[0003] In the process of quality inspection of carpets, it is usually necessary to conduct various performance tests on carpets. When conducting wear resistance test on carpets, if the carpet contains fiber debris, the fiber debris will constantly rub the tufts, aggravating the wear of the tufts. Therefore, the tuft wear degree of the carpet with fiber debris is greater than that of the carpet without fiber debris, which makes the difference in tuft wear between the two too large, resulting in a large numerical deviation of wear resistance of another different carpet in the wear resistance test, making the wear resistance test of the carpet unconvincing.

[0035] The following is the working content of the present invention: First, the staff fixes the carpet 3 in the drawer 2 with the tufted side facing up through the fixing clip on the drawer 2, and then inserts the drawer 2 into the detection box 1. The following figure is used as the perspective reference for orientation description. The side where the squeezing roller 104 is located is the left side. Then, the first electric slider 102 is controlled to move rightward along the first slide rail 101 to the lower side of the carpet 3, thereby driving the first driving member 103 and the squeezing roller 104 to move to the lower side of the carpet 3, and then the first driving member 103 is controlled to move the squeezing roller 104 upward, so that the squeezing roller 104 squeezes the carpet 3, so that the carpet 3 is deformed under the squeezing of the squeezing roller 104, so that the part of the carpet 3 squeezed by the squeezing roller 104 changes from horizontal to arched, so that the tufts at the above-mentioned deformed part of the carpet 3 are expanded, so that the upper ends of the tufts are separated from each other, exposing the connection between the tufts and the backing on the carpet 3, and then exposing the fiber debris adhered to the above-mentioned connection.

[0036] Subsequently, the second electric slider 202 is controlled to slide rightward along the second slide rail 201, thereby driving the second driving member 203, the connecting frame 204 and the fixing frame 208 to move rightward, and then driving the electrostatic brush 4, the scraper 5 and the motor 209 to move rightward. Subsequently, the second driving member 203 is controlled to make the connecting frame 204, the fixing frame 208, the electrostatic brush 4 and the scraper 5 move downward. The electrostatic brush 4 and the scraper 5 located on the right side of the second driving member 203 are used for explanation. When the electrostatic brush 4 and the scraper 5 are in contact with the connection between the tufts and the backing on the carpet 3, the second driving member 203 stops, so that the electrostatic brush 4 and the scraper 5 stop moving downward, so that the electrostatic brush 4 and the scraper 5 and the arched part of the carpet 3 are as shown in the figure. Figure 6 At the same time, the third electric slider 301 on the right side is controlled to move leftward along the second slide rail 201, thereby driving the connecting plate 302 and the collecting box 303 on the right side to move leftward to the position shown in FIG. Figure 6Then, after the above-mentioned operation preparation is completed, the squeezing roller 104 is driven to continue to move rightward by the first electric slider 102, so that the squeezing roller 104 squeezes the rest of the carpet 3, causing the rest of the carpet 3 to deform and become an arch. Subsequently, the staff observes whether the carpet 3 recovers to its original state after deformation, thereby realizing the overall flexibility test of the carpet 3, and then realizing the quality test of the carpet 3. At the same time, when the first electric slider 102 continues to drive the squeezing roller 104 to move rightward, the second electric slider 202 is synchronously controlled to drive the electrostatic brush 4 and the scraper 5 to move rightward, and the third electric slider 301 located on the right side is controlled to drive the third electric slider 301 located on the right side. The connecting plate 302 and the collecting box 303 move to the right. It is worth noting that the moving speeds of the first electric slider 102, the second electric slider 202 and the third electric slider 301 are the same. At the same time, based on the view from the front to the back, the control motor 209 drives the electrostatic brush 4 and the scraper 5 to rotate counterclockwise, so that the electrostatic brush 4 and the scraper 5 scratch the connection between the tuft and the backing during the rotation, so that the fiber debris adhered to the above connection falls off from the above connection under the scratching of the electrostatic brush 4 and the scraper 5. Subsequently, the fiber debris falling off from the above connection and the fluff falling off from the tuft will be thrown to the right to the position of the collecting box 303 under the rotation of the electrostatic brush 4 and the scraper 5. At this time, the air pump is controlled to generate suction on the collection box 303 through the connecting plate 302, so that the above-mentioned fiber debris and fluff fall into the collection box 303 under the action of the suction force, so that the flying fiber debris and fluff are collected by the collection box 303, and the fiber debris and fluff are prevented from falling back on the remaining tufts, polluting the remaining tufts, and affecting the subsequent wear resistance test of the remaining tufts. In the above process, the fiber debris adhering to the above-mentioned connection is cleaned by the rotating electrostatic brush 4 and the scraper 5, so as to avoid the situation in which some carpets 3 are adhered to fiber debris and some carpets 3 are not adhered to fiber debris during the subsequent wear resistance test of another identical carpet 3. The fiber debris will continuously rub the tufts during the subsequent wear resistance test of the carpet 3, aggravating the wear of the tufts. As a result, in the subsequent wear resistance test of the carpet 3, the tufts of the carpet 3 with the fiber debris attached are more worn than those of the carpet 3 without the fiber debris attached, resulting in a large difference in tuft wear between the two. This leads to a large numerical deviation of the wear resistance of the same carpet 3 in the wear resistance test, making the wear resistance test of the carpet 3 unconvincing and unconvincing. Compared with the prior art, the interference of the fiber debris on the wear resistance test of the carpet 3 is avoided, and the credibility of the carpet 3 in the wear resistance test is improved.

[0037] At the same time, when the electrostatic brush 4 and the scraper 5 are rotating to clean the fiber debris at the connection between the tuft and the backing, since the diameter of the semicircular hole 5001 on the scraper 5 is smaller than the diameter of the tuft, and the tuft itself is soft and deformable, the tuft will be embedded in the semicircular hole 5001 on the scraper 5 under the squeezing of the semicircular hole 5001 on the scraper 5, so that the scraper 5 drives the tuft to move upward through the semicircular hole 5001 under rotation, and then applies an upward force to the tuft embedded in the semicircular hole 5001, so that the tuft embedded in the semicircular hole 5001 tends to move upward, thereby tightening the space between the tuft and the backing. 5001, and is thrown into the collecting box 303 under the rotation of the scraper 5. Since the front side of the detection box 1 is set to be made of glass, the staff can observe the amount of fluff in the collecting box 303 through the detection box 1 to determine whether the quality of the carpet 3 is qualified. If there is a lot of fluff in the collecting box 303, the quality of the carpet 3 has problems, and the carpet 3 is directly replaced and the above-mentioned test is performed.

[0038] Subsequently, after the squeezing roller 104 moves rightward to the right edge of the carpet 3, the first driving member 103 is controlled to stop driving the squeezing roller 104 to move, and at the same time, the second electric slider 202 is controlled to drive the electrostatic brush 4 and the scraper 5 to continue to move rightward, so that the electrostatic brush 4 and the scraper 5 on the left side are in contact with the connection between the tufts and the backing, and the third electric slider 301 on the right side is controlled to stop moving, so that the collecting box 303 on the right side stops moving, and then the third electric slider 301 on the left side is controlled to drive the connecting plate 302 and the collecting box 303 to move rightward, and when the collecting box 303 moves to the left side of the arched part of the carpet 3 Stop the third electric slider 301 from moving to the right, then control the first electric slider 102 to drive the squeezing roller 104 to move to the left, and control the second electric slider 202 to drive the electrostatic brush 4 and the scraper 5 to move to the left. At the same time, control the third electric slider 301 on the left to drive the connecting plate 302 and the collecting box 303 to move to the left, so that the flexibility of the carpet 3 is tested again through the movement of the squeezing roller 104 from right to left. At the same time, the connection degree of the tufting and the backing is tested again through the semicircular hole 5001 on the scraper 5. Repeat the above operation to achieve multiple tests on the carpet 3 and improve the credibility of the test data.

[0039] Subsequently, after the flexibility test of the carpet 3 is completed, the first driving member 103 is controlled to drive the squeezing roller 104 to move downward to the initial position, and the third electric slider 301 is controlled to drive the connecting plate 302 and the collecting box 303 to move to the initial position. Figure 2The second electric slider 202 is controlled to drive the second driving member 203, the connecting frame 204, the electrostatic brush 4 and the scraper 5 to move to the position shown in FIG. Figure 2 The electrostatic brush 4, the scraper 5, the squeezing roller 104 and the collecting box 303 are reset, and then the second driving member 203 is controlled to make the connecting frame 204, the servo motor 205, the rotating shaft 206 and the pressing plate 207 move downward, so that the pressing plate 207 squeezes the tufts on the carpet 3. Subsequently, the second driving member 203 is controlled to stop the pressing plate 207 from moving downward, and then the second electric slider 202 is controlled to drive the pressing plate 207 to move rightward for a distance, so that the tufts on the carpet 3 are rubbed by the pressing plate 207. At this time, the through groove 20701 simulates the pattern of the sole to increase the friction between the pressing plate 207 and the tufts. Subsequently, the second driving member 203 is controlled to drive the pressing plate 207 to move rightward for a distance, so that the tufts on the carpet 3 are rubbed by the pressing plate 207. 7 moves upward to make the pressing plate 207 leave the carpet 3, and repeats the above operation to realize the simulation of a person's foot wearing shoes stepping on the carpet 3, so as to realize the wear resistance test of the carpet 3. In this process, if the connection between the tufts and the backing is damaged during the above-mentioned detection of the connection degree between the tufts and the backing, but they have not fallen off the backing, then under the pressure of the pressing plate 207, the connection between the tufts and the backing is easily broken and they fall off the backing, resulting in that when the pressing plate 207 moves to the right, the fallen tufts are stuck in the through groove 20701 on the pressing plate 207, so that after the through groove 20701 is filled with tufts, the surface of the pressing plate 207 becomes flat, resulting in the pressing plate 207 being pressed. The friction force on the surface of 207 is reduced, so that when the pressing plate 207 rubs the carpet 3, the wear degree of the tufted blanket on the carpet 3 is reduced, thereby affecting the wear resistance test result of the carpet 3. The following is an explanation of the electrostatic brush 4, the scraper 5 and the collecting box 303 located on the right side. When the electrostatic brush 4, the scraper 5 and the pressing plate 207 are driven by the second electric slider 202 to move rightward to the upper side of the collecting box 303, the servo motor 205 is controlled to drive the rotating shaft 206 and the pressing plate 207 to rotate counterclockwise, and the motor 209 is controlled to drive the electrostatic brush 4 and the scraper 5 to rotate clockwise, so that the pressing plate 207 is in misaligned contact with the electrostatic brush 4 and the scraper 5, and in this process, the electrostatic brush 4 and the scraper 5 scrape the pressure plate 207, so that the scraper 5 is squeezed with the pressure plate 207 during the rotation and deformed. Then, when the scraper 5 passes through the through groove 20701, the scraper 5 returns to its original state, so that the scraper 5 is inserted into the through groove 20701. Then, as the scraper 5 continues to rotate, the scraper 5 will pry the tufts stuck in the through groove 20701, so that the stuck tufts fall off from the through groove 20701, thereby cleaning the tufts stuck in the through groove 20701. Then, the tufts falling off from the scraper 5 will fall downward into the collection box 303, so that the fallen tufts are collected. It should be noted that at this time, the air pump continues to generate suction on the collection box 303 through the connecting plate 302.

[0040] Finally, after the wear resistance test of the carpet 3 is completed, the staff replaces another identical carpet 3, and controls the servo motor 205 to drive the rotating shaft 206 and the pressure plate 207 to rotate counterclockwise based on the view from the front to the back, and rotates the other pressure plate 207 to the position where the original pressure plate 207 is located. Since the number of through grooves 20701 opened on each pressure plate 207 is different, the roughness of the surface of each pressure plate 207 is different, so that the friction between each pressure plate 207 and the tuft is different. Subsequently, the replaced carpet 3 is tested for wear resistance through another pressure plate 207, and the test data is recorded, so as to realize the wear resistance test of the tufts on the carpet 3 under different friction forces under different shoes and different friction forces, so as to avoid a single wear resistance test method, resulting in a single wear resistance test data, thereby affecting the credibility of the wear resistance test data.

[0041] Each collecting box 303 is arranged in a right trapezoidal shape, so that the impurities in the collecting box 303 are gathered at the bottom of the collecting box 303, and the impurities in the collecting box 303 are prevented from being thrown out of the collecting box 303 due to mechanical shaking during the movement of the collecting box 303, causing the impurities in the collecting box 303 to contaminate the carpet 3 and affect the detection of the carpet 3 by the equipment.

[0042] Each through groove 20701 is arranged in an inverted trapezoidal shape; when the pressure plate 207 rubs the tufts on the carpet 3, the contact part between the through groove 20701 and the tufts is inclined, thereby exerting a shoveling effect on the tufts, further improving the detection effect of the degree of connection between the tufts and the backing.

[0043] It also includes a cleaning plate 304; a cleaning plate 304 is fixedly connected to the upper side of each collecting box 303; when the electrostatic brush 4 and the scraper 5 are located on the upper side of the collecting box 303 and rotated by the motor 209, the bristles of the electrostatic brush 4 and the scraper 5 will hit the cleaning plate 304, so that the electrostatic brush 4 and the scraper 5 are squeezed by the cleaning plate 304, so that the bristles on the electrostatic brush 4 are deformed, so that the fluff and fiber debris adhered to the bristles of the electrostatic brush 4 fall off the electrostatic brush 4, and then the suction force generated by the air pump causes the fluff and fiber debris to fall onto the collecting box 303, thereby cleaning the electrostatic brush 4 and avoiding a large amount of fluff and fiber debris remaining in the electrostatic brush 4, which affects the subsequent cleaning of the carpet 3 fiber debris by the electrostatic brush 4.

[0044] Example 2

[0045] On the basis of Example 1, Figure 1 and Figure 5As shown, it also includes a rainy day simulation component, which includes an environmental simulation unit and an extrusion rod 403; the environmental simulation component is connected to the connecting frame 204; two left-right symmetrical extrusion rods 403 are fixed to the connecting frame 204; each extrusion rod 403 is located on the upper side of the adjacent electrostatic brush 4; the pressure plate 207 is made of rubber material.

[0046] The environmental simulation unit includes a first nozzle 401 and a second nozzle 402; a plurality of first nozzles 401 are fixedly connected to the upper left portion of the connecting frame 204; a sandblasting device is arranged outside the detection box 1; the sandblasting device is connected to each first nozzle 401; a plurality of second nozzles 402 are fixedly connected to the upper right portion of the connecting frame 204; a water spraying device is arranged outside the detection box 1; the water spraying device is connected to each second nozzle 402.

[0047] In the process of testing the wear resistance of the carpet 3, a small amount of gravel is sprayed onto the carpet 3 along the first nozzle 401 through the sandblasting equipment, and water is sprayed onto the carpet 3 along the second nozzle 402 through the water spray assembly, so that when the pressing plate 207 rubs the carpet 3, the tufts will be wetted by the water, and the gravel will move with the pressing plate 207, causing the gravel to rub the wetted tufts, thereby increasing the wear degree of the tufts. The above method simulates the situation that a person walks into the house from outside on a rainy day, so that the bottom of the shoes stepping on the carpet 3 is stuck with rainwater and gravel. At this time, when the carpet 3 is simulated on a rainy day, not only the broken The tufts and gravel will also be stuck in the through slot 20701, causing the tufts stuck in the through slot 20701 to become more stable under the support of the gravel, and it is difficult to clean them by the rotating electrostatic brush 4 and the scraper 5. Therefore, the electrostatic brush 4 and the scraper 5 located on the right are used for explanation below. When cleaning the gravel and tufts stuck in the through slot 20701, the second electric slider 202 is controlled to drive the pressing plate 207, the electrostatic brush 4 and the scraper 5 to move to the upper side of the collecting box 303, and then the servo motor 205 is controlled to drive the rotating shaft 206 and the pressing plate 207 to rotate counterclockwise, thereby driving the gravel and tufts stuck in the through slot 20701 to rotate in the same way. At the same time, the servo motor 205 is controlled to drive the rotating shaft 206 and the pressing plate 207 to rotate counterclockwise. The motor 209 drives the electrostatic brush 4 and the scraper 5 to rotate clockwise, so that the pressure plate 207 and the electrostatic brush 4 and the scraper 5 are in misaligned contact. At the same time, during the rotation of the pressure plate 207, the pressure plate 207 will contact the squeezing rod 403, causing the pressure plate 207 to be squeezed by the squeezing rod 403, so that the pressure plate 207 is deformed under the squeezing, causing the contact part between the pressure plate 207 and the squeezing rod 403 to first deform toward the middle of the pressure plate 207, so that the width of the through groove 20701 is reduced, thereby squeezing the gravel and tufts stuck in the through groove 20701, so that the above-mentioned gravel and tufts are loosened after being squeezed, so as to facilitate the subsequent cleaning of the above-mentioned gravel and tufts from the through groove 20701. Slot 20701, then, the pressing plate 207 moves toward the rotating shaft 206, so that the width of the through slot 20701 increases after the pressing plate 207 is deformed, so that the gravel and tufts stuck in the through slot 20701 lose the limitation of the through slot 20701, at this time, the above-mentioned gravel and tufts are cleaned by the rotating electrostatic brush 4 and the scraper 5, so that the above-mentioned gravel and tufts are separated from the through slot 20701, thereby realizing the cleaning of the gravel and tufts stuck in the through slot 20701, avoiding the gravel and tufts stuck in the through slot 20701 from filling the through slot 20701, causing the surface of the pressing plate 207 to become flat, affecting the credibility of the pressing plate 207 in the wear resistance detection of the carpet 3.
