Description

Technical Field

Molding is mainly divided into pulping, molding, drying, shaping and other processes. According to the type of introduced materials, molding can shape paper products, ceramic products and other products. The existing pulp molding processing system usually includes a pulp suction mechanism, a drying mechanism, a shaping mechanism and a punching mechanism. The pulp is adhered to the pulp suction mold cavity by the pulp suction mechanism to form a wet blank, and then the pulp suction mold cavity is transferred to the drying mechanism for drying to obtain a hardened pulp product. Then the pulp product is moved to the shaping mechanism for hot pressing. After molding, it is trimmed by the punching mechanism to obtain a paper plastic product.

[0003] In the related art, for example, a Chinese patent with announcement number CN108951304B discloses a fully automatic energy-saving paper mold packaging left and right shaping and drying production equipment and process, including a quantitative slurry supply system, a cold press molding system, a pressure change transfer system, a hot press molding system, a finished product collection system and a PLC numerical control system; the PLC numerical control system controls the quantitative slurry supply system to quantitatively supply slurry; controls the cold press device in the cold press molding system to perform vacuum suction filtration molding; controls the pressure change transfer device in the pressure change transfer system to drive the transfer upper mold to move down to the first transfer station to absorb the molding blank, and when the hot press lower mold in the hot press molding system is transferred to the third transfer station, the transfer upper mold moves down to the second transfer station to transfer the molding blank to the hot press lower mold; controls the curing moving device in the hot press molding system to drive the hot press upper mold to move down and close the mold with the hot press lower mold and hot press curing and shaping; and controls the mechanical collection device in the finished product collection system to collect the shaped blanks onto the conveyor belt.

[0036] Reference Figure 2 and Figure 3 In this embodiment, there are two groups of hot pressing and shaping components 4, which are respectively arranged on the frame 1 on both sides of the pulp pool 2. The hot pressing and shaping components 4 include a hot pressing lower die 41, a hot pressing upper die 42, a heating component 43, an air pump 44 and a moving component 45. The hot pressing lower die 41 is installed on the frame 1. The hot pressing lower die 41 is made of aluminum alloy and its shape is roughly similar to the forming lower die 31.

[0042] Reference Figure 2 and Figure 3In this embodiment, the slurry supply component 6 includes a mixing barrel 61, a second delivery pump 62, an agitator 63, a flow detector 64, and a slurry recovery barrel 65.

The second delivery pump 62 is used to deliver the slurry in the mixing barrel 61 to the slurry pool 2; preferably, the material of the mixing barrel 61 should have good corrosion resistance, and can be made of stainless steel or fiberglass; the selection of the second delivery pump 62 should take into account its delivery capacity and durability, and a diaphragm pump or a screw pump can be selected.

[0047] The implementation principle of the embodiment of the present application is as follows: the double-station paper mold fully automatic forming device of the present embodiment effectively solves the problem that the wet embryo is easily damaged during the transfer process through reasonable structural design and efficient process flow. Specifically, the suction filtration of the suction pump 32 on the molding lower mold 31 can quickly form the wet embryo; the hot pressing upper mold 42 quickly absorbs the wet embryo through the action of the air pump 44 and transfers it to the hot pressing lower mold 41 for hot pressing and shaping. This process eliminates the problem of damage caused by demolding during the transfer of the wet embryo, simplifies the steps of hot pressing of the wet embryo transfer, and effectively solves the demolding problem of the wet embryo through a reasonably designed air path system, greatly reducing the scrap rate; the alternating operation of the two hot pressing and shaping components 4 greatly improves the production efficiency and meets the needs of large-scale production. The slurry in the mixing drum 61 is fully stirred and then accurately delivered to the slurry pool 2 by the second delivery pump 62, thereby ensuring the uniformity and consistency of the slurry. The flow detector 64 monitors in real time to ensure that the amount of slurry delivered each time meets the production process requirements, thereby avoiding waste caused by excessive delivery. The slurry recovery barrel 65 is provided to effectively recover the remaining slurry after suction filtration, thereby reducing resource waste and production costs. The addition of a finished product conveying line 5 realizes the efficient transfer of wet embryos and the smooth delivery of dry embryos, thereby further improving the degree of production automation and efficiency.
