Description

Technical Field

[0001] This utility model relates to the field of biochar extrusion molding technology, and more specifically, to a biochar extrusion molding machine. Background Technology

[0002] Biochar extrusion molding machines require a drive assembly to rotate the extrusion rod for extrusion molding. In actual production applications, due to the uneven density, fluctuating moisture content, and significant differences in hardness of biomass raw materials, sudden changes in resistance often occur during extrusion, leading to a sharp increase in equipment load. To prevent serious mechanical failures such as motor overload damage or extrusion rod breakage, existing technologies generally require the installation of an overload protection device between the drive assembly and the extrusion rod. However, the overload protection devices used in most biochar extrusion molding machines on the market are too simple in structure. Once installed, the overload protection threshold is fixed and cannot be adjusted according to the actual usage needs such as the characteristics of different types of biomass raw materials, different production batch requirements, different product specifications, and different production environment conditions. As a result, when the protection threshold is too high, it cannot effectively protect equipment components, and when the protection threshold is too low, the protection mechanism is frequently triggered, leading to a series of adverse effects such as low production efficiency and excessive equipment downtime.

[0003] Secondly, although some improved biochar extrusion molding machines have achieved preliminary adjustment of the overload protection threshold through the cooperation of some components, these adjustment mechanisms generally have simple structures and insufficient stability. They are easily affected by various external forces such as continuous vibrations generated by long-term equipment operation, impacts from frequent start-stops, and accidental collisions during maintenance by operators. This can cause the adjusted components to loosen or shift, resulting in irregular changes or drifts in the adjusted protection threshold. This causes deviations between the actual operating protection threshold and the set value, and in severe cases, it can even lead to a complete failure of the protection function, ultimately resulting in a series of adverse production and economic impacts such as raw material waste, product quality fluctuations, frequent equipment failures, increased maintenance costs, decreased production efficiency, and increased labor intensity for operators.

[0007] The present invention is further configured such that a sensitive groove is provided on the inner side of the migration block, a sensitive spring is movably provided in the sensitive groove, one end of the sensitive spring is connected to the inner wall of the sensitive groove, and a configuration block is connected to the other end of the sensitive spring, the configuration block being inserted into the configuration groove.

[0008] The present invention is further configured such that a matching spring is movably sleeved on the outer side of the matching rod, one end of the matching spring is connected to the retaining sleeve, and the other end of the matching spring is in contact with the matching plate.

[0009] The present invention is further configured such that a following groove is provided on one side of the following sleeve, a following plate is slidably provided in the following groove, and the following plate is fixedly connected to one side of the migration block.

[0010] The present invention is further configured such that a connecting rod is connected to one side of the connecting block, the connecting spring is movably sleeved on the outside of the connecting rod, a connecting hole is opened in the mating block, and one end of the connecting rod slides into the connecting hole.

[0011] The present invention is further configured such that a tension spring is movably sleeved on the outside of the retaining rod, and the two ends of the tension spring are respectively connected to the retaining plate and the retaining frame.

[0012] The present invention is further configured such that a sliding block is fixedly provided on the inner side of the fixing sleeve, and a sliding groove is provided on the outer side of the configuration sleeve, wherein the sliding block slides in the sliding groove.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a biochar extrusion molding machine, which has the following beneficial effects: 1. By coordinating components such as the drive assembly, configuration sleeve, configuration rod, calibration sleeve, follower sleeve, migration groove, migration plate, migration block, and configuration slot, a flexible and adjustable overload protection threshold adjustment system is constructed. This solves the technical problems of simple structure and fixed, unadjustable overload protection threshold in existing biochar extrusion molding machine overload protection devices. By rotating the calibration sleeve, the calibration sleeve drives the spiral calibration groove to rotate. Through the cooperation of the calibration groove and the calibration block, the follower sleeve pushes the migration block to move, which in turn drives the sensitive groove, sensitive spring, and configuration block to move. This achieves adjustment of the sensitive spring's thrust on the configuration block, thereby flexibly setting the threshold required for the configuration block to detach from the configuration groove. This adjustment system can adjust the overload protection threshold according to the actual usage needs such as the characteristics of different types of biomass raw materials, different production batch requirements, different product specifications, and different production environment conditions. This avoids problems such as the protection threshold being too high and unable to effectively protect equipment components, or the protection threshold being too low and frequently triggering the protection mechanism, leading to low production efficiency, thus improving the practicality and adaptability of the equipment.

[0014] 2. Through structural designs including the fit between the mating rod and the mating hole, the locking mechanism between the retaining rod and the retaining groove, the sliding limit of the sliding block and the sliding groove, the guiding fit between the connecting rod and the connecting hole, and the elastic support of the connecting spring and the mating spring, an anti-displacement locking protection system is constructed. This effectively solves the technical defects of the existing improved biochar extrusion molding machine overload protection threshold adjustment mechanism, which suffers from insufficient stability and susceptibility to external forces, leading to loosening and displacement of the adjusted components. When the appropriate protection threshold is adjusted, the retaining frame drives the retaining rod to position itself in the corresponding retaining groove. The tension spring pulls the retaining plate to insert the retaining rod into the retaining groove for locking. Simultaneously, the mating spring pushes the retaining sleeve to reset, and the connecting spring pushes the connecting block to rotate in the opposite direction, causing the mating hole and the mating groove to lock together. The misalignment of the rod and the engagement rod limit the retention sleeve to one side of the engagement plate. The movement of the retaining sleeve is further restricted by the cooperation of the moving block and the moving groove. The retention sleeve limits the retention plate, so that the retention rod and the retention groove firmly lock the retention frame and prevent the calibration sleeve from rotating accidentally. This multi-locking protection mechanism effectively resists the effects of various external forces such as continuous vibration caused by long-term operation of the equipment, impact from frequent start-stop, and accidental collisions during maintenance by operators. It ensures that the adjusted protection threshold is stable and reliable in the long term, avoids safety hazards such as irregular changes or drift of the protection threshold and failure of protection function, and effectively solves a series of adverse effects on production and economy such as raw material waste, product quality fluctuations, frequent equipment failures, and increased maintenance costs.

A configuration rod 3 is rotatably mounted inside the configuration sleeve 2. A fitting plate 4 is rotatably mounted outside the configuration sleeve 2. A retaining sleeve 5 is slidably mounted on the outside of the configuration sleeve 2. A calibration sleeve 6 is rotatably mounted on the outside of the configuration sleeve 2. A fitting hole 7 is formed on the fitting plate 4. A fitting rod 8 is fixedly connected to one side of the retaining sleeve 5. A connecting block 9 is fixedly connected to one side of the fitting plate 4. A connecting spring 10 is connected to one side of the connecting block 9. A matching block 11 is fixedly mounted on the outside of the configuration sleeve 2. The other end of the connecting spring 10 is connected to the matching block 11. A retaining sleeve 6 is fixedly mounted on one side of the calibration sleeve 6. The frame 12 has a following sleeve 13 movable inside the calibration sleeve 6. The configuration sleeve 2 has a migration groove 14 inclined inside, and a migration plate 15 is slidably arranged in the migration groove 14. A migration block 16 is fixedly connected to one side of the migration plate 15. The configuration rod 3 has a configuration groove 17 on its outer side. A fixing rod 18 is slidably arranged in the fixing frame 12. Multiple fixing grooves 19 are opened on the outer wall of the configuration sleeve 2. A fixing plate 20 is connected to one end of the fixing rod 18, and the other end of the fixing rod 18 is inserted into the fixing groove 19. A calibration block 21 is fixedly arranged on the outer side of the following sleeve 13. A calibration groove 22 is spirally opened inside the calibration sleeve 6, and the calibration block 21 slides in the calibration groove 22.

[0021] A mounting bracket 23 is provided below the drive assembly 1, and a pressing assembly 24 is provided on one side of the drive assembly 1. A pressing rod 25 is rotatably provided inside the pressing assembly 24, and one end of the pressing rod 25 is connected to the configuration rod 3.

[0022] In this embodiment, when the equipment is used for pressure molding, the raw material is first added to the extrusion assembly 24, and then the drive assembly is turned on, causing the drive assembly to rotate the configuration sleeve 2 connected to the output end. Then, the configuration sleeve 2 drives the inner migration groove 14 to rotate, and then the migration groove 14 drives the migration block 16 to rotate through the inner migration plate 15. Then, the migration block 16 drives the inner sensitive groove 26 to rotate, thereby driving the sensitive spring 27 and the configuration block 28 to rotate. Then, the configuration block 28 drives the configuration rod 3 to rotate through the configuration groove 17, causing the configuration rod 3 to drive the extrusion rod 25 to rotate. Then, the drive assembly drives... The extrusion rod 25 is extruded and formed. When the extrusion rod 25 is stuck, the configuration rod 3 and the configuration groove 17 encounter resistance, causing the inner wall of the configuration groove 17 to press against the outer wall of the configuration block 28. Due to the rounded corner design of the outer wall of the configuration block 28 and the inner wall of the configuration groove 17, the configuration block 28 slides out of the configuration groove 17 and gradually slides into the inner side of the sensitive groove 26, causing the configuration block 28 to press against the sensitive spring 27 on one side, and then causing the configuration block 28 to completely detach from the configuration groove 17, thereby causing the drive assembly to drive the configuration sleeve 2 and other components to run idle, realizing no-load protection, preventing the extrusion rod 25 from breaking, and preventing the motor in the drive assembly 1 from being overloaded and damaged.

[0023] Please see Figures 3-5As a further implementation of the overall device: a sensitive groove 26 is provided on the inner side of the migration block 16, and a sensitive spring 27 is movably provided in the sensitive groove 26. One end of the sensitive spring 27 is connected to the inner wall of the sensitive groove 26, and the other end of the sensitive spring 27 is connected to a configuration block 28, which is inserted into the configuration groove 17. A locking spring 29 is movably sleeved on the outside of the locking rod 8. One end of the locking spring 29 is connected to the retaining sleeve 5, and the other end of the locking spring 29 is in contact with the locking plate 4.

[0024] A follower groove 30 is provided on one side of the follower sleeve 13, and a follower plate 31 is slidably provided in the follower groove 30. The follower plate 31 is fixedly connected to one side of the transfer block 16.

[0025] A connecting rod 32 is connected to one side of the connecting block 9, and a connecting spring 10 is movably sleeved on the outside of the connecting rod 32. A connecting hole 33 is opened in the mating block 11, and one end of the connecting rod 32 slides into the connecting hole 33.

[0026] A tension spring 34 is movably sleeved on the outside of the retaining rod 18, and the two ends of the tension spring 34 are connected to the retaining plate 20 and the retaining frame 12 respectively.

[0027] The inner side of the fixed sleeve 5 is provided with a sliding block 35, and the outer side of the sleeve 2 is provided with a sliding groove 36, in which the sliding block 35 slides.

[0028] More specifically, when the overload protection threshold needs to be adjusted according to actual requirements, firstly, the mating plate 4 is rotated. The mating plate 4 will drive the connecting block 9 on one side to rotate forward. Then, the connecting block 9 will drive the connecting rod 32 on one side to rotate forward along the connecting hole 33. The connecting block 9 and the mating block 11 will cooperate to squeeze the connecting spring 10 sleeved on the outside of the connecting rod 32. At the same time, the mating plate 4 will drive the mating hole 7 to rotate forward. When the connecting spring 10 is squeezed to the limit, the mating hole 7 will rotate to a position concentric with the mating rod 8. Then, the retaining sleeve 5 is pushed. The retaining sleeve 5 will drive the inner sliding block 35 to slide along the sliding groove 36. The retaining sleeve 5 will also drive the mating rod 8 on one side to slide into the mating hole 7. At the same time, the retaining sleeve 5 and the mating plate 4 will cooperate to... The spring 29 compresses, causing the retaining sleeve 5 to no longer limit the outer wall of the retaining plate 20. Then, the calibration sleeve 6 rotates forward, causing one side of the retaining frame 12 to rotate forward. The retaining frame 12 then causes the retaining rod 18, the retaining plate 20, and the tension spring 34 to rotate forward. The inner wall of the retaining groove 19 compresses one end of the retaining rod 18. Due to the rounded corner design at the edge of the inner wall of the retaining groove 19, one end of the retaining rod 18 slides out of the retaining groove 19, and the other end of the retaining rod 18 causes the retaining plate 20 to slide outward, causing the retaining plate 20 to stretch the tension spring 34 outward. At the same time, the calibration sleeve 6 causes the inner spirally opened calibration groove 22 to rotate forward, and the calibration block 21 slides in the calibration groove 22. Due to the following plate... The 31 and the follower groove 30 work together to limit the rotation of the follower sleeve 13. Then, the follower sleeve 13 will drive the calibration block 21 to slide, and the follower sleeve 13 will push one side of the transfer block 16 to move. This causes the transfer block 16 to drive the sensitive groove 26, the sensitive spring 27 and the configuration block 28 to move. The transfer block 16 will also drive the other side of the transfer plate 15 to slide along the inclined transfer groove 14. This causes the transfer plate 15 to drive the transfer block 16 to converge inward. The transfer block 16 will also drive the follower plate 31 to slide inward along the follower groove 30. Then, the distance between the inner wall of the sensitive groove 26 and one side of the configuration block 28 will decrease, causing the sensitive spring 27 to be compressed to a certain extent. This increases the thrust exerted by the sensitive spring 27 on the configuration block 28, requiring the side wall of the configuration block 28 to withstand greater force. Force can disengage from the configuration slot 17 and trigger the protection threshold. When it is necessary for the configuration block 28 to disengage from the configuration slot 17 with only a small force, the calibration sleeve 6 can be rotated in the reverse direction as described above. When the appropriate protection threshold is adjusted, stop rotating the calibration sleeve 6. At this time, the retaining bracket 12 drives the retaining rod 18 and other components to rotate to the position corresponding to the retaining slot 19. Then, the tension spring 34 pulls the retaining plate 20 to slide inward, so that the retaining plate 20 drives the retaining rod 18 to slide and reset. Then, one end of the retaining rod 18 will be inserted into the corresponding retaining slot 19. Then, the retaining sleeve 5 is released, and the engagement spring 29 pushes the retaining sleeve 5 to drive the inner sliding block 35 to slide and reset along the sliding groove 36. Then, the retaining sleeve 5 drives one side engagement rod 8 to slide and reset.When the engaging spring 29 is fully reset, the engaging rod 8 no longer inserts into the engaging hole 7. At this time, the connecting spring 10 resets and pushes the connecting block 9, causing the connecting block 9 to drive one side of the connecting rod 32 to rotate and reset along the connecting hole 33. Simultaneously, the connecting block 9 will drive the engaging hole 7 to rotate to a position not corresponding to the engaging rod 8 through the engaging plate 4. Then, the engaging rod 8 will limit and support the retaining sleeve 5 to one side of the engaging plate 4. With the upstream block 35 and the sliding groove 36 limiting the retaining sleeve 5, the retaining sleeve 5 will not move. Then, the inner wall of the retaining sleeve 5 limits the outer wall of the retaining plate 20, preventing the retaining plate 20 and the retaining rod 18 from sliding outward. Then, the retaining rod 18 and the retaining groove 19 cooperate to lock the retaining frame 12, preventing the retaining frame 12 and the calibration sleeve 6 from rotating accidentally, thereby ensuring the structural stability after the protection threshold adjustment and ensuring the stable operation of the extrusion molding process.

[0029] In summary, when using or operating the entire equipment: First, when pressurization molding is required, the raw material is added to the extrusion assembly 24. Then, the drive assembly is turned on, causing the configuration sleeve 2 connected to the output end to rotate. The configuration sleeve 2 then rotates the inner migration groove 14. The migration groove 14, through the inner migration plate 15, drives the migration block 16 to rotate. The migration block 16 then drives the inner sensitive groove 26 to rotate, thereby driving the sensitive spring 27 and the configuration block 28 to rotate. The configuration block 28, through the configuration groove 17, drives the configuration rod 3 to rotate, causing the configuration rod 3 to drive the extrusion rod 25 to rotate. Then, the drive assembly... The extrusion rod 25 is driven to extrude and form the component. When the extrusion rod 25 gets stuck, the configuration rod 3 and the configuration groove 17 encounter resistance, causing the inner wall of the configuration groove 17 to press against the outer wall of the configuration block 28. Due to the rounded corner design of the outer wall of the configuration block 28 and the inner wall of the configuration groove 17, the configuration block 28 slides out of the configuration groove 17 and gradually slides into the inner side of the sensitive groove 26, causing the configuration block 28 to press against the sensitive spring 27 on one side, and then causing the configuration block 28 to completely detach from the configuration groove 17. This allows the drive assembly to drive the configuration sleeve 2 and other components to run idle, achieving no-load protection, preventing the extrusion rod 25 from breaking, and preventing the motor in the drive assembly 1 from being overloaded and damaged.

[0030] When the overload protection threshold needs to be adjusted according to actual requirements, firstly, rotate the mating plate 4. The mating plate 4 will drive the connecting block 9 on one side to rotate forward. Then, the connecting block 9 will drive the connecting rod 32 on one side to rotate forward along the connecting hole 33. The connecting block 9 and the mating block 11 will cooperate to squeeze the connecting spring 10 sleeved on the outside of the connecting rod 32. At the same time, the mating plate 4 will drive the mating hole 7 to rotate forward. When the connecting spring 10 is squeezed to the limit, the mating hole 7 will rotate to a position concentric with the mating rod 8. Then, push the retaining sleeve 5. The retaining sleeve 5 will drive the inner sliding block 35 to slide along the sliding groove 36. The retaining sleeve 5 will also drive the mating rod 8 on one side to slide into the mating hole 7. At the same time, the retaining sleeve 5 and the mating plate 4 will cooperate to squeeze the mating spring 29. Then, the retaining sleeve 5 is no longer limited by the outer wall of the retaining plate 20. Then, the calibration sleeve 6 is rotated in the forward direction. The calibration sleeve 6 will drive the retaining frame 12 on one side to rotate in the forward direction. Then, the retaining frame 12 will drive the retaining rod 18, the retaining plate 20, and the tension spring 34 to rotate in the forward direction. Then, the inner wall of the retaining groove 19 will press against one end of the retaining rod 18. Due to the rounded corner design at the edge of the inner wall of the retaining groove 19, one end of the retaining rod 18 will slide out of the retaining groove 19, and the other end of the retaining rod 18 will drive the retaining plate 20 to slide outward, causing the retaining plate 20 to drive the tension spring 34 to stretch outward. At the same time, the calibration sleeve 6 will drive the inner spirally opened calibration groove 22 to rotate in the forward direction. Then, the calibration block 21 will slide in the calibration groove 22, and due to the following plate 31 and the following groove 30 The rotation of the follower sleeve 13 is limited, and then the follower sleeve 13 drives the calibration block 21 to slide. The follower sleeve 13 also pushes one side of the transfer block 16 to move, causing the transfer block 16 to move the sensitive groove 26, the sensitive spring 27, and the configuration block 28. The transfer block 16 also causes the other side of the transfer plate 15 to slide along the inclined transfer groove 14, causing the transfer plate 15 to move the transfer block 16 inward. The transfer block 16 also causes the follower plate 31 to slide inward along the follower groove 30. Then, the distance between the inner wall of the sensitive groove 26 and one side of the configuration block 28 decreases, causing the sensitive spring 27 to be compressed to a certain extent. Then, the thrust exerted by the sensitive spring 27 on the configuration block 28 increases, so that the side wall of the configuration block 28 needs to withstand more force to move out of the configuration groove 17. When the configuration block 28 is disengaged from the configuration slot 17 and the protection threshold is triggered, and when it is necessary for the configuration block 28 to disengage from the configuration slot 17 with only a small force, the calibration sleeve 6 can be rotated in the reverse direction as described above. When the appropriate protection threshold is adjusted, the rotation of the calibration sleeve 6 is stopped. At this time, the retaining bracket 12 drives the retaining rod 18 and other components to rotate to the position corresponding to the retaining slot 19. Then, the tension spring 34 pulls the retaining plate 20 to slide inward, so that the retaining plate 20 drives the retaining rod 18 to slide and reset. Then, one end of the retaining rod 18 will be inserted into the corresponding retaining slot 19. Then, the retaining sleeve 5 is released, and the engaging spring 29 pushes the retaining sleeve 5 to drive the inner sliding block 35 to slide and reset along the sliding groove 36. Then, the retaining sleeve 5 drives one side of the engaging rod 8 to slide and reset. When the engaging spring 29 is fully reset,When the engaging rod 8 no longer inserts into the engaging hole 7, the connecting spring 10 resets and pushes the connecting block 9, causing the connecting block 9 to rotate and reset one side of the connecting rod 32 along the connecting hole 33. Simultaneously, the connecting block 9, through the engaging plate 4, causes the engaging hole 7 to rotate to a position not corresponding to the engaging rod 8. Then, the engaging rod 8 limits and supports the retaining sleeve 5 to one side of the engaging plate 4. Combined with the upstream block 35 and the sliding groove 36 limiting the retaining sleeve 5, the retaining sleeve 5 will not move. Then, the inner wall of the retaining sleeve 5 limits the outer wall of the retaining plate 20, preventing the retaining plate 20 and the retaining rod 18 from sliding outwards. Then, the retaining rod 18 and the retaining groove 19 cooperate to lock the retaining frame 12, preventing the retaining frame 12 and the calibration sleeve 6 from rotating accidentally, thus ensuring the structural stability after the protection threshold adjustment and ensuring the stable operation of the extrusion molding process.
