[0002] It is one of the core pieces of equipment in a pulp bale conveying and packaging line, used to complete the wire binding function of pulp bales to facilitate subsequent storage and transportation. The processing of the wire wrapped around the pulp bale in the wire binding machine includes twisting the wire, cutting the twisted wire, and ejecting it. In existing wire binding mechanisms, the above-mentioned wire processing structures are basically driven by separate structures, resulting in a slow processing cycle and failing to meet the needs of high-volume pulp bale conveying and packaging lines.

[0003] Therefore, to address the above problems, we provide a processing mechanism for wire kinking. By mechanically linking the above steps, it uses a single power source to drive the wire kinking, shearing, and ejection sequentially, thus accelerating the processing cycle of the wire when assembled in a wire bundling machine.

[0046] Example 1:

[0047] Please see Figures 1-8 The present invention provides a processing mechanism for kinked iron wire, comprising:

[0048] Mounting bracket 201, the top of mounting bracket 201 is provided with wire channel 202;

[0049] The twisting assembly 203 is installed on the path of the wire channel 202, and includes a twisting gear 2031 installed on the path of the wire channel 202. The center of the twisting gear 2031 is provided with a twisting hole 2032 for wire to pass through, corresponding to the wire channel 202. The surface of the twisting gear 2031 is provided with a wire outlet 2033 communicating with the twisting hole 2032. The wire located in the twisting hole 2032 can be removed through the wire outlet 2033.

[0050] The kink assembly 203 also includes a transmission gear 2034, which is rotatably connected to the mounting bracket 201 via a swing shaft 2035.

[0051] The shearing assembly 204 includes a shearing arm 2041, which can carry a cutter and move toward the wire channel 202 to cut the wire in the wire channel 202.

[0052] The ejector rod 205 is used to eject the wire from the kink hole 2032 located in the kink gear 2031.

[0053] The drive assembly 206 can control the kink assembly 203, the shear assembly 204 and / or the ejector rod 205 in a coordinated manner.

[0054] The shear arm 2041 is rotatably mounted on the mounting bracket 201, and the shear arm 2041 is equipped with a first return spring 2042 for automatically resetting the shear arm 2041 after rotation, and a limit stop 2043 for limiting the shear arm 2041. The limit stop 2043 is installed on the other side of the first return spring 2042. The thrust of the first return spring 2042 causes the shear arm 2041 to be in a specific position without external force driving it. For example, in this embodiment, the shear arm 2041 is kept horizontal.

[0055] The drive assembly 206 includes a first drive rod 2061 and a cam 2063; the first drive rod 2061 is mounted on the cam 2063 and swings with the cam 2063; the transmission gear 2034 has a drive groove 2036 inside for mounting the first drive rod 2061; by the swinging of the first drive rod 2061 in the drive groove 2036, the transmission gear 2034 swings about the swing shaft 2035 as the axis, thereby driving the twisted gear 2031 to rotate the twisted wire;

[0056] The drive assembly 206 also includes a second drive rod 2062, and the mounting bracket 201 is also provided with an active hole 2065 for the second drive rod 2062 to move. The second drive rod 2062 is also provided with a second return spring 2066.

[0057] In the initial state of the shear arm 2041 in the shear assembly 204, it overlaps with the end portion of the movable hole 2065 to form a force-bearing part 2045.

[0058] The cam 2063 is provided with a shearing step 20631 for moving the second drive rod 2062 to actuate the shearing arm 2041. When the cam 2063 moves the second drive rod 2062 to the end of the movable hole 2065, it will actuate the shearing arm 2041 to rotate and shear the wire.

[0059] The ejector rod 205 is fixedly connected to the cam 2063. The kink hole 2032 and the wire outlet 2033 of the kink gear 2031 intersect on the movement trajectory of the ejector rod 205 under the rotation drive of the cam 2063. After the shearing step 20631, a first transition arc 20632 is provided to prevent the rotation of the cam 2063 from being restricted by the second drive rod 2062.

[0060] Working principle:

[0061] S1. When the cam 2063 rotates, the first drive rod 2061 will move in the drive groove 2036 of the transmission gear 2034, which will simultaneously drive the transmission gear 2034 to rotate the toggle gear 2031 and make the second drive rod 2062 contact the shear step 20631.

[0062] S2. Then the cam 2063 continues to rotate, and the shearing step 20631 on the cam 2063 slides over the second drive rod 2062, so that the second drive rod 2062 moves in the movable hole 2065 to contact the force-bearing part 2045 of the shearing arm 2041, and pushes the shearing arm 2041 to rotate to shear the wire.

[0063] S3. When the cam 2063 drives the first drive rod 2061 to actuate the transmission gear 2034 and the second drive rod 2062 to actuate the shearing arm 2041, the ejector rod 205 rotates. After the shearing arm 2041 is actuated, the cam 2063 can continue to carry the ejector rod 205 to rotate through the first transition arc 20632 until it passes through the wire channel 202, thereby automatically ejecting the wire located in the wire channel 202 and the kink hole 2032 of the kink gear 2031. It should be noted that the kink hole 2032 and the wire outlet 2033 of the kink gear 2031 intersect on the movement trajectory of the ejector rod 205 under the rotation drive of the cam 2063, thereby ensuring that the ejector rod 205 can eject the wire located in the kink hole 2032 through the wire outlet 2033.

[0064] Therefore, by mechanically linking the twisting, shearing, and ejection of the wire, a single power source 208 can drive the twisting, shearing, and ejection of the wire sequentially. This can speed up the processing cycle of the wire in the wire bundling machine equipped with this device. Furthermore, the twisting assembly 203, shearing assembly 204, ejection rod 205, and drive assembly 206 are all integrated and mounted on the mounting frame 201, effectively saving installation space. This device can also be used to address faults caused by twisting, shearing, or ejection in existing wire bundling machines by directly replacing the equipment, thereby reducing maintenance time on the production line.

[0065] In this embodiment, after removing the shearing component 204 or the ejector rod 205 separately, the processing cycle can still be effectively improved compared to the existing kink assembly 203, shearing component 204 and ejector rod 205 being driven by the power source 208 alone. Therefore, mechanically linking the shearing component 204 with the kink assembly 203, or mechanically linking the ejector rod 205 with the kink assembly 203, is within the protection scope of this embodiment.

[0066] Example 2:

[0067] Please see Figures 1-8 As a further improvement to Embodiment 1, unlike Embodiment 1, a cover plate assembly 207 is also installed on the mounting frame 201. The cover plate assembly 207 includes a limiting cover plate 2071 that covers the wire channel 202 to guide and limit the wire. The two sides of the limiting cover plate 2071 are rotatably connected to the swing shaft 2035 through the swing arm 2072, and the second drive rod 2062 is installed on the swing arm 2072.

[0068] When the limiting cover plate 2071 covers the wire channel 202, the second drive rod 2062 of the swing arm 2072 is in contact with the cam 2063 in the initial state. The cam 2063 is provided with a cover-removing step 20633 for driving the second drive rod 2062 to rotate the swing arm 2072. A second transition arc 20634 is provided between the cover-removing step 20633 and the shearing step 20631.

[0069] Working principle:

[0070] S1.1 When the cam 2063 rotates and causes the second drive rod 2062 to slide over the cover removal step 20633, the second drive rod 2062 carries the limiting cover plate 2071 to rotate initially through the swing arm 2072. At this time, the second drive rod 2062 moves from the beginning end of the movable hole 2065 to the middle end.

[0071] S1.2 As the cam 2063 continues to rotate, the first drive rod 2061 will move in the drive groove 2036 of the transmission gear 2034, and cause the transmission gear 2034 to drive the twisted gear 2031 to rotate. At the same time, the second transition arc 20634 in the cam 2063 slides over the second drive rod 2062, and causes the second drive rod 2062 to contact the shear step 20631.

[0072] S2. Then, the cam 2063 continues to rotate, and the shearing step 20631 on the cam 2063 slides over the second drive rod 2062, thereby causing the second drive rod 2062 to move in the movable hole 2065 until it contacts the force-bearing part 2045 of the shearing arm 2041, and actuates the shearing arm 2041 to rotate to shear the wire; the second drive rod 2062 can move further through the swing arm 2072 carrying the limiting cover plate 2071 to its end in the movable hole 2065. This releases the limitation of the limiting cover plate 2071 on the wire channel 202.

[0073] S3. When the cam 2063 drives the first drive rod 2061 to move the transmission gear 2034 and the second drive rod 2062 to move the shearing arm 2041, the ejector rod 205 rotates. After the shearing arm 2041 is moved, the cam 2063 can continue to carry the ejector rod 205 to rotate through the first transition arc 20632 until it passes through the wire channel 202, thereby automatically ejecting the wire located in the wire channel 202 and the kink hole 2032 of the kink gear 2031.

[0074] In Embodiment 1 and Embodiment 2, the width of the wire channel 202 is adapted to twice the diameter of the wire, and the height of the wire channel 202 is adapted to the diameter of the wire.

[0075] The kink hole 2032 in the kink gear 2031 is equivalent to the wire channel 202, and the wire outlet 2033 in the kink gear 2031 is on the same horizontal plane as the kink hole 2032. This ensures that the kink gear 2031 guides and limits the wire. In the above embodiment, when the ejector rod 205 ejects the wire, the transmission gear 2034 rotates several times and then rotates 90 degrees so that its horizontally set kink hole 2032 faces upward.

[0076] The shearing arm 2041 has a shearing groove 2044 that matches the diameter of the wire, which ensures that only one wire is cut during actual use.

[0077] A guide rod 2067 is mounted on the cam 2063, and a guide hole 2064 for sliding of the guide rod 2067 is provided on the mounting bracket 201, which ensures the movement trajectory of the cam 2063.

[0078] The cam 2063 is driven to rotate by the power source 208. The power source 208 is preferably a hydraulic rod or a pneumatic rod that drives the cam 2063 via a rocker arm. When a hydraulic rod is used, all the above steps can be completed with only a small hydraulic rod stroke.

[0079] It is important to note that when the wire is twisted in this processing mechanism, both ends of the wire located in the wire channel 202 need to be locked. The locking structure can adopt the structure found in existing wire bundling machines. For example, existing conventional wire bundling machines use a hydraulic rod to drive a swing arm to clamp the beginning of the wire, while the end of the wire is locked by pulling back through other structures. Of course, other existing wire locking mechanisms can also be used in conjunction with this processing mechanism; other existing technical solutions will not be elaborated here.

[0080] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made to the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
