Abstract
Description
Technical Field
[0001] This utility model relates to the field of PE processing equipment, and more specifically, to a PE plastic granule drying and feeding system. Background Technology
[0002] High molecular weight polymers refer to high molecular weight compounds formed by repeating bonds. They include crystalline, amorphous, oriented, and textured structures. Plastics are a type of polymer material, composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Plastics are important organic synthetic polymer materials with a wide range of applications, and are considered essential materials in modern society.
[0003] Because existing plastic pellet drying equipment cannot filter and collect plastic debris from plastic pellets during use, thus affecting the use and quality of plastic pellets, people have improved the drying efficiency and quality by opening vents in the side panels and installing scrapers and brushes inside the mixing tank. This not only filters debris but also scrapes the inner wall. For example, Chinese utility model patent with announcement number CN221549177U discloses a PE pellet drying device.
[0004] However, in actual use, it has been found that since the plastic granules are directly fed into the drying drum, the amount of material fed cannot be controlled during the feeding process. If too many plastic granules are fed in, it may cause the space inside the drying drum to become crowded, reducing the drying efficiency. How to invent a plastic granule drying feeding system to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a PE plastic granule drying and feeding system, which aims to solve the problem that excessive plastic granules may cause overcrowding in the drying drum and reduce drying efficiency.
[0006] This utility model is implemented as follows:
[0007] This utility model provides a PE plastic granule drying and feeding system, including a drying chamber and a feeding box; the feeding box is fixed on the drying chamber, and a first feeding pipe is provided on the side of the feeding box away from the drying chamber. A guide rail is provided on the drying chamber, and a second feeding pipe is slidably connected to the guide rail. A cylinder is installed on the feeding box, and the output end of the cylinder is fixedly connected to the second feeding pipe; a filter plate is provided on the first feeding pipe, and a collection frame is provided on one side of the filter plate. The collection frame is fixedly connected to the feeding box. A motor is installed on one side of the feeding box, and a spiral auger is provided inside the feeding box. One end of the spiral auger is fixedly connected to the output end of the motor. A discharge port is opened on the side of the feeding box near the drying chamber, and a baffle is provided at the discharge port. Several elastic components are connected to one side of the baffle, and the elastic components are fixed to the feeding box.
[0008] Preferably, the side of the second feed pipe away from the feed box is attached to the drying chamber, and the drying chamber has a feed inlet, with the second feed pipe corresponding to the feed inlet; this facilitates control of the amount of plastic granules fed into the drying chamber.
[0009] Preferably, the side of the first feed pipe is rotatably connected to the filter plate, and both the filter plate and the feed box are rotatably connected to connecting blocks, with springs connecting the connecting blocks; this facilitates the filtration of the fed particles.
[0010] Preferably, the feed box has a cavity on the side near the drying chamber, and the baffle is slidably connected inside the cavity, and the baffle corresponds to the discharge port; this helps to reduce particle waste.
[0011] Preferably, the elastic component consists of an elastic part and a telescopic rod, with the elastic part sleeved over the telescopic rod, and the elastic component is arranged laterally on the feed box; this saves the physical effort required for manual resetting.
[0012] Preferably, the cross-section of the guide rail is "L" shaped, and protrusions are fixed on both sides of the second feed tube, with the protrusions disposed inside the guide rail; this facilitates the improvement of the stability of the second feed tube.
[0013] The beneficial effects of this utility model are:
[0014] 1. This PE plastic granule drying and feeding system, by setting a feeding box on the drying chamber, ensures uniform feeding of plastic granules after they enter the first feeding pipe and are conveyed by a screw conveyor, preventing blockage of plastic granules inside the feeding box. A certain amount of plastic granules are then fed into the drying chamber through the second feeding pipe, which improves the control of the feeding amount during the feeding process and greatly improves the efficiency of drying plastic granules in the drying chamber. Moreover, the conveying structure is stable and reliable, which facilitates uniform feeding during the feeding process.
[0015] 2. This PE plastic granule drying and feeding system, by setting guide rails on the drying chamber and sliding baffles on the feeding box, can improve the stability of the second feeding pipe when the cylinder pulls the second feeding pipe to move at the discharge port, and prevent granules from falling out of the feeding box when the second feeding pipe feeds material into the drying chamber. It has a simple structure, good stability, and can reduce the leakage of plastic granules. Attached Figure Description

The output end of the cylinder 9 is fixedly connected to the second feeding pipe 4. A filter plate 5 is provided on the first feeding pipe 3. A collection frame 6 is provided on one side of the filter plate 5. The collection frame 6 is fixedly connected to the feeding box 2. A motor 8 is installed on one side of the feeding box 2. A spiral auger 12 is provided inside the feeding box 2. One end of the spiral auger 12 is fixedly connected to the output end of the motor 8. A discharge port 14 is opened on the side of the feeding box 2 near the drying chamber 1. A baffle 15 is provided at the discharge port 14. Several elastic components 16 are connected to one side of the baffle 15. The elastic components 16 are fixed to the feeding box 2.
[0026] Furthermore, the side of the second feed pipe 4 away from the feed box 2 is attached to the drying chamber 1, and the drying chamber 1 is provided with a feed inlet, with the second feed pipe 4 corresponding to the feed inlet.
[0027] It should be noted that by setting a movable second feed pipe 4 on the drying chamber 1, a certain amount of plastic granules can be fed into the drying chamber 1, making it easy for people to control the amount of plastic granules fed into the drying chamber 1.
[0028] Furthermore, the side of the first feed pipe 3 is rotatably connected to the filter plate 5, and both the filter plate 5 and the feed box 2 are rotatably connected to connecting blocks 10, with springs 11 connecting between the connecting blocks 10.
[0029] It should be noted that by setting a connecting block 10 and a spring 11 on one side of the filter plate 5 to connect with the feed box 2, the filtered debris can be poured into the collection frame 6, which facilitates the filtration of the input particles.
[0030] Furthermore, a cavity 13 is provided on the side of the feed box 2 near the drying chamber 1, and a baffle 15 is slidably connected inside the cavity 13, and the baffle 15 corresponds to the discharge port 14.
[0031] It should be noted that by setting a baffle 15 at the discharge port 14, the particles can be prevented from leaking from the inside of the feed box 2, which helps to reduce particle waste.
[0032] Furthermore, the elastic component 16 consists of an elastic part and a telescopic rod. The elastic part is sleeved on the outside of the telescopic rod, and the elastic component 16 is arranged laterally on the feed box 2.

[0035] It should be noted that by setting guide rail 7 on the drying chamber 1, the sliding trajectory of the second feed pipe 4 can be guided, which helps to improve the stability of the second feed pipe 4.
[0036] The working principle of this PE plastic granule drying and feeding system is as follows: During use, granules are fed into the first feed pipe 3. The granules fall onto the filter plate 5, keeping the filter plate 5 in contact with the first feed pipe 3. After feeding is complete, the spring 11 pulls the connecting block 10 towards the feed box 2. At this time, one end of the filter plate 5 rotates towards the collection frame 6, and the impurities contained in the granules are directly poured into the collection frame 6. Finally, the motor 8 is started, causing the auger 12 to transport the granules to the outlet 14. Then, the cylinder 9 is activated to pull the second feed pipe 4 towards the feed box 2. Under the push of the second feed pipe 4, the baffle 15 retracts into the cavity 13. After the second feed pipe 4 has finished receiving the material, the elastic component 16 pushes the baffle 15 to automatically reset. Finally, the cylinder 9 controls the second feed pipe 4 to reset on the guide rail 7, allowing the granules to be fed into the drying chamber 1.
[0037] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
