Description

Technical Field

[0001] This utility model relates to the field of polymer material processing technology, and in particular to a feeding device for producing composite flame retardants. Background Technology

[0002] Flame retardants are substances used to improve the fire resistance of materials, that is, additives that prevent materials from burning and inhibit the spread of flames. In the process of processing flame retardants, feeding devices are required.

[0003] For example, there is a feeding device for producing composite flame retardants, with publication number CN215849136U. The guide rod is L-shaped. When feeding is required, the material is placed into the material cylinder, and the motor inside the material cylinder is started. The motor drives the propeller and the cross plate to rotate through the transmission shaft, so that the propeller and the cross plate stir the material in the material cylinder, making the material evenly mixed. There is no need for manual pre-mixing of materials, thereby shortening the operation time and improving work efficiency. Then, the electric push rod on the connecting plate is started, so that the electric push rod pushes the moving block and the first rotating shaft to rise. This causes the first rotating shaft to drive the material cylinder to rise, so that the material cylinder moves along the guide rod through the first rotating shaft and the second rotating shaft. When the second rotating shaft on the material cylinder moves to the top of the guide rod, the material cylinder will tilt as the first rotating shaft continues to rise, achieving the purpose of automatically lifting the material.

[0004] In this device, because the guide rod is L-shaped, the material cylinder can only tilt to a horizontal position after it moves to the top of the guide rod. This results in the material inside the cylinder not being completely emptied, especially for larger particles, which are prone to remain at the bottom of the cylinder wall and require manual cleaning, increasing operating costs.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figure 1-4 As shown, a feeding device for producing composite flame retardants includes a material cylinder 9 and a base 1. A rotating disk 2 is rotatably connected to the top of the base 1, and a support frame 17 is fixedly connected to the top of the rotating disk 2. A slider 5 is slidably connected inside the support frame 17. An insert rod 6 passes through the side of the slider 5. One end of the insert rod 6 is fixedly connected to a mounting bracket 8 for mounting the material cylinder 9. A discharge port 18 is opened at the bottom of the material cylinder 9. A blocking plate 12 is provided inside the discharge port 18. An electric push rod 7 is fixedly connected to the central axis at the top of the material cylinder 9. The telescopic end of the electric push rod 7 is connected to the blocking plate 12. A sleeve 10 is rotatably connected to the outside of the electric push rod 7 and a plurality of evenly distributed stirring rods 11 are fixedly connected to the outside of the sleeve 10. The bottom of the material cylinder 9 is shaped like a frustum.

[0025] In this technical solution, the frustum-shaped bottom concentrates the material inside the cylinder 9 towards the discharge port 18, reducing material residue. Combined with the opening and closing of the blocking plate 12, the material can be discharged more thoroughly, avoiding manual cleaning and reducing operating costs. Specifically, the electric push rod 7 retracts, driving the blocking plate 12 to rise. During the rising process, the blocking plate 12 separates from the inner wall of the cylinder 9, creating a gap between the blocking plate 12 and the inner wall of the cylinder 9, thus facilitating the material to fall. By setting the sleeve 10 and the stirring rod 11, the rotation of the sleeve 10 drives the stirring rod 11 to rotate, thereby stirring the material inside the cylinder 9.

[0026] like Figure 2As shown, an electric push rod 7 is also fixedly connected to one side of the slider 5, and the telescopic end of the electric push rod 7 located on one side of the slider 5 is fixed to the other end of the plug rod 6.

[0027] In this technical solution, an electric push rod 7 is provided on one side of the slider 5. When its telescopic end extends or retracts, it drives the insertion rod 6 to slide relative to the slider 5, which facilitates the adjustment of the horizontal position of the mounting frame 8, thereby making it easier to control the feeding position.

[0028] like Figure 3 As shown, a gear 16 is rotatably connected to one side of the top of the material cylinder 9, and a gear ring 15 is sleeved on the outside of the sleeve 10. The gear 16 meshes with the gear ring 15. A motor 3 is fixedly connected to one side of the top of the material cylinder 9, and the main shaft of the motor 3 located on one side of the top of the material cylinder 9 is fixed to the gear 16.

[0029] In this technical solution, the motor 3 drives the gear 16 to rotate, and the gear 16 meshes with the toothed ring 15 on the outer side of the rotating sleeve 10, thereby driving the rotating sleeve 10 and the stirring rod 11 to rotate and stir the composite flame retardant raw materials in the material cylinder 9. The main shaft of the motor 3 is fixed to the gear 16 after penetrating the top wall of the material cylinder 9.

[0030] like Figure 4 As shown, an extension sleeve 19 is fixedly connected to the outside of the discharge port 18, and a support rod 14 distributed along the horizontal line is fixedly connected to the inside of the extension sleeve 19. A telescopic sleeve 13 is rotatably connected to the top of the support rod 14. The telescopic end of the telescopic sleeve 13 is fixed to the blocking plate 12. A motor 3 is also fixedly connected to the bottom of the support rod 14. The main shaft of the motor 3 located at the bottom of the support rod 14 is fixed to the telescopic sleeve 13.

[0031] In this technical solution, during the unloading process, the telescopic sleeve 13 can assist in supporting the blocking plate 12. It rotates to drive the blocking plate 12 to rotate and clean the residual material on the blocking plate 12. The motor 3 spindle located at the bottom of the support rod 14 is connected to the support rod 14.

[0032] like Figure 2 As shown, a motor 3 is also embedded in the middle of the base 1. The main shaft of the motor 3 located inside the base 1 is fixed to the center of the rotating disk 2. A lead screw 4 that is threadedly connected to the slider 5 is rotatably connected inside the support frame 17. A motor 3 is also fixedly connected to the top of the base 1. The main shaft of the motor 3 located at the top of the base 1 is fixed to one end of the lead screw 4.

[0033] In this technical solution, the motor 3 drives the rotating disk 2 to rotate around the central axis of the base 1, which in turn drives the support frame 17, the material cylinder 9 and other components to rotate synchronously, so as to realize the 360° rotation of the material cylinder 9 in the horizontal direction, which is convenient for connecting multiple feeding stations or reaction equipment. In addition, by setting the motor 3 on the top of the base 1, when the motor 3 controls the screw 4 to rotate, the slider 5 slides up and down along the guide rail of the support frame 17 due to the thread transmission, thereby adjusting the vertical height of the material cylinder 9.

[0034] Working principle: When in use, after the material is poured into the material cylinder 9, the motor 3 at the top of the base 1 drives the lead screw 4 to rotate, causing the slider 5 to slide and rise within the support frame 17. Then, the motor 3 embedded in the middle of the base 1 drives the rotating disk 2 to rotate, causing the support frame 17 to rotate and rotate the material cylinder 9 to the top of the reaction equipment. After that, the electric push rod 7 on the side of the slider 5 pushes the insertion rod 6 to move the material cylinder 9 fixed by the mounting frame 8 horizontally to further adjust its position. The motor 3 at the top of the material cylinder 9 drives the rotating sleeve 10 and the stirring rod 11 to rotate and stir the material through the gear 16 meshing with the gear ring 15. When discharging the material, the electric push rod 7 at the top of the material cylinder 9 extends and retracts, causing the blocking plate 12 to rise. During the rising process, the blocking plate 12 separates from the inner wall of the material cylinder 9 from the contact state, creating a gap between the blocking plate 12 and the inner wall of the material cylinder 9, thereby allowing the material to fall.

[0035] The wiring diagrams of the motor 3 and electric push rod 7 in this utility model are common knowledge in the field, and their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor 3 and electric push rod 7 will not be explained in detail.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
