[0027] After the adhesive solution is thrown to the inner wall of the filter tank 1 under the action of centrifugal force, it is collected at the bottom of the filter tank 1 under the action of gravity and then discharged outward through the discharge pipe 4.
[0028] Further, referring to Figures 2-4 It is worth noting that the scraping mechanism for preventing impurities from blocking the filter holes of the separation cylinder 5 is also included.
[0029] The scraping mechanism includes a scraper 9 vertically arranged in the inside of the separation cylinder 5, one side of the scraper 9 being in contact with the inner wall of the separation cylinder 5.
[0030] Through the arrangement of the scraper 9, when the separation cylinder 5 is continuously rotated to separate the adhesive under the action of the motor 8, one side of the scraper 9 is in contact with the inner wall of the separation cylinder 5, which can effectively clean the inner wall of the separation cylinder 5 to a certain extent, so as to prevent impurities from blocking the filter holes of the separation cylinder 5 and enhance the separation effect of the separation cylinder 5 on the adhesive.
[0031] Further, referring to Figure 2 and Figure 3 It is worth noting that the scraping mechanism also includes a movable slot 10 horizontally arranged in the inner wall of the cover plate 2 and a movable block 11 slidingly arranged in the movable slot 10, a turnover connecting part being arranged between the movable block 11 and the scraper 9, and a push-pull part being arranged on one side of the cover plate 2.

[0033] Through the arrangement of the push-pull part, during the continuous rotation of the separation cylinder 5 to separate the adhesive, the telescopic rod of the electric cylinder 12 is reciprocatingly extended and retracted by the controller, so that the movable block 11 can slide back and forth in the inside of the movable slot 10 to make the scraper 9 intermittently contact the inner wall of the separation cylinder 5, thereby preventing the fixed scraper 9 from long-term contacting the inner wall of the separation cylinder 5 and increasing the wear of one side thereof.
[0034] Further, referring to Figure 3 and Figure 4As shown, it is worth noting that the turnover connecting part includes a transmission column 13 vertically rotating through the inner wall of the movable block 11 and a connecting column 14 fixed to the top end of the scraper 9, the connecting column 14 is detachably connected with the transmission column 13 through a bolt, the rod of the transmission column 13 is provided with an expansion slot, the expansion slot is provided with an elastic clamping piece, and the outer rod of the transmission column 13 is provided with a transmission assembly matched with the elastic clamping piece;

[0039] Conversely, when the scraper 9 moves away from the inner wall of the separation cylinder 5 under the action of the electric cylinder 12, the transmission gear 16 again passes through the transmission tooth plate 17 and acts on the movable sleeve 15 to rotate counterclockwise, so that the plurality of connecting teeth 20 successively contact the inclined edge of the expansion block 18, so that the expansion block 18 is repeatedly extruded and compressed in the expansion slot and the buffer spring 19 is compressed and deformed, so that the transmission column 13 is not disturbed during the rotation of the movable sleeve 15, and the relative fixation of the scraper 9 is maintained, so that the scraper 9 does not turn over when moving away from the inner wall of the separation cylinder 5;
