Description

Technical Field

[0001] The utility model relates to an elastic film box laminating and forming device with a cutter. Background Art

[0002] The elastic membrane box is composed of an upper box body and a lower box body. The upper box body and the lower box body have a box opening of the same shape and size. The box openings are covered with a highly elastic film. The box openings of the upper box body and the lower box body are tightly attached to each other to form a closed elastic membrane box. Finally, the fastening between the upper box body and the lower box body can be made of tape, plastic buckles, etc. The elastic membrane box can provide a perfect packaging solution for irregular or uneven surface products and devices. The elastic membrane box is very suitable for transporting 3D products, such as test sockets, optical devices, prisms, lenses and crystals. Put the product 22 into the box body, and it can be suspended between the two layers of film inside the box body. This can not only keep the original shape of the product well, but also safely fix the product in one place.

[0003] When the film is pasted on the box mouth, it can withstand the general pulling pressure like plastic wrap, and can easily adhere to glass ceramics, stainless steel pasta utensils, and smooth plastic products (but not the plastic wrap itself).

[0004] However, the adhesive force is sometimes insufficient to cause the film to separate from the box mouth. Therefore, it is necessary to press an annular pressing ring on the outer periphery of the box mouth so that the inner circle of the annular pressing ring and the outer periphery of the box mouth have an interference fit. The edge of the film is pressed between the inner circle of the annular pressing ring and the outer periphery of the box mouth, further improving the film fixing effect.

[0005] Currently, there are published patents: [CN] Film laminating and clamping device for elastic membrane boxes - CN210734560U. In order to facilitate the pressing of the annular pressure ring, the pressing is manually achieved by driving the handle. It can only achieve the pressing of a single elastic membrane box at a time, and requires a lot of manpower, with low work efficiency. At the same time, the laminating needs to be carried out at the front station through the laminating workbench to stick the film and cut the edges. The labor cost and device cost are high, and the production efficiency is low. Utility Model Content

At this time, the screw rod drives the workstation forward one group again, and the pressing group repeats the previous action, and at this time the cutting group is located directly above the previous group of workstations (initial workstation), and the lifting cylinder of the cutting group moves downward to drive the annular cutter to move down and cling to the outer edge of the annular pressure ring to cut the film between the cushion block and the box body, and the lifting cylinder resets after the cutting is completed, and then the pressing and cutting of the subsequent groups of workstations are completed in sequence to complete the film laminating and forming work of each group of elastic film boxes.
