[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The embodiment of the utility model provides a technical solution: a dust-proof powder filling vacuum equipment, comprising a fixed box 1, an air pump 2 and a dust-proof component 3, the air pump 2 is fixedly connected to the inside of the fixed box 1, the bottom of the air pump 2 is fixedly connected with the dust-proof component 3, the dust-proof component 3 comprises an air suction nozzle 4, a pressing block 5, a splint 6 and a filter 7, the air suction nozzle 4 is fixedly connected to the bottom of the air pump 2, the pressing block 5 is located at the bottom of the fixed box 1 and is slidably connected to the fixed box 1 up and down, the splint 6 is located on both sides of the air suction nozzle 4 and is slidably connected to the pressing block 5, the upper surface of the splint 6 is slidably connected to the bottom of the fixed box 1, and the filter 7 is fixedly connected to the end face of the air suction nozzle 4.

[0023] As a further improvement, the vacuum nozzle 4 is distributed in a flat shape, and a plurality of evenly distributed air holes 8 are provided at the edge of the vacuum nozzle 4. A sealing groove 9 is provided on the side wall of the vacuum nozzle 4. By adopting a flat-shaped vacuum nozzle 4, it is convenient to fully contact with the vacuum bag, and combined with a plurality of evenly distributed air holes 8, the efficiency of vacuuming the vacuum bag is improved, thereby preventing dust from escaping from the vacuum bag.

[0024] As a further improvement, the end of the air hole 8 is inclined at 45°, the filter screen 7 is embedded in the air hole 8, and the air hole 8 is also filled with filter cotton 10. By designing the air hole 8 to be inclined at 45°, the dust filtered out from the surface of the filter screen 7 can be easily dropped, and the exhaust nozzle 4 can be easily cleaned. In combination with the filter cotton 10 filled in the air hole 8, dust can be prevented from entering the vacuum fan 2, thereby improving the working stability of the vacuum fan.

[0025] As a further improvement, a pair of side wall surfaces of the pressing block 5 are provided with strip holes 11, and the inner wall of the side wall of the pressing block 5 with the strip holes 11 is fixedly connected with a sliding block 12. By providing the strip holes 11 with the bag sliding block 12 on the side wall of the pressing block 5, it is convenient to drive the splint 6 for sliding connection, so as to facilitate clamping and sealing the surface of the vacuum bag.

[0026] As a further improvement, the side wall of the clamping plate 6 is provided with an inclined sliding groove 13, and the sliding block 12 is embedded in the sliding groove 13 and is slidably connected to the sliding groove 13. By providing the inclined sliding groove 13 on the side wall of the clamping plate 6, it is convenient for the pressure block 5 to move forward and backward when sliding up and down, so as to clamp the vacuum bag.

[0027] Specifically, the inner wall of the splint 6 is provided with a raised sealing strip 14, and the sealing strip 14 is interlocked and connected with the sealing groove 9. By providing a raised sealing strip 14 on the inner wall of the splint 6, it is convenient to fit closely with the exhaust nozzle 4 after the splint 6 is closed, thereby improving the working efficiency of the exhaust fan 2.

[0028] When the utility model is in use, the filled vacuum bag is directly placed in the supporting barrel without the need to use a barrel cover to fix it. When the vacuum bag moves to the bottom of the vacuum pump 2, the electric push rod on the top of the fixed box 1 is used to push the fixed box 1 to move downward, and the pressing block 5 contacts and slides with the top of the supporting barrel. The sliding block 12 pushes the pressing plate to move inward, and the vacuum bag opening is tightly pressed against the surface of the vacuum nozzle 4. The vacuum pump 2 can extract the air in the vacuum bag through the vacuum nozzle 4, thereby improving the working efficiency of the vacuum pumping equipment.

[0029] The problem solved by the utility model is that the bag opening needs to be tied and fixed to the side wall of the dustproof tube with a cable tie. Although the sealing of the connection can be effectively guaranteed, the working efficiency is too low, especially in the automated production process, which seriously affects the production efficiency and brings inconvenience to the production and processing. The utility model provides a dustproof component under the vacuum pump, and utilizes a sliding connection of a pressure block and a clamping plate to quickly clamp and seal the vacuum bag opening, thereby improving the vacuum pump's vacuuming efficiency. At the same time, the filter net and filter cotton inside the vacuum nozzle can filter dust during vacuuming, thereby preventing dust from entering the vacuum pump during vacuuming, thereby improving the working stability and service life of the vacuum pump.
