A kind of bullet handle grinding device of embodiment
Present embodiment discloses a kind of bullet handle grinding devices, as shown in Figure 1, including successively being fixedly mounted on rack 1 from top to bottom
On feed mechanism, crushing roller 3 and discharge mechanism 5.
The present embodiment is in order to be evenly dispersed into the wooden bullet handle from transport mechanism on feed mechanism, and gradually successively
Fall on crushing roller 3, so avoid being fallen by the blanking port 7 of transport mechanism feed mechanism bullet handle blocking feed mechanism and shadow
Ring working efficiency.Specific embodiment is: feed mechanism includes feed leakage bucket 2, the discharge port of feed leakage bucket 2 by rack 1 top
Crushing roller 3 is stretched to vertically, and feed leakage bucket 2 and rack 1 are rotatablely connected.As shown in Fig. 2, the top of rack 1 is equipped with the first drive
Motivation structure 6 is to drive feed leakage bucket 2 to do uniform circular motion along its axis.First driving mechanism 6 is driven including gear ring 601, first
Dynamic motor 603 and the driving wheel 602 for being fixedly mounted on 603 output shaft end of the first driving motor.Wherein, 601 fixing sleeve of gear ring
On 2 lateral wall of feed leakage bucket, gear ring 601 is overlapped with the axis of feed leakage bucket 2, and the first driving motor 603 is mounted in rack 1,
For bevel gear, it is meshed driving wheel 602 with gear ring 601, and the blanking port 7 of transport mechanism is located above the edge of feed leakage bucket 2.It is main
It is at the uniform velocity round that driving wheel 602 drives gear ring 601 that feed leakage bucket 2 is driven to do along the axis of feed leakage bucket 2 under the driving of the first driving motor 603
Zhou Yundong so that by transport mechanism transmission Lai material be homogeneously dispersed in the inner wall surrounding of feed leakage bucket 2.And due to feed leakage bucket 2
It moves in a circle, play handle has certain delay, Jin Ershi under the action of centrifugal force and self gravity on the inner wall of feed leakage bucket 2
It now plays before handle enters crushing roller 3 and is buffered, feed leakage bucket 2 will not be blocked to roller to play handle and can sequentially enter, and play handle and fall
When entering crushing roller 3, crushing roller 3 will not be bounced off when crushing roller 3 contacts due to playing the excessive velocities of handle.
The present embodiment again can in order to further make bullet handle so that 2 pairs of bullet handles of feed leakage bucket is obtained buffering when falling into feed leakage bucket 2
Handle will smoothly be played to export to crushing roller 3, as shown in figure 3, the first horn-like structure 201 of feed leakage bucket 2 including coaxial line and the
The bigger diameter end of two horn-like structures 202, the miner diameter end of the first horn-like structure 201 and the second horn-like structure 202 is connected and two
Person's radius is equal, and the taper of the first horn-like structure 201 is greater than the taper of the second horn-like structure 202, and the first horn-like knot
The taper difference range of structure 201 and the second horn-like structure 202 is 25 ° -35 °, and preferred taper difference is 30 °.Handle is played to initially enter
Top in first horn-like structure 201 is gradually slid under the action of gravity and centrifugal force in the second horn-like structure 202,
Since the taper along its axis of the second horn-like structure 202 is smaller, playing handle will not stop on it, and smoothly slide into crushing pair
It is crushed on roller 3.
As shown in figure 4, crushing roller 3 include the first roller 301 and with the first roller 301 be arranged side by side the second roller 302, first
Roller 301 is parallel with the axis of the second roller 302 and is located in same level, and the first roller 301 and the second roller 302 are respectively by turning
Axis 303 and rack 1 are rotatablely connected.Crushing roller 3 drives it to bullet handle by being mounted on the second driving mechanism 4 of 1 side of rack
It is crushed, the second driving mechanism 4 includes first be coaxially mounted in the shaft 303 of the first roller 301 and the second roller 302 respectively
Gear 401 and second gear 402, first gear 401 and second gear 402 are intermeshed, and the second driving electricity is equipped in rack 1
Machine 403 is coaxially installed with the third gear 404 being meshed with first gear 401 on second driving motor, 403 output shaft.First
Roller 301 and the second roller 302 drive third gear 404 to drive first gear 401 and the under the driving of the second driving motor 403
Two gears 402 move toward one another, and then the bullet handle fallen between the first roller 301 and the second roller 302 under constituting carries out rolling crushing.This
Embodiment is played when handle falls into crushing roller 3 in order to prevent there is a phenomenon where rebounding, the outer surface of the first roller 301 and the second roller 302
On be formed uniformly spine, due to play handle be wooden structure, play handle under backwardness can by the spine of opposite position pierce in, and
It is rotated with the first roller 301 or the second roller 302, to realize crushing.
As shown in figure 4, discharge mechanism 5 and rack 1 are rotatablely connected, biography is configured between discharge mechanism 5 and crushing roller 3
Dynamic component, transmission component do discharge mechanism 5 back and forth with the rotation connection axis 504 of rack 1 along it
Movement, the smashed disintegrating slag on discharge mechanism 5 is smoothly exported.Keep about 5 discharge mechanism past since transmission component plays
Multiple vibration, playing handle disintegrating slag will not be piled up on discharge mechanism 5 under the action of vibration and influence discharge.Wherein, transmission component packet
The partial gear 501 being mounted in the shaft 303 of the first roller 301 is included, is installed in discharge mechanism 5 and the connecting shaft 504 of rack 1
There is driven wheel 502, and partial gear 501 and driven wheel 502 are located at the same side, the two sides at the discharge gate of discharge mechanism 5 point
The spring 503 that both ends are fixedly connected with rack 1 and discharge mechanism 5 respectively is not installed.When partial gear 501 is with shaft 303
When rotating and engaging with driven wheel 502, discharge mechanism 5 is rotated up 20 ° -30 ° along connecting shaft 504, and spring 503 is at this time
Stretch energy accumulating state；When partial gear 501 engages disappearance with driven wheel 502, discharge mechanism 5 is under the action of spring 503
It is rotated up along connecting shaft 504 to initial position.Repeatedly, make discharge mechanism 5 diagonally downward at 30 ° of angle with horizontal plane
Position, be swung down to 50 ° -60 ° of position, so make play handle disintegrating slag be smoothly discharged.
The course of work of the embodiment of the present invention is as follows:
The first driving motor 603 and the second driving motor 403 are opened, handle is played by transport mechanism and is conveyed to feed mechanism, feeding
Mechanism carries out dispersion to supplied materials and supplied materials is successively imported to crushing roller 3, and crushing roller 3 crushes to form disintegrating slag by handle is played, disintegrating slag
Output mechanism is fallen into, output mechanism does the reciprocating motion along connecting shaft 504 by transmission mechanism, disintegrating slag is fully discharged.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in power of the present invention
Within the scope of benefit is claimed.
