DETAILED DESCRIPTION

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] like Figure 1-3 As shown, this embodiment provides a same-direction bag sorting mechanism, including a base 1, a lifting mechanism, a rotating mechanism, and a straw 2. The lifting mechanism and the rotating mechanism are arranged on the base 1. The straw 2 is telescopically connected to the base 1. The output end of the lifting mechanism is axially limited and rotationally connected to the straw 2. The output end of the rotating mechanism is circumferentially limited and slidingly connected to the straw 2. The working principle of this bag sorting mechanism is: when the bagged material reaches the bottom of this mechanism and the material direction needs to be adjusted, the lifting mechanism is actuated to make the straw 2 approach the material surface downward, and the straw uses a vacuum pump and other equipment to generate suction to suck the material; then the rotating mechanism drives the straw to rotate 180 degrees, thereby changing the head and tail direction of the material; finally, the straw releases the material, and then the lifting mechanism drives the straw to reset upward. In order to improve the adsorption stability and avoid damage to the material packaging caused by the straw, an elastic suction nozzle 5 is provided at the lower end of the straw 2. The elastic suction nozzle is easier to adapt to the surface shape of the material to ensure the adsorption effect, and the elastic material is not easy to damage the material packaging.

[0026] Specifically, the lifting mechanism includes a support 31, a lifting motor 32, a screw 33, a nut 34, and a lifting plate 35. The screw 33 is rotatably connected to the support 31 in an axially limited manner. The nut 34 is provided on the lifting plate 35. The screw 33 is threadedly connected to the nut 34. The lifting motor 32 is transmission-connected to the screw 33. The lifting plate 35 is rotatably connected to the straw 2 in an axially limited manner. Thus, the lifting motor 32 drives the screw 33 to rotate, and the screw 33 drives the lifting plate 35 to rise and fall by cooperating with the thread of the nut 34, and the straw 2 rises and falls synchronously with the rise and fall of the lifting plate 35. The specific connection method between the lifting plate 35 and the straw 2 can be: the lifting plate 35 is provided with a first bearing 36, and the straw 2 is provided with a first limiting hoop 361 on the upper and lower sides of the first bearing 36, and the first limiting hoop 361 can be installed and positioned by opening an annular groove on the straw 2, so that the straw 2 cannot slide up and down relative to the lifting plate 35, and does not affect the rotation of the straw 2. Similarly, the screw 33 is connected to the support 31 in a similar manner, that is, the support 31 is provided with a second bearing 37, and the screw 33 is provided with a second limiting hoop on the upper and lower sides of the second bearing 37.

[0027] In order to ensure the lifting range as much as possible without increasing the height of the entire mechanism, the support 31 includes a support plate 311 and a plurality of legs 312. The lifting motor 32 is arranged above the support plate 311, and the output end of the lifting motor 32 is transmission-connected with the screw rod 33 below the support plate 311. Thus, the transmission connection end of the lifting motor and the screw rod is at the lower end, leaving enough space for the lifting and lowering of the upper lifting plate.

[0028] The rotating mechanism includes a rotating motor 41, a driving synchronous pulley 42, a driven synchronous pulley 43, and a synchronous belt. The driving synchronous pulley 42 is arranged at the output end of the rotating motor 41, the driven synchronous pulley 43 is slidably connected to the straw 2 in a circumferentially limited manner, and the driven synchronous pulley 43 is rotationally connected to the base 1 in an axially limited manner. The method of using a motor, a synchronous pulley and a synchronous belt to transmit the power is relatively conventional. However, since the rotating motor 41 needs to be fixedly arranged on the base 1, and the straw 2 needs to be raised and lowered, the driven synchronous pulley 43 arranged on the straw 2 needs to slide up and down relative to the straw 2, and the two need to rotate synchronously. For this reason, a third bearing 44 is arranged on the base 1, and the driven synchronous pulley 43 is provided with a third limiting hoop 441 on the upper and lower sides of the third bearing 44, so as to prevent the driven synchronous pulley from moving up and down without affecting the rotation of the driven synchronous pulley, thereby stably cooperating with the driving synchronous pulley at the output end of the rotating motor. At the same time, a sliding limit groove 21 is provided on the side of the straw 2 along its axial direction, and a circumferential limit block is provided between the driven synchronous pulley 43 and the sliding limit groove 21, so that the straw 2 can slide up and down along the driven synchronous pulley 43, and the two can rotate synchronously.

[0029] In addition, the output end of the rotating motor 41 is arranged below the base 1 to leave space for other components on the base to avoid interference with each other.

[0030] The above is only a preferred specific implementation of the utility model, which is a realization method based on the overall concept of the utility model, and the protection scope of the utility model is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
