Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to a chain conveyor for equidistant conveying of cathode plates. Background Technique

[0002] At present, the wet zinc smelting process has become the mainstream in zinc smelting plants. In the whole wet zinc smelting process, it is necessary to strip the zinc sheets electrodeposited on the cathode plates. There are two common methods for stripping zinc sheets. One is manual stripping, and the other is full-automatic stripping using an automatic zinc stripping unit. The main equipment of the automatic zinc stripping unit is a zinc stripping machine. Automatic feeding and material taking equipment need to be set before and after the zinc stripping machine to convey the cathode plates equidistantly to the zinc stripping machine. After the zinc stripping of the cathode plates, they are transferred through the automatic material taking equipment.

[0003] The automatic feeding and material taking of the zinc stripping machine are mainly completed by a chain conveyor. At present, the conveyor drive mainly uses a frequency conversion motor, and at the same time, it needs to cooperate with a variety of sensors and an electric control system to complete the normal material taking and feeding work. This motor-driven conveyor needs to frequently start and stop the motor during the conveying process of the cathode plates and ensure that the cathode plates can be accurately positioned each time they are conveyed. With the promulgation of "GB18613-2020 Limits and Energy Efficiency Grades of Motors", the procurement cost and control cost of its drive device have both increased significantly.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 is a schematic structural diagram of the chain conveyor for equidistant conveying of the cathode plate provided by the present utility model;

[0015] Figure 2 is Figure 1 the enlarged view of part A in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Please refer to Figure 1 and Figure 2 simultaneously, which are respectively the structural schematic diagram of the chain conveyor for equidistant conveying of the cathode plate provided by the present invention and the enlarged view at position A therein.

[0018] The chain conveyor for equidistant conveying of the cathode plate includes a frame 001. On both sides of the top of the frame 001, there are provided a conveying chain driving sprocket 004, a conveying chain driven sprocket 003, and a conveying chain 002 surrounding the two. The conveying chain driving sprocket 004 is provided at the right end of the frame 001, and the conveying chain driven sprocket 003 is provided at the left end of the frame 001. The frame 001 forms a cathode plate transportation channel between the two conveying chains 002.

[0019] At the bottom of the right end of the frame 001, there are also provided a driving oil cylinder 008, a driving shaft 013, a swing arm 009, and a one-way clutch 010.

[0020] The end of the driving oil cylinder 008 far from the piston rod head is hinged with a support 007 by a pin shaft, and the support 007 is fixedly connected to the frame 001. The piston rod head end of the driving oil cylinder 008 is hinged with one end of the swing arm 009 by a pin shaft. The other end of the swing arm 009 is fixedly connected to the outer ring of the one-way clutch 010, and the inner ring of the one-way clutch 010 is fixedly sleeved on the driving shaft 013.

[0021] The driving shaft 013 is provided below the cathode plate transportation channel, and its two ends are respectively located on both sides of the frame 001. Both ends of the driving shaft 013 are fixedly sleeved with pedestal bearings 014 and driving sprockets 011. The bearing seats of the pedestal bearings 014 are fixedly connected to the frame 001.

[0022] A driven sprocket 005 is also fixedly sleeved on the shaft of the conveying chain driving sprocket 004, and the driven sprocket 005 is key-connected to the shaft.

[0023] Tensioning wheels 006 are also provided on both sides of the frame 001. The wheel seats of the tensioning wheels 006 are fixedly connected to the frame 001 by bolts. The wheel seats of the tensioning wheels 006 are also provided with adjusting screws 015. One end of the adjusting screw 015 is fixedly connected to the wheel seat of the tensioning wheel 006, and the other end is threadedly connected to the frame 001.

[0024] On both sides of the frame 001, drive chains 012 are also provided. The drive chains 012 surround the drive sprockets 011, the driven sprockets 005, and the tensioning wheels 006 on the same side.

[0025] During specific implementation, the cathode plates are placed between the two conveying chains.

[0026] The drive cylinder 008 extends, driving the swing arm 009 to rotate clockwise. At this time, the one-way clutch 010 is locked, and thus the drive shaft 013 can be driven to rotate. As the drive shaft 013 rotates, power is transmitted via the drive sprocket 011 and the drive chain 012 to the driven sprocket 005, driving the conveying chain drive sprocket 004 to rotate, and further moving the conveying chain 002.

[0027] When the drive cylinder 008 extends to a preset length and then retracts, during the retraction process, the drive cylinder 008 drives the swing arm 009 to rotate counterclockwise. At this time, the one-way clutch 010 is not locked, and the drive shaft 013 does not rotate. That is, during the retraction process of the drive cylinder 008, the conveying chain 002 does not move.

[0028] The drive cylinder 008 repeats the above-mentioned extension and retraction operations, enabling the intermittent equidistant movement of the conveying chain 002, and realizing the intermittent equidistant transmission of the cathode plates on the conveying chain 002.

[0029] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
