[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a plastic plate deformation performance testing device, comprising a frame stably placed above the ground, and a hydraulic press is fixedly installed on the upper surface of the frame, and a connecting cylinder is telescopically installed at the output end of the hydraulic press, and a pressure roller is rotatably installed under the connecting cylinder to apply pressure to the plastic plate;

[0016] Preferably, the upper and lower parts of the elastic telescopic rod are connected by a spring to form an elastic telescopic structure, and the lower end of the elastic telescopic rod is integrated with a resistance piece, and the resistance piece is arranged in a spherical structure, and the splint is located on the movement trajectory of the resistance piece, and the position of the resistance piece is lower than the position of the pressure roller.

[0017] By adopting the above technical solution, when the hydraulic press drives the pressure roller and the elastic telescopic rod to move downward, the resistance piece at the lower end of the elastic telescopic rod will contact the clamping plate, thereby pushing the clamping plate to move downward and cooperating with the bottom plate to clamp and fix the end of the plastic plate.

[0018] Preferably, a guide column is symmetrically fixed at the lower end of the clamping plate, and the guide column passes through the bottom plate, and a spring is connected between the lower end of the guide column and the bottom plate, and the elastic force of the spring connected between the guide column and the bottom plate is smaller than the spring force on the elastic telescopic rod.

[0019] By adopting the above technical solution, the resistance member can resist and push the clamping plate to elastically descend during the downward movement, thereby cooperating with the bottom plate to clamp and fix the end of the plastic plate. When the resistance member cannot move downward, the elastic telescopic rod can elastically contract to avoid structural jamming.

[0020] Preferably, the movable frame slides elastically on the slide rail, and the bottom plate rotates elastically at the upper end of the movable frame.

[0021] By adopting the above technical solution, the position and angle of the bottom plate can be automatically adjusted to adapt to the change in the distance between the two ends of the plate body and the inclination of the end of the plate body after the plastic plate is deformed and bent.

[0024] Preferably, the threaded rod and the lifting frame are threadedly connected, and the lifting frame and the movable frame form a lifting structure, and the abutment roller on the lifting frame is adjusted to fit the upper surface of the end of the plastic plate.

[0025] By adopting the above technical solution, when the plastic plate is squeezed, its end will be resisted by the resisting roller, so as to prevent the end of the plastic plate from warping up.

[0027] By adopting the above technical solution, when the middle position of the plastic plate is pressurized and deformed, its two ends will also be resisted by the resistance roller and bend synchronously, thereby realizing multi-position detection. At the same time, the bent ends are attached to the arc plate, which can further improve the clamping stability of the ends of the plastic plate.

[0029] By adopting the above technical solution, when the plastic plate breaks during the deformation process, the connecting tube will be elastically reset, thereby squeezing the airbag, so that the gas in the airbag enters the exhaust duct through the air pipe and blows out downward at high speed, thereby forming a wind curtain to prevent the splash of plastic debris produced by the break.

[0030] Preferably, the collecting assembly includes an elastic membrane fixedly mounted on the movable frame, and the elastic membrane is funnel-shaped, and the lower end of the elastic membrane is fixedly connected to a collecting pipe, and a collecting trough is fixedly mounted on the upper surface of the frame, and the collecting trough and the collecting pipe are fixedly connected.

[0031] By adopting the above technical solution, after the plastic plate breaks, the movable frame can be reset, thereby pulling the elastic membrane, so that the elastic membrane can buffer and gather the falling plastic debris, thereby ensuring that the waste debris falls into the collection trough for collection.

[0032] Compared with the prior art, the beneficial effects of the present invention are: the plastic plate deformation performance testing device can stably clamp the plastic plate to ensure stable pressure, and can use the wind curtain to collect and gather debris after the plastic plate breaks, thereby improving the safety of use.

[0034] 2. A piston plate and an adsorption chamber are provided. As the clamping plate moves downward, it drives the movable plate to move downward synchronously through the guide column, so that the movable plate drives the piston plate to move downward synchronously on the inner side of the adsorption chamber through the pull rod, so that the adsorption chamber can stably adsorb the plastic plate above it;

[0035] 3. A resistance roller and an arc plate are provided. Before the test, the position of the resistance roller is adjusted so that the resistance roller is pressed against the upper surface of the end of the plastic plate. With the pressure of the pressure roller, when the middle position of the plastic plate is deformed and bent, the two ends of the plate body will bend synchronously under the action of the resistance roller to achieve multi-position detection. At the same time, the ends of the plate body are bent and attached to the arc plate, which can further improve the clamping stability of the ends of the plate body and avoid the loosening of the ends of the plate body when pressure is applied;

[0036] 4. An air bag and an exhaust duct are provided.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Example 1: Please refer to Figure 1-Figure 7 As shown, the existing plastic plate deformation performance testing equipment has a single clamping method when in use, which makes the plate end easy to slip during the force application process and affects the testing effect. In order to solve this technical problem, this embodiment discloses the following technical content;

[0050] A plastic plate deformation performance testing device comprises a frame 1 stably placed above the ground, a hydraulic press 2 is fixedly installed on the upper surface of the frame 1, and a connecting cylinder 3 is telescopically installed at the output end of the hydraulic press 2, and a pressure roller 4 is rotatably installed under the connecting cylinder 3 to apply pressure to the plastic plate;

[0051] It also includes: an elastic telescopic rod 5, symmetrically mounted on the outer side of the connecting tube 3; two sets of slide rails 7, fixedly mounted on the upper surface of the frame 1, a movable frame 8 is elastically slidably mounted in the slide rail 7, and a bottom plate 9 is elastically rotatably mounted on the upper end of the movable frame 8, and a clamping plate 10 is provided above the bottom plate 9 for lifting and lowering, and the bottom plate 9 and the clamping plate 10 cooperate to clamp and fix the plastic plate;

[0052] The adsorption assembly is arranged on the bottom plate 9 and is used to realize the adsorption of the flat part of the plastic plate; the fixed plate 16 is fixedly installed on the outer side of the movable frame 8, and a threaded rod 17 is rotatably installed on the fixed plate 16, and a lifting frame 18 is connected to the threaded rod 17, and a resistance roller 19 is rotatably installed on the upper end of the lifting frame 18 to realize the limit of the end of the plastic plate; the arc plate 20 is fixedly installed on the end of the bottom plate 9 and is used to cooperate with the resistance roller 19 to bend the end of the plastic plate;

[0053] The upper and lower parts of the elastic telescopic rod 5 are connected by a spring to form an elastic telescopic structure, and the lower end of the elastic telescopic rod 5 is integrated with a resistance member 6, and the resistance member 6 is arranged in a spherical structure. At the same time, the splint 10 is located on the movement trajectory of the resistance member 6, and the position of the resistance member 6 is lower than the position of the pressure roller 4.

[0054] A guide post 11 is symmetrically fixedly arranged at the lower end of the clamping plate 10, and the guide post 11 penetrates the bottom plate 9, and a spring is connected between the lower end of the guide post 11 and the bottom plate 9, and the elastic force of the spring connected between the guide post 11 and the bottom plate 9 is smaller than the spring elastic force of the elastic telescopic rod 5. The movable frame 8 slides elastically on the slide rail 7, and the bottom plate 9 rotates elastically at the upper end of the movable frame 8.

[0055] The adsorption assembly includes a movable plate 12 fixedly installed at the lower end of the guide column 11, and a pull rod 13 is fixedly connected to the upper surface of the movable plate 12, and a piston plate 14 is fixedly connected to the upper end of the pull rod 13. An adsorption bin 15 is provided on the bottom plate 9, and the piston plate 14 is installed on the inner side of the adsorption bin 15 in an interference seal, and the pull rod 13 passes through the lower end of the adsorption bin 15 to drive the piston plate 14 to be raised and lowered, and at the same time, the upper end of the adsorption bin 15 and the plastic plate are sealed and fitted.

[0056] The threaded rod 17 and the lifting frame 18 are threadedly connected, and the lifting frame 18 and the movable frame 8 form a lifting structure, and the contact roller 19 on the lifting frame 18 is adjusted to fit the upper surface of the end of the plastic plate. The contact roller 19 and the arc plate 20 are respectively located above and below the end of the plastic plate, and the positions of the contact roller 19 and the arc plate 20 correspond to each other, and the end of the plastic plate is gradually bent and fits the arc plate 20 under the contact of the contact roller 19.

[0057] When it is necessary to perform pressure testing on the plastic plate, the plastic plate is inserted horizontally between the bottom plate 9 and the clamping plate 10, and then the threaded rod 17 is rotated so that the threaded rod 17 drives the lifting frame 18 to move downward, ensuring that the resistance roller 19 on the lifting frame 18 is in contact with the upper surface of the plate end, and then the hydraulic press 2 is controlled to drive the pressure roller 4 to move downward. As the pressure roller 4 moves downward, the elastic telescopic rod 5 on the outside of the connecting tube 3 drives the resistance member 6 to move downward synchronously, so that the resistance member 6 contacts the clamping plate 10, so that the clamping plate 10 moves downward elastically, thereby cooperating with the bottom plate 9 to clamp and fix the two ends of the plastic plate. At the same time, the clamping plate 10 drives the movable plate 12 to move downward through the guide column 11, so that the movable plate 12 pulls the piston plate 14 in the adsorption bin 15 through the pull rod 13. The connecting tube 3 and the pressure roller 4 are moved sideways, so that the adsorption bin 15 can synchronously adsorb the plate end on the bottom plate 9. As the connecting tube 3 and the pressure roller 4 continue to move downward, the connecting tube 3 and the hydraulic press 2 will elastically expand and contract, and the elastic telescopic rod 5 will elastically expand and contract. When the connecting tube 3 cannot be expanded or contracted, the pressure roller 4 at its lower end will apply pressure to the middle position of the plastic plate, causing the middle position of the plastic plate to deform and bend. At the same time, the bottom plate 9 will rotate, and the movable frame 8 will elastically slide along the slide rail 7. As the plastic plate bends, its end will bend under the resistance of the resistance roller 19, thereby realizing multi-position detection of the plate body. At the same time, the bent plate end will fit against the arc plate 20, thereby further improving the clamping stability of the plate end.

[0058] Embodiment 2: The technical content disclosed in this embodiment is a further improvement on the above embodiment 1. The existing plastic plate deformation performance testing equipment cannot collect and process the flying debris when the plate is broken. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 3-Figure 4 and Figure 8-Figure 9 As shown, the airbag 21 is arranged on the inner side of the connecting tube 3, and the upper and lower ends of the airbag 21 are respectively fixedly connected to the upper inner wall of the connecting tube 3 and the lower end of the output end of the hydraulic press 2; the exhaust duct 22 is fixedly installed on the upper lower surface of the shell of the hydraulic press 2 to achieve air blowing; the collecting component is arranged between the multiple groups of movable frames 8 to achieve the collection of broken plastic plate debris;

[0059] The exhaust duct 22 and the airbag 21 are connected by an air pipe 23, and a spring is connected between the lower end of the hydraulic press 2 and the connecting tube 3, and an elastic telescopic structure is formed between the connecting tube 3 and the output end of the hydraulic press 2, and the connecting tube 3 stretches and squeezes the airbag 21 when it is telescoped. At the same time, an annular air hole is opened at the lower end of the exhaust duct 22, and the air hole faces the collecting component.

[0060] The collecting assembly includes an elastic membrane 24 fixedly mounted on the movable frame 8, and the elastic membrane 24 is funnel-shaped, and a collecting pipe 26 is fixedly connected to the lower end of the elastic membrane 24. A collecting trough 25 is fixedly mounted on the upper surface of the frame 1, and the collecting trough 25 and the collecting pipe 26 are fixedly connected.

[0061] Through the above technical solution, when pressure is applied, the connecting tube 3 will be elastically displaced with the output end of the hydraulic press 2, thereby stretching the airbag 21. When the plastic plate breaks during the pressure application process, the connecting tube 3 will be elastically reset, thereby instantly squeezing the airbag 21, so that the air sucked into the airbag 21 enters the exhaust duct 22 through the air supply pipe 23, and is ejected at high speed from the air holes of the exhaust duct 22, thereby forming an annular wind curtain, and then blowing the flying debris downward to prevent the debris from splashing. At the same time, the movable frame 8 will be elastically reset and stretch the elastic membrane 24, so that the elastic membrane 24 can buffer the falling debris and guide the debris to the collecting pipe 26, and then fall into the collecting tank 25 through the collecting pipe 26.
