Description

Technical Field

[0001] The utility model relates to the technical field of paper tray production, and particularly relates to a movable paper tray hydraulic press. Background Art

[0002] Chinese Patent Document No. CN217378405U disclosed an automatic paper tray forming machine with a flanging function on September 6, 2022, belonging to the technical field of paper tray forming. It includes two mounting plates, a pulp tank is fixedly connected between the two mounting plates, and mounting frames are fixedly connected to the tops of the two mounting plates by screws. In the utility model, the lower die is driven by a cylinder to move and close the mold with the upper die base, so that the guide rod moves upward. By using the linkage effect among the guide rod, the first flat plate and the second flat plate, the gas inside the second airbag is conveyed into the interior of the first fixed box through the second air outlet hose. Under the action of the third spring, the gas inside the first fixed box enters the interior of the third airbag, driving the third flat plate, the round tube, the disc and the pin to move upward, and pushing out the impurities inside the filter holes, preventing a large amount of impurities from adhering to the inside of the filter holes after long-term use, which affects the suction work of the external vacuum pump, and thus preventing the forming quality of the paper tray from being affected. When discharging the formed product from this automatic paper tray forming machine, generally, workers manually take out the formed product at the forming station. However, such operation is rather troublesome and time-consuming. Moreover, when discharging, the paper tray forming machine cannot produce, resulting in low production efficiency of the paper tray.

[0003] Therefore, it is necessary to make further improvements. Summary of the Utility Model

When the lower die assembly moves to the forming station or the loading station, the slider acts on the limit switches so that the control device controls the driver to stop working.

[0014] A plurality of oil cylinder assemblies are arranged on the machine body. The oil cylinder assemblies are drivingly connected to the upper die assembly, and the oil cylinder assemblies drive the upper die assembly to move up and down to realize mold opening and mold clamping.

[0015] In the present utility model, the lower die assembly and the material guiding device are simultaneously movably arranged. When clamping the mold, the lower die assembly moves to the forming station for mold clamping, and at the same time, the material guiding device moves to the unloading station for discharging the paper trays. There is no need for manual operation to take out the formed products at the forming station, which makes the discharging operation convenient. In addition, when the paper trays are being discharged, the paper tray hydraulic press can carry out mold clamping production, greatly improving the production efficiency of the paper trays. When opening the mold, the lower die assembly moves to the loading station to facilitate the placement of semi-finished paper trays, and the material guiding device moves to the forming station to facilitate the reception of the finished paper trays. By moving in such a cycle, the production efficiency of the paper trays is further improved. Description of the Drawings
