Broken glue feeding rubber mixing technique

Abstract

The present invention relates to a cuttings-feeding rubber mixing technique, which belongs to the field of rubber-processing machines. The technique includes the following steps: (1) the storage of raw rubber, (2) the ripping of rubber blocks, (3) the weighing of cuttings, (4) the conveying of the cuttings, (5) the charging of the cuttings, (6) the mixing of the rubber material, (7) sheeting and cooling, (8) the stacking and storing of rubber sheets, (9) the granulating of the rubber sheets, (10) the mixing of rubber particles, (11) the weighing of the rubber particles, (12) the final mixing of rubber sheets, (13) sheeting and cooling, and (14) the stacking and storing of the rubber sheets. By the ripping of the rubber blocks, the granulating of the mother rubber sheets and two times of uniform mixings, the present invention realizes the uniform mixings of multiple batches of materials, so that the quality of the rubber material is more uniform and stable, and therefore the banburying effect is more ideal, and the following effects are achieved: The uniformity and stability of rubber mixing is improved, the efficiency of rubber mixing is increased, the impact damage of equipement is abated, and the automatization degree of material flowing is increased.

Description

technical field [0001] The invention belongs to the technical field of rubber processing, in particular to a crushed rubber feeding and mixing process, that is, the process of crushing and mixing the rubber material before putting it into a banbury mixer for rubber mixing. Background technique [0002] Rubber mixing is an important basic process in the rubber product industry. The quality of rubber mixing plays a vital role in the smooth production of semi-finished products in the subsequent process and the quality of final rubber products. The current domestic typical rubber mixing process is shown in Figure 1. The process is: raw rubber storage, rubber drying, block handling, block weighing, block feeding, rubber mixing, tablet cooling, stacking Sheet storage, film weighing, film final refining, sheet cooling and laminated sheet storage. This process has the following characteristics: [0003] 1. The raw rubber needs to be baked in advance: put the rubber block in the dr...

Problems solved by technology

The standard rubber blocks and smoked film packs need to be placed on pallets, sent into the drying room by a forklift, heated for a long time by steam and other heat sources, and finally fed by manual destacking, which is labor-intensive

[0004] 2. During the master batching, the rubber is put into the internal mixer in large pieces: the baked rubber blocks are semi-mechanically cut (some are not cut at all), and fed into the internal mixer in block form. Due to the crushing and dispersion process, the internal mixer Therefore, there is a large impact load on the internal mixer in an instant, and the rubber mixing cycle is increased; in addition, the stability of the quality of the mixed rubber is restricted by the quality stability of the original rubber.

[0005] 3. During the final refining, the masterbatch is put into the internal mixer in the form of film: the films are stacked and fed into the internal mixer, which has two disadvantages: one is that the rubber mixing cycle is long due to the crushing and dispersion of the film, and the other is the final mixing. Quality stability is restricted by masterbatch uniformity

[0006] The above traditional method is currently commonly used, and its characteristic is that in the process of master batching and final batching, the rubber material is fed in block and sheet form, which cannot be mixed in multiple batches, and requires pre-baking and semi-mechanized rubber cutting. The labor intensity is high, the impact damage to the internal mixer is large, the rubber mixing cycle is long, and the mixing uniformity is poor, which makes the quality of the mixed rubber difficult to stabilize. These problems can no longer be solved in the traditional rubber mixing process. big problem
