Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically a plastic granule cooling device. Background Technology

[0002] Plastic granules can be made into many different objects. The production process of plastic granules requires multiple steps such as heating, extrusion and cooling. In order to avoid the temperature from getting too high and melting, and to prevent the granules from sticking together, there are generally two ways to cool down plastic granules: water cooling and air cooling.

[0003] For example, a Chinese patent with publication number CN219968510U discloses a water tank for cooling plastic particles. When cooling plastic particles, a lifting drive device 1 drives the mesh cover to shake up and down, while a lifting drive device 2 drives the mesh cover to tilt and swing left and right, thereby achieving a multi-directional shaking effect on the circular mesh cover, which makes the cooling of plastic particles more uniform.

[0004] The aforementioned patent still has the following drawbacks: mixing plastic particles by shaking the mesh cannot fully mix the plastic particles inside the mesh, resulting in low dispersion of the plastic particles inside the mesh, which reduces the contact area between the plastic particles and the cooling water, thereby reducing the cooling efficiency; in addition, the aforementioned patent cannot quickly remove the water from the plastic particles inside the mesh when draining the plastic particles, and the draining efficiency also needs to be improved. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this utility model is to provide a plastic granule cooling device that can effectively improve the cooling efficiency and drainage efficiency of plastic granules.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plastic granule cooling device includes a frame, a water tank installed at the bottom of the frame, two sets of hydraulic cylinders fixedly connected to the top of the frame, and a sealing plate disposed below the two sets of hydraulic cylinders. A horizontal sliding groove is formed on the sealing plate, and a slider is slidably connected within the groove. One set of hydraulic cylinders is hinged to the sealing plate, and the other set of hydraulic cylinders is hinged to the slider. A motor is installed on the top of the sealing plate, and a circular draining component is horizontally rotatably connected below the sealing plate. A material gate is installed on one side of the draining component. The motor is drivenly connected to the draining component.

[0008] Preferably, the draining component includes a circular mesh cover and two annular fixing frames. The two annular fixing frames are rotatably connected to the bottom sides of the sealing plate, and a connecting rod is fixed between the two annular fixing frames. The circular mesh cover is fixed inside the two annular fixing frames. A connecting plate is fixed to the annular fixing frame closer to the motor. A rotating shaft is fixed to the middle of the connecting plate. The rotating shaft is connected to the motor via a belt. The material gate is installed on the side of the annular fixing frame away from the motor.

[0009] Preferably, two splash guards are fixedly connected to the bottom surface of the sealing plate.

[0010] Preferably, the inner wall of the circular mesh cover is fixedly connected with multiple material-turning plates along its axial direction.

[0011] Preferably, it also includes a pusher plate disposed inside the circular mesh cover near the connecting plate, the pusher plate being in contact with the inner wall of the circular mesh cover, and a pull rod being fixedly connected to the side of the pusher plate away from the connecting plate.

[0012] Preferably, a limiting ring is coaxially installed in the annular fixed frame away from the connecting plate, and an installation rod is fixedly connected between the limiting ring and the annular fixed frame. The pull rod is coaxially slidably connected to the limiting ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Overall, by setting up two sets of hydraulic cylinders, sealing plates, chutes, sliders, circular draining components, and motors, the dispersion of plastic particles within the draining components can be improved during plastic particle cooling, increasing the contact area between the plastic particles and the cooling water, thus improving the cooling efficiency of the plastic particles.

[0022] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Please refer to Figure 1 - Figure 4 This embodiment provides a plastic granule cooling device, including a frame 1, a water tank 2 installed at the bottom of the frame 1, and cooling water filled in the water tank 2. To ensure that the temperature of the cooling water remains low, a water circulation device or a refrigeration device can be installed at the water tank 2 to ensure that the temperature of the cooling water remains stable at a low temperature. Two sets of hydraulic cylinders 3 are fixedly connected to the top of the frame 1, and a sealing plate 4 is also included below the two sets of hydraulic cylinders 3. A horizontal sliding groove 41 is opened on the sealing plate 4, and a slider 5 is slidably connected in the sliding groove. One set of hydraulic cylinders 3 is hinged to the sealing plate 4, and the other set of hydraulic cylinders 3 is hinged to the slider 5. A motor 6 is installed on the top of the sealing plate 4, and a circular draining component 7 is horizontally rotatably connected below the sealing plate 4. A material gate 8 is installed on one side of the draining component 7. The motor 6 is connected to the draining component 7 through a transmission.

[0024] Specifically, the draining component 7 includes a circular mesh cover 71 and two annular fixing frames 72. The two annular fixing frames 72 are rotatably connected to the bottom sides of the sealing plate 4, and a connecting rod 73 is fixed between the two annular fixing frames 72. The circular mesh cover 71 is fixed inside the two annular fixing frames 72. A connecting plate 74 is fixed to the annular fixing frame 72 near the motor 6. A rotating shaft 75 is fixed in the middle of the connecting plate 74. Pulleys are installed at the ends of the rotating shaft 75 and the motor 6 shaft. A belt 9 is wrapped around the two pulleys. The motor 6 and the rotating shaft 75 are connected by transmission through the belt 9. The material gate 8 is installed on the annular fixing frame 72 away from the motor 6.

[0025] The following is a further explanation based on a specific application scenario. When cooling plastic granules, firstly, control the two sets of hydraulic cylinders 3 to retract synchronously, raising the draining component 7 to a height convenient for workers to feed the material. Then, first open the material gate 8 and feed the plastic granules into the circular mesh cover 71 of the draining component 7. Once the circular mesh cover 71 is full of plastic granules, close the material gate 8. Then, control the two sets of hydraulic cylinders 3 to extend synchronously, so that the circular mesh cover 71 of the draining component 7 submerges the cooling water in the water tank 2. At this time, the sealing plate 4 seals the water tank 2. Next, start the motor 6 to control the entire draining component 7 to rotate. During the rotation of the circular mesh cover 71 of the draining component 7, the plastic granules inside the circular mesh cover 71 are stirred. This not only makes the distribution of plastic granules inside the circular mesh cover 71 more dispersed but also stirs the cooling water in the water tank 2, making the contact between the plastic granules and the cooling water more uniform, thereby improving the cooling efficiency of the plastic granules.

[0026] After the plastic granules cool down, the two sets of hydraulic cylinders 3 are controlled to contract synchronously, so that the draining part 7 is completely separated from the cooling water. Driven by the motor 6, the circular mesh cover 71 rotates rapidly, which not only makes the distribution of plastic granules inside the circular mesh cover 71 more dispersed, but also makes the water on the plastic granules quickly thrown to the outside under the action of centrifugal force, thereby improving the draining efficiency of the plastic granules.

[0027] Furthermore, after the draining process is completed, the motor 6 is turned off and the material gate 8 is opened. Then, the hydraulic cylinder 3 on the side closest to the material gate 8 is extended, while the hydraulic cylinder 3 on the side furthest from the material gate 8 is retracted or remains unchanged. This causes the circular mesh cover 71 to slowly tilt, allowing the plastic granules to be discharged from the material gate 8. It is important to explain the function of the slider 5 and the chute: Since the tops of both sets of hydraulic cylinders 3 are fixed to the frame 1, they are always vertically parallel. Without the cooperation of the slider 5 and the chute, there would be no height difference between the ends of the two sets of hydraulic cylinders 3, making it impossible to tilt the circular mesh cover 71, which would be inconvenient for unloading. The slider 5 and the chute, through their cooperation, ensure that when the set of hydraulic cylinders 3 closest to the material gate 8 extends, the slider 5's position in the chute allows that set of hydraulic cylinders 3 to extend smoothly, thus ensuring that the circular mesh cover 71 can gradually tilt for easy unloading.

[0028] Overall, by setting up two sets of hydraulic cylinders 3, sealing plates 4, sliding grooves, sliders 5, circular draining parts 7, and motors 6, the dispersion of plastic particles within the draining parts 7 can be improved during plastic particle cooling, increasing the contact area between the plastic particles and the cooling water, thus improving the cooling efficiency of the plastic particles. During draining, the motor 6 drives the circular mesh cover 71 to rotate rapidly, which not only makes the distribution of plastic particles within the circular mesh cover 71 more dispersed, but also allows the water on the plastic particles to be quickly thrown to the outside under the action of centrifugal force, thereby improving the draining efficiency of the plastic particles.

[0029] Reference Figure 1 Two splash guards 10 are fixed to the bottom surface of the sealing plate 4, and a circular mesh cover 71 is located between the two splash guards 10.

[0030] In specific usage scenarios, since the circular mesh cover 71 rotates rapidly during the draining process, the water carried by the plastic particles is easily splashed to the outside, making the ground slippery and posing a certain safety hazard. In this embodiment, two splash guards 10 are fixed to the bottom surface of the sealing plate 4, so that the splashed water droplets can be blocked during draining, allowing the drained water to return to the water tank 2 along the splash guards 10.

[0031] Reference Figure 3 and Figure 4 Multiple material-turning plates 11 are fixedly connected to the inner wall of the circular mesh cover 71 along its axial direction.

[0032] Depending on the specific application scenario, the material-turning plate 11 can further disperse the distribution of plastic granules within the circular mesh cover 71, increasing the contact area between the plastic granules and cold water to a certain extent, thereby improving the cooling efficiency of the plastic granules. Furthermore, during drainage, the increased dispersion of the plastic granules also improves the drainage efficiency.

[0033] Reference Figure 3 and Figure 4 To facilitate the unloading of the high-speed particles, a pusher plate 121 is provided inside the circular mesh cover 71 near the connecting plate 74. The pusher plate 121 contacts the inner wall of the circular mesh cover 71, and a pull rod 122 is fixedly connected to the side of the pusher plate 121 away from the connecting plate 74. Furthermore, a limit ring 131 is coaxially installed in the annular fixing frame 72 away from the connecting plate 74. An installation rod 132 is fixedly connected between the limit ring 131 and the annular fixing frame 72, and the pull rod 122 is coaxially slidably connected to the limit ring 131. It should be noted that, due to the setting of the tipping plate, an adaptation groove 1211 should be opened on the pusher plate, and the groove wall of the adaptation groove 1211 contacts the tipping plate.

[0034] In specific application scenarios, the mesh openings on the circular mesh cover 71 obstruct the unloading of plastic granules. Therefore, if the plastic granules rely solely on their own weight to be unloaded from the material gate 8, a significant amount of residual plastic granules may remain inside the circular mesh cover 71. However, in this embodiment, after opening the material gate 8, the pusher plate 121 pushes the plastic granules out of the material gate 8 by pulling the pull rod 122. This not only improves unloading efficiency but also reduces the amount of residual plastic granules inside the circular mesh cover 71 due to the contact between the pusher plate 121 and the inner wall of the circular mesh cover 71, thus further improving the unloading efficiency. Furthermore, the limiting ring 131 and the mounting rod 132 are designed to ensure the stability of the pusher plate 121's movement along the axial direction of the circular mesh cover 71 when the pull rod 122 is pulled.

[0035] Reference Figure 3 and Figure 4 To facilitate unloading, a booster 14 is fixedly connected to the connecting plate 74. The booster 14 includes a booster plate 141 disposed between the connecting plate 74 and the pusher plate 121, and a plurality of first springs 142 are installed between the booster plate 141 and the connecting plate 74.

[0036] Depending on the specific application scenario, when plastic granules are put into the circular mesh cover 71 and the material gate 8 is closed, a force will be generated on the pull rod 122 from the material gate 8 toward the connecting plate 74, causing the push plate 121 to press against the connecting plate 74 and compress the first spring 142. When it is time to discharge the material, the material gate 8 is opened, and the push plate 121 will be pushed toward the material gate 8 under the elastic force of the first compression spring, thus exposing the pull rod 122 to the outside, making it convenient for the staff to pull the pull rod 122 to unload the plastic granules from the circular mesh cover 71.

[0037] Reference Figure 1 and Figure 2To further improve the installation stability of the sealing plate 4, a number of auxiliary reinforcement components 15 are installed between the top of the frame 1 and the sealing plate 4. The auxiliary reinforcement components 15 include an upper sleeve 151 hinged to the top of the frame 1 and a lower sleeve 152 hinged to the sealing plate 4, and the upper sleeve 151 and the lower sleeve 152 are sleeved together. A number of second springs 153 are installed between the top of the frame 1 and the sealing plate 4, and the second springs 153 are looped around the outside of the upper sleeve 151.

[0038] Based on the specific application scenario, the auxiliary reinforcement 15 can first increase the connection strength between the frame 1 and the sealing plate 4, providing more stable support for the cooling and drainage of plastic particles.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
