DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0025] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0026] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown in the figure, in the embodiment of the utility model, a hopper docking frame with automatic valve opening comprises a hopper 1, a docking frame 2 and a control unit. The upper end of the hopper 1 has a feed port, and the feed port is provided with a control valve 11. The control valve 11 has an open state and a closed state.

[0028] An upper automatic docking assembly for docking with the hopper 1 is fixed on the upper end of the docking frame 2, and the automatic docking assembly includes a docking barrel 41 and a lifting drive mechanism 42. The lifting drive mechanism 42 is fixed on the docking frame 2, and its driving end is fixed on the docking barrel 41 for driving the docking barrel 41 to rise and fall. An automatic valve opening assembly for controlling the opening and closing of the control valve 11 is fixed on one side of the docking frame 2. A first in-place detection assembly 31 for detecting the in-place status of the hopper 1 and a second in-place detection assembly for detecting the in-place status of the docking barrel 41 are provided on the docking frame 2.

[0029] It also includes a control system, which is electrically connected to the first in-place detection component 31, the lifting drive mechanism 42, the second in-place detection component, and the automatic valve opening component.

[0030] When there is a need to connect materials, the hopper is pushed into the docking frame, and the first in-place detection component on the docking frame detects the in-place signal of the hopper and sends it to the control system. The control system sends a signal to the lifting drive mechanism, and the lifting drive mechanism drives the docking barrel to descend and dock with the hopper, and feeds back the in-place signal of the docking barrel to the control system, and the automatic valve opening component switches the control valve to the open state, thereby realizing the material dropping. Among them, the control system can adopt the PLC control system commonly used in automated production equipment or other automated control systems that can realize the above functions, and the in-place detection component can specifically use an infrared detector for in-place detection; the lifting drive mechanism is specifically a lifting cylinder.

[0031] Through the above arrangement, manual labor is reduced and production efficiency is improved. At the same time, the first and second in-place detection components improve the accuracy of hopper docking.

[0032] A rotating drive mechanism 43 electrically connected to the control system is provided on one side of the docking barrel 41. The rotating drive mechanism 43 is fixed on the docking frame 2, and a horizontal sealing plate 44 is fixedly connected to its driving end. The horizontal sealing plate 44 rotates around the driving end of the rotating drive mechanism 43 under the action of the rotating drive mechanism 43, and has a first sealing position for closing the bottom opening of the docking barrel 41 and a first opening position away from the bottom opening of the docking barrel 41.

[0033] Through this setting, the horizontal sealing plate ensures that the docking barrel will not cause leakage in the non-operating state. When there is a need to connect materials, the hopper is pushed into the docking frame, and the first in-place detection component on the docking frame detects the hopper in-place signal and sends it to the control system. The control system first sends a signal to the rotary drive mechanism, and the rotary drive mechanism drives the horizontal sealing plate to rotate to the first open position, and the control system then sends a signal to the lifting drive mechanism. Among them, the rotary drive mechanism is specifically a rotary cylinder.

[0034] The docking frame 2 is provided with a third in-place detection component for detecting whether the horizontal sealing plate 44 is located at the first open position, and the third in-place detection component is electrically connected to the control system.

[0035] Through this arrangement, the horizontal sealing plate rotates to the first open position, and the third in-place detection component sends an in-place signal to the control system, which then sends a signal to the lifting drive mechanism, thereby further improving the accuracy and safety of the operation of the device.

[0036] The outer periphery of the upper end of the docking barrel 41 is connected with a first connecting plate 411 , and two lifting drive mechanisms 42 are provided and located at opposite sides of the docking barrel 41 . The driving end of the lifting drive mechanism 42 is detachably fixedly connected to the upper end of the first connecting plate 411 .

[0037] This arrangement further improves the stability of the lifting drive, and the detachable fixed connection between the driving end and the first connecting plate facilitates disassembly, installation, and maintenance. The detachable fixed connection is specifically connected by a threaded member.

[0038] The automatic valve opening assembly includes an actuator 51 and a transmission shaft 52 driven to rotate by the actuator 51 . The transmission shaft 52 is provided with an opening member 53 that rotates synchronously. The opening member 53 cooperates with the transmission plug 111 of the control valve 11 to realize the opening and closing of the control valve 11 .

[0039] The automatic valve opening assembly also includes a telescopic drive mechanism 54 horizontally fixed on the docking frame 2, and a slider 55 is connected to the driving end of the telescopic drive mechanism 54. The actuator 51 is fixed on the slider 55 and can move horizontally with the slider 55 under the drive of the telescopic drive mechanism 54 to have a first working position close to the control valve 11 and cooperating therewith and a first closing position away from the control valve 11.

[0040] With this arrangement, the position of the actuator can be adjusted by the telescopic drive mechanism, thereby preventing the actuator and other components from interfering with the hopper during non-operation or when the hopper is moved in and out.

[0041] The docking frame 2 is fixed with a slide rail 56 parallel to the moving track of the slider 55 above and / or below the moving track of the slider 55, and the slider 55 is fixed with a sliding connector 57 that matches the shape of the slide rail 56 and forms a sliding fit.

[0042] Through this arrangement, the slide rail forms a limiting effect on the driving of the sliding block by the telescopic driving mechanism, thereby improving the stability of the movement of the sliding block, thereby improving the stability of the opening and closing control of the control valve.

[0043] The docking frame 2 is fixed with a second connecting plate 58 above the slider 55 , and the two ends of the slide rail 56 are detachably connected with end connecting blocks 59 . The upper end of the end connecting block 59 is fixed to the bottom of the second connecting plate 58 and limits the sliding connector 57 from separating from the slide rail 56 .

[0044] Through this arrangement, the stability of the movement of the slider is further improved, and the stability and safety of the opening and closing control of the control valve are improved.

[0045] The control valve 11 is a butterfly valve.

[0046] Four first in-place detection components 31 are provided and are respectively located on the four legs 21 of the docking frame 2 .

[0047] Through this setting, the accuracy of hopper arrival detection is further improved.

[0048] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
