Abstract
The utility model discloses an adjusting mechanism for reverse roll coating, which comprises a coating roll and a wall plate for mounting the coating roll, and further comprises a servomotor, a coupler, a spline shaft and a differential screw, wherein the servomotor is connected with the coupler; the lower end of the coupler is connected with the spline shaft; the spline shaft is matched with the differential screw; the differential screw is in threaded connection with a fixing nut; an internally threaded hole is formed in the lower part of the differential screw, and is in threaded connection with a sliding screw; a spring is arranged between the top of the sliding screw and the lower end of the spline shaft; the lower end of the sliding screw is connected with a sliding block; guide rails, through which the sliding block moves up and down, are arranged on two sides of the sliding block; and the servomotor drives the spline shaft to rotate through the coupler, so that the differential screw can not only rotate in the fixing nut, but also translate axially along the spline shaft, and the sliding block obtains a slight feeding amount according to the differential screw principle. The sliding block drives a metering roll and a backup roll to move, so as to adjust the coating clearance.
Description
Technical field
The utility model relates to a kind of reverse roll coating governor motion.
Background technology
Coating is that one or more layers material with specific function is attached on the substrate surface, to improve substrate surface function or protection base material, strengthens the value of base material.The method of coating has multiple, and reverse roll coating is higher a kind of of precision.In the reverse roll coating system, the setting of coating clearance is very important.For guaranteeing to set up the accuracy of roller gap size, a kind of differential screw control method is proposed.
The utility model content
The utility model purpose is to provide a kind of reverse roll coating governor motion for the defective that prior art exists.
The utility model for achieving the above object, adopt following technical scheme: a kind of reverse roll coating governor motion, the wallboard that comprises applicator roll and installation applicator roll, also comprise servomotor, shaft coupling, splined shaft, differential screw arbor, described servomotor links to each other with shaft coupling, the shaft coupling lower end connects splined shaft, described splined shaft and differential screw arbor match, described differential screw arbor is threaded with hold-down nut, described differential screw arbor bottom is provided with internal thread hole, described internal thread hole is threaded with sliding screw, also is provided with spring between the top of described sliding screw and the splined shaft lower end; Described sliding screw lower end links to each other with slide block, and described slide block both sides are provided with the guide rail that it is moved up and down.
Further, described guide rail one side is provided with displacement transducer.
The beneficial effects of the utility model: servomotor drives the splined shaft rotation by shaft coupling, realizes that differential screw arbor both can rotate in hold-down nut, again can be along the splined shaft axial translation, according to the differential screw principle so that slide block obtains the small amount of feeding.Slide block drives metering roll and back flow roll motion, thereby reaches the purpose of adjusting coating clearance.Linear displacement transducer is sent the actual displacement signal that detects back to processor and is processed, and adjusts the driving of motor, makes the adjustment at two ends synchronous, obtains accurately adjustment amount.
Description of drawings
Fig. 1 structural representation of the present utility model.
The specific embodiment
Fig. 1 is a kind of reverse roll coating governor motion, the wallboard 10 that comprises applicator roll 13 and installation applicator roll 13, also comprise servomotor 1, shaft coupling 7, splined shaft 8, differential screw arbor 3, described servomotor 1 links to each other with shaft coupling 7, shaft coupling 7 lower ends connect splined shaft 8, described splined shaft 8 matches with differential screw arbor 3, described differential screw arbor 3 is threaded with hold-down nut 9, described differential screw arbor 3 bottoms are provided with internal thread hole, described internal thread hole is threaded with sliding screw 4, also is provided with spring 2 between the top of described sliding screw 4 and splined shaft 8 lower ends; Described sliding screw 4 lower ends link to each other with slide block 12, and described slide block 12 both sides are provided with and make its guide rail that moves up and down 6; Wherein, described guide rail 6 one sides are provided with displacement transducer 5.Displacement transducer 5 is sent the actual displacement signal that detects back to processor and is processed, and adjusts the driving of motor, makes the adjustment at two ends synchronous, obtains accurately adjustment amount.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
