Description

Technical Field

[0001] This invention relates to the field of biomass fuel processing technology, and in particular to a briquetting ring die device. Background Technology

[0002] When utilizing biomass straw, it is necessary to crush and compress it into solid briquettes after drying to facilitate transportation and storage. During the compression into solid briquettes, briquetting ring die equipment is typically used to process the crushed straw material.

[0003] Currently, this type of briquetting ring die equipment utilizes the cooperation between the pressure roller and the outer ring die. The material is mainly drawn from the die inlet into the material cavity and extruded under the frictional force of the pressure roller's revolution. This method is prone to uneven feeding, die blockage, load fluctuations, and unstable equipment operation. Furthermore, long-term use causes wear on the pressure roller surface, increasing the gap between the die and the pressure roller, resulting in poor extrusion molding, inconvenient use and maintenance, and a shorter product lifespan.

It should be understood that such data can be interchanged where appropriate so that embodiments of the invention can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more.

Therefore, "some embodiments" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0059] The following detailed description of a briquetting ring die device provided by the present invention is illustrated through specific embodiments.

[0060] Reference Figures 1 to 3 This invention provides a briquetting ring die device, comprising:

[0061] Ring mold assembly 10;

[0062] The pressure roller assembly 12 includes a pressure roller unit 121 and an adjustment mechanism 122.

[0063] Connector 123;

[0064] The pressure roller unit 121 is sleeved on the adjusting mechanism 122, and the first end of the connecting member 123 is sleeved on the adjusting mechanism 122;

[0065] The transmission assembly 11 has a power input component 111 and a power output component 115. The power input component 111 is fixedly connected to the adjusting mechanism 122, and the power output component 115 is rotatably connected to the second end of the connecting component 123 and is drively connected to the pressure roller unit 121.

[0066] The power input component 111 can drive the pressure roller unit 121 to revolve around the power main shaft 116 of the power input component 111 through the adjusting mechanism 122; at the same time, the power output component 115 can drive the pressure roller unit 121 to rotate around the adjusting mechanism 122 under the action of the power input component 111, so that the pressure roller unit 121 cooperates with the ring die assembly 10 to achieve block forming.

[0067] Figure 1 The diagram shows an isometric view of a briquetting ring die device according to an embodiment of the present invention. This briquetting ring die device can be used to extrude and process biomass materials such as crop straw, transforming them from a loose and fluffy state into compact rod-shaped granular materials, thereby reducing storage and transportation difficulties and costs.

[0068] Combination Figure 1As illustrated, the briquetting ring die equipment may include a functional module for directly processing biomass materials, specifically including a ring die assembly 10, a transmission assembly 11, and a pressure roller assembly 12. It may also include an electric motor 20 for providing driving power to the functional module, a speed reducer 21 for reducing the speed and increasing the torque of the power output from the electric motor 20, and an equipment base 22 for mounting and fixing the functional module. The equipment base 22 may be a structure made of cast iron or welded metal profiles with a metal shell fixed on it. The electric motor 20, the speed reducer 21, and the aforementioned functional module can all be fixed to the equipment base 22. The output shaft of the electric motor 20 and the input shaft of the speed reducer 21 are connected by a coupling, inputting the power of the electric motor 20 into the speed reducer 21. The output shaft of the speed reducer 21 and the power input component 111 of the transmission assembly 11 are connected by a coupling or spline, with the speed reducer 21 driving the transmission assembly 11 to move.

[0069] like Figure 1 As illustrated, the ring die assembly 10 may include an upper pressure plate 101 located above, a support base 102 located below, and a ring die body 103 sandwiched between the upper pressure plate 101 and the support base 102. The upper pressure plate 101, the ring die body 103, and the support base 102 are arranged along... Figure 1In the Z-direction shown, the components are stacked and fixed together from top to bottom, and the support base 102 is also fixed to the equipment base 22 with bolts. The upper pressure plate 101, the ring die body 103, and the support base 102 together form a material cavity 10a with an opening at the top, which is the inlet for feeding biomass materials. A feeding protective cover 104 is also provided at the opening at the top. The feeding protective cover 104 and the upper pressure plate 101 can be fastened with screws. The upper pressure plate 101 is installed and fixed to the ring die body 103. The feeding protective cover 104 has a conical cylindrical structure with two openings through both ends of its axis. The larger opening is closer to the ring die body 103, and the smaller opening is farther away from the ring die body 103, forming the feed inlet, so that the diameter of the feed inlet of the feeding protective cover 104 is small. In another embodiment, the feeding protective cover 104 and the upper pressure plate 101 can also be integrally formed without additional assembly and connection processes. During the material feeding process through the feed inlet, if the material input is large, a significant amount of material may not be compressed into clumps in time, leading to excessive material accumulation within the material cavity 10a and affecting the extrusion process. Therefore, the feed inlet diameter of the feeding guard 104 is small to prevent the input of large amounts of material during feeding. The opening diameter near the inner ring of the ring die body 103 is larger, providing a larger material buffer space and reducing the adverse effects of material accumulation on the extrusion process. The ring die body 103 has radially oriented through-holes around its perimeter, which serve as the outlets for the biomass material. After being compressed within the material cavity 10a, the biomass material is discharged through these through-holes to form dense granular material. A portion of the transmission assembly 11 is located within the material cavity 10a. The power input component of the transmission assembly 11 extends downwards from the material cavity 10a to the location of the reducer 21 on the equipment base 22, connecting to the output shaft of the reducer 21. The reducer 21 drives the transmission assembly 11 through the power input component.

[0070] Combination Figure 2 and Figure 3 The disassembly diagram shows that the ring die device in this embodiment of the invention also includes a connector 123. Furthermore, the pressure roller assembly 12 installed in the material cavity 10a may include a pressure roller unit 121 and an adjusting mechanism 122. The connector 123 is a strip-shaped connecting rod or connecting plate with through holes at both ends. The first end of the connector 123 is sleeved on the adjusting mechanism 122, and the power output component 115 is rotatably connected to the second end of the connector 123. Simultaneously, the connector 123 itself can also slide relative to the ring die assembly 10.

[0071] like Figure 2 and Figure 3As illustrated, when the power from the motor 20 drives the reducer 21 to rotate, the reducer 21 then drives the connected power input component 111 to move. Since the adjusting mechanism 122 is fixed on the power input component 111 of the transmission assembly 11, and the pressure roller unit 121 is sleeved on the adjusting mechanism 122, the adjusting mechanism 122 can move together with the power input component 111. At this time, the pressure roller unit 121, driven by the adjusting mechanism 122, can revolve around the power main shaft 116 of the power input component 111. Furthermore, since the pressure roller unit 121 is also connected to the power output component 115 of the transmission assembly 11, the power output component 115 can drive the pressure roller unit 121 to rotate around the adjusting mechanism 122 under the action of the power input component 111.

[0072] It should be noted that the transmission assembly 11 in this embodiment of the invention is used to transmit power from the front motor 20 and the reducer 21 to the end actuator (i.e., the pressure roller assembly 12). The transmission assembly 11 can ensure that the pressure roller assembly 12 has the characteristics of revolution and rotation. The specific structural form of the transmission assembly 11 can be a planetary gear transmission mechanism, a bevel gear transmission mechanism, a transmission mechanism composed of multiple spur gears or helical gears, etc. This embodiment of the invention does not limit the specific structural form of the transmission assembly 11.

[0073] As can be seen, in the briquetting ring die equipment of this embodiment of the invention, the pressure roller unit 121, while revolving around the power main shaft 116 of the power input component 111, also has the characteristic of rotation. Therefore, when biomass material is compressed in the material chamber 10a, in addition to providing extrusion force through its revolution, the pressure roller unit 121's rotation can also supplement the extrusion force, preventing material blockage and stagnation caused by insufficient extrusion force. This achieves forced feeding and extrusion of biomass material, helping to improve the molding and processing efficiency of biomass material.

[0074] Furthermore, in this embodiment of the invention, since an adjusting mechanism 122 is used in the pressure roller assembly 12, when the angle of the adjusting mechanism 122 is adjusted to make it rotate, the pressure roller unit 121 sleeved on its outside can be driven to rotate. As a result, the working distance between the outer periphery of the pressure roller unit 121 and the inner wall of the material cavity 10a changes and can be adjusted. For example, with the long-term use of the briquetting ring die equipment, after the outer surface of the pressure roller unit 121 wears, the working distance between the outer periphery and the inner wall of the material cavity 10a increases, which makes the extrusion molding effect and efficiency of biomass materials worse. The angle of the adjusting mechanism 122 can be adjusted to reduce the working distance.

[0075] It is easy to understand that adjusting the working distance between the outer periphery of the pressure roller unit 121 and the inner wall of the material cavity 10a can easily cause the original rotational power transmission path to be broken. Therefore, in this embodiment of the invention, in order to ensure that the rotational function of the briquetting ring die device is intact before and after the working distance is adjusted, a connector 123 that can slide relative to the ring die assembly 10 is provided. The sliding of the connector 123 provides movement space for the translation of the pressure roller unit 121, avoiding jamming of the pressure roller unit 121. At the same time, the power input component (pressure roller gear 1211) for receiving driving power in the pressure roller unit 121 and the power output component 115 of the transmission assembly 11 are both mounted on the connector 123, and the transmission connection between the two is constrained by the connector 123, so the transmission cannot be broken. During the sliding of the connector 123 relative to the ring die assembly 10, the rotational power transmission path from the power output component of the transmission assembly 11 to the pressure roller unit 121 can always be kept open.

[0076] As can be seen from the above description of the embodiments, the briquetting ring die equipment of this embodiment of the invention, in addition to improving the smoothness and processing efficiency of biomass material forming by utilizing the revolution and rotation of the pressure roller unit 121, and making the equipment run more smoothly, can also adjust the working spacing in a timely manner according to the wear degree of the pressure roller unit 121, thereby reducing the maintenance operation of disassembling and replacing parts, improving the convenience of equipment maintenance, and helping to extend the service life of the equipment.

[0077] Optionally, refer to Figure 1 or Figure 2 The transmission component 11 is a planetary gear transmission mechanism.

[0078] like Figure 1 or Figure 2 As illustrated, in one embodiment, the transmission component 11 of this invention can be a planetary gear transmission mechanism. The planetary gear transmission mechanism has a compact structure and does not require excessive space. Using it as the transmission component 11 can free up more space within the material chamber 10a for accommodating biomass materials.

[0079] Furthermore, it should be noted that planetary gear transmission mechanisms can be structured in two ways: the main shaft rotates to drive the sun gear, which in turn drives the planet gears; or the sun gear remains stationary while the main shaft rotates relative to it, driving the planet carrier to rotate, which in turn drives the planet gears to rotate around the sun gear. In practical applications, technicians can choose either planetary gear transmission mechanism based on the specific installation and layout requirements of the structure.

[0080] Optionally, refer to Figures 2 to 9 The power input component 111 further includes:

[0081] Sun gear 112, which is fixedly connected to the ring mold assembly 10;

[0082] The lower support bracket 114 of the pressure roller is fixedly connected to the main power shaft 116. The pressure roller assembly 12 is fixedly connected to the lower support bracket 114 of the pressure roller. The lower support bracket 114 of the pressure roller is provided with an arc-shaped track 1141 around the circumference of the sun gear 112. The arc-shaped track is located on the circumference of the concentric circle of the sun gear 112. The connecting member 123 can slide along the arc-shaped track 1141.

[0083] The power output component 115 is a planetary gear, which meshes with the sun gear 112.

[0084] In addition, in order to improve the motion stability of the pressure roller assembly 12, the power input component 111 in this embodiment preferably includes an upper pressure roller bracket 113, which is fixedly connected to the power main shaft 116. The lower pressure roller bracket 114 and the upper pressure roller bracket 113 are spaced apart along the axial direction of the power main shaft 116 to form a clamping space, and the pressure roller assembly 12 is located in the clamping space.

[0085] like Figures 2 to 5 The diagram illustrates the structure of the transmission component 11 of this invention, which uses a planetary gear transmission mechanism. Referring to the diagram, the planetary gear transmission mechanism includes a power spindle 116, a sun gear 112, an upper support 113 for the pressure roller, a lower support 114 for the pressure roller, and planetary gears 115. The power spindle 116 can be a stepped shaft structure with multiple shoulders at different positions for mounting and fixing other components. The power spindle 116 is installed along the Z direction as shown in the diagram. The lower end of the power spindle 116 passes through a pre-drilled hole at the bottom of the support base 102 and extends from the bottom of the support base 102. A pair of bearings can be installed back-to-back between the power spindle 116 and the through hole at the bottom of the support base 102, making the rotation of the power spindle 116 relative to the support base 102 smoother and easier. The lower end of the power spindle 116 can be connected to the output shaft of the reducer 21 via a coupling or spline. Thus, the power spindle 116 serves as an input component, receiving power output from the reducer 21. The reducer 21 drives the power spindle 116, the upper support of the pressure roller 113, and the lower support of the pressure roller 114 to rotate relative to the ring die assembly 10.

[0086] The sun gear 112 is fastened to the bottom of the support base 102 via a gear fixing seat and screws, and is located within the material cavity 10a. Simultaneously, the power spindle 116 passes through the through hole in the center of the sun gear 112. When the power spindle 116 rotates, the sun gear 112 remains stationary along with the support base 102. Therefore, the planetary gear transmission mechanism of this embodiment is a transmission mechanism in which the sun gear 112 is fixed.

[0087] like Figure 2 and Figure 3 As shown, the upper support 113 of the pressure roller can be a plate-shaped component with a mounting hole at its center. After the upper end of the power spindle 116 extends out of the mounting hole, the upper support 113 of the pressure roller abuts against the shoulder of the power spindle 116. A locking nut 30 is provided above the upper support 113 of the pressure roller, and the locking nut 30 is tightened and fixed to the upper end of the power spindle 116, thus fixing the upper support 113 of the pressure roller onto the power spindle 116. Furthermore, the upper support 113 of the pressure roller extends radially in a direction away from the central mounting hole to form three connecting arms. The three connecting arms are evenly distributed at 120°, and each connecting arm can be used to install and fix a set of pressure roller assembly 12.

[0088] Combination Figure 2 and Figure 3 As can be understood from the illustration, the number of pressure roller assemblies 12 is the same as the number of connecting arms on the pressure roller support 113. In addition, in some embodiments, there may be two or more connecting arms. As the number of connecting arms increases, the pressure roller assembly 12 is more conducive to improving the processing and molding efficiency of biomass materials.

[0089] like Figure 2 and Figure 3 As shown, the lower roller support 114 is a disc-shaped part with a cylindrical structure having a through hole in the center. The power spindle 116 passes through this through hole and extends downwards. The lower roller support 114 is supported on another shoulder of the power spindle 116. Another locking nut 30 is located above the lower roller support 114 and is tightened and fixed to the middle of the power spindle 116, thus fixing the lower roller support 114 to the power spindle 116. The cylindrical structure of the lower roller support 114 passes through the opening in the center of the sun gear 112, and a rotatable gap is provided between the outer wall of the cylindrical structure and the opening in the center of the sun gear 112. Simultaneously, the lower roller support 114 also extends radially away from the central through hole to form a support portion for supporting and mounting the pressure roller assembly 12. The number of support portions can be the same as the number of connecting arms of the upper roller support 113; of course, all support portions can be connected together to form a flat plate structure.

[0090] The upper support 113 and the lower support 114 of the pressure roller are fixedly connected to the main power shaft 116 to form a planetary carrier in the planetary gear transmission mechanism. In this planetary carrier, the upper support 113 and the lower support 114 of the pressure roller are distributed vertically at intervals along the axial direction of the main power shaft 116, forming a space for installing the pressure roller assembly 12. The upper end of the pressure roller assembly 12 is fixed to the upper support 113 of the pressure roller, and the lower end is fixed to the lower support 114 of the pressure roller. The pressure roller assembly 12 is sandwiched between the upper support 113 of the pressure roller and the lower support 114 of the pressure roller.

[0091] Combination Figures 2 to 5 As illustrated, the lower support 114 of the pressure roller is provided with an arc-shaped track 1141 around the circumference of the sun gear 112. The arc-shaped track 1141 can be an arc-shaped groove recessed from the surface of the lower support 114 of the pressure roller, or it can be a guide strip protruding from the surface of the lower support 114 of the pressure roller. The arc-shaped track 1141 is located on the circumference of the concentric circle of the sun gear 112, that is, the center of the arc-shaped track 1141 coincides with the center of the sun gear 112.

[0092] The planetary gear 115, serving as the power output component of the planetary gear transmission mechanism, is mounted at the second end of the connecting member 123 and can be rotatably connected to the connecting member 123 via a rotating shaft. For example, the rotating shaft and the planetary gear 115 are interference-fitted via a flat key. The rotating shaft passes through a through hole at the second end of the connecting member 123, and a bearing can be installed between the rotating shaft and the through hole. Furthermore, the lower end of the rotating shaft is embedded in the corresponding arc-shaped groove of the arc-shaped track 1141. Thus, the planetary gear 115 and the rotating shaft can rotate relative to the connecting member 123, and they rotate synchronously. At the same time, the connecting member 123 is also constrained by the fit between the rotating shaft and the arc-shaped groove, allowing it to translate along the arc-shaped trajectory.

[0093] In another configuration, the second end of the connector 123, facing away from the arc-shaped groove, can protrude to form a connecting shaft. The connecting shaft is fixed integrally with the connector 123. The planetary gear 115 can be sleeved on the outside of the connecting shaft. A bearing can be installed between the planetary gear 115 and the connecting shaft. Furthermore, the second end of the connector 123, near the arc-shaped groove, can protrude towards the arc-shaped groove to form a guide post. The guide post is embedded in the corresponding arc-shaped groove of the arc-shaped track 1141. Thus, the planetary gear 115 can rotate relative to the connecting shaft. At the same time, the connector 123 is also constrained by the cooperation relationship between the guide post and the arc-shaped groove, and can translate along the arc-shaped trajectory.

[0094] In addition, it should be noted that in some embodiments, a linkage mechanism consisting of multiple links can be used as a planetary carrier to maintain the meshing of the planetary gear 115 and the sun gear 112, as well as the transmission connection between the planetary gear 115 and the pressure roller unit 121.

[0095] Therefore, in the planetary gear transmission mechanism of this embodiment, when the planetary carrier composed of the upper support 113 and the lower support 114 of the pressure roller rotates with the main power shaft 116, it can drive the pressure roller assembly 12 to revolve around the main power shaft 116. Moreover, as shown in the figure, it can be understood that when the angle of the adjusting mechanism 122 is adjusted, causing the connecting member 123 to slide relative to the lower support 114 of the pressure roller, the planetary gear 115 also slides accordingly. Since the planetary gear 115 is limited by the arc track 1141, the planetary gear 115 always maintains a meshing relationship with the sun gear 112 during the sliding process. Therefore, when adjusting the working distance between the outer periphery of the pressure roller unit 121 and the inner wall of the material cavity 10a, the rotational power of the pressure roller unit 121 is not cut off. Figures 6 to 9 The diagram also shows a comparison of the adjustment mechanism 122 at position A, indicated by the dashed box, before and after adjustment. Figure 6 This diagram illustrates the device with a large working distance before the adjustment mechanism 122 at position A is adjusted. When the device has a large working distance, the corresponding position is characterized by the narrowest distance L1 between the outer periphery of the pressure roller gear 1211 and the inner wall of the material cavity 10a. Figure 7 It also shows Figure 6 The diagram shows the position after the gear is removed. At this point, the narrowest distance between the outer periphery of the connector 123 and the inner wall of the material cavity 10a is L1'. Along... Figure 6 In the direction indicated by the middle arrow M, rotate the eccentric sleeve 1222 of the adjusting mechanism 122 at position A until it rotates to... Figure 8 At the indicated position, the pressure roller gear 1211, pressure roller hub 1213, and pressure roller gear ring 1214 are all closer to the inner wall of the material cavity 10a. This device has a smaller working distance. Corresponding to this position, the narrowest distance between the outer circumference of the pressure roller gear 1211 and the inner wall of the material cavity 10a is L2, where L2 is less than L1. Figure 9 It also shows Figure 8 The diagram shows the position after the gear is removed. At this point, the narrowest distance between the outer periphery of the connector 123 and the inner wall of the material cavity 10a is L2', which is less than L1'. It should also be noted that in this embodiment, the adjusting mechanisms 122 in different positions can be adjusted independently to change the working distance at their respective positions.

[0096] Optionally, refer to Figure 4 and Figure 5 The adjusting mechanism 122 is an eccentric mechanism, comprising:

[0097] The pressure roller shaft 1221 is located in the clamping space and is fixedly connected to the upper pressure roller bracket 113 and the lower pressure roller bracket 114.

[0098] An eccentric sleeve 1222 is provided with an eccentric hole 12221. The eccentric sleeve 1222 is sleeved on the outside of the pressure roller shaft 1221 and is clearance-fitted with the pressure roller shaft 1221. The eccentric sleeve 1222 passes through the through hole at the first end of the connector 123 and is clearance-fitted with the connector 123.

[0099] It is understood that in some other embodiments, when the briquetting ring die equipment does not have an upper support 113 for the pressure roller, the pressure roller shaft 1221 may be fixedly connected only to the lower support 114 for the pressure roller.

[0100] like Figure 4 and Figure 5As illustrated, the adjusting mechanism 122 of this embodiment can be an eccentric mechanism, including a pressure roller shaft 1221 and an eccentric sleeve 1222. The eccentric sleeve 1222 is provided with an eccentric hole 12221, the center of which is offset from the center of the outer circle of the eccentric sleeve 1222. The pressure roller shaft 1221 passes through the eccentric hole 12221, and a rotatable gap is reserved between the outer wall of the pressure roller shaft 1221 and the inner wall of the eccentric hole 12221. Both ends of the pressure roller shaft 1221 protrude from the eccentric hole 12221 of the eccentric sleeve 1222. The upper end of the pressure roller shaft 1221 can pass through the mounting hole of the upper support 113 of the pressure roller and be interference-fitted therewith or fastened by another locking nut 30. The lower end can pass through the mounting hole of the lower support 114 of the pressure roller and be interference-fitted therewith. In another installation structure, the mounting holes of the upper support 113 and the lower support 114 of the pressure roller can also be designed as blind holes. The upper and lower ends of the pressure roller shaft 1221 are respectively inserted into the corresponding blind holes and interference-fitted with them, thereby clamping and fixing the pressure roller shaft 1221 between the upper support 113 and the lower support 114 of the pressure roller.

[0101] Therefore, since the pressure roller shaft 1221 is fixed together with the lower pressure roller support 114, the pressure roller shaft 1221 can transmit the power of the lower pressure roller support 114 rotating with the power main shaft 116 to the pressure roller unit 121, driving the pressure roller unit 121 to revolve. Furthermore, the clearance fit between the eccentric sleeve 1222 and the pressure roller shaft 1221, and the clearance fit between the eccentric sleeve 1222 and the connecting piece 123, ensures that when the eccentric sleeve 1222 is rotated for adjustment, the connecting piece 123 is prevented from rotating at the same angle.

[0102] In other implementations, other eccentric mechanisms, such as eccentric shafts, can also be used as the adjustment mechanism. Their specific structures are existing technologies and will not be described in detail here.

[0103] Optionally, refer to Figures 4 to 5 The pressure roller unit 121 includes:

[0104] The pressure roller gear 1211 and the pressure roller hub 1213 are fixedly connected and rotatably sleeved on the outside of the eccentric sleeve 1222. The pressure roller gear 1211 meshes with the planetary gear 115.

[0105] The pressure roller unit 121 preferably includes a pressure roller tooth ring 1214, which is integrally formed with the pressure roller hub 1213 or fixed on the outer peripheral surface of the pressure roller hub 1213.

[0106] The pressure roller unit 121 preferably includes a pressure roller end cover 1212, which is fixedly connected between the pressure roller gear 1211 and the pressure roller hub 1213.

[0107] like Figures 4 to 5 As illustrated, the pressure roller unit 121 of this embodiment may include a pressure roller gear 1211, a pressure roller end cover 1212, a pressure roller hub 1213, and a pressure roller gear ring 1214. The pressure roller gear 1211 is sleeved on the outside of the eccentric sleeve 1222 with a clearance fit, and also meshes with the planetary gear 115. It can be understood that since the planetary gear 115 is assembled and connected to one end of the connecting member 123, and the eccentric sleeve 1222 is assembled and connected to the other end of the connecting member 123, when the eccentric sleeve 1222 rotates to adjust the working distance between the outer periphery of the pressure roller unit 121 and the inner wall of the material cavity 10a, the connecting member 123 sleeved on the outside of the eccentric sleeve 1222 and the pressure roller gear 1211 move together to ensure that the pressure roller gear 1211 is always meshed with the planetary gear 115.

[0108] The pressure roller end cover 1212 can be a circular disc cover-like part located below the pressure roller gear 1211. The pressure roller end cover 1212 has a through hole in the center. The pressure roller end cover 1212 is sleeved on the outside of the eccentric sleeve 1222 and a rotation gap is reserved between it and the outer wall of the eccentric sleeve 1222. The lower end face of the pressure roller end cover 1212 can be fixedly connected to the pressure roller gear 1211 by screws. When the pressure roller gear 1211 rotates, it drives the pressure roller end cover 1212 to rotate synchronously.

[0109] The pressure roller hub 1213 is a circular hub with a central through hole. The pressure roller hub 1213 is fitted onto the outside of the eccentric sleeve 1222, and a pair of back-to-back rolling bearings can be installed between them to allow free rotation of the pressure roller hub 1213 relative to the eccentric sleeve 1222. Of the pair of rolling bearings between the pressure roller hub 1213 and the eccentric sleeve 1222, the inner ring of the lower rolling bearing is interference-fitted with the eccentric sleeve 1222 and can abut against the shoulder limiting structure of the eccentric sleeve 1222, while its outer ring is interference-fitted with the pressure roller hub 1213. The inner ring of the upper rolling bearing is interference-fitted with the eccentric sleeve 1222, and its outer ring is interference-fitted with the pressure roller hub 1213. Furthermore, as shown in the diagram, the inner and outer rings of the upper rolling bearing have a height difference along the axial direction of the eccentric sleeve 1222. This allows for a clearance between the upper surface of the pressure roller hub 1213 and the lower surface of the pressure roller upper support 112, preventing friction between the pressure roller hub 1213 and the pressure roller upper support 112 during rotation. The lower surface of the pressure roller hub 1213 abuts against the upper surface of the pressure roller end cover 1212, and this connection can be secured together with screws, ensuring that the pressure roller hub 1213 and the pressure roller end cover 1212 rotate synchronously.

[0110] Thus, the pressure roller hub 1213 is fixed between the pressure roller upper bracket 112 and the pressure roller end cover 1212. When the pressure roller end cover 1212 rotates, it can drive the pressure roller hub 1213 to rotate. At the same time, the pressure roller end cover 1212 can shield the lower end of the pressure roller hub 1213 to prevent foreign objects from entering between the pressure roller hub 1213 and the eccentric sleeve 1222, thus preventing obstruction of rotation.

[0111] In addition, a pressure roller toothed ring 1214 is fixed on the outer circumferential surface of the pressure roller hub 1213. The pressure roller toothed ring 1214 can be a ring-shaped toothed ring or a fan-shaped toothed ring with roller pressing teeth, made of wear-resistant ceramic or alloy material, to improve the wear resistance of the pressure roller unit 121. Taking the ring-shaped toothed ring as an example, the ring-shaped toothed ring can be sleeved on the outside of the pressure roller hub 1213, and the two are connected by a flat key, so that the rotation of the pressure roller hub 1213 can drive the pressure roller toothed ring 1214 to rotate synchronously. Furthermore, in order to prevent the pressure roller toothed ring 1214 from being lifted up and loosened by the material when rotating, a fixing plate is installed on the pressure roller hub 1213. The fixing plate is tightened and fixed on the pressure roller hub 1213 with screws. The fixing plate blocks part of the pressure roller toothed ring 1214 to form a limiting and resisting effect, preventing the pressure roller toothed ring 1214 from moving along the axial direction. The fixing method of the pressure roller tooth ring 1214 makes it removable and replaceable, which improves the convenience of maintenance.

[0112] Optionally, refer to Figure 5 The pressure roller tooth ring 1214 is provided with at least two layers of spaced-apart pressure roller teeth.

[0113] like Figure 5 As shown, along the axial direction Z of the power spindle 116, the roller teeth on the pressure roller tooth ring 1214 can be two or more layers, thereby improving the lifespan and processing efficiency of the pressure roller tooth ring 1214.

[0114] Optionally, refer to Figure 4 , Figure 5 and Figure 10 The pressure roller unit 121 further includes:

[0115] The first sealing element 1215 is sleeved on the outside of the eccentric sleeve 1222 and fixedly connected to the eccentric sleeve 1222, and the first sealing element 1215 is disposed on the upper end face of the pressure roller hub 1213.

[0116] like Figure 4 , Figure 5 and Figure 10As shown, in order to prevent foreign objects such as debris and dust from entering between the eccentric sleeve 1222 and the pressure roller hub 1213 during the processing of biomass materials, a first sealing element 1215 is provided on the upper end face of the pressure roller hub 1213. The first sealing element 1215 can be a sealing plate with a tortuous labyrinth sealing structure. The first sealing element 1215 has a through hole in the middle, which can be sleeved on the outside of the eccentric sleeve 1222, and the two can be fixed together by a limiting block 1216. When the first sealing element 1215 is rotated, the eccentric sleeve 1222 can be pushed to rotate. At this time, the first sealing element 1215 and the eccentric sleeve 1222 rotate together.

[0117] Optionally, refer to Figure 2 , Figure 10 and Figure 11 The pressure roller unit 121 also includes fastening screws;

[0118] The first sealing element 1215 is provided with a positioning hole 12151;

[0119] The upper support 113 of the pressure roller is provided with a plurality of adjustment holes 1131 or a continuous arc-shaped adjustment groove distributed at intervals along an arc-shaped trajectory, wherein the arc shape of the arc-shaped trajectory or the arc-shaped adjustment groove is a segment of the arc length of the concentric circle of the eccentric sleeve 1222.

[0120] When the first seal 1215 rotates, the fastening screw passes through any of the adjustment holes 1131 or the adjustment groove and extends into the positioning hole 12151, and the upper bracket 113 of the pressure roller is fixedly connected to the first seal 1215 by the fastening screw.

[0121] like Figure 2 , Figure 10 and Figure 11As shown in the embodiment of the invention, the pressure roller unit 121 further includes a fastening screw (not shown in the figure), the first sealing member 1215 is provided with at least one positioning hole 12151, and the upper support 113 of the pressure roller is provided with a plurality of adjusting holes 1131 or a continuous arc-shaped adjusting groove distributed at intervals along an arc trajectory, wherein the arc is a segment of the arc length of the concentric circle of the eccentric hole 12221. When it is necessary to adjust the working distance, loosen the fastening screw, disconnect the upper support 113 of the pressure roller from the first sealing member 1215, rotate the first sealing member 1215, so that different positions of the adjusting holes 1131 or different parts of the arc-shaped adjusting groove are aligned with the positioning hole 12151. After the working distance is adjusted appropriately, the fastening screw is inserted into the positioning hole 12151 after passing through the adjusting hole 1131 or the arc-shaped adjusting groove, and the fastening screw is tightened to fix the eccentric sleeve 1222 in place, so that the working distance remains stable until the pressure roller tooth ring 1214 wears and the distance becomes larger, and the next adjustment is required. This pressure roller unit 121 provides a simple and easy-to-operate structure for adjusting the working distance of the biomass material, and can achieve segmented or continuous stepless adjustment.

[0122] Optionally, refer to Figure 5 or Figure 11 The briquetting ring die equipment also includes a protective cover 13 that is integrally formed with or detachably connected to the lower support of the pressure roller 114;

[0123] The protective cover 13 is disposed around the lower support bracket 114 of the pressure roller, and the protective cover 13 encloses and shields at least one of the sun gear 112, the planet gear 115 and the pressure roller gear 1211.

[0124] like Figure 5 or Figure 11 As shown in the embodiment of the present invention, the briquetting ring die equipment also includes a protective cover 13. The protective cover 13 is disposed around the lower support bracket 114 of the pressure roller and surrounds the sun gear 112, planet gear 115 and pressure roller gear 1211 in the material cavity 10a to prevent the material from being rolled into the gear meshing transmission part during the material processing process and to avoid causing the gear transmission to be blocked.

[0125] Optionally, refer to Figure 12 The briquetting ring die equipment also includes a sliding sealing assembly 14;

[0126] The sliding sealing assembly 14 is disposed between the protective cover 13 and the pressure roller hub 1213, and can slide relative to the protective cover 13 or the pressure roller hub 1213.

[0127] like Figure 12As shown in the embodiment of the present invention, since the pressure roller hub 1213 in the pressure roller unit 121 of the briquetting ring die equipment can be translated with the eccentric sleeve 1222, a sliding sealing component 14 is also provided between the protective cover 13 and the pressure roller hub 1213. When the working distance of the briquetting ring die equipment is adjusted, the sliding sealing component 14 can slide relative to the protective cover 13 or the pressure roller hub 1213, so that the briquetting ring die equipment forms a dynamic seal, which not only ensures the distance adjustment function, but also takes into account the sealing performance.

[0128] Optionally, refer to Figure 12 The sliding sealing assembly 14 includes a second seal 141;

[0129] The first surface of the second seal 141 is provided with a labyrinth sealing groove;

[0130] The second seal 141 is fixed to the pressure roller hub 1213 through the labyrinth sealing groove.

[0131] like Figure 12 As shown, in one embodiment, the sliding sealing assembly 14 includes a second sealing element 141. The side of the second sealing element 141 facing the pressure roller hub 1213 is a first side, and the side facing away from the pressure roller hub 1213 is a second side. The first side has a tortuous labyrinth sealing groove. The labyrinth sealing groove abuts against and fixes the second sealing element 141 to the pressure roller hub 1213, thereby sealing the assembly gap between the two. In addition, a sealing ring 142 can be provided on the second side of the second sealing element 141. The sealing ring 142 can be made of an elastic material. When adjusting the working gap, the pressure roller hub 1213 translates, causing the second sealing element 141 to compress the sealing ring 142 and deform. At this time, the sealing ring 142 slides against the protective cover 13, thus ensuring both sealing and the realization of the gap adjustment function.

[0132] Optionally, refer to Figure 12 The sliding sealing assembly 14 also includes a pressure plate 143;

[0133] The pressure plate 143 is fixed to the second side of the second sealing member 141. One side of the pressure plate 143 has a groove. The sealing ring 142 is embedded in the groove and slides against the protective cover 13. Preferably, the surface roughness of the pressure plate 143 with the groove is less than the surface roughness of the second sealing member 141.

[0134] like Figure 12As shown, in one embodiment, the sliding sealing assembly 14 may further include a pressure plate 143, which is fixed to the second surface of the second sealing member 141, and has a groove on the side facing away from the second sealing member 141, in which the sealing ring 142 is embedded. It should be noted that the width of the groove is slightly greater than the thickness of the sealing ring 142, so that the sealing ring 142 has room for sliding deformation. In addition, the surface roughness of the pressure plate 143 with the groove is less than the surface roughness of the second sealing member 141, which can reduce the resistance when the pressure plate 143 slides relative to the protective cover 13, resulting in less resistance when adjusting the working distance.

[0135] Optionally, refer to Figure 11 The protective cover 13 includes a side shell 131 and a top cover 132 that are integrated together. The side shell 131 is detachably connected to the lower support bracket 114 of the pressure roller.

[0136] like Figure 11 As shown, in one embodiment, the protective cover 13 of the present invention can be a shell structure including a side shell 131 and a top cover 132. The side shell 131 and the top cover 132 are an integral unit, and the side shell 131 and the lower support bracket 114 of the pressure roller can be detachably connected by screws. The side shell 131 surrounds and blocks the pressure roller gear 1211 and the planetary gear 115 from all sides, and the top cover 132 blocks the pressure roller gear 1211 and the planetary gear 115 from above.

[0137] Optionally, refer to Figure 12 The protective cover 13 is integrally formed with the lower support of the pressure roller 114. The protective cover 13 extends from the edge of the lower support of the pressure roller 114 toward the pressure roller hub 1213 and surrounds the pressure roller gear 1211.

[0138] like Figure 12 As shown, in one embodiment, the protective cover 13 of this invention can also be integrally formed with the lower support of the pressure roller 114. That is, when manufacturing the lower support of the pressure roller 114, the side shell 131 is formed together. The side shell 131 extends from the edge of the lower support of the pressure roller 114 toward the pressure roller hub 1213, surrounding the pressure roller gear 1211. In addition, when the gap between the edge of the side shell 131 and the opening of the pressure roller hub 1213 is too large, a top cover 132 can also be formed together. The top cover 132 serves as a shield and also provides a larger installation contact area for the sliding sealing assembly 14, ensuring sufficient sliding stroke. This integrated structure that combines the protective cover 13 and the lower support of the pressure roller 114 has higher mechanical strength, more stable and reliable operation, and a longer service life.

[0139] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.

[0140] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
