Description

Technical Field

[0001] This utility model relates to the field of cutting knife technology, and in particular to a double-edged cutting knife. Background Technology

[0002] A cutting knife is a tool used to precisely cut various materials. It is usually made of sturdy and durable materials, such as high-carbon steel or stainless steel, and has a sharp blade that can easily cut a variety of materials such as paper, cloth, plastic, and metal.

[0003] Currently, most mainstream cutting tools on the market adopt a single-tail design, meaning that the blade only has a tail on one side. This results in an imbalance of weight on both sides of the blade and a shift in the center of gravity, causing uneven force on the blade during the cutting process and uneven end faces of the cut material, thus reducing the cutting quality.

[0004] Meanwhile, single-blade cutting blades are mostly equipped with only a single cutting edge, which means that when the blade wears or becomes dull after prolonged use, operators need to stop the machine to replace or sharpen it. This not only increases maintenance costs but also reduces overall production efficiency. Utility Model Content

[0005] The main purpose of this utility model is to provide a double-edged cutting knife, which aims to improve cutting quality, reduce maintenance costs, and enhance overall production efficiency.

[0006] To achieve the above objectives, this utility model proposes a double-edged cutting knife, including a blade body, on which blade tails are symmetrically arranged on both the left and right sides, and each blade tail is fixedly connected to the blade body. A first cutting edge is provided at the bottom of the blade body, and a second cutting edge is provided at the top of the blade body. The end faces of the first and second cutting edges are beveled to form a beveled blade edge.

[0007] In one possible implementation, it further includes mounting plates respectively disposed on one side of each blade tail, and one side of each blade tail is rotatably connected to the corresponding mounting plate via a pivot, wherein the mounting plate is provided with a fixing member for fixing the blade body.

[0008] In one possible implementation, the fastener includes threaded holes on both sides of the blade tail and a first bolt, the first bolt being disposed on the mounting plate and threadedly connected to the mounting plate, and one side of the first bolt being threadedly connected to the threaded hole.

[0009] In one possible implementation, a fixing plate is provided on one side of each of the blade tails, the fixing plate being fixedly connected to the blade tail by a second bolt, and the rotating shaft being fixedly connected to the fixing plate.

[0010] In one possible implementation, the mounting plate is provided with a rolling bearing, and the rotating shaft is fixedly connected to the inner ring of the rolling bearing.

[0011] In one possible implementation, the mounting plate is provided with a plurality of mounting holes.

[0012] Working principle and beneficial effects:

[0013] 1. This design ensures weight balance on both sides of the blade by symmetrically placing the blade tails, resulting in uniform gravity distribution. When the drive unit moves the blade, the force on the blade is also more even, reducing potential blade misalignment during movement. This not only guarantees the flatness of the material end face after cutting and improves cutting quality, but also avoids blade chipping caused by uneven force on the left and right blades, thus extending the blade's lifespan.

[0014] 2. This solution sets up a first cutting edge and a second cutting edge. When the first cutting edge becomes dull and worn, there is no need to disassemble or replace the tool. Simply switch to the unworn second cutting edge to continue cutting. This avoids the tedious operation of replacement or grinding, thereby reducing maintenance costs and improving overall production efficiency. Attached Figure Description

[0021] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] Example 1:

[0024] refer to Figure 1 This embodiment proposes a double-edged cutting blade, including a blade body 1. Blade tails 1011 are symmetrically arranged on both the left and right sides of the blade body 1, and each blade tail 1011 is fixedly connected to the blade body 1. By symmetrically arranging the blade tails 1011 on both sides of the blade body, the weight balance on both sides is ensured, thus ensuring that the gravity on both sides is equal. When the driving component pushes the blade body 1 to move, the force on the blade body 1 is also more uniform, reducing the possible deviation of the blade body during movement. This not only ensures the flatness of the material end face after cutting and improves the cutting quality, but also avoids the blade chipping phenomenon caused by uneven force on the left and right blades, thereby extending the service life of the blade.

[0025] Secondly, the bottom of the blade 1 is provided with a first cutting edge 101, and the top of the blade 1 is provided with a second cutting edge 102. The end faces of the first cutting edge 101 and the second cutting edge 102 are beveled to form a beveled edge. The beveled edge design of the beveled structure can optimize the force distribution during cutting, reduce local friction and impact of a single cutting edge, further slow down the wear rate of a single cutting edge, and thus improve the overall service life.

[0026] By setting a first cutting edge 101 and a second cutting edge 102, when the first cutting edge 101 becomes dull and worn, there is no need to disassemble or replace the tool. Simply switch to the unworn second cutting edge 102 to continue cutting. This avoids the tedious operation of replacement or grinding, thereby reducing maintenance costs and improving overall production efficiency.

[0027] Example 2:

[0028] Based on Example 1, and referring to Figure 2-4 This embodiment also includes mounting plates 103 respectively disposed on one side of each blade tail 1011. One side of each blade tail is rotatably connected to the corresponding mounting plate 103 via a rotating shaft 104. The mounting plate 103 is provided with a fixing member for fixing the blade body 1.

[0029] With the installation plate 103 and the fixing parts, when the first blade 101 is worn, there is no need to disassemble the tool. Just loosen the fixing parts and rotate the blade body 1 through the rotating shaft 104 to switch the unworn second blade 102 to the working position. Then fix the blade body 1 with the fixing parts to resume operation. This shortens the downtime for blade replacement and is easy to operate.

[0030] Meanwhile, the mounting plate 103 is provided with several mounting holes 109, which provide mounting positions for the cutting tools, cutting equipment, and tool holder, so that workers can install the cutting tools.

[0031] Specifically, the fasteners include threaded holes 110 on both sides of the blade tail 1011 and a first bolt 105. The first bolt 105 is mounted on the mounting plate 103 and threadedly connected to the mounting plate 103, and one side of the first bolt 105 is threadedly connected to the threaded hole 110.

[0032] When the first cutting edge 101 shows wear, the operator unscrews all the first bolts 105 on each mounting plate 103, disengaging one side of the first bolt 105 from the threaded hole 110. Then, the blade body 1 can be rotated to switch the second cutting edge 102 to the working position. Finally, a tool is used to screw the first bolts 105 on the mounting plate 103 into the threaded hole 110, thus securing the blade body 1. Connecting the first bolts 105 to the threaded hole 110 ensures the blade body 1 remains stable during high-speed cutting or impact, preventing the blade from shifting its contact position with the material due to blade body 1 shaking, and reducing unnecessary wear on the cutting edge.

[0033] Meanwhile, the disassembly and tightening of the threaded connection is simple, requiring only the rotation of the first bolt 105, which ensures both the reliability of the fixation and the ease of switching the blade.

[0034] In this embodiment, a fixing plate 106 is provided on one side of each blade tail 1011. The fixing plate 106 is fixedly connected to the blade tail 1011 by a second bolt 107, and the rotating shaft 104 is fixedly connected to the fixing plate 106.

[0035] When the rotating shaft 104 wears or is damaged due to long-term rotation, it is not necessary to replace the entire blade 1. Only the second bolt 107 needs to be removed to take off the fixing plate 106, and the rotating shaft 104 can be replaced or repaired separately. Similarly, if the blade 1 is partially damaged, the blade 1 can be replaced separately, thereby reducing the cost of replacing parts. At the same time, the bolt connection method is also convenient for installation and disassembly, improving the convenience of tool maintenance.

[0036] In addition, a rolling bearing 108 is provided on the mounting plate 103, and the rotating shaft 104 is fixedly connected to the inner ring of the rolling bearing 108. The rolling bearing 108 reduces wear between the rotating shaft 104 and the mounting plate 103, making the blade 1 rotate more smoothly and effortlessly, thereby extending the service life of both.
