Description

Technical Field

[0001] The utility model relates to the technical field of single-shaft shredders, in particular to a knife roller structure for a single-shaft shredder. Background Art

[0002] The knife roller structure of the single-shaft shredder is relatively unique. It is mainly designed for effective crushing of materials. As the core component of the entire knife roller, the knife shaft is responsible for driving the blade to rotate. The design of the knife shaft usually takes into account strength and wear resistance to ensure long-term stable operation. The working principle of the single-shaft shredder is relatively simple. The motor drives the knife shaft to rotate, and the blade rotates with the knife shaft and shears, tears and crushes the material. Under the action of the blade, the material is gradually broken into small pieces and discharged through the discharge port of the machine. The knife roller structure of the single-shaft shredder has unique design features and significant application advantages. In actual application, users can choose the appropriate model and configuration according to the nature of the material and the crushing requirements.

[0003] The prior art patent document CN219024539U provides a knife roller structure for a single-shaft shredder. The device first arranges a mounting surface on the main shaft so that the bottom surface of the base can be more stably and firmly mounted on the main shaft, and then increases the connection strength with the blade through the extension portion on the knife seat, so that the connection strength between the movable knife and the main shaft can match the single-shaft shredder with large torque, and the device can cut out uniform and regular material sizes through a regular first cutting edge, while ensuring precise cutting requirements, it can also reduce the waste of mechanical energy. In addition, by arranging multiple mounting surfaces on the outer peripheral surface of the main shaft and multiple movable knives arranged in sequence on the mounting surfaces, when the main shaft rotates, there are always movable knives and fixed knives on the main shaft to cooperate with each other for cutting, thereby improving the working efficiency of the single-shaft shredder.

[0004] However, the knife roller structure used in the single-shaft shredder in the prior art is usually a fixed type. When the blade or related parts on the knife roller are damaged, due to the integrity of the structure, it is often necessary to replace the entire shredding knife roller instead of replacing the damaged parts separately. The blade or related parts cannot be replaced separately, so the entire knife roller needs to be replaced, which not only increases maintenance costs, but may also affect production progress. Utility Model Content

[0005] The purpose of the present utility model is to provide a knife roller structure for a single-shaft shredder to solve the existing problems raised in the above background technology.

[0007] Preferably, there are multiple rollers on the positioning rod, and the multiple rollers are evenly spaced on the outer wall of the positioning rod.

[0008] Preferably, the positioning rod forms a fixed structure with the roller body through a long bolt, and the nut is fastened to the outer wall of the long bolt for installation.

[0009] Preferably, the roller body forms a combined structure with the positioning rod through the positioning groove, the inner diameter of the positioning groove matches the outer diameter of the positioning rod, and the outer wall of the positioning rod is fitted with the positioning groove.

[0010] Preferably, the knife roller assembly includes a card slot, the interior of the card slot is engaged with a card plate, the top of the card plate is fixedly connected to a crushing blade, and the top of the crushing blade is provided with a fixing bolt.

[0011] Preferably, the roller body forms a combined structure with a clamping plate through a clamping slot, the inner diameter of the clamping slot matches the outer diameter of the clamping plate, and one end of the clamping plate extends into the clamping slot for connection.

[0012] Preferably, the crushing blade forms a fixed structure with the roller body through fixing bolts, and the number of the fixing bolts is four, and the four fixing bolts all pass through the crushing blade and are fastened in the roller body for installation.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. By loosening and disassembling the nut on the long bolt, the nut can be separated from the fastening and installation of the roller body. In addition, by pulling the roller body, the roller body can slide along the outer wall of the positioning rod by relying on the internal positioning groove, so that the roller body can be disassembled. The detachable knife roller structure can facilitate the replacement of damaged areas of the knife roller. By backing up multiple separate accessories, the accessories of the damaged area of the shredder can be quickly replaced in time, without the need to purchase multiple entire knife rollers, which can save production costs.

[0015] 2. The card plate on the crushing blade is fastened in the card slot and fastened by the fixing bolts, which can not only effectively prevent the components from loosening or falling off during operation, but also improve the rigidity and stability of the entire cutter roller. The fixing bolts on the crushing blade can be loosened and disassembled, so that the fixing bolts can be detached from the fastening of the crushing blade. At this time, the crushing blade can be taken out first, so that the card plate can be detached and taken out from the card slot, which is convenient for people to disassemble and install the crushing blade on the cutter roller structure separately, and can reduce the need for replacing and using the crushing blade separately.

The fixing bolts 404 provided pass through the reserved holes on the crushing blade 403 and the roller body 3, and are tightened to generate sufficient pre-tightening force, thereby firmly locking the crushing blade 403 in the card slot 401. By loosening and removing the fixing bolts 404 on the crushing blade 403, the fixing bolts 404 can be disengaged from the fastening of the crushing blade 403. At this time, the crushing blade 403 can be taken out first, and the card plate 402 can be detached and taken out from the card slot 401, which can facilitate people to separately disassemble and install the crushing blade 403 on the knife roller structure, and can improve the need for separate replacement and use of the crushing blade 403.

[0025] Working principle: When the roller body 3 in a single area needs to be disassembled and replaced, the entire knife roller structure can be disassembled first, and then the nut 203 on the long bolt 202 can be loosened and disassembled, so that the nut 203 can be separated from the fastening and installation of the roller body 3. In addition, the roller body 3 can be pulled so that the roller body 3 can slide along the outer wall of the positioning rod 201 by relying on the internal positioning groove 204, thereby achieving the disassembly of the roller body 3. By setting up a detachable knife roller structure, it is convenient to replace the damaged area of the knife roller separately, which can save production costs. In addition, the crushing blade 403 is fastened in the card slot 401 by the card plate 402 at the bottom and then fastened by the fixing bolt 404, and at the same time, this installation structure and the card plate 402 are fastened to the card The close fit between the grooves 401 forms a stable structure, and after being installed and reinforced by the fixing bolts 404, it can not only effectively prevent the components from loosening or falling off during operation, but also improve the rigidity and stability of the entire knife roller, thereby ensuring the crushing efficiency and safety of the single-axis shredder. At the same time, when the roller body 3 is not damaged, the fixing bolts 404 on the crushing blade 403 can be loosened and disassembled, so that the fixing bolts 404 can be detached from the fastening of the crushing blade 403. At this time, the crushing blade 403 can be taken out first, and the card plate 402 can be detached and taken out from the card slot 401, which can facilitate people to separately disassemble and install the crushing blade 403 on the knife roller structure, and can reduce the need for separate replacement and use of the crushing blade 403.
