blades

62 and 63.

A workpiece holding block 64 is provided on the cutting blade mounting block 61 via an elastic member 65, the workpiece holding block 64 being located in the space between the left side cutting blade 62 and the right side cutting blade 63. In the present embodiment, the elastic member 65 has a spring structure.

As described above, the left cutting blade 62 and the right cutting blade 63 form a gap therebetween, and since the gap is constant, the fixed-length division of the workpiece 70 is also achieved. The elevation driving unit 50 drives the cutting blade attachment block 61 to descend, and the left cutting blade 62 and the right cutting blade 63 also descend to cut the workpiece 70 on the work plane 21 of the base 20, thereby dividing the workpiece 70 into fixed lengths.

As shown in fig. 3 and 4, it should be noted that the workpiece pressing block 64 is disposed on the cutting blade mounting block 61 through the elastic member 65, and in the original state, the workpiece pressing block 64 is not located on the same horizontal plane as the left side cutting blade 62 and the right side cutting blade 63 (the left side cutting blade 62 and the right side cutting blade 63 are located on the same horizontal plane), and the workpiece pressing block 64 is closer to the working plane 21 of the base 20, so that during the lowering of the cutting blade mounting block 61, the workpiece pressing block 64 will first contact the workpiece 70, and the workpiece pressing block 64 stably presses the workpiece 70 on the working plane 21 of the base 20 to prevent the rebound phenomenon. The cutter blade mounting block 61 is further lowered, the workpiece holding block 64 is kept in contact with the workpiece 70 by the elastic member 65, and the left side cutter blade 62 and the right side cutter blade 63 are further lowered, so that the fixed-length division of the workpiece 70 is realized after the left side cutter blade 62 and the right side cutter blade 63 are in contact with the workpiece 70. When the cutting blade mounting block 61 is raised in the reverse direction, the respective components are reset to the original state.

As shown in fig. 3 and 4, in the present embodiment, the cutting blade mounting block 61 is provided with an anti-shift guide post 61a, and the workpiece pressing block 64 is provided with an anti-shift guide groove (not shown) that cooperates with the anti-shift guide post 61a, so that the stability of the workpiece pressing block 64 can be improved, and the workpiece pressing block 64 is prevented from shifting when pressing the workpiece 70.

As shown in fig. 1, in the present invention, a moving roller 22 and a handle structure 23 are provided on a base 20. By providing the moving roller 22 and the handle structure 23 on the base 20, it is possible to move the base 20 to a designated area very conveniently.

The cutting device 10 capable of dividing a workpiece into fixed lengths further includes a safety driving device 80 (shown in fig. 1 and 5) mounted on the base 20, wherein the safety driving device 80 is electrically connected to the lifting driving portion 50. By providing the safety driving device 80, the elevation driving part 50 can be controlled more safely, and the elevation driving part 50 can be prevented from being triggered by mistake.

As shown in fig. 6 and 7, specifically, the safety driving device 80 includes: a fixed seat 100, a sliding rocker 200, and two buttons 300.

The fixing base 100 is fixed on the working plane 21 of the base 20.

As shown in fig. 6 and 7, the fixing base 100 has a receiving cavity 110, and the sliding rocker 200 is received in the receiving cavity 110; a sliding guide groove 111 (as shown in fig. 7) is formed at the bottom of the accommodating chamber 110, a sliding guide block 210 is disposed at the middle of the sliding rocker 200, and the sliding rocker 200 is rotatably and slidably disposed in the sliding guide groove 111 through the sliding guide block 210; a return spring 400 is further disposed in the accommodating chamber 110, and the return spring 400 is used for sliding the sliding-type rocker 200 along the sliding-type guide groove 111. Here, it is explained that the sliding-type seesaw 200 is rotatably and slidably provided in the sliding-guide groove 111 by the sliding-guide block 210, and it should be understood that the sliding-type seesaw 200 can be formed in a "seesaw" motion in which one end of the sliding-type seesaw 200 is lowered and the other end is raised during the rotation; the "slidable" should be understood that the sliding type rocker 200 is linearly reciprocated along the groove direction of the slide guide groove 111.

As shown in fig. 6 and 7, the bottom of the accommodating cavity 110 is further formed with two blocking grooves 112, the two blocking grooves 112 are respectively located at two sides of the sliding guide groove 111, and two ends of the sliding rocker 200 are respectively formed with blocking protrusions 220 that are matched with the two blocking grooves 112.

As shown in fig. 6 and 7, two buttons 300 are disposed on the fixing base 100 and located outside the accommodating cavity 110, and the two buttons 300 respectively correspond to the blocking protrusions 220 at two ends of the sliding rocker 200; the blocking protrusion 220 has an inclined surface 221, and the button 300 has an expansion link 310 (as shown in fig. 8 and 9), the expansion link 310 penetrates through the cavity wall of the accommodating cavity 110 and is pressed against the inclined surface 221 of the blocking protrusion 220 by an expansion spring 320 (as shown in fig. 9).

The sliding rocker 200 is provided with a trigger lever 500 (as shown in fig. 7), the lifting driving part 50 has a contact point, and the trigger lever 500 is contacted with or separated from the contact point.

The following describes a method of using the safety drive device 80 and its operation principle:

in the original state, the trigger lever 500 is separated from the contact of the elevation driving part 50, and in the separated state, the elevation driving part 50 is not triggered to be driven, so that the device does not work;

in order to bring the trigger lever 500 into contact with the contact of the elevation driving part 50, the left and right hands of the operator are required to simultaneously press the two buttons 300 (shown in fig. 10); when the two buttons 300 are pressed simultaneously, the both ends of the sliding type seesaw 200 do not have a seesaw motion due to the balance of the stress; since the blocking protrusion 220 has an inclined surface 221, when the button 300 is pressed down, the button 300 will push the sliding type rocker 200 to slide along the sliding guide slot 111 through the inclined surface 221, and the sliding type rocker 200 further drives the trigger rod 500 thereon to move, so that the trigger rod 500 can contact with the contact of the lifting driving part 50, and the contact is triggered by the trigger rod 500 to connect the circuit of the lifting driving part 50, so that the lifting driving part 50 can drive the fixed length cutting mechanism 60 to press down to cut the workpiece 70;

the pressing action of the two buttons 300 is cancelled, the sliding rocker 200 can reset under the acting force of the reset spring 400, then, the trigger rod 500 is separated from the contact of the lifting driving part 50, the piston of the lifting driving part 50 with the cylinder structure can reset under the acting force of the built-in spring, and the lifting driving part 50 drives the fixed length dividing mechanism 60 to ascend and keep away from the workpiece 70;

if the two buttons 300 are not pressed simultaneously, the two ends of the sliding type rocker 200 are forced to move in a seesaw manner due to unbalanced force (as shown in fig. 11), when the sliding type rocker 200 moves in a seesaw manner, one of the blocking protrusions 220 of the sliding type rocker 200 is sunk into the corresponding blocking groove 112, the blocking groove 112 blocks the entire sliding type rocker 200 by the blocking protrusion 220, the sliding of the sliding type rocker 200 is prevented, and the trigger lever 500 cannot contact with the contact point of the elevation driving part 50;

therefore, the design can improve the production safety, the two hands of the operator need to press the two buttons 300 respectively and simultaneously to start the lifting driving part 50, and at this time, the two hands of the operator completely leave the workpiece 70, so that the two hands of the operator are prevented from being cut by the left cutting knife 62 and the right cutting knife 63, and the production safety is greatly improved.

Here, in the present invention, the extension rod 310 is inserted into the cavity wall of the accommodating cavity 110 and is pressed against the inclined surface 221 of the blocking protrusion 220 by the extension spring 320, and the extension spring 320 has two functions: on one hand, the extension spring 320 provides an elastic restoring force to the extension bar 310, and on the other hand, the extension spring 320 applies an indirect elastic force to the inclined surface 221 of the blocking protrusion 220 through the extension bar 310, thereby balancing the sliding rocker 200 without an external force.

In order to further improve the production safety, the safety driving device 80 of the present invention further includes a false touch prevention knob 600 (as shown in fig. 8 and 9), the false touch prevention knob 600 is rotatably disposed on the fixing base 100, the false touch prevention knob 600 is a cavity structure with hollow two ends, and the button 300 is sleeved in the hollow cavity of the false touch prevention knob 600.

As shown in fig. 9, in addition, a blocking ring 610 is disposed in the hollow cavity of the anti-accidental-touch knob 600, a blocking rod 330 is disposed on the outer side wall of the button 300, and an unlocking through hole 611 for avoiding the blocking rod 330 is disposed on the blocking ring 610. In fig. 9, the erroneous touch prevention knob 600 is shown in a broken-away state in order to clearly show the internal structure of the erroneous touch prevention knob 600.

Through setting up mistake proofing and touching knob 600, can follow two aspects and protect button 300 simultaneously, prevent that button 300 from being touched by the mistake and bumping:

on the first hand, the false touch prevention knob 600 is a cavity structure with two hollow ends, and the button 300 is sleeved in the hollow cavity of the false touch prevention knob 600, so that the button 300 is completely wrapped in the hollow cavity of the false touch prevention knob 600, an operator can only press the button 300 at one opening end of the false touch prevention knob 600 through fingers, and if the operation is not performed, the pressing operation of the button 300 cannot be realized;

on the other hand, the anti-accidental-touch knob 600 can rotate, when the unlocking through hole 611 on the blocking ring 610 does not correspond to the blocking rod 330, the blocking rod 330 is blocked by the blocking ring 610, so that the button 300 cannot be pressed down; only by rotating the anti-mistouch knob 600, the unlocking through hole 611 of the blocking ring 610 corresponds to the blocking rod 330, and at this time, the blocking rod 330 smoothly passes through the unlocking through hole 611, so that the button 300 is pressed down.

To further enhance the safety of production, the safety drive 80 of the present invention further includes a mortise lock mechanism 700 (shown in FIG. 6). It should be noted that the mortise lock mechanism 700 is not used in a normal condition, and is only considered to be used in a special condition, for example, when an operator leaves a station for a long time, the operator is prevented from operating the equipment by a foreign person.

As shown in fig. 7, in particular, the mortise lock mechanism 700 includes: a mortice lock knob 710, a mortice lock dial 720, and a mortice lock lever 730.

The fixing base 100 is provided with a hidden slot 120 (as shown in fig. 7), the center of the hidden lock rotary plate 720 is arranged in the hidden slot 120, and the middle of the hidden lock lever 730 is arranged in the hidden slot 120.

The mortice lock knob 710 is located outside the concealed slot 120 and is connected to the mortice lock dial 720.

The edge of the built-in lock turntable 720 is provided with an unlocking notch 721 (as shown in fig. 7), and the outer side wall of the anti-false-touch knob 600 is provided with a locking tooth groove 620 (as shown in fig. 7).

As shown in fig. 12, one end of the built-in lock lever 730 is pressed against the edge of the built-in lock dial 720, and the other end is pressed against the locking spline 620 of the anti-accidental touch knob 600; alternatively, as shown in fig. 13, one end of the built-in lock lever 730 is received in the unlocking notch 721 of the built-in lock dial 720, and the other end is separated from the locking spline 620 of the anti-mistouching knob 600.

The method of use and the principle of operation of the above-described mortise lock mechanism 700 will now be described:

referring to fig. 12, when the operator leaves the operation station for a long time, the mortise lock mechanism 700 needs to be unlocked, the unlocking method is as follows: the built-in lock knob 710 is rotated, the built-in lock knob 710 further drives the built-in lock turntable 720 to rotate, so that one end of the built-in lock lever 730 is pressed on the edge of the built-in lock turntable 720, then the other end of the built-in lock lever 730 falls into the upper locking tooth groove 620 of the anti-accidental touch knob 600, the upper locking tooth groove 620 is clamped by the built-in lock lever 730, therefore, the anti-accidental touch knob 600 cannot be rotated freely, and the blocking rod 330 on the button 300 is blocked by the blocking ring 610 at the moment, so that the button 300 can be fully ensured not to be pressed freely, and the use safety is improved;

referring also to FIG. 13, when the operator returns to the operating position, the mortise lock mechanism 700 needs to be closed as follows: when the hidden lock knob 710 is rotated in the opposite direction, the hidden lock knob 710 further drives the hidden lock rotary table 720 to rotate in the opposite direction, when the unlocking gap 721 of the hidden lock rotary table 720 reaches a designated position, the unlocking gap 721 corresponds to one end of the hidden lock lever 730, at this time, the mistaken touch prevention knob 600 can be rotated, a rotating force is slightly applied to the mistaken touch prevention knob 600, one end of the hidden lock lever 730 can be popped out from the locking tooth groove 620, the other end of the hidden lock lever 730 can be sunk into the unlocking gap 721, and the unlocking gap 721 provides an avoiding space for the rotation of the hidden lock lever 730.

It should be noted that, in the present invention, only one of the anti-false-touch knobs 600 needs to be controlled by one set of the built-in lock mechanism 700 (as shown in fig. 7), and two anti-false-touch knobs 600 do not need to be controlled simultaneously, thereby simplifying the setting of the mechanism. The explanation is as follows: when one of the anti-false-touch knobs 600 is controlled using one set of the built-in lock mechanism 700, even if the button 300 of the other anti-false-touch knob 600 is pressed, one of the blocking protrusions 220 of the sliding type rocker 200 is sunk into the corresponding blocking groove 112 due to the "seesaw" movement of the sliding type rocker 200, thereby preventing the sliding type rocker 200 from sliding.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
