Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] The present utility model provides a spraying device as Figures 1 - 8 shown, including a support frame 1 and a spraying box 2 installed on the support frame 1. A feed inlet is provided on one side of the bottom of the spraying box 2, and a discharge outlet is provided on the other side. A feeding member for supplying liquid to the spraying member is also provided in the spraying box 2. A nip roller 15 is rotatably installed on one side of the spraying box 2 near the feed inlet. A recovery assembly is provided on the support frame 1, and a motor 12 for driving the nip roller 15 to rotate is fixed on one side of the spraying box 2;

[0030] A scraping mechanism 13 is also provided on one side of the spraying box 2, and the scraping mechanism 13 includes an upper scraping plate 131 and a lower scraping plate 132 symmetrically arranged in the discharge outlet, and an adjusting member for driving the upper scraping plate 131 and the lower scraping plate 132 to move relatively. A gap for discharging industrial filter cloth is left between the upper scraping plate 131 and the lower scraping plate 132.

[0031] Specifically, as Figures 2 - 7 shown, the adjusting member includes two fixing blocks 133 symmetrically fixed on one side of the spraying box 2. A bidirectional threaded rod 134 is rotatably installed on each of the two fixing blocks 133, and the bottom ends of the two bidirectional threaded rods 134 are rotatably connected to the top of the support frame 1. Moving blocks 135 are provided on both sides of the upper scraping plate 131 and the lower scraping plate 132, and the moving blocks 135 are threadedly engaged with the bidirectional threaded rod 134. Adjusting handwheels 138 are installed at the top ends of the two bidirectional threaded rods 134.

[0032] When spraying industrial filter cloth, first insert the industrial filter cloth from the feed inlet, and then bypass the biting roller 15 and the guiding member in sequence, and then pass through the discharge outlet. Subsequently, drive the biting roller 15 to rotate through the motor 12 to bite the industrial filter cloth, so that the industrial filter cloth moves under the action of the guiding member (the moving direction is as shown by the arrow in Figure 8 ), and during the moving process, feed the material to the spraying member through the feeding member, and spray the upper surface and the lower surface of the industrial filter cloth simultaneously through the spraying member. After spraying, the industrial filter cloth is discharged from the discharge outlet;

[0033] And when discharging, the upper scraper 131 and the lower scraper 132 respectively scrape the paint on the upper surface and the lower surface of the industrial filter cloth evenly, so that the excess paint falls into the recycling component for recycling, so as to facilitate the even spraying of the industrial filter cloth, and can recycle the excess paint, reduce the loss of paint, and save the spraying cost;

[0034] At the same time, when the upper scraper 131 and the lower scraper 132 scrape the paint on the upper surface and the lower surface of the industrial filter cloth evenly, the two-way threaded rod 134 can be rotated by adjusting the hand wheel 138, so that the two-way threaded rod 134 drives the upper scraper 131 and the lower scraper 132 to move away from or close to each other through the moving block 135, so as to adjust the size of the gap between the upper scraper 131 and the lower scraper 132, so that the gap between the upper scraper 131 and the lower scraper 132 can be adjusted according to the thickness of the industrial filter cloth, which is beneficial to the upper scraper 131 and the lower scraper 132 to scrape the industrial filter cloth of different thicknesses evenly, and then facilitate the spraying process of the industrial filter cloth of different thicknesses.

[0035] Regarding the above-mentioned spraying member, as shown in Figure 4 , the spraying member includes two spraying plates 14 symmetrically installed at the inner top of the spraying box 2, and nozzles facing the industrial filter cloth are installed on the opposite sides of the two spraying plates 14.

[0036] When spraying the industrial filter cloth, the feeding member transports the paint into the two spraying plates 14, and then sprays the paint onto the upper surface and the lower surface of the industrial filter cloth through the nozzles to achieve the spraying of the industrial filter cloth.

[0037] As shown in Figures 1 - 4 , the feeding member includes a storage tank 7 and a delivery pump 8 installed at the top of the spraying box 2. A pipeline is connected between the feeding end of the delivery pump 8 and the storage tank 7, and a delivery pipe 9 is connected to the discharging end of the delivery pump 8. A tee joint 10 is installed at one end of the delivery pipe 9, and the other two ends of the tee joint 10 are both connected with branch pipes 11, and one ends of the two branch pipes 11 are respectively communicated with the interiors of the two spraying plates 14.

[0038] When the feeding part feeds the spraying plate 14, the paint can be first added into the storage tank 7, and then the paint in the storage tank 7 is sucked out by the delivery pump 8, and the paint is simultaneously fed into the two spraying plates 14 through the cooperation of the delivery pipe 9, the three-way joint 10 and the branch pipe 11, so as to realize the feeding of the spraying plate 14.

[0039] As Figure 3 and Figure 4 shown, the guiding part includes a guiding roller 17, a tensioning roller 18 and two conveying rollers 16 rotatably installed in the spraying box 2. The guiding roller 17 is on one side of the discharge port. The two conveying rollers 16 are symmetrically distributed on both sides of the two spraying plates 14, and the tensioning roller 18 is located on one side of the guiding roller 17.

[0040] During spraying, the industrial filter cloth is guided in by the biting roller 15, and sequentially wound around the two conveying rollers 16 and the tensioning roller 18, and finally the industrial filter cloth is guided to the discharge port by the guiding roller 17. When the industrial filter cloth moves, the two conveying rollers 16, the guiding roller 17 and the tensioning roller 18 rotate driven by the industrial filter cloth to guide the industrial filter cloth. At the same time, the tensioning roller 18 tensions the industrial filter cloth to ensure the normal movement of the industrial filter cloth and avoid the phenomenon of slipping due to insufficient tension of the industrial filter cloth, which is beneficial to the efficient spraying of the industrial filter cloth.

[0041] Regarding the above-mentioned recovery component, as Figures 1 - 4 shown, the recovery component includes a liquid collecting tank opened on the top of the support frame 1, and a collecting box 4 and a reflux pump 5 fixed in the support frame 1. A filter screen 3 is installed in the liquid collecting tank. The top of the collecting box 4 is connected with a blanking pipe communicated with the liquid collecting tank, and a pipeline is connected between the collecting box 4 and the reflux pump 5. One end of the reflux pump 5 is connected with a reflux pipe 6 communicated with the storage tank 7.

[0042] When the upper scraper 131 and the lower scraper 132 scrape off the excess paint on the industrial filter cloth, the paint falls into the liquid collecting tank. At this time, after the paint is filtered by the filter screen 3, it is discharged into the collecting box 4 through the blanking pipe, and then the paint collected in the collecting box 4 is pumped out by the reflux pump 5 and sent into the storage tank 7 through the reflux pipe 6, so as to realize the recycling of the paint.

[0043] Furthermore, as Figures 3 - 7 shown, arc-shaped transition is formed at the back side of one end of the upper scraper 131 and the lower scraper 132 to form a scraping part. When the upper scraper 131 and the lower scraper 132 scrape the excess paint on the industrial filter cloth evenly, the arc-shaped scraping part can guide the paint, which is beneficial to the paint falling into the liquid collecting tank and convenient for the recovery of the paint.

[0044] In addition, in an embodiment, as Figures 5 - 7As shown, connectors are provided between the upper scraping plate 131 and the moving block 135, and between the lower scraping plate 132 and the moving block 135. The connector includes a connecting plate 136 fixed to one side of the upper scraping plate 131 and the lower scraping plate 132. One end of the connecting plate 136 is provided with a connecting block 139. A connecting groove 1310 for inserting the connecting block 139 is formed on one side of the moving block 135. A locking screw 137 is screwed on the moving block 135, and a threaded hole for screwing the locking screw 137 is provided on the connecting block 139.

[0045] When the upper scraping plate 131 or the lower scraping plate 132 needs to be disassembled, first unscrew the locking screw 137 from the threaded hole, and then pull the upper scraping plate 131 or the lower scraping plate 132, so that the connecting plate 136 drives the connecting block 139 to move out of the connecting groove 1310, thereby realizing the disassembly of the upper scraping plate 131 or the lower scraping plate 132 from between the two moving blocks 135. Subsequently, clean or replace the upper scraping plate 131 or the lower scraping plate 132. After cleaning or replacement, insert the upper scraping plate 131 or the lower scraping plate 132 between the two moving blocks 135. At this time, the connecting block 139 at one end of the connecting plate 136 is inserted into the connecting groove 1310, and then screw the locking screw 137 into the threaded hole to screw and fix the connecting block 139, thereby realizing the installation of the upper scraping plate 131 or the lower scraping plate 132, and thus realizing the quick disassembly and assembly of the upper scraping plate 131 or the lower scraping plate 132, facilitating the cleaning or replacement of the upper scraping plate 131 or the lower scraping plate 132, being beneficial to scraping the coating of the industrial filter cloth evenly, and further realizing the uniform spraying of the industrial filter cloth.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
