Description

Technical Field

[0001] This utility model relates to the field of CPE film processing and testing technology, specifically to an electronic tensile testing machine for CPE film products. Background Technology

[0002] Currently, most electronic tensile testing machines use a screw drive structure to move and clamp the upper and lower clamping components. Both the upper and lower clamping rods are connected to the clamping blocks via screws. Operators need to rotate the screws separately to control the movement of the upper and lower clamping blocks to clamp the CPE film. However, this split screw drive structure has obvious defects: because the operation of the screws in the upper and lower clamping blocks is independent, it is difficult to ensure the consistency of the degree of rotation and the transmission distance, resulting in the upper and lower clamping blocks not being able to move synchronously. This causes uneven force on the upper and lower ends of the CPE film when it is clamped, which can easily lead to problems such as tilting and twisting. Therefore, an electronic tensile testing machine for CPE film products is proposed. Utility Model Content

[0003] This invention proposes a quick-installation expansion bolt, which solves the problem of tilting caused by uneven force distribution in electronic tensile testing machines for CPE film products, where the operation of the lead screws in the upper and lower clamping blocks is independent, making it difficult to ensure the consistency of rotation degree and transmission distance.

[0004] According to one aspect, at least one embodiment of the present invention provides an electronic tensile testing machine for CPE film products, comprising: The electronic tensile testing machine body has an upper clamping and lifting component on its surface and a lower clamping and fixing component at its bottom. The upper clamping and lifting component has an upper clamping block inside, and the lower clamping and fixing component has a lower clamping block inside. The upper clamping block has a lead screw on its side. The upper clamping block is connected to the upper clamping and lifting member in a helical transmission relationship through the lead screw on its side. The lead screw on the side of the upper clamping block passes through the upper clamping and lifting member and is fixedly connected to a rotating handle. A rotating handle has a first stabilizing groove inside. A first stabilizing block is slidably fitted inside the first stabilizing groove. An extension rod is fixedly connected to the first stabilizing block through the first stabilizing groove. A sliding groove is provided on the inner wall of the extension rod. An extension rod is slidably connected to the extension rod through the sliding groove. Another sliding groove is slidably fitted at the other end of the extension rod. Another rotating handle, a first stabilizing groove, a first stabilizing block, and an extension rod are provided on the side of the lower clamping block. The other extension rod is fixedly connected to the other sliding groove.

[0005] For example, at least one embodiment of the present invention provides an electronic tensile testing machine for a CPE film product, which further includes: the first stabilizing groove is circular in shape, the first stabilizing block is attached to the first stabilizing groove, and the first stabilizing block is arc-shaped.

[0006] For example, at least one embodiment of the present invention provides an electronic tensile testing machine for a CPE film product, which further includes: a second stabilizing groove is provided on the side of the lower clamping block, a stabilizing rod is slidably connected inside the second stabilizing groove, a second stabilizing block is fixedly connected inside the stabilizing rod, and the lower clamping block and another rotating handle are fixedly connected to each other through the second stabilizing block.

[0007] For example, at least one embodiment of the present invention provides an electronic tensile testing machine for a CPE film product, which further includes: an insertion rod fixedly connected to the outer end of the rotating handle, a sleeve block sleeved on the outside of the insertion rod, and the inner wall of the sleeve block being in contact with the outer side of the first stabilizing block.

[0008] For example, at least one embodiment of the present invention provides an electronic tensile testing machine for a CPE film product, which further includes: a first auxiliary groove is provided inside the sleeve block, a pressing block is movably arranged inside the first auxiliary groove, a second auxiliary groove is provided inside the insert rod, a limiting block is movably arranged inside the second auxiliary groove, and the limiting block passes through the second auxiliary groove and is inserted into the first auxiliary groove.

[0009] For example, at least one embodiment of the present invention provides an electronic tensile testing machine for a CPE film product, which further includes: a first spring is provided inside the first auxiliary groove, the first spring is wound around the outside of the pressing block, a second spring is provided inside the second auxiliary groove, one end of the second spring is fixedly connected to the inner wall of the second auxiliary groove, and the other end of the second spring is fixedly connected to the limiting block.

[0010] For example, at least one embodiment of the present invention provides an electronic tensile testing machine for CPE film products, which further includes: the first auxiliary groove, the pressing block, the first spring, the second auxiliary groove, the limiting block and the second spring are all arranged symmetrically inside the sleeve block and the insertion rod.

[0011] For example, at least one embodiment of the present invention provides an electronic tensile testing machine for a CPE film product, which further includes: the outer wall of the pressing block and the inner wall of the first auxiliary groove are mutually attached, and the outer wall of the limiting block and the inner wall of the second auxiliary groove are mutually attached.

[0012] The working principle and beneficial effects of this utility model are as follows: The upper clamping block is connected to the rotating handle via a lead screw. When the rotating handle moves the upper clamping block, the first stabilizing block inside the rotating handle rotates in the first stabilizing groove under the action of gravity, keeping the extension sleeve rod in a vertical state. It is connected to the extension sleeve rod on the side of the lower clamping block through the extension rod, realizing the linkage between the upper and lower clamping blocks. When the upper clamping block moves to clamp the upper end of the CPE film, the lower clamping block can slide synchronously through the extension sleeve rod and the extension rod, ensuring that the upper and lower ends of the CPE film are subjected to uniform clamping force, effectively avoiding the tilting problem caused by uneven force, and improving the accuracy of tensile force detection. The insertion rod and sleeve block structure at the outer end of the handle allows for quick release of the sleeve block and insertion rod by pressing the limiting block with the pressing block. This facilitates the disassembly of components such as the first stabilizing block and the extension sleeve block. It also allows for the rapid replacement of extension components of different lengths to meet the testing requirements of different CPE film specifications, significantly expanding the applicability of the equipment. The second stabilizing groove on the side of the lower clamping block cooperates with the stabilizing rod, enabling the lower clamping block to move equidistantly along the guide of the stabilizing rod under the drive of the second stabilizing block when the upper clamping block moves. This reduces swaying during movement and enhances the stability of the synchronous movement of the upper and lower clamping blocks. Simultaneously, the first and second springs ensure that the pressing block and limiting block automatically reset when no external force is applied, guaranteeing the reusability of the disassembly structure and improving the ease of operation and testing efficiency of the equipment.

[0021] like Figures 1-4 As shown, it illustrates an electronic tensile testing machine for a CPE film product according to one embodiment of the present invention. In some examples, it includes... The electronic tensile testing machine body 1 has an upper clamping and lifting component 2 on its surface and a lower clamping and fixing component 3 at its bottom. The upper clamping and lifting component 2 has an upper clamping block 4 inside, and the lower clamping and fixing component 3 has a lower clamping block 5 inside. The upper clamping block 4 has a lead screw on its side. The upper clamping block 4 is connected to the upper clamping and lifting member 2 in a spiral transmission relationship through the lead screw on its side. The lead screw on the side of the upper clamping block 4 passes through the upper clamping and lifting member 2 and is fixedly connected to a rotating handle 6. A rotating handle 6 has a first stabilizing groove 7 inside. A first stabilizing block 8 is slidably sleeved inside the first stabilizing groove 7. An extension sleeve 9 is fixedly connected to the first stabilizing block 8 through the first stabilizing groove 7. A sliding groove 10 is formed on the inner wall of the extension sleeve 9. An extension rod 11 is slidably connected to the extension sleeve 9 through the sliding groove 10. Another sliding groove 10 is slidably sleeved at the other end of the extension rod 11. Another rotating handle 6, the first stabilizing groove 7, the first stabilizing block 8, and the extension sleeve 9 are arranged on the side of the lower clamping block 5. The other extension sleeve 9 is fixedly connected to the other sliding groove 10. When tensile testing of the CPE film is required, the upper clamping block 4 is driven by the screw drive of the rotating handle 6 to clamp the upper part of the CPE film. At this time, the clamping of the upper clamping block 4 and the rotation of the rotating handle 6 are simultaneous. The first stabilizing block 8 rotates inside the first stabilizing groove 7 under the action of gravity, thereby causing the extension sleeve to... Rod 9 will remain perpendicular to the handle 6. Since the lower clamping block 5 and the lower clamping fixing member 3 are in a sliding connection relationship, rather than the threaded screw drive connection relationship between the upper clamping block 4 and the upper clamping lifting member 2, the lower clamping block 5 will slide inside the lower clamping fixing member 3 under the drive of the extension sleeve rod 9 and the extension rod 11, and clamp the lower end of the CPE film. The above operation and structure are to ensure that the CPE film as a whole remains relatively synchronized when clamped by the upper clamping block 4 and the lower clamping block 5, and is in a vertical state. This avoids the problem that the CPE film cannot be in a normal vertical angle due to the different clamping forces of the upper clamping block 4 and the lower clamping block 5, resulting in inaccurate tensile testing. In addition, when the tensile test is performed, the upper clamping block 4 moves, and the extension sleeve rod 9 and the extension rod 11 will move accordingly, maintaining relative vertical synchronization, further improving the testing efficiency.

[0022] Then, the first stabilizing groove 7 is circular in shape, and the first stabilizing block 8 fits into the first stabilizing groove 7. The first stabilizing block 8 is arc-shaped. The above structure ensures that while the handle 6 is turned, the first stabilizing block 8 and the extension sleeve 9 remain relatively perpendicular to the horizontal plane due to gravity, thus ensuring the operation effect of the extension sleeve 9.

[0023] Subsequently, a second stabilizing groove 21 is provided on the side of the lower clamping block 5. A stabilizing rod 22 is slidably connected inside the second stabilizing groove 21. A second stabilizing block 20 is fixedly connected inside the stabilizing rod 22. The lower clamping block 5 and another rotating handle 6 are fixedly connected to each other through the second stabilizing block 20. The above operation ensures that the lower clamping block 5 will move the same distance relative to the upper clamping block 4 during the movement. Furthermore, the contact between the stabilizing rod 22 and the second stabilizing groove 21 ensures that the movement of the lower clamping block 5 driven by the second stabilizing block 20 is more stable, thus ensuring the stability and accuracy of the synchronous movement of the upper clamping block 4 and the lower clamping block 5.

[0024] Next, a plug rod 12 is fixedly connected to the outer end of the rotating handle 6. A sleeve block 13 is sleeved on the outside of the plug rod 12. The inner wall of the sleeve block 13 fits against the outer side of the first stabilizing block 8. Through the above structure, after the sleeve block 13 is detached from the plug rod 12, the first stabilizing block 8, the extension sleeve rod 9, and the extension rod 11 can be disassembled. This operation allows for quick replacement of extension sleeve rods 9 and extension rods 11 of different lengths, meeting the clamping and detection requirements of the lower clamping block 5 and the upper clamping block 4 with a larger gap, and improving the applicability of the equipment.

[0025] At this time, a first auxiliary groove 14 is provided inside the sleeve block 13, and a pressing block 15 is movably arranged inside the first auxiliary groove 14. A second auxiliary groove 17 is provided inside the insertion rod 12, and a limiting block 18 is movably arranged inside the second auxiliary groove 17. The limiting block 18 passes through the second auxiliary groove 17 and is inserted into the first auxiliary groove 14. Under normal conditions, the insertion of the limiting block 18 into the first auxiliary groove 14 maintains the fixed effect of the sleeve block 13 on the insertion rod 12. However, by pressing the pressing block 15, the pressing block 15 is driven to squeeze the limiting block 18, which eventually causes the limiting block 18 to disengage from the first auxiliary groove 14. This releases the limiting structure between the insertion rod 12 and the sleeve block 13. The above operation does not affect the normal operation of the rotating handle 6 and the first stabilizing block 8. By controlling the disengagement of the sleeve block 13 from the insertion rod 12, the first stabilizing block 8 can be quickly disassembled, which improves the applicability of the equipment and ensures its normal use.

[0026] Next, a first spring 16 is provided inside the first auxiliary groove 14, and the first spring 16 is wound around the outside of the pressing block 15. A second spring 19 is provided inside the second auxiliary groove 17, with one end of the second spring 19 fixedly connected to the inner wall of the second auxiliary groove 17 and the other end of the second spring 19 fixedly connected to the limiting block 18. The elastic properties of the first spring 16 and the second spring 19 drive the limiting block 18 and the pressing block 15 to reset under the influence of non-external force, so that the structure of pressing the pressing block 15 to release the fixing of the insert rod 12 to the sleeve block 13 can be repeatedly operated, making the structure reusable.

[0027] Finally, the first auxiliary groove 14, the pressing block 15, the first spring 16, the second auxiliary groove 17, the limiting block 18, and the second spring 19 are all symmetrically arranged inside the sleeve block 13 and the insertion rod 12; the insertion of the first auxiliary groove 14 by the limiting block 18 has symmetrical stability, which ensures the stability under the limiting and fixing.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
