[0029] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0030] See Figures 1 to 7 This utility model discloses a sawing device with a safety rebound structure, including: a base 10; a drive unit 20, which is disposed on the base 10; a saw blade 30, the output end of which is connected to the saw blade 30 to drive the saw blade 30 to rotate; and a safety rebound structure 40, which is rotatably connected to the base 10. The safety rebound structure 40 includes a rebound member 401, which is disposed beside the cutting edge of the saw blade 30. The rebound member 401 includes at least one flexible body 4011, which is disposed on the surface of the rebound member 401 or in the middle of the rebound member 401.

[0031] This utility model uses a safety rebound structure 40 to intercept sawing waste, thereby reducing the impact damage caused by the rebounding and projectile of the saw blade 30 when sawing wood. The safety rebound structure 40 is rotatably connected to the base 10, and the operating angle of the safety rebound structure 40 can be adjusted according to actual needs. Furthermore, the rebound component 401 in the safety rebound structure 40 includes at least one flexible body 4011, which can increase the buffering capacity of the safety rebound structure 40.

[0032] It should be noted that the saw blade 30 is a circular saw blade with serrated edges. The output end of the drive unit 20 is connected to the central axis of the saw blade 30 to drive the saw blade 30 to rotate.

[0033] In this embodiment of the utility model, the rebound member 401 further includes a first rigid body 4012 and a second rigid body 4013, and a flexible body 4011 is disposed in the middle position of the rebound member 401, and the flexible body 4011 is sandwiched between the first rigid body 4012 and the second rigid body 4013.

[0034] See Figure 4 as well as Figure 5 For example, the flexible body 4011 can be a silicone sheet or a rubber sheet, and the first rigid body 4012 can be a steel plate, an iron plate or a wooden board.

[0035] The flexible body 4011 can be glued between the first rigid body 4012 and the second rigid body 4013, or the flexible body 4011 can be detachably connected to the first rigid body 4012 and the second rigid body 4013 by screws.

[0036] In this embodiment of the utility model, the safety rebound structure 40 further includes a cantilever 402 and an adjusting seat 403; the adjusting seat 403 is provided with a first adjusting groove 404, which extends along a first direction or along a second direction; the base 10 is provided with a first threaded hole 101; the first adjusting screw 50 is threadedly connected to the first threaded hole 101 through the first adjusting groove 404, so that the adjusting seat 403 is movably connected to the base 10; the adjusting seat 403 is provided with a rotating shaft 405; the first end of the cantilever 402 is provided with a rotating connection hole 406; the cantilever 402 is sleeved on the rotating shaft 405 through the rotating connection hole 406, so that the first end of the cantilever 402 is rotatably connected to the adjusting seat 403; and the rebound member 401 is provided at the second end of the cantilever 402.

[0037] It should be noted that the first direction is the X-axis direction of the coordinate system, and the second direction is the Z-axis direction of the coordinate system.

[0038] The rebound component 401 can be detachably connected to the second end of the cantilever 402 by screws, or the rebound component 401 can be fixedly connected to the second end of the cantilever 402 by welding or other processes.

[0039] For example, see Figure 2 , Figure 4 as well as Figure 5 The first adjustment groove 404 extends along the second direction, that is, the first adjustment groove 404 extends along the Z-axis of the coordinate system, so that when the first adjustment screw 50 is loosened, the adjustment seat 403 can be adjusted up and down along the Z-axis of the coordinate system; since the first end of the cantilever 402 is rotatably connected to the adjustment seat 403, and the rebound member 401 is set at the second end of the cantilever 402, the safety rebound structure 40 as a whole can be adjusted up and down along the Z-axis of the coordinate system.

[0040] Furthermore, since the safety rebound structure 40 is used to intercept sawing waste, meaning that the safety rebound structure 40 will be impacted by the waste during use, in order to increase the connection stability between the safety rebound structure 40 and the base 10, an auxiliary connecting screw 60 can be added in some application scenarios. The adjusting seat 403 is movably connected to the base 10 through the auxiliary connecting screw 60. Of course, the safety rebound structure 40 can also be used when the auxiliary connecting screw 60 is not provided.

[0041] Since the first adjusting screw 50 extends along the X-axis of the coordinate system and the auxiliary connecting screw 60 extends along the Z-axis of the coordinate system, and the first adjusting screw 50 and the auxiliary connecting screw 60 are perpendicular to each other, the connection stability between the adjusting seat 403 and the base 10 is improved, thereby improving the connection stability between the safety rebound structure 40 and the base 10.

[0042] In the case where the auxiliary connecting screw 60 is not provided, when adjusting the safety rebound structure 40, loosen the first adjusting screw 50, adjust the position adjusting seat 403 up and down along the Z-axis of the coordinate system to the predetermined position, and then tighten the first adjusting screw 50 to complete the position adjustment of the adjusting seat 403.

[0043] When the auxiliary connecting screw 60 is provided, during the adjustment of the safety rebound structure 40, the auxiliary connecting screw 60 and the first adjusting screw 50 are loosened, the position adjusting seat 403 is adjusted up and down along the Z-axis of the coordinate system to the predetermined position, the first adjusting screw 50 is locked, and the auxiliary connecting screw 60 is installed, thus completing the position adjustment of the adjusting seat 403.

[0044] Based on the above structure, the cantilever 402 is rotatably connected to the adjusting seat 403 via the rotating shaft 405. The cantilever 402 and the rebound member 401 can rotate around the central axis of the rotating shaft 405 to realize the angle adjustment of the rebound member 401. Combined with the vertical position adjustment of the adjusting seat 403, a multi-dimensional adjustment structure is formed, and its angle and position can be adjusted to adapt to different wood materials.

[0045] In this embodiment of the present invention, the sawing device with a safety rebound structure further includes a separating blade 70, which is positioned close to the cutting edge of the sawing blade 30. The separating blade 70 has an arc-shaped portion 701 facing the cutting edge of the sawing blade 30. A second adjusting groove 702 is provided on the separating blade 70, which extends along a first direction or along a second direction. A second threaded hole 102 is provided on the base 10. A second adjusting screw 80 is threadedly connected to the second threaded hole 102 through the second adjusting groove 702, so that the separating blade 70 is movably connected to the base 10.

[0046] See Figures 1 to 3 as well as Figure 6The first adjustment groove 404 extends along the second direction, that is, the first adjustment groove 404 extends along the second direction in the Z-axis direction of the coordinate system, so that when the second adjustment screw 80 is loosened, the material divider 70 can adjust its position up and down along the Z-axis direction of the coordinate system.

[0047] When adjusting the material divider 70, loosen the second adjusting screw 80, adjust the position of the material divider 70 up and down along the Z-axis of the coordinate system to the predetermined position, and then tighten the second adjusting screw 80 to complete the position adjustment of the material divider 70.

[0048] In this embodiment of the utility model, the base 10 includes a first mounting base 103; the drive unit 20 includes a first drive member 201, the output end of the first drive member 201 is connected to the saw blade 30 to drive the saw blade 30 to rotate, and the first drive member 201 is disposed on the first mounting base 103.

[0049] For example, see Figures 1 to 3 The first driving component 201 is a motor, and the output end of the motor is connected to the saw blade 30 to drive the saw blade 30 to rotate.

[0051] For example, see Figures 1 to 3 The first direction is the X-axis direction of the coordinate system, and the second driving component 202 is a motor, hydraulic cylinder, or pneumatic cylinder.

[0052] When the second driving member 202 is a motor, the second driving member 202 is connected to the first mounting base 103 through a lead screw slide mechanism. The second driving member 202 drives the first mounting base 103 to slide along the first slide rail 105 by rotating, so that the saw blade 30 can move along the X-axis of the coordinate system.

[0053] When the second driving member 202 is a hydraulic cylinder or a pneumatic cylinder, the output end of the second driving member 202 is directly connected to the first mounting base 103 for transmission. The output end of the second driving member 202 drives the first mounting base 103 to slide along the first slide rail 105 through extension and retraction, so that the saw blade 30 can move along the X-axis of the coordinate system.

[0054] In this embodiment of the utility model, the base 10 includes a third mounting base 106; the drive unit 20 includes a third drive member, the output end of the third drive member is connected to the second mounting base 104 in a transmission connection, the third mounting base 106 is provided with a second slide rail 107, the second slide rail 107 extends along a second direction, the second mounting base 104 is slidably connected to the third mounting base 106 through the second slide rail 107, and the third drive member drives the second mounting base 104 to slide along the second slide rail 107.

[0055] For example, see Figures 1 to 3 The second direction is the Y-axis direction of the coordinate system, and the second driving component 202 is a motor, hydraulic cylinder, or pneumatic cylinder.

[0056] When the third driving component is a motor, the third driving component and the second mounting base 104 are connected by a lead screw slide mechanism. The third driving component drives the second mounting base 104 to slide along the second slide rail 107 by rotating, so that the saw blade 30 can move along the Y-axis of the coordinate system.

[0057] When the third driving component is a hydraulic cylinder or a pneumatic cylinder, the output end of the third driving component is directly connected to the second mounting base 104 for transmission. The output end of the third driving component drives the second mounting base 104 to slide along the second slide rail 107 through extension and retraction, so that the saw blade 30 can move along the Y-axis of the coordinate system.

[0059] See Figures 1 to 2 The third adjustment groove 901 extends along the second direction, that is, the third adjustment groove 901 extends along the Z-axis of the coordinate system, so that the dust baffle 90 can be adjusted up and down along the Z-axis of the coordinate system.

[0060] When adjusting the dust baffle 90, loosen the third adjusting screw 100, adjust the position of the dust baffle 90 up and down along the Z-axis of the coordinate system to the predetermined position, and then tighten the third adjusting screw 100 to complete the position adjustment of the dust baffle 90.

[0062] When using this invention for wood sawing, the user stands at the feeding end and pushes the wood. Since the saw blade 30 is located at the discharge end, the separating blade 70 can reduce the occurrence of wood jamming during sawing. Furthermore, since the feeding end of the saw blade 30 is equipped with a safety rebound structure 40 and a dust baffle 90, the rebound and impact injury caused by edge material to the user can be reduced.

[0063] In this embodiment of the invention, the base 10 further includes a protective cover 109, which covers the top of the saw blade 30.

[0064] For example, see Figures 1 to 3 as well as Figure 7 The protective cover 109 is placed on top of the saw blade 30 to protect the top of the saw blade 30 and prevent injury to the user; the wood can move along its conveying direction A to be sawed through the side of the saw blade 30.
