Description

Technical Field

[0001] The invention relates to the technical field of rubber hose processing, in particular to a multi-layer composite ultra-low temperature resistant rubber hose and processing equipment thereof. Background Art

[0002] Rubber hoses are tubular rubber products made from rubber as the main raw material and used to transport gas, liquid, slurry or granular materials. Rubber hoses can be divided into four major categories: cloth-reinforced hoses, braided hoses, spiral hoses and other hoses. Cloth-reinforced hoses can be divided into three types according to usage conditions, working pressure and structure: pressure-resistant hoses, suction hoses (buried-wire type, exposed-wire type) and pressure-resistant suction hoses. Other hoses include full chemicalbook hoses, fire water hoses, rubber-plastic composite hoses HYL9Y12Y2L-MXF and special hoses. Special hoses include automobile radiator elbows, mud discharge hoses, various drilling hoses, heavy-duty suction and discharge hoses, etc., and are usually divided according to different usage conditions and performance. However, the existing technology still has some defects when preparing rubber hoses: The raw rubber used to prepare rubber hoses is usually mixed in a mixer. In existing technologies, the raw rubber is usually added directly into the hopper of the mixer, and the raw rubber and various additives are mixed evenly in the mixer. Since the raw rubber entering the mixer is not cut, it is difficult to be melted quickly in the mixer, resulting in a long mixing time for the raw rubber, which affects the mixing efficiency.

[0034] Working principle: When raw rubber needs to be mixed and processed, the operator first assembles the device on the mixer, with the discharge channel 14 vertically corresponding to the rubber hopper of the mixer, and then adds the raw rubber into the storage hopper 11; Subsequently, the operator starts the servo motor 37, and the drive shaft of the servo motor 37 rotates the No. 1 rotating roller 31, and the No. 1 rotating roller 31 rotates the transmission rod 25 through the No. 3 toothed pulley 38 and the No. 3 transmission toothed belt 39. The transmission rod 25 causes the sealing disk 21 to rotate 180 degrees through the incomplete gear 26, the driven gear 27, and the rotating shaft 22. At this time, the sealing disk 21 is staggered with the discharge chute hole 111, and the raw rubber in the storage hopper 11 is discharged downward through the discharge chute hole 111. The discharged raw rubber falls downward along the conical cover 121. When the incomplete gear 26 and the driven gear 27 are meshed again, the sealing disk 21 rotates 180 degrees again, and the sealing disk 21 coincides with the discharge chute hole 111. At this time, the raw rubber stops being discharged. At the same time, the No. 1 rotating roller 31 rotates the plurality of No. 1 cutting blades 311, which perform rough cutting on the raw rubber in the axial area of ​​the processing tank 1. The No. 1 rotating roller 31 causes one of the No. 2 rotating rollers 32 to rotate synchronously in the same direction via the No. 2 toothed pulley 35 and the No. 2 transmission toothed belt 36. One of the No. 2 rotating rollers 32 causes four No. 2 rotating rollers 32 to rotate synchronously in the same direction via four No. 1 toothed pulleys 33 and the No. 1 transmission toothed belt 34. The four No. 2 rotating rollers 32 cause the plurality of No. 2 cutting blades 321 to rotate synchronously. The plurality of No. 2 cutting blades 321 perform rough cutting on the raw rubber in the surrounding area of ​​the processing tank 1. The raw rubber after rough cutting falls into the receiving hopper 13 and then falls into the cavity 42 via the receiving hopper 13. At the same time, the No. 1 rotating roller 31 rotates the rotating seat 43, and the rotating seat 43 rotates the multiple annular blades 45. The multiple annular blades 45 finely cut the raw rubber entering the cavity 42. The raw rubber after fine cutting falls downward through the guidance of multiple guide rings 46 and is discharged downward through the discharge channel 14 into the rubber hopper of the mixer.
