Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a food packaging sealing device. Background Technology

[0002] Food packaging sealing equipment is specialized machinery used in the food processing and packaging industry to seal food packaging bags. This equipment utilizes a unique foot-driven structure design, converting the operator's foot strength into sealing power, achieving precise alignment and efficient sealing of food packaging bags. It effectively ensures the airtightness of food packaging, preventing food from becoming damp or spoiling, while simultaneously improving packaging efficiency, providing food production and processing enterprises with a convenient and reliable packaging solution.

[0003] Traditional food packaging sealing equipment suffers from numerous problems in practical use. Most rely on manual operation, requiring operators to hold the packaging bag with one hand and press the sealing device with the other. This process is not only cumbersome but also makes it difficult to ensure the bag's stable position with one hand, easily leading to misalignment and uneven sealing, increasing the defect rate. Furthermore, manual operation is labor-intensive, and prolonged work can easily cause operator fatigue, thus affecting sealing efficiency and quality. Especially when dealing with packaging bags that are difficult to seal, manual operation struggles to meet the requirements for accuracy and efficiency, failing to meet the urgent needs of the modern food packaging industry for efficient and stable production. Therefore, we propose a new food packaging sealing device. Utility Model Content

[0004] One of the technical problems this application aims to solve is that existing food processing equipment relies on manual operation, which not only easily causes operator fatigue during long working hours, but also makes it difficult to ensure the stable position of the packaging bag, which can easily lead to misalignment and uneven sealing, increasing the defect rate. To address the aforementioned technical problems, this application provides a food packaging sealing device, including a workbench. A connecting bracket is movably connected to one side of the workbench. A roller is movably connected to the outer wall of the upper end of the connecting bracket. A return spring is fixedly connected to the middle of the connecting bracket. A first connecting rod is movably connected to the lower end of the connecting bracket. A second connecting rod is movably connected to the lower end of the first connecting rod. A connecting member is movably connected to the lower end of the second connecting rod. A foot pedal is fixedly connected to the lower end of the connecting member. A connecting shaft is movably connected to the outer wall of one side of the foot pedal. Connecting blocks are movably connected to both sides of the connecting shaft.

[0005] In some embodiments, a fixed bracket is fixedly connected to the lower end of the workbench, a lower sealing device is fixedly connected to the outer wall of the upper end of the workbench, an upper sealing device is movably connected to the upper end of the lower sealing device, and a limit groove is formed on one side of the outer wall of the upper end of the upper sealing device.

[0006] In some embodiments, the limiting groove opened on the outer wall of the upper end of the upper sealing device is correspondingly connected to the roller provided on the upper end of the connecting bracket.

[0007] In some embodiments, the first connecting rod and the second connecting rod are at an angle under normal circumstances.

[0008] In some embodiments, the upper end of the reset spring is fixedly connected to the lower end of the worktable.

[0009] In some embodiments, the connecting block is fixedly connected to the lower side wall of the workbench.

[0010] In some embodiments, the lower end of the upper sealing device is connected to the middle of the upper end of the lower sealing device.

[0011] In some embodiments, the workbench is provided with slots that are movably connected to the outer wall of the connecting bracket.

[0012] This utility model has at least the following beneficial effects: In use, this device, through the ingenious design of a foot pedal, a first connecting rod, and a second connecting rod, allows the user to operate without using their hands; the sealing operation can be initiated simply by stepping on the pedal. The connection between the foot pedal and the connecting shaft allows the force of the foot to be transmitted to the connecting bracket via a lever, thereby enabling the connecting bracket to precisely align the upper and lower sealing devices, completing the sealing process. This design effectively frees up the hands, avoids the instability caused by manual pressing with one hand, reduces errors during the sealing process, and improves work efficiency, making it particularly suitable for packaging bags that are difficult to seal.

[0013] In use, this device transmits sealing pressure via foot pedaling, which is less strenuous than manual pressing. The angled connection between the first and second connecting rods transforms into a vertical connection under the action of the foot pedal, allowing the connecting bracket to move vertically downwards effectively, thereby generating sufficient sealing pressure. Applying force through the foot is more labor-saving than manual operation, enabling the sealing process to be completed in a shorter time, significantly improving work efficiency and reducing physical strain on the operator.

[0014] In this invention, the application of a return spring ensures that the device quickly returns to its original position when not in use after being stepped on by a foot, preventing damage from prolonged load. This design allows the device to maintain efficient operation while also possessing good durability and safety, thus extending its service life. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a food packaging sealing device, including a workbench 2, a connecting bracket 6 movably connected to one side of the workbench 2, a slot on the workbench 2 movably connected to the outer wall of the connecting bracket 6, a roller 7 movably connected to one side of the upper end of the connecting bracket 6, a return spring 8 fixedly connected to the middle of the connecting bracket 6, the upper end of the return spring 8 fixedly connected to the lower end of the workbench 2, a first connecting rod 9 movably connected to the lower end of the connecting bracket 6, a second connecting rod 10 movably connected to one side of the lower end of the first connecting rod 9, the first connecting rod 9 and the second connecting rod 10 forming an angle under normal conditions, a connecting piece 11 movably connected to the lower end of the second connecting rod 10, a foot pedal 12 fixedly connected to the lower end of the connecting piece 11, a connecting shaft 13 movably connected to one side of the outer wall of the foot pedal 12, connecting blocks 14 movably connected to both sides of the connecting shaft 13, and the connecting blocks 14 fixedly connected to the lower side wall of the workbench 2.

[0019] In this embodiment, a workbench 2 is designed with a groove on one side, and a connecting bracket 6 is movably connected within the groove. A roller 7 is connected to the upper side of the connecting bracket 6, and one side of the roller 7 is correspondingly connected to the upper sealing device 4 and the limiting groove 5 opened on its upper outer wall. The lower end of the connecting bracket 6 extends to the lower side of the workbench 2 and is movably connected to a first connecting rod 9. A connecting piece 11 is movably connected to the lower end of the first connecting rod 9 via a second connecting rod 10. A foot pedal 12 is fixedly connected to the lower end of the connecting piece 11. The first connecting rod 9 and the second connecting rod 10 are connected at an angle. A connecting block 14 is connected to one side of the foot pedal 12 via a connecting shaft 13. The connecting block 14 is fixedly connected to the lower side of the fixed bracket 1. A return spring 8 is connected to the lower end of the workbench 2 at the upper middle part of the connecting bracket 6. The device features a side-fixed connection, allowing the user to step on the foot pedal 12 during sealing operations and offset downwards around the connecting shaft 13. This causes the foot pedal 12 to move the first connecting rod 9 and the second connecting rod 10 downwards, changing their angled connection to a vertical connection. This, in turn, causes the connecting bracket 6 to move vertically downwards, pulling the return spring 8. The roller 7 on one side of the upper end of the connecting bracket 6 then presses against the upper sealing device 4 through the limiting groove 5, allowing the upper sealing device 4 to connect with the lower sealing device 3 for sealing. This method frees up the hands, provides better fixation for packaging bags that are difficult to seal, and transmits sealing force through the foot, which is less strenuous than pressing by hand, significantly improving work efficiency.

[0020] Example 2: Please refer to Figure 1-3 A fixed bracket 1 is fixedly connected to the lower end of the workbench 2. A lower sealing device 3 is fixedly connected to the upper outer wall of the workbench 2. An upper sealing device 4 is movably connected to the upper end of the lower sealing device 3. The lower end of the upper sealing device 4 is correspondingly connected to the middle of the upper end of the lower sealing device 3. A limiting groove 5 is opened on one side of the upper outer wall of the upper sealing device 4. The limiting groove 5 opened on one side of the upper outer wall of the upper sealing device 4 is correspondingly connected to the roller 7 provided on one side of the upper end of the connecting bracket 6.

[0021] In this embodiment, a fixed bracket 1 is fixedly connected to the lower end of the workbench 2, which supports the device. A lower sealing device 3 is fixedly connected to the upper end of the workbench 2, and an upper sealing device 4 is movably connected to the upper end of the lower sealing device 3. The lower sealing device 3 and the upper sealing device 4 are existing technologies. Existing technologies can use a pressing method, connecting the upper sealing device 4 and the lower sealing device 3 to complete the sealing operation during heating. However, existing technologies mostly use manual pressing, so the food packaging bag can only be held with one hand while the other hand presses it. Holding with one hand may cause misalignment of the seal, resulting in packaging defects. To address this, the upper sealing device 4... A limiting groove 5 is provided on one side of the connecting bracket 6. The limiting groove 5 is connected to the roller 7 provided on the upper side of the connecting bracket 6. When the connecting bracket 6 is offset by the foot pedal 12 and moves downward, the roller 7 will also move downward. At this time, the roller 7 will be connected to the limiting groove 5, which will drive the upper sealing device 4 to move downward, thereby connecting the upper sealing device 4 with the lower sealing device 3 to complete the sealing operation. Conversely, when the foot pedal 12 is released, the reaction force of the return spring 8 will cause the first connecting rod 9 and the second connecting rod 10 to reconnect at an angle. The connecting bracket 6 and the roller 7 will move upward, so that the upper sealing device 4 and the lower sealing device 3 will be reset for subsequent sealing operations.
