In order to realize that the shifting lever 11 can swing rightwards and reset, the supporting plate 7 is provided with a yielding groove 26 matched with the shifting lever 11, the yielding groove 26 can prevent the shifting lever 11 from moving leftwards, and meanwhile, the lower end of the shifting lever 11 is provided with a balancing weight 27.
In order to realize that the first rotating shaft 10 rotates clockwise to drive the bull gear 12 to rotate clockwise, and the bull gear 12 cannot rotate anticlockwise, the first rotating shaft 10 is fixedly sleeved with the one-way clutch 28, and the bull gear 12 is sleeved outside the one-way clutch 28; the supporting plate 7 is provided with a friction block 29 pressed on the end surface of the large gear 12, and the friction block 29 causes the large gear 12 to rotate with a certain resistance, so that the rotation of the small gear 14 under the action of the torsion spring 16 does not drive the large gear 12 to rotate counterclockwise.
In order to enable the template to ascend to a certain distance and drive the second rotating shaft 13 to move upwards, the second rotating shaft 13 is provided with a horizontal rod 30 which horizontally faces to the left, a stop lever 31 is arranged on the vertical rod 22 which is closest to the second rotating shaft 13 in the plurality of vertical rods 22, the lower end of the vertical rod 22 corresponds to one flat plate 4, namely, the vertical rod 22 is positioned in the interval between two adjacent rollers 3, and meanwhile, a pressure spring is not sleeved on the vertical rod 22; after the stop lever 31 moves upward along with the vertical rod 22, the stop lever 31 will press the cross rod 30, so that the cross rod 30 drives the second rotating shaft 13 to move upward.
In order to realize that the shifting lever 11 swings left and right to drive the disc 15 to rotate reversely, the disc 15 is provided with a connecting plate 32, the connecting plate 32 is provided with a strip-shaped through groove 33, and the upper end of the shifting lever 11 penetrates through the first rotating shaft 10 and is simultaneously provided with a positioning pin 34 which can be arranged in the through groove 33.
For tolerance and for a more stable switching device, the contact 17 is spaced from the electrode plate 18 when the torsion spring 16 is not under load, and the distance is such that the contact 17 does not contact the electrode plate 18 when the shift lever 11 is slightly swung.
When the die plate feeding device is used, firstly, the switch of the driving device on the power roller way 2 is started, then, the switch on the cutting disc 6 is started simultaneously, then, the left end of the die plate can be inserted between the pressing wheel 8 and the roller 3, and at the moment, the roller 3 can push the die plate to feed towards the right side.
In the device, the cutting disc 6 is positioned at the left side of the electric saw 9, and the deflector rod 11 is positioned between the cutting disc 6 and the electric saw 9; therefore, the template is firstly cut by the cutting discs 6 on the left side and the right side, the front end face and the rear end face of the template are cut off, the width of the template is kept to obtain a designed standard, and meanwhile, the cut section is very neat and has no burr phenomenon after the cutting is finished through the rapid rotating cutting of the cutting discs 6; then the template continues to be fed rightwards, and because the support plate 7 is arranged above the table plate 1 through the rack, when the width of the template is large, in order to avoid the influence of the legs of the rack on the feeding of the template, the legs of the rack should correspond to the positions of the gaps formed after the template is cut as far as possible, so that the cut leftover materials can pass through the front side and the rear side of the legs of the rack.
When the template is fed rightwards and does not touch the shift lever 11, the switch device is in an off state (state I in fig. 4), the shift lever 11 is vertical, the connecting plate 32 is also vertical, and meanwhile, the contact 17 is not in contact with the electrode slice and has a certain distance with the electrode slice; the torsion spring 16, which is mounted between the disc 15 and the pinion 14, is in an unstressed state, so that the motor connected to the cam 5 is not activated at this time, nor is the electric saw 9 activated; the cam 5 is in the state in fig. 2, i.e., the cam 5 does not press the pressing plate 21.
When the template moves rightwards to touch the shift lever 11, the lower end of the shift lever 11 is lower than the template, so that the template moves rightwards against the shift lever 11, and the shift lever 11 rotates anticlockwise. When the shift lever 11 rotates counterclockwise, the shift lever 11 will not drive the large gear 12 to rotate due to the action of the one-way clutch 28, and at the same time, since the upper end of the shift lever 11 is engaged with the through slot 33 on the connecting plate 32 through the positioning pin 34, the disc 15 will rotate clockwise at this time, so that the torsion spring 16 is squeezed, and the small gear 14 will not rotate (at this time, the small gear 14 has a tendency to rotate clockwise, but because the small gear 14 is engaged with the large gear 12, and the large gear 12 cannot twist the large gear 12 due to the action of the friction block 29, the small gear 14 will not rotate); the contact 17 will gradually approach the electrode pad 18; along with the rotation of the shift lever 11, the contact 17 is closer to the electrode plate 18 until the lower end of the shift lever 11 is to be completely positioned above the template, and at the moment, the angle of the shift lever 11 rotates to the maximum; at this time, the contact 17 also contacts the electrode sheet 18 (state two in fig. 4); the electromagnetic clutch mounted on the motor of the cam 5 is energized, the motor is also energized, and the electric saw 9 is also energized.
After the motor and the electromagnetic clutch are electrified, the cam 5 can rotate clockwise, the cam does not jack up the extrusion plate (the cam rotates from a vertically downward position to the maximum radial position, so that the template can be jacked up after the cam rotates 45 degrees), the template can continuously move rightwards, and the right end of the template is completely positioned below the electric drill; then the cam 5 can gradually extrude the extrusion plate 21, so that the extrusion plate 21 drives the flat plate 4 to move upwards, and then when the flat plate 4 is higher than the template, the template can be separated from the power roller way 2 at the moment, and the template stops moving rightwards; at the moment, the width of the saw blade is larger than the distance between the left cutting disk 6 and the right cutting disk 6; therefore, the electric saw 9 cuts the right end of the template, and then the template is lifted up to move the second rotating shaft 13 upwards by the lifting of the vertical rod 22 and the action of the stop lever 31 on the vertical rod 22 and the cross rod 30 on the second rotating shaft 13.
The second rotating shaft 13 moves upwards to drive the small gear 14 to move upwards, at this time, the small gear 14 is not meshed with the large gear 12, and under the action of the torsion spring 16, the small gear 14 rotates clockwise and rotates until the contact 17 does not contact the electrode plate 18 (state three in fig. 4); the cam 5 stops rotating (at the moment, the maximum radial position of the cam 5 does not rotate to the right side, namely the rotating angle of the cam is less than 180 degrees), the electric saw 9 also stops rotating, and when the electromagnetic clutch is also powered off, the cam 5 can freely rotate at the moment and is completely disconnected from the driving motor; at this time, under the action of the downward movement trend of the pressing plate 21, the pressing plate 21 presses the cam 5, and simultaneously, the cam 5 is gradually restored to the initial position under the action of the torsion spring on the installation shaft of the cam 5; at the moment, the template also descends and is in contact with the roller 3 on the power roller way 2, and the template is already positioned below the electric saw 9, so that the saw blade of the electric saw 9 is not in contact with the template, and the template can continuously move rightwards.
During the process that the template is pushed to rise by the cam 5, the rotation angle of the shift lever 11 is further increased, so that the clockwise rotation angle of the contact 17 is increased, and the electrode plate 18 is arc-shaped, so that the switch device is always in a closed state in the process. Then, the motor of the cam 5 is powered off, and in the process of descending the template, the shift lever 11 also rotates clockwise by a small range of angles, so that the disc 15 and the pinion 14 both rotate counterclockwise by a small range of angles, and at this time, because a certain distance is reserved between the contact 17 and the electrode plate 18, even if the contact 17 and the electrode plate 18 rotate clockwise by a small amplitude at the same time, the contact 17 does not contact the electrode plate 18 (state three in fig. 4).
After the process is finished, namely the right end of the template is cut, the template falls down and continues to move rightwards; only the toggle lever 11 will always be above the die plate (the switch device is always in state three in fig. 4).
When the left end of the template is separated from the shift lever 11, the shift lever 11 rotates clockwise under the action of the counterweight 27 and rotates to a vertical state, and the shift lever 11 drives the first rotating shaft 10 to rotate clockwise due to the heavier counterweight 27, and the large gear 12 can be driven to rotate clockwise through the one-way clutch 28 (the friction force of the friction block 29 is not enough to block the rotation of the large gear 12); therefore, at this time, both the pinion 14 and the disc 15 rotate counterclockwise, so that the disc 15 returns to the original position, and the pinion 14 exceeds the original position due to the amplification effect of the large gear 12, so that the contact 17 is in contact with the electrode plate 18 (state four in fig. 4); at the moment, the cam 5 and the electric saw 9 work again, so that the template is jacked up again, and the burr at the left end is cut off by the electric saw 9; at this time, the flat plate 4 corresponding to the vertical rod 22 with the stop lever 31 is pressed to move the vertical rod 22 upward, and the second rotating shaft 13 is moved upward by the stop lever 31 and the cross rod 30; after the second rotating shaft 13 moves upward, the small gear 14 is disengaged from the large gear 12 and moves clockwise by the torsion spring 16 alone, and returns to the initial state (state one in fig. 4).
In the device, the right side of the electric saw 9 is also provided with the power roller bed 2 and the pinch roller 8 with certain lengths, and the flat plate 4, (in other words, the electric saw 9 is not positioned at the rightmost end of the power pipeline, and fig. 2 is only an example) so as to play a certain supporting role on the template when the left end of the template is cut.
In the device, the lower end of the vertical rod 22 closest to the second rotating shaft 13 corresponds to one of the flat plates 4, namely, the lower end is positioned in the interval between two adjacent rollers 3, and meanwhile, the vertical rod 22 is not sleeved with a pressure spring, so that the pressure wheel 8 below the vertical rod 22 can be conveniently positioned above a template when the template enters; meanwhile, after the template is separated from the pinch roller 8, the flat plate 4 below the vertical rod 22 extrudes the vertical rod 22 upwards, so that the second rotating shaft 13 is driven to move upwards.
In the device, under the condition that the cam 5 is operated intermittently all the time, the size of the cam 5 is selected according to the requirement, when the cam 5 presses the extrusion plate 21 upwards, the cam 5 cannot rotate to the other surface, and the number of the cams 5 can be selected according to the requirement.
In this device, since a switching device is designed, when the switching device is manufactured, the portions which the contact 17 and the electrode sheet 18 can contact are both designed to be made of a non-conductive material.
This device has utilized the action characteristic when the template gets into through ingenious design a pivoted switching device, turns into the rotation of first pivot 10 with this characteristic through driving lever 11, then through mutually supporting between the ingenious part, has realized the state when automatic left end and the right-hand member of judging the template get into and break away from, makes the template jack-up through cam 5 then to break away from and feed, realize the cutting.
In this device, the right side of cutting disk 6 has designed the electric saw 9 that is higher than the normal height of placing of template, makes the template at the in-process that normally feeds not contact with electric saw 9, has guaranteed the safety of template and has fed, and when needs cutting, the function is judged through switching device's position simultaneously, realizes automatic lifting template, just in time utilizes the cutting end face cutting of electric saw 9 difference of height to the template at the in-process that rises.
In the device, the design of the switch device is also very ingenious, the rotation relation between the control disc 15 and the pinion 14 is moved by utilizing the simple action of the driving lever 11, the work requirement is ingeniously realized, simultaneously, the number of required parts is small, the matching relation of all parts in the switch device is compact, the switch device is ingenious and practical, the manufacture is convenient, the cost is low, and meanwhile, the size of the whole switch device can be manufactured as small as possible, so that the switch device is convenient to install, use and subsequently replace.
The invention has novel conception, ingenious structure and convenient operation, can realize one-time equal-width edge trimming operation on the template only by continuously filling the template into the device, saves labor, improves the efficiency and particularly improves the safety of the whole operation.
