Description

Technical Field

[0001] This utility model relates to the technical field of fabric testing equipment, and in particular to a high-efficiency fabric adhesion tester. Background Technology

[0002] When clothes are worn, they become soaked as the body sweats. Some materials even stick to the skin. Therefore, among the many tests required for clothing fabrics is the fabric adhesion test. The specific test method involves stretching the fabric and attaching it to a sweating board to simulate sweating. Stress sensors are placed on the sweating board, and then the fabric is moved longitudinally and tangentially. The measured data is collected and recorded for calculating the fabric adhesion rate. To make the entire testing process more accurate and efficient, it is urgent to design a device that can automatically control the fabric during the test. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this invention provides a high-efficiency fabric adhesion tester, comprising a test chamber with a door and an automatic testing device. The automatic testing device is housed within the test chamber and includes a control system, a digital display, a sweat-generating plate assembly for simulating human sweating, a mounting frame, a pair of force sensors for measuring force in different directions, a mounting clamp for fabric installation, a limiting mechanism, a connecting block, a longitudinal movement mechanism for controlling fabric movement, and a tangential movement mechanism. The longitudinal movement mechanism is connected to the inner wall of the test chamber, the tangential movement mechanism is connected to the longitudinal movement mechanism, the mounting clamp is connected to the tangential movement mechanism via the connecting block, the limiting mechanism is mounted on the mounting clamp, the mounting frame is fixedly mounted on the bottom surface inside the test chamber, the sweat-generating plate assembly is mounted on the mounting frame, the pair of force sensors are connected to the sweat-generating plate assembly, and the digital display is located on the outside of the test chamber. The control system is connected to the force sensors, the longitudinal movement mechanism, the tangential movement mechanism, and the digital display.

[0004] Using the above technical solution, when conducting fabric adhesion force testing, the fabric to be tested is simply placed on the mounting plate and clamped by the limiting device, so that the fabric is taut and flat on the mounting plate. Then, the equipment is started, and the longitudinal movement mechanism controls the taut fabric to move towards the sweating plate group. After the fabric adheres to the surface of the sweating plate group and is wetted by the simulated sweat seeping from the sweating plate group, it continues to move. At this time, the force sensor connected to the sweating plate group can measure the longitudinal adhesion force. Then, the tangential movement mechanism controls the fabric to move tangentially on the sweating plate group. At this time, the force sensor connected to the sweating plate group can measure the tangential adhesion force. After the test is completed, the individual and comprehensive forces will be displayed on the digital display panel. The entire test process is automatic except for the fabric installation, which improves the experimental efficiency and makes the measured data more accurate.

[0005] Further features of this invention: The mounting clamp includes a back plate, a pair of fixed support blocks for keeping the fabric away from the back plate, and a pair of clamping blocks. The pair of fixed support blocks are symmetrically arranged on both sides of the back plate. The pair of clamping blocks are detachably connected to the fixed support blocks through a limiting mechanism. The limiting mechanism includes several connecting pins with external threads and several wing nuts. The pair of fixed support blocks and the pair of clamping blocks are provided with notches for installing the connecting pins. The connecting pins are disposed in the notches of the fixed support blocks and are rotatably connected to the notches.

The pair of fixed support blocks are symmetrically arranged on both sides of the back plate. The pair of clamping blocks are detachably connected to the fixed support blocks through a limiting mechanism. The limiting mechanism includes several connecting pins with external threads and several wing nuts. Both the pair of fixed support blocks and the pair of clamping blocks have notches for installing the connecting pins. The connecting pins are set in the notches of the fixed support blocks and rotated to connect with the notches. When installing the fabric material, simply place the fabric on the pair of fixed support blocks and spread it out, press the pair of clamping blocks on the fabric, rotate the pair of connecting pins so that they are in the notches, then fine-tune the fabric to make it nearly taut and flat, and then tighten the wing nuts to make the fabric fully taut, thus completing the limiting and fixing of the fabric.

[0007] A further feature of this invention is that the back plate has a connecting groove that matches the connecting block, and a threaded hole is provided on the side wall of the connecting groove, with a limiting screw inside the threaded hole.

[0008] By adopting the above technical solution, since the back plate has a connecting groove that matches the connecting block, and the side wall of the connecting groove has a threaded hole with a limiting screw inside the threaded hole, when installing the fabric material, the installation clamp can be removed first and placed on a table or other flat surface for the installation of the material. After the installation is completed, the installation clamp can be put back on the tangential moving mechanism, making the installation of the material more convenient.

[0009] A further feature of this invention is that the surfaces on which the pair of fixed support blocks and the pair of clamping blocks fit together are provided with several anti-slip protrusions that engage with each other.

[0010] By adopting the above technical solution, since the surfaces of the pair of fixed support blocks and the pair of clamping blocks that are in contact with each other are provided with several anti-slip protrusions that engage with each other, the limiting of the material cloth is more secure and stable.

[0016] When conducting the fabric adhesion test, simply place the fabric to be tested 24 on the mounting plate and clamp it with the limiting device to make the fabric taut and flat on the mounting plate. Then start the equipment, and control the taut fabric to move towards the sweating plate group through the longitudinal movement mechanism. After the fabric adheres to the surface of the sweating plate group and is wetted by the simulated sweat seeping from the sweating plate group, it continues to move. At this time, the force sensor connected to the sweating plate group can measure the longitudinal adhesion force. Then, the tangential movement mechanism controls the fabric to move tangentially on the sweating plate group. At this time, the force sensor connected to the sweating plate group can measure the tangential adhesion force. After the test is completed, the individual and comprehensive forces will be displayed on the digital display panel. The entire test process is automatic except for the fabric installation, which improves the experimental efficiency and makes the measured data more accurate.

The limiting mechanism includes several connecting pins 17 with external threads and several wing nuts 18. The pair of fixed support blocks and the pair of clamping blocks are provided with notches 19 for installing the connecting pins. The connecting pins are set in the notches of the fixed support blocks and are rotatably connected to the notches.

[0018] The mounting plate includes a back plate, a pair of fixed support blocks for keeping the fabric away from the back plate, and a pair of clamping blocks. The pair of fixed support blocks are symmetrically arranged on both sides of the back plate. The pair of clamping blocks are detachably connected to the fixed support blocks through a limiting mechanism. The limiting mechanism includes several connecting pins with external threads and several wing nuts. Both the pair of fixed support blocks and the pair of clamping blocks have notches for installing the connecting pins. The connecting pins are set in the notches of the fixed support blocks and rotated to connect with the notches. When installing the fabric material, simply place the fabric on the pair of fixed support blocks and spread it out, press the pair of clamping blocks on the fabric, rotate the pair of connecting pins to position them in the notches, then fine-tune the fabric to make it nearly taut and flat, and then tighten the wing nuts to fully tension the fabric, thus completing the limiting and fixing of the fabric.

[0019] The back plate has a connecting groove 20 that matches the connecting block. A threaded hole 21 is opened on the side wall of the connecting groove, and a limiting screw 22 is provided in the threaded hole.

[0020] Since the back plate has a connecting groove that matches the connecting block, and a threaded hole is opened on the side wall of the connecting groove, and a limiting screw is provided in the threaded hole, when installing the fabric material, the installation clamp can be removed first and placed on a table or other flat surface for the installation of the material. After the installation is completed, the installation clamp can be put back on the tangential moving mechanism, making the installation of the material more convenient.

[0021] The surfaces on which the pair of fixed support blocks and the pair of clamping blocks fit together are provided with several anti-slip protrusions 23 that engage with each other.
