Detailed Implementation

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Homogeneity refers to the degree of consistency and uniformity of an object, material, or system in terms of structure, composition, properties, or performance.

[0028] like Figures 1-3As shown, a device for detecting the homogeneity of wood fibers includes a support platform 1. A support box 2 containing several wood fibers is fixed on the inner side of the support platform 1. Several detection mechanisms 3 are arranged sequentially along the length of the support platform 1 on the outer side of the support platform 1. Each detection mechanism 3 includes a balance 31 set on the support platform 1 and a beaker 32 located on the balance 31. Each beaker 32 contains an equal amount of water. The device also includes an adjustment mechanism 5. A clamping mechanism 4 for clamping wood fibers is fixedly set on the adjustment mechanism 5. The adjustment mechanism 5 can control the clamping mechanism 4 to clamp wood fibers at different positions inside the support box 2 and place them sequentially in beakers 32 at different positions.

[0029] The wood fibers contained in each position within the carrier box 2 are from the same batch.

[0030] Specifically, the initial volume of water in different beakers 32 is V1, and the mass of beakers 32 and water displayed on the corresponding balance 31 is M1. Wood fibers from different positions within the same batch are picked up by the clamping mechanism 4 and placed in different beakers 32. When the wood fibers are completely submerged in water, the final volume displayed in the different beakers 32 is recorded as V2, and the corresponding mass of the balance 31 is M2 (M2 is the mass of beakers 32, water, and wood fibers). (M2 - M1) / (V2 - V1) = ρ The density of wood fibers in different beakers is calculated. Firstly, it can detect whether the wood fibers in the same batch meet the homogeneity requirements. Secondly, by comparing the density with the density of specified standard wood fibers, it can determine whether the wood fibers in this batch meet the quality requirements.

[0031] Furthermore, after the wood fibers are completely submerged in water, pH test paper is placed in each beaker 32. The pH value of the wood fibers dissolved in water in different beakers is measured by the pH test paper to determine whether the wood fibers of the same batch meet the homogeneity and quality requirements.

[0032] This invention, through the cooperation of the detection mechanism 3, the clamping mechanism 4 and the adjustment mechanism 5, can calculate the density of wood fibers at different locations in the same batch, and can measure the pH value of wood fibers at different locations in the same batch, thereby detecting whether the wood fibers in the same batch meet the requirements of homogeneity and quality.

[0033] The adjustment mechanism 5 includes a longitudinal adjustment mechanism 51, a lateral adjustment mechanism 52, and a height adjustment mechanism 53. The lateral adjustment mechanism 52 is fixedly mounted on the longitudinal adjustment mechanism 51, the height adjustment mechanism 53 is fixedly mounted on the lateral adjustment mechanism 52, and a clamping mechanism 4 is fixedly mounted on the height adjustment mechanism 53. The longitudinal adjustment mechanism 51 controls the forward and backward movement of the clamping mechanism 4, the lateral adjustment mechanism 52 controls the left and right movement of the clamping mechanism 4, and the height adjustment mechanism 53 controls the up and down movement of the clamping mechanism 4.

[0034] The longitudinal adjustment mechanism 51 includes a support frame 511, a first lead screw assembly 512, and support blocks 513. The first lead screw assembly 512 is installed inside the support frame 511, and one support block 513 is installed on each side of the first lead screw assembly 512. A bearing platform 1 is installed on the top of the support frame 511.

[0035] The lateral adjustment mechanism 52 includes a second lead screw assembly 521 and a fixing block 522. The second lead screw assembly 521 is installed between two support blocks 513, and two fixing blocks 522 are installed on the second lead screw assembly 521.

[0036] The height adjustment mechanism 53 includes a third lead screw assembly 531 and a support block 532. The third lead screw assembly 531 is installed between two fixed blocks 522. The support block 532 is installed on the third lead screw assembly 531. The clamping mechanism 4 is installed on the support block 532.

[0037] The clamping mechanism 4 includes a clamping cylinder 41 and clamping parts 42 located at both ends of the clamping cylinder 41. The cylinder rod of the clamping cylinder 41 retracts, and the two clamping parts 42 move close to each other and can clamp the wood fibers inside the carrier box 2.

[0038] Specifically, the longitudinal adjustment mechanism 51, the transverse adjustment mechanism 52, and the height adjustment mechanism 53 enable the clamping mechanism 4 to move freely left and right, forward and backward, and up and down on the support platform 1, thereby facilitating the extraction of wood fibers from various positions within the support box 2 for homogeneity testing.

[0039] This invention achieves automatic clamping of wood fibers at various positions within the carrier box 2 by the clamping mechanism 4 through the longitudinal adjustment mechanism 51, the transverse adjustment mechanism 52, and the height adjustment mechanism 53. Compared with manual clamping, there are fewer interference factors, the stroke is controllable, and it is more convenient.

[0040] Furthermore, the water in beaker 32 can be replaced with a dye that can stain the wood fibers. The stained wood fibers are then extracted and examined under a microscope or scanning electron microscope (SEM). The stained wood fibers are more convenient to observe under a microscope or scanning electron microscope (SEM) to determine their length, diameter, and morphology, and can be used to detect the homogeneity and quality of wood fibers from different locations in the same batch.

[0041] This invention, through the cooperation of the detection mechanism 3, the clamping mechanism 4, and the adjustment mechanism 5, can achieve the dyeing of wood fibers at different locations in the same batch, thereby facilitating the observation of the length, diameter, and morphology of the wood fibers, and can be used to detect whether the wood fibers in the same batch meet the requirements of homogeneity and quality.

[0042] When the wood fibers held in different locations within the carrier box 2 are from different batches, multiple testing mechanisms 3 are established. The clamping mechanism 4 picks up different batches of wood fibers and places them into the testing mechanism 3. This allows for the acquisition of the density and pH value of different batches of wood fibers, observation of their shape, and comparison of their performance, providing a control group. This enables a more objective assessment of whether the quality of different groups of wood fibers meets the specified homogeneity requirements, while also improving testing efficiency.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
