Description

Technical Field

[0001] The utility model relates to the technical field of plastic cup processing, in particular to a plastic cup processing device. Background Art

[0002] The height of disposable plastic cups is generally less than 10cm, and the capacity is small, so they are not suitable for use in situations where there is a large demand for drinking water. For example, athletes drink a large amount of water at a time and drink frequently, and the amount of water they drink during one exercise can reach at least 500ml. After using a conventional disposable cup to collect water, athletes need to go to the water dispenser to collect water again after drinking a cup of water as they replenish water intermittently, which affects the training rhythm of each group. The traditional processing method of extruding and cutting the film-like raw materials into shape will further thin the large plastic cups, and the stability of placement will be poor, and they will be easily damaged and deformed. This processing method is not suitable for processing larger plastic cups. Utility Model Content

[0015] The beneficial effects of the plastic cup processing equipment of the utility model are:

[0016] The use of plastic cup blanks that are thicker than traditional plastic films is conducive to the processing of large plastic cups. The plastic cup blank loading mechanism can place two layers of plastic cup blanks, and the upper side pusher is used to push the plastic cup blanks on the upper tray onto the mold rod, and the lower side pusher is used to push the plastic cup blanks on the lower tray through the second opening. When squeezing through the second opening, the plastic cup blanks are deformed and fall into the inner mold cavity on the lower side. Subsequently, the upper tray, the lower tray and the pusher are driven backward to separate from the mold base by the first electric push rod, and the distance between the two mold bases is driven to decrease by the third electric push rod, so that the mold rod enters the two inner mold cavities, and the plastic cup blanks are squeezed into plastic cups. Finally, the plastic cups are taken backwards to separate from the mold rod. BRIEF DESCRIPTION OF THE DRAWINGS

The pushing piece 9 on the upper side can pass through the first opening 2 from top to bottom, and the pushing piece 9 on the lower side can pass through the second opening 5 from top to bottom. The height of the pushing piece 9 is driven by the second electric push rod 8. All the pushing pieces 9 are fixed to the connecting frame 3. The movable end of the second electric push rod 8 is arranged upward. The movable end of the second electric push rod 8 is fixed to one of the pushing pieces 9, for example, the left end of the upper pushing piece 9. The housing of the second electric push rod 8 is fixed to the base 7. The base 7 is on the movable end of the first electric push rod 6. The movable end of the first electric push rod 6 is arranged backward.

When the two mold bases 12 are closed, a mold cavity of a plastic cup is formed between the two inner mold cavities 13 and the mold rod 14. The length of the mold rod 14 is 10-30 cm, the front part of the mold rod 14 forms the cup mouth, and the rear part of the mold rod 14 is the position of the cup bottom. The spacing between the two mold bases 12 is adjusted by a linear drive mechanism.

[0029] The linear drive mechanism is a hydraulic cylinder or a third electric push rod 11. When the linear drive mechanism is the third electric push rod 11, the movable end of one of the third electric push rods 11 is arranged upward and fixedly connected to the mold base 12 located on the upper side, and the movable end of the other third electric push rod 11 is arranged downward and fixedly connected to the mold base 12 located on the lower side, and the other third electric push rod 11 is fixedly connected to the frame 10. The installation method of the hydraulic cylinder is the same as that of the third electric push rod 11. When the number of mold bars 14 and the inner mold cavity 13 used in conjunction are increased, the upper tray 1, the lower tray 4 and the push piece 9 also need to be more adaptable, which also increases the volume of the mold base 12 and the weight.
