This device firmly clamps the cardboard box through the fixing component, can flexibly adjust the trimming position, collects paper scraps simultaneously, can adapt to cardboard boxes of different sizes, improves trimming accuracy and efficiency, and reduces the subsequent cleaning burden.

Description

Technical Field

[0001] This utility model relates to the technical field of cardboard box production and processing equipment, specifically a cardboard box rough edge trimming device. Background Technology

[0002] During the manufacturing process of cardboard boxes, irregular burrs and rough edges are often generated on the box edges due to cutting, creasing, and other processes. These burrs not only affect the appearance of the cardboard boxes but may also cause jamming on subsequent automated packaging lines or damage the printed patterns on the box surface due to friction during stacking and transportation, thus reducing the overall quality of the product. Currently, the treatment of cardboard box burrs mostly relies on manual trimming using tools such as utility knives. This method suffers from problems such as low efficiency, high labor intensity, inconsistent trimming quality, and safety hazards such as scratches to operators. Although some simple trimming equipment exists on the market, they are mostly single-cutting structures, making it difficult to adapt to the multi-sided burr treatment of cardboard boxes of different sizes. Furthermore, they lack effective limiting and fixing measures during trimming, which can easily lead to uneven trimming or damage to the box itself due to box displacement. At the same time, the generated waste debris is difficult to collect and clean up, affecting the working environment. Therefore, there is an urgent need for a specialized device that can automatically, efficiently, and safely trim burrs on cardboard boxes of different specifications and simultaneously collect waste.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1 - Figure 4 A cardboard box edge trimming device includes a workbench 1, a trimming component, and a fixing component. The workbench 1 has multiple support legs 2 at its bottom, a mounting frame 3 on one side of its top, and a fixing component on the other side of its top. The mounting frame 3 has a second groove 301 on its inner wall at its top. A first bidirectional lead screw 4 is installed in the second groove 301. One end of the first bidirectional lead screw 4 is rotatably connected to the inner wall of the second groove 301, and the other end is connected to the output end of a first motor 401 installed on the side wall of the mounting frame 3. A first limiting block 403 is installed in the middle of the first bidirectional lead screw 4 in the second groove 301. First connecting blocks 402 are threaded to both sides of the first limiting block 403 on the first bidirectional lead screw 4. An electric telescopic rod 5 is fixedly connected to the bottom of the first connecting block 402. The trimming component is installed at the bottom of the electric telescopic rod 5. The trimming assembly includes a connecting plate 6, a telescopic rod 7, a pressure plate 9, and a trimming blade 10. The bottom of the electric telescopic rod 5 is fixedly connected to the top of the connecting plate 6. Both ends of the bottom of the connecting plate 6 are fixedly connected to the top of the telescopic rod 7. A spring 8 is sleeved on the outer periphery of the telescopic rod 7. The bottom of the telescopic rod 7 is fixedly connected to the top of the pressure plate 9. The trimming blade 10 is fixedly connected to the bottom side of the connecting plate 6 away from the telescopic rod 7.

[0015] Through the above technical solution, by setting the second groove 301 on the top of the inner wall of the mounting frame 3, a stable installation space is provided for the first bidirectional lead screw 4. When the first motor 401 drives the first bidirectional lead screw 4 to rotate, the first limiting block 403 can limit the movement range of the first connecting blocks 402 on both sides to avoid collision. At the same time, the first connecting block 402 can drive the electric telescopic rod 5 and the bottom trimming assembly to move synchronously, realizing flexible adjustment of the trimming position to adapt to the trimming needs of different sized cartons. In the trimming assembly, the telescopic rods 7 at both ends of the bottom of the connecting plate 6 cooperate with the springs 8 sleeved on the outer periphery. When the electric telescopic rod 5 drives the connecting plate 6 to descend, the pressure plate 9 will first contact the cartons. Then the telescopic rods 7 retract and the springs 8 compress. The elastic force of the springs 8 makes the pressure plate 9 press the cartons tightly, realizing the stable limiting of the trimming part of the cartons and preventing the cartons from shifting during trimming. The trimming blade 10 at the bottom of the connecting plate 6 can accurately complete the trimming operation after the pressure plate 9 limits the trimming.

[0016] This utility model provides a technical solution in which the workbench 1 is a U-shaped workbench. The inner wall of the workbench 1 has two opposite first grooves 101. A transmission screw 11 is provided in the first groove 101. One end of the transmission screw 11 is rotatably connected to the inner wall of the first groove 101, and the other end is connected to the output end of the second motor 1101 provided on the side wall of the workbench 1. A second connecting block 1102 is threaded on the transmission screw 11. A fixing component is connected to the side of the second connecting block 1102 near the workbench 1. The fixing assembly includes a fixing platform 12 and a limiting plate 14. The second connecting block 1102 is fixedly connected to the side wall of the fixing platform 12 near the worktable 1. A third groove 1201 is provided in the middle of the top of the fixing platform 12. A second bidirectional lead screw 13 is provided in the third groove 1201. One end of the second bidirectional lead screw 13 is rotatably connected to the inner wall of the third groove 1201, and the other end is drivenly connected to the output end of the third motor 1301 provided on the side wall of the fixing platform 12. A second limiting block 1302 is provided in the middle of the second bidirectional lead screw 13 in the third groove 1201. A third connecting block 1303 is threadedly connected to both sides of the second limiting block 1302 on the second bidirectional lead screw 13. The top of the third connecting block 1303 is fixedly connected to the bottom of the limiting plate 14. Multiple second trimming slots 1202 are provided on both ends of the fixed platform 12 near the second connecting block 1102, and multiple first trimming slots 102 are provided on the lower part of the mounting bracket 3 on the workbench 1, corresponding to the second trimming slots 1202.

[0017] Through the above technical solution, the U-shaped workbench 1, in conjunction with the transmission screws 11 in the first grooves 101 on both sides of the inner wall, can be driven by the second motor 1101 to drive the fixing component to move smoothly through the second connecting block 1102, accurately conveying the carton to the trimming area below the mounting frame 3. In the fixing component, the third motor 1301 drives the second bidirectional screw 13 in the third groove 1201 to rotate. With the help of the third connecting blocks 1303 on both sides of the second limiting block 1302, the limiting plate 14 can move synchronously in opposite directions, thereby adapting to cartons of different widths and achieving stable clamping. The second trimming grooves 1202 at both ends of the fixing table 12 and the corresponding first trimming grooves 102 on the workbench 1 can provide a space for the trimming blade 10 during trimming, avoiding collision between the trimming blade 10 and the fixing table 12 or the workbench 1, while facilitating the collection of paper scraps by falling through the groove.

[0018] This utility model provides a technical solution in which a collection box 15 is provided at the bottom of the workbench 1 below the mounting bracket 3. An opening is provided on the side of the collection box 15 away from the workbench 1. A drawer 16 is fitted inside the collection box 15. The drawer 16 is slidably connected to the inner wall of the collection box 15 through slide rails 17 provided on the two side walls.

[0019] Through the above technical solution, the collection box 15 at the bottom of the workbench 1 below the mounting frame 3 can receive paper scraps falling from the first trimming slot 102 and the second trimming slot 1202, preventing paper scraps from scattering onto the workbench 1 or the ground and causing pollution; the drawer 16 inside the collection box 15 is slidably connected to the inner wall of the collection box 15 through the slide rails 17 on both sides. When the paper scraps accumulate to a certain amount in the drawer 16, the drawer 16 can be directly pulled out from the opening of the collection box 15 to quickly complete the paper scrap cleaning operation.

[0020] The working principle of this utility model is as follows: First, place the cardboard box to be cut on the fixed platform 12, start the third motor 1301, which drives the second bidirectional lead screw 13 to rotate in the third groove 1201, so that the third connecting blocks 1303 on both sides of the second limiting block 1302 drive the limiting plate 14 to move relative to each other until the cardboard box is clamped and fixed. Then start the second motor 1101, which drives the transmission lead screw 11 to rotate in the first groove 101, and drives the fixed platform 12 and the cardboard box to move along the worktable 1 through the second connecting block 1102 until the position of the cardboard box to be cut is moved to the bottom of the mounting frame 3. Then start the first motor 401, and the first bidirectional lead screw 4 rotates in the second groove 301. The first connecting blocks 402 on both sides of the first limiting block 403 drive the electric telescopic rod 5 and the cutting assembly to move, and adjust the cutting blade 10 to the corresponding cutting position. The electric telescopic rod 5 extends, causing the connecting plate 6 to descend. When the pressure plate 9 contacts the carton, the telescopic rod 7 retracts and the spring 8 is compressed. The pressure plate 9 limits the carton. The trimming blade 10 continues to descend to trim the rough edges of the carton. The paper scraps generated by trimming fall into the drawer 16 inside the collection box 15 through the second trimming groove 1202 and the first trimming groove 102. After trimming, all parts are reset. The drawer 16 can be pulled out through the slide rail 17 to clean up the paper scraps.
