Description

Technical Field

[0001] The present invention relates to the field of carpet detection, and particularly to a device for testing the tensile strength of a carpet. Background Art

[0002] In the fields of carpet production and quality inspection, the tensile strength of a carpet is one of the important indicators to measure its quality. Accurately and efficiently testing the tensile strength of a carpet is crucial for ensuring product quality and optimizing the production process.

[0003] Currently, the traditional device for testing the tensile strength of a carpet has obvious deficiencies during operation. When conducting a test, the operator usually needs to first limit and fix one side of the carpet. After completing the unilateral limitation, the operator still needs to manually straighten the carpet to make it in a suitable test state, and then limit the other side and carry out the detection. This process is not only cumbersome, increasing the workload of the operator, but also resulting in low overall operation efficiency and extended detection time. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a device for testing the tensile strength of a carpet. The limiting part of the device is arranged in the up-down direction. After the upper part is limited, the carpet is in a straightened state under the action of gravity, and then the lower part can be limited for detection. By using this method, the step of the operator straightening the carpet after completing the unilateral limitation is omitted, improving the overall operation efficiency, and also simulating the detection under different environments.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The refrigerating end of the semiconductor refrigerating sheet extends into the temperature adjusting box. A plurality of electric heating wires are installed on the front and rear sides of the temperature adjusting box.

[0011] Preferably, a circulating fan is installed on the right side of the housing. The air outlet end of the circulating fan is communicated with a hose. The other end of the hose is connected to the looped hollow strip. The air inlet end of the circulating fan is communicated with the inner bottom of the temperature adjusting box. The inner top space of the temperature adjusting box is communicated with the inner top space of the housing through a ventilation connecting pipe.

[0012] Preferably, a mounting frame is fixedly connected to the upper end of the housing. A driving motor is installed on the mounting frame.

Guide blocks 27 are fixedly connected to both sides of each adjusting plate 26, and each guide block 27 extends into the corresponding guide groove 28 and is slidably connected thereto;

[0028] As an embodiment of the present invention, it further comprises a temperature adjustment mechanism. The temperature adjustment mechanism is used to simulate detections under different environments. The temperature adjustment mechanism includes a return-shaped hollow strip 17 provided inside the detection groove 14. A plurality of air injection holes 21 are provided on the left and right inner side walls of the return-shaped hollow strip 17. A temperature adjustment box 4 is fixedly connected to the right side of the housing 1. A semiconductor refrigeration sheet 5 is installed on the right side of the temperature adjustment box 4. A heat dissipation fan is also installed at the hot end of the semiconductor refrigeration sheet 5 to achieve heat dissipation of the semiconductor refrigeration sheet 5. The refrigeration end of the semiconductor refrigeration sheet 5 extends into the temperature adjustment box 4. A plurality of heating wires 24 are installed on the front and rear sides of the temperature adjustment box 4. A circulation fan 7 is installed on the right side of the housing 1. The air outlet end of the circulation fan 7 is communicated with a hose 8. The other end of the hose 8 is connected to the return-shaped hollow strip 17. The air inlet end of the circulation fan 7 is communicated with the inner bottom of the temperature adjustment box 4. The inner top space of the temperature adjustment box 4 is communicated with the inner top space of the housing 1 through a ventilation connecting pipe 6;

[0029] As an embodiment of the present invention, an installation frame 9 is fixedly connected to the upper end of the housing 1. A drive motor 10 is installed on the installation frame 9. The output shaft of the drive motor 10 extends into the detection groove 14 and is fixedly connected to a reciprocating lead screw 15. A slider 16 is threadedly connected to the reciprocating lead screw 15. The left side of the slider 16 is in contact with and slidably connected to the left inner wall of the detection groove 14. The right side of the slider 16 is fixedly connected to a loop-shaped hollow strip 17. A connecting cylinder 18 is installed at the inner top of the detection groove 14. Two air inlets 19 are provided in the inner top space of the connecting cylinder 18. A rotating shaft 13 is rotatably connected to the inner top of the connecting cylinder 18. A plurality of axial flow fan blades 20 are installed at the lower end of the rotating shaft 13. The upper end of the rotating shaft 13 extends to the outside. Pulley 11 is installed on both the rotating shaft 13 and the drive motor 10. The two pulleys 11 are connected by a transmission belt 12. Through this structure, the detection of the device in high-temperature or low-temperature environments can be realized.

[0030] In the present invention, in the test preparation stage, the sealing door 3 is opened, and the carpet sample to be tested is placed in the loop-shaped frame 23 in the test mechanism. By controlling the hydraulic telescopic rods 25 at the inner top and inner bottom of the loop-shaped frame 23, the telescopic ends drive the adjusting plate 26 to move. Since the guiding blocks 27 on both sides of the adjusting plate 26 are slidably connected in the guiding grooves 28 on the left and right side walls of the loop-shaped frame 23, the stability of the movement of the adjusting plate 26 is ensured. The threaded rod 32 on the first fixing plate 31 is rotated. Since the threaded rod 32 is threadedly connected to the first fixing plate 31, and the clamping plate 30 rotatably connected to the rear side of the threaded rod 32 is in contact with and slidably connected to the adjusting plate 26, rotating the threaded rod 32 can move the clamping plate 30. Then, the two ends of the carpet sample are fixed to the adjusting plate 26 by using the second fixing plate 29 and the clamping plate 30, completing the installation of the carpet sample. During specific operation, after the upper part of the limit is completed, at this time, the carpet is straightened under the action of gravity. At this time, the lower limit can be carried out for detection. By using this method, the step of the operator straightening the carpet after completing the unilateral limit is omitted, improving the overall operation efficiency.

[0031] Subsequently, two hydraulic telescopic rods 25 are activated to contract for detection. After each single detection is completed, the semiconductor refrigeration chip 5 can be activated. Its refrigerating end generates cold in the temperature regulation box 4, cooling the air in the temperature regulation box 4. At the same time, the heat dissipation fan at the hot end of the semiconductor refrigeration chip 5 is started to dissipate heat from the semiconductor refrigeration chip 5 to ensure its normal operation. The circulation fan 7 is started, and the air with adjusted temperature in the temperature regulation box 4 is transported through the hose 8 into the loop-shaped hollow strip 17. The air is ejected from multiple air ejection holes 21 on the inner walls of the left and right sides of the loop-shaped hollow strip 17 to regulate the temperature of the surrounding environment of the carpet sample in the detection groove 14. After the ejected air circulates in the detection groove 14, it returns to the temperature regulation box 4 again through the ventilation connecting pipe 6 to form an air circulation, making the temperature in the detection groove 14 uniform and completing the low-temperature detection. If it is necessary to simulate a high-temperature environment, the heating wires 24 on the front and rear sides of the temperature regulation box 4 are activated (and the semiconductor refrigeration chip 5 is turned off). The heating wires 24 generate heat to increase the temperature of the air in the temperature regulation box 4, and the circulation fan 7 is activated to carry out the detection under a high-temperature environment;

[0032] During the process of simulating temperature detection, the drive motor 10 on the mounting frame 9 can also be activated. The output shaft of the drive motor 10 drives the reciprocating lead screw 15 to rotate. Since the slider 16 is threadedly connected to the reciprocating lead screw 15, and the left side of the slider 16 is in contact with and slidably connected to the left inner wall of the detection groove 14, when the reciprocating lead screw 15 rotates, the slider 16 will move up and down along the reciprocating lead screw 15. The right side of the slider 16 is fixedly connected to the loop-shaped hollow strip 17. Therefore, when the slider 16 moves, it will drive the loop-shaped hollow strip 17, making the temperature-controlled gas ejected by it cover the detection groove 14 more evenly and further improving the internal temperature uniformity;

[0033] While the drive motor 10 is working, the pulley 11 on the output shaft of the drive motor 10 drives the pulley 11 on the rotating shaft 13 to rotate through the transmission belt 12, thereby causing the rotating shaft 13 to rotate at the top of the connecting cylinder 18. The multiple axial flow fan blades 20 at the lower end of the rotating shaft 13 rotate accordingly. The airflow generated by the rotation of the axial flow fan blades 20 enters from the two air inlets 19 in the top space of the connecting cylinder 18, which helps the air circulation in the detection groove 14 and makes the temperature uniformity extremely good, ensuring the detection effect;

[0034] After the tensile strength test is completed, the drive motor 10, the circulation fan 7, the semiconductor refrigeration chip 5 (if in the refrigeration mode), and the heating wires 24 (if in the heating mode) are turned off.

[0035] Open the sealing door 3, reverse-rotate the threaded rod 32 to release the clamping plate 30 from the carpet sample, remove the tested carpet sample, and clean the detection groove 14 to prepare for the next test.
