Abstract

The utility model discloses a horizontal color coating passivation device, which comprises two groups of upper and lower drying rolls. Steel strips (4) pass through the upper and lower drying rolls (1 and 2) for color coating passivation. The horizontal color coating passivation device is characterized in that a movable steel roller (3) is arranged on the circumference of each of the upper and lower drying rolls (1 and 2). On the basis of the conventional passivation device, two 20cm steel strips are added for transmission, so that a steel plate can be ensured to be lifted at any time during coating, a passivation solution cannot be adhered to a plate surface, and the problem of influence of passivation on the quality of a product is solved. The replacement of the rollers is reduced, and the rollers are conveniently cleaned when the device is stopped. The horizontal color coating passivation device is less in equipment investment, has an improvement effect, and is particularly applicable to band steel galvanizing and color coating machine sets.

Description

Horizontal color coating passivation device

Technical field

The utility model relates in the thin plate colour-coating technology improvement to equipment, especially about a kind of device that is used for horizontal color coating passivation.

Background technology

Color painted steel strip is meant the steel plate that on substrate, has organic coating, and its its plate commonly used is cold-rolled substrate, hot dip galvanizing substrate.Color painted steel strip has good corrosion resistance, bright in luster, appearance looks elegant, convenient, high, the low cost and other advantages of intensity of machine-shaping, is widely used in building household electrical appliances and communications and indoor decoration etc.But the color product made from steel quality of China also is in low side.The galvanizing colored steel is when color coating passivation, substrate application organic coating; In vertical direction; The upper and lower surfaces of band steel is equipped with one respectively and goes up squeeze roll and following squeeze roll; The operation of following squeeze roll and steel band keeps tangent and arranges perpendicular to band steel center line horizontal direction, and the operation of last squeeze roll and steel band also keeps tangent and perpendicular to being with steel center line horizontal direction layout, and the person all has organic coating (liquid) and contacts and accomplish its coating with steel band between the upper and lower squeeze roll.But because the gap between the upper and lower squeeze roll is changeless after confirming; When the joint that runs into steel band through here or substrate unevenness deviation when big; Upper and lower squeeze roll can not lift; Joint scratches rubber roll easily, cause passivation layer coarse inhomogeneous, cause in the color coating process and to be prone to produce paint film phenomenons such as coating aberration, current mark, thereby influence the quality of product.

Summary of the invention

To above deficiency; The purpose of the utility model is to provide a kind of horizontal color coating passivation device; Be between upper and lower squeeze roll, respectively to increase a mobilizable steel rider; When making the color coating passivation, organic coating is sprayed on upper and lower squeeze roll earlier, realizes the coating of steel band again through the engagement of upper and lower squeeze roll with steel rider.

The technical scheme of the utility model realizes in the following manner: horizontal color coating passivation device; Comprise two groups of upper and lower squeeze rolls; Steel band through realizing the color coating passivation, is characterized in that from upper and lower squeeze roll: the steel rider that respectively is provided with an activity on the circumference of described upward squeeze roll and following squeeze roll.

The diameter of described steel band is 100mm, with the angle of the tangential direction of squeeze roll be 45o.

The below of described upper and lower squeeze roll is provided with oil drain pan, and the below of oil drain pan is provided with flowline.

The utility model structure on original passivation device basic, adds two each 100CM steel rider band transmissions.Guarantee when application, can lift at any time, and the plate face can not be stained with passivating solution, can not cause the problem that influences product quality because of passivation yet.Reduce the replacing of roller, and when shutting down, be convenient to clean.And avoided up and down squeeze roll that the working face of squeeze roll has been protected in the scuffing of band steel simultaneously, and improved squeeze roll service life, the squeeze roll function is not fully exerted, extract effect and also improve thereupon.The utility model used device is few, improvement is effective, is particularly suitable for strip steel Zn-plating and color coating unit and uses.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Know that by Fig. 1 color coating passivation device comprises two groups of upper and lower squeeze rolls, steel band 4 from last squeeze roll 1, down the squeeze roll 2 through carrying out the color coating passivation, in the steel band porch, respectively be provided with a mobilizable steel rider 3 on the circumference of last squeeze roll 1 and following squeeze roll 2.The diameter of steel band 4 is 100mm, with the tangential direction angle of squeeze roll be 45o.Below upper and lower squeeze roll, be provided with oil drain pan 5, there is flowline 6 below of oil drain pan 5.

During work; Steel band 4 is gone up squeeze roll 1, the following squeeze roll 2 from the porch entering of color coating passivation device, upper and lower squeeze roll rotation this moment, and the steel rider 3 that rotates with last squeeze roll 1 tangential direction brings squeeze roll 1 with passivating solution; The steel rider 3 that rotates with following squeeze roll 2 tangential directions brings down squeeze roll 2 with passivating solution; Upper and lower squeeze roll brings passivating solution the above and below of steel band 4 again, and the coat that obtains of steel band 4 is uniformly like this, and that zinc coat has been avoided is coarse, hang zinc and in the color coating process, be prone to produce the paint film phenomenons such as pin hole, bubble, shrinkage cavity, aberration, current mark of filming; Squeeze roll 1 can lift automatically on the joint; Be not easy to scratch rubber roll, the unnecessary passivating solution of being taken out of by steel rider 3 is by collecting through the oil drain pan 5 that is arranged on passivation device below, and flowline 6 outputs are arranged.

Claims (3)

1. horizontal color coating passivation device; Comprise two groups of upper and lower squeeze rolls; Steel band (4) through realizing the color coating passivation, is characterized in that from last squeeze roll (1), following squeeze roll (2): the steel rider (3) that respectively is provided with an activity on the circumference of described upward squeeze roll (1) and following squeeze roll (2).

2. horizontal color coating passivation device according to claim 1, it is characterized in that: the diameter of described steel band (4) is 100mm, with the angle of the tangential direction of squeeze roll be 45o.

3. horizontal color coating passivation device according to claim 1, it is characterized in that: the below of described upper and lower squeeze roll is provided with oil drain pan (5), and the below of oil drain pan (5) is provided with flowline (6).
