Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0019] Please refer to Figures 1-5 The utility model provides a kind of high temperature test chamber for PTFE film-coated felt production:

[0020] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , Figure 5 It includes test chamber 1, test chamber 1 inside fixed installation has the article table 2, test chamber 1 inside both sides fixed installation has electric telescopic link one 3, the port of electric telescopic link one 3 fixed installation has clamp 4, clamp 4 is placed on article table 2, the side of clamp 4 is equipped with motor one 5, the rotating end of motor one 5 is connected with rotating rod, and the rotating rod is arranged in the inside of clamp 4, and clamp 4 is closed by rotating rod, the bottom side of test chamber 1 is fixedly installed with electric telescopic link two 6, and the top of electric telescopic link two 6 is fixedly installed with motor two 7, and the rotating end of motor two 7 is connected with electric telescopic link three 8, and the port of electric telescopic link three 8 is fixedly installed with motor three 9, and the rotating end of motor three 9 is connected with rotating shaft, and the one side of rotating shaft is fixedly installed with sandpaper table 11, and the connecting place of sandpaper table 11 and motor three 9 is equipped with shaft coupling 10, and the bottom both sides of sandpaper table 11 are all provided with slot and threaded hole, and the slot is equipped with clamping plate 12, and the side of clamping plate 12 is fixedly installed with bolt, and the bolt is connected with threaded hole in screw thread.

[0021] The bottom of test chamber 1 is fixedly installed with heating oven 13, and heating pipe 14 is fixedly installed in heating oven 13.

[0022] The side of test chamber 1 is fixedly installed with power supply 19, and the side of test chamber 1 is fixedly installed with control panel 20.

[0023] The power supply 19 is electrically connected with electric telescopic link one 3, motor one 5, electric telescopic link two 6, motor two 7, electric telescopic link three 8, motor three 9, clamping plate 12, heating pipe 14 and control panel 20, and the control panel 20 is signal connected with electric telescopic link one 3, motor one 5, electric telescopic link two 6, motor two 7, electric telescopic link three 8, motor three 9, clamping plate 12 and heating pipe 14.

[0024] The material of the storage platform 2 is ceramic, which has excellent heat conduction effect.

[0025] The bottom of the sandpaper platform 11 is provided with replaceable sandpaper, which is clamped by the clamping plate 12.

[0026] The worker places the PTFE film on the lower clamp of the clamp 4, and then turns on the heating pipe 14 through the control panel 20 to heat the test box 1. After heating to the appropriate test temperature, the worker controls the motor 5 to operate through the control panel 20, so that the upper and lower clamps of the clamp 4 are closed to clamp the PTFE film. When the PTFE film reaches the test temperature, the worker controls the two electric telescopic rods 3 to move through the control panel 20, and then controls the electric telescopic rod 8 to stretch out above the PTFE film through the control panel 20, and then makes the electric telescopic rod 6 shrink to adhere to the PTFE film. Finally, the motor 9 is rotated to rotate the sandpaper platform 11 to perform the friction test on the PTFE film. The coupling 10 can make the sandpaper platform 11 rotate without shaking due to centrifugal force, which affects the test.

[0027] When the sandpaper at the bottom of the sandpaper platform 11 needs to be replaced, the worker makes the electric telescopic rod 6 stretch out through the control panel 20, so that the sandpaper platform 11 moves away from the storage platform 2, and then controls the electric telescopic rod 8 to rotate 180° through the motor 7, so that the sandpaper platform 11 rotates 180°. Then, the worker removes the used sandpaper by widening the gap between the clamping plate 12 and the slot through the bolt, and then places the new sandpaper at the bottom of the sandpaper platform 11 (at this time, the bottom of the sandpaper platform 11 has been turned over to the top). The worker places the two sides of the sandpaper in the slot of the sandpaper platform 11, and then narrows the gap between the clamping plate and the slot through the bolt until the two sides of the sandpaper are clamped, so that the sandpaper is tightly attached to the bottom of the sandpaper platform 11. Then, the worker controls the electric telescopic rod 8 to rotate 180° through the motor 7, so that the sandpaper platform 11 returns to the original position.

[0028] Referring to Figure 1 , Figure 4 , the top of the test box 1 is provided with a test cover 15, and the connection between the test cover 15 and the test box 1 is rotatably connected with a hinge 16.

[0029] The top of the test cover 15 is fixedly installed with a handle 17, and the four corners of the test box 1 are fixedly installed with a bottom foot 18.

[0030] The test cover 15 is a transparent cover, which is convenient for the worker to observe the test

[0031] The worker can open the test cover 15 through the handle 17, and can replace the PTFE film or perform the test by hand. The bottom foot 18 increases the stability of the test box, so as to avoid shaking of the test box during the friction test and affect the test data.

[0032] Working principle: the staff puts the PTFE film on the lower clamp of clamp 4, opens the heating tube 14, heats the test box 1, closes the upper and lower clamps of clamp 4 after heating to the appropriate test temperature, clamps the PTFE film, waits for the PTFE film to reach the test temperature, controls the movement of the electric telescopic rod 3 on both sides, stretches the PTFE film, and then adjusts the sandpaper table 11 to the appropriate position to conduct the friction test of the PTFE film.

[0033] When the sandpaper at the bottom of the sandpaper table 11 needs to be replaced, the staff controls the electric telescopic rod 6 to extend through the control panel 20, makes the sandpaper table 11 away from the workbench 2, then controls the motor 7 to make the electric telescopic rod 8 rotate 180°, and then makes the sandpaper table 11 rotate 180°, then expands the distance between the bolt expansion clamp 12 and the slot, removes the used sandpaper, then places the new sandpaper at the bottom of the sandpaper table 11 (at this time the bottom of the sandpaper table 11 has been turned to the top), places the two sides of the sandpaper in the slot of the sandpaper table 11, reduces the distance between the bolt clamp and the slot, until the two sides of the sandpaper are clamped, so that the sandpaper is tightly attached to the bottom of the sandpaper table 11, then controls the motor 7 to make the electric telescopic rod 8 rotate 180°, and then makes the sandpaper table 11 return to the original position.

[0034] The staff can open the test cover 15 through the handle 17, replace the PTFE film, or conduct the test.
