Description

A feeding width controllable glue supply weight adjustment mechanism for an extruder

Technical Field

The utility model belongs to the technical field of weight regulating equipment, in particular to a feeding width controllable glue supply weight regulating mechanism for an extruder.

Background Art

The extruder is one of the important process equipment in the production of rubber products. The extruders currently on the market include: a rubber hot feeding device, a barrel, a discharge screw, a flange that can be connected to the extrusion die, and an extrusion die. A barrel is arranged below the rubber hot feeding device, a discharge screw is arranged in the barrel, a flange that can be connected to the extrusion die is arranged at one end of the barrel, and the extrusion die is connected to the flange. The rubber hot feeding device includes: a funnel-shaped feed barrel, a feed port is arranged at the upper end of the feed barrel, and a discharge port is arranged at the lower end of the feed barrel. The feed barrel is connected to the barrel through the discharge port. After the rubber compound after mixing enters the feed barrel, it is transported to the barrel from the discharge port. The discharge screw rotating in the barrel extrude and shear the rubber compound, and at the same time transports the rubber compound to the flange direction. The rubber compound extruded and sheared by the discharge screw enters the extrusion die through the flange. The rubber compound is extruded and formed while cooling in the extrusion die, thereby forming the desired product.

The rubber strips fed into the hot feed extruder must first be heat-refined in an open mixing mill. However, the current open mixing mill is unable to achieve a weight control process for the rubber strips fed into the extruder, resulting in weight fluctuations in the rubber strips fed into the extruder. The size of the extrudate is easily affected by the weight changes of the rubber strips, which in turn causes deviations in the size of the extrudate.

Through the rubber cutting knife mechanism 19 and the PLC module arranged in the extruder 3, the current of the extruder 3 is used as a judgment signal to judge whether the rubber consumption and rubber supply of the extruder 3 have reached a stable state. The first open mixer 17 performs a heat refining process of the rubber film. After the heat refining, it leads to the first conveyor belt 20 for the rubber film to be transported. The rubber film conveyor belt is driven by a motor to realize the conveying process of the rubber film. It arrives at the second open mixer 18 for secondary heat refining of the film. The current of the extruder 3 is used as a judgment signal, and the current value of the extruder 3 is transmitted to the PLC module as an input signal. The PLC module determines whether it is within the standard requirement range. If it is higher than the current standard requirement range, it is necessary to reduce the feed and reduce the width of the rubber film. The PLC transmits a signal to the cylinder 13 to drive the telescopic rod 12 to move forward, thereby causing the movable cutting knife 10 to move toward the fixed cutting knife 9, so that the width of the cut film is reduced until the PLC determines that the current of the extruder 3 meets the standard requirement range. If the PLC determines that the current is lower than the standard requirement range, it is necessary to increase the material supply and increase the width of the rubber film. The PLC transmits a signal to the cylinder 13 to drive the telescopic rod 12 to move backward, thereby making the movable cutting knife 10 move away from the fixed cutting knife 9, so that the width of the rubber film increases, until the PLC determines that the current of the extruder 3 meets the standard requirement range. The device is set in the open air, which is convenient for the operator to observe the reaction dynamics at any time, and is convenient for adjustment and maintenance.

Specifically, in the present embodiment, the rubber cutting knife mechanism 19 includes a scale rod 11 installed on the second mixing mill 18, on which a fixed cutting knife 9 and a movable cutting knife 10 are fixedly installed, and a cylinder 13 is arranged on the second mixing mill 18, on which a telescopic rod 12 is connected, and the action output end of the telescopic rod 12 is installed on the movable cutting knife 10, and the movable cutting knife 10 is connected to a movable sleeve 14, and a through hole 15 adapted to the scale rod 11 is provided on the movable sleeve 14, and a connecting port 16 is provided on the movable sleeve 14, and the connecting port 16 is connected to the action output end of the telescopic rod 12.

By arranging structures such as the scale rod 11, the cylinder 13 and the telescopic rod 12, the distance between the movable cutting knife 10 and the fixed cutting knife 9 can be intuitively observed through the scale rod 11, thereby achieving accurate control of the cut film width.
