Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-adhesive die-cutting technology, and in particular to a self-adhesive die-cutting device for printing paper that facilitates tool replacement. Background Technology
[0002] Self-adhesive fabric has a wide range of uses, including as decorative patches for clothing and for securing sofas, tablecloths, and more. In the production and processing of self-adhesive fabric, different sizes are produced depending on the product type. This requires processing on a device equipped with die-cutting blades. However, in actual use, we have found that the blades on traditional die-cutting devices are fixed to a blade plate, for example, by adhesive. This makes it difficult to quickly remove and replace damaged blades. Forcibly removing them can damage both the blade plate and the blade itself. Damaged blades and blade plates necessitate the manufacture of new ones, increasing costs and reducing the production efficiency of self-adhesive fabric.
[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention
[0004] This invention proposes a self-adhesive die-cutting device for printing paper with convenient blade replacement, which solves the above-mentioned problems existing in the use of the prior art.
[0005] The technical solution of this utility model is implemented as follows: A self-adhesive die-cutting device for printing paper with convenient blade replacement includes a machine housing. An upper die-cutting plate and a lower die-cutting plate are arranged inside the machine housing. A slot 1 is opened at the bottom of the upper die-cutting plate. A die-cutting blade is arranged below the upper die-cutting plate. The top of the die-cutting blade is inserted into the slot 1. Four locking strips are fixedly connected to both sides of the die-cutting blade. A slot 2 adapted to the die-cutting blade is opened on both sides of the bottom of the upper die-cutting plate. Eight movable cavities are opened on both sides of the upper die-cutting plate. A locking plate is slidably installed inside the movable cavity. Every two locking plates are distributed on both sides of a corresponding locking strip.
[0006] The self-adhesive die-cutting device for printing paper described above for easy replacement of cutting tools further includes: a plurality of grooves on the top of the card plate, a spring fixedly connected inside the groove, and the end of the spring away from the groove fixedly connected to the inner wall of the movable cavity.
[0007] The self-adhesive die-cutting device for printing paper described above for convenient blade replacement further includes: a mounting frame fixedly installed on the bottom of the lower die-cutting plate, and multiple sliding sleeves fixedly connected to both sides of the bottom of the mounting frame.
[0008] The self-adhesive die-cutting device for printing paper described above for convenient tool replacement further includes: two slide rails fixedly installed inside the machine housing, and multiple sliding sleeves slidably installed on the corresponding slide rails.
[0009] The self-adhesive die-cutting device for printing paper described above for easy tool replacement further includes: a connecting plate fixedly installed on one side of the bottom of the mounting frame; a threaded screw installed on the internal thread of the connecting plate; a stepper motor fixedly installed at the end of the threaded screw away from the connecting plate; and the stepper motor fixedly installed inside the machine housing.
[0010] The self-adhesive die-cutting device for printing paper described above for convenient blade replacement further comprises: a fixed frame fixedly installed inside the machine housing; a movable plate slidably installed on the surface of the fixed frame; an upper die-cutting plate fixedly installed at the bottom of the movable plate; and an electric push rod fixedly installed at the top of the machine housing. The output end of the electric push rod extends through to the inner side of the fixed frame and is fixedly connected to the movable plate.
[0011] The self-adhesive die-cutting device for printing paper described above for convenient blade replacement further includes: four buffer springs sleeved on the surface of the fixed frame, the bottom ends of the buffer springs being fixedly mounted on the fixed frame, and the top ends of the buffer springs being adapted to the movable plate.
[0012] In summary, the beneficial effects of this utility model are as follows: 1. This utility model adopts a structural design that allows for quick disassembly and assembly of the die-cutting tool without damaging it. According to actual usage needs, the die-cutting tool can be quickly removed from the upper die-cutting plate for replacement without damaging the tool, and then quickly installed back onto the upper die-cutting plate. This reduces cost investment while ensuring the progress and efficiency of self-adhesive production, and provides assistance and convenience for users' work.
[0013] 2. This utility model utilizes a groove and a spring. The spring is installed and fixed within the groove, with one end also fixed to the inner wall of the movable cavity. When the clamping plate is moved upward, it compresses the groove. Once the die-cutting tool is in place, the user releases the clamping plate, which then pops out of the movable cavity under the action of the spring. This secures the clamping strip and the die-cutting tool in their current positions, ensuring the stability and firmness of the die-cutting tool after installation. This improves the precision and quality of self-adhesive die-cutting processing and provides convenience for the user's work.
[0014] 3. This utility model, through the arrangement of a mounting frame, slide rail, connecting plate, stepper motor, and threaded screw, ensures that both the mounting frame and the lower die-cutting plate are located outside the machine during operation. Therefore, during operation, the self-adhesive material is first placed on the lower die-cutting plate on the mounting frame. Then, the stepper motor is started to drive the threaded screw to rotate. Because the connecting plate and the threaded screw are threadedly connected, the connecting plate moves into the machine housing. Simultaneously, the connecting plate drives the mounting frame to move into the machine housing, and the mounting frame drives multiple sliding sleeves to slide on their corresponding slide rails. This continues until the mounting frame and the lower die-cutting plate move into the machine housing, with the lower die-cutting plate directly below the upper die-cutting plate. Then, an electric push rod drives the upper and lower die-cutting plates to close for die-cutting processing. This ensures the normal operation of the die-cutting machine and prevents users from accidentally putting their hands inside the machine housing during feeding, thus improving the safety of self-adhesive die-cutting and providing convenience for users.
[0015] 4. This utility model, through the setting of a fixed frame, a movable plate and an electric push rod, when the electric push rod is activated during operation, the electric push rod will push the movable plate to slide down on the fixed frame, and at the same time the upper die-cutting plate will also move down with the movable plate to close with the lower die-cutting plate to complete the self-adhesive die-cutting process.
[0016] 5. This utility model incorporates a buffer spring, which acts as a buffer for the moving plate. When the moving plate is pressed down, and after the upper and lower die-cutting plates are closed, the moving plate compresses the buffer spring. Simultaneously, the buffer spring generates a reaction force on the moving plate, thus achieving the purpose of buffering. This prevents the upper and lower die-cutting plates from being damaged due to excessive mutual compression during mold closing, extends the service life of the upper and lower die-cutting plates, and provides convenience for users' work.

[0020] The following will refer to the appendix in the embodiments of this utility model. Figure 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example
[0021] A self-adhesive die-cutting device for printing paper with easy-to-change blades includes a machine housing 1. Inside the machine housing 1, there is an upper die-cutting plate 2 and a lower die-cutting plate 3. The bottom of the upper die-cutting plate 2 has a slot 4. A die-cutting blade 5 is arranged below the upper die-cutting plate 2. The top of the die-cutting blade 5 is inserted into the slot 4. Four retaining strips 6 are fixedly connected to both sides of the die-cutting blade 5. The bottom of the upper die-cutting plate 2 has slots 7 that are adapted to the die-cutting blade 5. Eight movable cavities 8 are opened on both sides of the upper die-cutting plate 2. A retaining plate 9 is slidably installed inside the movable cavity 8. Every two retaining plates 9 are distributed on both sides of a corresponding retaining strip 6.
[0022] The specific usage process is as follows: When the die-cutting cutter 5 or the upper die-cutting plate 2 is damaged and needs to be replaced, the user moves the clamping plate 9 upwards. Simultaneously, the clamping plate 9 slides within the movable cavity 8. In this way, the movable cavity 8 can limit and guide the clamping plate 9, ensuring that it can move vertically up and down, providing convenience for the user. At the same time, as the clamping plate 9 moves upwards, it also compresses the spring 11, which is then compressed into the groove 10 until the clamping plate 9 is completely moved into the movable cavity 8. Then, the die-cutting cutter 5 is slid to one side to remove it from the upper die-cutting plate 2. The protruding part at the top of the die-cutting cutter 5 will move out of the first clamping groove 4, and simultaneously, the left and right parts of the die-cutting cutter 5 will also move out of the corresponding second clamping groove 7. This completes the process. To quickly remove the die-cutting cutter 5 and replace it with a new one, align the protruding part on top of the die-cutting cutter 5 with the slot 1 4 and align the two sides of the die-cutting cutter 5 with the slot 2 7. Then, insert the die-cutting cutter 5. At the same time, the retaining strips 6 will move along with the die-cutting cutter 5. Before this, all the retaining plates 9 must be pushed upwards so that the bottom of the retaining plates 9 is fully inserted into the movable cavity 8. Only then can the die-cutting cutter 5 be pushed to fully engage with the upper die-cutting plate 2. When the die-cutting cutter 5 is fully engaged in the slot 1 4, each retaining strip 6 is also positioned between the two retaining plates 9. At this time, under the action of the spring 11, the retaining plates 9 will be ejected into the corresponding movable cavity 8, and the two retaining plates 9 will be engaged with the corresponding retaining strips 6. The two sides of the upper die-cutting plate 2 are designed to lock the corresponding clips 6 in place, preventing the die-cutting blade 5 from moving freely during operation and ensuring its stability. This improves the quality and precision of self-adhesive die-cutting, providing convenience for users. This disassembly and assembly method prevents both the die-cutting blade 5 and the upper die-cutting plate 2 from being damaged simultaneously, allowing users to replace only one of them. The disassembly and assembly are also extremely fast and efficient, increasing the speed and efficiency of blade replacement and providing convenience for users. The die-cutting blade 5 is secured to the upper die-cutting plate 2 from one side. After replacing either the die-cutting blade 5 or the upper die-cutting plate 2, the machine can be started. When starting the machine, the safety precautions are taken. An electric push rod 21 mounted on the top of the machine housing 1 pushes a movable plate 19 to slide on a fixed frame 18. Simultaneously, the upper die-cutting plate 2, mounted below the movable plate 19, moves along with it. Finally, the upper die-cutting plate 2, along with the die-cutting tool 5, closes with the lower die-cutting plate 3, thus die-cutting the self-adhesive material on the lower die-cutting plate 3. It should be noted that multiple rectangular grooves matching the die-cutting tool 5 are provided on the upper surface of the lower die-cutting plate 3, enabling the self-adhesive material to be die-cut into the corresponding shape. Furthermore, the lower die-cutting plate 3 can be removed and replaced from the mounting frame 12, and the die-cutting tool 5 can also be removed and replaced from the upper die-cutting plate 2. This allows for the die-cutting of self-adhesive materials that meet actual processing requirements, providing convenience for users.Therefore, a structural design that allows for quick disassembly and assembly of the die-cutting tool without damaging it is adopted. Based on actual usage needs, the die-cutting tool 5 can be quickly removed from the upper die-cutting plate 2 for replacement without damage, and then quickly installed back onto the upper die-cutting plate 2. This ensures self-adhesive production progress and efficiency while reducing costs, providing assistance and convenience for users.
[0023] The top of the card plate 9 has multiple grooves 10, and a spring 11 is fixedly connected inside the groove 10. The end of the spring 11 away from the groove 10 is fixedly connected to the inner wall of the movable cavity 8.
[0024] Specifically, regarding the arrangement of the groove 10 and the spring 11, the spring 11 is installed and fixed within the groove 10, and one end of the spring 11 is also fixed to the inner wall of the movable cavity 8. Thus, when the clamping plate 9 is moved upward, it will compress the groove 10. After the die-cutting cutter 5 is installed in place, the user releases the clamping plate 9, and the clamping plate 9 will pop out of the inner cavity of the movable cavity 8 under the action of the spring 11, thereby locking the clamping strip 6 and the die-cutting cutter 5 in the current position, ensuring the stability and firmness of the die-cutting cutter 5 after installation, improving the accuracy and quality of self-adhesive die-cutting processing, and providing convenience for the user's work.
[0025] A mounting bracket 12 is fixedly installed on the bottom of the lower die-cutting plate 3. Multiple sliding sleeves 13 are fixedly connected to both sides of the bottom of the mounting bracket 12. Two slide rails 14 are fixedly installed inside the machine housing 1. The multiple sliding sleeves 13 are slidably installed on the corresponding slide rails 14. A connecting plate 15 is fixedly installed on one side of the bottom of the mounting bracket 12. A threaded screw 17 is threaded inside the connecting plate 15. A stepper motor 16 is fixedly installed at the end of the threaded screw 17 away from the connecting plate 15. The stepper motor 16 is fixedly installed inside the machine housing 1.
[0026] Specifically, regarding the mounting bracket 12, slide rail 14, connecting plate 15, stepper motor 16, and threaded screw 17, during operation, the mounting bracket 12 is located outside the machine, and similarly, the lower die-cutting plate 3 is also located outside the machine. Therefore, during operation, the self-adhesive is first placed on the lower die-cutting plate 3 on the mounting bracket 12, and then the stepper motor 16 is started to drive the threaded screw 17 to rotate. Because the connecting plate 15 and the threaded screw 17 are threadedly connected, the connecting plate 15 will move into the machine housing 1. At the same time, the connecting plate 15 will drive the mounting bracket 12 towards the machine. The machine moves inside the outer casing 1, and the mounting bracket 12 drives multiple sliding sleeves 13 to slide on the corresponding slide rails 14. This continues until the mounting bracket 12 and the lower die-cutting plate 3 move into the machine casing 1, with the lower die-cutting plate 3 located directly below the upper die-cutting plate 2. Then, the electric push rod 21 drives the upper die-cutting plate 2 and the lower die-cutting plate 3 to close the mold for die-cutting processing. This ensures the normal operation of the die-cutting machine and prevents users from putting their hands into the machine casing 1 when feeding materials, thus improving the safety of self-adhesive die-cutting processing and providing convenience for users.
[0027] A fixed frame 18 is fixedly installed inside the machine housing 1. A movable plate 19 is slidably installed on the surface of the fixed frame 18. The upper die-cutting plate 2 is fixedly installed at the bottom of the movable plate 19. An electric push rod 21 is fixedly installed on the top of the machine housing 1. The output end of the electric push rod 21 passes through the inner side of the fixed frame 18 and is fixedly connected to the movable plate 19.
[0028] Specifically, the fixed frame 18, the movable plate 19 and the electric push rod 21 are set up so that when the electric push rod 21 is activated during operation, the electric push rod 21 will push the movable plate 19 to slide down on the fixed frame 18. At the same time, the upper die-cutting plate 2 will also move down with the movable plate 19 and close with the lower die-cutting plate 3 to complete the self-adhesive die-cutting process.
[0029] Four buffer springs 20 are sleeved on the surface of the fixed frame 18. The bottom end of the buffer spring 20 is fixedly installed on the fixed frame 18, and the top end of the buffer spring 20 is adapted to the movable plate 19.
[0030] Specifically, the buffer spring 20 is designed to cushion the moving plate 19. When the moving plate 19 is pressed down, and after the upper die-cutting plate 2 and the lower die-cutting plate 3 are closed, the moving plate 19 will compress the buffer spring 20. At the same time, the buffer spring 20 will also generate a reaction force on the moving plate 19, thereby achieving the purpose of cushioning. This prevents the upper die-cutting plate 2 and the lower die-cutting plate 3 from being damaged due to excessive mutual compression during mold closing, extends the service life of the upper die-cutting plate 2 and the lower die-cutting plate 3, and provides convenience for users' work.
[0031] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
