Description

Technical Field

[0001] This utility model relates to the technical field of aging testing devices, specifically a device for testing the resistance strength of aging-resistant conductive rubber. Background Technology

[0002] Existing aging test chambers for materials such as rubber, plastics, and PVC typically consist of an insulated chamber, an air inlet on one side wall, a fan to draw in outside air, a heating element to heat the incoming air to the aging test temperature, and a turntable inside the chamber driven by a motor via a mechanical transmission mechanism. The method of use involves placing the material to be tested on the turntable, then starting the fan and motor. Outside air enters the chamber through the air inlet and is heated by the heating element to reach the required aging test temperature. Simultaneously, the turntable rotates slowly via the mechanical transmission mechanism, and the material continuously absorbs heat from the air inside the chamber to reach and maintain the test temperature, allowing for observation of aging changes.

[0003] However, the existing rubber heat aging test equipment has the following drawbacks during use: the internal space of the chamber is large, and when testing small batches of rubber products, the entire internal cavity of the chamber needs to be heated, resulting in high energy consumption. At the same time, the existing test chamber can only test multiple rubber products under one temperature environment, resulting in low testing efficiency. Therefore, there is room for improvement. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: an aging-resistant conductive rubber resistance strength testing device, comprising: a base and multiple testing mechanisms installed on the base, wherein the testing mechanism includes an insulation shell fixed to the top of the base, a bracket installed on the inner wall of the insulation shell, a rotating shaft rotatably installed on the bracket, a placement rack fixed in a ring array on the rotating shaft, an electric heating wire fixed on the inner wall of the insulation shell, a high-speed fan fixed on the inner wall of the insulation shell, a connecting pipe connecting the top and bottom of the inner cavity of the insulation shell, a sealing door hinged to the insulation shell, and a control panel installed on the outer surface of the insulation shell.

[0006] In a preferred embodiment, the present invention can be further configured such that the support includes support rods fixed in a ring array on the inner wall of the insulation shell and bearings fixed on the ends of the support rods.

[0007] In a preferred embodiment, the present invention can be further configured such that the rotating shaft includes a rotating shaft fixed on the inner ring of the bearing and a fan blade fixed on the top of the rotating shaft.

[0008] In a preferred embodiment, the present invention can be further configured such that the placement frame includes a U-shaped frame symmetrically fixed on a rotating shaft and a plurality of limiting rods connected to the U-shaped frame.

[0009] In a preferred embodiment, the present invention can be further configured such that a temperature sensor is installed on the sealing door and extends into the inner cavity of the insulation shell.

[0010] In a preferred embodiment, the present invention can be further configured such that the output terminal of the control panel is electrically connected to the input terminal of the heating wire and the high-speed fan via wires.

[0011] In a preferred embodiment, the present invention can be further configured such that the output terminal of the temperature sensor is electrically connected to the input terminal of the control panel via a wire.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1. In this utility model, multiple testing mechanisms are installed on the base, and each testing mechanism is set independently. Through the above setting, different rubber products can be tested simultaneously under different temperature conditions, which effectively improves the testing efficiency. In addition, the heat insulation shell in the testing mechanism is reduced in size, and components such as heating wires and high-speed fans are fixed on the inner wall of the heat insulation shell. Through the above setting, the internal cavity of the heat insulation shell is reduced, thereby reducing the energy consumption for heating the heat insulation shell during testing, improving thermal efficiency, and increasing practicality.

[0014] 2. In this utility model, a bracket is installed on the inner wall of the insulation shell, and a rotating shaft is rotatably installed on the bracket. The rotating shaft consists of a shaft and fan blades. The placement rack is fixed on the rotating shaft. Through the above arrangement, the high-speed fan accelerates the air and blows it towards the upper part of the inner cavity of the insulation shell. When the high-speed airflow passes through, it drives the fan blades to rotate. The rotation of the fan blades drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the placement rack to rotate, thereby driving the rubber product placed on the placement rack to rotate. This makes the rubber product heated evenly, avoids the trouble of using a separate drive device to drive the placement rack to rotate, simplifies the structure of the test box, and further reduces the energy consumption of the test box.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0024] Example 1:

[0025] Combination Figure 1-4 As shown, this embodiment provides an aging-resistant conductive rubber endurance strength testing device, including: a base 100 and a plurality of testing mechanisms 200 mounted on the base 100.

[0026] The base 100 is equipped with multiple testing mechanisms 200. This setup allows users to simultaneously conduct thermal aging tests on multiple rubber products under different temperature conditions, effectively increasing testing efficiency.

[0027] The testing mechanism 200 is used to perform heat aging tests on rubber products. It includes an insulation shell 210 fixed to the top of the base 100, a bracket 220 installed on the inner wall of the insulation shell 210, a rotating shaft 230 rotatably installed on the bracket 220, a placement rack 240 fixed in a ring array on the rotating shaft 230, an electric heating wire 250 fixed on the inner wall of the insulation shell 210, a high-speed fan 260 fixed on the inner wall of the insulation shell 210, a connecting pipe 270 connecting the top and bottom of the inner cavity of the insulation shell 210, a sealing door 280 hinged to the insulation shell 210, and a control panel 290 installed on the outer surface of the insulation shell 210.

[0028] The thermal insulation shell 210 is cylindrical and fixed on the base 100. It is made of thermal insulation material to prevent the heat inside the thermal insulation shell 210 from dissipating to the external environment during testing. At the same time, compared with the existing aging test chamber, the internal space of the thermal insulation shell 210 is small, which can effectively reduce the energy consumption of the internal heating of the thermal insulation shell 210 during testing and improve thermal efficiency.

[0029] The bracket 220 is used to install the rotating shaft 230, including support rods 221 fixed in a ring array on the inner wall of the insulation shell 210 and bearings 222 fixed on the end of the support rods 221. The support rods 221 are used to fix the bearings 222. The outer ring of the bearings 222 is fixed on the support rods 221, and the inner ring is used to install the rotating shaft 230 to ensure the stability of the rotating shaft 230 when it rotates.

[0030] The rotating shaft 230 includes a rotating shaft 231 fixed on the inner ring of the bearing 222 and a fan blade 232 fixed on the top of the rotating shaft 231. The rotating shaft 231 is used to mount the fan blade 232 and the placement frame 240. With the fan blade 232, when the airflow passes through the fan blade 232 from bottom to top, it drives the fan blade 232 to rotate. The rotation of the fan blade 232 drives the rotating shaft 231 to rotate. The rotation of the rotating shaft 231 drives the placement frame 240 to rotate, thereby driving the rubber product fitted on the placement frame 240 to rotate, so that the rubber product is heated evenly. In addition, this setting avoids the trouble of using a separate drive device to drive the placement frame 240 to rotate, simplifying the structure of the test box.

[0031] The placement rack 240 is used to place rubber products and includes a U-shaped frame 241 symmetrically fixed on the rotating shaft 231 and a plurality of limiting rods 242 connected to the U-shaped frame 241. The U-shaped frame 241 can limit the two ends of the rubber product, and the limiting rods 242 prevent the rubber product from bending and detaching from the U-shaped frame 241 due to heat during testing.

[0032] The air collection pipe is used to introduce air from the top of the inner cavity of the insulation shell 210 into the connecting pipe 270. The connecting pipe 270 can send the hot air from the top of the inner cavity of the insulation shell 210 back into the bottom of the inner cavity of the insulation shell 210 to form an air circulation.

[0033] The sealing door 280 is used to control the opening and closing of the insulation shell 210. A temperature sensor 281 is installed on the sealing door 280 and extends into the inner cavity of the insulation shell 210 to monitor the temperature of the inner cavity of the insulation shell 210 in real time.

[0034] The control panel 290 is used to set the ambient temperature of the inner cavity of the insulation shell 210 and the test time.

[0035] The working principle and usage process of this utility model are as follows: In use, open the sealing door 280, embed the rubber product to be tested into the placement rack 240, close the sealing door 280, and set the heating temperature and testing time through the control panel 290. At this time, the high-speed fan 260 starts, blowing the air from the bottom of the inner cavity of the insulation shell 210 upwards. When passing through the heating wire 250, the heating wire 250 heats the air, forming hot air. The hot air blows upwards from the inner cavity of the shell, heating the rubber product. Simultaneously, the fan blades 232 rotate under the action of the airflow, driving the rotating shaft 231 to rotate. The rotation of the rotating shaft 231 drives the placement rack 240 to rotate, thus rotating the rubber product embedded in the placement rack 240, ensuring uniform heating of the rubber product. Afterwards, the hot air returns to the bottom of the inner cavity of the insulation shell 210 through the connecting pipe 270, forming a circulation.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
