Abstract
The utility model discloses a circular hole cutting knife roller, which comprises a crankshaft, a roller, a knife rest fixing plate and punching needles, wherein an installation through hole is arranged at the axis center of the roller, the roller is movably sleeved on the surface of the crankshaft through the installation through hole, a plurality of clamping grooves are arranged on the surface of the roller, the knife rest fixing plate is fixedly arranged in the clamping grooves, and a plurality of punching needles which are uniformly distributed are arranged on the knife rest fixing plate; the utility model discloses can be used to the operation of trompil on the plastic film, the trompil mode punches a hole for the cylinder now, needs the cylinder of many sets to accomplish the operation of this patent, because reciprocating motion can be extravagant very big compressed air often to the cylinder, causes air compressor's transitional use, consumes a large amount of electric energy, uses the utility model discloses the device both can improve trompil efficiency, also need not many sets of cylinder work compressed air, reduction in production cost that can be very big.
Description
Technical Field
The utility model relates to a rotor especially relates to a circle cutting hole rotor.
Background
At present plastic film's trompil mode is punched a hole for the cylinder, needs many sets of cylinders to carry out work during the trompil, because the cylinder is reciprocating motion often and can waste very big compressed air, causes air compressor's transition to use, consumes a large amount of electric energy, has improved the trompil cost.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a circular cutting hole knife roll which can be used for the operation of punching holes on plastic films and can greatly reduce the production cost.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model provides a circle cutting hole rotor, includes bent axle, roller, knife rest fixed plate and perforating needle, the axle center department of roller is provided with the installation through-hole, the roller has the surface of bent axle through installation through-hole movable sleeve, the surface of roller is provided with a plurality of draw-in grooves, knife rest fixed plate fixed mounting is in the draw-in groove, just install a plurality of evenly distributed's perforating needle on the knife rest fixed plate.
As an optimal technical scheme of the utility model, the both ends of bent axle all are provided with the adapter sleeve, the both ends of roller are provided with the spread groove that corresponds with the adapter sleeve, the adapter sleeve clamps in the spread groove.
As an optimal technical scheme of the utility model, the knife rest fixed plate is the arc board, just the surface radian of arc board is the same with roller surface radian.
As an optimized technical proposal of the utility model, the needle point of the perforating needle penetrates out of the surface of the fixed plate of the tool rest.
Compared with the prior art, the utility model discloses the beneficial effect that can reach is:
the utility model discloses can be used to the operation of trompil on the plastic film, the trompil mode punches a hole for the cylinder now, needs the cylinder of many sets to accomplish the operation of this patent, because reciprocating motion can be extravagant very big compressed air often to the cylinder, causes air compressor's transitional use, consumes a large amount of electric energy, uses the utility model discloses the device both can improve trompil efficiency, also need not many sets of cylinder work compressed air, reduction in production cost that can be very big.

Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Referring to fig. 1-3, a circular hole cutting knife roll comprises a crankshaft 1, a roller 2, a knife rest fixing plate 3 and punching needles 4, wherein an installation through hole is formed in the axis of the roller 2, the roller 2 is movably sleeved on the surface of the crankshaft 1 through the installation through hole, a plurality of clamping grooves are formed in the surface of the roller 2, the knife rest fixing plate 3 is fixedly installed in the clamping grooves, and the punching needles 4 are evenly distributed on the knife rest fixing plate 3.
The two ends of the crankshaft 1 are both provided with connecting sleeves 5, the two ends of the roller 2 are provided with connecting grooves corresponding to the connecting sleeves 5, and the connecting sleeves 5 are clamped in the connecting grooves and pass through the connecting grooves.
The tool rest fixing plate 3 is an arc plate, and the surface radian of the arc plate is the same as that of the roller 2, so that the surface of the roller 2 is kept to be a cylindrical surface, and the roller is convenient to rotate and tension a plastic film.
The needle point of the perforating needle 4 penetrates out of the surface of the cutter frame fixing plate 3, so that the perforating needle 4 can perforate the plastic film which enters the surface of the roller 2.
Specifically, the utility model discloses bent axle 1 is the fixed axle, and roller 2 is rotary part, and the plastic film tensioning passes through roller 2's top surface to it is rotatory to drive roller 2, and when roller 2 was rotatory drive perforating needle 4 and knife rest fixed plate sword 3 when through 1 peak of bent axle, perforating needle 4 jack-up can pierce through the plastic film of cladding on roller 2, thereby accomplishes the operation of punching.
The embodiments of the present invention are not limited to the above embodiments, and according to the contents of the above embodiments of the present invention, the above preferred embodiments can also make modifications, replacements or combinations of other forms by using conventional technical knowledge and conventional means in the field without departing from the basic technical idea of the present invention, and the obtained other embodiments all fall within the scope of the present invention.
