Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

A drive connection mechanism, comprising: a first joining member 10 joining the workpiece 100; a second connecting member 20 connected to the driving member 1; wherein, the driving member 1 is slidably disposed on the mounting frame 30; when the workpiece 100 is close to the driving member 1, the first connecting member 10 is driven to be close to the second connecting member 20, and the first connecting member 10 and the second connecting member 20 are mutually matched, so that the driving member 1 slides along the mounting frame 30 to facilitate the driving member 1 to be connected with the workpiece 100.

The workpiece 100 is detachable relative to the driver 1; the mounting frame 30 is relatively fixed in position, and the driver 1 is arranged on the mounting frame 30. After the workpiece 100 is unloaded, the first connecting part 10 is separated from the second connecting part 20, the second connecting part 20 loses the supporting force of the first connecting part 10, and the driving part 1 moves relative to the mounting part 30 to find the balance position due to the self gravity; when the workpiece 100 is reconnected to the driving member 1, the first connecting member 10 gradually approaches the second connecting member 20 and finally contacts the second connecting member 20, thereby providing a supporting force to the second connecting member 20, so that the driving member 1 moves along the mounting frame 30 to be in balance again; as will be readily understood, the position of the first connecting member 10 will vary with the type of the workpiece 100, and thus, after the first connecting member 10 contacts the second connecting member 20, the position of the second connecting member 20 will be adjusted accordingly, so as to guide the driving member 1 to vary in position and adapt to the workpiece 100; in this case, the workpiece 100 enters the mounting frame 30, and the driving member 1 is adjusted to correspond to the workpiece 100 to facilitate the connection therebetween.

Conceivably, the position where the workpiece 100 is connected to the driving member 1 is referred to as a connection end; the position of the first connecting member 10 relative to the connecting end is fixed, that is, the position of the first connecting member 10 relative to the connecting end is always unchanged when the model or state of the workpiece 100 is adjusted. In this way, the adjusted workpiece 100 enters the mounting frame 30 again, because the matching manner of the first connecting piece 10 and the second connecting piece 20 is not changed; meanwhile, after the position of the second connecting piece 20 is adjusted by the first connecting piece 10, the matching position of the first connecting piece 10 and the second connecting piece 20 is also fixed; finally, the driving member 1 driven by the second connecting member 20 can be accurately opposite to the connecting end of the workpiece 100, so that connection can be realized.

In short, the workpiece 100 may require debugging, maintenance, replacement, or deformation during use; at this time, the position of the connection end of the workpiece 100 may be changed. However, the position of the first connecting element 10 relative to the connecting end is always unchanged, and at the same time, the relative position of the second connecting element 20 and the drive element 1 is also always unchanged; in this way, the first connecting part 10 cooperates in the same way with the second connecting part 20, which ensures a correct connection of the driver 1 and the connecting end.

For example, in one embodiment, the mounting frame 30 is provided with a guide 3 extending in a vertical direction, and the driving member 1 is slidably connected with the guide 3 and can move along the guide 3; the lower end of the guide piece 3 is provided with a stop piece 4; the stop 4 is able to hold the drive element 1, preventing the drive element 1 from sliding out of the guide 3.

In this embodiment, when the second connecting member 20 is separated from the first connecting member 10 and is not supported by external force, the driving member 1 will move downward along the guiding member 3 due to its own weight and finally abut against the stop member 4; the stop 4 holds the driver 1 so that the driver 1 is in equilibrium. Similarly, after the first connecting piece 10 contacts the second connecting piece 20 and applies a supporting force to the second connecting piece 20, the second connecting piece 20 is lifted, so that the driving piece 1 is forced to move upwards along the guide piece 3; when the first connecting member 10 and the second connecting member 20 are matched in place, the driving member 1 does not move in the guide member 3, and the connecting end of the driving member 1 faces the connecting end of the workpiece 100.

Wherein, the guide 3 can adopt guide components such as guide rods, guide rails and the like; the stopper 4 may be a stopper, a lever, or the like. Further, in order to prevent the driving member 1 from sliding down and striking the stopper 4, a buffer member (not shown) may be provided near the stopper 4; the buffer piece can adopt a hydraulic buffer; when driving piece 1 glides along guide 3, at first contact bolster, through the bolster, can slow down the speed that driving piece 1 glided, and then make driving piece 1 gently contact stop part 4, guarantee safe in utilization, improve life.

In order to ensure that the relative position of the driving member 1 and the workpiece 100 is stable when the driving member 1 is connected to the workpiece, the driving connection mechanism further comprises a control member 5, and the control member 5 is connected to the driving member 1 and applies force to the driving member 1 so as to keep the position of the driving member 1 stable.

In one embodiment, the control member 5 may be an elastic member; the elastic element is arranged between the driving element 1 and the mounting frame 30; after the second connecting member 20 loses the support of external force, the driving member 1 moves relative to the mounting frame 30, so that when finding a balance position, the elastic member is compressed or stretched, and the elastic force generated can be abutted against the self weight of the driving member 1, so that the driving member 1 is in a stable state; after the first connecting piece 10 contacts the second connecting piece 20 and exerts a supporting force on the second connecting piece 20, the elastic piece deforms reversely to adapt to the position change of the second connecting piece 20, and at the moment, the elastic force of the elastic piece pulls the second connecting piece 20 to press the first connecting piece 10, so that the relative positions of the driving piece 1 and the workpiece 100 are accurate and stable.

Specifically, the elastic member may employ a spring. In one embodiment, referring to fig. 1, when the driving member 1 is adjusted in position in the vertical direction, one end of the spring abuts against the lower end of the driving member 1, and the other end abuts against the stop member 4; since the guide member 3 is disposed at the mounting bracket 30 and the stopper member 4 is disposed at the lower end of the guide member 3, it can be seen that the stopper member 4 is fixedly disposed with respect to the mounting bracket 30; at this time, the spring is sandwiched between the driver 1 and the stopper 4 in the vertical direction; thus, after the external supporting force is lost, the driving piece 1 slides downwards along the guide piece 3 to compress the spring, and the elastic force obtained by the compression of the spring supports the driving piece 1; after the external force is obtained for supporting, the driving member 1 is lifted by the external force, the spring is stretched to generate a pulling force, and the pulling force is matched with the gravity of the driving member 1, so that the driving member 1 has a downward movement trend, and the first connecting member 10 is enabled to compress the second connecting member 20 all the time. In another embodiment, one end of the spring abuts against the upper end of the driver 1, and the other end abuts against a portion (not shown) of the mounting frame 30 protruding towards the driver 1; at this time, the spring is sandwiched between the driver 1 and the mounting bracket 30 in the vertical direction; thus, after the external force is supported, the driving member 1 is lifted by the external force, the spring is compressed, and the elastic force generated by the compression presses down the driving member 1, so that the first connecting member 10 compresses the second connecting member 20 all the time.

In yet another embodiment, the control member 5 may employ a cylinder; the output end of the air cylinder is connected with a driving piece 1; the cylinder outputs a certain force, after the second connecting piece 20 loses the support of external force, the driving piece 1 moves relative to the mounting frame 30, so that when the balance position is found, the force output by the cylinder just matches with the driving piece 1 and the mounting frame 30, and the driving piece 1 is in a stable position; after the first connecting piece 10 contacts the second connecting piece 20 and exerts a supporting force on the second connecting piece 20, the output end of the air cylinder is compressed, and the force of the air cylinder is exerted on the first connecting piece 10 through the driving piece 1 and the second connecting piece 20, so that the accurate and stable relative positions of the driving piece 1 and the workpiece 100 are ensured.

Specifically, referring to fig. 2, the cylinder may be disposed above the driving member 1 to apply force to the driving member 1 from top to bottom; after the external supporting force is lost, the pulling force output by the cylinder can offset the gravity of the driving piece 1, so that the driving piece 1 is prevented from rapidly sliding down along the guide piece 3 and impacting the stop piece 4; of course, when the pulling force output by the cylinder is large enough, the stop piece 4 can be omitted, and the gravity of the driving piece is offset by the pulling force, so that the balance can be realized; after the external force is obtained for supporting, the driving piece 1 is lifted by the external force and moves upwards along the guide piece 3, so that the output end of the air cylinder is compressed, the air cylinder outputs pressure to push the driving piece 1 downwards, and the first connecting piece 10 is enabled to compress the second connecting piece 20 all the time.

For the first connecting piece 10 and the second connecting piece 20, the two pieces can be contacted with each other and mutually influenced to realize 'fit'; for example, the first and second connection members 10 and 20 may be formed of a plate having a certain length. Specifically, the driving member 1 is slidably disposed on the mounting frame 30, and a plate is disposed near an output end of the driving member, and extends toward the direction of the butted workpiece 100; another plate is arranged near the connecting end of the workpiece 100 connected with the driving element 1, and when the workpiece 100 is over against the driving element 1, the plate on the workpiece 100 is over against the plate on the driving element 1; along with work piece 100 is constantly close to driving piece 1, two plates are constantly close, and the plate on the work piece 100 can the plate on the contact driving piece 1, and then the position of adjustment driving piece 1 for the output of driving piece 1 can be even the link of work piece 100 all the time.

It should be added that, according to the variation of the connecting end of the workpiece 100, the driving member 1 may move in the vertical direction with respect to the mounting frame 30, or may move in the horizontal direction with respect to the mounting frame 30; correspondingly, when moving along the vertical direction, the first connecting piece 10 can lift the second connecting piece 20 upwards or press the second connecting piece 20 downwards; when moving along the horizontal direction, the first connecting piece 10 can correspondingly push or pull the second connecting piece 20; the application is not limited as long as the force on the driving member 1 can be balanced.

Further, when the first connecting piece 10 and the second connecting piece 20 are plates with a certain length, a slope may be arranged at the end of the second connecting piece 20 close to the first connecting piece 10; for example: when the second connecting piece 20 is lifted up from the first connecting piece 10, the second connecting piece 20 abuts against the lower surface of the first connecting piece 10, and at least at the position close to the first connecting piece 10, the lower surface inclines towards the first connecting piece 10; referring to fig. 1 in particular, that is, the thickness of the end portion of the second connecting element 20 close to the first connecting element 10 is gradually reduced, so that the first connecting element 10 is located below the end portion of the second connecting element 20 when approaching to the second connecting element 20, and thus the second connecting element 20 is lifted, and it is avoided that the first connecting element 10 cannot enter below the second connecting element 20 and lift the second connecting element 20 due to the over-high initial position of the first connecting element 10. Alternatively, the first connecting member 10 will support the upper surface of the second connecting member 20, and at least at the position close to the second connecting member 20, the upper surface is inclined downwards towards the second connecting member 20, so that when the first connecting member 10 approaches the second connecting member 20, the end part is under the second connecting member 20, and thus the second connecting member 20 is lifted. Still alternatively, the lower surface of the second link 20 is inclined upward toward the first link 10, and the upper surface of the first link 10 is inclined downward toward the second link 20, so that the first link 10 approaches to lift up the second link 20.

In order to facilitate the connection of the workpiece 100 to the driving member 1 after the first connecting member 10 contacts the second connecting member 20 and can continue to move forward along the second connecting member 20, in another embodiment, a follower is used for one of the first connecting member 10 and the second connecting member 20; the other of the first and second connectors 10 and 20 employs a top block.

For example, referring to fig. 2, the first connecting member 10 employs a follower, and the second connecting member 20 employs a top block; when the workpiece 100 is close to the driving element 1, the first connecting element 10 is gradually close to the second connecting element 20, and the follower jacks up the jack block from the lower part and drives the driving element 1 to ascend, so that the position of the driving element 1 is adjusted corresponding to the connecting end of the workpiece 100, and the connecting is realized when the driving element 1 is just opposite to the connecting end of the workpiece 100. In addition, the first connecting piece 10 can adopt a top block, and the second connecting piece 20 adopts a follower; at this moment, the ejector pad is gradually close to the follower, and the ejector pad jacks up the follower from below, so as to drive the driving member 1 to ascend, so that the driving member 1 corresponds to the connecting end adjusting position of the workpiece 100, and the workpiece 100 is just connected to the driving member 1. The follower can roll on the surface of the ejector block, so that the first connecting piece 10 and the second connecting piece 20 can move relatively conveniently to the output end of the driving piece 1 to be connected with the connecting end of the workpiece 100, and the mutual friction between the first connecting piece and the second connecting piece and the damage to the contact surface of the first connecting piece and the second connecting piece to influence the final matching precision are avoided.

Further, as in the above embodiment, the connecting member of the top block is used, and at least the surface of the connecting member near the end of the follower is inclined toward the position where the follower is located, so as to guide the follower into the top block and avoid the positions from interfering with each other. For example, referring to fig. 2, the first connecting member 10 employs a follower, and the second connecting member 20 employs a top block; at this moment, the tip of kicking block lower surface is upwards inclined towards the follower for the kicking block main part is higher than under the condition of follower, and the tip of lower surface is less than the follower, so that the follower gets into the kicking block below, and lifts the kicking block, lifts driving piece 1 on finally realizing.

Further, in order to better achieve the mutual fit of the first connecting member 10 and the second connecting member 20, the top block is recessed against the end face portion of the follower to form a receiving pit 21; when the first connector 10 and the second connector 20 are engaged with each other, the follower can enter the receiving pit 21, thereby defining the position of the follower.

It is easy to understand that, when the workpiece 100 is connected to the driving member 1, the connection position of the first connecting member 10 and the second connecting member 20 is fixed; after the workpiece 100 is debugged, replaced or maintained each time, although the configuration of the workpiece 100 is changed, the relative positions of the connecting end of the workpiece 100 and the first connecting piece 10 are always unchanged, and the position of the driving piece 1 can be adjusted by matching the first connecting piece 10 and the second connecting piece 20 in a unified state. Specifically, the fitting state of the second link 20 and the first link 10 is fixed each time the driver 1 connects the workpiece 100; for example, when the follower enters the receiving pit 21, the drive 1 is just connected to the workpiece 100. Specifically, when the first connecting piece 10 and the second connecting piece 20 respectively adopt a top block and a follower, and the driving piece 1 is connected with the workpiece 100, the follower is just positioned in the accommodating pit 21; the two sides of the accommodating pit 21 are provided with slopes, so that the follower can be prevented from rolling freely and leaving a fixed position, and the connection stability of the driving piece 1 and the workpiece 100 is further ensured.

Further, in order to facilitate the connection of the workpiece 100 and the driving member 1, the output end of the driving member 1 is provided with a driving coupling 6, and the connection end of the workpiece 100 close to the driving member 1 is provided with a driven coupling 7; the driving coupling 6 can be connected with the driven coupling 7, and then the driving part 1 and the upper cutter shaft 111 are connected in a transmission way. The coupling is provided to facilitate the connection of the workpiece 100 to the driving member 1, as will be described in detail below.

The application also discloses a splitting machine, which comprises the driving connecting mechanism; meanwhile, in the slitting machine, the workpiece 100 described above is a knife module, and the knife module includes: the upper cutter assembly 110, the upper cutter assembly 110 includes an upper cutter shaft 111, a plurality of groups of upper cutters 112 arranged on the upper cutter shaft 111 at intervals; the lower knife assembly 120, the lower knife assembly 120 includes a lower knife shaft 121 and a plurality of groups of lower knives 122 arranged on the lower knife shaft 121 at intervals; the tool rest 130, the upper tool assembly 110 and the lower tool assembly 120 are oppositely arranged on the tool rest 130 along the vertical direction; wherein, the upper cutters 112 correspond to the lower cutters 122 one to one; the first connecting piece 10 is arranged on the tool holder 130.

When the splitting machine works, a base material to be split penetrates through the space between the upper cutter assembly 110 and the lower cutter assembly 120, the driving piece 1 drives the upper cutter shaft 111 and the lower cutter shaft 121 to synchronously rotate, so that the linear speeds of the upper cutter 112 and the lower cutter 122 in each group (one upper cutter 112 and one lower cutter 122 which are correspondingly arranged are regarded as one group) are the same, and efficient splitting is realized.

In one embodiment, the opposite ends of the upper knife shaft 111 and the lower knife shaft 121 may be linked by a timing belt assembly (not shown); at this time, the driving member 1 connects the other end of the upper cutter shaft 111 or the lower cutter shaft 121. So, 1 actions of driving piece, the drive is rotatory rather than the arbor that links to each other, through the transmission of hold-in range subassembly, can drive another arbor synchronous revolution, and then realizes cutting to the substrate.

In another embodiment, the splitting machine further includes a second driving member 2 connected to the lower knife shaft 121 to drive the lower knife shaft 121 to rotate. At this time, the driver 1 can connect the upper cutter shaft 111 and further drive the upper cutter shaft 111 to rotate. That is, the upper cutter shaft 111 and the lower cutter shaft 121 are driven by different drivers and can rotate independently. Wherein, the driving member 1 and the second driving member 2 can both adopt servo motors.

As can be easily understood, the upper cutter shaft 111 and the lower cutter shaft 121 continuously cut the substrate and wear the edge end; after a period of use, the blade needs to be sharpened to ensure cutting accuracy. In practical application, the upper cutter and the lower cutter may have two configuration situations; in one case, the upper cutter and the lower cutter are both circular cutters which are both sharp cutters, and the cutting edges are protruded and easy to wear; in another case, one of the upper and lower cutters adopts a sharp cutter, the other adopts a flat cutter, and the cutting edge of the flat cutter is retracted and does not protrude outside, so that the flat cutter is not easy to wear, therefore, only the sharp cutter needs to be sharpened during cutter repair, but the flat cutter does not need to be sharpened.

For this purpose, when the upper and lower cutters are circular cutters (not shown), the driving member 1 is slidably disposed on the mounting frame 30, and the second driving member 2 is also slidably disposed on the mounting frame 30; meanwhile, the relative arrangement direction of the driving member 1 and the second driving member 2 is the same as the relative arrangement direction of the upper cutter shaft 111 and the lower cutter shaft 121. For example, the upper cutter shaft 111 and the lower cutter shaft 121 are disposed opposite to each other in the vertical direction, and the drive member 1 and the second drive member 2 are also disposed opposite to each other in the vertical direction. In addition, a second connecting member 20 is connected to each of the driving member 1 and the second driving member 2, and a first connecting member 10 is connected to each of the upper cutter shaft 111 and the lower cutter shaft 121. During trimming, both the upper blade 112 and the lower blade 122 are trimmed, and therefore, after the upper and lower blades are reassembled, the positions of the upper blade assembly 110 and the lower blade assembly 120 are changed. For example, the upper knife shaft 111 and the lower knife shaft 121 are arranged oppositely in the vertical direction, after knife trimming, since the diameter of the knife is reduced, in order to ensure that the base material can pass through at the same position after the knife module is installed in the slitting machine, the lower knife shaft 121 needs to be moved upwards, and the upper knife shaft 111 needs to be moved downwards, so as to ensure that the cutting position of the knife module remains unchanged after the knife module is connected with the driving member. But the relative position of the first connecting member 10 and its corresponding arbor is unchanged. Thus, when the knife die assembly is installed in the splitting machine, the first connecting part 10 of the upper knife shaft 111 is gradually close to the second connecting part 20 for jacking the driving part 1, the first connecting part 10 of the lower knife shaft 121 is gradually close to the second connecting part 20 for jacking the second driving part 2, and the two groups of connecting driving mechanisms are independently matched to adjust the driving part 1 and the second driving part 2 to respectively correspond to the upper knife shaft 111 and the lower knife shaft 121.

When one of the upper and lower cutters is a sharp cutter and the other is a flat cutter, the driving member corresponding to the sharp cutter is slidably disposed on the mounting frame 30, and the other driving member corresponding to the flat cutter is fixedly disposed relative to the mounting frame 30. For example, referring to fig. 2, when the upper blade 112 is a sharp blade and the lower blade 122 is a flat blade; the upper cutter 112 requires a knife repair, while the lower cutter 122 does not; therefore, when the cutter repairing is finished and the cutter die assembly is arranged in the splitting machine, the position of the lower cutter shaft 121 can be unchanged, and the upper cutter shaft 111 needs to move downwards so as to ensure that the position of the base material passing through the cutter die assembly is unchanged and ensure the cutting stability and continuity; at this time, the driving member 1 is slidably disposed on the mounting frame 30 along the vertical direction, the driving member 1 is connected to the second connecting member 20, the upper knife shaft 111 is correspondingly connected to the first connecting member 10, and the driving member 1 is adjusted to the upper knife shaft 111 by the mutual matching of the first connecting member 10 and the second connecting member 20; and the lower arbor 121 can directly abut against the second driver 2.

It is easy to understand that when cutting, the cutting effect can be ensured only by ensuring the consistency of the rotating linear speeds of the upper cutter and the lower cutter. Therefore, when one of the upper cutter and the lower cutter adopts a sharp knife and the other adopts a flat knife, after the knife is repaired, the angular speed of the sharp knife can be changed, if the synchronous belt component is adopted to link the two groups of cutters, the tooth width of the synchronous belt wheel needs to be synchronously adjusted, therefore, the two groups of driving components are adopted to respectively drive one group of cutter components, and the operation is more convenient.

Furthermore, in order to facilitate the connection between the cutter shaft and the driving part, the output end of the driving part 1 is provided with a driving coupling 6, and one end of the upper cutter shaft 111 close to the driving part 1 is provided with a driven coupling 7; the driving coupling 6 can be connected with the driven coupling 7, and then the driving part 1 and the upper cutter shaft 111 are connected in a transmission way.

Through setting up driving coupling 6 and driven coupling 7, can realize going up the connection and the separation of arbor 111 and driving piece 1 conveniently. When the first connecting piece 10 lifts the second connecting piece 20 to the state that the second connecting piece 20 is stable, the output end of the driving piece 1 is over against the connecting end of the upper cutter shaft 111, and at the moment, the driving coupler 6 can be in butt joint with the driven coupler 7 along with the fact that the cutter die assembly further approaches the driving piece 1; after the driving coupling 6 is connected with the driven coupling 7, the power of the driving part 1 can be transmitted to drive the upper cutter shaft 111 to rotate.

Similarly, when the lower cutter shaft 121 is independently connected with the second driving member 2, the output end of the second driving member 2 can also be provided with the driving coupling 6, and the connecting end of the lower cutter shaft 121 is provided with the matched driven coupling 7, so as to link the two.

For making things convenient for the cutting die subassembly cutting machine of packing into, mounting bracket 30 includes: the large plate 31 is provided with the driving piece 1 in a sliding way; the cutting die mounting plate 32, the cutting die mounting plate 32 is connected with the large plate 31; wherein the cutting die assembly can enter the cutting die mounting plate 32 and then approach or leave the large plate 31 along the cutting die mounting plate 32, so that the cutting die assembly is convenient to approach or leave the driving member 1.

As will be readily appreciated, the die mounting plate 32 serves to support the die assembly; no matter how the upper and lower cutters are sharpened, the configuration of the cutter holder 130 is unchanged, that is, the overall configuration of the cutter die assembly is not changed, and the position of the cutter die assembly is not changed after the cutter die assembly enters the slitting machine; the change of the trimming knife is the relative position of the upper cutting knife and the lower cutting knife. For example, referring to fig. 2, when the upper and lower cutters are disposed opposite to each other in the vertical direction, the upper and lower cutters may be adjusted in position in the vertical direction without being shifted in the horizontal direction (front, rear, left, and right) after the trimming operation is completed and the cutter block assembly is assembled into the slitting machine. Therefore, the cutting die mounting plate 32 is arranged, the direction of the cutting die assembly which is not changed can be limited, and the cutting die assembly can accurately move to the large plate 31 and is close to the driving piece conveniently.

Further, the slitting machine also includes a positioning assembly 40 for defining the position of the knife block assembly on the knife block mounting plate 32.

Specifically, the positioning assembly 40 may be disposed on the cutting die mounting plate 32, or may be disposed on the large plate 31, and since the position of the mounting frame 30 is relatively fixed, the positioning assembly 40 disposed thereon can function to define the position of the cutting die assembly. Wherein the positioning assembly 40 is a clamp capable of clamping the tool holder 130, thereby defining the position of the die assembly. Alternatively, the positioning assembly 40 may employ a suction cup capable of sucking the tool holder 130, thereby defining the position of the die assembly.

Referring to fig. 2 and 3, in one embodiment, the positioning assembly 40 includes a positioning member 41 and a positioning driving member 42, and the positioning driving member 42 is connected to the positioning member 41 and can drive the positioning member 41 to move toward the tool post 130, so that the positioning member 41 can be inserted into the tool post 130 to define the position of the tool post 130. Specifically, the positioning assemblies 40 are arranged on two sides of the cutting die mounting plate 32, and the cutting die assemblies are in place after approaching the large plate 31 along the cutting die mounting plate 32 until the cutter shaft is connected with the driving part; the positioning driving member 42 then drives the positioning member 41 to extend toward the cutting die assembly, so that the positioning member 41 is inserted into the positioning hole of the tool holder 130, thereby controlling the tool holder 130.

The positioning hole may be directly formed at a position corresponding to the tool holder 130, or may be formed in another member provided at a position corresponding to the tool holder 130. The positioning member 41 may be an insertion rod, an insertion block, or the like; the positioning driving member 42 may be a pneumatic cylinder, an electric cylinder, or the like.

Further, the positioning assembly 40 further includes guide blocks 43 oppositely disposed at both sides of the knife module mounting plate 32; the two guide blocks 43 are arranged at intervals, and a channel for the knife die assembly to enter is reserved, so that the knife die assembly can be guided to be close to or far away from the large plate 43 along the guide blocks 43.

Further, to facilitate movement of the die assembly on the die mounting plate 32, rollers 44 may be provided below the carriage 130 to facilitate rolling of the die assembly into and out of the die mounting plate 32. In order to limit the position of the roller 44, a recess 45 can be further arranged on the corresponding cutting die mounting plate 32 after the cutting die assembly is in place, so that the roller 44 of the cutting die assembly in place is sunk into the recess 45 and is not easy to displace.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. Such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
