The adjustment structure includes: a pressure roller 23, an adjustment chamber 30 and an adjustment block 33. The pressure roller 23 is movably connected to the front wall of the bracket 20, and the adjustment chamber 30 is fixedly connected to the top of the bracket 20. The adjustment chamber 30 is a hollow rectangular box in the cavity. The adjustment block 33 is slidably connected in the cavity of the adjustment chamber 30. The pressure roller 23 is rotatably connected to the front wall of the adjustment block 33. The pressure roller 23 is cylindrical, and the curved surface of the pressure roller 23 can contact the top of the transmission belt 22.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a rectangular notch is provided on the top of the bracket 20, the adjustment chamber 30 is fixedly connected in the notch on the top of the bracket 20, the adjustment block 33 slides vertically in the cavity of the adjustment chamber 30, and the cavity of the adjustment chamber 30 can adapt to the size of the adjustment block 33. The adjustment structure also includes a pressure groove 31, an adjustment groove 32 and a spring block 34. The pressure groove 31 passes through the front wall of the adjustment chamber 30, the pressure roller 23 can pass through the pressure groove 31 and connect with the front wall of the adjustment block 33, and the adjustment groove 32 is in the adjustment chamber The cavity 30 is symmetrically opened on both sides, and a plurality of adjustment grooves 32 are evenly opened vertically in the cavity 30 of the adjustment chamber. The spring block 34 is symmetrically elastically connected to the wall surfaces of the two sides of the adjustment block 33 by springs. The pressure roller 23 can slide vertically in the pressure groove 31. The adjustment groove 32 is a semicircular groove, and the spring block 34 is a semi-capsule-shaped block. The two sides of the adjustment block 33 are symmetrically opened with circular grooves adapted to the spring block 34. The symmetrical spring blocks 34 are respectively arranged in the symmetrical grooves. The adjustment grooves 32 can adapt to the arc of the spring block 34. The adjustment structure further includes a slide groove 35, a handle 36, a locking block 37, a locking rod 38 and a locking groove 39. The slide groove 35 is opened at the top of the adjustment block 33, the handle 36 is fixedly connected to the rear wall of the adjustment block 33, the locking block 37 is slidably connected to the top of the adjustment block 33, the locking rod 38 is fixedly connected to the rear wall of the locking block 37, and the locking groove 39 is opened on the rear wall of the adjustment chamber 30. The slide groove 35 is a convex groove, and the slide groove 35 can adapt to the lower half of the size of the locking block 37. The lower half of the locking block 37 can slide horizontally in the slide groove 35. The top of the locking rod 38 is U-shaped. The locking groove 39 is composed of a large rectangular groove and a plurality of small rectangular grooves. The locking groove 39 is opened parallel to the rear wall of the adjustment chamber 30. The two ends of one side of the locking rod 38 can slide in the parallel locking grooves 39. The small rectangular groove in the locking groove 39 can adapt to the thickness of the locking rod 38. The locking rod 38 can slide vertically up and down in the large rectangular groove of the locking groove 39.

[0030] When in use, when the transmission belt 22 is relatively loose on the symmetrical roller 21, first slide the locking rod 38 into the large rectangular groove of the locking groove 39. When sliding the locking rod 38, the locking block 37 will be driven to slide horizontally in the slide groove 35. When the locking rod 38 slides into the large rectangular groove of the locking groove 39, it will separate from the small rectangular groove of the locking groove 39. At this time, turn the handle 36 downward, the handle 36 will drive the adjustment block 33 to slide vertically in the cavity of the adjustment chamber 30, and the adjustment chamber 30 will drive the locking block 37 and the locking rod 38 to slide at the same time. The adjustment block 33 will also drive the pressure roller 23 to move. When the transmission belt 22 is tightened, the handle 36 is pushed downward to drive the pressure roller 23 to press the upper part of the transmission belt 22 so that the transmission belt 22 is tightened between the symmetrical rollers 21. When the adjustment block 33 is slid, the spring block 34 will also move to each corresponding adjustment slot 32 with the sliding of the adjustment block 33 to preliminarily fix the position of the adjustment block 33. When the adjustment block 33 slides to the desired position, the locking rod 38 can be slid into the small rectangular slot of the locking slot 39. After the locking rod 38 slides into the small rectangular slot of the locking slot 39, the position of the adjustment block 33 will be fixed, thereby fixing the position of the pressure roller 23.

[0031] To summarize, by setting up an adjustment structure, the tightness of the transmission belt 22 between the symmetrical rollers 21 can be quickly adjusted. The adjustment structure can adjust the position of the pressure roller 23 by toggling and sliding, thereby completing the tensioning of the transmission belt 22 on the wall of the roller 21. This adjustment process only requires sliding the handle 36 and the locking rod 38 to complete, so compared with the prior art, this solution is faster in adjustment.

[0032] like Figure 5 As shown, the adjustment structure further includes a receiving groove 40 and a clamping rod 41. The receiving groove 40 is provided at the bottom of one side of the locking rod 38. The clamping rod 41 is rotatably connected in the receiving groove 40. The locking rod 38 is located above the handle 36. When the receiving groove 40 is rotated to a vertical state, a side wall of the clamping rod 41 can contact a side wall of the handle 36. When the clamping rod 41 is in a horizontal state in the receiving groove 40, the bottom of the clamping rod 41 is flush with the locking rod 38.

[0033] When in use, after the locking rod 38 is slid into the small rectangular groove of the locking groove 39, the locking rod 41 is flipped downward from the receiving groove 40 to a vertical state. At this time, the side wall surface of the locking rod 41 will contact the wall surface of the handle 36 to fix the position of the locking rod 38;

[0034] In summary, by providing the locking rod 41, it is possible to prevent the locking rod 38 from automatically sliding on the top of the handle 36 and causing tensioning failure, thereby improving the stability of the device operation and reducing the failure rate.

[0035] Working principle: When the transmission belt 22 is relatively loose on the symmetrical roller 21, first slide the locking rod 38 into the large rectangular groove of the locking groove 39. When sliding the locking rod 38, the locking block 37 will be driven to slide horizontally in the slide groove 35. When the locking rod 38 slides into the large rectangular groove of the locking groove 39, it will separate from the small rectangular groove of the locking groove 39. At this time, turn the handle 36 downward, and the handle 36 will drive the adjustment block 33 to slide vertically in the cavity of the adjustment chamber 30. The adjustment chamber 30 will drive the locking block 37 and the locking rod 38 to slide at the same time. The adjustment block 33 will also drive the pressure roller 23 to move. When the driving belt 22 is tightened, the handle 36 is pushed downward to drive the pressure roller 23 to press the upper part of the driving belt 22, so that the driving belt 22 is tightened between the symmetrical rollers 21. When the adjustment block 33 is slid, the spring block 34 will also move to each corresponding adjustment groove 32 with the sliding of the adjustment block 33 to preliminarily fix the position of the adjustment block 33. When the adjustment block 33 slides to the desired position, the locking rod 38 can be slid into the small rectangular groove of the locking groove 39. After the locking rod 38 slides into the small rectangular groove of the locking groove 39, the position of the adjustment block 33 will be fixed, thereby fixing the position of the pressure roller 23.
