Description

Technical Field

[0001] This utility model relates to a food packaging device, specifically a rapid packaging device for food processing. Background Technology

[0002] Puffed stick foods, a type of puffed food, are mainly made from grains, potatoes, or beans, processed through puffing processes such as baking, frying, microwaving, or extrusion, and are fixed in a stick shape. In the production process, the packaging stage is crucial for these foods. Existing packaging equipment typically uses mechanical grippers to hold the food and place it into a packaging box, but this method is inefficient and unsuitable for large-scale production.

[0003] Chinese patent CN202295400U discloses a feeding mechanism for packaging stick-shaped food products. This mechanism includes a control system, a conveying trough corresponding to the material, and a material sorting mechanism located above the conveying trough. Specifically, the material sorting mechanism consists of a material arranging cavity with a length and width corresponding to the stick-shaped food product, and a discharging mechanism located above the material arranging cavity. A pushing mechanism is located below the material arranging cavity. The working principle of this patent is as follows: the discharging mechanism neatly feeds the stick-shaped food products into the material arranging cavity, where the food accumulates from top to bottom. Subsequently, the control system controls the pushing mechanism to move back and forth, causing the material to fall one stick at a time and be pushed into the conveying trough, ultimately falling into the packaging box.

[0004] Although the existing technology achieves the sorting and pushing of food through the discharge and push mechanisms, the food surface is easily worn due to friction during the movement of the food through the conveyor trough, resulting in food residue and potentially causing blockage of the conveyor trough. Utility Model Content

[0005] The purpose of this invention is to provide a rapid packaging device for food processing. It features a material bin with a rotating feeding wheel inside. The feeding wheel has several feeding troughs. When food falls into the troughs, the feeding wheel rotates, feeding the food one by one into the packaging box. The rotation of the feeding wheel achieves automatic feeding and arrangement of the food, avoiding the food wear and conveyor trough blockage problems caused by friction in traditional pushing methods. Furthermore, because the feeding wheel can rotate continuously and stably, the feeding speed is significantly improved, making the entire packaging process more efficient.

[0006] To address the problems of existing technologies, this utility model provides a rapid packaging device for food processing, including a conveying device, a feeding device installed on top of the conveying device, and a capping assembly installed at the discharge end of the conveying device. The feeding device includes a material box for storing stick-shaped food items. Inside the material box, a feeding wheel is rotatably arranged for discharging the stick-shaped food items one by one. Several material slots for storing stick-shaped food items are evenly distributed on the feeding wheel. A first rotary drive component for rotating the feeding wheel is also fixed on one side of the material box. A connecting shaft is arranged at the center of the feeding wheel. The output end of the first rotary drive component is connected to the connecting shaft on the feeding wheel. The feeding device also includes a detection device for detecting the number of rotations of the feeding wheel.

[0007] Preferably, the detection device includes a first laser emitter fixed on a connecting shaft on the feed wheel and a first photoelectric sensor installed on one side of the material box, wherein the light emitted by the first laser emitter is received by the first photoelectric sensor.

[0008] Preferably, the material trough is an arc-shaped trough.

[0009] Preferably, the bottom of the material box is also provided with a feeding port for dispensing stick-shaped food.

[0010] Preferably, the feeding device includes a second laser emitter installed on one side of the bottom of the material box, and the feeding device also includes a second photoelectric sensor installed on the other side of the bottom of the material box, and the light emitted by the second laser emitter is received by the second photoelectric sensor.

[0011] Preferably, the bottom of the conveying device near the unloading device is provided with a positioning device for positioning the packaging box. The positioning device includes positioning components symmetrically distributed on both sides of the conveying device. The positioning components include a slide rod slidably disposed on the conveying device. One end of the slide rod is connected to a positioning plate, and the other end of the slide rod is connected to a connecting plate. The cross-section of the connecting plate is "L" shaped.

[0012] Preferably, the positioning device further includes a synchronization component for synchronizing the movement of the two positioning plates. The synchronization component includes a bracket fixed on the conveying device, a second rotary drive component fixed at the center of the top of the bracket, a first transmission rod connected at the center of the first transmission rod to the output end of the second rotary drive component, and a second transmission rod, one end of the second transmission rod being movably connected to the connecting plate, and the other end of the second transmission rod being movably connected to one end of the first transmission rod.

[0013] Preferably, the cover assembly includes a first moving mechanism and a moving plate. The first moving mechanism is used to drive the moving plate to move laterally back and forth. A second moving mechanism is fixed on the moving plate. The output end of the second moving mechanism passes through the moving plate and is connected to a suction cup assembly for adsorbing the cover.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. This application features a material box with a rotating material trough inside. When the stick-shaped food falls into the trough, the first rotating drive causes the feeding wheel to rotate, thereby conveying the stick-shaped food into the packaging box one by one. This packaging method has a simple structure, and the food is less likely to clog the packaging device. At the same time, the feeding speed is fast.

[0016] 2. This application also includes a positioning device. During the conveying process of the packaging box, it may deviate due to various reasons, resulting in inaccurate alignment with the feeding port. Therefore, when the packaging box is conveyed to the bottom of the feeding port, the two positioning plates are driven to move relative to each other through a synchronization component, precisely constraining the packaging box to the center position of the conveying device, thereby achieving accurate positioning of the packaging box and effectively avoiding the problem of stick-shaped food failing to fall into the packaging box due to packaging box deviation.

[0017] 3. This application achieves automatic sealing of packaging boxes by incorporating a capping assembly. The suction cup component within the capping assembly is responsible for adsorbing the lid. Through the coordinated action of a first moving mechanism and a second moving mechanism, the lid is transferred from its storage position to the top of the packaging box. Subsequently, the second moving mechanism continues to press down, tightly pressing the lid against the packaging box to complete the sealing process. This design not only improves packaging efficiency but also ensures the airtightness and aesthetics of the packaging box. Attached Figure Description

[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] Reference Figures 1-8 As shown, this utility model provides a rapid packaging device for food processing, including a conveying device 1, a feeding device 11 installed on top of the conveying device 1, and a capping assembly 13 installed at the discharge end of the conveying device 1. The feeding device 11 includes a material box 111 for storing stick-shaped food items. The material box 111 is a container for storing stick-shaped food items to be packaged. Its design should be able to hold a certain number of food items while keeping the stick-shaped food items neatly arranged for easy feeding. Inside the material box 111, a feeding wheel 112 is rotatably arranged for feeding the stick-shaped food items one by one. Several material slots 1121 for storing stick-shaped food items are evenly distributed on the feeding wheel 112, and each material slot 1121 is used to temporarily store one stick-shaped food item. When the feeding wheel 112 rotates, each material slot 1121 passes through the feeding position in sequence, releasing the food items one by one onto the packaging box. A first rotary drive 113 for rotating the feed wheel 112 is fixed on one side of the material box 111. A connecting shaft is provided at the center of the feed wheel 112. The output end of the first rotary drive 113 is connected to the connecting shaft on the feed wheel 112. The feed device 11 also includes a detection device for detecting the number of rotations of the feed wheel 112.

[0029] refer to Figure 3 and Figure 4As shown, the detection device includes a first laser emitter 114 fixed on a connecting shaft on the feeding wheel 112 and a first photoelectric sensor 115 mounted on one side of the material bin 111. The light emitted by the first laser emitter 114 is received by the first photoelectric sensor 115. The material trough 1121 is an arc-shaped groove. The bottom of the material bin 111 is also provided with a feeding port 1111 for feeding rod-shaped food. The first laser emitter 114 emits a beam of light, usually a laser beam, which travels along a fixed path towards the first photoelectric sensor 115. When the feeding wheel 112 rotates once, the photoelectric sensor can receive an interrupt signal. By counting the number of these interrupt signals, the system can accurately know how many revolutions the feeding wheel 112 has made, thereby determining the quantity of food that has been fed.

[0030] When the stick-shaped food falls into the trough 1121, the first rotating drive 113 causes the feeding wheel 112 to rotate, thereby conveying the stick-shaped food into the packaging box one by one. This packaging method has a simple structure, and the food is less likely to clog the packaging device, while the feeding speed is fast.

[0031] The feeding device 11 includes a second laser emitter 14 installed on one side of the bottom of the material box 111, and the feeding device 11 also includes a second photoelectric sensor 15 installed on the other side of the bottom of the material box 111. The light emitted by the second laser emitter 14 is received by the second photoelectric sensor 15.

[0032] The second laser emitter 14 emits a beam of light, which is received by the second photoelectric sensor 15. When the stick-shaped food falls, the light is blocked. The second photoelectric sensor 15 can detect this change and generate a signal. By counting the number of these interruption signals, the number of food items that have fallen can be determined.

[0033] refer to Figure 4-7 As shown, a positioning device 12 for positioning the packaging box is provided at the bottom of the conveying device 1 near the unloading device 11. The positioning device 12 includes positioning components 122 symmetrically distributed on both sides of the conveying device 1. The positioning components 122 include a slide rod 1223 slidably disposed on the conveying device 1. One end of the slide rod 1223 is connected to a positioning plate 1221, and the other end of the slide rod 1223 is connected to a connecting plate 1222. The cross-section of the connecting plate 1222 is "L" shaped.

[0034] The positioning device 12 also includes a synchronization component 121 for synchronizing the movement of the two positioning plates 1221. The synchronization component 121 includes a bracket 1214 fixed on the conveying device 1. A second rotary drive member 1211 is fixed at the center of the top of the bracket 1214. The synchronization component 121 includes a first transmission rod 1212. The center of the first transmission rod 1212 is connected to the output end of the second rotary drive member 1211. The synchronization component 121 includes a second transmission rod 1213. One end of the second transmission rod 1213 is movably connected to the connecting plate 1222, and the other end of the second transmission rod 1213 is movably connected to one end of the first transmission rod 1212.

[0035] When the packaging box is conveyed to the bottom of the feeding port 1111, the two positioning plates 1221 are driven to move relative to each other by the synchronization component 121, so as to accurately constrain the packaging box to the center position of the conveying device 1, thereby achieving accurate positioning of the packaging box and effectively avoiding the problem that the stick-shaped food cannot fall into the packaging box due to the offset of the packaging box.

[0036] refer to Figure 8 As shown, the cover assembly 13 includes a first moving mechanism 131 and a moving plate 132. The first moving mechanism 131 is used to drive the moving plate 132 to move laterally and reciprocally. A second moving mechanism 133 is fixed on the moving plate 132. The output end of the second moving mechanism 133 passes through the moving plate 132 and is connected to a suction cup assembly 134 for adsorbing the cover.

[0037] The primary function of the first moving mechanism 131 is to drive the moving plate 132 to move laterally reciprocally. This movement is an indispensable step in the capping process, allowing the suction cup assembly 134 to move to different positions in the horizontal direction to pick up and place the lid. The first moving mechanism 131 may employ a motor and lead screw combination, a cylinder, or a hydraulic cylinder as its driving method. These driving methods provide stable and controllable moving force, ensuring that the moving plate 132 can move accurately in the horizontal direction. The primary function of the second moving mechanism 133 is to drive the suction cup assembly 134 to move vertically. This movement is a crucial step in the capping process because it allows the suction cup assembly 134 to accurately pick up the lid and place it on the packaging box. The second moving mechanism 133 may also employ a motor and lead screw combination, a cylinder, or a hydraulic cylinder as its driving method. These driving methods provide stable and controllable vertical moving force. The suction cup assembly 134 is the end effector of the capping assembly 13, responsible for adsorbing and releasing the lid. The suction cup assembly 134 typically includes one or more suction cups that attract the lid by negative or positive pressure and release it when needed.

[0038] The suction cup assembly 134 in the capping assembly 13 is responsible for adsorbing the lid. Through the coordinated action of the first moving mechanism 131 and the second moving mechanism 133, the lid is transferred from the storage position to the top of the packaging box. Subsequently, the second moving mechanism 133 continues to press down, tightly pressing the lid against the packaging box, completing the sealing process. This design not only improves packaging efficiency but also ensures the airtightness and aesthetics of the packaging box.

[0039] Working Principle: During operation, the operator first places the stick-shaped food item to be packaged into the material bin 111. Simultaneously, the packaging box is continuously conveyed to the bottom position of the discharge port 1111 via the conveying device 1. At this point, by activating the second rotary drive 1211, the second rotary drive 1211 drives the first transmission rod 1212 to rotate. The rotation of the first transmission rod 1212 further drives the second transmission rod 1213 to move, causing the connecting plate 1222 to move. The movement of the two connecting plates 1222 drives the sliding rod 1223 to move, allowing the two positioning plates 1221 to move relative to each other and precisely constrain the packaging box to the center position of the conveying device 1, ensuring accurate positioning of the packaging box. After the packaging box is positioned, by activating the first rotary drive 113, the first rotary drive 113 causes the discharge wheel 112 to rotate. As the feeding roller 112 rotates, the feeding trough 1121 on the feeding roller 112 carries the stick-shaped food items one by one to the feeding port 1111, and smoothly drops the food items into the positioned packaging box. This process achieves fast and accurate packaging of stick-shaped food items. As the packaging box continues to move along the conveyor 1, the capping assembly 13 begins to perform the capping operation. First, the suction cup assembly 134 adheres to the lid to be used. Then, under the combined action of the first moving mechanism 131 and the second moving mechanism 133, the lid is smoothly transferred to the top of the packaging box. Finally, through the further pressing action of the second moving mechanism 133, the lid is tightly pressed onto the packaging box, thus completing the entire packaging process. In summary, this device, through a series of precise mechanical linkages and automated control, achieves fast, accurate, and efficient packaging of stick-shaped food items.

[0040] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
