Description

Technical Field

[0001] This utility model relates to the field of packaging box production technology, and in particular to a top corner device for a lid and top corner. Background Technology

[0002] A top-and-bottom box is a square, open-top box made of folded cardboard, such as a wine box, a mobile phone box, or a gift box. Its body is a top-and-bottom box, and its lid is another top-and-bottom box made of cardboard. The two boxes are slightly different in size.

[0003] During the production process, the top corners of the top and bottom covers need to be machined. Existing technologies commonly use methods such as... Figure 1 The cornering device shown is used to corner small-sized top and bottom covers. However, this cornering device cannot effectively adhere the cardboard surface to the cover, resulting in poor cornering performance and failing to meet the production needs of enterprises.

[0004] To address the aforementioned problems, this application discloses a top-and-bottom corner device for a roof. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model discloses a top corner device for a roof and subfloor. To achieve the above objective, the technical solution adopted by this utility model is as follows: a top corner device for a roof and subfloor, including a corner pressing head. The corner pressing head has a first straight edge symmetrically arranged on opposite sides. A first inclined edge that slopes inward and forms a 135° angle with the first straight edge is connected below the first straight edge. A second straight edge that slopes inward and forms a 135° angle with the first inclined edge is connected below the first inclined edge. A second inclined edge that slopes inward and forms a 135° angle with the second straight edge is connected below the second straight edge. The two corresponding second inclined edges on both sides of the corner pressing head are connected to form a 90° included angle.

[0006] More preferably, the apex indenter is made of a stainless steel block.

[0007] This utility model achieves the following beneficial effects:

[0008] The top corner device of this application can ensure effective adhesion between the cardboard surface and the device during use, thereby improving the quality of the top corner. Compared with the top corner device in the prior art, it meets the production requirements of enterprises and has strong practicality.

[0009] Other features and advantages of this invention will be set forth in the following description and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures pointed out in the description and the accompanying drawings. Attached Figure Description

[0014] 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.

[0015] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] Example

[0017] In order to solve such Figure 1 The shown corner device is not suitable for the production of small-sized top and bottom corner units. (Refer to...) Figure 2 As shown, this application discloses a corner-setting device for top and bottom covers, including a corner pressing head 10. The corner pressing head 10 has symmetrically arranged first straight edges 11 on opposite sides. A first inclined edge 12, tilted inwards and forming a 135° angle with the first straight edge 11, is connected below the first straight edge 11. A second straight edge 13, also forming a 135° angle with the first inclined edge 12, is connected below the first inclined edge 12. A second inclined edge 14, tilted inwards and forming a 135° angle with the second straight edge 13, is connected below the second straight edge 13. The two corresponding second inclined edges 14 on both sides of the corner pressing head 10 are connected and form a 90° included angle. Based on this structure, when processing the corners of small-sized top and bottom covers, it can ensure effective adhesion between the cardboard surface and the device, thus improving the corner quality. Compared with existing corner-setting devices, this device meets the production requirements of enterprises and has strong practicality.

[0018] In one specific implementation, the corner indenter 10 is made of a stainless steel block, which ensures the hardness of the corner device and prevents it from rusting.
