DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0031] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0032] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.
[0033] like Figure 1 and Figure 2 As shown, a bag turning and discharging device of a bag unpacking machine includes a frame 1, on which an upper conveying mechanism 2, a lower conveying mechanism 3 and a roller bag clearing mechanism 4 are arranged in parallel from top to bottom. The lower conveying mechanism is located directly below the upper conveying mechanism, and the conveying directions of the two are opposite. A guide frame 5 is obliquely arranged on one side of the output end of the upper conveying mechanism, and the lower end of the guide frame is located below the output end of the upper conveying mechanism and above the input end of the lower conveying mechanism. A guide cylinder 6 is connected between the output end of the lower conveying mechanism and the bag inlet of the roller bag clearing mechanism. The roller bag clearing mechanism includes a roller 401 rotatably connected to the frame, a V-shaped guide plate 402 and a roller driving mechanism for driving the roller to rotate. The V-shaped guide plate is inverted above the roller, combined with Figure 9As shown, the lower ends of both sides of the V-shaped material guide plate are connected with side baffles 409, and each side baffle is an integral structure with the V-shaped material guide plate to prevent the material leaked during the bag turning process from entering the drum. The bag inlet 7 is provided at one end of the drum, and the bag outlet 8 is provided at the other end of the drum. In actual use, the present invention has a cutting mechanism for unpacking the packaging bags above the input end of the upper conveying mechanism, and a hopper with an open top (not shown in the figure) is installed at the bottom of the drum bag clearing mechanism. The cutting mechanism first cuts and unpacks the packaging bags, and the unpacked packaging bags are first horizontally conveyed by the upper conveying mechanism. When they move to the output end of the upper conveying mechanism, one end of the packaging bag falls downward and flips onto the guide frame, and gradually slides to the upper end of the lower conveying mechanism. During the flipping process of the packaging bag, most of the material leaks out and slides downward into the hopper at the bottom through the V-shaped guide plate. The remaining material remains in the packaging bag and enters the drum through the guide drum. The inner wall of the drum is provided with spiral blades (not shown in the figure), forming a stirring cage conveying structure. This structure is a mature technology of existing material conveying equipment and will not be described in detail. During the rolling conveying process of the drum, the remaining material falls into the hopper and the packaging bag is discharged from the bag outlet. A protective cover 15 is provided on the outer side of the bag outlet of the drum. The lower end of the protective cover is an open structure to facilitate the centralized recovery of the packaging bags.
[0034] like Figure 2 、 Figure 3 and Figure 5 As shown, the guide frame includes a crossbeam 501 and at least two parallel guide rods 502 connected to the crossbeam at intervals and arranged obliquely. The crossbeam is connected to the higher end of each guide rod. The length direction of the crossbeam remains parallel to the width direction of the upper conveying mechanism and the lower conveying mechanism. The guide frame plays a transition role and transfers the packaging bags to the lower conveying mechanism. The frame is also rotatably connected to a roller 9 parallel to the crossbeam. The roller is coaxially provided with guide wheels 10 matching the number of guide rods. The guide wheels and the guide rods are alternately spaced. One end of the roller is connected to a bag turning motor 11 that drives it to rotate. The outer edge of each guide wheel is provided with at least two protrusions 1001 distributed in a circumferential array. Each protrusion is an integral structure with the guide wheel to improve its connection strength. When the bag turning motor works, it drives the roller and multiple guide wheels to rotate. The guide wheels can provide power for the packaging bags, prompting them to be transferred to the lower conveying mechanism, thereby improving the bag turning efficiency and the material discharge efficiency. In this embodiment, both the upper conveyor mechanism 2 and the lower conveyor mechanism 3 utilize belt conveyors with identical structures, including a conveyor belt, a driving roller, and a driven roller. The driving roller and the driven roller are located at either end of the conveyor belt and are rotatably connected to the frame. This structure is conventional and will not be described in detail here. To reduce equipment manufacturing costs, the driving rollers of both the upper and lower conveyor mechanisms are powered by bag-turning motors, which utilize a sprocket chain transmission mechanism to drive the driving rollers and rollers of both conveyor mechanisms.
[0035] Combine Figure 4 As shown, a bag blocking assembly is provided on the frame, and the bag blocking assembly spans above the upper conveying mechanism. The bag blocking assembly includes an upper cross bar 12 and a lower cross bar 13 arranged in parallel above and below. At least two support rods 14 are evenly spaced between the upper cross bar and the lower cross bar. A gap is left between the lower cross bar and the top of the upper conveying mechanism. When the utility model is actually used, the cutting mechanism installed above the input end of the upper conveying mechanism can preferably realize a horizontal cutting method to divide the packaging bag into two parts, an upper part and an lower part. The bag blocking assembly can first block the upper part of the packaging bag. After the lower part of the material and the packaging bag pass through the bottom of the lower cross bar, the upper part of the packaging bag and part of the material fall onto the upper conveying mechanism and continue to be conveyed, which can improve the material discharge efficiency and reduce the amount of residual material in the packaging bag.
[0036] like Figures 6 to 8 As shown, both ends of the drum are provided with convex rings 406 along the circumferential direction. Each convex ring is in transmission cooperation with support wheels 407 provided on both sides thereof. Each pair of support wheels forms a group and is symmetrically distributed on both sides of one end of the drum to support the drum. Each support wheel is rotatably connected to the frame. The frame is also rotatably connected to two pressure wheels 408, which are respectively in transmission cooperation with the two convex rings. The pressure wheels are located on top of the convex rings. The two support wheels at each end of the drum are arranged in a triangular shape with the pressure wheels to ensure the stability of their rotation. The drum drive mechanism includes a drum motor 403, a drive gear 404, and a ring gear 405. The drum motor is connected to the drive gear, which meshes with the ring gear. The ring gear is provided on the outside of one end of the drum along the circumferential direction of the drum. The drum motor provides power to the drive gear, which drives the ring gear and the drum to rotate.
[0037] The working principle of this utility model is as follows:
[0038] like Figures 1 to 9 As shown, in actual use of the present invention, a cutting mechanism for unpacking the packaging bags is provided above the input end of the upper conveyor mechanism 2, and a hopper with an open top is installed below the drum bag clearing mechanism 4. The cutting mechanism first cuts and breaks the packaging bags. The unpacked packaging bags are first conveyed horizontally by the upper conveyor mechanism 2. When they move to the output end of the upper conveyor mechanism 2, one end of the packaging bag falls downward and flips onto the guide frame 5, gradually sliding to the top of the lower conveyor mechanism 3. During the flipping process of the packaging bag, most of the material leaks out and slides downward into the hopper through the V-shaped guide plate 402. A small amount of material, along with the unpacked packaging bag, slides from the guide frame 5 to the lower conveyor mechanism 3 under the rotation of the guide wheel 10, and then enters the interior of the drum 401 through the guide drum 6. The drum motor 403 drives the drum 401 to rotate, causing the packaging bag to flip inside, shaking out the remaining material into the hopper, and finally the packaging bag is discharged from the bag outlet 8.
[0039] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included in the present invention.
