Description

Technical Field

[0001] This utility model relates to the field of paper box sealing technology, and in particular to a paper box sealing folding device. Background Technology

[0002] A cardboard box is a three-dimensional shape, composed of multiple facets that are moved, stacked, folded, and enclosed. In three-dimensional composition, facets divide space; cutting, rotating, and folding different facets creates different emotional expressions. When designing the display surfaces of a cardboard box, attention should be paid to the connections between the display surface, sides, top, and bottom, as well as the placement of packaging information elements.

[0003] Existing cardboard box sealing and folding devices require adjustments to the folding stroke and the stroke of the mechanism used to fix the cardboard box when folding cardboard boxes of different sizes. Otherwise, if the cardboard box moves beyond its position, it will be pressed and deformed. Furthermore, the adjustment process requires repeated calibration, which is quite troublesome. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a paper box sealing and folding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A paper box sealing and folding device includes a folding table, a mounting frame is provided on the top of the folding table, and a hydraulic cylinder is provided on the top of the mounting frame. The output end of the hydraulic cylinder is connected to a connecting table through a hydraulic rod.

[0007] The bottom of the connecting platform is provided with a mounting shaft, and a folding mechanism is rotatably mounted on the bottom of the mounting shaft. The folding mechanism is connected to the mounting shaft by a main rod, and the bottom end of the main rod is provided with an elastic hinge. The end of the main rod is connected to a pressing rod through the elastic hinge, and an electric telescopic rod is provided on the inner side of the mounting frame.

[0008] Furthermore, in a preferred configuration, the folding platform is provided with a conveyor roller inside, and the folding mechanism inside the mounting frame does not contact the conveyor roller.

[0009] In addition, a preferred structure is that the top of the mounting bracket is provided with guide rods on both sides of the hydraulic cylinder, and the guide rods pass through the mounting bracket and connect to the connecting platform.

[0010] Furthermore, in a preferred configuration, the end of the electric telescopic rod inside the mounting frame is connected to the folding mechanism, and the folding mechanism is in a vertical position when it is not in contact with the cardboard box.

[0011] Furthermore, in a preferred configuration, when the pressing rod at the end of the folding mechanism contacts the cardboard box, the pressing rod and the main guide rod on the folding mechanism are in opposite states.

[0012] Furthermore, in a preferred configuration, when the connecting platform is raised or lowered by a hydraulic rod, the end of the electric telescopic rod is always positioned at the part of the main guide rod on the folding mechanism.

[0013] The beneficial effects of this utility model are as follows: Firstly, the folding mechanism set at the bottom of the mounting frame at the top of the folding table can seal and fold the paper box, and the conveying roller can ensure that it will not be skewed. Furthermore, the hydraulic rod at the top and the electric telescopic rod on the side can adjust the position of the folding mechanism when folding paper boxes of different sizes, making it convenient to fold paper boxes of different sizes.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A paper box sealing and folding device includes a folding table 1, a mounting frame 2 is provided on the top of the folding table 1, and a hydraulic cylinder 4 is provided on the top of the mounting frame 2, and the output end of the hydraulic cylinder 4 is connected to a connecting table 6 through a hydraulic rod 41.

[0021] The bottom of the connecting platform 6 is provided with a mounting shaft 61, and a folding mechanism 7 is rotatably mounted on the bottom of the mounting shaft 61. The folding mechanism 7 is connected to the mounting shaft 61 as a main rod, and the bottom end of the main rod is provided with an elastic hinge 71. The end of the main rod is connected to a pressing rod 72 through the elastic hinge 71. An electric telescopic rod 8 is provided on the inner side of the mounting frame 2.

[0022] The folding platform 1 is equipped with a conveyor roller 3 inside, and the folding mechanism 7 inside the mounting frame 2 does not contact the conveyor roller 3. The working principle and circuit connection of the conveyor roller 3 are existing technologies and will not be described in detail.

[0023] Meanwhile, guide rods 5 are provided on both sides of the top of the mounting frame 2, and the guide rods 5 pass through the mounting frame 2 and are connected to the connecting platform 6.

[0024] Furthermore, the end of the electric telescopic rod 8 inside the mounting bracket 2 is connected to the folding mechanism 7, and the folding mechanism 7 is in a vertical state when it is not in contact with the cardboard box.

[0025] Furthermore, when the pressing rod 72 at the end of the folding mechanism 7 comes into contact with the cardboard box, the pressing rod 72 and the main guide rod on the folding mechanism 7 are in opposite states.

[0026] Furthermore, when the connecting platform 6 is raised or lowered by the hydraulic rod 41, the end of the electric telescopic rod 8 is always located at the part of the main guide rod on the folding mechanism 7.

[0027] In this embodiment, the cardboard box that needs to be sealed and folded is first placed on one side of the folding table 1. Then, the hydraulic cylinder 4 at the top of the mounting frame 2 is controlled by the operator's visual operation, and then the bottom hydraulic rod 41 is driven to control the height of the connecting platform 6 inside the mounting frame 2.

[0028] Then, the cardboard box that needs to be folded can be placed on the conveyor roller 3. The cardboard box will then slowly move towards the folding mechanism 7 at the bottom of the mounting frame 2 via the conveyor roller 3. Since the speed of the conveyor roller 3 is constant and slow, the folding mechanism 7 can be moved by the electric telescopic rod 8 inside the mounting frame 2. Since the top of the folding mechanism 7 is mounted on the mounting shaft 61, the pressing rod 72 at the bottom of the main guide rod in the upper part of the folding mechanism 7 will rotate in the opposite direction via the elastic hinge 71. The main guide rod and the pressing rod 72 in the upper part are in different rotation states. At this time, the cardboard box can be sealed and folded by the pressing rod 72.

[0029] In this utility model, the folding mechanism 7 set at the bottom of the mounting frame 2 at the top of the folding table 1 can seal and fold the paper box. The conveying roller 3 can ensure that it will not be skewed. The hydraulic rod 41 at the top and the electric telescopic rod 8 on the side can adjust the position of the folding mechanism 7 when folding paper boxes of different sizes, so as to facilitate the folding of paper boxes of different sizes.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
