The invention relates to the field of machinery manufacturing. Automatic painting equipment used for Christmas tree branches is provided and comprises a conveying structure, a material clamping structure, a glue dispensing and positioning structure, a drying device, a material loading frame and a plurality of conveying chains, wherein one of the chains is uniformly provided with a plurality of material separating fixtures, the material separating fixture at the front end of the chain is connected with the material clamping structure, the material separating fixture at the back end of the chain is connected with the drying device, and the material separating fixture in the middle section of the chain is connected with the glue dispensing and positioning structure. According to the automatic painting equipment used for the Christmas tree branches, the Christmas tree branches are fixed to all the structures through positioning magnets and V-shaped positioning grooves and are precisely fixed to the glue dispensing and positioning fixture from the material separating fixtures; when the Christmas tree branches are arranged upwards, the working position of a glue gun on one side is straightened by a cleaning and rotating air cylinder, and painting is conducted in the up-down direction through two sets of glue guns which are distributed uniformly, so that glue is effectively prevented from being leaked on leaves; accordingly, high-efficiency, all-round and full-automatic painting is achieved. The automatic painting equipment is simple and practical in structure, and it is ensured that the automatic painting equipment is operated effectively.
