Description

Technical Field

[0001] This invention relates to the field of resin granulation technology, specifically to a resin granulation device capable of rapid cooling. Background Technology

[0002] Resins generally soften or melt when heated, and are solid or semi-solid organic polymers at room temperature. Resin granules are made by processing powdered resin into granules using chemical granulation equipment. The processed resin granules are then bagged and stored for later use.

[0003] The process of processing resin granules mainly involves melting and extruding the resin, then cutting the extruded resin strips into granules using a cutter. Since the resin granules are at a high temperature, they need to be transported to a cooling device for air cooling. The cooled resin granules are then collected to complete the production of resin granules.

[0004] The cut resin granules fall directly onto the conveyor belt, and gradually accumulate on the belt during the continuous falling process. As the accumulated resin granules move with the conveyor belt and are cooled, the following situations are likely to occur: First, if the resin granules are already in an accumulated state and are kept in a static state to receive cooling, the resin granules in both states are more difficult to cool quickly, and the degree of uneven cooling inside and outside is further increased. The resin granules that cannot be dispersed in time are prone to sticking together with each other and between the resin granules and the conveyor belt.

[0005] 2. In a resin particle pile, the outermost resin particles cool first, followed by the inner layers. Due to the uneven cooling of the inner and outer layers, when the outer layer cools to a certain temperature, the inner layer is still at a higher temperature, and the heat cannot be dissipated in time. This makes it easier for the resin particles in the inner layer to stick together. Because there are more of them, the clumps are larger, making it more difficult to cool quickly in the future and harder to separate and use again. Summary of the Invention

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a resin granulation device capable of rapid cooling, comprising a support frame, on which a granulator is fixedly mounted, a granulation conveying mechanism is provided on the right side of the granulator, a granulation cooling mechanism is provided on the right side of the granulation conveying mechanism, and fans are installed at both the front and rear ends of the granulation cooling mechanism.

[0007] The particle conveying mechanism includes an outer cover, the lower end of which is fixedly connected to the upper end of a support frame. Two symmetrically arranged connecting drive units are disposed inside the outer cover. Two remote rods are symmetrically arranged between the two connecting drive units, and multiple top members are fixedly connected between the two remote rods. A particle screening unit is slidably connected between the outer sides of the connecting drive units. The top members are located inside the particle screening unit. A support block is installed in the middle of the inner side of the particle screening unit. The front and rear ends of the support block are fixedly connected to the inner wall of the outer cover. A blocking filter unit is also disposed on the upper side of the particle screening unit and directly above the support block.

[0008] Furthermore, the connection drive unit includes a roller shaft, the end of the remote rod is rotatably connected to the roller shaft and the rotation point of the remote rod is offset from the axis of the roller shaft, and slots are provided at both the front and rear ends of the roller shaft. A positioning rod is slidably connected in the slots, and both the front and rear ends of the positioning rod are fixedly connected to the inner wall of the outer cover.

[0009] Furthermore, the particle screening unit includes a conveyor belt, the inner side of which is slidably connected to the outer side of the roller shaft, and multiple partitions are fixedly connected to the outer side of the conveyor belt. Multiple dividing grooves are formed on the conveyor belt and between two adjacent partitions, and the inner diameter of the dividing grooves is larger than that of the resin particles.

[0010] Furthermore, the blocking and filtering unit includes a fixed block, the lower end of which is rotatably connected to a roller, the lower side of which is close to the conveyor belt, and the end of the roller and the ends of two roller shafts on the same side are connected together by a transmission belt.

[0011] Furthermore, the particle cooling mechanism includes a placement box, the lower end of which is fixedly connected to the upper end of the support frame. A cavity is opened inside the placement box, and a filter plate is fixedly connected to the upper side of the inner wall of the cavity. A dispersion collection unit is installed on the inner wall of the cavity and below the filter plate. A transition groove is opened on the left side of the placement box along the front-back direction. A ventilation opening is opened inside the placement box, and the ventilation opening connects the cavity and the fan. A collection box is fixedly connected to the lower end of the placement box.

[0012] Furthermore, the dispersed collection unit includes a support column, the lower end of which is rotatably connected to the placement box, and a conical guide block is fixedly connected to the upper end of the support column. Multiple stirring rods are fixedly connected to the outer side of the support column, and the surface of the stirring rods is covered with rubber.

[0013] Furthermore, the left side of the transition groove is connected to the inside of the outer cover, the right side of the transition groove is connected to the inside of the cavity, and the openings on both the left and right sides of the transition groove face upwards.

[0014] The beneficial effects of the present invention are as follows: First, the present invention, through the cooperation between the connecting drive unit, the remote rod and the top part, causes the upper side of the particle screening unit to vibrate, so that the resin particles are always in motion. This avoids the resin particles from accumulating, which would lead to uneven cooling inside and outside, large temperature difference, and adhesion between resin particles and between resin particles and the particle screening unit. It also allows the resin particles to disperse on their own, complete the initial spreading, and facilitate subsequent rapid cooling.

[0015] Second, this invention utilizes the barrier filter unit in conjunction with the vibration of the top component to perform joint operation on the upper and lower layer resin particles, avoiding the upper layer resin particles from being constantly piled up and having a high degree of internal adhesion, so that the resin particles are flat and evenly dispersed, which facilitates subsequent rapid cooling and uniform cooling. At the same time, the barrier filter unit continuously turns the resin particles over, preventing the resin particles from getting stuck at the barrier filter unit.

[0016] Third, this invention uses a blower to blow air into the cavity to quickly cool the resin particles inside the cavity. At the same time, the dispersion and collection unit rotates to beat and disperse the resin particles inside the cavity, so that the resin particles that were originally stuck together in small areas can be separated. The rubber wrapped around the stirring rod can buffer and protect the resin particles, preventing hard collisions between the stirring rod and the resin particles, which would cause the resin particles to be crushed.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1 A resin granulation device capable of rapid cooling includes a support frame 1, on which a granulator 2 is fixedly installed. A granulation conveying mechanism 3 is arranged on the right side of the granulator 2, and a granulation cooling mechanism 4 is arranged on the right side of the granulation conveying mechanism 3. Fans 5 are installed at both the front and rear ends of the granulation cooling mechanism 4.

[0026] The resin is processed into granules by the granulator 2. The granulated resin falls onto the granule conveying mechanism 3 and is then conveyed to the granule cooling mechanism 4. During the conveying process, the resin granules are vibrated to prevent them from softening and sticking due to high temperature. After being conveyed to the granule cooling mechanism 4, the fan 5 blows air into the granule cooling mechanism 4, so that the resin granules inside the granule cooling mechanism 4 are cooled by the high-pressure air blown by the fan 5.

[0027] Please see Figure 1 and Figure 2The particle conveying mechanism 3 includes an outer cover 31, the lower end of which is fixedly connected to the upper end of the support frame 1. Two symmetrical connecting drive units 32 are arranged inside the outer cover 31. Two remote rods 33 are symmetrically arranged between the two connecting drive units 32. Multiple top pieces 34 are fixedly connected between the two remote rods 33. A particle screening unit 35 is slidably connected between the outer sides of the connecting drive units 32. The top pieces 34 are located inside the particle screening unit 35. A support block 36 is installed in the middle of the inner side of the particle screening unit 35. The front and rear ends of the support block 36 are fixedly connected to the inner wall of the outer cover 31. A blocking filter unit 37 is arranged on the upper side of the particle screening unit 35 and directly above the support block 36.

[0028] The resin granules processed by granulator 2 fall onto the upper side of the granule screening unit 35. An external drive drives the granule screening unit 35 to move via the connecting drive unit 32. The granule screening unit 35 carries the resin granules into the granule cooling mechanism 4 on the right. During the conveying process of the granule screening unit 35, the connecting drive unit 32 drives the remote rod 33 to move up and down continuously, which in turn drives the top part 34 to move up and down continuously. When the top part 34 moves, it comes into contact with the granule screening unit 35 and generates collision vibration, thereby vibrating the resin granules on the granule screening unit 35, so that the resin granules are in motion and dispersed, reducing the adhesion rate of the resin granules. When the granule screening unit 35 carries the resin granules to the blocking filter unit 37, the blocking filter unit 37 controls the amount of resin granules transported under the drive of the connecting drive unit 32 to prevent too many resin granules from entering the granule cooling mechanism 4 per unit time, which would affect the cooling rate of the resin granules by the granule cooling mechanism 4.

[0029] Please see Figure 2 and Figure 3 The connecting drive unit 32 includes a roller shaft 321, the end of a remote rod 33 is rotatably connected to the roller shaft 321 and the rotation point of the remote rod 33 is offset from the axis of the roller shaft 321, and slots 322 are provided at both the front and rear ends of the roller shaft 321. A positioning rod 323 is slidably connected in the slots 322, and both the front and rear ends of the positioning rod 323 are fixedly connected to the inner wall of the outer cover 31.

[0030] Please see Figure 2 and Figure 3The particle screening unit 35 includes a conveyor belt 351, the inner side of the conveyor belt 351 is slidably connected to the outer side of the roller 321, and multiple partitions 352 are fixedly connected to the outer side of the conveyor belt 351. Multiple dividing grooves 353 are opened on the conveyor belt 351 and between two adjacent partitions 352. The inner diameter of the dividing grooves 353 is larger than the size of the resin particles. An external drive rotates the roller 321 clockwise, which in turn moves the conveyor belt 351 to transport the resin particles. Initially, the lever 33 is horizontal, with its two ends located to the left of the axis of its respective roller 321. As the roller 321 rotates, it drives the lever 33 to move up and down continuously. The lever 33 then drives the top member 34 to move up and down continuously. During the up-and-down movement, the top member 34 continuously impacts the conveyor belt 351, keeping the resin particles on the upper side of the conveyor belt 351 in a state of vibration and dispersion. Compared to the resin particles being transported in a pile on the conveyor belt 351, the particle screening unit 35 can effectively prevent the resin particles from sticking together into clumps or adhering to the surface of the conveyor belt 351, reducing the waste rate of resin particles, increasing the molding material of independently hardened resin particles, and ensuring the continuous and smooth transport of resin particles and the cleanliness of the surface of the conveyor belt 351.

[0031] Please see Figure 1 , Figure 2 and Figure 4 The blocking and filtering unit 37 includes a fixing block 371, and a roller 372 is rotatably connected to the lower end of the fixing block 371. The lower side of the roller 372 is close to the conveyor belt 351. A transmission belt 373 is connected between the end of the roller 372 and the ends of two roller shafts 321 on the same side.

[0032] When the resin particles are transported by the conveyor belt 351, the top member 34 continuously impacts the conveyor belt 351 during its up-and-down movement. The resin particles on the conveyor belt 351 are vibrated, causing the resin particles at the bottom layer to enter the dividing groove 353 with the vibration, thus completing the flat distribution of the bottom layer resin particles. At the same time, the roller 321 drives the transmission belt 373 to move, and the movement of the transmission belt 373 drives the drum 372 to rotate clockwise. When the resin particles are transported to the position of the drum 372, the drum 372 can continuously turn over the resin particles that are still in a certain state of accumulation on the top layer, so that the accumulated resin particles are flat on the conveyor belt 351. The flat resin particles pass under the drum 372 and continue to be transported to the right. By using the vibration of the drum 372 in conjunction with the top member 34, the upper and lower layers of resin particles are operated together, avoiding the upper layer of resin particles from always being in a state of accumulation and having a high degree of internal adhesion, so that the resin particles are flat and evenly dispersed, which facilitates subsequent rapid cooling and uniform cooling.

[0033] Please see Figure 1 and Figure 5 The particle cooling mechanism 4 includes a placement box 41, the lower end of which is fixedly connected to the upper end of the support frame 1. A cavity 42 is opened inside the placement box 41. A filter plate 43 is fixedly connected to the upper side of the inner wall of the cavity 42. A dispersion collection unit 44 is installed on the inner wall of the cavity 42 and below the filter plate 43. A transition groove 45 is opened on the left side of the placement box 41 along the front-back direction. A ventilation port 46 is opened inside the placement box 41. The ventilation port 46 connects the cavity 42 and the fan 5. A collection box 47 is fixedly connected to the lower end of the placement box 41. The left side of the transition groove 45 is connected to the inside of the outer cover 31, and the right side of the transition groove 45 is connected to the inside of the cavity 42. The openings on both sides of the transition groove 45 face upward.

[0034] When the resin particles are conveyed to the far right of the conveyor belt 351, they fall downwards into the left side of the transition trough 45 and are temporarily stored inside the transition trough 45. Then, the fan 5 blows air into the particle cooling mechanism 4, causing the air inside the cavity 42 to flow at high speed through the vent 46. The high-speed airflow in the cavity 42 generates suction, continuously drawing the resin particles from the transition trough 45 into the cavity 42. The air flowing in the cavity 42 continuously exchanges heat with the resin particles, thus completing the cooling of the resin particles. At the same time as the resin particles enter the cavity 42, the external drive drives the dispersion... The collecting unit 44 rotates, and the rotating dispersing collecting unit 44 comes into contact with the resin particles, applying a lateral force to the resin particles, prolonging the residence time of the resin particles in the cavity 42, so that the resin particles have a better cooling effect. During the cooling process, the resin particles move upward with the air flowing in the cavity 42. When they reach the air filter plate 43, the resin particles are intercepted. After cooling is completed, the upper end of the collecting box 47 is manually opened to connect the collecting box 47 with the cavity 42, and the vent 46 is closed. The resin particles in the cavity 42 fall into the collecting box 47 under the action of gravity and are collected.

[0035] Please see Figure 5 and Figure 6 The dispersed collection unit 44 includes a support column 441, the lower end of which is rotatably connected to the placement box 41, a conical guide block 442 is fixedly connected to the upper end of the support column 441, and multiple stirring rods 443 are fixedly connected to the outside of the support column 441, with the surface of the stirring rods 443 covered with rubber.

[0036] During the rotation of the dispersion collection unit 44, the supporting column 441 drives the stirring rod 443 to rotate. The stirring rod 443 comes into contact with the resin particles, thereby dispersing the resin by tapping, which separates the resin particles that were originally stuck together in small areas. The rubber wrapped around the stirring rod 443 can buffer and protect the resin particles, preventing hard collisions between the stirring rod 443 and the resin particles, which would cause the resin particles to shatter. The dispersed resin particles are cooled and move upward under the action of the wind in the cavity 42, and are eventually blocked by the air filter plate 43. When the vent 46 is closed, the resin particles fall downward along the guide block 442. The guide block 442 plays a guiding role for the resin particles in this process.

[0037] Working principle: The resin is processed into granules by the granulator 2. The granulated resin falls onto the upper end of the granule conveying mechanism 3 and is conveyed to the inside of the granule cooling mechanism 4. During the conveying process of the granule conveying mechanism 3, the resin granules are vibrated to prevent the resin granules from softening and sticking due to high temperature before conveying. After being conveyed into the granule cooling mechanism 4, the fan 5 blows air into the granule cooling mechanism 4, so that the resin granules inside the granule cooling mechanism 4 are cooled by the high pressure of the fan 5.
