[0002] In the field of feed industrial production (including the processing and manufacturing of feed raw materials and by-products), the problem of feed mildew caused by hot filling bags is gradually increasing. During short-term storage, the temperature and humidity are too high, creating favorable conditions for the growth of mold. After mildew, unpleasant musty smells and harmful toxins are produced, affecting the palatability of livestock and poultry, resulting in a decrease in feed intake, or even refusal to eat, and flowing onto the tables of human society, bringing food safety problems and causing huge economic losses to the breeding end of feed mills. The defects of the existing technology are as follows:

An audio alarm unit is provided on the control terminal 402 to prompt the staff. In this way, the products are transported through the feeding conveyor belt 100. The transported products are separated by the interval component and then transferred to the upper end of the transfer base 400 one by one. The products are subjected to quality inspection by the weight measuring unit and the temperature measuring unit. When the requirements are met, the sorting and conveying module will transfer the products to the first feeding chute 401, and the products will slide to the qualified product position. On the contrary, when they are unqualified, the sorting and conveying module will transfer the products to the second feeding chute 404, and the products will slide to the unqualified product position:

[0035] Here, the weight measuring unit is a weighing scale, which is arranged at the bottom of the transfer base 400. As long as the product is transferred to the transfer base 400, the weighing detection can be completed;

[0036] The temperature measuring unit is a thermal imager. The thermal imager includes a plurality of temperature measuring points, which are distributed in an array. The array distribution method can obtain the temperature around the product, obtain the data of each part, generate a thermal image, and perform warning processing when the comparison with the ambient temperature exceeds 5°C.

A steering transmission unit 300 is provided in cooperation with the position of each mounting hole. The lower end of the steering transmission unit 300 is connected to a steering mechanism for driving the change of its transmission direction. The transmission direction of the steering transmission unit 300 can be quickly adjusted through the steering mechanism, so as to achieve sorting and transmission;

[0038] The steering transmission unit 300 includes a rotating cylinder 301. An installation cavity 307 is provided at the upper end of the rotating cylinder 301. A plurality of transfer rollers 304 are rotatably provided at the upper port position of the installation cavity 307. A set of feeding wheels 305 are rotatably provided below the transfer rollers 304. A transmission belt 303 is drivingly connected between the two feeding wheels 305. A driving wheel 306 matching the transmission belt 303 is provided between the two feeding wheels 305. The driving wheel 306 is connected to a transfer motor 309 for driving it to rotate. The transfer motor 309 is installed on a motor bracket 308 in the installation cavity 307. Driven by the transfer motor 309, the transmission belt 303 rotates around the feeding wheels 305 and the driving wheel 306. A plurality of tension wheels 302 for tensioning the inner side of the transmission belt 303 are rotatably provided inside the installation cavity 307, so as to ensure that the transmission belt 303 is in close contact with the surface of the transfer rollers 304.

[0039] The steering mechanism includes a driven gear 314 fixedly connected to the bottom of the steering transmission unit 300. A horizontal push rod 315 is installed on one side of the transfer base 400 through a push frame. The output end of the horizontal push rod 315 is connected to a push frame 316. A plurality of guiding cross bars 312 are fixedly provided on the side surface of the push frame 316. A transmission rack 313 is provided on the surface of the guiding cross bar 312.

[0040] The spacer component includes a mounting bracket 202 erected above the feeding conveyor belt 100. A conversion motor 203 is fixedly provided at the central position of the mounting bracket 202. A turntable 204 is fixedly provided at the output end of the conversion motor 203. A plurality of material receiving grooves 201 matching the products are distributed on the outer side of the turntable 204. Arc-shaped guard plates 200 are symmetrically provided on both sides of the transmission path of the feeding conveyor belt 100. The two arc-shaped guard plates 200 match the outer sides of the material receiving grooves 201. A gap is left between the two arc-shaped guard plates 200 to facilitate the entry and discharge of the products. Two guiding inclined plates 205 for guiding the products are provided on the transmission bracket 101 upstream of the turntable 204. The two guiding inclined plates 205 are in a V-shaped structure, and the ends of the guiding inclined plates 205 are fixedly connected to the outer sides of the arc-shaped guard plates 200. In this way, the products stacked on the feeding conveyor belt 100 will be guided by the guiding inclined plates 205 and then smoothly enter the material receiving grooves 201. As the turntable 204 rotates, the products will slide along the inner walls of the arc-shaped guard plates 200 and then be transferred to the transfer base 400. This method can prevent multiple products from falling onto the transfer base 400 at the same time.

[0041] Working principle: During actual use, place the products at one end of the feeding conveyor belt 100. The two arc-shaped guard plates 200 match the outer sides of the material receiving grooves 201. A gap is left between the two arc-shaped guard plates 200 to facilitate the entry and discharge of the products. The products stacked on the feeding conveyor belt 100 will be guided by the guiding inclined plates 205 and then smoothly enter the material receiving grooves 201. As the turntable 204 rotates, the products will slide along the inner walls of the arc-shaped guard plates 200 and then be transferred to the transfer base 400. This method can prevent multiple products from falling onto the transfer base 400 at the same time. The products are inspected by the weighing unit and the temperature measuring unit. When the requirements are met, the sorting and conveying module will transfer the products to the first feeding chute 401, and the products will slide to the qualified product position. On the contrary, when they are unqualified, the sorting and conveying module will transfer the products to the second feeding chute 404, and the products will slide to the unqualified product position;

[0042] Embodiment 2

[0043] The difference from Embodiment 1 is that it further includes a calibration module and an image recognition module. The calibration module is used for the acquisition and analysis of the weighing verification data. After judgment, it is associated with the secondary production system. The core first level is associated with the packaging scale. The microscopic single-pack average net content of the data acquisition is fed back to the packaging scale, and the packaging scale system forms self-regulation to make the packaging net content tend to the set value;

[0044] The macroscopic net content of the whole batch (1 ton / batch) of data acquisition is judged and then fed back to the computer of the batching system in the central control room for manual fine-tuning. Solve the real-time adjustment of the single-pack weight and the data monitoring and adjustment of the product yield;

[0045] Image recognition module: recognize the overall image of the product packaging and label. If it is inconsistent with the input set image, it can be judged as abnormal. This is to solve the errors caused by the overall use of packaging, labels and content;

[0046] In the actual production process, the effective use of finished product weight data is of great significance to the improvement of feed production efficiency. The present invention realizes the automatic recording, aggregation and analysis of the real-time data of finished product weight through the following methods, thereby providing powerful guidance for enterprises to optimize production:

[0047] When the feed is produced and enters the weighing quality inspection link of the transmission terminal, the system will collect the weight data of each package of feed in real time. These data are transmitted to the data processing center at a very high frequency, and the center is equipped with a special data recording module. This module can accurately and stably record the weight information of each package of feed, including weight value, weighing time, batch and other detailed parameters, completely and accurately, forming a huge basic data set.

[0048] As production continues, the data aggregation module begins to play a role. It classifies and integrates the recorded data according to different dimensions. For example, it summarizes the daily, weekly, and monthly finished product weight data in chronological order; it aggregates all feed weight data of the same batch according to production batches. At the same time, statistical indicators of various types of data are calculated, such as mean, standard deviation, maximum, minimum, etc. Taking batch data as an example, by calculating the average weight of each batch of feed, we can intuitively understand the overall level of the weight of the batch of products; the standard deviation can reflect the degree of fluctuation of the weight of each package of feed in the batch. If the standard deviation is too large, it means that the weight stability of the batch of products is poor.

[0049] On the basis of data aggregation, the data analysis module uses advanced algorithms and models to conduct in-depth data mining. On the one hand, by comparing the weight data of finished products in different time periods and batches, the changing trend of weight data is analyzed. If the average weight of finished products in a certain stage shows a continuous downward trend, it may mean that there is a problem with the measurement accuracy of the packaging scale, or the material ratio in the production process has changed. At this time, the system will automatically feedback the analysis results to the relevant production department and equipment maintenance personnel. Equipment maintenance personnel can check and calibrate the packaging scale in time to ensure its measurement accuracy; the production department can further check the material ratio link and adjust the production process parameters to restore the weight of the subsequent feed production to normal.

[0050] On the other hand, the data analysis module will also conduct correlation analysis on the finished product weight data and other key data in the production process, such as the usage amount of raw materials, the operating parameters of production equipment, etc. By establishing a mathematical model, the internal relationship between the finished product weight and these factors is found. For example, it is analyzed that when the addition ratio of a certain raw material changes, the finished product weight will also fluctuate accordingly. Based on this, the enterprise can optimize the raw material ratio on the premise of ensuring product quality, reduce raw material waste while ensuring that the finished product weight meets the standard requirements, thereby improving the feed production efficiency and economic benefits.

[0051] In addition, the system also has a data visualization function, presenting the analysis results to enterprise management personnel and production operators in an intuitive and easy-to-understand chart form, such as line charts, bar charts, pie charts, etc. Management personnel can quickly understand the changes in the finished product weight during the production process through these charts, discover potential problems in a timely manner, and make scientific and reasonable decisions; production operators can, according to the information feedback by the charts, make real-time adjustments and optimizations to the production process, achieve refined management of the production process, and ultimately achieve the goal of improving the feed production efficiency.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
