Description

Technical Field

[0001] The invention relates to the technical field of protective films, and in particular to a method for spraying a spray-type protective film on building doors and windows. Background Art

[0002] At present, building doors and windows are customized products with irregular sizes and thicknesses and many special shapes. As a result, existing aluminum profile doors and windows are usually packaged manually. However, manual packaging is time-consuming and difficult to provide all-round protection, which makes the products easily damaged during installation and transportation. The packaging and protection work efficiency of the doors and windows industry is low. Summary of the invention

[0003] Therefore, in response to the above-mentioned problems, the present invention proposes a method for spraying a spray-type protective film on building doors and windows, which solves the technical problems that manual packaging takes a long time, is difficult to provide all-round protection, causes products to be easily damaged during installation and transportation, and has low efficiency in packaging and protection work in the doors and windows industry.

[0004] To achieve the above object, the present invention adopts the following technical solution: a method for spraying a spray-type protective film on building doors and windows, comprising the following steps:

[0005] The first step is to clean the doors and windows that need to be sprayed to remove oil and dust, and then output them to the spraying station;

[0006] The second step is to prepare a foaming adhesive solvent, and stir 15-45% of liquid adhesive, 10-30% of a blending agent, 1-5% of putty powder, and the remaining 20-74% of the foaming adhesive solvent in a mixer for 1-5 minutes according to the above proportions, and mix them thoroughly. After completion, put them into a spray gun of a spraying device;

[0007] The third step is to adjust the spray gun pressure of the spray device to 0.3-0.5Mpa, and spray the prepared foaming glue solvent on the surface of the building doors and windows, with the thickness controlled to be more than 1 mm;

[0008] The fourth step is to allow the foam adhesive solvent to solidify and then stick to the surface of doors and windows.

[0009] Furthermore, in the third step, the spraying device includes a frame, a rotating shaft rotatably arranged in the middle of the frame, an installation mechanism fixedly arranged on the top of the rotating shaft and used to install the building door and window profiles, a two-axis movable platform arranged on the top of the frame, and a spray gun arranged at the bottom of the two-axis movable platform. Before spraying the building door and window aluminum profiles, they are first placed on the installation mechanism and fixed, and then the two-axis movable platform drives the spray gun to move back and forth left and right. As the rotating shaft rotates 360 degrees, the building door and window aluminum profiles can be sprayed 360 degrees.

[0010] Furthermore, the mounting mechanism includes a connecting block arranged at the top of the rotating shaft, a positioning block arranged at the top of the connecting block, a first clamping block slidably arranged on one side of the positioning block, a second clamping block slidably arranged on the other side of the positioning block, a left flip block rotatably arranged in the connecting block and located at the bottom of the positioning block, a right flip block rotatably arranged at the bottom of the positioning block away from the left flip block, a first driving rod hingedly arranged on the bottom of the left flip block, a first driving rod hingedly arranged at the bottom of the right flip block, a third driving rod arranged at the first driving rod and the bottom of the first driving rod, a motor for driving the third driving rod to rotate, and a spring arranged between the first clamping block and the second clamping block.

[0011] Furthermore, two groups of fourth driving rods are arranged in parallel on one side of the first clamping block, two groups of fifth driving rods are arranged in parallel on the side of the second clamping block close to the first clamping block, a sixth driving rod is arranged at the connection between the fourth driving rod and the fifth driving rod, a guide wheel is arranged on the top of the sixth driving rod, and an opening is arranged in the middle of the positioning block for the sixth driving rod to pass through.

[0012] Furthermore, the fourth driving rod and the fifth driving rod have the same size.

[0013] By adopting the above technical solution, the beneficial effects of the present invention are:

[0014] The spray-type protective film spraying method for building doors and windows sprays the foam solvent on the surface of the aluminum profile of the building doors and windows at 360 degrees. The spraying speed and efficiency are fast. After the foam solvent is cured and adhered to the surface of the doors and windows, a thin film layer will be formed. The thin film layer has good dustproof and waterproof properties, and effectively protects the surface of the doors and windows in all directions. In addition, during the installation process, the thin film layer protects the surface of the doors and windows, which solves the technical problems that manual packaging takes a long time and is difficult to provide all-round protection, resulting in easy damage to the products during installation and transportation, and low efficiency of packaging and protection in the doors and windows industry.

[0018] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0019] refer to Figures 1 to 3 This embodiment provides a method for spraying a spray-type protective film on building doors and windows, comprising the following steps:

[0020] The first step is to clean the doors and windows that need to be sprayed to remove oil and dust, and then output them to the spraying station;

[0021] The second step is to prepare the foaming glue solvent, and stir 15-45% of the liquid glue, 10-30% of the conditioning agent, 1-5% of the putty powder, and the remaining 20-74% of the foaming glue solvent according to the above proportions through a mixer for 1-5 minutes, and fully mix and stir. After completion, put it into the spray gun of the spraying device; the best use ratio is 50% of the foaming glue solvent, 30% of the liquid glue, 18% of the conditioning agent, and 2% of the putty powder, and 50% of the foaming glue solvent, which can be increased or decreased according to the above ratio;

[0022] The third step is to adjust the spray gun pressure of the spraying device to 0.3-0.5Mpa, and spray the prepared foaming adhesive solvent on the surface of the building doors and windows, with the thickness controlled to be more than 1 mm, preferably controlled to be between 3-5 mm;

[0023] Step 4: After completion, the foam adhesive solvent will solidify and be pasted on the surface of doors and windows.

[0024] After the foaming adhesive solvent solidifies and sticks to the surface of doors and windows, it will form a thin film layer. The thin film layer has good dustproof and waterproof properties, effectively protecting the surface of doors and windows. During the installation process, the thin film layer protects the surface of doors and windows, which can prevent bumps and scratches during the installation process.

[0025] When the doors and windows are installed, use tools to gently peel off the film layer and tear it off with your hands. Since the foam glue solvent will form an integrated film after solidification, there will be no residue on the profile and glass surface after tearing it off. The surface of the doors and windows is clean and hygienic, achieving the effect of a brand new product leaving the factory.

[0026] The thin film layer formed by the foaming glue solvent is used to protect the surface of building doors and windows after production, ensuring that the doors and windows are not damaged during transportation and installation, and is easy to operate and the packaging efficiency is greatly improved, which is convenient for later removal, ensuring that the surface of the doors and windows is clean and hygienic. Compared with the existing protective film packaging, since the surface of the doors and windows is irregular, it is necessary to manually stick the film and then wrap the protective tape, and the manual packaging efficiency is low. The wrapped protective tape is easy to separate from the doors and windows, and the thickness of the stuck film is low, which is easy to cause bumps during transportation and installation. The thin film layer formed by the foaming glue solvent can prevent the above problems.

[0027] The spraying device includes a frame 100, a rotating shaft 200 rotatably arranged in the middle of the frame 100, an installation mechanism 300 fixedly arranged on the top of the rotating shaft 200 and used to install the building door and window profiles, a two-axis movable platform 400 arranged on the top of the frame 100, and a spray gun 500 arranged at the bottom of the two-axis movable platform 400. Before spraying the building door and window aluminum profiles, they are first placed on the installation mechanism 300 for fixation, and then the two-axis movable platform 400 drives the spray gun 500 to move back and forth left and right. As the rotating shaft 200 rotates 360 degrees, the building door and window aluminum profiles can be sprayed 360 degrees.

[0028] The mounting mechanism includes a connecting block 301 arranged at the top of the rotating shaft, a positioning block 302 arranged at the top of the connecting block 301, a first clamping block 303 slidably arranged on one side of the positioning block 302, a second clamping block 304 slidably arranged on the other side of the positioning block 302, a left flipping block 305 rotatably arranged in the connecting block 301 and located at the bottom of the positioning block 302, a right flipping block 306 rotatably arranged at the bottom of the positioning block 302 away from the left flipping block 305, a first driving rod 307 hingedly arranged on the bottom surface of the left flipping block 305, a first driving rod 308 hingedly arranged at the bottom of the right flipping block 306, a third driving rod 309 arranged at the bottom of the first driving rod 307 and the first driving rod 308, and a third driving rod 309 for driving the third driving rod 309 to rotate. The motor 310 and the spring 311 are arranged between the first clamping block 303 and the second clamping block 304, the first driving rod 307 and the first driving rod 308 are hinged at the bottom, two groups of fourth driving rods 312 arranged in parallel are arranged on one side of the first clamping block 303, and two groups of fifth driving rods 313 arranged in parallel are arranged on the side of the second clamping block 304 close to the first clamping block 303, a sixth driving rod 314 is arranged at the connection between the fourth driving rod 312 and the fifth driving rod 313, a guide wheel 315 is arranged on the top of the sixth driving rod 314, and an opening 316 for the sixth driving rod 314 to pass through is arranged in the middle of the positioning block 302; the fourth driving rod and the fifth driving rod have the same size, which is conducive to bulk purchase.

[0029] The existing opening position of the hanging part of some aluminum profiles of doors and windows has a hanging part connected to the glass, aluminum profile and heat insulation material. Direct spraying is easy to cause filling and blocking of the hanging part. Since it is inside the opening of the hanging part of the aluminum profile, it is not easy to clean during later use. Through the setting of the installation mechanism, when in use, the aluminum profile of the door and window is placed above the positioning block, the motor rotates, and the third drive rod drives the first drive rod and the first drive rod to move downward, the left flip block rotates downward ninety degrees, and the right flip block flips downward 90 degrees. The first clamp block and the second clamp block move toward the middle under the action of the spring. At this time, the first clamp block and the second clamp block shrink into the positioning block. At this time, the hanging part of the aluminum profile of the door and window is inserted into the connecting block and the positioning block, and then the motor continues to drive the third drive rod to rotate, and the third drive rod drives the first drive rod and the first drive rod to rotate upward. During the upward rotation of the first drive rod and the first drive rod, the left flip block and the right flip block rotate upward ninety degrees, and the flip block is flipped. During the process, the first clamping block and the second clamping block are driven to move to both sides, and the hanging part of the door and window aluminum profile is fixed on the connecting block and the fixing block. The two-axis moving platform will drive the spray gun to move back and forth left and right to spray the surface of the door and window aluminum profile. The rotating shaft drives the door and window aluminum profile to rotate 360 ​​degrees to achieve uniform spraying. Since the connecting block can block the opening position of the door and window aluminum profile hanging part, the foaming glue solvent can be prevented from being sprayed on the opening position of the door and window aluminum profile hanging part. At the same time, the installation mechanism can fix the door and window aluminum profile. The existing assembly line conveys spraying on the three outer surfaces, which is easy to miss one surface. The aluminum profile of the door and window is clamped in the center, and the length of the door and window aluminum profile is not fixed. Before each spraying, a sealant must be inserted into the position of the door and window aluminum profile hanging part. After the spraying is completed, the sealant is manually cleaned. The spraying efficiency is low. The installation mechanism blocks the opening position of the door and window aluminum profile hanging part while fixing and installing the door and window aluminum profile. After the spraying solidifies, the door and window aluminum profile can be directly disassembled.

[0030] When the spraying is completed and solidified, the first clamp block and the second clamp block move toward the middle, and the first clamp block and the second clamp block drive the fourth drive rod and the fifth drive rod to be squeezed toward the middle, and the sixth drive rod connected with the fourth drive rod and the fifth drive rod moves upward, and the guide wheel at the top of the sixth drive rod lifts the door and window aluminum profile, and the door and window aluminum profile moves upward, and the foaming glue solvent between the opening position of the door and window aluminum profile hanging part and the connection position of the connecting block separates and falls off, which makes it more convenient for manual or mechanical arms to pull out the door and window aluminum profile upward.
