[0037] As Figure 1 、 Figure 2 shown, the present utility model provides a profiling punch device for manufacturing a package, including:

[0038] An outer holding jaw structure 1 for clamping and transferring a base 3; the base 3 is the main component to be installed and needs to be installed.

[0039] A soft profiling punch 2 for pressing the base 3, the soft profiling punch being slidably disposed inside the outer holding jaw structure; the soft profiling punch 2 is made of a soft material, and the soft material refers to a material that is soft, elastic, expansible, and conductive, such as rubber, foam plastic, thermoplastic polyurethane, etc. In contrast, the hard material refers to a material that is hard, not easily bendable, wear-resistant, and has strong compressive strength, such as metal, ceramic, glass, etc. The soft profiling punch 2 can effectively buffer the pressing force of the punch on the base 3 and reduce the friction scratches generated during pressing.

[0040] The press-in driving structure connected to the soft profiling indenter 2 has at least two strokes. Among them, in at least one stroke, the soft profiling indenter 2 is pressed to install the base 3 into the pre-pressed puncture piece 5, and in at least one stroke, the base 3 and the puncture piece 5 are finally pressed.

[0041] The utility model solves the problems existing in the current situation where a circular stainless steel indenter is press-fitted into a puncture piece with a good one-time positioning at once. There are problems such as the shape mismatch between the indenter and the base, the excessive one-time press-in pressure causing damage and deformation or crushing of the weak area of the base, or causing the puncture piece to puncture the weak area of the base, resulting in the premature leakage of the filling material in the overall fresh-keeping lid before it is opened, with a high overall defective rate and low production efficiency.

[0042] The utility model uses a soft profiling indenter 2 to press the base 3 tightly, which can effectively buffer the pressing force of the indenter on the base 3 and reduce the friction scratches generated during pressing. Moreover, the pressing of the soft profiling indenter 2 includes at least two press-in processes, avoiding the damage and deformation or crushing caused by excessive one-time press-in pressure. Pressing in multiple times effectively ensures the pressing effect, avoids the problem of premature material leakage, reduces the overall defective rate, and improves production efficiency.

[0043] As Figure 2 shown, the utility model further includes an annular workpiece 4 for loading the positioned puncture piece 5 and for the subsequent transfer after the base 3 is equipped.

[0044] Further, as Figure 1 、 Figure 3 shown, a weak area 31 (prior art) is provided on the upper part of the base 3. The cross-section where the weak area is located on the base 3 is the first cross-section, the outer contour shape of the first cross-section is a square, the side length of the first cross-section is L1, the cross-section of the soft profiling indenter 2 is the second cross-section, the outer contour of the second cross-section is a square, and the side length of the second cross-section is L0. To ensure avoiding the deformation or crushing of the weak area 31, 0.75L1 ≤ L0 ≤ 0.9L1 is required.

[0045] Further, as Figure 1 、 Figure 3 shown, the diameter of the weak area is D1, and a hollowed-out hole groove 21 is provided at the position corresponding to the weak area on the soft profiling indenter 2. The diameter of the hollowed-out hole groove 21 is D0. To ensure avoiding the deformation or crushing of the weak area 31, 1.1D1 ≤ D° ≤ 1.5D1 is required.

[0046] Further, the soft profiling indenter 2 is a polyurethane profiling indenter. The polyurethane profiling indenter can be replaced by other profiling indenters with soft materials to meet the buffering and protection functions when pressing the base 3 tightly.

[0047] Further, as Figure 1 、 Figure 2As shown in the figure, the external holding jaw structure 1 includes a jaw seat 11 and two oppositely arranged jaws 12. A first guide groove 13 is provided inwardly at the bottom end of the jaw seat 11, and each jaw 12 can move along the first guide groove 13 under the drive of a jaw drive structure (not shown in the figure); Oppositely arranged jaw hook grooves are provided on the two jaws 12, and a clamping space for the base is formed between the two jaw hook grooves; The soft profiling indenter 2 can move up and down within the clamping space.

[0048] Further, as Figure 1 shown, in order to more stably clamp the outer ring surface of the base 3, arc-shaped notches 14 are oppositely arranged on the adjacent side walls of the two jaws 12.

[0049] Further, as Figure 1 shown, a guide post 22 is connected to the soft profiling indenter 2, and a second guide groove is provided on the jaw seat 11. The guide post 22 slidably penetrates through the second guide groove.

[0050] To ensure circumferential positioning, the cross-sections of the guide post 22 and the second guide groove are rectangular.

[0051] Further, the pressing drive structure is a cylinder with two strokes, and this structure is not shown in the figure.

[0052] Further, all components of the present utility model comply with food hygiene design. The metal materials in contact with the product are made of 304 and 316 stainless steels, and the sealing materials are made of EPDM, silicone, and Teflon, greatly improving the hygiene and safety of food.

[0053] At the same time, the present utility model uses a PLC for full-automatic control (pressing drive structure, external holding jaw structure), improving the automation, stability, and reliability of the system.

[0054] The usage process of the profiling indenter device for manufacturing packaging of the present utility model is as follows:

[0055] As Figure 2 shown, the external holding jaw structure 1 moves the positioned base 3 to the designated position of the annular workpiece 4 by grasping. A puncture member 5 is positioned on the annular workpiece 4. The soft profiling indenter 2 (polyurethane profiling indenter) is driven by a cylinder with two strokes to press down the base 3. The first stroke of the cylinder is used for pre-pressing during installation, and after the pre-pressing is completed, the second stroke is used for final pressing to complete the assembly of the base 3 and the puncture member 5, improving the problems encountered in the above-mentioned one-time pressing.

[0056] As described above, the profiling indenter device for manufacturing packaging of the present utility model has the following beneficial effects:

[0057] The present utility model solves the problems that in the current situation where a circular stainless steel pressing head is press-fitted into a puncturing member that has been positioned once, there are issues such as the shape mismatch between the pressing head and the base, excessive pressure during a single press-fitting causing damage or deformation due to crushing in the weak area of the base, or causing the puncturing member to puncture the weak area of the base, resulting in premature leakage of the filling material inside the overall freshness-keeping lid before it is opened, with a high overall defective rate and low production efficiency.

[0058] The present utility model uses a soft profiling pressing head to press against the base, which can effectively buffer the pressing force of the pressing head on the base and reduce the friction scratches generated during pressing; moreover, the pressing of the soft profiling pressing head includes at least two press-fitting processes, avoiding damage or deformation due to excessive pressure during a single press-fitting, ensuring the pressing effect through multiple pressings, avoiding the problem of premature leakage of materials, reducing the overall defective rate, and improving production efficiency.

[0059] The above are only illustrative specific embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present utility model shall fall within the scope of protection of the present utility model.
