Description

Technical Field

[0001] This utility model relates to the field of milk packaging box production technology, specifically to a punching tool for the water droplet opening of milk packaging boxes. Background Technology

[0002] Milk is a common dairy product, widely recommended as part of a daily diet due to its rich nutritional content. It's not only suitable for children's growth but also plays an important role in adult health. The calcium, phosphorus, and vitamin D in milk work together to help maintain bone density and strength, making it especially suitable for children, adolescents, and the elderly. Milk is generally packaged in two ways: flexible packaging and rigid packaging. Flexible packaging is made of composite materials such as plastic film, making it lightweight and easy to carry, but it is easily damaged and oxidized, and its taste is slightly inferior, making it suitable for short-term consumption. Rigid packaging, such as cardboard boxes, is sturdy and pressure-resistant, with strong barrier properties, and can retain the sweetness and taste of the milk, making it suitable for long-term storage. Comparatively, consumers tend to prefer purchasing milk in rigid packaging.

[0003] In the existing technology, when drilling holes in the top of milk cartons, the hole fragments cut by the drilling tool tend to stick to the cutting tool and get stuck in the hole, which seriously affects subsequent drilling and causes low work efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a punching tool for the teardrop opening of milk packaging boxes. This tool can solve the problem that in the prior art, when punching the opening at the top of milk packaging boxes, the hole fragments cut by the punching tool are easy to stick to the cutter and get stuck in the hole, which is not easy to remove and seriously affects subsequent punching, resulting in low work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A punching tool for the teardrop-shaped opening of a milk packaging carton includes an upper punch block and a lower punch block. The upper punch block has a teardrop-shaped platform at its center on its bottom surface, and a cutter is provided at the edge of the bottom surface of the teardrop-shaped platform. A set screw hole is formed in the center of the teardrop-shaped platform, and a set screw is installed inside the set screw hole. The bottom surface of the set screw is 0.3mm-0.6mm higher than the platform surface of the teardrop-shaped platform. The lower punch block has a teardrop-shaped opening at its center on its top surface, which cooperates with the teardrop-shaped platform to achieve punching. The lower punch block also has a circular hole at its center on its bottom surface, which communicates with the teardrop-shaped opening. The diameter of the circular hole is larger than the diameter of the circle surrounding the teardrop-shaped opening.

[0006] Preferably, the width of the water droplet hole is 14.6 mm, the height is 12.06 mm, and the diameter of the circular hole is 22 mm.

[0007] Preferably, the four corners of the upper and lower punch blocks are rounded.

[0008] Preferably, both the upper and lower die blocks are provided with bolt holes, and both the upper and lower die blocks are fixedly connected to the die-casting machine by bolts.

[0009] Preferably, the cutting edge of the cutter has a serrated structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a set screw on the teardrop-shaped platform, and the bottom surface of the set screw is 0.3mm-0.6mm higher than the platform surface of the teardrop-shaped platform, the protruding set screw will exert a downward force on the cut hole fragments during drilling, causing them to separate from the cutter; at the same time, a circular hole is set below the teardrop hole to facilitate the hole fragments to fall downward, ensuring that subsequent drilling is carried out smoothly and improving work efficiency. Attached Figure Description

[0011] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this utility model. For those skilled in the art, other drawings can be obtained based on these drawings.

[0013] Explanation of reference numerals in the attached figures: 1-Upper punch stopper block, 2-Lower punch stopper block, 3-Teardrop mold platform, 4-Ejector screw, 5-Teardrop hole, 6-Circular hole, 7-Bolt hole. Detailed Implementation

[0014] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments.

[0015] like Figures 1 to 3As shown, this utility model discloses a punching tool for the teardrop-shaped opening of a milk packaging carton, including an upper punch block 1 and a lower punch block 2. The four corners of both the upper punch block 1 and the lower punch block 2 are rounded, eliminating sharp corners and improving the product's appearance while preventing injury to the operator. A teardrop-shaped platform 3 is integrally formed at the center of the bottom surface of the upper punch block 1. A cutter is provided on the edge of the bottom surface of the teardrop-shaped platform 3, and the cutter's blade has a serrated structure. A set screw hole is opened in the middle of the teardrop-shaped platform 3, and a set screw 4 is installed inside the set screw hole. The bottom surface of the set screw 4 is 0.5mm higher than the platform surface of the teardrop-shaped platform 3. By setting the set screw 4 on the teardrop-shaped platform 3, with the bottom surface of the set screw 4 being 0.5mm higher than the platform surface of the teardrop-shaped platform 3, during punching, the protruding set screw 4 applies a downward force to the cut-off hole fragments, causing them to separate from the cutter. The lower punch block 2 has a teardrop hole 5 at the center of its top surface, which cooperates with the teardrop mold 3 to achieve drilling. The lower punch block 2 has a circular hole 6 at the center of its bottom surface, which is connected to the teardrop hole 5. The diameter of the circular hole 6 is larger than the diameter of the circle formed around the teardrop hole 5. In this embodiment, the teardrop hole 5 has a width of 14.6 mm and a height of 12.06 mm, and the circular hole 6 has a diameter of 22 mm. The size of the circular hole 6 is larger than that of the teardrop hole 5, which facilitates the downward fall of the hole fragments and ensures that subsequent drilling is carried out smoothly.

[0016] Both the upper die block 1 and the lower die block 2 are provided with bolt holes 7, and both the upper die block 1 and the lower die block 2 are fixedly connected to the die punching machine by bolts.

[0017] In use, the upper die block 1 and the lower die block 2 are fixed to the punching machine with bolts. The milk carton to be punched is placed on the lower die block 2 and fixed. The upper die block 1 moves downward, so that the teardrop-shaped platform 3 enters the teardrop hole 5. The cutter cuts out the hole fragments. Under the combined action of the set screw 4 and the circular hole 6, the hole fragments fall downward. After punching is completed, the upper die block 1 moves upward, and the next carton can be punched.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and application concept of the present utility model, should be included within the protection scope of the present utility model.
