Description

Technical Field

[0001] The utility model belongs to the technical field related to the production of rubber additives, in particular to a granulator for rubber additives. Background Art

[0002] Rubber additives refer to the general term for rubber additives added during the processing of natural rubber or synthetic rubber into rubber products, which are used to give rubber products performance and ensure the service life of rubber products. Rubber additives are important auxiliary raw materials in the rubber industry. Rubber additives can improve the performance of rubber and make rubber more applicable. After the production of rubber additives is completed, the finished product needs to be granulated by a granulator to facilitate the subsequent use of rubber processing and ensure work balance. However, it still has the following disadvantages in actual use:

[0003] 1. When the rubber additive granulator is working, the additive raw materials are directly transported into it for granulation. During the granulation process, when the granulation equipment transports the rubber additive raw materials, due to the excessive amount of rubber additive input during the transportation process, it may cause blockage and affect the smoothness of the input granulation;

[0004] 2. When the rubber additive granulator is working, after the additive raw materials are granulated, they need to be transported to the drying product line so that the particles made of the rubber additive raw materials are dried and fully formed. During the forming process, the operation process is relatively long, and it is not convenient to dry the rubber additive particles during work. Utility Model Content

Specific embodiment 1

[0025] See also Figure 1-5 The utility model is a granulator for rubber additives, comprising a conveying cylinder 1, a conveying bucket 2, an arc plate 3 and a motor 4. One end of the upper peripheral side of the conveying cylinder 1 is fixedly connected with the conveying bucket 2. The top of the conveying bucket 2 is connected with a device for conveying rubber additives to convey the processed rubber additives into the conveying cylinder 1. An arc plate 3 is symmetrically fixed at one end of the conveying cylinder 1 away from the conveying bucket 2. The arc plate 3 connects a ventilation net 301 thereto. The upper and lower parts between the two arc plates 3 are both fixed with ventilation nets 301. A ventilation cavity 3 is fixed between the two arc plates 3 above and below the ventilation net 301. 05, dry high-pressure air is transported from the bottom to the conveying cylinder 1 through the ventilation cavity 305 through the ventilation net 301, and after the rubber additive particles are dried in the conveying cylinder 1, they are transported to the upper ventilation cavity 305 through another ventilation net 301. The two arc plates 3 and the two ventilation nets 301 are fixed with sealing disks 302 at one end away from the conveying cylinder 1. The arc plates 3 and the ventilation nets 301 are sealed at one end away from the conveying cylinder 1 through the sealing disk 302. The outer side of the sealing disk 302 away from the end of the arc plate 3 is provided with a motor 24, and the rotating shaft 2 401 is driven to rotate by the motor 24.

[0026] Specifically, a motor 101 is fixed to the end of the conveying cylinder 1 away from the arc plate 3, and a rotating shaft 102 is fixed to the output end of the motor 101. The rotating shaft 102 is movably connected in the conveying cylinder 1, and a spiral blade 103 is fixed to the circumference of the rotating shaft 102 in the conveying cylinder 1. Extrusion holes 104 are formed in a circular array on the outer side of the rotating shaft 102 at the end of the conveying cylinder 1 away from the motor 101. The conveying cylinder 1 drives the rotating shaft 102 to rotate through the motor 101, and drives the spiral blade 103 to rotate. When the spiral blade 103 rotates, the rubber additive raw material entering the conveying cylinder 1 is transported to the position of the extrusion hole 104 therein, and is extruded between the two arc plates 3 through the extrusion hole 104.

[0027] Furthermore, a driving motor 201 is fixed to one side of the lower part of the conveying bucket 2, and a driving shaft 202 is fixed to the output end of the driving motor 201. The driving shaft 202 is movably connected to one side of the conveying bucket 2, and a flipping frame 203 is fixed to the end of the driving shaft 202 away from the driving motor 201.

[0028] The operation process of this embodiment is as follows: during operation, after the rubber additive material is transported to the conveying bucket 2, the driving motor 201 is started, and the driving motor 201 drives the driving shaft 202 to rotate. When the driving shaft 202 rotates, the flipping frame 203 is driven to rotate, and the rubber additive raw material in the conveying bucket 2 is flipped, so that the rubber additive raw material is stably transported to the conveying cylinder 1. At the same time, the motor 101 is started, and the conveying cylinder 1 drives the rotating shaft 102 to rotate through the motor 101, and drives the spiral blade 103 to rotate.

At the same time, the air delivery pipe 306 on the ventilation cavity 305 at the lower part of the arc plate 3 is connected to the pipeline for delivering high-pressure air. The dry high-pressure air is conveyed to the ventilation cavity 305, and passes through the ventilation net 301 near the west of the curved plate 3 to the space between the two curved plates 3 to dry the rubber additive particles. The air delivery pipe 306 on the ventilation cavity 305 at the upper part of the curved plate 3 is connected with the pipeline for outputting air. The air for drying the rubber additive particles between the two curved plates 3 passes through the upper ventilation net 301 and is conveyed to the upper ventilation cavity 305, and then conveyed to the air delivery pipe 306. The air after drying the rubber additive is output, so that the rubber additive is fully dried.
