The utility model relates to the technical field of rubber
processing equipment, in particular to rubber sealing ring material accurate proportioning and mixing equipment which comprises a support frame, a mixing
barrel, a storage
barrel, a mixing device, a batching device, a discharging device, a conveying device and an opening and closing device, the mixing
barrel is rotatably mounted in the support frame, the mixing device is mounted in the mixing barrel, and the discharging device is mounted in the storage barrel. The discharging device is installed on the side wall of the supporting frame, materials in the
material storage barrel are conveyed into the feeding hopper, the weight of the raw materials in the feeding hopper is monitored in real time through the weighing sensor, when a set value is reached, feeding is stopped, the weighing sensor monitors the weight of each
raw material in real time, and the discharging device is used for discharging the raw materials. Required raw materials are proportioned in the feeding hopper in an accumulative weighing mode, the consistency of product quality is remarkably improved, after proportioning is completed, the
electromagnetic valve on the discharging
pipe is opened, meanwhile, the sealing plate is opened through the opening and closing device, and the materials in the feeding hopper enter the feeding frame below through the discharging
pipe.
