Detailed Embodiments

[0018] As shown in the figure, on the basis of the original tensioning structure, the present utility model improves the tensioning wheel structure. The top inner side of the drive belt is tensioned by the upper support wheel, and the bottom outer side of the drive belt is tensioned by the eccentric wheel arranged on the adjustment shaft, and the effective adjustment of the tensioning degree can be realized. The specific structure is described as follows:

[0019] Embodiment 1:

[0020] A tensioning wheel structure of a beaming machine, as Figure 1 shown, which includes a driving wheel 1 and a driven wheel 2. A drive belt 3 is arranged between the driving wheel 1 and the driven wheel 2. The driving wheel 1 is connected to a gearbox or a motor, and the driven wheel 2 is fixed on a driven wheel chassis 21.

[0021] The drive belt 3 is arranged in a ring shape. An upper support wheel 42 is arranged in cooperation with the top inner side of the drive belt 3. As Figure 1 、 2 shown, the upper support wheel 42 is fixed by a support frame 4. A vertical long hole 41 is arranged on the support frame 4 to realize the vertical adjustment of the upper support wheel 42; the support frame 4 is fixed on a vertical plate 8 by a fixing block 81. In this embodiment, the drive belt 3 is a toothed belt, and the upper support wheel 42 cooperating with it is a sliding gear, and the upper support wheel 42 rotates meshingly with the drive belt 3 during support.

[0022] An outer support frame 5 is arranged on the bottom side of the drive belt 3. An outer adjustment groove 51 is arranged on the outer support frame 5. The outer adjustment groove 51 is arranged vertically and obliquely. A vertical adjustment cylinder 7 is arranged in cooperation with the outer adjustment groove 51. As Figure 3 、 4 shown, a central threaded hole is arranged inside the vertical adjustment cylinder 7, and a through hole 71 is arranged inside the central threaded hole. An external thread is arranged on an adjustment shaft 74 to cooperate with the central threaded hole; a smooth rod 76 is also arranged at the end of the adjustment shaft 74 for extrusion positioning in cooperation with a locking screw 72.

[0023] An eccentric wheel 73 is arranged at the outer end of the adjustment shaft; the locking screw 72 is arranged in the radial direction of the vertical adjustment cylinder 7, and the locking screw 72 penetrates through the vertical adjustment cylinder 7 to squeeze the adjustment shaft 74 to realize locking and positioning.

[0024] Furthermore, an adjustment surface is arranged on the adjustment shaft 74. In this embodiment, such an adjustment surface is a hexagonal adjustment surface 75 with a hexagonal structure. The design purpose is to facilitate tool clamping. An ordinary wrench can be used to screw the entire adjustment shaft 74 to realize the adjustment of the position of the eccentric wheel 73 in the vertical direction, and thus realize the adjustment of the tensioning degree.

[0025] Through the above structural arrangement, the utility model can achieve a large-scale adjustment of the vertical position of the eccentric wheel 73 by moving the vertical adjustment cylinder 7 up and down on the outer support frame 5. Because the above adjustment method is a large-stroke non-precise adjustment, after the adjustment is completed, it is necessary to achieve a small-stroke adjustment of the vertical position of the eccentric wheel 73 by screwing the entire adjustment shaft 74, thereby achieving precise adjustment of the tension degree.

[0026] Furthermore, the outer support frame 5 drives a positioning plate 52 to be horizontally welded on the top surface, a horizontal adjustment hole is provided on the positioning plate 52, a positioning rod 6 passes through the adjustment hole, a positioning ring 61 is provided at the bottom of the positioning rod 6, and a horizontal screw rod 9 for locking the vertical adjustment tube 7 passes through the positioning ring 61 and is locked and fixed with the vertical adjustment tube 7; an external thread is provided on the top of the positioning rod 6, and a positioning nut 62 is provided on the external thread.

[0027] Furthermore, the eccentric wheel 73 is a bearing eccentric wheel, and the width of the eccentric wheel 73 is greater than the width of the driving belt 3 . Even when the driving belt 3 is adjusted axially, it will not separate from the eccentric wheel 73 .

[0028] The vertical pulling and positioning of the positioning plate 52, the positioning nut 62, the positioning rod 6 and the positioning ring 61 can effectively ensure that the entire vertical adjustment cylinder 7 will not move vertically after being locked and positioned, and further promote the stability of the eccentric wheel 73 after being locked.

[0029] In summary, the utility model can realize the upper and lower synchronous support of the driving belt 3 through the cooperation of the upper support wheel 42 and the eccentric wheel 73 through the above structural setting, and the tension tightness can be adjusted by adjusting the support position of the upper support wheel 42 and the eccentric wheel 73.
