Description

Technical Field

[0001] This invention relates to the field of slitting equipment technology, specifically to a slitting machine for ultra-thin narrow-width steel strips. Background Technology

[0002] In the fields of electronic components and precision instrument manufacturing, the application of ultra-thin narrow-width steel strips (such as 1.6mm-4.0mm in width and 0.08mm-0.12mm in thickness) is becoming increasingly widespread. These materials are thin, narrow, and have low rigidity, making them prone to problems such as residual edge burrs, tension fluctuations, inaccurate metering, and material shortages during the slitting process. Furthermore, the mechanical design of traditional equipment cannot specifically address these pain points. These problems ultimately result in uneven edges, surface defects, large length deviations, and uneven tension in the slitting steel strips, severely affecting the quality of subsequent processing. Therefore, there is an urgent need for a high-precision slitting device specifically designed for ultra-thin narrow-width steel strips. Summary of the Invention

[0003] The purpose of this invention is to provide a slitting machine for ultra-thin narrow-width steel strips to solve the problems mentioned in the background art.

[0005] Furthermore, the braking unit includes a sensing lever and a sensor. When the sensing lever is subjected to an external force, it can rotate to form an angle change. The sensor is used to detect whether there is an angle change and then determine whether there is a steel strip.

[0006] Furthermore, the base includes a base plate and a base plate disposed on the base plate. The base plate can move linearly along the base plate. The base plate is provided with a slot for the steel strip to pass through. Two clamping blocks are provided on both sides of the slot.

[0014] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1 like Figures 1-6 As shown, the slitting machine for ultra-thin narrow-width steel strip in this embodiment mainly consists of a frame 10 and an unwinding unit 20, a braking unit 30, a deburring unit 40, a chip removal unit 50, a tension adjustment unit 60, a winding unit 70, and a corresponding PLC control system installed on the frame 10.

[0018] Specifically, the unwinding unit 20 releases the steel strip through the unwinding reel. A wire diameter induction encoder is installed at the output end of the unwinding reel to detect the width and thickness of the steel strip in real time and feed the detection data back to the control system. An angle induction encoder is also set in linkage to monitor the steel strip conveying angle. When monitoring the angle, the unwinding and rewinding speeds are balanced to ensure stable steel strip conveying and avoid frequent downtime.

[0019] The braking unit 30 is used to contact the released steel strip and detect whether there is a steel strip. When no steel strip is detected, it controls the unwinding unit 20 to stop. The braking unit 30 includes a sensing swing rod 31 and a sensor. The sensing swing rod 31 can rotate and change angle when subjected to external force. The sensor is used to detect whether there is an angle change and then determine whether there is a steel strip. That is, the steel strip is attached to the sensing swing rod 31 during the forward movement. When no material is detected, a signal is immediately sent to the control system to brake the unwinding reel to prevent the equipment from running dry and the steel strip from loosening. Of course, a no-material warning can also be issued through an audible and visual alarm or displayed on the control panel.

[0020] Furthermore, the deburring unit 40 includes a base and a scraper 48 disposed on the base. The base allows the steel strip to pass through, and the scraper 48 is provided with a groove for the steel strip to pass through. The groove is used to scrape off burrs on both sides of the steel strip, and the width of the groove is consistent with the required width of the steel strip, thereby removing the burrs on both sides. The base includes a base plate 41 and a base plate 42 disposed on the base plate 41. The base plate 42 can move linearly along the base plate 41. The base plate 42 is provided with a slot 43 for the steel strip to pass through. Two clamping blocks 44 are provided on both sides of the slot 43. Multiple grooves 45 at different heights are provided on the opposite end faces of the two clamping blocks 44. The edge of the steel strip is inserted into the grooves 45. The vertical height of the grooves 45 is approximately equal to the thickness of the steel strip. Thus, the steel strip can be kept in a relatively straight state, which is convenient for scraping burrs. At the same time, the steel strip can be placed at different heights. Of course, the distance between the two clamping blocks 44 is also adjustable. After moving the position, it can be locked with bolts. The distance adjustment range is between 1.5mm and 4.5mm.

[0021] Furthermore, the distance between the opposite end faces of the two clamping blocks 44 gradually increases, which improves the stability of the steel belt transportation and avoids excessive friction, thus achieving a certain scraping and flattening effect on both sides.

[0022] The base plate 42 is provided with a mounting post 46, and a mounting plate 47 is sleeved on the mounting post 46. The scraper 48 is located below the mounting plate 47. A spring 49 is sleeved on the mounting post 46 and located above the mounting plate 47. A locking member is provided at the upper end of the mounting post 46 to compress the spring 49. The locking member is a bolt. After the spring 49 is compressed, the height of the mounting plate 47 can be controlled, thereby adjusting the height of the scraper 48.

[0023] In addition, the tension adjustment unit is used to adjust the winding tension of the steel strip. The tension adjustment unit 60 includes a first adjustment module and a second adjustment module. The first adjustment module includes a first adjustment seat 61. A cylinder 62 is provided on the first adjustment seat 61. The output end of the cylinder 62 is connected to the adjustment plate 63. An adjustment groove 611 for the steel strip to pass through is provided on the first adjustment seat 61. The adjustment plate 63 can be pressed into the adjustment groove 611 and contact the steel strip. The conveying tension of the steel strip is controlled by adjusting the pressure, and it can also play a braking function.

[0024] Furthermore, the second adjustment module includes a second adjustment seat 64 and a third adjustment seat 65. The second adjustment seat 64 is provided with a channel 66 for the steel strip to pass through and an adjustment rod. The adjustment rod is driven by a knob 67 and can pass through the channel 66. The third adjustment seat 65 is provided with a pressure roller 68. The pressure roller 68 passes through the channel 66 and contacts the steel strip. The pressure roller 68 applies pressure from the vertical direction of the steel strip, while the adjustment rod can apply pressure from the horizontal direction, i.e., the edge of the steel strip, to improve the adjustment effect, keep the edge flat, and provide some burr repair.

[0025] The pressure roller 68 is made of PU with a hardness of 80°-90° and a tension adjustment range of 0-5KG.

[0026] The winding unit 70 uses a winding wheel to wind the steel strip, and a linear module can be set at its bottom to drive the winding unit 70 to move in the left and right directions.

[0027] The chip removal unit 50 is located near the deburring unit 40 and the tension adjustment unit. The chip removal unit 50 includes a blow pipe, which is used to blow out airflow at an adjustable angle to blow out the repaired burrs and prevent debris from adhering and affecting the surface accuracy of the steel strip. The blowing frequency can be adjusted by the control system, and the airflow pressure is 0.5 MPa.

[0028] Of course, a meter counter 80 can also be set at the exit position of the deburring unit 40 to count the length of the steel belt conveyor in real time. When the set winding length is reached, a feedback signal is sent to the control system to trigger subsequent shutdown or winding action to meet the quantitative winding requirements. It can also be set to be infinitely long until there is no material left.

[0029] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
