[0034] The loading and unloading unit includes a bottom plate 201, an n-shaped bracket 202, and a support plate 203;

[0038] The n-shaped transmission rack 205 is driven up and down by the vertical hydraulic cylinder 206 to drive the transmission gear 204 to rotate, so as to adjust the horizontal and tilted state of the support plate 203. The tilted support plate 203 facilitates the loading of the composite plate onto the support plate 203 or the unloading of the composite plate from the support plate 203. The support blocks 207 are symmetrically fixed on both sides of the end of the support plate 203 away from the rotating shaft, so as to support the bottom edge of the composite plate when the support plate 203 is tilted.

[0039] The unloading unit includes a horizontal hydraulic cylinder 208, a transverse connecting plate 209, a vertical arm 210, and a push rod 211;

[0040] The horizontal hydraulic cylinder 208 is installed on the top of a base plate 201, the transverse connecting plate 209 is installed on the output end of the horizontal hydraulic cylinder 208, and the vertical arm 210 is fixed on the top of the transverse connecting plate 209;

[0041] There are multiple push rods 211, which are evenly distributed in the vertical direction and fixed to one end of the vertical arm 210. The number and position of the push rods 211 correspond to the support plate 203 one by one, and the bottom level of the push rod 211 is flush with the top level of the support plate 203 in a horizontal state.

[0042] The horizontal connecting plate 209, the vertical arm 210 and the pushing rod 211 are driven by the horizontal hydraulic cylinder 208 to horizontally approach the support plate 203, so as to push the composite plate blank on the support plate 203 onto the hot pressing plate 103. At the same time, the composite plate blank pushes the composite plate formed on the hot pressing plate 103 onto another set of support plates 203.

[0043] In this embodiment: it is necessary to add that: the side end faces of the plurality of heat-sealing plates 103 are provided with limit blocks, and the lengths of the limit blocks decrease from top to bottom, and the external end face of the molding machine body 101 is provided with fixed blocks matching the limit blocks, which are used to realize the different height positioning of the heat-sealing plates 103, and the multiple heat-sealing plates 103 can be driven to be pressed close to each other by the pressing hydraulic cylinder 102, and the side faces of the heat-sealing plates 103 are connected to the external heat source through the pipeline, which is used to realize the hot pressing operation of the plate, and the above structures are all prior art, so they are not elaborated on;

[0044] During the operation of the multi-layer hot pressing forming machine 1, the next batch of blank plates to be hot pressed can be pre-loaded, and the operation steps are as follows:

[0045] First, start the vertical hydraulic cylinder 206 in a group of loading and unloading units close to the unloading unit, so that the vertical hydraulic cylinder 206 drives the n-type transmission rack 205 to move upward, and the n-type transmission rack 205 drives multiple support plates 203 to rotate downward to an inclined state through the transmission gear 204. At this time, the blank plate can be inserted from the side to each support plate 203, and its support block 207 can support the bottom of the blank plate;

[0046] Then, the vertical hydraulic cylinder 206 is started in reverse to move the n-shaped transmission rack 205 downward. At this time, the multiple support plates 203 drive the blank plate to rotate from an inclined state to a horizontal state, thereby completing the blank plate pre-loading operation;

[0047] When the multi-layer hot pressing forming machine 1 is completed, the pressing hydraulic cylinder 102 moves downward to reset to the initial state, and the multiple heat-sealing plates 103 are separated and unfolded in sequence, and finally the upper surface of the heat-sealing plate 103 is flush with the upper surface of the support plate 203. At this time, the horizontal hydraulic cylinder 208 is started to drive the horizontal connecting plate 209, the vertical arm 210, and the push rod 211 to approach the support plate 203 with the blank plate placed thereon, and the push rod 211 contacts the blank plate and pushes the blank plate to move to the top of the hot pressing plate 103. The blank plate will push the molded composite plate on the top of the hot pressing plate 103 onto another group of support plates 203. Finally, the blank plate is completely moved to the upper surface of the hot pressing plate 103, and a part of the molded composite plate is still on the hot pressing plate 103.

[0048] At this time, the vertical hydraulic cylinder 206 corresponding to the other group of support plates 203 is started to rotate the other group of support plates 203 to an inclined state, and the formed composite plate is driven to rotate to an inclined state, and slowly slides downward under its own gravity to contact the support block 207, so that the formed composite plate is completely separated from the hot pressing plate 103, and then the multi-layer hot pressing molding machine can be started again to heat-seal the blank plate. At this time, the third batch of blank plates can be loaded, and the formed composite plates on the other group of support plates 203 can be unloaded. After unloading, the other group of support plates 203 is reset to a horizontal state;

[0049] Such reciprocating operation can realize rapid hot pressing of composite sheet materials. Compared with the traditional operation mode of unloading first and then loading, the operation of synchronous loading and unloading effectively reduces the idle waiting time of the multi-layer hot pressing molding machine 1, and further improves the working efficiency of the multi-layer hot pressing molding machine 1.

[0050] Please refer to Figures 1 to 3A limiting groove for vertical movement of the lateral part of the n-type transmission rack 205 is provided at the position where the n-type bracket 202 contacts the n-type transmission rack 205, and is used to limit and guide the up and down movement of the n-type transmission rack 205;

[0051] The unloading unit further includes a convex sliding block 212 and a convex sliding groove 213;

[0052] The convex slider 212 is symmetrically fixed on both sides of the bottom of the horizontal connecting plate 209 , the convex slide groove 213 is symmetrically opened on both sides of the top of a bottom plate 201 and passes through one end of the bottom plate 201 , and the convex slider 212 is limitedly slidably connected to the convex slide groove 213 .

[0053] In this embodiment: the limit groove is used to provide space for the up and down movement of the n-type transmission rack 205, and at the same time prevent the n-type transmission rack 205 from being offset, thereby ensuring the meshing stability between the n-type transmission rack 205 and the transmission gear 204;

[0054] The cooperation between the convex sliding groove 213 and the convex sliding block 212 can provide support and guidance for the movement of the transverse connecting plate 209, thereby ensuring the movement stability of the transverse connecting plate 209.

[0055] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
