The end gear 5-9 and the transmission gear 5-6 are complete gears that are always in meshing, and the gear shaft 5-7 on which the transmission gear 5-6 is arranged is provided with a first torsion spring 5-8, which is used to deform under force when the driving gear 5-5 is in the transmission state, so as to drive the gear shaft 5-7 on which the transmission gear 5-6 is arranged to rotate in the reverse direction through the elastic reaction force when the driving gear 5-5 is in the non-transmission state, and then drive the power input shaft to synchronously rotate in the reverse direction through the meshing transmission of the transmission gear 5-6 and the end gear 5-9, and then make the three rotating shafts 5-1 synchronously rotate in the reverse direction through the transmission belt 5-11.

[0043] As shown in Figure 2 , the rotating power source is a driving motor 5-10 mounted on the rear side wall of the box body 1, and the output shaft of the driving motor 5-10 penetrates through the rear side wall of the box body 1 and is in transmission connection with the driving gear 5-5.

[0044] As shown in Figures 4-6 , the reciprocating swinging direction of the placement disc 3 is the left-right direction, the placement disc 3 comprises a bottom plate 3-1, and the left and right sides and the rear side of the placement disc 3 are provided with fixed side plates 3-2, and the front side of the placement disc 3 is rotatably provided with a movable side plate 3-3, the movable side plate 3-3 is arranged opposite to the box door 2, and the movable side plate 3-3 has an opening station for opening to put the stud into the placement disc 3 and has a closing station for closing to be limited in the placement disc 3 together with the fixed side plates 3-2 on the left and right sides and the rear side. In order to facilitate the control of the opening and closing state of the movable side plate 3-3, a damping ring 3-4 is arranged at the position where the movable side plate 3-3 is rotatably mounted.

Each ramp 3-8 has an inclined surface to buffer and guide the double-ended studs rolling within the placement tray 3. Mounting rods 3-5 are respectively installed at the left and right ends of the placement tray 3. A stop 3-7, extending above the placement tray 3, is mounted on the mounting rod 3-5 to prevent the double-ended studs from jumping out. The stop 3-7 corresponds to the ramps 3-8. In this embodiment, the mounting rod 3-5 is fixed, while the stop 3-7 is rotatably mounted on the mounting rod 3-5. A second torsion spring 3-6 is also installed on the mounting rod 3-5.

The frame plate is rotatably mounted on the mounting rod 3-5, and the frame bars are connected to the frame plate, extending above the ramps 3-8.

[0046] like Figure 6 As shown, a collection box 6 is fixedly connected below each placement tray 3. The collection box 6 is located above the rotating shaft 5-1 and between the two sets of connecting rods 5-3. Figure 4 As shown, a drain hole 3-1-1 is provided on the base plate 3-1. During the baking process of the double-ended studs, the liquid dripping from the surface of the double-ended studs can leak through the drain hole 3-1-1 and enter the collection box 6. Each collection box 6 is connected to a suction pipe 7, which extends out of the box body 1 and is connected to a pump 9. A collection tank 8 is also provided on the outer wall of the box body 1. The liquid pumped by the pump 9 is discharged into the collection tank 8 for collection. By extracting the liquid, the material coated on the double-ended studs can be prevented from not being fully dried, thus avoiding waste of the soaking solution. In addition, a temperature control fan 10 is also installed on the rear side wall of the box body 1.

[0047] The working principle of the baking device for double-ended studs in this invention is as follows:

[0048] During operation, open the front door 2, rotate the movable side plate 3-3 installed on the placement tray 3 to open the movable side plate 3-3 at a certain angle, then rotate the baffle 3-7 to compress the second torsion spring 3-6. When the baffle 3-7 is rotated open, the two baffles 3-7 move away from each other. Then place the double-headed studs to be baked in the placement tray 3, and then release the baffle 3-7 to retract the second torsion spring 3-6, so that the two baffles 3-7 are located on the upper side of the placement tray 3, thereby forming a blockage for the double-headed studs and preventing them from falling off when shaken.

[0049] When the movable side plate 3-3 is closed, the driving motor 5-10 is controlled to work, the driving motor 5-10 drives the driving gear 5-5 to rotate, when the driving gear 5-5 and the transmission gear 5-6 are engaged, the transmission gear 5-6 drives the end gear 5-9 to rotate, so that the synchronous wheels 5-4 rotate at the same time, at this time, the first torsional spring 5-8 is compressed in one direction. At this time, the synchronous wheel 5-4 drives the rotating shaft 5-1 to rotate, when the rotating shaft 5-1 rotates, the rotating disc 5-2 installed on the rotating shaft 5-1 rotates at the same time, when the rotating disc 5-2 rotates in one direction, the rotating disc 5-2 simultaneously pulls one of the connecting rods 5-3 to move downward, and the other connecting rod 5-3 moves upward, so that the placing disc 3 is in an inclined state, at this time, the double-headed studs in the placing disc 3 slide on the slope plate 3-8 from one side to the other side, and then the double-headed studs are alternated, and when the driving gear 5-5 and the transmission gear 5-6 are disengaged, the first torsional spring 5-8 drives the transmission gear 5-6 to rotate in the opposite direction, so that the rotating shaft 5-1 rotates in the other direction, so that the placing disc 3 inclines in the other direction, so as to shake and alternate the double-headed studs, so that the double-headed studs are more uniform during drying, the drying efficiency is faster, and the work efficiency of the corrosion prevention treatment is improved.

[0050] When the equipment is drying, the excess liquid on the surface of the stud can fall into the liquid collecting box 6 through the liquid leakage hole 3-1-1 on the placing disc 3, then the pump 9 can be controlled to work, so that the pump 9 pumps out the liquid in the liquid collecting box 6 and delivers it to the collection box 8, so as to collect the excess liquid, avoid too much liquid, and cause waste of liquid.

[0051] The present application controls the left-right reciprocating swing of the placing disc 3, and then makes the studs in the placing disc 3 roll left and right, so that the stacked studs are in a moving pile, and the studs stacked at the bottom move from the bottom to the upper side under the swing of the placing disc 3, so that they are in a uniform state during baking, avoiding the bottom not being fully baked and the upper side being over-baked during baking, thereby causing the surface material to crack and affecting the material, so that the baking quality of the equipment and the quality of the studs are improved.
