Description

Technical Field

[0001] This application relates to the field of roller brush testing technology, and in particular to a roller brush testing device. Background Technology

[0002] In actual use, the fabric of the roller brush not only suffers wear and tear due to friction with the wall, but also pills and flattens out with repeated brushing. Abrasion resistance tests on the fabric are considered complete only when the fabric is actually worn through. However, in actual use, when the nap height is less than half of the fabric's height, it significantly impacts the roller brush's performance, rendering it ineffective.

[0003] In related technologies, abrasion resistance tests are often conducted on the fabric of the roller brush before its production. Testing methods include flexural abrasion and flat abrasion, and instruments for these methods are available on the market. However, these methods and instruments primarily focus on testing the fabric's abrasion resistance. While they provide some reference for the roller brush's durability or abrasion resistance, they are unsuitable for testing the durability or abrasion resistance of the fabric on a pre-made roller brush.

[0028] This application relates to a roller brush testing device, which includes a sample stage 1000, a clamping assembly 2000, and a driving assembly 3000. The sample stage 1000 is used to place sandpaper, the clamping assembly 2000 is used to clamp and fix the handle of the roller brush, and the driving assembly 3000 is used to drive the clamping assembly 2000 to reciprocate along a set first direction.

[0029] Before testing, the user prepares the roller brush by removing loose hairs with transparent tape and measuring the initial hair height. Different types of sandpaper are also selected based on the material of the roller brush.

[0030] Understandably, the roller brush testing device includes a base 4000, a sample stage 1000 disposed on the base 4000, and a drive assembly 3000 disposed on the base 4000. Specifically, the sample stage 1000 is located on the upper side of the base 4000, and under the drive of the drive assembly 3000, the clamping assembly 2000 drives the roller brush to reciprocate on the sandpaper on the sample stage 1000.

[0031] It should be noted that the roller brush testing device includes a counterweight structure 5000, which is disposed on the clamping assembly 2000 to increase the stability of the clamping assembly 2000 and the roller brush, and to set the pressure parameters during the roller brush test through the counterweight structure 5000.

[0032] In some embodiments, the clamping assembly 2000 includes a first clamping seat 2101 and a second clamping seat 2102, and the handle of the roller brush can be clamped between the first clamping seat 2101 and the second clamping seat 2102. The first clamping seat 2101 is disposed on the upper side of the second clamping seat 2102, and the first clamping seat 2101 and the second clamping seat 2102 are detachably connected. The drive assembly 3000 is connected to the second clamping seat 2102.

[0033] Furthermore, the counterweight structure 5000 is disposed on the first clamping base 2101, and the counterweight structure 5000 is located on the upper side of the first clamping base 2101. Specifically, the first clamping base 2101 is provided with a first column for mounting the counterweight structure 5000, the first column is located on the upper side of the first clamping base 2101, and the counterweight structure 5000 has a through hole so that the seeding structure can be sleeved on the first column.

[0034] Regarding the manner in which the counterweight structure 5000 is disposed on the clamping assembly 2000, at least the following alternative embodiments exist.

[0035] In some alternative embodiments, the counterweight structure 5000 is disposed on the second clamping base 2102, and the counterweight structure 5000 is located on the upper side of the second clamping base 2102. Further, the second clamping base 2102 is provided with a second column for mounting the counterweight structure 5000, and the second column is located on the upper side of the second clamping base 2102.

[0036] In some implementations, the counterweight structure 5000 includes weights of standard weight, which helps to accurately control the test parameters.

[0037] Furthermore, the counterweight structure 5000 includes at least two weights of different weights, allowing the user to change the pressure parameters of the roller brush test by replacing the weights of different weights and several combinations of weights.

[0038] In some embodiments, the clamping assembly 2000 includes a clamping locking assembly for securing the handle of the roller brush. The clamping locking assembly is connected to a first clamping base and a second clamping base respectively, thereby clamping and securing the handle of the roller brush.

[0039] Specifically, the clamping and locking assembly includes a clamping pressure plate 2201, a clamping locking member 2202, and a third column. The third column is disposed on the upper side of the second clamping base, and the two ends of the third column are respectively connected to the first clamping base and the second clamping base. The clamping locking member 2202 is disposed on the first clamping base, and the clamping pressure plate 2201 is located between the first clamping base and the second clamping base. The clamping locking member 2202 is connected to the clamping pressure plate 2201, and the clamping pressure plate 2201 is sleeved on the outer side of the third column.

[0040] It should be noted that the user places the handle of the roller brush between the clamping plate 2201 and the second clamping base, and the user uses the clamping locking member 2202 to press the clamping plate 2201 to press the handle of the roller brush, thereby completing the clamping and fixing.

[0041] In some examples, the clamping locking element 2202 is threadedly connected to the first clamping base. Specifically, the clamping locking element 2202 is provided with external threads, the first clamping base is provided with threaded through holes, and one end of the clamping locking element 2202 is rotatably connected to the clamping pressure plate 2201.

[0042] It is understandable that when the user rotates the clamping locking member 2202, the clamping locking member 2202 moves linearly with the first clamping base via a helical transmission. This causes the clamping locking member 2202 to move the clamping pressure plate 2201, so that the clamping pressure plate 2201 presses against the handle of the fixed roller brush. The third column also serves as a guide for the movement of the clamping pressure plate 2201.

[0043] In some examples, the clamping locking element 2202 is set as a screw, bolt, or stud.

[0044] In some examples, the clamping and locking assembly includes a clamping elastic element 2203, which is configured as a compression spring. The clamping elastic element 2203 is sleeved on the third column, and one end of the clamping elastic element 2203 abuts against the clamping pressure plate 2201.

[0045] Furthermore, when the clamping plate 2201 presses against the handle of the roller brush, the clamping elastic element 2203 generates compressive elastic potential energy. Therefore, when the user rotates the clamping locking element 2202 to remove the handle of the roller brush, the clamping elastic element 2203 can generate an elastic thrust on the clamping plate 2201, so that the clamping plate 2201 moves away from the handle of the roller brush, making it easier and less strenuous for the user to operate.

[0046] In some examples, the clamping and locking assembly provides two third posts for the clamping plate 2201 to improve the stability of the movement of the clamping plate 2201.

[0047] In some examples, the clamping pressure plate 2201 in the clamping and locking assembly is set to two, and each clamping pressure plate 2201 is equipped with a clamping locking element 2202.

[0048] In some embodiments, the clamping assembly 2000 includes a clamping stop 2300 for abutting the end of the handle of the roller brush to position the handle of the roller brush in the clamping assembly 2000.

[0049] Specifically, the clamping limiting member 2300 is disposed on the upper side of the second clamping base. Further, the clamping limiting member 2300 is configured as a limiting seat or a limiting plate.

[0050] In some embodiments, the drive assembly 3000 is connected to the clamping assembly 2000 via a movable base 3100. Specifically, the drive assembly 3000 is connected to the movable base 3100, and the movable base 3100 is connected to the second clamping base. It is understood that the drive assembly 3000 drives the movable base 3100 to reciprocate along a first direction, and the movable base 3100 in turn drives the clamping assembly 2000 to reciprocate along the first direction.

[0051] To ensure smooth movement of the movable seat 3100, the roller brush testing device includes a guide assembly 6000, which is disposed on the base 4000. The guide assembly 6000 includes a guide structure extending along a first direction, and the movable seat 3100 is movably disposed on the guide structure. It is understood that the movable seat 3100 reciprocates along the guide structure in the first direction.

[0052] In some examples, the guide assembly 6000 includes guide side plates 6100 spaced apart along a second direction perpendicular to the first direction, the guide side plates 6100 extending along the first direction, and the guide structure being configured as a groove 6101 on the guide side plates 6100. A movable seat 3100 is located between the two guide side plates 6100, and the movable seat 3100 has a sliding portion disposed in the groove 6101.

[0053] Furthermore, the guide assembly 6000 includes a guide base 6200 and a guide side plate 6100 erected on the guide base 6200. In some examples, the guide base 6200 and the guide side plate 6100 can also be designed as an integral part, with the two sides of the guide base 6200 bent to form the guide side plate 6100.

[0054] Regarding the guide structure, at least the following alternative embodiments exist.

[0055] In some alternative embodiments, the guide structure is configured as a guide rail.

[0056] In some alternative embodiments, the guide structure is configured as a guide rod.

[0057] In some alternative embodiments, the guide structure is configured as a guide slot on the upper side of the base 4000.

[0058] In some embodiments, the roller brush testing device includes a limiting component 7000 disposed on the base 4000. Specifically, the limiting component 7000 is located on the upper surface of the base 4000, and the limiting component 7000 is used to further limit the movement direction of the clamping component 2000 to a first direction.

[0059] Specifically, the limiting component 7000 includes limiting edge structures 7100 arranged at intervals along a second direction perpendicular to the first direction. The limiting edge structures 7100 are arranged in pairs, and the two pairs of limiting edge structures 7100 are arranged at intervals along the second direction. The two pairs of limiting edge structures 7100 are located on both sides of the limiting component 7000.

[0060] Furthermore, the second clamping seat 2102 is located between the two limiting edge structures 7100 on both sides, and the two limiting edge structures 7100 on both sides limit the movement direction of the second clamping seat 2102 to the first direction.

[0061] In some examples, the limiting component 7000 includes a limiting base 7200, a limiting stop structure 7100 disposed on the limiting base 7200, and the limiting base 7200 disposed on the base 4000.

[0062] In some examples, the limiting edge structure 7100 is set as a limiting column.

[0063] In some embodiments, the drive assembly 3000 includes a crank-rocker mechanism connected to the movable seat 3100.

[0064] Specifically, the rocker arm in the crank-rocker mechanism is hinged to the movable seat 3100, and the crank-rocker mechanism and the movable seat 3100 constitute a crank-rocker-slider mechanism.

[0065] Understandably, the drive assembly 3000 includes a drive motor, and the crank of the crank-rocker mechanism is fixedly connected to the shaft of the drive motor.

[0066] In some examples, the brush test apparatus includes a housing 4100 disposed on the upper side of the base 4000, and a drive motor disposed inside the housing 4100.

[0067] It should be noted that, regarding the structure of the drive assembly 3000, at least the following alternatives exist: the drive assembly 3000 includes a cylinder or hydraulic rod or a gear and rack mechanism or a lead screw mechanism or a belt drive mechanism.

[0068] In some embodiments, the roller brush testing device includes a sensor 4200 disposed on the side wall of the housing 4100, which is used to monitor the number of crank rotations in the crank-rocker mechanism. It is understood that the sensor 4200 is triggered once for each crank rotation.

[0069] Furthermore, the roller brush testing device includes a circuit board, with a sensor 4200 electrically connected to the circuit board, which has a processing chip. The sensor 4200 triggers a signal and transmits it to the circuit board, which then performs counting.
