Description

Technical Field

[0001] The utility model relates to a printing press, in particular to a heating box structure of a printing press. Background Art

[0002] The printing press uses fluid ink with strong fluidity. The ink is transferred to the graphic part of the printing plate through the ink fountain roller and the anilox roller and is inked. Then, the printing pressure is applied by the impression cylinder to transfer the ink on the printing plate to the printing substrate, and finally the printing process is completed through drying. The printing press includes a heating box, which supplies heat source to the printing press for supplying the working temperature of the printing material and performing subsequent drying and other operations. The existing heating method of the heating box is mostly a heating rod structure. The heating method of the heating rod structure has slow heating speed, unstable temperature control and high energy consumption. As a result, the existing heating box cannot supply a stable working temperature to the printing press, ultimately affecting the processing quality and processing efficiency of the printing press.

[0008] It is further set that: it further includes: a waste heat heating cavity, which is set to communicate with the heating area; an air inlet pipe is installed on the air inlet of the fan, and the waste heat heating cavity is communicated with the air inlet pipe.

[0009] By adopting the above technical solution, part of the temperature in the heating zone is transferred to the air inlet duct through the waste heat heating chamber, so that the airflow can be heated in the air inlet duct path, thereby realizing the waste heat recovery and reuse of the heating zone, and further improving the heating speed of the heating box and reducing energy consumption.

[0010] It is further configured as follows: it includes a waste heat shell and a connecting shell for forming a waste heat heating chamber, the connecting shell surrounds the outer periphery of the heating coil and is sealed with the air outlet duct, a heat conduction chamber is formed between the inside of the connecting shell and the air outlet duct, and the heat conduction chamber is communicated with the waste heat heating chamber.

[0011] By adopting the above technical solution, the surrounding heat-conducting cavity can collect the excess heat released from the heating coil to the greatest extent, and bring the heat into the waste heat heating cavity through the negative pressure formed in the waste heat heating cavity, so as to achieve the purpose of waste heat heating.

[0012] It is further configured as follows: it includes an air inlet, the air inlet connects the waste heat heating chamber with the outside world, and a check valve is installed on the air inlet to limit the airflow from the waste heat heating chamber to the outside world.

[0013] By adopting the above technical solution, the setting of the check valve can reduce the heat loss in the waste heat heating chamber to a certain extent, thereby achieving a better waste heat heating purpose.

[0014] It is further configured as follows: the fan includes an impeller housing, an impeller shaft rotatably arranged on the impeller housing, and a motor; the output shaft of the motor is provided with a plurality of left transmission blocks, the impeller shaft is provided with a plurality of right transmission blocks, the left transmission blocks and the right transmission blocks are staggered and inserted to form a steering linkage between the two, and a heat dissipation fan is provided on one side of the left transmission block and the right transmission block.

[0015] By adopting the above technical solution, the motor drives the impeller shaft to rotate through the cooperation of the left transmission block and the right transmission block, and the left transmission block and the right transmission block are cooled by the provided heat dissipation fan to prevent the high temperature in the impeller housing from being transmitted to the motor through the impeller shaft, thereby ensuring the working environment and service life of the motor. In addition, the provided left transmission blocks and the right transmission blocks can maximize the heat dissipation area to improve the heat dissipation effect.

[0016] In summary, the utility model has the following beneficial effects: the utility model heats up quickly, has stable temperature and consumes less energy. BRIEF DESCRIPTION OF THE DRAWINGS
