[0002] Metal sheet cutting machines are processing equipment specifically designed for cutting thin metal sheets such as steel plates and aluminum plates. They separate sheets according to preset sizes and shapes to complete the pre-processing of blanking or forming. They are widely used in manufacturing fields such as automotive parts, home appliance housings, and hardware accessories.

[0003] In the prior art, Chinese Patent No. CN220161143U discloses a circular die-cutting device for metal sheet processing, including a box body. A control panel is provided on the front side wall of the box body, and a door is provided at the center of the front face of the box body. A frame is provided on both sides of the center of the upper face of the box body. A waste bin is provided at the center of the inside of the box body. Two waste pipes are provided on both sides of the center of the upper face of the box body. A sliding groove is provided at the center of the two inner side walls of the frame body. A first motor is provided on both sides of the center of the upper inner wall of the frame body. The output ends of the two first motors pass through the upper face of the sliding groove and extend into the sliding groove, and the ends of the motors are fixedly connected to lead screws. During the operation, the waste generated by the cut metal sheet material flows into the waste bin through the waste pipes, which facilitates the centralized processing of the waste, avoids a dirty and messy work site, and effectively improves the processing efficiency.

[0004] Based on the above information, existing metal sheet cutting machines are prone to problems such as deviation and tilting during continuous conveying or high-speed movement of metal sheets due to factors such as inertia and uneven tension. This leads to inaccurate alignment in subsequent cutting processes and reduces the product qualification rate. Therefore, we propose a deviation correction feeding mechanism for metal sheet cutting machines. Utility Model Content

[0005] The purpose of this utility model is to provide a correction feeding mechanism for a metal sheet cutting machine, so as to solve the problem that in the actual use of the prior art metal sheet cutting machine mentioned in the background, the metal sheet is easily affected by factors such as inertia and uneven tension when it is continuously conveyed or moved at high speed, resulting in deviation and tilting, which leads to the inability to accurately align the subsequent cutting process and reduce the product qualification rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a correction and feeding mechanism for a metal sheet cutting machine, comprising a cutting machine body, a feeding port at the end of the cutting machine body, and a mounting frame inside the feeding port, two sets of feeding rollers symmetrically arranged on the side wall of the mounting frame, and a drive motor at the end of one set of feeding rollers, an adjusting roller slidably mounted on the side wall of the mounting frame, and correction mechanisms for preventing metal sheet deviation on both sides of the feeding rollers, the correction mechanism including an adjusting rod slidably mounted on the bottom of the mounting frame, and two sets of correction rollers symmetrically distributed at both ends of the adjusting rod, a linkage rotating rod rotatably mounted on the bottom of the mounting frame, and a cleaning mechanism for removing dust from the surface of the metal sheet at the feeding end of the mounting frame.

[0007] Furthermore, two sets of adjusting rollers are symmetrically arranged, and the adjusting rollers are parallel to the feeding rollers. The metal sheet is located between the adjusting rollers and the feeding rollers. Two sets of hydraulic cylinders are symmetrically arranged on the outer walls of both sides of the mounting frame, and a connecting frame is fixedly installed at the output end of the hydraulic cylinder. The connecting frame is fixedly connected to the ends of the two sets of adjusting rollers, which is used to adjust the distance between the feeding rollers and the adjusting rollers according to the thickness of the metal sheet.

[0008] Furthermore, two sets of adjusting rods are symmetrically arranged, and the adjusting rods are perpendicular to the feeding rollers. The length of the adjusting rods is greater than the distance between the two sets of feeding rollers. The correction rollers are arranged parallel to the metal sheet, and the outer wall of the correction rollers is in contact with the side wall of the metal sheet.

[0009] Furthermore, the linkage rod is located between the two sets of adjusting rods, and both ends of the linkage rod are hinged to connecting rods, with the end of the connecting rod away from the linkage rod hinged to the center of the adjusting rod.

[0010] Furthermore, an electric actuator is fixedly installed on the side wall of the mounting bracket, and the output end of the electric actuator is fixedly connected to the side wall of one of the sets of adjusting rods.

[0011] Furthermore, the cleaning mechanism includes a fixed plate that is fixedly installed at the end of the connecting frame and on the side wall of the mounting frame, and a cleaning block is slidably installed on the outer wall of the fixed plate. A compression spring is provided inside the fixed plate.

[0012] Furthermore, the fixing plate at the end of the connecting frame is symmetrically arranged with the fixing plate on the side wall of the mounting frame, and the metal sheet is located between the two sets of fixing plates, with the outer wall of the cleaning block in contact with the surface of the metal sheet.

[0013] Furthermore, the compression springs are evenly spaced, with one end of the compression spring abutting against the outer wall of the cleaning block and the other end of the compression spring abutting against the inside of the fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The correction feeding mechanism of this metal sheet cutting machine, by setting a correction mechanism, can drive two sets of symmetrical correction rollers to move synchronously in opposite directions, accurately fit the sidewalls of metal sheets of different widths, effectively counteract the offset force caused by inertia and uneven tension during the conveying process, avoid the sheet tilting and misalignment, ensure the accurate alignment of subsequent cutting processes, and significantly improve the product qualification rate; at the same time, the rolling contact between the correction rollers and the sheet can reduce friction damage and ensure the integrity of the sheet surface.

[0015] 2. The hydraulic cylinder drives the connecting frame to raise and lower the adjusting roller, which can flexibly adjust the distance between the feeding roller and the adjusting roller, adapting to metal sheets of different thicknesses and achieving stable clamping and conveying. This avoids slippage when conveying thin materials and prevents deformation of thick materials under pressure, thus improving the versatility and adaptability of the mechanism.

[0016] 3. By symmetrically setting the cleaning mechanism, the elastic force of the compression spring is used to make the cleaning block tightly adhere to the upper and lower surfaces of the metal sheet. Dust removal and cleaning are completed simultaneously during the sheet conveying process, removing dust, debris and other impurities from the surface. This not only avoids impurities affecting cutting accuracy and cut quality, but also reduces wear on the cutting tool and extends the service life of the equipment. At the same time, the buffering effect of the compression spring ensures the stability of the cleaning effect. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a correction feeding mechanism for a metal sheet cutting machine, comprising a cutting machine body 1, a feeding port 2 at the end of the cutting machine body 1, and a mounting frame 3 inside the feeding port 2, two sets of feeding rollers 401 symmetrically arranged on the side wall of the mounting frame 3, and a drive motor 4 at the end of one set of feeding rollers 401, an adjusting roller 5 slidably mounted on the side wall of the mounting frame 3, and correction mechanisms for preventing metal sheet deviation on both sides of the feeding rollers 401, the correction mechanism including an adjusting rod 6 slidably mounted on the bottom of the mounting frame 3, and two sets of correction rollers 601 symmetrically distributed at both ends of the adjusting rod 6, and a linkage rotating rod 602 rotatably mounted on the bottom of the mounting frame 3.

[0021] like Figures 1-6 As shown, two sets of adjusting rollers 5 are symmetrically arranged, and the adjusting rollers 5 and the feeding rollers 401 are arranged in parallel. The metal sheet is located between the adjusting rollers 5 and the feeding rollers 401. Two sets of hydraulic cylinders 502 are symmetrically arranged on the outer walls of both sides of the mounting frame 3. A connecting frame 501 is fixedly installed at the output end of the hydraulic cylinders 502. The connecting frame 501 is fixedly connected to the ends of the two sets of adjusting rollers 5, and is used to adjust the distance between the feeding rollers 401 and the adjusting rollers 5 according to the thickness of the metal sheet.

[0022] like Figure 4 and Figure 5 As shown, there are two sets of adjusting rods 6 symmetrically arranged, and the adjusting rods 6 are perpendicular to the feeding rollers 401. The length of the adjusting rods 6 is greater than the distance between the two sets of feeding rollers 401. The correction rollers 601 are parallel to the metal sheet, and the outer wall of the correction rollers 601 is in contact with the side wall of the metal sheet. The linkage rotating rod 602 is located between the two sets of adjusting rods 6, and both ends of the linkage rotating rod 602 are hinged to connecting rods 603. The end of the connecting rod 603 away from the linkage rotating rod 602 is hinged to the center of the adjusting rod 6.

[0023] like Figures 1-6 As shown, an electric actuator 604 is fixedly installed on the side wall of the mounting bracket 3, and the output end of the electric actuator 604 is fixedly connected to the side wall of one of the adjusting rods 6.

[0024] After starting the drive motor 4, it drives a set of feeding rollers 401 to rotate. The feeding rollers 401 and the adjusting rollers 5 work together to form a clamping and conveying force on the metal sheet, conveying the metal sheet from the feeding end of the mounting frame 3 into the body of the cutting machine 1. When dealing with metal sheets of different thicknesses, the hydraulic cylinders 502 on both sides of the mounting frame 3 are controlled to push or pull the connecting frame 501. Since the connecting frame 501 is fixedly connected to the ends of the two sets of adjusting rollers 5, the adjusting rollers 5 will slide along the side wall of the mounting frame 3, thereby changing the distance between the feeding rollers 401 and the adjusting rollers 5 until the distance is adapted to the thickness of the metal sheet, realizing stable clamping and conveying of sheets of different thicknesses, avoiding slippage of thin materials or deformation of thick materials under pressure. Before conveying the metal sheet, the electric push rods 6 on the side wall of the mounting frame 3 are activated according to the width of the sheet. 04. The output end of the electric actuator 604 pushes a set of adjusting rods 6 connected to it to slide along the bottom of the mounting frame 3. Since the two ends of the linkage rotating rod 602 are respectively hinged to the center of the two sets of adjusting rods 6 through the connecting rod 603, when one set of adjusting rods 6 moves, it will drive the linkage rotating rod 602 to rotate through the connecting rod 603. The linkage rotating rod 602 then pulls the other set of adjusting rods 6 to slide synchronously in the opposite direction through the other set of connecting rods 603, so that the correction rollers 601 at both ends of the two sets of adjusting rods 6 move synchronously towards or in the opposite direction until the outer wall of the correction roller 601 is in close contact with the side wall of the metal sheet. During the sheet conveying process, if there is a tendency to deviate, the correction roller 601 will generate a lateral limiting force on the side wall of the sheet to counteract the deviation force, ensuring that the sheet is always conveyed along the preset path, avoiding tilting and misalignment, and ensuring accurate alignment for subsequent cutting.

[0025] Example 2: Please refer to Figures 1-7 Based on Embodiment 1, a cleaning mechanism is also disclosed, the specific structure of which is as follows: The feeding end of the mounting frame 3 is provided with a cleaning mechanism for dust removal from the surface of the metal sheet. The cleaning mechanism includes a fixing plate 7 fixedly installed at the end of the connecting frame 501 and the side wall of the mounting frame 3, and a cleaning block 8 is slidably installed on the outer wall of the fixing plate 7. A compression spring 801 is provided inside the fixing plate 7. The fixing plate 7 at the end of the connecting frame 501 and the fixing plate 7 on the side wall of the mounting frame 3 are symmetrically arranged, and the metal sheet is located between the two sets of fixing plates 7. The outer wall of the cleaning block 8 is in contact with the surface of the metal sheet. The compression springs 801 are evenly distributed, and one end of the compression spring 801 abuts against the outer wall of the cleaning block 8, and the other end of the compression spring 801 abuts against the inside of the fixing plate 7.

[0026] The fixing plates 7 of the cleaning mechanism are fixed to the end of the connecting frame 501 and the side wall of the mounting frame 3 respectively, and the two sets of fixing plates 7 are symmetrically distributed. When the metal sheet is conveyed, it will pass through the two sets of fixing plates 7. One end of the compression springs 801, which are equally spaced inside the fixing plates 7, abuts against the outer wall of the cleaning block 8. Under the elastic force of the compression springs 801, the cleaning block 8 will be tightly attached to the upper and lower surfaces of the metal sheet. When the sheet is continuously conveyed forward, the cleaning block 8 will slide relative to the surface of the sheet, thereby wiping away the dust, debris and other impurities attached to the surface of the sheet. At the same time, the compression springs 801 have a certain buffering capacity, always keeping the cleaning block 8 in contact with the surface of the sheet, ensuring stable dust removal and cleaning effect, and avoiding impurities from affecting cutting accuracy or wearing out the cutting tool.
