Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waste metal processing equipment, specifically to a waste metal plate shredding device. Background Technology
[0002] In the process of processing scrap metal sheets, it is sometimes necessary to cut the scrap metal sheets into small pieces for further processing.
[0003] The device used for cutting scrap metal sheets is a scrap metal sheet shredding device.
[0004] The scrap metal sheet shredding device includes a frame, a cutting platform mounted on the frame, and a gantry frame mounted on the frame. A hydraulic cylinder is mounted below the gantry frame, and a support plate is mounted below the hydraulic cylinder. Multiple parallel cutting blades are mounted below the support plate, each cutting blade having a lower cutting edge. When the hydraulic cylinder moves downwards, the cutting blades can cut the scrap metal sheet placed on the cutting platform into strip-shaped fragments. In existing technology, scrap metal sheet shredding devices only have one gantry frame and only one set of cutting blades below it, resulting in strip-shaped metal fragments that do not meet the requirement for finer metal fragments. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a waste metal plate shredding device that can produce smaller metal fragments to meet certain production requirements.
[0006] The technical solution of this utility model is implemented as follows: A waste metal sheet shredding device includes a frame, a cutting platform mounted on the frame, and a gantry frame mounted on the frame. A hydraulic cylinder is mounted under the gantry frame, and a support plate is mounted under the hydraulic cylinder. A cutting blade group consisting of multiple parallel cutting blades is mounted under the support plate. Each cutting blade has a lower cutting edge. The hydraulic cylinder moves downward, and the cutting blades can cut the waste metal sheets placed on the cutting platform. The waste metal sheets move from back to front on the cutting platform. The device is characterized by having two gantry frames: a rear gantry frame and a front gantry frame. The cutting blades mounted under one gantry frame have a front-to-back cutting edge, while the cutting blades mounted under the other gantry frame have a left-to-right cutting edge.
[0007] Furthermore, the cutting platform has high edges on both sides, which make the cutting platform inside the two high edges form a conveying channel for scrap metal.
[0008] Furthermore, the cutting platform also has spaced roller grooves, and rollers driven by a conveyor motor are installed in the roller grooves.
[0009] To elaborate further, the cutting blade assembly installed under the front gantry is the front cutting blade assembly, and the cutting blade assembly installed under the rear gantry is the rear cutting blade assembly. The distance between adjacent cutting blades in the front cutting blade assembly is smaller than the distance between adjacent cutting blades in the rear cutting blade assembly.
[0010] The beneficial effects of this utility model are: such a waste metal plate shredding device can produce smaller metal fragments, which can meet some production requirements. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] As shown in the figure, a waste metal sheet shredding device includes a frame 1, a cutting platform 11 mounted on the frame, a gantry frame 2 mounted on the frame, a hydraulic cylinder 3 mounted under the gantry frame, a support plate 4 mounted under the hydraulic cylinder, and a cutting blade group 5 formed by multiple parallel cutting blades 51 mounted under the support plate. Each cutting blade has a lower cutting edge 52. When the hydraulic cylinder moves downwards, the cutting blades can cut the waste metal sheets placed on the cutting platform. The waste metal sheets move from back to front on the cutting platform. The device is characterized by having two gantry frames: a rear gantry frame 21 and a front gantry frame 22. The cutting blades mounted under one gantry frame have a front-to-back cutting edge, while the cutting blades mounted under the other gantry frame have a left-to-right cutting edge.
[0017] The cutting blade assembly installed under the front gantry is the front cutting blade assembly, and the cutting blade assembly installed under the rear gantry is the rear cutting blade assembly.
[0018] Because this utility model has two sets of cutting blades with the blades perpendicular to each other, it can cut scrap metal into fragments instead of strips when cutting scrap metal sheets, thus fulfilling the purpose of this utility model.
[0019] When cutting scrap metal sheets, the forward propulsion of the scrap metal sheets can be achieved from the rear of this device. For example, a cleaning device for the scrap metal sheets can be installed at the rear of this device. The scrap metal sheets from the cleaning device are transported to this cutting device. The cleaning device continuously feeds scrap metal sheets onto this device, causing the rear metal sheets to push the front metal sheets forward. In this case, this device does not need to provide additional conveying components for the metal sheets.
[0020] When the hydraulic cylinder is fully extended, it ensures that the blade just touches the cutting platform.
[0021] A hydraulic cylinder 3 is installed under the gantry frame, and a support plate 4 is installed under the hydraulic cylinder. The hydraulic cylinder connects the gantry frame and the support plate. The hydraulic cylinder has a housing and a telescopic cylinder. For example, the housing is installed on the support plate, and the telescopic cylinder is installed on the gantry frame, which ensures that the support plate can move downward when the hydraulic cylinder extends.
[0022] Furthermore, the cutting platform has high edges 111 on both sides, which make the cutting platform inside the two high edges form a conveying channel for scrap metal.
[0023] This design facilitates the transport of scrap metal sheets and prevents them from slipping off the cutting platform during the cutting process.
[0024] Furthermore, the cutting platform also has spaced roller grooves, and rollers 6 driven by a conveyor motor are installed in the roller grooves.
[0025] This invention provides power for the conveying of metal plates, thus ensuring the forward movement of the waste metal plates.
[0026] To elaborate further, the cutting blade assembly installed under the front gantry is the front cutting blade assembly, and the cutting blade assembly installed under the rear gantry is the rear cutting blade assembly. The distance D2 between adjacent cutting blades in the front cutting blade assembly is smaller than the distance D1 between adjacent cutting blades in the rear cutting blade assembly.
[0027] This invention is designed in such a way that it can cut scrap metal into smaller pieces. Moreover, the design is reasonable because the scrap metal is already broken up when it reaches the front cutting blade assembly, making it easier to cut.
[0028] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
