Description

Technical Field

[0001] This utility model relates to the field of plastic sheet production technology, and in particular to a centralized feeding device for a plastic sheet production line. Background Technology

[0002] Plastic sheets are a common type of engineering plastic product, usually in the form of thin sheets. They have high strength, corrosion resistance, wear resistance, and excellent electrical insulation properties. The production of plastic sheets requires centralized material supply to maintain centralized production.

[0003] In the production of plastic sheets and plates, it is often necessary to use a centralized feeding system to accurately deliver raw materials to each workstation on the production line. However, existing feeding devices are mostly single-feeding devices, which are prone to uneven material delivery and blockage problems, making it impossible to continuously deliver materials and thus failing to meet the high-efficiency requirements of the production line. To address this issue, we propose a centralized feeding device for plastic sheet and plate production lines. Utility Model Content

[0004] The purpose of this invention is to provide a centralized feeding device for a plastic sheet production line to solve the problems mentioned in the background art.

[0007] In a further embodiment, a rubber pad is provided on the outer surface of each eccentric wheel, and each rubber pad is located at the end of the eccentric wheel with a larger radius.

[0008] In a further embodiment, a reinforcing plate is rotatably connected to the other end of the rotating shaft, and the top of the reinforcing plate is connected to the bottom surface of the frame plate.

[0011] In a further embodiment, a connecting plate is installed on both the bottom surface and the upper surface of the support platform, and the other end of each connecting plate is connected to the outer surface of the lifting cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, through the coordination of a hopper, lifting cylinder, conveying pipe, motor, rotating rod, discharge pipe, outlet pipe, solenoid valve, and spiral blades, uses the conveying pipe to transport materials from inside the hopper to the lifting cylinder. When the motor is working, the rotating rod drives the spiral blades to rotate, and the material is lifted upwards into the discharge pipe.

Through the coordination of a motor, rotating shaft, and eccentric wheel, the motor drives the eccentric wheel to rotate, and the eccentric wheel repeatedly strikes the discharge pipe, thereby preventing blockage.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[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.

[0020] Please see Figure 1-3 In this utility model, a centralized feeding device for a plastic sheet production line includes a hopper 1. A lifting cylinder 2 is provided on the right side of the hopper 1. The outer surface of the lifting cylinder 2 and the bottom end of the hopper 1 are connected by a conveying pipe 11. The hopper 1 can hold materials, and the materials will enter the lifting cylinder 2 through the conveying pipe 11.

[0021] A support platform 13 is fixedly connected to the outer surface of the silo 1. A ring of supporting legs 12 is fixedly connected to the bottom surface of the support platform 13. By cooperating with the supporting platform 13 and the supporting legs 12, the silo 1 can be stably supported and kept in a stable state.

[0022] A connecting plate 10 is installed on both the bottom and upper surfaces of the support platform 13. The other end of each connecting plate 10 is connected to the outer surface of the lifting cylinder 2. The connecting plate 10 can be used to connect the lifting cylinder 2 and the support platform 13, ensuring the stability of the lifting cylinder 2.

[0023] A motor 3 is installed on the upper surface of the lifting cylinder 2. A rotating rod 18 is installed at the output end of the motor 3. The bottom end of the rotating rod 18 is rotatably connected to the inner bottom wall of the lifting cylinder 2. A spiral blade 19 is fixedly connected to the outer surface of the rotating rod 18. A discharge pipe 6 is fixedly connected to the outer surface of the top end of the lifting cylinder 2. The operation of the motor 3 can drive the rotating rod 18 to rotate, and the spiral blade 19 will also rotate synchronously, thereby lifting the material upward and the material will enter the discharge pipe 6.

[0024] A set of discharge pipes 9 are fixedly connected to the outer surface of the discharge pipe 6. Each discharge pipe 9 is connected to a solenoid valve 8 on its outer surface. By controlling the opening and closing of the solenoid valves 8 at different positions, the material can be discharged from different discharge pipes 9, thereby enabling feeding operations on different production lines.

[0025] A frame plate 4 is fixedly connected to the upper surface of the motor 3 and the outer surface of the lifting cylinder 2. A motor 5 is installed on the bottom surface of the frame plate 4. A rotating shaft 16 is fixedly connected to the output end of the motor 5. A set of equidistant eccentric wheels 14 are fixedly connected to the outer surface of the rotating shaft 16. When the motor 5 works, it will drive the rotating shaft 16 to rotate. The eccentric wheels 14 will repeatedly strike the discharge pipe 6, thereby allowing the material inside the discharge pipe 6 to flow and avoiding blockage.

[0026] Each eccentric wheel 14 has a rubber pad 15 on its outer surface. Each rubber pad 15 is located at the end of the eccentric wheel 14 with the larger radius. The rubber pads 15 can protect the discharge pipe 6 and prevent damage to the discharge pipe 6.

[0027] A set of discharge pipes 9 are fixedly connected to a support plate 7 on their outer surfaces. The left end of the support plate 7 is connected to the outer surface of the lifting cylinder 2. The support plate 7 can be used to connect the discharge pipes 9 and the lifting cylinder 2, thus providing support for the discharge pipes 9 and enhancing their stability.

[0028] The other end of the rotating shaft 16 is rotatably connected to a reinforcing plate 17. The top of the reinforcing plate 17 is connected to the bottom surface of the frame plate 4. The reinforcing plate 17 can be used to support the other end of the rotating shaft 16, thereby ensuring the stable rotation of the rotating shaft 16.

[0029] The working principle of this utility model is as follows: When in use, the material is poured into the hopper 1, and then the motor 3 is started. The motor 3 will drive the rotating rod 18 and the spiral blade 19 to rotate synchronously. The material inside the hopper 1 will enter the lifting cylinder 2 through the conveying pipe 11. As the spiral blade 19 rotates, the material will gradually rise. When the material reaches the top of the lifting cylinder 2, it will enter the discharge pipe 6. Then, according to the different feeding positions on the production line, the corresponding solenoid valve 8 is opened. The material inside the discharge pipe 6 will be discharged to the corresponding production line along the corresponding discharge pipe 9. At the same time, the motor 5 can be started. The rotating shaft 16 will drive the eccentric wheel 14 to repeatedly knock on the discharge pipe 6, thereby avoiding blockage inside the discharge pipe 6, thus achieving the effect of centralized material supply.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
