Description

Technical Field

[0001] This utility model relates to the field of material sorting technology, and in particular to a bidirectional rejection machine. Background Technology

[0002] In modern industrial production lines, especially in the food, pharmaceutical, and daily necessities packaging sectors, product quality inspection has become a core component. Currently widely used equipment such as metal detectors and weight detectors must be linked with dedicated rejection machines: when the detection equipment identifies a non-conforming product, it triggers the subsequent rejection machine to remove it from the production line.

[0003] While this traditional one-to-one configuration model can achieve basic sorting functions, it has revealed significant drawbacks in practical applications. With the increasing sophistication of production line inspection processes, the parallel deployment of multiple inspection devices has become the norm. Each inspection device requires an independent rejection machine, which not only multiplies equipment procurement costs but also results in a severe waste of space resources in the production line layout. This is especially problematic for small and medium-sized enterprises with limited factory space; dense arrays of rejection machines can squeeze production line space and even force companies to abandon some inspection processes due to insufficient space, compelling them to compromise between quality control and production capacity. Furthermore, dispersed rejection machines cause defective products to be scattered across different nodes of the production line, increasing the complexity of waste recycling. Utility Model Content

[0004] In view of the above situation and in order to make up for the shortcomings of the existing technology, the purpose of this utility model is to provide a bidirectional rejection machine, which effectively solves the problems of large space occupation and high cost of existing rejection machines.

[0005] The technical solution is as follows: This utility model includes an outer support frame, inside which is an inner support frame. The inner support frame has rotating columns on the front and rear sides, which are rotatable along the left and right axes. Multiple bearing wheels are coaxially arranged on the rotating columns and evenly distributed in the left and right directions. A mesh conveyor belt is provided between the bearing wheels on the front and rear sides. A protective plate is provided on the outer support frame above the mesh conveyor belt. A bidirectional rejection plate that can move left and right is provided inside the protective plate. Inclined placement plates are provided at the left and right ends of the mesh conveyor belt, and multiple rollers are rotatably connected to the placement plates.

[0006] Preferably, the bidirectional rejection plate is slidably connected to the protective plate, and a pneumatic push rod is provided on the outer support frame, with the free end of the pneumatic push rod fixedly connected to the bidirectional rejection plate.

[0007] Preferably, the protective plate is provided with sliding columns on both the front and rear sides, and the sliding columns are slidably connected to the bidirectional rejection plate via linear bearings.

[0008] Preferably, the rotating column is rotatably connected to the inner support frame, and the inner support frame on the rear side is provided with a servo motor for the left and right axes. The free end of the servo motor and the right end of the rotating column on the rear side are respectively provided with sprockets, and the two sprockets are connected by a chain belt.

[0009] Preferably, the outer support frame is equipped with an air source processor, which is connected to the pneumatic push rod via a connecting pipe.

[0010] Preferably, the lower ends of the inner support frame and the outer support frame are respectively provided with support legs.

[0011] Preferably, the left and right ends of the front rotating column are respectively provided with movable blocks that are slidably connected to the inner support frame, and the inner support frame is rotatably connected with adjusting studs that are threadedly connected to the movable blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are: it can realize the dual-station synchronous sorting function on a single device, which not only completely solves the problem of space occupation caused by the parallel placement of traditional rejection machines in multi-inspection equipment scenarios, but also reduces equipment procurement and maintenance costs. Furthermore, the precise lateral displacement of its bidirectional rejection plate under the guidance of the sliding column and linear bearing, combined with the stable thrust of the air source processor, ensures that defective products are instantly pushed away from the main conveyor line and slide into the roller temporary storage area along the inclined placement plate.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the implementations of the base model disclosed below.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Depend on Figures 1 to 4 The system includes an outer support frame 1, an inner support frame 2 inside the outer support frame 1, rotating columns 3 on the front and rear sides of the inner support frame 2, and multiple load-bearing wheels 4 evenly distributed in the left and right directions on the rotating columns 3. A mesh conveyor belt 5 is provided between the load-bearing wheels 4 on the front and rear sides. A protective plate 6 is provided on the outer support frame 1 above the mesh conveyor belt 5. A bidirectional rejection plate 7 that can move left and right is provided inside the protective plate 6. Inclined placement plates 8 are provided at the left and right ends of the mesh conveyor belt 5. Multiple rollers 9 are rotatably connected to the placement plates 8.

[0022] To facilitate the left and right movement of the bidirectional rejection plate 7, the bidirectional rejection plate 7 is slidably connected to the protective plate 6, and the outer support frame 1 is provided with a pneumatic push rod 10, the free end of which is fixedly connected to the bidirectional rejection plate 7.

[0023] To facilitate the movement of the bidirectional rejection plate 7, the protective plate 6 is provided with sliding columns 11 on the front and rear sides respectively, and the sliding columns 11 are slidably connected to the bidirectional rejection plate 7 via linear bearings 12.

[0024] In order to make the rotating column 3 rotate, the rotating column 3 is rotatably connected to the inner support frame 2. The inner support frame 2 on the rear side is provided with a servo motor 13 with left and right axes. The free end of the servo motor 13 and the right end of the rotating column 3 on the rear side are respectively provided with sprockets 14, and the two sprockets 14 are connected by a chain belt 15.

[0025] In order to purify the gas, the outer support frame 1 is equipped with a gas source processor 16, which is connected to the pneumatic push rod 10 via a connecting pipe 17.

[0026] For ease of support, the lower ends of the inner support frame 2 and the outer support frame 1 are respectively provided with support legs 18.

[0027] To facilitate the adjustment of the progress of the two rotating columns, the left and right ends of the front rotating column 3 are respectively provided with movable blocks 19 that are slidably connected to the inner support frame 2, and the inner support frame 2 is rotatably connected with adjusting studs 20 that are threadedly connected to the movable blocks 19.

[0028] When this utility model is in use, after the product is qualified by the front-end testing equipment, it continues to move along the left and right direction with the mesh conveyor belt 5: the servo motor 13 drives the rear rotating column 3 to rotate through the sprocket 14 and the chain belt 15, which drives the bearing wheel 4 to rotate synchronously, so that the mesh conveyor belt 5, which is tensioned between the front and rear rotating columns 3, smoothly transmits the product. At this time, the bidirectional rejection plate 7 remains in the center of the protective plate 6 in a standby state. After the qualified product passes through the working area below the protective plate 6, it flows to the next process. When the front-end metal detector or weight detector identifies a defective product on the left, it sends a rejection command to the control system. The compressed air purified by the air source processor 16 drives the pneumatic push rod 10 to retract through the connecting pipe 17, pulling the bidirectional rejection plate 7 to move quickly to the left along the slide column 11 and linear bearing 12, pushing the defective product laterally away from the mesh conveyor belt 5, so that it slides into the temporary storage area of ​​the roller 9 along the inclined placement plate 8 at the left end. When the detection equipment on the right sends a rejection signal, the pneumatic push rod 10 extends in the opposite direction to push the bidirectional rejection plate 7 to the right, and similarly pushes the defective product on the right into the corresponding temporary storage area of ​​the roller 9. During the process, the displacement of the moving block 19 of the front rotating column 3 is controlled by adjusting the stud 20, which can correct the tension of the mesh conveyor belt 5 in real time to ensure the stability of operation. Meanwhile, the defective products temporarily stored on both sides of the rollers 9 are collected manually at regular intervals, realizing the single machine synchronous processing of dual-station rejection tasks.

[0029] Compared with the prior art, the beneficial effects of this utility model are as follows: the bidirectional rejection plate, bearing wheel, and mesh conveyor belt can realize the dual-station synchronous sorting function on a single machine. This not only completely solves the problem of space occupation caused by the parallel placement of traditional rejection machines in multi-inspection equipment scenarios, but also reduces equipment procurement and maintenance costs. Furthermore, the precise lateral displacement of the bidirectional rejection plate under the guidance of the sliding column and linear bearing, combined with the stable thrust of the air source processor, ensures that defective products are instantly pushed away from the main conveyor line and slide into the roller storage area along the inclined placement plate. This structure is simple, novel in concept, convenient to use, and highly practical.

[0030] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.

[0031] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this 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.
