Description

Technical Field

[0001] This utility model relates to the field of PET film technology, and more specifically, to a high-efficiency PET frosting effect processing machine. Background Technology

[0002] PET is divided into fiber-grade polyester chips and non-fiber-grade polyester chips. Fiber-grade polyester is used to manufacture polyester staple fiber and polyester filament, and is the raw material supplied to polyester fiber companies for processing fibers and related products. Polyester is the largest variety of chemical fiber in terms of output. Non-fiber-grade polyester also has applications such as bottles and films, and is widely used in the packaging industry, electronics, medical and health care, construction, automobile and other fields.

[0003] During the production of PET films, surface roughening is often required to meet specific processing needs. This treatment creates a certain degree of roughness on the PET film surface, thereby improving its frictional and optical properties. Currently, the most common roughening method is sandblasting. Sandblasting uses a high-speed airflow to propel abrasive particles onto the PET film surface. Through the impact and friction of the abrasive particles, a roughened effect is achieved on the film surface.

[0004] Sandblasting PET film often generates a large amount of dust. This dust not only pollutes the working environment and surrounding area but can also harm the health of operators. Especially in some traditional sandblasting equipment, the lack of effective dust control measures often allows dust to diffuse into the air, leading to environmental pollution problems. Currently, no effective solution has been proposed to address these technical issues. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a high-efficiency PET frosting effect processing machine to overcome the above-mentioned technical problems existing in the existing related technologies.

[0024] 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.

[0025] According to an embodiment of the present invention, a high-efficiency PET frosting effect processing machine is provided.

[0026] Example 1

[0027] like Figures 1-4As shown, the high-efficiency PET frosted effect processing machine according to an embodiment of the present invention includes a worktable 1, a feeding roller 2 on the worktable 1, a support frame 3 on one side of the feeding roller 2, a connecting frame 4 at the top inside the support frame 3, a nozzle 5 fixedly connected to the connecting frame 4, openings 6 at both ends of the support frame 3, an upper baffle 7 inside the openings 6, a fixing frame 8 on one side of the upper baffle 7, the fixing frame 8 being fixedly connected to the support frame 3, a threaded rod 9 connected to the fixing frame 8 via a bearing, a slider 10 threadedly connected to the threaded rod 9, the slider 10 being connected to the upper baffle 7, and one end of the threaded rod 9 passing through the fixing frame 3. The fixed frame 8 is connected to the drive motor 11, the support frame 3 is fixedly connected to the workbench 1, the lower baffle 12 is provided below the upper baffle 7, and the lower baffle 12 is connected to the support frame 3 by bolts. The connecting frame 4 has dust suction ports 15 on both sides, and the dust suction ports 15 are connected to the dust suction pipe 16. The dust suction pipe 16 is connected to the collection box 18 through the connecting pipe 17. The collection box 18 has an exhaust fan 19 on one side, and the exhaust fan 19 is connected to the collection box 18 through the exhaust pipe 20. A filter screen is provided at the connection between the exhaust pipe 20 and the collection box 18. The support frame 3 has an observation window 28 on one side for observing the sandblasting process. With the above solution, when the PET film needs to be sandblasted, the drive motor 11 is started to drive the threaded rod 9 to rotate. The rotation of the threaded rod 9 drives the slider 10 to move, thereby moving the upper baffle 7 upward, which facilitates the laying of the film by the workers. After the laying is completed, the drive motor 11 can be started to reverse, which moves the upper baffle 7 downward, making the opening 6 smaller and reducing the possibility of dust leakage from the opening 6 during the sandblasting process. During the sandblasting process, the exhaust fan 19 is started. The exhaust pipe 20 is connected to the collection box 18, and the collected dust can be transported to the collection box 18 through the dust suction port 15, the dust suction pipe 16 and the connecting pipe 17. A filter screen is also installed at the connection between the collection box 18 and the exhaust pipe 20 to filter the collected dust and prevent the dust from spreading into the air through the exhaust fan 19.

[0028] like Figures 1-4As shown, nozzle 5 is connected to conveying pipe 13, which is connected to a storage hopper (not shown in the figure). The abrasive in the storage hopper can be supplied with high-pressure gas by an air compressor. This high-pressure gas is transported to the storage hopper through a pipeline and mixes with the abrasive in the storage hopper. Due to the action of the high-pressure gas, the abrasive is pushed and moves along the conveying pipe 13 toward nozzle 5. When the abrasive reaches the nozzle 5, it will be propelled by high-pressure gas and ejected at high speed from the nozzle 5, impacting the surface of the PET film to achieve a sanding process. The connecting frame 4 is connected to the hydraulic telescopic rod 14, which is located at the top of the support frame 3. The feeding roller 2 has a first fixed plate 21 on both sides, which is fixedly connected to the worktable 1. The support frame 3 has a first guide roller 25 rotatably connected inside, and a second guide roller 26 on both sides. The two ends of the second guide roller 26 are rotatably connected to the mounting plate 27, which is fixedly connected to the worktable 1. The worktable 1 has a second fixed plate 22 at one end, and there are two second fixed plates 22. A take-up roller 23 is located between the two second fixed plates 22, and one end of the take-up roller 23 passes through the second fixed plate 22 and is connected to the output end of the servo motor 24. Through the above scheme, when sandblasting the PET film, the first guide roller 25 and the second guide roller 26 guide the PET film, helping the PET film to remain straight throughout the processing, reducing the risk of damage caused by friction. Furthermore, the film is wound up by the take-up roller 23, which is driven by the servo motor 24, ensuring the smooth transmission of the PET film throughout the processing. It also ensures that the film maintains appropriate tension during processing, avoiding wrinkles or stretching deformation, thereby improving the stability of product quality.

[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, and by setting the threaded rod 9, the slider 10, and the drive motor 11, the position of the upper baffle 7 can be adjusted according to the thickness of the PET film, preventing dust from spreading from both sides due to the excessively large openings 6 on both sides of the support frame 3. Furthermore, by setting dust suction ports 15 on both sides of the connecting frame 4 and connecting them to the collection box 18 through the dust suction pipe 16, the dust generated during the sandblasting process can be effectively collected, further preventing dust from spreading into the air and reducing environmental pollution. Moreover, by connecting the connecting frame 4 to the hydraulic telescopic rod 14 and placing it at the top of the support frame 3, the height of the nozzle 5 can be precisely adjusted to meet different processing requirements, thereby improving the accuracy and flexibility of nozzle 5 adjustment.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
