In addition with reference to figure 1, according to the pressing device of glue spraying gun 100 of the present invention, comprise the pushing member directly contacting with wound packages fluid sealant or packed fluid sealant, described pushing member comprises the first pushing member 13 and the second pushing member 14, the first pushing member 13 is in the form of annular discs and connected regularly, for example welding, arrive the tooth bar end of the rack-and-pinion device of glue spraying gun 100, and tubular element 7 interior can on the bearing of trend along tubular element 7, do before and after linear reciprocating motion, first pushing member 13 for pushing wound packages fluid sealant.The second pushing member 14 is configured to detachable member, and in the present embodiment, for being disposed on the first pushing member 13, it is for pushing packed fluid sealant.Preferably, described the first pushing member 13 can be made by plastics or any other applicable material.Wound packages fluid sealant or packed fluid sealant are placed between retaining member 8 and above-mentioned pushing member, and by pushing member, fluid sealant are pushed out to opening.
In addition, glue spraying gun 100 also comprises for driving the driving mechanism of pressing device.According to the driving mechanism of glue spraying gun 100 of the present invention, can comprise motor 16 as shown in Figure 2, and be connected to the transmission system between motor 16 and pressing device.Transmission system and motor 16 are placed in the accommodation space being formed by right side housing 10 and left side housing 11.Right side housing 10 and left side housing 11 are made of plastics.
The transmission system of using according in glue spraying gun 100 of the present invention will be described in detail in below.
Shown in the decomposition explosion figure of glue spraying gun 100, the transmission system of glue spraying gun 100 comprises the reducing gear and the rack-and-pinion device 26 that with reducing gear be connected direct connected with motor 16 as shown in Figure 2.Here, the reducing gear of transmission system is configured to planetary system 17.
Fig. 3 shows according to the exploded view of the planetary system 17 of the transmission system of glue spraying gun 100 of the present invention.First show the motor 16 of glue spraying gun 100, it can be any suitable motor, for example permanent magnet DC motor.Motor 16 has output shaft 161, and the output speed of motor 16 is controlled by speed disk 2 as shown in Figure 1.
Sun gear 401 on sun wheel carrier 40, the second gear ring 42 that is formed with inner tines, the framework 43 that forms output shaft 432, three planetary gears 47 that are positioned at the second gear ring 42 have formed fourth planet train 38.When the second gear ring 42 maintains static, under the rotating drive of sun gear 401, three planetary gears 47 can revolve round the sun by the central shaft around sun gear 401 in the central shaft rotation around self, revolution from the power of sun gear 401 by three planetary gears 47 is passed to framework 43(output shaft 432), framework 43 comprises three legs 431 that are assembled in three planetary gear 47 central shafts, with this, three planetary gears 47 just can drive output shaft 432 to rotate by driver framework 43 when revolution.Then, by the rack-and-pinion device 26 that will describe below, power is passed to tooth bar 12, drives tooth bar 12 to do linear reciprocating motion along fore-and-aft direction.In the situation that gear ring 42 is not fixed and can freely rotates, according to the characteristic of planet circular system, sun gear 401 cannot drive three planetary gears 47 to do revolution motion, so, framework 43 also just can not be driven, and the framework 43 at output shaft 432 places that are being connected with rack-and-pinion device 26 maintains static.Now, three planetary gears 47, around self central shaft 431 rotation, drive the second gear ring 42 to rotate simultaneously, now, there is no transmission of power to rack-and-pinion device 26.
The second gear-box halfbody 455 holds gear ring 42 in the inner, links together with the first gear-box halfbody 454, for example, be connected by screw.So, the first gear-box halfbody 454 and the second gear-box halfbody 455 are holding the planetary system 17 as reducing gear completely.
By axle supporting member, a pair of deep groove ball bearing 44 for example, the output shaft 432 being supported on the second gear-box halfbody 455 stretches out through the axis hole 451 on the second gear-box halfbody 455.End at output shaft 432 is installed with the output link-bevel gear 181 as planetary system 17.Therefore, equal the rotating speed of bevel gear 181 with the rotating speed of output shaft 432.
From Fig. 3, can also be clear that very much, the centre wheel rotation of the rotation of the output shaft 161 of motor 16 and planet circular system 35, planet circular system 36 and planet circular system 37 all extends along fore-and-aft direction.Meanwhile, adopt the planetary system 17 that volume is little, gearratio large, operate steadily as reducing gear, to carry out the function of transmitting rotational motion and deceleration, reduced the volume of glue spraying gun 100, make glue spraying gun 100 be more suitable for hand-held use
With reference to figure 4 and Fig. 5, show the rack-and-pinion device 26 according to the transmission system of glue spraying gun 100 of the present invention.
Rack-and-pinion device 26 comprises the output block with planetary system 17, i.e. the second bevel gear 182 of the first bevel gear 181 engagements.The second bevel gear 182 and cylindrical gear 29(Fig. 5) can be connected and fixed on by key the two ends of same back shaft 33 respectively, so the second bevel gear 182 is identical with cylindrical gear 29 rotating speeds.Wherein, the engagement of the tooth of cylindrical gear 29 and tooth bar 12 teeth, cylindrical gear 29 can drive tooth bar 12 to do rectilinear motion by rotation.
In the present embodiment, the tooth that cylindrical gear 29 and tooth bar 12 are engaged with each other is stepped tooth (as shown in Figure 7).Certainly, other suitable castellated shape also can be used, for example involute teeth.
By the engagement of the first bevel gear 181 and the second bevel gear 182, the output shaft 161 of motor 16 is transferred to back shaft 33 around rotatablely moving of its central axis, it is rotated around its central axis, and in the present embodiment, the central axis of output shaft 161 is perpendicular to the central axis of back shaft 33.Back shaft 33 can drive cylindrical gear 29 to rotate around rotatablely moving of its central axis, and at this, cylindrical gear 29 can drive tooth bar 12 to do rectilinear motion along fore-and-aft direction by the tooth engagement with tooth bar 12.Along with the direction of rotation of motor 16 outputs is different, the linear movement direction of tooth bar 12 is also contrary.
Above-mentioned pushing member is installed on the front end of tooth bar 12, the lasting output rotatablely moving along with the output shaft 161 of motor 16, tooth bar 12 drives pushing member to do rectilinear motion forward or backward, with this, push the packed fluid sealant being placed in tubular element 7, thereby fluid sealant is extruded to glue spraying gun 100 from opening.
Fig. 4 and Fig. 5 have also illustrated bushing bearing 30 and the deep groove ball bearing 31 of gear frame cover 27, gear framing holder 28, back shaft 33 and the jump ring 32 of fixed cone gear 182.
The locus of illustrating from the view of Fig. 1 and 2 is known, on fore-and-aft direction, motor 16 be arranged at planetary system 17 before, planetary system 17 be arranged at rack-and-pinion device 26 before.In the vertical direction, tubular element 7 is positioned at motor 16 and planetary system 17 tops, rack-and-pinion device 26 is positioned at the rear of tubular element 7, wherein, tooth bar 12 can be done straight reciprocating motion in tubular element 7, back shaft 33 and be installed on the rear that cylindrical gear 29 on back shaft 33 is positioned at tubular element 7.
In conjunction with Fig. 2 and 4, they show tooth bar 12 and are pulled to extreme position foremost, at this extreme position, along the total length of the glue spraying gun 100 of the linear movement direction of tooth bar 12, be glue spraying gun 100 fluid sealant holding part retaining member 8 foremost 120 and the rearmost end 110 of the tooth bar 12 of the rack-and-pinion device 26 of glue spraying gun 100 between distance.
The setting of said structure, make according to the length of glue spraying gun 100 of the present invention shorter, small volume.Correspondingly, reduced the requirement to the operation requisite space of glue spraying gun 100, particularly for existing glue spraying gun because narrow space or limited and can not operate or the situation of being inconvenient to operate will be eased.Equally, for example size and the weight of housing can be reduced to be used for packing the container of glue spraying gun 100.
As shown in Figure 6, the first bevel gear 181 and the first bevel gear 182 engagements, the second bevel gear 182 is realized interlock by back shaft 33 and cylindrical gear 29, cylindrical gear 29 and tooth bar 12 engagements, tooth bar 12 moves forward and backward in tubular element 7.Wherein, back shaft 33 be take longitudinal perpendicular V that the center of circle of the first bevel gear 181 is summit and glue spraying gun 100 and is biased to an angle theta, and longitudinally perpendicular represents with V in the drawings.Because back shaft 33 has angle theta with longitudinal perpendicular V of glue spraying gun 100, the crest top land that is installed on the cylindrical gear 29 on back shaft 33 also forms an angle theta with longitudinal perpendicular V of glue spraying gun 100, also forms an angle theta with the crest top land of the tooth bar 12 of cylindrical gear 29 engagement with longitudinal perpendicular V.As shown in Figure 6, the bearing of trend of tooth bar 12 is located substantially on the centerline of tubular element 7, and back shaft 33 is setovered from vertical direction, and glue spraying gun 100 overall width W1 are as shown in Figure 6 diminished.Fig. 7 is the perspective view of another angle of Fig. 6.Comparatively speaking, as back shaft 33, vertically arrange that glue spraying gun 100 overall widths will be greater than W1, make the volume of glue spraying gun 100 become large.
So, by tooth bar 12 being arranged to be different from being in tilted layout of vertical layout of prior art, according to the overall width W1 of glue spraying gun 100 of the present invention, reduced the corresponding volume that reduces glue spraying gun 100.Therefore correspondingly, make operator easily control glue spraying gun 100, and reduced the requirement of the operating space to using.Equally, for packing the container of glue spraying gun 100, for example size and the weight of housing can reduce.
In addition, as shown in Figure 1, the tooth bar 12 of glue spraying gun 100 comprises the knop 4 for operator's operation in rear end.While needing to load packed fluid sealant, user holds knop 4, and tooth bar 12 is pulled back, and then screws off retaining member 8, packed seal gum loading is downloaded in tubular element 7, then screws retaining member 8.
In addition, in order to strengthen the rigidity of tooth bar 12, at the back side of tooth bar 12, be provided with ribs 121.Preferably, the thickness of ribs 121 is equal to or less than the thickness of tooth bar 12, and the length of ribs 121 equals, and is preferably less than the length of tooth bar 12.
Below with reference to Fig. 8 to Figure 10 c, describe according to the delivery system 9 of glue spraying gun 100 of the present invention.
Delivery system 9 comprises release-push 19, release-push spring 21, slide block 20, sliding block spring 22, pushing block 23, pushing block spring 24, switch trigger 3, switch trigger spring 50, and the parts such as microswitch 25.
Pushing block 23 comprises insertion portion 231 and pushing portion 232, and its insertion portion 231 is installed on the second gear-box halfbody 455 of planetary system 17 the shank 456(Fig. 3 forming) slit 451 in.Pushing portion 232 has the first inclined-plane 233.The insertion portion 231 of pushing block 23 comprises end 236, when end 236 is configured to the bonding station in the recess 123 in joining gear ring 42 to, gear ring 42 is limited to rotate, now, the torque of motor 16 is delivered to the tooth bar 12 of rack-and-pinion device 26 by planetary system 17.The end 236 of pushing block 23 is when disengaged position that the recess 123 in from gear ring 42 is thrown off, as mentioned above, gear ring 42 can freely rotate, planetary system 17 can not transferring power, the tooth bar 12 of glue spraying gun 100 can be pulled by knop 4 by user and move backward, so that packed fluid sealant can be loaded in tubular element 7.
Release-push 19 comprises co-operating the second inclined-plane 191, the first inclined-plane 233 with pushing block 23.On release-push 19, also there is slit 192.
Release-push 19 comprises initial position and depressing position.When user loads wound packages fluid sealant or packed fluid sealant, user overcomes the active force of release-push spring 21 and presses release-push 19, it is moved, as shown in Figure 10 a to depressing position from initial position.The second inclined-plane 191 of release-push 19 and the first inclined-plane 233 butts of pushing block 23, and the active force that therefore overcomes pushing block spring 24 orders about pushing block 23 and moves along direction B.
Meanwhile, the main inclined plane 201 of butt slide block 20 is gone back on the second inclined-plane 191 of release-push 19, and the active force that overcomes sliding block spring 22 orders about moving slider 20 and move along direction C, and now, the slipper 205 of slide block 20 is along with moving along direction C together.Wherein, direction C is consistent with direction B.
When release-push 19 is pressed into depressing position from initial position, the end 236 of pushing block 23 is removed in the recess 123 of gear ring 42, and the slipper 205 of slide block 20 moves the edge part 197 that strides across release-push 19 simultaneously.Afterwards, under the effect of sliding block spring 22, engage and lock onto in the slit 192 of release-push 19, as shown in Figure 10 b.So, release-push 19 is locked and be held in depressing position.Now, gear ring 42 can freely rotate, and planetary system 17 no longer arrives rack-and-pinion device 26 by transmission of power.
As shown in Figure 10 b, release-push 19 in depressing position time, because the slipper 205 of slide block 20 is engaged and be locked in the slit 192 of release-push 19, release-push 19 can not be released button spring 21 and return, and glue spraying gun 100 is held in this state.Now user can hold knop 4, and tooth bar 12 is pulled back, and can realize the operation of loading wound packages fluid sealant or packed fluid sealant.
As shown in Figure 10 c, after the operation of loading wound packages fluid sealant or packed fluid sealant completes, user can, along direction of arrow push switch trigger 3, make microswitch 25(Figure 10 c of the fingers 303 triggering motors 16 of switch trigger 3), thereby starter motor 16.Should point out, can use the microswitch of any type conventional in this area to control motor 16 herein.
Switch trigger 3 comprises cantilever 301.Along with switch trigger 3 is pressed along the direction of arrow, the inclined-plane 203 of butt slide blocks 20 is understood on the inclined-plane 302 of cantilever 301, and promotes the inclined-plane 203 of slide block 20, makes slide block 20 also driven, and now, the slipper 205 of slide block 20 is driven to be moved along direction C.When the slipper 205 of slide block 20 shifts out the slit 192 of release-push 19, the lock-out state of the depressing position of release-push 19 is disengaged, and release-push 19 rebounds along direction F subsequently under the effect of release-push spring 21, discharges the restriction to pushing block 23 simultaneously.Now, under the effect of pushing block spring 24, along with the resilience of release-push 19, pushing block 23 moves along the direction H contrary with direction B.Now, under the effect of sliding block spring 22, main inclined plane 201 recoveries of slide block 20 and the butt on the inclined-plane 191 of release-push 19.Finally, release-push 19 can reset to initial position; The end 236 of pushing block 23 is re-engaged in the depression 123 of gear ring 42, and gear ring 42 can not freely be rotated, and recovers the transmission of power of planetary system 17 and rack-and-pinion device 26.Therefore, the torque of the motor 16 being activated changes moving forward of tooth bar 12 into via the transmission of the transmission system of glue spraying gun 100, and tooth bar 12 promotes pushing member the fluid sealant in wound packages fluid sealant or packed fluid sealant is extruded from opening, reaches the function of plastic squeeze.
In the present embodiment, release-push 19 is also provided with stop surface 193, as shown in Figure 10 b.Stop surface 193 is configured to by the cantilever 301 of switch trigger 3, be stopped when user presses switch trigger 3 and do not unclamp, thereby release-push 19 can not be pressed.Otherwise release-push 19 may be by inadvertent depression, cause the planetary system 17 can not transferring power, the operation of extruding fluid sealant surprisingly stops.The arranging of stop surface 193 guaranteed that glue spraying gun 100 can realize the operation of extruding continuously fluid sealant, thereby prevents from pressing because of unexpected the possibility that plastic squeeze interruption situation occurs release-push 19.
Glue spraying gun 100 according to the present invention can be released relatively full-bodied material.As everyone knows, because viscosity of material is high, often generating material increases at extrusion resistance the phenomenon that consequently speed to introduce of material slows down and even stops.For existing glue spraying gun, when increasing to certain numerical value, the electric current of motor can automatically cut off electric current, and motor shuts down, and therefore the operation meeting of extruding of glue spraying gun stops.
Yet advantageously, if there is the excessive situation of resistance when extruding heavy viscous material, glue spraying gun 100 according to the present invention can be realized the technique effect of extruding continuously heavy viscous material.Particularly, along with the increase of heavy viscous material release resistance, the electric current in motor 16 increases.When electric current increases to default a certain critical value, by user, preset and make motor 16 be supplied to a default small voltage, only impel the Nonstop running of motor 16, wait for that the release resistance of glue spraying gun 100 reduces.When resistance is reduced to a certain degree, motor 16 autoboots, the operation of extruding fluid sealant of glue spraying gun 100 recovers automatically.In this process, glue spraying gun 100 is supplied with the power of pushing fluid sealant incessantly, has guaranteed that so the crowded thrust of glue spraying gun 100 is continuous, and enough greatly to extrude fast and effectively this heavy viscous material.So, adopt electronically controlled method to reduce the voltage of motor, make it with very little rotational speed, thereby constantly thrust is applied on fluid sealant, this autoboot function of delivery system 9 has guaranteed that glue spraying gun 100 according to the present invention realized the function of extruding continuously heavy viscous material.
