Description

Technical Field

[0001] This utility model belongs to the field of hardness testing technology, and specifically relates to a hardness testing device for the production of thermoplastic vulcanized rubber. Background Technology

[0002] Existing hardness testing devices for thermoplastic vulcanized rubber production have significant drawbacks in that they cannot perform testing at multiple locations on the rubber sample. This is mainly reflected in insufficient representativeness of the test results and limitations in product quality control. Because hardness testing is limited to a single location, it cannot comprehensively reflect the overall hardness distribution of the rubber sample, easily overlooking localized areas of abnormal hardness, leading to misjudgments or missed detections.

[0003] Conventional methods typically involve manually performing repeated tests on different parts of the sample, or cutting the sample into multiple small pieces for separate testing. However, these methods are not only inefficient but also susceptible to errors due to variations in human operation. Furthermore, cutting the sample can damage its integrity, affecting subsequent performance testing. Therefore, we aim to design a hardness testing device with a novel structure to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hardness testing device for the production of thermoplastic vulcanized rubber, and to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a hardness testing device for thermoplastic vulcanized rubber production, comprising: a base, an movable component for placing rubber samples is movably installed on the upper side of the base, the base includes a fixed frame, an adjusting component is installed on the upper side of the fixed frame, a lifting component is installed on the upper side of the fixed frame, and a testing component for testing rubber is fixed on the top of the fixed frame; The active component includes a mounting base with two guide rods on the upper side for guiding, and a sample holder for placing samples on the lower side of the mounting base.

[0006] In a preferred embodiment, the adjusting component includes an air cylinder, the front side of which is threadedly connected to a crank handle for driving the air cylinder plug inside the air cylinder, the rear side of which is fixed to the lower left side of the fixed base, and the rear end of which is provided with an air pipe for conveying gas.

[0007] In a preferred embodiment, the lifting component includes an air cylinder two, on the upper side of which a piston is movably mounted, and a top pressure rod is provided on the upper side of the piston. A rubber block is provided on the top of the top pressure rod for anti-collision. In actual use, the adjusting component continuously supplies air into the air cylinder two through the air pipe on its rear side, thereby causing the piston inside the air cylinder two to rise continuously, which in turn drives the top pressure rod to press against the mounting seat, ultimately causing the sample seat with the sample mounted to rise and approach the hardness tester. The hardness tester mentioned above can be selected from existing products on the market as needed, as long as it meets the requirements for hardness testing of rubber products.

[0008] In a preferred embodiment, a shock-absorbing pad is fixed to the front and rear sides of the lower end of the testing piece, and a mounting plate is movably mounted on the two shock-absorbing pads. A hardness tester is fixed in the middle of the mounting plate.

[0009] In a preferred embodiment, the mounting base includes a rotating shaft, and a sample holder is disposed on the upper side of the rotating shaft. The sample holder includes a rotating shaft, and a placement plate is disposed on the upper side of the rotating shaft. The upper surface of the placement plate is recessed downward to form a sample groove for placing a rubber sample.

[0010] In a preferred embodiment, a rotating cylinder for mounting a sample holder is provided in the middle of the upper side of the mounting base, and the upper side of the rotating cylinder is movably connected to the rotating shaft via a screw and a knob.

[0011] In a preferred embodiment, the front, rear, left, and rear sides of the placement plate are each threaded with a screw knob for fixing the sample. The axis of the placement plate is not collinear with the axis of the hardness tester. In actual use, the axis of the hardness tester is deflected to the middle position of any radius after the placement plate is rotated. In this way, the sample detection position can be changed simply by rotating the placement plate, thereby achieving the purpose of multi-position detection.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are: 1. By setting up lifting and adjusting components, the rise of the mounting base causes the sample holder to rise accordingly, and finally the sample holder with the sample installed rises close to the hardness tester, thereby realizing the hardness test of the sample.

[0013] 2. By setting up a mounting base and a sample holder, and in conjunction with a hardness tester with a deflection setting, after the hardness tester performs a hardness test on the sample installed inside the sample holder, the user can loosen the screw knob and rotate the sample holder. The sample holder can be rotated clockwise or counterclockwise. Rotating the sample allows for hardness testing at different locations on the sample, solving the problem that cutting the sample into multiple small pieces for separate testing would damage its integrity and affect subsequent performance testing.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As the first embodiment of this utility model: Please see Figures 1 to 4A hardness testing device for thermoplastic vulcanized rubber production includes: a base 100, an active component 200 for placing rubber samples is movably mounted on the upper side of the base 100, the base 100 includes a fixed frame 110, an adjusting component 120 is mounted on the upper side of the fixed frame 110, a lifting component 130 is mounted on the upper side of the fixed frame 110, and a testing component 140 for testing the rubber is fixed on the top of the fixed frame 110. The active component 200 includes a mounting base 210, with two guide rods on the upper side of the mounting base 210 for guiding, and a sample holder 220 for placing samples on the lower side of the mounting base 210.

[0022] The adjusting component 120 includes an air cylinder 122. The front side of the air cylinder 122 is threadedly connected to a crank handle 121 for driving the air cylinder plug inside the air cylinder 122. The rear side of the air cylinder 122 is fixed to the lower left side of the fixed base. The rear end of the air cylinder 122 is provided with an air pipe 123 for conveying gas.

[0023] The lifting component 130 includes an air cylinder 133, on the upper side of which a piston 132 is movably mounted. A top pressure rod 131 is provided on the upper side of the piston 132. A rubber block is provided on the top of the top pressure rod 131 for anti-collision. In actual use, the adjusting component 120 continuously supplies air into the air cylinder 133 through the air pipe 123 on its rear side, thereby causing the piston 132 inside the air cylinder 133 to rise continuously. This, in turn, drives the top pressure rod 131 to press against the mounting base 210, ultimately causing the sample holder 220, on which the sample is mounted, to rise and approach the hardness tester 141. The hardness tester 141 can be selected from existing products on the market as needed, as long as it meets the requirements for hardness testing of rubber products.

[0024] Specifically, by setting up the lifting component 130 and the adjusting component 120, in actual use, if it is necessary to raise the movable component 200 for sample testing, the user turns the handle 121 to push the air cylinder plug located inside the first air cylinder 122, thereby compressing the air inside the first air cylinder 122 backward and delivering it to the second air cylinder 133 of the lifting component 130 under the action of the air pipe 123. This causes the piston 132 inside the second air cylinder 133 to rise continuously, thereby driving the top pressure rod 131 to press against the mounting base 210. Since the sample seat 220 is installed on the upper side of the mounting base 210, the rise of the mounting base 210 causes the sample seat 220 to rise accordingly, and finally the sample seat 220 with the sample installed rises close to the hardness tester 141, thereby realizing the hardness test of the sample.

[0025] As a second embodiment of this utility model: Please see Figures 1 to 4 A shock-absorbing pad 142 is fixed to the front and rear sides of the lower end of the test piece 140, and a mounting plate is movably installed through the two shock-absorbing pads. A hardness tester 141 is fixed in the middle of the mounting plate.

[0026] Mounting base 210 includes a rotating shaft 221, and a sample holder 220 is provided on the upper side of the rotating shaft 221. The sample holder 220 includes a rotating shaft 221, and a placement plate 222 is provided on the upper side of the rotating shaft 221. The upper surface of the placement plate 222 is recessed downward to form a sample groove for placing rubber samples.

[0027] A rotating cylinder 211 for mounting the sample holder 220 is provided in the middle of the upper side of the mounting base 210. The upper side of the rotating cylinder 211 is movably connected to the rotating shaft 221 by a screw and a knob.

[0028] The front, rear, left and rear sides of the placement plate 222 are each threaded with a screw knob 223 for fixing the sample. The axis of the placement plate 222 is not collinear with the axis of the hardness tester 141. In actual use, the axis of the hardness tester 141 is deflected to the middle position of any radius after the placement plate 222 is rotated. In this way, the sample detection position can be changed by simply rotating the placement plate 222, thereby achieving the purpose of multi-position detection.

[0029] Based on the first embodiment described above, further, by setting the mounting base 210 and the sample holder 220, and cooperating with the deflected hardness tester 141, in actual use, the axis of the placement disk 222 is not collinear with the axis of the hardness tester 141, and the axis of the hardness tester 141 is deflected to the middle position of any radius after the placement disk 222 is rotated. After the hardness tester 141 performs a hardness test on the sample installed inside the sample holder 220, the user can loosen the screw knob and rotate the sample holder 220. The sample holder 220 can be rotated clockwise or counterclockwise to rotate and test the sample. Hardness tests can be performed on different positions of the sample, which solves the problem that cutting the sample into multiple small pieces for separate testing will damage its integrity and affect subsequent performance tests.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
