Technical Field

[0001] The invention belongs to the technical field of a carpet tension control device for energy efficiency testing of a vacuum cleaner. Background Art

[0002] The EU market has implemented mandatory control over the energy performance and dust removal performance (carpet and hard floor) of household vacuum cleaners since September 1, 2014. According to the EU Energy Efficiency Framework Directive 2009 / 125 / EC, vacuum cleaners that do not meet the eco-design requirements will not be allowed to be put on the EU market. More than half of the world's household vacuum cleaners are produced in mainland China, and more than 80% of domestic manufacturers are concentrated in Suzhou, Jiangsu Province. As a well-known third-party testing agency, it is our responsibility to provide accurate testing services to help customers improve product performance and seize European market share.

[0003] In order to provide this testing service, it is necessary to build a laboratory according to the requirements of IEC / EN60312-1 and customize the dust removal performance test equipment. In this equipment, how to ensure the accuracy of the tension on the carpet and the test data, so we specially develop its implementation and control device. The existing test device that uses weights to provide tension has the defect of force transmission loss. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the existing weight control tension and provide a carpet tension test device which is easy to operate and has higher accuracy.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] A carpet tension control device comprises a profile frame, a table top, a carpet tension fixing hanger and a carpet tension regulating assembly, wherein the carpet tension regulating assembly comprises a fixed part and a moving part, wherein the table top and the fixed part of the carpet tension regulating assembly are respectively fixed on different dimensions of the profile frame, and the moving part of the carpet tension fixing hanger is connected to the carpet tension fixing hanger and guides the movement of the carpet tension fixing hanger.

[0007] Furthermore, the table top is arranged above the carpet tensioning and regulating component, that is, the moving part of the carpet tensioning and regulating component moves below the table top.

[0008] Furthermore, the carpet tensioning and fixing hanger is two cylindrical rods. When in use, the two round holes on the carpet are sleeved on the two cylindrical rods and then laid flat on the table.

[0009] Furthermore, the fixed part of the carpet tensioning and regulating component includes a transverse fixing plate and a longitudinal fixing plate, the transverse fixing plate is arranged on the profile frame, and the longitudinal fixing plate is arranged on the transverse fixing plate; the moving part of the carpet tensioning and regulating component includes a free arm, a rotating bearing, a force sensor, a connecting piece and a pen-shaped cylinder, the two ends of the free arm are respectively connected to the carpet tensioning and fixing hanger, the free arm, the rotating bearing, the force sensor, the connecting piece and the pen-shaped cylinder are connected in sequence, and the pen-shaped cylinder is arranged on the longitudinal fixing plate.

[0010] The carpet tension testing device of the present invention is that when a carpet is laid flat on a wooden table, its round hole is sleeved on the carpet tensioning rod, the pen-shaped cylinder is pushed forward, and the free arm moves forward, thereby tightening the two ends of the carpet until a preset tensioning force is reached. Through the force sensor, the instantaneous value of the tensioning force is directly read on the display and saved in the computer.

[0011] Beneficial effects of the present invention:

[0012] The carpet tension testing device of the present invention provides tensioning force through a cylinder, and a sensor and a terminal display provide real-time monitoring. The tension testing device has the characteristics of no transmission loss, easy operation, monitoring and data storage.

[0013] At the same time, the improvement of the carpet tension control system can avoid repeated testing and improve the accuracy and credibility of vacuum cleaner energy efficiency test data. BRIEF DESCRIPTION OF THE DRAWINGS
