Description

Technical Field

[0001] The utility model belongs to the technical field of carton cutting, and in particular relates to an automatic high-precision carton cutting device. Background Art

[0002] Cardboard boxes come in various specifications and models. Commonly used cartons are three-layer and five-layer. Each layer is divided into lining paper, corrugated paper, core paper, face paper, etc. The color and feel of each paper are different, and the color and feel of paper produced by different manufacturers are also different. In the field of carton production, the cutting process is very important. In order to facilitate the assembly of cartons, cardboard usually needs to be cut before assembling the cartons, so that it can be better assembled into cartons.

[0003] The disclosure (announcement) number CN110434906A discloses a packaging carton cutting device, which discloses "including a workbench, a cardboard is placed on the top of the workbench, and a pressing mechanism is provided on the top of the workbench, and the pressing mechanism is tightly clamped with one side of the top of the cardboard, and the top of the workbench is fixedly installed with a vertical plate, and a horizontal plate is fixedly installed on one side of the vertical plate, and a slide rod is slidably installed on one side of the vertical plate, and a mounting plate is fixedly installed on one side of the slide rod, and a plurality of conical cutters arranged in a straight line are fixedly installed on the bottom of the mounting plate, and a cutting groove is opened on the top of the workbench, and the tops of the plurality of conical cutters are all located directly above the cutting groove, and a driving mechanism is fixedly installed on one side of the vertical plate, and the driving mechanism is connected to the slide rod for transmission, etc. The technical solution has the advantages of utilizing multiple conical cutters to reduce the contact area between the conical cutter and the cardboard, reduce the heat generated by friction, extend the service life of the conical cutter, and ensure that the cut cardboard is completely along the cutting line, with high cutting accuracy and high qualified rate of the cardboard".

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 As shown:

[0027] An automated high-precision carton cutting device comprises a workbench 1, a conveyor 2 fixed to one side of the workbench 1, and a cutting tool 3 arranged above the workbench 1 and away from the conveyor 2.

[0028] In this embodiment: the existing carton automated high-precision cutting equipment {publication (announcement) number}: CN110434906A discloses a packaging carton cutting device; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "although the design can reduce the contact area between the conical tool and the cardboard and reduce the heat generated by friction, in the actual cutting process, if the carton is not effectively fixed, the carton is very easy to move during the cutting process. Once the carton shakes, the cutting knife cannot be cut according to the predetermined trajectory, which will result in uneven cutting edges and seriously affect the appearance quality of the carton. At the same time, uneven cutting edges may also cause deviations in cutting dimensions, making the carton unable to meet design requirements, thereby affecting subsequent packaging use." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a cutting tool 3 and a fixing component 4 are added to this application document.

[0029] like Figure 1-Figure 5 As shown:

[0030] In combination with the above content, in order to prevent the carton from moving during the cutting process, a fixing assembly 4 is also included between the conveyor 2 and the cutting tool 3, and the fixing assembly 4 includes a cutting plate 41, a fixing frame 42, a rotating shaft 43, a moving gear 44, a driving motor 45, a moving rack 46, a push-pull frame 47, a wedge-shaped block 48, a fixing seat 49, a pressing rod 410 and an abutment wheel 411;

[0031] A cutting plate 41 is provided above the workbench 1, and a fixing frame 42 is fixed to the middle of the lower surface of the cutting plate 41. The internal rotation of the fixing frame 42 is connected to a rotating shaft 43. A moving gear 44 is fixed to the surface of the rotating shaft 43. The upper and lower sides of the moving gear 44 are symmetrically meshed and connected to a moving rack 46. The two sets of moving racks 46 are respectively connected to the fixing frame 42 in a sliding manner, and the two sets of moving racks 46 are arranged symmetrically about the moving gear 44. The surface of the fixing frame 42 is screwed to a driving motor 45, and the output end of the driving motor 45 is connected to one end of the rotating shaft 43. Fixedly connected, the two sets of movable racks 46 are respectively fixed with push-pull frames 47 at the opposite ends, and the four corners of the surface of the cutting plate 41 are fixedly connected with fixed seats 49. The top ends of the two sets of push-pull frames 47 pass through the lower surface of the cutting plate 41 and extend to the inside of the fixed seat 49, and are fixedly connected to the wedge-shaped stop block 48 that is slidably connected to the inside of the fixed seat 49. A pressing rod 410 is hinged inside the fixed seat 49, and the pressing rod 410 is rotatably connected to an abutment wheel 411 at one end close to the wedge-shaped stop block 48, and the abutment wheel 411 is slidably connected to the surface of the wedge-shaped stop block 48.

[0032] In this embodiment, when it is necessary to cut the carton, the conveyor 2 is first started, and then the carton to be processed is placed on the surface of the conveyor 2. The conveyor 2 can transport the carton to the surface of the cutting plate 41, and then the drive motor 45 is started. The drive motor 45 drives the rotating shaft 43 to rotate inside the fixed frame 42, and then drives the moving gear 44 to rotate synchronously inside the fixed frame 42, thereby driving the two sets of moving racks 46 to move relative to each other inside the fixed frame 42, and then the movement of the moving rack 46 can The push-pull frame 47 can be pulled to move in the push-pull groove opened inside the cutting plate 41 and the fixed seat 49, thereby driving the wedge-shaped block 48 to slide inside the fixed seat 49 and approach one side of the pressing rod 410. As the wedge-shaped block 48 moves, it can push the abutment wheel 411 at the end of the pressing rod 410, thereby pushing the pressing rod 410 to flip on the surface of the fixed seat 49, and make its pressing end approach the surface of the carton until the pressing rod 410 is completely pressed on the surface of the carton, and the four corners of the carton can be pressed and fixed.

[0033] Going further:

[0034] In combination with the above, in order to perform a full range of cutting operations on cartons, a rotating assembly 5 is also included, which is installed on the surface of the workbench 1. The rotating assembly 5 includes a moving seat 51, a limit block 52, a limit rod 53, an electric push rod 54, a rotating motor 55, a driving gear 56, a driven gear 57, a connecting column 58, a lifting frame 59 and an electric telescopic rod 510;

[0035] Limit rods 53 are symmetrically fixed on both sides of the surface of the workbench 1, and the surfaces of the two groups of limit rods 53 are slidably connected to the limit blocks 52. A moving seat 51 is fixed between the two groups of limit blocks 52. An electric push rod 54 is screwed to one side of the surface of the workbench 1 close to the moving seat 51, and the output end of the electric push rod 54 is fixedly connected to the lower surface of the moving seat 51. A driven gear 57 is rotatably connected to the middle part of the surface of the moving seat 51, and the surface of the driven gear 57 is meshed with the driving gear 56. A rotating motor 55 is screwed to the lower surface of the moving seat 51, and the output end of the rotating motor 55 is fixedly connected to the surface of the driving gear 56. Several groups of connecting columns 58 in a ring array are fixed on the surface of the driven gear 57, and the other end of the connecting column 58 is fixedly connected to the cutting plate 41. A lifting frame 59 is symmetrically screwed on both sides of the surface of the workbench 1, and the cutting tool 3 is slidably connected to the inside of the lifting frame 59. The top of the lifting frame 59 is screwed to an electric telescopic rod 510, and the output end of the electric telescopic rod 510 is fixedly connected to the surface of the cutting tool 3.

[0036] In this embodiment: after the four corners of the carton are pressed and fixed, the electric push rod 54 is first started, and the electric push rod 54 pushes the movable seat 51 to slide on the surface of the limit rod 53 through the limit blocks 52 at the four corners of the bottom, which can drive the movable seat 51 and the cutting plate 41 above it and the carton to move synchronously and approach the position of the cutting tool 3. When the cutting plate 41 and the carton are moved to the cutting position, the electric telescopic rod 510 is started, and the electric telescopic rod 510 drives the cutting tool 3 to slide along the surface of the lifting frame 59, and the carton fixed on the cutting plate 41 can be cut. After completing the cutting of one side of the carton, the cutting tool 3 is driven to reset by turning on the electric telescopic rod 510, and then the rotating motor 55 is started. The rotating motor 55 drives the driving gear 56 to rotate above the moving seat 51, and then drives the driven gear 57 to rotate on the surface of the moving seat 51. Then, with the cooperation of the connecting column 58, the cutting plate 41 and the carton fixed on its surface can be driven to rotate synchronously. When the position angle of the rotated carton needs to be cut again, the cutting tool 3 is driven to complete the cutting by starting the electric telescopic rod 510 again. This reciprocating process can enable the cutting tool 3 to cut the carton at different angles.

[0037] The working principle and use process of the present invention are as follows: when it is necessary to cut the cartons, first start the conveyor 2, and then place the cartons to be processed on the surface of the conveyor 2. The cartons can be transported to the surface of the cutting plate 41 through the conveying of the conveyor 2, and then start the driving motor 45. The driving motor 45 drives the rotating shaft 43 to rotate inside the fixed frame 42, and then drives the moving gear 44 to rotate synchronously inside the fixed frame 42, thereby driving the two sets of moving racks 46 to move relative to each other inside the fixed frame 42, and then the movement of the moving rack 46 can pull the push-pull frame 47 to move in the push-pull groove opened inside the cutting plate 41 and the fixed seat 49, thereby driving the wedge-shaped stop block 48 to slide inside the fixed seat 49 and approach one side of the pressing rod 410. As the wedge-shaped abutment 48 moves, it can push the abutment wheel 411 at the end of the pressing rod 410, and then push the pressing rod 410 to flip on the surface of the fixing seat 49, and make its pressing end approach the surface of the carton until the pressing rod 410 is completely pressed on the surface of the carton, so that the four corners of the carton can be pressed and fixed, which can prevent the carton from moving during the cutting process, so that the cutting tool 3 always cuts according to the predetermined trajectory, avoiding uneven cutting edges caused by the shaking of the carton, thereby ensuring the accuracy of the cutting size and improving the cutting accuracy. In addition, precise cutting can also reduce rework and correction due to dimensional deviation, thereby saving time and labor costs, improving production efficiency, speeding up the production process, and being able to complete cutting more quickly, making the entire production process smoother and shortening the production cycle.

[0038] When the four corners of the carton are pressed and fixed, the electric push rod 54 is first started, and the electric push rod 54 pushes the moving seat 51 to slide on the surface of the limit rod 53 through the limit blocks 52 at the four corners of the bottom, which can drive the moving seat 51 and the cutting plate 41 above it and the carton to move synchronously and approach the position of the cutting tool 3. When the cutting plate 41 and the carton are moved to the cutting position, the electric telescopic rod 510 is started, and the electric telescopic rod 510 drives the cutting tool 3 to slide along the surface of the lifting frame 59, so that the carton fixed on the cutting plate 41 can be cut. When the cutting work on one side of the carton is completed, the cutting tool 3 is reset by turning on the electric telescopic rod 510, and then the rotating motor 55 is started, and the rotating motor 55 drives the driving gear 56 to move The seat 51 rotates above the seat, thereby driving the driven gear 57 to rotate on the surface of the mobile seat 51, and then with the cooperation of the connecting column 58, it can drive the cutting plate 41 and the carton fixed on its surface to rotate synchronously. When the position angle of the rotated carton needs to be cut again, the electric telescopic rod 510 is started again to drive the cutting tool 3 to complete the cutting. This reciprocating process can enable the cutting tool 3 to cut the carton at different angles, thereby ensuring the flatness and verticality of each edge, and being able to process every corner of the carton, thereby performing a full range of cutting operations on the carton, preventing inadequate cutting, ensuring the integrity of the carton, improving the cutting quality, and reducing the cutting process. One-time full-range cutting can replace separate cutting operations in multiple directions, saving time and labor costs.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
