Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to the design of a floor brush roller speed testing device. Background Technology

[0002] Vacuum cleaners are an essential cleaning tool in our daily lives, and one of the most important components is the vacuum cleaner roller brush. The vacuum cleaner roller brush is one of the core components of a vacuum cleaner. Its function is to use the rotating brush to suck up dust, hair, and other debris from the floor, thereby cleaning the floor.

[0003] To ensure the quality of vacuum cleaners, the roller brush of the vacuum cleaner must be tested for speed after production. The existing method for measuring the speed of the vacuum cleaner roller brush is to use an infrared sensor to measure the speed of the roller brush after the vacuum cleaner is started. This method is not accurate and is prone to large errors.

[0004] Our company's earlier application for a vacuum cleaner roller brush speed measuring machine has solved the above problems. However, this vacuum cleaner roller brush speed measuring machine can only clamp the floor brush head of a set length and measure the speed of the roller brush of a set length. If the speed of roller brushes of different lengths is to be measured, it needs to be redesigned. It is not very flexible in use and cannot meet the production needs of enterprises.

[0005] To address the aforementioned problems, this utility model discloses a device for testing the speed of a floor brush roller. Utility Model Content

When the brush head is clamped between two L-shaped clamps, the speed encoder can be adjusted to the corresponding position so that the gear on its output shaft meshes with the gear on the brush head roller.

[0011] More preferably, the bidirectional drive unit is one of a bidirectional servo screw module or a bidirectional cylinder.

[0013] A further preferred embodiment is that the two L-shaped clamps have a rubber pad attached to their opposite sides.

[0014] More preferably, it also includes a slider, the slider having a transversely opened shaft hole into which the optical rod is inserted, and an adjusting bolt that can abut or disengage from the optical rod is screwed onto the longitudinal side of the slider, and the speed encoder is mounted on the slider.

[0015] More preferably, the testing machine has a clearance groove communicating with the groove, and the light rod corresponds to the clearance groove.

[0035] Example

[0036] To address the shortcomings of existing technologies for testing the speed of floor brush rollers, such as their inability to test rollers of different lengths, lack of flexibility, and inability to meet the production needs of enterprises, this paper refers to... Figures 1-3 As shown, this application discloses a floor brush roller speed testing device, comprising:

[0037] The testing machine 10 has a groove 11 on its upper part;

[0038] The floor brush head clamping mechanism 20 includes a bidirectional drive unit 21 arranged laterally inside the groove 11 and an L-shaped clamping plate 22 connected to the two drive parts of the bidirectional drive unit 21.

[0039] The speed detection mechanism 30 includes a light rod 40 disposed on one longitudinal side of the groove 11, a speed encoder 31 slidably fixed on the light rod 40, and a gear 32 mounted on the output shaft of the speed encoder 31. When the ground brush head is clamped between two L-shaped clamps 22, the speed encoder 31 can be adjusted to the corresponding position so that the gear 32 on its output shaft meshes with the gear 32 on the roller brush of the ground brush head.

[0040] In actual use, the operator places the floor brush head to be tested between two L-shaped clamps 22, and then controls the bidirectional drive unit 21 to drive the two L-shaped clamps 22 to move towards each other until the floor brush head is clamped. After that, the operator adjusts the position of the speed encoder 31 so that its gear 32 meshes with the brush roller gear 32 inside the floor brush head. Finally, the floor brush head is started to work, and the speed of the brush roller is detected in real time by the speed encoder 31.

[0041] Optionally, the bidirectional drive unit 21 of this application can be either a bidirectional servo screw module or a bidirectional cylinder. Under the drive of the bidirectional servo screw module or the bidirectional cylinder, the two L-shaped clamps 22 can move towards each other or away from each other, thereby realizing the loosening and loosening of the ground brush head.

[0042] In order to enable the two L-shaped clamps 22 to move stably toward or away from each other, this application provides steps 13 on both sides of the longitudinal direction of the groove 11. A linear guide rail 23 is arranged above one of the steps 13 in the transverse direction, and a bidirectional drive unit 21 is arranged in the transverse direction on the other step 13. The two L-shaped clamps 22 are respectively connected to the linear guide rail 23 and the bidirectional drive unit 21. Under the bidirectional drive unit 21, the two L-shaped clamps 22 can move away from or toward each other.

[0043] In another preferred embodiment, the present application also attaches a rubber pad 221 to the two L-shaped clamps 22 on their opposite sides. Since the rubber pad 221 can protect the floor brush head, the floor brush head can be protected from damage.

[0044] In order to adjust the position of the speed encoder 31, this application also includes a slider 50. The slider 50 has a horizontal shaft hole inside which the light rod 40 is inserted. An adjusting bolt 60 is screwed onto the longitudinal side of the slider 50, which can abut or disengage from the light rod 40. The speed encoder 31 is mounted on the slider 50. In specific implementation, the operator can screw the adjusting bolt 60 to disengage from the light rod 40. At this time, the position of the speed encoder 31 can be changed by moving the slider 50. After adjusting the position of the speed encoder 31 and making the gear 32 on the speed encoder 31 mesh with the gear 32 on the brush roller, the operator can screw the adjusting bolt 60 to fix it to the light rod 40.

[0045] In addition, in order to enable operators to adjust the slider 50, this application provides a clearance groove 12 that communicates with the groove 11 on the testing machine. The light rod 40 corresponds to the clearance groove 12. In actual use, the operator can observe the position of the speed encoder 31 on the slider 50 and the position of the gear 32 on the brush roller through the clearance groove 12. Based on the information obtained from the observation, the operator can manually adjust the slider 50 so that the gear 32 on the speed encoder 31 meshes with the gear 32 on the brush roller.

[0046] In addition to the above structure, this application also provides a controller 70, a display panel 80 and an alarm 90 on the test machine 10. The speed encoder 31 is connected to the output terminal of the controller 70, and the display panel 80 and the alarm 90 are connected to the output terminal of the controller 70. When the speed encoder 31 measures the speed, the speed information it detects will be sent to the controller 70 in real time and displayed on the display panel 80. If the final measured speed is unqualified, the controller 70 will control the alarm 90 to sound an alarm.
