Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal cutting and sawing equipment, specifically a high-efficiency sawing mechanism. Background Technology

[0002] In the woodworking industry, it is frequently necessary to cut boards to remove unwanted parts or cut boards to the required dimensions. Many existing sawing mechanisms for board cutting are often semi-automated. Once assembled, these mechanisms often cannot adjust the position of the saw blade, limiting them to processing only one specific size of board, resulting in low sawing efficiency. When other sizes need to be cut, the saw blade and other components must be manually disassembled and repositioned. These existing sawing mechanisms are inconvenient to adjust, require highly skilled operators, and are inherently cumbersome to operate. Furthermore, processing only one board at a time leads to low sawing efficiency.

[0003] In addition, existing sawing facilities often lack dust collection devices, resulting in numerous on-site sawing operations that cannot collect dust and are inconvenient to clean. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a high-efficiency sawing mechanism that can solve the problems described in the background art.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a high-efficiency sawing mechanism, including a saw base, a first motor, a second motor, a lifting mechanism, a first saw blade, a second saw blade, a first rotating shaft, a second rotating shaft, a first mounting base, and a second mounting base. Both the first and second mounting bases are fixedly or detachably mounted on the saw base. One end of the first rotating shaft is rotatably mounted on the first mounting base, allowing the first rotating shaft to rotate relative to the first mounting base. One end of the second rotating shaft is rotatably mounted on the second mounting base, allowing the second rotating shaft to rotate relative to the second mounting base.

[0006] The other ends of both the first and second rotating shafts extend away from the saw base, such that both ends are located on one side of the saw base. The first rotating shaft is driven by a first motor, allowing the first motor to drive its rotation. The second rotating shaft is driven by a second motor, allowing the second motor to drive its rotation. The other end of the first rotating shaft is connected to a first saw blade, which is fitted onto the first rotating shaft. The other end of the second rotating shaft is connected to a second saw blade, which is fitted onto the second rotating shaft.

[0007] The lifting mechanism is used to drive the first mounting base and the second mounting base to move in the vertical direction, so as to adjust the position of the first mounting base and the second mounting base.

[0008] Furthermore, the first mounting base and the second mounting base are arranged in parallel and spaced apart, and the first saw blade and the second saw blade are on a straight line.

[0009] Furthermore, it also includes a dust collection frame, which is fixedly connected to the saw base and arranged parallel to the saw base, with the dust collection frame located on one side of the saw base.

[0010] Both the first and second saw blades are located at the top of the dust collection frame.

[0011] Furthermore, the dust collection frame is equipped with a dust collection trough, which is used to collect wood chips and other dust generated by the first saw blade and / or the second saw blade during the sawing operation of the board. The dust collection trough extends through the dust collection frame along the direction of gravity. The first saw blade and the second saw blade can move vertically within the dust collection trough, such that the lower ends of the first saw blade and the lower ends of the second saw blade move downwards and extend into the dust collection trough, and that the lower ends of the first saw blade and the lower ends of the second saw blade move upwards and extend out of the dust collection trough.

[0012] When the lower ends of the first and second saw blades move downwards and extend into the dust collection trough, a portion of the first saw blade and a portion of the second saw blade both extend into the dust collection trough, so that the dust generated by the first and second saw blades cutting the board falls into the dust collection trough. After visual cutting is completed, the first and second saw blades can move upwards, so that the first and second saw blades are completely removed from the dust collection trough.

[0013] Furthermore, the dust collection frame is also provided with a first notch and a second notch, with a first rotating shaft located above the first notch and a second rotating shaft located above the second notch, such that when the first rotating shaft moves downward to the lower limit position, the first rotating shaft abuts against the first notch, and when the second rotating shaft moves downward to the lower limit position, the second rotating shaft abuts against the second notch.

[0014] Furthermore, an external connection is connected to the end of the dust collection frame away from the first and second saw blades. The external connection communicates with the dust collection trough and is used to connect with external equipment so that the external equipment can suck away the dust in the dust collection trough.

[0015] Furthermore, the width of the dust collection trough gradually narrows along the direction of gravity, the width of the outer part is smaller than the width of the lower end of the dust collection trough, and the length of the outer part is the same as the length of the dust collection trough.

[0016] Furthermore, it also includes a shelf, the upper end of which abuts against the saw base. The shelf can be detached from the saw base, allowing it to move closer to and further away from it.

[0017] The high-efficiency sawing mechanism also includes a guide rail and a magnetic levitation assembly. The guide rail is fixed to the external target support surface, and the magnetic levitation assembly is mounted on the saw holder or other components. The magnetic levitation assembly is used to suspend the shelf and the first and second cutting saw assemblies on the shelf in the air. The first cutting saw assembly includes a first mounting base, a first rotating shaft, and a first saw blade. The second cutting saw assembly includes a second mounting base, a second rotating shaft, and a second saw blade, which are suspended in the air.

[0018] The saw holder is slidably mounted on the guide rail, allowing the highly efficient sawing mechanism to move along the guide rail.

[0019] Furthermore, the shelf is a flat plate, and several limiting mounting seats are provided on the shelf. Each limiting mounting seat is arranged in parallel and spaced apart. Each limiting mounting seat is located on the edge of the shelf near one side edge. The limiting mounting seats are used to provide installation connection parts.

[0020] Furthermore, it also includes a dust removal nozzle and a dust discharge groove. The dust discharge groove is fixedly or detachably installed on one side of the dust collection frame. The dust discharge groove is provided with a channel groove for discharging dust. The dust removal nozzle is detachably installed on the dust discharge groove. When the dust removal nozzle is installed on the dust discharge groove, the exhaust port of the dust removal nozzle is aligned with the dust discharge groove.

[0021] The beneficial effects of this utility model are as follows: This utility model can raise and lower the first and second saw blades through a lifting mechanism, achieving fine adjustment of the saw blade position. This allows for adjustment of the saw blade position according to the thickness of the board material, meeting the cutting needs of boards of different sizes. Furthermore, adjusting the saw blade position does not require disassembly or manual mechanical adjustment, making it operator-friendly and more convenient. Additionally, the dust collection frame and the fact that the lower end of the saw blade is inserted into the dust collection trough during cutting operations prevent dust from spreading randomly, effectively collecting dust and facilitating cleaning. Moreover, connecting to an external vacuum cleaner via an external connection allows for quick and automatic dust removal, further simplifying cleaning. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] like Figures 1-5 As shown, this embodiment provides a high-efficiency sawing mechanism, including a saw base 3, a dust collection frame 10, a first motor (not shown), a second motor 15, a lifting mechanism 14, a first saw blade 4, a second saw blade 5, a first rotating shaft 11, a second rotating shaft 8, a first mounting base (not shown), and a second mounting base (not shown). Both the first and second mounting bases are fixedly or detachably mounted on the saw base 3, and are arranged parallel to each other. One end of the first rotating shaft 11 is rotatably mounted on the first mounting base, allowing the first rotating shaft 11 to rotate relative to the first mounting base. One end of the second rotating shaft 8 is rotatably mounted on the second mounting base, allowing the second rotating shaft 8 to rotate relative to the second mounting base. The other ends of both the first rotating shaft 11 and the second rotating shaft 8 extend away from the saw base 3, such that the other ends of both the first rotating shaft 11 and the second rotating shaft 8 are located on one side of the saw base 3. The first rotating shaft 11 is driven by the first motor, so that the first motor can drive the first rotating shaft 11 to rotate. The second rotating shaft 8 is driven by the second motor 15, so that the second motor 15 can drive the second rotating shaft 8 to rotate. The other end of the first rotating shaft 11 is connected to the first saw blade 4, and the first saw blade 4 is sleeved on the first rotating shaft 11. The other end of the second rotating shaft 8 is connected to the second saw blade 5, and the second saw blade 5 is sleeved on the second rotating shaft 8.

[0030] The first motor can be driven to the first shaft 11 via a synchronous belt, with the two ends of the synchronous belt respectively fitted onto the first shaft 11 and the output end (i.e., the rotor) of the first motor. Similarly, the second motor 15 can be driven to the second shaft 8 via a synchronous belt, with the two ends of the synchronous belt respectively fitted onto the output end (i.e., the rotor) of the second shaft 8 and the second motor 15.

[0031] The dust collection frame 10 is fixedly connected to the saw base 3, and the dust collection frame 10 is arranged parallel to the saw base 3, with the dust collection frame 10 located on one side of the saw base 3.

[0032] The dust collection frame 10 is equipped with a dust collection trough 2, which is used to collect wood chips and other dust generated by the first saw blade 4 and / or the second saw blade 5 during the sawing operation of the board. The dust collection trough 2 extends through the dust collection frame 10 along the direction of gravity. The first saw blade 4 and the second saw blade 5 are both located at the upper end of the dust collection frame 10, and the first saw blade 4 and the second saw blade 5 can move vertically within the dust collection trough 2, such that the lower ends of the first saw blade 4 and the second saw blade 5 move downwards and extend into the dust collection trough 2, and that the lower ends of the first saw blade 4 and the second saw blade 5 move upwards and extend out of the dust collection trough 2. When the lower ends of the first saw blade 4 and the second saw blade 5 move downwards and extend into the dust collection trough 2, a portion of the first saw blade 4 and a portion of the second saw blade 5 extend into the dust collection trough 2, so that the dust generated by the first saw blade 4 and the second saw blade 5 during the sawing operation of the board falls into the dust collection trough 2. After visual inspection and sawing are completed, the first saw blade 4 and the second saw blade 5 can be moved upwards so that both the first saw blade 4 and the second saw blade 5 are completely removed from the dust collection tank 2.

[0033] Because the first mounting base and the second mounting base are arranged parallel and spaced apart, the first saw blade 4 and the second saw blade 5 are on a straight line.

[0034] For example, the dust collection frame 10 is further provided with a first recess 12 and a second recess 9. The first rotating shaft 11 is located above the first recess 12, and the second rotating shaft 8 is located above the second recess 9. This ensures that when the first rotating shaft 11 moves downward to its lower limit position, it abuts against the first recess 12, preventing the entire first saw blade 4 from extending into the dust collection trough 2. Similarly, when the second rotating shaft 8 moves downward to its lower limit position, it abuts against the second recess 9, preventing the entire second saw blade 5 from extending into the dust collection trough 2.

[0035] The dust collection frame 10 is connected to an external part 13 at the end (i.e., the lower end) away from the first saw blade 4 and the second saw blade 5. The external part 13 communicates with the dust collection trough 2 and is used to connect with an external device so that the external device can suck away the dust in the dust collection trough 2. For example, the external device can be a vacuum cleaner or other device with suction power.

[0036] For example, the width of the dust collection trough 2 gradually narrows along the direction of gravity, that is, the dust collection trough 2 has a structure that is wider at the top and narrower at the bottom. Since the processed wood chips have a certain size, the dust can be temporarily stored in the dust collection trough 2, so that when the external equipment is removed, a large amount of dust can be prevented from falling directly out of the dust collection trough 2, thus preventing the dust from falling randomly.

[0037] For example, the width of the outer part 13 is smaller than the width of the lower end of the dust collection tank 2, and the length of the outer part 13 is the same as the length of the dust collection tank 2.

[0038] For example, the upper end of the saw holder 3 also abuts against the shelf, which can be detached from the saw holder 3, allowing it to move closer to and further away from the saw holder 3. The shelf can be a flat plate, meaning its surface is planar. A plurality of limiting mounting seats 1 are provided on the shelf, with each limiting mounting seat 1 arranged parallel to each other and located near one edge of the shelf. The limiting mounting seats 1 provide mounting connection points, allowing external equipment or components to be mounted on them, and thus on the high-efficiency sawing mechanism.

[0039] Both the first mounting base and the second mounting base are fixedly or detachably mounted on the shelf.

[0040] The lifting mechanism 14 is fixedly installed on the saw base 3 and is located between the saw base 3 and the dust collection frame 10 support. The lifting mechanism 14 is used to drive the shelf to move up and down in the vertical direction, that is, it can drive the shelf to move upward or downward. This allows the first saw blade 4 and the second saw blade 5 connected to the shelf to move up and down, so that the first saw blade 4 and the second saw blade 5 extend into or out of the dust collection trough 2.

[0041] The lifting mechanism 14, which enables the drive shelf to move vertically in a linear motion, can employ existing technologies, such as linear modules, guide rod mechanisms, rack and pinion mechanisms, cam mechanisms for moving followers, screw mechanisms, linkage mechanisms, etc. The specific composition and how linear motion is achieved are not detailed here.

[0042] For example, the high-efficiency sawing mechanism also includes a guide rail and a magnetic levitation component. The guide rail is fixed to an external target support surface, for example, fixed to a work platform in a production workshop. The magnetic levitation component is installed on the saw base 3 or other components. The magnetic levitation component is used to suspend the shelf and the first and second cutting saw components on the shelf in the air. The first cutting saw component includes a first mounting base, a first rotating shaft 11 and a first saw blade 4. The second cutting saw component includes a second mounting base, a second rotating shaft 8 and a second saw blade 5. This allows for easy adjustment of the positions of the first cutting saw component and the second collection component at any time, without the need for manual disassembly of components as in the traditional method, making operation more convenient.

[0043] The saw holder 3 is slidably mounted on the guide rail, allowing the entire high-efficiency sawing mechanism to move along the guide rail and thus move to different positions.

[0044] For example, it also includes a dust removal nozzle 6 and a dust discharge groove 7. The discharge groove is fixedly or detachably installed on one side of the dust collection frame 10, and a channel groove for discharging dust is provided in the discharge groove. The dust removal nozzle 6 is detachably installed on the dust discharge groove 7. When the dust removal nozzle 6 is installed on the dust discharge groove 7, the exhaust port of the dust removal nozzle 6 is aligned with the dust discharge groove 7, so that the gas discharged by the dust removal nozzle 6 through the exhaust port can blow towards the dust discharge groove 7 to blow away the dust in the dust discharge groove 7.

[0045] When needed, the dust removal nozzle 6 can be connected to an external air blowing device. The air blowing device provides a high-speed airflow, which is discharged from the exhaust port of the dust removal nozzle 6 to blow away the dust. For example, by aiming the dust removal nozzle 6 at the dust collection tank 2, the dust in the dust collection tank 2 can be blown away, making cleaning very convenient.

[0046] The first saw blade 4 can pre-mill the board to cut a groove without cutting the board completely. After cutting the groove, the second saw blade 5 cuts the remaining part of the board after pre-milling, thus completing the cutting of the board.

[0047] This invention allows for the lifting mechanism 14 to raise and lower the first saw blade 4 and the second saw blade 5, enabling fine-tuning of the saw blade position. This allows for adjustment of the saw blade position according to different thicknesses of boards, meeting the cutting needs of boards of various sizes. Furthermore, adjusting the saw blade position does not require disassembly or manual mechanical adjustment, making it operator-friendly and more convenient. Additionally, the dust collection frame 10 and the insertion of the lower end of the saw blade into the dust collection trough 2 during cutting operations prevent dust from scattering and effectively collect it for easy cleaning. Furthermore, the external connection 13 allows for quick and automatic dust removal, further enhancing cleaning convenience.

[0048] The embodiments disclosed in this specification are merely illustrative of one aspect of the features of this utility model. The protection scope of this utility model is not limited to this embodiment, and any other functionally equivalent embodiments fall within the protection scope of this utility model. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
