Description

Technical Field

[0001] This invention relates to the field of food packaging paper technology, and more specifically, to a system and process for conveying, hot stamping, and automatic identification and sorting of food packaging paper. Background Technology

[0002] Food packaging paper refers to paper materials specifically used for food packaging. It not only needs to have good printability to present exquisite patterns and text, but also needs to meet food safety standards to ensure that it will not contaminate food or harm human health. In the food packaging industry, there are many types of food packaging paper. According to different food characteristics and packaging needs, it can be divided into ordinary food packaging paper, oil-proof food packaging paper, waterproof food packaging paper, etc. These different types of food packaging paper differ in materials, performance and manufacturing processes, but they all play an important role in protecting food, facilitating transportation and promoting sales.

[0003] According to patent document CN119076295A, a waxing and flexible continuous winding system and manufacturing method for food packaging paper are disclosed. The system includes a frame and a winding mechanism, with an unwinding assembly and auxiliary rollers mounted on the frame. A flat plate is fixedly connected between the left and right sides of the frame's inner wall, and a main waxing mechanism and an edge waxing mechanism are mounted above the flat plate. The main waxing mechanism consists of a wax storage tank, a main waxing roller, and a main scraper assembly. The main waxing mechanism and the edge waxing mechanism work together to complete the waxing process on the food packaging paper. The edge waxing mechanism includes an edge waxing component. This invention relates to the field of food packaging paper production technology. This waxing and flexible continuous winding system and manufacturing method for food packaging paper uses the edge waxing component to draw wax from the wax storage tank and apply it separately to the edges of the food packaging paper, thus avoiding the problem of unsatisfactory edge waxing results due to gravity distribution factors and the large size of the food packaging paper.

[0004] In the production of food packaging paper, hot stamping is an indispensable and crucial step. However, traditional packaging paper processing equipment may have a significant limitation: it cannot automate the identification and screening of defective packaging paper. This means that the production line usually relies on manual inspection of each sheet of packaging paper to determine whether it meets quality standards. This manual inspection method is not only inefficient, but also prone to missed or incorrect inspections due to worker fatigue or distraction during long-term continuous operation. If defective packaging paper is not removed in time, it may enter the subsequent hot stamping process along with qualified packaging paper, resulting in defective and good products being mixed together for hot stamping. This situation not only directly affects the overall appearance and functionality of the packaging paper, but may also further reduce the quality of the final product, affecting brand reputation and customer satisfaction. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a feeding, hot stamping, automatic identification, and screening system and process for food packaging paper. The technical problem this invention aims to solve is that the identification and screening of defective packaging paper cannot be automated. This necessitates manual inspection of each sheet of packaging paper on the production line to determine whether it meets quality standards. This manual inspection method is not only inefficient, but also prone to missed or incorrect inspections due to worker fatigue or distraction during long-term continuous operation. If defective packaging paper is not removed in time, it may enter the subsequent hot stamping process along with qualified packaging paper, resulting in defective and good products being mixed together for hot stamping.

The outer ends of the two rear columnar rotating blocks extend to the outer sides of the two concave side plates and are fixedly connected to rotating blocks.

[0014] As a further aspect of the present invention: the bottom of the two sets of connecting blocks on the front side are fixedly connected to an imprinting top plate, and the bottom of the two imprinting top plates are fixedly connected to an imprinting bottom plate.

[0015] In addition, this invention relates to a feeding, hot stamping, and automatic identification and sorting system and process for food packaging paper, including the following steps: Step 1: Place the food packaging paper on the initial conveyor plate, start the conveyor device, and smoothly convey the packaging paper to the bottom working area of ​​the picking component. During this process, the conveyor device maintains a constant and stable speed to ensure that the packaging paper is in the correct position, laying the foundation for subsequent picking operations. Step 2: Take the lifting electric push rod from the component and start it. Push the lifting plate to slide down along the vertical guide rod. As the lifting plate descends, the adsorption plate gradually approaches the packaging paper. When the adsorption plate reaches the appropriate position, the adsorption control element is immediately activated, so that the adsorption block generates a strong adsorption force, tightly adsorbing the packaging paper to the bottom of the adsorption plate. At the same time, the defect detection camera is turned on to perform a comprehensive and detailed scan and inspection of the surface of the packaging paper. If a defect is detected, the system will quickly record the defect location information to provide an accurate basis for subsequent screening and processing. Step 3: The short-distance push-pull electric push rod is activated, pushing the sliding plate to slide along the second horizontal guide rod. During the sliding process, the position of the suction head connected to the upright plate is adjusted accordingly to ensure that the packaging paper can be accurately placed in the position required for the subsequent process. After the position adjustment is completed, the electric push rod is activated, and the entire picking component is moved along the guide rod through the picking component push-pull block, transporting the picking component with the packaging paper to the second conveyor plate and the defective part conveyor plate. Step 4: Screening is carried out based on the defect detection results. If the packaging paper is defective, the adsorption plate is pushed to the top of the defective part conveyor plate by the lifting electric push rod. Then, the defective packaging paper is transported to the outside of the device through the defective part conveyor plate for centralized processing. If the packaging paper is not defective, the taking component controls the packaging paper to fall to the top of the second conveyor plate, which then transports it to the hot stamping mechanism. Step 5: When the packaging paper reaches the position of the hot stamping mechanism, the lifting electric push rod is activated again, pushing the lifting plate down to accurately place the packaging paper under the hot stamping suction head. At this time, the hot stamping mechanism electric push rod is activated, pushing the vertical sliding rod to slide along the vertical sliding rod guide plate. The vertical sliding rod drives the rotating block to rotate through the columnar push-pull rod. The rotating block drives the columnar rotating block to rotate, and the gear on the columnar rotating block rotates accordingly. Through a series of precision transmissions, the rotating vertical plate, rotating horizontal plate and other components move in tandem, ultimately driving the hot stamping suction head to move downward to perform the hot stamping operation on the packaging paper. During the hot stamping process, the small electric vertical push rod can flexibly adjust the height of the rectangular top lifting plate according to actual needs, thereby precisely adjusting the pressure of the hot stamping suction head to ensure the best hot stamping effect. Step Six: After hot stamping is completed, all parts of the hot stamping mechanism quickly reset and are conveyed to the next process by the second conveyor plate. This completes the entire process of feeding, hot stamping, and automatic identification and screening of food packaging paper.

[0016] The beneficial effects of this invention are as follows: This invention, by incorporating a conveying and supplying mechanism, a central connecting rod, and a hot stamping mechanism, achieves an integrated and automated operation process for food packaging paper, from supply to hot stamping and then to automatic identification and screening. Throughout the process, precise mechanical control and an intelligent detection system not only significantly improve production efficiency and reduce manual intervention but also substantially enhance the accuracy of product quality control. The design of this invention cleverly integrates mechanical transmission, electric control, and image recognition technologies, ensuring the accuracy and stability of each step of the operation and providing an efficient and reliable solution for the food packaging industry.

Each of the two stamping top plates 315 has a fixedly connected stamping bottom plate 316 at its bottom. When food packaging paper needs to be supplied, hot stamped, and automatically identified and screened, the entire process begins with the conveying of the packaging paper. The operator places the packaging paper to be processed on two conveyor plates 1110. The two conveyor plates work together to smoothly convey the packaging paper to the bottom of the picking component 12. Then, the system automatically starts the lifting electric push rod 124, which pushes the lifting plate 128 to slide smoothly down along the vertical guide rail 126, thereby driving the adsorption plate 1214 to gradually approach the packaging paper below. Once the adsorption plate 1214 reaches the preset suitable position, the adsorption control element 127 is immediately activated, causing the adsorption block 1215 to generate a strong adsorption force, firmly and evenly adsorbing the packaging paper onto the bottom surface of the adsorption plate 1214. At the same time, the defect detection camera 1216 integrated on the picking component starts working at high speed to perform a comprehensive scan and fine inspection of the surface of the packaging paper. If any defect is found, the system will record the type of defect and its accurate location information in real time, providing data support for subsequent sorting. Next, the short-distance push-pull electric push rod 129 is activated, pushing the sliding plate 1212 to slide horizontally along the second horizontal guide rod 1210 to fine-tune the position of the suction head connected to the upright plate 1213, ensuring that the packaging paper can be accurately placed in the designated position required by the subsequent process. After the position adjustment is completed, the electric push rod 115 starts to work, driving the entire picking assembly 12 to move along the guide rod 116 through the picking part push-pull block 123, transporting the picking assembly with the adsorbed packaging paper to the area of ​​the second conveyor plate 1111 and the defective part conveyor plate 1112; In this stage, the system automatically sorts the packaging paper based on the defect detection results: if the packaging paper is found to be defective, the adsorption plate 1214 will be pushed down to the top of the defective part conveyor plate 1112 by the lifting electric push rod 124, and the defective product will be conveyed out of the device through the conveyor plate; if the packaging paper is intact and without defects, it will be placed smoothly on the second conveyor plate 1111 by the control of the picking component, and conveyed to the hot stamping mechanism 3 for the next step of processing. When the packaging paper reaches the station of the hot stamping mechanism 3, the lifting electric push rod 124 is activated again, pushing the lifting plate 128 down to accurately place the packaging paper under the hot stamping suction head 311 to receive hot stamping. At this time, the hot stamping mechanism electric push rod 33 starts to run, pushing the vertical sliding rod 318 to slide down along the vertical sliding rod guide plate 3111. The vertical sliding rod 318 drives the rotating block 317 to rotate through the columnar push-pull rod 319. The rotating block 317 further drives the columnar rotating block 32 to rotate. The gear 38 on the columnar rotating block 32 moves accordingly. Through a series of precision transmissions, the rotating vertical plate 35, rotating horizontal plate 36 and other components work together to drive the hot stamping suction head 311 to move down and perform hot stamping operation on the packaging paper. During the hot stamping process, the small electric vertical push rod 313 can adjust the height of the rectangular top lifting plate 314 in real time according to the process requirements, thereby precisely controlling the pressure of the hot stamping suction head 311 to ensure that the hot stamping pattern is clear, uniform and meets the quality requirements. After the hot stamping is completed, the components of the hot stamping mechanism are automatically reset and conveyed to the next process through the second conveyor plate 1111. The whole process realizes the efficient and automated operation of food packaging paper from conveying and supplying, hot stamping processing to automatic identification and screening.

[0022] In addition, this invention relates to a feeding, hot stamping, and automatic identification and sorting system and process for food packaging paper, including the following steps: Step 1: Place the food packaging paper on the initial conveyor plate 1110, start the conveyor device, and smoothly convey the packaging paper to the bottom working area of ​​the picking component 12. During this process, the conveyor device maintains a uniform and stable operation to ensure that the packaging paper is in the correct position, laying the foundation for subsequent picking operations. Step 2: Take the lifting electric push rod 124 in component 12 and start it. Push the lifting plate 128 to slide down along the vertical guide rod 126. As the lifting plate 128 descends, the adsorption plate 1214 gradually approaches the packaging paper. When the adsorption plate 1214 reaches the appropriate position, the adsorption control element 127 is immediately activated, so that the adsorption block 1215 generates a strong adsorption force, which firmly adsorbs the packaging paper to the bottom of the adsorption plate 1214. At the same time, the defect detection camera 1216 is turned on to perform a comprehensive and detailed scan and inspection of the surface of the packaging paper. If a defect is detected, the system will quickly record the defect location information to provide an accurate basis for subsequent screening and processing. Step 3: The short-distance push-pull electric push rod 129 is started, pushing the sliding plate 1212 to slide along the second horizontal guide rod 1210. During the sliding process, the position of the suction head connected to the upright plate 1213 is adjusted accordingly to ensure that the packaging paper can be accurately placed in the position required by the subsequent process. After the position adjustment is completed, the electric push rod 115 is started, and the entire picking component 12 is moved along the guide rod 116 through the picking component push-pull block 123, transporting the picking component 12 with the packaging paper adsorbed to the second conveyor plate 1111 and the defective part conveyor plate 1112. Step 4: Screening is carried out based on the defect detection results. If the packaging paper is defective, the adsorption plate 1214 is pushed to the top of the defective part conveying plate 1112 under the push of the lifting electric push rod 124. Then, the defective packaging paper is transported to the outside of the device through the defective part conveying plate 1112 for centralized processing. If the packaging paper is not defective, the picking component 12 controls the packaging paper to fall to the top of the second conveying plate 1111, and the second conveying plate 1111 transports it to the hot stamping mechanism 3. Step 5: When the packaging paper reaches the position of the hot stamping mechanism 3, the lifting electric push rod 124 is activated again, pushing the lifting plate 128 down to accurately place the packaging paper under the hot stamping suction head 311. At this time, the hot stamping mechanism electric push rod 33 is activated, pushing the vertical sliding rod 318 to slide along the vertical sliding rod guide plate 3111. The vertical sliding rod 318 drives the rotating block 317 to rotate through the columnar push-pull rod 319. The rotating block 317 drives the columnar rotating block 32 to rotate, and the gear 38 on the columnar rotating block 32 rotates accordingly. Through a series of precision transmissions, the rotating vertical plate 35, rotating horizontal plate 36 and other components move in tandem, ultimately driving the hot stamping suction head 311 to move downward to perform the hot stamping operation on the packaging paper. During the hot stamping process, the small electric vertical push rod 313 can flexibly adjust the height of the rectangular top lifting plate 314 according to actual needs, thereby precisely adjusting the pressure of the hot stamping suction head 311 to ensure the best hot stamping effect. Step Six: After hot stamping is completed, all parts of the hot stamping mechanism quickly reset and are conveyed to the next process by the second conveyor plate 1111. This completes the entire process of feeding, hot stamping, and automatic identification and screening of food packaging paper.

[0023] The working principle of this invention is as follows: When food packaging paper needs to be supplied, hot-stamped, and automatically identified and screened, the packaging paper is first placed on two conveyor plates 1110 and then conveyed to the bottom of the picking component 12. Then, the lifting electric push rod 124 is activated to push the lifting plate 128 downwards along the vertical guide rail 126, bringing the adsorption plate 1214 close to the packaging paper. When the adsorption plate 1214 reaches the appropriate position, the adsorption control element 127 is activated, causing the adsorption block 1215 to generate adsorption force, tightly adsorbing the packaging paper onto the bottom of the adsorption plate 1214. Simultaneously, the defect detection camera 1216 starts working, scanning and detecting the surface of the packaging paper. If a defect is found, its location is recorded. Information, then, the short-distance push-pull electric push rod 129 is activated, pushing the sliding plate 1212 to slide along the second horizontal guide rod 1210, adjusting the position of the suction head connecting the upright plate 1213 to ensure that the packaging paper can be accurately placed in the position required for subsequent processes. After the position adjustment is completed, the electric push rod 115 is activated, driving the entire picking assembly 12 to move along the guide rod 116 through the picking part push-pull block 123, transporting the picking assembly 12 with the packaging paper adsorbed to the second conveyor plate 1111 and the defective part conveyor plate 1112. If the packaging paper is defective, the suction plate 1214 is pushed to the top of the defective part conveyor plate 1112 by the lifting electric push rod 124, and then through the defective part conveyor plate 1112. 112. Defective packaging paper is conveyed outside the device, while undefective packaging paper is controlled by the picking component 12 to fall onto the top of the second conveyor plate 1111 and conveyed to the hot stamping mechanism 3. When it reaches the hot stamping mechanism 3, the lifting electric push rod 124 is activated again, pushing the lifting plate 128 down to place the packaging paper below the hot stamping suction head 311. At this time, the hot stamping mechanism electric push rod 33 is activated, pushing the vertical sliding rod 318 to slide along the vertical sliding rod guide plate 3111. The vertical sliding rod 318 drives the rotating block 317 to rotate through the columnar push-pull rod 319. The rotating block 317 drives the columnar rotating block 32 to rotate, and the gear 38 on the columnar rotating block 32 rotates accordingly. Through a series of transmissions, the rotating plate is rotated. 35. The rotating horizontal plate 36 and other components move in tandem, ultimately driving the hot stamping suction head 311 downward to perform hot stamping on the packaging paper. During the hot stamping process, the small electric vertical push rod 313 can adjust the height of the rectangular top lifting plate 314 as needed, thereby adjusting the pressure of the hot stamping suction head 311 to ensure the hot stamping effect. After the hot stamping is completed, all components of the hot stamping mechanism are reset, and the pick-up component 12 is restarted to pick up the hot stamped packaging paper. According to the defect information recorded by the defect detection camera 1216, if the packaging paper is defect-free, it is placed on the second conveyor plate 1111 and conveyed to the next process, thereby realizing the entire process of food packaging paper conveying, hot stamping, and automatic identification and screening.
