Description
Technical field
The invention belongs to refining glue technical field more particularly to a kind of material automatic weighing device, its application and material are automatic
Weighing technique.
Background technology
In mixing process, the big blob of viscose of raw rubber is cut into after fragment and carries out mixing and can effectively reduce energy consumption, is substantially saved
The energy；It carries out mixing after the natural gum of multiple batches is shredded to mix thoroughly, then input is kneaded, and can effectively promote the performance of rubber compound
Stability improves the quality of rubber product.
More efficient raw rubber crumbling method is to use raw rubber crusher at present, and broken glue amount can will be marked up to 8 tons per hour
Quasi- raw rubber is broken into average 60~100 grams of rubber block, but it is more than 200 also to have the rubber block weight of significant proportion (more than 10%)
Gram.Simultaneously for prevent broken rubber block adhesion need to be added together, in shattering process a certain proportion of white carbon be used as every
From agent.
Traditional banburying process is that the title before mixer is transported to manually or by some automated tools by standard raw rubber block
It measures on belt, needs manually to cut glue progress counterweight to reach recipe requirements also.After raw rubber crushing process, tradition has also been continued to use substantially
The operation mode of banburying process, i.e., by broken rubber block by artificial or Belt Conveying to mixer before, by manually controlling
System input weighs the sizing material weight of belt to complete dispensing.
Since human factor is more, the stability of weighing accuracy cannot be guaranteed, simultaneously because the problem of interleaving agent, need
Reliable dust pelletizing system, otherwise site environment will deteriorate, threaten operator's health.Because each board is required for above-mentioned
Sizing material conveying device or storage device, belt conveyer scale, dust-extraction unit etc., on-the-spot meeting is more crowded, and device layout is difficult.
To solve the above problems, a kind of new proportioning process can be used, i.e., except mixing workshop according to the production schedule and
Recipe requirements are automatically performed weighing and the dispensing of sizing material by computer control system, are then sent to each close by logistics system
Mill platform carries out weight verification and dosing operation.The technological process in the patent of invention application No. is 201110148674.2
There is similar description, is not repeated.It realizes that above-mentioned technique, a crucial problem are the automatic weighings of rubber, to meet close
The productive temp of 3 minutes an or so vehicles of mill, weighing speed are had to soon；Meet technical recipe requirement, weighing accuracy is certain
It is enough high, it is more than 200 grams of sizing material for often there is rubber block weight, makes weighing accuracy control at ± 200 grams, even more
Height is difficult to realize, while the problems such as also need to consider dedusting.The prior art including above-mentioned patent not at
Ripe rubber block automatic weighing solution.
