Detailed Implementation

[0023] 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.

[0024] Reference Figures 1-2 An embodiment of this utility model provides a plastic particle strength testing device, including a testing chamber 1, which supports the device. A moving module 2 is provided on the upper side of the top of the testing chamber 1, which performs dynamic shaping on the device. A positioning column 3 is fixedly installed at the center of the upper surface of the moving module 2, which performs fixed-point installation on the device. An auxiliary component 6 is provided inside the moving module 2, and a testing component 5 is provided on the lower surface of the moving module 2.

[0025] Reference Figures 1-3 The plastic particles to be tested are placed in the testing chamber 1. By pressing down the moving module 2, the testing component 5 is started. The testing component 5 includes a testing plate 51, which is detachably connected to the lower surface of the moving module 2. A pressure sensor 53 is fixedly installed at the axis of the lower surface of the testing plate 51. The downward movement of the pressure testing rod 54, in conjunction with the pressure sensor 53, enables the detection of the strength data of the plastic particles. Pressure testing rods 54 are fixedly installed at both the front and rear ends of the lower surface of the testing plate 51 near the pressure sensor 53. Slider 55 is fixedly connected to the left and right surfaces of the moving module 2. The testing component 5 and the moving module 2 can be quickly disassembled and assembled by fixing bolts and the testing plate 51, which improves the convenience of equipment maintenance and adjustment. Laser indicators 52 are detachably connected to both the front and rear ends of the lower surface of the testing plate 51. The laser indicators 52 are used to calibrate the position of the plastic particles, avoiding the phenomenon of displacement of plastic particles during pressure testing and causing strength testing errors, thus improving the accuracy of the equipment in detecting the strength of plastic particles.

[0026] Reference Figures 2-4 During the process of the moving module 2 pressing down to drive the detection component 5, the auxiliary component 6 is activated. The auxiliary component 6 includes an auxiliary plate 61, which is detachably connected to the inside of the moving module 2. The lower surface of the auxiliary plate 61 is in contact with the lower surface of the inner wall of the moving module 2. Through the insertion of the insert block 67, the auxiliary plate 61 is squeezed upward, causing the auxiliary plate 61 to compress the spring 66, thus achieving elastic compression of the spring 66. This causes the auxiliary rod 64 to move upward and pass through the auxiliary sleeve 65. A fixing post 63 is slidably connected to the upper surface of the auxiliary plate 61. The outer wall of the fixing post 63 is sleeved with the spring 66. The top end of the spring 66 is fixedly connected to the upper surface of the inner wall of the moving module 2, and the bottom end of the spring 66 is fixedly connected to the upper surface of the auxiliary plate 61. The auxiliary sleeve 65 wraps around the auxiliary rod 64, thus compressing the plastic on the auxiliary rod 64. The particles are discharged to avoid adsorption of plastic particles during the equipment reset process, ensuring the cleanliness of the working surface of the detection component 5 and preventing errors caused by plastic particle adsorption when the equipment performs multiple strength tests on plastic particles. Multiple sets of evenly distributed auxiliary rods 64 are fixedly connected to the lower surface of the auxiliary plate 61. Slots 62 are opened at both ends of the lower surface of the moving module 2. Insert blocks 67 are fixedly connected to both ends of the upper surface of the detection chamber 1. The insert blocks 67 are connected through the inner wall of the slots 62. Limiting rods 4 are fixedly connected to both sides of the upper surface of the detection chamber 1 near the insert blocks 67. An auxiliary sleeve 65 is connected through the outer wall of the auxiliary rod 64. The auxiliary sleeve 65 is fixedly connected to the lower surface hole groove of the moving module 2, which enhances the accuracy of the data when the equipment tests the strength of plastic particles.

[0027] Working principle: The plastic particles to be tested are placed in the testing chamber 1. Pressing down the moving module 2 activates the testing component 5. The downward movement of the pressure testing rod 54, in conjunction with the pressure sensor 53, detects the strength of the plastic particles. A laser indicator 52 calibrates the position of the plastic particles, preventing displacement during pressure testing and thus improving the accuracy of strength testing. The fixing bolts and testing plate 51 allow for quick assembly and disassembly of the testing component 5 and the moving module 2, improving the convenience of equipment maintenance and adjustment. The downward movement of the moving module 2 activates the testing component 5... During the testing process, auxiliary component 6 is activated. Through the insertion of insert block 67, auxiliary plate 61 is squeezed upward, causing auxiliary plate 61 to compress spring 66. This elastic compression of spring 66 causes auxiliary rod 64 to move upward and pass through auxiliary sleeve 65. The auxiliary sleeve 65 wraps around auxiliary rod 64, discharging plastic particles from it. This prevents the adsorption of plastic particles during the equipment's reset process, ensuring the cleanliness of the working surface of testing component 5. It also prevents errors caused by plastic particle adsorption during multiple strength tests of plastic particles, thus enhancing the accuracy of the data obtained from plastic particle strength testing.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
