The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further; Referring to Fig. 1 and Fig. 2; The adhesive tape extrusion press is Webbing take-up device at the uniform velocity, and the upper fixed of lathe bed 16 is equipped with main shaft casing 2, lathe bed 16 1 sides be separately installed with bearing A12 and bearing B15 up and down; Bearing A12 upper fixed is equipped with strut member 9, and adhesive tape 22 is located on the strut member 9; Bearing B15 upper fixed is equipped with variable-frequency motor 13, and variable-frequency motor 13 is equipped with sprocket wheel B14, and reducing motor 17 is connected with lathe bed 16 through sprocket wheel degree of tightness regulating part 18; It is characterized in that reducing motor 17 is equipped with sprocket wheel C19 and is connected with the sprocket wheel A1 of main shaft casing 2 through roller chain 20, sprocket wheel A1 is installed on an end of main shaft 3; The other end of main shaft 3 is equipped with bearing 4, and is connected with an end of diameter progressive screw 5 through bearing pin, and diameter progressive screw 5 is provided with screw rod cavity 6; The other end of diameter progressive screw 5 is provided with glue discharging mouth 8, and glue discharging mouth 8 is connected as a single entity through nut 7 and screw rod cavity 6, and bearing A12 below is installed with velometer 11; Velometer 11 is equipped with rotary encoder 21; Adhesive tape substrate 23 places in the water tank, and passes rotary encoder 21 and connect glue discharging mouths 8, and sprocket wheel B14 is connected through roller chain 20 with sprocket wheel on the winding part 10.
Embodiment:The adhesive tape extrusion press is Webbing take-up device at the uniform velocity; Reducing motor 17 is through drive main shaft 3 rotations under the support of main shaft casing 2 and bearing 4 of sprocket wheel C19, sprocket wheel A1 and roller chain 20; Main shaft 3 drives diameter progressive screw 5 through bearing pin and moves along screw rod cavity 6; Glue is evenly spread upon through glue discharging mouth 8 on the adhesive tape 22 of strut member 9 supports, accomplish the plastic squeeze action.Glue discharging mouth 8 is connected with screw rod cavity 6 through nut 7, and glue discharging mouth 8 is according to technological requirement design different specifications.Adhesive tape substrate 23 places in the water tank, and passes rotary encoder 21 and connect glue discharging mouths 8, and sprocket wheel B14 is connected through roller chain 20 with sprocket wheel on the winding part 10.Adhesive tape 22 is through velometer 11, and rotary encoder 21 records the tape transport linear velocity, feeds back to the rotating speed of variable-frequency motor 13 frequency conversion outputs and linear velocity coupling, makes the tape transport linear velocity not change because of the winding diameter variation.Variable-frequency motor 13 is through sprocket wheel 14; Single bush roller chaiin; Sprocket wheel on the winding part 10 and a pair of gear; The take-up spool that the adhesive tape that has been coated with glued membrane 22 at the uniform velocity is wrapped in winding part 10 puts, and the winding axle sleeve is connected with the take-up spool spline, and refrigerator for cold is taken off and put into to the winding axle sleeve (being contained on the winding part 10) that has twined adhesive tape 22 easily on the slave unit.During use glued membrane is taken off from adhesive tape 22 gently.The degree of tightness of bush roller chaiin can be regulated through sprocket wheel degree of tightness regulating part 18.Variable-frequency motor 13 is connected with lathe bed 16 through bearing 15; Winding part 10, velometer 11, strut member 9 are connected with lathe bed 16 through bearing 12; Main shaft casing 2 is connected with lathe bed 16 through bolt; The support assemblies that main shaft 3 passes through bearing 4 is on main shaft casing 2, and screw rod cavity 6 is connected (screw rod cavity 6 will conveniently be installed and removed) through locating dowel pin, bolt and main shaft casing 2, and glue discharging mouth 8 is connected as a single entity through nut 7 and screw rod cavity 6.
In sum, the adhesive tape extrusion press of the utility model at the uniform velocity Webbing take-up device mainly by driving system, plastic squeeze head, at the uniform velocity parts such as Webbing take-up device are formed.The plastic squeeze head is made up of sprocket wheel A1, main shaft casing 2, main shaft 3, bearing 4, diameter progressive screw 5, screw rod cavity 6, nut 7, glue discharging mouth 8; The plastic squeeze head passes through reducing motor 17 through bush roller chaiin 20 driving main shaft 3, and drives the even glued membrane of exporting of Reducing screw bar 5 rotation realizations.At the uniform velocity the principle of the Webbing take-up device automatic coiling of tape is: according to V=π dn, make the glued membrane thickness even, linear velocity V must remain unchanged during winding.If keep variable-frequency motor 13 rotation speed n constant, linear velocity V increases along with the increase of winding diameter d, and the glued membrane thickness can not keep evenly.Want retention wire speed V constant, along with the increase of winding diameter d, variable-frequency motor 13 rotation speed n are wanted corresponding reduction, introduce variable-frequency motor 13 for this reason and solve this problem.Principle is that rotary encoder 21 feeds back to winding variable-frequency motor 13 to guarantee that the winding linear velocity is consistent all the time according to the tape transport linear velocity that measures, and winding variable-frequency motor 13 is through bush roller chaiin 20, the at the uniform velocity winding automatically of a pair of gear driven take-up spool.
