Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to a food packaging device. Background Technology

[0002] Food packaging refers to the process of wrapping food with appropriate materials, containers, and techniques to prevent it from being adversely affected by physical, chemical, or biological factors during production, processing, transportation, storage, and sales, while also meeting consumers' needs for food safety, hygiene, convenience, and aesthetics.

[0003] Current food packaging equipment is typically semi-automated, requiring operators to be distributed throughout the production line to coordinate with corresponding processes. Common pre-packaging steps involve operators manually stacking food containers, such as bags and cans, on the line and manually opening them. Filling equipment, such as robotic arms, then feeds the food into these containers. Finally, workers at the end of the line collect the filled food to complete the packaging. This process is labor-intensive, and the speed at which food containers are manually stacked in the pre-packaging stage determines the efficiency of subsequent packaging, thus limiting the overall efficiency of the production line and reducing overall food packaging efficiency. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a food packaging equipment that addresses the problem that current food packaging equipment is usually semi-automatic, and the speed at which food packaging containers are manually stacked in the semi-automatic design determines the subsequent food packaging efficiency, thus preventing a significant improvement in current food packaging efficiency.

[0005] This utility model provides a food packaging device, including a fixed frame, a sliding component slidably disposed on the fixed frame, a bag opening component movably disposed on the sliding component for opening the food packaging bag, a bag dispensing component disposed near the bag opening component and opposite to it, and a conveyor belt assembly disposed at the bottom of the fixed frame and horizontally disposed relative to the discharge port of the bag dispensing component.

[0006] The conveyor belt assembly includes a packaging bag conveyor belt disposed near the bag dispensing assembly, a shipping conveyor belt disposed on the side of the packaging bag conveyor belt away from the bag dispensing assembly, and a food conveyor belt disposed on the side of the packaging bag conveyor belt away from the shipping conveyor belt and opposite to it, wherein a pushing assembly is disposed on the food conveyor belt.

[0007] Specifically, the food from the food conveyor belt is pushed sequentially into the packaging bags on the packaging bag conveyor belt by the pushing component and then exported to the delivery conveyor belt.

[0008] As described above, the design of the bag opening component located at the discharge port of the bag dispensing component allows for direct opening of the exported packaging bag. After each bag opening, the bag opening component retracts along the original path. During the second bag opening operation, as the bag opening component moves towards the bag dispensing component, the bag dispensing component simultaneously performs the bag dispensing operation and, after docking, directly performs the bag opening operation, saving process time and improving continuity. At the same time, the pushing component pushes the food from the food conveyor belt into the packaging bags on the packaging bag conveyor belt and out to the shipping conveyor belt, further demonstrating the continuity of the equipment. The overall workflow of the equipment adopts a fully automated design, which greatly avoids food contamination caused by frequent contact between operators and food. It also solves the problem that current food packaging equipment is usually semi-automated, and the speed of manual stacking of food packaging containers in semi-automated designs determines the subsequent food packaging efficiency, thus preventing a significant improvement in current food packaging efficiency.

[0009] In addition, the food packaging equipment proposed according to the embodiments of this utility model may also have the following additional technical features:

[0010] Furthermore, the food packaging equipment also includes a heat dissipation fan box fitted onto the outer surface of the fixed frame.

[0011] Furthermore, the sliding assembly includes at least two first drive motors disposed at the bottom of the fixed frame, a first screw movably disposed at the bottom of the fixed frame and connected to the output end of the first drive motor, a sliding frame sleeved on the first screw and sliding along its trajectory, and a second screw movably disposed at the top of the sliding frame.

[0012] Furthermore, the bag opening assembly includes a sliding rod sleeved on the second screw and sliding along its trajectory, a fixed frame disposed on the side of the sliding rod away from the second screw, at least two second drive motors disposed on the top of the fixed frame, a third screw movably embedded in the fixed frame and connected to the output end of the second drive motor, a sliding plate sleeved on the third screw, and a fixed plate fixedly connected to the bottom of the fixed frame and disposed parallel to the sliding plate.

[0013] Furthermore, the bag dispensing assembly includes a fixed platform, bag clamping members disposed on both sides of the top of the fixed platform, and a feeding roller disposed between the two bag clamping members.

[0014] Furthermore, the packaging bag clamping component includes a driving component fixedly mounted on the top of the fixed platform, a push rod mounted on the output end of the driving component, and a push plate mounted on the side of the push rod away from the driving component.

[0015] Furthermore, the feeding assembly includes a third drive motor disposed on the side of the food conveyor belt away from the packaging bag conveyor belt, a fourth screw drively connected to the third drive motor, and a feeding hopper disposed on the side of the fourth screw closer to the food conveyor belt.

[0028] Please see Figures 1 to 6 The image shows a food packaging device according to an embodiment of the present invention, including a fixed frame 2, a sliding component slidably disposed on the fixed frame 2, a bag opening component 7 movably disposed on the sliding component for opening food packaging bags, a bag dispensing component 8 disposed near the bag opening component 7 and opposite to it, and a conveyor belt assembly disposed at the bottom of the fixed frame 2 and horizontally disposed relative to the discharge port of the bag dispensing component 8. The conveyor belt assembly includes a packaging bag conveyor belt 9 disposed near the bag dispensing component 8, a delivery conveyor belt 10 disposed on the side of the packaging bag conveyor belt 9 away from the bag dispensing component 8, and a food conveyor belt 11 disposed on the side of the packaging bag conveyor belt 9 away from the delivery conveyor belt 10 and opposite to it. A pushing component 12 is provided on the food conveyor belt 11, wherein the food on the food conveyor belt 11 is pushed sequentially into the packaging bags on the packaging bag conveyor belt 9 by the pushing component 12 and discharged to the delivery conveyor belt 10.

[0029] Furthermore, the food packaging equipment also includes a heat dissipation box 1 sleeved on the outer surface of the fixed frame 2. The sliding assembly includes at least two first drive motors 3 disposed at the bottom of the fixed frame 2, a first screw 4 movably disposed at the bottom of the fixed frame 2 and connected to the output end of the first drive motor 3, a sliding frame 5 sleeved on the first screw 4 and sliding along its trajectory, and a second screw 6 movably disposed on the top of the sliding frame 5. The bag opening assembly 7 includes a sliding rod 71 sleeved on the second screw 6 and sliding along its trajectory, a fixed frame 72 disposed on the side of the sliding rod 71 away from the second screw 6, at least two second drive motors 73 disposed on the top of the fixed frame 72, a third screw 74 movably embedded in the fixed frame 72 and connected to the output end of the second drive motor 73, and a sliding rod 74 sleeved on the third screw 74. The moving plate 75 and the fixed plate 76 fixedly connected to the bottom of the fixed frame 72 and arranged parallel to the sliding plate 75 are included. The bag dispensing assembly 8 includes a fixed platform 81, packaging bag clamping members arranged on both sides of the top of the fixed platform 81, and feeding rollers 85 arranged between the two packaging bag clamping members. The packaging bag clamping members include a driving member 82 fixedly arranged on the top of the fixed platform 81, a push rod 83 arranged at the output end of the driving member 82, and a push plate 84 arranged on the side of the push rod 83 away from the driving member 82. The feeding assembly 12 includes a third drive motor 121 arranged on the side of the food conveyor belt 11 away from the packaging bag conveyor belt 9, a fourth screw 122 that is drivenly connected to the third drive motor 121, and a feeding hopper 123 arranged on the side of the fourth screw 122 that is close to the food conveyor belt 11.

[0030] It should be noted that a controller is installed at any convenient location for the operator on the food packaging equipment. The controller can be an MCU (Microcontroller Unit) chip to control the food packaging equipment. The controller and the food packaging equipment are electrically connected, which can include wired and wireless connections. Wireless connection methods include, but are not limited to, Bluetooth, WiFi, IF radio frequency, and Zigbee. Wired connection methods include, but are not limited to, a USB cable that connects the food packaging equipment and the controller.

[0031] In practical implementation, firstly, the operator selects a suitable packaging bag according to the size of the food to be packaged, and stacks them vertically in the middle of the fixed platform 81, ensuring that the opening of the packaging bag faces the packaging bag conveyor belt 9. Then, the operator can control the packaging bag clamp to open through the controller, so that the drive component 82 drives the push rod 83 to move the push plate 84 towards the side closer to the packaging bag, thereby limiting and clamping the packaging bag on both sides, ensuring the accuracy of the subsequent conveyor belt process. In some optional embodiments, the drive component 82 can be a cylinder, hydraulic telescopic rod, or electric telescopic rod structure. Afterward, the operator can control the feeding roller 85 to open through the controller, and the feeding roller 85 will sequentially guide the stacked packaging bags out of the bag assembly 8 onto the packaging bag conveyor belt 9. During the process, the bag opening component 7 is just positioned on the path of the packaging bag out of the bag assembly 8, so that the packaging bag can be directly fitted into the closed state after being exported. Between the sliding plate 75 and the fixed plate 76, it should be noted that currently, paper packaging bags or PC material packaging bags used in transmission do not use adhesive design at the opening, so that due to the material characteristics of the packaging bags, the opening gap of 0.5~1cm is maintained. This gap is compressed during the stacking of packaging bags, but once the pressure of the top stack is removed, the opening is in a normally open state with the above-mentioned opening gap, which also facilitates subsequent food packaging operations. This is understandable to those skilled in the art. Therefore, when the packaging bag is sent out of the bag delivery component 8, the bag opening naturally opens and is directly fitted onto the sliding plate 75 and the fixed plate 76. Then, the operator can control the bag opening component 7 to open through the controller. The second drive motor 73 drives the third screw 74 to rotate, and the third screw 74 drives the sliding plate 75 screwed to it to move towards or away from the bottom fixed plate 76, thereby realizing the bag opening operation.

[0032] In addition, in some optional embodiments of this utility model, to ensure the continuity of bag dispensing and bag opening, the bag dispensing component 8 can open and complete one bag transfer, and the bag opening component 7 can follow suit. After the bag opening is completed, the bag opening component 7 retracts and returns to the discharge position of the bag dispensing component 8, and then the bag dispensing component 8 opens again, and so on. Specifically, it should be noted that the third screw 74 on the bag opening component 7 can adopt a double-thread design. After the sliding plate 75 is raised to the highest point, it descends along the second path on the third screw 74 and fits against the fixed plate 76 as a spreading operation. During its retraction process, the second screw 6 is driven. It should be noted that the second screw 6 is provided with the same drive motor as the first drive motor 3 in the axial direction, so that the second screw 6... The sliding rod 71 of the threaded drive moves away from the packaging bag and drives the sliding plate 75 and the fixed plate 76 to retract into the opened packaging bag so that the packaging bag returns to the packaging bag conveyor belt 9 for continuous transmission. During this process, the second screw 6 drives the sliding rod 71 to move closer to the bag outlet assembly 8. At the same time, the feeding roller 85 on the bag outlet assembly 8 opens again. During this process, the sliding plate 75 and the fixed plate 76 are inserted into the packaging bag for the second time. This ensures the continuity of the bag pretreatment process from export to opening. In addition, as the bag opening assembly 7 moves towards the bag outlet assembly 8, the bag outlet assembly 8 performs the bag export operation at the same time and directly opens the bag after docking. This saves process time and eliminates the cumbersome operation of the bag opening assembly 7 capturing and ensuring the position of the belt after the bag is exported and then inserting it before opening the bag.

[0033] Finally, the unfolded packaging bag moves along the conveyor path of the packaging bag conveyor belt 9 away from the bag outlet assembly 8. After reaching a position parallel to the shipping conveyor belt 10, the packaging bag conveyor belt 9 stops conveying, and at the same time, the food conveyor belt 11 is activated to convey the goods to the same parallel position and then stops. The pusher assembly 12 is activated, and the third drive motor 121 drives the fourth screw 122 to push the pusher hopper 123, which sequentially conveys the food on the food conveyor belt 11 into the packaging bag on the packaging bag conveyor belt 9, completing the food packaging. Then, the conveyor belt continues to convey the food and packaging bag together to the shipping conveyor belt 10, completing the final food shipping operation. In addition, in some optional embodiments, in order to ensure the continuity of shipping, the food conveyor belt 11 can be designed as a robotic arm. The robotic arm can grab the food and place it at the pusher hopper 123, and trigger it directly when the packaging bag is about to reach a position parallel to the pusher assembly 12. This completes the food packaging and subsequent shipping operation while ensuring that the packaging bag conveyor belt 9 does not stop, further improving the continuity of this application.

[0034] In summary, by designing the bag opening component 7 at the discharge port of the bag dispensing component 8, the outgoing packaging bag can be directly opened. After each opening, the bag opening component 7 is retracted along the original path. During the second opening operation, as the bag opening component 7 moves towards the bag dispensing component 8, the bag dispensing component 8 simultaneously performs the bag dispensing operation and, after docking, directly opens the bag, saving process time and improving continuity. At the same time, the pushing component 12 pushes the food from the food conveyor belt 11 into the packaging bags on the packaging bag conveyor belt 9 and out to the delivery conveyor belt 10, further demonstrating the continuity of the equipment. The overall workflow of the equipment adopts a fully automated design, which greatly avoids food contamination caused by frequent contact between operators and food. It also solves the problem that current food packaging equipment is usually semi-automatic, and the speed of manual stacking of food packaging containers in semi-automatic designs determines the subsequent food packaging efficiency, thus preventing a significant improvement in current food packaging efficiency.
