Description

Technical Field

[0001] This utility model belongs to the field of packaging paper box processing technology, and in particular relates to a packaging paper box edge trimming device. Background Technology

[0002] Packaging boxes refer to various paper packaging containers, such as cardboard boxes, that are stored and preserved for packaging products. They are an environmentally friendly and recyclable packaging material. In the production process of packaging boxes, the edge trimming device is a professional piece of equipment used in the production of packaging cartons. Its main function is to cut and trim the edges of the cardboard boxes to ensure accurate dimensions and smooth edges. This device is widely used in the packaging box processing field and can improve production efficiency and product quality.

[0003] A search revealed a Chinese patent (publication number: CN222844884U) that discloses a packaging cardboard box trimming device, including a working platform and a fixed plate on the working platform. The bottom side of the fixed plate has a through groove for the cardboard box to pass through. Two clamping members are movably connected to the side wall of the fixed plate. An adjustment mechanism for driving the two clamping members to move relative to each other is fixedly connected to the side wall of the fixed plate. When cutting the cardboard, it is placed on the working platform, the adjustment mechanism is activated, and the two clamping members limit the two sides of the cardboard. The two vertical cutting members are activated to cut the two sides of the cardboard respectively. After the two sides of the cardboard are cut, the clamping members no longer limit the cardboard, allowing the cardboard to pass through the through groove at the bottom of the fixed plate. The cut sides of the cardboard are then aligned with the side wall of the positioning plate. After adjusting to the appropriate position, the horizontal cutting members are activated to cut the other two sides of the cardboard. During the cutting process, positioning errors can be effectively avoided to prevent deviations in the cutting position.

[0004] However, because the device is equipped with mutually perpendicular horizontal and vertical cutters, it can only cut cardboard horizontally and vertically, making it difficult to quickly switch cutting modes or adapt to different materials. It is not capable of handling complex tasks that require multi-directional and multi-angle cutting (such as irregular shape cutting), which reduces the applicability of the equipment. Therefore, a packaging carton edge trimming device is needed to solve the above problems. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] like Figures 1 to 4 As shown, this utility model embodiment provides a packaging cardboard box trimming device, including:

[0028] The device body 1 includes a worktable 11 and a pair of fixed rods 12. The pair of fixed rods 12 are respectively vertically mounted on the upper surface of the worktable 11. The worktable 11 has a circular groove 111. The worktable 11 is made of non-magnetic material. The pair of fixed rods 12 have a first moving groove 121 on one end face of opposite sides.

[0029] The cutting mechanism 2 includes a moving rod 21, a pair of cutting blades 22 and a pair of blade holders 23. The moving rod 21 has a first sliding groove 211. The upper end of the blade holder 23 is slidably disposed in the first sliding groove 211. Each cutting blade 22 is detachably mounted on each blade holder 23. The two ends of the moving rod 21 are respectively movably disposed in a pair of first moving grooves 121.

[0030] Rotation mechanism 3 includes a rotating disk 31, a circular electromagnet 32 ​​and a fixed frame 33. The circular electromagnet 32 ​​is rotatably mounted on the fixed frame 33. The rotating disk 31 is placed at a predetermined distance below the circular electromagnet 32. The rotating disk 31 is rotatably disposed in the circular groove 111. The fixed frame 33 is fixedly mounted on the upper end of the worktable 11. The rotating disk 31 is made of magnetic material.

[0031] In this embodiment, firstly, the circular electromagnet 32 ​​loses its magnetic force when de-energized, and the worker places the paper to be trimmed between the rotating disk 31 and the circular electromagnet 32; after the circular electromagnet 32 ​​is energized, it generates magnetic force, which in turn attracts the rotating disk 31 below the paper. In this way, the paper is clamped between the magnetically attracted circular electromagnet 32 ​​and the rotating disk 31; the driving device drives the rotating disk 31 to rotate in the circular groove 111, thereby enabling the cutting blade 22 to cut the paper in multiple directions and angles, expanding the applicability of the equipment;

[0032] Specifically, the cutting mechanism 2 also includes two pairs of connecting rods 24, a pair of moving cylinders 25, and two pairs of conveyor blocks 26. The upper surface of the worktable 11 also has two pairs of second sliding grooves 112. The fixed rod 12 has a second moving groove 122 on the adjacent side wall with the first moving groove 121. Each pair of second moving grooves 122 is symmetrically distributed with each fixed rod 12 as the center. The conveyor blocks 26 are movably disposed in the second sliding grooves 112. The two ends of the connecting rod 24 are rotatably connected to the conveyor blocks 26 and one end of the fixed rod 12, respectively. The fixed rod 12 is movably disposed in the second moving grooves 122. The output shaft of each moving cylinder 25 is connected to one of the conveyor blocks 26 in each pair.

[0033] In this embodiment, after activation, the moving cylinder 25 drives the belt moving block 26 to move along the second slide groove 112. At this time, the angle between the connecting rod 24 and the fixed rod 12 changes, thereby driving the belt moving rod 21, which is rotatably connected to the connecting rod 24, to move down along the first moving groove 121; so that the cutting blade 22 moves to cut the paper on the worktable 11, reflecting the degree of automation of the equipment.

[0034] Specifically, the cutting mechanism 2 also includes a turntable 27, a rotating gear 28, and a rotating motor 29. The upper end of the blade holder 23 has a shifting column 231. The turntable 27 has a pair of circumferentially distributed inclined grooves 271, a fixed cylinder 272, and a toothed ring 273. The toothed ring 273 is fixedly installed on the upper end of the fixed cylinder 272. The middle position of the shifting rod 21 has a fixed column 212, which is inserted into the fixed cylinder 272. The output shaft of the rotating motor 29 is connected to the rotating gear 28. The rotating gear 28 meshes with the toothed ring 273. The rotating gear 28 is rotatably installed on the fixed column 212. The shifting column 231 is placed in the inclined groove 271.

[0035] In this embodiment, after startup, the rotating motor 29 drives the rotating gear 28 to rotate, which in turn drives the gear ring 273 to rotate, which in turn drives the turntable 27 to rotate axially around the fixed column 212. The rotating turntable 27 drives the moving column 231 to slide along the inclined groove 271, so that a pair of blade holders 23 move towards or away from each other along the first sliding groove 211. In this way, by setting the rotating gear 28, gear ring 273 and turntable 27, the purpose of adjusting the distance between a pair of cutting blades 22 is achieved, further expanding the applicability of the equipment.

[0036] Specifically, the turntable 27 is provided with a plurality of circumferentially distributed positioning holes 274 at intervals, and the moving rod 21 has a positioning post 213 and a support rod 214. The positioning post 213 is vertically mounted on the support rod 214 and the positioning post 213 is inserted into the positioning hole 274.

[0037] In this embodiment, after the turntable 27 rotates to the designated position, the driving device drives the positioning post 213 to move downward toward the turntable 27 until the positioning post 213 is inserted into the positioning hole 274; by setting the positioning post 213, the turntable 27 and the moving rod 21 are fixed to each other, ensuring that the cutting is carried out normally;

[0038] Specifically, the main body 1 of the device also includes a pair of positioning plates 13, and the worktable 11 has a pair of oppositely arranged positioning grooves 113, with each positioning plate 13 slidably disposed in each positioning groove 113;

[0039] Specifically, the main body 1 of the device also includes a pair of springs 14 and a pair of connecting posts 15. One end of each connecting post 15 is rotatably mounted on the side wall of each positioning plate 13. The springs 14 are inserted into the connecting posts 15. The two ends of the springs 14 are connected to the positioning plate 13 and the inner wall of the positioning groove 113. The connecting post 15 has a limiting block 151 at the end away from the positioning plate 13. The worktable 11 has a limiting groove 114 on the side wall forming the positioning groove 113. The limiting block 151 is adapted to the limiting groove 114.

[0040] In this embodiment, the worker pulls the connecting column 15 toward the direction of the limiting groove 114 until the limiting block 151 passes the limiting groove 114, and then rotates the connecting column 15 so that the limiting block 151 abuts against the side wall of the workbench 11. At this time, the spring 14 is compressed, and the worker places the paper to be trimmed between a pair of positioning plates 13. Finally, the worker rotates the connecting column 15 in the opposite direction. Under the elastic force of the spring 14, the pair of positioning plates 13 move toward each other along the positioning groove 113 so that the paper is clamped by the pair of positioning plates 13.

[0041] The working principle of this utility model is as follows:

[0042] First, the circular electromagnet 32, now de-energized, loses its magnetic force. The worker places the paper to be trimmed between the rotating disk 31 and the circular electromagnet 32. Then, the worker pulls the connecting column 15 towards the limit groove 114 until the limit block 151 passes the limit groove 114. The worker then rotates the connecting column 15 so that the limit block 151 abuts against the side wall of the worktable 11. At this time, the spring 14 is compressed. The worker places the paper to be trimmed between a pair of positioning plates 13. Finally, the worker rotates the connecting column 15 in the opposite direction. Under the elastic force of the spring 14, the pair of positioning plates 13 move towards each other along the positioning groove 113 so that the paper is clamped by the pair of positioning plates 13.

[0043] After the paper is clamped by the positioning plate 13, the circular electromagnet 32 ​​is energized to generate magnetic force, which attracts the rotating disk 31 below the paper. In this way, the paper is clamped by the magnetically attracted circular electromagnet 32 ​​and rotating disk 31. Finally, the worker pulls the connecting column 15 towards the limit groove 114 again until the limit block 151 passes the limit groove 114, and then rotates the connecting column 15 so that the limit block 151 abuts against the side wall of the worktable 11. In this way, by setting the positioning plate 13, the paper is placed in the middle position of the worktable 11, ensuring that the trimming process proceeds normally.

[0044] After the paper is clamped by the circular electromagnet 32 ​​and the rotating disk 31, the motor and other driving devices drive the rotating disk 31 to rotate in the circular groove 111, thereby realizing multi-directional and multi-angle cutting of the paper and expanding the applicability of the equipment.

[0045] After startup, the rotating motor 29 drives the rotating gear 28 to rotate, which in turn drives the gear ring 273 to rotate, which in turn drives the turntable 27 to rotate axially around the fixed column 212. The rotating turntable 27 drives the moving column 231 to slide along the inclined groove 271, so that a pair of blade holders 23 move towards or away from each other along the first sliding groove 211. In this way, by setting the rotating gear 28, gear ring 273 and turntable 27, the purpose of adjusting the distance between a pair of cutting blades 22 can be achieved, further expanding the applicability of the equipment.

[0046] After the turntable 27 rotates to the designated position, the drive device drives the positioning pin 213 to move downward toward the turntable 27 until the positioning pin 213 is inserted into the positioning hole 274; by setting the positioning pin 213, the turntable 27 and the moving rod 21 are fixed to each other to ensure that the cutting is carried out normally;

[0047] After startup, the moving cylinder 25 drives the belt moving block 26 to move along the second slide groove 112. At this time, the angle between the connecting rod 24 and the fixed rod 12 changes, thereby driving the belt moving rod 21, which is rotatably connected to the connecting rod 24, to move down along the first moving groove 121; so that the cutting blade 22 moves to cut the paper on the worktable 11, reflecting the degree of automation of the equipment.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
