Description

Technical Field

[0001] This utility model relates to the field of BOPET production technology, and in particular to an online dust removal device for BOPET production. Background Technology

[0002] In the production of BOPET (biaxially oriented polyethylene terephthalate) film, the cleanliness of the film surface is a core indicator determining product quality. BOPET film is widely used in high-end fields such as food packaging, electronic components, and optical materials. If dust, fibers, or other impurities adhere to its surface, it can lead to defects such as pinholes, bubbles, and uneven coating in subsequent processes (e.g., coating, lamination, and printing), and in severe cases, directly cause product scrap (statistics show that the failure rate of BOPET film due to surface contamination can reach 5% to 10%). Existing online dust removal devices in BOPET production have significant technical limitations in terms of dust removal efficiency, adaptability, and operational stability, making it difficult to meet the demands of high-precision production.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: during the production process, the film adsorbs dust from the environment, which leads to defects in subsequent production processes and causes the finished film to be unqualified. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the existing technology, the film adsorbs dust in the environment during the production process, which leads to defects in subsequent production processes and results in unqualified finished film products. To address this, we propose an online dust removal device for BOPET production.

[0005] To achieve the above objectives, this application adopts the following technical solution: an online dust removal device for BOPET production, comprising a processing machine, with fixtures installed on both sides of the processing machine, and a dust-shielding chamber and a dust-shielding plate respectively threadedly connected inside the two fixtures. The surface of the dust-shielding plate is slidably connected to the dust-shielding chamber, and a dust-driving device is provided on the surface of the dust-shielding chamber. The dust-driving device includes a fixed frame, which is fixedly connected to the surface of the dust-shielding chamber. A rotating rod is fixedly connected inside the fixed frame, and a disc is rotatably connected to the arc surface of the rotating rod. A fan is fixedly connected to one side of the disc. A fixed rod is fixedly connected to the surface of the dust-shielding chamber, and an operating plate is slidably connected to the arc surface of the fixed rod. A plug rod is fixedly connected to one side of the operating plate, and several slots are provided on the surface of the dust-shielding plate.

[0006] Preferably, one end of the fixing rod is fixedly connected to a limiting plate, and the size of the insertion rod is adapted to the size of the dust cover slot.

[0007] Preferably, a first spring is fitted onto the arc surface of the fixing rod, and the two ends of the first spring are fixedly connected to the operating plate and the dust cover, respectively.

[0008] Preferably, a rubber ring is slidably connected to the arc surface of the fixing rod, and the rubber ring is fixedly connected to the surface of the operating plate.

[0009] Preferably, the rotating rod is provided with adjustment devices at both ends. The adjustment devices include two strip plates, which are fixedly connected to both ends of the rotating rod respectively. A drive rod is threaded into the strip plate. An adjustment block is rotatably connected to one end of the drive rod. Several square slots are provided on both sides of the disc.

[0010] Preferably, an anti-slip pad is fixedly connected to one side of the adjusting block, and the size of the anti-slip pad is adapted to the size of the square groove.

[0011] Preferably, a positioning rod is fixedly connected to one side of the adjusting block, and the arc surface of the positioning rod is slidably connected to the strip plate.

[0012] The technical effects and advantages of this utility model are as follows: 1. In this utility model, by setting up a dust removal device, the effect of wind-powered dust removal of the film during the production process is achieved. At the same time, the dust shield can be adjusted according to the production size of the processing machine, which is convenient for use with different models of processing machines. This avoids the film adsorbing dust in the environment during the production process, which could lead to defects in subsequent production processes and result in unqualified finished film products, thus improving the practicality of the device.

[0013] 2. In this utility model, by setting an adjustment device, the air outlet angle of the fan can be adjusted, which avoids the situation where the position of the fan is too fixed, making it difficult to meet the needs of dust removal at different positions of the film, thus making it difficult to completely remove dust from the film and reducing the dust removal effect, thereby improving the convenience of the device.

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0017] Reference Figure 1 As shown, this utility model provides a technical solution: an online dust removal device for BOPET production, including a processing machine 1. Fixers 2 are installed on both sides of the processing machine 1. Dust-shielding chambers 4 and dust-shielding plates 3 are threadedly connected to the two fixtures 2 respectively. The surface of the dust-shielding plate 3 is slidably connected to the dust-shielding chamber 4. A dust-removing device 5 is provided on the surface of the dust-shielding chamber 4. By setting the dust-removing device 5, the effect of wind-driven dust removal of the film during the production process is achieved. Simultaneously, the dust-shielding plate 3 can be adjusted according to the production size of the processing machine 1, facilitating the use of different models of processing machines 1. This avoids the film adsorbing dust from the environment during production, preventing defects in subsequent production processes and resulting in unqualified finished film products, thus improving the practicality of the device. Adjustment devices 6 are provided at both ends of the rotating rod 502. By setting the adjustment devices 6, the air outlet angle of the fan 504 can be adjusted, avoiding the fan 504 being too fixed in position, making it difficult to meet the dust removal needs of different positions on the film, thus preventing incomplete dust removal of the film and reducing the dust removal effect, thereby improving the convenience of the device.

[0018] The specific setup and function of its dust removal device 5 and adjustment device 6 will be explained below.

[0019] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the dust removal device 5 includes a fixed frame 501, which is fixedly connected to the surface of the dust-covering chamber 4. A rotating rod 502 is fixedly connected inside the fixed frame 501. A disc 503 is rotatably connected to the arc surface of the rotating rod 502. A fan 504 is fixedly connected to one side of the disc 503. A fixed rod 505 is fixedly connected to the surface of the dust-covering chamber 4. An operating plate 506 is slidably connected to the arc surface of the fixed rod 505. An insertion rod 507 is fixedly connected to one side of the operating plate 506. Several slots are provided on the surface of the dust-covering plate 3. A limiting plate 508 is fixedly connected to one end of the fixed rod 505. The size of the insertion rod 507 is adapted to the size of the slots in the dust-covering plate 3. The limiting plate 508 achieves the effect of limiting the maximum sliding distance of the operating plate 506 on the arc surface of the fixed rod 505, thus preventing workers from being injured. When the operating plate 506 is pulled, if the pulling force is too great, the operating plate 506 may detach from the arc surface of the fixing rod 505. The arc surface of the fixing rod 505 is fitted with a first spring 509. The two ends of the first spring 509 are fixedly connected to the operating plate 506 and the dust cover 4, respectively. The first spring 509 achieves the effect of automatically inserting the insertion rod 507 into the slot of the dust cover 3, and at the same time improves the stability of the insertion rod 507 when limiting the dust cover 3. The arc surface of the fixing rod 505 is slidably connected with a rubber ring 510. The rubber ring 510 is fixedly connected to the surface of the operating plate 506. The elasticity of the rubber ring 510 wraps around the arc surface of the fixing rod 505, thereby slowing down the sliding speed of the operating plate 506 on the arc surface of the fixing rod 505, reducing the impact of external shaking on the operating plate 506, and playing a damping role.

[0020] Reference Figure 5 As shown, specifically, the adjusting device 6 includes two strip plates 61, which are fixedly connected to both ends of the rotating rod 502. A driving rod 62 is threaded into the strip plate 61, and an adjusting block 63 is rotatably connected to one end of the driving rod 62. Several square slots 64 are opened on both sides of the disc 503. An anti-slip pad 65 is fixedly connected to one side of the adjusting block 63. The size of the anti-slip pad 65 is adapted to the size of the square slot 64. The anti-slip pad 65 achieves the effect of increasing the stability of the fan 504. A positioning rod 66 is fixedly connected to one side of the adjusting block 63. The arc surface of the positioning rod 66 is slidably connected to the strip plate 61. The positioning rod 66 achieves the effect of restricting the adjusting block 63 from rotating with the driving rod 62, so that the adjusting block 63 can be quickly and accurately inserted into the square slot 64.

[0021] Working principle: Inside the fixing frame 501 on the surface of the dust-covering chamber 4, the disc 503 on the rotating rod 502 drives the fan 504 to rotate, which can blow dust off the surface of the dust-covering plate 3 (which works with the dust-covering chamber 4 to prevent dust). The film after dust removal is blocked by the dust-covering plate 3 to prevent dust from falling back. When it is necessary to fix the dust-covering plate 3, the operating plate 506 on the fixing rod 505 (fixed to the dust-covering chamber 4) drives the insertion rod 507 to automatically insert into the slot of the dust-covering plate 3 under the elastic force of the first spring 509 (the two ends of which are respectively connected to the operating plate 506 and the dust-covering chamber 4). The limit is completed to prevent the dust cover 3 from shaking; the limiting plate 508 at one end of the fixed rod 505 prevents the operating plate 506 from detaching from the arc surface of the fixed rod 505; the rubber ring 510 (fixed to the operating plate 506) wraps around the fixed rod 505 with elasticity, slowing down the sliding speed of the operating plate 506 on the arc surface of the fixed rod 505, reducing the impact of external shaking on the operating plate 506, and playing a damping effect. When the dust cover 3 needs to be adjusted, the operating plate 506 is pulled to overcome the elastic force of the first spring 509, so that the insertion rod 507 can be disengaged from the slot of the dust cover 3.

[0022] Rotating the drive rod 62 inside the strip plate 61 pushes the adjusting block 63 closer to the disc 503 (connected to the fan 504). The positioning rod 66 (fixed to the adjusting block 63) slides along the strip plate 61, restricting the adjusting block 63 from rotating with the drive rod 62. This ensures that the anti-slip pad 65 on one side of the adjusting block 63 (its size is adapted to the square grooves 64 on both sides of the disc 503) is accurately inserted into the corresponding square groove 64, thus fixing the angle of the fan 504. By selecting different square grooves 64, the blowing direction of the fan 504 can be adjusted, enhancing the dust removal effect on different areas of the dust shield 3. The anti-slip pad 65 increases the stability of the fixation and prevents the angle of the fan 504 from shifting during operation. The two work together to achieve basic dust protection through the dust shield 3 and actively remove dust with the help of the adjustable fan 504, thereby improving the overall dust protection effect of the device.

[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
