DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and implementation methods. It is understood that the specific implementation methods described here are only used to explain the relevant content, rather than to limit the utility model.

[0038] It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the drawings.

[0039] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] In the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] Due to the iteration of new products, the coating on the surface of the product has been cancelled. When the left and right sides of the product are embossed, the embossing contact surface will be damaged. In practice, the damage rate is as high as 80%, so it is difficult to guarantee the quality of the product.

[0042] In order to solve the problem of product damage, it has been found through research that paper can increase its toughness after heating, thus avoiding damage during the embossing process. The reasons are:

[0043] Embodiment 1

[0044] First, paper is mainly composed of fibers, which are relatively rigid at room temperature and easily break under external forces. When paper is heated, the moisture between the fibers increases their mobility, making the fibers softer and more plastic. The softness allows the paper to better adapt to changes in shape when pressure is applied, rather than breaking directly.

[0045] Second, heating can temporarily break certain chemical bonds in the paper, such as hydrogen bonds, between cellulose molecules, giving the fibers more room to move on a microscopic level, increasing overall flexibility. When the paper cools, these chemical bonds usually reform, but the shape from processing is maintained.

[0046] Finally, mechanical processing will cause internal stress in the paper. If it is not properly handled, it may cause the paper to break during the embossing process. During the heating process, the stress inside the paper can be released to a certain extent, thereby relaxing the processing stress and making the paper more stable during the processing.

[0047] Taking all the above factors into consideration, proper heating treatment of paper can effectively improve its toughness and ductility during physical processing and reduce the risk of damage during embossing.

[0048] Because, if Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a embossing mold with a heating function, including: an embossing base plate 1, an upper fixing plate 2, a middle fixing plate and a heating component.

[0049] The embossing bottom plate 1 is horizontally arranged, and a lower embedding groove is arranged on the upper side of the embossing bottom plate 1, and an embossing female mold 3 is arranged in the lower embedding groove; the upper fixed plate 2 is horizontally arranged above the embossing bottom plate 1, and a driving component is arranged on the upper fixed plate 2; the middle fixed plate is horizontally arranged between the upper fixed plate 2 and the embossing bottom plate 1, and an upper embedding groove corresponding to the lower embedding groove is arranged on the middle fixed plate, and an embossing male mold 4 corresponding to the embossing female mold 3 is arranged in the upper embedding groove, and the middle fixed plate is connected to the driving end of the driving component, and the driving component drives the middle fixed plate to move up and down; the heating end of the heating component is arranged in the middle fixed plate, and the heating component heats the middle fixed plate and transfers heat to the embossing male mold 4, and heats up the embossing male mold 4. A pad is arranged on the lower side of the embossing bottom plate 1.

[0050] Embossing is a cold or hot pressing process used to form raised patterns or text on materials. The embossing female mold 3 and the embossing male mold 4 are the parts that form the specific shape of the product. The embossing male mold 4 is driven by the driving component to move toward the embossing female mold 3, and the paper is placed between the embossing male mold 4 and the embossing female mold 3 to achieve the embossing operation on the paper.

[0051] When the embossing die starts to work, the driving component (such as a cylinder or a motor) is started to drive the middle fixed plate to move up and down in the vertical direction. During the movement, the embossing male die 4 on the middle fixed plate cooperates with the embossing female die 3 on the bottom plate to perform embossing processing on the material (such as paper) placed between the two.

[0052] At the same time, the heating assembly heats the central fixing plate during the whole process. Due to heat conduction, the temperature of the embossing male mold 4 will also rise. This heating can increase the temperature of the processed material, thereby increasing its flexibility and ductility and reducing the probability of breakage during the embossing process.

[0053] The work process includes:

[0054] Heating stage: before starting embossing, the heating assembly preheats the middle fixing plate and the embossing male mold 4 thereon to a set temperature.

[0055] Embossing processing stage: the driving component is activated, and the middle fixed plate drives the embossing male mold 4 to move downward, and combines with the female mold to shape the material between the female mold and the male mold.

[0056] Material forming: The heated male mold contacts the material, and the material is pressed into a specific shape while being heated. The heat helps shape the material and reduces breakage during forming.

[0057] Reset stage: After the embossing process is completed, the driving assembly works in reverse to return the middle fixing plate and the embossing male mold 4 to their original positions, preparing for the next process.

[0058] Embodiment 2

[0059] The heating assembly includes: a temperature control meter and a heating rod 5. A plurality of heating holes are arranged on the middle fixed plate. The heating rod 5 is fixedly arranged in the heating holes and conducts heat with the middle fixed plate. The control end of the heating rod 5 is electrically connected to the temperature control meter.

[0060] When in working state, the temperature of the embossing male mold 4 is 65°C±5°C.

[0061] The heating of the heating rod 5 is controlled by a temperature control meter. The temperature generated by the heating rod 5 is transferred to the middle fixing plate by heat conduction, and then transferred to the embossing mold 4 through the middle fixing plate. Therefore, the middle fixing plate needs to have thermal conductivity.

[0062] Setting the temperature of the embossing mold 4 to 65°C ± 5°C is based on a comprehensive consideration of material properties and processing effects. Paper and many similar materials are susceptible to thermal damage at excessively high temperatures, such as discoloration, strength loss, or scorching. Controlling the temperature within the range of 65°C ± 5°C can effectively avoid these negative effects, while sufficient temperature can improve processing effects.

[0063] The temperature points can be selected as 60℃, 61℃, 62℃, 63℃, 64℃, 65℃, 66℃, 67℃, 68℃, 69℃, 70℃ and other temperatures to obtain fluctuations within the range of 60℃ - 70℃.

[0064] In addition, in combination with the structure in the third embodiment, the number of the heating rods 5 in the left middle fixing plate 8 is at least two, and they are respectively arranged on both sides of the embossing male mold 4;

[0065] The number of the heating rods 5 in the right middle fixing plate 9 is at least two, and they are respectively arranged on both sides of the embossing male mold 4 .

[0066] By arranging the heating rods 5 on both sides of the embossing mold 4, the embossing mold 4 can be heated better.

[0075] Before the processing begins, the operator sets the temperature of the left temperature control meter 6 and the right temperature control meter 7 to ensure that the heating rod 5 reaches the required processing temperature. The left middle fixing plate 8 and the right middle fixing plate 9 are preheated to the set temperature respectively.

[0076] The driving assembly (the left driving cylinder 12 and the right driving cylinder 13) is started to drive the left and right middle fixing plates to move up and down along the guide pillars respectively. The moving middle fixing plate drives the embossing male die 4 in the upper embedded groove to press downward against the embossing female die 3 on the bottom plate to process the material placed between the two.
