Description

Technical Field

[0001] This utility model relates to the field of material packaging technology, specifically to a wire binding system. Background Technology

[0002] Wire binding machines are one of the core pieces of equipment in pulp bale conveying and packaging lines. They are used to bind pulp bales with wire to facilitate subsequent storage and transportation. Currently, there are very few manufacturers in China that produce wire binding machines for pulp bales, and many rely on imports.

[0003] Currently, most domestic wire bundling machines are used in the construction industry and cannot be directly adapted to pulp board conveying and packaging lines in pulp production. Some machines that can be used in pulp board conveying and packaging lines have slow bundling speeds due to the decentralized driving of functions such as wire twisting, shearing, and ejection, which cannot meet the needs of high-volume pulp board conveying and packaging lines.

[0023] The initial state of the shear arm in the shear assembly overlaps with the end portion of the movable hole to form a force-bearing part;

[0024] The cam is provided with a shearing step for moving the second drive rod to actuate the shearing arm;

[0032] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0033] 1. This utility model, through the iron wire storage and feeding device, the straightening and guiding mechanism, the buffer box, and the iron wire driving mechanism, can simultaneously straighten the iron wire when pulling it, effectively saving the time of straightening the iron wire roll separately, and making it better suited to the needs of high-production pulp board conveying and packaging lines.

[0034] 2.

[0035] 3. This utility model integrates the twisting component, shearing component, ejector rod, and drive component on the mounting frame, thereby effectively saving installation space. It can also directly replace the equipment to handle the faults caused by twisting, shearing, or ejection in the existing wire binding machine, thereby reducing the maintenance time in the production line.

[0036] 4. This utility model improves the feeding and discharging conveyor so that its wire binding mechanism can be directly installed in the conveyor line. Furthermore, by rotating the two conveying mechanisms on the mounting frame, the conveying mechanism can be rotated to the open state, providing maintenance space for the twisting mechanism at the installation station. This facilitates the maintenance of the equipment and reduces the impact of wire binding machine maintenance on the operation of the conveyor line to a certain extent.

[0037] The opening design on the infeed and outfeed conveyors, combined with the rotation of the conveying mechanism, allows the binding machine frame to be directly removed from the opening of the infeed and outfeed conveyors when the wire binding mechanism is difficult to maintain or takes a long time to maintain, and then a new machine can be directly installed, reducing the impact of wire binding machine maintenance on the operation of the conveyor line.

[0080] Example 1:

[0081] Please see Figures 1-11 The wire binding system of this utility model includes:

[0082] The wire storage and feeding device includes, in sequence, a storage mechanism 8, a straightening and guiding mechanism 7, a buffer box 6, and a wire driving mechanism 4;

[0083] The strapping frame 3 is equipped with a wire drive mechanism 4, a wire guide ring frame 5, and a twisting mechanism 2. The twisting mechanism 2 includes a clamping component 209, a twisting component 203, a shearing component 204, an ejector rod 205, and a drive component 206.

[0084] The wire drive mechanism 4 is installed at the feed end of the wire guide ring frame 5, and the wire guide ring frame 5 forms a conveying channel 51 for material to pass through; the wire guide ring frame 5 is provided with an installation port 52 for installing the twisting mechanism 2.

[0085] The feeding and discharging conveyor 1 includes two symmetrically arranged mounting frames 101. The top of each mounting frame 101 is rotatably connected to a conveying mechanism 102. A gap 105 for accommodating a wire guide ring frame 5 is provided between the adjacent ends of the two conveying mechanisms 102, and a mounting groove 103 is provided. The two mounting grooves 103 form a mounting station 104 for mounting the twisting mechanism 2.

[0086] The storage mechanism 8 includes a storage cage 801, inside which is a placement rack 802 for placing wire rolls. The top of the placement rack 802 is detachably connected to a limiting top cover 803, and a limiting rod 804 that overlaps the limiting top cover 803 is installed on the inner side of the storage cage 801.

[0087] The straightening guide mechanism 7 includes a straightening wheel assembly 701 for straightening iron wire installed on the top of the storage cage 801, and a guide tube 702 installed between the straightening wheel assembly 701 and the iron wire drive mechanism 4; the straightening wheel assembly 701 includes two small straightening wheels 7011 and one large straightening wheel 7012, and an S-shaped straightening channel is formed between the two small straightening wheels 7011 and the large straightening wheel 7012;

[0088] The wire drive mechanism 4 includes a drive wheel 409 mounted on a fixed plate 402, a clamping wheel 406 mounted on a movable plate 405, a plurality of guide grooves 404 mounted between the drive wheel 409 and the clamping wheel 406, and a first power source 401 for rotating the drive wheel 409, thereby pulling out or retracting the wire through the rotation of the drive wheel 409.

[0089] The buffer box 6 includes a box body 601 with a cavity 602. The box body 601 is connected to a movable cover plate 603 by a hinge. The movable cover plate 603 has limit blocks 604 at both ends. The two limit blocks 604 and the cavity 602 form a buffer space for accommodating the wire. A limit channel 605 is provided between the limit blocks 604 and the bottom of the inner wall of the cavity 602. The guide tube 702 is set perpendicular to the limit channel 605.

[0090] The movable plate 405 slides relative to the fixed plate 402 via the guide rail 403, and a limit frame 408 is fixedly connected to the side of the guide rail 403 away from the fixed plate 402. A clamping spring 407 is provided between the limit frame 408 and the movable plate 405, as well as a control lever for controlling the sliding of the movable plate 405.

[0091] Several guide grooves 404 are installed on both sides of the drive wheel 409. The guide grooves 404 form a clamping station 4041. The guide grooves 404 on both sides of the clamping station 4041 are provided with slopes 4042 that are adapted to the drive wheel 409 and the clamping wheel 406.

[0092] Working principle:

[0093] In this embodiment, the wire drive mechanism 4, the wire guide ring frame 5, and the twisting mechanism 2 installed on the binding machine frame 3 can all adopt the structure of existing wire binding machines that achieve this function. In this embodiment, this is not a protected innovation point, and the specific structure will not be described in detail here.

[0094] S1. Before use, manually insert the end of the wire into the S-shaped straightening channel in the straightening wheel set 701 between the limiting rods 804, then let the end of the wire pass through the guide tube 702 and through the limiting channel 605 in the buffer box 6, then let the end of the wire pass through the guide groove 404, and let the clamping wheel 406 clamp the wire in conjunction with the clamping spring 407 driving the movable plate 405 and the fixed drive wheel 409.

[0095] S2. When the material enters the conveying channel 51 of the wire guide ring frame 5 through the conveying mechanism 102 on the feed conveyor 1, the material will be located above the twisting mechanism 2. At this time, the wire drive mechanism 4 drives the wire to wrap around the material through the wire guide ring frame 5, and the end of the wire is clamped and locked by the clamping component 209. Then, the wire drive mechanism 4 pulls back the wire to tighten the wire wrapped around the material and lock the tail of the wire.

[0096] S2.1 When the wire is pulled by the wire drive mechanism 4, the wire coil will be straightened under the action of the small straightening wheel 7011 and the large straightening wheel 7012 in the S-shaped straightening channel;

[0097] S2.2 When the wire is pulled back by the wire drive mechanism 4 to tighten the wire wrapped around the material, the wire retracts in the limiting channel 605. Since the guide tube 702 is set perpendicular to the limiting channel 605, the wire will be blocked by the inner wall of the guide tube 702 when it retracts. At this time, when the wire is subjected to the retraction force, it will bend between the two limiting blocks 604 and enter the cavity 602 of the box 601 for storage.

[0098] S3. Then, the wire is twisted, cut, and ejected by the twisting mechanism 2, and then sent out from the other side by the conveying mechanism 102 on the feed conveyor 1.

[0099] Example 2:

[0100] Please see Figures 12-19As a specific embodiment of the knot structure 2, the knot mechanism 2 is different from the embodiment of the first embodiment in that it also includes a mounting bracket 201 installed in the mounting port 52, and the top of the mounting bracket 201 is provided with a wire channel 202.

[0101] The twisting assembly 203 is installed on the path of the wire channel 202, and the twisting assembly 203 includes a twisting gear 2031 installed on the path of the wire channel 202, and a transmission gear 2034 rotatably connected to the mounting bracket 201 via a swing shaft 2035. 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.

[0102] The shearing assembly 204 includes a shearing arm 2041 rotatably mounted on the mounting bracket 201. A first return spring 2042 for automatically resetting the shearing arm 2041 after rotation is mounted on the shearing arm 2041, and a limit stop 2043 for limiting the shearing arm 2041. The limit stop 2043 is mounted on the other side of the first return spring 2042.

[0103] The ejector rod 205 is used to eject the wire from the kink hole 2032 located in the kink gear 2031.

[0104] The drive assembly 206 can be linked to control the kink assembly 203, the shear assembly 204 and / or the ejector rod 205.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] The cam 2063 is provided with a shearing step 20631 for moving the second drive rod 2062 to actuate the shearing arm 2041;

[0109] Cam 2063 is driven to rotate by a second power source 208.

[0110] 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.

[0111] The twisting mechanism 2 also includes a cover plate assembly 207, which includes a limiting cover plate 2071 covering 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. The second drive rod 2062 drives the swing arm 2072 to move the limiting cover plate 2071 by sliding during the second movement.

[0112] 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 retraction step for driving the second drive rod 2062 to rotate the swing arm 2072. A second transition arc 20634 is provided between the retraction step and the shearing step 20631.

[0113] Working principle:

[0114] S3.1 The second power source 208 drives the cam 2063 to rotate. When the cam 2063 rotates, the second drive rod 2062 slides 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.

[0115] S3.2 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.

[0116] S3.3 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 to contact the force-bearing part 2045 of the shearing arm 2041, and to push 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;

[0117] S3.4 The ejector rod 205 rotates 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. 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.

[0118] S3.5, and then it is sent out from the other side through the conveying mechanism 102 on the feed conveyor 1.

[0119] In this embodiment:

[0120] Furthermore, 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.

[0121] 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.

[0122] Furthermore, the shearing arm 2041 is provided with a shearing groove 2044 that matches the diameter of the wire, so that in actual use, only one wire can be sheared.

[0123] 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.

[0124] The cam 2063 is driven to rotate by the second power source 208, preferably by a hydraulic rod or a pneumatic rod. When a hydraulic rod is used, all the above steps can be completed with only a small hydraulic rod stroke.

[0125] In Embodiment 1 and Embodiment 2, the clamping assembly 209 includes a clamping oil rod 2091 mounted on the mounting bracket 201 and a clamping arm 2092 that can swing toward the wire channel 202 to clamp the wire. In use, the end of the wire is clamped by the clamping arm 2092 in the clamping assembly 209, while the tail of the wire is clamped by the wire driving mechanism 4.

[0126] Example 3:

[0127] Please see Figure 5As a further improvement to the feed conveyor 1 in Embodiment 1 or Embodiment 2, the difference is that the conveying mechanism 102 includes a conveyor frame 1021, a drive wheel 1022 and a driven wheel 1023 mounted on the conveyor frame 1021, and a chain 1024 connected between the drive wheel 1022 and the driven wheel 1023. The conveyor frame 1021 is rotatably connected to the mounting frame 101. The conveying mechanism 102 also includes a power component 1026 for driving the drive wheel 1022 to rotate, carrying the chain 1024 and the driven wheel 1023. The power component 1026 is preferably an electric motor. The drive wheel 1022, the driven wheel 1023, and the chain 1024 can also be a drive gear, a driven gear, or a synchronous belt, etc.

[0128] A transmission rod 1025 is mounted on the shaft of the drive wheel 1022. The transmission rod 1025 is mounted on the mounting bracket 101 through a bearing seat. The power component 1026 is connected to the transmission rod 1025 through an electromagnetic clutch. When the power component 1026 is a servo motor, it can be directly connected to the transmission rod 1025.

[0129] One side of the two mounting brackets 101 is fixedly connected by a connecting bracket 107, and the other side has an opening 106 for the removal of the twisting mechanism 2.

[0130] Working principle:

[0131] When maintenance is required on the kinking mechanism 2 located at the installation station 104, the electromagnetic clutch is de-energized, causing the transmission mechanism 102 to rotate around the transmission rod 1025 to the open state, thereby providing maintenance space for the kinking mechanism 2 at the installation station 104.

[0132] If the wire binding mechanism is difficult to repair or takes a long time to repair, in order to avoid the long-term shutdown of the conveyor line, the binding machine frame 3 can be directly removed from the opening 106 of the feed conveyor 1, and then a new machine can be directly installed to reduce the impact of wire binding machine repair on the operation of the conveyor line.

[0133] 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.
