The utility model discloses a food packaging, printing and drying all-in-one machine, and relates to the technical field of food packaging and printing. The printing device comprises a workbench, the upper surface of the workbench is fixedly connected with a U-shaped supporting frame in a U shape, the top of the U-shaped supporting frame is fixedly provided with a drying assembly communicated with the interior of the U-shaped supporting frame, two second positioning rods are rotationally arranged between two vertical plates of the U-shaped supporting frame in a sleeved mode, and a printing mechanism is fixedly installed on the U-shaped supporting frame. The printing plate is sealed in the positioning box, on one hand, ink on the printing plate is prevented from being volatilized and dried up due to the drying effect of the drying assembly, the printing quality of food packaging bags is prevented from being affected, on the other hand, dust prevention is conducted on the printing plate, dust falling is avoided when the printing plate is not used, and the printing quality of the food packaging bags is improved. And therefore, the printing quality of the printing and drying all-in-one machine on food packaging bags is improved, and the practicability of the food packaging, printing and drying all-in-one machine is improved.

This utility model discloses a clothes drying component and a clothes drying machine, belonging to the technical field of clothes drying devices. The clothes drying machine includes a main unit, a drying rack, and a drying net module. The main frame of the drying rack is connected to the main unit via a lifting component. The main frame includes a first fixed rod and a second fixed rod spaced apart along its width. The drying net module includes a base, a drying net, and a net-pulling component. The first end of the drying net is connected to the base, and the second end is connected to the net-pulling component. The base is connected to the first fixed rod. The drying net module has a first state and a second state. When the drying net module is in the first state, the drying net is stored in the base, and the net-pulling component is separated from the second fixed rod. When the drying net module is in the second state, the drying net is unfolded, and the net-pulling component is connected to the second fixed rod. The drying net in this application can be unfolded along the width of the clothes drying machine. After unfolding, the drying net forms a large drying area and has good load-bearing capacity. When not in use, the drying net can be stored to avoid dust accumulation. The assembly method of the drying net module and the main frame is simplified.

This utility model discloses an air outlet structure for a heat storage electric heater, relating to the field of electric heating technology. It includes a heater body with two mounting slots inside. Guide blocks are slidably connected to each of the two mounting slots, and an air outlet frame is fixedly installed between the two guide blocks. A mechanism box one is fixedly installed on one side of the air outlet frame. Several rotating shafts are rotatably connected to the two adjacent sides inside the air outlet frame, and air guide plates are fixedly installed on the outer sides of each of the rotating shafts. The beneficial effects of this utility model are: with the setting of mechanism box one and mechanism box two, when the air direction needs to be adjusted, simply move the pull ring up or down to adjust the air guide plate to the required angle. Furthermore, by inserting the locking block into the corresponding slot, the angle can be fixed. This process facilitates adjusting the air direction according to individual needs during use, making adjustment easier.

This invention discloses a mine-use isolated operating platform, relating to the technical field of mine operating platforms. It includes a base, with two fixed seats fixed to one side wall of the base. An operating panel and adjustment knob are fixed to the top of the base, and a display platform is fixed to the top of the base. A display screen and indicator lights are fixed to one side wall of the display platform. The invention utilizes a first telescopic rod for support on the surface of a cover plate. To prevent workers from standing during operation of existing mine operating platforms, which can cause fatigue, a mounting plate at one end of the first telescopic rod is inserted into the fixed seats for support, allowing workers to sit on the cover plate for rest, improving work efficiency. Furthermore, to prevent dust accumulation on the surface after use if the operating platform is not covered promptly, avoiding the hassle of cleaning, a cover plate and sealing plate are used to cover the top of the workbench and the base, preventing dust from settling on the surface. This is highly practical.

The utility model discloses an invisible fan lamp capable of being stored in a dustproof mode, and relates to the field of invisible fan lamps, the invisible fan lamp comprises a hanging rod, a lamp body is installed at the bottom of the hanging rod, a lampshade is arranged at the bottom of the lamp body, the top of the lamp body penetrates through a bearing at equal angles to be connected with a shaft rod, and fan blades are fixed on the shaft rod. And fixing frames are installed at the top of the lamp body at equal angles, cover plates are fixed to the outer sides of the fixing frames, the cover plates cover the outer sides of the fan blades, and air spraying holes are formed in the cover plates at equal intervals. According to the invisible fan lamp capable of being stored in the dustproof mode, in the using process, after the fan blades are rotated out for use through centrifugation and the rotating speed is reduced, the reset springs drive the fan blades to be automatically stored and gathered, the cover plate can cover the surfaces of the fan blades, dust falling is avoided, when the fan blades are retracted into the cover plate, air can be sprayed to the surfaces of the fan blades through the air spraying holes, and the dustproof effect is further improved; therefore, the fan blades can be kept in a clean state during subsequent use.
