Description

Technical Field

[0001] This utility model mainly relates to the field of die-cutting equipment technology, specifically to an intermittent die-cutting machine. Background Technology

[0002] In daily life, electronic tags are the carriers of RFID technology. The most basic electronic tag system consists of three parts: tag, reader, and antenna. The tag is composed of coupling element and chip. Each tag has a unique electronic code. High-capacity electronic tags have user-writable storage space and are attached to objects to identify target objects.

[0003] Currently, the production of electronic tags typically requires a die-cutting device. After the roll of material is unloaded, it is die-cut and then rewound. However, in existing die-cutting devices, the die-cutting rollers are generally installed in fixed positions, making it inconvenient to adjust the pressure between the rollers and the bottom of the roll material. This makes die-cutting difficult and sometimes results in incomplete cutting, hindering the subsequent separation of finished products from waste material during rewinding, impacting subsequent production steps, and negatively affecting practical use. Therefore, it is necessary to propose an improvement measure to solve the above-mentioned technical problems.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides an intermittent die-cutting machine to solve the technical problems existing in the background art.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: an intermittent die-cutting machine, comprising a fixed frame, with a feeding roller and a finished product winding roller rotatably mounted at opposite ends of the front side of the fixed frame, a waste material winding roller rotatably mounted above the finished product winding roller, a correction assembly positioned above the feeding roller, a driven base shaft mounted at the center of the front side of the fixed frame, a die-cutting roller rotatably mounted above the drive base shaft, and a pressure plate assembly positioned above the die-cutting roller to apply pressure to it; A first traction bottom shaft is rotatably mounted on the side of the die-cutting roller closest to the unloading roller, and a second traction bottom shaft is rotatably mounted on the side of the die-cutting roller closest to the finished product take-up roller. Multiple rotatable guide rollers are installed at corresponding positions on the front side of the fixed frame. The rolled material on the unloading roller passes through the guide rollers and the correction assembly and the first traction bottom shaft to the space between the die-cutting roller and the power bottom shaft. Die-cutting is achieved by the die-cutting roller. After die-cutting, the material passes through the guide rollers and the second traction bottom shaft. The finished product is taken up on the finished product take-up roller, and the waste material is taken up on the waste material take-up roller.

[0009] Furthermore, a front frame wall panel is installed at the front of the fixed frame. The correction assembly includes a correction mounting frame, which is fixed between the fixed frame and the front frame wall panel and located above the feeding roller. Two rotatable guide rollers are installed on the top of the correction mounting frame. A slide cylinder is installed on one side of the correction mounting frame. A U-shaped correction rod is installed on the movable seat of the slide cylinder. The rolled material on the feeding roller passes through the guide rollers and is then inserted into and passes through the U-shaped correction rod. Front and rear correction is achieved through the U-shaped correction rod.

[0010] Furthermore, the power base shaft is rotatably mounted between the fixed frame and the front frame wall panel, and a drive motor is installed at a corresponding position inside the fixed frame. One end of the power base shaft is connected to the output shaft of the drive motor.

[0011] Furthermore, vertical grooves are provided at corresponding positions on the fixed frame and the front frame wall panel, and sliders are slidably installed in the grooves. The two ends of the die-cutting roller are rotatably installed on the sliders on both sides, and the roll material passes through the space between the die-cutting roller and the power shaft. The pressure plate assembly includes an inverted U-shaped pressure plate, and the bottom ends of the pressure plate are respectively fixed to the fixed frame and the front frame wall panel. Nuts are installed on both sides of the pressure plate, and a pressure handwheel is installed on the internal thread of the nut. A pressure block is provided at the bottom end of the pressure handwheel through the nut. An optical shaft is installed between the two pressure blocks, and two deep groove ball bearings are installed at the bottom of the pressure blocks. The die-cutting roller is pressed against the bottom of the two deep groove ball bearings.

[0012] Furthermore, a rotatable top roller is installed above both the first and second traction shafts. The two ends of the top roller are rotatably mounted on two mounting seats via bearings. One side of each mounting seat is rotatably mounted on the fixed frame and the front frame wall plate via short shafts. The other side of each mounting seat is hinged with a telescopic cylinder. The other ends of the two telescopic cylinders are rotatably mounted on the fixed frame and the front frame wall plate, respectively. The position of the top roller is adjusted by the telescopic cylinders.

[0013] Furthermore, after the roll material passes through the top of the second traction bottom shaft, the die-cut finished product is wound onto the finished product take-up roller, and the die-cut waste material passes through the glue roller above the second traction bottom shaft and is wound onto the waste material take-up roller.

[0014] 3. Beneficial effects:

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0016] This utility model is reasonably designed. By vertically adjusting the die-cutting roller during installation using a slider and applying appropriate pressure to the roller using a pressure plate assembly, the die-cutting roller can effectively press against the roll material passing beneath it. This ensures the die-cutting effect of the roll material and prevents incomplete cutting, guaranteeing the proper separation of finished and scrap materials during subsequent winding. It is convenient to use. Furthermore, the correction component can correct the front and rear deviations of the roll material. A gluing roller is also provided above the first and second traction shafts. The installation position of the gluing roller is adjusted and controlled by a telescopic cylinder. This allows the gluing roller to be pressed against the top of the first or second traction shaft when the feed roller, finished product winding roller, or scrap material winding roller needs to be replaced, reducing or stopping the conveying of the roll material and facilitating replacement operations. Its overall design is ingenious, easy to use, and highly practical.

[0017] It should be noted that the structures not described in this utility model are the same as or can be implemented using existing technology, and will not be elaborated here, as they do not involve the design points and improvement directions of this utility model. Attached Figure Description

[0028] See attached document Figure 1-4 An intermittent die-cutting machine according to this embodiment includes a fixed frame 1. A feeding roller 17 and a finished product winding roller 3 are rotatably mounted at opposite ends of the front side of the fixed frame 1. A waste material winding roller 4 is rotatably mounted above the finished product winding roller 3. A correction assembly is positioned above the feeding roller 17. A driven base shaft 16 is mounted at the center of the front side of the fixed frame 1. A die-cutting roller 8 is rotatably mounted above the drive base shaft 16. A pressure plate assembly 9 is positioned above the die-cutting roller 8 to apply pressure. A first traction base shaft 10 is rotatably mounted on the side of the die-cutting roller 8 closest to the feeding roller 17, and a second traction base shaft 11 is rotatably mounted on the side of the die-cutting roller 8 closest to the finished product winding roller 3. Multiple rotatable guide rollers 5 are mounted at corresponding positions on the front side of the fixed frame 1. The specific distribution of the guide rollers 5 is as follows... Figure 2 As shown, it is used to guide the conveying of the roll material. The roll material on the unloading roller 17 passes through the correction assembly and the first traction bottom shaft 10 via the guide roller 5 to the space between the die-cutting roller 8 and the power bottom shaft 16. It is die-cut by the die-cutting roller 8, and after die-cutting, it passes through the second traction bottom shaft 11 via the guide roller 5. The finished product is wound on the finished product winding roller 3, and the waste material is wound on the waste material winding roller 4.

[0029] Specifically, a front frame wall panel 2 is installed at the front of the fixed frame 1. The correction assembly includes a correction mounting frame 6, which is fixed between the fixed frame 1 and the front frame wall panel 2 and located above the feed roller 17. Two rotatable guide rollers 5 are installed on the top of the correction mounting frame 6. A slide cylinder is installed on one side of the correction mounting frame 6. A U-shaped correction rod 7 is installed on the movable seat of the slide cylinder. The rolled material on the feed roller 17 passes through the guide rollers 5 and is then inserted into and passes through the U-shaped correction rod 7. The front and rear correction of the rolled material is achieved by adjusting the position of the U-shaped correction rod 7. It is worth noting that the U-shaped correction rod 7 can be adjusted in many ways. For example, a threaded screw can be rotatably mounted on one side of the correction mounting bracket 6, and a moving block can be threaded onto the threaded screw. The U-shaped correction rod 7 can be mounted on the moving block, and the threaded screw can be rotated manually or by driving it with a motor, thus adjusting the movement of the U-shaped correction rod 7. A control panel can also be provided at the bottom of the correction mounting bracket 6 to control the movement of the U-shaped correction rod 7.

[0030] The power shaft 16 is rotatably mounted between the fixed frame 1 and the front frame wall panel 2. A drive motor is installed in the corresponding position inside the fixed frame 1. One end of the power shaft 16 is connected to the output shaft of the drive motor, and the power shaft 16 is driven to rotate by the drive motor.

[0031] Vertical grooves are provided at corresponding positions on the fixed frame 1 and the front frame wall panel 2. Sliders are slidably installed in the grooves. The two ends of the die-cutting roller 8 are rotatably installed on the sliders on both sides. The roll material passes through the die-cutting roller 8 and the power base shaft 16. The pressure plate assembly 9 includes an inverted U-shaped pressure plate 901. The bottom ends of the pressure plate 901 are respectively fixed to the fixed frame 1 and the front frame wall panel 2. Nuts 903 are installed on both sides of the pressure plate 901. A pressure handwheel 902 is installed on the internal thread of the nut 903. A pressure block 904 is provided at the bottom end of the pressure handwheel 902 through the nut 903. An optical shaft 906 is installed between the two pressure blocks 904. Two deep groove ball bearings 905 are installed at the bottom of the pressure blocks 904. The die-cutting roller 8 is pressed against the bottom of the two deep groove ball bearings 905. The deep groove ball bearings 905 can press the die-cutting roller 8 and rotate together. By using the pressure plate assembly 9 to apply pressure to the die-cutting roller 8, the die-cutting roller 8 presses the rolled material and rolls, thereby smoothly realizing the die-cutting operation. It is worth noting that the pressure plate 901 has corresponding waist-shaped holes on both sides, the nut 903 is installed in the waist-shaped hole and can be moved and adjusted, and the optical axis 906 also slides through the pressure blocks 904 on both sides, so that the distance between the two pressure blocks 904 can be adjusted to suit die-cutting rollers 8 of different lengths.

[0032] A rotatable top roller 12 is installed above both the first traction shaft 10 and the second traction shaft 11. The two ends of the top roller 12 are rotatably mounted on two mounting seats 14 via bearings. One side of each mounting seat 14 is rotatably mounted on the fixed frame 1 and the front frame wall plate 2 via short shafts 15. The other side of each mounting seat 14 is hinged with a telescopic cylinder 13. The other ends of each telescopic cylinder 13 are rotatably mounted on the fixed frame 1 and the front frame wall plate 2. The position of the top roller 12 is adjusted by the telescopic cylinder 13 so that when it is necessary to replace the feed roller 17, the finished product winding roller 3, or the waste material winding roller 4, the top roller 12 can be pressed against the top of the first traction shaft 10 or the second traction shaft 11 to reduce or stop the conveying of the rolled material, facilitating the replacement operation. After the roll material passes through the top of the second traction bottom shaft 11, the die-cut finished product is wound onto the finished product take-up roller 3, and the die-cut waste material passes through the glue roller 12 above the second traction bottom shaft 11 and is wound onto the waste material take-up roller 4.

[0033] Each end of the finished product winding roller 3 and the waste material winding roller 4 can be equipped with a drive source, such as a motor, to drive the finished product winding roller 3 and the waste material winding roller 4 to rotate and wind up the die-cut rolls and waste materials. The die-cutting roller 8 can be a conventional die-cutting roller. Specifically, in this embodiment, an intermittent die-cutting roller with blades intermittently installed can be used to achieve intermittent die-cutting. An operation box is provided at the front of the front frame wall panel 2, and a controller can be provided inside the operation box. It can be electrically connected to various electrical components of this device, and an operation button can be provided on the top of the operation box for controlling its operation.

[0034] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
