[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by ordinary technicians in the technical field to which the present application belongs.

[0028] The utility model provides an elastic membrane box for facilitating installation of an elastic membrane, comprising a concave box body 1 and an elastic membrane 2 covering the upper surface of the concave box body 1, the concave box body 1 being made of plastic, the elastic membrane 2 being a transparent plastic membrane 2 with elasticity, an annular recessed groove 3 being provided on the upper surface of the upper annular edge of the concave box 1, an annular rubber ring 4 being fixedly embedded in the annular recessed groove 3, at least two annular seams 5 being provided on the upper surface of the annular rubber ring, the edge of the elastic membrane 2 being squeezed and embedded in the annular seam 5, and the annular seam 5 being able to expand under squeezing.

[0029] In order to increase the grip of the annular seam on the elastic membrane, the inner surface of the annular seam is provided with staggered convex nails 6, through which the friction force of the edge of the elastic membrane embedded in the annular seam can be increased.

[0030] Specifically, the cross section of the annular rubber ring is rectangular, and the annular rubber ring is bonded to the annular sink by glue.

[0031] The utility model provides a processing device for an elastic membrane box which is convenient for installing an elastic membrane, comprising an assembly line conveyor belt A1 and a concave box body 1 placed on the assembly line conveyor belt. The assembly line conveyor belt A1 can continuously convey the concave box body 1.

[0032] The conveyor belt of the assembly line has a first station for squeezing the edge of the elastic film into the annular seam, and a liftable pressing plate A2 is arranged above the first station. The liftable pressing plate A2 can be driven up and down by a cylinder, a hydraulic cylinder or an electric push rod, and an outer pressing frame A3 and an inner pressing frame A4 are arranged on the lower surface of the pressing plate. The outer pressing frame A3 is opposite to the outer annular seam 501, and the outer pressing frame A3 and the outer annular seam 501 have the same size, and the inner pressing frame A4 is opposite to the inner annular seam 502, and the inner pressing frame A4 and the inner annular seam 502 have the same size. The outer pressing frame is elastically connected to the pressing plate in the lifting direction, and the inner pressing frame is fixedly connected to the lower surface of the pressing plate, and the lower end of the outer pressing frame is lower than the lower end of the inner pressing frame, so that the outer pressing frame can squeeze the edge of the plastic film 2 into the outer annular seam 501 first. The elastic membrane is initially tightened and fixed, and when the liftable pressure plate continues to descend, the inner pressure frame squeezes the inner edge of the elastic membrane and embeds it into the inner annular gap, thereby further tightening and fixing the elastic membrane. At this time, since the outer pressure frame and the pressure plate are elastically connected in the lifting direction, the outer pressure frame is blocked and will not continue to move downward.

[0033] The inner pressure frame A4 and the outer pressure frame A3 are both rectangular frames, which are formed by bending a long thin rigid material into a rectangular frame, and the shape and size of the rectangular frame are the same as those of the annular seam.

[0034] The elastic connection between the outer pressure frame and the pressure plate in the lifting direction is specifically that a plurality of through holes A5 are provided on the pressure plate, a sliding rod A6 is slidably connected in the through holes, the lower end of the sliding rod is fixedly connected to the upper end of the outer pressure frame, and a spring A7 is provided between the upper end of the outer pressure frame and the lower surface of the pressure plate.

[0035] In addition, in order to prevent the elastic film from being separated from the annular seam when the two concave box bodies cover the product, the annular seam is misaligned relative to the center of the concave box body, so that the elastic film is compressed in the concave box body when the two concave box bodies cover the product.

[0036] The working principle of the elastic membrane box and processing equipment for facilitating the installation of the elastic membrane of the utility model is that the concave box body is transported to the first workstation by the assembly line conveyor belt (the elastic membrane has been covered on the upper surface of the concave box body by a robot or manually at the previous workstation), and then the liftable pressing plate is lowered, and the outer pressing frame first squeezes the outer edge of the elastic membrane into the outer annular gap to achieve initial tightening and fixing of the elastic membrane; and when the liftable pressing plate continues to descend, the inner pressing frame squeezes the inner edge of the elastic membrane into the inner annular gap to achieve further tightening and fixing of the elastic membrane.

[0037] The utility model has the advantages of simple structure, reasonable design, convenient manufacture, no need of manual assistance for installation, which is beneficial to improving processing efficiency, simple processing equipment and low manufacturing cost, which is beneficial to reducing costs.

[0038] The preferred embodiments listed above further illustrate the purpose, technical solutions and advantages of the utility model in detail. It should be understood that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
