Description

Technical Field

[0001] This utility model relates to the field of foamed microsphere feeding technology, and in particular to an anti-clogging feeding device for foamed microspheres. Background Technology

[0002] As a novel functional material, foamed microspheres have shown broad application prospects in fields such as construction, packaging, and biomedicine. As a key piece of equipment in the production process of foamed microspheres, the rationality of the structure of the sealing and feeding device directly affects product quality and production efficiency. For example, patent application number (CN217395515U) discloses a feeding device for foamed microspheres. By using an intermittent rotation mechanism, the intermittent feeding of foamed microspheres can be achieved, which effectively prevents the material from entering the processing equipment all at once and resulting in poor processing effect. At the same time, the amount of material falling at each through-hole can be adjusted by setting a sliding column, baffle plate, connecting block and hand screw, so that the feeding range is wide. Secondly, by using a reciprocating striking mechanism, two striking balls can intermittently strike the outside of the feeding pipe, which effectively prevents the material from blocking the feeding pipe and greatly improves the feeding efficiency. Its design is reasonable, but there are still some shortcomings in the structural design. Existing technologies attempt to loosen clogged foamed microspheres and allow them to continue flowing by periodically tapping the conveying pipe. However, this method has significant drawbacks. First, the force and frequency of tapping are difficult to control precisely; tapping too lightly will not effectively solve the clogging problem, while tapping too heavily may damage the conveying pipe. Second, the tapping process generates considerable noise, which interferes with the working environment. Furthermore, existing feeding devices are often not designed to provide uniform feeding of foamed microspheres, which can easily lead to clogging of the conveying pipe. Utility Model Content

[0003] The anti-clogging feeding device for foamed microspheres proposed in this utility model solves the problems of poor effect and high noise of the existing anti-clogging feeding device for foamed microspheres by tapping, as well as the problem of clogging caused by uneven feeding.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A clog-resistant feeding device for foamed microspheres includes a feeding hopper, a support frame bolted to the middle of the feeding hopper, a stirring mechanism located inside the feeding hopper below the support frame, a conveying pipe welded to the bottom of the feeding hopper, an annular adjusting groove opened inside the upper part of the conveying pipe, a matching baffle plate inside the annular adjusting groove, and a through-hole adapted to the diameter of the conveying pipe inside the baffle plate. An anti-clogging mechanism is installed inside the conveying pipe. The anti-clogging mechanism includes an annular air supply pipe and jet nozzles. The annular air supply pipe is fixedly installed inside the material supply pipe below the baffle plate. Multiple sets of jet nozzles are arranged inside the lower part of the annular air supply pipe, and the jet nozzles impact the clogged foamed microspheres.

[0005] Preferably, an mounting plate is fixedly connected to the outside of the feed hopper, and the mounting plate has multiple sets of fixing holes inside.

[0006] Preferably, the stirring mechanism includes a stirring motor, a stirring shaft, and spiral stirring blades, and the stirring motor is fixedly installed inside the support frame, the output end of the stirring motor is fixedly connected to the stirring shaft, and the spiral stirring blades are connected to the outside of the stirring shaft.

[0007] Preferably, an installation groove is provided below the annular adjusting groove at the side end of the conveying pipe, and a drive motor is fixedly installed inside the installation groove, with the output end of the drive motor connected to the baffle plate.

[0008] Preferably, the baffle plate has an arc-shaped limiting groove inside, and the top of the annular adjusting groove is fixedly connected with a limiting rod that matches the arc-shaped limiting groove.

[0009] Preferably, the anti-clogging mechanism further includes a fixing plate, connecting holes, an air compressor, and a connecting pipe, and the fixing plate is connected to the outside of the material conveying pipe, and the fixing plate is provided with multiple sets of connecting holes inside.

[0010] Preferably, an air compressor is fixedly installed on the top of the fixed plate on both sides of the conveying pipe, and the top of the air compressor is connected to the annular air conveying pipe inside the conveying pipe through a connecting pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The anti-clogging feeding device for the foamed microspheres has an anti-clogging mechanism inside the conveying pipe. It uses high-pressure air from an air compressor to prevent clogging. An annular air supply pipe and an air nozzle are installed on the conveying pipe. High-pressure air is introduced into the air nozzle through the air compressor to impact the foamed microspheres that are blocked inside the conveying pipe, loosening them and allowing them to continue flowing. Compared with knocking to prevent clogging, high-pressure air can act evenly on the blocked area, effectively solving the clogging problem. In addition, the high-pressure air anti-clogging method has low noise and will not interfere with the working environment.

[0012] 2. The annular regulating trough is equipped with a matching baffle plate, and the baffle plate has a through-hole. When the baffle plate rotates to open the conveying pipe, the foamed microspheres will fall into the conveying pipe through the through-hole. Then, the baffle plate rotates to close the conveying pipe. Thus, as the baffle plate rotates, the foamed microspheres enter the conveying pipe intermittently, thereby adjusting the feed rate of the foamed microspheres, achieving uniform feeding, and preventing blockage. Secondly, a stirring mechanism is set inside the feed hopper below the support frame. The rotating spiral stirring blades can effectively prevent the foamed microspheres from accumulating and interrupting the flow in the feed hopper, improving the smoothness of feeding.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1 Reference Figures 1-4 The anti-clogging feeding device for foamed microspheres includes a feeding hopper 1. A support frame 3 is installed in the middle of the feeding hopper 1 by bolts 2. A stirring mechanism is set inside the feeding hopper 1 below the support frame 3. A conveying pipe 4 is welded to the bottom of the feeding hopper 1. An annular adjusting groove 6 is opened inside the upper part of the conveying pipe 4. A matching baffle plate 7 is set inside the annular adjusting groove 6. A through port 8 that matches the diameter of the conveying pipe 4 is set inside the baffle plate 7.

[0020] Reference Figure 1 , Figure 2 The stirring mechanism includes a stirring motor 13, a stirring shaft 14, and a spiral stirring blade 15. The stirring motor 13 is fixedly installed inside the support frame 3. The stirring motor 13 can be of type JB90-D. The output end of the stirring motor 13 is fixedly connected to the stirring shaft 14, and the spiral stirring blade 15 is connected to the outside of the stirring shaft 14.

[0021] Reference Figure 3 , Figure 4 Below the annular adjusting groove 6, an installation groove 16 is provided on the side end of the conveying pipe 4, and a drive motor 17 is fixedly installed inside the installation groove 16. The output end of the drive motor 17 is connected to the baffle plate 7. An arc-shaped limiting groove 18 is provided inside the baffle plate 7, and a limiting rod 19 adapted to the arc-shaped limiting groove 18 is fixedly connected to the top of the annular adjusting groove 6. An installation plate 11 is fixedly connected to the outside of the feed hopper 1, and multiple sets of fixing holes 12 are provided inside the installation plate 11.

[0022] In practical implementation, the anti-clogging feeding device for foamed microspheres is used by first installing the feeding device on the machine tool through the mounting plate 11, the fixing plate 20, and the fixing holes 12 and connecting holes 21 inside. Then, the foamed microspheres are poured into the feed hopper 1, and the stirring motor 13 is started. The stirring motor 13 drives the stirring shaft 14 and the outer spiral stirring blades 15 to rotate and stir inside the feed hopper 1, which can effectively prevent the accumulation and flow interruption of the foamed microspheres in the feed hopper 1. Then, the drive motor 17 is started, and the drive motor 17 drives the material stop. The baffle plate 7 rotates inside the annular adjustment groove 6. When it is necessary to open the conveying pipe 4 for feeding, the drive motor 17 drives the baffle plate 7 to rotate. Because the baffle plate 7 has an arc-shaped limiting groove 18 inside, and the top of the annular adjustment groove 6 is fixedly connected with a limiting rod 19 that matches the arc-shaped limiting groove 18, the rotating baffle plate 7 can rotate along the outside of the limiting rod 19 through the arc-shaped limiting groove 18, so that the through-hole 8 inside the baffle plate 7 is aligned with the conveying pipe 4, thereby enabling the foamed microspheres inside the feed hopper 1 to enter the conveying pipe 4 through the through-hole 8. In addition, when it is necessary to close the conveying pipe 4, the drive motor 17 drives the baffle plate 7 to rotate in the opposite direction. Under the limit of the limit rod 19, the conveying pipe 4 is blocked. Through the above operation, the foamed microspheres are intermittently allowed to enter the conveying pipe 4, thereby adjusting the feed rate of the foamed microspheres, preventing blockage, and greatly improving the feeding efficiency.

[0023] Example 2 Reference Figure 2This embodiment is an optimization based on embodiment one. An anti-clogging mechanism is provided inside the material conveying pipe 4. The anti-clogging mechanism includes an annular air conveying pipe 9 and a jet nozzle 10. The annular air conveying pipe 9 is fixedly installed inside the material conveying pipe 4 below the baffle plate 7. Multiple sets of jet nozzles 10 are provided inside the lower part of the annular air conveying pipe 9. The jet nozzles 10 impact the clogged foamed microspheres. The anti-clogging mechanism also includes a fixing plate 20, a connecting hole 21, an air compressor 22, and a connecting pipe 23. The fixing plate 20 is connected to the outside of the material conveying pipe 4. Multiple sets of connecting holes 21 are provided inside the fixing plate 20. An air compressor 22 is fixedly installed on the top of the fixing plate 20 on both sides of the material conveying pipe 4. The air compressor 22 can be of type SA55-200. The top of the air compressor 22 is connected to the annular air conveying pipe 9 inside the material conveying pipe 4 through the connecting pipe 23.

[0024] In practical implementation, when the conveying pipe 4 is blocked, the anti-clogging feeding device for foamed microspheres first starts the air compressor 22. The air compressor 22 delivers high-pressure air to the inside of the conveying pipe 4 through the connection hole 21. Then, multiple sets of air jets 10 impact the foamed microspheres blocked inside the conveying pipe 4. Under the impetus of the high-pressure air, the blockage of the conveying pipe 4 can be effectively prevented, and the smoothness of feeding can be improved. In this way, through the above operation, the high-pressure air anti-clogging method of the air compressor 22 can evenly act on the blocked part, effectively solving the blockage problem. At the same time, it will not interfere with the working environment and has low noise.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
