Description

Technical Field

[0001] This utility model belongs to the field of shredder technology, and more specifically, it relates to a cutting device for a shredder. Background Technology

[0002] A shredder is a machine used for coarse crushing, generally for processing unprocessed raw materials or scraps in the recycling industry, making them smaller in size. Common shredder structures include three types: dual-shaft (or four-shaft) shearing type, single-shaft roller cutting type, and tearing type. The most common is the shearing shredder, which has two to four cutter shafts and mainly relies on the principle of "shearing and cutting" to complete the crushing process. The principle of this type of shredder is to crush objects like scissors. The roller cutting shredder has multiple blades mounted on a rotating cutter roller, which forms a cutting action with the fixed blades to achieve the effect of crushing materials. The principle of the tearing coarse shredder is to swing hooks to tear the waste material. This type of machine is mainly used for coarse crushing.

[0003] The output size of a shredder is closely related to the number of teeth on the moving blades and the gap between them. Generally, the smaller the output size, the higher the shredding cost. Shredders are widely used for shredding solid waste such as wood, mattresses, sofas, PE pipes, plastic bottles, waste copper wire, circuit boards, thin metals, medical supplies, waste household appliances, vehicle recycling, and household garbage. For materials that do not require a high degree of fineness, the output size can be controlled by reducing the number of moving blades. Conversely, for materials that require a high degree of fineness, the number of moving blades can be increased to make the output finer. However, currently, the moving blades are mostly fastened with bolts, which is troublesome to disassemble and wastes a lot of manpower and resources. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a cutting device for a shredder, thereby resolving the issues raised in the background art.

[0005] The purpose and effectiveness of the cutting device for a shredder in this utility model are achieved by the following specific technical means:

[0006] A cutting device for a shredder includes a cutting roller and a telescopic mechanism. The cutting roller includes a roller body with fixed cutters and openings arranged in annular alternation on the roller body. Several fixed cutters are provided and staggered. The openings are located between the fixed cutters and their positions are staggered with the fixed cutters. A telescopic mechanism is installed inside the roller body. The telescopic mechanism includes a telescopic arc plate with several telescopic cutters arranged in an alternating pattern on the telescopic arc plate. The positions of the telescopic cutters correspond to the positions of the openings on the roller body.

[0007] Furthermore, the roller body is provided with drive shafts at both ends, a driven gear is fixedly connected to the drive shaft at one end of the roller body, a drive gear is meshed on one side of the driven gear, a drive motor is provided at one end of the drive gear, and a protective cover is provided at one end of the roller body.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by driving the drive motor to rotate the drive gear, the driven gear is driven to rotate under the meshing transmission of the gear, thereby realizing the overall rotational movement of the cutting roller.

[0009] Furthermore, a fixed blade body is provided on the outer side of the roller body. The fixed blade body is fixedly installed on the crusher housing. The cutting edge of the fixed blade body is serrated, and both the fixed cutter and the telescopic cutter form an interlocking cutting action with the fixed blade body.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the material can be easily shredded by the interlocking cutting of the fixed blade body, the fixed cutter, and the telescopic cutter.

[0011] Furthermore, the telescopic mechanism also includes a fixing member, which is fixedly installed inside one end of the roller body, and a telescopic cylinder is installed inside the fixing member.

[0012] Furthermore, the output end of the telescopic cylinder is connected to a telescopic rod, and the outer wall of the telescopic rod is provided with multiple sets of No. 1 connecting seats, and each set of No. 1 connecting seats is hinged to a No. 1 H-shaped connecting rod.

[0013] Furthermore, each of the multiple sets of the first H-shaped connecting rods is also hinged to a first connecting seat at the other end, and the multiple sets of the first connecting seats are installed on the inner wall of the multiple sets of telescopic arc plates.

[0014] Furthermore, the outer wall of the fixing component is provided with multiple sets of No. 2 connecting seats, each set of No. 2 connecting seats is hinged to a No. 2 H-shaped connecting rod, and the other end of each set of No. 2 H-shaped connecting rod is hinged to another set of No. 2 connecting seats. The multiple sets of No. 2 connecting seats are fixedly installed on the inner wall of multiple sets of telescopic arc plates.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by driving the telescopic rod with the telescopic cylinder, and with the drive of multiple sets of No. 1 connecting seats and No. 1 H-type connecting rods, and the cooperation of multiple sets of No. 2 connecting seats and No. 2 H-type connecting rods, it is easy to realize the telescopic arc plate extension and retraction simultaneously. In addition, the number of cutters on the roller surface can be adjusted according to the material shredding production requirements, so as to control the fineness of the output, reduce manual operation, and save a lot of manpower and material resources.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This cutting device for a shredder uses a telescopic cylinder to drive a telescopic rod. Driven by multiple sets of No. 1 connecting seats and No. 1 H-shaped connecting rods, and in coordination with multiple sets of No. 2 connecting seats and No. 2 H-shaped connecting rods, it facilitates the synchronous extension and retraction of the telescopic arc plate. This allows for adjustment of the number of cutters on the roller surface, enabling control over the fineness of the output material. It reduces manual operation and saves significant manpower and resources. A drive motor drives a drive gear to rotate, which in turn drives a driven gear, resulting in the overall rotation of the cutting roller. The material is then shredded through the meshing of the fixed cutter body, fixed cutters, and telescopic cutters. This invention features a simple and reasonable structure, novel design, and easy and convenient assembly, making it highly practical. Attached Figure Description
