Description

Technical Field

[0001] This utility model relates to the field of vacuum heat transfer technology, and in particular to a 3D vacuum heat transfer device with a quick mold changing function. Background Technology

[0002] 3D vacuum heat transfer printing is a technology that transfers patterns and text to the surface of a three-dimensional object using high temperature and high pressure. First, a heat transfer coating is applied to the surface of the three-dimensional object. Then, a heat transfer film with the pattern and text is placed on the coating. Under high temperature and high pressure, the ink layer on the transfer film melts and penetrates into the coating. After cooling, a stable pattern and text are formed. During the transfer process, multiple molds are often needed, requiring a 3D vacuum heat transfer printing device with a quick-change mold conversion function. First, a suitable irregular mold is selected according to the product shape. The mold is then installed into the equipment using a quick-change system. Next, the 3D product to be transferred is placed on the mold, and the heat transfer film with the pattern is covered on the product surface. The vacuum system is activated to create a vacuum. Then, the heating and pressure control systems work simultaneously, causing the pattern on the heat transfer film to be tightly transferred to the irregular surface of the 3D product under high temperature and high pressure. After the transfer is completed, the equipment returns to normal temperature and pressure, and the transferred product is removed to check the transfer quality.

[0003] A search revealed Chinese Patent Publication No. CN212151016U, which discloses a front-end automatic feeding 3D heat transfer device. This device includes a frame, a feeding mechanism, a receiving mechanism, and a transfer mechanism. The transfer mechanism includes a platform for placing the workpiece, a first drive mechanism for driving the platform up and down, a heat transfer plate positioned above the platform, a second drive mechanism for driving the heat transfer plate, and a clamping mechanism for holding the transfer film. The platform is connected to a vacuum device. The transfer mechanism also includes a feeding mechanism, which includes a mounting beam, a first gripper on the mounting beam, a second gripper on the mounting beam, and a third drive mechanism for driving the mounting beam to move back and forth between the first and second ends of the transfer mechanism. The first and second grippers are located on opposite sides of the transfer film along its transverse direction. While this invention can improve the processing accuracy of heat transfer printing, it does not solve the problem of cumbersome mold changes and the risk of incorrect placement during use, which affects production efficiency.

[0049] When the hot roller 24 malfunctions and needs to be replaced, rotate the rotating handle 206. The rotating handle 206 will drive the threaded rod 205 to rotate. Then the threaded rod 205 will rotate away from the threaded sleeve 202 and the baffle 201, and then away from the threaded hole 204 in the hot roller 24, until it leaves the threaded sleeve 203. At this time, the hot roller 24 can be replaced. After placing the new hot roller 24, similarly, rotate the rotating handle 206 to rotate the threaded rod 205 into the threaded sleeve 203 and the threaded sleeve 202. At this time, it can be used normally, realizing the effect of quickly replacing the hot roller 24 when it malfunctions.
