Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0035]It can be seen from the accompanying drawings that the present invention is a test device for the friction coefficient between the working surface of the tape and the roller, which includes a driving roller, two reversing rollers and a force measuring device, and is characterized in that the device includes two sets of force measuring device, the tape goes around a set of vertical force measuring devices from right to left, then goes around the reversing roller forward, then returns to go around a driving roller and a reversing roller, turns back and becomes the tape at the bottom, and then The adhesive tape at the bottom goes around a group of vertical measuring devices from left to right.
[0036] Further, the adhesive tape goes around a set of vertical force measuring devices from right to left, which is composed of three supporting rollers. Th...

The invention relates to an adhesive tape work surface and drum friction coefficient testing apparatus, which comprises a drive drum, two reversing drums, and force measurement devices, and is characterized in that the apparatus comprising two groups of the force measurement devices, an upper adhesive tape bypasses one group of the sequentially established force measurement devices from right to left, then forward bypasses the reversing drum, returns, then bypasses a drive drum and a reversing drum, and turns back to form a lower adhesive tape, and the lower adhesive tape bypasses one group of the sequentially established force measurement devices from left to right. According to the present invention, the tight edge and the loose edge of the adhesive tape bypassing the drive drum are respectively provided with one group of the force measurement device comprising three supporting rollers, the tension force values of the tight edge and the loose edge of the adhesive tape are obtained through the tension force sensor and the secondary instrument arranged on the force measurement device left, and after the parameter data is determined, the friction coefficient [mu] between adhesive tape work surface and the drum can be calculated through the derived formula; and the method is simple and practical.
Description
technical field [0001] The present invention relates to a test device for conveying machinery, in particular to a test device and test method for the friction coefficient between the belt working surface and the roller of a belt conveyor, which is a kind of friction coefficient between the belt working surface and the roller when the belt conveyor is running. A special device for testing coefficients. Background technique [0002] To study the optimal design of the belt conveyor, it is necessary to test various technical parameters of the belt conveyor. By testing the relevant parameters of belt conveyors of different models and different structures, a database is formed, which is summarized, analyzed and processed, and then used in turn to optimize the design of belt conveyors. The technical data we use to design the belt conveyor is partly borrowed from some foreign technical data, and our country has its own equipment characteristics and technical characteristics, so it ...
