Description

Technical Field

[0001] The utility model belongs to the technical field of sofa fabric detection, and in particular relates to a sofa fabric wear resistance detection device. Background Art

[0002] Sofa fabric is the surface fabric used to make sofas. Before making the sofa, the sofa fabric needs to be tested for wear resistance. The wear resistance of the fabric refers to the ability of the fabric to maintain its original quality and appearance and not easily damaged or faded when subjected to external friction or wear. If the wear resistance of the sofa fabric is not up to standard, then after the sofa is made, people are prone to pilling during use, which affects people's user experience, thereby causing after-sales problems and affecting word of mouth.

[0003] Among them, Chinese patent CN202221783802.0 discloses a sofa fabric wear resistance detection device, including a wear resistance detection device body, a clamping mechanism, a moving mechanism and a grinding mechanism. The clamping mechanism is located at the top of the moving mechanism, the moving mechanism is located at the top of the wear resistance detection device body, and the grinding mechanism is located at the top of the wear resistance detection device body. The clamping mechanism includes a through hole, a connecting rod, a push rod, a threaded rod, a motor, a connecting ring and a screw rod. The through hole is fixedly arranged at the top of the moving mechanism, and the number of the through holes is several.

[0004] Since traditional testing tools are fixed on the machine, when polishing the surface of the sofa fabric, only a single position can be polished and the polishing position cannot be changed. As a result, the test data is one-sided and cannot reflect the overall wear resistance of the sofa fabric.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figure 1-Figure 5 As shown, the utility model is a sofa fabric wear resistance detection device, comprising a workbench 1, the top of the workbench 1 is connected to two vertical boards 4, and a mixing component and a shrinking component 3 are respectively provided above the workbench 1, the mixing component is used to move left and right between the two vertical boards 4 to perform wear resistance detection on the sofa fabric, and the shrinking component 3 is used to press the sofa fabric tightly for position limiting, the mixing component includes a second driving source 5 and a detection component 2, wherein the second driving source 5 is arranged on one side of one of the vertical boards 4, and the power output end of the second driving source 5 is connected to the detection component 2, the top of the workbench 1 is connected to a placing table 6, and the top of the workbench 1 is connected to two support plates 7;

[0031] The second driving source 5 drives the detection component 2 to perform horizontal translation movement to the left and right, so that the detection component 2 can perform wear resistance detection on the sofa fabric after being pressed and limited by the shrinking component 3.

[0032] First, the sofa fabric to be tested for wear resistance is placed on the placement table 6, and then the shrinking component 3 is pushed outward to tuck the excess part of the sofa fabric downward between the shrinking components 3. Then, the shrinking component 3 is elastically contracted to tighten the corners of the sofa fabric and limit the position. Then, the second driving source 5 is used to drive the detection component 2 to operate. The wear resistance of the sofa fabric can be tested by the detection component 2. At the same time, by controlling the left and right translation movement of the detection component 2, double testing can be performed on different positions of the sofa fabric to improve the testing effect. After the sofa fabric testing is completed, the pressed sofa fabric can be removed by pushing the shrinking component 3, which is easy to operate.

[0033] The detection component 2 facilitates the wear resistance test of the sofa fabric, and the detection position can be adjusted by horizontal movement left and right, so that the wear resistance test can be performed on multiple positions of the sofa fabric. This helps to observe the wear resistance of the sofa fabric through multiple tests, which helps to improve the accuracy of the wear resistance test. The contraction component 3 facilitates the position limiting of the sofa fabric to prevent displacement during the wear resistance test of the sofa fabric, thereby improving the stability of the wear resistance test.

[0034] In one embodiment, for the above-mentioned detection component 2, it includes a connecting screw 21, a first driving source 23, two connecting rods 25 and two limit plates 27. The connecting screw 21 is arranged on the power output end of the second driving source 5. The surface of the connecting screw 21 is threadedly connected to the adjustment block 22 through a screw nut. The first driving source 23 is arranged at the bottom end of the adjusting block 22. The power output end of the first driving source 23 is connected to a detection tooling 24. The two connecting rods 25 are respectively arranged on the front and back of the adjusting block 22. One end of the two connecting rods 25 is connected to a slider 26, and the two limit plates 27 are both arranged between the two vertical plates 4.

[0035] First, place the sofa fabric that needs to be tested for wear resistance on the placement table 6, then push the shrinkage component 3 outward, tuck the excess position of the sofa fabric downward between the shrinkage components 3, and then use the elastic shrinkage effect to make the shrinkage component 3 cooperate with the placement table 6 to tighten the corner position of the sofa fabric. Then, drive the connecting screw 21 to rotate through the second driving source 5, so that when the connecting screw 21 rotates, it will drive the adjustment block 22 threadedly connected to it to move horizontally to the left at this time, and then drive the detection tooling 24 downward through the first driving source 23 to polish the sofa fabric, thereby performing a wear resistance test on the sofa fabric below, and then when it is necessary to change the polishing position to test the wear resistance of the sofa fabric again, the connecting screw 21 is used to drive the adjusting block 22 threadedly connected to it to move horizontally to the left at this time. The rod 21 drives the adjusting block 22 to move left or right. Here, the left movement is described. At this time, the detection tooling 24 is driven to move left as a whole to perform wear resistance testing on different positions of the sofa fabric. Performing wear resistance testing on multiple locations of the sofa fabric helps to improve the effect of sofa fabric testing. When the adjusting block 22 moves left or right, the two sliders 26 slide inside the rectangular grooves opened in the two limit plates 27, thereby providing support for the adjusting block 22, thereby improving the stability of the movement of the adjusting block 22 and preventing the adjusting block 22 from shaking or being unstable when the wear resistance testing of the sofa fabric is completed. After the sofa fabric testing is completed, the pressed sofa fabric can be removed by toggling the retraction component 3, which is easy to operate.

[0036] By connecting the screw rod 21, it is easy to drive the adjustment block 22 to move horizontally to the left or right, and by the first driving source 23, it is easy to control the detection tooling 24 to move up and down, so that it can fit with the sofa fabric and thus perform wear resistance testing on the sofa fabric. By sliding the two sliders 26 inside the rectangular groove, it is easy to provide a stable support force for the side of the adjustment block 22, thereby improving the stability of the movement of the adjustment block 22 and preventing the adjustment block 22 from shaking or being unstable when the wear resistance of the sofa fabric is tested.

[0037] In addition, in specific applications, the detection method of the detection tooling 24 is polishing. The driving motor drives the polishing disc to rotate and contact the sofa fabric to polish it, so that the staff can identify whether the sofa fabric is pilling with the naked eye to obtain the wear resistance test results.

[0038] In one embodiment, for the above-mentioned connecting screw rod 21, one end of the connecting screw rod 21 is rotatably connected to one side of the other vertical plate 4 through a bearing, thereby improving the rotation stability of the connecting screw rod 21 and further improving the stability of the wear resistance testing of the sofa fabric.

[0039] In one embodiment, for the above-mentioned limit plates 27, rectangular grooves are opened on the inner sides of the two limit plates 27, and the surfaces of the two sliders 26 are respectively slidably connected to the inner sides of the two rectangular grooves, thereby facilitating the improvement of the stability of the movement of the adjustment block 22.

[0040] In addition, in specific applications, the longitudinal sections of the two sliders 26 are both in the shape of an I, which facilitates sliding engagement with the rectangular groove, thereby improving the stability of the detection tooling 24 in detecting sofa fabrics.

[0041] In one embodiment, for the above-mentioned retraction component 3, the retraction component 3 includes eight fixed rods 31, eight blocks 33 and eight slots 35, wherein four of the fixed rods 31 are symmetrically arranged on one side of the two vertical plates 4, and the other four fixed rods 31 are symmetrically arranged on one side of the two support plates 7, each two of the fixed rods 31 are slidably connected to the surface of a splint 32, each two of the blocks 33 are respectively arranged on one side of each of the splints 32, and a retraction spring 34 is sleeved on the outer side of each fixed rod 31, and the eight slots 35 are all opened on the inner side of the placement table 6, so that the stability of the contact between the splint 32 and the placement table 6 can be improved by corresponding to the blocks 33 through the slots 35.

[0042] In one embodiment, for the above-mentioned contraction springs 34, the two ends of four of the contraction springs 34 are respectively connected to the surface of the placement table 6 and one side of the two vertical plates 4, and the two ends of the other four contraction springs 34 are respectively connected to the surface of the placement table 6 and one side of the two support plates 7, and each of the clamping blocks 33 corresponds to each of the clamping slots 35, thereby facilitating the clamping of the clamping block 33 with the clamping slot 35.

[0043] In summary, with the help of the above technical solution of the present invention, the detection method of the first detection tool 24 is grinding, and the grinding disc is driven by the driving motor to rotate and contact the sofa fabric to grind it, so that the staff can identify whether the sofa fabric is pilling with their naked eyes to obtain the result of the wear resistance test. Then, the sofa fabric to be tested for wear resistance is placed on the placement table 6, and then the two opposite plywood 32 are first pushed outward. At this time, the two sides of the sofa fabric are tucked into the sides of the placement table 6, and then the two plywood 32 are loosened. 2. Then, under the elastic retraction action of the corresponding contraction spring 34, the two clamps 32 will press the two sides of the sofa fabric against the placement table 6 to limit the position. Then repeat the previous operation, push the other two clamps 32 outward, and then tuck the other two sides of the sofa fabric against the sides of the placement table 6. Then, release the two clamps 32, and the elastic retraction action of the other two contraction springs 34 will press the sides of the sofa fabric against the position to prevent the sofa fabric from shifting when the wear resistance test of the sofa fabric is carried out. In this case, the connecting screw 21 is driven to rotate by the second driving source 5. When the connecting screw 21 rotates, the adjusting block 22 threadedly connected thereto is driven to translate to the left at this time. Then, the detection tooling 24 is driven downward by the first driving source 23 to polish the sofa fabric, thereby performing a wear resistance test on the sofa fabric below. Then, when it is necessary to change the polishing position to test the wear resistance of the sofa fabric again, the adjusting block 22 is continued to be driven to the left by the connecting screw 21, or it can be moved to the right. Here, the left movement is described. At this time, the detection tooling 24 is driven to move to the left as a whole to perform a wear resistance test on different positions of the sofa fabric. Performing a wear resistance test on multiple locations of the sofa fabric helps to improve the effect of the sofa fabric test. When the adjusting block 22 moves left or right, the two sliders 26 slide inside the rectangular grooves opened in the two limit plates 27, thereby providing support force for the adjusting block 22, thereby improving the stability of the movement of the adjusting block 22 and preventing the adjusting block 22 from shaking or being unstable when the wear resistance test of the sofa fabric is performed. The operation is simple and convenient.

[0044] Through the above technical solution, 1. the adjusting block 22 is driven to move horizontally to the left or right by connecting the screw rod 21, and the detection tooling 24 is controlled to move up and down by the first driving source 23, so that it is easy to fit with the sofa fabric and thus perform wear resistance testing on the sofa fabric. The two sliders 26 sliding inside the rectangular groove provide a stable supporting force for the sides of the adjusting block 22, thereby improving the stability of the movement of the adjusting block 22 and preventing the adjusting block 22 from shaking or being unstable when the sofa fabric is subjected to wear resistance testing; 2. the elastic contraction of the contraction spring 34 drives the splint 32 to move and cooperate with the placement table 6 to tightly fix the sofa fabric, which is conducive to the wear resistance testing of the sofa fabric and prevents the sofa fabric from shifting during the test. The engagement of the clamping block 33 with the clamping slot 35 further improves the stability of the splint 32 in limiting the position of the sofa fabric.
