Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic granule processing technology, and more specifically, to a feeder for plastic granule production. Background Technology
[0002] Plastic granules are granular substances produced by processing various high-molecular polymers through specific processes. They are important starting materials for subsequent plastic molding processes such as injection molding, extrusion, and blow molding, and are convenient to store, transport, and accurately meter for use in the production of different plastic products.
[0003] In plastic granule production, a feeder is needed to deliver the granules into the corresponding processing equipment. Existing screw feeders are prone to blade damage when conveying high-strength plastic granules, requiring regular maintenance and repair. Furthermore, screw feeders are highly versatile and inconvenient for screening and feeding plastic granules of different sizes, resulting in poor practicality. Therefore, we propose a feeder for plastic granule production. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a feeder for plastic pellet production to solve the technical problems of the current equipment's spiral feeding which easily damages the blades and is inconvenient for screening and feeding plastic pellets of different sizes.
[0005] To solve the above technical problems, this utility model provides the following technical solution: a feeding machine for producing plastic granules, comprising a frame, a storage mechanism, a shell, and a partition structure. A top cover is installed at the upper opening of the frame, and both ends of the top cover have inlet ports. An unfolding opening is provided on both sides of the frame. The shell is installed inside the frame, and both sides of the shell have side cavities. An adjustment port is provided in the middle of the front and rear end faces of the shell. Arc-shaped openings are provided on both sides of the front and rear end faces of the shell. The storage mechanism is rotatably installed in the unfolding opening via a rotating shaft. The storage mechanism consists of a hopper, and movable rods are fixed on both sides of the hopper. The inner side of the hopper is inserted into the side cavity. The partition structure is installed inside the hopper. A discharge port is provided at the bottom of the inclined surface at the lower end of the hopper.
[0006] In use, this utility model is powered by an external power supply. The operator starts the device through an external control device. Plastic granules are introduced into the hopper through the feed inlet and the cavity separated by the partition structure. Small plastic granules pass through the inner side of the screening port. The vibration motor box is activated to complete the vibration and screening. The small plastic granules are discharged directly out of the discharge port. Through the above structural design, this device can screen raw materials of different sizes during the feeding process, ensuring that the raw materials required for processing meet the particle diameter and ensuring the quality of subsequent processing. The electric telescopic component is activated to drive the adjusting rod to descend, which in turn drives the moving rod synchronously with the linkage arm. The displacement within the arc-shaped opening causes the hopper to deflect downwards and open. During the opening process, the traction block engages with the traction groove, causing it to synchronously pull the partition structure to rotate and open. Large particles in the partition structure's cavity are directly discharged outwards through the opening gap. Through the above structural design, this device has a staged opening method. The hopper does not affect the partition structure in the initial opening state. When the hopper angle is appropriate, the traction block connects to the traction groove to synchronously drive the partition structure to rotate and open. The above principle can first complete the discharge of small particles remaining in the hopper, and then discharge the large particles as a whole, preventing material residue from re-mixing and affecting the material handling effect.
[0007] Preferably, the outer shell has an internal cavity in the middle, and the internal cavity is provided with a linkage mechanism. The linkage mechanism consists of a linkage arm, an adjusting rod and a telescopic component, and the telescopic component is installed inside the internal cavity.
[0008] Preferably, the two ends of the adjusting rod are slidably installed in the corresponding adjusting ports, the movable rod is slidably installed in the corresponding arc-shaped port, the arc-shaped port is the same as the axis of the hopper rotating shaft, the linkage arm is located on the outside of the outer shell, and the two ends of the linkage arm are respectively rotatably connected to the movable rod and the adjusting rod.
[0009] Preferably, the partition structure is an L-shaped structure composed of longitudinal plates and transverse plates. Screening ports are provided on both the longitudinal and transverse plates. The sides of the longitudinal and transverse plates are attached to the inner wall of the hopper. A vibration motor box is provided at one end of the transverse plate that is attached to the side cavity.
[0010] Preferably, the upper end of the longitudinal plate is rotatably mounted at the upper opening of the hopper via a hinge, and a base frame is fixed to the bottom of the longitudinal plate, with traction grooves opened at both ends of the base frame.
[0011] Preferably, traction blocks are fixed on both sides of the bottom of the hopper, and the traction blocks are inserted into the traction groove. The top of the traction block is provided with a pull rod, and the length of the pull rod is greater than the width of the traction groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, through the design of a partition structure, allows plastic granules to be introduced into the hopper from the inlet and separated into cavities by the partition structure. Small plastic granules pass through the inner side of the screening port, and the vibration motor box is activated to complete the vibration and screening. The small plastic granules are then discharged directly from the discharge port. Through the above structural design, this device can screen raw materials of different sizes during the feeding process, ensuring that the raw materials required for processing meet the particle diameter and ensuring the quality of subsequent processing.
[0014] 2. This utility model also designs a hopper, in which the electric telescopic component drives the adjusting rod to descend, and the linkage arm synchronously drives the movable rod to move within the arc-shaped opening, causing the hopper to deflect downwards and open. During the opening process, the traction block engages with the traction groove, synchronously pulling the partition structure to complete the rotation and opening. Large particles in the partition structure's cavity are directly discharged outwards through the opening gap. Through the above structural design, this device has a staged opening method. The hopper does not affect the partition structure in the initial opening state. When the hopper angle is appropriate, the traction block connects with the traction groove to synchronously drive the partition structure to rotate and open. The above principle can first complete the discharge of small particles remaining in the hopper, and then discharge the large particles as a whole, preventing material residue from re-mixing and affecting the material handling effect.

Arc-shaped openings 402 are located on both sides of the front and rear end faces of the shell 4. An internal cavity 403 is located in the middle of the shell 4, and a linkage mechanism 5 is installed within the internal cavity 403. The linkage mechanism 5 consists of a linkage arm 501, an adjusting rod 502, and a telescopic component 503. The telescopic component 503 is installed inside the internal cavity 403. The two sides of the adjusting rod 502... The end is slidably installed in the corresponding adjustment port 401, and the movable rod 302 is slidably installed in the corresponding arc-shaped port 402. The arc-shaped port 402 is the same as the axis of the rotating shaft of the hopper 301. The linkage arm 501 is located outside the outer shell 4, and the two ends of the linkage arm 501 are respectively rotatably connected to the movable rod 302 and the adjustment rod 502. Plastic granules are introduced into the hopper 301 through the cavity separated by the partition structure 6 from the feed port 101. Small plastic granules pass through the inner side of the screening port 606, and the vibration motor box 605 is activated to complete the vibration strengthening screening. Small plastic granules are discharged directly out from the discharge port 304. Through the above structural design, this device can screen raw materials of different sizes during the feeding process to ensure that the raw materials required for processing meet the particle diameter and ensure the quality of subsequent processing.
[0026] like Figures 3 to 9As shown, this utility model relates to a feeding machine for producing plastic granules, including a frame 2, a material storage mechanism 3, a shell 4, and a partition structure 6. The material storage mechanism 3 is rotatably installed in the opening 201 via a rotating shaft. The material storage mechanism 3 is composed of a hopper 301, and movable rods 302 are fixed on both sides of the hopper 301. The inner side of the hopper 301 is inserted into the side cavity 404. The partition structure 6 is installed inside the hopper 301. A discharge port 304 is opened at the bottom of the inclined surface at the lower end of the hopper 301. The partition structure 6 consists of longitudinal plates 6 The longitudinal plate 601 and the horizontal plate 604 form an L-shaped structure. Both the longitudinal plate 601 and the horizontal plate 604 have screening openings 606. The sides of the longitudinal plate 601 and the horizontal plate 604 are attached to the inner wall of the hopper 301. A vibration motor box 605 is located at one end of the horizontal plate 604 that is attached to the side cavity 404.

During the opening process, the traction block 303 engages with the traction groove 603, which synchronously pulls the partition structure 6 to complete the rotation and opening. Large particles in the partition structure 6 are directly discharged out through the opening gap. Through the above structural design, the device has a staged opening method. The hopper 301 does not affect the partition structure 6 when it is initially opened. When the angle of the hopper 301 is appropriate, the traction block 303 connects to the traction groove 603 to synchronously drive the partition structure 6 to complete the rotation and opening. The above principle can first complete the discharge of small particles remaining in the hopper 301, and then discharge the large particles as a whole, preventing the material residue from being remixed and affecting the material handling effect.
