Description

Technical Field

[0001] This utility model relates to the field of box-making machine technology, and in particular to a window edge-wrapping device for a packaging box and a packaging box with windowed facing paper forming machine. Background Technology

[0002] With the increasing popularity of modern high-end gift boxes / packaging boxes, the variety of gift boxes / packaging boxes is also constantly increasing. In order to meet the packaging needs of various products, the appearance of gift boxes / packaging boxes has also increased many requirements. Window packaging boxes are one type of gift box / packaging box.

[0003] Window packaging boxes, due to their window design, allow for the display of packaged items. Window packaging boxes have wide applications and high demand, requiring high production efficiency. Existing patents include a Chinese patent application (application number 201620772484.6) that discloses an automatic edge-sealing machine for packaging box display windows. This machine includes a work platform, an edge-sealing mechanism, a pressing module, and a start switch and control switch on the work platform. The work platform has four lockable pulleys at its bottom, a positioning plate in the center, and three positioning blocks on its outer edge, located at three different positions on the positioning plate. The edge-sealing mechanism consists of an edge-sealer and driving cylinders. The driving cylinders are a front cylinder, a rear cylinder, a left cylinder, and a right cylinder fixed to the work platform and located at the front, rear, left, and right positions of the positioning plate. The edge-sealer consists of a front chamfering piece, a rear chamfering piece, and a... The device consists of a left chamfer piece and a right chamfer piece. The four sets of chamfer pieces are all horizontally arranged and are completely exposed above the positioning plate, forming the shape of a display window for the packaging box. The bottom of each of the four sets of chamfer pieces is vertically fixed to a downwardly connected connector. The shafts of the four sets of cylinders pass through the bottom of the positioning plate and are fixedly connected to the connectors on the four sets of chamfer pieces. The pressing module is fixed above the edge banding device by a support frame on the working platform. The pressing module consists of a pressing cylinder and a pressing mold fixed to the shaft of the pressing cylinder. The shaft of the pressing cylinder is vertically arranged, and the bottom of the pressing mold is grooved. During operation, driven by the pressing cylinder, the pressing mold can completely accommodate the edge banding device and contact the positioning plate. Although the patent document can automatically edge the window of the window packaging box, it requires the front cylinder, rear cylinder, left cylinder and right cylinder to drive the front chamfering piece, rear chamfering piece, left chamfering piece and right chamfering piece to work independently. It requires multiple drive sources, which is costly and the structure is not compact enough. It is also difficult to control the working synchronization of the front chamfering piece, rear chamfering piece, left chamfering piece and right chamfering piece.

[0004] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a window edge-sealing device for packaging boxes and a packaging box with windowed facing paper forming machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A window edge-sealing device for a packaging box includes a lower mold fixing base, a lower mold support frame elastically and vertically disposed on the top surface of the lower mold fixing base, an edge-sealing driver embedded in the center of the top surface of the lower mold fixing base, four edge-sealing plates respectively disposed on the four output ends of the edge-sealing driver, an upper mold pressing frame vertically disposed above the lower mold support frame and corresponding to the lower mold support frame, and a lifting drive mechanism fixedly connected to the upper mold pressing frame and used to drive the upper mold pressing frame to rise and fall. The four edge-sealing plates are distributed in the front, back, left, and right directions of the edge-sealing driver. The edge-sealing driver is used to drive the four edge-sealing plates to converge or expand with each other. When the four edge-sealing plates converge, the four edge-sealing plates are located inside the lower mold support frame, and there is an elastic space between the bottom surface of the lower mold support frame and the top surface of the lower mold fixing base.

[0008] Furthermore, the edge-binding actuator is a four-claw finger cylinder.

[0009] Furthermore, the window edging device of the packaging box also includes a bracket installed on the lifting end of the lifting drive mechanism, and the upper molding frame is installed at the bottom end of the bracket.

[0010] Furthermore, the bracket is equipped with a lifting driver inside, and the lifting end of the lifting driver is equipped with a pressure block. The pressure block is lifted and positioned inside the upper mold pressure frame, and the pressure block is correspondingly positioned with the lower mold support frame.

[0011] Furthermore, the window sealing device of the packaging box also includes a box ejector pin and a box ejector driver for driving the box ejector pin to rise and fall, with the box ejector pin sliding vertically through the bracket and the pressure block.

[0012] Furthermore, the lower mold support frame is elastically connected to the lower mold fixing seat via an elastic element, which is located within the elastic space.

[0013] Furthermore, the top surface of the lower mold fixing seat is recessed in the middle of the insert cavity, and the edge-binding driver is located in the insert cavity.

[0014] Furthermore, the window sealing device for the packaging box also includes four bubble pressing mechanisms distributed around the lower mold fixing base.

[0015] Furthermore, the bubble pressing mechanism includes a bubble pressing driver and a bubble pressing plate mounted on the driving end of the bubble pressing driver. The bubble pressing plate is located outside the lower mold fixing seat, and the bubble pressing driver is used to drive the bubble pressing plate closer to or further away from the lower mold fixing seat.

[0016] This utility model also provides a packaging box with windowed facing paper forming machine, including a box feeding mechanism, a box holding mechanism, an output mechanism, and a window edge-sealing device for the aforementioned packaging box. The window edge-sealing device is located on the output side of the box feeding mechanism, and the output mechanism is located on the side of the window edge-sealing device away from the box feeding mechanism. The box holding mechanism is movably arranged above the box feeding mechanism, the window edge-sealing device, and the output mechanism.

[0017] The beneficial effects of this utility model are as follows: In practical applications, the window packaging box with the outer surface pasted with face paper is placed on the lower mold support frame, so that the four edge panels in a gathered state are located inside the window of the window packaging box, and the window packaging box is located directly below the upper mold pressing frame. Then, the lifting drive mechanism drives the upper mold pressing frame to descend. The descending upper mold pressing frame extends into the window packaging box and partially presses the inner side of the window packaging box against the lower mold support frame, causing the lower mold support frame to descend, thereby reducing the elastic space. As the lower mold support frame and the window packaging box descend, the four edge panels... The edge plates bend upwards against the window side of the face paper. Then, the edge-sealing driver drives the four edge-sealing plates to expand relative to each other, so that the four edge-sealing plates respectively stick the window side of the face paper to the inner side of the window packaging box, thereby achieving window edge sealing of the window packaging box. Finally, the edge-sealing driver drives the four edge-sealing plates to converge, and the lifting drive mechanism drives the upper molding frame to rise. After the lifting drive mechanism drives the upper molding frame to rise and reset, the upper molding frame separates from the window packaging box, and the lower mold support frame rises and resets under the action of spring force, so as to facilitate the production of the next window packaging box. This utility model uses an edge-sealing driver (drive source) to drive four edge-sealing plates to converge or expand relative to each other. The four edge-sealing plates have good working synchronization, reducing the number of drive sources, resulting in a compact structure and reduced production costs. Furthermore, by pressing the window packaging box first and then performing edge sealing, the stability and quality of the edge sealing are good. Attached Figure Description

[0028] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0029] like Figures 1 to 8 As shown, the present invention provides a window edge-sealing device for a packaging box, which includes a lower mold fixing base 1, a lower mold support frame 2 elastically and vertically disposed on the top surface of the lower mold fixing base 1, an edge-sealing driver 3 embedded in the middle of the top surface of the lower mold fixing base 1, four edge-sealing plates 4 respectively installed on the four output ends of the edge-sealing driver 3, an upper mold pressing frame 5 vertically disposed above the lower mold support frame 2 and correspondingly disposed on the lower mold support frame 2, and a lifting drive mechanism 6 fixedly connected to the upper mold pressing frame 5 and used to drive the upper mold pressing frame 5 to rise and fall. The four edge-sealing plates 4 are distributed in the front, back, left and right directions of the edge-sealing driver 3. The edge-sealing driver 3 is used to drive the four edge-sealing plates 4 to converge or expand with each other. When the four edge-sealing plates 4 converge, the four edge-sealing plates 4 are located inside the lower mold support frame 2, and there is an elastic space 7 between the bottom surface of the lower mold support frame 2 and the top surface of the lower mold fixing base 1.

[0030] In practical applications, the window packaging box with the outer surface covered with face paper is placed on the lower mold support frame 2, so that the four edge-sealing plates 4, which are in a gathered state, are located inside the window of the window packaging box, and the window packaging box is located directly below the upper mold pressing frame 5. Then, the lifting drive mechanism 6 drives the upper mold pressing frame 5 to descend. The descending upper mold pressing frame 5 extends into the window packaging box and partially presses the inner side of the window packaging box against the lower mold support frame 2, causing the lower mold support frame 2 to descend, so that the elastic space 7 decreases. As the lower mold support frame 2 and the window packaging box descend, the four edge-sealing plates 4 will abut against the surface. The window side of the paper is bent upwards, and then the edge-sealing driver 3 drives the four edge-sealing plates 4 to expand relative to each other, so that the four edge-sealing plates 4 respectively stick the window side of the face paper to the inner side of the window packaging box to achieve the window edge sealing of the window packaging box. Finally, the edge-sealing driver 3 drives the four edge-sealing plates 4 to converge relative to each other, and the lifting drive mechanism 6 drives the upper molding frame 5 to rise. After the lifting drive mechanism 6 drives the upper molding frame 5 to rise and reset, the upper molding frame 5 separates from the window packaging box, and the lower mold support frame 2 rises and resets under the action of the rebound force to facilitate the production of the next window packaging box. This utility model uses an edge-sealing driver 3 (drive source) to drive the four edge-sealing plates 4 to converge or expand relative to each other. The four edge-sealing plates 4 have good working synchronization, reducing the number of drive sources, resulting in a compact structure, reduced production costs, and good stability and quality of edge sealing due to the window packaging box being pressed first before edge sealing.

[0031] In this embodiment, the edge-binding actuator 3 is a four-claw finger cylinder. This structural design is simple, provides good synchronization of driving the four edge-binding plates 4, and is low in cost.

[0032] In this embodiment, the window edging device of the packaging box also includes a bracket 8 installed on the lifting end of the lifting drive mechanism 6, and the upper molding frame 5 is installed on the bottom end of the bracket 8. This structural design facilitates the assembly of the lifting drive mechanism 6 and the upper molding frame 5.

[0033] In this embodiment, a lifting driver 9 is installed inside the bracket 8. A pressure block 10 is installed at the lifting end of the lifting driver 9. The pressure block 10 is lifted and positioned inside the upper mold pressing frame 5, and the pressure block 10 is correspondingly arranged with the lower mold support frame 2. Specifically, the lifting driver 9 can be a cylinder. After the four edge-sealing plates 4 are pasted to the inner side of the window packaging box, and the edge-sealing driver 3 drives the four edge-sealing plates 4 to come together, the lifting driver 9 drives the pressure block 10 to descend, so that the pressure block 10 presses and pastes the window side of the face paper tightly to the inner side of the window packaging box, which not only makes the edge sealing firm, but also plays a role in suppressing bubbles.

[0034] In this embodiment, the window sealing device for the packaging box further includes a box ejector pin 11 and a box ejector driver for driving the box ejector pin 11 to rise and fall. The box ejector pin 11 slides vertically through the bracket 8 and the pressure block 10; specifically, the box ejector driver can be a cylinder. During the process of the lifting drive mechanism 6 driving the upper molding frame 5 to rise and reset, the box ejector driver drives the box ejector pin 11 to fall, so that the box ejector pin 11 abuts against the window packaging box, thereby realizing the demolding of the upper molding frame 5 from the window packaging box.

[0035] In this embodiment, the lower mold support frame 2 is elastically connected to the lower mold fixing seat 1 via an elastic element 12, and the elastic element 12 is located within the elastic space 7; specifically, the elastic element 12 can be a spring. During the process of the upper mold pressing frame 5 pressing down on the lower mold support frame 2, the lower mold support frame 2 moves down and compresses the elastic element 12, causing the elastic space 7 to shrink; when the upper mold pressing frame 5 releases the downward pressure on the lower mold support frame 2, the rebound force of the elastic element 12 causes the lower mold support frame 2 to rise and reset, and the elastic space 7 returns to its original state.

[0036] In this embodiment, the top surface of the lower mold fixing base 1 is recessed with an insert cavity 13, and the edge wrapping driver 3 is located in the insert cavity 13. This structural design not only facilitates the assembly of the edge wrapping driver 3, but also makes the structure of the edge wrapping driver 3 and the lower mold fixing base 1 compact.

[0037] In this embodiment, the window sealing device of the packaging box further includes four bubble pressing mechanisms 14 distributed around the lower mold fixing base 1. Preferably, the bubble pressing mechanism 14 includes a bubble pressing driver 15 and a bubble pressing plate 16 mounted on the driving end of the bubble pressing driver 15. The bubble pressing plate 16 is located outside the lower mold fixing base 1, and the bubble pressing driver 15 is used to drive the bubble pressing plate 16 closer to or further away from the lower mold fixing base 1. Specifically, the bubble pressing driver 15 can be a cylinder. In practical applications, the four bubble pressing mechanisms 14 perform bubble pressing treatment around the window packaging box, so that the face paper is tightly attached to the outside of the window packaging box.

[0038] Specifically, the lower mold fixing base 1 is driven by a lifting drive module, which is used to drive the lower mold fixing base 1 to rise and fall.

[0039] This utility model also provides a packaging box with windowed veneer forming machine, including a box feeding mechanism 17, a box holding mechanism 18, an output mechanism 19, and a window edge-sealing device for the aforementioned packaging box. The window edge-sealing device is located on the output side of the box feeding mechanism 17, and the output mechanism 19 is located on the side of the window edge-sealing device away from the box feeding mechanism 17. The box holding mechanism 18 is movably disposed above the box feeding mechanism 17, the window edge-sealing device, and the output mechanism 19.

[0040] In practical applications, the box feeding mechanism 17 transports the window packaging box to the box holding position, places the face paper above the window edge-sealing device of the packaging box, and the box holding mechanism 18 places the window packaging box on the face paper. Alternatively, the box feeding mechanism 17 transports the window packaging box with the face paper pasted on to the box holding position, and the box holding mechanism 18 places the window packaging box with the face paper pasted on the window edge-sealing device of the packaging box. Then, the window edge-sealing device attaches the face paper to the outer wall of the window packaging box and also attaches the window side of the face paper to the inner side of the window packaging box to achieve window edge sealing of the window packaging box. After the edge sealing is completed, the box holding mechanism 18 picks up the window packaging box and places it in the output mechanism 19, and the output mechanism 19 outputs the window packaging box.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
