Description
Technical Field
The utility model relates to the technical field of machinery, in particular to a double-system unreeling structure.
Background
In traditional cutting machine system of unreeling, the unwinding process of material is controlled to general exclusive use motor braking or air brake braking, and when only using motor control, the control reaction is fast, and the undulant sensitivity of control little tension, but meet big roll of footpath material, the high speed state, motor control can't in time feed back, and only use air brake control, to big roll of footpath material, the high speed state can in time react, but to the little roll of footpath material, low-speed, tension control is not as well as motor control. There is therefore a need to address this problem.
SUMMERY OF THE UTILITY MODEL
The utility model provides a double-system unwinding structure, which aims to solve the technical problem that the unwinding of coiled materials can be influenced by a single unwinding structure, and the double-system unwinding structure is characterized in that a motor brake and an air brake are simultaneously installed on an unwinding mechanism of a splitting machine.
The technical scheme adopted by the utility model for solving the technical problem is as follows: a dual system unreels structure, it includes: the method comprises the following steps: the fixing base, fixing base one side lower extreme fixed connection driving motor, driving motor output end fixed connection second synchronizing wheel, the second synchronizing wheel passes through the transmission hold-in range transmission and connects first synchronizing wheel, second synchronizing wheel one side and fixing base rotate to be connected, the fixing base is close to the pneumatic brake of driving motor one side upper end fixed connection, pneumatic brake one side fixed connection transmission shaft, pneumatic brake one side fixed connection mechanical cone top is kept away from to the transmission shaft, fixing base one side fixed connection drum material is kept away from to the mechanical cone top, through having installed two kinds of modes of unreeling simultaneously in unreeling system for the material can be adjusted the selection according to tensile size when unreeling.
As a preferred technical scheme of the utility model: the middle part of the first synchronizing wheel is fixedly connected with the transmission shaft, and the transmission shaft penetrates through the first synchronizing wheel, so that the first synchronizing wheel can drive the transmission shaft to rotate.
As a preferred technical scheme of the utility model: two transition rollers are installed at the upper end of the cylinder material, so that the material can be conveniently unreeled.
The utility model has the following advantages: through unreeling structurally at a cutting machine, install a driving motor braking and an air brake simultaneously, when using the motor braking, under the speed mode, the tension fluctuation when the control that can be fine is unreeled at a low speed, and use the air brake braking, under the torque mode, the tension fluctuation when the control that can be fine unreels at a high speed can adapt to big tension and little tension, makes the tension scope of cutting machine adaptation obviously increase, has solved the material that appears under the single mode and has unreeled the problem.

Detailed Description
The utility model will be further explained with reference to the drawings.
Referring to fig. 1-2, the present invention provides a technical solution: a dual system unreeling structure comprising: fixing base 3, driving motor 2 of lower extreme fixed mounting in 3 one sides of fixing base, and output fixed connection second synchronizing wheel 6 at driving motor 2, then make second synchronizing wheel 6 be connected with the transmission of first synchronizing wheel 4 through the drive hold-in range 5 that sets up, and make 6 one sides of second synchronizing wheel and fixing base 3 rotate and connect, again with 1 fixed mounting of pneumatic brake be close to driving motor 2 one side upper end with fixing base 3, then with 1 one side of pneumatic brake and 8 fixed connection of transmission shaft, and keep away from 1 one side fixed connection mechanical vertex of a cone 7 of pneumatic brake at transmission shaft 8, then install drum material 9 and keep away from 3 one side of fixing base at mechanical vertex of a cone 7.
Wherein, in order to make first synchronizing wheel 4 can drive transmission shaft 8 and rotate, at first synchronizing wheel 4 middle part and transmission shaft 8 fixed connection, and let transmission shaft 8 run through first synchronizing wheel 4.
Wherein, in order to facilitate the unreeling transportation of the materials, two transition rollers 10 are arranged at the upper end of the cylinder material 9.
Specifically, when the utility model is used, a cylindrical material 9 with a film coiled material is arranged on a mechanical conical top 7, then the film coiled material is pulled to be transported from a transition roller 10 in a limiting way through two transition rollers 10, when the coiled material can be unreeled only by needing larger tension, the pneumatic brake 1 can be used for adjusting the friction force on a transmission shaft 8 to determine, when the coiled material needs smaller tension to be transported quickly, the driving motor 2 can be started, the driving motor 2 drives the second synchronous wheel 6 to rotate, the second synchronous wheel 6 drives the first synchronous wheel 4 to rotate through the transmission synchronous belt 5, and the transmission shaft 8 is driven to rotate by the first synchronous wheel 4, so that the transportation of the coiled material is accelerated.
