Description

Technical Field

[0001] This invention relates to a testing device, and more particularly to a strength-increasing carbonized bamboo strip toughness testing device. Background Technology

[0002] After simple processing, carbonized bamboo strips need to be spliced ​​into bamboo boards for use. Therefore, the toughness of carbonized bamboo strips is directly related to the quality of the bamboo boards in the later stage. Thus, it is necessary to extract a portion of a batch of carbonized bamboo strips for toughness testing.

[0003] Chinese patent CN111426577A discloses a bamboo strip toughness testing device, including a rectangular base. A support column is located at one end of the base, and a slide is located at the other end of the base facing the support column. A slider is installed within the slide and connected to a push-pull cylinder at the base's end. A second support column is mounted on the slider. Both the second and first support columns have opposing contact blocks on their opposite surfaces, with the opposing surfaces of the two contact blocks concave inwards towards the center. The slider is connected to the push-pull cylinder, and a scale plate with vertical and horizontal graduations is located on one side of the base. This device digitizes and visualizes the bamboo strip toughness data, allowing researchers to better compare the toughness of different bamboo materials and improve testing efficiency.

[0004] Although the aforementioned patent can perform toughness tests on bamboo strips, it cannot perform toughness tests on bamboo strips in a progressively increasing manner, which may lead to the uniformity of toughness tests on carbonized bamboo strips and affect the effectiveness of toughness tests.

[0005] Therefore, there is a need for a strength-increasing toughness testing device for carbonized bamboo strips that can progressively increase the toughness of the bamboo strips, avoiding the limitations of single-method toughness testing and providing good testing results. Summary of the Invention

[0006] To overcome the shortcomings of traditional toughness testing devices, which, while capable of testing bamboo strips, cannot progressively increase the toughness of bamboo strips, leading to the uniformity of toughness testing and affecting the effectiveness of toughness testing, this invention provides a strength-increasing toughness testing device for carbonized bamboo strips that can progressively increase the toughness of bamboo strips, avoiding the uniformity of toughness testing of carbonized bamboo strips and providing better testing results.

[0007] This invention is achieved through the following technical means:

[0008] A strength-increasing type carbonized bamboo strip toughness testing device includes a housing, a sliding door, a horizontal mounting frame, a guide shaft, a sleeve, a hollow hexagonal rod, a hexagonal T-shaped top block, and a vertical spring. The sliding door is slidably connected to the front side of the housing, blocking the opening of the housing. A hollow hexagonal rod is fixed to the center of the top of the housing. A hexagonal T-shaped top block for testing the toughness of the carbonized bamboo strip is slidably connected inside the hollow hexagonal rod. A vertical spring connects the top of the hexagonal T-shaped top block to the top of the hollow hexagonal rod. The lower parts of the left and right sides of the housing are connected by a vertical spring. The enclosure is symmetrically fixed with horizontal mounting brackets at the front and back. Each of the four horizontal mounting brackets is rotatably connected to a guide shaft in the middle. A sleeve is fixed between the inner ends of the two guide shafts on the front side, and a sleeve for placing carbonized bamboo strips is also fixed between the inner ends of the two guide shafts on the rear side. It also includes a drive device and an incrementing device. A drive device is set between the enclosure and the hollow hexagonal rod to drive the hexagonal T-shaped top block to move downward. The drive device contacts the hexagonal T-shaped top block. An incrementing device is set between the enclosure and the drive device to continuously increase the force for testing the toughness of the carbonized bamboo strips.

[0009] Further explanation: The drive device includes a sliding frame, a locking frame, locking rods, a return spring, an electric push rod, and a connecting frame. The lower left and right sides of the hexagonal T-shaped top block have symmetrical locking holes. The sliding frame is slidably fitted onto the outer side of the hollow hexagonal rod. The locking frame is slidably connected to the lower left and right sides of the sliding frame. The locking rods for moving the hexagonal T-shaped top block downwards are embedded and slidably connected at both ends of the inner side of the locking frame. The inner ends of the four locking rods are located in the four locking holes respectively. The outer ends of the four locking rods are connected to the inner side of the locking frame with a return spring. The connecting frame is slidably connected to the left and right sides of the housing. The inner side of the connecting frame is fixedly connected to the upper part of the left and right sides of the sliding frame respectively. The lower middle part of the left and right sides of the housing is fixedly connected to an electric push rod. The telescopic rod ends of the left and right electric push rods are fixedly connected to the outer ends of the left and right connecting frames respectively.

[0010] Further explanation: The incrementing device includes a guide slide, a slide spring, a long rack, a ratchet, a crossbar, a one-way spur gear, a first ratchet, and a horizontal spring. Guide slides for moving the positioning frame outwards are slidably connected to both the left and right sides of the housing. The left and right guide slides are slidably mounted on the left and right positioning frames. Slide springs connect the upper parts of the left and right guide slides to the inner side of the housing. Long racks are fixedly connected to the upper inner sides of the left and right guide slides. A crossbar is slidably threaded through the upper front side of the housing. Horizontal springs are symmetrically connected between the rear inner side of the crossbar and the front inner side of the housing. One-way spur gears for moving the long rack downwards are symmetrically rotatably connected to the rear side of the crossbar. The left and right one-way spur gears mesh with the left and right long racks respectively. A first ratchet is fixedly connected to the center of the rear side of the left and right one-way spur gears. Rats are fixedly connected to the upper parts of the left and right outer sides of the positioning frame, and the left and right ratches correspond to the left and right first ratches respectively.

[0011] Further explanation includes a locking device for limiting the carbonized bamboo strips. The locking device includes a second ratchet, a U-shaped frame, a contact frame, ratchet teeth, a reciprocating spring, a compression spring, and a drive frame. The second ratchet is fixed to both ends of the rear guide shaft. The U-shaped frames are symmetrically fixed to the upper rear side of the box. The contact frame is slidably fitted between the left and right U-shaped frames. Four compression springs are connected between the rear side of the contact frame and the rear side of the box. The compression springs are fitted onto the U-shaped frames. The ratchet teeth for preventing the second ratchet from rotating in the right direction are symmetrically slidably connected to the lower front side of the contact frame. The ratchet teeth on the left and right sides correspond to the second ratchet on the left and right sides, respectively. The rear ends of the ratchet teeth on the left and right sides are connected to the inner side of the contact frame with reciprocating springs. The drive frame for limiting the contact frame is fixed to the upper rear side of the hexagonal T-shaped top block. The drive frame is in contact with the contact frame.

[0012] Further explanation includes a pushing device for moving the crossbar. The pushing device includes a U-shaped mounting bracket, a roller, an L-shaped bracket, and a guide bracket. The U-shaped mounting bracket is fixed to the middle of the inner rear side of the crossbar. The roller is rotatably connected between the front parts of the left and right sides of the U-shaped mounting bracket. The L-shaped bracket is fixed to the upper part of the rear side of the sliding door. The L-shaped bracket is in contact with the roller. The guide bracket for moving the roller forward is fixed to the inner side of the L-shaped bracket. The lower part of the front side of the guide bracket has a locking groove for limiting the roller.

[0013] Further explanation includes an adaptive mechanism for bending carbonized bamboo strips. The adaptive mechanism includes a hinge frame and an arc-shaped rubber plate. The lower parts of the front and rear sides of the hexagonal T-shaped top block are rotatably connected to the hinge frame. The outer ends of the front and rear hinge frames are rotatably connected to the arc-shaped rubber plate for more stable bending of the carbonized bamboo strips.

[0014] Further explanation includes mounting blocks and guide wheels. Mounting blocks are symmetrically fixed to the top and bottom of the front and rear side frames. A guide wheel for guiding the carbonized bamboo strips is rotatably connected between the two mounting blocks on each side. The guide wheel runs through the frame.

[0015] Further explanation includes the presence of baffles. Baffles are fixedly installed on both the left and right connecting frames to block foreign objects. The left and right baffles are located outside the box.

[0016] The significant advancement of this invention lies in:

[0017] 1. Place the carbonized bamboo strip between the two frames, start the drive device to move the hexagonal T-shaped top block downwards. The downward movement of the hexagonal T-shaped top block will bend the carbonized bamboo strip for toughness testing. Through the action of the incremental device, the test intensity can be increased with each test, thus improving the test intensity and the effect of the toughness test of the carbonized bamboo strip.

[0018] 2. Under the action of the locking device, whenever the hexagonal T-shaped top block moves upward and resets to disengage from the carbonized bamboo strip, the locking device can limit the guide shaft, thus limiting the carbonized bamboo strip. In this way, the carbonized bamboo strip is prevented from springing back to reset and contacting the hexagonal T-shaped top block, which would cause wear.

[0019] 3. Under the action of the pushing device, whenever the operator pulls the slide upward, the pushing device will drive the crossbeam to move forward. In this way, there is no need for a person to pull the crossbeam backward to disengage the one-way column gear from the long rack, which is convenient and quick. Attached Figure Description

[0040] Example

[0041] A strength-increasing type carbonized bamboo strip toughness testing device includes a housing 1, a sliding door 2, a horizontal mounting frame 3, a guide shaft 4, a sleeve 41, a hollow hexagonal rod 5, a hexagonal T-shaped top block 6, a vertical spring 7, a driving device 8, and an increasing device 9. (Please refer to...) Figures 1-12As shown, a sliding door 2 is slidably connected to the front side of the box 1, blocking the opening of the box 1. A hollow hexagonal rod 5 is fixed to the middle of the top inside the box 1. A hexagonal T-shaped top block 6 is slidably connected inside the hollow hexagonal rod 5. When the hexagonal T-shaped top block 6 moves downward and contacts the carbonized bamboo strip, the hexagonal T-shaped top block 6 can perform a toughness test on the carbonized bamboo strip. A vertical spring 7 is connected between the top of the hexagonal T-shaped top block 6 and the top inside the hollow hexagonal rod 5. Horizontal mounting brackets 3 are symmetrically fixed to the lower part of the left and right sides inside the box 1. The four horizontal mounting brackets 3 are rotatably connected in the middle. There is a guide shaft 4. The inner ends of the two guide shafts 4 on the front side are connected by bolts to install a sleeve 41. The inner ends of the two guide shafts 4 on the rear side are also connected by bolts to install a sleeve 41. The sleeve 41 is used to place the carbonized bamboo strips. A drive device 8 is set between the box body 1 and the hollow hexagonal rod 5. The drive device 8 is in contact with the hexagonal T-shaped top block 6. When the drive device 8 is operating, the drive device 8 can drive the hexagonal T-shaped top block 6 to move downward. An increment device 9 is set between the box body 1 and the drive device 8. The increment device 9 can continuously increase the force for testing the toughness of the carbonized bamboo strips.

[0042] The drive unit 8 includes a sliding frame 81, a locking frame 82, a locking rod 83, a return spring 84, an electric push rod 86, and a connecting frame 87. Please refer to [link / reference]. Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the hexagonal T-shaped top block 6 has symmetrical locking holes 85 on the lower left and right sides. The hollow hexagonal rod 5 is slidably fitted with a sliding frame 81. The lower left and right sides of the sliding frame 81 are slidably connected with locking frames 82. The inner ends of the locking frames 82 on both sides are slidably connected with locking rods 83. The inner ends of the four locking rods 83 are respectively located in the four locking holes 85. When the locking rods 83 move downward, they can drive the hexagonal T-shaped top block 6 to move downward. The outer ends of the four locking rods 83 are connected to the inner side of the locking frame 82 with a return spring 84. The left and right sides of the box body 1 are slidably connected with connecting frames 87. The inner sides of the connecting frames 87 on both sides are respectively connected to the upper part of the left and right sides of the sliding frame 81 by bolts. The lower middle part of the left and right sides of the box body 1 is installed with electric push rods 86 by bolts. The telescopic rod ends of the electric push rods 86 on both sides are respectively fixedly connected to the outer ends of the connecting frames 87 on both sides.

[0043] The incrementing device 9 includes a guide carriage 91, a carriage spring 92, a long rack 93, a ratchet 94, a crossbar 95, a one-way spur gear 96, a first ratchet 961, and a horizontal spring 97. (See also...) Figure 2 , Figure 11 and Figure 12 As shown, guide slides 91 are slidably connected to the left and right sides of the housing 1. The left and right guide slides 91 are slidably mounted on the left and right side mounting brackets 82. When the mounting brackets 82 move downward to the appropriate position, the guide slides 91 can drive the mounting brackets 82 to move outward. Slide springs 92 are connected between the upper part of the left and right guide slides 91 and the inner side of the housing 1. Long racks 93 are fixed to the upper part of the inner side of the left and right guide slides 91. A crossbeam 95 is slidably connected to the upper front side of the housing 1. The rear inner side of the crossbeam 95 is connected to the housing. A horizontal spring 97 is symmetrically connected between the inner front side and the cross frame 95. A one-way spur gear 96 is symmetrically rotatably connected to the rear side of the cross frame 95. The one-way spur gears 96 on the left and right sides mesh with the long racks 93 on the left and right sides respectively. When the one-way spur gear 96 rotates, the one-way spur gear 96 can drive the long rack 93 to move downward. A first ratchet 961 is fixedly connected to the center of the rear side of the one-way spur gears 96 on both sides. A ratchet 94 is fixedly connected to the upper part of the left and right sides of the outer side of the locking frame 82. The ratchet 94 on the left and right sides corresponds to the first ratchet 961 on the left and right sides respectively.

[0044] First, the operator pulls the sliding door 2 upwards to avoid blocking the opening of the box 1. Then, the carbonized bamboo strip is placed between the two sleeves 41 from front to back. The sliding door 2 is then pulled downwards to reset, and the drive device 8 is activated. The drive device 8 moves the hexagonal T-shaped top block 6 downwards, stretching the vertical spring 7. The hexagonal T-shaped top block 6 moves downwards and contacts the carbonized bamboo strip, bending it. As the middle of the carbonized bamboo strip bends downwards, both ends slide within the two sleeves 41, causing the sleeves 41 to tilt and swing inwards. This tests the toughness of the carbonized bamboo strip. When the drive device 8 moves downwards to the appropriate position, the increment device 9 operates, causing the drive device 8 to disengage from the hexagonal T-shaped top block 6. Due to the action of the vertical spring 7, the hexagonal T-shaped top block 6 moves upwards to reset and disengage from the carbonized bamboo strip, which then springs back to a horizontal state. The drive device 8 is then activated again to move upwards to reset. The upward movement causes the incrementing device 9 to move downward a certain distance, while the driving device 8 moves upward to reset and continue contacting the hexagonal T-shaped top block 6. The driving device 8 is then activated again, causing the hexagonal T-shaped top block 6 to move downward again, bending the carbonized bamboo strip. Because the incrementing device 9 has moved downward a certain distance, the driving device 8 bends the carbonized bamboo strip at a larger angle, improving the toughness test effect. This process is repeated, increasing the bending angle each time the hexagonal T-shaped top block 6 bends the carbonized bamboo strip, further enhancing the toughness test effect. After the toughness test is completed, the driving device 8 is turned off, the incrementing device 9 is pulled to reset, and the sliding door 2 is pulled upward to a suitable position. The tested carbonized bamboo strip is removed, and a new carbonized bamboo strip is placed in. Once all the carbonized bamboo strips to be sampled have been tested, their condition can be checked. If the carbonized bamboo strip has cracked, it indicates that the quality is unqualified; otherwise, it is qualified.

[0045] After the carbonized bamboo strip is placed, the telescopic rods of the electric push rods 86 on both sides are activated to shorten, causing the connecting frames 87 on both sides to move downwards. The downward movement of the connecting frames 87 causes the sliding frame 81 to move downwards, which in turn causes the locking frames 82 on both sides to move downwards. The locking frames 82 slide on the increasing device 9, causing the four locking rods 83 to move downwards. The four locking rods 83 move downwards through the four locking holes 85, causing the hexagonal T-shaped top block 6 to move downwards. The hexagonal T-shaped top block 6 bends the carbonized bamboo strip for a toughness test. When the locking frames 82 on both sides move downwards to the appropriate position, the increasing device 9 causes the locking frames 82 on both sides to move outwards. The outward movement of the locking frames 82 causes the four locking rods 83 to move outwards. When 83 moves outward and disengages from the four locking holes 85, due to the action of the vertical spring 7, the hexagonal T-shaped top block 6 moves upward and resets, causing the four locking holes 85 to move upward and reset. At this time, the extension of the electric push rods 86 on both sides is activated, causing the connecting brackets 87 on both sides to move upward and reset. The locking brackets 82 on both sides also move upward and reset. The increment device 9 causes the locking brackets 82 on both sides to move inward and reset. The upward movement and reset of the locking brackets 82 on both sides causes the four locking rods 83 to reset. The four locking rods 83 move upward and contact the hexagonal T-shaped top block 6. The hexagonal T-shaped top block 6 causes the four locking rods 83 to move outward, and the four reset springs 84 are compressed. When the four locking rods 83 are reset and correspond to the four locking holes 85, due to the action of the four reset springs 84, the four locking rods 83 move inward and reset, inserting into the four locking holes 85.

[0046] When the telescopic rods of the left and right electric push rods 86 shorten, the sliding frame 81 moves downward, also causing the left and right ratchet bars 94 to move downward. The left and right ratchet bars 94 slide downward across the first ratchet wheels 961 on the left and right sides. The left and right locking frames 82 move downward and slide within the left and right guide slides 91. Then, when the hexagonal T-shaped top block 6 moves downward and bends the carbonized bamboo strip, the left and right locking frames 82 contact the inclined surfaces of the left and right guide slides 91. The left and right guide slides 91 drive the left and right locking frames 82 to move outward, which causes the four locking rods 83 to move outward and disengage from the four locking holes 85. The hexagonal T-shaped top block 6 moves upward and resets. At this time, the telescopic rods of the left and right electric push rods 86 are activated to extend. The left and right locking frames 82 move upward and disengage from the inclined surfaces of the left and right guide slides 91. The left and right guide slides 91 drive the left and right locking frames 82 to move inward and reset, which causes the four locking rods 83 to move inward and reset. The sliding frame 81 also drives the left and right ratchet bars 94 to move upward. The left and right ratchet bars 94 move upward and engage with the left and right first ratchet wheels 961. The left and right ratchet bars 94 drive the left and right first ratchet wheels 961 to rotate. The rotation of the left and right first ratchet wheels 961 drives the left and right one-way spur gears 96 to rotate. The rotation of the left and right one-way spur gears 96 drives the left and right long racks 93 to move downward. The downward movement of the left and right long racks 93 drives the left and right guide slides 91 to move downward. The left and right slide springs 92 are compressed. The left and right ratchet bars 94 return to their original position and disengage from the left and right first ratchet wheels 961. Due to the action of the one-way spur gears 96, the guide slides 91 are prevented from moving upward and returning to their original position. This process is repeated. When the hexagonal T-shaped top block 6 bends the carbonized bamboo strip again, the left and right guide slides 91 have moved downward a certain distance, which delays the locking frame 82 from being pulled outward. This allows the hexagonal T-shaped top block 6 to bend the carbonized bamboo strip at a larger angle. After the toughness test of the carbonized bamboo strip is completed, the crossbeam 95 is pulled forward, compressing the horizontal springs 97 on both sides. The forward movement of the crossbeam 95 causes the one-way spur gears 96 on both sides to move forward and disengage from the long racks 93 on both sides. Due to the action of the slide springs 92 on both sides, the guide slides 91 on both sides move upward and reset, causing the long racks 93 on both sides to move upward and reset. Releasing the crossbeam 95 causes it to move backward and reset, causing the one-way spur gears 96 on both sides to move backward and reset, re-engaging with the long racks 93 on both sides. This allows the bending angle to increase incrementally.

[0047] It also includes a locking device 10, which comprises a second ratchet 101, a U-shaped bracket 102, a contact bracket 103, a ratchet 104, a reciprocating spring 105, a compression spring 106, and a drive bracket 107. Please refer to [link / reference needed]. Figure 2 , Figure 13 , Figure 14 and Figure 15As shown, the left and right ends of the rear guide shaft 4 are fixed with second ratchet 101. The upper part of the rear side of the housing 1 is symmetrically connected by welding to the left and right sides with U-shaped frame 102. The left and right sides of the U-shaped frame 102 are slidably fitted with contact frame 103. Four compression springs 106 are connected between the rear side of the contact frame 103 and the rear side of the housing 1. The compression springs 106 are fitted on the U-shaped frame 102. The lower part of the front side of the contact frame 103 is symmetrically connected with ratchet 104. The left and right sides of the ratchet 104 correspond to the left and right sides of the second ratchet 101 respectively. The ratchet 104 is used to prevent the second ratchet 101 from rotating in the forward direction. The rear ends of the left and right sides of the ratchet 104 are connected to the inner side of the contact frame 103 with reciprocating springs 105. The upper part of the rear side of the hexagonal T-shaped top block 6 is connected by welding to the drive frame 107. The drive frame 107 contacts the contact frame 103 and can limit the contact frame 103.

[0048] It also includes a pushing device 11, which comprises a U-shaped mounting bracket 111, a roller 112, an L-shaped bracket 113, and a guide bracket 114. Please refer to [link / reference needed]. Figure 2 , Figure 13 and Figure 14 As shown, a U-shaped mounting bracket 111 is installed in the middle of the inner rear side of the cross frame 95 by welding. Rollers 112 are rotatably connected between the front parts of the left and right sides of the U-shaped mounting bracket 111. An L-shaped bracket 113 is fixed to the upper rear side of the sliding door 2. The L-shaped bracket 113 contacts the roller 112. A guide bracket 114 is fixed to the inner side of the L-shaped bracket 113. When the guide bracket 114 moves upward and contacts the roller 112, the guide bracket 114 can drive the roller 112 to move forward. A locking groove 115 is opened on the lower front side of the guide bracket 114. When the roller 112 is inserted into the locking groove 115, the locking groove 115 can limit the roller 112.

[0049] Initially, the four compression springs 106 are in a compressed state. When the hexagonal T-shaped top block 6 moves downward, it also drives the drive frame 107 downward. The drive frame 107 does not limit the contact frame 103. Due to the action of the four compression springs 106, the contact frame 103 moves forward, which drives the left and right ratchet teeth 104 to move forward through the reciprocating springs 105 on both sides. The left and right ratchet teeth 104 engage with the left and right second ratchet wheels 101. Then, when the hexagonal T-shaped top block 6 bends the carbonized bamboo strip for toughness testing, the bending of the carbonized bamboo strip causes the front and rear sleeves 41 to rotate. The rotation of the front and rear sleeves 41 causes the guide shaft 4 to rotate. The rotation of the rear guide shaft 4 causes the left and right second ratchet wheels 101 to rotate. The left and right second ratchet wheels 101 slide on the left and right ratchet teeth 104. When the hexagonal T-shaped top block 6 moves upward and resets, it disengages from the carbonized bamboo strip. The ratchet teeth 104 on both sides limit the second ratchet wheels 101 on both sides. The second ratchet wheels 101 limit the rear guide shaft 4. The rear guide shaft 4 stops passing the rear sleeve 41, thus limiting the carbonized bamboo strip. The hexagonal T-shaped top block 6 moves upward, causing the drive frame 107 to move upward and reset. The reset of the drive frame 107 causes the contact frame 103 to move backward and reset. The four compression springs 106 are compressed. The reset of the contact frame 103 drives the ratchet teeth 104 to move backward and reset through the reciprocating springs 105 on both sides. The ratchet teeth 104 on both sides move backward and reset, disengaging from the second ratchet wheels 101 on both sides. The second ratchet wheels 101 on both sides stop being limited. The carbonized bamboo strip springs back to the initial state, causing the front and rear sleeves 41 to rotate in the opposite direction and reset. The reset of the front and rear sleeves 41 causes the front and rear guide shafts 4 to rotate in the opposite direction and reset. The reset of the two rear guide shafts 4 causes the second ratchet wheels 101 on both sides to rotate in the opposite direction and reset. This avoids the carbonized bamboo strip rebounding and resetting, which could lead to contact with the hexagonal T-shaped top block 6 and cause wear.

[0050] When the operator pulls the sliding door 2 upwards, the upward movement of the sliding door 2 also moves the L-shaped bracket 113 upwards. The upward movement of the L-shaped bracket 113 moves the guide bracket 114 upwards, which in turn moves the locking groove 115 upwards. The upward movement of the guide bracket 114 moves the roller 112 forwards, which in turn moves the U-shaped mounting bracket 111 forwards. The forward movement of the U-shaped mounting bracket 111 moves the crossbeam 95 forwards, causing the one-way column gears 96 on both sides to move forwards and disengage from the long racks 93 on both sides. The guide slides 91 on both sides then move upwards and reset. At this point, the lock... The locking groove 115 contacts the roller 112, limiting the roller 112. The roller 112, via the U-shaped mounting bracket 111, limits the crossbeam 95. When the operator pulls the sliding door 2 downward to reset, the sliding door 2, via the L-shaped bracket 113, drives the guide bracket 114 downward to reset. The reset of the guide bracket 114 causes the locking groove 115 to reset and disengage from the roller 112. The locking groove 115 stops limiting the roller 112, and the reset of the crossbeam 95, via the U-shaped mounting bracket 111, drives the roller 112 to move backward to reset, thus allowing the one-way gears 96 on both sides to continue meshing with the long racks 93 on both sides. In this way, there is no need for manual pulling of the crossbeam 95 to disengage the one-way gears 96 from the long racks 93, making it convenient and quick.

[0051] It also includes an adaptive mechanism 12, which includes a hinge frame 121 and an arc-shaped rubber plate 122. Please refer to [link / reference]. Figure 2 and Figure 16 As shown, the lower parts of the front and rear sides of the hexagonal T-shaped top block 6 are rotatably connected to hinge frames 121, and the outer ends of the front and rear hinge frames 121 are rotatably connected to an arc-shaped rubber plate 122. The arc-shaped rubber plate 122 is used to make the hexagonal T-shaped top block 6 more stable in bending the carbonized bamboo strip.

[0052] It also includes mounting block 13 and guide wheel 14, please refer to Figure 16 As shown, mounting blocks 13 are symmetrically fixed to the top and bottom of the front and rear side frames 41. Guide wheels 14 are rotatably connected between the two mounting blocks 13 on each side. The guide wheels 14 pass through the frame 41. When the carbonized bamboo strip is placed into the frame 41, the guide wheels 14 can guide the carbonized bamboo strip.

[0053] It also includes a shield 15, please refer to Figure 17 and Figure 18 As shown, baffles 15 are fixedly mounted on the connecting frames 87 on both the left and right sides. The baffles 15 are located outside the box 1 and are used to block foreign objects.

[0054] When the hexagonal T-shaped top block 6 moves downward, it also drives the two hinged frames 121 to move downward. The downward movement of the two hinged frames 121 causes the curved rubber plate 122 to move downward, contacting the carbonized bamboo strip. The hexagonal T-shaped top block 6, through the curved rubber plate 122, bends the carbonized bamboo strip for a toughness test, ensuring the curved rubber plate 122 adheres tightly to the carbonized bamboo strip. When the hexagonal T-shaped top block 6 moves upward to reset, the reset mechanism, via the two hinged frames 121, drives the curved rubber plate 122 upward to reset. This close contact with the bent carbonized bamboo strip allows for better bending of the bamboo strip.

[0055] When the operator moves the carbonized bamboo strip between the front and rear side sleeves 41, the movement of the carbonized bamboo strip drives all the guide wheels 14 to rotate, and the rotation of all the guide wheels 14 guides the carbonized bamboo strip. In this way, the carbonized bamboo strip can be smoothly placed into the sleeve 41.

[0056] When the connecting frame 87 moves, it also moves the baffle plate 15, which blocks the connection between the connecting frame 87 and the housing 1. This prevents foreign objects from blocking the connection between the connecting frame 87 and the housing 1.
