Description

Technical Field

[0001] This utility model belongs to the technical field of slitting machine equipment, and in particular relates to a metal strip slitting machine. Background Technology

[0002] Metal strip slitting machines are precision processing equipment specifically designed for metal sheets and strips. Through processes such as shearing and slitting, they transform large rolls of material into finished products of specific widths and lengths, and are widely used in electrical materials, automotive parts, and electronic components. Their core function is to achieve high-precision, high-efficiency metal strip slitting, meeting the dual requirements of modern manufacturing for material utilization and product quality. In automotive manufacturing, slitting machines can quickly cut metal sheets into standardized parts, improving production efficiency and reducing scrap rates. The electronics industry relies on their high-precision slitting of materials such as silicon steel sheets and electromagnetic steel to ensure the reliability of component dimensions. Furthermore, the equipment's versatility is demonstrated in applications such as stone processing in the construction industry and metal foil slitting in the packaging industry. By reducing subsequent deburring processes, slitting technology can significantly reduce processing costs.

[0003] Comparing with Chinese Patent CN212665020U, a metal strip slitting machine is disclosed, including a base. A slitting table is positioned at the top center of the base. Telescopic cylinders are symmetrically arranged at both ends of the slitting table. An adjusting frame is positioned at the top of each telescopic cylinder. The adjusting frame has multiple evenly arranged adjustment holes. A mounting ear is provided on one side of the adjusting frame, and a blade is housed within the mounting ear. A blade rest is positioned at the top center of the slitting table. Clamping devices are symmetrically arranged on the left and right sides of the adjusting frame. By providing blades that can be detachably connected via fixing bolts, the user can adjust the blade position according to the required material width to meet different needs. This allows the device to perform slitting operations of specific sizes for metal strips, facilitating user adjustments to the slitting dimensions or adding / removing blades as needed, thus enhancing the device's practicality.

[0004] However, the aforementioned patent uses bolts to fix the cutting tool, which can loosen and shift during long-term cutting, resulting in a significant reduction in cutting accuracy and seriously affecting the quality of metal strip cutting. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a metal strip slitting machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A metal strip slitting machine includes a frame body with take-up and take-up devices for releasing and winding metal strip at both ends of the frame body, and a cutting device for rotating and meshing to cut the metal strip in the middle of the frame body. A waste collection device for winding up waste edges is located on the output side of the cutting device on the frame body, and two waste collection devices are symmetrically arranged along the front and back of the frame body. The cutting device includes a punch roller and a die roller distributed parallel to each other vertically. A first motor is installed at one end of the punch roller, and a drive gear is installed at the end of the punch roller away from the first motor. A driven gear is installed at one end of the die roller, and the drive gear and driven gear mesh for transmission. The waste collection device includes a fixed frame mounted on the outside of the frame body, a second motor mounted on the fixed frame, a winding roller mounted at the output end of the second motor, and a guide component on one side of the winding roller for guiding the waste edges through the frame body and moving up and down to wind them evenly.

[0008] Furthermore: the guiding assembly includes a through groove provided on the frame body, a guide roller rotatably installed in the through groove, a guide frame for reciprocating up and down is provided between the guide roller and the winding roller, and a wire guide sleeve is installed in the middle of the guide frame.

[0009] Furthermore: the guide frame is driven by a linear motor to move up and down along the machine frame.

[0010] Furthermore: the punch roller and the die roller interlock and mesh along the length direction.

[0011] Furthermore, the take-up and take-up device includes a feed roller and a take-up roller, with a third motor installed at one end of the feed roller and a fourth motor installed at one end of the take-up roller.

[0012] Furthermore, a limit rod is installed on the frame near the feeding roller.

[0013] Furthermore: the limiting rod is set horizontally, and the height of the limiting rod is lower than that of the die roller.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] The machine employs parallel, vertically distributed punch and die rollers for rotating and meshing slitting, enabling continuous, high-speed slitting of metal strips to specific dimensions, significantly improving production efficiency and stability. The meshing transmission of drive and driven gears ensures absolute synchronous rotation of the punch and die rollers, avoiding problems such as strip pulling, deformation, or uneven edges caused by speed differences, thus guaranteeing the flatness and high precision of the slit. Two waste collection devices are symmetrically arranged along the front and rear of the frame; this symmetrical layout ensures that waste generated on both sides of the slitting process is collected simultaneously. The even collection avoids asymmetrical tension caused by unilateral material collection, thus ensuring the alignment of the strip on the slitting center line and further improving slitting accuracy and equipment stability. The guide frame driven by a linear motor moves the wire guide sleeve back and forth along the winding roller axis, guiding the waste edge to be evenly and neatly wound on the winding roller, effectively preventing the waste edge from accumulating in local areas on the roller, thereby increasing the capacity of a single winding, reducing the frequency of downtime for changing rolls, and avoiding problems such as jamming and wire breakage caused by uneven winding, thus improving the reliability of collection.

[0026] Please see Figures 1-5A metal strip slitting machine includes a frame body 1, with a take-up and take-up device 2 at both ends of the frame body 1 for releasing and taking up metal strip, and a cutting device 3 in the middle of the frame body 1 for rotating and engaging to cut the metal strip. A waste collection device 4 for taking up waste edges is provided on the side of the cut device 3 on the frame body 1. Two waste collection devices 4 are symmetrically arranged along the front and back of the frame body 1.

[0027] In this embodiment: the take-up and take-down device 2 includes a feed roller 21 and a take-up roller 23. A third motor 22 is provided at one end of the feed roller 21, and a fourth motor 24 is provided at one end of the take-up roller 23.

During operation, the frame body 1 supports the third motor 22 to drive the feed roller 21 to rotate and release the metal strip. The fourth motor 24 drives the take-up roller 23 to wind the slit metal strip, ensuring that the metal strip moves stably between the punch roller 31 and the die roller 32. At the same time, under the flattening intervention of the limit rod 5, the metal strip moves into the space between the punch roller 31 and the die roller 32.

[0028] In this embodiment: the cutting device 3 includes a punch roller 31 and a die roller 32 arranged in parallel. A first motor 35 is provided at one end of the punch roller 31, and a drive gear 33 is provided at the end of the punch roller 31 away from the first motor 35. A driven gear 34 is provided at one end of the die roller 32. The drive gear 33 and the driven gear 34 mesh and drive each other. The punch roller 31 and the die roller 32 overlap and mesh along the length direction. The metal strip moves into the space between the punch roller 31 and the die roller 32. The first motor 35 drives the punch roller 31 to rotate. At the same time, the drive gear 33 at the end of the punch roller 31 meshes with the driven gear 34 to drive the die roller 32 to rotate synchronously, thereby cutting the metal strip.

[0029] In this embodiment: the waste collection device 4 includes a fixed frame 46 installed on the outside of the frame body 1, a second motor 48 is installed on the fixed frame 46, a winding roller 47 is installed at the output end of the second motor 48, and a guide component is provided on one side of the winding roller 47 for guiding the waste edge through the frame body 1 and moving up and down to wind evenly; the guide component includes a through groove 41 provided on the frame body 1, a guide roller 42 is rotatably installed in the through groove 41, and a guide frame 44 for reciprocating up and down is provided between the guide roller 42 and the winding roller 47, and a guide frame 44 is installed in the middle of the guide frame 44.

Under the guidance of the guide roller 42, the waste edges pass through the through groove 41 and out of the machine frame 1, pass through the wire sleeve 45 on the guide frame 44 and wind onto the winding roller 47. The guide frame 44 is driven by the linear motor 43 to move up and down along the machine frame 1, so that the wire sleeve 45 moves back and forth along the axial direction of the winding roller 47, thereby improving the uniformity of the waste edge winding.

[0030] Working principle: During operation, the frame 1 supports the third motor 22, which drives the unloading roller 21 to rotate and release the metal strip. The fourth motor 24 drives the take-up roller 23 to wind the slit metal strip, ensuring the metal strip moves stably between the punch roller 31 and the die roller 32. Simultaneously, under the flattening intervention of the limit rod 5, the metal strip moves into the space between the punch roller 31 and the die roller 32. The first motor 35 drives the punch roller 31 to rotate, and at the same time, the drive gear 33 at the end of the punch roller 31 meshes with the driven gear 34 to drive the die roller 32. The die-rotating roller 32 rotates synchronously to cut the metal strip. During this process, the fixed frame 46 supports the second motor 48 to drive the winding roller 47 to rotate and wind the waste edges cut off from both sides of the metal strip. Under the guidance of the guide roller 42, the waste edges pass through the through groove 41 and out of the frame 1, pass through the wire guide sleeve 45 on the guide frame 44 and wind onto the winding roller 47. The guide frame 44 moves up and down along the frame 1 under the drive of the linear motor 43, so that the wire guide sleeve 45 moves back and forth along the axial direction of the winding roller 47, thereby improving the uniformity of the waste edge winding.
