Description

Technical Field

[0001] This invention belongs to the field of feed ingredient production technology, and in particular relates to a feed ingredient production line. Background Technology

[0002] Feed ingredients are made by physically crushing the high-fiber and lignin-containing wood. They are used in animal feed to increase fecal volume, dilute intestinal contents, stabilize blood sugar, and promote intestinal peristalsis, thereby improving the efficiency of nutrient digestion and absorption. Existing technologies also use sapwood and scraps. However, traditional processes often directly process wood chips and low-quality moldy bamboo, resulting in small-sized and simple-to-assemble processing machines. The finished products have high moisture and impurity content, and the chips are easy to scatter and splash, making the production site environment poor.

[0003] This production line and process are more suitable for whole timbers, as the timbers are larger in volume and contain more lignin and fiber, resulting in a significantly higher quality product compared to scraps.

[0004] The production of feed raw materials involves various equipment, such as clamping equipment, cutting equipment, crushing equipment, fiber separation equipment, mixing equipment, and drying equipment. In the current technology, in order to improve production efficiency, multiple sets of equipment are combined into a complete production line to ensure that each process can be connected to each other, and the wood produced in each process can be directly transferred to the next process, thereby improving production efficiency. However, after the overall production line is formed, the wood is continuously supplied by the clamping equipment or feeding equipment at the beginning, so it will not stop arbitrarily. After continuous feeding, the wood will be continuously fed to the crushing equipment for crushing.

[0005] In existing production line crushing devices, to accommodate wood of different specifications or at different heights and orientations, the front end of the crushing device is equipped with a movable extrusion roller that can move up and down adaptively according to the size of the object while extruding. The rear end uses a combination of cutting components and a filter screen to pass wood cut smaller than the filter screen opening through the filter screen into the next process. Wood that cannot pass through is crushed and then enters the filter screen. However, with the continuous input of wood, occasionally incompletely crushed wood will accumulate inside the crushing device, causing crushing blockage. Therefore, a new solution is proposed. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a feed raw material production line to solve the above problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a feed ingredient production line, the structure of which includes: a peeling device, a cutting device, a crushing device, and a drying device.

[0008] Preferably, the crushing device includes a housing, a first pressure roller, a second pressure roller, and an adjustable crushing assembly;

[0009] The crushing device also includes a shell, a first pressure roller, a second pressure roller, and an adjustable crushing assembly;

[0010] The outer shell has a crushing chamber inside, and a feed opening communicating with the crushing chamber is opened at the rear of the outer shell. The first and second pressure rollers are arranged in a vertically mirror image. The left and right ends of the first and second pressure rollers are axially connected to the inner wall of the feed opening, and the first pressure roller is located directly above the second pressure roller. The adjustable crushing assembly includes a first support plate, a second support plate, a third pressure roller, a fourth pressure roller, a fifth pressure roller, and a radial adjustment module. The first and second support plates have three radially distributed straight grooves. The third, fourth, and fifth pressure rollers are arranged in a triangle and their left and right ends are axially movable within the straight grooves.

[0011] A radial adjustment module is installed on the outside of the first and second bearing plates. The radial adjustment module includes a radial transmission block, a first transmission gear, and a first radial adjustment gear. The first transmission gear is axially movably installed on the radial transmission block facing the center of the first and second bearing plates. The first radial adjustment gear is axially rotatably connected to the outer side of the first and second bearing plates. The end face of the first radial adjustment gear has three sections of adjustable arc surfaces with successively varying heights along the circumferential direction.

[0012] The first and second bearing plates are provided with limiting grooves that match the position of the straight groove opening. A radial transmission block is radially movably installed in the limiting groove. The left and right ends of the third, fourth, and fifth pressure rollers are axially connected to the corresponding radial transmission blocks through rotating shafts.

[0013] When the first radial adjustment gear rotates, the adjustment arc surface of its end face meshes with the first transmission gear. The change in the height of the arc surface drives the first transmission gear to rotate. Because the radial transmission block is constrained by the limiting slide groove, the rotation of the first transmission gear is converted into the radial movement of the radial transmission block along the limiting slide groove, which in turn drives the third pressure roller, the fourth pressure roller, and the fifth pressure roller to perform radial adjustment synchronously along the straight groove.

[0014] Preferably, the radial adjustment module further includes a second radial adjustment gear, a second transmission gear, and a radial displacement motor;

[0015] The adjustment arc surface corresponds to the position of a single radial transmission block, and the height of the adjustment arc surface decreases in a stepwise manner from near the center to away from the center. The first transmission gear meshes with the edge teeth of the adjustment arc surface of the first radial adjustment gear disk.

[0016] Preferably, the outer side of the first radial adjustment toothed disk is axially rotatably connected to the second radial adjustment toothed disk, and the first radial adjustment toothed disk and the second radial adjustment toothed disk are of different structures.

[0017] The inner ring of the second radial adjustment gear disk is provided with a stepped adjustment arc surface that matches the curvature of the outer ring of the first radial adjustment gear disk and the height of the arc surface changes in the same way. A clamping space is formed between the first radial adjustment gear disk and the second radial adjustment gear disk. The first transmission gear is axially limited and installed in the clamping space and simultaneously meshes with the teeth of the arc surfaces on both sides.

[0018] Preferably, the outer ring of the second radial adjustment gear is integrally formed with continuous tooth grooves, and the outer rings of the first bearing plate and the second bearing plate are axially rotatably mounted with a second transmission gear, which meshes with the continuous tooth grooves of the outer ring of the second radial adjustment gear.

[0019] A radial displacement motor is installed on the outside of the first and second bearing plates. The output shaft of the radial displacement motor is connected to the second transmission gear. The radial displacement motor drives the second transmission gear to rotate, which can synchronously drive the first and second radial adjustment gears to rotate. Then, the transmission gear clamped in the middle drives the radial transmission block to move closer to or away from the axis along the limiting slide groove. The first and second bearing plates are arranged opposite each other on the left and right, and the first and second radial adjustment gears, the second transmission gear, and the radial displacement motor on the outer side are all the same and symmetrically arranged.

[0020] Preferably, a transmission module is installed on the outer side of the second bearing plate, located on the outer side of the first radial adjusting gear disk. The transmission module includes a drive gear, a transition gear, an internal meshing gear ring, and a variable transmission assembly.

[0021] The drive gear is welded and installed on the outer end of the drive spindle. A transition gear is axially meshed in front of the drive gear. The outer end of the transition gear is axially connected to the inner ring teeth of the inner meshing gear ring, and both the drive gear and the transition gear are located in the inner ring of the inner meshing gear ring.

[0022] Variable transmission components are provided on the drive shafts of the third, fourth, and fifth pressure rollers at positions parallel to the drive gear.

[0023] Preferably, the variable transmission assembly includes a secondary drive gear, a fastening gear, a moving meshing gear, a first support shaft, a second support shaft, and a meshing compression spring;

[0024] The auxiliary gear is welded and installed on the drive shaft of the third, fourth and fifth pressure rollers, and is parallel to the drive gear. A fastening gear is axially connected to the rear of the auxiliary gear. A first support shaft is welded and installed on the connecting shaft of the fastening gear. A second support shaft is axially movably connected to the end of the first support shaft away from the fastening gear.

[0025] The movable meshing gear is axially movably installed at the end of the second support shaft away from the first support shaft, and the transmission shaft is correspondingly adapted to the second support shaft. The movable meshing gear meshes with both the fastening gear and the outer ring of the inner meshing gear ring.

[0026] The engagement spring is sleeved on the outside of the drive shaft of the fastening gear and the drive shaft of the moving engagement gear, and the engagement spring can continuously apply pressure to the drive shaft of the moving engagement gear;

[0027] The axial angle of the first support shaft is fixed. When the third, fourth, and fifth pressure rollers move radially, the second support shaft swings adaptively with the connection end of the first support shaft as the axis. The elastic force of the meshing spring always applies axial force to the moving meshing gear, ensuring that it maintains stable meshing with the fastening gear and the outer ring of the inner meshing gear ring.

[0028] Preferably, a first oil cap is installed on the outer side of the first bearing plate by fastening bolts, and a second oil cap is installed on the outer side of the second bearing plate by fastening bolts.

[0029] The fastening gear is axially movably installed on the inner side of the second oil sealing cover. The inner side of the second oil sealing cover is provided with a moving limiting groove that matches the axial moving direction of the moving meshing gear. The moving meshing gear is axially connected to and limited in the moving limiting groove.

[0030] Both the first and second oil sealing caps have oil inlets on their sides, and oil sealing caps are screwed onto the oil inlets.

[0031] Preferably, the rollers of the first, second, third, fourth and fifth pressure rollers are circumferentially distributed with rolling teeth, and the inner wall of the rolling cavity is provided with a relief tooth groove that is offset from the position of the rolling teeth. The rolling teeth and the relief tooth groove together form an alternating rolling structure.

[0032] A clearance block is provided in the gap between the third, fourth and fifth pressure rollers, and the first and second bearing plates and the clearance block are an integral structure.

[0033] The chip removal modules are all installed on the outer side of the clearance block at positions that are spaced apart from the third and fourth pressure rollers, the fourth and fifth pressure rollers, and the fifth and third pressure rollers by bolts.

[0034] Preferably, the chip removal module includes a top cover, an inclined bar, a square spring, a first limiting square rod, and a second limiting square rod. The first limiting square rod is fastened to the clearance block by bolts, and the inclined bar is movably installed in the first limiting square rod. The front of the inclined bar is provided with a raised groove scraping structure that matches the rolling teeth.

[0035] The inclined bars are arranged radially symmetrically with the first limiting bar and are symmetrically arranged vertically, each corresponding to the adjacent cleaning pressure roller.

[0036] Both the first and second limiting rods are connected to the inclined bars on both sides. The square spring is sleeved on the outside of the second limiting rod and can continuously apply an outward elastic thrust to the inclined bars. A top cover is fastened to the top of the first limiting rod by bolts.

[0037] Preferably, a discharge port is provided directly below the compaction chamber, and the third, fourth, and fifth pressure rollers, as well as the first and second bearing plates, all rotate in a counterclockwise direction.

[0038] A conveyor belt is located directly below the crushing chamber, and the material discharged from the outlet falls directly onto the conveyor belt; a secondary drive motor is located to the right of the first and second pressure rollers. The secondary drive motor is located on the side of the shaft of the second pressure roller, and its output shaft is connected to the drive shaft of the first and second pressure rollers through a belt, which can drive the two pressure rollers to rotate synchronously.

[0039] A motor bracket is provided on the right side of the outer casing. A main drive motor is installed on the top of the motor bracket, corresponding to the axial position of the first and second bearing plates. The main drive motor can drive the first bearing plate, the second bearing plate, and the integrated clearance block to achieve axial rotation transmission synchronously.

[0040] The crushing device is connected to the cutting device via a conveyor belt at its rear. A conveyor roller is located to the right of the cutting device, and a peeling device is located directly behind the conveyor roller. A drying device is located in front of the conveyor belt below the crushing chamber.

[0041] The present invention provides a feed ingredient production line, which has the following advantages:

[0042] 1. This invention achieves synchronous and precise radial adjustment of the third, fourth, and fifth pressure rollers by employing a radial adjustment module composed of a first radial adjustment toothed disc, a second radial adjustment toothed disc, a first transmission gear, a second transmission gear, and a radial displacement motor. The first and second radial adjustment toothed discs form a clamping space, limiting the first transmission gear within it and engaging with the toothed adjustment arc surfaces on both sides. When the radial displacement motor drives the second transmission gear to rotate, it can drive the two toothed discs to rotate synchronously, causing the adjustment arc surfaces to drive the first transmission gear to rotate through the teeth, thereby driving the radial transmission block to move along the limiting slide groove, ultimately achieving synchronous approach or departure of the third, fourth, and fifth pressure rollers from the axis. This adjustment structure, combined with the staggered crushing structure of the pressure rollers and the inner wall of the crushing chamber, allows for flexible adjustment of the crushing gap according to the hardness, moisture, and other characteristics of the wood raw material, thereby improving the uniformity of wood fiber crushing and meeting the fiber particle size requirements of different feeding scenarios.

[0043] 2. This invention, by setting up a variable transmission assembly with a first support shaft, a second support shaft, a meshing spring, and a moving meshing gear, enables adaptive oscillation when the pressure roller moves radially. In conjunction with the meshing spring, it continuously applies axial thrust to the moving meshing gear, ensuring that it is always stably engaged with the fastening gear and the internal meshing gear ring when the pressure roller position changes. This achieves adaptive adjustment of the transmission path as the position changes, effectively avoiding transmission jamming and power loss during adjustment in traditional equipment.

[0044] 3. This invention configures a chip removal module consisting of a top cover, an inclined bar, a square spring, a first limiting bar, and a second limiting bar at the gap between the pressure rollers. The thrust of the square spring causes the front end of the inclined bar to adapt to the raised groove scraping structure that matches the pressing teeth as the pressure roller moves radially, thus accurately cleaning the wood chips between the teeth. Combined with the avoidance block formed by the first and second bearing plates, it can prevent the accumulation of raw materials in the gap between the pressure rollers and reduce downtime maintenance caused by debris blockage.

[0045] 4. This invention employs a transmission structure driven by a single main motor, combined with a closed protective space formed by the first and second oil seals. The power of the main motor is transmitted in stages through components such as couplings and transmission modules. This not only drives the bearing plate and pressure roller to achieve coordinated revolution and rotation, but also reduces friction between gears and transmission components through quantitative lubrication in the closed space. This simplifies the transmission structure, reduces energy consumption, and extends the service life of the equipment. Attached Figure Description

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0063] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0064] Existing crushing devices of this type suffer from several drawbacks in controlling the size of crushed materials. These include complex roller spacing adjustment structures, cumbersome operation procedures, and limited adjustment precision. Repeated adjustments also reduce production efficiency, and the adjustment process can lead to problems such as transmission system jamming and power loss. Furthermore, the numerous internal gaps in existing crushing devices allow debris generated during crushing to easily become trapped in the gaps between the rollers and the frame, as well as at the connections of transmission components, increasing maintenance costs and hindering raw material flow, thus reducing overall crushing efficiency. Therefore, to address these issues, this paper proposes the following technical solution: To resolve the problems of complex roller spacing adjustment, cumbersome operation, and limited adjustment precision in existing crushing devices... In addition to the problems of easy jamming and high power loss in the transmission system, as well as the accumulation of debris, high maintenance costs, and low crushing efficiency caused by numerous internal gaps, the technical solution proposed in this case is as follows: The crushing device 2 adopts a progressive crushing structure. The first pressure roller 22 and the second pressure roller 23, which are arranged in parallel at the top and bottom, are configured at the feed opening 212 to perform the first compression crushing treatment on the incoming wood raw material and complete the preliminary crushing and shaping. The core crushing area inside the device is composed of a symmetrical mounting base formed by the first bearing plate 241a and the second bearing plate 241b. The third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c, which are arranged in an equilateral triangle, are mounted on the base through a radial movable structure to form a three-dimensional crushing.

[0065] The transmission structure of the main motor single-source drive: The main drive motor 6 is rigidly connected to the central shaft of the first bearing plate 241a and the second bearing plate 241b through a coupling, driving the first bearing plate 241a and the second bearing plate 241b to rotate counterclockwise synchronously, which in turn drives the triangularly distributed third pressure roller 242a, fourth pressure roller 242b, and fifth pressure roller 242c to rotate counterclockwise around the axis; at the same time, the main motor power is transmitted to the transmission module 244 for secondary transmission, driving the internal meshing gear ring 24 through the drive gear 2441 and the transition gear 2442. 43 rotates, and then the variable transmission component 2444 transmits the power to the transmission shafts of each pressure roller, so that the third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c rotate on their own axis while revolving around the center. This synchronous motion of revolution and rotation, combined with the interlacing shearing action of the grinding protrusions 242c1 on the surface of the pressure roller and the avoidance grooves 213 on the inner wall of the grinding cavity 211, forms a multi-dimensional, high-frequency grinding contact, realizing the fine crushing of wood raw materials and improving the uniformity of crushing. In order to achieve the adjustment of the roller spacing;

[0066] Radial adjustment module 243 implementation description: The first radial adjustment toothed disc 2433 and the second radial adjustment toothed disc 2434 form a clamping space, which limits the first transmission gear 2432 and meshes with the toothed adjustment arc surfaces 24331 on both sides. The radial transfer motor 2436 drives the second transmission gear 2435, which drives the two toothed discs to rotate synchronously. The adjustment arc surfaces 24331 drive the transmission gear to rotate through the teeth, which in turn drives the radial transmission block 2431 to move along the limiting slide groove 241b2, so that the three pressure rollers move synchronously closer to or further away from the shaft center, and the operation is automated.

[0067] Description of the continuous force transmission structure adaptable to radial movement of the pressure rollers: To address the power transmission requirements of the third pressure roller 242a, fourth pressure roller 242b, and fifth pressure roller 242c during radial adjustment, a variable transmission assembly 2444 is provided. This assembly forms a swingable structure through a hinged connection between the first support shaft 24444 and the second support shaft 24445. This, in conjunction with the meshing spring 24446, applies a continuous axial thrust to the moving meshing gear 24443. When the pressure rollers move radially to adjust their position, the support shafts swing synchronously to adapt to the transmission angle. The degree of change, while the spring force ensures that the moving meshing gear 24443 is always stably meshed with the fastening gear 24442 and the inner meshing gear ring 2443. Thus, when the radial position of the transmission shaft of the third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c is adjusted (when the machine is paused), the adaptive swing of the support shaft and the spring force of the meshing spring 24446 ensure that the moving meshing gear 24443 is always stably meshed with the corresponding gear, thus ensuring the continuity of power transmission before and after adjustment and during adjustment.

[0068] The chip removal module 4 is designed to address the chip accumulation problem during the rolling process. To solve the chip accumulation problem, a chip removal module 4 is installed at the gap between the pressure rollers. The front end of the inclined bar 42 is provided with a raised groove removal structure 421 that is adapted to the rolling teeth 242c1. The square spring 43 pushes it to move radially with the pressure roller and adaptively fit the roller surface to clean the wood chips between the teeth. The top cover 41 protects the internal components from impurities, reduces maintenance costs and ensures smooth material flow.

[0069] The design of the oil sealing cap protection and lubrication structure of the transmission components: The oil sealing cap is installed on the outside of the bearing plate to form a closed space. An oil inlet 3a1 with a sealing screw cap is opened on the side, which can be filled with no more than one-quarter of the internal space of lubricating oil, reducing the friction between the gear and the transmission components. It works in conjunction with the moving limit groove 3b1 to ensure stable gear movement and reduce wear and impurity intrusion.

[0070] The overall system drive and continuous conveying design: The whole system drives the bearing plate and the feed roller through the main drive motor 6 and the secondary drive motor 5 respectively. The crushed material is discharged through the lower discharge port 214 to the conveyor belt 1c and directly conveyed to the drying device 1b, realizing the full-process automation from raw material processing to finished product processing.

[0071] Please see Figures 1 to 6 This invention provides a technical solution for a feed ingredient production line, the structure of which includes: a peeling device 1, a cutting device 1a, a crushing device 2, and a drying device 1b.

[0072] The crushing device 2 includes a housing 21, a first pressure roller 22, a second pressure roller 23, and an adjustable crushing assembly 24. The crushing device 2 also includes a housing 21, a first pressure roller 22, a second pressure roller 23, and an adjustable crushing assembly 24. A crushing chamber 211 is formed inside the housing 21, and a feed opening 212 communicating with the crushing chamber 211 is formed at the rear of the housing 21. The first pressure roller 22 and the second pressure roller 23 are arranged in a vertically mirror image, with their left and right ends axially connected to the inner wall of the feed opening 212. The first pressure roller 22 is located directly above the second pressure roller 23. The adjustable crushing assembly 24 includes a first support plate 241a, a second support plate 241b, a third pressure roller 242a, and a fourth pressure roller 242b. The fifth pressure roller 242c and the radial adjustment module 243 are provided. Three radially distributed straight grooves 241b1 are formed on the first support plate 241a and the second support plate 241b. The third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c are arranged in a triangle, with their left and right ends axially movable within the straight grooves 241b1. A radial adjustment module 243 is installed outside the first support plate 241a and the second support plate 241b. The radial adjustment module 243 includes a radial transmission block 2431, a first transmission gear 2432, and a first radial adjustment gear disc 2433. The first transmission gear 241b2 is axially mounted on the radial transmission block 2431 facing the center of the first support plate 241a and the second support plate 241b. 32. A first radial adjusting gear 2433 is axially rotatably connected to the outward side of the first bearing plate 241a and the second bearing plate 241b. The end face of the first radial adjusting gear 2433 has three sections of adjusting arc surface 24331 with successively varying heights along the circumferential direction. The first bearing plate 241a and the second bearing plate 241b are provided with limiting grooves 241b2 that match the position of the straight groove 241b1. A radial transmission block 2431 is radially movably installed in the limiting groove 241b2. The left and right ends of the third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c are respectively axially connected to the corresponding radial transmission block 2431 through rotating shafts. When the first radial adjusting gear 2433 rotates, the adjusting arc surface 24331 on its end face... 331 meshes with the first transmission gear 2432, and drives the first transmission gear 2432 to rotate through the change of the arc height. Because the radial transmission block 2431 is constrained by the limiting slide groove 241b2, the rotation of the first transmission gear 2432 is converted into the radial movement of the radial transmission block 2431 along the limiting slide groove 241b2, thereby driving the third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c to synchronously perform radial adjustment along the straight groove 241b1. The feed wood fiber processing production system of the present invention takes the crushing device 2 as the core innovation. Its innovation is concentrated in the fact that the structure of the transmission gear clamped by the double radial adjustment toothed disc is used to realize the synchronous radial adjustment of the pressure rollers, which solves the problems of complex and insufficient precision of traditional roller spacing adjustment.A variable transmission assembly 2444 with an adaptive swing support shaft and meshing spring 24446 is designed to ensure continuous power transmission during the radial movement of the pressure roller, avoiding transmission jamming and loss. A chip removal module 4, which adaptively conforms to the pressure roller, automatically cleans inter-tooth debris, solving the problem of accumulated debris hindering material flow. A sealed oil cap structure and a quantitative lubrication design reduce impurity intrusion and component wear. Simultaneously, all processing stages are integrated into a continuous production line, achieving full-process automation with variable frequency drive.

[0073] The radial adjustment module 243 also includes a second radial adjustment toothed disc 2434, a second transmission gear 2435, and a radial displacement motor 2436; the adjustment arc surface 24331 corresponds to the position of a single radial transmission block 2431, and the height of the adjustment arc surface 24331 decreases in a stepwise manner from near the center to away from the center. The first transmission gear 2432 meshes with the edge teeth of the adjustment arc surface 24331 of the first radial adjustment toothed disc 2433. The outer shell 21 of the crushing device 2 provides a closed cavity for processing. The first pressure roller 22 and the second pressure roller 23 at the feed opening 212 are symmetrically distributed vertically. They perform preliminary crushing of the raw material by relative rotation. The axial positions of the two are fixed. The roller surface crushing convex teeth 242c1 cooperate with the avoidance structure of the inner wall of the feed opening 212 to ensure that the raw material enters smoothly and completes the preliminary crushing, providing pre-treated material for subsequent fine processing. Its layout design ensures smooth raw material feeding and stable preliminary crushing effect.

[0074] The outer side of the first radial adjusting gear disk 2433 is axially rotatably connected to the second radial adjusting gear disk 2434. The first radial adjusting gear disk 2433 and the second radial adjusting gear disk 2434 are of different structures. The inner ring of the second radial adjusting gear disk 2434 is provided with a stepped adjusting arc surface 24331 that matches the arc of the outer ring of the first radial adjusting gear disk 2433, and the height of the arc surface changes in a consistent manner. A clamping space is formed between the first radial adjusting gear disk 2433 and the second radial adjusting gear disk 2434. The first transmission gear 2432 is axially limited and installed in this clamping space and simultaneously meshes with the teeth of the arc surfaces on both sides. Adjustable grinding... The crushing assembly 24 is the main structure for achieving fine crushing and spacing adjustment. The first bearing plate 241a and the second bearing plate 241b serve as the supporting foundation. The straight groove 241b1 on them provides a radial movement channel for the third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c. The third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c are arranged in a triangle to form a crushing space. The radial adjustment module 243 is connected to the pressure roller shaft and drives the pressure roller to move synchronously along the straight groove 241b1 through mechanical transmission, so as to realize the flexible adjustment of the roller spacing and meet the crushing particle size requirements of different raw materials.

[0075] The outer ring of the second radial adjustment gear disk 2434 is integrally formed with continuous toothed grooves 24341. A second transmission gear 2435 is axially mounted on the outer ring of the first support plate 241a and the second support plate 241b, meshing with the continuous toothed grooves 24341 on the outer ring of the second radial adjustment gear disk 2434. A radial displacement motor 2436 is mounted outside the first support plate 241a and the second support plate 241b. The output shaft of the radial displacement motor 2436 is connected to the second transmission gear 2435. Driving the second transmission gear 2435 to rotate via the radial displacement motor 2436 synchronously drives the first radial adjustment gear disk 2433 and the second radial adjustment gear disk 2434 to rotate. This, in turn, drives the radial transmission block 2431 along the limiting slide groove 241b2 to move closer to or away from the axis via the transmission gear clamped in the middle. The first support plate 241a and the second support plate 241b move left and right... The first radial adjustment gear 2433, the second radial adjustment gear 2434, the second transmission gear 2435, and the radial movement motor 2436, arranged opposite to each other and symmetrically on the outer side, achieve pressure roller adjustment through the coordinated transmission of gears and arc surfaces. The adjustment arc surface 24331 on the end face of the first radial adjustment gear 2433 has a stepped height change and meshes with the first transmission gear 2432 at the end of the radial transmission block 2431. The radial transmission block 2431 is constrained by the limiting slide groove 241b2. When the gear 2433 rotates, the change in arc surface height drives the gear to rotate through the teeth. Due to the limitation of the slide groove, the rotation of the gear is converted into the linear movement of the radial transmission block 2431, which in turn drives the third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c to move synchronously closer to or further away from the axis, thereby achieving uniform adjustment of the roller spacing and solving the problems of complex and poor synchronization of traditional adjustment structures.

[0076] A transmission module 244 is mounted on the outer side of the second bearing plate 241b and on the outer side of the first radial adjusting gear disk 2433. The transmission module 244 includes a drive gear 2441, a transition gear 2442, an internal meshing gear ring 2443, and a variable transmission assembly 2444. The drive gear 2441 is welded to the outer end of the drive spindle. The transition gear 2442 is axially meshed in front of the drive gear 2441. The outer end of the transition gear 2442 is axially connected to the inner teeth of the internal meshing gear ring 2443, and both the drive gear 2441 and the transition gear 2442 are located within the inner ring of the internal meshing gear ring 2443. The transmission of the third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c is also described. A variable transmission assembly 2444 is arranged on the shaft parallel to the drive gear 2441. The double-tooth disc clamping structure of the radial adjustment module 243 is a key innovation. The first radial adjustment toothed disc 2433 and the second radial adjustment toothed disc 2434 form a clamping space. The first transmission gear 2432 is axially limited in it and simultaneously meshes with the arc-shaped teeth on both sides to ensure balanced transmission force. The outer ring tooth groove of the second radial adjustment toothed disc 2434 meshes with the second transmission gear 2435. When the radial transfer motor 2436 drives the gear to rotate, the double toothed discs rotate synchronously. The pressure roller is moved by the stepped arc surface. The symmetrical structure of the two bearing plates ensures the consistency of adjustment at both ends of the pressure roller, simplifies the operation steps and improves the adjustment efficiency.

[0077] The variable transmission assembly 2444 includes a secondary drive gear 24441, a fastening gear 24442, a moving meshing gear 24443, a first support shaft 24444, a second support shaft 24445, and a meshing compression spring 24446. The secondary drive gear 24441 is welded and installed on the transmission shafts of the third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c, and is parallel to the drive gear 2441. The fastening gear 24442 is axially connected to the rear of the secondary drive gear 24441, and the fastening gear 24442 is welded and mounted on the connecting shaft of the fastening gear 24442. A first support shaft 24444 is provided, and a second support shaft 24445 is axially movably connected to the end of the first support shaft 24444 away from the fastening gear 24442. A movable meshing gear 24443 is axially movably mounted on the end of the second support shaft 24445 away from the first support shaft 24444, and the drive shaft is correspondingly adapted to the second support shaft 24445. The movable meshing gear 24443 simultaneously meshes with the fastening gear 24442 and the outer ring of the inner meshing gear ring 2443. A meshing compression spring 24446 is sleeved on the drive shaft of the fastening gear 24442. On the outside of the drive shaft of the moving meshing gear 24443, the meshing spring 24446 continuously applies pressure to the drive shaft of the moving meshing gear 24443; the axial angle of the first support shaft 24444 is fixed, and when the third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c move radially, the second support shaft 24445 adaptively swings around the connecting end of the first support shaft 24444, and the elastic force of the meshing spring 24446 always applies axial force to the moving meshing gear 24443, ensuring that it engages with the fastening gear 244. 42. The outer ring of the inner meshing gear ring 2443 maintains stable meshing. The transmission module 244 provides stable power to the pressure rollers. The drive gear 2441 obtains power through the drive spindle and transmits it to the inner meshing gear ring 2443 through the transition gear 2442, forming a power distribution path. The variable transmission component 2444 on the drive shaft of the third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c meshes with the inner meshing gear ring 2443 and the drive gear 2441 to transmit power to each pressure roller, ensuring that the pressure rollers obtain continuous driving force during revolution and rotation.

The moving meshing gear 24443 is axially connected to and limited in the moving limiting groove 3b1. Both the first oil sealing cap 3a and the second oil sealing cap 3b have openings on their sides. There is an oil inlet 3a1, and an oil sealing cap 32 is screwed onto the oil inlet 3a1. The oil sealing cap provides a closed protective structure to improve the reliability of the equipment. The first oil sealing cap 3a and the second oil sealing cap 3b are installed on the outside of the support plate to form a closed space to isolate external impurities. The side oil inlet 3a1 can add lubricating oil in a metered manner. The gear rotation achieves uniform lubrication and reduces transmission friction. The movable limiting groove 3b1 on the inner side of the second oil sealing cap 3b provides guidance for the movable meshing gear 24443 to ensure its stable movement trajectory and reduce component wear and impurity intrusion rate.

The first bearing plate 241a, the second bearing plate 241b, and the relief block 241c are an integral structure. The relief block 241c is located outside the third pressure roller 242a and the fourth pressure roller 242b. The fourth roller 242b and the fifth roller 242c, as well as the fifth roller 242c and the third roller 242a, are all bolted together with a chip removal module 4.

The roller surfaces of the first roller 22, the second roller 23, the third roller 242a, the fourth roller 242b, and the fifth roller 242c are all circumferentially distributed with rolling convex teeth 242c1. The inner wall of the rolling cavity 211 has corresponding clearance grooves 213. The two are staggered to form an interlaced rolling structure. When the rollers rotate, the rolling convex teeth 242c1 and the clearance grooves 213 shear and squeeze the raw material. Through the interlacing action of the teeth and grooves, the wood raw material is further disintegrated and broken, improving the uniformity and fineness of fiber breaking. A clearance block 241c is provided in the gap between the third pressure roller 242a, the fourth pressure roller 242b, and the fifth pressure roller 242c. It adopts an integral molding structure with the first support plate 241a and the second support plate 241b, which not only provides space clearance for the rotation of the pressure rollers, but also serves as the mounting base for the chip removal module 4.

The protruding groove scraping structure 421 at the front end of the inclined bar 42 is adapted to the shape of the rolling protrusion 242c1 and can be embedded between the teeth to remove residual debris. The first and second limiting square rods 45 connect the inclined bars 42 on both sides. A square spring 43 sleeved on the outside of the second limiting square rod 45 continuously applies an elastic thrust to the inclined bar 42 to ensure that it always adaptively conforms to the roller surface when it moves radially with the pressure roller. The top cover 41 is bolted to the top of the first limiting square rod 44 to form a protective structure to prevent debris from entering the module and to achieve simultaneous rolling and chip removal.
