Description

Technical Field

[0001] The invention relates to the technical field of carpet processing, in particular to a simulation device for carpet performance testing. Background Art

[0002] Carpets are common daily necessities. They are floor coverings made of natural fibers such as cotton, linen, wool, silk, and grass yarn, or chemical synthetic fibers, which are knitted, planted, or woven by hand or mechanical processes.

[0003] At present, after the carpet fabric is processed, it is often necessary to test various properties of the carpet to ensure the quality of the carpet. In the prior art, there are two types of carpet wear resistance tests. One is to rub the carpet manually with a friction block. The friction force and speed are difficult to standardize, resulting in inaccurate test data and low practicality. The other is to use existing equipment to move the friction block back and forth on the carpet for friction. Although the friction force and speed are standardized, the test conditions are too single and cannot actually simulate the various factors that occur during the use of the carpet, which leads to incomplete and inaccurate test data. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings that the friction force and speed of the carpet are difficult to standardize and the test data is not accurate enough due to the manual test of the carpet's wear resistance, and the various factors that may occur during the use of the carpet cannot be actually simulated when the carpet is tested using existing equipment, which leads to incomplete and inaccurate test data.

[0052] The power mechanism includes an electric slide rail 101 and an electric slider 102; the inner rear wall of the cover 1 is bolted with two electric slide rails 101; each electric slide rail 101 is slidably connected with an electric slider 102; all the electric sliders 102 are fixedly connected to the connecting plate 6.

[0053] The working steps of this embodiment are:

[0054] The following rotations are from front to back, from top to bottom, and from right to left.

[0055] The first step is to place the simulation device for carpet performance testing at a desired location when in use;

[0056] In the second step, the operator connects an external power source to the electric slide rail 101, the electric push rod 1 201, the electric push rod 2 302, the servo motor 1 306, the servo motor 2 402 and the electric valve. A detachable mobile power source is provided on the inner side of each tension roller 9 to supply power to the annular slide rail 203. Before testing the carpet, the cover 404 of the storage barrel 401 is opened, and impurities such as sand or soil are added to the storage barrel 401. Then, the cover 404 is put back on the storage barrel 401. Then, the operator prepares a ring-shaped carpet connected end to end in advance;

[0057] In the prior art, since the wear resistance test of the carpet is conducted manually, the friction force and speed are difficult to be standardized, and the test data is not accurate enough. The wear resistance test of the carpet by the existing equipment is also unable to actually simulate the various factors that occur during the use of the carpet, which leads to incomplete test data and inaccurate data. Therefore, the operator grabs the handle 20001, opens the protective door 2 upward, and then controls the two electric sliders 102 to move on the electric slide rail 101. The two electric sliders 102 drive the connecting plate 6, the H-shaped plate 7, the limit plate 8, the tensioning roller 9, the partition plate 10 and the tensioning mechanism to move upward together. When the two electric sliders 102 move to the electric slide rail, the two electric sliders 102 move upward. After reaching the top of the rail 101, the two electric sliders 102 are controlled to stop moving, and then the telescopic parts of the two electric push rods 201 are controlled to contract, driving the slip ring 202, the right tensioning roller 9 and the tensioning mechanism to move to the left together, so that the right tensioning roller 9 slides in the two waist-shaped grooves 80001, so that the distance between the two tensioning rollers 9 becomes smaller, and then the carpet is put on the two tensioning rollers 9 and the partition 10, and the annular carpet is supported by the partition 10 to prevent the annular carpet from being suspended in the air. After the annular carpet is placed, the telescopic parts of the two electric push rods 201 are controlled to be pushed out, driving the connected parts and the right tensioning roller 9 to move to the right, so that the annular carpet put on the two tensioning rollers 9 is tightened;

[0058] Then control the two electric sliders 102 to drive the connected parts and the carpet to move downward together, move the two tensioning rollers 9 to the two receiving plates 5, and then grab the cross bar 407 and move it upward on the outer surface of the support column 406, driving the T-bar 408, the mounting block 409, the wear-resistant disk 410 and the designated bolts 411 to move upward together. After the wear-resistant disk 410 is higher than the carpet, the cross bar 407, the T-bar 408, the mounting block 409, the wear-resistant disk 410 and the designated bolts 411 are pushed to rotate onto the carpet with the support column 406 as the axis, and then manually fix the cross bar 407 on the support column 406, and twist the designated bolts 411 on the T-bar 408, and the two designated bolts 411 move downward on the cross bar 407, thereby driving the T-bar 408, the mounting block 409 and the wear-resistant disk 410 to move downward until the wear-resistant disk 410 is pressed on the upper surface of the carpet, and the two designated bolts 411 are locked.

[0059] In the third step, after the wear-resistant disc 410 contacts the carpet, the operator closes the protective door 2, controls the telescopic parts of the two electric push rods 302 to push out, drives the mounting plate 303, the fixing frame 304, the conveying roller 305 and the servo motor 306 to move to the left together, makes the conveying roller 305 contact the carpet, and then controls the output shaft of the servo motor 306 to drive the conveying roller 305 to rotate clockwise, and the conveying roller 305 carries the carpet to perform counterclockwise circular motion. As the carpet continues to move, the wear-resistant disc 410 continues to rub the carpet, thus realizing the most basic wear resistance test of the carpet;

[0060] During the continuous rotation of the carpet by the conveying roller 305, the carpet will gradually move forward because the front of the two tensioning rollers 9 lacks restriction, thereby affecting the wear resistance test of the carpet. Therefore, all the annular sliders 204 on the two annular slide rails 203 are controlled to slide with the blocks 205, and the four blocks 205 distributed in a fan shape are changed into four blocks 205 distributed in an annular array, such as Fig.11 As shown, the carpet on the two tensioning rollers 9 is limited to prevent the carpet from gradually moving forward during the cyclic rotation process, thereby affecting the wear resistance test of the carpet;

[0061] During the basic wear resistance test of the carpet, the output shaft of the servo motor 2 402 can be controlled to rotate clockwise, driving the storage barrel 401, the discharge pipe 403 and the cover 404 to rotate clockwise by 90 degrees. After the discharge pipe 403 rotates to the top of the carpet, the output shaft of the servo motor 2 402 is controlled to continuously swing clockwise and then counterclockwise, so that the discharge pipe 403 can swing back and forth on the carpet. At the same time, the electric valve in the discharge pipe 403 is controlled to open, so that the discharge pipe 403 can continuously swing the sand or mud in the storage barrel 401. Impurities such as soil are scattered on the continuously rotating carpet. Under the reciprocating swing of the discharge pipe 403 and the continuous rotation of the carpet, the scattered impurities such as sand or soil are randomly distributed on the outer surface of the carpet. In this way, the wear resistance test of the carpet is more in line with the existing actual scene, that is, the existing carpet will be rubbed by impurities such as sand or soil carried on people's shoes during use. The material in the storage barrel 401 can be replaced according to the test requirements, thereby realizing the simulation effect of diversified scenes, which is convenient for operators to collect sufficient test data and ensure the accuracy of the results.

[0062] Step 4. When the wear test of the carpet is completed, the operator grabs the handle 20001, opens the protective door 2, and then controls the output shaft of the servo motor 1 306 to stop rotating. The output shaft of the servo motor 2 402 drives the connected parts to rotate counterclockwise to reset. The telescopic parts of the two electric push rods 2 302 shrink, driving the connected parts to reset to the right. Then, the two designated bolts 411 are manually adjusted to move the T-bar 408, the mounting block 409 and the wear-resistant plate 410 upward and no longer contact the carpet. Then, the cross bar 407 fixed on the support column 406 is loosened, and the cross bar 407, the T-bar 408, the mounting block 409 and the wear-resistant plate 410 are moved to the right. 409, the wear-resistant disc 410 and the designated bolt 411 are rotated to the left side of the carpet and placed downward on the left side of the collecting box 3. Then the two electric sliders 102 are controlled to drive the connected parts and the carpet to move upward. After the carpet is moved to the top, all the annular sliders 204 on each annular slide rail 203 are controlled to drive the block 205 to reset, so that the four blocks 205 on the two tensioning rollers 9 are changed back to the fan shape that fits each other again. Then the telescopic parts of the two electric push rods 201 are controlled to shrink, driving the connected parts to move to the left, and the carpet is no longer tightened. Then the operator takes the carpet off the two tensioning rollers 9.

[0067] The working principle of this embodiment is:

[0068] In step 3 of embodiment 1: the operator connects an external power source to the electric push rod 3 412, the electric push rod 4 501 and the servo motor 3 504, connects an external water pipe to the hollow tube 503, and connects an external cleaning liquid pipe to the nozzle 506. Since the carpet needs to test a variety of performance data, and the existing equipment can only test a single performance of the carpet, different performance tests need to be tested on different equipment. This not only takes a long time to test and has low work efficiency, but also requires a lot of cost to purchase test equipment. Therefore, when testing the anti-slip performance of the carpet, the wear resistance test of the carpet needs to be completed. After the wear resistance test of the carpet is completed, and the wear-resistant disc 410 is still pressed on the carpet, the conveyor When the structure is in the reset state and the limit unit is also in the initial contracted state, the telescopic part of the electric push rod 412 is controlled to be pushed out, driving the slide plate 40702, the T-bar 408, the mounting block 409, the wear-resistant disc 410 and the designated bolt 411 to move forward together, and the wear-resistant disc 410 pushes the carpet forward on the two tensioning rollers 9 and the partition 10 to achieve the anti-slip performance test effect after the wear resistance test of the carpet. The anti-slip performance test of the carpet after the wear resistance test is carried out, just like simulating the anti-slip performance test of the carpet after the wear in the existing use process. The operator observes the moving distance of the carpet on the two tensioning rollers 9 and the partition 10, evaluates the anti-slip performance of the carpet, and ensures whether it achieves the anti-slip effect.

[0069] It should be noted that before the wear resistance test of the carpet is carried out, the anti-skid performance test of the carpet can be carried out according to the above steps, just like simulating the anti-skid performance test of the new carpet in the existing use process. If the operator feels that it is not accurate enough, the position and angle of the wear-resistant plate 410 can be adjusted to adapt to the anti-skid performance test at different angles. At the same time, water can be added to the carpet and the anti-skid performance test can be carried out again, so as to adapt to different scenarios for anti-skid detection and improve the reliability of the detection data.

[0070] When testing the cleanability of a carpet, a carpet with stains is needed, and a carpet that has been tested for wear resistance is suitable. There are a lot of stains such as sand or soil remaining on it. Therefore, after the carpet has been tested for wear resistance, the operator manually and electrically controls the friction mechanism to reset, while other mechanisms work as usual. For example, the output shaft of the servo motor 306 continues to rotate, and then controls the multiple nozzles of the nozzle 506 to spray the cleaning liquid on the carpet. After the carpet rotates for one circle, the carpet will be covered with cleaning liquid, and then control the multiple nozzles to stop spraying the cleaning liquid, and then control the telescopic parts of the two electric push rods 4 501 to push out, drive the fixed frame 2 502, the hollow tube 503 and the servo motor 3 504 to move toward the carpet, so that the hollow tube 503 can move toward the carpet. The bristles on the outer surface of the tube 503 are in contact with the outer surface of the carpet, and then the output shaft of the servo motor three 504 is controlled to rotate counterclockwise, driving the hollow tube 503 to rotate counterclockwise, and the outer surface of the carpet is scrubbed by the bristles on the hollow tube 503. At the same time, during the scrubbing process, the external water pipe is controlled to transport clean water into the hollow tube 503, and the clean water is sprayed onto the outer surface of the carpet through a number of spray holes on the hollow tube 503. Under the flushing action of the bristles and clean water, impurities such as sand or soil attached to the carpet are cleaned. After the carpet rotates consistently for two weeks, the cleaning performance of the carpet is tested. The operator observes the cleanliness of the outer surface of the carpet, evaluates the difficulty of cleaning the carpet, and ensures whether it is easy to maintain.

[0071] When testing the tensile strength of a carpet, the operator needs to prepare a carpet of appropriate length in the shape of a long strip, and then place the long strip of carpet on two tensioning rollers 9, with both ends of the long strip of carpet in contact with the outer surface of the tensioning roller 9, and then control the telescopic parts of all electric push rods 6 603 to be pushed out, driving the two pressure plates 604 to move to opposite sides, squeezing the carpet in contact with the outer surface of the tensioning roller 9, so that the two ends of the long strip of carpet are fixed on the two tensioning rollers 9, and then control the telescopic part of the electric push rod 5 601 to be pushed out, driving the slip ring 2 602, the tensioning roller 9 on the left, the limit unit, the fixed plate 80003 and one end of the carpet to move to the left. In the process of continuous pulling, the tension applied to the carpet is detected by the tension sensor until the carpet breaks. The tension sensor collects accurate tension data, thereby achieving the effect of testing the tensile strength performance of the carpet.

[0072] Example 3

[0073] On the basis of Example 1, Figure 2 and Fig.10As shown, it also includes a protection mechanism, and the collection box 3 is connected to the protection mechanism; the protection mechanism includes a round rod 605, a protection plate 606, a fixed block 607, a rotating block 608, a second mounting plate 609 and a folding canvas 610; the left part of the collection box 3 is rotatably connected to the round rod 605; the middle part of the round rod 605 is fixedly connected to the protection plate 606; the front part of the round rod 605 is fixedly connected to the fixed block 607; the lower part of the fixed block 607 is rotatably connected to the rotating block 608, and the rotating block 608 is clamped with the leftmost grid bar 4; the right part of the collection box 3 is fixedly connected to the second mounting plate 609; the second mounting plate 609 is provided with a guide groove 60901; the folding canvas 610 is slidably connected in the guide groove 60901; a plurality of support bars are provided on the folding canvas 610; the folding canvas 610 is provided with a pull groove 61001.

[0074] Furthermore, in order to prevent the folded canvas 610 from being knocked over by the broken carpet, a baffle is provided on the inner wall of the protective door 2, and the baffle is located on the right side of the second mounting plate 609.

[0075] The working principle of this embodiment is:

[0076] During the tensile strength test of the carpet in Example 2: since the carpet may break during continuous pulling, and at the moment of breaking, the carpet will impact the conveying mechanism, friction mechanism and cleaning mechanism, thereby causing damage to the impacted components. Therefore, before the tensile strength and elongation at break test of the carpet, the operator first rotates the rotating block 608 to separate the rotating block 608 from the leftmost grid bar 4, and lays down the vertical protective plate 606 to become horizontal, so that it covers the left friction unit to protect the friction unit, and then grabs the pulling groove 61001 to pull the folding canvas 610 forward in the guide groove 60901 to unfold it, to protect the conveying mechanism, friction mechanism and cleaning mechanism, and prevent the conveying mechanism, friction mechanism and cleaning mechanism from being damaged by the broken carpet. After the folding canvas 610 is fully unfolded, the protective door 2 is closed, and the unfolded folding canvas 610 is limited by the blocking bar set in the protective door 2 to prevent the folding canvas 610 from being hit and tipped over by the broken carpet.

[0077] It should be noted that during the wear resistance test of the carpet, since the carpet rotates counterclockwise in a cycle, the wear-resistant disk 410 continuously rubs the carpet, causing impurities such as sand and soil to splash to the left as the carpet rotates counterclockwise, which will pollute the interior of the cover 1. The splashing sand, soil and other impurities are intercepted by the vertical protective plate 606 to prevent sand, soil and water droplets on the carpet from splashing to the outside of the collection box 3 and polluting the interior of the cover 1. At the same time, when conducting a cleaning performance test, the vertical protective plate 606 can also intercept water droplets splashing to the left.
