[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example

[0032] like Figure 1-7 As shown, an embodiment of the present invention provides a rotary waste removal shaft device, including a waste removal shaft 1. The two ends of the waste removal shaft 1 are movably connected to connecting plates 2. One of the connecting plates 2 is provided with a servo motor 5 for driving the waste removal shaft 1 to rotate. The end of the connecting plate 2 away from the waste removal shaft 1 is also connected to an adjustment mechanism 3 for controlling the lifting and lowering of the waste removal shaft 1. The waste removal shaft 1 is movably installed inside the waste removal machine 4 through the connecting plates 2 on both sides and the adjustment mechanism 3.

[0033] like Figure 1-5 As shown, in some embodiments, the connecting plate 2 is provided with a bearing seat 201, and the two ends of the waste removal shaft 1 are rotatably connected to the two connecting plates 2 through the bearing seat 201 respectively.

[0034] The bearing housing 201 improves the rotational stability of the waste removal shaft 1, reduces axial movement, and facilitates disassembly and maintenance, thus extending the service life of the equipment.

[0035] like Figure 1-5As shown, in some embodiments, one side of the connecting plate 2 is provided with a cover 6 for mounting the servo motor 5, and one end of the waste removal shaft 1 extends through the bearing seat 201 into the interior of the cover 6 and is provided with a driven gear 101.

[0036] The gland 6 has a compact structure and good sealing performance, preventing external impurities from entering the gear transmission area and ensuring the reliability of power transmission.

[0037] like Figure 1-5 As shown, in some embodiments, a planetary reducer 7 is provided on one side of the servo motor 5 and is connected to it for transmission. The output end of the planetary reducer 7 extends into the inside of the pressure cover 6 and is provided with a drive gear 701. The drive gear 701 and the driven gear 101 are connected by a synchronous belt 8 for transmission.

[0038] The planetary reducer 7 and synchronous belt 8 combined transmission method has both high torque output and low noise characteristics, which can adapt to the intermittent load requirements of waste cleaning operation. The starter servo motor 5 drives the drive gear 701 to rotate through the planetary reducer 7. The drive gear 701 drives the driven gear 101 to rotate through the synchronous belt 8. The driven gear 101 drives the waste cleaning shaft 1 to rotate. The waste cleaning shaft 1 uses rotational force to bounce the waste paper fragments on the carton away.

[0039] like Figure 1-5 As shown, in some embodiments, the adjustment mechanism 3 includes a slider 301, a linear guide rail 302, and a cylinder 303. The linear guide rail 302 is fixedly installed inside the waste cleaning machine 4. A slider 301 is provided on one side of the connecting plate 2. The connecting plate 2 is slidably connected to the linear guide rail 302 through the slider 301.

[0040] The linear guide 302 and the slider 301 work together to achieve precise vertical lifting and lowering of the waste removal shaft 1, avoiding jamming caused by off-center load and improving adjustment accuracy.

[0041] like Figure 1-5 As shown, in some embodiments, the connecting plate 2 is provided with a cylinder front seat 305 on the side away from the slider 301, which is movably connected to the output end of the cylinder 303 through a Y-type connector 304.

[0042] Y-type connector 304 allows cylinder 303 to adapt to small angular deviations during push-pull processes, reducing the risk of wear on connectors and improving the durability of the mechanism.

[0043] like Figure 1-5 As shown, in some embodiments, the bottom of the cylinder 303 is movably connected to a fine-tuning mechanism 9.

[0044] The initial position of cylinder 303 can be calibrated by fine-tuning mechanism 9 to compensate for installation errors and ensure the repeatability of the lifting stroke of waste removal shaft 1.

[0045] like Figure 1-5 As shown, in some embodiments, the fine-tuning mechanism 9 includes an adjustment bracket 901, an adjustment screw 902 is movably disposed inside the adjustment bracket 901, and an adjustment handle 903 is disposed at the bottom of the adjustment screw 902.

[0046] The adjusting screw 902 has a simple and reliable structure. It can be finely adjusted by manual rotation with high precision, making it easy to quickly adapt to different working conditions on site.

[0047] like Figure 1-5 As shown, in some embodiments, the top of the adjusting screw 902 passes through a section of the adjusting bracket 901 and is threaded with an adjusting block 904, one side of which is movably hinged to the bottom of the cylinder 303.

[0048] The combined design of the adjusting block 904 and the cylinder 303 hinge structure ensures the adjustment accuracy while avoiding rigid interference when the cylinder 303 is under force, thus further ensuring the stability of the cylinder 303.

[0049] like Figure 1-5 As shown, in some embodiments, the number of linear guide rails 302 is not less than one, and guide rail baffles 306 are provided at the top and bottom of the linear guide rails 302.

[0050] The top and bottom of two adjacent linear guides 302 are connected to a guide baffle 306. This design further ensures the stability of the linear guides 302, and the guide baffle 306 blocks the ends of the linear guides 302, preventing the slider 301 from slipping directly off the linear guides 302.

[0051] When using it, please refer to Figure 6 Before starting the equipment, the waste removal shaft 1 remains in a ready-to-rotate state, and cylinder 303 remains in a ready-to-rise state. After starting the equipment, refer to... Figure 7 The cylinder 303 is started to lift the connecting plate 2 and the waste removal shaft 1. The servo motor 5 is started to drive the waste removal shaft 1 to rotate. The waste removal shaft 1 uses rotational force to bounce away the waste paper fragments. After cleaning is completed, the cylinder 303 and the waste removal shaft 1 are reset to the state before starting.

[0052] In summary, by using servo motor 5 and lifting adjustment mechanism 3, the traditional waste removal method is changed. Its high-speed rotating waste removal shaft 1 can effectively eject stubborn paper scraps remaining on the surface and edges of the carton. Combined with the adaptive height adjustment function, it ensures the cleaning effect of cartons of different thicknesses. The overall structure operates stably and with low noise. The bearing seat 201 supports and greatly extends the equipment life, reduces the need for manual intervention, and enables a breakthrough improvement in the waste removal efficiency and product qualification rate of the production line, while reducing the scrap rate and production costs.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
