Description

Technical Field

[0001] The invention relates to the technical field of coating equipment, and in particular to coating equipment for producing high temperature resistant protective tapes. Background Art

[0002] High temperature protective tape is an adhesive tape that can be used in high temperature environments. It is mainly used in the electronics industry. Its temperature resistance is usually between 120°C and 260°C. It is often used in spray painting, paint leather processing, coating masking, and fixing in the process of electronic parts, printed circuit boards, and high temperature processing masking. Common high temperature protective tapes include KAPTON high temperature tape, Teflon high temperature tape, high temperature masking tape, PET green high temperature tape, and high temperature double-sided tape. Tape coating is to evenly apply glue on the tape through a coating machine, and then obtain a molded tape after drying, winding, and cutting. In order to improve the uniformity of glue application, there is a diluent component in the glue to improve the fluidity of the glue. However, the diluent has the characteristic of being volatile. As the diluent in the glue evaporates, the viscosity of the glue increases, resulting in uneven tape coating and reduced tape quality. The specifications of the tape are mainly distinguished by the width and length factors.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] The present invention provides a technical solution: a coating device for producing high temperature resistant protective tape, such as Figure 1-Figure 7 As shown, it includes a base 1, and a coating mechanism 2, a bracket 3 and a winding mechanism 4 are fixedly connected to the upper surface of the base 1 from left to right in sequence.

[0029] Furthermore, the stirring assembly 24 includes a dust cover 241 fixedly connected to the front side of the coating box 21, a first motor 242 is installed at the bottom of the front side of the dust cover 241, a first sprocket 243 is installed at the output end of the first motor 242, and a stirring rod 244 is also installed at the output end of the first motor 242. The stirring rod 244 rotates under the drive of the first motor 242 to stir the glue, and a rotating shaft 245 capable of rotating around its own axis is installed at the top of the inner cavity of the dust cover 241 through a bearing, and a second sprocket 246 is installed on the outer wall of the rotating shaft 245. The second sprocket 246 is connected to the first sprocket 243 through a chain, and the diameter of the second sprocket 246 is larger than that of the first sprocket 243, thereby reducing the angular velocity of the second sprocket 246.

[0030] Furthermore, the dilution component 25 includes a valve body 251 fixedly connected to the left end of the top of the coating box 21, and a dilution liquid tank 252 is fixedly connected to the top of the valve body 251. The dilution liquid tank 252 is used to store glue dilution liquid. A rotatable valve core 253 is installed in the inner cavity of the valve body 251. The front end of the valve core 253 is connected to the rear end of the rotating shaft 245 through a coupling. A plurality of guide holes 254 are equidistantly provided on the outer wall of the valve core 253 from front to back. The guide holes 254 can be rotated by rotating the valve core 253. When the guide holes 254 are rotated to a vertical direction, the dilution liquid stored in the dilution liquid tank 252 can drip down, and the dilution liquid can be added to the glue.

[0031] Furthermore, the winding mechanism 4 includes a vertical plate 41 fixedly connected to the right rear of the upper surface of the base 1, a second motor 42 is installed at the top rear side of the vertical plate 41, a reel 43 is installed at the output end of the second motor 42, and the outer wall of the reel 43 is used to install a reel. When the second motor 42 drives the reel 43 to rotate, the reel can rewind the tape, and a fixed-length component 44 is installed at the bottom front side of the vertical plate 41.

[0032] Furthermore, the fixed-length component 44 includes a box body 441 fixedly connected to the bottom end of the front face of the vertical plate 41, an alarm light 442 is installed on the right side wall of the box body 441, a screw 443 is screwed on the front face of the box body 441, and a push plate 444 and a spring 445 are respectively inserted into the inner cavity of the box body 441 from front to back. When the screw 443 rotates clockwise, the screw 443 can push the push plate backward, and the push plate 444 is pushed forward under the elastic force of the spring 445. Guide grooves 446 are provided on the left and right sides of the push plate 444, and a lifting column 447 that can slide up and down is inserted on the top of the box body 441. The lifting column 447 has two upper and lower parts. Rollers 449 and pins 448 are respectively installed at the ends, and the pins 448 are inserted in the inner cavity of the guide groove 446. The guide groove 446 is obliquely distributed on the outer wall of the push plate 444. When the push plate 444 moves forward and backward, the inclined surface of the guide groove 446 can squeeze the pin 448 upward or downward to realize the up and down movement of the lifting column 447. Contacts 410 are installed on the rear side of the inner cavity of the box body 441 and the rear end of the push plate 444, and the contacts 410 are electrically connected to the alarm light 442. The two contacts 410 are located on the same horizontal line. When the push plate 444 moves backward, the two contacts 410 can contact each other, so that the alarm light 442 is powered on and illuminated.

[0033] Working principle: Step 1: Place the adhesive tape coil on the support plate 5, let the adhesive tape pass between the two guide rollers 23, and then pass through the drying box 6. A tape reel is installed on the reel 43. The reel is driven by the second motor 42 to rotate, and the adhesive tape moves from left to right. The reel winds up the adhesive tape. The guide roller 23 is dipped with glue. The scraper 26 removes excess glue on the surface of the guide roller 23. As the guide roller 23 rotates, the glue adheres to the surface of the tape. The glue is dried in the drying box 6 to achieve tape coating. Step 2: As the storage time of the glue passes, the diluent in the glue gradually evaporates, and the first motor 242 drives the first sprocket 243 and the stirring rod 244 to rotate. The stirring rod 244 can rotate the glue, and the first sprocket 243 and the second sprocket 246 drive the valve core 253 to rotate. When the guide hole 254 rotates to the vertical direction, the guide hole 254 plays a drainage role, allowing the diluent in the diluent box 252 to drip into the coating box 21, and then stirred by the stirring rod 244, so that the diluent is fully integrated into the glue, so that the diluent in the glue is replenished; Step 3: Adjust the fixed length assembly 44 according to the tape winding length. When the screw 443 rotates clockwise or counterclockwise, the screw 443 can move backward or forward, and the screw 443 can push the push plate 444 to move backward or forward. Under the action of the inclined surface of the guide groove 446, the pin 448 is squeezed downward or upward, and the lifting column 447 moves downward or upward, changing the distance between the roller 449 and the reel 43; As the thickness of the tape on the reel gradually increases, the tape gradually squeezes the roller 449 downward, causing the lifting column 447 to move downward, the pin 448 to squeeze the guide groove 446, and the push plate 444 to move backward. When the two contacts 410 contact each other, the alarm light 442 is powered on and illuminates, indicating that the tape has been rolled up to the specified length.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
