A kind of hole drill mechanism that has the paper scrap automatic collecting device
The utility model relates to the office equipment field, is the hole drill mechanism that a kind of binder is used, particularly a kind of hole drill mechanism that can utilize drilling tool structure to realize collecting automatically paper scrap.
Along with society and expanding economy; The increase that the generation of various tickets and transmission capacity are a large amount of; The a large amount of notices, file, record, machine account and the written information that are accompanied by various societies and economic activity remain irreplaceable raw file data, are historical important witness, human civilization historical facts carriers.Normalized bookbinding and filing have become the whole society, and each forms necessary work of unit and the vital task under the legal system.Document of the prior art and bill binder are convenient to use, great convenience are provided for people's live and work.The waste paper scrap of supervening when the binder that order uses carries out work, what have does not have a special recovering mechanism, but directly is emitted on the desk tops; Influence the clean and tidy of desk, cleaning is got up pretty troublesome, have because structural limitations; Cause chip removal to have some setbacks; Take place to stop up so that breaking has brought inconvenience to the operator, therefore be necessary the chip removal structure of binder is improved.
Summary of the invention
The utility model has some setbacks, is prone to take place to stop up the technical problem of breaking phenomenon for the chip removal mode that solves binder; Designed a kind of hole drill mechanism that has the paper scrap automatic collecting device; Through improving the chip removal mode; Utilize to bore centrifugal force and the subnormal ambient that the cutter rotation produces paper scrap discharged from the core drill cutter, and finally through the chip removal of chip removal conduit to bits collecting box, solved the problem that existing binder chip removal has some setbacks, is prone to take place the obstruction breaking.
The utility model for realizing the technical scheme that goal of the invention adopts is; A kind of hole drill mechanism that has the paper scrap automatic collecting device; Comprise the brill cutter in the structure, bore cutter and realize and being located by connecting of drive motors axle, channel of chip removal axially is set along what bore cutter and drill bushing by drill bushing; The collection that drill bushing and outer cover dress is positioned on the casing is considered tubular complete tubular structure to be worth doing, and channel of chip removal is opened in first crumb mouth of drill bushing and second crumb mouth on the collection bits pipe is communicated with the chip removal conduit by corresponding respectively.
The beneficial effect of the utility model is: through improving the chip removal mode; Utilize the centrifugal force and the subnormal ambient that bore cutter rotation generation that paper scrap is discharged from the core drill cutter; And finally through the chip removal of chip removal conduit to bits collecting box; Not only solve the problem that existing binder chip removal has some setbacks, is prone to take place to stop up breaking, also kept the clean and tidy of desk simultaneously, saved manpower.
Below in conjunction with accompanying drawing the utility model is elaborated.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing, 1 represents casing, and 1-1 represents the drive motors axle, 2 representative collection bits pipes, and 2-1 represents second crumb mouth, and 3 represent drill bushing, and 3-1 represents second crumb mouth, and cutter is bored in 4 representatives, and 5 represent tube connector, and 6 represent the chip removal conduit, and 7 represent bearing, the remaining paper scrap of 8 representatives.
The specific embodiment
A kind of hole drill mechanism that has the paper scrap automatic collecting device; Comprise in the structure and bore cutter 4; Bore cutter 4 being located by connecting by drill bushing 3 realizations and drive motors axle 1-1; Along boring between cutter 4 and the drill bushing 3 channel of chip removal is set axially, drill bushing 3 forms sleeve type structures with the collection bits pipe 2 that the outer cover dress is positioned on the casing 1, and channel of chip removal is opened in the first crumb mouth 3-1 of drill bushing 3 and the second crumb mouth 2-1 that the collection bits are managed on 2 is communicated with chip removal conduit 6 by corresponding respectively.。Chip removal conduit 6 is connected with the second crumb mouth 2-1 by tube connector 5.
Above-mentioned drill bushing 3 forms with collection bits pipe 2 by bearing 7 and is rotatably assorted.
The bits end that goes out of above-mentioned chip removal conduit 6 is provided with bits collecting box, and bits collecting box is arranged on the support of binder bottom.
Chip removal conduit 6 is provided with vacuum suction valve 6-1; Vacuum suction valve 6-1 and vavuum pump are connected to form pumped vacuum systems, and pumped vacuum systems and borehole drill construction form the relation of being linked by main controller, when borehole drill construction is holed; Pumped vacuum systems is opened simultaneously; Make in collection bits pipe 2 and the chip removal conduit 6 and produce negative pressure, paper scrap gets into chip removal conduit 6 down, the completion chip removal boring the centrifugal force that the cutter rotation produces and the effect of subnormal ambient.
The utility model is when concrete the use: bore cutter 4 and be fixed on the drill bushing 3; The motor shaft 1-1 of drill bushing 3 and drilling motor links together; Collection bits pipe 2 is installed on the casing 1; Install through bearing 7 between drill bushing 3 and the collection bits pipe 2, tube connector 5 is fixed on the collection bits pipe 2, and chip removal conduit 6 is fixed on the tube connector 5.Boring cutter 4 is hollow, and drilling motor drives through drill bushing 3 and bores cutter 4 rotation at a high speed, in the process of boring paper; Lay the brill cutter 4 of next paper scrap, enter in the drill bushing 3, owing on the drill bushing 3 the first crumb mouth 3-1 is arranged through hollow; So paper scrap is thrown away in the collection bits pipe 2 by the drill bushing 3 of rotation at a high speed; Utilized the principle and the subnormal ambient of centrifugal force and freely falling body, the paper scrap that gets out has been dropped in the bits collecting box of binder bottom the row's of completion paper scrap process through tube connector 5 and chip removal conduit 6.Be present in the remaining paper scrap 8 that bores in the cutter 4 and can be bored the paper scrap jack-up that cutter produces in boring procedure,, in the drill bushing rotary course, be discharged from and bore cutter 4 up in drill bushing, being accumulated to certain altitude.
