It is made of glass fiber as the base cloth, coated with Teflon emulsion and dried to make Teflon glass fiber cloth.

The glue used for the second coating is silicone adhesive, which is rolled onto the surface of the Teflon coil, and then the excess silicone adhesive is removed by a scraper. After curing, Teflon tape can be obtained. Before coating, Teflon coil is affected by environmental humidity and friction.

The rubber roller 54 is driven to rotate by the second motor 53, so that the silicone adhesive on the rubber roller 54 is coated on the surface of the Teflon coil.

[0028] Furthermore, Figure 3 and Figure 4 As shown, the diluting mechanism 7 includes a diluent tank 71 installed on the left side of the upper surface of the glue box 1 along the front-to-back direction. The diluent tank 71 is used to store the diluent for the silicone adhesive. A third motor 72 electrically connected to the controller 2 is installed at the bottom of the front of the diluent tank 71.

The roller 73 can be rotated under the drive of the third motor 72. The guide grooves 74 carry the diluent to move. The different positions of the guide grooves 74 are used to make the diluent drip evenly into the glue box 1. The maximum spacing between the guide grooves 74 is less than the inner cavity length of the glue box 1 to prevent the diluent from falling outside the glue box 1 and causing waste.

[0029] Furthermore, Figure 5As shown, the unloading mechanism 8 includes two second support plates 81 respectively installed on the right ends of the front and rear sides of the rubber box 1, and the left and right ends of the inner side of the second support plate 81 are respectively installed with a rotatable first guide roller 82 and a second guide roller 83, and the first guide roller 82 and the second guide roller 83 can convey the Teflon coil by rolling. An inclined scraper 84 is installed in the middle of the inner side of the second support plate 81, and the scraper 84 is used to scrape off the excess silicone adhesive on the surface of the Teflon coil to make the thickness of the silicone adhesive on the Teflon coil uniform. A protrusion 85 is installed at the front end of the first guide roller 82, and both sides of the protrusion 85 are inclined surfaces. A drying component 86 is installed on the left side of the upper surface of the second support plate 81 along the front-to-back direction, and a timing start component 87 is installed on the left end of the front side of the second support plate 81 located at the front side.

[0030] Furthermore, Figure 6 As shown, the drying component 86 includes a drying box 861 installed on the left side of the upper surface of the second support plate 81, and brackets 862 at the front and rear ends of the left side of the upper surface of the drying box 861. The Teflon coil is set up through the brackets 862. A wind knife 863 is installed on the front side of the drying box 861 in the vertical direction, and an air supply unit 864 is installed on the right side wall of the drying box 861 in the front and rear direction. The front end of the air supply unit 864 is connected to the outer wall of the wind knife 863 through an air pipe. A rotatable third guide roller 865 is installed at the bottom of the inner cavity of the drying box 861, and the Teflon coil is conducted by the rolling of the third guide roller 865.

[0031] Furthermore, Figure 7 As shown, the air supply unit 864 includes a heating cylinder 8641 installed on the right side wall of the drying box 861 along the front-to-back direction, an air hood 8642 is installed at the front end of the heating cylinder 8641, and the front end of the air hood 8642 is connected to the outer wall of the wind knife 863 through an air pipe. The inner cavity of the heating cylinder 8641 is respectively installed with a heater 8643, a negative ion generator 8644, a fan 8645 and a filter plate 8646 from front to back, and the negative ion generator 8644 and the fan 8645 are both electrically connected to the controller 2. Under the suction of the fan 8645, the external air is sucked into the heating cylinder 8641, the filter plate 8646 filters the dust in the gas, the negative ion generator 8644 generates negative oxygen ions, and the negative oxygen ions are allowed to flow with the gas, and the heater 8643 heats the gas, so that the wind knife 863 blows hot air to the Teflon coil, and the negative oxygen ions neutralize the charge on the Teflon coil to eliminate static electricity. At the same time, the heat can also dry the Teflon coil.

[0032] Furthermore, Figure 8As shown, the timing start component 87 includes a dust cover 871 installed on the left end of the front face of the second support plate 81 located on the front side, a counter 872 is installed on the front face of the dust cover 871, a first contact 873 is installed on the right end of the top of the inner cavity of the dust cover 871, the first contact 873 is externally connected to a power supply, a swing rod 874 capable of swinging left and right is installed on the top of the inner cavity of the dust cover 871 through a pin shaft, one end of a tension spring 875 is clamped on the left side wall of the swing rod 874, and the other end of the tension spring 875 is clamped on the top of the inner cavity of the dust cover 871, and the swing rod 874 is pulled to move left under the tension of the tension spring 875, and the bottom of the swing rod 874 is pulled to move left. A rotatable roller 876 is installed at the end, and the roller 876 is in contact with the first guide roller 82. A second contact 877 electrically connected to the counter 872 is installed on the right side of the rocker arm 874. The second contact 877 and the first contact 873 are located on the same horizontal line. When the first guide roller 82 rotates, the inclined surface of the protrusion 85 can squeeze the rocker arm 874 to the right, so that the second contact 877 on the rocker arm 874 contacts the first contact 873, and the counter 872 counts once. When the counter 872 reaches the set value, an electrical signal is transmitted to the controller 2, so that the controller 2 can control the third motor 72 to start.

[0033] Working principle: Step 1: The Teflon coil is placed on the bracket 862. The Teflon coil is installed on the winder through the third guide roller 865, the first guide roller 82 and the second guide roller 83. As the Teflon coil moves, the fan 8645 sucks in the external gas, and the filter plate 8646 filters the dust in the gas. Then the negative ion generator 8644 generates negative oxygen ions to move with the gas, and the heater 8643 heats the gas. Finally, the wind knife 863 blows hot air to the Teflon coil. The negative oxygen ions neutralize the charge on the Teflon coil, eliminate static electricity, and improve the adsorption of the silicone adhesive. The heat can dry the Teflon coil to prevent the adhesive on the surface of the Teflon coil from generating bubbles due to high humidity. Step 2: The controller 2 starts the pump 6. The suction of the pump 6 guides the silicone adhesive in the glue box 1 into the glue groove 52. The bottom opening of the glue groove 52 drips the adhesive onto the rubber roller 54. Since the second motor 53 drives the rubber roller 54 to rotate, the rubber roller 54 transfers the adhesive to the surface of the Teflon coil. The scraper 84 scrapes off the excess adhesive to make the adhesive thickness on the surface of the Teflon coil uniform, thereby achieving the Teflon coil glue coating. Step three, as the first guide roller 82 rotates, the inclined surface of the protrusion 85 repeatedly squeezes the roller 876, allowing the swing rod 874 to swing to the right. When the second contact 877 contacts the first contact 873, the counter 872 counts until the count times reaches the set value of the counter 872. The counter 872 sends an electrical signal to the controller 2. The controller 2 starts the third motor 72. The third motor 72 drives the roller 73 to rotate a certain angle. The guide groove 74 carries the diluent to move, allowing the diluent to drip evenly into the glue box 1. At the same time, the first motor 3 drives the stirring rod 4 to rotate to mix the adhesive and the diluent, so that the fluidity of the adhesive is constant and the coating quality is guaranteed.

[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.
