Technical field
The utility model belongs to disposable sanitary articles production equipment manufacturing field more particularly to a kind of elastic cutting dress
It sets.
Background technique
In general, two-piece type or three-chip type are drawn in the manufacturing processes of disposable sanitary articles such as trousers, are needed first
Continuous elastomeric element (such as elastic) is fixed on the specific position of non-woven fabrics by hot melt adhesive, just fixes position not
Together, above-mentioned elastomeric element is broadly divided into: waist portion two-side elastic component and middle leg portion S-shaped elastomeric element, due to subsequent need
Across the two-side elastic component of absorptive core is configured on non-woven fabrics, in order to avoid the elastic components contract at absorptive core is formed
Unnecessary fold, therefore also needed the specific position on the non-woven fabrics with elastomeric element will before absorptive core configuration
It cuts off, to eliminate the elasticity of elastic on the region.
Cutting roller and anvil roller are mostly overall structure in existing elastic disconnecting device, i.e., uniaxial by a uniaxial rotor and one
Anvil roller is cut off, and since material wide cut is big, rotor processing cost is high, and is changed code and adjusted inconvenience, is easily occurred in use process
Heat distortion causes product cutting ineffective.
For another example Chinese Patent Application No. is 201810189150X, a kind of elastic disconnecting device is disclosed, although the patent mentions
The design for having gone out for cutter rotor, anvil roller to be all divided into two groups of cutting assemblies reduces rotor and occurs flexible deformation's after stress
May, but the device can only cut off waist portion two-side elastic component, and middle leg portion S-shaped elastomeric element can not be eliminated
Elasticity.Further, since cutting assembly and anvil roller assembly are all made of split type, it will appear device in the operating condition of 400ppm/min
The abnormal serious defect of shake.

Rotor phase.
Further, the horizontal distance between the first cutting rotor and the second cutting rotor is adjustable, is so set
It sets to facilitate and switch between multiple specification products, shortening changes a yard time, improves escape efficiency.Further, on knife rest also
It is provided with the regulating mechanism for adjusting pressing force between cutting rotor and anvil roller, which can be cylinder or adjusting
Bolt.
Further, it is additionally provided with heater on the anvil roller, can so guarantee to cut off effect while prevents to heat
The attachment of glue.
The utility model has the beneficial effects that
Rotor assembly is improved to split type by the utility model on existing single axle device basic, specifically includes difference
The first cutting rotor, the second cutting rotor of cutoff process are carried out to material two sides elastic, and are used for material middle leg portion S rubber
The third of muscle cutting cuts off rotor, reduces the difficulty of processing and manufacturing cost of cutting rotor, extends the service life of rotor；
Meanwhile present apparatus force stress is more balanced, and anti-resonance vibration is had excellent performance, and is applicable to two-piece type, three-chip type draws trousers in height
Processing under fast operating condition.To sum up, the utility model has the advantages that cut off that effect is good, debugging cycle is short, long service life, can one
Secondary two sides elastic and middle leg portion S elastic to material is cut off, therefore highly efficient in productivity.
Below with reference to drawings and examples, the utility model is described in detail.
