Description

Technical Field

[0001] This utility model relates to the field of chili processing technology, specifically to a feeding mechanism for chili processing. Background Technology

[0002] Chili peppers are annual herbaceous plants belonging to the genus Capsicum in the Solanaceae family. They originated in the tropical regions of Central and South America and were introduced to China in the late 15th century. Today, they are cultivated throughout the country. Every 100 grams of chili peppers contains up to 188 milligrams of vitamin C, ranking first among vegetables. They are also rich in vitamin B, carotene, and minerals such as calcium and iron. Spicy foods have functions such as sterilization, preservation, flavoring, nutrition, and warming. They have positive effects on humans, such as warming the stomach and relieving cold, enhancing appetite, and promoting digestion. Therefore, chili peppers have become an indispensable food in people's daily lives.

[0003] To make them easier for people to eat, chili peppers are often made into chili powder, chili threads, and chili sauce. All of these products require a chopping step during processing. In existing chili chopping devices, chili peppers need to be added manually when feeding. If too many are added at once, the machine cannot chop all the chili peppers. This requires controlling the amount added, but manual control is too time-consuming and labor-intensive.

[0004] Therefore, we propose a feeding mechanism for chili processing to solve the above problems. Utility Model Content

[0009] A feeding mechanism for chili processing includes a hopper, a material level sensor installed on the inner top of the hopper, a spiral pusher shaft installed inside the hopper, a support fixed to the outer side of the hopper, and a geared motor fixed on the support. The output shaft of the geared motor is connected to the spiral pusher shaft via a coupling. The bottom of the hopper has a discharge port, and a dial wheel is installed in the discharge port. A servo motor is installed on the outer side of the discharge port, and a toothed drive wheel is installed on the output shaft of the servo motor. A driven wheel is installed at the end of the dial wheel, and the driven wheel is meshed with the toothed drive wheel.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figures 1-3 As shown in the figure, an embodiment of the present invention provides a feeding mechanism for chili processing, including a hopper 1, a material level sensor 2 installed on the inner top of the hopper 1, a spiral pusher shaft 3 installed inside the hopper 1, a support 4 fixed on the outer side of the hopper 1, and a reduction motor 5 fixed on the support 4. The output shaft end of the reduction motor 5 is connected to the spiral pusher shaft 3 through a coupling. The bottom of the hopper 1 is provided with a discharge port 6, and a dial wheel 7 is installed in the discharge port 6. A servo motor 8 is installed on the outer side of the discharge port 6, and a toothed drive wheel 9 is installed on the output shaft of the servo motor 8. A driven wheel 10 is installed at the end of the dial wheel 7, and the driven wheel 10 is meshed with the toothed driving wheel 9. The screw pusher shaft 3 is driven to rotate by the geared motor 5. Under the action of the material's gravity, the material rolls downward along the spiral surface of the blade and moves axially, so that the material is fed into the discharge port 6. The dial wheel 7 is driven by the servo motor 8 to realize intermittent motion control, ensuring that the chili peppers are dropped at a time. This can avoid the blockage caused by adding too many chili peppers at once. The entire production process is directly controlled by the PLC, eliminating the need for manual feeding, saving time and labor, not only speeding up the production process, but also improving product quality and system stability.

[0027] like Figure 2 As shown, in some embodiments, a PLC controller 11 and an audible and visual alarm 12 are respectively installed on the outside of the hopper 1, and the audible and visual alarm 12 is electrically connected to the PLC controller 11. The PLC controller 11 is a programmable logic controller, which is a digital computing and operating electronic system specifically designed for industrial applications. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations. It controls various types of mechanical equipment or production processes through digital or analog input and output. The audible and visual alarm 12 is a device that provides safety warnings by simultaneously emitting sound and light signals, promptly reminding personnel to take countermeasures when abnormal situations occur.

[0028] like Figure 1As shown, in some embodiments, the level sensor 2, the geared motor 5, and the servo motor 8 are electrically connected to the PLC controller 11. The level sensor 2 is mainly used to monitor the height and interface position of solid materials in the container. It can sense the material status in real time through continuous or point measurement to ensure the safety and efficiency of the production process.

[0029] like Figure 1 As shown, in some embodiments, the bottom surface of the hopper 1 is an inclined surface, and the spiral pusher shaft 3 is parallel to the bottom surface of the hopper 1. The spiral pusher shaft 3 is driven to rotate by the geared motor 5. Under the action of the material's gravity, the material rolls downward along the spiral surface of the blade and moves axially. The inclined surface is to facilitate the feeding of the material into the discharge port 6.

[0030] like Figure 3 As shown, in some embodiments, the spiral pusher shaft 3 is installed at both ends inside the hopper 1 by bearings, and the spiral pusher shafts 3 are connected in pairs by belt drive. Under the action of the coupling, the geared motor 5 drives the spiral pusher shaft 3 to rotate. Under the action of belt drive, the spiral pusher shaft 3 on one side drives the spiral pusher shaft 3 on the other side to rotate.

[0031] like Figure 1 As shown, in some embodiments, the bottom end of the spiral pusher shaft 3 extends into the discharge port 6, and the dial wheel 7 is installed in the discharge port 6 through a bearing and close to the bottom end of the spiral pusher shaft 3. When the material is fed into the discharge port 6, the dial wheel 7 is driven by the servo motor 8 to achieve intermittent motion control (the toothed driving wheel 9 and the driven wheel 10 form an incomplete gear mechanism, specifically, it is an intermittent motion mechanism evolved from a common involute gear mechanism. Its basic structural forms are divided into external meshing and internal meshing. According to the structural characteristics of the incomplete gear mechanism, when the toothed part of the driving wheel meshes with the teeth of the driven wheel 10, it pushes the driven wheel to rotate 10. When the toothed part of the driving wheel disengages from the driven wheel 10, the driven wheel 10 stops moving. Therefore, when the driving wheel rotates continuously, the driven wheel 10 obtains intermittent motion that moves and stops).

[0032] like Figure 1 As shown, in some embodiments, the top of the hopper 1 is fitted with a hinged cover 13, and the cover 13 is fitted with a viewing window 14. During the production process, closing the cover 13 can prevent dust and other impurities from falling in. The viewing window 14 is for direct observation of the material in the hopper 1.

[0033] like Figure 1 As shown, in some embodiments, the bottom of the hopper 1 is provided with a mounting surface 15, and the mounting surface 15 is provided with a fixing hole 16. The mounting surface 15 can be used with bolts through the fixing hole 16 to achieve precise positioning and quick installation of the feeding mechanism, such as the installation with a chili chopping device.

[0034] In use, the screw feeder shaft 3 is driven to rotate by the geared motor 5. Under the action of the material's gravity, the material rolls downward along the spiral surface of the blade and moves axially, so that the material is fed into the discharge port 6. The intermittent motion control is achieved by the servo motor 8 driving the dial wheel 7 to ensure that the chili peppers are dropped at a time. This can avoid the blockage caused by adding too many chili peppers at once. The entire production process is directly controlled by the PLC, eliminating the need for manual feeding, saving time and labor. This not only speeds up the production process but also improves product quality and system stability.

[0035] In summary, the screw conveyor shaft 3 is driven to rotate by the geared motor 5. Under the action of gravity, the material rolls downward along the spiral surface of the blades and moves axially, so that the material is fed into the discharge port 6. The intermittent motion control is achieved by the servo motor 8 driving the dial wheel 7 to ensure that the chili peppers are dropped at a time. This avoids the blockage caused by adding too many chili peppers at once. The entire production process is directly controlled by the PLC, eliminating the need for manual feeding, saving time and labor. This not only speeds up the production process but also improves product quality and system stability.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
