Description

Technical Field

[0001] This utility model relates to an aluminum buckle crimping tool specifically for ink bags, belonging to the technical field of ink bag crimping equipment. Background Technology

[0002] As containers for holding ink-like fluids, the sealing performance of ink bags directly affects the storage stability and safety of their contents. The aluminum buckle on the ink bag is the core component that achieves this sealing function. It is usually a ring-shaped metal structure that needs to be tightly snapped onto the liquid outlet of the ink bag through a crimping process to form a leak-proof and contamination-proof seal. Its dimensional accuracy and deformation uniformity directly determine the sealing quality.

[0003] However, current technologies have significant limitations in the ink bag aluminum buckle crimping process, making it difficult to meet actual production needs. On one hand, the commonly available claw-type crimping machines have obvious compatibility issues. These machines were originally designed primarily for pharmaceutical vials, with their crimping mechanism's dimensions and force distribution adapted to the 13mm outer diameter glass vial port. However, ink bags, being plastic containers, have fundamentally different physical properties at their ports compared to glass—the elastic deformation coefficient of plastic is much higher than that of glass, and the outer diameter of the ink bag aluminum buckle typically does not conform to the 13mm standard. This makes it difficult for claw-type crimping machines to accurately match the size and material characteristics of the ink bag port, easily leading to uneven crimping force and poor engagement between the aluminum buckle and the plastic port, severely affecting the sealing effect.

[0004] On the other hand, other manual capping tools on the market are inadequate for handling small-sized aluminum clips. Ink bag clips are designed to fit miniature ink outlet ports, and their outer diameter is typically less than 8mm. However, existing manual tools have insufficient precision in their capping dies and rely on manual application of force, making it difficult to guarantee pressure stability and uniformity during the capping process. In practice, this can cause the aluminum clip to fail to undergo proper plastic deformation along the preset trajectory. Either insufficient force results in incomplete deformation and a loose seal, or excessive localized force causes destructive damage such as cracking and wrinkling at the edges of the clip. This not only directly leads to seal failure but may also generate metal debris that contaminates the contents of the ink bag, creating serious quality risks.

[0005] In summary, in the existing technology, claw-type capping machines cannot be applied to the capping of aluminum buckles for plastic ink bags due to size and material compatibility issues, while manual capping tools suffer from abnormal deformation and structural damage when processing small-sized aluminum buckles. Both of these factors contribute to the low efficiency and low yield rate of the ink bag aluminum buckle capping process, becoming a key technical bottleneck restricting the upgrading of ink bag packaging technology. Utility Model Content

[0006] To solve the above problems, this utility model provides a special aluminum snap-on capping tool for ink bags, comprising:

[0007] The base includes a base plate and a vertical plate disposed on the base plate, wherein the vertical plate has a through hole;

[0008] A stamping device is fixed to the base, and the stamping head of the stamping device can pass through the through hole;

[0029] Example 1

[0030] like Figures 1-5 As shown, this utility model provides a tooling for aluminum snap-on caps specifically for ink bags, including a base 1, a stamping device 2 and a clamping assembly 3 mounted on the base 1, specifically:

[0031] The base 1 includes a base plate and a vertical plate 11 disposed on the base plate. The vertical plate 11 has a through hole for the punching head 23. An electrical box is disposed on one side of the base 1 for power supply.

[0032] The stamping device 2 is fixed to the base 1. The stamping device includes a stamping cylinder fixed to the base plate and a stamping head connector and a stamping head connected in sequence to the stamping cylinder. The stamping head 23 of the stamping device 2 can pass through the through hole.

[0033] In some embodiments, the stamping head 23 has a cylindrical structure, and a contour groove 231 is provided at one end of the stamping head 23 near the clamp assembly 3. The contour groove 231 can fit the micro-convex surface at the end of the aluminum buckle 5, so as to apply pressure evenly to the aluminum buckle 5.

[0034] The clamp assembly 3 includes a lower clamp 32 fixed to the base plate and an upper clamp 31 movably connected to the upright plate 11. The lower clamp 32 and the upper clamp 31 are respectively provided with two semi-circular notches facing each other. Further, the upper clamp 31 is an inverted T-shaped structure with a crescent-shaped notch at the bottom, and the lower clamp 32 is a T-shaped structure with a semi-circular notch at the top.

[0035] When the upper chuck 31 moves to engage with the lower chuck 32, the two semi-circular notches close together to form a contoured cavity structure 9. The contoured cavity structure 9 can cooperate with the aluminum buckle 5 that fixes the ink nozzle 4, playing a positioning role in the stamping process and preventing the aluminum buckle 5 from floating during the stamping process.

[0036] Preferably, the circular end face of the contoured cavity structure 9 is concentrically positioned with the stamping head 2, which facilitates the stamping head 2 to apply pressure to the aluminum buckle 5 accurately and evenly.

[0037] Furthermore, the two semi-circular notch structures are identical, and their surfaces each include a primary curved surface 6 located near the stamping device 2 and a secondary curved surface 7 located away from the stamping device 2. The transition connection between the primary curved surface 6 and the secondary curved surface 7 forms a limiting surface 8. The shape of the primary curved surface 6 is adapted to the outer shape of the aluminum buckle 5. When the aluminum buckle 5 is engaged with the contoured cavity structure 9, the aluminum buckle 5 is located exactly within the space formed by the primary curved surfaces 6 of the upper clamp 31 and the lower clamp 32. The limiting surface 8 can play a proximal limiting role, preventing the aluminum buckle 5 from being squeezed out radially from the contoured cavity structure 9 after being pressed, thus ensuring the safety of the equipment.

[0038] In some embodiments, preferably, a transition portion is provided between the limiting surface 8 and the primary curved surface 6 and the secondary curved surface 7 to reduce wear on the near end of the aluminum buckle 5 caused by friction.

[0039] In some embodiments, the clamping assembly 3 further includes a clamping cylinder 33 fixed to the upright plate 11. The clamping cylinder 33 is connected to the upper chuck 31, and the upper chuck 31 is moved vertically by the clamping cylinder 33, thereby controlling the formation of the contoured cavity structure 9. Furthermore, the lower chuck 32 is fixed to the base plate by a chuck seat 34, improving the stability of the lower chuck 32.

[0040] like Figure 6 As shown, the operation method of this utility model is as follows:

[0041] Step 1: Place the assembled ink nozzle 4 on the lower chuck 3, and place the aluminum clip 5 on the first-level curved surface 6 of the lower chuck 3.

[0042] Step Two: Control the upper chuck 4 to press down, cooperating with the lower chuck 3 to form a sealed, contoured cavity structure 9. The aluminum buckle 5 can only move slightly back and forth within the cavity, and its maximum stroke at the proximal end is limited by the limiting surface 8. At this time, from a top-down perspective... Figure 6 The initial state in.

[0043] Step 3: Under the drive of the stamping cylinder 21, the stamping head 23 pushes the aluminum buckle 5, and the aluminum buckle 6 gradually moves towards the near end. At this time, from a top-down perspective... Figure 6 The extrusion positioning state.

[0044] Step Four: As the space of the contoured cavity structure 9 gradually tightens, the stamping head 23 is further advanced. The external shape of the aluminum buckle 6 gradually transforms into the same structure as the contoured cavity structure 9. Thanks to the contoured design of the stamping head 23 and the end of the aluminum buckle 5, under the same pressure, only a small amount of deformation occurs at the end of the aluminum buckle 5, with all deformation concentrated at the tail of the aluminum buckle 5. At this time, from a top-down perspective... Figure 6 The yield deformation state in the process.

[0045] Step 5: After stamping is completed, open the upper chuck 31 and remove the ink nozzle 4.

[0046] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
