[0030] Specific Implementation Method Two: Combining Figures 1 to 9 This embodiment describes a dust cover 3 comprising a dust cover body 3-1 and a docking shaft 3-2. The dust cover body 3-1 is coaxially arranged at the upper opening of the material cylinder 6, and the docking shaft 3-2 is coaxially arranged at the center of the top of the dust cover body 3-1. This arrangement allows the docking shaft 3-2 to cooperate with the dust cover docking mechanism 5-2, thereby enabling the dust cover body 3-1 to be laterally moved out. Other components and connections are the same as in specific embodiment one.

[0031] Specific implementation method three: Combining Figures 1 to 9 In this embodiment, the docking shaft 3-2 includes a connecting shaft section 3-3 and an anti-detachment cap 3-4. The connecting shaft section 3-3 is vertically positioned directly above the center of the dust cover body 3-1. The lower end of the connecting shaft section 3-3 is fixedly connected to the dust cover body 3-1, and the anti-detachment cap 3-4 is coaxially arranged at the upper end of the dust cover body 3-1. This configuration, with the larger diameter anti-detachment cap 3-4 at the end of the connecting shaft section 3-3, prevents the dust cover 3 from detaching from the locking plate 5-4. Other components and connections are the same as in specific embodiments one or two.

[0032] Specific implementation method four: Combination Figures 1 to 9This embodiment describes a dust cover docking mechanism 5-2 that includes a swing rod 5-3 and a locking plate 5-4. The swing rod 5-3 is horizontally positioned above the extension cylinder 5-1. One end of the swing rod 5-3 is connected to the movable end of the extension cylinder 5-1, and the other end is connected to the horizontally positioned locking plate 5-4. This configuration allows the locking plate 5-4 to engage with the docking shaft 3-2, thereby enabling the dust cover body 3-1 to be horizontally moved out via the docking shaft 3-2. Other components and connections are the same as in specific embodiments one, two, or three.

[0033] Specific Implementation Method Five: Combining Figures 1 to 9 In this embodiment, the locking plate 5-4 has a center-mounted docking shaft hole 5-4-1. The side of the locking plate 5-4 has a tapered opening 5-4-2 that penetrates the side of the locking plate 5-4 and the docking shaft hole 5-4-1. The diameter of the docking shaft 3-2 matches the diameter of the docking shaft hole 5-4-1 of the locking plate 5-4. The anti-detachment cap 3-4 is a circular plate structure, and the diameter of the docking shaft hole 5-4-1 of the locking plate 5-4 is smaller than the diameter of the anti-detachment cap 3-4. This configuration allows the docking shaft hole 5-4-1 of the locking plate 5-4 to match the connecting shaft section 3-3 of the docking shaft 3-2. The tapered opening 5-4-2 on the side of the locking plate 5-4 serves as a guide during docking, facilitating smooth docking between the docking shaft 3-2 and the docking shaft hole 5-4-1. The larger-diameter anti-detachment cap 3-4 at the end of the connecting shaft section 3-3 prevents the dust cover 3 from detaching from the locking plate 5-4. Other components and connections are the same as in specific embodiments one, two, three, or four.

[0034] Specific Implementation Method Six: Combination Figures 1 to 9 This embodiment describes a dust cover docking mechanism 5-2 that further includes a telescopic rod 5-5 and a first locking screw 5-6. The swing rod 5-3 is a circular tubular structure, with the telescopic rod 5-5 nested within its inner hole. A vertically arranged threaded sleeve is connected to the side of the swing rod 5-3, and the inner hole of the threaded sleeve is vertically connected to the inner hole of the swing rod 5-3. One end of the first locking screw 5-6 is screwed into the threaded sleeve and abuts against the side of the telescopic rod 5-5. This design makes the dust cover docking mechanism 5-2 a telescopic structure, facilitating adjustment of the distance between the docking shaft hole 5-4-1 of the locking plate 5-4 and the docking shaft 3-2 of the dust cover 3, thereby adapting to different sizes and models of the material cylinder 6 and improving the equipment's versatility. Other components and connections are the same as in specific embodiments one, two, three, four, or five.

Other components and connections are the same as in specific embodiments one, two, three, four, five, or six.

[0036] In this embodiment, the column 1 is a rod-shaped structure with a square cross-section, and the lifting mechanism 4-6 is a square sleeve structure. The lifting mechanism 4-6 is slidably engaged with the column 1, and the lifting mechanism 4-6 drives the material discharge and dust removal mechanism 4-1 to rise and fall under the action of the lifting mechanism.

[0037] Specific implementation method eight: Combination Figures 1 to 9 This embodiment describes a lifting frame 4-5 comprising a T-shaped frame 4-5-1, two round core tubes 4-5-2, two round sleeves 4-5-3, four second locking screws 4-5-4, and four cover connecting plates 4-5-5. One end of the T-shaped frame 4-5-1 is connected to the lifting mechanism 4-6, and the other end of the T-shaped frame 4-5-1 is connected to two horizontally arranged round core tubes 4-5-2. Round sleeves 4-5-3 are fitted onto the round core tubes 4-5-2. Two vertically penetrating threaded holes are opened at both ends of the side wall of the round sleeves 4-5-3.

Other components and connections are the same as in specific embodiments one, two, three, four, five, six, seven, or eight.

[0039] Working principle

[0040] Combination Figures 1 to 9 The working principle of the automatic dust cover loading and unloading device for a material cylinder according to this utility model is as follows: First, an AGV trolley transports a material cylinder 6 with a dust cover 3 to a material cylinder positioning seat 2. The material cylinder 6 is positioned by four guide plates 2-1 on the material cylinder positioning seat 2. At the same time, the material discharge and dust removal mechanism 4-1 is raised to a high position under the action of a lifting cylinder to prepare for cover removal. Then, the dust cover docking mechanism 5-2 rotates to the position of the dust cover 3 under the action of a swing cylinder 5-1. At the same time, the docking shaft hole 5-4-1 on the locking plate 5-4 in the dust cover docking mechanism 5-2 docks with the docking shaft 3-2 on the dust cover 3. Under the action of the swing cylinder 5-1, the dust cover docking mechanism 5-2 drives the dust cover 3 to lift upward, so that the dust cover 3 is detached from the material cylinder 6. At the same time, the anti-detachment cap 3-4 with a large diameter set at the end of the connecting shaft section 3-3 can prevent the dust cover 3 from detaching from the locking plate 5-4. Furthermore, under the action of the swing cylinder 5-1, the dust cover 3 is swung out horizontally, disengaging from the lowering position of the material discharge and dust removal mechanism 4-1. Finally, after the dust cover 3 is swung out horizontally from the material cylinder 6 under the action of the swing cylinder 5-1, the material discharge and dust removal mechanism 4-1 begins to descend under the action of the lifting cylinder, descending to the docking position to begin loading the material cylinder.

[0041] Preparation - removing the lid - removing the lid - unloading constitutes one cycle.
