Description

Technical Field

[0001] This utility model relates to the field of film production, specifically to an online cutting and dust collection device for PET film. Background Technology

[0002] In the production of biaxially oriented polyester film, film cutting is an indispensable process. During the cutting process, tiny particles from the film edge fall off due to mechanical friction or thermal effects, forming dust. The amount of dust may increase, especially during high-speed cutting or on uneven surfaces. Therefore, dust generation is unavoidable during the cutting process. These fine dust particles often adhere to the surface of the finished film, causing defective products and reducing productivity. Therefore, reducing or eliminating dust is an issue we cannot avoid. Utility Model Content

[0003] This invention provides an online PET film cutting and dust collection device, which can remove the dust generated during film cutting.

[0004] The technical solution to achieve the above objectives is as follows:

[0005] A PET film online cutting and dust collection device includes a cutting mechanism for cutting the film, a dust collector, and dust collection guide components disposed on both sides of the film. The dust collection guide components are connected to the dust collector. The dust collection guide components include a housing, a guide plate, a guide tube, and a first driver. The housing is provided with an opening and an outlet. The guide plate is engaged with the opening. After the guide plate is fixed to the housing, an angle is formed between the guide plate and the housing. One end of the guide tube is engaged with the outlet and then fixed to the housing. The other end of the guide tube is connected to the dust collector. The first driver is fixed to the housing.

[0006] Furthermore, the cutting mechanism includes a driver, a tool holder, and a cutter. The tool holder includes two mounting plates, each of which includes a connecting plate and a pressure plate. The connecting plate is fixed to the power output end of the driver, one end of the pressure plate is fixed to the connecting plate, and the cutter is located between the two pressure plates and is fixed to the pressure plates.

[0007] Furthermore, the end face of the pressure plate facing the film is an arc-shaped surface.

[0008] Furthermore, it also includes a stud and a nut. One end of the stud is fixed to one of the pressure plates. The cutter has a first through hole, and the other pressure plate has a second through hole. After the stud passes through the first through hole on the cutter and the second through hole on the pressure plate and is threaded to the nut, the two pressure plates are locked together by the nut and the stud, and the cutter is clamped between the two pressure plates.

[0009] When this invention is in operation, the vacuum cleaner is started, and the negative pressure generated by the vacuum cleaner is applied to the part of the film being cut by the cutting mechanism through the dust suction guide component. That is, there will be a negative pressure at the part of the film being cut by the cutting mechanism. When the cutting mechanism cuts the film and generates dust, the dust is sucked into the dust suction guide component under the action of negative pressure and finally enters the vacuum cleaner. This avoids dust adhering to the surface of the finished film and ensures the quality of the film. Attached Figure Description

[0018] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0022] like Figures 1 to 5 As shown, the PET film online cutting and dust collection device of this utility model includes a cutting mechanism, a dust collector 10, and dust collection guide components disposed on both sides of the film. By distributing the dust collection guide components on both sides of the film, the film can be subjected to balanced force when both sides generate suction on the cutting area. The following is a detailed description of each part and the relationship between them.

[0023] The cutting mechanism cuts the film and includes a driver 1, a blade holder, and a cutter 2. The blade holder includes two mounting plates. The driver 1 uses linear drive components such as cylinders, hydraulic cylinders, and electric lead screws. In this invention, a cylinder is preferred for the driver 1. Each clamping plate includes a connecting plate 3 and a pressure plate 4. The connecting plate 3 is preferably fixed to the power output end of the driver 1 by fasteners. After one end of the pressure plate 4 is fixed to the connecting plate 3, a 90° angle is formed between the pressure plate 4 and the connecting plate 3. The cutter 2 is located between the two pressure plates 4 and is fixed to the pressure plates 4. When the piston rod of the driver 1 extends, the driver 1 drives the blade holder to move linearly, and the cutter 2 follows the blade holder to feed towards the film, eventually pushing the cutter 2 to the working position for cutting the film. When the piston rod of the driver 1 retracts, the driver 1 drives the blade holder to move linearly, causing the cutter 2 to follow the blade holder to move away from the film.

[0024] Since the cutter 2 needs to pass through the film when cutting the film, in order to avoid interference between the pressure plate 4 and the film, the end face of the pressure plate 4 facing the film is an arc-shaped surface. This can prevent the end face of the pressure plate 4 from touching the film, thereby preventing the cutter 4 from scratching the film.

[0025] The cutting mechanism also includes a stud 5 and a nut. One end of the stud 5 is fixed to one of the pressure plates 4. The cutter 2 has a first through hole, and the other pressure plate 4 has a second through hole. After the stud 5 passes through the first through hole on the cutter 2 and the second through hole on the pressure plate 4 and is threadedly connected to the nut, the two pressure plates 4 are locked together by the nut and the stud 5, and the cutter 2 is clamped between the two pressure plates 4.

[0026] There are two studs 5, which are arranged at different heights. After the studs 5 pass through the cutter 2, the two studs 5 can prevent the cutter 2 from rotating and protect the cutter 2 from tilting.

[0027] The vacuum cleaner 10 includes a container 10a, a support 10b, a hose 10c, a housing 10d, an air pump (not shown), a handle 10e, and casters 10f. The container 10a is supported by the support 10b and fixed to the support 10b. One end of the hose 10c is connected to the container 10a, and the other end of the hose 10c passes through the housing 10d and connects to the air pump. The air pump is fixed to the support 10b, and the housing 10d covers the air pump and is fixed to the support 10b. The handle 10e is fixed to the housing 10d. Casters 10f are installed at the bottom of the support 10b, and at least two of the casters 10f are casters with locking mechanisms. This type of caster is existing technology and will not be described in detail here. Applying a pushing force to the handle can move the vacuum cleaner 10.

[0028] Because of the thinness of the film, if the suction force generated by the vacuum cleaner 10 and the suction guide assembly is too large, it may cause the film to deform. Therefore, a pressure gauge 10g is also installed on the top of the container 10a. The pressure gauge 10g detects the pressure inside the container 10a, which allows the user to adjust the suction force of the current air pump to achieve the purpose of both vacuuming and avoiding deformation of the film.

[0029] The vacuum guide assembly is connected to the vacuum cleaner 10. The vacuum guide assembly includes a housing 11, a guide plate 12, a guide tube 13, and a first driver 14. The housing 11 is provided with an opening 11a and an outlet 11b. The guide plate 12 cooperates with the opening 11a. After the guide plate 12 is fixed to the housing 11, an angle is formed between the guide plate 12 and the housing 11, that is, the guide plate 12 is inclined to the housing 11. There are two guide plates 12, which are arranged symmetrically. An airflow channel is formed between the two guide plates 12. Obviously, the area of ​​the airflow channel is smaller than the area of ​​the opening 11a. According to the pressure formula, the suction pressure generated at the airflow channel is greater than the suction pressure generated at the opening 11a. This allows the use of a low-power vacuum pump.

[0030] After one end of the guide tube 13 is engaged with the output port 11b, the guide tube 13 is fixed to the cover 11. The other end of the guide tube 13 is connected to the container 10a in the vacuum cleaner 10. The first driver 14 is fixed to the cover 11. The first driver 14 can be a linear drive component such as a cylinder, hydraulic cylinder, or electric lead screw. In this utility model, the first driver 14 is preferably a cylinder.
