As Figure 1-Figure 2, wherein feed mechanism 2 includes the rotating cylinder 26 that screw 100 is delivered to feed mechanism 3, rotating cylinder 26 is connected with screw storehouse 21 level equipped with screw 100, as can be seen from Figure 2, the screw storehouse 21 of this embodiment is the round platform fallen down, the upper bottom surface of round platform and the center of bottom surface are at same level axle, and its bottom surface is connected with rotating cylinder 26 so that the bottom in screw storehouse 21 is downward-sloping；Be provided with flitch 28 on polylith in the inner side of rotating cylinder 26, and be provided be connected with stock support 36 draw flitch 210；Gear ring 25 it is provided with on rotating cylinder 26, and connection has a pan feeding motor 27 making its oscilaltion campaign, this pan feeding motor 27 is connected with the driven gear wheel 23 being arranged on feed mechanism 3 both sides by mair motor gear 29, the driven gear wheel 23 of both sides is connected to a cylinder drive gear 24, the engagement of cylinder drive gear 24 and gear ring 25 is connected, and i.e. the rotation of rotating cylinder 26 is simultaneously by the control of cylinder drive gear 24 of both sides；Draw flitch 210 and be each provided with one in the both sides of screw track 32, and relatively for screw track 32, draw flitch 210 upwards and towards outer incline.
Illustrating in conjunction with the above-mentioned structure about feed mechanism 2, the process that feed mechanism 2 completes feeding is as follows:
(1), put into the screw 100 in screw storehouse 21, owing to the bottom in screw storehouse 21 is downward-sloping so that screw 100 is prone to fall on rotating cylinder 26, and be respectively on each upper flitch 28；
(2), after machine startup, pan feeding motor 27 drives mair motor gear 29 to rotate, and mair motor gear 29 drives driven gear wheel 23 to rotate, and driven gear wheel 23 drives cylinder drive gear 24 to rotate；
(3), cylinder drive gear 24 cylinder 26 is rotated by gear ring 25 and rotates, the screw 100 being on each upper flitch 28 rotates along with the rotation of rotating cylinder 26；After being placed in certain height, screw 100, along upper flitch 28, is flowed into and draws flitch 210, enters feed mechanism 3 along drawing flitch 210；
(4), after screw 100 arrives certain height, screw 100 slides along upper flitch 28, is flowed into and draws flitch 210, enters feed mechanism 3 along drawing flitch 210；.
In conjunction with the above-mentioned description about feed mechanism 2, this feed mechanism 2 is described as follows compared to the beneficial effect of prior art:
(1), it is provided with flitch 28 and draws flitch 210, screw 100 is served the effect of guiding, and not as prior art only relies on unstable probability produced by irregular movement locus, add screw 100 and arrive the probability of screw recess 33 and in the stability of upper spiral shell probability, thus improve work efficiency；
(2), the noise that in this drum type brake, friction between collision and screw 100 and shell between each screw 100 is caused, compared to vibrating disk in vibrating-disk and for shaking caused noise in a large number between screw 100, relatively small, and reduce the phenomenon of card spiral shell, thus reduce fault rate.
(3), owing to being provided with guiding, i.e. in the case of screw 100 is less, this a small amount of screw 100 still can be made to arrive certain height, thus drop on feed mechanism 3, it is made to maintain certain upper spiral shell probability, so that this material-uploading style overcomes the revolving defect of cylinder in prior art, there is stronger adaptability.
(4), cylinder 26 to be rotated and rotates be jointly to be driven by both sides cylinder drive gear 24, and compared to for the structure that single-wheel drives, stability during rotation is higher, and it is more accurate to control, and the probability broken down is relatively low.
As shown in Figure 1-Figure 3, wherein feed mechanism 3 includes that stock support 36, stock support 36 are arranged on the inside of rotating cylinder 26 and screw storehouse 21, and is connected with drawing flitch 210；The both sides of stock support 36 connect vibrations suspension 31, stock support 36 is provided with the screw track 32 for carrying screw 100, screw track 32 includes the screw recess 33 accommodating screw 100, the width of screw recess 33 is more than the lead screw width of screw 100, and less than the screw terminal width of screw 100, stock support 36 is connected with vibrations cam 34 by vibrations roller 38, shakes cam 34 in the structure with vibrations roller 38 intersection as shown in Figure 3: be the visite that the gradient is bigger behind the long slope that the gradient is less；Vibrations cam 34 connects has one to drive gear 35 for its vibrations rotated, and these vibrations drive gear 35 to engage connection has vibrations travelling gear 37, vibrations travelling gear 37 to connect a driven gear wheel 23 making it rotate.
Illustrating in conjunction with the above-mentioned structure about feed mechanism 3, the process that feed mechanism 3 completes feeding is as follows:
(1) screw 100, drawn on flitch 210 starts inside landing, thus fall on screw track 32, now, the lead screw of segment screw 100 is down, when contacting with screw track 32, fall in screw recess 33, owing to the width of screw recess 33 is less than the screw terminal width of screw 100, so the screw terminal of screw 100 is stuck in screw recess 33；
(2), driven gear wheel 23 is rotated by the drive of pan feeding motor 27, vibrations travelling gear 37 is driven to rotate, vibrations travelling gear 37 drives vibrations to drive gear 35, thus drive vibrations cam 34 to rotate, vibrations cam 34 contacts with the vibrations roller 38 being fixed on stock support 36, thus drives the screw 100 in screw recess 33 to travel forward.
Illustrate in conjunction with said mechanism about the structure of feed mechanism 3 and complete the process of feeding, being described as follows about the proal principle of screw 100 in screw recess 33:
(1), climb up, when vibrations roller 38, the visite that the gradient is bigger, extruding between vibrations roller 38 and vibrations cam 34 produces a thrust backward, now, owing to the gradient is bigger, within the of short duration time, the distance of horizontal displacement is bigger, the thrust produced is more than the stiction between screw recess 33 and screw 100, make to move respectively between screw recess 33 and screw 100, it is more than the force of sliding friction between screw recess 33 and screw 100, so the distance that screw recess 33 is moved is than screw more than 100 backward owing to acting on the thrust of screw recess 33；
(2), when shaking roller 38 and again slipping into the less long slope of the gradient, the position that screw 100 falls before the position ratio in screw recess 33 is forward, the i.e. relative screw recess 33 of screw 100 is advanced, now there are certain elastic vibrations and hang 31 because being started resilience by a thrust backward before, make to shake roller 38 to move slowly on the long slope that the gradient is less, now, the dynamics acting on stock support 36 is less, it is not enough to offset the stiction between screw recess 33 and screw 100, so screw recess 33 and screw 100 keep geo-stationary, but screw 100 along with before screw recess 33 so that advance.
(1) and (2) in sum, in including the whole cycle of long slope and visite, the mass motion of screw recess 33 be backward motion after move the most forward, its initial position keeps consistent with final position, and screw 100 is less due to the distance moved backward, distance forward is more, so its final position is more forward than initial position, so that screw 100 travels forward slowly.
nullSuch as Fig. 1-Fig. 2，Shown in Fig. 4-Fig. 7，Wherein sweeping through the material mechanism 4 includes the hairbrush 41 being arranged on above screw track 32，Hairbrush 41 is connected with hairbrush pitman shaft 46 by hairbrush connecting plate 42，Tail end at hairbrush pitman shaft 46 connects a brush gear 43，Brush gear 43 is engaged on a brush gear connecting rod 44，This brush gear connecting rod 44 is fan-shaped，Brush gear connecting rod 44 connects hairbrush push rod roller 45，As we can see from the figure，On connecting plate between brush gear connecting rod 44 and hairbrush push rod roller 45 fluted，Coordinate with the limited screw being arranged on side，Thus hairbrush push rod roller 45 is carried out spacing and protection，Connect on hairbrush push rod roller 45 and have a hairbrush cam 47 making it move up and down，Hairbrush cam 47 connects a driven gear wheel 23 making it rotate.
In conjunction with Fig. 7, as follows about the structure specification of hairbrush cam 47: in terms of four sides of hairbrush cam 47, to be labeled as A, B, C, D, wherein the cross section of A side is semicircle, and rotate centrally disposed for semicircular circle, when making it run with A face, hairbrush push rod roller 45 remains constant with the distance in A face, and wherein the cross section of B, D side is the line segment being parallel to each other, wherein the cross section of C side is the waveform of three semicircle compositions, C1、C2、C3For the point of respectively three semicircles, C1、C3For two points farthest from the central pivot point rotated, C2For a point nearest from the central pivot point rotated.
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:
(1), driven gear wheel 23 is rotated by the drive of pan feeding motor 27, band electric brush cam 47 rotates, hairbrush cam 47 band electric brush push rod roller 45 moves up and down, hairbrush push rod roller 45 drives brush gear connecting rod 44 to move, when the left side of brush gear connecting rod 44 rises or falls 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 to rotate clockwise, so that hairbrush 41 carries out motion back and forth；
(2), the spacing between hairbrush 41 and screw recess 33 is shorter, in the lead screw of screw 100 does not falls within screw recess 33, screw 100 couches above screw recess 33, and the hairbrush 41 moved back and forth is inswept, the screw 100 not falling within screw recess 33 is swept by hairbrush 41, falls in screw storehouse 21.
Illustrate and carry out the work process of sweeping through the material in conjunction with the above-mentioned structure about sweeping through the material mechanism 4, about being described as follows that hairbrush cam 47 band electric brush push rod roller 45 moves up and down:
(1), as shown in Figure 4, the central pivot point rotated with electric brush cam 47 is arranged on the semicircular center of circle, as when the hairbrush push rod roller 45 A face at hairbrush cam 47, owing to being always maintained at constant from the center rotated, so hairbrush push rod roller 45 remains stationary as, now hairbrush 41 is positioned at the left side of stock support 36, and the description about left side and right side is with stock support 36 as reference in this paragraph；
(2), along with turning clockwise, when the hairbrush push rod roller 45 B face at hairbrush cam 47, the B face of hairbrush cam 47 from the central pivot point rotated increasingly away from so that hairbrush push rod roller 45 constantly rises under the effect of hairbrush cam 47, hairbrush 41 does counterclockwise movement, i.e. moves right；As it is shown in figure 5, as the C reaching C face1Time, now hairbrush 41 is positioned at the right side of stock support 36, i.e. completes the left side process to right side, and this is sweeping through the material action for the first time；
(3), as shown in Figure 6, then landing to the C in C face2Time, now hairbrush 41 is positioned at the left side of stock support 36, i.e. completes the right side process to left side, and this is second time sweeping through the material action；
(4), then landing to the C in C face3Time, now hairbrush 41 is positioned at the right side of stock support 36, i.e. completes the left side process to right side, and this is third time sweeping through the material action；
(5), being then return to D face, now hairbrush 41 returns to the left side of stock support 36, i.e. completes the right side process to left side, and this is the 4th sweeping through the material action；
(6), finally, A face is returned to from D face, circulation.
To sum up during (1) to (6), about the design of hairbrush cam 47, produced by have the beneficial effect that: hairbrush cam 47 is during rotating a circle, and hairbrush 41 carries out four sweeping through the material actions altogether, simultaneously because from C1To C2、C2To C3During the time shorter, so speed, the sweeping through the material dynamics of formation is relatively big, so that sweeping through the material result is more preferable.
