DETAILED DESCRIPTION

[0016] exist Figure 1 , Figure 2 , Figure 3In the present invention, a driving disk 1 and a driven sheave 2 are provided. A cylindrical pin is fixed on the upper disk surface of the driving disk 1. The driving disk 1 can rotate around its own central axis. The driven sheave 2 is processed with 4 evenly distributed radial grooves 2-2. Two adjacent radial grooves 2-2 in a plane form an angle of 90 degrees. The two adjacent radial grooves 2-2 are connected by an arc surface. A square groove is processed on the upper side surface of the driven sheave 2. The cylindrical pin enters the radial groove 2-2 and drives the driven sheave 2 to rotate and stop periodically around its own central axis. The driven sheave 2 is provided with 4 evenly distributed thickness measuring holes 2-1. A set of laser distance measuring sensors 3 are respectively provided at the axis center positions of the driven sheave 2 and the thickness measuring holes 2-1. A weighing arm 4 is horizontally provided above the driven sheave 2. A pressure sensor is provided in the weighing arm 4. The weighing arm 4 includes an electromagnetic rod 4-1 and a measuring rod 4-3. The electromagnetic rod 4-1 and the measuring rod 4-3 are connected by a connecting rod 4-2. A pressure sensor is arranged inside the connecting rod 4-2. A photoelectric sensor transmitting end 4-4 is installed on the measuring rod 4-3, and a photoelectric sensor receiving end 4-5 is installed on the electromagnetic rod 4-1. An electromagnetic coil 4-6 is vertically installed at one end of the electromagnetic rod 4-1. The electromagnetic coil 4-6 is electrically connected to a control unit. The control unit controls the on and off of the current of the electromagnetic coil 4-6. The other end of the weighing arm 4 is hinged with a weighing arm power assembly 5. The weighing arm power assembly 5 drives the weighing arm 4 to move in a plane around the hinge axis. The weighing arm power assembly 5 is a cylinder device. The telescopic rod of the cylinder is hinged with the end of the weighing arm 4 through a pin shaft. The weighing arm power assembly 5 drives the weighing arm 4 to move in a plane.

[0017] When the cylindrical pin on the driving disk 1 enters the radial groove 2-2, it drives the driven groove wheel 2 to rotate. When the cylindrical pin leaves the radial groove 2-2, the driven groove wheel 2 stops moving until the next time the cylindrical pin enters another radial groove. In this way, the driven groove wheel 2 performs intermittent rotational motion.

[0018] The cut square steel cord fabric sample is placed in the square groove of the driven groove wheel 2. A thickness measuring hole 2-1 is provided at each corner of the square groove. The laser ranging sensor 3 at the center of the thickness measuring hole 2-1 axis detects the thickness of the four corners of the square sample. The laser ranging sensor 3 at the center of the driven groove wheel 2 axis detects the thickness of the center of the square sample.

[0019] The on and off of the current of the electromagnetic coil 4-6 on the electromagnetic rod 4-1 is controlled by the photoelectric sensor. When the electromagnetic coil 4-6 is energized, the electromagnetic rod 4-1 becomes magnetic and the sample is attracted to the electromagnetic rod 4-1 by the magnetic force, thereby affecting the change of the pressure sensor of the connecting rod 4-2. The quality is then analyzed by the data module.

[0020] The above are only preferred specific implementations of this embodiment, but the protection scope of this embodiment is not limited to this. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and inventive concept of this embodiment within the technical scope disclosed in this embodiment, which should be covered by the protection scope of this embodiment.
