[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts fall within the protection scope of the present utility model.

[0019] Example 1: As shown in Figure 1-2 the figure, the present utility model provides a feeding device for silicone manufacturing, including a feeding ring 1. A feeding hopper 2 is fixedly provided at the lower end of the feeding ring 1. A feeding pipe 3 is fixedly provided at the lower end of the feeding hopper 2. Two feeding pipes 4 are fixedly provided at the upper end of the feeding hopper 2. A support plate 11 is fixedly provided on the upper side of the inner wall of the feeding ring 1. A motor 5 is fixedly provided at the upper end of the support plate 11. The output end of the motor 5 penetrates through the support plate 11 and is fixedly provided with a rotating column 51. A plurality of connecting columns 52 are fixedly provided on the outer surface of the rotating column 51. There are three connecting columns 52 located on the same axis, and the three connecting columns 52 are equally spaced up and down. And the outer ends of the connecting columns 52 located on the same axis are jointly fixedly provided with a scraper 53. There are three scrapers 53, and the three scrapers 53 are annularly distributed. The outer side of the outer surface of the scraper 53 is in movable contact with the inner wall of the feeding hopper 2. The feeding ring 1 and the feeding hopper 2 form a feeding structure. A variety of required materials are put in through the feeding pipes 4. The motor 5 on the support plate 11 is started, so that the rotating column 51 rotates, thereby driving the connecting columns 52 and the scraper 53 to do circular motion. The circular motion structure of the connecting columns 52 constitutes the first stirring structure, which can stir and mix the falling materials, saving the subsequent processing time. And the scraper 53 can scrape the inner wall of the feeding hopper 2 to prevent the materials from sticking to the inner wall and improve the feeding effect.

[0020] A connecting cone 54 is fixedly provided at the lower end of the rotating column 51. A plurality of first stirring columns 55 and second stirring columns 56 are fixedly provided on the outer surface of the connecting cone 54. There are twelve first stirring columns 55 and second stirring columns 56, and the twelve first stirring columns 55 and second stirring columns 56 are annularly distributed. The length ratio of the first stirring column 55 to the second stirring column 56 is three to two. When the rotating column 51 rotates, the connecting cone 54 rotates, so that the first stirring columns 55 and the second stirring columns 56 do circular motion. In this way, the falling materials are stirred and mixed for the second time. The design of the secondary stirring structure makes the mixing of various raw materials more sufficient and the feeding quality higher.

[0021] The two feeding pipes 4 are mirror-image distributed, and a protection groove 41 for using the motor 5 is opened at one end of the feeding pipe 4. An inclined plate 12 is fixedly provided on the lower side of the inner wall of the feeding ring 1, and the outer surface of the rotating column 51 is sleeved and connected with the inclined plate 12. The protection groove 41 provides space for placing the motor 5 and can provide a certain protection for the motor 5. The inclined plate 12 further improves the rotation stability of the rotating column 51.

[0022] Example 2: As shown in Figure 3As shown in the figure, a rotating shaft 31 is provided inside the feed pipe 3, and the upper end of the rotating shaft 31 is fixedly connected to the lower end of the connecting cone 54. A spiral blade 32 is fixedly provided on the outer surface of the rotating shaft 31. When the motor 5 is started, the rotating shaft 31 is driven to rotate through the connecting cone 54. The material is introduced into the feed pipe 3 through the feed hopper 2. The feed pipe 3 serves as the output structure of the material. The rotation of the rotating shaft 31 causes the spiral blade 32 to rotate, forming a dragon-type feeding structure. The rotation of the spiral blade 32 will push the silicone material to be conveyed downward along the feed pipe 3. This conveying method can ensure the continuous and stable conveyance of the material, and the conveying speed can be adjusted according to the rotation speed of the motor 5 to meet the requirements of different production processes.

[0023] Working principle: The feed ring 1 and the feed hopper 2 form a feed structure. A variety of required materials are put in through the feeding pipe 4. The motor 5 on the support plate 11 is started, causing the rotating column 51 to rotate, thereby driving the connecting column 52 and the scraper 53 to perform circular motion. The circular motion of the connecting column 52 constructs the first stirring structure, which can stir and mix the falling materials, saving subsequent processing time. The scraper 53 can scrape the inner wall of the feed hopper 2 to prevent the materials from adhering to the inner wall and improve the feeding effect.

[0024] When the rotating column 51 rotates, the connecting cone 54 rotates, causing the first stirring column 55 and the second stirring column 56 to perform circular motion, so as to perform secondary stirring and mixing on the falling materials. The design of the secondary stirring structure makes the mixing of various raw materials more sufficient and the feeding quality higher.

[0025] The protection groove 41 provides space for placing the motor 5 and can provide a certain degree of protection for the motor 5. The inclined plate 12 further improves the rotation stability of the rotating column 51.

[0026] The material is introduced into the feed pipe 3 through the feed hopper 2. The feed pipe 3 serves as the output structure of the material. The rotation of the rotating shaft 31 causes the spiral blade 32 to rotate, forming a dragon-type feeding structure. The rotation of the spiral blade 32 will push the silicone material to be conveyed downward along the feed pipe 3. This conveying method can ensure the continuous and stable conveyance of the material, and the conveying speed can be adjusted according to the rotation speed of the motor 5 to meet the requirements of different production processes.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
