Description

Blank cutter is borrowed force driving device

Technical field

This is practical relate to brick and tile enterprise aborning with the supporting a kind of accessory machinery of main frame, is more definitely more particularly for on-stream extruded the continuously base bar of main frame being divided into again to one of them spare and accessory parts of a kind of cutting machine of monolithic adobe or unbaked tile.

Background technology

In slitting, it is push-and-pull steel wire rack slitting or swinging steel wire automatic slicing back and forth that current most of brick field adopts hand merit, the former is oblique line by institute's section, the latter institute section is arc, and six faces of standard adobe bar must be all planes, the base bar face of cutting is that six faces, two large faces wherein more should be concordant, therefore often cuts a base bar and more or less can cause the waste of base head, is generally one or two adobe.

Hand merit slitting is to utilize manpower to move towards rectangular steel wire frame with base bar to win over and push through, every promotion or pull and once can cut off a base bar, because base bar is continuously to extrude from the machine mouth of main frame, and hand merit cannot realize and synchronizeing with base bar in push-and-pull, be that base bar ceaselessly moves forward, in the process that pushes away or draw, steel wire cuts to the left or to the right, making to cause steel wire, initially to enter the base bar of base bar one side short, the base bar that goes out eventually a side is long, according to the speed of base bar walking speed and its cut surface of the length of clipping time, also should be mutually the inclined-plane of certain angle, therefore wanting to become right angle section with base bar trend (length) is impossible realize.

Utilize its acting principle of revolution steel wire automatic slicing as shown in Figure l, rely on base bar slave mouth 10 extrude on formed thrust and base bar support 9 each roller bar be affixed produced friction, the drive roll bar l that promotes one of them diameter maximum rotates, be arranged on the same axle of drive roll on sprocket wheel 2 also do the rotation of equidirectional, be that the following roller bar of base bar its top edge when base bar moves forward is followed base bar and rotated forward with equal speed (under non-slip condition) under the promotion of base bar, in rotation with movable sprocket 2 and chain 12 and be arranged on sprocket wheel 3 on another root axle and gear 4 runnings, by gear 4, drive again dumb bell shaft to cog and 6 do opposite spin, turn middle drive and cut sprocket wheel 7 runnings on shelf 9 moving with sprocket wheel 5 on gear 6 same axises, sprocket wheel 7 drives are cut bow 8 and are done gyration, two undercuts bend and steel wire 11 is installed between 8 tops plays a part to cut off base bar, often rotate a circle its steel wire of drive roll 1 cuts off base bar and once cuts out a base bar 13, after base bar is cut off, by manpower, serve brick cutting machine fast and be convenient to cut steel wire on bow and be unlikely up time and stopped by base bar in revolution, the length of base bar equates completely with the girth (under non-slip condition) of drive roll l.When base bar borrows frictional force to promote drive roll l rotation in reach, cut just initial work of bow like this, cut off again and again thus the base bar of another.

This cutting cutter has saving manpower, base bar length is stable, easy to operate and save the advantages such as power, shortcoming is that cutting section is arcuation but not concordant, its reason is to cut bow to drive cutting steel wire its route in rotation be a circle, thereby it is many and cause waste in next procedure, to cut in base process the useless base in two ends; In addition, revolution steel wire is close to produced frictional force with its base drive roll 1 from base bar with the operation power of cutting bow in reach, because its frictional force is very limited, when base bar moisture content less is that base bar is hard and to produce high hole rate be that its base bar weight of non-bearing hollw article is when lighter, cutting bow running resistance bigger in the situation that, in cutting, with regard to easily causing transversely deforming, destroyed the cross dimensions of wet base, the phenomenon that even can't cut (cannot cut) occurs.

Also has the cutting cutter after a kind of improvement on the basis of the above, owing to having changed, cut the running route of bow steel wire in cutting process, obtained therefrom the cutting section of a vertical level and stopped or greatly reduced the waste of base head, increased in addition one by small machine and fast roller and drive and belt common form send strip device, thereby by the base bar cutting off at every turn fast and automatically serve brick cutting machine, saved thus the trouble that manpower send bar.It is still not poor that its incision principle and the former turn round steel wire cutting cutter, its structure and acting process be as shown in Figure 2: the base bar 11 that slave mouth 20 is extruded is mutually close to and moves forward with the adhesive tape 12 being arranged in frame 1 under gravity, owing to being close to formed frictional force, by base bar, promote adhesive tape 12 run-in synchronisms, adhesive tape 12 drives drive rolls, and wherein the gear 4 of one end is intermeshing with the gear 13 on dumb bell shaft, thereby on-stream drive is arranged on sprocket wheel 14 and chain 15 and the upper sprocket wheel 8 on dumb bell shaft and cuts bow and do running in the other direction, owing to cutting bow and steel wire (not shown) is installed between 9 in left and right two, steel wire two ends are buckled on the supporting-point that can be shifted up and down, after supporting-point, there is retractable spring 18 position, anteposition has trundle 16 on track 10, down and forward to slide, its taxi circuit obtains a concordant base bar section with technological requirement and is as the criterion, on-streamly by steel wire, follow and cut bow and turn round again and again and do work.Fast roller 6 centers are with to cut bow spindle central equally matched apart from the size of L and the institute base bar length of cutting, base bar is cut off rear travel switch (not shown) and is opened and starts thus not motor 5 and drive fast roller 6 rotations by V belt 16, in rotation, drive flat tape 17 runnings that separate with back segment, thus cut base bar 19 on adhesive tape served to brick cutting machine fast and accept next procedure---cut base.

Its shortcoming also has the following disadvantages except cutting dynamics is very limited: in order to drive, cut bow reverse direction operation along its cutting technique, it is gear 4 and gear 13 that two gears of main quilt must be set, in order to make to cut bow, be with even cutting steel wire normally to do work, two sprocket wheels of main quilt and chain must be installed, and gear and sprocket wheel can not be installed on room, must there be axle and corresponding bearing and bearing block to support, cause thus manufacturing cost higher.

Although current brick and tile enterprise cutting cutter has varied its configurations, its merit principle and above-mentioned similar, also has and a kind ofly by air pressure, impels air pump piston to stretch to cut, due to complex structure not only cost height but also keep in repair difficulty.

In cutting base, most producers adopt push-down blank cutter, although have of all kinds, but acting principle is consistent substantially, its structure and acting process be as shown in Figure 3 and Figure 4: by motor or internal combustion engine, drive belt wheel 11 runnings on high speed shaft in rotation, the driving gear being arranged on high speed shaft is that pinion 12 is that gear wheel 13 is intermeshing with the driven gear on slow-speed shaft, thereby drive slow-speed shaft running to realize thus the object of first deceleration, pinion 14 on slow-speed shaft meshes with the gear wheel 15 on power transmission shaft, reach thus the object of deceleration again, in addition the driving pulley (not shown) on motor is less than the passive belt wheel 11 on high speed shaft, make it be arranged on the speed ceaselessly running continuously that the gear wheel on power transmission shaft turns with 30-40 per minute, because its internal diameter is provided with journal bearing or sliding bearing 16, thereby during not work done just idle running not drive power transmission shaft, again owing in a certain position of this gear, jaw clutch 5 being installed half, during acting, coordinate transmission with coaxial and adjacent half jaw clutch 4, between the two, being equipped with control lever 2 is connected with the swingle 17 of rear position, tail end at swingle 17 is provided with pedal 1, existence because of spring 3 while not doing work is spaced from each other left and right two and

half formula clutches

4 and 5 by control lever, when needs actings (cutting base), by employee's lower pedal 1 that tramps with one's feet, impel swingle 17 to rotate, thus control lever 2 is pulled out from clutch, make to cause half jaw clutch 4 and be close to (engaging) with adjacent half clutch 5 immediately under the pressure of rear position spring 6, drive thus power transmission shaft 18 rotations, in rotation, band is mounted on each eccentric wheel 8 rotations of two ends of same axis, the a certain position of side that is arranged on respectively each eccentric wheel 8 of both sides due to two of left and right connecting rod 10 is non-central, thereby eccentric wheel drives move front and back back and forth 10 whiles of connecting rod that two of left and right level is installed in rotation, owing to being provided with between both sides connecting rod 10 front ends and the rectangular laterally also horizontal push pedal 19 of connecting rod, before push pedal 19 is every, pushes away once base bar is pushed through to steel wire 20, thereby by many steel wires, whole piece base bar is divided into polylith adobe, because the rear position of control lever 2 is provided with spring 3, when control lever is backed out, spring 3 is compressed, when employee loosens pedal 1 because the pressure of spring is eliminated and protracts immediately, impelling thus control lever to reset separates clutch again, thereby often back out and the power transmission shaft of resetting the once base bar of cutting of i.e. acting that only circles.

Above-mentioned blank cutter not only must a supporting motor or internal combustion engine as cutting base power (sending bar power outside), and need an employee often to cut a base bar must to step on pedal one time, after being pushed over steel wire at every turn and being divided into polylith adobe or labour intensity is large by manually carrying on rickshaw, or change into by rickshaw back to front from brick cutting machine by and equipment investment is many and place takies wide.Next is that one of every cutting or two base bars must must be polished in push pedal and brick cutting machine face, also has the more complicated high deficiency of manufacturing cost that causes of structure.

summary of the invention

The utility model is for solving above-mentioned deficiency, aim to provide a kind of simple in structure, cheap, cutting section vertical level, size is accurate, length is adjustable arbitrarily, soft or hard is extruded to all competent a kind of disconnected bars and divide base equipment, by following technical scheme, is achieved.

The base bar of extruding according to the on-stream slave mouth of extruder is for continuously shifting forward and exist this theorem of certain thrust, the upper installation of the bearing support (frame) of load base bar can before and after displacement front be cutting rack after be baffle plate frame, the two is implicative of each other by cotton rope or stay each other, reach acting is the thrust by means of base bar, retreating resets be by means of be arranged on its left and right sides of cutting rack up and down its following travelling wheel of slide bar low track after front height of slippage under the effect of deadweight, also return backward downwards, or towed back to the cotton rope of counterweight or the pulling force of extension spring or elastic cord by means of back, also can obtain same effect.The displacement of every front and back is once cut a base bar and is started power base bar is sent to next procedure fast---and on brick cutting machine, accept to cut base, the base bar that is about to a certain length is divided into some adobes again.Details are as follows with acting principle for its structure.

The baffle plate of a rotatable certain angle is installed on baffle plate frame, its effect is for accepting base bar in the thrust of reach, by baffle plate, block the outlet of base bar, by base bar be initiatively baffle plate be passive the two synchronously move forward, on cutting rack, install one can oscilaltion certain size cutting knife, a low early and high after movable track (can rotate to an angle up and down) is respectively installed respectively in the left and right sides of walking upper its back segment certain length that journey route is corresponding with cutting knife, its leading portion is horizontal track, track role is that restriction cutting knife send decline size and the decrease speed in bar process in cutting process neutralization.Baffle plate be take the point of rotation and as boundary, is divided into upper-lower section two parts, and epimere weight overweights hypomere, when hypomere (lower part) overweights front in epimere back during in vertical configuration, and turn forward and strut that can swing certain size props up the back of both sides, epimere top by top, its effect is that the base bar extruded when slave mouth can not rotate due to the effect of strut while being affixed and promoting baffle plate reach with baffle plate hypomere back in reach, thereby driving baffle plate frame company and cutting rack to do to synchronize with base bar shifts forward, in displacement, implement the cutting to base bar from top to bottom, can obtain thus the otch section of a vertical level, as long as increase or reduce the distance of baffle plate and cutting knife by technological requirement, just can obtain the base bar of an ideal length.

Base bar in reach before being affixed with baffle plate, the distance of baffle plate and cutting knife for recently, minimum range size with last time base bar be cut to that next base bar is initial and be affixed at this moment with baffle plate between the journey of walking of interior its base bar extrude length; During initial cut, the distance of its baffle plate and cutting knife is for farthest, and maximum distance dimension is as the criterion with the fixed base bar length of technological requirement.

Base bar is that active, baffle plate are passive company and the reach of baffle plate frame, and during initial movable, owing to involving, the cotton rope of baffle plate frame with cutting rack is not tightened up or top, stay rear end does not recline mutually with cutting rack, thereby can not drive cutting rack to be shifted.The lifting device of cutting knife is that method for improving can be that the upper both sides handle of a knife bar cover of cutting knife has spring by its jack-up, or by extension spring or with the cotton rope of counterweight, it is up drawn, or be that up one of laborsaving lever is lifted by rotary lever, now the next edge of a knife of cutting knife forms space and makes way for base bar and pass through a little more than base bar, baffle plate frame then drives cutting rack to synchronize and be shifted with base bar in continuing reach, because cutting knife is upper, there is existence low before rear height and movable track that can original position rotate to an angle, cutting knife is subject to the restriction of track and declines, in decline, base bar is from the superficial to the deep implemented to cut apart from top to bottom.

By track low before rear height be mounted to movable can rotate to an angle up and down its objective is when cutting knife do work complete rising retreating reset from track top by time can depress track rear end and not be blocked and surmounted smoothly, after surmounting, reach to rear stop.Its track take the point of rotation as boundary, be divided into before and after two parts, the low not straight line of rear end head height front end, and leading portion overweights back segment, front and back are respectively for straight line is combined into a downward obtuse angle shape, its anglec of rotation is controlled by each catch of the upper front and back of the point of rotation, after when standing, catch reclines mutually with back segment, front catch and leading portion are separated by a distance, the number of distance can be smoothly by being as the criterion in return with cutting knife, the thickness that is back segment track adds a small amount of gap, cutting knife its upper top travelling wheel and track in reach are affixed below, after surmounting the track point of rotation, under top power effect up, impel on track leading portion and move with catch and be close to, although like this before and after track two sections be an obtuse angle shape below, and the journey of walking of cutting knife to remain low before rear height be a straight line, low obtuse angle shape track surmounted rear height after cutting knife cuts off base bar completely before, its track automatically resets under front heavy rear light effect.To be advanced to cutting complete from initial, its baffle plate frame and cutting rack travelling wheel and be arranged on slide bar following travelling wheel on cutting rack all at horizontal track superior displacement, thus resistance is very micro-.

After base bar is completely severed, slide bar following travelling wheel is about to walk the high rear low slope track of going forward, the initial horizontal track that enters of its cutting knife top travelling wheel does not stretch upwards or promotes seldom. and the strut of being meanwhile close to position behind baffle plate top before it is installed in stroke that barrel roll on bearing support blocks and no longer reach throwing off immediately with baffle plate, also can then by pine, become tightly strut is pulled open by the cotton rope being arranged between frame and strut top, the upper back of its baffle plate is owing to there is no support, lower under heavy and front effect heavy after light, take at once light the point of rotation as boundary's epimere backward and downward, hypomere is also upwards toppled over forward, in toppling over, rotate to an angle and make the next formation space make way for base bar to pass through, baffle plate frame is now standing shape, base bar has little by little been depressed slightly forward the floating idler roller by spring jack-up, thereby started small machine (the next travel switch that is provided with of carrying roller), certainly also can select sensor is optoelectronic switch and cancel floating idler roller, on anteposition transverse axis due to driven by motor, there is cotton rope to be connected with rear position cutting rack, the rotation of transverse axis by cotton rope one circle another enclose the land to be wrapped on axle make it by long shortening, form pulling force, thereby cutting rack company and cutting knife are drawn forward fast, the base bar that its walking speed is far extruded faster than slave mouth, thus the base bar having cut off is pushed on brick cutting machine in front fast forward, accept next process---cut base, the base bar that is about to a certain length is divided into some adobes again, be not generally tens to twenties not etc.

Its acting process is: due to the left side at baffle plate frame or the right or left and right bilateral installed laterally can in the tongue of a small amount of size of external extension, tongue rear end cover has spring, inside its back of a small amount of length, top of front end is a hypotenuse, with triangle, explain orally its adjacent side front, outside, hypotenuse is in rear (with base bar trend minute front and back) for opposite side; Baffle plate epimere on baffle plate frame is that a concave shape is sky, and the width in its space is wider than cutting knife; And by an extension spring or elastic cord to be laterally connected in the left and right of plate washer frame back.Under the effect of power cutting rack in shifting forward fast, enter baffle plate concave indentation and surmount its point of rotation and baffle plate frame on tongue and extension spring or elastic cord, tongue one moves back one and stretches cutting rack is blocked, and impels extension spring or elastic cord by directly becoming curved and by short elongated and become tight by pine.The cutting knife meanwhile being moved forward fast due to base bar is seen off, and the floating idler roller being depressed resets and power-off at the extensional process float downward of the next spring.The travelling wheel that is now arranged on upper its transverse axis two, two cutting knifes handle bar top of cutting knife has surmounted the front top of horizontal track terminal, by the lift of lifting device, impel the cutting knife reset of rising immediately, to be the upper left and right of cutting knife travelling wheel surmount track below by track in reach rises to bit space on track and retreats with cutoff knife rack, after closing in retreating, low rotating track tail end top is affixed during stop and before rear height, in the effect of gravity, press down lower railway tail end and surmounted, track tail end is because having eliminated the pressure reset of rising.Again because motor not only can be clockwise but also can reverse, after power-off top, its slide bar lower end travelling wheel under Action of Gravity Field along track low after front height immediately backward and slippage downwards, in slippage, be wrapped in the cotton rope drive motor reversion on transverse axis, the company's of being with cutting rack and baffle plate frame retreat reset thus, while covering in slope track initial step flat track in slide bar lower end travelling wheel moves after downslide, because the corresponding positions in frame is provided with standing angle plate, tongue follow baffle plate frame after then space and the plate of its rear end meet in moving, plate inserts in space, tongue rear end, because the effect of angle impels tongue to retreat, after stopping, moving by baffle plate frame now.The spinning reduction of baffle plate can by wherein one be the stay cord that hangs over frame anteposition, or by being arranged on the low early and high after ramp of corresponding positions, frame both sides, need only travelling wheel be installed in baffle plate epimere left and right and just can realize along ramp backward and up.Former being elongated with the extension spring of stretch bending or elastic cord because backing out of tongue eliminated restriction connects cutting rack as archery and cutting knife pushes backward, makes it reach reset position, completes an acting circulation.

From being affixed and promoting after base bar front end top and baffle plate baffle plate connecting and baffle plate frame shifts forward, to cutting rack band, connect cutting knife and retreat that to reset be only the overall process of once doing work, at this moment between in complete disconnection and the propelling movement of a base bar, repeat to realize continuous production.

More simple way is that baffle plate frame and cutting rack are mounted to an integral body (cutter sweep), and in acting overall process, the distance of baffle plate and cutting knife remains unchanged; The track whole process being affixed with slide bar following travelling wheel has not all had a horizontal segment for low after front height.After base bar is completely severed, cutting knife no longer moves forward, and has cancelled thus the horizontal track of the upper former leading portion of cutting knife.As long as select endless belt to wrap up by being cut off its next several carrying rollers of being pressed of base bar, and larger carrying roller before or after one of them is wherein installed to drive on an axle, by belt or chain direct or indirect with motor shaft upper driving wheel (through slowing down), be connected, under the effect of power, impel endless belt fast turn-around (prior art), thus base bar is sent forward fast.

For realize from base bar be chopped to base bar be sent before at this moment between internal cutting device to stand fast be transfixion, because it is irreducible having its baffle plate of existence of base bar, and at the monolateral or left and right bilateral installation lever toe dog of the left or right of cutter sweep (baffle plate frame and cutting rack), its interlude is a point of rotation, following backward top is forward skewed, and install a travelling wheel additional in hypomere top, by an extension spring by travelling wheel forward with toward drop-down, travelling wheel is followed cutter sweep and is synchronously done front and back slippage on the corresponding track of bearing support dual-side, the half of circle of inverted arc shape pit is set on the track of front stop corresponding positions, after being thrown off, baffle plate back strut can not retreat due to the effect of toe dog thus, and in the back of baffle plate epimere, a rotatable roller is installed, baffle plate in toppling on its roller and base bar plane be affixed and stop toppling over, when base bar by after seeing off owing to not had its baffle plate of load of base bar to continue again to rotate to an angle, by about both sides, baffle plate top, stretch out and a little depress toe dog epimere and impel it to rotate to an angle, in rotation, top down and forward, following is deviate from backward and up and is ineffective from pit, cutter sweep is owing to there being the existence of low orbit after its next front height to retreat reset under the drive of lift slide bar.

By track low after front height and slide bar following travelling wheel, being affixed its effect is to impel the cutter sweep after acting to retreat in time reset, also can be that to hang in frame one be to hang over the pulling force that extension spring on cutter sweep or elastic cord be elongated in reach can realize the object of reset equally by means of one, its weak point is drawn to such an extent that the resistance of more microscler one-tenth is larger, otherwise or by tail end, with the cotton rope of counterweight, by pulley counterweight in reach, rise to decline and realize cutter sweep and retreat reset, just can reach in reach is balanced resistance from start to finish.

Send back that bar walks its brick cutting machine of the rectangular the place ahead of journey route to install one with slitting can be forward and down, again can be backward and the thrust frame of a rotatable certain angle of up returning, the left and right, front of thrust frame is respectively each vertical slide bar, the front of two vertical slide bars is positioned on brick cutting machine face Wei mono-Transverse to the push pedal of side formula, roller is installed up and down in push pedal back and vertical slide bar is affixed, the vertical slide bar back of same level line is provided with equally roller and is affixed with it, be that the brick cutting machine face left and right sides has upper and lower front and back roller that vertical slide bar is clipped in wherein, vertical slide bar back interconnects thrust frame of common composition with upper and lower two swingles in rear position respectively up and down, its junction is rotatable for being slidably matched, its push pedal and upper and lower front and back roller are done horizontal shifting with it in the upper and lower of vertical slide bar and front and back displacement, push pedal is affixed with base bar back in reach, thus last process being served to base bar on brick cutting machine face pushes through and is arranged on some steel wires in front and is divided into the adobe of a piece monolithic.

In push pedal frame anteposition, select support plate to install one additional and can rotate up and down the pressing plate of a small amount of angle, being connected to of pressing back-end and support plate be slidably matched rotatably, its point of rotation is positioned at pressing back-end head (with base bar trend minute front and back), the pressing plate left and right sides is separately installed with travelling wheel straight rail road and moves after with baffle plate frame, pressing plate is low slope after a front height below, in reach, its hypotenuse is pressed in a velamen and is clipped between the upper and lower several rollers in left and right up and down on its left side pulley of vertical traveller of slippage, the gradient of hypotenuse and length are as the criterion can realize vertical traveller being pressed down to put in place in reach, as long as select cotton rope and turn by several pulleys that the two involves each other by the front of the thrust frame of above-mentioned rotatable certain angle and vertical traveller, vertical traveller heavy burden pressurized move down middle by cotton rope toward drop-down, just drive thrust frame and be shifted forward and downwards, as long as in the next counterweight that places in the back of thrust frame, counterweight role be take the point of rotation as boundary its swingle lower end and Chong Yu upper end, rear end and front end, in retreating, pressing plate because pressure disappears, vertical traveller is resetted along with thrust frame rises by the pulling force of cotton rope, its reason be thrust frame due to after the disappearing in of pulling force with under overweight before with upper condition under up and backward reset, cotton rope is now by backward and pull down, change into forward and upwards and draw, be that thrust frame is up moved vertical traveller to position in process up and backward, wait for acting next time.

Its acting principle is, it is the existing thrust of base bar by means of extruding from rear position its machine mouth of extruder that push pedal frame shifts forward, it is connected to the support plate stretching out due to pressing back-end top and push pedal frame front and is slidably matched and can rotates up and down, junction is the point of rotation, according to lever principle, its pressing plate below with vertical traveller on the pulley of pulley joint place its barrel shift in pressing plate reach apart from the pressing back-end head point of rotation from as far as closely, its pressure can be several times to tens times more than of the own weight of pressing plate according to distance difference, because the pressing back-end point of rotation or point of rotation back have travelling wheel and top track to be affixed, down its rear end is up as boundary's pressing plate front end to take compression point (the pulley joint place on the next hypotenuse of pressing plate and vertical traveller), up formed counter-pressure is born by getting on the right track, being the point of rotation or the travelling wheel that approaches point of rotation position pastes tightlyer with getting on the right track, counter-pressure drops on and on track, equals to drop on large ground, as long as track does not leave the earth when being subject to counter-pressure, and this point is easy to accomplish, need only strengthen the weight of its support of attachment rail or be connected with the earth by foundation bolt just to become.

In sum, specific practice of the present utility model be the anteposition of bearing support plane installed can before and after the baffle plate frame of displacement, with in position thereafter, installed can before and after the cutting rack of displacement, the two is together to form cutter sweep, by cotton rope or stay, be implicative of each other each other, and the baffle plate that can original position rotates to an angle is installed on baffle plate frame and at its monolateral or bilateral tongue or toe dog of being provided with, on cutting rack, be provided with can oscilaltion certain size cutting knife, on the bearing support of the upper both sides of cutting knife, be provided with and low early and high afterly can rotate up and down the track of a small amount of angle, be used for impelling cutting knife to implement cutting downwards in reach, the upper back of its baffle plate be provided with strut that top can swing certain size for baffle plate the location in reach, bearing support anteposition is provided with the barrel roll of backing out strut, or be with a cotton rope, will involve each other between bearing support and strut top by being arranged on frame, in strut reach, its cotton rope is become tightly strut is drawn and moved back by pine.It is to have cotton rope to be implicative of each other between bearing support anteposition and baffle plate top that system hangs over frame, in moving after baffle plate, its cotton rope is become and is tightly made baffle plate reversion reset by pine, or in its low early and high after ramp of installation, left and right of corresponding positions of frame, be used for replacing cotton rope and realize baffle plate return, bearing support is that after frame, position is provided with for backing out the plate of tongue.The slide bar of slippage is up and down installed on cutter sweep, corresponding with slide bar the next be that track low after a front height is for the return of cutter sweep, or be to hang on the bearing support that other end system on cutter sweep hangs over rear position as being implicative of each other by extension spring or one of elastic cord, or the cotton rope that hangs with counterweight by tail end head system is hung on cutter sweep for replacing slide bar and lower Bit Track and tongue and the skewer plate corresponding with slide bar by its front system of pulley, near and while selecting cutting knife to send bar when far away when the distance of baffle plate frame and cutting rack is in displacement, hanging with cotton rope on by the little axle of motor-operated anteposition (transverse axis) involves mutually with the cutting rack of rear position, and by a horizontal elastic cord or extension spring, involve mutually for being hit by a bullet and pushing away cutting rack retreating return between its left and right sides, the back of baffle plate frame.

In the frame of the back of brick cutting machine, installing one can be forward and down, thrust frame that again can be up and backward, and the pressing plate that can rotate slightly up and down a small amount of angle at its front end of its front and back displacement push pedal frame anteposition installation of cutting cutter is connected as a single entity with it, pressing plate is affixed for the pulley on the vertical traveller of slope low after front height and original position lifting below, and selecting two is respectively that the cotton rope that hangs over thrust frame front and vertical traveller involves the two each other; It is that pressing plate front end can rotate slightly up and down that being connected to of pressing back-end and push pedal frame support plate in front is slidably matched; Vertical slide bar and vertical traveller are sandwiched in respectively between upper and lower each roller in front and back.

With reference to before Fig. 8 for after baffle plate frame 4, for cutting rack 5, the two is implicative of each other by means of the upper and lower stay 37 of left and right bilateral (only illustrating one-sided in figure) each other, its stay is fixed on baffle plate frame and can adjusts its length according to technological requirement with each nut 38 of front and back, stay rear end is passed from the hole of cutting rack, baffle plate frame in reach then stay tail end major part and cutting rack hole be close to and can not pass through, thereby the company's of drive cutting rack synchronously shifts forward.

With reference to Fig. 9 and Figure 10, the next centre is provided with blade 39, its blade of cutting knife in Fig. 8 is the next has also installed a cutting steel wire 40 additional, the upper support of cutting knife left and right is provided with travelling wheel 29, upper center for ease of promoting by laborsaving lever in Fig. 7 is provided with pulley 41, in Fig. 8, by the cotton rope 43 with counterweight 42, pass through pulley 44 for promoting, and roller 45 is installed up and down for reducing the friction in lifting in its left and right, with the frictional resistance of cutting rack left and right sides vertical rail (not shown).

The interlude point of rotation 46 with reference to Figure 11 and the laborsaving lever of Fig. 9 is arranged on (not shown) on cutting rack, front end is positioned at limit under the upper positive middle pulley 41 of cutting knife to be close to it, and the point of rotation of take overweights at front end as boundary and under the condition of rear end, pulley connected and cutting knife upwards promotes certain size.

With reference to Figure 12, its the next plate face 47 of baffle plate is for accepting the thrust of base bar in reach, support upper top in left and right is provided with runner 48 for reducing the friction with strut, with point of rotation 31Wei circle top heavy and rear heavy front light, after backing out, upper end backward and downwards, lower end rotates formula forward and upwards and topple over to be convenient to strut (not shown).

With reference to Figure 13 cutting knife left and right sides column 49, in front and back, can between the roller 50 of original position rotation, do displacement up and down up and down.

With reference to Figure 14 baffle plate 6 its left-right rotary turning points 31, be arranged on baffle plate frame 4, its the next intermediate plate face 47 is affixed with base bar 2 sections, base bar is by 10 loads of carrying roller, by base bar promotion baffle plate company and baffle plate frame, together moved forward, the left and right of baffle plate frame be separately installed with can in the tongue 16 of external extension, tongue tail end has space 22, its effect is to insert in space 22 and impel it to retreat (outwards backing out) when retreating the plate (not shown) that is arranged on relevant position, frame both sides while putting in place, the connection baffle plate frame left and right sides is tightened up the curved elastic cord of elongated change 51 and like that cutting rack (not shown) is pushed and put in place backward for back out time image archery when tongue.

Referring to Figure 15 Figure 20, brick cutting machine 54 foremost transversely arranged some steel wires 52 for cutting apart reach base bar 53, frame 63 left and right sides, brick cutting machine back be provided with in thrust frame 58(figure, only illustrate one-sided), thrust frame be take the point of rotation in rotation, and as boundary, its upper end is forward and down, impel thus the vertical slide bar 57 of interlude between front and back roller 61 down and toward anterior displacement, in displacement, promote push pedal 56 and base bar 53 is pushed through to front-seat many steel wires 52 be divided into polylith adobe.Its acting principle is: being arranged on that its push pedal frame of cutting cutter support plate in front 75 is slidably matched with being connected to of pressing plate 70 is the rotatable point of rotation 74 that is decided to be, the existing thrust of the base bar (not shown) extruded by back slave mouth promotes that push pedal frame connects and support plate 75 and pressing plate 70 are done and synchronizeed reach, the next hypotenuse at reach center platen is pressed on the pulley 67 on vertical traveller 65 left sides, stage casing, impel thus the down slippage in the middle of left and right sides roller 66 of vertical traveller 65, now before pressing plate, travelling wheel 72 is slightly thrown off with track 68, gravity is dropped on the next pulley 67 entirely, owing to there being cotton rope 59 to involve mutually with flat pulley 55 and vertical slide bar 57 lower end elbows by several side formula pulleys 60, thereby by vertical slide bar toward drop-down, impel thus vertical slide bar band to connect thrust frame 58 down and forward rotation displacement make to push away before push pedal 56, in front pushing away, impel base bar to surmount steel wire 52 and be divided into the adobe of a piece monolithic, complete an acting circulation.

In thrust frame 58 its upper end processes forward and down in rotation, complete while pushing away base action, pressing plate 70 is now still in reach (not arriving front stop), initial the entering in the groove 73 of pressing plate the right of pulley 67 on vertical traveller 65, pressure now disappears, travelling wheel 72 straight rail road 68 reaches below of pressing plate left and right, after pressure disappears, its vertical slide bar 57 upwards and is backward resetted with thrust frame by the pulling force of cotton rope 59 no longer under the effect of counterweight 64, in rising, by cotton rope, the vertical traveller 65 that is arranged in groove 73 is up drawn and makes it together increase thereupon, after putting in place, rising waits for that pressing plate retreats, meanwhile, after pressing plate, the push pedal frame of position and cutting rack are return completing after to base bar cutting and by slitting frame, reach is served brick cutting machine by base bar fast backward, together retreat reset returning the company's of picking up pressing plate, pulley 67 its flat pulley 80 crossheading ditches 81 in front on the vertical traveller left side are now forward one moving one quiet, (pressing plate retreats as moving, vertical traveller is quiet), surmounting the rotatable opening-closing plate 71 of top throws off with pressing plate, wait for acting next time.

Pressing plate 70 its gravity in reach drops on vertical traveller 65 entirely, by cotton rope 59 by upper and lower front and back totally four side formula pulleys 60 involve mutually with a flat pulley 55 and vertical slide bar 57 its top, lower ends hooks 83, vertical traveller in being subject to drops by vertical slide bar toward drop-down, pressing plate in reach its compression point with pulley 67 be affixed place apart from the point of rotation 74 from as far as closely, as long as add the distance of large plate front end top and the back point of rotation.Different from the distance of the point of rotation according to compression point under the constant condition of weight, its pressure can be several times to tens times or the more of own weight of pressing plate, the formed counter-pressure of pressure impels the travelling wheel 82 being installed in the point of rotation to paste tightlyer with top track 69, because travelling wheel 82 is barrel shift in the following slippage of track 69, although for being close to increased resistance few, by the existing thrust of the base bar of extruding from back, promote baffle plate frame even and pressing plate reach, pressing plate moves forward, and needed power just equals to promote and pressing plate identical weight is stopped the object with wheel in orbit, and pressing plate gives vertical traveller institute applied pressure much larger than the pressing plate required thrust that moves forward.
