[0027] Among them, the connecting shell 71 is set in a concave block shape as a whole, and the upper and lower ends of the connecting shell 71 are respectively against the upper and lower sides of the transmission belt 4, ensuring that the connecting shell 71 can be stably connected to the transmission belt 4 and ensuring the stability of the subsequent tensioning adjustment process.

[0028] See also Figure 5 The rotation locking assembly 72 in this embodiment includes a connecting plate 721 bolted to the middle of the connecting shell 71, a ratchet 722 installed in the middle of the connecting plate 721 for rotation locking, a rotating shaft 723 docked at the middle of the ratchet 722 and connected to the middle of the two-way assembly 73, a spring spring 724 installed in the middle of the connecting plate 721 and connected to the inside of the ratchet 722, so that the ratchet 722 can be automatically reset and rotated through the rebound effect of the spring spring 724, a clip 725 clamped to the left side of the ratchet 722, a spring sheet 726 connected to the left side of the clip 725 for providing elastic clamping support, a first knob 727 docked at the front side of the ratchet 722, and a second knob 728 docked at the front side of the upper end of the clip 725.

[0029] Among them, the ratchet 722 is rotatably connected to the middle part of the connecting plate 721, and the inner side of the ratchet 722 is connected to the spring spring 724 to ensure that when the ratchet 722 realizes the simultaneous rotation of the rotating shaft 723, the spring spring 724 can be wound and compressed; the upper end of the clamping strip 725 is rotatably connected to the left side of the upper end of the inner part of the connecting shell 71, and the lower end of the clamping strip 725 is set in a smooth inclined block shape, so that the outer side of the clamping strip 725 can be easily inserted into the outer tooth angle of the ratchet 722 to realize the rotation locking activity of the ratchet 722; the first knob 727 and the second knob 728 are respectively inserted into the interior of the transmission frame 1, and there is a distance between the first knob 727 and the second knob 728.

[0030] See also Figure 6The two-way component 73 in this embodiment includes a rotating plate 731 rotatably connected to the inside of the connecting shell 71 and connected to the rear side of the rotating shaft 723, a connecting arm 732 symmetrically connected to the upper and lower sides of the rotating plate 731 to realize synchronous push-pull transmission, a docking block 733 docked at the side of the connecting arm 732 away from the rotating plate 731, and a movable seat 734 fastened to the outside of the docking block 733 and connected to the front side of the connecting shaft 74. In this way, the movable seat 734 can be pushed and pulled with the connecting arm 732 and move up and down. The support rods 735 on the left and right sides of the symmetrical movable seat 734 are used for moving guidance, and the compression springs 736 are correspondingly provided at the outer ends of the support rods 735 on both sides and resisted against the two sides of the movable seat 734.

[0031] Among them, the docking block 733, the movable seat 734, the support rod 735 and the compression spring 736 are all symmetrically arranged along the upper and lower inside of the connecting shell 71, and the middle part of the movable seat 734 is slidably embedded in the rear side of the connecting shell 71. In this way, the movable seat 734 can not only achieve stable movement, but also, through the guidance and elastic cooperation of the support rod 735 and the compression spring 736, perform stable movement and reset activities.

[0032] Here’s how it works:

[0033] When the transmission mechanism of the high-speed turning roller line is to be used, the main roller 2 installed in the middle of the transmission frame 1 on both sides can be operated to make the main roller 2 rotate. When the main roller 2 rotates, the driving wheel 3 connected to the front side of the main roller 2 will rotate synchronously, and cooperate with the transmission belt 4 connected on both sides of the outer end to drive the driven wheel 5 connected on the other side of the transmission belt 4 on both sides. In this way, the auxiliary rollers 6 provided on the left and right sides of the main roller 2 can rotate in the same direction. The main roller 2 can synchronously realize the same direction rotation of multiple auxiliary rollers 6 to assist in the turning transmission of objects.

[0034] When the main roller 2 and the auxiliary roller 6 rotate simultaneously and perform a turning transmission activity, in order to prevent the driving wheel 3 and the driven wheel 5 and the transmission belt 4 between the adjacent driven wheels 5 from slipping when performing a turning transmission of heavier objects, a convenient tensioning device 7 is provided on the outside of the transmission belt 4. That is, when the transmission belt 4 needs to be tightened, the first knob 727 can be turned to realize the counterclockwise rotation of the ratchet 722. As the ratchet 722 rotates, the rotating shaft 723 connected to the middle of the ratchet 722 can rotate in the same direction. At the same time, the spring 724 installed inside the ratchet 722 will perform a winding and compression activity accordingly. As the rotating shaft 723 rotates, the rotating plate 731 connected to the rear side of the rotating shaft 723 will be connected to the rotating shaft 723. The two sides of the movable base 734 are connected to each other by the movable base 734, and the movable base 734 is connected to the movable base 734. The movable base 734 is connected to the movable base 734 by the movable base 734. The movable base 734 is connected to the movable base 734. The two sides of the movable base 734 are connected to each other by ...

[0035] Secondly, during the counterclockwise rotation of the ratchet 722, the clip 725 connected to the left side of the ratchet 722 can intermittently stop the outer tooth angle of the ratchet 722 through the elastic support of the spring sheet 726 connected to the side. In this way, after the subsequent outer tensioning adjustment, the clip 725 locks the ratchet 722, ensuring that the winding spring 724 in the wound and compressed state inside the ratchet 722 cannot rebound, thereby ensuring the stability of the tensioning adjustment of the transmission belt 4 by the tensioning blocks 75 on both sides;

[0036] Furthermore, when the movable seats 734 on both sides are pulled by the connecting arms 732 on both sides and move relative to each other, the support rods 735 connected along the left and right sides are accurately moved, and at the same time, the compression springs 736 provided on the outside of the support rods 735 are squeezed, so that the compression springs 736 can be prepared for subsequent elastic reset.

[0037] When the tension adjustment state of the transmission belt 4 is to be released, the first knob 727 connected to the front side of the upper end of the card strip 725 is rotated clockwise to rotate the card strip 725 clockwise, releasing the lock with the outer tooth angle of the ratchet wheel 722. As a result, the spring spring 724 arranged inside the ratchet wheel 722 and in the wound and compressed state will rebound elastically and drive the ratchet wheel 722 to rotate clockwise. As a result, the rotating shaft 723 connected to the middle of the ratchet wheel 722 can realize the reset rotation of the rotating plate 731 connected to the rear side, so that the connecting arms 732 on both sides are pushed outward. The docking block 733 and the movable seats 734 on both sides will drive the tensioning block 75 arranged relatively on the rear side to perform reset movement to quickly release the tensioning adjustment state of the transmission belt 4. In addition, the compression spring 736 arranged on the outside of the support rod 735 and in a compressed state can also rebound at the same time to speed up the reset efficiency of the tensioning block 75. In this way, the flexible adjustment of the tensioning state of the transmission belt 4 can be conveniently achieved to meet the turning and transmission requirements of items of different weights, thereby ensuring the flexibility and efficiency of the overall use of the transmission mechanism of this high-speed turning roller line.
