Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools, and specifically, it is a slitting jig for heat-sealing force value specimens. Background Art

[0002] The heat-sealing force value, also known as the heat-sealing strength or heat-sealing force, is an important index to measure the heat-sealing performance of materials. It refers to the ability to bond two or more layers of thin films together by heating and melting under specific temperature, pressure, and time conditions. The magnitude of the heat-sealing force value directly affects the sealing performance and reliability of the materials. Therefore, in the heat-sealing force value test, it is necessary to ensure the consistency of each test condition to improve the accuracy of the heat-sealing force value. Among them, to ensure the same heat-sealing area, the widths of the two layers of thin films should be kept consistent. If the widths of the thin films are different, it may cause uneven heat-sealing areas, affecting the heat-sealing effect and the accuracy of the test.

[0003] In the current existing technology, the splines used in each test are measured with a steel ruler to obtain the required dimensions, and then manually cut with a craft knife. This method has low efficiency and accuracy in specimen slitting, inconsistent slitting standards for specimens, and it is difficult to ensure the accuracy of the heat-sealing force value test. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a slitting jig for heat-sealing force value specimens, aiming to solve the technical problems existing in the prior art, such as low efficiency and accuracy in specimen slitting, inconsistent slitting standards for specimens, and difficulty in ensuring the accuracy of the heat-sealing force value test.

[0005] To solve the above technical problems, the utility model provides a slitting jig for heat-sealing force value specimens, including: a base, on which a plurality of cutting channels are arranged at intervals; a slitting mechanism, including a moving seat, a tool magazine, and a plurality of blades. The moving seat is slidably arranged on the base, the tool magazine is arranged on the moving seat, and the cutting ends of the plurality of blades pass through the plurality of cutting channels correspondingly.

[0006] The plurality of blades cut along the plurality of cutting channels arranged at intervals, so that the width of each cut spline remains consistent, which is beneficial to unifying the slitting standards of specimens and improving the accuracy of the heat-sealing force value test. At the same time, there is no need to manually measure the width of the required specimens, nor is there a need for additional auxiliary tools to assist in slitting. Only by driving the tool magazine and the plurality of blades along the corresponding plurality of cutting channels through the moving seat can a plurality of specimens be slit, which is beneficial to improving the slitting efficiency and accuracy of specimens and further improving the accuracy of the heat-sealing force value test.

[0007] Preferably, a linear guide rail is arranged on the base, and the moving seat is slidably clamped on the linear guide rail, and the linear guide rail is parallel to the cutting channels.

[0008] The linear guide rail keeps the moving direction of the moving seat consistent, preventing the various strips cut by multiple blades from being inconsistent due to the position deviation generated when the moving seat moves. The linear guide rail is parallel to the cutting path, so that when the moving seat moves, it ensures that multiple blades can move along the directions of the corresponding multiple cutting paths, preventing damage to the blades and causing the paths of multiple blades to deviate, which is conducive to unifying the cutting standard of the specimen and improving the accuracy of the heat seal force value test.

[0009] Preferably, limit members are provided at both ends of the linear guide rail.

[0010] The limit members ensure that the moving seat does not disengage from the linear guide rail, preventing damage to the blades or scratching of the operators caused by the moving seat disengaging from the linear guide rail. At the same time, it keeps the length of each cut strip consistent, which is conducive to improving the stability and safety of the heat seal force value specimen cutting jig.

[0011] Preferably, a locking member is provided on the moving seat. The locking member includes a connecting portion and a knob, and the locking member is detachably connected to the moving seat.

[0012] The locking member can lock the moving seat at a certain position on the linear guide rail, preventing the moving seat from sliding when the heat seal force value specimen cutting jig is moved, which may cause damage to the blades or scratching of the operators, and is conducive to improving the safety of the heat seal force value specimen cutting jig.

[0013] Preferably, the connecting portion is in threaded fit connection with the moving seat, and the connecting portion can pass through the moving seat and abut against the linear guide rail.

[0014] The threaded fit connection enables the locking member to adjust the depth of screwing into the moving seat, thereby adjusting the magnitude of the relative acting force between the moving seat and the linear guide rail, preventing the moving seat from moving along the linear guide rail under different degrees of external interference, which may cause damage to the blades or scratching of the operators, and is conducive to further improving the safety of the heat seal force value specimen cutting jig.

[0015] Preferably, the knife holder is connected to the moving seat through a connecting member.

[0016] Setting a connecting member between the moving seat and the knife holder can make the structural design of the knife holder and the position setting relative to the cutting path more flexible, which is conducive to improving the expandability of the heat seal force value specimen cutting jig.

[0017] Preferably, the knife holder is rotatably mounted on the connecting member through a rotating rod. The rotating rod passes through the knife holder and multiple blades and is detachably connected to the connecting member.

[0018] The knife box is rotatably connected to the connecting piece. When cutting the sample, the force applied to the knife box can be adjusted so that multiple blades in the knife box can cut samples of different thicknesses, which is beneficial to improving the applicability of the sample cutting fixture for heat sealing force value; at the same time, when the sample cutting fixture for heat sealing force value is not in use, the knife box can be rotated so that the cutting ends of multiple blades do not extend outside the base, which is beneficial to further improving the safety of the sample cutting fixture for heat sealing force value. The detachable connection between the rotating rod and the knife box and multiple blades restricts the positions of the knife box and multiple blades with the axis of the rotating shaft as the axis. When the knife box or the blade is damaged, it can also be replaced after removing the rotating rod, which is beneficial to ensuring the rotational connection of the knife box and facilitating subsequent maintenance.

[0019] Preferably, a limiting portion is provided on the rotating rod, and the limiting portion abuts against the side of the knife box away from the connecting piece.

[0020] The limiting portion cooperates with the connecting piece to prevent the knife box from moving axially along the rotating rod or even detaching from the rotating rod, resulting in the deviation of the moving paths of multiple blades, affecting the unified sample cutting standard, or damaging the blades and scratching the operators, etc. It is beneficial to improve the safety of sample cutting and ensure the unified sample cutting standard.

[0021] Preferably, a plurality of blade receiving grooves are provided at intervals in the knife box, the blades are slidably arranged in the blade receiving grooves, and one end of the blade extends from the notch of the blade receiving groove to the outside of the knife box.

[0022] The plurality of blade receiving grooves can be adapted to a plurality of cutting channels as needed to cut multiple samples at one time, which is beneficial to further improving the cutting efficiency of the samples. When installing and disassembling the blades, the blades can be slid into or out of the blade receiving grooves, which is beneficial to improving the loading and unloading efficiency of the blades. At the same time, the blades can rotate with the knife box, enabling the blades to be normally stressed and cut the samples, which is beneficial to ensuring the normal progress of sample cutting. One end of the blade extends from the notch of the blade receiving groove to the outside of the knife box, ensuring that a certain margin of the cutting end of the blade is left, so that the cutting end can pass through the cutting channel to achieve the cutting of the sample.

[0023] Preferably, the blade receiving grooves are opposite to the cutting channels.

[0024] When the blade extends to the outside of the knife box, the blade receiving grooves and the cutting channels are opposite, so that the blade can directly extend from the notch of the blade receiving groove to the cutting channel. And when the knife box rotates, the blade can extend to the outside of the base to achieve the cutting of the sample, which is beneficial to improving the accuracy of sample cutting and ensuring the unified sample cutting standard.

[0025] Compared with the prior art, the beneficial effects of the present utility model are:

[0026] Multiple blades cut along multiple cutting tracks arranged at intervals, ensuring that the width of each cut spline remains consistent. This is beneficial for unifying the cutting standard of the specimens and improving the accuracy of the heat seal force value test. At the same time, there is no need to manually measure the width of the required specimens, nor are additional auxiliary tools required for cutting. Only by driving the knife holder and multiple blades along the corresponding multiple cutting tracks through the moving seat can multiple specimens be cut, which is conducive to improving the cutting efficiency and accuracy of the specimens and further enhancing the accuracy of the heat seal force value test.

[0036] In addition, the base 10 can also be of a flat type, a groove type and other structures, as long as the blades 24 can slide along the cutting channels 11 and slit the specimens located under the base 10 when the moving seat 21 drives the tool magazine 23 to move.

[0037] In this embodiment, please refer to Figure 1 As shown, a linear guide rail 12 is further provided on the base 10, and the moving seat 21 is slidably clamped on the linear guide rail 12. The linear guide rail 12 is parallel to the cutting channels 11. It can be understood that the linear guide rail 12 is located on one side of the position where the moving seat 21 is located on the "L" - shaped base 10. When the moving seat 21 slides along the linear guide rail 12, the sliding path of the moving seat 21 is also parallel to the cutting channels 11.

[0038] In addition, there can be a plurality of linear guide rails 12, which are distributed at different positions on the base 10. The moving seat 21 is slidably clamped on these linear guide rails 12. When the moving seat 21 slides along the linear guide rails 12, the sliding path of the moving seat 21 is also parallel to the cutting channels 11.

[0039] Specifically, limit members 13 are further provided at both ends of the linear guide rail 12 to limit the sliding distance of the moving seat 21 along the linear guide rail 12, unify the slitting standard of the specimens, and prevent the moving seat 21 from disengaging from the linear guide rail 12.

[0040] In addition, the limiting member 13 can also be arranged near both ends of the linear guide 12 on the base 10, so as to limit the sliding distance of the moving seat 21 along the linear guide 12, unify the cutting standard of the specimen, and prevent the moving seat 21 from disengaging from the linear guide 12.

[0041] In this embodiment, please refer to Figure 1 As shown, a locking member 25 is further provided on the moving seat 21. The locking member 25 includes a connecting portion 252 and a knob 251, and the locking member 25 is detachably connected to the moving seat 21. It can be understood that the locking member 25 can load and unload the connecting portion 252 on the moving seat 21 through the knob 251.

[0042] Specifically, the connecting portion 252 of the locking member 25 is in threaded fit connection with the moving seat 21. After the connecting portion 252 passes through the moving seat 21, it can abut against the linear guide 12. It can be understood that the knob 251 can adjust the screwing depth of the connecting portion 252, and further adjust the locking degree between the linear guide 12 and the moving seat 21 by the locking member 25.

[0043] In this embodiment, please refer to Figure 1 and Figure 2 As shown, a connecting member 22 is provided between the moving seat 21 and the tool magazine 23. One end of the connecting member 22 is connected to the moving seat 21, and the other end extends toward the cutting path 11 and is connected to the tool magazine 23.

[0044] It can be understood that the connecting member 22 makes the tool magazine 23 closer to the cutting path 11, and no matter whether the shape and structure of the base 10 change or the moving seat 21 slides to any position on the base 10, the tool magazine 23 can be close to the cutting path 11, and multiple blades 24 can move along the corresponding multiple cutting paths 11 to cut the specimen. Therefore, the shape and structure of the connecting member 22 can be changed according to the actual situation.

[0045] Specifically, the tool magazine 23 is rotatably mounted on the connecting member 22 through a rotating rod 26. The rotating rod 26 passes through the tool magazine 23 and multiple blades 24 and is detachably connected to the connecting member 22.

[0046] It can be understood that one end of the rotating rod 26 passing through the tool magazine 23 and multiple blades 24 enables the tool magazine 23 and multiple blades 24 to rotate along the axis of the rotating rod 26. When it is necessary to replace the tool magazine 23 or the blades 24, the rotating rod 26 can be disassembled axially along the rotating rod 26, so that the tool magazine 23 and multiple blades 24 are separated from the connecting member 22.

[0047] In addition, the rotating rod 26 can be in bolt fit connection with the connecting member 22.

[0048] More specifically, a limiting portion is provided on the rotating rod 26, and the limiting portion abuts against the side of the tool magazine 23 away from the connecting member 22.

[0050] In addition, between the knife holder 23 and the connecting part 22, a washer or other limiting structures can also be provided to adjust the relative position between the knife holder 23 and the cutting track 11.

[0051] In this embodiment, please refer to Figure 1 and Figure 2 As shown, the knife holder 23 is provided with a plurality of knife receiving grooves 231 at intervals, the blade 24 is slidably arranged in the knife receiving groove 231, and one end of the blade 24 extends from the notch of the knife receiving groove 231 to the outside of the knife holder 23.

[0052] It can be understood that the blade 24 can be slidably inserted and removed in the knife receiving groove 231, and the blade 24 can rotate together with the knife holder 23. When the blade 24 is completely inserted into the knife receiving groove 231, one end of it can extend out of the outside of the knife holder 23 from the notch of the knife receiving groove 231, leaving a certain margin for the blade 24 so that the blade 24 can reach the cutting track 11 and extend out of the outside of the base 10 when rotating with the knife holder 23.

[0053] In addition, the blade 24 can be arranged in multiple knife receiving grooves 231 according to actual needs, and the quantity does not exceed the quantity of the cutting tracks 11.

[0054] Specifically, the knife receiving groove 231 is opposite to the cutting track 11.

[0055] It can be understood that after the blade 24 extends out of the notch of the knife receiving groove 231, due to the knife receiving groove 231 being opposite to the cutting track 11, when the knife holder 23 rotates close to the cutting track 11, the cutting end of the blade 24 can directly extend out of the outside of the base 10 from the cutting track 11 to slit the specimen located below the base 10.

[0056] The specific application process of the present utility model is as follows:

[0057] After the operator lays the specimen flat, screw out the connecting part 252 of the locking part 25 by a certain distance so that the moving seat 21 can move along the linear guide rail 12. Move the moving seat 21 to one end of the linear guide rail 12, place the base 10 of the heat sealing force value specimen slitting jig downward on the specimen, rotate the knife holder 23 until the cutting ends of multiple blades 24 abut against the specimen, apply a force sufficient to slit the specimen to the knife holder 23, and push and pull the moving seat 21 toward the other end of the linear guide rail 12 so that multiple blades 24 slit each specimen along the corresponding multiple cutting tracks 11. Rotate the knife holder 23 until multiple blades 24 retract above the cutting tracks 11, repeat the above steps to obtain multiple specimens, and after completing the specimen slitting, the locking part 25 can be screwed into the moving seat 21 until the connecting part 252 abuts against the linear guide rail 12 to fix the moving seat 21.

[0058] When replacing the blade 24 or the tool magazine 23, remove the rotating rod 26 to disengage the tool magazine 23 from the connecting member 22. Tilt the notch of the blade receiving groove 231 of the tool magazine 23 downward so that the blade 24 to be replaced slides out from the blade receiving groove 231. Then tilt the notch of the blade receiving groove 231 upward and slide the new blade 24 into the blade receiving groove 231. Pass the rotating rod 26 through the tool magazine 23 and multiple blades 24 again and connect it to the connecting member 22, and the replacement of the blade 24 or the tool magazine 23 can be completed.

[0059] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
