Description

Technical Field

[0001] This utility model relates to the field of film processing technology, and in particular to an oiling device for PET film production. Background Technology

[0002] PET film, with its excellent physical properties, chemical stability, and high transparency, has been widely used in many fields such as food packaging, electronics, and pharmaceuticals. During the production of PET film, oiling is a crucial step in further optimizing its surface properties, such as enhancing its non-stick and slip properties, to meet the specific needs of different applications.

[0003] Traditional oiling methods, such as spray coating, while meeting basic oiling requirements to some extent, still have some significant problems. During spray coating, some lubricating oil may be dispersed into the air in a mist form, leading to resource waste and potential environmental pollution. Furthermore, after spray coating, the PET film often shifts during the winding process back onto the rollers. This is due to changes in friction between the film and the rollers during oiling, or uneven tension distribution of the film after coating. This shift not only negatively impacts subsequent processing and use of the film but can also damage production equipment, ultimately reducing production efficiency.

[0004] Therefore, we need to design an oiling equipment for PET film production. Utility Model Content

[0005] To overcome the drawbacks of lubricating oil being easily atomized and scattered during spray coating, resulting in resource waste, and the PET film being prone to positional displacement during the winding process of the roller, this utility model provides an oiling device for PET film production.

[0006] A coating device for PET film production includes a base, a support platform, connecting plates, a storage frame, a cover plate, a coating roller, a mounting platform, a motor, and a pulley assembly. The base has a support platform, and connecting plates are symmetrically arranged at the top center of the support platform. A storage frame is located between the upper parts of the connecting plates. The coating roller is rotatably arranged between the lower parts of the two connecting plates. The mounting platform is located inside the base, and the motor is mounted on the mounting platform. A pulley assembly is connected between the output end of the motor and the front end of the coating roller. The device also includes a coating positioning assembly, which is located on the support platform.

[0007] Furthermore, the application positioning component includes a positioning block and an application roller two. The positioning blocks are symmetrically arranged on the front and back of the top right side of the support platform, and each positioning block has a limit opening. The application roller two is located on the lower right side of the storage frame, and the application roller two is located to the right of the application roller one.

[0008] Furthermore, it also includes a placement cylinder and fasteners. The placement cylinder is provided on the left side of the support platform, and the front end of the placement cylinder is provided with fasteners via threads.

[0009] Furthermore, it also includes a second motor and a take-up drum. The second motor is installed on the right rear side of the top of the support platform. The output end of the second motor is equipped with a take-up drum, and the front end of the take-up drum is also connected to a fastener by a thread.

[0010] Furthermore, it also includes an auxiliary roller, which is rotatably mounted on the left side of the support platform, with a certain gap between the auxiliary roller and the support platform.

[0011] Furthermore, it also includes a cover plate, which is provided on the top of the storage frame.

[0012] The beneficial effects and significant advancements of this utility model are as follows:

[0013] This invention, through the design of positioning blocks and coating rollers, ensures that lubricating oil is applied evenly and stably to the PET film. This design optimizes the oiling process, avoids problems such as uneven oil film thickness and waste, thereby improving the oiling quality of the PET film. Through the design of positioning blocks, the PET film can be accurately positioned and fixed during the winding process, effectively preventing it from shifting on the high-speed rotating winding drum. This not only ensures the uniformity of the oiling effect, but also improves production efficiency and product quality. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example: An oiling device for PET film production. Please see below. Figures 1 to 3As shown, the system includes a base 1, a support platform 2, a connecting plate 3, a storage frame 4, a cover plate 5, an applicator roller 6, a mounting platform 7, a motor 8, a pulley assembly 9, a placement cylinder 10, fasteners 11, a second motor 12, a take-up cylinder 13, a positioning block 14, an applicator roller 15, and an auxiliary roller 16. The base 1 provides the supporting foundation for the entire equipment. The support platform 2 is connected to the top of the base 1. The connecting plate 3 is symmetrically connected to the top center of the support platform 2. The upper part of the connecting plate 3 is connected to the storage frame 4, which is used to store oil. The top of the storage frame 4 is covered with a cover plate 5 to prevent dust and impurities from entering, ensuring the purity of the oil. Between the lower parts of the two connecting plates 3... A coating roller 6 is rotatably connected to the base 1, which evenly applies lubricating oil to the PET film by rotating. A mounting platform 7 is connected to the bottom of the base 1, and a motor 8 is mounted on the top of the mounting platform 7. A square opening is provided on the front side of the top of the support platform 2. A pulley assembly 9 is connected between the output shaft of the motor 8 and the front end of the coating roller 6. The motor 8 drives the pulley assembly 9, thereby driving the coating roller 6 to rotate, achieving automated oil application. The pulley assembly 9 is located within the square opening and consists of two pulleys and a flat belt. The two pulleys are respectively connected to the output shaft of the motor 8 and the front end of the coating roller 6, while the flat belt is fitted over the two pulleys. On the left side of the support platform 2, a placement cylinder 10 is provided for holding uncoated PET film, facilitating its removal for coating. A fastener 11 is threadedly connected to the front end of the placement cylinder 10 to prevent the PET film from slipping off during rotation. A motor 12 is installed on the rear right side of the top of the support platform 2. The output shaft of the motor 12 is connected to a winding drum 13, which collects the coated PET film for subsequent processing and use. The front end of the winding drum 13 is also threadedly connected to a fastener 11. Positioning blocks 14 are symmetrically connected to the front and rear of the top right side of the support platform 2. Each positioning block 14 has a limit opening for... The PET film is positioned to prevent it from shifting during winding. Two positioning blocks 14 are located to the left of the winding drum 13. A second coating roller 15 is connected to the lower right side of the storage frame 4. The second coating roller 15 is located to the right of the first coating roller 6. The second coating roller 15 can further ensure that the PET film is evenly coated. An auxiliary roller 16 is rotatably connected to the left side of the support platform 2. A certain gap is left between the auxiliary roller 16 and the support platform 2 to facilitate the passage of the PET film. The auxiliary roller 16 is located to the right of the placement drum 10. The auxiliary roller 16 provides additional support and guidance for the PET film to ensure that it passes smoothly during the coating process.

[0020] When using the coating equipment for PET film production, first turn on the power to motor 8. After motor 8 starts, it will drive the pulley assembly 9, which in turn will cause the coating roller 6 to start rotating.

[0021] Next, the uncoated PET film is drawn from the placement cylinder 10. Ensure one end of the PET film passes through the limiting opening on the positioning block 14 to position the PET film and prevent it from shifting during subsequent processes. Then, allow the PET film to pass over the auxiliary roller 16; this step provides additional support and guidance for the PET film, ensuring its smooth passage.

[0022] Subsequently, the PET film will pass through coating roller 6 and coating roller 15 in sequence. Under the action of coating roller 6 and coating roller 15, lubricating oil will be evenly applied to the PET film.

[0023] After the PET film is led out and its path is ensured to be correct, fasteners 11 are used to secure the PET film to the placement drum 10 and the take-up drum 13 respectively. This is to prevent the PET film from slipping off the placement drum 10 and the take-up drum 13 during rotation, ensuring the smooth progress of the oiling and winding process.

[0024] Next, start motor 12. After motor 12 starts, it will drive take-up drum 13 to start rotating, thereby starting to collect the oiled PET film.

[0025] During the oiling and winding process, the condition of the PET film needs to be continuously monitored. Ensure that it passes smoothly during oiling without any deviation, breakage, or uneven lubrication.

[0026] When the PET film on the take-up drum 13 has been collected to a certain length, turn off motor 12 to stop the winding operation. Then, use scissors or other tools to cut the PET film off the take-up drum 13 and remove it from the equipment.

[0027] Finally, turn off motor 8 to stop the rotation of applicator roller 6. This completes the entire oiling process.
