Rotary drum and workpiece processing device

Abstract

The invention provides a rotary drum and a workpiece processing device. The rotary drum comprises a drum body and a conveying mechanism. The conveying mechanism comprises multiple material sliding parts. The material sliding parts are arrayed and arranged in the axial direction of the drum body and incline downwards in the direction from a feed port of the drum body to a discharge port. The workpiece processing device comprises the rotary drum mentioned above. The multiple material sliding parts are arranged, the first angle at which each material sliding part inclines downwards is set to be larger, and therefore in the process that workpieces slide on the material sliding parts, the component force, in the inclining direction of the material sliding parts, of the gravity of the workpiecesthemselves is increased and is larger than the viscous force, on the corresponding material sliding parts, of the workpieces, the workpieces can smoothly slide downwards under the effect of the gravity of the workpieces themselves, and it is avoided that the workpieces adhere to the material sliding parts; and meanwhile, by means of the multiple material sliding parts, the workpiece close to theposition of the feed port is transferred to the position below the material sliding part close to the position of the discharge port step by step, the phenomenon that the workpieces adhere to the material sliding parts is avoided while the bearing capacity is not decreased, and the discharge speed and the discharge completeness of the rotary drum are increased.

Description

technical field [0001] The invention relates to the technical field of electroplating, in particular to a drum and a workpiece processing device. Background technique [0002] Barrel plating and barrel electroplating are to place a certain number of small parts in a special barrel, and deposit various metal or alloy coatings on the surface of the parts in a way of indirect conduction in the barrel plating state, so as to achieve surface protection and decoration. An electroplating processing method for a functional purpose. [0003] For example, a drum disclosed in the Chinese patent document CN 208275859 U is provided with a feed port and a discharge port on both axial ends of the drum respectively, and the conveying port that is installed on the discharge port and fixed on the frame Mechanism, the conveying mechanism is arranged downwards from the feed port to the discharge port, the top of the conveying mechanism extends into the drum, and its bottom protrudes out of the...

Problems solved by technology

[0006] Or, when the radial height of the drum is not changed, the axial length of the drum is shortened so that most of the workpieces thrown by the drum fall on the top surface of the conveying mechanism, but the axial length of the drum is shortened , will reduce the inner cavity of the barrel body, the amount of workpieces that can be carried by the inner cavity is low, and the processing capacity of workpieces in the drum will be reduced, which will also affect the working efficiency of the drum

That is to say, it is difficult for the drum in the prior art to avoid the phenomenon that the workpiece sticks to the conveying mechanism without reducing the amount of the workpiece carried by the drum, so that the unloading speed of the drum is fast and the unloading is clean.
