[0002] Rubber is an elastic polymer that can be obtained from the sap of some plants or artificially produced. According to the different ways of making it, rubber can be divided into two categories: synthetic rubber and natural rubber. It has quite a lot of applications and products, such as tires, gaskets, etc. Rubber cultivation is mainly concentrated in Southeast Asia, such as Thailand, Malaysia, and Indonesia. The rubber industry is one of the important basic industries of the national economy. It not only provides people with daily necessities, medical and other light industrial rubber products that are indispensable in daily life, but also provides various rubber production equipment or rubber parts to heavy industries and emerging industries such as mining, transportation, construction, machinery, and electronics.

[0004] Although the above solution solves the problems mentioned in the background technology, it still has the following shortcomings: the rubber tensile testing machine detects the stretched length by a tape measure, but this detection method is prone to errors in the detection process, which in turn causes inaccurate detection of the stretched length.

[0027] For details, please refer to Figure 1 as well as Figure 2 The top outer sides of the two threaded rods 7 are sleeved with a first pulley 13, the outer side of the first pulley 13 is connected with a first belt 14, the side of the first belt 14 away from the first pulley 13 is respectively connected with a second pulley 15 and a third pulley 16, and a pulley motor 17 is arranged above the second pulley 15 and the third pulley 16; the two first belts 14 are connected to the first pulley 13 on one side thereof, and the two first belts 14 are connected to the second pulley 15 and the third pulley 16 on the other side thereof;

[0028] In this embodiment, the pulley motor 17 is started to drive the second pulley 15 and the third pulley 16 below to rotate synchronously, and then the first belts 14 on both sides drive the first pulleys 13 on both sides to rotate, and then the first pulley 13 drives the threaded rod 7 below to rotate, and then drives the threaded block 5 to move up and down, so that the upper and lower positions of the transverse rod 6 and the upper clamp 8 can be changed to cooperate with the lower clamp 12 below to adapt to rubber materials of different sizes for testing.

[0029] For details, please refer to Figure 1 as well as Figure 2 The top of the dynamometer 10 and the bottom of the transverse rod 6 are fixedly installed, and the bottom of the dynamometer 10 is connected to the top of the pull rope 11 through a hook, and the bottom of the pull rope 11 and the top of the base 1 are fixedly installed; a controller 18 is embedded and installed on the base surface of the base 1, and the controller 18 is electrically connected to the dynamometer 10 and the displacement sensor 9 respectively; an alarm 19 is fixedly installed on the outer end of the fixing frame 2 on one side, and the alarm 19 is electrically connected to the controller 18;

[0030] In this embodiment, when the upper clamp 8 pulls the rubber upward, the dynamometer 10 is used to detect the change in tension, and the displacement sensor 9 is used to detect the upward displacement distance, thereby realizing the detection of the stretching distance to achieve the purpose of rubber stretching test.

[0031] For details, please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The upper clamp 8 and the lower clamp 12 include a first clamp plate 20 and a second clamp plate 21. A locking member 22 is connected to the first clamp plate 20, and a clamp plate 23 is connected to one side of the locking member 22.

[0032] In this embodiment, the rotation of the locking member 22 drives the movement of the clamping plate 23 to clamp and fix the rubber material.

[0033] The working process of the utility model is as follows: when the rubber tensile testing machine for rubber production is used, firstly, the pulley motor 17 is started to drive the second pulley 15 and the third pulley 16 below to rotate synchronously, and then the first belts 14 on both sides drive the first pulleys 13 on both sides to rotate, and then the first pulley 13 drives the threaded rod 7 below to rotate, and then drives the threaded block 5 to move up and down, so that the upper and lower positions of the transverse rod 6 and the upper clamp 8 can be changed to cooperate with the lower clamp 12 below to adapt to rubber materials of different sizes for testing, and then the rotation of the locking member 22 drives the movement of the clamping plate 23 to achieve the clamping of the rubber material in the upper and lower positions. It is tightly fixed to facilitate subsequent stretching. Before stretching, the displacement sensor 9 and the dynamometer 10 are cleared. During the stretching process, the upper clamp 8 moves upward slowly. In the process of the upper clamp 8 pulling the rubber upward, the dynamometer 10 is used to detect the change in tension. At the same time, the displacement sensor 9 is used to detect the displacement distance of the upward movement, so as to detect the stretching distance, so as to achieve the purpose of rubber stretching test. When the rubber breaks due to stretching, the tension of the dynamometer 10 changes greatly instantly. At this time, a value is read out by the displacement sensor 9, which is the maximum value of the stretching that the rubber can withstand. At the same time, the upper clamp 8 will stop moving upward.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
