Description

Technical Field

[0001] This utility model relates to the field of knife and scissor straightening technology, and in particular to a knife and scissor processing straightening device. Background Technology

[0002] Knives and scissors are common tools in daily life and industrial production. Their production process usually includes a stamping process, where pressure is applied to metal sheets using a stamping machine to form the basic shape of the knives and scissors. After stamping, due to factors such as stress release of the metal material and uneven stamping pressure, the scissor blades will bend and deform to a certain extent, making them unsuitable for direct use or further processing. Therefore, they need to be straightened using specialized straightening equipment to ensure the flatness and performance of the knives and scissors.

[0003] In actual production, traditional knife and scissor straightening devices have many shortcomings: On the one hand, the lack of an effective feeding and straightening mechanism results in inconsistent postures of the shear blades output from the stamping machine as they enter the straightening equipment, easily leading to deviation and tilting, which reduces straightening accuracy and affects product quality. On the other hand, during the straightening process, some shear blades may warp due to excessive conveying speed or their own shape characteristics, further reducing the straightening effect. Simultaneously, the traditional device lacks a corresponding feeding and discharging structure, resulting in messy collection of straightened shear blades, increasing the workload for subsequent processing, and the overall connection between conveying and straightening is not smooth enough, affecting production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a knife and scissor straightening device, which overcomes the deficiencies of existing technologies and effectively solves the problems of irregular feeding posture, easy warping of knife and scissor blades during straightening, poor connection between feeding and discharging, and messy collection in traditional straightening devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A straightening device for cutting and scissing includes a conveyor frame, a straightening frame welded to one end of the conveyor frame, and a belt conveyor installed on the inner wall of the conveyor frame. The top of one end of the belt conveyor is provided with adjacent feeding rails for connecting to a stamping machine, and adjacent aligning plates are installed on the outer wall of the belt conveyor. The inner wall of the straightening frame is equipped with symmetrically distributed electric straightening rollers, and the bottom of one end of the straightening frame's outer wall is provided with adjacent discharge rails, with a stacking rack installed on the bottom outer wall of the discharge rails.

[0006] Preferably, the feeding slide rail and the discharging slide rail correspond one-to-one.

[0007] Preferably, the top outer wall of the aligning plate is welded with a connecting column, and the connecting column is fixedly connected to the inner walls of both sides of the conveyor frame.

[0008] Preferably, the inner walls on both sides of the straightening frame are welded with crossbeams, and the discharge slide rail is welded to the bottom outer wall of the crossbeams.

[0009] Preferably, an anti-tilting roller is provided inside the conveyor frame above the belt conveyor, and end sleeves are provided on the outer walls of both ends of the anti-tilting roller.

[0010] Preferably, a fixing plate is welded to the top of the outer walls on both sides of the conveyor frame, and a guide rod is fixedly connected to the bottom outer wall of the fixing plate. The guide rod is slidably connected to the inner wall of the end sleeve, and a spring is fixedly connected between the end sleeve and the fixing plate.

[0011] The beneficial effects of this utility model are as follows: 1. The shearing straightening device designed in this paper, by setting adjacent straightening plates on the belt conveyor and fixing them to the inner walls of both sides of the conveyor frame via connecting columns, can effectively straighten the shearing blades entering from the press via the feeding slide rail. This ensures that the shearing blades enter the straightening process in a regular posture, solving the problem of low straightening accuracy caused by inconsistent feeding posture in traditional devices. Simultaneously, the feeding slide rail and the discharging slide rail are set in a one-to-one correspondence, ensuring orderly connection between feeding and discharging. Combined with the stacking rack, the straightened shearing blades are centrally and neatly collected, reducing subsequent processing workload and significantly improving production efficiency. 2. The cutting and scissor straightening device in this design features an anti-warping roller installed above the belt conveyor inside the conveyor frame. The anti-warping roller is connected to the fixed plate via an end sleeve and a guide rod, and a spring is installed between the end sleeve and the fixed plate. The elastic force of the spring ensures that the anti-warping roller always fits against the surface of the cutting and scissor blades, effectively preventing warping during conveying and ensuring the stability of the straightening process. In addition, the symmetrically distributed electric straightening rollers inside the straightening frame can apply uniform pressure to straighten the cutting and scissor blades, resulting in better straightening effect. The crossbeam's fixing effect on the discharge slide rail enhances the stability of the discharge structure, further ensuring the overall reliability of the equipment. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-4 Example 1: A knife and scissor processing straightening device includes a conveyor frame 1, a straightening frame 5 welded to one end of the conveyor frame 1, a belt conveyor 2 installed on the inner wall of the conveyor frame 1, a feeding slide rail 3 for connecting a punching machine is provided on the top of one end of the belt conveyor 2, and a straightening plate 4 is installed on the outer wall of the belt conveyor 2.

[0016] Through the above scheme, the conveyor frame 1 serves as the basic support structure of the entire device, providing an installation carrier for components such as the belt conveyor 2 and the anti-tilting roller 11. The straightening frame 5 welded to one end of the frame can stably support straightening components such as the electric straightening roller 6, ensuring structural stability during the straightening process. The feeding slide rail 3 is specifically used to connect to the discharge end of the stamping machine, enabling the stamped scissor blades to be smoothly and accurately conveyed onto the belt conveyor 2, preventing them from falling or shifting during the conveying process. The belt conveyor 2 provides power for the conveying of the scissor blades. The aligning plates 4 installed on its outer wall are distributed adjacently, which can limit and guide the scissor blades on both sides during the conveying process, gradually adjusting the scissor blades with different postures to a uniform direction, laying the foundation for the subsequent straightening process.

[0017] In the second embodiment, electric straightening rollers 6 are symmetrically distributed on the inner wall of the straightening frame 5. The bottom of the outer wall of one end of the straightening frame 5 is provided with adjacent discharge slide rails 7, and the bottom outer wall of the discharge slide rail 7 is provided with a stacking rack 8. The feeding slide rail 3 and the discharge slide rail 7 correspond one-to-one.

[0018] Through the above-described scheme, the symmetrically distributed electric straightening rollers 6 installed on the inner wall of the straightening frame 5 can rotate in opposite directions when powered on, applying a uniform squeezing force to the passing scissor blades, thereby correcting the bending deformation of the scissor blades and achieving a precise straightening effect. The discharge slide rail 7 is located at the bottom of the outer wall of one end of the straightening frame 5, corresponding one-to-one with the feeding slide rail 3, ensuring that each scissor blade entering via the feeding slide rail 3 is straightened and then output through the corresponding discharge slide rail 7, avoiding confusion. The stacking rack 8 is located at the bottom of the discharge slide rail 7, capable of receiving and neatly stacking the straightened scissor blades that slide down from the discharge slide rail 7, facilitating unified collection and processing by subsequent staff and improving the continuity of the production process.

[0019] The top outer wall of the aligning plate 4 is welded with a connecting column 9, and the connecting column 9 is fixedly connected to the inner walls of both sides of the conveyor frame 1.

[0020] With the above solution, the bottom of the connecting column 9 is welded and fixed to the top outer wall of the aligning piece 4, while the top is fixedly connected to the inner walls on both sides of the conveyor frame 1. This connection method can firmly fix the aligning piece 4 on both sides above the belt conveyor 2, ensuring that the aligning piece 4 will not shift due to collision or friction during the conveying of the scissor pieces, thus ensuring the stability and durability of the aligning effect. At the same time, the length of the connecting column 9 is reasonably designed and will not affect the normal conveying of the scissor pieces.

[0021] The straightening frame 5 has crossbeams 10 welded to the inner walls on both sides, and the discharge slide rail 7 is welded to the bottom outer wall of the crossbeam 10.

[0022] Through the above-described scheme, the crossarm 10 is welded to the inner walls of both sides of the straightening frame 5, forming a stable support structure. The discharge slide rail 7 is welded to the bottom outer wall of the crossarm 10, which effectively improves the installation stability of the discharge slide rail 7 and prevents it from deforming or loosening due to force during the sliding of the scissor blades. The crossarm 10 also allows for a more reasonable installation height of the discharge slide rail 7, ensuring that the scissor blades can smoothly slide into the discharge slide rail 7 after exiting the electric straightening roller 6, achieving a smooth connection between straightening and discharge.

[0023] An anti-tilting roller 11 is installed inside the conveyor frame 1 above the belt conveyor 2, and end sleeves 12 are provided on the outer walls of both ends of the anti-tilting roller 11. A fixing plate 13 is welded to the top of the outer walls on both sides of the conveyor frame 1, and a guide rod 14 is fixedly connected to the bottom outer wall of the fixing plate 13. The guide rod 14 is slidably connected to the inner wall of the end sleeve 12, and a spring 15 is fixedly connected between the end sleeve 12 and the fixing plate 13.

[0024] With the above-described design, the anti-warping roller 11 is positioned above the belt conveyor 2, with its end sleeves 12 fitted onto the guide rods 14. The guide rods 14 are fixed to the bottom of the fixed plate 13, which is welded to the top of the outer walls on both sides of the conveyor frame 1, forming a complete anti-warping mechanism. When the spring 15 between the end sleeves 12 and the fixed plate 13 is in a naturally extended state, it can push the anti-warping roller 11 downward to conform to the scissor blades on the belt conveyor 2. When the scissor blades show a warping tendency, the anti-warping roller 11 will apply downward pressure to the scissor blades under the elastic action of the spring 15, suppressing the warping phenomenon. The sliding connection design between the guide rods 14 and the end sleeves 12 allows the anti-warping roller 11 to be finely adjusted up and down according to the thickness of the scissor blades, adapting to the conveying needs of scissor blades of different specifications, while ensuring that the pressure is always uniform.

[0025] Working principle: First, the cutter blades processed by the stamping machine are smoothly conveyed to the belt conveyor 2 inside the conveyor frame 1 via the feeding slide rail 3 connected to the discharge end of the stamping machine. The feeding slide rail 3 corresponds one-to-one with the subsequent discharge slide rail 7 to ensure the orderly conveying path. Next, the belt conveyor 2 starts running, driving the cutter blades towards the straightening frame 5. During this process, the aligning plate 4 fixed on the outer wall of the belt conveyor 2 by the connecting column 9 limits and guides both sides of the cutter blades, adjusting the irregularly shaped cutter blades to a uniform direction to ensure the accuracy of subsequent straightening.

[0026] During the conveying process of the scissor blades, the anti-warping roller 11 located inside the conveyor frame 1 above the belt conveyor 2 plays a crucial role. The end sleeves 12 at both ends of the anti-warping roller 11 are fitted onto the guide rods 14, which are fixed to the bottom of the fixed plate 13. The springs 15 between the end sleeves 12 and the fixed plate 13 provide continuous downward pressure to the anti-warping roller 11, ensuring that the anti-warping roller 11 always fits in close contact with the surface of the scissor blades. This effectively suppresses warping of the scissor blades caused by conveying speed or their own shape. At the same time, the sliding fit between the guide rods 14 and the end sleeves 12 allows the anti-warping roller 11 to be flexibly adjusted according to the thickness of the scissor blades, adapting to the needs of different product specifications.

[0027] After the scissor blades, having undergone alignment and anti-warping treatment, enter the straightening frame 5, the electrically driven straightening rollers 6, symmetrically distributed on the inner wall of the straightening frame 5, are energized and rotate in opposite directions, applying a uniform squeezing force to the scissor blades. This roller pressure corrects the bending deformation of the scissor blades, achieving precise straightening. The straightened scissor blades continue to be conveyed forward, entering the discharge slide rail 7 at one end of the straightening frame 5. The discharge slide rail 7 is securely welded to the inner walls of both sides of the straightening frame 5 via crossbeams 10, ensuring conveying stability. Finally, the scissor blades slide smoothly from the discharge slide rail 7 into the stacking rack 8 at the bottom, where they are neatly stacked for easy collection by staff.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
