Description

A mill feeding device

technical field

The utility model relates to the field of mills, in particular to a mill feeding device.

Background technique

The open mill plasticizes the raw rubber. It throws the raw rubber block between two cylinders, and the molecular chain of the rubber is stretched and broken by the friction of the spoke cylinder, so that the rubber can obtain plasticity. Use open mixer for masticating, and its masticating temperature is usually controlled below 100°C. This mastication method belongs to low-temperature mechanical mastication. The advantages of open mill mastication are that the plasticity of the plasticized rubber is uniform and the thermoplasticity is small; the shrinkage performance of the obtained rubber is small; the process flexibility of the equipment is strong, the applicable surface is wide (various types of rubber, etc.), and the investment is small.

The material cutting knife of the current mill feeding device is a plane cutting knife that cuts vertically downward. When the material conveying mechanism transports the material to the cutting knife, it needs to stop and wait for cutting. The work efficiency is low, the cutting is uneven, and the conveying mechanism walks Stop and go, shorten the service life. The conveying mechanism is generally arranged horizontally, which may easily cause the accumulation of rubber to affect the cutting effect. At the same time, the conveying mechanism placed horizontally occupies a large area and requires a large space for placement.

Utility model content

The utility model provides a mill feeding device, the purpose of which is to mainly overcome the problems of uneven material accumulation and cutting and low feeding efficiency of the existing mill feeding device, and the shortcomings of being unable to cut while conveying materials .

In order to solve the problems of the technologies described above, the technical scheme of the utility model is as follows:

A feeding device for an open mill, comprising a frame, a cutting mechanism arranged on the frame, and a conveying mechanism arranged on the frame to transport materials to the cutting mechanism for cutting, and the cutting mechanism includes vertically arranged A cutting knife and a clamping roller, the cutting knife includes a roller shaft and a spiral blade arranged on its surface, the edge of the spiral blade is in rolling contact with the outer surface of the clamping roller, and the cutting mechanism is arranged on the conveyor end of the mechanism, and the transmission speed of the transmission mechanism is the same as the rotation speed of the cutting mechanism.

The transmission mechanism includes a conveyor belt and a roller that drives the conveyor belt. The first and second rollers are arranged at the head end and the end of the conveyor belt respectively, and a third roller is arranged in the middle of the work table between the first and second rollers. roller and fourth roller.

It also includes a pressing roller, a bracket in the shape of a door across the left and right ends of the worktable is arranged between the first roller shaft and the third roller shaft, and two suspension rods are arranged in parallel and vertically in the middle of the bracket. A rotating shaft is arranged between the two supporting frames of the bracket, and a rectangular frame is arranged on the side of the rotating shaft, and a rectangular parallelepiped connecting rod is arranged in the middle of the rectangular frame parallel to the rotating shaft, and the connecting rod is connected with the suspension rod. The other horizontal bar of the rectangular frame parallel to the rotating shaft has two pie-shaped pressing rollers arranged vertically at intervals.

The conveying mechanism is arranged obliquely upward.

From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the advantages that: the cutting knife of the spiral blade is driven by the roller shaft to rotate and cut, and the material delivered to the cutting knife by the conveying mechanism is cut. The spiral cutting knife rotates synchronously with the transmission mechanism, and cuts while feeding, forming a flow operation, and the transmission mechanism does not need to wait for cutting. The inclined upward arrangement of the conveying mechanism not only saves the space for placing the equipment, but also stretches the material upwards to prevent the spiral blade cutter from being blocked by the material, causing the conveying mechanism to stop working. This kind of mill feeding device improves the feeding efficiency and makes the material cutting more uniform.
