Abstract

The utility model discloses an unpowered corrective device of a color-painted wringer roll, relating to a corrective device in a steel production line and comprising an upper wringer roll, a lower wringer roll and a fixed bracket, wherein the upper wringer roll is connected with an air cylinder; the lower wringer roll is a fixed roll; the upper wringer roll and the lower wringer roll are fixed by wringer roll supporting arms at the two ends; the wringer roll supporting arms are respectively connected with the fixed bracket by movable swinging arms and movable shafts; and the working pressure of the wringer rolls can be increased by one time than that of the original wringer rolls, and the materials of the production line have no deviation phenomenon. The unpowered corrective device utilizes the forwarding power of a steel plate and the extruding pressure of the wringer rolls to the steel plate to carry out corrective fine tuning on the forwarding steel plate and does not need extra energy consumption.

Description

The unpowered deviation correcting device of color coating line squeeze roll

Technical field

The utility model relates to the deviation correcting device in the steel production line, refers in particular to the unpowered deviation correcting device of a kind of color coating line squeeze roll.

Background technology

In color coating line production technology, the vertical forward linear running of steel plate 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 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 control forward, by infrared ray the edges of plate is surveyed, and reaches the purpose of automatic deviation correction.On the 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 again after to residual water stain the extracting of surface of steel plate.Surface of steel plate water stain extracted fast to dry up be the needs of follow-up colour-coating technology, to dry up be another important step on the color coating line so extract.Squeezing apparatus is made up of last squeeze roll and bootom couch squeeze roll, and last bootom couch squeeze roll is directly installed on the fixed support, and steel plate moves between upper and lower squeeze roll, and last squeeze roll presses down with the cylinder guiding, and bootom couch squeeze roll is a fixed roll.Because squeeze roll has pressure at right angle to surface of steel plate,, can cause water squeezing not thorough if pressure is little; If pressure is excessive, might wander off owing to the residual water stain inhomogeneous steel plate both sides unbalance stress that causes, influence the vertical forward linear running of steel plate, so the conventional pressure that adopts is 0.3Mpa.Though have EPC and CPC system for automatically correcting to control automatically,, just can produce all kinds of quality problems, even have influence on the normal operation of whole production line if the laterally undue skew of steel plate causes the infrared ray of deviation-rectifying system to fail correctly to gather signal.And this squeeze roll can only tentatively be extracted the water stain of surface of steel plate, but can't guide vertical linear running of steel plate well.

Summary of the invention

The utility model 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 the unpowered deviation correcting device of color coating line squeeze roll of horizontal fine tune again, 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 unpowered correction synchronously.

The utility model can be realized like this: the unpowered deviation correcting device of color coating line squeeze roll, comprise squeeze roll, bootom couch squeeze roll, fixed support, last squeeze roll connects cylinder, bootom couch squeeze roll is a 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 last squeeze roll increases, cause moving the surface of steel plate discontinuity, steel plate can be to the big side lateral shift of pressure, because it is last, following 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 utility model 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 °.

The squeeze roll of going up of the present utility model is connected with cylinder, and the pressure in the cylinder can be regulated by pressure valve, in order to obtain better to extract effect, and the moderate pressure increasing, output pressure that can control cylinder is 0.4Mpa-0.6Mpa.So just can go up the pressure size of squeeze roll according to how many adjustings of water on the steel plate to steel plate.

The junction of bootom couch squeeze roll of the present utility model and squeeze roll support arm is provided with screw mandrel, and screw mandrel can play a part to finely tune bootom couch squeeze roll up and down, helps regulating and control the upward distance between bootom couch squeeze roll, to obtain better water squeezing effect.

Effect advantage of the present utility model 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 does not have deviation phenomenon, and after the squeeze roll water squeezing the dry exclusion of material surface, for later process provides good basis, the pin hole phenomenon of product surface is eliminated substantially, 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, the unpowered deviation correcting device of color coating line squeeze roll, comprise squeeze roll 1, bootom couch squeeze roll 2, fixed support 3, last squeeze roll 1 connects cylinder 4, bootom couch squeeze roll 2 is a 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.

Embodiment 2, reference example 1, and bootom couch squeeze roll 2 is provided with screw mandrel 8 in addition with the junction of squeeze roll support arm 5, and the amplitude of fluctuation of the activity swing arm 6 that links to each other with fixed support 3 with squeeze roll support arm 5 is designed to ± and 30 °.

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 utility model, the operating pressure of top squeeze roll can be designed at 0.4Mpa-0.6Mpa, the pressure size of squeeze roll to steel plate gone up in how many adjustings according to water on the steel plate, under this operating pressure, can reach thorough steel plate and extract the water stain purpose in surface.
