Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a waste film collection device and a bending machine system. Background Technology

[0002] In practical industrial applications, bending machines are mainly used to bend and shape sheet metal (such as stainless steel, aluminum, and galvanized steel). These sheet metals typically have a protective film (commonly a plastic film made of PE / PVC / OPP) attached to their surface during manufacturing or transportation. This film prevents the sheet metal from being scratched, oxidized, or contaminated during handling, storage, or processing. This protective film must be removed before or after bending to ensure the quality of subsequent processes (such as welding, painting, and assembly) and the appearance of the finished product.

[0003] However, in existing bending machine systems, the removed waste film is prone to scattering and is difficult to collect centrally.

[0004] Therefore, there is an urgent need for a new waste film collection device and bending machine system. Utility Model Content

[0027] Please refer to Figures 1 to 3This application provides a waste film collection device 10 for collecting waste film removed by a film-tearing device. The waste film collection device 10 includes at least one brush 11, a first collection member 12, a second collection member 15, and a vacuum generating mechanism 16. The brush 11 has bristles 111 arranged along a first direction Z along its length, and the bristles 111 are spaced apart along a second direction X. The first collection member 12 is disposed on one side of the brush 11 along the first direction Z. The inlet of the second collection member 15 communicates with the outlet of the first collection member 12. The vacuum generating mechanism 16 is disposed between the first collection member 12 and the second collection member 15, and is used to create a negative pressure airflow between the first collection member 12 and the second collection member 15. The first collection member 12 has a notch 121 on one side along a third direction Y, through which the waste film extends into the brush 11 along the third direction Y, and falls into the second collection member 15 via the first collection member 12. Among them, the first direction Z, the second direction X, and the third direction Y are perpendicular to each other.

[0028] To better illustrate this application, let the first direction Z be the vertical direction. Then, the first direction Z and the second direction X are two parallel directions in the horizontal direction. A Cartesian coordinate system can be established with the first direction Z as the Z-axis, the second direction X as the X-axis, and the third direction Y as the Y-axis. The first direction Z represents the height of the waste membrane device, the second direction X represents the length, and the third direction Y represents the width. The third direction Y is also the direction of waste membrane inflow.

[0029] The waste membrane collection device 10 provided in this application embodiment allows the waste membrane to extend horizontally through the notch 121 of the first collection member 12 into the vertically arranged brush 11. The waste membrane is brushed by the brush 11 and peeled off under the elastic force of the brush bristles 111. Under the guidance of gravity and the negative pressure of the vacuum generating mechanism 16, it falls into the second collection member 15 after passing through the first collection member 12, thus achieving efficient and continuous waste membrane collection without scattering.

[0030] Specifically, the bottom outlet of the first collector 12 is connected to the top inlet of the second collector 15 via a connecting channel; the vacuum generating mechanism 16 is connected to the connecting channel. The vacuum generating mechanism 16 can be connected to an external air passage, and can generate negative pressure by drawing air outwards.

[0031] Based on the aforementioned embodiment, the brush 11 is detachably connected to the first collecting member 12 via the first connecting member 13, and the brush 11 is detachably connected to the first connecting member 13. This facilitates quick replacement or cleaning of the brush 11 after wear, avoids downtime for overall machine maintenance, and improves equipment availability and maintenance efficiency.

[0032] In one feasible implementation, the brush bristles 111 of the brush 11 are provided with a brush body base 112 on the side away from the first collector 12 along the first direction Z, and the brush body base 112 is fixedly connected to the first collector 12 through a first connector 13. The bristles 111 of the brush 11 are arranged at intervals along the second direction X, and multiple rows of bristles 111 are provided along the third direction Y to increase the brushing or stroking effect.

[0033] In one feasible implementation, the first connecting member 13 includes a first part 131, a second part 132, and a third part 133 connected in a U-shape. The second part 132 extends along a second direction X. The first part 131 and the third part 133 are respectively connected to the two ends of the second part 132 in the second direction X. Adjustment slots 134 are respectively formed on the first part 131 and the third part 133, the length direction of which is parallel to the third direction Y. The first connecting member 13 is fixedly connected to the first collecting member 12 by fasteners, the fasteners passing through the adjustment slots 134 along a first direction Z and screwed onto the first collecting member 12. The adjustment slots 134 are oblong through slots. When the fasteners are loosened, the first connecting member 13 can be adjusted in position relative to the first collecting member 12 along the third direction Y. By providing waist-shaped adjustment slots 134 extending along the third direction Y on both sides of the first connector 13, and in conjunction with vertical fasteners, the position of the brush 11 assembly in the waste film entry direction (third direction Y) can be finely adjusted. This design can accommodate the stroke deviation or film width difference of different models of film tearing claws, ensuring that the waste film is always accurately inserted into the gap of the brush bristles 111, improving the cleaning success rate and equipment compatibility.

[0034] Based on the aforementioned embodiment, the brush 11 is detachably connected to the first connecting member 13 via a second connecting member 14. The brush body base 112 of the brush 11 is disposed between the first connecting member 13 and the second connecting member 14 along the third direction Y. The second connecting member 14 is U-shaped. Both ends of the second connecting member 14 abut against the first connecting member 13 along the second direction X. A plurality of threaded holes 144 are formed in the middle of the second connecting member 14. A plurality of set screws pass through the threaded holes 144 to press the brush body base 112 against the second part 132, thus fixing the brush body base 112 to the first connecting member 13. Further, the second connecting member 14 includes a first segment 141, a second segment 142, and a third segment 143 connected sequentially in a U-shape, wherein the second segment 142 extends along the second direction X, and the first segment 141 and the third segment 143 are respectively connected to the two ends of the second segment 142 in the second direction X. A plurality of threaded holes 144 are disposed at the second end. A gap is formed between the U-shaped second connector 14 and the first connector 13. Several set screws pass through the threaded hole 144 to press the base of the brush 11 against the first connector 13. This ensures the stability of the brush 11 during the high-speed waste film peeling process and supports quick assembly and disassembly—the brush 11 assembly can be pulled out simply by loosening the set screws, significantly improving maintenance convenience.

[0035] Based on the aforementioned embodiment, the first portion 131 and the third portion 133 of the first connector 13 further extend one end towards the second connector 14 along the third direction Y. Alternatively, the first connector 13 is H-shaped. The first end and the third end of the second connector 14 abut against the first portion 131 and the third portion 133, respectively. The two ends of the brush base 112 along the second direction X abut against the side of the first portion 131 and the third portion 133 that are close to each other. Thus, the first portion 131 and the third portion 133 can also limit the movement of the brush 11 in the second direction X, preventing the brush 11 from moving during brushing and improving the stability of the waste film collection process.

[0036] In one feasible implementation, the waist-shaped through groove is a countersunk waist-shaped groove. This retains the third-party Y-position adjustment function while embedding the fastener head inside the connector, preventing the protruding structure from interfering with surrounding moving parts, thus improving the overall safety and space utilization of the equipment.

[0037] In one feasible implementation, the first collecting element 12 is a conical hopper. The conical hopper has an inclined inner wall and a narrow bottom, which facilitates the smooth sliding of the waste membrane to the outlet under the combined action of gravity and negative pressure, preventing accumulation and blockage, and ensuring that the waste membrane is efficiently introduced into the second collecting element 15.

[0038] Based on the aforementioned embodiments, in order to facilitate the fixed connection between the conical hopper and the brush 11, a hopper cover plate 122 can also be provided on the first collecting member 12. The hopper cover plate 122 is located above the conical hopper, and the hopper cover plate 122 can reduce the upward opening of the conical hopper and reduce the risk of film flying.

[0039] In one feasible implementation, the second collection element 15 is a nylon bag with several micropores. Using a nylon filter bag with micropores as the second collection element 15 allows airflow to pass through under vacuum negative pressure while trapping waste membrane, achieving gas-solid separation; at the same time, the nylon material is flexible and wear-resistant, making it easy to remove for cleaning or replacement periodically, reducing operating costs.

[0040] In one feasible implementation, the waste film collection device 10 includes a plurality of brushes 11, with the first collection element 12 corresponding to each brush 11. In this embodiment, the waste film collection device 10 includes four brushes 11. Further, this embodiment includes four second collection elements 15 and four vacuum generating mechanisms 16. By setting multiple brushes 11 and corresponding first collection elements 12, waste film from multiple film-tearing stations can be processed simultaneously, suitable for multi-head robotic arms or parallel production lines. This also facilitates equipment maintenance.

[0041] In one feasible implementation, to facilitate the fixed installation of multiple brushes 11, multiple first collection elements 12, multiple second collection elements 15 and multiple vacuum generating mechanisms 16, the waste film collection device 10 further includes a base plate 17, with multiple first collection elements 12 fixedly connected to the base plate 17. The base plate 17 can then be connected to other devices or equipment in the system for installation and layout optimization.

[0042] In one feasible implementation, the waste membrane collection device 10 includes a second collection element 15 and a vacuum generating mechanism 16 (not shown in the figure). That is, the brushes 11 are separately arranged, but only one vacuum generating mechanism 16 and second collection element are provided. This can save costs and space and facilitate the collection of waste membrane.

[0043] Accordingly, this application also provides a bending machine system, which includes any of the aforementioned waste film collection devices 10, as well as a bending device and a film-tearing device. In this bending machine system, the film material on the surface of the component to be bent is first removed by the film-tearing device, the waste film is fed into the waste film collection device 10, and then the component to be bent is bent by the bending device. The bending machine system provided in this application, using the aforementioned waste film collection device 10, can achieve efficient and continuous waste film collection without scattering.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
