Automatic wire threading hydraulic mechanism of horizontal packing machine

Abstract

This utility model discloses an automatic threading hydraulic mechanism for a horizontal baling machine, belonging to the technical field of baling machines. The automatic threading hydraulic mechanism includes a thread-pushing frame, which is located on one side of the material box. Both sides of the top of the thread-pushing frame are provided with guide shafts for thread-pushing trolleys. A thread-pushing trolley is movably mounted on the guide shaft, and a thread-pushing rod is fixedly mounted on the front side of the trolley. A thread-pushing cylinder is located in the middle. The thrust of the thread-pushing cylinder drives two sets of chain belts to feed the thread-pushing rod, effectively reducing the stroke of the thread-pushing cylinder, optimizing the spatial layout of the threading mechanism, and reducing the space requirements of the threading mechanism. Simultaneously, the thread-pushing trolley slides on the guide shaft and is guided by guide wheels, making the translational movement of the thread-pushing rod smoother, more stable, and the threading more stable and efficient.

Description

Technical Field

[0001] This utility model belongs to the field of baling machine technology, specifically relating to an automatic wire threading hydraulic mechanism for a horizontal baling machine. Background Technology

[0002] Horizontal balers are devices used to compress and bale waste paper, plastics, scrap metal, etc. The wire-threading mechanism is a key component of the horizontal baler, its main function being to ensure that the strapping tape (such as metal wire or plastic tape) can accurately and efficiently pass through the baling material and complete the binding. Existing horizontal balers use a reducer-driven wire-threading mechanism with two full-stroke hydraulic cylinders pushing and pulling, or a single full-stroke hydraulic cylinder with a wire-threading frame at the rear pushing and pulling. This wire-threading mechanism is large in overall size, occupies a large area, and is unstable in its movement, thus affecting the baler's operating efficiency.

[0003] To address this issue, we designed an automatic threading hydraulic mechanism for a horizontal baling machine, providing an alternative technical solution. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic threading hydraulic mechanism for a horizontal baler, so as to solve the problems of existing couplings mentioned in the background art during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic threading hydraulic mechanism for a horizontal baler, comprising a thread pusher frame, the thread pusher frame being disposed on one side of a material box, thread pusher trolley guide shafts being disposed on both sides of the top of the thread pusher frame, a thread pusher trolley being movably mounted on the thread pusher trolley guide shafts, a thread pusher rod being fixedly mounted on the front side of the thread pusher trolley, a pusher head being disposed on the lower side of the thread pusher trolley, a chain and a sprocket being disposed on both sides of the pusher head, and the thread pusher trolley being fixedly connected to the chain, a thread pusher cylinder being disposed on one side of the pusher head to drive the sprocket to rotate, and the chain rotating to drive the thread pusher trolley to slide along the thread pusher trolley guide shaft.

[0006] Preferably, a guide wheel bracket is provided on the side of the wire pushing trolley guide shaft near the material box, and multiple sets of guide wheels are provided on the guide wheel bracket.

[0007] Preferably, the pusher rod body is provided in multiple sets, and the front end of the pusher rod body passes through the guide wheel bracket. Each set of pusher rod bodies is provided with two sets of guide wheels.

[0008] Preferably, the guide shaft of the wire pusher trolley is made of chrome-plated round steel, and a wire pusher head is installed at the front end of the wire pusher rod body, the wire pusher head being used to hook and pick up the binding cable.

[0009] Preferably, the wire-pushing cylinder is located at the center of the pusher head, and the wire-pushing cylinder is infinitely adjustable.

[0010] Preferably, the material box has wire threading holes on both sides, and the wire pusher is provided corresponding to the wire threading holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The pusher cylinder is located in the middle. The pusher cylinder drives the upper and lower chain belts to feed the pusher rod body. This can effectively reduce the stroke of the pusher cylinder, optimize the spatial layout of the threading mechanism, and reduce the space requirements of the threading mechanism. At the same time, the pusher carriage slides on the guide shaft of the pusher carriage and guides the movement of the pusher rod body through the guide wheel limit, making the translational movement of the pusher rod body smoother, more stable, and the threading more stable and efficient.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1-2 An automatic threading hydraulic mechanism for a horizontal baler includes a thread pusher frame 1, which is located on one side of a material box 11. Both sides of the top of the thread pusher frame 1 are provided with thread pusher trolley guide shafts 3. A thread pusher trolley 2 is movably mounted on the thread pusher trolley guide shafts 3. A thread pusher rod 4 is fixedly mounted on the front side of the thread pusher trolley 2. A pusher head 8 is provided on the lower side of the thread pusher trolley 2. A chain belt 13 and a sprocket 5 are provided on both sides of the pusher head 8, and the thread pusher trolley 2 is fixedly connected to the chain belt 13. A thread pusher cylinder 6 is provided on one side of the pusher head 8 to drive the sprocket 5 to rotate. The chain belt 13 rotates to drive the thread pusher trolley 2 to slide along the thread pusher trolley guide shafts 3.

[0018] This technical solution proposes a threading mechanism for a horizontal baler. The threading mechanism has a pusher head 8 equipped with a chain belt 13 and a sprocket 5. The pusher cylinder 6 drives the sprocket 5 to move, which in turn drives the chain belt 13 to move. The chain belt 13 then drives the threading carriage 2 to slide along the guide shaft 3 of the threading carriage, feeding the threading rod 4 into the material box 11 to complete the threading. In this solution, the threading cylinder 6 is located in the middle. The pusher cylinder 6 drives the upper and lower chains 13 to feed the threading rod 4, which can effectively reduce the stroke of the threading cylinder 6, optimize the spatial layout of the threading mechanism, and reduce the space requirements of the threading mechanism. At the same time, the threading carriage 2 slides on the guide shaft 3 of the threading carriage, and the translational movement of the threading rod 4 is smoother, more stable, and the threading is more stable and efficient.

[0019] In one embodiment, a rack is installed at the end of the piston rod of the pusher cylinder 6 to drive the sprocket 5 to rotate, converting the linear motion of the pusher cylinder 6 into the rotation of the sprocket 5. A pinion is set on the sprocket 5 shaft for meshing. The extension and retraction of the cylinder pushes the rack to move linearly, driving the pinion to rotate, thereby driving the sprocket 5 to rotate. In another embodiment, the pusher cylinder 6 directly pushes the sprocket 5 shaft to move laterally through a linear bearing or guide rail, in conjunction with a one-way clutch or ratchet mechanism, and forces the sprocket 5 to rotate by meshing with the chain. In yet another embodiment, a crank is set on the sprocket 5 shaft, and the piston rod of the cylinder is connected to the crank through a hinge. The pusher cylinder 6 pushes and pulls the crank, driving the sprocket 5 shaft to rotate reciprocally.

[0020] Furthermore, a guide wheel bracket 10 is provided on the side of the wire pushing trolley guide shaft 3 near the material box 11, and multiple sets of guide wheels 9 are provided on the guide wheel bracket 10.

[0021] Furthermore, multiple sets of push rod bodies 4 are provided, with the front end of the push rod body 4 passing through the guide wheel bracket 10, and each set of push rod bodies 4 is provided with two sets of guide wheels 9.

[0022] Through this technical solution, the guide wheel bracket 10 uses multiple sets of guide wheels 9 to guide and stabilize the movement of the push rod body 4. Between every two sets of guide wheels 9, a set of push rod bodies 4 is clamped and guided. When the push rod body 4 is driven by the push trolley 2, the guide wheel 9 rotates to limit the movement of the push rod body 4, thereby making the movement of the push rod body 4 more stable, the feeding position does not deviate, and the feeding accuracy is higher.

[0023] Furthermore, the guide shaft 3 of the wire pusher trolley is made of chrome-plated round steel, and the front end of the wire pusher rod body 4 is equipped with a wire pusher rod head 12, which is used to hook and pick up the binding cable.

[0024] The guide shaft 3 of the wire pusher trolley is made of chrome-plated round steel, with a smooth surface, good wear resistance, and more stable guidance; the wire pusher rod head 12 is used to attach the strapping lock and is fed into the material box 11 through the wire pusher rod body 4, used to bundle the waste material compressed and packaged in the baler.

[0025] Furthermore, the wire pusher cylinder 6 is located in the center of the pusher head 8, and the wire pusher cylinder 6 is infinitely adjustable.

[0026] Furthermore, wire threading holes are provided on both sides of the material box 11, and the wire pusher body 4 is set accordingly for the wire threading holes.

[0027] Working principle: The push force of the wire-pushing cylinder 6 drives the sprocket 5 to move, which in turn drives the chain belt 13 to move. The movement of the chain belt 13 drives the wire-pushing carriage 2 to slide along the guide shaft 3 of the wire-pushing carriage, sending the wire-pushing rod 4 into the material box 11 to complete the wire threading. In this scheme, the wire-pushing cylinder 6 is set in the middle. The push force of the wire-pushing cylinder 6 drives the upper and lower chains 13 to feed the wire-pushing rod 4, which can effectively reduce the stroke of the wire-pushing cylinder 6, optimize the spatial layout of the wire threading mechanism, and reduce the space requirements of the wire threading mechanism. At the same time, the wire-pushing carriage 2 slides on the guide shaft 3 of the wire-pushing carriage and is limited and guided by the guide wheel 9 to move the wire-pushing rod 4, making the translational movement of the wire-pushing rod 4 smoother, more stable, and the wire threading more stable and efficient.
