Description

Technical Field

[0001] The present invention belongs to the field of crushers, and particularly relates to a structural assembly of a crusher. Background Art

[0002] With the rapid development of technology, people's requirements for machining (such as crushing operations) are increasing day by day, which makes the quality of the cutting tools themselves particularly important.

[0003] In the prior art, the crushing process of materials indeed faces many challenges. These problems not only affect production efficiency but also directly restrict the improvement of product quality. Specifically:

[0004] 1. Traditional cutting tools are prone to thermal deformation during frequent processing. At the same time, welded cutting tools often suffer from corrosion and oxidation due to welds, seriously affecting the subsequent product processing quality. Moreover, the cutting edges and the tool holder spindle are mostly arranged in parallel, which also makes it extremely easy to have the risk of bag jamming when crushing plastic film bags. These problems not only affect the crushing efficiency and quality but also increase the operation risk.

[0005] 2. Traditional crushing equipment usually relies on a single power source to drive the moving cutter for cutting operations, lacking an effective auxiliary mechanism to enhance the crushing effect. This problem causes some materials to be discharged through the discharge port without being fully cut, resulting in uneven particle size distribution and ultimately affecting the performance and consistency of the final product. Summary of the Invention

[0006] Aiming at the above deficiencies existing in the prior art, the technical problem to be solved by the present invention is to provide a structural assembly of a crusher with a simple overall structure, improved processing performance, crushing efficiency, and crushing quality.

[0007] The technical solution adopted by the present invention to solve its technical problems is to provide a structural assembly of a crusher, including: a housing, which is provided with an installation cavity, a feed port, and a discharge port. The feed port and the discharge port are located on both sides of the radial direction of the installation cavity and are interconnected with it;

[0008] A hob and a fixed cutter. The hob is movably arranged in the installation cavity. A plurality of cutting edges are embedded on the hob. Each cutting edge is made of tungsten steel and undergoes a heat treatment process. Moreover, the inclination direction of each cutting edge forms an angle with the rotation center of the hob to crush the material. The fixed cutter is arranged on the housing and extends movably into the installation cavity. The fixed cutter can move relative to the housing to adjust the gap between the fixed cutter and the cutting edge to prevent the material from being missed cut and falling into the discharge port;

[0009] A driving mechanism is provided on the housing, and the output end of the driving mechanism is connected to the hob, so that when the hob rotates, the cutting edge drives to crush the material.

[0010] After the gap between the fixed knife and the cutting edge is adjusted, the material entering from the feeding port can be crushed by the fixed knife assisting the rotation of the cutting edge and discharged from the discharging port.

[0011] In the above-mentioned structure assembly of a pulverizer, the hob further includes:

[0012] A rotating shaft is provided in the installation cavity. One end of the rotating shaft is connected to the output end of the driving mechanism, and the other end is movably connected to the housing.

[0013] A first fixed knife holder and a second fixed knife holder are provided on the rotating shaft. A first assembly groove is provided on the first fixed knife holder, and a second assembly groove which is arranged in a staggered manner with the first assembly groove is provided on the second fixed knife holder. Both ends of the cutting edge are respectively embedded into the first assembly groove and the second assembly groove.

[0014] In the above-mentioned structure assembly of a pulverizer, the included angle range between the inclination direction of each cutting edge and the axis line of the rotating shaft is 4° - 7°.

[0015] In the above-mentioned structure assembly of a pulverizer, an installation hole is further provided on the housing. A coupling sleeve is arranged in the installation cavity. Bearings are installed at both ends of the rotating shaft, and both the installation hole and the coupling sleeve are in interference fit with the outer rings of the bearings.

[0016] In the above-mentioned structure assembly of a pulverizer, a liquid storage tank and a conveying pipeline are further included. The liquid storage tank is detachably connected to the housing; one end of the conveying pipeline is communicated with the liquid storage tank, and the other end is communicated with the installation hole. A solenoid valve is further installed at one end of the conveying pipeline close to the liquid storage tank.

[0017] In the above-mentioned structure assembly of a pulverizer, an end cover is detachably connected to the housing. The end cover extends into the installation hole movably. A drainage channel is provided in the end cover. A blind hole and a lubrication hole which are communicated with each other are provided on the rotating shaft. One end of the drainage channel is used for connecting the conveying pipeline, and the other end is aligned with the blind hole.

[0018] In the above-mentioned structure assembly of a pulverizer, the driving mechanism includes a driving part and a coupling. The driving part is detachably connected to the housing. The output end of the driving part extends into the installation cavity, and the output end of the driving part is connected to the rotating shaft through the coupling.

[0019] In the above-mentioned structure assembly of a pulverizer, guiding grooves and kidney-shaped holes that are all communicated with the installation cavity are formed on the housing, and the fixed cutter is movably arranged in the guiding grooves; the length direction of the kidney-shaped hole is arranged parallel to the radial direction of the housing for an adjusting member to penetrate through the kidney-shaped hole and be connected to the fixed cutter.

[0020] In the above-mentioned structure assembly of a pulverizer, a fixed cutter mounting plate is further arranged on the housing. The fixed cutter mounting plate is close to the opening end of the guiding groove away from the installation cavity, and a cover plate is detachably connected to the fixed cutter mounting plate.

[0021] In the above-mentioned structure assembly of a pulverizer, feeding pipelines and discharging pipelines are detachably connected to the feeding port and the discharging port respectively.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) In the structure assembly of a pulverizer of the present invention, the cutting edges are made of tungsten steel and are embedded in the fixed cutter holder after heat treatment. This can not only effectively avoid the thermal deformation of the cutter caused by welding, but also avoid the corrosion and oxidation of the material due to the weld seam, reduce the welding process, and greatly enhance its hardness and wear resistance; at the same time, the adjustable design of the fixed cutter enables users to easily adjust the gap between the cutting edge and the fixed cutter according to needs, greatly improving the flexibility of the equipment, as well as the pulverizing efficiency and quality of the material under the cooperation of the two for pulverizing.

[0024] (2) The optimized cutting angle design is used to further improve the pulverizing efficiency, and the inclination angle design is more conducive to bringing the plastic film bag into the pulverizing area to avoid the risk of bag blockage.

[0025] (3) The design of the guiding groove in cooperation with the kidney-shaped hole allows the fixed cutter to move precisely within a certain range, enabling the gap between the cutting edge and the fixed cutter to be finely adjusted according to the characteristics of different materials, simplifying the installation and adjustment process of the fixed cutter, reducing the operation complexity, and at the same time ensuring that the material is thoroughly pulverized, improving the pulverizing accuracy and uniformity.

[0026] (4) By providing a lubricating fluid to the pulverizing area, the wear of the hob and the fixed cutter during the pulverizing operation can be effectively reduced, not only reducing the friction force, but also improving the fluidity and cutting efficiency of the material, making the pulverizing process smoother and more efficient.

[0037] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0038] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0039] Such as Figures 1 to 5As shown in the figure, a structural assembly of a crusher according to the present invention includes: a housing 1, on which an installation cavity 10, a feed port 11 and a discharge port 12 are arranged. The feed port 11 and the discharge port 12 are located on both sides of the installation cavity 10 in the radial direction and are interconnected with each other; a hob 2 and a fixed knife 3. The hob 2 is movably arranged in the installation cavity 10. A number of cutting edges 20 are embedded on the hob 2. Each cutting edge 20 is made of tungsten steel and undergoes a heat treatment process. And the inclination direction of each cutting edge 20 forms an angle with the rotation center of the hob 2 to crush the material; the fixed knife 3 is arranged on the housing 1 and extends into the installation cavity 10 movably. The fixed knife 3 can move relative to the housing 1 to adjust the gap between the fixed knife 3 and the cutting edge 20 to prevent the material from being missed cut and falling into the discharge port 12; a driving mechanism 4 is arranged on the housing 1. The output end of the driving mechanism 4 is connected to the hob 2, so that when the hob 2 rotates, the cutting edge 20 drives to crush the material; after the gap between the fixed knife 3 and the cutting edge 20 is adjusted, the material entering from the feed port 11 can be crushed by the cooperation of the fixed knife 3 and the rotation of the cutting edge 20 and discharged from the discharge port 12.

[0040] Specifically, as Figures 1 to 5 shown, in this embodiment, the material enters the installation cavity 10 through the feed port 11 on the housing 1. The design of the feed port 11 also enables the material to be evenly distributed to the cutting area of the hob 2. When the driving mechanism 4 is started and drives the hob 2 to rotate, the material entering the installation cavity 10 can be crushed by the cutting edge 20. During this process, the worker can pre-install the fixed knife 3 on the housing 1 and adjust the gap between the fixed knife 3 and the cutting edge 20 according to materials of different hardness and sizes, so that the crusher achieves the best crushing effect. It is precisely because of the complementary cutting operations of the fixed knife 3 and the cutting edge 20 that the material can be efficiently and thoroughly crushed in a short time, effectively preventing the material from falling into the discharge pipe without being fully crushed. Compared with the traditional single cutter head design, the double cutter system significantly improves the crushing efficiency and at the same time ensures the consistency and uniformity of the crushing effect. Preferably, both ends of each cutting edge 20 are embedded in the hob 2 to form a stable cutting structure. At the same time, relying on the fact that the cutting edge 20 forms a certain angle with the rotation center of the hob 2, when the hob 2 rotates, the cutting edge 20 can shear, tear and crush the material entering the crushing area at a specific angle; since the cutting edge 20 is made of high-strength tungsten steel material and undergoes a heat treatment process, it has extremely high hardness and wear resistance. As a cemented carbide, the tungsten steel blade is only applied to the position of the cutting edge 20. Even when working for a long time, it can maintain high cutting ability, reduce the replacement and maintenance frequency, and reduce the maintenance cost; in addition, the cutting edge 20 is arranged at an inclined angle, which can not only improve the cutting efficiency, but also increase the chance of the material contacting the tool, helping to bring the plastic film bag into the crushing area and achieving a more thorough crushing effect.

[0041] The hob 2 further includes: a rotating shaft 21 disposed within the installation cavity 10, one end of the rotating shaft 21 being connected to the output end of the driving mechanism 4, and the other end being movably connected to the housing 1; a first fixed cutter holder 3 and a second fixed cutter holder 3 disposed on the rotating shaft 21, a first assembly groove 220 being formed on the first fixed cutter holder 3, and a second assembly groove 230 being formed on the second fixed cutter holder 3 and being arranged in a staggered manner with respect to the first assembly groove 220, and both ends of the cutting edge 20 being respectively inserted into the first assembly groove 220 and the second assembly groove 230.

[0042] Furthermore, as Figures 2 to 4 shown, in addition to the cutting edge 20, the hob 2 in this embodiment further includes a rotating shaft 21 and two fixed cutter holders 3. Each fixed cutter holder 3 is arranged along the radial direction of the rotating shaft 21. Preferably, these fixed cutter holders 3 can be integrally die-cast with the rotating shaft 21, or can be firmly fixed to the rotating shaft 21 by fastening components such as screws or bolts. During the installation process of the cutting edge 20, since the assembly grooves corresponding to the two fixed cutter holders in this embodiment are not in an aligned position (reference can be made to Figure 4 ), by respectively inserting both ends of the cutting edge 20 into the first assembly groove 220 and the second assembly groove 230 arranged in a staggered manner, the stability of the cutting edge 20 during high-speed rotation can be significantly improved, the risk of tool loosening or damage caused by vibration or impact can be reduced, and the safety of the equipment can be improved. The staggered assembly grooves enable the cutting edge 20 to more effectively cover the entire crushing area during rotation, avoiding the occurrence of crushing dead corners; in addition, this embedding method also well avoids the tool thermal deformation caused by welding, and can also avoid the material corrosion and oxidation phenomena caused by the weld seams. While reducing a welding process, the working efficiency is effectively improved.

[0043] Preferably, a certain angle is formed between the installed cutting edge 20 and the rotating shaft 21, and the included angle range between the inclination direction of each cutting edge 20 and the axis line of the rotating shaft 21 is 4° - 7°, and the actual design is 6 degrees. Without increasing additional power input, the oblique cutting force and tearing force generated during the rotation of the cutting edge 20 are used to enhance the crushing effect. Compared with the traditional straight knife design, this structure can more effectively crush materials and reduce the crushing time.

[0044] Further preferably, the number of the cutting edges 20 in this embodiment is not limited to the case of two used in this embodiment. When multiple cutting edges 20 are provided, the inclination directions of any two cutting edges 20 are arranged at an included angle. This design can create a multi-directional and multi-level cutting network in the crushing area (i.e., cutting edges 20 with different inclination angles can be distributed at 360 degrees), ensuring that the material is uniformly and fully stressed in all directions. This not only improves the effectiveness of single cutting, but also greatly increases the possibility of the material being completely crushed, thereby enhancing the overall crushing efficiency.

[0045] The housing 1 is also provided with mounting holes 13. A coupling sleeve 14 is arranged in the mounting cavity 10. Bearings 210 are installed at both ends of the rotating shaft 21. The outer rings of the bearings 210 are in interference fit with the mounting holes 13 and the coupling sleeve 14 in the mounting cavity 10 respectively.

[0046] Furthermore, as Figure 2 shown, in this embodiment, bearings 210 are installed at both ends of the rotating shaft 21. The outer rings of these bearings 210 are tightly connected to the mounting holes 13 on the housing 1 and the coupling sleeve 14 in the mounting cavity 10 respectively by interference fit. This design greatly enhances the stability of the rotating shaft 21 during rotation, reduces noise and the risk of equipment damage caused by vibration, provides working comfort for the crushing environment, and also extends the service life of the equipment.

[0047] This solution further includes a liquid storage tank and a delivery pipe 51. The liquid storage tank is detachably connected to the housing 1; one end of the delivery pipe 51 communicates with the liquid storage tank, and the other end communicates with the mounting hole 13. An electromagnetic valve 52 is also installed at one end of the delivery pipe 51 close to the liquid storage tank.

[0048] Furthermore, as Figure 1 and Figure 2 shown, the liquid storage tank in this embodiment can be installed and fixed on the housing 1 through components such as screws and bolts. This design facilitates the cleaning, maintenance and liquid replenishment of the liquid storage tank. Preferably, the liquid storage tank can store coolant or lubricating fluid. When it is necessary to cool or lubricate the bearings 210 and the hob 2, the control system (not shown in the figure) will automatically open the electromagnetic valve 52 according to preset conditions (such as the data feedback by the temperature sensor), so that the liquid in the liquid storage tank flows through the delivery pipe 51 to the position of the mounting hole 13. Good lubrication and cooling measures can significantly reduce the wear of key components such as the bearings 210, thereby extending the service life of these components and even the entire crusher, and at the same time improving the stability and reliability of the equipment operation.

[0049] A end cover 15 is detachably connected to the housing 1. The end cover 15 extends into the mounting hole 13 movably. A drainage channel 150 is provided in the end cover 15. Blind holes 211 and lubrication holes 212 communicating with each other are provided on the rotating shaft 21. One end of the drainage channel 150 is used to connect the delivery pipe 51, and the other end is arranged in alignment with the blind hole 211.

[0050] Furthermore preferably, as Figure 1 and Figure 2As shown, a connection hole is provided on the housing 1 in this embodiment, and the end cover 15 is detachably connected to the connection hole by components such as screws and bolts. This method not only facilitates maintenance and repair, but also ensures sealing (through a sealing ring, not shown in the figure) and stability. It should be noted that the blind hole 211 in this embodiment is arranged along the axial direction of the rotating shaft 21, and there are multiple lubricating holes 212, and each lubricating hole 212 is arranged along the radial direction of the rotating shaft 21. When the solenoid valve 52 is opened, the liquid in the liquid storage tank is transported through the conveying pipeline 51 to the drainage channel 150 in the end cover 15, so that the liquid flows into the blind hole 211 and is sprayed onto the blade 20, the fixed knife 3 holder and the bearing 210 through the lubricating holes 212. This step ensures that the liquid can directly act on the places that need to be cooled or lubricated, improving the cooling and lubrication effects. In addition, this method not only facilitates the transportation of the liquid, but also makes the daily maintenance and fault troubleshooting of the equipment more convenient and fast, reducing the downtime. Preferably, a plug 151 is also provided on the end cover 15 in this embodiment. The plug 151 movably extends into the drainage channel 150. Therefore, when the liquid does not need to flow, the drainage channel 150 is completely sealed, avoiding potential safety hazards or environmental pollution problems caused by accidental liquid leakage, simplifying the maintenance process, and reducing the time cost of preparation work and cleaning work.

[0051] The driving mechanism 4 includes a driving member 40 and a coupling 41. The driving member 40 is detachably connected to the housing 1. The output end of the driving member 40 extends into the installation cavity 10, and the output end of the driving member 40 is connected to the rotating shaft 21 through the coupling 41.

[0052] Furthermore, as Figure 2 shown, the driving member 40 in this embodiment can also be installed and disassembled by components such as screws and bolts, which will not be elaborated here in detail; when everything is ready, start the driving member 40, and the driving member 40 starts to rotate and transmits the rotational motion to the rotating shaft 21 through the coupling 41. Due to the presence of the coupling 41, even if there are slight installation deviations or small displacements during operation, the smoothness and reliability of power transmission can be ensured. That is, while the coupling 41 transmits power, it also allows a certain degree of misalignment compensation, which is very crucial for reducing the influence of installation errors.

[0053] The housing 1 is provided with a guide groove 16 and a kidney-shaped hole 17 that are both communicated with the installation cavity 10. The fixed knife 3 is movably arranged in the guide groove 16; the length direction of the kidney-shaped hole 17 is arranged parallel to the radial direction of the housing 1 for the adjusting member to pass through the kidney-shaped hole 17 and be connected to the fixed knife 3.

[0054] Furthermore, as Figures 2 to 5As shown, this embodiment relies on the design of the kidney-shaped hole 17 to allow the adjusting member to move freely within a certain range (i.e., the fixed knife 3 approaches or moves away from the installation cavity 10), which means that the operator can flexibly adjust the gap between the fixed knife 3 and the hob 2 according to different material characteristics and crushing requirements, ensuring that all materials can be fully crushed and improving the crushing quality and uniformity. In addition, this adjustment method also simplifies the installation and adjustment process of the fixed knife 3 and reduces the operation complexity. It should be noted that the adjusting member in this embodiment can be replaced by other connecting components such as screws. By passing the adjusting member through the kidney-shaped hole 17 and connecting the fixed knife 3, while realizing the relative movement and position adjustment of the fixed knife 3 with respect to the housing 1, it can also complete the locking function of the fixed knife 3 when the adjusting member abuts against the outer wall of the housing 1, ensuring the stability of the fixed knife 3 during the crushing operation assisted by the hob 2 and avoiding affecting the crushing quality due to other external factors such as mechanical vibration. Specifically, when the operator adjusts the position of the fixed knife 3 through the adjusting member, since the length direction of the kidney-shaped hole 17 is parallel to the radial direction of the housing 1, this ensures that the fixed knife 3 can achieve fine adjustment under the guidance of the guiding groove 16 to reach the optimal working gap. At the same time, the use of this guiding groove 16 also ensures that the fixed knife 3 can be stably maintained at the required position, thus ensuring the efficiency and uniformity of the crushing process.

[0055] Preferably, as Figure 5 shown, this embodiment also forms an avoidance portion 160 and an avoidance groove 161 in the guiding groove 16. Among them, the avoidance portion 160 is preferably an arc surface or two inclined surfaces arranged at an angle. Relying on this design, when the adjusting member penetrates the kidney-shaped hole 17 and is connected to the fixed knife 3, it can perform fine adjustment operations more smoothly; that is, these avoidance portions 160 provide additional space for the adjusting member, reducing the friction and wear between components (i.e., the friction and resistance between the fixed knife 3 and the guiding groove 16 when the fixed knife 3 moves), extending the service life of the fixed knife 3 while ensuring the accuracy and stability of the adjustment. Similarly, through the design of this avoidance groove 161, additional operating space is provided for the fixed knife 3, enabling the fixed knife 3 to move and position more flexibly within the guiding groove 16. This not only improves the flexibility of the adjustment but also effectively avoids the phenomenon of jamming when the fixed knife 3 adjusts its position within the guiding groove 16, ensuring the accuracy of the gap adjustment between the fixed knife 3 and the cutting edge 20 and improving the crushing quality.

[0056] A fixed knife mounting plate 18 is also provided on the housing 1. The fixed knife mounting plate 18 is attached to the opening end of the guiding groove 16 away from the installation accommodation, and a cover plate 180 is detachably connected to the fixed knife mounting plate 18.

[0057] Further preferably, as Figures 2 to 5As shown, as the fixed knife 3 extends into the guide groove 16, at this time, the operator can cover the opening end of the guide groove 16 with the fixed knife mounting plate 18. It should be noted that the fixed knife mounting plate 18 can be detachably connected to the housing 1 through screws, bolts and other connectors, thereby providing a stable basic support point for the fixed knife 3 and ensuring the stability and positioning accuracy after the fixed knife 3 is matched with the adjusting member. With the cover plate 180 fixed in the same installation manner, the phenomenon that the fixed knife 3 fixing plate shakes due to mechanical vibration or other external factors is avoided, effectively improving the stability of the fixed knife 3 fixing plate, ensuring that this structure can guarantee the safety of the operator during the crushing process, with a simple overall structure, making daily cleaning and regular maintenance more convenient and fast, and improving work efficiency.

[0058] Further preferably, as Figure 1 and Figure 2 shown, in this embodiment, guide pipes 19 are detachably connected to both the feeding port 11 and the discharging port 12. According to the characteristics of different materials and production requirements, different specifications or types of guide pipes 19 can be selected for installation, increasing the application range and flexibility of the equipment. Therefore, the guide pipes 19 help to optimize the process of material introduction and discharge, ensure that the materials can be evenly distributed in the crushing area, and can be quickly discharged after crushing, improving work efficiency and quality.

[0059] It should be noted that the driving member 40 in this embodiment can be replaced by other driving devices such as a stepping motor or a servo motor.
