Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, specifically to a die-cutting knife for conductive cloth. Background Technology

[0002] With the rapid development of the modern electronics industry, the integration and operating speed of electronic devices are constantly increasing, leading to increasingly prominent electromagnetic interference problems. Conductive cloth, as a high-performance electromagnetic shielding material, has been widely used in electronic devices, effectively preventing electromagnetic radiation from interfering with internal electronic components and ensuring stable operation. However, the challenges in the die-cutting process of conductive cloth greatly limit its application and promotion in high-end electronics.

[0003] Traditional conductive fabric die-cutting processes face numerous challenges. One significant issue is the difficulty in cutting conductive fabric. Conductive fabric is typically formed from fiber cloth through special chemical or physical treatments, resulting in a complex and dense internal fiber structure. At room temperature, ordinary cutters struggle to quickly and effectively cut these fibers, requiring significant pressure and prolonged cutting time. This not only leads to low die-cutting efficiency and increased production costs but also accelerates cutter wear, necessitating frequent cutter replacements and further increasing both economic and time costs. Moreover, prolonged, high-intensity cutting pressure can cause localized deformation of the conductive fabric, affecting its subsequent performance. Simultaneously, the generation of burrs during conductive fabric die-cutting is a major industry problem. Burrs severely impact the appearance and performance of conductive fabric. From a materials perspective, if the fibers of the conductive fabric are not cleanly cut during the cutting process, some fibers are pulled out, forming irregular burrs. This is especially true for conductive fabrics with coarser fiber density and insufficient glue penetration, which are more prone to developing numerous irregular burrs after die-cutting. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a die-cutting knife for conductive cloth.

[0005] The objective of this utility model can be achieved through the following technical solution: a die-cutting knife for conductive cloth, including a knife holder, a knife template installed at the bottom of the knife holder, a cutting blade at the bottom of the knife template, a receiving groove between the knife holder and the knife template, a heat-conducting block in the receiving groove, an installation groove on the heat-conducting block, a heating element in the installation groove, and a heat insulation layer between the knife holder and the heat-conducting block.

[0006] Preferably, the mounting slot has an "S" shaped structure.

[0007] Preferably, the heating element is an electric heating tube.

[0008] Preferably, positioning grooves are provided on both sides of the receiving groove, and positioning blocks corresponding to the positioning grooves are provided on the heat-conducting block.

[0009] Preferably, the die template has a mounting hole, and a temperature probe is installed in the mounting hole.

[0010] Preferably, the space between the temperature probe and the wall of the mounting hole is filled with a thermally conductive medium.

[0011] The beneficial effects of this invention are as follows: the heat generated by the heating element is conducted to the cutting blade via the heat-conducting block, raising its temperature and easily cutting the complex and tightly packed fibers of the conductive cloth, solving the problem of difficult cutting at room temperature and significantly improving die-cutting efficiency. The heat insulation layer reduces heat transfer to the blade holder, concentrating heat on the cutting blade and reducing energy consumption. Furthermore, high-temperature cutting reduces blade wear, extending its service life, while preventing fiber pulling and burr formation, ensuring the appearance quality and performance of the conductive cloth.

[0017] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0018] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. 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.

[0020] See Figures 1 to 3 As shown, the structure of this utility model is as follows: a die-cutting blade for conductive cloth includes a blade holder 1, a blade template 2 mounted on the bottom of the blade holder 1, a cutting blade 3 at the bottom of the blade template 2, a receiving groove 4 between the blade holder 1 and the blade template 2, a heat-conducting block 5 within the receiving groove 4, an mounting groove 6 on the heat-conducting block 5, a heating element 7 within the mounting groove 6, and a heat insulation layer 8 between the blade holder 1 and the heat-conducting block 5. Specifically, the heating element 7 generates heat, which is conducted to the blade template 2 and the cutting blade 3 through the heat-conducting block 5, causing the temperature of the cutting blade 3 to rise. The heat insulation layer 8 between the blade holder 1 and the heat-conducting block 5 reduces heat transfer to the blade holder 1, ensuring that the heat is mainly concentrated in the blade template 2 and the cutting blade 3. When cutting conductive cloth, the high-temperature cutting blade 3 effectively reduces the difficulty of cutting the complex and dense fiber structure inside the conductive cloth, eliminating the need for large pressure and long cutting time, thus improving die-cutting efficiency, reducing production costs, and reducing wear on the cutting blade 3. At the same time, high-temperature cutting helps to cut the fibers neatly, avoids the fibers being pulled and forming burrs, and ensures the appearance quality and performance of the conductive cloth.

[0021] like Figure 2 As shown, the mounting groove 6 has an "S"-shaped structure. Specifically, the "S"-shaped mounting groove 6 can significantly increase the laying length of the heating element 7 within the limited space of the heat-conducting block 5, thereby increasing the contact area between the heating element 7 and the heat-conducting block 5. This allows the heat generated by the heating element 7 to be transferred to the heat-conducting block 5 more efficiently and widely, thus enabling the die template 2 and the cutting blade 3 to heat up quickly and evenly, improving the cutting ability of the conductive cloth fibers, solving the problem of difficult cutting at room temperature, and improving die-cutting efficiency. In terms of heat distribution, the "S"-shaped path allows heat to gradually diffuse along a tortuous route, avoiding local overheating or underheating, ensuring that the temperature of all parts of the cutting blade 3 is consistent, and guaranteeing the stability of cutting quality.

[0022] Furthermore, the heating element 7 is an electric heating tube. Specifically, the electric heating tube has high working efficiency, can quickly convert electrical energy into heat energy, and can rapidly heat up the cutting blade 3 to meet the high-temperature requirements of conductive fabric die-cutting, thereby improving cutting efficiency. Operation is simple; it only requires power. It has low thermal inertia, precise temperature control, and can ensure stable cutting quality. Moreover, its compact structure facilitates installation and maintenance. The cost is low, with both manufacturing and operating costs being relatively economical.

[0023] like Figure 2 , Figure 3 As shown, positioning grooves 9 are provided on both sides of the receiving groove 4, and positioning blocks 10 corresponding to the positioning grooves 9 are provided on the heat-conducting block 5. Specifically, the positioning blocks 10 cooperate with the positioning grooves 9 to ensure that the heat-conducting block 5 is accurately installed and positioned in the receiving groove 4, preventing displacement or shaking of the heat-conducting block 5 during operation. In this way, the heat generated by the heating element 7 can be stably and efficiently transferred to the die template 2 and the cutting blade 3 through the heat-conducting block 5, ensuring that the cutting blade 3 is heated evenly, thereby improving the quality and efficiency of conductive cloth die-cutting.

[0024] like Figure 2 As shown, the die-cutting template 2 has a mounting hole 11, and a temperature probe 12 is installed inside the mounting hole 11. Specifically, the temperature probe 12 can accurately monitor the temperature of the die-cutting template 2 in real time. During the die-cutting process of conductive cloth, the temperature of the die-cutting template 2 will change due to factors such as heating by the heating element and the cutting operation, and temperature has a significant impact on the cutting effect. By obtaining accurate temperature data through the temperature probe 12, the heating element 7 can be adjusted in a timely manner according to the actual situation to ensure that the die-cutting template 2 and the cutting blade 3 are at the optimal cutting temperature.

[0025] Furthermore, a thermally conductive medium is filled between the temperature probe 12 and the wall of the mounting hole 11. Specifically, the thermally conductive medium enhances heat transfer efficiency, allowing the heat from the die-cutting template 2 to be transferred to the temperature probe 12 more quickly and evenly. This allows the temperature probe 12 to sense the actual temperature of the die-cutting template 2 more promptly and accurately. During the conductive fabric die-cutting process, precise temperature monitoring helps to adjust the operating state of the heating element 7 in a timely manner based on temperature changes in the die-cutting template 2.

[0026] In practical use, during the die-cutting of conductive fabric, the heating element 7 is first activated. The heat generated by the heating element 7 is conducted to the die template 2 and the bottom cutting blade 3 through the heat-conducting block 5. Because a heat insulation layer 8 is provided between the die holder 1 and the heat-conducting block 5, heat transfer to the die holder 1 is effectively reduced, ensuring that the heat is mainly concentrated in the die template 2 and the cutting blade 3, allowing the cutting blade 3 to heat up quickly. Once the cutting blade 3 reaches a suitable working temperature, the die-cutting machine drives the die holder 1 to press down the cutting blade 3, cutting the conductive fabric. The high-temperature cutting blade 3 can easily cut through the complex and dense fibers inside the conductive fabric, improving cutting efficiency and quality. Throughout the process, the temperature of the cutting blade 3 is maintained stable by controlling the heating element 7, ensuring continuous and efficient completion of the conductive fabric die-cutting work.

[0027] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
