[0037] This application provides a defoaming machine for the mouth strip of an irregularly shaped box, including a platform 1 and a mold frame 2 disposed on the platform 1, as well as a box-picking robot and a box-pushing device disposed on the platform 1. The irregularly shaped box has a hexagonal cross-section. The defoaming machine also includes a defoaming device 3 adapted to the irregularly shaped box. The defoaming device 3 includes an inner mold and an outer mold 34. The inner mold and the outer mold 34 cooperate to press the mouth strip and the irregularly shaped box together to remove bubbles.

[0038] The following embodiments are further elaborated based on the above solutions.

[0039] Example

[0040] Please refer to Figure 1-8 This embodiment provides a defoaming machine for irregularly shaped boxes, suitable for hexagonal prism-shaped boxes with a hexagonal cross-section. The irregularly shaped box is an open box at one end and closed at the other, with a defoaming strip attached to the inner wall of the box opening. This defoaming machine squeezes the defoaming strip, pressing it firmly against the irregularly shaped box and removing air bubbles between the strip and the box, ensuring a secure adhesion. The defoaming machine includes a platform 1 and a mold frame 2 mounted on the platform 1, as well as a box-removing robot, a box-pushing device, and a defoaming device 3 adapted to the irregularly shaped box, all mounted on the platform 1.

[0041] Please refer to Figure 2-7 Specifically, the defoaming device 3 includes an inner mold and an outer mold 34. The inner mold and the outer mold 34 cooperate to press the mouth strip and the irregularly shaped box together to remove bubbles. The inner mold includes a base 31, a bottom edge bubble-pressing assembly 32, and a pair of side bubble-pressing fixed molds 33. The base 31 of the inner mold is fixed on the mold frame 2. The base 31 includes a Teflon body 311 and a metal connecting plate 312. The metal connecting plate 312 is fixed on the Teflon body 311. The two side bubble-pressing fixed molds 33 are fixed on the metal connecting plate 312 and are symmetrically distributed on both sides of the bottom edge bubble-pressing assembly 32. The side bubble-pressing fixed molds 33 have a first bubble-pressing surface 331 and a second bubble-pressing surface 332 that respectively fit with the mouth strip of the irregularly shaped box. In this embodiment, the side bubble-pressing fixed molds 33 are triangular. The side bubble pressing mold 33 is also provided with a guide slope and a positioning flange 333. When the irregular box is fitted onto the side bubble pressing mold 33, the guide slope guides the irregular box to be smoothly fitted onto the side bubble pressing mold 33, while the positioning flange 333 stops the irregular box from continuing to move forward, thus playing a positioning role.

[0042] Please refer to Figure 1-7The outer mold 34 is paired with the side bubble pressing mold 33. The number of outer molds 34 is the same as the number of side bubble pressing molds 33, that is, there are also two outer molds 34. The outer molds 34 correspond one-to-one with the side bubble pressing molds 33. The outer mold 34 has a third bubble pressing surface 341 and a fourth bubble pressing surface 342. The third bubble pressing surface 341 matches the first bubble pressing surface 331, and the fourth bubble pressing surface 342 matches the second bubble pressing surface 332. In addition, the platform 1 is also equipped with an outer mold 34 driving assembly. The outer mold 34 driving assembly can be a linear drive mechanism such as a cylinder, hydraulic cylinder, or electric push rod. In this embodiment, the outer mold 34 driving assembly uses an outer mold 34 cylinder. The outer mold 34 is connected to the outer mold 34 cylinder. When the irregular box is fitted onto the side bubble-pressing fixed mold 33 of the inner mold, the outer mold 34 cylinder extends, driving the outer mold 34 to move closer to the side bubble-pressing fixed mold 33. The outer mold 34 and the side bubble-pressing fixed mold 33 are used to squeeze the strips on both sides of the irregular box to achieve bubble removal. It should be noted that the third bubble-pressing surface 341 and the fourth bubble-pressing surface 342 of the outer mold 34 are both covered with a buffer layer 54. The buffer layer 54 can be made of a certain hardness and has a certain rubber pad or other materials to prevent the outer mold 34 from leaving indentations on the surface of the irregular box during the extrusion and bubble removal process.

[0043] In this embodiment, the bottom edge bubble-pressing assembly 32 includes a bottom edge drive component, a connecting block 322, and a liftable bottom edge bubble-pressing block 323. The bottom edge drive component is fixed on the mold frame 2. The bottom edge drive assembly can be a linear drive mechanism such as a cylinder, hydraulic cylinder, or electric push rod. In this embodiment, the bottom edge drive assembly uses a bottom edge cylinder 321. The connecting block 322 is connected to the bottom edge cylinder 321 and the bottom edge bubble-pressing block 323. The bottom edge cylinder 321 drives the bottom edge bubble-pressing block 323 to rise and fall through the connecting block 322. In the initial state, the bottom edge cylinder 321 is in a retracted state. After the irregular box is fitted into the side bubble-pressing mold 33, the bottom edge cylinder 321 extends, causing the bottom edge bubble-pressing block 323 to move downward and press down on the lip strip to remove bubbles.

[0044] In this embodiment, the base 31 is provided with a clearance groove 313 to avoid the connecting block 322, so as to facilitate the up and down movement of the connecting block 322.

[0045] In this embodiment, the box-pushing device includes a box-pushing cylinder 51, a box-pushing plate 52, and a box-pushing channel. The box-pushing channel is composed of a pair of limiting plates 53 fixed to the platform 1. The irregularly shaped box can only move through the channel between the two limiting plates 53. The box-pushing cylinder 51 is fixed on the platform 1, and the box-pushing plate 52 is connected to the box-pushing cylinder 51. The box-pushing plate 52 is provided with a negative pressure suction cup for adsorbing the packaging box. The negative pressure suction cup is connected to the external negative pressure. When the irregularly shaped box is placed in the box-pushing channel, the box-pushing plate 52 pushes the box forward and sucks up the irregularly shaped box, and pushes the irregularly shaped box to move along the box-pushing channel until the irregularly shaped box is fitted onto the side bubble-pressing mold 33 of the inner mold. After the bubble is removed, the box-pushing cylinder 51 retracts, and the box-pushing plate 52 removes the irregularly shaped box from the inner mold, waiting for the box-picking robot to grab and transfer it.

[0046] In this embodiment, the box-retrieving robot includes a lateral movement mechanism 41 and a box-retrieving unit. The lateral movement mechanism 41 is fixed on the frame and uses a lead screw driven by a servo motor. The box-retrieving unit is connected to the lead screw, which enables the box-retrieving unit to move left and right. The box-retrieving unit in this embodiment includes a lifting mechanism 421 and a vacuum nozzle 422. The lifting mechanism 421 includes a lifting cylinder 4211 and a nozzle connector 4212 installed on the lifting cylinder 4211. The lifting cylinder 4211 is connected to the lateral movement mechanism 41. The vacuum nozzle 422 is installed on the nozzle connector 4212. The lifting mechanism 421 also has a pre-positioning plate 423. In this embodiment, the pre-positioning plate 423 is V-shaped and adapted to a hexagonal prism-shaped box. When the irregularly shaped box to be debubbled is picked up from the box-feeding conveyor belt, the lateral movement mechanism 41 drives the lifting cylinder 4211 to move to the left. The lifting cylinder 4211 then extends downward. The prepositioning plate 423 ensures that the vacuum nozzle 422 faces and can suck up the top surface of the irregularly shaped box. After the irregularly shaped box is sucked up by the vacuum nozzle 422, the lifting cylinder 4211 retracts upward. The lateral movement mechanism 41 drives the lifting cylinder 4211 to move to the right. Then the lifting cylinder 4211 extends downward to place the irregularly shaped box to be debubbled on the box-placement plate. Then the negative pressure of the vacuum nozzle 422 is disconnected to release the irregularly shaped box. The lifting cylinder 4211 retracts upward to reset, waiting for the next leftward movement to pick up the box.

[0047] This utility model employs a side bubble-pressing mold 33 similar to that used in irregularly shaped boxes, and a liftable bottom bubble-pressing component 32. The side bubble-pressing mold 33 and the outer mold 34 work together to squeeze and remove bubbles from the side opening of the irregularly shaped box, and the bottom bubble-pressing component 32 squeezes and removes bubbles from the bottom opening of the irregularly shaped box, thus achieving bubble removal from the opening of a packaging box with a hexagonal cross-section.

[0048] 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.
