Description

Technical Field

[0001] The present invention relates to the technical field of carton packaging, and more specifically to a packaging device for automatically folding cartons. Background Art

[0002] In the modern era with a high degree of industrialization, the production speed of various products has been greatly improved, so the packaging of products using cartons must also be faster. Under the existing technology, packaging equipment with automatic folding of cartons is used to automatically and quickly pack cartons. Generally, this automatic folding and sealing machine will work with the assembly line. When working, it is only necessary to fold the four bendable panels formed on the bottom surface of the carton, put the items in, and input them into the conveying track driven by the belts on both sides. The carton folding device on the upper side of the sealing machine is started, and the folding and sealing are completed at one time. The use of automatic folding and sealing machines can speed up the packaging of cartons.

[0003] The automatic folding and sealing of boxes in the prior art still has the following shortcomings in practice:

[0004] First, after the automatic folding and sealing machine in the prior art has taped the carton, the pressure of the roller folding device on the original machine is relatively low in order to cooperate with the movement and pressure of the carton. Therefore, after the carton is separated from the roller, the tape taped on the carton may not be tightly attached to the carton, which will affect the subsequent tape sealing effect of the carton. The automatic folding and sealing machine in the prior art does not have a device that can make the tape precisely fit the carton.

[0005] Secondly, the automatic folding and sealing machine under the existing technology needs to slightly tilt the folding plate of the carton inwards before feeding the carton into the machine for folding. This effect is generally assisted by manual operation, which requires a certain amount of manpower. In addition, the automatic folding and sealing machine under the existing technology does not have the function of cleaning the surface of the carton folding plate before folding, which is easy to affect the subsequent lamination of the tape on the surface of the carton folding plate;

[0006] Therefore, it is necessary to provide a packaging device for automatically folding cartons to solve the above problems. Summary of the invention

Finally, the pressing rollers on both sides are pressed against the adhesive tape sealing parts on both sides of the carton with a certain pneumatic pressure, and move up and down under the control of the servo electric cylinder. Under the up and down rolling movement of the pressing rollers, the adhesive tape on the carton can be pressed against the carton again, so as to prevent the adhesive tape from falling off due to loose adhesion.

At the same time, the dust on the folding plate of the carton will be blown away while the fan is blowing, so as to achieve a good cleaning effect. When the carton moves between the mounting shells, the second motor drives the lead screw shaft to rotate, and the rotation of the lead screw shaft drives the threaded shaft sleeves on both sides to move closer to each other, and at the same time drives the mounting shell to clamp the carton, and under the drive of the first motor, the rotating shaft drives the transmission belt to operate, thereby driving the clamped carton to move.
