Description

Technical Field

[0001] This disclosure relates to the field of brush filament density measurement technology, and more specifically, to a brush roller filament density measuring device. Background Technology

[0002] In the metallurgical industry, brush rollers are crucial cleaning tools, and their performance directly impacts the operational efficiency and product quality of steel plate and strip production lines. Brush filament density is a key indicator of brush roller performance; too low a density will affect the cleaning effect. During the production and repair of brush rollers, operators and quality inspectors need to constantly monitor the filament density to ensure effective cleaning. However, existing methods for measuring filament density are rather cumbersome. Utility Model Content

[0003] To overcome the cumbersome nature of existing methods for measuring brush filament density, this invention provides a brush roller filament density measuring device.

[0004] To achieve the above objectives, this disclosure provides a brush roller filament density measuring device, comprising:

[0005] The base is equipped with a sliding cavity;

[0006] A slider, the two ends of which are slidably connected to the two side walls of the sliding cavity, respectively;

[0007] The lead screw is threadedly connected to the base and the slider, respectively;

[0008] A positioning block is fixed on the slider and extends out of the upper opening of the sliding cavity;

[0009] A barrier, positioned circumferentially around the upper opening of the sliding cavity, and enclosing the positioning block to form a clamping cavity for clamping the brush bristles; and

[0010] The graduation lines are set on the wall of the lower opening of the sliding cavity.

[0011] Optionally, the inner side of the positioning block is flush with the inner side of the slider, and there are two scale lines, which are respectively located on the left and right sides of the slider.

[0012] Optionally, the sliding cavity is provided with a step, and the left and right sides of the slider are provided with protrusions and are slidably connected to the step, and the protrusions extend along the length direction of the slider.

[0013] Optionally, the brush roller filament density measuring device further includes a mounting plate, which is fixed on the base, and the enclosure is fixed on the mounting plate. The mounting plate is provided with a clearance cavity for avoiding the slider, and the clearance cavity is connected to the sliding cavity. The two ends of the slider are in contact with the side walls of the clearance cavity.

[0014] Optionally, the enclosure includes three fixing blocks, which are respectively located in three directions of the upper opening of the sliding cavity.

[0015] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0016] Rotate the lead screw to drive the slider and move the positioning block, aligning the end of the positioning block furthest from the lead screw with the starting point of the scale line. Flip the density measuring device to bring the positioning block and the guard close to the brush roller. Then, place the positioning block and the guard stably on the brush roller. At this point, the brush bristles extend into the clamping cavity. Rotate the lead screw so that the positioning block can compress the brush bristles until the lead screw can no longer rotate. Record the scale value at the position where the positioning block stops. Calculate the brush bristle density according to the formula: (Cross-sectional area of ​​1 square centimeter of compressed brush bristles ÷ 1 square centimeter) × 100%. This allows production and quality control personnel to monitor the brush bristle density at any time during the production and repair of brush rollers, improving product quality and production efficiency.

[0021] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0022] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "front," "rear," "left," and "right" are used for ease of description based on the drawing orientations of the corresponding figures, while "inner" and "outer" are defined based on the contours of the corresponding components themselves. Terms such as "first" and "second" used in this disclosure are used to distinguish one element from another and do not have sequential or importance implications. Furthermore, when the following description refers to the figures, unless otherwise indicated, the same numbers in different figures represent the same or similar elements.

[0023] Please see Figure 1 and Figure 2 This disclosure provides a brush roller filament density measuring device. The brush roller is prior art and will not be described in detail here. The measuring device may include a base 1, a slider 3, a lead screw 5, a positioning block 9, a retaining wall 6, and a scale line 8. The base 1 has a sliding cavity 11. The two ends of the slider 3 are slidably connected to the side walls of the sliding cavity 11, respectively, meaning the left and right side walls of the sliding cavity 11 can restrict the rotation of the slider 3. The lead screw 5 is threadedly connected to the base 1 and the slider 3. The positioning block 9 can be fixed to the slider 3 by a snap-fit ​​or bolt and extends out of the upper opening 12 of the sliding cavity 11. The retaining wall 6 is disposed circumferentially around the upper opening 12 of the sliding cavity 11, meaning the inner side of the retaining wall 6 is aligned circumferentially with the opening wall of the upper opening 12. The retaining wall 6 and the positioning block 9 together form a clamping cavity 61 for clamping brush filaments (not shown in the figure). The scale line 8 is disposed on the opening wall of the lower opening 13 of the sliding cavity 11. The inner side of the retaining wall 6 refers to the side closer to the clamping cavity 61.

[0024] Understandably, rotating the lead screw 5 drives the slider 3 to move the positioning block 9, aligning the end of the positioning block 9 furthest from the lead screw 5 with the starting point of the scale line 8. The density measuring device is then flipped so that the positioning block 9 and the retaining wall 6 are close to the brush roller. Next, the positioning block 9 and the retaining wall 6 are placed stably on the brush roller. At this point, the brush bristles extend into the clamping cavity 61. Rotating the lead screw 5 allows the positioning block 9 to squeeze the brush bristles until the lead screw 5 can no longer rotate. The scale value at the position where the positioning block 9 stops is recorded. For example, if the length of the scale line 8 is 15 cm, and the scale line 8 at the position where the positioning block 9 stops is 7 cm, then the length of the clamping cavity 61 = 15 - 7 = 8 cm. Meanwhile, since the width between the inner sides of the left and right side panels of the enclosure 6 is a known quantity, for example, 3 cm, the area of ​​the clamping cavity 61 is equal to the cross-sectional area of ​​the brush filament after compression, which is 8 × 3 = 24 square centimeters. The brush filament density can be calculated according to the formula: (cross-sectional area of ​​1 square centimeter of brush filament after compression ÷ 1 square centimeter) × 100%. This allows production and quality control personnel to check the brush filament density at any time during the production and repair of the brush roller, thereby improving product quality and production efficiency.

[0025] In one implementation, please refer to Figure 2The inner side of the positioning block 9 is flush with the inner side of the slider 3. By observing the position of the inner side of the slider 3 on the scale line 8, the user can indirectly know the position of the inner side of the positioning block 9 on the scale line 8, making it easy for the user to quickly determine the location of the inner side of the positioning block 9. There are two scale lines 8, which are located on the left and right sides of the slider 3 respectively, ensuring accurate determination of the location of the inner side of the positioning block 9.

[0026] In one implementation, please refer to Figure 1 The sliding cavity 11 is provided with a step, and the left and right sides of the slider 3 are provided with protrusions and are slidably connected to the step. The protrusions extend along the length of the slider 3, and the step can be used to support the protrusions without relying solely on the lead screw 5 to provide upward support force for the slider 3.

[0027] In one implementation, please refer to Figure 1 The brush roller filament density measuring device also includes a mounting plate 4, which is fixed on the base 1. The enclosure 6 is fixed on the mounting plate 4. The mounting plate 4 is provided with a clearance cavity 41 for avoiding the slider 3. The clearance cavity 41 is connected to the sliding cavity 11. The two ends of the slider 3 are in contact with the two side walls of the clearance cavity 41 to ensure that the slider 3 will not rotate when the screw 5 drives the slider 3 to move.

[0028] In one implementation, please refer to Figure 1 The enclosure 6 includes three fixing blocks, which are located in three directions of the upper opening 12 of the sliding cavity 11. Specifically, one of the fixing blocks and the positioning block 9 are located in the front and rear directions of the sliding cavity 11, respectively, and the other two fixing blocks are located on the front side and the left and right sides of the upper opening 12 of the sliding cavity 11. The fixing blocks and the positioning blocks 9 can have the same shape and size, which is convenient for the enterprise to process and manufacture.

[0029] In one implementation, please refer to Figure 1 To prevent wear between the base 1 and the lead screw 5, the brush roller filament density measuring device also includes a stop block 2, which is fixed to the base 1. The lead screw 5 is threadedly connected to the stop block 2, meaning the lead screw 5 is threadedly connected to the base 1 through the stop block 2. Of course, in other embodiments, the lead screw 5 can be directly threaded to the base 1.
