Description

Technical Field

[0001] The present invention relates to the technical field of corrosion resistance detection, and in particular to an intelligent corrosion resistance detection device for plastic products. Background Technique

[0002] There are significant technical defects and safety hazards in the corrosion resistance detection of plastic products that need to be improved urgently. The current detection process uses a test method of spraying corrosive liquid on one side, which not only makes it difficult to truly simulate the multi-directional corrosion contact scenario in the actual use environment of the product, resulting in systematic deviation between the detection data and the actual performance, but also exposes the detection personnel to volatile corrosive media for a long time due to manual close operation, with the dual occupational risks of respiratory system damage and skin burns. This detection mode based on two-dimensional corrosion contact cannot fully reflect the corrosion resistance characteristics of three-dimensional structural parts. Especially for injection molded parts with complex curved surfaces or internal cavities, it is difficult to effectively evaluate the true corrosion resistance of the stress concentration parts through single-sided testing, directly affecting the engineering guiding value of the detection results.

A box 1003 is slidably connected to the upper surface of the lower plate 1001, and a pull handle 1004 is fixedly connected to the front of the box 1003.

[0041] The working principle and usage process of the present invention: First, the four corners of the bottom of the detection box 1 are fixedly connected with support legs 2. Through the support legs 2, the detection box 1 can be supported and lifted. The front of the detection box 1 is hinged with a box cover 3 through a hinge, which effectively realizes the enclosure of the detection box 1. And the magnet 51 supported on the fixing strip 5 fixed on the side of the detection box 1 can be magnetically connected with the iron plate 4, which effectively realizes that the detection box 1 can present a closed environment. When the box cover 3 needs to be opened, just pull the iron plate 4 to drive the box cover 3 to move.

[0042] Through the provided corrosion mechanism 6, the packing box 61 in the corrosion mechanism 6 is fixedly connected to the outer wall of the top of the detection box 1. Since the inner wall of the hopper cover 63 is threadedly connected to the outer wall of the top of the liquid inlet hopper 62, it is convenient to drive the hopper cover 63 to open through the fixing block 64. After the hopper cover 63 is opened, it is convenient to pour the corrosive liquid from the liquid inlet hopper 62 into the inside of the packing box 61. At the same time, a plurality of spray heads 65 are fixedly connected to the bottom of the packing box 61. Then, the corrosive liquid is sprayed into the inside of the detection box 1 through the spray heads 65. By placing the plastic products for detection inside the detection box 1, it is convenient to perform corrosion detection on the plastic products.

[0043] Through the provided stamping mechanism 7, the driving motor 71 in the stamping mechanism 7 is fixedly connected to the top outer wall of the packing case 61. By connecting the driving motor 71 to the power supply and starting it, the top output shaft of the driving motor 71 can drive the rotation of the turntable 72. Through the turntable 72, the fixed rod 73 can be driven to rotate in a circle with the center point of the turntable 72, thereby facilitating the pulling of the movable rod 74. By pulling the movable rod 74, the fixed frame 75 can be pulled. Through the fixed frame 75, the sliding rod 76 can be pulled. Since the inflatable box 77 is fixed to the top outer wall of the packing case 61, and the inflatable box 77 can support the limiting plate 78, and the limiting plate 78 can limit the sliding rod 76. At the same time, one end of the sliding rod 76 located inside the inflatable box 77 is fixedly connected to the first piston 710. Therefore, when the fixed rod 73 is pulled, the fixed frame 75 can move reciprocally left and right. When the first piston 710 moves to the side away from the limiting plate 78, the inside of the inflatable box 77 will be squeezed. Therefore, the one-way valve on the connecting pipe 79 opens, and at the same time, the one-way valve on the air extraction pipe 711 closes. Therefore, it is convenient to squeeze the gas inside the inflatable box 77 into the inside of the connecting pipe 79, and then it is convenient to inject air pressure into the inside of the packing case 61. Therefore, the corrosive liquid inside the packing case 61 will be sprayed from the nozzle 65 inside the detection box 1, avoiding the problem that the nozzle 65 cannot spray the corrosive liquid without pressure. On the contrary, when the first piston 710 moves to the side close to the limiting plate 78, the one-way valve inside the connecting pipe 79 closes, and the one-way valve inside the air extraction pipe 711 opens. Therefore, it is convenient for the inflatable box 77 to extract external air into the inside of the inflatable box 77. Since the outer wall of the air extraction pipe 711 is threadedly connected to the inner wall of the filter sleeve 712, and the filter sleeve 712 is provided with air-permeable holes arranged in an annular equidistant array on the side away from the air extraction pipe 711, and a sponge 714 is placed inside the filter sleeve 712, the air entering the inside of the inflatable box 77 is effectively filtered, avoiding the problem of dust and the like entering;

[0044] Through the provided drainage mechanism 8, the first guiding block 81 and the second guiding block 82 in the drainage mechanism 8 are respectively fixedly connected to the bottom inner wall of the detection box 1. And through the through groove opened between the mutually approaching sides of the first guiding block 81 and the second guiding block 82, the corrosive liquid inside the detection box 1 can be effectively made to flow downward through the middle through groove, and in cooperation with the second guiding block 82, the corrosive liquid can be blocked, avoiding the problem of flowing out from the front of the bottom of the detection box 1;

[0045] Through the provided flipping mechanism 9, the support box 92 can support the transmission rod 91. Since the output shaft of the driving motor 71 is connected to one end of the transmission rod 91 through bevel gear transmission, when the driving motor 71 is powered on and rotates, it can drive the rotation of the transmission rod 91. At the same time, since the outer wall of the transmission rod 91 is in transmission connection with the outer wall of the limiting rod 98 and the transmission ratio is 1:5, when the transmission rod 91 drives the limiting rod 98 to rotate, the rotation speed of the limiting rod 98 can be slowed down. Since the outer wall of the limiting rod 98 is slidably connected to the inner wall of the sleeve 99 and both the outer wall of the limiting rod 98 and the inner wall of the sleeve 99 are polygonal, it effectively realizes that the limiting rod 98 can drive the rotation of the sleeve 99. By placing the plastic product to be detected between the first clamping frame 910 and the second clamping frame 912, and the second clamping frame 912 is connected by the rotating rod 911, the rotating rod 911 also facilitates the rotation of the second clamping frame 912. Thus, when the spray head 65 sprays the corrosive liquid on the plastic product, the corrosive liquid can be sprayed comprehensively on the plastic product, increasing the corrosion effect and facilitating better detection:

[0046] The mounting frame 914 in the flipping mechanism 9 facilitates the fixed installation of the hydraulic cylinder 915 on the outer wall of the back of the detection box 1. By controlling the telescopic movement of the output shaft of the hydraulic cylinder 915, when the output shaft of the hydraulic cylinder 915 extends, since the output shaft of the hydraulic cylinder 915 can press the third piston 918 downward, the third piston 918 will squeeze the air inside the air box 913. Therefore, it is delivered to the inside of the fixed box 95 through the air delivery pipe 916. And since the four fixed boxes 95 are all connected through the connecting air pipes 921, it is convenient for the pressure inside the fixed box 95 to increase, and then the second piston 97 on the inner wall of each fixed box 95 will be pushed. Therefore, the second piston 97 will push the push rod 96, and the push rod 96 can push the sliding plate 94. Since the inside of the sliding plate 94 is connected to the outer wall of the sleeve 99 through a bearing, it effectively realizes that the sleeve 99 will be driven to move the first clamping frame 910 towards the second clamping frame 912, so it is convenient to clamp the plastic product, avoiding the situation of dropping when flipping the plastic product, and it can be used for the corrosion resistance detection of plastic products of various lengths. After the detection, the output shaft of the hydraulic cylinder 915 is retracted, and then the first clamping frame 910 is effectively moved away from the second clamping frame 912, so it is convenient to remove the clamped plastic product. At the same time, when the third piston 918 moves up and down, since both sides of the bottom of the third piston 918 are fixedly connected with the support rods 919, and roller 920 is sleeved on one side of the two support rods 919 close to the detection box 1, it is convenient for the roller 920 to roll on the inner walls on both sides of the detection box 1. Therefore, the problem of the third piston 918 tilting is avoided;

[0047] Through the provided recycling mechanism 10, since lower plates 1001 are fixedly connected to the inner walls of the four support legs 2, and rear baffles 1002 are fixedly connected to the backs of the lower plates 1001, and at the same time, packing boxes 1003 are placed on the tops of the lower plates 1001, and pull handles 1004 are fixedly connected to the fronts of the packing boxes 1003, the corrosive liquid after being used up inside the detection box 1 will fall into the interiors of the packing boxes 1003, and pulling the packing boxes 1003 through the pull handles 1004 facilitates taking out the packing boxes 1003.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
