[0002] Plastic parts are widely used in our lives, from small components in mobile phones to computers, home appliances, automobiles, and medical devices. Every day, a large number of plastic hardware parts are put into production. Relying solely on manual inspection to check the appearance, dimensions, and quality of these products makes it difficult to guarantee the efficiency and accuracy of the inspection process. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a detection and discharge device for injection molded parts production.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a detection and discharge device for injection molded parts production, comprising a conveyor belt, a protective frame, a first collection basket, and a second collection basket. Protective frames are provided on both sides of the conveyor belt. The detection and discharge device for injection molded parts production further includes a screen frame, a filter screen, a funnel, a cylinder, a hinge seat, a support frame, support legs, and sliders. The filter screen is connected between the screen frame and the funnel. Several sliders are connected to both ends of the screen frame, and the sliders are slidably connected to both sides of the support frame. Both ends of the cylinder are hinged to the screen frame and the support frame via a hinge seat, and the hinge seat is fixedly connected to the screen frame and the support frame. Several support legs are connected to the edges of the support frame. The screen frame has an inlet and an outlet at both ends, with the inlet connecting to the outlet of the conveyor belt. The first collection basket and the second collection basket are respectively located below the funnel and the outlet.

[0005] Compared with existing technologies, the advantages of this invention are as follows: A conveyor belt transports the workpiece through the feed inlet to the screen frame. A slider is installed between the screen frame and the support frame, allowing the screen frame to slide on the support frame. A cylinder and a hinge seat are installed between the screen frame and the support frame. During the cylinder's extension and retraction, it drives the screen frame to reciprocate on the support frame. Workpieces with acceptable dimensions pass through a filter screen and funnel into the first collection basket, while oversized workpieces fall into the second collection basket through the discharge outlet. This completes the inspection, screening, and discharge process for oversized injection molded parts. Attached Figure Description

[0011] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0012] See appendix Figure 1-4 As shown, a material discharge and inspection device for injection molded parts production in this embodiment includes a conveyor belt 1, a guard frame 2, a first collection basket 7, a second collection basket 8, a screen frame 4, a filter screen 5, a funnel 6, a cylinder 10, a hinge seat 11, a support frame 12, support legs 13, and sliders 14. Guard frames 2 are provided on both sides of the conveyor belt 1. The filter screen 5 is connected between the screen frame 4 and the funnel 6. Several sliders 14 are connected to both ends of the screen frame 4, and the sliders 14 are slidably connected to both sides of the support frame 12. Both ends of the cylinder 10 are hinged to the screen frame 4 and the support frame 12 via a hinge seat 11, and the hinge seat 11 is fixedly connected to the screen frame 4 and the support frame 12. Several support legs 13 are connected to the edges of the support frame 12. The screen frame 4 has an inlet 15 and an outlet 16 at both ends, with the inlet 15 connecting to the outlet of the conveyor belt 1. The first collection basket 7 and the second collection basket 8 are respectively located below the funnel 6 and the outlet 16.

[0013] Conveyor belt 1 transports workpieces through inlet 15 to screen frame 4. A slider 14 is installed between screen frame 4 and support frame 12, allowing screen frame 4 to slide on support frame 12. A cylinder 10 and hinge seat 11 are installed between screen frame 4 and support frame 12. During the extension and retraction of cylinder 10, screen frame 4 is driven to reciprocate on support frame 12. Workpieces of acceptable size pass through filter screen 5 and funnel 6 into first collection basket 7, while oversized workpieces fall into second collection basket 8 through outlet 16. This completes the inspection, screening, and discharge operation for oversized injection molded parts.

[0014] To facilitate the return of the screen frame 4 to its initial position, this invention further comprises the following configuration: the other side of the screen frame 4 is connected to the end of the support frame 12 via several springs 9, with the springs 9 positioned opposite to the cylinder 10. The springs 9 push the screen frame 4 back to its initial position. Then, the cylinder 10 again pushes the screen frame 4 and the slider 14 to move on the support frame 12. After repeating this process multiple times, the workpieces in the screen frame 4 are inspected, screened, and discharged into the first collection basket 7 and the second collection basket 8.

[0015] To facilitate assembly, this invention is further configured such that the hinge seat 11 is fixedly connected to the screen frame 4 and the support frame 12 via a bolt assembly 17. This invention uses a hinged connection to connect the cylinder 10 to the screen frame 4 and the support frame 12, resulting in more flexible movement.

[0016] To facilitate the connection between the protective frame 2 and the screen frame 4 and prevent the workpiece from falling through the gap between them, this invention is further configured such that a connecting groove 3 is provided between the protective frame 2 and the screen frame 4. The conveyor belt 1 transports the workpiece through the connecting groove 3 to the screen frame 4.

[0017] To facilitate more flexible connection between the protective frame 2 and the screen frame 4, this invention further comprises: the connecting groove 3 including a cloth piece 18 and several dovetail clips 19. The cloth piece 18 is folded into a groove shape, and the two ends of the cloth piece 18 are connected to the protective frame 2 and the feed inlet 15 through the dovetail clips 19. The cloth piece 18 is soft and easy to bend, forming a groove shape. Its two ends are connected to the protective frame 2 and the feed inlet 15 through the dovetail clips 19 respectively. This design is simple to operate, provides a close connection, and prevents workpieces from falling through gaps.

[0018] To facilitate the discharge of larger workpieces, this invention is further configured such that the screen frame 4 is inclined, and the height of the inlet 15 is higher than the height of the outlet 16. The workpiece, relying on its own gravity, rolls on the slope formed by the filter screen 5, passes through the outlet 16, and falls into the second collection basket 8.

[0019] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
