Cooling pool for nylon plastic particle production

Abstract

This utility model belongs to the field of plastic particle production technology, specifically a cooling tank for nylon plastic particle production. It includes a drive motor, an incomplete gear mounted on the output end of the drive motor, and an installation cavity between the two sides of a sliding block. Six teeth are equidistantly mounted on the inner walls of both sides of the top of the installation cavity. Three stirring blades are equidistantly mounted on the bottom of the rotating shaft, and stirring plates are mounted on the outer side of the connecting shaft. The drive motor drives the incomplete gear to rotate, and through alternating meshing with the teeth, pushes the installation cavity to slide along the slide groove, causing the stirring assembly to perform a small-range reciprocating motion in the horizontal direction. Simultaneously, the stirring motor drives the rotating shaft and stirring blades to rotate, stirring the coolant and particles. When the rotating shaft rotates, it not only drives the connecting plate to make the stirring blades perform circumferential motion, but also, through the meshing of the driving gear and the driven gear, causes the stirring blades to rotate. These three elements work together to enhance the relative motion between the particles and the coolant, improve heat exchange efficiency, and ensure uniform cooling.

Description

Technical Field

[0001] This utility model relates to the field of plastic particle production technology, specifically a cooling tank for the production of nylon plastic particles. Background Technology

[0002] During the production of nylon plastic pellets, the internal temperature of the plastic pellets is high after extrusion and cutting. If they are not cooled in time, the pellets will become viscous due to the high temperature and tend to stick together to form clumps, which will affect the appearance of the pellets. Therefore, a cooling tank is required.

[0003] A Chinese patent with authorization announcement number CN221314800U discloses a cooling tank for the production of modified nylon 66 plastic particles. The tank includes a cooling tank body, a placement groove disposed on the upper surface of the cooling tank body, and a placement net embedded inside the placement groove. Connecting rings are welded to both sides of the upper surface of the placement net. Two sliding grooves are provided on each of the two opposite surfaces inside the placement groove, and sliders are welded to each of the two opposite surfaces of the placement net. The positions of the two sliders are adapted to the positions of the sliding grooves. This invention, through its placement net structure, facilitates centralized cooling of plastic particles within the cooling tank body. Simultaneously, the connecting rings, traction rope, and drive motor structure facilitate the lifting and lowering of the placement net, thereby enabling centralized collection of the cooled plastic particles, facilitating subsequent processing and improving the working efficiency of the device.

[0004] However, the aforementioned cooling pool still has some problems. In practical applications, when the particles are cooled, they are usually placed statically in the cooling pool. The rate at which heat is transferred from the particle surface to the coolant will slow down, reducing the cooling efficiency. Furthermore, the accumulation of particles leads to poor local cooling effect, affecting the overall cooling quality. Therefore, a cooling pool for the production of nylon plastic particles is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems mentioned in the background art, this utility model proposes a cooling pool for the production of nylon plastic particles.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A cooling pool for the production of nylon plastic particles, comprising a pool body, an mounting block installed on the top of the pool body, an mounting frame installed on the bottom side of the mounting block, a drive motor installed on the top inner wall of the mounting frame, an incomplete gear installed at the output end of the drive motor, sliding grooves opened on both sides of the mounting frame, sliding blocks slidably installed inside the sliding grooves, and a mounting cavity jointly installed between the two sides of the sliding blocks. Six teeth are equidistantly installed on the inner walls of both sides of the top of the mounting cavity, and the incomplete gear meshes with the teeth on one side during operation. A stirring motor is installed on the bottom side of the mounting cavity. A rotating shaft is installed at the output end of the mixer motor. Three stirring blades are equidistantly installed at the bottom end of the rotating shaft. A drive gear is installed at the top end of the rotating shaft. A connecting plate is installed at the top end of the rotating shaft. Connecting shafts are rotatably installed inside both ends of the connecting plate. Three sets of stirring blades, each consisting of three blades, are equidistantly installed on the outer side of the connecting shaft. A driven gear is installed at the top end of each connecting shaft. The drive gear and the driven gear mesh with each other. Through the alternating meshing of the incomplete gears and teeth, the stirring assembly reciprocates within a small range in the horizontal direction. At the same time, the stirring blades rotate synchronously with the stirring plate, effectively enhancing the relative motion between the particles and the coolant, improving heat exchange efficiency, reducing particle accumulation dead zones, and ensuring uniform cooling.

[0007] Preferably, both ends of the pool body have upward-opening mounting grooves, and cylinders are installed inside the bottom side of each mounting groove. A carrying basket is assembled inside the pool body, and mounting seats are installed at the middle of the bottom side of both ends of the carrying basket. The working end of the cylinder is installed inside the mounting seat through a pin engagement. The vertical lifting and lowering of the carrying basket is achieved by the extension and retraction of the cylinder, which facilitates the removal of plastic particles.

[0008] Preferably, a fixed frame is installed on the top side of the bearing basket, a reciprocating motor is installed on one side of the fixed frame, a threaded rod is installed at the output end of the reciprocating motor, a slide rail is provided inside the top side of the fixed frame, a slider is slidably installed inside the slide rail, and a mounting block is installed on the bottom side of the slider. The reciprocating motor drives the threaded rod to rotate, causing the slider to slide horizontally within the slide rail, thereby realizing the horizontal movement of the stirring component inside the bearing basket, further expanding the stirring range and improving the cooling effect.

[0009] Preferably, a support seat is installed on the outer side of the top of the cylinder's actuating rod, and a telescopic rod is installed on the bottom side of one end of the support seat. U-shaped seats are installed on the bottom sides of both ends of the bearing basket. The actuating ends of the telescopic rod are respectively installed inside the U-shaped seats through a pin engagement. By shortening the telescopic rod, one end of the bearing basket moves downward, thereby tilting one end of the bearing basket to facilitate material discharge.

[0010] Preferably, a water inlet pipe is connected to one side of the top of the pool body, and a drain pipe is connected to one side of the bottom of the pool body. Valves are installed on the outside of both the water inlet pipe and the drain pipe. A movable door is installed on one side of the carrying basket through a hinge. A fixed handle is installed on one side of the movable door. The water inlet pipe and the drain pipe facilitate the replacement of coolant and ensure the cooling effect. The design of the movable door and the fixed handle facilitates the unloading of the cooled plastic particles.

[0011] Preferably, a control panel is installed on one side of the pool body. The control panel is electrically connected to the electrical components inside the device and is used to control the operation of the electrical components inside the device, thereby realizing centralized control of the electrical components inside the device.

[0012] The advantages of this utility model are:

[0013] 1. The present invention uses a drive motor to rotate an incomplete gear. Through alternating meshing with the gear teeth, the drive motor pushes the mounting cavity to slide along the slide groove, causing the stirring assembly to perform a small range of reciprocating motion in the horizontal direction. At the same time, the stirring motor drives the rotating shaft and stirring blades to rotate, stirring the coolant and particles. When the rotating shaft rotates, it not only drives the connecting plate to make the stirring blades rotate, but also causes the stirring blades to rotate on their own axis through the meshing of the drive gear and the driven gear. The horizontal movement of the stirring assembly and the rotation of the stirring blades and stirring blades work together to enhance the relative movement between the particles and the coolant, improve the heat exchange efficiency, and ensure uniform cooling.

[0014] 2. In this utility model, the cylinder's actuating rod extends, driving the carrying basket to rise vertically through the mounting base until the carrying basket reaches a suitable position at the top of the pool. The telescopic rod then shortens, pulling one end of the carrying basket downwards, causing it to tilt and facilitating the discharge of plastic particles. The fixed handle on one side of the movable door opens the movable door via a hinge, allowing the nylon plastic particles in the tilted state to slide out of the carrying basket under gravity, completing the unloading operation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-3As shown, a cooling tank for nylon plastic particle production includes a tank body 1. A mounting block 2 is installed directly above the tank body 1. A mounting frame 3 is installed on the bottom side of the mounting block 2. A drive motor 4 is installed on the top inner wall of the mounting frame 3. An incomplete gear 5 is installed at the output end of the drive motor 4. Sliding grooves 6 are formed inside both sides of the mounting frame 3. Sliding blocks 7 are slidably installed inside the sliding grooves 6. A mounting cavity 8 is installed between the two sides of the sliding blocks 7. Six teeth 9 are equidistantly installed on the inner walls of both sides of the top of the mounting cavity 8. During operation, the incomplete gear 5 engages with the teeth on one side of each cavity. 9. The stirring motor 10 is installed on the bottom side of the mounting cavity 8. The output end of the stirring motor 10 is installed with a rotating shaft 11. Three stirring blades 12 are installed at equal intervals at the bottom end of the rotating shaft 11. A drive gear 13 is installed at the top end of the rotating shaft 11. A connecting plate 14 is installed at the top end of the rotating shaft 11. A connecting shaft 15 is rotatably installed inside both ends of the connecting plate 14. Three sets of stirring blades 16 are installed at equal intervals on the outer side of the connecting shaft 15. A driven gear 17 is installed at the top end of the connecting shaft 15. The drive gear 13 and the driven gear 17 mesh with each other.

[0024] A fixing frame 22 is installed on the top side of the support basket 20. A reciprocating motor 23 is installed on one side of the fixing frame 22. A threaded rod 24 is installed at the output end of the reciprocating motor 23. A slide rail 25 is opened inside the top side of the fixing frame 22. A slider 26 is slidably installed inside the slide rail 25. The mounting block 2 is installed on the bottom side of the slider 26. A control panel 35 is installed on one side of the pool body 1. During operation, in practical applications, when the particles are cooled, they are usually placed statically in the cooling pool. The speed at which the heat on the particle surface is transferred to the coolant will be slowed down, reducing the cooling efficiency. Moreover, the accumulation of particles will lead to poor local cooling effect, affecting the overall cooling quality. The nylon plastic particles to be cooled are placed into the support basket 20, and the drive motor 4 is started. The drive motor 4 drives the incomplete gear 5 to rotate. During the rotation of the incomplete gear 5, it will alternately mesh with the teeth 9 on both sides of the top of the mounting cavity 8. When the gear 5 meshes with the tooth 9 on one side, it pushes the mounting cavity 8 to slide along the slide groove 6, thereby causing the sliding block 7 to slide within the slide groove 6, making the stirring assembly reciprocate in a small range in the horizontal direction. At the same time, the stirring motor 10 starts, and the output end of the stirring motor 10 drives the rotating shaft 11 to rotate. The stirring blade 12 at the bottom of the rotating shaft 11 rotates accordingly, stirring the coolant and nylon plastic particles. When the rotating shaft 11 rotates, it drives the connecting plate 14 to rotate, causing the stirring blade 16 to make a circular motion within the carrying basket 20. At the same time, the rotating shaft 11 drives the driving gear 13 to rotate. The driving gear 13 meshes with the driven gear 17, driving the connecting shaft 15 to rotate. The stirring blade 16 also makes a rotational motion. The synchronous rotation of the stirring blade 12 and the stirring blade 16, combined with the interaction of the three, effectively enhances the relative motion between the particles and the coolant, improves the heat exchange efficiency, reduces the dead corners of particle accumulation, and ensures cooling uniformity.

[0025] When the reciprocating motor 23 starts, it drives the threaded rod 24 to rotate. When the threaded rod 24 rotates, it drives the slider 26 to slide horizontally within the slide rail 25, which in turn drives the installation block 2 to move. This enables the stirring component to move horizontally within the bearing basket 20, further expanding the stirring range and improving the cooling effect.

[0026] Please see Figure 1 , 2 As shown in Figures 4 and 5, both ends of the pool body 1 are provided with upward-facing mounting grooves 18. Cylinders 19 are installed inside the bottom side of each mounting groove 18. A carrying basket 20 is assembled inside the pool body 1. Mounting seats 21 are installed at the middle position of the bottom side of both ends of the carrying basket 20. The working end of the cylinder 19 is installed inside the mounting seat 21 through a pin engagement.

[0027] A support seat 27 is installed on the outer side of the top of the cylinder 19's rod. A telescopic rod 28 is installed on the bottom side of one end of the support seat 27. U-shaped seats 29 are installed on the bottom side of both ends of the bearing basket 20. The working ends of the telescopic rod 28 are respectively installed inside the U-shaped seats 29 through a pin engagement.

[0028] A water inlet pipe 30 is connected to one side of the top of the pool body 1, and a drain pipe 31 is connected to one side of the bottom of the pool body 1. Valves 32 are installed on the outside of both the water inlet pipe 30 and the drain pipe 31. A movable door 33 is installed on one side of the carrying basket 20 through a hinge. A fixed handle 34 is installed on one side of the movable door 33. During operation, in the production process of nylon plastic particles, after extrusion and cutting, the internal temperature of the plastic particles is high. If they are not cooled in time, the particles will become viscous due to the high temperature and easily stick together to form clumps, which will affect the appearance of the particles. Therefore, a cooling pool is needed. By opening the valve 32, the water inlet pipe 30 injects coolant into the pool body 1 to complete the filling of coolant.

[0029] After the nylon plastic particles have cooled, cylinder 19 is activated. The rod of cylinder 19 extends and drives the carrying basket 20 to rise vertically through mounting base 21 until the carrying basket 20 is raised to a suitable position at the top of the pool body 1. Then, telescopic rod 28 is activated and the rod of telescopic rod 28 shortens. Since the working end of telescopic rod 28 is installed inside U-shaped base 29 through a pin, it will pull one end of carrying basket 20 downward, causing one end of carrying basket 20 to tilt, which facilitates the discharge of plastic particles. The fixed handle 34 on one side of the movable door 33 opens the movable door 33 through a hinge. The nylon plastic particles in the tilted state slide out of the carrying basket 20 under the action of gravity, completing the unloading operation.

[0030] After unloading is completed, close the movable door 33. If the coolant needs to be replaced, open the valve 32 of the drain pipe 31 to drain the coolant in the pool 1. After draining, close the valve 32 of the drain pipe 31 and then re-inject new coolant through the water inlet pipe 30. After filling, close the valve 32 to prepare for the next cooling operation. After unloading is completed, start the cylinder 19. The rod of the cylinder 19 shortens and drives the bearing basket 20 to descend vertically through the mounting base 21, so that the bearing basket 20 returns to the initial return position of the pool 1.

[0031] Working principle: By opening valve 32, coolant is injected into the tank 1 through inlet pipe 30, thus completing the filling of coolant.

[0032] The nylon plastic particles to be cooled are placed into the support basket 20. The drive motor 4 is started, and the drive motor 4 drives the incomplete gear 5 to rotate. During the rotation of the incomplete gear 5, it will alternately mesh with the teeth 9 on both sides of the inner wall of the top of the mounting cavity 8. When the incomplete gear 5 meshes with one side of the teeth 9, it will push the mounting cavity 8 to slide along the slide groove 6, thereby driving the sliding block 7 to slide in the slide groove 6, so that the stirring component makes a small range of reciprocating motion in the horizontal direction. At the same time, the stirring motor 10 is started, and the output end of the stirring motor 10 drives the rotating shaft 11 to rotate. The stirring blades at the bottom of the rotating shaft 11 As the rotating shaft 11 rotates, it stirs the coolant and nylon plastic particles. When the rotating shaft 11 rotates, it drives the connecting plate 14 to rotate, causing the stirring blade 16 to make a circular motion within the bearing basket 20. At the same time, the rotating shaft 11 drives the drive gear 13 to rotate. The drive gear 13 meshes with the driven gear 17, driving the connecting shaft 15 to rotate. The stirring blade 16 also rotates on its own axis. The synchronous rotation of the stirring blade 12 and the stirring blade 16, combined with the interaction of the three, effectively enhances the relative motion between the particles and the coolant, improves the heat exchange efficiency, reduces the dead corners of particle accumulation, and ensures cooling uniformity.

[0033] When the reciprocating motor 23 starts, it drives the threaded rod 24 to rotate. When the threaded rod 24 rotates, it drives the slider 26 to slide horizontally within the slide rail 25, which in turn drives the installation block 2 to move. This enables the stirring component to move horizontally within the bearing basket 20, further expanding the stirring range and improving the cooling effect.

[0034] After the nylon plastic particles have cooled, cylinder 19 is activated. The rod of cylinder 19 extends and drives the carrying basket 20 to rise vertically through mounting base 21 until the carrying basket 20 is raised to a suitable position at the top of the pool body 1. Then, telescopic rod 28 is activated and the rod of telescopic rod 28 shortens. Since the working end of telescopic rod 28 is installed inside U-shaped base 29 through a pin, it will pull one end of carrying basket 20 downward, causing one end of carrying basket 20 to tilt, which facilitates the discharge of plastic particles. The fixed handle 34 on one side of the movable door 33 opens the movable door 33 through a hinge. The nylon plastic particles in the tilted state slide out of the carrying basket 20 under the action of gravity, completing the unloading operation.

[0035] After unloading is completed, close the movable door 33. If the coolant needs to be replaced, open the valve 32 of the drain pipe 31 to drain the coolant in the pool 1. After draining, close the valve 32 of the drain pipe 31 and then re-inject new coolant through the water inlet pipe 30. After filling, close the valve 32 to prepare for the next cooling operation. After unloading is completed, start the cylinder 19. The rod of the cylinder 19 shortens and drives the bearing basket 20 to descend vertically through the mounting base 21, so that the bearing basket 20 returns to the initial return position of the pool 1.
