Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of continuous extrusion, in particular to a split scraper of a continuous extruder. Background Art
[0002] The continuous extrusion process involves the rod material, compacted against the extrusion wheel groove, being continuously fed by friction as the wheel rotates. It encounters a block, causing it to change direction and extrude the product through the die. This production process inevitably leaves residual rod material adhering irregularly to the bottom and sides of the wheel groove with each compaction and feeding. To ensure proper process operation, this residual rod material must be cleaned from the wheel groove. An existing solution involves using an integrated scraper to clean the entire extrusion wheel and groove.
[0003] However, the existing technology has the following difficulties: 1. The gap between the scraper and the wheel groove is difficult to control. In the past, it mainly relied on the workers' experience, or the gap was adjusted by pressing lead wire before each production, which was a cumbersome process; 2. The degree of wear of the scraper's cutting edge in contact with the extrusion wheel and the extrusion wheel groove was inconsistent. Often, the scraper needs to be replaced because the cutting edge of the wheel groove reaches its service limit first, resulting in unnecessary waste; 3. The scraper needs to be replaced as a whole for different wheel groove structures, and its adaptability is poor. Utility Model Content
[0004] The purpose of the present invention is to solve the problems of the above-mentioned background technology and to provide a split scraper for a continuous extruder.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] A split scraper for a continuous extruder includes an extrusion wheel scraper base, a slide groove is provided at the front end of the extrusion wheel scraper base, a wheel groove scraper slides in the slide groove, a through threaded hole is provided at the tail end of the extrusion wheel scraper base, the threaded hole is connected to the slide groove, a rod body is inserted into the threaded hole, one end of the rod body is connected to the wheel groove scraper, the rod body is threadedly connected to the threaded hole, and the rod body is used to push the wheel groove scraper to move back and forth in the slide groove.
[0007] As a further solution of the present invention: a fixing sleeve is slidably provided in the slide groove at the tail end of the wheel groove scraper, the fixing sleeve is sleeved on the rod body, and the end of the fixing sleeve is clamped with the wheel groove scraper.
[0008] As a further solution of the present invention: a connecting ring is further provided at the end of the rod body, and the connecting ring is embedded between the fixing sleeve and the wheel groove scraper.
[0009] As a further solution of the present invention: a notch is provided on the top of the extrusion wheel scraper base body near the fixed sleeve, and scale marks for reading are provided on the notch and the fixed sleeve.

[0012] As a further solution of the present invention: the extrusion wheel scraper base is in the shape of a flat plate.
[0013] As a further solution of the present invention: a cutting edge is formed at the front end of the wheel groove scraper.
[0014] The beneficial effects of the utility model are as follows: the scraper is split into a flat extrusion wheel scraper base and a movable wheel groove scraper, and scale markings are added to the scraper. When in use, the scraper base can be fixed on the extruder first, and then the rocker can be adjusted to make the wheel groove scraper contact with the extrusion wheel groove and then retreat to the required gap. The wheel groove scraper can be replaced according to different wheel groove structures. BRIEF DESCRIPTION OF THE DRAWINGS
