Limiting rods 33 adapted to the limiting holes 27 are fixedly installed at the rear sides of the driving blocks 32 and at the top and bottom of the threaded rod 31;

[0027] During the use by the staff, a plurality of placing racks 21 are taken out as needed and placed outside the mounting blocks 26 through the mounting openings at the bottoms of the placing racks 21. Then manually rotate the knob 34 to drive the rotation of the threaded rod 31. The threaded rod 31 drives the driving block 32 to slide backward inside the placing rack 21. The driving block 32 drives the two limiting rods 33 to pass through the communication holes and be inserted into the limiting holes 27 to limit the placing rack 21, so as to install another placing rack 21 on its top, which is convenient for the staff to disassemble the placing rack 21.

[0028] The adjusting component 40 includes two rotating seats 41 arranged on the top of the base 10 and located on the front and rear sides of the placing rack 21. A rotating rod 42 is commonly penetrated and rotatably connected to the inside of the two rotating seats 41 on the same side. Cam 43 are sleeved on the outer edges of the rotating rod 42 near the left and right ends. A rotating gear 44 is fixedly installed at the left end of the rear rotating rod 42. Adjusting rods 45 are commonly fixedly installed on the two cams 43 on the same side. A guide air plate 46 is sleeved on the surface of the adjusting rod 45;

[0029] After the device adjustment is completed, the drying device 50 starts to work, dissipating heat upward through the connection holes 60. The cylinder 48 starts to work, controlling the reciprocating movement of the rack 47. At this time, the rotating rod 42 can be driven to rotate by a certain angle by rotating the gear 44. The two rotating rods 42 are driven to rotate through the rotating groove wheel 49 and the belt. The rotating rod 42 controls the reciprocating rotation of the adjusting rod 45 through the cam 43. The adjusting rod 45 drives the air deflector 46 to perform an arc-shaped reciprocating rotation, so that the hot air is reciprocally blown up and down along the action of the air deflector 46 to dry the paper tray.

[0030] Support legs are fixedly installed at the bottom of the base 10 near the four corners. The drying device 50 is arranged at the bottom of the base 10, and a plurality of connection holes 60 are opened inside the base 10.

[0031] Mounting openings adapted to the mounting blocks 26 are opened at the bottom of the placement rack 21 near the left and right sides. Two connecting blocks are fixedly installed at the bottom of the limiting member 25, and connecting grooves 28 for the connecting blocks to slide back and forth are opened at the top of the placement rack 21.

[0032] A knob 34 for driving the rotation of the driving threaded rod 31 is rotatably arranged on the front side of the placement rack 21, and communication holes through which the limiting rods 33 can pass are opened inside the placement rack 21.

[0033] A rack 47 is meshed with the bottom of the rotating gear 44. A support block is fixedly installed on the left side of the base 10, and a cylinder 48 for driving the front and back movement of the rack 47 is fixedly installed on the top of the support block.

[0034] A rotating groove wheel 49 is fixedly installed on the outer edge of the rotating rod 42 and on the left side of the cam 43. A belt is sleeved on the outside of the two rotating groove wheels 49, and the two rotating groove wheels 49 are connected by belt drive.

[0035] The working principle of the multi-layer paper tray bracket provided by the present utility model is as follows:

[0036] The first step: During the use process, the staff takes out a plurality of placement racks 21 as needed, places them outside the mounting blocks 26 through the mounting openings at the bottom of the placement racks 21, and manually rotates the knob 34 to drive the threaded rod 31 to rotate. The threaded rod 31 drives the driving block 32 to slide backward inside the placement rack 21. The driving block 32 drives the two limiting rods 33 to pass through the communication holes and be inserted into the limiting holes 27 inside to limit the placement rack 21, so as to install another placement rack 21 on its top, facilitating the staff to disassemble the placement rack 21.

[0037] Step 2: Place the just-processed paper tray on the top of the placement rack 21, manually rotate the rotation handle 23 to drive the double-threaded screw rod 22 to rotate. The double-threaded screw rod 22 drives the moving block 24 to move inside the moving port. The moving block 24 drives the limiting member 25 to move closer to the center. The limiting member 25 fits on the surface of the paper tray to limit paper trays of different sizes, greatly increasing the practicality of the device.

[0038] Step 3: The drying device 50 starts to work and dissipates heat upward through the connection hole 60. The air cylinder 48 starts to work to control the reciprocating movement of the rack 47. At this time, the rotating rod 42 can be driven to rotate by a certain angle by rotating the gear 44. The two rotating rods 42 are driven to rotate by the rotating grooved pulley 49 and the belt. The rotating rod 42 controls the reciprocating rotation of the adjusting rod 45 through the cam 43. The adjusting rod 45 drives the air deflector 46 to rotate in an arc reciprocating manner, so that the hot air is reciprocally blown up and down along the action of the air deflector 46 to dry the paper tray.

[0039] Compared with the related technology, the multi-layer paper tray provided by the present utility model has the following beneficial effects:

[0040] Through the mutual cooperation of the various components of the device, it is placed on the outside of the mounting block 26 through the mounting port at the bottom of the placement rack 21. When the knob 34 is manually rotated, the threaded rod 31 is driven to rotate. The threaded rod 31 drives the driving block 32 to slide backward inside the placement rack 21. The driving block 32 drives the two limiting rods 33 to pass through the communication hole and be inserted into the limiting hole 27 inside to limit the placement rack 21, thereby installing another placement rack 21 on its top, which is convenient for the staff to disassemble the placement rack 21. The operation is simple and convenient, greatly increasing the practicality of the device.

[0041] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
