Abstract
Description
Technical Field
[0001] This utility model belongs to the field of flatbed die-cutting of packaging and printing products, specifically relating to a reusable flatbed die-cutting frame. Background Technology
[0002] Packaging printed materials are die-cut and creasingd using automatic die-cutting equipment to form small sheets of printed materials. These printed materials are then folded and glued into finished packaging using automated packaging equipment or manually. Flatbed die-cutting is the mainstream process for die-cutting and creasing traditional packaging printed materials. The key structures of the die-cutting station include three parts: the die-cutting frame, the die-cutting plate (upper plate), and the die-cutting base plate (lower plate). The die-cutting plate is equipped with die-cutting and creasing tools, which are generally made of high-quality steel. The die-cutting base plate is equipped with creasing line bottom molds corresponding to the die-cutting plate. The die-cutting frame includes a border, a back plate, mounting slots, and several fixing screws, keys, and pins. The back plate fixed inside the frame directly contacts the back of the die-cutting plate, and the bottom ends of the die-cutting and creasing tools directly press against the back plate.
[0003] After prolonged die-cutting use, the back plate within the die-cutting frame, under the continuous pressure of the die-cutting process, will develop noticeable grooves at the corresponding positions of the die-cutting and creasing blades. This is especially true for general-purpose frames, where the blade lines of different sizes of packaging printing die-cutting plates create irregular and uneven grooves. During die-cutting production, this results in uneven die-cutting and creasing pressure, reduced product quality, and blade damage. Furthermore, due to the inherent limitations of current die-cutting technology and equipment design, the die-cutting frame has an asymmetrical structure, making it impossible to flip and reassemble as a whole, and thus not directly reused. Under current technological conditions, this technical challenge can only be addressed by purchasing or replacing the frame, leading to increased production costs and material waste. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a reusable flatbed die-cutting frame to solve the problem of frame waste.
[0005] This utility model is achieved through the following technical solution:
[0006] A reusable flatbed die-cutting frame includes a frame border and a back plate. The frame border is rectangular, formed by two horizontal borders and two vertical borders. Screw holes are fixedly provided on the horizontal borders, and screw holes and positioning holes are fixedly provided on the vertical borders. The back plate has the same shape as the frame border. Forward screw holes corresponding to the screw holes on the horizontal borders are provided on the two horizontal borders of the back plate, and forward screw holes and forward positioning holes corresponding to the screw holes and positioning holes on the two vertical borders of the back plate are provided on the two vertical borders. The two vertical borders are designated as a first vertical border and a second vertical border, and the two vertical borders of the back plate are designated as a first vertical border and a second vertical border, respectively. The position and size of the forward screw holes on the first vertical border correspond to the screw holes and positioning holes on the first vertical border. The screw holes are consistent; the position and size of the positive positioning hole on the first longitudinal edge are consistent with the positioning hole on the first longitudinal frame; the position and size of the positive screw hole on the second longitudinal edge are consistent with the screw hole on the second longitudinal frame; the position and size of the positive positioning hole on the second longitudinal edge are consistent with the positioning hole on the second longitudinal frame; the two longitudinal edges on both sides of the back plate are also provided with reverse screw holes and reverse positioning holes; the position and size of the reverse screw hole on the first longitudinal edge are consistent with the screw hole on the second longitudinal frame; the position and size of the reverse positioning hole on the first longitudinal edge are consistent with the positioning hole on the second longitudinal frame; the position and size of the reverse screw hole on the second longitudinal edge are consistent with the screw hole on the first longitudinal frame; the position and size of the reverse positioning hole on the second longitudinal edge are consistent with the positioning hole on the first longitudinal frame.
[0007] The positioning hole is equipped with a positioning pin, and the back plate is positioned with the frame edge through the front positioning hole or the back positioning hole.
[0008] It also includes bolts, which secure the back plate to the frame edge via screw holes and forward or reverse screw holes.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] This invention designs back positioning holes and back screw holes on the back plate of the die-cutting frame, so that the back plate can still be aligned with the frame edge and fastened to the original frame edge after being independently flipped. The use function of the die-cutting frame is not affected after the back plate is flipped, realizing the secondary use of the back plate, increasing the durability by 100%, and reducing waste.
[0011] The die-cutting frame of this utility model has a simple structure and is easy to operate. The back plate is fixed by a certain number of bolts and fixing pins, and it can be easily disassembled with only simple tools such as screwdrivers. Attached Figure Description
