Description
Technical field
The utility model is related to a kind of antioverloading Wire winding shafts, belong to firecrackers production wet method lead field.
Background technology
During firecrackers lead produces, need after drying wet lead in winding to take-up roller, then finished product enters
Library, the structure and working condition of take-up and pay-off device are：The setting reeler for being wound with the lead after drying is fixed on paying out reel, is received
Line roller is fixed on Wire winding shaft, and paying out reel and Wire winding shaft setting are received the lead on setting reeler with the rotation of same linear velocity
It is rolled onto on take-up roller, in actual motion, since various factors such as foozle and driving error lead to the speed of unwrapping wire
It is inconsistent with the speed of take-up, if the speed of unwrapping wire is smaller than the speed of take-up, it may appear that break lead, on the one hand broken end influences to draw
Line mass needs shutdown process after on the other hand breaking lead, influences production efficiency.
Utility model content
The technical problems to be solved in the utility model is：A kind of antioverloading Wire winding shaft is studied, the Wire winding shaft and take-up are passed through
The sliding of roller when solving take-up, causes to break line influence lead quality and break to draw because payingoff speed is less than take-up speed
The problem of needing shutdown process after line, influencing production efficiency.
The technical solution of the utility model is：A kind of antioverloading Wire winding shaft, including：Mandrel, nut and axle sleeve, axle sleeve are sleeved on
In mandrel, nut is connect with spindle thread, and baffle ring is cased between nut and axle sleeve, and axle sleeve includes sleeve base and support bar, axis
Set pedestal outer surface is provided with straight slot, and support bar is clamped with sleeve base by straight slot, is provided in sleeve base circular recessed
Slot a, support bar position corresponding with groove a, which is arranged in fluted b, groove a and groove b, is placed with spring, and spring plays support and makees
With for supporting support bar.Take-up roller can be made easily to be packed into Wire winding shaft using spring supporting.After take-up roller is packed into, support
Item contacts under spring force effect with take-up inner wall of rotary drum, generates certain frictional force.When payingoff speed is not less than take-up
When speed, take-up roller rotates synchronously under the force effect that rubs with Wire winding shaft；When payingoff speed is less than take-up speed, lead
Tightly, lead is more than the pulling force of take-up roller the frictional force between take-up roller and Wire winding shaft at this time.Take-up roller and Wire winding shaft
It produces relative rotation, generates slipping phenomenon, alleviate lead anxiety, avoid lead and be pulled off.
Preferably, the quantity of the straight slot is 3-5, and each straight slot is clamped a support bar so that shape on the outside of support bar
At a circle, convenient for putting on take-up roller, it is more convenient that take-up roller is put on again by tight spring.
Preferably, described mandrel one end is provided with baffle, and the diameter of the baffle is equal with the diameter of baffle ring, and baffle is used for
Limit shaft sleeve, baffle and baffle ring diameter are equal, and position-limiting action and beauty are played to the both ends of take-up.
Preferably, the quantity of the groove a is 3-5, and the groove a of wherein both sides is less than or equal to a distance from end face of shaft bush
5cm, guarantee support bar are stablized relatively with sleeve base position, may when lead tenses if groove a is too far from end face of shaft bush
The frictional force between take-up roller and Wire winding shaft can be caused uneven, influence the sliding between take-up roller and Wire winding shaft.
The utility model has the beneficial effects that：A kind of antioverloading Wire winding shaft is designed, compared with prior art, advantage is mainly：
When payingoff speed is less than take-up speed, lead is tensioned, and lead is more than take-up roller and take-up to the pulling force of take-up roller at this time
Frictional force between axis.Take-up roller produces relative rotation with Wire winding shaft, generates slipping phenomenon, alleviates lead anxiety, avoids
Lead is pulled off；
In addition present apparatus support bar and mandrel are clamped, and spring is placed in the closed pockets a that axle sleeve and support bar are formed and recessed
In the slot that slot b is formed, sound construction is easy to use.
