Description

Technical Field

[0001] This utility model relates to the technical field of extruder accessories, and in particular to an anti-clogging feeding device for an extruder. Background Technology

[0002] The production of rice crackers using an extruder primarily employs extrusion puffing technology. During the extrusion puffing process, the starch gelatinizes and the protein denatures under the high temperature and high pressure environment of the extruder. When the material is extruded from the extruder outlet, the pressure drops instantly, and the moisture evaporates rapidly, causing the material to expand and form a loose, porous structure. Rice crackers produced using this process have a crispy texture, and their shape, density, and texture can be controlled by adjusting the parameters of the extruder (such as temperature, pressure, and screw speed).

[0003] The prior art, with publication number CN221469004U, discloses a discharge device for an extruder, including an extruder body. A feed hopper is fixedly connected to the top of the extruder body, and a discharge box is provided at one end of the extruder body. A connecting plate is fixedly connected to the outer surface of the discharge box, and bolts are threadedly connected to the inside of the connecting plate.

[0004] During operation, the rice raw material is conveyed by a spiral feeding roller. During this process, the spiral feeding roller continuously rubs against the rice grains. As usage time increases, the surface of the spiral feeding roller gradually wears down. This wear can lead to reduced conveying efficiency because the gap between the roller and the pipe wall may increase due to wear, allowing rice to flow back or accumulate in the gap during transport. During transport, some broken rice, rice flour, or impurities may adhere to the spiral feeding roller. If not cleaned for a long time, these deposits can breed bacteria and mold, especially in humid environments. Furthermore, the spiral feeding roller is not easily disassembled, making subsequent maintenance difficult. Additionally, the feed end is not easily protected when not in use, allowing dust and other impurities to easily enter and affect subsequent operation. Therefore, an anti-clogging feeding device for the extruder is needed to solve these problems.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0034] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an anti-clogging feeding device for an extruder, comprising:

[0035] The puffing body 1 is described in detail here. It should be noted that the specific structure of the puffing body 1 is existing technology and will not be elaborated here.

[0036] A feeding hopper 2 is fixedly installed on the extruder body 1. An anti-blocking mechanism is installed on the feeding hopper 2. It should be noted that the anti-blocking mechanism can prevent clogging during feeding and facilitate the removal of the spiral feeding roller 8 for maintenance and cleaning, ensuring the feeding effect. At the same time, when not in use, the feeding hole 17 can be sealed to prevent dust and other impurities from entering.

[0037] The anti-clogging mechanism includes an electric telescopic rod 3, a push plate 4, a ring 5, a round cover 6, a power motor 7, a spiral feeding roller 8, a splicing block 9, and a positioning block 11;

[0038] The electric telescopic rod 3 is fixedly installed on the feed hopper 2. The telescopic end of the electric telescopic rod 3 is fixedly connected to the push plate 4. The push plate 4 is fixedly connected to the ring 5. The power motor 7 is fixedly installed on the round cover 6. The output end of the power motor 7 is fixedly connected to the spiral feed roller 8. It should be noted that starting the power motor 7 can make the spiral feed roller 8 rotate. The spiral feed roller 8 can convey materials and avoid blockage.

[0039] The splicing block 9 is slidably installed on the push plate 4 and the ring 5. The splicing block 9 is engaged with the round cover 6. The positioning block 11 is fixedly installed on the feed hopper 2. The positioning block 11 is engaged with the splicing block 9.

[0040] With the aforementioned anti-clogging mechanism, when maintenance and cleaning of the spiral feed roller 8 are required, the electric telescopic rod 3 is activated until the positioning block 11 is moved out of the splicing block 9. Then, the splicing block 9 is pulled to release the limit on the round cover 6. Next, the rotating shaft 13 is pulled upward to pull the round cover 6 upward, thereby allowing the spiral feed roller 8 to be removed. This makes it convenient to maintain and clean the spiral feed roller 8.

[0041] Specifically, the anti-clogging mechanism also includes a block 12, a rotating shaft 13, a connecting rod 15, and a protective cover 16. The block 12 is fixedly installed inside the feed hopper 2, the rotating shaft 13 is rotatably installed on the round cover 6, the block 12 is engaged with the rotating shaft 13, the connecting rod 15 is fixedly connected to the rotating shaft 13 and the protective cover 16, the top of the round cover 6 has a feeding hole 17, the protective cover 16 covers the feeding hole 17, and the bottom end of the protective cover 16 is in contact with the round cover 6.

[0042] With the aforementioned anti-clogging mechanism, when not in use, the rotating shaft 13 is rotated so that the protective cover 16 covers the feeding hole 17. Then, the electric telescopic rod 3 is activated so that the round cover 6 moves down until the square block 12 is inserted into the square groove 14, which limits the rotating shaft 13 and can seal the feeding hole 17 to prevent dust and other impurities from entering.

[0043] Specifically, the round cover 6 has a splicing groove 10, and the splicing block 9 is engaged with the splicing groove 10. The splicing block 9 has a T-shaped structure and contacts the side of the push plate 4. It should be noted that the round cover 6 can be limited.

[0046] Specifically, the top of the splicing block 9 is provided with a positioning hole, and the positioning block 11 is engaged with the positioning hole. It should be noted that the splicing block 9 can be limited. The height of the square groove 14 is less than the height of the positioning hole. When the square block 12 moves out of the square groove 14, the positioning block 11 is still partially located in the positioning hole.

[0047] Working principle:

[0048] S1: Starting the power motor 7 will cause the screw feed roller 8 to rotate, which will convey the material and prevent blockage.

[0049] S2: When maintenance and cleaning of the spiral feed roller 8 are required, start the electric telescopic rod 3, which will cause the push plate 4 to move the ring 5 upward, and the ring 5 to move the round cover 6 upward until the positioning block 11 is moved out of the splicing block 9. Then pull the splicing block 9 to release the limit on the round cover 6. Then pull the rotating shaft 13 upward to pull the round cover 6 upward, and then the spiral feed roller 8 can be taken out, which makes it convenient to maintain and clean the spiral feed roller 8.

[0050] S3: When not in use, rotate the shaft 13 so that the protective cover 16 covers the feeding hole 17. Then, activate the electric telescopic rod 3 to move the round cover 6 down until the block 12 is inserted into the square groove 14, which limits the rotation shaft 13 and seals the feeding hole 17 to prevent dust and other impurities from entering. When in use, activate the electric telescopic rod 3 to release the limit on the shaft 13. Then, rotate the shaft 13 to expose the feeding hole 17. Finally, activate the electric telescopic rod 3 to reset the round cover 6.
