Description

Technical Field

[0001] This utility model relates to a reclaimed rubber feeding device for stable material discharge. Background Technology

[0002] In the processing and production of reclaimed rubber, the feeding device is a crucial component. Traditional feeding devices typically employ a single conveying method, such as a screw feeder or a vibrating feeder. While these devices can meet production needs to some extent, they also have some shortcomings.

[0003] Materials like reclaimed rubber, which have a certain viscosity and flowability, are prone to clumping in the hopper due to prolonged accumulation, moisture absorption, or temperature changes. Once large clumps of reclaimed rubber form, they not only affect the efficiency of subsequent processing but may also clog the feeding pipes, severely impacting the continuity and stability of production. Utility Model Content

[0004] The main objective of this invention is to provide a stable reclaimed rubber feeding device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A stable discharge reclaimed rubber feeding device includes a hopper, a feeding pipe below the hopper, a spiral shaft inside the feeding pipe, a spiral motor at one end of the spiral shaft outside the feeding pipe, a stirring shaft horizontally arranged inside the hopper, a stirring motor at one end of the stirring shaft outside the hopper, and a distribution column above the stirring shaft inside the hopper.

[0007] Preferably, there are two stirring shafts, which are spaced apart inside the hopper.

[0008] Preferably, the blades of the two stirring shafts are staggered.

[0009] Preferably, there are four material distribution columns, which are arranged in a cross-shaped structure.

[0010] Preferably, a material distribution chain is provided between two adjacent material distribution columns.

[0011] Preferably, the two ends of the material distribution chain are connected to the connection center of the four material distribution columns and the turning point of the inner wall of the hopper, respectively.

[0012] Preferably, the hopper is provided with through holes through which both ends of the stirring shaft pass.

[0013] Preferably, a bearing is connected to the other end of the stirring shaft, and a bearing mounting box is provided on the outer wall of the hopper.

[0014] Preferably, the end of the feeding pipe is provided with a discharge pipe.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] This invention provides a hopper equipped with a distribution column and a stirring shaft for processing reclaimed rubber. When the reclaimed rubber is fed into the hopper, the distribution column first breaks down large pieces of the adhesive into smaller chunks. These smaller chunks are then further dispersed by the stirring shaft, ensuring they flow smoothly into the feeding pipe. Finally, a screw shaft transports the material upwards to other equipment. This design effectively prevents the reclaimed rubber from clogging the hopper outlet, ensuring a smooth feeding process. Attached Figure Description

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-5 As shown, the stable discharge reclaimed rubber feeding device provided in this embodiment includes a hopper 1, a feeding pipe 2 is provided below the hopper 1, a spiral shaft 3 is provided inside the feeding pipe 2, a spiral motor 4 is provided at one end of the spiral shaft 3 outside the feeding pipe 2, a stirring shaft 5 is horizontally provided inside the hopper 1, a stirring motor 6 is provided at one end of the stirring shaft 5 outside the hopper 1, and a material distribution column 7 is provided inside the hopper 1 above the stirring shaft 5.

[0025] After the reclaimed rubber enters the hopper 1, it first passes through the distribution column 7. The distribution column 7 can divide the large pieces of reclaimed rubber into smaller pieces or strips. After being divided by the distribution column 7, the small pieces of reclaimed rubber are further crushed and dispersed under the action of the stirring shaft 5, keeping them in a loose state. After falling into the feeding pipe 2, the screw shaft 3 is responsible for continuously and stably conveying the reclaimed rubber to the next process. The entire feeding device ensures the normal and efficient feeding of reclaimed rubber, improving the reliability of the equipment and the production efficiency.

[0026] In this embodiment, as Figure 5 As shown, there are two stirring shafts 5, which are spaced apart inside the hopper 1. The dual stirring shaft design can more comprehensively cover the recycled rubber in the hopper 1, ensuring that the recycled rubber is evenly dispersed and avoiding dead corners.

[0027] In this embodiment, as Figure 5 As shown, the blades of the two stirring shafts 5 are staggered. The staggered blades can form a more complex flow path when rotating, which helps to further break up the bonded reclaimed adhesive and reduce the possibility of clogging.

[0028] In this embodiment, as Figure 5 As shown, there are four material distribution columns 7, which are arranged in a cross shape. The cross-shaped distribution of the material distribution columns 7 can effectively divide large pieces of recycled rubber into smaller pieces and improve the dispersing effect.

[0029] In this embodiment, as Figure 5 As shown, a material distribution chain 8 is provided between two adjacent material distribution columns 7. The material distribution chain 8 can assist the material distribution column 7 in dividing the recycled rubber, and at the same time play a certain role in guiding the flow, further improving the material distribution effect and reducing the risk of blockage.

[0030] In this embodiment, as Figure 2 As shown, the two ends of the material distribution chain 8 are respectively connected to the connection center of the four material distribution columns 7 and the turning point of the inner wall of the hopper 1, ensuring the connection stability of the material distribution chain 8 so that it is not easy to fall off or shift during the operation, thereby ensuring the continuity and stability of the material distribution effect.

[0031] In this embodiment, as Figure 4 As shown, the hopper 1 is provided with through holes 9 for both ends of the stirring shaft 5 to pass through, so that the stirring shaft 5 can be smoothly installed and fixed on the hopper 1, while allowing the stirring shaft 5 to rotate freely, thereby realizing the stirring function of the recycled rubber.

[0032] In this embodiment, as Figure 5 As shown, the other end of the stirring shaft 5 is connected to a bearing 10, and a bearing mounting box 11 is provided on the outer wall of the hopper 1, which provides protection and fixation for the bearing 10 and ensures the stable operation of the stirring shaft 5.

[0033] In this embodiment, as Figure 1 As shown, the end of the feeding pipe 2 is provided with a discharge pipe 12, which allows the recycled rubber to be smoothly discharged from the feeding pipe 2 and enter the next process or equipment.

[0034] In summary, in this embodiment, the hopper 1 is equipped with a distribution column 7 and a stirring shaft 5 for processing reclaimed rubber. When the reclaimed rubber is fed into the hopper 1, the distribution column 7 first breaks down large pieces of adhesive into smaller pieces. These smaller pieces are then further dispersed by the stirring shaft 5, ensuring they fall smoothly into the feeding pipe 2. Finally, the screw shaft 3 conveys the material upwards to other equipment. This design effectively avoids the problem of reclaimed rubber clogging the outlet of the hopper 1 due to adhesion, ensuring a smooth feeding process.

[0035] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
