Description

Technical Field

[0001] The invention relates to the technical field of granulation screws, in particular to a multi-section granulation screw. Background Art

[0002] The granulating screw is a rotating part installed inside the screw granulator, which is used to compress, mix and transport the materials to the mold to form granules. It generates shear force, extrusion force and friction force through rotation, so that the materials are plasticized, homogenized and melted in the high temperature and high pressure environment between the screw and the barrel, and finally extruded through the forming hole of the mold to become granular products.

[0003] Most of the screws of granulators are single screws. When they need to be replaced, some of the screw segments are not completely worn out and failed, which results in the entire screw being replaced as a whole. Even if only a small part of the screw segment is worn or failed, the entire screw needs to be replaced, which means that a large amount of still usable materials are wasted, and the removal and installation process of the entire screw is relatively complicated, requiring more time and manpower. This reduces maintenance efficiency and increases maintenance difficulty. After the overall replacement of the screw, other components related to the screw (such as the transmission system, heating system, etc.) need to be readjusted. Improper adjustment may affect the overall performance of the equipment.

The bidirectional fastening design can effectively resist these external forces and reduce the possibility of loosening. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Through the above embodiment, the effect achieved is: the feed screw 102 is driven externally to continuously rotate, so that the lever 208 on the rotating shaft 201 continuously shifts the material.

Example

[0028] Please refer to Figures 2 to 9 As shown: In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a multi-section granulation screw, including: a barrel 1, a material discharge box 101 is arranged on the barrel 1, a screw assembly is arranged in the barrel 1 and passes through the material discharge box 101, and the screw assembly is connected end to end to form a granulation screw; It also includes a fastening component 1, which is arranged on the screw component. The screw components are fastened to each other through the fastening component 1. The fastening component 1 includes an extension groove 301, and the extension groove 301 is symmetrically arranged on one of the screw components. Fixed rods 302 are symmetrically arranged in the extension groove 301, and fixed blocks 306 are arranged on the opposite surfaces of the fixed rods 302.

[0029] The fastening component 1 also includes a connecting groove 3, which is arranged at the head of the feeding screw 102, the compression screw 103, the mixing screw 104, and the dissolution screw 105. The connecting groove 3 is connected to the extension groove 301, and a card groove 307 is arranged on the groove wall of the connecting groove 3. A limiting block 303 is fixedly connected at the outlet of the extension groove 301, and the limiting block 303 is slidably connected to the fixed rod 302.

[0030] The outer surface of the fixing rod 302 is sleeved with an elastic member 1 305, and a limiting block 2 304 is provided at one end of the elastic member 1 305 away from the limiting block 1 303. The limiting block 2 304 is fixedly provided on the fixing rod 302, and the fixing block 306 on the fixing rod 302 is provided with an inclined surface and a horizontal surface.

[0031] Through the above embodiment, the effect achieved is: the head and tail of the screw assembly are connected and limited by the fastening component 1, thereby significantly enhancing the strength and stability of the entire connection structure. This design can withstand greater tension and shear forces, ensuring that the connection part is not easy to loosen or break when subjected to external loads. The limit design can ensure that the screw assembly will not accidentally fall off due to vibration, impact or other external factors during the connection process. This is particularly important for equipment that requires long-term stable operation or withstands complex working conditions. The operator only needs to align the screw assembly and install the fastening component 1 to complete the connection without complicated adjustments and calibrations. Example

[0032] Please refer to Figures 2 to 9 As shown: In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a multi-section granulation screw, including: a barrel 1, a material discharge box 101 is arranged on the barrel 1, a screw assembly is arranged in the barrel 1 and passes through the material discharge box 101, and the screw assembly is connected end to end to form a granulation screw; It also includes a fastening component 2, which is arranged on the screw component. The fastening component 2 provides a fastening force in the opposite direction to the fastening component 1 to increase the fixing effect. The fastening component 2 includes a fixing ring 411 and a threaded ring 410. The fixing ring 411 and the threaded ring 410 are respectively arranged on two screw components connected end to end. The screw component is provided with a connecting block 4, and a through groove 403 is opened on the connecting block 4. A clamping rod 409 is arranged in the through groove 403 to cooperate with the fixing ring 411 and the threaded ring 410 for fastening.

[0033] Furthermore, the fastening assembly 2 includes a connecting block 4 which is respectively arranged at the tail of the compression screw 103, the mixing screw 104, the dissolution screw 105 and the compression screw 2 106, and a bayonet 401 which is adapted to the horizontal plane of the fixing block 306 is provided on the connecting block 4, and an installation groove 402 is provided on the connecting block 4, and the installation groove 402 is divided into three sections with different diameters, namely a large diameter section, a medium diameter section and a small diameter section.

[0034] An extrusion rod 404 is disposed in the large diameter section of the installation groove 402 , and a linkage rod 412 is disposed above the extrusion rod 404 . The linkage rod 412 penetrates the screw assembly and extends to the outer surface of the screw assembly.

[0035] Furthermore, a connecting rod 405 is provided at the bottom of the extrusion rod 404, and the connecting rod 405 passes through the middle diameter section of the installation groove 402. A limiting block 3 406 is fixedly provided on the outer surface of the connecting rod 405, and an elastic member 2 407 is provided at the bottom of the limiting block 3 406. The elastic member 2 407 is limited at the bottom of the middle diameter section of the installation groove 402. A fixing plate 408 is fixedly provided on the outer surface of the connecting rod 405, and the fixing plate 408 and the clamping rod 409 are hinged to each other, and the clamping rod 409 is symmetrically arranged on the fixing plate 408, and the clamping rod 409 is adapted to the clamping groove 307.

[0036] Through the above embodiment, the effect achieved is: the clamping rod 409 of the fastening component 2 is engaged with the clamping groove 307, and the threaded ring 410 is rotated toward the side of the fixing ring 411 to further cooperate with the fastening component 1 to achieve bidirectional fastening. The fastening component 1 has provided a basic fastening effect for the screw rod component, and the addition of the fastening component 2 forms a double fastening mechanism. The engagement of the clamping rod 409 and the clamping groove 307 provides preliminary positioning and fastening, and the rotation of the threaded ring 410 further increases the strength and stability of the fastening. Under the action of external forces such as vibration and impact, a single fastening method is prone to loosening. The bidirectional fastening design can effectively resist these external forces, reduce the possibility of loosening, and ensure the stability and reliability of the connection part.

[0037] Through all the above embodiments, the working principle of the present invention is: After the external drive of the feed screw 102 is started, the feed screw 102 continues to rotate. When the feed screw 102 continues to rotate, the gear 1 2 rotates accordingly, driving the gear 3 204 above the gear 2 202 to rotate synchronously in the same direction, ensuring the continuity and stability of power transmission. The driving force of the machine itself enables the lever 208 on the rotating shaft 201 to continuously shift the material. The continuous rotation of the feed screw 102 and the continuous shifting of the lever 208 can effectively push the material forward and avoid the accumulation and blockage of the material during the conveying process. This dynamic movement mode helps the material to maintain a flowing state and reduce the possibility of stagnation and accumulation; and the protruding portion of the groove 205 is smaller than the length of the protrusion 207, allowing the collar 206 to be movable on the rotating shaft 201, increasing the flexibility and adaptability of the lever 208 when shifting the material, and further reducing the risk of blockage. In addition, the machine's own driving force drives the anti-blocking component, which means that it can directly use the movement or energy of the machine itself to drive the anti-blocking device, without the need for additional external power sources such as motors and hydraulic systems, reducing energy consumption, and complying with the environmental protection concept of energy conservation and emission reduction; Furthermore, when it is necessary to connect the screw rod assemblies end to end, it is only necessary to align the adjacent screw rod assemblies end to end. At this time, the bottom of the connecting block 4 will be aligned with the fixing block 306. When the screw rod assembly is pressed, the connecting block 4 will gradually approach and squeeze the inclined surface of the fixing block 306. At this time, the elastic member 1 305 compresses and prompts the fixing rod 302 to retract into the extension groove 301. When the bayonet 401 of the connecting block 4 gradually approaches and fits the horizontal surface of the fixing block 306, the elastic member 1 305 loses its restriction and prompts the fixing rod 302 to push the fixing block 306 out to initially fix the screw rod assemblies connected end to end. When disassembly is required, one of the interconnected screw assemblies is rotated. At this time, the outer surface of the connecting block 4 squeezes the fixed block 306, causing the fixed rod 302 to retract. When rotated 90 degrees, the fixed block 306 contacts the bayonet 401 of the connecting block 4 to limit the position, so that the connected screw assemblies can be disassembled for replacement or repair. When one of the screw assemblies fails or needs to be replaced, it can be quickly disassembled and replaced with a new assembly, reducing the difficulty and cost of maintenance. The head and tail of the screw assembly are connected and limited by the fastening assembly, thereby significantly enhancing the strength and stability of the entire connection structure. This design can withstand greater tension and shear forces, ensuring that the connection part is not easy to loosen or break when subjected to external loads. The limit design can ensure that the screw assembly will not accidentally fall off due to vibration, impact or other external factors during the connection process; Furthermore, while the fastening assembly is fixing a pair of adjacent screw rod assemblies, the connecting rod 412 is pressed, causing the connecting rod 412 to squeeze the extrusion rod 404 in the installation groove 402. At this time, the extrusion force is transmitted from the extrusion rod 404 to the connecting rod 405 and causes the elastic member 407 on the outer surface of the connecting rod 405 to be compressed, and the connecting rod 405 is pressed from the middle diameter section of the installation groove 402 to the small diameter section. At this time, the clamping rod 409 hinged to the fixing plate 408 is squeezed and retracted back. In the through groove 403, when the connecting block 4 is limited by the fixed block 306, the connecting rod 412 is released, the extrusion force disappears, the elastic member 2 407 prompts the fixed disk 408 to reset and makes the clamping rod 409 rotate along the fixed disk 408 and clamp into the clamping groove 307, at this time, the rotating threaded ring 410 gradually approaches and fits the fixing ring 411, so that the adjacent screw assembly is fixed again, and the fastening assembly 1 cooperates with the fastening assembly 2 to realize the relative fixation of the screw in both directions, forming a double fastening mechanism. This design greatly enhances the stability and reliability of the connection, and can maintain the stability of the connection even under harsh working conditions such as vibration and impact. Through the precise cooperation of the connecting rod 412, the extrusion rod 404, the connecting rod 405, the elastic member 2 407, the clamping rod 409, the clamping groove 307 and the threaded ring 410, the multi-point locking and fastening of the screw assembly is realized. This multi-point locking mechanism effectively prevents the screw assembly from loosening and falling off during long-term use. Through multi-point locking and tightening mechanisms, the screw assembly can be more uniform and stable when subjected to force. This helps reduce material fatigue and damage caused by uneven force, thereby improving the overall performance and life of the equipment.
