Description

Technical Field

[0001] The utility model relates to the technical field of tension testing machines, in particular to a silicone tension testing machine. Background Art

[0002] Silicone tensile testing machine, also known as electronic tensile testing machine, can be used for tensile and other performance tests of plastic films, composite materials, adhesives, adhesive tapes, stickers, medical patches, protective films, release paper, backing materials, rubber, paper fibers and other products.

[0003] my country's published patent application number is CN201921821397.5, which mentions a silicone tensile testing machine, specifically involving: "a strength testing box, a knob is provided at the left end of the front of the strength testing box, and evenly distributed scales are engraved around the knob. A number of display lights are provided at the right end of the front of the strength testing box, and a number of buttons are provided at the left end of the display light. The left and right ends of the bottom of the strength testing box are fixedly connected with support columns, and the bottom ends of the outside of the support columns are provided with shock-absorbing pads. By setting the display light, the user can judge whether the device is running according to the display light. By setting the shock-absorbing pads, the influence of external vibration on the test results is reduced. By setting the strength detector and the display screen, the strength of the material to be tested can be accurately detected and displayed. By setting the fixed plate, the strength detector can remain stationary to test the material to be tested, thereby simplifying the detection process."

[0004] Although this technology can realize the tensile test of silicone, we found that this technology still has certain defects when simulating its use:

[0005] During specific use, it is necessary to manually turn the twisting rod to close the fastener to clamp the silicone, and it is also necessary to manually loosen it to disassemble the silicone. On the one hand, this method requires more time and physical strength of the staff, and is relatively troublesome to operate. On the other hand, manual tightening for clamping may cause unstable clamping, resulting in the silicone detaching from the clamping part during the tensile test, resulting in the inability to conduct the experiment normally. Therefore, in view of the defects of the above-mentioned prior art, we have specifically designed a silicone tensile testing machine that can achieve automatic clamping and more stable clamping.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 A silicone tensile testing machine comprises a testing machine base 1, a support frame 2, a display 3 installed on the right side of the top of the testing machine base 1 and used to display data, a driving motor 4, a driving screw 5 and a strength detector body 9. The support frame 2 is installed on the top of the testing machine base 1, and a support plate 6 driven by a driving motor 4 is slidably connected between the inner walls of the support frame 2. The support plate 6 is used to drive the mounting plate 8 to move, so as to realize the mutual distance and mutual approach of two clamping frames 10. The top front of the support frame 2 and the front of the support plate 6 are respectively fixed with a mounting plate 7 and a mounting plate 8; the side where the mounting plate 7 and the mounting plate 8 are close to each other is installed with a clamping frame 10, and the strength detector body 9 is installed on the top of the mounting plate 7 and connected to the clamping frame 10 at the bottom of the mounting plate 7; the inner walls of the clamping frame 10 are respectively provided with a clamping plate 11 and a clamping plate 12 driven by a driving motor 1001, and one side of the clamping plate 11 A positioning groove 14 is provided, and clamping teeth 15 are fixed on the inner wall of the positioning groove 14 at equal intervals. A clamping protrusion 13 is integrally formed on one side of the clamping plate 2 and at a position corresponding to the positioning groove 14. A clamping groove is provided on the surface of the clamping protrusion 13. As the clamping protrusion 13 is pressed, the silicone can be bitten with the structural features of multiple clamping grooves and multiple clamping teeth 15, so that the silicone is more stable in the positioning groove 14; a touch rod 601 is also fixed on the right side of the top of the support plate 6, and a limit ring 6011 is fixed on the rod body of the touch rod 601 and near the top, and the limit ring 6011 can limit the movable distance of the touch rod 601. A pressure sensor 18 is installed at the inner top of the support frame 2 and at a position corresponding to the touch rod 601. A controller 201 is installed on the top right side of the support frame 2. The pressure sensor 18 is connected to the controller 201 through a wire, and the controller 201 is connected to the two drive motors 2 1001 through a wire.

[0024] In this embodiment, the power output shaft of the driving motor 2 1001 movably passes through the clamping frame 10 and is connected to a double-threaded rod, on which two opposite threads are provided, and the two opposite threads respectively pass through the clamping plate 1 11 and the clamping plate 2 12. Four limiting rods 16 are also fixed between the inner walls of the clamping frame 10, and the limiting rods 16 movably pass through the clamping plate 1 11 and the clamping plate 2 12.

[0025] Specifically, by starting the driving motor 2 1001, the double-threaded rod can be used to drive the clamping plate 11 and the clamping plate 2 12 to move closer to or away from each other, thereby clamping or loosening the silicone. A limit rod 16 is also provided between the clamping plate 11 and the clamping plate 2 12, which can limit the movement trajectory of the clamping plate 11 and the clamping plate 2 12 to ensure their stability during movement.

[0026] In this embodiment, a sleeve 202 is installed on the inner top wall of the support frame 2 and at a position corresponding to the touch rod 601. The top of the pressure sensor 18 is fixed to the inner top wall of the sleeve 202 through a silicone gasket 17. The inner wall of the sleeve 202 is also connected with a movable plate 19 in a limited sliding manner. A push rod 20 is fixed to the top of the movable plate 19, and a top plate 21 is fixed to the top of the push rod 20. A fixed plate 23 is also fixed on the inner wall of the sleeve 202 and at a position away from the movable plate 19. The push rod 20 movably penetrates the fixed plate 23, and a reset spring 22 is sleeved on the rod body of the push rod 20. The top and bottom of the reset spring 22 are respectively fixed to the fixed plate 23 and the movable plate 19.

[0027] Specifically, when the top of the touch rod 601 contacts the movable plate 19, it can push the top plate 21 upward, thereby using the top plate 21 to apply a pressure signal to the pressure sensor 18. When the touch rod 601 withdraws from the sleeve 202, the movable plate 19 will be rebounded by the return spring 22, thereby moving downward and driving the top plate 21 away from the pressure sensor 18 to ensure the next use.

[0028] In this embodiment, a driving motor 4 is installed on the top of the support frame 2, and the power output shaft of the driving motor 4 movably passes through the support frame 2 and is connected to a driving screw 5. The bottom thread of the driving screw 5 passes through the support plate 6 and is rotatably connected to the top of the testing machine base 1.

[0029] Specifically, by starting the driving motor 4, the driving screw 5 can be driven to rotate, so that the support plate 6 can be raised or lowered in the support frame 2.

[0030] When in use, the staff will place the two ends of the silicone to be tested in the two positioning grooves 14 respectively, and then start the two driving motors 1001. The two driving motors 1001 respectively drive the double-threaded rods connected thereto to rotate. When the double-threaded rods rotate, the clamping plate 11 and the clamping plate 12 in the clamping frame 10 can be driven to approach each other, and the clamping protrusion 13 can enter the positioning groove 14. As the clamping protrusion 13 gradually enters the positioning groove 14, the silicone end placed in the positioning groove 14 can be clamped, and the silicone end can be clamped and fixed by the clamping teeth 15 and the clamping groove;

[0031] When both ends of the silicone rubber are clamped, the driving motor 4 can be started to drive the support plate 6 to move downward. When the support plate 6 moves downward, the two clamping frames 10 can be used to pull the silicone rubber to achieve a tensile test, and the strength detector body 9 can be used to detect the silicone rubber.

[0032] After the test is completed, the two clamping frames 10 need to be brought closer to each other again to realize the disassembly of the silicone. At this time, the touch rod 601 is lifted together with the rise of the support plate 6, and the pulling force of the two clamping frames 10 on the silicone is gradually loosened, so that the silicone is in a relaxed state. When the top of the touch rod 601 enters the sleeve 202, the top of the touch rod 601 squeezes the movable plate 19, and the movable plate 19 pushes the top rod 20, and the top rod 20 pushes the top plate 21 to rise. When the top of the top plate 21 contacts the bottom of the pressure sensor 18, the pressure sensor 18 receives a pressure signal, thereby transmitting the signal to the controller 201, and the two drive motors 2 1001 are started again through the controller 201, thereby realizing the reversal of the double-threaded rod, and making the clamping plate 1 11 and the clamping plate 2 12 move away from each other, thereby loosening the clamping effect on the silicone. At this time, the staff can easily remove the tested silicone.

[0033] It should be noted that the strength detector body 9 in the silicone tensile testing machine is a common testing mechanism in this technical field, and is also mentioned in patent CN201921821397.5, so the working principle and specific structure of the strength detector body 9 are not described in detail in this specification.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
