Description

TECHNICAL FIELD

[0001] The utility model relates to paperboard processing technical field, and specifically is a kind of paperboard cutting processing feeding mechanism. BACKGROUND

[0002] The paper box is a three-dimensional modeling, and it is a polyhedral body composed of the movement, accumulation, folding and surrounding of a plurality of faces.

[0003] The cutting processing of paperboard is one of the main processes of paper box processing. A feeding mechanism is often provided at the front end of the cutting mechanism for cutting processing to supply paperboard raw materials to the cutting mechanism. As described in the text of the cutting equipment for paper box production with automatic feeding function of the patent with publication number CN115139567A, the paperboard is automatically transported by the belt, so that the paperboard smoothly reaches the surface of the cutting face, thereby enabling the cutting to cut the paperboard above the cutting face.

[0004] The above-mentioned belt conveying mode can efficiently realize the continuous conveying of paperboard raw materials, but the paperboard and the belt only rely on friction force for transmission, and the relative movement between the paperboard and the belt makes it difficult to realize accurate conveying of the paperboard. In the cutting operation of paper boxes such as cigarette boxes, the cutting operation needs to be accurately cut according to the edge of the printed pattern on the paperboard. In addition, since the size of the cigarette box is small, multiple printed patterns are often arranged on a piece of paperboard, so that the paperboard needs to be accurately pushed forward multiple times during the cutting process. Obviously, the belt conveying mode often cannot meet the requirements. Although the straight stroke mechanism can drive the push plate to accurately push the paperboard multiple times in the prior art, the push plate needs to be reset and then the new paperboard is positioned and placed on the feeding platform after the multiple printed patterns on the paperboard are cut. Then the continuous conveying operation of the paperboard is performed. Obviously, the resetting and positioning of the push plate after the cutting operation of the paperboard is interrupted, which affects the processing efficiency of the paperboard, and therefore needs to be solved. UTILITY MODEL CONTENTS

[0005] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a feeding mechanism for paperboard cutting processing, which can accurately and efficiently realize the continuous feeding of paperboard.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] The application discloses a feeding mechanism for paperboard cutting processing, which comprises a feeding table, a power seat driven by a straight stroke feeding power assembly and capable of making reciprocating linear motion along a paperboard conveying direction, a pushing material swing rod hinged to the power seat through a horizontal hinge shaft perpendicular to the paperboard conveying direction, a normal state of the pushing material swing rod being vertical arrangement, a front side of the pushing material swing rod being a pushing material side and a rear side being a reverse pushing side, a rotation stopping block fixed to the power seat, the pushing material side of the pushing material swing rod pushing the paperboard in a placing area on the feeding table when the pushing material swing rod makes feeding progress action, and the pushing material swing rod generating a torsional abutting force with the rotation stopping block to maintain the vertical arrangement of the pushing material swing rod; when the pushing material swing rod moves to the rear of the placing area and makes return action, new paperboard on the placing area abuts against the reverse pushing side of the pushing material swing rod, and the pushing material swing rod generates an avoiding rotation action to avoid the new paperboard.

[0008] As a further scheme of the application, a torsional spring rotating shaft is installed on the horizontal hinge shaft, and the torsional spring rotating shaft generates an elastic pushing force to push the pushing material swing rod and the rotation stopping block to abut against each other when the torsional spring rotating shaft releases energy, so as to maintain the vertical arrangement of the pushing material swing rod.

[0009] As a further scheme of the application, a long hole is formed in the table top of the feeding table and penetrates the table top upward and downward, the hole type length direction of the long hole is parallel to the conveying direction of the paperboard, the straight stroke feeding power assembly and the power seat are located below the feeding table, the upper end of the pushing material swing rod penetrates the long hole vertically and protrudes above the feeding table in the normal state, and the upper end of the pushing material swing rod forms a pushing part for pushing the paperboard to slide.

[0010] As a further scheme of the application, the long hole is provided as two parallel and spaced long holes, the pushing material swing rod is provided as two rods penetrating the two long holes respectively, and the two rods are hinged to the power seat through the same horizontal hinge shaft.

[0011] As a further scheme of the application, an end baffle is installed on the table top of the feeding table, the end baffle is used for positioning a starting end of the new paperboard abutting against the pushing material side of the pushing material swing rod, the end baffle is located at the rear side of an initial position of the pushing material swing rod making progress action, so that when the pushing material swing rod makes the avoiding rotation action and moves to the initial position, a reset space for the pushing material swing rod to rotate back is provided between the initial position and the starting end of the new paperboard.

[0012] As a further scheme of the application, the position of the end baffle along the conveying direction of the paperboard is adjustable.

[0013] As a further scheme of the application, side baffles are installed on both sides of the feeding table along the conveying direction of the paperboard.

[0014] As a further improvement of this utility model, the two side baffles are driven by an adjustment mechanism and can move closer together or further apart.

[0015] As a further improvement of this utility model, the inner wall of the side baffle has a smooth, flat surface.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. During the material feeding mechanism's pusher arm's movement in tandem with the power unit, new cardboard is placed in the placement area beforehand. The hinged design of the pusher arm allows it to avoid the new cardboard and reset during its return stroke. The new cardboard is positioned and installed before the pusher arm resets, and the return stroke is achieved during the time interval between the last set of printed pattern cutting and transfer stacking. This eliminates the need to wait for the pusher arm to return after cutting, preventing interruptions to continuous cardboard cutting operations and ensuring efficient cardboard processing.

[0018] 2. A torsion spring shaft is installed on the horizontal hinge shaft. When the torsion spring shaft releases energy, it generates an elastic thrust that pushes the pusher arm to abut against the anti-rotation block, ensuring that the pusher arm quickly resets after making an avoidance rotation action and maintains a stable vertical arrangement of the pusher arm.

[0019] 3. The feeding mechanism adopts a linear feeding power unit and power base located below the feeding table surface, leaving enough space above the feeding table surface to facilitate the placement of new cardboard on the cutting table surface.

[0020] 4. The end baffle is set to accurately position the end of the new cardboard on the feeding table. At the same time, it prevents the pusher arm from being pushed when the new cardboard is not heavy enough, thus ensuring that there is enough space for the pusher arm to rotate and reset.

[0021] 5. Side baffles are installed on both sides of the feeding platform in the direction of cardboard conveying to ensure accurate positioning of the cardboard on both sides during movement. Attached Figure Description

DETAILED DESCRIPTION

[0035] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0036] For the convenience of understanding, the specific structure and working mode of the present application will be further described below in combination with the drawings:

[0037] The general assembly structure of the corresponding production line of the present application specifically refers to Figures 1-12 The main structure of the corresponding production line of the present application includes a feeding mechanism 10, a transfer mechanism 20, a cutting mechanism 30, a transfer mechanism 40 and a stacking mechanism 50. Since the content of the present application is associated with the content of the corresponding production line, the content of the present application will be described in detail below by describing each mechanism in the production line in detail.

[0038] 1. Feeding mechanism 10

[0039] As shown in Figure 1 , the feeding mechanism 10 is arranged at one end of the cutting mechanism 30 and is used for continuously feeding the cutting mechanism 30. Specifically, as shown in Figure 2 and Figure 3 , the feeding mechanism 10 includes a feeding table 11, the feeding table 11 is provided with a power seat 17 driven by a straight stroke feeding power assembly 12 and capable of reciprocating linear motion along the paperboard conveying direction. Specifically, the straight stroke feeding power assembly 12 can be a screw block mechanism or a cylinder; the power seat 17 is hinged with a pushing lever 13 through a horizontal hinge shaft perpendicular to the paperboard conveying direction. In normal state, the pushing lever 13 is vertically arranged, the front side of the pushing lever 13 moving with the power seat 17 is a pushing side, and the rear side is a counter pushing side; the power seat 17 is fixed with a rotation stop block 16 for keeping the pushing lever 13 in vertical arrangement when the pushing lever 13 moves. Specifically, when the pushing lever 13 moves to feed, the pushing side of the pushing lever 13 pushes the paperboard in the placing area on the feeding table 11, and the pushing lever 13 generates a torsional abutting force with the rotation stop block 16 to maintain the vertical arrangement of the pushing lever 13; when the pushing lever 13 moves to the rear of the placing area and moves back, the new paperboard a on the placing area abuts against the counter pushing side of the pushing lever 13, and the pushing lever 13 generates an avoidance turning action to avoid the new paperboard a.

[0040] In use, at the beginning of the production line, the pushing and swinging lever 13 is reset to the initial position of the process action, at this time, the paperboard can be positioned and placed in the placement area of the feeding table 11, during the operation of the production line, the straight stroke feeding power assembly 12 drives the power seat 17 and the pushing and swinging lever 13 to perform the process action, so as to push the paperboard to the cutting area of the cutting mechanism 30 for cutting. No matter how many groups of printed patterns are arranged on the paperboard, when the last group of printed patterns on the paperboard is pushed to the cutting area, the pushing and swinging lever 13 will move to the rear of the placement area, at this time, the new paperboard a can be positioned and placed in the placement area; after the last group of printed patterns is pushed to the cutting area, the pushing and swinging lever 13 performs the return action with the power seat 17, the new paperboard a on the placement area abuts against the anti-pushing side of the pushing and swinging lever 13, and the pushing and swinging lever 13 generates the avoidance rotating action to avoid the new paperboard a, so that the pushing and swinging lever 13 can be reset to the initial position again after the new paperboard a is placed in the placement area. In the process of the pushing and swinging lever 13 performing the process action with the power seat 17, the feeding mechanism 10 places the new paperboard a in the placement area in advance, and through the hinged design of the pushing and swinging lever 13, the pushing and swinging lever 13 can avoid the new paperboard a and reset when performing the return action, which does not cause the interruption of the continuous cutting operation of the paperboard, thereby ensuring the paperboard processing efficiency.

[0041] Further, in order to ensure that the pushing and swinging lever 13 resets quickly after performing the avoidance rotating action and maintains the stable vertical arrangement of the pushing and swinging lever 13, a torsion spring rotating shaft is installed on the horizontal hinge shaft, and the torsion spring rotating shaft generates the elastic pushing force to push the pushing and swinging lever 13 to abut against the rotation stopping block 16 when releasing energy. Of course, in actual implementation, the pushing and swinging lever 13 can adopt the form of light upper end and heavy lower end, and the pushing and swinging lever 13 itself maintains the stable vertical arrangement by using the gravity of the pushing and swinging lever 13.

[0042] On the basis of the above, Figure 2 and Figure 3As shown, the feeding table 11 is provided with a long hole 111 vertically penetrating the table top, and the hole length direction of the long hole 111 is parallel to the paperboard conveying direction; the straight stroke feeding power assembly 12 and the power seat 17 are located below the feeding table 11, and the upper end of the pushing swing lever 13 vertically penetrates the long hole 111 and protrudes above the feeding table 11 in the normal state, and the upper end of the pushing swing lever 13 forms a pushing part for pushing the paperboard to slide. Although in actual implementation, the straight stroke feeding power assembly 12 and the power seat 17 can be arranged in a spaced manner above the feeding table 11, obviously, the space above the feeding table 11 will be restricted, and it is inconvenient to place the new paperboard a on the table top of the cutting table 31. In the feeding mechanism 10, the straight stroke feeding power assembly 12 and the power seat 17 are arranged below the feeding table 11, which leaves enough space above the feeding table 11, and facilitates the placement of the new paperboard a on the table top of the cutting table 31.

[0043] Further, as shown in Figure 2 and Figure 3 , the long hole 111 is arranged in parallel and spaced apart, and the pushing swing lever 13 is arranged to penetrate the two long holes 111, and the two pushing swing levers 13 are hinged to the power seat 17 through the same horizontal hinge shaft. The two long holes 111 and the two pushing swing levers 13 are arranged in parallel and spaced apart, and the two pushing swing levers 13 contact and abut the paperboard at two points, which improves the stability of the pushing process of the paperboard, so that the long hole 111 and the pushing swing lever 13 do not need to be arranged in a large width configuration, and the load bearing capacity of the table top of the feeding table 11 is guaranteed.

[0044] On the basis of the above, as shown in Figure 2 and Figure 3 , an end baffle 14 is installed on the table top of the feeding table 11, and the end baffle 14 is used to position the starting end of the new paperboard a abutting the pushing side of the pushing swing lever 13. The end baffle 14 is located at the rear side of the initial position of the pushing swing lever 13, so that when the pushing swing lever 13 performs a turning action and moves to the initial position, the initial position and the starting end of the new paperboard a have a reset space for the turning reset of the pushing swing lever 13. The end baffle 14 accurately positions the position of the end of the new paperboard a on the table top of the feeding table 11, and at the same time, prevents the new paperboard a from being pushed by the pushing swing lever 13 performing a return action when the weight of the new paperboard a is insufficient, thereby ensuring that the reset space is sufficient for the turning reset of the pushing swing lever 13.

[0045] Further, as shown in Figure 2 and Figure 3 , the position of the end baffle 14 along the paperboard conveying direction is adjustable, so that different placement positions of the initial end of the paperboard can be positioned according to different sizes of the paperboard.

[0046] On the basis of the above, as shown in Figure 2 andFigure 3 As shown, the side plates 15 are installed on both sides of the feeding table 11 in the paperboard conveying direction, which can ensure accurate positioning of the paperboard on both sides during movement.

[0047] Further, the two side plates 15 are driven by an adjusting mechanism and can move close to and away from each other, thereby adapting to paperboards of different widths.

[0048] Further, the inner side wall of the side plate 15 is flat and smooth, reducing friction between the paperboard and the side plate 15 during sliding.

[0049] 2, cutting mechanism 30

[0050] As shown in Figure 1 and Figures 4-7 , a shaped cutting knife 321 driven by a cutting power assembly 35 and performing lifting action is arranged 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 shaped cutting knife 321 is in a closed frame structure passing through up and down, and the inner peripheral contour of the shaped cutting knife 321 is adapted to the outer peripheral contour of the cut paperboard b, so that when the shaped cutting knife 321 cuts the paperboard, it can cut the cut paperboard b at one time. In addition, the cutting table 31 is also provided with a stripping mechanism 36 whose lifting part is located below the cut paperboard b. The lifting part can slide through the surface of the cutting table 31 and when the lifting part rises, the cut paperboard b is pushed upwards along the inner cavity wall of the shaped cutting knife 321, thereby realizing the rapid dislocation separation between the cut paperboard b and the waste, without the need for manual separation of the cut paperboard b and the waste, improving the efficiency of paperboard processing.

[0051] Based on the above, as shown in Figure 4 , the lifting end of the cutting power assembly 35 is fixed with a tool holder 32, and the shaped cutting knife 321 is detachably fixed on the tool holder 32. The tool holder 32 and the inner cavity of the shaped cutting knife 321 are spaced from each other. This detachable structure not only facilitates the maintenance of the shaped cutting knife 321, but also through the disassembly and replacement of different shaped cutting knives 321, it can also adapt to paperboards of different shapes and contours, improving the adaptability of the cutting mechanism 30.

[0052] It is worth mentioning that, as shown in Figure 4As shown, the inner cavity of the shaping cutter 321 is arranged above a material ejection pressing plate 33, the material ejection pressing plate 33 is driven by a material ejection pressing power assembly 34 and performs reciprocating lifting action, the material ejection pressing power assembly 34 can be a pneumatic cylinder or a hydraulic cylinder. During work, the material ejection pressing plate 33 presses the top of the cut paper board b by the lifting part of the material ejection mechanism 36, and when the top is lifted to move upward to eject the cut paper board b, the material ejection pressing plate 33 moves upward synchronously, which effectively prevents the cut paper board b 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 element, when there is an error in the synchronous upward movement of the material ejection pressing power assembly 34 and the lifting part, the elastic force of the material ejection pressing plate 33 or the elastic element can ensure the stable pressing of the top of the cut paper board b.

[0053] On the basis of the above, Figure 6 and Figure 7As shown, the ejection mechanism 36 comprises a horizontally arranged stop plate 364 and ejection columns 361 vertically sliding through the stop plate 364, the ejection columns 361 are arranged in a lattice pattern in the vertical view, and the top ends and the bottom ends of all the ejection columns 361 are horizontally flush in the initial state, and all the ejection columns 361 together form a lifting part; the stop plate 364 is located below the cutting table 31 for cutting the paperboard, and the cutting table 31 has a through hole corresponding to each ejection column 361, and in the initial state, the top end of the ejection column 361 is flush with or lower than the table surface of the cutting table 31. The ejection columns 361 are vertically below the lifting plate 365 which is horizontally arranged and can be lifted to lift the ejection columns 361, and the lifting plate 365 is provided with an avoidance plug hole 3651 for each ejection column 361 to pass through, and the avoidance plug hole 3651 is detachably fixed with a push block 367 which blocks the avoidance plug hole 3651. When the paperboard needs to be cut into other shapes, the cutting mechanism 30 replaces the shape cutter 321 which is adapted to the shape, at this time, in order to prevent the ejection columns 361 from interfering with the outer contour of the replaced shape cutter 321, the push block 367 below the ejection column 361 which interferes with the lifting path and the outer contour of the shape cutter 321 is removed, at this time, when the lifting plate 365 moves upward, the interfering ejection column 361 will pass through the avoidance plug hole 3651 on the lifting plate 365, so that the ejection column 361 will not produce upward ejection action. In addition, in order to ensure that the ejection columns 361 can increase the number of cut paperboards b as much as possible, the avoidance plug holes 3651 below the ejection columns 361 in the inner circumferential area of the shape cutter 321 are all installed with push blocks 367, compared with the traditional method of directly lifting the cut paperboard b by a specific shape lifting plate 365, the ejection mechanism 36 does not need to replace the ejection plate, only needs to install and remove the push block 367 in part of the avoidance plug hole 3651, which can uniformly press the abutted surface of the paper box or paperboard with different outer dimensions in the ejection process, not only convenient to operate, but also effectively reduces the adjustment cost. Of course, the ejection mechanism 36 is not only suitable for the cutting mechanism 30 in the application, but also can be applied in other processes of paperboard processing, such as the process of lifting the paperboard in part of the stacking process.

[0054] Further, in order to further improve the convenience of disassembling and assembling the push block 367, such as Figure 6 and Figure 7As shown, the push block 367 is in a two-section shaft structure, the small shaft section of the push block 367 is in plug-in cooperation with the escape hole 3651, the large shaft diameter section of the push block 367 is larger in diameter than the diameter of the escape hole 3651, and is arranged above the jacking plate 365 to form a blockage to the escape hole 3651; when the jacking plate 365 moves to the limit position, the jacking plate 365 and the material jacking column 361 have a disassembly gap 368 for the push block 367 to pass through. When installing a new push block 367, the push block 367 is moved through the disassembly gap 368 to be directly above the jacking plate 365, and then moved to be aligned with the corresponding escape hole 3651, at this time, the push block 367 is loosened and the small shaft end of the push block 367 is inserted into the escape hole 3651 to complete the installation of the push block 367. In the opposite way, when disassembling the push block 367, only the small shaft section of the push block 367 is slid upward out of the escape hole 3651, and then taken out through the disassembly gap 368. The disassembly method of the push block 367 is efficient and convenient, which effectively improves the disassembly efficiency of the push block 367. Of course, in actual implementation, the escape hole 3651 can be a threaded hole, and the push block 367 is screwed from below the jacking plate 365 to the inside of the escape hole 3651 to complete the installation.

[0055] On the basis of the above, Figure 6 and Figure 7 As shown, the bottom of the stop plate 364 is fixed with a plumb-distributed guide column 366, the guide column 366 is arranged in a rectangular array distribution of four in the vertical visual angle, and the four corners of the jacking plate 365 are respectively slidably connected with the four guide columns 366 through linear bearings, which ensures the stability of the jacking plate 365 in lifting and sliding.

[0056] In addition, as shown, Figure 7 The bottom of the jacking plate 365 is arranged with a material jacking power assembly 362 for performing plumb lifting action, which can be a straight stroke driving structure such as a gas cylinder, a hydraulic cylinder or a lead screw and sliding block mechanism. The lifting end of the material jacking power assembly 362 is fixed to at least two opposite sides of the jacking plate 365 through a jacking frame 3621, so that the driving force of the material jacking power assembly 362 to the jacking plate 365 is more uniform, effectively preventing the jacking plate 365 from tilting during lifting.

[0057] On the basis of the above, a limiting block 3611 is fixed on the rod between the stop plate 364 and the cutting table 31 on the material jacking column 361, in the initial state, the bottom of the limiting block 3611 is in contact with the top of the stop plate 364, realizing the positioning of the material jacking column 361 in the process of sliding downward to the limit position under the action of gravity. In addition, a reset spring 363 is sleeved on the rod between the limiting block 3611 and the cutting table 31 on the material jacking column 361, to assist the downward sliding of the material jacking column 361 under the action of gravity, preventing the material jacking column 361 from jamming during downward resetting.

[0058] 3. transfer mechanism 20

[0059] As shown in Figure 1 Figure 4 and Figure 5 and Figure 8 The transfer mechanism 20 transfers the cut paperboard b ejected by the ejection mechanism 36, and the transfer mechanism 20 includes a transfer seat 22 driven by a transfer drive assembly 21 and moving horizontally and linearly, and the transfer drive assembly 21 can be a straight stroke power mechanism such as a screw sliding block mechanism, a pneumatic cylinder or a hydraulic cylinder. The transfer seat 22 is fixed with a supporting piece, and when the upper part of the lifting part protrudes above the profile cutter 321, the movement path of the supporting piece is staggered with the upper part of the lifting part and intersects with the position directly below the cut paperboard b ejected. In use, the supporting piece is moved to the position below the cut paperboard b, and then the lifting part slides downward, and the cut paperboard b is supported by the supporting piece instead of the lifting part, and at this time, the transfer seat 22 driven by the transfer drive assembly 21 moves, thereby realizing the transfer of the cut paperboard b.

[0060] Further, as shown in Figure 8 The upper part of the supporting piece is provided with a transfer pressing plate 23 for pressing the cut paperboard b, and the transfer pressing plate 23 is driven by a transfer pressing power assembly 24 on the transfer seat 22 to move up and down, and the transfer pressing power assembly 24 can be a straight stroke power mechanism such as a screw sliding block mechanism, a pneumatic cylinder or a hydraulic cylinder. When the supporting piece supports the cut paperboard b, the top of the cut paperboard b is pressed by the transfer pressing plate 23, which can prevent the cut paperboard b from falling off the supporting piece during the transfer process, and also prevent the cut paperboard b from scattering during the transfer process when the cut paperboard b has a multi-layer structure.

[0061] Further, as shown in Figure 3 and Figure 5 The supporting piece is a supporting plug rod 25 arranged in parallel to the length direction of the horizontal linear reciprocating motion direction of the transfer seat 22, and the supporting plug rod 25 is arranged in parallel and spaced apart at least two, and the rod-shaped structure of the supporting plug rod 25 facilitates the cooperation between the lifting part, and the design of the at least two supporting plug rods 25 can also realize the stable support of the bottom of the cut paperboard b. It is worth mentioning that the structure design of the supporting plug rod 25, combined with the above-mentioned dot matrix distribution of several ejection columns 361 in the vertical visual angle, forms the lifting part, and the supporting plug rod 25 only needs to align the movement path with the row spacing or vertical spacing of the ejection columns 361.

[0062] 4. transfer mechanism 40

[0063] As shown in Figure 8 and Figure 9As shown, the transfer mechanism 40 is used for receiving the cut paperboard b, and the transfer mechanism 40 comprises a transfer table top which is composed of at least three strip faces arranged in parallel and at intervals. In the embodiment in which the support member is at least two support rods 25, the transfer seat 22 moves horizontally and linearly in a direction parallel to the length direction of the strip face, and the at least two support rods 25 are respectively inserted into the intervals between adjacent strip faces. The transfer mechanism 20 further comprises a discharging lifting transmission assembly 26 which can drive the transfer seat 22 to move up and down, and the discharging lifting transmission assembly 26 can be a lead screw and sliding block mechanism, a pneumatic cylinder or a hydraulic cylinder or other direct stroke power mechanism. The transfer table top of the transfer mechanism 40 adopts the form of strip faces arranged at intervals to avoid the support rods 25, and when the cut paperboard b is moved to the position directly above the transfer table top by the support rods 25, the transfer seat 22 is driven by the discharging lifting transmission assembly 26 to move downward, and the cut paperboard b on the support rods 25 is slid to the intervals between the strip faces and stably placed on the strip faces.

[0064] On the basis of the above, Figure 8 and Figure 9 As shown, the transfer mechanism 40 further comprises a mounting frame 42, and the mounting frame 42 is installed with a belt conveying assembly 43 driven by a belt motor 44. The belt conveying assembly 43 is arranged in at least three groups in parallel and at intervals, and the upper surface of the belt of the belt conveying assembly 43 constitutes the strip face. The transfer mechanism 20 is arranged adjacent to the conveying starting end of the belt conveying assembly 43. The upper surface of the belt of the belt conveying assembly 43 constitutes the strip face, so that when the cut paperboard b is placed at the starting end of the belt conveying assembly 43 by the transfer mechanism 20, the cut paperboard b can be conveyed to the end of the belt conveying assembly 43 by rotating the belt conveying assembly 43 by a certain angle, and a plurality of materials can be accumulated on the transfer platform at one time and then stacked, so as to realize the synchronous stacking of a plurality of materials at one time. In addition, a long time is reserved for the stacking operation during the accumulation of a plurality of materials on the transfer platform, so that when the time required for paperboard cutting and transfer is less than the time required for stacking, it is not necessary to wait for the completion of the stacking operation after the cutting and transfer, and the production efficiency of the paperboard processing is effectively improved.

[0065] In addition, as shown in Figure 9 All the transmission wheels on the same side of the belt conveying assemblies 43 are fixed through 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 conveying assembly 43 can be inserted by the support rod 25, so as to ensure the synchronous rotation of all the belt conveying assemblies 43, and to realize the stable transfer of the cut paperboard b.

[0066] Further, as shown in Figures 8-10As shown, a vertically arranged baffle 45 is provided at the conveying end of the belt conveyor assembly 43 to prevent the cut cardboard b from falling off the conveying end of the belt conveyor assembly 43. Since the vertical arrangement of the baffle 45 inevitably creates a gap with the conveying end of the belt conveyor assembly 43, the cut cardboard b may fall through this gap. Therefore, this gap also needs to be addressed. Figure 10 As shown, a horizontal support bar 451 is fixed on the side of the baffle 45 near the belt conveyor assembly 43. 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 supported 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 ensures that the front end of the cut cardboard b can fall stably onto the horizontal support bar 451 after separating 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 excessive friction between the outer surface of the belt of the belt conveyor assembly 43 and the cut cardboard b, which could cause the front end of the cut cardboard b to collide with the baffle 45 and overturn.

[0067] It is worth mentioning that the transfer mechanism 40 may also include a waste bin 41, with a transfer platform arranged directly above the waste bin 41. The waste bin 41 and the feeding platform 11 are respectively arranged at both ends of the cutting table 31. The waste bin 41 has an opening at the top, and the height of the opening at the top of the waste bin 41 is lower than the height of the top surface of the cutting table 31. During the process of the feeding platform 11 continuously supplying new cardboard a to the cutting table 31, the waste material remaining on the cutting table 31 will be pushed forward. When the waste material moves to the opening at the top of the waste bin 41, it will automatically fall into the interior of the waste bin 41, completing the automatic collection of the waste material after cutting, effectively improving the convenience of waste material collection after cutting.

[0068] 5. Palletizing mechanism 50

[0069] like Figures 11-12As shown, the stacking mechanism 50 is used for stacking the cut paper boards b on the transfer table of the transfer mechanism 40. The stacking mechanism 50 comprises a stacking seat 53 and a stacking table 56 distributed immediately 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 to make horizontal reciprocating motion and vertical lifting motion of the stacking seat 53 respectively, the stacking horizontal power assembly 51 and the stacking lifting power assembly 52 can be a straight stroke power mechanism such as a screw block mechanism, a pneumatic cylinder or a hydraulic cylinder, and finally can realize the horizontal reciprocating motion and the lifting motion of the stacking seat 53. A telescopic supporting part which can slide horizontally is arranged on the stacking seat 53, the telescopic supporting part is driven by a telescopic power assembly 55 and can be retracted into the stacking seat 53, and the telescopic power assembly 55 can also be a straight stroke power mechanism such as a screw block mechanism, a pneumatic cylinder or a hydraulic cylinder. The movement path of the telescopic supporting part is staggered with the transfer table in the vertical visual angle, and can be moved to the position immediately below the cut paper board b to lift the cut paper board b and separate it from the transfer table. In work, the telescopic supporting part is moved to the position immediately below the cut paper board b by the stacking horizontal power assembly 51, then the telescopic supporting part is driven upward by the stacking lifting power assembly 52 to separate the cut paper board b from the transfer table. Then the telescopic supporting part and the cut paper board b are moved to the specified area on the stacking table 56 by the stacking horizontal power assembly 51, and the telescopic supporting part and the cut paper board b are lifted to the specified stacking height by the stacking lifting power assembly 52. At this time, the telescopic supporting part is retracted into the stacking seat 53 by the telescopic power assembly 55, so that the cut paper board b loses the support of the telescopic supporting part and falls to the specified position on the stacking table 56, thereby realizing the automatic stacking of the paper board b. In specific implementation, the specified area and the specified stacking height are determined according to the size of the cut paper board b, and the automatic stacking operation is realized by the controller of the existing technology or the controller combined with the sensor. The content of the controller is the existing technology, which will not be described here.

[0070] In the embodiment in which the transfer table is composed of at least three strip-shaped faces arranged in parallel and at intervals, as shown in Figure 11 The horizontal reciprocating motion direction of the stacking seat 53 is parallel to the length direction of the strip-shaped face, and the telescopic supporting part is a telescopic insertion rod 54 which slides and retracts axially, the length direction of the telescopic insertion rod 54 is parallel to the length direction of the strip-shaped face, and the telescopic insertion rod 54 is at least two which can be inserted into the interval between adjacent strip-shaped faces respectively. The transfer table of the transfer mechanism 40 adopts the form of strip-shaped faces distributed at intervals to avoid the telescopic insertion rod 54, without the need to set a larger interval for avoiding the telescopic supporting part, which not only ensures the uniform support of the bottom of the cut paper board b, but also enables the telescopic insertion rod 54 to be set with multiple rods correspondingly, so that the bottom of the cut paper board b can be stably supported when the telescopic insertion rod 54 lifts the cut paper board b.

[0071] AsFigure 11 As shown, the transfer mechanism 40 further comprises a mounting frame 42, on which a belt conveying assembly 43 driven by a belt motor 44 is mounted, and the belt conveying assembly 43 is arranged in at least three groups in parallel and spaced distribution. In the embodiment in which the upper surface of the belt of the belt conveying assembly 43 constitutes a strip surface, the stacking mechanism 50 is arranged adjacent to the conveying end of the belt conveying assembly 43. By adopting the form in which the upper surface of the belt of the belt conveying assembly 43 constitutes a strip surface, when the transfer mechanism 20 places the cut paper b at the starting end of the belt conveying assembly 43, the belt conveying assembly 43 can be rotated by a certain angle, so that the cut paper b can be conveyed to the end of the belt conveying assembly 43, and a plurality of materials can be accumulated on the transfer platform at one time, and then stacked by the stacking mechanism 50, so as to realize the synchronous stacking of a plurality of materials at one time. In addition, during the accumulation of a plurality of materials on the transfer platform, a longer working time is reserved for the stacking mechanism 50, so that when the time required for paper cutting and transfer is less than the time required for the stacking mechanism 50, it is not necessary to wait for the completion of the work of the stacking mechanism 50 after cutting and transfer, thereby effectively improving the production efficiency and continuity of paper processing.

[0072] As shown in the figure, Figure 9 As shown, the same side transmission wheels of all the belt conveying assemblies 43 are fixed through 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 conveying assembly 43 can be inserted by the telescopic inserting rod 54, so as to ensure the synchronous rotation of all the belt conveying assemblies 43, thereby realizing the stable transfer of the cut paper b.

[0073] As shown in the figure, Figure 10 As shown, the table surface of the stacking table 56 is in a rectangular structure, and the long side direction of the rectangle is parallel to the horizontal reciprocating motion direction of the stacking seat 53, so as to realize the multi-linear length stacking along the length direction of the stacking table 56.

[0074] It is worth mentioning that the above-mentioned transfer mechanism 20, transfer mechanism 40 and stacking mechanism 50 can be collectively used as a transfer and stacking device in the cutting device of the paperboard. In actual implementation, the transfer and stacking device can realize the transfer and stacking operation by separately arranging the stacking mechanism 50, and only needs to modify the cut paper b on the transfer mechanism 40 to the paper b on the lifting part of the cutting mechanism 30. Of course, the separate transfer and stacking of the cut paper by the stacking mechanism 50 will cause the overall stacking time to be longer, and the cutting mechanism 30 needs to wait for the stacking operation of the stacking mechanism 50.

[0075] In order to realize efficient and continuous cutting and stacking operation, the optimized cutting and stacking method will be further described below, which comprises the following steps:

[0076] S1, the paperboard on the feeding table 11 is pushed by the pushing side of the pushing and swinging lever 13, and a group of printing patterns on the front side of the paperboard is moved to the cutting area of the cutting table 31 of the cutting mechanism 30;

[0077] S2, the profiled cutter 321 above the cutting table 31 moves downward, the profiled cutter 321 cuts the paperboard along the edge of the printing pattern and forms the cut paperboard b;

[0078] S3, the cut paperboard b is lifted upward by the lifting part of the ejection mechanism 36 below the cut paperboard b, and the cut paperboard b is moved above the profiled cutter 321;

[0079] S4, the cut paperboard b is transported by the transfer and stacking device and is stacked according to the prediction strategy, and the ejection mechanism 36 is reset;

[0080] S5, the pushing and swinging lever 13 pushes the paperboard forward again, and the cut waste is deviated from the cutting area, and at this time, the group of printing patterns on the front side is moved to the cutting area;

[0081] S6, the steps S2-S5 are cycled, and when the table surface behind the pushing and swinging lever 13 on the feeding table 11 generates a placement area sufficient to accommodate the new paperboard a, the new paperboard a is positioned and placed in the placement area of the feeding table 11, and the cycle of steps S2-S5 is stopped when the last group of printing patterns on the paperboard is moved to the cutting area, and a group of steps S2-S4 is continued, and the pushing and swinging lever 13 returns to the step S1 after the pushing and swinging lever 13 is reset and the step S4 is completed.

[0082] In the cutting and stacking method, the feeding mechanism 10 places the new paperboard a in the placement area in advance during the advancing action of the pushing and swinging lever 13 with the servo base 17, and the hinge design of the pushing and swinging lever 13 allows the pushing and swinging lever 13 to avoid the new paperboard a and reset during the return action. The new paperboard a is positioned and installed before the pushing and swinging lever 13 is reset, and the time interval for cutting and transferring and stacking the last group of printing patterns is used to realize the return and reset of the pushing and swinging lever 13, so that the pushing and swinging lever 13 does not need to wait for the return and reset after the cutting is completed, thereby avoiding the interruption of the continuous cutting operation of the paperboard, and further ensuring the processing efficiency of the paperboard.

[0083] On the basis of the above, the prediction strategy in step S4 of the cutting and stacking method is that the transfer mechanism 20 transfers the cut paper b to the transfer mechanism 40, and after the transfer mechanism 40 accumulates enough cut paper b, the stacking mechanism 50 stacks the cut paper b accumulated on the transfer mechanism 40 on the stacking table 56. The form of the cut paper b accumulated on the transfer mechanism 40 by the transfer mechanism 20 enables the transfer mechanism 50 to transfer multiple groups of materials in one operation; at the same time, the cut paper b is accumulated on the transfer mechanism 40 for a long time to reserve operation time for the stacking mechanism 50, so that when the time required for paper cutting and transfer is less than the time required for the stacking mechanism 50, it is not necessary to wait for the operation of the stacking mechanism 50 to be completed after cutting and transfer, effectively improving the production efficiency and continuity of paper processing.
