Net belt variable-speed winding device for fabricating safety nets

Abstract

The invention discloses a net belt variable-speed winding device for fabricating safety nets. The net belt variable-speed winding device comprises a rack, a bottom plate of the rack is provided with vertical plates, a middle shaft and an upper shaft are connected between the vertical plates, one end of a lower shaft is further connected between the vertical plates, the other end of the lower shaftis connected with a motor through a clutch, the motor is installed on the outer side of the right vertical plate, the other end of the lower shaft is connected with a supporting plate, the supportingplate is vertically installed between the vertical plates, the lower shaft is connected with a driving gear train in a sleeved manner and the driving gear train is connected with a driven gear trainon the middle shaft in an engaged manner, a transition wheel on the middle shaft is connected with a power wheel on the upper shaft in an engaged manner, and one end of the upper shaft is connected with one end of a net roller through a coupler after running through the right vertical plate. The net belt variable-speed winding device for fabricating the safety nets is compact in structure and reasonable in design, rotating of a shaft and the net roller is controlled by the clutch, and the shaft is provided with an adjustable-speed wheel to control the rotating speed of the net roller, in addition, the supporting plate is strengthened to prevent the lower shaft from jumping, the stability of gear transmission is guaranteed, the net belt variable-speed winding device for fabricating the safety nets is more reliable in operation and more convenient to use than a traditional net winding device, especially, the net roller rotating-speed mechanical adjustment is suitable for winding of net belts of different specifications.

Description

technical field [0001] The invention relates to the technical field of safety net processing machinery, in particular to a mesh belt variable-speed winding device for manufacturing safety nets. Background technique [0002] Safety nets are used to prevent people and objects from falling, or to avoid and reduce falling and object damage. The safety net is generally composed of a net body, side ropes, tethers and other components. [0003] The safety net is a kind of labor protection equipment to prevent falling injuries. It has a wide range of applications and is mostly used for various high-altitude operations. The hidden danger of falling when working at heights often occurs on shelves, roofs, windows, suspensions, deep pits, deep grooves, etc. The degree of fall damage varies with the distance of the fall, ranging from disability to death. The protection principle of the safety net is: the function of the flat net is to block falling people and objects, avoid or reduce ...

AI Technical Summary

Problems solved by technology

[0004] After the safety net is woven by the machine, it needs to be wound up before it can be packaged into a finished product. However, the winding equipment used in the winding process cannot be adjusted due to the speed of the traditional winding equipment, or the speed is adjusted according to the motor. It is not conducive to the use of the same equipment to wind the fences of different specifications, or the equipment cost is increased, and the maintenance cost is too high, etc.
