Description

Rim charge reflux device for extruder
Technical Field
The utility model relates to a processing tool technical field, in particular to an edge-trim reflux unit for extruder.
Background
Extruded products are generally produced by means of an extruder, the remaining scrap being used as scrap in order to obtain a finished material web with smooth edges. The initial edge material is required to be wound on an edge material winding wheel manually during edge material winding, manual discharging is required after the edge material is wound for about 20-40 minutes (the time depends on the product specification), then the edge material is wound on the winding wheel, and the steps are repeated. The method wastes manpower seriously, and the leftover materials are required to be crushed by special persons in the follow-up process, so that the leftover materials are polluted in different degrees, and the follow-up recycling is a hidden trouble. In another method, a pulverizer with a traction wheel is used for direct pulverization, so that part of manpower can be saved, and manual unloading and packaging are needed after pulverization.
Therefore, there is a need for an improved structure to solve the above problems.
Disclosure of Invention
The utility model discloses a main aim at provides an edge-trim reflux unit for extruder can save the manpower and the time of retrieving the edge-trim.
The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides an rim charge reflux unit for extruder for have a main hopper, a screw feeder, one extrude the head, three extrude the roller, a plurality of tension roller and a wind-up roll's extruder, be equipped with between the tension roller and be used for will extruding the sheet and cut into the cutting sword of finished product material area and rim charge, rim charge reflux unit is connected to from the rubbing crusher of smashing the rim charge the conveying pipe of main hopper and be used for the propelling movement to smash the pay-off fan that the material was carried along the conveying pipe.
Specifically, the rim charge is fed into the pulverizer through a reversing roller.
Specifically, the outlet of the feeding pipe is provided with a feeding barrel, the feeding barrel is provided with an outlet positioned at the bottom, and the outlet faces the main hopper.
Compared with the prior art, the utility model discloses technical scheme's beneficial effect is:
this device can send back the raw materials in the middle of cutting the direct breakage of rim charge that produces, has avoided the trouble of artifical recovery, retrieves the circulation and need not shut down, has reduced the pollution risk, has promoted work efficiency.
Drawings
Fig. 1 is a schematic structural view of an edge-trim reflow apparatus according to an embodiment.
Labeled as:
11-a main hopper, 12-a spiral feeder, 13-an extrusion head and 14-a transition head;
21-extrusion roller, 22-tension roller, 23-cutting knife, 24-winding roller and 25-reversing roller;
31-a pulverizer, 32-a feeding fan, 33-a feeding pipe and 34-a feeding barrel;
41-extruding a sheet material, 42-finished material belt and 43-leftover material.
Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1, the utility model discloses an rim charge reflux unit for extruder for having a main hopper 11, a screw feeder 12, one extrude first 13, three extrusion roller 21, a plurality of tension roller 22 and a wind-up roll 24, be equipped with between the tension roller 22 and be used for extruding sheet 41 and cut into finished product material area 42 and rim charge 43's cutting sword 23, rim charge reflux unit is including the rubbing crusher 31 that is used for smashing rim charge 43, be connected to the conveying pipe 33 of main hopper 11 from rubbing crusher 31 and be used for propelling movement rubbing crusher along the feeding fan 32 that conveying pipe 33 carried. The raw material is fed from the main hopper 11, and then melted in the screw feeder 12 and sent to the extrusion head 13 to be extruded into a strip-shaped extruded sheet 41, the extruded sheet 41 is cooled and shaped into a required thickness by the extrusion roller 21, then the extruded sheet 41 is tightened under the action of the tension roller 22, at this time, the edge material 43 is cut off by the cutting knife 23, and the finished material belt 42 can be wound into a roll at the winding roller 24 and discharged. After the scrap 43 is produced, the scrap 43 is directly sent to the crusher 31 to be crushed into small pieces convenient for wind power conveying, so that the crushed material can be blown to the main hopper 11 by the feeding fan 32 to be re-melted after being mixed with the raw material, the circulation of the scrap 43 is completed, the trouble of manual recovery is avoided, and the recovery circulation is not required to be stopped. Because nobody contacts the recovered materials, the pollution risk is reduced, and the working efficiency is improved.
As shown in fig. 1, the scrap 43 is fed into the crusher 31 through a reverse roll 25. The crusher 31 will roll the edge strip 43 into it, and the reversing roller 25 can prevent the edge strip 43 from being pulled to affect the normal conveying of the finished strip 42.
As shown in FIG. 1, the outlet of the feeding pipe 33 is provided with a feeding barrel 34, and the feeding barrel 34 has an outlet (not labeled) at the bottom, which is directed toward the main hopper 11. The crushed material entering the feeding barrel 34 falls to the outlet and then falls to the main hopper 11, and the wind force is released from other positions, so that the wind force of the feeding fan 32 cannot blow to the main hopper 11 to blow the material and then cause air to enter the spiral feeder 12 to cause material breakage.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
