The following embodiments will further describe the related technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of patent application of the present invention. The description is as follows:

As shown in FIGS. 1 to 3, the conveying module 100 with a tension adjustment mechanism according to an embodiment of the present invention includes: a plurality of transmission rollers 1, a power supply mechanism 2, a tension detection mechanism 3, a tension adjustment mechanism 4, and a control mechanism 5. .

The plural conveying rollers 1 are arranged along a conveying direction d. The transmission roller 1 includes at least one power wheel 11 and a plurality of free wheels 12, and the conveying direction d has a feed end d1 and a discharge end d2. The power wheel 11 is a roller directly connected to the power supply mechanism 2 and rotates by the power of the power supply mechanism 2. The free wheel 12 is not directly connected to the power supply mechanism 2, and the rotation of the free wheel 12 depends on the indirect drive of the material belt T.

In FIG. 1, the freewheel 12 and the material belt T in the lower row are omitted. In FIG. 3, a plurality of free wheels 12 arranged up and down and the material tape T wound thereon are shown, and the power wheel 11 is located downstream of the free wheels 12. The material belt T is rotated by the power wheel 11, and its tension also pulls the free wheel 12 located upstream, so that the material belt T is transmitted between the rollers.

The power supply mechanism 2 is, for example, a motor.

The tension detection mechanism 3 is connected to at least one of the free wheels 12. In this embodiment, the tension detection mechanism 3 is connected to the rotating shaft of the freewheel 12. The tension detection mechanism 3 can detect the detection result of the tension of the material belt T according to the rotation speed and angular velocity of the rotating shaft of the free wheel 12. However, the present invention is not limited to this. The tension detection mechanism 3 can be arranged at other positions of the free wheel 12 and the detection result of the tension of the material belt T can be measured according to the physical change of the free wheel 12.

The tension adjustment mechanism 4 is provided at the feeding end d1 in the conveying direction d. The tension adjusting mechanism 4 includes a rod 41 and a weight member 42 sleeved on the end of the rod 41. The center of mass of the weight member 42 and the rod 41 are not on the same axis. The material tape T will pass through the rod 41 before entering the inside of the conveying module.

The control mechanism 5 signals the tension detection mechanism 3 and the tension adjustment mechanism 4, and controls the position of the counterweight member 42 relative to the rod 41 according to a detection result of the tension detection mechanism 3.

For example, as shown in Figures 4A and 4B, when the tension value of the detection result of the tension detection mechanism 3 exceeds a predetermined range (that is, the tension is too large), the control mechanism 5 controls the counterweight member 42 to deflect in the reverse direction (in the figure) 4B is the counterclockwise direction, and the conveying direction d relative to the material belt T is reverse yaw). Since the counterweight member 42 is movably sleeved on the rod 41, when the counterweight member 42 deflects in the opposite direction, the rod 41 will correspondingly rotate in the forward direction (clockwise rotation direction as shown in FIG. 4B) , This process will feed an extra section of the material belt into the conveying module, and the speed of the rollers in front of this section of the material belt remains unchanged, so after adding this section of material belt, the overall tension of the material belt T is relaxed .

As shown in FIGS. 4A and 4C, when the tension value of the detection result of the tension detection mechanism 3 is lower than a predetermined range (that is, the tension is too small), the control mechanism 5 controls the counterweight member 42 to swing forward (in FIG. 4C) It is a clockwise direction, and the conveying direction d of the relative material belt T is a forward deflection). Since the counterweight member 42 is movably sleeved on the rod 41, when the counterweight member 42 yaws in the forward direction, the rod 41 will correspondingly rotate in the opposite direction (the counterclockwise rotation direction as shown in FIG. 4C) This process is like returning a section of the material belt to the outside of the conveying module, and the speed of the rollers in front of the section of the material belt remains unchanged. Therefore, after the section of material belt is returned, the material belt T is tightened, and the material belt T is as a whole The tension rises.

Through the conveying module 100 with a tension adjustment mechanism of the present invention, the tension of the conveyed tape T can be detected in real time, and the tape tension can be appropriately adjusted according to the condition of the detection result. The adjustment process is fully automatic, without stopping, and reducing production costs. And improve production yield.

Further, in an embodiment, the control mechanism 5 controls the yaw angle of the counterweight member 42 according to the tension value of the detection result of the tension detection mechanism 3. For example, if the measured tension value deviates too much from the predetermined range, the deflection angle is increased; if the tension value is only slightly different from the predetermined range, only a certain small angle is deflected. In this way, the adjustment of the tension value and the deflection angle are quantified, and the tension value can be adjusted more finely.
