Example Embodiment

[0042] Example one

[0043] The technical scheme of the paint stripping equipment of the present invention includes a circular track 1, a self-propelled car 3, a liquid nitrogen tank 2, a metal particle impact bin 4, and a control system. The circular track 1 is horizontally suspended in the liquid nitrogen tank 2 and the metal particle impacts Right above the warehouse 4, the liquid nitrogen tank 2 contains liquid nitrogen. The self-propelled trolley 3 is arranged on the circular track 1 and can move along the circular track 1. The self-propelled trolley 3 is provided with a clamping mechanism for clamping metal hangers, A hoisting mechanism for controlling the up and down movement of the clamping mechanism and a driving mechanism for driving the metal hanger to rotate along its own longitudinal center axis;

[0044] The metal particle impact bin 4 includes a bin body and a shot blasting mechanism 16 capable of ejecting projectiles into the bin body. The top of the bin body is pro...

Example Embodiment

[0052] Example two

[0053] On the basis of the first embodiment, the shot blasting mechanism 16 can also be set up in another way: an opening is opened on one side wall of the large particle impact chamber 5, medium particle impact chamber 6, and small particle impact chamber 7, each A group of multi-degree-of-freedom manipulators 21 are provided at each opening, and a shot blasting mechanism 16 is provided at the cantilever end of the multi-degree-of-freedom manipulator 21, and extends into the metal particle impact bin 4 from the opening.

[0054] At the same time, protective clothing is also needed at the opening, and the multi-degree-of-freedom manipulator 21 is covered inside the protective clothing, and the protective clothing is connected to the opening. To reflect the structure of the multi-degree-of-freedom manipulator, the protective clothing is omitted in the drawings.

[0055] The multi-degree-of-freedom manipulator 21 in this embodiment can perform multi-angle shot blas...

Abstract

The invention provides a paint removing method and paint removing equipment for a surface of a metal hanging rack. Liquid-nitrogen soaking and metal particles are utilized to perform paint removal treatment on a paint resin coating on the surface of the metal hanging rack, so that the problem that paint removing effect is poor and environmental pollution is caused due to the fact that the metal hanging rack adopts an existing paint removing method is solved. The paint removing method comprises a liquid nitrogen soaking step and a multi-stage variable-frequency particle colliding step; the paint removing equipment comprises a ring-shaped rail, a self-propelling car, a liquid nitrogen slot, a metal particle impact bin and a control system; the ring-shaped rail is horizontally suspended above the liquid nitrogen slot and the metal particle impact bin; liquid nitrogen is contained in the liquid nitrogen slot; the self-propelling car is arranged on the ring-shaped rail, and can move along the ring-shaped rail; and the self-propelling car is equipped with a clamping mechanism used for clamping the metal hanging rack, a hoisting mechanism used for controlling the clamping mechanism to move up and down, and a drive mechanism used for driving the metal hanging rack to rotate along the longitudinal central shaft thereof.

Description

Technical field [0001] The invention relates to the field of paint removal on metal surfaces, in particular to a method and equipment for removing paint on the surface of a metal hanger. Background technique [0002] With the large-scale development of the industry, in the manufacturing fields of home appliances, automobiles, and electronic products, in order to ensure the quality standards and the aesthetics of the viewing parts, the coating process is more and more widely used. In the production process, a large number of hangers need to be reused after stripping paint. In the past, the paint and resin on the surface of coating racks were cleaned by direct incineration or chemical dissolution and swelling; however, the harmful gases, toxic residues, or toxic waste liquid discharged by this rough treatment are harmful to the atmosphere, water, and soil. Caused serious pollution. Looking at the smog raging across the country, we can deeply perceive how great the damage caused b...
