[0023] Reference Figures 1-2 , Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2This is another structural schematic diagram of the present invention. A dual-station paper mold forming component includes: a lower mold assembly 21, a rotating assembly 22, and an upper mold assembly 23. The lower mold assembly 21 includes a vent pipe 211, a lower mold 212, and a connecting pipe 213. At least two lower molds 212 are installed on the circumferential side of the vent pipe 211, and at least two lower molds 212 are arranged side by side. The surface of the lower mold 212 adsorbs the pulp. The connecting pipe 213 connects the vent pipe 211 and the lower mold 212, and the connecting pipe 213 connects the inner cavity of the vent pipe 211 and the surface of the lower mold 212. This allows a negative pressure to be generated on the surface of the lower mold 212 or caused by the lower mold 212 being connected to the vent pipe 211 after the air pump is connected to the vent pipe 211. 12. Air is blown outward from the surface; the rotating component 22 is installed at one end of the air pipe 211 and drives the air pipe 211 to rotate around the central axis, so that the lower mold 212 can be rotated into the pulp by driving the air pipe 211 to rotate 180 degrees, and the negative pressure generated on the surface of the lower mold 212 will adsorb the pulp onto the surface of the lower mold 212 to form a wet blank. Then the air pipe 211 is rotated 180 degrees, so that the lower mold 212 adsorbing the wet blank rotates back to the initial position; and the number of upper mold components 23 is at least two, and at least two upper mold components 23 are arranged side by side and located directly above the air pipe 211. At least two upper mold components 23 work independently and apply pressure and adsorb and transport the wet blank on the lower mold 212.

[0024] This dual-station paper mold forming component uses two lower molds 212 arranged side by side on the circumferential surface of a ventilation pipe 211. After the lower mold 212 absorbs the pulp and forms a wet paper mold blank on its surface, two independently operating upper mold components 23 apply pressure to the wet paper mold blank on the surface of the lower mold 212 and remove the wet paper mold blank from the surface of the lower mold 212 for transport. This avoids the problem that traditional paper mold forming equipment can only produce one paper mold at a time and cannot produce multiple or various types of paper molds at the same time, which affects the production efficiency of paper molds.

[0025] The upper mold assembly 23 includes an upper mold drive 231 and an upper mold 232. The upper mold drive 231 is located directly above the vent pipe 211. The drive end of the upper mold drive 231 is connected to the upper mold 232, and the surface of the upper mold 232 is connected to an air pump, which allows the surface of the upper mold 232 to suck in and blow air. The upper mold drive 231 drives the upper mold 232 to move closer to and further away from the lower mold 212, so that the wet paper mold blank can be longitudinally transported through the cooperation of the upper mold drive 231 and the upper mold 232.

[0026] Specifically, the two upper mold components 23 are independently controlled. Each upper mold drive component 231 controls the upper mold 232 to move closer to or further away from the lower mold 212 to pick up and transport the paper mold wet blank. The position of the upper mold 232 can be adjusted according to the needs. For example, if a thinner paper mold is required, the moving distance of the upper mold 232 can be increased, so that when the lower mold 212 and the upper mold 232 are closed, the pressure between them increases, and the paper mold wet blank becomes thinner under pressure. When a thicker paper mold is required, the moving distance of the upper mold 232 can be reduced, so that when the lower mold 212 and the upper mold 232 are closed, the pressure between them decreases, and the paper mold wet blank becomes thicker, thereby achieving the effect of controlling the thickness and density of the paper mold.

[0027] Furthermore, during the production of paper molds, the suction and blowing of at least two lower molds 212 arranged side by side are independently controlled, so that the suction duration of the at least two lower molds 212 can be different, thereby achieving control over the thickness of the paper mold. For example, one lower mold 212 can suction throughout the entire process after entering the pulp, while the other lower mold 212 can pause for a few seconds before suctioning after entering the pulp. This makes the paper mold on the surface of the lower mold 212 that suctions throughout the entire process thicker than the paper mold that pauses for a few seconds before suctioning, further achieving the effect of controlling the thickness and density of the paper mold.

[0028] Specifically, when the upper mold 232 is transporting the wet paper mold blank on the surface of the lower mold 212, the surface of the lower mold 212 blows air outward while the surface of the upper mold 232 sucks air in, thereby separating the wet paper mold blank from the lower mold 212 and adsorbing it by the upper mold 232. This allows the upper mold drive 231 to drive the upper mold 232 to move, thus transporting the wet paper mold blank.

[0029] A dual-station paper mold forming component further includes a conveying assembly 24, which includes a conveying drive 241, a screw 242, and a mounting plate 243. The mounting plate 243 is connected to multiple upper mold drive components 231, forming an integral unit. When the mounting plate 243 moves, it can drive the multiple upper mold drive components 231 to move synchronously, conveying the paper mold wet blank adsorbed by the upper mold 232. The conveying drive 241 is disposed on one side of the mounting plate 243, and the screw 242 is connected to the drive end of the conveying drive 241. The conveying drive 241 drives the screw 242 to rotate. The screw 242 is connected to the mounting plate 243, so that when the screw 242 rotates forward and backward, it can drive the mounting plate 243 to move laterally, thereby enabling the upper mold 232 to convey the paper mold wet blank.

[0030] The transport assembly 24 also includes a guide rail 244, which is connected to the mounting plate 243. The transport drive component 241 drives the screw component 242 to rotate, so that the mounting plate 243 drives the upper mold drive component 231 to move along the guide rail 244. By setting the guide rail 244, the movement path of the mounting plate 243 is fixed, and the movement of the mounting plate 243 is more stable, reducing the pressure required to bear by the screw component 242.

[0031] A dual-station paper mold forming component further includes a limiting component 26, which is disposed on one side of the vent pipe 211 and limits the vent pipe 211. Thus, after the lower mold 212 rotates to the designated position, the limiting component 26 can limit the vent pipe 211, ensuring that the lower mold 212 can be aligned with the upper mold 232, thereby improving the stability of the pressure applied by the upper mold 232 to the wet paper mold blank and the adsorption effect on the handling of the wet paper mold blank.

[0032] Specifically, there are two limiting grooves 2113, and the two limiting grooves 2113 are located on opposite sides of the vent pipe 211, so that when the vent pipe 211 is limited, it can be limited once every 180 degrees of rotation.

[0033] The upper mold assembly 23 also includes an upper mold guide 233. One end of the upper mold guide 233 is connected to the upper mold 232, and the other end passes through the mounting plate 243, so that the movement of the upper mold 232 can be guided by the upper mold guide 233, and the stability of the upper mold 232 moving along the driving direction of the upper mold drive 231 can be improved, thereby improving the handling efficiency.

[0034] There are four lower molds 212, with two lower molds 212 located on one side of the circumference of the air pipe 211 and the other two lower molds 212 located on the opposite side of the air pipe 211. This ensures that every time the air pipe 211 rotates 180 degrees, two lower molds 212 will be in an upward-facing state, while the other two will be in the pulp, adsorbing the pulp. This ensures that the wet pulp blank can be transported once every time the air pipe 211 rotates 180 degrees, thus improving production efficiency.
