Description

Technical Field

[0001] This utility model belongs to the technical field of irregular EPE molding and packaging equipment, specifically relating to an irregular EPE molding and packaging equipment. Background Technology

[0002] Irregularly shaped EPE molding packaging equipment is a specialized machine used to process expandable polyethylene, a flexible foam material with cushioning, shock absorption, and moisture-proof properties, into non-standard, customized packaging shapes. Its core working principle is to preheat and soften EPE sheets or rolls through an automated or semi-automated process. Then, using a special mold designed according to the specific product size and contour, the EPE material is precisely fitted into the mold shape through processes such as molding, vacuum forming, cutting, or heat sealing. The final product is an irregularly shaped cushioning packaging structure suitable for various items such as electronic components, home appliances, medical devices, baby products, and precision instruments. It can effectively meet the personalized protection needs of different products during transportation and storage, and also features high molding accuracy, stable production efficiency, and reduced material waste.

[0003] For irregularly shaped EPE molded packaging materials, the EPE groove and the EPE bottom flat sheet are connected by adhesive. However, when this connection method is disturbed by external forces, the bonding stability will be reduced. Therefore, the market needs a new device to solve the current problems. Utility Model Content

[0004] The purpose of this utility model is to provide a special-shaped EPE molding and packaging equipment to solve the problem of the special-shaped EPE molding and packaging material mentioned in the background art. The EPE groove and the EPE bottom flat sheet are connected by bonding. However, when this connection method is disturbed by external force, the bonding stability will be reduced. Therefore, the market needs a new device to solve the current problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-standard EPE molding and packaging equipment, including an EPE slot, an EPE bottom flat piece installed at the lower end of the EPE slot, square slots provided at the left and right ends of the EPE slot and the EPE bottom flat piece, connecting plates installed at the left and right ends of the EPE slot and the EPE bottom flat piece through the square slots, inserting an insertion plate fixed at the inner side of the connecting plate into the inner position of the square slot, a threaded hole provided in the inner position of the insertion plate, and insertion holes provided in the inner positions of both the EPE slot and the EPE bottom flat piece, with the two insertion holes communicating with each other.

[0006] Preferably, the EPE groove and the EPE bottom flat sheet are connected by an adhesive method.

[0007] Preferably, the connection between the EPE slot and the EPE bottom flat sheet forms an inner groove at the internal position.

[0008] Preferably, the insertion hole leads to a square slot, and a groove is provided at the lower end of the bottom flat plate of the EPE.

[0009] Preferably, the insertion plate is inserted into the interior of the square slot such that the center of the threaded hole is aligned with the insertion hole.

[0010] Preferably, a stainless steel bolt is inserted into the inner part of the groove.

[0011] Preferably, the stainless steel bolt is inserted from the inside of the groove, and can enter the inside of the insertion hole.

[0012] Preferably, the stainless steel bolt is inserted into the insertion hole and can be rotated to enter the internal position of the threaded hole.

[0013] Compared with the prior art, this utility model provides an irregularly shaped EPE molding and packaging equipment, which has the following beneficial effects: 1. This device involves inserting two insertion plates located on the inner side of the connecting plate into the square slots of the EPE slot and the EPE bottom flat plate, respectively. The stainless steel bolt is then inserted into the insertion hole from the groove at the lower end of the EPE bottom flat plate. By rotating the stainless steel bolt, it is pushed into the threaded hole. When the stainless steel bolt is fully inserted into the threaded hole, the head area of ​​the stainless steel bolt is located in the groove. This does not affect the installation of the EPE bottom flat plate. After installation, it can increase the stability of the connection between the EPE slot and the EPE bottom flat plate.

[0014] 2. To overcome the limitations of traditional EPE frame die-cutting processes, such as material waste and cumbersome splicing, this solution first uses a custom die to die-cut the EPE substrate. The design retains connecting bridges at the four corners, so that the die-cut EPE sheet has both a frame prototype and overall connectivity. When unfolded, it opens to both sides along the middle dividing line. The connecting bridges act as flexible hinges to guide the frame to naturally form a rectangular frame. The four corners form notches due to relative displacement. Then, a small amount of glue is applied to the notches, and the frame is quickly shaped into a rectangular frame based on the positioning of the connecting bridges. Multiple pieces can be die-cut at one time according to the machine size, which greatly improves production efficiency and reduces material waste. Finally, the formed frame is bonded to the bottom EPE flat sheet. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The utility model provides, for example Figure 1-4The illustrated irregular EPE molding and packaging equipment includes an EPE slot 1, an EPE bottom flat piece 2 installed at the lower end of the EPE slot 1, and square slots 9 provided at the left and right ends of the EPE slot 1 and the EPE bottom flat piece 2. Connecting plates 4 are installed at the left and right ends of the EPE slot 1 and the EPE bottom flat piece 2 through the square slots 9. The connecting plates 4 insert an insertion plate 5 fixed at the inner side into the inside of the square slots 9. The inside of the insertion plate 5 is provided with a threaded hole 6. Insertion holes 10 are provided at the inside of both the EPE slot 1 and the EPE bottom flat piece 2, and the two insertion holes 10 are connected.

[0023] Lay the EPE bottom flat sheet 2 flat on the bottom of the outer packaging box as the basic support surface for the product. Then, gently place the item to be packaged in the central area of ​​the EPE bottom flat sheet 2, ensuring that the bottom surface of the product is fully attached to the EPE bottom flat sheet 2. The foam elasticity of the EPE bottom flat sheet 2 absorbs the initial vertical stress. Next, pick up the upper part of the EPE slotted frame 1 and align it with the edge contour of the EPE bottom flat sheet 2, so that the inner groove wall of the frame surrounds the product. The slotted shape of the frame precisely matches the contour of the product, forming a lateral wrap-around protection. When the packaging is completed and enters the transportation process, if it encounters external forces such as bumps or collisions, the EPE bottom flat sheet 2 will buffer the vertical impact through the compression deformation of its own foam structure, while the EPE frame will disperse the horizontal energy through lateral elastic extension and rebound force. The two work together to isolate the external force from the product.

[0024] like Figure 1 and Figure 2 As shown, the EPE slot 1 and the EPE bottom flat plate 2 are connected by bonding. The connection between the EPE slot 1 and the EPE bottom flat plate 2 forms an inner groove 3 at the internal position. The insertion hole 10 leads to the square slot 9. A groove 8 is provided at the lower end of the EPE bottom flat plate 2. The insertion plate 5 is inserted into the internal position of the square slot 9, so that the center of the threaded hole 6 is aligned with the insertion hole 10. A stainless steel bolt 7 is inserted into the internal position of the groove 8. The stainless steel bolt 7 is inserted from the internal position of the groove 8 and can enter the internal position of the insertion hole 10. The stainless steel bolt 7 enters the insertion hole 10 and can enter the internal position of the threaded hole 6 by rotation.

[0025] The design retains connecting bridges at the four corners, allowing the die-cut EPE sheet to have both a basic frame shape and overall connectivity. When unfolded, it opens to both sides along the central dividing line. The connecting bridges act as flexible hinges, guiding the frame to naturally form a rectangular frame. The four corners form gaps due to relative displacement. A small amount of glue is then applied to the gaps, and the frame is quickly shaped into a rectangular frame based on the positioning of the connecting bridges. Multiple sheets can be die-cut at once according to the machine size, greatly improving production efficiency and reducing material waste.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
