[0002] The detection of the degree of wood bending is an important part of wood quality assessment. It is directly related to the performance and application range of wood.

[0015] A method for detecting wood curvature comprises the following steps:
[0016] S1. Dry the wood rod, and then use a woodworking machine to process the wood rod to a specified length, width, thickness and shape, and then place the wood rod on the top of the fixture seat so that the middle of the wood rod is perpendicular to the pressure sensing mechanism;
[0017] S2, controlling the moving beam to move downward, so that the pressure sensing mechanism at the bottom of the moving beam squeezes the wood rod to bend downward, and the pressure sensing mechanism detects the curvature of the wood rod and the pressure on the wood rod. At the same time, the moving beam squeezes the bottom baffle and extends the limit support rod downward by pressing the push rod until the wood rod breaks;
[0018] S3. After the wood rod breaks, a thrust force is generated downward from the middle, and the middle of the wood rod squeezes the bottom baffle to move quickly toward the limit baffle, so that the bottom baffle squeezes the folding push block to bend, and the clamping block squeezes the elastic limit protrusion to move toward the clamping plate. At the same time, the bottom baffle drives the clamping plate to move downward, so that the clamping block moves to the opening in the middle of the clamping plate, and the elastic limit protrusion pushes the clamping plate to drive the first fixed frame to flip, so that the transverse clamping rod flips and slides out from the bottom of the limit bayonet, so that the sliding member pushes the rectangular bracket and the X-shaped elastic telescopic frame to flip to both sides through the first spring, so that when the wood rod breaks, the parts of the wood rod pried toward the middle at both ends are blocked by the lower block.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] The present invention solves the problem of the wood rod bouncing to the sides and the top after breaking by arranging the cooperation of the pressure component and the lateral limit component. The rectangular brackets are distributed on both sides of the wood rod, so that the wood rod will directly bounce and hit the arch bracket or the lower block after breaking, and will not fly out. The lower block is used to block the upward movement space of the wood rod, and the X-shaped elastic telescopic frame blocks the lower block at the same time, so that when the wood rod hits the lower block, the X-shaped elastic telescopic frame can absorb a certain amount of kinetic energy, play a buffering role, avoid the wood rod from rebounding twice, and avoid the wood from flying and damaging equipment and personnel.
[0021] The present invention cooperates with structures such as the bottom baffle and the buffer assembly to solve the problem of downward impact after the wood rod breaks. By setting the limit baffle, the limit baffle is stuck in the middle of the limit support rod due to uneven force, so that the folding push block is folded, and the elastic limit protrusion is pushed to move, so that the clamping plate is squeezed and flipped outward by the elastic limit protrusion, and the limit of the rectangular bracket is released. The second spring has a certain buffering effect on the bottom baffle. At the same time, the elastic limit protrusion is squeezed by the folding push block. The elastic limit protrusion will be stuck between the limit support rods, further strengthening the stability between the limit baffle and the limit support rod, so that the downward impact force of the bottom baffle can be better borne, and the downward impact force of the middle part of the wood rod can be well borne, so as to avoid secondary bounce causing the wood to fly out.
[0022] The present invention cooperates with structures such as a transverse limit assembly and a buffer assembly, so that the impact bearing on the middle part of the wood and the blocking of the wood flying outward are carried out simultaneously. The elastic limit protrusion pushes the clamping plate to flip outward, so that the transverse limit assembly releases the limitation of the rectangular bracket. At this time, the elastic limit protrusion has been clamped into between the limit support rods, strengthening the fixation between the limit baffle plate and the limit support rod. At the same time, the rectangular bracket is pushed to unfold by the transverse push rod, completing the blocking and protection of the entire wood rod, preventing the wood rod from hitting personnel or equipment.

DETAILED DESCRIPTION
[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0033] like Figures 1 to 8 As shown, the present invention provides a wood curvature detection device, comprising a frame 1, a pressure component 2 is installed inside the frame 1, a support component 3 is fixedly connected to the middle of the frame 1, a pair of lateral limit components 4 are fixedly connected to the lower end of the pressure component 2, a bottom baffle 5 is slidably connected to the middle of the support component 3, buffer components 6 are arranged at both ends of the bottom baffle 5, and a wood rod 7 is placed on the top of the support component 3;
[0034] Among them, the pressure-applying component 2 includes a movable beam 21, a pressure sensing mechanism 22 is installed in the middle of the lower end of the movable beam 21, a pair of downward-pressing push rods 23 are fixedly connected to the lower end of the movable beam 21, a sliding member 24 is slidably connected inside the downward-pressing push rod 23, a first spring 25 is fixedly connected to the top of the sliding member 24, and a pair of sliding members 24 are rotatably connected to transverse push rods 26 on both sides.
[0035] The above scheme is adopted: by placing the wood rod 7 on the top of the clamp seat 32, and making the middle part of the wood rod 7 perpendicular to the pressure sensing mechanism 22, the moving crossbeam 21 drives the pressure sensing mechanism 22 to move downward to squeeze the wood rod 7, so that the wood rod 7 is deformed, and at the same time, the moving crossbeam 21 synchronously pushes the downward pressing push rod 23 to move, and the downward pressing push rod 23 pushes the bottom baffle 5 to move downward, so that the bottom baffle 5 does not directly contact the wood rod 7. When the wood rod 7 is squeezed to the limit and breaks, the middle part of the wood rod 7 will protrude downward and push the bottom baffle 5 to move downward quickly. The bottom baffle 5 blocks the downward impact force generated by the wood rod 7. At the same time, when the bottom baffle 5 moves, the limit of the rectangular bracket 41 will be released, so that the rectangular bracket 41 is squeezed and pushed to expand to both sides, and the upward-tilted two ends of the wood rod 7 are blocked by the lower stop block 43, and at the same time, the wood rod 7 is blocked from bouncing to the side, so as to avoid the middle part of the wood rod 7 hitting the base after breaking or the two ends bouncing and hitting to damage the equipment.
[0036] like Figure 2 , Figure 3 and Figure 4 As shown, the movable crossbeam 21 is slidably connected to the inside of the frame 1, the bottom of the pressure sensing mechanism 22 is in contact with the wood rod 7, the downward push rod 23 is distributed in a mirror image on both sides of the pressure sensing mechanism 22, and the top of the first spring 25 is fixedly connected to the movable crossbeam 21.
[0037] By adopting the above solution: by setting the sliding member 24, the first spring 25 and the transverse push rod 26, when the rectangular bracket 41 is released from the limit, the first spring 25 in the compressed state directly pushes the sliding member 24 to move downward, so that the sliding member 24 pushes the transverse push rod 26 to expand to both sides, thereby pushing the rectangular bracket 41 to rotate to both sides.
[0038] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the support assembly 3 includes a base 31, a clamp seat 32 is fixedly connected to the middle of the base 31, two pairs of limit support rods 33 are fixedly connected to the top of the base 31, the base 31 is located at the lower side of the movable beam 21, the clamp seat 32 is located between the two pairs of limit support rods 33, the top of the clamp seat 32 is in contact with the bottom of the wood rod 7, the limit support rod 33 is slidably connected to the bottom baffle 5, and the upper ends of the limit support rods 33 are respectively slidably connected to the downward push rod 23.
[0039] The above scheme is adopted: by setting the support assembly 3, the base 31 supports the clamp seat 32 and the limiting support rod 33, the clamp seat 32 is set for placing the wood rod 7, the clamp seat 32 cooperates with the pressure sensing mechanism 22 to apply pressure to the wood rod 7 to perform a bending test, and by setting the limiting support rod 33, the bottom baffle 5 in the middle of the limiting support rod 33 bears the downward impact force generated after the wood rod 7 breaks.
[0040] like Figure 3 , Figure 4 and Figure 8 As shown, the lateral limiting assembly 4 includes a pair of rectangular brackets 41 and a pair of X-shaped elastic telescopic frames 42, the lower end of the X-shaped elastic telescopic frame 42 is movably connected with a lower stopper 43, the lower end of the rectangular bracket 41 is provided with a limiting slide groove 44, and the bottom of the rectangular bracket 41 is provided with a limiting bayonet 45, the tops of the rectangular brackets 41 and the X-shaped elastic telescopic frame 42 are fixedly connected to the movable beam 21, the pair of rectangular brackets 41 are located in the middle of the pair of X-shaped elastic telescopic frames 42, the rectangular brackets 41 are mirror-distributed on both sides of the pressure sensing mechanism 22 and the downward push rod 23, the sides of the rectangular brackets 41 that are close to each other are rotatably connected to the lateral push rod 26, the lower side of the lower stopper 43 is in contact with the top of the wood rod 7, and the lower stopper 43 is slidably connected inside the limiting slide groove 44.
[0041] The above scheme is adopted: by setting a lateral limit assembly 4, a rectangular bracket 41 and an X-shaped elastic telescopic frame 42 cooperate, a support is formed between the rectangular bracket 41 and the X-shaped elastic telescopic frame 42, and the rectangular bracket 41 is distributed on both sides of the wood rod 7. The X-shaped elastic telescopic frame 42 pushes the lower block 43 to block the upper side of the wood rod 7, so that the wood rod 7 will directly bounce and hit the rectangular bracket 41 or the lower block 43 after breaking, and will not fly out or hit the precision parts of the equipment. By setting the rectangular bracket 41 to limit the wood The lateral movement position of the rod 7 is achieved by setting a lower stopper 43 to block the upward movement space of the wood rod 7. At the same time, the X-shaped elastic telescopic frame 42 blocks the lower stopper 43, so that when the wood rod 7 hits the lower stopper 43, the X-shaped elastic telescopic frame 42 can absorb a certain amount of kinetic energy to play a buffering role and avoid a secondary rebound of the wood rod 7. The setting of the limit bayonet 45 can ensure that the wood rod 7 releases the lock on the rectangular bracket 41 when it breaks and hits the bottom baffle 5, so that the rectangular bracket 41 and the X-shaped elastic telescopic frame 42 can be turned over and unfolded in time.
[0042] like Figures 5 to 8 As shown, the buffer assembly 6 includes a pair of first fixed frames 61 and a pair of limiting baffles 63. The first fixed frame 61 has transverse locking rods 62 fixedly connected on both sides. The top of the limiting baffle 63 is rotatably connected to a folding push block 64. The end of the limiting baffle 63 away from each other is fixedly connected to a locking block 65. The top of the limiting baffle 63 is movably connected to a movable support rod 66. The two ends of the movable support rod 66 are sleeved with second springs 67. The middle part of the movable support rod 66 is fixedly connected to an elastic limiting protrusion 68. The inside of the first fixed frame 61 is movably connected to a locking plate 69.
[0043] The above scheme is adopted: by setting up the buffer component 6, the bottom baffle plate 5 can be loaded and supported when the bottom baffle plate 5 is hit by the wooden rod 7, and a rubber friction layer is set at the connection between the limit baffle plate 63 and the limit support rod 33, so that the limit baffle plate 63 will not be pushed downward on the limit support rod 33 due to its own weight and the weight of the bottom baffle plate 5. When the moving crossbeam 21 moves downward stably, the bottom baffle plate 5 will be pushed downward at a uniform and stable speed by pressing the push rod 23, and the bottom baffle plate 5 and the limit baffle plate 63 are supported by the movable support rod 66 and the second spring 67, so that the bottom baffle plate 5 pushes the limit baffle plate 63 to move downward at a uniform speed, and after the bottom baffle plate 5 is hit by the wooden rod 7, the bottom baffle plate 5 will suddenly apply pressure downward, so that the limit baffle plate 63 is fixed on the limit support rod 33 due to friction, and the bottom baffle plate 5 is supported by the limit baffle plate 63.
[0044] like Figures 5 to 8 As shown, the first fixing frame 61 is rotatably connected to the two ends of the bottom baffle plate 5, and a bayonet matching the locking plate 69 is provided on the inner side of the middle part of the first fixing frame 61 for limiting the locking plate 69. The upper end of the first fixing frame 61 is rotatably connected to the locking plate 69, and the transverse locking rod 62 is clamped in the inside of the limiting bayonet 45. The upper end of the folding push block 64 is rotatably connected to the bottom baffle plate 5, and the locking block 65 is slidably connected to the inner side of the locking plate 69. An opening is provided in the middle part of the locking plate 69 for releasing the sliding connection between the locking block 65 and the locking plate 69. A bent hook is provided at the bottom of the locking plate 69 to abut against the bottom of the limiting baffle plate 63 for limiting the limiting baffle plate 63.
[0045] The above scheme is adopted: by setting the first fixing frame 61 and the transverse locking rod 62, the first fixing frame 61 drives the transverse locking rod 62 to rotate, so that the transverse locking rod 62 moves out from the inside of the limiting clamping hole 45, and the limiting of the rectangular bracket 41 is released. By setting the folding push block 64, when the bottom baffle plate 5 is suddenly pressed down, the bottom baffle plate 5 moves down at this time, and the limiting baffle plate 63 is stuck in the middle of the limiting support rod 33 due to uneven force, so that the folding push block 64 is squeezed and folded, so the folding push block 64 extends toward the elastic limiting protrusion 68, pushing the elastic limiting protrusion 68 to move, and the locking block 65 and the locking plate 69 The design is that the locking block 65 limits the locking plate 69, so that the locking plate 69 can only move up and down. The opening set in the middle of the locking plate 69 makes it possible for the locking plate 69 to drop synchronously with the bottom baffle 5 when the bottom baffle 5 descends and the limiting baffle 63 is fixed. At this time, the opening is in correspondence with the locking block 65, so that the locking plate 69 will be squeezed and flipped outward by the elastic limiting protrusion 68, and then the locking plate 69 drives the elastic limiting protrusion 68 to flip outward. At the same time, a bent hook is set at the bottom of the locking plate 69, which can make the second spring 67 maintain a stable state of support between the limiting baffle 63 and the bottom baffle 5.
[0046] like Figures 5 to 8 As shown, the upper and lower ends of the movable support rod 66 pass through the bottom baffle 5 and the folding push block 64 respectively, the limit baffle 63 is slidably connected to the limit support rod 33, the locking block 65 is bent toward the elastic limit protrusion 68, and the locking block 65 is in conflict with the elastic limit protrusion 68, the elastic limit protrusion 68 is trapezoidal, and the elastic limit protrusion 68 is in conflict with the limit support rod 33, and the side of the elastic limit protrusion 68 away from the locking block 65 is in conflict with the locking plate 69, and a pair of second springs 67 are fixedly connected to the bottom baffle 5 and the limit baffle 63 respectively.
[0047] By adopting the above scheme: by setting the movable support rod 66 and the second spring 67, the bottom baffle 5 and the limit baffle 63 can be supported, so that the limit baffle 63 carries the bottom baffle 5, and the movable support rod 66 passes through the bottom baffle 5 and the folding push block 64 respectively, so that when the bottom baffle 5 is hit by the wood rod 7, it will move downward instead of being stuck by the movable support rod 66. At the same time, the second spring 67 plays a certain buffering role on the bottom baffle 5. The setting of the elastic limit protrusion 68 can push the card plate 69 to flip, so that the rectangular bracket 41 contacts the limit, and at the same time, the elastic limit protrusion 68 will be squeezed by the folding push block 64. The limit support rod 33 further strengthens the stability between the limit baffle 63 and the limit support rod 33, and can better bear the downward impact force of the bottom baffle 5.
[0048] like Figures 1 to 8 As shown, the present invention proposes a method for detecting the curvature of wood, comprising the following steps:
[0049] S1, drying the wood rod 7, and then using a woodworking machine to process the wood rod 7 to achieve a specified length, width, thickness and shape, and then placing the wood rod 7 on the top of the clamp seat 32 so that the middle of the wood rod 7 is perpendicular to the pressure sensing mechanism 22;
[0050] S2, controlling the moving crossbeam 21 to move downward, so that the pressure sensing mechanism 22 at the bottom of the moving crossbeam 21 squeezes the wood rod 7 to bend downward, and the pressure sensing mechanism 22 detects the curvature of the wood rod 7 and the pressure on the wood rod 7. At the same time, the moving crossbeam 21 squeezes the bottom baffle 5 and moves downward along the limit support rod 33 by pressing the push rod 23 downward until the wood rod 7 breaks;
[0051] S3, after the wood rod 7 breaks, a thrust force is generated downward from the middle, and the middle of the wood rod 7 squeezes the bottom baffle plate 5 to quickly move toward the limiting baffle plate 63, so that the bottom baffle plate 5 squeezes the folding push block 64 to bend, and the clamping block 65 squeezes the elastic limiting protrusion 68 to move toward the clamping plate 69. At the same time, the bottom baffle plate 5 drives the clamping plate 69 to move downward, so that the clamping block 65 moves to the opening in the middle of the clamping plate 69, and the elastic limiting protrusion 68 pushes the clamping plate 69 with the first fixing frame 61 to flip, so that the transverse clamping rod 62 flips and slides out from the bottom of the limiting bayonet 45, so that the sliding member 24 pushes the rectangular bracket 41 and the X-shaped elastic telescopic frame 42 to flip to both sides through the first spring 25, so that when the wood rod 7 breaks, the parts of the wood rod 7 pried up to the middle at both ends are blocked by the lower block 43;
[0052] It is worth noting that when testing wood, the shape of the wood rod 7 may not be the shape of a plate. In this case, the clamp seat 32 can be replaced with a clamp seat 32 of appropriate specifications as needed to ensure the accuracy and safety of the test.
