Detailed implementation manners

[0024] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following further elaborates on the present utility model in conjunction with specific embodiments.

[0025] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the present utility model should have the ordinary meanings understood by those with ordinary skills in the field to which the present utility model belongs.

Words such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0026] Such as Figures 1 to 5As shown in the figure, a detection device for plastic polymer products includes: a bottom plate 1, side plates 2, two clamping components, and a measuring component. The side plates 2 are movably connected above the bottom plate 1;

[0027] Furthermore, as Figure 2 , Figure 3 and Figure 5 shown, the clamping component is fixedly connected to one side of the side plate 2 and is used to clamp and stabilize the plastic polymer product, providing a fixed basis for subsequent hardness measurement work. It includes a mounting plate 6. The mounting plate 6 is fixedly connected to one side of the side plate 2. Two half gears 7 are rotatably connected above the mounting plate 6. One side of the half gear 7 is rotatably connected to a first movable rod 8. One side of the first movable rod 8 is rotatably connected to two second movable rods 9. The other ends of the two second movable rods 9 are rotatably connected to the mounting plate 6. The end of the first movable rod 8 away from the half gear 7 is rotatably connected to a limit clamp 10. An anti-slip pad 11 is fixedly connected to the inner ring of the limit clamp 10. A second groove 17 is provided on one side of the mounting plate 6. A chute is provided inside the second groove 17. A slide rod 13 is slidably connected in the chute. One end of the slide rod 13 close to the second groove 17 is fixedly connected to a top plate 12. A plurality of first springs 14 are fixedly connected to one side of the top plate 12. The other ends of the first springs 14 are fixed to the bottom of the second groove 17. A connecting rod 15 is fixedly connected above the other end of the slide rod 13. The other end of the connecting rod 15 is rotatably connected to the bottom of one of the half gears 7. A first groove 16 is provided above the mounting plate 6. The connecting rod 15 is slidably arranged inside the first groove 16. Through the limit clamp 10 and the anti-slip pad 11 on its inner ring, the plastic polymer product can be effectively clamped to prevent sliding and displacement. The design of the first movable rod 8 and the second movable rods 9 enables the clamping range and force to be flexibly adjusted to adapt to products of different sizes and shapes. When the device is in use, after placing the workpiece in the middle of the two clamping components, drive the handle 5 to make the two clamping components approach each other. When the workpiece touches the top plate 12, push the slide rod 13 backward, drive the connecting rod 15 backward, drive the half gear 7 to rotate, and thus drive the two limit clamps 10 to close and clamp the workpiece;

[0028] Furthermore, as Figure 1 and Figure 4As shown in the figure, the measuring component is fixedly connected above the middle of the bottom plate 1 and is used to measure the deformation of plastic polymer products and feedback them in digital form. It includes a limit ring 18. The limit ring 18 is fixedly connected above the bottom plate 1. A plurality of through grooves are provided on the limit ring 18. A scale rod 20 is slidably arranged inside the through grooves. One end of the scale rod 20 is fixedly connected with a contact plate 19. On both sides of the scale rod 20 on the contact plate 19, second springs 21 are fixedly connected. The other ends of the second springs 21 are fixed to the limit ring 18. A plurality of contact plates 19 together form an annular arrangement. The contact plates 19 are evenly distributed inside the limit ring 18. The scale rod 20 slides through the through grooves of the limit ring 18, and can accurately measure the deformation of plastic polymer products. A plurality of contact plates 19 are evenly distributed inside the limit ring 18 to ensure uniform force during the measurement process and more accurate results. The design of the second spring 21 enables the contact plate 19 to quickly return to the initial position after measurement, facilitating repeated measurement. The fixed connection between the limit ring 18 and the bottom plate 1 ensures the stability of the measuring component and avoids possible deviations during the measurement process. A plurality of contact plates 19 can simultaneously measure the deformation at different points, improving the comprehensiveness and reliability of the measurement. It is designed to feedback the measurement results in digital form, facilitating reading and recording, and improving the measurement efficiency and accuracy. When the device is in use, through the mutual approach of the two side plates 2 and the clamping component, continuous horizontal pressure is applied to the middle workpiece, thereby driving the workpiece to deform in the middle. At this time, the deformed part contacts the contact plate 19 and pushes the contact plate 19 to move towards the limit ring 18.

[0029] Furthermore, as Figure 4 shown, digital scales (not shown in the figure) are provided on the scale rod 20. The scale rod 20 penetrates the outer wall of the limit ring 18. In the normal state without measurement, the scale rod 20 will not exceed the range of the limit ring 18. When entering the measurement state, the length of the scale rod 20 that exceeds can be directly read.

[0030] Furthermore, as Figure 1 shown, a screw rod 4 is arranged inside the middle of the bottom plate 1. One side side plate 2 is threadedly connected with the screw rod 4, and the other side side plate 2 is rotatably connected with the screw rod 4. One end of the bottom plate 1 is fixedly connected with a fixing plate 3. The screw rod 4 penetrates the outer wall of the bottom plate 1 and is fixedly connected with a handle 5 outside the bottom plate 1. The handle 5 is rotatably connected with the bottom plate 1. By driving the handle 5, the screw rod 4 can be rotated, so as to realize the approach and separation of the side plate 2 on the side away from the handle 5 towards the side plate 2 on the side of the handle 5.

[0031] Furthermore, as Figure 2 shown, both the limit clamp 10 and the anti-slip pad 11 are arc-shaped. At the same time, the anti-slip pad 11 is made of rubber. The annular shape can ensure that the clamping component can adapt to workpieces of various sizes and shapes, and the anti-slip pad 11 can better ensure the stability of workpiece fixation.
