Description

[0001] The utility model belongs to buffering device technical field, concretely relates to a steel band buffering device and unloading machine. BACKGROUND

[0002] In the foamed ceramic production line, the unloading machine is used to unload the finished foamed ceramic plate. The existing unloading machine generally uses a chain wheel and chain lifting structure driven by a conventional three-phase motor. A set of special buffer device is additionally installed between the clamping device and the chain. The buffer device prevents the stacked foamed ceramic plate from being crushed when the unloading machine contacts the finished foamed ceramic plate. Most of the current buffer devices use hydraulic cylinders as the buffer power source. Therefore, the buffer device needs to be equipped with a complete hydraulic system, such as a hydraulic oil tank, hydraulic pipelines, and cables throughout the unloading machine. The hydraulic fluid leakage of the hydraulic system is inevitable and can occur at any connection point, i.e., the hydraulic system has safety hazards. When a fault occurs, the maintenance cost is high and the downtime is long. In addition, the hydraulic fluid is greatly affected by temperature. In winter, the hydraulic oil is prone to condensation, which reduces the buffering efficiency and even stops the machine. Shutdown is very dangerous for foamed ceramic production because long-term shutdown may cause the kiln to stop, and the cost of restarting the kiln is generally hundreds of thousands of yuan. Therefore, it is necessary to propose a new buffer device and a new unloading machine. SUMMARY

[0039] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, the specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0040] As Figures 1-7 shown, the present application proposes a steel belt buffering device 1, which comprises an upper frame 101, a lower frame 105, a steel belt lifting mechanism and a guide mechanism. The steel belt lifting mechanism is arranged on the upper frame 101, and the steel belt lifting mechanism is connected with the lower frame 105 to control the lifting of the lower frame 105. The guide mechanism is used to guide the lifting of the lower frame 105. The technical solutions of the present application will be described in detail below with specific structures.

[0041] As Figures 2-7 shown, the steel belt lifting mechanism comprises a lifting motor 102, a winch 103 and a steel belt 106. The lifting motor 102 and the winch 103 are arranged above the upper frame 101. One end of the steel belt 106 is connected with the winch 103, and the steel belt 106 is wound on the winch 103. The winch 103 controls the release and retraction of the steel belt 106. The upper frame 101 is provided with a steel belt 106 avoiding hole. The steel belt 106 is fixedly connected with the lower frame 105 through the steel belt 106 avoiding hole.

[0042] The guide mechanism comprises a guide cylinder 104 and a guide rod 108, the guide cylinder 104 is vertically fixedly arranged on the upper frame 101, the guide rod 108 penetrates the guide cylinder 104, and the bottom end of the guide rod 108 is fixedly connected with the lower frame 105. Preferably, a bearing cooperating with the guide rod 108 is arranged in the guide cylinder 104, so as to reduce the lifting resistance of the guide rod 108.

[0043] The steel band lifting mechanism controls the lifting of the lower frame 105, but the steel band 106 itself is flexible and cannot control the stability of the lower frame 105 during lifting, and the guide mechanism can effectively prevent the lower frame 105 from shaking during lifting.
