The beneficial effects of the utility model are:

1, feed laborsaving: utilize motor to drive swing arm deflection, swing arm is dropped to low level by when filling with substance, directly stock roll is rolled to the front end of swing arm, and is placed in the groove of swing arm by the rolling of the roller at raw material axle two ends, then swing arm is upwards rotated until stock roll leans against on rubber roll, completes material loading.Very laborsaving, eliminate charging machinery, save cost and occupation of land.

2, energy consumption is low: after stock roll is raised to a high position, roller on raw material axle swings to rubber roll together with swing arm, make stock roll (relying on the weight of self) and rubber roll close contact, rubber roll rotates and utilizes frictional force to drive stock roll to rotate, raw material film simultaneously in stock roll, being pulled by two rubber rolls clampings, also can pull stock roll to rotate, so downwards, stock roll does not just need special power set to drive in whole production process, has saved the energy and production cost.In addition, shut down or intermediate hold time, rubber roll has the effect of brake to stock roll, prevents stock roll to be rotated further under the effect of inertia and causes raw material film superposed fold.

3, simplify the structure: because stock roll directly contacts with rubber roll, there is not the problem that raw material film is overlapping curling between the two in raw material film and rubber roll synchronous axial system, this just eliminates the mechanism of stretching film, simplifies the structure, reduces manufacturing cost.

4, by wider groove and the position switch being located at groove both sides, coordinate infrared sensor and swing arm upper limit position switch can control the minimizing progressively forward rocking motion of swing arm along with raw material again, avoid the excessive stock roll impact rubber roll that directly makes of amplitude of fluctuation to cause damage to rubber roll.
