Crawler shot blasting machine is a kind of equipment widely used in the surface treatment industry, mainly used for shot blasting of various metal products, in order to achieve the purpose of surface cleaning, strengthening and pretreatment before painting. This article will give a detailed introduction to the working principle of the crawler shot blasting machine, so that readers can better understand the working mode and characteristics of this equipment.
1. Overview of crawler shot blasting machine.
Crawler shot blasting machine is a continuous shot blasting equipment, which mainly throws the projectile to the metal surface through a high-speed rotating impeller to remove the oxide scale, rust and impurities on the surface, so that the metal surface becomes clean, rough and easy to paint. The crawler shot blasting machine has the characteristics of high efficiency, large processing capacity and continuous operation, so it has been widely used in automobile manufacturing, ship repair, construction industry and hardware products.
Second, the working principle of the crawler shot blasting machine.
The crawler shot blasting machine is mainly composed of the following parts: shot feeding system, shot blasting chamber, crawler transmission device and control system, etc. Here's a closer look at how each part works.
1.Pill feeding system.
The shot feeding system is one of the core parts of the crawler blast machine, which is mainly responsible for supplying projectiles to the impeller. There are many ways to supply projectiles, such as spiral conveying, air flow conveying, etc. In a crawler shot blasting machine, the projectile enters the high-speed rotating impeller through the shot supply tube, and under the action of centrifugal force, the projectile is thrown around, forming a uniform jet stream.
2.Shot blasting room.
The blast chamber is one of the core parts of the crawler blast machine, which is mainly responsible for throwing the projectile to the metal surface. The shot blasting chamber is usually welded with steel plates, and the interior is equipped with protective plates and observation windows. In the blast chamber, the metal products are fed through the conveyor belt and pass through the projectile ejection zone as the conveyor belt turns. At this time, the projectile hits the metal surface at high speed, generating a strong impact and friction, so that the oxide scale, rust and impurities on the metal surface are removed.
3.Crawler conveyor.
The crawler conveyor is one of the important components of the crawler shot blasting machine, which is mainly responsible for feeding the metal products into the shot blasting chamber and outputting the processed products. The crawler conveyor is usually composed of steel chain and rubber track, which has good wear resistance and anti-slip performance. Metal products are conveyed through a series of guide and tension wheels on the crawler conveyor to achieve stable and continuous conveyance. At the same time, the crawler conveyor is also equipped with automatic deviation correction and anti-deviation device to ensure the normal operation and service life of the conveyor belt.
4.Control system.
The control system is one of the key parts of the crawler shot blasting machine, which is mainly responsible for controlling the starting, running and stopping of the equipment. In the control system, control elements such as programmable logic controllers (PLCs) or industrial computers are usually used to realize the automatic control and monitoring of all parts of the equipment. At the same time, the control system is also equipped with safety protection devices, such as emergency stop buttons, safety door locks and protective covers, etc., to ensure the safety of equipment and operators.
Through the synergistic work of the above parts, the crawler shot blasting machine can efficiently complete the surface treatment of metal products. During the treatment process, the oxide scale, rust and impurities on the surface of the metal products are removed, and the surface becomes clean, rough and easy to coat. At the same time, the crawler shot blasting machine also has the characteristics of high efficiency, large processing capacity, continuous operation, etc., which can meet the needs of large-scale production.
