Description

Technical Field

[0001] This utility model belongs to the technical field of rotational molding granule feeding equipment, and particularly relates to a storage and feeding device for rotational molding special materials. Background Technology

[0002] A patent titled "Plastic Granule Feeding and Packaging Equipment" is published in the existing Chinese patent database. The application number is CN202323280563.4, and the application date is 2023-12-04. This equipment includes a packaging machine body, a belt conveyor, and an anti-blocking feeding mechanism. The anti-blocking feeding mechanism includes a distributing cylinder, a square inlet, a square outlet, a distributing cylinder, and a servo motor. The square inlet and the square outlet are respectively connected and fixed to the top and bottom of the distributing cylinder. The distributing cylinder is rotatably mounted inside the distributing tube, and multiple distributing slots are evenly spaced along the circumference on the distributing cylinder. The plastic granule feeding and packaging equipment of this utility model uses a servo motor to drive the distributing cylinder to rotate through an anti-blocking feeding mechanism. When the distributing slot rotates to the top, the plastic granules fall into the distributing slot under the action of gravity. When the distributing slot rotates to the bottom, the plastic granules fall out of the distributing slot under the action of gravity and are discharged from the square discharge port, thus avoiding the occurrence of material blockage accidents and achieving quantitative feeding.

[0003] In existing technologies, rotational molding granules are mostly stored in boxes or cylinders before use. When they are needed, manual scooping of the material from the box or cylinder is required, resulting in poor automation. This paper aims to propose a storage and feeding device for rotational molding granules, providing automated feeding operations. Utility Model Content

A material blocking assembly is hinged between the two first hinge seats. A second hinge seat is welded to the side of the upper open portion. A cylinder is hinged to the second hinge seat and arranged at an incline. A third hinge seat is welded to the side of the material blocking assembly. The piston rod lug section of the cylinder is connected to the third hinge seat.

[0007] As a preferred embodiment, the material blocking assembly includes side baffles that are respectively hinged to each of the first hinge seats, and an arc-shaped lower baffle is integrally provided between the bottoms of the two side baffles.

[0008] As a preferred embodiment, a receiving port is integrally welded onto the frame located directly below the material blocking assembly. The receiving port is formed by welding several plates together to form a rectangle. A discharge port is provided on the frame located below the receiving port. A receiving cylinder is placed inside the frame located directly below the discharge port. The opening size of the discharge port is the same as the opening size of the receiving cylinder.

[0009] As a preferred embodiment, the outer central part of the cylinder is hinged to the second hinge seat via a pivot pin.

[0010] As a preferred embodiment, the frame includes an upper frame and a lower frame, the upper opening of the hopper is welded to the upper frame, a horizontal plate is provided between the upper frame and the lower frame, the receiving port is located above the horizontal plate, and the discharge port is located below the horizontal plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the device controls the rotation of the baffle assembly by a cylinder to control the opening and closing of the lower end of the hopper, so that the rotational molding particles in the hopper fall stably and are easy for workers to pick up. The device is suitable for industrial production and has strong practicality. Attached Figure Description

Detailed Implementation

[0014] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1The diagram shows a storage and feeding device for rotational molding materials, comprising a frame 1, on which a feeding hopper 2 is fixedly welded. The feeding hopper 2 includes an upper open portion 201 and a lower narrow portion 202. First hinge seats 3 are welded to both the front and rear surfaces of the lower narrow portion 202. A material-blocking assembly 4 is hinged between the two first hinge seats 3. A second hinge seat 5 is welded to the side of the upper open portion 201, and a downwardly inclined cylinder 6 is hinged to the second hinge seat 5. A third hinge seat 7 is welded to the side of the material-blocking assembly 4, and the piston rod lug section of the cylinder 6 is connected to the third hinge seat 7. The material-blocking assembly 4 includes side baffles 401 respectively hinged to each of the first hinge seats 3, and an arc-shaped lower baffle 402 integrally formed between the bottoms of the two side baffles 401. A receiving port 8 is integrally welded onto the frame 1 located directly below the material blocking assembly 4. The receiving port 8 is rectangularly arranged by welding several plates together. A discharge port 9 is provided on the frame 1 located below the receiving port 8. A receiving cylinder 10 is placed inside the frame 1 located directly below the discharge port 9. The opening size of the discharge port 9 is the same as the opening size of the receiving cylinder 10. The outer side of the middle part of the cylinder 6 is hinged to the second hinge seat 5 via a pin shaft. The frame 1 includes an upper frame 101 and a lower frame 102. The upper open part 201 of the hopper 2 is welded to the upper frame 101. A horizontal plate 103 is provided between the upper frame 101 and the lower frame 102. The receiving port 8 is located above the horizontal plate 103, and the discharge port 9 is located below the horizontal plate 103.

[0016] During operation, the operator controls the extension and retraction of cylinder 6 to open and close the bottom discharge port of hopper 2. When the piston rod of cylinder 6 is extended, the baffle assembly 4 is positioned directly below the narrow opening 202 of hopper 2, blocking the narrow opening 202. When the piston rod of cylinder 6 is retracted, cylinder 6 swings slightly within the second hinge seat 5, while the baffle assembly 4 rotates clockwise around the axis of the first hinge seat 3, thereby opening the narrow opening 202 of hopper 2 to discharge plastic granules. The operator places the receiving cylinder 10 inside the frame 1, and the plastic granules pass through the receiving port 8 and the discharge port 9 in sequence before finally falling into the receiving cylinder 10.
