When one group of mold tooling 5 is displaced to the bottom of the feeding tooling 3 for feeding, the other group of mold tooling 5 is displaced to the bottom of the pressing tooling 4 for synchronous pressing and molding. Then, based on the cyclic dislocation displacement of the two groups of mold tooling 5, the pet food is fed and pressed synchronously without stopping.

A pressing template 45 which is vertically opposite to the mold tool 5 is fixed to the bottom end of the support of the second hanging support frame 44, and a plurality of groups of pressing die heads 46 are arranged on the surface of the pressing template 45. The two ends of the support of the second support frame 41 are symmetrically connected with the second hanging support frame 44.

Subsequently, by controlling the telescopic brake of the second electric push rod 43, under the guidance of the arm force of the second lifting guide rod 42, the combination of the pressing template 45 and the pressing die head 46 is pushed downward to different heights in turn, so as to perform a molding process on the pet food in the mold tooling 5.

[0025] The working principle of the present invention is as follows: when the pet food is molded by the pressing mold, the brake motor 14 is first controlled to work, driving the combined transmission of the brake pulley 15, the transmission belt 17, and the transmission pulley 18, and then driving the first screw rod 6 to rotate, and the meshing transmission of the first mating gear 12 and the second mating gear 13 is used to drive the first screw rod 6 and the second screw rod 9 to operate in linkage, and the first screw rod 6 and the second screw rod 9 are driven to rotate symmetrically in the forward and reverse directions by the forward and reverse symmetrical rotation of the first screw rod 6 and the second screw rod 9, and the first slide 8 and the second slide 11 on the shaft rod are driven to slide symmetrically in the forward and reverse directions along the guide rail directions of the first slide rail 7 and the second slide rail 10 in turn, and the corresponding two sets of mold tooling 5 are driven to be symmetrically displaced in a relative state; Further, when one group of mold fixtures 5 is displaced to the bottom of the feeding fixture 3 for feeding, the other group of mold fixtures 5 is displaced to the bottom of the pressing fixture 4 for synchronous pressing and molding. Then, based on the telescopic brake of the first electric push rod 33 in the feeding fixture 3, the combination of the feeding template 35 and the feeding tube 36 is pushed down to the die groove 53 port in the mold fixture 5, and the pet food raw materials are fed into the die groove 53. Synchronously, based on the telescopic brake of the pressing fixture 4, the combination of the pressing template 45 and the pressing die head 46 is pushed down into the die groove 53 in the mold fixture 5, and the pet food inside is synchronously molded and molded. Then, based on the cyclic displacement of the two sets of mold fixtures 5, the pet food is fed and pressed synchronously in a cyclic and non-stop manner. After each pressing and forming of the pet food in the mold fixture 5, the power of the electromagnetic magnet 59 is gradually reduced, so that the magnetic attraction of the electromagnetic magnet 59 on the iron ring 58 is gradually reduced until it disappears. While the magnetic attraction is gradually released, based on the elastic force combination of the compression spring 56 and the lifting guide rod 55, the supporting mold seat 57 is pushed to support along the mold groove 53, so that the pet food pressed in the mold groove 53 is pushed out. , so as to facilitate the integrated material collection of pet food, saving the operation time and difficulty of the operation. After the material collection is completed, the electromagnetic magnet 59 is energized again to generate magnetic attraction, which attracts the iron ring 58, so that the top support mold base 57 moves down and resets, exposing the mold groove 53 as the loading tooling groove for the next group of pet food. Then, this type of method is installed to press and form the pet food while simultaneously loading the pet food. The pressing process is performed in a cyclic and continuous form, which is suitable for the continuous production process of the modular form of the production line.
