Abstract
Description
Technical Field
[0001] This utility model relates to the field of parts spraying technology, and in particular to a novel longitudinal slitting unit. Background Technology
[0002] In modern industrial production, slitting lines are key equipment in material processing and are widely used in many fields such as metal processing, electronic material manufacturing, and packaging material production. As various industries continue to increase their requirements for the precision and quality of material processing, more stringent standards are being placed on the performance of slitting lines.
[0003] Existing slitting machines mainly consist of core components such as an uncoiling mechanism, a slitting mechanism, a slitting guide mechanism, and a winding mechanism in terms of mechanical structure and technical principles. The uncoiling mechanism is responsible for smoothly unwinding the coiled raw material, ensuring stable tension during unwinding through motor drive and tension control devices. The slitting mechanism, as a core component, typically uses upper and lower cutters in cooperation, achieving longitudinal slitting of the material through high-speed rotation and precise feeding of the cutters. The slitting guide mechanism guides the slit material smoothly into the winding mechanism, preventing deviation or stacking. The winding mechanism rewinds the slit material into coils, ensuring neatness and tightness of the winding through a tension control system.
[0004] However, existing slitting units have significant shortcomings in material cleaning. Before slitting, dust, impurities, and other foreign matter often adhere to the material surface. Due to the lack of effective cleaning methods, these dust and impurities easily enter the gap between the cutting tool and the material. During the slitting process, dust and impurities act like abrasive particles, intensifying the friction between the cutting tool and the material. On the one hand, this friction can lead to defects such as scratches and pits on the material surface, seriously affecting the material's appearance quality and subsequent processing performance; on the other hand, frequent friction accelerates tool wear, shortens tool life, and increases tool replacement frequency and costs. Furthermore, the reduced slitting accuracy caused by tool wear also results in material waste and reduced production efficiency, causing significant economic losses to enterprises. Therefore, a new type of slitting unit is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a new type of slitting machine unit, which aims to improve the problem that the existing technology cannot clean the material surface.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A novel slitting machine unit includes a table, a cleaning component on the top of the table, a replacement component on the top of the table, and a blade on the top of the table;
[0008] The cleaning assembly includes two cleaning brushes, the outer walls of which are disposed on the top of the countertop. A side plate is rotatably connected to the outer wall of one of the cleaning brushes. The bottom of the side plate is fixedly connected to the top of the countertop. A fan is fixedly connected to the outer wall of the side plate. A sliding block is disposed inside the side plate. A sliding groove is formed inside the side plate. The outer wall of the sliding block is slidably connected to the inner wall of the sliding groove. The inner wall of the sliding block is rotatably connected to the outer wall of the other cleaning brush. A spring is disposed inside the side plate. One end of the spring is fixedly connected to the top of the sliding block, and the other end of the spring is fixedly connected to the inner wall of the side plate.
[0009] As a further description of the above technical solution:
[0010] The replacement component includes a slide rail and a fixing plate. The bottom of the slide rail is fixedly connected to the top of the tabletop, and the fixing plate is disposed on the top of the tabletop.
[0011] As a further description of the above technical solution:
[0012] A support frame is fixedly connected to the top of the tabletop, an electric push rod is fixedly connected to the top of the support frame, and a fixed plate is fixedly connected to the output end of the electric push rod.
[0013] As a further description of the above technical solution:
[0014] One of the fixing plates is slidably connected to the top of the slide rail, and the other fixing plate is fixedly connected to the top of the table surface;
[0015] As a further description of the above technical solution:
[0016] Both of the fixed plates have support blocks fixedly connected to their outer walls, and each support block has a sliding groove inside.
[0017] As a further description of the above technical solution:
[0018] The two fixed plates are equipped with rotating columns inside, and the outer walls of the rotating columns are fixedly connected to the inner walls of the cutter. Bearings are also fixedly connected to the outer walls of the rotating columns.
[0019] As a further description of the above technical solution:
[0020] A limiting block is fixedly connected to the outer wall of the bearing, and the outer wall of the limiting block is slidably connected to the inner wall of the sliding groove.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, a blower is used to clean the material before slitting, and then the spring rebound drives the cleaning brush, achieving the effect of cleaning materials of different specifications before slitting. This prevents dust and impurities from entering the gap between the blade and the material, forming abrasive particles during the slitting process, which would cause scratches, pits and other defects on the material surface. This keeps the material surface clean, reduces the wear of the blade on the dust and impurities, and prevents the material from being scratched or damaged by dust and impurities during the slitting process. At the same time, it extends the blade replacement cycle and reduces blade costs.
[0023] 2. In this utility model, the distance between the moving plate and the fixed plate is adjusted by an electric push rod, and then the tool is disassembled by moving out of the sliding groove II through the limit block. This achieves the adaptation to different specifications of tools. At the same time, the tools can be arranged in advance, avoiding the complex disassembly and installation process involved in replacing fixed tools when they need to be replaced. This process takes a long time to complete, which will cause the equipment to be unable to operate for a long time and affect the production progress. It also avoids the problem of only being able to use a single specification of tool. When there is a need for slitting materials of different specifications, the company will have to purchase new equipment. This allows for the rapid replacement of tools. According to the specific production needs, the appropriate tool can be quickly replaced, reducing the downtime of the equipment due to tool replacement and enabling more continuous production.

[0031] 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.
[0032] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a novel longitudinal slitting machine unit, comprising a table 1, characterized in that: a cleaning component is provided on the top of the table 1, a replacement component is provided on the top of the table 1, and a blade 3 is provided on the top of the table 1. The existing blade 3 is usually composed of components such as a blade body, a blade edge, a blade shaft, and a positioning device, and is used to longitudinally slit materials. This is the prior art and will not be described in detail here.
[0033] The cleaning assembly includes two cleaning brushes 6, which are used to clean both sides of the material, thereby preventing dust from entering the blade 3, reducing wear on the blade 3, and lowering maintenance costs. The outer walls of the two cleaning brushes 6 are set on the top of the work surface 1. A side plate 4 is rotatably connected to the outer wall of one cleaning brush 6. The bottom of the side plate 4 is fixedly connected to the top of the work surface 1. A fan 5 is fixedly connected to the outer wall of the side plate 4. The fan 5 is used for preliminary cleaning of the material, thereby preventing the cleaning brushes 6 from failing to completely remove impurities from the material surface, increasing cleaning efficiency, and ensuring that dust is completely removed. A sliding block 7 is provided inside the side plate 4, and a sliding groove is formed inside the side plate 4. 8. The outer wall of the sliding block 7 is slidably connected to the inner wall of the sliding groove 8. The inner wall of the sliding block 7 is rotatably connected to the outer wall of another cleaning brush 6. The sliding block 7 slides inside the sliding groove 8, thereby adapting to materials of different specifications and preventing excessively thick materials from failing to pass through the cleaning brush 6, thus enhancing the versatility of the equipment. A spring 9 is installed inside the side plate 4. One end of the spring 9 is fixedly connected to the top of the sliding block 7, and the other end of the spring 9 is fixedly connected to the inner wall of the side plate 4. The spring 9 is used to apply downward pressure to the sliding block 7, thereby increasing the friction between the cleaning brush 6 and the material, avoiding incomplete cleaning of impurities on the material surface, and increasing the cleaning effect.
[0034] Reference Figure 1 and Figures 3-5The replacement components include a slide rail 10 and a fixing plate 17. The bottom of the slide rail 10 is fixedly connected to the top of the tabletop 1. The fixing plate 17 is located on the top of the tabletop 1. A support frame 11 is fixedly connected to the top of the tabletop 1. An electric push rod 12 is fixedly connected to the top of the support frame 11. The output end of the electric push rod 12 is fixedly connected to a fixing plate 17. The bottom of one fixing plate 17 is slidably connected to the top of the slide rail 10. The electric push rod 12 moves parallel to the fixing plate 17, thereby releasing the fixation of the tool 3 and achieving the effect of replacing the tool 3. The other fixing plate 17 is fixedly connected to the top of the tabletop 1. Support blocks 15 are fixedly connected to the outer walls of both fixing plates 17. The support blocks 15 are used to support the tool 3 when it is removed, thereby preventing the tool from slipping. The tool 3 is designed to be easy to replace, reducing the difficulty of replacement. The support block 15 has a sliding groove 16 inside, and the two fixing plates 17 have rotating columns 2 inside. The outer wall of the rotating column 2 is fixedly connected to the inner wall of the tool 3. The outer wall of the rotating column 2 is fixedly connected to the bearing 13. The bearing 13 is used to fix the rotating column 2 without affecting its rotation, thereby preventing the tool 3 from being unable to perform longitudinal slitting work properly after installation, ensuring the normal operation of the workflow. The outer wall of the bearing 13 is fixedly connected to the limit block 14. The outer wall of the limit block 14 is slidably connected to the inner wall of the sliding groove 16. The limit block 14 works with the sliding groove 16 to limit the tool 3, preventing the tool 3 from falling off when the fixing plate 17 moves, reducing the difficulty of replacement and reducing safety hazards during replacement.
[0035] Working principle: Before longitudinal slitting, the blower 5 first removes impurities from the surface of the material. The cleaning brush 6 removes impurities that the blower 5 cannot completely remove from the upper and lower surfaces of the material. Then, the sliding block 7 drives the cleaning brush 6 to move. The sliding block 7 then drives the spring 9 to compress. The spring 9 then rebounds and drives the sliding block 7, keeping the cleaning brush 6 always on the surface of the material to be cleaned. This achieves cleaning of materials of different thicknesses and avoids damage to the cutting tool 3 and the material surface caused by dust and impurities.
[0036] When the tool 3 needs to be disassembled, firstly, the electric push rod 12 is activated, which drives the fixed plate 17 to move. Then, the movement of the fixed plate 17 drives the support block 15 to move. The limiting block 14 limits the sliding groove 16 to prevent the tool 3 from falling off when the fixed plate 17 moves. Next, the tool 3 is removed upward by the movement of the fixed plate 17. When the tool 3 is installed, simply place the limiting block 14 into the sliding groove 16, and then activate the electric push rod 12 to push the fixed plate 17. When the rotating column 2 moves into the fixed plate 17, the tool 3 is fixed, achieving quick disassembly of the tool 3. At the same time, different specifications of tools 3 can be replaced, increasing the versatility of the equipment.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
