Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for an internal mixer. Background Technology

[0002] In footwear processing, the internal mixer feeding device, as the core functional module of the internal mixer, undertakes the crucial task of accurately and efficiently transporting rubber base materials, plastic additives, and various functional compounding agents (such as vulcanizing agents, accelerators, fillers, etc.) to the mixing chamber, providing a stable and reliable raw material supply guarantee for subsequent mixing processes.

[0003] For example, the utility model disclosed in authorization announcement number CN221733674U discloses a high-efficiency feeding device for a mixer, in which: "When in use, the material is first put into the auxiliary material tank. After the material is refined by the screen, it falls into the feeding hopper. Then, it is weighed by the small material scale and discharged. The materials in other auxiliary material tanks are processed in the same way. They enter the weighing scale through the feed cylinder. After the total weight of the auxiliary materials is qualified, they enter the preparation hopper for later use. The auxiliary materials in the preparation hopper are automatically added to the mixer according to the process steps. Moreover, when the material enters the auxiliary material tank, the motor drives the connecting seat to rotate, thereby causing the two stirring rods at the bottom of the connecting seat to rotate, which disperses the material, making it easier to feed and weigh. The magnetic rod on the stirring rod can remove metal impurities mixed in with the material. When the stirring rod rotates, it will contact the inclined block above the screen and slide on its inclined surface, and will continuously apply downward pressure to the inclined block. Then, in conjunction with the elastic support mechanism, the screen can vibrate. This not only further refines the material, making it easier to weigh and feed, but also prevents it from clogging." However, once the magnetic rod attracts metal debris, the presence of the magnet makes it difficult for the user to clean the metal debris from the surface of the magnetic rod. At the same time, the screen inside the auxiliary material tank affects the material feeding speed, thus affecting the working efficiency of the device. Moreover, during feeding, the material usually gets stuck at the outlet of the auxiliary material tank because the outlet diameter is small and prone to blockage. Utility Model Content

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0013] Please see Figure 1-7 This utility model provides a technical solution: a feeding device for a mixer, including a feeding tank 1, a top cover 2, a motor 3, and a material valve 7. The top cover 2 is installed on the upper end of the feeding tank 1, the motor 3 is installed on the upper end of the top cover 2, and the material valve 7 is installed at the outlet of the feeding tank 1. The feeding tank 1 has a stirring mechanism 4 inside. The upper end of the stirring mechanism 4 is fixedly connected to the output end of the motor 3. The surface of the stirring part of the stirring mechanism 4 is covered with an installation sleeve 5. The stirring part of the stirring mechanism 4 is magnetic. One side of the stirring mechanism 4 is in elastic contact with the inner wall of the feeding tank 1. The discharge port of the feeding tank 1 is rotatably equipped with an anti-blocking mechanism 6. The lower end of the stirring mechanism 4 is inserted into the upper end of the anti-blocking mechanism 6.

[0014] In this implementation scheme, in actual use, after the user pours the material to be processed into the feeding tank 1, they only need to start the motor 3. The motor 3 will drive the stirring mechanism 4 to start rotating at high speed. The stirring mechanism 4 uses its stirring end to perform fine and uniform stirring and dispersing of the material. Since the stirring end of the stirring mechanism 4 is magnetic and has an installation sleeve 5 on its surface, during the stirring process, metal impurities in the material will be firmly adsorbed onto the surface of the installation sleeve 5, effectively avoiding the influence of metal impurities on the subsequent processing. When it is necessary to clean the metal impurities, the user only needs to remove the installation sleeve 5 from the surface of the stirring end of the stirring mechanism 4, so that the installation sleeve 5 is detached from the stirring end of the stirring mechanism 4, thus facilitating the cleaning of the metal impurities.

[0015] Meanwhile, during the rotation of the stirring mechanism 4, its back side will elastically fit against the inner wall of the feeding tank 1. This design allows the stirring mechanism 4 to scrape off the material adhering to the inner wall of the feeding tank 1 while stirring the material, thereby preventing the material from remaining and clumping on the inner wall of the feeding tank 1, and ensuring the cleanliness and efficient operation of the feeding tank 1.

[0016] In addition, an anti-blocking mechanism 6 is installed inside the discharge port of the feeding tank 1. This anti-blocking mechanism 6 is inserted into the lower end of the mixing mechanism 4. When the mixing mechanism 4 rotates, it will synchronously drive the anti-blocking mechanism 6 to rotate. Through its unique cutting action, the anti-blocking mechanism 6 can effectively and promptly clear the material at the outlet of the feeding tank 1, thereby effectively preventing the material from blocking at the outlet of the feeding tank 1 and ensuring the smooth flow of the material.

[0017] At the same time, users only need to activate the material valve 7 to accurately and quickly discharge the processed material from the outlet of the feeding tank 1, providing a stable and reliable material supply for the subsequent mixing process.

[0018] like Figure 3 As shown, the stirring mechanism 4 includes a connecting plate 41, a folding plate 42, a scraper 43, an insert block 44, a magnetic rod 45, a positioning groove 46, and a threaded groove 47. The output end of the motor 3 is fixedly connected to the connecting plate 41. One end of the connecting plate 41 is fixedly connected to the folding plate 42. A plurality of magnetic rods 45 are fixedly connected to one side of the folding plate 42. The other side of the folding plate 42 is fixedly connected to the scraper 43. The scraper 43 contacts the inner wall of the feeding tank 1. A positioning groove 46 and a threaded groove 47 are provided on one side of the folding plate 42. The lower end of the folding plate 42 is fixedly connected to the insert block 44.

[0019] In this embodiment, the user starts the motor 3, which drives the folding plate 42 to rotate through the connecting plate 41, thereby driving the scraper 43 and the magnetic rod 45 to rotate. The scraper 43 contacts the inner wall of the feeding tank 1, thereby scraping off the material attached to the inner wall of the feeding tank 1, while the magnetic rod 45 can adsorb metal impurities onto the surface of the mounting sleeve 5.

[0020] like Figure 4 As shown, the mounting sleeve 5 includes a sliding sleeve 51, a positioning block 52, and a bolt 53. The sliding sleeve 51 is fitted on the surface of the magnetic rod 45. One end of the sliding sleeve 51 is fixedly connected to the positioning block 52. The positioning block 52 is adapted to the positioning groove 46. The sliding sleeve 51 is installed on one side of the folding plate 42 by the bolt 53.

[0021] In this embodiment, when the installation sleeve 5 needs to be installed, the user puts the sliding sleeve 51 on the surface of the magnetic rod 45, so that the positioning block 52 is inserted into the interior of the positioning groove 46. At this time, the sliding sleeve 51 can be installed on the surface of the magnetic rod 45 using the bolt 53.

[0022] like Figure 6 As shown, the anti-blocking mechanism 6 includes a sliding ring 61, a locking block 62, a connecting block 63, and discharge plates 64. The sliding ring 61 is rotatably arranged inside the discharge port of the feeding tank 1. The inner end of the sliding ring 61 is fixedly connected to the locking block 62, which engages with the insert block 44. The lower end of the locking block 62 is fixedly connected to the connecting block 63, and multiple discharge plates 64 are fixedly connected to the surface of the connecting block 63.

[0023] In this embodiment, since the folding plate 42 is inserted into the slot of the locking block 62 through the insert block 44, when the folding plate 42 rotates, it will drive the locking block 62 and the sliding ring 61 to rotate inside the discharge port of the feeding tank 1. This will drive the multiple discharge plates 64 to rotate through the connecting block 63, thereby discharging the material and preventing the material from blocking the discharge port of the feeding tank 1.

[0024] like Figure 6 As shown, multiple discharge plates 64 are inclinedly arranged on the surface of the connecting block 63.

[0025] In this embodiment, since the discharge plate 64 is inclined, it has the function of discharging materials when the discharge plate 64 rotates.

[0026] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
