Description

A kind of paper breaker

Technical field

The present invention relates to a kind of paper breaker, especially relate to a kind of paper breaker with machine core gear self oiling function.

Background technique

Paper breaker is a kind of office equipment commonly used, is used to pulverize discarded file.Because paper breaker is easy to use, become the essential product of constituent parts office and family just gradually.

Paper breaker is to utilize the rotation of its inner movement gear driven blade with the file severing.Existing paper breaker gear is seldom lubricated, causes the gear easy abrasion, thereby influences the normal operation of blade; Even perhaps be lubricated, also be to carry out after need taking the paper breaker cabinet apart, inconvenience operates.

Summary of the invention

The technical problem that the present invention mainly solves provides a kind of movement gear can keep lubrication effect, easy to operate paper breaker for a long time.

For solving the problems of the technologies described above, the present invention adopts following technological scheme: a kind of paper breaker, this paper breaker comprise one group of movement gear, two groups of blades and drive motor; The movement gear comprises first to fourth gear, first gear and the second gear interlock, the 3rd gear and the 4th gear interlock; Second gear and the 3rd gear are located in the same rotating shaft, and first gear connects motor, second gear and the 4th gear respectively with paper breaker in two groups of blades be connected; Said paper breaker also comprises automatic lubricator, and this automatic lubricator comprises gear housing, and first to fourth gear is contained in this gear housing; This gear housing bottom is formed with the oil groove that adds that is used to hold lubricant oil; This adds the lubricant oil height of placing in the oil groove and is lower than the junction point of these four gears and its rotating shaft, but is higher than the minimum point of arbitrary gear in these four gears, also offers at least one in order to inject the oil filler of this lubricant oil on this gear housing; Said oil filler place also is provided with sealed piece; This sealed piece is used to seal this oil filler, and this sealed piece is a sealing cork, perhaps is hard material and this oil filler threaded; The side plate of this gear housing and gear carrier cooperation place are provided with O-ring seal; The axle part cooperation place of the side plate of this gear housing and paper breaker is provided with O-ring seal, and the axle part cooperation place of the gear carrier of these four gears and paper breaker is provided with O-ring seal, and the drive motor cooperation place of the side plate of this gear housing and gear is provided with O-ring seal.

Paper breaker according to the invention is to form one through the gear housing bottom at automatic lubricator to add oil groove; Can movement gear dipping be added in the lubricant oil in the oil groove,, can directly inject lubricant oil through the oil filler on the gear housing;, gear can carry out self oiling simultaneously when rotating; And keep lubrication effect for a long time, need not to carry out the directly lubricated gear housing interpolation lubricant oil of perhaps taking apart in the paper breaker on the gear through manually lubricant oil being poured into repeatedly, it is comparatively convenient to operate; In addition; Refueling altitude in the gear housing is lower than these four gears and its rotating shaft junction point; In case gear possibly produce the gap and leakage of oil when rotating; And the drive motor of the gear carrier cooperation place of side plate on gear housing and gear, shredder shaft spare and this side plate or gear carrier cooperation place, gear and this side plate cooperation place possibly all be added with O-ring seal in the oily place of seepage, to prevent oil seepage.

Embodiment

As shown in Figure 1, as the embodiment of paper breaker according to the invention, this paper breaker 100 comprises first gear 10, second gear 20, the 3rd gear 30 and the 4th gear 40.This automatic lubricator comprises gear housing 50 and sealed piece 60.

First gear 10 and 20 interlocks of second gear; The

3rd gear

30 and 40 interlocks of the 4th gear; Second gear 20 and the 3rd gear 30 are located in the same rotating shaft 12; First gear 10 connects motor (figure does not show), and second gear 20 and the 4th gear 40 are connected with paper breaker 100 interior two groups of blades (figure does not show) respectively.

Gear housing 50 is the casing of a hollow, and its bottom forms one and adds oil groove 51, the first gears 10, second gear 20, the 3rd gear 30 and the 4th gear 40 and all be arranged in the gear housing 50.Also offer an oil filler 52 on the shell of gear housing 50; Oil filler 52 is a through hole, leads to the inside of gear housing 50, and oil filler 52 is through sealed piece 60 sealings; Sealed piece 60 is a sealing cork in the present embodiment, and it can directly fill in oil filler 52 with its sealing.Sealed piece 60 also can be hard material, as is a hard spiral shell inspection, at this moment, is formed with screw thread on the inwall of formation oil filler 52, sealed piece 60 and these oil filler 52 threaded.

The roughly working principle of gear housing 50 internal gears is following: first gear 10 14 rotates under the driving of motor around the shaft, and second gear 20 of drive and its interlock 12 rotates around the shaft, and second gear 20 drives connected one group of blade running; Simultaneously, the 3rd gear 30 that second gear 20 drives setting coaxial with it also 12 rotates around the shaft, thereby the 4th gear 40 of 30 drives of the 3rd gear and its interlock 16 is rotated around the shaft, makes the also running simultaneously of another group blade that is connected with the 4th gear 40; To put into the paper of paper breaker 100 in the time of two groups of blade runnings pulverizes.

Refueling altitude in the gear housing 50 is lower than these four gears and its rotating shaft junction point; In case gear possibly produce the gap and leakage of oil when rotating; And possibly all be added with O-ring seal in the oily place of seepage at gear housing 50 shells and other part junction; All be provided with O-ring seal like the drive motor of gear carrier cooperation place, shredder shaft spare and this side plate of side plate on the gear housing and gear or gear carrier cooperation place, gear and this side plate cooperation place etc., to prevent oil seepage.In addition, oil filler 52 also can be provided with a plurality of.

As shown in Figure 1, put into certain lubricant oil through oil filler 52, refueling altitude is positioned at and refuels on the line 70, and this oiling line is higher than the minimum point of arbitrary gear in first gear 10, second gear 20, the 3rd gear 30 and the 4th gear 40.With sealed piece 60 oil filler 52 is sealed after adding lubricant oil.During work,, when these three gears rotate, can lubricant oil be driven, make other teeth also by sufficient lubrication because the teeth of first gear 10, second gear 20 and the 4th gear 40 bottoms all are immersed in the lubricant oil in the gear housing 50.For the 3rd gear 30, though its teeth directly do not contact with the lubricant oil of gear housing 50 bottoms, also can be through the transmission of lubricant oil on the 4th gear 40 teeth by sufficient lubrication.

Paper breaker according to the invention adds oil groove 51 through forming one in gear housing 50 bottoms; Can gear be immersed in the lubricant oil that adds in the oil groove 51; In gear rotation carrying out simultaneously self oiling; Can keep lubrication effect for a long time, need not to carry out on the gear directly lubricating through manually lubricant oil being poured into repeatedly.In addition, offer oil filler 52 on the gear housing 50, can directly inject lubricant oil through oil filler 52, need not to take the gear housing 50 in the paper breaker 100 apart, it is comparatively convenient to operate.

The above is merely the preferred embodiments of the present invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
