Technical Field

[0001] The utility model relates to the technical field of non-woven fabric cutting, in particular to a non-woven fabric multi-layer cross-cutting machine with convenient replacement of cutting blades. Background Art

[0002] Non-woven fabric, also known as non-woven fabric or non-woven fabric, is a kind of fabric that does not require weaving. It is not made through traditional spinning and weaving processes, but is formed by directly bonding the fibers together by physical methods. The production process of non-woven fabrics includes airflow or mechanical web formation of fibers, followed by reinforcement by hydroentanglement, needle punching or hot rolling, and finally finishing to form a non-woven fabric. This kind of fabric is moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, low in price, and recyclable. The material of non-woven fabrics can be chemical fiber or plant fiber. According to different uses and needs, non-woven fabrics can be applied to multiple fields, such as agriculture, medical and health care, clothing, home decoration, etc.;

[0003] In the production and processing of non-woven fabrics, non-woven fabric cross-cutting machines are used. Non-woven fabric cross-cutting machines are instruments used to cut non-woven fabrics horizontally.

[0004] When replacing the cutter of a conventional non-woven multi-layer cross-cutting machine, the operator usually manually disassembles and assembles the structure. However, due to the structure, size, weight and other factors of the cutter itself, the disassembly and assembly process is relatively time-consuming and labor-intensive. At the same time, safety accidents are prone to occur, causing harm to the operator and damage to the cutting edge of the cutter itself.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a non-woven multi-layer cross-cutting machine with easy replacement of cutting knives is proposed. Utility Model Content

[0006] The utility model aims to provide a non-woven fabric multi-layer cross-cutting machine with easy replacement of cutting blades, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a non-woven multi-layer cross-cutting machine that is easy to replace the cutting knife, comprising a cross-cutting knife group and an auxiliary bracket, an auxiliary bracket is arranged directly below the cross-cutting knife group, and the left and right sides of the cross-cutting knife group are connected to adjustment brackets, and the side of the adjustment bracket away from the cross-cutting knife group is connected to a traction bracket, the auxiliary bracket comprises a knife holder, a supporting bracket, a lead screw, a servo motor and a guide frame, supporting brackets are installed on both sides of the bottom of the knife holder, and the supporting bracket on one side of the knife holder is penetrated by a lead screw, and the bottom end of the lead screw is installed with a servo motor through a coupling, and one side of the supporting bracket on the other side of the knife holder is vertically penetrated by a guide frame.

[0008] Furthermore, the cross-cutting knife group includes a fixing frame, an adjusting pile, a cutter body and a fixing bolt. The adjusting piles are installed on the left and right ends of the fixing frame, and the cutter body is installed on the bottom of the fixing frame. Moreover, a fixing bolt runs horizontally through the left and right ends of the cutter body and the fixing frame.

[0009] Furthermore, the adjusting pile is connected to the fixing frame by welding, and the cutter body is inserted into the inner side of the bottom of the fixing frame, and the fixing bolts are respectively connected to the fixing frame and the cutter body by threading.

[0010] Furthermore, the support bracket on one side of the bottom of the tool holder is threadedly connected to the lead screw, and the support bracket on the other side of the bottom of the tool holder is slidably connected to the guide frame.

[0011] Furthermore, the adjustment frame includes a stabilizing frame, a guide slider, a driving motor and a screw rod. A guide slider is installed on one side of the stabilizing frame, and a driving motor is installed on the upper end of the stabilizing frame away from the guide slider, and a screw rod is installed on the bottom power output end of the driving motor through a coupling.

[0012] Furthermore, one side of the adjusting pile is slidably connected to the stabilizing frame, and the middle part of the adjusting pile is threadedly connected to the screw rod.
