Description

Technical Field

[0001] This utility model relates to the field of paper label production technology, specifically a die-cutting mold for paper labels. Background Technology

[0002] Paper labels are labels made from paper materials, typically coated paper or other special types of paper. Coated paper labels are widely used across various industries due to their low cost and wide printability, but their disadvantages include being non-waterproof, non-oilproof, and easily torn. Lamination can enhance their waterproof and oil-proof properties. Paper labels are widely used in various industries, such as pharmaceuticals, food, beverages, electrical appliances, and stationery. Due to their low cost and wide printability, paper labels hold an important position in the market. The production and processing of paper labels utilizes die-cutting molds, which are specialized tools used to cut and cut paper labels.

[0003] For example, utility model application No. 202223032103.5 discloses a high-efficiency paper label punching die, which is applicable to an electric clamp-type cold cutting flying saw. The die automatically removes waste material from the clearance hole by moving the needle downwards. At the same time, the annular blades around the needle, which are adapted to the size of the clearance hole, cut the waste material that is not completely punched again to prevent the waste material from sticking to the label. This method eliminates the need for manual removal of waste material, saves time and labor, and improves the speed of production and processing. However, when processing paper labels, it is difficult to tighten and fix the label tape, which may cause the label tape to wrinkle or shift during operation, thus affecting the accuracy of the processing effect.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a die-cutting mold for paper labels. Utility Model Content

[0005] The purpose of this invention is to provide a die-cutting mold for paper labels to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-cutting mold for paper labels, comprising a die frame assembly and a tensioning frame. An upper die assembly is horizontally installed in the middle of the inner side of the die frame assembly. The tensioning frame is symmetrically installed on the left and right sides of the upper die assembly. A pressure plate assembly is symmetrically connected to the bottom of the upper die assembly. A lower die assembly is located directly below the upper die assembly. A chip collection drawer is connected to the bottom of the lower die assembly. The tensioning frame includes a tensioning roller, a double-segment support arm, and a fixing frame. Both ends of the tensioning roller are connected to and installed with double-segment support arms. The end of the double-segment support arm away from the tensioning roller is connected to the fixing frame.

[0007] Furthermore, the mold frame assembly includes a pressing mechanism, support columns, and a base. Support columns are vertically installed at the four opposite corners of the bottom of the pressing mechanism, and the bottom of the support columns is connected to the base.

[0008] Furthermore, the upper mold assembly includes an upper mold body, a first cutting blade, and a second cutting blade. The first cutting blade is installed at one bottom end of the upper mold body, and the second cutting blade is installed at the other bottom end of the upper mold body.

[0009] Furthermore, the support columns are vertically inserted through the four opposite corners of the pressing mechanism, and the pressing mechanism and the support columns are slidably connected.

[0010] Furthermore, the pressure plate assembly includes an annular pressure plate, a spring telescopic rod, and an anti-slip ring. The spring telescopic rod is vertically installed at the top left and right ends of the annular pressure plate, and an anti-slip ring is installed on the bottom surface of the spring telescopic rod.

[0011] Furthermore, the spring telescopic rods are equidistantly arranged and installed at one end of the top of the annular pressure plate, and the end of the spring telescopic rod away from the annular pressure plate is fixedly installed on the bottom surface of the upper mold body. The pressure plate assembly is respectively arranged around the first cutter and the second cutter.

[0012] Furthermore, the lower mold assembly includes a lower mold body, a first punching plate, and a second punching plate. The first punching plate is installed at one end of the top surface of the lower mold body, and the second punching plate is installed at the other end of the top surface of the lower mold body.

[0013] Furthermore, the chip collection drawer is installed between the lower mold body and the base. The middle portions of the first and second punching plates are respectively provided with hole structures that match the surface structures of the first and second cutters, and the hole structures in the middle portions of the first and second punching plates are interconnected with the interior of the chip collection drawer.

[0014] This utility model provides a die-cutting mold for paper labels, which has the following advantages:

[0015] 1. This utility model, by symmetrically installing tensioning frames on the left and right sides of the upper mold assembly, when the pressing mechanism drives the entire upper mold assembly to move vertically downward along the surface of the support column, it will drive the tensioning frames on both sides to move downward synchronously, thereby causing the tensioning rollers to press down on both ends of the paper label tape, thus achieving staged tensioning of the label tape located between the upper and lower mold assemblies. The tensioning rollers can be flexibly oscillated and adjusted under the structural movement of the double-segment support arm, thereby adjusting to a suitable pressing position. In addition, by installing pressure plate assemblies at the left and right ends of the bottom of the upper mold assembly, they move synchronously with the upper mold assembly, and press the anti-slip ring at the bottom of the annular pressure plate against the surface of the label strip being punched, thereby forming a pressing and fixing, thus maximizing the flatness and stability of the label tape during punching, ensuring the accuracy of punching. The spring telescopic rod acts as a structural buffer and support between the upper and lower mold assemblies, avoiding unnecessary structural interference.

[0016] 2. This utility model features a first and second cutting blade installed at the bottom of the upper mold body, and a first and second punching plate installed at the top of the lower mold body. Holes matching the surface structures of the first and second cutting blades are formed on their middle surfaces, allowing for interference fit between the first and second cutting blades during vertical punching. This structure ensures effective punching and enables secondary punching, maximizing punching efficiency and preventing incomplete punching. Furthermore, a chip collection drawer is included, with the holes on the surfaces of the first and second punching plates communicating with its interior. After the first and second cutting blades interfere with the first and second punching plates, the resulting paper scraps fall directly into the drawer for easy maintenance and cleaning.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1 to 4 As shown, a die-cutting mold for paper labels includes a die frame assembly 1 and a tensioning frame 3. An upper die assembly 2 is horizontally mounted on the inner center of the die frame assembly 1. The tensioning frame 3 is symmetrically mounted on the left and right sides of the upper die assembly 2. A pressure plate assembly 4 is symmetrically connected to the bottom of the upper die assembly 2. A lower die assembly 5 is located directly below the upper die assembly 2, and a chip collection drawer 6 is connected to the bottom of the lower die assembly 5. The tensioning frame 3 includes a tension roller 301, a double-segment support arm 302, and a fixing frame 303. Both ends of the tension roller 301 are connected to the double-segment support arm 302, and the end of the double-segment support arm 302 furthest from the tension roller 301 is connected to the fixing frame 303. The pressure plate assembly 4 includes an annular pressure plate 401, a spring telescopic rod 402, and an anti-slip ring 403. The top of the annular pressure plate 401... Spring telescopic rods 402 are vertically installed at both ends, and anti-slip rings 403 are installed on the bottom surface of the spring telescopic rods 402. The spring telescopic rods 402 are equidistantly arranged at one end of the top of the annular pressure plate 401, and the end of the spring telescopic rods 402 away from the annular pressure plate 401 is fixedly installed on the bottom surface of the upper mold body 201. The pressure plate assembly 4 is respectively set around the first cutter 202 and the second cutter 203. When the pressing mechanism 101 drives the entire upper mold assembly 2 to move vertically downward along the surface of the support column 102 in the vertical direction, it will drive the tensioning frame 3 on both sides to move downward synchronously, so that the tensioning roller 301 presses down on both ends of the paper label tape, thereby realizing the staged tensioning treatment of the label tape located between the upper mold assembly 2 and the lower mold assembly 5.

[0024] like Figures 1 to 4As shown, the mold frame assembly 1 includes a pressing mechanism 101, support columns 102, and a base 103. Support columns 102 are vertically installed at the four opposite corners of the bottom of the pressing mechanism 101, and the bottom of the support columns 102 is connected to the base 103. The upper mold assembly 2 includes an upper mold body 201, a first cutting blade 202, and a second cutting blade 203. The first cutting blade 202 is installed at one end of the bottom of the upper mold body 201, and the second cutting blade 203 is installed at the other end of the bottom of the upper mold body 201. The support columns 102 vertically penetrate the four opposite corners of the pressing mechanism 101, and the pressing mechanism 101 and the support columns 102 are slidably connected. The lower mold assembly 5 includes a lower mold body 501, a first punching plate 502, and a second punching plate 503. A base 103 is installed at one end of the top surface of the lower mold body 501. A first punching plate 502 is provided, and a second punching plate 503 is installed at the other end of the top surface of the lower mold body 501. A chip collection drawer 6 is installed between the lower mold body 501 and the base 103. The middle parts of the first punching plate 502 and the second punching plate 503 are respectively provided with hole structures that match the surface structures of the first cutter 202 and the second cutter 203. The hole structures in the middle parts of the first punching plate 502 and the second punching plate 503 are interconnected with the interior of the chip collection drawer 6. The middle surfaces of the first punching plate 502 and the second punching plate 503 are provided with hole structures that match the surface structures of the first cutter 202 and the second cutter 203, so that the first cutter 202 and the second cutter 203 can be interference-fitted with the first punching plate 502 and the second punching plate 503 during vertical punching.

[0025] In summary, as Figures 1 to 4 As shown, when using the paper label punching die, the paper strip of the paper label to be punched is first passed horizontally between the upper die assembly 2 and the lower die assembly 5. Then, according to the processing needs, the tension roller 301 is folded to a suitable angle position by adjusting the double-segment support arm 302 between the tension roller 301 and the fixing frame 303.

[0026] After the tensioning frames 3 on both sides of the upper mold assembly 2 are adjusted, the pressing mechanism 101 is started. Under the extension and contraction of its structure, the upper mold assembly 2 connected to the bottom is pushed, so that the first cutter 202 and the second cutter 203 at the bottom of the upper mold body 201 are pressed down vertically and are interference-fitted with the first punching plate 502 and the second punching plate 503 on the surface of the lower mold body 501.

[0027] During this period, as the upper mold assembly 2 is pressed down, the tensioning frame 3 and the pressure plate assembly 4 at the bottom of both sides will move synchronously, so that the tensioning roller 301 abuts against the two ends of the paper label tape, and the anti-slip ring 403 at the bottom of the annular pressure plate 401 abuts against the surface of the label tape, thereby forming a tensioning and fixing effect until the first cutter 202 and the second cutter 203 punch and cut the surface of the label tape. The generated paper scraps will pass through the holes on the surface of the first punching plate 502 and the second punching plate 503 and fall into the inside of the scrap collection drawer 6 between the lower mold body 501 and the base 103 for centralized collection, which is convenient for later maintenance and reduces the scattering of paper scraps.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
