Description

Technical Field

[0001] The utility model relates to the technical field of vacuum feeding, in particular to a vacuum feeding device which is convenient for powder processing. Background Art

[0002] The vacuum feeder is a dust-free and closed pipeline conveying equipment that uses vacuum suction to convey granular materials. It uses the pressure difference between the vacuum and the ambient space to form gas flow in the pipeline, drive the movement of powdered materials, and thus complete the material transportation, which greatly reduces the labor intensity of workers. Therefore, it has been favored by many industrial equipment manufacturers.

[0003] The Chinese patent authorization announcement number CN212608116U discloses a new type of vacuum feeder suction device, including a vacuum feeder main body, a suction pipe fixedly connected to one side of the vacuum feeder main body, a suction hopper fixedly connected to the side of the suction pipe away from the vacuum feeder main body, and a retaining ring fixedly connected to the inner wall of the suction hopper; the utility model arranges a protective pad, a slider and a slide groove. The arrangement of the protective pad prevents the cam from directly hitting the arc filter screen and avoids damage to the arc filter screen. The arrangement of the slider and the slide groove facilitates better driving the vertical shaking of the fixed ring and avoids the lateral shaking of the fixed ring. The device is simple to operate and has better use effect, greatly improves the suction speed of the device, and prevents large pieces of material from entering the interior of the vacuum feeder main body.

[0004] By reviewing the above comparative documents, it can be seen that the prior art still has the following deficiencies. Since a filter is installed in the suction hopper to filter large pieces of material, the large pieces of material are shaken down by hitting the filter. However, after the large pieces of material fall down, they will still be repeatedly adsorbed to the filter by suction. After a long time, the filter is still easily blocked by large pieces of material, and even affects the efficiency of the filter in filtering powder. The feeding efficiency will also be affected. Moreover, when the opening of the suction hopper is facing upward for feeding, when the large pieces of material are cleaned by knocking on the filter, the large pieces of material will still fall on the filter and are difficult to clean or utilize. Therefore, how to quickly and effectively process and utilize large pieces of material still needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0027] like Figure 1-5As shown, in this embodiment, it includes a feeding body 1 and a vacuum pump 2, the vacuum pump 2 is installed outside the feeding body 1, the feeding port of the feeding body 1 is connected with a feeding pipe 3, the end of the feeding pipe 3 is connected with a suction hopper 4, a fixed frame 5 is fixed in the suction hopper 4, a filter plate 6 is fixed in the fixed frame 5, a sliding block 8 is provided below the filter plate 6, a lower ventilation plate 12 is fixed at the lower end of the sliding block 8, two grinding rollers 14 are provided at the lower end of the lower ventilation plate 12, a sliding drive assembly is provided at the lower end of the filter plate 6, and the sliding drive assembly includes a forward and reverse motor 7, a screw rod 20 and a guide shaft 21, the forward and reverse motor 7 is fixed to the right end of the suction hopper 4, one end of the screw rod 20 is connected to the power end of the forward and reverse motor 7, the other end of the screw rod 20 rotates to the left and penetrates into the suction hopper 4, the sliding block 8 is threadedly sleeved on the outer periphery of the screw rod 20, the guide shaft 21 is fixed in the suction hopper 4, the sliding block 8 is slidably sleeved on the guide shaft 21, the front and rear parts of the lower end of the lower ventilation plate 12 are fixed with fixed plates 13, one end of the grinding roller 14 is rotatably connected to one of the fixed plates 13, and two driving motors 15 are fixed on the inner side of the other fixed plate 13, and the other ends of the two grinding rollers 14 are connected to the power ends of the two driving motors 15 one by one.

[0028] When the powder material is fed through the vacuum feeding device, the vacuum pump 2 works, and then the powder material is adsorbed through the suction hopper 4. At the same time, the forward and reverse motors 7 drive the screw rod 20 to rotate back and forth, and the screw rod 20 drives the sliding block 8 to move back and forth along the guide shaft 21, and the drive motor 15 is started to drive the grinding roller 14 to rotate, that is, the two grinding rollers 14 rotate inward. Therefore, when large pieces of material enter the suction hopper 4, the suction force will enter between the two grinding rollers 14 through the upper ventilation plate 11 and the lower ventilation plate 12. Since there is suction between the two grinding rollers 14, the suction force will adsorb part of the large pieces of material between the two grinding rollers 14, and then the two grinding rollers 14 will grind part of the large pieces of material into powder in advance, which is beneficial to reduce the situation where large pieces of material are adsorbed on the filter plate 6, so that the filter plate 6 has better filtering and feeding performance for powder.

[0029] like Figure 2 , 4 As shown, in this embodiment, an upper ventilation plate 11 is fixed to the upper end of the sliding block 8, a rolling roller 9 is rotatably connected to the middle of the upper end of the upper ventilation plate 11, brush rollers 10 are fixed on both sides of the upper end of the upper ventilation plate 11, and a discharge valve 19 is connected to the discharge port of the feeding machine body 1.

[0030] When another part of the bulk material is adsorbed onto the surface of the filter plate 6, the bristles on the brush roller 10 are set to contact the surface of the filter plate 6. As the sliding block 8 moves back and forth, it will drive the upper ventilation plate 11, the brush roller 10 and the rolling roller 9 to move back and forth together. Then, the brush roller 10 sweeps the filter plate 6 back and forth, which is conducive to cleaning the powder material blocked in the mesh of the filter plate 6. In addition, the rolling roller 9 rolls back and forth the cleaned materials and another part of the bulk material, which is conducive to further rolling the materials. into powder until it can be filtered through the filter plate 6 and adsorbed into the feeding body 1, thereby obtaining qualified powder material, which can better prevent the material from clogging the filter plate 6, and finally the powder processed by the feeding body 1 is discharged through the discharge valve 19. In summary, compared with the prior art, in this technical solution, no matter whether the material port of the suction hopper 4 is facing downward or upward to feed the material, it will not cause the problem of large pieces of material being unable to be processed and difficult to utilize, and it is conducive to quickly and effectively processing and utilizing large pieces of material.

[0031] like Figure 2 As shown, in this embodiment, the front-to-back lengths of the brush roller 10 and the rolling roller 9 are consistent with the front-to-back length of the filter plate 6.

[0032] Since the front-to-back lengths of the brush roller 10 and the rolling roller 9 are consistent with the front-to-back length of the filter plate 6, it is beneficial to use the brush roller 10 to clean the filter plate 6 more comprehensively, and it is beneficial to use the rolling roller 9 to grind large pieces of material on the filter plate more comprehensively.

[0033] like Figure 1 As shown, in this embodiment, a brake motor 16 is fixed on the right side of the feeding body 1, a main gear 17 is connected to the power end of the brake motor 16, a sub gear 18 is fixedly sleeved on the outer periphery of the feeding tube 3, and the main gear 17 is meshed with the sub gear 18.

[0034] When it is necessary to adjust the suction position of the suction hopper 4, the main gear 17, the sub-gear 18, the feeding pipe 3 and the suction hopper 4 are driven to rotate together through the operation of the brake motor 16, so that the suction position of the suction hopper 4 can be conveniently adjusted. When the material port of the suction hopper 4 is downward, it is conducive to adsorbing the material below it. When the material port of the suction hopper 4 is upward, materials are added to the suction hopper 4, and materials can also be fed into the feeding body 1 through the suction force of the vacuum pump 2, which effectively improves practicality.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementation schemes of the present invention. In addition, other implementation schemes are also included. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
