[0002] Polyethylene and polypropylene need to be sorted during the production process. Generally, bags of polyethylene and polypropylene are transported by conveyor belts, and then identified and classified by scanning equipment. Automated robotic arms then clamp the polyethylene and polypropylene separately for palletizing and stacking. However, the use and maintenance costs of automated robotic arms are high, which is a heavy burden on enterprises. If robotic arms are not used, manual palletizing is required, which is time-consuming and labor-intensive. Therefore, it is necessary to propose an automated identification, sorting, palletizing, and stacking equipment for polyethylene and polypropylene to solve the above problems. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, this utility model provides an automatic identification and sorting palletizing and stacking device for polyethylene and polypropylene, which features automatic sorting and palletizing, low operating costs, and easy maintenance and repair.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic identification and sorting palletizing and stacking device for polyethylene and polypropylene, comprising a conveyor belt, one end of which is fixedly connected to a first transmission frame, one end of which is fixedly connected to a first collection frame, a second transmission frame symmetrically arranged on one side of the first transmission frame, one end of which is fixedly connected to a second collection frame, the second collection frame being symmetrically arranged with the first collection frame, the first transmission frame comprising a fixed side plate, a fixed rod, and a roller, two fixed side plates symmetrically arranged, a fixed rod fixed to the side wall of the fixed side plate, a roller sleeved on the outer side of the fixed rod, a first stop rod fixed to one side of the first collection frame, a second stop rod fixed to the other side of the first collection frame, a spring fixed to the inner bottom surface of the first collection frame, a support plate fixed to the top of the spring, a material picking groove symmetrically arranged on the top surface of the support plate, the support plate being located between the first stop rod and the second stop rod.

[0005] As a preferred technical solution of the automatic identification and sorting palletizing and stacking equipment for polyethylene and polypropylene according to this utility model, a fixed frame is fixedly connected between the first transmission frame and the second transmission frame. The fixed frame has a rotating hole on its inner side. An arc-shaped connecting plate is fixedly connected to the lower end of the fixed frame. Baffles are symmetrically fixed on both sides of the arc-shaped connecting plate. A guide plate is movably sleeved on the outer side of the arc-shaped connecting plate.

[0006] As a preferred technical solution of the automatic identification and sorting palletizing and stacking equipment for polyethylene and polypropylene according to this utility model, one end of the guide plate is provided with a sleeve hole, and the inner wall of the sleeve hole is symmetrically fixed with second locking teeth. The top of the fixing frame is fixed with a motor, and the output end of the motor is fixed with a rotating rod. The rotating rod passes through the rotating hole, and the bottom of the rotating rod is fixed with a rotating plate. The rotating plate is located inside the arc-shaped connecting plate, and the outer wall of the rotating plate is fixed with a first locking tooth, which is located between the second locking teeth.

[0007] As a preferred technical solution of the automatic identification and sorting palletizing equipment for polyethylene and polypropylene according to this utility model, an extension rod is fixed to one side of the upper end of the fixed frame, and a scanning head is fixed to the bottom of one end of the extension rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] In use, this invention utilizes a scanning head, motor, guide plate, first transmission frame, second transmission frame, first collection frame, and second collection frame. When transporting, sorting, and stacking polyethylene and polypropylene, the raw materials are conveyed via a conveyor belt. When the raw materials reach below the scanning head, they are scanned and identified. After identification, the scanned information is processed by an external information processing device, which then controls the motor to start, causing the guide plate to rotate. The rotating guide plate guides different types of raw materials to the first or second transmission frame. The identification and sorting technology is a relatively common existing technology, so it is not described in detail here. When different types of materials enter different transmission frames, they can slide to the inside of the collection frame via the rollers of the transmission frame. After the material moves to the support plate inside the collection frame, it compresses the bottom spring, causing the material to move downwards to make room for recycling. This continues until the next material moves above the current material, at which point the spring is compressed again. The transmission frame and collection frame automatically collect and stack the materials, eliminating the need for manual stacking, saving time and labor. Compared to existing methods that use robotic arms for automatic gripping, this method has lower operating costs and is more practical. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Please see Figure 1-5This utility model provides the following technical solution: an automatic identification and sorting palletizing and stacking device for polyethylene and polypropylene, including a conveyor belt 1, which can refer to common existing conveyor belts. One end of the conveyor belt 1 is fixedly connected to a first transmission frame 6. A second transmission frame 8 is symmetrically arranged on one side of the first transmission frame 6 for conveying different types of materials. A fixing frame 2 is fixedly connected between the first transmission frame 6 and the second transmission frame 8. The fixing frame 2 is located at one end of the conveyor belt 1. An extension rod 4 is fixed to one side of the upper end of the fixing frame 2. A scanning head 5 is fixed to the bottom of one end of the extension rod 4. The scanning head 5 is located above the conveyor belt 1. The scanning head 5 is a common camera scanning device. The scanning head 5 is connected to an external computer device to realize automatic scanning and identification of different materials. The specific usage and principle can refer to the existing technology, so they are not described in detail here.

[0021] Reference Figure 2 , Figure 3 and Figure 4 As shown, specifically, the inner side of the fixed frame 2 is provided with a rotating hole 21, and the lower end of the fixed frame 2 is fixedly connected with an arc-shaped connecting plate 22. That is, the fixed frame 2 is divided into two sections and connected by the arc-shaped connecting plate 22. Baffles 24 are symmetrically fixed on both sides of the arc-shaped connecting plate 22, and a guide plate 23 is movably sleeved on the outer side of the arc-shaped connecting plate 22, which can guide the material to move along the conveyor belt 1 to the inner side of different transmission frames. One end of the guide plate 23 is provided with a sleeve hole 231, and the inner wall of the sleeve hole 231 is symmetrically fixed with two second locking teeth 232. The top of the fixed frame 2 is fixed with a motor 3, and the output end of the motor 3 is fixed with a rotating rod 31. The rotating rod 31 passes through the rotating hole 21, and the bottom of the rotating rod 31... A rotating plate 32 is fixed inside the arc-shaped connecting plate 22. The rotating plate 32 can be driven to rotate by the motor 3. A first locking tooth 33 is fixed on the outer wall of the rotating plate 32. The first locking tooth 33 is located between the second locking teeth 232. The motor 3 drives the rotating plate 32 to rotate, which can cause the guide plate 23 to rotate. By limiting the rotation space of the guide plate 23, and controlling the start and stop of the motor 3 through the external system, the guide plate 23 can be controlled to rotate and tilt to different positions after the scanning head 5 identifies the material category. For example, tilting to the right can guide the material to the second conveyor frame 8, and tilting the guide plate 23 to the right can guide the material to the first conveyor frame 6, thereby realizing the automatic identification and sorting of materials.

[0022] Reference Figure 1 and Figure 5As shown, specifically, one end of the first conveying frame 6 is fixedly connected to the first collecting frame 7, and one end of the second conveying frame 8 is fixedly connected to the second collecting frame 9. The second collecting frame 9 and the first collecting frame 7 are symmetrically arranged. The first conveying frame 6 includes a fixed side plate 61, a fixed rod 62, and a roller 63. Two fixed side plates 61 are symmetrically arranged. The side wall of the fixed side plate 61 is fixed with the fixed rod 62. The outside of the fixed rod 62 is sleeved with the roller 63. The roller 63 can rotate, and the gap between adjacent rollers 63 is small to avoid material jamming. Multiple fixed rods 62 and rollers 63 are provided. The first conveying frame 6 and the second conveying frame 8 are inclined downwards to stably guide the material to the inside of the collecting frame. A first stop bar 71 is fixed to one side of the first collecting frame 7, and the other side of the first collecting frame 7 is fixed with... A second stop bar 72, shorter than the first stop bar 71, is provided to prevent material from escaping the collection frame. A spring 73 is fixed to the inner bottom surface of the first collection frame 7, and a support plate 74 is fixed to the top of the spring 73. The support plate 74 is located between the first stop bar 71 and the second stop bar 72. After the material is guided to the support plate 74, it can compress the spring 73. By selecting a spring 73 with appropriate elasticity, one piece of material can press the spring 73 down by the distance of one piece of material, allowing the next piece of material to move stably above the current material until the collection frame is full. Through the set transmission frame and collection frame, automatic stacking of materials can be achieved without manual stacking, saving time and labor. At the same time, compared with robotic arm stacking, the operating cost is low and the practicality is strong.

[0023] Reference Figure 5 As shown, specifically, an elastic plate 64 is fixed to the side wall edge of the fixed side plate 61. The elastic plate 64 is located above the roller 63. The elastic force of the elastic plate 64 is less than the impact force of the material movement to avoid jamming the material. At the same time, the elastic plate 64 blocks the edge of the roller 63 to further prevent the material from jamming. Example 2

[0024] In another embodiment of this solution, refer to Figure 5 As shown, specifically, the top surface of the support plate 74 is symmetrically provided with material picking slots 75. There are two material picking slots 75 symmetrically provided, and the baffle does not block the material picking slots 75. After the stacking is completed, common forklift tools can be used to insert into the inside of the material picking slots 75 to remove the entire pile of materials, making material picking convenient.

[0025] The working principle and usage process of this utility model are as follows: When sorting and stacking polyethylene and polypropylene, the materials are transported by conveyor belt 1. After being transported to the area below the scanning head 5, the materials are scanned and identified, and the information is transmitted to an external control computer. At the same time, the motor 3 is started, causing the rotating rod 31 of the motor 3 to drive the rotating plate 32 to rotate. The rotating plate 32 tilts the guide plate 23. When the guide plate 23 tilts to the right, it can guide the material to the inside of the second conveying frame 8. When the guide plate 23 tilts to the left, it can guide the material to the inside of the second conveying frame 8. The material is guided to the inside of the first conveyor frame 6. After entering the inside of the first conveyor frame 6, it can slide down along the roller 63 until it slides into the top of the support plate 74 of the first collection frame 7. The material is elastically supported by the bottom spring 73, which allows the material to press the support plate 74 down to make room for the material to follow. As the material continues to slide into the inside of the collection frame, the spring 73 is continuously compressed until the collection frame is full of material. The second collection frame 9 works in the same way. Through the above structure, the material can be automatically identified, sorted and stacked. The structure is simple and the cost of use is low.

[0026] When it is necessary to remove the material inside the collection box, the entire pile of material can be removed by inserting the material chute 75 on the support plate 74 with the help of an external forklift tool.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
