Figure 1 It is a structural schematic diagram of the opening and closing cover device provided by the utility model; Figure 2 This is one of the principle diagrams of the clamping drive component of the cover opening and closing device provided by the utility model; Figure 3 This is the second principle diagram of the clamping drive component of the cover opening and closing device provided by the utility model.

[0053] like Figure 1 As shown, a specific embodiment of the first aspect of the utility model provides a cover opening and closing device. The cover opening and closing device includes a non-metallic clamping block 100, a clamping driving component 200 and a cover rotating component 300;

[0054] The non-metallic clamping block 100 is used to clamp the bottle body 10. The clamping driving component 200 is connected to the non-metallic clamping block 100 and is used to drive the non-metallic clamping block 100 to clamp or loosen the bottle body 10. The capping component 300 is used to clamp the bottle cap 20 to open or close the cap.

[0055] In this embodiment, a non-metallic clamping block 100 is provided, and the non-metallic clamping block 100 is used to clamp the bottle body 10. When the bottle body 10 and the non-metallic clamping block 100 undergo relative movement, compared with the metal clamping block, the non-metallic clamping block 100 of this embodiment can reduce the friction damage to the bottle body 10 and reduce the degree of damage to the bottle body 10, thereby solving the problem in the prior art that the coal bottle will be seriously damaged during the opening and closing process of the cap opening machine, thereby reducing the service life of the coal bottle.

[0056] In some embodiments, the non-metallic clamping block 100 includes a plastic clamping block, a rubber clamping block, or a silicone clamping block.

[0057] In some embodiments, the capping component 300 includes a clamping jaw 310 and a capping driving assembly 320;

[0058] The clamping jaw 310 is used to clamp the bottle cap 20; the capping drive assembly 320 is connected to the clamping jaw 310 and is used to drive the clamping jaw 310 to rotate to open or close the cap. When opening or closing the cap, the clamping jaw 310 clamps the bottle cap 20, and the capping drive assembly 320 drives the clamping jaw 310 to rotate to open or close the cap.

[0059] Optionally, the clamping jaw 310 is a non-metallic clamping jaw 310 to reduce the wear degree of the bottle cap 20.

[0060] Optionally, the capping drive assembly 320 includes but is not limited to a motor drive.

[0061] In some embodiments, the opening and closing cover device also includes a lifting component 400; the lifting component 400 is connected to the clamp 310, and is used to drive the clamp 310 to move along the height direction of the bottle body 10, so that the height of the clamp 310 adapts to the height of the bottle cap 20, so that the opening and closing cover device is suitable for bottles of different heights, thereby expanding the application range of the opening and closing cover device.

[0062] Optionally, the lifting component 400 includes but is not limited to an electric telescopic rod or a wheel assembly.

[0063] Specifically, the clamping jaw 310 is connected to the transmission belt of the pulley assembly, and the pulley assembly is driven by the motor to rotate forward so that the clamping jaw 310 rises along the bottle body 10. The pulley assembly is driven by the motor to reverse so that the clamping jaw 310 descends along the bottle body 10.

[0064] In some embodiments, the clamping drive component 200 includes a motor drive assembly; the motor drive assembly includes a motor, and the driving end of the motor is connected to the non-metallic clamping block 100, which is used to drive the non-metallic clamping block 100 to move toward or away from the bottle body 10, so that the non-metallic clamping block 100 clamps or releases the bottle body 10.

[0065] like Figure 2 As shown, in some embodiments, the clamping drive component 200 includes a first clamping drive assembly 210; the first clamping drive assembly 210 includes a first cylinder 215, a first reversing valve 211, a first on-off valve 212, a first pressure reducing valve 213 and a first check valve 216;

[0066] Among them, the first cylinder body 215 has a first driving rod, and the first driving rod is connected to the non-metallic clamping block 100; the first interface of the first reversing valve 211 is used for fluid entry, and the second interface of the first reversing valve 211 is used for discharging fluid; the second working interface of the first reversing valve 211 is connected to the rodless chamber of the first cylinder body 215; the inlet of the first on-off valve 212 is connected to the first working interface of the first reversing valve 211; the outlet of the first on-off valve 212 is connected to the rod chamber of the first cylinder body 215; the inlet of the first pressure reducing valve 213 is connected to the first working interface of the first reversing valve 211; the inlet of the first one-way valve 216 is connected to the outlet of the first pressure reducing valve 213, and the outlet of the first one-way valve 216 is connected to the rod chamber of the first cylinder body 215.

[0067] When closing the lid, the first on-off valve 212 is disconnected, and the fluid flows in from the first interface of the first reversing valve 211, and then after being decompressed by the first pressure reducing valve 213, it flows into the rod chamber of the first cylinder 215 through the first one-way valve 216; at the same time, the fluid in the rodless chamber of the first cylinder 215 flows out through the second working interface and the second interface of the first reversing valve 211, so that the first driving rod drives the non-metallic clamping block 100 to clamp the bottle body 10. At this time, the set torque required for closing the lid can be set by the first pressure reducing valve 213. In this way, during the process of closing the lid, when the closing torque reaches the set torque, the bottle body 10 and the non-metallic clamping block 100 can produce relative sliding, ensuring that the clamping jaws 310 and the bottle cap 20 will not produce relative movement and wear, thereby protecting the coal bottle.

[0068] When opening the cover, the first on-off valve 212 is connected, and the fluid flows in from the first interface of the first reversing valve 211, and then flows into the rod chamber of the first cylinder 215 through the first on-off valve 212; at the same time, the fluid in the rodless chamber of the first cylinder 215 flows out through the second working interface and the second interface of the first reversing valve 211, so that the first driving rod drives the non-metallic clamping block 100 to clamp the bottle body 10. At this time, because the fluid is not decompressed before entering the rod chamber, the friction torque generated by the non-metallic clamping block 100 and the bottle body 10 is relatively large when the flow rate and pressure of the inflowing fluid remain unchanged, and the friction torque can be made greater than the set torque required for opening the cover by adjusting the fluid flow rate and pressure, thereby ensuring that the bottle cap 20 can be opened smoothly.

[0069] After opening and closing the cover, the first reversing valve 211 is reversed, the first on-off valve 212 is connected, and the fluid flows from the second interface of the first reversing valve 211 into the rodless chamber of the first cylinder 215. The fluid in the rod chamber of the first cylinder 215 passes through the first on-off valve 212 and the first working interface of the first reversing valve 211, and is discharged from the first interface of the first reversing valve 211, so that the non-metallic clamping block 100 loosens the bottle body 10.

[0070] The first one-way valve 216 is provided to prevent the fluid from flowing back toward the first pressure reducing valve 213 and damaging the first pressure reducing valve 213 , thereby protecting the first pressure reducing valve 213 .

[0071] Optionally, the first reversing valve 211 is a two-position four-way solenoid valve.

[0072] Optionally, the first on-off valve 212 is a one-position two-way solenoid valve.

[0073] Optionally, the fluid may be gas or liquid, the gas is preferably air, and the liquid is preferably hydraulic oil.

[0074] In some other embodiments, the outlet of the first on-off valve 212 may be communicated with the rodless chamber of the first cylinder 215 , and the second working interface of the first reversing valve 211 may also be communicated with the rod chamber of the first cylinder 215 .

[0075] In some embodiments, when the fluid is gas, the first clamping drive assembly 210 further includes a quick exhaust valve 214; the air inlet of the quick exhaust valve 214 is connected to the outlet of the first on-off valve 212 and the outlet of the first one-way valve 216. When closing or opening the cover, the gas passes through the quick exhaust valve 214 and enters the rod chamber of the first cylinder 215. After the cover is opened or closed, the gas in the rod chamber of the first cylinder 215 is discharged from the quick exhaust valve 214, so as to achieve the purpose of quickly loosening the bottle body 10.

[0076] In some embodiments, the first clamping drive assembly 210 further includes a first throttle valve 217; two interfaces of the first throttle valve 217 are respectively connected to the rodless chamber of the first cylinder 215 and the second working interface of the first reversing valve 211. The first throttle valve 217 can be provided to control the fluid flow.

[0077] like Figure 3 As shown, in some other embodiments, the clamping drive component 200 further includes a second clamping drive assembly 220; the second clamping drive assembly 220 includes a second cylinder 223, a second reversing valve 221 and a secondary pressure regulating circuit 222;

[0078] Among them, the second cylinder body 223 has a second driving rod, and the second driving rod is connected to the non-metallic clamping block 100; the first interface of the second reversing valve 221 is used for fluid inflow, and the second interface of the second reversing valve 221 is used for fluid discharge, the first working interface of the second reversing valve 221 is connected to the rod chamber of the second cylinder body 223, and the second working interface of the second reversing valve 221 is connected to the rodless chamber of the second cylinder body 223; the inlet of the secondary pressure regulating circuit 222 is connected to the first interface of the second reversing valve 221, and the outlet of the secondary pressure regulating circuit 222 is used for fluid discharge; the secondary pressure regulating circuit 222 has a first position and a second position; the pressure of the secondary pressure regulating circuit 222 in the first position is greater than the pressure in the second position.

[0079] When closing the lid, the secondary pressure regulating circuit 222 is in the second position, and the fluid enters the rod chamber of the second cylinder 223 through the first interface and the first working interface of the second reversing valve 221. At the same time, the fluid in the rodless chamber of the second cylinder 223 is discharged through the second working interface and the second interface of the second reversing valve 221, so that the non-metallic clamping block 100 clamps the bottle body 10. At this time, the pressure of the secondary pressure regulating circuit 222 in the second position is the pressure of the non-metallic clamping block 100 on the bottle body 10, and the friction torque generated is less than the set torque required for closing the lid. In this way, during the closing process, when the closing torque reaches the set torque, the bottle body 10 and the non-metallic clamping block 100 can slide relative to each other, ensuring that the clamping jaws 310 and the bottle cap 20 will not move relative to each other and wear, thereby protecting the coal bottle.

[0080] When opening the cap, the secondary pressure regulating circuit 222 is in the first position, and the fluid enters the rod chamber of the second cylinder 223 through the first interface and the first working interface of the second reversing valve 221, and at the same time, the fluid in the rodless chamber of the second cylinder 223 is discharged through the second working interface and the second interface of the second reversing valve 221, so that the non-metallic clamping block 100 clamps the bottle body 10. At this time, the pressure of the secondary pressure regulating circuit 222 in the first position is the pressure of the non-metallic clamping block 100 on the bottle body 10, and the friction torque generated by it is greater than the set torque required for opening the cap, ensuring that the bottle cap 20 can be opened smoothly.

[0081] After the cover is opened and closed, the second reversing valve 221 is reversed, and the secondary pressure regulating circuit 222 is in the second position, and enters the rod chamber of the second cylinder 223 through the first interface and the first working interface of the second reversing valve 221. At the same time, the fluid in the rodless chamber of the second cylinder 223 is discharged through the second working interface and the second interface of the second reversing valve 221, and the non-metallic clamping block 100 is released.

[0082] Preferably, the fluid entering the second reversing valve 221 is hydraulic oil.

[0083] Specifically, the first interface of the second reversing valve 221 is connected to the oil tank through the hydraulic pump 227 to allow hydraulic pressure to flow in. The second interface of the second reversing valve 221 is connected to the oil tank to supply hydraulic oil back to the oil tank.

[0084] In some embodiments, the secondary pressure regulating circuit 222 includes a relief valve 2221 , a second on-off valve 2222 , and a second pressure reducing valve 2223 ;

[0085] Among them, the inlet of the overflow valve 2221 is connected to the first interface of the second reversing valve 221, and the outlet of the overflow valve 2221 is for fluid discharge; the inlet of the second on-off valve 2222 is connected to the overflow chamber of the overflow valve 2221; the inlet of the second pressure reducing valve 2223 is connected to the outlet of the second on-off valve 2222, and the outlet of the second pressure reducing valve 2223 is for fluid discharge. Specifically, the inlet of the overflow valve 2221 is connected to the first interface of the second reversing valve 221, and the outlet of the overflow valve 2221 is connected to the oil tank; the inlet of the second on-off valve 2222 is connected to the overflow chamber of the overflow valve 2221; the inlet of the second pressure reducing valve 2223 is connected to the outlet of the second on-off valve 2222, and the outlet of the second pressure reducing valve 2223 is connected to the oil tank.

[0086] The set pressure of the second pressure reducing valve 2223 is lower than the pressure of the relief valve 2221. The pressure of the secondary pressure regulating circuit 222 when the second on-off valve 2222 is disconnected is higher than the pressure when the second on-off valve 2222 is connected.

[0087] When closing the lid, the second on-off valve 2222 is connected, and the system pressure is reduced by the overflow valve 2221 and the second pressure reducing valve 2223 for two stages, and the hydraulic oil enters the rod chamber of the second cylinder 223 through the first interface and the first working interface of the second reversing valve 221, and at the same time, the hydraulic oil in the rodless chamber of the second cylinder 223 is discharged through the second working interface and the second interface of the second reversing valve 221, so that the non-metallic clamping block 100 clamps the bottle body 10. At this time, the system pressure is the pressure of the non-metallic clamping block 100 on the bottle body 10, and the friction torque generated by it is less than the set torque required for closing the lid. In this way, during the closing process, when the closing torque reaches the set torque, the bottle body 10 and the non-metallic clamping block 100 can slide relative to each other, ensuring that the clamping jaws 310 and the bottle cap 20 will not produce relative movement and wear, thereby protecting the coal bottle.

[0088] When opening the cover, the second on-off valve 2222 is disconnected, and the system pressure is not reduced through the second pressure reducing valve 2223. Under a relatively high pressure, the hydraulic oil enters the rod chamber of the second cylinder 223 through the first interface and the first working interface of the second reversing valve 221, and at the same time, the fluid in the rodless chamber of the second cylinder 223 is discharged through the second working interface and the second interface of the second reversing valve 221, so that the non-metallic clamping block 100 clamps the bottle body 10. At this time, the system pressure is the pressure of the non-metallic clamping block 100 on the bottle body 10, and the friction torque generated by the non-metallic clamping block 100 is greater than the set torque required for opening the cover, ensuring that the bottle cap 20 can be opened smoothly.

[0089] After the cover is opened and closed, the second on-off valve 2222 is disconnected, the second reversing valve 221 is reversed, and the fluid enters the rod chamber of the second cylinder 223 through the first interface and the first working interface of the second reversing valve 221. At the same time, the fluid in the rodless chamber of the second cylinder 223 is discharged through the second working interface and the second interface of the second reversing valve 221, thereby releasing the non-metallic clamping block 100.

[0090] In some embodiments, the first working interface of the second reversing valve 221 is communicated with the rod chamber of the second cylinder 223 through the second throttle valve 224, and the second working interface of the second reversing valve 221 is communicated with the rodless chamber of the second cylinder 223 through the third throttle valve 225. The second throttle valve 224 and the third throttle valve 225 can adjust the flow rate of the fluid.

[0091] In some other embodiments, the first working interface of the second reversing valve 221 can be connected to the rodless chamber of the second cylinder body 223 through the second throttle valve 224, and the second working interface of the second reversing valve 221 can be connected to the rod chamber of the second cylinder body 223 through the third throttle valve 225.

[0092] In some embodiments, the second clamping drive assembly 220 further includes a pressure sensor 226, which is disposed at the first interface of the second reversing valve 221 and is used to detect real-time pressure so that the user can observe the real-time pressure of the system.

[0093] In some embodiments, the second clamping drive assembly 220 further includes a controller and an alarm;

[0094] The controller is electrically connected to the pressure sensor 226; the alarm is electrically connected to the controller; the controller outputs an alarm control instruction according to the real-time pressure to control the alarm to sound an alarm.
