The pre-cutting process of the raw paper can be carried out through the lower pre-cutting fixing plate 17 and the upper pre-cutting mold 20 to prevent the coating layer of the raw paper from being directly stamped and formed, which would cause tearing. Several upper pre-cutting molds 20 make the pre-cutting of the raw paper more efficient.

[0039] like Figure 2 , Figure 3 and Figure 5 As shown, the lower mold drive assembly includes a drive bracket 21. The bottom of the drive bracket 21 is bolted to two bases 1.

The two guide rods are symmetrically distributed along the center of the drive bracket 21, and their tops are connected to the bottom of the lower embossing base plate 10 or the lower pre-cut base plate 16.

[0040] The drive bracket 21 provides support for the installation of the lower mold cylinder 22. The lower mold cylinder 22 raises or lowers the lower embossing base plate 10 or the lower pre-cutting base plate 16 through its piston rod. The raising or lowering of the lower embossing base plate 10 or the lower pre-cutting assembly can drive the raising or lowering of the lower embossing mold 12 or the lower pre-cutting fixing plate 17.

At the same time, the adjusting bracket 26 can establish a connection between the transition plate 6, the rotating component, the active roller 4 and the driven roller 5. The rotating motor 27 drives the active roller 4 to rotate accordingly. The active roller 4 and the driven roller 5 cooperate to allow the base paper to move from the base paper transition plate 7 to between the active roller 4 and the driven roller 5, and then enter the surface of the lower embossing mold 12.

[0043] like Figure 4 As shown, the second adjustment component includes an adjustment connecting plate 28. The top of the adjustment connecting plate 28 is bolted to the lower embossed fixing plate 11, and an adjustment side plate 29 is bolted to one side of it. An adjustment groove 30 is provided on the adjustment side plate 29, and an adjustment bolt 31 is provided on the adjustment groove 30. The adjustment bolt 31 is connected to the active seat 23.

The active seat 23 is connected to the driven roller 5, the first adjusting component, the transition base plate 6 and the paper transition plate 7 through the adjusting bracket 26. Therefore, by adjusting the position of the adjusting bolt 31 on the adjusting groove 30, the active seat 23 can be adjusted. The adjustment of the active seat 23 can ultimately adjust the height of the paper transition plate 7 accordingly, so that the paper transition plate 7 and the lower embossing mold 12 are on the same horizontal plane, the paper can pass through better, and the adaptability of the paper transition plate 7 to different lower embossing molds 12 is enhanced.

[0045] like Figure 6 As shown, the lower forming assembly includes a lower forming base plate 32, which is bolted to the forming bracket 9. A lower forming fixing plate 33 is provided on the top of the lower forming base plate 32, and several lower forming molds 34 are provided on the lower forming fixing plate 33. A guide plate 35 is provided on the top of the lower forming mold.

The forming drive assembly includes a forming mounting plate 39, which is mounted on four forming support columns 8. A forming drive component 40 is provided on the forming mounting plate 39, and the piston rod of the forming drive component 40 is connected to the top of the upper forming base plate 36.

[0046] The forming bracket 9 provides overall support, the guide plate 35 guides the raw paper entering this process, the forming support column 8 is connected to the upper forming base plate 36 and the lower forming base plate 32, and the forming support column 8 is slidably connected to the lower forming base plate 32, the lower forming fixing plate 33 provides corresponding support for the lower forming mold 34, the upper forming fixing plate 37 provides corresponding support for the upper forming mold 38, the forming drive component 40 raises and lowers the upper forming base plate 36 through its piston rod, the raising and lowering of the upper forming base plate 36 can drive the upper forming fixing plate 37 to raise and lower, the upper forming fixing plate 37 makes the upper forming mold 38 fit with the upper surface of the raw paper, at the same time, the lower forming mold 34 fits with the lower surface of the raw paper, the upper forming mold 38 and the lower forming mold 34 perform forming operation on the raw paper.

[0047] like Figure 5 and Figure 6As shown, the paper-supporting transition assembly includes a first transition roller 41, which is bolted to the lower pre-cut base plate 16 by first transition frames 42 at both ends. It also includes a second transition roller 43, which is bolted to the lower forming base plate 32 by second transition frames 44 at both ends. A paper support plate 45 is provided between the first transition roller 41 and the second transition roller 43.

[0048] During the process of the raw paper entering the lower forming mold 34 from the lower pre-cutting fixing plate 17, it first passes through the first transition roller 41, then enters the support plate 45, and then enters the surface of the lower forming mold 34 from the support plate 45 through the second transition roller 43. The first transition frame 42 and the second transition frame 44 provide support for the first transition roller 41 and the second transition roller 43, respectively. The support plate 45 provides a connection for the raw paper to move from the lower pre-cutting fixing plate 17 to the lower forming mold 34, so that it will not fall off during this process.

[0049] Working principle: By adjusting the position of the adjusting bolt 31 on the adjusting groove 30, the active seat 23 can be adjusted. The adjustment of the active seat 23 can ultimately adjust the height of the paper transition plate 7, so that the paper transition plate 7 and the lower embossing mold 12 are on the same horizontal plane. The piston rod of the adjusting cylinder 25 drives the driven seat 24 to rise and fall through the adjusting joint, so as to adjust the distance between the active roller 4 and the driven roller 5 to adapt to the paper of the corresponding thickness. The paper passes over the paper transition plate 7 and enters between the active roller 4 and the driven roller 5. The rotary motor 27 drives the active roller 4 to rotate, which cooperates with the driven roller 5 to make the paper leave between the active roller 4 and the driven roller 5 and enter the surface of the lower embossing mold 12. The lower mold cylinder 22 raises the lower embossing base plate 10 through its piston rod, so that the lower embossing mold 12 and the upper embossing mold 15 press against the paper. After embossing is completed, the lower die cylinder 22 drives the lower embossing die 12 to reset, and the raw paper enters the lower pre-cutting fixing plate 17. The lower die cylinder 22 drives the lower pre-cutting base plate 16 to rise, so that the lower pre-cutting fixing plate 17 and the upper pre-cutting die 20 pre-cut the raw paper. The lower die cylinder 22 drives the lower pre-cutting base plate 16 to reset, and the raw paper leaves the lower pre-cutting fixing plate 17 and passes through the first transition roller 41, the support plate 45 and the second transition roller 43 in sequence, and finally enters the surface of the lower forming die 34. During this process, the guide plate 35 guides the raw paper. The forming drive component 40 lowers the upper forming base plate 36 through its piston rod. The upper forming die 38 and the lower forming die 34 perform forming operations on the raw paper. After the operation is completed, the forming drive component 40 drives the upper forming base plate 36 to reset, and the formed raw paper enters the next process.
