Description

Technical Field

[0001] This utility model relates to the field of blade roller technology, and in particular to the blade roller structure of a dual-shaft shredder. Background Technology

[0002] As a core piece of equipment in solid waste treatment and industrial material crushing, the performance of the cutter roller structure of a twin-shaft shredder directly determines its shredding efficiency, material adaptability, and equipment maintenance costs. However, existing twin-shaft shredder cutter roller structures have significant technical shortcomings in practical applications, making it difficult to meet diverse crushing needs and the requirements for efficient operation and maintenance. On the one hand, most existing cutter rollers use a fixed spacing design, which can only crush materials with specific hardness and size. When processing materials of different materials or thicknesses, it is impossible to adapt the roller spacing to the material characteristics. With softer materials, the spacing is too small, which can lead to excessive compression and clumping. With harder materials, the spacing is too large, which can result in incomplete tearing. At the same time, some cutter rollers with adjustable spacing are prone to inconsistent spacing at both ends during adjustment, resulting in uneven force on the cutter roller during operation. On the other hand, the existing cutter head replacement process for cutter rollers is cumbersome and inefficient. Traditional cutter heads are mostly welded as a whole. When the cutter head needs to be replaced due to wear or cracking, the entire cutter roller must be disassembled first, which is a complex and time-consuming operation. Especially in continuous production scenarios, the excessive downtime caused by cutter head replacement can directly interrupt the production process and reduce overall production efficiency.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-4 The present invention relates to a dual-shaft shredder cutter roller structure, which includes a crushing box 1. Two first rotating rods 12 and a second rotating rod 15 are rotatably connected to the inner wall of the crushing box 1. Multiple second turntables 14 are provided on one side of the first rotating rods 12. A pressure knife 6 is slidably connected to the outer wall of the second turntables 14. Sliding rods 9 and connecting rods 4 are provided on both sides of the crushing box 1. A lead screw 10 is threadedly connected to the inner wall of the sliding rod 9.

[0017] A rotating shaft 13 is fixedly connected to one side of the first rotating rod 12. The outer wall of the rotating shaft 13 is fixedly connected to the inner wall of the second turntable 14. Multiple first turntables 5 are fixedly connected to the outer wall of the rotating shaft 13. The second turntable 14 is fixedly connected to one side of the first turntable 5.

[0018] Specifically, the rotation of the first rotating rod 12 causes the first turntable 5 and the second turntable 14, which are mounted on the outer wall of the rotating shaft 13, to rotate, thereby causing the parts on the turntable to rotate.

[0019] The lower end of the pressure knife 6 is fixedly connected to a locking pin 16, which is rotatably connected to the inner wall of the second turntable 14.

[0020] Specifically, the lower locking pin 16 can prevent the pressure knife 6 from falling off during the rolling process and enhance the strength of the pressure knife 6.

[0021] The inner wall of the pressure knife 6 is slidably connected with a first nut 17 and a second nut 18, and the outer walls of the first nut 17 and the second nut 18 are threadedly connected to the inner wall of the second turntable 14.

[0022] Specifically, the first nut 17 and the second nut 18 can be used to fix the pressure knife 6. When the pressure knife 6 is damaged, the first nut 17 and the second nut 18 can be used to facilitate the replacement of the damaged pressure knife 6.

[0023] The first rotating rod 12 is fixedly connected to one side of the first motor 2. The output end of the first rotating rod 12 and the first motor 2 are fixedly connected. The first fixing block 8 is fixedly connected to one side of the first motor 2. The first fixing block 8 is fixedly connected to one side of the connecting rod 4.

[0024] Specifically, the first motor 2 drives the first rotating rod 12 to rotate, thereby driving the cutter roller to rotate and roll the material.

[0025] The outer walls of the first rotating rod 12 and the second rotating rod 15 are rotatably connected to a rotating groove 7. One side of the rotating groove 7 is fixedly connected to one side of the connecting rod 4, and one side of the connecting rod 4 is fixedly connected to both ends of the sliding rod 9.

[0026] Specifically, the outer walls of the first rotating rod 12 and the second rotating rod 15 are rotatably connected to the rotating groove 7, and the sliding rod 9 provided on one side of the rotating groove 7 can drive the first rotating rod 12 and the second rotating rod 15 to move.

[0027] One side of the lead screw 10 is rotatably connected to the inner wall of the crushing box 1, and the other side of the lead screw 10 is fixedly connected to the second motor 3. The output ends of the lead screw 10 and the second motor 3 are fixedly connected.

[0028] Specifically, the working principle of the lead screw 10 is mainly to convert the rotational motion into linear motion through the friction of the thread. By setting the lead screw 10 and the second motor 3, the distance between the cutter rollers can be adjusted to crush different types of materials.

[0029] The lower end of the second motor 3 is fixedly connected to the second fixing block 11, and one side of the second fixing block 11 is fixedly connected to the outer wall of the crushing box 1.

[0030] Specifically, the second fixing block 11 is fixed on one side of the crushing box 1 to fix the position of the second motor 3.

[0031] Working principle: The pressure knife 6 and the locking pin 16 below it can be locked in place to prevent it from detaching and enhance its strength. The first nut 17 and the second nut 18 inside the pressure knife 6 fix its position to the outer wall of the second turntable 14. Then, the first motor 2 drives the first rotating rod 12, which in turn drives the rotating shaft 13 to rotate. This, in turn, drives the first turntable 5 and the second turntable 14 fixed to the outer wall of the rotating shaft 13 to rotate, thus causing the pressure knife 6 to crush the material. When crushing different materials, the second motor 3 on both sides of the crushing box 1 can be controlled to rotate the lead screw 10, which drives the sliding rod 9, pulling the first rotating rod 12 and the second rotating rod 15 at both ends to move, thereby adjusting the distance between the crushing rollers to adapt to crushing different materials. This improves adaptability.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
