Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Features in the embodiments described below may be combined with each other without conflict.
The first embodiment is as follows:
please refer to fig. 1-3, the utility model provides a comma coater suitable for elimination bubble for scribble the glue solution of setting thickness on membrane material 8, including frame 1, scraper 3, backing bar 2 and glue spreader 4, scraper 3 with be equipped with the rubber coating space between backing bar 2, this rubber coating space has confirmed the above-mentioned glue solution thickness of coating on membrane material 8, the rubber coating space sets up to supply membrane material 8 and the glue solution of setting for thickness to pass through, and behind membrane material 8 passed through the rubber coating space, the glue solution was attached to on membrane material 8. The glue coating groove 4 is arranged on the glue facing side of the back roll 2. The blade 3 in the present embodiment is a comma blade, and may be a blade having another shape. The comma coater further comprises a bubble eliminating device for eliminating bubbles in the glue solution, wherein the bubble eliminating device at least comprises one of the following components: (i) an ultrasonic device 10, and (ii) a heating device 9. That is, the bubble removing means may be the ultrasonic device 10 alone, the heating device 9 alone, or a combination of both. The ultrasonic device utilizes ultrasonic technology to crush the bubbles wrapped in the glue solution so as to eliminate the bubbles. Ultrasonic waves are mechanical waves of extremely short wavelength, typically shorter than 2cm (centimeters) in air. It must rely on a medium for propagation and cannot exist in a vacuum (e.g., space). The water-based ultrasonic wave generator has a longer propagation distance in water than in air, but is easy to lose in air due to the short wavelength, is easy to scatter, is not as far as audible sound and infrasonic wave, but is easy to obtain anisotropic sound energy due to the short wavelength, and can be used for cleaning, crushing stones, sterilizing and disinfecting and the like. Has a plurality of applications in medicine and industry. The utility model provides an ultrasonic wave part can directly purchase ripe accessory in market, need pay attention to select assorted power during the lectotype. The heating device 9 is used for improving the casting property of the glue solution by increasing the temperature of the glue solution, and further eliminating bubbles in the flowing process.
Specifically, as shown in fig. 1 and 2, the bubble removing device includes a heating device 9 and an ultrasonic device 10, and the heating device 9 is fixedly attached to the lower glue baffle 401 to increase the temperature of the glue solution in the glue coating tank 4. The heating device 9 has an electric heating wire therein and is attached to the bottom surface of the lower glue-blocking plate 401. Because the glue coating groove 4 is rectangular shape, in order to make everywhere glue solution temperature in the glue coating groove 4 even, further set up a plurality of heating device 9, its equipartition is on the bottom surface that keeps off offset plate 401 down, specifically can be two, three or more, also can be the heating plate that designs into can be attached on glue coating groove 4 bottom surface to the realization is to glue solution in the glue coating groove 4 and carry out the even heating. The ultrasonic device 10 is also arranged on the lower glue baffle 401, and because the lower glue baffle 401 is large in thickness, the ultrasonic device 10 is arranged in the blind hole and attached to the bottom wall of the blind hole, and the bottom wall is thin-walled, so that the ultrasonic can be transmitted to the glue solution in the glue coating tank 4, and the ultrasonic generated by the ultrasonic device 10 can be transmitted to the glue solution without attenuation. Also in order to eliminate the bubbles in the glue solution at various places in the glue tank 4 more uniformly, the present embodiment provides a plurality of ultrasonic devices 10 at different positions of the lower glue barrier 4.
A flow-casting process 801 which takes the glue coating tank 4 as a start and extends to the scraper 3 along the peripheral surface of the back roller under the action of gravity is formed as a process for casting a coating liquid, the flow-casting process 801 is formed on the glue facing side of the back roller, the glue facing side refers to the side of the back roller 2 facing the glue coating tank 4, and the film 8 is attached to the back roller 2 on the glue facing side and is coated with a glue solution; to further reduce air bubbles, the present embodiment also arranges the coating bath 4 on the frame 1 in a distance-adjustable manner with respect to the blade 3 to adjust the casting stroke 801 in accordance with the viscosity of the coating liquid.
As shown in fig. 3, the glue coating groove 4 is obliquely arranged relative to the horizontal plane, and the right side end of the glue coating groove is attached to the back roller 2, so as to prevent the glue solution in the glue coating groove 4 from leaking between the glue coating groove and the back roller, because the glue solution has certain viscosity, the end of the glue coating groove 4 is prevented from damaging the coated film material 8, a micro gap is arranged between the glue coating groove 4 and the back roller 2, in the rotating process of the back roller 2, because the glue facing side of the back roller 2 upwards rotates, an upward acting force can be generated on the glue solution at the gap, and the acting force can prevent the glue solution from leaking from the gap.
The casting stroke refers to the casting length from the coating of the glue solution on the film material 8 to the scraping of the film material 8 by the scraper 3, and specifically is the distance extending along the peripheral surface of the backing roll 2 from the combination position of the glue coating tank 4 and the backing roll 2 to the combination position of the scraper 3 and the backing roll 2, and the distance is the distance extending in the peripheral direction of the backing roll 2. After the glue solution in the glue coating groove 4 is attached to the membrane material 8, the glue solution moves upwards along with the membrane material 8 under the rotation of the back roll 2, and in the moving process, the glue solution attached to the membrane material 8 can flow along the membrane material 8 under the action of gravity. The glue solutions with different viscosities have different casting performances, the lower the viscosity is, the better the casting performance is, the thinner the thickness of the glue solution reaching the scraper 3 is, the more uniform the glue solution is, and no bubbles are generated after the glue solution passes through the scraper 3. For the glue solution with higher viscosity, the casting performance is poorer, and if the bubbles in the glue solution are not eliminated in time, the film material is easy to generate streak marks after passing through the scraper 3, so that defective products are generated. The distance between the glue coating tank 4 and the scraper 3 is changed to prolong the casting stroke 801 of the glue solution, so that the casting of the glue solution with high viscosity can be reduced more fully, and the defects of bubbles, colloidal particle points and the like generated on the membrane material 8 are effectively avoided.

In the present embodiment, the first direction is a vertical direction, and the glue groove 4 is moved in the first direction to be close to or far from the vertical direction to reduce or increase the casting stroke 801 formed between the glue groove 4 and the blade 3. Because the glue facing side of the back roller 2 is a curved surface, the gap between the glue coating groove 4 and the back roller 2 can be changed after the glue coating groove 4 moves up and down, and the glue coating groove 4 can be close to or far away from the back roller 2 when moving in the second direction. The glue groove 4 is far away from the back roller 2, so that a space can be provided for the glue groove to move in the first direction, and the glue groove 4 is close to the back roller 2, so that the glue groove can be attached to the back roller 2 after the casting stroke 801 is adjusted.
