[0002] Automatic drying powder spray coating equipment is a kind of equipment used in industrial production lines. It is mainly used to spray powder coating evenly on the surface of workpieces, and solidify and adhere to the surface of workpieces through the drying process after spraying. Automatic drying powder spray coating equipment plays an important role in industrial production. It can realize efficient spraying production, improve coating quality, and also improve production efficiency.

[0011] Furthermore, a protective net is installed on the top of the installation groove.
[0012] Furthermore, the screw rod is threadedly connected to the movable block.
[0013] Furthermore, heat transfer oil is stored in the heat transfer pipe.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] Through the coordinated use of the heat pipe, insulation board, screw rod, synchronous pulley and motor, when the workpiece is dried and solidified and is waiting to be cooled, the motor is started, the motor drives the synchronous pulley to rotate, and the synchronous pulley drives another synchronous pulley to rotate through the synchronous belt, so that a pair of screw rods rotate at the same time. Since the screw rod is threadedly connected to the movable block, the movable block is driven to move upward when the screw rod rotates, and the movable block drives the heat insulation board to move into the placement groove.

At this time, the heat pipe releases the heat to preheat the drying box, which not only saves the energy consumed by heating, but also reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Among them, a slide groove 102 is provided on the top of the spray box 1, a slide rod 8 is installed in the slide groove 102, a slider 802 is slidably connected to the periphery of the slide rod 8, and a hook 801 is installed on the bottom end surface of the slider 802. The workpiece is hung on the hook 801, and the spray head 101 is opened to spray the workpiece.
[0031] Among them, a second slide groove 201 is provided on the top of the drying box 2, and one end of the slide rod 8 extends into the second slide groove 201. After the spraying is completed, the staff pushes the workpiece into the drying box 2 through the slide rod 8 for drying and curing.
[0032] Among them, a pair of motors 9 are installed on the top surface of the drying box 2, and the output ends of the pair of motors 9 are respectively connected to two of the synchronous pulleys 6. When the motor 9 is started, the motor 9 drives the synchronous pulley 6 to rotate, and the synchronous pulley 6 drives another synchronous pulley 6 to rotate through the synchronous belt, so that a pair of screw rods 301 rotate at the same time.
[0033] Among them, both ends of the drying box 2 are equipped with box doors 202 through hinges, and the box doors 202 can close the drying box 2 to prevent heat loss.
[0034] Among them, a protective net 702 is installed on the top of the installation groove 7, and the protective net 702 starts the protective function.
[0035] The screw rod 301 and the movable block 502 are threadedly connected.

[0037] The working principle of this embodiment:
[0038] First, hang the workpiece on the hook 801, open the spray head 101 to spray the workpiece, and after the spraying is completed, the staff pushes the workpiece into the drying box 2 through the slide rod 8 for drying and curing. When the workpiece is dried and cured and waiting to cool, start the motor 9, the motor 9 drives the synchronous pulley 6 to rotate, and the synchronous pulley 6 drives another synchronous pulley 6 to rotate through the synchronous belt, so that a pair of screw rods 301 rotate at the same time. Since the screw rod 301 is threadedly connected with the movable block 502, the screw rod 301 drives the movable block 502 to move upward when it rotates, and the movable block 502 drives the heat insulation board 501 to move into the placement groove 5. At this time, the heat transfer oil in the heat pipe 401 begins to absorb the heat in the drying box 2 and accelerates the drying box 2 The cooling rate of the temperature inside is then started again by the motor 9. According to the above steps, the heat insulation board 501 is moved into the placement slot 5 to keep the heat in the heat pipe 401 warm to avoid heat loss. The staff moves the next batch of workpieces into the drying box 2 and starts the motor 9 again. According to the above steps, the heat insulation board 501 is moved into the placement slot 5. At this time, the heat pipe 401 releases the heat to preheat the drying box 2. This not only saves the energy consumed by heating, but also reduces the production cost. When the heat of the heat-conducting oil in the heat pipe 401 is consumed to a certain extent, the motor 9 is started to move the heat insulation board 501 into the placement slot 5. Finally, the drying mechanism 701 is started to dry and solidify the workpieces.
