Technical Field
[0001] This utility model belongs to the field of zipper bag technology, specifically relating to an upper zipper sealing device for a new type of zipper bag making machine. Background Technology
[0002] Zipper bags have a wide range of uses in daily life, such as packaging bags for clothes purchased online, storage bags for documents and stationery, etc. Zipper bags are generally made from non-woven fabric, transparent PE or PP plastic film through a bag making machine.
[0003] During the manufacturing process, the two sides of the zipper seal need to be heat-sealed onto the two sides of the bag body. However, when heat-sealing the zipper seal, there is a lack of heat insulation between the two sides of the zipper seal, which can easily cause the rest of the bag film to be burned or the two sides of the zipper seal to be connected together.

The fixed part is fixedly installed in the material guide hole, and the partition part is connected to the fixed part. The two sides of the partition plate have a transmission gap with the inner wall of the material guide hole.
[0007] The fixing part is provided with a cooling guide pipe, and the partition part is provided with a plurality of heat dissipation columns equidistantly transversely along its own length, and the plurality of heat dissipation columns extend into the cooling guide pipe.
[0008] The movable frame is equipped with a guide frame, and the guide frame has a material guide hole. The isolation plate includes a fixed part and multiple rotating rods. The fixed part is fixedly installed in the material guide hole, and the multiple rotating rods are rotatably connected to the fixed part. The diameter of the rotating rod is smaller than the diameter of the material guide hole, and there is a transmission gap between the rotating rod and the inner wall of the material guide hole.
[0009] The fixed part is provided with a cooling guide pipe, the rotating rod is hollow, and multiple rotating rods are connected to the cooling guide pipe.
[0010] A cooler is installed below the heat sealer.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] This utility model discloses a novel zipper sealing device for a zipper bag making machine. During heat sealing, two zipper seals are placed between two heat sealers, with the zipper ends of the zipper seals placed between two partition plates. The partition plates separate the two sides of the zipper seals, thus preventing the two sides of the zipper seals from sticking together during heat sealing. Attached Figure Description

[0021] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation. Example
[0022] like Figures 1-4As shown, this embodiment provides a novel zipper sealing device for a zipper bag making machine, including a frame 1, a movable frame 2, and two heat sealers 3. The movable frame 2 is movably mounted on the frame 1. The frame 1 is provided with an adjusting screw 4 that is threadedly engaged with the movable frame 2. The two heat sealers 3 are symmetrically installed on both sides of the movable frame 2. Two partition plates 5 are installed on the movable frame 2, located between the two heat sealers 3, and a gap is provided between the two partition plates for the zipper portion of the zipper seal to pass through. During heat sealing, the two zipper seals are placed between the two heat sealers 3, with the zipper end of the zipper seal placed between the two partition plates 5. The partition plates 5 separate the two sides of the zipper seal, thus preventing the two sides of the zipper seal from sticking together during heat sealing.
[0023] Furthermore, a guide frame 6 is installed on the movable frame 2, and a guide hole 7 is opened on the guide frame 6. The partition plate 5 includes a fixing part 8 and a partition part 9. The fixing part 8 is fixedly installed in the guide hole 7, and the partition part 9 is connected to the fixing part 8. The two sides of the partition plate have a transmission gap with the inner wall of the guide hole 7. Specifically, a cooling guide pipe 10 is provided in the fixing part 8, and multiple heat dissipation columns 11 are arranged horizontally at equal intervals along its own length in the partition part 9. The multiple heat dissipation columns 11 extend into the cooling guide pipe 10. It conducts the zipper seal through the guide hole 7 and separates the two sides of the zipper seal through the partition part 9. When heat sealing is performed for a long time, the partition part 9 will be heated. The zipper seal will be heated by the partition part 9. After leaving the partition plate, the two sides of the zipper seal may still stick together. After heating, it is easier to stick together. Coolant is transmitted through the cooling guide pipe 10, and the partition part 9 is cooled at regular intervals through the multiple heat dissipation columns 11 to prevent the partition part 9 from being heated for a long time.
[0024] Furthermore, a cooler 13 is installed below the heat sealer 3. After heat sealing, the zipper seal is cooled by the cooler 13 to ensure a firm adhesion. Example
[0025] like Figures 5-7 As shown, this embodiment provides a novel zipper sealing device for a zipper bag making machine, including a frame 1, a movable frame 2, and two heat sealers 3. The movable frame 2 is movably mounted on the frame 1. The frame 1 is provided with an adjusting screw 4 that is threadedly engaged with the movable frame 2. The two heat sealers 3 are symmetrically installed on both sides of the movable frame 2. Two partition plates 5 are installed on the movable frame 2, located between the two heat sealers 3, and a gap is provided between the two partition plates for the zipper portion of the zipper seal to pass through. During heat sealing, the two zipper seals are placed between the two heat sealers 3, with the zipper end of the zipper seal placed between the two partition plates 5. The partition plates 5 separate the two sides of the zipper seal, thus preventing the two sides of the zipper seal from sticking together during heat sealing.
[0026] Furthermore, a guide frame 6 is installed on the movable frame 2, and a guide hole 7 is opened on the guide frame 6. The isolation plate 5 includes a fixed part 8 and multiple rotating rods 12. The fixed part 8 is fixedly installed in the guide hole 7, and the multiple rotating rods 12 are rotatably connected to the fixed part 8. The diameter of the rotating rods 12 is smaller than the diameter of the guide hole 7, and there is a transmission gap between them and the inner wall of the guide hole 7. Specifically, a cooling guide pipe 10 is provided in the fixed part 8, the rotating rods 12 are hollow, and the multiple rotating rods 12 are connected to the cooling guide pipe 10. It conducts the zipper seal through the guide hole 7 and separates the two sides of the zipper seal through the rotating rod 12. During long-term heat sealing, the rotating rod 12 will be heated, so the zipper seal will be heated by the rotating rod 12. After leaving the separator, the two sides of the zipper seal may still stick together. After heating, it is easier to stick together. Cooling fluid is transmitted through the cooling guide pipe 10 and enters the rotating rod 12 for timed heat dissipation to prevent the rotating rod 12 from being heated for a long time.
[0027] Furthermore, a cooler 13 is installed below the heat sealer 3. After heat sealing, the zipper seal is cooled by the cooler 13 to ensure a firm adhesion.
[0028] The foregoing has shown and described the basic principles and main features of this invention, as well as its advantages. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
