Description

Technical Field

[0001] This utility model relates to the technical field of shell trimming device for notebook computer processing, specifically a shell trimming device for notebook computer processing. Background Technology

[0002] Paper notebooks are a traditional writing tool, typically consisting of paper and a hard or soft cover. They are widely used for note-taking, drawing, writing, and planning. Compared to electronic devices, paper notebooks have advantages such as not requiring charging, being portable and lightweight, and allowing for natural writing. Furthermore, different paper notebook covers usually have different shapes, and are typically cut to a fixed shape using an edge-cutting device during the manufacturing process.

[0003] Currently, in existing technologies, paper notebook covers are usually cut by pressing down a cutting head of a fixed mold with a stamping device. However, modern paper notebook covers often include pen holders and bookmarks, which gives them complex shapes. Traditional stamping and cutting methods are clearly unable to meet the needs of large-volume, fast, and flexible cutting. Therefore, it is necessary to propose a cover cutting device for notebook processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, which are limited by the complex shapes of existing paper notebook shells, making it difficult for cutting devices to produce large quantities of complex paper notebook shells quickly and flexibly, this invention proposes a shell cutting device for notebook processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a shell trimming device for notebook processing, including an operating table, a fixed frame fixedly connected to the top of the operating table, a first hydraulic cylinder provided on the top of the fixed frame, and the end of the telescopic shaft of the first hydraulic cylinder passing through the fixed frame and provided with a trimming mechanism.

[0006] The trimming mechanism includes a fixed plate, which is fixedly connected to the end of the telescopic shaft of the first hydraulic cylinder. Cutting blades are rotatably connected to both sides of the bottom of the fixed plate. Cutting molds are provided on both adjacent sides of the cutting blades. A connecting rod is rotatably connected to one side of the cutting blade. A lifting rod is rotatably connected to one end of the connecting rod. A positioning frame is provided on the outer wall of the lifting rod. A crossbar is fixedly connected to the opposite side of the positioning frame. A second hydraulic cylinder is provided in the middle of the crossbar.

[0007] Preferably, a positioning rod is fixedly connected to the top of the fixing plate, and one end of the positioning rod passes through the top of the fixing frame and is slidably connected to the fixing frame.

[0008] Preferably, the top of the fixing plate is provided with a through groove, and the connecting rod passes through the through groove and is slidably connected to the through groove.

[0009] Preferably, the positioning frame is fixedly connected to the top of the fixing plate, and one end of the lifting rod passes through the positioning frame and is slidably connected to the positioning frame.

[0010] Preferably, the second hydraulic cylinder is fixedly connected to the top of the fixed plate, and the end of the telescopic shaft of the second hydraulic cylinder is fixedly connected to the outer wall of the crossbar.

[0011] Preferably, the cutting tool has an arc surface on one side, and one end of the connecting rod is rotatably connected to the surface of the arc surface.

[0012] Preferably, a fixing sleeve is fixedly connected to the top of the fixing plate, and a rotating shaft is rotatably connected to the inner cavity of the fixing sleeve. One end of the rotating shaft is fixedly connected to the end of the cutting tool.

[0013] The advantages of this utility model are:

[0014] This invention uses four cutting molds—one on each of the two adjacent sides of a cutting blade—to cut out complex shapes for the outer casing of a paper notebook. A second hydraulic cylinder drives a lifting rod that slides upwards, which in turn rotates the cutting blade via a connecting rod. This allows the cutting blade to rotate and change the cutting molds, enabling the cutting molds to cut different shapes for the notebook casing. This achieves the ability to quickly and flexibly cut out complex notebook casing shapes, solving the problem that existing cutting devices cannot meet the requirement of large-volume, rapid, and flexible cutting of complex paper notebook casings due to their complexity.

Detailed Implementation

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a casing trimming device for notebook computer processing. (Refer to...) Figures 1-5 A notebook shell trimming device includes an operating table 1, a fixed frame 2 fixedly connected to the top of the operating table 1, a first hydraulic cylinder 21 set on the top of the fixed frame 2, the end of the telescopic shaft of the first hydraulic cylinder 21 passing through the fixed frame 2 and equipped with a trimming mechanism 3. By introducing a paper notebook shell onto the operating table 1, the trimming mechanism 3 is driven down by the first hydraulic cylinder 21 on the fixed frame 2 to perform a trimming. Then, after the first hydraulic cylinder 21 rises, the trimming mechanism 3 rotates to switch the cutting mold 312 and performs a second cut, so that the paper notebook shell can be quickly and flexibly cut into more complex notebook outer shapes.

[0025] The trimming mechanism 3 includes a fixed plate 31, which is fixedly connected to the end of the telescopic shaft of the first hydraulic cylinder 21. Cutting blades 32 are rotatably connected to both sides of the bottom of the fixed plate 31. Cutting molds 312 are provided on adjacent sides of each cutting blade 32. A connecting rod 33 is rotatably connected to one side of the cutting blade 32, and a lifting rod 34 is rotatably connected to one end of the connecting rod 33. A positioning frame 35 is provided on the outer wall of the lifting rod 34. A crossbar 36 is fixedly connected to the opposite side of the positioning frame 35. A second hydraulic cylinder 37 is provided in the middle of the crossbar 36. The fixed plate 31 is driven to press down by the first hydraulic cylinder 21, and the fixed plate 31 slides downward stably in conjunction with the positioning rod 22. The cutting blade 32 and the cutting mold 312 are pressed down to perform the first edge cutting. Then, the first hydraulic cylinder 21 drives the fixed plate 31 to rise. At this time, the second hydraulic cylinder 37 drives the crossbar 36 to rise. The rise of the crossbar 36 drives the lifting rod 34 to rise. The lifting rod 34 drives the cutting blade 32 to rotate and switch the cutting mold 312. After the cutting mold 312 is switched, the first hydraulic cylinder 21 drives the fixed plate 31 to press down again to cut. In specific implementation, different cutting molds 312 can be set on the adjacent sides of the cutting blade 32 according to actual needs, so that different shapes of paper notebook shells can be cut quickly and flexibly.

[0026] Reference Figure 1 , Figure 2 and Figure 3 A positioning rod 22 is fixedly connected to the top of the fixed plate 31. The positioning rod 22 passes through the top of one end of the fixed frame 2 and is slidably connected to the fixed frame 2. The positioning frame 35 is fixedly connected to the top of the fixed plate 31. One end of the lifting rod 34 passes through the positioning frame 35 and is slidably connected to the positioning frame 35. The second hydraulic cylinder 37 is fixedly connected to the top of the fixed plate 31. The end of the telescopic shaft of the second hydraulic cylinder 37 is fixedly connected to the outer wall of the crossbar 36. The crossbar 36 is driven to rise by the second hydraulic cylinder 37. The crossbar 36 drives the lifting rod 34 to slide upward on the positioning frame 35. The lifting rod 34 drives the cutting tool 32 to rotate through the connecting rod 33. The cutting tool 32 rotates and switches the cutting mold 312, thereby achieving the purpose of rotating and switching the cutting mold 312.

[0027] Reference Figure 3 , Figure 4 and Figure 5The top of the fixed plate 31 has a through groove 311, and the connecting rod 33 passes through the through groove 311 and is slidably connected to the through groove 311. The cutting tool 32 has an arc surface 38 on one side, and one end of the connecting rod 33 is rotatably connected to the surface of the arc surface 38. The top of the fixed plate 31 is fixedly connected to the fixed sleeve 39, and the inner cavity of the fixed sleeve 39 is rotatably connected to the rotating shaft 310. One end of the rotating shaft 310 is fixedly connected to the end of the cutting tool 32. The second hydraulic cylinder 37 drives the crossbar 36 to rise, the crossbar 36 drives the lifting rod 34 to rise, the lifting rod 34 drives the connecting rod 33 to move upward and rotate, and the connecting rod 33 moves stably in conjunction with the through groove 311. One end of the connecting rod 33 pulls the arc surface 38 of the cutting tool 32, so that the cutting tool 32 rotates in conjunction with the fixed sleeve 39 and the rotating shaft 310, thereby enabling the cutting tool 32 to rotate stably to switch the cutting mold 312.

[0028] Working principle: In use, the notebook casing is introduced into the operating table 1. The first hydraulic cylinder 21 on the fixed frame 2 drives the cutting mechanism 3 to perform the first cut. The first hydraulic cylinder 21 drives the fixed plate 31 to press down. The fixed plate 31 and the positioning rod 22 cooperate to press down stably. The fixed plate 31 drives the cutting tool 32 to cooperate with the cutting mold 312 to perform a first cut. Then, the first hydraulic cylinder 21 drives the fixed plate 31 to rise, and the second hydraulic cylinder 37 drives the crossbar 36 to rise. The crossbar 36 drives the lifting rod 34 to rise. The lifting rod 34 slides stably upward on the positioning frame 35. The lifting rod 34 pulls the arc surface 38 of the cutting tool 32 to rotate through the connecting rod 33. The connecting rod 33 cooperates with the through groove 311 to move stably. The cutting tool 32 cooperates with the fixed sleeve 39 and the rotating shaft 310 to rotate stably. The rotation of the cutting tool 32 causes the cutting mold 312 on the other side to move downward. The first hydraulic cylinder 21 drives the fixed plate 31 to press down again to perform a second cut, thereby achieving the goal of quickly and flexibly cutting out relatively complex shapes of paper notebook casings.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
