Technical Field

[0001] The invention relates to the technical field of printing machines, in particular to a packaging printing machine with a cooling roller. Background Art

[0002] A printing press is a machine for printing text and images. Modern printing presses are generally composed of mechanisms such as plate loading, inking, pressing, and paper feeding. Its working principle is: first, the text and image to be printed are made into a printing plate, which is then installed on the printing press. Then, ink is applied to the places where the text and image are on the printing plate by humans or the printing press, and then directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate.

[0017] The present invention provides a packaging printing machine with a cooling roller. It has the following beneficial effects:

[0018] The packaging printing press with cooling rollers is provided with three cooling rollers, and cooling water is passed through the cooling rollers to cool the cooling rollers. During use, the printer body heats up, causing the rollers to heat up, which will affect the viscosity and fluidity of the ink on the rollers, resulting in unstable printing quality, affecting the output and yield of the equipment. Therefore, three cooling rollers, shafts and two-way rotary joints are provided, and cooling water is passed through the cooling rollers to cool the cooling rollers, and then cool the ink on the top of the cooling rollers to solve the above problems. Since the inside of the roller is designed to be water-permeable, the temperature adjustment of the roller is sensitive and the response is fast. The cooling water enters the inside of the roller and directly exchanges heat with the roller, which improves the heat exchange efficiency.

[0019] The packaging printing machine with cooling roller controls the position of the cleaning component and the positioning mechanism by setting a control mechanism. When the equipment is not in use, the two-way rotary joint is exposed to the outside, and dust and impurities are easy to enter the two-way rotary joint and then enter the interior of the cooling roller, affecting the subsequent circulation of cooling water. Therefore, a cleaning component is set up to block the two-way rotary joint using the brush head position to solve the above problem. After using the equipment, by manually rotating the rotating rod, the rotating rod drives the brush head to clean the inside of the two-way rotary joint, reducing impurities inside the two-way rotary joint.

[0020] The packaging printing machine with a cooling roller has a clamping mechanism to fix and protect the water inlet pipe and the water outlet pipe. When cooling water is introduced into the cooling roller, the water inlet pipe and the water outlet pipe need to be connected to the two-way rotary joint. As the printing machine runs, the connection position of the water inlet pipe and the water outlet pipe with the two-way rotary joint is prone to loosening, resulting in local water leakage. Therefore, a clamping mechanism is provided to fix and protect the water inlet pipe and the water outlet pipe, and to press the top of the pipe to prevent the pipe from loosening.

[0021] The packaging printing machine with cooling rollers is equipped with a control mechanism and a positioning mechanism to block and clean the bidirectional rotary joint and fix the pipeline. Three cooling rollers that can be fed with cooling water are set in the equipment. The three cooling rollers cooperate with four rubber rollers to complete the printing work. The cooling water cools the cooling rollers, and then cools the ink on the top of the cooling rollers to avoid the equipment temperature being too high and affecting the ink properties. In the process of passing the cooling water, the water inlet pipe and the water outlet pipe are fixed and protected to prevent the fixed position from loosening. After the work is completed, the brush head is used to block or rotate and clean the bidirectional rotary joint to reduce the impurities in the bidirectional rotary joint. The purpose of facilitating the blockage protection and cleaning of the bidirectional rotary joint and fixing and protecting the pipeline is achieved. BRIEF DESCRIPTION OF THE DRAWINGS
