Description

Technical Field

[0001] This application relates to the field of carton cutting, and more specifically, to a fully automated carton cutting machine. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and nailed or glued to make corrugated boxes. Corrugated boxes are one of the most widely used packaging products. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging.

[0003] Patent document CN217226831U discloses a fully automated corrugated carton cutting machine, which relates to the field of cutting machines. This fully automated corrugated carton cutting machine includes a cutting platform and a quick-positioning mechanism. A supporting column is fixedly connected to the top of the cutting platform, and a supporting top plate is fixedly connected to the top of the supporting column. An electric push rod body is fixedly connected to the top of the supporting top plate. In the aforementioned application, the electric push rod body drives the push rod downwards, which in turn drives the cutter lifting support arm to descend, allowing the cutter body to cut the corrugated carton shell. However, after cutting, the cut-off portion needs to be manually removed, which is inconvenient for automatically separating the two cut parts after cutting, thus hindering material replacement efficiency.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] See Figures 1-4This embodiment provides a fully automated carton cutting machine, including a frame 1. A conveyor belt device 2 is installed on the inner surface of the frame 1. The conveyor belt device 2 includes two drive rollers and a drive belt, which are connected between the two drive rollers. There are two sets of conveyor belt devices 2. A support groove 3 is provided between the two sets of conveyor belt devices 2. The support groove 3 is specifically a long strip with a cutting groove in the middle adapted to the cutter 509. The support groove 3 is fixedly connected to the inner surface of the frame 1. A support frame 4 is fixedly connected above the frame 1. The support frame 4 is door-frame shaped. A cutting assembly 5 is installed on the inner surface of the support frame 4. The cutting assembly 5 includes an electric push rod 501, which is fixedly connected to the top of the inner surface of the support frame 4. A lifting seat 502 is fixedly connected to the lower end of the electric push rod 501. The lifting seat 502 is slidably connected to the inner surface of the support frame 4. The inner surface of the support frame 4 is provided with a slide rail for the sliding of the lifting seat 502. The front of the lifting seat 502 is fixedly connected to the sliding plate 504 via a connecting rod 503. The right side of the sliding plate 504 is elastically connected to the rack 506 via a spring 505. The teeth on the rack 506 have beveled surfaces. The left side of the rack 506 is fixedly connected to the limit rod 507, which movably passes through the right side of the sliding plate 504. The rear of the sliding plate 504 is slidably connected to the support bar 508, which is provided with a slide rail for the sliding plate 504 to slide. The support bar 508 is fixedly connected to the front of the frame 1. The cutting assembly 5 also includes a cutter 509, which is fixedly connected to the bottom of the lifting seat 502. The bottom of the frame 1 is fixedly connected to the support leg 6.

[0024] In practical use, the corrugated paper to be cut is first placed on the conveyor belt device 2 on the frame 1. The corrugated paper will be on the transmission belt in the conveyor belt device 2. At this time, the electric push rod 501 is activated, which pushes the lifting seat 502 to descend. The lifting seat 502 drives the cutter 509 to descend and, together with the support groove 3, cuts the corrugated paper. After cutting, the electric push rod 501 pulls the lifting seat 502 to rise. The lifting seat 502 drives the connecting rod 503 to slide the sliding plate 504. The slide plate 504 moves upward on the support bar 508, and the sliding plate 504 drives the limit rod 507 to raise the rack 506. The rack 506 moves the ratchet 801 to rotate the right-side rotating shaft 701 clockwise. The right-side rotating shaft 701 drives the gear 702 to rotate the left-side rotating shaft 701 counterclockwise. The rotation of the two rotating shafts 701 drives the transmission roller in the conveyor belt device 2, so that the two transmission belts drive each other in opposite directions, thereby separating the two cut parts so that the user can remove the waste.

[0025] Example 2

[0026] See Figures 1-4Based on Embodiment 1, a rotating assembly 7 is provided on the front of the frame 1. The rotating assembly 7 includes a rotating shaft 701, which penetrates and is rotatably connected to the front of the frame 1. A bearing is provided between the rotating shaft 701 and the frame 1. There are two rotating shafts 701, which are respectively penetrated and fixedly connected to two sets of conveyor belt devices 2. The two rotating shafts 701 are respectively penetrated and fixedly connected to adjacent drive rollers in the two sets of conveyor belt devices 2. The other two drive rollers in the two sets of conveyor belt devices 2 are rotatably connected to the inner surface of the frame 1. Teeth are fixedly connected to the rear ends of the two rotating shafts 701. The wheel 702 has a shorter front end on the left side of the rotating shaft 701. The two gears 702 mesh with each other. A limit assembly 8 is provided on the front of the rotating shaft 701. The limit assembly 8 includes a ratchet 801, which is fixedly connected to the front end of the rotating shaft 701 on the right side. The ratchet 801 meshes with the right side of the rack 506. When the rack 506 rises, it can drive the ratchet 801 to rotate clockwise. The limit assembly 8 also includes a pawl 802, which is rotatably connected to the front of the support frame 4. The pawl 802 meshes with the upper part of the ratchet 801 and is used to limit the ratchet 801 so that it cannot rotate counterclockwise.

[0027] In practical use, when the electric push rod 501 pushes the lifting seat 502 down, the rack 506 descends and pushes against the ratchet 801. At this time, the spring 505 is compressed, and the rack 506 slides downward on the left side of the ratchet 801. After being subjected to sliding friction, the ratchet 801 rotates counterclockwise. At this time, the pawl 802 limits the ratchet 801, preventing it from rotating counterclockwise. Consequently, the rotating shaft 701 on the right side cannot rotate counterclockwise, and the rotating shaft 701 on the left side cannot rotate clockwise under the action of the gear 702. This prevents the conveyor belt device 2 from transmitting power when the lifting seat 502 descends, thus ensuring the stability of the cutting.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
