Description

Technical Field

[0001] The utility model relates to the field of wire tying machines, and particularly relates to a wire tying machine with a cutting function. Background Art

[0002] A wire tying machine, also known as a wire sealing machine, is a commonly used wire processing device. It mainly rotates the wire or cable by using a rotating workbench and seals the wire or cable through mechanisms such as a spiral spring, making it more neat and beautiful. At the same time, it enhances the stability and service life of the wire. On the wire production line, the wire tying machine can automatically complete the bundling work of the wire, which not only reduces manual operation, lowers the labor intensity, but also ensures the consistency and stability of bundling, improving the production efficiency and product quality. Therefore, the wire tying machine plays an indispensable role in wire production.

[0003] In the prior art, during the production of wires, when the wire reaches a preset length through the length measuring wheel, it will be cut off by a cutting mechanism. After cutting, the wire of a specific length will be wound and tied by the wire tying machine. However, in the actual use of the cutting mechanism on the existing wire tying machine, during the long-term use of the cutting knife, due to the direct contact and friction with the wire, it will gradually wear. This wear will cause the sharpness of the cutting edge to decline. As the cutting edge wears, problems such as unevenness and burrs may appear at the cut end of the wire, thus affecting subsequent processing and use as well as the cutting accuracy and efficiency. Therefore, the cutting knife needs to be replaced. However, most of the existing cutting knives are fixed on the cutting knife seat by multiple bolts, resulting in troublesome operation when disassembling and installing the cutting knife. It is necessary to use auxiliary tools to disassemble, install, and tighten the bolts in sequence, which not only brings inconvenience to the disassembly and installation operation of the cutting knife on the cutting mechanism, but also consumes a long time to replace the cutting knife, which will affect the production and processing efficiency of the wire. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a wire tying machine with a cutting function, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A wire tying machine with a cutting function, comprising a wire tying machine body and a cutting mechanism arranged on the wire tying machine body. The cutting mechanism includes a concave support frame, a cylinder, a mounting knife holder, a fixing rod, a compression spring, a movable plate, a limiting rod and a cutting knife. The concave support frame is fixedly connected to the machine table of the wire tying machine body, and a set of symmetric cylinders are fixedly connected to the top surface of the concave support frame. The output end of the cylinder is fixedly connected with a mounting knife holder, and the mounting knife holder is movably connected with the concave support frame through a T-shaped sliding block on the bottom surface.

Symmetric limiting rods are fixedly connected to the inner side wall of the movable plate, and the movable plate fixedly connects the cutting knife to the mounting opening formed in the mounting knife holder through the limiting rods.

[0007] Preferably, an inverted concave support frame is fixedly connected to the machine table of the wire tying machine body, and a T-shaped sliding groove is formed on the top surface of the concave support frame.

[0008] Preferably, a set of symmetric cylinders are also fixedly installed on the top surface of the concave support frame, and a mounting knife holder is fixedly installed on the output end of the cylinder. A T-shaped sliding block is fixedly installed on the bottom surface of the mounting knife holder, and the T-shaped sliding block is movably installed in the T-shaped sliding groove.

[0009] Preferably, a mounting opening is formed on the inner side wall of the mounting knife holder, and an inner cavity is formed inside the mounting knife holder. A set of symmetric side holes are respectively formed on both side walls of the mounting opening, and the side holes communicate with the inner cavity. A set of through holes communicating with the inner cavity are also formed on the side wall of the mounting knife holder.

[0010] Preferably, a set of symmetric fixing rods are fixedly installed inside the inner cavity, and a compression spring is sleeved on the outside of the fixing rod. A set of symmetric connection holes are formed on the side wall of the movable plate, and the movable plate is movably installed with the fixing rod through the connection holes.

[0013] In the present utility model, a cutting mechanism is provided. The cylinders symmetrically arranged on the top surface of the concave support frame are opened, and the output ends push the mounting tool holder in opposite directions. After the mounting tool holder slides on the top surface of the concave support frame through the T-shaped sliding block on the bottom surface, the cutting knives mounted on the opposite side walls of the symmetrically arranged mounting tool holders will cut off the wire after approaching each other, enabling the wire tying machine body to have the function of cutting wires. Manually pulling the C-shaped rod drives the movable plate, and the movable plate moves along the fixed rod through the connection hole, forcing the compression spring to retract, driving the limiting rod out of the limiting hole, and then the cutting knife can be taken out from the mounting port.

Thus, when the cutting knife is worn after long-term use, the purpose of facilitating the quick disassembly, installation and replacement of the cutting knife can be achieved. The disassembly and installation operations are simple and convenient, thereby improving the processing efficiency. Description of the Drawings

A pair of symmetric fixed rods 11 are also fixedly connected inside the mounting knife holder 6, and the compression spring 12 is sleeved on the fixed rod 11. The movable plate 13 is movably connected to the fixed rod 11 through a connection hole 14 on the side wall, and the movable plate 13 is also fixedly connected to the inner end of the compression spring 12. Symmetric limiting rods 15 are fixedly connected to the inner side wall of the movable plate 13, and the movable plate 13 fixedly connects the cutting knife 17 to the mounting opening 7 opened on the mounting knife holder 6 through the limiting rod 15.

[0020] As Figure 2 shown, an inverted concave support frame 3 is fixedly connected to the machine table of the wire tying machine body 1, and a T-shaped sliding groove 4 is opened on the top surface of the concave support frame 3. The T-shaped sliding groove 4 opened on the top surface of the inverted concave support frame 3 is used to cooperate with the sliding of the T-shaped sliding block 19.

[0021] As Figure 2 and 3 shown, a pair of symmetric cylinders 5 are also fixedly installed on the top surface of the concave support frame 3, and a mounting knife holder 6 is fixedly installed on the output end of the cylinder 5. A T-shaped sliding block 19 is fixedly installed on the bottom surface of the mounting knife holder 6, and the T-shaped sliding block 19 is movably installed in the T-shaped sliding groove 4. By turning on the cylinder 5 to drive the output end to push the mounting knife holder 6, after the T-shaped sliding block 19 on the bottom surface of the mounting knife holder 6 slides in the T-shaped sliding groove 4, the wire can be cut off by the cutting knife 17 installed on the mounting knife holder 6.

[0022] As Figure 3 shown, a mounting opening 7 is opened on the inner side wall of the mounting knife holder 6, and an inner cavity 9 is opened inside the mounting knife holder 6. A pair of symmetric side holes 8 are respectively opened on both side walls of the mounting opening 7, and the side holes 8 communicate with the inner cavity 9. A group of through holes 10 communicating with the inner cavity 9 are also opened on the side wall of the mounting knife holder 6. The mounting opening 7 opened on the mounting knife holder 6 is used to enable the cutting knife 17 to be inserted and installed on the mounting opening 7.

The opened through hole 10 enables the C-shaped rod 16 to drive the movable plate 13 to move.

[0023] As Figure 3As shown in the figure, a set of symmetric fixing rods 11 are fixedly installed inside the inner cavity 9, and a compression spring 12 is sleeved outside the fixing rods 11. A set of symmetric connecting holes 14 are opened on the side wall of the movable plate 13, and the movable plate 13 is movably installed with the fixing rods 11 through the connecting holes 14. The movable plate 13 is also fixedly installed with the inner ends of the compression springs 12. A set of symmetric limiting rods 15 are fixedly installed on the inner side wall of the movable plate 13. The limiting rods 15 are inserted and installed in the side holes 8. A C-shaped rod 16 is fixedly installed on the outer side wall of the movable plate 13, and the C-shaped rod 16 passes through the through hole 10.

The C-shaped rod 16 will drive the movable plate 13 to move in the inner cavity 9 opened in the mounting knife seat 6. And the movable plate 13 will move along the symmetric fixed rods 11 installed in the inner cavity 9 through the connecting holes 14 opened on the side wall, and force the compression springs 12 sleeved on the fixed rods 11 to make a retraction operation during the movement. Continuously pull the C-shaped rod 16 until the limiting rod 15 installed on the inner side wall of the movable plate 13 moves into the inner cavity 9 through the side hole 8 and moves out of the limiting hole 18 opened on the cutting knife 17. And after the C-shaped rod 16 can no longer be pulled, pull out the cutting knife 17 from the mounting opening 7 opened on the inner side wall of the mounting knife seat 6. Then, insert the new cutting knife 17 into the mounting opening 7, release the pulling force on the C-shaped rod 16, and the compression spring 12 will perform an elastic stretching and restoring operation and push the movable plate 13 in the inner direction. The movable plate 13 moves in the inner cavity 9 along the fixed rods 11 through the connecting holes 14 until the limiting rod 15 installed on the inner side wall of the movable plate 13 is inserted into the side holes 8 opened on both side walls of the mounting opening 7 and passes through the limiting hole 18 opened on the side wall of the cutting knife 17 in the mounting opening 7. Then, the disassembly, assembly and replacement operation of the cutting knife 17 can be completed, so as to achieve the purpose of facilitating the quick disassembly, assembly and replacement of the cutting knife 17. The disassembly and assembly operation is simple and convenient, thereby improving the processing efficiency.
