Description

Technical Field

[0001] This utility model belongs to the field of packaging bag processing technology, specifically relating to an inner rounded corner hot stamping knife for a bag making machine. Background Technology

[0002] Bag-in-bag packaging is a common form of packaging widely used in food, beverages, and pharmaceuticals. In the processing of bag-in-bags, rounded corner heatsinks are widely used for sealing and cutting. These heatsinks are heated at high temperatures and then applied to the sealing and cutting operations of the bag-in-bag. This rounds the outer corners of the bag-in-bag, preventing the sharp edges from causing injury to the user. However, the inner corners remain right angles, and the sharp points of these right angles bear greater pressure and are prone to tearing. Currently, there are no bag-in-bags with rounded inner corners, nor are there corresponding heatsinks for this purpose. Utility Model Content

[0003] This utility model provides an inner rounded corner hot stamping knife for a bag making machine, which solves the shortcomings described in the background art. By hot stamping the raw materials with multiple raised hot stamping knives, a bag body with inner rounded corners can be made, which increases the internal capacity of the bag body, reduces the pressure on the four corners of the bag, and improves the bonding strength of the four corners of the bag.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An inner rounded corner hot stamping blade for a bag-making machine includes a hot stamping blade aluminum substrate. At least two raised hot stamping blades are located on the working end face of the substrate, with a gap between adjacent raised hot stamping blades. Each raised hot stamping blade has an arc-shaped segment. The gap is to allow space for sealing the bag body in areas other than the corners. The bag edges are hot-stamped at this gap, corresponding to the edges of two connected bags. The position created by the arc-shaped segment corresponds to the inner corner of the bag, and the opposite side of the arc-shaped segment corresponds to the outer corner of the bag. The raised hot stamping blades directly process the corners of the bag, and the inner corners are rounded, increasing the distance between the inner and outer corners, reducing the pressure on the inner corners of the bag, and improving the pressure-bearing capacity of the corners.

[0006] In a preferred embodiment of this invention, the working end face of the raised hot plate is a closed plane formed by the splicing of an arc-shaped segment, a first edge segment, and a second edge segment; the arc-shaped segment and the first edge segment are smoothly connected at their junctions, and the arc-shaped segment and the second edge segment are also smoothly connected at their junctions. The smooth connection can be achieved by rounding corners, and the center of the rounded corner is not on the same side as the center of the arc-shaped segment.

[0007] In a preferred embodiment of this utility model, the first edge segment and the second edge segment are arranged perpendicularly. The first edge segment and the second edge segment are straight segments, and the intersection point can be a 90° angle or an arc. The straight segment is the inner edge of the hot-stamped edge of the bag body.

[0008] In a preferred embodiment of this invention, a small arc-shaped segment is provided at the junction of the first edge segment and the second edge segment. The small arc-shaped segment ensures that after the raised hot iron is applied, both the inner and outer sides of the corner are arc-shaped, rather than sharp right angles, thus enhancing the bonding strength of the corner.

[0009] In a preferred embodiment of this invention, four raised heat-sealing blades are arranged in a ring, with the center of the ring being the center of the working end face of the aluminum substrate of the heat-sealing blade; and the arc-shaped segment of each raised heat-sealing blade faces outward. This allows for the processing of one corner of four bags at a time, improving the processing efficiency of the bags.

[0010] As a preferred embodiment of this utility model, the aluminum substrate of the hot iron is adjustablely mounted on the slide rail. The position of the aluminum substrate of the hot iron can be changed by sliding on the slide rail. After the position is adjusted, it can be fixed on the slide rail for hot ironing of the corners of the bag. The resulting corners have arc-shaped inner angles and arc-shaped outer angles.

[0011] In a preferred embodiment of this invention, the aluminum substrate of the hot iron has a T-shaped mounting groove on its end face opposite to the working end face, and a fixing hole on its side end face that communicates with the T-shaped mounting groove. A T-shaped protrusion is provided on the slide rail, and the T-shaped protrusion is fitted into the T-shaped mounting groove. The aluminum substrate of the hot iron slides along the T-shaped protrusion to a suitable position, and a locking bolt passes through the fixing hole and abuts against the T-shaped protrusion. Multiple aluminum substrates of the hot iron can be installed on one slide rail, with the appropriate number determined according to the processing dimensions of the bag material. The T-shaped mounting groove is fitted from the side of the T-shaped protrusion, so that the T-shaped protrusion is engaged within the T-shaped mounting groove. The aluminum substrate of the hot iron can slide along the T-shaped protrusion through the T-shaped mounting groove. After sliding to a suitable position, it is tightened with a locking bolt. A symmetrical arrangement on both sides is preferred.

[0012] In a preferred embodiment of this utility model, the slide rail is provided with mounting holes. The mounting holes are perpendicular to the direction of the fixing holes. The mounting holes are provided to install the slide rail onto the processing equipment. The aluminum base of the hot knife mounted on it can be assembled and fixed later, or it can be assembled and fixed first and then the slide rail is fixed. The slide rail is made of brass.

[0013] In a preferred embodiment of this invention, a copper plate is disposed below the aluminum substrate of the hot iron, with the upper surface of the copper plate serving as the reference plane for the raised hot iron. During operation, the copper plate moves relative to the aluminum substrate of the hot iron. The slide rail and the aluminum substrate of the hot iron mounted on it can move closer to or further away from the copper plate, thus hot ironing together the edges and corners of the bag material passing between the copper plate and the aluminum substrate of the hot iron.

[0014] This invention uses multiple raised hot stamping blades on an aluminum substrate to process the corners of a bag individually. The arc-shaped segment of the raised hot stamping blade corresponds to the inner corner of a corner. The inner corner is arc-shaped, which reduces the pressure on the inner corner after the bag is formed, increases the distance between the inner and outer corners, improves the hot stamping strength of the corners, and can process the corners of multiple bags at once, thus improving processing efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] A rounded-corner hot stamping blade for a bag-making machine includes a hot stamping blade aluminum substrate 1, such as... Figure 1-3 As shown, there are at least two protruding hot knives 2 on the working end face of the aluminum substrate 1 of the hot knife. This embodiment uses four as an example for demonstration. Figure 2As shown, four raised hot iron blades 2 are arranged in a ring, and the center of the ring is the center of the working end face of the hot iron blade aluminum base 1; and a gap 3 is reserved between adjacent raised hot iron blades 2. The gap is to make room for the sealing position of the bag body in areas other than the corners. The edge of the bag body will be hot ironed at this gap, corresponding to the edge of two connected bags.

[0026] Each raised hot plate 2 has a working end face that is a closed plane formed by the combination of an arc-shaped segment 21, a first edge segment 22, and a second edge segment 23. The arc-shaped segment 21 and the first edge segment 22 are smoothly connected at their junctions, and the arc-shaped segment 21 and the second edge segment 23 are also smoothly connected at their junctions. The smooth connection can be achieved by rounding the corners, and the center of the rounded corner is not on the same side as the center of the arc-shaped segment.

[0027] The first edge segment 22 and the second edge segment 23 are set perpendicularly. The first edge segment and the second edge segment are straight segments, and the intersection can be at a 90° angle or an arc. The straight segment is the inner edge of the ironing edge of the bag body. In this embodiment, a small arc segment 24 is preferably provided at the junction of the first edge segment 22 and the second edge segment 23. The small arc segment makes the inner and outer sides of the corners arc-shaped after the raised ironing knife is ironed, rather than a right angle, thus enhancing the ironing strength of the corners.

[0028] Each raised heatsink 2 has an outward-facing arc segment 21, processing one corner of four bags at a time, thus improving processing efficiency. The position created by the arc segment corresponds to the inner corner of the bag, while the opposite side of the arc segment corresponds to the outer corner of the bag. The raised heatsink 2 directly processes the corners of the bag, and the inner corners are rounded, increasing the distance between the inner and outer corners, reducing the pressure on the inner corners of the bag, and improving the pressure resistance of the corners.

[0029] In use, the aluminum base 1 of the hot iron is adjustablely mounted on the slide rail 4. The position of the aluminum base can be changed by sliding it on the slide rail. After adjustment, it can be fixed to the slide rail for ironing the corners of the bag. The resulting corners have rounded inner and outer angles. Specifically, the aluminum base 1 has a T-shaped mounting groove 11 on its end face opposite the working end face, and a fixing hole 12 on its side end face, which communicates with the T-shaped mounting groove 11. Figure 4 and 5 As shown, the slide rail 4 is provided with a T-shaped protrusion 41, which is assembled in the T-shaped mounting groove 11. The hot knife aluminum base 1 slides along the T-shaped protrusion 41 to a suitable position, and the locking bolt passes through the fixing hole 12 and abuts against the T-shaped protrusion 41.

[0030] Multiple hot iron aluminum bases can be installed on a slide rail. The appropriate number is set according to the processing size of the bag material. The T-shaped mounting groove 11 is assembled from the side of the T-shaped protrusion 41, so that the T-shaped protrusion 41 is locked in the T-shaped mounting groove 11. The hot iron aluminum base 1 can slide along the T-shaped protrusion 41 through the T-shaped mounting groove 11. After sliding to the appropriate position, it is tightened with locking bolts. It is preferred to adopt a symmetrical arrangement on both sides.

[0031] To facilitate the installation of the slide rail onto the processing equipment, slide rail 4 is provided with mounting holes, and the slide rail is made of brass. The mounting holes are perpendicular to the mounting holes 12; the mounting holes are provided so that the aluminum base 1 of the hot iron can be assembled and fixed later, or assembled and fixed first and then the slide rail can be fixed.

[0032] When heat-sealing the bag body, a heat-sealing reference plane is required. In this embodiment, a copper plate 5 is set below the aluminum substrate 1 of the heat-sealing blade, such as... Figure 6 and 7 As shown, the upper surface of the copper plate 5 serves as the reference plane for the raised hot iron 2; in the working state, the copper plate 5 moves relative to the aluminum substrate 1 of the hot iron. The slide rail and the aluminum substrate 1 of the hot iron mounted on it can be installed on the lifting equipment, close to and away from the copper plate, and the edges of the bag material are hot ironed together between the copper plate and the aluminum substrate 1 of the hot iron.
