Description

Technical Field

[0001] This utility model relates to the field of pellet mill equipment technology, and in particular to a ring die fixing structure for a ring die pellet mill that is easy to disassemble and maintain. Background Technology

[0002] The ring die fixing structure for ring die pellet mills, which is easy to disassemble and maintain, is a core connecting component specifically adapted to ring die pellet mills. It is widely used in feed processing, biomass energy, and organic fertilizer pelleting. It is indispensable in pellet processing scenarios of different scales, from small and medium-sized family workshops to large-scale factory production lines, and can significantly shorten equipment downtime for maintenance.

[0003] Traditional ring die pellet mill ring die fixing structures, which are easy to disassemble and maintain, mainly consist of an annular pressure plate, fastening bolts, positioning pins, a support flange, and a lock nut. The ring die is fitted onto the positioning boss of the support flange, the annular pressure plate is covered on the end face of the ring die, the fastening bolts pass through the bolt holes of the pressure plate and the support flange, and the lock nut is tightened to complete the fixation. In the narrow installation position of the pellet mill, the bolts are affected by the high-frequency vibration of the pellet mill, resulting in stripping and rusting. The fit clearance between the positioning pin and the ring die pin hole increases due to wear, causing radial runout of the ring die during operation, which affects the pellet forming accuracy.

[0004] To address the issues of loose bolts and insufficient positioning accuracy in traditional structures, existing technologies have improved the ring die fixing structure by replacing ordinary fastening bolts with anti-loosening bolts to enhance the vibration resistance of the bolt connection. Rubber sealing gaskets are added to the mating surfaces of the support flange and the ring die, reducing the clearance between the locating pin and the pin hole. When replacing a worn ring die, operators must first use a wrench to disassemble the anti-loosening bolts one by one. Due to the significant friction between the spring washer of the anti-loosening bolt and the bolt and pressure plate, and the long-term vibration causing the bolt to seize with the threaded hole, greater external force is required for disassembly. While the reduced clearance between the locating pin and the pin hole improves positioning accuracy, it also leads to jamming on the inner wall of the pin hole and the surface of the locating pin due to dust accumulation and slight corrosion, requiring the use of a copper rod to tap the locating pin to remove it. Existing technologies only focus on optimizing anti-loosening and positioning functions, relying excessively on the rigid fit between the bolt and the locating pin, without designing a structure for quick release of constraints. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ring die fixing structure for ring die pellet mills that is easy to disassemble and maintain, aiming to improve the problems of loose bolts and insufficient positioning accuracy in the prior art.

[0008] As a further description of the above technical solution: The fixing component includes a rotating ring, which is rotatably connected to the outer wall of the annular plate, and the inner wall of the rotating ring is provided with multiple sliding grooves.

[0009] As a further description of the above technical solution: The support assembly includes multiple support blocks, each of which is fixedly connected to the outer wall of the annular plate, and each of the support blocks has a rotating groove on its top.

[0010] As a further description of the above technical solution: The bottom of the second annular plate is provided with an annular groove, and a rubber ring is fixedly connected to the inner wall of the annular groove.

[0011] As a further description of the above technical solution: The top of the second annular plate is provided with a cover plate, and the bottom front and rear sides of the cover plate are provided with positioning grooves.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the protrusion at the top of the front section of the insertion plate can initially limit the relative position of the mold and the annular plate. After the insertion plate is completely slid into the passage groove, the locking block in the receiving hole pops out under the action of the spring force and forms a locking with the bottom of the annular plate. The fixing mechanism on the outer wall of the annular plate can enhance the installation stability of the annular plate. The support mechanism provides reliable support for the overall structure, effectively improving the problem of cumbersome and time-consuming disassembly process in the prior art.

[0015] 2. In this utility model, the multiple limiting plates at the bottom of the annular plate II can constrain the mold from the top circumferential direction. The annular plate II is aligned with the fixing holes on the front and rear sides of the top of the mold. The pin slides into the fixing hole to further tighten the annular plate II to the mold, ensuring that the limiting plate continuously and stably plays a limiting role. The cooperation of the stabilizing mechanism, the annular plate II, the limiting plate and the pin can restrict the deformation of the mold from both the circumferential and axial directions, effectively ensuring the stable operation of the equipment.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 2 and Figure 6 The present invention provides an embodiment of a ring die fixing structure for a ring die pellet mill that is easy to disassemble and maintain, including a die 1. The bottom of the die 1 is provided with a quick-release mechanism 2, which is used to realize the quick disassembly and installation of the die 1. The top of the die 1 is provided with a stabilizing mechanism 3, which is used to limit the deformation of the die 1 during operation. The quick-release mechanism 2 includes multiple insertion plates 201, each fixedly connected to the bottom of the mold 1. The insertion plates 201 provide a supporting carrier for the connection between the mold 1 and the annular plate 4. Each insertion plate 201 has a protrusion 203 fixedly connected to its front top, which initially limits the relative position of the insertion plate 201 and the annular plate 4, preventing the insertion plate 201 from excessively sliding into the passage groove 204. Each insertion plate 201 has a storage hole 202 at its bottom, providing space for the installation and storage of the locking blocks 205 and springs 206. Two locking blocks 205 are slidably connected to the inner wall of each storage hole 202, engaging with the bottom of the annular plate 4 to fix the insertion plate 201 to the annular plate 4. Springs 206 are fixedly connected between each locking block 205, providing elasticity. The card block 205 is pushed out of the storage hole 202 or retracted into the storage hole 202 when pressed. The bottom of the mold 1 is provided with an annular plate 4, which is used to cooperate with the insertion plate 201 to achieve the initial positioning and fixation of the mold 1. The inner wall of the annular plate 4 is provided with multiple passage grooves 204, which are used to provide sliding channels for the insertion plate 201 to ensure that the insertion plate 201 can accurately cooperate with the annular plate 4. The inner walls of the multiple passage grooves 204 are slidably connected to the corresponding insertion plates 201. The outer wall of the annular plate 4 is provided with a fixing component 207, which is used to fix the annular plate 4 on the pellet mill frame to enhance the installation stability of the annular plate 4. The outer wall of the annular plate 4 is provided with multiple support components 208, which are used to provide support force for the annular plate 4 to prevent the annular plate 4 from tilting or displacing when the mold 1 is working. Specifically, the quick-release mechanism 2 at the bottom of mold 1 cooperates with the stabilizing mechanism 3 at the top. The quick-release mechanism 2 enables quick disassembly and installation of mold 1, while the stabilizing mechanism 3 limits the deformation of mold 1 during operation, jointly ensuring the effectiveness of mold 1. In the quick-release mechanism 2, the insertion plate 201 is fixed to the bottom of mold 1, providing a supporting carrier for the connection between mold 1 and annular plate 4. The protrusion 203 at the top of the front section of the insertion plate 201 cooperates with annular plate 4 to initially limit the relative position of the insertion plate 201 and annular plate 4, preventing the insertion plate 201 from sliding excessively into the passage groove 204. The storage hole 202 at the bottom of the insertion plate 201 provides installation and storage space for the locking block 205 and spring 206. The locking block 205 on the inner wall of the storage hole 202 engages with the bottom of annular plate 4. The insertion plate 201 is fixed to the annular plate 4. The spring 206 between the locking blocks 205 provides elastic force to the locking blocks 205, pushing them out of the storage hole 202 or retracting them into the storage hole 202 when pressed. The annular plate 4 and the insertion plate 201 cooperate to achieve the initial positioning and fixation of the mold 1. The passage groove 204 on the inner wall of the annular plate 4 provides a sliding channel for the insertion plate 201, ensuring that the insertion plate 201 accurately cooperates with the annular plate 4. The fixing component 207 on the outer wall of the annular plate 4 fixes the annular plate 4 to the pellet mill frame, enhancing the installation stability of the annular plate 4. The support component 208 on the outer wall of the annular plate 4 provides support force to the annular plate 4, preventing the annular plate 4 from tilting or shifting when the mold 1 is working.

[0020] Reference Figure 3 , Figure 4 and Figure 5 The stabilizing mechanism 3 includes a second annular plate 301, which provides an mounting carrier for the limiting plate 302 and cooperates with the mold 1 to enhance the structural strength of the top of the mold 1. The second annular plate 301 is located on the top of the mold 1, and the connection method ensures that the second annular plate 301 moves synchronously with the mold 1, avoiding relative displacement between the two from affecting the stabilizing effect. Multiple limiting plates 302 are fixedly connected to the bottom of the second annular plate 301. The multiple limiting plates 302 are used to constrain the mold 1 circumferentially, limiting the movement of the mold 1 during operation. To prevent radial deformation, the annular plate 301 and the mold 1 are provided with fixing holes 303 on the front and rear sides of the top. The fixing holes 303 are used to provide an insertion channel for the pin 304, ensuring that the pin 304 can accurately connect the annular plate 301 and the mold 1. The inner walls of the two fixing holes 303 are slidably connected with the pin 304. The pin 304 is used to further tighten the annular plate 301 and the mold 1, preventing the annular plate 301 and the mold 1 from separating under vibration, and ensuring that the limiting plate 302 continues to play a deformation limiting role. Specifically, in the stabilizing mechanism 3, the second annular plate 301 is fixedly connected to the top of the mold 1. The connection method ensures that the second annular plate 301 moves synchronously with the mold 1, avoiding the impact of relative displacement on the stabilizing effect. The second annular plate 301 provides an installation carrier for the limiting plate 302, and at the same time, it works with the mold 1 to enhance the structural strength of the top of the mold 1. Multiple limiting plates 302 fixedly connected to the bottom of the second annular plate 301 constrain the mold 1 from the circumference, limiting the radial deformation of the mold 1 during operation. The fixing holes 303 opened on the front and rear sides of the top of the second annular plate 301 and the mold 1 provide an insertion channel for the pin 304, ensuring that the pin 304 accurately connects the second annular plate 301 and the mold 1. The pin 304 slidably connected to the inner wall of the fixing hole 303 further tightens the second annular plate 301 and the mold 1, preventing the two from separating under vibration, thereby ensuring that the limiting plate 302 continues to play a deformation limiting role. The cooperation of each component achieves effective limitation of the deformation of the mold 1, ensuring the stability of the mold 1 during operation.

[0021] Reference Figure 3 , Figure 5 and Figure 6 The fixing component 207 includes a rotating ring 2071, which is used to adjust the fit with the external structure to fix or loosen the annular plate 4. The rotating ring 2071 is rotatably connected to the outer wall of the annular plate 4. The rotatable connection ensures that the rotating ring 2071 can be flexibly adjusted without affecting the fixing stability of the annular plate 4. The inner wall of the rotating ring 2071 has multiple sliding grooves 2072, which provide sliding channels for external positioning components, allowing the external positioning components to move along the sliding grooves 2072, thereby achieving precise positioning and fixing of the rotating ring 2071. The supporting component 208 includes multiple support blocks 2081, which provide radial support force for the annular plate 4, enhancing the structural stability of the annular plate 4. All of the multiple support blocks 2081 are connected to the annular plate 4. The outer wall of the first 4 is fixedly connected. The fixed connection method ensures that the support block 2081 and the annular plate 4 are subjected to force synchronously, avoiding the support block 2081 from loosening and causing support failure. The top of each of the multiple support blocks 2081 is provided with a rotating groove 2082. The rotating groove 2082 is used to provide rotation space for the external support component, so that the external support component can rotate flexibly in the rotating groove 2082 to adapt to the support requirements under different installation scenarios. The bottom of the second annular plate 301 is provided with an annular groove 9. The annular groove 9 is used to provide installation space for the rubber ring 10, ensuring that the rubber ring 10 can be stably fixed at the bottom of the second annular plate 301. The inner wall of the annular groove 9 is fixedly connected with the rubber ring 10. The rubber ring 10 is used to fill the gap between the second annular plate 301 and the top of the mold 1, enhance the sealing of the connection between the two, and absorb vibration to avoid rigid collisions that cause component wear. Specifically, in the fixing component 207, the rotating ring 2071 is rotatably connected to the outer wall of the annular plate 4. This connection ensures that the rotating ring 2071 can be flexibly adjusted without affecting the stability of the annular plate 4. The rotation adjustment of the rotating ring 2071, in coordination with the external structure, allows the annular plate 4 to be fixed or released. The sliding groove 2072 on the inner wall of the rotating ring 2071 provides a sliding channel for the external positioning component, allowing the external positioning component to move along the sliding groove 2072 to achieve precise positioning and fixing of the rotating ring 2071. In the supporting component 208, multiple support blocks 2081 are fixedly connected to the outer wall of the annular plate 4. This connection ensures that the support blocks 2081 and the annular plate 4 are subjected to force synchronously to avoid support failure. The support blocks 2081 are part of the annular plate 4. The radial support force enhances the structural stability. The rotating groove 2082 at the top of the support block 2081 provides rotation space for the external support components, allowing them to rotate flexibly within the rotating groove 2082 to adapt to different installation scenarios. The annular groove 9 at the bottom of the annular plate 2 301 provides installation space for the rubber ring 10 to ensure its stable fixation. The rubber ring 10 on the inner wall of the annular groove 9 fills the gap between the annular plate 2 301 and the top of the mold 1, enhancing the sealing of the connection between the two while absorbing vibration and avoiding rigid collisions that could cause component wear. The cooperation of each component achieves flexible fixation and stable support for the annular plate 1 4, as well as sealing and vibration reduction between the annular plate 2 301 and the mold 1, jointly ensuring the installation stability and operational reliability of the entire ring mold fixing structure.

[0022] Reference Figure 1 , Figure 3 and Figure 5 The top of the annular plate 301 is provided with a cover plate 5, which covers the top of the annular plate 301 and the top of the pin 304 to prevent dust from entering the fixing hole 303 and affecting the sliding of the pin 304. Positioning grooves 8 are provided on the front and rear sides of the bottom of the cover plate 5. The positioning grooves 8 are used to precisely engage with the top of the pin 304 to ensure that the cover plate 5 can be quickly aligned during installation. The two positioning grooves 8 are slidably connected to the top of the corresponding pin 304. This sliding connection facilitates quick installation and removal of the cover plate 5 and restricts its lateral displacement. Pull blocks 6 are fixedly connected to the left and right sides of the top of the cover plate 5. The pull blocks 6 provide mounting points for the pull rod 7. Meanwhile, it is convenient for operators to grab and disassemble the cover plate 5. A pull rod 7 is rotatably connected between the two pull blocks 6. The pull rod 7 can rotate around the pull block 6. The operator can easily move the cover plate 5 by pulling the pull rod 7, reducing the degree of disassembly and assembly of the cover plate 5. A locking block 11 is fixedly connected to the adjacent side of the annular plate 301 and the cover plate 5. The locking block 11 is used to provide the installation and cooperation base for the locking buckle 12, realizing the locking connection between the annular plate 301 and the cover plate 5. Locking buckles 12 are slidably connected between multiple locking blocks 11. The sliding cooperation between the locking buckle 12 and the locking block 11 can quickly lock or unlock the annular plate 301 and the cover plate 5, preventing the cover plate 5 from accidentally falling off during equipment operation. Specifically, the cover plate 5 at the top of the annular plate 301 covers the top of the annular plate 301 and the top of the pin 304 to prevent dust from entering the fixing hole 303 and affecting the sliding of the pin 304; the positioning grooves 8 on the front and rear sides of the bottom of the cover plate 5 precisely match the top of the pin 304 to ensure that the cover plate 5 can be quickly aligned during installation. The positioning grooves 8 are slidably connected to the top of the pin 304, which facilitates the quick installation and removal of the cover plate 5 and restricts the lateral displacement of the cover plate 5; the pull blocks 6 on the left and right sides of the top of the cover plate 5 provide installation fulcrums for the pull rod 7, and at the same time facilitate the operator to grab and remove the cover plate 5. The pull rod 7 between the two pull blocks 6 can rotate around the pull blocks 6, and the operator can lift it. Pull rod 7 can easily move cover plate 5, reducing the degree of disassembly and assembly of cover plate 5; the locking block 11 on the side of the annular plate 2 301 adjacent to cover plate 5 provides the mounting and mating base for the latch 12, realizing the locking connection between annular plate 2 301 and cover plate 5. The locking block 11 and latch 12 slide together, which can quickly lock or unlock annular plate 2 301 and cover plate 5, preventing cover plate 5 from accidentally falling off during equipment operation; the cooperation of each component realizes the accurate positioning, quick disassembly and assembly and reliable locking of cover plate 5, which not only protects the pin 304 from dust, but also improves the ease of operation and safety of use of cover plate 5, and further enhances the overall reliability of the stabilizing mechanism.

[0023] Working principle: When installing mold 1, the fixing component 207 on the outer wall of the annular plate 4 first securely fixes the annular plate 4 to the pellet mill frame. Simultaneously, multiple support components 208 on the outer wall of the annular plate 4 provide uniform support force to prevent tilting during subsequent assembly. Then, the operator holds mold 1 and aligns the multiple insertion plates 201 fixed at the bottom of mold 1 with the multiple passage slots 204 opened on the inner wall of the annular plate 4, pushing them axially along the passage slots 204. During this process, the front section of the insertion plate 201... The top protrusion 203 can slide against the inner wall of the passage groove 204 in real time. When the protrusion 203 reaches the end of the passage groove 204, it will produce a slight obstruction, indicating that the insertion plate 201 has slid into the preset depth, avoiding over-insertion that may cause subsequent locking failure. After the insertion plate 201 is fully slid into the passage groove 204, the two locking blocks 205 in the bottom storage hole 202 of the insertion plate 201 will pop out of the storage hole 202 and open outward under the elastic force of the spring 206, and finally lock into the bottom end face of the annular plate 4. The locking blocks 205 and the annular plate 4 are locked together. The annular plate 4 forms an axial limit, which, together with the radial constraint of the protrusion 203, enables the mold 1 to be quickly fixed to the annular plate 4. The entire installation process does not require special tools such as wrenches and screwdrivers, greatly reducing the time spent in the traditional installation process. When it is necessary to replace the mold 1, the operator does not need to disassemble the fixing component 207 and the support component 208 of the annular plate 4. He only needs to press the two locking blocks 205 at the bottom of the annular plate 4 with his fingers or a simple tool, so that the locking blocks 205 retract into the receiving hole 202 to overcome the elastic force of the spring 206, thus releasing the locking blocks 205 from the annular plate 4. The clamping constraint of plate 4 allows the mold 1 to be pulled outward along the axial direction of the passage groove 204, thereby pulling the insertion plate 201 out of the passage groove 204 and completing the disassembly of the mold 1. Compared with the cumbersome process of replacing the mold 1 by disassembling bolts and nuts one by one in the prior art, the guiding fit between the insertion plate 201 and the passage groove 204 and the elastic clamping between the clamping block 205 and the spring 206 in this structure enable the quick assembly and disassembly of the mold 1, effectively solving the problem that the prior art cannot quickly replace the mold 1 and significantly improving the maintenance efficiency of the ring die pellet mill. In stabilizing mechanism 3, the second annular plate 301 is fixedly connected to the top of mold 1. This connection ensures that the second annular plate 301 moves synchronously with mold 1, preventing relative displacement from affecting the stabilizing effect. Multiple limiting plates 302 are fixedly connected to the bottom of the second annular plate 301, constraining mold 1 circumferentially and limiting its radial deformation during operation. Fixing holes 303 on the front and rear sides of the top of the second annular plate 301 and mold 1 provide insertion channels for the pin 304, ensuring precise engagement of the pin 304 with the second annular plate 301 and mold 1. The pin 304, which is slidably connected to the inner wall of the fixed hole 303, further secures the annular plate 301 to the mold 1, preventing them from separating under equipment vibration. The components work together to form a dual stable structure with fixed connection, circumferential constraint, and axial fastening. The fixed connection between the annular plate 301 and the mold 1 enhances the structural strength of the top of the mold 1. The radial deformation of the mold 1 is limited by the limiting plate 302. The cooperation between the pin 304 and the fixed hole 303 ensures the reliability of the connection and effectively controls the deformation of the mold 1 during operation, ensuring the stability of the mold 1 during operation.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make substitutions for some of the technical features.
