When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Please see Figures 1 to 8 The packaging box fastening device according to one embodiment of the present invention includes a conveyor belt 10, a box positioning component 20 installed at one end of the conveyor belt 10, and an upper cover positioning component 30 installed above the box positioning component 20.

[0033] The conveyor belt 10 is used to transport the carrier plate 11. A box 12 is placed at one end of the carrier plate 11, and a top cover 13 is placed at the other end of the carrier plate 11.

[0034] The box positioning assembly 20 includes a bracket 21, a first pressing wheel 22 retractably mounted on the top of the bracket 21, a lifting frame 23 located on one side of the bracket 21, a second pressing wheel 24 retractably mounted on the top of the lifting frame 21, and clamping arms 25 slidably mounted on opposite sides of the top of the lifting frame 23.

[0035] The support 21 is located on one side of the conveyor belt 10, and the lifting frame 23 is located on the other side of the conveyor belt 10. The support 21 and the lifting frame 23 are arranged opposite each other, and the first pressing wheel 22 and the second pressing wheel 24 are arranged opposite each other. The first pressing wheel 22 is connected to the support 21 via a cylinder, and the second pressing wheel 24 is connected to the lifting frame 23 via a cylinder. Driven by the cylinders, the first pressing wheel 22 and the second pressing wheel 24 can move closer to each other, thereby pressing the two sides of the box body 12. The clamping arms 25 are connected to opposite sides of the lifting frame 23 via cylinders. Driven by the cylinders, the two clamping arms 25 can move closer to each other, thereby pressing the other two sides of the box body 12. At this point, the box body positioning assembly 20 positions the box body 12, making it easier for the top cover positioning assembly 30 to clamp the top cover 13 and fasten it onto the box body 12.

[0036] In this embodiment, the lifting frame 23 is an electric slide table; the lifting frame 23 is provided with a sliding slide, which is used to support and connect the two second clamping wheels 24 and the two clamping arms 25.

[0037] The upper cover positioning assembly 30 includes a transfer platform 31, a support plate 32 connected to one side of the transfer platform 31, first clamping blocks 33 slidably mounted on opposite sides of the bottom surface of the support plate 32, pushing elements 34 respectively connected to each of the first clamping blocks 33, second clamping blocks 35 slidably mounted on opposite ends of the bottom surface of the support plate 32, springs 36 connecting the second clamping blocks 35 and the support plate 32, a support plate 37 parallelly spaced below the support plate 32, and multiple suction cups 38 mounted on the support plate 37; the springs 36 are used to drive the two second clamping blocks 35 away from each other, so that the second clamping blocks 35 abut against the first clamping blocks 33, thereby causing the second clamping blocks 35 to move synchronously with the first clamping blocks 33.

[0038] In this embodiment, the pushing element 34 is a cylinder; the pushing element 34 is installed on the top surface of the support plate 32, and the piston rod of the pushing element 34 is connected to the adapter block 340. The adapter block 340 passes through the support plate 32 and is connected to the first clamping block 33 to drive the first clamping block 33 to move.

[0039] In this embodiment, the support plate 32 is generally arranged in a cross shape, and the center line connecting the two first clamping blocks 33 is perpendicular to the center line connecting the two second clamping blocks 35; the area enclosed between the two first clamping blocks 33 and the two second clamping blocks 35 is used to accommodate the upper cover 13. The two first clamping blocks 33 are used to abut against two sides of the upper cover 13, and the two second clamping blocks 35 are used to abut against the other two sides of the upper cover 13 to achieve positioning of the upper cover 13.

[0040] Specifically, such as Figures 6 to 8 As shown, a pulley 330 is rotatably mounted on one end of the first clamping block 33 near the center of the support plate 32; a guide plate 350 is connected to one end of the second clamping block 35 near the center of the support plate 32, and the angle between the length direction of the guide plate 350 and the length direction of the second clamping block 35 is an acute angle, and the guide plate 350 is used to abut against the pulley 330; the first clamping block 33 synchronously drives the second clamping block 35 to move.

[0041] In practical use, the pushing element 34 drives the two first clamping blocks 33 to move away from each other, and the pulleys 330 on the two first clamping blocks 33 also move away from each other, increasing the distance between the two pulleys 330. Under the action of the spring 36, the guide plate 350 moves outward synchronously to keep abutting against the pulley 330, so that the two second clamping blocks 35 move away from each other synchronously, making it convenient for the first clamping blocks 33 and the second clamping blocks 35 to surround the upper cover 13. Then, the pushing element 34 drives the two first clamping blocks 33 to move closer to each other, and the pulleys 330 on the two first clamping blocks 33 also move closer to each other, decreasing the distance between the two pulleys 330. The pulleys 330 press the guide plate 350, causing the two second clamping blocks 35 to move closer to each other synchronously until the two first clamping blocks 33 abut against two sides of the upper cover 13, and the two second clamping blocks 35 abut against the other two sides of the upper cover 13, so as to achieve positioning and clamping of the upper cover 13. The suction cup 38 picks up the upper cover 13 for further fixation, at which time the spring 36 is in a compressed state. After the top cover 13 is positioned and clamped, the transfer platform 31 starts and moves the top cover 13 to a position directly above the box body 12 before it falls to fasten the top cover 13 to the box body 12. Compared with traditional manual or semi-automatic fastening, the packaging box fastening device of the present invention has a high degree of automation. The first clamping block 33 can drive the second clamping block 35 to move synchronously, which facilitates the clamping of the top cover 13. The transfer platform 31 then moves the top cover 13 to the top of the box body 12 for fastening, which can automatically achieve the fastening of the top cover and the box body, effectively improving packaging efficiency and packaging quality.

[0042] In this embodiment, the transfer platform 31 includes a first linear module 311 and a second linear module 312 vertically connected to the first linear module 311; the second linear module 312 is used to support the connecting support plate 32. The movement direction of the first linear module 311 is consistent with the transmission direction of the conveyor belt 10. Both the first linear module 311 and the second linear module 312 are electric slides.

[0043] The above-mentioned packaging box fastening device has a simple structure, is easy to use, and has a high degree of automation. It uses the first clamping block 33 to drive the second clamping block 35 to move synchronously, which facilitates the clamping of the top cover 13 and the transfer platform 31 to transfer the top cover 13 to the top of the box body 12 for fastening. It can automatically realize the fastening of the top cover and the box body, effectively improving packaging efficiency and packaging quality.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
