Description

Technical Field

[0001] The utility model relates to the technical field of plastic product manufacturing, and particularly relates to a self-priming feeding machine for plastic product manufacturing. Background Technique

[0002] Plastic is a widely used material, and its manufacturing process is complex and diverse. The manufacturing process of plastic can be divided into several key steps: raw material extraction, polymerization reaction, molding processing, and post-treatment. During the molding process, there is injection molding, where plastic particles are melted at high temperature and injected into a mold for molding. During the lifting process of plastic particles, self-priming feeding machines are widely used. After retrieval, the patent with the publication number CN219946893U discloses a self-priming feeding mechanism for plastic production. When in use, the suction fan is started, and the suction fan sucks plastic particles from the feed pipe and introduces them into the upper cylinder through the discharge pipe. Then the motor is started, and with the cooperation of the bevel gear transmission structure one and the bevel gear transmission structure two, the cam one and the cam two rotate. When the convex end of the cam one abuts against the abutting plate one, the lifting seat drives the striking wheel to move downward. When the convex end of the cam two abuts against the abutting plate two, the lifting seat drives the striking wheel to move upward. Therefore, the striking wheel intermittently strikes the filter screen, causing the filter screen to perform a jittering screening on the plastic particles. However, it is not convenient to screen plastic particles by specification, and thus the burden on the filter screen is relatively heavy. The screened plastic particles still need to be further exported and subjected to subsequent processing. Therefore, a self-priming feeding machine for plastic product manufacturing is designed, which is convenient for filtering out larger plastic particles in the plastic particles according to specifications at the initial stage of negative pressure adsorption, performing crushing treatment on them, and putting them into the subsequent plastic particle feeding process.

[0024] Embodiment:

[0025] Please refer to Figure 1-6 Figure 1-6 , a self-priming feeding machine for manufacturing plastic products, which includes a negative pressure fan 1. The input end of the negative pressure fan 1 is connected to a negative pressure suction pipe 2. The bottom of the negative pressure suction pipe 2 is sequentially connected to a plurality of connecting pipes 4. Each connecting pipe 4 is connected to a crushing tank 6 through a downwardly inclined material guiding pipe 5. And the plurality of said material guiding pipes 5 are arranged staggeredly. A filtering mechanism with a plurality of vertically arranged filter holes is provided above the position where the connecting pipe 4 communicates with the material guiding pipe 5. The apertures of the filter holes in the plurality of filtering mechanisms decrease sequentially from bottom to top. The connecting pipe 4 also includes a self-driven peeling mechanism adapted to the filtering mechanism. A crushing mechanism is provided on the crushing tank 6. The bottoms of the plurality of connecting pipes 4 are connected to a suction pipe 16 whose bottom is lower than the crushing tank 6.

[0026] Specifically, the filtering mechanism includes a filter plate 7 fixedly installed in the connecting pipe 4. A plurality of filter holes are vertically arranged on the filter plate 7. The self-driven peeling mechanism includes a self-driven peeling frame rotatably connected to the bottom of the filter plate 7 and flush with the bottom end surface of the filter plate 7. The bottom of the self-driven peeling frame is higher than the bottom of the connection between the connecting pipe 4 and the material guiding pipe 5. When the plastic particles are sucked from the bottom upwards, they are filtered by the filter plate 7. At the same time, due to the effect of negative pressure, the self-driven peeling frame is driven to rotate. The plastic particles filtered down are thrown into the material guiding pipe 5 under the rotation of the self-driven peeling frame.

[0027] Specifically, the self-driven peeling frame includes a rotating shaft 8 vertically penetrating through the filter plate 7. Both sides of the rotating shaft 8 are provided with support frames 10 fixedly connected to the connecting pipe 4. The two ends of the rotating shaft 8 are respectively rotatably connected to the support frames 10 on both sides. A plurality of air-induced scraping strips 9 whose tops are in contact with the bottom end surface of the filter plate 7 are circumferentially and fixedly installed on the rotating shaft 8. The bottom ends of the air-induced scraping strips 9 are lower than the bottom of the connection between the connecting pipe 4 and the material guiding pipe 5. When the negative pressure is started, the plurality of air-induced scraping strips 9 are driven to rotate, so as to scrape the bottom of the filter plate 7 and make it thrown into the material guiding pipe 5. The rotating shaft 8 can be supported by the two support frames 10 to increase the structural stability.

[0028] Specifically, the crushing mechanism includes a crushing shaft 11 rotatably connected to the crushing tank 6 through a crushing motor 13. A plurality of crushing blades 12 are fixedly installed on the crushing shaft 11. Starting the crushing motor 13 facilitates driving the crushing shaft 11 to rotate, thereby driving the plurality of crushing blades 12 to rotate, so as to break larger plastic particles.

[0029] Specifically, a discharge valve 14 is installed at the bottom of the crushing tank 6. Through the setting of the discharge valve 14, it is convenient to control the discharge time and make the plastic particles broken more thoroughly.

[0030] Specifically, the negative pressure suction pipe 2 and the connecting pipe 4, between adjacent connecting pipes 4, between the material suction pipe 16 and the lowermost connecting pipe 4, and between the material guiding pipe 5 and the crushing tank 6 are all connected by flanges. The flange connection facilitates disassembly, and thus facilitates replacement, maintenance, and removal of the crushing tank 6, and only larger plastic particles can be separated. Further, a feed pipe 15 in the same direction as the material guiding pipe 5 is provided on the crushing tank 6, and the feed pipe 15 is flange-connected to the material guiding pipe 5.

[0031] Specifically, a feeding pipe 3 is fixedly installed at the output end of the negative pressure fan 1. Through the arrangement of the feeding pipe 3, it is convenient to divert the lifted plastic particles to the required equipment.
