Description

Technical Field

[0001] The present application relates to the technical field of packaging box processing, and in particular to a packaging box flattening device. Background Art

[0002] During the processing of packaging boxes, it is generally necessary to perform a leveling operation on them. Leveling can make the surface of the packaging box flat, avoiding problems such as unevenness, wrinkles or warping, ensuring the beautiful appearance of the packaging box, and the packaging box that has been leveled is easier to carry out subsequent processing and packaging procedures.

[0003] At present, during the leveling process of packaging boxes, the leveling roller is generally rolled on the surface of the packaging box in a horizontal state for leveling. However, since some packaging boxes themselves have a certain inclination angle, the leveling roller may easily act unevenly on the packaging box. Some areas may receive a stronger leveling force, while other areas may receive a weaker leveling force, resulting in inconsistent leveling effects. Utility Model Content

[0006] Preferably, the positioning mechanism comprises a limiting ring fixedly sleeved on the outer surface of the rotating shaft, and the outer surface of the limiting ring is provided with a plurality of limiting holes, and the position of the leveling roller can be adjusted to be in a stable state through the positioning mechanism.

[0007] Preferably, a screw button is threadedly connected to the inner surface of the concave plate, and the screw button is movably arranged with the limiting hole.

[0008] Preferably, the buffer mechanism comprises a bottom plate fixedly connected to the bottom of the fixed plate, and a guide cylinder is fixedly connected to the bottom of the bottom plate.

[0010] Preferably, the bottom of the slide rod is fixedly connected to a base, a roller shaft is fixedly penetrated through the inner side of the base, and the outer surface of the roller shaft is rotatably connected to the inner surface of the leveling roller.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] See also Figure 1-3 A packaging box leveling device comprises a device base 1, on which a leveling platform 2 is arranged, an electric slide rail 3 is arranged on the inner side of the device base 1, a moving frame 4 is installed on the electric slide rail 3, an electric push rod 5 is fixedly installed on the outer surface of the moving frame 4, an output end of the electric push rod 5 is fixedly connected with a concave plate 6, the inner surface of the concave plate 6 is rotatably connected with a rotating shaft 7 through a positioning mechanism, a fixed plate 11 is fixedly sleeved on the outer surface of the rotating shaft 7, a leveling roller 18 is movably installed below the fixed plate 11 through a buffer mechanism, and a heater 19 is arranged on the outer surface of the device base 1.

[0020] Through the above technical solution, when the device is in use, the packaging box is placed on the leveling platform 2, and the lower leveling roller 18 is moved down to a suitable position through the electric push rod 5. The two sets of leveling rollers 18 can be stabilized after adjusting the leveling angle in cooperation with the positioning mechanism, and finally the packaging box is rolled and leveled at a suitable inclination angle.

[0021] Specifically, the positioning mechanism includes a limiting ring 8 fixedly sleeved on the outer surface of the rotating shaft 7 , and a plurality of groups of limiting holes 9 are formed on the outer surface of the limiting ring 8 .

[0022] Through the above technical solution, the screw button 10 passes through different limiting holes 9 and is connected to the concave plate 6, so that the fixing plate 11 adjusted to the corresponding position can be stabilized.

[0023] Specifically, a screw button 10 is threadedly connected to the inner surface of the concave plate 6 , and the screw button 10 and the limiting hole 9 are movably arranged.

[0024] Through the above technical solution, the existence of the screw button 10 can ensure that the rotating shaft 7 passing through the fixing plate 11 is always in a fastened state with the concave plate 6, and no rotational deviation occurs.

[0025] Specifically, the buffer mechanism includes a bottom plate 12 fixedly connected to the bottom of the fixed plate 11 , and a guide tube 13 is fixedly connected to the bottom of the bottom plate 12 .

[0026] Through the above technical solution, four groups of guide tubes 13 are designed, which are respectively close to the four corners of the bottom plate 12, and play the role of guiding the sliding rod 14 to pass through.

[0027] Specifically, the inner surface of the guide tube 13 is slidably connected with a slide rod 14 , and the outer surface of the slide rod 14 is movably inserted into the inner surface of the bottom plate 12 , and the outer surface of the slide rod 14 is movably sleeved with a spring 15 .

[0028] Through the above technical solution, the spring 15 can smoothly apply the leveling roller 18 to the packaging box, thereby avoiding deformation or damage of the product due to excessive impact force.

[0029] Specifically, the bottom of the slide bar 14 is fixedly connected to a base 16 , and a roller shaft 17 is fixedly penetrated through the inner side of the base 16 . The outer surface of the roller shaft 17 is rotatably connected to the inner surface of the leveling roller 18 .

[0030] Through the above technical solution, the two sets of leveling rollers 18 can be adjusted to a suitable inclination angle to press against the packaging box, so as to evenly level it with a suitable force.

[0031] Working principle: When the device is leveling the packaging box, the packaging box is first placed on the leveling platform 2. Considering that some local areas on the packaging box may have a slight inclination, the completely flat leveling rollers 18 are likely to cause uneven action on the packaging box. Some areas may receive a stronger leveling force, while other areas may receive a weaker leveling force. At this time, the positions of the two sets of leveling rollers 18 can be adjusted, that is, the rotating shaft 7 is rotated in the concave plate 6 to drive the fixed plate 11 to rotate synchronously. During this process, the positions of the two sets of leveling rollers 18 under the bottom plate 12 will change until the two sets of leveling rollers 18 are adjusted to a suitable inclination angle. At this time, the screw button 10 can be passed through the limiting hole 9 at the corresponding position on the limiting ring 8 and screwed into the concave plate 6, thereby limiting the position between the rotating shaft 7 and the concave plate 6 to avoid deflection between the two. Then, the electric push rod 5 is turned on to push the two sets of leveling rollers 18 forward until It presses against the packaging box with appropriate force and moves the moving frame 4 forward through the electric slide rail 3. During this process, the slide rod 14 will move up along the guide tube 13 and compress the spring 15. The spring 15 can generate a reverse buffering force after compression and deformation, so as to smoothly apply the leveling roller 18 to the packaging box to avoid deformation or damage of the product due to excessive impact force at the moment of pressing. At the same time, the leveling force can be adjusted so that it always presses against the packaging box with a more appropriate force. The two sets of leveling rollers 18 can smoothly press against the packaging box for leveling operation. Finally, the heater 19 on the outside of the device seat 1 heats the air and provides hot air to dry the damp packaging box. It can quickly evaporate the moisture on the surface of the packaging box, restore it to a dry state, enhance the stability and strength of the packaging box, avoid damage to the packaging box during the leveling process, and effectively improve the stability of the leveling device.
