Technical Field
[0001] This utility model relates to the field of embossing and slitting machine technology, specifically a quick-change cutter for an embossing and slitting machine. Background Technology
[0002] A slitting machine is a mechanical device that cuts wide-width paper or film into multiple narrow strips. It is commonly used in papermaking and printing and packaging machinery. In the modern packaging industry, slitting machines are important equipment frequently used in pre-press and post-press processes. In pre-press, they are mainly used to cut raw materials such as paper and film.
[0003] For example, patent number CN206561679U discloses a multi-functional embossing and slitting machine, including a base. The lower surface of the base is provided with an adjustable height device. The upper surface of the base is sequentially provided with a raw material support frame, a feeding auxiliary support frame, an embossing support frame, a slitting support frame, and a discharge auxiliary support frame. The raw material support frame is provided with a raw material roller. The slitting support frame is provided with a placement plate. The placement plate is provided with multiple knife slots at equal intervals. The knife slots are provided with a driving device and a cutting knife connected to the driving device. The slitting support frame is provided with pressure rollers on both sides of the upper surface of the placement plate. The discharge auxiliary support frame is provided with a feeding roller. A winding roller is provided below the feeding roller.
[0004] However, the aforementioned patents still have some drawbacks in use. For example, the cutters in embossing slitting machines are mostly welded or bolted to the cutting rollers. When slitting different products, the cutters are not easy to replace, and sometimes the cutters are easily damaged when they are replaced. Therefore, different slitting machines are mostly used, which makes the cost higher. Utility Model Content
[0005] The purpose of this invention is to provide a quick-change cutter for an embossing slitting machine to solve the problems mentioned in the prior art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A quick-change cutter for an embossing slitting machine includes a cutting roller. A limiting groove is formed on the side wall of the cutting roller, and a fixing block is slidably disposed inside the limiting groove. The fixing block is fixedly disposed on the inner side wall of the cutter. An operating rod is disposed at the middle position of the cutting roller, and multiple mounting plates are disposed on the operating rod. Multiple first push blocks are fixedly disposed on each mounting plate, and a second push block is disposed at each of the first push blocks. A limiting rod is fixedly disposed on the second push block, and the end of the limiting rod away from the second push block passes through the cutting roller. Limiting holes are formed on the inner side walls of both the cutter and the fixing block, and positioning blocks are disposed at both ends of the fixing block on the inner side wall of the limiting groove.
[0008] In a preferred embodiment, the operating lever is threadedly connected to the inner wall of the cutting roller, and a knob is fixedly provided on one side of the operating lever located at the outer end of the cutting roller. The threaded connection between the operating lever and the inside of the cutting roller can prevent the operating lever from rotating after adjustment, while the knob facilitates the rotation of the operating lever.
[0009] In a preferred embodiment, the cutting roller has an annular limiting groove inside, the mounting plate is rotatably disposed in the annular limiting groove, the operating rod passes through the middle position of the mounting plate, and a protrusion is fixedly disposed on the outer side wall of the operating rod. A groove for the protrusion to slide is disposed on the middle side wall of the mounting plate. The annular limiting groove can prevent the mounting plate from moving with the operating rod, and only allow the mounting plate to rotate. When the operating rod rotates, the operating rod and the mounting plate move relative to each other.
[0010] In a preferred embodiment, the first push block and the second push block are both inclined on one side. A reset spring is fixedly provided on the second push block and the reset spring is sleeved on the outside of the limiting rod. The first push block can push the second push block to move outward, so that the second push block pushes the limiting rod out of the cutting roller and inserts it into the limiting hole.
[0011] In a preferred embodiment, one end of the positioning block is slidably disposed inside the side wall of the limiting groove, and a compression spring is fixedly disposed at one end of the positioning block. The positioning block can position the cutter in a fixed position and can also improve the stability of the cutter during use.
[0012] In a preferred embodiment, rubber pads are provided on the outer side of each positioning block, and at least three first push blocks are provided on each mounting plate. Three limit rods are also provided to ensure the stability of the cutter after installation.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model incorporates a limiting groove, a fixing block, an operating rod, a mounting plate, a push block, a limiting rod, a limiting hole, and an annular limiting groove. The cutter slides into the cutting roller through the fixing block. Then, by rotating the operating rod, the mounting plate on the operating rod rotates. When the mounting plate rotates, the first push block rotates and presses against the second push block, thereby causing the limiting rod on the second push block to push out of the cutting roller and into the limiting hole, thus fixing the cutter. This utility model can achieve the installation and disassembly of the cutter without the aid of other tools, making it convenient for processing different products.
[0015] 2. This utility model, by setting a positioning block and a compression spring, allows the positioning block to roughly position the cutter when it slides on the cutting roller. When the limiting rod is pushed outward, the position of the cutter can be manually fine-tuned so that all the limiting rods are inserted into the limiting holes, which facilitates the determination of the cutter position and thus improves the installation efficiency of the cutter.

[0021] 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.
[0022] Example: Please refer to Figures 1-4 This utility model provides a quick-change cutter for an embossing and slitting machine, the technical solution of which is as follows:
[0023] A quick-change cutter for an embossing slitting machine includes a cutting roller 1. A limiting groove 2 is formed on the side wall of the cutting roller 1. A fixing block 3 is slidably arranged inside the limiting groove 2. The fixing block 3 is fixedly arranged on the inner side wall of the cutter 4. An operating rod 5 is arranged at the middle position of the cutting roller 1. Multiple mounting plates 6 are arranged on the operating rod 5. Multiple first push blocks 7 are fixedly arranged on each mounting plate 6. A second push block 15 is arranged at each first push block 7. A limiting rod 8 is fixedly arranged on the second push block 15. The end of the limiting rod 8 away from the second push block 15 passes through the cutting roller 1. Limiting holes are formed on the inner side walls of the cutter 4 and the fixing block 3. Positioning blocks 10 are arranged at both ends of the fixing block 3 on the inner side wall of the limiting groove 2.
[0024] In a preferred embodiment, the operating lever 3 is threadedly connected to the inner wall of the cutting roller 1, and a knob 11 is fixedly installed on one side of the operating lever 3 at the outer end of the cutting roller 1. An annular limiting groove 12 is formed inside the cutting roller 1, and the mounting plate 6 is rotatably disposed within the annular limiting groove 12. The operating lever 5 passes through the middle position of the mounting plate 6, and a protrusion 13 is fixedly installed on the outer wall of the operating lever 5. A groove 14 for sliding the protrusion 13 is formed on the middle side wall of the mounting plate 6.
[0025] When the operating lever 3 is rotated by the knob 11, the end of the operating lever 3 is connected to the inside of the cutting roller 1 by a thread, so the operating lever 3 can move inside the cutting roller 1. When the operating lever 3 moves, the mounting plate 6 cannot move under the restriction of the annular limiting groove 12. Moreover, the operating lever 5 and the mounting plate 6 are connected by a protrusion 13 and a groove 14 structure, so the mounting plate 6 can rotate under the action of the protrusion 13, and the protrusion 13 moves along the groove 14.
[0026] In a preferred embodiment, the first push block 7 and the second push block 15 are both inclined on their adjacent sides. A reset spring 16 is fixedly provided on the second push block 15, and the reset spring 16 is sleeved on the outside of the limiting rod 8. When the first push block 7 approaches the second push block 15, it can push the second push block 15 to move outward, thereby causing the second push block 15 to drive the limiting rod 8 to move outward, so that the limiting rod 8 is inserted into the limiting hole on the cutter 4 and the fixing block 3. The reset spring 16 can reset the second push block 15.
[0027] In a preferred embodiment, one end of the positioning block 10 is slidably disposed inside the side wall of the limiting groove 2, and a compression spring 17 is fixedly disposed at one end of the positioning block 10. The positioning block 10 can retract and squeeze the compression spring 9 towards the inside of the limiting groove 2, and the compression spring 9 can also pop the positioning block 10 out to limit the fixed block.
[0028] In a preferred embodiment, rubber pads are provided on the outer side of each positioning block 10, and at least three first push blocks 7 are provided on each mounting plate 6.
[0029] The working principle of this utility model:
[0030] When installing the cutter, insert the fixing block 3 on the cutter 4 into the limiting groove 2 on the cutting roller 1. Two sets of limiting grooves 2 and fixing blocks 3 can be provided for easy positioning. The fixing block 3 slides along the limiting groove 2. When the fixing block 3 slides to the positioning block 10, push the positioning block 10 into the side wall of the limiting groove 2, allowing the fixing block 3 to continue sliding past the positioning block 10. When the fixing block 3 slides to the appropriate position of the positioning block 10, push the first positioning block 10 into the side wall of the limiting groove 2, then push the fixing block 3 between the two positioning blocks 10. Use the compression spring 9 to pop out the pushed-in positioning block 10. Positioning block 10 positions fixing block 3, and then rotating knob 11 causes operating rod 5 to rotate. When operating rod 5 rotates, it drives mounting plate 6 to rotate, causing first push block 7 on mounting plate 6 to move closer to second push block 15. As first push block 7 rotates continuously, second push block 15 is pushed outward, causing limiting rod 8 on second push block 15 to extend out of the surface of cutting roller 1. Limiting rod 8 is inserted into limiting hole on inner wall of cutter 4 and fixing block 3, thus fixing cutter. Moreover, since operating rod 5 is internally threaded to cutting roller 1, no additional positioning component is needed for operating rod 5.
[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
