Description

Technical Field

[0001] This utility model relates to the technical field of hot stamping machines, and in particular to a temperature zone control device for hot stamping machine printing plates. Background Technology

[0002] In modern printing processes, hot stamping technology, with its unique metallic texture and decorative effect, is widely used in high-end packaging, bookbinding, and trademark production. The hot stamping machine, as the core equipment, primarily uses a heated printing plate to thermally bond the metal foil to the substrate, thus completing the hot stamping process. In this process, the uniformity of the printing plate temperature plays a decisive role, directly affecting not only the adhesion between the metal foil and the substrate but also the clarity, gloss, and overall quality of the hot stamping pattern. If the printing plate temperature becomes excessively hot or cold in certain areas, it can lead to uneven color, blurred patterns, and metal foil detachment, severely impacting the product's aesthetics and quality. Therefore, a temperature zone control device for the hot stamping machine printing plate is particularly needed.

[0003] However, existing hot stamping machines mostly use a whole-plate heating method to control the temperature of the printing plate. Heating the entire printing plate with a single heat source will result in temperature deviation between the edge and the center, causing the hot stamping pattern to have dull color at the edge, burn through the center, or be poorly stamped overall. Furthermore, it is impossible to adjust the temperature individually according to the hot stamping requirements of different pattern areas on the printing plate, and it cannot meet the hot stamping needs of various printing plates.

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.

[0019] Please see Figure 1-4This utility model provides a technical solution: a temperature zone control device for hot stamping machine printing plates, including a mounting frame 1, a fixing plate 2 fixedly mounted on the top of the mounting frame 1, a through hole 3 opened on the top of the fixing plate 2, a printing plate placement platform 4 fixedly mounted on the top of the fixing plate 2, a conduction hole 5 opened on the top of the printing plate placement platform 4, a support column 6 fixedly mounted on the top of the printing plate placement platform 4, an extension plate 7 fixedly mounted on the outer side of the support column 6, a temperature sensor 8 fixedly mounted on the top of the extension plate 7, and a top... Heating assembly 9, and a partitioned heating assembly 10 is provided on the top of the mounting bracket 1; the partitioned heating assembly 10 includes a mounting base 1001, which is mounted on the mounting bracket 1. A motor 1002 is fixedly mounted on the top of the mounting base 1001, and a transmission screw 1003 is fixedly mounted on the output end of the motor 1002. A slide rail 1004 is fixedly mounted on the top of the mounting bracket 1, and a movable seat 1005 is threadedly connected to the outer side of the transmission screw 1003. The top of the movable seat 1005 is fixedly mounted on... A mounting base 1006 is provided, and a motor 1007 is fixedly mounted on the top of the mounting base 1006. A transmission screw 1008 is fixedly mounted on the output end of the motor 1007. A partition heating box 1009 is threadedly connected to the outer side of the transmission screw 1008. A heat dissipation hole 1010 is provided on the outer side of the partition heating box 1009. A partition plate 1011 is fixedly mounted on the top of the partition heating box 1009. A heating hole 1012 is provided on the top of the partition plate 1011. The partition heating assembly 1009 is thus provided. Through the horizontal and vertical linkage of motor 1002, transmission screw 1003 and motor 2007, transmission screw 2 1008, the partition heating box 1009 is driven to move precisely on the slide rail 1004. With the cooperation of multiple sets of equally distributed partition plates 1011 and heating holes 2 1012, fixed-point heating of any area on the bottom of the printing plate can be achieved. The heat dissipation holes 1010 opened on the outside of the partition heating box 1009 can dissipate the heat inside the box in time, avoiding performance degradation or damage of the heating components due to overheating, without the need to replace the entire heating module.

[0020] Furthermore, the top heating assembly 9 includes an electric cylinder 901, which is mounted on the extension plate 7. A telescopic rod 902 is fixedly mounted on the movable end of the electric cylinder 901. A connecting plate 903 is fixedly mounted on the end of the telescopic rod 902 away from the electric cylinder 901. The bottom of the connecting plate 903 has a mounting groove 904, and the outer side of the connecting plate 903 has a first mortise 905. A mounting post 906 is provided at the bottom of the connecting plate 903, and the outer side of the mounting post 906 has a second mortise 907. A snap-fit ​​post 908 is provided on the outer side of the connecting plate 903, and a fixing rod 909 is provided on the outer side of the snap-fit ​​post 908. A snap-fit ​​groove 910 is provided on the outer side of the fixing rod 909. The bottom of the mounting post 906 is fixed... The top heating seat 911 is equipped with a heating hole 912 at its bottom. Through the top heating component 9, the electric cylinder 901 drives the telescopic rod 902 to move the top heating seat 911 up and down. The heating distance can be adjusted according to the thickness of the printing plate. The heating hole 912 at the bottom can specifically heat a specific area on the surface of the printing plate. Multiple sets of mounting slots 904 are used to fit the mounting posts 906. With the engagement of tenon slot 905, tenon slot 907 and snap-fit ​​post 908, and the auxiliary fixation of fixing rod 909 and snap-fit ​​slot 910, the top heating seat 911 can be quickly disassembled and replaced. It is compatible with heating seats of different sizes and heating hole layouts to meet the hot stamping needs of various printing plates.

[0021] Furthermore, the through hole 3 is adapted to the printing plate placement stage 4, and multiple sets of conductive holes 5 are provided. These multiple sets of conductive holes 5 are located on the top of the printing plate placement stage 4 and are equidistantly distributed. By setting multiple sets of conductive holes 5, heat is prevented from accumulating inside the stage and forming local high temperatures, ensuring that the bottom of the printing plate is heated evenly. This allows the sensor to indirectly sense the temperature of the bottom of the printing plate, complementing the directly detected surface temperature of the printing plate, reducing temperature detection blind spots, making temperature control data more comprehensive, and further improving the accuracy of temperature control.

[0022] Furthermore, the mounting slots 904 and mounting posts 906 are each provided with four identical sets, and the four sets of mounting slots 904 and mounting posts 906 are all compatible. By providing four sets of mounting slots 904 and mounting posts 906, the heating seat is prevented from tilting due to uneven force on one side, ensuring that the distance between the heating hole 912 and the printing plate surface is consistent, preventing differences in hot stamping effect caused by local heating distance deviation. The multiple sets of compatible installations also improve the fault tolerance of the structure. Even if one set of installation structure experiences slight wear, the other three sets can still maintain a stable connection, extending the overall service life of the top heating component 9.

[0023] Furthermore, the hole diameter of tenon 1 905 is the same as that of tenon 2 907. Both tenon 1 905 and tenon 2 907 are adapted to the snap-fit ​​post 908. By setting tenon 1 905 and tenon 2 907, the connecting plate 903 and the mounting post 906 can be quickly aligned, avoiding jamming or misalignment caused by hole mismatch during installation, shortening the disassembly and assembly time, limiting the relative movement of the connecting plate 903 and the mounting post 906 in the horizontal direction, preventing them from loosening due to vibration during heating, ensuring the stable position of the top heating seat 911, and accurately aligning the heating area with the target area of ​​the printing plate.

[0024] Furthermore, two identical sets of fixing rods 909 and snap-fit ​​grooves 910 are provided, and the two sets of fixing rods 909 and snap-fit ​​grooves 910 are symmetrically distributed about the vertical center line of the connecting plate 903. The snap-fit ​​grooves 910 are adapted to the snap-fit ​​posts 908. By setting two sets of fixing rods 909 and snap-fit ​​grooves 910, the symmetrically distributed fixing rods 909 and snap-fit ​​grooves 910 can form auxiliary fixation for the snap-fit ​​posts 908 from both sides of the connecting plate 903, further enhancing the connection strength between the connecting plate 903 and the mounting post 906, avoiding structural instability caused by fixing in one direction. At the same time, the two sets of fixing structures facilitate simultaneous operation by operators from both sides, improving the convenience of disassembly and assembly. Moreover, the symmetrical design ensures balanced force distribution and reduces damage to components caused by local stress concentration.

[0025] Furthermore, the slide rail 1004 and the moving seat 1005 are slidably connected, the first transmission screw 1003 and the second transmission screw 1008 are in the horizontal and vertical directions, and the partition plate 1011 and the second heating hole 1012 are provided in multiple sets. The multiple sets of partition plates 1011 and the second heating hole 1012 are located on the top of the partition heating box 1009 and are equidistantly distributed. By setting the first transmission screw 1003 and the second transmission screw 1008 in the horizontal and vertical directions, the horizontal and vertical linkage transmission structure allows the partition heating box 1009 to move arbitrarily in a two-dimensional plane, which can accurately cover every area of ​​the bottom of the printing plate and meet the heating needs of different areas of complex patterns. With the multiple sets of equidistantly distributed partition plates 1011 and the second heating hole 1012, the bottom of the printing plate can be divided into multiple independent heating units to achieve on-demand heating, which not only reduces energy waste, but also allows for precise temperature control for different areas, further improving the flexibility of partition temperature control.

[0026] Working principle: First, the operator places the mounting frame 1 flat on a horizontal operating platform and checks whether the frame structure is stable. The electric cylinder 901 is fixedly installed on the outside of the extension plate 7, with the movable end of the electric cylinder 901 facing downwards. One end of the telescopic rod 902 is fixedly connected to the movable end of the electric cylinder 901, and the other end is fastened to the connecting plate 903 with bolts. Four sets of mounting slots 904 are opened at the bottom of the connecting plate 903. The mounting posts 906 are correspondingly embedded into the mounting slots 904, ensuring a tight fit between the mounting posts 906 and the mounting slots 904. A tenon groove 905 is opened on the outside of the connecting plate 903, and a second tenon groove 907 is correspondingly opened on the outside of the mounting posts 906. The snap-fit ​​post 908 is simultaneously embedded into the first tenon groove 905 and the tenon groove 907. Slot 907 provides initial fixation between the connecting plate 903 and the mounting post 906. Two sets of fixing rods 909 are symmetrically installed on the outer side of the connecting plate 903. A snap-fit ​​groove 910 is opened on the outer side of the fixing rod 909 to fit the snap-fit ​​post 908, thus providing secondary fixation and enhancing connection stability. Finally, a top heating seat 911 is fixedly installed at the bottom of the mounting post 906, ensuring that the heating hole 912 at the bottom of the top heating seat 911 faces the printing plate placement stage 4, completing the overall assembly of the top heating assembly 9. A mounting base 1001 is fixedly installed on the top of the mounting frame 1, and a motor 10 is bolted to the top of the mounting base 1001. 02. Connect the output end of the first transmission screw 1003 and the first motor 1002 via a coupling. Fix the slide rail 1004 on the top of the mounting bracket 1, parallel to the direction of the first transmission screw 1003. Thread the inner side of the movable seat 1005 to the first transmission screw 1003, and slidably connect the outer side to the slide rail 1004, ensuring the movable seat 1005 can move smoothly along the slide rail 1004. Fix the second mounting base 1006 on the top of the movable seat 1005. Fix the second motor 1007 on the top of the second mounting base 1006. Connect the output end of the second motor 1007 to the second transmission screw 1008 via a coupling. The second transmission screw 1008 and the first transmission screw 1003 are perpendicular in both directions. The inner side of the partition heating box 1009 is threaded to the second transmission screw 1008 to ensure that the partition heating box 1009 can move horizontally and vertically under the drive of the second transmission screw 1008. Heat dissipation holes 1010 are opened on the outer side of the partition heating box 1009. Multiple sets of equally spaced partition plates 1011 are fixedly installed on the top. Heating holes 1012 are opened on the top of the partition plates 1011. The assembly of the partition heating component 10 is completed. After all components are installed, check whether the connection parts are firm and whether the wiring connection is correct. Power on the equipment and test whether the electric cylinder 901 of the top heating component 9 can drive the top heating seat 911 to move smoothly up and down, and whether the first heating hole 912 can heat normally.Test whether motor 1002 and motor 1007 of the zone heating assembly 10 can drive the zone heating box 1009 to move accurately in the horizontal and vertical directions, whether heating hole 1012 heats normally, and whether heat dissipation hole 1010 dissipates heat smoothly. Collect the temperature of different areas of the printing plate placement stage 4 through temperature sensor 8, and observe whether precise temperature control of each zone can be achieved. If there is a deviation, adjust the power of the heating assembly or the position of the sensor until the overall function of the equipment meets the design requirements.
