Description

Technical Field

[0001] The invention relates to the technical field of carpet testing, in particular to a carpet strength production and preparation testing device. Background Art

[0002] Carpets are floor coverings made of natural fibers such as cotton, linen, wool, silk, grass, or chemical synthetic fibers, which are knitted, flocked, or woven by hand or mechanical processes. They have the effects of reducing noise, heat insulation, and decoration. In order to ensure the service life of carpets, it is usually necessary to conduct strength tests on them after they are manufactured.

[0003] However, there are usually some problems in the daily use of ordinary carpet strength production and preparation test devices. With the development of science and technology, technicians in related fields have also made a lot of optimizations on carpet strength production and preparation test devices to solve some problems that different consumer groups care about. In order to make a more accurate comparison, such as the publication number CN219179095U

[0004] The Chinese patent discloses a carpet strength testing device; when in use, the device uses a test bench and a testing mechanism on the test bench, the testing mechanism includes a stretching assembly and a fixing assembly, and drives the fixed motor to drive the screw to operate, so that the two movable seats are separated from each other, and the carpet can be horizontally stretched to test the strength of the carpet when it is horizontally stretched. Driving the two movable motors to operate can drive the two ends of the carpet to flip respectively, so as to test the strength of the carpet when it is stretched in different directions, making the test of the carpet strength more rigorous and the test results more referenceable.

[0005] However, the above-mentioned carpet strength testing device still has some shortcomings in actual use: 1. The above-mentioned prior art can perform a tensile test on the carpet, and a reversible mechanism is provided to achieve the strength of the carpet when the stretching angle is different. However, in the actual test process, it is usually necessary to perform a wear resistance test on the carpet in different directions and at different angles to ensure that the carpet can still have a long service life and a good use experience after being stretched and stepped on to different degrees during actual use.

[0006] Although the above-mentioned prior art can realize tensile testing of the carpet at different angles by flipping the corresponding structure, during the flipping process, the flipping direction and angle are fixed, and it cannot be guaranteed that the carpet can be subsequently tensile tested in different directions and angles, which is not conducive to improving the accuracy of testing the strength of the carpet.

[0007] Therefore, under the above-stated viewpoints, there is still room for improvement in the existing carpet strength production and preparation testing equipment. Summary of the invention

[0052] Reference Figure 2 As shown, the conveying and cutting mechanism 3 is used to cut the carpet and convey it to the stretching mechanism 4; specifically, the conveying and cutting mechanism 3 includes a conveyor belt 30, a supporting side plate 31, a cutting knife 32 and a control rod 33. A conveyor belt 30 is provided on one side of the upper end of the workbench 1. The conveyor belt 30 is an inclined structure. The conveyor belt 30 is used to convey the carpet after production and processing to the stretching mechanism 4. Two supporting side plates 31 are provided on the side of the conveyor belt 30 close to the friction mechanism 2. A cutting knife 32 is provided between the two supporting side plates 31 through a torsion spring. The supporting side plate 31 is used to support and fix the cutting knife 32. The cutting knife 32 is used to cut the carpet into the size required by the sample to be tested. The cutting knife 32 is provided at one end away from the supporting side plate 31. The control rod 33 is convenient for controlling the cutting knife 32 to ensure smooth cutting of the carpet.

[0057] During operation, the driving cylinder three 49 pushes the moving block 43 to the rightmost end of the sliding groove 40 so that the conveying and cutting mechanism 3 can smoothly convey the carpet to the top of the moving block 43. Then, the clamping block 44 clamps the two ends of the carpet in the clamping groove 45. The driving cylinder three 49 drives the tension spring 48 to move to the left, and then the tension spring 48 drives the moving block 43 to move to the left, thereby realizing the tension test of the carpet.

The driving cylinder four 51 is symmetrically arranged on the front and rear sides of the support frame 50. The support frame 50 is used for installing and fixing the driving cylinder four 51. The telescopic ends of the two driving cylinders four 51 are jointly provided with a fixing frame 52 in a C-shaped structure. The driving cylinder four 51 is used to drive the fixing frame 52 to move up or down.

[0069] The middle of the horizontal section of the fixing frame 52 is rotatably provided with a rotating disk 53. The lower end of the rotating disk 53 is provided with a rotating rod 54. The end of the rotating rod 54背离 the rotating disk 53 is provided with a driving gear 55. The rotating rod 54 is used for installing and fixing the driving gear 55. The driving cylinder five 56 is arranged on the lower horizontal section of the fixing frame 52. The telescopic end of the driving cylinder five 56 is provided with a driving rack 57 engaged with the driving gear 55, and the driving rack 57 is slidably connected to the lower horizontal section of the fixing frame 52. The driving cylinder five 56 is used to drive the driving rack 57 to reciprocate horizontally in the fixing frame 52. The mutual cooperation of the driving rack 57 and the driving gear 55 can drive the rotating rod 54 to rotate, and then the rotating rod 54 drives the rotating disk 53 to rotate, so as to ensure that the carpet can rotate smoothly by a certain angle, so as to perform tensile tests and wear resistance tests on the carpet at different angles.

[0070] The upper end of the rotating disk 53 is also provided with a supporting unit 58, and the supporting unit 58 is used for supporting the carpet to prevent the carpet from falling down during conveying or rotating.

[0071] Referring to Fig. 9 It should be noted that there is an unclear expression "背离" in the original text. I have translated it as "背离" for now, but it may need to be further clarified according to the specific context.As shown, a supporting unit 58 is used to support the carpet; specifically, the supporting unit 58 includes a rotating plate 580, a rectangular groove 581, a supporting plate 582, a bidirectional electric push rod 583 and a supporting extension plate 584. The upper end of the rotating disk 53 is provided with a rotating plate 580, and rectangular grooves 581 are symmetrically provided on both sides of the rotating plate 580, and the direction of the rectangular grooves 581 is parallel to the direction of the installation side plate 20. A supporting plate 582 is provided in the rectangular groove 581, and the supporting plate 582 is a hollow structure. The rotating plate 580 is used to drive the supporting plate 582 to rotate and play a certain supporting role on the carpet. The rectangular groove 581 is used to extend the supporting plate 582 The supporting plate 582 is provided with a two-way electric push rod 583 inside, and the two telescopic ends of the two-way electric push rod 583 are provided with a supporting extension plate 584, and the supporting extension plate 584 is slidably arranged in the supporting plate 582. The supporting plate 582 and the supporting extension plate 584 are both used to support the carpet. The two-way electric push rod 583 is used to drive the supporting extension plate 584 to extend and contract to prevent the carpet from falling downward due to its own gravity around it during rotation, thereby ensuring that after the carpet is rotated to a certain angle, the stretching mechanism 4 can still resume the clamping and fixing of the two ends of the carpet, so as to ensure that the carpet can be smoothly subjected to tensile tests and wear tests at different angles.

[0072] During operation, first, the bidirectional electric push rod 583 retracts the supporting extension plate 584 into the supporting plate 582, and after the lifting and rotating mechanism 5 drives the supporting unit 58 to move upward to a certain height, the bidirectional electric push rod 583 extends the supporting extension plate 584 along the rectangular groove 581, so that the carpet can smoothly pass through the supporting unit 58 and be transported to the moving block 43, and the stretching mechanism 4 clamps and fixes the two ends of the carpet, and then the supporting extension plate 584 retracts into the supporting plate 582, and the lifting and rotating mechanism 5 drives the supporting unit 58 to move downward to a certain height to avoid affecting the tensile test and the wear test. After completing a tensile test and After the wear test, the lifting and rotating mechanism 5 drives the supporting unit 58 to move upward to a certain height, and the stretching mechanism 4 releases the clamping of the two ends of the carpet, so that the carpet falls flat on the supporting unit 58, and then the lifting and rotating mechanism 5 drives the supporting unit 58 to rotate a certain angle. At this time, the supporting extension plate 584 extends along the rectangular groove 581 to keep the carpet in a horizontal state all around, and then the stretching mechanism 4 restores the fixed clamping of the two ends of the carpet, and the supporting extension plate 584 is retracted into the supporting plate 582. The lifting and rotating mechanism 5 drives the supporting unit 58 to move downward to ensure that the carpet can be smoothly subjected to tensile tests and wear tests at different angles.

[0073] Reference Fig.10As shown, a corrugated rail 60 is provided on the corrugated surface in the middle of the corrugated block 292, and a sliding ball 61 located in the corrugated rail 60 is provided at one end of the adjusting rod 293 close to the corrugated block 292. The corrugated rail 60 is used to guide and limit the sliding ball 61, so that the sliding ball 61 can slide in the corrugated rail 60 along with the ups and downs of the corrugated block 292, and then with the cooperation of the pressing plate 295, the adjusting ring 26 can slide back and forth between the two mounting side plates 20, so as to rub the carpet in different directions and at different positions, so as to ensure that the carpet is fully tested for wear resistance.

[0074] Reference Fig.10 As shown, the two movable through slots 21 located on the same mounting side plate 20 are on opposite sides and close to one end of the conveying and cutting mechanism 3, and the movable slot 1 70 is provided. The movable slot 1 70 allows the pin shaft 23 and the rotating rod 22 to move upward or downward. Before the tensile test, the bidirectional cylinder 281 drives the linear rack 282 and the rotating gear 283 to move upward or downward, thereby driving the pin shaft 23 and the rotating rod 22 to move upward or downward, so that a certain gap is left between the rotating rods 22 on the upper and lower sides, so that the carpet can pass through the friction rod 27 and be smoothly transported to the moving block 43, so as to ensure that the stretching mechanism 4 can clamp and fix the two ends of the carpet, so as to ensure that the subsequent tensile test and wear test of the carpet can be carried out smoothly. The two corrugated slide rails 60 located on the same mounting side plate 20 are on opposite sides and close to one end of the conveying and cutting mechanism 3, and the movable slot 2 71 is provided. The movable slot 2 71 allows the adjusting rod 293 to move upward or downward, so as to avoid the adjusting rod 293 interfering with the upward or downward movement of the pin shaft 23 and the rotating rod 22.

[0075] In addition, the present invention also provides a carpet strength production preparation test method, comprising the following steps: S1: carpet stretching test: first, the carpet after production and processing is placed on the conveying and cutting mechanism 3, and the size of the tested carpet is controlled by manipulating the conveying and cutting mechanism 3. When the carpet is supported by the lifting and rotating mechanism 5 and the supporting unit 58 and smoothly transported to the stretching mechanism 4, the stretching mechanism 4 clamps the two ends of the carpet so that the stretching mechanism 4 can smoothly perform a stretching test on the carpet.

[0076] S2: Carpet wear test: After the carpet has completed the stretching test, both ends of the carpet are still fixed by the stretching mechanism 4, and the friction mechanism 2 performs a wear test on both sides of the carpet. Through the cooperation of the rotating unit 28 and the sliding unit 29, the carpet can be further rubbed at different positions and angles, so that the friction mechanism 2 can smoothly perform a wear test on the carpet.

[0077] S3: Rotational support adjustment: After the carpet has completed the tensile test and the wear test, it is necessary to perform tensile tests and wear tests at different angles on the carpet. The lifting and rotating mechanism 5 and the supporting unit 58 support the carpet, and the stretching mechanism 4 releases the clamping angle of the carpet so that the lifting and rotating mechanism 5 can drive the carpet to rotate, and the clamping angle of the carpet by the stretching mechanism 4 is adjusted, so that the stretching mechanism 4 and the friction mechanism 2 can perform tensile tests and wear tests at different angles on the carpet.
