Description

Technical Field

[0001] This utility model relates to the field of abrasive belt processing equipment, and in particular to an abrasive belt slitting machine. Background Technology

[0002] In the field of abrasive belt production and processing, the abrasive belt slitting machine is one of the core pieces of equipment for achieving large-scale and precise abrasive belt production. Its main function is to slit large-format abrasive belt master rolls into finished abrasive belts of different widths and specifications according to actual production needs. These are widely used in surface treatment processes in various industries such as hardware processing, wood sanding, and automobile manufacturing. As downstream industries continuously increase their requirements for the precision and production efficiency of abrasive belt products, the performance stability, ease of maintenance, and cost control capabilities of the abrasive belt slitting machine have become key factors affecting the competitiveness of abrasive belt manufacturers. Among these, the cutting blade, as the core component that directly contacts the abrasive belt for slitting operations, plays a crucial role in the overall operational efficiency of the equipment through its use and maintenance.

[0003] Existing belt slitting machines typically employ an integrated cutting mechanism. Their technical principle involves utilizing the relative motion between the sharp blade and the belt master roll to slit the belt. To ensure slitting accuracy, the drive roller and cutting blade must maintain a high degree of coaxiality and stability. Therefore, during assembly, strict precision calibration of the connection between the blade and the drive roller is necessary to ensure that the blade does not deviate or wobble during high-speed operation, thus meeting the dimensional requirements for belt slitting.

[0004] However, the cutting mechanism of existing belt sander has certain defects in actual use: when a single cutting blade is damaged due to long-term wear, accidental collision, or other reasons and can no longer work normally, because the blade and the drive roller adopt an integrated fixed structure, the operator cannot disassemble and replace the damaged blade separately. Instead, the entire drive roller, along with the other undamaged blades on it, must be removed from the equipment and disposed of. This not only results in a large number of intact blades being wasted, increasing the consumable costs in the belt sander production process, but also prolongs the equipment downtime for maintenance due to the complex and time-consuming process of replacing the entire drive roller, thus reducing the overall efficiency of the belt sander. Therefore, a belt sander is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a belt slitting machine, which aims to improve the problem in the prior art where the transmission roller and the intact blade must be discarded together when a single blade is damaged.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A belt slitting machine includes a belt slitting machine, a roller rotatably connected to the inner wall of the belt slitting machine, a drive roller and an adjusting roller sequentially arranged on one side of the roller, an adaptive component provided on the outer wall of the adjusting roller, a clamping block one and a clamping block two fixedly connected to both ends of the roller, the clamping block one and the clamping block two fitting against both ends of the drive roller, a plurality of screws threadedly connected to the outer wall of each clamping block one and the clamping block two, a plurality of cutting blades slidably connected to the outer wall of the drive roller, and a replacement component provided on the outer wall of each cutting blade;

[0013] As a further description of the above technical solution:

[0014] Each of the connecting discs is fixedly connected to one end of the connecting post on one side, each of the connecting posts has a groove on its outer side wall, and each of the connecting shells has a fixed disc fixedly connected to one end.

[0015] As a further description of the above technical solution:

[0016] Multiple ball bearings are slidably connected inside the clamping block 1, and the multiple ball bearings engage with the internal grooves of the transmission roller.

[0017] As a further description of the above technical solution:

[0034] 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.

[0035] Reference Figures 1-4This utility model provides an embodiment of a belt slitting machine, including a belt slitting machine 1. When using the belt slitting machine 1, the entire roll of abrasive belt material is first fixed and unwound. After the guide mechanism calibrates the position, the slitting blade cuts the belt to a set width. The cut abrasive belt strips are then neatly wound up by a winding mechanism to complete the slitting operation. This is prior art and will not be described in detail. A roller 2 is rotatably connected to the inner wall of the belt slitting machine 1. This roller 2 is typically made of 45# steel and provides basic rotational power for conveying and cutting the abrasive belt. A drive roller 3 and an adjusting roller 5 are sequentially arranged on one side of the roller 2. The drive roller 3 is used to install and drive the cutting blade 4 to rotate, thereby achieving precise slitting of the abrasive belt. The adjusting roller 5, in conjunction with an adaptive component, performs reciprocating motion to achieve dynamic adjustment. To improve the tension of the abrasive belt, the outer wall of the adjusting roller 5 is equipped with an adaptive component. This adaptive component is used to buffer and compensate for fluctuations in the tension of the abrasive belt to maintain the stability of the tension. Both ends of the roller 2 are fixedly connected with clamping blocks 1 6 and 2 7, which are in contact with both ends of the transmission roller 3. These two structures are used to axially position and radially clamp the transmission roller 3 to ensure its rotational stability. Each clamping block 1 6 and clamping block 2 7 has multiple high-strength 12.9 grade screws threadedly connected to its outer wall. Multiple cutting blades 4 made of hard alloy or high-speed steel are slidably connected to the outer wall of the transmission roller 3. Each cutting blade 4 has a replacement component on its outer wall. This replacement component is used to realize the quick disassembly and installation of a single cutting blade 4, which greatly improves maintenance efficiency and reduces replacement costs.

[0036] Each replacement assembly includes multiple retaining balls 13 made of GCr15 bearing steel, located on one side of the cutting blade 4. A connecting ring 22 is fixedly connected to one side of each cutting blade 4. This connecting ring 22 integrates the cutting blade 4 with other parts of the replacement assembly, forming a detachable module. A connecting shell 23 is slidably connected inside each connecting ring 22. One end of each connecting shell 23 passes through the connecting ring 22 and extends into the interior of the transmission roller 3. A pushing assembly is provided on the outer wall of each retaining ball 13. This pushing assembly transmits manual pressing operations, driving the internal mechanism to unlock. The pushing assembly includes multiple connecting posts 12, which fit against the outer wall of the retaining balls 13. A fixing ring 8 is fixedly connected to the top of the inner wall of each connecting shell 23. A transmission bar 25 is slidably connected to the inner wall of each fixing ring 8. One end of each transmission bar 25 is fixedly connected to... A pressing plate 24 is fixedly connected to each of the transmission bars 25. The pressing plate 24 serves as an operating interface for applying manual force to unlock the replacement component. A connecting plate 11 is fixedly connected to the other end of each transmission bar 25. Each connecting plate 11 is slidably connected to the inner wall of the clamping block 6. One side of each connecting plate 11 is fixedly connected to one end of a connecting post 12. A groove 14 is provided on the outer wall of each connecting post 12. The groove 14 is used to provide a receiving space when unlocking, allowing the locking ball 13 to disengage from the locked state with the transmission roller 3. A fixing plate 9 is fixedly connected to one end of each connecting shell 23. Multiple locking balls 13 are slidably connected inside the clamping block 6. The locking balls 13 cooperate with the slots inside the transmission roller 3 to perform radial extension and retraction movements, achieving the effect of locking or releasing the cutting blade 4 component. Multiple locking balls 13 are slidably connected inside the clamping block 6, and multiple locking balls 13 are engaged with the slots inside the transmission roller 3.

[0037] Reference Figure 1 , Figure 5 and Figure 6The adaptive component includes multiple springs 18 made of 65Mn spring steel, located at both ends of the adjusting roller 5. These springs 18 provide core rebound force, enabling dynamic adaptive adjustment of the abrasive belt tension. Fixed housings 15, welded from Q235 carbon steel plates, are fixedly connected to both sides of the inner wall of the abrasive belt slitter 1. Each fixed housing 15 has a connecting block 16 and multiple sliding plates 21 with a polytetrafluoroethylene wear-resistant layer slidably connected to its inner wall. The sliding plates 21, in conjunction with the connecting block 16, slide linearly on the inner wall of the fixed housing 15 with low friction, achieving precise transmission of the displacement of the adjusting roller 5 to the inner wall. The effect of spring 21 is that multiple sliding plates 21 are fixedly connected to the outer walls of the connecting blocks 16 on both sides. Multiple fixing blocks 20 are fixedly connected to the top of each connecting block 16 and the top of the inner wall of the fixing shell 15. A connecting strip 19 is fixedly connected to one side of each fixing block 20. The connecting strip 19 serves as the guide rod and fixed fulcrum of the spring, which is used to ensure that spring 218 can be stably compressed and stretched when subjected to force. A baffle 17 is fixedly connected to one end of each connecting strip 19. The baffle 17 is used to provide a reliable mounting base and force endpoint for spring 218. The two ends of spring 21 are sleeved on the surface of the connecting strips 19 on both sides.

[0038] Working principle: During the adaptive adjustment of the surface tension of the sanding belt, the elasticity of spring 18 is used to reduce the slight vibration of the sanding belt on the surface of the adjusting roller 5 during the cutting process. At the same time, the sanding belt is stretched during slitting, which increases the tension. This causes the connecting block 16 and the sliding plate 21 to slide on the inner wall of the fixed shell 15 through the adjusting roller 5, causing spring 18 to contract and thus relieve some of the tension. If the tension decreases, the spring will stretch again according to the same principle to supplement a certain amount of tension, maintain the stability of the sanding belt tension, ensure the accuracy of the slitting size, and reduce quality problems such as inconsistent slitting width of the sanding belt caused by unstable tension.

[0039] During the disassembly and replacement of the cutting blade 4, according to existing technology, the screws on the surfaces of clamping blocks 1 6 and 2 7 are unscrewed, and the transmission roller 3 is pulled out from the inner wall of clamping blocks 1 6 and 2 7. Next, the pressing plate 24 is pressed, and the connecting column 12 is moved down through the transmission bar 25 until the groove 14 and the retaining ball 13 are at the same height. During this process, the connecting plate 11 will push the spring 10 to be stretched. Next, the fixing plate 9 is pulled up to move clamping block 1 6 out of the transmission roller 3 and the connecting ring 22. The inner surface of the transmission roller 3 pushes the retaining ball 13 into clamping block 1 6. The movement of the part causes the locking ball 13 to fit against the inner wall of the groove 14, thus allowing the clamping block 6 to be pulled out from inside the transmission roller 3 and the connecting ring 22. This allows the cutting blade 4 and the connecting ring 22 to be removed from the surface of the transmission roller 3. Then, another cutting blade 4 is fixed to the outer wall of the transmission roller 3 in the same way, so that multiple locking balls 13 engage with the internal locking grooves of the transmission roller 3, thereby fixing the cutting blade 4. This achieves a good replacement effect for the cutting blade 4 and avoids the situation where the transmission roller 3 and all the remaining cutting blades 4 are discarded due to the damage of a single cutting blade 4.
