Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a device for removing residue from L-carnitine coffee powder semi-finished products. Background Technology

[0002] L-carnitine coffee powder is a health drink that combines L-carnitine and coffee. It is widely used in fitness, weight loss, and mental alertness. L-carnitine is a compound that exists naturally in the human body. It can help fatty acids enter the mitochondria for oxidation and decomposition, thereby promoting fat burning. In the production process of L-carnitine coffee powder, the handling and processing of raw materials is one of the key steps, especially the removal of coffee powder residue. Removing impurities and large particles not only improves the taste and quality of the product, but also ensures its safety.

[0003] Patent CN215542473U discloses a coffee powder sieve, which includes a receiving tray and a sieve tray. The receiving tray is detachably connected to the bottom of the sieve tray. In use, the ground coffee powder is poured into the sieve tray, and the entire coffee powder sieve is shaken left and right by hand. Fine powder falls into the receiving tray, while coarse powder is filtered out and left in the sieve tray, which facilitates the separation of coarse and fine coffee powder, thereby obtaining the desired uniform and fine coffee powder. However, this patent has obvious limitations. First, manual operation is time-consuming and inefficient. Second, the long-term shaking work increases the burden on the worker and makes it difficult to maintain the consistency and stability of operation, affecting the quality of the final product.

[0004] Therefore, there is an urgent need in the market for a highly efficient and automated L-carnitine coffee powder semi-finished product residue removal device. Utility Model Content

[0005] To overcome the problems of low efficiency and high labor intensity of existing patented manual screening methods, this utility model provides a highly efficient and automated L-carnitine coffee powder semi-finished product residue removal device.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a device for removing residue from L-carnitine coffee powder semi-finished products, comprising a receiving box with a circular hole at the center of its top. A receiving frame is installed inside the box, and a first support frame is fixed to the top of the receiving box. A motor is fixedly mounted on the top of the support frame via a support plate. The output shaft of the motor is connected to a connecting shaft, and a feeding hopper is slidably mounted on the connecting shaft. The feeding hopper is located directly above the circular hole, and a screening hopper is provided inside the feeding hopper. A guide plate is fixed to the first support frame, providing vertical movement guidance for the feeding hopper. A limiting barrel is fitted around the outside of the feeding hopper, and the limiting barrel is connected to the bottom end of the connecting shaft. A lower inclined ring is provided at the top of the limiting barrel, and an upper inclined ring is provided at the upper part of the feeding hopper for contact and engagement.

[0007] As a further preferred embodiment, a screening screen is installed inside the receiving frame.

[0008] As a further preferred embodiment, a scraper is provided on the connecting shaft, with both ends of the scraper in close contact with the inner wall of the feed hopper. A limit plate is provided at the upper end of the connecting shaft, and symmetrically distributed first guide rods are slidably installed on the limit plate. The bottom end of the first guide rod is connected to the scraper, and a first elastic element is sleeved on the first guide rod. The two ends of the first elastic element are respectively connected to the scraper and the limit plate.

[0009] As a further preferred embodiment, a second support frame is fixedly connected to both sides of the receiving box. A second guide rod is slidably provided on each of the second support frames. The second guide rods are all provided with a movable plate. A magnet is embedded in the movable plate. A second elastic element is sleeved on the second guide rod, and its two ends are respectively connected to the second support frame and the movable plate.

[0010] As a further preferred embodiment, a corrugated sleeve is fitted onto the first guide rod, and the first elastic element is located inside the corrugated sleeve, with both ends of the corrugated sleeve connected to a scraper and a limiting plate, respectively.

[0011] As a further preferred embodiment, the bottom of the receiving box is provided with foot pads.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The device drives the limiting barrel to rotate by a motor, and the design of the upper and lower inclined rings enables the feeding barrel to generate regular up and down vibration, which helps the coffee powder to pass smoothly through the screening hopper, thereby effectively removing large particles and other impurities, improving the fineness and purity of the coffee powder. At the same time, the automated screening process reduces manual intervention, reduces labor intensity, and improves production efficiency.

[0013] 2. The scraper on the connecting shaft can be used to stir the coffee powder, ensuring that the coffee powder is evenly distributed in the feed hopper and avoiding clumping. This improves filtration efficiency and product quality. In addition, the design of the scraper in close contact with the inner wall of the feed hopper can effectively remove coffee powder adhering to the inner wall, ensuring that all coffee powder can participate in the filtration process and improving the utilization rate of raw materials.

[0014] 3. The receiving bin features a movable plate design on top, combined with a magnetic fixing and elastic reset mechanism, which can be quickly opened or closed when needed. This allows for flexible adjustment of the amount of coffee powder entering the receiving bin according to actual requirements, enabling immediate stopping of feeding when the receiving bin is full, avoiding overload, and ensuring continuity and stability in the production process.

Detailed Implementation

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5A device for removing residue from L-carnitine coffee powder semi-finished product includes a receiving box 1. The bottom of the receiving box 1 is equipped with foot pads 23, which increase the stability of the receiving box 1 and prevent displacement due to vibration during operation. A circular hole is located at the center of the top of the receiving box 1. A pull-out receiving frame 2 is installed inside the box, and a sieve 201 is installed inside the receiving frame 2 to remove small particulate impurities from the coffee powder. A first support frame 3 is fixed to the top of the receiving box 1, and a motor 5 is fixedly mounted on the top of the support frame via a support plate 4. The output shaft is connected to the connecting shaft 6, and the feeding barrel 7 is slidably mounted on the connecting shaft 6. The feeding barrel 7 is located directly above the circular hole. The feeding barrel 7 is equipped with a screening hopper 701 inside, which is used to remove large particles of impurities from the coffee powder. Two guide plates 8 are fixed on the first support frame 3, which are symmetrically distributed on the left and right. The guide plates 8 provide vertical movement guidance for the feeding barrel 7. The feeding barrel 7 is fitted with a limiting barrel 9 on the outside. The limiting barrel 9 is connected to the bottom end of the connecting shaft 6. The top of the limiting barrel 9 is provided with a lower inclined surface ring 10, and the upper part of the feeding barrel 7 is provided with an upper inclined surface ring 11 that is in contact with it.

[0023] In use, coffee powder is first poured into the sieving hopper 701. Then, the motor 5 is started, and its output shaft drives the connecting shaft 6 to rotate. This causes the limiting barrel 9 to rotate along with the connecting shaft 6. As the limiting barrel 9 rotates, the lower inclined ring 10 gradually presses against the upper inclined ring 11. Due to the inclined design of both, this pressing action forces the feeding barrel 7 to move upward along the guide plate 8. When the limiting barrel 9 rotates back to its original position, the pressure between the lower inclined ring 10 and the upper inclined ring 11 disappears, and the feeding barrel 7 will then move upward under its own gravity. The process of resetting occurs repeatedly as the limiting barrel 9 continues to rotate, causing the feeding barrel 7 to vibrate regularly up and down. This vibration helps the coffee powder pass smoothly through the screening hopper 701, while leaving large particles and other impurities inside the screening hopper 701. The coffee powder that has passed through the screening hopper 701 will then be further screened by the screening mesh 201 in the receiving frame 2 to remove smaller impurities, thereby ensuring the fineness and purity of the coffee powder. Finally, the screened coffee powder can be easily taken out by pulling out the receiving frame 2.

[0024] Example 2: Based on Example 1, please refer to... Figure 4A scraper 12 is provided on the connecting shaft 6. The front and rear ends of the scraper 12 are in close contact with the inner wall of the feed hopper 7, realizing the function of stirring the coffee powder and scraping off the residual coffee powder on the inner wall of the feed hopper 7. A limiting plate 15 is provided at the upper end of the connecting shaft 6. Two first guide rods 13 are slidably installed on the limiting plate 15. The bottom end of the first guide rod 13 is connected to the scraper 12 for supporting and guiding the scraper 12. A first elastic element 14 is sleeved on the first guide rod 13. The two ends of the first elastic element 14 are respectively connected to the scraper 12 and the limiting plate 15, providing elastic support for the scraper 12. A corrugated sleeve 22 is sleeved on the first guide rod 13, and the first elastic element 14 is located inside the corrugated sleeve 22. The two ends of the corrugated sleeve 22 are respectively connected to the scraper 12 and the limiting plate 15, so that the corrugated sleeve 22 can freely extend and retract when the first guide rod 13 slides, providing protection for the first elastic element 14 and preventing coffee powder from getting stuck.

[0025] When motor 5 starts, connecting shaft 6 rotates, driving scraper 12 to rotate as well. As scraper 12 rotates, it also moves up and down with feed hopper 7, agitating the coffee powder and ensuring its even distribution within feed hopper 7. This helps improve the filtration effect and prevents coffee powder from clumping or unevenly distributing. During the agitation process, some coffee powder may adhere to the inner wall of feed hopper 7, affecting the filtration effect. Through the close contact between scraper 12 and the inner wall, this adhered coffee powder can be effectively scraped off, ensuring that all coffee powder can participate in the filtration process, improving product utilization and purity.

[0026] Please see Figure 5 The receiving box 1 is fixedly connected to the left and right sides with second support frames 18. Each second support frame 18 is slidably provided with two second guide rods 19 symmetrically distributed front and back. The two adjacent second guide rods 19 are provided with a movable plate 16, which is used to block the round hole at the top of the receiving box 1. A magnet 17 is embedded in the movable plate 16 to provide additional fixing force when the movable plate 16 is closed. A second elastic element 20 is sleeved on the second guide rod 19, and its two ends are connected to the second support frame 18 and the movable plate 16 respectively, providing an outward restoring force for the movable plate 16. When the two movable plates 16 are closed, the second elastic element 20 is in a stretched state.

[0027] In the initial state, the two movable plates 16 are closed, blocking the round hole at the top of the receiving box 1. At this time, the second elastic element 20 is stretched. When the coffee powder is filtered and the residue is removed, the two movable plates 16 are pulled apart by external force. The restoring force of the second elastic element 20 causes the movable plates 16 to move outward out of the receiving box 1, exposing the round hole at the top of the receiving box 1, allowing the coffee powder to enter the receiving box 1. During the continuous receiving process, if the receiving box 1 is full, the two movable plates 16 can be pushed together to block the round hole at the top of the receiving box 1 again, preventing the coffee powder from entering. At this time, the second elastic element 20 is stretched again, and the magnet 17 inside the movable plate 16 attracts when it is closed, providing additional fixing force to ensure that the movable plate 16 is fixed in the closed state and prevents accidental loosening. This makes it convenient for the operator to stop the material supply in time, simplifies the subsequent operation of emptying the receiving box 1, improves work efficiency and ensures the safety of operation.

[0028] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
