Roller 6, the closed conveyor belt 7 is supported between the two supporting plates 2 through each supporting rotating roller 3 and the supporting rotating roller 3, and the middle part of the lower part of the conveyor belt 7 is supported on the upper side of the active rotating roller 6, and the active rotating The two symmetrical pressing rollers 8 above the rollers 6 press the conveyor belt 7 on the active rollers 6, and the upper edges and the left and right edges of the two support plates 2 are respectively fixed with an integrated slide rail 9 with a width greater than the thickness of the support plate 2. , the slide rails 9 on the front and rear sides are respectively sleeved with a plurality of fixed sliders 10 that are clamped on the slide rails 9, and each slider 10 is respectively fixed with a tie-rope fixing ear 11, through which the power cord of the geared motor 5 passes The motor control switch provided on the one side support plate 2 is connected with the external power supply and is electrically connected.

In order to facilitate the adjustment of each pressing roller 8 to press down the conveyor belt 7, the conveyor belt 7 can be pressed more firmly on the surface of the driving roller 6, and the friction force with the driving roller 6 is increased. The two ends respectively penetrate the vertical elongated adjustment holes 12 of the side walls of the support plate 2 on the front and rear sides, and the two ends of each pressing roller 8 are respectively inserted into the lift plates 13, and the lift plates 13 are respectively located on the support plate 2. A horizontal fixing plate 14 is fixed on the outer side wall of the support plate 2 below the lifting plate 13, and each fixing plate 14 is respectively penetrated and screwed with a vertical tensioning threaded rod 15. The upper end is penetrated and screwed into the lifting plate 13, so that each lifting plate 13 is supported above the corresponding fixing plate 14 through the tightening threaded rod 15, so that the two ends can be fixed on the lifting plate by rotating the tightening threaded rod 15. The pressing roller 8 on the 13 moves downward, which not only increases the friction between the conveyor belt 7 and the driving roller 6, but also increases the contact area between the two, which is convenient for the driving roller 6 to drive the conveyor belt 7 to rotate.

In order to facilitate the sliding block 10 to move on the sliding rail 9 , freely rotatable support balls 16 are embedded in the sliding block 10 on the upper and lower sides of the sliding rail 9 respectively.
