Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of traction mechanisms for transfer printing equipment, specifically a traction mechanism for transfer printing equipment. Background Technology
[0002] Heat transfer, also known as thermal sublimation, is a special process in which any image, such as a portrait or landscape, is printed onto ordinary or high-precision paper using heat transfer ink. Then, the image is heated to a certain temperature within minutes using appropriate heat transfer equipment, transferring the image from the paper to materials such as ceramic cups, plates, slabs, clothing, and metal in a lifelike manner.
[0003] However, during the transfer process, the traction device is sometimes too loose or too tight, which directly affects the printing quality. After long-term use, the traction rod is covered with glue or ink, which requires regular cleaning. Manual cleaning is time-consuming and laborious. Therefore, we propose a traction mechanism for the transfer equipment. Utility Model Content
[0004] The purpose of this utility model is to provide a traction mechanism for a transfer printing device to solve the problems mentioned in the background art, such as the traction device sometimes being too loose or too tight, which directly affects the printing quality, and the time-consuming and laborious process of manually cleaning impurities on the traction rod.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a traction mechanism for a transfer printing device, comprising identical supports on both the left and right sides, the supports being cuboids, a track groove being formed in the middle of the inner cavity at the upper end of the supports, a sliding rod being horizontally installed in the inner cavity of the track groove, a slider being slidably installed on the sliding rod, a cylinder being fixedly installed on the bottom surface of the slider, a cleaner being installed on the telescopic shaft of the cylinder, a buffer being installed at the bottom end of the inner cavity of the supports, and a traction rod being horizontally installed on the buffer.
[0006] Preferably, the support has a discharge port through the left and right side walls in the middle.
[0007] Preferably, the inner cavity sidewall of the slider is provided with a drive wheel, and the buffer includes a damping spring and a clamping shaft. A driver is installed in the middle of the inner cavity of the clamping shaft, the damping spring is installed on the left and right sides of the clamping shaft, and the traction rod is fixedly installed on the driver.
[0008] Preferably, the cleaner includes: a hydraulic cylinder, grippers, a short rod, and a scraper. The grippers are semi-arc-shaped. The short rod is rotatably mounted on the output shaft of the hydraulic cylinder. A T-shaped shell is fixedly mounted on the side wall of the hydraulic cylinder. Rotary shafts are installed through the left and right sides of the T-shaped shell. The middle part of the grippers is rotatably mounted on the rotating shafts, and the top of the grippers is rotatably mounted on the bottom end of the short rod.
[0009] Preferably, the scraper is provided with bolts on its sidewall, and the scraper is threadedly installed in the bottom cavity of the gripper.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1) The device is equipped with a buffer. When the traction rod is working, the printing paper will be pulled. If the traction force is too large or too small, the printing paper will become tight or loose, making it difficult to pull the printing paper. The damping spring has a certain buffering capacity, which can push the traction rod to a suitable position to avoid being too loose or too tight. The device has a simple structure and is easy to use.
[0012] 2) The device is equipped with a cleaner. During printing, the traction rod is easily covered with glue or ink. If this is not cleaned for a long time, it will affect the traction. The hydraulic cylinder pushes down, which drives the opening and closing of the gripper. When the gripper reaches the appropriate position of the traction rod, the hydraulic cylinder retracts, the gripper clamps the traction rod slider and moves, and the rotating scraper of the traction rod scrapes off the dirt on the surface.
