With reference to fig. 2 and 4, the front mounting plate 2 and the rear mounting plate 3 have substantially the same structure; taking the front mounting plate 2 as an example, a connecting bracket is arranged below one end of the front mounting plate 2, a transmission shaft is connected through the connecting bracket, a rotating shaft bracket is also arranged outside the rotating shaft, a rotating bearing is arranged in the rotating shaft bracket, and the rotating shaft bracket is fixed on the frame 1 of the packing machine; the transmission shaft is the power shaft, calls it as first transmission shaft 5 in this embodiment, and first transmission shaft 5 still is equipped with the connection spoke outside the runing rest, connects the spoke overcoat and has power belt, connects the power supply that is located the casing below through power belt, and the power supply generally is driving motor, rotates through driving motor and drives first transmission shaft 5 and rotate. A mounting groove 21 is formed in the front mounting plate 2, and a rotating shaft bracket fixed on the front mounting plate 2 is also arranged at two ends in the mounting groove 21, but the rotating shaft bracket is far smaller than an external rotating shaft bracket; a second transmission shaft 4 is arranged in the rotating shaft support, the specification of the second transmission shaft 4 is far smaller than that of the first transmission shaft 5, the second transmission shaft 4 is a driven shaft, the conveying belt 24 is arranged between the first transmission shaft 5 and the second transmission shaft 4, meanwhile, the conveying belt 24 is coated on the front mounting plate 2 between the first transmission shaft 5 and the second transmission shaft 4, at the moment, the front mounting plate 2 between the first transmission shaft 5 and the second transmission shaft 4 is the conveying table top 23, and a user places an object on the conveying table top 23 and conveys the object to a belt frame through the conveying belt 24; the conveying table 23 is also fixed with a nylon plate 22, the nylon plate 22 is fixed on the front mounting plate 2 through screws, and the nylon plate 22 can better protect the conveying belt 24 and prevent the conveying belt 24 from contacting with sharp parts on the front mounting plate 2.

Meanwhile, as shown in fig. 3, a tensioning structure is arranged on the lower end surface of the front mounting plate 2, the tensioning structure comprises a tensioning wheel 71, tensioning brackets 72 are arranged on the left and right sides of the tensioning wheel 71, and the tensioning brackets 72 are fixed on the front mounting plate 2 on the two sides of the conveying table 23 through fasteners, so that the tensioning wheel 71 abuts against the conveying belt 24 on the conveying table 23 for tensioning. The tensioning bracket 72 is further provided with a position adjusting groove 721 which is a transverse groove for supporting the front and back direction in the tensioning bracket 72, two ends of the tensioning wheel 71 respectively penetrate through the position adjusting grooves 721 at two sides, and the outer end of the tensioning wheel 71 is provided with a nut member for limiting and fixing. The user can make the tension pulley 71 in different states by adjusting the positions of both ends of the tension pulley 71 in the both side position adjusting grooves 721; specifically, by making the tension pulley 71 closer to the one-side transmission shaft to make the transmission belt tighter, or by adjusting the position of one end of the tension pulley 71 in the position adjustment slot 721 to make the tension pulley 71 offset, the offset tension pulley 71 can adjust the offset condition of the conveying belt 24 on the basis of the tension, i.e., if the conveying belt 24 is offset in operation, the user sets a tension pulley 71 with an opposite offset direction to compensate the offset angle of the conveying belt 24.

Because the thickness of the second transmission shaft 4 is much smaller than that of the first transmission shaft 5, after the conveying belt 24 is tensioned, the second transmission shaft 4 can be bent due to belt abutment or other uncertain factors after long-term operation, and the second transmission shaft 4 is seriously damaged and broken; the bending of the secondary drive shaft 4 affects the operation of the conveyor belt 24, causing the belt to shift, and affecting the transport and packing of the articles. The support rod 6 is abutted against the transmission shaft, and the support rod 6 is used for supporting force, so that the stress of the transmission shaft is reduced, and the influence of the bending of the transmission shaft on use is prevented.

Further, the transmission shaft includes an inner shaft 41 and a plurality of rolling members 42 disposed outside the inner shaft 41, the rolling members 42 abut against the conveying belt 24, and when the conveying belt 24 is driven by the first transmission shaft 5, the conveying belt 24 drives the rolling members 42 to rotate on the inner shaft 41, so as to perform conveying operation of the conveying belt 24. Gaps 43 are left between the rolling members 42, and one end of the support rod 6 facing the inner shaft 41 is positioned in the gaps 43 and abuts against the inner shaft 41.

Further, the transmission shaft includes a cylindrical section 51 and conical sections 52 disposed at left and right sides of the cylindrical section 51, and a diameter of the conical sections 52 is gradually reduced from an inner side of the transmission shaft to an outer side thereof. As shown in fig. 2 and 5, the same first transmission shaft 5 is shared by the front mounting plate 2, so that two conveyor belts 24 are sleeved on the single first transmission shaft 5 in this embodiment, and the cylindrical section 51 and the conical section 52 are provided at positions where the conveyor belts 24 are sleeved. The conical section 52 is used for fine adjustment of the conveyor belt 24, the conveyor belt 24 is normally located at the cylindrical section 51, and the conveyor belt 24 should be in a non-offset state when the second transmission shaft 4 is not bent; after the second transmission shaft 4 is bent, in order to compensate the deviation of the conveying belt 24 caused by the bending of the second transmission shaft 4, a user can adjust the position of the conveying belt 24 on the first transmission shaft 5 to move the conveying belt 24 towards the side conical section 52, so as to compensate the deviation problem of the conveying belt 24 caused by the bending of the second transmission shaft 4; the adjustment mode of the conical section 52 can be used in cooperation with the adjustment at the tensioning wheel 71, so as to improve the adjustment precision and enable the belt to be in a non-offset state.

It should be noted that the positions of the first transmission shaft 5 and the second transmission shaft 4 in this embodiment may be switched, or the two ends of the conveying table 23 are both the same first transmission shaft 5 or the same second transmission shaft 4, and the specific structure is determined according to the structural layout in the baler.
