Description

Technical Field

[0001] This utility model relates to the technical field of plastic granule feeding devices, and in particular to a plastic granule mixing and feeding device. Background Technology

[0002] Plastic products are a general term for household and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Compared to metals, stone, and wood, plastic products have advantages such as low cost and high plasticity, and are widely used in the national economy. The plastics industry holds an extremely important position in the world today, and the production of plastic products has developed rapidly worldwide for many years, with widespread applications.

[0003] Existing mixing devices use stirring rods to agitate plastic granules, allowing various types of plastic granules to be mixed in a mixing tank before processing. However, the existing stirring shaft is fixed in position during mixing, which results in a small mixing range, low mixing efficiency, and poor mixing effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a plastic particle mixing and feeding device with a compact structure that can circulate and stir multiple plastic particles evenly.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a mixing tank, a feeding seat disposed below the mixing tank for pouring materials, a lifting component disposed in the middle of the mixing tank for moving plastic granules to the upper part, and a mixing component disposed in the lifting component for pushing and stirring the plastic granules. The bottom of the mixing tank has two feeding ports for plastic granules to enter. A mixing plate is formed in the middle of the mixing tank. The mixing plate and the bottom of the mixing tank form a storage space for temporary storage of plastic granules. The mixing plate is provided with a discharge channel and a circulation port. The outlet end of the discharge channel extends out of the mixing tank. The circulation port is connected to the storage space. An adjustment component for adjusting the opening and closing of the discharge channel and the circulation port is fixedly connected to the lower end of the mixing plate.

[0006] Furthermore, the feeding seat is symmetrically provided with two feeding slots, and a baffle plate is formed between the two feeding slots to separate the plastic particles. Each feeding slot is provided with a feeding slope that gradually slopes from the outside to the inside.

[0007] Furthermore, the lifting assembly includes a mounting frame, a lifting pipe, a lifting drive device, and a lifting screw. The mounting frame is fixedly connected to the upper part of the mixing tank. A limiting plate is formed in the middle of the mounting frame. The lifting pipe is disposed in the middle of the limiting plate. The lifting drive device is fixedly connected to the middle of the mounting frame. The lifting screw is disposed at the movable end of the lifting drive device and is disposed inside the lifting pipe. The bottom of the lifting pipe has a lifting inlet that corresponds to and cooperates with the corresponding inlet. The top of the lifting pipe has two lifting outlets for throwing out plastic particles.

[0008] Furthermore, a receiving tray for evenly distributing plastic particles is formed in the middle of the lifting pipe, and a discharge plate is formed in each lifting outlet.

[0009] Furthermore, the mixing assembly includes a connecting frame, a mixing drive device, a drive wheel, a transmission wheel, and two mixing rods. The connecting frame is fixedly connected to the limiting plate, the mixing drive device is fixedly connected to the connecting frame, the drive wheel is connected to the movable end of the mixing drive device, the transmission wheel is rotatably connected to the outer wall of the lifting pipe, and each mixing rod is correspondingly arranged on one side of the transmission wheel.

[0010] Furthermore, the mixing rod is provided with a mixing pusher and several mixing fins. The mixing pusher is located at one end of the mixing rod and slides with the bottom of the mixing plate. Several mixing fins are equally spaced on one side of the mixing pusher.

[0011] Furthermore, the bottom of the mixing plate is formed with a groove that connects to the discharge channel and the circulation port. The adjustment assembly includes a fixed frame, an adjustment drive device, and an adjustment plate. The fixed frame is fixedly connected to the lower surface of the mixing plate. The adjustment drive device is disposed on the fixed frame. A push block is provided at the movable end of the adjustment drive device. The adjustment plate is slidably connected to the groove. The adjustment plate is formed with an extension rod. The extension rod and the push block are driven by a connecting plate.

[0012] Furthermore, a discharge pipe is formed at the bottom of the mixing tank, and a sealing plate is slidably connected to the lower end of the discharge pipe.

[0013] The beneficial effects of this utility model are as follows: Because this utility model adopts an adjustable discharge channel and circulation port structure, the plastic granules are continuously lifted and mixed internally through the circulation port before being fully mixed. The circulation process is simple and effective. Combined with the receiving tray set in the middle of the lifting pipe for evenly distributing the plastic granules, the incoming plastic granules are evenly mixed, improving stirring efficiency. The mixing rod is equipped with a mixing pusher and several mixing fins, both of which are designed to gradually rise from left to right, facilitating the pushing and stirring of the plastic granules at the bottom to the upper layer of the accumulated granules for further uniform mixing. The overall structure is simple and easy to use.

The mixing rod 45 is equipped with a mixing pusher 451 and several mixing fins 452. Both the mixing pusher 451 and the mixing fins 452 are designed to gradually rise from left to right, facilitating the pushing and mixing of plastic granules at the bottom to the upper layer of accumulated granules for further uniform mixing. The overall structure is simple and easy to use. With the adjustment component 5, the discharge and circulation mixing of plastic granules can be completed immediately, greatly saving labor costs for workers.

[0032] The working principle of this utility model:

[0033] The feeding seat 2 is equipped with two feeding troughs 21 for pouring in plastic granules, which can simultaneously feed in multiple different types of plastic granules for mixing. Under the vibration of the raw material driving device, the plastic granules move towards the center of the feeding seat 2 and enter the storage space 13 through the feeding port 11. Under the action of gravity, they pass through the lifting inlet 36 of the lifting pipe 32 and are lifted by the rotating lifting screw 34. Different types of plastic granules located on both sides of the lifting pipe 32 are simultaneously lifted by the rotating lifting screw 34 to the top of the mixing tank 1 and thrown out. After being thrown out, they fall into the mixing plate 1. 2. The mixing component 4 rotates to mix the incoming plastic granules. When the plastic granules are not completely mixed, the discharge channel 14 is closed and the circulation port 15 is opened. The partially mixed plastic granules in the mixing plate fall back into the storage space 13. The material is then circulated and mixed until the plastic granules are completely mixed. Then the discharge channel 14 is opened to let the plastic granules flow out to the outside. The mixing tank 1 adopts an adjustable discharge channel 14 and circulation port 15 structure. Before the plastic granules are completely mixed, the internal material is continuously lifted and mixed through the circulation port 15.
