The elastic press wheel device
Technical field
The utility model relates to a kind of frock that is used on the coiling adhesive tape wrapping machine, more specifically to being used for the elastic press wheel device of pressure holding adhesive tape on the automatic adhesive tape wrapping machine.
Background technology
Technical at the automatic encapsulate band of coil, generally be earlier the sticking one side of adhesive tape to be placed on above the coil, pushing down adhesive tape with pinch roller then makes it fully to contact with coil, rotating coil makes adhesive tape wrap coil again, therefore press for a kind of can the rotation with coil, the pressing wheel device that pressure is more stable again can be risen and fallen and knee-action with coil.
The utility model content
The purpose of this utility model provides a kind of simple in structure, reliable operation, the elastic press wheel device that pressure is more stable.
In order to reach above-mentioned requirements, the technical scheme that the utility model adopted is: it is characterized in that it includes the rubber tire of pushing down coil, rubber tire is fixed on the outer ring of bearing, the inner ring of bearing is fixed on the lifting arm, described lifting arm is fixed in the chute, lifting arm moves in chute, be fixed with the upper spring fixed lever in the upper end of lifting arm, the upper end of spring is fixed on the upper spring fixed lever, the lower end of spring is fixed on the lower spring fixed lever below the upper spring fixed lever, rubber tire, is pressed on the coil downwards under the stretching of spring with lifting arm, and with coil to rolling.
The inner ring of described bearing is fixing with lifting arm again through the rubber tire mounting panel.
Described rubber tire adopts neoprene to make.
Described chute is connected with fixed head.
Elastic press wheel device according to such scheme is made has rubber tire good springiness, pressure stability, and contact area is big, and is simple in structure, and adhesive tape that is wrapped and coil are fitted closely, the steady quality of encapsulate, reliable advantage.

Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 to Fig. 4 is the structural representation of elastic press wheel device, and as seen from the figure, it includes the rubber tire 2 of pushing down coil 1, and rubber tire 2 adopts neoprene to make.Rubber tire 2 is fixed on the outer ring of bearing 3, and the inner ring of bearing 3 is fixed on the lifting arm 5 through rubber tire mounting panel 4, and described lifting arm 5 is fixed in the chute 6, and lifting arm 5 moves in chute 6, and described chute 6 is connected with fixed head 7.Be fixed with upper spring fixed lever 8 in the upper end of lifting arm 5, the upper end of spring 9 is fixed on the upper spring fixed lever 8, the lower end of spring 9 is fixed on the lower spring fixed lever 10 below the upper spring fixed lever 8, rubber tire 2 with lifting arm 5 under the stretching of spring 9, be pressed on downwards on the coil 1, and roll with 1 pair of coil.
Using method is: earlier coil 1 is fixed on the rotation axis 11, adhesive tape 12 places between rubber tire 2 and the coil 1 as shown in Figure 1, then rubber tire 2 and coil 1 are compressed, adhesive tape 12 is subjected to the pressure of rubber tire 2, fit tightly with coil 1, spring 9 is stretched as shown in the figure 2, rotation rotation axis 11, coil 1 rolls with 2 pairs of rubber tires, and the adhesive tape 12 between coil 1 and the rubber tire 2 is wrapped on the coil 1 as shown in the figure 4.When coil 1 rotated, rubber tire 2 moved up and down the thrust of maintenance to adhesive tape 12 owing to be subjected to the active force of spring 9 with coil 1.
