As shown in Fig. 2, the present embodiment 1 provides a kind of cross cutting knife assembly, including：Knife rest 1 and on the knife rest 1
And cutting roller 2, the smooth roll 3 being arranged above and below；The wherein described cutting roller 2 is equipped with cutter 21；In cross cutting, the cutting roller 2 is suitable
In driving cutter 21 to rotate, with to being die cut by the material to be die cut between the cutter 21 and smooth roll 3.
Specifically, the material to be die cut is such as, but not limited to the health such as adult diaper, sanitary napkin, baby paper diaper
Articles for use；The shape of the cutter 21 can be replaced according to actual demand；When cross cutting, the material to be die cut is such as, but not limited to by passing
Defeated band conveying, and the gap between smooth roll 3 and cutter 21 is pierced by；When material to be die cut passes through between smooth roll 3 and cutter 21
When gap, cutting roller 2 starts to rotate, and cutter 21 is driven and then to rotate, to realize that treating cross cutting material is die cut.
The cutting roller 2 is equipped with several described cutters 21；And the quantity phase of the quantity and cutter 21 of the smooth roll 3
Matching, and each smooth roll 3 is corresponded with each cutter 21 respectively.
Specifically, the quantity of the cutter 21 is arranged according to actual demand, and each cutter 21 is removably mounted on cutter
On roller 2, in order to replace cutter of different shapes.
Specifically, compared with the prior art described in background technology, the cross cutting knife assembly setting of the present embodiment it is multiple compared with
Short smooth roll 3, and each smooth roll 3 is corresponded with each cutter 21 respectively, it is more due to making whole smooth roll in the prior art into
Root teaches short smooth roll 3, reduces the smooth roll materials between each cutter 21, the cost of smooth roll materials is greatly saved；Every simultaneously
Smooth roll 3 is when contradicting corresponding cutter 21, more steadily so that each cutter 21 can ensure object to be die cut when rotating cross cutting
The cross cutting point uniform stressed of material, greatly improves cross cutting effect.
The lower section of each smooth roll 3 is equipped with lifting mechanism 4；The lifting mechanism 4 is suitable for driving corresponding bachelor 3 to moving up
It moves to preset height, so that there are the gaps being pierced by suitable for material to be die cut between the smooth roll 3 and corresponding cutter 21.
Specifically, compared with the prior art described in background technology, the cross cutting knife assembly of the present embodiment is to pass through lifting
Smooth roll 3 makes between smooth roll 3 and cutter 21 that there are the gaps passed through suitable for material to be die cut to preset height；Due to every smooth roll 3
Length is short, light-weight, do not need prodigious driving force can be achieved with lifting smooth roll 3 move up；Additionally by default lifting machine
The rising height of structure 4, avoidable smooth roll 3 moves up mistiming and strikes cutter 21, and causes to damage to cutter 21, and makes
It is simple in structure it is not necessary that spacing ring is arranged on cutting roller 2, the manufacturing cost of the cross cutting knife assembly of the present embodiment is also ad save, and
The service life of cutter 21 can also be extended twice.
Each smooth roll 3 is located in respective axes of rotation, and the shaft is located on a support base 5；And the lifting mechanism 4
It is moved up suitable for driving support base 5, to drive smooth roll 3 to move up.
Specifically, the smooth roll 3 is arranged a shaft, in order to which smooth roll 3 rotates；The smooth roll 3 is located at support by shaft
On seat 5, since the bottom of support base 5 is flat, exerts a force upwards convenient for lifting mechanism 4, to be lifted smooth roll 3, and can ensure light
Roller 3 smoothly moves up.
The support base 5 is mounted on by guiding mechanism 6 on a bottom plate 7；The guiding mechanism 6 includes guide rod；And
The support base 5 is suitable for moving up and down along guide rod.
Specifically, the both ends of the support base 5 are respectively equipped with guiding mechanism 6, to ensure that support base 5 moves down along guide rod
When dynamic, held stationary further ensures that held stationary during moving up of smooth roll 3；Pass through the guiding mechanism 6 at both ends, moreover it is possible to
It prevents support base 5 from left and right offset occurs, to prevent smooth roll 3 from left and right offset occurs, influences to be die cut effect.
The lifting mechanism 4 is cylinder, and on the bottom plate 7.
Specifically, the lifting mechanism 4 is located at the underface of support base 5；Drive smooth roll 3 to moving up by using cylinder
It is dynamic, and driven using cylinder, accurate cylinder driving trip can be preset, smooth roll 3 is made accurately to be moved to setting height,
Ensure that bachelor 3 will not strike cutter 21, and influences the service life and cross cutting effect of cutter 21.
The operation principle of the cross cutting knife assembly of the present embodiment is as follows：
When need to be die cut, corresponding smooth roll 3 is raised to by preset height by lifting mechanism 4 upwards, then in material to be die cut
After being transported to the gap between smooth roll 3 and cutter 21, cutting roller 2 starts to rotate, and cutter 21 is driven to rotate, while waiting being die cut
Material continuously passes through the gap between smooth roll 3 and cutter 21, and cutter rod 2 persistently drives cutter 21 to rotate, and mould is treated to realize
Cut the cross cutting of material.
The cross cutting knife assembly of the utility model can not only ensure that each cutter stress is equal by the way that multiple shorter smooth rolls are arranged
It is even, cross cutting effect is improved, and the service life of cutter can also be extended；In addition, the cross cutting knife assembly of the utility model with it is existing
Cross cutting knife assembly compare, reduce spacing ring, and smooth roll is moved by cutter by material web turn to be die cut, and smooth roll is reduced
Driving mechanism, greatly reduce manufacturing cost, the simplification of structure makes dismounting also very convenient.
Embodiment 2
