The cutting action is completed well, and the labor cost is reduced. The entire device is ingeniously designed and has excellent performance.

[0004] However, when existing cutting mechanisms cut copper wires, the copper wires tend to move, which affects the cutting effect. Therefore, there is an urgent need in the market for a cutting mechanism for a sleeve winding machine to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting mechanism for a sleeve winding machine to solve the problem mentioned in the background art that the copper wire moves when cutting the copper wire, thus affecting the cutting effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A cutting mechanism for a tubing winding machine includes a cutting device frame, a cylinder mounted on top of the cutting device frame, a push rod at the lower end of the cylinder, a connecting seat at the lower end of the push rod, a fixed seat mounted below the connecting seat, an mounting seat at the lower end of the fixed seat, a cutting blade mounted below the mounting seat, a cutting device seat mounted inside the upper part of the cutting device frame, wire inlets at both ends of the cutting device seat, a cutting groove at the lower end of the interior of the cutting device seat, limit grooves on the interior of both opposite inner walls of the cutting device seat, and compression cylinders mounted on both sides above the cutting device seat, telescopic rods at the lower ends of the compression cylinders, and compression seats mounted below the telescopic rods.

[0007] Preferably, the connecting seat and the fixed seat are fixedly connected by a fixing screw, one end of which passes through the connecting seat and extends into the interior of the fixed seat.

[0008] Preferably, a limiting slide rail is installed on one side of the inner wall of the cutting device frame, and a limiting end corresponding to the limiting slide rail is provided at one end of the connecting seat.

[0009] Preferably, the upper end of the cutting blade is provided with a connecting end, and the connecting end is fixedly connected to the mounting base by connecting screws, and the cutting blade is provided with a corresponding cutting groove.

The limiting slide block is provided in correspondence with the limiting slide groove, and the limiting slide block is located inside the limiting slide groove.

[0011] Preferably, there are two extrusion cylinders, which are symmetrical about the vertical center line of the cutting device seat. Each end of the outer wall of the extrusion cylinder is provided with a mounting foot, which is fixedly connected to the cutting device seat by mounting screws.

[0012] Preferably, the upper end of the compression seat is provided with a fixed end, one end of the telescopic rod is located inside the fixed end, and the telescopic rod and the fixed end are fixedly connected by hexagonal screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) When the present invention is working, when the sleeve winding machine needs to cut the wire during early winding, the extrusion cylinder is opened to make the telescopic rod push the extrusion seat to move. The extrusion seat can squeeze and fix the copper wire. Then, the cylinder is opened to make the push rod push the connecting seat to move. The connecting seat makes the mounting seat push the cutting knife to move. The cutting knife can easily and quickly cut the copper wire. In this way, the copper wire is prevented from moving during cutting, which would affect the working effect of the sleeve winding machine.

[0014] (2) The present invention enables the limiting end to move along the direction of the limiting slide rail by the corresponding limiting slide rail and limiting end, which can prevent the cutting knife from deviating and thus affecting the cutting effect of copper wire. The corresponding limiting slide and limiting slide groove can further prevent the cutting knife from deviating and thus affecting the cutting effect of copper wire. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1-4This utility model provides an embodiment of a cutting mechanism for a tubing winding machine, comprising a cutting device frame 1, a cylinder 2 mounted above the cutting device frame 1, a push rod 201 at the lower end of the cylinder 2, a connecting seat 3 at the lower end of the push rod 201, a fixing seat 4 mounted below the connecting seat 3, and the connecting seat 3 and the fixing seat 4 being fixedly connected by a fixing screw 5, one end of the fixing screw 5 passing through the connecting seat 3 and extending into the interior of the fixing seat 4, a mounting seat 7 at the lower end of the fixing seat 4, a cutting blade 9 mounted below the mounting seat 7, and a cutting blade 9 mounted above the interior of the cutting device frame 1. The cutting device base 8 has wire inlets 801 at both ends, a cutting groove 802 at the lower end of the interior of the cutting device base 8, and limit grooves 803 on the inner walls of the two opposite sides of the cutting device base 8. Extrusion cylinders 11 are installed on both sides of the upper part of the cutting device base 8, and telescopic rods 1101 are installed at the lower end of the extrusion cylinders 11. Extrusion seats 12 are installed below the telescopic rods 1101. It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the working principle and process of cutting copper wire, it will not be described in detail in this patent.

[0019] See Figure 1 and Figure 3 A limiting slide rail 6 is installed on one side of the inner wall of the cutting device frame 1. One end of the connecting seat 3 is provided with a limiting end 301 corresponding to the limiting slide rail 6. This setting allows the limiting end 301 to move along the direction of the limiting slide rail 6, thus preventing the mounting seat 7 from deviating when it drives the cutting knife 9 to move, which would affect the efficiency of the cutting knife 9 in cutting copper wire.

[0020] See Figure 1 , Figure 2 and Figure 4 The upper end of the cutting blade 9 is provided with a connecting end 901, which is fixedly connected to the mounting base 7 by a connecting screw 10. The cutting blade 9 is correspondingly provided with the cutting groove 802. One end of the mounting base 7 is located inside the cutting device base 8. Each of the two opposite outer walls of the mounting base 7 is provided with a limiting slide 701, which is correspondingly provided with a limiting slide groove 803. The limiting slide 701 is located inside the limiting slide groove 803. The connecting screw 10 can be used to easily install and fix the connecting end 901 and the mounting base 7. The corresponding cutting blade 9 and cutting groove 802 can easily cut the copper wire. The corresponding limiting slide 701 and limiting slide groove 803 can limit the movement of the mounting base 7 along the direction of the limiting slide groove 803, preventing the mounting base 7 from shifting and affecting the cutting effect.

[0021] See Figure 1 , Figure 2 and Figure 3Two extrusion cylinders 11 are provided, symmetrical about the vertical center line of the cutting device seat 8. Each end of the outer wall of the extrusion cylinder 11 has a mounting foot 1102, which is fixedly connected to the cutting device seat 8 by mounting screws 1103. The upper end of the extrusion seat 12 has a fixed end 1201, with one end of the telescopic rod 1101 located inside the fixed end 1201. The telescopic rod 1101 and the fixed end 1201 are fixedly connected by hexagonal screws 13. The mounting screws 1103 facilitate the installation and fixation of the extrusion cylinder 11 and the cutting device seat 8, and the hexagonal screws 13 facilitate the installation and fixation of the telescopic rod 1101 and the fixed end 1201. The extrusion cylinders 11 enable the telescopic rod 1101 to push the extrusion seat 12 to move, and the extrusion seat 12 can extrude and fix the wire, preventing the copper wire from shifting during cutting, thus affecting the cutting effect and the operation of the sleeve winding machine.

[0022] Working principle: In use, the copper wire passes through the inlet 801 and extends to the outside of the cutting device seat 8. When the tubing winding machine needs to cut the wire during winding, the extrusion cylinder 11 is opened to move the telescopic rod 1101 to push the extrusion seat 12. The extrusion seat 12 can extrude and fix the copper wire. Then, the cylinder 2 is opened to move the push rod 201 to push the connecting seat 3. The connecting seat 3 causes the mounting seat 7 to push the cutting knife 9 to move. The cutting knife 9 can cut the copper wire conveniently and quickly. This avoids the copper wire from moving during cutting, which would affect the working effect of the tubing winding machine.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
