DETAILED DESCRIPTION

[0049] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0050] To simplify the drawings, only the parts relevant to the utility model are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0051] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0052] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0053] Reference Figures 1 to 8, which is the first embodiment of the utility model, proposes a cutting tool, including: a placement table 1, having a mounting groove 104; a first tool 2, arranged in the mounting groove 104; a second tool 3, rotatably set on the placement table 1; an adjusting member 4, set on the placement table 1, one side of the first tool 2 abuts against the adjusting member 4, and the adjusting member 4 is used to drive the first tool 2 to approach or move away from the second tool 3.

[0054] The above solution aims to address the complex and inefficient cutting distance adjustment issues encountered in the prior art. This cutting tool makes the cutting process more flexible and efficient. A long, rectangular mounting slot 104 is provided on the top of the placement table 1, precisely and securely securing the first cutting tool 2. The first cutting tool 2 is a fixed tool, its sides smoothly and precisely fitting onto the adjustment member 4. The second cutting tool 3 is a rotating tool, mounted on the placement table 1 via precision bearings, enabling smooth rotation and improving cutting accuracy and speed. The adjustment member 4 is mounted on the placement table 1 and connected to the first cutting tool 2 via a precision threaded mechanism. The operator simply controls the adjustment member 4 to precisely move the first cutting tool 2 closer to or further away from the second cutting tool 3 along the mounting slot 104, achieving quick and accurate cutting distance adjustment. Operational Flow: To use, first adjust the position of the first cutting tool 2 according to the workpiece requirements. After turning on the device, the second cutting tool 3 rotates, driving the workpiece between the two cutting tools for precise cutting. To adjust the cutting thickness, simply adjust the first cutting tool 2 using the adjustment member 4, eliminating the need for tool replacement or complex calibration. The cutting tool of this embodiment simplifies the adjustment process of the cutting distance and improves the flexibility and efficiency of the cutting operation.

[0055] Furthermore, the placement table 1 includes: a mounting seat 101, a mounting groove 104 is arranged on the mounting seat 101; a plurality of mounting plates 102, the mounting plates 102 are symmetrically arranged at the two ends of the mounting seat 101, and the second tool 3 is rotatably set on the mounting plate 102, and the second tool 3 is located above the first tool 2.

[0056] In the above scheme, the mounting groove 104 is provided at the top of the mounting base 101 so that the first tool 2 can be firmly installed and slide smoothly along the inclined surface of the mounting groove 104. In order to balance the torque generated when the second tool 3 rotates, two mounting plates 102 are symmetrically provided at both ends of the mounting base 101 in this embodiment to ensure that the second tool 3 can remain stable even under high-speed rotation. The second tool 3 is located above the first tool 2, and when the two are opposite to each other, cutting can be achieved. When in use, the user first installs the first tool 2 in the mounting groove 104 according to the required position, and accurately adjusts it to the predetermined cutting thickness through the adjustment member 4. Subsequently, the drive motor of the second tool 3 is started, and the second tool 3 begins to rotate smoothly. The workpiece is fed between the two tools through a manual or automatic feeding device. Since the second tool 3 is located directly above the first tool 2, and the high stability of the entire system, fast and precise cutting operations can be achieved, and extremely high cutting quality can be guaranteed even for thin sheet materials.

[0057] Furthermore, the adjusting member 4 includes: a lifting screw 401, which is rotatably set on the mounting seat 101, and one side of the first tool 2 abuts against the end of the lifting screw 401, and the lifting screw 401 is used to push the first tool 2 closer to or away from the second tool 3; a fastening bolt 402, which is slidably set on the mounting seat 101, and the first tool 2 is set on the fastening bolt 402. After the first tool 2 moves, the fastening bolt 402 is used to fix the first tool 2.

[0058] In the above embodiment, the end of the lifting screw 401 is designed with a smooth pressing surface that contacts a side surface of the first cutter 2. When the operator rotates the lifting screw 401, it moves upward or downward along its axis, directly pushing the first cutter 2 toward or away from the second cutter 3 located above. This simplifies the cutting distance adjustment process, allowing quick adjustments with a single hand while maintaining precise adjustments. To ensure the stable fixation of the first cutter 2 after adjustment, this embodiment introduces a sliding fastening bolt 402. The first cutter 2 is mounted on the fastening bolt 402 via a fixing clamp or threaded interface. Once the position is adjusted using the lifting screw 401, the operator can securely lock the first cutter 2 in its new position by tightening the nut or using a tool such as a wrench. This not only ensures absolute stability of the cutter during cutting but also facilitates subsequent readjustment. In practice, the user first loosens the fastening bolt 402, then rotates the lifting screw 401 to adjust the vertical position of the first cutter 2 until the desired cutting thickness is achieved. Using the scale markings or electronic display beside the mounting slot 104 to assist with positioning, quick and accurate adjustment is achieved. Then, simply slide the fastening bolt 402 to the desired position and tighten it, completing the adjustment process. This design not only simplifies the operation process but also significantly reduces preparation time and improves production efficiency.

[0059] Furthermore, the mounting seat 101 includes: a seat body 1011; a first limiting portion 1012, which is arranged on the seat body 1011, the first limiting portion 1012 has a first threaded hole 1014, and the lifting screw 401 is threadedly connected to the first threaded hole 1014; a second limiting portion 1013, which is arranged on the seat body 1011, the second limiting portion 1013 has an adjustment hole 1015, the fastening bolt 402 passes through and is slidably arranged in the adjustment hole 1015, and the end of the fastening bolt 402 away from the adjustment hole 1015 is arranged on the first tool 2; a mounting groove 104 is formed between the first limiting portion 1012 and the second limiting portion 1013.

[0060] In the above scheme, the first limiting portion 1012 is arranged on one side of the top of the base 1011, and a first threaded hole 1014 is provided on it, which is specifically used to receive the lifting screw 401. The design of the first threaded hole 1014 ensures the smooth rotation and precise axial movement of the lifting screw 401, thereby realizing fine adjustment of the upper and lower positions of the first tool 2. The lifting screw 401 is tightly coupled with the first threaded hole 1014 through a thread, and is both stable and has sufficient torque transmission capacity when rotating. The second limiting portion 1013 is arranged on the other side of the base 1011, adjacent to the first limiting portion 1012, forming the boundary of the mounting groove 104. The second limiting portion 1013 is provided with an adjustment hole 1015, which allows the fastening bolt 402 to slide freely, facilitating the position adjustment of the first tool 2. One end of the fastening bolt 402 is assembled on the first tool 2, and the other end passes through the adjustment hole 1015 and is used to fix the position of the first tool 2 after the adjustment is completed, to prevent position displacement due to vibration and other reasons. The mounting groove 104 formed between the first limiting portion 1012 and the second limiting portion 1013 provides a stable mounting platform for the first tool 2. The size and shape of the mounting groove 104 are customized according to the specific specifications of the first tool 2 to ensure that the tool can fit tightly and is easy to adjust. During the operation, first, the first tool 2 is installed on the fastening bolt 402, and the fastening bolt 402 is inserted into the adjustment hole 1015. At this time, the position of the first tool 2 can be preliminarily adjusted by sliding the fastening bolt 402 back and forth. Then, the lifting screw 401 is screwed into the first threaded hole 1014. By rotating the lifting screw 401, the up and down movement of the first tool 2 can be precisely controlled to achieve fine-tuning of the cutting thickness. During the adjustment process, the measurement mark or electronic sensor next to the mounting groove 104 can be used to assist in determining the position. Once the ideal position is reached, the first tool 2 is fixed by the locking mechanism of the fastening bolt 402 to prevent displacement during operation.

[0061] Furthermore, the first tool 2 includes: a first tool holder 201, which is rectangular, the first tool 2 has a second threaded hole 203, the second threaded hole 203 is connected to the adjustment hole 1015, and the fastening bolt 402 passes through the adjustment hole 1015 and is threadedly connected to the second threaded hole 203; there are several first tool heads 202, and each first tool head 202 is respectively arranged at the corners of the first tool holder 201.

[0062] In the above solution, the first cutter holder 201 is designed in a rectangular shape to increase its stability on the mounting base 101. This rectangular structure not only facilitates even distribution of cutting pressure but also ensures stability during adjustment. A second threaded hole 203 is formed in the first cutter holder 201, which corresponds to and communicates with the adjustment hole 1015 in the mounting base 101. After passing through the adjustment hole 1015, the fastening bolt 402 can be directly threaded into the second threaded hole 203 in the first cutter holder 201, achieving a more secure fixation and preventing displacement even under high cutting forces. The first cutter 2 is not a single blade, but rather a combination of multiple first cutter heads 202. Each first cutter head 202 is positioned at a corner of the first cutter holder 201, facilitating replacement of different first cutter heads 202. Each cutter head can be made of different materials and shapes based on specific cutting requirements, such as carbide for enhanced wear resistance or designed with a specific angle to accommodate specific cutting angles. In actual operation, the first tool 2 is first connected to the second threaded hole 203 of the first tool holder 201 through the fastening bolt 402 through the adjustment hole 1015, and then the first tool 2 is fine-tuned up and down using the lifting screw 401 until the ideal cutting depth is reached, and then the fastening bolt 402 is rotated for preliminary positioning.

[0063] Furthermore, the sliding direction of the fastening bolt 402 along the adjustment hole 1015 is the same as the axial direction of the first threaded hole 1014 .

[0064] In the above embodiment, the fastening bolt 402 not only slides through the adjustment hole 1015 to adjust the position of the first cutter 2, but also its sliding direction is aligned with the axis of the first threaded hole 1014. When the operator adjusts the vertical position of the first cutter 2 using the jacking screw 401 (i.e., by rotating the jacking screw 401 to move it up and down in the first threaded hole 1014), the sliding path of the fastening bolt 402 is parallel to the moving direction of the jacking screw 401.

[0065] Furthermore, the mounting plate 102 has an assembly groove and also includes: a rotating shaft 5, which is rotatably arranged in the assembly groove of the mounting plate 102; a connecting seat 6, which is arranged at the end of the rotating shaft 5, and the connecting seat 6 has a card slot 601, and the second tool 3 is arranged in the card slot 601.

[0066] In the above scheme, the mounting plate 102, in addition to being symmetrically positioned at both ends of the placement platform 1 to support the second cutting tool 3, also features assembly slots. These assembly slots, machined into the top of the mounting plate 102, ensure that the rotating shaft 5 is securely mounted and rotates freely, while also reducing unnecessary vibration and wear. One end of the rotating shaft 5 is tightly connected to the mounting plate 102 via a bearing structure, while the other end extends outside the mounting plate 102 and connects to the connecting base 6. This allows the rotating shaft 5 to not only support the weight of the second cutting tool 3 but also maintain dynamic balance under high-speed rotation. The connecting base 6, mounted at the end of the rotating shaft 5, features a slot 601. The second cutting tool 3 fits within the slot 601. In practice, to replace or maintain the second cutting tool 3, the operator simply loosens the fasteners on the connecting base 6 to easily remove the second cutting tool 3 from the slot 601 for inspection or replacement. Once completed, the second cutting tool 3 is reinserted into the slot 601 and the fasteners are tightened to ensure stability. The assembly groove design of the rotating shaft 5 and the mounting plate 102 ensures that the entire replacement process is simple and quick, reduces maintenance costs, and improves production efficiency.

[0067] Furthermore, the second tool 3 includes: a second tool holder 301, which is cylindrical, and the end of the second tool holder 301 is clamped in the clamping groove 601; a second tool head, which is arranged on the second tool holder 301; and a convex strip, which is arranged on the second tool holder 301 and is located on the side away from the second tool head.

[0068] In the above solution, the second blade holder 301 is designed as a cylinder. This shape not only helps evenly distribute the centrifugal force during rotation, but also ensures that the second blade holder 301 is firmly embedded in the slot 601 of the connecting seat 6, preventing loosening even at high speeds, thereby improving overall stability and safety. The second blade is directly mounted on the second blade holder 301 to ensure its sharpness and durability. The raised strip can be equipped with a rubber strip to facilitate feeding during rotation.

[0069] Furthermore, a receiving groove 103 is provided on the top of the seat body 1011 . The receiving groove 103 is located between the first limiting portion 1012 and the second limiting portion 1013 . The receiving groove 103 is used to receive the first cutting head 202 away from the rotating shaft 5 .

[0070] In the above solution, the receiving groove 103 is a U-shaped groove, and the non-working first cutting head 202 can be placed in the receiving groove 103 to prevent the first cutting head 202 from causing harm to the operator.

[0071] Furthermore, the assembly further includes an insert block 7 detachably disposed within the slot 601. Once inserted into the slot 601, the insert block 7 is used to compress the end of the second blade holder 301. The insert block 7 is used to seal the slot 601. Once the ends of the second blade holder 301 are mounted in the slot 601, they can be secured to the insert block 7. It should be noted that the insert block 7 is secured to the connecting base 6 via bolts.

[0072] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
