Abstract

The application discloses a packaging all-in-one machine for BMC material production and relates to the technical field of BMC material packaging. The packaging all-in-one machine comprises a control box, a first mechanical hand for clamping an inner bag is fixedly connected to one side of the control box, a second mechanical hand for clamping an outer bag is arranged on the lower side of the first mechanical hand, a removing mechanism for removing fiber groups on the surface of BMC material is arranged on one side of the control box, a cutting mechanism for cutting BMC material is arranged on the lower side of the removing mechanism, and a bag sealing mechanism for sealing the inner bag is arranged on the lower side of the cutting mechanism. The first electric rotating table drives the BMC material for primary packaging to rotate above the outer bag. The inner bag is not only filled into the inner part of the outer bag, but also turned over, so that the too-narrow end is first inserted into the inner part of the outer bag. Due to the change of gravity, the BMC material at the wide end of the inner bag flows to the narrow end, and gradually becomes narrow, so that the inner bag filled with BMC material is conveniently filled into the inner part of the outer bag.

Description

Technical Field

[0001] This invention relates to the field of BMC material packaging technology, specifically to an integrated packaging machine for BMC material production. Background Technology

[0002] BMC (Bipolar Mixed Fiberglass) is a thermosetting composite material made from unsaturated polyester resin, chopped glass fibers, fillers, and various additives. It is widely used in the automotive, electronics, and construction industries, and is typically used to manufacture high-performance parts.

[0003] Existing BMC materials are typically packaged in transparent plastic bags. The equipment used to produce BMC materials extrudes the material, and workers place plastic bags underneath to catch the falling BMC material. When the plastic bag is full, a cutting blade above automatically cuts the connected BMC material. Workers then seal the transparent plastic bag containing the BMC material, thus achieving sealing and barrier. To prevent the single-layer plastic bag from being worn or torn by the edges of the BMC material during transportation, a woven bag is placed over the transparent plastic bag for double protection.

[0004] The manual process of filling inner bags, receiving materials, sealing, and then filling outer bags is cumbersome and time-consuming, much slower than the production cycle of the extruder. This becomes a bottleneck in the entire production line, limiting overall capacity. Furthermore, due to uneven mixing of raw materials or fiber aggregation during transportation, fiber clumps may adhere to the surface of the BMC material during the extrusion, cutting, and downward falling packaging stage. If these fiber clumps are not removed from the BMC material in time before packaging, they will form a weak point in the product, failing to effectively transfer and disperse stress. This leads to a significant reduction in the tensile strength, flexural strength, and impact toughness of the product, thereby greatly reducing its mechanical strength.

[0005] Therefore, it is necessary to design an integrated packaging machine for BMC material production that features automatic double-layer bagging and intelligent fiber clump removal. Summary of the Invention

[0013] According to the above technical solution, the removal mechanism includes a second positioning plate fixedly connected to one side of the control box.

A rotating ring is slidably connected inside the circular groove. A third fixing plate is fixedly connected to the outer side of the guide plate. A motor is fixedly connected to the upper side of the third fixing plate. The output end of the motor passes through the third fixing plate and is fixedly connected to a turntable. A belt is slidably connected to the outer side of both the rotating ring and the turntable. The belt passes through the guide plate. A clamping assembly is provided on the lower side of the guide plate.

[0014] According to the above technical solution, the clamping assembly includes an L-shaped block fixedly connected to the lower side of the rotating ring. An electric push rod is fixedly connected to one side of the L-shaped block. A guide cylinder is provided on the lower side of the L-shaped block.

[0015] According to the above technical solution, the output end of the electric push rod passes through the L-shaped block and is fixedly connected to a sliding block.

Each second connecting rod is hinged to the first connecting rod, and a camera for photographing the surface of BMC material is fixedly connected to one side of the positioning post.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] 1. By controlling the rotation of the inner bag and outer bag through the first and second bagging mechanisms respectively, the BMC material is initially bagged and then bagged again in sequence, achieving the effect of automatic secondary bagging of BMC material. The initial bagging and secondary bagging are carried out simultaneously, which greatly increases the efficiency of secondary bagging of BMC material. The first electric rotary table drives the initially packaged BMC material to rotate above the outer bag. This is not only to put the inner bag into the outer bag, but also to flip the inner bag so that the narrow end is inserted into the outer bag first. Due to the change of gravity, the BMC material at the wide end of the inner bag flows to the narrow end and gradually narrows, making it easier to put the inner bag full of BMC material into the outer bag. This effectively prevents the phenomenon that the bottom of the inner bag is too wide and difficult to put into the outer bag.

[0019] 2. The clamping assembly is rotated by a motor, and the camera captures real-time images of the BMC material surface to quickly identify fiber clumps. This allows the electric push rod to extend and retract rapidly, cutting off the fiber clumps and collecting them in a waste bin. This achieves intelligent fiber clump removal with high efficiency. The extension and retraction of the electric push rod not only brings the curved cutter's slits closer together or opens them, but also allows it to move a distance closer to the BMC material before cutting, delaying the cutting process. This effectively prevents the normally placed curved cutter from getting too close to the BMC material, affecting its descent and causing accidental cutting. Moving the rod away from the BMC material before opening it delays the opening, preventing premature opening of the curved cutter and the resulting fiber clumps falling back into the falling BMC material. A single drive is sufficient for both delayed cutting and delayed opening of the curved cutter, achieving energy savings. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1-10 The present invention provides a technical solution: an integrated packaging machine for BMC material production, including a control box 1. A first robotic arm 2 for gripping an inner bag is fixedly connected to one side of the control box 1. A second robotic arm 3 for gripping an outer bag is provided below the first robotic arm 2. A removal mechanism 4 for removing fiber clumps from the surface of the BMC material is provided on one side of the control box 1. A cutting mechanism 5 for cutting the BMC material is provided below the removal mechanism 4. A sealing mechanism 6 for sealing the inner bag is provided below the cutting mechanism 5. A first bagging mechanism 7 for performing a first bagging of the BMC material is provided below the sealing mechanism 6. A second bagging mechanism 8 for performing a second bagging of the BMC material is provided below the first bagging mechanism 7. A conveyor 9 for conveying the BMC material after the second bagging is provided below the second bagging mechanism 8.

[0040] The first bag-making mechanism 7 includes a first electric rotary table 71 fixedly connected to one side of the control box 1. The rotating end of the first electric rotary table 71 is provided with a first rotating disk. Four sets of first bag-opening components 72 are evenly fixedly connected to one side of the first rotating disk. Each set of first bag-opening components 72 is provided with a support plate 73 on one side, and the support plate 73 is fixedly connected to the first rotating disk of the first electric rotary table 71.

[0041] The specific description of the above structure is as follows: The first electric rotary table 71 is used to drive the first rotating disk to rotate, thereby driving the first bag opening assembly 72 to rotate. Whenever the first robot arm 2 places an inner bag into the leftmost first bag opening assembly 72, and the first bag opening assembly 72 at the top finishes its initial bag filling and the first bag opening assembly at the bottom finishes its second bag filling, the first electric rotary table 71 drives the first rotating disk to rotate 90 degrees, rotating the placed inner bag into the bag sealing mechanism 6, and rotating the empty first bag opening assembly 72 below to the side of the first robot arm 2 to replenish the next inner bag. The support plate 73 is used to support the inner bag containing BMC material to prevent the inner bag from falling off.

[0042] The second bagging mechanism 8 includes a second electric rotary table 81 fixedly connected to one side of the control box 1. The rotating end of the second electric rotary table 81 is provided with a second rotating disk. Four sets of second bag opening components 82 are evenly fixedly connected to one side of the second rotating disk. Each second bag opening component 82 is provided with a first feeding gate 83 and a second feeding gate 84 on one side. The first feeding gate 83 and the second feeding gate 84 are hinged to the second rotating disk of the second electric rotary table 81 by torsion springs.

[0043] The specific description of the above structure is as follows: The second electric rotary table 81 is used to drive the second rotating disk to rotate, thereby driving the second bag opening assembly 82 to rotate. Whenever the second robot arm 3 places an outer bag into the leftmost second bag opening assembly 82, the second electric rotary table 81 drives the second rotating disk to rotate 90 degrees, rotating the placed outer bag to directly below the second bag opening assembly 82, and rotating the empty second bag opening assembly 82 below to the side of the second robot arm 3 to replenish the next outer bag. The first discharge gate 83 and the second discharge gate 84 are used to drop the BMC material after the second bagging is completed onto the conveyor 9 for transmission through the outer bag with the inner bag.

[0044] When the BMC clump is placed in the bag, the material will quickly sink and accumulate at the bottom of the inner bag under the influence of gravity. The lower half of the bag is stretched wide and full, while the upper half (near the bag opening) has very little material, forming a top-light and bottom-heavy structure. When trying to stuff this clump of material, which is wide at the bottom and narrow at the top and has a full bottom, into the outer bag, the huge width at the bottom will get stuck at the bag opening and make it difficult to put in. The first electric rotating table 71 drives the BMC material that was initially packaged to rotate above the outer bag. This is not only to put the inner bag into the outer bag, but also to flip the inner bag so that the narrow end is put into the outer bag first. Due to the change in gravity, the BMC material at the wide end of the inner bag flows to the narrow end and gradually narrows, making it easier to put the inner bag full of BMC material into the outer bag.

[0045] The first bag opening assembly 72 includes a double-ended cylinder 721 fixedly connected to one side of the first rotating disk. Both output ends of the double-ended cylinder 721 are fixedly connected to clamping plates 723. A first positioning plate 722 is fixedly connected to one side of the clamping plate 723. A plurality of suction nozzles 724 are evenly fixedly connected to one side of the first positioning plate 722.

[0046] The specific explanation based on the above structure is as follows: the extension and retraction of the output end of the double-ended cylinder 721 is used to drive the two clamps 723 to move closer or further away from each other, thereby driving the air intakes 724 on both sides to move closer or further away from each other, and then attaching the air intakes 724 on both sides of the inner bag or outer bag respectively.

[0047] When it is necessary to open the bag, the suction nozzle 724 draws air through the pump body, thereby sucking in the two sides of the inner or outer bag. The output end of the double-ended cylinder 721 extends, thereby driving the two suction nozzles 724 to move away from each other, thus opening the inner or outer bag.

[0048] After the secondary bagging of the BMC material is completed, the suction nozzle 724 closes, and the BMC material presses against the first discharge gate 83 and the second discharge gate 84. Since the weight of the BMC material is greater than the elastic force of the torsion spring, the first discharge gate 83 and the second discharge gate 84 are driven to rotate, thereby allowing the BMC material to pass through and pass through the lowest second bag opening assembly 82. When the output end of the double-ended cylinder 721 of the uppermost second bag opening assembly 82 extends, the output end of the double-ended cylinder 721 of the lowermost second bag opening assembly 82 extends simultaneously, thereby facilitating the passage of the secondary bagged BMC material.

[0049] The sealing mechanism 6 includes two first fixing plates 62 fixedly connected to one side of the control box 1. A first hydraulic cylinder 61 is fixedly connected to one side of the two first fixing plates 62, and a first guide column 63 is fixedly connected to the other side of the two first fixing plates 62. The output end of the first hydraulic cylinder 61 passes through the first fixing plate 62 and is fixedly connected to a first sliding plate 64. The first sliding plate 64 is slidably connected to the first guide column 63. A heat sealing block 65 is fixedly connected to one side of each first sliding plate 64.

[0050] The specific explanation based on the above structure is as follows: the top of the inner bag is located between the two heat-sealing blocks 65. After the initial packaging of the BMC material is completed, the output end of the first hydraulic cylinder 61 extends and drives the two heat-sealing blocks 65 to approach the two sides of the inner bag respectively. The heat-sealing blocks 65 are embedded with electric heating tubes, which convert electrical energy into heat energy to heat the upper two sides of the inner bag, thereby completing the sealing of the inner bag.

[0051] The cutting mechanism 5 includes two second fixing plates 51 fixedly connected to one side of the control box 1. A second hydraulic cylinder 52 is fixedly connected to one side of the two second fixing plates 51, and a second guide column 54 is fixedly connected to the other side of the two second fixing plates 51. The output end of the second hydraulic cylinder 52 passes through the second fixing plate 51 and is fixedly connected to a second sliding plate 53. The second sliding plate 53 is slidably connected to the second guide column 54. A cutter 55 is fixedly connected to one side of each second sliding plate 53.

[0052] The specific explanation of the above structure is as follows: the cutting mechanism 5 will be activated once every certain period of time, that is, when the BMC material inside the inner bag is almost full, the output end of the second hydraulic cylinder 52 extends and drives the two cutters 55 to move closer to each other, thereby cutting the connected BMC material. During the cutting, the feeding device is turned off, and after the cutting is completed, the feeding device is restarted.

[0053] The removal mechanism 4 includes a second positioning plate 41 fixedly connected to one side of the control box 1. A guide plate 42 is fixedly connected inside the second positioning plate 41. A circular groove 47 is provided inside the lower side of the guide plate 42. A rotating ring 46 is slidably connected inside the circular groove 47. A third fixing plate 44 is fixedly connected to the outer side of the guide plate 42. A motor 43 is fixedly connected to the upper side of the third fixing plate 44. The output end of the motor 43 passes through the third fixing plate 44 and is fixedly connected to a turntable 49. A belt 48 is slidably connected to the outer side of both the rotating ring 46 and the turntable 49. The belt 48 passes through the guide plate 42. A clamping assembly 45 is provided on the lower side of the guide plate 42.

[0054] The specific explanation of the above structure is as follows: the guide plate 42 is used to guide the BMC material through, and the rotation of the output end of the motor 43 is used to drive the turntable 49 to rotate, thereby indirectly driving the rotating ring 46 to slide along the circular groove 47 through the belt 48, and then driving the lower clamping assembly 45 to rotate around the BMC.

[0055] The clamping assembly 45 includes an L-shaped block 451 fixedly connected to the lower side of the rotating ring 46. An electric push rod 452 is fixedly connected to one side of the L-shaped block 451. A guide cylinder 453 is provided on the lower side of the L-shaped block 451. Fixing strips 454 are fixedly connected to both sides of the L-shaped block 451. A waste box 455 is fixedly connected to the lower side of the fixing strips 454. A first limiting plate 456 and a third limiting plate 458 are fixedly connected to the upper side of the guide cylinder 453. A second limiting plate 457 is provided on one side of the first limiting plate 456 and is fixedly connected to the L-shaped block 451. A fourth limiting plate 459 is provided on one side of the third limiting plate 458 and is fixedly connected to the L-shaped block 451.

[0056] The output end of the electric push rod 452 passes through the L-shaped block 451 and is fixedly connected to a sliding block 4531. The sliding block 4531 is a square in the middle and cylindrical at both ends. The upper end of the sliding block 4531 is slidably connected to the inside of the L-shaped block 451, and the lower end of the sliding block 4531 is slidably connected to the inside of the guide cylinder 453. A second spring 4539 and a first spring 4537 are respectively provided on both sides of the lower end of the sliding block 4531. Both the second spring 4539 and the first spring 4537 are fixedly connected to the guide cylinder 453. A sliding column 4538 passes through the middle of the guide cylinder 453. The sliding column 4538 is located between the second spring 4539 and the first spring 4537. The sliding column 4538 passes through the sliding block 4531 and is fixedly connected to the sliding block 4531.

[0057] Four first connecting rods 4535 are evenly hinged to the outer side of the guide cylinder 453. One end of each first connecting rod 4535 is fixedly connected to a curved cutter 4532. One end of the sliding column 4538 is fixedly connected to a positioning column 4534. Four second connecting rods 4536 are hinged to the outer side of the positioning column 4534. Each second connecting rod 4536 is hinged to the first connecting rod 4535. A camera 4533 for photographing the surface of BMC material is fixedly connected to one side of the positioning column 4534.

[0058] The specific description of the above structure is as follows: the waste box 455 is used to put the cut-off fiber clumps, and the extension and retraction of the output end of the electric push rod 452 is used to drive the sliding block 4531 to slide along the inside of the L-shaped block 451.

[0059] The control box 1 is equipped with a judgment module and a database. The database contains identification photos of fiber clusters at different locations on the surface of BMC material.

[0060] After the camera 4533 captures an image of the BMC material surface, it converts the image into an electrical signal and sends it to the judgment module. The judgment module first compares the image with the identification photos of fiber clusters at different locations on the BMC material surface in the internal database to pre-identify whether there are fiber clusters in front of it. Based on the obtained photos of the BMC material surface, the module distinguishes the surface condition of the BMC material into surfaces with impurities and surfaces without impurities.

[0061] In the initial state, the clamping assembly 45 is in a semi-open state, and the middle of the four curved cutters 4532 can restrict the cut fiber clumps. At this time, the output end of the electric push rod 452 extends by half, and neither the second spring 4539 nor the first spring 4537 is compressed.

[0062] Please see Figure 10 At this time, the clamping assembly 45 is in the cutting state. When the judgment module determines that there are impurities on the surface of the BMC material and the BMC material needs to be cut, the output end of the electric push rod 452 starts to extend quickly, driving the sliding block 4531 to slide quickly to the left. Since the elastic force of the second spring 4539 is greater than the pressure of the sliding block 4531 on the second spring 4539, the second spring 4539 cannot be compressed temporarily. The second spring 4539 pushes the guide tube 453, and the guide tube 453 is driven to move to the left and approach the falling BMC material.

[0063] Until the first limiting plate 456 is blocked by the second limiting plate 457, the guide cylinder 453 is limited. At this time, the pressure of the sliding block 4531 on the second spring 4539 gradually increases until it exceeds the elastic force of the second spring 4539. At this time, the second spring 4539 is compressed, and the sliding column 4538 is driven to move to the left, thereby driving the second connecting rod 4536 and the first connecting rod 4535 to rotate in sequence, thereby driving the cutting edges of the four curved cutters 4532 to come closer to each other until they contact each other, and digging out the fiber clump.

[0064] As the fiber clump is excavated, the output end of the electric push rod 452 begins to retract rapidly. When the output end of the electric push rod 452 retracts to half its stroke, it is in the initial state. The second spring 4539 gradually rebounds. At this time, the four curved cutters 4532 move away from each other and open a small gap. The fiber clump is then confined in the middle of the four curved cutters 4532 and cannot fall. The output end of the electric push rod 452 continues to retract. Since the elastic force of the first spring 4537 is greater than the pressure of the sliding block 4531 on the first spring 4537, the first spring 4537 cannot be compressed temporarily.

[0065] The first spring 4537 pushes the guide cylinder 453, which is driven to move to the right and away from the falling BMC material until the third limiting plate 458 is blocked by the fourth limiting plate 459, and the guide cylinder 453 is limited. At this time, the pressure of the sliding block 4531 on the first spring 4537 gradually increases until it exceeds the elastic force of the first spring 4537. At this time, the first spring 4537 is compressed, and the sliding column 4538 is driven to move to the right, thereby driving the second connecting rod 4536 and the first connecting rod 4535 to rotate in sequence, thereby driving the cutting edges of the four curved cutters 4532 to move away from each other until they are fully opened. At this time, the fiber clump falls into the interior of the waste box 455 for collection. The output end of the electric push rod 452 extends again to half of its stroke, thereby driving the clamping assembly 45 back to its initial state.

[0066] When the judgment module determines that there are no foreign objects on the surface, the output end of motor 43 rotates, continuously driving the clamping assembly 45 to rotate around the BMC material until foreign objects are detected, at which point the output end of motor 43 will stop rotating.
