Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, and specifically relates to a wire cutting device of a wire drawing machine. Background Technique

[0002] Plastic wire drawing machines mainly use polypropylene and high-density ethylene as raw materials. Through heating, extrusion, wire cutting, and stretching, flat wires are formed and finally wound by a circular loom to be woven into bags. The wire drawing width in existing plastic wire drawing machines is generally determined according to the cutting knife. Once the cutting knife model is set, the wire drawing width is also determined. Moreover, the existing cutting knife has a fixed structure. During the wire cutting process, the cutting knife is easily damaged and has a short service life.

[0003] For example, a wire cutting device of a wire drawing machine that is easy to replace the cutting knife disclosed in the authorized announcement number CN205889355U. This wire cutting device of the wire drawing machine includes a main seat and a cutting knife. The characteristics are as follows: an installation groove is provided on the main seat, a tool holder is matched in the installation groove, a long strip-shaped groove is provided on the tool holder, and the cutting knife is installed in the long strip-shaped groove. According to the wire cutting device of the wire drawing machine provided by the utility model, since the cutting knife is installed on the main seat through the tool holder, during replacement, only the tool holder and the cutting knife need to be replaced together. Since the tool holder and the cutting knife are light in weight, the replacement is very convenient. However, this wire cutting device lacks a convenient blade lifting measure. After the cutting edge is worn, only a new blade can be replaced, which is not only time-consuming and laborious, but also wasteful, and is not convenient for ensuring the economic benefits and working efficiency of the device. Therefore, we have proposed a wire cutting device of a wire drawing machine, which solves the blade lifting problem of the device and improves the use convenience and economic benefits of the device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wire cutting device of a wire drawing machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A wire cutting device for a wire drawing machine, comprising a wire cutting mechanism, an adjusting mechanism and an auxiliary fixing mechanism. The adjusting mechanism is located at the bottom end of the wire cutting mechanism, and the auxiliary fixing mechanism is located outside the wire cutting mechanism. The wire cutting mechanism includes a cutter roller, an installation groove, a blade box, a clamping block, a blade, a fixing hole and a fixing screw. The cutter roller is provided with an installation groove, the blade box is movably installed inside the installation groove, the blade is fixedly installed between the clamping blocks, the clamping block and the blade box are correspondingly provided with fixing holes with the same diameter, and the fixing screw passes through the fixing hole and is threadedly connected. The adjusting mechanism includes an adjusting bolt, a rotating handle, a bearing and a wedge-shaped extrusion block. One end of the adjusting bolt is fixedly provided with a rotating handle, the other end thereof passes through the outer wall of the installation groove and is threadedly connected, the other end of the adjusting bolt is rotatably connected with a bearing, and one side of the bearing is fixedly connected with a wedge-shaped extrusion block.

[0007] Preferably, the auxiliary fixing mechanism includes a limiting chute, a limiting slider, a clamping and fixing groove, a clamping bolt and a rubber end head. The limiting chute is opened on both sides of the blade box.

[0008] Preferably, the limiting slider is arranged on the inner wall of the installation groove and corresponds to the limiting chute one by one.

[0009] Preferably, the clamping and fixing groove is opened at both ends of the blade box, and one end of the clamping bolt passes through the outer wall of the installation groove and is threadedly connected.

[0010] Preferably, one end of the clamping bolt is provided with a rubber end head.

[0011] Preferably, the diameter of the rubber end head is slightly smaller than the width of the clamping and fixing groove.

[0012] Preferably, the horizontal central axis of the clamping bolt is perpendicular to the vertical central line of the clamping and fixing groove and is located in the same plane.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. For this wire cutting device of the wire drawing machine, through the cutter roller, installation groove, blade box, clamping block, blade, fixing hole and fixing screw provided by the wire cutting mechanism, the clamping block equipped with the blade is installed in the blade box, and then the blade box and the clamping block are fixedly connected through the fixing screw and the fixing hole. Finally, through the limiting chute arranged on both sides of the blade box and the limiting slider arranged on the inner wall of the installation groove, the blade box is slidably installed inside the installation groove. This installation method is relatively convenient, facilitating the installation, disassembly and maintenance operations of the blade in the later stage, and improving the use convenience of the device.

[0015] 2. The wire cutting device of this wire drawing machine drives the adjusting bolt to rotate by turning the rotating handle set by the rotation adjusting mechanism, thereby driving the wedge-shaped extrusion block to extrude forward. Since the wedge-shaped extrusion block is designed with an inclined surface, during the extrusion process, it can push the blade box to move upward along the limit sliding groove. When the blade is worn out after being used for a long time, this adjustment method can quickly improve the working surface of the blade edge, reduce the number of tool replacements, make the blade fully utilized, and avoid waste. Through the limit sliding groove, limit slider, clamping fixing groove, clamping bolt and rubber end set by the auxiliary fixing mechanism, the clamping fixation and limiting effects of the device during installation, maintenance and use are achieved, and the use stability of the device is improved.
