Description

Technical Field

[0001] This application relates to the field of extrusion molding technology, and in particular to a vacuum extrusion molding production line and process for inorganic materials. Background Technology

[0002] The inorganic sheet material production line includes a storage system, a mixing system, a vacuum extrusion molding system, a drying system, a cutting system, a stacking system, and a packaging system. During the production of inorganic sheet materials, the storage system feeds various raw materials into the mixing system, which thoroughly mixes them to ensure uniform mixing. The vacuum extrusion molding system heats and melts the uniformly mixed material and extrudes it into a predetermined sheet shape using a vacuum extruder. The drying system dries and shapes the formed sheet. The cutting system cuts the sheet to the required size. The stacking system stacks the cut sheets, and finally, the packaging system packages the stacked sheets.

[0003] Traditional packaging systems are typically semi-automatic, consisting of two spaced-apart roller conveyors and an unwinding device. The unwinding device is located between the two roller conveyors and has a roll of packaging film on it. As the material is transported from one roller conveyor to the other, the unwinding device wraps the packaging film from the roll of packaging film around the material, thereby packaging the material.

[0004] Regarding the aforementioned technologies, when the unwinding device wraps the packaging film around the sheet, workers need to pull the end of the packaging film on the unwinding device onto the sheet. After packaging is completed, workers need to cut the packaging film, resulting in low packaging efficiency. Summary of the Invention

[0050] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0051] This application discloses a vacuum extrusion molding production line for inorganic materials. (Refer to...) Figure 1The inorganic material vacuum extrusion molding production line includes, in sequence, a raw material storage and conveying system 10, a high-speed mixing system 11, a mixing system 12, an extrusion molding system 13, a synchronous cutting system 14, a synchronous conveying system 15, a microwave curing system 16, a secondary cutting system 17, a palletizing system 18, a packaging system 19, and a plate-standing system 20. The packaging system 19 includes a conveying device 3, an unwinding device 4, a transfer device 5, a cutting device 6, and a traction device 7. The conveying device 3 includes a first conveyor 31 and a second conveyor 32, both of which are roller conveyors arranged along the conveying direction of the sheet material. The first conveyor 31 is located on the side closer to the palletizing system 18. Both the first conveyor 31 and the second conveyor 32 have packaging gaps. The unwinding device 4 is located between the first conveyor 31 and the second conveyor 32. The transfer device 5 is located on one side of the conveying device 3, the cutting device 6 is located on the other side of the conveying device 3, and the traction device 7 is located on the side of the unwinding device 4 closest to the first conveyor 31.

[0052] During the packaging of sheet metal, multiple sheets stacked by the palletizing system 18 are conveyed from the first conveyor 31 to the unwinding device 4. When the sheet metal approaches the unwinding device 4, the transfer device 5 clamps and transfers the sheet metal to the second conveyor 32. During the transfer, the traction device 7 pulls the packaging film onto the upper surface of the sheet metal, and the unwinding device 4 wraps the packaging film around the sheet metal. When the sheet metal is about to leave the packaging range of the unwinding device 4, the cutting device 6 cuts the packaging film. The packaged sheet metal is then transferred by the transfer device 5 to the second conveyor 32, completing the packaging process. The packaging is a fully automated process, thereby improving packaging efficiency.

[0053] Specifically, refer to Figure 2 The unwinding device 4 includes an unwinding bracket 41, an unwinding ring 42, an unwinding roller 43, and an unwinding drive 44. The unwinding bracket 41 includes a support ring and a support base. The support base is welded to the bottom of the support ring. An annular groove is formed inside the support ring, and the unwinding ring 42 is embedded in the annular groove and can rotate along the annular groove. The axial direction of the unwinding ring 42 is the same as the conveying direction of the sheet material. The axial direction of the unwinding roller 43 is the same as the axial direction of the unwinding ring 42 and is fixedly connected to the unwinding ring 42. The packaging film roll is sleeved on the unwinding roller 43 and pressed against the unwinding roller 43 by a locking nut, so that the packaging film roll needs to be subjected to a certain external force to rotate. The unwinding drive 44 is located on the support base.

[0054] Reference Figure 2The unwinding drive 44 includes a drive bracket 441, a drive gear 442, a drive gear ring 443, and a drive motor 444. The drive gear ring 443 is an internal gear ring and is coaxially welded to the inner side of the unwinding ring 42. The axis of the drive gear 442 is parallel to the drive gear ring 443 and is always meshed with it. The drive bracket 441 is a vertically arranged ear plate and is located on one side of the support ring. The drive gear 442 is rotatably connected to the drive bracket 441. The drive motor 444 is a servo motor and is fixed to the side of the drive ear plate away from the support ring by bolts. The output shaft of the drive motor 444 is fixedly connected to the rotating shaft of the drive gear 442.

[0055] When the unwinding device 4 winds the packaging film onto the sheet material, the drive motor 444 drives the drive gear 442 to rotate, which causes the drive gear ring 443 to drive the unwinding ring 42 to rotate, thereby causing the unwinding roller 43 to drive the packaging film to rotate around the center of the unwinding ring 42. When the transfer device 5 drives the sheet material to pass through the middle of the unwinding ring 42, the packaging film continues to be wound on the sheet material, thereby realizing the packaging of the sheet material.

[0056] Reference Figure 3 The transfer device 5 includes a transfer slide rail 51, a transfer bracket 52, a transfer clamping seat 53, a first transfer clamping plate 54, and a second transfer clamping plate 55. The length direction of the transfer slide rail 51 is consistent with the conveying direction of the sheet material, and the transfer slide rail 51 is fixed to one side of the conveying device 3. The transfer bracket 52 is a rectangular frame that is closed at the top and bottom, and the transfer bracket 52 is slidably connected to the transfer slide rail 51 along the length direction of the transfer slide rail 51. The transfer clamping seat 53 is a U-shaped plate, and the transfer clamping seat 53 is slidably connected to the transfer bracket 52 in a vertical direction. The first transfer clamping plate 54 and the second transfer clamping plate 55 are both slidably connected to the transfer clamping seat 53 in a direction along the conveying direction of the sheet material, and the first transfer clamping plate 54 and the second transfer clamping plate 55 slide towards or away from each other simultaneously.

[0057] Specifically, refer to Figure 3The transfer clamping seat 53 is provided with a transfer guide rod 583 and a transfer threaded rod 584. The transfer threaded rod 584 is a bidirectional threaded rod. Both the transfer guide rod 583 and the transfer threaded rod 584 are arranged parallel to the length direction of the transfer slide rail 51. The transfer guide rod 583 is fixedly connected to the transfer clamping seat 53, and the transfer threaded rod 584 is rotatably connected to the transfer clamping seat 53. A transfer clamping motor 585 is fixed to the end of the transfer clamping seat 53. The transfer clamping motor 585 is a servo motor, and the output shaft of the transfer clamping motor 585 is fixedly connected to the transfer threaded rod 584. A first transfer slider 581 and a second transfer slider 582 are jointly mounted on the transfer guide rod 583 and the transfer threaded rod 584. Both the first transfer slider 581 and the second transfer slider 582 are slidably connected to the transfer guide rod 583 and threadedly connected to the transfer threaded rod 584. A first transfer clamping plate 54 is fixedly connected to the first transfer slider 581 via an L-shaped rod, and a second transfer clamping plate 55 is fixedly connected to the second transfer slider 582 via an L-shaped rod. When transferring the sheet material, the transfer clamping motor 585 drives the transfer threaded rod 584 to rotate, causing the first transfer clamping plate 54 and the second transfer clamping plate 55 to move closer to each other, thereby clamping the side of the sheet material and facilitating its transfer.

[0058] Reference Figure 3 A limit block 521 is welded to the bottom of the transfer slide rail 51. A limit groove is provided on the transfer slide rail 51, and the limit block 521 is slidably disposed within the limit groove. A threaded rod is rotatably connected within the limit groove, passing through the limit block 521. The limit block 521 and the threaded rod are threadedly connected. A transfer sliding motor 56, a servo motor, is provided at the end of the transfer slide rail 51. The output end of the transfer sliding motor 56 is fixedly connected to the threaded rod. When the transfer sliding motor 56 rotates, the threaded rod rotates, thereby driving the limit block 521 to move, which in turn causes the transfer bracket 52 to drive the transfer clamping seat 53 to move.

[0059] Reference Figure 3 The bottom of the transfer clamp 53 is provided with multiple guide rods to improve the stability of the transfer clamp 53 when sliding. The transfer bracket 52 is provided with a lifting drive 57 inside. The lifting drive 57 is a cylinder or a hydraulic cylinder. In this embodiment, the lifting drive 57 is a cylinder. The movable end of the lifting drive 57 is welded to the bottom of the transfer clamp 53.

[0060] When packaging the sheet material, the lifting drive 57 drives the transfer clamping seat 53 to rise, and the transfer sliding motor 56 drives the transfer bracket 52 to slide close to the first conveyor 31, so that the first transfer clamping plate 54 and the second transfer clamping plate 55 are located on both sides above the sheet material. The lifting drive 57 drives the transfer clamping seat 53 to fall, so that the first transfer clamping plate 54 and the second transfer clamping plate 55 are located on both sides of the sheet material. The transfer clamping motor 585 drives the first transfer clamping plate 54 and the second transfer clamping plate 55 to move closer to each other, thereby clamping both sides of the sheet material. The transfer sliding motor 56 drives the transfer bracket 52 to slide close to the second conveyor 32, thereby transferring the sheet material above the second conveyor 32. The transfer clamping motor 585 drives the first transfer clamping plate 54 and the second transfer clamping plate 55 to move away from each other, so as to release the sheet material and convey the packaged sheet material to the upright plate system 20.

[0061] Reference Figure 4 The cutting device 6 includes a cutting bracket 61, a cutting support 62, and a cutting drive 63. The cutting bracket 61 is a plate-shaped bracket fixed to the side of the conveying device 3 away from the transfer device 5. The cutting support 62 is a rectangular plate, which is slidably connected to the cutting bracket 61, with the sliding direction perpendicular to the conveying direction of the sheet material. The cutting drive 63 is a cylinder or a hydraulic cylinder. In this embodiment, a hydraulic cylinder is used to facilitate the intermittent movement of the cutting support 62. The cutting drive 63 is fixedly connected to the cylinder body of the cutting bracket 61, and the movable end of the cutting bracket 61 is fixedly connected to the cutting support 62. Four cutting guide rods 64 are fixed on the side of the cutting support 62 near the cutting bracket 61. The cutting guide rods 64 pass through the cutting bracket 61 and are slidably connected to the cutting bracket 61.

[0062] Reference Figure 4 The cutting support 62 is provided with a cutting blade 65 and a cutting drive 66. The cutting blade 65 is a strip blade and is slidably connected to the cutting support 62. The sliding direction is perpendicular to the conveying direction of the sheet material. The cutting drive 66 is a cylinder or a hydraulic cylinder. In this embodiment, the cutting drive 66 is a miniature cylinder. The cylinder body of the cutting drive 66 is fixedly connected to the cutting support 62, and the movable end of the cutting drive 66 is fixedly connected to the cutting blade 65.

[0063] When the sheet material is about to finish being wrapped with the packaging film, that is, when the sheet material is about to leave the winding range of the unwinding device 4, the unwinding roller 43 stops at the highest point, and the cutting drive 63 drives the cutting support 62 to move closer to the unwinding roller 43. When the cutting support 62 approaches the packaging film, the cutting drive 63 stops the sliding of the cutting support 62, and the cutting drive 66 drives the cutting blade 65 to move closer to the packaging film, thereby cutting the packaging film.

[0064] Reference Figure 4The lower end of the cutting support 62 has integrally formed ear plates on both sides. A rolling roller 67 is rotatably connected between the two ear plates. The length of the rolling roller 67 is greater than the width of the packaging film, and the packaging film is located within the range of the rolling roller 67. When the cutting support 62 moves close to the unwinding roller 43, the rolling roller 67 rolls the packaging film on the upper surface of the board, so that the packaging film adheres to the upper surface of the board, thereby improving the quality of packaging.

[0065] Reference Figure 4 The upper end of the cutting support 62 has ear plates integrally formed on both sides. A guide wheel 68 is rotatably connected between the two ear plates. The guide wheel 68 is located directly above the rolling roller 67, and the length of the guide wheel 68 is the same as that of the rolling roller 67. Before the cutting blade 65 cuts the packaging film, the rolling roller 67 and the guide wheel 68 push the packaging film to a vertical position and tighten it, thereby facilitating the cutting blade 65 to cut the packaging film. The rolling roller 67 and the guide wheel 68 can keep the cutting position of the packaging film fixed each time, which is convenient for the traction device 7 to clamp the packaging film.

[0066] Reference Figure 5 and Figure 6 The traction device 7 includes a traction bracket 71, a traction clamping assembly 72, and a pressing assembly 73. The traction bracket 71 is a gantry frame and is fixed to the unwinding device 4 on the side near the first conveyor 31. The traction clamping assembly 72 and the pressing assembly 73 are both located on the traction bracket 71, and the pressing assembly 73 is located on the side of the traction clamping assembly 72 near the cutting device 6.

[0067] Specifically, refer to Figure 6The traction clamping assembly 72 includes a traction clamping bracket 721, a traction clamping seat 722, a first traction clamping plate 723, and a second traction clamping plate 724. The traction clamping bracket 721 is an L-shaped plate, and is slidably connected to the traction bracket 71. The sliding direction is along the conveying direction of the sheet material. A first drive 725 is fixed on the traction bracket 71. The first drive 725 is arranged horizontally, and its movable end is fixedly connected to the traction clamping bracket 721. A second drive 726 is fixed on the traction clamping bracket 721. The second drive 726 is arranged vertically. Both the first drive 725 and the second drive 726 are cylinders. The traction clamping seat 722 is fixedly connected to the movable end of the second drive 726, and the second drive 726 can drive the traction clamping seat 722 to move up and down. The traction clamping seat 722 is a U-shaped plate with its opening facing downwards. The first traction clamping plate 723 and the second traction clamping plate 724 are both slidably connected to the traction clamping seat 722, with the sliding direction perpendicular to the sheet material conveying direction. A traction clamping drive 727, a servo motor, is fixed to one end of the traction clamping seat 722. A guide rod is fixedly mounted on the traction clamping seat 722, and a bidirectional threaded rod is rotatably mounted on it. The guide rod and the bidirectional threaded rod are parallel to each other, and their length directions are both perpendicular to the sheet material conveying direction. The first traction clamping plate 723 and the second traction clamping plate 724 are simultaneously fitted onto the guide rod and the bidirectional threaded rod, and are slidably connected to the guide rod and threadedly connected to the bidirectional threaded rod. The movable end of the traction clamping drive 727 is fixedly connected to the bidirectional threaded rod. The second traction clamping plate 724 is located on the side of the first traction clamping plate 723 closest to the cutting device 6. When the bidirectional threaded rod rotates, the first traction clamping plate 723 and the second traction clamping plate 724 move closer to or further away from each other.

[0068] Before the cutting blade 65 cuts the packaging film, the rolling roller 67 and the guide roller 68 push the packaging film to a vertical position (see reference). Figure 7 The first drive 725 pushes the traction clamping bracket 721 to move closer to the vertical packaging film, so that the first traction clamping plate 723 and the second traction clamping plate 724 are respectively located on both sides of the vertical packaging film. The traction clamping drive 727 drives the bidirectional threaded rod to rotate, so that the first traction clamping plate 723 and the second traction clamping plate 724 move closer to each other to clamp the packaging film in the vertical state. The clamping position is close to the guide wheel 68. Then, the cutting blade 65 descends and cuts the packaging film under the drive 66. The transfer device 5 transfers the packaged board to the second conveyor 32 and clamps another batch of board below the unwinding roller 43. The second drive 726 drives the traction clamping seat 722 to move downward, so that the packaging film located below the first traction clamping plate 723 is pulled to the upper surface of the board, thereby realizing the traction of the packaging film.

[0069] Reference Figure 7A push plate 7231 is provided on the first traction clamping plate 723. The push plate 7231 is welded to the bottom of the first traction clamping plate 723. The push plate 7231 is an L-shaped plate. The end face of the push plate 7231 near the second traction clamping plate 724 protrudes from the first traction clamping plate 723.

[0070] When the first traction clamping plate 723 and the second traction clamping plate 724 clamp the packaging film, the push plate 7231 causes the packaging film located below the first traction clamping plate 723 to deflect closer to the second traction clamping plate 724, causing the packaging film below the first traction clamping plate 723 to gradually shift towards the cutting device 6, closer to the upper surface of the sheet material (see reference). Figure 8 This facilitates the pressing component 73 pressing the packaging film onto the upper surface of the board.

[0071] Reference Figure 6 The clamping assembly 73 includes a clamping bracket 731, a clamping plate 732, a third drive 733, and a fourth drive 734. Both the clamping bracket 731 and the clamping plate 732 are L-shaped plates. The clamping bracket 731 is slidably connected to the traction bracket 71, and the sliding direction is along the conveying direction of the sheet material. Both the third drive 733 and the fourth drive 734 are cylinders. The cylinder body of the third drive 733 is fixedly mounted on the traction bracket 71, and the movable end of the third drive 733 is fixedly connected to the clamping bracket 731. The cylinder body of the fourth drive 734 is fixedly mounted on the top of the clamping bracket 731, and the movable end of the fourth drive 734 is fixedly connected to the top of the clamping plate 732.

[0072] Reference Figure 8 When the packaging film below the first traction clamping plate 723 approaches the upper surface of the sheet material and gradually shifts towards the cutting device 6, the third drive 733 drives the pressing bracket 731 to move closer to the unwinding roller 43. When the pressing plate 732 is above the packaging film to be pressed, the fourth drive 734 drives the pressing plate to descend, so that the pressing plate 732 presses the packaging film onto the upper surface of the sheet material. At this time, the first drive 725 drives the traction clamping bracket 721 to move away from the unwinding roller 43, so that the first traction clamping plate 723 and the second traction clamping plate 724 make way for the winding of the packaging film. The second drive 726 drives... The traction clamping seat 722 is raised to facilitate the next traction of the packaging film. The unwinding roller 43 drives the packaging film roll to rotate around the sheet material once, pressing the end of the packaging film between another layer of packaging film and the sheet material. At this time, the third drive 733 drives the pressing bracket 731 away from the unwinding roller 43, causing the pressing plate 732 to be pulled away from the packaging film. The transfer device 5 clamps the sheet material and moves it closer to the second conveyor 32. The unwinding roller 43 continues to drive the packaging film roll to rotate around the sheet material, thereby realizing the packaging of the sheet material. Subsequently, cutting is performed, and the end of the packaging film is pulled to a new batch of sheet material, repeating the above process. The continuous fully automatic packaging process can significantly improve packaging efficiency.

[0073] In this embodiment, the packaging film is a PE stretch film, which is self-adhesive. It is a single-sided adhesive plastic film that can be stretched and tightly wrapped around backpack items. The self-adhesive does not adhere to the surface of the packaged items, but only exists between the film and the film.

[0074] This application also discloses a vacuum extrusion molding process for inorganic materials. (Refer to...) Figure 9 The inorganic material vacuum extrusion molding production process, based on the aforementioned inorganic material vacuum extrusion molding production line, includes the following steps:

[0075] S1. Raw material transportation: Raw materials are transported through the raw material storage and transportation system 10.

[0076] S2. Stirring: The high-speed stirring system 11 stirs the raw materials conveyed by the raw material storage and conveying system to initially mix the various raw materials.

[0077] S3, mixing: The mixing system 12 kneads and mixes the materials conveyed by the high-speed mixing system to make the materials evenly mixed.

[0078] S4. Extrusion molding: The uniformly mixed material is extruded into a predetermined sheet shape through the extrusion molding system 13.

[0079] S5. Initial cutting: The extruded sheet is cut into the required pre-processing size using the synchronous cutting system 14.

[0080] S6. Microwave drying and curing: The board material is transferred to the microwave curing system 16 through the synchronous conveying system 15. The microwave curing system 16 performs microwave drying on the board material to set its shape.

[0081] S7. Secondary cutting: The dried and shaped sheet material is cut into the final size through the secondary cutting system 17.

[0082] S8, stacking: multiple cut sheet materials are stacked using the stacking system 18;

[0083] S9. Packaging: The packaging system 19 is used to package multiple stacked boards together.

[0084] S10, Erecting the board: The erecting system 20 stands the packaged board upright, making it easier to transfer the board.

[0085] The implementation principle of the inorganic material vacuum extrusion molding production line and production process in this application embodiment is as follows: The first conveyor 31 transports multiple stacked sheets to one side of the unwinding device 4. The transfer device 5 clamps the sheets, and the traction device 7 pulls the packaging film on the unwinding device 4 to the upper surface of the sheets. The transfer device 5 gradually transfers the sheets to the second conveyor 32. The unwinding device 4 continuously winds the packaging film onto the sheets. When the packaging film on the sheets is wound close to the edge, the traction device 7 clamps the packaging film, the cutting device 6 cuts the packaging film, and the traction device 7 transfers the packaged sheets to the second conveyor 32. Another batch of sheets is clamped to one side of the unwinding device 4. The above process is repeated to achieve fully automated packaging and improve packaging efficiency.
