Porcupine roller can move up and down, and it is drive roll that rubber, which serves as a contrast roller, itself be connected by power motor and its speed reducer；Porcupine roller
For driven voller, itself can only be rotated, itself is simultaneously not connected to motor.Upper compressed steel roller itself can also adjust height and position
It sets.
In summary (non-essential supplement):
By the way of rotation porcupine roller punching, by the punching Spreading requirements setting punching of copper foil aluminium foil on cylindrical roller drum surface
Needle.Perforating needle can inlay fixed (bonding) on porcupine roller sleeve external surface, can also be straight on porcupine roller sleeve external surface
It connects and is processed into taper needle one by one.Porcupine roller is driven voller, adjustable above and below position, porcupine roller both ends be equipped with porcupine roller position adjust up and down and
Positioning device, with guarantee porcupine roller penetrate copper foil or aluminium foil depth size it is suitable.Porcupine roller following settings rubber serves as a contrast roller, punches hour hands
Saturating copper foil or aluminium foil are pricked in roller decline simultaneously has sub-fraction to penetrate in rubber lining roller, and rubber serves as a contrast roll material high resilience, when copper foil or
When disengaging after aluminium foil punching with rubber lining roller, rubber serves as a contrast roller elastic reset.Copper foil or aluminium foil after punching pass through in a pair
Lower steel pressure roller (two roller gaps are adjustable and lock), can suitably flatten more pin hole burr prominent after punching.
Unwinding device unreels shaft end equipped with magnetic powder brake or mechanical friction brake, generated when for unreeling punching compared with
For constant tension (generate stable unreel resistance).Porcupine roller is driven voller, adjustable above and below position, and porcupine roller both ends are equipped with porcupine roller position
Set up and down adjustment and positioning device, with guarantee porcupine roller penetrate copper foil or aluminium foil depth size it is suitable.It is speed regulation electricity that rubber, which serves as a contrast roller,
The cornerite large contact surface of the drive roll that machine drives, copper foil or Aluminium Foil Package on rubber lining roller are larger to be not easy to skid；Rubber serves as a contrast roller
Positioned at porcupine roller in the following, porcupine roller declines the saturating copper foil of bundle or aluminium foil and has sub-fraction to penetrate in rubber lining roller when punching, rubber serves as a contrast roller
Material high resilience, when disengaging after copper foil or aluminium foil punching with rubber lining roller, rubber serves as a contrast roller elastic reset.Above and below a pair of
Steel pressure roller is that drive roll and rubber serve as a contrast same motor driven of roller；Distance is adjustable between upper and lower two steel pressure rollers, two roller gaps
It, can be by more pin hole hair prominent after punching when latched position after adjustment is appropriate, copper foil or aluminium foil are by a pair of steel pressure roller up and down
Thorn is appropriate to be flattened.Wrap-up is controlled using the form of the additional magnetic powder cluth transmitting winding power of winding motor and is kept permanent
Fixed winding torque and winding tension are constant, and the copper foil or aluminium foil after guaranteeing punching are wound into neat reel.Length gauge setting
It is mounted on the upper surface of power-driven roller, the length of metering punching copper foil or aluminium foil.
In a creative way, above each effect is individually present, moreover it is possible to the combination of the above results is completed with a nested structure.
It is clear that the technical effect that the above structure is realized is realized, if the additional technical solution is not taken into account, this patent title is also
It can be a kind of novel holing structure.Part details is not shown in the figure.
It should be noted that multiple schemes that this patent provides include the basic scheme of itself, independently of each other, not mutually
It restricts, but it can also be combined with each other in the absence of conflict, reach multiple effects and realize jointly.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of this field
Personnel should be recognized that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this hairs
Bright principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these variations
It is both fallen in claimed range with improving.
