The friction block 29 being pressed on 12 end face of gear wheel is installed, friction block 29 makes the rotation of gear wheel 12 have certain resistance on fagging 7
Power, therefore pinion gear 14 rotates under the action of torsional spring 16 and not will drive gear wheel 12 and rotate counterclockwise.
After making template rise to certain distance, the second shaft 13 can be driven to move up, second shaft 13
Level is equipped with bar on the nearest vertical bar 22 of distance the second shaft 13 in multiple vertical bars 22 towards left cross bar 30 after upper installation
31, while the lower end of the vertical bar 22 is corresponding with one of plate 4, i.e., in the interval between two neighboring roller 3, simultaneously
Pressure spring is not set on the vertical bar 22;After bar 31 is moved up with vertical bar 22, bar 31 can squeeze cross bar 30, make 30 band of cross bar
Dynamic second shaft 13 moves up.
It drives disk 15 to rotate backward to realize that driving lever 11 swings, connecting plate is installed on the disk 15
32, offer strip through slot 33 on connecting plate 32, the upper end of driving lever 11 be equipped with simultaneously through first rotating shaft 10 can be placed in it is logical
Positioning pin 34 in slot 33.
It is described when torsional spring 16 does not stress in order to which tolerance and switching device are more stable, contact 17 and electrode slice 18
Between there is a certain distance, which can not be such that contact 17 contacts with electrode slice 18 in 11 weak vibrations of driving lever.
The present invention then starts chopping disk 6 simultaneously in use, start the switch of the driving device on power roller-way 2 first
On switch, the left end of template can be then inserted between contact roller 8 and roller 3, roller 3 will push template at this time
It feeds to the right.
Since in the present apparatus, chopping disk 6 is in the left side of electric saw 9, driving lever 11 is between chopping disk 6 and electric saw 9;Therefore
Template can be cut by the chopping disk 6 of the left and right sides first, cut away the rear and front end face of template, while keeping template
The standard that is designed of width, while being cut through the quick rotation of chopping disk 6, the section after the completion of cutting is also very whole
Together, there is no flash phenomenon;And rear pattern plate continuation is fed to the right, since support plate 7 is mounted on by shelf the top of desktop 1, because
This is when template width is larger, in order to avoid the leg of shelf influences the feeding of template, the supporting leg of shelf should as far as possible with template
Gap position after cutting is corresponding, and the leftover pieces after alloing cutting are passed through from the front and rear sides of shelf supporting leg.
It feeding to the right and not being touched between driving lever 11 in template, switching device is in an off state (state one in Fig. 4), this
When driving lever 11 is vertical, connecting plate 32 is also vertical, while contact 17 and electrode slice not in contact with and between the two have it is certain away from
From;The torsional spring 16 being mounted between disk 15 and pinion gear 14 is in unstressed state, therefore is connected on cam 5 at this time
Motor is inactive, and electric saw 9 is also inactive;Cam 5 is in the state in Fig. 2, i.e. cam 5 does not squeeze stripper plate 21.
When template moves right at this time touches driving lever 11, since the lower end of driving lever 11 is lower than template, template
Driving lever 11 can be headed on to move right, rotate counterclockwise driving lever 11.After driving lever 11 rotates counterclockwise, driving lever 11 is due to list at this time
Effect to clutch 28 is not will drive the rotation of gear wheel 12, simultaneously because the upper end of driving lever 11 is by positioning pin 34 and even
Through slot 33 on fishplate bar 32 is cooperated, therefore disk 15 can rotate clockwise at this time, is extruded torsional spring 16, and pinion gear 14
Do not rotate that (pinion gear 14 has the trend that rotates clockwise at this time, but since pinion gear 14 is engaged with gear wheel 12, and gear wheel
12 due to friction block 29 effect, torsional spring 16 can not twist gear wheel 12, therefore pinion gear 14 not can rotate);Therefore contact 17
It can be gradually close to electrode slice 18;With the rotation of driving lever 11, contact 17 can be increasingly closer apart from electrode slice 18, until driving lever
After 11 lower end will be completely in the top of template, the angular turn of driving lever 11 to maximum at this time;Contact 17 can also connect at this time
Contact state two in electrode slice 18(Fig. 4);The electromagnetic clutch being mounted on 5 motor of cam is set to be powered, motor is also powered, simultaneously
Electric saw 9 is also powered.
After motor and electromagnetic clutch are powered, cam 5 can be rotated clockwise at this time, and cam not yet jacks up stripper plate at this time
(cam is started turning to diameter maximum by position straight down, it is therefore desirable to after cam rotates 45 degree, can just be jacked up
Template), therefore template will continue to move right, the right end of template is completely in the lower section of electric drill at this time;Then cam 5 can gradually
Extruding stripper plate 21, make stripper plate 21 drive plate 4 move up, then when plate 4 be higher than template after, template can take off at this time
From power roller-way 2, template stopping moves right;At this time since the width of saw blade is greater than the distance between two chopping disks 6 in left and right;
Therefore under electric saw 9 can cut the right end of template at this time, and rear pattern plate continues the rising that rise can by vertical bar 22 and vertical bar
The effect of bar 31 on 22 and the cross bar 30 in the second shaft 13, moves up the second shaft 13.
Second shaft 13 moves up, and drives pinion gear 14 to move up, pinion gear 14 is not engaged with gear wheel 12 at this time, in torsional spring 16
Under the action of, pinion gear 14 can rotate clockwise, and can rotate to 17 non-contact electrode piece 18(Fig. 4 state three of contact);Make
Cam 5 stops operating (cam 5 is not rotated to diameter maximum to right side at this time, i.e., the rotational angle of cam is less than 180 degree),
Electric saw 9 also stops operating, and after electromagnetic clutch also powers off, cam 5 can be freely rotated at this time, completely de- with driving motor
From connection;At this time under the action of the downward movement tendency of stripper plate 21, stripper plate 21 can squeeze cam 5, while cam 5 also can
Under the action of the torsional spring in 5 installation axle of cam, it is gradually restored to initial position;Template can also decline therewith at this time, and
It is contacted with the roller 3 on power roller-way 2, template has been in the lower section of electric saw 9 at this time, connects the saw blade of electric saw 9 with template
Touching, template can continue to move right.
During above-mentioned template is pushed by cam 5 and rises, the rotational angle of driving lever 11 can further increase, and make to touch
First 17 angles rotated clockwise increase, and electrode slice 18 is arc, therefore during this, switching device can be constantly in closure
State.The motor power-off of subsequent cam 5, during template declines, driving lever 11 can also rotate clockwise small-scale angle,
Make disk 15 and pinion gear 14 that can rotate counterclockwise small-scale angle, at this time due to having between contact 17 and electrode slice 18
Certain spacing, therefore even if the two rotates clockwise by a small margin simultaneously, contact 17 can't be made to touch electrode slice 18(Fig. 4
Middle state three).
After the completion of in the above process, i.e., after the right end of template is cut, template, which is fallen, to be continued to move right;Only driving lever
11 can be constantly in the top of template (switching device is constantly in state three in Fig. 4).
After the left end of template is detached from driving lever 11, driving lever 11 can rotate clockwise under the action of clump weight 27 at this time,
And vertical state is turned to, it, can when driving lever 11 drives first rotating shaft 10 to rotate clockwise since clump weight 27 is heavier
To drive gear wheel 12 to rotate clockwise by one-way clutch 28, (frictional force of friction block 29 is not enough to stop 12 turns of gear wheel
It is dynamic);Therefore pinion gear 14 and disk 15 can rotate counterclockwise at this time, and disk 15 is made to be restored to initial position, and pinion gear
14 due to gear wheel 12 formation amplification, original position can be surmounted, contact 17 is made to contact (shape in Fig. 4 with electrode slice 18
State four);Cam 5 at this time, the task again of electric saw 9, jack up template again, and cut away the flash of left end by electric saw 9;
Plate 4 corresponding with the vertical bar 22 of bar 31 is equipped with can squeeze vertical bar 22 and move up at this time, and pass through 31 He of bar
Cross bar 30 moves up the second shaft 13;After second shaft 13 moves up, pinion gear 14 is detached from gear wheel 12, is individually turning round
It rotates clockwise mobile under the action of spring 16, is restored to initial state (state one in Fig. 4).
In the present apparatus, the right side of electric saw 9 also has the power roller-way 2 and contact roller 8 and plate 4 of certain length, (changes
For it, electric saw 9 is not at the right end of power conduit, and Fig. 2 is only example) in order at the left end of cutting board, can
To play certain supporting role to template.
In the present apparatus, the lower end of the nearest vertical bar 22 of distance the second shaft 13 is corresponding with one of plate 4, that is, is in phase
In interval between adjacent two rollers 3, while pressure spring is not set on the vertical bar 22, therefore when template enters, can be convenient
The contact roller 8 under the vertical bar 22 is set to be in the top of template;After template is departing from the contact roller 8 simultaneously, under the vertical bar 22
The plate 4 of side can squeeze vertical bar 22 upwards, be driven the second shaft 13 and move up.
In the present apparatus, in the case that cam 5 is constantly in intermittent work, the size of cam 5 should be selected as needed
It selects, makes cam 5 when extruding stripper plate 21 is upward, cam 5 will not turn to another side, while the quantity of cam 5 can also
It is multiple to select as needed.
In the present apparatus, due to devising a kind of switching device, when being manufactured to switching device, need to make contact 17 and
The part that electrode slice 18 can contact, is both designed as nonconducting material.
The present apparatus passes through the switching device for cleverly devising a rotation, and motion characteristic when template enters is utilized,
This feature is converted to by driving lever 11 rotation of first rotating shaft 10, it is real then by the mutual cooperation between cleverly part
Show state when left end and the into and out right end of automatization judgement template, then jacks up template by cam 5, and
It is detached from feeding, realizes cutting.
In the present apparatus, the electric saw 9 higher than the normal placing height of template is devised on the right side of chopping disk 6, makes template just
It is not often contacted with electric saw 9 during feeding, ensure that the safety feeding of template, while when needing to cut, filled by switch
The position arbitration functions set realize the lifting template of automation, and positive 9 difference in height of good utilisation electric saw is to template during rising
Carry out cutting ends cutting.
In the present apparatus, the design of switching device, and it is very ingenious, using the simple action of driving lever 11, moved control
The rotation relation of disk 15 and pinion gear 14 cleverly realizes requirements of one's work, while required part is few, switch dress
Each part matching relationship is close in setting, ingenious practical, low in cost convenient for manufacture, while the size of entire switching device
It can manufacture as far as possible small consequently facilitating installing and using and subsequent replacement.
Present inventive concept is novel, and clever structure is easy to operate, it is only necessary to which template is constantly filled into the present apparatus can be realized
To template disposably wide edging operation, manpower is saved, efficiency is improved, especially improves the safety of entire operation
Property.
