Description

Technical Field

[0001] This utility model relates to an embossing device for processing packaging boxes, and in particular to an embossing device for processing packaging boxes, belonging to the field of mechanical processing technology. Background Technology

[0002] Embossing technology involves pressing patterns or textures onto material surfaces using molds and pressure, and is widely used in industries such as packaging, electronics, automotive, and construction. Its core technologies include mold design, precise pressure control, heating and cooling systems, and automation control. Embossing machines typically use molds to press specific patterns or textures onto material surfaces. Common embossing methods include hot pressing, cold pressing, and ultra-high pressure embossing. Among them, hot pressing embossing technology mainly involves heating the mold or material surface, causing the material to soften at high temperatures. It has advantages such as improving material formability, fine embossing effect, reducing material deformation, increasing production efficiency, and strong adaptability. Therefore, hot pressing is suitable for a variety of materials, such as paper, plastics, and leather, and is especially widely used in the packaging industry and high-end product surface processing.

[0003] Existing embossing equipment for packaging boxes typically fixes the template to a base plate and heats it through the base plate. However, whether heating is done via heat pipes or heat transfer oil, the heating device on the base plate needs to be made as large as possible to accommodate changes in the template size. This leads to reduced energy utilization, decreased heating efficiency, and significantly increased production costs.

[0004] Therefore, it is urgent to improve the embossing equipment for processing packaging boxes in order to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an embossing device for processing packaging boxes. This device opens a heat-conducting cavity connected to a heat pump on the base plate, allowing the heat-conducting liquid to circulate within the base plate, thereby keeping the temperature of the printing plate fixed on the base plate within a suitable range. When in use, the position of the push plate is first adjusted so that the area through which the heat-conducting oil flows matches the size of the printing plate, reducing heat loss.

[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a housing and a hydraulic press. A base plate is connected to the housing. The base plate has several grooves. A sealing plate is connected to the side of the base plate near the grooves. Two push plates are symmetrically arranged on both sides of the sealing plate. The push plates have protrusions that are slidably connected to the grooves and are the same number as the grooves on the side near the grooves. A cover plate is connected to the side of the push plates near the sealing plate. Several independent and sealed heat-conducting cavities are formed between the sealing plate, the several protrusions, the cover plate, and the several grooves. Several independent heat-conducting channels are opened on both push plates. Two adjacent heat-conducting cavities are connected through the heat-conducting channels.

[0007] Preferably, the raised plate has a groove, and a sealing strip is fixedly connected to the groove, with the sealing strip in close contact with the inner wall of the groove.

[0008] Preferably, a bidirectional threaded rod is rotatably connected to the housing, and the two ends of the bidirectional threaded rod are respectively threaded to the two push plates.

[0009] Preferably, the housing is equipped with a heat pump, and the input end and output end of the heat pump are respectively connected to an input heat pipe and an output heat pipe, and the input end and output end of the input heat pipe and the output heat pipe both extend into the interior of the heat-conducting cavity.

[0010] Preferably, the cover plate has protrusions on both sides, and the groove has an inner recess that matches the protrusions. A groove is formed on the end of the cover plate away from the push plate, and a sealing ring is fixedly connected in the groove. The sealing ring is in close contact with the wall of the sealing plate.

[0011] Preferably, each of the two push plates is provided with a heat insulation plate on the side near the sealing plate, and the sealing plate has a cavity for accommodating the heat insulation plate.

[0012] Preferably, the hydraulic press is located at the top of the housing, and a pressure plate parallel to the base plate is connected to the output end of the hydraulic press.

[0013] This utility model has at least the following beneficial effects: 1. By creating grooves in the base plate and connecting them to a heat pump via heat pipes, the heat transfer fluid circulates within the base plate, thus maintaining the temperature of the printing plate fixed on the base plate within a suitable range. Furthermore, push plates are symmetrically positioned at both ends of the grooves. During use, the position of the push plates is adjusted according to the size of the printing plate, thereby ensuring that the area through which the heat transfer oil flows matches the size of the printing plate as closely as possible, reducing heat loss.

[0016] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] like Figures 1-4 As shown, the embossing equipment for processing packaging boxes provided in this embodiment includes a housing 1 and a hydraulic press 2. A base plate 3 is connected to the housing 1. The base plate 3 has several grooves 4. A sealing plate 5 is connected to the side of the base plate 3 near the grooves 4. Two push plates 6 are symmetrically arranged on both sides of the sealing plate 5. The side of the push plate 6 near the grooves 4 has protrusions 7 that are slidably connected to the grooves 4 and are the same number as the grooves 4. A cover plate 8 is connected to the side of the push plate 6 near the sealing plate 5. The sealing plate 5, the several protrusions 7, and the cover plate 8 are connected to the several grooves 4. Several independent and sealed heat-conducting cavities 9 are formed between the grooves 4. Several independent heat-conducting channels 10 are opened on both push plates 6. Two adjacent heat-conducting cavities 9 are connected through the heat-conducting channels 10. The heat-conducting channels 10 on the two push plates 6 are arranged in a cross manner, so that the heat-conducting oil flows in one direction and avoids the flow path of the heat-conducting oil being disordered. The width of the sealing plate 5 is sufficient to cover all the grooves 4, and the sealing plate 5 is located in the middle of the floor. The two sides of the sealing plate 5 are flat and flush with the sides of the push plate 6, so that when the push plate 6 moves to the sealing plate 5, it can be in close contact with the sealing plate 5.

[0018] A groove 11 is provided on the raised plate 7. The groove 11 is set along the contact surface between the raised plate 7 and the groove 4, and the depth and width of the groove 11 are equal everywhere. A sealing strip 12 is fixedly connected in the groove 11. The sealing strip 12 is in close contact with the inner wall of the groove 4. When the heat transfer fluid flows in the heat transfer cavity 9, the liquid pressure forces the sealing strip 12 to block the tiny gap between the groove and the raised plate 7. This sealing structure refers to the O-ring sealing technology in the prior art.

[0019] A bidirectional threaded rod 13 is rotatably connected to the housing 1, and the two ends of the bidirectional threaded rod 13 are respectively threaded to two push plates 6. When the bidirectional threaded rod 13 is rotated, the two push plates 6 move relative to each other. The protruding plate 7 on the push plate 6 moves with the push plate 6 in the groove 4. When the push plates 6 move away from each other, the length of the heat conduction cavity 9 increases and the heat conduction area increases. When the push plates 6 move closer to each other, the length of the heat conduction cavity 9 decreases and the heat conduction area decreases.

[0020] A heat pump 14 is provided on the housing 1. The input end and output end of the heat pump 14 are respectively connected to the input heat pipe 15 and the output heat pipe 16. The input end and the output end of the input heat pipe 15 and the output heat pipe 16 extend into the heat conduction cavity 9. The heat conduction liquid is heated in the heat pump 14 and then flows out of the heat pump 14, enters the input heat pipe 15 and enters the heat conduction cavity 9. The heat conduction liquid enters the adjacent heat conduction cavity 9 through the heat conduction channel 10, and after passing through all the heat conduction cavities 9, it enters the output heat conduction pipe 16 and flows into the heat pump 14, forming a cycle.

[0021] The cover plate 88 has protrusions 17 on both sides, and the groove 4 has concave portions 18 that are adapted to the protrusions 17. The protrusions 17 on the cover plate 8 and the concave portions 18 on the groove 4 form a labyrinth seal structure to prevent the heat transfer fluid from seeping out from the gap between the groove 4 and the cover plate 8. A groove 19 is provided on the end of the cover plate 8 away from the push plate 6. A sealing ring 20 is fixedly connected in the groove 19. The sealing ring 20 is in close contact with the wall of the sealing plate 5 to prevent the heat transfer fluid from seeping out from the gap between the sealing plate 5 and the cover plate 8.

[0022] Each of the two push plates 6 is provided with a heat insulation plate 21 on the side near the sealing plate 5. The sealing plate 5 has a cavity for accommodating the heat insulation plate 21. The sealing plate 5 moves with the push plates 6. When the push plates 6 approach each other, the sealing plate 5 will enter the cavity opened on the sealing plate 5.

[0023] The hydraulic press 2 is located on the top of the casing 1. A pressure plate 22 parallel to the base plate 3 is connected to the output end of the hydraulic press 2. The output end of the hydraulic press 2 is a metal column. A template is fixed on the base plate 3, and the paper material is placed between the template and the pressure plate 22. When the device is running, the hydraulic press 2 drives the metal column to extend. The pressure plate 22 will move closer to the template as the metal column moves. When it moves to the set position, the pressure plate 22 presses the paper material tightly on the template. At this time, the heat pump 14 delivers heat transfer oil with a certain temperature to the heat transfer chamber 9. The heat is transferred from the heat transfer oil through the base plate 3 to the template. The template then heats the paper material pressed on it, making the raw material easier to process.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments.
