Description

Technical Field

[0001] This invention relates to an integrated compression and baling machine for loose materials, belonging to the field of packaging machinery technology. Background Technology

[0002] Currently, resources such as sawdust, various types of peat, organic mulch, and straw fiber are widely used in agriculture and animal husbandry. Two main packaging methods are used in the market: First, direct packaging of bulk materials. This method results in less material per unit volume, lighter weight, higher transportation costs, and is not conducive to storage. Second, compressing these compressible and cohesive materials into smaller blocks. First, hydraulic cylinders compress the bulk material into blocks, and then downstream equipment bundles or packages the blocks. While this method can reduce some transportation costs and improve storage space utilization compared to the first method of direct bulk packaging, the compressed blocks become larger due to the springback properties of loose materials after compression. Furthermore, small fragments are easily shed during subsequent packaging processes, causing equipment malfunctions and polluting the working environment, affecting equipment stability and efficiency. Summary of the Invention

[0003] To address the problems of low efficiency and high transportation and storage costs in existing loose material packaging equipment, this invention proposes an integrated compression and baling machine for loose materials. It includes a main frame with a vertically arranged cavity at the top and bottom openings in the center. A feed inlet is located on the upper rear wall of the cavity. A matching extrusion plate is installed inside the cavity, with its upper end connected to the cylinder rod of a vertically arranged extrusion cylinder. The cylinder body of the extrusion cylinder is connected to the upper end of the main frame. The extrusion cylinder drives the extrusion plate to move downwards along the inner wall of the cavity, compressing the loose material into dense, large pieces. Two sets of lifting cylinders are symmetrically arranged on the left and right sides of the cavity, with their cylinder rods hinged to the outer wall of the cavity. The cylinder body is hinged to the upper end of the main frame. A wrapping cylinder is provided at the lower end of the cavity. The inner cavity size of the wrapping cylinder is the same as that of the cavity and the outer wall is smooth. A ring-rail type wrapping mechanism is provided on the outer side of the wrapping cylinder. The upper end of the wrapping mechanism is fixed on the cavity. Two sets of flipping heat sealing mechanisms that rise and fall with the cavity are symmetrically provided on the front and rear sides of the outer side of the wrapping mechanism. The upper end of the flipping heat sealing mechanism is hinged to the lower end of the telescopic rod. The upper end of the telescopic rod is hinged to the outer wall of the cavity. The lifting cylinder can drive the cavity and the wrapping mechanism to rise and fall. It can also drive the flipping heat sealing mechanism to move up and down along the vertical beam of the main frame through the telescopic rod. When the cavity is in the upper position, the flipping heat sealing mechanism is located below the cavity and can be heat-sealed and melted after flipping.

[0004] Four sets of guide wheels are symmetrically arranged around the outer wall of the cavity, and the guide wheels roll up and down along the vertical beam of the main frame.

[0005] The film wrapping mechanism includes a hanger connected to the cavity. A ring track is provided below the hanger, and the vertical center line of the ring track coincides with the vertical center line of the wrapping cylinder. Multiple sets of guide pulleys are evenly distributed along the circumference of the ring track at the lower end of the hanger. The ring track is embedded between the guide pulleys. Two sets of film supply mechanisms are symmetrically provided at the lower end of the ring track. Film rolls are installed on the film supply mechanisms. The ring track and the film supply mechanisms are driven by a drive mechanism to achieve circumferential movement along the guide pulleys.

[0006] The flipping heat sealing mechanism includes a lifting frame, the upper end of which is hinged to one end of a telescopic rod, the upper part of which is hinged to the upper end of a swing frame, the middle part of which is hinged to the cylinder rod of a flipping cylinder, the cylinder body of which is hinged to the lifting frame, and the flipping cylinder drives the swing frame to swing up and down. A movable frame is also provided on the swing frame, and a heat sealing plate is provided at the lower end of the movable frame. The movable frame is driven by a heat sealing movable cylinder to move horizontally along the swing frame, and the cylinder body of the heat sealing movable cylinder is hinged to the swing frame.

[0007] A belt conveyor that can move horizontally back and forth is provided on one side of the feed inlet. A storage box with openings at the top and bottom is provided on the upper end of the belt conveyor. When the belt conveyor moves to the front position, its front part can extend into the feed inlet.

[0008] The left side of the main frame is equipped with a tray pushing mechanism, which can push the tray to the bottom of the cavity.

[0009] The beneficial effects of this invention are:

[0010] A. Loose material is fed into the mold cavity. The extrusion plate, driven by the extrusion cylinder, compresses the loose material into high-density bulk material. Then, the lifting cylinder drives the mold cavity and the wrapping film mechanism to rise, causing the wrapping film mechanism to wrap around the wrapping cylinder. At this time, the lower part of the compressed bulk material begins to detach from the mold cavity, and as the wrapping film mechanism rises, the film wrapped on the wrapping cylinder immediately wraps around the bulk material. When the mold cavity rises to the upper position, it completely detaches from the bulk material. At this time, the flipping heat sealing mechanism flips to the bottom of the mold cavity to heat and melt the film, completing the wrapping and sealing of the bulk material. Its overall structure is simple and can compress hundreds of kilograms to tons of loose material with resilience into blocks and directly wrap and pack them according to the characteristics of the material and actual needs. This improves the overall packing efficiency, further reduces transportation costs, and increases storage utilization. The wrapping of the compressed bulk material as it begins to detach from the mold cavity also avoids the problem of the bulk material loosening again and falling small fragments after leaving the mold cavity. It is suitable for various compressible and adhesive materials with high resource utilization needs.

[0011] B. The stretch film mechanism is equipped with two sets of film supply mechanisms, which can simultaneously wrap film around the stretch film tube, further improving the efficiency of stretch film packaging.

[0012] C. By utilizing the coordination of the telescopic pull rod and the flipping heat sealing mechanism, the flipping heat sealing mechanism can remain stationary when the cavity rises. After the telescopic pull rod is extended to its full position, the cavity continues to rise, driving the flipping heat sealing mechanism to rise as well. This ensures that the flipping heat sealing mechanism can complete the heat sealing and melting action below the large pressure cavity. The lower heat sealing film after melting ensures that the upper part of the large material is completely packaged. The upper heat sealing film serves as the bottom seal for the next set of large material wrapping, improving the reliability of wrapping and packaging large material.

[0013] D. A belt conveyor that can move horizontally back and forth is provided on one side of the feed inlet. When conveying materials into the cavity, the belt conveyor can extend into the feed inlet, which effectively ensures the accuracy of feeding. Attached Figure Description

The embodiments are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] The purpose of this invention is to provide an integrated compression and baling machine suitable for large bulk materials. See [link / reference]. Figures 1-5It includes a main frame 1, with a vertically arranged rectangular cavity 2 with openings at both ends in the middle of the main frame 1. A feed inlet A is located on the upper part of the rear side wall of the cavity 2.

The cylinder body of the extrusion cylinder 8 is connected to the upper end of the main frame 1. The extrusion cylinder 8 can drive the extrusion plate 7 to move downwards along the inner wall of the cavity 2, compressing the loose material inside into dense, large pieces.

A rectangular wrapping cylinder 21 is located at the lower end of the cavity 2. The inner cavity of the wrapping cylinder 21 is the same as that of the cavity 2 and the outer wall is smooth. A ring-rail type wrapping mechanism 3 is provided on the outer side of the wrapping cylinder 21. The upper end of the wrapping mechanism 3 is fixed on the cavity 2. Two sets of flipping heat sealing mechanisms 4 are symmetrically provided on the front and rear sides of the outer side of the wrapping mechanism 3, which rise and fall with the cavity 2. The upper end of the flipping heat sealing mechanism 4 is hinged to the lower end of the telescopic rod 5. The upper end of the telescopic rod 5 is hinged to the outer wall of the cavity 2. The lifting cylinder 9 can drive the cavity 2 and the wrapping mechanism 3 to rise and fall, and can drive the flipping heat sealing mechanism 4 to move up and down along the vertical beam of the main frame 1 through the telescopic rod 5. When the cavity 2 is in the upper position, the flipping heat sealing mechanism 4 is located below the cavity 2 and can be heat-sealed and melted after flipping.

[0023] Furthermore, four sets of guide wheel sets 6 are symmetrically arranged around the outer wall of the cavity 2. The guide wheel sets 6 roll up and down along the vertical beam of the main frame 1. The guide wheels in the guide wheel sets 6 have grooves and abut against the inner bending part of the vertical beam of the main frame 1. Multiple sets of observation ports 22 are symmetrically arranged on the left and right side walls of the cavity 2 for detecting the position of the material.

[0024] Furthermore, the wrapping film mechanism 3 includes a hanger 31 connected to the cavity 2. A ring track 36 is provided below the hanger 31, and the vertical center line of the ring track 36 coincides with the vertical center line of the wrapping film cylinder 21. Multiple sets of guide pulleys 35 are evenly distributed along the circumference of the ring track 36 at the lower end of the hanger 31. The ring track 36 is embedded between the guide pulleys 35. Two sets of film supply mechanisms 32 are symmetrically provided at the lower end of the ring track 36. Film rolls 37 are installed on the film supply mechanisms 32. The ring track 36 and the film supply mechanisms 32 are driven by the drive mechanism 33 to achieve circumferential movement along the guide pulleys 35. Preferably, the drive mechanism 33 is a motor-driven synchronous belt transmission mechanism.

[0025] Furthermore, the flipping heat sealing mechanism 4 includes a lifting frame 41, the upper end of which is hinged to one end of the telescopic rod 5, the upper part of which is hinged to the upper end of the swing frame 42, the middle part of which is hinged to the cylinder rod of the flipping cylinder 43, the cylinder body of which is hinged to the lifting frame 41, the flipping cylinder 43 drives the swing frame 42 to swing up and down, the swing frame 42 is also provided with a moving frame 46, the lower end of which is provided with a heat sealing plate 44, the moving frame 46 is driven by a heat sealing moving cylinder 45 to move horizontally along the swing frame 42, the cylinder body of which is hinged to the swing frame 42; the heat sealing plate 44 is provided with clamping rods on both sides for flattening and clamping the heat sealing part of the film before heat sealing, the lifting frame 41 is provided with rollers at both ends, the rollers are tangent to the vertical beam of the main frame 1 and can roll up and down along the vertical beam.

[0026] Furthermore, a belt conveyor 10 that can move horizontally back and forth is provided on one side of the feed inlet A. The upper end of the belt conveyor 10 is provided with a storage box with openings at the top and bottom. When the belt conveyor 10 moves to the front position, its front part can extend into the feed inlet A. Preferably, a horizontal hydraulic cylinder is provided at the lower end of the belt conveyor 10. The horizontal hydraulic cylinder drives the belt conveyor 10 to move back and forth, and the storage box is connected to the upstream unloading mechanism.

[0027] Furthermore, a pallet pushing mechanism 10A is provided on the left side of the main frame 1. The pallet pushing mechanism 10A can push the pallet to the bottom of the cavity 2. The pallet pushing mechanism 10A is provided with a movable push plate, which can push the pallet at the bottom of the pallet compartment and push it to the bottom of the cavity 2.

[0028] See Figures 1 to 7 The working principle of this embodiment is explained as follows:

[0029] The pallet pushing mechanism 10A pushes the pallet at the bottom of the pallet compartment to the bottom of the cavity 2. When the cavity 2 descends to the low position, the lower end of the wrapping cylinder 21 falls on the pallet. The belt conveyor 10 moves horizontally forward and extends into the feed port A. The belt conveyor 10 is started to transport the loose material in the storage box into the cavity 2.

[0030] After the material feeding is completed, the belt conveyor 10 returns to the initial position, and the extrusion cylinder 8 drives the extrusion plate 7 to move downward to extrude the loose material inside into dense large pieces of material.

[0031] The lifting cylinder 9 drives the cavity 2 and the wrapping film mechanism 3 to rise, the telescopic rod 5 extends outward, the driving mechanism 33 drives the annular track 36 and the film supply mechanism 32 to move in a circular motion, so that the film roll 37 in the film supply mechanism 32 wraps around the wrapping cylinder 21 and, as the cavity 2 rises, the wrapped film detaches from the wrapping cylinder 21 and finally wraps around the large piece of material that has detached from the cavity 2. After the telescopic rod 5 extends to the position, as the cavity 2 rises further, it drives the flipping heat sealing mechanism 4 to move upward along the vertical beam of the main frame 1.

[0032] When cavity 2 is raised to the upper position, it completely separates from the large piece of material. Two sets of flipping cylinders 43 drive the swing frame 42 to swing upward 90 degrees, so that the heat-sealing plate 44 swings to a horizontal state. The heat-sealing moving cylinder 45 drives the moving frame 46 to move horizontally to the middle so that the heat-sealing plate 44 clamps the film. The heat-sealing plate 44 starts to heat up to heat-seal and melt the film to complete the packaging.

[0033] Once the large pieces of material have been packaged, they are pushed out to begin the next work cycle.
