[0002] The liquid film coating technology is a technology for covering a liquid film on the surface of an object, which can be applied to multiple fields. The principle of the liquid film coating technology is to immerse the object to be film-coated in a liquid, and then take it out and dry it, or cure the liquid by heating or other means, so as to form a film on the surface of the object. This film can provide functions such as protection, decoration, and insulation, and is commonly used in the field of advertising spraying. When using liquid film coating equipment for liquid film coating, a feeding device is usually required to convey the material to be film-coated into the equipment.

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Refer to Figures 1-5 , a feeding device for fluid film coating, including a fixed frame 1, an adjusting component 2 and a fixing component 7. A first driving roller 3, a second driving roller 4 and a traction roller 5 are respectively arranged on the fixed frame 1. A material roll 6 is arranged between the two adjusting components 2. One side of the material roll 6 is respectively wound around the surfaces of the first driving roller 3, the second driving roller 4 and the traction roller 5.

[0025] There are two adjusting components 2, and the two adjusting components 2 are rotatably installed on the fixed frame 1. The adjusting component 2 includes a fixed rod 201, on which a spring 202 is installed by interference fit. A limiting ring is installed on the fixed rod 201 with a clearance fit, and the limiting ring is located at the other end of the spring 202. An active sleeve 203 is slidably fitted on the surface of the fixed rod 201. Two pairs of sliding grooves 2011 are formed on the surface of the fixed rod 201, and two pairs of sliding blocks 2031 are arranged on the active sleeve 203. The two pairs of sliding blocks 2031 cooperate with the two pairs of sliding grooves 2011, and the active sleeve 203 is located at one end of the spring 202. When liquid coating is applied to the material, the feeding device provided on the liquid coating equipment needs to convey the material roll 6 to the feeding port of the liquid coating equipment. During the feeding process, first take out the material roll 6, align the cavity at one end of the material roll 6 with one end of the adjusting component 2 on one side inside the fixed frame 1, and then squeeze so that the material roll 6 is sleeved on the surface of the active sleeve 203 and contacts one side of the active sleeve 203. Then, the material roll 6 is used to squeeze the active sleeve 203, so that the active sleeve 203 slides on the surface of the fixed rod 201 through the cooperation of the two pairs of sliding blocks 2031 and the two pairs of sliding grooves 2011. By the sliding of the active sleeve 203 on the fixed rod 201, one end of the spring 202 is squeezed by the active sleeve 203, so that the spring 202 is compressed under force. After the material roll 6 is sleeved on the fixed rod 201 and is kept horizontal with the fixed rod 201, gradually reduce the squeezing force of the material roll 6 on the spring 202, so that the spring 202 rebounds and pushes the active sleeve 203 outward, so that the material roll 6 moves horizontally away from one side of the adjusting component 2. Then align the other end of the material roll 6 with the adjusting component 2 on the other side inside the fixed frame 1, and the cavity of the material roll 6 is sleeved on the adjusting component 2. Through the resilience generated by the active sleeve 203 on the adjusting component 2 on one side inside the fixed frame 1, the material roll 6 is pushed, and then the active sleeve 203 on the adjusting component 2 on the other side is squeezed, so that the active sleeve 203 slides on the fixed rod 201 and squeezes the spring 202. Through the squeezing force and resilience of the two springs 202, the two active sleeves 203 slide relatively on the corresponding fixed rods 201, so that the material roll 6 forms a balance between the two adjusting components 2. After the placement of the material roll 6 is completed, pull out one end of the material roll 6 and wind it around the first driving roller 3, the second driving roller 4 and the traction roller 5 respectively, and then send one end of the material roll 6 into the feeding port of the liquid coating equipment through the traction roller 5, so that material rolls 6 of different sizes can be placed, the applicable range is increased, and the material roll 6 can be kept centered, avoiding the deviation of the material roll 6, ensuring that the material roll 6 can be conveyed to the liquid coating equipment in a flat and centered manner, and ensuring the liquid coating effect of the material roll 6.

[0026] At one end of each of the two adjusting components 2, there are provided two pairs of fixing components 7. The fixing component 7 includes an arc-shaped pressing plate 701 and a spring rod 703. On the surface of one end of the fixing rod 201, there are provided two pairs of placing grooves 2012. In each of the two pairs of placing grooves 2012, there is provided a spring rod 703. The top end of the spring rod 703 passes through the placing groove 2012 to the outside of the fixing rod 201. A through hole 2013 is provided in the placing groove 2012. The top end of the spring rod 703 cooperates with the through hole 2013. On one side of the arc-shaped pressing plate 701, there is provided a connecting plate 702. The bottom of the arc-shaped pressing plate 701 is connected to the top end of the spring rod 703. On the surface of the top of the arc-shaped pressing plate 701, there are provided three anti-slip pieces 704. The three anti-slip pieces 704 are all elastic rubber sheets. Anti-slip strips are provided on the surfaces of the three anti-slip pieces 704. During the process of sleeving the cavity of the material roll 6 onto the movable sleeve 203 of the adjusting component 2, the cavity of the material roll 6 squeezes the two pairs of fixing components 7 provided at one end of the adjusting component 2. First, the inner wall of the cavity of the material roll 6 contacts and squeezes the two pairs of connecting plates 702. Through the squeezing of the two pairs of connecting plates 702 by the material roll 6, the two pairs of arc-shaped pressing plates 701 receive pressure through the two pairs of connecting plates 702. The pressure received by the arc-shaped pressing plate 701 is transmitted to the spring rod 703 at the bottom of the arc-shaped pressing plate 701, causing the spring rod 703 to be compressed in the placing groove 2012. Then, continue to push the material roll 6, so that the inner wall of the cavity of the material roll 6 moves towards the surfaces of the two pairs of arc-shaped pressing plates 701 through the two pairs of connecting plates 702. When the surfaces of the two pairs of arc-shaped pressing plates 701 are completely in contact with the inner wall of the cavity of the material roll 6, the squeezing forces received by the two pairs of arc-shaped pressing plates 701 cause the corresponding spring rods 703 at their respective bottoms to contract, so that the two pairs of arc-shaped pressing plates 701 can be flush with the movable sleeve 203. By compressing the two pairs of spring rods 703 into the corresponding placing grooves 2012, the arc-shaped pressing plate 701 receives the resilience of the spring rod 703. Through the resilience received by the arc-shaped pressing plate 701, the two pairs of arc-shaped pressing plates 701 are pressed tightly against the inner wall of the material roll 6, and the anti-slip pieces 704 provided on the surface of the arc-shaped pressing plate 701 are used to prevent the material roll 6 from rolling during feeding. When the material roll 6 is conveyed into the liquid film laminating device, the material can only be conveyed and pulled by the rotation of the two adjusting components 2, so that the material roll 6 can be fixed during the conveying process, preventing the material roll 6 from rolling during the conveying process, ensuring that the material will not produce wrinkles or inclinations during conveying, and improving the film laminating effect of the material.
