Description

Technical Field

[0001] This utility model relates to the technical field of cooling equipment for printing machines, and specifically to a cooling device for a heat transfer printing machine. Background Technology

[0002] Heat transfer printing is a new printing and dyeing process that has gradually emerged internationally in recent years. First, using advanced printing technology and special dyes, all the desired patterns and designs are printed onto special paper to create transfer printing paper with various patterns. Then, on a transfer printing machine, the side of the transfer printing paper with the printed pattern is pressed tightly against the fabric to be printed. Through heat and pressure, the dye on the printing paper sublimates and transfers to the fabric, forming the desired patterns on the fabric.

[0003] The fabric after heat transfer printing still has a certain residual temperature. At this time, the fabric has not cooled down sufficiently, which makes the printed pattern unstable and affects the printing quality. For example, a cooling device for a heat transfer printing machine disclosed in authorization announcement number CN221718121U cools the printed fabric by setting a cooling plate. The temperature distribution of low temperature in the middle and high temperature on both sides helps to form an airflow that moves to both sides.

[0004] The temperature distribution of the above structure, which is low in the middle and high on both sides, will cause uneven cooling of the printed fabric, which can easily lead to printing deformation. In addition, the airflow that moves to both sides is formed by the temperature distribution of the middle and high on both sides, and the airflow is slow and the cooling efficiency is low. Utility Model Content

[0005] To address the aforementioned technical deficiencies, this invention provides a cooling device for a heat transfer printing machine, which can uniformly and efficiently cool the printed fabric.

[0006] This utility model discloses a cooling device for a heat transfer printing machine, including a housing. A first partition is horizontally arranged in the middle of the housing. A second partition is horizontally arranged inside the housing above the first partition. The first and second partitions divide the housing into a first cavity, a second cavity, and a third cavity from top to bottom. A material inlet is provided on the front side of the first cavity, and a material outlet is provided on the rear side of the first cavity. Cooling pipes are horizontally spaced from left to right in the second cavity, with the front and rear ends of the cooling pipes passing through the housing respectively. A first mounting hole is evenly arranged along the front-back and left-right directions on the first partition. A second mounting hole is provided on the second partition at the position corresponding to the first mounting hole. A ventilation pipe is provided between the first mounting hole and the corresponding second mounting hole. The upper end of the ventilation pipe is sealed and fixed in the second mounting hole, and the lower end of the ventilation pipe is sealed and fixed in the first mounting hole. An air inlet is provided on the third cavity, and the air inlet is connected to the air outlet of an air pump through a pipe.

[0007] The principle of the above technical solution is as follows: the fabric after heat transfer enters from the feed port and exits from the discharge port. Cooling fluid flows in the cooling pipe. The specific type of cooling fluid used in the cooling pipe is not the content to be protected by the applicant. The second chamber is filled with cooling water. The cooling water is cooled by the cooling fluid in the cooling pipe. The air pump pumps air into the third chamber, creating positive pressure in the third chamber. This causes the air in the third chamber to flow into the ventilation pipe. The air is cooled by the cooling water as it flows through the ventilation pipe and then blows evenly onto the fabric, providing uniform and efficient cooling to the fabric.

[0008] Preferably, the distance between adjacent ventilation ducts is 5 cm and the inner diameter of the ventilation duct is 2 cm. This ensures that the density of the ventilation ducts is not too sparse and that the inner diameter of the ventilation duct is not too small, thus guaranteeing uniform and effective cooling of the fabric.

[0009] The cooling device for a heat transfer printing machine obtained by this utility model has the following advantages: through the uniformly distributed ventilation pipes, in conjunction with the cooling pipes and cooling water in the second cavity, cooling air can be blown out evenly from the ventilation pipes, so as to cool the fabric evenly and efficiently.

[0015] Example 1:

[0016] like Figure 1 , 2As shown in Figures 3 and 4, this utility model discloses a cooling device for a heat transfer printing machine, including a housing 1. A first partition 5 is horizontally arranged in the middle of the housing 1. A second partition 4 is horizontally arranged inside the housing 1 above the first partition 5. The first partition 5 and the second partition 4 divide the housing 1 from top to bottom into a first cavity, a second cavity, and a third cavity. A feed inlet is provided on the front side of the first cavity, and a discharge outlet is provided on the rear side of the first cavity. Cooling pipes 3 are horizontally spaced from left to right inside the second cavity. The front and rear ends of the cooling pipes 3 pass through the housing 1, respectively. Body 1, Partition 5 has No. 1 mounting holes evenly arranged along its front-back and left-right directions. Partition 4 has No. 2 mounting holes at the corresponding positions of No. 1 mounting holes. A ventilation pipe 6 is arranged between No. 1 mounting holes and the corresponding No. 2 mounting holes. The upper end of the ventilation pipe 6 is sealed and fixed in the No. 2 mounting hole, and the lower end of the ventilation pipe 6 is sealed and fixed in the No. 1 mounting hole. The distance between adjacent ventilation pipes 6 is 5 cm, and the inner diameter of the ventilation pipe 6 is 2 cm. A third cavity has an air inlet 2, which is connected to the air outlet of the air pump through a pipe.

[0017] The principle of the above technical solution is as follows: the fabric after heat transfer enters from the feed port and exits from the discharge port. Cooling fluid flows in the cooling pipe 3. The specific type of cooling fluid used in the cooling pipe 3 is not the content to be protected by the applicant. The second cavity is filled with cooling water. The cooling water is cooled by the cooling fluid in the cooling pipe 3. The air pump pumps air into the third cavity, creating positive pressure in the third cavity. This causes the air in the third cavity to flow into the ventilation pipe 6. The air is cooled by the cooling water as it flows through the ventilation pipe 6, and then blows evenly onto the fabric, providing uniform and efficient cooling to the fabric.
