Description

Technical Field

[0001] This utility model relates to the field of heating plates for die-cutting machines, and in particular to a high-efficiency, energy-saving gradient temperature control heating plate for die-cutting machines. Background Technology

[0002] In the die-cutting industry, die-cutting machines use blades on a die-cutting plate to press and cut materials into shapes, and are widely used in packaging, printing, electronics, medical and other industries. However, existing die-cutting machines still have many technical defects when processing materials with different properties, resulting in prominent problems in processing quality, efficiency and equipment wear and tear.

[0003] Existing die-cutting machines often employ heating devices with either overall heating or simple localized heating structures, resulting in an inaccurate match between the heating area and the distribution of cutters on the cutting seat. For example, some machines attach the heating plate directly to the bottom of the cutting seat. Due to the diverse distribution of cutters on the cutting seat (such as irregular arrangements and varying densities), overall heating causes non-cutter areas to be heated simultaneously, leading to energy waste and potentially causing excessive softening or deformation of the material due to excessively high overall temperatures.

[0004] Meanwhile, traditional heating devices are mostly integrated structures, requiring complete replacement when heating elements or heat transfer components age or become damaged, resulting in high maintenance costs. Furthermore, when the cutting seat or cutter is replaced to adapt to different processing needs, the original heating system cannot match the new cutter distribution, necessitating a complete redesign of the heating structure. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-efficiency and energy-saving gradient temperature control heating plate for die-cutting machines.

[0006] The high-efficiency and energy-saving gradient temperature control heating plate for die-cutting machines provided by this utility model adopts the following technical solution:

[0007] A high-efficiency, energy-saving gradient temperature-controlled heating plate for a die-cutting machine includes a heating base, a heat-conducting mold frame, a fixing frame, and a lower mold base. The lower mold base is located above the heating base, and a receiving groove is provided at the bottom of the lower mold base. The fixing frame and the heat-conducting mold frame are both disposed within the lower mold base. The fixing frame is detachably connected to the lower mold base, and the heat-conducting mold frame is detachably connected to the fixing frame. A heat-conducting layer is disposed on the heat-conducting mold frame, the bottom of the heat-conducting layer is connected to the heat-conducting mold frame, and the top of the heat-conducting layer abuts against the inner wall of the receiving groove of the lower mold base. The shape of the heat-conducting layer is the same as the shape of the cutter of the die-cutting machine, and their upper and lower positions correspond. The bottom of the heat-conducting mold frame abuts against the heating base.

[0008] Optionally, the bottom of the heat-conducting mold frame is provided with a plurality of heat-conducting pillars, the bottom of the heat-conducting pillars being flush with the bottom of the lower mold base, and the bottom of the heat-conducting pillars abutting against the heating base.

[0009] Optionally, springs and connecting plates are provided on both sides of the fixing frame, with one end of the spring fixed to the side wall of the fixing frame and the other end of the spring fixed to the connecting plate.

[0010] Optionally, the top of the connecting plate is chamfered.

[0011] Optionally, a handle is provided on the side wall of the lower mold base.

[0012] Optionally, the thermally conductive layer is made of graphene composite material, and the thermally conductive layer is bonded and fixed to the thermally conductive mold frame with thermally conductive adhesive.

[0013] Optionally, the heating base is provided with several independently controlled heating units, the heating units are positioned one-to-one with the heat-conducting columns, and the heating power of each heating unit can be adjusted independently.

[0014] In summary, this utility model has at least one of the following beneficial technical effects:

[0015] 1. When the die-cutting machine is replaced with a cutter of a different shape, only the heat-conducting mold frame and heat-conducting layer that match the shape of the new cutter need to be replaced. The shape of the heat-conducting layer is the same as the shape of the cutter and the upper and lower positions correspond. Structurally, this ensures that the heating area and the cutting area overlap, preventing energy waste caused by overall heating and avoiding excessive softening or deformation of the material due to excessive overall temperature.

[0016] 2. Local heating softens the material only at the point of contact with the blade, while the non-contact areas retain their original physical properties. This reduces the problem of increased ductility caused by overall material heating. Local heating softens the area of ​​the material in contact with the blade, reducing cutting resistance, while the remaining areas remain rigid, avoiding aluminum foil wrinkles caused by overall softening and improving the smoothness of the cutting edge.

[0017] 3. The bottom of the heat-conducting mold base is provided with several heat-conducting pillars. The bottom of the heat-conducting pillars is flush with the bottom of the lower mold base. The bottom of the heat-conducting pillars abuts against the heating base. The heat-conducting pillars are designed as directional channels for heat transfer, which can strengthen the heat conduction path and improve heat transfer efficiency.

[0018] 4. Springs and connecting plates are installed on both sides of the fixed frame. The connecting plates on both sides can be pressed into the receiving groove of the lower mold base. Under the action of the spring, the fixed frame and the lower mold base are relatively fixed. When disassembling, simply pull the mold frame out of the fixed frame to release the lateral constraint on the heat conduction mold frame. No tools are required throughout the process, which greatly simplifies the replacement operation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Furthermore, "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] This utility model discloses a high-efficiency, energy-saving gradient temperature-controlled heating plate for a die-cutting machine. (Refer to...) Figure 1-4 A high-efficiency and energy-saving gradient temperature control heating plate for die-cutting machines includes a heating base 2, a heat-conducting mold frame 3, a fixing frame 4, and a lower mold base 5;

[0028] The heating base 2 and the lower die base 5 are both set on the connecting seat 1 of the die-cutting machine. The lower die base 5 is detachably connected to the connecting seat 1 of the die-cutting machine. A slot is provided on one side of the connecting seat 1. The lower die base 5 can slide on the connecting seat 1 through the slot, so as to disassemble or assemble the lower die base 5.

[0029] The lower mold base 5 is located above the heating base 2. The bottom of the lower mold base 5 is provided with a receiving groove 51. The fixing frame 4 and the heat-conducting mold frame 3 are both set inside the lower mold base 5. The fixing frame 4 is detachably connected to the lower mold base 5. The heat-conducting mold frame 3 is detachably connected to the fixing frame 4. A heat-conducting layer 6 is provided on the heat-conducting mold frame 3. The bottom of the heat-conducting layer 6 is connected to the heat-conducting mold frame 3. The top of the heat-conducting layer 6 abuts against the inner wall of the receiving groove 51 of the lower mold base 5. The shape of the heat-conducting layer 6 is the same as the shape of the cutting blade of the die-cutting machine, and the upper and lower positions are corresponding. The bottom of the heat-conducting mold frame 3 abuts against the heating base 2.

[0030] The heating base 2 serves as the core heat source. When powered on, it generates heat, which is directly transferred to the heat-conducting mold frame 3 that it contacts. The heat from the heat-conducting mold frame 3 is then transferred to the top heat-conducting layer 6. Since the shape of the heat-conducting layer 6 is exactly the same as that of the cutter and their vertical positions correspond, the heat is transferred vertically upward to the inner wall of the receiving groove 51 of the lower mold base 5 by replicating the contour path of the cutter through the heat-conducting layer 6. With this design, when the die-cutting machine changes to a different shape of cutter (such as changing from a rectangular cutter to an irregular cutter, or from a dense cutter to a sparse cutter), only the heat-conducting mold frame 3 and the heat-conducting layer 6 that match the shape of the new cutter need to be replaced accordingly. The shape of the heat-conducting layer 6 is the same as that of the cutter and their vertical positions correspond, which structurally ensures that the heating area and the cutting area overlap, preventing energy waste caused by overall heating and avoiding excessive softening or deformation of the material due to excessive overall temperature.

[0031] This localized heating softens the material only at the point of contact with the blade, while the non-contact areas retain their original physical properties. This reduces the problem of increased ductility caused by overall material heating. For example, when cutting thin aluminum foil, localized heating softens the area where the aluminum foil contacts the blade, reducing cutting resistance, while the remaining areas remain rigid, avoiding wrinkles in the aluminum foil caused by overall softening and improving the smoothness of the cut edges.

[0032] In this invention, a silicone thermal conductive layer 6 can be designed on the top of the thermal conductive layer 6. The flexibility of the silicone thermal conductive layer 6 can eliminate the tiny gap between the thermal conductive mold frame 3 and the lower mold base 5, ensuring the continuity of heat transfer.

[0033] The bottom of the heat-conducting mold frame 3 is provided with several heat-conducting pillars 7. The bottom of the heat-conducting pillars 7 is flush with the bottom of the lower mold base 5. The bottom of the heat-conducting pillars 7 abuts against the heating base 2. The heat-conducting pillars 7 are designed as directional channels for heat transfer, which can strengthen the heat conduction path and improve the heat transfer efficiency.

[0034] Springs 8 and connecting plates 9 are provided on both sides of the fixed frame 4. One end of the spring 8 is fixed to the side wall of the fixed frame 4, and the other end of the spring 8 is fixed to the connecting plate 9. With this design, the connecting plates 9 on both sides can be pressed into the receiving groove 51 of the lower mold base 5. Under the action of the spring 8, the fixed frame 4 and the lower mold base 5 are relatively fixed. When disassembling, the mold frame can be directly pulled out from the fixed frame 4 to release the lateral constraint on the heat-conducting mold frame 3. No tools are required throughout the process, which greatly simplifies the replacement operation.

[0035] The top of the connecting plate 9 is provided with a chamfer 10. The chamfer 10 makes it easier to insert the connecting plates 9 on both sides of the fixing frame 4 into the receiving groove 51 of the lower mold base 5. The side wall of the lower mold base 5 is provided with a handle 11. The operator can easily slide the lower mold base 5 out along the groove by holding the handle 11.

[0036] In this invention, the thermally conductive layer 6 is made of graphene composite material, and the thermally conductive layer 6 and the thermally conductive mold 3 are bonded and fixed together by thermally conductive adhesive. The use of thermally conductive adhesive to fix the thermally conductive layer 6 and the thermally conductive mold 3 has the dual functions of fixing and thermal conduction compared with mechanical fixing or ordinary glue. The thermally conductive adhesive has fluidity before curing and can fill the tiny gaps between the thermally conductive layer 6 and the thermally conductive mold 3. After curing, it forms a tight integrated structure, avoiding the increase in thermal resistance caused by air gaps.

[0037] The heating base 2 is equipped with several independently controlled heating units. The heating units correspond one-to-one with the positions of the heat-conducting columns 7, and the heating power of each heating unit can be adjusted independently.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
