The diameter of the third gear 63 is smaller than that of the second gear 62, and the diameter of the third gear 63 is smaller than that of the first gear 61, so that the number of teeth of the third gear 63 is smaller than that of the first gear 61, and the effect of speed reduction is achieved through the second gear 62 and the third gear 63. The hook part 42 is further fixed with a baffle 7, the baffle 7 is positioned below the first gear 61, and the baffle 7 protrudes out of the first gear 61 along the circumferential outer wall of the axis of the first gear 61.

When the suspension assembly 4 passes through the spray booth 1 along with the traction chain 32, when the suspension assembly 4 passes through the area corresponding to the first rack 5, the suspension assembly 4 moves to enable the second gear 62 to move relative to the first rack 5, at the moment, the second gear 62 rotates through the meshing between the first rack 5 and the second gear 62, the second gear 62 rotates to enable the third gear 63 to synchronously rotate, after the third gear 63 rotates, the third gear 63 is meshed with the second gear 62 through the meshing between the third gear 63 and the second gear 62, and the third gear 63 is an incomplete gear, so that the third gear 63 drives the first gear 61 to rotate to belong to a continuous state, and the rotation of the hook portion 42 is in a rotation stop state. Because the rotation of the hook part 42 stops, the workpiece hung on the hook part 42 is easy to shake relative to the hook part 42 under the action of inertia, and the part which is abutted against the hook part 42 forms intermittent exposure in the shaking process, so that the abutted part of the workpiece and the hook part 42 can be sprayed.

Referring to fig. 1 and 2, a second rack 8 is fixed in the drying chamber 2, and the second rack 8 is configured to engage with the second gear 62. When the workpiece is driven by the traction chain 32 to pass through the drying chamber 2, the second gear 62 is rotated by the engagement of the second rack 8 and the second gear 62, so that the hook portion 42 is intermittently turned along the hinge axis to shake the workpiece. When the work piece rocks, can reduce the work piece on the one hand and contradict with couple portion 42 and be in the bonding that the stoving in-process because the paint vehicle leads to, on the other hand, rocks the in-process at the work piece, and the work piece forms relative motion for the air current in drying chamber 2 for the stoving effect is better.

Referring to fig. 2 and 3, the hook groove 421 is provided with the coming-off preventing portion 9 away from the hinge axis of the hook portion 42, the coming-off preventing portion 9 is hinged to the hook portion 42, and the hinge axis of the coming-off preventing portion 9 is arranged in the horizontal direction and perpendicular to the inclination direction of the hook portion 42. The hook portion 42 is provided with an elastic member 10, the elastic member 10 is a torsion spring, the anti-falling portion 9 protrudes out of the inner wall of the hook groove 421 under the action of the elastic force of the elastic member 10, and at this time, the anti-falling portion 9 is obliquely and upwardly arranged towards the direction away from the hinge axis of the anti-falling portion, and a gap for the workpiece to be installed is further left in the hook groove 421. The anti-falling part 9 is further fixed with a contact strip 11, and the contact strip 11 protrudes in an arc shape from the inner wall of the hook groove 421 away from the hinge axis of the hook part 42.

When the work piece moves to being close to the notch of hook groove 421, the strip of touch 11 is promoted by the work piece and is kept away from far away the upset of hook portion 42 hinge axis direction and make anticreep portion 9 overturn downwards, and the strip of touch 11 is used for conflicting the work piece and breaks away from hook groove 421 with the restriction work piece this moment, and this moment, the upset makes the notch of hook groove 421 diminish and makes the work piece can not directly break away from in hook groove 421 through anticreep portion 9 upset for the work piece is more stable in the hanging of hook groove 421.

The working principle of the embodiment is as follows:

when the automatic spraying production line is adopted, a workpiece is hung in the hook groove 421 of the suspension assembly 4, then the traction chain 32 is driven by the driving motor 33 to operate, so that the workpiece enters the spray chamber 1 firstly, and is sprayed and painted through the paint spraying unit, and the paint for spraying is generally water-based paint, so that the automatic spraying production line is harmless to a human body and does not pollute the environment. After the spraying of the workpiece is finished, the workpiece is driven by the traction chain 32 to move out of the spray chamber 1 and move into the drying chamber 2, the paint is dried and solidified by heating the drying chamber 2, then the workpiece is moved out of the drying chamber 2, and then the workpiece is taken down from the suspension assembly 4.
