Description

Technical Field

[0001] This application relates to the field of food machinery technology, specifically to a multi-functional feeder. Background Technology

[0002] Currently, many food production enterprises, cake shops, and bakeries add toppings (such as sesame seeds, crushed peanuts, crushed walnuts, sunflower seeds, crushed oats, crushed seaweed, chopped vegetables, and other food additives) to their products to improve their taste and appearance. The topping process relies heavily on manual labor. Manually sprinkling sesame seeds is extremely inefficient, with limited hourly production capacity, making it difficult to meet the demands of large-scale production. Furthermore, manual operation is affected by factors such as operator experience and fatigue, making it difficult to ensure consistent weight and placement each time. This leads to significant differences in the evenness of topping distribution within the same batch of products, and problems such as toppings falling off due to misplacement, seriously affecting the stability and consistency of product quality, thus damaging product quality and resulting in topping waste.

[0003] To address the shortcomings of manual ingredient application in food production, some equipment manufacturers have adopted simple mechanical ingredient application devices. However, these rudimentary devices struggle to guarantee the accuracy and uniformity of the application range, often resulting in excessive or insufficient ingredients, misaligned application, insufficient production efficiency, and negative impacts on the overall quality and taste of the food, as well as ingredient waste.

The multi-functional material spreading mechanism is used to spread material along its path.

[0007] The multi-functional feeding mechanism includes a hopper, a pushing component, and a discharge cylinder.

[0031] See attached document Figures 1 to 4This application provides a multi-functional material spreading machine, including a frame 1, a feeding mechanism 2, a multi-functional material spreading mechanism 3, a servo motor system 4, and a PLC control system 5. The feeding mechanism 2 and the multi-functional material spreading mechanism 3 are mounted on the frame 1. The feeding mechanism 2 is accurately controlled by the servo motor system 4 to adjust its running speed and positioning, allowing it to accurately transport materials to the multi-functional material spreading mechanism 3 at a set speed, one by one. A photoelectric switch 9 detects the materials and transmits a signal to the PLC control system 5, which then precisely controls the multi-functional material spreading mechanism 3 to spread the materials as they pass. Figure 5 and Figure 6 As shown, the multi-functional material spreading mechanism 3 includes a hopper 306, a pushing component and a discharge cylinder 307. The material core 305 of the pushing component retracts below the hopper 306, loads auxiliary materials, and extends to the discharge cylinder 307 to discharge the materials. The discharge cylinder 307 is located above the feeding mechanism 2. The PLC control system 5 adopts a Delta control system. On the one hand, the PLC control system 5 controls the servo motor system 4, which accurately controls the running speed and positioning of the feeding mechanism 2. This allows the feeding mechanism 2 to accurately transport the material product to the underside of the multi-functional spreading mechanism 3 at a set speed. The photoelectric switch 9 detects the material product and sends a signal to the PLC control system, which controls the pushing component to drop the auxiliary material quantitatively from the discharge cylinder 307 onto the material surface. Thus, the auxiliary material is precisely and quantitatively spread on the material surface. Furthermore, the central loading hole of the material core 305 of the pushing component is a fixed volume hole. The telescopic cyclical movement of quantitative loading under the hopper 306 and discharging from the discharge cylinder 307 ensures that the amount of material discharged each time is the same. This can control the error in the amount of auxiliary material used to a very small range, significantly improve the stability of product quality, and ensure the consistent quality of each batch of products.

[0032] Specifically:

[0033] like Figures 5 to 6 As shown, the feeding assembly includes an automatic telescopic component 301, a valve plate 302, and a core seat 303. The automatic telescopic component 301 and the core seat 303 are fixed to a mounting base plate 304, which is connected to the frame 1 by screws and its height can be adjusted according to the material and product requirements. A telescopic valve plate 302 is located in the middle of the core seat 303, and a material core 305 is mounted at the front end of the valve plate 302. The material core 305 has a fixed-volume loading hole at its center. The automatic telescopic component 301 is located on one side of the core seat 303. The valve plate 302 is connected to the automatic telescopic component 301 via a fisheye connector 309. The telescopic movement of the automatic telescopic component 301 drives the valve plate 302 and the material core 305 to reciprocate, loading auxiliary materials below the hopper 306 and pushing them to the discharge cylinder 307 for discharge. The automatic telescopic component 301 can be any one of an electric push rod, a pneumatic cylinder, or a hydraulic cylinder.

[0034] Meanwhile, a hopper mounting plate 308 is provided on the top of the core seat 303. The hopper 306 is connected to the hopper mounting plate 308 by fasteners. The hopper mounting plate 308 is provided with a discharge port, which connects the core 305 and the hopper 306. When the valve plate 302 drives the core 305 to retract to the discharge port of the hopper mounting plate 308, the auxiliary material falls from the hopper 306 and is loaded into the loading hole of the core 305. A discharge port is provided at the bottom of the core seat 303. When the valve plate 302 pushes the loading hole of the core 305 to the discharge port, the discharge port connects the loading hole of the core 305 and the discharge channel of the discharge cylinder 307. The auxiliary material falls onto the product under gravity. The staggered arrangement of the loading port and discharge port, through the structural isolation of the core seat 303, prevents other auxiliary materials from following below the hopper 306, ensuring that the auxiliary material is quantitatively loaded into the loading hole of the core 305 and moves to the discharge port for discharge. Imagine that when the automatic telescopic component 301 is in the retracted state, the auxiliary material falls from the discharge port into the loading hole of the material core 305. When the automatic telescopic component 301 extends, it pushes the material core 305 on the valve plate 302. When the loading hole of the material core 305 is located at the bottom discharge port of the core seat 303, the loading hole of the material core 305 and the discharge cylinder 307 form a discharge channel. The auxiliary material falls from the loading hole of the material core 305 through the bottom discharge port of the core seat 303 into the discharge cylinder 307 and is scattered on the surface of the material below. As the material core 305 moves towards the discharge cylinder 307, it gradually closes the discharge port to prevent further material feeding. After one feeding and discharging cycle, the automatic telescopic component 301 retracts, and the loading hole of the material core 305 returns to the discharge port to quantitatively load the auxiliary material, thus ensuring that the amount of auxiliary material used each time is basically consistent. This cycle is repeated to achieve quantitative and precise material feeding.

[0035] In the above, the hopper 306 adopts a conical shape, which can generate downward central pressure by the accumulation of auxiliary materials, ensuring smooth material discharge.

[0036] In a preferred embodiment, the components of the multi-functional dispensing mechanism 3 are arranged in a series of interconnected parts, making the automatic telescopic component 301, valve plate 302, core seat 303, mounting base plate 304, material core 305, hopper 306, discharge cylinder 307, hopper mounting plate 308, and fisheye connector 309 replaceable. Depending on the type and quantity of the auxiliary material, replacing the material core 305 with different models can typically meet the dispensing needs of most product auxiliary materials. For special product dispensing, more different models of other components of the multi-functional dispensing mechanism 3 may be replaced to meet the dispensing needs of various auxiliary materials and materials with higher weights.

[0037] In this embodiment, the feeding mechanism 2 includes a set of parallel small roller assemblies 202, a large roller assembly 201 triangularly distributed with the small roller assemblies 202, and a conveyor belt 204 connecting the large roller assembly 201 and the small roller assembly 202. It also includes a pair of transition roller assemblies 203 located between the large roller assembly 201 and the small roller assembly 202, serving to tension the conveyor belt 204 between them. A servo motor system 4 is also provided on the frame 1. The servo motor system 4 drives the feeding mechanism 2. The servo motor system 4 is equipped with a servo motor, a reducer, and transmission components (not limited to gear transmission and synchronous sprocket transmission). The servo motor system is connected to the large roller assembly through the transmission components to provide power to the feeding mechanism 2.

[0038] Meanwhile, a slag collection mechanism is provided at the discharge end of the feeding mechanism 2. This mechanism includes a slag box 6 fixed to the bottom of the discharge end of the feeding mechanism 2 on the frame 1. A scraper 8 is installed inside the slag box 6, and the scraper 8 is in contact with the conveyor belt. A slag tray 7 is also installed outside the slag box 6, extending from the discharge end of the feeding mechanism 2. Understandably, when the equipment is operating, any residue that falls onto the conveyor belt 204 is scraped into the slag box 6 by the scraper 8 for easy cleaning and to ensure normal equipment operation.

[0039] Of course, conventionally, the PLC control system 5 is used to control the servo motor system 4, the feeding mechanism 2, and the multi-functional spreading mechanism 3 to work together to achieve fully automated control and improve work efficiency.

[0040] In summary, the multi-functional material spreader provided in this application has the following advantages:

[0041] Precise quantification: It can control the error of auxiliary material dosage within a very small range, significantly improve the stability of product quality, and ensure the consistent quality of each batch of products.

[0042] Precise application: This ensures that sesame seeds are precisely applied to the surface of the food, greatly enhancing the product's appearance and market appeal.

[0043] Highly efficient and convenient: The highly automated design makes it easy to operate, greatly improving production efficiency, effectively reducing production costs and manual labor, and enhancing the economic benefits of enterprises.

[0044] Save on auxiliary materials: The product auxiliary materials are quantitatively and precisely applied, resulting in minimal spillage and waste, thus reducing costs and increasing efficiency.

[0045] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
