Description
Technical field
The utility model is related to mechanical equipment technical fields, and in particular to a kind of diaphragm cutting machine expansion set.
Background technology
Diaphragm cutting machine is one of key equipment in lithium battery material diaphragm production process, and working method is with upright
Cutter is cut into the coiled material diaphragm of one fixed width in the device used in several relatively narrow diaphragm films.The traditional approach of diaphragm cutting machine
It is to be driven using one big motor, added with magnetic powder brake on unreeling shaft, is controlled by adjusting the electric current of magnetic powder brake
Its generated resistance is made, to control the tension of material surface.Magnetic powder brake is a kind of special automated execution element, it
It is to transmit torque by being filled in the magnetic powder of working clearance, the magnetic state of magnetic powder can be changed by changing exciting current, and then
Adjust the torque transmitted.Available for starting from scratch to the stepless speed regulation of synchronizing speed, suitable for high regime fine tuning and middle low power
Governing system.Be additionally operable to adjust torque with the method for adjusting electric current with ensure tension is kept constant in winding process uncoiling or
Rewinding tension control system.
At present, unreel diaphragm using gas expansion shaft installation in diaphragm cutting machine, the appearance and size of gas expansion shaft be it is changeless,
Therefore the diameter of paper tube placed on it is also changeless, is unfavorable for the cutting of different-diameter parent roll, increases cutting
It is difficult, it would be highly desirable to improve.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of simple in structure, design conjunction is provided
Reason, diaphragm cutting machine expansion set easy to use, disclosure satisfy that the cutting of different-diameter parent roll, increase its scope of application, carry
Height cutting efficiency, practicability are stronger.
To achieve the above object, the technical solution adopted in the utility model is：It includes distending ring, rib, tension spring, limiting
Baffle ring, compression spring；The distending ring is made of several arc splits, is connected between each arc split by tension spring；Described
The left and right sides of distending ring is embedded with rib, and the inner wall of rib is connect, and compression spring is embedded in distending by compression spring with distending ring
In ring, the outer end of compression spring is movably arranged in the limit stop ring being set on rib.
Further, the ring diameter of the distending ring is 5 cun.
Further, the limit stop ring is oval limit stop ring.
With the above structure, the utility model has the beneficial effect that：A kind of diaphragm cutting machine described in the utility model is used
Expansion set disclosure satisfy that the cutting of different-diameter parent roll, increase its scope of application, improve cutting efficiency, practicability is stronger, this reality
There is the advantages that simple in structure, setting is reasonable, low manufacture cost with novel.
Description of the drawings
It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is the structure sectional view of the utility model.
Fig. 2 be in Fig. 1 C-C to sectional view.
Reference sign：
Distending ring 1, rib 2, tension spring 3, limit stop ring 4, compression spring 5.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
Referring to as shown in Figure 1, present embodiment the technical solution adopted is that：The technical solution adopted is that：It is included
Distending ring 1, rib 2, tension spring 3, limit stop ring 4, compression spring 5；The distending ring 1 is made of several arc splits, each arc
It is connected between split by tension spring 3；The left and right sides of the distending ring 1 is embedded with rib 2, and the inner wall of rib 2 passes through pressure
Spring 5 is connect with distending ring 1, and compression spring 5 is embedded in distending ring 1, and the outer end of compression spring 5, which is movably arranged on, to be set on rib 2
In limit stop ring 4.
Further, the internal diameter of the expansion set body is 3 cun.
Further, the outer diameter of the expansion set body is 8 cun.
Further, the limit stop ring 4 is oval limit stop ring.
The operation principle of present embodiment：Since the internal diameter of expansion set body is 3 cun, when in use, expansion set body is installed
On a diameter of 3 cun of gas expansion shaft, after gas expansion shaft ventilates distending, limited by tension spring 3,8 cun are installed in the outer diameter of expansion set body
Paper tube, realize the cutting of the parent roll of 3-8 cun different-diameters.
With the above structure, present embodiment has the beneficial effect that：A kind of diaphragm described in present embodiment
Cutting machine expansion set disclosure satisfy that the cutting of different-diameter parent roll, increase its scope of application, improve cutting efficiency, practicability
Stronger, the utility model has the advantages that simple in structure, setting is reasonable, low manufacture cost.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the right of the utility model.
