[0002] Plastic profiles are primarily made from rigid PVC, with some using semi-rigid PVC, flexible PVC, and low-foaming polyurethane. They are widely used in window frames, stair railings, cable trays, baseboards, shaped pipes, furniture, and building materials. During the production of plastic profiles, strength testing is necessary to control quality and evaluate material properties to ensure the reliability of subsequent work.

[0003] In the strength testing of plastic profiles, the vertical compressive strength or the horizontal tensile properties can be tested using a cylinder assembly. However, existing methods rely on a single testing tool, reducing the practicality of the testing process and hindering continuous feeding of the plastic profiles, thus lowering the device's efficiency. Therefore, a new plastic profile strength testing device is proposed to address these issues. Utility Model Content

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a plastic profile strength testing device, including an operating table 1, a support frame 2 on the upper surface of the operating table 1, and a first cylinder 3 embedded in the crossbar of the support frame 2. A first pneumatic telescopic arm 4 is provided below the first cylinder 3, and a pressure block 5 is provided at the lower end of the first pneumatic telescopic arm 4. Multiple sets of connecting rods are provided on the support frame 2 at the front and rear of the pressure block 5, and a dust suction port 6 is provided at the lower end of the rear connecting rod. An exhaust pipe is provided on the dust suction port 6, and the other end of the exhaust pipe is connected to an exhaust fan. A sunlight simulator 7 is provided at the lower end of the connecting rod on the front of the pressure block 5, and a wire is provided on the sunlight simulator 7. It should be noted that the other end of the exhaust pipe is connected to a dust collection box through a filter screen, and the sunlight simulator 7 is connected to a power supply and temperature control system through wires.

[0020] Furthermore, under the action of the first cylinder 3, the pressure block 5 forms a vertical lifting structure with the operating table 1 through the first pneumatic telescopic arm 4, thereby performing compression strength testing on the plastic profile through the liftable pressure block 5. And under the action of the exhaust fan, the dust suction port 6 forms a suction structure with the operating table 1 through the exhaust pipe, thereby facilitating the timely extraction and collection of broken plastic fragments during the strength testing process through the inclined dust suction port 6.

[0021] The control panel 1 has a servo motor 8 inside, and one end of the output shaft of the servo motor 8 is connected to a screw 9 via a coupling. A first synchronous pulley is fitted on the screw 9, and a second synchronous pulley is correspondingly provided on one side of the first synchronous pulley. A synchronous belt is fitted on the outer wall of the first and second synchronous pulleys, and a screw 9 is also inserted through the second synchronous pulley. A first slide rod 10 is correspondingly provided on the outer side of the screw 9, and multiple sets of first movable blocks 11 are inserted through the screw 9 and the first slide rod 10. The first movable blocks 11 are positioned on opposite sides. A connecting frame 12 is provided, and the other end of the connecting frame 12 is inserted into the fixed rod 13. A slider is inserted into the upper end face of the fixed rod 13, and a fixed frame 16 is provided above the slider. It should be noted that there is a certain gap between one end of the connecting frame 12 and the movable groove of the fixed rod 13, so as to ensure that the two ends of the fixed rod 13 can rotate synchronously. In addition, the inner wall of the synchronous belt in this device is provided with internal teeth that mesh with the external teeth of the first synchronous pulley and the second synchronous pulley, so as to ensure that the two sets of screws 9 can rotate synchronously.

[0022] Furthermore, the first movable block 11 and the fixed rod 13, under the action of the servo motor 8, form a limiting sliding structure with the operating table 1 through the screw 9 and the first slide rod 10. The screws 9 form a linkage structure through the first synchronous pulley, the second synchronous pulley, and the synchronous belt. Thus, the plastic profile and its limiting components can be moved as a whole through multiple sets of rotating screws 9, so that the two ends of the operating table 1 can load and unload the plastic profile, thereby ensuring the working efficiency of the device.

[0023] The first movable block 11 is provided with a shelf on top, and a second cylinder 14 is embedded in the shelf. The second cylinder 14 is provided with a second pneumatic telescopic arm 15, and the other end of the second pneumatic telescopic arm 15 is connected to a fixed frame 16. It should be noted that multiple sets of cylinders in this device are provided with tension detectors, so as to facilitate data control of the tension force of the second cylinder 14 and the compression force of the first cylinder 3.

[0024] Furthermore, under the action of the second cylinder 14, the fixed frame 16 forms a horizontal pushing structure with the operating table 1 through the second pneumatic telescopic arm 15, thereby driving the plastic profile to stretch to both ends through the second cylinder 14 so as to test its tensile strength.

[0025] A bidirectional screw 17 is inserted into the fixed frame 16, and a second slide rod 18 is provided on one side of the bidirectional screw 17. A second movable block 19 is inserted at both ends of the bidirectional screw 17 and the second slide rod 18, and a limiting plate 20 is provided on the second movable block 19. A plastic profile is placed between the limiting plates 20, and a support plate is provided below the plastic profile on the upper surface of the operating table 1. It should be noted that through holes are opened at both ends of the fixed frame 16 at the bidirectional screw 17 to ensure that the bidirectional screw 17 can rotate normally. This utility model is a plastic profile strength testing device. All components are standard parts or components known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In this device, all the above-mentioned electrical components refer to power components, electrical components, and the matching monitoring computer and power supply connected by wires. The specific connection method should refer to the working principle above, and the electrical connection between each electrical component is completed in sequence. The detailed connection method is a well-known technology in the field.

[0026] Furthermore, the limiting plate 20 forms an extrusion limiting structure with the plastic profile through the bidirectional screw 17, the second slide bar 18, and the second movable block 19. Thus, the rotating bidirectional screw 17 can drive the limiting plate 20 to extrude and limit the plastic profile, thereby enabling it to move in a limited position and facilitating subsequent testing.

[0027] Working Principle: When using the plastic profile strength testing device, the plastic profile to be tested is first placed on the fixed frame 16. The second movable block 19 is driven to move bidirectionally by rotating the bidirectional screw 17. Simultaneously, the second sliding rod 18, inserted into the second movable block 19, limits its movement, ensuring bidirectional limiting sliding. This, in turn, causes the limiting plate 20 to compress and limit the plastic profile, facilitating subsequent limited movement. After the plastic profile is limited, the servo motor 8 is activated. One end of the output shaft of the servo motor 8 drives the screw 9 to rotate via a coupling. The screw 9, in turn, drives another set of screws 9 to rotate synchronously via the first synchronous pulley, the second synchronous pulley, and the synchronous belt. This, in the same principle, drives the first movable block 11 to slide synchronously, thus limiting the movement of the plastic profile. Once in the appropriate position, the first cylinder 3 can be activated to drive the pressure block 5 through the first pneumatic telescopic arm 4 to perform compression strength testing, or the second cylinder 14 can be activated to perform tensile strength testing through the second pneumatic telescopic arm 15. During the strength testing process, sunlight simulator 7 can be used to simulate sunlight irradiation on the plastic profile to perform strength testing on the sunlight-irradiated plastic profile. Thus, multiple sets of testing components ensure the practicality of the device in the plastic profile testing process. During the plastic profile strength testing process, broken plastic fragments can be extracted in time through the dust suction port 6 for subsequent strength testing. Furthermore, during the strength testing process, one set of plastic profiles can be positioned at the other end of the operating table 1 to limit the placement of another set of plastic profiles, ensuring the continuous operation of the device and thus ensuring its working efficiency. This is the usage process of the plastic profile strength testing device.

[0028] Although the present invention 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 invention should be included within the protection scope of the present invention.
