Problems solved by technology
[0003] However, through the above-mentioned processes, the PP filter paper is taken and placed to different machines many times, and the PP filter paper needs to be positioned and adjusted in the machine, resulting in low efficiency in the forming process of folding paper and glue injection. The positioning error between them will easily lead to the folding of PP filter paper and poor glue injection effect, and the folding and bonding of PP filter paper will not be firm, which will affect the filtering effect

Embodiment Construction
[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0029] Such as Figure 1-4 As shown, a kind of PP filter paper molding processing method of the preferred embodiment of the present invention comprises the following steps:
[0030] Import: import the PP filter paper 100 into the origami mechanism in a compressed state;
[0031] Origami: 2 pairs of PP filter paper 100 origami by jackknife;
[0032] Softening: use the folding knife 2 to send the PP filter paper 100 into the pressing plate 3 and heat it to soften the creases;
[0033] Squeeze out: push out the PP filter paper 100 after being pressed and squeezed, and send it out together with the PP filter paper 100 in front;
[0034] Glue injection: convey the filter pa...

The invention relates to the technical field of filter paper filtration, and discloses a PP filter paper molding processing method. The method includes the following steps that leading-in is conducted, and PP filter paper is led into a paper folding mechanism in a compression state; paper folding is carried out, and the PP filter paper is folded with a folding knife; softening is performed, and the PP filter paper is delivered to the position below a pressing plate to be heated with the folding knife so as to soften folding marks; squeezing and pushing-out are carried out, the PP filter paperis pushed out after being compressed and squeezed and then is conveyed out together with PP filter paper at the front side after compression; glue injection is conducted, the filter paper is conveyedand further tensioned through a tensioning mechanism, double-faced hot melt glue injection is conducted on the PP filter paper in the direction perpendicular to the folding marks and a plurality of rows of glue lines are formed; and cooling shaping is carried out, the PP filter paper is folded along the folding marks, and after the glue lines are cooled by a first air cooling system, the PP filterpaper is delivered to a shaping mechanism for shaping. By adoption of the PP filter paper molding processing method, the working procedures of folding and glue injection can be completed quickly, andthe effect is excellent.
Description
technical field [0001] The invention relates to the technical field of filter paper processing, in particular to a forming and processing method for PP filter paper. Background technique [0002] Filter paper is a commonly used filter material for filters, and its performance directly affects the filtering effect of the filter. In order to improve the filtration efficiency of the filter paper, the filter paper is usually folded during the production process so that the formed filter paper has wavy creases, thereby expanding the filtration area of the filter paper per unit area. For example, in some high-efficiency filters, low-resistance, high-efficiency, high-strength PP filter paper (that is, PP sub-high-efficiency filter paper) will be used as its filter material, and in order to further improve the filtration efficiency, paper folding machines, glue injection machines, The sizing machine performs folding, glue injection, and sizing treatment on the PP filter paper in ...
