Description

Technical Field

[0001] This utility model relates to the field of metal strip slitting technology, specifically a metal strip slitting device. Background Technology

[0002] Metal strip refers to a flat, rolled non-ferrous metal product with a rectangular cross-section and uniform thickness. For aluminum plates, the thickness is greater than 0.20 mm, and for copper plates, the thickness is greater than 0.15 mm. The strip is usually trimmed longitudinally and supplied in coils. The thickness of the strip is no more than one-tenth of its width. In further processing or use, the metal strip will be further slitting as needed to achieve the required width.

[0003] Currently, when slitting metal strips, width adjustment is required. However, width adjustment can only adjust the width of a single slitting operation, making it difficult to slit multiple strips simultaneously. Furthermore, the lack of traction coordination during slitting also affects the overall efficiency and the coordination of the slitting process.

[0004] As disclosed in CN220950495U, a metal strip slitting device uses a combination of accessories. Rollers that cooperate with winding are set on the side of the frame, and a slitting frame is assembled and installed on the top of the frame. Multiple L-shaped frames are installed and combined on the slitting frame according to the slitting requirements of the metal strip. The L-shaped frames are equipped with slitting wheels driven by a slitting motor, which facilitates adjustable slitting of the metal strip. The structure is simple and easy to implement.

[0005] However, during use, the L-shaped frame can only be fixedly installed in the slitting frame groove by the limiting rod. Since the positions of two adjacent slots are fixed, the positions between two adjacent slitting wheels are also fixed. Therefore, the slitting width of the metal strip is limited, and it is impossible to cut metal strips of arbitrary width, which limits its use.

[0006] Therefore, we urgently need to provide a metal strip slitting device. Utility Model Content

[0007] The purpose of this invention is to provide a metal strip slitting device to solve the problem mentioned in the background art that it is impossible to cut metal strips of arbitrary width and has limited applicability.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a metal strip slitting device, comprising a panel and a take-up roller, wherein the take-up roller is installed on the right side of the panel, and a slitting device is provided on the top of the panel, the slitting device comprising an adjustment unit, a tensioning unit and a measuring unit.

[0009] The adjustment unit is located at the top of the panel, the tensioning unit is located on the left side of the top of the panel, and the measuring unit is located at the top of the adjustment unit.

[0010] The adjustment unit includes a support plate, a slide rail, a slider, a bracket, a slitting blade, a fixing block, a threaded rod, and a pressure plate. The support plate is fixedly installed on the front and rear sides of the top of the panel. The slide rail is fixedly installed on one side adjacent to the front and rear support plates. The slider is slidably connected to the outside of the slide rail. The bracket is fixedly installed at the bottom of the slider. The slitting blade is installed inside the bracket. The fixing block is fixedly installed on the top left side of the slider. The threaded rod is threadedly connected to the inside of the fixing block. The pressure plate is fixedly installed at the bottom of the threaded rod.

[0011] Preferably, the upper end of the bracket is provided with an internal thread, and the threaded rod is threadedly connected inside the bracket. By rotating the threaded rod to connect with the bracket, the pressure plate moves down and abuts against the top of the slide rail, thereby fixing the position of the slider and thus fixing the position of the slitting blade.

[0012] Preferably, the slide rail is I-shaped, and there are multiple sliders that are slidably connected to the outside of the slide rail. By sliding the sliders along the slide rail, the slitting blade can be moved to any position on the slide rail, and the distance between two adjacent slitting blades can be adjusted to any distance, thereby slitting the metal strip into any width.

[0013] Preferably, the tensioning unit includes a mounting frame, a lower pressure roller, a threaded rod II, a moving block, and an upper pressure roller. The mounting frame is fixedly installed on the front and rear sides of the top of the panel. The lower pressure roller is installed on the lower end of one of the two adjacent mounting frames. The threaded rod II is threaded into the inside of the mounting frame. The moving block is threaded into the outside of the threaded rod II. The upper pressure roller is installed on one of the two adjacent moving blocks.

[0014] Preferably, the front and rear mounting brackets have rectangular grooves inside, and the width of the rectangular grooves is equal to the width of the moving block. By rotating the front and rear threaded rods and connecting them to the moving block, the moving block drives the upper pressure roller to move up and down along the rectangular groove, thereby adjusting the distance between the lower pressure roller and the upper pressure roller, and thus adjusting the tension of the metal strip.

[0015] Preferably, the measuring unit includes a pointer and a scale, with the pointer fixedly mounted on the right side of the fixing block and the scale fixedly mounted on the top of the slide rail.

[0016] Preferably, the bottom of the pressure plate is provided with anti-slip texture, which increases the friction between the pressure plate and the slide rail, thereby making the slider stably fixed on the slide rail.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This metal strip slitting device, by setting an adjustment unit, allows the slitting blade to be moved to any position on the slide rail by pushing the slider along the slide rail, and the distance between two adjacent slitting blades can be adjusted to any distance, thereby slitting the metal strip into any width, solving the problem in the background technology that it is impossible to slitting metal strips of arbitrary width, which limits its use.

[0019] 2. This metal strip slitting device, by setting a tensioning unit, connects the two front and rear threaded rods to the moving block by rotating them, so that the moving block drives the upper pressure roller to move up and down along the rectangular groove, thereby adjusting the distance between the lower pressure roller and the upper pressure roller, thus realizing the adjustment of the metal strip tension, making the metal strip on the winding roller more compact.

[0025] 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.

[0026] Please see Figures 1-4 This utility model provides a technical solution: Example 1:

[0027] A metal strip slitting device includes a panel 1 and a take-up roller 2. The take-up roller 2 is installed on the right side of the panel 1, and the slitting device is provided on the top of the panel 1. The slitting device includes an adjustment unit, a tensioning unit and a measuring unit.

[0028] The adjustment unit is located at the top of panel 1, the tensioning unit is located on the top left side of panel 1, and the measuring unit is located at the top of the adjustment unit.

[0029] The adjustment unit includes a support plate 301, a slide rail 302, a slider 303, a bracket 304, a slitting blade 305, a fixing block 306, a threaded rod 307, and a pressure plate 308. The support plate 301 is fixedly installed on the front and rear sides of the top of the panel 1. The slide rail 302 is fixedly installed on one side adjacent to the front and rear support plates 301. The slider 303 is slidably connected to the outside of the slide rail 302. The slide rail 302 is I-shaped. There are multiple sliders 303, which are slidably connected to the outside of the slide rail 302. By sliding the slider 303 along the slide rail 302, the slitting blade 305 can be moved to any position on the slide rail 302, and the distance between two adjacent slitting blades 305 can be adjusted to any distance, thereby slitting the metal strip into any width. The bracket 304 is fixedly installed on the slide rail 305. The bottom of block 303 and the upper end of bracket 304 are provided with internal threads. Threaded rod 307 is threadedly connected to the inside of bracket 304. By rotating threaded rod 307 and connecting it to bracket 304, pressure plate 308 moves down and abuts against the top of slide rail 302, fixing the position of slider 303 and thus fixing the position of slitting blade 305. Sliding blade 305 is installed inside bracket 304. Fixing block 306 is fixedly installed on the top left side of slider 303. Threaded rod 307 is threadedly connected to the inside of fixing block 306. Pressure plate 308 is fixedly installed at the bottom of threaded rod 307. Anti-slip texture is provided at the bottom of pressure plate 308. The anti-slip texture increases the friction between pressure plate 308 and slide rail 302, thereby making slider 303 stably fixed on slide rail 302.

[0030] Example 2: Based on Example 1: The tensioning unit includes a mounting frame 401, a lower pressure roller 402, a threaded rod 403, a moving block 404, and an upper pressure roller 405. The mounting frame 401 is fixedly installed on the front and rear sides of the top of the panel 1. A rectangular groove is opened inside the mounting frame 401, and the width of the rectangular groove is equal to the width of the moving block 404. By rotating the two threaded rods 403 and the moving block 404, the moving block 404 drives the upper pressure roller 405 to move up and down along the rectangular groove, thereby adjusting the distance between the lower pressure roller 402 and the upper pressure roller 405, thereby adjusting the tension of the metal strip. The lower pressure roller 402 is installed at the lower end of the adjacent side of the two mounting frames 401. The threaded rod 403 is threadedly connected to the inside of the mounting frame 401. The moving block 404 is threadedly connected to the outside of the threaded rod 403. The upper pressure roller 405 is installed on the adjacent side of the two moving blocks 404.

[0031] Example 3: Based on Example 1: The measuring unit includes a pointer 501 and a scale 502. The pointer 501 is fixedly installed on the right side of the fixing block 306, and the scale 502 is fixedly installed on the top of the slide rail 302. The position of the slitting blade 305 is measured by the cooperation of the pointer 501 and the scale 502, thereby improving the slitting accuracy of the metal strip.

[0032] In use, push the slider 303 to slide along the slide rail 302, and measure the position between two adjacent sliders 303 using the pointer 501 and the scale 502 to make the distance between the two adjacent sliders 303 equal to the width of the metal strip to be cut. Pass the metal strip through the lower pressure roller 402 and the upper pressure roller 405, and then rotate the two threaded rods 403 to connect with the moving block 404. This causes the moving block 404 to drive the upper pressure roller 405 to move up and down along the rectangular groove to press the metal strip. Then, start the winding roller 2 to wind up the metal strip. When the metal strip moves to the right, the slitting knife 305 cuts the metal strip into strips.
