Abstract
Description
Technical Field
[0001] This utility model discloses a waste chip collection device for grinding injection mold parts, which relates to the field of waste recycling equipment. Background Technology
[0002] Waste recycling generated during the grinding of injection mold parts is an important step in improving resource utilization and reducing environmental impact. Effective waste recycling reduces the burden on landfills and lowers environmental pollution. Metal grinding waste can be used in casting or forging processes to produce new parts. Effective waste recycling also promotes the recycling of materials and reduces production costs.
[0003] Waste generated during the grinding of injection mold parts includes fine grinding particles, usually metal or plastic, as well as scraps and large pieces of material left over from the cutting and grinding process. Typically, the processing waste is sent to a waste collection device all at once. When workers remove and recycle it, the fine powder and waste chips may be stirred up when removing the large pieces of material, which may cause injury to the operators if inhaled. A large amount of dust adheres to the large pieces of material, and separation takes time. Therefore, there is a need to provide a waste collection device for grinding injection mold parts to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a waste chip collection device for grinding injection mold parts, so as to achieve the effect of classifying and recycling waste chips of different particle sizes after grinding injection mold parts.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste chip collection device for grinding injection mold parts, comprising a frame, a working part for waste recycling mounted on the frame, a discharge port mounted on the working part, and a recycling box mounted below the working part; the recycling box includes a particle collection box and a powder collection box, which are fixedly connected, a particle outlet on the outside of the particle collection box for classifying large particle materials, and a powder outlet on the outside of the powder collection box for recycling powder waste chips; the working part includes a housing, a rotating shaft mounted at the central shaft inside the housing, several sets of guide fan blades mounted on the rotating shaft, a pusher impeller mounted on the rotating shaft, and a discharge filter screen mounted below the guide fan blades.
[0006] Preferably, the feed filter screen is installed below the guide fan blades, with the top of the guide fan blades contacting the upper surface of the feed filter screen. The feed filter screen is installed above the powder collection box, and a particle collection box is installed below the pusher impeller.
[0007] Preferably, the feed filter screen is provided with a large number of fine through holes.
[0008] Preferably, the pusher impeller is equipped with several sets of fan impellers, and a scraper is rotatably connected to the top of the fan impeller. A torsion spring is provided at the connection between the scraper and the fan impeller, and the scraper contacts the upper surface of the feed filter screen.
[0009] Preferably, the rotating shaft is driven by a motor.
[0010] Preferably, the guide blades are distributed in an inclined spiral pattern on the rotating shaft.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By driving the rotating shaft to rotate by a motor, several sets of inclined spiral-shaped guide fan blades and pusher impellers rotate. The guide fan blades can convey the waste chips. The top of the guide fan blades contacts the upper surface of the feed filter screen, which can guide the large waste chips on the feed filter screen to the pusher impeller. Then, the rotation of the pusher impeller pushes the large particles into the particle collection box, achieving the effect of classified recycling. The top of the guide fan blades contacts the upper surface of the feed filter screen, and while rotating to convey, it can also scrape off the sticky waste chips on the feed filter screen, realizing the scraping function inside the machine. Therefore, a torsion spring is set between the scraper and the fan impeller, so that the scraper can move adaptively, thereby solving the problem of material jamming causing structural damage.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Specific implementation examples:
[0018] like Figure 1 As shown, a waste chip collection device for grinding injection mold parts includes a frame 1, a working part 2 for waste recycling is installed on the frame 1, a discharge port 3 is installed on the working part 2, and a recycling box 4 is installed below the working part 2.
[0019] When the waste collection device is in operation, the waste enters the working section 2 through the discharge port 3. The working section 2 carries out the waste through a sorting process. The sorted waste in the working section 2 finally enters the recycling bin 4.
[0020] like Figures 1-2 As shown, the recycling bin 4 includes a particle collection bin 44 and a powder collection bin 43. The particle collection bin 44 and the powder collection bin 43 are fixedly connected. The particle collection bin 44 has a particle outlet 42 on its outside for classifying large particle materials. The powder collection bin 43 has a powder outlet 41 on its outside for recycling powder waste.
[0021] After being sorted by the working section 2, small injection mold parts waste will enter the powder collection box 43 and be discharged from the powder outlet 41. Similarly, large parts or large particles of injection mold parts waste will enter the particle collection box 44 and be discharged from the particle outlet 42.
[0022] like Figure 2 As shown, the working part 2 includes a housing 21, and a rotating shaft 22 is installed at the central axis inside the housing 21. The rotating shaft 22 is driven by a motor. Several sets of guide fan blades 23 are installed on the rotating shaft 22. The guide fan blades 23 are distributed in an inclined spiral pattern on the rotating shaft 22. A pusher impeller 24 is installed on the rotating shaft 22. A discharge filter screen 25 is installed below the guide fan blades 23.
[0023] The feeding filter 25 is installed below the guide fan blade 23, the top of the guide fan blade 23 is in contact with the upper surface of the feeding filter 25, the feeding filter 25 is installed above the powder collection box 43, and a particle collection box 44 is installed below the pusher impeller 24.
[0024] The guide fan blades 23, the feeding filter screen 25, and the powder collection box 43 are positioned relative to each other. Several sets of inclined spiral-shaped guide fan blades 23 can convey the waste chips. The top of the guide fan blades 23 contacts the upper surface of the feeding filter screen 25, which can guide the large waste chips on the feeding filter screen 25 to the pusher impeller 24. Then, the rotation of the pusher impeller 24 pushes the large particles into the particle collection box 44.
[0025] The feed filter screen 25 is provided with a large number of fine through holes;
[0026] The numerous tiny holes in the feed filter 25 allow powdery waste to enter the powder collection box 43. The powdery waste remaining in the feed filter 25 will be scraped off as the top of the guide fan blade 23 contacts the upper surface of the feed filter 25 and rotates to feed.
[0027] The pusher impeller 24 is equipped with several sets of fan impellers 241. The top of the fan impeller 241 is rotatably connected to a scraper 242. A torsion spring 244 is provided at the connection between the scraper 242 and the fan impeller 241. The scraper 242 is in contact with the upper surface of the discharge filter screen 25.
[0028] When the pusher impeller 24 scrapes off large waste materials, the scraper 242 may get stuck in the gap when it contacts the upper surface of the discharge filter screen 25, causing structural damage. Therefore, a torsion spring 244 is provided between the scraper 242 and the fan impeller 241 so that the scraper 242 can move adaptively, thereby solving the problem of structural damage caused by material jamming.
[0029] In summary, by driving the rotating shaft 22 to rotate, several sets of inclined spiral-shaped guide blades 23 and pusher impellers 24 rotate. The guide blades 23 can convey waste chips, and the top of the guide blades 23 contacts the upper surface of the discharge filter screen 25, which can guide large waste chips on the discharge filter screen 25 to the pusher impeller 24. Then, the rotation of the pusher impeller 24 pushes the large particles into the particle collection box 44, achieving the effect of classified recycling. The top of the guide blades 23 contacts the upper surface of the discharge filter screen 25, and while rotating to convey, it can also scrape off the sticky waste chips on the discharge filter screen 25, realizing the scraping function inside the casing 21. Therefore, a torsion spring 244 is set between the scraper 242 and the impeller 241, so that the scraper 242 can move adaptively, thereby solving the problem of material jamming causing structural damage.
