Description

Technical Field

[0001] This utility model relates to the field of notebook computer packaging production technology, and in particular to a cutting device for notebook computer packaging production. Background Technology

[0002] Laptop packaging primarily uses boxes, which are mostly made of cardboard. During the production of these boxes, a cutting device is needed to cut strips of cardboard to a specified length. The boxes are then assembled. However, current cutting devices require measuring the cutting length each time they are cut, which makes the operation cumbersome and reduces the efficiency of continuous cutting.

[0003] For example, a cutting device for laptop packaging production disclosed in Chinese patent literature (publication number: CN211683714U) adjusts the back-and-forth movement of the baffle by observing the scale grooves on both sides of the top of the workbench. The cardboard is placed on the workbench and pushed backward so that the back of the cardboard is flush with the front of the baffle. At this time, the length of the cardboard cut by the top cutter is the same as the scale of the corresponding groove, thus achieving precise cutting. Through the setting of the sleeve and sleeve, a movable telescopic rod is formed between the baffle and the back plate, so that the baffle maintains a linear movement when moving back and forth, reducing errors and achieving the purpose of convenient use.

[0004] However, in actual operation, it is usually necessary to continuously cut the same length of cardboard. However, each cut requires observation, alignment and movement, which makes the cutting process cumbersome. Furthermore, the cut cardboard needs to be manually removed before cutting can continue, which not only increases manual labor but also seriously affects the continuity of cutting. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies. Currently, when cutting cardboard for laptop packaging, repeated observation is required, and the cardboard needs to be manually removed after each cut, resulting in cumbersome operation and reduced cutting continuity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cutting device for producing laptop packaging includes a cutting table, an unloading mechanism above the cutting table, and the unloading mechanism includes a mounting block, the lower end of which is fixedly connected to the upper end of the cutting table.

[0008] The upper end of the mounting block is provided with a mounting groove. A symmetrically distributed rotating rod is rotatably connected to one side inner wall of the mounting groove via a bearing. Friction wheels arranged in a linear array are fixedly sleeved on the outside of the rotating rod. One end of one of the rotating rods is rotatably connected to a support block via a bearing. The lower end of the support block is fixedly connected to the inner bottom wall of the mounting groove.

[0009] A fixed-distance cutting mechanism is provided above the cutting table, and the fixed-distance cutting mechanism is located above the unloading mechanism.

[0010] Preferably, a servo motor is fixedly mounted on the inner bottom wall of the mounting groove via a mounting base, and the output shaft of the servo motor is fixedly connected to one end of another rotating rod via a coupling. A first hydraulic cylinder, symmetrically distributed, is fixedly mounted on the inner bottom wall of the mounting groove.

[0011] Preferably, one end of each of the two piston rods of the first hydraulic cylinders is fixedly connected to a lifting cover, the inner wall of the lifting cover is movably sleeved with the outer side of the mounting block, and the front side of the lifting cover is provided with a scale groove.

[0012] Preferably, the upper end of the lifting hood is provided with through slots arranged in a linear array, the back of the lifting hood is fixedly connected to a discharge inclined plate, a synchronous pulley is fixedly sleeved on the outside of the rotating rod, and a synchronous belt is driven to the outside of both synchronous pulleys.

[0013] Preferably, the fixed-distance cutting mechanism includes a top plate, and the lower end of the top plate is fixedly connected to a support rod distributed in a rectangular array, and the lower ends of the multiple support rods are fixedly connected to the upper end of the cutting table.

[0014] Preferably, symmetrically distributed servo electric cylinders are fixedly installed at the lower end of the top plate. One end of the movable rod of the servo electric cylinder is fixedly connected to a moving plate. The lower ends of the two moving plates are fixedly connected to baffles, and the lower ends of the baffles are in contact with the upper end of the lifting cover.

[0015] Preferably, a second hydraulic cylinder is fixedly installed at the upper end of the top plate, one end of the piston rod of the second hydraulic cylinder passes through and extends to the lower part of the top plate, a fixing plate is fixedly connected to one end of the piston rod of the second hydraulic cylinder, and a cutting blade is fixedly connected to the lower end of the fixing plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, after the cutting is completed, the first hydraulic cylinder drives the lifting cover to descend via the unloading mechanism. The friction wheel is exposed and rotates at high speed under the drive of the servo motor. With the help of friction, the cardboard is quickly pushed to the discharge inclined plate, and the cardboard slides down to the collection area. The whole process does not require manual intervention and the equipment does not need to stop and wait, which greatly improves the continuity of cutting and increases production efficiency. In addition, with the fixed-distance cutting mechanism, the operator only needs to accurately adjust the position of the baffle according to the required cardboard length before the first cut.

[0029] Example

[0030] like Figure 1-5 As shown, this utility model provides a technical solution: a cutting device for notebook computer packaging production, including a cutting table 1, which provides a solid foundation support for the entire cutting process. A material unloading mechanism is provided above the cutting table 1. The main function of this mechanism is to achieve automated unloading after the cardboard is cut, thereby improving production efficiency. The material unloading mechanism includes a mounting block 2, which is fixedly fixed to the upper end of the cutting table 1 by welding or bolting to ensure the reliability of the structure.

[0031] The upper end of the mounting block 2 is provided with a mounting groove 21. One side of the inner wall of the mounting groove 21 is rotatably connected to symmetrically distributed rotating rods 22 via high-precision bearings. The rotating rods 22 are made of high-strength, low-friction metal material to ensure the flexibility and stability of rotation. The outside of the rotating rods 22 is fixedly sleeved with friction wheels 23 arranged in a linear array via interference fit. The friction wheels 23 are made of high-friction rubber or special composite materials, which can effectively increase the friction with the cardboard and facilitate the movement of the cardboard. One end of one of the rotating rods 22 is rotatably connected to a support block 24 via a bearing. The lower end of the support block 24 is fixed to the inner bottom wall of the mounting groove 21 by welding or bolts, providing additional support for the rotating rod 22 and preventing it from shaking during rotation.

[0032] Above the cutting table 1 is a fixed-distance cutting mechanism, which is located above the unloading mechanism. It is mainly used to precisely control the cutting length of the cardboard and ensure that the length of the cardboard cut each time meets the production requirements.

[0033] A servo motor 25 is bolted to the inner bottom wall of the mounting slot 21 via a mounting base. The servo motor 25 features high precision, high torque, and fast response, providing stable and reliable power for the rotation of the rotating rod 22. The output shaft of the servo motor 25 is fixedly connected to one end of another rotating rod 22 via a coupling. The coupling can effectively transmit torque and compensate for installation errors between the rotating rod 22 and the output shaft of the servo motor 25, ensuring smooth power transmission. A first hydraulic cylinder 26 is symmetrically distributed and fixed to the inner bottom wall of the mounting slot 21 via welding or bolts. The first hydraulic cylinder 26 uses high-performance, well-sealed hydraulic components, enabling precise linear motion control.

[0034] One end of each piston rod of the two first hydraulic cylinders 26 is fixedly connected to a lifting cover 27 by welding or bolting. The inner wall of the lifting cover 27 is movably sleeved with the outer wall of the mounting block 2, and the two are fitted with a clearance to ensure that the lifting cover 27 can be smoothly raised and lowered along the outer wall of the mounting block 2 under the drive of the first hydraulic cylinders 26. The front of the lifting cover 27 is provided with a scale groove, which is made by high-precision laser engraving or machining process. The scale is clear and accurate, which is used to assist the operator in accurately adjusting the cutting length.

[0035] The upper end of the lifting cover 27 is provided with through slots 28 arranged in a linear array. The size and position of the through slots 28 match the friction wheel 23. When the lifting cover 27 descends, the friction wheel 23 can be exposed through the through slots 28 and contact the cardboard. The back of the lifting cover 27 is fixedly connected to the discharge ramp 29 by welding or bolts. The discharge ramp 29 is made of smooth metal plate and the surface is polished to reduce the friction when the cardboard slides down, ensuring that the cardboard can slide smoothly into the collection area. The rotating rod 22 is fixedly sleeved with a synchronous wheel 210. Both synchronous wheels 210 are connected to a synchronous belt 211. The synchronous wheels 210 and the synchronous belt 211 play the role of cooperating with the two rotating rods 22 to rotate synchronously.

[0036] The fixed-distance cutting mechanism includes a top plate 3. The lower end of the top plate 3 is fixedly connected by welding or bolts to a support rod 31 distributed in a rectangular array. The lower ends of the multiple support rods 31 are fixedly connected to the upper end of the cutting table 1 by welding or bolts, forming a stable frame structure to provide support for other components of the fixed-distance cutting mechanism.

[0037] The lower end of the top plate 3 is fixedly installed with symmetrically distributed servo electric cylinders 32 by bolts. The servo electric cylinders 32 have the characteristics of high precision and good repeatability, and can accurately control the position of the baffle 34. One end of the movable rod of the servo electric cylinder 32 is fixedly connected to a moving plate 33 by welding or bolts. The lower ends of the two moving plates 33 are fixedly connected to the baffle 34 by welding or bolts. The lower end of the baffle 34 contacts the upper end of the lifting cover 27 and is used to determine the cutting length of the cardboard.

[0038] A second hydraulic cylinder 35 is fixedly installed on the upper end of the top plate 3 by bolts. The second hydraulic cylinder 35 uses a high-performance, high-thrust hydraulic component, which can provide sufficient force to drive the cutting blade 37 to perform the cutting operation. One end of the piston rod of the second hydraulic cylinder 35 passes through and extends to the lower part of the top plate 3, and is fixedly connected to a fixing plate 36 by welding or bolts. The lower end of the fixing plate 36 is fixedly connected to the cutting blade 37 by welding or bolts. The cutting blade 37 is made of high-hardness, sharp blade material, which can cut the cardboard quickly and accurately.

[0039] The two sides of the fixed plate 36 are symmetrically connected to connecting blocks 38 by welding or bolts. The inner wall of the connecting block 38 is slidably fitted with a guide rod 39. The upper end of the guide rod 39 passes through and extends to the top plate 3. It is limited by nuts or other fixing methods to ensure that the guide rod 39 will not disengage during the up and down sliding process. The lower end of the guide rod 39 is connected to a pressure plate 310 by welding or bolts. The upper end of the pressure plate 310 is connected to a return spring 311 by welding or bolts. One end of the return spring 311 is connected to the lower end of the connecting block 38 by welding or bolts. The return spring 311 can provide a buffer when the pressure plate 310 contacts the cardboard. At the same time, when the cutting blade 37 rises and resets, it can make the pressure plate 310 quickly return to the initial position.

[0040] The working process of this utility model:

[0041] Step 1: Before powering on, the operator observes the scale groove according to the cardboard length required by the laptop packaging box design. The servo electric cylinder 32 precisely drives the moving plate 33, causing the baffle 34 to move horizontally below the top plate 3. The position of the baffle 34 is adjusted until the preset cutting length is reached, completing the initial length positioning. Subsequent cutting of the same specification does not require further adjustment. Simultaneously, the status of each component is checked to ensure that there are no foreign objects obstructing the friction wheel 23, cutting blade 37, etc., and that the power sources, such as the first hydraulic cylinder 26 and servo motor 25, are functioning properly and ready. Once ready, the long strip of cardboard is smoothly pushed from one end of the cutting table 1 to the baffle 34. At this point, the front end of the cardboard is pressed tightly against the baffle 34, awaiting cutting.

[0042] Step two: Upon receiving the command, the second hydraulic cylinder 35 starts, and the piston rod extends, pushing the fixed plate 36 and the cutting blade 37 below to move vertically downwards rapidly. Simultaneously, the pressure plate 310 descends synchronously with the fixed plate 36, contacting the cardboard before the cutting blade 37. With the buffer assistance of the return spring 311, the cardboard is firmly pressed against the upper surface of the lifting cover 27, preventing the cardboard from shaking during cutting. The cutting blade 37 continues to descend, cutting the cardboard with its sharp edge. Throughout the process, the guide rod 39 ensures the vertical and stable movement of the cutting blade 37, guaranteeing cutting accuracy.

[0043] Step 3: After cutting, the piston rod of the second hydraulic cylinder 35 retracts, driving the cutting blade 37 to rise and reset. Immediately afterwards, the first hydraulic cylinder 26 starts, the piston rod retracts, and the lifting cover 27 slides down the outer wall of the mounting block 2. The friction wheel 23 protrudes from the through groove 28 and contacts the lower surface of the cut cardboard. At this time, the servo motor 25 starts, and the output shaft drives the rotating rod 22 to rotate. The friction wheel 23 fixed on the rotating rod 22 rotates at high speed, pushing the cardboard towards the discharge ramp 29 by friction. The cardboard slides down the inclined angle of the discharge ramp 29 to the designated collection area, completing the unloading. After unloading, the piston rod of the first hydraulic cylinder 26 extends, pushing the lifting cover 27 back to the initial height. The operator pushes the subsequent cardboard forward to the baffle 34 and repeats the above cutting and unloading process to achieve efficient and continuous cutting of laptop packaging cardboard.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
