Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to an automatic packaging device for food processing. Background Technology

[0002] In the food processing industry, with the continuous expansion of production scale and the increasing market demand for product packaging quality, the traditional packaging method uses gravity feeding from the silo for filling, and then sensors for detection and control to achieve quantitative packaging. For some granular or powdery food raw materials, such as white sugar, clumping is prone to occur during the packaging process. If not handled properly, it will lead to uneven filling, affecting the appearance and quality of the product, and may even cause customer complaints due to weight errors that do not meet the standards. In addition, the traditional packaging method is difficult to accurately control the weight of each bag of food, often resulting in overweight or underweight situations. Utility Model Content

[0003] To address the problem of precise weight control in traditional food processing packaging where materials are directly fed into the silo by gravity, this application provides an automatic packaging device for food processing.

[0004] The automatic packaging device for food processing provided in this application adopts the following technical solution:

[0005] An automatic packaging device for food processing includes a frame with a storage bin on the frame. A auger conveying assembly is provided at the discharge end of the storage bin. The auger conveying assembly includes a housing mounted on the storage bin, a perforated plate on the inner side of the housing, and a conveying auger on the perforated plate. The conveying auger includes spiral blades on both sides of the perforated plate. A quantitative discharge assembly is provided at the discharge end of the housing, and the quantitative discharge assembly includes a weighing device mounted on the frame, with a temporary storage bin on the weighing device.

[0006] Preferably, the conveying auger further includes a rotating shaft disposed on the housing, one end of which passes through the housing and is connected to a power motor, the power motor being mounted on the frame.

[0007] Preferably, a buffer ring is provided on the side of the housing near the discharge port, and an inclined surface is provided on the side of the buffer ring near the filter plate.

[0008] Preferably, the weighing device includes a support ring fitted at the lower end of the temporary storage bin, and a plurality of pressure sensors arranged in a ring are provided at the lower end of the support ring, the pressure sensors being mounted on the frame.

[0009] Preferably, a solenoid valve is provided at the bottom of the temporary storage compartment.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] By using the combined use of a storage silo, an auger conveying assembly, and a quantitative discharging assembly, and by setting the weight parameters of each bag of white sugar in the control system, after the device is started, the white sugar in the storage silo begins to be conveyed under the action of the auger conveying assembly. The weighing device monitors the weight in real time. When the preset weight is reached, the auger conveying assembly stops conveying, the solenoid valve opens, and the white sugar falls into the packaging material below the hopper. During the conveying process, the filter plate intercepts the clumps of white sugar, ensuring the uniformity and accuracy of filling. Compared with the existing technology, it has the advantages of high packaging precision and good packaging effect. Attached Figure Description

Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses an automatic packaging device for food processing. (Refer to...) Figure 1-3 An automatic packaging device for food processing is mainly composed of a frame 1, a storage bin 2, an auger conveying assembly 3, and a quantitative discharging assembly 4. The components work together to achieve efficient and precise packaging of food raw materials, meet the strict requirements of the food processing industry for packaging quality and efficiency, and improve the automation level of the production process and the consistency of product packaging.

[0018] Reference Figure 1The frame 1 serves as the supporting structure for the entire device, providing a stable installation foundation for the storage bin 2, the auger conveying assembly 3, and the quantitative discharging assembly 4. This ensures that the relative positions of each component remain stable during operation, preventing shaking or displacement from affecting the packaging accuracy and normal operation of the equipment. Its structural design has undergone strength calculations and optimization, possessing sufficient load-bearing capacity to withstand various forces during device operation, including the weight of the material, motor vibration, and reaction forces during mechanical transmission, ensuring the reliability and durability of the entire packaging device.

[0019] Reference Figure 1 The storage bin 2 is used to store food raw materials to be packaged. Its discharge end is tightly connected to the auger conveyor assembly 3 to ensure that the raw materials can smoothly enter the conveying process. The capacity and shape of the storage bin 2 are designed according to the common food processing production scale and raw material characteristics, which can meet the production needs of a certain batch while ensuring the flowability of raw materials in the bin and avoiding blockage or poor discharge. Its interior is usually smoothed to reduce the friction between the raw materials and the bin walls, so that the raw materials can flow more smoothly to the auger conveyor assembly 3 and improve the conveying efficiency of the entire device.

[0020] Reference Figure 2The auger conveying assembly 3 is a key component for raw material conveying and preliminary processing. The housing 301, mounted on the storage hopper 2, provides a closed working space for the conveying auger 304 and the filter plate 303, preventing leakage of raw materials during conveying and protecting internal components from external contaminants, ensuring the hygiene and safety of food processing. The filter plate 303, located inside the housing 301, has carefully designed filter holes of varying sizes and distribution to effectively trap clumps in the raw materials. During the storage and transportation of food raw materials, factors such as humidity and temperature may cause some materials to clump. If these clumps directly enter the packaging, they will affect product quality and packaging uniformity. The filter plate 303 intercepts clumps above it, ensuring that only uniform raw materials pass through the filter holes into the area below the conveying auger 304, laying the foundation for subsequent precise quantitative discharge. The conveying auger 304 consists of an auger shaft 3041 and auger blades 3042. One end of the auger shaft 3041 passes through the housing 301 and is connected to the power motor 302, which is mounted on the frame 1. When the power motor 302 starts, the auger shaft 3041 drives the auger blades 3042 to rotate. The gap between the auger blades 3042 and the inner wall of the housing 301, as well as the spiral shape design of the blades, allows the raw material to move along the housing 301 towards the discharge end under the push of the blades, achieving stable material conveying. A buffer ring 305 is provided on the side of the housing 301 near the discharge port. Its inclined surface slows down the speed at which the raw material enters the filter plate 303 area, preventing blockage or uneven passage caused by the raw material impacting the filter plate 303 too quickly. This further optimizes the material conveying process and improves the working efficiency and stability of the entire auger conveying assembly 3.

[0021] Reference Figure 3 The quantitative dispensing component 4 is responsible for precisely controlling the packaging weight of each bag of food. A support ring in the weighing device 402 is fitted onto the lower end of the temporary storage bin 401, and several ring-shaped pressure sensors at its lower end are mounted on the frame 1. This structural design allows for precise sensing of weight changes in the raw materials within the temporary storage bin 401. The pressure sensors transmit weight signals to the control system in real time, and the control system makes judgments and controls based on preset weight parameters. The solenoid valve 403 at the bottom of the temporary storage bin 401 controls the dispensing of raw materials under the command of the control system. When the weighing device 402 detects that the raw materials in the temporary storage bin 401 have reached the preset weight, the control system sends a signal to stop the power motor 302 and the conveying auger 304 from conveying raw materials. Simultaneously, the solenoid valve 403 opens, and the raw materials in the temporary storage bin 401 quickly fall into the packaging material below the hopper under gravity, completing a precise packaging process. The entire quantitative dispensing component 4 ensures that the packaging weight of each bag of food meets the set requirements through precise weighing and sensitive control, greatly improving packaging accuracy and product quality consistency, and meeting the market's demand for standardized food packaging.

[0022] The implementation principle of an automatic packaging device for food processing according to an embodiment of this application is as follows: In the food processing workshop, the food raw materials to be packaged, such as white sugar, are poured into the storage bin 2. The capacity and shape design of the storage bin 2 should ensure that the raw materials can flow smoothly into the auger conveying component 3 to avoid blockage.

[0023] The operator inputs the required weight parameters for each bag of food into the control system. These parameters will serve as the basis for control during the subsequent packaging process. After the device is started, the power motor 302 begins to work, driving the auger shaft 3041 to rotate through a coupling or other connection method. The auger blades 3042 on the auger shaft 3041 rotate accordingly, generating an axial thrust on the food raw materials, causing the raw materials to move along the shell 301 towards the discharge end.

[0024] When the raw material passes through the filter plate 303, because the size of the filter holes on the filter plate 303 is smaller than the size of the clumped raw material, the clumped raw material will be blocked above the filter plate 303, while the raw material with uniform particles can pass through the filter holes smoothly into the temporary storage bin 401. This process effectively prevents clumped raw material from entering the packaging, ensuring the quality of each bag of food and the uniformity of filling.

[0025] During the process of raw materials entering the temporary storage bin 401, the pressure sensor of the weighing device 402 monitors the total weight of the temporary storage bin 401 and the raw materials inside in real time. The pressure sensor converts the weight signal into an electrical signal and transmits it to the control system, which analyzes and processes these signals in real time. When the weight reaches the preset value, the control system immediately issues a command to stop the power motor 302, stop the conveying auger 304 from conveying raw materials, and simultaneously control the solenoid valve 403 to open. At this time, the raw materials in the temporary storage bin 401 fall into the prepared packaging material below under the action of gravity through the solenoid valve 403, completing a precise packaging operation.

[0026] After packaging is completed, solenoid valve 403 closes and motor 302 restarts to continue the next packaging process. This cycle repeats continuously, achieving automatic, efficient, and precise packaging of food.
