Description

Technical Field

[0001] This utility model relates to the field of thin film processing technology, and in particular to an air purification and extraction device for thin film processing. Background Technology

[0002] In film coating, slitting, and laminating production lines, material handling processes generate dust, debris, and volatile waste gases. These pollutants not only adhere to the film surface, causing appearance defects, deteriorating barrier properties and mechanical strength, and reducing yield, but also pollute the production environment and threaten the health of operators.

[0003] To address the aforementioned issues, existing technologies typically employ dust collection devices (usually composed of a fan, exhaust duct, and ventilation duct) to collect and treat pollutants. However, these devices still suffer from the following key drawbacks: existing devices are mostly single-stage airflow devices, which cannot adapt to different working conditions such as film thickness, processing speed, and dust volume; insufficient suction results in high dust residue and continuous pollution; and excessive suction can easily cause film wrinkles and displacement due to airflow pulling, interfering with production stability.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an air purification and extraction device for thin film processing, comprising a fixed bracket, a conveying roller for thin film conveying is provided inside the fixed bracket, a ventilator is installed on one side of the fixed bracket, the exhaust port and exhaust port of the ventilator are respectively connected to an exhaust pipe and an exhaust pipe, an exhaust hood is provided on the fixed bracket, and the exhaust pipe is connected to the exhaust hood. The exhaust duct is equipped with a wind control mechanism, which includes a wind control plate rotatably disposed inside the exhaust duct. An air adjustment handle is disposed outside the exhaust duct, and a bolt is disposed at one end of the air adjustment handle. The bolt is screwed to the air adjustment handle and the air control plate. A through hole is provided on the exhaust duct, and the bolt passes through the through hole and is screwed to the air control plate. The bolt can rotate within the through hole.

[0007] As a further embodiment of this utility model: a positioning frame is also provided on the outside of the exhaust pipe, an arc-shaped adjustment groove is provided on the positioning frame, the air adjustment handle is provided between the positioning frame and the exhaust pipe, a bolt two is provided on the side of the positioning frame away from the exhaust pipe, a screw hole is provided on the air adjustment handle, and the end of the bolt two passes through the arc-shaped adjustment groove and is screwed and fixed to the screw hole.

[0008] As a further embodiment of this utility model: a bolt three is provided on the side of the exhaust pipe away from the air regulating handle, and a through hole two is opened on the exhaust pipe. The bolt three passes through the through hole two and is screwed to the air control plate, and the bolt three can rotate within the through hole two.

[0009] As a further embodiment of this utility model: a handle is provided on the air control plate, and a waste discharge pipe is sleeved on the exhaust pipe.

[0010] As a further embodiment of this utility model: sealing rings are provided in the through holes one and two, and the two sealing rings are respectively sleeved on the outside of bolt one and bolt three.

[0011] As a further embodiment of this utility model: the lower end of the exhaust pipe is provided with several branch pipes, and all of the branch pipes are connected to the exhaust hood.

[0012] Compared with the existing technology, the beneficial effects of this technical solution are as follows: the ventilator provides the exhaust power, the exhaust hood is aimed at the film processing area, and dust, debris and volatile waste gas are captured through the exhaust pipe; the waste gas is discharged through the exhaust pipe, avoiding the adhesion of the film and affecting the quality, while purifying the production environment; By rotating the air regulating handle and connecting it to the air control plate with a bolt, the air control plate can be rotated inside the exhaust pipe, thereby changing the angle between the air control plate and the inner wall of the exhaust pipe. The smaller the angle, the narrower the flow area inside the exhaust pipe, and the greater the resistance of the fan, which reduces the suction power. Similarly, the larger the angle, the wider the flow area, and the stronger the suction power. In summary, this technical solution, by adjusting the suction power, can adapt the suction power during exhaust gas absorption and emission to different operating conditions, thereby avoiding situations that may affect quality and ensuring air cleanliness.

[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 1-3 An air purification and extraction device for film processing includes a fixed bracket 1, a conveying roller 2 for film conveying is provided inside the fixed bracket 1, a fan 3 is installed on one side of the fixed bracket 1, the exhaust port and exhaust port of the fan 3 are respectively connected to an exhaust pipe 4 and an exhaust pipe 5, an exhaust hood 6 is provided on the fixed bracket 1, and the exhaust pipe 4 is connected to the exhaust hood 6. An air control mechanism 7 is provided inside the exhaust pipe 5. The air control mechanism 7 includes an air control plate 71 that is rotatably installed inside the exhaust pipe 5. An air adjustment handle 72 is provided outside the exhaust pipe 5. A bolt 73 is provided at one end of the air adjustment handle 72. The bolt 73 is screwed to the air adjustment handle 72 and the air control plate 71. A through hole 51 is provided on the exhaust pipe 5. The bolt 73 passes through the through hole 51 and is screwed to the air control plate 71. The bolt 73 can rotate inside the through hole 51.

[0018] Specifically, the ventilator 3 provides the exhaust power, the exhaust hood 6 is aimed at the film processing area, and the dust, debris and volatile waste gas are captured through the exhaust pipe 4; the waste gas is discharged through the exhaust pipe 5 to avoid the film adhering and affecting the quality, and at the same time to purify the production environment. The exhaust pipe 5 discharges the waste gas to the outside of the factory area, such as the roof, and an air purification device (not shown in the figure) is installed on the roof. The air purification device is used to purify the gas before it is discharged into the external environment, thereby avoiding pollution to the external environment. By rotating the air regulating handle 72 and connecting the air regulating handle 72 and the air control plate 71 with bolt 73, the air control plate 71 can be rotated inside the exhaust pipe 5. This changes the angle between the air control plate 71 and the inner wall of the exhaust pipe 5. The smaller the angle, the narrower the flow area inside the exhaust pipe 5, and the greater the air resistance of the fan 3, thus reducing the suction power. Similarly, the larger the angle, the wider the flow area, and the stronger the suction power. In summary, this technical solution, by adjusting the suction power, can adapt the suction power during exhaust gas absorption and emission to different working conditions, so as to avoid situations that affect the quality and ensure the air cleaning effect.

[0019] Based on the above embodiments, it is further proposed that a positioning frame 8 is also provided outside the exhaust pipe 5. The positioning frame 8 has an arc-shaped adjustment groove 81. The air adjustment handle 72 is located between the positioning frame 8 and the exhaust pipe 5. The second bolt 82 is located on the side of the positioning frame 8 away from the exhaust pipe 5. The air adjustment handle 72 has a screw hole 74. The end of the second bolt 82 passes through the arc-shaped adjustment groove 81 and is screwed and fixed to the screw hole 74.

[0020] Specifically, when adjusting the wind force, loosen bolt 82 to separate it from screw hole 74, then rotate wind adjustment handle 72 to drive wind control plate 71 to rotate. At the same time, the rotation trajectory of wind adjustment handle 72 corresponds to the arc of arc adjustment groove 81. After adjusting to a suitable wind force, tighten bolt 82 to reconnect it with screw hole 74. Then, use the nut of bolt 82 to press against positioning frame 8 to fix wind adjustment handle 72 and positioning frame 8, thereby fixing the state of wind control plate 71 and preventing wind control plate 71 from rotating due to airflow impact, ensuring long-term stability of the adjusted wind force. When the air regulating handle 72 rotates from one end of the arc-shaped adjusting groove 81 to the other, this rotation angle corresponds to the air control plate 71 rotating to a vertical state within the exhaust duct 5. That is, the arc-shaped adjusting groove 81 can limit the rotation range of the air regulating handle 72, thereby limiting the maximum rotation angle of the air control plate 71. When the air control plate 71 rotates to a vertical state, it corresponds to the maximum wind force. When the air control plate 71 is in the initial state, it does not correspond to blocking the inside of the exhaust duct 5, and the rotation angle is at its minimum within the adjustment range, such as 10°. Therefore, it allows the staff to have a limited range when adjusting the wind force, making it easier to understand the current wind force level. It can also prevent the air control plate 71 from blocking the inside of the exhaust duct 5, which could cause the ventilator 3 to malfunction due to excessive wind resistance.

[0021] Based on the above embodiments, it is further proposed that a bolt 3 75 is provided on the side of the exhaust pipe 5 away from the air regulating handle 72, and a through hole 2 52 is opened on the exhaust pipe 5. The bolt 3 75 passes through the through hole 2 52 and is screwed to the air control plate 71, and the bolt 3 75 can rotate in the through hole 2 52.

[0022] Specifically, by adding bolt 375 on the other side of the air control plate 71, both ends of the air control plate 71 are fixed with anchor points, thereby improving the stability of the air control plate 71 when rotating. Among them, bolt 73 can rotate in through hole 51, and bolt 75 can rotate in through hole 52. That is, both bolt 73 and bolt 75 have a section without threads, and this section of bolt 73 and bolt 75 overlaps with through hole 51 and through hole 52 respectively, so that bolt 73 and bolt 75 can rotate in through hole 51 and through hole 52 respectively.

[0023] Based on the above embodiments, it is further proposed that the air control plate 71 is provided with a handle 76 and the exhaust pipe 53 is sleeved on the exhaust pipe 5.

[0024] Specifically, the exhaust pipe 53 fitted onto the exhaust duct 5 is used to connect to the air purification device on the roof. The exhaust pipe 53 and the exhaust duct 5 are connected in a detachable manner via a flange. The detachable connection between the exhaust pipe 53 and the exhaust duct 5 facilitates the installation of the air control plate 71 inside the exhaust duct 5. The handle 76 facilitates operation when installing the air control plate 71.

[0025] Based on the above embodiments, it is further proposed that sealing rings 54 are provided in the through holes 51 and 52, and the two sealing rings 54 are respectively sleeved on the outside of bolts 73 and 75.

[0026] Specifically, by sealing the through hole 51 and the through hole 52 with two sealing rings 54, gas leakage can be prevented.

[0027] Based on the above embodiments, it is further proposed that the lower end of the exhaust pipe 4 is provided with several branch pipes 41, and the several branch pipes 41 are all connected to the exhaust hood 6.

[0028] Specifically, several branch pipes 41 are used to expand the exhaust coverage area, thereby adapting to the planar requirements of the membrane and improving the exhaust gas extraction efficiency.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
