Abstract
The invention discloses a color-coating line wringing roller unpowered deviation correction device, and relates to the deviation correction device in a steel production line. The device comprises an upper wringing roller, a lower wringing roller and a fixing support. The upper wringing roller is connected with cylinders. The lower wringing roller is a fixed roller. The upper wringing roller and the lower wringing roller are fixed through wringing roller support arms arranged on both ends of the upper wringing roller and the lower wringing roller. The two wringing roller support arms are connected with the fixing support respectively through movable swing arms and movable shafts. According to the present invention, working pressure of the wringing rollers is double than the original working pressure; the deviation phenomenon of the production material does not exist; the device adopts the forward power of the steel plate and the pressure generated through squeezing the steel plate by the wringing rollers to carry out slight adjustment of the deviation correction for the forward steel plate, such that additional energy consumption is not required.
Description
Technical field
The present invention relates to the deviation correcting device in the steel production line, refer in particular to a kind of Unpowered corrective device of color-painted wringer roll.
Background technology
In the color-coating line production technology, steel plate forward vertical linear running is an important link.The straight line of steel plate moves forward and the aridity on surface, and is closely related with the quality of the key element such as posting fully of the coating of priming paint, finish paint, PVC film, PET and product. affect the operating efficiency of production line and the yield rate of colored steel.At present, it is to adopt edge aligning system (EPC) and center support system (CPC) automatic deviation correction that the straight line of steel plate moves forward control, by infrared ray the edges of plate is surveyed, and reaches the purpose of automatic deviation correction.On color-coating line, the antirust processing of surface of steel plate is through after cleaning, and needs to pass through hot blast drying through squeeze roll after to residual water stain the extracting of surface of steel plate again.It is the needs of follow-up colour-coating technology that the water stain Quick squeezing of surface of steel plate is dried up, and to dry up be another important step on the color coating line so extract.Squeezing apparatus is comprised of upper squeeze roll and bootom couch squeeze roll, and upper bootom couch squeeze roll is directly installed on the fixed support, and steel plate moves between upper and lower squeeze roll, and upper squeeze roll presses down with the cylinder guiding, and bootom couch squeeze roll is fixed roll.Because squeeze roll has pressure at right angle to surface of steel plate, if pressure is little, can cause water squeezing not thorough; If pressure is excessive, might wander off owing to the residual water stain inhomogeneous steel plate both sides unbalance stress that causes, affect forward vertical linear running of steel plate, so the conventional pressure that adopts is 0.3Mpa.Although have EPC and CPC system for automatically correcting automatically to control, if steel plate laterally undue skew cause the infrared ray of deviation-rectifying system to fail correctly collection signal, just can produce all kinds of quality problems, even have influence on the normal operation of whole production line.And this squeeze roll can only tentatively be extracted the water stain of surface of steel plate, but can't guide well vertical linear running of steel plate.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, provide a kind of utilize steel plate forward power and squeeze roll to the pressure of steel plate, make steel plate in by water squeezing, can make again the Unpowered corrective device of color-painted wringer roll of horizontal fine tune, for preliminary pre-adjustment effect is played in follow-up accurate correction adjustment, the work that guarantees deviation-rectifying system is more timely, accurate, reaches not only to extract the purpose that the surface is water stain but also carry out synchronously unpowered correction.
The present invention can realize like this: Unpowered corrective device of color-painted wringer roll, comprise squeeze roll, bootom couch squeeze roll, fixed support, upper squeeze roll connects cylinder, bootom couch squeeze roll is fixed roll, it is characterized in that upper and lower squeeze roll fixed by the squeeze roll support arm at two ends, described two squeeze roll support arms are linked to each other with fixed support by activity swing arm and movable axis respectively.During work, because the operating pressure of upper squeeze roll increases, cause moving the surface of steel plate discontinuity, steel plate can be to the large side lateral shift of pressure, because upper, lower damping roller is fixed on the squeeze roll support arm, the squeeze roll support arm links to each other with fixed support with movable axis by the activity swing arm, the activity swing arm begins to play a role, laterally carry out small size translation by the activity swing arm, the present invention is designed to the amplitude of fluctuation of the activity swing arm that the squeeze roll support arm links to each other with fixed support ± and 30 °, general just can eliminate the biasing force of steel plate self, the linear running direction of maintenance steel plate by the swing in ± 30 °.
Upper squeeze roll of the present invention is connected with cylinder, and the pressure in the cylinder can be regulated by pressure valve, and in order to obtain better to extract effect, moderate pressure strengthens, and output pressure that can control cylinder is 0.4Mpa-0.6Mpa.So just can be big or small to the pressure of steel plate according to the upper squeeze roll of how many adjustings of water on the steel plate.
The junction of bootom couch squeeze roll of the present invention and squeeze roll support arm is provided with screw mandrel, and screw mandrel can play a part to finely tune up and down bootom couch squeeze roll, is conducive to regulate and control the distance between upper bootom couch squeeze roll, to obtain better water squeezing effect.
Effect advantage of the present invention is: the operating pressure of squeeze roll is comparable to nearly double originally, can bring up to 0.6Mpa by 0.3Mpa, the production line material is without deviation phenomenon, and after the squeeze roll water squeezing the dry exclusion of material surface, for later process provides good basis, the pin-hole phenomena elimination of product surface has improved the qualification rate of material.In addition, this device is to utilize the pressure of power that steel plate moves ahead and squeeze roll pressing steel plate to come the steel plate that moves ahead is done the fine setting of correction, need not additional energy source consumption.

The specific embodiment
Embodiment 1, Unpowered corrective device of color-painted wringer roll, comprise squeeze roll 1, bootom couch squeeze roll 2, fixed support 3, upper squeeze roll 1 connects cylinder 4, bootom couch squeeze roll 2 is fixed roll, upper and lower squeeze roll is fixing by the squeeze roll support arm 5 at two ends, and described two squeeze roll support arms 5 are linked to each other with fixed support 3 by activity swing arm 6 and movable axis 7 respectively.
The antirust processing of surface of steel plate is after removing, enter the squeeze roll working link, owing to be provided with deviation correcting device of the present invention, the operating pressure of top squeeze roll can be designed at 0.4Mpa-0.6Mpa, the upper squeeze roll of how many adjustings according to water on the steel plate is big or small to the pressure of steel plate, under this operating pressure, can reach thorough steel plate and extract the water stain purpose in surface.
