Description

Technical Field

[0001] This utility model belongs to the field of self-adhesive film production and processing technology, and in particular relates to a die-cutting device for self-adhesive films. Background Technology

[0002] Self-adhesive rolls are the basic form of self-adhesive products. They refer to continuous rolls made of face stock, adhesive, and backing paper. They are mainly used for die-cutting and printing to produce finished products such as labels and stickers, and are suitable for efficient processing on automated production lines.

[0003] Existing technology (publication number: CN223480439U) discloses a self-adhesive paper die-cutting device, including a working plate, a carrier frame, and a self-adhesive paper roller. A tensioning mechanism for tightening the self-adhesive paper is provided on one side of the carrier frame. A slitting mechanism for cutting the self-adhesive paper is provided on the working plate. A feeding mechanism for feeding the self-adhesive paper is provided on one side of the slitting mechanism. A feeding mechanism for automatically unloading the cut self-adhesive paper is provided on the top of the working plate and on one side of the slitting mechanism. In this invention, the self-adhesive paper roller on the carrier frame can rotate for feeding. The tensioning mechanism prevents loosening during feeding, while the feeding mechanism moves the self-adhesive paper below the slitting mechanism for cutting. Furthermore, it prevents the self-adhesive paper from sticking to the slitting mechanism during operation. After cutting, the self-adhesive paper is automatically unloaded by the feeding mechanism.

[0004] The aforementioned patent has the following problems: This patent has some drawbacks in its use, such as: when the self-adhesive roll is die-cut by the slitting mechanism, the other side of the self-adhesive paper will be located on the feeding mechanism. However, the self-adhesive paper located on the feeding mechanism does not have any structure for fixing. This causes the self-adhesive paper located on the feeding mechanism to move easily when the slitting structure is die-cutting the self-adhesive paper, affecting the accuracy of the die-cutting.

[0005] In view of this, we propose a die-cutting device for self-adhesive labels. Utility Model Content

[0006] The purpose of this invention is to provide a die-cutting device for self-adhesive labels to solve the problems mentioned in the background art.

[0007] In view of this, the present invention provides a die-cutting device for self-adhesive labels, including a die-cutting machine body, an electric slide rail, an electric slider, and an electric cylinder provided above the die-cutting machine body, and a cutter provided at the output end of the electric cylinder, and further including: The blade holder is fixedly installed on the top of the die-cutting machine body, and the electric slide rail, electric slider and electric cylinder are all located inside the blade holder. Two rotating frames are provided below the cutter, and a pressure rod, a conveying roller and several flattening rollers are provided between the two rotating frames. Two unwinding frames are arranged on the top of the die-cutting machine body, and a connecting plate is rotatably installed on one side of each of the two unwinding frames, and a pressure roller is rotatably installed between the two connecting plates; A power assembly is located on the die-cutting machine body and is used to drive the rotating frame to rotate in both directions and to drive the conveyor rollers to rotate.

[0008] In this technical solution, the operator inserts both ends of the self-adhesive film roll between two unwinding frames. Then, one end of the self-adhesive film roll is passed under the pressure roller, flattening roller, and conveyor roller. The first motor is then turned on, and its output drives the rotating frame to rotate towards the flattening roller. The rotating frame, in turn, drives the second motor, the conveyor roller pressure bar, and several flattening rollers to rotate until one side of the rotating frame is engaged in a rectangular groove. Simultaneously, the flattening roller and conveyor roller press the self-adhesive film onto the die-cutting machine body. At this point, the operator turns on the second motor, which drives the conveyor roller to rotate. Under the action of friction, the rotating conveyor roller squeezes the self-adhesive film and moves it under the slitting roller. Finally, the operator turns on the... The electric slide rail, electric cylinder, and first motor are activated. When the electric slide rail is opened by personnel, the electric slider and electric cylinder move back and forth along the bottom of the electric slide rail, thereby driving the first mounting frame, cutting roller, and pressure roller to die-cut the self-adhesive paper unfolded below. When the output end of the electric cylinder extends downward, it drives the first mounting frame, cutting roller, and pressure roller to move towards the self-adhesive paper below. This allows the cutting roller to die-cut the self-adhesive paper below as it moves left and right. The output end of the first motor drives the rotating frame to rotate in the opposite direction until the bottom of the pressure rod presses down on the self-adhesive paper being die-cut, ensuring that the self-adhesive paper being die-cut does not move as the cutting roller moves left and right.

[0009] In the above technical solution, the power component further includes: The first motor is fixedly mounted on one side of the tool holder and located below the electric cylinder. The output end of the first motor passes through one side of the tool holder and is fixedly connected to one of the rotating frames. The output end of the first motor is rotatably connected to the tool holder. The second motor is fixedly installed on one side of one of the rotating frames. The output end of the second motor passes through one side of one of the rotating frames and is coaxially connected to the conveyor roller. The output end of the second motor is rotatably connected to one of the rotating frames.

[0010] In this technical solution, the output end of the first motor can rotate in both the forward and reverse directions, thereby stably controlling the rotating frame to reciprocate on the die-cutting machine body, which in turn drives the rolling roller and pressure rod to roll out and fix the self-adhesive paper on the die-cutting machine body.

[0011] In the above technical solution, further, a plurality of the rolling rollers are arranged at equal intervals, and the two ends of the rolling rollers are rotatably connected to two rotating frames respectively. The conveying roller is located between the plurality of rolling rollers and the blade holder, and one end of the conveying roller is rotatably connected to one of the rotating frames.

[0012] In this technical solution, when the flattening roller presses the self-adhesive paper onto the die-cutting machine body, it can flatten the wrinkles on the self-adhesive paper, thus preventing the wrinkles on the self-adhesive paper from affecting the die-cutting effect.

[0013] In the above technical solution, the rotating frame has a V-shaped structure, and the pressure rod and the two rotating frames are integrally formed.

[0014] In this technical solution, the rotating frame can stably drive the pressure bar to press the self-adhesive paper onto the die-cutting machine body, preventing the self-adhesive paper from moving during die-cutting.

[0015] In the above technical solution, the bottom of the unwinding frame is fixed to the top of the die-cutting machine body by screws, and a U-shaped groove is provided on the top of the unwinding frame.

[0016] In this technical solution, the unwinding frame can be used to hold the self-adhesive roll. The two ends of the self-adhesive roll can be inserted into the U-shaped groove of the unwinding frame, so that the self-adhesive roll can rotate between the two unwinding frames, which facilitates the unwinding and die-cutting of the self-adhesive roll on the die-cutting machine body. Under the action of gravity, the pressure roller will always be located on the die-cutting machine body, thereby continuously pressing the self-adhesive paper under the pressure roller and preventing the self-adhesive roll from becoming loose on the unwinding frame.

[0017] In the above technical solution, the electric slide rail is further fixedly connected to the top of the inner wall of the tool holder by screws, the electric slider is slidably connected to the bottom of the electric slide rail, the electric cylinder is located between the two rotating frames, and the electric cylinder is fixedly connected to the bottom of the electric slider by screws. The cutter includes: A first mounting bracket is fixed to the output end of an electric cylinder by screws. A cutting wheel is rotatably mounted inside the first mounting bracket, and a pressure wheel is rotatably mounted on one side of the first mounting bracket, near the conveyor roller.

[0018] In this technical solution, after the slitting roller finishes die-cutting the first section of self-adhesive paper, the output end of the electric cylinder will retract upward, thereby driving the first mounting frame, the slitting roller, and the pressure roller away from the die-cut self-adhesive paper. Subsequently, after the second section of self-adhesive paper to be die-cut moves below the slitting roller, the electric cylinder will drive the slitting roller to move downward and die-cut the self-adhesive paper. This process is repeated, thereby stabilizing the die-cutting of the self-adhesive paper through the slitting roller.

[0019] In the above technical solution, a rectangular groove is further provided on the top of the die-cutting machine body, and the bottom end of the rotating frame is located in the rectangular groove.

[0020] In this technical solution, one side of the rotating frame enters the rectangular groove when the rotating frame rotates, while the other side separates upward from the rectangular groove. When one side of the rotating frame enters the rectangular groove, the rolling roller contacts the top of the die-cutting machine body, thereby keeping the self-adhesive paper on the die-cutting machine body always between the two rotating frames, preventing the self-adhesive paper from being misaligned on the die-cutting machine body.

[0021] The beneficial effects of this utility model are: 1. The die-cutting device for self-adhesive labels utilizes the cooperation between the rotating frame, flattening roller, conveying roller, and pressure bar on the cutter holder. The conveying roller feeds the self-adhesive paper downwards towards the cutter and cuts it. The rotating frame then drives the pressure bar to rotate, pressing one end of the self-adhesive paper during die-cutting. This prevents the self-adhesive paper from moving synchronously with the cutter during die-cutting, thus affecting the die-cutting accuracy. Simultaneously, the flattening roller flattens the top of the self-adhesive paper to be die-cut, preventing wrinkles that could affect the die-cutting quality.

[0022] 2. The die-cutting device for this self-adhesive label uses pressure rollers to continuously press the self-adhesive paper onto the die-cutting machine body during unwinding, thereby achieving a tensioning effect and preventing the self-adhesive roll on the unwinding frame from becoming loose and unable to be unwound.

[0025] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0026] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0027] Example 1: This example provides a die-cutting device for self-adhesive labels, including a die-cutting machine body 10. An electric slide rail 21, an electric slider 12, and an electric cylinder 13 are provided above the die-cutting machine body 10. The output end of the electric cylinder 13 is equipped with a cutter. The device also includes: The blade holder 11 is fixedly installed on the top of the die-cutting machine body 10, and the electric slide rail 21, electric slider 12 and electric cylinder 13 are all located inside the blade holder 11. Two rotating frames 15 are provided below the cutter, and a pressure rod 17, a conveying roller 22 and several flattening rollers 16 are provided between the two rotating frames 15. Two unwinding frames 18 are set on the top of the die-cutting machine body 10, and a connecting plate 19 is rotatably installed on one side of each of the two unwinding frames 18, and a pressure roller 20 is rotatably installed between the two connecting plates 19. The power unit is located on the die-cutting machine body 10 and is used to drive the rotating frame 15 to rotate in both directions and to drive the conveyor roller 22 to rotate.

[0028] It is worth noting that the electric slide rail 21 and electric slider 12 involved in this utility model are existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the structure and working principle of the electric slide rail 21 and electric slider 12.

[0029] The process involves inserting both ends of the self-adhesive film roll between two unwinding frames 18. Then, one end of the roll is passed under the pressure roller 20, the flattening roller 16, and the conveyor roller 22. The first motor 14 is then turned on, causing the output of the first motor 14 to rotate the rotating frame 15 towards the flattening roller 16. The rotating frame 15 then rotates the second motor, the pressure rod 17 of the conveyor roller 22, and several flattening rollers 16 until one side of the rotating frame 15 is engaged in a rectangular groove. Simultaneously, the flattening roller 16 and the conveyor roller 22 press the self-adhesive paper onto the die-cutting machine body 10. At this point, the second motor is turned on, causing the conveyor roller 22 to rotate. Under the action of friction, the rotating conveyor roller 22 presses the self-adhesive paper downwards towards the slitting wheel. When the operator activates the electric slide rail 21, the electric cylinder 13, and the first motor 14, the electric slide rail 21 can drive the electric slider 12 and the electric cylinder 13 to move back and forth along the bottom of the electric slide rail 21. This causes the first mounting frame, the cutting wheel, and the pressure wheel to die-cut the self-adhesive paper unfolded below. When the output end of the electric cylinder 13 extends downward, it will drive the first mounting frame, the cutting wheel, and the pressure wheel to move towards the self-adhesive paper below. This allows the cutting wheel to die-cut the self-adhesive paper below while moving left and right. The output end of the first motor 14 will drive the rotating frame 15 to rotate in the opposite direction until the bottom of the pressure rod 17 presses down on the self-adhesive paper being die-cut, ensuring that the self-adhesive paper being die-cut will not move with the left and right movement of the cutting wheel.

[0030] Through the cooperation between the rotating frame 15, the flattening roller 16, the conveying roller 22 and the pressure rod 17 on the blade holder 11, the self-adhesive paper is conveyed downwards to the cutter by the conveying roller 22 and die-cut by the cutter. Then, the rotating frame 15 drives the pressure rod 17 to rotate, thereby pressing one end of the self-adhesive paper when it is being die-cut by the cutter, preventing the self-adhesive paper from moving synchronously due to the movement of the cutter during die-cutting, thus affecting the die-cutting accuracy.

[0031] Example 2: This example provides a die-cutting device for self-adhesive labels. In addition to the technical solutions of the above examples, it also has the following technical features, including a power component: The first motor 14 is fixedly installed on one side of the tool holder 11 and located below the electric cylinder 13. The output end of the first motor 14 passes through one side of the tool holder 11 and is fixedly connected to one of the rotating frames 15. The output end of the first motor 14 is rotatably connected to the tool holder 11. The second motor is fixedly installed on one side of one of the rotating frames 15. The output end of the second motor passes through one side of one of the rotating frames 15 and is coaxially connected to the conveying roller 22. The output end of the second motor is rotatably connected to one of the rotating frames 15.

[0032] The output of the first motor 14 can rotate in both the forward and reverse directions, thereby stably controlling the rotating frame 15 to reciprocate on the die-cutting machine body 10, which in turn drives the rolling roller 16 and the pressure rod 17 to roll out and fix the self-adhesive paper on the die-cutting machine body 10.

[0033] Example 3: This example provides a die-cutting device for self-adhesive labels. In addition to the technical solutions of the above examples, it also has the following technical features: a plurality of rolling rollers 16 are arranged at equal intervals, and the two ends of the rolling rollers 16 are rotatably connected to two rotating frames 15 respectively. The conveying roller 22 is located between the plurality of rolling rollers 16 and the cutter holder 11, and one end of the conveying roller 22 is rotatably connected to one of the rotating frames 15.

[0034] Among them, when the flattening roller 16 presses the self-adhesive paper onto the die-cutting machine body 10, it can flatten the wrinkles on the self-adhesive paper and avoid the wrinkles on the self-adhesive paper affecting the die-cutting effect.

[0035] Example 4: This example provides a die-cutting device for self-adhesive labels. In addition to the technical solutions of the above examples, it also has the following technical features: the rotating frame 15 has a V-shaped structure, and the pressure rod 17 and the two rotating frames 15 are integrally formed.

[0036] The rotating frame 15 can stably drive the pressure rod 17 to press the self-adhesive paper on the die-cutting machine body 10, preventing the self-adhesive paper from moving during die-cutting.

[0037] Example 5: This example provides a die-cutting device for self-adhesive labels. In addition to the technical solutions of the above examples, it also has the following technical features: the bottom of the unwinding frame 18 is fixed to the top of the die-cutting machine body 10 by screws, and a U-shaped groove is provided on the top of the unwinding frame 18.

[0038] The unwinding frame 18 is used to hold the self-adhesive film rolls. Both ends of the self-adhesive film rolls can be inserted into the U-shaped grooves of the unwinding frame 18, so that the self-adhesive film rolls can rotate between the two unwinding frames 18. This facilitates the unwinding and die-cutting of the self-adhesive film rolls on the die-cutting machine body 10. Under the action of gravity, the pressure roller 20 will always be located on the die-cutting machine body 10, thereby continuously pressing the self-adhesive paper below the pressure roller 20 and preventing the self-adhesive film rolls from becoming loose on the unwinding frame 18.

[0039] Example 6: This example provides a die-cutting device for self-adhesive labels. In addition to the technical solutions of the above examples, it also has the following technical features: the electric slide rail 21 is fixedly connected to the top of the inner wall of the knife holder 11 by screws; the electric slider 12 is slidably connected to the bottom of the electric slide rail 21; the electric cylinder 13 is located between the two rotating frames 15, and the electric cylinder 13 is fixedly connected to the bottom of the electric slider 12 by screws. The cutting blade includes: The first mounting frame is fixed to the output end of the electric cylinder 13 by screws. A cutting wheel is rotatably mounted inside the first mounting frame, and a pressure wheel is rotatably mounted on one side of the first mounting frame and the side closest to the conveyor roller 22.

[0040] After the slitting wheel finishes die-cutting the first section of self-adhesive paper, the output end of the electric cylinder 13 retracts upward, thereby driving the first mounting frame, the slitting wheel, and the pressure roller away from the die-cut self-adhesive paper. Subsequently, after the second section of self-adhesive paper to be die-cut moves below the slitting wheel, the electric cylinder 13 drives the slitting wheel to move downward and die-cut the self-adhesive paper. This process is repeated to stably die-cut the self-adhesive paper through the slitting wheel.

[0041] Example 7: This example provides a die-cutting device for self-adhesive labels. In addition to the technical solutions of the above examples, it also has the following technical features: a rectangular groove is provided on the top of the die-cutting machine body 10, and the bottom end of the rotating frame 15 is located in the rectangular groove.

[0042] One side of the rotating frame 15 enters the rectangular groove when the rotating frame 15 rotates, while the other side separates upward from the rectangular groove. When one side of the rotating frame 15 enters the rectangular groove, the flattening roller 16 contacts the top of the die-cutting machine body 10, thereby keeping the self-adhesive paper on the die-cutting machine body 10 always between the two rotating frames 15, preventing the self-adhesive paper from being misaligned on the die-cutting machine body 10.

[0043] Working principle: First, the operator inserts both ends of the self-adhesive roll between the two unwinding frames 18. Then, one end of the self-adhesive roll is passed under the pressure roller 20, the flattening roller 16, and the conveyor roller 22. Next, the first motor 14 is turned on. The output of the first motor 14 drives the rotating frame 15 to rotate towards the flattening roller 16. The rotating frame 15 drives the second motor, the pressure rod 17 of the conveyor roller 22, and several flattening rollers 16 to rotate until one side of the rotating frame 15 is inserted into the rectangular groove. Simultaneously, the flattening roller 16 and the conveyor roller 22 press the self-adhesive paper onto the die-cutting machine body 10. At this point, the operator... When the second motor is turned on, it drives the conveyor roller 22 to rotate. Under the action of friction, the rotating conveyor roller 22 squeezes the self-adhesive paper and moves it downwards towards the slitting roller. Subsequently, the operator activates the electric slide rail 21, the electric cylinder 13, and the first motor 14. When the operator activates the electric slide rail 21, it drives the electric slider 12 and the electric cylinder 13 to move back and forth along the bottom of the electric slide rail 21, thereby driving the first mounting frame, the slitting roller, and the pressure roller to die-cut the self-adhesive paper unfolded below. When the output end of the electric cylinder 13 extends downwards, it drives the first mounting frame, the slitting roller, and the pressure roller. The self-adhesive paper moves downwards, causing the slitting roller to die-cut the lower self-adhesive paper as it moves left and right. Simultaneously, the output of the first motor 14 drives the rotating frame 15 to rotate in the opposite direction until the bottom of the pressure rod 17 presses down on the die-cutting self-adhesive paper, ensuring that the die-cutting self-adhesive paper does not move with the left and right movement of the slitting roller. After the first segment of the self-adhesive paper is die-cut by the slitting roller, the output of the first motor 14 drives the rotating frame 15 to rotate towards the flattening roller 16 until the flattening roller 16 and the conveying roller 22 press down on the lower self-adhesive paper. At the same time, the pressure rod 17... 7 will move upwards away from the die-cut self-adhesive paper. Then, the second motor will drive the conveyor roller 22 to rotate, which will drive the self-adhesive roll on the unwinding frame 18 to continue unwinding until the second section of self-adhesive paper to be die-cut moves to below the electric cylinder 13. Then, the output end of the first motor 14 will drive the rotating frame 15 to rotate towards the pressure rod 17, and the pressure rod 17 will press down the self-adhesive paper below to prevent the self-adhesive paper from moving during die-cutting. After the second section of self-adhesive paper is die-cut, the same method will be used to continue die-cutting each subsequent section of self-adhesive paper until all the self-adhesive paper is die-cut.
