Technical Field

[0001] The utility model belongs to the technical field of folding devices, and particularly relates to a folding device for packaging boards. Background Art

[0002] Packaging boards are usually made of materials such as corrugated paper, with a certain structural strength, and can thus well protect the items in the packaging box. The cartons used for tile packaging also adopt this kind of material.

[0003] In the production process of tile packaging boxes, the folding of packaging boards is a crucial link. However, traditional folding methods mainly rely on manual operation, which is not only inefficient but also labor-intensive. To address this challenge, some manufacturers introduce folding devices to assist manual folding of packaging boards. However, in actual applications, conventional folding devices can often only fold packaging boxes of a specific width, with poor versatility. This means that when different-sized packaging boxes need to be produced, different folding devices need to be replaced.

[0004] Therefore, it is necessary to design a new folding device for packaging boards to assist manual folding work of packaging boards. Summary of the Utility Model

[0022] In this embodiment, during use, first, the distance between the two limiting mechanisms is adjusted according to the width of the packaging board. After the adjustment is completed, the packaging board to be folded can be placed between the two limiting mechanisms so that the packaging board can be placed in the accurate position. Then, the double-shaft motor 5 is started. The double-shaft motor 5 drives the two screw rods 6 to rotate. The two screw rods 6 respectively drive the two connecting blocks 7 to slide in the two strip-shaped holes. The two connecting blocks 7 drive the two baffle plates 8 to approach or move away from each other, so that the distance between the two baffle plates 8 can conform to the width of the bottom of the packaging box. After the adjustment is completed, the double-shaft motor 5 can be turned off. Then, the pressing plate 15 on the pressing mechanism needs to be replaced. The selected pressing plate 15 needs to conform to the width of the bottom of the packaging box. After the replacement is completed, the pressing mechanism can be started to press the packaging board, and the packaging board is pressed into the groove body 3. Under the blocking action of the two baffle plates 8 and the multiple rollers, the crease part of the packaging board will react, so that the whole packaging board can be folded in a U shape, and the folding is relatively convenient. Thus, this device can be used to fold packaging boxes of different specifications, and has good versatility.

[0023] In a further preferred embodiment of the present utility model, the limiting mechanism includes: a support plate 9 welded to the workbench 2, and a lead screw 10 is threadedly installed on the support plate 9; a limiting plate 11 rotatably installed on the lead screw 10, and the bottom of the limiting plate 11 is in contact with the top of the workbench 2.

[0024] In this embodiment, the limiting mechanism is used to fix the position of the packaging board. In order to prevent the placement position of the packaging board from being inaccurate, the position of the limiting plate 11 needs to be adjusted. During the adjustment, the lead screw 10 is rotated. The lead screw 10 moves on the support plate 9, and the lead screw 10 drives the limiting plate 11 to move. In this way, the position of the packaging board can be limited by adjusting the position of the limiting plate 11, so that the packaging board can be placed in the accurate position during the folding work.

[0025] In a further preferred embodiment of the present utility model, the pressing mechanism includes: an electric telescopic rod 12 fixedly installed on the inner wall of the top of the frame 1, an installation block 13 is fixedly installed on the output rod of the electric telescopic rod 12, and a T-shaped groove is formed in the installation block 13; a clamping block 14 arranged on the T-shaped groove, and a pressing plate 15 is fixedly installed at the bottom of the clamping block 14.

[0026] In this embodiment, the pressing mechanism is used to fold the packaging board. Before use, a pressing plate 15 with a suitable width needs to be selected. The width of this pressing plate 15 should be the same as the bottom width of the finally folded packing box. When the pressing plate 15 needs to be installed, just insert the clamping block 14 on the pressing plate 15 into the T-shaped groove, and the installation is relatively convenient. When the packaging board needs to be folded, start the electric telescopic rod 12, and the electric telescopic rod 12 will drive the pressing plate 15 to move vertically, press the packaging board into the groove body 3. Under the blocking action of the two baffles 8 and multiple rollers, the crease part of the packaging board will react, so that the whole packaging board can be folded in a U shape, and the folding is relatively convenient.

[0027] In a further preferred embodiment of the present invention, a box body 16 is fixedly installed at the top of the frame 1, and the box body 16 is used to store pressing plates 15 of different sizes.

[0028] In this embodiment, by using the box body 16, it is convenient for personnel to store pressing plates 15 of various different specifications, so that when folding packing boxes of different specifications later, it is convenient to select a suitable pressing plate 15.

[0029] In a further preferred embodiment of the present invention, the clamping block 14 is set to be T-shaped, and the clamping block 14 is made of stainless steel.

[0030] In this embodiment, the stainless steel clamping block 14 has good corrosion resistance and durability, is not easy to rust, and has a good service life.

[0031] In a further preferred embodiment of the present invention, knobs are fixedly installed at the mutually remote ends of the two lead screws 10, and a plurality of anti-slip sheets are fixedly installed on the two knobs.

[0032] In this embodiment, through the combined use of the two knobs and the plurality of anti-slip sheets, it is convenient for personnel to rotate the two lead screws 10, and the convenience of operation can be improved.

[0033] In a further preferred embodiment of the present invention, support blocks are fixedly installed on the inner walls of both sides of the cavity 4, and the two support blocks are respectively rotatably connected to the two screw rods 6.

[0035] In summary, compared with the related art, in this solution, through the cooperative use of the biaxial motor 5, two screws 6, and two connecting blocks 7, the distance between the two baffles 8 can be adjusted according to the packaging board to be folded. The two limiting mechanisms can be used to clamp packaging boards of different widths, enabling the packaging board to be placed in a suitable position and not prone to positional deviation. Through the pressing mechanism, the packaging board can be pressed down and pressed into the groove body 3. Under the blocking action of the two baffles 8 and multiple rollers, the crease part of the packaging board will respond, enabling the entire packaging board to be folded in a U shape, which is relatively convenient for folding. Since the pressing plate 15 on the pressing mechanism can also be replaced according to the width of the packaging board, the device can be used to fold packaging boxes of different specifications, and has good versatility.
