DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Figure 1-Figure 6 As shown, a stretching testing device for producing an antistatic stretch film includes a workbench 100, a fixed clamping mechanism 210, a movable clamping mechanism 220, two sets of pressing plate mechanisms 230 and a driving mechanism 300.

[0023] The fixed clamping mechanism 210 is fixedly installed on the top surface of the workbench 100; the movable clamping mechanism 220 is slidably installed on the top surface of the workbench 100; the two sets of pressure plate mechanisms 230 are respectively used to cooperate with the fixed clamping mechanism 210 and the movable clamping mechanism 220 to clamp the film 500; the driving mechanism 300 is used to drive the movable clamping mechanism 220 to move, and the driving mechanism 300 includes a vertical plate 301, a dynamometer 303 and a driving assembly.

[0024] The vertical plate 301 passes through the workbench 100 and is slidably connected to the workbench 100; the dynamometer 303 is installed on one side of the vertical plate 301, and the dynamometer 303 is connected to the movable clamping mechanism 220; the driving assembly is used to drive the vertical plate 301 to move.

[0025] Specifically, the film 500 that needs to be stretched is placed on the fixed clamping mechanism 210 and the movable clamping mechanism 220, and then the two sets of pressure plate mechanisms 230 cooperate with the fixed clamping mechanism 210 and the movable clamping mechanism 220 respectively to press and fix the film 500. Then, the driving component is started to drive the vertical plate 301 to move, and then the movable clamping mechanism 220 is driven to move through the tensile gauge 303, so that the movable clamping mechanism 220 moves away from the fixed clamping mechanism 210, thereby stretching the film 500.

[0026] When the value on the tensile gauge 303 reaches the preset value, if the film 500 is not damaged, it means that the tensile test result of the section of film 500 is qualified; if the film 500 is damaged, it means that the tensile test result of the section of film 500 is unqualified.

[0027] like Figure 2 and Figure 3As shown, the stretching testing equipment for the production of antistatic stretch film also includes a slide 101, a first mounting frame 102 and a second mounting frame 104. The slide 101 is opened on the workbench 100, and the vertical plate 301 passes through the slide 101; the first mounting frame 102 is installed on the bottom surface of the workbench 100; and the second mounting frame 104 is installed on the top surface of the workbench 100.

[0028] Specifically, the first mounting bracket 102 and the second mounting bracket 104 are both used to place the driving motor 306 in the driving assembly.

[0029] like Figure 4 As shown, the fixing clamping mechanism 210 includes a fixing plate 211 , a first fixing block 212 , a first rubber sheet 213 , two first electric push rods 214 and two first clamping blocks 215 .

[0030] The fixing plate 211 is fixedly installed on the top surface of the workbench 100; the first fixing block 212 is installed on the top surface of the fixing plate 211; the first rubber sheet 213 is installed on the top surface of the first fixing block 212; the two first electric push rods 214 are both installed on the top surface of the fixing plate 211; the two first clamping blocks 215 are respectively installed on the extended ends of the two first electric push rods 214, and the first clamping blocks 215 are provided with clamping grooves.

[0031] Specifically, when the two first electric push rods 214 are started, they will drive the two first clamping blocks 215 to move vertically.

[0032] like Figure 4 As shown, the movable clamping mechanism 220 includes a movable plate 221, a second fixed block 222, a second rubber sheet 223 and two second clamping blocks 225. The movable plate 221 is slidably connected to the top surface of the workbench 100; the second fixed block 222 is installed on the top surface of the movable plate 221, and the second fixed block 222 is connected to the tension gauge 303; the second rubber sheet 223 is installed on the top surface of the second fixed block 222; the two second electric push rods 224 are both installed on the top surface of the movable plate 221; the two second clamping blocks 225 are respectively installed at the extended ends of the two second electric push rods 224, and the second clamping blocks 225 are provided with clamping slots.

[0033] Specifically, when the two second electric push rods 224 are started, they will drive the two second clamping blocks 225 to move vertically.

[0034] like Figure 5 As shown, the pressing plate mechanism 230 includes an extrusion frame 231, two plug plates 232, a screw 233, a nut 234 and a third rubber sheet 235. The two plug plates 232 are respectively installed on both sides of the extrusion frame 231, and the plug plates 232 are plugged and matched with the first clamping block 215 and the second clamping block 225; the screw 233 passes through the extrusion frame 231; the nut 234 is threadedly connected with the screw 233; and the third rubber sheet 235 is installed on the bottom surface of the extrusion frame 231.

[0035] Specifically, when the two plug plates 232 on the extrusion frame 231 are plugged into the two first clamping blocks 215, the extrusion frame 231 is located directly above the fixed plate 211, and the third rubber sheet 235 is located directly above the first rubber sheet 213. At this time, the two first electric push rods 214 are started, and the two first electric push rods 214 will drive the two first clamping blocks 215 to move downward, thereby driving the plug plates 232 and the extrusion frame 231 to move downward, thereby shortening the distance between the third rubber sheet 235 and the first rubber sheet 213, thereby facilitating the third rubber sheet 235 and the first rubber sheet 213 to cooperate with each other to clamp the film 500.

[0036] When the two plug plates 232 on the extrusion frame 231 are plugged into the two second clamping blocks 225, the extrusion frame 231 is located directly above the movable plate 221, and the third rubber sheet 235 is located directly above the second rubber sheet 223. At this time, the two second electric push rods 224 are started, and the two second electric push rods 224 will drive the two second clamping blocks 225 to move downward, thereby driving the plug plates 232 and the extrusion frame 231 to move downward, thereby shortening the distance between the third rubber sheet 235 and the second rubber sheet 223, thereby facilitating the third rubber sheet 235 and the second rubber sheet 223 to cooperate in clamping the film 500.

[0037] like Figure 5 and Figure 6 As shown, the driving assembly includes a lead screw nut 302 , a lead screw 304 , a first insert cylinder 305 , a driving motor 306 and a square insert rod 307 .

[0038] The lead screw nut 302 is installed on the vertical plate 301; the lead screw 304 passes through the lead screw nut 302, and the lead screw 304 is rotatably connected to the bottom surface of the workbench 100; the first plug cylinder 305 is installed at one end of the lead screw 304; the drive motor 306 is placed on the first mounting frame 102; the square plug rod 307 is installed on the power output shaft of the drive motor 306, and the square plug rod 307 is plugged into the first plug cylinder 305.

[0039] Specifically, by placing the drive motor 306 on the first mounting frame 102, and using a tool to fix the drive motor 306 on the first mounting frame 102 to prevent the drive motor 306 from rotating and moving itself, the square plug rod 307 is plugged into the first plug tube 305. At this time, by starting the drive motor 306, the power output shaft of the drive motor 306 drives the square plug rod 307 to rotate, and then drives the first plug tube 305 to rotate, and then drives the lead screw 304 to rotate. When the lead screw 304 rotates, the lead screw nut 302 will move along the lead screw 304, and then drive the vertical plate 301 to move along the slide groove 101.

[0040] like Figure 1 , Figure 2 and Figure 7 As shown, the stretching detection equipment for producing antistatic stretch film also includes two sets of guide mechanisms 400, and the guide mechanism 400 includes a mounting plate 401, a rotating shaft 402, a second insert cylinder 403, a square block 404, a round rod 405, a cylinder 406, a square groove 407 and a through groove 408.

[0041] The mounting plate 401 is mounted on the top surface of the workbench 100; the rotating shaft 402 passes through the mounting plate 401 and is rotatably connected to the mounting plate 401; the second plug-in cylinder 403 is fixedly connected to one end of the rotating shaft 402; the square block 404 is fixedly connected to the end of the rotating shaft 402 away from the second plug-in cylinder 403; the round rod 405 is fixedly connected to the square block 404; the square groove 407 is provided on the cylinder 406, and the square groove 407 is plugged into the square block 404; the through groove 408 passes through the cylinder 406, and the through groove 408 is connected to the square groove 407, and the round rod 405 passes through the through groove 408.

[0042] Specifically, by providing two sets of guide mechanisms 400 , it is convenient to guide the film 500 that needs to be subjected to a tensile test to the fixed clamping mechanism 210 and the movable clamping mechanism 220 .

[0043] The cylinder 406 is provided with a square groove 407 and a through groove 408, so that the cylinder 406 can be separated from the square block 404 and the round rod 405. When the square groove 407 on the cylinder 406 is plugged into the square block 404 on the rotating shaft 402, rotating the rotating shaft 402 will drive the cylinder 406 to rotate.

[0044] Working principle: When in use, the film 500 to be subjected to the tensile test is passed through the two guide mechanisms 400, and then the film 500 is placed directly above the first fixed block 212 and the second fixed block 222, and then the two first electric push rods 214 and the two second electric push rods 224 are activated. The two first electric push rods 214 will drive the two first clamping blocks 215 to move downward, thereby driving the plug plate 232 and the extrusion frame 231 to move downward, thereby shortening the distance between the third rubber sheet 235 and the first rubber sheet 213, thereby facilitating the third rubber sheet 235 and the first rubber sheet 213 to cooperate to clamp the film 500.

[0045] The two second electric push rods 224 will drive the two second clamping blocks 225 to move downward, thereby driving the plug plate 232 and the extrusion frame 231 to move downward, thereby shortening the distance between the third rubber sheet 235 and the second rubber sheet 223, thereby facilitating the third rubber sheet 235 and the second rubber sheet 223 to cooperate to clamp the film 500.

[0046] Then, by starting the driving motor 306, the power output shaft of the driving motor 306 drives the square plug rod 307 to rotate, and then drives the first plug tube 305 to rotate, and then drives the lead screw 304 to rotate. When the lead screw 304 rotates, the lead screw nut 302 moves along the lead screw 304, and then drives the vertical plate 301 to move along the slide groove 101. Then, the active clamping mechanism 220 is driven to move through the tensile gauge 303, and then the active clamping mechanism 220 moves away from the fixed clamping mechanism 210, and then the film 500 is stretched.

[0047] When the value on the tensile gauge 303 reaches the preset value, observe whether the film 500 located between the movable clamping mechanism 220 and the fixed clamping mechanism 210 is damaged. If the film 500 is not damaged, it means that the tensile test result of this section of film 500 is qualified. If the film 500 is damaged, it means that the tensile test result of this section of film 500 is unqualified.

[0048] Then, the drive motor 306 is started again to drive the lead screw 304 to rotate in the opposite direction to reset the movable clamping mechanism 220, and the first electric push rod 214 and the second electric push rod 224 are started again to drive the two pressure plate mechanisms 230 to move upward, so that the fixed clamping mechanism 210 and the movable clamping mechanism 220 no longer clamp the film 500.

[0049] Then, the film 500 is pulled away from the guide mechanism 400, so that the untested section of the film 500 is between the fixed clamping mechanism 210 and the movable clamping mechanism 220, and the above operation is repeated to perform a stretching test on the film 500 between the fixed clamping mechanism 210 and the movable clamping mechanism 220. By performing multiple section tests on the long film 500, the accuracy of the test results can be improved.

[0050] Example 2: Figure 6-Figure 8 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: The second insert tube 403 is plugged into and matched with the square insert rod 307 .

[0051] Working principle: When not testing, the drive motor 306 is removed from the first mounting frame 102, and then the drive motor 306 is placed on the second mounting frame 104, and the square plug rod 307 installed on the power output shaft of the drive motor 306 is plugged into the second plug cylinder 403. Then, a tool is used to fix the drive motor 306 and the second mounting frame 104 to prevent the drive motor 306 from rotating on its own.

[0052] At this time, the drive motor 306 is started, and the power output shaft of the drive motor 306 will drive the square plug rod 307 to rotate, and then drive the second plug cylinder 403 to rotate, and then drive the rotating shaft 402 and the square block 404 to rotate, and then drive the cylinder 406 to rotate through the square groove 407, and the rotating cylinder 406 can be used in the winding process of the film 500 production, so that the device can not only perform stretching detection on the film 500, but also participate in the processing and production of the film 500, thereby improving the applicability of the device and improving the utilization rate of the device.

[0053] Example 3: Figure 9-11 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: The stretching testing device for the production of antistatic stretch film also includes a pusher 103 and two sets of supporting mechanisms 110. The pusher 103 is installed on the top surface of the workbench 100; the two sets of supporting mechanisms 110 are installed on the bottom surface of the workbench 100.

[0054] The support mechanism 110 includes a support block 111, two slots 112 and two baffles 113. The support block 111 is installed on the bottom surface of the workbench 100; the two slots 112 are both provided on the support block 111, and the two slots 112 are plugged and matched with the plugging plates 232; the two baffles 113 are both rotatably connected with the support block 111. The through slot 408 is plugged and matched with the screw rod 233.

[0055] Working principle: When the film 500 is not stretched and the device needs to be moved, the two extrusion frames 231 are taken out from between the two first clamping blocks 215 and the two second clamping blocks 225 respectively.

[0056] After the two nuts 234 are separated from the two screw rods 233 , the two screw rods 233 are separated from the two extrusion frames 231 respectively.

[0057] Then, the two cylinders 406 are moved away from the mounting plate 401 to separate the two cylinders 406 from the two round rods 405 .

[0058] Then, the cylinder 406 is placed in the extrusion frame 231, and the screw 233 penetrates the through groove 408 on the extrusion frame 231 and the cylinder 406. Then, the nut 234 is threadedly connected to the screw 233, so that the cylinder 406 is restricted in the extrusion frame 231, and the cylinder 406 is rotationally connected to the screw 233. Repeat this step to install the two cylinders 406 in the two extrusion frames 231 respectively.

[0059] Turn over the two extrusion racks 231 so that the cylinder 406 is located below the extrusion racks 231, then rotate the baffle 113 on the support block 111 so that the baffle 113 is parallel to the slot 112, then insert the two plug plates 232 on the extrusion rack 231 into the two slots 112, and then rotate the baffle 113 so that the baffle 113 blocks the extrusion rack 231 so that the extrusion rack 231 cannot be separated from the mounting plate 401 by itself. Repeat this step again to install the two extrusion racks 231 on the two support blocks 111 respectively.

[0060] At this time, the two cylinders 406 are in contact with the ground, and the two support blocks 111 are separated from the ground, so that the device can be easily moved by the push handle 103 and the cylinders 406, thereby improving the flexibility of the device.
