Description

Technical Field

[0001] The utility model relates to the technical field of hot stamping transfer printing, in particular to a high-efficiency cooling device for hot stamping transfer printing film. Background Art

[0002] Hot stamping transfer printing usually uses heat transfer, and the principle of heat transfer printing is similar to the transfer painting method. During heat transfer printing, the pattern is first printed on paper with disperse dyes and printing ink, and then the printed paper (also called transfer paper) is stored for use in the textile printing factory. When printing fabrics, after heat transfer printing, the transfer paper and the unprinted paper are pasted face to face and passed through the machine at about 210°C. At such a high temperature, the dye on the transfer paper sublimates and transfers to the fabric, completing the printing process. The hot stamping transfer printing method generally includes the steps of selecting the base film, printing ink, gluing, high-temperature baking, winding and fixing, hot pressing transfer, and separation and forming.

[0003] During the gluing process of the base film, the glue on the base film is in a softened state because the base film needs to be heated at a high temperature. When the base film is rolled up, it is easy to adhere to the adjacent base film, affecting the quality of transfer printing. Utility Model Content

[0028] See also Figures 1 to 4 As shown, an embodiment of the present application provides an efficient cooling device for hot stamping transfer printing film, which includes a frame and a printing portion 10, a cooling portion 20 and a winding portion 30 arranged on the frame, wherein:

[0029] The glue printing unit 10 is configured to apply glue printing to the base film 40 passing through;

[0030] The cooling section 20 is disposed obliquely above the printing section 10 and located near the winding section 30. The base film 40 after printing is introduced into the winding section 30 after passing through the cooling section 20. The winding section 30 is configured to wind up the cooled base film 40.

[0031] The cooling section 20 includes at least one cooling roller 21. After the gluing is performed, the base film 40 passes through all the cooling rollers 21 and is introduced into the winding section 30. The cooling roller 21 includes a cooling cavity 210, a cooling medium inlet and a cooling medium outlet. The cooling medium enters the cooling cavity 210 through the cooling medium inlet and flows out from the cooling medium outlet to cool the base film 40 that passes through the cooling roller 21.

[0032] Through the cooperation of the printing part 10, the cooling part 20 and the winding part 30, the base film 40 can be quickly cooled and solidified after gluing, avoiding the base film 40 from easily sticking to the adjacent base film 40 during winding, and also improving the working efficiency of the production line.

[0033] In one embodiment, the cooling roller 21 is rotatably mounted on the frame 50, and a first driving member 22 is provided in conjunction with each cooling roller 21. The fixed end of the first driving member 22 is fixedly mounted on the frame 50, and the driving end of the first driving member 22 is connected to the cooling roller 21. The first driving member 22 is configured to drive the cooling roller 21 to rotate along the frame 50.

[0034] The cooling roller 21 is driven to rotate by the first driving member 22 to ensure that the base film 40 can be cooled constantly and evenly during the cooling process, which helps to improve the cooling effect of the base film and product quality.

[0035] In one embodiment, the cooling section 20 includes two cooling rollers 21 spaced apart from each other. The base film 40 after the printing of the adhesive is passed through the two cooling rollers 21 in sequence and introduced into the winding section 30 .

[0036] By passing the base film 40 around the two cooling rollers 21 set at intervals in sequence, the contact area and time between the base film 40 and the cooling rollers 21 are increased, ensuring that the base film 40 is fully cooled and improving the cooling efficiency.

[0037] In one embodiment, the first driving member 22 includes a motor 220, a driving gear 221 and a transmission gear 222. The motor is fixedly mounted on the frame 50, the driving gear 221 is mounted on the rotating shaft of the motor 220, and the transmission gear 222 is mounted on the rotating shaft of the cooling roller 21. The driving gear 221 is meshed with the transmission gear 222.

[0038] Through the cooperation of the motor 220, the driving gear 221 and the transmission gear 222, a stable and precise power support is provided for the rotation of the cooling roller 21, thereby improving production efficiency and product quality.

[0039] In one embodiment, the cooling medium is either cooling water or cooling oil.

[0040] By setting the cooling medium to cooling water or cooling oil, not only can the good heat conduction capability of the cooling medium be utilized to quickly absorb the heat on the base film 40 and improve the cooling efficiency, but the cooling medium can also be easily replaced, thereby reducing the operating cost of the device.

[0041] In one embodiment, the efficient cooling device for hot stamping transfer printing film further includes a guide roller 60 mounted on the frame 50 , and the base film 40 is introduced into the guide roller 60 after passing through the cooling section 20 , and is then introduced into the winding section 30 through the guide roller 60 .

[0042] By providing the guide roller 60 , it is not only ensured that the base film 40 accurately enters the winding section 30 after cooling, but also facilitates improving the flatness of the base film 40 when winding, thereby ensuring the quality of the product.

[0043] In one embodiment, the two cooling rollers 21 are set at different heights, and one cooling roller 21 close to the guide roller 60 is located diagonally above the other cooling roller 21. The base film 40 passes through the diagonally above cooling roller 21 and the diagonally below cooling roller 21 in turn, and is then introduced into the guide roller 60.

[0044] By the base film 40 passing through the two cooling rollers 21 of different heights in sequence, the contact area between the base film 40 and the cooling rollers 21 during the conveying process is increased, thereby improving the cooling effect and cooling efficiency of the base film 40.

[0045] In one embodiment, the two cooling rollers 21 are arranged at the same height.

[0046] In one embodiment, the distance between the two cooling rollers 21 is adjustable.

[0047] By setting the distance between the two cooling rollers 21 to be adjustable, the contact time between the base film 40 and the cooling rollers 21 can be changed by adjusting the distance between the cooling rollers 21, so as to achieve the best cooling effect.

[0048] The above embodiments merely illustrate the basic principles and features of the present application. The present application is not limited by the above examples. Various changes and modifications may be made to the present application without departing from the spirit and scope of the present application. Such changes and modifications are intended to fall within the scope of the present application. The scope of protection claimed in the present application is defined by the appended claims and their equivalents.
