Description

Technical Field

[0001] This utility model belongs to the field of blown film machine technology, specifically relating to a blown film machine air ring with temperature monitoring function. Background Technology

[0002] The blown film machine air ring is one of the key components of the blown film machine. It is mainly used to cool and shape the film bubble during the plastic film production process, which directly affects the quality, production efficiency and stability of the film. During the blown film process, the molten plastic is extruded through the die head to form a film bubble. The air ring quickly reduces the temperature of the film bubble by blowing out cold air (usually room temperature air or low temperature air that has been refrigerated), so that it solidifies and shapes.

[0003] During prolonged continuous operation, the airflow generates high-frequency friction against the inner wall of the air ring. This mechanical action continuously converts kinetic energy into heat, which gradually accumulates within the casing over time. If the casing temperature exceeds a safe threshold, it will trigger a series of serious consequences. Excessively high temperatures will damage the physical and chemical properties of the casing material, causing it to soften and deform, thus affecting the structural stability of the air ring itself and potentially leading to equipment malfunctions or even safety hazards.

[0016] 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.

[0017] Please see Figure 1-4 The present invention provides the following technical solution: a blown film machine air ring with temperature monitoring function, including an air ring 1, four connection ports 2 are installed at equal intervals on the outer wall of the air ring 1, a temperature measuring port 3 is opened on the surface of the air ring 1, the inner wall of the temperature measuring port 3 is in contact with the outer wall of the detection end of the temperature measuring probe 4, the other end of the temperature measuring probe 4 is connected to a temperature monitoring instrument 5, the model of the temperature monitoring instrument 5 is: 905-T1 central thermometer, the temperature measuring probe 4 and the temperature monitoring instrument 5 constitute the overall structure of the thermometer; After molten plastic is extruded into a tubular film bubble through the die head, it needs to be rapidly cooled and solidified to set its shape. The air ring 1 blows a high-speed cooling airflow evenly onto the surface of the film bubble through the annular air outlet, carrying away the heat of the film bubble and allowing it to cool down and solidify rapidly.

[0018] A docking strip 6 is installed on each side of the temperature monitoring instrument 5. The other side of the docking strip 6 is movably inserted into the tightening block 7. A fixing rod 8 is welded to the bottom of the tightening block 7. The bottom of the fixing rod 8 is welded to the outer wall of the surface of the air ring 1.

[0019] Preferably, a sliding groove 61 is provided on the upper and lower sides of the docking strip 6, and a bayonet 62 is provided on the outer wall of the docking end of the docking strip 6 and the temperature monitoring instrument 5. A side strip 51 is fixedly installed on each side of the temperature monitoring instrument 5. The side strip 51 has a rectangular structure and its size is adapted to the internal size of the bayonet 62.

[0020] When installing the temperature monitoring instrument 5, align the two side strips 51 with the top opening of the corresponding bayonet 62, and then move the temperature monitoring instrument 5 downward so that the side strips 51 and bayonet 62 are connected. In this way, the temperature monitoring instrument 5 can be installed between the two connecting strips 6. Preferably, a support block 63 is fixedly installed at the bottom of the connecting strip 6 near the connection end with the temperature measuring instrument 5, and the arc-shaped outer wall of the support block 63 is attached to the outer wall of the bottom of the temperature measuring instrument 5.

[0021] In actual use, after installation, the arc-shaped outer wall of the support block 63 will support the bottom of the temperature monitoring instrument 5, thereby preventing the temperature monitoring instrument 5 from sliding down excessively and improving the stability of the temperature monitoring instrument 5 after it is connected to the docking strip 6.

[0022] Preferably, the tightening block 7 has an inner cavity 71, one end of the connecting strip 6 is movably inserted into the inner cavity 71, two springs 72 are symmetrically installed on the inner wall of the inner cavity 71, the outer wall of the other end of the spring 72 is connected to the outer wall of the connecting strip 6, and a limiting block 73 is fixedly installed on the upper and lower inner walls of the inner cavity 71 respectively.

[0023] In practical use, when the spring 72 pushes the mating bar 6 to reset, the mating bar 6 will drive the upper and lower sliding grooves 61 to move synchronously. In this way, the sliding grooves 61 will move against the outer wall of the corresponding limit block 73. When it reaches the maximum stroke, the limit block 73 will block the sliding groove 61, thereby preventing the mating bar 6 from disengaging from the inner cavity 71.

[0024] Preferably, the two limiting blocks 73 are movably installed in the corresponding slide grooves 61 on the side away from the inner cavity 71.

[0025] In practical use, when installing the temperature monitoring instrument 5, the side strips 51 on both sides must be precisely aligned with the corresponding slots 62 on the connecting strip 6. During the insertion process, attention should be paid to the insertion angle and depth of the side strips 51 to ensure a tight fit. At the same time, the bottom of the temperature monitoring instrument 5 should be stably placed on the corresponding support block 63. The surface of the support block 63 is treated with anti-slip material to effectively prevent the equipment from shifting during operation.

[0026] After the temperature monitor 5 and the docking strip 6 complete the initial docking, the spring 72 inside the inner cavity 71 begins to function. The spring 72 automatically resets after being compressed, using its elastic potential energy to push the docking strip 6 slowly towards the temperature monitor 5. As the docking strip 6 moves, the two docking strips 6 gradually clamp and fix the temperature monitor 5, forming a stable installation structure.

[0027] After installation and fixing, the temperature probe 4 needs to be adjusted. The temperature probe 4 is installed on the back of the temperature monitoring instrument 5 and has a rotating adjustment structure, which can be adjusted according to actual needs. Adjust the temperature probe 4 into the temperature measuring port 3. When adjusting, ensure that the sensing surface of the temperature probe 4 is facing the outer wall of the air ring 1 to ensure accurate temperature data collection.

[0028] During equipment operation, the temperature probe 4 continuously and in real time collects temperature data of the outer wall of the air ring 1 through the temperature measuring port 3. This data is transmitted in the form of electrical signals to the processing module inside the temperature monitoring instrument 5. After data processing and analysis, the data is finally displayed intuitively on the display of the temperature monitoring instrument 5.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
