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

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 3 As shown, the present invention provides an apparatus for making chili powder, including a horizontally arranged outer cylinder 1, a sieve cylinder 5 coaxially arranged inside the outer cylinder 1, a crushing mechanism arranged inside the sieve cylinder 5, the crushing mechanism including a rotating shaft 12, a drive assembly connected to the rotating shaft 12, the rotating shaft 12 being coaxially arranged with the sieve cylinder 5, a plurality of telescopic frames arranged circumferentially on the rotating shaft 12, a set of crushing blades arranged on the telescopic frames, and a linkage assembly arranged on the rotating shaft 12. The linkage assembly is used to control the extension and retraction of the telescopic frames along the radial direction of the rotating shaft 12, so as to adjust the distance between the set of crushing blades and the inner wall of the sieve cylinder 5.

[0021] In this embodiment, the drive assembly includes a second motor 24, the output end of which is connected to a drive pulley. One end of the rotating shaft 12 is fixedly fitted with a driven pulley 19, and the shaft is driven by a belt. A feed hopper 8 is connected to the upper part of the outer cylinder 1 to facilitate the feeding of dried chili raw materials into the sieve cylinder 5.

[0022] The second motor 24 drives the rotating shaft 12 to rotate, which in turn rotates the crushing blade assembly on the telescopic frame, thus crushing the dried chili raw materials. The linkage component controls the radial extension and retraction of the telescopic frame along the rotating shaft 12, thereby adjusting the distance between the crushing blade assembly and the inner wall of the sieve cylinder 5. This design allows the device to adapt to dried chili raw materials of different sizes, hardnesses, and initial states. Whether the chilies are large and hard, or relatively fine and soft varieties, the ideal crushing effect can be achieved by adjusting the position of the crushing blade assembly, improving the flexibility and versatility of the crushing process.

[0023] Furthermore, the telescopic frame includes two sliding seats fixedly sleeved on the rotating shaft 12. Multiple sliding rods 10 are slidably connected at equal intervals along the circumference of the rotating shaft 12 on any sliding seat. The sliding rods 10 on the two sliding seats are correspondingly arranged, and a tool holder 3 is connected between the relatively arranged sliding rods 10. The middle part of the tool holder 3 is connected to the linkage component.

[0024] The telescopic frame's structural design allows the crushing blade assembly to extend and retract radially along the rotating shaft 12 under the action of the linkage component, thereby changing the distance between the crushing blade assembly and the inner wall of the screen cylinder 5, meeting different crushing needs, and improving the applicability of the device.

[0025] Furthermore, the sliding seat includes guide cylinders 9 that are fixedly connected at equal intervals along the circumference of the rotating shaft 12. The end of the slide rod 10 away from the screen cylinder 5 is slidably limited inside the guide cylinder 9 and is elastically connected to the guide cylinder 9 by a spring 11.

[0026] The guide cylinder 9 provides guidance and limit for the sliding of the slide rod 10, ensuring the stability of the slide rod 10's movement; the spring 11 enables the slide rod 10 to reset after being subjected to external force, and also plays a certain role in buffering, reducing the impact of vibration and impact on the device.

[0027] Furthermore, the rotating shaft 12 has a tubular structure, and the linkage assembly includes a bidirectional threaded rod 21 coaxially rotatably connected inside the rotating shaft 12. Both ends of the bidirectional threaded rod 21 are threadedly connected to threaded blocks 17. The rotating shaft 12 has multiple guide grooves 27 circumferentially and extends axially along the rotating shaft 12. The tool holder 3 is connected to a hinge seat 28 in the middle. Two connecting rods 25 are hinged to one end of the hinge seat 28. The other ends of the two connecting rods 25 pass through the guide grooves 27 and are hinged to the corresponding threaded blocks 17. One end of the bidirectional threaded rod 21 extends out of the rotating shaft 12 and is connected to a clutch assembly. The clutch assembly is used to control the synchronous rotation or relative rotation of the bidirectional threaded rod 21 and the rotating shaft 12.

[0028] Specifically, bearings are welded to both ends of the rotating shaft 12, and the non-threaded ends of the bidirectional threaded rod 21 are rotatably connected to the rotating shaft 12 through the bearings.

[0029] The clutch assembly enables relative rotation between the bidirectional threaded rod 21 and the rotating shaft 12. The rotation of the bidirectional threaded rod 21 drives the threaded block 17 to move axially. Through the transmission of the connecting rod 25 and the hinge seat 28, the radial extension and retraction of the cutter holder 3 is realized, thereby adjusting the distance between the crushing cutter group and the inner wall of the screen cylinder 5. The clutch assembly allows control over the rotational relationship between the bidirectional threaded rod 21 and the rotating shaft 12 to meet the needs of different crushing conditions.

[0030] Furthermore, the clutch assembly includes a turntable 20 and a brake. The turntable 20 is rotatably connected to the end of the rotating shaft 12 and fixedly connected to the end of the bidirectional threaded rod 21. The brake includes a hydraulic rod 23, and the output end of the hydraulic rod 23 is connected to a brake pad 22 that matches the turntable 20.

[0031] The hydraulic rod 23 controls the contact or separation between the brake pad 22 and the turntable 20, thereby achieving synchronous or relative rotation between the bidirectional threaded rod 21 and the rotating shaft 12. This makes operation convenient and control precise.

[0032] Furthermore, it also includes a grinding mechanism, which is set between the outer cylinder 1 and the sieve cylinder 5. The grinding mechanism includes a grinding component and a driving component. The grinding component includes a grinding cylinder 2 coaxially sleeved outside the sieve cylinder 5. One side of the grinding cylinder 2 is rotatably connected to the end of the outer cylinder 1. A grinding blade assembly is set between the grinding cylinder 2 and the sieve cylinder 5. The grinding blade assembly is used to grind the chili flakes and form chili powder. The cylinder wall of the grinding cylinder 2 is provided with multiple holes for the chili powder to pass through.

[0033] In one embodiment, the grinding blade assembly includes a plurality of second grinding heads 16 and a plurality of first grinding heads 15. The plurality of second grinding heads 16 are arranged on the outer wall of the sieve cylinder 5, and the plurality of first grinding heads 15 are arranged on the inner wall of the grinding cylinder 2.

[0034] The grinding blade assembly between grinding cylinder 2 and sieve cylinder 5 further grinds the crushed chili flakes. This secondary processing grinds the chili flakes into a finer chili powder, significantly improving the product's fineness and quality, and meeting the market's demand for high-quality chili powder.

[0035] The holes in the grinding cylinder 2 facilitate the passage of chili powder, enabling the collection of the ground chili powder. This significantly improves the fineness and quality of the product, meeting the market demand for high-quality chili powder.

[0036] Furthermore, the driving component includes a first motor 18 mounted on the outer cylinder 1. The output end of the first motor 18 passes through the cylinder wall of the outer cylinder 1 and is connected to a gear 7. An external gear ring 6 is fixedly sleeved on the outer wall of the grinding cylinder 2, and the external gear ring 6 meshes with the gear 7.

[0037] The power of the first motor 18 is transmitted to the grinding cylinder 2 through the meshing transmission of gear 7 and external gear ring 6, which drives the grinding cylinder 2 to rotate and realize the grinding of chili flakes. The transmission method is simple and reliable and the transmission ratio is stable.

[0038] Furthermore, the crushing blade assembly includes two sets of blade heads 4, which are respectively located on both sides of the blade holder 3, and each set of blade heads 4 includes multiple blade heads 4.

[0039] The addition of two sets of blades increases the number of crushing blades and the crushing area, improving the efficiency of chili crushing and enabling the dried chili raw material to be crushed into chili pieces more quickly.

[0040] Furthermore, the bottom area of ​​the sieve cylinder 5 is provided with multiple sieve holes 14, and multiple electric ceramic heating elements 26 are embedded in the sieve cylinder 5. The multiple electric ceramic heating elements 26 are connected to the temperature controller.

[0041] The sieve hole 14 is designed so that the chili flakes that meet the particle size requirements after crushing can pass through the sieve hole 14 into the space between the outer cylinder 1 and the sieve cylinder 5, which facilitates subsequent grinding and collection, and realizes the screening of chili flakes.

[0042] After the chili pepper raw material enters the sieve cylinder 5, multiple electric ceramic heating elements 26 embedded in the cylinder wall begin to operate, generating heat to dry the chili pepper raw material. Moisture is one of the key factors affecting the toughness of the chili pepper raw material. As the temperature rises, the moisture in the chili pepper raw material gradually evaporates, and the internal moisture content of the raw material decreases significantly. When the moisture content decreases to a certain level, the chili pepper raw material gradually becomes brittle, creating favorable conditions for subsequent crushing and grinding processes.

[0043] The thermostat can precisely control the temperature of the ceramic heating element 26, preventing excessively high or low temperatures from affecting the chili raw materials.

[0044] Furthermore, a discharge box 13 is provided on the outer cylinder 1, and the discharge box 13 is connected to a collection box through a conduit, and a negative pressure pump is provided on the conduit.

[0045] The negative pressure pump generates negative pressure, which helps the chili flakes pass through the sieve holes 14 and the chili powder enter the inner cavity of the outer cylinder 1 through the holes on the grinding cylinder 2, and finally enter the collection box through the discharge box 13, thereby improving the collection efficiency and reducing the residue of chili powder.

[0046] The device for making chili powder provided by this invention operates as follows: Dried chili raw materials are fed into the sieve cylinder 5 through the feed hopper 8 at the top of the outer cylinder 1. The second motor 24 is started, driving the rotating shaft 12 to rotate at high speed, thereby driving multiple blade holders 3 and blades 4 mounted on it to rotate synchronously, striking and cutting the chili peppers to achieve preliminary crushing and form chili flakes. Depending on the variety of chili pepper and the required particle size, the extension of the blades 4 can be adjusted through the clutch assembly and the linkage assembly to control the crushing intensity. Specifically, when it is necessary to adjust the gap between the cutter head 4 and the inner wall of the screen cylinder 5, the hydraulic rod 23 is extended and the brake pad 22 is pushed towards the turntable 20 to stop. At this time, the rotating shaft 12 continues to rotate, while the bidirectional threaded rod 21 no longer follows the rotating shaft 12 under the constraint of the turntable 20. The bidirectional threaded rod 21 and the rotating shaft 12 rotate relative to each other, which causes the two threaded blocks 17 to move closer or further apart. When the two threaded blocks 17 move closer to each other, under the linkage of the connecting rod 25, the cutter holder 3 drives the cutter head 4 to move closer to the inner wall of the screen cylinder 5.

[0047] During the crushing process, the electric ceramic heating element 26 can be activated to gently heat the material inside the screen cylinder 5 and remove moisture. The chili flakes, crushed to a sufficiently small size, fall through the screen holes 14 on the screen cylinder 5 into the annular chamber between the grinding cylinder 2 and the screen cylinder 5 under the action of centrifugal force and gravity.

[0048] The first motor 18 is started, driving the grinding cylinder 2 to rotate around the sieve cylinder 5 through the meshing of gear 7 and external gear ring 6. The grinding blades on the inner wall of the grinding cylinder 2 move relative to the outer wall of the sieve cylinder 5, crushing and grinding the chili flakes that fall into it, turning them into finer chili powder. At the same time, the negative pressure pump is started, generating suction at the discharge box 13. Under the action of negative pressure, the fine chili powder produced by grinding passes through the holes in the wall of the grinding cylinder 2, is sucked into the discharge box 13, and is then transported to the collection box through a conduit for collection.

[0049] The entire process achieves automated and continuous operation of chili pepper crushing, drying, screening, grinding, and collection, which is highly efficient, with adjustable particle size and good finished product quality.
