In addition, due to the limited width of the cutting platform, if the paperboard output by the feeding mechanism is located exactly in the middle of the cutting platform, the effective utilization area of ​​the cutting platform will be reduced, thereby reducing the corresponding work efficiency.

DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0028] like Figures 1 to 9 As shown, the present invention provides a feeding mechanism, comprising: A feeding frame 100 is provided with a material conveying channel, and the two ends of the conveying channel are respectively a feeding end 110 and a discharging end 120, wherein the feeding end 110 is used to store the stacked materials, and the discharging end 120 is used to communicate with the cutting area in the cutting device; The buffer assembly 200 is located on the conveying channel. The buffer assembly 200 includes a buffer bracket 210 installed on the feeding frame 100, and a conveying structure 220 is arranged on the buffer bracket 210. The conveying structure 220 includes an active roller 221 and a driven roller 222 located at both ends of the buffer bracket 210 along the material conveying direction. The active roller 221 and the driven roller 222 are connected by an annular conveyor belt 223. The active roller 221 is located at the discharge end 120, and one end of the active roller 221 in the axial direction is connected to a conveying motor 224. The upper pressure roller assembly 300 is located above the active roller 221. The upper pressure roller assembly 300 includes a pressure roller bracket 310 installed on the feed frame 100, and a pressure roller lifting cylinder 320 is arranged on the pressure roller bracket 310, and the output end of the pressure roller lifting cylinder 320 is connected to a pressure roller structure 330, wherein the pressure roller structure 330 includes an upper pressure roller shaft 331, a plurality of rollers 332 are arranged along the axial direction of the upper pressure roller shaft 331, and a pressure roller motor 333 that drives the upper pressure roller shaft 331 to rotate, and the relative distance between the roller 332 and the circular conveyor belt 223 is changed by the pressure roller lifting cylinder 320.

[0029] It is worth mentioning that when the material is located on the buffer bracket 210, the material is moved toward the discharge end 120 through the circular conveyor belt 223. At this time, the entire pressure roller structure 330 is driven by the pressure roller lifting cylinder 320 to move toward the buffer bracket 210. When one end of the material moves to the discharge end 120, the material is clamped between the roller 332 and the circular conveyor belt 223. Since the contact between the material and the roller 332 is line contact, the contact area between the material and the roller 332 is reduced, thereby avoiding the phenomenon of material slipping during transportation, thereby improving the material transportation effect and the subsequent material cutting accuracy.

[0030] It is further pointed out that the active roller 221 and the driven roller 222 are connected by a plurality of annular conveyor belts 223, and there is a gap between two adjacent annular conveyor belts 223, wherein the plurality of rollers 332 correspond one to one with the plurality of annular conveyor belts 223, and the pressure roller lifting cylinder 320 enables the plurality of rollers 332 to contact or separate with the plurality of annular conveyor belts 223 synchronously.

[0031] In this embodiment, multiple rollers 332 and multiple annular conveyor belts 223 are provided, so that when the material is conveyed to the discharge end 120, it can be clamped by the multiple rollers 332 and the corresponding annular conveyor belts 223, thereby further avoiding slipping. In addition, the multiple rollers 332 and the multiple annular conveyor belts 223 correspond one-to-one to avoid deformation of the material due to the clamping force generated when the rollers 332 and the annular conveyor belts 223 abut against each other, thereby ensuring that the material remains flat after passing through the rollers 332 and the annular conveyor belts 223, thereby improving the accuracy of subsequent cutting.

[0032] It is further pointed out that the rotation speed of the roller 332 is synchronously set with the rotation speed of the endless conveyor belt 223, that is, there is no corresponding speed difference between the two, so as to avoid relative sliding between the two.

[0033] Preferably, the cache bracket 210 includes a cache platform 211, and a transverse profile 212 is respectively arranged on both sides of the cache platform 211, and the length direction of the two transverse profiles 212 is consistent with the conveying direction of the material, wherein the two sides of the cache platform 211 are respectively connected to the transverse profiles 212 on the corresponding side through a cache support plate 213, and the cache support plate 213 is arranged in an L shape, and the two ends of the driven roller 222 are respectively connected to one end of the two transverse profiles 212 through a first roller connector 214; the first longitudinal profile 215 is arranged on the same side as the active roller 221, and is distributed up and down with the active roller 221, and the two ends of the first longitudinal profile 215 are respectively connected to the two ends of the active roller 221 through a second roller connector 216, wherein the other ends of the two transverse profiles 212 are connected to the second roller connector 216.

[0034] It is worth mentioning that the cache platform 211 is interspersed in the multiple circular conveyor belts 223 between the active roller 221 and the driven roller 222 . In other words, the upper surface and the lower surface of the cache platform 211 are located between the upper and lower sides of the circular conveyor belt 223 .

[0035] Further preferably, a tensioning structure 230 is included below the active roller 221, and the tensioning structure 230 includes a tensioning shaft 231, and both ends of the tensioning shaft 231 are connected to the first longitudinal profile 215 through tensioning brackets 232, wherein an even number of struts 233 are nested on the tensioning shaft 231 along the axial direction of the tensioning shaft 231, and a tensioning wheel 234 is connected between two adjacent struts 233, and the tensioning wheel 234 fits the endless conveyor belt 223. The tensioning force of the endless conveyor belt 223 is ensured by the tensioning wheel 234.

[0036] Preferably, the pressure roller support 310 includes: The second longitudinal profile 311, both ends of which are mounted on the feeder frame 100 through profile support plates 312; Two profile fixing seats 313 are arranged in an L shape and are respectively located at the two ends of the second longitudinal profile 311, and one side of the profile fixing seat 313 is connected to the second longitudinal profile 311, and the other side of the profile fixing seat 313 is connected to two guide rod seats 314 distributed up and down, wherein the pressure roller lifting cylinder 320 is connected to the guide rod seat 314 located on the upper side through the cylinder support plate 315, and the two guide rod seats 314 are connected through the guide rod 316; The guide sleeve 317 is nested on the guide rod 316, and is connected to a guide vertical plate 318 on the guide sleeve 317, and a pressure roller support plate 319 is connected to the guide vertical plate 318, wherein the lifting direction of the guide vertical plate 318 is perpendicular to the length direction of the pressure roller support plate 319, and the output end of the pressure roller lifting cylinder 320 is connected to the pressure roller support plate 319, and the pressure roller structure 330 is connected to the pressure roller support plate 319.

[0037] It is worth mentioning that the output end of the pressure roller motor 333 is parallel to the axial direction of the upper pressure roller shaft 331, and is arranged up and down, wherein the pressure roller motor 333 is connected to the pressure roller support plate 319 through a motor mounting seat, and the output end of the pressure roller motor 333 is connected to the upper pressure roller shaft 331 through a pulley structure, and the two ends of the upper pressure roller shaft 331 are respectively rotatably connected to the guide vertical plate 318.

[0038] In this embodiment, the pressure roller lifting cylinder 320 drives the pressure roller support plate 319, the guide vertical plate 318, and the guide sleeve 317 to move up and down along the axial direction of the guide rod 316. Since the pressure roller motor 333 is connected to the pressure roller support plate 319 through the motor mounting seat, and the two ends of the upper pressure roller shaft 331 are connected to the guide vertical plate 318, the entire pressure roller structure 330 can move up and down following the extension and retraction of the output end of the pressure roller lifting cylinder 320, thereby realizing the roller 332 approaching or moving away from the annular conveyor belt 223.

[0039] It is further pointed out that a hydraulic buffer 340 is also connected to the guide rod seat 314 on the lower side, and the output end of the hydraulic buffer 340 corresponds to the end face of the guide sleeve 317, so that the guide sleeve 317 will hit the output end of the hydraulic buffer 340 during the descent process. In this way, the impact of the roller 332 on the annular conveyor belt 223 when the pressure roller structure 330 is descending can be reduced, thereby avoiding damage to the material.

[0040] Preferably, a front positioning assembly 400 is further provided at the feed end 110 , and the front positioning assembly 400 is connected to the first longitudinal profile 215 , wherein the front positioning assembly 400 ensures that the front edge of the material remains flat when passing through the discharge end 120 .

[0041] Further preferably, the front positioning assembly 400 includes: A plurality of transition brackets 410, wherein the plurality of transition brackets 410 are installed on the first longitudinal profile 215; A plurality of front positioning cylinders 420 are respectively installed at one end of the transition bracket 410, and the output end of each front positioning cylinder 420 is connected to a connecting plate 430, wherein a material blocking rod 440 is installed at both ends of each connecting plate 430; The feeding transition plate 450 is connected to the other end of the transition bracket 410 , and a through hole 451 for the material blocking rod 440 to pass through is provided on the feeding transition plate 450 .

[0042] In this embodiment, the front positioning cylinder 420 is used to extend the material blocking rod 440 through the connecting plate 430. When the front end edge of the material contacts the material blocking rod 440, the front end edge of the material is regulated to ensure that the conveying direction of the material is perpendicular to the front end edge of the material, and the material enters the cutting area in a straight line rather than tilted horizontally, thereby improving the subsequent cutting accuracy of the material.

[0043] It is worth mentioning that in a feeding mechanism and a cutting device mentioned in the background technology, a front positioning component 400 is also provided, but the front positioning component 400 adopts a material blocking plate, and the lifting and lowering of the material blocking plate requires a gap to be set on the feeding transition plate 450, and the material is a flexible material. The gap with a longer width will cause the material with a smaller width to directly enter the gap when it is conveyed to the feeding transition plate 450, and the material blocking effect cannot be achieved. In this embodiment, a material blocking rod 440 is provided, and it is only necessary to open a through hole 451 on the feeding transition plate 450 for the lifting and lowering of the material blocking rod 440, and the width of the material must be much larger than the aperture of the through hole 451, so the material will not be inserted into the through hole 451, thereby improving the material blocking effect.

[0044] Preferably, a side positioning assembly 500 is also provided on the feeding channel, and the side positioning assembly 500 is located below the buffer platform 211, wherein the side positioning of the material is achieved by the side positioning assembly 500 to ensure the flatness of the side edge line of the material.

[0045] In this embodiment, the front positioning assembly 400 and the side positioning assembly 500 constrain the edge lines of two adjacent sides of the material on the conveying channel, so that the material can enter the cutting area in an orderly manner.

[0046] Further preferably, the side positioning assembly 500 comprises: The third longitudinal profile 510 is installed on the feeding frame 100, and two side positioning cylinders 520 are installed at both ends of the third longitudinal profile 510, wherein the output end of the side positioning cylinder 520 is connected to a side push support seat 530, and the side push support seat 530 is arranged in a C shape; A side thrust motor 540 is mounted on the closed end of the side thrust support seat 530; There are multiple paper feed wheel optical shafts 550, and both ends of each paper feed wheel optical shaft 550 are respectively connected to the two sides of the opening end of the side push support seat 530, and multiple paper feed wheels 560 are arranged on the paper feed wheel optical shaft 550 along the axial direction, wherein two adjacent paper feed wheel optical shafts 550 are connected by a pulley structure, and one of the multiple paper feed wheel optical shafts 550 is connected to the output end of the side push motor 540 by a pulley structure.

[0047] It is worth mentioning that a plurality of recessed holes 2111 are provided on the buffer platform 211, and the position of each recessed hole 2111 corresponds to the position of the paper feed wheel 560, wherein the position of each column of recessed holes 2111 in the material conveying direction is spaced apart from the position of each annular conveyor belt 223, and a raised side baffle 2112 is provided on each side of the buffer platform 211. When the material is located on the buffer platform 211, the side positioning cylinder 520 drives the side push support seat 530 to move upward, so that the highest point of the paper feed wheel 560 passes through the recessed hole 2111 and contacts the material, and then the side push motor 540 drives the multiple paper feed wheel optical axes 550 to rotate synchronously, prompting the multiple paper feed wheels 560 to rotate synchronously, moving the material horizontally laterally, and abutting against the side baffle 2112, thereby realizing lateral positioning of the material.

[0048] Preferably, a material dividing assembly 600 is further provided between the feed end 110 and the buffer assembly 200 , and the stacked materials in the feed end 110 are transported one by one to the buffer platform 211 through the material dividing assembly 600 .

[0049] Further preferably, the material distribution assembly 600 includes: The material distribution bracket 610 spans across both sides of the conveying channel and is connected to the feeding frame 100, and a rack 620 and a sliding structure 630 are respectively connected to the two ends of the material distribution bracket 610 perpendicular to the material conveying channel, wherein the sliding structure 630 and the rack 620 are distributed up and down, and a fixing plate 640 is installed on the opposite side of the two sliding structures 630; The material distribution motor 650 is installed on one of the fixed plates 640, and the output end of the material distribution motor 650 is connected to a connecting shaft 660 that is rotatably connected to the two fixed plates 640, and gears 670 combined with the rack 620 are respectively sleeved on both ends of the connecting shaft 660; The fourth longitudinal profile 680 is connected to two fixed plates 640 at both ends respectively, and a material dividing lifting cylinder 690 is connected to the fourth longitudinal profile 680, and a fifth longitudinal profile 6100 is connected to the output end of the material dividing lifting cylinder 690, wherein a plurality of pressure wheel structures 6200 and suction cup structures 6300 are arranged on the fifth longitudinal profile 6100, and there is a height difference between the lowermost end of the pressure wheel structure 6200 and the lowermost end of the suction cup structure 6300.

[0050] In this embodiment, the pressure wheel structure 6200 and the suction cup structure 6300 are moved to the top of the stacked materials by the material dividing motor 650, and then the pressure wheel structure 6200 and the suction cup structure 6300 are driven to move downward synchronously by the material dividing lifting cylinder 690. At this time, the suction cup structure 6300 first contacts the top layer of the stacked materials, and then sucks the top layer of the materials, and moves upward under the action of the material dividing lifting cylinder 690. At this time, the pressure wheel structure 6200 is not in contact with the material. When the material is placed on the buffer platform 211, the suction cup structure 6300 is released, and the pressure wheel structure 6200 presses down to press the material on the buffer platform 211, and then the annular conveyor belt 223 drives the material to move toward the output end.

[0051] Further preferably, the pressure wheel structure 6200 and the suction cup structure 6300 are on the same straight line, and the pressure wheel structure 6200 and the suction cup structure 6300 are spaced apart from each other.
