Description

Technical Field

[0001] The invention relates to the technical field of cardboard processing, in particular to a cardboard cutting and stacking production line for paper box processing. Background Art

[0002] A paper box is a three-dimensional shape, which is composed of a polyhedron formed by the movement, stacking, folding and surrounding of several surfaces.

[0003] The cutting process of cardboard is one of the main processes of carton processing. The cutting process is to cut the cardboard along the edge of the printed pattern on it to form a foldable cardboard structure. Since the cutting process will produce waste, the cutting process is often accompanied by the separation of waste from the cut cardboard and the stacking of the cut cardboard. As recorded in the text of a cutting device for environmentally friendly carton production and processing with Chinese patent publication number CN115519825A, a suction component is set to suck the fine debris generated during cutting into the box through the discharge port; thereafter, at the end of cutting, the staff pushes the waste to the discharge ports on both sides of the upper surface of the box, and starts the crushing component to crush and collect the waste at the discharge port. Thereafter, as recorded in the text of a cardboard cutting device with Chinese patent publication number CN117549373A and the text of a cardboard printing and cutting device for carton production with Chinese patent publication number CN118650926A, it is transported to the packing table through a conventional conveyor belt.

[0004] In the actual cardboard cutting process, cardboard is often cut synchronously with multiple layers stacked on top of each other. However, in order to ensure the quality of cutting, although the number of stacked layers will not be too many, it will still result in a lot of waste and cut cardboard after cutting. If the cut cardboard is manually sorted according to the cited patent, there will be problems of low automation and low production efficiency. In addition, since multiple layers of cardboard are not cut synchronously and sorted and transported to the packaging table, it is often necessary to manually stack the cut cardboard to achieve synchronous packaging of most of the cut cardboards, and there is also a lack of automation. In summary, how to form an efficient and highly automated cardboard cutting and stacking production line is a technical problem that needs to be solved urgently. Summary of the invention

[0005] In order to avoid and overcome the technical problems existing in the prior art, the present invention provides a cardboard cutting and stacking production line for paper box processing, which can efficiently and automatically separate waste from the cut cardboard and realize automatic stacking of the cut cardboard.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A cardboard cutting and stacking production line for paper box processing comprises a cutting mechanism, wherein a shaping cutter driven by a cutting power assembly and performing a lifting action is arranged directly above a cutting table of the cutting mechanism, the shaping cutter is a closed frame structure penetrating from top to bottom, and the inner peripheral contour of the shaping cutter matches the outer peripheral contour of the cut cardboard; a lifting mechanism is also arranged on the cutting table, wherein a lifting part is located directly below the cut cardboard, the lifting part can slide through the table surface of the cutting table, and when the lifting part performs an ascending action, the cut cardboard is pushed upward along the inner cavity wall of the shaping cutter; a feeding mechanism is arranged at the feeding end of the cutting table, and the feeding mechanism continuously supplies cardboard to the cutting table, and the supplied cardboard pushes the waste material remaining on the cutting table away from the cutting area of ​​the cutting table;

[0008] The utility model also includes a transfer and stacking device for transferring the cut cardboards ejected by the lifting part and stacking the cut cardboards.

[0011] As a further solution of the present invention: the transfer and stacking device also includes a transfer mechanism, which transfers the cut cardboard ejected by the ejection mechanism, and the transfer mechanism includes a transfer seat driven by a transfer transmission assembly and performing horizontal linear reciprocating motion, and a supporting member is fixed on the transfer seat. When the lifting part ejects the cut cardboard, the upper part of the lifting part protrudes above the shaping cutter, and the movement path of the supporting member and the upper part of the lifting part are misaligned with each other and intersect with the bottom of the ejected cut cardboard.

[0012] As a further solution of the present invention: a transfer pressing plate for pressing the cut cardboard is arranged directly above the supporting member, and the transfer pressing plate is driven by a transfer pressing power assembly on the transfer seat to perform lifting action.

[0013] As a further solution of the present invention: the supporting member is a supporting rod arranged in a length direction parallel to the horizontal linear reciprocating motion direction of the transfer seat, and the supporting rods are arranged to be at least two parallel and spaced apart.

[0014] As a further solution of the present invention: it also includes a transfer mechanism for receiving the cut cardboard, the transfer mechanism includes a transfer table, the transfer table is composed of at least three strip surfaces arranged in parallel and spaced apart, the horizontal linear reciprocating motion direction of the transfer seat is parallel to the length direction of the strip surfaces, and at least two supporting rods are respectively inserted into the intervals between adjacent strip surfaces; the transfer mechanism also includes a unloading lifting transmission assembly that can drive the transfer seat to perform lifting and lowering movements, when the unloading lifting transmission assembly drives the transfer seat to perform a descending movement, the supporting rods slide to the intervals between the strip surfaces, and place the cut cardboard on the supporting rods on the strip surfaces.

[0017] As a further solution of the present invention: a vertically arranged baffle bar is arranged at the conveying end of the belt conveyor assembly, a horizontal support bar is fixed to the side of the baffle bar close to the belt conveyor assembly, the cantilever end of the horizontal support bar is arranged adjacent to the conveying end of the belt conveyor assembly, and the upper surface of the horizontal support bar is lower than the upper surface of the belt of the belt conveyor assembly.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Cutting cardboard with a shaping cutter whose inner periphery is matched with the outer periphery of the cut cardboard, so that when the shaping cutter cuts the cardboard, the formed cardboard can be cut at one time. And the lifting part of the ejecting mechanism is used to eject the cut cardboard upward along the inner cavity wall of the shaping cutter, thereby realizing the automatic dislocation separation between the cut cardboard and the waste.

[0020] After that, the supporting telescopic part is moved to the right below the cut cardboard by the stacking horizontal power assembly, and then the stacking lifting power assembly drives the supporting telescopic part to move upward to support the cut cardboard. After that, the stacking horizontal power assembly drives the supporting telescopic part and the cut cardboard to move to the designated area on the stacking platform, and the stacking lifting power assembly lifts the supporting telescopic part and the cut cardboard to the designated stacking height. At this time, the telescopic power assembly drives the supporting telescopic part to retract into the stacking seat, so that the cut cardboard loses the support of the supporting telescopic part and falls to the designated position on the stacking platform, thereby realizing the automatic stacking of the cardboard.

[0021] By automatically separating the cut cardboard from the waste materials and stacking the cut cardboard using a stacking mechanism, manual operation is not required, thereby improving the automation level and production efficiency of the cutting and stacking operations.

[0022] 2. When it is necessary to cut the cardboard into other shapes, the cutting mechanism replaces the shape cutter with an inner circumference that matches the shape. At the same time, the push block under the ejection column in the ejection mechanism that interferes with the lifting path and the outer peripheral contour of the shape cutter is removed, and all the avoidance sockets under the ejection column in the lifting path located in the inner circumference area of ​​the shape cutter are installed with push blocks, so that the cut cardboards of different shapes can be cut and the bottom of the cut cardboards of different shapes can be stably supported and lifted, thereby improving the adaptability to the cutting operation of cardboards of different shapes.

[0023] 3. When installing a new push block on the ejection mechanism, move the push block through the disassembly and assembly gap to just above the jacking plate until it is aligned with the corresponding avoidance socket. At this time, loosen the push block so that the small diameter end of the push block is inserted into the avoidance socket to complete the installation of the push block. In any case, when removing the push block, just slide the small diameter section of the push block upward out of the avoidance socket and take it out through the disassembly and assembly gap. The disassembly and assembly method of this push block is efficient and convenient, which effectively improves the efficiency of disassembly and assembly of the push block.

[0024] 4. Use the ejector pressing plate to press the top of the cut cardboard before the lifting part of the ejector mechanism ejects the cut cardboard, and when the top is lifted and moved upward to eject the cut cardboard, the ejector pressing plate moves upward synchronously. When the cut cardboard is a multi-layer stacked structure, it effectively prevents the cut cardboard from spreading during the ejection process.

[0025] 5. The upper surface of the belt of the belt conveyor assembly is in the form of a strip surface. When the transfer mechanism places the cut cardboard on the starting end of the belt conveyor assembly, the belt conveyor assembly can be rotated at a certain angle to transport the cut cardboard to the end of the belt conveyor assembly. Multiple groups of materials can be accumulated on the transfer platform at one time and then stacked by the stacking mechanism to achieve one-time synchronous stacking of multiple groups of materials. In addition, the process of accumulating multiple groups of materials on the transfer platform reserves a longer operating time for the stacking mechanism, so that when the time required for cardboard cutting and transfer is less than the time required for the stacking mechanism, there is no need to wait for the stacking mechanism to complete the operation after cutting and transfer, which effectively improves the production efficiency and production continuity of cardboard processing.

[0026] 6. A vertically arranged baffle bar is arranged at the conveying end of the belt conveyor assembly to prevent the cut cardboard b from falling from the conveying end of the belt conveyor assembly. Since a gap between the baffle bar and the conveying end of the belt conveyor assembly is inevitable when the baffle bar is arranged vertically, the cut cardboard may fall through the gap. A horizontal support bar is fixed on the side of the baffle bar close to the belt conveyor assembly. The cantilever end of the horizontal support bar is arranged near the conveying end of the belt conveyor assembly. The end of the cut cardboard transported to the end of the belt conveyor assembly is carried by the horizontal support bar, which can ensure the stable placement of the cut cardboard on the belt conveyor assembly.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] For ease of understanding, the specific structure and working mode of the present invention are further described below in conjunction with the accompanying drawings:

[0042] The specific structure of the present invention refers to Figure 1-12 As shown, its main structure includes a feeding mechanism 10, a transfer mechanism 20, a cutting mechanism 30, a transfer mechanism 40 and a stacking mechanism 50, and each mechanism will be described in detail below.

[0043] 1. Feeding mechanism 10

[0044] like Figure 1 As shown, the feeding mechanism 10 is arranged at one end of the cutting mechanism 30, and is used to continuously feed the cutting mechanism 30. Specifically, as Figure 2 and Figure 3 As shown, the feeding mechanism 10 includes a feeding table 11, on which a power seat 17 driven by a linear feeding power assembly 12 and capable of reciprocating linear motion along the cardboard conveying direction is installed. Specifically, the linear feeding power assembly 12 can be a screw slider mechanism or a cylinder; a pusher swing rod 13 is hinged on the power seat 17 through a horizontal hinge shaft perpendicular to the cardboard conveying direction. Under normal conditions, the pusher swing rod 13 is arranged vertically, with the front side of the pusher swing rod 13 following the power seat 17 to perform a process action as the pusher side, and the rear side as the reverse push side. A stopper 16 is fixed on the power seat 17 to keep the pusher swing rod 13 in a vertical arrangement when the pusher swing rod 13 performs a process action. Specifically, when the pushing rocker arm 13 performs the forward motion to feed the material, the pushing side of the pushing rocker arm 13 pushes the cardboard in the placement area on the feeding table 11, and causes the pushing rocker arm 13 to generate a torsional clamping force with the stop block 16 to maintain the vertical arrangement of the pushing rocker arm 13; when the pushing rocker arm 13 moves to the rear of the placement area and performs the return motion, the new cardboard a on the placement area abuts against the reverse pushing side of the pushing rocker arm 13, and causes the pushing rocker arm 13 to generate an evasive rotation motion to avoid the new cardboard a.

[0045] When in use, at the beginning of the production line, the pusher swing rod 13 is first reset to the initial position for the process action. At this time, the cardboard can be positioned and placed in the placement area of ​​the feed table 11. During the operation of the production line, the linear feed power assembly 12 drives the power seat 17 and the pusher swing rod 13 to perform the process action, thereby pushing the cardboard to the cutting area of ​​the cutting mechanism 30 for cutting. No matter how many groups of printed patterns are set on the cardboard, when the last group of printed patterns on the cardboard is pushed to the front of the cutting area, the pusher swing rod 13 will move to the rear of the placement area. At this time, a new cardboard a can be positioned and placed in the placement area; after the last group of printed patterns is pushed to the cutting area, the pusher swing rod 13 performs a return action with the power seat 17, and the new cardboard a on the placement area abuts against the reverse push side of the pusher swing rod 13, and the pusher swing rod 13 generates an avoidance rotation action to avoid the new cardboard a, so that the pusher swing rod 13 can be reset to the initial position again after the new cardboard a is placed in the placement area. In the process of the pushing swing rod 13 following the power seat 17 in the forward movement, the feeding mechanism 10 places the new cardboard a in the placement area in advance, and the hinged design of the pushing swing rod 13 allows the pushing swing rod 13 to avoid the new cardboard a and reset when making a return movement. Compared with the traditional method of placing the new cardboard a after the pushing swing rod 13 has reset after making a return movement, the continuous cutting operation of the cardboard will not be interrupted, thereby ensuring the cardboard processing efficiency.

[0046] Furthermore, in order to ensure that the pusher swing rod 13 is quickly reset after the avoidance rotation action and maintain the stable vertical arrangement of the pusher swing rod 13, a torsion spring shaft is installed on the horizontal hinge shaft, and when the torsion spring shaft releases energy, it generates an elastic thrust to push the pusher swing rod 13 to abut against the anti-rotation block 16. Of course, in actual implementation, the pusher swing rod 13 can be in the form of a light upper end and a heavy lower end, and the pusher swing rod 13 can maintain a stable vertical arrangement by using its own gravity.

[0047] On the basis of the above, if Figure 2 and Figure 3As shown, a long hole 111 is provided on the surface of the feeding table 11, and the length direction of the hole 111 is parallel to the conveying direction of the cardboard; the linear feeding power assembly 12 and the power seat 17 are located below the feeding table 11, and the upper end of the pusher swing rod 13 vertically passes through the long hole 111 and protrudes above the feeding table 11 under normal conditions, and the upper end of the pusher swing rod 13 forms a pushing part for pushing the cardboard to slide. Although in actual implementation, the linear feeding power assembly 12 and the power seat 17 can be arranged at intervals just above the surface of the feeding table 11, it is obvious that this will restrict the space just above the surface of the feeding table 11, making it inconvenient to place a new cardboard a on the surface of the cutting table 31. The feeding mechanism 10 adopts the method of placing the linear feeding power assembly 12 and the power seat 17 below the surface of the feeding table 11, leaving enough space above the surface of the feeding table 11 to facilitate the placement of new cardboard a on the surface of the cutting table 31.

[0048] Further, such as Figure 2 and Figure 3 As shown, two long holes 111 are arranged in parallel and spaced apart, and two material pushing swing rods 13 are arranged to penetrate the two long holes 111 respectively, and the two material pushing swing rods 13 are hinged on the power seat 17 through the same horizontal hinge axis. The two long holes 111 and two material pushing swing rods 13 are arranged in parallel and spaced apart, and the two material pushing swing rods 13 are in contact with the paperboard at two points, which improves the stability of the paperboard pushing process, so that the long holes 111 and the material pushing swing rods 13 do not need to be arranged in a large width structure, and the bearing capacity of the surface of the feeding table 11 is guaranteed.

[0049] On the basis of the above, if Figure 2 and Figure 3 As shown, an end baffle 14 is installed on the table surface of the feeding table 11. The end baffle 14 is used to position the starting end of the new cardboard a against the pushing side of the pushing swing rod 13. The end baffle 14 is located at the rear side of the initial position of the pushing swing rod 13 when the pushing swing rod 13 performs the forward motion, so that when the pushing swing rod 13 performs the avoidance rotation motion and moves to the initial position, there is a reset space between the initial position and the starting end of the new cardboard a for the pushing swing rod 13 to rotate and reset. The setting of the end baffle 14 accurately positions the end of the new cardboard a on the table surface of the feeding table 11, and at the same time, prevents the new cardboard a from being pushed by the pushing swing rod 13 when the weight is insufficient, thereby ensuring that the reset space is sufficient for the pushing swing rod 13 to rotate and reset.

[0050] Further, such as Figure 2 and Figure 3 As shown, the position of the end baffle 14 along the cardboard conveying direction is adjustable, so that different placement positions of the initial ends of the cardboards can be located according to cardboards of different sizes.

[0051] On the basis of the above, if Figure 2 and Figure 3 As shown, side baffles 15 are installed on both sides of the feeding table 11 in the conveying direction of the cardboard, which can ensure that the two sides of the cardboard are accurately positioned during the movement.

[0052] Furthermore, the two side baffles 15 are driven by the adjustment mechanism and can move closer or further away from each other, thereby adapting to paperboards of different widths.

[0053] Furthermore, the inner side wall of the side baffle 15 is a smooth and glossy structure, which reduces the friction between the cardboard and the side baffle 15 during the sliding process.

[0054] 2. Cutting mechanism 30

[0055] like Figure 1 and Figure 4-7 As shown, a shaping cutter 321 driven by a cutting power assembly 35 and performing a lifting action is arranged directly above the cutting table 31 of the cutting mechanism 30. The cutting power assembly 35 can be a vertically arranged air cylinder or hydraulic cylinder. The shaping cutter 321 is a closed frame structure that penetrates from top to bottom, and the inner peripheral contour of the shaping cutter 321 is adapted to the outer peripheral contour of the cut cardboard b, so that when the shaping cutter 321 cuts the cardboard, it can be cut and formed at one time. In addition, a lifting mechanism 36 is also provided on the cutting table 31, and the lifting part is located directly below the cut cardboard b. The lifting part can slide through the table surface of the cutting table 31, and when the lifting part performs an ascending action, the cut cardboard b is pushed upward along the inner cavity wall of the shaping cutter 321, thereby realizing a rapid dislocation separation between the cut cardboard b and the waste material, without the need to manually separate the cut cardboard b and the waste material, thereby improving the efficiency of cardboard processing.

[0056] On the basis of the above, if Figure 4 As shown, a knife seat 32 is fixed to the lifting end of the cutting power assembly 35, and the shaping cutter 321 is detachably fixed on the knife seat 32. The knife seat 32 and the space directly above the inner cavity of the shaping cutter 321 avoid each other. This detachable structure is not only convenient for the maintenance of the shaping cutter 321, but also can adapt to cardboards with different outer contours by disassembling and replacing different shaping cutters 321, thereby improving the adaptability of the cutting mechanism 30.

[0057] It is worth mentioning that Figure 4As shown, a material ejection pressing plate 33 is arranged just above the inner cavity of the shaping cutter 321. The material ejection pressing plate 33 is driven by a material ejection pressing power assembly 34 and performs a reciprocating lifting action. The material ejection pressing power assembly 34 can be a cylinder or a hydraulic cylinder. When working, the material ejection pressing plate 33 is used to press the top of the cut cardboard b before the lifting part of the ejection mechanism 36 ejects the cut cardboard b, and when the lifting top moves upward to eject the cut cardboard b, the material ejection pressing plate 33 moves upward synchronously. When the cut cardboard b is a multi-layer stacked structure, the cut cardboard b is effectively prevented from being scattered during the ejection process. In actual implementation, the material ejection pressing plate 33 can be made of elastic material or connected to the material ejection pressing power assembly 34 through an elastic member. When there is an error in the upward synchronous movement of the material ejection pressing power assembly 34 and the lifting part, the elastic force of the material ejection pressing plate 33 itself or the elastic force of the elastic member can ensure the stable pressing of the top of the cut cardboard b.

[0058] On the basis of the above, if Figure 6 and Figure 7As shown, the ejection mechanism 36 includes a stop plate 364 arranged horizontally on the plate surface and an ejection column 361 that vertically slides through the stop plate 364. The ejection columns 361 are arranged to be distributed in a dot matrix in a vertical viewing angle. In an initial state, the top ends and bottom ends of all the ejection columns 361 are flush with each other, and all the ejection columns 361 together constitute a lifting part; the stop plate 364 is located below the cutting table 31 for cutting paperboard, and the cutting table 31 has a through hole corresponding to each ejection column 361. In an initial state, the top end of the ejection column 361 is flush with or lower than the surface of the cutting table 31. A lifting plate 365 is arranged directly below the lifting column 361, and the plate surface is arranged horizontally and can be lifted and lowered to lift the lifting column 361. The lifting plate 365 is provided with a bypass hole 3651 for each lifting column 361 to pass through, and a push block 367 for blocking the bypass hole 3651 is detachably fixed in the bypass hole 3651. When the cardboard needs to be cut into other shapes, the cutting mechanism 30 replaces the shape cutter 321 whose inner circumference is adapted to the shape. At this time, in order to prevent the lifting column 361 from interfering with the outer peripheral contour of the replaced shape cutter 321, the push block 367 below the lifting column 361 whose lifting path interferes with the outer peripheral contour of the shape cutter 321 is removed. At this time, when the lifting plate 365 moves upward, the interfering lifting column 361 will pass through the bypass hole 3651 on the lifting plate 365, so that the lifting column 361 will not produce an upward lifting action. In addition, to ensure that the ejecting column 361 can increase the number of cut cardboards b as much as possible, all the avoidance sockets 3651 below the ejecting column 361 in the inner peripheral area of ​​the shaping cutter 321 are installed with push blocks 367. Compared with the traditional method of directly lifting the cut cardboard b through a specific shaping lifting plate 365, the ejecting mechanism 36 does not need to replace the ejecting plate, but only needs to install and remove the push blocks 367 in some of the avoidance sockets 3651, so that the abutted surfaces of paper boxes or cardboards of different external dimensions can be evenly squeezed during the ejecting process, which is not only convenient to operate, but also effectively reduces the adjustment cost. Of course, the ejecting mechanism 36 is not only suitable for the cutting mechanism 30 in the present application, but also can be adapted to other processes of cardboard processing, such as when the cardboard needs to be lifted in some stacking processes.

[0059] Furthermore, in order to further improve the convenience of disassembly and assembly of the push block 367, as Figure 6 and Figure 7As shown, the push block 367 is a two-stage shaft structure, the small shaft section of the push block 367 is plugged into the avoidance socket 3651, the large shaft diameter section of the push block 367 is larger than the diameter of the avoidance socket 3651, and the large shaft diameter section is arranged above the lifting plate 365 to form a blockage for the avoidance socket 3651; when the lifting plate 365 moves downward to the limit position, there is a disassembly gap 368 between the lifting plate 365 and the ejection column 361 for the push block 367 to pass through. When installing a new push block 367, the push block 367 is moved to the top of the lifting plate 365 through the disassembly gap 368 until it is moved to the corresponding avoidance socket 3651 and aligned. At this time, the push block 367 is loosened so that the small shaft diameter end of the push block 367 is inserted into the avoidance socket 3651 to complete the installation of the push block 367. Anyway, when disassembling the push block 367, it is only necessary to slide the small diameter section of the push block 367 upward out of the avoidance socket 3651 and take it out through the disassembly gap 368. The disassembly and assembly method of the push block 367 is efficient and convenient, and effectively improves the efficiency of disassembly and assembly of the push block 367. Of course, in actual implementation, the avoidance socket 3651 can be a threaded hole, and the push block 367 is screwed from the bottom of the lifting plate 365 to the inside of the avoidance socket 3651 to complete the installation.

[0060] On the basis of the above, if Figure 6 and Figure 7 As shown, a vertically distributed guide column 366 is fixed to the bottom of the stop plate 364, and the guide columns 366 are arranged in a rectangular array of four in a vertical perspective. The four corners of the lifting plate 365 are respectively slidably matched with the four guide columns 366 through linear bearings, thereby ensuring the stability of the lifting and sliding of the lifting plate 365.

[0061] In addition, if Figure 7 As shown, a lifting power assembly 362 for performing a vertical lifting action is arranged directly below the lifting plate 365. The lifting power assembly 362 can be a straight-stroke driving structure such as a cylinder, a hydraulic cylinder, or a screw slider mechanism. The lifting end of the lifting power assembly 362 is fixed to at least two separated edges of the lifting plate 365 through a lifting frame 3621, so that the driving force of the lifting power assembly 362 on the lifting plate 365 is more uniform, effectively preventing the lifting plate 365 from tilting during the lifting process.

[0062] On the basis of the above, a limit stopper 3611 is fixed on the rod between the stop plate 364 and the cutting table 31 on the material ejecting column 361. In the initial state, the bottom of the limit stopper 3611 is in contact with the top of the stop plate 364, so that the material ejecting column 361 can slide downward to the limit position under gravity. In addition, a return spring 363 is sleeved on the rod between the limit stopper 3611 and the cutting table 31 on the material ejecting column 361 to assist the material ejecting column 361 in sliding downward under the action of gravity and prevent the material ejecting column 361 from getting stuck during the downward return process.

[0063] 3. Transfer agency 20

[0064] like Figure 1 Figure 4 and Figure 5 and Figure 8 As shown, the transport mechanism 20 transports the cut cardboard b ejected by the ejection mechanism 36, and the transport mechanism 20 includes a transport seat 22 driven by a transport transmission assembly 21 and performing horizontal linear reciprocating motion, and the transport transmission assembly 21 can be a linear motion power mechanism such as a screw slider mechanism, a cylinder or a hydraulic cylinder. A supporting member is fixed on the transport seat 22. When the lifting part ejects the cut cardboard b, the upper part of the lifting part protrudes above the molding cutter 321, and the movement path of the supporting member and the upper part of the lifting part are misaligned with each other and intersect with the directly below the ejected cut cardboard b. When in use, the supporting member moves to the bottom of the cut cardboard b, and thereafter, the lifting part slides downward, and the supporting member replaces the lifting part to support the cut cardboard b. At this time, the transport seat 22 with the transport transmission assembly 21 moves, and the transport work of the cut cardboard b can be realized.

[0065] Further, such as Figure 8 As shown, a transfer pressing plate 23 for pressing the cut cardboard b is arranged directly above the supporting member. The transfer pressing plate 23 is driven by a transfer pressing power assembly 24 on the transfer seat 22 to perform lifting and lowering movements. The transfer pressing power assembly 24 can be a linear motion power mechanism such as a screw slider mechanism, a cylinder or a hydraulic cylinder. When the supporting member supports the cut cardboard b, the transfer pressing plate 23 is used to press the top of the cut cardboard b, which can prevent the cardboard b from falling from the supporting member during transportation, and also prevent the cut cardboard b from spreading during transportation when the cut cardboard b is a multi-layer structure.

[0066] Further, such as Figure 3 and Figure 5 As shown, the supporting member is a supporting rod 25 arranged in a length direction parallel to the horizontal linear reciprocating motion direction of the transfer seat 22, and the supporting rod 25 is arranged as at least two parallel and spaced apart. The rod-shaped structure of the supporting rod 25 is convenient for the lifting part, and the design of at least two supporting rods 25 can also achieve stable support for the bottom of the cut cardboard b. It is worth mentioning that the structural design of the supporting rod 25, combined with the above-mentioned plurality of ejecting columns 361 distributed in a dot matrix in the vertical perspective to form the form of the lifting part, the supporting rod 25 only needs to align the movement path with the row and column gap or the longitudinal column gap of the ejecting column 361.

[0067] 4. Transfer agency 40

[0068] like Figure 8 and Fig. 9As shown, the transfer mechanism 40 is used to receive the cut cardboard b, and the transfer mechanism 40 includes a transfer table, which is composed of at least three strip surfaces arranged in parallel and spaced apart. In the embodiment where the supporting member is at least two supporting rods 25, the horizontal linear reciprocating motion direction of the transfer seat 22 is parallel to the length direction of the strip surface, and at least two supporting rods 25 are respectively inserted into the intervals between adjacent strip surfaces. The transfer mechanism 20 also includes a discharge lifting transmission assembly 26 that can drive the transfer seat 22 to perform lifting motion. The discharge lifting transmission assembly 26 can be a linear motion power mechanism such as a screw slider mechanism, a cylinder or a hydraulic cylinder. The transfer table of the transfer mechanism 40 adopts the form of a strip surface with intervals to avoid the supporting rods 25. When the supporting rods 25 move the cut cardboard b to the top of the transfer table, when the unloading lifting transmission assembly 26 drives the transfer seat 22 to move downward, the supporting rods 25 slide to the interval of the strip surface and stably place the cut cardboard b on the supporting rods 25 on the strip surface.

[0069] On the basis of the above, if Figure 8 and Fig. 9 As shown, the transfer mechanism 40 also includes a mounting frame 42, on which a belt conveyor assembly 43 driven by a belt motor 44 is mounted. The belt conveyor assembly 43 is arranged in at least three groups that are parallel and spaced apart, and the upper surface of the belt of the belt conveyor assembly 43 forms a strip surface; the transfer mechanism 20 is arranged adjacent to the conveying start end of the belt conveyor assembly 43. In the form of the upper surface of the belt of the belt conveyor assembly 43 forming a strip surface, when the transfer mechanism 20 places the cut cardboard b at the start end of the belt conveyor assembly 43, the belt conveyor assembly 43 is rotated by a certain angle to transport the cut cardboard b to the end of the belt conveyor assembly 43, and multiple groups of materials can be accumulated on the transfer platform at one time before being stacked, so as to realize the one-time synchronous stacking of multiple groups of materials; in addition, in the process of accumulating multiple groups of materials on the transfer platform, a longer time is reserved for the stacking operation, so that when the time required for cutting and transporting the cardboard is less than the time required for stacking, there is no need to wait for the stacking operation to be completed after cutting and transporting, which effectively improves the production efficiency of cardboard processing.

[0070] In addition, if Fig. 9 As shown, the transmission wheels on the same side of all the belt conveyor assemblies 43 are fixed by the same shaft rod, and the vertical space between the top side of the shaft rod and the upper surface of the belt of the belt conveyor assembly 43 can be used for the support rod 25 to be inserted, ensuring that all the belt conveyor assemblies 43 rotate synchronously to achieve stable transportation of the cut cardboard b.

[0071] Further, such as Figure 8-10As shown, a vertically arranged stop bar 45 is arranged at the conveying end of the belt conveying assembly 43 to prevent the cut cardboard b from falling from the conveying end of the belt conveying assembly 43. Since the stop bar 45 cannot avoid a gap with the conveying end of the belt conveying assembly 43 when it is arranged vertically, the cut cardboard b may fall through the gap, so it is necessary to process the gap. Fig.10 As shown, a horizontal support bar 451 is fixed on one side of the stop bar 45 close to the belt conveyor assembly 43, and the cantilever end of the horizontal support bar 451 is arranged adjacent to the conveying end of the belt conveyor assembly 43, and the end of the cut cardboard b conveyed to the end of the belt conveyor assembly 43 is carried by the horizontal support bar 451. The upper surface of the horizontal support bar 451 is lower than the upper surface of the belt of the belt conveyor assembly 43. The arrangement of the horizontal support bar 451 allows the front end of the cut cardboard b to stably fall onto the horizontal support bar 451 after being separated from the belt conveyor assembly 43. In this embodiment, the outer surface of the belt of the belt conveyor assembly 43 can be made of a smooth low-damping material to prevent the outer surface of the belt of the belt conveyor assembly 43 from having too much friction with the cut cardboard b, thereby preventing the front end of the cut cardboard b from colliding with the stop bar 45 and flipping.

[0072] It is worth mentioning that the transfer mechanism 40 may also include a waste box 41, the transfer platform is arranged directly above the waste box 41, and the waste box 41 and the feed table 11 are arranged at both ends of the cutting table 31. The waste box 41 is open at the top, and the height of the top opening of the waste box 41 is lower than the top surface height of the cutting table 31; when the feed table 11 continuously supplies new cardboard a to the cutting table 31, the waste remaining on the cutting table 31 will be pushed forward, and when the waste moves to the top opening of the waste box 41, it will automatically fall into the inside of the waste box 41, completing the automatic collection of the waste after cutting, which effectively improves the convenience of collecting the waste after cutting.

[0073] 5. Palletizing mechanism 50

[0074] like Figure 11-12As shown, the stacking mechanism 50 is used for stacking the cut cardboards b on the transfer table of the transfer mechanism 40. The stacking mechanism 50 includes a stacking seat 53 and a stacking platform 56 distributed directly below the stacking seat 53. The stacking seat 53 is driven by a stacking horizontal power assembly 51 and a stacking lifting power assembly 52, respectively, and the stacking seat 53 is respectively made to perform horizontal reciprocating motion and vertical lifting motion. The stacking horizontal power assembly 51 and the stacking lifting power assembly 52 can be linear stroke power mechanisms such as screw slider mechanisms, cylinders or hydraulic cylinders, and finally the stacking seat 53 can be made to perform horizontal reciprocating motion and lifting motion. The stacking seat 53 is provided with a telescopic support part that can slide horizontally. The telescopic support part is driven by a telescopic power assembly 55 and can be retracted to the inside of the stacking seat 53. Similarly, the telescopic power assembly 55 can be a linear power mechanism such as a screw slider mechanism, a cylinder or a hydraulic cylinder. The movement path of the telescopic support part is offset from the transfer table in the vertical angle, and can be moved to the bottom of the cut cardboard b to lift the cut cardboard b and separate it from the transfer table. When working, the telescopic support part is moved to the bottom of the cut cardboard b by the stacking horizontal power assembly 51, and then the stacking lifting power assembly 52 drives the telescopic support part to move upward to separate the cut cardboard b from the transfer table. Afterwards, the stacking horizontal power assembly 51 drives the supporting telescopic part and the cut cardboard b to move to the designated area on the stacking platform 56, and the stacking lifting power assembly 52 lifts the supporting telescopic part and the cut cardboard b to the designated stacking height. At this time, the telescopic power assembly 55 drives the supporting telescopic part to retract into the stacking seat 53, so that the cut cardboard b loses the support of the supporting telescopic part and falls to the designated position on the stacking platform 56, thereby realizing the automatic stacking of the cardboard b. In the specific implementation, the designated area and the designated stacking height are determined according to the external dimensions of the cut cardboard b, and the automatic stacking operation is realized by relying on the controller of the prior art or the controller combined with the sensor. The content of the controller is the prior art and will not be repeated here.

[0075] In an embodiment where the transfer table is composed of at least three strip-shaped surfaces arranged in parallel and spaced apart, Fig.11 As shown, the horizontal reciprocating motion direction of the stacking seat 53 is parallel to the length direction of the strip surface, and the telescopic support part is an axially sliding and contracting telescopic plug rod 54, the length direction of the telescopic plug rod 54 is parallel to the length direction of the strip surface, and the telescopic plug rod 54 is at least two that can be inserted into the intervals between adjacent strip surfaces. The transfer table of the transfer mechanism 40 adopts the form of strip surfaces distributed at intervals to avoid the telescopic plug rod 54, and there is no need to set a large interval for avoiding the telescopic support part, which not only ensures uniform support for the bottom of the cut cardboard b, but also allows multiple telescopic plug rods 54 to be set accordingly, so that when the telescopic plug rod 54 lifts the cut cardboard b, it can also stably support the bottom of the cut cardboard b.

[0076] like Fig.11 As shown, the transfer mechanism 40 also includes a mounting frame 42, on which a belt conveyor assembly 43 driven by a belt motor 44 is mounted. The belt conveyor assembly 43 is arranged in at least three groups that are parallel and spaced apart. In an embodiment in which a strip surface is formed by the upper surface of the belt of the belt conveyor assembly 43, the stacking mechanism 50 is arranged adjacent to the conveying end of the belt conveyor assembly 43. The upper surface of the belt of the belt conveyor assembly 43 is formed in a strip-shaped form. When the transfer mechanism 20 places the cut cardboard b on the starting end of the belt conveyor assembly 43, the belt conveyor assembly 43 can be rotated by a certain angle to transport the cut cardboard b to the end of the belt conveyor assembly 43. Multiple groups of materials can be accumulated on the transfer platform at one time and then stacked by the stacking mechanism 50, thereby realizing one-time synchronous stacking of multiple groups of materials. In addition, in the process of accumulating multiple groups of materials on the transfer platform, a longer operating time is reserved for the stacking mechanism 50, so that when the time required for cardboard cutting and transfer is less than the time required for the stacking mechanism 50, there is no need to wait for the stacking mechanism 50 to complete the operation after cutting and transfer, thereby effectively improving the production efficiency and production continuity of cardboard processing.

[0077] like Fig. 9 As shown, the transmission wheels on the same side of all the belt conveyor assemblies 43 are fixed by the same shaft rod, and the vertical space between the top side of the shaft rod and the upper surface of the belt of the belt conveyor assembly 43 can be inserted into the telescopic rod 54, ensuring that all the belt conveyor assemblies 43 rotate synchronously to achieve stable transportation of the cut cardboard b.

[0078] like Fig.10 As shown, the tabletop of the stacking platform 56 is a rectangular structure, and the long side direction of the rectangle is parallel to the horizontal reciprocating direction of the stacking seat 53, so that multi-linear length stacking can be achieved along the length direction of the stacking platform 56.

[0079] It is worth mentioning that the above-mentioned transfer mechanism 20, transfer mechanism 40 and stacking mechanism 50 can be used together as a transfer stacking device in a cardboard cutting device. In actual implementation, the transfer stacking device can be provided with a stacking mechanism 50 alone to achieve transfer and stacking operations. It is only necessary to modify the stacking mechanism 50 to transfer the cut cardboard b on the transfer mechanism 40 to the cardboard on the lifting part of the cutting mechanism 30. Of course, using the stacking mechanism 50 to transfer and stack the cut cardboard alone will result in a longer overall stacking time, and the cutting mechanism 30 needs to wait for the stacking operation of the stacking mechanism 50.

[0080] In order to achieve efficient and continuous cutting and palletizing operations, the optimized cutting and palletizing method is further described below. The cutting and palletizing method includes the following steps:

[0081] S1, pushing the paperboard on the feeding table 11 through the pushing side of the pushing swing rod 13, so that a group of printed patterns on the front side of the paperboard moves to the cutting area of ​​the cutting table 31 of the cutting mechanism 30;

[0082] S2, using the shaping cutter 321 directly above the cutting table 31 to move downward, the shaping cutter 321 cuts the paperboard along the edge of the printed pattern to form a cut paperboard b;

[0083] S3, lifting the cut cardboard b upward through the lifting part of the lifting mechanism 36 directly below the cut cardboard b, and making the cut cardboard b move to above the shaping cutter 321;

[0084] S4, the transfer and stacking device transfers the cut cardboard b and stacks it according to the predicted strategy, and at the same time, the ejecting mechanism 36 is reset;

[0085] S5, the material pushing swing rod 13 pushes the paperboard forward again, and makes the cut waste deviate from the cutting area. At the same time, the group of printed patterns located at the front side moves to the cutting area;

[0086] S6, looping steps S2-S5, and when a placement area large enough to accommodate a new cardboard a is formed on the table surface of the feeding table 11 behind the pushing swing rod 13, the new cardboard a is positioned and placed in the placement area of ​​the feeding table 11, until the last group of printed patterns on the cardboard moves to the cutting area, the loop of steps S2-S5 is stopped, and a group of steps S2-S4 is continued. At the same time, the pushing swing rod 13 makes a return motion, and after the pushing swing rod 13 is reset and step S4 is completed, the process returns to step S1.

[0087] In the present cutting and stacking method, the feeding mechanism 10 places the new cardboard a in the placement area in advance when the pusher swing rod 13 follows the power seat 17 to perform the forward movement, and the pusher swing rod 13 can avoid the new cardboard a and reset when performing the return movement through the hinged design of the pusher swing rod 13. The new cardboard a is positioned and installed before the pusher swing rod 13 is reset, and the return reset of the pusher swing rod 13 is realized by utilizing the time interval between the cutting and transfer stacking of the last set of printed patterns, so there is no need to wait for the pusher swing rod 13 to return and reset after the cutting is completed, thereby preventing the continuous cutting operation of the cardboard from being interrupted, thereby ensuring the cardboard processing efficiency.

[0088] On the basis of the above, the prediction strategy in step S4 of the present cutting and stacking method is specifically that the transfer mechanism 20 transfers the cut cardboard b to the transfer mechanism 40, and after the transfer mechanism 40 accumulates enough cut cardboard b, the stacking mechanism 50 stacks the cut cardboard b stored on the transfer mechanism 40 to the stacking platform 56. The form in which the transfer mechanism 20 accumulates the cut cardboard b on the transfer mechanism 40 enables the stacking mechanism 50 to transfer multiple groups of materials in one operation; at the same time, during the accumulation of the cut cardboard b in the transfer mechanism 40, a longer operation time is reserved for the stacking mechanism 50, so that when the time required for cutting and transporting the cardboard is less than the time required for the stacking mechanism 50, there is no need to wait for the stacking mechanism 50 to complete the operation after cutting and transporting, which effectively improves the production efficiency and production continuity of cardboard processing.
