Automatic PLC control system 1.5m steel plate pretreatment line
Detailed description:

Fully automatic PLC control system 1.5 meters pass-through steel plate pretreatment line Steel plate pretreatment line Uses:
The steel plate pretreatment line process refers to the processing process of surface blasting and rust removal and coating with a protective primer before the steel is processed (that is, the state of raw materials). The pretreatment of steel can improve the corrosion resistance of mechanical products and metal components, improve the fatigue resistance of steel plates, and extend its service life. At the same time, it can also optimize the state of the steel surface manufacturing process, which is conducive to CNC cutting and blanking. In addition, because the shape of steel before processing is relatively regular, which is conducive to mechanical rust removal and automatic painting, the use of steel pretreatment can greatly improve the efficiency of cleaning work, reduce the labor intensity of cleaning work and environmental pollution. Because of this, the steel plate pretreatment process has not only been popularized and applied in developed countries, but has also attracted increasing attention in many industries in China. Many companies have put the steel pretreatment process on the agenda of corporate technological transformation.
In order to comprehensively improve the usability and reliability of the product and meet the needs of users as much as possible, our company adopts the following key technologies and guarantee measures in the design of the steel plate profile pretreatment pipeline:
ˉ Workpiece conveying system The whole set of workpiece conveying system has stepless speed regulation by frequency conversion, which can not only run synchronously, but also each department can act independently. The roller of the shot blasting chamber is equipped with a special material wear-resistant jacket. The shot blaster is optimized and designed by computer simulation. The shots are fully utilized and the structure is compact and perfect.
Shotgun cleaning
Use primary cleaning + secondary air blowing
1. First-level cleaning: high-strength nylon roller brush + pill receiving spiral
2. Secondary air blowing: high pressure fan blows the shot twice in the shot blasting room (ash)
循环 Pill recycling purification
The most complete separated projectile full curtain type air separation separator is used. The projectile circulation system is set with an automatic alarm function for failure. If any failure occurs, the equipment automatically detects and protects.
ˉShot blasting dust removal system
The user can choose to use a bag filter. The dust emission of the bag filter can reach 50mg / m3.
The following is a real shot of the installation and commissioning of our steel plate pretreatment line:

The composition and working principle of the 1.5-meter pass-through steel plate pretreatment line is mainly composed of a roller conveyor system, a shot blasting cleaning machine, a shot blasting dust removal system, and an electronic control system. Its working principle is: it is sent to the closed shot blasting room by the conveying roller table, and the high-speed rotating impeller of the shot blaster is used to accelerate the wire cutting shot (shot) to the workpiece surface, and the workpiece surface is impacted and scraped to remove the workpiece. Rust and dirt on the surface, and then use the sweeping, rolling brush, shot-receiving spiral and high-pressure blow pipe to clean up the accumulated pellets and floating dust on the surface of the workpiece, and then send it out of the roller, so that the steel can achieve the purpose of rust removal and rust prevention.

Product quality assurance measures
1. The steel plates and profiles required for the products are all purchased from famous brand manufacturers.
2. All steel plates, profiles or components that make up the equipment are uniformly derusted and sprayed with a maintenance primer.
3. The supporting standard parts should be purchased from famous brand manufacturers as much as possible, such as bearings, motors, reducers, etc.
4. Load test of key components shot blasting plant, dry running test of various motion institutions.
5. Design and quality inspection personnel set up a special quality supervision team to supervise the implementation of the above steps to ensure product quality.
After-sales service guarantee measures
1. "Three Guarantees" is implemented for product quality, and the "Three Guarantees" period is one year;
2. During the three-guarantee period, repairs and replacements of electrical control and mechanical parts failures and damaged parts due to normal use (except man-made and wearing parts);
3. The after-sales service implements a "24-hour" response, that is, the user contacts our company's after-sales service office (phone: 0515-83752966) to ensure that the phone is resolved within 24 hours or someone is sent out.

Precautions during normal work and maintenance In order to ensure the safety of equipment and personnel, the following matters must be noted during normal work and maintenance:
(1). It is not allowed to open the blast room maintenance door while the equipment is running. Before maintenance, the power of relevant equipment in the shot blasting room must be turned off before personnel can enter.
(2). Before repairing the field equipment and electrical components, turn off the corresponding power switches (knife switch and automatic air switch), and notify the operator of the main console. The sign "Now being overhauled, no electricity is allowed".
(3). All protection devices, such as chains and V-belts, can only be removed during maintenance, and must be reset immediately after the work is completed.
(4). Do not cross from above the roller table while the roller table is moving.
(5). In the shot blasting area, the floor must be kept absolutely clean, and no shots should be present to avoid slipping and falling.
(6). The operator of the main control room must notify the on-site personnel to make preparations before each startup.
(7). During maintenance, be careful not to drop or forget objects such as tools or parts in the operating mechanism, so as to avoid accidents after the equipment starts.
(8). The main control room and on-site operators must concentrate their energy and work carefully, and must not leave the post without permission.
(9). During production, if an abnormal situation is found, you can press the emergency stop button to stop the operation of the roller table and close the fan valve.
