Description

Technical Field

[0001] The utility model relates to the technical field of profile protection film coating, in particular to a profile protection film coating device. Background Art

[0002] In the profile processing industry, the application of protective film to the profile is an important process, which is used to protect the surface of the profile from scratches and corrosion. Before applying the protective film, it is crucial to thoroughly clean the surface of the profile to prevent impurities on it from being sandwiched between the protective film and the profile, causing problems such as bubbles, unevenness or poor adhesion, thereby affecting the protective effect and aesthetics of the protective film.

[0003] Traditional profile protective film coating equipment does not have the function of cleaning dust and impurities on the surface of the material during coating. It is usually cleaned manually, which not only reduces the coating efficiency but also easily leads to incomplete cleaning, resulting in bubbles, unevenness or poor adhesion during coating. Therefore, we have proposed a profile protective film coating equipment to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art in that the surface of the profile is manually cleaned, which not only leads to low coating efficiency but also easily causes incomplete cleaning, resulting in bubbles, unevenness or poor adhesion during coating, and to propose a coating device for a profile protective film.

[0007] A cleaning component is provided inside the cleaning box and is used to clean the profiles;

[0008] Two sets of limit assemblies are provided on the cleaning box, and the two sets of limit assemblies are located on both sides of the cleaning assembly, which are used to limit the position of the profile and cooperate with the cleaning assembly to complete the cleaning;

[0009] The drying component is arranged on the top of the drying box and is used to quickly dry the coated profiles.

[0010] In one possible design, the cleaning assembly includes two baffles, both of which are fixedly arranged on the top inner wall of the cleaning box, and the two baffles are located on both sides of the first opening. The interior of the cleaning box is rotatably connected to two transmission Kuns between the two baffles, and the outer walls of the two transmission Kuns are provided with soft brushes for cleaning. A drive assembly is provided on one side of the cleaning box.

[0011] In one possible design, the drive assembly includes a protective shell, which is fixedly arranged on one side of the base. A motor is fixedly arranged inside the protective shell. One end of two transmission Kuns extends into the interior of the protective shell. A driven gear is fixedly sleeved on the transmission Kuns. A driving gear is fixedly sleeved on the output end of the motor, and the driving gear is meshed with the two driven gears.

[0012] In a possible design, the limit assembly includes a fixing frame, which is fixedly arranged on the top of the cleaning box, and limit openings are provided on both sides of the fixing frame, and the same first limit frame is slidably connected in the two limit openings, and the first limit frame slides and extends into the cleaning box, and clearance openings are provided on both sides of the first limit frame, and sliders are slidably connected in the two clearance openings, and springs are fixedly provided on the bottom inner walls of the two clearance openings, and the top ends of the two springs are fixedly connected to the bottoms of the corresponding sliders, and the two sliders are rotatably connected to the same first limit Kun, and the top thread of the fixing frame is penetrated by a first screw, and the bottom of the first screw is rotatably connected to the top of the first limit frame.

By rotating the first screw, the first screw drives the first limit frame to move up and down to adapt to profiles of different thicknesses. At the same time, the first limit Kun on the fixed frame fits the profile and drives the surface of the profile to contact the two transmission Kun soft brushes. Then the motor in the protective shell is started, and the two transmission Kuns are driven to rotate through the active gear thereon, so that the soft brushes of the two transmission Kuns clean the surface of the profile. During the process, the vacuum cleaners installed on the top of the two fixed frames are started at the same time, and the dust and impurities generated by cleaning are sucked away by the vacuum cleaners to keep the inside of the cleaning box clean.

[0018] The cleaned profile enters the drying box and is located between the two third limit Kuns and the second limit Kuns. The two second limit Kuns adjust their positions through the second screws on them to adapt to profiles of different thicknesses. Then, multiple nozzles located between the two third limit Kuns apply a protective film to the profile.

[0019] During the coating process, the heating block in the drying box is continuously heated, and the two fans inside blow the heat evenly to the surface of the profile to achieve rapid drying. The profile that has completed coating and drying is removed from the drying box through the opening and wound up by the winding machine, finally completing the entire coating process.

The transmission Kun 13 is located between the two baffles 12 and is driven to rotate by the motor 11. The motor 11 is installed in the protective shell 10, and is engaged with the driven gears on the two transmission Kuns 13 through the driving gear, thereby driving the transmission Kun 13 to rotate. The outer wall of the transmission Kun 13 is provided with a soft brush for cleaning impurities on the surface of the profile during rotation.

[0033] To ensure the profile maintains a stable position during cleaning, the cleaning box 4 is equipped with two sets of position-limiting assemblies. Each position-limiting assembly comprises a fixed frame 7, a first position-limiting frame 15, a first position-limiting ring 16, a slider, a spring 17, and a first screw 14. The fixed frame 7 is fixed to the top of the cleaning box 4. The first position-limiting frame 15 slides within the position-limiting opening of the fixed frame 7 via a slider, with downward pressure provided by the spring 17, ensuring that the first position-limiting ring 16 maintains close contact with the profile surface. The first screw 14 is used to adjust the position of the first position-limiting frame 15 to accommodate the thickness of the profile.
