Abstract
Description
Technical Field
[0001] The present application relates to the technical field of feeding devices, and in particular to a feeding device for vacuum mixing equipment. Background Art
[0002] The feeding device of vacuum mixing equipment is vacuum loader. Vacuum loader, also known as vacuum conveyor, is a dust-free closed pipeline conveying equipment that uses vacuum pump to generate vacuum suction to convey granular and powdered materials.
[0003] Its specific structure is: it includes a vacuum pump, a compressed air backblowing device, a vacuum hopper and a feed pipe. The vacuum pump and the compressed air backblowing device are installed in the vacuum hopper. One end of the feed pipe is installed at the feed port of the vacuum hopper, and the other end is installed on the charging barrel. By starting the vacuum pump and the compressed air backblowing device, the vacuum pump pumps the material in the charging barrel into the vacuum hopper through the feed pipe, and then the compressed air backblowing device blows the material to the discharge port of the vacuum hopper to flow out, thus completing the material transportation.
[0004] However, in the prior art, manufacturers usually use customized loading barrels to facilitate recording the amount of material input each time. The customized loading barrels are composed of a barrel body, a barrel cover and a discharge pipe. Since the volume of the barrel body and the diameter of the discharge pipe of the customized loading barrels of each manufacturer are different, the feed pipe of the loading device cannot completely conform to the discharge pipe of the loading barrel, resulting in air leakage at the discharge pipe and the feed pipe when the vacuum pump transports the material, affecting the transportation efficiency. In order to solve this technical problem, the prior art will stuff a circle of cotton cloth on the inside of the discharge pipe and then stuff the feed pipe in. Although this can prevent air leakage in some positions, since the manually stuffed cotton cloth does not necessarily ensure that it is laid evenly in every place, there will still be air leakage in some positions. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide a feeding device for vacuum mixing equipment, which is used to solve the technical problem of air leakage at the connection between the feed pipe and the discharge pipe in the existing technology.
[0006] The above-mentioned purpose of the present application is achieved through the following technical solutions: a feeding device of a vacuum mixing equipment, comprising a vacuum hopper, a vacuum pump and a compressed air back-blowing device installed in the vacuum hopper, and a feed pipe connected to the feed port of the vacuum hopper, one end of the feed pipe being threadedly connected to the vacuum hopper, and the other end being provided with an adjustment clamp for making the feed pipe adapt to the discharge pipes of different apertures of the charging barrel.
[0007] Furthermore, the adjustment fixture includes a fixed ring fixedly connected to the circumference of the feed pipe and an arc-shaped clip slidably connected to the fixed ring. The feed pipe passes through the fixed ring, and a sliding groove is provided on the fixed ring. The arc-shaped clip is slidably connected to the fixed ring through the sliding groove. There are two arc-shaped clips, which are located on both sides of the outside of the feed pipe and are arranged opposite to each other. The diameter of the fixed ring is larger than the diameter of the feed pipe.
[0008] By adopting the above technical solution, after the vacuum hopper is installed on the vacuum mixing equipment, when the feed pipe needs to be connected to the discharge pipe of the charging barrel, the inner diameter of the discharge pipe is larger than the outer diameter of the feed pipe. The staff slides the arc-shaped clamp outward and then pushes the feed pipe into the discharge pipe so that the fixed ring blocks the discharge port of the discharge pipe. Then, the arc-shaped clamp is slid to press the outer wall of the discharge pipe. In this way, the feed pipe can be used normally when encountering different diameters of discharge pipes, and the fixed ring blocks the discharge port of the discharge pipe to prevent air leakage, thereby ensuring the transportation efficiency of the vacuum pump in transporting materials, so that the feed pipe can adapt to different diameters of discharge pipes, and improves the applicability and practicality of the feed pipe.
[0009] Furthermore, fixing devices for fixing the arc-shaped clips are provided on both sides of the adjustment clamp.
[0010] Furthermore, the fixing device includes fixing plates fixedly connected to both sides of the fixing ring, connecting plates respectively fixedly connected to the sides of the two arc-shaped clips facing away from each other, and fixing bolts passing through the fixing plates and the connecting plates. The fixing plates are provided with a plurality of threaded holes, and the connecting plates are provided with a plurality of connecting holes corresponding to the threaded holes. The fixing bolts pass through the fixing plates and the connecting plates in sequence through the threaded holes and the connecting holes.
[0011] By adopting the above technical solution, although the setting of the clamp is adjusted so that the feed pipe can adapt to the diameters of different discharge pipes, after the sliding arc clamp presses the outer wall of the discharge pipe, if the staff lets go of the hand, the impact force generated by the airflow during transportation by the vacuum pump will cause the feed pipe to separate from the discharge pipe. If the staff keeps pressing the arc clamp, the processing time is long, and keeping pressing the arc clamp will increase the staff's workload. The setting of the fixing device solves this technical problem. After the staff slides the arc clamp to press the outer wall of the discharge pipe, they pick up the fixing bolt and align it with the threaded hole and the connecting hole, and then screw in the fixing bolt so that the fixing bolt passes through the fixing plate and the connecting plate to limit the freedom of the arc clamp and fix it. In this way, the pressure exerted by the arc clamp on the outer wall of the discharge pipe will not disappear because the staff lets go of the hand, thereby preventing the impact force generated by the airflow during transportation by the vacuum pump from causing the feed pipe to separate from the discharge pipe, making it more convenient for the staff to use the feed pipe.
[0012] Furthermore, an auxiliary device for preventing the inlet pipe from separating from the outlet pipe is provided on the side of the two arc-shaped clips facing away from each other.
[0013] Furthermore, the auxiliary device includes an auxiliary screw threadedly connected to the arc-shaped clamping piece, and the auxiliary screw passes through the arc-shaped clamping piece and abuts against the outer wall of the discharge pipe.
[0014] By adopting the above technical solution, although the setting of the fixing device can prevent the impact force generated by the airflow during transportation by the vacuum pump from causing the feed pipe to separate from the discharge pipe, the feed pipe needs to bear part of the gravity of the transported material during transportation, and this gravity may cause the feed pipe to separate from the discharge pipe. The setting of the auxiliary device solves this technical problem. By twisting the auxiliary screw so that it passes through the arc-shaped clip and abuts the outer wall of the discharge pipe, the connection between the feed pipe and the discharge pipe is strengthened, which can effectively prevent the feed pipe from separating from the discharge pipe.
[0015] Furthermore, a sealing rubber covering the entire surface of the fixing ring is provided on a side of the fixing ring facing the arc-shaped clip.
[0016] By adopting the above technical solution, the sealing rubber can further enhance the sealing performance of the fixed ring after the fixed ring blocks the discharge port of the discharge pipe.
[0017] Furthermore, the sealing rubber is elastic.
[0018] By adopting the above technical solution, the elastic sealing rubber can absorb the vibration impact force generated by the vacuum pump on the fixed ring, reduce the wear of the fixed ring, and will not cause air leakage.
[0019] In summary, this application includes at least one of the following beneficial technical effects:
[0020] 1. By adjusting the setting of the clamp, after the vacuum hopper is installed on the vacuum mixing equipment, when the feed pipe needs to be connected to the discharge pipe of the charging barrel, the inner diameter of the discharge pipe is larger than the outer diameter of the feed pipe. The staff slides the arc-shaped clamp outward and then pushes the feed pipe into the discharge pipe so that the fixed ring blocks the discharge port of the discharge pipe. Then, the arc-shaped clamp is slid to press the outer wall of the discharge pipe. In this way, the feed pipe can be used normally when encountering different diameters of discharge pipes, and the fixed ring blocks the discharge port of the discharge pipe to prevent air leakage, thereby ensuring the transportation efficiency of the vacuum pump in transporting materials, so that the feed pipe can adapt to different diameters of discharge pipes, thereby improving the applicability and practicality of the feed pipe.
[0021] 2. Through the setting of the fixing device, the staff can slide the arc-shaped clip to press the outer wall of the discharge pipe, pick up the fixing bolt to align it with the threaded hole and the connecting hole, and then screw in the fixing bolt so that the fixing bolt passes through the fixing plate and the connecting plate to limit the freedom of the arc-shaped clip and fix it. In this way, the pressure exerted by the arc-shaped clip on the outer wall of the discharge pipe will not disappear because the staff releases their hands, thereby preventing the impact force generated by the airflow during transportation by the vacuum pump from causing the feed pipe to separate from the discharge pipe, making it more convenient for the staff to use the feed pipe.

DETAILED DESCRIPTION
[0025] The present application is further described in detail below with reference to the accompanying drawings.
[0026] Example 1, with reference to Figure 1 、 Figure 2 , a feeding device of a vacuum mixing equipment, comprising a vacuum hopper 1, a vacuum pump and a compressed air backblowing device installed in the vacuum hopper 1, and a feeding pipe 2 connected to the feeding port of the vacuum hopper 1, one end of the feeding pipe 2 is threadedly connected to the vacuum hopper 1, and the other end is provided with an adjusting clamp 3 for making the feeding pipe 2 adapt to the discharge pipes of different apertures of the charging barrel, the adjusting clamp 3 includes a fixed ring 30 fixedly connected to the circumference of the feeding pipe 2 and an arc-shaped clip 31 slidably connected to the fixed ring 30, the feeding pipe 2 passes through the fixed ring 30, and a slide groove 32 is opened on the fixed ring 30, the arc-shaped clip 31 is slidably connected to the fixed ring 30 through the slide groove 32, and there are two arc-shaped clips 31, which are respectively located on both sides of the outside of the feeding pipe 2 and arranged opposite to each other, and the diameter of the fixed ring 30 is larger than the diameter of the feeding pipe 2.
[0027] After the vacuum hopper 1 is installed on the vacuum mixing equipment, when the feed pipe 2 needs to be connected to the discharge pipe of the charging barrel, the inner diameter of the discharge pipe is larger than the outer diameter of the feed pipe 2. The staff slides the arc-shaped clamp 31 outward and then pushes the feed pipe 2 to be inserted into the discharge pipe, so that the fixed ring 30 blocks the discharge port of the discharge pipe, and then slides the arc-shaped clamp 31 to press the outer wall of the discharge pipe. In this way, the feed pipe 2 can be used normally when encountering different diameters of discharge pipes, and by blocking the discharge port of the discharge pipe with the fixed ring 30, air leakage can be prevented, thereby ensuring the transportation efficiency of the vacuum pump in transporting materials, so that the feed pipe 2 can adapt to different diameters of discharge pipes, thereby improving the applicability and practicality of the feed pipe 2.
[0028] The cam 31 is provided with a plurality of screw threads, and the screw thread is fixed on the cam 31, and the cam 31 is provided with a plurality of screw threads, and the screw thread is fixed on the cam 31. 0 and connecting piece 41, after the staff slides the arc clip 31 to press the outer wall of the discharge pipe, pick up the fixing bolt 44 and align it with the threaded hole 42 and the connecting hole 43, and then screw in the fixing bolt 44, so that the fixing bolt 44 passes through the fixing piece 40 and the connecting piece 41 to limit the freedom of the arc clip 31 and fix it. In this way, the pressure applied by the arc clip 31 to the outer wall of the discharge pipe will not disappear when the staff releases their hands, thereby preventing the impact force generated by the airflow during transportation by the vacuum pump from causing the feed pipe 2 to separate from the discharge pipe, making it more convenient for the staff to use the feed pipe 2. A sealing rubber 33 covering the surface of the fixing ring 30 is provided on the side of the fixing ring 30 facing the arc clip 31. The sealing rubber 33 is elastic. After the fixing ring 30 blocks the discharge port of the discharge pipe, the sealing rubber 33 can further enhance the sealing of the fixing ring 30. The elastic sealing rubber 33 can absorb the vibration impact force of the fixing ring 30 due to the vacuum pump extraction, reduce the wear of the fixing ring 30, and will not cause air leakage.
[0029] In Example 2, although the setting of the fixing device 4 can prevent the impact force generated by the airflow during transportation by the vacuum pump from causing the feed pipe 2 to separate from the discharge pipe, the feed pipe 2 needs to bear part of the gravity of the transported material during transportation. This gravity may cause the feed pipe 2 to separate from the discharge pipe. In order to solve this technical problem, in this embodiment, an auxiliary device for preventing the feed pipe 2 from separating from the discharge pipe is provided on the side of the two arc-shaped clips 31 facing away from each other. The auxiliary device includes an auxiliary screw 5 threadedly connected to the arc-shaped clip 31. The auxiliary screw 5 passes through the arc-shaped clip 31 and abuts the outer wall of the discharge pipe. By twisting the auxiliary screw 5, it passes through the arc-shaped clip 31 and abuts the outer wall of the discharge pipe. In this way, the connection between the feed pipe 2 and the discharge pipe is strengthened, which can effectively prevent the feed pipe 2 from separating from the discharge pipe.

[0031] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
