Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot stamping foil technology, specifically to a hot stamping foil slitting mechanism. Background Technology
[0002] Hot stamping foil is a product used for hot stamping on plastic films and soft plastic products. It consists of a polyester film base and a transfer layer and is widely used in packaging, printing, decoration and other fields. In order to achieve the required size, hot stamping foil is cut by a slitting mechanism. During the slitting process, if the clamping force is uneven or the material is not sufficiently fixed, the hot stamping foil is prone to wrinkles due to tension imbalance, which will affect the cutting efficiency of the slitting mechanism. At the same time, the friction between the blade and the material will generate heat, causing the hot stamping foil to be locally deformed or stuck together, affecting the flatness of the cut. Therefore, a hot stamping foil slitting mechanism is proposed. Utility Model Content

[0011] Specifically, a base plate is fixedly connected between the first column and the second column on their adjacent sides. A cooling fan is installed inside the base plate.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] As one embodiment of this utility model, such as Figures 1-4 As shown, the hot stamping foil slitting mechanism of this utility model includes a first column 1, a second column 12 and a cutting cylinder 7. The cutting cylinder 7 is movably installed between the first column 1 and the second column 12. A cutting groove 20 is provided on the bottom end face of the cutting cylinder 7 for the cutting blade 21 to pass through. The top end of the cutting blade 21 is connected to the bottom end of the third slider 18. A first lead screw 17 is provided inside the cutting cylinder 7, and the third slider 18 is movably sleeved on the outside of the first lead screw 17.
[0027] The second column 12 has a second sliding groove 8 inside, and a second lead screw 10 is vertically installed inside the second sliding groove 8. A second slider 11 is movably sleeved on the outside of the second lead screw 10. One end of the cutting cylinder 7 is fixedly connected to one side of the second slider 11. A second motor 9 is fixedly installed at the top of the second column 12, and the output end of the second motor 9 is fixedly connected to one end of the second lead screw 10.
[0028] In use, the first column 1 and the second column 12 serve as a support structure to ensure that the cutting cylinder 7 moves stably between them. The cutting groove 20 opened on the bottom end face of the cutting cylinder 7 is used for the cutting blade 21 to pass through, ensuring that the cutting blade 21 can accurately cut the hot stamping foil 6. The second sliding groove 8 and the second lead screw 10 inside the second column 12 are used to drive the second slider 11 to move up and down. When the second motor 9 is started, the second lead screw 10 rotates, driving the second slider 11 to move downward, thereby pushing the cutting cylinder 7 to press the hot stamping foil 6, ensuring that the hot stamping foil 6 remains flat during the cutting process.
[0029] It should be noted that during the cutting process, the starting time of the second motor 9 is controlled to ensure that the tension of the hot stamping foil 6 is appropriate, avoiding material stretching and deformation due to excessive tension, or inaccurate cutting due to insufficient tension.
[0030] The present invention also includes a first groove 2 provided inside the first column 1, a guide rod 5 vertically installed inside the first groove 2, a first slider 4 movably sleeved on the outside of the guide rod 5, and one side of the first slider 4 being fixedly connected to the end of the cutting cylinder 7 away from the second slider 11.
[0031] In use, the first groove 2 and guide rod 5 inside the first column 1 are used to guide the first slider 4 to move up and down; the first slider 4 is fixedly connected to one end of the cutting cylinder 7 to ensure that the cutting cylinder 7 remains horizontal when pressing the hot stamping foil 6, and avoids tilting or shifting.
[0032] The present invention also includes a first motor 3 fixedly installed on the side of the first slider 4 away from the cutting cylinder 7, and the output end of the first motor 3 is fixedly connected to one end of the first lead screw 17.
[0033] When in use, after the first motor 3 is started, it drives the first lead screw 17 to rotate, thereby driving the third slider 18 to move linearly along the first lead screw 17; the third slider 18 drives the cutting blade 21 to move in the cutting groove 20, so as to achieve precise cutting of the hot stamping foil 6.
[0034] The present invention also includes a base plate 15 fixedly connected between the first column 1 and the second column 12 on their adjacent sides. A cooling fan 19 is installed inside the base plate 15. The cooling fan 19 is located directly below the cutting cylinder 7. The space between the cutting cylinder 7 and the cooling fan 19 is used for placing the hot stamping foil 6.
[0035] This utility model also includes a dustproof net 16 on the top surface of the base plate 15 and an air inlet 14 at the bottom end of the base plate 15.
[0036] When in use, after the cooling fan 19 is started, the airflow enters from the air inlet 14 of the base plate 15, is filtered by the dust filter 16 and blown to the bottom surface of the hot stamping foil 6, effectively reducing the heat generated during the cutting process and preventing the hot stamping foil 6 from deforming or sticking due to overheating.
[0037] It should be noted that the air inlet 14 provides sufficient airflow for the cooling fan 19 to ensure the cooling effect.
[0038] This utility model also includes a door 13 movably installed on one side of the cutting cylinder 7, a knife groove 22 provided at the bottom end of the third slider 18, the knife groove 22 being used for the top end of the cutting knife 21 to be installed and inserted, and the cutting knife 21 being connected to the third slider 18 by bolts 23.
[0039] During use, the door 13 is used to open and close the internal space of the cutting cylinder 7, making it convenient to replace or maintain the cutting blade 21; the blade groove 22 is used to fix the top of the cutting blade 21 and connect the cutting blade 21 to the third slider 18 by bolts 23, ensuring that the cutting blade 21 operates stably during the cutting process.
[0040] In use, the hot stamping foil 6 is first placed horizontally directly below the cutting cylinder 7. Then, the second motor 9 is started via an external power supply. The start of the second motor 9 drives the second lead screw 10 to rotate slowly. The rotation of the second lead screw 10 drives the second slider 11 to move downward in a straight line. The downward movement of the second slider 11 drives the cutting cylinder 7 and the first slider 4 to move downward, thereby allowing the cutting cylinder 7 to adhere to the surface of the hot stamping foil 6 and press the hot stamping foil 6 downward. The hot stamping foil 6 is evenly flattened, ensuring uniform tension distribution and avoiding uneven cutting. If wrinkles or misalignments occur, the first motor 3 and the cooling fan 19 are activated simultaneously. The first motor 3 drives the first lead screw 17 to rotate, thereby driving the third slider 18 to move linearly. This allows the cutting blade 21 to move at the cutting groove 20, enabling the cutting blade 21 to cut the hot stamping foil 6 attached to the bottom surface of the cutting cylinder 7. The activation of the cooling fan 19 blows airflow toward the bottom surface of the hot stamping foil 6, effectively reducing the heat generated by friction during the cutting process and preventing the hot stamping foil 6 from deforming or sticking due to overheating.
