[0037] See also Figures 1 to 5The material cover opening and closing device provided by the present invention is now described. A material cover opening and closing device includes a support beam 1, a connecting member 2, an elastic energy absorbing component 3, an annular seal 4, an annular retaining ring 5, and a driving mechanism 6; the support beam 1 is used to be installed on a working frame 7 and is used to be set on one side of the tank body 71; the support beam 1 is provided with a mounting seat 11 and a rotating shaft 12 rotatably connected to the mounting seat 11; one end of the connecting member 2 is fixedly connected to the rotating shaft 12, and the other end extends outward in a direction away from the rotating shaft 12; the material cover 72 is used to be fixedly installed on the other end of the connecting member 2; the number of the elastic energy absorbing components 3 is two , respectively installed on both sides of the support beam 1; the elastic energy absorbing components 3 are arranged vertically, and the two elastic energy absorbing components 3 are respectively used to connect with the connecting parts 2 in the two states before and after flipping; the annular seal 4 is used to be installed on the outer upper end of the tank body 71; the inner ring of the annular seal 4 is provided with an annular groove 41; the annular retaining ring 5 is used to be fixedly installed on the lower end surface of the material cover 72, and the annular retaining ring 5 is installed in conjunction with the annular groove 41; the driving mechanism 6 is connected to the rotating shaft 12 for driving the rotating shaft 12, the connecting part 2 and the material cover 72 to flip.

[0038] Compared with the prior art, the material cover opening and closing device provided by the present invention is as follows: before use, a support beam 1 is set on the working frame 7, and a mounting seat 11, a rotating shaft 12, and a driving mechanism 6 are set on the support beam 1, and then a connecting piece 2 is installed on the rotating shaft 12, and the material cover 72 is installed on the connecting piece 2; then, elastic energy absorbing components 3 are installed on both sides of the support beam 1, and an annular seal 4 is installed on the upper part of the outer side of the tank body 71, and an annular groove 41 is provided on the side of the annular seal 4 close to the outer side of the tank body 71; when it is necessary to close the material cover 72, the driving mechanism 6 is started to control the rotating shaft 1 2 rotates on the mounting base 11, thereby driving the connecting member 2 and the material cover 72 to rotate toward the tank body 71. As the material cover 72 approaches the tank body 71, the connecting member 2 contacts the elastic energy-absorbing component 3. The characteristics of the elastic energy-absorbing component 3 absorb the kinetic energy of the connecting member 2 and the material cover 72, thereby reducing the rotation speed of the material cover 72, the impact force of the material cover 72 on the upper end of the tank body 71, and reducing noise. The annular retaining ring 5 at the lower end of the material cover 72 is installed in conjunction with the annular groove 41 of the annular sealing member 4 on the outside of the tank body 71, forming a sealed connection between the material cover 72 and the outside of the tank body 71. Similarly, when the material cover 72 needs to be opened, the connecting member 2 and the material cover 72 rotate in a direction away from the tank body 71. When the material cover 72 is in a horizontal state, the material cover 72 contacts another elastic energy-absorbing component 3, thereby effectively absorbing kinetic energy and impact force, without generating loud noise or deformation of the material cover 72 itself.

[0039] The driving mechanism 6 includes a cylinder, a connecting rod and a cam, or the driving mechanism 6 includes a motor, a reducer, a coupling, etc.

[0040] See also Figure 1 、 Figure 2 and Figure 4 The cam 33 is pressed against the top of the cam 33 and the cam 33 is pressed against the top of the cam 33 to release the cam 33. The cam 33 is pressed against the top of the cam 33 and the cam 33 is pressed against the top of the cam 33 to release the cam 33. The extrusion block 33 is slidably connected to the guide cylinder 31, with its lower end exerting pressure on the elastic member 32. The trigger rod 34, on the other hand, is inserted into the guide cylinder 31, with its lower end fixedly connected to the extrusion block 33 and its upper end positioned above the guide cylinder 31. Specifically, when the connector 2 and the cover 72 are enclosed on the can 71, the lower end surface of the connector 2 first contacts the upper end of the trigger rod 34 during rotation, before the cover 72 collides with the upper end of the can 71. This causes the trigger rod 34 and the extrusion block 33 to move downward, compressing the elastic member 32. The elastic member 32 absorbs and buffers the kinetic energy from the connector 2 and the cover 72, thereby significantly slowing the rotation of the cover 72 and ultimately allowing the cover 72 to more gently contact the can 71. Preferably, the elastic member 32 is a spring.

[0041] See also Figure 1 and Figure 2 As a specific embodiment of the material cover opening and closing device provided by the present invention, a force rod 21 is provided at the lower end of the connecting member 2, perpendicular to the connecting member 2. The lower end of the force rod 21 is connected to the upper end of the trigger rod 34. The force rod 21 is perpendicular to the connecting member 2 and is disposed on the lower end surface of the connecting member 2. During the downward rotation of the connecting member 2, the force rod 21 contacts the trigger rod 34, which in turn acts on the elastic member 32 to absorb kinetic energy and slow the rotation of the connecting member 2 and the material cover 72. The provision of the force rod 21 advances the time at which the connecting member 2 acts on the elastic energy-absorbing assembly 3, thereby making the speed reduction during the latter part of the movement of the material cover 72 more uniform and smooth.

[0042] See also Figure 1 and Figure 2As a specific embodiment of the material cover opening and closing device provided by the present invention, a docking plate 22 is provided at the lower end of the force rod 21 and the upper end of the trigger rod 34; a docking plate 22 is provided at the lower end of the force rod 21 and the upper end of the trigger rod 34, so that when the force rod 21 acts on the trigger rod 34, the contact area between the force rod 21 and the trigger rod 34 is increased with the help of the docking plate 22, and the docking is more accurate.

[0043] See also Figure 1 、 Figure 4 and Figure 5 As a specific embodiment of the material cover opening and closing device provided by the present invention, the cross-sectional area of ​​the docking plate 22 located on the side of the support beam 1 away from the tank body 71 is larger than the cross-sectional area of ​​the docking plate 22 located between the support beam 1 and the tank body 71; the elastic energy absorbing component 3 located on the side of the support beam 1 away from the tank body 71 is used to connect with the material cover 72 when the tank body 71 is in the open state. At this time, the material cover 72 directly acts on the docking plate 22 of the elastic energy absorbing component 3. The cross-sectional area of ​​the docking plate 22 at this position is set to be larger than the docking plate 22 on the other elastic energy absorbing component 3, so that the material cover 72 is stable in this state.

[0044] See also Figure 5 As a specific embodiment of the material cover opening and closing device provided by the utility model, the number of guide cylinders 31 is multiple and evenly spaced; each guide cylinder 31 is provided with an elastic member 32, an extrusion block 33, and a trigger rod 34. With the help of multiple guide cylinders 31, the connecting member 2 can act on multiple trigger rods 34 at the same time, further slowing down the rotation speed of the material cover 72 when it contacts the tank body 71, so that the material cover 72 will not produce a strong collision with the tank body 71, and the noise is also relatively small.

[0045] See also Figure 1 and Figure 5 As a specific embodiment of the lid opening and closing device provided by the present invention, the connecting member 2 is a plate-like structure, and its other end is provided with an arcuate concave surface 23 for mating with the outer side of the lid 72. The plate-like structure of the connecting member 2 has a large width, which increases the connecting member 2's ability to transmit torque, allowing the rotating shaft 12 to smoothly and smoothly drive the lid 72 into action. The use of a plate-like structure as the connecting member 2 also increases the connection length between the connecting member 2 and the rotating shaft 12. The arcuate concave surface 23 at the other end of the connecting member 2 is adapted to the outer side of the tank body 71, further ensuring a more secure connection between the connecting member 2 and the tank body 71.

[0046] See also Figure 5 As a specific embodiment of the material cover opening and closing device provided by the present invention, a plurality of process holes 24 are provided on the connecting piece 2; the provision of the process holes 24 can effectively reduce the weight of the connecting piece 2 and also make the connecting piece 2 have a good appearance.

The fixing portion 25 is arranged perpendicular to the connector 2 and is fixedly connected to the rotating shaft 12. The fixing portion 25 is formed by bending one end of the connector 2 downward and is perpendicular to the connector 2. The end of the fixing portion 25 away from the connector 2 is fixedly connected to the outer surface of the rotating shaft 12, creating a certain radial distance between the rotating shaft 12 and the connector 2. This allows the connector 2 and the lid 72 to move toward or away from the can body 71 more smoothly as the rotating shaft 12 rotates. The fixing portion 25 and the connector 2 are integrally formed.
