Description

Technical Field

[0001] The present invention relates to the technical field of carpet production detection, and more particularly to a wear resistance detection device for carpets. Background Art

[0002] Carpet is a floor covering made of natural fibers such as cotton, linen, wool, silk, grass yarn, or chemical synthetic fibers, knitted, piled, or woven by hand or mechanical processes. It is one of the arts and crafts with a long history and tradition in the world. It is used to cover the floors of residences, hotels, conference rooms, entertainment venues, gymnasiums, exhibition halls, vehicles, ships, airplanes, etc., and has the effects of reducing noise, heat insulation, and decoration, improving foot feel, preventing slipping, and preventing air pollution.

[0003] Among them, no matter what kind of carpet, in order to obtain sufficient performance parameters and ensure product quality during its design, research and development and actual production process, the carpet needs to be subjected to a series of tests. Among them, since the main function of the carpet is to be stepped on, the trampling performance of the carpet is the key to the quality of the carpet. Since manual trampling tests are time-consuming and labor-intensive, the prior art uses a friction head to continuously rub to simulate the friction damage to the carpet during the trampling process, and then uses mechanical equipment to drive the friction head to continuously rub to detect the abrasion resistance of the carpet, thereby obtaining a judgment on the quality of the carpet.

[0004] For a complete carpet, the carpet has a larger bearing surface and the probability of the carpet edge being stepped on is smaller. Therefore, in actual testing, only the surface area of ​​the carpet needs to be tested. However, in order to facilitate transportation and installation, as well as to facilitate self-assembly by users, many assembled carpets have appeared on the market. Assembled carpets are composed of multiple independent small pieces or modules. These small pieces can be combined together through fasteners, adhesives or other connection methods to form a complete carpet. Assembled carpets are becoming more and more popular in commercial and residential environments due to their flexibility, easy installation and maintenance.

[0005] Therefore, for assembled carpets, after they are assembled into a whole carpet, more edge seams are formed. In actual use, the probability of the carpet edge seams being stepped on is relatively high. Since assembled carpets need to ensure sufficient assembly accuracy, the edges of each single assembled carpet are accurately cut according to the specified trajectory. The assembled carpet mainly includes a surface layer and a bottom layer (the surface layer is a textile material, and the bottom layer is a supporting structure for the surface layer fibers, which fixes the surface layer fibers together to provide additional stability. Synthetic materials such as polypropylene or polyester are usually used, and rubber pads can also be directly used as the bottom layer). Therefore, after cutting, the textile warp and weft of the material at the edge are in a broken state, and the mutual bonding strength between the edge materials is not high, and it is relatively easy to be damaged. Therefore, on the carpet after actual assembly, the carpet seams are easily damaged. Therefore, for this type of carpet, it is also necessary to effectively test the carpet edge.

[0006] In the prior art, in order to simulate the state of carpets after being assembled and laid, four carpets are usually butted together and placed on a test device, and a friction head is used to perform a friction test in the joint area. However, each carpet is mainly glued to the test table by its own glue, and the friction head is continuously moved during the test. Since qualified products are of higher quality and can withstand heavier and greater friction, the main friction head has more relative movement during the actual test, and in order to improve the test efficiency, the movement speed of the friction head is relatively fast. Therefore, repeated friction can easily increase the temperature of the friction area, causing the glue to melt and reduce its viscosity, and the corners of the carpet are prone to warping, which is aggravated by the movement of the friction head, affecting the actual test. Summary of the invention

[0007] The present invention provides a wear resistance testing device for carpets, and aims to solve the following problem: in the prior art, when four carpets are butt-jointed and a friction head is used to perform a friction test in a joint area, the friction head continuously moves during the test, causing friction and heating, which results in a temperature rise, causing the adhesive layer to become less effective and the carpet corners to easily warp, thus affecting the actual test.

DETAILED DESCRIPTION

[0033] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Refer to the instruction manual Figures 1 to 13 A wear resistance detection device for carpets comprises a test bench assembly 1, a main test assembly 2, a sub-test assembly 3, a cleaning assembly 4 and a visual detection assembly 6, wherein the main test assembly 2 is a main simulation test device, and the sub-test assembly 3 is an auxiliary test device. The test bench assembly 1 comprises a turntable 11 and a base 12, wherein the turntable 11 is rotatably arranged on the base 12, and the turntable 11 is used to install carpet samples 5, and at least two groups of carpet samples 5 are arranged in the turntable 11, and the seams of the two groups of carpet samples 5 are arranged in a collinear manner with the rotation center point of the turntable 11, wherein, since the carpet samples 5 are normally laid, the number of carpet samples 5 in this embodiment is preferably four groups, and the seams of two adjacent groups of carpet samples 5 are all arranged in a collinear manner with the rotation center point of the turntable 11, that is, the intersection of the four groups of seams is at the rotation center point of the turntable 11, ensuring that each group of carpet samples 5 is evenly distributed during actual testing, and the carpet samples 5 are composed of a bottom layer 51 and a surface layer 52, and the carpet samples 5 are bonded to the turntable 11 through the adhesive layer at the bottom of the bottom layer 51.

[0035] The main test assembly 2 includes a main friction head 21, a transverse driving member 22 and a first lifting driving member 23. The transverse driving member 22 and the base 12 are installed together on the same frame. The main friction head 21 is arranged above the turntable 11. The main friction head 21 is installed on the output end of the first lifting driving member 23. The first lifting driving member 23 is installed on the output end of the transverse driving member 22. The first lifting driving member 23 is used to drive the main friction head 21 to move up and down above the turntable 11 to approach or move away from the carpet sample 5. The transverse driving member 22 is used to drive the main friction head 21 to move laterally on the surface of the carpet sample 5, and the above-mentioned transverse movement trajectory is set through the rotation center point of the turntable 11.

[0036] A heat dissipation cavity 13 is provided at the center of the turntable 11, and a heat conducting plate 14 is installed on the heat dissipation cavity 13. The top surface of the heat conducting plate 14 is aligned with the top surface of the turntable 11. A circulating cooling liquid is provided in the heat dissipation cavity 13. The circulating cooling liquid is preferably low-temperature water. The top surface of the turntable 11 and the top surface of the heat conducting plate 14 are both provided with joint markings, as shown in the attached manual. Figure 1 and Fig.11 As shown by the dotted lines in FIG. 1 , when installing each carpet sample 5 , two adjacent seams correspond to the above-mentioned seam marking lines respectively, ensuring that the seams between two adjacent groups of carpet samples 5 can be accurately colinear with the rotation center point of the turntable 11 .

[0037] The visual inspection component 6 is arranged above the turntable 11. The visual inspection component 6 includes a CCD visual recognition camera. The CCD visual recognition camera is used to collect and recognize the surface conditions of each group of carpet samples 5 on the turntable 11 after the test. In this embodiment, the transverse driving member 22 needs to span the top of the turntable 11. Therefore, the visual inspection component 6 can be installed on the transverse driving member 22. For details, please refer to the attached manual. Figure 4 , and since the visual recognition system is already a mature detection technology, this embodiment will not be explained in detail.

[0038] During the actual test, each group of carpet samples 5 is first mounted at a specified position on the turntable 11 so that the joint corresponds to the rotation center point of the turntable 11, and then the first lifting drive 23 is controlled to drive the main friction head 21 to descend so that the main friction head 21 contacts the carpet sample 5 and applies the pressure required for the test (a pressure sensor can be provided between the main friction head 21 and the first lifting drive 23 to determine the actual pressure between the main friction head 21 and the carpet sample 5, so as to facilitate the adjustment of the first lifting drive 23), and then the transverse driving member 22 is controlled to drive the main friction head 21 to move back and forth to form friction on the surface of the carpet sample 5. Through the above-mentioned setting of the joints of each group of carpet samples 5, it can be ensured that each movement of the main friction head 21 can pass through the joint, thereby realizing the priority simulation test of the joint.

[0039] Among them, this embodiment provides two test modes, one is to drive the main friction head 21 to reciprocate along the seam of the carpet sample 5. During the test, the turntable 11 does not move, and the simulation test is mainly performed on the seam. The turntable 11 only rotates a certain angle regularly to adjust other seams to adapt to the main friction head 21. The other is to drive the main friction head 21 to move back and forth while continuously driving the turntable 11 to rotate (it can continuously rotate in the same direction or reciprocate), so that the main friction head 21 can perform simulation tests on other areas in addition to the seam. Through the above test method, the actual use of the spliced ​​carpet sample 5 can be truly simulated, the quality of the edge seam of the carpet sample 5 can be effectively judged, and the quality of the carpet sample 5 during the research and development or production process can be ensured.

[0040] In the above-mentioned embodiments, refer to the attached specification. Figure 7 A rotating bearing is arranged between the turntable 11 and the base 12, a turntable driver 15 is installed in the turntable 11, a bevel gear set is arranged between the output end of the turntable driver 15 and the turntable 11, and the turntable driver 15 drives the turntable 11 to rotate through the bevel gear set.

[0041] Generally speaking, qualified products are of higher quality and can withstand heavier and greater friction. Therefore, during actual testing, the main friction head 21 has more relative movement, and in order to improve the test efficiency, the movement speed of the main friction head 21 is relatively fast. Therefore, repeated friction is likely to increase the temperature of the friction area, causing the viscose to melt and reduce its viscosity, and even causing damage to the carpet sample 5 and the main friction head 21. Therefore, this embodiment provides a heat dissipation cavity 13 in the turntable 11, so that cooling liquid circulates through the heat dissipation cavity 13 to conduct heat to the carpet sample 5 on the surface of the turntable 11, thereby achieving a cooling effect, avoiding the carpet sample 5 from having a test error or even damage caused by excessive temperature in the friction area of ​​the carpet sample 5, while ensuring the detection efficiency, and improving the accuracy of the test results and ensuring the safety of the test process.

[0042] In the above embodiment, since the main test component 2 is mainly used to test the joints of the carpet sample 5, for products with demand, it is also necessary to perform conventional tests on the carpet sample 5, that is, to use the auxiliary test component 3 to test the surface of the carpet sample 5, wherein, refer to the attached manual Figure 3 and Figure 4 The auxiliary test assembly 3 includes an auxiliary friction head 31 and a second lifting driver 32. The auxiliary friction head 31 is arranged above the turntable 11. The second lifting driver 32 and the base 12 are installed on the same frame. The auxiliary friction head 31 is installed on the output end of the second lifting driver 32. The second lifting driver 32 is used to drive the auxiliary friction head 31 to move up and down to approach or move away from the carpet sample 5, and the auxiliary friction head 31 is arranged away from the rotation center point of the turntable 11. When the auxiliary test assembly 3 is used for testing, the auxiliary friction head 31 is controlled by the second lifting driver 32 to approach the carpet sample 5 and apply pressure to the carpet sample 5. The turntable 11 is driven to rotate by the turntable driver 15, so that the carpet sample 5 and the auxiliary friction head 31 produce relative friction movement to realize friction simulation.

[0043] It should be noted that the auxiliary friction head 31 and the main friction head 21 are made of the same material and structure, and are both made of rubber material simulating the material of the sole. A pressure sensor is also provided between the auxiliary friction head 31 and the output end of the second lifting drive 32, so as to accurately control the pressure between the auxiliary friction head 31 and the carpet sample 5. The action area of ​​the auxiliary friction head 31 is mainly the position on the surface of the carpet sample 5 away from the rotation center point of the turntable 11. Therefore, the actual simulation mainly simulates the wear of the bottom layer 51 on the surface of the carpet sample 5.

[0044] In the above embodiment, if the test is performed in a stationary or reciprocating manner with the turntable 11, a conventional circulation method can be used for the circulation of the cooling liquid in the heat dissipation chamber 13, with the help of a hose to adapt to the reciprocating rotation of the turntable 11. However, for some test requirements, the reciprocating rotation amplitude of the turntable 11 is small, and the friction direction formed is variable, which affects the test effect. Therefore, in order to ensure the uniformity of the friction direction and obtain accurate test results, in actual testing, it is preferred to drive the turntable 11 to rotate continuously. At this time, the conventional circulation method cannot adapt to the rotating turntable 11. For this reason, refer to the attached manual. Figure 7 and Figure 8 The present embodiment also provides the following technical solutions. Specifically, the interior of the turntable 11 is provided with a liquid inlet channel 131 and a liquid outlet channel 132, both of which are connected to the heat dissipation cavity 13. The bottom of the turntable 11 is provided with a slot, and the interior of the base 12 is provided with a liquid supply base 16, which is rotatably inserted into the slot at the bottom of the turntable 11. The interior of the liquid supply base 16 is provided with a liquid infusion tube 161 and a liquid extraction tube 162, and the ends of the liquid infusion tube 161 and the liquid extraction tube 162 are The opening extends to the side wall of the liquid supply base 16, and the ports of the infusion tube 161 and the extraction tube 162 are staggered in the height direction. The first annular groove 111 and the second annular groove 112 are provided on the inner wall of the slot of the turntable 11. The first annular groove 111 is provided corresponding to the infusion tube 161, the second annular groove 112 is provided corresponding to the extraction tube 162, and the second annular groove 112 is provided corresponding to the extraction tube 162. With the help of the transfer docking of the first annular groove 111 and the second annular groove 112, no matter how the turntable 11 rotates, the liquid inlet passage 111 can be The channel 131 and the liquid infusion tube 161, as well as the liquid outlet channel 132 and the liquid extraction tube 162 can be interconnected. A rotating sealing structure (such as a rubber ring) is provided between the first annular groove 111 and the outer wall of the liquid supply base 16, as well as between the second annular groove 112 and the outer wall of the liquid extraction tube 162. The liquid inlet channel 131 is connected to the first annular groove 111, and the liquid outlet channel 132 is connected to the second annular groove 112. The liquid infusion tube 161 is connected to a low-temperature liquid source, which includes a low-temperature liquid cooling body storage box and a liquid supply pump. The liquid supply pump is used to provide low-temperature cooling liquid to the liquid infusion tube 161, so that the low-temperature cooling liquid can be continuously input into the heat transfer plate 14 without affecting the rotation of the turntable 11. After absorbing the heat generated by the friction of the carpet sample 5, the cooling liquid flows out through the liquid outlet channel 132 and the liquid extraction tube 162, and then dissipates heat and cools down. The cooling liquid after heat dissipation and cooling down returns to the low-temperature liquid cooling body storage box for recycling, thereby forming a circulating cooling liquid in the heat dissipation cavity 13.

[0045] In the above embodiment, for some carpet products, in order to improve their own strength and quality, rubber or plastic materials are used to make the bottom layer 51, and some bottom layers 51 are thicker, and the bottom layer 51 itself has a poor thermal conductivity, and the actual friction mainly acts on the surface layer 52, which leads to poor actual heat dissipation effect. For this reason, this embodiment also provides the following technical solutions, refer to the attached manual Fig.10 and Fig.11 A heat-conducting pin 141 is provided in the heat-conducting plate 14, and the bottom end of the heat-conducting pin 141 is connected to a pin fixing member 143. The pin fixing member 143 is in contact with the circulating cooling liquid in the heat dissipation cavity 13. The top end of the heat-conducting pin 141 is inserted into the bottom layer 51. The heat-conducting pin 141 and the pin fixing member 143 are preferably a metal heat-conducting structure, so that the heat above the bottom layer 51 can be quickly conducted through the heat-conducting pin 141, thereby improving the cooling effect.

[0046] In addition, a guide cavity 142 is provided inside the heat conducting plate 14, the bottom of which is connected to the heat dissipation cavity 13, and the pin fixing part 143 is slidably installed in the guide cavity 142 to form a piston structure (a tiny air gap structure is provided in the space above the pin fixing part 143 in the guide cavity 142 corresponding to the pin fixing part 143, and the space above the pin fixing part 143 is exhausted when the pin fixing part 143 moves upward to avoid excessive air pressure in the upper part, but since the air gap structure is small, it is not demonstrated in this embodiment), a pressure control valve is provided on the liquid extraction tube 162, the top of the heat conducting pin 141 is inclined toward the rotation center point of the turntable 11, the guide cavity 142 is an inclined guide structure, and the inclination direction of the guide cavity 142 is the same as the inclination direction of the heat conducting pin 141. In actual use, the carpet sample 5 is bonded to the turntable After the heat dissipation platform 11 is placed on the platform 11, low-temperature cooling liquid is input into the heat dissipation chamber 13, and the output of the liquid extraction pipe 162 is controlled by the pressure control valve, thereby ensuring that the liquid in the heat dissipation chamber 13 has a certain pressure, so that the pressure pushes the pin fixing member 143 upward, thereby causing the heat conductive pin 141 to be obliquely inserted into the bottom layer 51, thereby realizing the automatic operation of the heat conductive pin 141, and the heat conductive pin 141 is tilted. After the heat conductive pin 141 is inserted into the bottom layer 51, a positioning support can be provided for the bottom layer 51, and in the process of the main friction head 21 moving along the seam of the carpet sample 5 toward the surface of the carpet sample 5, a strong support is provided for the carpet sample 5, and even in the case of failure of the adhesive layer at the bottom of the bottom layer 51, the edge of the carpet sample 5 will not be turned up, thereby further ensuring the safety of the test process.

[0047] Furthermore, in the above embodiment, since the thickness of the bottom layer 51 in different carpet samples 5 is different during the actual test, and the thermal conductive pin 141 is not suitable to penetrate the bottom layer 51, the present embodiment also provides a scheme for controlling the extension amount of the thermal conductive pin 141. An adjusting screw 144 is provided at the bottom of the guide cavity 142. A threaded sleeve structure is fixedly installed at the bottom of the guide cavity 142 through a bracket structure. The guide cavity 142 passes through the threaded sleeve structure and is threadedly connected with the threaded sleeve structure. The adjusting screw 144 is connected to the pin fixing member 143 through a pulling wire 145, so that the adjusting screw 144 can be rotated in advance to adjust the height of the adjusting screw 144. By pulling the pin fixing member 143 with the pulling wire 145, the maximum extension amount of the thermal conductive pin 141 is limited to adapt to the actual thickness of the bottom layer 51 during the test.

[0048] In the above embodiment, the heat generated by friction can be processed in time during the test process, so the overall temperature of each structure is relatively low during the test process, and the continuous movement of the main friction head 21 is likely to generate static electricity, causing the fiber structure worn off on the surface layer 52 to be easily adsorbed on the surface of the main friction head 21. If there are many adsorbed fiber structures, an obstruction layer will be formed at the bottom of the main friction head 21, which will affect the actual friction effect of the surface layer 52. For this reason, this embodiment also provides the following technical solutions, specifically, refer to the attached manual Figure 1 and Fig.13 The cleaning component 4 includes an air nozzle 41, a third lifting driver 42 and an air nozzle rotating driver 43. The third lifting driver 42 and the base 12 are installed on the same frame. The air nozzle 41 is connected to the output end of the third lifting driver 42 through the air nozzle rotating driver 43. The third lifting driver 42 is used to drive the air nozzle 41 to rise and fall. The air nozzle rotating driver 43 is used to drive the air nozzle 41 to flip. The air nozzle 41 is connected to the air pump structure. In the actual test process, the main friction head 21 can be regularly driven to rise, and the air nozzle 41 can be driven to flip to an angle corresponding to the bottom of the main friction head 21, so that the main friction head 21 is blown away by the air nozzle 41. The fiber structure adsorbed by static electricity on the surface of the main friction head 21 is blown away, and the air source used by the main friction head 21 is a high-humidity air source, which helps to eliminate static electricity when blowing out. In addition, during normal testing, the air nozzle 41 can also be controlled to align with the surface of the carpet sample 5, especially the friction area of ​​the carpet sample 5, so that the worn and broken fibers of the surface layer 52 can be blown away from the friction area in time to reduce the impact on the test.

[0049] It should be noted that, for the auxiliary friction head 31, a driving scheme for the air nozzle 41 can be added to increase the degree of freedom of the air nozzle 41, so that the air nozzle 41 can also be aligned with the auxiliary friction head 31 for processing. The various types of lifting and moving driving devices used in this embodiment all adopt commonly used linear motors or cylinder hydraulic cylinders and other structures. The relevant rotating driving devices can adopt motors and other structures. In addition, the specific structure of each driving device will not be explained in detail in this embodiment.

[0050] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
