Description

Technical Field

[0001] This utility model relates to the field of plastic pellet dispensing technology, and in particular to a plastic pellet dispensing device. Background Technology

[0002] In some industrial production processes, material distributors are needed to allocate materials to different equipment. In the field of plastic granule distribution technology, existing distribution devices, such as the rotary distributor for automatic plastic granule distribution described in application number CN202221120070.7, work by using a motor to drive a distribution tube to rotate to different discharge pipe positions, with an encoder for precise positioning. Specifically, the motor drives the distribution tube to rotate circumferentially through a reducer, connecting shaft, and mounting plate. Once the distribution tube aligns with the target discharge pipe, it stops, and the plastic granules are discharged from the end of the distribution tube, completing the distribution. However, this device has the following drawbacks: First, it has high energy consumption. Due to the large size and weight of the distribution tube, the motor consumes a significant amount of energy to drive its rotation, especially with frequent start-stop cycles. Second, it has low distribution efficiency. The rotation speed of the distribution tube is limited by its own weight and size, resulting in a slow rotation process, prolonging the distribution cycle, and reducing overall distribution efficiency. Therefore, this application proposes a plastic granule distribution device to address the shortcomings of the existing technology. Utility Model Content

[0003] The main objective of this invention is to provide a plastic granule dispensing device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A plastic granule dispensing device includes a connector, which consists of a main housing and connecting pipes. The connecting pipes are fixedly installed at the upper end of the main housing. Several dispensing pipes are fixedly inserted into the lower part of the connector. Each dispensing pipe consists of an upper pipe and a lower pipe, with the lower pipe located below the upper pipe. A connecting bracket is fixedly sleeved on the upper and lower pipes. The connecting bracket consists of a connecting sleeve and a U-shaped bracket. Two connecting sleeves are symmetrically fixedly installed at one end of the U-shaped bracket. An opening and closing assembly is fixedly installed on each of the lower pipes. The opening and closing assembly consists of a fixed base plate, a connecting plate, a rotating plate, a reduction motor, and a laser sensor. The rotating plate is located above the fixed base plate. The connecting plate is fixedly installed on the outer wall of the fixed base plate. The reduction motor is fixedly installed at the lower end of the fixed base plate, with its output axis passing upward through the fixed base plate and fixedly connected to the rotating plate. The laser sensor is fixedly installed at the upper end of the rotating plate.

[0006] Preferably, the lower side wall of the main housing on the connector has a plurality of insertion holes arranged in a ring.

[0007] Preferably, the upper pipe of the material distribution pipe is fixedly inserted into the insertion hole opened on the lower side wall of the main housing.

[0008] Preferably, the two connecting sleeves on the connecting bracket are fixedly sleeved on the upper pipe and the lower pipe, respectively.

[0009] Preferably, the fixed base plate of the opening and closing component has a plurality of mounting holes in a ring shape, and the fixed base plate is fixedly sleeved on a plurality of lower pipes through the mounting holes.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By setting up a material distribution device consisting of connectors, distribution pipes, connecting brackets, and opening / closing components, efficient and energy-saving material distribution of plastic granules is achieved. Specifically, the fixed material distribution pipe design avoids the energy consumption problem of traditional rotary material distribution pipes.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a plastic granule dispensing device includes a connector 1, which consists of a main housing 5 and a connecting pipe 6. The connecting pipe 6 is fixedly installed on the upper end of the main housing 5. Several dispensing pipes 2 are fixedly inserted into the lower part of the connector 1. Each dispensing pipe 2 consists of an upper pipe 7 and a lower pipe 8. The lower pipe 8 is located below the upper pipe 7. A connecting bracket 3 is fixedly sleeved on the upper pipe 7 and the lower pipe 8. The connecting bracket 3 consists of a connecting sleeve 9 and a U-shaped bracket 10. There are two connecting sleeves 9, which are symmetrically fixedly installed on one end of the U-shaped bracket 10. An opening and closing assembly 4 is fixedly installed on each of the several lower pipes 8. The opening and closing assembly 4 consists of a fixed base plate 11, a connecting plate 12, and a rotating... The device consists of a rotating plate 14, a geared motor 16, and a laser sensor 17. The rotating plate 14 is located above the fixed base plate 11. The connecting plate 12 is fixedly installed on the outer wall of the fixed base plate 11. The geared motor 16 is fixedly installed at the lower end of the fixed base plate 11. The output axis of the geared motor 16 passes through the fixed base plate 11 and is fixedly connected to the rotating plate 14. The laser sensor 17 is fixedly installed at the upper end of the rotating plate 14. In use, the material distribution device is first installed in the designated position through the connecting plate 12 to ensure that the device is stable. The connecting pipe 6 is connected to the pipe of the upstream feeding equipment to receive plastic granular materials. The lower pipe 8 is connected to the pipes of different downstream target equipment to realize the diversion of materials. During operation, plastic granules enter the main housing 5 through the connecting pipe 6 and then flow into the upper pipe 7 of each distribution pipe 2. The opening and closing assembly 4 drives the rotating plate 14 to rotate via the reduction motor 16. When the discharge hole 15 on the rotating plate 14 is coaxial with the upper pipe 7 and lower pipe 8 of a certain distribution pipe 2, the plastic granules flow out through the lower pipe 8 of that distribution pipe 2, completing the distribution. The laser sensor 17 is used to detect the position of the rotating plate 14 to ensure accurate switching of the distribution path. The connecting bracket 3 fixes the upper pipe 7 and lower pipe 8 through the connecting sleeve 9 to maintain the stability of the distribution pipe 2. This device, through the design of the fixed distribution pipe 2 and the lightweight rotating plate 14, only requires controlling the rotation of the rotating plate 14 to switch the distribution path, avoiding the high energy consumption problem of traditional rotating distribution pipes, while improving the distribution efficiency.

[0020] Specifically, the lower side wall of the main housing 5 on the connector 1 has several insertion holes in a ring shape. The upper pipe 7 on the distribution pipe 2 is fixedly inserted into the insertion holes on the lower side wall of the main housing 5. The two connecting sleeves 9 on the connecting bracket 3 are fixedly sleeved on the upper pipe 7 and the lower pipe 8 respectively. To ensure sealing, the gap between the upper pipe 7 and the lower pipe 8 should be smaller than the particle size of the plastic particles to prevent the plastic particles from leaking out from the gap.

[0021] Specifically, the fixed base plate 11 of the opening and closing assembly 4 has several mounting holes 13 arranged in a ring. The fixed base plate 11 is fixedly sleeved on several lower pipes 8 through the mounting holes 13. Several connecting plates 12 are arranged in a ring on the outer wall of the fixed base plate 11. The rotating plate 14 of the opening and closing assembly 4 is rotatably installed between the upper pipe 7 and the lower pipe 8. The rotating plate 14 has a material feeding hole 15. The thickness of the rotating plate 14 is less than the gap between the upper pipe 7 and the lower pipe 8, thereby ensuring that the rotating plate 14 can rotate smoothly. The diameter of the material feeding hole 15 is the same as the inner diameter of the upper pipe 7 and the lower pipe 8, thereby ensuring that the plastic particles pass through quickly and without obstruction. This material dispensing device achieves precise material dispensing through the coordinated work of the laser sensor 17 and the reduction motor 16. The laser sensor 17 monitors the positioning marks on the edge of the rotating plate 14 in real time and feeds back the position signal to the control system. As the rotating plate 14 rotates, the system controls the start and stop of the reduction motor 16 based on sensor data: when it rotates rapidly to near the target position, it automatically switches to low-speed mode, ultimately ensuring that the material feeding hole 15 is precisely aligned with the target lower pipe 8. This photoelectric closed-loop control method achieves high positioning accuracy, ensuring both material feeding speed and accuracy.

[0022] Finally, by setting up a material distribution device consisting of connector 1, material distribution pipe 2, connecting bracket 3, and opening / closing assembly 4, efficient and energy-saving material distribution of plastic granules is achieved. Specifically, the design of fixed material distribution pipe 2 avoids the energy consumption problem of traditional rotating material distribution pipe. The opening and closing control can be completed by driving the lightweight rotating plate 14 to rotate through the geared motor 16, which significantly reduces the driving load of the geared motor 16 and has obvious energy-saving effect. At the same time, the lightweight rotating plate 14 rotates faster under the drive of the geared motor 16, so that the material distribution path can be switched more quickly, thereby improving the material distribution efficiency.

[0023] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
