Description

Technical Field

[0001] This utility model belongs to the field of packaging box defoaming technology, specifically relating to a defoaming device for irregularly shaped box opening strips. Background Technology

[0002] When forming a premium wine box with a mouth strip, the face paper and industrial cardboard must first be positioned and laminated by hand, the top edge of the box is wrapped, and then the mouth strip is pasted in. Afterwards, a scraper is used to manually press and shape the face paper and mouth strip. Inconsistent manual pressing techniques result in uneven pressure, failing to ensure full pressure on the face paper and creating scratches, which can lead to poor adhesion and quality issues. Furthermore, because the mouth strip is inside the box, applying pressure is inconvenient, resulting in low production efficiency.

[0003] The applicant's prior utility model patent application, "Device for Defoaming After Assembly of Packaging Box Tape and Lid", with publication number CN212386094U, discloses a defoaming device applicable to cuboid packaging boxes.

[0032] The following embodiments are further elaborated based on the above solutions.

[0033] Example

[0034] Please refer to Figure 1-6 This embodiment provides a bubble removal device for the mouth strip of an irregularly shaped box, which is suitable for hexagonal prism irregularly shaped boxes with a hexagonal cross-section. The irregularly shaped box is a box body with one end open and the other end closed, and the mouth strip is pasted on the inner wall of the opening of the irregularly shaped box. The bubble removal device is used to squeeze the mouth strip to press the mouth strip and the irregularly shaped box together, thereby removing the air bubbles between the mouth strip and the irregularly shaped box and ensuring that the mouth strip is firmly pasted.

[0035] Specifically, the defoaming device includes an inner mold and an outer mold 14. The inner mold and the outer mold 14 cooperate to press the mouth strip and the irregularly shaped box together to remove bubbles. The inner mold includes a base 11, a bottom edge defoaming assembly 12, and a pair of side defoaming molds 13. The base 11 of the inner mold is fixed on the mold frame of the platform. The base 11 includes a Teflon body 111 and a metal connecting plate 112. The metal connecting plate 112 is fixed on the Teflon body 111. The two side defoaming molds 13 are fixed on the metal connecting plate 112 and are symmetrically distributed on both sides of the bottom edge defoaming assembly 12. The side defoaming molds 13 have a first defoaming surface 131 and a second defoaming surface 132 that respectively fit with the mouth strip of the irregularly shaped box. In this embodiment, the side defoaming molds 13 are triangular. The side-mounted bubble molding die 13 is also provided with a guide ramp 133 and a positioning flange 134. When the irregularly shaped box is fitted onto the side-mounted bubble molding die 13, the guide ramp 133 guides the irregularly shaped box to smoothly fit onto the side-mounted bubble molding die 13, while the positioning flange 134 stops the irregularly shaped box from continuing to move forward, thus playing a positioning role. It should be noted that the side-mounted bubble molding die 13 is a Teflon body 111 piece.

[0036] The outer mold 14 is paired with the side bubble pressing mold 13. The number of outer molds 14 is the same as the number of side bubble pressing molds 13, that is, there are also two outer molds 14. The outer molds 14 correspond one-to-one with the side bubble pressing molds 13. The outer mold 14 has a third bubble pressing surface 141 and a fourth bubble pressing surface 142. The third bubble pressing surface 141 matches the first bubble pressing surface 131, and the fourth bubble pressing surface 142 matches the second bubble pressing surface 132. In addition, the platform is also equipped with an outer mold 14 driving assembly. The outer mold 14 driving assembly can be a linear drive mechanism such as a cylinder, hydraulic cylinder or electric push rod. In this embodiment, the outer mold 14 driving assembly adopts an outer mold 14 cylinder. The outer mold 14 is connected to the outer mold 14 cylinder. When the irregular box is placed on the side bubble pressing mold 13 of the inner mold, the outer mold 14 cylinder extends and drives the outer mold 14 to move closer to the side bubble pressing mold 13. The outer mold 14 and the side bubble pressing mold 13 are used to squeeze the strips on both sides of the irregular box to achieve bubble removal.

[0037] It should be noted that the third foam pressing surface 141 and the fourth foam pressing surface 142 of the outer mold 14 are both covered with a buffer layer 143. The buffer layer 143 can be made of a certain hardness and a certain rubber pad or other materials to prevent the outer mold 14 from leaving indentations on the surface of the irregular box during the extrusion and defoaming process.

[0038] In this embodiment, the bottom edge bubble-pressing assembly 12 includes a bottom edge drive component, a connecting block 122, and a liftable bottom edge bubble-pressing block 123. The bottom edge drive component is fixed on the mold frame. The bottom edge drive assembly can adopt a linear drive mechanism such as a cylinder, hydraulic cylinder, or electric push rod. In this embodiment, the bottom edge drive assembly adopts a bottom edge cylinder 121. The connecting block 122 is connected to the bottom edge cylinder 121 and the bottom edge bubble-pressing block 123. The bottom edge cylinder 121 drives the bottom edge bubble-pressing block 123 to rise and fall through the connecting block 122. In the initial state, the bottom edge cylinder 121 is in a retracted state. After the irregular box is fitted into the side bubble-pressing mold 13, the bottom edge cylinder 121 extends, causing the bottom edge bubble-pressing block 123 to move downward and press down on the lip strip to remove bubbles.

[0039] In this embodiment, the base 11 is provided with a clearance groove 111 to avoid the connecting block 122, so as to facilitate the up and down movement of the connecting block 122.

[0040] This utility model employs a side bubble-pressing mold 13 similar to that of an irregularly shaped box, and a liftable bottom bubble-pressing component 12. The side bubble-pressing mold 13 and the outer mold 14 work together to squeeze and remove bubbles from the side opening of the irregularly shaped box, and the bottom bubble-pressing component 12 squeezes and removes bubbles from the bottom opening of the irregularly shaped box, thereby achieving bubble removal from the opening of a packaging box with a hexagonal cross-section.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
