[0035] 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.

[0036] 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."

[0037] 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.

[0038] 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.

[0039] Reference Figures 1 to 3 , which is an embodiment of the utility model, proposes a knife ring extension adjustment device for an automatic knife sharpener, including: a base 1; a mounting plate 2, slidably arranged on the base 1; an adjusting member 3, arranged on the mounting plate 2; a top knife member 5, arranged on the mounting plate 2; a top wear-resistant plate 4, arranged on the adjusting member 3, the adjusting member 3 is used to adjust the distance between the top wear-resistant plate 4 and the top knife member 5, and the distance between the top knife member 5 and the top wear-resistant plate 4 is the knife extension amount.

[0040] In the above scheme, the knife ring extension adjustment device for an automatic knife sharpener of the present invention is mainly composed of a base 1, a mounting plate 2, an adjusting member 3, a top knife member 5 and a top wear-resistant plate 4. The base 1 serves as the basic supporting structure of the entire device and has sufficient stability and strength. The mounting plate 2 is slidably arranged on the base 1 and can move smoothly within a certain range. The adjusting member 3 is arranged on the mounting plate 2, and the screw is driven by the servo motor 6, thereby pushing the wedge-shaped slider to move, thereby adjusting the distance between the top wear-resistant plate 4 and the top knife member 5. This distance is the knife extension amount, and the operator can accurately adjust the knife extension amount according to actual needs to meet different processing requirements. The top knife member 5 is also arranged on the mounting plate 2, and cooperates with the top wear-resistant plate 4. The top wear-resistant plate 4 is arranged on the adjusting member 3 and changes its position as the adjusting member 3 moves.

[0041] Adjusting the tool extension: The servo motor 6 precisely controls the rotation of the screw, driving the wedge-shaped slider to move, changing the distance between the top wear-resistant plate 4 and the top cutter 5, thereby adjusting the tool extension. The operator can use the control system to set the appropriate tool extension according to specific processing requirements, improving processing accuracy and efficiency.

[0042] Monitoring Blade Extension: When the blade extends and presses against the top cutter element 5, the top cutter element 5 mounting bracket 502 abuts against the limit detection bolt, achieving a closed state with gap B of 0. The limit detection bolt is hollow. When the blade is pressed firmly against the top cutter element 5, the compressed air pressure inside it rises to a value close to the source pressure. By monitoring this pressure change, accurate determination of blade extension is made, ensuring the stability and safety of the machining process.

[0043] Measuring the Knife Ring Radius: After adjusting the knife extension, extend the displacement monitoring cylinder 8 to push the top wear plate 4 against the knife wear plate. The value detected by the displacement monitoring cylinder 8 is then added to the value from the zero cylinder position to the knife ring center point to calculate the knife ring radius. This function conveniently measures the knife ring dimensions, providing a basis for adjusting parameters during the machining process.

[0044] Beneficial effects: There is no need to manually disassemble the knife ring for grinding and adjusting the knife, which greatly saves time and labor costs. Through the automated adjustment device, parameters such as the knife extension amount can be adjusted quickly and accurately, thereby improving production efficiency. Accurate control of processing parameters: The use of components such as the servo motor 6 and the displacement monitoring cylinder 8 enables parameters such as the knife extension amount and the knife ring radius to be precisely controlled, thereby improving processing accuracy and quality. Real-time monitoring function: It can monitor in real time whether the blade is ejected into place, as well as parameters such as the radius of the knife ring, providing reliable protection for the processing process and reducing processing failures and scrap rates caused by inaccurate parameters. In summary, the knife ring extension amount adjustment device for the automatic knife sharpener of the utility model has the advantages of reasonable structure, powerful functions, and easy operation. It can effectively solve the problems existing in the prior art and provide strong support for the efficient operation of the ring-type flaking machine.

[0045] Furthermore, the adjusting member 3 includes: a first plate 302, located on one side of the mounting plate 2, the first plate having a fixed plate on the side away from the second plate, the fixed plate being arranged on the first plate, and the top wear-resistant plate 4 being arranged on the fixed plate; a second plate 301, arranged on the mounting plate 2, a sliding space 304 being provided between the first plate 302 and the second plate 301, the second plate 301 having a first inclined surface 3011; a wedge-shaped slider 303, one side of the wedge-shaped slider 303 being slidingly provided on the first plate 302, and the other side of the wedge-shaped slider 303 being slidingly provided on the second plate 301, and the wedge-shaped slider 303 being located in the sliding space 304, the wedge-shaped slider 303 having a second inclined surface 3012, the first inclined surface 3011 and the second inclined surface 3012 being slidingly fitted together, and after the wedge-shaped slider 303 slides, the first plate 302 approaches or moves away from the second inclined surface 3012.

[0046] In the above scheme, when the distance between the top wear-resistant plate 4 and the top blade 5 (i.e., the amount of blade extension) needs to be adjusted, the wedge-shaped slider 303 is caused to slide within the sliding space 304 by an external drive (e.g., a servo motor 6 driving a screw). Because the two side surfaces of the wedge-shaped slider 303 are in sliding contact with the first plate 302 and the second plate 301, respectively, and the second inclined surface 3012 of the wedge-shaped slider 303 is in sliding contact with the first inclined surface 3011 of the second plate 301, when the wedge-shaped slider 303 slides, the interaction of the inclined surfaces causes the first plate 302 to move closer to or further away from the second plate 301. If the wedge-shaped slider 303 slides in a certain direction, causing the first plate 302 to move away from the second plate 301, the distance between the top wear-resistant plate 4 and the top blade 5 increases; otherwise, the distance decreases.

[0047] The structural design of this adjustment member 3 has the following beneficial effects: first, through the inclined structure of the wedge-shaped slider 303, the external linear driving force can be converted into the vertical movement of the first plate 302, thereby realizing precise adjustment of the knife extension amount; second, the structure is compact and occupies little space, and can realize efficient adjustment function within a limited installation space; third, the sliding fit method makes the adjustment process smooth and reliable, without jamming or jumping, thereby ensuring the accuracy and stability of the adjustment.

[0048] To sum up, the adjusting member 3 is composed of a first plate 302, a second plate 301 and a wedge-shaped slider 303. Through the sliding of the wedge-shaped slider 303 in the sliding space 304 and the interaction of the inclined surfaces, the precise adjustment of the distance between the top wear-resistant plate 4 and the top knife member 5 is achieved, and it has the advantages of compact structure, precise adjustment, stability and reliability.

[0049] Furthermore, the wedge-shaped slider 303 has a threaded hole therein and also includes: a screw 11, which is threadedly connected to the threaded hole; a servo motor 6, which is arranged on the mounting plate 2, and one end of the screw 11 is arranged on the servo motor 6, and the servo motor 6 is used to drive the wedge-shaped slider 303 to slide along the sliding space 304.

[0050] In the above-described scheme, the wedge-shaped slider 303 of the knife ring blade extension adjustment device has a threaded hole inside. It also includes a leadscrew 11 and a servo motor 6. The leadscrew 11 is threadedly connected to the threaded hole of the wedge-shaped slider 303. The servo motor 6 is mounted on the mounting plate 2, with one end of the leadscrew 11 connected to the servo motor 6. When the servo motor 6 is in operation, it drives the leadscrew 11 to rotate. Because the leadscrew 11 is threadedly connected to the wedge-shaped slider 303, the rotation of the leadscrew 11 is converted into linear motion of the wedge-shaped slider 303 within the threaded hole. Since the wedge-shaped slider 303 is located within the sliding space 304 formed by the first plate 302 and the second plate 301, the servo motor 6 ultimately drives the wedge-shaped slider 303 to slide along the sliding space 304. Precise control of the servo motor 6 allows for high-precision adjustment of the sliding motion of the wedge-shaped slider 303, thereby accurately controlling the distance between the top wear-resistant plate 4 and the top cutter 5, i.e., the blade extension. The servo motor 6 provides stable power output, ensuring the reliability and accuracy of the adjustment process. On the other hand, the threaded connection method has high transmission efficiency, which can effectively convert the rotational motion of the servo motor 6 into the linear motion of the wedge slider 303, and can realize the self-locking function to prevent the wedge slider 303 from accidentally moving during operation, thereby ensuring the stability of the device.

[0051] Furthermore, it also includes: a limit monitoring bolt 7, which is arranged on the mounting plate 2, and the top blade 5 has a contact end 701, which can abut against the limit monitoring bolt 7, the limit monitoring bolt 7 is a hollow structure, and the limit monitoring bolt 7 is externally connected to a compressed air component.

[0052] In the above scheme, a limit monitoring bolt 7 is also provided in the knife ring extension adjustment device, which is arranged on the mounting plate 2. The top knife member 5 has a contact end 701, and under certain circumstances, this contact end 701 can abut against the limit monitoring bolt 7. The limit monitoring bolt 7 is a hollow structure and is externally connected to a compressed air component. When the blade is extended to press against the top knife member 5, the contact end 701 of the top knife member 5 will stick to the limit monitoring bolt 7. Since the limit monitoring bolt 7 is a hollow structure, when the contact end 701 is pressed against the limit monitoring bolt 7 and the gap is zero, the compressed air pressure value here will rise to close to the air source pressure. By monitoring the change of this pressure value, it can be accurately judged whether the blade is extended into place. This method provides a real-time monitoring function to ensure stability and safety. At the same time, the hollow structure of the limit monitoring bolt 7 cooperates with the external compressed air component to form an effective monitoring system, which improves the intelligence and reliability of the device.

[0053] Furthermore, the top blade member 5 includes a C-shaped fixing frame 502, one end of which is hinged to the mounting plate 2, and the other end of which is a contact end 701. A top blade block 501 is disposed on the fixing frame 502 and is located on a side away from the mounting plate 2.

[0054] In the above scheme, the top cutter member 5 is composed of a fixing frame 502 and a top cutter block 501. The fixing frame 502 is C-shaped, and one end is hinged to the mounting plate 2, so that the fixing frame 502 can move within a certain range. The other end of the fixing frame 502 is a contact end 701, which is used to contact the limit monitoring bolt 7. The top cutter block 501 is arranged on the fixing frame 502 and is located on the side away from the mounting plate 2. During operation, when the blade is extended, it will press the top cutter block 501, thereby causing the fixing frame 502 to move accordingly. The C-shaped fixing frame 502 not only ensures the stable installation of the top cutter block 501, but also provides a suitable space and angle for its contact with the blade. At the same time, the hinged connection method enables the fixing frame 502 to flexibly respond to the tightening force of the blade, thereby improving the adaptability and reliability of the device.

[0055] Furthermore, it also includes: a displacement monitoring cylinder 8, which is arranged on the base 1, and the movable end of the displacement monitoring cylinder 8 is hinged to the other side of the mounting plate 2.

[0056] In the above scheme, the displacement monitoring function: The primary function of the displacement monitoring cylinder 8 is to monitor the displacement of the mounting plate 2. In the knife ring extension adjustment device, the displacement of the mounting plate 2 is directly related to the distance between the top wear-resistant plate 4 and the top blade 5, i.e., the blade extension. By monitoring the displacement of the mounting plate 2, the blade extension can be accurately determined, providing data support for precise adjustment. The cylinder can provide real-time feedback on the displacement of the mounting plate 2 through internal sensors or measuring devices, allowing the operator to promptly understand changes in blade extension and make adjustments as needed.

[0057] The displacement monitoring cylinder 8 can not only monitor the displacement, but also assist in adjusting the amount of knife extension to a certain extent. For example, in the process of adjusting the amount of knife extension, the position of the mounting plate 2 can be fine-tuned by controlling the extension and contraction of the displacement monitoring cylinder 8, thereby more accurately controlling the distance between the top wear-resistant plate 4 and the top knife piece 5. The displacement monitoring cylinder 8 hinged to the mounting plate 2 can provide a certain amount of support for the mounting plate 2 during operation, thereby improving the stability of the mounting plate 2. In particular, when the knife ring is working, it may generate large forces and vibrations. The supporting role of the displacement monitoring cylinder 8 can reduce the shaking of the mounting plate 2, ensuring the stability of the knife extension and processing accuracy.

[0058] Furthermore, it also includes: a slide rail 9, which is arranged on the base 1; a sliding plate 10, which is slidably arranged on the slide rail 9, and the mounting plate 2 is hinged to the sliding plate 10.

[0059] In the above embodiment, the knife ring extension adjustment device also includes a slide rail 9 and a slide plate 10. The slide rail 9 is mounted on the base 1, providing a stable sliding path for the slide plate 10. The slide plate 10 slides on the slide rail 9, allowing for smooth movement along the rail 9. The mounting plate 2 is hingedly connected to the slide plate 10. This connection allows the mounting plate 2 to move with the slide plate 10 while also rotating within a certain angle range, increasing the flexibility of the device. The combined structure of the slide rail 9 and the sliding plate 10 has the following important functions: First, it provides a more stable and precise guide for the movement of the mounting plate 2, ensuring that the mounting plate 2 will not deviate or shake during the sliding process, thereby ensuring the accuracy of the spacing adjustment between the top wear-resistant plate 4 and the top knife piece 5; second, the sliding of the sliding plate 10 on the slide rail 9 can assist in adjusting the knife extension amount. By controlling the position of the sliding plate 10, the position of the mounting plate 2 can be indirectly adjusted, thereby changing the spacing between the top wear-resistant plate 4 and the top knife piece 5; third, this structural design improves the stability and reliability of the entire device, so that the device can withstand greater force and vibration during operation, thereby extending the service life of the device.

[0060] 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.
