Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The specific embodiments of this utility model will now be described with reference to the accompanying drawings:

[0024] like Figures 1-5 As shown, a can opening sealing mechanism includes a can body 1, with a can opening 13 on one side and a discharge pipe 12 on the other side. Material is added to the can body 1 through the can opening 13 and discharged from the can body 1 through the discharge pipe 12. A sealing plate mechanism 2 is provided on the can body 1 corresponding to the can opening 13. The sealing plate mechanism 2 includes a cover plate 21 and a driving assembly. The cover plate 21 is located above the can opening 13 and is slidably connected to the can body 1. Supports 15, fixedly connected to the can body 1, are provided on both sides of the can opening 13. A track 151 is provided on the top surface of the support 15. A movable support 23, fixedly connected to the cover plate 21, is provided on both sides of the movable support 23, with multiple rollers 231 cooperating with the track 151. The cover plate 21 moves along the track 151 via the rollers 231.

[0025] A limiting plate 14 is provided on the side of the can opening 13 away from the drive assembly, and a buffer pad 141 is provided on the side of the limiting plate 14 near the can opening 13. The limiting plate 14 facilitates positioning the cover plate 21 directly above the can opening 13 when the can opening 13 is closed; the buffer pad 141 prevents rigid collision between the cover plate 21 and the limiting plate 14, reducing component damage. A protruding rib 131 is provided on the can opening 13 along the moving direction of the cover plate 21, and a groove 212 is provided on the cover plate 21 to engage with the protruding rib 131. The engagement of the protruding rib 131 and the groove 212 allows for quick determination of the relative position of the cover plate 21 and the can opening 13, improving assembly efficiency.

[0026] A removable wedge gasket 16 is provided on the can opening 13. As the cover plate 21 covers the can opening 13, the wedge gasket 16 adheres to the cover plate 21 and its thickness gradually increases. The wedge gasket 16 improves the sealing performance when the cover plate 21 closes the can opening 13, preventing dust from escaping from the can opening 13. The edge of the cover plate 21 near the wedge gasket 16 has a rounded corner 213. The rounded corner 213 prevents the edge of the cover plate 21 from impacting and damaging the wedge gasket 16. The side of the wedge gasket 16 near the can opening 13 has multiple evenly spaced positioning pins 161, and the can opening 13 has positioning holes that mate with the positioning pins 161. The wedge gasket 16 is generally made of rubber, and its elasticity may decrease or even break with increased use. The removable wedge gasket 16 facilitates quick replacement with a new one, thereby ensuring the sealing performance of the cover plate 21. An elastic pad 152 is provided on the inner top surface of the track 151, and the elastic pad 152 rolls in contact with the roller 231. During the process of the cover plate 21 covering the can opening 13, the entire sealing plate mechanism 2 is subjected to an upward force due to the action of the wedge pad 16. Under this force, the interaction force between the roller 231 and the inner top surface of the track 151 is relatively large, which may cause significant damage to the inner top surface of the track 151 and the rotating shaft of the roller 231. The presence of the elastic pad 152 can ensure that the roller 231 is provided with an upward offset clearance, which can ensure that the roller 231 rolls normally along the track 151 and reduce damage to the roller 231 or the track 151.

[0027] A drive assembly fixedly connected to the tank body 1 is provided on one side of the cover plate 21. The drive assembly includes multiple cylinders 22, and multiple fixing blocks 211 are symmetrically distributed on the cover plate 21. The telescopic end of the cylinder 22 is detachably connected to the fixing block 211 by fasteners, and the other end is detachably connected to the fixing post 17 on the tank body 1 by fasteners. By uniformly applying external force to the cover plate 21 through multiple cylinders 22, the cover plate 21 is used to close or open the tank opening 13, saving manpower and reducing the probability of operators being exposed to dust pollution. The detachable cylinders 22 facilitate maintenance or replacement.

[0028] The working principle of this utility model is as follows: the cylinder 22 drives the cover plate 21 to move along the track 151. When it is necessary to open the can opening 13, the cover plate 21 moves away from the top of the can opening 13 along the track 151. When it is necessary to close the can opening 13, the cover plate 21 moves along the track 151 to directly above the can opening 13.
