TECHNICAL FIELD
[0001] The present application relates to the technical field of printing product drying equipment, in particular to a vertical printing drying equipment. BACKGROUND
[0002] Printing is a technology that transfers ink to the surface of materials such as paper, fabric, plastic, leather, etc. through processes such as plate making, ink application, and pressure, to batch copy the content of the original. Nowadays, printing is generally ink printing. Ink printing has realistic colors and is not easy to fade after drying, and can be preserved for a long time. However, the ink of the just printed material is not dry, and cannot be overlapped. Overlapping not only makes the image on the material distorted, but also contaminates each other, making the entire material dirty, and even unusable. Currently, the just printed product generally needs to be dried to ensure processing efficiency.
[0003] However, the existing drying equipment usually uses electric heating wires or infrared lamp tubes as heat sources, and transfers heat to the printed material through natural convection or forced convection. However, no heat recycling device is provided, and a large amount of heat is lost during work, resulting in high energy consumption. CONTENT OF THE UTILITY MODEL
[0004] In view of the deficiencies of the prior art, the vertical printing drying equipment provided by the present application has the advantages of reducing power consumption, and solves the problem that the existing drying equipment usually uses electric heating wires or infrared lamp tubes as heat sources, and transfers heat to the printed material through natural convection or forced convection. However, no heat recycling device is provided, and a large amount of heat is lost during work, resulting in high energy consumption.
[0005] To achieve the above purpose, the present application provides the following technical scheme: a vertical printing drying equipment, comprising a box body, a suction box is fixedly connected to the bottom end of one side of the box body, a plurality of suction fans arranged in a straight line array are fixedly connected to the suction box penetrating one side of the box body, two air outlet pipes arranged in a mirror image are fixedly connected to the upper end of the suction box, a connecting pipe is fixedly connected to the upper end of each of the two air outlet pipes, a preheating box is fixedly connected to one side of the box body, two heat exchangers arranged in a mirror image are fixedly connected to the inside of the preheating box, four axial flow fans arranged in a straight line array are fixedly connected to the end of the preheating box away from the box body, an air inlet pipe is fixedly connected to one side of the upper end of the preheating box, a hot air box is fixedly connected to the top end of one side of the box body, a plurality of heating pipes arranged in a straight line array are fixedly connected to the inside of the hot air box, and a plurality of air outlet grooves arranged in a straight line array are formed in the end of the hot air box penetrating the box body.
[0006] Through the above scheme, the hot air in the box body is extracted and circulated through the cooperation of the air extraction box and the air extractor. The extracted hot air is sent into the heat exchanger in the preheating box through the connecting pipe to recover heat. The heat exchanger in the preheating box preheats the incoming fresh air using the recovered hot air, reducing the energy consumption required for subsequent heating. The heating pipe in the hot air box further heats the preheated air to ensure that the hot air temperature entering the box body is moderate and uniform. Through the synergistic effect of preheating and heating, the drying process is more efficient and energy-saving. The hot air box is provided with a plurality of air outlet slots arranged in a straight line at one end of the box body. This design allows hot air to be uniformly blown into the box body, achieving hot air circulation. Uniform hot air distribution ensures that each part of the printing material is fully dried, avoiding the problem of local overheating or insufficient drying. The device has heat recovery and recycling, preheating between heating, and reduces energy consumption during drying.
[0007] Further, the output ends of the two heat exchangers are fixedly connected with exhaust pipes, and the exhaust pipes away from the heat exchangers are fixedly connected with the air inlet pipes.
[0008] Through the above scheme, the heat exchanger can recover and utilize waste heat. Hot air passes through the heat exchanger, and after heat is released in the heat exchanger, the hot air enters the air inlet pipe through the exhaust pipe, along with the preheated air, and is heated in the heating box and enters the box body.
[0009] Further, the inside top of the box body is fixedly connected with a mounting seat, the inside top of the mounting seat is fixedly connected with a reflecting plate, and the inside bottom of the mounting seat is fixedly connected with a plurality of infrared lamp tubes arranged in a straight line.
[0010] Through the above scheme, the infrared lamp tubes can emit infrared radiation, which can directly act on the surface of the printing material to quickly heat and dry the material. The reflecting plate can reflect the heat radiation emitted by the infrared lamp tubes to ensure that the heat is more concentrated on the printing material, reducing heat loss and further improving drying efficiency.
[0011] Further, a plurality of first rotating shafts arranged in a straight line are rotatably connected to the upper end of one side of the box body, and a plurality of driven rotating rollers are fixedly connected to the outer walls of the second rotating shafts.
[0012] Through the above scheme, the driving rotating roller and the driven rotating roller are used to mount the PET film to be dried, and the PET film is sleeved on the outer walls of the driving rotating roller and the driven rotating roller at both ends, and the linear array of the driving rotating roller and the driven rotating roller ensures uniform rotation of the printing material during drying, and more uniform drying effect is achieved.
[0013] Further, a plurality of motors are fixedly connected to one side of the box in a linear array, and the output ends of the plurality of motors are fixedly connected to the first rotating shaft through a shaft coupling.
[0014] Through the above scheme, the motor is directly connected to the first rotating shaft through the shaft coupling, ensuring stable transmission of power, and each motor can be independently controlled, and the operator can adjust the rotating speed of the motor according to actual needs, so as to control the rotating speed of the printing material, which helps to achieve more uniform drying effect.
[0015] Further, the box is rotatably connected to the box door through a hinge on both sides, and the box door is fixedly connected to a handle on one side of the surface.
[0016] Through the above scheme, the box door is connected to the box through the hinge, which can be easily opened and closed, and the printing material can be placed and taken out. During the drying process, closing the box door can ensure that the heat and airflow inside the equipment are not leaked, thereby maintaining a stable drying environment. Closing the box door can also prevent the operator from accidentally contacting the high-temperature components, ensuring the safety of the operation.
[0017] Further, the two connecting pipes are fixedly connected to the input end of the heat exchanger away from the air outlet pipe.
[0018] Through the above scheme, the air outlet pipe is usually used to discharge hot air generated during the drying process, and the hot air still contains a certain amount of heat. By introducing the hot air into the heat exchanger through the connecting pipe, the heat can be recovered and reused. The recovered heat can be used to preheat the air entering the drying chamber, so that it can reach the required drying temperature more quickly, which helps to shorten the drying time and improve the production efficiency.
[0019] Further, the air inlet pipe is fixedly connected to the hot air tank away from the preheating tank.
[0020] Through the above scheme, the air inlet pipe is used to introduce the preheated air in the preheating tank into the hot air tank for further heating of the air.

[0036] The working principle of the above embodiment is as follows:
[0037] The operator first opens the box door 22, sets the two ends of the PET film to be dried on the outer wall of the driving roller 18 and the driven roller 21 respectively, closes the box door 22, starts the motor 19, and the motor 19 drives the first rotating shaft 17 and the driving roller 18 to start rotating through the shaft coupling.

The heat exchanger 7 preheats the fresh air entering by using the recycled hot air, which improves the utilization efficiency of heat energy. The hot air circulation, infrared drying and air extraction in the above steps work cooperatively with the heat recovery system to form a complete drying cycle. The operator can adjust the rotating speed of the motor 19, the power of the heating pipe 11 and the working strength of the air extractor 3 to control the drying speed and temperature.
