Description

Technical Field

[0001] The present application relates to the field of knife plate molds, and in particular to a material pressing mechanism, a high-speed cotton pasting machine including the material pressing mechanism, and a high-speed cotton pasting method implemented by the high-speed cotton pasting machine. Background Art

[0002] The flat die cutter is a very commonly used tool in the packaging industry. A blade is provided on the flat die cutter, and the blade is used to cut or indent the packaging material to meet the needs of use.

[0003] Usually, elastic materials are provided on the cutting plates on both sides of the blade of the blade. The elastic materials are foams. The elastic materials are attached to the cutting plates and are located on both sides of the blade, so that the blade is covered in the elastic materials. Only when the elastic materials are compressed during cutting, the blade is exposed. This arrangement can protect the blade and minimize the damage caused by the blade being hit during non-working hours. Secondly, after the blade cuts the packaging material, the compressed elastic materials are reset to lift the packaging material, so that the packaging material is separated from the blade.

[0004] Since a whole piece of foam needs to be cut into foam prefabricated blocks of appropriate sizes according to the required size, the bottom of the foam prefabricated block also needs to be sticky to facilitate sticking the foam prefabricated block to the flat die.

[0005] In the prior art, since adjacent foam prefabricated blocks may be partially connected, and the oil paper at the bottom of adjacent foam prefabricated blocks may be integrally or partially connected, when a foam prefabricated block is grabbed by the device, other connected foam prefabricated blocks may be moved, thereby changing the positions of other foam prefabricated blocks. When the device is operated automatically, the next process may have problems with the pasting accuracy. In response to this problem, the applicant has developed a material pressing mechanism, but in actual application, it is found that the existing material pressing mechanism has a fixed size and is difficult to apply to foam prefabricated blocks of different sizes.
