Technical Field

The utility model relates to the field of machinary, specifically a plastic processing machinery.

Background

In the technical field of steel coil packaging, the protective plate made of PE (polyethylene) is often treated as waste after being used up, which not only increases the cost, but also is not environment-friendly; if the waste materials are processed into the guard plate after being crushed and granulated, the technical index required by the guard plate can not be reached, therefore, in order to solve the technical problem, people adopt a composite structure, namely a layer of PP (polypropylene) plate is compounded on the guard plate processed by the waste materials; however, when PP and PE are directly compounded, the melting point of PP is 189 ℃, the extrusion temperature of regenerated PE is generally 130-150 ℃, and the melting point of PE is 110-115 ℃, so that the melting point of PP is not reached, and the compounding of PP and PE cannot be ensured; the prior art adopts a bonding mode to compound the two components, but the method has poor strength, is easy to cause the separation of the two components when in use and can not meet the use requirements.

In order to solve the technical problem, the applicant sets a PE-EVA mixing layer as an intermediate layer, firstly, the PE (polyethylene) -EVA (ethylene-vinyl acetate copolymer) mixing layer is heated to 310-340 ℃, and then is sprayed on a PP layer, so that the PE-EVA mixing layer and the PP layer are firstly compounded into a whole; then, the PE-EVA layer is utilized to have a lower melting point, generally only about 99 ℃, so that the temperature of the extrusion end of the regenerated PE reaches the melting point temperature, and finally, the regenerated PE layer and the PP layer which is compounded previously are perfectly compounded into a whole under the action of an upper extrusion roller and a lower extrusion roller only depending on the temperature of the extrusion end. Therefore, an extrusion compounding machine needs to be designed.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model aims to provide an extrusion compounding all-in-one machine, which comprises a frame, wherein a feeding roller and a steering roller are arranged above the frame, and a temperature adjusting roller, an upper extruding roller and a lower extruding roller are sequentially arranged below the steering roller from top to bottom; the outlet of the extrusion die of the extruder corresponds to one side of the extrusion part of the upper extrusion roller and the lower extrusion roller; the rear end of the extruder is provided with a feed hopper; the other side of the extrusion part is provided with a discharging inclined plane, and a cutter is arranged above the discharging inclined plane; the tail end of the discharging inclined plane is provided with a collecting roller; the temperature adjusting roller, the upper extrusion roller and the lower extrusion roller are all hollow rollers, and the hollow rollers are connected with the heating water tank through water pipes; the heating water tank is internally provided with a heating element and a temperature sensor. The PP film sprayed with the PE-EVA mixing layer passes through the steering roller from the discharging roller, bypasses the temperature adjusting roller and the upper extrusion roller, and is compounded with the PE plate at the outlet of the extruder die into a whole under the action of the upper extrusion roller and the lower extrusion roller. According to the needs, a plurality of guard plates with certain width are formed by the cutter, and are wound and collected after reaching the collecting roller along the discharging inclined plane.

The structure of the cutter can ensure the adjustment of the clearance between the hob and the guard plate so as to adapt to the requirements of guard plates with different thicknesses. The cutter is including fixing the support in the frame, sets up the slide in the support, sets up the slider in the slide, and the slider is inside to be set up the screw, and the screw rod is connected with the screw, and the upper end of screw rod is fixed with driving motor's output shaft. A tool rest is fixed on the sliding block, and a hob is arranged below the tool rest.

A platform, a discharging roller and a steering roller are arranged above the rack; a ladder stand is arranged below the platform.

The discharging roller, the temperature adjusting roller, the upper extrusion roller, the lower extrusion roller and the collecting roller are all connected with respective driving motors through gear reducers, and all the motors, the heating elements and the temperature sensors are all connected with a control console.

The utility model has the advantages that: the regenerated PE layer and the PP layer which is previously compounded are perfectly compounded into a whole under the action of the upper and lower extrusion rollers only depending on the temperature of an extrusion end. The requirement of batch production is met, the product quality is good, and the layers are completely compounded into a whole.
