Description

Technical Field

[0001] The utility model patent relates to the field of cigarette processing and shredding equipment, and specifically to a right-side scraper for a shredder. Background Art

[0002] KT3 shredder is a process equipment on the tobacco industry's silk production line. Its function and task is to cut tobacco leaves or stems with certain temperature and humidity conditions into shredded tobacco or shredded stems with a width that meets the process requirements. During the production process, the rotation axis of the knife roller is perpendicular to the material conveying direction, and the rotation trajectory of the blade edge is a cylindrical surface. The rotating knife roller drives the blade to cut the material continuously in sequence. The cut tobacco and scraps will be thrown out along the tangent direction of the knife roller under the action of centrifugal force. A slide plate is provided in the opposite direction of the knife roller to block the tobacco thrown out during shredding. After long-term operation, tobacco scale will be generated on the slide plate. In order to scrape off the tobacco scale on the slide plate, the shredder is provided with scrapers on the left and right sides of the knife roller body. The horizontal reciprocating motion of the grinding wheel drives the slide plate to move left and right to scrape off the tobacco scale on the slide plate.

[0003] The existing right scraper is in the shape of a rectangular sheet, and the scraper base is installed on the base of the knife roller body. The pressure strip installs the sheet-shaped rectangular blade on the scraper base. The blade has low strength and is easy to wear and deform. After the scraper is worn and deformed, there is a gap between it and the slide plate, which makes it impossible to scrape off the soot on the slide plate, and the slide plate is seriously scaled. After the scraper scrapes off the soot on the slide plate, the soot cannot be discharged in time, and the soot accumulates on the scraper, which aggravates the wear of the scraper and the slide plate, increases the resistance of the grinding wheel during reciprocating motion, and causes the grinding wheel reciprocating device to be stuck or the transmission system to shut down due to failure. Summary of the invention

[0004] The invention purpose of this utility model patent is to provide a right-side scraper for a wire cutting machine. It changes the structure and installation method of the original scraper. The improved right-side scraper is not only simple in structure and easy to install, but also increases the strength of the scraper, ensuring that the right-side scraper can promptly and effectively scrape off the soot on the grinding wheel slide during the operation of the wire cutting machine.

[0005] In order to achieve the invention purpose of the utility model, the utility model adopts the following technical solutions:

[0006] The utility model discloses a right-side scraper for a shredder, comprising: a scraper and a scraper body, wherein: the scraper body is a rectangular plate, at least three mounting holes are opened on the rectangular plate, screws are installed on the mounting holes, and the scraper body is fixed on the blade roller body base of the shredder, the scraper is located on the long side of one side of the rectangular plate, the scraper is composed of a first blade edge, a second blade edge and a third blade edge connected in sequence, an angle a between the first blade edge and the upper short side of the rectangular plate is 130° to 140°, the second blade edge is parallel to the upper short side of the rectangular plate, and an angle b between the third blade edge and the lower short side of the rectangular plate is 95° to 105°.

[0007] The utility model discloses a right-side scraper for a shredder, wherein the scraper and the scraper body are integrated.

[0008] The utility model provides a right-side scraper for a shredder, wherein: the first blade edge and the upper short side of the rectangular plate are connected to form an arc transition.

[0009] The utility model discloses a right-side scraper for a shredder, wherein: there are four mounting holes, which are countersunk holes.

[0010] Compared with the prior art, the right scraper for the shredder of the utility model has the following beneficial effects:

[0011] 1. The improved scraper is an integrated type. Compared with the prior art in which the scraper base is installed on the blade roller body base, the pressure strip installs the sheet-shaped rectangular blade on the scraper base, which has a simple structure and is easy to install.

[0012] 2. The blade edge of the improved scraper is in the shape of a triangular prism, which is stronger, more durable and has a longer service life than the sheet-shaped rectangular blades in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] See also Figure 1-2As shown, the utility model is a right-side scraper for a wire cutting machine, comprising: a scraper 1 and a scraper body 2, the scraper 1 and the scraper body 2 are integrated, the scraper body 2 is a rectangular plate, and four mounting holes 3 are opened on the rectangular plate, which are countersunk holes, screws are installed in the above mounting holes 3, and the scraper body 2 is fixed on the blade roller body base of the wire cutting machine, the scraper 1 is located on the long side of one side of the rectangular plate, the scraper 1 is composed of a first blade edge 4, a second blade edge 5 and a third blade edge 6 connected in sequence, the angle a between the first blade edge 4 and the upper short side of the rectangular plate is 130° to 140°, the first blade edge 4 and the upper short side of the rectangular plate are connected as a circular arc transition, the second blade edge 5 is parallel to the upper short side of the rectangular plate, and the angle b between the third blade edge 6 and the lower short side of the rectangular plate is 95° to 105°.

[0018] like Figure 3 As shown, the working principle is: the right scraper 7 is directly installed on the KT3 wire cutter blade roller body base 8 by screws. After installation, the first blade edge 4, the second blade edge 5 and the third blade edge 6 are parallel to the KT3 wire cutter grinding wheel slide slide. When the KT3 wire cutter is working, the grinding wheel moves back and forth horizontally to drive the slide to move left and right, and the scraper 1 scrapes off the soot on the slide.

[0019] The above is only a specific implementation method of the utility model patent, but the protection scope of the utility model patent is not limited to this.
