Description

Technical Field

[0001] This utility model relates to the field of paper processing technology, and more specifically, to a cutting device for thermal sublimation transfer paper. Background Technology

[0002] Sublimation transfer paper is a special type of paper specifically designed for heat transfer printing. It is mainly used for printing patterns on personalized clothing, accessories, gifts, signs, home decorations, and other products. The production principle is to pre-print ink with sublimation properties onto the transfer paper according to the designed pattern, and then place the printed paper into the substrate. Under certain temperature and pressure, heat transfer is carried out. The ink sublimates under high temperature, penetrates into the substrate, and solidifies after cooling, forming a brightly colored pattern.

[0003] Currently, when using sublimation transfer paper, it needs to be cut to the required size according to the size of the substrate using a cutting device. However, most existing cutting devices directly cut the sublimation transfer paper with blades. During the cutting process, the stability of the paper cannot be maintained, and the paper is prone to shifting, which affects the cutting accuracy. Moreover, during the storage process before cutting, the sublimation transfer paper is easily affected by environmental temperature and humidity, curling, stacking, and other factors, which can cause problems such as wrinkles and curling edges. Direct cutting cannot guarantee the cutting effect. Therefore, this utility model proposes a cutting device for sublimation transfer paper. Utility Model Content

This device solves the problem that existing cutting devices use blades to directly cut sublimation transfer paper, which cannot maintain the stability of the paper during the cutting process, causing the paper to easily shift and affecting cutting accuracy. Furthermore, during the storage process before cutting, sublimation transfer paper is easily affected by environmental temperature and humidity, curling, stacking, and other factors, leading to problems such as wrinkles and curling edges. Direct cutting cannot guarantee the cutting effect.

[0008] A cutting device for thermal sublimation transfer paper includes a base plate, a support frame fixedly connected to the top of the base plate, a cylinder fixedly connected to the top of the support frame, and the output end of the cylinder extending movably through the inner side of the support frame. A lifting plate is fixedly connected to the output end of the cylinder. Two linkage assemblies are movably hinged to the bottom of the lifting plate via hinge pins. A tension spring assembly is fixedly connected between the two linkage assemblies. Two sliding sleeves are slidably connected to the support frame, and two sliding rods are fixedly connected between the two sliding sleeves. Two flattening frames are slidably connected to the circumferential surfaces of the two sliding rods, and the bottom ends of the two linkage assemblies are respectively movably hinged to the two flattening frames via hinge pins.

[0013] 3. Beneficial effects

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) In this scheme, when the thermal sublimation transfer paper is cut, the cylinder controls the cutting blade to move down to cut the paper through the lifting plate.

The two paper pressure rollers press the paper and unfold it outward. When unfolding, the paper is rolled and smoothed so that the paper cutting position is flat before cutting, thereby improving the stability of paper cutting and ensuring cutting accuracy and cutting effect.

[0025] Example:

[0026] Please see Figure 1-4A cutting device for thermal sublimation transfer paper includes a base plate 1, a support frame 2 fixedly connected to the top of the base plate 1, a cylinder 3 fixedly connected to the top of the support frame 2, and the output end of the cylinder 3 extending movably through the inner side of the support frame 2. A lifting plate 4 is fixedly connected to the output end of the cylinder 3. Two connecting rod assemblies 5 are movably hinged to the bottom of the lifting plate 4 via hinge shafts. A tension spring assembly 6 is fixedly connected between the two connecting rod assemblies 5. Two sliding sleeves 7 are slidably connected to the support frame 2. Two sliding rods 8 are fixedly connected between the two sliding sleeves 7. Two flattening frames 9 are slidably connected to the circumferential surfaces of the two sliding rods 8. The bottom ends of the two connecting rod assemblies 5 are movably hinged to the two flattening frames 9 via hinge shafts. A paper pressure roller assembly 10 is rotatably connected inside each of the two flattening frames 9. A cutting blade 11 is fixedly connected to the bottom of the lifting plate 4 and is located inside the two connecting rod assemblies 5. A cutting opening 12 is provided on the base plate 1, and the cutting opening 12 matches the cutting blade 11.

[0027] In this embodiment, when cutting the sublimation transfer paper, the sublimation transfer paper is conveyed above the base plate 1, so that the cutting position corresponds to the cutting blade 11 and the cutting opening 12. The cylinder 3 controls the lifting plate 4 to press down, and the lifting plate 4 drives the cutting blade 11 to move downward to cut the paper. During the downward movement of the cutting blade 11, the lifting plate 4 drives the two connecting rod assemblies 5 to move down. The two connecting rod assemblies 5 cause the two flattening frames 9 to move downward smoothly through the two sliding rods 8 and the two sliding sleeves 7. The bottom of the two paper pressure roller groups 10 first contacts the paper. The lifting plate 4 continues to press down, causing the two flattening frames 9 to unfold through the two connecting rod assemblies 5. The two flattening frames 9 move smoothly on the two sliding rods 8. The paper slides to both sides, causing the two pressure rollers 10 to roll and smooth the paper surface, ensuring the flatness of the cutting position. Then, the cutting blade 11 passes through the two pushers 9 and enters the cutting opening 12 to complete the cutting of the paper. When the two pushers 9 are away, the two linkage assemblies 5 pull the tension spring assembly 6 to extend. After the paper is cut, the cylinder 3 controls the lifting plate 4 and the cutting blade 11 to rise and reset. Under the tension of the tension spring assembly 6, the two linkage assemblies 5 reset the two pushers 9 and the two pressure rollers 10. The two sliding sleeves 7 and the two sliding rods 8 follow the two pushers 9 to rise and reset, facilitating the subsequent cutting of the paper.

[0028] Specifically, a guide plate assembly 13 is fixedly connected to one side of the base plate 1, and the guide plate assembly 13 corresponds to the cutting opening 12.

[0029] In this embodiment, the guide plate assembly 13 is located at one end of the base plate 1, which enables the sublimation transfer paper to be guided upwards onto the base plate 1, facilitating paper transport.

[0030] Specifically, an auxiliary rod assembly 14 is fixedly connected to the top of the lifting plate 4, and the auxiliary rod assembly 14 moves through the support frame 2.

[0031] In this embodiment, the auxiliary rod assembly 14 passes through the support frame 2 to assist in the lifting and lowering of the lifting plate 4, so that the movement of the lifting plate 4 remains stable.

[0032] Specifically, a sharpening blade assembly 15 is fixedly connected inside the cutting opening 12, and the sharpening blade assembly 15 corresponds to the cutting blade 11.

[0033] In this embodiment, when the cutting blade 11 cuts the thermal sublimation transfer paper, it enters the cutting opening 12. The sharpening blade assembly 15 inside the cutting opening 12 sharpens the cutting blade 11, keeping it sharp and ensuring the cutting effect.

[0034] Specifically, a discharge plate 16 is fixedly connected to the end of the base plate 1 away from the guide plate assembly 13, and the discharge plate 16 corresponds to the cutting opening 12.

[0035] In this embodiment, the cut sublimation transfer paper will slide out from the output plate 16, which facilitates the output of the cut sublimation transfer paper.

[0036] Working principle: The sublimation transfer paper is fed above the base plate 1 through the cutting blade 11 and the cutting opening 12. When the cutting position of the paper corresponds to the cutting blade 11 and the cutting opening 12, the cylinder 3 controls the lifting plate 4 to press down. The lifting plate 4 drives the cutting blade 11 and the two connecting rod assemblies 5 to press down. Under the tension of the tension spring assembly 6, the two connecting rod assemblies 5 drive the two flattening frames 9 to move down. The two flattening frames 9 drive the two sliding sleeves 7 to slide on the support frame 2 through the two sliding rods 8. The two sliding sleeves 7 and the two sliding rods 8 keep the downward movement of the two flattening frames 9 stable. The bottom of 9 always corresponds to the sublimation transfer paper. During the downward movement of the flattening frame 9, the pressure roller group 10 will come into contact with the paper surface. At this time, the cylinder 3 controls the lifting plate 4 to continue to press down. The two connecting rod assemblies 5 gradually unfold and pull the tension spring assembly 6. The two pressure roller groups 10 in the two flattening frames 9 unfold to both sides respectively. The two flattening frames 9 slide on the surface of the two slide rods 8, so that the unfolding of the two pressure roller groups 10 is stable and the paper is flattened. The cutting blade 11 follows the downward movement of the lifting plate 4, passes through the two flattening frames 9 and enters the cutting hole 12 to complete the cutting of the sublimation transfer paper.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
