Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, and in particular to a waste compression and baling equipment and baling method. Background Technology

[0002] With the continuous improvement of industrial production and urban living standards, the amount of various recyclable waste materials and general solid waste generated is constantly increasing. In order to reduce transportation costs and facilitate storage and subsequent recycling, it is usually necessary to compress and package the waste materials. Therefore, waste compression and baling equipment is widely used in the fields of renewable resource recycling, logistics warehousing, and waste treatment.

[0003] Existing waste paper compression and baling equipment typically uses a hydraulic cylinder-driven vertical compression method to squeeze and compress waste paper piled in the waste bin, shaping it into waste paper blocks. These blocks are then bound together with strapping wire (such as plastic strapping or metal wire) to maintain their shape. The binding process often employs a semi-automatic threading mechanism.

[0004] However, due to the limited internal space of the compression chamber and the high pressure on the waste material during compression, the binding wire needs to bypass the bottom structure or compression mechanism. This results in high resistance during threading, making it difficult to accurately thread the wire into the appropriate position, and easily leading to threading failures or wire jamming. Furthermore, some automatic binding structures are designed for specific shapes of compression equipment and blocks, lacking flexibility and incurring high costs. Therefore, existing waste compression and baling equipment generally suffers from difficulties in threading the binding wire and insufficient reliability, hindering improvements in baling efficiency and user experience. Summary of the Invention

[0005] The purpose of this invention is to provide a waste compression and baling device and a baling method, which solves the problems of difficulty in threading the binding wire and insufficient reliability in existing waste compression and baling devices.

[0006] To achieve this objective, the present invention adopts the following technical solution: A waste compression and baling device includes a frame, a compression chamber connected to the frame, and a compression plate disposed above the compression chamber. The compression chamber is formed by a bottom base plate disposed below the frame, a first discharge chamber door and a second discharge chamber door disposed opposite to each other, and two side plates disposed opposite to each other. Along the direction from the first discharge chamber door to the second discharge chamber door, a first groove is provided on the bottom base plate, and a second groove is provided on the upper surface of the compression plate. A threading roller is provided in the first groove, and a threading groove is opened along the entire length of the threading roller. The binding thread is threaded through the threading groove. The threading roller is configured to be rotatable so that the opening direction of the threading groove is toward or away from the opening of the first groove. The second groove is provided with a threading tube, and the outer wall of the threading tube is provided with a wire outlet along its length. The threading tube is provided with a threading part, which is used to clamp the free end of the binding wire and drive the free end of the binding wire to move at both ends of the threading tube.

[0007] Optionally, the first groove and the second groove are arranged along the first direction, and multiple first grooves and second grooves are spaced apart along the second direction. Two sets of threading rollers and threading cylinders are symmetrically arranged, and the first direction is perpendicular to the second direction.

[0008] Optionally, a fixing seat can be detachably provided in both the first groove and the second groove, and the threading roller and the threading cylinder are rotatably disposed in the fixing seat.

[0009] Optionally, the threading roller is provided with a wire clamping portion at both ends, the wire clamping portion comprising: A fixed shaft is fixed to the end of the threading roller; The first wire clamp is rotatably sleeved on the fixed shaft and fixed relative to the bottom base plate. The first wire clamp has a wire-passing ring groove, which is connected to the outer wall of the first wire clamp. The opening of the wire-passing ring groove is always set towards the direction of the compression plate. The second wire clamp is fixedly sleeved on the fixed shaft, and the second wire clamp has a wire passage notch; When the opening of the threading groove deviates from the opening direction of the first groove, the binding wire contacts the bottom of the thread-passing ring groove and the bottom of the thread-passing notch, and the first wire clamp and the second wire clamp cooperate to clamp the binding wire.

[0010] Optionally, a rotary drive unit is provided on the bottom substrate. The rotary drive unit includes a sliding rack and drive teeth provided on the outer wall of the second wire clamp. The drive teeth mesh with the sliding rack. A protective cover is fixed on the bottom base plate. The first wire clamp, the second wire clamp, and the sliding rack are all located inside the protective cover. The sliding rack is fixedly connected to a push rod. The end of the push rod passes through the protective cover and is located outside the protective cover. A strip-shaped hole is correspondingly opened on the protective cover.

[0011] Optionally, the threading portion includes: A rotating wire clamp is movably disposed in the wire threading tube and can rotate around an axis and slide along a first direction within the wire threading tube. A first wire groove is provided on the rotating wire clamp. A sliding wire clamp is coaxially arranged with the rotating wire clamp and slidably disposed in the wire threading tube. The rotating wire clamp is provided on both sides. A second wire groove is provided on the rotating wire clamp. The opening of the second wire groove is always kept in communication with the wire outlet. The driving component drives the rotating wire clamp and the sliding wire clamp to move along the first direction in the wire threading tube.

[0012] Optionally, the sliding clamp has an annular sliding hole, and the threading part further includes: A rotating shaft passes through the annular sliding holes of the sliding clamps on both sides, and the rotating shaft passes through the rotating clamp; A semi-tooth ring is fixed to the sliding clamp and coaxially arranged with the sliding clamp; A gear is fixedly sleeved on the end of the rotating shaft, and the gear meshes with the half gear ring.

[0013] Optionally, the first groove of the rotating wire clamp has a recessed groove at its bottom, and the bottom of the recessed groove also has a sliding groove. The bottom of the sliding groove is inclined along a first direction. The wire threading part further includes: A clamping block is movably disposed within the groove, and the clamping block can move radially along the rotating wire clamp. The clamping block is flush with the bottom of the first wire groove. A sliding wedge is slidably disposed in the groove, and the inclined surface of the sliding wedge is in contact with the inclined surface of the groove, and the top of the sliding wedge is in contact with the clamping block; A drive screw sleeve is fitted onto the rotating shaft and threadedly connected to the rotating shaft. The drive screw sleeve is fixedly connected to the sliding wedge.

[0014] Optionally, a fixing plate is symmetrically fixed on one side of the bottom base plate, and a pull rope is connected between the two fixing plates. The pull rope is symmetrically placed in the two first grooves. Two fixing posts are symmetrically fixed on the side of the compression plate opposite to the fixing plate.

[0015] This invention also provides a packaging method using the waste compression and packaging equipment described above, comprising the following steps: The binding wire is pre-threaded into the threading groove of the threading roller in the first groove, and the threading roller is rotated so that the opening of the threading groove is offset from the opening of the first groove. Close the first and second discharge bin doors, and feed the waste material into the compression chamber. Drive the compression plate to move downwards and compress the waste material in the compression chamber. Open the first and second discharge chamber doors, so that the threading part in the threading tube clamps the free end of the binding wire, and drive the free end of the binding wire to move in the threading tube in the first direction, so that the binding wire passes out from the other end of the threading tube to the outside of the compression chamber, so that the binding wire is located between the compression plate and the bottom substrate and surrounds the waste material forming body. Control the rotation of the threading roller so that the opening of the threading groove faces the opening of the first groove to release the binding thread; Tighten both ends of the binding line and secure them to pack the waste blocks.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Specifically, the compression plate moves vertically up and down to compress and shape the waste material located in the compression chamber. A threading roller is installed in the first groove in a rotatable manner. A threading groove is formed along the entire length of the outer peripheral wall of the threading roller, and the binding wire is pre-threaded into the threading groove. By rotating the threading roller, the opening direction of the threading groove can be made to face the opening of the first groove, so as to facilitate the binding wire entering or leaving the first groove; or the opening direction of the threading groove can be made to deviate from the opening of the first groove, thereby limiting the binding wire and preventing the binding wire from leaving the threading groove during the compression process. A threading cylinder is installed in the second slot, extending along the corresponding direction of the second slot. Its outer wall has a continuous outlet. The threading section clamps the free end of the binding wire, causing it to reciprocate between the two ends of the threading cylinder. This allows the binding wire to be led out from one end of the second slot to the other, wrapping around the compressed block. The two free ends of the binding wire are then tied together to secure it, thus packaging the compressed block. By providing a first slot and a second slot on the compression plate and bottom base plate respectively, and installing a rotatable threading roller and a threading cylinder with a threading section within them, the binding wire can be automatically guided and threaded along a predetermined path within the compression chamber. This ensures that the binding state of the binding wire is always controlled, preventing it from shifting, falling off, or being damaged by waste material. Attached Figure Description

[0030] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0031] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1: like Figures 1-10 As shown, this embodiment of the invention provides a waste compression and baling device for recycling waste paper, cardboard, and other paper waste materials. It aims to provide a waste compression and baling device that is easy to thread and bale. Furthermore, through structural improvements, this embodiment of the invention also has the advantage of improving threading reliability and efficiency.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the waste compression and baling equipment includes a frame 1, a compression chamber 2 connected to the frame 1, and a compression plate 3 disposed above the compression chamber 2. The compression chamber 2 is formed by a bottom base plate 21 disposed below the frame 1, a first discharge chamber door 22 and a second discharge chamber door 23 disposed opposite to each other, and two side plates 24 disposed opposite to each other. A first groove 211 is formed on the bottom base plate 21 along the direction from the first discharge chamber door 22 to the second discharge chamber door 23, and a second groove 3 is formed on the upper surface of the compression plate 3. 1; A threading roller 4 is provided in the first groove 211. A threading groove 41 is opened along the entire length of the threading roller 4. The binding wire is threaded through the threading groove 41. The threading roller 4 is configured to be rotatable so that the opening direction of the threading groove 41 is facing or deviating from the bottom of the first groove 211. A threading tube 5 is provided in the second groove 31. A wire outlet 51 is opened along the entire length of the outer wall of the threading tube 5. A threading part 52 is provided in the threading tube 5. The threading part 52 is used to clamp the free end of the binding wire and drive the free end of the binding wire to move between the two ends of the threading tube 5.

[0035] Specifically, the frame 1 serves as the load-bearing structure of the entire machine. The compression chamber 2 is connected to the frame 1 and is formed by a bottom base plate 21, a first discharge chamber door 22, a second discharge chamber door 23, and two side plates 24. The first discharge chamber door 22 and the second discharge chamber door 23 are arranged opposite each other to discharge waste material bales from different directions after compression and packaging. The side plates 24 are arranged opposite each other and connected to the bottom base plate 21, jointly defining the compression space for the waste material. A compression plate 3 is located above the compression chamber 2. A drive mechanism for driving the compression plate 3 can be installed above the compression chamber 2. The drive mechanism can be a hydraulic cylinder, a linear slide drive, or other similar method. Under the action of the drive mechanism, the compression plate 3 moves up and down vertically to compress and shape the waste material located in the compression chamber 2.

[0036] Meanwhile, along the direction from the first discharge chamber door 22 to the second discharge chamber door 23, a first groove 211 is formed on the bottom substrate 21 in the same direction; correspondingly, a second groove 31 is formed on the upper surface of the compression plate 3. The first groove 211 and the second groove 31 are arranged opposite each other in the vertical direction, thereby forming a channel area for laying the binding wire between the compression plate 3 and the bottom substrate 21. A threading roller 4 is provided in the first groove 211. The threading roller 4 is arranged along the length of the first groove 211 and is rotatably installed in the first groove 211. A threading groove 41 is formed along the entire length of the outer peripheral wall of the threading roller 4, and the binding wire is pre-threaded in the threading groove 41. By rotating the threading roller 4, the opening direction of the threading groove 41 can be made to face the opening of the first groove 211, so that the binding wire can enter or leave the first groove 211; or the opening direction of the threading groove 41 can be made to deviate from the opening of the first groove 211, thereby limiting the binding wire and preventing the binding wire from leaving the threading groove 41 during compression. A threading tube 5 is provided in the second groove 31, which extends along the corresponding direction of the second groove 31, and has a wire outlet 51 along its outer wall; a threading part 52 is provided inside the threading tube 5, which can clamp the free end of the binding wire, and drive the free end of the binding wire to move back and forth between the two ends of the threading tube 5 by means of electric push rod, linear motor or manual push, so that the binding wire can be led out from one end of the second groove 31 to the other end, so that the binding wire wraps around the compressed block, and then the two free ends of the binding wire are tied together to fix it, so that the compressed block can be packaged.

[0037] It should be noted that a winding roller for the binding wire can be provided on the bottom substrate 21. Before compression, the binding wire is pre-threaded in the threading groove 41, and its free end is located outside the threading groove 41. After the waste material is compressed, the free end of the binding wire is inserted into the threading part 52 in the threading cylinder 5 and clamped. Then, the threading part 52 is driven to slide from one end of the threading cylinder 5 to the other end, so that the free end of the binding wire can be led out from the other end of the threading cylinder 5. Then, the binding wire is cut according to the preset size, and the two free ends of the binding wire are tightened and knotted to complete the packaging of the waste block.

[0038] By setting a first groove 211 and a second groove 31 on the compression plate 3 and the bottom base plate 21 respectively, and setting a rotatable threading roller 4 and a threading tube 5 with a threading part 52 therein, the binding wire can be automatically guided and threaded along a predetermined path in the compression chamber 2, so that the binding state of the binding wire is always controlled, preventing the binding wire from deviating, falling off or being crushed by waste materials.

[0039] Furthermore, the first groove 211 and the second groove 31 are arranged along the first direction, and the first groove 211 and the second groove 31 are spaced apart along the second direction. Two sets of threading rollers 4 and threading cylinders 5 are symmetrically arranged, and the first direction is perpendicular to the second direction.

[0040] Specifically, the upper surface of the compression plate 3 has several second grooves 31 extending along the first direction (i.e., the direction from the first discharge chamber door 22 to the second discharge chamber door 23); the bottom substrate 21 has several first grooves 211 extending along the same first direction; wherein, the several first grooves 211 and the several second grooves 31 are arranged at intervals along the second direction (the direction perpendicular to the first direction) to form multiple parallel threading channels. The threading rollers 4 and threading cylinders 5 are symmetrically arranged in two sets. For example, taking the centerline of the compression chamber 2 in the second direction as a symmetrical reference, a set of threading rollers 4 and threading cylinders 5 are arranged on both sides of the centerline, and the binding lines can form binding paths at two symmetrical positions of the compressed molded body, or achieve multiple bindings as needed. This allows the binding lines to form multiple binding straps, enabling multi-point constraint of the waste material bales and reducing the risk of loosening and deformation.

[0041] Meanwhile, both the first groove 211 and the second groove 31 are detachably equipped with a fixing seat 32, and the threading roller 4 and the threading tube 5 are rotatably mounted in the fixing seat 32. Specifically, both the first groove 211 and the second groove 31 are equipped with a detachable fixing seat 32. The fixing seat 32 can be installed in the groove by means of bolt connection, snap-fit ​​limiting, or insertion fit, and can be completely removed when maintaining or changing the binding position. The fixing seat 32 has a cylindrical embedding groove, and the threading roller 4 and the threading tube 5 are rotatably mounted in the corresponding fixing seat 32. Thus, the opening direction of the threading groove 41 can be switched with the rotation of the threading roller 4, and the opening direction of the outlet 51 can be switched with the rotation of the threading tube 5. Therefore, before compression begins, the threading roller 4 and the threading drum 5 can be rotated respectively to make the opening of the threading groove 41 deviate from the opening of the first groove 211 and the opening direction of the outlet 51 deviate from the opening of the second groove 31, thereby preventing the binding wire from detaching from the threading groove 41 or waste material from entering the threading drum 5.

[0042] like Figure 3 , Figure 4 and Figure 6As shown, in this embodiment of the invention, the threading roller 4 has a clamping portion 42 at both ends. The clamping portion 42 includes a fixed shaft 421, a first clamp 422, and a second clamp 424. The fixed shaft 421 is fixed to the end of the threading roller 4. The first clamp 422 is rotatably sleeved on the fixed shaft 421 and is fixed relative to the bottom substrate 21. The first clamp 422 has a thread-passing groove 423, which communicates with the outer wall of the first clamp 422. The opening of the thread-passing groove 423 always faces the direction of the compression plate 3. The second clamp 424 is fixedly sleeved on the fixed shaft 421 and has a thread-passing notch 425. When the opening of the threading groove 41 faces the bottom of the first groove 211, the binding wire contacts the bottom of the thread-passing groove 423 and the bottom of the thread-passing notch 425, and the first clamp 422 and the second clamp 424 cooperate to clamp the binding wire.

[0043] Specifically, a fixed shaft 421 can be fixedly connected to both ends of the threading roller 4, and the fixed shaft 421 is coaxially fixed with the threading roller 4, so that the fixed shaft 421 and the threading roller 4 rotate synchronously. The first wire clamp 422 is rotatably sleeved on the fixed shaft 421, and the first wire clamp 422 is fixed relative to the bottom base plate 21 (for example, the first wire clamp 422 is connected to the bottom base plate 21 through a connecting rod), so that the first wire clamp 422 does not rotate with the fixed shaft 421 when the threading roller 4 rotates; a wire-passing groove 423 is formed on the first wire clamp 422, the wire-passing groove 423 is arranged in a ring around the axis, and one end is radially connected to the outer wall of the first wire clamp 422, so that the binding wire can enter the winding groove, and the opening direction of the wire-passing groove 423 is always set towards the compression plate 3. The second wire clamp 424 is fixedly sleeved on the fixed shaft 421, and the second wire clamp 424 rotates synchronously with the fixed shaft 421. The second wire clamp 424 has a wire-passing notch 425, which is used to form a mating area with the wire-passing ring groove 423 of the first wire clamp 422 in spatial position, so that the binding wire is clamped in the mating area.

[0044] For example, by rotating the second wire clamp 424, the threading roller 4 is rotated, causing the opening of the threading groove 41 on the threading roller 4 to deviate from the bottom direction of the first groove 211. The binding thread is confined in the threading groove 41, and the opening of the threading groove 41 is closed by the fixing seat 32, preventing the binding thread from detaching from the threading roller 4. At the same time, the bottom of the thread-passing ring groove 423 of the first wire clamp 422 and the bottom of the thread-passing notch 425 of the second wire clamp 424 form an arc surface with an arc greater than 180°, thus allowing the two to work together to clamp the binding thread. When the threading roller 4 rotates until the opening of the threading groove 41 faces the opening of the first groove 211, the thread-passing notch 425 of the second wire clamp 424 also faces the opening of the threading groove 41. The clamping effect of the first wire clamp 422 and the second wire clamp 424 on the binding thread is released, allowing the binding thread to be released smoothly.

[0045] Furthermore, a rotary drive unit 43 is provided on the bottom substrate 21. The rotary drive unit 43 includes a sliding rack 431 and a drive tooth 432 provided on the outer wall of the second wire clamp 424. The drive tooth 432 meshes with the sliding rack 431. A protective cover 433 is fixed on the bottom substrate 21. The first wire clamp 422, the second wire clamp 424 and the sliding rack 431 are all located inside the protective cover 433. A push rod 434 is fixedly connected to the sliding rack 431. The end of the push rod 434 passes through the protective cover 433 and is located outside the protective cover 433. A strip-shaped hole is correspondingly opened on the protective cover 433.

[0046] The second wire clamps 424 connected to the two threading rollers 4 symmetrically arranged on the bottom base plate 21 each have driving teeth 432, and the driving teeth 432 of the two second wire clamps 424 mesh with the same rack. Since the second wire clamps 424 are fixedly sleeved on the fixed shaft 421 and rotate synchronously with the fixed shaft 421, when the sliding rack 431 is pushed to move in a linear direction by the push rod 434, the second wire clamps 424 and the threading rollers 4 can be driven to rotate simultaneously, thereby realizing the switching of the opening direction of the threading groove 41 and the clamping / releasing state of the wire clamping part 42. To prevent waste debris from entering the rotary drive part 43 and to improve safety, a protective cover 433 is fixedly provided on the bottom base plate 21, and the first wire clamp 422, the second wire clamp 424 and the sliding rack 431 are all arranged inside the protective cover 433.

[0047] A push rod 434 is fixedly connected to the sliding rack 431. The end of the push rod 434 passes through the cover 433 and extends to the outside of the cover 433. It is used to apply external force to the sliding rack 431. For example, the push rod 434 can be manually pushed or pulled or pushed by an external actuator. A spring can also be set between the sliding rack 431 and the cover 433 so that the sliding rack 431 can automatically reset, so that the threading roller 4 always keeps the threading groove 41 offset from the opening of the first groove 211 in the initial state.

[0048] like Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in this embodiment of the invention, the threading part 52 includes a rotating wire clamp 521, which is movably disposed in the threading tube 5 and can rotate around an axis and slide along a first direction within the threading tube 5. A first wire groove 5211 is provided on the rotating wire clamp 521. A sliding wire clamp 522 is coaxially disposed with the rotating wire clamp 521 and slidably disposed in the threading tube 5. Rotating wire clamps 521 are provided on both sides of the rotating wire clamp 521. A second wire groove 5221 is provided on the rotating wire clamp 521, and the opening of the second wire groove 5221 is always kept in communication with the wire outlet 51. A driving member drives the rotating wire clamp 521 and the sliding wire clamp 522 to move along the first direction in the threading tube 5.

[0049] Specifically, the rotating wire clamp 521 is movably disposed within the threading cylinder 5. The rotating wire clamp 521 is coaxially arranged with the threading cylinder 5 and can rotate around its axis within the threading cylinder 5 to change the clamping wire / conductor posture or the alignment of the wire groove; or, it can slide along a first direction to push the free end of the binding wire to one end of the threading cylinder 5 or pull it back from one end to the other. The rotating wire clamp 521 has a first wire groove 5211 to accommodate the free end of the binding wire for subsequent clamping. The sliding wire clamp 522 is coaxially arranged with the rotating wire clamp 521 and slidably disposed within the threading cylinder 5. A sliding wire clamp 522 is provided at each of the axial ends of the rotating wire clamp 521. The sliding wire clamp 522 has a second wire groove 5221 to provide a stable outlet channel for the binding wire, and the opening direction of the second wire groove 5221 always remains connected to the outlet 51. The driving component is used to drive the rotating wire clamp 521 and the sliding wire clamp 522 to move synchronously in the first direction within the threading drum 5. The driving component can be a linear push-pull structure (e.g., lead screw, push rod 434, etc.), and its output linear displacement is used to realize the conveying of the free end of the binding wire between the two ends of the threading drum 5.

[0050] When the opening directions of the first groove 5211 of the rotating clamp 521 and the second groove 5221 of the sliding clamp 522 are opposite, they together form a circular outline, and the binding wire is located in the circular outline. Thus, the rotating clamp 521 and the sliding clamp 522 can clamp the binding wire. The rotating clamp 521 and the sliding clamp 522 are driven by the driving component to move along the first direction, so that the free end of the binding wire is transported to the target end along the threading cylinder 5. After the free end of the binding wire reaches the end of the threading cylinder 5, the rotating clamp 521 rotates, so that the opening of the first groove 5211 is connected with the outlet 51, and the binding wire can be separated from the threading cylinder 5 and wrapped on the waste block, which is beneficial to improving the threading efficiency.

[0051] Furthermore, the sliding clamp 522 has an annular sliding hole 5222, and the wire threading part 52 also includes: a rotating shaft 523, which passes through the annular sliding holes 5222 of the sliding clamps 522 on both sides, and the rotating shaft 523 passes through the rotating clamp 521; a half-tooth ring 524, which is fixed on the sliding clamp 522 and coaxially arranged with the sliding clamp 522; and a gear 525, which is fixedly sleeved on the end of the rotating shaft 523, and the gear 525 meshes with the half-tooth ring 524.

[0052] Specifically, both sides of the sliding wire clamp 522 are provided with annular sliding holes 5222, which extend in a ring around the central axis of the sliding wire clamp 522. The rotating shaft 523 passes through the annular sliding holes 5222 of the two sides of the sliding wire clamp 522, and passes through the rotating wire clamp 521 and is rotatably connected to the rotating wire clamp 521. The rotating shaft 523 can maintain assembly constraint relative to the sliding wire clamp 522. At the same time, when the sliding wire clamp 522 moves in the first direction in the wire threading tube 5, the rotating shaft 523 and the sliding wire clamp 522 still maintain a stable relative fit relationship. The rotating shaft 523 is arranged along the axial direction of the wire threading tube 5 and passes through the rotating wire clamp 521, thereby structurally connecting the two sides of the sliding wire clamp 522 and the rotating wire clamp 521 into a whole. Half-tooth rings 524 are fixed on both sides of the sliding wire clamps 522. The half-tooth rings 524 are coaxially arranged with the corresponding sliding wire clamps 522, and the outer ring of the half-tooth rings 524 has teeth. A gear 525 is fixedly sleeved on the end of the rotating shaft 523, so that the gear 525 and the rotating shaft 523 rotate synchronously. When the rotating shaft 523 rotates, the gear 525 drives the half-tooth rings 524 to generate a relative rotation tendency. Since the half-tooth rings 524 are fixed on the sliding wire clamps 522, they can drive the rotating wire clamp 521 to rotate, so as to realize the clamping or release of the free end of the binding wire.

[0053] Furthermore, the first groove 5211 of the rotating wire clamp 521 has a groove 5212 on its bottom, and the bottom of the groove 5212 also has a sliding groove 5213. The bottom of the sliding groove 5213 is inclined along the first direction. The wire threading part 52 also includes: a clamping block 526, which is movably disposed in the groove 5212 and can move radially along the rotating wire clamp 521. The clamping block 526 is flush with the bottom of the first groove 5211; a sliding wedge 527, which is slidably disposed in the sliding groove 5213, and the inclined surface of the sliding wedge 527 is in contact with the inclined surface of the sliding groove 5213. The top of the sliding wedge 527 is in contact with the clamping block 526; and a driving screw sleeve 528, which is sleeved on the rotating shaft 523 and threadedly connected to the rotating shaft 523. The driving screw sleeve 528 is fixedly connected to the sliding wedge 527.

[0054] Specifically, a first groove 5211 is formed on the rotating clamp 521, and a second groove 5221 is formed on the sliding clamp 522. When the opening directions of the first groove 5211 and the second groove 5221 are opposite, they can be used to accommodate the free end of the binding wire. A groove 5212 is formed at the bottom of the first groove 5211. The groove 5212 is used to accommodate the clamping block 526 and provide it with radial movement space. A sliding groove 5213 is further formed at the bottom of the groove 5212. The sliding groove 5213 extends along a first direction and its bottom is inclined along the first direction. The clamping block 526 is movably disposed in the groove 5212 and can move radially along the rotating clamp 521. In its initial state, the clamping block 526 is flush with the bottom of the first wire groove 5211, ensuring that the binding wire is not obstructed when placed into the first wire groove 5211. When the clamping block 526 is pushed, it pushes against the inside of the first wire groove 5211, compressing the binding wire and thus clamping it. The sliding wedge 527 is slidably disposed in the slide groove 5213, with its inclined surface fitting against the inclined surface of the slide groove 5213 and its top fitting against the clamping block 526. When the sliding wedge 527 slides in the first direction, its inclined surface engages with the inclined surface of the slide groove 5213, pushing the clamping block 526 radially, causing it to press the binding wire into the first wire groove 5211 and clamp it.

[0055] Meanwhile, the drive sleeve 528 is sleeved on the rotating shaft 523 and threadedly connected to the rotating shaft 523. The cross-section of the drive sleeve 528 can be square or a fixed guide block, so that the drive sleeve 528 will only move linearly along the axis of the rotating shaft 523. The drive sleeve 528 is fixedly connected to the sliding wedge 527, so that the axial displacement of the sleeve can directly drive the sliding wedge 527 to slide along the groove 5213. When the rotating shaft 523 is rotated, the drive sleeve 528 is axially displaced in the first direction, thereby pushing the sliding wedge 527 to move in the first direction, realizing the clamping block 526 clamping the binding wire; when rotated in the opposite direction, the drive sleeve 528 is displaced in the opposite direction, the sliding wedge 527 retracts, the clamping block 526 resets, thereby releasing the binding wire.

[0056] For example, a fixing plate 6 is symmetrically fixed on one side of the bottom base plate 21, and a pull rope 61 is connected between the two fixing plates 6. The pull rope 61 is symmetrically placed in the two first slots 211. On the side of the compression plate 3 opposite to the fixing plate 6, two fixing posts 7 are symmetrically fixed. For example, after compression, the first and second feed chamber doors are opened, and the waste block is bundled with a strapping line. Then, the pull rope 61 is hung on the two fixing posts 7, driving the compression plate 3 to reset upward, thereby causing the waste block to flip and detach from the compression chamber 2, so that the waste block can be transferred to a transfer vehicle for transportation.

[0057] Example 2: This invention also provides a packaging method using the waste compression and packaging equipment described above, comprising the following steps: The binding wire is pre-threaded into the threading groove 41 of the threading roller 4 in the first groove 211, and the threading roller 4 is rotated so that the opening of the threading groove 41 is offset from the opening of the first groove 211. Close the first discharge chamber door 22 and the second discharge chamber door 23, and put the waste material into the compression chamber 2. Drive the compression plate 3 to move downward to compress and shape the waste material in the compression chamber 2. Open the first discharge chamber door 22 and the second discharge chamber door 23, so that the wire threading part 52 in the wire threading tube 5 clamps the free end of the binding wire, and drives the free end of the binding wire to move in the wire threading tube 5 in the first direction, so that the binding wire passes out from the other end of the wire threading tube 5 to the outside of the compression chamber 2, so that the binding wire is located between the compression plate 3 and the bottom base plate 21 and surrounds the waste material forming body; Control the rotation of the threading roller 4 so that the opening of the threading groove 41 faces the opening of the first groove 211 to release the binding wire. Tighten both ends of the binding line and secure them to pack the waste blocks.
