[0003] However, the existing plastic parts feeding mechanism is not convenient for intermittent feeding of plastic parts according to a fixed time difference during use. Continuous feeding may lead to accumulation of materials, and untimely feeding may lead to material shortage. Utility Model Content

[0004] The purpose of the utility model is to provide a plastic parts feeding mechanism. By setting up an intermittent feeding mechanism, the problem that the existing plastic parts feeding mechanism is not convenient for conveying plastic parts intermittently according to a fixed time difference during use is solved, and continuous feeding may cause accumulation of materials, while untimely feeding may lead to material shortage.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a plastic parts feeding mechanism, comprising a workbench, on which an intermittent conveying mechanism and a scraping mechanism are arranged;

[0007] A silo is provided on the workbench, a support frame is fixedly connected to the outer wall of the silo, the bottom of the support frame is fixedly connected to the workbench, the top of the workbench is fixedly connected to a rectangular ring, the intermittent conveying mechanism includes an intermittent conveying component 1 and an intermittent conveying component 2, the intermittent conveying component 1 includes a circular ring arranged above the workbench, a plurality of fixed rods are fixedly connected to the outer wall of the support frame, and the sides of the plurality of fixed rods close to each other are fixedly connected to the circular ring.

[0008] Furthermore, a rotation groove is provided on the inner wall of the circular ring, and a disc is rotatably connected to the inner wall of the rotation groove.

[0009] Furthermore, the second intermittent conveying component includes two feeding pipes connected and arranged at the bottom of the disc, and the bottoms of the two feeding pipes are hingedly provided with cover plates.

[0010] Furthermore, the bottoms of the two cover plates are fixedly connected with connecting pieces, the bottom of the silo is fixedly connected with a special-shaped adapter ring, the bottom of the special-shaped adapter ring passes through the disc and extends to the outside, and the two connecting pieces are adapted to the special-shaped adapter ring.

[0011] Furthermore, the scraping mechanism includes a rotating shaft 1 that rotates and passes through the workbench. The bottom of the workbench is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to the rotating shaft 1 through a coupling.

[0012] Furthermore, a half gear is fixedly connected to the top extension of the rotating shaft 1, and the top of the workbench is fixedly connected to the rotating shaft 2. The top of the rotating shaft 2 passes through the disc and is fixedly connected to the disc, and the top of the rotating shaft 2 rotates and extends into the silo.

[0013] Furthermore, a gear is fixedly connected to the outer wall of the second rotating shaft, and the gear is engaged with the half gear. Two scrapers are fixedly connected to the top extension of the motor, and the bottoms of the two scrapers are in contact with the silo.

[0014] Furthermore, a discharge port is provided at the bottom of the silo, and the tops of the two feeding pipes are connected with connecting pipes, and the top of the connecting pipe located at the rear side is connected to the discharge port.

[0015] The utility model has the following beneficial effects:

[0016] 1. By setting up an intermittent transmission mechanism, when the rotating shaft 2 rotates intermittently, it will drive the disc to rotate. When the disc rotates, the two feeding pipes will also rotate. Since the teeth of the half gear are set to half of the conventional gear, the half gear rotates one circle, and the feeding pipe at the rear side just rotates to the front side, and the feeding pipe at the front side rotates to the rear side and is connected with the connecting pipe. Since the front side of the special-shaped adapter ring is provided with a notch, when the feeding pipe rotates to the front side, the connecting piece will lose its restriction on the feeding pipe under the action of this notch. Due to the gravity of the plastic part, the cover plate The cover plate will be opened to discharge the material. When the half gear rotates again, the cover plate will be reset under the simultaneous action of the connecting piece and the notch on the special-shaped adapter ring, thus completing the intermittent feeding of the plastic parts reciprocatingly. The intermittent feeding can effectively avoid the accumulation or shortage of plastic parts on the workbench. Moreover, only when the feeding tube rotates to the front side, the connecting piece loses its restriction on the feeding tube under the action of the notch, and the plastic parts rely on gravity to discharge, avoiding the accidental leakage of materials when unloading is not required.

[0017] 2. By setting up a scraper mechanism, when feeding is needed, the motor can be started, and the motor drives the half gear to rotate through the rotating shaft 1. When the half gear rotates, it drives the gear to rotate intermittently, and when the gear rotates, it drives the scraper on the rotating shaft 2 to rotate intermittently, thereby scraping the plastic parts in the silo through the discharge port and the connecting pipe into the feeding pipe at the rear side. Each time the scraper rotates, only a certain amount of plastic parts is transported, so that the plastic parts can enter the feeding pipe through the discharge port and the connecting pipe in a more orderly manner, thereby effectively preventing blockage during the feeding process.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the rotating shaft 2 304 rotates intermittently, it drives the disc 214 to rotate. When the disc 214 rotates, the two feeding pipes 221 will also rotate accordingly. Since the teeth of the half gear 303 are set to half of those of a conventional gear, the half gear When the gear 303 rotates one circle, the feeding tube 221 at the rear side just rotates to the front side, and the feeding tube 221 at the front side rotates to the rear side and is connected with the connecting tube 308. Since a notch is provided on the front side of the special-shaped adapter ring 224, when the feeding tube 221 rotates to the front side, the connecting piece 223 loses its restriction on the feeding tube 221 under the action of the notch. Due to the gravity of the plastic parts, the cover plate 222 will be opened, thereby unloading the material. When the half gear 303 rotates again, the cover plate 222 will be reset under the simultaneous action of the connecting piece 223 and the notch on the special-shaped adapter ring 224, thereby completing the intermittent feeding of the plastic parts in a reciprocating manner. Intermittent feeding can effectively avoid the accumulation or shortage of plastic parts on the workbench, and only when the feeding tube rotates to the front side, the connecting piece 223 loses its restriction on the feeding tube under the action of the notch, and the plastic parts rely on gravity to unload, thereby avoiding the accidental leakage of materials when unloading is not required.
