Description

Technical Field

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

[0002] Food packaging bags are a type of packaging material designed to protect food from external contamination during storage, transportation, and sales, while maintaining the original flavor, nutritional value, and appearance of the food. These bags not only act as physical barriers, preventing food from being affected by oxygen, moisture, microorganisms, physical impacts, odors, and light, but also serve as information carriers, conveying information about the food to consumers, such as ingredients, production date, and shelf life. A food packaging bag sealing machine is a specialized piece of machinery used for sealing food packaging bags. Sealing machines are an indispensable piece of equipment in the food packaging industry, playing a vital role in improving packaging efficiency and ensuring packaging quality.

[0003] A search revealed that Chinese patent CN218142491U discloses a method that addresses the poor fixing effect and inconvenience of adjustment of conventional sealing machines, which easily affects daily usage efficiency. Therefore, it uses clamps to clamp and fix the sealing machine, ensuring its placement stability and allowing for height adjustment to meet different usage needs and improve usage flexibility.

[0004] The sealing machine described above is designed to improve stability during use. However, when the sealing machine is not in use, the sealing area is usually directly exposed to the air, where dust and lint are often present. The sealing area is not designed to block dust, which can lead to the sealing area becoming contaminated with dust and lint. Consequently, when the sealing machine is in use, the sealed packaging bags may become covered with dust and lint, resulting in loose seals and reduced sealing quality. Utility Model Content

[0031] 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.

[0032] As attached Figure 1-6 As shown, one embodiment of this utility model is provided: a novel food packaging bag sealing machine, including a sealing machine body 1, and a protective component is provided on one side of the sealing machine body 1;

[0033] The protective assembly includes a fixing frame 2, which is fixedly connected to one side of the sealing machine body 1. Sliding sleeves 3 are slidably connected to both sides of the fixing frame 2. A threaded pipe 4 is connected through one side of the sliding sleeve 3, and a fastening bolt 5 is threaded inside the threaded pipe 4. A connecting rod 6 is fixedly connected to one side of the sliding sleeve 3. A protective shell 7 is provided at one end of each connecting rod 6. Two connecting blocks 8 are fixedly connected to one side of each protective shell 7. One connecting block 8 has a limit hole 9 inside. An installation groove 10 is provided at one end of each connecting rod 6. A fixing shell 11 is fixedly connected to the upper surface of one connecting rod 6. A pull rod 12 is slidably connected to the surface. A limiting block 13 is fixedly connected to the middle of the pull rod 12. A spring 14 is fixedly connected to the upper surface of the limiting block 13. The spring 14 is sleeved on the outside of the pull rod 12. One end of the spring 14 is fixedly connected to the inner wall of the fixed shell 11. The sliding sleeve 3 facilitates the movement of the protective shell 7 through the connecting rod 6. The fastening bolt 5 facilitates the limiting and fixing of the moved sliding sleeve 3 under the action of the threaded tube 4. The limiting block 13 helps to prevent the pull rod 12 from being pulled out of the fixed shell 11. The spring 14 pushes the pull rod 12, making it easier for the pull rod 12 to engage more tightly with the limiting hole 9.

[0034] As attached Figure 6 As shown, an adjustment assembly is provided on the lower surface of the sealing machine body 1. The adjustment assembly includes a base plate 15, which is fixedly connected to the lower surface of the sealing machine body 1. Two fixing blocks 16 are fixedly connected to both sides of the sealing machine body 1. Threaded holes 17 are opened inside the two fixing blocks 16, and through holes 18 are opened inside the other two fixing blocks 16. The threaded holes 17 facilitate the installation of the screw 19, and the through holes 18 facilitate the installation of the limit rod 21.

[0035] As attached Figure 2As shown, a screw 19 is threadedly connected to the inside of the threaded hole 17. A knob 20 is fixedly connected to one end of the screw 19. A limit rod 21 is slidably connected inside the through hole 18. One end of one limit rod 21 is fixedly connected to a support plate 22. One end of one screw 19 is rotatably connected to the upper surface of the support plate 22. Multiple casters 23 are fixedly connected to the lower surface of the base plate 15. The limit rod 21 is used to limit the movement of the support plate 22 when the screw 19 pushes it. The casters 23 are used to facilitate the movement of the sealing machine.

[0036] As attached Figure 5 As shown, the pull rod 12 passes through one end of one of the connecting rods 6, so as to engage with the limiting hole 9.

[0037] Working principle: When the sealing area of ​​the sealing machine needs to be covered without using the sealing machine, tighten the fastening bolt 5 to release the phenomenon that one end of the fastening bolt 5 passes through the sliding sleeve 3 and abuts against the fixed frame 2. Then, it is convenient for the sliding sleeve 3 to slide to the bottom outside the fixed frame 2. It is convenient to indirectly drive the protective shell 7 to fall through the connection of the connecting rod 6. Then tighten the fastening bolt 5 from the inside of the threaded tube 4 so that the fastening bolt 5 abuts against the fixed frame 2, which is convenient to limit the position of the sliding sleeve 3. This makes it convenient for the protective shell 7 to cover the sealing area of ​​the sealing machine when it falls, thereby reducing the impact of dust and lint on the sealing area.

[0038] When disassembling the protective shell 7, pull the lever 12 so that one end of the lever 12 is disengaged from the inside of the limiting hole 9, which makes it easy for the connecting block 8 to be released from the limit. Then, pull out the connecting block 8 inside the mounting groove 10, which makes it easy for the two connecting blocks 8 to separate the protective shell 7 from one end of the two connecting rods 6, making it easy to disassemble the protective shell 7 for maintenance and replacement. When installing, insert the connecting block 8 into the corresponding mounting groove 10, and then pull the lever 12 to insert one end into the inside of the limiting hole 9, which improves the convenience of replacing the protective shell 7.

[0039] When it is necessary to lift the sealing machine body 1, first place the sealing machine body 1 horizontally so that the two support plates 22 are suspended in the air, then turn the knob 20 so that the knob 20 drives the screw 19 to rotate, so that the screw 19 can move downward under the action of the threaded hole 17. Then, under the limiting action of the limiting rod 21 sliding inside the through hole 18, it is easy to push the support plate 22 to move down, so that the support plate 22 is separated from the bottom plate 15, thereby making it easier to lift the bottom of the sealing machine body 1, which helps to adapt to packaging bags of different thicknesses for loading different foods.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
