At present, the pulp molding is a green and environment-friendly product which is made by using plant fiber pulp or waste paper products which can be completely naturally degraded and recycled as base materials, and the manufacturing process of the pulp molding is finished by the working procedures of pulping, adsorption forming, wet blank transfer, hot-press forming and the like; the method is widely applied to the fields of food and medicine containing, electric appliance packaging, planting and seedling raising, medical utensils, artware bottom blanks, fragile product liner packaging and the like.

In the prior art, the production process of the paper pulp molding product is the working procedures of continuous and repeated cyclic pulping, adsorption molding, wet embryo transfer, hot-pressing and shaping and the like. In each cycle, the hot press forming process takes most of the time, and other processes are in a shutdown standby state. Therefore, the production efficiency of the whole machine is generally low.

However, in the production process of rotary hot press forming, the mould moves around the working circle at a constant speed and is dynamic, which is completely different from the fixation of the former mould. Therefore, new technical solutions are necessary for the process connections related to the hot press forming die, such as wet embryo transfer and product demolding.

In the preferred embodiment of the present invention, an anti-falling mechanism is further provided, which comprises two anti-falling lock plates 81 fixedly mounted on the top surface of the arc-shaped guide plate 20, two anti-falling locks 82 rotatably mounted on the wet embryo transfer arm 10, and an anti-falling cylinder 83; an output shaft of the anti-falling cylinder 83 is respectively pivoted with one end of each of the two anti-falling lock catches 82 through a connector, and a keyhole is arranged on the anti-falling lock plate 81; a through hole for the anti-falling lock plate 81 to pass through is arranged on the wet embryo transfer arm 10 corresponding to each anti-falling lock plate 81; after the anti-falling lock plate 81 passes through the through hole, the anti-falling cylinder 83 drives the two anti-falling locks 82 to rotate, so that the free ends of the two anti-falling locks 82 are respectively inserted into the keyhole holes of the two anti-falling lock plates 81; the anti-falling cylinder 83 is fixedly arranged on the wet embryo transfer arm through an anti-falling mounting plate; the anti-falling lock catch is a Z-shaped thin steel plate, and a pin joint hole is formed in the anti-falling lock catch. The anti-falling lock plate is arranged at a corresponding position on the lifting mounting plate. The rest are assembled into a body on the anti-falling mounting plate and are integrally mounted on the wet embryo transfer arm.

The working principle of the anti-falling mechanism is as follows: the anti-falling cylinder is a single-acting cylinder, namely, a spring is arranged in a rod cavity in the front of the anti-falling cylinder and is not connected with compressed air, a piston rod of the cylinder is pushed to extend outwards after a rodless cavity in the back of the anti-falling cylinder is connected with the compressed air, and if the back cavity is decompressed, the piston rod is pushed to reset backwards by the spring in the front cavity. The connecting head arranged on the piston rod pushes and pulls the anti-falling lock catches on the two sides to swing forwards and backwards around the pin-jointed shaft, so that the lock heads of the anti-falling lock catches on the two sides are pulled out and inserted into the lock holes of the anti-falling lock plate, and the purposes of unlocking and locking are achieved. Because the lifting cylinder is a double-acting cylinder controlled by a three-position five-way valve, when the power is off, the three-position five-way valve is automatically stopped at the middle position, and compressed air in the cylinder is blocked, so that the lifting mounting plate and all mechanism parts mounted below the lifting mounting plate are kept at the original high positions. The anti-falling cylinder moves backwards by the return of the spring due to the power failure and the air break, the connecting head arranged on the piston rod pulls the anti-falling lock catches on the two sides to swing around the pin-jointed shaft, and the anti-falling lock catch lock head is inserted into the lock hole of the anti-falling lock plate to complete the anti-falling lock catch function. The anti-falling mechanism is only arranged for preventing the lifting cylinder from possible pressure loss, and is an effective measure without potential safety hazard.

In the preferred embodiment of the present invention, the present invention further comprises at least two plate chain assemblies 90, the plate chain assemblies 90 comprise an upper mounting plate 91 fixedly mounted on the bottom surface of the lifting mounting plate 30, a lower mounting plate 92 fixedly mounted on the top surface of the arc-shaped guide plate 20, and at least two hinge plates 93, and the at least two hinge plates 93 are hinged from top to bottom in sequence; two adjacent hinge plates are hinged to each other through a first hinge shaft 94; the upper mounting plate 91 is hinged to the uppermost one of the hinge plates; the lower mounting plate 92 is hinged with the lowermost hinge plate; the axes on which the first hinge shafts 94 of the adjacent two plate link chain assemblies 90 are located intersect. Specifically, at least two plate link assemblies 90 are evenly spaced circumferentially around the central axis of the lift mounting plate 30, which is designed to maintain a more stable structure during up and down operations.

In the preferred embodiment of the present invention, the plate link assembly 90 comprises two hinge plates, the upper hinge plate is hinged to the upper mounting plate 91; the lower hinge plate is hinged with the lower mounting plate 92; the length of the hinge plate positioned above is less than that of the hinge plate positioned below; the sum of the length of the hinge plate located above and the length of the upper mounting plate 91 is less than or equal to the length of the hinge plate located below. Thus, when folding, the upper mounting plate 91 and the hinge plate above can be folded on the hinge plate below, so as to prevent the hinge shafts from overlapping to affect the folding angle. Similarly, when the stent is deployed, a stable support state with a narrow top and a wide bottom is formed.

Further, the upper mounting plate 91 and the lower mounting plate 92 are hinged to the adjacent hinge plates through second hinge shafts 95; the first hinge axis 94 is located at an inner side of the second hinge axis 95, i.e., the second hinge axis 95 and the first hinge axis 94 do not overlap when folded. In addition, the first hinge shaft 94 is relatively located at the inner side of the second hinge shaft 95, so that when the two hinge plates are stretched to the maximum angle, because the first hinge shaft 94 is located at the inner side relative to the second hinge shaft 95, the trend that the first hinge shaft 94 moves relatively inwards when moving up and down can be ensured, and the phenomenon that the two hinge plates are possibly folded over dead points and folded back can be effectively prevented. All plate link chain components 90 are guided by the inner guide to move up and down, and the structure is stable.

Other examples are as follows:

the plate chain components can also be arranged in four directions, and the four plate chain components are uniformly distributed in four corners and have the same stable structure. Of course, if necessary, the more the number of plate link assemblies is, the better the structural stability is, and the customer can adjust the plate link assemblies according to the actual needs. The driving mechanism can also be a hydraulic oil cylinder; the number of the hollow rectangular tubes is two, four, five or more; the shape of the air pumping opening is oval, rectangular, square or other irregular shapes, and the shape of the pressure relief opening is oval, rectangular, square or other irregular shapes correspondingly. The method can be adjusted according to actual needs. While only certain features and embodiments of the application have been illustrated and described, many modifications and changes may occur to those skilled in the art (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the scope and spirit of the invention in the claims.

Finally, it should be noted that: the above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
