Description

Technical Field

[0001] This invention relates to the field of sheet material processing equipment technology, and in particular to a polymer sheet flexural strength testing device with a positioning mechanism. Background Technology

[0002] Polymer sheets, with their excellent properties such as wear resistance, corrosion resistance, and high toughness, are widely used in many fields such as chemical industry and building materials. In order to strictly control the quality of products leaving the factory and ensure that their performance meets the actual use requirements, polymer sheets usually need to be professionally tested for their flexural strength using flexural strength testing equipment after processing and production, so as to accurately evaluate the product quality.

[0003] In existing polymer sheet flexural strength testing equipment, to prevent sheet displacement during testing, a positioning mechanism is generally used to fix both ends of the sheet, and then a stamping mechanism applies pressure from the middle of the sheet downwards to complete the test. However, the positioning mechanism of existing equipment is mostly a fixed design. According to the physical characteristics of sheet flexural strength testing, when the stamping mechanism applies pressure to the middle of the sheet, the two ends of the sheet should naturally curl up in a V shape after the middle of the sheet is subjected to force, so as to truly reflect its flexural deformation process. However, due to the rigid constraint of the fixed positioning mechanism on the two ends of the sheet, the ends of the sheet cannot curl up freely. This not only easily leads to unexpected bending or breakage of the sheet at the clamping point of the positioning mechanism (which does not match the actual flexural failure scenario), but also interferes with the test data due to the limited deformation of the ends. Ultimately, this results in a large deviation in the sheet flexural strength test results, which cannot accurately reflect its true flexural strength performance. Summary of the Invention

[0004] This disclosure relates to a polymer sheet bending resistance testing device with a positioning mechanism. The device includes a limiting component. By inserting both ends of the sheet to be tested into the limiting component, and applying pressure to the middle of the sheet by a bending pusher, the limiting component, mounted on a fixed base with a rotating shaft, causes the two ends of the sheet to automatically tilt upwards after pressure is applied. This avoids the positioning structure restricting the free movement of the sheet ends, thus preventing the accuracy of the bending resistance test from being affected. The device also includes a clamping component. When the bending pusher moves downwards with the bending pusher, the transmission pusher and the pushing ring, in conjunction with multiple structures, push the driven pusher and the transmission rod forward. This causes the transmission rod to cooperate with the force groove to control the entire clamping component to move inwards. This inward movement of the clamping component limits the two ends of the sheet to be tested, ensuring the stability of the sheet during the test.

[0005] In a first aspect, this disclosure provides a polymer sheet bending resistance testing device with a positioning mechanism, specifically comprising: a support body, wherein fixed seats are fixedly installed on the left and right sides of the top of the support body; a follower shaft is rotatably mounted on the fixed seats; a mounting plate is fixedly installed at the rear end of the follower shaft; a torsion spring is installed between the mounting plate and the fixed seats; a limiting component is fixedly installed at the front end of the follower shaft; a sheet material to be tested is inserted into the limiting component; clamping components are symmetrically slidably installed on the outer wall of the limiting component; friction grooves are formed on the inner end of the clamping component; a baffle is fixedly installed on the outer side of the clamping component; the baffle is a rectangular structure; one end of a spring A is embedded in the inner side of the baffle; the other end of the spring A is embedded in the limiting component. On the outer wall; a force-bearing groove is formed inside the clamping member; a transmission rod is slidably installed on the rear side of the limiting member; a driven push plate is fixedly installed at the rear end of the transmission rod; a support plate is fixedly installed at the center of the top of the bracket body; the support plate has an L-shaped structure; a bending push cylinder is fixedly installed at the top of the support plate; a bending push component is fixedly installed on the output end of the bending push cylinder; a connecting rod is fixedly installed at the rear end of the bending push component; a transmission column is fixedly installed at the rear end of the connecting rod; a guide rod is fixedly installed on the rear side of the support plate; a transmission push component is slidably installed on the guide rod; a transmission plate is fixedly installed on the top of the transmission push component; a transmission groove is formed on the outer wall of the transmission plate; and push rings are fixedly installed at the left and right ends of the transmission push component.

[0006] The inner end of the force-receiving groove is inclined; the front end of the transmission rod is inclined; the inclined surface of the transmission rod is in close contact with the inclined surface of the force-receiving groove; one end of the spring B is embedded in the front side of the driven push plate; the other end of the spring B is embedded in the rear side wall of the limiting member; the bending push member is located above the plate to be tested; the connecting rod is also slidably installed on the support plate; and the transmission column is cylindrical.

[0007] The guide rod is cylindrical; one end of a spring C is embedded inside the transmission pusher; the other end of the spring C is embedded in the rear side wall of the support plate; the transmission groove consists of an inclined groove and a vertical groove, with the lowest end of the inclined groove connected to the highest end of the vertical groove; the transmission column is also slidably installed inside the transmission groove.

[0008] The push ring is a circular ring structure; the push ring is also slidably mounted on the follower rotating shaft; the push ring is located on the rear side of the driven push plate; a stress-relieving ball is rotatably mounted on the front side of the push ring; the outer wall of the stress-relieving ball contacts the rear side wall of the driven push plate; when the bending push cylinder moves downward with the bending push component, the bending push component will move downward with the connecting rod and the transmission column.

[0009] When the transmission column moves downward, it uses the inclined groove of the transmission groove to convert the downward force into a forward force, which is then provided to the transmission plate and the transmission pusher. When the transmission pusher moves forward, the pushing ring and the force-dissipating ball on the transmission pusher push the driven push plate forward. When the driven push plate moves forward, the inclined surface of the transmission rod on the driven push plate pushes the inclined surface of the force-receiving groove. After being pushed, the inclined surface of the force-receiving groove moves inward along with the clamping member.

[0010] This invention provides a polymer sheet bending resistance testing device with a positioning mechanism, which has the following beneficial effects: 1. This bending resistance test equipment is equipped with limiting components. During use, the two ends of the board to be tested are clamped inside the limiting components. When the middle of the board to be tested is pushed and pressed by the bending pusher, the limiting components are installed on the fixed seat by rotating through the follower shaft. After the middle of the board to be tested is pressed, the two ends of the board can automatically lift up. This effectively avoids the interference caused by the traditional positioning structure restricting the free deformation of the board ends, which affects the accuracy of the bending resistance test. This ensures that the test data can truly reflect the bending resistance performance of the board.

[0011] 2. This bending resistance test equipment is also equipped with a clamping component. When the bending push cylinder drives the bending pusher to move downward, the transmission pusher and the push ring will push the driven push plate and transmission rod forward under the coordinated action of multiple components. The transmission rod then cooperates with the force groove to drive the entire clamping component to move inward. The inward movement of the clamping component realizes the limiting and fixing of both ends of the plate to be tested, thereby ensuring the positional stability of the plate to be tested throughout the bending resistance test and preventing test deviation caused by plate displacement.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please refer to Figures 1 to 8 : Example 1: This invention proposes a polymer sheet bending resistance testing device with a positioning mechanism, comprising: a support body 1, with fixed seats 2 fixedly installed on the top left and right sides of the support body 1; a follower shaft 3 rotatably installed on the fixed seats 2; a mounting plate 4 fixedly installed at the rear end of the follower shaft 3; a torsion spring 5 installed between the mounting plate 4 and the fixed seats 2; a limiting component 6 fixedly installed at the front end of the follower shaft 3; a sheet material 26 to be tested inserted into the limiting component 6; clamping components 7 symmetrically slidably installed on the outer wall of the limiting component 6; friction grooves are formed on the inner end of the clamping component 7; a baffle 8 is fixedly installed on the outer side of the clamping component 7; the baffle 8 has a rectangular structure; the baffle 8... One end of spring A9 is embedded in the inner side; the other end of spring A9 is embedded in the outer wall of the limiting member 6; a force groove 10 is opened inside the clamping member 7; a transmission rod 11 is slidably installed on the rear side of the limiting member 6; a driven push plate 12 is fixedly installed at the rear end of the transmission rod 11; a support plate 14 is fixedly installed at the center of the top of the bracket body 1; the support plate 14 has an L-shaped structure; a bending push cylinder 15 is fixedly installed at the top of the support plate 14; a bending pusher 16 is fixedly installed on the output end of the bending push cylinder 15; a connecting rod 17 is fixedly installed at the rear end of the bending pusher 16; a transmission column 18 is fixedly installed at the rear end of the connecting rod 17; the support plate 1 A guide rod 19 is fixedly installed on the rear side of 4; a transmission pusher 20 is slidably installed on the guide rod 19; a transmission plate 22 is fixedly installed on the top of the transmission pusher 20; a transmission groove 23 is opened on the outer wall of the transmission plate 22; push rings 24 are fixedly installed on the left and right ends of the transmission pusher 20; by inserting the two ends of the plate to be tested 26 into the interior of the two limiting members 6 respectively, and then by activating the bending pusher 15, the bending pusher 15 moves the bending pusher 16 downward. During the movement, the bending pusher 16 will move the connecting rod 17 and the transmission column 18 downward, so that the transmission column 18 uses the inclined groove of the transmission groove 23 to convert the downward force into the forward force. The transfer force is provided to the transmission plate 22 and the transmission pusher 20, causing the transmission pusher 20 to move forward with the push ring 24 and the force-dissipating ball 25. The push ring 24 and the force-dissipating ball 25 push the driven push plate 12 forward, causing the driven push plate 12 to be forced to move the transmission rod 11 forward. During the forward movement, the inclined surface of the transmission rod 11 will push against the inclined surface of the force groove 10, causing the force groove 10 to be forced to move the clamping member 7 inward. The clamping member 7 clamps and limits the two ends of the plate 26 to be tested inside the two limiting members 6 by moving inward. Then, when the bending pusher cylinder 15 continues to descend, the bending pusher 16 will push and bend the plate 26 to be tested from the middle.

[0017] In Example 2, based on Example 1, the inner end of the force-receiving groove 10 has an inclined structure; the front end of the transmission rod 11 has an inclined structure; the inclined surface of the transmission rod 11 is in close contact with the inclined surface of the force-receiving groove 10; one end of the spring B13 is embedded and installed on the front side of the driven push plate 12; the other end of the spring B13 is embedded and installed on the rear side wall of the limiting member 6; the bending push member 16 is located above the plate 26 to be tested; the connecting rod 17 is also slidably installed on the support plate 14; the transmission column 18 has a cylindrical structure; the guide rod 19 has a cylindrical structure; and a spring C21 is embedded and installed inside the transmission push member 20. The other end of the spring C21 is embedded in the rear side wall of the support plate 14; the transmission groove 23 consists of an inclined groove and a vertical groove, and the lowest end of the inclined groove is connected to the highest end of the vertical groove; the transmission column 18 is also slidably installed inside the transmission groove 23; during the bending process, since the limiting member 6 is rotated and installed on the fixed seat 2 through the follower shaft 3, after the middle of the plate to be tested 26 is bent under pressure, both ends of the plate to be tested 26 will also be raised in a V shape by the rotation of the limiting member 6, so that the plate to be tested 26 will not be locally restricted during the test, resulting in insufficient accuracy of its own bending test.

[0018] In Example 3, based on Example 2, the pushing ring 24 has a circular structure; the pushing ring 24 is also slidably mounted on the follower rotating shaft 3; the pushing ring 24 is located on the rear side of the driven push plate 12; a force-dissipating ball 25 is rotatably mounted on the front side of the pushing ring 24; the outer wall of the force-dissipating ball 25 contacts the rear side wall of the driven push plate 12; when the bending push cylinder 15 moves downward with the bending push member 16, the bending push member 16 will move downward with the connecting rod 17 and the transmission column 18; the transmission column 18 moves downward... During movement, the inclined groove of the transmission groove 23 converts the downward force into a forward force, which is then supplied to the transmission plate 22 and the transmission pusher 20. When the transmission pusher 20 moves forward, the push ring 24 and the force-dissipating ball 25 on the transmission pusher 20 push the driven push plate 12 forward. When the driven push plate 12 moves forward, the inclined surface of the transmission rod 11 on the driven push plate 12 pushes the inclined surface of the force-receiving groove 10. After being pushed, the inclined surface of the force-receiving groove 10 moves inward along with the clamping member 7. After the test is completed, the bending push cylinder 15 is restored, causing it to move upward along with the bending push component 16. This cancels the pushing action of the bending push component 16 on the test plate 26. The bending push component 16, along with the connecting rod 17 and the transmission column 18, moves upward, causing the transmission column 18 to cancel the pushing action on the inclined section of the transmission groove 23. Under the action of the spring C21, the transmission push component 20 moves backward along with the push ring 24 and the stress-relieving ball 25. This backward movement of the stress-relieving ball 25 cancels its action on the driven push plate 12. The push of the spring causes the driven push plate 12 to move backward along the transmission rod 11 under the action of the spring B13, so that the transmission rod 11 cancels the push of the force groove 10, and the clamping member 7 returns to its original position under the action of the spring A9, thus canceling the clamping of the plate 26 to be tested. After the bending push member 16 returns to its original position, the follower rotating shaft 3 will also return to its original position along with both ends of the plate 26 to be tested under the action of the torsion spring 5. This makes it easier to remove the polymer plate after testing and also makes it easier to install other plates 26 to be tested.

[0019] The working principle of this embodiment: In use, the two ends of the test plate 26 are inserted into the two limiting members 6 respectively. Then, by activating the bending push cylinder 15, the bending push cylinder 15 moves downward with the bending push member 16. During the movement, the bending push member 16 moves downward with the connecting rod 17 and the transmission column 18. The transmission column 18 uses the inclined groove of the transmission groove 23 to convert the downward force into a forward force, which is provided to the transmission plate 22 and the transmission push member 20. The transmission push member 20 moves forward with the pushing ring 24 and the force-dissipating ball 25. The pushing ring 24 and the force-dissipating ball 25 push the driven push plate 12 forward. The driven push plate 12 is forced to move the transmission rod 11 forward. During this forward movement, the inclined surface of the transmission rod 11 pushes against the inclined surface of the force groove 10, causing the force groove 10 to move inward along with the clamping member 7. The clamping member 7 clamps and limits both ends of the test plate 26 inside the two limiting members 6 by moving inward. Then, as the bending push cylinder 15 continues to descend, the bending push member 16 pushes and bends the test plate 26 from the middle. During the bending process, since the limiting members 6 are mounted on the fixed seat 2 by rotating the follower shaft 3, after the test plate 26 is bent under pressure in the middle, the test plate... The two ends of the plate 26 will also be V-shaped and raised by the rotation of the limiting part 6, so that the plate 26 under test will not be locally restricted during the test, resulting in insufficient accuracy of its own bending resistance test. After the test, by restoring the bending push cylinder 15, it moves the bending push part 16 upward, so that the bending push part 16 cancels the pushing of the plate 26 under test, so that the bending push part 16 moves the connecting rod 17 and the transmission column 18 upward, so that the transmission column 18 cancels the pushing of the inclined groove of the transmission groove 23, so that the transmission push part 20, under the action of the spring C21, moves the pushing ring 24 and the force-dissipating part. The ball bearing 25 moves backward, causing the force-dissipating ball bearing 25 to cancel its pushing force on the driven push plate 12. Under the action of the spring B13, the driven push plate 12 moves backward along with the transmission rod 11, causing the transmission rod 11 to cancel its pushing force on the force groove 10. Under the action of the spring A9, the clamping member 7 returns to its original position and cancels its clamping force on the test plate 26. After the bending push member 16 returns to its original position, the follower rotating shaft 3 will also return to its original position along with both ends of the test plate 26 under the action of the torsion spring 5. This makes it easier to remove the polymer plate after testing and also makes it easier to install other test plates 26 in the future.
