Description

Technical Field

[0002] The plastic sheet cup making machine is a mechanical equipment used to produce plastic cups. Its main working principle is to heat and soften the plastic sheet, then feed it into the cup-making mold, use compressed air or vacuum to blow the plastic sheet into shape, and then cut it with a knife. The plastic sheet cup making machine is an efficient and stable plastic cup production equipment with broad application prospects. Plastic cups are a kind of container widely used in daily life, mainly used in beverage stores, hot and cold drink stores, milk tea shops, hotels, restaurants and coffee shops, etc., to provide people with convenient beverage containers.

[0003] After the plastic sheet enters the die head of the plastic sheet cup making machine, the plastic sheet is blown into shape into the required plastic cup. After the plastic cup is formed, it needs to be removed from the mold and the cup is taken out. The process of taking out the cup is mostly done by removing the formed plastic cup by a cup-removing mechanism and placing it on a collection table. This way of taking out the cups easily causes the successfully taken out plastic cups to scatter on the table, causing the table to be messy and the plastic cups to roll around.

[0021] The above scheme is adopted: the first motor 15 starts to drive the transmission shaft 14 to rotate, the transmission shaft 14 drives the turbine rod 13 to rotate, the turbine rod 13 is meshed with the bevel gear 7, the bevel gear 7 drives the rotating screw 6 to rotate inside the limit frame 4, the threaded block 8 and the rotating screw 6 are threadedly rotated, the threaded block 8 moves up, the threaded block 8 drives the sliding block 9 to move up along the arc-shaped slide groove, the fixed column 11 drives the moving plate 10 to move through the threaded block 8, and the moving plate 10 drives the material placing plate 18 to move, so that the top of the plastic cup 20 falls off from the inside of the material placing ring 19 to the bottom of the material placing ring 19, and the plastic cup 20 can be accumulated and stacked again. After the plastic cup 20 is accumulated to a certain height, the plastic cup 20 is completely removed, and the first motor 15 drives the turbine rod 13 to rotate in the opposite direction to move the material placing plate 18 down, and a new round of finished product stacking can be carried out; The support plate 3 is supported and fixed by the mounting platform 2, the support plate 3 supports the limit frame 4, the limit frame 4 is fixed by the support plate 3, the threaded block 8 is limited by the sliding block 9, the movable plate 10 supports and fixes the material placing plate 18, the turbine rod 13 and the transmission shaft 14 are both located inside the mounting platform 2, the bottom of the first motor 15 is fixedly connected to the mounting platform 2, the bottom of the fixing plate 16 is fixedly connected to the mounting platform 2, one side of the connecting plate 17 is fixedly connected to the limit frame 4, and the other side of the connecting plate 17 is fixedly connected to the mounting platform 2; The support plate 3 enables the limit frame 4 to be fixed, and the rotating screw 6 is movably connected to the limit frame 4 through the first rotating hole, so that the rotating screw 6 can smoothly rotate inside the limit frame 4. When the rotating screw 6 rotates, it can drive the threaded block 8 to move up and down, so that the sliding block 9 slides up and down along the arc groove. The mounting table 2 limits and fixes the first motor 15, and the moving plate 10 can slide up and down through the rectangular sliding groove. The limit frame 4 supports and limits the rotating screw 6; The limit frame 4 can be fixed on both sides of the mounting platform 2 through the connecting plate 17, and the mounting platform 2 is fixed to the connecting plate 17.
