Description

Technical Field

[0001] This invention relates to the field of sheet metal packaging technology, and in particular to an intelligent sheet metal packaging machine. Background Technology

[0002] With the development of modern industry, sheet metal is increasingly widely used in construction, furniture, and decoration. Protecting the surface of sheet metal from damage and contamination during production and transportation is crucial. Traditional sheet metal packaging methods typically involve manual or semi-automatic operation, resulting in low efficiency, inconsistent packaging quality, and high labor costs. For example, manually wrapping film is prone to wrinkles and omissions, and is time-consuming and labor-intensive. Semi-automatic packaging machines can usually only achieve partial packaging, requiring manual intervention and cannot achieve fully automated packaging. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an intelligent packaging machine for sheet materials. This intelligent packaging machine can automatically convey sheet materials forward, and while conveying, it can package and encapsulate the sheet materials with a film, and at the same time quickly clean up the excess material generated during the packaging process.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a smart packaging machine for sheet metal, comprising: One rack; A sheet metal conveyor, wherein the sheet metal conveyor is mounted on a frame; Two side sealing mechanisms are symmetrically arranged on both sides of the plate conveyor. Each side sealing mechanism includes a first side sealing frame and a second side sealing frame. A pressing component and a heat sealing component are fixed on both the first side sealing frame and the second side sealing frame. Two liftable waste material conveyors are also symmetrically arranged on both sides of the sheet material conveyor, and film spreading components are fixedly connected to the waste material conveyors; Two cutting blade assemblies are mounted between two heat sealing blocks of a heat sealing assembly.

[0005] Furthermore, both the sheet material conveyor and the waste material conveyor are belt conveyors, and the width of the waste material conveyor is one-fifth to one-quarter of the width of the sheet material conveyor.

[0006] Furthermore, transverse guide rails are fixed on the front and rear sides of the frame, and the side sealing mechanism is slidably connected to the transverse guide rails via a moving block. The two side sealing mechanisms are driven to move by an opposing drive device.

[0007] Furthermore, the pressing assembly includes pressing cylinders, with a first pressing plate and a second pressing plate respectively fixed on the cylinder rods of the two pressing cylinders located on the left side of the frame and the two pressing cylinders located on the right side of the frame; the heat sealing assembly includes heat sealing cylinders, with a linear slide rail fixed on the cylinder rod of the heat sealing cylinders, and a first heat sealing structure and a second heat sealing structure fixed at both ends of the linear slide rails via connecting plates, and a film cutting knife fixed on the sliding block of the linear slide rails.

[0008] Furthermore, both the first and second pressure plates are fixed with air blowing nozzles, which are inclined toward the plate conveyor.

[0009] Furthermore, the opposing drive device includes a first mounting plate and a second mounting plate fixed to the front and rear sides of the frame. A rotating shaft is rotatably connected between the first mounting plate and the second mounting plate. A drive gear is fixed in the middle of the rotating shaft, and end gears are fixed at both ends of the rotating shaft. A first drive motor is fixed on the frame. The first drive motor drives the rotating shaft to rotate. The end gears at both ends of the rotating shaft drive the first horizontal rack and the second horizontal rack below the two side sealing mechanisms to move in opposite directions.

[0010] Furthermore, a first vertical rack assembly and a second vertical rack assembly are fixed below the waste material conveyor, and a second drive motor is fixed on the left and right sides of the frame, respectively. The second drive motor drives two half-shafts to rotate, and the two half-shafts mesh with the first vertical rack assembly and the second vertical rack assembly through gears.

[0011] Furthermore, the conveyor belt of the waste material conveyor is provided with multiple pusher plates at even intervals.

[0012] Furthermore, the film spreading assembly includes a connecting beam fixed on the waste material conveyor. A film spreading rack and a film spreading guide rail are fixed on the left and right sides of the connecting beam, respectively. Two servo motors are slidably connected to the film spreading guide rails on the left and right sides of the connecting beam through brackets. The two servo motors are meshed with the film spreading racks on the left and right sides of the connecting beam through gears on their motor shafts, respectively. A rotary cylinder is also fixed on the bracket of each servo motor, and a film spreading arm is fixed on the cylinder rod of the rotary cylinder.

[0013] Furthermore, a first synchronous rack and a second synchronous rack are connected to the first side seal and the second side seal via a connecting seat. A synchronous shaft is connected between the two connecting seats via a bearing seat. A first synchronous gear and a second synchronous gear are fixed on the synchronous shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This intelligent packaging machine can automatically convey the board forward, and while conveying, it can package the board with film, and quickly clean up the excess material generated during the packaging process. 2. Since the side sealing mechanism is slidably connected to the transverse guide rail by a moving block and driven by a counter-driving device, it can be used for the packaging of plates of different widths, and has a wider range of applications. 3. By using the blowing nozzle, the air blown out during the forward movement of the board can cause the film to adhere to the board, making the board more tightly wrapped and the film less prone to damage.

[0016] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1-3 As shown in the figure, an embodiment of the present invention proposes a smart packaging machine for sheet metal, comprising: One rack 1; A sheet material conveyor 2 is mounted on a frame 1; Two side sealing mechanisms are symmetrically arranged on both sides of the plate conveyor 2. The side sealing mechanism includes a first side sealing frame 3 and a second side sealing frame 4. A pressing component 5 and a heat sealing component 6 are fixed on the first side sealing frame 3 and the second side sealing frame 4. Two liftable waste material conveyors 35 are also symmetrically arranged on both sides of the sheet material conveyor 2, and a film spreading assembly 7 is fixedly connected to the waste material conveyor 35. Two film cutting knife assemblies are installed between two heat sealing blocks 8 of the heat sealing assembly 6.

[0018] The process of using this invention is as follows: First, the board is connected to the board conveyor 2. Before the board is connected to the board conveyor 2, the previous process covers the front and rear ends of the board with a film. At this time, the film is open on the left and right sides of the board. The board conveyor 2 drives the board forward. During the movement, the board moves to the middle of the board conveyor 2. Then, the pressing component 5 on the side sealing mechanism is activated to press the board tightly. Then, the residual material conveyor 35 moves upward. At this time, the film spreading component 7 makes the film spread out and prevents it from rolling inward. Finally, the heat sealing component 6 heat seals the film on both sides of the board. After the heat sealing is completed, the film is cut by the film cutting component. After the film is cut, the residual material conveyor 35, the pressing component 5 and the heat sealing component 6 are all reset. The board conveyor 2 transports the sealed board forward, and the residual material conveyor 35 transports the cut film forward, and finally discharges it.

[0019] Furthermore, both the sheet material conveyor 2 and the waste material conveyor 35 are belt conveyors, and the width of the waste material conveyor 35 is one-fifth to one-quarter of the width of the sheet material conveyor 2. Specifically, both the sheet material conveyor 2 and the waste material conveyor 35 of the present invention are belt conveyors. Since the width of the cut film is relatively small, the width of the waste material conveyor 35 only needs to be about one-quarter of the width of the sheet material conveyor 2.

[0020] Furthermore, transverse guide rails 9 are fixed to the front and rear sides of the frame 1. The side sealing mechanism is slidably connected to the transverse guide rails 9 via a moving block. The two side sealing mechanisms are driven to move by an opposing drive device. Specifically, by fixing transverse guide rails 9 to both the front and rear sides of the frame 1, and slidably connecting the side sealing mechanism to the transverse guide rails 9 via a moving block, the two side sealing mechanisms can be driven to move towards each other by the opposing drive device. This allows for adjustment of the distance between the waste material conveyor 35 and the plate conveyor 2, enabling the conveying of plates of different widths.

[0021] Furthermore, the pressing assembly 5 includes pressing cylinders 10, with a first pressing plate 11 and a second pressing plate 12 fixed to the cylinder rods of the two pressing cylinders 10 located on the left side of the frame 1 and the two pressing cylinders located on the right side of the frame 1, respectively; the heat sealing assembly 6 includes a heat sealing cylinder, with a linear slide rail fixed to the cylinder rod of the heat sealing cylinder, and a first heat sealing structure 13 and a second heat sealing structure 14 fixed to both ends of the linear slide rail via connecting plates, and a film cutting knife 15 fixed to the sliding block of the linear slide rail. Specifically, the pressing assembly 5 of the present invention is a pressing cylinder 10, with the first pressing plate 11 and the second pressing plate 12 connected to the pressing cylinder 10 pressing both sides of the sheet material together. After the sheet material is pressed together, the first heat sealing structure 13 and the second heat sealing structure 14 on the heat sealing cylinder heat seal the upper film and the lower film on the left and right sides of the sheet material. The heat sealing structure is a mature structure (such as a heating wire and a heat sealing strip), which will not be described in detail here.

[0022] Furthermore, air nozzles 16 are fixed on both the first pressure plate 11 and the second pressure plate 12, and the air nozzles 16 are inclined toward the sheet conveyor 2. Specifically, the present invention has air nozzles 16 fixed on both the first pressure plate 11 and the second pressure plate 12, and the air nozzles 16 are inclined toward the sheet conveyor 2. When inclined, they blow the space between the upper and lower edges of the film side, so that the upper and lower edges are flattened, making the heat sealing process smoother and flatter. At the same time, the film spreading assembly can limit the position of the film when the air nozzle blows the film, preventing it from rolling inward.

[0023] Furthermore, the opposing drive device includes a first mounting plate 17 and a second mounting plate 18 fixed to the front and rear sides of the frame 1. A rotating shaft 36 is rotatably connected between the first mounting plate 17 and the second mounting plate 18. A drive gear is fixed in the middle of the rotating shaft 36, and end gears are fixed at both ends of the rotating shaft. A first drive motor is fixed on the frame. The first drive motor drives the rotating shaft 36 to rotate. The end gears at both ends of the rotating shaft 36 drive the first horizontal rack 19 and the second horizontal rack 20 below the two side sealing mechanisms to move in opposite directions. Specifically, the opposing drive device includes two mounting plates, and a first drive motor is installed between the mounting plates. The first drive motor drives the first horizontal rack 19 and the second horizontal rack 20 on the side sealing frame to move in opposite directions, thereby enabling the two side sealing frames to move in opposite directions.

[0024] Furthermore, a first vertical rack assembly 21 and a second vertical rack assembly 22 are fixed below the waste material conveyor 35, respectively. Second drive motors 23 are fixed to the left and right sides of the frame 1, respectively. The second drive motors 23 drive two half-shafts 24 to rotate, and the two half-shafts 24 mesh with the first vertical rack assembly 21 and the second vertical rack assembly 22 via gears. Specifically, the waste material conveyor 35 of the present invention moves towards each other via the first vertical rack assembly 21 and the second vertical rack assembly 22, and the two vertical rack assemblies are driven upwards by the second drive motor 23.

[0025] Furthermore, the belt of the waste material conveyor 35 is provided with multiple pusher plates 25 at even intervals. Specifically, the multiple pusher plates 25 on the belt of the waste material conveyor 35 facilitate pushing the cut film and allowing it to be discharged quickly.

[0026] Furthermore, the film spreading assembly 7 includes a connecting beam 26 fixed on the waste material conveyor 35. The left and right sides of the connecting beam 26 are each fixed with a film spreading rack 27 and a film spreading guide rail 28. Two servo motors 29 are slidably connected to the film spreading guide rails 28 on the left and right sides of the connecting beam 26 through brackets. The two servo motors 29 are respectively meshed with the film spreading racks 27 on the left and right sides of the connecting beam 26 through gears on their motor shafts. A rotary cylinder 30 is also fixed on the bracket of each servo motor 29. A film spreading arm 31 is fixed on the cylinder rod of the rotary cylinder 30. Specifically, during the film spreading process, after the servo motor 29 is started, its gear meshes with the film spreading rack 27 on the connecting beam 26, thereby driving the rotary cylinder 30 to move. Since the film spreading arm 31 is fixed on the cylinder rod of the rotary cylinder 30, it can drive the film spreading arm 31 to rotate and move, thereby limiting the film during the rising process of the residual material conveyor 35, so that it will not be blown inward by the airflow.

[0027] Furthermore, a first synchronous rack 32 and a second synchronous rack 33 are connected to the first side sealing frame 3 and the second side sealing frame 4 respectively via a connecting seat. A synchronous shaft 34 is connected between the two connecting seats via a bearing seat. A first synchronous gear and a second synchronous gear are fixed on the synchronous shaft 34. The first synchronous gear and the second synchronous gear mesh with the first synchronous rack 32 and the second synchronous rack 33 respectively. Specifically, in order to enable the pressing cylinders 10 on the first side sealing frame 3 and the second side sealing frame 4 to lift and lower simultaneously, thereby achieving stable downward movement of the first pressure plate 11 and the second pressure plate 12, the two side sealing frames are connected to synchronous racks via two connecting seats. The two synchronous racks mesh with the two synchronous gears on the synchronous shaft 34. Correspondingly, to achieve stable downward movement of the hot pressing assembly, a third synchronous rack 37 and a fourth synchronous rack 38 are also connected to the first side sealing frame 3 and the second side sealing frame 4. The third synchronous rack and the fourth synchronous rack also lift and lower together via the synchronous shaft 34, thereby ensuring stable downward movement of both ends of the hot pressing assembly.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
