[0037] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0038] The following is in conjunction with the appendix Figures 1-10 This embodiment will be described in further detail.

[0039] Please see Figures 1-4 This embodiment of a band saw feeding and guiding device includes a guiding component that cooperates with the cutting assembly of the band saw. The guiding component includes a base frame 100, a conveying groove 400 within the base frame 100, and a plurality of parallel-arranged active rollers 300 within the conveying groove 400. The active rollers 300 are rotatably connected to the conveying groove 400 via bearings. The active rollers 300 rotate to convey the material 101 to be sawed. Fixed plates 200 are slidably connected within the conveying groove 400 and located on both sides. A liftable fixed frame 120 is connected, and the fixed frame 120 is lifted to accommodate materials 101 of different heights. The two sides of the bottom frame 100 are provided with driving cavities 401. The driving cavity 401 is provided with a first driving component for driving the active rotating roller 300 to rotate. The driving cavity 401 is also provided with a second driving component for driving the fixed plate 200 to move relative to each other. The bottom frame 100 is provided with an extension section 420 extending to the bottom of the cutting component of the band saw. The extension section 420 is provided with a cleaning component for cleaning the cutting component.

[0040] In this embodiment, the cutting assembly includes a bracket 110 and a saw base 111 that can be lifted and lowered on the bracket 110. A second hydraulic cylinder 113 is fixedly connected inside the bracket 110, and the output end of the second hydraulic cylinder 113 is fixedly connected to the saw base 111. A turntable 1000 is rotatably connected inside the saw base 111 via a bearing. A saw blade 1011 is sleeved between the turntables 1000. The rotation of the turntables 1000 drives the saw blade 1011 to rotate, thereby cutting the material 101. A drive mechanism is fixedly connected to the saw base 111. The first motor 112 of the rotating turntable 1000 can start when the material 101 needs to be cut. It can drive the turntable 1000 and the saw blade 1011 to rotate, and then start the second hydraulic cylinder 113 to drive the saw base 111 to move closer to the material 101 located at the bottom of the support 110, so that the rotating saw blade 1011 can cut the material 101. After the cutting is completed, the second hydraulic cylinder 113 can be started to drive the saw base 111 to move upward, so that the saw blade 1011 moves away from the material 101.

[0041] In order to fix the material 101 during cutting, an extension section 420 is fixedly connected to one side of the bottom frame 100. When cutting the material 101, the lower end of the material 101 can overlap the extension section 420, and the extension section 420 is provided with a notch for the saw blade 1011 to extend into. Thus, when the saw blade 1011 cuts, it can prevent damage to the extension section 420.

[0042] Specifically, when conveying material 101, the lower end of material 101 is attached to the active roller 300. The outer wall of the active roller 300 is a friction part with a relatively rough surface. Thus, when multiple active rollers 300 rotate in sequence, they can drive material 101 to move towards the saw blade 1011.

[0043] The relative movement of the fixed plate 200 within the conveying trough 400 allows the distance between the two fixed plates 200 to be adjusted according to specific needs when conveying materials 101 of different diameters and quantities. This limits the material 101 on both sides, making it less likely for the material 101 to tilt during conveying and facilitating subsequent cutting.

[0044] The movable arrangement of the fixed frame 120 on the fixed plate 200 allows for the adjustment of the height of the fixed frame 120 on the fixed plate 200 when conveying materials 101 of different diameters and quantities. This limits the upper part of the material 101 and, in conjunction with the relative movement of the fixed plate 200, ensures that the material 101 in the conveying trough 400 is guided and limited in multiple dimensions. This allows the device to accommodate materials 101 of different quantities and diameters, thereby improving the conveying effect of the feeding guide device.

[0045] The cleaning component is designed so that when the saw blade 1011 in the cutting assembly is sawing the material 101, and powder from the material 101 accumulates on the saw blade 1011, the cleaning component can clean the powder on the saw blade 1011 to keep the saw blade 1011 clean.

[0046] Combination Figures 1-6In this embodiment, the two ends of the active roller 300 are fixedly connected to a first connecting shaft 310 and a second connecting shaft 600. One end of the first connecting shaft 310 and the second connecting shaft 600 extends into the corresponding drive cavity 401. The first connecting shaft 310 and the second connecting shaft 600 are rotatably connected to the bottom frame 100 through bearings. A first sprocket 311 is fixedly connected to the first connecting shaft 310 located in the drive cavity 401. A second sprocket 601 is fixedly connected to the second connecting shaft 601 located in the drive cavity 401. A first chain 312 for transmission is rotatably connected between adjacent first sprockets 311. A second chain for transmission is rotatably connected between adjacent second sprockets 601.

[0047] In this embodiment, a motor mounting bracket 210 is fixedly connected inside the drive cavity 401, and a second motor 211 is fixedly connected to the motor mounting bracket 210. The output shaft of the second motor 211 is fixedly connected to one of the first connecting shafts 310. When the second motor 211 starts, it can drive the first connecting shaft 310 to rotate. Under the transmission of the first sprocket 311, the first chain 312, the second sprocket 601, and the second chain, multiple active rollers 300 can rotate sequentially to convey the material 101.

[0048] Combination Figures 1-4 In this embodiment, a first hydraulic cylinder 202 is fixedly connected inside the drive cavity 401. The output shaft of the first hydraulic cylinder 202 extends into the conveying groove 400 and is fixedly connected to the fixing plate 200.

[0049] In this embodiment, the movement of the fixed plate 200 can be controlled by the first hydraulic cylinder 202, so as to control the distance between the two fixed plates 200, thereby adapting to different quantities of materials 101.

[0050] In order to guide the movement of the fixed plate 200, the side wall of the bottom frame 100 is provided with guide holes 410, and the fixed plate 200 is fixedly connected with guide rods 203 that slide within the corresponding guide holes 410.

[0051] Combination Figures 1-10 In this embodiment, a sliding groove 700 is provided on the fixing plate 200 along its height direction, and a threaded post 720 with one end extending out of the sliding groove 700 is fixedly connected to the fixing bracket 120. A nut 721 is threadedly connected to the extended end of the threaded post 720.

[0052] In this embodiment, the two ends of the fixed plate 200 extend out of the conveying groove 400, and the sliding groove 700 is provided at the extended end of the fixed plate 200. When it is necessary to adjust the distance between the fixed frame 120 and the active roller 300, the nut 721 can be turned to disengage it from the side wall of the fixed plate 200. At this time, the threaded column 720 can slide in the sliding groove 700 to adjust the distance between the fixed frame 120 and the active roller 300. When it is necessary to fix the fixed frame 120, the nut 721 can be tightened to make it fit tightly against the side wall of the fixed plate 200.

[0053] Specifically, the mounting bracket 120 is provided with multiple slots at intervals, and the mounting bracket 120 on one side can be inserted into the slot on the mounting bracket 120 on the other side, so that when the mounting brackets 120 are close to each other, they will not interfere with each other.

[0054] In order to prevent the material 101 from being compressed when the fixed frame 120 approaches it, making it difficult to move, a mounting bracket 900 is fixedly connected to the lower end of the fixed frame 120. A passive roller 910 is rotatably connected to the mounting bracket 900 through a bearing, so that the upper end of the material 101 slides in contact with the passive roller 910. This changes the friction between the material 101 and the fixed frame 120 from sliding friction to rolling friction, reducing the friction between the two and making the material 101 easier to move.

[0055] Combination Figures 4-8 In this embodiment, the cleaning component includes a mounting plate 500 fixedly connected to the extension section 420. A bolt 520 is threadedly connected to the mounting plate 500. One end of the bolt 520 is rotatably connected to a movable plate 510. Specifically, the movable plate 510 is provided with a bearing seat 830. One end of the bolt 520 extends into the bearing seat 830. The movable plate 510 is provided with a detachable cleaning plate 511. A plurality of brushes 512 are fixedly connected to the cleaning plate 511. The rotating bolt 520 is used to move the movable plate 510 closer to or away from the notch.

[0056] In this embodiment, when the saw blade 1011 needs to be cleaned, since the bolt 520 is threadedly connected to the mounting plate 500 and one end of the bolt 520 is rotatably connected to the moving plate 510, when the bolt 520 is rotated, since one side wall of the moving plate 510 abuts against the side wall of the extension section 420, the moving plate 510 will not rotate, but will move closer to or away from the notch, driving the cleaning plate 511 and the brush 512 closer to the saw blade 1011, so that the brush 512 contacts the side wall of the saw blade 1011, thereby causing the powder to fall off the saw blade 1011;

[0057] The movable design of the movable plate 510 enables it to clean saw blades 1011 of different thicknesses.

[0058] The brush 512 is made of nylon so that it can brush the saw blade 1011. The detachable design of the cleaning plate 511 allows the brush 512 on the cleaning plate 511 to be removed from the moving plate 510 for replacement or cleaning when it becomes worn or accumulates a lot of powder after a period of use.

[0059] Combination Figures 4-8 In this embodiment, the movable plate 510 is provided with a T-shaped groove 800, and the cleaning plate 511 is fixedly connected with a T-shaped block 810 that slides in the T-shaped groove 800. The side of the movable plate 510 is provided with locking bolts for fixing the T-shaped block 810.

[0060] In this embodiment, when the locking bolt is turned, it can fix or unfix the T-block 810 so that the T-block 810 can slide into or out of the T-groove 800 for the cleaning plate 511 to be disassembled and assembled.

[0061] The movable plate 510 has a round hole on the side away from the T-slot 800 that communicates with the T-slot 800. The T-block 810 has a threaded groove. When the T-block 810 is fully inserted into the T-slot 800, the round hole and the threaded groove correspond to each other. The locking bolt passes through the round hole and is threadedly connected to the threaded groove, so that the T-block 810 can be stably fixed in the threaded groove.

[0062] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
