Description

Technical Field

[0001] The present application relates to the technical field of transfer paper leveling, and in particular to a transfer printing paper leveling device. Background Art

[0002] Transfer printing was invented in the 1950s. It is to first use a printing method to print the desired pattern on specially treated paper with suitable dye ink to make transfer printing paper, which is referred to as transfer paper. After that, the ink side of the transfer paper is closely attached to the printed fabric, and the dye is sublimated by heat and pressure, i.e., sublimation, to peel off the ink layer from the paper, and transfer the pattern on the transfer paper to the fabric. The transfer paper needs to be flattened before transfer.

[0003] The utility model patent with announcement number CN220467044U proposes a transfer printing paper leveling device, which drives two pulleys connected by a belt to rotate through a motor. Because the belt is in an 8-shape, the two pulleys can drive two fixed columns to rotate outward synchronously. When the two fixed columns rotate outward, the two pressure wheels squeeze and stretch the two ends of the printing paper outward, so that the printing paper on the support table can be in a taut state, avoiding the situation where the printing paper is wrinkled due to looseness and uneven ironing, and the efficiency of leveling the printing paper is improved.

[0004] The above-mentioned leveling device is only suitable for leveling a shorter transfer paper. When the length of the transfer paper is greater than the length of the heating plate, the transfer paper needs to be fixed for leveling for multiple times, which greatly reduces the work efficiency. Utility Model Content

[0005] The purpose of the utility model is to solve or at least alleviate the problem that the existing leveling device is only suitable for leveling transfer paper with a shorter length. When the length of the transfer paper is greater than the length of the heating plate, the transfer paper needs to be fixed multiple times for leveling, which greatly reduces the work efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A transfer printing paper flattening device comprises a flattening table with a unwinding assembly and a rewinding assembly respectively installed at two ends, an ironing assembly is installed above the flattening table, a steam generating device for introducing hot steam into the ironing assembly is installed at the bottom of the flattening table, the ironing assembly comprises a lower ironing cylinder which is embedded in the middle section of the flattening table and the top is flush with the upper surface of the flattening table, brackets are installed on the flattening table at both ends of the lower ironing cylinder, an upper ironing cylinder which can slide up and down is arranged in the inner cavity of the bracket, and a flat plate whose bottom is flush with the bottom of the upper ironing cylinder is fixedly connected to the side of the upper ironing cylinder close to the unwinding assembly.

[0008] The transfer paper is then rolled up and the roller is moved to the roller bearing assembly by the roller bearing assembly, and the roller bearing assembly is re-mounted on the two first connecting frames. The outer end of the transfer paper is then pulled through between the upper ironing cylinder and the lower ironing cylinder. The upper ironing cylinder is then released so that the upper ironing cylinder slides down to fit the upper surface of the transfer paper under the pushing action of the elastic extrusion member. The high-temperature steam generated inside the steam box is introduced into the upper ironing cylinder and the lower ironing cylinder through the steam pipe. The end of the transfer paper is then slowly pulled to move in the direction of the take-up shaft until the end of the transfer paper is fixed on the take-up shaft for rewinding. During the rewinding process of the take-up shaft, the transfer paper can be driven to move between the upper ironing cylinder and the lower ironing cylinder. The transfer paper is ironed flat at one time by the upper ironing cylinder and the lower ironing cylinder, and the problem that the existing flattening device is only suitable for flattening transfer paper of shorter length is avoided as much as possible. When the length of the transfer paper is greater than the length of the heating plate, the transfer paper needs to be fixed for flattening for multiple times, which greatly reduces the working efficiency.

When the user releases the upper ironing cylinder, the spring can push the upper ironing cylinder to slide down and fit closely with the upper surface of the transfer paper under the action of its own elastic force, making it convenient for the transfer paper to be ironed subsequently by the upper ironing cylinder.

[0017] Optionally, the unwinding assembly includes first connecting frames fixedly connected to both sides of one end of the flattening table, and a rotating shaft parallel to the width direction of the flattening table is passed through one end of the two first connecting frames away from the flattening table.

[0018] By adopting the above technical solution, when using, the user pulls out the rotating shaft, then puts the transfer paper rolled into a roll on the rotating shaft, and reinstalls the rotating shaft on the two first connecting frames. When one end of the transfer paper is pulled, the roll-shaped transfer paper can be driven to rotate on the rotating shaft to unwind the transfer paper. When one roll of transfer paper is flattened, the above steps can be repeated to unwind another roll of transfer paper.

[0019] Optionally, the winding assembly includes two second connecting frames fixedly connected to the other end of the leveling table, a winding shaft is rotatably connected between the two second connecting frames, a winding motor is fixedly connected to the outer wall of one of the second connecting frames, and the output end of the winding motor is fixedly connected to the end of the winding shaft.

At this time, the upper ironing cylinder and the lower ironing cylinder, which are clamped on both sides of the transfer paper and heated by high-temperature steam, are used to iron the wrinkled or uneven transfer paper, which is ironed flat at one time. This avoids the problem that the existing leveling device is only suitable for leveling transfer paper of shorter length. When the length of the transfer paper is greater than the length of the heating plate, the transfer paper needs to be fixed multiple times for leveling, which greatly reduces the work efficiency.
