[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The curtain hook wire forming mechanism involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] This utility model provides a curtain hook wire forming mechanism, including a mounting shell 1, on which a traction component 2, a positioning component 3 and a cutting component 4 are mounted.

[0023] The traction assembly 2 includes a rotating rod 21 and a first motor 23. The mounting housing 1 has an internal groove 11, and there are two internal grooves 11. The rotating rod 21 is rotatably installed in the internal groove 11. A conveying roller 22 is fixedly connected to the surface of the rotating rod 21.

[0024] There are two positioning components 3 corresponding to the conveying roller 22. The positioning component 3 includes a positioning roller 31. A fixed rod 32 is rotatably connected to the center of the positioning roller 31. A sliding rod frame 34 is provided at each end of the fixed rod 32. A moving block 33 is fixedly connected to each end of the fixed rod 32.

[0025] The cutting component 4 is located between the two positioning components 3. The cutting component 4 includes a cutting blade 41 and a second motor 43. The output end of the second motor 43 is fixedly connected to a rotating cylinder 42.

[0026] Furthermore, one end of the rotating rod 21 passes through the wall of the built-in groove 11 and extends to the front side of the mounting shell 1. The first motor 23 is fixedly installed on the front side of the mounting shell 1. A power transmission component 24 is provided between the output end of the first motor 23 and one end of the rotating rod 21. Preferably, the power transmission component 24 is a belt drive structure. The power transmission component 24 is used to convert the output power of the first motor 23 into the rotational force of the rotating rod 21.

[0027] Furthermore, the sliding rod frame 34 is fixedly installed on the top of the mounting shell 1, and the moving block 33 is sleeved on the surface of the sliding rod frame 34. The moving block 33 and the axis of the sliding rod frame 34 form a sliding guide fit. The top of the sliding rod frame 34 is fixedly connected to the limiting plate 35, and a compression spring 36 is sleeved on the surface of the sliding rod frame 34. One end of the compression spring 36 is fixedly connected to the top of the moving block 33, and the other end of the compression spring 36 is fixedly connected to the bottom of the limiting plate 35. The elastic force of the compression spring 36 is vertically downward, and this elastic force can drive the positioning roller 31 downward to press and position the steel wire.

[0028] Furthermore, an extension block 44 is fixedly connected to the cutting blade 41. Two extension blocks 44 are symmetrically arranged. A guide rod 45 is sleeved inside the extension block 44. The extension block 44 and the guide rod 45 form a sliding guide fit along the axis of the guide rod 45. The bottom end of the guide rod 45 is fixedly connected to the top of the mounting shell 1. A return spring 46 is sleeved on the surface of the guide rod 45. One end of the return spring 46 is fixedly connected to the bottom of the extension block 44, and the other end of the return spring 46 is fixedly connected to the top of the mounting shell 1. The second motor 43 is fixedly installed on the top of the mounting shell 1. The elastic force of the return spring 46 can drive the extension block 44 to move upward along the guide rod 45.

[0029] Furthermore, the rotating cylinder 42 has guide grooves 421 and reset grooves 422 on its surface. There are two guide grooves 421 and two reset grooves 422. The two guide grooves 421 are connected to each other through the reset grooves 422. A guide post 47 is fixedly connected to an extension block 44. The guide grooves 421 and reset grooves 422 are matched with the guide post 47. When the rotating cylinder 42 rotates around its own axis under the traction of the second motor 43, the extension block 44 can slide down along the guide rod 45 under the guidance of the guide post 47 and the guide groove 421. When the guide post 47 slides to the bottom of the reset groove 422, the second motor 43 is turned off. The elastic force of the reset spring 46 drives the guide post 47 to slide up to the top of the reset groove 422. The extension block 44 returns to the initial position and completes one reciprocating motion.

[0030] Furthermore, a straightening frame 12 is fixedly connected to the top left side of the mounting shell 1. A straightening hole 13 is provided inside the straightening frame 12. During the process of the steel wire passing through the straightening hole 13, the bent steel wire can be straightened. An inclined plate 14 is fixedly connected to the top right side of the mounting shell 1. The inclined plate 14 is used to guide the cut steel wire to be output outward.

[0031] The working principle of this utility model is as follows: When in actual operation, the first motor 23 is turned on, and the first motor 23 drives the rotating rod 21 to rotate around its own axis through the power transmission component 24. The rotating rod 21 rotates and drives the conveying roller 22 to rotate synchronously around the axis of the rotating rod 21.

[0032] The worker passes the steel wire through the straightening hole 13 and inserts it into the area between the left conveyor roller 22 and the positioning roller 31. Under the pressure of the steel wire, the positioning roller 31 moves vertically upward. The movement of the positioning roller 31 drives the moving block 33 to slide synchronously upward along the sliding rod frame 34 through the fixed rod 32. The compression spring 36 contracts under the pressure of the moving block 33 and the limiting plate 35, and the elastic force of the compression spring 36 increases. The compression spring 36 applies a vertical downward force to the positioning roller 31, and the positioning roller 31 presses the steel wire tightly and positions it. At this time, the worker releases the steel wire. Under the traction of the left conveyor roller 22, the steel wire passes through the bottom of the cutting blade 41 and moves to the area between the right conveyor roller 22 and the positioning roller 31. The steel wire presses the right positioning roller 31 upward. Similarly, the positioning roller 31 presses the steel wire tightly and positions it again, and the right conveyor roller 22 continues to pull the steel wire to move.

[0033] During the process of the steel wire passing through the straightening hole 13, the bent steel wire is straightened. When it is necessary to cut the steel wire, the first motor 23 is turned off, the conveying roller 22 stops rotating, the steel wire stops moving, the second motor 43 is turned on, and the second motor 43 drives the rotating cylinder 42 to rotate around its own axis. During the rotation of the rotating cylinder 42, the guide post 47 slides along the guide groove 421. Under the guidance of the guide post 47 and the guide groove 421, the extension block 44 slides down synchronously along the guide rod 45. The return spring 46 increases its elasticity under the compression of the extension block 44, and the cutting blade 41 moves vertically downward to complete the cutting of the steel wire. After the cutting is completed, the guide post 47 slides to the bottom of the return groove 422. At this time, the second motor 43 is turned off, and the elasticity of the return spring 46 drives the guide post 47 to slide upward to the top of the return groove 422. The cutting blade 41 returns to the initial position, thus completing one reciprocating cutting motion.

[0034] The first motor 23 is turned on, and the cut steel wire is output outward along the inclined plate 14 under the traction of the right conveyor roller 22. The steel wire to be cut is then moved to the top of the right conveyor roller 22 under the traction of the left conveyor roller 22. The subsequent steps are the same as above, and the cutting process of the steel wire is continuously completed.

[0035] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
