Below with reference to the accompanying drawings and in conjunction with the embodiments, the present invention is described in detail:

As Figure 1-Figure 8 for embodiments of the invention, the screw automatic arrangement machine that this embodiment provides, including frame 1, on Material mechanism 2, feed mechanism 3, sweeping through the material mechanism 4, feeding distribution mechanism 5 and gas-stopping mechanism 6, coordinate Figure of description 1-8 to come respectively below Composition mechanism is described in detail, and the most each Figure of description, in order to see structure and the details of inside more intuitively, simplifies Members.

As Figure 1-Figure 4, wherein feed mechanism 2 includes the screw lifting push pedal that screw 100 is delivered to feed mechanism 3 210, the top of screw lifting push pedal 210 is inwardly angled domatic, and screw lifting push pedal 210 is arranged on screw storehouse base plate 21 On, and it is each provided with one in the both sides of feed mechanism 3, have one to make it upper and lower as it is shown in figure 1, screw lifting push pedal 210 connects The pan feeding motor 27 of elevating movement, screw lifting push pedal 210 is to slide up and down on the opening that screw storehouse base plate 21 is arranged, And be arranged on the inner side of screw storehouse base plate 21, screw storehouse base plate 21 the lifting push pedal 210 of its relative screw Outboard Sections and Front part all slopes inwardly, i.e. screw lifting push pedal 210 is positioned at the minimum point of screw storehouse base plate 21, screw storehouse base plate 21 with give Material support 36 and shell not shown in the diagram are assembled into storing screws 100 and each side screw storehouse 211 of；Machine Be provided with the lifting carriage track 28 for screw lifting push pedal 210 motion on frame 1, pan feeding motor 27 by mair motor gear 29 with The screw lifting being arranged on feed mechanism 3 both sides drives gear 23 to connect, screw lifting drive gear 23 by a straight-bar and Play the screw lift drive shaft seat 22 of fixation, connect and have a lifter cam 25, be fixed on the liter on lifter cam 25 Fall slide bar 24 is slidably connected with the lifting slider 26 being fixed in screw lifting push pedal 210.

Illustrating in conjunction with the above-mentioned structure about feed mechanism 2, the process that feed mechanism 2 completes feeding is as follows: put into screw The screw 100 in storehouse 211, due to the intilted design of screw storehouse base plate 21 so that screw 100 is prone to fall and lifts push pedal at screw On 210, after machine startup, pan feeding motor 27 drives mair motor gear 29 to rotate, and mair motor gear 29 drives screw lifting to drive Moving gear 23 rotates, and screw lifting drives gear 23 to drive lifter cam 25 to rotate, and during rotating, is fixed on lifting convex Lifting slide bar 24 on wheel 25 rotates with lifter cam 25, thus carries out the circular motion in vertical direction, and by vertical direction On change in displacement by lifting slider 26 act on screw lifting push pedal 210 on, screw lifting push pedal 210 along lifting carriage Track 28 carries out moving back and forth of rise and fall, when screw lifting push pedal 210 rises to peak, due to inwardly angled slope Face, the screw 100 in screw lifting push pedal 210 starts inside landing, thus falls on feed mechanism 3.

Illustrate and complete the process of feeding in conjunction with the above-mentioned structure about feed mechanism 2, the screw lifting for both sides pushes away How plate 210 coordinates is described as follows: the lifting slide bar 24 arranging both sides presents the angle of certain dislocation when original position so that The screw lifting push pedal 210 of both sides completes the raising and lowering of dislocation, and i.e. side is when rising, and opposite side is decline state or guarantor Hold motionless, i.e. complete alternately feeding.

In conjunction with the above-mentioned description about feed mechanism 2, this feed mechanism 2 illustrates such as compared to the beneficial effect of prior art Under: the upper spiral shell of both sides dislocation, for the mechanism that spiral shell is gone up in both sides simultaneously, the time halves, and on one side, spiral shell falls into the probability of feed mechanism 3 Compare basically identical with both sides, so efficiency improves close to twice；Due to screw 100 walk be linear motion, compared to impeller For what in formula, screw 100 was walked is circular motion, in this mechanism, the frequency of upper spiral shell is higher, and it is shorter i.e. to go up the spiral shell cycle, so efficiency Higher；Meanwhile, it is different from vibrating-disk and between vibrating disk and screw 100, shakes caused noise, swing type in a large number In the noise that caused of friction between collision and screw 100 and shell between each screw 100, in this feed mechanism 2, spiral shell Silk 100 is geo-stationary during rising, and screw 100 is the most sliding from screw storehouse 211 landing to screw lifting push pedal 210 It is dynamic, so noise is less；The area of screw lifting push pedal 210 is little, and when screw 100 is less, landing to screw lifts push pedal 210 On, screw 100 still can be made when rising to peak to fall on feed mechanism 3, and the arrangement machine of impeller-type, work as screw 100 is less, although cylinder is constantly rotating, but a small amount of bottom screw 100 can be deposited in the bottom of cylinder, without along with Cylinder and carry out bigger rolling, the probability that i.e. screw 100 falls on feed mechanism 3 greatly reduces, so this feeder Structure 2, when screw 100 is less, still can reach higher upper spiral shell rate.

As Figure 1-Figure 4, wherein feed mechanism 3 includes stock support 36, and the both sides of stock support 36 connect vibrations Hanging 31, be provided with the screw track 32 for carrying screw 100 on stock support 36, screw track 32 includes accommodating screw The screw recess 33 of 100, the width of screw recess 33 is more than the lead screw width of screw 100, and is less than the screw terminal of screw 100 Width, stock support 36 by vibrations roller 38 with vibrations cam 34 be connected, vibrations cam 34 with shake roller 38 phase Structure at friendship is as shown in Figure 4: be the visite that the gradient is bigger behind the long slope that the gradient is less；Vibrations cam 34 connects has one to revolve for it The vibrations turned drive gear 35, and these vibrations drive gear 35 to engage connection vibrations travelling gear 37, and vibrations travelling gear 37 is even Connect a screw lifting making it rotate and drive gear 23.

Illustrating in conjunction with the above-mentioned structure about feed mechanism 3, the process that feed mechanism 3 completes feeding is as follows: screw lifts Screw 100 in push pedal 210 starts inside landing, thus falls on screw track 32, now, and the lead screw of segment screw 100 Down, when contacting with screw track 32, fall in screw recess 33, owing to the width of screw recess 33 is less than the spiral shell of screw 100 Silk head width, so the screw terminal of screw 100 is stuck in screw recess 33；Screw lifting drives gear 23 by pan feeding motor 27 Drive rotate, drive vibrations travelling gear 37 to rotate, vibrations travelling gear 37 drives vibrations to drive gear 35, thus carries Dynamic vibrations cam 34 rotates, and vibrations cam 34 contacts with the vibrations roller 38 being fixed on stock support 36, thus drives screw Screw 100 in groove 33 travels forward.

Illustrate in conjunction with said mechanism about the structure of feed mechanism 3 and complete the process of feeding, about in screw recess 33 The proal principle of screw 100 be described as follows: when vibrations roller 38 climbs up the visite that the gradient is bigger, vibrations roller 38 and shake Extruding between moving cam 34 produces a thrust backward, much larger than the frictional force between screw recess 33 and screw 100, send The material distance backward moved of support 36 than screw more than 100, the distance that i.e. screw recess 33 is moved backward than screw more than 100, When shaking roller 38 and again slipping into the less long slope of the gradient, screw 100 falls the position before the position ratio in screw recess 33 Put forward, i.e. the relative screw recess 33 of screw 100 is advanced, and now has certain elastic vibrations and hangs 31 because being subject to before Start resilience to a thrust backward so that vibrations roller 38 moves on the long slope that the gradient is less slowly, now, make Less for the dynamics of stock support 36, it is not enough to offset the stiction between screw recess 33 and screw 100, so screw Groove 33 and screw 100 keep geo-stationary, but screw 100 is along with before screw recess 33 and then advance, i.e. including long slope With in the whole cycle of visite, the mass motion of screw recess 33 be backward motion after move the most forward, its initial position and end It is consistent that stop bit puts holding, and screw 100 is less due to the distance moved backward, and distance forward is more, so its final position It is more forward than initial position, so that screw 100 travels forward slowly.

As Figure 1-Figure 4, wherein sweeping through the material mechanism 4 includes that the hairbrush 41 being arranged on above screw track 32, hairbrush 41 lead to Crossing hairbrush connecting plate 42 to be connected with hairbrush pitman shaft 46, the tail end at hairbrush pitman shaft 46 connects a brush gear 43, hair Brush teeth wheel 43 is engaged on a brush gear connecting rod 44, and this brush gear connecting rod 44 is fan-shaped, and brush gear connecting rod 44 connects hairbrush Push rod roller 45, from the figure, it can be seen that fluted on the connecting plate between brush gear connecting rod 44 and hairbrush push rod roller 45, with The limited screw being arranged on side coordinates, thus hairbrush push rod roller 45 carries out spacing and protection, hairbrush push rod roller Connecting on 45 and have a hairbrush cam 47 making it move up and down, the vertical cross-section of hairbrush cam 47 is not rounded row, in this enforcement In example, Fig. 3 can obtain structure specifically is: side is semicircle, and side is the waveforms of three semicircle compositions, semicircle with Waveform is connected by the line segment being parallel to each other, and hairbrush cam 47 connects the screw lifting having to make it rotate and drives gear 23.

Illustrating in conjunction with the above-mentioned structure about sweeping through the material mechanism 4, the process that sweeping through the material mechanism 4 carries out sweeping through the material is as follows: screw lifts Driving gear 23 to be rotated by the drive of pan feeding motor 27, band electric brush cam 47 rotates, and hairbrush cam 47 band electric brush pushes away Bar roller 45 moves up and down, and hairbrush push rod roller 45 drives brush gear connecting rod 44 to move, when the left side of brush gear connecting rod 44 When rising or falling along with hairbrush push rod roller 45, due to lever principle, the right side of brush gear connecting rod 44 drives brush gear 43 Counterclockwise or rotate clockwise, so that hairbrush 41 carries out motion back and forth, the spacing between hairbrush 41 and screw recess 33 is relatively Short, in the lead screw of screw 100 does not falls within screw recess 33, screw 100 couches above screw recess 33, is moved back and forth Hairbrush 41 inswept, the screw 100 not falling within screw recess 33 is swept by hairbrush 41, falls in the screw storehouse 211 of both sides.
