Description

Technical Field

[0001] The utility model relates to the technical field of water transfer printing films, in particular to large-scale water transfer printing film paving equipment. Background Art

[0002] The water transfer film uses low-temperature water-soluble PVA (polyvinyl alcohol) film as the substrate. The pattern is printed on the PVA substrate, and then the water transfer film with the printed pattern is unfolded and placed on the water surface. The side without the printed pattern is in contact with the water, and the side with the printed pattern faces up. After the PVA of the base layer is completely flat on the water surface, the activator is sprayed on the pattern, and the pattern ink is dissolved. As the PVA of the base layer is gradually dissolved by water, the dissolved pattern ink will float on the water surface. At this time, the product to be transferred is pressed from top to bottom into the water transfer film, so that the product is completely covered by the water transfer film and immersed in water. The pattern is transferred to the product using the principle of water pressure. When manually laying the water transfer film on the water surface, bubbles appear between the film and the water surface, causing faults or deviations in the pattern printed on the product surface. Usually, if the product to be transferred is small, the corresponding water transfer film area is small, and the bubbles generated are small. The pattern ink floating on the water surface is manually moved to discharge the bubbles. However, when manually laying a large area of ​​water transfer film, a large number of bubbles are more likely to appear, and it is difficult to manually discharge large areas of bubbles after the PVA of the base layer is dissolved, resulting in the scrapping of a large area of ​​water transfer film, causing waste.

[0022] Example

[0023] Please refer to Figure 1 The utility model provides a large-scale water transfer film paving device, including a placing tank 10, a water tank 20 and a paving mechanism 30 arranged on the water tank 20; the placing tank 10 is used to place a rolled water transfer film, the water tank 20 is filled with water, and the paving mechanism 30 is used to spread the water transfer film on the water surface of the water tank 20.

[0024] Please refer to Figure 1-4A support plate 201 is installed at one end of the water tank 20 along the length direction, and a cutting device is installed on the support plate 201; specifically, the cutting device includes a guide rail 202 and a cutter 203. The guide rail 202 spans the water tank 20, and the cutter 203 moves back and forth along the guide rail 202. When the water transfer film is laid flat on the water surface of the water tank 20 and then spreads over the guide rail 202, the cutter 203 slides along the guide rail 202 to cut the water transfer film. Furthermore, a guide roller 204 is installed on the end of the support plate 201 away from the cutting device. When the rolled water transfer film is transferred from the placement tank 10 to the paving mechanism 30, the guide roller 204 can play a role in assisting the transmission, so as to prevent the edge of the support plate 201 from directly contacting the water transfer film and causing unsmooth transmission.

[0025] Please refer to Figure 1-4 The paving mechanism 30 includes a support frame 301, and the support frame 301 includes four support columns and a frame above. A movable frame 302 is movably installed on the support frame 301, and the movable frame 302 can move back and forth along the frame. Specifically, a driving motor 3021 and a driving shaft are installed on the movable frame 302, and the driving motor 3021 is connected to the driving shaft. Rollers 3022 are installed at both ends of the driving shaft, and the rollers 3022 are placed on the upper end surfaces of both sides of the support frame. The driving motor 3021 is controlled to drive the rollers 3022 at both ends to roll along the frame to realize the back and forth movement of the movable frame above the water tank 20, thereby driving the flattening roller 307 to move back and forth along the water surface of the water tank 20.

[0026] Please refer to Figure 1-4 A retractable flattening roller 307 and several auxiliary rollers 308 are installed on the movable frame 302. The movable frame 302 drives the flattening roller 307 and the auxiliary rollers 308 to move on the water tank 20. Specifically, the auxiliary rollers 308 are used to assist in the transmission of the water transfer film. Two telescopic cylinders 304, two cranks 303, two connecting rods 305 and a guide block 306 are installed on the movable frame 302. One end of the crank 303 is rotatably installed on the movable frame 302 through a bearing. The piston rod of the telescopic cylinder 304 is connected to the middle part of the crank 303. The telescopic cylinder 304 is controlled to drive the crank 303 to swing around the position connected to the movable frame 302. The other end of the crank 303 is connected to the connecting rod 305. Specifically, a strip hole is opened at one end of the crank 303 connected to the connecting rod 305. One end of the connecting rod 305 is fixed with the flattening roller 307 and the other end is installed with the guide The guide wheel is placed in the strip hole, and the guide wheel installed on the connecting rod 305 can move and rotate in the strip hole. The connecting rod 305 can slide through the guide block 306. One end of the connecting rod 305 is connected to the flattening roller 307, and the other end is movably connected to the crank 303. When the crank 303 swings, it drives the connecting rod 305 to move along the guide block 306. The connecting rod 305 drives the flattening roller 307 to extend obliquely downward or lift obliquely upward into the water tank 20, flattening the water transfer film on the water surface and slowly moving it to flatten it, so as to achieve the effect of flattening a large area of ​​water transfer film on the water surface.

[0027] The operation process of the utility model is as follows: first, the movable frame 302 is moved to one end of the water tank 20 away from the support plate 201, and the telescopic cylinder 304 drives the flattening roller 307 to be lifted obliquely upward. Then, the free end of the water transfer film is manually pulled to pass over the auxiliary roller 308 and then pass under the flattening roller 307 to one end edge of the water tank 20. Then, the telescopic cylinder 304 is controlled to slowly extend downward to press the water transfer film on the water surface of the water tank 20. Then, the movable frame 302 is controlled to slowly move toward the side close to the support plate 201, driving the flattening roller 307 to slowly flatten the water transfer film on the water surface. When the flattening roller 307 approaches the guide rail 202, the flattening roller 307 is lifted to allow the water transfer film to be spread over the guide rail 202. Finally, the cutter 203 moves along the guide rail 202 to cut the water transfer film.
