[0006] To achieve the above objectives, this utility model provides the following technical solution: a slitting knife guide mechanism for a slitting machine, comprising a base and a slitting knife assembly, the slitting knife assembly being disposed on one side of the base, and U-shaped baffles being provided on both sides of the top of the base, with an adjustment structure and a pushing structure on one side of each U-shaped baffle, a U-shaped mounting groove being formed on the inner side of each U-shaped baffle, a rotating shaft being rotatably connected inside the U-shaped mounting groove, a worm gear being fixedly connected to the outer side of the rotating shaft, a worm being meshed with the outer side of the worm gear, gears being fixedly connected to the outer sides of both ends of the rotating shaft, racks being meshed with the outer sides of both gears, both racks being slidably connected to the U-shaped baffles, and inserts being fixedly connected to one end of each rack, T-shaped grooves being formed at the top and bottom of the inner side of each U-shaped baffle, one end of each insert passing through the inner side of the U-shaped mounting groove and extending into the two T-shaped grooves, the inserts being slidably connected to the U-shaped baffles, and a guide structure being provided between the two inserts.

[0007] Preferably, the adjustment structure includes a U-shaped baffle one, which is slidably connected to the outside of a U-shaped baffle two. One side of the U-shaped baffle one is provided with an internally threaded cylinder, which passes through the outside of the U-shaped baffle one and is rotatably connected to it. A worm gear one is fixedly connected to the outside of the internally threaded cylinder, and a worm is meshed with the outside of the worm gear one. Support blocks are rotatably connected to both ends of the worm gear one, and both support blocks are fixedly connected to the U-shaped baffle one. A throttle handle one is installed at one end of the worm gear one. The two support blocks provide rotational support for the worm gear one.

[0008] Preferably, the adjustment structure further includes a threaded rod and two limiting rods. The threaded rod is threadedly connected to the inside of the internal threaded cylinder. One end of the threaded rod is fixedly connected to the second U-shaped baffle. Both limiting rods are fixedly connected to one side of the second U-shaped baffle. One end of each limiting rod passes through the inner side of the first U-shaped baffle and is slidably connected to the first U-shaped baffle.

[0009] Preferably, the pushing structure includes a hydraulic cylinder, which is disposed on one side of a U-shaped baffle. The telescopic end of the hydraulic cylinder is fixedly connected to the U-shaped baffle. A protruding plate is fixedly connected to the outside of the hydraulic cylinder, and the protruding plate is fixedly connected to the outside of the base.

[0010] Preferably, the base has four convex grooves on its top, and two convex blocks are fixedly connected to the bottom of each of the two U-shaped baffles. The convex blocks are disposed inside the convex grooves and are slidably connected to the base. The arrangement of the convex blocks and convex grooves can improve the stability of the movement of the U-shaped baffles.

[0011] Preferably, the outer sides of the two U-shaped baffles and the two U-shaped baffles are provided with round holes, and the multiple round holes correspond to each other. A threaded rod is provided between the two convex plates, and the threaded rod passes through the multiple round holes in sequence. The two ends of the threaded rod are rotatably connected to the two convex plates respectively.

[0012] Preferably, one end of the worm gear is rotatably connected to the U-shaped baffle, and the other end of the worm gear passes through the inner side of the U-shaped mounting groove and is rotatably connected to the U-shaped baffle. A throttle handle is installed on one end of the worm gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application utilizes the meshing of gears and racks. The movement of the rack causes the insert block to move accordingly, moving it into the U-shaped mounting groove. The insert block then moves out of the fixed slot on the outside of the T-shaped block, thereby releasing the T-shaped block from its limit. After the limit is released, the operator can pull the two T-shaped blocks out of the two T-shaped slots, thus completing the disassembly of the side roller and facilitating its replacement. Through the above steps, the anti-deviation slitting knife guide mechanism for slitting machines can conveniently and quickly disassemble and replace the side roller, effectively solving the problem of inconvenient side roller disassembly in the prior art.

[0016] 2. This application utilizes a worm gear and a worm wheel to mesh. The rotation of the worm gear drives the worm wheel to rotate, which in turn rotates the internal threaded cylinder. The internal threaded cylinder is threadedly connected to the threaded rod. Under the limiting action of two limit rods, the rotation of the internal threaded cylinder causes the threaded rod to move along the axial direction of the internal threaded cylinder, thereby driving the U-shaped baffle to move. The movement of the U-shaped baffle can realize the position adjustment of multiple side rollers, facilitating the adjustment of material entering the guide groove. This structure, with its worm gear and worm wheel, has a certain self-locking function, ensuring that the position of the U-shaped baffle can be stably maintained during the adjustment process and will not easily shift due to external forces, thus ensuring the accuracy of material guidance.

[0023] 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.

[0024] Example: Figure 1 - Figure 5 As shown, this utility model provides a technical solution for an anti-deviation slitting knife guide mechanism for a slitting machine, including a base 1 and a slitting knife assembly 2. The slitting knife assembly 2 is disposed on one side of the base 1. U-shaped baffles 2 and 6 are provided on both sides of the top of the base 1. An adjustment structure and a pushing structure are provided on one side of each U-shaped baffle 2 and 6. A U-shaped mounting groove 16 is formed inside the U-shaped baffle 2 and 16. A rotating shaft 17 is rotatably connected inside the U-shaped mounting groove 16. A worm gear 2 and 18 are fixedly connected to the outside of the rotating shaft 17. A worm 2 and 19 are meshed on the outside of the worm gear 2 and 18. One end of the worm 2 and 19 is rotatably connected to the U-shaped baffle 2 and 16, and the other end of the worm 2 and 19 passes through the U-shaped baffle 2 and 16. The inner side of the mounting groove 16 is rotatably connected to the U-shaped baffle 2 6. One end of the worm gear 2 19 is equipped with a throttle 2. Gears 20 are fixedly connected to the outer sides of both ends of the rotating shaft 17. The outer sides of the two gears 20 are meshed with racks 21. The two racks 21 are slidably connected to the U-shaped baffle 2 6. One end of the two racks 21 is fixedly connected to an insert block 210. T-shaped grooves 13 are opened at the top and bottom of the inner side of the U-shaped baffle 2 6. One end of the two insert blocks 210 passes through the inner side of the U-shaped mounting groove 16 and extends into the two T-shaped grooves 13. The insert blocks 210 are slidably connected to the U-shaped baffle 2 6. A guide structure is provided between the two insert blocks 210.

[0025] The guide structure has two T-shaped blocks 14, which are respectively set inside two T-shaped grooves 13. The outer sides of the two T-shaped blocks 14 are provided with fixed slots 140. Two inserts 210 are respectively set inside the two fixed slots 140. Multiple side rollers 15 are rotatably connected between the two T-shaped blocks 14. Multiple guide grooves are provided on the outer sides of the side rollers 15.

[0026] Specifically, the operator first rotates the second throttle, which drives the second worm gear 19 to rotate. Since the second worm gear 19 meshes with the second worm wheel 18, the second worm wheel 18 rotates accordingly. The rotation of the second worm wheel 18 causes the rotating shaft 17, which is fixedly connected to it, to rotate inside the U-shaped mounting groove 16. The rotating shaft 17 drives the two gears 20 to rotate. The gears 20 mesh with the rack 21. The movement of the rack 21 causes the insert block 210 to move accordingly. The insert block 210 moves into the U-shaped mounting groove 16 and moves out of the fixed slot 140 on the outside of the T-shaped block 14, thereby releasing the T-shaped block 14 from its limit. After the limit is released, the operator can pull the two T-shaped blocks 14 out of the two T-shaped grooves 13, thus completing the disassembly of the side roller 15 and facilitating its replacement. Through the above steps, the anti-deviation slitting knife guide mechanism of the slitting machine can conveniently and quickly disassemble and replace the side roller 15, effectively solving the problem of inconvenient disassembly of the side roller 15 in the prior art.

[0027] Example: Figure 1 - Figure 3 As shown, the adjustment structure includes a U-shaped baffle 4, which is slidably connected to the outside of a U-shaped baffle 6. An internally threaded cylinder 9 is provided on one side of the U-shaped baffle 4, passing through the outside of the U-shaped baffle 4 and rotatably connected to it. A worm gear 10 is fixedly connected to the outside of the internally threaded cylinder 9, and a worm 11 is meshed with the outside of the worm gear 10. Support blocks are rotatably connected to both ends of the worm 11, and both support blocks are fixedly connected to the U-shaped baffle 4. A throttle handle is installed at one end of the worm 11. The adjustment structure also includes a threaded rod 8 and two limiting rods 12. The threaded rod 8 is threadedly connected to the inside of the internally threaded cylinder 9, and one end of the threaded rod 8 is fixedly connected to the U-shaped baffle 6. Both limiting rods 12 are fixedly connected to one side of the U-shaped baffle 6, and one end of each limiting rod 12 passes through the inside of the U-shaped baffle 4 and is slidably connected to it.

[0028] The pushing structure includes a hydraulic cylinder 5, which is located on one side of the U-shaped baffle 4. The telescopic end of the hydraulic cylinder 5 is fixedly connected to the U-shaped baffle 4. A convex plate 3 is fixedly connected to the outside of the hydraulic cylinder 5. The convex plate 3 is fixedly connected to the outside of the base 1. The top of the base 1 has four convex grooves 100. The bottom of the two U-shaped baffles 4 is fixedly connected to two convex blocks 400. The convex blocks 400 are located inside the convex grooves 100 and are slidably connected to the base 1. The two U-shaped baffles 6 and the two U-shaped baffles 4 are all provided with round holes 7 on their outer sides. The multiple round holes 7 correspond to each other. A threaded rod 8 is provided between the two convex plates 3. The threaded rod 8 passes through the multiple round holes 7 in sequence. The two ends of the threaded rod 8 are rotatably connected to the two convex plates 3 respectively.

[0029] Specifically, the two hydraulic cylinders 5 are activated, and the extension and retraction of the hydraulic cylinders 5 can adjust the position of the U-shaped baffle 4. The four convex blocks 400 slide in the four convex grooves 100 respectively, thereby adjusting the relative position of the two U-shaped baffles 4.

[0030] When the operator turns the first throttle, the worm gear 11 meshes with the worm wheel 10. The rotation of the worm gear 11 drives the worm wheel 10 to rotate, and the internal threaded cylinder 9 rotates accordingly. The internal threaded cylinder 9 is threadedly connected to the threaded rod 8. Under the limiting action of the two limit rods 12, the rotation of the internal threaded cylinder 9 causes the threaded rod 8 to move along the axial direction of the internal threaded cylinder 9, thereby driving the U-shaped baffle 2 6 to move. The movement of the U-shaped baffle 2 6 can realize the position adjustment of multiple side rollers 15, which facilitates the adjustment of the material entering the guide groove. This structure is equipped with worm gear 11 and worm wheel 10, which has a certain self-locking function, which can ensure that the position of the U-shaped baffle 2 6 can be stably maintained during the adjustment process, and will not easily be displaced due to external force, thereby ensuring the accuracy of material guidance.

[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.
