Description

Technical Field

[0001] The utility model relates to a positive pressure feeding structure for paper cutting and a cutting machine, belonging to the technical field of cutting machines. Background Art

[0002] In the process of producing and using paper, workers usually use a cutting machine to cut the paper to obtain paper of different sizes required by people.

[0003] In the actual use of the cutting machine, since the cutting machine needs to cut a large amount of paper, when the cutting machine finishes cutting, the staff needs to move the paper stack away from the working table of the cutting machine so as to cut the next stack of paper. This moving process is time-consuming and labor-intensive. In order to improve the unloading efficiency, in the prior art, people often set an unloading device at one end of the cutting machine.

[0004] However, in the actual use of the unloading device, there are still some disadvantages: when the unloading device unloads the cut multiple paper stacks on the pallet and in the process of pulling out the paper stacks, one end of the first paper stack will abut against the surface of the pallet under the downward force of the hydraulic cylinder, and the remaining paper stacks have a height difference with the surface of the pallet due to the thickness of the unloading device. When the unloading device is pulled outward, under the influence of the height difference, the paper on the top of the paper stack will become crooked and scattered. In the subsequent process of packaging the paper stacks, manual sorting and alignment are required, which brings great trouble to the staff, is time-consuming and labor-intensive, and is very inconvenient. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a positive pressure feeding structure and a cutting machine for paper cutting, which solves the problem in the prior art that when the feeding device is pulled outward, the paper at the top of the paper stack will be skewed and scattered due to the influence of the height difference, and in the subsequent process of packaging the paper stack, it is necessary to manually sort and align it, which brings great trouble to the staff, is time-consuming and labor-intensive, and is very inconvenient.

[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a positive pressure feeding structure for paper cutting, comprising a feeding mechanism and a tray placed on the ground, the feeding mechanism comprising a feeding plate, a plurality of fork blocks for lifting paper stacks are integrally formed on the feeding plate, a plurality of fork grooves for inserting the fork blocks are provided on the tray, the depth of the fork grooves is not less than the thickness of the fork blocks, and the feeding mechanism also comprises a driving mechanism for driving the feeding plate to move.

[0007] By adopting the above technical solution, in the actual use of the positive pressure feeding structure, the fork block is completely inserted into the fork groove, so that several piles of paper can be placed flatly and smoothly on the surface of the pallet, and the paper on the top of the paper pile will not be skewed and scattered. In the subsequent process of packaging paper, the staff does not need to sort and align the paper piles, saving time and effort.

[0009] By adopting the above technical solution, the sliding rod slides on the guide rail and the connecting rod slides on the sliding rod, so that the blanking plate can move in the horizontal and vertical directions, thereby realizing the driving effect of the driving mechanism on the blanking plate, and the movement of the sliding rod and the connecting rod is controlled by the CNC program and the hydraulic cylinder, so that the movement of the blanking plate is more stable and the degree of automation is higher.

[0010] The utility model is further configured as follows: baffles are provided on both sides of the tray, the baffles are slidably connected to the top of the tray in a vertical direction, adjusting parts for adjusting the height of the baffles are provided on both sides of the tray, plate grooves are provided on both sides of the tray, the adjusting parts include a rotating shaft rotatably connected to the plate groove, a gear is fixed on the rotating shaft, a rack meshing with the gear slides in the plate groove in a vertical direction and one end of the rack is connected to the baffle, a cover plate is also clamped on the outer side of the plate groove, one end of the rotating shaft extends out of the cover plate and is provided with a limiting structure for cooperating with the cover plate to limit the rotation of the rotating shaft, the limiting structure includes a clamping cap slidably connected to the outer side of the rotating shaft in an axial direction, the clamping cap is polygonal, a protrusion is provided on the inner circumferential wall of the clamping cap, and a groove for the protrusion to be clamped in is provided on the outer circumferential wall of the rotating shaft in an axial direction.

[0011] By adopting the above technical solution, the setting of the baffle can effectively prevent the paper stack from sliding sideways and scattering when the paper stack is stacked on the pallet, and the setting of the adjustment member can make the baffle adapt to and block paper stacks of different heights by adjusting the height of the baffle, so that the transportation of the paper stack is more stable when the staff lifts the pallet with a forklift.

[0012] When adjusting the height of the baffle, the staff only needs to turn the clamping cap, thereby realizing the operation of adjusting the height of the baffle by the adjusting member, and the operation is convenient.

[0013] The setting of the cover plate limits the position of the rack and the gear through the cover plate, so that the rack and the gear cannot be separated from the plate groove, and the connection is more stable.

[0014] The utility model is further configured as follows: the cover plate is provided with a card slot for the card cap to be carded in.

[0015] By adopting the above technical solution, when the height of the baffle needs to be fixed, the only work is to push the card cap in the direction toward the cover plate so that the card cap can be inserted into the card slot, which can prevent the gear, rack and baffle from moving, thereby completing the baffle height fixing operation, which is easy to operate.

[0016] The utility model is further configured as follows: a positioning plate for abutting against the fork block is arranged on the guide rail.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0026] like Figure 1 As shown, a positive pressure feeding structure for paper cutting includes a feeding mechanism and a tray 7 placed on the ground. The feeding mechanism includes a feeding plate 4, on which a plurality of fork blocks 5 for lifting a paper stack are integrally formed. The tray 7 is provided with a plurality of fork grooves 6 for inserting the fork blocks 5. The depth of the fork grooves 6 is not less than the thickness of the fork blocks 5. The feeding mechanism also includes a driving mechanism for driving the feeding plate 4 to move.

[0027] In the actual use of the positive pressure unloading structure, the staff can first drive the unloading plate 4 and the fork block 5 to lift several piles of paper through the driving mechanism, and then move the fork block 5 to the top of the tray 7 and align it with the fork groove 6. Finally, it only needs to move the fork block 5 downward in the vertical direction so that the fork block 5 is completely stuck in the fork groove 6. Then, several piles of paper can be placed flat and smoothly on the surface of the tray 7, and the paper on the top of the paper pile will not be skewed and scattered. In the subsequent process of packaging the paper, the staff can save the steps of arranging and aligning the paper piles, saving time and effort.

[0028] like Figure 2 As shown, the driving mechanism includes a fixed guide rail 1, the guide rail 1 is slidably connected to a slide rod 2 along the length direction, the slide rod 2 is slidably connected to a connecting rod 3 along the vertical direction, and a blanking plate 4 is arranged on the connecting rod 3. In this embodiment, the sliding of the slide rod 2 and the connecting rod 3 are controlled by a CNC program and a hydraulic cylinder (not shown in the figure).

[0029] By sliding the slide bar 2 on the guide rail 1 and the connecting rod 3 on the slide bar 2, the blanking plate 4 can be moved in the horizontal and vertical directions, thereby realizing the driving effect of the driving mechanism on the blanking plate 4, and the movement of the slide bar 2 and the connecting rod 3 is controlled by the CNC program and the hydraulic cylinder (not marked in the figure), so that the movement of the blanking plate 4 is more stable and the degree of automation is higher.

[0030] like Figure 3 and Figure 4 As shown, baffles 8 are provided on both sides of the tray 7, and the baffles 8 are slidably connected to the top of the tray 7 in the vertical direction. Adjusting members for adjusting the height of the baffles 8 are provided on both sides of the tray 7. Plate grooves 16 are provided on both sides of the tray 7. The adjusting members include a rotating shaft 12 rotatably connected to the plate groove 16, and a gear 17 is fixed on the rotating shaft 12. A rack 15 meshing with the gear 17 slides in the plate groove 16 in the vertical direction, and one end of the rack 15 is connected to the baffle 8. A cover plate 10 is also clamped on the outer side of the plate groove 16, one end of the rotating shaft 12 extends out of the cover plate 10 and is provided with a limiting structure for cooperating with the cover plate 10 to limit the rotation of the rotating shaft 12, and the limiting structure includes a clamping cap 11 slidably connected to the outer side of the rotating shaft 12 along the axial direction, the clamping cap 11 is polygonal, and a protrusion 14 is provided on the inner circumferential wall of the clamping cap 11, and a groove 13 for the protrusion 14 to be clamped is provided on the outer circumferential wall of the rotating shaft 12 along the axial direction.

[0031] The setting of the baffle 8 can effectively prevent the paper stack from sliding sideways and scattering when the paper stack is stacked on the tray 7, and the setting of the adjusting member can make the baffle 8 adapt to and block paper stacks of different heights by adjusting the height of the baffle 8, so that the transportation of the paper stack is more stable when the staff lifts the tray 7 by forklift.

[0032] Among them, when adjusting the height of the baffle 8, the staff only needs to rotate the cap 11, and the groove 13 limits the protrusion 14, so that the rotation of the cap 11 can drive the rotating shaft 12 to rotate, thereby driving the gear 17 to rotate, and then the rack 15 and the baffle 8 can slide in the vertical direction, thereby realizing the operation of adjusting the height of the baffle 8 by the adjusting part, and the operation is convenient.

[0033] The arrangement of the cover plate 10 limits the rack 15 and the gear 17 so that the rack 15 and the gear 17 cannot be separated from the plate groove 16, and the connection is more stable.

[0034] like Figure 4 As shown, the cover plate 10 is provided with a slot 18 for the cap 11 to be inserted into.

[0035] When the height of the baffle 8 needs to be fixed, the work only needs to push the cap 11 in the direction toward the cover plate 10 so that the cap 11 can be inserted into the slot 18. The slot 18 limits the cap 11 so that the cap 11 cannot rotate. The protrusion 14 limits the rotating shaft 12 so that it cannot rotate, thereby preventing the gear 17, the rack 15 and the baffle 8 from moving, thereby completing the height fixing operation of the baffle 8, which is easy to operate.

[0036] like Figure 2 As shown, a positioning plate 9 for abutting against the fork block 5 is provided on the guide rail 1 .

[0037] The setting of the positioning plate 9 allows the fork block 5 to only abut against the positioning plate 9 when it needs to be aligned with the fork groove 6. Under the positioning effect of the positioning plate 9, the fork block 5 can be accurately aligned with the fork groove 6, thereby facilitating the insertion of the fork block 5.

[0038] The embodiment of the utility model further provides a cutting machine using the positive pressure blanking structure, including the positive pressure blanking structure as described above. It should be noted that the guide rail 1 is fixedly arranged at the blanking end of the cutting machine.

[0039] Since the cutting machine adopts all the technical solutions of the positive pressure blanking structure of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0040] Working principle:

[0041] In the actual use of the positive pressure unloading structure, the staff can first drive the unloading plate 4 and the fork block 5 to lift a number of paper piles through the CNC program and the hydraulic cylinder (not shown in the figure), and then slide the slide bar 2 on the guide rail 1 to move the fork block 5 to the top of the pallet 7 and align it with the fork groove 6. The setting of the positioning plate 9 makes it possible for the fork block 5 to be accurately aligned with the fork groove 6 by only abutting the positioning plate 9 when the fork block 5 needs to be aligned with the fork groove 6, thereby facilitating the insertion of the fork block 5, and then move the fork block 5 downward in the vertical direction on the slide bar 2 through the connecting rod 3 so that the fork block 5 is completely inserted into the fork groove 6, and the several paper piles can be placed flatly and smoothly on the surface of the pallet 7.

[0042] Then, when the staff adjusts the height of the baffle 8 according to the height of the paper stack, they only need to rotate the cap 11. The groove 13 limits the protrusion 14, so that the rotation of the cap 11 can drive the shaft 12 to rotate, thereby driving the gear 17 to rotate, and then the rack 15 and the baffle 8 can slide in the vertical direction. When the height of the baffle 8 is not less than the height of the paper stack, the baffle 8 can effectively prevent the paper stack from sliding sideways and scattering. Then the staff only needs to push the cap 11 in the direction toward the cover plate 10 so that the cap 11 can be inserted into the slot 18. The slot 18 limits the cap 11, so that the cap 11 cannot rotate, and the protrusion 14 limits the shaft 12, so that it cannot rotate, so that the gear 17, the rack 15 and the baffle 8 cannot move, thereby completing the height fixing operation of the baffle 8, and the operation is convenient.

[0043] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments.
