And starting material receiving operation when the side film materials are conveyed to the end.

Material receiving:

s1, enabling one end of the film material to be connected to sequentially pass through the first guide roller, the cutting device and the ultrasonic wave generating device on the side, and enabling the end part of the film material to be lower than the ultrasonic wave generating device;

s2, controlling the movable roller to move by a driving mechanism to release the film material;

s3, starting the ultrasonic generating device, and bonding the membrane materials on the two sides;

s4, starting a cutting device, and cutting off the redundant membrane material on the other side;

and S5, controlling the movable roller to return to the initial position by the driving mechanism.

In step S1, passing one end of the film material 7 to be inserted on the feeding roller 6 through the third guide roller 8, the gap between the fifth roller 10 and the first guide roller 9, the cutting device 11 and the ultrasonic generating device in sequence, wherein the film material is positioned between the rodless cylinder 111 and the cutting seat 113 when passing through the cutting device 11, and the film material is positioned between the ultrasonic assembly 13 and the pressing block 132 when passing through the ultrasonic generating device; the end of the film material 7 is made lower than the ultrasonic wave generating device.

In step S4, the cutting device 11 on the opposite side of the incoming side starts to move, the rodless cylinder 111 drives the cutter 112 to move along the direction of the knife channel 1131 to cut the remaining film 7 on the opposite side of the incoming side, after the cutting is completed, the cutter 112 immediately returns along the knife channel 1131, the cutting device 11 recovers, and the bonding of the two groups of film is completed.

The non-stop ultrasonic film material receiving method uses the non-stop ultrasonic material receiving machine, when receiving the material, the film material is released by controlling the movement of the movable roller 54 in the storage rack 5, so that the film material at the output end of the storage rack 5 is continuously output, and the film material at the input end of the storage rack 5 keeps static; in the time that the membrane material that releases was consumed in this section of time of storage frame 5, ultrasonic wave generating device accomplished the bonding to the membrane material, and cutting device 11 accomplishes the excision to the side excess part of joining in to the membrane material, and whole process has reached the continuous purpose of connecing the membrane material of not shutting down, has avoided the original condition of manual material that connects again that needs to shut down, has improved production efficiency. Wherein the starting and operation of the motor 51, the ultrasonic wave generating device and the cutting device 11 are automatically controlled by an external control system.

Wherein, the release process of the membrane material in the step S2 is as follows:

s2.1, driving a screw rod 52 to rotate by a motor 51;

s2.2, the screw rod 52 drives the sliding block 53 to move towards the opposite side fixed roller 55;

s2.3, the sliding block 55 drives the movable roller 54 to move towards the opposite side fixed roller 55 along the sliding groove 16, and the film material is released;

the motor 51 and the screw rod 52 are used for driving so as to control the moving speed of the movable roller 54, the sliding groove 16 is used for limiting the sliding block 53, and the sliding block can only move along the direction of the sliding groove 16, so that the movable roller 54 can be far away from or close to the opposite fixed roller 55 at a certain speed.

Wherein the moving speed of the movable roller 54 in step S2.3 is one half of the film material output speed.

For the moving speed of the movable storage rack roller 54, if the speed is too low, the film material is pulled by the output end of the storage rack 5, so that the tension applied to the film material is increased, the film material is damaged, and the product quality is affected; if the speed is too high, the film cannot be guided to the roller to be stretched straightly, and the conveying of the film is influenced, so that the moving speed of the movable roller 54 has specific requirements.

Referring to fig. 8, the output of the film material is a constant speed output, and the speed is represented by v; the time required for receiving the materials is fixed time, t represents the required time, the output length of the film materials is vt within the time t during receiving the materials, and the storage rack 5 needs to release the film materials with the length vt (the dotted line part in fig. 8) within the time t to meet the output requirement; the movable roller 54 in the storage rack 5 moves to the opposite fixed roller 55 by a unit length distance to release two unit lengths of film materials, because the upper part and the lower part of the movable roller 54 release one unit length of film materials; therefore, the movable roller 54 needs to move to the opposite fixed roller by a distance of vt/2 within the time t, and the movable roller 54 also needs to move at a constant speed in order to keep consistent with the film material output speed, wherein the speed is (vt/2)/t is equal to v/2, namely, half of the film material output speed.

The recovery process of the movable roller in the step S5 is as follows:

s5.1, driving the screw rod 52 to rotate by the motor 5;

s5.2, the screw rod 52 drives the sliding block 53 to be far away from the opposite side fixed roller 55;

s5.3, the sliding block 53 drives the movable roller 54 to be away from the opposite side fixed roller 55, and the movable roller returns to the initial state.

The membrane material of storage frame 5 input connects in material loading roller 6 through each guide roller, and when the fixed roller 55 of offside was kept away from gradually to activity roller 54, the membrane material of storage frame 5 input received and was dragged, and the rotational speed of material loading roller 6 can accelerate in order to release more membrane materials, and the membrane material can not receive the tension that is enough to influence its quality.
