It has efficient, precise, and diverse printing capabilities and is widely used in many industries such as clothing, home furnishings, and decorations.

[0003] The dryer used in printing machines generates heat and blows it onto the substrate, which causes the ink to solidify quickly, ensuring the durability and stability of the printing effect; it also ensures the quality and color of the printed patterns, making the printed designs clearer and more complete, and improving the overall quality of the product.

[0004] Existing dryers have some or all of the following shortcomings: 1. They use a set of long electric heating tubes arranged side by side, which means that regardless of the size of the drying area, only the same power can be used for heating, resulting in serious heat waste; 2. They lack heat reflection devices, leading to severe heat loss and overheating of the dryer casing, resulting in high power consumption, low efficiency, and rapid aging of the wiring; 3. They lack air guiding devices, resulting in uneven hot air supply and slow airflow; 4. They are installed on the ground using support feet, which takes up space, makes cleaning inconvenient, and can easily tilt on uneven floors, leading to uneven heating. Utility Model Content

Each set of electric heating elements 4 can be independently controlled to start and stop. Each set of electric heating elements 4 includes multiple electric heating tubes 400 installed side by side. The independent start and stop control can be designed so that multiple electric heating tubes 400 in a set of electric heating elements 4 start and stop simultaneously, or it can be designed so that a single set of electric heating elements 4 starts and stops simultaneously. Each heating element 400 in component 4 can be started and stopped independently; depending on the size of the substrate, one or more heating components 4 can be turned on, which is practical and energy-saving, reducing heat waste; multiple air guide plates 5 are installed side by side in the housing cavity 100 above the heat reflector plate 3, and multiple air guide vanes 6 are installed side by side in the air outlet 200 of the fan 2, which divide the air outlet 200 into multiple small air outlets to control the air direction and increase the air speed; when in use, the dryer 13 is mounted on the printing machine 12, and the height is adjusted to keep the dryer 13 horizontal. Depending on the area of ​​the substrate to be dried, select one or all of the electric heating components 4 for heating; when the fan 2 is working, the air guide 6 guides the air from the air outlet 200 of the fan 2 to blow it quickly and evenly into the housing cavity 100, the air guide plate 5 guides the air from one end of the housing cavity 100 to the other end quickly and evenly, and the multiple air hole groups 300 make the air blow quickly and evenly from the housing cavity 100 to the electric heating tube 400 and the substrate, improving drying efficiency and saving energy.

[0049] In some embodiments, the height of the heat reflector 3 above the ground is less than or equal to the height of the air outlet 200 above the ground, which is beneficial to air flow; the angle between each air guide plate 5 and the heat reflector 3 is an obtuse angle, that is, the air guide plate 5 is inclined downward from one end of the air outlet 200 to the other end; each air guide plate 5 is located in the housing cavity 100 above the air outlet 200, and the above structure can improve the air flow speed.

[0050] In some embodiments, there are two sets of electric heating components 4, which are arranged side by side below the air holes. The power of one set of electric heating components 4 is greater than that of the other set. For example, the power of one set of electric heating components 4 can be one to several times that of the other set. When the flower area is small, the electric heating component 4 with lower power is turned on. When the flower area is large, the electric heating component 4 with higher power is turned on. When the flower area is extra large, both sets are turned on. The flower area represents the area to be dried.

[0051] In some embodiments, multiple air vent groups 300 are arranged side by side, each air vent group 300 including multiple air vents opened side by side, so that the cold air from the fan 2 is blown onto the heating element 400 and heated into hot air.

[0052] In some embodiments, an electrical box 7 is installed at one end of the housing 1, and a fan 2 is installed inside the electrical box 7. An air inlet 700 is opened at the bottom of the electrical box 7, and a dust cover 701 is installed on the air inlet 700 to reduce dust entry. A handle 702 is installed on the outside of the electrical box 7 to facilitate the movement of the operator. A box cover 704 is hinged to the electrical box 7 by two hinges 703 arranged side by side to facilitate the opening and closing of the electrical box 7.

Multiple clips 401 are installed on both sides of the housing 1, which are roughly U-shaped and elastic. One end of each heating element 400 is clamped in the clip, making installation and removal convenient and quick. The two heating elements 400 of two adjacent sets of heating components 4 can be connected by a fixing bracket 402, which is roughly U-shaped, to reduce vibration and prevent them from falling off.

[0055] In some embodiments, the heating element 400 is a U-shaped carbon fiber heating element, and the fan 2 is a cross-flow fan with a large airflow, which can blow the electric heating energy onto the substrate to the maximum extent and improve the drying efficiency; when the air flows, it can also dissipate heat to the electrical box 7 and the casing 1; the heat reflector 3 is a mirror stainless steel plate, which is heat-resistant and can increase the efficiency of reflecting heat energy; the air guide 6 is vertically set, and the air guide 6 can also be fixed by screws, and its installation angle can be adjusted to control the airflow direction.

The first suspension device 10 consists of two symmetrically arranged devices, each including a column 10a, a screw 10b threadedly connected to the column 10a, an adjusting nut 10c installed on the screw 10b, a U-shaped seat 10d installed at the lower end of the screw 10b, and a roller 10e hinged in the U-shaped seat 10d. The roller 10e is rotatably connected to the U-shaped seat 10d via a shaft. The U-shaped seat 10d can be inserted into one end beam of the printing machine 12. The distance between the dryer 13 and the substrate can be adjusted by the screw 10b and the adjusting nut 10c. The roller 10e facilitates the movement of the dryer 13 on the printing machine. The first suspension device 10 and the second suspension device 11 include a bracket 11a and wheels 11b mounted on the lower end of the bracket 11a by bolts or screws. Two or more wheels 11b are arranged side by side, and each wheel 11b can be placed on the plane at the other end of the printing machine 12. The wheels 11b facilitate the movement of the dryer 13 on the printing machine 12, reducing the resistance during movement. Changing the diameter or installation position of the wheels 11b can also adjust the distance between the dryer 13 and the substrate. The dryer 13 can be installed on the printing machine 12 through the first suspension device 10 and the second suspension device 11, reducing space occupation and making the movement and adjustment of the dryer 13 convenient.
