Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0021] Please see Figure 1-4 A reciprocating feeding mechanism for producing spicy snacks includes a base 1, a lifting frame 4 slidably connected to the top of the base 1, and the height of the lifting frame 4 can be adjusted by an adjusting component. A material box 11 is slidably connected to the top of the lifting frame 4. Multiple feeding ports 17 are opened at the bottom of the material box 11. A connecting shaft 18 is rotatably connected between the inner walls of the two sides of the material box 11. Multiple discharge plates 19 are fixed to the connecting shaft 18 located in the feeding ports 17 by bolts. A drive component for rotating the discharge plates 19 is provided on one side of the lifting frame 4. A power component for driving the material box 11 to perform horizontal reciprocating motion is provided on one side of the lifting frame 4. In use, the seasoning is placed in the seasoning box 11, and then the lifting frame 4 is raised slightly by adjusting the component, so that the discharge port 17 of the seasoning box 11 is higher than the feed port of the mixing equipment. The power component drives the seasoning box 11 to move back and forth horizontally, changing the horizontal position of the discharge port 17. At the same time, the drive component drives the discharge plate 19 to rotate, so that the discharge plate 19 carries the seasoning to fall evenly from the discharge port 17, realizing the reciprocating sprinkling of seasoning at the feed port of the mixing equipment. This design, through the combination of the horizontal movement of the material box 11 and the rotation of the discharge plate 19, can effectively expand the spreading range of the seasoning, avoid the accumulation of seasoning in local areas, ensure more sufficient contact between the materials and seasonings in the subsequent mixing process, and improve the overall mixing uniformity. In actual production, operators can precisely adjust the speed and density of the seasoning by controlling the running speed of the power component and the rotation frequency of the drive component, according to the type and amount of seasoning required, to meet the production process requirements of different spicy strip products.

[0022] In this utility model, the adjustment component includes an electric push rod 2 fixed on the inner wall of the bottom of the base 1. The movable end of the electric push rod 2 is fixed to the lifting frame 4. A support component for protecting the electric push rod 2 is provided on one side of the base 1. When it is necessary to adjust the height of the lifting frame 4, the electric push rod 2 is activated. The extension of the electric push rod 2 will drive the lifting frame 4 to move upward, thereby changing the height of the lifting frame 4. The retraction of the electric push rod 2 will drive the lifting frame 4 to move downward. When the lifting frame 4 is low, it is convenient to feed the seasonings. When the lifting frame 4 is high, it is convenient to directly transport the seasonings to the mixing equipment, which improves the operational flexibility in the production process. In addition, the electric push rod 2 has the characteristics of fast response speed and high adjustment accuracy, which provides strong support for the continuous and automated production of spicy strips.

[0023] Furthermore, the support assembly includes a pin 3 that passes through one side of the base 1, and two sets of through holes are provided on one side of the lifting frame 4. Each set of through holes includes two insertion holes 15, and one end of the pin 3 passes through the insertion hole 15 in one set of through holes, and a nut is used to fix one end of the pin 3. When the electric push rod 2 is at its longest or shortest limit, the insertion hole 15 coincides with the positioning holes on both sides of the base 1, so that the pin 3 can be inserted into the positioning hole and the insertion hole 15 to lock the lifting frame 4 and reduce the load on the electric push rod 2. This dual fixing method can not only effectively prevent the lifting frame 4 from shifting due to vibration or accidental force during equipment operation, ensuring the stability and safety of production, but also prevent the electric push rod 2 from being under extreme stress for a long time, extending its service life and reducing the maintenance cost of the equipment. Meanwhile, the simple structure of the pin 3 and the nut makes operation convenient, allowing workers to quickly lock or unlock, further improving the work efficiency on the spicy strip production line.

[0024] It should be noted that the electric actuator 2 is existing technology, and its function and principle can be known by those skilled in the art through technical manuals or conventional experimental methods, so it will not be elaborated on here.

[0025] The drive assembly includes rollers 12 fixed at both ends of the connecting shaft 18. Friction ring sleeves 13 are bonded to the outer circumference of the rollers 12. A support frame 14 is welded to the top of the lifting frame 4, and the friction ring sleeves 13 are in contact with the support frame 14. The rollers 12 can be located below the support frame 14 or above the bottom inner wall of the support frame 14, and can be installed according to the actual situation. During the movement of the seasoning box 11, the seasoning box 11 will drive the connecting shaft 18 to move, thereby driving the roller 12 to move. Under the action of friction, the abutment 14 will cause the roller 12 to rotate, thereby completing the feeding of seasoning in the seasoning box 11 and improving the automation of seasoning spreading. This design, which uses the material box 11's own moving power to drive the discharge plate 19 to rotate, eliminates the need for an additional independent drive source, simplifies the overall structure of the equipment, reduces the number of parts, lowers the manufacturing cost and maintenance difficulty, and also improves the coordination and reliability of the mechanism's operation. The friction ring sleeve 13 can increase the friction between the roller 12 and the support frame 14, ensuring that the roller 12 rotates stably during movement and avoiding slippage that would affect the material discharge effect of the discharge plate 19. The friction ring sleeve 13 is made of polyurethane rubber, which has high wear resistance, high strength and good elasticity. It can play a buffering role when the roller 12 contacts the abutment 14, reduce the rigid collision between the two, reduce the noise and component wear during equipment operation, extend the overall service life of the drive assembly, and meet the rolling friction requirements for a long time due to its high wear resistance.

[0026] The power assembly includes a crankshaft 6 that rotates between the inner walls of both sides of the lifting frame 4. A lever arm 7 is rotatably connected to the journal of the crankshaft 6. One end of the lever arm 7 is rotatably connected to a pull rod 8 that is rotatably mounted to the bottom of the material box 11. The pull rod 8 passes through a ball bearing sleeve provided inside the lifting frame 4. The ball bearing sleeve can further reduce the friction between the pull rod 8 and the lifting frame 4, making it not only smoother but also effectively improving the stability of the pull rod 8 when it moves. A pulley 5 connected to an external power source is keyed to the outer circumference of the crankshaft 6. An external power source drives the pulley 5 to rotate, which in turn drives the crankshaft 6 to rotate, which in turn drives one end of the power arm 7 to move, thereby driving the tie rod 8 to move, and in turn driving the material box 11 to move back and forth horizontally. The crankshaft 6, the power arm 7 and the tie rod 8 are combined to form a crank connecting rod structure, which can realize the smooth reciprocating motion of the material box 11. Its transmission process has the characteristics of simple structure and reliable operation, and can effectively ensure the accuracy and stability of the material box 11 in the horizontal direction. Compared with traditional cam drive or hydraulic drive, this crank-connecting rod structure is not only cheaper to manufacture, but also easier to maintain. It is less prone to failure during long-term continuous operation, making it very suitable for scenarios with high requirements for equipment stability, such as spicy strip production. In addition, by changing the lever arm 7 of different lengths or adjusting the eccentricity of the crankshaft 6, the reciprocating stroke of the material box 11 can be flexibly changed to adapt to the width requirements of the feed inlet of different specifications of mixing equipment, further enhancing the versatility and applicability of the equipment. In practical applications, an external power source can be a servo motor equipped with an encoder. The number of rotations and rotation angle of the motor output shaft are controllable. The output shaft of the servo motor is keyed to a drive wheel that cooperates with pulley 5. The speed of pulley 5 is precisely adjusted by the control system, thereby achieving precise control of the reciprocating motion frequency of the material box 11. This ensures that the material spreading process is highly synchronized with the rhythm of other processes in the production of spicy strips, thereby improving the overall production line's collaborative efficiency.

[0027] As a further embodiment of this utility model, the top of the seasoning box 11 is provided with a cover plate 10. The cover plate 10 is made of a transparent material, preferably an acrylic plate. The transparent material design allows the staff to visually check whether the seasoning has clumped or other abnormalities without opening the cover plate 10, so as to deal with them in time and ensure that the quality of the seasoning meets the production requirements. The cover plate 10 and the seasoning box 11 are connected by a hinge, which is flexible in opening and closing. When adding seasoning, simply flip the cover plate 10 upwards. The operation is convenient. The cover plate 10 can be closed and locked with a buckle. After the cover plate 10 is closed, it can effectively prevent external dust and impurities from entering the seasoning box 11 and contaminating the seasoning, ensuring the hygiene and safety of the spicy strip production process. Alternatively, the cover plate 10 and the seasoning box 11 can be connected by a snap-fit ​​method. The cover plate 10 has a snap-fit ​​groove inside that matches the outer diameter edge of the seasoning box 11. Simply snap the cover plate 10 onto the top of the seasoning box 11 to complete the sealing of the seasoning box 11. The hinge connection method is preferred. Furthermore, during the horizontal movement of the seasoning box 11, the seasoning inside the seasoning box 11 is sealed so that the seasoning inside the seasoning box 11 can only be discharged from the discharge port 17, thus preventing the seasoning from spilling from the edge of the seasoning box 11 due to inertia during the movement and causing waste. In addition, a sealing strip can be provided at the edge of the cover plate 10. When the cover plate 10 is closed, the sealing strip can further enhance the sealing of the container 11, effectively preventing dust and odors in the workshop from entering the container 11, providing a clean storage environment for the seasonings, and meeting the hygiene standards of food production.

[0028] Furthermore, the top of the lifting frame 4 is fixed with a mounting frame 9 by bolts, and the inner wall of the top of the mounting frame 9 is fixed with at least one vision sensor 16 by bolts. The vision sensor 16 is a Cognex IS5400, and the detection end of the vision sensor 16 faces the material box 11. The vision sensor 16 can monitor the remaining amount of seasoning in the seasoning box 11 in real time. When the remaining amount of seasoning is lower than the preset threshold, the vision sensor 16 will transmit a signal to the control system. The control system will then turn off the external power source and stop the seasoning box 11 from dispensing, thus saving energy consumption. Meanwhile, the vision sensor 16 can also monitor the accumulation status of seasonings in the seasoning box 11. If it finds that the seasonings are bridging or clumping, which affects the feeding process, it can promptly feed back to the control system so that the operator can take appropriate measures to handle the situation and ensure the smoothness of the feeding process. The addition of this real-time monitoring function not only reduces the workload of manual inspections and lowers the risk of human error, but also provides data support for intelligent management of the production process, helping managers to more accurately control the production rhythm and material consumption.

[0029] The specific steps for using this utility model are as follows: Place the seasoning into the seasoning box 11 and start the electric push rod 2. The extension of the electric push rod 2 will drive the lifting frame 4 to move upward, thereby changing the height of the lifting frame 4. When the movable end of the electric push rod 2 moves to its maximum limit, the insertion hole 15 coincides with the positioning holes opened on both sides of the base 1, so that the pin 3 can be inserted into the positioning hole and the insertion hole 15 to lock the lifting frame 4. An external power source drives the pulley 5 to rotate, which in turn drives the crankshaft 6 to rotate, which in turn drives one end of the power arm 7 to move, thereby driving the pull rod 8 to move, and then driving the material box 11 to move back and forth horizontally. During the movement of the material box 11, the material box 11 will drive the connecting shaft 18 to move, which in turn drives the roller 12 to move. Under the action of friction, the abutment 14 will cause the roller 12 to rotate, thereby completing the uniform falling of the seasoning in the material box 11. This achieves the reciprocating sprinkling of the seasoning at the feed inlet of the mixing equipment, effectively expanding the sprinkling range of the seasoning, avoiding the accumulation of seasoning in local areas, ensuring more sufficient contact between the material and the seasoning in the subsequent mixing process, and improving the overall mixing uniformity.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
