The carding cutter mainly consists of a swing cutter arm and cutter blades. The carding cutter is needed when the carding machine is carding the cotton material.

[0003] The existing technology has the following problems:

[0004] Traditionally, the blade and arm of a chopping knife are fixed together by welding multiple metal rods. This makes it inconvenient to replace the blade and adjust the distance between the blade and the arm. In addition, traditional blades are not easy to protect during operation, and the bottom of the blade is easily bent and deformed by impact. Utility Model Content

[0005] The purpose of this invention is to provide a carding machine cutter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carding machine cutter, comprising a cutter arm and a cutter blade movably connected to one side of the cutter arm. The cutter arm is provided with a connecting assembly and a protective assembly. The connecting assembly includes two fixed cylinders fixedly installed on one side of the cutter arm. Rotary cylinders are rotatably installed on the outer sides of the two fixed cylinders. Two fixed rods are fixedly installed on one side of the cutter blade, and the two fixed rods extend to the inner sides of the two fixed cylinders respectively. Fixed rings are fixedly installed on one side of the two rotating cylinders, and the two fixed rings are located at one end of the two fixed cylinders and outside the two fixed rods respectively. Fixed knobs are threadedly connected to the top of the two rotating cylinders. The protective assembly includes a protective sleeve fixedly installed on the bottom of the cutter blade. A protective groove is opened on the inner side of the protective sleeve, and the bottom of the cutter blade extends into the protective groove.

[0007] By rotating the drum and simultaneously rotating the fixing ring, the fixing rod can be easily moved left and right along the fixing drum. By moving the fixing rod to the left and separating it from the fixing drum, the cutting blade can be easily replaced. By extending the fixing rod to a suitable position inside the fixing drum, the distance between the cutting blade and the cutting arm can be adjusted. By rotating the fixing knob, the drum and the fixing drum can be fixed together, and the fixing ring can be fixed simultaneously. The fixing ring can be used to fix the fixing rod and the fixing drum. By putting the protective sleeve on the bottom of the cutting blade and inserting the bottom of the cutting blade into the protective groove, the cutting blade can be easily protected and prevented from bending or deforming due to impact. By installing and fixing the cutting arm on the carding machine, the cutting blade can completely peel off the wool layer picked up by the doffer from the cylinder to form a wool web.

[0008] Preferably, a sponge pad is fixedly installed on the inner side of the protective groove, and multiple fixing blocks are fixedly connected to both sides of the inner wall of the protective groove, with the fixing blocks corresponding to the cutting blade.

[0010] Preferably, both fixing rings have internal threads on their inner sides, and both fixing rods have threaded grooves on their outer peripheries. The two threaded grooves respectively engage with the two internal threads. By rotating the fixing rings, the internal threads are simultaneously rotated. Utilizing the engagement of the threaded grooves with the internal threads, the rotation of the fixing rings causes the fixing rods to move left and right, simultaneously causing the cutting blade to move left and right.

[0011] Preferably, each of the two rotating cylinders has a threaded sleeve on its inner side, which engages with two fixing knobs respectively. Each of the two fixing cylinders has multiple fixing grooves on its outer periphery, which correspond to the fixing knobs. By engaging the threaded sleeves with the fixing knobs, the fixing knobs can move up and down during rotation. By extending the bottom of the fixing knobs into the fixing grooves, the rotating cylinders and fixing cylinders can be secured.

[0012] Preferably, support rings are fixedly installed on the periphery of both fixed cylinders, with each support ring located on one side of a fixed knob. Sliding grooves are formed on the inner walls of both rotating cylinders, and the support rings extend into and are rotatably installed within these grooves. When the rotating cylinders rotate, the support rings can slide along the sliding grooves, preventing the cylinders from moving left or right during rotation.

[0013] This invention provides a carding machine cutter. Compared with the prior art, it has the following advantages: By setting up a fixed cylinder, a rotating cylinder, a fixed ring, a fixed rod, and a protective sleeve, the rotating cylinder rotates, simultaneously driving the fixed ring to rotate, which facilitates the left and right movement of the fixed rod along the fixed cylinder.
