Description

Technical Field

[0001] This utility model relates to the field of clay packaging machine technology, and in particular to a sealing knife device for a clay packaging machine. Background Technology

[0002] The metallurgical clay packaging machine is a specialized piece of equipment used for the automatic packaging of metallurgical clay products in the later stages of production. It is mainly designed to achieve efficient packaging of clay products produced using different molding processes (pressure briquetting, spiral extrusion, etc.). The sealing knife device is used for heat sealing the clay packaging.

[0003] Currently available sealing devices have low sealing efficiency. Typically, workers need to feed the packaging containing clay into the device, and then the sealing knife heat-seals the packaging. Therefore, the sealing device cannot continuously heat-seal multiple clay packaging packages, which greatly reduces the packaging efficiency of clay. Utility Model Content

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.

[0020] Reference Figure 1-4 A sealing knife device for a clay packaging machine includes a fixed frame 1, a support column 2 fixedly connected to the bottom surface of the fixed frame 1, a limit baffle 3 fixedly connected to the top surface of the fixed frame 1, a support frame 4 fixedly connected to the back of the fixed frame 1, a fixed platform 5 fixedly connected to the front of the fixed frame 1, a fixed frame 6 fixedly connected to the bottom surface of the fixed platform 5, a first electric push rod 7 fixedly connected to the inner wall of the fixed frame 6, a connecting frame 8 fixedly connected to the output end of the first electric push rod 7, and a positioning support mechanism provided on the top surface of the connecting frame 8. The positioning support mechanism consists of a tray 9, a cutting groove 10, and a positioning camera 11. The tray 9 is rectangular and made of metal. The metal tray 9 has higher strength, is less prone to deformation and damage under stress, and is more durable. The tray 9 is fixedly connected to the top surface of the connecting frame 8, and the surface of the tray 9 is slidably connected to the inner wall of the fixed platform 5. The positioning camera 11 is fixedly connected to the inner wall of the tray 9 for... The support frame 4 is equipped with a cutting component to detect the movement of the packaging bag and facilitate its lifting. A buffer sealing mechanism is located below the support frame 4. This mechanism consists of a limiting shaft 16, a fixed plate 17, a sealing knife 18, a heating rod 19, and a spring 20. Multiple limiting shafts 16 are symmetrically arranged around the vertical center line of the front of the fixed plate 13, assisting the sealing knife 18 in lifting and lowering, thus improving stability. The limiting shafts 16 are slidably connected to the inner wall of the fixed plate 13. The fixed plate 17 is fixedly connected to the bottom end of the limiting shafts 16. The sealing knife 18 is fixedly connected to the bottom surface of the fixed plate 17. The heating rod 19 is fixedly connected to the inner wall of the sealing knife 18. The spring 20 is fixedly connected to the top surface of the fixed plate 17 and the bottom surface of the fixed plate 13, used for heat-sealing the packaging bag and facilitating buffering of sealing pressure. A conveying component is located on the front of the fixed frame 1.

[0021] Specifically, the cutting assembly consists of a second electric push rod 12, a fixed plate 13, a fixed block 14, and a cutting tool 15. The second electric push rod 12 is fixedly connected to the inner wall of the support frame 4, the fixed plate 13 is fixedly connected to the output end of the second electric push rod 12, the fixed block 14 is fixedly connected to the bottom surface of the fixed plate 13, and the cutting tool 15 is fixedly connected to the bottom surface of the fixed block 14. The surface of the cutting tool 15 is slidably connected to the inner wall of the cutting groove 10, which is used to cut excess packaging bags and facilitates the downward movement of the buffer sealing mechanism.

[0022] Specifically, the conveying assembly consists of a servo motor 21, a transmission roller 22, and a conveyor belt 23. The servo motor 21 is fixedly connected to the front of the fixed frame 1, and the output end of the servo motor 21 is rotatably connected to the inner wall of the fixed frame 1. The transmission roller 22 is rotatably connected to the inner wall of the fixed frame 1, and the transmission roller 22 is fixedly connected to the output end of the servo motor 21. The inner wall of the conveyor belt 23 meshes with the surface of the transmission roller 22, which is used to drive multiple packaging bags to move continuously, thereby improving the packaging production efficiency.

[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0024] In use: First, place multiple clay packages sequentially above the conveyor belt 23, with the openings facing forward. Start the servo motor 21 to drive the transmission roller 22 to rotate along the inner wall of the fixed frame 1. Through the engagement of the transmission roller 22 and the conveyor belt 23, the packages move to the right. Start the positioning camera 11 to collect image information from above. When the package is detected to have moved to the designated position, start the first electric push rod 7 to push the tray 9 upward through the connecting frame 8 to contact the package. At the same time, start the heating rod 19 to heat the sealing knife 18. Start the second electric push rod 12 to push the limiting shaft 16 downward through the fixed plate 13. The movement of the limiting shaft 16 drives the fixed plate 17 and the sealing knife 18 to move downwards and contact the packaging bag, which can then cooperate with the tray 9 to heat seal the packaging bag. At the same time, the sliding connection between the fixed plate 13 and the limiting shaft 16 can assist the fixed plate 13 to continue moving downwards to compress the spring 20. The rebound force generated by the spring 20 can improve the heat sealing stability. The movement of the fixed plate 13 drives the fixed block 14 and the cutting knife 15 to move downwards into the cutting groove 10, which can then cut the excess packaging bag. By repeating the above actions, multiple clay packaging bags can be continuously sealed.

[0025] In summary, this clay packaging machine uses a sealing knife device to place multiple clay bags sequentially on the conveying assembly with the opening facing forward. Activating the conveying assembly drives the bags to move to the right, activating the first electric push rod 7 and the positioning and supporting mechanism to position and lift the bags. Activating the cutting assembly drives the buffer sealing mechanism to move downwards, thus cooperating with the positioning and supporting mechanism to heat-seal the bags and simultaneously cut excess bags. Repeating these actions allows for continuous packaging of multiple clay bags, achieving the goal of facilitating continuous packaging production of clay bags. This avoids the problem of significantly reduced clay packaging efficiency caused by existing sealing knife devices typically only being able to seal one bag at a time, thus solving the problems mentioned in the background art.
