Description

Technical Field

[0001] This utility model relates to the field of coating exterior parts technology, specifically to a coating exterior parts loading and unloading trolley. Background Technology

[0002] Painted exterior parts refer to decorative and functional composite structural parts installed on the outside of mechanical equipment. They are mainly used for exterior decoration and protection in the fields of automobiles and construction machinery. Painted exterior parts require a painted exterior parts loading and unloading trolley during loading and unloading.

[0003] In response, Chinese patent application number CN220130173U discloses a loading and unloading structure for a transfer trolley, including a support assembly. Each of the four corners of the lower end face of the support assembly is equipped with a guide caster. The inner end face of the support assembly is symmetrically and rotatably engaged with a synchronous pulley. The two sets of synchronous pulleys are connected by an arc-toothed synchronous belt. This invention, by setting up an unloading assembly, allows a servo motor to synchronously drive two sets of lead screws to rotate during automated unloading of goods. This enables the two sets of lead screws to synchronously drive the unloading assembly to automatically push the goods inside the support assembly. Simultaneously, the unloading assembly located at the front can be separated from the support assembly, thereby improving the efficiency and automation of unloading goods.

[0004] However, existing paint exterior parts loading and unloading trolleys require loading, unloading, and transferring paint exterior parts during use, but the existing equipment cannot lift the transfer platform as needed, which increases the operator's workload and thus increases labor costs.

[0005] Therefore, in order to solve the above problems, a painting exterior parts loading and unloading trolley is proposed. Utility Model Content
