Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] like Figures 1-3 As shown, a fluoropolymer-lined ball valve conveying mechanism includes a first double-speed chain conveyor 100, a second double-speed chain conveyor 200, a third double-speed chain conveyor 300, and a fourth double-speed chain conveyor 400 connected end to end to form a rectangular circulating conveyor line. The middle area of ​​the rectangular circulating conveyor line is provided with a number of processing stations 500 distributed along the rectangular circulating conveyor line. The rectangular circulating conveyor line is provided with a number of tooling plates for placing fluoropolymer-lined ball valves. A section of the fourth double-speed chain conveyor line is broken to form an inlet / outlet channel 410. The two ends of the fourth double-speed chain conveyor line at the inlet / outlet channel are connected by a lifting platform elevator 600, a fifth double-speed chain conveyor 700, and a lowering platform elevator 800. The lifting platform elevator, the fifth double-speed chain conveyor line, and the lowering platform elevator are connected to form a gantry structure. This invention utilizes a rectangular circulating conveyor line to transfer fluoropolymer-lined ball valves between different workstations, sequentially completing processes such as fitting, fastening, packing, opening and closing tests, pressure testing, and torque testing. This helps reduce manual labor, lower labor intensity, and improve production efficiency. Furthermore, the tooling plates used to support the fluoropolymer-lined ball valves can be reused repeatedly. In addition, the conveying mechanism makes full use of the space in the middle area of ​​the rectangular circulating conveyor line, setting the processing station on the inward side, thus occupying less floor space and improving space utilization.

[0021] In this embodiment, both the lifting platform elevator 600 and the lowering platform elevator 700 include a frame 610, a lifting frame 620 that can move up and down along the frame, and a chain drive mechanism for driving the lifting frame to move up and down. A roller conveyor 630 is mounted on the lifting frame. This gantry structure allows tooling plates to pass over the access channel, and the access channel in the middle of the gantry structure is used for workers and trolleys to enter and exit.

[0022] In this embodiment, the chain drive mechanism includes a chain 640 and a counterweight frame 650. A drive sprocket is provided at the top of the frame, and a driven sprocket is provided at the bottom of the frame. The chain is installed on the drive sprocket and the driven sprocket. A section of the chain is broken off on one side, and the two ends of the break are fixedly connected to the top and bottom of the lifting frame. A section of the chain is also broken off on the other side, and the two ends of the break are fixedly connected to the top and bottom of the counterweight frame.

[0023] In this embodiment, a drive motor connected to the active sprocket drive is provided on the top of the frame.

[0024] In this embodiment, the chain drive mechanism is provided in two sets, and the two driving sprockets of the two sets of chain drive mechanisms are coaxially arranged through a rotating shaft. The rotating shaft is connected to the drive motor through the sprocket and the transmission chain.

[0025] In this embodiment, a pair of first guide rails located on both sides of the lifting frame and a pair of second guide rails located on both sides of the counterweight frame are fixedly connected to the frame. The lifting frame is in sliding or rolling engagement with the first guide rails, and the counterweight frame is in sliding or rolling engagement with the second guide rails.

[0026] In this embodiment, the discharge ends of the first, second, third, and fourth double-speed chain conveyors are all equipped with a first lifting and transplanting machine 900. The first lifting and transplanting machine at the discharge end of the first double-speed chain conveyor transfers the tooling plate to the second double-speed chain conveyor, the first lifting and transplanting machine at the discharge end of the second double-speed chain conveyor transfers the tooling plate to the third double-speed chain conveyor, the first lifting and transplanting machine at the discharge end of the third double-speed chain conveyor transfers the tooling plate to the fourth double-speed chain conveyor, and the first lifting and transplanting machine at the discharge end of the fourth double-speed chain conveyor transfers the tooling plate to the first double-speed chain conveyor.

[0027] In this embodiment, several processing stations are distributed beside the first, second, and third double-speed chain conveyor lines. The tooling plate is unloaded before reaching the fourth double-speed chain conveyor line and entering the lifting elevator. After passing through the gantry structure, the tooling plate is loaded onto the fourth double-speed chain conveyor line.

[0028] In this embodiment, the first, second, third, and fourth double-speed chain conveyors are equipped with stoppers at set positions (including loading point, unloading point, and various workstations) to block the tooling plates.

[0029] In this embodiment, a second lifting and transplanting machine 1000 is provided at each processing station on the first, second, and third double-speed chain conveyor lines to transport the tooling plate to the processing station.

[0030] In this embodiment, each processing station 500 is equipped with a support roller conveyor 510 for receiving tooling plates. The second lifting and transplanting machine transports the tooling plates into the support roller conveyors of each station. After the worker takes the fluoropolymer-lined ball valves from the tooling plates and completes the corresponding processing steps, the worker puts the tooling plates back on. After all the fluoropolymer-lined ball valves on the tooling plates have been processed, the worker pushes the tooling plates back to the conveyor line.
