Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

Example 1

As shown in Figure 1, a label conveying device includes a power mechanism 1, a feeding mechanism 2, a feeding mechanism 3 and a frame 4. The feeding mechanism 2 has a conveying platform, and the label belt 5 is located on the conveying platform. Driven by the feeding mechanism The lower label belt 5 moves forward, and the power mechanism is arranged on the side of the frame 4 to provide power to the feeding mechanism; the feeding mechanism is arranged above the conveying platform to smooth the label belt. The label belt 5 moves forward on the conveying platform under the drive of the feeding mechanism 2, and the feeding mechanism ensures that the label does not wrinkle during the movement and keeps it flat.

As shown in Figure 2-3, the feeding mechanism includes an elastic table 21, an upper roller 22, a lower roller 23 and a lifting cylinder 25. The elastic table 21 constitutes a conveying platform, and a positioning magnet 24 is arranged on the elastic table 21 for positioning The magnet 24 is adsorbed on the surface of the elastic table 21 by magnetic force, and the positioning magnet 24 defines the fixed position of the label tape 5 to keep the label tape 5 from shifting during the movement. The upper roller 22 is located on one side of the elastic table 21 and is installed on the frame 4, the lower roller 23 is directly opposite to the upper roller 22 and the lower roller 23 is installed on the side of the elastic table 21, and the lifting cylinder 25 is provided At the lower part of the elastic table 21 , the lifting cylinder 25 lifts the elastic table 21 upward, and then drives the lower roller 23 to rise, so that the lower roller 23 abuts the upper roller 22 and maintains a certain pressure to adapt to labels of different thicknesses. During movement, the label tape 5 moves forward under the friction of the upper and lower rollers, and the positioning magnet 24 restricts the position of the label tape 5 from shifting.

As shown in FIG. 4 , the power mechanism includes a motor 11, a synchronous wheel 12 and a synchronous belt 13. A synchronous wheel 12 is installed on the motor 11 and the upper roller 22 respectively. The synchronous belt 13 connects the two, and the rotation of the motor 11 drives the upper roller 22 to rotate. , the synchronous wheel 12 and the synchronous belt 13 are connected by a tooth shape, so that the teeth can not jump or slide during the movement process, and the conveying accuracy can be ensured. An encoder is installed at the rear end of the motor 11 for servo control to ensure the conveying accuracy.

As shown in FIG. 5 , the feeding structure includes a feeding pressing plate 31 and a retainer 32 , the retaining frame 32 is fixed on the frame 4 , and the feeding pressing plate 31 is hingedly mounted on the retaining frame 32 through a pin shaft. During the moving process, the pressing plate 31 presses on the label tape 5 due to gravity, so as to ensure that the label tape will not be wrinkled and kept flat during the conveying process. In addition, the lower end of the pressing plate 31 near the label tape 5 has a slope, and the groove faces the direction in which the label tape 5 is sent, so that the label tape can easily enter the pressing plate 31 and be gradually pressed tightly.

The working process of the entire label conveying device is as follows: the power mechanism 1 provides power for the device, and an encoder is installed at the rear end of the motor to ensure the running accuracy of the motor to improve the accuracy of the whole machine. The motor 11 drives the upper roller 22 through the synchronous wheel 12 and the synchronous belt 13. Rolling, the label tape 5 is moved forward by friction; the upper roller 22 and the lower roller 23 are close to each other to squeeze the label tape 5, and the constant pressure is maintained by the lifting cylinder 25, so that the friction force is the same, the accuracy is improved, and the lifting cylinder The elastic table 21 is jacked up so that the lower roller 23 is close to the upper roller 22, and since the elastic table can be slightly deformed, the shape of the label tape 5 with different thickness can be changed to ensure the pressure. The positioning magnet 24 is placed on the elastic worktable 21 to ensure that the label tape 5 will not be offset during the advancing process, thereby increasing the product qualification rate. The material pressing plate is pressed on the label belt 5 under the action of its own weight, and due to the special arc groove design, the label belt 5 gradually shrinks and adheres to the surface of the elastic work table 21 during the advancing process, smoothes the label belt, and ensures the smoothness of the label belt after conveying. The label tape is flat.

Those skilled in the art will recognize that, without departing from the scope of protection of the present invention, various modifications, changes and combinations can be made to the above-described embodiments, and such modifications, changes and combinations are considered to be original ideas within the range.
