Description

Technical Field

[0001] The utility model belongs to the technical field of carton processing, in particular to an adjustable slotting machine for carton processing. Background Art

[0002] Cardboard boxes are the most widely used packaging products. They come in a variety of sizes and models, depending on the material used. Three- and five-layer cartons are common, while seven-layer cartons are less common. Each layer consists of lining paper, corrugated paper, and core paper. Each paper type has different colors and textures, and the colors and textures of paper produced by different manufacturers also vary. Slotting a carton involves cutting the fold lines for the upper and lower flaps into a single piece of cardboard. This process occurs after printing and simultaneously with creasing.

[0003] At present, most of the slotting machines for carton processing on the market can only process and slot a single type of carton. The slotting adaptability for cartons other than this model is low. In addition, when slotting cardboards of different thicknesses, the slotting height accuracy is not high and it is difficult to adjust. Therefore, it is necessary to propose an adjustable slotting machine for carton processing to solve the above problems.

[0004] The Chinese patent with the authorization announcement number CN219789430U discloses an adjustable slotting machine for carton processing, which includes an operating table, a cylinder, a lifting platform, a motor and a cutting roller. The operating table is arranged at the bottom of the device, and cylinders are arranged on both sides of the operating table. The output end of the cylinder is fixedly connected to the lifting platform, and the upper surface of the lifting platform on one side of the operating table is fixedly mounted with a motor. The utility model has a threaded groove and a slide groove on the surface of the cutting roller, which cooperates with the limit plate, the fixed ring and the slider inside the cutting blade to enable the cutting blade to slide on the surface of the cutting roller to adjust the spacing between the cutting blades. It can realize slotting operations on various types of cartons. The structure is simple, convenient and practical. Further, through the cooperation between the cylinder and the lifting platform, it can realize slotting operations on cartons of different thicknesses, thereby improving the efficiency of carton slotting processing.

[0005] However, the above has the following shortcomings:

[0006] The above patent can only adjust the position of the slotting tool to adapt to different slotting positions, but the above patent cannot adjust the slotting width, so it is difficult to adapt to different slotting width requirements and has a small scope of application.

[0007] The cutting groove position of the above-mentioned patent is fixed, which will inversely limit the tool position to be adjustable only at a specified position, resulting in the inability to flexibly adjust the groove position, further limiting the scope of application. Utility Model Content

[0008] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present utility model is to set a first cutting knife and a second cutting knife with coincident tips, and by adjusting the distance between the first round plate and the second round plate, the grooving width can be adjusted, so as to improve the application range of the grooving machine and meet different grooving width requirements. By setting a plurality of closely arranged support blocks, the support position of the cardboard and the positions for avoiding the first cutting knife and the second cutting knife can be freely adjusted according to the grooving position, so that the grooving position can be adjusted more freely, further improving the application range of the grooving machine.

[0009] In order to achieve the above object, the present utility model provides the following technical solution: An adjustable grooving machine for carton processing, comprising a main shaft, a shaft seat and an electric drive cylinder. A plurality of first round plates are slidably connected in a uniform distribution on the outer side of the main shaft. A plurality of second round plates are slidably connected at positions opposite to each first round plate on the outer side of the main shaft. A plurality of first cutting knives are fixedly connected in a uniform distribution on the periphery of each first round plate. A plurality of second cutting knives are fixedly connected in a uniform distribution on the periphery of each second round plate. Each first cutting knife is in close contact with and relatively slides with the corresponding second cutting knife, and the tips of each first cutting knife and the corresponding second cutting knife coincide.

[0010] Further, a set of first limiting protrusions are uniformly arranged on one side of each first round plate facing the second round plate. A set of second limiting protrusions are uniformly arranged on one side of each second round plate facing the first round plate. Each set of first limiting protrusions and the corresponding second limiting protrusions are mutually staggered, closely fitted and relatively slide. An adjusting bolt is rotatably connected at the position corresponding to each first limiting protrusion on each second round plate, and each adjusting bolt is threadedly connected with the corresponding first limiting protrusion.

[0011] Further, a plurality of sliding grooves are formed on the surface of the main shaft. Limiting blocks are fixedly connected at positions corresponding to each sliding groove on the outer sides of each first round plate and each second round plate. Each limiting block is slidably connected with the corresponding sliding groove. A fastening bolt is threadedly connected in each limiting block, and the end of each fastening bolt can contact the surface of the sliding groove.

[0012] Further, two shaft seats are symmetrically and rotatably connected at both ends of the main shaft. An electric drive cylinder is drivingly connected to the bottom of each shaft seat. A motor is fixedly connected to one of the shaft seats, and the power output end of the motor is drivingly connected to one end of the main shaft extending out of the shaft seat.

[0013] Further, a workbench is fixedly connected between the two electric drive cylinders. A plurality of support blocks are slidably connected in a uniform distribution in the workbench, and adjacent support blocks are in close contact with and relatively slide with each other.

[0014] Further, a push rod is slidably connected to the bottom of each support block on one side of the workbench. A set of connecting blocks is fixedly connected to the bottom of each support block. One end of each set of connecting blocks is rotatably connected to a set of connecting rods, and the end of each set of connecting rods away from the connecting block is rotatably connected to the corresponding push rod.

[0015] In summary, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] By setting the first cutting knife and the second cutting knife to be separable and combinable, the grooving width can be changed flexibly, thereby greatly increasing the scope of application.

[0017] By setting the workbench and the support blocks with adjustable support and avoidance positions, the support and avoidance positions can be flexibly adjusted, avoiding restricting the working positions of the first cutting knife and the second cutting knife, and thus realizing flexible setting of the grooving position and improving the scope of application.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Embodiment 1:

[0026] AsFigure 1 As shown, an adjustable slotting machine for carton processing includes a workbench 24, two electric drive cylinders 14 are symmetrically distributed and fixedly connected at both ends of the workbench 24, the extended ends of the two electric drive cylinders 14 are respectively fixedly connected to two mutually symmetrical shaft seats 12, a main shaft 11 is rotatably connected between the two shaft seats 12, a motor 13 is fixedly connected to one of the shaft seats 12, and a power output end of the motor 13 is transmission-connected to one end of the main shaft 11 extending out of the shaft seat 12.

[0027] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a plurality of first wheel plates 16 are evenly distributed and slidably connected on the outer surface of the main shaft 11, and a second wheel plate 17 is slidably connected at the relative position of each first wheel plate 16 on the outer surface of the main shaft 11. A group of first limiting protrusions 23 and second limiting protrusions 29 are respectively provided on both sides close to each other of each first wheel plate 16 and its relative second wheel plate 17. The relative first limiting protrusions 23 and second limiting protrusions 29 are staggered and tightly fit with each other and slide relatively. A plurality of first cutters 18 are evenly distributed and fixedly connected at the periphery of each first wheel plate 16 in the circumferential direction, and a plurality of second cutters 19 are evenly distributed and fixedly connected at the periphery of the second wheel plate 17 in the circumferential direction. Each second cutter 19 is tightly fitted with the corresponding first cutter 18 and slides relatively, and the tip of each second cutter 19 coincides with the tip of the corresponding first cutter 18.

[0028] By setting the first cutter 18 and the second cutter 19 with overlapping tips and adjusting the distance between the first wheel plate 16 and the second wheel plate 17, the slotting width can be adjusted, thereby improving the applicability of the slotting machine and adapting to different slotting width requirements.

[0029] By setting the first limiting protrusion 23 and the second limiting protrusion 29, the first wheel plate 16 and the second wheel plate 17 can be limited to avoid axial deflection between the first wheel plate 16 and the second wheel plate 17, thereby ensuring that the tips of the first cutter 18 and the second cutter 19 always coincide with each other, thereby ensuring the grooving effect.

[0030] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, a regulating bolt 22 is rotatably connected to each second-round plate 17 at a position corresponding to each first limit bump 23, and each regulating bolt 22 is in threaded connection with the corresponding first limit bump 23. A plurality of chutes 15 are evenly distributed on the outer side of the main shaft 11. A limit block 20 is fixedly connected to the outer sides of each first-round plate 16 and second-round plate 17 at positions corresponding to each chute 15. Each limit block 20 extends into the corresponding chute 15 and is slidably connected to the chute 15. A fastening bolt 21 is in threaded connection with each limit block 20, and each fastening bolt 21 contacts the surface of the chute 15.

[0031] By providing the regulating bolt 22, it is convenient for the operator to accurately adjust the distance between the first-round plate 16 and the second-round plate 17, thereby ensuring the accuracy of the grooving width. And by providing the limit block 20, it is convenient for the main shaft 11 to drive the first-round plate 16 and the second-round plate 17 to rotate. The fastening bolt 21 can lock the positions of the first-round plate 16 and the second-round plate 17, thereby preventing the first-round plate 16 or the second-round plate 17 from axially shifting during the processing, and ensuring the accuracy of grooving and the stability of processing.

[0032] As Figure 1 and Figure 6 shown, a plurality of support blocks 25 are slidably connected in the workbench 24 in a uniformly distributed manner. The top of each support block 25 is flush with the top surface of the workbench 24. The adjacent support blocks 25 are in close contact and slide relative to each other. A push rod 26 is slidably connected to the workbench 24 at the bottom of each support block 25. Two connecting blocks 27 are fixedly connected to the bottom of each support block 25. A connecting rod 28 is rotatably connected to each connecting block 27. One end of each connecting rod 28 away from the connecting block 27 is rotatably connected to the corresponding push rod 26.

[0033] By providing a plurality of closely arranged support blocks 25, the support position of the cardboard and the position for avoiding the first cutter 18 and the second cutter 19 can be freely adjusted according to the grooving position, so that the grooving position can be adjusted more freely, further improving the application range of the present grooving machine.

[0034] In this embodiment, initially, the operator connects the device to the power supply and the control system. Before use, according to the actual processing requirements, first loosen each fastening bolt 21 so that each first-round plate 16 and second-round plate 17 can freely slide on the main shaft 11 to adjust the grooving position.

[0035] After adjusting the first round plate 16 and the second round plate 17 to their corresponding positions, the operator first tightens the corresponding fastening bolts 21 on each first round plate 16 to fix the position of each first round plate 16. Then, according to the actual width requirement of the slotting, the operator screws the adjusting bolt 22 to make the first limiting protrusion 23 slide relative to the second limiting protrusion 29, so that the distance between the first round plate 16 and the second round plate 17 increases or decreases. Then, the first cutting knife 18 and the second cutting knife 19 slide relative to each other, so that the acting range of the tips of the first cutting knife 18 and the second cutting knife 19 increases or decreases, thereby realizing the adjustment of the slotting width. Subsequently, the operator tightens the corresponding shaft seat 12 on the second round plate 17 to fix the position of the second round plate 17.

[0036] After adjusting the slotting width, the operator pulls out one or two push rods 26 below the first round plate 16 and the second round plate 17 according to the positions of the first round plate 16 and the second round plate 17 at this time. Then, the connecting rod 28 tilts to drive the corresponding support block 25 to move downward, leaving a position for the first cutting knife 18 and the second cutting knife 19 to perform slotting. The remaining push rods 26 are fixed to the workbench 24 by bolts, so that the support block 25 always remains flush with the top of the workbench 24.

[0037] After the adjustment is completed, the operator places the cardboard to be processed on the surface of the workbench 24. Subsequently, the operator starts the motor 13 to drive the main shaft 11 to rotate. Since the limiting block 20 is inserted into the corresponding sliding groove 15, the main shaft 11 will drive the first round plate 16 and the second round plate 17 to rotate. Then, the operator controls the electric cylinder 14 to retract, so that the main shaft 11 drives the first round plate 16 and the second round plate 17 to move downward close to the cardboard. The first cutting knife 18 and the second cutting knife 19 perform slotting on the cardboard. After the slotting is completed, the operator controls the electric cylinder 14 to extend to lift the first round plate 16 and the second round plate 17 back to their original positions.

[0038] During the rotation of the first round plate 16 and the second round plate 17, since the first limiting protrusion 23 and the second limiting protrusion 29 are interlaced and closely attached to each other, the first round plate 16 and the second round plate 17 will not deflect, so as to ensure that the tips of the first cutting knife 18 and the second cutting knife 19 always coincide, thereby ensuring the slotting effect of the first cutting knife 18 and the second cutting knife 19.

[0039] The above-mentioned motor 13, electric cylinder 14, etc. are mature existing technologies and will not be elaborated in this article.
