[0028] See also Figures 1-6 The present invention provides an embodiment of a PC film production toughness testing machine, comprising a testing platform 1, a fixed platform 3, and a movable platform 9. The fixed platform 3 is welded to one side of the top of the testing platform 1, and the movable platform 9 is provided on the other side of the top of the testing platform 1. A stretching mechanism 2 is provided inside the testing platform 1.

[0029] The stretching mechanism 2 includes an adjusting motor 201, and the adjusting motor 201 is arranged inside the detection platform 1. An adjusting rod 202 is fixed to one side of the adjusting motor 201, and an adjusting block 203 is sleeved on the outside of the adjusting rod 202. A driving bevel gear 204 is welded to one end of the adjusting rod 202, and a driven bevel gear 206 is meshed on one side of the driving bevel gear 204. A driven shaft 205 passes through the inside of the driven bevel gear 206, and the driven shaft 205 extends to the outside of the detection platform 1 and is sleeved with a movable block 208.

[0030] There are two support plates 209, and the cross section formed by the two support plates 209 and the stretching block 207 is U-shaped;

[0031] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 5As shown, when in use, the adjusting motor 201 is started to drive the adjusting rod 202 to rotate. On the one hand, the movable table 9 is driven to move horizontally under the action of the adjusting block 203, thereby stretching the PC film in the horizontal direction. On the other hand, the movable block 208 is driven to move upward under the action of the driving bevel gear 204, the driven bevel gear 206 and the driven shaft 205, thereby driving the stretching block 207 to move upward synchronously under the action of the support plate 209, thereby stretching the PC film in the vertical direction. The above operation facilitates multi-directional stretching of the PC film, thereby improving the practicality of its detection.

[0032] The top of the fixed platform 3 and the movable platform 9 are both welded with a support frame 10, the top of the support frame 10 is fixed with a hydraulic cylinder 8, and the bottom of the hydraulic cylinder 8 is fixed with a pressure plate 6, the bottom of the pressure plate 6 is provided with a slot 15, and the inside of the slot 15 is provided with a fixing block 14, and the inside of the fixing block 14 is provided with a limiting mechanism 13;

[0033] The limiting mechanism 13 includes a mounting groove 1302 disposed inside the fixing block 14 . A return spring 1303 is fixed inside the mounting groove 1302 . A baffle 1304 is disposed on one side of the return spring 1303 . A limiting block 1301 is fixed on one side of the baffle 1304 .

[0034] There are two groups of return springs 1303, each group of return springs 1303 is provided with two, and both groups of return springs 1303 are in a stretched state inside the mounting groove 1302;

[0035] The cross section of the baffle 1304 is circular, and the outer edge of the baffle 1304 is slidably fitted with the inner wall of the mounting groove 1302;

[0036] Specifically, such as Figure 4 、 Figure 6 As shown, when in use, the reset spring 1303 is reset to drive the limit block 1301 to move horizontally, thereby facilitating the fixing plate 5 to be fixed to the bottom end of the pressing plate 6, thereby facilitating the subsequent inspection of the PC film to prevent the PC film from sliding;

[0037] The bottom ends of the pressure plates 6 are all provided with fixing plates 5, and the bottom ends of the fixing plates 5 are all adhered with anti-sliding blocks 4;

[0038] There are multiple anti-sliding blocks 4, each of which has a semicircular cross-section and is made of rubber.

[0039] Specifically, such as Figure 1 、 Figure 4 As shown, when in use, the anti-sliding block 4 can prevent the PC film from moving in position, thereby affecting the detected data;

[0040] A guide groove 11 is provided on one side of the top of the testing platform 1, and a guide block 16 is slidably provided inside the guide groove 11;

[0041] The guide block 16 slides inside the guide groove 11, and the movable platform 9 is slidably connected to the detection platform 1 through the guide block 16 and the guide groove 11;

[0042] Guide rods 7 are welded to both the front and rear sides of the test platform 1, and scale lines 12 are provided on one side of the test platform 1 and the guide rods 7;

[0043] Specifically, such as Figure 2 、 Figure 5 As shown, when in use, the guide block 16 slides inside the guide groove 11, so that the moving platform 9 can be limited and guided, thereby improving its stability during movement.

[0044] Working principle: When the present invention is in use, first, the fixing plate 5 is pushed so that the fixing block 14 is inserted into the interior of the slot 15. During the insertion process, the limiting block 1301 is pressed to push the baffle 1304 to move horizontally. While the baffle 1304 moves horizontally, the return spring 1303 is squeezed, so that the return spring 1303 is compressed by the squeezing force, and then the limiting block 1301 is retracted into the interior of the installation slot 1302, until the fixing block 14 and the slot 15 are fitted together, so that the force on the return spring 1303 is eliminated. When the baffle 1304 is lost, the baffle 1304 is pushed to move horizontally. When the baffle 1304 moves horizontally, the limit block 1301 is driven to move horizontally synchronously until the limit block 1301 passes through the pressure plate 6, thereby limiting and fixing the fixing plate 5. The above operation facilitates fixing the anti-sliding block 4 to the bottom end of the pressure plate 6, thereby facilitating the subsequent limiting and fixing of the PC film, and preventing the PC film from loosening during toughness testing. In addition, when the anti-sliding block 4 is damaged, it can be removed and replaced, thereby achieving a durable effect.

[0045] Then, when the PC film is produced and needs to be tested for toughness, one side of the PC film is passed through between the fixed platform 3 and an anti-sliding block 4, and a hydraulic cylinder 8 is activated to drive the pressing plate 6 to move downward, and then drive the fixed plate 5 to move downward until an anti-sliding block 4 contacts one side of the PC film, thereby fixing one side of the PC film, and then the PC film is fixed. The other side of the film passes between the moving table 9 and the other anti-sliding block 4, and another hydraulic cylinder 8 fixes the other anti-sliding block 4 to the PC film under the action of the pressure plate 6 and the fixed plate 5, thereby starting the adjustment motor 201 to drive the adjustment rod 202 to rotate, and the adjustment rod 202 drives the adjustment block 203 to move horizontally while rotating, thereby driving the moving table 9 to make synchronous horizontal movement, and then making the guide block 16 slide inside the guide groove 11. By providing the guide groove 11, on the one hand, the moving moving table 9 can be limited to avoid positional deviation during the movement, thereby affecting subsequent operations, and on the other hand, the moving moving table 9 can be guided to improve its stability during movement. While the moving table 9 moves horizontally, it drives the PC film The film is stretched in the horizontal direction, and the adjusting rod 202 rotates and drives the driving bevel gear 204 to rotate synchronously on the other hand. Since the driving bevel gear 204 and the driven bevel gear 206 are engaged with each other, the driving bevel gear 204 rotates and drives the driven bevel gear 206 to rotate synchronously. When the driven bevel gear 206 rotates, it drives the driven shaft 205 to rotate synchronously, thereby driving the movable block 208 to move upward, and then drives the support plate 209 to move upward synchronously. When the support plate 209 moves upward, it drives the stretching block 207 to move upward synchronously under the action of the guide rod 7. The above operation facilitates the vertical stretching of the PC film, thereby improving the accuracy of the data when the PC film is tested for toughness.
