Description

A cutting blade for a shredder Technical Field

[0001] This utility model relates to the field of cutting blades, and more particularly to a cutting blade for a shredder. Background Technology

[0002] In modern industrial production, resource recycling, and material processing, pulverizers are widely used as key equipment to crush various materials into specific shapes to meet the needs of subsequent processes or applications. As the core component of the pulverizer, the performance and design of the cutting blade directly determine the pulverizer's cutting efficiency, effect, and applicable range.

[0003] Existing shredders typically involve mounting blades on the shredder shaft, which rotates to cut the material. However, most current shredders use a single, fixed cutting blade, making it impossible to flexibly adjust the number or position of the blades according to specific needs. This makes it difficult to adapt to different cutting requirements, easily affecting cutting efficiency and effectiveness, resulting in material waste and significant inconvenience.

[0004] Therefore, it is necessary to design a cutting blade for shredders that can be used with multiple blade holders and blades according to the material being cut, while adjusting the blade position for cutting. This would facilitate adaptation to different cutting needs, improve cutting efficiency and effect, reduce material waste, and provide a flexible and convenient cutting solution. Summary of the Invention

[0005] To overcome the shortcomings of current shredders that mostly use a single fixed cutting blade, which cannot flexibly adjust the number or position of blades according to specific needs, making it difficult to adapt to different cutting requirements, easily affecting cutting efficiency and effect, causing material waste, and being very inconvenient to use, this utility model provides a cutting blade for shredders that can be equipped with multiple blade holders and blades according to the material being cut, and the blade position can be adjusted for cutting, making it easy to adapt to different cutting requirements, improving cutting efficiency and effect, reducing material waste, and making it flexible and convenient to use.

[0006] The technical solution is as follows: A cutting blade for a pulverizer includes a pulverizer shaft, a limiting block, a fastening knob, a partition block, a splicing boss, a mounting block, a blade holder, a blade body, and a fixing assembly. The lower part of the pulverizer shaft is connected to the limiting block, and the upper part of the pulverizer shaft is connected to the fastening knob via a thread. Multiple partition blocks are fitted on the pulverizer shaft, with the lowest partition block contacting the limiting block. Each partition block has a splicing boss connected to its upper side, and each splicing boss has a mounting block engaged with its upper part. Each mounting block engages with an adjacent partition block and is in contact with the pulverizer shaft. Each mounting block has a blade holder connected to its middle section, and multiple blade bodies are detachably connected to each blade holder. The blade holder has fixing assemblies on its front, back, left, and right sides for fixing and adjusting the blade bodies.

[0007] Furthermore, the separator blocks and mounting blocks are distributed in an alternating pattern.

[0008] Furthermore, splicing grooves are provided at the bottom of each mounting block.

[0009] Furthermore, the fixing component includes threaded sleeves and locking rods. Multiple threaded sleeves are connected to the lower sides of the front, rear, left, and right sides of the tool holder. Each threaded sleeve is connected to a locking rod by threads, and the locking rods pass through the adjacent blade body.

[0010] Furthermore, it also includes adjustment knobs, with adjustment knobs connected to the upper part of the locking lever.

[0011] Furthermore, multiple adjustment holes are provided on all four sides of the tool holder, front, back, left, and right.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses multiple partition blocks and mounting blocks to cross-fit onto the shaft of the crusher, and fixes them with fastening knobs, thereby installing the blade holder and blades. After pulling the blades to move, they are fixed with locking rods. Thus, multiple blade holders and blades can be installed and used simultaneously to adjust the blade position for cutting according to the material being cut. This makes it easy to adapt to different cutting needs, improves cutting efficiency and effect, reduces material waste, and is flexible and convenient to use.

[0013] 2. This utility model allows for the removal of the blade body by rotating the locking rod, followed by pulling the blade body to remove and replace it. The new blade body is then locked to the blade holder. The locking rod is then inserted into the corresponding adjustment hole, passing through the blade body and contacting the threaded sleeve. The locking rod is then rotated to move and fix the blade body in place. This allows for the installation and use of the blade body for cutting, facilitating the quick installation, removal, and replacement of individual blades, reducing maintenance costs, and improving ease of use.
