Abstract
Description
Technical Field
[0001] The invention relates to the technical field of plate cutting, in particular to a gypsum board push knife. Background Art
[0002] With the rapid development of building decoration and furniture manufacturing industries, gypsum board, as a commonly used building and decoration material, has been increasingly widely used. Gypsum board has the advantages of light weight, high strength, and easy processing, but in actual applications, it needs to be cut according to specific needs to adapt to different size and shape requirements. Therefore, gypsum board cutting tools have become an indispensable equipment in the process of building decoration and furniture manufacturing.
[0003] At present, the common gypsum board cutting tools on the market mainly include manual cutters, electric cutters and push knives. Among them, manual cutters are easy to operate, but the cutting efficiency is low and the accuracy is difficult to guarantee; electric cutters have fast cutting speeds, but the equipment cost is high, the operation is complicated, and the technical requirements of the operator are high. In contrast, push knives, as a cutting tool between manual and electric, are gradually favored by users due to their advantages such as easy operation, high cutting accuracy and relatively low cost.
[0004] Although push knives have many advantages in gypsum board cutting, existing push knife products still have some technical problems, which limit their further application and development:
[0005] 1. Insufficient cutting stability:
[0006] During the cutting process, the traditional push knife is prone to shaking or offsetting of the cutting arm due to the lack of effective guiding and fixing mechanisms, resulting in reduced cutting accuracy and even material waste and rework.
[0007] 2. Inconvenient adjustment:
[0008] The cutting width adjustment mechanism of some push knives is not designed properly and is complicated to operate. It requires additional tools or multiple adjustments to achieve the desired cutting size, which reduces work efficiency.
[0009] 3. Not firmly fixed:
[0010] The fixing method of the cutting blade is relatively simple and lacks a reliable locking mechanism, so it is easy to loosen or fall off during the cutting process, which not only affects the cutting quality but also poses a safety hazard.
[0011] 4. Lack of accurate measurement methods:
[0012] Many push knives are not equipped with a scale or measuring device, so the operator can only cut based on experience, and it is difficult to ensure the accuracy of the cutting length, especially in situations where precise cutting is required.
[0013] 5. Lack of durability:
[0014] Some parts of the existing push knife, such as the slide rail, the guide column, etc., are prone to wear during long-term use, which affects the service life and stability of the push knife.
[0015] 6. Limited applicability:
[0016] The design of some push knives is too simple, and it is difficult to adapt to the cutting needs of materials of different thicknesses and materials, which limits their scope of application.
[0017] Therefore, a gypsum board push knife is proposed to solve the current shortcomings. Summary of the invention
[0018] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a gypsum board push knife.
[0019] In order to solve the above technical problems, the technical solution provided by the present invention is a gypsum board push knife: comprising a movable seat, a cutting arm and a cutting blade;

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the invention clearer, the technical solution in the embodiments of the invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the invention. Obviously, the described embodiments are part of the embodiments of the invention, not all of the embodiments. Generally, the components of the embodiments of the invention described and shown in the drawings here can be arranged and designed in various different configurations.
[0048] In the description of the embodiments of the invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the invention product is usually placed when in use, it is only for the convenience of describing the invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0049] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0050] In the description of the embodiments of the invention, "a plurality of" means at least two.
[0051] In the description of the embodiments of the invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.
[0052] As shown in the accompanying drawings, a gypsum board push knife includes a moving base 1, a cutting arm 2 and a cutting blade 3;
[0053] A groove 4 is provided on one side of the bottom of the movable seat 1. The groove 4 is located on one side of the bottom of the movable seat 1 and is arranged along its length direction. The height of the groove 4 matches the thickness of the gypsum board. Through the cooperation between the groove 4 and the gypsum board, the push knife is guided to move in a straight line along the edge of the gypsum board, ensuring that the push knife can fit tightly to the gypsum board during the cutting process.
[0054] In a specific implementation, the groove 4 fits tightly with the edge of the gypsum board to form a guide track. At the same time, the cooperation between the groove 4 and the gypsum board increases the contact area between the push knife and the gypsum board to effectively disperse the cutting force and prevent the push knife from tilting or shaking during the cutting process, thereby improving the stability and accuracy of the cutting.
[0055] Moreover, the setting of the groove 4 can prevent the push knife from causing unnecessary damage to the edge of the gypsum board during movement, guide the push knife to move along a preset path, avoid friction or collision between the push knife and the edge of the gypsum board, and thus protect the integrity of the gypsum board.
[0056] During use, when the operator pushes the push knife, the groove 4 slides along the edge of the gypsum board, ensuring that the push knife moves in a straight line and avoids deviation from the predetermined cutting path. At the same time, the groove 4 provides a clear guide for the operator, reducing the difficulty of operation. With the help of the groove 4, straight cutting can be easily achieved, thereby improving work efficiency.
[0057] The upper side of the movable seat 1 is provided with a sliding groove 5 for accommodating the cutting arm 2 and allowing it to slide to adjust the cutting width of the gypsum board. The cutting arm 2 is slidably arranged in the sliding groove 5. Specifically, the cutting arm 2 and the movable seat 1 are arranged horizontally and vertically, and the bottom side of the cutting arm 2 and the upper side of the groove 4 are located in the same plane, ensuring that during the cutting process, the bottom side of the cutting arm 2 contacts the gypsum board, thereby ensuring the stability of the push knife movement.
[0058] During implementation, the sliding of the cutting arm 2 in the sliding groove 5 enables the push knife to adapt to cutting requirements of different widths. The operator can accurately adjust the position of the cutting arm 2 according to the specific size of the gypsum board to achieve the required cutting width.
[0059] At the same time, the bottom side of the cutting arm 2 and the upper side of the groove 4 are located in the same plane, ensuring that the cutting arm 2 can contact the gypsum board during the cutting process, further preventing the push knife from tilting or shaking during the cutting process, thereby improving the stability and accuracy of the cutting.
[0060] Furthermore, slide grooves 11 are symmetrically provided on both sides of the sliding groove 5, and slide rails 12 cooperating with the slide grooves 11 are provided on both sides of the cutting arm 2. Through the cooperation between the slide grooves 11 and the slide rails 12, linear motion guidance is provided, while ensuring that the cutting arm 2 slides smoothly on the moving seat 1 and prevents derailment.
[0061] The matching design of the slide groove 11 and the slide rail 12 provides a precise linear motion guide for the cutting arm 2, ensuring that the cutting arm 2 always moves along a preset linear direction during the sliding process, avoiding deviation or swinging, thereby ensuring the straightness of the cutting. At the same time, the close matching of the slide rail 12 and the slide groove 11 effectively prevents the cutting arm 2 from derailing during the sliding process, improves the overall safety of the push knife, and avoids accidental injuries or equipment damage caused by derailment.
[0062] A limit seat 6 is provided on the upper side of the moving seat 1, and the limit seat 6 is fixedly connected to the moving seat 1 by bolts. The limit seat 6 is fixed to the moving seat 1 by bolts to ensure the coordination between the cutting arm 2 and the moving seat 1, and at the same time carries a locking mechanism 7 to control the fixing and release of the cutting arm 2.
[0063] The bolt connection ensures that the limit seat 6 can be firmly fixed on the moving seat 1 to prevent it from loosening or displacement during use, so as to ensure the cooperation between the cutting arm 2 and the moving seat 1.
[0064] Meanwhile, the locking mechanism 7 is used to fix or release the cutting arm 2. Specifically, through the bearing of the limiting seat 6, the locking mechanism 7 can ensure the stability and safety of the cutting arm 2 during the cutting process.
[0065] The limiting seat 6 is provided with a locking mechanism 7 that cooperates with the cutting arm 2 and is used to fix the cutting arm 2 to prevent it from moving during the cutting process.
[0066] The locking mechanism 7 includes a locking pin 71 and a locking block 72. A movable groove 13 is provided on the upper side of the cutting arm 2. The locking pin 71 is threadedly connected to the limit seat 6. The bottom end of the locking pin 71 is rotatably connected to the locking block 72. In the present embodiment, the locking block 72 is a rectangular parallelepiped structure, and the locking block 72 cooperates with the movable groove 13.
[0067] In the initial state, the locking mechanism 7 is in a loose state, and the cutting arm 2 can move freely in the sliding groove 5. When the cutting arm 2 is adjusted to a suitable position, the operator rotates the locking pin 71 to move it downward along the thread direction, and the locking block 72 moves downward and cooperates with the moving groove 13. Since the locking block 72 is a rectangular parallelepiped structure, it matches the shape of the moving groove 13. When the two are fully matched, the cutting arm 2 is fixed in the current position. Continuing to rotate the locking pin 71 will increase the friction between the locking block 72 and the moving groove 13, further enhancing the locking effect.
[0068] At this time, the locking block 72 is tightly matched with the moving groove 13, and the cutting arm 2 is effectively locked and cannot move, which can prevent any accidental movement of the cutting arm 2 during the cutting process and ensure the cutting accuracy.
[0069] When the position of the cutting arm 2 needs to be adjusted, the operator rotates the locking pin 71 counterclockwise, and the locking pin 71 moves upward. At this time, the locking block 72 is separated from the moving groove 13, and the cutting arm 2 resumes the free sliding state.
[0070] The end of the cutting arm 2 is provided with a mounting groove 8, and the cutting blade 3 is arranged in the mounting groove 8. The mounting groove 8 is used to accommodate the cutting blade 3 and provide space for the installation and adjustment of the cutting blade 3, that is, the length of the cutting blade 3 exposed from the mounting groove 8; at the same time, the extension amount of the blade is adjusted by the fixing mechanism 9.
[0071] The cutting blade 3 is arranged on one side of the cutting arm 2 close to the groove 4, and a fixing mechanism 9 cooperating with the cutting blade 3 is arranged at the end of the cutting arm 2;
[0072] The fixing mechanism 9 includes a fixing pin 91 and a guide column 92. The guide column 92 is fixedly installed on one side of the mounting groove 8 close to the movable seat 1. The cutting blade 3 is located in the mounting groove 8 and slidably cooperates with the guide column 92 to ensure that the cutting blade slides linearly in the mounting groove 8 to prevent deflection.
[0073] The fixing pin 91 is threadedly connected to the cutting arm 2 and cooperates with the cutting blade 3. The fixing pin 91 is coaxially arranged with the guide column 92.
[0074] The fixing pin 91 is connected to the cutting arm 2 via threads and can be rotated and adjusted to fix the cutting blade 3 and provide cooperation with the fixing seat 93 .
[0075] A fixing seat 93 cooperating with the cutting blade 3 is disposed at the end of the fixing pin 91 , and a guide hole 94 cooperating with the guide column 92 is disposed at the end of the fixing seat 93 .
[0076] In the initial state, the cutting blade 3 is located in the mounting groove 8 and is slidably matched with the guide column 92 and can slide freely. At this time, the fixing pin 91 is in a loose state, and the extension amount of the cutting blade 3 can be adjusted.
[0077] When the extension of the cutting blade 3 is adjusted to the required extension, the operator rotates the fixing pin 91 to move it toward the cutting blade 3 so that it fits tightly with the cutting blade 3. The fixing pin 91 provides axial force through the threaded connection to firmly fix the cutting blade 3 in the mounting groove 8.
[0078] The cutting tool further comprises a scale 10, which is arranged on one side of the cutting arm 2 and corresponds to the cutting edge 3. The scale 10 provides an intuitive reference for the operator to accurately measure and control the cutting length.
[0079] By observing the markings on the scale 10, the operator can accurately adjust the position of the cutting arm 2 to achieve the desired cutting length.
[0080] When in use, the design of the scale 10 allows the operator to quickly and conveniently adjust the position of the cutting arm 2 without using additional measuring tools, thereby simplifying the operating process and improving work efficiency.
[0081] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
