Description

Technical Field

[0001] This invention belongs to the technical field of crushing and granulation, specifically relating to a DH1250 granulation production line. Background Technology

[0002] During the granulation process, after the molten material is extruded through the die to form a strip, it is prone to clumping and blockage in the discharge path due to material residue, temperature fluctuations, or impurity accumulation. This not only causes production interruptions but also requires shutdown for cleaning, severely impacting production efficiency. Existing granulation production lines often employ a single pushing or sweeping method for deblocking, which suffers from incomplete cleaning, the need for shutdown operations, and the risk of pushing solidified blockage material into the equipment during cleaning, causing secondary blockages and further reducing production continuity.

[0003] Meanwhile, the extruded strips usually go directly into the subsequent crushing process. Due to the long length and strong toughness of the strips, existing crushing equipment mostly relies on single-stage cutting or crushing structures, which results in low crushing efficiency and strips wrapping around the blades. Additional pre-treatment equipment is required to ensure the crushing effect, which increases equipment investment and production process complexity.

[0004] While some existing technologies attempt to integrate anti-blocking and crushing functions, they generally suffer from unreasonable structural design: either the deblocking operation and granulation production cannot be synchronized, or the preliminary crushing effect is poor, making it difficult to meet the high-efficiency requirements of continuous granulation production. Furthermore, the deblocking structure is complex and prone to damage, leading to limited overall production efficiency and increased equipment maintenance costs. Therefore, there is an urgent need for an integrated technical solution that can achieve efficient and synchronous deblocking and rapid preliminary crushing of the material strips to address the core pain points of existing granulation production lines. Summary of the Invention

[0005] The purpose of this invention is to provide a DH1250 granulation production line to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a DH1250 granulation production line, including crushing and granulation equipment, wherein the crushing and granulation equipment includes a forced feeder drive, two forced feeders, a double pressure roller cavity, a bolt removal mechanism, a drum gear coupling, a main motor, a diaphragm coupling, a reducer, a hydraulic station, and a feed inlet; a hopper is integrally formed above the double pressure roller cavity, and the feed inlets of the two forced feeders both lead to the top of the hopper and are arranged opposite to each other; the bolt removal mechanism includes an energy-saving motor, an output shaft, a reciprocating shaft, a pusher plate, and a cylinder; and the double pressure roller cavity has a hopper integrally formed on the upper left and right sides. The hopper has an integrally formed support plate. The energy-saving motor is fixedly installed on the right side of the right support plate by bolts. The cylinder is integrally formed on the right side of the left support plate. The output shaft is rotatably connected to the right support plate and fixedly connected to the output end of the energy-saving motor. The hopper has through holes on both sides, and the reciprocating shaft is slidably connected in the through holes. The reciprocating shaft and the output shaft are interconnected. The push plate is integrally formed on the left end of the reciprocating shaft and rotatably connected to the cylinder. The reciprocating shaft is rotatably connected to the middle of the reciprocating shaft, and bolt-removing shafts are bolted to both ends of the pin. The bolt-removing shafts are located inside the hopper.

[0007] The present invention further describes that the left end of the output shaft is provided with a slot, the right end of the reciprocating shaft is provided with a rod, and the rod is slidably connected to the groove of the output shaft. The inner wall of the slot is provided with a snap-fit ​​block, and the outer wall of the rod is provided with a snap-fit ​​groove, which snaps into the snap-fit ​​block. The outer wall of the cylinder is provided with two inclined grooves facing each other, and the two ends of the two inclined grooves are connected to a connecting groove. The left end of the push plate is rotatably connected to two rollers, and the two rollers are arranged opposite each other. The rollers are embedded in the inclined grooves and the connecting grooves.

[0008] The present invention further illustrates that a hydraulic hole is provided in the middle of the cylinder, and a plug is provided at the left end of the hydraulic hole, and a push rod is slidably connected to the right end. A sliding hole is connected between the push plate and the reciprocating shaft, and the right side of the push rod is slidably connected to the sliding hole.

[0009] The present invention further illustrates that the outer ring of the right end of the plug and the outer ring of the left end of the push rod are both provided with sealing rings for sealing, and hydraulic oil is filled between them.

[0010] The present invention further illustrates that the left side of the plug is threaded and threadedly connected to the left support plate. The left end of the plug is provided with an internal hexagonal hole and is used in conjunction with an internal hexagonal wrench.

[0011] The present invention further illustrates that the middle part of the pin is square, and the square part is located inside the sliding hole.

[0012] The present invention further illustrates that, after the top rod is subjected to force, its right end fits into contact with the left side of the square portion of the pin.

[0013] The present invention further explains that the operation steps of the crushing and granulation equipment include: Step S1, the raw material is fed into the equipment through the feed port, the forced feeder is started and driven, the raw material is forcibly conveyed by the forced feeder, the raw material enters the double pressure roller cavity through the hopper, and at the same time the unblocking mechanism cleans the blockage in the raw material, then the main motor is started, and the power is transmitted to the reducer in sequence through the drum gear coupling and the diaphragm coupling, and after reduction and torque increase, the pressure rollers in the double pressure roller cavity are driven to rotate; Step S2, under the high pressure provided by the hydraulic station, the raw material is pressed into a dense strip, the core components such as the pressure roller are cooled during the process, the pressed strip is discharged from the equipment, and then crushed, screened, shaped and other subsequent processes are carried out to finally obtain a granular product with uniform specifications.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: When the crushing and granulation equipment of the present invention experiences blockage during discharge, the reciprocating shaft rotates via an energy-saving motor, which drives the unblocking shaft to rotate around the center through a pin. This agitates the blocked material strips, clears the hopper, improves the discharge efficiency of the material strips, and prevents the granulation process from being interrupted due to blockage. The connection between the unblocking shaft and the reciprocating shaft via the pin allows the unblocking shaft to be subjected to resistance and compression from the material strips during rotation. This enables the unblocking shaft to automatically swing when resetting, allowing it to stagger the compression within the material strips, thereby further improving the unblocking effect. Furthermore, the energy-saving motor... The motor operates only when a blockage occurs, thus relatively reducing energy consumption and achieving energy saving. During the unblocking process, the reciprocating shaft rotates, driving two rollers to rotate around its center via the push plate. This causes the rollers to roll in the inclined chute and be subjected to the axial force applied by the inclined chute, thereby pulling the reciprocating shaft to move to the left. Through the pin, the unblocking shaft rotates and moves to the left, fully agitating the material strips in the hopper and unblocking at the fastest speed, ensuring a continuous supply of material strips and thus accelerating production efficiency. The overall unblocking system adopts a simple structure and low manufacturing cost, making it applicable to all crushing and granulation equipment.

[0015] When the roller rolls in the inclined chute and is pulled to the left by the axial force, the pusher moves to the left. The hydraulic oil is squeezed by the push rod, generating a reverse force. When the roller rolls to the position of the connecting groove, it loses the support of the inclined chute. The reaction force generated by the hydraulic oil pushes the push rod to quickly reset, thereby driving the bolt-removing shaft to move quickly to the right through the reciprocating shaft. This impacts, grinds, and crushes the material strips, which not only further improves the unblocking strength but also performs preliminary crushing of the material strips, thereby accelerating subsequent production efficiency. At the same time, when the roller rolls in the inclined chute, the energy-saving motor is in a power-accumulating process. When the roller rolls to the position of the connecting groove, the power accumulation ends, allowing the bolt-removing shaft to quickly reset and impact. During this process, the energy-saving motor only needs to provide the energy consumed during power accumulation. Compared to controlling the speed of the energy-saving motor to increase the energy consumption required for the bolt-removing shaft to agitate and crush the material strips, the energy consumption is lower, the production cost is reduced, and the energy-saving effect is better.

[0025] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-7 The present invention provides a technical solution: a DH1250 granulation production line, including crushing and granulation equipment, the crushing and granulation equipment including a forced feeder drive, two forced feeders 2, a double pressure roller cavity 3, a bolt removal mechanism, a drum gear coupling, a main motor, a diaphragm coupling, a reducer, a hydraulic station, and a feed inlet;

[0027] A hopper 31 is integrally formed above the double pressure roller cavity 3. The feeding ports of the two forced feeders 2 both lead to the top of the hopper 31 and are arranged opposite each other. The bolt release mechanism includes an energy-saving motor, an output shaft 32, a reciprocating shaft 33, a push plate 34, and a cylinder 35. Support plates are integrally formed on both the left and right sides above the double pressure roller cavity 3. The energy-saving motor is fixedly installed on the right side of the right support plate by bolts. The cylinder 35 is integrally formed on the right side of the left support plate. The output shaft 32 is rotatably connected to the right support plate. Inside the side support plate, and fixedly connected to the output end of the energy-saving motor, the left and right sides of the hopper 31 are provided with through holes, and the reciprocating shaft 33 is slidably connected in the through holes. The reciprocating shaft 33 and the output shaft 32 are connected to each other. The push plate 34 is integrally formed on the left end of the reciprocating shaft 33 and is rotatably connected to the cylinder 35. The middle of the reciprocating shaft 33 is rotatably connected with the pin 331, and the front and rear ends of the pin 331 are bolted with the bolt-removing shaft 332. The bolt-removing shaft 332 is located inside the hopper 31.

[0028] The material strip is fed into the hopper 31 by the forced feeder 2 and then falls into the double pressure roller cavity 3. When the hopper 31 is blocked, the energy-saving motor runs and drives the reciprocating shaft 33 to rotate through the output shaft 32. The rotation of the reciprocating shaft 33 drives the unblocking shaft 332 to rotate around the center through the pin 331, which agitates the blocked material strip, clears the hopper 31, improves the discharge efficiency of the material strip, and avoids the interruption of granulation work due to blockage. The unblocking shaft 332 is connected to the reciprocating shaft 33 through the pin 331, so that the unblocking shaft 332 is subjected to the resistance and compression of the material strip when it rotates, so that the unblocking shaft 332 can swing automatically when it returns to its original position, which can stagger the compression in the material strip, thereby further improving the unblocking effect. By setting the energy-saving motor, it only runs when blockage occurs, thereby relatively reducing energy consumption and achieving energy saving.

[0029] The overall de-emulsification system has a simple structure, low manufacturing cost, and can be applied to all crushing and granulation equipment.

[0030] The left end of the output shaft 32 is provided with a slot, and the right end of the reciprocating shaft 33 is provided with a rod, which is slidably connected to the groove of the output shaft 32. The inner wall of the slot is provided with a snap-fit ​​block, and the outer wall of the rod is provided with a snap-fit ​​groove, which is snapped into the snap-fit ​​block. The outer wall of the cylinder 35 is provided with two inclined grooves 351 facing each other, and the two ends of the two inclined grooves 351 are connected with a connecting groove 352. The left end of the push plate 34 is rotatably connected with two rollers 341, and the two rollers 341 are arranged opposite each other. The rollers 341 are embedded in the inclined grooves 351 and the connecting grooves 352.

[0031] During the unblocking process, the reciprocating shaft 33 rotates, driving two rollers 341 to rotate around its center via the push plate 34. This causes the rollers 341 to roll within the inclined groove 351 and be subjected to the axial force applied by the inclined groove 351, thereby pulling the reciprocating shaft 33 to move to the left. The insertion rod at the right end of the reciprocating shaft 33 is connected to the snap-fit ​​block via the snap-fit ​​groove, allowing the output shaft 32 to both drive the reciprocating shaft 33 to rotate and smoothly move to the left. As the reciprocating shaft 33 rotates and moves to the left, the pin 331 drives the unplugging shaft 332 to rotate and move to the left, fully agitating the material strips in the hopper 31 to unblock the flow at the fastest speed, ensuring a continuous supply of material strips and thus accelerating production efficiency.

[0032] A hydraulic hole is provided in the middle of the cylinder 35, and a plug 353 is provided at the left end of the hydraulic hole. A push rod 354 is slidably connected to the right end. A sliding hole is connected between the push plate 34 and the reciprocating shaft 33, and the right side of the push rod 354 is slidably connected in the sliding hole.

[0033] Both the outer ring of the right end of the plug 353 and the outer ring of the left end of the push rod 354 are equipped with sealing rings for sealing, and hydraulic oil is filled between them.

[0034] When the roller 341 rolls in the inclined groove 351 and is pulled to the left by the axial force, the push plate 34 moves to the left. The push plate 34 drives the push rod 354 to move to the left. The push rod 354 slides in the hydraulic hole of the cylinder 35, squeezing the hydraulic oil and generating a reverse force. When the roller 341 rolls to the position of the connecting groove 352, it loses the support of the inclined groove 351. The reaction force generated by the hydraulic oil pushes the push rod 354 to quickly reset. This drives the unblocking shaft 332 to move quickly to the right through the reciprocating shaft 33, impacting, grinding and crushing the material strip. This can further improve the unblocking strength and perform preliminary crushing of the material strip, thereby accelerating the subsequent production efficiency.

[0035] Meanwhile, when the roller 341 rolls in the inclined groove 351, the energy-saving motor is in a power-accumulating process. When the roller 341 rolls to the position of the connecting groove 352, the power accumulation ends, which allows the bolt-removing shaft 332 to quickly reset and impact. During this process, the energy-saving motor only needs to provide the energy consumption during power accumulation. Compared with controlling the speed of the energy-saving motor, which increases the energy consumption required for the bolt-removing shaft 332 to agitate and crush the material strip, the energy consumption is lower, the production cost is reduced, and the energy-saving effect is better.

[0036] By setting sealing rings on the outer rings of the plug 353 and the push rod 354, a sealing effect can be achieved, thereby ensuring the strength of the force applied by the hydraulic oil and preventing hydraulic oil leakage.

[0037] The left side of the plug 353 is threaded and is threaded into the left support plate. The left end of the plug 353 is provided with an internal hexagonal hole and is used with an internal hexagonal wrench.

[0038] Roller 341 rolls within inclined groove 351, and push rod 354 compresses hydraulic oil to store force. To improve the impact crushing strength of the material strip, the operator can insert an Allen wrench into the Allen hole of plug 353 and turn plug 353 to move it to the right through threaded transmission. Plug 353 compresses the hydraulic oil to increase the initial hydraulic oil pressure, thereby increasing the force exerted on push rod 354 when compressing the hydraulic oil, thus improving the crushing strength of the material strip. The operation is convenient, and the crushing strength is controllable. On the one hand, it improves the crushing effect of the material strip; on the other hand, it reduces the impact strength due to the low hardness of the material strip, further reducing the energy consumption of the energy-saving motor, reducing structural wear, and improving the service life of the structure.

[0039] The middle part of the pin 331 is square, and the square part is located inside the sliding hole.

[0040] After the push rod 354 is subjected to force, its right end fits against the left side of the square part of the pin 331.

[0041] The reciprocating shaft 33 moves to the left, driving the unscrewing shaft 332 to agitate and squeeze the material strip through the pin 331. At this time, the push rod 354 is affected by the hydraulic oil force and slides in the sliding hole. The right end of the push rod 354 presses against the square part of the pin 331, thereby restricting the pin 331. At this time, the unscrewing shaft 332 cannot rotate around the center of the pin 331 through the pin 331, thereby improving the stability when squeezing and agitating the material strip and improving the unblocking effect.

[0042] When the reciprocating shaft 33 moves to the right to reset, the unblocking shaft 332 changes from vertical to horizontal. At the same time, the reaction force on the push rod 354 decreases, reducing the limiting strength on the square part of the pin 331. When the unblocking shaft 332 moves to the right, it is squeezed by the material strip and will swing clockwise or counterclockwise through the pin 331. At this time, since the two forced feeders 2 respectively feed the material strip into the hopper 31 from the front and rear sides of the reciprocating shaft 33, if the material strip on the front or rear side is severely blocked, the unblocking shaft 332 will be subjected to a large squeezing force from the material strip, thus causing it to deviate and become tilted. The unblocking shaft 332 on the front or rear side is squeezed by the material strip, while the blocked part on the other side has been cleared. Because the unblocking shaft 332 on that side is tilted, the opening surface of the hopper 31 on that side is larger, thereby increasing the discharge speed on that side. Only the severely blocked side is subjected to high-intensity crushing and squeezing, which is adaptive and results in better unblocking effect.

[0043] The operation steps of the crushing and granulation equipment include: Step S1, the raw material is fed into the equipment through the feed port, the forced feeder is started and driven, the forced feeder 2 forces the raw material to be conveyed, the raw material enters the double pressure roller cavity 3 through the hopper 31, and at the same time the unblocking mechanism cleans the jammed objects in the raw material. Then the main motor is started, and the power is transmitted to the reducer in sequence through the drum gear coupling and the diaphragm coupling. After the reduction and torque increase, the pressure rollers in the double pressure roller cavity 3 are driven to rotate.

[0044] Step S2: Under the high pressure provided by the hydraulic station, the raw material is pressed into a dense strip. During the process, the core components such as the pressure roller are cooled. The pressed strip is discharged from the equipment and then crushed, screened, shaped and other subsequent processes to finally obtain a uniformly sized granular product.
