating mechanism so that the edge of the cut part of the raw material will not have debris and becomes smooth. When it enters the production line for subsequent operation, the problem of dirt on the edge of the cut part of the raw material falling onto the product is effectively reduced, and the problem of glue pulling caused by residual glue on the edge of the cut part of the raw material is avoided. While greatly improving the product quality, the production efficiency is also improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0024] In the following embodiments, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0025] Embodiment 1:

[0026] like Figures 1-2 As shown, a multifunctional slitting device integrating scraping and drying is shown, which includes a rotating shaft mechanism 1 for transporting raw materials 7, a slitting knife 2 which is arranged on one side of the rotating shaft mechanism 1 and is used for die-cutting the raw materials 7, a water spray pipe 3 for cleaning the slitting knife 2, a scraping mechanism 4 for removing residual substances at the edge of the raw material cut portion 8, an air inflation mechanism 5 which is arranged at the rear side of the scraping mechanism 4 and connected to the rotating shaft mechanism 1, and a heating mechanism 6 which is arranged at the end of the rotating shaft mechanism 1. The technical solution is that the raw material 7 is transported to the slitting knife 2 on the rotating shaft mechanism 1 to be cut by the slitting knife 2 and the slitting knife 2 is washed by water sprayed by the water spray pipe 3. The raw material 7 after slitting is the raw material cut portion 8. When the raw material cut portion 8 is further transported to the air inflation mechanism 5, the air inflation mechanism 5 is inflated to block the raw material cut portion 8 from continuing to be transported forward. At this time, the scraping mechanism 4 removes residual substances at the edge of the raw material cut portion 8, such as burrs, residual glue, etc. When the scraping mechanism 4 completes the operation, the air inflation mechanism 5 deflates the raw material cut part 8 to continue to be transported to the heating mechanism 6, which heats and dries the moisture remaining on the raw material cut part 8. After completing the entire process, the raw material cut part 8 can be used in the subsequent production line.

[0027] In this embodiment, the rotating shaft mechanism 1 includes a machine tool 1-1 and a rotating shaft 1-2 arranged on the machine tool 1-1 and loaded with raw materials 7. The machine tool 1-1 is used to provide power for the rotating shaft 1-1 to transport the raw materials 7, so that the transportation operation is automated and the operation efficiency is improved.

[0028] In this embodiment, the slitting knife 2 moves vertically in a direction approaching and / or away from the rotating shaft 1-2, so that when the raw material 7 is transported to the slitting knife 2, the slitting knife 2 vertically approaches the rotating shaft 1-2 to cut the raw material 7. After completing the slitting operation, the slitting knife 2 vertically moves away from the rotating shaft 1-2.

[0029] In this embodiment, the water outlet of the water spray pipe 3 is aimed at the slitting knife 2 perpendicular to the rotating shaft 1-2, so that when the slitting knife 2 is slitting, the water spraying force of the water spray pipe 3 can wash away the waste residue remaining on the slitting knife 2, thereby preventing the slitting knife 2 from being damaged and becoming blunt due to the residual waste residue.

[0030] In this embodiment, the scraping mechanism 4 includes a grinding wheel 4-1 and a mechanical arm 4-2 that drives the grinding wheel 4-1 to move along the rotating shaft 1-2. When the raw material cutting portion 8 needs to remove residual materials at its edge, the mechanical arm 4-2 drives the grinding wheel 4-1 to move to the raw material cutting portion 8 to perform the operation. When the raw material cutting portion 8 does not need to remove residual materials at its edge or the grinding wheel 4-1 completes its scraping operation, the mechanical arm 4-2 drives the grinding wheel 4-1 away from the raw material cutting portion 8 to avoid affecting the transportation of the raw material cutting portion 8.

[0031] In this embodiment, the robot arm 4-2 drives the grinding wheel 4-1 to move horizontally along the rotating shaft 1-2, and also drives the grinding wheel 4-1 to approach and / or move away from the rotating shaft 1-2.

[0032] In this embodiment, the air expansion mechanism 5 includes an air expansion shaft arranged between the two sections of the rotating shaft 1-2 and connected to the two end rotating shafts 1-2 at the head and tail respectively, and an air source component such as an air pump for inflating the air expansion shaft; when the raw material cutting part 8 is transported to the air expansion shaft, the air expansion shaft is inflated to prevent the raw material cutting part 8 from continuing to move, so that the grinding wheel 4-1 removes the residual material on the raw material cutting part 8; when the grinding wheel 4-1 completes the operation, the air expansion shaft is deflated to allow the raw material cutting part 8 to continue to move.

[0033] In this embodiment, the heating mechanism 6 includes a baking oven. When the knife-cut portion 8 of the raw material moves into the baking oven, the baking oven is used to dry the moisture of the knife-cut portion 8 of the raw material.

[0034] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
