Description

TECHNICAL FIELD

[0002] Elastic film box is very suitable for transporting 3D products, such as test seats, optical devices, prisms, lenses and crystals. The product is placed in the box body, and it can be suspended between the two membranes inside the box body. In this way, the product can be well maintained in its original state and safely fixed in one place.

[0003] The elastic film box is composed of a box-shaped upper cover and a lower cover. Both the upper cover and the lower cover have an opening of the same shape and size, and a high-elasticity film covers the opening. The upper opening and the lower opening are tightly attached to each other to form a sealed elastic film box. Finally, the fastening between the upper opening and the lower opening can be achieved by using adhesive tape, plastic buckle, etc.

[0004] Currently, when covering the film on the opening of the lower cover of the elastic film box, in order to avoid the film from being detached from the opening, a ring-shaped pressing ring is usually pressed on the outside of the opening after covering the film on the opening. Thus, the edge of the film is pressed tightly between the inner ring of the ring-shaped pressing ring and the outer wall of the opening, further improving the fixation of the film on the opening. The existing lower cover of the elastic film box is covered with film one by one by manual operation, and then the film is further fixed by manually pressing the ring-shaped pressing ring. After that, the lower cover with the preliminarily pressed ring-shaped pressing ring is sent into a film pressing equipment (for example, a film covering and pressing device for elastic film box disclosed in Chinese patent publication No. CN210734560U) for pressing, so as to press the ring-shaped pressing ring into place. However, the film covering and pressing device for elastic film box disclosed in the above patent can only press one lower cover at a time, which has low work efficiency, and manual operation is required to drive the handle for pressing each time, which is not convenient to operate.
