Description

Technical Field

[0001] This utility model relates to the field of powder filling technology, specifically to a powder filling feeding anti-blocking device. Background Technology

[0002] Powder filling is a technology that accurately fills solid powder materials into containers. This technology controls the filling mechanism in the filling equipment to accurately fill the powder material in a predetermined quantity, and it has a wide range of applications.

[0003] In the existing powder filling process, material blockage is a common problem. To solve this problem, an auger (screw feeder) is usually added to the hopper to enhance the flowability of the powder material. However, powdery materials are very easy to be adsorbed on the inner wall of the hopper. The adsorbed powder will gradually accumulate, reducing the effective flow area of ​​the hopper and forming bridging or rat hole phenomena, which will exacerbate the risk of blockage. Secondly, the powder adsorbed on the inner wall may form stubborn clumps, which will cause material contamination or inaccurate filling metering after falling off. Utility Model Content

[0004] The purpose of this utility model is to provide a powder filling and feeding anti-clogging device to solve the problem that powdery materials are easily adsorbed on the inner wall of the hopper, and the attached powder will gradually accumulate, reducing the effective flow area of ​​the hopper and forming bridging or rat hole phenomena, which will aggravate the risk of clogging.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a powder filling and feeding anti-clogging device, including a hopper. Two sets of anti-clogging structures are symmetrically installed on the outer side of the hopper. Each anti-clogging structure includes a striking block that contacts the outer wall of the hopper. A driving component is provided on the outer side of the hopper, and the driving component is connected to the two sets of anti-clogging structures in a transmission manner.

[0006] Furthermore, the anti-blocking structure also includes an arc-shaped plate installed on the outside of the hopper. A horizontal plate is provided on the outside of the arc-shaped plate, and a T-shaped vertical plate is installed on the upper end of the horizontal plate. The side plate is connected to the outside of the T-shaped vertical plate through a reset assembly. The striking block is installed on the outside of the side plate. Two limiting rings are provided on the outside of the discharge pipe of the hopper. The arc-shaped plates of the two sets of the anti-blocking structure are installed between the two limiting rings and fixed with bolts.

[0007] Furthermore, a connecting plate is also installed on the outer side of the T-shaped vertical plate, one end of the connecting plate is provided with a sliding groove, and a slider is fixedly installed at the lower end of the side plate, the slider being slidably connected to the sliding groove.

[0008] Furthermore, the lower end of the connecting plate is provided with a support plate, and the other end of the support plate is fixed to the upper end of the horizontal plate.

[0009] Furthermore, a guide rod is also installed on the outer side of the side plate, with one end of the guide rod penetrating through the T-shaped vertical plate.

[0010] Furthermore, the reset assembly includes a sleeve fixedly installed on the outside of the T-shaped vertical plate. A cover plate is installed at one end of the sleeve, and a sliding plate is slidably connected inside the sleeve. A sliding rod is connected to one end of the sliding plate, and one end of the sliding rod passes through the cover plate and is fixedly connected to the outside of the side plate. A spring is disposed inside the sleeve, with one end connected to the inner wall of the sleeve and the other end connected to the sliding plate.

[0011] Furthermore, the drive assembly includes a rotating shaft, which is rotatably connected to the outside of the hopper via two support frames. A toggle block is fixedly installed in the middle of the rotating shaft, and a half-tooth gear is fixedly installed on the rotating shaft. Racks are installed on the side plates of both sets of anti-blocking structures, and the two racks are symmetrically arranged vertically and mesh with the half-tooth gear.

[0012] Furthermore, a timing pulley is fixedly installed at one end of the rotating shaft.

[0013] This utility model has the following beneficial effects: (1) This utility model sets two anti-blocking structures driven by a single driving source, which alternately generate periodic mechanical impacts on the outer wall of the hopper. The impact force is effectively transmitted to the inner wall of the hopper, shaking off the adsorbed powder and directly destroying the existing bridging and rat hole structures, thereby solving the problem of reduced flow area and increased blockage risk caused by powder adhesion and accumulation.

[0014] (2) The agitator plate of this utility model is fixedly installed in the middle of the rotating shaft and makes synchronous circular motion with the continuous rotation of the rotating shaft. Its motion trajectory makes it repeatedly cut into and pass through the powdery material layer inside the hopper. The rotational motion of the agitator plate enables it to continuously stir, turn and crush the powdery material inside the hopper, break the static balance that may be formed inside the material, and effectively prevent bridging and rat hole phenomena caused by the static placement of the material.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-4 As shown, this embodiment discloses an implementation method for preventing blockage through driving and tapping: This utility model is a powder filling and feeding anti-blocking device, including a hopper 1, two sets of anti-blocking structures 2 are symmetrically installed on the outside of the hopper 1, and a driving component 3 is provided on the outside of the hopper 1. The driving component 3 is connected to the two sets of anti-blocking structures 2 in a transmission manner. The drive assembly 3 includes a rotating shaft 301, which is rotatably connected to the outside of the hopper 1 via two support frames 302. A toggle block 303 is fixedly installed in the middle of the rotating shaft 301. A half-tooth gear 304 is fixedly installed on the rotating shaft 301. A synchronous wheel 305 is also fixedly installed at one end of the rotating shaft 301. A rack 206 is installed on the side plates 205 of the two sets of anti-blocking structures 2. The two racks 206 are symmetrically arranged and mesh with the half-tooth gear 304. Among them, the synchronous wheel 305 driven by the external motor drives the rotating shaft 301 to rotate continuously, and the half-tooth gear 304 on the rotating shaft 301 rotates accordingly. Its half-tooth structure alternately meshes with the upper and lower racks 206, thereby converting the continuous rotational motion into the alternating, reciprocating linear motion of the two sets of anti-blocking structures 2, realizing the linkage of two sides driven by a single power source. Specifically, the external drive source drives the synchronous pulley 305 to rotate via a belt. The synchronous pulley 305 drives the rotating shaft 301 and its half-tooth gear 304 and actuating block 303 to rotate together. When the toothed part of the half-tooth gear 304 meshes with the upper rack 206, it pushes the anti-blocking structure 2 on that side to move towards the hopper 1 and compresses its reset component 4. At the same time, its toothless part disengages from the lower rack 206. The lower anti-blocking structure 2 moves in the opposite direction under the elastic action of its reset component 4. As the rotating shaft 301 continues to rotate, the half-tooth gear 304 switches to mesh with the lower rack 206, pushing the lower structure forward. At the same time, the upper structure returns to its original position under the elastic action. This cycle is repeated to achieve alternating high-frequency striking of the outside of the hopper 1 by the two sets of striking blocks 201.

[0020] like Figure 5 As shown, this embodiment discloses the implementation method of the anti-blocking structure 2 and the reset guide: The anti-blocking structure 2 includes an arc-shaped plate 202 installed on the outside of the hopper 1. The arc-shaped plate 202 is fixed between two limiting rings 101 on the outside of the discharge pipe of the hopper 1 by bolts. A horizontal plate 203 is provided on the outside of the arc-shaped plate 202. A T-shaped vertical plate 204 is installed on the upper end of the horizontal plate 203. The side plate 205 is connected to the outside of the T-shaped vertical plate 204 through the reset assembly 4. The striking block 201 is installed on the outside of the side plate 205 and contacts the outer wall of the hopper 1. The reset assembly 4 includes a sleeve 401 fixedly installed on the outside of the T-shaped vertical plate 204. A cover plate 402 is installed on one end of the sleeve 401. A slide plate 403 is slidably connected inside the sleeve 401. A slide rod 404 is connected to one end of the slide plate 403. One end of the slide rod 404 passes through the cover plate 402 and is fixedly connected to the outside of the side plate 205. A spring 405 is disposed inside the sleeve 401. One end of the spring is connected to the inner wall of the sleeve 401, and the other end is connected to the slide plate 403. When the rack 206 is pushed by the half-tooth gear 304, the side plate 205 drives the slide bar 404 to move and compress the spring 405, converting kinetic energy into elastic potential energy. When the rack 206 disengages from the half-tooth gear 304, the compressed spring 405 releases its potential energy, pushing the slide plate 403 to reset. Then, the slide bar 404 pulls the side plate 205 and the striking block 201 back to their original positions quickly, preparing for the next strike, thus ensuring the automatic reset and continuous operation of the striking action. A connecting plate 207 is also installed on the outside of the T-shaped vertical plate 204. A groove is provided at one end of the connecting plate 207. A slider 208 is fixedly installed at the lower end of the side plate 205. The slider 208 is slidably connected to the groove. A support plate 209 is provided at the lower end of the connecting plate 207. The other end of the support plate 209 is fixed to the upper end of the horizontal plate 203. A guide rod 5 is also installed on the outside of the side plate 205. One end of the guide rod 5 passes through the T-shaped vertical plate 204. The combination of slider 208 and groove, and guide rod 5 and T-shaped vertical plate 204, together form a stable composite guide mechanism. This ensures that the side plate 205 and its rack 206 and striking block 201 can only reciprocate along a strict straight trajectory, preventing lateral deviation and jamming, and ensuring the accuracy of meshing with the half-tooth gear 304 and the effectiveness of striking force transmission.
