Description

Technical Field

[0001] This utility model belongs to the field of paper box forming technology, and in particular relates to a paper box frame demolding device. Background Technology

[0002] Packaging boxes are generally made by folding cardboard into shape and then attaching a face paper to the outer surface of the formed frame. Currently, some packaging boxes use strips of cardboard with multiple creases to form a frame structure, with an adhesive face paper attached to the outer surface of the frame. The edges of the face paper are folded back to secure the frame, and a bottom paper is then attached to the bottom of the frame, thus forming the box frame. For example, Chinese patent document CN114311844B discloses a method for assembling a box with a frame. An unfolded strip ultimately forms a shaped frame with its ends joined together, defined as the first frame. An unfolded strip can be divided into five segments: a first segment, a second segment, a third segment, a fourth segment, and a fifth segment. After the strip surrounds and forms the inner mold, the strip constitutes the frame, defined as the first frame. The second section of the webbing is tightly attached to the first surface of the inner mold, forming the first surface of the frame; the third section of the webbing is tightly attached to the second surface of the inner mold, forming the second surface of the frame; the fourth section of the webbing is tightly attached to the third surface of the inner mold, forming the third surface of the frame; the first and fifth sections of the webbing are tightly attached to the fourth surface of the inner mold, and together they form the fourth surface of the frame. In other words, after an unfolded webbing forms a shaped frame with its ends joined together, it becomes the first frame. The first frame has four surfaces: the first surface, the second surface, the third surface, and the fourth surface, where the first and fifth sections of the webbing together form the fourth surface. A boxing device is also provided to realize the webbing frame. After the frame is completed, it needs to be removed from the frame mold.

[0003] Chinese invention patent document CN114434696B discloses an automatic demolding process and a frame forming process, including the following steps: S1, pushing the frame out from one side of the inner mold body until the frame is at least partially detached from the inner mold body; S2, catching the pushed-out frame on the side where it was pushed out; S3, while catching the frame, the frame continues to be pushed and / or pulled until it is completely detached from the inner mold body. Further, in step S3, the frame changes its posture during the stroke of detaching from the inner mold body. In step S2, the pushed-out frame is caught by a frame-receiving component located on the side where it was pushed out. The change in frame posture during the stroke of detaching from the inner mold body is achieved by: setting a flipping component to flip the frame-receiving component to change the frame posture; the flipping component completes the directional rotation of the frame component by moving away from the inner mold body, thereby completing the change in frame posture on the frame-receiving component. Furthermore, the frame assembly includes a gripper located on the other side of the inner mold body. When the frame is pushed horizontally from the inner mold body to the other side, the pushed-out frame side plate enters the clamping cavity formed by the gripper in the open state, and the gripper clamps and holds the frame. The frame forming process involves a frame assembly comprising a face paper and a grey board. The face paper is first glued and consists of four sides from left to right: a first side, a second side, a third side, and a fourth side. The grey board consists of four segments from left to right: a first segment, a second segment, a third segment, and a fourth segment. The first, second, and third segments of the grey board are bonded to the second, third, and fourth sides of the face paper, respectively. The process includes the following steps: ① The frame assembly is placed below the inner mold body, with the second segment of the grey board located directly below the inner mold body; ② The inner mold body is pressed down, folding the first, third, and fourth segments of the grey board into a vertical position perpendicular to the second segment and fixing them in place; ③ The fourth segment of the grey board is folded so that it fits against the top of the inner mold body; ④ The first side of the face paper is folded so that it is bonded to the folded fourth segment; ⑤ The frame demolding process described above.

[0004] In the technical solution of the above patent literature, after the frame is formed, the face paper protrudes from the fourth section. After demolding, this part of the face paper needs to be reversed and pasted to the inside of the frame, which adds a pasting process. Utility Model Content

[0023] In one embodiment of the paper box frame demolding device of this utility model, please refer to... Figures 1 to 5A carton frame demolding device is used to remove the carton frame from the frame mold 10 after it has been formed on the frame mold 10. Specifically, the carton frame demolding device includes a support base 100, a linear mechanism 200, a receiving mechanism, a flipping base 400, a flipping drive component 500, and a lifting mechanism 600. The linear mechanism 200 is located on the top side of the support base 100. The moving end of the linear mechanism 200 is provided with two side plates 210. The lower end of the side plates 210 extends inward with an abutment plate 220 for abutting against the end side of the frame on the frame mold 10. The receiving mechanism is located on one side of the support base 100. The receiving mechanism is provided with a receiving mold 300, which has a mold cavity 301 for receiving the frame pushed out by the frame mold 100. A translation mechanism 700 is provided above the receiving mold 300. The moving end of the translation mechanism 700 is provided with a hook plate 710, and the bottom end of the hook plate 710 extends a hook portion 711, which forms a pressing gap with the top side of the mold cavity 301. A flipping seat 400 is rotatably connected within the support base 100 and located at the bottom end of the receiving mold 300. The flipping seat 400 is provided with a receiving groove 401 for receiving the frame that has exited the receiving mold 300. A flipping drive 500 is connected to the flipping seat 400 to drive the flipping seat 400 to flip. A lifting mechanism 600 is connected to the receiving mold 300 or the flipping seat 400 to drive the receiving mold 300 or the flipping seat 400 to move up and down. Preferably, the lifting mechanism 600 drives the flipping seat 400 to move up and down. Specifically, the carton frame demolding device also includes a lifting seat 800, which is connected to a lifting mechanism, and the flipping seat 400 is rotatably connected to the lifting seat 800. Guide rails are provided between the lifting seat 800 and the two sides of the support seat 100, so that the lifting seat 800 can move up and down.

[0024] In the above embodiment, when the carton frame demolding device completes the demolding of the frame, the linear module 200 moves, causing the two abutment plates 220 to be positioned on the frame end side formed on the frame mold 10. The linear module 200 drives the abutment plates 220 to move, thereby removing the frame from the frame mold 10 and pushing it into the mold cavity 301 of the receiving mold 300. The translation mechanism 700 drives the hook portion 711 of the hook plate 710 to extend into the frame of the mold cavity 301, and pushes it down through the hook portion 711, folding and attaching the face paper of the protruding part on the top side of the frame to the inside of the frame. Therefore, the folding and attachment of the face paper is completed during the demolding of the frame. While folding, the lifting mechanism 600 drives the flipping seat 400 to rise, so that the frame can be transferred to the receiving groove 401. Then, the flipping drive 500 drives the flipping seat 400 to flip, so that the frame can be flipped to a flat state, so that the frame can be taken out from the receiving groove 401 and transported to the next process.

[0025] Furthermore, refer to Figure 1 box Figure 2The bottom end of the side plate 210 is also provided with a horizontal push cylinder 230, and an abutment plate 220 is provided on the horizontal push cylinder 230. The abutment plate 220 is L-shaped, and a suction cup 240 is provided on one inner side of the abutment plate 220 for adhering to the outer side of the frame. The receiving mold 300 has clearance notches 302 on both sides for clearing the horizontal push cylinder 230. In this embodiment, when the frame is removed from the frame mold 10, the horizontal push cylinder 230 pushes the abutment plate 220 to move, so that one side of the abutment plate 220 is limited to the end side of the frame, while the suction cup 240 is adhering to the outer side of the frame, thereby making it easier to push the frame out of the frame mold 10.

[0026] Furthermore, refer to Figures 2 to 4 The receiving mechanism also includes an ejection mechanism 320, located on the back side of the receiving mold 300, for ejecting the frame inside the receiving mold 300. Specifically, the ejection mechanism 320 includes an ejection cylinder 321 and an ejection pusher 322. The receiving mold 300 is located in a guide groove 303, and the ejection pusher 322 is slidably disposed in the guide groove 303. The ejection cylinder 321 is connected to the ejection pusher 322. Specifically, in this embodiment, when the frame is transferred from the mold cavity 301 to the receiving groove 401, the ejection cylinder 321 drives the ejection pusher 322, thereby ejecting the frame from the mold cavity 301. The frame is hooked onto the top side wall of the frame by the hook 711, and the frame is located on the top side of the receiving groove 401. The frame is then rotated into the receiving groove 401 by the upward movement of the flipping seat 400.

[0027] Furthermore, referring to Figure 4 and Figure 5 The receiving mechanism also includes a lifting seat 330 and a lifting cylinder 340. The lifting seat 330 is slidably connected within the support seat 100 and located above the receiving mold 300. The lifting cylinder 340 is disposed on the receiving mold 300 and connected to the lifting seat 330, used to drive the lifting seat 330 to move up and down. A translation mechanism 700 is disposed on the lifting seat 330. Specifically, in this embodiment, when the hook 711 folds the protruding part of the top face paper into the inner wall of the frame, the lifting cylinder 340 drives the lifting seat 330 to move downward, causing the hook 711 to descend together, bending the protruding face paper downward by 90°, and then the hook 711 folds the bent part of the face paper in the opposite direction into the inner wall of the frame.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
