Description

Technical Field

[0001] This utility model relates to the field of cutting technology, and in particular to a sawing machine. Background Technology

[0002] A sawing machine is needed to process the molds for prefabricated buildings. The sawing machine cuts materials such as steel plates or pipes into the required shapes and sizes. A sawing machine generally includes a frame, two saw wheels, a ring saw blade, and two reversing assemblies. The two saw wheels are mounted on the frame with their axes roughly horizontal. The ring saw blade is mounted between the two saw wheels and driven by them. The two reversing assemblies are located on the frame at both ends of the lower section of the ring saw blade. Each reversing assembly includes two clamping rollers with their axes vertical. The two clamping rollers cooperate to clamp the end face of the ring saw blade in the thickness direction, thus twisting the lower section of the ring saw blade so that the saw teeth face downwards, facilitating the cutting of the material below the ring saw blade.

[0003] However, the cutting angle of the ring saw blade in existing sawing machines cannot be adjusted. In addition, the material cut by the ring saw blade will adhere to the cut material, which can easily cause the ring saw blade to get stuck when passing through the clamping roller. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a sawing machine that not only allows adjustment of the cutting angle of the ring saw blade, but also facilitates cleaning of the lower section of the ring saw blade when it is twisted at different angles, reducing the possibility of the ring saw blade getting stuck when passing through the clamping roller.

[0005] A sawing machine according to an embodiment of the present invention includes a frame, a ring saw blade, two reversing assemblies, and a cleaning brush. The frame has a first saw wheel and a second saw wheel arranged side by side. The ring saw blade is installed between the first saw wheel and the second saw wheel. The ring saw blade includes an upper section and a lower section. The lower section moves from the first saw wheel to the second saw wheel. The two reversing assemblies are located at both ends of the lower section. Each reversing assembly includes a mounting frame, a first rotating part, and two first clamping rollers. The mounting frame is mounted on the frame. The first rotating part is rotatably and adjustablely mounted on the mounting frame. The rotation axis of the first rotating part extends along the length direction of the lower section. The two first clamping rollers are rotatably mounted on the first rotating part and are located on both sides of the thickness direction of the lower section. The cleaning brush is disposed on the first rotating part adjacent to the second saw wheel and is located on the side of the first clamping roller adjacent to the second saw wheel that is away from the second saw wheel. The cleaning brush is in contact with the lower section.

[0006] The sawing machine according to the embodiments of this utility model has at least the following beneficial effects:

[0007] In this application, the first saw wheel and the second saw wheel drive the ring saw blade to move by rotating. The lower section of the ring saw blade can cut the material. The two first clamping rollers corresponding to the two direction-changing components cooperate to clamp the lower section. The first clamping rollers are installed on the first rotating part that can be rotated and adjusted. By rotating and adjusting the first rotating part, the axial direction of the two corresponding first clamping rollers can be adjusted, and the lower section can be twisted according to actual needs to adjust the orientation of the saw teeth of the lower section, thereby adjusting the cutting angle of the lower section. Meanwhile, the cleaning brush is located on the side of the first clamping roller adjacent to the second saw wheel, away from the second saw wheel. The cleaning brush adheres to the lower section. Before the lower section enters the two first clamping rollers adjacent to the second saw wheel, it will be cleaned by the cleaning brush to prevent the ring saw blade from adhering too much fine debris, which could cause it to get stuck when passing through the first clamping rollers. In addition, the cleaning brush is located on the first rotating part adjacent to the second saw wheel. Thus, when the first rotating part rotates and drives the lower section of the ring saw blade to twist to different angles, the cleaning brush can rotate with the first rotating part, making it easy for the cleaning brush to adhere to the lower section throughout the entire process, resulting in a better cleaning effect.

[0036] The following is for reference. Figures 1 to 3 A sawing machine according to an embodiment of the present utility model is described.

[0037] The sawing machine according to an embodiment of the present invention includes a frame 100, a ring saw blade 200, two direction-changing components 300, and a cleaning brush 400.

[0038] The frame 100 has a first saw wheel 101 and a second saw wheel 102 arranged side by side. For example, the first saw wheel 101 and the second saw wheel 102 can be arranged in a left-right direction, and the axis of the first saw wheel 101 and the second saw wheel 102 can extend horizontally or be slightly inclined relative to the horizontal direction. A ring saw blade 200 is installed between the first saw wheel 101 and the second saw wheel 102. One of the first saw wheel 101 and the second saw wheel 102 can be driven by a drive motor. The drive motor drives one of the first saw wheel 101 and the second saw wheel 102 to rotate, thereby moving the ring saw blade 200. The ring saw blade 200 includes an upper section 201 and a lower section 202. When the ring saw blade 200 moves, the lower section 202 moves from the first saw wheel 101 to the second saw wheel 102.

[0039] Two reversing assemblies 300 are located at both ends of the lower section 202. Each reversing assembly 300 includes a mounting frame 301, a first rotating part 302, and two first clamping rollers 303. The mounting frame 301 is mounted on the frame 100. The first rotating part 302 is rotatably and adjustablely mounted on the mounting frame 301. The rotation axis of the first rotating part 302 extends along the length direction of the lower section 202. The two first clamping rollers 303 are rotatably mounted on the first rotating part 302. The two first clamping rollers 303 are located on both sides of the thickness direction of the lower section 202. A cleaning brush 400 is disposed on the first rotating part 302 adjacent to the second saw wheel 102 and is located on the side of the first clamping roller 303 adjacent to the second saw wheel 102 away from the second saw wheel 102. The cleaning brush 400 is attached to the lower section 202.

[0040] In this application, the first saw wheel 101 and the second saw wheel 102 drive the annular saw blade 200 to move by rotation. The lower section 202 of the annular saw blade 200 can cut the material. The two first clamping rollers 303 corresponding to the two direction-changing components 300 cooperate to clamp the lower section 202. The first clamping rollers 303 are installed on the rotatable and adjustable first rotating part 302. By rotating and adjusting the first rotating part 302, the axial direction of the corresponding two first clamping rollers 303 can be adjusted. In this way, the lower section 202 can be twisted according to actual needs, and the orientation of the saw teeth of the lower section 202 can be adjusted, thus adjusting the cutting angle of the lower section 202. Meanwhile, the cleaning brush 400 is located on the side of the first clamping roller 303 adjacent to the second saw wheel 102 that is away from the second saw wheel 102. The cleaning brush 400 is attached to the lower section 202. Before the lower section 202 enters the two first clamping rollers 303 adjacent to the second saw wheel 102, it will be cleaned by the cleaning brush 400 to prevent the annular saw blade 200 from adhering too much fine debris, which would cause it to get stuck when passing through the first clamping rollers 303. In addition, the cleaning brush 400 is located on the first rotating part 302 adjacent to the second saw wheel 102. Thus, when the first rotating part 302 rotates and drives the lower section 202 of the annular saw blade 200 to rotate to different angles, the cleaning brush 400 can rotate with the first rotating part 302, so that the cleaning brush 400 can be attached to the lower section 202 throughout the entire process, resulting in a better cleaning effect.

[0041] It should be noted that the ring saw blade 200 includes an upper section 201 and a lower section 202. The upper section 201 is roughly located above the lower section 202. The upper section 201 is the return section, and the lower section 202 is the cutting section.

[0042] refer to Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the mounting bracket 301 is provided with a plurality of first connecting holes 304 corresponding to the first rotating part 302. The plurality of first connecting holes 304 are arranged circumferentially along the rotation axis of the first rotating part 302. The first rotating part 302 can rotate to install a first fastener 305 between different first connecting holes 304.

[0043] For example, the first rotating part 302 is provided with a plurality of first mounting holes. The first rotating part 302 can rotate until the first mounting holes are aligned with different first connecting holes 304, thereby installing the first fastener 305. In this way, the rotation adjustment of the first rotating part 302 can be realized. Moreover, after the first rotating part 302 is rotated to adjust to a preset angle, it can be locked by the first fastener 305. The structure is simple and the adjustment is convenient.

[0044] It should be noted that the first rotating part 302 can also be rotated and adjusted in other ways. For example, the first rotating part 302 can be rotated and adjusted by the extension and retraction of the hydraulic cylinder or the rotation of the motor.

[0045] refer to Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the arrangement direction of the two first clamping rollers 303 of the same direction changing component 300 is perpendicular to the length direction of the lower section 202, the axial direction of the first clamping roller 303 is perpendicular to the length direction of the lower section 202, and the arrangement direction of the two first clamping rollers 303 of the same direction changing component 300 is perpendicular to the axial direction of the first clamping roller 303.

[0046] In this embodiment, the arrangement is such that when the first rotating part 302 rotates, the two first clamping rollers 303 cooperate to twist the lower section 202 of the annular saw blade 200 more effectively.

[0047] refer to Figure 1 and Figure 2 As shown, in some embodiments of this utility model, two first rotating parts 302 are located on the side of the two mounting frames 301 that are close to each other. The reversing assembly 300 also includes a second rotating part 306 and two second clamping rollers 307. The second rotating part 306 is rotatably and adjustablely mounted on the mounting frame 301. The two second rotating parts 306 are located on the side of the two mounting frames 301 that are opposite to each other. The rotation axis of the second rotating part 306 extends along the length direction of the lower section 202. The two second clamping rollers 307 of the same reversing assembly 300 are rotatably mounted on the second rotating part 306. The two second clamping rollers 307 are located on both sides of the thickness direction of the lower section 202.

[0048] When the lower section 202 of the ring saw blade 200 needs to be twisted at a large angle, for example, 90°, the lower section 202 of the ring saw blade 200 is easily damaged due to excessive local twisting angle.

[0049] In this embodiment, a rotatable and adjustable second rotating part 306 is also installed on one side of the two mounting brackets 301 that are opposite to each other. The rotation axis of the second rotating part 306 extends along the length direction of the lower section 202. Two rotatable second clamping rollers 307 are also installed on the second rotating part 306. The two second clamping rollers 307 are located on both sides of the thickness direction of the lower section 202. In this way, by rotating and adjusting the second rotating part 306, the corresponding two second clamping rollers 307 can cooperate to pre-twist the lower section 202 of the ring saw blade 200, that is, to twist it by a small angle in advance, so as to avoid damage caused by excessive local twisting angle of the lower section 202 of the ring saw blade 200.

[0050] and Figure 3The installation method of the first rotating part 302 shown is similar. In some embodiments of this utility model, the mounting bracket 301 is provided with a plurality of second connecting holes corresponding to the second rotating part 306. The plurality of second connecting holes are arranged circumferentially along the rotation axis of the second rotating part 306. The second rotating part 306 can rotate to install the second fastener 308 between different second connecting holes.

[0051] For example, the second rotating part 306 is provided with a plurality of second mounting holes. The second rotating part 306 can rotate to align the second mounting holes with different second connecting holes, thereby installing the second fastener 308. In this way, the rotation adjustment of the second rotating part 306 can be realized. Moreover, after the second rotating part 306 is rotated to the preset position, it can be locked by the second locking member. The structure is simple and the adjustment is convenient.

[0052] It should be noted that the second rotating part 306 can also be rotated and adjusted in other ways. For example, the second rotating part 306 can be rotated and adjusted by the extension and retraction of the hydraulic cylinder or the rotation of the motor.

[0053] refer to Figure 2 As shown, in some embodiments of this utility model, the arrangement direction of the two second clamping rollers 307 of the same direction-changing component 300 is perpendicular to the length direction of the lower section 202, the axial direction of the second clamping rollers 307 is perpendicular to the length direction of the lower section 202, and the arrangement direction of the two second clamping rollers 307 of the same direction-changing component 300 is perpendicular to the axial direction of the second clamping rollers 307.

[0054] In this embodiment, the arrangement is such that when the second rotating part 306 rotates, the two second clamping rollers 307 cooperate to twist the lower section 202 of the annular saw blade 200 more effectively.

[0055] refer to Figure 2 As shown, in some embodiments of this utility model, the cleaning brush 400 is attached to the saw teeth of the lower section 202. When the lower section 202 of the annular saw blade 200 is cutting, a large amount of fine debris tends to adhere to the saw teeth of the lower section 202. In this embodiment, the cleaning brush 400 is attached to the saw teeth of the lower section 202, thus improving the cleaning effect of fine debris.

[0056] refer to Figure 2As shown, in some embodiments of this utility model, the cleaning brush 400 is connected to a driving mechanism, which drives the cleaning brush 400 to rotate. The rotation axis of the cleaning brush 400 extends along the length direction of the lower section 202. In this embodiment, activating the driving mechanism causes the cleaning brush 400 to rotate, thereby enabling the cleaning brush 400 to clean the lower section 202 of the annular saw blade 200. Furthermore, because the rotation axis of the cleaning brush 400 extends along the length direction of the lower section 202, the cleaning effect is better, and the amount of debris sprayed onto the first clamping roller 303 is reduced.

[0057] refer to Figure 2 As shown, in some embodiments of this utility model, the sawing machine further includes a cooling mechanism 500, which includes a spray pipe and a plurality of nozzles. The spray pipe is disposed on at least one first rotating part 302, and the plurality of nozzles are disposed on the spray pipe and face the lower section 202. For example, the spray pipe may be connected to a water inlet pipe, which is connected to a water tank.

[0058] The inlet pipe delivers cooling water into the spray pipe, which is then sprayed through multiple nozzles onto the lower section 202 of the ring saw blade 200. This not only cools the ring saw blade 200, preventing overheating and damage, but also further cleans the lower section 202, improving its practicality. Furthermore, the spray pipe is located at at least one first rotating part 302. This ensures that even when the first rotating part 302 rotates, causing the lower section 202 of the ring saw blade 200 to twist to different angles, the spray pipe rotates with the first rotating part 302, allowing the nozzles to always face the lower section 202, resulting in better cooling and cleaning.

[0059] refer to Figure 2 As shown, in some embodiments of this utility model, a baffle plate 309 is provided on the first rotating part 302 adjacent to the second saw wheel 102. The baffle plate 309 is located on the outside of the lower section 202 and is also located between the cleaning brush 400 and the first clamping roller 303 adjacent to the second saw wheel 102. The spray pipe is located on the side of the baffle plate 309 near the lower section 202. In this embodiment, the baffle plate 309 is provided to prevent the cooling water sprayed from the nozzle from splashing outwards randomly. Moreover, since the baffle plate 309 is located between the cleaning brush 400 and the first clamping roller 303 adjacent to the second saw wheel 102, and the spray pipe is located on the side of the baffle plate 309 near the lower section 202, it not only facilitates the cooling water sprayed from the nozzle to further clean the lower section 202, but also reduces the impact of the cooling water on the cleaning brush 400.

[0060] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
