[0023] Example

[0024] See also Figure 1-4 A workpiece drying device comprises a closed drying chamber 1 and a hot air chamber 2. The drying chamber 1 is provided with an exhaust port. A plurality of drying blowing pipes 3 are arranged in sequence along the vertical direction in the drying chamber 1. The drying blowing pipes 3 are connected with a blowing nozzle 4 and a transmission worm gear 5. One end of the drying blowing pipe 3 is closed, and the other end is connected with a ventilation pipe 6 through a rotary joint. The ventilation pipe 6 is connected to the hot air chamber 2. An adjusting rod 7 is arranged on one side of the drying blowing pipe 3. The adjusting rod 7 is rotatably connected to the drying chamber and is connected with an adjusting motor (not shown in the figure). The transmission worm gear 5 corresponding to each drying blowing pipe 3 on the adjusting rod 7 is provided with a transmission worm 8 matching the transmission worm gear 5.

[0025] In this embodiment, a door is provided on the front side of the drying chamber 1. By opening the door, the workpiece to be dried can be placed in the drying chamber 1; the hot air chamber 2 is provided on the rear side of the drying chamber 1 and is separated from the drying chamber 1 by a partition for generating hot air; drying blowing pipes 3 are provided on the left and right sides of the drying chamber 1, and an adjusting rod is provided on each side for adjusting the blowing direction.

[0026] When in use, the hot air in the drying room enters the drying blow pipe 3 through the ventilation duct, and then is sprayed out from the spray nozzle to dry the workpiece; the adjusting motor drives the adjusting rod 7 to rotate, the transmission worm 8 rotates with the adjusting rod 7, and drives the drying blow pipe 3 to rotate through the transmission worm gear 5, and the blowing direction of the spray nozzle 4 can be adjusted, so as to adjust and change the hot air blowing direction according to the shape of the workpiece, the drying condition, etc., to meet different drying needs.

[0027] The device realizes linkage control of a plurality of drying spray pipes 3 by setting an adjusting rod, simplifies the structure and facilitates operation.

[0028] The drying blowing pipe 3 is connected to the ventilation pipe via a rotary joint. When the drying blowing pipe 3 rotates, the ventilation pipe does not rotate, thereby ensuring the normal flow path of the hot air.

[0029] The drying blowing pipe 3 is rotatably connected to the U-shaped frame 9, and adjacent drying blowing pipes 3 are connected by a scissor frame 10. One of the U-shaped frames 9 is fixed in the drying chamber 1 and is a fixed U-shaped frame, and the rest are movable U-shaped frames, one of which is connected to a lifting assembly. The adjusting rod 7 is provided with a keyway extending along its axial direction, and the transmission worm 8 is hollow and coaxially sleeved on the adjusting rod 7. A connecting key 11 matching the keyway is provided on the inner wall of the transmission worm 8. The transmission worm 8 is rotatably connected to a connecting plate 12, and the connecting plate 12 is connected to the U-shaped frame 9 where its corresponding drying blowing pipe 3 is located.

[0030] In this embodiment, the ventilation duct is fixed on the U-shaped frame 9 and connected to the hot air chamber 2 through a telescopic hose (not shown in the figure); the U-shaped frames 9 are connected at equal intervals through scissor arms, and the fixed U-shaped frame is located in the middle. When the lifting assembly drives the movable U-shaped frame connected to it to rise and fall, under the action of the scissor frame 10, the remaining movable U-shaped frames also move, so that the U-shaped frames always maintain equal spacing, thereby changing the gap between the U-shaped frames, and adjusting the blowing range of the drying spray pipe 3 according to the size and position of the workpiece, so that the drying spray pipe can perform concentrated blowing and drying on the workpiece.

[0031] The adjusting rod 7 drives the transmission worm 8 to rotate through the connecting key 11. When the movable U-shaped frame is raised or lowered, the connecting plate 12, the transmission worm 8, and the transmission worm wheel 5 are all raised or lowered synchronously therewith. Therefore, the transmission worm 8 and the transmission worm wheel 5 always remain in a meshing state, which will not affect the regulating effect of the adjusting rod 7 on the drying spray pipe 3.

[0032] Each U-shaped frame 9 is correspondingly provided with a scissor frame 10, and the scissor frame 10 includes a scissor arm 1 and a scissor arm 2 which are rotatably connected through a pin shaft 13 provided on the U-shaped frame 9, and the two ends of the scissor arm 1 are respectively rotatably connected to the ends of the scissor arm 2 of the adjacent scissor frame.

[0033] The lifting assembly includes a threaded rod 14 and a guide rod 15 . The threaded rod 14 is rotatably connected to the drying chamber 1 and is connected to a lifting motor (not shown in the figure). The guide rod 15 is fixedly connected to the drying chamber 1 .

[0034] The lifting motor drives the threaded rod 14 to rotate, so as to realize the lifting and lowering of the U-shaped frame 9 and the drying blowing pipe 3.

[0035] The hot air chamber 2 is provided with an air inlet 16 , and a heating resistance wire is provided inside the hot air chamber 2 .

[0036] The clean gas enters the hot air chamber 2 through the air inlet and is heated by the heating resistor wire, thereby forming hot air to enter the drying spray pipe 3. In actual use, the air inlet and the air outlet can be connected by a circulating fan to form a hot air circulation.

[0037] The drying chamber of this embodiment is also provided with a moisture discharge port (not shown in the figure).

[0038] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
