Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing processing, in particular to a rubber mixing device. Background Art

[0002] Rubber mixing equipment is a device used for rubber mixing or internal mixing. Its purpose is to mix rubber raw materials with various additives evenly so as to obtain ideal rubber product performance in subsequent processing. The internal mixing process includes rubber pretreatment, mixing, extrusion and other steps.

[0003] The existing rubber mixing equipment on the market cannot crush the raw materials to qualified standards at one time during processing, so it is necessary to manually crush the materials repeatedly many times until they are qualified and then mix them. This will affect the processing efficiency during the mixing process. For this reason, we propose a rubber mixing equipment. Utility Model Content

[0024] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0025] A rubber mixing equipment comprises a mixing box 1, wherein two cutting rollers 2 are arranged side by side at the upper end of the mixing box 1, a vibrating screen plate 3 is arranged just below the bottom end of the mixing box 1 near the cutting rollers 2, and a conveying box 4 is fixedly installed on the right side of the mixing box 1; a circulation mechanism 5 is arranged inside the conveying box 4, and the circulation mechanism 5 comprises a third motor 501, an auger 502 and a material discharge chute 503, and the material discharge chute 503 is arranged between the mixing box 1 and the bottom end of the conveying box 4; a discharge chute 13 is arranged at the bottom end of the mixing box 1 away from the second motor 11, and a loading port 14 is arranged at the top end of the mixing box 1; a third motor 501 is fixedly installed on the outer side of the bottom end of the conveying box 4, an auger 502 is arranged at one end of the output shaft of the third motor 501, and the auger 502 is movably connected to the inside of the conveying box 4, and a reflux chute 6 is arranged between the conveying box 4 and the top end of the mixing box 1;

[0026] In this embodiment, after the material is crushed, it falls on the vibrating screen plate 3. After being vibrated and screened by the vibrating screen plate 3, the qualified materials fall into the inner bottom end of the mixing box 1, and the unqualified materials enter the conveying box 4 from the discharge chute 503. At this time, the third motor 501 is started. After the third motor 501 is started, it drives the auger 502 inside the conveying box 4 to rotate. After the auger 502 rotates, the entering material is lifted and sent to the upper end of the mixing box 1 from the reflux chute 6 for repeated crushing. In this way, the crushed materials can be automatically circulated during processing.

[0027] like Figure 2As shown, a transmission housing 7 is fixedly installed on the outside of the mixing box 1 away from the conveying box 4, and a driving gear 8 and a driven gear 9 are respectively arranged at both ends of the inside of the transmission housing 7, and the driving gear 8 is meshed with the driven gear 9. A first motor 10 is arranged on the outside of the side of the transmission housing 7 close to the driving gear 8, and the output shaft of the first motor 10 is fixedly connected to the driving gear 8, and the driving gear 8 and the driven gear 9 are respectively connected to two cutting rollers 2 at one end away from the first motor 10; a second motor 11 is fixedly installed on the outside of the bottom end of the side of the mixing box 1 close to the conveying box 4, and the output shaft of the second motor 11 is located at the bottom end of the mixing box 1, and a stirrer 12 is arranged;

[0028] In this embodiment, when part of the material is ready for crushing and cutting, it immediately falls into the lower part of the internal mixing box 1. At this time, the second motor 11 can be controlled to start. After the second motor 11 is started, it drives the agitator 12 at the bottom end of the internal mixing box 1 to rotate. After the agitator 12 rotates, the material is mixed and processed. In this way, mixing can be continued while crushing and screening, without stopping and waiting.

[0029] like Figure 2 As shown, a frame 15 is fixedly installed on the outside of the bottom ends of both sides of the mixing box 1;

[0030] In this embodiment, the racks 15 disposed on both sides of the internal mixer box 1 are used to support the internal mixer box 1 off the ground, so as to facilitate unloading of materials from the position of the discharge chute 13 .

[0031] Working principle: During processing, the material to be mixed is put in from the feeding port 14, and then the first motor 10 is started. After the first motor 10 is started, it drives the driving gear 8 to rotate, and the driving gear 8 drives the driven gear 9 meshing on the other side to rotate in the opposite direction, thereby controlling the two cutting rollers 2 to quickly cut and crush the incoming material. After the material is crushed, it falls on the vibrating screen plate 3. After being vibrated and screened by the vibrating screen plate 3, the qualified material falls into the inner bottom end of the mixing box 1, and the unqualified material enters the conveying box 4 from the discharge chute 503. At this time, the third motor 501 is started. After the third motor 501 is started, it drives the auger 502 inside the conveying box 4 to rotate. After the auger 502 rotates, it lifts the incoming material and sends it to the upper end of the mixing box 1 from the reflux chute 6 for repeated crushing; as the material is continuously crushed and screened, the second motor 11 is started at this time. After the second motor 11 is started, it drives the agitator 12 at the inner bottom end of the mixing box 1 to rotate, and the agitator 12 rotates to mix the material.
