Description

Technical Field

[0001] The utility model relates to a debris removal structure, in particular to a debris removal structure used on a sawtooth lint stripping machine. Background Art

[0002] Sawtooth delinting machine is a device used to remove short lint from cotton seeds. It is widely used in cotton processing enterprises due to its advantages of high degree of automation, good delinting quality and high delinting efficiency.

[0003] A sawtooth linting machine generally includes a frame, a saw blade drum rotatably mounted on the frame, and a debris removal structure fixed to the frame and located below the saw blade drum. The debris removal structure includes an air suction nozzle and an impurity removal knife fixed to the air suction nozzle. The distance between the air suction nozzle and the saw blade drum, and the distance between the impurity removal knife and the saw blade drum, need to meet actual usage requirements to ensure the impurity removal effect. During the operation of the sawtooth linting machine, when cotton seeds pass through the saw blade drum, the high-speed rotating saw blade drum contacts the lint on the surface of the cotton seeds and uses the cutting and pulling action of the saw blade to separate the lint from the cotton seeds. At this time, impurities such as cottonseed shell fragments, dust, and cotton leaves will also be attached to the lint. When these impurities pass through the impurity removal structure, the impurity removal knife can scrape off the impurities attached to the lint, and the air suction nozzle sucks out the scraped impurities, after which relatively pure lint can be obtained.

[0004] After long-term use, the saw blades in the saw drum of existing sawtooth depilers often become blunt. These blunt saw drums are typically re-chiselled using a chisel machine before being re-installed in the sawtooth depiler. However, the size of the saw drum becomes smaller after this process, and the position of the existing suction nozzle and debris removal blade cannot be adjusted. Consequently, the distance between the suction nozzle and the saw drum, as well as the distance between the debris removal blade and the saw drum, becomes larger than before, seriously affecting the depilation efficiency of the sawtooth depiler. Summary of the Invention

[0005] In order to solve the above deficiencies in the prior art, the utility model aims to provide a debris removal structure applied to a sawtooth lint stripping machine, so as to achieve the purpose of improving the debris removal effect of the sawtooth lint stripping machine.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a debris removal structure applied to a sawtooth stripping machine, comprising a mounting hole assembly provided on a frame of the sawtooth stripping machine, a suction nozzle assembly provided on the mounting hole assembly and located below and behind the saw blade drum of the sawtooth stripping machine, and a debris removal knife assembly provided on the mounting hole assembly and located above the suction nozzle assembly, the suction nozzle assembly being positionably connected to the mounting hole assembly to adjust the distance between the suction nozzle assembly and the saw blade drum, and the debris removal knife assembly being positionably connected to the mounting hole assembly to adjust the distance between the suction nozzle assembly and the saw blade drum.

[0007] As a limitation of the present invention, the mounting hole assembly includes two groups of suction nozzle front end mounting holes arranged on both sides of the frame for connecting to the front end of the suction nozzle assembly, two groups of suction nozzle rear end mounting holes arranged on both sides of the frame for connecting to the rear end of the suction nozzle assembly, and two groups of debris removal knife mounting holes arranged on both sides of the frame for connecting to the debris removal knife assembly.

[0008] As a further limitation of the present invention, the suction nozzle assembly includes two suction nozzle front end mounting seats, two suction nozzle rear end mounting seats and an air suction nozzle, wherein the two suction nozzle front end mounting seats can be respectively positioned and movably connected to two groups of suction nozzle front end mounting holes, the two suction nozzle rear end mounting seats can respectively be positioned and movably connected to two groups of suction nozzle rear end mounting holes, the two sides of the front end of the suction nozzle are respectively fixed on the two suction nozzle front end mounting seats, and the two sides of the rear end of the suction nozzle are respectively fixed on the two suction nozzle rear end mounting seats.

[0009] As a further limitation of the present invention, the debris removal knife assembly includes two debris removal knife mounting seats, a mounting shaft and a debris removal knife, wherein the two debris removal knife mounting seats can be movably connected to the two groups of debris removal knife mounting holes, and the two ends of the mounting shaft are respectively fixed on the two debris removal knife mounting seats, and the two ends of the debris removal knife are each fixed on the mounting shaft through a connecting plate.

[0010] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0011] (1) The utility model adopts a structural form that combines a mounting hole assembly, an air suction nozzle assembly, and a debris removal knife assembly, wherein the air suction nozzle assembly is movably connected to the mounting hole assembly and can adjust the distance between the air suction nozzle assembly and the saw blade drum, and the debris removal knife assembly is movably connected to the mounting hole assembly and can adjust the distance between the debris removal knife assembly and the saw blade drum. When the size of the saw blade drum after processing becomes smaller, the distance between the air suction nozzle assembly and the saw blade drum and the distance between the debris removal knife assembly and the saw blade drum can be adjusted to appropriate sizes respectively, which can effectively improve the debris removal effect of the sawtooth depilator.

[0012] (2) In the present invention, the two front-end mounting seats can be positioned and movably connected to the two front-end mounting holes of the suction nozzles, and the two rear-end mounting seats can be positioned and movably connected to the two rear-end mounting holes. The two sides of the front end of the suction nozzle can be stably fixedly connected to the two front-end mounting seats of the suction nozzles, and the two sides of the rear end of the suction nozzle can be stably fixedly connected to the two rear-end mounting seats of the suction nozzles, thereby ensuring that the overall structure of the suction nozzle is stably fixed on the frame.

This allows the air suction nozzle assembly and the debris removal knife assembly to be in appropriate positions during debris removal work, effectively improving the debris removal effect of the sawtooth depilator. The present invention is suitable for installation on a sawtooth depilator. BRIEF DESCRIPTION OF THE DRAWINGS
