The technical problem to be solved by the utility model is to provide a multi-head active coating machine with simple structure and high production efficiency.

In order to solve the above-mentioned technical problems, the utility model provides a multi-head active coating machine, including: a frame, and a set of mold-feeding guide rollers arranged in a straight line on the frame and used to pass through multiple cable core wires And the eye mold frame, a plurality of film release heads for setting the film rolls on the upper and lower sides of the eye mold frame, and a guide for transferring the film tape to the eye mold frame on one side of each film release head Roller set; the eye frame is provided with a coating nozzle for coating the film tape on the cable core.

Further, the rotating shaft of the unwinding head for setting the film roll is connected to the output shaft of an unwinding motor; the guide roller group is provided with a motor for controlling the speed of the unwinding motor according to the swing to keep the tension of the film tape balanced. Tension swing device.

Further, one side of the film releasing head is provided with a film releasing tracking rod for controlling the speed of the unwinding motor by monitoring the thickness of the film roll.

Further, the front end of the mold-entry guide roller set is provided with a line-entry guide wheel set.

Further, the tension pendulum device is connected to an encoder, and the encoder is connected to a PLC for controlling the rotation speed of the unwinding motor and maintaining the tension of the film tape. That is to say, as the thickness of the film roll is lower, only need to increase the rotation speed of the unwinding motor to maintain the speed of the coating operation.

Compared with the prior art, the above-mentioned technical solution of the utility model has the following advantages: the multi-head active coating machine of the utility model can simultaneously carry out the coating operation on four core wires at one time, and adopts a motor to control the coating tension, so that during the operation process The tension of the film is stable, and the size of the tension is adjusted according to the twist length of the host machine and the feedback of the film tension tracking mechanism to adjust the film release speed of the motor. The wire that needs to be completed by multiple processes can be solved at one time on this equipment.

Description of drawings

In order to make the content of the utility model easier to understand clearly, the utility model will be further described in detail according to the specific embodiments below in conjunction with the accompanying drawings, wherein

Fig. 1 is the front appearance structural drawing of multi-head active coating machine of the present utility model;

Fig. 2 is a side view of the above-mentioned multi-head active coating machine.

Detailed ways

As shown in Figure 1-2, the multi-head active coating machine of this embodiment includes: a frame 2, a mold-in guide roller group 7 arranged on the frame 2 and distributed in a straight line from front to back for passing through multiple cable core wires, and Eye mold frame 5, a plurality of film release heads 3 for setting film tape rolls arranged on the upper and lower sides of eye mold frame 5, and film tapes on one side of each film release head 3 are used to transfer film tape to eye mold frame The guide roller group 9 in 5; the eye mold frame 5 is provided with a coating nozzle for coating the film tape on the cable core.

The rotating shaft of the film unwinding head 3 that is used to set the film tape roll is connected to the output shaft of an unwinding motor 1; the guide roller group 9 is provided with a motor for controlling the speed of the unwinding motor according to the swing to keep the tension of the film tape balanced. The tension pendulum device 4.

One side of the film releasing head 3 is provided with a film releasing tracking rod 6 for controlling the speed of the unwinding motor 1 by monitoring the thickness of the film roll.

The front end of the mold entry guide roller group 7 is provided with a line entry guide wheel group 8 .

The tension lever device 4 is connected to an encoder 10, and the encoder 10 is connected to a PLC for controlling the rotation speed of the unwinding motor 1 and maintaining the tension of the film tape.

The film may be a paper film, an aluminum film, or the like.

The number of film releasing heads 2 and corresponding guide roller groups 4 is consistent with the number of cable core wires to be coated.

Therefore, if only three cable core wires need to be coated, only three film releasing heads 3 and corresponding three sets of guide roller groups 9 need to be used.

As a four-head active coating machine, the working principle is as follows: the four core wires enter from the wire-entry end, and then enter the coating area after being shunted by the wire-entry guide wheel group. The film is released from the film release head, passes through the film frame, the transverse guide roller group, the small guide roller group, the tension pendulum device, the large guide roller group, and the mold guide roller group, and then enters the coating area to feed the core line. Carry out the coating operation (the membrane passing line is shown in Figure 1).

Film tension control: the swing amplitude of the swing rod on the tension swing rod device 4 is changed, and the angle data of the encoder 10 is fed back to the PLC, and the film unwinding speed of the unwinding motor 1 is adjusted through the PLC data processing output to adjust the film tension. That is, the tension of the film tape is stable, so that the film is not stretched during the bagging process and always keeps the film flat before wrapping, so as to keep the wrapping surface smooth and free from burrs when the film is wrapped on the core wire. The film release tracking rod 6 is used to track the film release radius. By tracking the change of the film release radius, the speed of the film discharge speed is adjusted to achieve a stable film discharge line speed, so that the coating process will not be caused by the radius of the film disc. Reduce the impact on the film tension; in addition, it can be judged whether the film is finished according to the tracking of the film radius, so as to achieve the replacement of the film at a fixed time.

Apparently, the above-mentioned embodiments are only examples for clearly illustrating the utility model, rather than limiting the implementation manner of the utility model. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And these obvious changes or variations derived from the spirit of the present utility model are still within the protection scope of the present utility model.
