[0001] This utility model relates to the field of cutting equipment technology, and in particular to a quick-change saw blade saw. Background Technology

[0002] As a crucial piece of equipment in modern metal processing, the development level of a quick-change saw blade saw directly impacts industrial production efficiency and processing quality. With the manufacturing industry moving towards intelligent and efficient operations, traditional saw blades are increasingly unable to meet modern production demands in terms of saw blade replacement efficiency and ease of operation. This is especially true when processing materials of different specifications in batches, where the need for frequent saw blade changes is becoming increasingly prominent, placing higher demands on the quick-change function of the saw blade.

[0003] In existing technologies, saw blades on banding machines are typically secured using bolts or keyway connections. Bolt securing requires the use of wrenches and other tools to tighten or loosen multiple bolts, while keyway connections require precise alignment and hammering for installation. Both methods demand a certain level of professional skill from the operator, and auxiliary tools are often needed during replacement. Regarding the cooling system, traditional banding machines often employ open cooling or simple filtration designs, making the coolant susceptible to contamination and requiring frequent replacements.

[0004] However, the existing saw blade replacement process is cumbersome and time-consuming, which can easily affect production efficiency. Especially in working conditions where frequent saw blade replacement is required, traditional fixing methods are not only complicated to operate, but also make it difficult to guarantee the concentricity and stability of the saw blade after each installation, which can easily lead to decreased processing accuracy and safety accidents. This problem has become a major bottleneck restricting the improvement of sawing machine efficiency. Utility Model Content

[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] Reference Figures 1-4 The present invention provides an embodiment of a quick-change saw blade saw, including a workbench 1, which provides overall support and installation foundation for the saw. A grid 2 is fixedly connected to the inner wall of the workbench 1 to filter and recover coolant and intercept larger debris. A fixing plate 3 is fixedly connected to the upper surface of the workbench 1 to support and fix a motor 6 and related components. A support plate 5 is fixedly connected to the outer wall of the fixing plate 3 to provide an installation platform for the motor 6. A connecting plate 4 is fixedly connected to the outer wall of the fixing plate 3. The motor 6 is fixedly connected to the upper surface of the support plate 5 to provide rotational power for the saw blade 16. A connecting shaft 7 is fixedly connected to the output end of the motor 6 to transmit power and has a built-in disassembly and assembly mechanism. The connecting shaft 7 is equipped with disassembly and assembly components inside.

[0027] The assembly and disassembly components include a locking block 13, which quickly fixes the saw blade 16 by engaging. The outer wall of the locking block 13 is slidably connected to the inner wall of the connecting shaft 1 7. The inner wall of the locking block 13 is rotatably connected to a connecting rod 12, which converts linear motion into radial motion of the locking block 13. The outer wall of the connecting rod 12 is rotatably connected to a rotating disk 11, which supports the threaded rod 10 and provides threaded engagement. The rotating disk 11 is internally threaded with the threaded rod 10, which converts rotational motion into linear motion. The outer wall of the threaded rod 10 is fixedly connected to a rotating ring 9. The outer wall of the rotating ring 9 is fitted with a connecting shaft 2 8, which connects to the saw blade 16 and is detachable. The outer wall of the connecting shaft 2 8 is fixedly connected to the saw blade 16, which is the main component for performing the cutting operation. The connecting shaft 1 7 has a slot 14 inside, which provides a positioning and engaging position for the locking block 13.

[0028] Specifically, when the saw blade 16 needs to be replaced, the operator first holds and rotates the rotating ring 9. The rotating ring 9 drives the threaded rod 10, which is fixedly connected to it, to perform threaded transmission within the rotating disk 11. The axial movement of the threaded rod 10 pushes the connecting rod 12 to produce a swinging motion. The swinging motion of the connecting rod 12 causes the locking block 13 to slide linearly within the guide groove on the inner wall of the connecting shaft 1 7. When the locking block 13 is completely disengaged from the slot 14 of the connecting shaft 2 8, the entire assembly of the connecting shaft 2 8 and the saw blade 16 can be smoothly pulled out axially from the connecting shaft 1 7, completing the disassembly operation. When installing a new saw blade, simply insert the connecting shaft 2 8 into the connecting shaft 1 7 and rotate the rotating ring 9 in the opposite direction to re-engage the locking block 13 into the slot 14 to achieve reliable fixation, ensuring the stability and safety of the saw blade 16 during operation.

[0029] Reference Figures 1-5A water tank 17 is fixedly connected to the inner wall of the workbench 1 to store coolant. A guide plate 18 is fixedly connected to the outer wall of the water tank 17 to guide the coolant return direction. A connecting pipe 20 is fixedly connected to the outer wall of the water tank 17 to deliver coolant to the water pump 21. The water pump 21 is installed outside the fixed plate 3 to provide cooling power for circulation. The input end of the water pump 21 is fixedly connected to one end of the connecting pipe 20. The output end of the water pump 21 is fixedly connected to the connecting pipe 22 to deliver coolant to the nozzle 23. One end of the connecting pipe 22 is fixedly connected to the nozzle 23 to spray coolant onto the saw blade 16. A filter plate 19 is slidably connected to the inner wall of the water tank 17 to filter metal debris in the coolant. A fixed plate 3 25 is fixedly connected to the outer wall of the workbench 1 to cooperate with the fixed plate 2 24 to fix the filter plate 19. The outer wall of the filter plate 19 is fixedly connected to the fixed plate 24. A replacement component is installed inside the fixed plate 24, which includes a sliding rod 28 to control the filter plate 19. The sliding rod 28 is slidably connected to the inner wall of the fixed plate 24. A spring 27 is sleeved on the outer wall of the sliding rod 28 to provide the sliding rod 28 with a return force. A fixed plate 26 is fixedly connected to the outer wall of the sliding rod 28. A fixed plate 29 is fixedly connected to the outer wall of the worktable 1. A fixed block 15 is fixedly connected to one end of the sliding rod 28 for manual operation of filter plate 19 replacement. The outer wall of the fixed plate 24 is slidably connected to the inner wall of the fixed plate 3 25. The outer wall of the sliding rod 28 is slidably connected to the inner wall of the fixed plate 3 25. One end of the spring 27 is fixedly connected to the outer wall of the fixed plate 26. The other end of the spring 27 is fixedly connected to the outer wall of the fixed plate 4 29. The outer wall of the sliding rod 28 is slidably connected to the inner wall of the fixed plate 4 29. The fixed block 15 is set above the fixed plate 4 29. The saw blade 16 is set above the grid 2. The outer wall of the connecting shaft 28 is slidably connected to the inner wall of the connecting shaft 1 7. The motor 6 is set above the worktable 1. The nozzle 23 is set above the worktable 1.

[0030] Specifically, water pump 21 draws coolant from water tank 17 through connecting pipe 20, and delivers it to nozzle 23 through connecting pipe 22, forming a stable coolant flow to continuously cool and lubricate the high-speed rotating saw blade 16. After use, the coolant, carrying cutting debris, flows back to water tank 17 after being filtered by grille 2, and then undergoes secondary fine filtration by filter plate 19. When filter plate 19 needs maintenance or replacement, the operator pulls the fixing block 15 outward. The fixing block 15 drives the sliding rod 28 to slide within the fixing plate 29, overcoming the elastic force of spring 27, so that fixing plate 24 is released from the constraint of fixing plate 25. At this time, filter plate 19 can be removed for cleaning or replacement. After replacement, the fixing block 15 is released, and the restoring force of spring 27 pushes the sliding rod 28 to reset, so that fixing plate 24 is re-locked into the positioning structure of fixing plate 25, ensuring that filter plate 19 is installed firmly and ensuring the normal operation of the cooling system.

[0031] Working principle: When this quick-change saw blade saw is needed, the saw blade 16 needs to be disassembled first. Rotate the rotating ring 9 to drive the threaded rod 10 to move in the threaded movement of the rotating disk 11, which in turn pushes the connecting rod 12 to swing. The connecting rod 12 drives the locking block 13 to slide along the inner wall of the connecting shaft 1 7, so that it is disengaged from the locking groove 14 of the connecting shaft 2 8. At this time, the connecting shaft 2 8 and the saw blade 16 can be pulled out from the connecting shaft 1 7 as a whole, realizing quick disassembly. When operating in reverse, the locking block 13 is re-locked into the locking groove 14, which can complete the fixation of the saw blade 16 and ensure the stability of operation.

[0032] In addition, the coolant in the water tank 17 is drawn by the water pump 21 through the connecting pipe 20 and delivered to the nozzle 23 through the connecting pipe 22 to cool and lubricate the saw blade 16. After use, the coolant flows back to the water tank 17 through the grille 2 and is filtered by the filter plate 19. When the filter plate 19 needs to be replaced, the fixing block 15 is pulled outward, which drives the sliding rod 28 to slide against the elastic force of the spring 27, so that the fixing plate 24 is released from the restriction of the fixing plate 3 25, and the filter plate 19 can be removed. After replacement, the fixing block 15 is released, and the spring 27 pushes the sliding rod 28 to reset, so that the fixing plate 24 is re-fixed in the fixing plate 3 25, ensuring the stable installation of the filter plate 19.

[0033] 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.
