Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, and in particular to a feeding enhancement device. Background Art

[0002] Currently, traditional flat double-sided feeders offer excellent feeding performance and stable output when processing conventional powders, such as calcium powder, which have high density and good fluidity. However, with the continuous advancement of production technology and the increasing variety of materials, traditional feeders have encountered challenges when processing certain special materials, especially low-density, fluffy materials. Due to their low density and large volume, these materials are prone to bridging and blockage during the feeding process, resulting in uneven feeding, low output, and even affecting the stability and efficiency of the entire production line.

[0003] A search revealed a Chinese utility model with authorization publication number CN213472134U, which discloses a side feeding device for lightweight powders. This patent adds a stirring device, including a hopper, paddles, and a driving reduction motor, and utilizes the rotation of the paddles to compact the material and feed it into the feeding barrel, thereby preventing the material from staying on the feeding screw and causing bridging and agglomeration, thereby avoiding human intervention and improving production efficiency. However, for low-density and fluffy materials, although the design of the paddles can improve the compactness of the material to a certain extent, there are still problems due to its own physical properties. The low-density and fluffy material itself may have poor fluidity, resulting in poor fluidity even under the push of the paddles. Utility Model Content

[0042] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0043] Example 1

[0044] like Figure 1-6 As shown, a feeding enhancement device comprises:

[0045] Side feeding box 1;

[0046] The side feeding cylinder 2 is connected to the side feeding box 1, and a feed port 21 and a discharge port 22 are provided on the side feeding cylinder 2. A material channel is provided in the side feeding cylinder 2, and the feed port 21 and the discharge port 22 are both connected to the material channel;

[0047] The side feeding cylinder 2 is provided with an air extraction port 51, which is suitable for connecting the material channel with the outside world;

[0048] A material flow optimization component 5 , which is adapted to cover the air extraction port 51 , and includes a sealing component, a filter component, and an air extraction pipe 52 ;

[0049] The sealing assembly includes an exhaust cover plate 53, an exhaust pipe 52 connected to the exhaust cover plate 53 and communicating with the material channel, and the exhaust pipe 52 is suitable for extracting excess air in the material channel;

[0050] The filter assembly is arranged between the material channel and the air extraction cover plate 53 .

[0051] like Figure 6 As shown, the sealing assembly further includes a PTFE pad 56, which is connected to the bottom of the air extraction cover plate 53;

[0052] The side of the PTFE pad 56 abuts against the inner wall of the air extraction port 51 .

[0053] like Figure 5 As shown, the filter assembly includes a filter plate 55 , which is connected to the bottom of a PTFE pad 56 .

[0054] like Figure 5 As shown, the filter plate 55 is set to a high mesh number.

[0055] like Figure 4As shown, a porous plate 54 is provided at the bottom of the filter plate 55 .

[0056] The working principle of this embodiment is as follows:

[0057] When in use, the original side feeder is connected to the feed port 21 of the feeding enhancement device to transport the material into the material channel, and finally the material is discharged through the discharge port 22;

[0058] When conveying low-density and fluffy materials, in order to further improve the feeding efficiency, a material flow optimization component 5 is set and started in the material channel. After starting, the exhaust pipe 52 starts to work, and the exhaust pipe 52 extracts excess air in the material channel through the exhaust port 51. During this process, the exhaust port 51 is covered and sealed by the exhaust cover 53. At the same time, the polytetrafluoroethylene pad 56 at the bottom of the exhaust cover 53 is abutted against the inner wall of the exhaust port 51. The two are combined to form a double seal to prevent the exhaust pipe 52 from leaking during the exhaust process.

[0059] A high-mesh filter plate 55 is provided at the bottom of the PTFE pad 56 to prevent larger particles from entering the air extraction port 51, ensuring that only air is extracted to prevent the air extraction port 51 from being blocked by material.

[0060] The porous plate 54 provided at the bottom of the filter plate 55 helps to evenly distribute the air extraction effect, ensuring that the air in the entire system is effectively extracted, thereby improving the fluidity of the material;

[0061] The material eventually flows out from the discharge port 22. The above components ensure that the material can still flow smoothly after the air is extracted, and will not be attracted to the air extraction port 51 due to negative pressure. By controlling the negative pressure, the material can maintain stability and continuity during the flow process.

[0062] By reducing the air content between materials, the materials can be more compact, thereby improving feeding stability and efficiency. This is especially true for low-density or fluffy materials, which can effectively prevent feeding difficulties caused by fluffy materials.

[0063] Example 2

[0064] like Figure 2 As shown, this embodiment further includes the following structures based on the first embodiment: it also includes a conveying assembly 6, the conveying assembly 6 includes an auger 61 rotatably installed in the material channel and a driving assembly 3;

[0065] The driving assembly 3 is connected to the auger 1 61 so as to enable the auger 1 61 to rotate in the material channel.

[0066] like Figure 1 As shown, the driving assembly 3 includes a reducer 31 installed on one side of the side feeding box 1, and the output shaft of the reducer 31 is connected to the rotating shaft of the auger 61.

[0067] like Figure 2 As shown, the conveying assembly 6 also includes an auger 2 62 and a rotating assembly;

[0068] The second auger 62 is rotatably installed in the material channel, and the second auger 62 and the first auger 61 are arranged side by side;

[0069] The rotating assembly is connected to the second auger 62 and the first auger 61 respectively so as to drive the first auger 61 and the second auger 62 to rotate in opposite directions.

[0070] like Figure 2 As shown, the rotating assembly includes a gear 1 32 fixedly mounted on the shaft of the auger 1 61 and a gear 2 33 fixedly mounted on the shaft of the auger 2 62;

[0071] Auger 1 61 and auger 2 62 are meshed with each other.

[0072] like Figure 1 As shown, an adjustment component 4 is provided on the side feeding box body 1, and the adjustment component 4 includes a fixed hinge seat 41, a hinge plate 1 42, a hinge plate 2 43 and a connecting shaft 44 which are movably hinged through a hinge shaft, and the connecting shaft 44 is connected to the side feeding box body 1.

[0073] The working principle of this embodiment is as follows:

[0074] While the material flow optimization component 5 improves the feeding efficiency by means of vacuum negative pressure, it is also provided with two auger 1 61 and auger 2 62 that rotate in opposite directions, and the feeding speed is further increased by the auger 1 61 and auger 2 62 rotating in opposite directions;

[0075] First, start the reducer 31. The output shaft of the reducer 31 and the shaft of the auger 1 61 drive the auger 1 61 to rotate. When the auger 1 61 rotates, the gear 1 32 sleeved on the outside of its shaft rotates synchronously and engages with the gear 2 33 outside the shaft of the auger 2 62, thereby driving the rotation of the auger 2 62, so as to realize the work of the auger 1 61 and the auger 2 62 rotating in opposite directions to transport materials.

[0076] In addition, the reinforcing device needs to be docked with the original side feeder. In order to make the docking more flexible according to the actual working environment, an adjustment component 4 is provided. The connecting shaft 44 in the adjustment component 4 is directly docked with the reinforcing device body, and the fixed hinge seat 41 is docked with a fixed base. The two are movably hinged by a hinge plate 1 42 and a hinge plate 2 43 through the hinge shaft to realize multiple movable points. One end of the hinge plate 1 42 is movably hinged to the fixed hinge seat 41, and the other end of the hinge plate 1 42 is movably hinged to one end of the hinge plate 2 43. The other end of the hinge plate 2 43 is movably hinged to the connecting shaft 44.

[0077] During installation, after fixing the fixed hinge seat 41, the position of the reinforcement device body is adjusted according to the actual situation by coordinating multiple movable points, so that it is connected to the original side feeder and fixed through the fixing assembly, which can be bolts and nuts.

[0078] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
