[0009] By adopting the above technical solution, during the process of the spiral push plate rotating to push the adhesive to move, since the pitch of the spiral push plate gradually decreases, and as the adhesive follows the spiral push plate to move, the pressure on the adhesive will gradually increase, achieving the effect of quickly squeezing the adhesive out of the cylinder wall during the process of moving in the filter cylinder.

[0010] In a preferred example, the utility model can be further configured as follows: a cylinder wall of the filter cylinder is provided with a plurality of filter holes arranged in a uniform array, and both ends of the filter holes are provided with rounded corners.

[0011] By adopting the above technical solution, the filter holes are used to filter the solid matter in the adhesive, and the rounded corners are set to prevent the filter holes from scratching the silicone scraper, thereby achieving the effect of increasing the service life of the silicone scraper.

During the rotation of the sleeve, the scraper plate moves on the surface of the storage cylinder and the filter cylinder, thereby achieving the effect of gathering the adhesive filtered out from the surface of the filter cylinder, and the positioning ring is used to improve the stability of the scraper plate during rotation.

[0014] In a preferred example, the utility model can be further configured as follows: the side wall of the scraper plate fits with the outer wall of the storage cylinder and the outer wall of the filter cylinder, and both side edges of the scraper plate are provided with bevel angles.

[0015] By adopting the above technical solution, the surfaces of the filter cylinder and the storage cylinder are scraped during the rotation of the scraper plate, so as to achieve the purpose of gathering the filtered adhesive.

[0016] In a preferred example, the utility model can be further configured as follows: a sealing plate sleeved on the outer surface of the driving shaft is provided at the rear end of the two-way end of the three-way pipe, and a rotating sealing ring is provided at the connection between the sealing plate and the driving shaft.

[0019] 1. In the present invention, in the process of the spiral push plate pushing the adhesive to move, the speed of pushing the adhesive to move at the position where the spiral push plate has a large pitch is greater than that at the position where the spiral push plate has a small pitch, and then in the process of the adhesive following the movement of the spiral push plate, the pressure on the adhesive will gradually increase, so that the adhesive will be quickly squeezed out from the cylinder wall during the process of moving in the filter cylinder, effectively increasing the speed of the adhesive being discharged from the filter cylinder, and avoiding the problem of the adhesive being bonded and solidified inside the filter hole of the filter cylinder;

DETAILED DESCRIPTION

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] Example:

[0030] Reference Figure 1-Figure 5 The utility model discloses a filtering device for adhesive production, comprising a tee pipe 1, a hexagonal flange 13 is provided at the upper end of the one-way portion 11 of the tee pipe 1, a filter cartridge 2 is fixedly connected to the front end of the two-way portion of the tee pipe 1, a storage cartridge 3 is connected to the front section of the filter cartridge 2 by a thread, a driving motor 4 is fixedly connected to the rear end of the two-way portion of the tee pipe 1, a driving shaft 41 of the driving motor 4 is inserted into the interior of the tee pipe 1 and passes through the storage cartridge 3, a cleaning scraper 5 is installed on the portion of the driving shaft 41 passing through the storage cartridge 3 by a key pin, and a spiral push plate 6 is provided on the outer surface of the portion of the driving shaft 41 located inside the tee pipe 1 and the storage cartridge 3.

[0031] In the present embodiment, when in use, the discharge pipe of the reaction cylinder for preparing the adhesive is connected to the one-way portion 11 of the tee 1 through the hexagonal flange 13, and then the adhesive is introduced into the one-way portion 11 of the tee 1. At this time, the driving motor 4 is driven to rotate the driving shaft 41, and during the rotation of the driving shaft 41, the spiral push plate 6 pushes the adhesive box storage cylinder 3 to move. Since the adhesive is continuously transported to the inside of the tee 1, the adhesive will overflow through the wall of the filter cylinder 2, and the impurities therein cannot pass through the wall of the filter cylinder 2, and are dragged to the inside of the storage cylinder 3 by the spiral push plate 6, thereby achieving the effect of filtering and separation, and the cleaning scraper 5 follows the rotation of the driving shaft 41 to gather the adhesive overflowing from the wall of the filter cylinder 2, thereby achieving the purpose of quickly dropping the adhesive from the surface of the filter cylinder 2.

[0033] In this embodiment, during the process of the spiral push plate 6 rotating to push the adhesive to move, since the pitch of the spiral push plate 6 gradually decreases, the speed of pushing the adhesive to move at the position where the pitch of the spiral push plate 6 is large is greater than that at the position where the pitch is small. Therefore, during the process of the adhesive following the movement of the spiral push plate 6, the pressure on the adhesive will gradually increase, so that the adhesive will be quickly squeezed out from the wall of the filter cartridge 2 during the movement in the filter cartridge 2, effectively increasing the speed at which the adhesive is discharged from the filter cartridge 2 and avoiding the effect of the adhesive being bonded and solidified inside the filter cartridge 2. By setting the silicone scraper 61, the outer edge of the spiral push plate 6 is fitted with the inner wall of the filter cartridge 2, thereby avoiding the problem of adhesive adhering to the inner wall of the filter cartridge 2.

[0037] In this embodiment, the sleeve 51 is fixedly connected to the drive shaft 41 by a key pin, and the sleeve follows the drive shaft 41 to rotate during the rotation of the drive shaft 41. During the rotation of the sleeve, the scraper plate 52 moves on the surface of the storage cylinder 3 and the filter cylinder 2, thereby achieving the effect of gathering the adhesive filtered out from the surface of the filter cylinder 2, so as to facilitate the collection of the adhesive.

[0038] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the side wall of the scraper plate 52 is in contact with the outer wall of the storage cylinder 3 and the outer wall of the filter cylinder 2 , and both side edges of the scraper plate 52 are provided with bevels 54 .

[0039] In this embodiment, the surfaces of the filter cartridge 2 and the storage cartridge 3 are scraped during the rotation of the scraper plate 52 to gather the filtered adhesive, and the positioning ring 53 is used to improve the stability of the scraper plate 52 during rotation. At the same time, the setting of the bevel 54 facilitates the purpose of scraping off the adhesive on the surface of the filter cartridge 2.
