[0019] See also Figure 1 - Figure 5The figure shows an exhaust filter device for a coating machine, comprising a coating machine body 1, a coating drum 2 being rotatably connected to the inside of the coating machine body 1, a vent 3 being provided inside the coating machine body 1 near the coating drum 2, a dust box 4 being fixedly connected to the top of the coating machine body 1 near the vent 3, a mounting groove 17 being provided inside the dust box 4, a magnetic block 5 being fixedly connected to the inner side of the mounting groove 17 near the bottom, a mounting block 6 being magnetically attracted to the side of the magnetic block 5 near the mounting groove 17, a dust bag 7 being fixedly connected to the side of the mounting block 6 near the mounting groove 17, a sealing assembly being provided on one side of the dust box 4, the sealing assembly comprising a sealing block 8, which is embedded in the mounting groove 17, a mounting plate 9 being fixedly connected to the side of the sealing block 8 away from the mounting groove 17, and the mounting plate 9 abuts against one side of the dust box 4.

[0020] During operation, the raw materials are placed inside the coating drum 2, and the coating machine body 1 is started to drive the coating drum 2 to rotate, thereby coating the raw materials. During the processing, hot air is blown in along the vent 3, and the hot air will blow around the outside of the coating drum 2 and out from the other end of the vent 3. Impurities will be mixed in the blown hot air, and the impurities will enter the dust collecting bag 7 along the mounting block 6 and be collected at the bottom of the dust collecting bag 7. The hot air is blown out from the position of the dust collecting bag 7 away from the vent 3. The dust collecting bag 7 is installed in the mounting groove 17 by magnetic attraction of the mounting block 6 and the magnetic block 5, which solves the problem of complex dust removal structure and difficult maintenance in the past, and improves the convenience during maintenance.

[0021] See also Figure 2 - Figure 4 In the figure, a positioning groove 10 is provided on the outside of the sealing block 8, and a positioning block 11 is embedded in the positioning groove 10. A telescopic groove 14 is provided inside the dust box 4 near the positioning groove 10. The positioning block 11 is slidably connected to the inside of the telescopic groove 14. An extension shell 13 is fixedly connected to the outside of the dust box 4. The inside of the extension shell 13 is connected to the telescopic groove 14. A spring 12 is sleeved on the outside of the positioning block 11 away from the positioning groove 10, and the spring 12 is arranged inside the telescopic groove 14.

[0022] During operation, after the dust bag 7 has been used for a period of time, the positioning block 11 can be pulled to disengage the positioning block 11 from the positioning groove 10, thereby removing the sealing block 8 and the mounting plate 9. At this time, a new dust bag 7 can be replaced, and the sealing block 8 is inserted into the mounting groove 17. The spring 12 will push the positioning block 11 into the positioning groove 10, thereby fixing the sealing block 8 inside the mounting groove 17, achieving the effect of quickly replacing the dust bag 7, solving the problem of the dust bag 7 being loosely installed when the dust bag 7 is installed inside the mounting groove 17 only by magnetic attraction, and improving the stability of the installation of the dust bag 7.

[0023] See also Figure 1 、 Figure 2 and Figure 5 In the figure, the positioning block 11 is arranged with an oblique surface on the side close to the mounting plate 9 away from the end of the spring 12, the vent 3 is arranged in a "U" shape, a feed port 15 is opened on the top of the coating machine body 1, and the feed port 15 is connected to the coating drum 2. The bottom of the coating machine body 1 is fixedly connected with a support leg 16, and there are two groups of support legs 16 arranged symmetrically.

[0024] During operation, when the sealing block 8 is inserted, the sealing block 8 will first contact the beveled surface of the positioning block 11. At this time, the positioning block 11 will squeeze the spring 12, allowing the positioning block 11 to shrink into the telescopic groove 14. When the sealing block 8 is fully inserted into the installation groove 17, the spring 12 will push the positioning block 11 to embed into the positioning groove 10, thereby fixing the sealing block 8. When the equipment is in use, the support legs 16 can provide sufficient support force and stability, thereby improving the efficiency of replacing the dust bag 7.

[0025] Working principle: put the raw materials into the coating drum 2, start the coating machine body 1 and let the coating machine body 1 drive the coating drum 2 to rotate, so as to coat the raw materials. During the processing, the hot air is blown in along the vent 3, and the hot air will blow around the outside of the coating drum 2 and out from the other end of the vent 3. Impurities will be mixed in the blown hot air, and the impurities will enter the dust collecting bag 7 along the mounting block 6 and be collected at the bottom of the dust collecting bag 7. The hot air is blown out from the position of the dust collecting bag 7 away from the vent 3. The dust collecting bag 7 is installed in the mounting groove 17 by the magnetic attraction of the mounting block 6 and the magnetic block 5, which solves the problem of complex maintenance difficulty of the previous dust removal structure and improves the convenience of maintenance. After the dust collecting bag 7 has been used for a period of time, the positioning block 11 can be pulled to disengage the positioning block 11 from the inside of the positioning groove 10, thereby removing the sealing block 8 and the mounting plate 9, and then a new one can be replaced. When the dust bag 7 is replaced, the sealing block 8 will first contact the oblique cut surface of the positioning block 11. At this time, the positioning block 11 will squeeze the spring 12, allowing the positioning block 11 to retract into the telescopic groove 14. When the sealing block 8 is fully inserted into the mounting groove 17, the spring 12 will push the positioning block 11 to embed into the positioning groove 10, thereby fixing the sealing block 8. When the equipment is in use, the support legs 16 can provide sufficient support force and stability, thereby improving the efficiency of replacing the dust bag 7.
