DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-7, the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0026] According to one embodiment of the utility model, Figure 1-Figure 7 As shown: This embodiment provides a cloth wear resistance testing machine, including a workbench 101, support frames 102 are symmetrically arranged on both sides of the workbench 101, and a tensioning and fixing assembly 200 is arranged under the support frame 102;

[0027] The tensioning and fixing assembly 200 includes a plurality of telescopic push rods 201 arranged on the support frame 102, a pressure block 202 is arranged at the end of the telescopic push rod 201, a groove is provided on the pressure block 202, a roller 203 is provided in the groove, fixed rollers 204 are arranged on both sides of the roller 203, a notch is provided at the end of the fixed roller 204 at a position corresponding to the inner wall of the groove, a bearing 205 is sleeved on the fixed roller 204, a fixed block 206 is fixedly provided on the bearing 205, a strong spring 207 is provided between the top of the groove and the fixed block 206, a driving motor 208 is provided on the outer wall of one side of the pressure block 202, a rotating shaft 209 is provided on the output shaft of the driving motor 208, and the rotating shaft 209 passes through the outer wall of the pressure block 202 and is connected with the fixed roller 204;

[0028] When conducting a wear test on fabrics, the staff first needs to lay the fabric to be tested flat on the inspection table 105, and then start the drive motor 208 and the electric telescopic push rod 201. The electric telescopic push rod 201 extends to drive the pressing block 202 to move downward. When the pressing block 202 moves downward, the roller 203 contacts the fabric to be tested, and the rotating shaft 209 of the drive motor 208 rotates. When the rotating shaft 209 rotates, it drives the fixed roller 204 to rotate. The fixed roller 204 rotates and drives the roller 203 to rotate. The fixed roller 204 is provided with a bearing 205. The bearing 205 can ensure that the fixed roller 204 does not affect the fixed roller when it rotates. The block 206 moves up and down, and the roller 203 rotates toward the outside of the inspection table 105, so that the roller 203 rotates to tighten the fabric. A rubber sleeve is provided on the roller 203, and the rubber sleeve can increase the friction force when the roller 203 rotates, so that the roller 203 can better tighten the fabric. While the fabric is tightened, the pressing block 202 continues to move downward. The roller 203 is forced to shrink into the groove, driving the fixed block 206 to move upward. When the fixed block 206 moves upward, the dovetail sliders on both sides of the fixed block 206 move along the dovetail slide groove. The use of the dovetail slider and the dovetail slide groove can limit the position of the fixed block 206. To prevent the fixed block 206 from tilting during movement and affecting the tightening and fixing effect, the fixed block 206 drives the strong spring 207 to continuously contract when moving backward until the bottom of the pressure block 202 is completely in contact with the cloth, the roller 203 stops rotating, and the cloth is tightened and fixed. The strong spring 207 is provided with notches at the head and tail, and the head and tail of the strong spring 207 are fixed in the notches. The notches can fix the position of the strong spring 207 to prevent the strong spring 207 from bending and flying out under force. Then, the friction component 104 can be started to test the wear resistance of the cloth. After the test is completed, the electric telescopic push rod 201 contracts backward to drive the pressure block 202 rises, the spring in the pressing block 202 expands to drive the fixing block 206 to move downward, and the roller 203 pops out from the groove. Then the staff detects the wear resistance of the cloth, and the qualified cloth is collected by the staff, and the unqualified cloth is directly grabbed by the manipulator in the crushing mechanism 103 and sent to the crushing mechanism 103 for processing; the use of machinery instead of manual fixation of the cloth to be tested reduces the steps that require manual participation when using the cloth wear resistance testing machine, which not only ensures the safety of the staff, but also can better tighten the position of the fixed cloth, improve the accuracy of cloth wear resistance detection, and improve the efficiency of cloth detection.

[0029] The use of this utility model:

[0030] When conducting a wear test on fabrics, the staff first needs to lay the fabric to be tested flat on the inspection table 105, and then start the drive motor 208 and the electric telescopic push rod 201. The motor in the electric telescopic push rod 201 uses a worm gear to drive a pair of lead screw nuts to move along the worm gear. The lead screw nuts change the rotational motion of the motor into a linear motion, and the rotation of the motor drives the electric telescopic push rod 201 to extend. The extension of the electric telescopic push rod 201 drives the pressing block 202 to move downward. When the pressing block 202 moves downward, the roller 203 and the fabric to be tested are in contact. The control unit of the drive motor 208 converts the high-voltage direct current into alternating current, and then supplies the power supply to the motor through the three-phase power input terminals on the drive motor 208. When alternating current is input into each input terminal of the three-phase power, a rotating magnetic field is generated in the stator, and an induced current is generated in the rotor. Under the action of the magnetic field force, the rotating shaft 209 of the drive motor 208 starts to rotate. When the rotating shaft 209 rotates, it drives the fixed roller 204 to rotate. When the fixed roller 204 rotates, it drives the roller 203 to rotate. The direction of rotation of the roller 203 is toward the outside of the inspection table 105, and the roller 203 rotates. The rotation of the drum 203 can tighten the fabric. While tightening, the pressing block 202 continues to move downward, and the drum 203 is forced to shrink, driving the fixed block 206 to move upward. When the fixed block 206 moves upward, it drives the spring to shrink continuously until the bottom of the pressing block 202 is completely in contact with the fabric. The drum 203 stops rotating, and the fabric is tightened and fixed. Then, the friction component 104 can be started to test the wear resistance of the fabric. After the test is completed, the electric telescopic push rod 201 shrinks backward to drive the pressing block 202 to rise, and the spring in the pressing block 202 expands to drive the fixed block 206 moves downward, and the roller 203 pops out of the groove. Then the staff tests the wear resistance of the cloth. The qualified cloth is collected by the staff, and the unqualified cloth is directly grabbed by the manipulator in the crushing mechanism 103 and sent to the crushing mechanism 103 for processing; the use of machinery instead of manual fixation of the cloth to be tested reduces the steps that require manual participation when using the cloth wear resistance testing machine, which not only ensures the safety of the staff, but also can better tighten and fix the position of the cloth, improve the accuracy of cloth wear resistance detection, and improve the efficiency of cloth detection.

[0031] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
