[0025] Example

[0026] like Figure 1-3 As shown, this embodiment provides a nano-ceramic heating mold for pulp molding, including a mold 1, a ceramic heating plate, an insulation layer 4, a vacuum layer 5 and a mold frame 6 arranged in sequence from top to bottom, wherein the mold 1, the ceramic heating plate, the insulation layer 4, and the vacuum layer 5 are aligned and stacked together, and then fixed on the mold frame 6 by four fixing screws 7 on all sides.

[0027] Specifically, the ceramic heating plate includes a substrate 2 and a nano-heating ceramic 3. The substrate 2 is provided with at least one mounting groove 21 on one side close to the mold 1. One end of the mounting groove 21 penetrates the substrate 2 to form an insertion port. One end of the nano-heating ceramic 3 is inserted into the mounting groove 21 through the insertion port of the mounting groove 21. A wiring terminal 31 is provided at one end of the nano-heating ceramic 3. The wiring terminal 31 extends to the outside of the mounting groove 21. The wiring terminal 31 is used to connect a wire for electrical heating.

[0028] In this embodiment, there are three mounting grooves 21, and the substrate 2 is provided with a plurality of through holes located at intervals between the three mounting grooves 21. The through holes are respectively connected to the mold 1 and the vacuum chamber 51. The vacuum chamber 51 is connected through the through holes, so that the vacuum chamber 51 can absorb moisture from the mold 1, thereby accelerating the drying and molding process of the product.

[0029] Furthermore, a limiting screw 11 is detachably connected to a position on the side of the mold 1 corresponding to the insertion port. Specifically, a threaded sleeve is provided on the side of the mold 1, and the limiting screw 11 is bolted in the threaded sleeve. The bottom of the limiting screw 11 passes through the threaded sleeve and extends to the side of the nano-heating ceramic 3, and is set against the nano-heating ceramic 3. The nano-heating ceramic 3 is limited by the limiting screw 11 to prevent it from loosening and disengaging from the mounting groove 21.

[0030] Furthermore, a plurality of spring mounting grooves 22 are provided in the mounting groove 21 at the bottom of the nano-heating ceramic 3, and a spring 23 is embedded in the spring mounting groove 22. The top of the spring 23 is arranged to resist the nano-heating ceramic 3. Through the elastic force of the spring 23, the nano-heating ceramic 3 is pushed toward the mold 1, so that the nano-heating ceramic 3 is tightly attached to the mold 1, thereby improving the heating effect.

[0031] Specifically, a vacuum cavity 51 is provided inside the vacuum layer 5, one end of the vacuum cavity 51 is connected to the mold 1, and the other end is provided through the mold frame 6 and connected to a vacuum device. The mold 1 is provided with a plurality of densely distributed fine holes, and the wet embryo is placed on the mold 1. The moisture of the wet embryo can be sucked into the vacuum cavity 51 through the fine holes. After the vacuum device is used to draw a vacuum, the vacuum cavity 51 forms a vacuum, and the liquid of the wet embryo on the mold 1 is sucked, thereby accelerating the molding speed of pulp molding and quickly extracting the surface moisture.

[0032] Specifically, the heat insulation layer 4 includes a first heat insulation board 41 and a second heat insulation board 42. The first heat insulation board 41 is provided with a first opening 411 which is connected to the vacuum chamber 51. The second heat insulation board 42 is provided with a second opening 421 which is connected to the mold 1. The first opening 411 and the second opening 421 are connected to each other. The two layers of heat insulation boards are used for heat insulation to prevent the vacuum layer 5 and the mold frame 6 from being affected by high temperature. The first heat insulation board 41 and the second heat insulation board 42 are provided with a first opening 411 and a second opening 421 respectively to prevent the vacuum chamber 51 from affecting the extraction of moisture from the mold 1.

[0033] Furthermore, a plurality of heat-insulating blocks 43 are provided between the first heat-insulating board 41 and the second heat-insulating board 42, and a surrounding plate 44 is fixedly connected around the first heat-insulating board 41 and the second heat-insulating board 42. The heat-insulating blocks 43 separate the first heat-insulating board 41 and the second heat-insulating board 42 to improve the heat-insulating effect and reduce heat conduction. In order not to affect the vacuum equipment to evacuate the interior, the surrounding space is surrounded by the surrounding plate 44 to keep the interior sealed.

[0034] The working principle of the utility model is as follows: the wet embryo is transferred to the mold 1 by a manipulator, and the wet embryo is squeezed by the upper mold and the lower mold to squeeze out the internal moisture. The heating mold 1 in the present application is one of the upper mold and the lower mold. The upper mold and the lower mold are only different in the shape of the mold 1, and the other structures are the same. After the upper mold and the lower mold are combined, the two molds 1 squeeze the wet embryo to squeeze out the internal moisture. At this time, the mold 1 is heated by the nano heating ceramic 3 to accelerate the loss of moisture inside the wet embryo. At the same time, vacuum is drawn by a vacuum device to absorb the moisture of the wet embryo, thereby further improving the molding efficiency.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
