Description

Technical Field

[0001] This utility model belongs to the field of flame-retardant PVA composite high-temperature film air ring cooling technology, specifically a flame-retardant PVA composite high-temperature film air ring cooling mechanism. Background Technology

[0002] PVC's main component is polyvinyl chloride, a slightly yellowish, translucent material with a glossy appearance. Its transparency is better than polyethylene and polypropylene, but worse than polystyrene. Depending on the amount of additives used, it is classified as soft or rigid PVC. Soft PVC products are flexible and tough, with a sticky feel, while rigid PVC products have a harderness than low-density polyethylene but lower than polypropylene, and may exhibit whitening at bending points. Common products include: sheets, pipes, shoe soles, toys, doors and windows, wire sheathing, stationery, etc. It is a polymer material in which one chlorine atom replaces one hydrogen atom in polyethylene.

[0003] The air ring is an important component of blown film machines in plastic processing machinery, responsible for cooling and shaping the inflated film bubble. The air ring has a significant impact on the quality and output of blown film products. PVC is the raw material for making flame-retardant PVA composite high-temperature films. In the process of manufacturing flame-retardant PVA composite high-temperature films, the air ring cooling mechanism is required for processing.

[0004] Meanwhile, application number CN216300155U, entitled "High-Frequency Cooling Air Ring," describes a high-frequency cooling air ring comprising a chassis with a circular hole in the center. A connecting ring is fixedly connected to the inner wall of the circular hole, and a cooling ring is fixedly connected to the top of the connecting ring. A cover is provided on the top of the chassis, and a ring body is fixedly connected to the inner wall of the bottom of the cover. Multiple pressure plates for pressurization are fixedly connected to the top of the ring body. This invention, through the arrangement of the ring body, pressure plates, and connecting ring, with the pressure plates directly welded to the ring body, facilitates the manufacturing process. Furthermore, the internal structure of the ring body, pressure plates, and connecting ring simplifies airflow direction while achieving the structural effectiveness of a traditional air ring. This reduces costs while ensuring the air ring's performance. The integrated assembly design also simplifies the installation process, reducing the failure rate of the air ring during production and improving production efficiency.

[0005] In the above-mentioned technical solution, when the cooling air ring is used to cool the PVA composite high-temperature film, the cooling air ring cannot prevent dust from being blown out of the air outlet. As a result, the dust attached to the airflow is easily stuck in the flame-retardant PVA composite high-temperature film, thus affecting the processing quality of the flame-retardant PVA composite high-temperature film.

[0006] Therefore, a flame-retardant PVA composite high-temperature film air ring cooling mechanism is proposed to address the above problems. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant PVA composite high-temperature film air ring cooling mechanism, including a cooling mechanism body, wherein a dustproof disassembly component is installed inside the cooling mechanism body;

[0009] The dustproof disassembly assembly includes an arc-shaped dustproof plate. An arc-shaped dustproof plate is provided inside the cooling mechanism body. The arc-shaped dustproof plate is attached to the air outlet of the cooling mechanism body. Insert blocks are symmetrically installed on the surface of the arc-shaped dustproof plate. Fastening blocks are symmetrically installed on the surface of the cooling mechanism body. The insert blocks are inserted into the fastening blocks. Movable rods are symmetrically rotatably connected to the surface of the fastening blocks. Connecting plates are installed on the surface of the movable rods. Moving blocks are slidably connected in a groove on the surface of the connecting plates. Positioning strips are installed between the two moving blocks. Stabilizing components are installed on the surface of the fastening blocks.

[0010] Preferably, a positioning rod is installed at the bottom of the positioning strip, and the surfaces of the insert block and the fastening block are provided with insertion holes adapted to the positioning rod. The positioning rod is inserted into the insertion holes on the surfaces of the insert block and the fastening block. The insertion holes on the surfaces of the insert block and the fastening block are used to fix the positioning strip in the horizontal and vertical positions.

[0011] Preferably, a guide rod is slidably connected in the through hole opened on the surface of the movable block, and both ends of the guide rod pass through the movable block and are installed in the groove opened on the surface of the connecting plate.

[0012] Preferably, a return spring is sleeved on the surface of the guide rod, one end of the return spring is connected to the moving block, and the other end of the return spring is installed in a groove opened on the surface of the connecting plate.

[0013] Preferably, a torsion spring is fitted onto the surface of the movable rod, one end of the torsion spring is connected to the fastening block, and the other end of the torsion spring is connected to the connecting plate.

[0014] Preferably, the stabilizing component includes a fixing plate, one end of the movable rod is mounted with the fixing plate, a fixing rod is slidably connected in a through hole on the surface of the fixing plate, one end of the fixing rod passes through the fixing plate and is inserted into a fixing hole on the surface of the fastening block, and the fastening block has two fixing holes on its surface for positioning the horizontal and vertical positions of the connecting plate.

[0015] Preferably, a second return spring is sleeved on the surface of the fixing rod, one end of the second return spring is connected to the fixing rod, and the other end of the second return spring is connected to the fixing plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model incorporates a dustproof disassembly assembly. When installing the arc-shaped dustproof plate inside the cooling mechanism body, the arc-shaped dustproof plate is first placed inside the cooling mechanism body. At this time, the insert block on the arc-shaped dustproof plate is inserted into the fastening block. Then, the operator pulls the positioning strip, causing the positioning rod on the positioning strip to disengage from the insertion hole on the surface of the fastening block. The positioning strip then drives the moving block to slide in the groove on the surface of the connecting plate. During the movement, the moving block slides on the surface of the guide rod, which guides the movement of the moving block to prevent it from shifting position. Then, the connecting plate is rotated by the movable rod, causing the connecting plate to move and the moving block to a vertical position. Then, the return spring pulls the moving block downwards, causing the moving block to bring the positioning strip tightly against the surface of the insert block. At this time, the positioning rod on the positioning strip is inserted into the insertion hole on the surface of the insert block, thus fixing the position of the insert block. The air blown out of the air vent of the cooling mechanism body is filtered through the arc-shaped dustproof plate.

[0018] 2. This utility model incorporates a stabilizing component. When the connecting plate is adjusted, the fixing rod inside the through hole on the surface of the fixing plate is pulled. One end of the fixing rod disengages from the fixing hole on the surface of the fastening block. This causes the fixing rod to deform, and the second return spring repositions the fixing rod. When the connecting plate is rotated and its position is adjusted, the operator releases the fixing rod. The second return spring is no longer under tension, allowing the fixing rod to re-insert into the fixing hole on the surface of the fastening block. This stabilizes the position of the connecting plate and prevents it from shifting during use. Attached Figure Description

[0025] 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.

[0026] like Figures 1 to 5 As shown, this utility model provides a drying device for metal film, including a cooling mechanism body 1, and a dustproof disassembly component 2 is installed inside the cooling mechanism body 1;

[0027] The dustproof disassembly assembly 2 includes an arc-shaped dustproof plate 21. The arc-shaped dustproof plate 21 is installed inside the cooling mechanism body 1. The arc-shaped dustproof plate 21 is attached to the air outlet of the cooling mechanism body 1. Insert blocks 22 are symmetrically installed on the surface of the arc-shaped dustproof plate 21. Fastening blocks 23 are symmetrically installed on the surface of the cooling mechanism body 1. Insert blocks 22 are inserted into the inside of fastening blocks 23. Movable rods 211 are symmetrically rotatably connected to the surface of fastening blocks 23. Connecting plates 24 are installed on the surface of movable rods 211. Moving blocks 25 are slidably connected in the groove opened on the surface of connecting plates 24. Positioning strips 26 are installed between two moving blocks 25. Stabilizing components 3 are installed on the surface of fastening blocks 23.

[0028] Specifically, such as Figure 1As shown, a positioning rod 27 is installed at the bottom of the positioning strip 26. The surfaces of the insert block 22 and the fastening block 23 are provided with insertion holes that are compatible with the positioning rod 27. The positioning rod 27 is inserted into the insertion holes on the surfaces of the insert block 22 and the fastening block 23. The insertion holes on the surfaces of the insert block 22 and the fastening block 23 are used to fix the positioning strip 26 in the horizontal and vertical positions. A guide rod 28 is slidably connected in the through hole on the surface of the moving block 25. Both ends of the guide rod 28 pass through the moving block 25 and are installed in the groove on the surface of the connecting plate 24. A return spring 29 is sleeved on the surface of the guide rod 28. One end of the return spring 29 is connected to the moving block 25, and the other end of the return spring 29 is installed in the groove on the surface of the connecting plate 24. A torsion spring 210 is sleeved on the surface of the movable rod 211. One end of the torsion spring 210 is connected to the fastening block 23, and the other end of the torsion spring 210 is connected to the connecting plate 24.

[0029] In this implementation scheme: When installing the arc-shaped dustproof plate 21 inside the cooling mechanism body 1, the arc-shaped dustproof plate 21 is first placed inside the cooling mechanism body 1. At this time, the insert block 22 on the arc-shaped dustproof plate 21 is inserted into the fastening block 23. Then, the operator pulls the positioning strip 26, causing the positioning rod 27 on the positioning strip 26 to disengage from the insertion hole on the surface of the fastening block 23. At this time, the positioning strip 26 drives the moving block 25 to slide in the groove on the surface of the connecting plate 24. During the movement, the moving block 25 slides on the surface of the guide rod 28, and the guide rod 28 can move the moving block 25. The moving block 25 is guided to avoid positional deviation during movement. Then, the connecting plate 24 is rotated by the movable rod 211, causing the connecting plate 24 to move 90 degrees, so that the moving block 25 moves to a vertical position. Then, the reset spring 29 pulls the moving block 25 downward. The moving block 25 then drives the positioning strip 26 to stick tightly to the surface of the insert block 22. At this time, the positioning rod 27 on the positioning strip 26 is inserted into the insertion hole opened on the surface of the insert block 22, thereby fixing the position of the insert block 22. The air blown out of the air vent of the cooling mechanism body 1 is filtered along the arc-shaped dustproof plate 21.

[0030] Please refer to Example 2 Figure 1-5 The difference between this embodiment and embodiment 1 is that the stabilizing component 3 includes a fixed plate 31, one end of the movable rod 211 is mounted with the fixed plate 31, a fixed rod 32 is slidably connected in the through hole opened on the surface of the fixed plate 31, one end of the fixed rod 32 passes through the fixed plate 31 and is inserted into the fixed hole opened on the surface of the fastening block 23, and the fastening block 23 has two fixed holes opened on its surface for positioning the horizontal and vertical positions of the connecting plate 24.

[0031] Specifically, such as Figure 1-5As shown, a second return spring 33 is sleeved on the surface of the fixed rod 32. One end of the second return spring 33 is connected to the fixed rod 32, and the other end of the second return spring 33 is connected to the fixed plate 31.

[0032] In this implementation scheme: When the position of the connecting plate 24 is adjusted, the fixing rod 32 in the through hole on the surface of the fixing plate 31 is pulled. At this time, one end of the fixing rod 32 disengages from the fixing hole on the surface of the fastening block 23. The fixing rod 32 pulls the second return spring 33 to deform. The second return spring 33 can reset the position of the fixing rod 32. Then, the connecting plate 24 is rotated. After the position of the connecting plate 24 is adjusted, the operator releases the fixing rod 32. The second return spring 33 is no longer under tension, thereby driving the fixing rod 32 to re-insert into the fixing hole on the surface of the fastening block 23. This stabilizes the position of the connecting plate 24 and prevents the connecting plate 24 from shifting during use.
