Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically a screw feeding device for uniform feeding. Background Technology

[0002] Screw feeding technology is a material supply method commonly used in extrusion molding processes, especially in the extrusion processing of polymer materials such as rubber and plastics, for example, in the production of automotive flocked sealing strips.

[0003] An investigation revealed that a Chinese utility model patent discloses a screw feeding device for uniform feeding (publication number: CN211997471U), comprising a crusher, a feeding box, a screw, and a feeding pipe. The feeding pipe is disposed between the crusher and the feeding box. A feeding hopper is provided at the top of the feeding box, and a discharge hopper communicating with the crusher cavity is provided on the feeding pipe. The screw is horizontally placed sequentially at the bottom of the feeding box and in the feeding pipe. One end of the screw located in the feeding box penetrates the side wall of the feeding box and is connected to a motor. The other end of the screw away from the feeding box is movably connected to the end of the feeding pipe. The screw is provided with equally spaced spiral blades, and the surface of the spiral blades is provided with several rakes perpendicular to them.

[0004] In the aforementioned patent, the loose material is stirred by the rake nails set on the surface of the spiral blades, so that it can be dispersed and evenly entered into the crusher and fully crushed, resulting in a good crushing effect. However, even though this method improves the crushing efficiency to a certain extent, it still cannot completely ensure the uniformity of each feeding. When the feeding is uneven, the material may rush into the space between the spiral blades in a short period of time, quickly and completely filling the space between the blades, which may lead to local accumulation or compression of the material into lumps.

[0005] Therefore, this utility model provides a screw feeding device with uniform feeding to solve the above problems. Utility Model Content

[0027] 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.

[0028] This utility model provides a screw feeding device for uniform feeding, such as... Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the screw feeding device for uniform feeding includes a workbench 1, a support plate 2 fixedly installed on the workbench 1, a feeding cylinder 3 fixedly installed on the support plate 2, a feeding hopper 4 fixedly installed on the feeding cylinder 3, an auger 5 rotatably installed at the bottom of the feeding cylinder 3, a discharge hopper 21 fixedly installed on the side surface of the feeding cylinder 3, and a feeding mechanism set inside the feeding hopper 4 to ensure uniform feeding.

[0029] The feeding mechanism includes a rotating shaft 7 rotatably installed inside the feeding hopper 4, a first motor 6 fixedly installed on one side of the feeding hopper 4, and a uniform roller 8 rotatably installed inside the feeding hopper 4.

[0030] The output end of the first motor 6 passes through one side of the feeding hopper 4, and the output end of the first motor 6 is fixedly connected to one end of the rotating shaft 7. The rotating shaft 7 passes through the leveling roller 8 and is fixedly connected to the leveling roller 8.

[0031] When using this uniformly feeding screw feeder, first place the workbench 1 in an appropriate position, then add the material into the feed hopper 4, start the first motor 6, and its output drives the rotating shaft 7 and the uniform roller 8 to rotate. The rotation of the uniform roller 8 acts on the material in the feed hopper 4 to achieve stirring and uniform distribution. Through the rotation of the uniform roller 8, a fixed amount of material is added into the feed cylinder 3 each time, ensuring that the material falls smoothly into the feed cylinder 3. At the same time, the auger 5 rotates in the feed cylinder 3, evenly feeding the material out of the cylinder, thus ensuring the uniformity of feeding. During the feeding process, the material enters the feed cylinder 3 from the feed hopper 4, is pushed by the auger 5, and is finally discharged from the discharge hopper 21. The material is fully stirred and evenly distributed in the feed hopper 4, effectively avoiding blockage and accumulation of material during the feeding process, ensuring the continuity and uniformity of feeding, and reducing the possibility of local accumulation or compression of material into lumps.

[0032] Furthermore, in order to quickly disassemble and clean the auger 5, such as... Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, a fixed cylinder 12 is fixedly connected to the side surface of the feeding cylinder 3, and a connecting cylinder 9 is slidably connected to the side surface of the feeding cylinder 3. The inner wall of the connecting cylinder 9 is in contact with the side surface of the feeding cylinder 3, and the side surface of the connecting cylinder 9 is in contact with the inner wall of the fixed cylinder 12.

[0033] A second motor 10 is fixedly connected to one side of the connecting cylinder 9. The output end of the second motor 10 passes through the connecting cylinder 9 and is fixedly connected to one end of the auger 5. A handle 11 is fixedly connected to the side surface of the connecting cylinder 9. A limit groove 13 is opened inside the fixed cylinder 12. An insert block 14 is slidably connected inside the limit groove 13. A pull block 15 is fixedly connected to one side of the insert block 14.

[0034] Pull block 15 passes through limiting groove 13. A first spring 16 is provided inside the limiting groove 13. One end of the first spring 16 is fixedly connected to one side of the insert block 14, and the other end of the first spring 16 is fixedly connected to the inner wall of one side of the limiting groove 13. The connecting cylinder 9 has a slot 17 for inserting the insert block 14.

[0035] When using this uniformly feeding screw feeding device, if the auger 5 needs to be disassembled for cleaning, the user can pull the pull block 15. The pull block 15 causes the insertion block 14 to slide inside the limiting groove 13 and compress the first spring 16, causing the insertion block 14 to move out of the slot 17. At this time, the user can hold the handle 11, which causes the connecting cylinder 9 to slide on the side surface of the feeding cylinder 3, separating the connecting cylinder 9 from the feeding cylinder 3. Simultaneously, the connecting cylinder 9 drives the auger 5 and the second motor 10 to move, thereby causing the auger 5 to move out of the feeding cylinder 3, achieving quick disassembly of the auger 5 and facilitating user convenience. When cleaning the auger 5, the user can follow the reverse steps of disassembling the auger 5 as described above. At this time, the insert block 14 is inserted into the slot 17 under the elastic force of the first spring 16, limiting the connecting cylinder 9, so that the auger 5 can be stably installed inside the feeding cylinder 3. The screw feeding device with uniform feeding, through the cooperation of the fixed cylinder 12, connecting cylinder 9, second motor 10, handle 11, limiting groove 13, insert block 14, pull block 15, first spring 16 and slot 17, facilitates the quick disassembly of the auger 5, and thus facilitates the cleaning of the auger 5.

[0036] Furthermore, in order to reduce the impact force on the auger 5 when the material enters the feeding cylinder 3, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a second spring 18 is fixedly connected to the inner wall of the feeding cylinder 3. A clamping cylinder 19 is fixedly connected to the end of the second spring 18 away from the feeding cylinder 3. The side of the clamping cylinder 19 away from the second spring 18 is in contact with the side surface of the auger 5. A sponge pad 20 is fixedly connected inside the feeding cylinder 3. The auger 5 passes through the sponge pad 20.

[0037] When in use, the screw feeding device with uniform feeding function protects the auger 5 through the setting of the sponge pad 20, avoiding direct hard contact between the auger 5 and the inside of the feeding cylinder 3, thereby reducing the wear of the auger 5 during rotation and extending the service life of the auger 5. At the same time, the clamp 19 clamps the auger 5 under the elastic force of the second spring 18, reducing the impact force on the auger 5 and making the auger 5 more stable during rotation, reducing the shaking generated by the auger 5 during rotation.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
