[0001] This utility model relates to the field of receiving mechanisms, and in particular to a receiving and distributing mechanism for an injection molded parts appearance screening machine. Background Technology

[0002] With the improvement of automation level in manufacturing, injection molded parts full appearance screening machine has become an indispensable piece of equipment in the production line. It is used to automatically detect and sort surface defects of injection molded parts (such as scratches, burrs, black spots, shrinkage, etc.). After screening, qualified and unqualified products need to be classified, collected and transported by receiving and sorting mechanism to ensure the smooth operation of subsequent processes.

[0003] Most existing material receiving and dispensing mechanisms, such as simple linear vibrating chutes, gravity chutes, or pneumatic conveying pipes, rely on the free fall, hard impact, or high-speed airflow of materials for their operation. During these processes, frequent and intense friction and impact occur between injection molded parts and between the injection molded parts and the equipment walls. For injection molded parts requiring high gloss and prone to scratches, this method can easily lead to scratches, dents, stress whitening, or even direct cracking, causing avoidable secondary damage and significantly increasing the defect rate.

[0015] Beneficial effects This utility model provides a material receiving and distributing mechanism for an injection molded part appearance screening machine. Compared with the prior art, it has the following advantages: 1. In this utility model, through the arc-shaped material guiding mechanism, when the injection molded part is put into the receiving and distributing mechanism from the inlet, the rotating drum, driven by the motor, rotates continuously and uniformly through the rotating seat. The injection molded part inside the drum is immediately subjected to centrifugal force and drum wall friction, and is driven to rotate along the drum wall. When the rotating drum rotates with the injection molded part, the blades of the spiral conveyor frame will continuously scoop up the injection molded part from the bottom. Under the combined action of rotational centrifugal force and spiral blade thrust, the injection molded part will be smoothly conveyed from the bottom of the rotating drum to the arc-shaped receiving rail along the track of the spiral conveyor frame. As subsequent injection molded parts are continuously conveyed, the injection molded parts accumulated on the arc-shaped receiving guide rail are also distributed to the appearance screening machine along its guide rail path. Through the combination of rotation, spiral lifting and arc sliding, hard collisions are avoided during the receiving process of the injection molded parts, reducing the risk of damage to the surface of the injection molded parts. It is especially suitable for high-precision, easily scratched or fragile injection molded parts. 2. In this utility model, by setting a vibration pressure bar, when the electric push rod drives the linear moving arm to reciprocate, the connecting arm will swing accordingly. Since the connecting arm is rotatably connected to the vibration pressure bar, this swing will be transformed into the periodic pressing and releasing action of the vibration pressure bar on the vibratory plate. During the vibration of the vibratory plate, the injection molded parts accumulated at the bottom of the rotating cylinder will bounce to the surface of the spiral conveyor frame, thereby reducing the accumulation of injection molded parts in the rotating cylinder.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

The arc-shaped material guiding mechanism 4 is disposed inside the receiving outer frame 1 and includes a rotating cylinder 401, a spiral conveyor frame 402, an arc-shaped material receiving rail 403, a connecting bracket 404, a material receiving guide rod 405, and a side baffle 406. The spiral conveyor frame 402 is fixedly connected to the inner side of the rotating cylinder 401, and the arc-shaped material receiving rail 403 is provided on the outer side of the rotating cylinder 401. One end of the spiral conveyor frame 402 is connected to the arc-shaped material receiving rail 403. 03 A receiving guide rod 405 is provided at the end away from the spiral conveyor frame 402. A side baffle 406 is fixedly connected to the inner side of the upper end of the receiving guide rod 405. The lower end of the receiving guide rod 405 is fixedly connected to the upper surface of the connecting bracket 404. The lower end of the connecting bracket 404 is fixedly connected to the receiving outer frame 1. It should be noted that the discharge end of the receiving guide rod 405 is connected to the inlet area of ​​the injection molding part appearance screening machine. The lower end of the rotating cylinder 401 is fixedly connected to the upper surface of the rotating seat 6. A motor 5 is provided below the rotating seat 6. The output end of the motor 5 is connected to the rotating seat 6 for transmission.

[0020] During operation, when the injection molded part is fed into the receiving and distributing mechanism from the inlet 2, the rotating cylinder 401, driven by the motor 5, rotates continuously and at a constant speed through the rotating seat 6. The injection molded part inside the cylinder is immediately subjected to centrifugal force and cylinder wall friction, and is driven to rotate along the cylinder wall. As the rotating cylinder 401 rotates with the injection molded part, the blades of the spiral conveyor frame 402 continuously scoop up the injection molded part from the bottom. Under the combined action of rotational centrifugal force and spiral blade thrust, the injection molded part is smoothly conveyed from the bottom of the rotating cylinder 401 to the arc-shaped receiving rail 403 along the track of the spiral conveyor frame 402. As subsequent injection molded parts are continuously conveyed, the injection molded parts accumulated on the arc-shaped receiving rail are also distributed to the appearance screening machine along its guide path. Through the combination of rotation, spiral lifting and arc sliding, hard collisions are avoided during the receiving process of the injection molded parts, reducing the risk of damage to the surface of the injection molded parts. It is especially suitable for high-precision, easily scratched or fragile injection molded parts.

[0021] Example 2: Based on Embodiment 1, a rotating cylinder 401 is disposed inside a vibratory feeder 3. A vibratory pressure rod 13 is disposed on the upper surface of the vibratory feeder 3 at the location of the rotating cylinder 401. The upper end of the vibratory pressure rod 13 is rotatably connected to the inner side of a connector 14. A connecting arm 12 is fixedly connected to the end of the connector 14 away from the vibratory pressure rod 13. The lower end of the connecting arm 12 is rotatably connected to the upper surface of the vibratory feeder 3. A linear moving arm 11 is fixedly connected to the lower end of the connecting arm 12. An electric push rod 10 is disposed below the linear moving arm 11. The free end of the electric push rod 10 is connected to the linear moving arm 11 via a transmission connection. The fixed end of the electric push rod 10 is fixedly connected to a receiving frame 1. An inlet 2 is disposed on the upper surface of the receiving frame 1 for feeding. An inlet funnel 7 is fixedly connected inside the inlet 2. An antistatic rubber sheet 8 is provided on the inner slope surface of the inlet funnel 7 to prevent the injection molded parts from falling and getting damaged. A vertical baffle 9 is fixedly connected to the lower end of the inlet funnel 7. When the electric push rod 10 drives the linear moving arm 11 to reciprocate, the connecting arm 12 will swing accordingly. Since the connecting arm 12 is rotatably connected to the vibrating pressure rod 13, this swing will be converted into the periodic pressing and releasing action of the vibrating pressure rod 13 on the vibrating plate 3. During the vibration of the vibrating plate 3, the injection molded parts accumulated at the bottom of the rotating cylinder 401 will bounce to the surface of the spiral conveyor frame 402, thereby reducing the accumulation of injection molded parts in the rotating cylinder 401.

[0022] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
