Description

Technical Field

[0001] This utility model relates to a punch, and more particularly to a punch for EVA or silicone packaging. Background Technology

[0002] Traditional hole punchers have several drawbacks: solid needles easily tear or leave rough edges when piercing soft materials; waste material gets trapped inside the hole, requiring secondary cleaning and resulting in low efficiency; and the handle structure is not ergonomic, leading to fatigue during continuous use. Currently, there are no hole punchers specifically designed for EVA or silicone bags, limiting the customization options available for bag surfaces. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a punch for EVA or silicone bags, which can punch holes on the surface of EVA or silicone bags with good punching quality and realize automatic and continuous discharge of waste.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a punch for EVA or silicone packaging. The punch is T-shaped and includes a handle and a needle body connected to the handle. The needle body includes a cylindrical needle rod and a conical needle tip. The lower end of the cylindrical needle rod is connected to the conical needle tip, and the upper end of the cylindrical needle rod is connected to the handle. The conical needle tip is a hollow structure with a cutting hole inside. The side of the cylindrical needle rod has a discharge groove communicating with the cutting hole. The end of the discharge groove away from the conical needle tip has a slope. The principle of this utility model is as follows: When punching, a plastic pad is placed on the back of the punching area. The handle is held and pressed vertically. The conical needle tip pierces the EVA material, and the cut waste enters the cutting hole. The waste moves upward along the discharge groove. After contacting the slope, the waste pops out. If the waste is stuck in the discharge groove, it can be easily removed using a tool.

[0005] As an improvement, the handle is a plastic handle.

[0006] As an improvement, the handle is crescent-shaped, with its convex arc surface facing upwards and its concave arc surface facing downwards, and is connected to the needle body.

[0007] As an improvement, a protruding connecting part is provided at the middle position of the concave arc surface of the handle, and the upper end of the cylindrical needle bar is connected to the connecting part.

[0008] As an improvement, the punch is used in conjunction with a plastic gasket, the edge of which is provided with a cutting groove, and a material-inserting part is formed on the plastic gasket in the area outside the cutting groove, the material-inserting part being able to extend into the cutting hole.

[0009] The beneficial effects of this utility model compared with the prior art are: The conical needle allows for progressive puncture, preventing excessive material deformation; waste material automatically slides out along the inclined surface after entering the discharge chute, improving drilling efficiency; the crescent-shaped handle distributes pressure, reducing operating force.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, a punch for EVA or silicone packaging is disclosed. The punch is T-shaped and includes a handle 1 and a needle body connected to the handle 1. The needle body includes a cylindrical needle bar 2 and a conical needle tip 3. The lower end of the cylindrical needle bar 2 is connected to the conical needle tip 3, and the upper end of the cylindrical needle bar 2 is connected to the handle 1. The conical needle tip 3 is hollow and has a cutting hole inside. The conical needle tip 3 allows for progressive puncture, avoiding excessive deformation of the material. The side of the cylindrical needle bar 2 is provided with a discharge groove 4 that communicates with the cutting hole. The end of the discharge groove 4 away from the conical needle tip 3 has an inclined surface. After waste material enters the discharge groove 4, it automatically slides out along the inclined surface, improving punching efficiency. The handle 1 is made of plastic, which reduces the weight of the punch and allows for the printing of logos and anti-slip stripes on its surface. The handle 1 is crescent-shaped, with its convex surface facing upwards and its concave surface facing downwards. This crescent shape distributes pressure, reducing the effort required to operate. A protruding connecting part 5 is located in the middle of the concave surface of the handle 1. The upper end of the cylindrical needle bar 2 connects to the connecting part 5, and this connection can be achieved through in-mold injection molding, enhancing the reliability of the connection. Figure 4 As shown, the punching device cooperates with the plastic gasket 7. The edge of the plastic gasket 7 is provided with a punching groove. A material-push-out part 71 is formed on the plastic gasket 7 in the area outside the punching groove. The material-push-out part 71 can extend into the cutting hole.

[0017] The principle of this utility model is as follows: Figure 2 , 3As shown, during punching, the plastic pad 7 is placed on the back of the punching area, and the handle 1 is held and pressed vertically. The conical needle 3 pierces the EVA material 6, and the cut waste material 8 enters the cutting hole. The waste material 8 moves upward along the discharge groove 4, and pops out after contacting the inclined surface; as shown. Figure 5 As shown, when waste material 8 cannot be discharged in time, the material ejector 71 on the plastic gasket 7 can be inserted into the cutting hole to discharge the waste material 8. After the surface of the bag is perforated, different ornaments can be installed at the perforated points to achieve bag customization.
