Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology, specifically to a tensile testing machine for geomembrane production. Background Technology

[0002] Geomembrane is a waterproof and barrier material made primarily of polymers (such as polyethylene and polyvinyl chloride). A tensile testing machine used in geomembrane production is a specialized device for testing the tensile properties of geomembranes. This machine applies tensile force to test the geomembrane's tensile strength, elongation at break, and other mechanical properties. These indicators are crucial for evaluating the quality and performance of geomembranes and help manufacturers ensure product quality.

[0003] CN218412022U discloses a geomembrane weld tensile testing device, including a base; a vertical plate fixedly installed on the top of the base; a moving mechanism disposed on one side of the vertical plate; the moving mechanism includes: a first electric push rod fixedly installed on one side of the vertical plate; a fixing plate fixedly installed on one side of the first electric push rod; and a clamping mechanism disposed on one side of the fixing plate. This invention pre-fixes the geomembrane by placing one end of the geomembrane under a second pressure block, activating the second electric push rod to move the second pressure block downwards, and then placing the other end of the geomembrane under the first pressure block, rotating a rotating rod, which drives a lead screw to rotate, and the lead screw to move the first pressure block downwards, thus completing the fixing of the geomembrane. The device is easy to operate and has a good fixing effect.

[0004] While the existing technology CN218412022U has many advantages in use, it still has the following problems: its adaptability to the clamping range is not perfect. Different sizes of geomembranes require different sizes of clamping plates for clamping and fixing, but its adaptability to equipment is poor. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a tensile testing machine for geomembrane production.

[0006] The technical solution adopted by this utility model to solve its technical problem is a tensile testing machine for geomembrane production, including a base plate, support blocks, bearing seats, and extension blocks. A lead screw body is provided on the upper outer wall of the base plate, and support seats are threadedly connected to both outer walls of the lead screw body. A tensile sensor is installed on one outer wall of the support seat, and a support plate is installed on the outer wall of the side of the tensile sensor facing away from the support seat. Support blocks are provided on both sides of the upper outer wall of the support plate. A movable groove is formed inside the support block, and a limit groove is formed on one side of the inner wall of the movable groove. Extension blocks are arranged in parallel at equal intervals inside the movable groove. Bearing seats are installed on both outer walls of the support plate, and screws are rotatably installed inside the bearing seats. The rod, comprising a base plate, a support block, a bearing seat, and an extension block, includes a limit block welded to one side of the outer wall of the extension block. A lead screw body is mounted on the upper outer wall of the base plate. Support seats are threaded onto both sides of the lead screw body. A tension sensor is mounted on one side of the outer wall of the support seat. A support plate is mounted on the outer wall of the tension sensor facing away from the support seat. Support blocks are mounted on both sides of the upper outer wall of the support plate. A movable groove is formed inside the support block. A limit groove is formed on one side of the inner wall of the movable groove. Extension blocks are equidistantly and parallelly distributed inside the movable groove. Bearing seats are mounted on both sides of the outer wall of the support plate. A screw is rotatably mounted inside the bearing seats. A limit block is welded to one side of the outer wall of the extension block.

[0007] By adopting the above technical solution, the base can maintain the stable position of the lead screw body, and the lead screw body can drive the two support seats to move in opposite directions or away from each other, thereby adjusting the distance between the two support seats. This enables the tensile testing of the clamped geomembrane, and the tensile sensor detects the tensile data of the geomembrane, accurately testing the mechanical properties of the geomembrane. The rotation of the screw can adjust the distance between the linkage blocks, and the extension tube can extend out of the movable slot, so that the extension block is between the clamping plates, thereby realizing the adjustment of the overall clamping surface and ensuring that the equipment can adapt to the clamping and fixing requirements of different sizes.

[0008] Specifically, connectors are welded to the outer walls on both sides of the two support blocks, and bolts are installed inside the connectors. The support blocks are connected to each other through the connectors and bolts.

[0009] By adopting the above technical solution, the connector can connect the two support blocks, enhancing the stability between the support blocks. When the geomembrane is located between the clamping plates, it can be clamped and fixed, which helps to prevent the support blocks from deforming or displacing during the test, thereby improving the accuracy and reliability of the test.

[0010] Specifically, the lower outer wall of the extension block is provided with a storage groove, and a spring is provided inside the storage groove. The extension block is elastically connected to the lower end of the inner wall of the movable groove through the spring.

[0011] By adopting the above technical solution, the spring force can push out the extension block, allowing the extension block to enter between the clamping plates, ensuring that the sample can be uniformly stressed during the test, avoiding test errors caused by improper clamping, and maintaining the clamping plate's firmness in clamping the geomembrane.

[0012] Specifically, the opening directions of the threads on both sides of the screw are opposite, and the outer walls on both sides of the screw are threaded with linkage blocks. A clamping plate is welded to the outer wall of one end of the linkage block, and the clamping plate is located at the upper end of the extension block.

[0013] By adopting the above technical solution, the opening directions of the threads on both sides of the screw are opposite, which allows the rotating screw to simultaneously push the linkage blocks and clamping plates on both sides towards the center, thereby adjusting the distance between the clamping plates and realizing the adjustment of the overall clamping surface size, thus enabling the clamping of geomembrane samples of different sizes. This design simplifies the clamping operation, improves work efficiency, and ensures a uniform distribution of clamping force.

[0014] Specifically, both the inner walls of the movable groove and the limiting groove are designed in a rectangular shape, the size of the limiting block is smaller than the size of the limiting groove, and the limiting block is located inside the limiting groove.

[0015] By adopting the above technical solution, the limiting block restricts the movement trajectory of the extension block, ensuring that after the extension block protrudes from the movable groove, the upper end surface of the extension block and the upper end surface of the clamping plate are at the same horizontal plane. The movable groove and the limiting groove ensure the vertical movement stability of the extension block, which helps to prevent the extension block from deflecting or shaking during movement, thereby improving the accuracy and stability of the test.

[0016] Specifically, the limiting block has a through hole inside, and the upper and lower sides of the inner wall of the through hole are designed with an arc shape. A connecting rod is installed inside the through hole.

[0017] By adopting the above technical solution, the operator can drive and reset the overall limiting block and extension block by pressing the connecting rod, ensuring the smooth reset of the extension block and improving the operator's operating speed. When the limiting block moves with the extension block driven by the spring, the through hole ensures that the connecting rod can adapt to the limiting block in different positions.

[0018] Specifically, the outer wall of the base plate is welded with a rectangular array of fixing blocks, and fixing holes are provided inside the fixing blocks.

[0019] By adopting the above technical solution, the staff can insert screws through the fixing holes, so that the base plate can be firmly fixed to the ground. This design improves the overall stability and safety of the testing machine and avoids testing errors or safety accidents caused by the movement or tilting of the testing machine during the testing process.

[0020] The beneficial effects of this utility model are:

[0021] (1) The tensile testing machine for geomembrane production described in this utility model allows the extension block to be positioned between the clamping blocks, thereby enabling adjustment of the overall clamping surface and ensuring that the equipment can adapt to clamping and fixing requirements of different sizes.

[0022] (2) The tensile testing machine for geomembrane production described in this utility model ensures the vertical movement stability of the extension block, helps prevent the extension block from deflecting or shaking during movement, thereby improving the accuracy and stability of the test, simplifying the clamping operation, improving work efficiency, and ensuring the uniform distribution of clamping force.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the tensile testing machine for geomembrane production of this utility model includes a base plate 1, a support block 2, a bearing seat 3, and an extension block 4. A lead screw body 11 is provided on the upper outer wall of the base plate 1. Support seats 12 are threadedly connected to both outer walls of the lead screw body 11. A tensile sensor 13 is installed on one outer wall of the support seat 12. A support plate 14 is installed on the outer wall of the tensile sensor 13 away from the support seat 12. Support blocks 2 are provided on both sides of the upper outer wall of the support plate 14. A movable groove 22 is opened inside the support block 2. A limit groove 23 is opened on one side of the inner wall of the movable groove 22. Extension blocks 4 are arranged in parallel at equal intervals inside the movable groove 22. Bearing seats 3 are installed on both outer walls of the support plate 14. A screw 31 is rotatably installed inside the bearing seat 3. A limit block 43 is welded to one outer wall of the extension block 4.

[0031] During use, the base can keep the screw body 11 in a stable position, and the screw body 11 can drive the two support seats 12 to move towards or away from each other, thereby adjusting the distance between the two support seats 12. This enables the tensile testing of the clamped geomembrane, and the tensile sensor 13 detects the tensile data of the geomembrane, accurately testing the mechanical properties of the geomembrane. The rotation of the screw 31 can adjust the distance between the linkage blocks 32, and the extension tube can extend out of the movable groove 22, so that the extension block 4 is between the clamping plates 33, thereby adjusting the overall clamping surface and ensuring that the equipment can adapt to clamping and fixing requirements of different sizes.

[0032] For clamping and securing, exemplarily, such as Figure 2 As shown, connectors 21 are welded to the outer walls on both sides of the two support blocks 2. Bolts are installed inside the connectors 21, and the support blocks 2 are connected to each other through the connectors 21 and the bolts.

[0033] When in use, the connector 21 can connect the two support blocks 2, which enhances the stability between the support blocks 2. When the geomembrane is located between the clamping plates 33, it can be clamped and fixed, which helps to prevent the support blocks 2 from deforming or displacing during the test, thereby improving the accuracy and reliability of the test.

[0034] To drive movement, for example, such as Figure 4 As shown, a storage groove 41 is provided on the lower outer wall of the extension block 4, and a spring 42 is provided inside the storage groove 41. The extension block 4 is elastically connected to the lower end of the inner wall of the movable groove 22 through the spring 42.

[0035] When in use, the spring 42 can push out the extension block 4, so that the extension block 4 enters between the clamping plates 33, ensuring that the sample can be evenly stressed during the test, avoiding test errors caused by improper clamping, and maintaining the clamping plate 33's firm clamping of the geomembrane.

[0036] To adjust the spacing, for example, such as Figure 3 As shown, the opening directions of the threads on both sides of the screw 31 are opposite. Both sides of the outer wall of the screw 31 are threaded with linkage blocks 32. A clamping plate 33 is welded to the outer wall of one end of the linkage block 32. The clamping plate 33 is located at the upper end of the extension block 4.

[0037] In use, the threads on both sides of the screw 31 open in opposite directions, so that rotating the screw 31 simultaneously pushes the linkage blocks 32 on both sides and the clamping plates 33 towards the center, thereby adjusting the distance between the clamping plates 33 and realizing the adjustment of the overall clamping surface size, thus enabling the clamping of geomembrane samples of different sizes. This design simplifies the clamping operation, improves work efficiency, and ensures a uniform distribution of clamping force.

[0038] For vertical movement, for example, such as Figure 4 As shown, the inner walls of both the movable groove 22 and the limiting groove 23 are designed in a rectangular shape. The size of the limiting block 43 is smaller than that of the limiting groove 23, and the limiting block 43 is located inside the limiting groove 23.

[0039] During use, the limiting block 43 restricts the movement trajectory of the extension block 4, ensuring that after the extension block 4 protrudes from the movable groove 22, the upper end surface of the extension block 4 is at the same level as the upper end surface of the clamping plate 33. The movable groove 22 and the limiting groove 23 ensure the vertical movement stability of the extension block 4, which helps to prevent the extension block 4 from deflecting or shaking during movement, thereby improving the accuracy and stability of the test.

[0040] For synchronized adjustment, for example, such as Figure 4 As shown, the limiting block 43 has a through hole 44 inside. The upper and lower sides of the inner wall of the through hole 44 are designed with an arc shape, and a connecting rod 45 is installed inside the through hole 44.

[0041] During use, by pressing the connecting rod 45, the operator can drive and reset the overall limiting block 43 and the extension block 4, ensuring the smooth reset of the extension block 4 and improving the operator's operating speed. When the limiting block 43 moves with the extension block 42 driven by the spring 42, the through hole 44 ensures that the connecting rod 45 can adapt to the limiting block 43 in different positions.

[0042] To use a fixed position, for example, such as Figure 1 As shown, a rectangular array of fixing blocks is welded to the outer wall of the base plate 1, and fixing holes are provided inside the fixing blocks.

[0043] During use, the operator can insert screws through the fixing holes to firmly fix the base plate 1 to the ground. This design improves the overall stability and safety of the testing machine and avoids testing errors or safety accidents caused by the movement or tilting of the testing machine during the testing process.

[0044] When this utility model is in use, rotating the screw 31 will cause the connecting blocks 32 and the clamping plate 33 on both sides to move away from each other because the opening directions of the threads on both sides of the screw 31 are opposite. As the extension block 4 is released from the constraint of the clamping plate 33, the extension block 4 is pushed out by the spring force of the spring 42, thereby filling the space between the clamping plates 33. The clamping plate 33 and the extension block 4 form an integral clamping surface, ensuring that the size of the integral clamping surface is compatible with the size of the geomembrane.

[0045] The staff placed the geomembrane on the upper end of the clamping plate 33 of the lower support block 2, and then the staff took the upper support block 2 and placed it. The two support blocks 2 were connected by the connector 21. The clamping plate 33 and the extension block 4 can be used to clamp and fix the geomembrane.

[0046] The drive screw body 11 rotates, thereby pushing the support seat 12 and the tension sensor 13 to move along the screw body 11. The tension sensor 13 will detect and record the tension data of the geomembrane sample in real time during the stretching process.

[0047] Afterwards, the staff can separate the two support blocks 2 using the connector 21 to release the geomembrane. The staff can also manually press the connecting rod 45 to simultaneously drive and reset multiple limit blocks 43 and extension blocks 4.

[0048] It should be noted that this utility model is a tensile testing machine for geomembrane production. All components in this utility model are known to those skilled in the art, and their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
