Description
Technical Field
The utility model belongs to the metallurgical equipment field specifically is a color painted production line roller coat machine's improvement structure.
Background
The production line for producing the color-coated steel plate is called a color-coating production line, the raw material is a galvanized steel plate and an aluminum-zinc plated steel plate, after the raw material is cleaned and dried, paint with required color is coated on the raw material through a roller coater, then the raw material enters a drying furnace for drying, and finally the raw material is rolled to finish processing. The most important equipment in the color coating production line is a roller coater, and the most important links are to control the thickness and quality of a paint film of a color coated plate and the cost of the whole production line. At present, a roller coater of a color coating production line consists of three rollers, namely a supporting roller, a coating roller and a strip roller, the thickness of a paint film is controlled by adjusting the strip roller and the coating roller, and the conditions of foaming, color difference and the like of paint coated on a steel plate are obtained, and the roller coater belongs to a relatively mature equipment application mode. However, in the actual field use process, the adjustment condition of the finished color-coated sheet from the drying oven is known only by the experience and the strength of the adjustment belt roller and the adjustment coating roller, so that the control of the product quality is greatly delayed, and the color-coated steel sheet needs to be adjusted again and repeatedly for testing every time when changing one color and one paint film thickness, thereby causing great economic loss of the color-coated steel sheet. Moreover, the thickness of a paint film on the whole plate surface is not well controlled, particularly, when a coating roller passes through a plate belt joint in production, the coating roller is frequently separated or is attached to a plate belt which is greatly supported, because the pressure between the roller and the coating roller is not uniformly adjusted or the pressure is too high, the roller head of the strip roller is frequently broken, faults are generated to cause stop, the over-drying of a color coating plate on a production line, the insufficient number of meters and the like are caused, the economic loss is high, the equipment cannot normally operate, and the production cost is too high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the shortcomings of the prior art, and provides an improved structure of a color coating production line roller coater which has simple structure, reasonable design and convenient wearing and taking off.
The utility model provides a its technical problem take following technical scheme to realize:
the utility model provides a color coating production line roller coat machine's improvement structure which characterized in that: the material-carrying roller screw synchronous rotation device comprises a shell, ejector rods, a turbine speed reducer, a material-carrying roller screw, a fixed base and a pressure sensor, wherein a plurality of ejector rods horizontally and transversely arranged penetrate through the shell; ball bearings are arranged between the radial contact surfaces of the ejector rod and the casing, end covers and fixed bases are fixed on the casing at the two axial ends of the ball bearings respectively, and pressure sensors are arranged on the ejector rod on the end surface of each fixed base.
And a hand wheel is arranged on a bracket of the turbine speed reducer, and the hand wheel is rotated to adjust a screw rod of the material-carrying roller, so that the pressure between the material-carrying roller and the coating roller is adjusted.
Moreover, the pressure sensor is an oblate sensor, and the sensor is connected with the display through a circuit, so that the pressure borne by the current material carrying roller can be observed in real time.
The utility model has the advantages that:
1. the utility model discloses safe and reliable in actual production process, the operation is stable, and the institutional advancement of this scheme is though not big, but can effectually prevent because the uneven or too big frequent leading to the fact of pressure takes material roller spindle nose fracture between roller and the roller, has reduced the down time of equipment, has reduced the quantity of spare parts, has promoted the rate of opening of equipment.
2. The utility model discloses can not have the color-coated sheet of individual specification for production to have recorded the reliable data of important process standard, provide effectual operation foundation for production operating personnel, the control color-coated sheet that can be timely takes lacquer film thickness and quality, has avoided a large amount of losses and the waste of slab band, has reduced very big economic loss for the company, has reduced manufacturing cost.
