Utility Model Content

[0004] The purpose of the present application is to provide a cutting mechanism for carton production, which solves the problem in the prior art that during downward cutting, the carton is prone to deviation and causes cutting errors, thereby achieving the purpose of improving the overall cutting accuracy.

[0007] Preferably, the side wall of the L-shaped fixing frame is provided with a plurality of sliding grooves, and sliding blocks are movably installed inside the sliding grooves, and the free ends of the plurality of sliding blocks are fixedly connected to the same pressing member, and the pressing member is used to quickly press down the carton.

[0008] Preferably, a counterweight block is arranged inside the lower pressing member, and a plurality of magnetic suction members are fixedly connected to the top and the bottom of the counterweight block, and the magnetic suction members on two adjacent counterweight blocks are matched.

[0009] Preferably, two communication ports are provided inside the cutting frame, and both ends of the driving plate and the adjusting plate are slidably connected inside the communication ports.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] 1. The utility model has a reasonable structure. By setting a support plate connected with several adjustment plates, before using it, the connecting slide rail can be controlled by an external controller to make the connecting slide rail drive the support plate to move. At this time, the support plate can drive the support plate to rotate under the action of the driving force of the connecting slide rail, and change the distribution state of the support plate between the two adjustment plates. When the adjustment plate is gradually perpendicular to the driving plate, the adjustment plate can effectively convert the driving force of the connecting slide rail into thrust acting on the adjustment plates at both ends, so that the adjustment plates at both ends are away from each other, and then the relative distance between the overall adjustment plate and the two driving plates is changed, thereby meeting the placement requirements of larger cartons.

[0014] 2. In the present invention, an L-shaped fixing frame is provided, and the L-shaped fixing frame can be pulled during adjustment, so that the force is applied to the fixing frame to slide along the guide groove through the guide block. When the four L-shaped fixing frames slide to the four corners of the carton, the sliding block and the pressing member will fall rapidly along the sliding groove under the action of their own gravity, so that the pressing member can be stably placed above the carton. At this time, the gravity of the pressing member itself will press down and limit the top of the pressing member, thereby improving its fixing effect, allowing the L-shaped fixing frame to effectively limit the position of the carton, making it more stable during cutting, avoiding the possibility of its force being offset or tilted, and improving the overall cutting stability and accuracy to a certain extent.

[0027] Combine the following Figure 1-4 The embodiment shown describes the technical solution of the utility model:

[0028] It includes a cutting frame 1, and two driving plates 2 are arranged inside the cutting frame 1, and a plurality of adjustment plates 3 are arranged on the opposite side of the two driving plates 2. The side plate of the adjustment plate 3 is provided with a mounting opening 4, and the inside of the mounting opening 4 is connected with a support plate 5 through a damping shaft, and the free end of the support plate 5 is connected to the side wall of another adjustment plate 3 through a connecting slide rail 6, and the support plate 5 is rotatably connected between the two adjustment plates 3, the side wall of the driving plate 2 is fixedly installed with a guide groove 8, and the inside of the guide groove 8 is slidably connected with an L-shaped fixing frame 10 through two guide blocks 9, and the four L-shaped fixing frames 10 are relatively arranged, and the four L-shaped fixing frames 10 are distributed in a rectangular structure.

[0029] During its use, the cutting frame 1 can be directly placed on a plane, so that the connecting slide rail 6 can be directly controlled by an external controller, so that the connecting slide rail 6 can effectively drive the support plate 5 to move. At this time, the support plate 5 can drive the support plate 5 to rotate under the action of the driving force of the connecting slide rail 6, thereby changing the distribution state of the support plate 5 between the two adjustment plates 3. When the adjustment plate 3 is gradually perpendicular to the driving plate 2, the adjustment plate 3 can effectively convert the driving force of the connecting slide rail 6 into a thrust acting on the adjustment plates 3 at both ends, so that the adjustment plates 3 at both ends are separated from each other, and then the relative distance between the overall adjustment plate 3 and the two driving plates 2 is changed, so as to meet the placement requirements of larger cartons. After the carton is placed, the L-shaped fixing frame 10 can be directly pulled to make it slide along the guide groove 8 through the guide block 9 under force. When the four L-shaped fixing frames 10 slide to the four corners of the carton, the L-shaped fixing frame 10 can effectively limit the position of the carton, making it more stable during cutting, avoiding the possibility of its force being offset or tilted, and improving the stability and accuracy of its overall cutting to a certain extent.

[0030] A positioning plate 11 is fixedly connected to the inside of the guide groove 8 , and a plurality of positioning holes 12 are opened on the positioning hole 12 . An electric push rod 13 is fixedly installed on the side wall of the guide block 9 , and the free end of the electric push rod 13 can be inserted into the inside of the positioning hole 12 .

[0031] When the L-shaped fixing frame 10 is pulled for adjustment, the L-shaped fixing frame 10 can effectively slide along the guide groove 8 under the action of its force. When the L-shaped fixing frame 10 is adjusted to a suitable position, the electric push rod 13 can be directly controlled by an external controller, so that the electric push rod 13 is extended under the action of the external driving force, and then the free end of the electric push rod 13 is inserted into the interior of the positioning hole 12, so that a limiting structure is provided between the guide block 9 and the positioning plate 11, and the position of the L-shaped fixing frame 10 is limited, thereby ensuring the stability of the L-shaped fixing frame 10 during use and improving its clamping and limiting effect.

[0032] The side wall of the L-shaped fixing frame 10 is provided with a plurality of sliding grooves 14, and sliding blocks 15 are movably installed inside the sliding grooves 14. The free ends of the plurality of sliding blocks 15 are fixedly connected with the same pressing member 16, and the pressing member 16 is used to quickly press down the carton.

[0033] When the L-shaped fixing frame 10 moves to the four corners of the carton, you can directly let go, so that the sliding block 15 and the pressing piece 16 will fall quickly along the sliding groove 14 under the action of their own gravity, so that the pressing piece 16 can be stably placed above the carton. At this time, the gravity of the pressing piece 16 itself will press down and limit the top of the pressing piece 16, thereby improving its fixing effect.

[0034] A counterweight block 17 is disposed inside the pressing member 16 , and a plurality of magnetic elements 18 are fixedly connected to the top and bottom of the counterweight block 17 , and the magnetic elements 18 on two adjacent counterweight blocks 17 are matched.

[0035] During its use, the counterweight block 17 of appropriate specifications and gravity can be rotated autonomously according to the specific downward pressure requirements of different cartons, and then several selected counterweight blocks 17 can be connected through the magnetic suction part 18, so that the counterweight block 17 can be stably placed inside the downward pressure piece 16, so as to quickly press down the carton, thereby improving the flexibility and adaptability of its overall downward pressure structure, and then meeting the use of cartons of different specifications.

[0036] Two communication ports 19 are formed inside the cutting frame 1 , and both ends of the driving plate 2 and the adjusting plate 3 are slidably connected inside the communication ports 19 .

[0037] The setting of the connecting port 19 can effectively limit the moving trajectory of the driving plate 2 and the adjusting plate 3 when the driving plate 2 and the adjusting plate 3 are moved under force, so that the driving plate 2 and the adjusting plate 3 are more stable, avoiding the possibility of displacement during force adjustment, and improving their stability during adjustment.

[0038] A concave frame 20 is fixedly connected to the top of the cutting frame 1 , and a cutting machine body 22 is connected to the top of the concave frame 20 via a linear slide rail 21 . The cutting machine body 22 is used to quickly cut the cartons on the cutting frame 1 .

[0039] During its use, the linear slide 21 can be directly controlled by an external controller according to the specific needs of different cartons, so that the linear slide 21 effectively drives the cutting body 22 to move, and then the carton is quickly cut, thereby improving the convenience of cutting.

[0040] Four footrests 23 are fixedly connected to the bottom of the cutting frame 1 , and a lifting cylinder 24 is fixedly connected to the bottom of the footrests 23 . The lower ends of the four lifting cylinders 24 are fixedly connected to the same anti-skid pad 25 , and the anti-skid pad 25 is horizontally distributed with the cutting frame 1 .

[0041] During its use, the anti-slip mat 25 can be directly placed on a flat surface, so that the lifting cylinder 24 can be effectively controlled by an external controller, so that the lifting cylinder 24 can push the cutting frame 1 to rise and fall quickly under the action of its control force, thereby effectively changing the height of the cutting frame 1, so that the cutting frame 1 can be quickly adapted to the conveying mechanisms and other equipment at different heights on the production line.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
